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 The following findings of fact are based on the evidence presented and relate both to Fairfield's MSSW and CUP applications: Fort George Island is an approximately 900 acre island located northeast of the City of Jacksonville in Duval County, Florida. It is bounded to the north and east by the Fort George River, to the west by an extensive salt marsh, and to the south by Batten Island and the St. Johns River. The island is separated from the Atlantic Ocean by Little Talbot Island. There are presently approximately 16 homes on Fort George Island, an existing 18-hole golf course with clubhouse, the Kingsley Plantation State Park in the north and the Rollins site surface waters on the northern two-thirds of the island are Class II waters, while the waters to the south are Class III. The following factors concerning Fort George Island are of ecological significance: Existence of a large area of coastal hammock; Value of the coastal hammock for scientific research and as a food source for migrating song birds; Fact that the Island is located in an aquatic preserve; Salt marshes on the western side of the Island which are a food source for wading birds; State lands on the Island which are utilized as wildlife and plant preserve, as well as for historical purposes; Estuaries on the western side of the Island which function as primary nursery areas for commercial and sport fishery species, as well as for shrimp, oysters and crabs; Existence of commercial oyster leases on the western side of the Island; and Public use of the Island's shoreline for oystering and clamming. Fairfield owns approximately 757.5 acres on Fort George Island which it proposes to develop into a "planned unit development" of 1,343 dwelling units, a 27 hole golf course, and approximately 80,000 square feet of commercial development. The approximate density of the development will be 1.8 units per acre. Approximately 80% of Fairfield's property is currently forested, and after development approximately 35% will remain undisturbed habitat. The City of Jacksonville approved the "planned unit development" on January 10, 1983. Because the Department of Community Affairs had determined on August 11, 1982, that this development was a "development of regional impact," Fairfield submitted an Application for Development Approval to the Department, the Northeast Florida Regional Planning Council, and the City of Jacksonville, which subsequently approved the proposed development in an Amended Development Order. On January 25, 1984, the Florida Land and Water Adjudicatory Commission approved the Amended Development Order (ADO). In addition to approving the development of maximum of 1,343 units, 80,000 square feet of commercial area, two 18 hole golf courses (one already in existence), and a marina with not more than 50 slips, the ADO required Fairfield to conduct a 12 month study and prepare a Master Resource Management Plan prior to development. Specifically, Fairfield was required to demonstrate that there is a sufficient supply of potable ground water to serve the entire development without adverse effects on the Floridan Aquifer and other existing legal users; establish the ambient conditions of the water surrounding Fort George Island and the ambient climatic conditions of the Island and Rollins Sanctuary through a 12 month monitoring program; identify all endangered, threatened, unique, rare, notable and "species of special concern" and determine their habitat requirements; address surface water quality and quantity, terrestrial and wetlands biology, and ground water quality and quantity for the entire project; and submit a revised Master Land Use Plan, consistent with the Master Resource Management Plan, to the City of Jacksonville's Planning Commission for its approval. Further, the ADO required Fairfield to demonstrate that it could retain the 100 year, 24-hour storm (calculated to be 11.04 inches of rain in 24 hours), and prevent degradation of the established ambient conditions of the waters surrounding Fort George. Finally, the ADO required Fairfield to submit its Master Resource Management Plan to the City, Regional Planning Council, Department of Community Affairs, Department of Environmental Regulation, Department of Natural Resources, Game and Fresh Water Fish Commission, and the District, for their, review, comment, and in some cases approval. After review and comment by these agencies, the City of Jacksonville Planning Commission approved the Master Resource Management Plan on January 29, 1986, from which no appeal was taken. Case Number 85-3537 (MSSW) The following findings of fact are based upon the stipulation of the parties and relate to Fairfield's MSSW application: The District, a special taxing district and agency, created by Chapter 373, is charged with the statutory responsibility of the administration and enforcement of permitting programs pursuant to Sections 373.413 and 373.416, Florida Statutes, and Chapter 40C-4, Florida Administrative Code. The District is the agency involved in this proceeding. The District has assigned Fairfield's conceptual MSSW permit application the permit number 4-031-002AC. Fairfield is a Delaware corporation authorized to do business in Florida. Its address is 3520 Piedmont Road, N.E., Atlanta, Georgia 30305. The proposed MSSW will serve Fairfield's development on Fort George Island, located in Duval County at Section 34, Township 15, Range 29 East. Petitioner Friends of Fort George, Inc., is a not-for- profit Florida Corporation, whose principal office for the transaction of business is located at 11251 Fort George Road, East, Jacksonville, Florida 32226. Petitioner in Intervention Southeastern Fisheries Association is a Florida not-for profit corporation whose address is 312 East Georgia Street, Tallahassee, Florida 32301. Petitioner in Intervention Logan Diving, Inc., is a Florida corporation whose address is 5731 St. Augustine Road, Jacksonville, Florida 32207. Petitioners in Intervention Florida Audubon Society and Duval Audubon Society are not-for-profit Florida corporations whose principal offices for the transaction of business are located at 1101 Audubon Way, Maitland, Florida 32751 and 2°65 Forest Circle, Jacksonville, Florida 32217. Individual Petitioners William E. Arnold, Jr., William M. Bliss, Doris B. Chappelle, Leo E. Chappelle, Mr. & Mrs. Rhodes Gay, Dr. & Mrs. William J. Knauer, Jr., Camillus S. Lengle, Jr., and Mr. & Mrs. J. W. Lucas are natural persons and citizens of the State of Florida who are owners of real property on Fort George Island. On August 27, 1985, the District gave Notice of its intent to deny MSSW application No. 4-031-002AC. On September 23, 1985, the District determined to recommend issuance of MSSW Application No. 4-031-002AC, as then modified, with conditions. Fairfield had originally contemplated in both its original Master Resource Management Plan (MRMP) and the referenced MSSW application that its proposed development for Fort George Island would have a 36-hole golf course facility. Fairfield subsequently reduced its proposed golf course facility from 36 holes to 27 holes. The City of Jacksonville's Planning Commission approved the MRMP with conditions, including the condition that the golf course be reduced, on January 29, 1986. Because of the reduction in size of Fairfield's proposed golf course facility from 36 to 27 holes Fairfield's total requirements for water for irrigation were reduced. By pleading dated April 7, 1986, Fairfield moved to amend its conceptual MSSW approval application. On April 10, 1986, the motion was granted pursuant to Stipulation of all the parties. The motion was granted by written Order of the Hearing Officer on April 17, 1986. The Petitioners' original Petition for Formal Administrative Proceedings was timely filed within fourteen (14) days of receipt of the District's proposed agency action of September 23, 1985. A number of the members of Friends of Fort George, Inc. own real property on Fort George Island, reside on the Island, and engage in recreational activities on the Island and its adjacent waters and environs. The subject matter of the proposed agency action challenged by Petitioners and Intervenors concerns the natural resources on Fort George Island. Protection of this resource falls within-the general purpose and objectives of Friends of Fort George, Inc., namely, the preservation, conservation, and restoration of Fort George Island and surrounding environs. The relief requested in this proceeding by Petitioners and Intervenors is denial of the conceptual management and storage of surface waters permit. The water storage ponds proposed in the project will intersect with the surficial aquifer on Fort George Island. Petitioners, Friends of Fort George, Inc. and Intervenors, Florida Audubon Society and Duval Audubon Society have standing pursuant to Section 403.412(5), Florida Statutes, to bring this action. During the hearing, the parties stipulated that Logan Diving, Inc., has standing in this proceeding since it is the holder of oyster and clam harvesting leases from the Department of Natural Resources for beds located in Class II waters adjacent to Fort George Island and it derives substantial income from harvesting of these beds. Closure or reclassification of these waters to limit or preclude shellfish harvesting would impair the value of Logan Diving's shellfish leases, or render them worthless. The following findings of fact relating to Fairfield's MSSW application are based upon the evidence presented, including the demeanor and credibility of witnesses who testified: Southeastern Fisheries Association, Inc., established at the hearing that it is a not-for-profit incorporated association of seafood producers, packers, canners, processors, wholesalers, retailers and others substantially involved in the seafood and fishing industries. Based upon the testimony of Robert P. Jones, 200 to 250 of the Association's 350 members shrimp in waters in the vicinity of Fort George Island, 26 of its members are residents of Duval or Massau Counties and 6 are residents of Fort George Island. Thus, a significant number of the Association's members harvest and transport seafood from the waters in the area of Fort George Island, and others also pack and process seafood from these waters. They would be substantially affected if the quality of these waters was degraded, or if the waters were closed to shellfish harvesting as a result of destruction to the nursery areas or reduction in quality or quantity of fish or shellfish which are harvested in these waters, or which utilize these waters as nursery areas. The objectives and purposes of the Association include promoting the general welfare of the fisheries industry and enhancing its economic progress. In contrast, the Florida Wildlife Federation was allowed to participate in this hearing but failed to offer any evidence in support of its verified Petition at the hearing. Fairfield's MSSW application is for conceptual approval, pursuant to District rule, and if conceptual approval is obtained Fairfield will then have to re-apply for construction, operation and maintenance MSSW permits. Although this is an application for conceptual approval, the documentation and information submitted by Fairfield to the District in support of its application is more thorough and complete than almost any other application for conceptual approval received by the District, and is actually superior to the documentation and information received from most applicants for construction permits. According to District staff, more sampling and testing results are presented in this conceptual application than they ever get. After initial review of its MSSW application by District staff following submission on January 5, 1984, Fairfield received a request for additional information. In responding to this request, Fairfield developed a plan of study which was approved by District staff and which focused on the water supply potential of the surficial aquifer, and the ability of a stormwater management and control system to retain stormwater on-site in compliance with the ADO and the District's permitting rules. Fairfield's study was comprehensive, and was completed in a very competent, professional manner. It included the collection of data through soil borings, installation of monitoring wells, conducting permeability and percolation tests, collecting rainfall data' and sampling of water quality. A water budget model was developed, and approved by the District, to compare existing conditions to proposed developed conditions and to specifically determine the water supply potential of the surficial aquifer, assess the availability of water for irrigation after development, assess changes in recharge to the surficial aquifer after development, and generally to determine how the development would impact the existing hyrologic cycle on the Island. Considering all of the evidence presented, it is specifically found that Fairfield utilized correct and appropriate input parameters in its water budget model to determine that currently 17.5 inches per year of freshwater is flowing from the Island to the surrounding estuary under average annual rainfall conditions, and after development approximately 16 inches per year of freshwater will flow from the Island to the estuary--less than a 10% change in ground- water flowing to the estuary. Therefore, the subject development will not adversely impact the overall water balance on Fort George Island. Utilizing the water budget model, under developed conditions it is shown that in a one-in-ten dry year there will be slightly more fresh water flow from the Island, and in a one-in-ten wet year there will be slightly less freshwater flow to the estuary than currently exists. This further demonstrates that overall water balance will be maintained. Total recharge will be greater post-development in average, wet and dry years. Fairfield's stormwater management system consists of a series of golf course fairway retention areas, and also includes four ponds in the north of the island which are interconnected, and one in the south, into which storm water will flow. The retention ponds comprise an area of approximately 32 acres. The fairway retention areas maximize percolation or infiltration, and water that remains to enter these ponds will be used for golf course irrigation through pumping. Generally, 95% of golf course need will be met by such pumping from the ponds, with the remaining need being met by withdrawals from the Floridan Aquifer. Under dry conditions, the need to withdraw from the Floridan Aquifer will be greater and could approach 49% of golf course irrigation requirements. The fairway retention areas and the five storage ponds comprise an on-line treatment system which will retain the first one-half inch of runoff, as well as additional runoff. Fairfield's on-line system is equivalent to an off-line system required by Rule Chapter 40C-42, Florida Administrative Code, for discharges to Outstanding Florida Waters (OFW) such as those that surround Fort George Island. Thus, the "first flush" containing a higher level of pollutants will be received by the retention areas and ponds in this on-line system and will primarily be removed through percolation in the retention areas. Pollutants should not be discharged into the estuaries, even in emergencies or when conditions exceed design capacity. Pond retention time will be approximately two months and surficial runoff will account for 5%-10% of the water in the ponds, with the rest coming from ground-water in-flow. Fairfield's storm water management system is operational and maintainable. It will be able to retain the 100 year, 24 hour storm event and otherwise meet the District's requirement that post-development discharge not exceed pre- development peak discharge. Surface discharges from the system will occur infrequently, perhaps every 80 years. Currently there is about one-half inch of direct surface runoff annually. Since surface runoff is a primary source of pollutant transport, the elimination of this runoff will have a beneficial effect on the estuary. The system will not degrade the quality of surrounding estuaries or the OFW since discharges to the estuaries will not occur from the ponds except under extreme conditions, and also because of the high level of treatment which will be provided by the ponds. Reasonable assurance has been given that water in the ponds will meet Class III standards, as well as the "free from" standards in Chapter 17-3, Florida Administrative Code, in the immediate future. The proposed ponds will be an improvement over existing borrow pits and bogs on the Island which have drastic side slopes and very long residence times, such as the Osmunda Bog, and will be a better habitat for fish and drinking water source for wildlife than the existing pits. It will also result in an improvement to Blue Pond, with better vegetation and habitat than currently exists, and with wildlife access being insured through preservation areas. A recognized and accepted ground-water flow model was used by Fairfield, and was approved by the District for use in this situation. The surficial aquifer system was correctly modeled as a single layer unit. Clay which underlies the Island is not a significant feature since, at minus 18 feet mean sea level, it is well into the saturated zone of the surficial aquifer and well below the surface water table, and since water levels actually observed in test wells could not be predicted when the top of the clay layer was used in the model as the bottom of the surficial aquifer. When the depth of the surficial aquifer was set at the top of the Hawthorne layer, the model accurately predicted water levels, as correlated against actual measured levels. Surface waters around Fort George Island have been classified as OFW since 1979. No significant development has taken place on the Island since 1979, and therefore ambient water conditions in 1978 and 1979 could reasonably be expected to have been what they are today. The stormwater management system will create a ground- water divide around the retention ponds. Any water falling inside the divide will flow toward the ponds; water falling outside the divide will percolate to the water table and then flow to the estuary. While under existing conditions nutrient pollutants that reach the water table simply flow to the estuary, after development half of the water falling on the golf course will be inside the divide and will therefore flow to the ponds. Therefore, after development there will be less nutrients and other pollutants reaching the estuary than under current conditions. Fairfield's stormwater management system is designed in a manner to ensure that the first 1 1/2 inches of rainfall will be retained or detained from an OFW. In fact, it appears that the system will actually retain runoff from the first 11 inches of rainfall. After analyzing data for metals, nutrients and coliform bacteria, it is found that the ambient water quality of the estuary will not be degraded by Fairfield's proposed development, and in fact there will actually be a net improvement in the quality of water reaching it from the Island. As a result of pollutant removal through filtration, sedimentation, absorption, precipitation, biological activity and dilution, it can reasonably be expected that ground-water seepage from the fairways and ponds to the OFW will meet primary and secondary drinking water standards, as well as Class II standards, and will not degrade the ambient water quality of the estuary. Infrequent surface discharges to the estuary also will not violate Class III standards. Total loading of nutrients to the OFW under developed conditions will be less than under existing conditions, and coliforms reaching the OFW via ground- water will be eliminated. Freshwater surface flow from the developed areas of the Island to the sloughs on the western side of the Island will be virtually eliminated. This elimination will not be detrimental to either salinities or particulate flows to these sloughs. Since there is an average of 50 inches of rainfall on the estuary per year, as opposed to less than 1/2 inch of freshwater runoff, and since the tidal flow is the forcing function in the estuary and not fresh surface water runoff, the salinity levels in the estuary will be largely unchanged. Particulate material will continue to be readily available to the sloughs from the marshlands, and from perimeter buffers which will be preserved by Fairfield around the