Findings Of Fact Based upon the oral and documentary evidence adduced at the final hearing and the entire record in this proceeding, the following findings of fact are made: The SFWMD is a public corporation in the state of Florida existing by virtue of Chapter 25270, Laws of Florida, 1949, and operating pursuant to Chapter 573, Fla. Stat., and Title 40E, Fla. Admin. Code, as a multi-purpose water management district, with its principal office in West Palm Beach, Florida. The Navy has proposed construction of a naval housing facility on the Peary Court site (the "Site") in Key West, Florida. The Site is approximately 25.89 acres and will provide 160 housing units for junior enlisted Navy and Air Force personnel and their families. The Site is the center of a larger, 37 acre drainage basin. The Site was formerly the location of military housing. However, for the past 18 years, the Site had been used by the City of Key West, with the assent of the Navy, for active and passive recreation for city residents. The Site contains a cemetery of historic value and a former military housing structure now being used by the Navy Key West Federal Credit Union with an associated parking area of paved asphalt. On February 6, 1992, the Navy submitted an application for a Surface Water Management District General Permit for the Project. The proposed surface water management system (the "System") was designed by Rice Creekmore, a registered professional engineer, and his company Johnson, Creekmore, and Fabray. The proposed System utilizes the existing topography and incorporates a number of drainage control mechanisms to manage the run-off from the Site. The System employs inlets, swales and culverts to direct stormwater run-off into dry detention areas (ponds) for pretreatment prior to discharging into seven 24-inch Class V injection wells (drainage wells). As discussed below, these injection wells must be permitted by the Florida Department of Environmental Regulation ("FDER"). The dry pond areas utilize key ditches, bottom elevation 1.0' NGVD, in order to hydraulically connect all of the dry pond areas together into one dry system prior to overflowing into the drainage wells beginning at elevation 1.5' NGVD. In other words, the detention ponds are interconnected with pipes. The design includes only one point where run-off would be discharged from the Site during any storm equal to a 25 year, three day storm event. That discharge would occur at the lowest point of the Site at the corner of Eisenhower and Palm. The water would be discharged through a V notch weir (the "Weir") into the City's stormwater system. An existing 12" storm drain line at the discharge point will be replaced by a 13.5" by 22.0" Reinforced Concrete Elliptical Pipe culvert. As discussed in more detail below, the System is designed so as to detain 1" of run-off within the dry detention ponds prior to any discharge through the Weir. After review of the application and submittals, the SFWMD issued a Notice of Intent to issue General Permit and Stormwater Discharge Certification No. 44-00178-S (the "Permit") on September 29, 1992. Petitioner and Intervenor timely petitioned for an administrative hearing challenging the SFWMD decision to award the Permit. There is no dispute as to the standing of either Petitioner or Intervenor. The SFWMD has adopted rules that set forth the criteria which an applicant must satisfy in order for a surface water management permit to issue. The criteria are set forth in Rule 40E-4, Florida Administrative Code. Rule 40E-4.301(1)(m) and 40E-4.091(1)(a) incorporate by reference The Basis of Review for Surface Water Management Permit Applications within South Florida Water Management District - April, 1987, ("The Basis for Review"). The Basis for Review explicates certain procedures and information used by the SFWMD staff in reviewing a surface water management permit application. The SFWMD issues general permits for projects of 40 acres or less that meet specific criteria. All other projects must obtain individual permits which are reviewed by the District Board. The specific rules relating only to general permits are set forth in Rule 40E-40. In addition, the Basis for Review sets forth certain technical requirements which must be met for the issuance of a general permit including general construction requirements and special requirements for wetlands. The Basis for Review also sets forth criteria for how a proposed system should address water quantity and water quality issues. The SFWMD assumes that water quantity and water quality standards will be met if a system satisfies the criteria set forth in the Basis for Review. Water Quantity Criteria Rule 40E-4.301(a), Florida Administrative Code, requires an applicant to provide reasonable assurances that a surface water management system will provide adequate flood protection and drainage. The purpose of the water quantity criteria is to insure that pre- development flows and post-development flows are equal. The SFWMD requires calculations of a project's projected post-development flow to guarantee that the post-development discharge rate will not be in excess of the pre-development discharge rate. These calculations are based on a 25 year, 3 day storm event. There is no stormwater management system in place at the Project Site. The pre-development topography results in a pre-development discharge point from the Site at the corner of Eisenhower Drive and Palm Avenue. At this point, a discharge or outfall pipe leads into the City of Key West's stormwater management system. The City's system ultimately discharge into Garrison Bight, a nearly waterbody which is discussed in more detail below. At the time the Navy began planning for the Project, the Navy was told that the discharge pipe had a capacity of accepting water at a rate of 40 cubic feet per second ("CFS"). The Navy initially designed a system to utilize this capacity. Subsequently, it was discovered that, due to the size of the pipe at the discharge point and the capacity of the pipes downstream in the City of Key West's stormwater management system, the City would not allow or accommodate a discharge of more than 11 CFS from the Site. Thus, the System had to be redesigned so that the discharge to the City's system would not exceed 11 CFS. The system was redesigned to incorporate the seven (7) Class V injection wells. The injection wells are intended to insure that discharge from the Project into the City stormwater system through the surface water discharge pipe at Eisenhower Drive and Palm Avenue will not exceed 11 CFS. The injection wells introduce treated stormwater into the ground before it reaches the discharge point. The pre-development rate of surface water discharge from Peary Court in a 25 year, 72 hour storm event was 55 CFS. This rate was calculated based upon a site survey, a determination of the existing amount of pervious versus impervious surface area, and a calculation made through a generally accepted civil-engineering computer program. 1/ This predevelopment discharge is the amount of water which would be expected to discharge off-site after percolation occurs. The number and size of the injection wells for the proposed system were determined based upon tests of an on-site twelve-inch fire well. The results of the tests revealed that the on-site test well could manage in excess of 2 CFS. Due to test limitations, the exact capacity could not be measured, but the capacity was clearly more than 2 CFS. These results were then compared with data obtained from the engineering firm of Post, Buckeley, Schuh & Jernigan for installed wells in the Florida Keys of a similar nature and size to the wells in the proposed surface water management system. The Post, Buckeley test results indicated that 24-inch wells had a capacity of 31 CFS. In addition, the design engineer consulted with South Florida Well Drillers, who have drilled other wells in the Florida Keys including 24-inch wells at the Key West airport which were completed shortly before the application for this Project. South Florida Well drillers found the capacity of 24-inch wells in Key West to be in the 25 to 30 CFS range. Based upon the results of the test well and the related reports described above, the project engineer based his design of the surface water management system on an estimated well capacity of 8.4 CFS for each well. These estimates were submitted by the Navy in its application and were appropriately determined to be reasonable by the SFWMD staff. Indeed, the evidence established that 8.4 CFS was a conservative estimate. The seven injection wells, at an estimated capacity of approximately 8.4 CFS each, provide in excess of 56 CFS of well discharge capacity, which is beyond the necessary discharge volume for the Project. Limiting Condition No. 13 of the Permit requires the Navy to obtain a well capacity test from a Florida Registered Professional Engineer or Professional Geologist following the installation of the first Class V injection well at the Site. If the results of this test indicate that the capacity of the well is different than that submitted by the Navy in its application, the Navy must apply for a permit modification to provide a design which incorporates a representative injection well flow-rate and an appropriate number of wells for the Site. In view of the reasonableness of the capacity rates utilized for the wells, it is unlikely that the results of the capacity test will result in any major design change in the proposed surface water management system. The use of the injection wells in the proposed surface water management system will significantly reduce the amount of run-off which would otherwise reach Garrison Bight from the Site. After the System is completed, it is expected that the amount of run-off from the Site that will reach Garrison Bight will be only 20 percent of the predevelopment amount. In addition, because there has previously been no management of the run-off from the Site and surrounding areas, there has been a frequent flooding problem at the corner of Eisenhower Drive and Palm Avenue after heavy rain storms. The proposed surface water management system will accommodate the overflow of water which historically occurred when discharges from Peary Court and the surrounding areas could not be accommodated by the Key West storm water management system. Petitioner and Intervenor suggest that the effect of tidal flow on the capacity of the wells was not fully considered. The evidence established that the design engineer considered normal high tides in calculating groundwater elevations. Respondent's engineering experts have concluded that the proposed surface water management system is effectively designed to accommodate the Florida Keys' tidal flows. Petitioner and Intervenor offered no expert testimony to refute this conclusion and/or to establish that the tides would impact the effectiveness of the proposed surface water management system. In the event that an extremely high tide occurs at the time of a storm, the detention ponds may hold standing water for a short time. This water would not be discharged off-site. There is no evidence that tidal influences would in any way adversely affect the System's ability to uptake pollutants in the "first- flush". The Class V shallow injection wells are an integral part of the proposed Peary Court surface water management system. Without the injection wells it is not clear whether the Project could meet the SFWMD water quantity criteria. The SFWMD does not have authority to permit Class V injection wells. FDER must permit those wells. The Peary Court site is not the first Florida Keys' project permitted by the SFWMD which utilizes injection wells. The surface water management permits for the other projects were issued contingent upon obtaining the necessary permits for the injection wells. Special Condition No. 14 of the Permit provides that the Permit is conditioned on the Applicant obtaining the applicable permits from FDER for the injection wells. During the interim while the Navy is seeking the FDER permits, it should be required to retain all run-off on-site. If the Navy is not able to obtain the necessary FDER permits for the injection wells, the Navy should be required to either retain all run-off on-site or propose an alternate design to meet the SFWMD's water quantity requirements. A modified permit application with a new Notice of Intent should be required for any alternate design. The following Special Condition Number 14 was offered by the SFWMD at the hearing (language revised from original condition is highlighted and underlined): THIS PERMIT IS ISSUED BASED ON THE APPLICANT OBTAINING THE NECESSARY CLASS V INJECTION WELL PERMITS FROM THE FLORIDA DEPARTMENT OF ENVIRONMENTAL REGULATION (FDER). THE PERMITTEE SHALL SUBMIT AN APPROVED CLASS V DRAINAGE WELL PERMIT FROM FDER PRIOR TO OPERATION OF THE SURFACE WATER MANAGEMENT SYSTEM. IN THE INTERIM, THE PERMITTEE SHALL CERTIFY TO THE DISTRICT THAT NO OFF-SITE DISCHARGE WILL OCCUR UNTIL THE APPROVED CLASS V DRAINAGE WELLS ARE IN OPERATION. IF THE SURFACE WATER MANAGEMENT SYSTEM DESIGN MUST BE MODIFIED AS A RESULT OF FDER REQUIREMENTS OR IF THE CLASS V INJECTION WELL PERMITS ARE NOT ISSUED, THE APPLICANT SHALL APPLY FOR A PERMIT MODIFICATION TO PROVIDE A SURFACE WATER MANAGEMENT SYSTEM DESIGN WHICH SHALL MEET DISTRICT CRITERIA IN EFFECT AT THAT TIME. The proposed additional language requires the Navy to certify that no off-site discharges will occur until the injection wells are permitted and are operating. This revised language should be added to Special Condition No. 14 to clarify that the injection wells must be in operation prior to any off-site discharge from the surface water management system. Maintenance of the surface water management system entails upkeep of the dry detention areas and routine grass cutting, as well as inspection of the injection wells on a periodic basis to guard against clogging and reduced capacity. The system is essentially designed to operate without direct surveillance or intervention. Injection wells do not require any additional maintenance over and above that which is routinely required for other types of surface water management systems. The injection wells will require routine maintenance to ensure that manholes and inlets do not become clogged. Limiting Condition No. 8 of the Permit requires that the surface water management system, including the injection wells, be maintained. At the hearing, the SFWMD proposed that a condition be added to the Permit to further clarify the maintenance requirements. A condition requiring long-term maintenance would be desirable and reasonable. A new special condition should be added to the Permit requiring long-term maintenance of grass swales and inspections of injection wells for clogging. Acceptable language for such a condition would be: SPECIAL CONDITION NO. 15 The permittee shall provide long-term maintenance of the surface water management system, encompassing the injection wells, including, but not limited to, (a) maintenance of the vegetation in the grass swales and detention ponds and (b) routine inspections of wells and discharge structures for clogging. Water Quality Criteria As noted above, there is no designed system for surface water management and/or water quality pretreatment at the Site in its undeveloped state. Surface water run-off that can not be managed by the City of Key West's storm water management system collects in roads adjacent to the Site, resulting in adverse water quality and quantity impacts to adjacent land and receiving waters. The applicable water quality criteria, contained in Rule 40E-4.301, Florida Administrative Code, require an applicant to provide reasonable assurances that a surface water management system will not cause adverse water quality impacts to receiving waters and adjacent lands, and will not cause discharge which results in any violation of the standards and criteria of Chapter 17-302 for surface waters of the state. Rule 40E-4.301 provides that: In order to obtain a permit under this chapter, an applicant must give reasonable assurances that the surface water management system is consistent with the State Water Policy as set forth in Chapter 17-40, Florida Administrative Code (40E-4.301(1)(h), Florida Administrative Code. Rule 17-40.420 provides in pertinent part: Minimum Stormwater Treatment Performance Standards. When a stormwater management system complies with rules establishing the design and performance criteria for stormwater management systems, there shall be a rebuttable presumption that such systems will comply with state water quality standards. The Department and the Districts, pursuant to Section 373.436, Florida Statutes, shall adopt rules that specify design and performance criteria for new stormwater management systems which: 1. Shall be designed to achieve at least 80 percent reduction of the average annual load of pollutants that would cause or contribute to violations of state water quality standards. The Basis for Review, which is incorporated into Title 40E, Florida Administrative Code, by reference, further delineates the applicable water quality permit criteria for surface water management systems. Regarding water quality criteria, the Basis for Review provides: 3.2.2.1 State standards - Projects shall be designed so that discharges will meet state water quality standards, as set forth in Chapter 17-3 [revised to 17-302], Florida Administrative Code. The SFWMD's water quality criteria do not require chemical testing of stormwater for residential projects. The SFWMD's water quality criteria require that the design of a surface water management system meet applicable design/technology based criteria. Section 3.2.2.2 of the Basis for Review contains the specific water quality criteria for the design of a surface water management system. The SFWMD allows applicants to design their surface water management system using either dry or wet detention or dry or wet retention, so long as the treatment provided by the system meets water quality and quantity criteria. Dry detention consists of a system of grass swales and vegetative- covered ponds which detain water at a predetermined rate prior to off-site discharge. Wet retention can contain canals, ditches, lakes or ponds to retain water on-site. If a system is designed to meet the criteria specified in 3.2.2.2(a) of the Basis for Review and incorporates Best Management Practices ("BMP's") for the type of system proposed, the SFWMD presumes that water quality standards will not be violated. In determining which system is appropriate for a particular site, water quantity (flooding impacts) and water quality impacts must be balanced. In some cases, water quantity concerns may preclude certain types of water quality treatment methods. At the hearing in this case, Petitioner and Intervenor suggested that retention is superior to detention in designing surface water management systems. The evidence presented in this case was insufficient to support this conclusion. In any event, this contention focuses only on water quality considerations. One drawback to retention is that it may have on-site flooding impacts. With respect to this Project, the evidence indicates that retention may not have been an acceptable alternative because of possible adverse water quantity impacts. The Navy's proposed surface water management system was designed to utilize dry detention with filtration for treatment of surface water prior to discharge into the injection wells and/or off-site. The design uses a system of grass swales and grass-covered detention ponds to detain and filter pollutants from the surface water as it makes its way through the dry detention system. The System is designed to utilize as many grass swale areas as possible to filter or treat the surface water before it reaches the detention ponds which provide further treatment. The swales restrict the flow of water to approxmiately one half to one foot per second which allows for percolation and a tremendous amount of filtration. The System utilizes the natural topography of the Site to direct water through the dry detention system to the lowest point of the Site at the corner of Eisenhower Drive and Palm Avenue. Any water which makes it to this last detention pond and is not drained into one of the injection wells can flow through the discharge structure (the Weir) at 11 CFS and ultimately make it into Garrison Bight. Petitioner and Intervenor have suggested that the design of the proposed System is defective because water discharged from the cul-de-sacs in the Project design will flow directly into detention ponds without passing over any of the grass swales. The permit criteria do not specify that all surface water must contact grass swales prior to reaching a detention pond. While greater filtration is achieved the longer the run-off remains in the system, the evidence established that the detention ponds by themselves provide sufficient water quality treatment. With respect to all but one of the cul-de-sacs, the water must pass through at least two detention ponds before it is discharged. Run-off from the cul-de-sac closest to the Weir will receive treatment only in the last discharge pond. Petitioner and Intervenor questioned whether the run- off from this last cul-de-sac will receive adequate treatment, in other words, whether the "first flush" will be adequately detained prior to discharge, especially in circumstances when the detention pond is already wet. However, the evidence was insufficient to establish that their concerns are justified and/or that this situation would constitute a violation of water quality standards. This cul-de-sac is only 100 ft in diameter and accounts for no more than 8 percent of the total run-off from the Site. After considering all of the evidence, it is concluded that the water from the cul-de-sacs will be adequately treated in accordance with the permit criteria prior to any discharge. In assessing the Navy's proposed surface water management system the following criteria from the Basis for Review are pertinent in determining whether the proposed System will provide appropriate water quality treatment: 3.2.2.2 Retention and/or detention in the overall system, including swales, lakes, canals, greenways, etc., shall be provided for one of the three following criteria or equivalent combinations thereof. . .: Wet detention volume shall be provided for the first inch of run-off from the developed project, or the total run-off of 2.5 inches times the percentage of imperviousness, whichever is greater. Dry detention volume shall be provided equal to 75 percent of the above amounts computed for wet detention. If the receiving waterbody, is a "sensitive receiving water," which would include an Outstanding Florida Water, the following additional criteria regarding direct discharges are applicable: 3.2.2.2 d. Projects having greater than 40 percent impervious area and which discharge directly to sensitive receiving waters shall provide at least one half inch of dry detention or retention pretreatment as part of the required retention/detention. The SFWMD interprets the permitting criteria as creating a rebuttable presumption that a surface water management system that provides detention in accordance with BMP's of the first inch (1") of run-off from a Site, commonly referred to as the "first-flush", will meet state water quality standards. The "first-flush" occurs at the onset of a rainfall when most pollutants run off paved areas and percolate into the grass swales. It is an accepted design parameter that the "first flush" contains 90 percent of the pollutants which will be collected in the run-off. The 90 percent of the pollutants in the first flush are consequently retained on-site through pure percolation and never reach the discharge facility. Although Petitioner and Intervenor suggest that dry detention does not provide this degree of filtration, the evidence was insufficient to support this contention. The proposed System for this Project provides treatment for the first one inch (1") of run-off from the developed Project, thereby meeting the permitting criteria for sensitive receiving waters. Intervenor and Petitioner contend that the development of this Project will necessarily result in a larger amount of pollutants in the run-off from the Site. They argue that the Applicant has not provided reasonable assurances that capturing 90 percent of the increased level of pollutants in the first flush will meet water quality standards. As noted above, compliance with the permit criteria creates a rebuttable presumption that water quality standards will be met. Insufficient evidence was presented to overcome this rebuttable presumption. In calculating the appropriate volume for the dry detention ponds, the Project engineer used the Site's percentage of impervious area. The percentage of impervious area was determined in accordance with SFWMD criteria. The calculations do not account for any percolation from the impervious areas even though much of that run-off will pass through swales and other grassy areas of the Site. In addition, there is a built-in buffer between the berm elevation around the ponds and the expected water level in the ponds. These factors confirm that there is significant additional capacity in the ponds which is an overage or safety net. In sizing the detention ponds, the project engineer also factored in additional off-site water that will be coming on-site from Palm Avenue. This water currently ponds on Palm Avenue contributing to a recurring flooding problem in the area. This off-site water will be routed through an inlet and pumped directly into on-site detention areas thereby reducing flooding on Palm Avenue and providing some treatment for off-site run-off that was not previously treated before entering the City's stormwater system. As noted above, additional water quality criteria requirements apply to projects which discharge to an Outstanding Florida Water. These additional criteria are set forth in paragraph 40 above. Outstanding Florida Water or OFW is the designation given exclusively by the FDER to certain waterbodies in Florida which have special significance, either for ecological or recreational reasons. Outstanding Florida Waters are afforded the highest degree of water quality protection. The criteria for designation of waters as Outstanding Florida Waters is found in Chapter 17-302, Florida Administrative Code. When the SFWMD initially reviewed the Permit application for this Project, it erroneously assumed that Garrison Bight, the ultimate receiving body for the waters discharged from the project through the City stormwater system, was an OFW. Although the SFWMD applied water quality criteria for OFW's when it reviewed the subject permit application, the evidence at the hearing in this case established that Garrison Bight is not an Outstanding Florida Water. A FDER representative, qualified as an expert in the designation of Outstanding Florida Waters, testified that the Outstanding Florida Water designation does not apply to certain waterbodies that were degraded at the time of designation or did not have the significance or pristine water quality that merit special protection. The designation also does not apply to artificial waterbodies. Artificial waterbodies are defined in Rule 17-302.700(9)(i), Florida Administrative Code, as a waterbody created by dredging or excavation or by the filing in of its boundaries on at least two sides. The FDER has formally determined that Garrison Bight is not an Outstanding Florida Water because Garrison Bight is an artificial waterbody in accordance with the definition. Furthermore, Garrison Bight is the site of extensive boating and marina activities. The water quality of Garrison Bight is currently degraded in comparison to ambient conditions and offshore/unconfined water. In sum, the evidence established that proposed surface water management system meets or exceeds the current permit criteria. Consequently, the water flowing into Garrison Bight from the Site will be significantly less and much cleaner after the proposed surface water management system is installed than it currently is without a designed surface water management system.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered approving the issuance of Surface Water Management General Permit No. 44-01785 in accordance with the Notice of Intent dated September 29, 1992 and the additional conditions noted in this Recommended Order. DONE AND ENTERED this 14th day of May, 1993, at Tallahassee, Florida. J. STEPHEN MENTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 14th day of May, 1993.
Findings Of Fact Petitioner SFWMD is a public corporation of Florida. It is charged with the responsibility of issuing permits and enforcing orders relating to surface water management within its jurisdictional boundaries. Respondents Hubschman, as trustees, have full rights of ownership in 1,280 contiguous acres located in Sections 17 and 20, Township 47 South, Range 26 East, Lee County, Florida. These lands are known as Bonita Farms I and II. They are located within the jurisdictional boundaries of SFWMD. In their pre- developed state, these lands could generally be categorized as marsh and wetlands with cypress forest and some uplands in the northern half of the project area. After deciding to develop the acreage for use as pasture and farmland for small vegetable crops, Respondents Hubschman applied for a surface water management permit from SFWMD. The purpose of the permit was to allow the construction and operation of a water management system that would serve both farms. A system was designed to drain water off both parcels through a 62-acre retention area into a natural slough system which runs water into Kehl Canal. In order to create the system, the Respondents Hubschman had the following facilities designed for the site: internal ditches, dikes, pumps, a retention area and control structures. On April 15, 1982, SFWMD issued Surface Water Management Permit No. 36- 00315-S, and Respondents Hubschman were allowed to proceed with their proposed construction plan. A modification to the permit was issued on April 14, 1983. The retention area was enlarged from 62 acres to 88 acres by relocating the perimeter dike. The outfall structure was revised in that the two pumps and the weir were to be replaced by three 18" CMP culverts that would discharge the drained water by gravity flow from the retention area through the slough into Kehl Canal. The duration of the construction phase of its permit was a three-year period, unless the construction of the permitted project discharge structure or equivalent had been completed prior to that date. After the close of the three-year period, there was a dispute between the Respondents and SFWMD as to whether the permit had expired. The controversy was resolved through a compromise agreement. An application for the reissuance of Permit No. 36-00315-S was filed on October 13, 1986. Instead of reissuing Permit No. 36-00315-S, as requested by Respondents Hubschman, SFWMD decided to issue a new permit on May 14, 1987. As part of the processing procedures, SFWMD again reviewed and approved the entire surface water management system designed to serve the 1,280 acres of land proposed by Respondents. Because the additional work proposed for Section 17, the northern section was limited at this stage of development to the selective clearing of additional upland areas to create more improved pasture, the new permit directed attention to Section 20, the southern section of the land. The new permit advised the Respondents that if they wanted to propose additional development to Section 17, they were required to seek a modification of this new permit, Surface Water Management Permit No. 36-00764-S, to include those changes. The Respondents applied for a modification of Permit No. 36-00764-S on July 30, 1987. The proposed modification sought to change the status of the development of Section 17 from improved pasture to small vegetable farmland on 639 acres. The surface water management system plan was modified to drain water in Section 17 to the reservoir on Section 20. The water would be directed via a series of lateral ditches and swales. A six foot high dike and one 27,000 GPM pump were also required. Two additional 18" CMP culverts were required at the discharge facilities to accommodate the increased outflow. The Modification of Permit No. 36-00764-S was approved and issued on June 16, 1988. The original Permit NO. 36-00764-S and its modification are similar to a contract novation because the new permits substituted new obligations between the parties for the old ones under Permit No. 36-00315-S. Based upon this approach to the situation, SFWMD allowed the construction work completed under Permit No. 36-00315-S prior to the Stop Work Order of August 27, 1986, to vest. The completion of the berm around the reservoir in Section 20, as set forth in the letter from Elizabeth D. Ross, attorney for SFWMD, on September 19, 1986, was also allowed to vest. However, if the vested matters were changed in the subsequent permits, they became revisions. The revisions take precedence over the vested matters. Otherwise, completed construction under Permit No. 36- 00764-S as modified, and post Stop Work Order construction remains in effect perpetually for the operation portion of the permit. In order to determine with certainty what was permitted when the Notice of Violation was issued on December 20, 1988, the parties would have to look to the project work actually completed on August 27, 1986, the specific construction approved by SFWMD after that date, the subsequent Surface Water Management Permit No. 36-00764-S issued May 14, 1987, and its Modification issued June 16, 1988. The substantial compliance determination issued by Richard A. Rogers, P.E., Resource Control Department dated September 24, 1987, should also be considered as authorized activity. The Notice of Violation dated December 20, 1988, was issued to Respondent Samuel Hubschman, Trustee. He was advised that recent routine inspections indicate that current on-site activity was in violation of Special Conditions 2,3,4,7,14, 17 & 23 of Permit No. 36-00764-S (issued 5/14/87) and Special Conditions 5,16 & 22 of 36-00315-S (modified 6/16/88). A meeting to resolve these issued was suggested by SFWMD. Respondent Hubschman agreed to attend the meeting through his consultants. Both parties elected to attempt resolution of the Notice of Violation controversy through negotiations in a meeting scheduled for January 5, 1989. To demonstrate their sincerity, the parties agreed not to bring attorneys to the meeting. During the meeting, the parties resolved the controversy by agreeing to the following: SFWMD would no longer consider the project to be in violation of Florida law if the Respondents submitted certain items that would cause SFWMD to issue certain permits and modify others. The Respondents would promptly file an application for a dewatering permit so that the governing board could issue the permit at its March 9, 1989 meeting. The Respondent's contractor would make no field changes in the mitigation or excavation areas without first obtaining appropriate permit modification from SFWMD. Small jockey pumps were to be installed to pump water from the internal water management system into certain cypress and/or mitigation areas for the sole purpose of establishing wetland vegetation within the areas. Respondents were to apply for a modification of Permit No. 36-00764-S, as currently modified, to allow a single phase of mining for the entire affected area. The perimeter dike was to be made structurally adequate. Respondents were to submit an alternative proposal for the disposal of cap rock within ninety days. In the meantime, the contractor could continue to bury the cap rock within the mitigation areas. Both parties demonstrated their reliance on the settlement reached in the meeting by their subsequent actions towards completing and processing the applications for permit modifications and additional permits. Although the noted violations were not cured by these actions, the parties intended to reach a cure or to mitigate for present permit violations through new permit conditions. The preliminary staff review of the Respondents' application for modification of Permit No. 36-00764-S, as currently modified, was completed by March 31, 1989. The following information was requested by SFWMD staff: Revised engineering calculations which reflect that the permitted discharge structure is five 18" CMP culverts. An explanation as to why the 6.3 acre maidencane/juncus marsh designated as a preserve area and the adjacent western preserve area were excavated and otherwise disturbed by project activities. The scrapedown methodology for the replanting of mitigation areas. The Respondents' plans for the area delineated on the plans as pine, which is currently permitted as part of a cypress preservation area. Dike certification and reservoir certification. The above-listed information was required to be returned to the SFWMD within ninety days from the date of the written request. At the close of the ninety days, the information was not received. A second request for a response within thirty days was submitted by SFWMD on August 4, 1989. In September 1989, the Respondents attempted to comply with SFWMD's second request for information. Communications continued in regard to the filed application for modification of Permit No. 36-00764-S, as currently modified, into December 1989. After the thirty days expired for the response to the second request for information dated August 4, 1989, SFWMD filed the Administrative Complaint in these proceedings. After the second request for information, a partial response was received from Respondent Hubschman's consultants. The application continues to go through the review process. It has not yet been deemed complete by SFWMD. As part of the resolution of the Notice of Violation dated December 20, 1988, SFWMD issued permit No. 36-01023-W to Respondent Hubschman for construction dewatering, excavation of an irrigation pond, and water storage at the site. The permit was issued on March 9, 1989. Special condition No. 20 of this permit requires a 200-feet setback from the cypress mitigation area and the irrigation pond being dewatered. The setback is shown on Exhibit 10 of the Bonita Farms Dewatering Application which was made part of the permit. A copy of the permit was attached to the Administrative Complaint. No evidence was submitted by SFWMD regarding alleged violations of Special condition No. 20 which were allegedly observed and documented after the permit was issued, before the filing of the Administrative Complaint Respondent Bob Cadenhead is the contractor hired by Respondents Hubschman to construct the surface water management system. There was no evidence presented to show the connection of another party, Respondent, Cadenhead & Sons Construction, to the project.
Recommendation Based upon the foregoing, it is RECOMMENDED: That Surface Water Management Permit No. 36-00315-S be deemed to have vested as to all construction activity completed under the permit which was not addressed in the subsequent permit issued by SFWMD. The completion of the berm, as set forth in Attorney Ross' September 19, 1986 letter, should also be allowed to vest. That Permit No. 36-00764-S and its later modification be ordered to supercede the prior permit in all matters specifically addressed. That the parties be held to their prior agreements to resolve pending permit violations through the permit modification process. That the alleged dewatering violation in paragraph 19 of the Administrative Complaint be dismissed for lack of evidence. That a specific deadline be set to reasonably complete pending application modifications. That all future enforcement action specifically comply with Rule 40E- 1.612, Florida Administrative Code, and remain separate from any permit or permit modification applications. That the parties create a new, active permit file with current drawings and a specific construction schedule. That the Administrative Complaint and Order filed in these proceedings be dismissed. That future agreements be reduced to writing and signed by the proper parties before they are relied upon by either party.

The Issue The issue to be determined is whether Application No. 090107-1 for Environmental Resource Permit No. 56-03461-P and the Sovereignty Submerged Lands Public Easement for the Crosstown Parkway Extension should be issued as proposed in the notice issued by the South Florida Water Management District.
