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.
The Issue The issue in this case is whether the development order issued by Polk County for Robert Crowder's development known as Paradise Country Estates complies with Chapter 380, Fla. Stat. (1991). The Department of Community Affairs' Petition for Appeal of Development Order (the DCA Petition) alleges that the development order is contrary to Polk County's 1985 comprehensive plan for the following reasons: Paragraph 11 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 9, Objective III, "Natural Resources," of the Land Use Element (LUE) of the 1985 Plan. Policy 9 states: "Structures should be placed in a manner which will not adversely affect the natural flow regime and which will not reduce the recharge capabilities." Paragraph 12 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 10, Objective III, "Natural Resources," of the LUE. Policy 10 states: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Paragraph 13 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 11, Objective III, "Natural Resources," of the LUE and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Respectively, these policies state: 11. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Paragraph 14 of the DCA Petition alleges that the development order is contrary to a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources," which describes the Green Swamp as a "rare and unique land area resource for conservation consideration" and also states: The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Paragraph 15 of the DCA Petition alleges that the development order is contrary to the following section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships": The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. Paragraph 16 of the DCA Petition alleges that the development order is contrary to Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan: "Protect or improve existing ground and surface-water quality." Paragraph 17 of the DCA Petition alleges that the development order is contrary to Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE: Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. Paragraph 19 1/ of the DCA Petition alleges that the development order is contrary to Policy 2, Objective IV, "Residential Uses," in Part V of the LUE: Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. Paragraph 20 of the DCA Petition alleges that the development order is contrary to Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code). 2/ Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Paragraph 21 of the DCA Petition alleges that the development order is contrary to Section 5-2(4) of Polk County Ordinance 81-28. 3/ Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Paragraph 22 of the DCA Petition alleges that the development order is contrary to Section 6-2(3)(a) of Polk County Ordinance 81-28. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site.
Findings Of Fact The Proposed Project and Location. The project site is on Dean Still Road in Polk County, approximately 2 miles west of State Road 33. It is approximately 6 and 1/2 miles from Polk City and 15 miles from the City of Lakeland. The proposed project is comprised of 356 lots on approximately 1280 acres with a gross density of 1 unit per 3.6 acres. Although the average lot size varies, the project was reviewed under the Southwest Florida Water Management District's (SWFWMD) criteria for rural development which requires that at least 90% of the lots be at least 2 acres in size (excluding jurisdictional wetlands), and 10% of the lots be at least 1 acre (excluding jurisdictional wetlands). The site has been zoned Rural Conservation under Polk County's Zoning Code for approximately 12 years. This designation allows a density up to 1 unit per acre. Individual water wells and on-site waste disposal systems (septic tanks) will be utilized for each home. There are no water or sewer extensions proposed for the site or for adjacent areas by any governmental entity. Access to the site from Polk City is along Dean Still Road, which is unpaved at this time. The County has plans to pave it in the near future. Of the 1280 acres comprising the project site, 362 acres have been claimed as jurisdictional wetlands and approximately 642 acres have been mapped within the 100-year floodplain by the Federal Emergency Management Agency (FEMA). 51 of the lots platted in the project are entirely within the FEMA 100- year flood plain. Several other lots contain large portions within FEMA 100- year flood plain. Despite the significant amount of wetlands and floodplains on the site, the project is designed so that no net loss will occur in the floodplains and less than 1% (.59%) of the jurisdictional wetlands will be impacted by development. Impervious conditions on the site will only increase by 2.8% after development. All structures will be set at or above the 100 year flood elevation, as calculated by the project engineers, and will be constructed in accordance with the County's flood protection standards. The project is designed so that post-development runoff is less than pre-development runoff and post-development drainage basins conform to pre-development drainage basins. Existing drainage patterns for the site are designed to be maintained. The property comprising the project has been used through the years for a variety agricultural purposes, including harvesting watermelons, soybeans, corn, and silage. It has been drained and ditched to facilitate these activities. It is currently being used for grazing cattle. A sod farm is located to the south of the property. Additional cattle grazing lands run south from there to Polk City. To the north of the site are ranchlands which run to the border of the Withlacoochee Wildlife Area. Immediately to the west of the site are 20-30 scattered mobile homes and additional ranchlands in a subdivision known as Evans Acres. This subdivision was initially approved by DCA in 1983, and was comprised of 48 lots on approximately 1,290 acres. The original lots ranged in size from 5 to 60 acres. Apparently, individuals have since split their lots and many of the existing lots are 2 to 5 acres in size. A few of the original lots are used for both residential and ranching purposes. Including the large and small lots, there are approximately 163 lots on the property comprising Evans Acres. On the property directly to the east of the site are approximately 16 mobile homes along Melody Lane. These existing homesite numbers are small and scattered when compared to the 356 lots proposed for Paradise Country Estates. Approximately 120 families live in the general vicinity of the proposed project. The Green Swamp. The project is within the Green Swamp Area of Critical State Concern (ACSC). The site is within the drainage basin of the Withlacoochee River, which has been designated an Outstanding Florida Water (OFW) and is approximately three and a half miles to the north. The Green Swamp ACSC was designated by the Legislature. Chapter 79- 73, 380.0551, Florida Statutes (1991). It was the second area to be designated and now is one of only four areas in the State retaining this designation. The Green Swamp was designated because the area's natural resources were considered to be of regional and statewide importance and because of concerns that uncoordinated development could endanger these resources. The Green Swamp is a regionally significant area for recharge of the Floridan Aquifer. The Green Swamp is unique because the top of the Floridan Aquifer is at or near the surface over much of the area. This creates what is known as the potentiometric high of the Floridan Aquifer. The potentiometric high pressurizes the Floridan Aquifer, permitting it to be used for drinking water wells. The Florida Aquifer serves as the principal source of drinking water for central Florida. It supplies the entire State with about 48 percent of its ground water supply. The potentiometric high also serves to hold back salt water intrusion into the Floridan. Recharge is important in maintaining the potentiometric high of the Floridan Aquifer. Although the Green Swamp has been characterized as a recharge area for the Floridan Aquifer, the actual recharge capabilities of the Green Swamp vary considerably throughout the region. Some areas within the Green Swamp, such as the high, dry, sandy ridge on the eastern boundary of the Green Swamp clearly are high recharge areas. In some areas, the Floridan Aquifer rises essentially to the ground surface, with no confining layer above it. In those areas, a considerable amount of surface water filters into the Floridan Aquifer. In other areas, including in the vicinity of the project site, recharge capability is considerably less. See "G. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code, (3) Ground Water Recharge." The head waters of several rivers, including the Withlacoochee River, are in the Green Swamp. Polk County's Comprehensive Plan. Polk County's Comprehensive Plan, as amended by Polk County Ordinance 85-08 (Ordinance 85-08), is referred to as Polk County's 1985 comprehensive plan, or the 1985 plan. It includes a Land Use Element (LUE) and a Conservation Element. The Land Use Element. The 1985 Plan is a "policy plan." As a "policy plan," the LUE does not map land use classifications or densities or intensities of development. The different parts of the plan must be considered together to ascertain their meaning. As stated in the Foreward to the LUE: The Policy Plan is a flexible and realistic guide to future public decisions. Existing conditions are first determined and analyzed. Then, community goals are identified providing a process of finding out where we are and where we want to go. * * * . . .. The challenge is to determine the means of achieving the identified community goals at minimal cost and the least possible hardship on any segment of our society. Under the policies planning process this is accomplished by developing all possible alternative courses of action that will advance the community toward the desire goal. The policies are then a general statement of purpose and outlining broad principles toward which the plan is guided in the implementation stage. A policy plan does not detail specific actions or locations on a map. Rather it provides a broad framework within which day-to-day decisions are made in a consistent manner toward an identified goal. The ultimate product of those community goals will be the heritage of Polk County's future. At 4-2, the LUE discusses the need to give attention to "the proper distribution of population densities in keeping with sound planning practices, the physical capabilities of the land, and the relationship of the population and housing densities to existing or proposed transportation facilities and other community services." It then speaks to "Retention of Open Spaces": A second potential problem to be faced, as urban growth continues, is the potential loss of the open space characteristics that now contribute substantially to its desirability as a community in which to live and visit. To a large extent, the desirable characteristics are provided by extensive agricultural areas. Such uses are compatible with residential and other types of urban land uses and should be encouraged to remain to the maximum extent possible. Desirable open space is also presently provided by . . . wetland areas not suited for urban development. By encouraging such areas to remain in their present condition, a substantial amount of open space can be retained to provide the needed visual relief and openness necessary within a highly urbanized community. At 4-5, discussing "Retention of Unique Agricultural Lands," the LUE states that cattle raising and field crops are subject to potential intrusion by urban development and states: "The development of planning techniques, which will encourage the retention of important agricultural lands and provide for orderly urban development, thus becomes a matter of considerable importance." The Goals, Objectives, and Policies (GOPs) of the LUE starting at 5-1 include the following: General Goal: To maintain productive and mutually compatible use of lands and waters within Polk County in a manner consistent with the economic, physical and social needs, capabilities, and desires of Polk County and its citizens. Objective I - Agricultural Uses: To ensure that a sufficient quantity of appropriate lands are available and protected for productive agricultural uses necessary to a sound economic base. Policies: * * * 2. Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. * * * 5. Provide all possible incentives for the retention of lands into agricultural production. * * * Objective III - Natural Resources Minimize adverse impacts of development on valuable natural resources including the protection of water quality and quantity in surface and ground waters. Policies: * * * 2. The subdivision and platting of land shall be permitted in accordance with the zoning district applied to the property and in compliance with the Polk County Subdivision Regulations and Flood Protection/Surface Water Management Ordinance. * * * Site alteration should be permitted only when such alteration will not adversely affect the natural flow regime or the natural recharge capabilities of the site. Site alteration should be permitted only when such alteration will not result in the siltation of wetlands or reduce the natural retention and filtering capabilities of wetlands. Site alteration activities should provide for water retention and settling facilities; should maintain an overall site runoff equivalent to the natural flow regime prior to alteration and should maintain a runoff rate which does not cause erosion. * * * Storm water runoff should be released into the wetlands in a manner approximating the natural flow regime. Structures should be placed in a manner which will not adversely affect the natural flow regime and which well not reduce the recharge capabilities. Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. Objective IV - Residential Areas To ensure that an adequate supply of appropriately located lands are available for the development and maintenance of residential areas that can be efficiently and effectively provided with necessary public facilities and services. Policies: Promote and encourage the provision of a wide range of housing opportunities, in appropriate locations, to permit a choice of housing types to suit the particular needs of all citizens. Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. * * * Encourage new residential development that can be effectively served by the existing transportation facilities. Promote new residential development in non-urban areas, that is properly designed to combine with future adjacent development, to create a neighborhood of sufficient size to facilitate the efficient and effective provision of all necessary public facilities and services. Part VI of the LUE, entitled "Alternate Approaches," discusses the pros and cons of different concepts for planning and managing of growth. It settles on a "Resource-Responsive Concept" as the preferred growth alternative. This concept holds in part: Wherever possible, future growth should be encouraged to take place in or near established urbanized areas. Scattered growth incapable of functioning as meaningful self-contained communities should be discouraged. And it is preferable that the urbanizing area, as it extends over extensive areas within the County, not be developed in one continuous, monotonous maze of residential, commercial, and industrial uses - but that there be open space provided at appropriate intervals so as to provide visual relief and a sense of scale to the overall urban community. Such open space areas can be productively utilized for agricultural and conservation purposes or recreation areas, public facilities and services required. It is proposed that the most appropriate urban growth concept to meet such guide-lines and the policy statements of this land use plan be a resource-responsive growth concept. Under this concept, urban growth and development will be guided and encouraged with respect to its responsiveness to the natural and human resource capabilities of the County. Within any given area of the County, the resources will be careful evaluated in terms of their capability to support growth, and the physical form and intensity of development will be then shaped to provide the physical form and intensity of development will be then shaped to provide a balance with such resources. Prime resources to be considered are as follows: Natural Resources Topography and soil conditions Vegetation and tree cover Wildlife habitats present Drainage characteristics; relationship to rivers and lakes Natural water supply capabilities General aesthetic qualities Human Resources Transportation facilities (roads, railroads, airports) Available water supply and sewage facilities Community facilities, such as schools, parks, libraries Protective services, such as fire and police Established land uses within the area Economic conditions and potentials. Part VII of the LUE, entitled "Implementation," states: "Initial implementation of a Comprehensive Plan and initiation of the continuing planning process for growth management requires the establishment of principals and standards for measurement of proposed activities against the adopted policies of the community." It includes a section entitled "Principles and Standards for the Control and Distribution of Population Densities and Structural/Development Intensity," which provides in part: All Types of Urban Development: * * * Each new development or land use should follow sound land planning principles to maximize site advantages, avoiding when possible, adverse impacts on the natural resources and hazards to health, safety, or general welfare. * * * Residential Development: Low-density single-family development (1-4 units/acre), other than rural residences related to agricultural operations, shall be located in areas capable of being developed into stable, cohesive neighborhoods. In a section entitled "Legal Requirements of Implementation," it states that "all actions taken by local government, whether in the form of permitting private development to occur or in the provision of public facilities and services, are required to be fully consistent with the adopted Comprehensive Plan. The plan, once adopted, must occupy a central position in the consideration of all proposed development." In another section, entitled "Coordination with Other Plan Elements," it states that the "land use element cannot be implemented alone [but] must be coordinated with the [other elements]." In another section, entitled "Needed Improvements in the Zoning Ordinance," it is recognized that "it will be essential that a thorough review of the zoning ordinance be undertaken and that the ordinance be revised as appropriate to achieve consistency with overall planning objectives." It acknowledges that there were "major identified deficiencies in the current zoning regulations" and advises that "the following needs among others should be addressed as a minimum in making revisions to the zoning ordinance": "Revision of the Density Requirement in Residential Districts." Despite the admonitions in the 1985 Plan, to date there has been no revision of the land use classifications, densities, or intensities in the County's zoning code. As before the 1985 Plan was adopted, zoning in the Green Swamp ACSC remains Rural Conservation (RC) and allows up to one unit per acre residential development. The Conservation Element. Part II of the Conservation Element of the Polk County Comprehensive Plan is a "Summary of Natural Resources." At 2-18, there appears a section entitled "Rare and Unique Natural Resources," which describes the Green Swamp, as well as other natural resources in the County, as a "rare and unique land area resource for conservation consideration." At 2-19, as amended by Ordinance 85-08, this element of the comprehensive plan also states: This area comprises the hydrologic heartland of Central Florida and contains the headwaters of the Withlacoochee, Hillsborough, Peace and Oklawaha Rivers. The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Part IV of the Conservation Element is a "Summary of Special Problems, Areas, Issues, and Relationships." Starting at 4-2, it addresses the following: Displacement . . .. Cities in Polk County have historically developed on the ridges and the urbanized areas are spreading outward rapidly into the prime citrus lands and the "marginal" (flood prone) lands. There is considerable concern about urban development in wetland soils and flood prone areas. The double barreled concern for development in wetland soils and wetland areas is that they might