Island. An undeveloped, preserved buffer zone is retained between the project and the surrounding waters as well as Rollins Sanctuary. This buffer zone is not intruded upon by the retention ponds contouring or berms associated with the development. In addition to the buffer zone, an undisturbed area will also be retained in the development, and the total acreage of the buffer and undisturbed areas will be 226 acres. The buffer and undisturbed areas will be more than adequate to protect the rare, notable, endangered or threatened plant and wildlife species identified on the Island when these areas are considered in relation to Rollins Sanctuary and other properties on the Island in state ownership. There will also be no construction activity in the saltmarsh off the western side of the Island. Extensive surveys conducted by Fairfield identified 26 species of plants and 16 species of wildlife on the Island. The habitat for all but one wildlife species, the gopher tortoise, is the saltmarsh to the west of the Island which will be undisturbed. Two national champion trees were identified and will be preserved. There will be no adverse impacts on notable plants in Rollins Sanctuary or other preservation areas since a 30 meter buffer is provided on the northern boundary of the Sanctuary and no development at all will take place to the west! of the Sanctuary. Woodstorks, the only endangered species identified in the survey, have been observed resting in trees at the western side of the Island in the saltmarsh. They are not nesting on Fort George Island, but return to the D-Dot Ranch south of Jacksonville every night to nest. The western area of the Island will remain undisturbed habitat in a buffer area from 250 to 450 feet wide, as will the southwestern portion of the Island. Woodstorks appear to be using the tidal sloughs for feeding, and development should have no adverse impact on these sloughs. A heron and egret rookery exists on the northern side of the Island, primarily off of Fairfield's property. Approximately 20 nesting pairs of great blue herons and great egrets use this rookery, which appears to be a satellite of regional rookeries. These are not notable species, but Fairfield will provide up to a 600 foot buffer. The gopher tortoise is the only notable terrestrial species on the Island and is a "species of special concern." The undisturbed natural habitat of a major concentration of gopher tortoise on Fairfield's property will be preserved. While the habitat for non-notable species such as bobcat, grey fox, owls and songbirds will be reduced, they will not be extirpated. Significant archaeological sites on Fairfield's property will be preserved and protected, including Mission San Juan del Puerto, the Grave Robbers Mound, the Sugar Mill site, and the Crypt site. If additional sites are found during development, a mitigation plan will be developed for approval by the State Division of Archives, with an evaluation by a professional archaeologist. Indian middens, or trash piles, have been deemed insignificant and will not be preserved. Surface water table draw-downs which will result from Fairfield's system due to pumping from the surficial aquifer will have no adverse impact on either wildlife or plant life on the Island. Such draw-downs will be limited and localized primarily around the ponds. In fact, the water table on the western side of the Island may increase slightly. The draw-down within Rollins Sanctuary or at Rollins Creek will be less than one foot and therefore should not have any adverse impact. Rollins Creek is approximately five feet wide. A fifty foot buffer around the Creek is provided. Only EPA approved chemicals will be used for weed control associated with the ponds, and aeration will be used to assist the production of oxygen in the ponds. Nutrients, nitrates and phosphorous, will be continually analyzed so that immediate corrective action in fertilizer application can be taken if necessary. Fairfield will utilize an integrated pest management program under a plan which must be approved by the District and which will actually reduce the need for chemical pesticides. Only EPA approved pesticides will be used. As for fertilizers, Fairfield will apply fertilizers more frequently, but in lesser amounts, than on the existing golf course. This ensures a better uptake of nitrates and phosphates, thereby reducing unabsorbed nutrients that might flow to the ponds or estuary. A full-time resource manager will be employed to ensure proper operation of the entire stormwater management system. Once the system is in place, Fairfield will conduct a long-term monitoring program of the water quality in the MWBZ, surficial aquifer, the ponds, and any surface water discharges to ensure permit compliance and also to provide a data base for further activities. Such a data base will represent a positive public benefit. Additional beneficial results of the project, after construction permits are obtained, include stabilization of the northern shoreline of the Island which has had notable marshland erosion, and re-aligning a road on the western side of in the Island to eliminate a point where it crosses Big Slough and thereby open the Slough up to additional sheetflow. Middle and Northern Sloughs will be preserved. Mitigation will be required for any disturbance of a small wetland area on the west side of the Island which is approximately 3/4 of an acre in size. Eliminating marsh erosion, and removing vehicle traffic and flow restrictions in the area of Big Slough are clearly in the public interest, as is the preservation of other wetland areas. The District staff originally recommended that Fairfield's MSSW application be denied but after modifications to the application were made, the District staff has recommended approval with conditions to ensure generally that Fairfield: Monitors water quality in the five ponds in accordance with a plan approved by the District, as well as the quantity and quality of all surface water discharges. Monitors water levels in surficial aquifer wells and reports such data to the District Recalibrates its surficial aquifer and water budget models every five years using the actual monitoring data it has collected and reported to the District in the preceding years, and if such recalibration indicates more than a 50% increase in the volume or frequency of surface water discharges, the stormwater management system must be altered, with District approval, to prevent such increases Submits a pesticide management plan for District approval. Submits a mitigation plan for District approval, at the time of application for construction permits, that will mitigate for any loss to off-site aquatic and wetland dependent species associated with project development in the area of the tidal sloughs on the west coast of the Island. A total of fourteen specific conditions which the District staff recommends be placed on the conceptual approval of the MSSW permit are contained in the Management and Storage of Surface Waters Summary Sheet, dated May 1986, which is hereby incorporated by reference and found to be reasonable in its entirety. Case Number 85-3596 (CUP) The following findings of fact are based upon the stipulation of the parties and relate to Fairfield's CUP application: The District, a special taxing district and agency, created by Chapter 373, is charged with the statutory responsibility for the administration and enforcement of permitting programs pursuant to Sections 373.219 and 373.223, Florida Statutes, and Chapter 40C-2, Florida Administrative Code. The District is the agency involved in this proceeding. The District has assigned Fairfield's CUP application the permit number 2-031-0021AN. Findings of Fact 10, 11, 14 and 15 which are set forth above are hereby readopted and incorporated herein. On December 1, 1983, Fairfield, through its then-agent George Register, III, submitted to the District the subject CUP application. The application was assigned No. 2-031-0021AN. On August 23, 1985, the District gave notice of its intent to deny CUP application No. 2-031-0021AN. On September 23, 1985, the District determined to recommend issuance of CUP application No. 2-031-0021AN, as then modified, with conditions. Fairfield had originally contemplated in both its original Master Resource Management Plan (MRMP) and the referenced CUP application that its proposed development for Fort George Island would have a 36-hole golf course facility. Fairfield subsequently reduced its proposed golf course facility from 36 holes to 27 holes. The City of Jacksonville's Planning Commission approved the MRMP with conditions, including the condition that the golf course be reduced, on January 29, 1986. Because of the reduction in size of Fairfield's proposed golf course facility form 36 to 27 holes, Fairfield's total requirements for irrigation water were reduced. By pleading dated February 28, 1986, Fairfield moved to amend its application. The motion was granted by the Hearing Officer on March 11, 1986. In light of this amended application, the District issued a revised "Consumptive Uses of Water Summary Sheet," dated March-24, 1986, to reflect this amended request and to recommend issuance of the CUP. The Petitioners' original Petition For Formal Administrative Proceedings was timely filed within fourteen (14) days of receipt of the District's proposed agency action of September 23, 1985. A number of the members of Friends of Fort George, Inc. own real property on Fort George Island, reside on the Island, and possess drinking water wells on the Island and engage in recreational activities on the Island and its adjacent waters and environs. The subject matter of the proposed agency action challenged by Petitioners and Intervenors concerns the water resources on Fort George Island, including its drinking water supply. Protection of this resource falls within the general purpose and objectives of Friends of Fort George, Inc., namely, the preservation, conservation and restoration of Fort George Island and surrounding environs. The relief requested in this proceeding by Petitioner and Intervenor is denial of the proposed consumptive use permit. The water storage ponds proposed in the project will intersect with the surficial aquifer on Fort George Island. The residential value of Petitioners' property on Fort George Island would decrease if the property had absolutely no access to potable water. Petitioners and Intervenors have standing pursuant to Section 403.412(5), Florida Statutes, to bring this action. The following findings of fact relating to Fairfield's CUP application are based upon the evidence presented, including the demeanor and credibility of witnesses who testified: Following review of Fairfield's CUP application, District staff requested additional information on January 11, 1984; Fairfield developed a plan of study to supply the requested additional information, and the plan of study was approved by District staff. The plan of study sought to find out the nature and characteristics of an anomaly in the northeastern part of the Island, and also to determine if Fairfield's proposed usage would have any affect on existing legal users. As part of the study, Fairfield conducted a well inventory and survey, water quality survey, water level measurements, and vertical investigations. The study also examined three alternatives to obtaining water from the various water bearing zones under Fort George Island, including drilling a test well (TP-2) into the Middle Water Bearing Zone after obtaining appropriate permits. The Floridan Aquifer below Fort George Island consists of three zones--The Upper Water Bearing Zone (UWBZ), Middle Water Bearing Zone (MWBZ) and Lower Water Bearing Zone (LWBZ). The bottom of the Hawthorne formation separating the surficial and Floridan aquifers occurs at about 400 feet below mean sea level. The UWBZ exists from of depth of approximately 520 feet to 1000 feet. Below the UWBZ is an upper semiconfining zone from a depth of approximately 1000 to 1200 feet. The MWBZ is generally 100 feet thick and exists from a depth of approximately 1200 to 1700 feet, below which is a lower semiconfining zone from a depth of approximately 1700 to 2000 feet. The MWBZ is a single water producing zone with interconnected channels or flow zones. The LWBZ exists from a depth of approximately 2000 to 2100 feet, below which is a lower confining unit. The confining zones are saturated with water but are less permeable than any of the water bearing zones. Regional ground-water flow in the Floridan Aquifer at Fort George Island is from the west to the east, northeast and southeast. Water quality to a depth of approximately 1900 feet is generally good, with chloride concentrations of less than 50 milligrams per liter (mgl). In the UWBZ chloride concentrations are generally 10-15 mgl. However, in the north eastern part of the Island chloride concentrations are approximately ten times higher, although still considered potable, due to an anomaly which exists in this area with a radius of approximately 1000 feet, and which allows the flow of water directly from the LWBZ to theMWBZ and LWBZ. While the potentiometric surface or pressure for most of the Island is 39 feet, at the anomaly it is 43 feet above mean sea level. The anomaly was caused either by a sinkhole or fault and acts as a localized conduit or coins source of lower quality water from the LWBZ to the UWBZ. No other point sources of lower quality water exist on the island. The Hawthorne formation was found to exist approximately fifty feet deeper in the area of the anomaly than on the rest of the Island. Existing users on Fort George Island draw water from the UWBZ. Fairfield proposes to draw its water from the MWBZ at a rate of 101.11 million gallons per year in an average year, and 181.04 million gallons per year in a 1 in 10 dry year, and will be the only user of water from the MWBZ on the Island. Household use consumption is projected to be 129.3 gallons per capita which is below the District average of 150 gallons per capita. Based upon pump tests already conducted by Fairfield, the MWBZ will produce more than enough water to meet Fairfield's needs for its project and such pumping will have no adverse impact on the UWBZ or existing users. Pumping from the MWBZ will also have no adverse impact on the MWBZ. Specifically, salt water intrusion from the surrounding estuary or from the tWBZ to the MWBZ will not significantly increase, chloride levels will not increase and potentiometric levels will not decrease in the MWBZ due to this pumping. The MWBZ will produce an adequate Supply of potable water for 15 to 30 years. Fairfield does propose to use well P-1 in the UWBZ in emergency situations but such usage will have no adverse impact on the quality of the UWBZ or its existing users. Use of the MWBZ will be minimized by maximum utilization of the surface water management system ponds for irrigation needs. Well TP-2 is approximately a mile from the anomaly in a south-southwesterly direction. It was constructed by Fairfield, after obtaining necessary permits, with casing to a depth of 771 feet all the way through the UWBZ and into the underlying confining bed. Pump tests were conducted on the MWBZ using TP-2, which is the only well on the Island in the MWBZ. No separate monitoring well in the MWBZ was required by the District, and none was utilized by Fairfield because the flow off 2,000 gallons per minute from TP-2 was so strong that a separate monitoring well was not necessary. When TP-2 was pumped, there was no measurable change in nearby UWBZ wells. This confirms that the MWBZ is hydrologically separate from the UWBZ, other than at the anomaly, and pumping from one will not affect wells in the other. In response to a request from the District, Fairfield utilized conservative factors in applying a mathematical model to determine the effects of its proposed pumping on the Floridan Aquifer. Using the USGS contaminant transport model, which is professionally accepted and appropriate for use in this case, and after proper calibration to reproduced observed conditions, it was determined that chloride concentrations in the MWBZ will not be adversely affected, nor will potentiometric surfaces of the UWBZ or MWBZ when pumping is conducted from TP-2 in the MWBZ over a thirty year period. At most, pumping from TP-2 could result in a slight increase of flow from the anomaly into the MWBZ, with a minimal increase in chloride concentrations. Fairfield has agreed to install a monitoring well in the MWBZ and to monitor several wells in the UWBZ in order to constantly test and monitor chloride levels. Currently chloride levels in the MWBZ are 25 mgl and the limit for potable water is 250 mgl. The monitoring well will be approximately 550 feet northeast of well TP-2, and will detect any changes in chloride levels with sufficient lead time for Fairfield to initiate action to drill another well into the MWBZ further from the chloride source. It is estimated that such lead time could reasonably be as much as ten years. Even without Fairfield's pumping from the MWBZ, water quality in the UWBZ would be expected to degrade, as it has historically, as a result of regional pumping which has caused a regional decline in water quality and 37 SO as a result of flow from the anomaly. Existing users may actually benefit from Fairfield's pumping from the MWBZ and the decline in the quality of the UWBZ may be slowed due to Fairfield's elimination of golf course irrigation which currently comes from the UMBZ at a rate of approximately 175,000 gallons per day, accounting for approximately 90% of all current water usage on the Island. Pumping from the Floridan Aquifer will be conducted to supplement irrigation from the stormwater management system. Fairfield will use up to 580,000 gallons per day for golf course irrigation in dry years. However, even in a dry year the primary source for golf course irrigation will still be from the stormwater management system. In an average year, approximately 95% of irrigation needs will be met by the surface water management system ponds. In a wet year there should be no need to pump from the Aquifer. The District staff originally recommended denial of Fairfield's CUP application when it was for a 36 hole golf course, anad for withdrawal of potable water from the UWBZ with only golf course irrigation being from the MWBZ. Fairfield has modified its application and now proposes a 27 golf course with all water needs coming from the MWBZ, except in an emergency when well P-1 in the UWBZ may be used. The District staff has now recommended approval, with a total of twenty conditions contained in the "Consumptive Uses of Water Summary Sheet," which are hereby incorporated by reference and which ensure generally that Fairfield: Mitigates any adverse impact caused by withdrawals permitted herein on existing legal uses of water; the District may curtail any withdrawal if there are adverse impacts on existing legal users. Mitigates any adverse impacts caused by withdrawals permitted herein on existing adjacent land uses; the District may curtail any withdrawal if there are adverse impacts on existing adjacent land uses. Must reapply for another CUP after seven years from issuance. Begins irrigating the existing 18 hole golf course from the MWBZ by March 1, 1987, with existing UWBZ irrigation wells only to be used thereafter for fire protection. Institutes a sampling program for existing wells in the UWBZ and MWBZ. Supplies all potable and supplemental irrigation requirements from the MWBZ, and keeps monthly records of such withdrawals. Drills and maintains a monitoring well in the MWBZ approximately 550 feet northeast of its MWBZ potable and supplemental irrigation well, and provides long term water quality samples to the District from the monitoring well. The District staff's recommended conditions are found to be reasonable in their entirety.
Recommendation Based on the foregoing, it is recommended that the St. John's River Water Management District issue to Fairfield Communities, Inc., conceptual approval of MSSW permit number 4- 031-002AC with conditions set forth in the District's Management and Storage of Surface Waters Summary Sheet, dated May 1986, and also issue to Fairfield Communities, Inc., CUP number 2-031- 3021AN with conditions set forth in the District's Consumptive Uses of Water Summary Sheet. Further, it is recommended that the Florida Wildlife Federation be dismissed as a party in this proceeding. DONE and ENTERED this 6th day of October, 1986, at Tallahassee, Florida. DONALD D.