Findings Of Fact The Parties Petitioner resides in the City of Port St. Lucie, with a primary residence at 6470 Northwest Volusia Drive, Port St. Lucie, Florida. Petitioner frequents the area to be affected by the Proposed Project and uses the established Savannas Preserve State Park Halpatiokee Trail (“Halpatiokee Trail”) for birdwatching and engaging in activities, including lectures and tours, related to native plants found in the vicinity of the Halpatiokee Trail and the Savannas Preserve State Park. Intervenor is a 501(c)(3) corporation with its principal place of business in the City of Port St. Lucie. Intervenor’s standing was not challenged at the final hearing. The City is a Florida municipal corporation and the applicant for the Permit. The District is a water management district created by section 373.069, Florida Statutes. It has the responsibility to conserve, protect, manage, and control water resources within its geographic boundaries. See § 373.016, Fla. Stat. The District has the power and duty to exercise regulatory jurisdiction over activities subject to the Permit pursuant to chapter 373, Part IV, and to apply and implement statewide environmental resource permitting rules, including Florida Administrative Code Chapter 62-330. § 373.4131(2)(a), Fla. Stat. In implementing responsibilities with regard to ERPs, the District has developed and adopted the ERP Applicant’s Handbook - Volume I (“A.H.”) to provide standards and guidance to applicants. § 373.4131(1)(a)9., Fla. Stat. The District also performs staff duties and functions on behalf of the BTIITF related to the review of applications for authorization to use sovereignty submerged lands necessary for an activity regulated under part IV of chapter 373 for which the District has permitting responsibility. § 253.002(1), Fla. Stat. The District has been delegated the authority to take final agency action, without any action by the BTIITF, on applications for authorization to use sovereignty submerged lands for any activity for which the District has permitting responsibility. § 253.002(2), Fla. Stat.; Fla. Admin. Code R. 18-21.0051(2). Background In 1980, the City had a population of approximately 20,000 residents. The City presently has a population of approximately 179,400 residents and is anticipated to reach 225,000 by 2035. The North Fork of the St. Lucie River (“NFSLR”) runs through the City in a general north-south direction. The City is divided by the NFSLR, with roughly two-thirds of the City being west of the NFSLR, and one-third of the City being east of the NFSLR. The NFSLR in the area of the Proposed Project is an Outstanding Florida Water Body and an Aquatic Preserve. The NFSLR within the City is spanned by two bridges linking and providing access to the two sides of the City. The southernmost bridge is the St. Lucie Boulevard Bridge, a six- lane bridge with three lanes in each direction. The northernmost bridge is the Prima Vista Boulevard Bridge, a four- lane bridge with two lanes in each direction. Both of the existing bridges, and intersections around the bridges, currently operate at peak hours with a level of service of “F”, which is the lowest level of service classification assigned by the Florida Department of Transportation. In addition to traffic congestion, the two existing bridges have been deemed to be deficient in matters of public health and safety, including emergency response times and the need for prompt evacuation in the event of a hurricane or a nuclear incident at the nuclear power plant on nearby Hutchinson Island. Planning The City first identified a third east-west crossing of the NFSLR in its 1980 Comprehensive Plan. A third crossing has been included in each revision to the Comprehensive Plan since that time. In January 2009, the City submitted a conceptual permit application for the Crosstown Parkway Extension to the District. The 2009 application included six proposed bridge alignment alternatives, designated as: 1(C); 1(F); 2(A); 2(D); 6(A); and 6(B). In order to evaluate alternatives for the proposed third crossing, the six alternatives were subjected to environmental assessments which included “purpose and need” considerations. The Proposed Project was evaluated by means of a Project Development and Environmental Study, and the City, in cooperation with the Florida Department of Transportation and the Federal Highway Administration, prepared an Environmental Impact Statement (“EIS”) pursuant to the National Environmental Policy Act. The City, along with Federal and state agencies, participated in the Efficient Transportation Decision Making Process (“ETDM”) to evaluate the alternative east-west corridors crossing the NFSLR. As part of the ETDM process, modifications to eliminate or reduce impact were analyzed, including widening the Prima Vista Boulevard and Port St. Lucie Boulevard bridges, construction of a tunnel, and construction of second decks on the existing bridges. For various legitimate reasons, those options were rejected. The EIS considered each of the proposed bridge alignment alternatives. Each of the alternatives would have affected the NFSLR Aquatic Preserve, though in differing degrees. The analysis of the six alternatives in the EIS was performed using three overall categories: socioeconomic; biological environment; and physical environment. Environmental impacts in terms of acreage and wetland functions were considered. The EIS also considered public health, safety, and welfare considerations as socioeconomic impacts of the six alternatives. Alternative 1(C) was ultimately identified as the preferred alternative corridor in the EIS. In February 2014, the City, the Florida Department of Transportation, and the Federal Highway Administration collectively chose Alternative 1(C) as the preferred route for the Crosstown Parkway Extension. The City amended the permit application in 2014 to request authorization for the construction of alternative 1(C). That amended application is the subject of the proposed agency action at issue. Alignment The existing Crosstown Parkway begins at the interchange of Interstate 95 on the west side of the City, and extends east to Manth Lane. The proposed Crosstown Parkway Extension would extend the existing Crosstown Parkway from its current terminus at Manth Lane for a distance of approximately 1.5 miles to the east side of Floresta Drive, then across a 4,000-foot bridge section over the NFSLR, ending at U.S. Highway 1. The proposed bridge is to be slightly north of midway between the existing bridges. The proposed Crosstown Parkway Extension bridge will have three lanes in each direction, with bicycle lanes and multi-use paths. Petitioners contend that Alternative 6(A) should have been selected as the preferred alignment. Alternative 6(A) would impact the NFSLR Aquatic Preserve and wetlands, though to a lesser extent, but would have far greater impacts to residential communities on both sides of the NFSLR. More to the point, the City presented a prima facie case for the selection of Alternative 1(C) that included considerations of traffic flow, ease of evacuations, hospital access, and impacts to residential communities, all of which are “non-environmental safety factors” that are appropriate for consideration. See Fla. Bay Initiative, Inc., et al. v. Dep’t of Transp. and So. Fla. Water Mgmt. Dist., Case No. 95-5525 et seq. (DOAH Apr. 11, 1997; SFWMD June 23, 1997). Although Petitioners demonstrated that Alternative 6(A) would have fewer environmental effects, they failed to produce substantial competent evidence to counter the safety and public interest factors that are to be weighed and balanced in conjunction with the District’s evaluation of the Permit. The Environmental Resource Permit The proposed Crosstown Parkway Extension corridor includes portions of the NFSLR, Evans Creek, the Coral Reef Waterway, and associated floodplains. The Proposed Project area involves approximately 91.53 acres of development associated with the Crosstown Parkway Extension. Permanent in-water impacts include two sets of pilings. The total area of the pilings is 493 square feet, or 0.0113 acres. Construction of the Crosstown Parkway Extension bridge will involve secondary impacts resulting from shading of the water and benthic riverbed from the bridge, and temporary impacts related to construction. The application includes a 2.134 acre sovereignty submerged lands public easement. Approximately 1.44 acres of the Proposed Project will be constructed in, on, or over sovereignty submerged lands within the NFSLR. The difference in acreage is to account for temporary use of sovereignty submerged lands for construction and maintenance purposes. The area of the Proposed Project includes 14.202 acres of land owned by the BTIITF that are managed as part of the Savannas Preserve State Park. Those lands are not submerged. Authority to grant approval to use non-submerged state lands has not been delegated to the District, is not incorporated in the proposed agency action, and is not at issue in this proceeding. The City has applied for an easement for those state-owned lands from the Department of Environmental Protection (“DEP”). Water Quality and Water Quantity From the standpoint of water quantity permit criteria, the Proposed Project meets the discharge rate, design storm, floodplain encroachment, and flood protection criteria set forth in the ERP rules. The Proposed Project is divided into five stormwater basins. The stormwater management facilities are designed and permitted to provide water quality treatment and attenuation, including wet detention and dry retention areas. Stormwater from the bridge itself will not be drained into the waters of the NFSLR, but will be routed to the management facilities for treatment. The Permit authorizes the required water quality treatment volume of 2.5 inches times the percent of impervious area. The City has agreed to provide 50 percent more water quality treatment volume than is required by the permitting criteria. As to temporary impacts, the Permit includes implementation of a pollution prevention plan/turbidity and erosion control plan with additional conditions requiring compliance with water quality criteria during construction of the Proposed Project. By stipulation of the parties, the City has provided reasonable assurances to satisfy applicable water quality criteria pursuant to rule 62-330.301(1), and has provided reasonable assurances of compliance with rule 62-330.301(1). The Proposed Project is located within the watershed of DEP waterbody/WB ID/number 3194, the North St. Lucie Estuary, which has been identified as impaired for dissolved oxygen, nutrients, and fecal coliform. Since the existing ambient water quality of the receiving waters is impaired for nutrients, the City is required, pursuant to rule 62-330.301(2), to implement measures that will result in a net improvement of the water quality in the receiving waters for nutrients. The Stormwater Management Report, sections 3.1.6 and 4.4, demonstrate that the stormwater management system proposed for the Crosstown Parkway Extension will provide greater removal of nutrients, including nitrogen and phosphorus, than currently exists, which will result in a net improvement of water quality. Thus, the City has established, through its prima facie case, that it meets the standards of rule 62-330.301(2). Petitioners failed to prove, by a preponderance of persuasive competent and substantial evidence, that the stormwater management system would be ineffective to remove nutrients as proposed. Natural Resources There are no seagrasses in the NFSLR in the vicinity of the proposed Crosstown Parkway Extension bridge out to the area subject to potential secondary impacts. Although Ms. Scotto speculated as to the existence of polychaete worms in the area, she had no direct knowledge of any benthic resources at the location. Wetlands within the Crosstown Parkway Extension area can generally be described as freshwater marsh, floodplain forest, and mixed wetland hardwoods. In addition, mangroves fringes exist along the edges of the open water bodies. Impacts Direct Impacts The Proposed Project will result in direct impacts to 7.9 acres of wetlands and 1.18 acres of surface waters with additional secondary impacts. The area of submerged lands physically impacted by the Proposed Project is limited to the pilings that support the bridge, which constitute a total of 0.29 acres of direct impacts. Wetland fill impacts of 1.53 acres will occur where the Crosstown Parkway transitions from a bridge to a roadway, to a width of 225 feet within the U.S. Highway 1 right-of-way. The low level of the bridge structure will result in canopy removal within forested wetlands, and shading of vegetation beneath the bridge structure. As a result, it was assumed that all wetlands underneath the bridge impacted by shading of the structure would be directly and fully eliminated. Petitioners assert that the permit application evaluation should have taken into account direct and secondary impacts to threatened plant species listed by the Department of Agriculture and Consumer Services in Florida Administrative Code Rule 5B-40.0055, particularly the rose pogonia and nodding pinweed. However, the District does not have authority to consider such species in the context of an ERP. Secondary Impacts Secondary impacts are not direct impacts of the Proposed Project, but are those adverse effects to the functions of the surrounding wetlands and habitats that would not occur but for the construction of the Proposed Project. Secondary impacts include shading from the Crosstown Parkway Extension bridge, and light and noise that could deter use of the area by fish and wildlife. Secondary impacts to wetlands were assessed in two zones extending outward from the direct impact area. The first zone extends from 0 to 50 feet from the bridge footprint, and the second zone extends from 50 to 250 feet from the bridge footprint. There was no persuasive competent and substantial evidence that the secondary impacts of the Proposed Project would have any measurable impact on surface waters, including temperature and salinity. The City provided reasonable assurance that the secondary impacts that would be caused by the Proposed Project will not cause or contribute to violations of water quality standards, or adversely affect the functions of adjacent wetlands or other surface waters. Although there will be some locally evident impact to the functions of wetlands within the zones of secondary impact, because the City meets the “Opt-Out” provisions discussed below, the City is not required to implement practicable design modifications to reduce or eliminate such impacts. There was no persuasive competent and substantial evidence that the secondary impacts of the Proposed Project would affect the functions of wetlands outside of the zone of secondary impacts. There was no persuasive competent and substantial evidence that the construction, alteration, and reasonably expected uses of the Crosstown Parkway Extension would adversely impact the ecological value of the uplands to aquatic or wetland-dependent listed species for enabling existing nesting or denning by these species. The loss of canopy, including issues of detrital export and functions related to downstream systems, were accounted for in the UMAM calculations for quantifying the functional loss of resource values resulting from the Proposed Project. Petitioners stipulated to the UMAM scores related to direct impacts of the Proposed Project. Petitioners disagreed with the UMAM scores related to secondary impacts because they were not “considered for the impacts to those [Department of Agriculture and Consumer Services]-listed threatened and endangered plants.” The ERP permitting criteria take into account a comprehensive list of invertebrates, fish, amphibians, reptiles, birds, and mammals that are to be considered in the evaluation of secondary impacts that may result from a project. See A.H. Table 10.2.7-1. The City demonstrated, and Mr. Braun acknowledged, that the permitting standards do not list plants as a matter for consideration, either generically or by species. The suggestion that the evaluation of ecological values must include, by implication, species of plants is not accepted.3/ Mr. Braun also testified that the only issues in dispute regarding the quantification and mitigation of secondary impacts were those pertaining to the headwaters of Hogpen Slough. It was his opinion that the collection and treatment of stormwater from the bridge and road in the permitted stormwater basins will divert and interrupt sheet flow that currently flows from U.S. Highway 1 and undeveloped property to the north into the Hogpen Slough drainage area, and that such effects will alter the salinity envelope in Evans Creek and impact the fishery nursery in the area. However, Mr. Braun admitted that “there has been no modeling that would show how the effect of the changes in the water, how they will be effected by the project.” The basic thrust of Mr. Braun’s testimony was best characterized by the following exchange: Mr. Fumero: You don’t have any analysis to show that what's currently contemplated will result in a salinity imbalance? Your point is that the Applicant should demonstrate, should provide some analysis showing that it will not, correct? Mr. Braun: That's correct.[4/] In response to Petitioners’ concerns with the impacts to Hogpen Slough, the City demonstrated that the Hogpen Slough drainage basin encompasses an area of almost 700 acres, and extends for a mile and a-half to two miles east of the area discussed by Mr. Braun. Upon construction of the Proposed Project, the areas that currently drain to Hogpen Slough will continue to drain to Hogpen Slough, with enhanced water quality treatment and attenuation for the additional impervious area created by the road widening at the intersection with U.S. Highway 1. Thus, the Proposed Project will have a de minimis, if any, effect on the overall quantity of water draining from the Hogpen Slough drainage basin to Hogpen Slough, with the stormwater from the Proposed Project itself being subject to an enhanced degree of water quality treatment. Under the burden of proof applicable to this proceeding, as discussed in the Conclusions of Law herein, Mr. Braun’s concern as to the effect of the Proposed Project on Hogpen Slough, without more, is insufficient to support a finding as to any adverse secondary impacts. Cumulative Impacts The Proposed Project is considered not to have unacceptable cumulative impacts if mitigation offsets adverse impacts within the same basin where the impacts occur. As set forth herein, the proposed mitigation is located within the same basin as the impacts from the Proposed Project. Mitigation The City proposes to provide both on-site and off-site mitigation to offset impacts of the Proposed Project. The City has proposed proprietary mitigation for the easement to cross state lands and regulatory mitigation to compensate for impacts to natural resources. The ecological values of the areas affected by the Proposed Project’s direct, secondary, and temporary impacts to freshwater wetlands and surface waters, and the mitigation needed to offset those impacts, was determined using UMAM. UMAM is authorized by statute and adopted by rule. The undersigned accepts UMAM as an accurate and representative measure of the impacts of the Proposed Project. In order to calculate UMAM functional loss scores, and thereby the mitigation necessary to offset impacts, all areas under the Crosstown Parkway Extension bridge were accounted for as though they were to be filled in their entirety, with 100 percent functional loss. The loss of canopy was accounted for and included consideration of detrital export and functions related to downstream systems. In calculating the mitigation to be provided, the City developed a fictitious “hybrid corridor” that assumed the worst case scenario impacts of each of the six build alternatives identified in the 2009 application. That hybrid corridor included greater impacts than any single alternative corridor, including the Alternative 1(C) corridor at issue. That hybrid corridor was then used as the basis for the development of the mitigation plan used for the Alternative 1(C) corridor. As such, the mitigation proposed is conservative. Applying the UMAM methodology, it was determined that direct impacts would result in 6.64 functional loss units, secondary impacts would result in 2.47 functional loss units, and temporary impacts would result in 0.27 functional loss units, for a total of 9.38 functional loss units. Platt’s Creek To mitigate for the freshwater wetland and surface water impacts, the City constructed the Platt’s Creek mitigation area as authorized by District Permit No. 56-03199-P. Platt’s Creek, located approximately five miles upstream from the project and adjacent to the NFSLR, was an orange grove containing upland habitat and a retention pond. The Platt's Creek project, a joint mitigation area with St. Lucie County, is designed to restore and create hydric hammock, floodplain forest, and freshwater marsh. The mitigation at Platt’s Creek involves the same habitats that are being impacted by the project. Although Platt’s Creek is not located in the NFSLR Aquatic Preserve, it is located upstream of the Proposed Project, within the same basin as the Proposed Project’s impacts, and will provide downstream benefits to the Aquatic Preserve. The Platt's Creek project also provides a regional benefit to the NFSLR by improving water quality. The UMAM calculation established that 9.38 mitigation units would be required to offset the functional loss from all of the Proposed Project impacts. The City dedicated 11.25 functional units from the Platt’s Creek mitigation area to offset the impacts, which is in excess of the requirement. The City has completed construction and planting at Platt’s Creek, and is now monitoring success of the completed mitigation work. Pursuant to the Permit, St. Lucie County is responsible for long-term operation and maintenance of the Platt’s Creek mitigation area. Bear Point As mitigation to offset direct, secondary and temporary mangrove impacts, the City purchased mitigation credits from Bear Point Mitigation Bank located in the Indian River Lagoon. Bear Point provides the same type of mangrove habitat as that affected by the Proposed Project. Using the modified Wetland Rapid Assessment Procedure, which was the method used to determine functional units when the Bear Point Mitigation Bank was created, it was determined that 0.26 functional units would be required to offset the worst case hybrid corridor mangrove impacts applied to the Proposed Project. The City purchased 0.50 functional units from the Bear Point Mitigation Bank to offset the 0.26 acres of functional loss, which is in excess of the requirement. The Proposed Project is in the Mitigation Service Area for the Bear Point Mitigation Bank. The proposed mitigation is within the same basin as the Proposed Project’s impacts. Mitigation Conclusion The City established, by a preponderance of competent substantial evidence, that the mitigation provided was sufficient to offset the environmental impacts. Petitioners failed to counter the City’s case. Mr. Braun’s concerns with the proposed mitigation were primarily directed to its failure to account for impacts to plants species as discussed herein. Ms. Scotto expressed no opinion as to whether the mitigation provided meets the ERP standards, whether the mitigation provided meets the standards for proprietary authorization, or whether the mitigation is consistent with the NFSLR Aquatic Preserve Management Plan. She did not review mitigation for secondary impacts. Ms. Goldberg, noting the extent of the proprietary mitigation provided, testified that mitigation should not be a “Christmas present” for agencies. She also noted that Platt’s Creek does not match the maturity and diversity of the impact areas. However, she did not dispute the UMAM scores that formed the basis for the mitigation. Elimination or Reduction of Impacts The City reduced the width of the main section of the bridge from 143 feet to 103 feet, resulting in a 3.27 acre reduction of impacts, an approximate 30-percent reduction. The evidence was convincing that the bridge could not be further reduced in width without compromising safety and functionality. The City proposed construction methods, including the use of top-down construction or construction by use of temporary pile-supported structures, designed to reduce temporary construction-related impacts. The City has committed to the installation of specialized light fixtures that direct light onto the pavement only, which will reduce light trespass on adjacent habitats. Impacts were eliminated and reduced through the location and design of the stormwater ponds as described in the Permit. No evidence was adduced to counter the prima facie case on that issue. Although Alternative 1(C) had greater environmental impacts than other build alternatives, the City demonstrated by a preponderance of the competent substantial evidence that non- environmental safety factors, including traffic flow, ease of evacuations, hospital access, and impacts to residential communities, precluded further efforts to avoid impacts through the selection of a different corridor. Opt-Out Provision A.H. section 10.2.1.2(b) provides that: The Agency will not require the applicant to implement practicable design modifications to reduce or eliminate impacts when: * * * b. The applicant proposes mitigation that implements all or part of a plan that provides regional ecological value and that provides greater long term ecological value than the area of wetland or other surface water to be adversely affected. Although the areas impacted by the proposed Crosstown Parkway Extension bridge are of high quality, the combination of using the Platt’s Creek Mitigation Area, the Bear Point Mitigation Bank, and the NFSLR Aquatic Preserve Management Plan Projects, provides regional ecological value and greater long- term ecological value than the areas affected. Based thereon, the City was not required to implement practicable design modifications to reduce or eliminate impacts of the Proposed Project though, as indicated herein, it did so. Public Interest Balancing Test Portions of the Proposed Project are within Outstanding Florida Waters. Therefore, the City must provide reasonable assurances that the Proposed Project is clearly in the public interest, as described by the balancing test set forth in section 373.414(1)(a), rule 62-330.302(1)(a), and A.H. sections 10.2.3 through 10.2.3.7. To determine whether a regulated activity located in, on, or over wetlands or other surface waters is in the public interest, the following criteria must be considered and balanced: whether the regulated activity will adversely affect the public health, safety, or welfare or the property of others; whether the regulated activity will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; whether the regulated activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; whether the regulated activity will be of a temporary or permanent nature; whether the regulated activity will adversely affect or will enhance significant historical and archaeological resources; and the current condition and relative value of functions being performed by areas affected by the proposed regulated activity. Public Health, Safety, or Welfare or the Property of Others A.H. section 10.2.3.1 establishes four criteria to be balanced in order to determine if regulated activities will adversely affect the public health, safety, or welfare or the property of others. The evidence in this case failed to demonstrate that impacts resulting from the Proposed Project would affect waters subject to a shellfish harvesting classification (A.H. section 10.2.3.1(b)), would cause or alleviate flooding on the property of others (A.H. section 10.2.3.1(c)), or would result in environmental impacts to the property of others (A.H. section 10.2.3.1(d)). A.H. section 10.2.3.1(a) requires an evaluation of hazards or improvements to public health or safety. The Crosstown Parkway Extension is calculated to relieve traffic and access problems that have earned the existing roadway infrastructure linking the east and west sides of the City a service level of “F”. By so doing, the Crosstown Parkway Extension is designed to improve emergency response times and evacuation times. The proposed Crosstown Parkway Extension corridor involves the fewest overall impacts to residences, communities, and businesses. Petitioners assert that the Crosstown Parkway Extension will create health issues from vehicle emissions, and adverse effects to wildlife and habitat from light pollution. Those alleged impacts would apply to all of the build alternatives, including Petitioners’ preferred Alternative 6(A). Furthermore, Petitioners failed to provide any quantification of either the amount or effect of any such impacts. Finally, as to the alleged light pollution, the City incorporated design modifications to the bridge lighting system to reduce such impacts. There was insufficient evidence to support a finding that the Crosstown Parkway Extension will, on balance, adversely affect public health or safety. Although more directly relevant to the sovereignty submerged lands easement, the water quality enhancement projects, including the installation of baffle boxes, reestablishment of oxbows, and dredging of unsuitable sediments in Evans Creek, will maintain and improve water quality in the NFSLR and, as a whole, result in an improvement to the water quality of the NFSLR. Thus, reasonable assurance has been provided that the Crosstown Parkway Extension will not adversely affect public health, safety, or welfare or the property of others. Conservation of Fish and Wildlife The Endangered Species Biological Assessment Report submitted as part of the ERP application was comprehensive in its scope, assessing each of the bridge alternatives. The Report concluded that the Proposed Project would have no effect on any federally-listed plant species, “may affect but [was] not likely to adversely affect” listed species, including the smalltooth sawfish, eastern indigo snake, wood stork, and manatee, and would have no effect on any other federally-listed species. The area of the Proposed Project includes no designated critical habitat. The report further concluded that each of the build alternatives, including the Proposed Project, could affect several state-listed plant and animal species, but that the Proposed Project would affect no threatened or endangered species. As to those state-listed species, the Report concluded that efforts to avoid and minimize impacts to species and their habitats had been implemented, and that a mitigation plan had been developed to compensate for unavoidable impacts to wetlands and fish habitat. The Report, which is part of the ERP application, and is, by law, part of the City’s prima facie case, is accepted. The City agreed to perform surveys for protected species and implement measures designed to protect those species from direct project effects as described by the Fish and Wildlife Conservation Commission. There was insufficient evidence to demonstrate that the agreed-upon surveys and protective measures would be ineffective in preventing adverse impacts to the wildlife species of concern. Furthermore, the City incorporated design features and construction methodologies to reduce and eliminate impacts, and provided mitigation to replace functions provided to these species affected as a result of the project. More mitigation to provide habitat and improve water quality within or adjacent to the NFSLR and the Aquatic Preserve has been provided than was required. The mitigation provides regional ecological value and greater long-term ecological value than the wetlands to be impacted. There was insufficient evidence to support a finding that the Crosstown Parkway Extension will result in adverse impacts to the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters, or adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats. Petitioners assert that various plant species listed by the Florida Department of Agriculture and Consumer Services will be impacted by the Proposed Project. As set forth previously, the plant species of concern to Petitioners are not species defined in the A.H., and are not species that are subject to consideration in the decision to issue or deny an ERP. As set forth in paragraphs 54 and 55 above, Petitioners also assert that the alteration of the inputs to Hogpen Creek would affect the salinity regime in the Evans Creek receiving waters, thereby adversely affecting fishery nursery areas. Petitioners’ argument was made without information on the volume of water to be discharged over what period of time, without information as to the size of the Hogpen Slough watershed, without information as to the stormwater system design, and without modeling that would show how the waters would be affected by the Proposed Project. In sum, the evidence as to adverse impacts to Hogpen Slough, and resultant effects on the conservation of fish and wildlife, was made without evaluation, and was entirely speculative. The City demonstrated that areas that currently drain to Hogpen Slough will continue to drain to Hogpen Slough, with enhanced water quality treatment, and with attenuation for the additional impervious area created by the road widening at the intersection with U.S. Highway 1. Thus, the preponderance of the evidence indicates that post-construction discharges of water to Hogpen Slough will offer greater benefits to the conservation of fish and wildlife than current discharges. The City has demonstrated, by a preponderance of competent substantial evidence, that the proposed Project will not adversely affect the conservation of fish and wildlife, or their habitats. Navigation, Flow of Water, or Erosion or Shoaling The Proposed Project will not prevent fishing, boating, or other forms of recreation in the NFSLR. A bridge hydraulic analysis demonstrates that the Proposed Project will not cause impacts to water levels, flow, or velocity of the NFSLR or other water bodies. Navigation will not be adversely impacted as the bridge span will be at least as high as other bridges on the NFSLR. The bridge will meet Coast Guard minimum clearances, and Coast Guard-required aids to navigation will be included. Navigation by canoes and kayaks will be improved because of the dredging of the unsuitable sediments and the placement of a new and more accessible canoe launch. The Permit requires the implementation of best management practices to prevent erosion and sedimentation during construction. The City has demonstrated, by a preponderance of competent substantial evidence, that the Crosstown Parkway Extension bridge would cause no adverse effect on navigation or the flow of water, or harmful erosion or shoaling. Fishing or Recreational Values or Marine Productivity The Proposed Project is expected to have no effect on fishing, sport or commercial fisheries, or marine productivity. Although recreational values and fishing may be affected during construction, such impacts are temporary. The long-term effects of the Proposed Project, which include those direct and secondary impacts caused by shading of the vegetative and benthic resources under and adjacent to the Crosstown Parkway Extension bridge, are offset by mitigation including the reconnection of oxbows, which is designed to improve water quality and provide habitat that was previously isolated, and sediment dredging at Evans Creek, which will also improve water quality, fish habitat, and recreational values. The new Americans with Disabilities Act (“ADA”)- compliant canoe/kayak launch will allow for improved and more accessible recreational use. As has been discussed at length herein, the evidence was insufficient to support a finding that the Proposed Project will be reasonably expected to eliminate or degrade fish nursery habitat, change ambient water temperature, change the normal salinity regime, significantly reduce detrital export, change nutrient levels, or otherwise have any adverse effects on populations of native aquatic organisms. Rather, with the mitigation proposed in terms of land acquisition, access enhancement, sediment removal and re-establishment of oxbows, water quality treatment projects, and the stormwater treatment and attenuation being provided, the City established that the Proposed Project would have no measurable adverse impact on fishing, recreational values, or marine productivity. There is no doubt that Petitioner’s enjoyment of the Halpatiokee Trail will be compromised. However, alternative, though more publically accessible areas for walking and canoeing will be provided. Petitioner was critical of the fact that the alternative areas would not be as wild and undeveloped as the existing trails and was particularly critical of the Savannas County Park Trail mitigation, since it is paved to provide access for handicapped nature lovers. This is, however, a balancing test. Based on the record as a whole, there was insufficient evidence to support a finding that the Proposed Project will, on balance, have an adverse effect on fishing or recreational values and marine productivity. Temporary or Permanent Nature The Proposed Project is of a permanent nature. Temporary impacts will occur during construction, but are considered less harmful than the permanent impacts as the temporary impact areas will eventually recover. Although there will be permanent habitat loss, such loss will be offset through mitigation. Historical and Archaeological Resources There was no evidence of significant historical or archaeological resources on or near the Proposed Project. Current Condition and Relative Value of Functions The current condition and relative value of functions is high, as demonstrated by the UMAM scores. This value is due to the location in the NFSLR Aquatic Preserve and state park, connectivity to other wetlands and surface waters, and utilization by fish and wildlife. To offset impacts to the current condition and relative value of functions being performed by areas affected by the Proposed Project, the City provided mitigation in excess of the rule requirements, including the purchase and enhancement of additional lands, and the construction of various types of water quality improvement projects. The mitigation projects and goals are described in the Aquatic Preserve Mitigation Plan. Public Interest Balancing Test - Conclusion The City has proven, by a preponderance of the competent substantial evidence adduced in this proceeding, that, upon balancing the impacts of the Proposed Project with its benefits, the activities authorized by the Permit will be clearly in the public interest. Sovereignty Submerged Lands The City requested an easement over 2.134 acres of sovereignty submerged lands. Approximately 1.44 acres of the 91.53-acre project will be constructed in, on, or over sovereignty submerged land. Permanent in-water impacts consist of two sets of piles to be installed in the Coral Reef Waterway, the NFSLR, and Evans Creek, with a total fill area within the sovereignty submerged lands of 492 square feet or 0.0113 acres. The submerged lands public easement is 157 feet wide, greater than the reduced 104-foot width of the Crosstown Parkway Extension bridge. The area of the easement in excess of the 1.44 acres over which the bridge will pass is to accommodate temporary construction and maintenance activities. Aquatic Preserve The area within the sovereignty submerged lands easement is in the NFSLR Aquatic Preserve. In order to obtain an easement in an aquatic preserve, the City is required to demonstrate that the benefits exceed the costs, and that the Proposed Project is consistent with the NFSLR Aquatic Preserve Management Plan. Consistency with the NFSLR Aquatic Preserve Management Plan is a component of the public interest assessment required by rule 18-20.004(2)(a)(3). Proprietary mitigation was proposed for recreation areas, water quality and quantity, wetlands, wildlife and habitat, floodplain social considerations, and relocations. Proprietary mitigation consistent with the NFSLR Aquatic Preserve Management Plan includes: the installation of baffle boxes within five waterways that discharge into the aquatic preserve. Baffle boxes are designed to slow the flow of water from upland and developed areas, allowing sediment to fall out before the water is discharged to the NFSLR. They are a proven and effective means of improving water quality in a receiving water body; the removal of muck and sediment from Evan’s Creek. The removal of such materials is designed to improve water quality, navigation, and habitat in Evans Creek; the construction of a new, ADA-accessible canoe/kayak launch to replace the current Halpatiokee launch that will be displaced by the Crosstown Parkway Extension, the creation of the ADA-compliant Savannas Recreation Area Trail between Savanna Road and Midway Road, and the improvement of the Savannas Preserve State Park Education Center. The Halpatiokee canoe/kayak launch was slated for closure by the DEP under any of the build alternatives. ADA-accessibility for the canoe/kayak launch and recreation trail, along with improved canoe/kayak launch parking, will enhance public access to the NFSLR Aquatic Preserve and Savannas Preserve State Park5/; purchase and conveyance to the BTIITF of approximately 110 acres, including wetlands and uplands adjacent to the Aquatic Preserve at the Evans Creek, Crowberry, Brywood, Emerson, Highpoint, and Riverwalk sites. Acquisition also includes the Green River parcel in the Savannas Preserve State Park. Each of those sites was identified as priority acquisitions in the NFSLR Aquatic Preserve Management Plan or by the DEP. The conveyances also include an obligation for the City to remove exotic vegetation from the parcels over a period of five years; and oxbow reconnection and removal of accumulated sediments at Site 5 West and Riverplace Upstream, adjacent to the Aquatic Preserve, designed to improve water quality and habitat. Cost/Benefit Analysis Costs related to the 2.134-acre easement include reduced habitat at the bridge location, shading of the water column and areas of herbaceous and forested wetlands, including mangroves, pre-emption of public use, some of which is temporary and some of which due to the loss of functional use of the Halpatiokee Trail under the bridge, and reduced aesthetics. Those costs, except for the Halpatiokee Trail impacts, would be evident to varying degrees at each of the proposed build alternative routes. The City demonstrated that the Crosstown Parkway Extension is a public necessity for which no other reasonable alternative exists. The Crosstown Parkway Extension provides the most efficient means of addressing current traffic congestion, the severe traffic congestion anticipated in the future, and other access and evacuation issues described herein, with the least overall impact to the public. The Crosstown Parkway Extension will not involve dredging or filling in the Aquatic Preserve. Although there will be pilings in the Aquatic Preserve, pilings are not “fill” pursuant to rule 18-20.003(27). The DEP and the City entered into a Memorandum of Understanding (“MOU”) that identifies projects that the City committed to undertake, and lands that the City committed to convey to state ownership to provide for proprietary and sovereignty submerged lands mitigation. The MOU projects are consistent with the approved NFSLR Aquatic Preserve Management Plan. Consistency with an adopted management plan is given great weight when determining whether the project is in the public interest. As set forth above, benefits of the Proposed Project to the Aquatic Preserve include enhanced public access, improved and enhanced water quality, and enhancement and restoration of natural habitats and functions. The City also proposes to convey approximately 110 acres to the BTIITF. The City has proven, by a preponderance of the competent substantial evidence adduced in this proceeding, that, upon balancing, the social, economic, and environmental benefits associated with the Proposed Project, including the extensive proprietary mitigation being provided, far exceed the costs of the 2.134-acre submerged lands easement. Findings of Fact - Conclusion Based on the foregoing Findings of Fact, and as supported by a preponderance of the competent, substantial, and credible evidence, the standards and conditions for issuance of the Permit as set forth herein have been satisfied.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law set forth herein, it is RECOMMENDED that the South Florida Water Management District enter a final order approving the issuance of Environmental Resource Permit and Sovereignty Submerged Lands Public Easement, Permit No. 56-03461-P, to The City of Port St. Lucie, on the terms and conditions set forth in the Notice of Consolidated Intent to Issue and Staff Report, as modified, and the complete Application for Environmental Resource Permit. Said approval shall not be construed as relieving The City of Port St. Lucie from obtaining an upland easement for the 14.202 acres of non-submerged state-owned land required for the Proposed Project. DONE AND ENTERED this 8th day of November, 2016, in Tallahassee, Leon County, Florida. S E. GARY EARLY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 8th day of November, 2016. 1/ T.162:22-181:19.