well serve valuable natural functions and the private and public problems created by development subjected to flood damages. This property damage promotes public pressure for drainage in wet areas. The issue in wetland drainage and flood control is the jeopardy of natural functions that wetlands and water fluctuations provide in natural systems and flood damage costs. . . . [C]oncern for the growing demand for uplands development which steadily displaces [good pasture land] . . . relate[s] to the use of good pasture land for development. Density The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. * * * Water * * * Another area of concern relates to the draw down and recha[r]ge of the Floridan Aquifer and is claimed to be a rational concern of an area much larger than Polk County. * * * Pollution Environmental pollution, as it relates to water, is a major local concern. * * * Water pollution is concerned because of its effects on recreation and tourism. Water degradation and the pollution of lakes and rivers tends to remove the intangible value that Polk County enjoys in thee form of its surface water resources. * * * Also, the related cost issues of municipal sewage treatment and disposal, effluent disposal techniques, septic tank useage are environmentally economic choices to be made by the public. Discussing the topic, "Preservation and Management," starting at 4-4, Part IV of the Conservation Element states in part: Many issues relate to what, how, or when something should be conserved. * * * Lakes, rivers and canals of the county are of concern as sources of flooding and as resources for flood control, if properly managed. Flood prone areas surrounding surface water have been identified for much of the county. These water bodies are also legitimate concerns as the habitat for fish and other wildlife that provide a significant value in their own right. The area of these water bodies are also special scenic and recreational values that contribute to tourism and development. Part V of the Conservation Element is where the "Goals, Objectives and Policies" are found. It start with some general observations, including in part: . . .. It can be expected, therefore, that the natural environment of the county will continue to undergo modification of one type or another in response to the needs of people. . . . The inventory of total space will, therefore, diminish as these changes take place, resulting in corresponding losses within particular categories of natural resources. What is important is that no critical loss of impairment of a natural resource take place; that development be managed so as to create minimum disturbance of the remaining natural resource systems; and that there be compensation replenishments of resources wherever possible. It then lists a General Goal and several resource-specific objectives and policies: General Goal: Maintain, protect, develop and utilized the natural resources in a manner that will balance and replenish the natural ecological systems and will best serve and promote the desired quality of life for Polk County resident, present and future. * * * Water Resource Objective: To conserve and protect the quality and quantity of water resources through proper management. * * * 6. Identify and protect significant acquifer [sic] recharge areas for maximum recharge capability and protect the water available for aquifer recharge. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Protect the functions of the Potentiometric High of the Floridan Aquifer. Prevent further salt-water intrusion into the Floridan Aquifer. Protect or improve existing ground and surface-water quality. Protect the water retention and biological-filtering capabilities of wetlands. Protect the natural flow regime of drainage basins. Rare and Unique Natural Resource Objective: To conserve and protect, through proper resources management, areas having unique natural characteristics and particularly sensitive environmental balance. * * * Policies: Identify all significant areas in Polk County deemed to have unique natural resource characteristics. Encourage proper management of unique wetland areas of the County as a vital water resource. Encourage a proper system for control of development in flood prone and wetland areas to regulate alternation [sic] of the natural system of water retention and storage during periods of heavy rainfall. Preserve and protect, to the maximum extent possible, all delineated areas having valuable unique resource characteristics. Part V of the Conservation Element concludes with a "Summary," which states in part: The objectives and policies set forth above should not be considered as controls to be rigidly applied in every instance of decision-making dealing with the natural environment. Rather, in dealing with resource conservation issues, guidance is preferable to control. . . . A number of potential implementation actions and programs, presented in the following part, will further assist in establishing the direction and scope of conservation activities in the County. Part VI of the Conservation Element is entitled "Implementation." While acknowledging at 6-1 that Polk County cannot establish an implementation program unilaterally, without regard to the co-responsibilities of other governmental authorities at the regional state and federal levels, it states at 6-2 that Polk County "can and should": Utilize the general objectives and policies established by this Element as considerations in all decision making concerning the use and improvement of land within the County. * * * 3. Utilize, to the fullest extent possible, the policies and implementation controls of other elements of the Polk County Comprehensive Plan, and those of other governmental entities having jurisdiction, to further the conservation of natural resources. Starting at 6-3, Part VI discusses the Conservation Element's "Relationship to Other Plans." At 6-4, after stating that the Conservation Element will be largely implemented through the policies and programs of other comprehensive plan elements, Part VI provides: Land Use Element - This element will provide the overall framework for conservation [sic] potentialities through the manner in which land uses are distributed, arranged, and interrelated throughout Polk County. Policies and implementation programs of this element will determine the degree to which new development is properly related to soil types and capabilities, natural habitats, flood prone areas, wetlands and unique resource areas of the County. Land regulatory controls such as zoning, subdivision regulations and development impact reviews provide the basic tools for implementation of the policies of the Land Use Element. Starting at 6-5, Part VI discusses "Guidelines for Implementation." At 6-5, it points out: The nature of conservation policy, being of such broad application and diversity of interest, requires that its effective implementation utilize many approaches, techniques and procedures. Its application is carried out, for the most part, in an indirect way as a by-product of other more direct decisions and actions relation to the development and growth of the County. It is essential, therefore, that Polk County draw upon all possible alternative mechanisms and techniques which will lead to the effective conservation of its natural resource systems. Among the various approaches which Polk County may utilize to further its conservation objectives are the following. * * * Influence in the allocation of resources to achieve the objectives of the conservation plan. Control of events which determine resources allocation in keeping with the conservation plan. * * * Specific procedures and techniques which may be utilized to facilitate the implementation process include the following. * * * 7. Protect natural water bodies and adjacent wetland areas through the regulation of development densities and proper management of stormwater runoff. This would require a cooperative effort with the Water Management Districts in identifying flood plains for various flood frequencies. Polk County's Flood Protection and Surface Water Management Code. Polk County's Flood Protection and Surface Water Management Code was enacted as Ordinance 81-28 and was amended by Ordinance 85-07. Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code. Land Use, Density and Intensity. DCA alleges that the land use, density and intensity of the development Crowder proposes for the site is inconsistent with: (1) the section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships"; (2) a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources"; (3) Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE; and (4) Policy 2, Objective IV, "Residential Uses," in Part V of the LUE. 6/ As previously stated, the 1985 Plan is a policy plan that does not map land use classifications or densities or intensities of development. Crowder's Paradise Country Estates is consistent with the County's Zoning Code, which has not changed since before the 1985 plan, and Zoning Map. The development was not otherwise reviewed for land use, density or intensity. But it is clear that the 1985 plan does not condone exclusive resort to the zoning code to determine the appropriateness of the land use, density and intensity for development in the Green Swamp ACSC. See, especially, the section entitled "Density" in Part IV of the Conservation Element of the Plan. In the Green Swamp ACSC, especially, reference must also be made to the Plan itself. See Part VII of the LUE, entitled "Implementation." It is not found that all residential use on the Crowder property would be, in itself, inconsistent with the 1985 Plan. But, taking into consideration all of its land use, density and intensity provisions, it must be found that the development order issued in this case, especially at its level of density and intensity and especially in the manner of its issuance, is inconsistent with the 1985 Plan. The crux of the problem with this development, like others in the Green Swamp ACSC already permitted by County development orders, is that, first, the 1985 comprehensive plan and the County zoning regulations in place at the time were inadequate and, second, the steps envisioned in the plan to make them adequate have not been taken. For the plan and the zoning regulations to be adequate, and for a development order for a project in the Green Swamp ACSC in Polk County to be consistent with the 1985 comprehensive plan, either: (1) the plan must be amended to map land use classifications, densities and intensities of development in the Green Swamp ACSC; (2) the zoning code must be amended as envisioned in the comprehensive plan for the Green Swamp ACSC; or (3) the County must evaluate development orders for projects in the Green Swamp ACSC on a case- by-case basis for consistency with the comprehensive plan. None of these three possibilities happened in this case. 7/ Flood Plain Delineation. Paragraph 12 of the DCA Petition alleges that the Crowder development violates Policy 10 of Objective III, "Natural Resources," of the LUE: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Specifically, it is alleged that the use of a Federal Emergency Management Agency (FEMA) undetailed "A" zone to map the flood prone area on the site, and the failure to perform a detailed study, did not comply with the Flood Disaster Protection Act of 1973. Other allegations in the DCA Petition also implicate the delineation of the flood prone areas on the site. See, (5) Ground and Surface Water Quality, below. A FEMA "A" zone is the zone depicting the area determined by FEMA to be flood prone. In this context, FEMA defines a "flood prone" area as an area flooded in a 100-year, 24-hour storm. At the time Polk County reviewed the Crowder project for approval of the roadway and construction drainage plans, FEMA was requiring that a detailed study be performed to delineate the flood prone area. Polk County apparently was not aware of this requirement and was not enforcing it. Nor, apparently, was Crowder's engineer aware of it. In any event, Crowder did not have a detailed study performed to delineate the flood prone area on the site, and the County did not require it. In approximately March, 1992, Polk County received a written communication from FEMA advising of the requirement for a detailed study of the flood prone area in the case of developments like Crowder's. Polk County now requires compliance with this FEMA requirement. Crowder did not rely simply on the FEMA undetailed "A" zone to map the flood prone area on the site. Crowder's engineers used the existing undetailed FEMA maps as a starting point for determining base flood elevations. The engineers digitized the areas which had been designated as flood prone on the FEMA panels. The engineer then overlayed the digitized FEMA map with the on- site wetlands survey of the property, which had been field-staked and field- shot. Topographical field shots of the property which had been conducted throughout the site at one foot intervals were also overlayed on the digitized FEMA map. In addition, the engineer took into consideration mapped wetlands soils and compared flooding conditions which had occurred on adjacent property to assess whether all areas actually prone to flooding had been characterized as flood prone on the FEMA map. The methodology used by the project engineers was based on sound engineering practices. Nonetheless, it does not qualify as a "detailed study" as far as FEMA is concerned. A "detailed study" would include the application of a computer program that would "route" hypothetical flood waters onto and through the property to ascertain flood elevations in different stages of the hypothetical flood. It is not possible to determine how a detailed study would change the delineation of the flood prone area in Crowder's proposal. The total area of flood prone area could either increase or decrease; it could increase in some places and decrease in others. As it is, several of the lots platted in the Crowder development would be entirely within both the FEMA undetailed "A" zone and the flood prone area mapped by Crowder's engineers. Ground Water Recharge. DCA alleges that platting Paradise Country Estates will adversely impact recharge of the Floridan Aquifer, contrary to Policy 9 and 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. In the vicinity of the project site, the Floridan Aquifer comes to within 35 feet approximately of the ground surface. Above the Floridan Aquifer is a shallow aquifer, which rises to within approximately 12 inches of the surface. There is a layer of clastic soils (sand and clay) between the surficial aquifer and the Floridan Aquifer. This confining layer slows the rate of recharge to the Floridan. As a result, the project site is in an area having low, or even very low, to moderate recharge capabilities, at best. USGS Professional Paper 1403-E, which was released in 1990, uses groundwater modelling to quantify recharge rates, instead of using qualitative terms such as "low," or "poor," "moderate" and "high" to describe recharge capabilities. USGS Professional paper 1403-E reports that many areas in the Green Swamp previously labeled as good, moderate or high recharge areas are actually capable of only recharging at rates of 3 to 4 inches per year. The subject property appears to be in the 2 to 3 inch range per year for recharge according to USGS Professional Paper 1403-E. Only three known sample soil borings have been taken on the project site. As a result, the extent of permeability and overall thickness of the confining layer between the surficial and Floridan aquifers is not certain. But there is no reason to believe that there are any karst features or other geologic faults in the area that would allow for direct connections between the surficial and Floridan aquifers. The soil borings that have been taken on the site verify the various geological surveys and studies describing the recharge capabilities in the area. Due to the site's limited capabilities as a recharge area, it is unlikely that the platting of this site will result in any significant reduction in its natural recharge rate. The project is not inconsistent with Policy 9 or 11, Objective III, "Natural Resources," of the LUE, or Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Individual Water Well Use. DCA alleges that the planned use of individual water wells in Crowder's Paradise Country Estates will impact the quantity of the Floridan Aquifer (and the surficial aquifer) contrary to Policy 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. The potentiometric level of the Floridan Aquifer protects the Floridan Aquifer from salt-water intrusion. Significant de-watering of the aquifer caused by large municipal or industrial wells extracting a high volume of water from the aquifer at an intense rate can lower the potentiometric pressure, thus increasing the potential for salt-water intrusion into the aquifer. (Furthermore, the lowered potentiometric pressure creates a hydraulic gradient which encourages surface waters to percolate downward at a faster rate due to the decreased pressure in the Floridan Aquifer. See the preceding sections on Ground Water Recharge and the following section on Ground and Surface Water Quality.) Large municipal, industrial or agricultural wells which exceed 6 inches in diameter must obtain consumptive use permits from the SWFWMD. The Water Management District takes into account what the District determines to be a safe yield per acre when issuing a consumptive use permit. Small, residential wells are not subject to this permitting process as their impacts are much smaller and less intense, and not a concern with regard to their effect on the potentiometric pressure. For this reason, some coastal areas have begun using smaller, individual wells as an alternative to larger municipal wells. The Floridan Aquifer is replenishing itself fast enough for residential wells not to "de-water" or "draw down" the aquifer's supply of ground water. Residential wells do not lower the potentiometric pressure of the Floridan to a significant degree. Nor would they affect the normal supply of ground water, or contribute to salt-water intrusion. Pumping tests performed within two to three miles west of the project site which utilized several residential-size wells support the foregoing conclusions. For these reasons, it is found that the development will not adversely impact the normal supply of ground water and thus will not interfere with the functions of the potentiometric high of the Floridan Aquifer, including its protection against salt-water intrusion. Since the water wells would pump only from the Floridan Aquifer, they would not impact the supply of surface water. In regard to the use of water wells, the project is not inconsistent with Policy 11, Objective III, "Natural Resources," of the LUE, or with Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Ground and Surface Water Quality. DCA alleges that Paradise Country Estates will result in unacceptable contamination of the Floridan Aquifer, the surficial aquifer, and the surface water (particularly the Withlacoochee River) contrary to Policies 9, 10 and 14 of the "Water Resource Objective" of the Conservation Element. Paragraph 20 of the DCA Petition alleges that the use of individual on-site disposal systems (OSDS), or septic tank systems, in violation of Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code), 8/ in particular, will be part of the cause of the unacceptable contamination (other causes being from lawn and garden maintenance and automotive wastes.) On-Site Disposal Systems. Chapter 10D-6, Florida Administrative Code, sets forth requirements for the use of on-site waste disposal, or septic tank, systems in the State of Florida. That chapter, which is administered by the Department of Health and Rehabilitative Services ("HRS") through local health departments, provides construction standards for the installation of on-site waste disposal systems. The septic tank serves as a holding tank designed to separate solids and floatable materials and allows anaerobic digestion of organic materials. The remaining effluent exits the tank into the soil infiltrative process, which is referred to as the drainfield. The drainfield is composed of gravel placed around perforated pipes, which are designed to evenly distribute and release the effluent into soil material where the effluent undergoes aerobic digestion. Eventually, any constituents remaining in the effluent which have not been absorbed by the root zone or otherwise decomposed reach the subsurface waters which are referred to as the surficial water table. Each individual lot owner will be required to obtain a permit from the local health department prior to installing an on-site waste disposal system. Prior to issuing a permit, HRS inspects each site to assess soil limitations and to conduct a percolation test to determine the seasonal high water table for the site. Because the soils on the site are severely limited for filtration purposes and the high water table is only 10 to 12 inches below the surface, individual lot owners will be required to mound their on-site waste disposal systems to overcome these limitations. Although the fill used to mound the systems will be comprised of suitable soils, it is possible that the foreign soils will absorb moisture from the existing soils on this site, a phenomenon referred to as capillary fringe affect. This phenomenon can cause those portions of the fill which come in direct contact with the existing soils on the site to lose their filtration capabilities. Unless the fill becomes saturated from other sources, it is unlikely that capillary fringe affect will render the filtration process ineffective. The effects of capillary fringe affect can be lessened by mixing fill with soils found on the site, a practice undertaken by contractors when installing on-site waste disposal systems. In addition, increasing the amount of fill used to mound the system would decrease the potential affects of this phenomenon. 