FAIRFIELD COMMUNITIES, INC., and ST. JOHNS RIVER WATER MANAGEMENT DISTRICT, Respondents. /
The Issue The issue in this case is whether the Southwest Florida Water Management District (District) should issue to Century Realty Funds, Inc. (Century) Environmental Resource Permit (ERP) No. 44000227.002 (the ERP), which would modify Management and Storage of Surface Waters (MSSW) Permit No. 400227.000 (the Permit) and Stormwater Exemption No. EO1481, issued by the District to Century in July 1985 for construction of a surface water management system for Angler's Green Mobile Home Park located in Mulberry, Polk County, Florida.
Findings Of Fact The District issued Management and Storage of Surface Waters (MSSW) Permit No. 400227.000 and Stormwater Exemption No. EO1481 to Century in July 1985 for construction of a surface water management system for Angler's Green Mobile Home Park (MHP) located in Mulberry, Polk County, Florida. Angler’s Green MHP Angler’s Green MHP is an 83-acre residential golf course development of approximately 385 homes located off of State Road 37 near Mulberry. Residents at Angler’s Green own their own mobile homes and lease the residential lots pursuant to annual leases expiring December 31 of each year, with guaranteed renewal conditioned upon owner compliance with the terms and conditions of the lease. Prior to being developed as a mobile home park, the property which is now Angler’s Green MHP was part of a phosphate mining operation and was reclaimed under a phosphate mining land reclamation plan approved by the Florida Department of Natural Resources and a reclamation contract dated September 4, 1984. Final contours of the Angler’s Green site were made in accordance with the approved reclamation plan. After reclamation contouring, a 23-acre manmade (former phosphate mine pit) lake remained in the northeast quadrant of the Angler's Green site. The resulting lake had a finger arm (bay or cove) extending from the southwest corner of the main body of the lake, oriented in a north-to-south direction and located west of a peninsula of land extending into the northwest part of the lake from the north. The lake also had a short, narrow canal leading into the main body of the lake from the south; the canal connected at a right angle to longer narrow waterway to the south of and extending parallel to the main body of the lake in an east-to-west orientation. There also were two smaller ponds on the property after reclamation contouring. After reclamation, surface water onsite generally flowed westerly and discharged from the property to a railroad ditch along the western boundary of the property. The recorded post-reclamation, pre-development water level for the 23-acre lake, as indicated on the site grading plans, was around 127.1 to 127.8 feet above Mean Sea Level (M.S.L.). The 1985 Permits On July 10, 1985, the District issued MSSW Permit No. 400227.000 and Stormwater Exemption No. EO1481 to Century to authorize the construction of a surface water management system for Angler’s Green. The MSSW Permit had an expiration date of July 10, 1988. As designed, the permitted Angler’s Green surface water management system was to route internal stormwater runoff to swales, detention ponds, and catchment areas before discharging through a sidebank sand filtration system (a berm approximately 300 feet long containing an 8” perforated drain pipe covered by a filter fabric and sand filter material) to receiving waters at the northwest corner of the property. The permitted system was designed with five drainage areas known as Basins A through E. Basin A was in the southeast quadrant of the site; Basin B was to its east in the southeast quadrant of the site; Basin E was to the north of Basin A and included the 23-acre former phosphate mining pit reclaimed as an artificial lake, which was referred to as “Lake E” or sometimes “Pond E"; Basin C was to the west of Basin E; and Basin D was to the west of Basin C and to the north of Basin B. The two smaller ponds on the property were designated Pond C-1 and Pond B-1 and were located in Basin C and Basin B, respectively. Basin D was in the northwest corner of the site; the discharge structure was in the northwest corner of Basin D. As the system was designed, stormwater from Basin E would appear to sheet flow naturally into Lake E; stormwater from Basin A would appear to flow naturally to the southwest, away from Lake E, but the system routed the water from the southwest corner of Basin A to the western end of the waterway on Lake E through an underground pipe. Stormwater from Basin B was to flow to and be retained in Pond B-1; as the system was designed, surface water was not designed to discharge offsite from Basin B. As designed, Lake E served as a detention pond for water from Basin E and Basin A. It was to have a control structure (CS-1) in the arm of Lake E that would produce a seasonal fluctuation range of two feet, from 127.5’ above M.S.L. to 129.5’ above M.S.L. Stormwater discharging from CS- 1 was to be conveyed by pipe to Pond C-1, where it was to mingle with surface water draining from Basin C. When full, Pond C-1 would cascade into the golf course area in Basin D and, as necessary, in a portion of Basin B. After catchment and detention in the golf course area, overflow was eventually and ultimately to discharge offsite through the side-bank sand filtration system in the northwest corner of Basin D. In this manner, the Angler’s Green surface water management system was designed to accommodate the 24-hour, 25- year storm event, which was estimated to produce approximately 8 inches of water in a 24-hour period. It also was designed to comply with the water quality requirements as specified in Florida Administrative Code Chapter 17-25 (1985 Ann. Supp.) by detaining the first half-inch of runoff before discharging it offsite through the sidebank sand filtration system in the northwest corner of Basin D. (All rule citations are to the Florida Administrative Code.) Omission of the Stangls During the review process, the District noted from drawings submitted as part of Century's MSSW Permit application that the project area did not include approximately the eastern third of the main body of Lake E. District staff brought this to Century's attention in a request for additional information (RAI) and stated: "If possible, you should obtain a perpetual right to operate and maintain the lake from other owners." In response, Century falsely represented to the District that L. Kirk McKay, a joint venture partner of Century, was the only riparian owner on Lake E and that Century had obtained from him a perpetual right to operate and maintain Lake E as part of the MSSW Permit. In fact, the Stangls owned property on the east side of the lake, including approximately 500 feet of lakefront and contiguous lake bottom. The Stangls and two partners purchased the property from McKay himself in 1979. The Stangls bought out their partners in 1984. The District relied on Century's misrepresentation. The District would not have issued the MSSW Permit to Century if the District had known that Century did not own or control all the land being used for the Permit--specifically, including all of Lake E. See Rule 40D-4.101(1)(d) and (2)(d)6. (1985) (application must include "evidence of ownership or control"). In addition, because the District was unaware of the Stangls' ownership of a portion of Lake E, the District did not require Century to give the Stangls direct, actual notice of the Century's permit application. Instead, the District only required that Century publish notice of the District’s receipt of the permit application. Notice was published on April 3, 1985, in the Lakeland Ledger, a newspaper of general circulation qualified under the terms of Section 50.011, Florida Statutes. But the Stangls did not see the published notice, were unaware of the permit application, and did not ask to participate in the permitting process. The Stangl property adjacent to Angler’s Green remained undeveloped and unoccupied until 1999, when the Stangls' son, John, established a business on the site. Prior to 1999, the Stangls visited the property a couple times a year. They were fully aware of the construction and operation of Anglers Green as a mobile home park across Lake E. During this time, Century leased 385 lots with guaranteed annual renewal conditioned only upon compliance with lease terms and conditions. Amenities under the leases included clubhouse and golf course privileges. At no time before 2000 did the Stangls take any action to challenge the validity of Century's 1985 MSSW Permit. 1985 Surface Water Management Permitting Requirements In 1985, permitting requirements for surface water management systems were divided between two regulatory schemes. Surface water management permits in Polk County were issued by the District under Chapter 373, Florida Statutes, and Rule Chapters 40D-4 and 40D-40, which addressed water quantity and flooding issues for projects greater than and less than 40 acres, respectively. Water quality permits or exemptions from water quality permitting requirements were issued by the Department of Environmental Regulation under Chapter 403, Florida Statutes, and Rule Chapter 17-25 to address water quality concerns. It was not until 1988 that permitting requirements were consolidated into the MSSW regulatory program administered by the District under Rule Chapters 40D-4 and 40D-40. In 1985, the District did not have a Basis of Review (BOR) to specify system design requirements for applicants to provide reasonable assurances that the conditions for issuance of surface water permits were satisfied. Standards and criteria for the design and performance of surface water management systems were contained in Rule 40D-4.301(2) (1985) Under subsection (2)(i) of that rule, projects designed to meet the requirements of Chapter 17-25 [Regulation of Stormwater Discharge] were presumed to meet applicable State water quality requirements. There were no requirements for wet detention pond littoral zones. 20. Under Rule 17-25.03(2)(b) (1985 Ann. Supp.), stormwater management systems for projects with drainage areas less than 100 acres that provided retention or detention with filtration of the first half-inch of runoff were exempt from the permitting requirements of Rule Chapter 17-25. 21. In 1985, District Rule 40D-4.301(2)(j) (1985) allowed for natural areas and existing water bodies to be used for stormwater retention or detention purposes when not in conflict with environmental or public use considerations. Areas that could be considered for this purpose included previously-degraded areas or man-made areas (such as borrow pits). Apparently, the District allowed Century to use Lake E as a detention pond under this provision. Deviations from MSSW Permit Angler’s Green MHP was constructed in two phases, with the first phase completed in 1985, and the second phase completed in 1987. Construction of at least the part of the surface water management system to serve the first phase took place prior to 1985; it was not clear from the evidence whether construction of the part of the surface water management system to serve the second phase also took place prior to 1985, but it clearly took place prior to construction of the second phase in 1987. Condition No. 4 of Century's MSSW Permit required the submittal of a certification that the system was constructed in accordance with the approved and permitted design. But Century did not provide any such certification. Century also never certified to the District that its new stormwater discharge facility, as constructed, continued to qualify for exemption from State water quality requirements. Although the surface water management system was constructed and operating, the District never transferred the 1985 Permit to the operation phase. In several respects, the Angler’s Green surface water management system was not constructed as designed, approved, and permitted in 1985. The pipe to convey stormwater from the southwest corner of Basin A back to the Lake E waterway apparently never was constructed; instead, stormwater from Basin A was routed to Pond B-1. (There also was a berm constructed in Basin A near the southern boundary of the site; but that berm apparently was a visual berm, and there was no evidence that it affected performance of the surface water management system.) Control structure CS-1 (which was supposed to be located in the arm or bay of Lake E) and the pipe to convey overflow from there into Pond C-1 also never were constructed. By the early 1990's, Angler's Green was experiencing flooding in the golf course area in Basin D and B for extended periods of time. In November 1993, the District responded to a complaint of flooding in that vicinity. Upon investigation, the District determined that malfunction of the surface water management system serving Reservation Lakes (now known as Paradise Lakes), a development to the north and downstream of the Angler's Green system, was causing water to back up through the wetlands and the sand filtration system in the northwest corner of the Angler’s Green project. As a result, water overtopped the discharge structure, equalized at levels above the top of the discharge structure's berm, and flooded the golf course for extended periods of time. At some undetermined point in time, an unpermitted pond was dug in Basin D, apparently in an attempt to alleviate flooding of the golf course. In addition, possibly for the same purpose, a pump was installed in Basin D near Pond C-1, and a pipe was installed to convey stormwater from there into Lake E. The sidebank sand filtration system designed to provide filtration of stormwater prior to discharge from the northwest corner of the site does not appear to exist today. It may be present but difficult to see after 15 years of plant growth; or it may have been removed or disturbed as a result of re-grading in the area. However, the evidence proved that the discharge structure was present in 1993, and there is no reason to believe that it was not installed during construction of the surface water management system--i.e., by 1987 at the latest. In addition, at some undetermined point in time, a pipe was installed at the northeast corner of Lake E to convey overflow from Lake E eastward to a drainage ditch located alongside SR 37 to the north of the Stangls' property. No witnesses could testify as to when the pipe to the SR 37 ditch was installed or its elevation. (The District and Century state in their PRO that Map No. 2 in P/I Exhibit 14--an aerial map/survey submitted to the District by Century on August 13, 1990, as part of Century's 1990 Water Use Permit No. 209993.000 application--notes the pipe's elevation as 127.95 feet above M.S.L.; but no such finding could be made from review of the exhibit.) Roads in Angler's Green have inverted crowns to convey runoff from roads, driveways, and roofs away from mobile home lots. Some runoff from these impervious surfaces appears to be directed into a swale on the east side of the site; this swale leads to Lake E. In addition, approximately 12 drains have been installed in or near roads in Angler's Green that convey water through pipes directly into Lake E or Pond C-1. Under current Rule Chapters 40D-4 and 40D-40, road drains connecting impervious surfaces to Lake E would have to be shown on application construction drawings, and separate stormwater calculations would have to be provided in an application. But in 1985 this was not required. Century's calculations, together with flow arrows on drawings showing the direction of stormwater flow towards the detention ponds, were considered sufficient--especially since Century's calculations used a relatively high runoff co-efficient. As a result, the existence of these drains and pipes are not considered to be substantial deviations from the original, approved design. Similarly, approximately 64 roof drains and pipes conveying water from roofs directly into Lake E and Pond C-1 would not be considered substantial deviations from the original, approved design. In addition, these apparently were installed by mobile homeowners over the years, not by Century. From 1985 to 2000, the District did not have occasion to address regulatory concerns at Angler’s Green, except for the complaint of flooding in the golf course area that occurred in November 1993 and a more recent complaint about an area of the golf course that was designed to flood under certain conditions. Otto Stangl’s Complaint and the District’s Response Around November 1999, John Stangl noticed a fish kill in the ditch along SR 37 near the Stangl property. He also was contacted by a governmental compliance officer concerning the fish kill. Upon investigating, John Stangl saw the unpermitted pipe leading from Lake E that was discharging into the SR 37 ditch where the fish kill was observed, as well as the unpermitted pump that was pumping water from the Angler’s Green golf course area through a pipe that discharged into Lake E. In February 2000, Otto Stangl complained to the District about the fish kill and the existence of the unpermitted structures associated with Lake E. Upon receiving Otto Stangl’s complaint, District staff conducted site visits of the Angler’s Green project. Staff observed the unauthorized pump and pipe conveying water from Pond C-1 to Lake E and the unauthorized pipe conveying water from Lake E to the SR 37 ditch. Staff also observed that the Lake E control structure was missing, the pipe to convey stormwater from Basin A to Lake E was missing, and Basin D had been re-graded. In February 2000, the District also became aware of the fact that Century did not have full ownership or control of Lake E. On March 15, 2000, the District issued Century Notice of Non-Compliance and directed Century to either construct the system as designed and permitted or to seek a permit modification. On May 8, 2000, Century submitted a letter application to modify the original MSSW Permit No. 400227.000 by constructing the originally permitted Lake E control structure and pipe conveying water from Lake E to Pond C-1, but in a different location in Lake E than originally permitted due to the existence of homes at the location where these structures were originally planned. The application was subsequently amended to be a formal modification upon Century’s request for further modification to allow Basin A stormwater to flow to Pond B-1 and to expand Pond B-1 and add a control structure and an effluent filtration system. Despite having actual knowledge since at least February 2000 that the Angler's Green surface water management system was built partially on their property, the Stangls did not ask for a hearing on the 1985 Permit. Instead, they awaited the District's consideration of Century's modification application and sought to challenge the District's notice of intent to grant the modification permit issued on October 29, 2001. The District’s Regulatory Compliance Practices In the 1980's, the District appeared to pay little or no attention to construction of permitted projects or submission of required post-construction certifications. Many projects permitted by the District in the 1980’s, such as Angler’s Green, were built and operating although no certifications had been submitted; as a result, the permits issued for these projects never were transferred to the operation phase. Eventually, some projects not built in compliance with issued permits came to the attention of the District, typically through third-party complaints about drainage problems and flooding. By