The Issue The issue to be determined is whether the applicants, Far Niente Stables II, LLC; Polo Field One, LLC; Stadium North, LLC; and Stadium South, LLC, are entitled to issuance of a permit by the South Florida Water Management District (SFWMD or District) for the modification of a surface-water management system to serve the 24.1-acre World Dressage Complex in Wellington, Florida.
Findings Of Fact The Parties Petitioners Charles Jacobs and Kimberly Jacobs are the owners of a residence at 2730 Polo Island Drive, Unit A-104, Wellington, Florida. The residence is used by the Jacobs on an annual basis, generally between October and Easter, which corresponds to the equestrian show season in Florida. Petitioners maintain their permanent address in Massachusetts. The District is a public corporation, existing by virtue of chapter 25270, Laws of Florida 1949. The District is responsible for administering chapter 373, Florida Statutes, and title 40E, Florida Administrative Code, within its geographic boundaries. The District’s statutory duties include the regulation and management of water resources, including water quality and water supply, and the issuance of environmental resource permits. The Applicants, Far Niente Stables II, LLC; Polo Field One, LLC; Stadium North, LLC; and Stadium South, LLC, are Florida limited-liability companies with business operations in Wellington, Florida. The Applicants are the owners of four parcels of property, parts of which comprise the complete 24.1- acre proposed Complex, and upon which the surface-water management facilities that are the subject of the Permit are to be constructed. Contiguous holdings of the four Applicants in the area consist of approximately 35 additional acres, primarily to the north and west of the Complex. Acme Improvement District The Acme Improvement District was created in the 1950s as a special drainage district. At the time of its creation, the Acme Improvement District encompassed 18,200 acres of land. As a result of additions over the years, the Acme Improvement District currently consists of approximately 20,000 acres of land that constitutes the Village of Wellington, and includes the Complex property. On March 16, 1978, the District issued a Surface Water Management Permit, No. 50-00548-S, for the Acme Improvement District (1978 Acme Permit) that authorized the construction and operation of a surface-water management system, and established design guidelines for subsequent work as development occurred in the Acme Improvement District. The total area covered by the 1978 Acme Permit was divided into basins, with the dividing line being, generally, Pierson Road. Basin A was designed so that its interconnected canals and drainage features would discharge to the north into the C-51 Canal, while Basin B was designed so that its interconnected canals and drainage features would discharge to the south into the C-40 Borrow Canal. Water management activities taking place within the boundaries of the Acme Improvement District are done through modifications to the 1978 Acme Permit. Over the years, there have been literally hundreds of modifications to that permit. The Property The Complex property is in Basin A of the Acme Improvement District, as is the property owned by Petitioners. Prior to January 1978, the property that is proposed for the Complex consisted of farm fields. At some time between January, 1978 and December 18, 1979, a very narrow body of water was dredged from abandoned farm fields to create what has been referred to in the course of this proceeding as “Moose Lake.” During that same period, Polo Island was created, and property to the east and west of Polo Island was filled and graded to create polo fields. Polo Island is surrounded by Moose Lake. When it was created, Polo Island was filled to a higher elevation than the adjacent polo fields to give the residents a view of the polo matches. Petitioners’ residence has a finished floor elevation of 18.38 feet NGVD, which is more than three-quarters of a foot above the 100-year flood elevation of 17.5 feet NGVD established for Basin A. The Complex and Petitioner’s residence both front on Moose Lake. There are no physical barriers that separate that part of the Moose Lake fronting Petitioners’ residence from that part of Moose Lake into which the Complex’s surface-water management system is designed to discharge. Moose Lake discharges into canals that are part of the C-51 Basin drainage system. Discharges occur through an outfall at the south end of Moose Lake that directs water into the C-23 canal, and through an outfall at the east end of Moose Lake that directs water into the C-6 canal. There are no wetlands or surface water bodies located on the Complex property. 2005-2007 Basin Study and 2007 Acme Permit Material changes in the Acme Drainage District since 1978 affected the assumptions upon which the 1978 ACME Permit was issued. The material changes that occurred over the years formed the rationale for a series of detailed basin studies performed from 2005 through 2007. The basin studies, undertaken by the District and the Village of Wellington, analyzed and modeled the areas encompassed by the 1978 Acme Permit in light of existing improvements within the Acme Improvement District. The changes to Basin A and Basin B land uses identified by the basin studies became the new baseline conditions upon which the District and the Village of Wellington established criteria for developing and redeveloping property in the Wellington area, and resulted in the development of updated information and assumptions to be used in the ERP program. On November 15, 2007, as a result of the basin studies, the District accepted the new criteria and issued a modification of the standards established by the 1978 Acme Permit (2007 Acme Permit). For purposes relevant to this proceeding, the 2007 Acme Permit approved the implementation of the new Permit Criteria and Best Management Practices Manual for Works in the Village of Wellington.1/ The language of the 2007 Acme Permit is somewhat ambiguous, and portions could be read in isolation to apply only to land in Basin B of the Acme Improvement District. Mr. Waterhouse testified that the language of the permit tended to focus on Basin B because it contained significant tracts of undeveloped property, the land in Basin A having been essentially built-out. However, he stated that it was the District’s intent that the Permit Criteria and Best Management Practices Manual for Works in the Village of Wellington adopted by the 2007 Acme Permit was to apply to all development and redevelopment in the Acme Improvement District, and that the District had applied the permit in that manner since its issuance. Mr. Waterhouse’s testimony was credible, reflects the District’s intent and application of the permit, and is accepted. The Proposed Complex The Complex is proposed for construction on the two polo fields to the west of Polo Island, and properties immediately adjacent and contiguous thereto.2/ The Complex is designed to consist of a large covered arena; several open-air equestrian arenas; four 96-stall stables, with associated covered manure bins and covered horse washing facilities, located between the stables; an event tent; a raised concrete vendor deck for spectators, exhibitors, and vendors that encircles three or four of the rings; and various paved access roads, parking areas, and support structures. Of the 96 stalls per stable, twenty percent would reasonably be used for storing tack, feed, and similar items. The surface-water management system that is the subject of the application consists of inlets and catch basins, underground drainage structures, dry detention areas, swales for conveying overland flows, and exfiltration trenches for treatment of water prior to its discharge at three outfall points to Moose Lake. The horse-washing facilities are designed to tie into the Village of Wellington’s sanitary sewer system, by-passing the surface water management system. The Permit Application On May 18, 2011, two of the Applicants, Far Niente Stables II, LLC, and Polo Field One, LLC, applied for a modification to the 1978 Acme Improvement District permit to construct a surface-water management system to serve the proposed Complex. At the time of the initial application, the proposed Complex encompassed 20 acres. There were no permitted surface water management facilities within its boundaries. The Complex application included, along with structural elements, the implementation of Best Management Practices (BMPs) for handling manure, horse-wash water, and other equestrian waste on the property. Properties adjacent to the Complex, and under common ownership of one or more of the Applicants, have been routinely used for equestrian events, including temporary support activities for events on the Complex property. For example, properties to the north of the Complex owned by Far Niente Stables II, LLC, and Polo Field One, LLC, have been used for show-jumping events, derby events, and grand prix competitions, as well as parking and warm-up areas for derby events and for dressage events at the Complex. Except for an earthen mound associated with the derby and grand prix field north of the Complex, there has been no development on those adjacent properties, and no requirement for a stormwater management system to serve those properties. Thus, the adjacent properties are not encompassed by the Application. Permit Issuance On November 22, 2011, Permit No. 50-00548-S-203 was issued by the District to Far Niente Stables II, LLC. Polo Field One, LLC, though an applicant, was not identified as a permittee. On January 13, 2012, the District issued a “Correction to Permit No. 50-00548-S-203.” The only change to the Permit issued on November 22, 2011, was the addition of Polo Field One, LLC, as a permittee. On January 25, 2012, the Applicants submitted a request for a letter modification of the Permit to authorize construction of a 1,190-linear foot landscape berm along the eastern property boundary. On February 16, 2012, the District acknowledged the application for the berm modification, and requested additional information regarding an access road and cul-de-sac on the west side of the Complex that extended into property owned by others. On that same date, the Applicants provided additional information, including evidence of ownership, that added Stadium North, LLC and Stadium South, LLC, as permittees. On March 26, 2012, the District issued the proposed modification to Permit No. 50-00548-S-203. On November 15, 2012, the Applicants’ engineer prepared a revised set of plans that added 2.85 acres of property to the Complex. The property, referred to as Basin 5, provided an additional dry detention stormwater storage area. On or shortly after December 3, 2012, the Applicants submitted a final Addendum to Surface Water Management Calculations that accounted for the addition of Basin 5 and other changes to the Permit application that increased the size of the Complex from 20 acres to 24.1 acres. On December 18, 2012, the Applicants submitted final revisions to the BMPs in an Updated BMP Plan. On January 7, 2013, the District issued the final proposed modification to the permit. The modification consisted of the addition of Basin 5, the deletion of a provision of special condition 14 that conflicted with elements of the staff report, the Updated BMP Plan, the recognition of an enforcement proceeding for unauthorized construction of the linear berm and other unauthorized works, and changes to the Permit to conform with additional information submitted by the Applicants. The final permitted surface-water management system consists of inlets and catch basins, underground drainage structures, a 0.64-acre dry detention area, swales for conveying overland flows, and 959-linear feet of exfiltration trench. For purposes of this proceeding, the “Permit” that constitutes the proposed agency action consists of the initial November 22, 2011, Permit; the January 13, 2012, Correction; the March 26, 2012, letter modification; and the January 7, 2013 modification. Post-Permit Activities at the Complex Work began on the Complex on or about November 28, 2011. Work continued until stopped on April 18, 2012, pursuant to a District issued Consent Order and Cease and Desist. As of the date of the final hearing, the majority of the work had been completed. In late August, 2012, the Wellington area was affected by rains associated with Tropical Storm Isaac that exceeded the rainfall totals of a 100-year storm event. Water ponded in places in the Polo Island subdivision. That ponded water was the result of water falling directly on Polo Island, and may have been exacerbated by blockages of Polo Island drainage structures designed to discharge water from Polo Island to Moose Lake. No residences were flooded as a result of the Tropical Storm Isaac rain event. The only flooding issue related to water elevations in Moose Lake was water overflowing the entrance road, which is at a lower elevation. The road remained passable. Road flooding is generally contemplated in the design of stormwater management systems and does not suggest a failure of the applicable system. Permitting Standards Standards applicable to the Permit are contained in Florida Administrative Code Rule 40E-4.301(1)(a)-(k), and in the District’s Basis of Review for Environmental Resource Permit Applications (BOR), which has been adopted by reference in rule 40E-4.091(1)(a). The parties stipulated that the standards in rules 40E-4.301(1)(d),(g) and (h) are not at issue in this proceeding. Permitting Standards - Water Quantity Those provisions of rule 40E-4.301 that remain at issue in this proceeding, and that pertain to water quantity, are as follows: In order to obtain a standard general, individual, or conceptual approval permit under this chapter . . . an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal or abandonment of a surface water management system: Will not cause adverse water quantity impacts to receiving waters and adjacent lands; Will not cause adverse flooding to on- site or off-site property; Will not cause adverse impacts to existing surface water storage and conveyance capabilities. In addition to the preceding rules, section 6.6 of the BOR, entitled “Flood Plain Encroachment,” provides that “[n]o net encroachment into the floodplain, between the average wet season water table and that encompassed by the 100-year event, which will adversely affect the existing rights of others, will be allowed.” Section 6.7 of the BOR, entitled “Historic Basin Storage,” provides that “[p]rovision must be made to replace or otherwise mitigate the loss of historic basin storage provided by the project site.” The purpose of a pre-development versus post- development analysis is to ensure that, after development of a parcel of property, the property is capable of holding a volume of stormwater on-site that is the same or greater than that held in its pre-development condition. On-site storage includes surface storage and soil storage. Surface Storage Surface storage is calculated by determining the quantity of water stored on the surface of the site. Mr. Hall found no material errors in the Applicants’ calculations regarding surface storage. His concern was that the permitted surface storage, including the dry detention area added to the plans in December 2012, would not provide compensating water storage to account for the deficiencies he found in the soil storage calculations discussed herein. Based on the foregoing, the Applicants’ surface storage calculations are found to accurately assess the volume of stormwater that can be stored on the property without discharge to Moose Lake. Soil Storage Soil storage is water that is held between soil particles. Soil storage calculations take into consideration the soil type(s) and site-specific soil characteristics, including compaction. Soils on the Complex property consist of depressional soils. Such soils are less capable of storage than are sandier coastal soils. When compacted, the storage capacity of depressional soils is further reduced. The Applicants’ calculations indicated post- development storage on the Complex property to be 25.04 acre/feet. Mr. Hall’s post-development storage calculation of 25.03 acre/feet was substantively identical.3/ Thus, the evidence demonstrates the accuracy of Applicants’ post- development stormwater storage calculations. The Applicants’ calculations showed pre-development combined surface and soil storage capacity on the Property of 24.84 acre/feet. Mr. Hall calculated pre-development combined surface and soil storage, based upon presumed property conditions existing on March 16, 1978, of 35.12 acre/feet. Based on the foregoing, Mr. Hall concluded that the post-development storage capacity of the Complex had a deficit of 10.09 acre/feet of water as compared to the pre-development storage capacity of the Property, which he attributed to a deficiency in soil storage. The gist of Mr. Hall’s disagreement centered on the Applicants’ failure to consider the Complex’s pre-development condition as being farm fields, as they were at the time of issuance of the 1978 Acme Permit, and on the Applicants’ application of the 25-percent compaction rate for soils on the former polo fields. As applied to this case, the pre-development condition of the Complex as polo fields was a reasonable assumption for calculating soil storage, rather than the farm fields that existed in January 1978, and is consistent with the existing land uses identified in the 2005-2007 basin studies and 2007 Acme Permit. Given the use of the Complex property as polo fields, with the attendant filling, grading, rolling, mowing, horse traffic, parking, and other activities that occurred on the property over the years, the conclusion that the soils on the polo fields were compacted, and the application of the 25- percent compaction rate, was a reasonable assumption for calculating soil storage. Applying the Applicants’ assumptions regarding existing land uses for the Complex property, the greater weight of the evidence demonstrates that the proposed surface water management system will provide a total of 25.04-acre feet of combined soil and surface storage compared to pre-development soil and surface storage of 24.84-acre feet. Thus, the proposed Project will result in an increase of soil and surface storage over pre-development conditions, and will not cause or contribute to flooding or other issues related to water quantity.4/ Based on the foregoing, the Applicants have provided reasonable assurances that the proposed surface-water management system will meet standards regarding water quantity established in rule 40E-4.301(1)(a), (b), and (c), and sections 6.6 and 6.7 of the BOR. Permitting Standards - Water Quality Those provisions of rule 40E-4.301 that remain at issue in this proceeding, and that pertain to water quality, are as follows: In order to obtain a standard general, individual, or conceptual approval permit under this chapter . . . an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal or abandonment of a surface water management system: * * * Will not adversely affect the quality of receiving waters such that the water quality standards . . . will be violated; Will not cause adverse secondary impacts to the water resources. Section 373.4142, entitled “[w]ater quality within stormwater treatment systems,” provides, in pertinent part, that: State surface water quality standards applicable to waters of the state . . . shall not apply within a stormwater management system which is designed, constructed, operated, and maintained for stormwater treatment Such inapplicability of state water quality standards shall be limited to that part of the stormwater management system located upstream of a manmade water control structure permitted, or approved under a noticed exemption, to retain or detain stormwater runoff in order to provide treatment of the stormwater . . . . Moose Lake is a component of a stormwater-management system that is located upstream of a manmade water control structure. The Permit application did not include a water quality monitoring plan, nor did the Permit require the Applicants to report on the water quality of Moose Lake. During October and November, 2012, Petitioners performed water quality sampling in Moose Lake in accordance with procedures that were sufficient to demonstrate the accuracy of the results. The sampling showed phosphorus levels in Moose Lake of greater than 50 parts per billion (ppb).5/ That figure, though not a numeric standard applicable to surface waters, was determined to be significant by Petitioners because phosphorus may not exceed 50 ppb at the point at which the C-51 Canal discharges from the Acme Improvement District into the Everglades system. Notwithstanding the levels of phosphorus in Moose Lake, Mr. Swakon admitted that “the calculations that are in the application for water quality treatment are, in fact, met. They’ve satisfied the criteria that are in the book.” In response to the question of whether “[t]he water quality requirements in the Basis of Review . . . the half inch or one inch of runoff, the dry versus wet detention . . . complied with those water quality requirements,” he further testified “[i]t did.” Mr. Swakon expressed his belief that, despite Applicants’ compliance with the standards established for water quality treatment, a stricter standard should apply because the pollutant-loading potential of the Complex, particularly phosphorus and nitrogen from animal waste, is significantly different than a standard project, e.g., a parking lot. No authority for requiring such additional non-rule standards was provided. The evidence demonstrates that the Applicants provided reasonable assurances that all applicable stormwater management system standards that pertain to water treatment and water quality were met. Permitting Standards - Design Features and BMPs Provisions of rule 40E-4.301 that remain at issue in this proceeding, and that constitute more general concerns regarding the design of the Complex, are as follows: In order to obtain a standard general, individual, or conceptual approval permit under this chapter . . . an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal or abandonment of a surface water management system: * * * Will be capable, based on generally accepted engineering and scientific principles, of being performed and of functioning as proposed. Petitioners alleged that certain deficiencies in the Complex design and BMPs compromise the ability of the stormwater management system to be operated and function as proposed. Design Features Petitioners expressed concern that the manure bin, though roofed, had walls that did not extend to the roofline, thus allowing rain to enter. Photographs received in evidence suggest that the walls extend to a height of approximately six feet, with an opening of approximately two feet to the roof line. The plan detail sheet shows a roof overhang, though it was not scaled. Regardless, the slab is graded to the center so that it will collect any water that does enter through the openings. Based on the foregoing, the Applicants have provided reasonable assurances that the manure bins are sufficient to prevent uncontrolled releases of animal waste to the stormwater management system or Moose Lake. Petitioners suggested that the horse-washing facilities, which discharge to a sanitary sewer system rather than to the stormwater management facility, are inadequate for the number of horses expected to use the wash facilities. Petitioners opined that the inadequacy of the wash facilities would lead to washing being done outside of the facilities, and to the resulting waste and wash water entering the stormwater management system. Petitioners provided no basis for the supposition other than speculation. Mr. Stone testified that the horse-washing facilities are adequate to handle the horses boarded at the stables and those horses that would reasonably be expected to use the facility during events. His testimony in that regard was credible and is accepted. Based on the foregoing, the Applicants have provided reasonable assurances that the horse-washing facilities are adequate to prevent the release of wash water to the stormwater management system or Moose Lake. Petitioners expressed further concerns that horse washing outside of the horse-washing facilities would be facilitated due to the location of hose bibs along the exterior stable walls. However, Mr. Swakon testified that those concerns would be minimized if the hose bibs could be disabled to prevent the attachment of hoses. The December 2012 Updated BMP Plan requires such disabling, and Mr. Stone testified that the threads have been removed. Based on the foregoing, the Applicants have provided reasonable assurances that the presence of hose bibs on the exterior stable walls will not result in conditions that would allow for the release of wash water to the stormwater management system or Moose Lake. Best Management Practices The Updated BMP Plan for the Complex includes practices that are more advanced than the minimum requirements of the Village of Wellington, and more stringent than BMPs approved for other equestrian facilities in Wellington. Petitioners identified several issues related to the Updated BMP Plan that allegedly compromised the ability of the Complex to meet and maintain standards. Those issues included: the lack of a requirement that the Applicant provide the District with a copy of the contract with a Village of Wellington-approved manure hauler; the failure to require that BMP Officers be independent of the Applicants; the failure to require that the names and telephone numbers of the BMP Officers be listed in the permit; and the failure of the District to require that violations by tenants be reported to the District, rather than being maintained on-site as required. Mr. Stone testified that the BMP conditions included in the Updated BMP Plan were sufficient to assure compliance. His testimony is credited. Based on the foregoing, the Applicants have provided reasonable assurances that the terms and conditions of the Updated BMP Plan are capable of being implemented and enforced. Permitting Standards - Applicant Capabilities Provisions of rule 40E-4.301 that remain at issue in this proceeding, and that are based on the capabilities of the Applicants to implement the Permit, are as follows: In order to obtain a standard general, individual, or conceptual approval permit under this chapter . . . an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal or abandonment of a surface water management system: * * * Will be conducted by an entity with the sufficient financial, legal and administrative capability to ensure that the activity will be undertaken in accordance with the terms and conditions of the permit, if issued. As the owners of the Complex property, the Applicants have the legal authority to ensure that their tenants, licensees, invitees, and agents exercise their rights to the property in a manner that does not violate applicable laws, rules, and conditions. Regarding the financial capability of the Applicants to ensure the successful and compliant operation of the Complex, Mr. Stone testified that the entity that owns the Applicants, Wellington Equestrian Partners, has considerable financial resources backing the Complex venture. Furthermore, the Applicants own the property on and adjacent to the Complex which is itself valuable. As to the administrative capabilities of the Applicants to ensure that the activities on the site will comply with relevant standards, Mr. Stone testified that an experienced and financially responsible related entity, Equestrian Sport Productions, by agreement with the Applicants, is charged with organizing and operating events at the Complex, and that the Applicants’ BMP Officers have sufficient authority to monitor activities and ensure compliance with the BMPs by tenants and invitees. Mr. Stone’s testimony that the Applicants have the financial and administrative capability to ensure that events and other operations will be conducted in a manner to ensure that the stormwater management system conditions, including BMPs, will be performed was persuasive and is accepted. The fact that the Applicants are financially and administratively backed by related parent and sibling entities does not diminish the reasonable assurances provided by the Applicants that the construction, operation, and maintenance of the Complex will be undertaken in accordance with the Permit. Petitioners assert that many of the events to be held at the Complex are sanctioned by international equestrian organizations, and that their event rules and requirements -- which include restrictions on the ability to remove competition teams from the grounds -- limit the Applicants’ ability to enforce the BMPs. Thus, the Petitioners suggest that reasonable assurances cannot be provided as a result of the restrictions imposed by those sanctioning bodies. The international event rules applicable to horses and riders are not so limiting as to diminish the reasonable assurances that have been provided by the Applicants. Based on the foregoing, the Applicants have provided reasonable assurances that construction and operation of the stormwater management system will be conducted by entities with sufficient financial, legal, and administrative capability to ensure compliance with the terms and conditions of the permit. As a related matter, Petitioners assert the Applicants failed to disclose all of their contiguous land holdings, thus making it impossible for the District to calculate the actual impact of the Complex. Although the application was, for a number of items, an evolving document, the evidence demonstrates that the Applicants advised the District of their complete 59+- acre holdings, and that the Permit was based on a complete disclosure. The circumstances of the disclosure of the Applicant’s property interests in the area adjacent to the Complex was not a violation of applicable standards, and is not a basis for denial of the Complex permit. Permitting Standards - C-51 Basin Rule The final provision of rule 40E-4.301 that is at issue in this proceeding is as follows: In order to obtain a standard general, individual, or conceptual approval permit under this chapter . . . an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal or abandonment of a surface water management system: * * * Will comply with any applicable special basin or geographic area criteria established in Chapter 40E-41, F.A.C. Mr. Hall testified the Complex violated permitting standards partly because it failed to comply with the C-51 Basin rule, Florida Administrative Code Rule 40E-041, Part III, pertaining to on-site compensation for reductions in soil storage volume. Mr. Waterhouse testified that the C-51 Basin rule does not apply to the lands encompassed by the Acme Improvement District permits, including the Complex property. The C-51 Basin rule was promulgated in 1987, after the issuance of the original Acme Improvement District permit. The District does not apply new regulatory standards to properties that are the subject of a valid permit or its modifications. Therefore, the area encompassed by the 1978 Acme Permit, and activities permitted in that area as a modification to the 1978 Acme Permit, are not subject to the C-51 rule. The Joint Prehearing Stipulation provides that “Chapter 373, Fla. Stat., Chapter 40E-4, Fla. Admin. Code, and the Basis of Review for Environmental Resource Permit Applications within the South Florida Water Management District (July 4, 2010) are the applicable substantive provisions at issue in this proceeding.” The Stipulation did not identify chapter 40E-41 as being applicable in this proceeding. Given the testimony of Mr. Waterhouse, which correctly applies standards regarding the application of subsequently promulgated rules to existing permits, and the stipulation of the parties, the C-51 Basin rule, Florida Administrative Code Rule 40-E-041, Part III, does not apply to the permit that is the subject of this proceeding. Therefore, the stormwater management system does not violate rule 40E-4.301(1)(k). Consideration of Violations Florida Administrative Code Rule 40E-4.302(2), provides, in pertinent part, that: When determining whether the applicant has provided reasonable assurances that District permitting standards will be met, the District shall take into consideration a permit applicant’s violation of any . . . District rules adopted pursuant to Part IV, Chapter 373, F.S., relating to any other project or activity and efforts taken by the applicant to resolve these violations. . . . Petitioners have identified several violations of District rules on or adjacent to the Complex property during the course of construction, and violations of District rules associated with the Palm Beach International Equestrian Center (PBIEC), the owner of which shares common managers and officers with the Applicants, for consideration in determining whether reasonable assurances have been provided. Violations on or Adjacent to the Complex On March 22, 2012, the District performed an inspection of the Complex property. The inspection revealed that the Applicants had constructed the linear berm along the eastern side of the Property that was the subject of the January 25, 2012, application for modification of the Permit. The construction was performed before a permit modification was issued, and was therefore unauthorized. A Notice of Violation was issued to Far Niente Stables II, LLC, on March 22, 2012, that instructed Far Niente Stables II, LLC, to cease all work on the Complex. Several draft consent orders were provided to Far Niente Stables II, LLC, each of which instructed Far Niente Stables II, LLC, to cease and desist from further construction. Construction was not stopped until April 18, 2012. The matter was settled through the entry of a Consent Order on May 10, 2012 that called for payment of costs and civil penalties. The berm was authorized as part of the March 26, 2012 Complex permit modification. All compliance items were ultimately completed to the satisfaction of the District During inspections of the Complex by the parties to this proceeding, it was discovered that yard drains had been constructed between the stables and connected to the stormwater management system, and that a bathroom/utility room had been constructed at the north end of the horse-washing facility. The structures were not depicted in any plans submitted to the District, and were not authorized by the Permit. The yard drains had the potential to allow for animal waste to enter Moose Lake. The Applicants, under instruction from the District, have capped the yard drains. No other official compliance action has been taken by the District. A permit condition to ensure that the yard drains remain capped is appropriate and warranted. At some time during or before 2010, a mound of fill material was placed on the derby and grand prix field to the north of the Complex to be used as an event obstacle. Although there was a suggestion that a permit should have been obtained prior to the fill being placed, the District has taken no enforcement action regarding the earthen mound. Petitioners noted that the Complex is being operated, despite the fact that no notice of completion has been provided, and no conversion from the construction phase to the operation phase has been performed as required by General Condition Nos. 6 and 7 of the Complex permit. Such operations constitute a violation of the permit and, as such, a violation of District rules. However, the District has taken no official action to prohibit or restrict the operation of the Complex pending completion and certification of the permitted work and conversion of the permit to its operation phase. The construction of the berm, yard drains, and bathroom/utility room, and the operation of the Complex, causes concern regarding the willingness of the Applicants to work within the regulatory parameters designed to ensure protection of Florida’s resources. However, given the scope of the Complex as a whole, and given that the violations were resolved to the satisfaction of the District, the violations, though considered, do not demonstrate a lack of reasonable assurances that District permitting standards will be met. Violations related to the PBIEC At some time prior to February 13, 2008, one or more entities affiliated with Mark Bellissimo assumed control and operation of the PBIEC. When the facility was acquired, the show grounds were in poor condition, there were regulatory violations, it had no BMPs of consequence, there were no covered horse-wash racks, and the wash water was not discharged to a sanitary sewer system. After its acquisition by entities associated with Mr. Bellissimo, the PBIEC was substantially redesigned and rebuilt, and BMPs that met or exceeded the requirements of the Village of Wellington were implemented. The PBIEC currently has 12 arenas that include facilities for show jumping events, and nine horse-wash racks. The PBIEC has the capacity to handle approximately 1,700 horses. On March 14, 2008, the District issued a Notice of Violation to Far Niente Stables V, LLC, related to filling and grading of an existing stormwater management system and lake system at the PBIEC; the failure to maintain erosion and turbidity controls to prevent water quality violations in adjacent waters; the failure to maintain manure and equestrian waste BMPs; and the failure to transfer the PBIEC stormwater management permit to the current owner. On October 9, 2008, Far Niente Stables V, LLC, and the District entered into a Consent Order that resolved the violations at the PBIEC, required that improvements be made, required the implementation of advanced BMPs, and required payment of costs and civil penalties. On January 12, 2011, a notice was issued that identified deficiencies in the engineer’s construction completion certification for the stormwater management system improvements, horse-wash facility connections, and other activities on the PBIEC. Although completion of all items required by the Consent Order took longer -- in some instances significantly longer -- than the time frames set forth in the Consent Order,6/ all compliance items were ultimately completed to the satisfaction of the District. On January 7, 2011, the District issued a Notice of Violation and short-form Consent Order to Far Niente Stables, LLC, which set forth violations that related to the failure to obtain an environmental resource permit related to “Tract D and Equestrian Club Drive Realignment.” The short-form Consent Order was signed by Far Niente Stables, LLC, and the compliance items were ultimately completed to the satisfaction of the District. Based on the foregoing, the violations at the PBIEC, though considered, do not demonstrate a lack of reasonable assurances that District permitting standards will be met for the Complex Permit.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law set forth herein it is RECOMMENDED that the South Florida Water Management District enter a final order: Incorporating the June 29, 2012, Order of Standing and Timeliness; Approving the issuance of Surface Water Management System Permit No. 50-00548-S-203 to Far Niente Stables II, LLC; Polo Field One, LLC; Stadium North, LLC; and Stadium South, LLC.; and Imposing, as an additional condition, a requirement that the unpermitted yard drains constructed between the stables be permanently capped, and the area graded, to prevent the unauthorized introduction of equine waste from the area to the stormwater management system. DONE AND ENTERED this 26th day of April, 2013, in Tallahassee, Leon County, Florida. S E. GARY EARLY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 26th day of April, 2013.
