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

The Issue Whether Petitioner should be granted No Notice General Environmental Resource Permits for Lots 61, 245, and 247 within Unit of Development 11 of the Indian Trail Improvement District, pursuant to permitting criteria of Chapter 373, Part IV, Florida Statutes, Chapters 40E-40 and 40E-400, Florida Administrative Code, and the South Florida Water Management District's "Basis of Review for Environmental Resource Permit Applications Within the South Florida Water Management District--November 1996."
Findings Of Fact Petitioner, Royal Palm Beach Colony (Royal Palm), is a limited partnership registered and authorized to do business in the State of Florida. Respondent, South Florida Water Management District (SFWMD), is a public corporation existing by virtue of Chapter 25270, Laws of Florida, 1949, and operating pursuant to Chapter 373, Florida Statutes, and Title 40E, Florida Administrative Code, as a water management district, with its principal office in West Palm Beach, Florida. Intervenor, 1000 Friends of Florida, Inc., is a not- for-profit, tax exempt membership corporation, organized and existing under the laws of the State of Florida. Intervenor, Indian Trail Improvement District (ITID), is a special district of the State of Florida established by special act of the Legislature, Chapter 57-646, Laws of Florida, and operating pursuant to applicable provisions of Chapter 298, Florida Statutes, as well as special acts of the Legislature. Royal Palm owns approximately 171 lots within Unit of Development 11 of ITID (Unit 11) in Palm Beach County, Florida. Each lot is approximately 1.25 acres. Not all of the lots owned by Royal Palm in Unit 11 are contiguous. Unit 11 is a rural subdivision within ITID, in which there are numerous private property owners. The property of Royal Palm that is the subject of dispute is comprised of three lots, Lots 61, 245, and 247. Unit 11 is within the C-18 Basin. Prior to the construction of the C-18 Canal, the area was typically drained by sheet flow to the north. Because of the flat topography, the drainage in the C-18 Basin is poor; therefore, following periods of heavy rainfall much of the land is inundated. Unit 11 contains an extensive amount of wetlands. There are currently no habitable structures within Unit 11. It consists of vacant lots with an interconnected network of roads, canals, and roadside swales. On August 15, 1975, SFWMD's predecessor, The Central and Southern Florida Flood Control District, issued ITID a surface water management permit, Permit No. 50-00136-S (the 1975 permit) for construction and operation of a surface water management system serving Unit 11. The permit authorizes discharge from Unit 11 to the west leg of the C-18 canal via three culverts. In 1988, SFWMD undertook a comprehensive examination of the C-18 Basin, which resulted in a publication entitled "Technical Publication 88-11, Flood Management Study of the C- 18 Basin, August, 1988." The study documented that the western leg of the C-18 canal lacked capacity to accept the permitted discharge from Unit 11. SFWMD determined that the development of Unit 11's flood control and water quantity management system according to Permit No. 50-00136-S would be inconsistent with the overall objectives of SFWMD, harmful to the water resources and the public's health, safety, and welfare, and to the policies and purposes of Chapter 373, Florida Statutes, and not in the best interest of future residents of Unit 11. SFWMD and ITID entered into a consent agreement concerning Unit 11 on July 7, 1989 (the Consent Agreement). SFWMD and ITID agreed that ITID would apply for, process, and obtain a modification of Permit No. 50-00136-S to address and resolve SFWMD's flooding and water quality concerns. In addition, ITID was to construct the surface water management system authorized in the permit modification in accordance with the terms of the permit. ITID received a permit from SFWMD in 1990 authorizing modifications to the surface water management system in order to address the issues identified in the Consent Agreement, namely potential flooding of homes constructed for future residents of Unit 11. The improvements approved in the 1990 permit were never implemented, and the permit expired. In 1992, ITID proposed a different modification to the surface water management system that proposed an impoundment for retention of stormwater. The permit application was recommended for denial by SFWMD staff, but has never been presented to the SFWMD Governing Board for final agency action. The problems regarding the water quality and flooding problems set forth in the Consent Agreement have not been remedied. On December 4, 1997, Royal Palm obtained variances from the Palm Beach County Health Department (the Health Department), granting Royal Palm the right under certain specified conditions to construct on-site sewage treatment and disposal systems (OSTD Systems) on Lots 61, 245, and 247. Originally, the Health Department had denied Royal Palm's request for permission to construct the OSTD Systems on lots 61, 245, and 247 on the grounds that the lots were located in an area subject to frequent flooding and the drainage in the subdivision had not been constructed in accordance with SFWMD's requirements. Subsequent to the granting of the variance, Royal Palm