this time, there was a large backlog of issued construction permits for which no required post-construction certifications had been submitted. The backlog of these older projects was so large that the District decided not to initiate an aggressive, systematic, and comprehensive review of all permits for which no required certifications had been submitted. Instead, projects were checked on an ad hoc basis as complaints regarding the functioning of their surface water management systems were registered. When it came to the attention of the District in this manner that a project had been built under an MSSW permit but that no required certifications had been submitted, the District first attempted to secure the required certifications in the form of certified as-built construction drawings and a Statement of Completion, as required by BOR 2.7. In so doing, it was common practice for the District to accept certifications beyond the expiration date on a permit. If projects were substantially completed, the District would not deem the permit as expired simply because the required certifications had not been submitted before the expiration date; and such projects did not lose their status as being permitted. It should be noted that, according to the testimony of the District's expert, William Hartmann, this agency practice was not based on an interpretation of Rule 40D- 4.321(1)(b) (1985) (on duration of construction permits). Rather, the agency practice was to ignore the expiration of the construction permit under those circumstances. In addition, it does not appear from the evidence that the District ever before has faced the situation presented in this case--where a person on whose property part of a surface water management system was built without the person's consent opposes modification and asserts the construction permit has expired. In cases where the agency's practice was applied, if the required certified as-built construction drawings and Statement of Completion could not be provided because the project was not built in accordance with the MSSW permit, the District would require the permittee to either bring the system into compliance with the approved permit designs or obtain a modification of the construction permit. Letter modifications would be accepted when the requested modification would not substantially alter the permit authorization, increase the authorized offsite discharge, impact the environmental features of the project, decrease the required retention/detention, decrease the required flood control elevations for roads or buildings, or decrease pollution removal efficiency. See Rule 40D-4.331(2)(b) (1985). (The current version of the rule adds renewal or extension of the existing permit duration.) Alterations meeting the threshold requirements for a letter modification would be presumed to meet the conditions for issuance for a permit. Otherwise, formal permit modifications would be required. When application is made for a permit modification, the District’s practice is to evaluate those aspects of the surface water management system being modified. Review generally would not extend to the entire system. Permittees seeking to modify their surface water management systems generally are not required by the District to bring the unmodified portions of the system into compliance with current design criteria. Proposed ERP Permit Modification ERP Application No. 44000227.002 seeks authorization to modify portions of the Angler’s Green surface water management system. The specific alterations for which approval is sought are: permanent removal of the existing, unpermitted 18-inch pipe between Lake E and SR 37 roadside ditch; permanent removal of the pump and associated piping conveying water from Pond C-1 to Lake E; installation of the control structure (CS-1), together with installation of pipe to convey water from the control structure to Pond C-1, as designed and approved in the 1985 Permit but different location in the northwest corner of the main body of Lake E; re-grading of the northwesterly portion of the golf course to more closely conform to the original permitted plan and help keep Basin B separate from Basin D; reconstruction of the side-bank sand filter system in the northwest corner of the property, as designed and approved in the 1985 Permit but with a slightly higher invert elevation (122.04 feet above M.S.L.) to prevent water from backing up into Angler's Green from Paradise Lakes again, and with a concrete flume and spreader swale between Pond C-1 and the berm of the side-bank sand filter system; enlargement of Pond B-1; installation of a control structure on Pond B-1; and installation of 100 feet of 6-inch side-bank sand filter discharging to the southwest corner of the property from Pond B-1. By removing the unpermitted pipe to the roadside ditch along SR 37 and by constructing control structure CS-1, with the same control elevations as in the 1985 Permit (albeit at a different location in Lake E), and connecting CS-1 by pipe to Pond C-1 as envisioned in the 1985 Permit, the function of Lake E should approximate its function under the design approved in 1985. Modifying the permitted design to authorize Basin A to flow to Pond B-1 instead of Lake E results in less water flowing to Lake E; these changes will not increase water quantity or quality impacts to Lake E, as compared to the 1985 Permit. As compared to reclamation conditions prior to implementation of the 1985 Permit, water quantity and quality impacts to Lake E would be expected both under the system as designed and permitted in 1985 and as proposed to be modified, by virtue of the similar use of Lake E as a detention pond under either system. Pond B-1 is being enlarged to better accommodate the flow from Basin A. The control structure being added at Pond B-1 will control flow into the swale to the west so as to address water quantity impacts in that area. Stormwater calculations for the revised Pond B-1 demonstrated that the post-development discharge rate will not exceed the pre- development discharge rate, so that there are no concerns for adverse water quantity impacts to receiving waters or adjacent lands or flooding impacts to on-site or off-site property. The historical flows to the west are still maintained. The discharge structure being added at Pond B-1 will account for treatment of the Basin A flow. Based on calculations for revised Pond B-1, the enlarged pond will retain and percolate half an inch of stormwater runoff from the contributing area in 36 hours (which is consistent with current BOR design requirements). The proposed Pond B-1/Basin B modifications, including the routing of Basin A stormwater to Pond B-1, will not adversely affect the quality of receiving waters in that vicinity such that state water quality standards would be violated. Angler's Green is located in the Southern Water Use Caution Area of Polk County. No surface or groundwater levels or surface water flows have been established for this area under Section 373.042, Florida Statutes. The proposed modifications do not involve any works of the District. The proposed modifications are based on generally accepted engineering and scientific principles and employ treatment methods of effluent filtration which involve commonly accepted designs that can be effectively performed and function as proposed. There are no concerns about Century’s financial, legal, or administrative capability to undertake the proposed modifications as specified in the permit, if issued. There are no applicable special basin or geographic area criteria established for this area. Environmental Concerns As with its review of the proposed permit modification for water quantity impacts, the District's review of environmental concerns was limited to review of impacts from the proposed modifications to the original permitted design; unmodified portions of the original permit were not reviewed for compliance with current requirements. An approximately 20 square-foot permanent impact is proposed to Lake E due to the placement of the control structure (SW-1) in the water. A 379 square-foot temporary impact is proposed to Lake E due to the placement of a cofferdam to facilitate construction of the control structure. Temporary impacts to Lake E resulting from the construction of the control structure would be addressed through the use of sediment and erosion controls to prevent possible sedimentation and turbidity that may arise during the construction activity. The placement of a control structure in Lake E would create very minor permanent impacts resulting from the loss of the footprint of the control structure. These impacts would be insignificant. Due to the very minor nature of these proposed impacts, no mitigation would be required, and no loss of wetlands would be required to be recorded on the Wetlands/Surface Water Table. Construction of SW-1 would not adversely impact the value of functions provided to fish and wildlife, and listed species including aquatic and wetland dependent species, by wetlands, other surface waters and other water related resources of the District. No secondary impacts would be expected from construction of SW-1. No unacceptable cumulative impacts upon wetlands and other surface waters would be expected to occur as a result of construction of SW-1. The project area includes .71 acre of herbaceous/forested wetlands (WL-1) in the northwest corner. The potential for secondary impacts is addressed by an existing fence surrounding WL-1, which eliminates concerns for secondary impacts to this wetland area. No adverse impacts would be anticipated to occur to these wetlands, and no adverse secondary impacts to the water resources would be expected to occur as a result of the proposed modifications themselves. The proposed modifications would not cause unacceptable cumulative impacts to wetlands and other surface waters. Class II or Class III waters would not be affected by the proposed modification project. Therefore, Rule 40D- 4.302(1)(c) is not applicable. No seawalls, lagoons or estuaries are involved in this project. Therefore, Rule 40D-4.302(d) is not applicable. The proposed modifications would not be contrary to the public interest. Relocation of a control structure and enhancement of the Basin B portion of the system would create no significant change in impacts. The proposed modifications constitute a slight improvement over water quality from the original permitted design. No threatened or endangered species were identified for Angler’s Green. The proposed relocation and construction of the Lake E control structure, preservation of onsite wetlands in the northwest corner, and re-design of Pond B-1 present no environmental concerns. Consequently, the proposed modifications do not create any potential for adverse effects regarding the conservation of fish and wildlife, including endangered or threatened species or their habitats. The proposed modifications do not adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity. The project area does not involve navigable waters and does not affect the flow of water or cause harmful erosion or shoaling. Hence, Rule 40D-4.302(1)(a)(3) does not apply to this permit modification application. There are no significant historical and archaeological resources involved in this Project. Therefore, Rule 40D-4.302(1)(a)(6) is not applicable to this permit modification application. The proposed modifications would not be contrary to the public interest; they would not adversely affect the public health, safety or welfare or the property of others. No adverse impacts are anticipated to occur as a result of the proposed modifications. The proposed modifications maintain the historic water elevation for Lake E and maintain historic flows for the project area. The modified system should also provide some improvement in water quality.

The Issue The ultimate issue is whether Celebrity Resorts, Inc., (Celebrity) is entitled to a Management and Storage of Surface Waters (MSSW) permit for a surface management system to serve its proposed development in Marion County, Florida.
Findings Of Fact PROPOSED PROJECT Celebrity is seeking a District MSSW permit to construct a surface water management system to serve a proposed recreation vehicle (RV) park. The facility is to be located in northern Marion County on the southern border of Orange Lake, an Outstanding Florida Water. The entire site is within the geographic boundaries of the District. The RV park is to be located on 75 acres of land, and is to contain 372 RV and "park model" sites, four bath houses, a clubhouse, and an expanded boathouse. There is a "break" in the watersheds of the Celebrity property caused by a ridge across the approximate center of the project site. The effect of this "break" is that approximately one-half of the property drains toward the lake while the approximate southerly half of the property drains into an independent depression creating a watershed separate from the lake. Parts of Marion County and Alachua county have been designated as Sensitive Karst Area Basin by the District. The project site is located in the designated area. The existing land use is open pasture. The property was previously used for citrus groves. STANDING Concerned Citizens of Orange Lake Area is an unincorporated group of approximately 76 individuals who want to prevent pollution of Orange Lake. Of the 76 members, three members were present and testified at the hearing. The members attending the hearing were an artist (Riley), a photographer (Suto), and a bass guide (Solomon). Ms. Suto testified that she lives about 1 to 1 1/2 miles from the site. Ms. Riley testified that she lives next door to Ms. Suto and determined that to be over two miles away from the site. Mr. Solomon testified that he lives on the southeast side of Orange Lake approximately 1 to 1 1/2 miles from the project site. No witness testified that any member has a property interest in the subject property. Of the members who testified, none use the subject property. There was no testimony that other members use the property. Twenty-six members wrote letters of concern to the District. Ms. Suto testified to the existence of high levels of lead in her well water. WATER QUANTITY The existing land use, pasture, was used to determine the pre- development peak rate and volume of discharge. The existing surface drainage of the 75-acre project site is divided into two basins. On the north side of the property, the surface water flows toward Orange Lake. This basin is designated on the plans, sheet 3 of 16, by a "2." The south portion of the property is contained within the landlocked drainage basin which is designated on the plans, sheet 3 of 16, by a "1." The post-development flow of surface water will be in the same direction as the pre-development flow. There are no proposed development plans or encroachments into the 100- year floodplain. Therefore, there is no increase in potential for damages to off-site property or persons caused by floodplain development or encroachment, retardance, acceleration, displacement, or diversion of surface waters. There is no reduction in natural storage areas and, in fact, the proposed project increases the natural storage on site. Drainage Basin 2 The District's criterion for systems discharging to basins with an outlet is that the post-development peak rate of discharge for the 25-year, 24- hour storm event shall not exceed the pre-development peak rate of discharge for the 25-year, 24-hour storm event. The District's criteria also require that the post-development volume of discharge not exceed the pre-development volume of discharge. The retention system which ultimately discharges to Orange Lake is designed to retain the entire 25-year, 24-hour storm event through the series of basins on site. The pre-development peak rate of discharge for the drainage basin which flows to the lake is 55 cubic feet per second (cfs) during the 25-year, 24-hour storm event. The post-development peak rate of discharge from drainage basin 2 is 4 cfs. The post-development peak rate of discharge is less than the pre- development peak rate of discharge. Runoff from each RV site will be collected in an individual, ten-inch- deep retention basin. Runoff from the road will be collected in roadside swales. Runoff from the clubhouse, country store, and associated parking lots will be conveyed to drainage retention area (DRA) No. 8. The individual retention basins have the capacity to retain the 25- year, 24-hour storm event without discharging. Any surface water discharges from the individual retention basins in Basins 2A, 2B, and 2C as designated on sheet 3 of 16 will flow to DRA Nos. 4, 5, and 7, respectively. In Basin 2D, runoff from the road and RV park model sites will flow to DRA No. 6. The discharge from DRA No. 6 in the 25-year, 24-hour storm will be zero (0) cfs. In larger storms, any discharge from DRA No. 6 will flow to DRA No. 7. In the event DRA No. 7 overflows, the runoff will flow to DRA No. 5. Basins 2G and 2F are located around two existing sinkholes which currently collect stormwater runoff. In the proposed project, Basins 2G and 2F continue to drain the same area as pre-development. However, additional impervious surfaces will be placed in the drainage area. For this reason, an additional three to five feet of clean fill will be placed in the bottom of each sinkhole for filtration purposes. Basins 2H and 2I are less than one acre and currently drain off site. Berms are proposed around the property line at the basin to keep the stormwater on site. Basins 2H and 2I retain 3/4 inch of runoff over the individual basin. The runoff from Basins 2E1 and 2E flows to DRA No. 8 via a drainage swale. DRA No. 8 will retain 3/4 inch of runoff from the drainage area and is an off-line retention basin. The DRA No. 8 is equipped with a diversion box which allows the 3/4 inch of runoff to enter the DRA and then diverts the runoff from larger storms around the DRA so that the treatment volume of runoff (3/4 inch) continues to be treated in DRA No. 8 and does not mix with and discharge from DRA No. 8 during larger storms. Drainage Basin 1 Drainage Basin 1 as designated on plan sheet 3 of 16 is a landlocked basin which does not discharge to Orange Lake. In Drainage Basin 1, as in Basin 2, the runoff from the RV sites flows to the individual retention basins which retain the 25-year, 96-hour storm event. The runoff from the road flows to swales. Overflow from the basins and swales flow to the DRAs. Drainage Basin 1 does not discharge during the 100- year, 24-hour or the 25-year, 24-hour storm event, pre-development or post- development Drainage Basin 1 is designed to retain the 100-year, 24-hour storm, which is an 11 inch storm event. Drainage Basin 1 is also designed to retain the 25-year, 96-hour storm event. The 25-year, 96-hour storm event is 143% of the 25-year, 24-hour storm event. WATER QUALITY Design Criteria The District's design criteria for water quality are set out in Section 40C-42.025, Florida Administrative Code. The District's retention criteria require that a proposed system have a treatment/pollution abatement volume of 1/2 inch of runoff from the site. For discharges to an OFW, the pollution abatement volume is increased by fifty percent. Therefore, the system must have the volume to retain 3/4 inch of runoff from the site. Each retention basin retains a minimum of 3/4 inch of runoff from the site. The District's criteria regarding quantity of water discharged require a larger volume of runoff to be retained than the District's criteria