The Issue The issue to be determined is whether Consumptive Use Permit No. 2-083-91926-3, and Environmental Resource Permit No. IND-083-130588-4 should be issued as proposed in the respective proposed agency actions issued by the St. Johns River Water Management District.
Findings Of Fact The Parties Sierra Club, Inc., is a national organization, the mission of which is to explore, enjoy, and advocate for the environment. A substantial number of Sierra Club’s 28,000 Florida members utilize the Silver River, Silver Springs, the Ocklawaha River, and the St. Johns River for water-based recreational activities, which uses include kayaking, swimming, fishing, boating, canoeing, nature photography, and bird watching. St. Johns Riverkeeper, Inc., is one of 280 members of the worldwide Waterkeepers Alliance. Its mission is to protect, restore, and promote healthy waters of the St. Johns River, its tributaries, springs, and wetlands -- including Silver Springs, the Silver River, and the Ocklawaha River -- through citizen- based advocacy. A substantial number of St. Johns Riverkeeper’s more than 1,000 members use and enjoy the St. Johns River, the Silver River, Silver Springs, and the Ocklawaha River for boating, fishing, wildlife observation, and other water-based recreational activities. Karen Ahlers is a native of Putnam County, Florida, and lives approximately 15 miles from the Applicant’s property on which the permitted uses will be conducted. Ms. Ahlers currently uses the Ocklawaha River for canoeing, kayaking, and swimming, and enjoys birding and nature photography on and around the Silver River. Over the years, Ms. Ahlers has advocated for the restoration and protection of the Ocklawaha River, as an individual and as a past-president of the Putnam County Environmental Council. Jeri Baldwin lives on a parcel of property in the northeast corner of Marion County, approximately one mile from the Applicant’s property on which the permitted uses will be conducted. Ms. Baldwin, who was raised in the area, and whose family and she used the resources extensively in earlier years, currently uses the Ocklawaha River for boating. Florida Defenders of the Environment (FDE) is a Florida corporation, the mission of which is to conserve and protect and restore Florida's natural resources and to conduct environmental education projects. A substantial number of FDE’s 186 members, of which 29 reside in Marion County, Florida, use and enjoy Silver Springs, the Silver River, and the Ocklawaha Aquatic Preserve, and their associated watersheds in their educational and outreach activities, as well as for various recreational activities including boating, fishing, wildlife observation, and other water-based recreational activities. Sleepy Creek Lands, LLC (Sleepy Creek or Applicant), is an entity registered with the Florida Department of State to do business in the state of Florida. Sleepy Creek owns approximately 21,000 acres of land in Marion County, Florida, which includes the East Tract and the North Tract on which the activities authorized by the permits are proposed. St. Johns River Water Management District (SJRWMD or District) is a water-management district created by section 373.069(1). It has the responsibility to conserve, protect, manage, and control the water resources within its geographic boundaries. See § 373.069(2)(a), Fla. Stat. The Consumptive Use Permit The CUP is a modification and consolidation of two existing CUP permits, CUP No. 2-083-3011-7 and CUP No. 2-083- 91926-2, which authorize the withdrawal of 1.46 mgd from wells located on the East Tract. Although the existing CUP permits authorize an allocation of 1.46 mgd, actual use has historically been far less, and rarely exceeded 0.3 mgd. The proposed CUP modification will convert the authorized use of water from irrigation of 1,010 acres of sod grass on the East Tract, to supplemental irrigation of improved pasture for grass and other forage crops (approximately 97 percent of the proposed withdrawals) and cattle watering (approximately three percent of the proposed withdrawals) on the North Tract and the East Tract. An additional very small amount will be used in conjunction with the application of agricultural chemicals. CUP No. 2-083-3011-7 is due to expire in 2021. CUP No. 2-083-91926-2 is due to expire in 2024. In addition to the consolidation of the withdrawals into a single permit, the proposed agency action would extend the term of the consolidated permit to 20 years from issuance, with the submission of a compliance report due 10 years from issuance. Sleepy Creek calculated a water demand of 2.569 mgd for the production of grasses and forage crops necessary to meet the needs for grass-fed beef production, based on the expected demand in a 2-in-10 drought year. That calculation is consistent with that established in CUP Applicant’s Handbook (CUP A.H.) section 12.5.1. The calculated amount exceeds the authorized average allocation of 1.46 mgd. Mr. Jenkins testified as to the District’s understanding that the requested amount would be sufficient, since the proposed use was a “scaleable-type project,” with adjustments to cattle numbers made as necessary to meet the availability of feed. Regardless of demand, the proposed permit establishes the enforceable withdrawal limits applicable to the property. With regard to the East Tract, the proposed agency action reduces the existing 1.46 mgd allocation for that tract to a maximum allocation of 0.464 mgd, and authorizes the irrigation of 611 acres of pasture grass using existing extraction wells and six existing pivots. With regard to the North Tract, the proposed agency action authorizes the irrigation of 1,620 acres of pasture and forage grain crops using 15 center pivot systems. Extraction wells to serve the North Tract pivots will be constructed on the North Tract. The proposed North Tract withdrawal wells are further from Silver Springs than the current withdrawal locations. The proposed CUP allows Sleepy Creek to apply the allocated water as it believes to be appropriate to the management of the cattle operation. Although the East Tract is limited to a maximum of 0.464 mgd, there is no limitation on the North Tract. Thus, Sleepy Creek could choose to apply all of the 1.46 mgd on the North Tract. For that reason, the analysis of impacts from the irrigation of the North Tract has generally been based on the full 1.46 mgd allocation being drawn from and applied to the North Tract. The Environmental Resource Permit As initially proposed, the CUP had no elements that would require issuance of an ERP. However, in order to control the potential for increased runoff and nutrient loading resulting from the irrigation of the pastures, Sleepy Creek proposes to construct a stormwater management system to capture runoff from the irrigated pastures, consisting of a series of vegetated upland buffers, retention berms and redistribution swales between the pastures and downgradient wetland features. Because the retention berm and swale system triggered the permitting thresholds in rule 62-330.020(2)(d) (“a total project area of more than one acre”) and rule 62-330.020(2)(e) (“a capability of impounding more than 40 acre-feet of water”), Sleepy Creek was required to obtain an Environmental Resource Permit for its construction. Regional Geologic Features To the west of the North Tract is a geologic feature known as the Ocala Uplift or Ocala Platform, in which the limestone that comprises the Floridan aquifer system exists at or very near the land surface. Karst features, including subterranean conduits and voids that can manifest at the land surface as sinkholes, are common in the Ocala Uplift due in large part to the lack of consolidated or confining material overlaying the limestone. Water falling on the surface of such areas tends to infiltrate rapidly through the soil into the Floridan aquifer, occasionally through direct connections such as sinkholes. The lack of confinement in the Ocala Uplift results in few if any surface-water features such as wetlands, creeks, and streams. As one moves east from the Ocala Uplift, a geologic feature known as the Cody Escarpment becomes more prominent. In the Cody Escarpment, the limestone becomes increasingly overlain by sands, shell, silt, clays, and other less permeable sediments of the Hawthorn Group. The North Tract and the East Tract lie to the east of the point at which the Cody Escarpment becomes apparent. As a result, water tends to flow overland to wetlands and other surface water features. The Property The North and East Tracts are located in northern Marion County near the community of Fort McCoy. East Tract Topography and Historic Use The East Tract is located in the Daisy Creek Basin, and includes the headwaters of a small creek that drains directly to the Ocklawaha River. The historic use of the East Tract has been as a cleared 1,010-acre sod farm. The production of sod included irrigation, fertilization, and pest control. Little change in the topography, use, and appearance of the property will be apparent as a result of the permits at issue, but for the addition of grazing cattle. The current CUPs that are subject to modification in this proceeding authorize groundwater withdrawals for irrigation of the East Tract at the rate of 1.46 mgd. Since the proposed agency action has the result of reducing the maximum withdrawal from wells on the East Tract to 0.464 mgd, thus proportionately reducing the proposed impacts, there was little evidence offered to counter Sleepy Creek’s prima facie case that reasonable assurance was provided that the proposed East Tract groundwater withdrawal allocation will meet applicable CUP standards. There are no stormwater management structures to be constructed on the East Tract. Therefore, the ERP permit discussed herein is not applicable to the East Tract. North Tract Topography and Historic Use The North Tract has a generally flat topography, with elevations ranging from 45 feet to 75 feet above sea level. The land elevation is highest at the center of the North Tract, with the land sloping towards the Ocklawaha River to the east, and to several large wet prairie systems to the west. Surface water features on the North Tract include isolated, prairie, and slough-type wetlands on approximately 28 percent of the North Tract, and a network of creeks, streams, and ditches, including the headwaters of Mill Creek, a contributing tributary of the Ocklawaha River. A seasonal high groundwater elevation on the North Tract is estimated at 6 to 14 inches below ground surface. The existence of defined creeks and surface water features supports a finding that the North Tract is underlain by a relatively impermeable confining layer that impedes the flow of water from the surface and the shallow surficial aquifer to the upper Floridan and lower Floridan aquifers. If there was no confining unit, water going onto the surface of the property, either in the form of rain or irrigation water, would percolate unimpeded to the lower aquifers. Areas in the Ocala Uplift to the west of the North Tract, where the confining layer is thinner and discontiguous, contain few streams or runoff features. Historically, the North Tract was used for timber production, with limited pasture and crop lands. At the time the 7,207-acre North Tract was purchased by Sleepy Creek, land use consisted of 4,061 acres of planted pine, 1,998 acres of wetlands, 750 acres of improved pasture, 286 acres of crops, 78 acres of non-forested uplands, 20 acres of native forest, 10 acres of open water, and 4 acres of roads and facilities. Prior to the submission of the CUP and ERP applications, much of the planted pine was harvested, and the land converted to improved pasture. Areas converted to improved pasture include those proposed for irrigation, which have been developed in the circular configuration necessary for future use with center irrigation pivots. As a result of the harvesting of planted pine, and the conversion of about 345 acres of cropland and non-forested uplands to pasture and incidental uses, total acreage in pasture on the North Tract increased from 750 acres to 3,938 acres. Other improvements were constructed on the North Tract, including the cattle processing facility. Aerial photographs suggest that the conversion of the North Tract to improved pasture and infrastructure to support a cattle ranch is substantially complete. The act of converting the North Tract from a property dominated by planted pine to one dominated by improved pasture, and the change in use of the East Tract from sod farm to pasture, were agricultural activities that did not require a permit from the District. As such, there is no impropriety in considering the actual, legal use of the property in its current configuration as the existing use for which baseline conditions are to be measured. Petitioners argue that the baseline conditions should be measured against the use of the property as planted pine plantation, and that Sleepy Creek should not be allowed to “cattle-up” before submitting its permit applications, thereby allowing the baseline to be established as a higher impact use. However, the applicable rules and statutes provide no retrospective time-period for establishing the nature of a parcel of property other than that lawfully existing when the application is made. See West Coast Reg’l Water Supply Auth. v. SW Fla. Water Mgmt. Dist., Case No. 95-1520 et seq., ¶ 301 (Fla. DOAH May 29, 1997; SFWMD ) (“The baseline against which projected impacts conditions [sic] are those conditions, including previously permitted adverse impacts, which existed at the time of the filing of the renewal applications.”). The evidence and testimony in this case focused on the effects of the water allocation on the Floridan aquifer, Silver Springs, and the Silver River, and on the effects of the irrigation on water and nutrient transport from the properties. It was not directed at establishing a violation of chapter 373, the rules of the SJRWMD, or the CUP Applicant’s Handbook with regard to the use and management of the agriculturally-exempt unirrigated pastures, nor did it do so. Soil Types Soils are subject to classifications developed by the Soil Conservation Service based on their hydrologic characteristics, and are grouped into Group A, Group B, Group C, or Group D. Factors applied to determine the appropriate hydrologic soil group on a site-specific basis include depth to seasonal high saturation, the permeability rate of the most restrictive layer within a certain depth, and the depth to any impermeable layers. Group A includes the most well-drained soils, and Group D includes the most poorly-drained soils. Group D soils are those with seasonal high saturation within 24 inches of the soil surface and a higher runoff potential. The primary information used to determine the hydrologic soil groups on the North Tract was the depth to seasonal-high saturation, defined as the highest expected annual elevation of saturation in the soil. Depth to seasonal-high saturation was measured through a series of seven hand-dug and augered soil borings completed at various locations proposed for irrigation across the North Tract. In determining depth to seasonal-high saturation, the extracted soils were examined based on depth, color, texture, and other relevant characteristics. In six of the seven locations at which soil borings were conducted, a restrictive layer was identified within 36 inches of the soil surface. At one location at the northeastern corner of the North Tract, the auger hole ended at a depth of 48 inches -- the length of the auger -- at which depth there was an observable increase in clay content but not a full restrictive layer. However, while the soil assessment was ongoing, a back-hoe was in operation approximately one hundred yards north of the boring location. Observations of that excavation revealed a heavy clay layer at a depth of approximately 5 feet. In each of the locations, the depth to seasonal-high saturation was within 14 inches of the soil surface. Based on the consistent observation of seasonal-high saturation at each of the sampled locations, as well as the flat topography of the property with surface water features, the soils throughout the property, with the exception of a small area in the vicinity of Pivot 6, were determined to be in hydrologic soil Group D. Hydrogeologic Features There are generally five hydrogeologic units underlying the North Tract, those units being the surficial aquifer system, the intermediate confining unit, the upper Floridan aquifer, the middle confining unit, and the lower Floridan aquifer. In areas in which a confining layer is present, water falling on the surface of the land flows over the surface of the land or across the top of the confining layer. A surficial aquifer, with a relatively high perched water table, is created by the confinement and separation of surface waters from the upper strata of the Floridan aquifer. Surface waters are also collected in or conveyed by various surface water features, including perched wetlands, creeks, and streams. The preponderance of the evidence adduced at the final hearing demonstrates that the surficial aquifer exists on the property to a depth of up to 20 feet below the land surface (bls). Beneath the surficial aquifer is an intermediate confining unit of dense clay interspersed with beds of sand and calcareous clays that exists to a depth of up to 100 feet bls. The clay material observed on the North Tract is known as massive or structureless. Such clays are restrictive with very low levels of hydraulic conductivity, and are not conducive to development of preferential flow paths to the surficial or lower aquifers. The intermediate confining unit beneath the North Tract restricts the exchange of groundwater from the surficial aquifer to the upper Floridan aquifer. The upper Floridan aquifer begins at a depth of approximately 100 feet bls, and extends to a depth of approximately 340 feet bls. At about 340 feet bls, the upper Floridan aquifer transitions to the middle confining unit, which consists of finely grained, denser material that separates the interchange of water between the upper Floridan aquifer and the lower Floridan aquifer. Karst Features Karst features form as a result of water moving through rock that comprises the aquifer, primarily limestone, dissolving and forming conduits in the rock. Karst areas present a challenging environment to simulate through modeling. Models assume the subsurface to be a relatively uniform “sand box” through which it is easier to simulate groundwater flow. However, if the subsurface contains conduits, it becomes more difficult to simulate the preferential flows and their effect on groundwater flow paths and travel times. The District has designated parts of western Alachua County and western Marion County as a Sensitive Karst Area Basin. A Sensitive Karst Area is a location in which the porous limestone of the Floridan aquifer occurs within 20 feet of the land surface, and in which there is 10 to 20 inches of annual recharge to the Floridan aquifer. The designation of an area as being within the Sensitive Karst Area Basin does not demonstrate that it does, or does not, have subsurface features that are karstic in nature, or that would provide a connection between the surficial aquifer and the Floridan aquifer. The western portion of the North Tract is within the Sensitive Karst Area Basin. The two intensive-use areas on the North Tract that have associated stormwater facilities -- the cattle unloading area and the processing facility -- are outside of the Sensitive Karst Area Basin. The evidence was persuasive that karst features are more prominent to the west of the North Tract. In order to evaluate the presence of karst features on the North Tract, Mr. Andreyev performed a “desktop-type evaluation,” with a minimal field survey. The desktop review included a review of aerial photographs and an investigation of available data, including the Florida Geological Survey database of sinkhole occurrence in the area. The aerial photographs showed circular depressions suggestive of karst activity west and southwest of the North Tract, but no such depressions on the North Tract. Soil borings taken on the North Tract indicated the presence of layers of clayey sand, clays, and silts at a depth of 70 to 80 feet. Well-drilling logs taken during the development of the wells used for an aquifer performance test on the North Tract showed the limestone of the Floridan aquifer starting at a depth below ground surface of 70 to 80 feet. Other boring data generated on the North Tract suggests that there is greater than 100 feet of clay and sandy clay overburden above the Floridan aquifer on and in the vicinity of the North Tract. Regardless of site-specific differences, the observed confining layer separating the surficial aquifer from the Floridan aquifer is substantial, and not indicative of a karst environment. Aquifer performance tests performed on the North Tract were consistent in showing that drawdown in the surficial aquifer from the tests was minimal to non-detectable, which is strong evidence of an intact and low-permeability confining layer. The presence of well-developed drainage features on the North Tract is further evidence of a unit of confinement that is restricting water from going deeper into the subsurface, and forcing it to runoff to low-lying surface water features. Petitioners’ witnesses did not perform any site- specific analysis of karst features on or around the Sleepy Creek property. Their understanding of the nature of the karst systems in the region was described as “hypothetical or [] conceptual.” Dr. Kincaid admitted that he knew of no conduits on or adjacent to the North Tract. As a result of the data collected from the North Tract, Mr. Hearn opined that the potential for karst features on the property that provide an opening to the upper Floridan aquifer “is extremely remote.” Mr. Hearn’s opinion is consistent with the preponderance of the evidence in this case, and is accepted. In the event a surface karst feature were to manifest itself, Sleepy Creek has proposed that the surface feature be filled and plugged to reestablish the integrity of the confining layer. More to the point, the development of a surficial karst feature in an area influenced by irrigation would be sufficient grounds for the SJRWMD to reevaluate and modify the CUP to account for any changed conditions affecting the assumptions and bases for issuance of the CUP. Silver Springs, the Silver River, and the Ocklawaha River The primary, almost exclusive concern of Petitioners was the effect of the modified CUP and the nutrients from the proposed cattle ranch on Silver Springs, the Silver River, and the Ocklawaha River. Silver Springs Silver Springs has long been a well-known attraction in Florida. It is located just to the east of Ocala, Florida. Many of the speakers at the public comment period of this proceeding spoke fondly of having frequented Silver Springs over the years, enjoying its crystal clear waters through famous glass-bottomed boats. For most of its recorded history, Silver Springs was the largest spring by volume in Florida. Beginning in the 1970s, it began to lose its advantage, and by the year 2000, Rainbow Springs, located in southwestern Marion County, surpassed Silver Springs as the state’s largest spring. Silver Springs exists at the top of the potentiometric surface of the Floridan aquifer. Being at the “top of the mountain,” when water levels in the Floridan aquifer decline, groundwater flow favors the lower elevation springs. Thus, surrounding springshed boundaries expand to take more water to maintain their baseflows, at the expense of the Silver Springs springshed, which contracts. Rainbow Springs shares an overlapping springshed with Silver Springs. The analogy used by Dr. Knight was of the aquifer as a bucket with holes at different levels, and with the Silver Springs “hole” near the top of the bucket. When the water level in the bucket is high, water will flow from the top hole. As the water level drops below that hole, it will preferentially flow from the lower holes. Rainbow Springs has a vent or outlet from the aquifer, that is 10 feet lower in elevation than that of Silver Springs. Coastal springs are lower still. Thus, as groundwater levels decline, the lower springs “pirate flow” from the upper springs. Since the first major studies of Silver Springs were conducted in the 1950s, the ecosystem of Silver Springs has undergone changes. The water clarity, though still high as compared to other springs, has been reduced by 10 to 15 percent. Since the 1950s, macrophytic plants, i.e., rooted plants with seeds and flowers, have declined in population, while epiphytic and benthic algae have increased. Those plants are sensitive to increases in nitrogen in the water. Thus, Dr. Knight’s opinion that increases in nitrogen emerging from Silver Springs, calculated to have risen from just over 0.4 mg/l in the 1950s, to 1.1 mg/l in 2004, and to up to 1.5 mg/l at present,1/ have caused the observed vegetative changes is accepted. Silver River Silver Springs forms the headwaters for the Silver River, a spring run 5 1/2 miles in length, at which point it becomes a primary input to the Ocklawaha River. Issues of water clarity and alteration of the vegetative regime that exist at Silver Springs are also evident in the Silver River. In addition, the reduction in flow allows for more tannic water to enter the river, further reducing clarity. Dr. Dunn recognized the vegetative changes in the river, and opined that the “hydraulic roughness” caused by the increase in vegetation is likely creating a spring pool backwater at Silver Springs, thereby suppressing some of the flow from the spring. The Silver River has been designated as an Outstanding Florida Water. There are currently no Minimum Flows and Levels established by the District for the Silver River. Ocklawaha River The Ocklawaha River originates near Leesburg, Florida, at the Harris Chain of Lakes, and runs northward past Silver Springs. The Silver River is a major contributor to the flow of the Ocklawaha River. Due to the contribution of the Silver River and other spring-fed tributaries, the Ocklawaha River can take on the appearance of a spring run during periods of low rainfall. Historically, the Ocklawaha River flowed unimpeded to its confluence with the St. Johns River in the vicinity of Palatka, Florida. In the 1960s, as part of the Cross-Florida Barge Canal project, the Rodman Dam was constructed across the Ocklawaha River north of the Sleepy Creek property, creating a large reservoir known as the Rodman Pool. Dr. Knight testified convincingly that the Rodman Dam and Pool have altered the Ocklawaha River ecosystem, precipitating a decline in migratory fish populations and an increase in filamentous algae. At the point at which the Ocklawaha River flows past the Sleepy Creek property, it retains its free-flowing characteristics. Mill Creek, which has its headwaters on the North Tract, is a tributary of the Ocklawaha River. The Ocklawaha River, from the Eureka Dam south, has been designated as an Outstanding Florida Water. However, the Ocklawaha River at the point at which Mill Creek or other potential surface water discharges from the Sleepy Creek property might enter the river are not included in the Outstanding Florida Water designation. There are currently no Minimum Flows and Levels established by the District for the Ocklawaha River. The Silver Springs Springshed A springshed is that area from which a spring draws water. Unlike a surface watershed boundary, which is fixed based on land features, contours, and elevations, a springshed boundary is flexible, and changes depending on a number of factors, including rainfall. As to Silver Springs, its springshed is largest during periods of more abundant rainfall when the aquifer is replenished, and smaller during drier periods when groundwater levels are down, and water moves preferentially to springs and discharge points that are lower in elevation. The evidence in this case was conflicting as to whether the North Tract is in or out of the Silver Springs springshed boundary. Dr. Kincaid indicated that under some of the springshed delineations, part of the North Tract was out of the springshed, but over the total period of record, it is within the springshed. Thus, it was Dr. Kincaid’s opinion that withdrawals anywhere within the region will preferentially impact Silver Springs, though he admitted that he did not have the ability to quantify his opinion. Dr. Knight testified that the North Tract is within the Silver Springs “maximum extent” springshed at least part of the time, if not all the time. He did not opine as to the period of time in which the Silver Springs springshed was at its maximum extent. Dr. Bottcher testified that the North Tract is not within the Silver Springs springshed because there is a piezometric rise between North Tract and Silver Springs. Thus, in his opinion, withdrawals at the North Tract would not be withdrawing water going to Silver Springs. Dr. Dunn agreed that the North Tract is on the groundwater divide for Silver Springs. In his view, the North Tract is sometimes in, and sometimes out of the springshed depending on the potentiometric surface. In his opinion, the greater probability is that the North Tract is more often outside of the Silver Springs springshed, with seasonal and year—to—year variation. Dr. Dunn’s opinion provides the most credible explanation of the extent to which the North Tract sits atop that portion of the lower Floridan aquifer that feeds to Silver Springs. Thus, it is found that the groundwater divide exists to the south of the North Tract for a majority of the time, and water entering the Floridan aquifer from the North Tract will, more often than not, flow away from Silver Springs. Silver Springs Flow Volume The Silver Springs daily water discharge has been monitored and recorded since 1932. Over the longest part of the period of record, up to the 1960s, flows at Silver Springs averaged about 800 cubic feet per second (cfs). Through 1989, there was a reasonable regression between rainfall and springflow, based on average rainfalls. The long-term average rainfall in Ocala was around 50 inches per year, and long-term springflow was about 800 cfs, with deviations from average generally consistent with one another. Between 1990 and 1999, the relationship between rainfall and springflow declined by about 80 cubic feet per second. Thus, with average rainfall of 50 inches per year, the average springflow was reduced to about 720 cfs. From 2000 to 2009, there was an additional decline, such that the total cumulative decline for the 20-year period through 2009 was 250 cfs. Dr. Dunn agreed with Dr. Knight that after 2000, there was an abrupt and persistent reduction in flow of about 165 cfs. However, Dr. Dunn did not believe the post-2000 flow reduction could be explained by rainfall directly, although average rainfall was less than normal. Likewise, groundwater withdrawals did not offer an adequate explanation. Dr. Dunn described a natural 30-year cycle of wetter and drier periods known as the Atlantic Multidecadal Oscillation (AMO) that has manifested itself over the area for the period of record. From the 1940s up through 1970, the area experienced an AMO wet cycle with generally higher than normal rainfall at the Ocala rain station. For the next 30-year period, from 1970 up to 2000, the Ocala area ranged from a little bit drier to some years in which it was very, very dry. Dr. Dunn attributed the 80 cfs decline in Silver Springs flow recorded in the 1990s to that lower rainfall cycle. After 2000, when the next AMO cycle would be expected to build up, as it did post—1940, it did not happen. Rather, there was a particularly dry period around 2000 that Dr. Dunn believes to have had a dramatic effect on the lack of recovery in the post-2000 flows in the Silver River. According to Mr. Jenkins, that period of deficient rainfall extended through 2010. Around the year 2001, the relationship between rainfall and flow changed such that for a given amount of rainfall, there was less flow in the Silver River, with flow dropping to as low as 535 cfs after 2001. It is that reduction in flow that Dr. Knight has attributed to groundwater withdrawals. It should be noted that the observed flow of Silver Springs that formed the 1995 baseline conditions for the North Central Florida groundwater model that will be discussed herein was approximately 706 cfs. At the time of the final hearing in August 2014, flow at Silver Springs was 675 cfs. The reason offered for the apparent partial recovery was higher levels of rainfall, though the issue was not explored in depth. For the ten-year period centered on the year 2000, local water use within Marion and Alachua County, closer to Silver Springs, changed little -- around one percent per year. From a regional perspective, groundwater use declined at about one percent per year for the period from 1990 to 2010. The figures prepared by Dr. Knight demonstrate that the Sleepy Creek project area is in an area that has a very low density of consumptive use permits as compared to areas adjacent to Silver Springs and more clearly in the Silver Springs springshed. In Dr. Dunn’s opinion, there were no significant changes in groundwater use either locally or regionally that would account for the flow reduction in Silver Springs from 1990 to 2010. In that regard, the environmental report prepared by Dr. Dunn and submitted with the CUP modification application estimated that groundwater withdrawals accounted for a reduction in flow at Silver Springs of approximately 20 cfs as measured against the period of record up to the year 2000, with most of that reduction attributable to population growth in Marion County. In the March 2014, environmental impacts report, Dr. Dunn described reductions in the stream flow of not only the Silver River, but of other tributaries of the lower Ocklawaha River, including the upper Ocklawaha River at Moss Bluff and Orange Creek. However, an evaluation of the Ocklawaha River water balance revealed there to be additional flow of approximately 50 cfs coming into the Ocklawaha River at other stations. Dr. Dunn suggested that changes to the vent characteristics of Silver Springs, and the backwater effects of increased vegetation in the Silver River, have resulted in a redistribution of pressure to other smaller springs that discharge to the Ocklawaha River, accounting for a portion of the diminished flow at Silver Springs. The Proposed Cattle Operation Virtually all beef cattle raised in Florida, upon reaching a weight of approximately 875 pounds, are shipped to Texas or Kansas to be fattened on grain to the final body weight of approximately 1,150 pounds, whereupon they are slaughtered and processed. The United States Department of Agriculture has a certification for grass—fed beef which requires that, after an animal is weaned, it can only be fed on green forage crops, including grasses, and on corn and grains that are cut green and before they set seed. The forage crops may be grazed or put into hay or silage and fed when grass and forage is dormant. The benefit of grass feeding is that a higher quality meat is produced, with a corresponding higher market value. Sleepy Creek plans to develop the property as a grass- fed beef production ranch, with pastures and related loading/unloading and slaughter/processing facilities where calves can be fattened on grass and green grain crops to a standard slaughter weight, and then slaughtered and processed locally. By so doing, Sleepy Creek expects to save the transportation and energy costs of shipping calves to the Midwest, and to generate jobs and revenues by employing local people to manage, finish, and process the cattle. As they currently exist, pastures proposed for irrigation have been cleared and seeded, and have “fairly good grass production.” The purpose of the irrigation is to enhance the production and quality of the grass in order to maintain the quality and reliability of feed necessary for the production of grass-fed beef. East Tract Cattle Operation The East Tract is 1,242 acres in size, substantially all of which was previously cleared, irrigated, and used for sod production. The proposed CUP permit authorizes the irrigation of 611 acres of pasture under six existing center pivots. The remaining 631 acres will be used as improved, but unirrigated, pasture. Under the proposed permit, a maximum of 1,207 cattle would be managed on the East Tract. Of that number, 707 cattle would be grazed on the irrigated paddocks, and 500 cattle would be grazed on the unirrigated improved pastures. If the decision is made to forego irrigation on the East Tract, with the water allocation being used on the North Tract or not at all, the number of cattle grazed on the six center pivot pastures would be decreased from 707 cattle to 484 cattle. The historic use of the East Tract as a sod farm resulted in high phosphorus levels in the soil from fertilization, which has made its way to Daisy Creek. Sleepy Creek has proposed a cattle density substantially below that allowed by application of the formulae in the Nutrient Management Plan in order to “mine” the phosphorus levels in the soil over time. North Tract Cattle Operation The larger North Tract includes most of the “new” ranch activities, having no previous irrigation, and having been put to primarily silvicultural use with limited pasture prior to its acquisition by Sleepy Creek. The ranch’s more intensive uses, i.e., the unloading corrals and the slaughter house, are located on the North Tract. The North Tract is 7,207 acres in size. Of that, 1,656 acres are proposed for irrigation by means of 15 center- pivot irrigation systems. In addition to the proposed irrigated pastures, the North Tract includes 2,382 acres of unirrigated improved pasture, of which approximately 10 percent is wooded. Under the proposed permit, a maximum of 6,371 cattle would be managed on the North Tract. Of that number, 3,497 cattle would be grazed on the irrigated paddocks (roughly 2.2 head of cattle per acre), and 2,374 cattle would graze on the improved pastures (up to 1.1 head of cattle per acre). The higher cattle density in the irrigated pastures can be maintained due to the higher quality grass produced as a result of irrigation. The remaining 500 cattle would be held temporarily in high-concentration corrals, either after offloading or while awaiting slaughter. On average, there will be fewer than 250 head of cattle staged in those high-concentration corrals at any one time. In the absence of irrigation, the improved pasture on the North Tract could sustain about 4,585 cattle. Nutrient Management Plan, Water Conservation Plan, and BMPs The CUP and ERP applications find much of their support in the implementation of the Nutrient Management Plan (NMP), the Water Conservation Plan, and Best Management Practices (BMPs). The NMP sets forth information designed to govern the day to day operations of the ranch. Those elements of the NMP that were the subject of substantive testimony and evidence at the hearing are discussed herein. Those elements not discussed herein are found to have been supported by Sleepy Creek’s prima facie case, without a preponderance of competent and substantial evidence to the contrary. The NMP includes a herd management plan, which describes rotational grazing and the movement of cattle from paddock to paddock, and establishes animal densities designed to maintain a balance of nutrients on the paddocks, and to prevent overgrazing. The NMP establishes fertilization practices, with the application of fertilizer based on crop tissue analysis to determine need and amount. Thus, the application of nitrogen- based fertilizer is restricted to that capable of ready uptake by the grasses and forage crops, limiting the amount of excess nitrogen that might run off of the pastures or infiltrate past the root zone. The NMP establishes operation and maintenance plans that incorporate maintenance and calibration of equipment, and management of high-use areas. The NMP requires that records be kept of, among other things, soil testing, nutrient application, herd rotation, application of irrigation water, and laboratory testing. The irrigation plan describes the manner and schedule for the application of water during each irrigation cycle. Irrigation schedules for grazed and cropped scenarios vary from pivot to pivot based primarily on soil type. The center pivots proposed for use employ high-efficiency drop irrigation heads, resulting in an 85 percent system efficiency factor, meaning that there is an expected evaporative loss of 15 percent of the water before it becomes available as water in the soil. That level of efficiency is greater than the system efficiency factor of 80 percent established in CUP A.H. section 12.5.2. Other features of the irrigation plan include the employment of an irrigation manager, installation of an on-site weather station, and cumulative tracking of rain and evapotranspiration with periodic verification of soil moisture conditions. The purpose of the water conservation practices is to avoid over application of water, limiting over-saturation and runoff from the irrigated pastures. Sleepy Creek has entered into a Notice of Intent to Implement Water Quality BMPs with the Florida Department of Agriculture and Consumer Services which is incorporated in the NMP and which requires the implementation of Best Management Practices.2/ Dr. Bottcher testified that implementation and compliance with the Water Quality Best Management Practices manual creates a presumption of compliance with water quality standards. His testimony in that regard is consistent with Department of Agriculture and Consumer Services rule 5M-11.003 (“implementation, in accordance with adopted rules, of BMPs that have been verified by the Florida Department of Environmental Protection as effective in reducing target pollutants provides a presumption of compliance with state water quality standards.”). Rotational Grazing Rotational grazing is a practice by which cattle are allowed to graze a pasture for a limited period of time, after which they are “rotated” to a different pasture. The 1,656 acres proposed for irrigation on the North Tract are to be divided into 15 center-pivot pastures. Each individual pasture will have 10 fenced paddocks. The 611 acres of irrigated pasture on the East Tract are divided into 6 center-pivot pastures. The outer fence for each irrigated pasture is to be a permanent “hard” fence. Separating the internal paddocks will be electric fences that can be lowered to allow cattle to move from paddock to paddock, and then raised after they have moved to the new paddock. The NMP for the North Tract provides that cattle are to be brought into individual irrigated pastures as a single herd of approximately 190 cattle and placed into one of the ten paddocks. They will be moved every one to three days to a new paddock, based upon growing conditions and the reduction in grass height resulting