revised its site plans for the three lots, and those revised plans have not been reviewed by the Health Department for compliance with applicable rules. On March 19, 1998, Royal Palm notified SFWMD that Royal Palm was entitled to a No Notice General Permit (NNGP) for Lots 61, 245, and 247 for activities in uplands pursuant to Rule 40E-400.315, Florida Administrative Code. On April 9, 1998, SFWMD issued its agency action by letter that informed Royal Palm that SFWMD staff had determined that the three lots did not qualify for a NNGP. The letter stated the reasons for denial as follows: Reasonable assurances have not been provided to show that the proposed system or project is not part of a larger common plan of development. See Rule 40E- 400.315(1)(f), Fla. Admin. Code. Royal Palm Colony is the owner of approximately 170 lots within Unit 11 of the Indian Trail Improvement District, and the three proposed lots appear to be merely part of this large common plan of development. Reasonable assurances have not been provided to show that construction and/or operation of the proposed system with use of septic systems and the associated lack of water quality treatment will not cause pollution in violation of water quality standards. See Rule 40E-4.301(1)(e), and 40E-400.215(11), Fla. Admin. Code. There is not a viable or functioning stormwater management system in place or proposed to provide reasonable assurance that the septic systems would properly function. Reasonable assurances have not been provided to show that construction and/or operation of the proposed system will not cause adverse secondary impacts to the water resources, including, but not limited to, significant interference with the construction and operation of a regional stormwater system needed for adequate flood protection and stormwater treatment in the Unit 11 area. See Rule 40E-400.301(1)(f), Fla. Admin. Code. Reasonable assurances have not been provided to show that construction and/or operation of the proposed system will not cause water quality impacts to receiving waters and adjacent lands. See Rule 40E- 4.301(1)(a), Fla. Admin. Code. The proposed project adds impervious area and eliminates water storage. This consideration is especially relevant when considering the larger common plan of development. Reasonable assurance has not been provided to show that construction and/or operation of the proposed system will not cause adverse flooding to on-site and or/or (sic) off-site properties. See Rule 40E- 4.301(10)(b), Fla. Admin. Code. The proposed project adds impervious area and eliminates water storage. This consideration is especially relevant when considering the larger common plan of development. Reasonable assurances have not been provided to show that construction and/or operation of the proposed system will not cause adverse impacts to existing surface water storage and conveyance capabilities. See Rule 40E-4.301(10)(c), Fla. Admin. Code. The proposed project adds impervious area and eliminates water storage. This consideration is especially relevant when considering the larger common plan of development. Reasonable assurance has not been provided to show that construction and/or operation of the proposed system will not adversely impact the value of functions provided to fish and wildlife and listed species and other surface waters. See Rule 40-4.301(1)(d), Fla. Admin. Code. This consideration is especially relevant when considering the larger common plan of development. Reasonable assurance has not been provided to show that the proposed system or project is capable, based on generally accepted engineering and scientific principles, of being performed and of functioning as proposed. See Rule 40E- 4.301(1)(i), Fla. Admin. Code. On April 23, 1998, Royal Palm filed its Petition for Formal Administrative Hearing with the clerk of SFWMD, initiating this proceeding. Rule 40E-400.315(1)(f), Florida Administrative Code, is intended to authorize only very minor activities that have no potential to cause harm to water resources. Because the NNGP is issued by rule, SFWMD does not typically review projects that are conducted pursuant to a NNGP. A NNGP does not authorize projects that are part of a common plan of development or sale. In determining whether an activity is within a larger common plan of development, SFWMD staff look to see whether the project has shared infrastructure that facilitates development, such as canals, swales, and roads. A surface water management is in place in Unit 11. It consists of roads, swales, and drainage canals. The system drains to the C-18 canal via three culverts. The system was put into place as a result of the issuance of the 1975 permit, but there have been no modifications to the system as required by the Consent Agreement. During the last ten years ITID has done minimal maintenance to the system. A common road network within Unit 11 provides access to each of the three lots. The lots will depend on the swales and drainage canals as part of overall stormwater management system that serves Unit 11. Unit 11 is a common plan of development. Accordingly, the activities proposed by Royal Palm, filling in order to construct three single family houses with driveways, mounded septic tank systems, and wells within Unit 11 are not authorized pursuant to a NNGP. Royal Palm's predecessor company originally owned all the