regarding quality. Therefore, the retention system exceeds the District's criteria regarding quality in order to meet the criteria regarding quantity. The District's retention criteria require that the basin recover the treatment volume within 72 hours. Most of the retention basins retain more than the required treatment volume of 3/4 inch, and most will also recover, or become dry, within 72 hours. The retention basins are capable of being effectively maintained in that the side slopes and bottom of the basins can easily accommodate mowing equipment. For erosion control, staked hay bales and silt screens will be utilized on site during construction to prevent the off-site transport of soil material. Following construction, the retention basins will be vegetated with sod to prevent erosion. The District's criteria require that facilities which receive stormwater runoff from areas with greater than fifty percent of impervious surface shall include a baffle or other device for preventing oil and grease from leaving the system. DRA Nos. 1, 4, 5, and 8 are equipped with an oil and grease removal device called a baffle. The baffle is an acceptable engineering design for the removal of oil and grease from stormwater in a retention basin. The facility operation is uncomplicated. If the individual basins did fill due to a storm event greater than the 25-year, 24-hour or the 25-year, 96- hour in the landlocked basin, they would simply overflow into a DRA. No structures are involved to prevent flooding in large storm events. Water Quality Impacts The individual retention basin at each RV site is considered off-line because it does not discharge in the 25-year, 24-hour storm event. DRA Nos. 1, 2, 3, 4, 5, 6, and 7 are considered off-line because they do not discharge during the design storm. DRA No. 8 is considered off-line because of the diversion box which provides for the retention of the treatment volume and diversion of the larger storms. Off-line retention systems generally show greater pollutant treatment efficiencies than other types of stormwater treatment. The first 1/2 inch of runoff or the "first flush" of rainfall contains ninety percent of the pollutants from the site. SURFACE WATER Utilizing information and methodologies generally accepted by experts in the field of water quality, the District analyzed and projected the average surface water and groundwater quality of the discharge from the surface water management system for the proposed project. No data on runoff concentrations currently exists for RV parks. This analysis was based on a review of existing data on untreated runoff concentrations from three multifamily developments and one highway study. Because data from studies of multifamily residential and highway projects was used, the District's estimates of the untreated runoff concentrations for this project are conservative in that the actual concentrations are probably less than estimated. The District's analysis of the average quality of the discharge from the proposed system was also based on projecting the treatment efficiencies associated with the system. This analysis was done by reviewing data from documented studies previously conducted to ascertain the treatment efficiency of retention methods of stormwater treatment. Generally, retention of the first 1/2 inch of runoff removes eighty percent of the pollutants. On this project, a treatment efficiency of ninety-five percent was assumed based on the fact that the system is off-line treatment and a minimum of 3/4 inch of runoff from the site will be retained in the basins prior to discharge. The expected average untreated runoff concentrations were then educed by the expected treatment efficiencies to project post-treatment water quality of the discharge from the proposed system. These numbers were then compared to Chapter 17-302, Florida Administrative Code, water quality standards for Class III water bodies, and ambient water quality in Orange Lake. Orange Lake is classified as an OFW. Therefore, the proposed project cannot be permitted if it will cause degradation of that water body. The background data or ambient water quality data for phosphorous and nitrogen was taken from the Orange Lake Biological Report by the Florida Game and Freshwater Fish Commission in 1986. The ambient water quality for the other parameters in Table 2 of District Exhibit 2 was computed using eight years of data from a District monitoring station on Orange Lake. The projected average concentration for each constituent in the discharge from the system is less than the ambient water quality of Orange Lake. Therefore, the proposed surface water discharge will not violate state water quality standards in waters of the state. The post-development pollutant loading rates should be equal to or better than the pollutant loading rates from the use of the property as citrus or pastureland because the runoff is being retained on site and treated before being discharged. GROUNDWATER Groundwater discharges were reviewed by assessing the type of soil below the retention basin and the distance to the water table. The soil on the site contains some organic matter which is beneficial for treatment purposes. Based on the borings submitted by Celebrity, the water table, if any, is five feet or more below the bottom of any proposed retention basin. Runoff in the basin will percolate through the soil. Nutrients such as nitrogen and phosphorus will be taken up by the vegetation in the bottom of the basins. Metals will bind to the soil material below the basin. Oils and greases will be broken down through microbial degradation into nontoxic material. Groundwater discharges from the proposed system will not violate any applicable state groundwater quality standards. These standards will be met within the first three feet below the treatment basins. The standards will also be met by the time the groundwater discharge moves to the edge of the zone of discharge which is at the property boundary. The discharge from the proposed Celebrity project will not cause or contribute to a violation of state water quality standards in the receiving waters. SINKHOLES Sinkholes may form on the site. Sinkholes that form will probably be "cover subsidence" sinkholes. Cover subsidence sinkholes are those in which a void below the surface fills with the soil from above, causing a depression in the ground surface. There are four relict sinkholes on site. They are cover subsidence sinkholes. The sinkhole nearest the lake has water in the bottom. Stormwater runoff is directed away from the sinkhole. Any water which enters the sinkhole from the land surface or above will enter from the sky. The District has proposed criteria for stormwater systems in designated Sensitive Karst Area Basins. Those criteria are that 1) the water in the basins shall be no deeper than ten feet deep; 2) there should be at least three feet of unconsolidated material between the bottom of the basin and the top of the water table; and 3) the basins should be fully vegetated. The District currently applies these criteria as policy. In this project, the basins are shallow, ranging from ten inches deep at the RV sites to 2 1/2 feet in the DRAs. The basins have at least three feet of unconsolidated material between the bottom of the basin and the top of the water table. In the soil borings performed by Celebrity, the water table was shown to exist between five and fifty feet below land surface. The proposed project design meets or exceeds the proposed criteria for Sensitive Karst Area Basins. The basins will be fully vegetated or sodded with grass. Lineations or lineaments are solution features which may indicate a fracture of the underlying limestone. There may be a lineament on the site. There are other sinkholes in the area. If a cover subsidence sinkhole develops in an individual retention basin or DRA, stormwater, if any, will seep or percolate through the several feet of soil prior to reaching an aquifer. Most of the pollutants in the retention basin will meet groundwater quality standards prior to percolation and further treatment in the soil. OPERATION AND MAINTENANCE Special conditions Nos. 13, 14, and 15 on the permit will require Celebrity to inspect the system monthly for sinkhole development. If a sinkhole develops, Celebrity must notify the District within 48 hours of its discovery. Celebrity must submit a detailed repair plan within 30 days for written approval by the District. Celebrity proposes to repair any sinkholes that develop by a District- approved method. Celebrity Resorts, Inc., is a legally established corporation registered in Delaware and owns the subject property. Celebrity does not intend to subdivide the property but to sell memberships to use the property on a time-share basis. Celebrity will administratively operate the site by employing a park manager who will remain on the property 24 hours a day. If any problems occur with the basins, either he or his designee will be on site to respond quickly to the situation. The park manager will have a full-time maintenance staff which will operate the park. Celebrity will financially operate and maintain the proposed system using funds currently raised and in the future by membership fees. Celebrity is a publicly held corporation. Funds raised from the sale of stock, approximately $3,500,000, have paid for legal and administrative fees as well as the land purchase. Approximately $400,000 has been reserved to operate the facility. It will cost approximately $15,000 per month to run the park. Memberships will be sold for $300 per year. Part of the membership fees will go toward the general maintenance of the site. Maintenance of the proposed system will include regular mowing and monthly inspection for sinkholes and repair if necessary. WETLANDS IMPACTS OF THE PROJECT The property contains waters of the state wetlands and isolated wetlands. The waters of the state wetlands are those along the shore of Orange Lake. One isolated wetland exists on site in the sinkhole which is closest to the lake. The sinkhole has standing water in which lemna, or duckweed, is growing. Duckweed is a listed plant species in Section 16.1.1(2) of the Handbook. No construction is proposed in either the waters of the state wetlands or the isolated wetland. The District criteria require the review of impacts to off-site aquatic and wetland dependent species relative to the functions currently provided by the wetlands to these types of fish and wildlife. Since there will be no construction in the wetlands, there will be no impacts to the habitat, abundance and diversity, or food sources of off-site aquatic and wetland dependent species from this proposed project. No threatened or endangered aquatic and wetland dependent species were observed on site. The proposed permit application will not adversely affect natural resources, fish, or wildlife in a manner which is inconsistent with the District criteria. The proposed permit application will not adversely affect hydrologically-related environmental functions in a manner which is inconsistent with the District criteria.

Findings Of Fact The Parties and the Property. The Respondent, Saddlebrook Resorts, Inc. (Saddlebrook), is a corporation organized and existing under the laws of Florida, and is wholly owned by the Dempsey family. Saddlebrook is located on approximately 480 acres in central Pasco County, east of I-75 and south of State Road 54. The Petitioner, Wiregrass Ranch, Inc. (Wiregrass) is a corporation organized and existing under the laws of Florida, and is wholly owned by the Porter family ("the Porters"). Wiregrass owns approximately 5,000 acres of property which extends from Saddlebrook west approximately one mile to State Road 581 and south for approximately four miles. The Respondent, the Southwest Florida Water Management District (SWFWMD), is a political subdivision created pursuant to Chapter 61-691, Laws of Florida, which exists and operates under the Water Resources Act, Fla. Stat., Ch. 373. SWFWMD is charged with regulating, among other things, surface water management systems in Pasco County. Saddlebrook discharges surface water onto Wiregrass at two locations on the southern and western boundaries of Saddlebrook, known as the south outfall and the west outfall. Saddlebrook's property is part of a drainage basin totalling approximately 1400 acres that contributes runoff to Wiregrass' property. Until approximately 1973, the Saddlebrook property was undeveloped and owned by the Porters. In approximately 1973, the Porters sold the Saddlebrook property to the Refram family, which began developing the property. In approximately 1979, Saddlebrook acquired the property from the Reframs. The Saddlebrook property includes residential development, a conference center, and golf course and tennis facilities. Wiregrass' property, which is largely undeveloped and used for ranching, consists of pine-palmetto flatwoods, wetland strands, isolated wetlands, and improved pastures. The Porters' Civil Action Against Saddlebrook. The Porters instituted a civil action against Saddlebrook, Porter, et al. v. Saddlebrook Resorts, Inc., Case No. CA 83-1860, in the Circuit Court of the Sixth Judicial District, Pasco County, complaining that post-development discharges from Saddlebrook exceed pre-development discharges. In the civil litigation, the Porters contended that Saddlebrook's peak flow discharges should be returned to pre-development, or 1973, levels. A primary purpose of Saddlebrook's proposed redesign is to return peak flow discharges to those levels that existed in 1973, in response to the Porters' complaints in the civil action. Saddlebrook's current surface water management system is deemed by SWFWMD to be in compliance with Rule 40D-4, and SWFWMD's regulations do not require redesign or modification of the current system. Prior to Saddlebrook's submission of its application, SWFWMD advised Saddlebrook that, because Rule 40D-4 became effective on October 1, 1984, SWFWMD considered that date to be the "pre-development" condition for purposes of evaluating Saddlebrook's discharges. Saddlebrook requested that SWFWMD evaluate its application using 1973 as the pre-development condition. SWFWMD advised Saddlebrook that it would apply 1973 as the pre-development condition if the Porters consented. By letter from the Porters' counsel to SWFWMD dated January 31, 1990, the Porters provided their express consent to SWFWMD's use of 1973 as the pre- development date for purposes of evaluating those discharges relevant to Saddlebrook's MSSW permit application. Saddlebrook's MSSW Permit Application. On or about February 8, 1990, Saddlebrook submitted its application for MSSW permit no. 497318.00, seeking SWFWMD's conceptual approval of the redesign of Saddlebrook's surface water management system. The proposed redesign calls for modification of most of the existing drainage control structures at Saddlebrook and installation of new control structures at several locations, including the south and west outfalls. After submission of its initial application, Saddlebrook made various subsequent submittals in response to SWFWMD requests for additional information. Saddlebrook's response to SWFWMD's requests culminated in final submittals on March 7, 1991 and April 5, 1991. In its various submittals, Saddlebrook provided, among other things, detailed descriptions of all proposed modifications to its drainage system, engineering reports, and computerized flood-routing analyses of runoff from Saddlebrook under pre-development (1973) and post-modification conditions. Saddlebrook provided all information requested, and SWFWMD thereafter deemed its application complete. SWFWMD's Review of Saddlebrook's Application. In the fifteen months following Saddlwbrook's initial February, 1990, submittal, SWFWMD conducted an intensive review of the application. During the course of this review, SWFWMD staff performed numerous field inspections, made an independent determination of all input data to the computer analyses of Saddlebrook's discharges, and made six separate formal requests for additional information. SWFWMD's requests for additional information required, among other things, that Saddlebrook modify various input data and rerun its computer analyses of discharges under the pre-development and post-modification conditions. In addition, SWFWMD required Saddlebrook to perform computer modelling analyses of discharges from Wiregrass' property onto the property of downstream landowners. Because, unlike the Porters, these downstream owners had not provided consent to use 1973 as the relevant pre-development date, SWFWMD required Saddlebrook to model this downstream discharge using a "pre- development" date of 1984. SWFWMD performed its standard review procedures in connection with Saddlebrooks' application. In addition, SWFWMD also performed its own computer-modelling analyses of Saddlebrook's discharges. This modelling was based on input data independently collected by SWFWMD staff in the field and from other sources. SWFWMD staff also met with the Porters' hydrologist, Dr. Gerald Seaburn, and thoroughly reviewed concerns he expressed in connection with Saddlebrook's application. In addressing these concerns, SWFWMD performed additional work, including conferring with an independent soils expert, performing additional field inspections, and modifying the SWFWMD computer modelling analyses based on alternative input parameters suggested by Dr. Seaburn. In reviewing Saddlebrook's application, SWFWMD applied the design and performance criteria set forth in its "Basis of Review for Surface Water Management Permit Applications" ("Basis of Review"), which is incorporated by reference in F.A.C. Rule Chapter 40D-4. Based upon its review of Saddlebrook's application, SWFWMD concluded that Saddlebrook had demonstrated compliance with the design and performance criteria set forth in SWFWMD's Basis of Review and the conditions for permit issuance under F.A.C. Rule 40D-4.301. By a Staff Report dated April 29, 1991, and Notice of Proposed Agency Action dated May 3, 1991, SWFWMD recommended approval of Saddlebrook's application. Compliance With SWFWMD Permitting Criteria. The design and performance criteria for MSSW permitting set forth in SWFWMD's Basis of Review fall into four categories: (1) water quantity, in terms of peak flow discharges for projects, like Saddlebrook's, located in open drainage basins; (2) flood protection; (3) water quality; and (4) wetlands impacts. Water Quantity. Under the Basis of Review's water quantity standards, SWFWMD requires that projected peak flow discharges during a 25-year, 24-hour storm event under the proposed system be reasonably similar to peak flow discharges under the pre- development condition. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's water-quantity standards. This evidence demonstrated that peak flow discharges during a 25-year, 24-hour storm event under the proposed system will be less than, but reasonably similar to, pre-development (1973) peak flow discharges. The evidence presented at the formal hearing also demonstrated that, under the proposed system, peak flow discharges during a 25-year, 24-hour storm event from Wiregrass' property onto downstream landowners will be less than, but reasonably similar to, 1984 peak flow discharges. The evidence presented by Saddlebrook further demonstrated that storage will be increased under the proposed redesign versus the pre- development, 1973 condition. On Saddlebrook's property, there will be approximately 35 percent more storage than existed in 1973, and the total storage for Saddlebrook and the contributing drainage basin upstream of Saddlebrook will be increased by approximately 15 percent over that existing in 1973. Flood Protection. Under the flood-protection standards of the Basis of Review, SWFWMD requires that the applicant demonstrate that under the proposed condition the lower floor of all residential and other buildings on-site, and in areas affected by the site, will be above the 100-year flood elevation. SWFWMD also requires that there be no net encroachment into the flood plain, up to that encompassed by the 100-year event, which will adversely affect conveyance, storage, water quality or adjacent lands. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's flood-protection standards. The testimony of Mr. Fuxan and Wiregrass' related exhibit, Ranch Ex. 35, purporting to show that in a 25-year, 24-hour storm Saddlebrook's proposed redesign will "flood the [Saddlebrook perimeter] roads and just sheet flow onto the Porter property" is not accurate. As part of its redesign, Saddlebrook will construct an additional berm along the southwestern and southern perimeters of its property. This berm will detain water on Saddlebrook's property during a 25-year, 24-hour storm event and prevent it from "sheet-flowing" onto the Wiregrass property. Water Quality. Under the water-quality standards of the Basis of Review, SWFWMD requires, for systems like Saddlebrook's involving wet detention and isolated wetlands, that the applicant provide sufficient storage to treat one inch of runoff from the basins contributing runoff to the site. This volume must be discharged in no less than 120 hours, with no more than one-half of the volume being discharged within the first 60 hours. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's water-quality standards. Wetland Impacts. Under the wetland-impacts standards of the Basis of Review, SWFWMD requires that the applicant provide reasonable assurance that the proposed system will not adversely impact on-site and downstream wetlands. The evidence presented at the formal hearing demonstrated that Saddlebrook has provided reasonable assurance that the proposed redesign will cause no adverse impacts to on-site wetlands. Saddlebrook's proposed redesign will impact only approximately .167 acres of on-site wetlands, for which Saddlebrook will fully mitigate by creating .174 acres of forested wetlands and buffer area. The evidence presented at the formal hearing also demonstrated that Saddlebrook has provided reasonable assurance that the proposed redesign will cause no adverse impacts to off-site wetlands. Reasonable assurance that off- site wetlands will not be adversely impacted was demonstrated by, among other things, evidence establishing that: (1) discharge points will not change under the proposed condition; (2) discharge elevations will be reasonably similar under the proposed condition; (3) there will be no significant variation in the water fluctuations in the wetlands adjacent to the south and west outfalls as a result of the proposed condition; (4) the drainage basin areas will be reasonably similar under the proposed condition; and (5) the proposed redesign will satisfy SWFWMD's water quality requirements. Wiregrass' Petition. In its Petition for Formal Administrative Hearing, Wiregrass focused primarily on water quality issues and stormwater runoff rates (or peak flow discharges), alleging the following "ultimate facts" which it claimed "entitle [it] to relief": The application, as submitted, contains insufficient storage to meet water quality criteria. The application, as submitted, will result in storage volumes on the project site which will not be recovered within 72 hours [sic] as required by the DISTRICT criteria. The application, as submitted, contains calculations based on erroneous hydraulic gradients. The application, as submitted, will result in storage volumes insufficient to meet water quality criteria as required by DISTRICT criteria. Post development stormwater runoff rates are underestimated in the application, resulting in system design with insufficient retention storage capacity to meet the DISTRICT's water quantity criteria. The failure to store stormwater or irrigation runoff impacts the substantial interest of the RANCH in that it deprives it of groundwater resources necessary for the successful operation of the ranch. Further, the lack of storage of stormwater and irrigation water is a prohibited waste of the water resources. At the formal hearing, Wiregrass presented no evidence to support any of the foregoing allegations of its Petition. Objections Raised by Wiregrass At The Hearing. At the final hearing, Wiregrass' opposition to Saddlebrook's permit application focused on three different grounds: For purposes of evaluating peak flow discharges, SWFWMD does not have jurisdiction to use a pre-development date prior to October 1, 1984. Under F.A.C. Rule 40D-4.301(1)(i), which provides that an applicant must give reasonable assurance that the surface water management systems "is consistent with the requirements of other public agencies," SWFWMD must apply not only its own permitting criteria but also those of other governmental entities, including county planning ordinan Under F.A.C. Rule 40D-4.301(1)(b), which provides that a permit application must give reasonable assurances that the surface water management system "will not cause adverse water . . . quantity impacts", SWFWMD must consider whether the annual volume of runoff will increase as a result of the proposed surface water management system. None of the foregoing objections was raised in Wiregrass' Petition as a basis for denying Saddlebrook's application. (Annual volume was alluded to in the Petition only as being pertinent to the question of Wiregrass' "substantial interest" for purposes of standing.) In any event, for the reasons set forth below, each of these objections was refuted by the evidence presented at the formal hearing. The 1973 Pre-Development Date. In their civil action against Saddlebrook, the Porters took the position that Saddlebrook's surface water management system should be redesigned so that discharges approximate those levels existing in 1973, before development of the Saddlebrook property. Dr. Gerald Seaburn, a hydrologist retained by the Porters, testified in the civil action that 1973 is the appropriate pre-development date for purposes of evaluating Saddlebrook's peak flow discharges. David Fuxan, a civil engineer retained by the Porters, took the position in the civil action that Saddlebrook should modify its surface water management system so as to return peak flow discharges to 1973 levels. At the formal hearing in this proceeding, Mr. Fuxan testified that it is still his position that Saddlebrook should modify its surface water management system so as to return peak flow discharges to 1973 levels. By letter from the Porters' counsel to SWFWMD dated January 31, 1990, the Porters provided their express consent to SWFWMD's use of 1973 as the pre- development date for evaluating those discharges relevant to Saddlebrook's MSSW permit application. Use of a 1984 "pre-development" date would prevent Saddlebrook from making the modifications the Porters claim in the civil litigation that it must make. Saddlebrook's existing system, about which the Porters complain in the civil litigation, is in all material respects the same system that was in place on October 1, 1984. Use of this existing system as the benchmark of comparison for attenuation of peak flows, therefore, would mean that substantial modifications to the existing system could not be made without substantially increasing retention storage on Saddlebrook. Substantially increasing retention storage on Saddlebrook is not possible due to the high water table and proximity of the lower aquifer. See Finding of Fact 70, below. In addition, a primary claim of the Porters in the civil action is that duration of flow under Saddlebrook's existing system exceeds 1973 levels and has resulted in expanded wetlands on the Porter property. But duration of flow and peak flow discharges are inversely related: duration of flow can be decreased only if peak flow discharges are increased. Accordingly, the only way that Saddlebrook can reduce the duration of flow onto Wiregrass to 1973 levels, as the Porters have demanded, other than increasing retention storage on Saddlebrook, is to return peak flow discharges to 1973 levels. Other Governmental Agencies' Requirements. F.A.C. Rule 40D-4.301(1)(i) provides that a permit applicant must give reasonable assurance that the surface water management system "is consistent with the requirements of other public agencies." SWFWMD has consistently interpreted this provision to be "advisory", i.e., to apprise applicants that they must also comply with other applicable laws and that issuance of an MSSW permit by the District does not relieve them of the responsibility to obtain all necessary local and other permits. SWFWMD's long-standing and consistently-applied interpretation and practice is not to require applicants to prove compliance with the regulations of other govermental agencies in order to obtain an MSSW permit. There are two primary reasons for this interpretation and practice. First, the Southwest Florida Water Management District includes 16 counties and 96 municipalities. In addition, other state and various federal agencies have jurisdiction within its territory. It is impracticable for SWFWMD to become familiar with, and to apply, the permitting and other regulations of more than 100 other agencies. Second, SWFWMD has concluded that, under Part 4 of Secton 373 of the Flordia Statutes, it does not have authority to deny a permit application based on its interpretation of another governmental agency's regulations. In any event, the evidence demonstrates that Saddlebrook has provided reasonable assurance that the proposed redesign will be "consistent with the requirements of other public agencies" as provided in F.A.C. Rule 40D- 4.301(1)(i). Limiting Condition No. 3 of the proposed permit requires that Saddlebrook must comply with Pasco County and other local requirements: The Permittee shall comply with all applicable local subdivision regulations and other local requirements. In addition the permittee shall obtain all necessary Federal, State, local and special district authorizations prior to the start of any construction or alteration of works authorized by this permit. In addition, Standard Condition No.3 ensures that SWFWMD approval will not supersede any separate permitting or other requirements imposed by Pasco County: The issuance of this permit does not . . . authorize any . . . infringement of federal, state or local laws or regulations. (Emphasis added.) Finally, the Pasco County ordinance upon which Wiregrass relies imposes requirements that are in substance identical to SWFWMD's with respect to MSSW permit applications. Saddlebrook's compliance with SWFWMD's regulations likewise would satisfy the substance of the requirements of the county ordinance. Annual Volume of Runoff. F.A.C. Rule 40D-4 (incorporating the Basis of Review) does not address, and SWFWMD does not regulate, the annual volume of runoff in open drainage basins. If annual volume of runoff is relevant under Rule 40D-4.301, as Wiregrass contends, that rule requires only that the applicant provide reasonable assurance that "the surface water management system" will not cause adverse quantity impacts. Saddlebrook's existing surface water management system has not caused a significant increase in the annual volume of runoff onto Wiregrass' property. The increase in the annual volume of runoff from Saddlebrook that has occurred over the pre-development 1973 condition has resulted from the urbanization of Saddlebrook's property. The increase in the annual volume of runoff from Saddlebrook over that existing prior to development (1973) is approximately 3.4 inches. This increase is only a small fraction of the natural year-to-year variation in runoff resulting from differences in rainfall alone. Rainfall can vary up to 30 inches on an annual basis, from 40 to 70 inches per year. The resulting year-to-year variations in runoff can total as much as 20 inches. The approximately 3.4 inches increase in the annual volume of runoff from Saddlebrook due to urbanization has caused no adverse impact to Wiregrass. The natural drainage system on the Wiregrass property has in the past and throughout its history received and handled increases in the annual volume of runoff of up to 20 inches due to rainfall differences. Such increases simply flow through Wiregrass' property. Of the approximately 3.4 inch increase in annual runoff due to urbanization, only approximately one-third of an inch is due to the filling in of bayheads by Saddlebrook's prior owner. This increase is insignificant and has not caused a substantial adverse impact to Wiregrass. Any reduction of storage resulting from the filling of bayheads will be more than compensated for under the proposed redesign. Storage on Saddlebrook's property will be increased by approximately 35 percent under the proposed condition over that existing in 1973, before the bayheads were filled. In open drainage basins, like Saddlebrook's, downstream flooding is a function of the rate of peak flow of discharge, not the annual volume of runoff. This is one of the reasons why, in the case of open drainage basins, SWFWMD regulates peak flow discharges and not the annual volume of runoff. Because Saddlebrook's proposed redesign will attenuate peak flow discharges to those levels that existed in the pre-devlopment 1973 condition, Saddlebrook has provided reasonable assurance that there will not be increased flooding on Wiregrass' property in the future. The evidence does not establish that Wiregrass has suffered, or will suffer, any adverse impact due to an increase in the annual volume of runoff from Saddlebrook as a result of the design, or redesign, of the system, or as a result of urbanization, or otherwise. It is not possible to design a surface water management system at Saddlebrook that would reduce the annual volume of runoff. Such a system, which involves the percolation of surface water from retention ponds into a deeper, aquifer system, requires a deep water table. At Saddlebrook, the water table is near the ground surface. As a result, it is not possible to store a significant quantity of water in retention ponds between storm events. In addition, the water levels in the deeper and the shallower aquifer systems at Saddlebrook are approximately the same and, therefore, there is insufficient hydraulic pressure to push the water through the confining layer between the two systems and into the deeper aquifer system.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Southwest Florida Water Management District enter a final order granting Saddlebrook's application for surface water management permit no. 497318.00, subject to the terms and conditions in the SWFWMD Staff Report. RECOMMENDED this 31st day of March, 1992, in Tallahassee, Florida. J. LAWRENCE JOHNSTON 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 31st day of March, 1992. APPENDIX TO RECOMMENDED ORDER, CASE NO. 91-3658 To comply with the requirements of Section 120.59(2), Fla. Stat. (1991), the following rulings are made on the parties' proposed findings of fact: Petitioner's Proposed Findings of Fact. 1.-4. Accepted and incorporated. Rejected as not proven and contrary to the greater weight of the evidence. Accepted and incorporated to the extent not subordinate or unnecessary. 7.-9. Rejected as not proven and contrary to the greater weight of the evidence. First sentence, accepted. Second sentence, rejected as not proven and contrary to the greater weight of the evidence. Accepted but not necessary. 12.-13. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but not necessary. The extent of the wetland expansion is rejected as not proven and contrary to the greater weight of the evidence. The rest is accepted. However, the increased volume is due in large part to urbanization, not to the surface water management system. It also is due in part to alterations to the property done by the Porters. Accepted but subordinate and unnecessary. Accepted. However, this would occur only during a 25-year, 24-hour storm event, and there was no evidence that one has occurred or, if it has, whether Mr. Porter was there to observe it. 18.-20. Accepted but subordinate and unnecessary. Characterization "much of" is rejected as not proven and contrary to the greater weight of the evidence. Otherwise, accepted but subordinate and unnecessary. Accepted and incorporated. Rejected as not proven and contrary to the greater weight of the evidence. Rejected as not proven and contrary to the greater weight of the evidence. Rejected as not proven and contrary to the greater weight of the evidence that lichen lines, by themselves, are ordinarily are sufficient to set jurisdictional lines. 26.-29. Rejected as not proven and contrary to the greater weight of the evidence. Even if it were proven that the wetlands had expanded, it was not proven, and is contrary to the greater weight of the evidence, that Saddlebrook (and, especially, Saddlebrook's surface water management system) caused the expansion. First sentence, accepted but cumulative. The rest is rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. In any event, both factors are undeniably significant. 32.-34. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. 39.-41. Rejected as not proven and contrary to the greater weight of the evidence that SWFWMD does not apply it. The evidence was that SWFWMD interprets it differently than Wiregrass proposes and applies its own interpretation. Under the SWFWMD interpretation, the permit conditions requiring compliance with other legal requirements constitute the necessary "reasonable assurance." In addition, SWFWMD's review and evaluation is not complete until this formal administrative proceeding is completed, and the Pasco County ordinance has been considered as part of this proceeding. Rejected as not proven and contrary to the greater weight of the evidence. Again, SWFWMD's review and evaluation is not complete until this formal administrative proceeding is completed, and annual volume has been considered as part of this proceeding. That consideration has affirmed SWFWMD's position that, at least in this case, the proposed stormwater management system does not cause an increase in annual volume that would result in denial of the application. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. First sentence, accepted (although the characterization "far exceed" is imprecise) and incorporated. Second sentence, rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary that no "stipulation" was entered into. But the evidence is clear that Wiregrass, Saddlebrook and SWFWMD all agreed to the use of 1973 as the point of comparison for peak flow discharges. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Respondents' Proposed Findings of Fact. The proposed findings of fact contained in the Proposed Recommended Order of Respondents Saddlebrook Resorts, Inc., and Southwest Florida Water Management District are accepted and incorporated to the extent not subordinate or unnecessary.

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 in this case is whether the Southwest Florida Water Management District (the District) should grant the application of the Misty Creek Country Club, Inc. (the Club), to modify MSSW Permit No. 400037.