from grazing. In this way, the cattle are rotated within the irrigated pasture, with each paddock being used for one to three days, and then rested until each of the other paddocks have been used, whereupon it will again be used in the rotation. The East Tract NMP generally provides for rotation based on the height of the pasture grasses, but is designed to provide a uniform average of cattle per acre per year. Due to the desire to “mine” phosphorus deposited during the years of operation of the East Tract as a sod farm, the density of cattle on the irrigated East Tract pastures is about 30 percent less than that proposed for the North Tract. The East Tract NMP calls for a routine pasture rest period of 15 to 30 days. Unlike dairy farm pastures, where dairy cows traverse a fixed path to the milking barn several times a day, there will be minimal “travel lanes” within the pastures or between paddocks. There will be no travel lanes through wetlands. If nitrogen-based fertilizer is needed, based upon tissue analysis of the grass, fertilizer is proposed for application immediately after a paddock is vacated by the herd. By so doing, the grass within each paddock will have a sufficient period to grow and “flush up” without grazing or traffic, which results in a high—quality grass when the cattle come back around to feed. Sleepy Creek proposes that rotational grazing is to be practiced on improved pastures and irrigated pastures alike. The rotational practices on the improved East Tract and North Tract pastures are generally similar to those practiced on the irrigated pastures. The paddocks will have permanent watering troughs, with one trough serving two adjacent paddocks. The troughs will be raised to prevent “boggy areas” from forming around the trough. Since the area around the troughs will be of a higher use, Sleepy Creek proposes to periodically remove accumulated manure, and re-grade if necessary. Other cattle support items, including feed bunkers and shade structures are portable and can be moved as conditions demand. Forage Crop Production The primary forage crop on the irrigated pastures is to be Bermuda grass. Bermuda grass or other grass types tolerant of drier conditions will be used in unirrigated pastures. During the winter, when Bermuda grass stops growing, Sleepy Creek will overseed the North Tract pastures with ryegrass or other winter crops. Due to the limitation on irrigation water, the East Tract NMP calls for no over-seeding for production of winter crops. Crops do not grow uniformly during the course of a year. Rather, there are periods during which there are excess crops, and periods during which the crops are not growing enough to keep up with the needs of the cattle. During periods of excess, Sleepy Creek will cut those crops and store them as haylage to be fed to the cattle during lower growth periods. The North Tract management plan allows Sleepy Creek to dedicate one or more irrigated pastures for the exclusive production of haylage. If that option is used, cattle numbers will be reduced in proportion to the number of pastures dedicated to haylage production. As a result of the limit on irrigation, the East Tract NMP does not recommend growing supplemental feed on dedicated irrigation pivot pastures. Direct Wetland Impacts Approximately 100 acres proposed for irrigation are wetlands or wetland buffer. Those areas are predominantly isolated wetlands, though some have surface water connections to Mill Creek, a water of the state. Trees will be cut in the wetlands to allow the pivot to pass overhead. Tree cutting is an exempt agricultural activity that does not require a permit. There was no persuasive evidence that cutting trees will alter the fundamental benefit of the wetlands or damage water resources of the District. The wetlands and wetland buffer will be subject to the same watering and fertigation regimen as the irrigated pastures. The application of water to wetlands, done concurrently with the application of water to the pastures, will occur during periods in which the pasture soils are dry. The incidental application of water to the wetlands during dry periods will serve to maintain hydration of the wetlands, which is considered to be a benefit. Fertilizers will be applied through the irrigation arms, a process known as fertigation. Petitioners asserted that the application of fertilizer onto the wetlands beneath the pivot arms could result in some adverse effects to the wetlands. However, Petitioners did not quantify to what extent the wetlands might be affected, or otherwise describe the potential effects. Fertigation of the wetlands will promote the growth of wetland plants. Nitrogen applied through fertigation will be taken up by plants, or will be subject to denitrification -- a process discussed in greater detail herein -- in the anaerobic wetland soils. The preponderance of the evidence indicated that enhanced wetland plant growth would not rise to a level of concern. Since most of the affected wetlands are isolated wetlands, there is expected to be little or no discharge of nutrients from the wetlands. Even as to those wetlands that have a surface water connection, most, if not all of the additional nitrogen applied through fertigation will be accounted for by the combined effect of plant uptake and denitrification. Larger wetland areas within an irrigated pasture will be fenced at the buffer line to prevent cattle from entering. The NMP provided a blow-up of the proposed fencing related to a larger wetland on Pivot 8. Although other figures are not to the same scale, it appears that larger wetlands associated with Pivots 1, 2, 3, and 12 will be similarly fenced. Cattle would be allowed to go into the smaller, isolated wetlands. Cattle going into wetlands do not necessarily damage the wetlands. Any damage that may occur is a function of density, duration, and the number of cattle. The only direct evidence of potential damage to wetlands was the statement that “[i]f you have 6,371 [cattle] go into a wetland, there may be impacts.” The NMP provides that pasture use will be limited to herds of approximately 190 cattle, which will be rotated from paddock to paddock every two to three days, and which will allow for “rest” periods of approximately 20 days. There will be no travel lanes through any wetland. Thus, there is no evidence to support a finding that the cattle at the density, duration, and number proposed will cause direct adverse effects to wetlands on the property. High Concentration Areas Cattle brought to the facility are to be unloaded from trucks and temporarily corralled for inspection. For that period, the cattle will be tightly confined. Cattle that have reached their slaughter weight will be temporarily held in corrals associated with the processing plant. The stormwater retention ponds used to capture and store runoff from the offloading corral and the processing plant holding corral are part of a normal and customary agricultural activity, and are not part of the applications and approvals that are at issue in this proceeding. The retention ponds associated with the high-intensity areas do not require permits because they do not exceed one acre in size or impound more than 40 acre-feet of water. Nonetheless, issues related to the retention ponds were addressed by Petitioners and Sleepy Creek, and warrant discussion here. The retention ponds are designed to capture 100 percent of the runoff and entrained nutrients from the high concentration areas for a minimum of a 24—hour/25—year storm event. If rainfall occurs in excess of the designed storm, the design is such that upon reaching capacity, only new surface water coming to the retention pond will be discharged, and not that containing high concentrations of nutrients from the initial flush of stormwater runoff. Unlike the stormwater retention berms for the pastures, which are to be constructed from the first nine inches of permeable topsoil on the property, the corral retention ponds are to be excavated to a depth of six feet which, based on soil borings in the vicinity, will leave a minimum of two to four feet of clay beneath the retention ponds. In short, the excavation will penetrate into the clay layer underlying the pond sites, but will not penetrate through that layer. The excavated clay will be used to form the side slopes of the ponds, lining the permeable surficial layer and generally making the ponds impermeable. Organic materials entering the retention ponds will form an additional seal. An organic seal is important in areas in which retention ponds are constructed in sandy soil conditions. Organic sealing is less important in this case, where clay forms the barrier preventing nutrients from entering the surficial aquifer. Although the organic material is subject to periodic removal, the clay layer will remain to provide the impermeable barrier necessary to prevent leakage from the ponds. Dr. Bottcher testified that if, during excavation of the ponds, it was found that the remaining in-situ clay layer was too thin, Sleepy Creek would implement the standard practice of bringing additional clay to the site to ensure adequate thickness of the liner. Nutrient Balance The goal of the NMP is to create a balance of nutrients being applied to and taken up from the property. Nitrogen and phosphorus are the nutrients of primary concern, and are those for which specific management standards are proposed. Nutrient inputs to the NMP consist generally of deposition of cattle manure (which includes solid manure and urine), recycling of plant material and roots from the previous growing season, and application of supplemental fertilizer. Nutrient outputs to the NMP consist generally of volatization of ammonia to the atmosphere, uptake and utilization of the nutrients by the grass and crops, weight gain of the cattle, and absorption and denitrification of the nutrients in the soil. The NMP, and the various models discussed herein, average the grass and forage crop uptake and the manure deposition to match that of a 1,013 pound animal. That average weight takes into account the fact that cattle on the property will range from calf weight of approximately 850 pounds, to slaughter weight of 1150 pounds. Nutrients that are not accounted for in the balance, e.g., those that become entrained in stormwater or that pass through the plant root zone without being taken up, are subject to runoff to surface waters or discharge to groundwater. Generally, phosphorus not taken up by crops remains immobile in the soil. Unless there is a potential for runoff to surface waters, the nutrient balance is limited by the amount of nitrogen that can be taken up by the crops. Due to the composition of the soils on the property, the high water table, and the relatively shallow confining layer, there is a potential for surface runoff. Thus, the NMP was developed using phosphorus as the limiting nutrient, which results in nutrient application being limited by the “P-index.” A total of 108 pounds of phosphorus per acre/per year can be taken up and used by the irrigated pasture grasses and forage crops. Therefore, the total number of cattle that can be supported on the irrigated pastures is that which, as a herd, will deposit an average of 108 pounds of phosphorus per year over the irrigated acreage. Therefore, Sleepy Creek has proposed a herd size and density based on calculations demonstrating that the total phosphorus contained in the waste excreted by the cattle equals the amount taken up by the crops. A herd producing 108 pounds per acre per year of phosphorus is calculated to produce 147 pounds of nitrogen per acre per year. The Bermuda grass and forage crops proposed for the irrigated fields require 420 pounds of nitrogen per acre per year. As a result of the nitrogen deficiency, additional nitrogen-based fertilizer to make up the shortfall is required to maintain the crops. Since phosphorus needs are accounted for by animal deposition, the fertilizer will have no phosphorus. The NMP requires routine soil and plant tissue tests to determine the amount of nitrogen fertilizer needed. By basing the application of nitrogen on measured rather than calculated needs, variations in inputs, including plant decomposition and atmospheric deposition, and outputs, including those affected by weather, can be accounted for, bringing the full nutrient balance into consideration. The numeric values for crop uptakes, manure deposition, and other estimates upon which the NMP was developed were based upon literature, values, and research performed and published by the University of Florida and the Natural Resource Conservation Service. Dr. Bottcher testified convincingly that the use of such values is a proven and reliable method of developing a balance for the operation of similar agricultural operations. A primary criticism of the NMP was its expressed intent to “reduce” or “minimize” the transport of nutrients to surface waters and groundwater, rather than to “negate” or “prevent” such transport. Petitioners argue that complete prevention of the transport of nutrients from the property is necessary to meet the standards necessary for issuance of the CUP and ERP. Mr. Drummond went into some detail regarding the total mass of nutrients expected to be deposited onto the ground from the cattle, exclusive of fertilizer application. In the course of his testimony, he suggested that the majority of the nutrients deposited on the land surface “are going to make it to the surficial aquifer and then be carried either to the Floridan or laterally with the groundwater flow.” However, Mr. Drummond performed no analysis on the fate of nitrogen through uptake by crops, volatization, or soil treatment, and did not quantify the infiltration of nitrogen to groundwater. Furthermore, he was not able to provide any quantifiable estimate on any effect of nutrients on Mill Creek, the Ocklawaha River, or Silver Springs. In light of the effectiveness of the nutrient balance and other elements of the NMP, along with the retention berm system that will be discussed herein, Mr. Drummond’s assessment of the nutrients that might be expected to impact water resources of the District is contrary to the greater weight of the evidence. Mr. Drummond’s testimony also runs counter to that of Dr. Kincaid, who performed a particle track analysis of the fate of water recharge from the North Tract. In short, Dr. Kincaid calculated that of the water that makes it as recharge from the North Tract to the surficial aquifer, less than one percent is expected to make its way to the upper Floridan aquifer, with that portion originating from the vicinity of Pivot 6. Recharge from the other 14 irrigated pastures was ultimately accounted for by evapotranspiration or emerged at the surface and found its way to Mill Creek. The preponderance of the competent, substantial evidence adduced at the final hearing supports the effectiveness of the NMPs for the North Tract and East Tract at managing the application and use of nutrients on the property, and minimizing the transport of nutrients to surface water and groundwater resources of the District. North Central Florida Model All of the experts involved in this proceeding agreed that the use of groundwater models is necessary to simulate what might occur below the surface of the ground. Models represent complex systems by applying data from known conditions and impacts measured over a period of years to simulate the effects of new conditions. Models are imperfect, but are the best means of predicting the effects of stresses on complex and unseen subsurface systems. The North Central Florida (NCF) model is used to simulate impacts of water withdrawals on local and regional groundwater levels and flows. The NCF model simulates the surficial aquifer, the upper Floridan aquifer, and the lower Floridan aquifer. Those aquifers are separated from one another by relatively impervious confining units. The intermediate confining unit separates the surficial aquifer from the upper Floridan aquifer. The intermediate confining unit is not present in all locations simulated by the NCF model. However, the evidence is persuasive that the intermediate confining unit is continuous at the North Tract, and serves to effectively isolate the surficial aquifer from the upper Floridan aquifer. The NCF model is not a perfect depiction of what exists under the land surface of the North Tract or elsewhere. It was, however, acknowledged by the testifying experts in this case, despite disagreements as to the extent of error inherent in the model, to be the best available tool for calculating the effects of withdrawals of water within the boundary of the model. The NCF model was developed and calibrated over a period of years, is updated routinely as data becomes available, and has undergone peer review. Aquifer Performance Tests In order to gather site-specific data regarding the characteristics of the aquifer beneath the Sleepy Creek property, a series of three aquifer performance tests (APTs) was conducted on the North Tract. The first two tests were performed by Sleepy Creek, and the third by the District. An APT serves to induce stress on the aquifer by pumping from a well at a high rate. By observing changes in groundwater levels in observation wells, which can be at varying distances from the extraction well, one can extrapolate the nature of the subsurface. In addition, well-completion reports for the various withdrawal and observation wells provide actual data regarding the composition of subsurface soils, clays, and features of the property. The APT is particularly useful in evaluating the ability of the aquifer to produce water, and in calculating the transmissivity of the aquifer. Transmissivity is a measure of the rate at which a substance passes through a medium and, as relevant to this case, measures how groundwater flows through an aquifer. The APTs demonstrated that the Floridan aquifer is capable of producing water at the rate requested. The APT drawdown contour measured in the upper Floridan aquifer was greater than that predicted from a simple run of the NCF model, but the lateral extent of the drawdown was less than predicted. The most reasonable conclusion to be drawn from the combination of greater than expected drawdown in the upper Floridan aquifer with less than expected extent is that the transmissivity of the aquifer beneath the North Tract is lower than the NCF model assumptions. The conclusion that the transmissivity of the aquifer at the North Tract is lower than previously estimated means that impacts from groundwater extraction would tend to be more vertical than horizontal, i.e., the drawdown would be greater, but would be more localized. As such, for areas of lower than estimated transmissivity, modeling would over-estimate off-site impacts from the extraction. NCF Modeling Scenarios The initial NCF modeling runs were based on an assumed withdrawal of 2.39 mgd, an earlier -- though withdrawn - - proposal. The evidence suggests that the simulated well placement for the 2.39 mgd model run was entirely on the North Tract. Thus, the results of the model based on that withdrawal have some limited relevance, especially given that the proposed CUP allows for all of the requested 1.46 mgd of water to be withdrawn from North Tract wells at the option of Sleepy Creek, but will over-predict impacts from the permitted rate of withdrawal. A factor that was suggested as causing a further over-prediction of drawdown in the 2.39 mgd model run was the decision, made at the request of the District, to exclude the input of data of additional recharge to the surficial aquifer, wetlands and surface waters from the irrigation, and the resulting diminution in soil storage capacity. Although there is some merit to the suggestion that omitting recharge made the model results “excessively conservative,” the addition of recharge to the model would not substantially alter the predicted impacts. A model run was subsequently performed based on a presumed withdrawal of 1.54 mgd, a rate that remains slightly more than, but still representative of, the requested amount of 1.46 mgd. The 1.54 mgd model run included an input for irrigation recharge. The simulated extraction points were placed on the East Tract and North Tract in the general configuration as requested in the CUP application. The NCF is designed to model the impacts of a withdrawal based upon various scenarios, identified at the hearing as Scenarios A, B, C, and D. Scenario A is the baseline condition for the NCF model, and represents the impacts of all legal users of water at their estimated actual flow rates as they existed in 1995. Scenario B is all existing users, not including the applicant, at end-of-permit allocations. Scenario C is all existing users, including the applicant, at current end-of-permit allocations. Scenario D is all permittees at full allocation, except the applicant which is modeled at the requested (i.e., new or modified) end-of-permit allocation. To simulate the effects of the CUP modification, simulations were performed on scenarios A, C, and D. In order to measure the specific impact of the modification of the CUP, the Scenario C impacts to the surficial, upper Floridan, and lower Floridan aquifers were compared with the Scenario D impacts to those aquifers. In order to measure the cumulative impact of the CUP, the Scenario A actual-use baseline condition was compared to the Scenario D condition which predicts the impacts of all permitted users, including the applicant, pumping at full end-of-permit allocations. The results of the NCF modeling indicate the following: 2.39 mgd - Specific Impact The surficial aquifer drawdown from the simulated 2.39 mgd withdrawal was less than 0.05 feet on-site and off- site, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The upper Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at between 0.30 and 0.12 feet on-site, and between 0.30 and 0.01 feet off-site. The higher off-site figures are immediately proximate to the property. The lower Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at less than 0.05 feet at all locations, and at or less than 0.02 feet within six miles of the North Tract. 2.39 mgd - Cumulative Impact The cumulative impact to the surficial aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, was less than 0.05 feet on-site, and off-site to the north and east, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The cumulative impact to the upper Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 0.4 feet to 0.8 feet over all pertinent locations. The cumulative impact to the lower Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 1.0 to 1.9 feet over all pertinent locations. The conclusion drawn by Mr. Andreyev that the predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals is supported by the evidence and accepted. 1.54 mgd - Specific Impact The NCF model runs based on the more representative 1.54 mgd withdrawal predicted a surficial aquifer drawdown of less than 0.01 feet (i.e., no drawdown contour shown) on the North Tract, and a 0.01 to 0.02 foot drawdown at the location of the East Tract. The drawdown of the upper Floridan aquifer from the CUP modification was predicted at up to 0.07 feet on the property, and generally less than 0.05 feet off-site. There were no drawdown contours at the minimum 0.01 foot level that came within 9 miles of Silver Springs. The lower Floridan aquifer drawdown from the CUP modification was predicted at less than 0.01 feet (i.e., no drawdown contour shown) at all locations. 1.54 mgd - Cumulative Impact A comparison of the cumulative drawdown contours for the 2.36 mgd model and 1.54 mgd model show there to be a significant decrease in predicted drawdowns to the surficial and upper Floridan aquifers, with the decrease in the upper Floridan aquifer drawdown being relatively substantial, i.e., from 0.5 to 0.8 feet on-site predicted for the 2.36 mgd withdrawal, to 0.4 to 0.5 feet on-site for the 1.54 mgd model. Given the small predicted individual impact of the CUP on the upper Floridan aquifer, the evidence is persuasive that the cumulative impacts are the result of other end-of-permit user withdrawals. The drawdown contour for the lower Floridan aquifer predicted by the 1.54 mgd model is almost identical to that of the 2.36 mgd model, thus supporting the conclusion that predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals. Modeled Effect on Silver Springs As a result of the relocation of the extraction wells from the East Tract to the North Tract, the NCF model run at the 1.54 mgd withdrawal rate predicted springflow at Silver Springs to increase by 0.15 cfs. The net cumulative impact in spring flow as measured from 1995 conditions to the scenario in which all legal users, including Sleepy Creek, are pumping at full capacity at their end-of-permit rates for one year3/ is roughly 35.4 cfs, which is approximately 5 percent of Silver Springs’ current flow. However, as a result of the redistribution of the Sleepy Creek withdrawal, which is, in its current iteration, a legal and permitted use, the cumulative effect of the CUP modification at issue is an increase in flow of 0.l5 cfs. Dr. Kincaid agreed that there is more of an impact to Silver Springs when the pumping allowed by the CUP is located on the East Tract than there is on the North Tract, but that the degree of difference is very small. Dr. Knight testified that effect on the flow of Silver Springs from relocating the 1.46 mgd withdrawal from the East Tract to the North Tract would be “zero.” The predicted increase of 0.15 cfs is admittedly miniscule when compared to the current Silver Springs springflow of approximately 675 cfs. However, as small as the modeled increase may be -- perhaps smaller than its “level of certainty” -- it remains the best evidence that the impact of the CUP modification to the flow of Silver Springs will be insignificant at worst, and beneficial at best. Opposition to the NCF Model Petitioners submitted considerable evidence designed to call the results generated by the District’s and Sleepy Creek’s NCF modeling into question. Karst Features A primary criticism of the validity of the NCF model was its purported inability to account for the presence of karst features, including conduits, and their effect on the results. It was Dr. Kincaid’s opinion that the NCF model assigned transmissivity values that were too high, which he attributed to the presence of karst features that are collecting flow and delivering it to springs. He asserted that, instead of assuming the presence of karst features, the model was adjusted to raise the overall capacity of the porous medium to transmit water, and thereby match the observed flows. In his opinion, the transmissivity values of the equivalent porous media were raised so much that the model can no longer be used to predict drawdowns. That alleged deficiency in the model is insufficient for two reasons. First, as previously discussed in greater detail, the preponderance of the evidence in this case supports a finding that there are no karst features in the vicinity of the North Tract that would provide preferential pathways for water flow so as to skew the results of the NCF model. Second, Dr. Kincaid, while acknowledging that the NCF model is the best available tool for predicting impacts from groundwater extraction on the aquifer, suggested that a hybrid porous media and conduit model would be a better means of predicting impacts, the development of which would take two years or more. There is no basis for the establishment of a de facto moratorium on CUP permitting while waiting for the development of a different and, in this case, unnecessary model. For the reasons set forth herein, it is found that the NCF model is sufficient to accurately and adequately predict the effects of the Sleepy Creek groundwater withdrawals on the aquifers underlying the property, and to provide reasonable assurance that the standards for such withdrawals have been met. Recharge to the Aquifer Petitioners argued that the modeling results showing little significant drawdown were dependent on the application of unrealistic values for recharge or return flow from irrigation. In a groundwater model, as in the physical world, some portion of the water extracted from the aquifer is predicted to be returned to the aquifer as recharge. If more water is applied to the land surface than is being accounted for by evaporation, plant uptake and evapotranspiration, surface runoff, and other processes, that excess water may seep down into the aquifer as recharge. Recharge serves to replenish the aquifer and offset the effects of the groundwater withdrawal. Dr. Kincaid opined that the NCF modeling performed for the CUP application assigned too much water from recharge, offsetting the model's prediction of impacts to other features. It is reasonable to assume that there is some recharge associated with both agricultural and public supply uses. However, the evidence suggests that the impact of recharge on the overall NCF model results is insignificant on the predicted impacts to Silver Springs, the issue of primary concern. Mr. Hearn ran a simulation using the NCF model in which all variables were held constant, except for recharge. The difference between the “with recharge” and “without recharge" simulations at Silver Springs was 0.002 cfs. That difference is not significant, and is not suggestive of adverse impacts on Silver Springs from the CUP modification. Dr. Kincaid testified that “the recharge offset on the property is mostly impacting the surficial aquifer,” and that “the addition of recharge in this case didn't have much of an impact on the upper Floridan aquifer system.” As such, the effect of adding recharge to the model would be as to the effect of groundwater withdrawal on wetlands or surface water bodies, and not on springs. As previously detailed, the drawdown of the surficial aquifer simulated for the 2.39 mgd “no recharge” scenario were less than 0.05 feet on-site and off-site, except for a predicted 0.07 foot drawdown to the west of the North Tract. The predicted drawdown of the surficial aquifer for the 1.54 mgd “with recharge” scenario was 0.02 feet or less. The preponderance of the evidence supports a finding that drawdowns of either degree are less than that at which adverse impacts to wetlands or surface waters would occur. Thus, issues related to the recharge or return flows from irrigation are insufficient to support a finding or conclusion that the NCF model failed to provide reasonable assurance that the standards for issuance of the CUP modification were met. External Boundaries The boundaries of the NCF model are not isolated from the rest of the physical world. Rather, groundwater flows into the modeled area from multiple directions, and out of the modeled area in multiple directions. Inflows to the model area are comprised of recharge, which is an assigned value, and includes water infiltrating and recharging the aquifer from surface waters; injection wells; upward and downward leakage from lower aquifers; and flow across the external horizontal boundaries. Outflows from the model area include evapotranspiration; discharge to surface waters, including springs and rivers; extraction from wells; upward and downward leakage from lower aquifers; and flow against the external model boundaries. Dr. Kincaid testified that flow across the external model boundary is an unknown and unverifiable quantity which increases the uncertainty in the model. He asserted that in the calibrated version of the model, there is no way to check those flows against data. His conclusion was that the inability of the NCF model to accurately account for external boundary flow made the margin of error so great as to make the model an unreliable tool with which to assess whether the withdrawal approved by the proposed CUP modification will increase or decrease drawdown at Silver Springs. The District correlates the NCF model boundaries with a much larger model developed by the United States Geological Survey, the Peninsula of Florida Model, more commonly referred to as the Mega Model, which encompasses most of the State of Florida and part of Southeast Georgia. The Mega Model provides a means to acknowledge that there are stresses outside the NCF model, and to adjust boundary conditions to account for those stresses. The NCF is one of several models that are subsets of the Mega Model, with the grids of the two models being “nested” together. The 1995 base year of the NCF model is sufficiently similar to the 1993-1994 base year of the Mega Model as to allow for a comparison of simulated drawdowns calculated by each of the models. By running a Mega Model simulation of future water use, and applying the change in that use from 1993 base year conditions, the District was able to come to a representative prediction of specific boundary conditions for the 1995 NCF base year, which were then used as the baseline for simulations of subsequent conditions. In its review of the CUP modification, the District conducted a model validation simulation to measure the accuracy of the NCF model against observed conditions, with the conditions of interest being the water flow at Silver Springs. The District ran a simulation using the best information available as to water use in the year 2010, the calculated boundary conditions, irrigation, pumping, recharge, climatic conditions, and generally “everything that we think constitutes that year.” The discharge of water at Silver Springs in 2010 was measured at 580 cfs. The discharge simulated by the NCF model was 545 cfs. Thus, the discharge predicted by the NCF model simulation was within six percent of the observed discharge. Such a result is generally considered in the modeling community to be “a home run.” Petitioners’ objections to the calculation of boundary conditions for the NCF model are insufficient to support a finding that the NCF model is not an appropriate and accurate tool for determining that reasonable assurance has been provided that the standards for issuance of the CUP modification were met. Cumulative Impact Error As part of the District’s efforts to continually refine the NCF, and in conjunction with a draft minimum flows and levels report for Silver Springs and the Silver River, the cumulative NCF model results for the period of baseline to 2010 were compared with the simulated results from the Northern District Model (NDF), a larger model that overlapped the NCF. As a result of the comparison, which yielded different results, it was discovered that the modeler had “turned off” not only the withdrawal pumps, but inputs to the aquifer from drainage wells and sinkholes as well. When those inputs were put back into the model run, and effects calculated only from withdrawals between the “pumps-off” condition and 2010 pumping conditions, the cumulative effect of the withdrawals was adjusted from a reduction in the flow at Silver Springs of 29 cfs to a reduction of between 45 and 50 cfs, an effect described as “counterintuitive.” Although that result has not undergone peer review, and remains subject to further review and comparison with the Mega Model, it was accepted by the District representative, Mr. Bartol. Petitioners seized upon the results of the comparison model run as evidence of the inaccuracy and unreliability of the NCF model. However, the error in the NCF model run was not the result of deficiencies in the model, but was a data input error. Despite the error in the estimate of the cumulative effect of all users at 2010 levels, the evidence in this case does not support a finding that the more recent estimates of specific impact from the CUP at issue were in error. NCF Model Conclusion As has been discussed herein, a model is generally the best means by which to calculate conditions and effects that cannot be directly observed. The NCF model is recognized as being the best tool available for determining the subsurface conditions of the model domain, having been calibrated over a period of years and subject to peer review. It should be recognized that the simulations run using the NCF model represent the worst—case scenario, with all permittees simultaneously drawing at their full end-of-permit allocations. There is merit to the description of that occurrence as being “very remote.” Thus, the results of the modeling represent a conservative estimate of potential drawdown and impacts. While the NCF model is subject to uncertainty, as is any method of predicting the effects of conditions that cannot be seen, the model provides reasonable assurance that the conditions simulated are representative of the conditions that will occur as a result of the withdrawals authorized by the CUP modification. Environmental Resource Permit The irrigation proposed by the CUP will result in runoff from the North Tract irrigated pastures in excess of that expected from the improved pastures, due in large measure to the diminished storage capacity of the soil. Irrigation water will be applied when the soils are dry, and capable of absorbing water not subject to evaporation or plant uptake. The irrigation water will fill the storage space that would exist without irrigation. With irrigation water taking up the capacity of the soil to hold water, soils beneath the irrigation pivots will be less capable of retaining additional moisture during storm events. Thus, there is an increased likelihood of runoff from the irrigated pastures over that expected with dry soils. The increase in runoff is expected to be relatively small, since there should be little or no irrigation needed during the normal summer wet season. The additional runoff may have increased nutrient levels due to the increased cattle density made possible by the irrigation of the pastures. The CUP has a no—impact requirement for water quality resulting from the irrigation of the improved pasture. Thus, nutrients leaving the irrigated pastures may not exceed those calculated to be leaving the existing pre-development use as improved pastures. Retention Berms The additional runoff and nutrient load is proposed to be addressed by constructing a system of retention berms, approximately 50,0004/ feet in length, which is intended to intercept, retain, and provide treatment for runoff from the irrigated pasture. The goal of the system is to ensure that post—development nutrient loading from the proposed irrigated pastures will not exceed the pre—development nutrient loading from the existing improved pastures. An ERP permit is required for the construction of the berm system, since the area needed for the construction of the berms is greater than the one acre in size, and since the berms have the capability of impounding more than 40 acre-feet of water. The berms are to be constructed by excavating the top nine inches of sandy, permeable topsoil and using that permeable soil to create the berms, which will be 1 to 2 feet in height. The water storage areas created by the excavation will have flat or horizontal bottoms, and will be very shallow with the capacity to retain approximately a foot of water. The berms will be planted with pasture grasses after construction to provide vegetative cover. The retention berm system is proposed to be built in segments, with the segment designed to capture runoff from a particular center pivot pasture to be constructed prior to the commencement of irrigation from that center pivot. A continuous clay layer underlies the areas in which the berms are to be constructed. The clay layer varies from 18 to 36 inches below the ground surface, with at least one location being as much as five feet below the ground surface. As such, after nine inches of soil is scraped away to create the water retention area and construct the berm, there will remain a layer of permeable sandy material above the clay. The berms are to be constructed at least 25 feet landward of any jurisdictional wetland, creating a “safe upland line.” Thus, the construction, operation, and maintenance of the retention berms and redistribution swales will result in no direct impacts to jurisdictional wetlands or other surface waters. There will be no agricultural activities, e.g., tilling, planting, or mowing, within the 25-foot buffers, and the buffers will be allowed to establish with native vegetation to provide additional protection for downgradient wetlands. As stormwater runoff flows from the irrigated pastures, it may, in places, create concentrated flow ways. Redistribution swales will be built in those areas to spread any remaining overland flow of water and reestablish sheet flow to the retention berm system. At any point at which water may overtop a berm, the berm will be hardened with rip—rap to insure its integrity. The berms are designed to intercept and collect overland flow from the pastures and temporarily store it behind the berms, regaining the soil storage volume lost through irrigation. A portion of the runoff intercepted by the berm system will evaporate. The majority will infiltrate either through the berm, or vertically into the subsurface soils beneath it. When the surficial soils become saturated, further vertical movement will be stopped by the impermeable clay layer underlying the site. The runoff water will then move horizontally until it reemerges into downstream wetland systems. Thus, the berm system is not expected to have a measurable impact on the hydroperiod of the wetlands on the North Tract. Phosphorus Removal Phosphorus tends to get “tied up” in soil as it moves through it. Phosphorus reduction occurs easily in permeable soil systems because it is removed from the water through a chemical absorption process that is not dependent on the environment of the soil. As the soils in the retention areas and berms go through drying cycles, the absorption capacity is regenerated. Thus, the retention system will effectively account for any increase in phosphorus resulting from the increased cattle density allowed by the irrigation such that there is expected to be no increase in phosphorus levels beyond the berm. Nitrogen Removal When manure is deposited on the ground, primarily as high pH urine, the urea is quickly converted to ammonia, which experiences a loss of 40 to 50 percent of the nitrogen to volatization. Soil conditions during dry weather conditions are generally aerobic. Remaining ammonia in the manure is converted by aerobic bacteria in the soil to nitrates and nitrites. Converted nitrates and nitrites from manure, along with nitrogen from fertilizer, is readily available for uptake as food by plants, including grasses and forage crops. Nitrates and nitrites are mobile in water. Therefore, during rain events of sufficient intensity to create runoff, the nitrogen can be transported downstream towards wetlands and other receiving waters, or percolate downward through the soil until blocked by an impervious barrier. During storm events, the soils above the clay confining layer and the lower parts of the pervious berms become saturated. Those saturated soils are drained of oxygen and become anaerobic. When nitrates and nitrites encounter saturated conditions, they provide food for