9/ Floridan Aquifer Water Quality. In some areas of the Green Swamp, the Floridan Aquifer is actually considered a surficial aquifer since no confining layers of soil or clay separate the subsurface water from the Floridan Aquifer. These areas would typically be characterized as areas with high recharge capabilities (or high potential for contamination). However, throughout the project site, a confining layer exists which is composed of clayey sands which have a very low permeability. Therefore, there is relatively little interaction between the surficial aquifer and the Floridan Aquifer on this particular site. For this reason, the use of individual on-site waste disposal systems on this site would pose no significant risk to the water quality of the Floridan Aquifer. Surficial Aquifer and Surface Water Quality.-- As for the surficial aquifer and surface water quality, Chapter 10D-6, Florida Administrative Code, requires on-site waste disposal systems be located at least 75 feet from waterbodies. Normally, and when the systems are operating properly, this assures that adequate filtration and decomposition occurs before wastewater reaches surface waters on or near the site. But, in the case of the Crowder proposal, it is necessary to consider that at least some of the mounded systems will be subjected to flooding and will become saturated. Even based on the analysis by Crowder's engineers, 51 of the lots in Paradise Country Estates are entirely flood prone; there is no place to put an OSDS on those lots that is not flood prone. If a "detailed study" had been done, it is possible that more lots would be entirely within the flood hazard zone. Other lots not entirely within the flood zone may not be able to accommodate an OSDS on the part of the lot not within the flood zone. If the OSDS mound is saturated during flood conditions, the system will fail, and untreated waste, or inadequately treated waste, will be released into the surface flood waters. This waste water will move laterally across the project site. Roots may absorb some nitrates or other organic compounds; 10/ otherwise, the waste water and its constituents will remain in the surface water. Lateral movement across the site generally will be slow, as the site is relatively flat. Some of the waste water and its constituents will get into the surficial aquifer. There are ditches or canals alongside and on the site that will direct the rest of the surface water into Pony Creek and other tributories of the Withlacoochee River, an Outstanding Florida Water approximately three and a half miles to the north. The Department of Environmental Regulation issued a dredge and fill permit for the project's road network's impact on wetlands on the site. But it did not pass on the use of OSDS in the individual lots. It also erroneously referred to the Withlacoochee as a natural Class III, instead of an Outstanding Florida Water. See F.A.C. Rule 17-302.700(9)(i). The Southwest Florida Water Management District (SWFWMD) issued a surface water management permit for the project. In evaluating a permit application, SWFWMD considers surface water quality. But the focus of SWFWMD's inquiry is the pre- and post-development peak flows. Also, when it considers water quality, SWFWMD considers the impact of site alteration on water quality, not the impact of the use of OSDS on the site. In addition, the Crowder project was reviewed under special criteria for low-density rural subdivisions that do not require the submission of as much information. It was not clear from the evidence precisely how SWFMD evaluates water quality under those criteria. For these reasons, based on the evidence, it cannot be said that the Crowder project's OSDS will be meet the minimum standard of being "located to avoid impairment to them or contamination from them during flooding," as required by Section 5-1(6) of Polk County Flood Protection and Surface Water Management Code, or that the project will "protect the normal . . . quality of ground and surface water . . . necessary for the protection of resources of state and regional concern," as required by Policy 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Finally, the project will not "protect or improve existing ground and surface-water quality," as required by Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan. Other Appeal Issues. Except as set forth above, the Crowder development did not violate the 1985 comprehensive plan and Flood Protection and Surface Water Management Code provisions cited in the DCA Petition. Agency Practice - Other Development in the Area. As previously described, Evans Acres, to the west of the Crowder site, was approved by DCA in 1983. (See Finding 10, above.) As approved, it was comprised of 48 lots on approximately 1,290 acres (a density of one unit per 27 acres). The original lots ranged in size from 5 to 60 acres. Unbeknownst to the DCA, individuals apparently have since split their lots and many of the existing lots are 2 to 5 acres in size. A proposed development known as Turkey Creek is located between the project site and Evans Acres. Turkey Creek is comprised of approximately 57 lots on 170 acres with a gross density of 1 unit per 3 acres. The physical characteristics of the Turkey Creek property, including the abundance of wetlands and floodplains, are essentially the same as the proposed project site. DCA appealed Turkey Creek in June of 1992. However, in that case, the County had been approximately two years late in rendering the Turkey Creek development order to the DCA. Meanwhile, the developer incurred development expenses and already had constructed roads and drainage facilities for the development. The developer, the County and DCA executed a settlement agreement which allows the development to proceed according to the original construction plans, but requires homeowners to install dual septic tank systems and have their septic tanks cleaned and inspected every three years. Several other developments, which are in the general vicinity of the project site and have many of the same physical characteristics, including Yearling Trace and Buck Hill, have been appealed by DCA. Yearling Trace is comprised of 108 units on approximately 544 acres. Buck Hill is comprised of 55 units on approximately 214 acres. Those projects were appealed by DCA in June and April, 1992. In some of these cases, the County did not timely render development orders to DCA in a timely manner. In the case of Buck Hill, the DCA had been mailed an unapproved copy of development plans in October, 1990; in early 1992, DCA contacted the County to inquire, as no County-approved development plans ever had been sent to the DCA. In many of these cases, substantial development expenses had been incurred; in some cases, roads and drainage facilities already had been constructed. DCA decided to settle the pending appeals in which the County was late rendering the development order, and in which the developer already had constructed roads and drainage facilities, consistent with the Turkey Creek settlement. In cases where the County was late rendering the development order, but the developer had not already constructed roads and drainage facilities, the DCA determined to settle not only for stipulations to upgrade the OSDS, as in the Turkey Creek settlement, but also for requirements that a "detailed" flood zone study be done, in accordance with the FEMA requirements. Prior to the DCA appeal, Crowder had expended approximately $31,000 in permit fees. In addition, he has incurred development costs, primarily for engineering fees and related services. Through the time of the final hearing, he had spent approximately $99,000 on engineering fees and services. (The evidence was not clear how much had been incurred by the time of the DCA appeal.) However, the County was not late in rendering the Crowder development order, and Crowder has not constructed roads or drainage facilities. In view of the different circumstances in Crowder's case, DCA's prior agency practices do not compel that Crowder's development be treated in the same manner, i.e., be settled on the same terms, as the Turkey Creek and the others. DCA has argued that FLWAC's Final Order in the case of Dept. of Community Affairs v. Narbi International Company, Inc. and Lake County, 14 FALR 3223 (1992), controls this case and requires the Crowder development order to be overturned on appeal. Narbi involved development Green Swamp ACSC, albeit in Lake County. Factually, there are many differences between Narbi and this case. The Narbi development order was a rezoning from agricultural with a residential density of up to one unit per five acres to a residential planned unit development (PUD) zoning with a density of one unit per 1.35 acres. Also, Lake County's comprehensive plan had an "urban containment policy," which DCA equated with its non-rule policy preventing "urban sprawl" or "leap-frog development." Thirdly, in Narbi, it was found that a geologic fault existed on the project site which allowed a direct connection from the surficial aquifer to the Floridan Aquifer. Because of the factual differences, Narbi does not control the outcome of Crowder's case. Conditions for Approval. Based on the testimony of its witnesses, DCA has proposed that, notwithstanding its deficiencies, the Crowder project can be approved if its density is lowered to between one unit per ten acres and one unit per 20 acres. The rationale of DCA's witnesses seems to be that the proposed lower density, in and of itself, would cure at least the most significant of the deficiencies. Since the Crowder development order under review was for approval of particular road and drainage plans, the plans would have to be redrawn at the lower density and resubmitted for approval by the County subject to the final order to be entered in this case. It is not possible for the Commission to approve, on condition of lowered density, the plans that were the subject of the development order in this case.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Florida Land and Water Adjudicatory Commission enter a final order rescinding and denying approval for the development order in this case. RECOMMENDED this 10th day of March, 1993, 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 10th day of March, 1993.
The Issue The issue is whether Petitioner is entitled to an environmental resource permit for a surface water management system and the alteration of a wetland in connection with the construction of two warehouses, paved parking and loading areas, a detention pond, and enhancement of the remainder of the existing wetland. If not otherwise entitled to the permit, an additional issue is whether Petitioner is entitled to the permit through an exemption, waiver, or variance from the standard requirements for mitigation.
Findings Of Fact Background Petitioner Carlos M. Beruff, as Trustee under Florida Land Trust No. 22 dated March 30, 1989 (Petitioner), purchased 85 acres of land in Manatee County for $1.2 million in May 1989. (All acreages are approximate.) The east boundary of the 85-acre parcel consists of about 1700 feet of frontage along U.S. Route 301. One month after the purchase, Petitioner sold 70 of the 85 acres for $1.6 million. In the intervening month, Petitioner incurred no significant expenses for development or marketing, although the development and marketing expertise of Carlos Beruff facilitated the $1.6 million sale. The 70 acres that were sold included the frontage on U.S. Route 301. The 15 acres remaining after the sale comprise two tracts of 9 and 5.88 acres. In these cases, Petitioner seeks an environmental resource permit (ERP) for activities involving the 5.88-acre parcel (Site). The 9-acre parcel occupies the northwest corner of the 85-acre parcel. The Site, which was platted in 1911, is the only noncontiguous land constituting the 85-acre parcel; it is 450 feet south of the remainder of the 85-acre parcel. The sole parcel between the Site and the remainder of the 85- acre parcel was originally owned by Lowe's and is now owned by Cheetah Technologies (Cheetah Parcel). The 5.88-acre Site is subject to a road right-of-way of 0.32 acres in favor of the Cheetah Parcel. Of the remaining 5.56 acres, 4.66 acres are wetland and 0.9 acres are upland. The 0.9 acres of upland are subject to an access easement of 0.42 acres, also in favor of the Cheetah Parcel, so the net available upland acreage is only 0.48 acres. The Cheetah Parcel occupies the northwest corner of U.S. Route 301 and Saunders Road (also known as 63rd Avenue East). The Site is immediately west and south of the Cheetah Parcel and occupies the northeast corner of Saunders Road and 24th Street East (also known as Arlin Road). The Site is about 530 feet west of the intersection of U.S. Route 301 and Saunders Road. U.S. Route 301 is a major arterial, and Saunders Road is at least a major collector road. The Site contains about 600 feet of frontage along Saunders Road and 465 feet of frontage along 24th Street East. The Site is in unincorporated Manatee County roughly midway between downtown Bradenton and downtown Sarasota. Saunders Road crosses a north-south railroad line approximately one-half mile west of the Site and Bowlees Creek about 650 feet west of the railroad track. The 9-acre parcel still owned by Petitioner is about 350 feet north-south by 1250 feet east-west. The western boundary of the 9-acre parcel runs along the east side of the railroad line. Like the other parcels involved in this case, the 9-acre parcel drains into Bowlees Creek. The Site is in an area characterized by industrial land uses, including warehouses, a junkyard, an industrial center, and a bakery. A halfway house for persons recently released from prison is located one-quarter mile to the west of the Site. The Site is zoned HM (heavy manufacturing), which is a limited, and thus valuable, zoning category in Manatee County. Respondent has issued three relatively recent surface water management permits that are relevant to these cases: a 1986 permit for the development of the Cheetah Parcel (Cheetah Permit), a 1988 permit for the widening of Saunders Road from two to four lanes (Saunders Road Permit), and a 1989 permit for the construction of a commercial park north of the Site known as 301 Park of Commerce (301 Permit). Bowlees Creek runs from north to south, emptying into Sarasota Bay across from Longboat Key. Sarasota Bay is an Outstanding Florida Water. Bowlees Creek drains a nine square-mile basin, which is about 21-25 percent developed. The Bowlees Creek basin is an open drainage basin. Due to flooding problems, Manatee County has imposed special limitations upon development within the Bowlees Creek basin. Among these limitations is that the rate of post- development runoff must be less than the rate of pre- development runoff--up to 50 percent less, according to expert witnesses for both sides (Lawrence Weber, Tr. Vol. III, pp. 118-19; and Daryl Flatt, Tr. Vol. IV, p. 230). By stipulation, the Site is at the extreme eastern end of the Bowlees Creek basin. In fact, the Site may have historically drained into Bowlees Creek and will drain into Bowlees Creek after, as described below, the northwest window is added to the surface water management system. In 1993 or 1994, Petitioner began the process of developing the Site following the sale five years earlier of the larger 70-acre parcel. Mr. Beruff has been in the development business for 20 years. His career began in 1980 when Mr. Beruff became an employee for U.S. Homes and Modern Builders; he became self-employed in 1984. Mr. Beruff has developed seven commercial and ten residential developments. Application Process Deciding to pursue warehouse development for the Site, Petitioner initiated the development process by hiring an engineer and environmental consultant. With the assistance of these consultants, Petitioner prepared its application for an ERP. By application dated October 9, 1998, and filed November 13, 1998, Petitioner requested that Respondent issue an individual ERP for the construction on the Site of a surface water management system in connection with the construction of two warehouse buildings, paved parking and loading areas, and a detention pond, as well as the enhancement of the remainder of the existing wetland (Application). The Application states that the total building, parking, and loading areas would be 58,026 square feet and that wetlands constitute 3.37 acres of the 5.88-acre Site. The site plan attached to the Application shows a "wetland preservation & enhancement" area of 1.592 acres at the north end of the Site. To the south, toward Saunders Road, are two buildings with paved parking and loading areas. On the southwest corner is a "stormwater treatment & attenuation" area. After several discussions with Respondent's staff, Petitioner modified the proposed development. In its latest revision, the footprint of the proposed development would occupy 2.834 acres of wetland, leaving 1.826 acres of wetland. On November 13, 1998, Petitioner filed a Petition for Exemption, Waiver or Variance as to Mitigation Requirements, seeking an exemption, waiver, or variance from all laws requiring offsite mitigation or additional onsite mitigation for the portion of the wetland that would be destroyed by the proposed development. Drainage At present, the Site receives runoff from a total of 27 acres. The offsite contributors of runoff are the Cheetah Parcel and a segment of Saunders Road east of 21st Street East. These locations have drained into the Site for hundreds of years. In general, drainage raises two distinct issues: water quality and water quantity. For an open drainage basin, the issue of water quantity expresses itself primarily in runoff discharge rate, although historic basin storage is also an issue. As discussed in the Conclusions of Law, the Respondent's Basis of Review identifies different storm events to which applicants must design different components of surface water management systems. For water quantity, the system may release no more than the permitted discharge rate in the design storm, which is the 25-year, 24-hour storm event. At present, the design storm would produce about eight inches of rain, although the same design storm, due to a different model or modeling assumptions, produced 9.5 inches of rain at the time of the issuance of the permit for the Cheetah Parcel. (The practical effect of this change in the calculation of the design storm is that the quantitative capacity of the surface water management system of the Cheetah Parcel is nearly 20 percent greater than would be required today.) For water quality, the system must capture the first inch of runoff (sometimes only the first half-inch of runoff, depending on the type of system and receiving waterbody). In contrast to the relatively infrequent 25-year storm, approximately 90 percent of the storms in Respondent's jurisdiction produce no more than one inch of runoff. The underlying premise is that the first inch of runoff contains nearly all of the contaminants that will be flushed from impervious surfaces. The Cheetah surface water management system features a wetland and a retention pond along the north property line of the Site. The Cheetah pond and wetland attenuate runoff before allowing it to drain south onto the Site. The Cheetah surface water management system also includes a swale running north along 24th Street East to take runoff eventually to Bowlees Creek. The Saunders Road surface water management system discharging onto the Site consists largely of an