lots in Unit 11. Royal Palm is presently liquidating its assets. Royal Palm selected the three lots at issue in this case for permitting for individual homes because the lots represented a good overview of the different types of Royal Palm's holdings in the area. If Royal Palm is able to build homes on the three lots and depending on the market conditions and other outside factors, Royal Palm will make a decision on how to liquidate the other 168 lots in Unit 11. It is anticipated that the construction of the homes on the lots at issue will involve placement of fill. Land development, including the placement of fill, displaces stormwater that would, on a property in its natural condition, pond on the surface or soak into the ground. In order to determine whether a project complies with the flood protection criteria, SFWMD staff must consider the effect the proposed land development has off-site, and the effects surrounding lands may have on the lot to be developed. The flood routing calculations provided by Royal Palm in its application did not provide any analysis of how discharges from surrounding properties would affect the performance of the surface water management systems constructed on the lots at issue. Nor did Royal Palm address the potential for flooding of off-site properties by stormwater displaced by fill and impervious areas that are contemplated on Lots 61, 245, and 247. The three lots are not hydrologically separate from the remainder of Unit 11. Royal Palm's failure to include a detailed analysis of the surrounding area also precluded SFWMD from making a determination as to the impacts of the proposed activities upon existing surface water storage and conveyance capabilities. The proposed projects are single family houses. It is reasonable to expect that some discharge of untreated stormwater runoff from the system directly into wetlands and other surface water will occur. For Lots 245, 247, and 61, the proposed stormwater management system includes a dry detention area. Considering the topographic information for this site, part of the runoff from the fill area will not flow into the dry detention area but will flow untreated directly into wetlands and other surface waters. The runoff could reasonably be expected to include oils, grease, and petroleum from the driveway area and herbicide and pesticides from the yard area. The untreated runoff could pose an adverse impact. Development adjacent to wetlands has the potential to disrupt the usage of those wetlands by wildlife. Section 4.2.7 of the Basis of Review provides that secondary impacts to the habitat functions of wetlands associated with adjacent upland activities are not considered adverse if buffers with a minimum width of 15 feet and an average width of 25 feet are provided abutting those wetlands. In certain circumstances, additional measures are necessary. The Basis of Review provides that buffers must be in undisturbed condition, except that drainage features can be located in the buffer if their construction and operation will not negatively impact the wetlands. The design drawings for Lots 245 and 247 demonstrate that the buffers are not undisturbed because fill will be placed in the buffer areas. There is no treatment system in place for the roads in Unit 11; thus, there is a potential for untreated runoff from the roads, which could contain oils, grease, and petroleum constituents, to reach wetlands or surface waters. The roads in Unit 11 are sometimes under water and will require increased maintenance to correct erosion from increased vehicular traffic. Road maintenance and grading present the potential to discharge sediment laden water into adjacent wetlands. This threat is particularly great in Unit 11 because many of the roads go directly through wetlands. The engineering calculations submitted by Royal Palm anticipate that the elevation of the roads will be raised. Raising the elevations will require additional fill, and because several roads in Unit 11 go through wetlands, additional filling of wetlands can be anticipated. Section 6.9(a) of the Basis of Review, requires that residential projects must have the calculated ability to discharge a sufficient volume of stormwater such that the system can return to the control elevation within 12 days of a design storm event. Royal Palm failed to provide information demonstrating that the storage volume provided by the systems proposed for the three lots can be recovered and therefore available for subsequent storm events. Without an adequate understanding of the functioning of the overall surface stormwater management system in Unit 11, it is impossible to determine the amount of time necessary for the systems on the three lots to bleed down to control elevation. In order to allow access to the three lots from the roads, fill must be placed in the roadside swales. Because the elevation of the roadside swales is below the seasonal high water table, they are defined as other surface waters. The swales are depressional areas that support an abundance of obligate wetland vegetation; thus, they are encompassed within the definition of jurisdictional wetlands. Thus, the project will involve direct impacts to wetlands.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered denying Royal Palm Beach Colony, L.P.'s application for No Notice General Permits for Lots 61, 245, and 237.