anaerobic bacteria that exist in those conditions. The bacteria convert nitrates and nitrites to elemental nitrogen, which has no adverse impact on surface waters or groundwater. That process, known as denitrification, is enhanced in the presence of organic material. The soils from which the berms are constructed have a considerable organic component. In addition to the denitrification that occurs in the saturated conditions in and underlying the berms, remaining nitrogen compounds that reemerge into the downstream wetlands are likely to encounter organic wetland-type soil conditions. Organic wetland soils are anaerobic in nature, and will result in further, almost immediate denitrification of the nitrates and nitrites in the emerging water. Calculation of Volume - BMPTRAINS Model The calculation of the volume necessary to capture and store excess runoff from the irrigated pastures was performed by Dr. Wanielista using the BMPTRAINS model. BMPTRAINS is a simple, easy to use spreadsheet model. Its ease of use does not suggest that it is less than reliable. The model has been used as a method of calculating storage volumes in many conditions over a period of more than 40 years. The model was used to calculate the storage volumes necessary to provide storage and treatment of runoff from fifteen “basins” that had a control or a Best Management Practice associated with them. All of the basins were calculated as being underlain by soils in poorly-drained hydrologic soil Group D, except for the basin in the vicinity of Pivot 6, which is underlain by the more well-drained soil Group A. The model assumed about percent of the property to have soil Group A soils, an assumption that is supported by the evidence. Soil moisture conditions on the property were calculated by application of data regarding rainfall events and times, the irrigation schedule, and the amount of irrigation water projected for use over a year. The soil moisture condition was used to determine the amount of water that could be stored in the on-site soils, known as the storage coefficient. Once the storage coefficient was determined, that data was used to calculate the amount of water that would be expected to run off of the North Tract, known as the curve number. The curve number is adjusted by the extent to which the storage within a soil column is filled by the application of irrigation water, making it unable to store additional rainfall. As soil storage goes down, the curve number goes up. Thus, a curve number that approaches 100 means that more water is predicted to run off. Conversely, a lower curve number means that less water is predicted to run off. The pre-development curve number for the North Tract was based on the property being an unirrigated, poor grass area. A post-development curve number was assigned to the property that reflected a wet condition representative of the irrigated soils beneath the pivots. In calculating the storage volume necessary to handle runoff from the basins, the wet condition curve number was adjusted based on the fact that there is a mixture of irrigated and unirrigated general pasture within each basin to be served by a segment of the retention berm system, and by the estimated 15 percent of the time that the irrigation areas would be in a drier condition. In addition, the number was adjusted to reflect the 8 to 10 inches of additional evapotranspiration that occurs as a result of irrigation. The BMPTRAINS model was based on average annual nutrient-loading conditions, with water quality data collected at a suitable point within Reach 22, the receiving waterbody. The effects of nutrients from the irrigated pastures on receiving waterbodies is, in terms of the model, best represented by average annual conditions, rather than a single highest-observed nutrient value. Pre-development loading figures were based on the existing use of the property as unirrigated general pasture. The pre-development phosphorus loading figure was calculated at an average event mean concentration (EMC) of 0.421 milligrams per liter (mg/l). The post—condition phosphorus loading figure was calculated at an EMC of 0.621 mg/l. Therefore, in order to achieve pre-development levels of phosphorus, treatment to achieve a reduction in phosphorus of approximately 36 percent was determined to be necessary. The pre-development nitrogen loading figure was calculated at an EMC of 2.6 mg/l. The post—condition nitrogen loading figure was calculated at an EMC of 3.3 mg/l. Therefore, in order to achieve pre-development levels of nitrogen, treatment to achieve a reduction in nitrogen of approximately 25 percent was determined to be necessary. The limiting value for the design of the retention berms is phosphorus. To achieve post-development concentrations that are equal to or less than pre-development concentrations, the treatment volume of the berm system must be sufficient to allow for the removal of 36 percent of the nutrients in water being retained and treated behind the berms, which represents the necessary percentage of phosphorus. In order to achieve the 36 percent reduction required for phosphorus, the retention berm system must be capable of retaining approximately 38 acre—feet of water from the 15 basins. In order to achieve that retention volume, a berm length of approximately 50,000 linear feet was determined to be necessary, with an average depth of retention behind the berms of one foot. The proposed length of the berms is sufficient to retain the requisite volume of water to achieve a reduction in phosphorus of 36 percent. Thus, the post-development/irrigation levels of phosphorus from runoff are expected to be no greater than pre-development/general pasture levels of phosphorus from runoff. By basing the berm length and volume on that necessary for the treatment of phosphorus, there will be storage volume that is greater than required for a 25 percent reduction in nitrogen. Thus, the post-development/irrigation levels of nitrogen from runoff are expected to be less than pre- development/general pasture levels of nitrogen from runoff. Mr. Drummond admitted that the design of the retention berms “shows there is some reduction, potentially, but it's not going to totally clean up the nutrients.” Such a total clean-up is not required. Rather, it is sufficient that there is nutrient removal to pre-development levels, so that there is no additional pollutant loading from the permitted activities. Reasonable assurance that such additional loading is not expected to occur was provided. Despite Mr. Drummond’s criticism of the BMPTRAINS model, he did not quantify nutrient loading on the North Tract, and was unable to determine whether post-development concentrations of nutrients would increase over pre-development levels. As such, there was insufficient evidence to counter the results of the BMPTRAINS modeling. Watershed Assessment Model In order to further assess potential water quantity and water quality impacts to surface water bodies, and to confirm stormwater retention area and volume necessary to meet pre-development conditions, Sleepy Creek utilized the Watershed Assessment Model (WAM). The WAM is a peer-reviewed model that is widely accepted by national, state, and local regulatory entities. The WAM was designed to simulate water balance and nutrient impacts of varying land uses. It was used in this case to simulate and provide a quantitative measure of the anticipated impacts of irrigation on receiving water bodies, including Mill Creek, Daisy Creek, the Ocklawaha River, and Silver Springs. Inputs to the model include land conditions, soil conditions, rain and climate conditions, and water conveyance systems found on the property. In order to calculate the extent to which nutrients applied to the land surface might affect receiving waters, a time series of surface water and groundwater flow is “routed” through the modeled watershed and to the various outlets from the system, all of which have assimilation algorithms that represent the types of nutrient uptakes expected to occur as water goes through the system. Simulations were performed on the North Tract in its condition prior to acquisition by Sleepy Creek, in its current “exempted improved pasture condition,” and in its proposed “post—development” pivot-irrigation condition. The simulations assessed impacts of the site conditions on surface waters at the point at which they leave the property and discharge to Mill Creek, and at the point where Mill Creek merges into the Ocklawaha River. The baseline condition for measuring changes in nutrient concentrations was determined to be that lawfully existing at the time the application was made. Had there been any suggestion of illegality or impropriety in Sleepy Creek’s actions in clearing the timber and creating improved pasture, a different baseline might be warranted. However, no such illegality or impropriety was shown, and the SJRWMD rules create no procedure for “looking back” to previous land uses and conditions that were legally changed. Thus, the “exempted improved pasture condition” nutrient levels are appropriate for comparison with irrigated pasture nutrient levels. The WAM simulations indicated that nitrogen resulting from the irrigation of the North Tract pastures would be reduced at the outflow to Mill Creek at the Reach 22 stream segment from improved pasture levels by 1.7 percent in pounds per year, and by 0.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 1.3 percent in pounds per year, and 0.5 percent in milligrams per liter of water. These levels are small, but nonetheless support a finding that the berm system is effective in reducing nitrogen from the North Tract. Furthermore, the WAM simulations showed levels of nitrogen from the irrigated pasture after the construction of the retention berms to be reduced from that present in the pre- development condition, a conclusion consistent with that derived from the BMPTRAINS model. The WAM simulations indicated that phosphorus from the irrigated North Tract pastures, measured at the outflow to Mill Creek at the Reach 22 stream segment, would be reduced from improved pasture levels by 3.7 percent in pounds per year, and by 2.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 2.5 percent in pounds per year, and 1.6 percent in milligrams per liter of water. Those levels are, again, small, but supportive of a finding of no impact from the permitted activities. The WAM simulations showed phosphorus in the Ocklawaha River at the Eureka Station after the construction of the retention berms to be slightly greater than those simulated for the pre-development condition (0.00008 mg/l) -- the only calculated increase. That level is beyond miniscule, with impacts properly characterized as “non- measurable” and “non-detectable.” In any event, total phosphorus remains well below Florida’s nutrient standards. The WAM simulations were conducted based on all of the 15 pivots operating simultaneously at full capacity. That amount is greater than what is allowed under the permit. Thus, according to Dr. Bottcher, the predicted loads are higher than those that would be generated by the permitted allocation, making his estimates “very conservative.” Dr. Bottcher’s testimony is credited. During the course of the final hearing, the accuracy of the model results was questioned based on inaccuracies in rainfall inputs due to the five-mile distance of the property from the nearest rain station. Dr. Bottcher admitted that given the dynamics of summer convection storms, confidence that the rain station rainfall measurements represent specific conditions on the North Tract is limited. However, it remains the best data available. Furthermore, Dr. Bottcher testified that even if specific data points simulated by the model differ from that recorded at the rain station, that same error carries through each of the various scenarios. Thus, for the comparative purpose of the model, the errors get “washed out.” Other testimony regarding purported inaccuracies in the WAM simulations and report were explained as being the result of errors in the parameters used to run alternative simulations or analyze Sleepy Creek’s simulations, including use of soil types that are not representative of the North Tract, and a misunderstanding of dry weight/wet weight loading rates. There was agreement among witnesses that the WAM is regarded, among individuals with expertise in modeling, as an effective tool, and was the appropriate model for use in the ERP application that is the subject of this proceeding. As a result, the undersigned accepts the WAM simulations as being representative of comparative nutrient impacts on receiving surface water bodies resulting from irrigation of the North Tract. The WAM confirmed that the proposed retention berm system will be sufficient to treat additional nutrients that may result from irrigation of the pastures, and supports a finding of reasonable assurance that water quality criteria will be met. With regard to the East Tract, the WAM simulations showed that there would be reductions in nitrogen and phosphorus loading to Daisy Creek from the conversion of the property to irrigated pasture. Those simulations were also conservative because they assumed the maximum number of cattle allowed by the nutrient balance, and did not assume the 30 percent reduction in the number of cattle under the NMP so as to allow existing elevated levels of phosphorus in the soil from the sod farm to be “mined” by vegetation. Pivot 6 The evidence in this case suggests that, unlike the majority of the North Tract, a small area on the western side of the North Tract drains to the west and north. Irrigation Pivot is within that area. Dr. Harper noted that there are some soils in hydrologic soil Group A in the vicinity of Pivot 6 that reflect soils with a deeper water table where rainfall would be expected to infiltrate into the ground. Dr. Kincaid’s particle track analysis suggested that recharge to the surficial aquifer ultimately discharges to Mill Creek, except for recharge at Pivot 11, which is accounted for by evapotranspiration, and recharge at Pivot 6. Dr. Kincaid concluded that approximately 1 percent of the recharge to the surficial aquifer beneath the North Tract found its way into the upper Floridan aquifer. Those particle tracks originated only on the far western side of the property, and implicated only Pivot 6, which is indicative of the flow divide in the Floridan aquifer. Of the 1 percent of particle tracks entering the Floridan aquifer, some ultimately discharged at the St. John’s River, the Ocklawaha River, or Mill Creek. Dr. Kincaid opined, however, that most ultimately found their way to Silver Springs. Given the previous finding that the Floridan aquifer beneath the property is within the Silver Springs springshed for less than a majority of the time, it is found that a correspondingly small fraction of the less than 1 percent of the particle tracks originating on the North Tract, perhaps a few tenths of one percent, can reach Silver Springs. Dr. Bottcher generally agreed that some small percentage of the water from the North Tract may make it to the upper Floridan aquifer, but that amount will be very small. Furthermore, that water reaching the upper Floridan aquifer would have been subject to the protection and treatment afforded by the NMP and the ERP berms. The evidence regarding the somewhat less restrictive confinement of the aquifer around Pivot 6 is not sufficient to rebut the prima facie case that the CUP modification, coupled with the ERP, will meet the District’s permitting standards. Public Interest The primary basis upon which Sleepy Creek relies to demonstrate that the CUP is “consistent with the public interest” is that Florida's economy is highly dependent upon agricultural operations in terms of jobs and economic development, and that there is a necessity of food production. Sleepy Creek could raise cattle on the property using the agriculturally-exempt improved pastures, but the economic return on the investment would be questionable without the increased quality, quantity, and reliability of grass and forage crop production resulting from the proposed irrigation. Sleepy Creek will continue to engage in agricultural activities on its properties if the CUP modification is denied. Although a typical Florida beef operation could be maintained on the property, the investment was based upon having the revenue generation allowed by grass-fed beef production in order to realize a return on its capital investment and to optimize the economic return. If the CUP modification is denied, the existing CUP will continue to allow the extraction of 1.46 mgd for use on the East Tract. The preponderance of the evidence suggests that such a use would have greater impacts on the water levels at Silver Springs, and that the continued use of the East Tract as a less stringently-controlled sod farm would have a greater likelihood of higher nutrient levels, particularly phosphorus levels which are already elevated.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law set forth herein it is RECOMMENDED that the St. Johns River Water Management District enter a final order: approving the issuance of Consumptive Use Permit No. 2-083-91926-3 to Sleepy Creek Lands, LLC on the terms and conditions set forth in the complete Permit Application for Consumptive Uses of Water and the Consumptive Use Technical Staff Report; and approving the issuance of Environmental Resource Permit No. IND-083-130588-4 to Sleepy Creek Lands, LLC on the terms and conditions set forth in the complete Joint Application for Individual and Conceptual Environmental Resource Permit and the Individual Environmental Resource Permit Technical Staff Report. DONE AND ENTERED this 29th day of April, 2015, in Tallahassee, Leon County, Florida. S E. GARY EARLY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 29th day of April, 2015.
The Issue The issue is whether the 100 foot separation of respondents/applicants sewage treatment plant from the surface water management system is adequate.
Findings Of Fact Based upon all of the evidence, the following supplemental findings of fact are determined: Background Respondents/applicant, John D. Remington and Bolton S. Drackett (applicants), are the owners of record of approximately two thirds, or around 2,700 acres, of Keewaydin Island (Key Island), which lies just south of the mainland portion of the City of Naples, Florida. In conjunction with a planned luxury development of forty-two homes on Key Island, applicants have filed an application with respondent, South Florida Water Management District (District), seeking the issuance of a permit authorizing the construction and operation of a surface water management system (system) through which stormwater runoff from the project will be directed and controlled. Petitioner, Florida Audubon Society (FAS), has initiated this proceeding to contest the issuance of a permit. In an earlier and separate proceeding (DOAH Case No. 90-2415), applicants applied for a permit from the Department of Environmental Regulation (DER) to construct a wastewater treatment plant (plant) to serve the planned development. The permit was issued on January 2, 1990, and because all appeals by FAS in Case No. 90-2415 have been concluded, that proceeding is now final. Although the wastewater treatment plant has not yet been constructed, the parties agree that it will be situated more than one hundred feet from the surface water management system. This distance (100 feet) is the minimum amount of space allowed by District rule between the plant and system. Even so, the purpose of the remand proceeding is to determine whether that amount of separation is adequate. Thus, the factual issue here is whether the treated wastewater from the plant and filter fields will enter the surface water management system and cause a violation of applicable water quality standards and other relevant District criteria. In support of their respective positions on this issue, the parties have presented the testimony of a number of experts. In resolving the conflict in their testimony, the undersigned has accepted the more credible and persuasive testimony which is embodied in the findings below. A Brief Description of the Development and System The proposed development and surface water management system were described in detail in the prior recommended order entered in this case. For purposes of this Supplemental Recommended Order, it need only be noted that Key Island now has a lodge, guest quarters and recreation facilities, all presently served by septic tanks. Access to the island is provided by motor launch from an existing shore station. Subaqueous utility crossings from the mainland provide electric power and potable water to the island. The planned development includes the construction of forty-two large luxury homes and an expansion of the lodge facilities to accommodate the needs of the new residents. The homes will be built in phases with approximately ten to be built in the first year. The entire project may take as long as seven or eight years to complete. The proposed surface water management system was designed to handle a seventy-five residential unit development. However, by virtue of a reduction in size imposed by the City of Naples, the project has been reduced to forty-two homes. Even so, the capacity of the system has not been downsized. Therefore, the system as designed will more than accommodate all proposed development on the island. The development area has been divided into seven surface water management basins based upon seven existing natural water sheds on the upland portion of the project. Each basin will have a system of inlets, culverts and swales which will direct runoff to control structures. The dry swales are approximately one foot deep and five to ten feet wide and run parallel on both sides of the cart paths that link the various portions of the project. The cart paths, which will be at an elevation of 5.5 feet above mean sea level (NGVD), will have culverts running underneath to aid in maintaining the natural flow of water and limit impounding of water. The swale bottoms are designed to be one foot below the cart path elevation, or at 4.5 feet NGVD, and will be dry, except during significant rain events, because they are designed so that the bottom of the swale is at least one foot above the average wet season water table. Both the cart paths and swale system utilize a design system that is common to residential developments. Once the water reaches a specified height, it goes over the control structure and is discharged downstream into spreader swales from which the water is dispersed into either interior, low wetland areas or into two artificial lakes (7.3 and 1.0 acres in size) created for wet detention. Basins one, two, three, four and seven are designed to treat water quality by the dry detention method, that is, by the unlined swales that parallel cart paths, while water quality is accomplished in basins five and six by best management practices and wet retention, that is, the two artificial lakes. The Wastewater Treatment Plant The DER permit was issued on January 2, 1990, and carries an expiration date of January 2, 1995. It authorizes applicants to: construct a 0.035 MGD extended aeration process wastewater treatment plant with reclaimed water to dual absorption fields located at the project site as depicted on Wilson, Miller, Barton, Soll & Peek, Inc. design drawings, project number 6270, sheets 1 thru 5 of 5, dated March 20, 1989, revised October 16, 1989 and received October 19, 1989. The design drawings were submitted in support of construction application, engineering report, hydrologeolic characteristics and hydraulic modeling for effluent disposal report and related documents, dated March 20, 1989. The hydraulic capacity of the plant is limited to 0.030 MGD based on the reclaimed water disposal system. The collection system shall not exceed the 0.030 MGD hydraulic capacity as well. The wastewater treatment plant is designed to meet all DER water quality, health and safety standards. For example, the plant must achieve 90% removal of biological oxygen demand (BOD) and 90% removal of total suspended solids from the raw wastewater, or effluent levels below 20 parts per million for BOD and 10 parts per million suspended solids, whichever is more stringent. The plant must also have twenty-four hour detention in the aeration chamber and four hours detention in the clarifer. Further, a chlorine chamber contact time of fifteen minutes is required. In addition, DER has issued the permit with certain specific conditions. Among others, these include standards as to effluent chlorine residuals, the requirement that a professional engineer inspect the construction, operation requirements, sampling schedules, defined perameter levels, and the establishment of a hydraulic plant load (permitted maximum daily flow) at 30,000 gallons per day. By issuing the permit, DER has concluded that up to 30,000 gallons per day of sewage effluent can be treated and disposed of by the plant filter fields without violation of applicable DER water quality, health and safety standards. The wastewater treatment plant will be located on a centralized utility site within basin seven of the system. There are also gravity sand filters and a drainfield effluent disposal system located in basin six, which is the northeastern corner of the project. The plant will provide a high degree of treatment and disinfection for the effluent before it is discharged to the filter field. The filtered (treated) effluent will flow by gravity main to the filter fields located in an adjacent basin. Two filter fields will be used in disposing of the treated wastewater effluent. Constructed as sand mounds at a grade level of two or three feet above the existing island elevation, each filter will have dimensions of twenty feet wide and four hundred feet long. The filter fields will be constructed as a bed of gravel wrapped in filter cloth and placed within a mound of soil. A perforated four-inch pipe will be installed within the gravel bed at 5.5 feet NGVD to distribute the effluent through the filter beds. The effluent will then percolate downward and laterally away from the bed and into the groundwater table. At that point, the effluent will become indistinguishable from the groundwater Because the total daily flow will be pumped alternately into one part of the two sections of the drainfield, this allows one filter field to "rest" for a seven-day period during the use of the other filter field, thereby avoiding saturation. Therefore, the average theoretical maximum input into a filter field over a one year period at the plant's maximum capacity is 15,000 gallons per day. The plant was designed and permitted for maximum daily flows at all times of the year. However, the actual operating conditions will reflect significantly less flows due to the seasonality of the population and occupancy levels. More specifically, the plant was designed and permitted for seventy- five dwelling units and ancillary uses with an estimated maximum design flow of 28,450 gallons per day. The approved planned development will contain only forty-two dwelling units and ancillary uses with a maximum design flow of 21,200 gallons per day. Therefore, the permitted plant will treat the wastewater to a higher level due to the reserve capacity, and the plant will rarely be used at over fifty percent of its available capacity. Revised projected wastewater flows will range from daily loads of 2,325 gallons per day during the months of August and September to a high of 15,137 gallons per day during the month of February. This projected usage is consistent with historical occupancy and usage trends in the Naples area which show that occupancy of homes is at its peak during the dry season (the cooler winter months) and substantially lower during the wet season (the hot summer months). Applicants' projected wastewater flows are found to be reasonable and are hereby accepted. In making this finding, the undersigned has rejected the contention by FAS that the daily wastewater flows will be higher than that projected by the applicants and the plant will operate at maximum capacity for sustained periods of time. The system plans reflect that there will be swales within basin six located between one hundred ten and one hundred twenty feet to the west of the filter fields. These swales run parallel along a cart path and flow to the north discharging into an artificial lake at the north end of the project. The swales in this basin have a bottom elevation of 4.5 feet NGVD and decrease to an elevation of 3.5 feet NGVD at the point of discharge into the artificial lake. Adequacy of Separation Between Plant and System Rule 40E-4.091, Florida Administrative Code, adopts and incorporates by reference a document known as the "Basis for Review for Surface Water Management Permit Applications within the South Florida Water Management District - September 1989" (Basis for Review). Section 3.2.2.8 of the Basis for Review reads as follows: Sewage treatment percolation ponds. Above ground pond dikes shall not be within 200 feet of water bodies or 100 feet of dry detention/ detention areas. Additional calculations by the applicant may be necessary in unusual cases requiring deviations from these dimensions. The purpose of the above section is to provide adequate separation between above-ground percolation ponds and surface water management systems in case the percolation pond dike fails. For example, above grade percolation ponds contain large volumes of sewage treatment plant effluent. If a pond dike should fail, a large portion of effluent would be quickly released into the adjacent ground. The minimum 100-foot separation is designed to provide adequate distance for percolation into the ground prior to infiltrating the surface water management system. However, filter fields contain lesser volumes of effluent than do percolation ponds, and should a filter field fail, the effluent will trickle out the side of the field with a much lower rate of effluent release than from a failed pond dike. In accordance with the District rule, applicants have proposed to locate the surface water management system more than one hundred feet from the wastewater treatment plant and filtration beds. Even though the rule standards have been met, the purpose of this remand proceeding is to determine whether that amount of separation is adequate to prevent adverse impacts to the water quantity and water quality functions of the system from the operation and location of the filter fields. The Computer Models As a part of their application filed with DER in 1989, applicants' witness Missimer prepared and submitted a report known as "Hydrogeologic Characteristics and Hydraulic Modeling for Effluent Disposal at Keewaydin Club". The report was based on a computer model known as "Modflow" and was designed to show the increase in elevation of the water table for a loading rate of 30,000 gallons per day alternating between the two filtration beds. The purpose of the modeling analysis filed with DER was to investigate whether the plant would continue to discharge effluent to the drainfields under the most extreme conditions. The model demonstrated that the effluent discharge would not be impaired even under conditions that are beyond any reasonable or probable operating conditions. After reviewing the model, DER accepted those results and issued a permit. Utilizing in large part the underlying assumptions and parameters of the Missimer model, and without performing any independent field evaluation on the site, FAS witness Chin ran the model to investigate the impact of the operation of the plant on the system. Because the model used by Dr. Chin was not constructed for the design of a surface water management system, but rather was constructed for the purpose of designing an adsorption field, without modification it provided a more than worst case scenario of impacts associated with the operation of a plant. In this case, Dr. Chin utilized the ultra- conservative assumptions used in designing the adsorption field and made no revisions to the model. Thus, it is found that the model as used by Dr. Chin, and any conclusions drawn from the model alone, are not a sufficient or reasonable basis for evaluating the impact of the plant on the system. The model used by Dr. Chin is not representative of the natural occurring conditions on the island or the reasonably expected plant flow rates. Moreover, in developing the worst case scenario, as opposed to reasonable expectations, both the Chin and Missimer models incorporated the simultaneous occurrence of certain conservative assumptions including an impermeable flow boundary, a year round wet season water table elevation, a conservative rate of transmissivity, and a constant rate of evapotranspiration. The use of these assumptions caused the model output to grossly overstate the effects of the plant on the system in the following manner. First, by assuming a flow barrier on the island, the model had the effect of overestimating the height of the groundwater mound from operation of the plant than would occur if no boundary were used. Second, the assumption of a year-round wet season groundwater level is unrealistic since groundwater levels fluctuate seasonally, receding to near zero NGVD on the island during the dry season. Thus, the model overestimated the height of the groundwater level. Further, by using only the upper ten feet of the water table aquifer in calculating the rate of transmissivity, the model incorporated a much lower rate than would be attained had the entire thickness (74 feet) of the aquifer been used. This also resulted in an over-estimation in the height of the mound from the operation of the plant. Finally, by assuming a constant rate of evapotranspiration, the model "grossly exaggerated" the impact to the groundwater level from operation of the plant. In reality, as the water table increases, the loss of water from evapotranspiration increases significantly and constitutes a major output of a water budget. Besides the foregoing assumptions, the Chin model also assumed a continuous loading rate of 30,000 gallons per day for a period of up to one year. While the District should properly consider the permitted flow rate of the plant in evaluating a worst case of potential impact, there was no evidence substantiating any likelihood of the plant actually producing 30,000 gallons per day for 365 consecutive days in conjunction with all other conservative assumptions discussed above. The more reasonable and accepted method of analyzing the impact of plant flows is to examine the peak month's average day flow over a six-month period. As noted earlier, for the proposed forty-two units, the peak day flow is estimated to be approximately 21,200 gallons per day. Therefore, it is highly probable that actual flow rates will be much lower than the maximum plant capacity of 30,000 gallons per day. By failing to use the more reasonable and realistic reduced flow rates, the Chin model overestimated the elevation of the groundwater level from the operation of the plant. In contrast, the Missimer analysis demonstrates that it is extremely unlikely that the plant output will ever elevate groundwater to the extent that it would reach the system swales by either surface water or groundwater flow. The foregoing modeling assessments, including the criticisms of the Chin model, were concurred in by the District expert. Water Quantity Impacts There is no credible evidence to support a finding that the operation of the plant will adversely impact the ability of the system to provide adequate flood protection and drainage. Indeed, the more credible evidence shows that an alteration of existing drainage patterns will not occur by virtue of the operation of the plant, and the post-development discharge rates will not exceed the pre-development discharge rates. Therefore, the undersigned's previous finding that applicants have provided reasonable assurance that the the system provides adequate protection and drainage is not altered after considering the operation and location of the plant. There is insufficient credible evidence to support a finding that the plant's operation will adversely impact the system functions in such a way as to cause adverse water quantity impacts on receiving waters and adjacent lands. Indeed, the post-development discharge rate approximates the pre-development discharge rate on receiving waters, the ultimate receiving water body (the Gulf of Mexico) has an infinite capacity to receive water, and there are no adjacent lands subject to flooding from discharge of the system regardless of whether there is any impact of the plant on the system. There is no credible evidence to support a finding that the plant will cause the system to have an adverse impact on surface and groundwater levels and flows. Rather, the more persuasive evidence shows that the plant's operation will not result in groundwater elevation in the area of the system that would cause the impoundment of water or prevent the percolation of water into the soil. In addition, the overflow levels for control structures will operate as designed to insure against over-drainage or flooding. Finally, the operation of the filter fields will not cause adverse impacts on surface and groundwater levels and flows. Water Quality Impacts The operation of the plant will not impair the water quality functions of the system. This is because the swales will continue to detain the first flush of run-off allowing the majority of the suspended solids and other pollutants to settle out regardless of the operation of the plant. Further, in the unlikely event the treated wastewater effluent reached the system, it would be indistinguishable from the stormwater or rainfall due to the high level of treatment from the plant, the filter fields and dilution from groundwater and rainfall. The operation of the plant will not cause adverse water quality impacts on the receiving waters. In making this finding, the undersigned notes initially that the plant is permitted by DER, and therefore it is assumed to comply with all DER water quality standards. Second, there is no evidence that the system will impact the operation of the plant. In the event the groundwater mixed with treated effluent resurfaces, there would be no adverse impact to the surface water quality. This is because the treated effluent from the plant exceeds state water quality standards. Once the treated effluent becomes a part of the groundwater, it is unlikely that it will resurface again in the areas of the swales, which are more than one hundred ten feet away. Indeed, in order for the groundwater with effluent to travel that distance, it would have been in the groundwater system for at least one hundred days. This period of time is more than sufficient for the denitrification and adsorption processes to remove all nutrients. Even if the worst case scenario became a reality and the groundwater reached the swale bottoms, it would only result in a wetting of the ground and would not be of sufficient quantity to create a flow of water in the swale to travel off-site impacting a receiving water. In any event, at that point, any groundwater resurfacing that distance away would no longer be effluent. Finally, during abnormal conditions, such as a hurricane or large storm event, the groundwater may rise to the surface and mix with the surface water and enter the system. However, any effluent already significantly diluted under normal circumstances would be indistinguishable from the stormwater or rainfall. Adverse Environmental Impacts There is no credible evidence that the operation of the plant filter fields will adversely impact the system in such a manner as to cause an adverse environmental impact. In so finding, the undersigned rejects the contention that the system will act as a conduit for treated effluent to travel off-site to the ponds, marsh, mangrove areas or receiving waters. The evidence shows that the design of the filter fields and high permeability of the island soils will prevent the surface flow of effluent to the system swales. The elevation of the swales above the groundwater table level will prevent the introduction of effluent into the swale system. In the unlikely event the groundwater reaches the bottom elevation of the swale, there would be no significant environmental impact because the quality of effluent would be indistinguishable from the groundwater due to the high level of treatment and dilution, and such water would still be further treated by the system before discharge to receiving bodies. The location of the plant and system will not have an adverse impact on the gopher tortoise population on the island. Rather, the system should enhance the gopher tortoise population by providing mananged land with vegetation suitable for gopher consumption. Further, the general development on the island will reduce the number of raccoons which prey on gopher eggs and young gophers. Miscellaneous During the remand hearing, FAS presented evidence concerning the impact of tides and mean sea level rise and saline lakes on the island. This evidence was essentially the same as that presented in the prior hearing and was rejected in favor of the more credible evidence presented by the applicants on this issue. Nothing was presented during the remand hearing which would alter these prior findings. During the hearing, and in response to a question by District counsel, witness Missimer agreed it would not be unreasonable to install a few monitoring wells to insure that the system is operating properly. Because this requirement is not unreasonable, will serve a valuable purpose, and has been utilized by the District as a special condition on numerous prior occasions, it should be incorporated into the permit conditions. Even though the evidence clearly shows that seasonal tidal fluctuations would not have an adverse impact on the functioning of the system, if such a tidal incursion were to occur, the placement of a check valve device on the water control structures would prevent sea water from flowing back into the system. Such a device would be a minor addition to the system, would not otherwise affect its design, and if deemed necessary by the District, should be incorporated into the permit conditions. Prior to hearing, the District retained the services of an outside consultant to assist it in preparation for trial. The consultant did not testify at final hearing and prepared no reports. He did make several computer runs, none of which are a part of this record. Among other things, District witness Rogers relied upon the computer runs in formulating his opinion on the issue presented on remand.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a final order be entered granting the requested permit in accordance with the agency's proposed agency action dated March 28, 1990. DONE and ENTERED this 22 day of March, 1991, in Tallahassee, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22 day of March, 1991.