underground, offline storage and attenuation system that stores excess runoff, as compared to pre-development rates, in lateral pipes off a weir. Nothing in the record suggests that the surface water management systems authorized by the Cheetah Permit or the Saunders Road Permit fail to provide reasonable assurance that the discharged runoff is of satisfactory water quality. Following their respective permits in 1986 and 1988, respectively, the rates of discharge of runoff from the Cheetah Parcel and Saunders Road were no greater post- development than they had been pre-development. The Cheetah Parcel post-development and pre-development discharge rates were both 10.6 cubic feet per second (cfs). The Saunders Road post-development and pre-development discharge rates were both 32.4 cfs. In issuing the 301 Permit, Respondent authorized the construction of a drainage system that would take runoff north along 24th Street East and then west, eventually emptying into Bowlees Creek. Conforming to the previous drainage system, the new system replaced an open ditch with underground stormwater pipes. Of particular relevance to the Site, two prominent features of the system authorized by the 301 Permit were windows in the vicinity of the southwest and northwest corners of the Site (Southwest Window and Northwest Window). A window is an opening in the wall of a hardened structure whose purpose includes drainage. The opening is constructed at a certain elevation and a certain size to allow specified volumes or rates of water to pass into the structure and then offsite. The 301 Permit authorized the construction of a swale along the southwest corner of the Site to direct runoff discharging from the Saunders Road system into the Southwest Window. This swale has been construed. However, several problems have precluded the construction of the Southwest Window, probably permanently. The most serious problem, from an engineering perspective, is the failure to lay the stormwater pipe along 24th Street East at the proper depth. The stormwater pipe was erroneously installed at an elevation of 15.32 feet National Geodetic Vertical Datum (NGVD), and the Southwest Window was to have been cut at a control elevation of 14.75 feet NGVD. The discharge elevation of the Saunders Road outlet precludes raising the control elevation of the Southwest Window sufficiently to allow gravity drainage into the stormwater pipe. Exacerbating the discrepancy among the as-built elevations of the three structures is what appears to be a design problem belatedly recognized by Respondent. Respondent is justifiably concerned that the Southwest Window, at a control elevation of 14.75 feet NGVD, would draw down the water elevation of the Site's wetland, which is at a wet season elevation of 16.5 feet NGVD (now actually 17 feet NGVD, possibly due to the absence of the Southwest Window). A third problem with the Southwest Window is that the southwest corner of the Site was not historically a point of discharge, so the Southwest Window would deprive the Site's wetland of runoff. Fortunately, neither the Southwest nor the Northwest Window is essential for the proper operation of the surface water management system of 301 Park of Commerce, which largely depends on a series of lakes for treatment and attenuation. The Northwest Window was to be at elevation 16.5 feet NGVD, and its construction would provide needed drainage for the Site. In general, the Northwest Window does not raise the same concerns as does the Southwest Window. The Northwest Window is in the vicinity of the historic point of discharge for the Site and replaces a ditch permitted for the Cheetah Parcel to take runoff north along 24th Street East. The Northwest Window would also alleviate a standing-water problem at the northwest corner of the Site. However, Manatee County, which controls the right- of-way on which the Northwest Window is located and is responsible for its construction and maintenance, has discovered that it lacks a sufficient property interest to access the Northwest Window. The County has since initiated the process by which it can obtain the necessary interest, and, once completed, the County will cut the Northwest Window into the existing structure. Due to the role of the Northwest Window in draining the runoff in the area, including the Site, the Application reincorporates the Northwest Window, as it should have been constructed pursuant to the 301 Permit. Although the Cheetah and Saunders Road permits resulted in greater runoff volume entering the Site, more importantly to area drainage, these permits did not result in greater runoff rates and or in a deterioration in runoff water quality. Likewise, the failure to construct the Southwest Window and Northwest Window is not especially relevant to area drainage, nor is the likely inability ever to construct the Southwest Window. Far more important to area drainage is the fact that Petitioner proposes that the Site, post-development, would produce a runoff rate of 10.6 cfs, as compared to a pre-development runoff rate of 7 cfs. A serious adverse impact to area drainage, the proposed activity increases the runoff rate by 50 percent in a floodprone, 80-percent builtout basin--a basin of such sensitivity that Manatee County is imposing a post-development requirement of substantially reduced runoff rates. The cumulative impacts of the proposed development, together with existing developments, would be to cause substantial flooding of the Bowlees Creek basin. Petitioner's expert attempted to show that the runoff from the Site, which is at the extreme eastern end of the Bowlees Creek basin, would be delayed sufficiently so as not to exacerbate flooding. Respondent's expert thoroughly discredited this testimony due, among other things, to its reliance upon obsolete data and an unrealistic limitation upon the assumption of the direction of travel of storms. Similarly, Petitioner failed to prove that the authorized discharge rate for the 301 Permit is 42 cfs. This assertion is most succinctly, though not exclusively, rebutted by the fact that the 42-inch pipe can only accommodate 18 cfs. Even if the 42-inch pipe could accommodate a substantially greater runoff rate, Petitioner's expert would have erroneously inferred a permitted discharge rate from this increased capacity without negating the possibility that other structures in the 301 surface water management system effectively reduced the rate or that oversized structures existed to accommodate higher runoff rates in storms greater than the design storm. In addition to increasing the runoff rate by 50 percent, Petitioner's proposal would also reduce the historic basin storage by over 40 percent. Displaced basin storage moves downstream, increasing flood levels from fixed storm events. At present, the Site provides 8.68 acre-feet of historic basin storage. The Application proposes to replace this storage with storage in the wetland and retention pond totaling only 4.9 acre-feet. The loss of 3.8 acre-feet of basin storage means that this additional volume of water would, post-development, travel down Bowlees Creek. A final drainage deficiency in Petitioner's proposal arises out of a berm's proposed outside of the Northwest Window. A one-foot bust in the survey of Petitioner's expert would have resulted in this berm preventing runoff from entering the Site from the Cheetah Parcel, as runoff presently does. Respondent's expert suggested several possible alternatives that might result in a permittable project with respect to post-development runoff rates (the record is silent as to the effect of these alternatives upon historic basin storage, although it would seem that they would add storage). Reducing the area of destroyed wetlands to one acre would probably reduce the excess of post-development runoff rate to 1-2 cfs. Petitioner could then obtain offsetting attenuation through a variety of means, such as by obtaining an easement to use the wetland on the Cheetah Parcel, constructing an attenuation pond on the 9-acre parcel, or constructing underground vaults in the filled area of the wetland on the Site. Wetlands Except for the road right-of-way, the Site is undeveloped and forested. The presence of 25-year-old red maples militates against attributing the transition from an herbaceous to a forested wetland to the failure to install the Northwest and Southwest windows. More likely, this transition to the sub-climax species of red maple and willow (in the absence of a cypress source) is due to the repression of fire on the Site. Experts for the opposing sides differed sharply in their biological assessments of the wetland. Petitioner's expert described a stressed wetland whose impenetrable thicket provided habitat only to a lone rat and swarm of mosquitoes. Respondent's expert described a robust wetland featuring a luxuriant overstory of red maple and Carolina willow; an rich understory of ferns, and diverse wildlife ranging from birds in the air (direct evidence); fish, snails, and tadpoles in a small pond (direct evidence); and squirrel and opossum (indirect evidence) scampering (indirect evidence) among the buttonbush, elderberry, and wax myrtle (direct evidence). Undoubtedly, the wetland has been stressed; approximately 30 percent of the wetland vegetation is Brazilian pepper, which is a nuisance exotic. However, the wetland is well hydrated. Issuance of the Cheetah Permit was predicated, in part, upon the rehydration of the wetland on the Site. With the issuance of the Cheetah Permit and especially the Saunders Road Permit, the quality of water entering the wetland has improved by a considerable amount. As already noted, added volumes of runoff are entering the wetland since the issuance of these two permits, although post-development runoff rates are the same as pre-development runoff rates. On balance, the wetland is functioning well in providing habitat and natural drainage functions. Giving due weight to the current condition of the wetland, the enhancement offered by Petitioner does not approach offsetting the loss of wetland area. In return for destroying 2.83 acres of the wetland, Petitioner proposed the enhancement of the remaining 1.83 acres by removing exotic species to no more than 10 percent of the total vegetation. The mitigation is plainly insufficient because of the level of functioning of the entire wetland at present. Additionally, Petitioner has failed to demonstrate that the Brazilian pepper, which is the major nuisance exotic occupying the Site, is evenly distributed; to the contrary, it is present mostly outside the wetland, along a berm just outside of the wetland. The lack of seedlings and old specimens suggests that the Brazilian pepper population may not be stable and may itself be stressed. Petitioner's failure to show that the remaining wetland area has more than 10 percent infestation or is likely to suffer additional infestation further undermines the effectiveness of the proposed mitigation. Respondent has never issued an ERP for a proposed activity involving the alteration of wetlands when the enhancement mitigation ratio is as low as .65:1, as Petitioner proposes. In general, Respondent requires higher mitigation ratios when proposals involve wetlands enhancement, rather than wetlands creation, because the wetlands to be enhanced are already functioning--in these cases, at a relatively high level. Although Petitioner has been unwilling to consider such alternatives, numerous alternatives exist for offsite mitigation or mitigation banking, if insufficient area exists for adequate onsite mitigation. Lastly, Petitioner devoted considerable effort at hearing to portraying Respondent's handling of the Application as flawed and unfair. However, the evidence does not support these assertions. Most strikingly, Respondent's staff treated the drainage windows inconsistently, to the benefit of Petitioner. They treated the Northwest Window as installed for the purpose of calculating the pre-development runoff discharge rate to Bowlees Creek. Until the Northwest Window is installed, the actual rate is even lower. This approach is justifiable because the Northwest Window will be installed at some point. On the other hand, Respondent's staff ignored the higher wetland elevation on the Site, presumably resulting from the absence of the Southwest Window. However, this approach, which benefits Petitioner in calculating wetland drawdown effects, is unjustifiable because the Southwest Window probably will never be installed. Petitioner's specific complaints of unfair treatment are unfounded. For example, Petitioner suggested that Respondent credited Lowe's with wetland acreage for the littoral shelf of its wetland, but did not do so with the wetland on the Site. However, Petitioner produced no evidence of similar slopes between the two shelves, without which comparability of biological function is impossible. Additionally, Petitioner ignored the possibility that, in the intervening 14 years, Respondent may have refined its approach to wetland mitigation. Although occurring at hearing, rather than in the application-review process, Respondent's willingness to enter into the stipulation that the Site presently drains into Bowlees Creek, despite recent data stating otherwise, was eminently fair to Petitioner. Absent this stipulation, Respondent would have been left with the formidable prospect of providing reasonable assurance concerning drainage into the floodprone Bowlees Creek when the post-development rate was 10.6 cfs and the pre-development rate was 0 cfs.
Recommendation Based on the foregoing, it is RECOMMENDED that Respondent deny Petitioner's application for an environmental resource permit and for an exemption, variance, or waiver.

Whether flood protection would be inadequate or septic tanks unsuitable or whether the public health and safety would be compromised or the ultimate purchasers be deprived of usage of the property due to inundation in violation of Chapter 373, Florida Statutes (1981), or Rule 40E-4.301(1), Florida Administrative Code?
Findings Of Fact Ms. Williamson and Messrs. Leggett and Collins hold in fee simple a triangular 117.24-acre parcel in Okeechobee County as tenants in common under a warranty deed executed in their favor by one W. C. Sherman. They propose to develop the property as a trailer park (complete with airstrip) large enough to accommodate 109 trailers. To this end, soil would be dug up from the center of the property and used to raise the elevation of the surrounding land above the 100-year floodplain. (T. 47) The applicants have a dredging permit from the Department of Environmental Regulation authorizing them to excavate 629,889 cubic yards. They are proposing to dig to a depth of 76 feet below ground. This would create an 18-acre body of water ("Poe's Lake") which would overflow a V-notched weir into a county canal. The county canal would take the water to C- 38, one of the large canals to which the Kissimmee River has been relegated, at a point about 18 miles upstream from Lake Okeechobee. Runoff would wash over residential lots and roadways; the site would be graded to assure drainage into Poe's Lake. The minimum road crest elevation would be 30 feet NGVD ("[a]round twenty-nine feet" T.52), as compared to the control elevation for surface waters of 28.5 feet NGVD. WATER QUALITY The developers plan septic tanks for wastewater treatment. At the close of all the evidence, counsel for the applicants stated that sanitary sewers could be installed instead. Respondents' Proposed Recommended Order, p. With all the housing units in use, at least 10,900 gallons of effluent would seep into the ground from the tanks daily. There would be some evapotranspiration, but all the chemicals dissolved in the effluent would eventually end up in the groundwater. During the dry season, septic tank effluent would cause mounding of the groundwater and some groundwater movement toward, and eventual seepage into, Poe's Lake. The eventual result would be eutrophication and the growth of algae or macrophytes on the surface of Poe's Lake. This would cause dissolved oxygen violations in Poe's Lake. Discharges from the lake would inevitably occur, aggravating the situation in C-38, which already experiences dissolved oxygen levels below 5.0 milligrams per liter in the rainy summer months. Some fraction of the nutrients in the effluent from the septic tanks would ultimately reach Lake Okeechobee itself. The sheer depth of the excavation would create another water quality problem. Under the anaerobic conditions that would obtain at the bottom of Poe's Lake, bacteria acting on naturally occurring sulfates would produce hydrogen sulfide, ammonia and various other reduced organic nitrogen compounds. These substances are toxic to human beings and would, in some indeterminate quantity, enter the groundwater from Poe's Lake. This would affect the taste and perhaps the potability of water from any well nearby. It would be "possible to design a better system where there would be nutrient removal and a greatly reduced probability of violation of the dissolved oxygen criterion and obviation of the potential for ground water contamination." (T. 200) Installation of a baffle on the weir would serve to prevent buoyant debris from entering surface waters of the state. BASIS OF REVIEW Official recognition was taken of the "Basis of Review for Surface Water Management Permit Applications Within the South Florid Water Management District," parts of which all parties agree pertain in the present proceedings. Among the criteria stated in this document are: 3.1.3 Waste and Wastewater Service - Potable water and wastewater facilities must be identified. The Applicant for a Surface Water Management Permit must provide information on how these services are to be provided. If wastewater disposal is accomplished on-site, additional information will normally be requested regarding separation of waste and storm systems. 3.2.1.4 Flood protection - Building floors shall be above the 100 year flood elevations, as determined from the most appropriate information, including Federal Flood Insurance Rate Maps. Both tidal flooding and the 100 year, 3 day storm event shall be considered in determining elevations. b. Commercial and industrial projects to be subdivided for sale are required to have installed by the permittee, as a minimum, the required water quality system for one inch of runoff detention or one half inch of runoff retention from the total developed site. State standards - Projects shall be designed so that discharges will meet State water quality standards, as set forth in Chapter 17-3, Retention/detention criteria - 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 runoff from the developed project, or the total runoff from a 3-year, 1-hour rainfall event, whichever is greater. Dry detention volume shall be provided equal to 75 percent of the above amounts computed for wet detention. Retention volume shall be provided equal to 50 percent of the above amounts computed for wet detention. 3.2.4.1 Discharge structures should include gratings for safety and maintenance purposes. The use of trash collection screens is desirable. Discharge structures shall include a "baffle" system to encourage discharge from the center of the water column rather than the top or bottom. 3.2.4.4.2 b. Control elevations should be no higher than 2 feet below the minimum road centerline elevation in the area served by the control device in order to protect the road subgrade. Simply detaining runoff before discharging it offsite will not insure that the water quality standards set forth in Chapter 17-3 will be met. Whether the standards are met depends on, among other things, the composition of the runoff. FWF'S INTEREST Among the purposes of the FWF, as stated in its charter, Shall be to further advance the cause of conservation in environmental protection, to perpetuate and conserve fish and wildlife, oil, water, clean air, other resources of the State and so manage the use of all natural resources, that this generation and posterity will receive the maximum benefit from the same. (T. 248-9) Four or five thousand Floridians belong to FWF. FWF members "make use" (T. 250) of the waters of Lake Okeechobee, the Kissimmee River and specifically of the waters in C-38. PROPOSED FINDINGS CONSIDERED The applicants and FWF filed post hearing memoranda and proposed recommended orders including proposed findings of fact which have been considered in preparation of the foregoing findings of fact. They have been adopted, in substance, for the most part. To the extent they have been rejected, they have been deemed unsupported by the weight of the evidence, immaterial, cumulative or subordinate.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That SFWMD deny the pending application for surface water management permit.