Findings Of Fact Background Petitioners are owners of property adjacent to Lake No. 7 of the Misty Creek Country Club in a development called The Preserves at Misty Creek-- specifically, lot 113 (Robert and Lee Werner), lot 114 (Charles and Rosemary Biondolillo), lots 115 and 115A (Ignatius and Judith Bertola), lots 117 and 117A (Don and Halina Bogdanske), lots 118 and 118A (Louis and Betty Mitchell), lots 119 and 119A (George and Dorothy Holly), lots 120 and 120A (John and Maureen Higgins), and lot 121 (William and June Spence). Respondent, the Misty Creek Country Club (the Club), operates a golf course and country club located at The Preserves at Misty Creek under a 99-year lease with Gator Creek Lands, the developer of The Preserves at Misty Creek. Existing System Design and Application for Permit Modification In 1985, Respondent Southwest Florida Water Management District, issued a surface water management permit for development of a 730-acre residential development and golf course. The District subsequently issued to the Club operation phase authorization for the surface water management system associated with the golf course portion of the development in March of 1992. Under the original permit, Lake No. 7 was part of the overall stormwater management system for the golf course. The lake is approximately seven and half to eight acres in size and is part of a total drainage basin of approximately twenty-eight acres. As originally designed, Lake No. 7 is a detention with filtration system. An underdrain in the side of the bank provides water quality treatment, filtering out oils and greases, fertilizers and other contaminants. A control elevation of 31.02 was established for Lake No. 7 through construction of a weir. Between elevation 31.00 and 31.02, water discharges through the underdrain system providing water quality treatment. Above elevation 31.02, water flows over the control structure into Lake No. 6, and ultimately discharges to Cow Pen Slough, which is Class III waters of the state. The Club presently has a water use permit from the District which allows withdrawal of groundwater for irrigation of the golf course. Groundwater is stored in Lake No. 7 prior to use for irrigation when needed to augment water in the lake. Special Condition Number 2 of the water use permit required the Club to investigate the feasibility of using reclaimed or reuse water in lieu of groundwater for irrigation purposes at the golf course. As a result of the investigation required by Special Condition Number 2 of the water use permit, the Club filed an application with the District to modify its surface water management permit to allow for the introduction of reuse water into Lake No. 7. Under that application, there would have been no significant modifications to the stormwater management system. Reuse water would have replaced groundwater as a source for augmenting water in the lake when needed for irrigation. An eight-inch service line would convey the reuse water to Lake 7, and a float valve would control the introduction of reuse water into Lake No. 7. When water levels in the lake fell below elevation 30.5', the float valve would open the effluent line to allow introduction of reuse water into the lake; when the water elevation in the lake reached 31.0', the float valve would shut off the flow of water. There would be gate valves on either side of the structure that could be manually closed, if necessary, to stop the flow of reuse water into the lake if the float valve malfunctioned. Club personnel would have access to the gate valves and could manually stop the flow of reuse water into the lake if necessary. On August 9, 1995, just days prior to the final hearing in this matter, the Club proposed to modify its application to make certain structural changes in the design of the surface water management system. Specifically, the Club proposed to plug the window in the weir, raise the elevation of the weir or control structure to elevation 33.6, raise the elevation of the berm along the north end of Lake No. 7 adjacent to the weir to elevation 33.6, and plug the underdrain. The purpose of the proposed modifications to the design of the system was to assure that no discharge from Lake No. 7 would occur up to and including the 100-year storm event. A 100-year storm event is equal to 10 inches of rainfall in a 24-hour period. Source and Quality of Reuse Water The Club also entered into an agreement with Sarasota County to accept reuse water from the county's new Bee Ridge wastewater treatment facility. That agreement specifies the terms under which the Club will accept reuse water from the County. The County's Bee Ridge facility is presently under construction and is not yet operating. As permitted by the Department of Environmental Protection, the Bee Ridge wastewater treatment facility will use a Bardenpho waste treatment system which is a licensed process to provide advanced waste treatment. The construction permit establishes effluent limits for the facility that are comparable to a level of treatment known as advanced secondary treatment, but the County Commission for Sarasota County has instructed the County staff to operate the Bee Ridge facility as an advanced waste treatment plant. Advanced waste treatment is defined by the quality of the effluent produced. For advanced waste treatment, the effluent may not exceed 5 milligrams/Liter of biochemical oxygen demand (BOD) or total suspended solids (TSS), 3 milligrams/Liter of total nitrogen, or 1 milligram/Liter of total phosphorus. It also requires high level disinfection. Advanced secondary treatment requires the same level of treatment for TSS but the limit for nitrates is 10 milligrams/Liter. High level disinfection is also required for advanced secondary treatment. In Florida, reuse systems require a minimum of advanced secondary treatment. High level disinfection is the level of treatment that generally is accepted as being a reasonable level of treatment. The Bee Ridge permit issued to Sarasota County identifies the Club as one of the recipients of reuse water for irrigation. Condition Number 21 of that permit provides that the use of golf course ponds to store reuse water is not authorized under the County's permit until issuance of a separate permit or modification of the County's permit. Although the District did not require Misty Creek to submit any information about the modification of the County's permit, there was no basis for assuming that the County permit could not be modified. To the contrary, the permit provides that authorization may be obtained by permit modification. Under the late modification to the Club's application, the reuse water transmission line and float valve system, with backup manual gate valve system, is unchanged. So are the water elevations at which the float valve system will automatically introduce reuse water into Lake 7 and shut off. Sarasota County already has constructed the water transmission system that would deliver reuse water to the Club. At the request of the District, the Club provided copies of the drawings of the float valve structure as permitted by the Department of Environmental Protection. The District did not require certified drawings of that structure. But the District will require the Club to provide as-built drawings following completion of construction prior to the introduction of reuse water into Lake No. 7. Property Ownership Each of the Petitioners owns a residential lot adjacent to Lake No. 7. At the time of the Petitioners' purchase of the individual residential lots, the Club leased certain property immediately west of Lake No. 7 from the developer of The Preserve at Misty Creek. The leased premises included a piece of land extending into the lake known as the 19th green. As a result of negotiations between the Club and the developer, it was determined that the 19th green would be removed and the land between the approximate top of bank of Lake No. 7 and the private residential lots would be released from the Club's lease. The developer subsequently conveyed the property that had been released from the Club's lease to the individual lot owners (the "A" parcels listed in Finding 1). At the time of the conveyance of the additional parcels, the attorney for the developer prepared deeds for each individual parcel with a metes and bounds description off the rear of the residential lots to which they were being added. While the Club's application for modification of its surface water management permit was being processed by the District, counsel for Petitioners provided the District with copies of the individual deeds and questioned whether the Club had ownership or control of the land which was the subject of the application sufficient to meet the District's permitting requirements. In response to a request for information regarding the ownership of the property that was the subject of the application, the Club submitted to the District a topographical survey prepared by Mr. Steven Burkholder, a registered professional land surveyor with AM Engineering. The topographical survey depicted: the elevation of the water in the Lake No. 7 on the day that the survey was conducted, labeled "approximate water's edge"; the elevation of the "top of bank"; and the easternmost line of private ownership by Petitioners. Mr. Burkholder determined the line of private property ownership by reproducing a boundary survey attached to the individual deeds conveying the additional parcels to the Petitioners. He testified that he was confident that the topographical survey he prepared accurately represented the most easterly boundary of the Petitioners' ownership. The elevation of the line of private ownership as depicted on the survey prepared by Mr. Burkholder ranges from a low of approximately 34.5 to 35.2. The elevation of the line labeled "top of bank" ranges from a high of 35.6 to a low of 34.4. The elevation of the water in Lake No. 7 would be controlled by the elevation of the modified control structure which is proposed to be set at elevation 33.6. After modification of the surface water management system to retain the 100-year storm event, at no time would water levels in the lake rise above the existing elevation of the "top of bank." The Petitioners testified that they believed that they owned to the water's edge or edge of the lake, but Mr. Burkholder testified that a property boundary could not be determined based on an elevation depicting the water's edge because that line would change as the level of the water rose and fell. The Petitioners also presented evidence that the developer's attorney made representations to them that their ownership extended to the "approximate high water line." But there appears to be no such thing as an "approximate high water line" in surveying terms. Where the boundary of a lake is depicted on a survey it generally is depicted from top of bank to top of bank. In any event, the legal descriptions of the parcels conveyed to the Petitioners were not based on a reference to either a water line or the water's edge or the lake at all. Instead, the legal descriptions were based solely on a metes and bounds description off the rear of the residential lots. Notwithstanding some contrary evidence, if the Petitioners owned to the water's edge, such ownership would require the Petitioners to consent to or join in the amended application for the modification of the Club's surface water management permit. Information regarding the ownership or control and the legal availability of the receiving water system is required as part of the contents of an application under Rule 40D-4.101(2)(d)6. and 7., Florida Administrative Code. The amended application requires the ability to "spread" Lake 7 in the direction of the Petitioners' property. If the Petitioners own the property on which the Club intends to "spread" Lake 7 in order to make the amended application work, the Petitioners must consent or join. The issue of the legal ownership and control of the Petitioners and the Club currently is in litigation in state circuit court. If the state circuit court determines that the easterly boundary of the "A" parcels lies to the east of the "top of bank," consideration would have to be given to modifying any permit issued to the Club to insure that the designed "spread" of Lake 7 in a storm event up to and including a 100-year storm event does not encroach on the Petitioners' property. District Permit Requirements The District has never before processed an application for a surface water management permit allowing commingling of storm water and reuse water. The District applied Chapter 40D-4, Florida Administrative Code, in reviewing the Club's permit application. There are no specific provisions in Rule 40D-4 or the District's Basis of Review for Surface Water Management Permit Applications that address the commingling of stormwater and reuse water; on the other hand, no rules of the District prohibit the introduction of other types of water into a stormwater treatment pond so long as the requirements of Rule 40D-4 are met. The District has the authority to allow stormwater and reuse water to be commingled. Section 40D-4.301, Florida Administrative Code, contains the conditions for issuance of a surface water management permit. Permitting Criteria In order to obtain a surface water management permit to commingle stormwater and reuse water in Lake 7, the Club must provide reasonable assurances that the proposed modifications to its existing system will provide adequate flood control and drainage; not cause adverse water quality and quantity impacts on receiving waters and adjacent lands; not result in a violation of surface water quality standards; not cause adverse impacts on surface and groundwater levels and flows; not diminish the capability of the lake to fluctuate through the full range established for it in Chapter 40D-8, Florida Administrative Code; not cause adverse environmental impacts to wetlands, fish and wildlife or other natural resources; be effectively operated and maintained; not adversely affect public health and safety; be consistent with other public agency's requirements; not otherwise be harmful to water resources of the District; and not be against public policy. No surface or groundwater levels or flows have been set for this area of the District, so that permit criterion is not applicable to the Club's application. The Club's application will not impact wetlands or fish and wildlife associated with wetlands as described in F.A.C. Rule 40D-4.301(1)(f). There are no wetlands regulated by the District in the project site. The Club has submitted to the District an operation and maintenance plan for the modified surface water management system. The operation and maintenance plan is in compliance with the District's permitting criteria contained in Rule 40D-4.301(1)(g). The District's regulation with respect to the requirement that a project not adversely affect the public health and safety is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The permitting criterion that a project must be consistent with the requirements of other public agencies was met by inclusion in the permit of Special Conditions Nos. 5 and 6, Limiting Condition No. 3 and Standard Condition No. 3, which require that the surface water management permit be modified if necessary to comply with modifications imposed by other public agencies. The District's regulation with respect to the requirement that a project not otherwise be harmful to the water resources within the District is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The District's regulation with respect to the requirement that a project may not be against public policy is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with that criterion. The project will not have an adverse impact on water quality or quantity in receiving waters or adjacent lands. Under the District's regulations, the project would not be permittable if it caused flooding on property owned by other persons. Two concerns regarding off-site flooding were raised by Petitioners: first, the potential for flooding of the Petitioners' property; and, second, the potential for flooding of secondary systems connecting to Lake No. 7 such as private roads in the development. The project would violate the requirements of Section 40D-4.301(1)(a), Florida Administrative Code, which requires that a proposed project provide adequate flood protection and drainage, if raising the weir and berm elevation to 33.6 would cause the level of water in Lake No. 7 to move laterally up the bank and encroach on property owned by Petitioners. However, the Club has given reasonable assurances that the Petitioners own only to the "top of bank" and that raising the weir elevation to 33.6 would not cause water levels to rise above the "top of bank" of the lake. If it is determined in pending state circuit court proceedings that the Petitioners own beyond the "top of bank," any permit for the Club's project might have to be modified to avoid flooding the Petitioners' property. With respect to potential flooding of secondary systems, such as adjacent roadways, raising the elevation of water in Lake No. 7 would decrease the capacity of the storm sewers draining into the Lake. However, the proposed modifications would not increase the area of impervious surface in the drainage basin or decrease the size of the lake, and water levels in the roadways probably would not rise much higher than under present circumstances. The existing storm sewer system is only designed for a 10-year storm event, so the supplemental effect on roadway flooding from retaining a 100-year storm event in Lake No. 7 probably would be negligible. The Club gave reasonable assurances that any increase in water levels on the roadways from the proposed modifications would not be considered a significant adverse effect because it still would not affect public access. Sarasota County's land development regulations allow flooding in streets of up to 12 inches for a 100-year storm event, nine inches for a 25-year storm event, and six inches for a 10-year storm event. No portion of the proposed project area is within the 100-year floodplain. The project will not have an adverse effect on water quantity attenuation or cause flooding of the Petitioners' property or secondary systems, such as adjacent roadways. Petitioners have protested the effect that this project will have on water quality within Lake No. 7, itself. Surface water quality standards do not apply within a stormwater pond. Stormwater ponds are essentially pollution sinks intended to receive polluted runoff. Where there is no discharge from a pond, water quality treatment is irrelevant. Lake 7 is not a "water resource within the District" pursuant to Section 40D-4.301(1)(j), Florida Administrative Code, and potential impact on water quality in Lake No. 7 should not be considered. Section 40D-4.301(1)(j) limits the issues to be considered by the District to downstream water quality, water quantity, floodplain impacts, and wetlands impacts. The commingling of wastewater effluent treated to a level of advanced secondary or advanced waste treatment (reuse water) would improve water quality within a stormwater treatment pond at least 90 to 95 percent of the time. Stormwater is very low quality compared to reuse water. In most respects, reuse water also will be better quality than the well water presently being used to augment the pond. It is expected to be better quality than unimpacted water in the receiving waterbody with respect to nitrogen content and only slightly worse with respect to phosphorus content. The addition of reuse water should not promote more algal growth; rather, it should reduce the likelihood of algal growth. It also should not increase the incidences of fish kills in Lake 7. Nor should it alter the nutrient concentrations in Lake 7 so as to result in an imbalance of the natural population of aquatic flora and fauna. In the draft permit originally proposed to be issued to the Club, permit conditions required that water quality be monitored at the point of discharge to waters of the state. This requirement was eliminated from the revised permit as the District determined that it was not necessary in light of the modification of the system to retain the 100-year storm event. The subject design does not account for recovery of the water quality treatment volume within a specified period of time. However, there is no such requirement in District rules when a pond entirely retains the 100-year storm event, as is the case with this project. Even if there were a discharge from the surface water management system in a storm event up to and including a 100-year storm event, the Club gave reasonable assurances that water quality standards in the receiving waterbody would not be violated because of the effects of dilution. This project will not cause discharges which result in any violations of applicable state water quality standards for surface waters of the state. Based on a number of factors, including the peak rate factor, the curve number and the seasonal high water elevation, the water level in Lake 7 would reach an elevation of 33.57 if a 100-year storm event occurs. This results in the retention of the 100-year storm in Lake 7. The District only considers the 100-year storm event, by itself. It does not consider other rainfall events before or after it. However, the District does presume that ponds are at their seasonal high water level when the 100-year storm event occurs and that the ground is saturated. With respect to the seasonal high water level, there was substantial conflicting testimony. The Club's consultant used a seasonal high water level of 31.0' for Lake No. 7 in his calculations. This was based on a geotechnical engineering report prepared by Ardaman & Associates. A seasonal high water elevation of 31.0' was also used in the original permit application in 1985. In concluding that the seasonal high water level should be 31.0, the Ardaman report relied on several assumptions, including plugging of the underdrain and overflow weir and no discharges into or pumping out of the lake. These assumptions were made to establish an historical water level. The Petitioners' consultant disputed the determination in the Ardaman report that the seasonal high for Lake No. 7 was 31 on the grounds that the report indicated groundwater levels of 32.8 on three sides of the lake. He also felt that water levels would rise in the lake over time as a result of it being, allegedly, a closed system. While he did not have an opinion as to what the appropriate seasonal high should be, he felt it would be higher than 31 but lower than 32.8. However, he did no modeling with respect to calculating a seasonal high water level and would normally rely on a geotechnical engineer, such as Ardaman & Associates, to calculate seasonal high water levels. The District generally does not receive information as extensive and detailed as that included in the Ardaman report when it reviews permit applications. Among other things, the Ardaman report indicates a gradient across Lake No. 7 which makes the determination of the seasonal high for the lake difficult. The groundwater flow gradient results from the fact that the elevation of Lake No. 6 is approximately three feet lower than the elevation in Lake No. 7. The elevation determined by Ardaman may well be conservative in that the seasonal high of 31 is above the midpoint of the gradient. Although Lake 7 will be designed as an essentially closed system, it will have inflow from rainfall, surface runoff, introduction of reuse water and groundwater inflow, and outflows by way of evapotranspiration, withdrawal for irrigation purposes, and groundwater outflows. To alleviate any concerns about the validity of the seasonal high, it would be reasonable to include a permit condition requiring the Club to monitor the water level in Lake 7 on a daily basis, using staff gauges, after modification of the control structure. If such monitoring indicated that the seasonal high water level exceeds 31.0, the District could consider options to address that situation, including reducing the level at which reuse water is introduced into the lake or requiring water quality monitoring at the point of discharge to receiving waters. Groundwater quality is regulated by the Department of Environmental Protection, not by the District. The DEP permit issued to Sarasota County for disposal of reuse water at the Club golf course requires the installation of two groundwater monitoring wells, one in fairly close proximity to Lake No. 7. The Overlooked Pond There is a small retention pond northwest of Lake 7, near lot 113. Neither the Club nor the District considered the effect of the Club's late modification of its application on the retention pond northwest of Lake 7 and adjacent properties. Lake 7 and the retention pond to its northwest are connected by an equalizer pipe. As a result, water levels in the pond will be affected by water levels in Lake 7. There was no evidence as to the elevations of the banks of the retention pond. There was no evidence as to whether the modifications to the Club's application will result in flooding of properties adjacent to the pond. There was no evidence that the Club owns or controls the retention pond or the properties adjacent to it that might be affected by flooding that might result from the modifications to the Club's application.