The Issue The issue is whether to approve an application by Respondents, Palm Beach County (County) and The David Minkin Florida Realty Trust, Richard Thall, Robert Thall, Peter L. Briger, Paul H. Briger, and The Lester Family Investments, LP (The Briger Group), for a conceptual Environmental Resource Permit (ERP) authorizing a surface water management system to serve a mixed-use development in the City of Palm Beach Gardens known as Scripps Florida Phase II/Briger (Scripps project).
Findings Of Fact Based on the evidence presented by the parties, the following findings of fact are made: The Parties Petitioner Tsolkas resides at 822 North C Street, Lake Worth, Florida, which is approximately 16.8 miles (in a straight line) south-southeast of the project site and approximately one mile west of the Intracoastal Waterway (ICW). Among others, he expressed concerns in this case about the potential extinction of species and the impact of the proposed site on the ICW. However, other than a general interest in environmental issues, he presented no evidence to demonstrate how he is affected by the issuance of the permit. Petitioner Minaya resides at 901 North Federal Highway, Apartment A, Lake Worth, Florida, and approximately the same distance from the project site and ICW. He has the same concerns as Petitioner Tsolkas but presented no evidence to demonstrate how the project will affect his substantial interests. The County is a chartered county and a political subdivision of the state. It owns approximately 70.0 acres of the site on which the Scripps project will be located and the 193.92-acre off-site mitigation area for the project at the Pine Glades Natural Area (Pine Glades). It is a co-applicant for an ERP. The Briger Group is a co-applicant for the modified ERP and owns 611.69 acres of the project site. The original permit that is being modified was issued as conceptual approval on January 19, 1978. The District is a public corporation in the State, having been created by special act in 1949 and operating pursuant to Chapter 373, Florida Statutes. The Application On April 27, 2009, the applicants submitted an application to modify a conceptual ERP, Application No. 090427- 7, for a surface water management system to serve 681.89 acres of mixed-use development in the City of Palm Beach Gardens (City). The original permit was also issued as a conceptual approval in 1978 and has been modified conceptually on a number of occasions, most recently in 2001. The application includes 193.92 acres of off-site mitigation at Pine Glades in the northern part of the County and additional off-site mitigation through the purchase of mitigation credits at the Loxahatchee Mitigation Bank in the southern part of the County. "Conceptual approval" means "an [ERP], issued by the District Governing Board, which approves a conceptual master plan for a surface water management system or a mitigation bank." Fla. Admin. Code R. 40E-4.021(5). It constitutes final agency action and is "binding to the extent that adequate data has been made available for review by the applicant during the review process." Id. After conceptual approval is obtained, the applicants must then file an application for an ERP to construct and operate the surface water management system. Therefore, no construction will be authorized by this permit. On April 16, 2010, the District issued a Staff Report recommending approval of the requested ERP. A Revised Staff Report making minor changes and clarifications to the original proposed agency action was issued on May 4, 2010. The Project and the Site The proposed project that will be served by the surface water management system is a multi-use development on a 681-acre tract located south of Donald Ross Road and north of Hood Road in the City. The site is divided by Interstate 95 (I-95) into two wedge-shaped parcels known as the western and eastern parcels. The Florida Turnpike adjoins the western side of the western parcel. With the exception of the highways, the site is surrounded by residential development including two projects located just east of the site: Legends at the Gardens (on the northern side) and San Michele (on the southern side). A portion of the site located east of I-95 is mostly undeveloped and vegetated. However, approximately 60 acres located at the southeast corner of the site include an existing horse farm with improved and unimproved pastures. The central and southern portions of this parcel contain a number of ditches that were created prior to the 1950s. The portion of the site west of I-95 is undeveloped and vegetated, but it also includes a few mobile homes on approximately 2 acres at the southern end of the site. The upland habitats are disturbed and degraded and primarily include pine flatwoods, mixed hardwood-pine forest, hardwood hammock, and dry prairie, some of which are infested with Brazilian pepper, Australian pine, and Japanese climbing fern. There are also around 86 acres of state jurisdictional wetlands and other surface waters. Finally, the southwestern portion of the parcel located west of I-95 contains a prehistoric/archaeological site which is proposed for preservation. The County owns 70 acres of the property on the eastern parcel, while The Briger Group owns the remaining acreage. The project is anticipated to house the Scripps Research Institute, as well as ancillary institutional, commercial, and residential uses. The project received development of regional impact approval from the City on April 1, 2010, and is subject to a master plan that identifies land use districts, such as a biotech district, a town center district, residential districts, and a neighborhood-serving commercial district. The 70 acres owned by the County will be used to house the second phase of the Scripps Research Institute. It is unknown at this time whether the Scripps facility will house administrative offices, laboratory space, or some other use. The build-out schedule for the project is twenty years. Before construction can commence, the applicants will be required to obtain zoning and site plan approval from the City, authorization from both the Northern Palm Beach County Improvement District (Improvement District) and the Seacoast Utility Authority, and a permit from the County Health Department. Also, the applicants will be required to receive a construction-related modification to the ERP from the District. The Surface Water Management System In 2001, the District issued a permit to the Improvement District for conceptual approval of a surface water management system for flood protection within a 4,059.9-acre area known as Unit 2, which includes the area of the proposed project. See Respondents' Exhibit 57. Drainage from the project site is presently covered by this permit. The Improvement District's system was designed, constructed, and is being operated and maintained for stormwater treatment. The waters in that system are not considered waters of the State. The proposed project will discharge into the Improvement District's system, which is upstream of a permitted man-made control structure on the property designed to retain or detain stormwater runoff in order to provide treatment and attenuation of the stormwater. The proposed system is primarily a wet detention system consisting of three large basins: A1, B1E(East), and B1W(West). The system has been designed to provide water quality and storm water attenuation prior to overflowing to the Improvement District's Unit 2 master system. As shown in the conceptual plans, Basin B1W is located on the west side of I-95 and has a control elevation of 13.5 feet National Geodetic Vertical Datum (NGVD). Mostly residential development is anticipated in this basin with a small supporting commercial development. An existing 60-inch culvert located under I-95 will continue to connect the two wetland areas, identified as W1 and W2, that are located on both the west and east sides of I- 95, respectively. Basin B1E is located in the southeastern portion of the site and will be controlled at 13.0 feet NGVD. Anticipated development in this area will be mostly residential neighborhoods as well. Exhibit 2 of the Staff Report reflects that runoff from the out-parcels and the northern half of Hood Road will be directed into the proposed project area. Pervious and impervious assumptions were made for future Hood Road improvements and are listed in the land use table. See Respondents' Exhibit 43 at p. 3 of 26. Basin B1E will overflow into the Unit 2 master system via a control structure and outfall pipe which discharges to a wet pond located within the adjacent San Michele development to the east. Industrial and commercial development is planned in Basin A1, which is the northeastern basin. The lakes will be controlled at elevation 13.0 feet NGVD. Runoff from this basin will be directed eastward into the Improvement District's Unit 2 master system via a control structure and pipe connection into the lake within the Legends of the Gardens development to the east. The applicants submitted site grading assumptions and pervious/impervious percentages as well as stormwater modeling to demonstrate compliance with the existing master system for the overall Improvement District's Unit 2 master system. In addition, the system for this basin has been designed to accommodate inflows from approximately 50 acres of I-95 right- of-way through an existing control structure which was permitted as part of the I-95 widening project. The proposed project includes direct impacts to a total of 78.47 acres of on-site wetlands. Wetland mitigation to offset the adverse impacts includes enhancement of 7.50 acres of on-site wetlands; the purchase of 13.70 freshwater herbaceous credits at the Loxahatchee Mitigation Bank; off-site wetland and upland restoration and enhancement of 163.41 acres of wetlands; and preservation of 30.51 acres of other surface waters, or a total of 193.92 acres, at Pine Glades. The ERP Permitting Criteria In order to obtain an ERP, an applicant must satisfy the conditions for issuance set forth in Rules 40E-4.301 and 40E-4.302. Additionally, the District has adopted BOR provisions that implement the relevant portions of the rules. The conditions for issuance primarily focus on water quantity, water quality, and environmental criteria and form the basis of the District's ERP permitting program. The first step in the District's environmental review is to identify wetlands and other surface waters. On March 5, 2009, the District issued a formal determination of wetlands delineating 34 wetland areas and 4 jurisdictional surface water ditches. This determination was not timely challenged and therefore represents final agency action. That determination was used in this permit application. Water Quantity Criteria Rule 40E-4.301(1)(a) requires an applicant to provide reasonable assurances that the propose activity will not cause adverse affects to water quantity, while Rule 40E-4.301(1)(b) requires reasonable assurances that the proposed activity will not cause adverse flooding to on-site or off-site property. The BOR provides a method to calculate allowable discharge rates. The evidence is that the proposed discharge is well within the standards imposed by the rules governing water quantity impacts. There will be no on-site or off-site flooding as a consequence of the proposed project. Rule 40E-4.301(1)(c) requires reasonable assurance that there will be no adverse impacts to existing surface water storage and conveyance capabilities. The evidence supports a finding that the proposed discharge will not cause any adverse impacts. Also, the system is capable of being developed and of functioning as proposed, as required by Rule 40E-4.301(1)(i). Petitioners contended that the project poses a threat of over-draining, which will significantly affect the region directly and cumulatively. However, the project does not pose a risk of over-draining because the control elevation of the project will be maintained at a level consistent with surrounding properties and the proposed drainage rate is less than the allowable rate under the rules. Water Quality Rule 40E-4.301(1)(e) sets forth the requirements relating to water quality. Also, BOR Section 5 contains the design criteria that a project must follow regarding off-site discharges to provide reasonable assurances to satisfy the above rule. Water quality treatment will be provided in a proposed wet detention system which utilizes stormwater ponds. The evidence shows that the ponds are larger than required, thereby providing water quality treatment in excess of what is required by the BOR. All water quality standards will be met. Hazardous Waste Management Plan Petitioners contend that no hazardous waste management plan was submitted to the District. However, a plan is not required now because it would need to address the specific uses for the property, which have not yet been designated. Special Condition 31 of the permit requires that such a plan be submitted at the time an application for construction approval is filed with the District. When this is submitted, it will be reviewed to determine if there are reasonable assurances that hazardous materials, if any, will not enter the proposed project's surface water management system. Elimination and Reduction Under BOR Section 4.2.1, after the District identifies the wetlands and other surface waters, the next step is to consider elimination and reduction of impacts. However, BOR Section 4.2.1.2(b) provides that an applicant is not required to demonstrate elimination and reduction impacts when: the applicant proposes mitigation that implements all or part of a plan that provides greater ecological value and that provides greater long term ecological value than the area of wetland or other surface water to be adversely affected. In considering this provision, the District concluded, consistent with the evidence, that the quality of the wetlands which will be adversely affected by this application is low, and the mitigation proposed will provide greater long-term ecological value than the wetlands impacted. This is because the mitigation at both Pine Glades and the Loxahatchee Mitigation Bank have regional ecological value, and these sites will provide greater long-term ecological value than the impacted wetlands. Secondary Impacts Rule 40E-4.301(1)(f) requires reasonable assurance that the project will not cause adverse secondary impacts to water resources. BOR Section 4.2.7 sets forth the requirements for on-site wetlands that will be preserved and enhanced. Under that section, secondary impacts to the habitat of wetlands associated with adjacent upland activities will not be considered adverse if buffers, with a minimum width of 15 feet and an average width of 25 feet, are provided abutting the wetlands. In this case, the single wetland area being preserved is buffered in accordance with those requirements. Applicants have satisfied the requirements of the rule. Mitigation If impacts to wetlands and other surface waters will occur, then mitigation may be offered to offset the impacts to functions identified in BOR Sections 4.2 through 4.2.9. To assess the impacts and the value of mitigation, the applicants used the statewide Uniform Mitigation Assessment Method and the Wetland Rapid Assessment Procedure. Those results are found in Appendix 1 of the application and in Responses to Requests for Additional Information submitted in August 2009 and January 2010. Page 13 of the Staff Report describes the mitigation. The District also performed its own independent analysis of both the impact and mitigation. That analysis demonstrated that sufficient mitigation is available in the options identified to offset the impacts. In fact, there was a net functional gain to the environment. In order to offset 50.76 acres of wetland impacts, the applicants will provide restoration and enhancement of 139.6 acres of wetlands and 23.81 acres of uplands, and preservation of 30.51 acres of other surface waters, or a total of 193.92 acres, at Pine Glades. Mitigation at this location offsets those impacts and is appropriate because it will provide more functional gain than the amount of functional loss for the same habitat types that are being impacted. Because Pine Glades is within the same drainage basin as the impacts, and the mitigation offsets the impacts, the District is not required to consider cumulative impacts. See § 373.414(8), Fla. Stat.; Fla. Admin. Code R. 40E-4.302(1)(b). Petitioners suggested that because Pine Glades is already owned by the County and intended to be restored, by allowing the applicants to receive mitigation credit for the restoration amounts to "double dipping." However, the evidence shows that the 193 acres proposed as mitigation in the permit is site-specific; no one has ever received mitigation credit for it in the past and no one will be able to receive mitigation credit for it in the future; and The Briger Group paid $86,250.00 per functional unit to reimburse the County for the cost of the land. Mitigation credit for restoration at Pine Glades is appropriate. As compensation for impacts to a total of 26.14 acres of freshwater marsh wetlands, the applicants will mitigate off- site by purchasing 13.70 freshwater herbaceous credits at the Loxahatchee Mitigation Bank. This bank is of regional ecological significance. Mitigation at this bank offsets the impacts and is appropriate because it will offset the impacts to freshwater marsh wetlands. Drainage basins are established by District rule in BOR Figure 4.4-1. While Petitioners contended that BOR Figure 4.4-1 does not accurately identify the geographic boundaries of the South Indian River Basin, which is being used here, the District is required to follow its own rules when reviewing an ERP application. Therefore, the use of Figure 4.4-1 was appropriate to determine whether the project is located within or outside of that drainage basin. Because the Loxahatchee Mitigation Bank is not located within the same basin as the proposed impacts, it was necessary for the District to consider cumulative impacts which will be mitigated at that bank. See § 373.414(8), Fla. Stat. This means that the applicants are required to give reasonable assurances that the impacts proposed for mitigation at Loxahatchee Mitigation Bank would not result in unacceptable cumulative impacts if the regulatory precedent set by the permit were applied to all properties within the basin that have the same type of habitat as that being impacted by the project and that have potential for development. The project will be located in the South Indian River Basin. The District's cumulative impact analysis for that basin supports a finding that there is very limited potential for future wetland loss in the basin and reasonable assurances have been given that there will be no adverse cumulative impacts. See Respondents' Exhibit 60. Species Rule 40E-4.301(1)(d) requires an applicant to demonstrate that the activities will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters. This evaluation is limited to wetland-dependent species. Upland species fall outside of the District's jurisdiction. Contrary to Petitioners' assertion, the hand fern is not a wetland-dependent species. Also, the District must rely on State-listed species, and not lists prepared by federal agencies. The evidence shows that the potential for utilization of this site by wetland-dependent species is minimal, and this site does not contain preferred habitat for nesting or denning of wetland dependent listed species. Although the site does not contain preferred habitat, the habitat value currently existing on this site will be replaced with mitigation at Pine Glades and the Loxahatchee Mitigation Bank. Public Interest Test In order to obtain a conceptual approval ERP, an applicant must provide reasonable assurances that the system located in, on, or over wetlands or other surface waters will not be contrary to the public interest and will not be inconsistent with the objectives of the District. See Fla. Admin. Code R. 40E-4.302(1)(a)1.-7.; § 373.414(1), Fla. Stat. The evidence establishes that reasonable assurances were provided to demonstrate that the proposed activities will not adversely affect the public health, safety, or the welfare or property of others; that they will not adversely affect the conservation of fish and wildlife, including endangered or threatened species or their habitat; that there are no issues related to navigability or the flow of water, erosion or shoaling; that the property does not currently provide fishing, recreational values, or marine productivity and is not open to the public; that the activity will be permanent; that there is an archeological site on the property which the applicants will preserve; that the mitigation will more than fully offset the impacts; and that the value of the functions currently being performed will not be adversely affected. Petitioners offered no evidence or analysis to rebut the expert testimony offered by Respondents. After balancing all seven factors, the evidence supports a finding that the activities will not be contrary to the public interest. Florida Coastal Management Program Petitioners contend that the project is inconsistent with the Florida Coastal Management Program (FCMA), which is administered by the Department of Environmental Protection (DEP). They also assert that the District is required to coordinate its review of the application with that agency and that it failed to do so. However, the issuance of the ERP (after a demonstration that all permitting criteria have been satisfied) constitutes certification that the project is consistent with the FCMA and no coordination with DEP is necessary. Other Criteria Any other criteria not discussed herein were either satisfied by the applicants or are not relevant to the project. Petitioners' Evidence Other than very limited cross-examination of some of Respondents' witnesses, Petitioner Minaya did not present any evidence to support his allegations. Other than cross-examination of Respondents' witnesses, Petitioner Tsolkas, a lay person, testified that his standing was based on general concerns that the project would drive species (such as the hand fern) into extinction, that it would pollute waters, including the ICW, and that it would destroy habitat for other species. No competent or persuasive evidence to support these contentions was presented. Other issues raised by Mr. Tsolkas were matters beyond the District's jurisdiction and are not considered in the permitting process.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the South Florida Water Management District enter a final order granting Application No. 090427-7 with the conditions contained in the Amended Staff Report. DONE AND ENTERED this 30th day of November, 2010, in Tallahassee, Leon County, Florida. S D. R. ALEXANDER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 30th day of November, 2010.
The Issue The issues are whether to (a) issue an Environmental Resource Permit (ERP) to the Department of Transportation (DOT) and Martin County (County) authorizing construction and operation of a surface water management system to serve a project known as the Indian Street Bridge; (b) issue DOT a letter of modification of ERP No. 43-00785-S authorizing roadway and drainage modifications to the Kanner Highway/Indian Street intersection; and (c) issue DOT a letter of modification of ERP No. 43-01229-P authorizing roadway and drainage modifications to Indian Street between the intersections of Kanner Highway and Willoughby Boulevard.
Findings Of Fact Based on the evidence presented by the parties, the following findings of fact are made: The Parties Petitioner Citizens for Smart Growth, Inc., is a Florida 501(c)(3) corporation with its principal place of business in Palm City, Florida. It was formed by Odias Smith in August 2001, who serves as its president. The original directors were Kathie Smith, Odias Smith, and Craig Smith, who is the Smiths' son. The composition of the Board has never changed. According to the original Articles of Incorporation, its objectives are "preserving and enhancing the present advantages of living in Martin County (Quality of Life) for the common good, through public education, and the encouragement of reasonable and considered decision making by full disclosure of impacts and alternatives for the most appropriate use of land, water and resources." The exact number of members fluctuates from time to time. There are no dues paid by any member. At his deposition, Mr. Smith stated that no membership list exists; however, Kathie Smith stated that she currently has a list of 125 names, consisting of persons who at one time or another have made a contribution, have attended a meeting, or asked to be "kept informed of what's going on or asked to be on a mailing list or a telephone list, so they could be advised when we have meetings." No meetings have been held since 2006. Therefore, the Petitions filed in these cases have never been discussed at any meetings of the members, although Ms. Smith indicated that telephone discussions periodically occur with various individuals. Kathie Smith believes that roughly 25 percent of the members reside in a mobile home park north of the project site on Kanner Highway on the eastern side of the St. Lucie River, she does not know how many members reside on the western side of the St. Lucie River, and she is unaware of any member who resides on the South Fork of the St. Lucie River immediately adjacent to the project. Although the three Petitions allege that "seventy percent of the members . . . reside and/or recreate on the St. Lucie River," and in greater detail they allege how those members use that water body or depend on it for their livelihood, no evidence was submitted to support these allegations that 70 percent (or any other percentage of members) use or depend on the South Fork of the St. Lucie River for recreational or other activities. Petitioners Odias Smith and Cathie Smith reside in Palm City, an unincorporated community just south of Stuart in Martin County. They have opposed the construction of the new bridge since they moved to Palm City in 2001. It is fair to infer that Mr. Smith formed the corporation primarily for the purpose of opposing the bridge. Their home faces north, overlooking the South Fork of the St. Lucie River, from which it is separated by Saint Lucie Shores Drive and a narrow strip of common-ownership property. A boat dock extends from the common-ownership property into the St. Lucie River, providing 5 slips for use by the Smiths and other co-owners. The home is located three blocks or approximately 1,000 feet from the proposed western landfall of the new bridge. Due to the direction that the house faces (north) and the site of the new bridge, the surface water management system elements associated with the bridge will not be visible from their property. Mr. Smith believes, however, that when looking south through a veranda window on the second floor of his home, he will be able to see at least a part of the new bridge. From the front of their house, they now have an unobstructed view of the existing Palm City Bridge, a large structure that crosses the St. Lucie River approximately six- tenths of a mile north of their home, and which is similar in size to the new bridge now being proposed by the Applicants. The Smiths' home is more than 500 feet from the Project's right- of-way, and they do not know of any impact on its value caused by the Project. While the Smiths currently engage in walking, boating, running, fishing, and watching wildlife in the neighborhood or the South Fork of the St. Lucie River, there was no credible evidence that the Project would prevent them from doing so after the bridge and other improvements are constructed. Also, there was no evidence showing that the ERP Letter Modifications will cause them to suffer any adverse impacts. In fact, as noted below, by DOT undertaking the Project, the neighborhood will be improved through reduced flooding, improved water quality, and new swales and ponds. The County is a political subdivision of the State. It filed one of the applications at issue in this proceeding. DOT is an agency of the State and filed the three applications being contested. The District has the power and duty to exercise regulatory jurisdiction over the administration and enforcement of ERP criteria pursuant to Part IV, Chapter 373, Florida Statutes, and Title 40E of the Florida Administrative Code. The Department of Environment Protection (DEP) has delegated certain authority to the District, including the authority to authorize an applicant to use sovereign submerged lands via a public easement within the District's geographic jurisdiction. The Project Construction of a new bridge over the St. Lucie River has been studied extensively by the Applicants for over twenty years. DOT has awarded the contract and nearly all of the right-of-way has been purchased. The Project will begin as soon as the remaining permits are acquired. The Project is fully funded through the American Recovery and Reinvestment Act of 2009 and County funding. The Project is located in the County and includes 62.06 acres of roadway bridge development and 12.45 acres of sovereign submerged lands. The Project begins on the west side of the St. Lucie River on County Road 714, approximately 1,300 feet west of Mapp Road in Palm City and ends on the east side of the St. Lucie River approximately 1,400 feet east of Kanner Highway (State Road 76) on Indian Street. It includes construction and operation of a surface water management system to serve the road and bridge project. The total length of the Project is approximately 1.96 miles (1.38 miles of roadway and 0.58 miles of bridge) while the total area is approximately 74.51 acres. After treatment, surface water runoff will discharge to the tidal South Fork of the St. Lucie River. The Project encompasses a bridge crossing the South Fork of the St. Lucie River and the Okeechobee Waterway. Both are classified as Class III waters. The bridge transitions from 4 to 6 lanes east of the Okeechobee Waterway and will require a 55-foot vertical clearance and a 200-foot horizontal clearance between the fender systems at the Okeechobee Waterway. The bridge will cross over a portion of Kiplinger Island owned and preserved by the County. A part of the island was donated to the County in 1993-1994 by The Kiplinger Washington Editors, Inc., and the Kiplinger Foundation, Inc. Audubon of Martin County owns another part of the island. The transfer of title to the County does not include any restriction on the use of the island for conservation purposes only. Documentation submitted at hearing refers to a "two hundred foot wide road right-of-way" easement that the bridge will cross and allows the County to designate where on the island parcel such an easement would be. Therefore, spanning the bridge over a portion of the island owned by the County is clearly permissible. The Project also includes the roadway transition and widening/reconstruction of (a) County Road 714 from the beginning of the Project to Mapp Road from 2-lane to a 4-lane divided roadway; (b) Southwest 36th Street from Mapp Road to the beginning of the bridge from a 2-lane rural roadway to a 4-lane divided roadway with wide roadway swales; and (c) Kanner Highway (along Indian Street) from a 4-lane to a 6-lane divided urban roadway. Drainage improvements on both sides of the St. Lucie River are associated with the roadway construction. DOT proposes to provide both on-site and off-site mitigation for wetland and surface waters impacts pursuant to a mitigation plan approved by the District. The ERP Permitting Criteria In order to obtain an ERP, an applicant must satisfy the conditions for issuance set forth in Florida Administrative Code Rules 40E-4.301 and 40E-4.302. Besides these rules, certain related BOR provisions which implement the rules must also be considered. The conditions for issuance primarily focus on water quality, water quantity, and environmental criteria and form the basis of the District's ERP permitting program. The parties have stipulated that the Project either complies with the following rule provisions or they are not applicable: Rules 40E-4.301(1)(a), (b), (g), (g), (h), and (k), and 40E- 4.302(1)(a)3. and 6. All other provisions remain at issue. Where conflicting evidence on these issues was submitted, the undersigned has resolved all evidentiary conflicts in favor of the Applicants and District. Based on the parties' Stipulation, the following provisions in Rule 40E-4.301(1) are in dispute and require an applicant to provide reasonable assurances that the construction, alteration, operation, maintenance, removal, or abandonment of a surface water management system: will not cause adverse impacts to existing surface water storage and conveyance capabilities; will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters; will not adversely affect the quality of receiving waters such that the water quality standards set forth in chapters 62- 4, 62-302, 62-520, 62-522, 62-550, F.A.C., including any anti-degradation provisions of paragraphs 62-4.242(1)(a) and (b), subsections 62-4.242(2) and (3), and rule 62-302.300, F.A.C., and any special standards for Outstanding Florida Waters and Outstanding National Resource Waters set forth in subsections 62-4.242(2) and (3), F.A.C., will be violated; will not cause adverse secondary impacts to the water resources; will be capable, based on generally accepted engineering and scientific principles, of being performed and of functioning as proposed; will be conducted by an entity with sufficient financial, legal and administrative capability to ensure that the activity will be undertaken in accordance with the terms and conditions of the permit, if issued; These disputed criteria are discussed separately below. Surface Water Storage and Conveyance Rule 40E-4.301(1)(c) requires that an applicant provide reasonable assurances that a proposed activity will not cause adverse impacts to existing surface water storage and conveyance capabilities. Through unrefuted evidence, this requirement was shown to be satisfied. The evidence also establishes that the surface water in and around the Project will actually improve if the Project is constructed as permitted. Further, it will create improved and upgraded surface water management and treatment in areas that now lack features such as swales, retention/detention ponds, curbs and gutters, and improve the overall surface water storage and conveyance capabilities of the Project and surrounding areas. In its current pre-development condition, flooding has occurred in certain areas adjacent to and within the Project area due to poor conveyance, low storage volume, and high tailwater conditions that result from high tides. The Project will remedy historic flooding issues in the Old Palm City area which lies adjacent to a portion of the Project alignment. Surface water runoff will be captured, controlled, and treated by a system of swales, weirs, and retention/detention facilities for pretreatment prior to discharging into the South Fork of the St. Lucie River. Reasonable assurances have been given that existing surface water storage and conveyance capabilities will not be adversely affected. Value of Functions to Fish, Wildlife, and Species Rule 40E-4.301(1)(d) requires that an applicant provide reasonable assurances that a proposed activity will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters. BOR Section 4.2.2 further implements this provision. For the following reasons, the rule and BOR have been satisfied. The evidence shows that the existing functions to fish and wildlife were assessed and analyzed by a number of federal and state fish and wildlife agencies. There were extensive review and site inspections by the District, DOT, United States Fish and Wildlife Service, United States Army Corps of Engineers, and National Marine Fisheries Commission to assess the existence of, and potential impact on, fish and wildlife that may result from the Project. These studies revealed that while portions of the South Fork of the St. Lucie River provide potential habitat for aquatic or wetland-dependent or threatened species of special concern, no nesting or roosting areas within the vicinity of the Project were observed. The evidence further supports a finding that "other surface waters" over and under the Project will not receive unacceptable impacts due to their current condition, the detrimental influences of Lake Okeechobee discharges, and tidal impacts. Many of the wetlands to be impacted by the Project were shown to have been impacted by historic activities, and they provide diminished functions to fish and wildlife. The wetland functions were assessed through the Uniform Mitigation Assessment Methodology (UMAM). The UMAM is a standardized procedure for assessing the functions provided by wetlands and other surface waters, the amount that those functions would be reduced by a proposed project, and the amount of mitigation necessary to offset that loss. Detailed UMAM assessments were prepared by the Applicants and the District. They demonstrate that while certain functional units will be lost, they will be fully offset by the proposed mitigation. No credible evidence to the contrary was presented. Water Quality of Receiving Waters Rule 40E-4.301(1)(e) requires an applicant to provide reasonable assurances that a project will not adversely affect the quality of receiving waters such that State water quality standards will be violated. BOR Section 4.2.4 implements this rule and requires that "reasonable assurances regarding water quality must be provided for both the short term and long term, addressing the proposed construction, . . . [and] operation of the system." The receiving water body is the South Fork of the St. Lucie River, which is designated as an impaired water body. The evidence establishes that the Applicants will avoid and minimize potential short-term impacts to water quality by using silt screens and turbidity barriers, and implementing other best management practices to contain turbidity during construction of the Project. They will also use a temporary trestle rather than barges in the shallow portions of the South Fork to avoid stirring up bottom sediments. Finally, a turbidity monitoring plan will be implemented during construction and dewatering activities for all in-water work. All of these construction techniques will minimize potential impacts during construction. The evidence further establishes that water quality standards will not be violated as a result of the Project. In fact, in some cases water quality will be enhanced due to the installation and maintenance of new or upgraded surface water management features in areas where they do not exist or have fallen into disrepair. Over the long term, the Project is expected to have a beneficial effect on water quality. By improving existing surface water management and adding new surface water treatment features, the Project will provide net improvement to water quality. Wetland Delineation and Impacts The Project includes unavoidable impacts to wetlands and other surface waters. A total of 18.53 acres of wetlands and other surface waters within the Project site will be impacted by the Project, including 3.83 acres of wetlands that will be directly impacted and 14.7 acres of wetlands and other surface waters that will be secondarily impacted. The delineated wetlands are depicted in the Staff Report as wetlands 2a, 19a, 19b, 22, 25-29, 30a, 30b, and 30c, with each having a detailed UMAM assessment of its values and condition. (Impacts to wetland 25 are not included in this Project because they were accounted for in a separate permit proceeding.) Using a conservative assessment and set of assumptions, the District determined that, with the exception of wetlands 19a, 19b, 22, and 27, all wetlands would be impacted by the Project. However, the wetlands that would be impacted suffer from varying historical adverse impacts that have compromised the functions and values they provide to fish, wildlife, and species. This is due to their proximity to urban development, vegetative connectivity, size, historic impacts, altered hydroperiod, and invasive plant species. Likewise, even though the wetlands to be impacted on Kiplinger Island provide certain resting and feeding functions for birds, the value of these functions is comparatively lower than other wetlands due to the presence of invasive species and lack of management. The preponderance of the evidence supports a finding that the Applicants provided reasonable assurances that the Project will not cause adverse impacts to fish, wildlife, or listed species. See Fla. Admin. Code R. 40E-4.301(1)(d). Secondary Impacts Rule 40E-4.301(1)(f) and BOR Sections 4.1.1(f) and 4.2.7. require a demonstration that the proposed activities will not cause adverse secondary impacts to the water resources, both from a wetlands and water quality standpoint. Secondary impacts are those that occur outside the footprint of the project, but which are very closely linked and causally related to the activity to be permitted. De minimis or remotely-related secondary impacts, however, are not considered unacceptable. See § 4.2.7.