Findings Of Fact The CLDD was established pursuant to Chapter 298, Florida Statutes, on August 4, 1967. Its purpose was to "reclaim" or render the land within its boundaries usable for agricultural purposes. The land comprising the CLDD consists of approximately 3,500 acres in Lee County, mostly planted in citrus trees. Pursuant to the requirements of Chapter 298, Florida Statutes, a "Plan of Reclamation" was prepared by consulting engineers for the CLDD's Board of Supervisors in August, 1967. That plan contains provisions for reclaiming lands within the CLDD's boundaries and for managing and controlling surface water within CLDD. The method of water control outlined in the 1967 reclamation plan included a dike and ditch system around the boundaries of CLDD with a series of interior canals to carry excess water away from the citrus trees. The land in the north part of he CLDD is higher than the south and water generally, naturally flows from north to south. The interior canals were designed to carry water in accordance with existing contours of the land and eventually discharge excess surface water to the rim ditches on the north and east sides of Spoil Area "M," which is south of the CLDD and which was then owned by the C&SFFCD, the predecessor agency to SFWMD. The system of drainage delineated in that 1967 plan, inaugurated pursuant to Chapter 298, Florida Statutes, was put into effect substantially as described therein. CLDD's 1967 plan was altered somewhat because of an agreement entered into on September 30, 1971, between the CLDD and neighboring landowner Kenneth Daniels. Pursuant to that agreement, the two parties agreed to extend the dike on the west side of the CLDD property and construct a ditch from a point 50 feet north of the northwest corner of the Petitioner Mellor's property, which new ditch was to run southwest across the Daniels' property and connect with Spanish Creek. That ditch or canal would thus connect the western rim ditch of the SFWMD's Spoil Area "M" with Spanish Creek and have the result that surface waters could be discharged from CLDD lands through the western rim ditch of Spoil Area "M" thence through the "Daniels' Ditch" finally discharging into the lower reaches of Spanish Creek. (see Exhibits 1 and 11) Because the western side or western rim canal of the SFWMD's Spoil Area "M" had not been used under the original plan of reclamation approved by the C&SFFCD, CLDD sought permission from C&SFFCD to use this western rim canal for the purpose stated pursuant to the agreement with Daniels. Thus, CLDD's proposed use of the rim canal of Spoil Area "M" would be confined to the western, northern and eastern perimeter canals and not the southern boundary canal. All affected landowners, Kenneth Daniels as well a Jake and Lilly Lee, agreed to those proposed installations and uses. The resulting agreement between CLDD and C&SFFCD was entered into on October 12, 1972, and describes the flood control District land to be used by CLDD as a 100 foot wide strip running along the west, north and east sides of Spoil Area "M," also know as "Aspic." This 100 foot wide strip of land running thusly is co-extensive with the rim ditch of Spoil Area "M." The CLDD was mandated by this agreement to install 72- inch pipes in the rim ditch at the southwest corner of the spoil area, just north of the Mellor property, giving a point of discharge from the western rim ditch into the Daniels' Ditch with similar pipes connecting that Daniels' Ditch with Spanish Creek, such that the canal between these two points could carry water from the west rim ditch to Spanish Creek. The easement incorporated in this agreement was to last for five years with an option for a five-year renewal, which option was exercised. At the end of this 10-year period, SFWMD, successor to C&SFFCD, notified CLDD that because its statutory authority had since changed, the easement could not be renewed and that CLDD would have to seek the subject permit so as to be authorized to use works and lands of the District. The requirements to be met by an applicant for a right-of-way permit such as this one are set out in Rule 40E-6.301, Florida Administrative Code, and SFWMD's permitting information manual, Vol. V, Criteria Manual for Use of Works of the District, July, 1981, which is incorporated by reference in that rule. In that connection, the permit at issue, if granted, would not cause an interference with the "works" of the District, that is dikes, ditches, flood control structures arid drainage structures because it would merely renew the pre-existing authorized use. The permit will not be inconsistent with an comprehensive water use plan developed by the District. Further, the permit applicant owns or leases the land adjacent to the portion of the "works of the District" involved herein that is the east, north and west rim ditches of Spoil Area "M," the Daniels' Ditch and the pipes at either end of it coupled with the water control structures at the southeast corner and southwest corners of Spoil Area "M," which control water entering the south rim ditch. CLDD has a surface water management permit, issued in August, 1980, which is a prerequisite to the granting of the subject right-of-way permit. It remains in full force and effect. That surface water management permit authorizes "operation of a water management system serving 3,642 acres of agricultural lands by a network of canals and control structures, with a perimeter dike and canal discharging into Cypress Creek." The "surface permit" authorized the system of drainage and discharge in existence at the time of its issuance, May 8, 1980. The system of drainage, at the day of the hearing, consisted of the same basic water flow and discharge pattern that existed for approximately 10 years, and this permit would allow that to be continued, thus, there will not be any additional effect on environmentally sensitive lands occasioned by an issuance of the subject right-of-way permit. The surface water management permit, by its terms, refers initially to the operation of a water management system" . . . discharging into Cypress Creek." The reference to "Cypress Creek" was an administrative error. The express language on the face of the permit authorization incorporates by reference the application, including all plans and specifications attached thereto, as addressed by the staff report, and those materials, including the staff report, are a part of the permit. The complete permit, including all those documents incorporated by reference, makes it clear that the authorization of the surface water management permit was that the system of drainage in existence at the time of permit issuance (1980) was that which was being approved, and that included discharge to Spanish Creek and not Cypress Creek. Discharge of water to Cypress Creek as an alternative was never recommended or authorized by that surface water management permit. This is clearly the intent expressed in the permit in view of the language contained in a special condition of that surface water management permit imposed by the SFWMD as a condition for issuance which stated as follows: Within 45 days of the issuance of this permit the permittee shall submit for staff approval a proposal and schedule for the elimination of the adverse impacts being created by the operation of the permittee's water management system, which can be legally and physically accomplished by the permittee. Adverse impacts are considered herein to be reduced flows to Spanish Creek and increased flows to Cypress Creek. Thus, it is obvious that the authorization of the surface water management permit was designed to provide for discharge into Spanish Creek and to enhance the flows to Spanish Creek pursuant to a required proposal which the permittee submitted to SFWMD. Thus, the right-of-way permit applied for herein is consistent with the valid surface water management permit held by the permit applicant in this proceeding. Petitioners William H. and Patricia H. Mellor are co-owners of parcels of property lying some distance south of Spoil Area "4" in the vicinity of the Caloosahatchee River. This property does not abut the spoil area at any point. Spanish Creek does cross their property several thousand feet south of the south boundary of the spoil area. In the past, particularly in 1982, water flowing from the south rim ditch of the spoil area through a break in the dike of that south rim ditch, has flowed through a ditch known as Dry Creek in a generally southerly direction under S.R. 78 and has washed out an access road constructed by William Mellor which leads from Highway 78 to his property. He had this washout repaired at his own expense in 1982. The washout was caused by water from CLDD flowing into the south rim canal of Spoil Area "M," that is, the ditch that traverses (and defines) the southerly boundary of the spoil area. Mr. Mellor admitted, however, that SFWMD had at least partially plugged the opening in the south rim ditch which had allowed flow down the Dry Creek ditch and wash out his road. If closed water control structures are maintained at the southwest and southeast corners of the spoil area ditches, then no water could flow into the south rim canal and no such injury could again be caused. Petitioner's Jim English and Patricia Mellor are co-owners of a 45- acre parcel of land located in the southwest corner of Spoil Area "M." The five acres forming the extreme southwest corner of the spoil area do not belong to these Petitioners, but are owned by one Lynwood Brown, who is not a party to this proceeding. The English/Mellor property forms a part of the spoil area, but does not adjoin or constitute any part of the spoil area which is sought to be used by CLDD through the proposed right-of-way use permit (as clarified by CLDD's stipulation). The south rim ditch, either part of, or adjoined by their property, has been used for water storage in the past (they maintain illegally) 1/ Mr. Tom Pancoast has observed Spanish Creek frequently over a nine- year period starting in approximately 1973. He has often used those waters during that period for fishing. During the early years of his use and observation of Spanish Creek, the water flowed out of Spanish Creek into the Caloosahatchee River. Beginning in about 1976, the water appeared to be flowing in the opposite direction, from the river into Spanish Creek. Contemporaneous with this hydrologic change, the creek has become increasingly characterized by siltation and hyacinth growth. Mr. William Mellor owns property along the course of Spanish Creek. He has used the stream for recreational purposes, picnicking where the stream traverses his property. In recent years there has occurred a marked increase in the growth or profusion of aquatic plants of unidentified types in the creek, reduced clarity and reduced flows or volumes of water in the creek. Witness English has made a similar observation. Witness James English has a substantial degree of training by formal education and experience in water management and drainage practices and methods, particularly as they relate to citrus grove development and management in southwest Florida. Mr. English has observed Spanish Creek regularly for most of his life, including the region of its headwaters in the "Cow Prairie Cypress," a remnant wetland cypress strand lying within the CLDD immediately north of Soil Area "M." The chief adverse impact of the CLDD water management system is reduced flow to Spanish Creek, especially its upper reaches since the advent of the "Daniels' Ditch" as a drainage route and discharge point into lower Spanish Creek. However, the only special condition on the issuance of the surface water management permit approving CLDD's extant water management system was the requirement that CLDD should submit a plan for eliminating that adverse effect, which it did (as Petitioner English admits). Beyond the submission of such a plan, no concrete action designed to restore historic flows to Spanish Creek has yet begun, however. The restoration of historic flows, adequate in volume and quality, to the entire creek system would require discharging water from CLDD's system to the Cow Prairie Cypress area at the headwaters of the creek rather than substantially further downstream at the present Daniels' Ditch site. The Petitioners' complaints (aside from the issue of adequacy of flows in Spanish Creek), although meritorious, are, because of stipulations asserted by CLDD during the course of this proceeding, now rendered moot. CLDD stipulated that it only seeks a permit to use the west, north and eastern spoil area ditches. It does not seek and stipulated that it will not use, at any time, the south rim ditch and will maintain water control structures so to block water from entering that ditch. This will alleviate the problem of potential storage of water on Petitioners English and Patricia Mellor's property and the erosion problem on Petitioners William and Patricia Mellor's property south of the spoil area. It was thus established that the issuance of the right-of-way permit will not cause the injuries these Petitioners have suffered in the past because of use of the south rim ditch for water drainage and storage.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence in the record and the candor and demeanor of the witnesses, it is, therefore RECOMMENDED: That the South Florida Water Management District grant the County Line Drainage District's application for a permit for utilization of works and lands of the District. Subject to the following special condition: Issuance of this right-of-way permit does not relieve the Respondent CLDD from the responsibility of complying with special condition number 1 of the surface water management permit number 36-00184-S. Respondent CLDD shall, within 30 days of date of permitting, submit a design to the satisfaction of the SFWMD staff which will prevent the ability of CLDD to discharge to the southern rim ditch, described above. DONE and ENTERED this 29th day of September, 1983, in Tallahassee, Florida. P. MICHAEL RUFF Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 29th day of September, 1983.
The Issue Whether the application of Telegraph Cypress Water Management District to modify an existing surface water management system permit should be granted.