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Southwest Florida Water Management District enter a final order denying the Club's amended application. RECOMMENDED this 19th day of October, 1995, in Tallahassee, Florida. J. LAWRENCE JOHNSTON 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 19th day of October, 1995. APPENDIX TO RECOMMENDED ORDER, CASE NO. 95-2196 To comply with the requirements of Section 120.59(2), Fla. Stat. (1993), the following rulings are made on the parties' proposed findings of fact: Petitioners' Proposed Findings of Fact. 1.-2. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease. Accepted and incorporated. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease and from which the western extent of the Club's leasehold interests in Lake 7 can be determined. Accepted and incorporated. But the topographic survey, together with other evidence, does show the eastern extent of the Petitioners' property in relation to the "top of bank" of Lake 7 and the western extent of the Club's leasehold interests in Lake 7. Rejected as contrary to the greater weight of the evidence that uses must be "specifically authorized" in that the lease authorizes the use of the premises for a "golf course," which is presumed to include uses inherent to the operation of a golf course that may not be further specified in the lease, such as drainage facilities, like Lake 7, and facilities for irrigation of the golf course. Otherwise, accepted and incorporated to the extent not subordinate or unnecessary. Rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as contrary to the greater weight of the evidence that the Club does not pay for the maintenance of Lake 7, at least as between the Club and its lessor, which is the subject of the pertinent lease provision. (There was evidence as to a dispute between the Club and the Petitioners, or at least some of them, as to who is responsible for maintenance of land in the vicinity of the western extent of Lake 7 and the eastern extent of the Petitioners' property. Rejected as contrary to the greater weight of the evidence. Rejected as contrary to the greater weight of the evidence to the extent that there are "A" parcels between lots 115 through 120 and Lake 7. Otherwise, accepted and incorporated. Accepted and incorporated. Not clear whether all of the activities listed in the second sentence are done in the entire area up to the water's edge but, otherwise, accepted and incorporated. Accepted, but subordinate to facts contrary to those found, and unnecessary. Accepted; subordinate to facts found. Rejected. The intent of the parties is not clear and is the subject of litigation in state circuit court. 17.-18. Accepted that some probably used the words "to the water's edge"; others may have said "to the lake" or "to the approximate high water line." Regardless of what they said, the legal consequences are being litigated in state circuit court. Subordinate to facts contrary to those found, and unnecessary. 19.-20. Accepted and incorporated to the extent not subordinate or unnecessary.. Last sentence, accepted but subordinate and unnecessary. The rest is rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. The evidence was sufficient to place on Exhibit M-16 the boundary lines of the "A" parcels, as depicted on the Alberti boundary survey that was attached to the individual deeds to all of the "A" parcels, in relation to the "top of bank" of Lake 7 and other topographical features depicted on Exhibit M-16. The 0.679 acre total for the "A" parcels was merely transcribed from the Alberti boundary survey (probably incorrectly, as the boundary survey seems to indicate the acreage to be 0.674, plus or minus.) Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, it will spread more than before the modifications, up to a maximum spread of approximately ten feet. Rejected as contrary to the greater weight of the evidence. The Club gave reasonable assurances that the spread would be contained within its leasehold interest. However, consideration would have to be given to modifying the permit if the state circuit court determines in the pending litigation that the easterly boundary of the "A" parcels lies to the east of the "top of bank." Accepted and incorporated to the extent not conclusion of law. Accepted. Self-evident and unnecessary. Accepted and incorporated. Accepted, but subordinate, and unnecessary. Accepted and incorporated. Rejected as contrary to the greater weight of the evidence. It does not prohibit it; it just does not authorize it. It provides that authorization may be obtained by permit modification. Accepted and incorporated to the extent not subordinate or unnecessary. 32.-36. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) 37. Rejected as contrary to the greater weight of the evidence that discharges will be "likely." (Accepted and incorporated that no discharges are expected as a result of storm events up to and including a 100-year storm event unless preceding conditions predispose the system to discharge during a 100-year storm event.) 38.-39. Accepted but subordinate and unnecessary. (As for 39., very little construction will be required for the proposed project.) Rejected as contrary to the greater weight of the evidence. First, Lake 7 will not be "maintained" at 31'; rather, when it falls below 30.5', a half inch will be added. Second, it is not clear that the Ardaman report established an "artificially low seasonal high water level." (There is a hydraulic gradient across Lake 7 from east to west, approximately. The Ardaman report assumed no flow into or out of Lake 7; it also assumed no pumpage into or out of the lake.) Rejected as contrary to the greater weight of the evidence that it is based "solely" on that assumption. Accepted and incorporated that it is based on that and on other assumptions. Accepted and incorporated. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) Rejected as not supported by evidence. Rejected as contrary to the greater weight of the evidence to the extent that the impact is obvious--the water level in the pond will be approximately equal to the water level in Lake 7. Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, so will the water level in the pond. 47.-48. Accepted and incorporated. 49.-50. Accepted but subordinate and unnecessary. 51.-52. Accepted and incorporated. Respondents' Proposed Findings of Fact. 1.-7. Accepted and incorporated. 8. Rejected as contrary to the greater weight of the evidence in that there was more to the application than just substitution of reuse for well water. 9.-10. Accepted and incorporated. 11. Accepted and incorporated to the extent not subordinate or unnecessary. 12.-22. Accepted and incorporated. Rejected as not proven. (The two District witnesses disagreed.) Even if true, subordinate to facts contrary to those found. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted and incorporated. Accepted and incorporated to the extent not conclusion of law. 28.-29. Accepted; subordinate to facts found, and in part conclusion of law. 30. Accepted. First sentence, incorporated; second sentence, subordinate to facts found, and in part conclusion of law. 31.-35. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted but subordinate to facts contrary to those found. 39.-40. Accepted and incorporated to the extent not subordinate or unnecessary. 41.-43. Accepted and incorporated. Accepted and incorporated to the extent not conclusion of law. Last sentence, accepted and incorporated to the extent not conclusion of law; rest, accepted but subordinate to facts contrary to those found, and in part conclusion of law. Accepted and incorporated to the extent not subordinate or unnecessary. Accepted, but subordinate, and unnecessary. Accepted and incorporated. First sentence, accepted but subordinate to facts contrary to those found; second sentence, accepted and incorporated to the extent not conclusion of law. Accepted and incorporated to the extent not subordinate or unnecessary. 51.-52. Accepted and incorporated. 53.-55. Accepted, but subordinate to facts found, and unnecessary. 56. Accepted and incorporated. 57.-62. Accepted and incorporated to the extent not subordinate or unnecessary. 63. Accepted and incorporated to the extent not conclusion of law.

Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that application number 07256-F be APPROVED subject to the special conditions set forth above. DONE AND ORDERED this 15th day of July 1987, in Tallahassee, Leon County, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399-1550 904/488-9675 Filed with the Clerk of the Division of Administrative Hearings this 15th day of July 1987.
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.

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 ultimate issue to be addressed in this proceeding is whether the Applicants should be granted a dredge and fill permit. Petitioner contends that the Applicants have failed to provide reasonable assurances that the short-term and long-term effects of their proposed activities will not result in violations of the Department's water quality standards for both surface water and groundwater. The Applicants and the Department contend that reasonable assurances have been provided.
Findings Of Fact The Applicants are the owners of a 1,248-acre parcel of land located at the intersection of State Road 710 and State Road 711 in northern Palm Beach County, Florida. The Applicants are proposing to develop an industrial park known as "Palm Beach Park of Commerce" (PBPC). PBPC will provide sites for tenants to carry on various commercial and industrial activities. In order to prepare the site for development, the Applicants have designed a surface water management system. In order to develop the system, the Applicants must conduct dredging and filling activities in areas where the Department of Environmental Regulation has permitting jurisdiction. The Petitioner is an association of home owners within a single family residential development known as "Caloosa." The development is located to the southeast of the proposed PBPC. Surface and ground water flows from the PBPC site are toward Caloosa. Residents of Caloosa and members of the Petitioner are entirely dependent on private individual wells for their drinking water. The surficial aquifer is the only viable source of drinking water. The proposed PBPC surface water management system would allow water to drain from the site into an excavated canal which would essentially follow the perimeter of the site. The canal would discharge at the southeast corner of the site into the Caloosa Canal, which runs through the Caloosa residential development. The Caloosa Canal is designated as a Class III water body. The Caloosa Canal drains into the "C-18 Canal," which is maintained by the South Florida Water Management District. The point at which the Caloosa Canal discharges into the C-18 Canal is approximately 2.4 miles from the PBPC site. The C-18 Canal is designated as a Class I water body. The C-18 Canal ultimately discharges into the Loxahatchee River Basin, a Class II water body, which is located approximately 12.9 miles from the PBPC site. It is possible that during some periods of the year, water from the PBPC site would ultimately find its way to the Jonathan Dickinson park, where water has been designated as "outstanding Florida waters." It is approximately 13.2 miles from the PBPC site to the Jonathan Dickinson Park. The PBPC site is a high, marginal, stressed Everglades system. It is a prairie or pine flatwood area. During periods of heavy rainfall, water covers most of the site. During dry periods, there is standing water only in depressions. Approximately 200 acres of the site are inundated with water during a sufficient portion of the year to support predominantly wetland vegetation. Approximately 24 acres of the wetlands on the site are directly connected to drainage ditches that presently rim the site. The ditches are connected to the Caloosa Canal so that these 24 acres are ultimately connected through canal systems to the Loxahatchee River. These wetland areas, which will be hereafter referenced as "jurisdictional wetlands," are the only wetland areas other than the existing drainage ditches over which the Department of Environmental Regulation asserts jurisdiction under its Rule 17-4.28, Florida Administrative Code. As a part of its surface water management system, the Applicants propose to maintain 133.7 acres of the wetlands on the site in their natural condition. These wetland areas would be incorporated into the surface water management system so that surface water would flow into the wetlands, then through culverts or drainage ditches into the perimeter canal. The remaining wetlands on the site, including all of the "jurisdictional wetlands," would be filled. The wetlands on the PBPC site perform a significant water quality function. The wetlands serve as a filtration system. Wetland vegetation removes nutrients and turbidity from surface water before it is discharged into the canals and ultimately into the Loxahatchee River. The wetlands that the Applicants propose to preserve on the site would continue to perform that beneficial function. In order to mitigate the loss of the wetlands that would be filled, the Applicants propose to create approximately 85 acres of new wetland areas and to vegetate these areas. These artificially created wetlands, if properly constructed, vegetated and maintained, would perform the same beneficial functions as the natural wetland communities. The Applicants have proposed to introduce several safeguards into their water management system to assure that the quality of surface and ground water in the area will not be adversely impacted. The preservation of 133 acres of natural wetland areas and the creation of approximately 85 acres of artificial wetland areas is one of these safeguards. In addition, the surface water management system includes the creation of swales around water bodies so that the first one inch of stormwater runoff on the site will not drain directly into surface water bodies. By retaining the first one inch of runoff, pollutants contained in stormwater runoff will be retained on the site and will not enter surface or ground waters. Each commercial or industrial site at PBPC will be required to retain an additional one inch of stormwater runoff on the individual site. This will serve to filter pollutants out of stormwater runoff even before the runoff reaches the overall surface water management system in which one inch of runoff will also be retained on site. The Applicants have also agreed to establish a surface water quality management program to prohibit the discharge of any industrial waste into the surface water management system and to have the surface water management system maintained by the Northern Palm Beach Water Control District. There are further safeguards proposed by the Applicants. The Applicants have agreed to prohibit the most potentially hazardous industrial activities from being undertaken on the site. Applicants have also agreed to require each individual site plan to be reviewed by local government, the South Florida Water Management District, and the Department of Environmental Regulation so that potential water quality problems connected with site-specific uses can be identified and, if necessary, prohibited. The Applicants have agreed to establish an environmental liaison officer whose function will be to monitor all development on the site and report routinely to local government, the South Florida Water Management District, and the Department of Environmental Regulation regarding environmental issues. In order that any potential groundwater pollution can be detected and, if necessary, steps taken to remove pollutants from the groundwater, the Applicants have agreed to establish well- monitoring systems for the project as a whole and for individual sites. Individual site plans have not yet been formulated. It is not practical or possible to design water monitoring programs for the individual sites at this time. Once the nature of activities at a site are known, monitoring programs can be effectively set up and maintained. In the event that surface or ground water contamination occurs, it can be detected through monitoring programs, and the contaminants can be removed. The Applicants have provided reasonable assurance that the short-term and long-term effects of the construction of the PBPC water management system will not result in violations of the Department's water quality standards for surface or ground water. By use of turbidity screens during construction, short-term impacts will be negligible. Absent any construction on the site beyond the creation of the surface water management system, it is likely that the quality of water leaving the PBPC site will be as good or better than at present. Since the Applicants have not yet located tenants or made individual site plans for commercial and industrial activities within PBPC, it is not possible to determine if some specific activity in the future could operate to cause violations of the Department's water quality standards. In order that there be such assurances, the Applicants have agreed to subject individual site plans to review by local government, the South Florida Water Management District, and the Department of Environmental Regulation. In the event that a future tenant is not able to provide required assurances, the use can and should be prohibited, and can be prohibited by regulatory agencies as a condition of permits issued to the Applicants. Water quality violations presently occur in the Caloosa Canal and the C-18 Canal. The safeguards proposed by Applicants reasonably assure that the implementation of the proposed water management system will not exacerbate or cotribute to these violations. There is approximately an 11-square-mile area which drains into the Caloosa Canal through the outfall at the southeast corner of the PBPC site. The PBPC site constitutes approximately two square miles of this area. The remaining nine square miles are located to the north and west of the PBPC site. These off-site areas are undeveloped and have an ecology very similar to the presently undeveloped PBPC site. The evidence would not establish a finding that development of these off-site parcels together with development of the PBPC site would cumulatively result in water quality violations of surface or ground waters. The Applicants will be required to obtain permits to construct a wastewater treatment facility on the PBPC site. Whether any proposed wastewater treatment system will meet the standards of regulatory agencies would appropriately be considered in later proceedings. Similarly, individual tenants will, in some cases, be required to operate wastewater treatment systems that pretreat industrial waste before it is introduced into the system-wide wastewater treatment system or before it is otherwise removed from the site. These systems would also be subject to future permitting proceedings. Some of the potential activities that could be carried on by tenants at the PBPC involve the use of volatile organic compounds and other hazardous toxic substances. If proper techniques are not followed for the handling of such substances, or if some accident occurs, the substances could be introduced into the surface and ground waters. Review of each individual site plan and the establishing of systems for properly handling toxic substances can reduce the possibility of incidents occurring. Human frailties existing as they do, however, it is not unlikely that such an incident will occur. If such an incident occurs, it is vitally important that the contamination of surface or ground water be quickly detected and that steps be taken to remove the contaminant. The establishing of proper monitoring systems can reasonably assure that the contamination is identified. Techniques do exist for removing contaminants from surface and ground waters. Since individual tenants and site plans have not yet been established, it is not possible to make any finding as to whether any individual tenant or site plan might operate in such a manner as to cause violations of the Department's water quality standards. It is therefore appropriate that individual tenants and site plans be subjected to further review by appropriate regulatory agencies before they are permitted to operate on the PBPC site. The Applicants have agreed to such a review process. Since surface water flows into the Caloosa Canal can be controlled through the outfall structure at the southeast corner of the PBPC site, it appears practical to isolate any contaminant that might enter the surface water and to remove it. Groundwater flows in the aquifer lying below the PBPC site are very slow--less than one-tenth of one foot per day. Given such flow rates, it is likely that any contaminants that enter the groundwater can be detected and effectively removed. Even given the implementation of the best procedures for handling toxic substances, the best monitoring program for detecting accidental releases of the substances, and the best systems for removing the substances from surface and ground waters, there is some possibility that an accident could occur, that a contaminant would not be detected, and that violations of the Department's water quality standards could occur as a result in the Caloosa Canal or in the groundwater which underlies the Caloosa development and provides drinking water to residents there. The result of such an incident could have very serious impacts. The introduction of toxic substances into the surface waters could cause a substantial damage as far downstream as the Loxahatchee River Basin. Contamination of the groundwater could result in a loss of water supply to residents or in serious public health consequences. While such possibilities exist, they appear unlikely given the safeguards that have been proposed for PBPC. The Applicants do not propose to undertake any dredging or filling activities in any navigable waters.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That the Department of Environmental Regulation enter a final order issuing a permit to Caleffe Investment, Ltd., Worthington Enterprises, Inc., to conduct the dredging and filling activities proposed by the Applicants. To ensure that state water quality standards will not be violated, the conditions cited in the Department's Intent to Issue notice dated October 22, 1982, should be made a part of the permit. In addition, the following conditions should be made a part of the permit: All individual site plans within PBPC should be subject to the Department's permitting processes in accordance with Rule 17-4.28, Florida Administrative Code, and other provisions of Chapter 17, Florida Administrative Code, and Chapter 403, Florida Statutes, as may apply. The Applicants should be required to post bond in a sufficient amount to assure proper implementation and operation of monitoring systems for individual sites and to assure that adequate funds are available to remove and properly treat contaminants that might enter surface or ground waters as a result of accidents.