(a). There will be secondary impacts to 6.83 acres of freshwater wetlands and 7.87 acres of mangroves, or a total of 14.7 acres. To address these secondary impacts, the Applicants have established extensive secondary impact zones and buffers along the Project alignment, which were based in part on District experience with other road projects and another nearby proposed bridge project in an area where a State Preserve is located. While Petitioners' expert contended that a 250-foot buffer on both sides of the roadway's 200-foot right-of-way was insufficient to address secondary impacts to birds (who the expert opines may fly into the bridge or moving vehicles), the greater weight of evidence shows that bird mortality can be avoided and mitigated through various measures incorporated into the Project. Further, the bird mortality studies used by the expert involved significantly different projects and designs, and in some cases involved projects outside the United States with different species concerned. Engineering and Scientific Principles Rule 40E-301(1)(i) requires that an applicant give reasonable assurance that a project "be capable, based on generally accepted engineering and scientific principles, of being performed and of functioning as proposed." Unrefuted evidence establishes that the proposed system will function and be maintained as proposed. Financial, Legal and Administrative Capability Rule 40E-4.301(1)(j) requires that an applicant give reasonable assurance that it has the financial, legal, and administrative capability to ensure that the activity will be undertaken in accordance with the terms of the permit. The evidence supports a finding that Applicants have complied with this requirement. Elimination and Reduction of Impacts Before establishing a mitigation plan, Rule 40E- 4.301(3) requires that an applicant implement practicable design modifications to eliminate and reduce wetland and other surface water impacts. In this case, there are unavoidable, temporary wetland impacts associated with the construction of the Project, as well as unavoidable wetland impacts for direct (project footprint), secondary, and cumulative impacts of the Project. The record shows that the Applicants have undertaken extensive efforts to eliminate and reduce wetland and other surface water impacts of the Project. For example, DOT examined and assessed several innovative construction techniques and bridge designs to eliminate and avoid wetland impacts. To eliminate and reduce temporary impacts occurring during construction, DOT has reduced the effect of scour on the pier foundation and reduced the depth of the footing to minimize the amount of excavation on the mangrove island. Also, during construction, the contractor is prohibited from using the 200- foot right-of-way on the mangrove island for staging or stockpiling of construction materials or equipment. The majority of the bridge width has been reduced to eliminate and avoid impacts. Also, the Project's alignment was adjusted to the north to avoid impacts to a tidal creek. Reasonable assurances have been given that all practicable design and project alternatives to the construction and placement of the Project were assessed with no practicable alternatives. Public Interest Test Besides complying with the requirements of Rule 40E- 4.301, an applicant must also address the seven factors in Rule 40E-4.302(1)(a)1.-7., which comprise the so-called "public interest" test. See also § 373.414(1)(a), Fla. Stat. In interpreting the seven factors, the District balances the potential positive and negative effects of a project to determine if it meets the public interest criteria. Because Petitioners agree that factors 3 and 6 of the rule are not at issue, only the remaining five factors will be considered. For the following reasons, the Project is positive when the criteria are weighed and balanced, and therefore the Project is not contrary to the public interest. Public Health, Safety, and Welfare The Applicants have provided reasonable assurance that the Project will not affect public health, safety, and welfare. Specifically, it will benefit the health, safety, and welfare of the citizens by improving traffic conditions and congestion, emergency and hurricane evacuation, and access to medical facilities. In terms of safety, navigation markers are included as part of the Project for safe boating by the public. See Fla. Admin. Code R. 40E-4.302(1)(a)1. Conservation of Fish and Wildlife The activity will not adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats. The mitigation projects will offset any impacts to fish and wildlife, improve the abundance and diversity of fish and wildlife on Kiplinger Island, create mangrove habitat, and add to the marine productivity in the area by enhancing water quality. See Fla. Admin. Code R. 40E-302(1)(a)2. Fishing or Recreational Values The Project has features that allow for pedestrian and bicycle utilization and observation areas which should enhance recreational values. The Old Palm Bridge, approximately one mile north of the Project, has had no adverse impact on the fishing recreation along the South Fork of the St. Lucie River. Navigation will not be affected due to the height and design of the new bridge. Finally, the bridge is expected to be a destination for boating, kayaking, fishing, and bird watching. See Fla. Admin. Code R. 40E-4.302(1)(a)4. Whether the Activity is of a Permanent Nature The parties have stipulated that the Project is permanent in nature. No future activities or future phases of the project are contemplated. Temporary and permanent impacts are all being fully mitigated. See Fla. Admin. Code R. 40E- 4.302(1)(a)5. Values of Functions Being Performed in Affected Areas Due to historic impacts to the areas affected by the Project, the current condition is degraded and the relative value of functions is minimal. Although Kiplinger Island will have temporary impacts, that island is subject to exotic species and has no recreational use or access by boaters or members of the public. The Applicants propose mitigation which will improve and enhance these wetland functions and values in the areas. See Fla. Admin. Code R. 40E-4.302(1)(a)7. Summary The evidence supports a finding that the Project is positive as to whether it will affect the public health, safety, welfare, or property of others; that the Project is neutral with respect to navigation, erosion and shoaling, and water flow, as well as to historical and archaeological concerns; and that the Project is positive as to conservation of fish, wildlife, recreational values, marine productivity, permanency, and current values and functions. When weighed and balanced, the Project is not contrary to the public interest. Cumulative Impacts Rule 40E-4.302(1)(b) requires that an applicant give reasonable assurance that a project will not cause unacceptable cumulative impacts upon wetlands and other surface waters as set forth in BOR Sections 4.28 through 4.2.8.2. Cumulative impacts are the summation of unmitigated wetland impacts within a drainage basin. An analysis is geographically based upon the drainage basins described in BOR Figure 4.4.1. Petitioners' contention that Figure 4.4.1 is inaccurate or not representative of the basin in which the Project is located has been rejected. In this case, the North St. Lucie Basin was used. To assess and quantify any potential unacceptable cumulative impacts in the basin, and supplement the analyses performed by the Applicants, the District prepared a Basin Map that depicted all the existing and permitted wetland impacts as well as those wetlands under some form of public ownership and/or subject to conservation restrictions or easements. The District's analysis found that the wetlands to be mitigated were of poor quality and provided minimal wildlife and water quality functions. Cumulative impacts from the Project to wetlands within the basin resulted in approximately a four percent loss basin-wide. This is an acceptable adverse cumulative impact. Therefore, the Project will not result in unacceptable cumulative impacts. Mitigation Adverse impacts to wetlands caused by a proposed activity must be offset by mitigation measures. See § 4.3. These may include on-site mitigation, off-site mitigation, off- site regional mitigation, or the purchase of mitigation credits from mitigation banks. The proposed mitigation must offset direct, secondary, and cumulative impacts to the values and functions of the wetlands impacted by the proposed activity. The ability to provide on-site mitigation for a DOT linear transportation project such as a bridge is limited and in this case consists of the creation of mangrove and other wetlands between the realigned St. Lucie Shores Boulevard and the west shore of the St. Lucie River, north and south of the proposed bridge crossing. BOR Section 4.3.1.2 specifically recognizes this limitation and allows off-site mitigation for linear projects that cannot effectively implement on-site mitigation requirements due to right-of-way constraints. Off-site mitigation will offset the majority of the wetland impacts. Because no single on-site or off-site location within the basin was available to provide mitigation necessary to offset all of the Project's impacts, DOT proposed off-site mitigation at two established and functioning mitigation areas known as Dupuis State Reserve (Dupuis), which is managed by the County and for which DOT has available mitigation credits, and the County's Estuarine Mitigation Site, a/k/a Florida Oceanographic Society (FOS) located on Hutchinson Island. Dupuis is outside the North St. Lucie Basin and was selected to offset direct and secondary impacts to freshwater wetlands. That site meets the ERP criteria in using it for this project. The FOS is within the North St. Lucie Basin and was selected to offset direct and secondary impacts to estuarine wetlands. Like Dupuis, this site also meets the ERP criteria for the project. The preponderance of the evidence establishes that the on-site and off-site mitigation projects fully offset any and all project impacts, and in most instances before the impacts will actually occur. Sovereign Submerged Lands and Heightened Public Concern Chapter 18-21 applies to requests for authorization to use sovereign submerged lands. The management policies, standards, and criteria used to determine whether to approve or deny a request are found in Rule 18-21.004. For purposes of granting a public easement to the Applicants, the District determined that the Project is not contrary to the public interest and that all requirements of the rule were satisfied. This determination was not disputed. The only issue raised by Petitioners concerning the use of submerged lands is whether the application should have been treated as one of "heightened public concern." See Fla. Admin. Code R. 18-21.0051(5). If a project falls within the purview of that rule, the Board of Trustees of the Internal Improvement Trust Fund (Board), rather than the District, must review and approve the application to use submerged lands. Review by the Board is appropriate whenever a proposed activity is reasonably expected to result in a heightened public concern because of its potential effect on the environment, natural resources, or controversial nature or location. Id. In accordance with established protocol, the ERP application was sent by the District to DEP's review panel in Tallahassee (acting as the Board's staff) to determine whether the Project required review by the Board. The panel concluded that the Project did not rise to the level of heightened public concern. Evidence by Petitioners that "many people" attended meetings and workshops concerning the Project over the last 20 years or so is insufficient to trigger the rule. Significantly, except for general project objections lodged by Petitioners and Audubon of Martin County, which did not include an objection to an easement, no adjacent property owner or other member of the public voiced objections to the construction of a new bridge. Revised Staff Report On October 20, 2010, the District issued a Revised Staff Report that merely corrected administrative errors or information that had been previously submitted to the District. Contrary to Petitioners' assertion, it did not constitute a material change to the earlier agency action either individually or cumulatively. Therefore, it was properly considered in this proceeding. Letter Modifications The Letter Modifications were used as a mechanism to capture minor alterations made to previously issued permits for Kanner Highway and Indian Street. Neither Letter Modification is significant in terms of water quality, water quantity, or environmental impacts. Both were issued in accordance with District rules and should be approved.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the South Florida Water Management District enter a final order granting Application Nos. 091021-8, 100316-7, and 100316-6.

The Issue The issue is whether the applicant for an Environmental Resource Permit ("ERP"), the City of Deltona ("City" or "Applicant"), has provided reasonable assurance that the system proposed complies with the water quantity, environmental, and water quality criteria of the St. Johns River Water Management District's ("District") ERP regulations set forth in Florida Administrative Code Chapter 40C-4, and the Applicant's Handbook: Management and Storage of Surface Waters (2005).
Findings Of Fact The District is a special taxing district created by Chapter 373, Florida Statutes, charged with the duty to prevent harm to the water resources of the District, and to administer and enforce Chapter 373, Florida Statutes, and the rules promulgated thereunder. The City of Deltona is a municipal government established under the provisions of Chapter 165, Florida Statutes. The Lake Theresa Basin is comprised primarily of a system of interconnected lakes extending from Lake Macy in the City of Lake Helen to the Butler Chain of Lakes (Lake Butler and Lake Doyle). The Lake Theresa Basin is land-locked and does not have a natural outfall to Lake Monroe and the St. Johns River. In 2003, after an extended period of above-normal rainfall in the Deltona area, the lakes within the land-locked Lake Theresa Basin staged to extremely high elevations that resulted in standing water in residential yards, and rendered some septic systems inoperable. Lake levels within the Lake Theresa Basin continued to rise and were in danger of rising above the finished floor elevations of some residences within the basin. On March 25, 2003, the District issued an Emergency Order (F.O.R. No. 2003-38) authorizing the construction and short-term operation of the Lake Doyle and Lake Bethel Emergency Overflow Interconnection. Since wetland and surface water impacts would occur, the Emergency Order required the City of Deltona to obtain an ERP for the system. The project area is 4.1 acres, and the system consists of a variable water structure on the west shore of Lake Doyle connected to a series of pipes, swales, water control structures, and wetland systems which outfall to a finger canal of Lake Bethel, with ultimate discharge to Lake Monroe and the St. Johns River. The first segment of the system extends downstream from the weir structure on the west shore of Lake Doyle via a pipe entrenched in the upland berm of the Sheryl Drive right-of-way. The pipe passes under Doyle Road and through xeric pine-oak uplands to the northeast shore of a large (approximately 15 acres) deepwater marsh. Water flows south through the deepwater marsh where it outfalls through four pipes at Ledford Drive. Two of the four pipes are overflow structures, controlled by canal gates. The pipes at Ledford Drive discharge into a ditch and into a large (greater than 20 acres) shallow bay swamp. The south end of the bay swamp is defined (and somewhat impounded) by a 19th Century railroad grade. Water flows through the bay swamp where it outfalls through five pipes at the railroad grade. Three of the five pipes are overflow structures, controlled by channel boards. The pipes at the railroad grade discharge to a 1500-foot long finger canal that was dug some time during the period 1940-1972 from the north central shore of Lake Bethel. The overflow interconnection system has three locations whereby the system can be shut down: 1) Lake Doyle--a control weir, controlled by three sluice gates; 2) Ledford Drive--two thirty-inch reinforced concrete pipes, controlled by canal gates; and 3) railroad grade--three thirty-inch reinforced concrete pipes, controlled by channel boards (collectively referred to as "Overflow Structures"). The Overflow Structures are designed to carry the discharge of water from Lake Doyle to Lake Bethel. With the Overflow Structures closed the system returns to pre-construction characteristics, meaning there will be no increase or decrease in the quantity or quality of water throughout the path of the system as a result of the project. An unequivocal condition of the permit is that the system would operate with all of the Overflow Structures closed. As an added assurance, the City proposes to place a brick and mortar plug in the Lake Doyle weir structure outfall pipe to prevent any discharge from the weir. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the water level in Lake Doyle rises above an elevation of 24.5 feet. The District shall require a separate permit application to be submitted for such future plans. Petitioner, Barbara Ash, has lived on Lake Theresa for 19 years. Ms. Ash lives upstream from the area of the weir that will be plugged in accordance with the ERP. She does not trust either the City of Deltona to comply with or the District to enforce the conditions of the ERP applied for by the City. Petitioner, Barbara Ash, also served as the qualified representative for Petitioners, Francell Frei, Bernard J. and Virginia Patterson, and Ted and Carol Sullivan. Ms. Ash represented that Ms. Frei has lived on Lake Theresa for 12 years, and both the Pattersons and the Sullivans live on Lake Louise, which is within the area of concern in this proceeding. Petitioner, Diana Bauer, has lived on Lake Theresa since February 2004. She fears that the lake will become too dry if the system is allowed to flow. She also believes the wildlife will be adversely affected if the water levels are too low since many species need a swampy or wet environment to thrive. She fears her property value will decrease as a result of the approval of the ERP. She also does not trust either the City to comply with or the District to enforce the conditions of the ERP. Petitioner, Howard Ehmer, lives two to three hundred yards down Lake Theresa from Ms. Bauer. He is concerned about the lake bed being too dry and attracting people on all terrain vehicles who enjoy driving around the lake bottom. He is concerned about his property value decreasing if the lake bed is dry. Further, when the lake level is too low, people cannot enjoy water skiing, boating, and fishing on Lake Theresa. Petitioner, Phillip Lott, a Florida native, has also owned and lived on property abutting Lake Theresa since 1995. Mr. Lott has a Ph.D. in plant ecology, and M.P.A. in coastal zone studies, an M.B.A. in international business, and a B.S. in environmental resource management and planning. Mr. Lott has been well acquainted with the water levels on Lake Theresa for many years. Based upon his personal observations of the lake systems in the Deltona area over the years, Mr. Lott has seen levels fluctuate greatly based upon periods of heavy and light rainfall. Mr. Lott is concerned that the District will permit the City to open the weir to let water flow through the system and cause flooding in some areas and low water levels in other areas. He fears that the District will allow the water to flow and upset the environmental balance, but he admits that this ERP application is for a closed system that will not allow the water to flow as he fears. Mr. Lott similarly does not trust the City to comply with and the District to enforce the conditions of the ERP. Petitioners, James E. and Alicia M. Peake, who were represented by Steven L. Spratt at hearing as their qualified representative, live on Lake Louise, which is interconnected with the Lake Theresa basin. The Peakes are concerned that if the level of Lake Louise drops below 21 feet, nine inches, they will not be able to use the boat launch ramps on the lake. Petitioner, Steven L. Spratt, also lives on Lake Louise, and is concerned about the water levels becoming so low that he cannot use the boat launch on the lake. He has lived on the lake since 2000, and remembers when the water level was extremely low. He fears that approval of the ERP in this case will result in low levels of water once again. Petitioner, Gloria Benoit, has live on Lake Theresa for two years. She also enjoys watching recreational activities on the lake, and feels that approval of the ERP will devalue her lakefront property. Ms. Benoit appeared at the first day of the hearing, but offered no testimony on her behalf. J. Christy Wilson, Esquire, appeared prior to the final hearing as counsel of record for Petitioners, Steven E. Larimer, Kathleen Larimer, and Helen Rose Farrow. Neither Ms. Wilson nor any of the three Petitioners she represented appeared at any time during the hearing, filed any pleadings seeking to excuse themselves from appearing at the final hearing, or offered any evidence, testimony, pre- or post- hearing submittals. Petitioner, Gary Jensen, did not appear at hearing, did not file any pleadings or papers seeking to be excused from appearing at the final hearing, and did not offer any evidence, testimony, pre- or post-hearing submittals. Both the City and the District recognize that areas downstream from the project site, such as Stone Island and Sanford, have experienced flooding in the past in time of high amounts of rainfall. The system proposed by the City for this ERP will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel. So long as the overflow structures are closed, the system will mimic pre-construction flow patterns, with no increase in volume flowing downstream. The District has considered the environment in its proposed approval of the ERP. The area abutting the project is little urbanized and provides good aquatic and emergent marsh habitat. With the exception of the western shore area of the deepwater marsh ("west marsh area"), the bay swamp and remaining deepwater marsh area have good ecological value. In the 1940's, the west marsh area was incorporated into the drainage system of a poultry farm that occupied the site. This area apparently suffered increased nutrient influxes and sedimentation that contributed to a proliferation of floating mats of aquatic plants and organic debris. These tussocks reduced the deepwater marsh's open water and diminished the historical marsh habitat. Water under the tussocks is typically anoxic owing to total shading by tussocks and reduced water circulation. Thick, soft, anaerobic muck has accumulated under the matted vegetation. Exotic shrubs (primrose willow Ludwigia peruvania) and other plants (cattails Typha spp.) dominate the tussocks. The construction of the project, from the 2003 Emergency Order, resulted in adverse impacts to 1.3 acres of wetlands having moderately high- to high ecological value and 0.2 acres of other surface waters. The 0.2 acre impact to other surface waters was to the lake bottom and the shoreline of Lake Doyle where the weir structure was installed. The 0.3 acres of wetland impacts occurred at the upper end of the deepwater marsh where the pipe was installed. The largest wetland impact (1.0 acre) was to the bay swamp. The bay swamp is a shallow body dominated by low hummocks and pools connected inefficiently by shallow braided channels and one acre is filled with a 1-2 foot layer of sediment following swamp channelization. Disturbance plants (e.g., primrose willow, Ludwigia peruvania, and elderberry Sambucus Canadensis) now colonize the sediment plume. Pursuant to the District's elimination and reduction criteria, the applicant must implement practicable design modifications, which would reduce or eliminate adverse impacts to wetlands and other surface waters. A proposed modification, which is not technically capable of being done, is not economically viable, or which adversely affects public safety through endangerment of lives or property is not considered "practicable." The City reduced and/or eliminated the impacts to the lake bottom and shoreline of Lake Doyle and deepwater marsh, to the extent practicable. The impacts were the minimum necessary to install the weir structure and pipe for the system; the weir structure and pipe were carefully installed on the edges of the wetland and surface water systems, resulting in a minimum amount of grading and disturbance. To compensate for the loss of 1.3 acres of wetlands and 0.2 acres of other surface waters, the City proposes to preserve a total of 27.5 acres of wetlands, bay swamp, marsh, and contiguous uplands. Included in this 27.5 acres are 6.4 acres of the west marsh, which are to be restored. The parties stipulated that the mitigation plan would adequately compensate for losses of ecological function (e.g. wildlife habitat and biodiversity, etc.) resulting from the project. Water quality is a concern for the District. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies for nitrogen, phosphorous, and dissolved oxygen. Water quality data for Lake Monroe indicate the lake has experienced high levels of nitrogen and phosphorous and low levels of dissolved oxygen. Prior to construction of the project, there was no natural outfall from the Lake Theresa Basin to Lake Monroe and therefore no contribution from this basin to nitrogen and phosphorous loadings to Lake Monroe. Lake Colby, Three Island Lakes (a/k/a Lake Sixma), and the Savannah are surface waters within the Lake Theresa Basin for which minimum levels have been adopted pursuant to Florida Administrative Code Chapter 40C-8. The system will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel, resulting in no outfall from the Theresa Basin to Lake Monroe. Minimum flows established for surface waters within the Lake Theresa Basin will not be adversely impacted. Under the first part of the secondary impact test, the City must provide reasonable assurance that the secondary impacts from construction, alteration, and intended or reasonable expected use of the project will not adversely affect the functions of adjacent wetlands or surface waters. The system is designed as a low intensity project. As proposed, little activity and maintenance are expected in the project site area. The reasonably expected use of the system will not cause adverse impacts to the functions of the wetlands and other surface waters. None of the wetland areas adjacent to uplands are used by listed species for nesting or denning. In its pre-construction state, the project area did not cause or contribute to state water quality violations. Under the second part of the secondary impact test, the City must provide reasonable assurance that the construction, alteration, and intended or reasonably expected uses of the system will not adversely affect the ecological value of the uplands to aquatic or wetland dependent species for enabling existing nesting or denning by these species. There are no listed threatened or endangered species within the project site area. Under the third part of the secondary impact test, and as part of the public interest test, the District must consider any other relevant activities that are closely linked and causally related to any proposed dredging or filling which will cause impacts to significant historical and archaeological resources. When making this determination, the District is required, by rule, to consult with the Division of Historical Resources. The Division of Historical Resources indicated that no historical or archaeological resources are likely present on the site. No impacts to significant historical and archaeological resources are expected. Under the fourth part of the secondary impact test, the City must demonstrate that certain additional activities and future phases of a project will not result in adverse impacts to the functions of wetlands or water quality violations. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the level in Lake Doyle rises above an elevation of 24.5 feet. Based upon the plans and calculations submitted, the proposed future phase, without additional measures, could result in minor increases in the loadings of nitrogen and phosphorous to Lake Monroe. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies due to water quality data indicating the lake has experienced high levels of nitrogen and phosphorous, and low levels of dissolved oxygen. Under this potential future phase, there would be an outfall from the Lake Theresa Basin to Lake Monroe. To address the impact on water quality of this potential future phase, the City has submitted a loading reduction plan for nitrogen, phosphorous, and dissolved oxygen. The plan includes compensating treatment to fully offset the potential increased nutrient loadings to Lake Monroe. Specifically, the loading reduction plan includes: Construction and operation of compensating treatment systems to fully offset anticipated increased nutrient loadings to Lake Monroe. Weekly water quality monitoring of the discharge from Lake Doyle for total phosphorous and total nitrogen. A requirement that the overflow structure be closed if the total phosphorous level reaches 0.18 mg/l or higher or the total nitrogen level reaches 1.2 mg/l or higher in any given week and will remain closed until levels fall below those limits. The implementation of these water quality mitigation measures will result in a net improvement of the water quality in Lake Monroe for nitrogen, phosphorous, or dissolved oxygen. The future phase was conceptually evaluated by the District for impacts to wetland functions. The future phase as proposed could result in adverse impacts to wetland functions. Operation of the system with the overflow structures open could impact the bay swamp and deepwater marsh. The City has demonstrated that any adverse impacts could be offset through mitigation. Based upon the information provided by the City and general engineering principles, the system is capable of functioning as proposed. The City of Deltona will be responsible for the operation, maintenance, and repair of the surface waster management system. A local government is an acceptable operation and maintenance entity under District rules. The public interest test has seven criteria. The public interest test requires the District to evaluate only those parts of the project actually located in, on, or over surface waters or wetlands, to determine whether a factor is positive, neutral, or negative, and then to balance these factors against each other. The seven factors are as follows: the public health, safety, or welfare of others; conservation of fish and wildlife and their habitats; fishing, recreational value, and marine productivity; temporary or permanent nature; 5) navigation, water flow, erosion, and shoaling; 6) the current condition and relative value of functions; and 7) historical and archaeological resources. There are no identified environmental hazards or improvements to public health and safety. The District does not consider impacts to property values. To offset any adverse impacts to fish and wildlife and their habitats, the City has proposed mitigation. The areas of the project in, on, or over wetlands do not provide recreational opportunities. Construction and operation of the project located in, on, or over wetlands will be permanent in nature. Construction and operation of the project located in, on, or over wetlands will not cause shoaling, and does not provide navigational opportunities. The mitigation will offset the relative value of functions performed by areas affected by the proposed project. No historical or archaeological resources are likely on the site of the project. The mitigation of the project is located within the same drainage basin as the project and offsets the adverse impacts. The project is not expected to cause unacceptable cumulative impacts.

Findings Of Fact The property has been annexed into the Acme Improvement District (Intervenor) by Special Act of the Florida Legislature. Petitioner purchased 487.7 acres of this tract from private owners in 1954. Subsequently, Petitioner purchased 653.59 acres from the Trustees of the Internal Improvement Fund of the State of Florida on or about March 4, 1960. The balance of the land constituting the property is a 224 acre hiatus tract owned by Marshall Brown with whom Petitioner has an agricultural use agreement. A parcel of Petitioner's land within the property includes a commercial lease to Malrite Corporation for siting a television antenna, consisting of 111 acres in the southeast corner of the property. This area is within the permit application. The tract is otherwise undeveloped and is currently submerged or semi- submerged during much of the year. Petitioner's development plan envisions drainage of this tract and use of the property for cultivation. The property is bounded on the north by Acme Improvement District, on the east by a subdivision called Homeland, on the west by Water Conservation Area #1, also known as the Loxahatchee Refuge, and on the south by undeveloped lands. The boundaries of the Loxahatchee Refuge actually encroach by approximately 300 feet into the property. The property development plan, which is the basis of this application, was prepared by the engineering firm Gee and Jensen. This plan calls for the creation of a 240 acre reservoir of a proposed 3 foot maximum depth. This reservoir would hold the internal stormwater runoff for subsequent agricultural irrigation. Perimeter dikes are to be constructed to prevent surface water runoff from outside areas entering the project and perimeter ditches are to be developed for the deliverance of stormwater runoff from the internal agricultural system to proposed pump stations located at the southwest corner of the development area. On the northwest corner of the proposed reservoir, the existing Acme Improvement District pump station No. 2 would be increased in capacity by 27,000 gallons per minute. Under Acme's charter and its statutory annexation of the property, the proposed reservoir and water management works would become a unit of development controlled by Acme. Under Petitioner's agreement with the hiatus tract owner, Acme would be the exclusive manager and operator of the proposed system, and the property would become an integral part of Acme's water management system. The Acme Water Improvement District is not solely an agricultural support enterprise but serves the various uses which may evolve within its boundaries. The area is currently zoned for limited residential development as well as agricultural. The television antenna facility located on the property is an example of a non-agricultural use. Petitioner's surface water management system is proposed to discharge into the Acme system, which in turn discharges offsite. Discharge into the Acme system is of a limited nature, but the system is designed to discharge for successive days under wet conditions. The design discharge is not limited to an extreme rainfall event but would probably occur during the traditional hydrologic cycle of south Florida. Under conditions which reflect actual rainfall over the past 20 years, the proposed surface water management system would have discharged 19 out of 20 years into the Water Conservation Area (Loxahatchee Refuge). In some years this discharge would have continued for approximately three months. The unrebutted testimony of expert witnesses called by Respondent established that the entire 1,393 acre tract referred to herein as "the property" is a freshwater wetland habitat. The western half is emergent marsh land, while the eastern half is forested with woody species. The wetlands on the property form a valuable wildlife habitat. Environmentally, they are in excellent condition. This area has not been adversely affected by drainage, fire or exotic species. These marshes also have good habitat diversity. The populations of aquatic invertebrates and forage fishes that are produced in these Everglades marshes are utilized by the many species of wading birds that feed in these wetlands. The proposed project will adversely affect wildlife species, including a variety of wading birds which will likely be unable to relocate. While this is undesirable from an environmental standpoint, conversion of this land would provide benefits from an agricultural standpoint, and would create additional water recreational facilities.
Recommendation From the foregoing, it is RECOMMENDED: That Respondent enter a final order denying the application. DONE and ORDERED this 30th day of November, 1983, in Tallahassee, Florida. R. T.