Findings Of Fact The South Florida Water Management District (District) is a public corporation in the State of Florida existing pursuant to Chapter 25270, Laws of Florida, 1949, and operating pursuant to Chapter 373, Florida Statutes, and Chapter 40E, Florida Administrative Code. The District is a multipurpose water management agency with principal offices in West Palm Beach, Florida. Telegraph Cypress Water Management District (TCWMD) is a water control district organized pursuant to Chapter 298, Florida Statutes. Agricultural operations have been conducted within the TCWMD for more than 30 years by the landowner, Babcock Florida Company. The TCWMD is the permittee of record. James D. English, Jr., owns, along with other members of his family, an orange grove and pasture in Lee County, Florida. The English family has owned the property for approximately 120 years. On November 10, 1992, James D. English, Jr., and the Panacea Timber Company filed a petition for formal administrative hearing challenging the District's intent to issue SWM Permit Modification No. 08-00004-S. Cypress Creek Partnership is a Florida General Partnership of which James D. English, Jr., is a principal. The partnership engages in agricultural activities in Lee County, Florida. The Alva Cemetery, Inc., is a Florida not-for-profit corporation which owns and manages a cemetery facility in Lee County Florida. The cemetery has been in active use for approximately 120 years. In recent years, Alva Cemetery has experienced occasions of excess water encroaching onto the cemetery property. On November 12, 1992, Alva Cemetery, Inc., filed a petition for administrative hearing challenging the District's intent to issue SWM Permit Modification No. 08-00004-S. James D. English, Jr., Cypress Creek Partnership and Alva Cemetery, Inc., are herein referred to as Petitioners. The TCWMD and the Petitioner English share a common property boundary. The Alva Cemetery is surrounded by the English property. All lands involved in this matter historically drain towards the Caloosahatchee River. The TCWMD includes approximately 89,120 acres of land located in Charlotte and Lee Counties, Florida. The land uses within the TCWMD include agricultural, cattle, and timber operations. Generally, the fields have been leased to third party farmers who use the field for several years. When the fields are not actively farmed, they are returned to a fallow state and used as pasture land until fertility is restored at which time they are reactivated for farming. Active farms fields are generally surrounded by a perimeter ditch and dike system. Pumps may be used to water and de-water the fields. When the field is returned to a fallow state, the ditch and dike system are not maintained and become less prominent either by action of weather or by intent. Pumps are not present. All of the TCWMD lies generally north to northwest of the property owned by the Petitioners. Surface waters flow onto the Petitioners' lands from the north. The Telegraph-Cypress system is unique and is the largest of its kind in South Florida Water Management District jurisdiction. The TCWMD system includes storage/detention facilities, control structures, pumping stations and an extensive network of internal canals. There are nine separate water management basins within the TCWMD. The Petitioners asserted that the water management basins identified by the District and the TCWMD are incorrect. The greater weight of the evidence establishes that the District's identification and delineation of the nine basins is based on historical hydrologic characteristics of the TCWMD and is a reasonable determination of basin boundaries. The land encompassed by the instant application for permit modification includes three of the nine basins and encompasses approximately 51,400 acres of the TCWMD. Surface water discharge from the relevant farm fields flows via the internal canal network and sheet flow to the three common detention basins: Telegraph Swamp, North Telegraph Swamp ("Telegraph North") and Curry Lake. The Telegraph North basin lies to the north of and discharges into the Telegraph Swamp basin and includes 13,799 acres of which 4,094 acres are farm fields. The drainage into the Curry Lake basin does not impact either the Telegraph North or Telegraph Swamp basins or the Petitioners' properties. The evidence establishes that as to the Telegraph North and Curry Lake drainage basins, the permit modification meets applicable permitting criteria. There is no credible evidence to the contrary. Telegraph Swamp is the largest of the three relevant detention systems. The Telegraph Swamp basin includes a total of 32,707 acres of which 4,381 acres are farm fields. Telegraph Swamp is a 4,390-acre wetland vegetated by cypress trees and sawgrass, with a base of muck soils, humus, topsoil, leaf litter and other organic material. Located at the south end of Telegraph Swamp are surface water management control structures (the Big Island Dike) built in 1975 and permitted in the original 1980 permit. The structures include three broad-crested weirs and one flash-board weir. Telegraph Swamp has been compared to a "sponge" capable of absorbing vast quantities of surface water discharges within the TCWMD before the control structures at the south end of the swamp are over-topped. Water discharged from the control structures flows through canals and creeks to the Caloosahatchee River. During storm events water is discharged over the control structures and into a swamp area south of Big Island Dike. From there, the water flows southerly, into Telegraph Creek, Big Island Canal and Cypress Creek and then into the Caloosahatchee. The Petitioners expressed concern that TCWMD could inappropriately discharge water from the control gates in the Telegraph Swamp weir. Based on evidence admitted at the hearing, the permit modification should include the following special condition: Discharge structures in the Telegraph Swamp basin shall remain fixed so that discharge cannot be made below the control elevations, except that structure gates and weirs may only be removed during emergency conditions upon notification to and consent by the District's Fort Myers Service Center regulatory area manager or designee. The Basis of Review for Surface Water Management Permit Applications within the South Florida Water Management District--September 1989, incorporated into Chapter 40E, Florida Administrative Code, provides the applicable water quantity permitting criteria relevant to this proceeding. The Petitioners assert that the control gates are required to be locked in accordance with Basis of Review section 3.2.4.1.b, which states: Discharge structures shall be fixed so that discharge cannot be made below the control elevation, except that emergency devices may be installed with secure locking devices. Either the District or an acceptable govern- mental agency will keep the keys for any such devices. The Petitioners are correct. The rule requires secure locking devices. Such condition should be added to the permit The keys may remain with the TCWMD as "an acceptable governmental agency." In 1980, the District issued Surface Water Management Permit No. 08- 00004-S for the TCWMD to operate an existing surface water management system for an existing agricultural operation. The 1980 permit specifically authorizes "[o]peration of a water management system serving 89,120 acres of agricultural lands by a vast network of internal drainage and irrigation canals, a major dike, a major canal and 4 water control structures discharging via small tributary creeks and sloughs into the Caloosahatchee River." Although the permit has been subsequently modified, the authorization to operate the system has not been amended. While District enforcement staff have occasionally noted "performance deficiencies" on the TCWMD property, there have been no permit violations by the permittee. Deficiencies which have been called to the TCWMD's attention have been resolved. Special condition number five to the 1980 permit provides that "[d]ischarges of water onto adjacent lands may be continued to the extent that increased problems are not caused by such discharges." The Petitioners assert that the District has failed to acknowledge that water discharged from the Telegraph Cypress system flows into the Cypress Creek canal and has failed to consider the impact on the Cypress Creek receiving body. However in the staff report to the 1980 permit states as follows: The Telegraph Cypress basin has three major drainage outlets. These are Trout Creek on the west, Telegraph Creek in the center and Cypress Creek to the east. There is a fourth outlet in the northeastern corner of the property known as Jack's Branch, however, this outlet is small compared to the three major ones. Much of Telegraph's southeastern area was previously drained by Spanish Creek and County Line Canal. This historical drainage pattern was blocked when a company which is presently known as Golden Grove constructed a dike across their northern boundary. This dike causes increased flow in a westerly direction around the west end of the dike, thence southerly towards Cypress Creek. This increased flow has caused excess water problems to property owners downstream. In addition, the dike has blocked virtually all flow to Spanish Creek. The evidence fails to establish that, as asserted by the Petitioners, the District has failed to acknowledge the discharge of water to Cypress Creek or to consider the condition of the Cypress Creek receiving body. In the instant case, the condition of the Cypress Creek receiving body was not re- addressed because the permit modification being sought will cause no additional adverse impacts on existing conditions. Although not individually numbered and identified in the original 1980 permit, the evidence establishes that in 1980, all of the farm fields which are subject to this permit modification application were in existence. The applicant seeks no new water control structures. Other than that required to reactivate fallow farm fields, there is no new construction proposed in the instant application. The Petitioners assert that the instant permit modification application will result in construction of new farm fields. The evidence is contrary to the assertion. Proposed permit special condition No. 10 states that the permit does not include the construction of any new farm fields. The farm fields covered in the staff report would be permitted for reactivation from a fallow state without further permitting activity in the future, and without individual retention for each farm field. The modifications to the original 1980 permit have increased the total farm land area. There is no evidence that, except as specifically permitted and approved by the District, there has been alteration of historical discharge rates or routes. There has been considerable confusion regarding the permitting status of the operations as farm fields have been reactivated. Such reactivation entails grading and leveling fields, reconstruction of ditches and dikes and installation of pumping equipment. In order to provide for standardization in farm field reactivation, and to better monitor such activities, the District requested that the TCWMD seek to modify the existing permit. On February 8, 1991, the TCWMD submitted an application to modify the existing permit for the purpose of reactivating the existing farm fields located within the Telegraph North, Telegraph Swamp, and Curry Lake drainage basins. The proposed SWM permit modification authorizes the continued use of the previously permitted surface water management system for existing active and fallow farm fields and allows the reactivation of currently fallow farm fields without further permit modification by the District. Proposed SWM permit special condition No. 16 states that the District requires notification in letter form 30 days prior to all farm field reactivation activities. The proposed modification of the permit will provide the District with an enhanced ability to inspect the reactivated farm fields. Inherent in such reactivation is ditching and diking of the fields. Such operations have been authorized since the 1980 permit was issued. The work associated with field reactivation will be conducted in accordance with existing design criteria as set forth in the application. Based on evidence admitted at the hearing, the permit modification should include the following special condition: Ditches and dikes associated with the farm fields encompassed by this authorization shall be constructed/maintained in conformance with the "Typical Field Layout And Detail Sheet," revised 10/12/93. The evidence establishes that the operations of the TCWMD as proposed by the permit modification application are within the authorization of the existing permit as previously modified. Otherwise stated, the award of this modification will have no substantial impact on the operation of the permitted surface water management system. The modification will result in no additional discharge of surface water from the control structures. The District has established water quantity criteria intended to insure that adverse impacts do not occur due to excess discharge. (Based upon the Hearing Officer's ruling on a District's Motion in Limine, water quality issues were not addressed at hearing.) The criteria are set forth at Chapter 40E-4.301, Florida Administrative Code, and in the Basis of Review. In relevant part, the District criteria require an applicant to provide reasonable assurances that the surface water management system provides adequate flood drainage and protection, that the system will not cause adverse water quantity impacts on receiving waters and adjacent lands, and that the system will not cause adverse impacts on surface and groundwater levels and flows. Modification of a permit must not result in additional adverse off-site impacts. In this case, reasonable assurances have been provided that the proposed modification will not exacerbate the historical and current drainage conditions. The permit modification application at issue does not propose to alter the rates or routes of water currently authorized for discharge from Telegraph Swamp. Reactivation of the farm fields will not impact receiving bodies in any manner different from that which presently exists under previous permits. In providing reasonable assurances, the TCWMD analyzed the water storage capacity available in the detention basins, performed flood routing projections and calculated peak discharge rates for the permit area. As required by the district, the TCWMD utilized a standard hypothetical 25-year/3- day storm event in order to determine whether sufficient capacity was available to handle the resulting stormwater. The projections provide reasonable assurances that the common detention areas have the capacity to provide adequate flood drainage and protection and are accepted. Rule 40E-4.091(1)(a), Florida Administrative Code, incorporates by reference a document identified as the "Basis of Review for Surface Water Management Permit Applications within the South Florida Water Management District--September 1989" Section 3.2.1.2.b requires that: the proposed project modification must meet the allowable discharge rate; and the allowable discharge rate for a previously permitted project is that which was set in the previous permit. The TCWMD prepared and submitted discharge calculations establishing that the post-development discharges will not exceed the discharge rate previously accepted by the District. Since 1984, the District has previously accepted a peak allowable discharge rate of 39 cubic feet per second per square mile (csm). The csm figure is based upon the historical TCWMD discharge rate within the Caloosahatchee River basin. As previously stated, reactivation of the farm fields will not impact the receiving bodies in any manner different from that which presently exists under previous permits. The District asserts that the 39csm discharge rate has been "permitted" since the 1984 modification was approved. The Petitioner asserts that the 39csm discharge rate has never been "permitted" by the District. The evidence establishes that since the 1984 application for permit modification, the discharge rate of 39csm has been utilized by TCWMD and has been accepted by the District, but that the actual permits do not specifically identify the discharge rate as 39csm. In projecting discharge rates, the TCWMD used a time of concentration of one hour. The time of concentration (T.O.C.) is the time in which water would move from the farm fields to the control structure in each sub-watershed. Otherwise stated, a projected T.O.C. of one hour means that the storm water would move from the field to the control structure in one hour. The T.O.C. of one hour is a conservative estimate and likely substantially overestimates the speed at which the water will move. The three basin areas contain a total of more than 80 square miles. Water will travel an average distance of two miles from field to detention basin through ditches, swales and existing low areas. Again conservatively, the TCWMD did not include projected travel time through such conveyances, resulting in a longer T.O.C. and resulting in a higher peak discharge rate than is probable. Although there appeared to be some confusion on the part of the District staff as to the application of the T.O.C. by the TCWMD, the TCWMD engineer who performed the calculation testified at hearing and was qualified as an expert witness in civil engineering, hydrology and surface water management. His testimony and projections are reasonable and are credited. Proposed SWM permit modification special condition No. 11 states that farm field discharge shall be directed to and conveyed via existing ditches, wetlands and/or sheetflow areas per existing site conditions. No new outfall ditches are permitted under this modification. Flood routings were calculated assuming all farm fields would be activated simultaneously and pumping the maximum capacity of 390 gallons per minute per acre (the equivalent of 20-21 inches of surface water pumped from each field daily). It is highly unlikely that all farm fields would be active simultaneously or that stormwater would continue to fall with such velocity to permit continued pumping at maximum capacity for an extended period. Even based on the conservative assumptions utilized by the TCWMD engineers, the projected peak discharge rate at the Telegraph Swamp control structure is 37csm to 38.5csm, within the maximum of 39csm previously accepted by the District. The computer modeling performed by the TCWMD engineer in calculating the peak discharge rate is accepted as reasonable. The TCWMD did not include offsite inflow in its analysis of projected capacity or discharge rates. There is anecdotal evidence that on occasion, water may flow into TCWMD from Jack's Branch or from across roadways to the north and west of the TCWMD; however, given the vast storage capacity of the TCWMD detention areas, there is no evidence that the quantity of offsite inflows is of such significance as to render the TCWMD projections unreasonable. As previously stated, the TCWMD calculations are reasonable and are accepted. The evidence establishes that the peak discharge rate resulting from approval of the instant permit modification will not exceed 39csm. The Petitioners offered their own peak discharge rate calculations, based on a "worst possible case scenario." The assumptions on which the Petitioners' projections are based are unreasonable and are rejected. Based on recommendations received at the hearing, the permit modification should include the following special condition: Pumped discharge from farm fields for which pumps are not currently installed shall be limited to 75 gallons per minute per acre of farmed area. Pumps are currently installed in fields number 7, 8, 9, 10, 12, 14, 15, 24 north and south, 28, east half of 34, 64, 67, 68, 69 and 80. The Petitioners assert that the system is currently causing adverse impacts to their properties in the form of flooding. The greater weight of the evidence establishes that the system presently does not cause adverse water quantity impacts on receiving waters and adjacent lands, and does not cause adverse impacts on surface and groundwater levels and flows. The evidence establishes that award of the application for permit modification will not adversely alter the current operations. It is clear that the Petitioners have been impacted by changes in the historical drainage patterns in the area; however, such changes had substantially occurred by 1980 when the original permit was issued. The greater weight of the credited evidence establishes that such impacts are not the result of the activities authorized in the original 1980 permit and in subsequent modifications, but instead are the result of unrelated actions by third parties not involved in this administrative proceeding. There is no credible evidence that the permit modification sought in the instant proceeding will adversely affect the Petitioners. The 1980 permit addresses existing water quantity problems in the area of the TCWMD project. For example, the construction of the Golden Grove Dike resulted in blockage of historical drainage towards Spanish Creek and the diversion of excess waters into Cypress Creek. During the 1980's the District required that culverts be installed in the Golden Grove Dike which eventually restored some surface water flow through the dike construction and on towards the south, although during some storm events water flow continues around the dike and into Cypress Creek. The Petitioners offered anecdotal evidence as to reduced water flows in some local creeks and increased flows thorough Cypress Creek. The Respondent offered evidence indicating that water flow through Cypress Creek may be less than 30 years ago, due to the digging of a canal between Spanish Creek and Cow Slough and the extension of the Clay Gully Canal's diversion of water into Telegraph Swamp. None of the evidence on this point was persuasive, however it is not relevant. Clearly, the instant permit modification application will not adversely affect the existing situation in the receiving bodies. The Petitioners assert that other receiving waterways have become clogged with vegetation, debris or soil, have accordingly reduced capacities, and are unable to accommodate historical discharge levels. Based on the lack of capacity, the Petitioners suggest that waters move towards the eastern portion of Telegraph Swamp and are discharged, flow towards, into and over the banks of Cypress Creek, and flood their properties. The TCWMD conducted a study of backwater profiles based upon credited field data. The study is found to be reasonable and is credited. Based upon the study, approximately 90 per cent of the water discharged from Telegraph Swamp is conveyed to the Caloosahatchee via Big Island Canal, Telegraph Creek and the swamp area south of the control structure. The remaining 10 per cent of the water enters the Bullhead Strand-Lightered Canal-Cypress Creek watercourse. Water flows from Telegraph Swamp into Cypress Creek via Bullhead Strand and the South Lightered Canal, however, the canal has become so restricted by vegetation that it provides little direct water flow between the strand and the creek and is more properly regarded as an area of enhanced sheet flow. The evidence does not establish that the surface water traveling from Bullhead Strand to Cypress Creek is of significance. Coupled with the existence of the Big Island Canal (which connects Telegraph Swamp to Telegraph Creek) it is unlikely that post-development surface water discharged from the Telegraph Swamp into Cypress Creek exceeds pre-development discharges. The Petitioners claim that two culverts in the Big Island canal restrict the flow of water through the canal and result in increased discharge to the east and to Cypress Creek. The greater weight of the evidence establishes that during period of time when the culverts are unable to accommodate water flow, the water travels into a broad flood plain, around the culverts and returns to the Big Island Canal. The evidence establishes that the proposed modification will not result in additional adverse off-site impacts. The adverse conditions affecting Cypress Creek existed at the time of the 1980 permit and are addressed in the staff report to that permit and to subsequent permit modifications. There is no credible evidence that modification of the permit as sought in this case will result in adverse impacts beyond those which have existed at the time of the award of the original permit. The Petitioners assert that the fields included within the permit modification application lack individual retention areas. The lack of individual detention areas is immaterial in this case where sufficient downstream detention capacity is available through the common detention areas. The Petitioners asserts that the Telegraph Swamp is an "above-ground impoundment" and that as such is fails to comply with requirements related to such water storage systems. The Telegraph Swamp is not a typical "above-ground impoundment" as that term is routinely applied by the District. The regulations addressed by the Petitioners clearly state that they are not intended to be inclusive and are intended to provide guidelines and basic performance criteria for commonly encountered south Florida situations. Telegraph Swamp is not a commonly encountered south Florida situation. There is no evidence that the decision not to apply the "above-ground impoundment" regulations to the Telegraph Swamp is unreasonable. The Petitioner suggest that the TCWMD application for permit modification is deficient and fails to provide information in compliance with the Basis of Review. The Basis of Review is directed towards applications for new construction. The District reasonably does not interpret the all elements of the Basis of Review to apply to existing operations. The original staff report for this permit modification application fails to acknowledge that Cypress Creek is a receiving body. However, as stated previously, the 1980 application and subsequent modifications have clearly addressed the fact that Telegraph Swamp waters discharge to Cypress Creek via intervening waterways. The failure to include the reference in the staff report to this application for modification is irrelevant.
Recommendation Based on the foregoing, it is hereby RECOMMENDED that the South Florida Water Management District enter a Final Order issuing Surface Water Management Permit Modification No. 08-00004-S including the additional permit conditions set forth herein, to the Telegraph Cypress Water Management District. DONE and RECOMMENDED this 1st day of April, 1994 in Tallahassee, Florida. WILLIAM F. QUATTLEBAUM 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 1st day of April, 1994.

Rejected, not supported by the greater weight of credible and persuasive evidence. The assumptions underlying the Petitioners' calculation of theoretical maximum discharge are rejected as unreasonable. Rejected, unnecessary. 36-45. Rejected, irrelevant. The anecdotal evidence fails to establish that offsite inflows are of such quantity as to render the TCWMD projections unreasonable.

Rejected, not supported by the greater weight of credible and persuasive evidence. The assumptions underlying the Petitioners' calculation of theoretical maximum discharge are rejected as unreasonable. Rejected, irrelevant. The greater weight of credible and persuasive evidence fails to establish that the cemetery flooding is related to actions by the TCWMD. Further, the evidence fails to establish that, even if the flooding was related to the TCWMD, the instant permit modification application will cause additional adverse impacts. Respondent Telegraph Cypress Water Management District Respondent Telegraph Cypress Water Management District's proposed findings of fact are accepted as modified and incorporated in the Recommended Order except as follows: 18. Rejected, subordinate. 19-20. Rejected, not credited and unnecessary. Rejected as to assertion that the 39csm discharge rate was set in the 1984 permit modification, not supported by the evidence. Review of the document admitted into evidence as the 1984 modification fails to reveal that the figure of 39csm is set forth therein. Rejected, cumulative. Rejected, unnecessary. Respondent South Florida Water Management District Respondent South Florida Water Management District's proposed findings of fact are accepted as modified and incorporated in the Recommended Order except as follows: 30. Rejected as to assertion that the 39csm discharge rate was set in the 1984 permit modification, not supported by the evidence. Review of the document admitted into evidence as the 1984 modification fails to reveal that the figure of 39csm is set forth therein. Pages 17-19 of the Proposed Recommended Order set forth revisions to the staff report which originally form the basis for the preliminary agency action in this matter. As the hearing is a de novo review of this matter, it is unnecessary for this Recommended Order to address the revision of the staff report, which has limited probative value.

The Issue Whether proposed Water Use Permits Nos. 20012236.000 (the Potable Water Permit) and 20012239.000 (the Irrigation Permit) and proposed Environmental Resource Permit No. 43020198.001 (the ERP) should be issued by the Respondent, Southwest Florida Water Management District (the District).
Findings Of Fact The Parties The individual Petitioners, Farnsworth, Roop, and Varnum are all Florida citizens and residents of Sumter County. None of the individual Petitioners offered any evidence relating to direct impacts that the ERP would have on their property. With respect to the Potable Water and Irrigation Permits, anecdotal testimony was presented by Petitioners and Wing and Weir relating to well failures and sinkholes in the area. Two Petitioners, Roop and Varnum, live in close proximity to the property encompassed by the three permits. Petitioner Farnsworth’s property is approximately three and a half miles from the project boundary. Wing and Weir live approximately four and a half to five and 18 miles from the project site, respectively. SCAID is a Florida not-for-profit corporation that has approximately 130 members. Farnsworth, the president of SCAID, identified only Roop and Varnum as members who will be directly affected by the activities to be authorized by the permits. The District is the administrative agency charged with the responsibility to conserve, protect, manage, and control water resources within its boundaries. The Utility and the Authority are limited liability companies, of which the Villages Inc. is the managing partner. The Villages Inc. is a Florida corporation. The Utility, which will serve as a provider of potable water, is regulated by the Public Service Commission, while the Authority which will provide irrigation water, is not. The Villages Inc., Development The Villages Inc. is a phased, mixed use, retirement community, which is located at the intersecting borders of Lake, Marion, and Sumter Counties. Development has been on going since at least 1983, with a current planning horizon of the year 2019. Currently, there are 15,362 constructed dwelling units in the built-out portion of the Villages Inc. that are located in Lake County and the extreme northeast corner of Sumter County. The portion located in Marion County is 60 percent complete, with 750 homes completed and another 600 under construction. Approximately another 22,000 residences are planned for development in Sumter County by the year 2012, with an additional 10,200 by the year 2019. However, the Potable Water and Irrigation Permits are only for a six-year duration, and the ERP has a duration of only six years. None of the permits authorize development activities beyond that time frame. Generally speaking, the three permits at issue include an area owned by the Villages Inc. that lies in northeast Sumter County South of County Road 466 and North of County Road 466A. However, it is not projected that this entire area will be built-out during the terms of three proposed permits. Area Hydrology and Topography In the area of the Villages Inc., there is a layer of approximately five to ten feet of sand at the land surface, which is underlain by ten to 70 feet of a clayey sand. Both of these constitute the surficial aquifer and are extremely leaky, allowing water to percolate easily through to a lower layer. Except in the vicinity of Lake Miona, there is no water in the surficial aquifer except after rainfall events. The clayey sand layer is underlain by the Upper Floridan, a limestone unit. The top of this limestone layer ("the top of the rock") occurs at fluctuating depths of between 30 and 70 feet. At approximately 350 to 400 feet below the land surface, there begins a transition to a denser unit that serves as a confining layer between the Upper Floridan production zone and the Lower Floridan production zone. This confining layer, which was confirmed by drilling at three locations in the Villages Inc. is approximately 150 feet thick in the area of the Villages Inc. Another transition, this time to a less dense formation, begins at approximately 550 to 600 feet, which is considered the top of the Lower Floridan production zone. While testing conducted on the project site indicated almost no leakage between the Upper and Lower Floridan production zones, it is generally known by experts that there is some exchange of water between the two layers. Both the Upper and the Lower Floridan contain water that meets potable water standards and both are considered water production zones. The water quality of the two zones is not significantly different. The project area is prone to karst activity, that is, the formation of sinkholes. Sinkholes are formed as a result of the collapse of the overburden above subsurface cavities which have been formed through a very gradual dissolution of limestone, thus resulting in a "sink" at the land surface. Surface water bodies in the area include Lake Miona, Black Lake, Cherry Lake, and Dry Prairie, as well as several other small wetlands. The Potable Water and Irrigation Permits The potable water permit is for the withdrawal from the Upper Floridan Aquifer of 1.164 million gallons of water per day (MGD), on an annual average, for potable use in residences and both commercial and recreational establishments. It also limits the maximum withdrawal during peak months to 2.909 MGD. The Irrigation Permit is for the withdrawal from the Lower Floridan Aquifer of 2.850 MGD, on an annual average, for use in irrigation. The peak month usage rate permissible under the proposed permit would be 9.090 MGD. Water withdrawal under the Irrigation Permit will be used for the irrigation of residential lawns, common areas, commercial landscaping, and golf courses. Modeling of Drawdowns In assessing the impacts of proposed water withdrawals from an aquifer, District personnel considered effects on the aquifers and on-surface water features in the area. Computer- generated models of the predicted effects of the Potable Water and Irrigation Permits withdrawals provided one of the principal bases for this assessment. The primary geologist assigned to review the permit applications reviewed two of the models submitted by the Utility and the Authority (jointly the WUP Applicants) and ran one personal model of her own in order to predict the effects of the proposed withdrawals on the aquifers, as well as on any wetlands and other surface water bodies. In particular, the models predict both the vertical and horizontal extent to which the withdrawals may lower the level of water within the aquifers and in-surface waters under various conditions. One of the models submitted by the WUP Applicants predicted drawdowns during a 90-day period of no rainfall while the other predicted the impacts of the withdrawals over the life of the permits, considered cumulatively with the effects of withdrawals from the already-existing Villages' development in Sumter, Marion, and Lake Counties. The District’s geologist modeled the impacts of the withdrawals over the life of the permits and included the cumulative effects of all of the current Villages' withdrawals in Sumter County. All of these models included the combined effects of both the proposed Potable Water and the Irrigation Permits. Based upon these models, it is concluded that there will be no significant drawdowns as a result of the withdrawals authorized by the proposed water use permits. Specifically, the only predicted drawdown in the surficial aquifer (0.25 feet of drawdown) is in an area where there are no natural surface water features. Drawdown in the Upper Floridan is predicted at between 0.1 and 0.2 feet, while the drawdown in the Lower Floridan is predicted at a maximum of 1.5 feet. These minor drawdowns are not expected to cause any adverse impacts. Transmissivity is the rate at which water moves horizontally through the aquifer. In areas with high transmissivity, the results of water withdrawals from an aquifer will generally be low in magnitude, but broad in lateral extent. Water withdrawals from areas of low transmissivity will result in cones of depression that are more limited in lateral extent, but steeper vertically. The use of too high a transmissivity rate in a model, would overpredict the horizontal distance of the drawdowns caused by withdrawals, but would underpredict the vertical drawdown in the immediate vicinity of the withdrawal. Conversely, use of too low a transmissivity would over-predict the effects in the immediate vicinity of the withdrawal but underpredict the lateral extent of the drawdown. The WUP Applicants’ models used a transmissivity value for the Lower Floridan Aquifer of 100,000 feet squared per day ("ft.2/d'). The WUP Applicants’ consultant derived the transmissivity values from a regional model prepared by the University of Florida. The regional model uses a transmissivity value for the entire region of 200,000 ft.2/d for the Lower Floridan. While that transmissivity is appropriate for assessing large-scale impacts, on a more localized level, the transmissivity of the aquifer may be lower. Therefore, the WUP Applicants’ consultant met with District representatives and agreed to use a value half that used in the University of Florida model. A similar approach was used for the transmissivity value used in modeling effects in the Upper Floridan. Notably, specific transmissivity values recorded in four wells in the Villages Inc. area were not used because two of these wells were only cased to a depth of just over 250 feet, with an open hole below that to a depth of 590 feet. Thus, the transmissivity measured in these wells reflect conditions in the confining layer at the immediate location of the wells - not the transmissivity of the Lower Floridan production zone. Further, site-specific information on transmissivity, measured during pump tests at individual wells, does not correlate well to the transmissivity of the aquifer, even at short distances from the well. Transmissivities measured at individual wells are used to determine the depth at which the pump should be set in the well, not to determine the transmissivity of the aquifer. Thus, the use of transmissivities derived from the regional model, but adjusted to be conservative, is entirely appropriate. Moreover, using a transmissivity in her modeling of the project impacts of 27,000 ft.2/d for the Lower Floridan Aquifer, the district geologist’s model predicted no adverse impacts. Leakance is the measure of the resistance of movement vertically through confining units of the aquifer. The leakance value used by the District for the confining layer between the Upper and Lower Floridan was taken from the University of Florida model. Tests conducted on the site actually measured even lower leakance values. Thus, the evidence establishes that the leakance value used in the WUP Applicants’ and the District’s modeling for the Floridan confining layer was reasonable and appropriate. Competent, substantial evidence also establishes that the leakance value used for Lake Miona was reasonable. The WUP Applicants submitted to the District substantial data, gathered over several years, reflecting the balance of water flowing into Lake Miona and the lake’s levels in relation to the potentiometric surface. This documentation verified the leakance value used for Lake Miona in the modeling. Finally, the District modeling used appropriate boundary condition parameters. The District modeling used what is known as the "constant head" boundary and assumes the existence of water generated off-site at the boundaries. Such a boundary simulates the discharge of the aquifer at a certain level. The use of constant head boundaries is an accepted practice. The modeling conducted on behalf of the District and the Applicants provides a reasonable assurances that the Potable Water and Irrigation Permits will not cause adverse water quality or quantity changes to surface or groundwater resources, will not cause adverse environmental impacts to natural resources, and will not cause pollution of the aquifer. Furthermore, because the predicted drawdowns are so insignificant, reasonable assurances have been provided that the withdrawals will not adversely impact existing off-site land uses or existing legal withdrawals. The modeling also provides reasonable assurances that the withdrawals will not be harmful to the water resources of the District. Moreover, monitoring requirements included in the proposed Potable Water and Irrigation Permits provide additional reasonable assurance that – should the withdrawal effects exceed those predicted by the modeling – such effects are identified and necessary steps are taken to mitigate for any potential impacts. The District has reserved the right to modify or revoke all or portions of the water use permits under certain circumstances. Specifically, the proposed Potable Water Permit requires a monitoring plan that includes the following pertinent provisions: There shall be no less than three control wetland and ten onsite wetland monitoring sites; A baseline monitoring report, outlining the current wetland conditions; * * * A statement indicating that an analysis of the water level records for area lakes, including Miona Lake, Black Lake, Cherry Lake, Lake Deaton and Lake Griffin, will be included in the annual report; A statement indicating that an analysis of the spring flow records for Gum Spring, Silver Spring, and Fenney Spring, will be included in the annual report; * * * Wildlife analyses for potentially impacted wetlands, lakes, and adjacent property owner uses or wells, including methods to determine success of the mitigation; A mitigation plan for potentially impacted wetlands, lakes, and adjacent property owner uses or wells, including methods and thresholds to determine success of the mitigation; An annual report of an analysis of the monitoring data . . . . Similar provisions are included in the proposed irrigation permit. The WUP Applicants, in conjunction with the District, have developed sites and methodologies for this monitoring. Reasonable Demand The water to be withdrawn under the proposed Potable Water Permit will serve 10,783 people. This total results from the simple multiplication of the number of residences to be built during the next six years (5,675) by the average number of residents per household (1.9). Those numbers are based upon historical absorption rates within the Villages Inc. development since 1983, an absorption rate that doubles approximately every five years. The Utility proposed a per capita use rate of 108 gallons per day for potable use only. District personnel independently verified that per capita rate, based upon current usage in the existing portions of the Villages Inc. and determined that the rate was reasonable. Based upon the population projections and the per capita rate, the District determined that there is a reasonable demand for the withdrawal of the amount of water, for potable purposes, that is reflected in the Potable Water Permit. The Utility has provided reasonable assurance regarding the Utility’s satisfaction of this permitting criterion. As to the irrigation permit, the Villages Inc. plans, within the next six years, to complete the construction of 1,911 acres of property that will require irrigation. The amount of water originally requested by the Authority for irrigation withdrawals was reduced during the course of the application process at the request of the District. The District determined the reasonable amount of irrigation water needed through the application of AGMOD, a computer model that predicts the irrigation needs of various vegetative covers. Since the Authority intends to utilize treated wastewater effluent as another source of irrigation water, the District reduced the amount of water that it would permit to be withdrawn from the Lower Floridan for irrigation. The District, thus, determined that the Authority would need 1.59 MGD annual average for recreational and aesthetic area irrigation and 1.26 MGD annual average for residential lawn irrigation, for a total of 2.85 MGD. The Villages Inc. also plans to accumulate stormwater in lined ponds for irrigation use. However, unlike its treatment of wastewater effluent, the District did not deduct accumulated stormwater from the amount of water deemed necessary for irrigation. This approach was adopted due to the inability to predict short-term rainfall amounts. The uncontroverted evidence of record establishes reasonable assurances that there is a reasonable demand for the amount of water to be withdrawn under the proposed irrigation permit. Conservation and Reuse Measures Both the Utility and the Authority applications included proposed measures for the conservation and reuse of water. The conservation plan submitted in conjunction with the irrigation permit application provides for control valves to regulate both the pressure and timing of irrigation by residential users; contractual restrictions on water use by commercial users; xeriscaping; and an irrigation control system for golf course irrigation that is designed to maximize the efficient use of water. In addition, in the proposed permits, the District requires the Utility and the Authority to expand upon these conservation measures through such measures as educational efforts, inclined block rate structures, and annual reporting to assess the success of conservation measures. The Authority also committed to reduce its dependence on groundwater withdrawals through the reuse of wastewater effluent, both from the on-site wastewater treatment facility and through contract with the City of Wildwood. Reasonable assurances have been provided that conservation measures have been incorporated and that, to the maximum extent practicable, reuse measures have been incorporated. Use of Lowest Available Quality of Water In addition to the reuse of treated wastewater effluent, the Authority intends to minimize its dependence on groundwater withdrawals for irrigation use through the reuse of stormwater accumulated in lined ponds. Thirty-one of the lined stormwater retention ponds to be constructed by the Villages Inc. are designed as a component of the irrigation system on-site. Ponds will be grouped with the individual ponds within each group linked through underground piping. There will be an electronically controlled valve in the stormwater pond at the end of the pipe that will be used to draw out water for irrigation purposes. These lined stormwater ponds serve several purposes. However, the design feature that is pertinent to the reuse of stormwater for irrigation is the inclusion of additional storage capacity below the top of the pond liner. No groundwater will be withdrawn for irrigation purposes unless the level of stormwater in these lined ponds drops below a designed minimum irrigation level. Groundwater pumped into these ponds will then be pumped out for irrigation. Thus, the use of groundwater for irrigation is minimized. The Authority has met its burden of proving that it will use the lowest quality of water available. With respect to the potable permit, the evidence establishes that there are only minor differences between the water quality in the Upper Floridan and Lower Floridan in this area. The Upper Floridan is a reasonable source for potable supply in this area. Thus, reasonable assurances have been provided by the Utility that it will utilize the lowest water quality that it has the ability to use for potable purposes. Waste of Water In regard to concerns that the design of the Villages Inc.'s stormwater/irrigation system will result in wasteful losses of water due to evaporation from the surface of the lined ponds, it must be noted that there are no artesian wells relating to this project and nothing in the record to suggest that the groundwater withdrawals by either the Utility or the Authority will cause excess water to run into the surface water system. Additionally, the evidence establishes that, to the extent groundwater will be withdrawn from the Lower Floridan and pumped into lined stormwater ponds, such augmentation is not for an aesthetic purpose. Instead, the groundwater added to those ponds will be utilized as an integral part of the irrigation system and will be limited in quantity to the amount necessary for immediate irrigation needs. Finally, the water to be withdrawn will be put to beneficial potable and irrigation uses, rather than wasteful purposes. Under current regulation, water lost from lined stormwater ponds through evaporation is not considered as waste. Thus, the Authority and the Utility have provided reasonable assurances that their withdrawals of groundwater will not result in waste. The ERP The stormwater management system proposed by the Villages Inc. will eventually serve 5,016 acres on which residential, commercial, golf course, and other recreational development will ultimately be constructed. However, the proposed permit currently at issue is preliminary in nature and will only authorize the construction of stormwater ponds, earthworks relating to the construction of compensating flood storage, and wetland mitigation. Water Quality Impacts The stormwater management system will include eight shallow treatment ponds that will be adjacent to Lake Miona and Black Lake and 45 lined retention ponds. Thirty-one of these lined ponds will serve as part of the irrigation system for a portion of the Villages Inc.'s development. All of these ponds provide water quality treatment. The unlined ponds will retain the first one inch of stormwater and then overflow into the lakes. The ponds provide water quality treatment of such water before it is discharged into the lakes. The water quality treatment provided by these ponds provides reasonable assurances that the project will not adversely impact the water quality of receiving waters. While they do not discharge directly to surface receiving waters, the lined retention ponds do provide protection against adverse water quality impacts on groundwater. There will be some percolation from these ponds, from the sides at heights above the top of the liner. However, the liners will prevent the discharge of pollutants through the highly permeable surface strata into the groundwater. The Villages Inc. designed the system in this manner in response to concerns voiced by the Department of Environmental Protection during the DRI process regarding potential pollutant loading of the aquifer at the retention pond sites. Furthermore, by distributing the accumulated stormwater - through the irrigation system - over a wider expanse of vegetated land surface, a greater degree of water quality treatment will be achieved than if the stormwater were simply permitted to percolate directly through the pond bottom. There is no reasonable expectation that pollutants will be discharged into the aquifer from the lined ponds. If dry ponds were used, there would be an accumulation of pollutants in the pond bottom. These measures provide reasonable assurances that there will be no adverse impact on the quality of receiving waters. Water Quantity Impacts With regard to the use of lined retention ponds, as part of the Villages Inc.’s stormwater system and the impact of such ponds on water quantity, the evaporative losses from lined ponds as opposed to unlined ponds is a differential of approximately one (1) inch of net recharge. The acreage of the lined ponds - even measured at the very top of the pond banks - is only 445 acres. That differential, in terms of a gross water balance, is not significant, in view of the other benefits provided by the lined ponds. As part of the project, wetlands will be created and expanded and other water bodies will be created. After rainfalls, these unlined ponds will be filled with water and will lose as much water through evaporation as would any other water body. The design proposed by the Villages Inc., however, will distribute the accumulated stormwater across the project site through the irrigation of vegetated areas. The documentation submitted by the Villages Inc. establishes that the ERP will not cause adverse water quantity impacts. The Villages Inc. has carried its burden as to this permitting criterion. Flooding, Surface Water Conveyance, and Storage Impacts Parts of the project are located in areas designated by the Federal Emergency Management Administration (FEMA) as 100-year flood zones. Specifically, these areas are located along Lake Miona, Black Lake, between Black Lake and Cherry Lake, and at some locations south of Black Lake. Under the District’s rules, compensation must be provided for any loss of flood zone in filled areas by the excavation of other areas. The District has determined, based upon the documentation provided with the Villages Inc.’s application, work on the site will encroach on 871.37 acre feet of the FEMA 100-year flood zone. However, 1,051.70 acre feet of compensating flood zone is being created. The Villages Inc. proposes to mitigate for the loss of flood zone primarily in the areas of Dry Prairie and Cherry Lake. At present, Cherry Lake is the location of a peat mining operation authorized by DEP permit. Mining has occurred at that site since the early 1980s. The flood zone mitigation proposed by the Villages Inc. provides reasonable assurance that it will sufficiently compensate for any loss of flood basin storage. The Villages Inc.'s project provides reasonable assurance that it will neither adversely affect surface water storage or conveyance capabilities, surface or groundwater levels or surface water flows nor cause adverse flooding. Each of the 45 retention ponds to be constructed on-site will include sufficient capacity, above the top of the pond liner, to hold a 100-year/24-hour storm event. This includes stormwater drainage from off-site. In addition, these ponds are designed to have an extra one foot of freeboard above that needed for the 100-year/24-hour storm, thus providing approximately an additional 100 acres of flood storage beyond that which will be lost through construction on-site. Furthermore, the Villages Inc. has proposed an emergency flood plan. In the event of a severe flood event, excess water will be pumped from Dry Prairie, Cherry Lake, and Lake Miona and delivered to the retention ponds and to certain golf course fairways located such that habitable living spaces would not be endangered. Environmental Impacts and Mitigation There are 601 acres of wetlands and surface waters of various kinds in the Villages Inc.’s project area. Forty-one acres of wetlands will be impacted by the work that is authorized under the ERP. Each of these impacted wetlands, along with the extent of the impact, is listed in the ERP. The impacts include both fill and excavation and all will be permanent. When assessing wetland impacts and proposed mitigation for those impacts, the District seeks to ensure that the activities proposed will not result in a net loss of wetland functionality. The object is to ensure that the end result will function at least as well as did the wetlands in their pre-impact condition. Functional value is judged, at least in part, by the long term viability of the wetland. While small, isolated wetlands are not completely without value, large wetland ecosystems – which are less susceptible to surrounding development – generally have greater long-term habitat value. The District’s policy is that an applicant need not provide any mitigation for the loss of habitat in wetlands of less than 0.5 acre, except under certain limited circumstances, including where the wetland is utilized by threatened or endangered species. Some wetlands that will be impacted by the Villages Inc.’s project are of high functional value and some are not as good. The Villages Inc. proposes a variety of types of mitigation for the wetlands impacts that will result from its project, all of which are summarized in the ERP. In all, 331.55 acres of mitigation are proposed by the Villages Inc. First, the District proposes to create new wetlands. Approximately 11 acres of this new wetland will consist of a marsh, which is to be created east of Cherry Lake. Second, it proposes to undertake substantial enhancement of Dry Prairie, a 126-acre wetland. Currently – and since at least the early nineties – Dry Prairie received discharge water from the peat mining operation at Cherry Lake. Without intervention, when the mining operations stop, Dry Prairie would naturally become drier than it has been for several years and would lose some of the habitat function that it has been providing. The Villages Inc.’s proposed enhancement is designed to match the current hydroperiods of Dry Prairie, thus ensuring its continued habitat value. Third, the Villages Inc. has proposed to enhance upland buffers around wetlands and surface waters by planting natural vegetation, thus providing a natural barrier. Placement of these buffers in conservation easements does not provide the Villages Inc. with mitigation credit, since a 25-foot buffer is required anyway. However, the District determined that the enhancement of these areas provided functional value to the wetlands and surface waters that would not be served by the easements alone. Fourth, the Villages Inc. will place a conservation easement over certain areas, including a 1500-foot radius preserve required by the Fish and Wildlife Conservation Commission (FWCC) around an identified eagles’ nest. These areas will also be used for the relocation of gopher tortoises and, if any are subsequently located, of gopher frogs. While the Villages Inc. is also performing some enhancement of this area, it will receive no mitigation credit for such enhancement – which was required to meet FWCC requirements. However, since the conservation easement will remain in effect in perpetuity, regardless of whether the eagles continue to use the nest, the easement ensures the continued, viability of the area’s wetlands and provides threatened and endangered species habitat. In order to provide additional assurances that these mitigation efforts will be successful, the District has included a condition in the proposed permit establishing wetland mitigation success criteria for the various types of proposed mitigation. If these success criteria are not achieved, additional mitigation must be provided. With the above described mitigation, the activities authorized under the ERP will not adversely impact the functional value of wetlands and other surface waters to fish or wildlife. The Villages Inc. has met its burden of providing reasonable assurances relating to this permit criterion. Capability of Performing Effectively The Villages Inc. has also provided reasonable assurances that the stormwater management system proposed is capable of functioning as designed. The retention ponds proposed are generally of a standard-type design and will not require complicated maintenance procedures. In its assessment of the functional capability of the system, the District did not concern itself with the amount of stormwater that the system might contribute for irrigation purposes. Rather, it focused its consideration on the stormwater management functions of the system. The question of the effectiveness of the system for irrigation purposes is not relevant to the determination of whether the Villages Inc. has met the criteria for permit issuance. Consequently, the record establishes that the documentation provided by the Villages Inc. contains reasonable assurances that the stormwater system will function effectively and as proposed. Operation Entity The Villages Inc. has created Community Development District No. 5 (CDD No. 5), which will serve as the entity responsible for the construction and maintenance of the stormwater system. CDD No. 5 will finance the construction through special revenue assessment bonds and will finance maintenance through the annual assessments. Similar community development districts were established to be responsible for earlier phases of the Villages Inc. The ERP includes a specific condition that, prior to any wetlands impacts, the Villages Inc. will either have to provide the District with documentation of the creation of a community development district or present the District with a performance bond in the amount of $1,698,696.00. Since the undisputed testimony at hearing was that CDD No. 5 has, in fact, now been created, there are reasonable assurances of financial responsibility. Secondary and Cumulative Impacts The Villages Inc.’s application also provides accurate and reliable information sufficient to establish that there are reasonable assurances that the proposed stormwater system will not cause unacceptable cumulative impacts upon wetlands or other surface waters or adverse secondary impacts to water resources. The system is designed in a manner that will meet water treatment criteria and there will be no secondary water quality impacts. Further, the use of buffers will prevent secondary impacts to wetlands and wetland habitats and there will be no secondary impacts to archeological or historical resources. In this instance, the stormwater system proposed by the Villages Inc. will function in a manner that replaces any water quantity or water quality functions lost by construction of the system. In its assessment of the possible cumulative impacts of the system, the District considered areas beyond the bounds of the current project, including the area to the south that is currently being reviewed under the DRI process as a substantial deviation. The District’s environmental scientist, Leonard Bartos, also reviewed that portion of the substantial deviation north of County Road 466A, in order to determine the types of wetlands present there. Furthermore, the District is one of the review agencies that comments on DRI and substantial deviation applications. When such an application is received by the District’s planning division, it is routed to the regulatory division for review. The District includes its knowledge of the DRIs in its determination that there are no cumulative impacts. Reasonable assurances have been provided as to these permitting criteria. Public Interest Balancing Test Because the proposed stormwater system will be located in, on, and over certain wetlands, the Villages Inc. must provide reasonable assurances that the system will not be contrary to the public interest. This assessment of this permitting criteria requires that the District balance seven factors. While the effects of the proposed activity will be permanent, the Villages Inc. has provided reasonable assurances that it will not have an adverse impact on the public health, safety, or welfare; on fishing or recreational values; on the flow of water; on environmental resources, including fish and wildlife and surface water resources; or on off-site properties. Furthermore, the District has carefully assessed the current functions being provided by the affected wetland areas. With respect to historical or archeological resources, the Villages Inc. has received letters from the Florida Department of State, Division of Historical Resources, stating that there are no significant historical or archeological resources on the project site that is the subject of this permit proceeding. Thus, the evidence establishes reasonable assurances that the Villages Inc.'s stormwater system will not be contrary to the public interest. Additionally, the District and Applicant presented uncontroverted evidence that the proposed project will not adversely impact a work of the District, and that there are no applicable special basin or geographic area criteria.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is: RECOMMENDED that a final order be entered issuing Water Use Permit Nos. 20012236.000 and 20012239.000 and Environmental Resource Permit No. 43020198.001, in accordance with the District’s proposed agency action.

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.

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 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.