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

THE THREE PERMIT APPLICATIONS FDOT has applied to the District for a Wetland Resource Management (WRM) permit, a Surface Water Management (SWM) permit, and a Right of Way (ROW) occupancy permit. On June 6, 1994, the Applicant submitted applications for surface water management and wetland resource management permits for the purpose of widening and modifying this 20.4 mile stretch of U.S. 1. The surface water management permit application is identified as Application No. 940606-10. The wetland resource management permit application is identified as Application No. 940606-2-D. On October 24, 1995, the District issued Staff Reports on Permit Application No. 960606-10 and Permit Application No. 94060-2-D. These Staff Reports recommended issuance of the permits subject to general and special conditions as specified therein. An addendum to the staff report was issued November 3, 1995. On September 27, 1994, the Applicant submitted a request to modify its existing ROW Occupancy Permit to enable it to replace the bridge where U.S. 1 crosses the C-111 Canal. The land encompassed by the ROW occupancy permit challenged in this proceeding is located in Section 16 and 17, Township 59 South, Range 39 East, Dade County, Florida. A draft right-of-way occupancy permit with standard limiting and special conditions was produced as part of a package that went to the Governing Board and others. The proposed authorization for use of the ROW is for the following: REMOVAL OF EXISTING U.S. HIGHWAY 1 BRIDGE AND REPLACEMENT WITH A NEW FIXED BRIDGE. PROJECT INCLUDES CONSTRUCTION OF A NEW SERVICE/ACCESS ROAD, 2 DETENTION PONDS, 2 CATCH BASINS, 2-15" R.C.P. OUTFALLS, BOAT RAMP WITH LOADING DOCK, PARKING AREA, PEDESTRIAN GATE AT S-197, FENCING AND WILDLIFE CROSSING ALL WITHIN THE NORTH AND SOUTH RIGHT OF WAY OF C-111 (STATION 938+00 - 955+00). The draft right-of-way occupancy permit modification, identified as “SFWMD PERMIT NO. MOD 2548," should correctly be identified at “SFWMD PERMIT NO. MOD 2584.” The numbers “8” and “4” were inadvertently transposed. STIPULATIONS AS TO APPLICABLE LAW The parties have accurately set forth the applicable permitting criteria and the appropriate Basis of Review in their prehearing stipulation. CRITERIA FOR ROW PERMIT Rule 40E-6.301, Florida Administrative Code, provides, in pertinent part, as follows: In determining whether an occupancy permit should be issued, the District shall consider whether the proposed activity: interferes with the present or future construction, alteration, operation or maintenance of the works of the District; is consistent with the policy and objectives of Chapter 373 F.S., the legislative declaration of policy contained in Section 373.016, F.S. and the state water policy, Chapter 17-40, F.A.C.; has an actual or potential negative impact upon environmentally sensitive areas, which include: wetlands; endangered or threatened species habitat; aquatic preserves; outstanding Florida waters; federal, state and privately owned parks and wildlife management areas; designated areas of critical state concern; lands purchased by federal, state and local governments for the purpose of environmental protection, water resource protection and esthetics; and lands which contain native terrestrial plant species in significant amounts. Environmentally sensitive areas include areas on and off- site that are affected by activities which occur on, or are initiated from, the District’s works; degrades water quality within the receiving water body or fails to meet the provisions of Ch. 373, F.S., the state water policy, and Ch. 40E, F.A.C.; involves a discharge of wastewater from a new wastewater source or an increased discharge from an existing wastewater source; will discharge debris or aquatic weeds into District lands or works or cause erosion or shoaling within the works of the District; is supported by financial assurances, which will ensure that the proposed activity will be conducted in accordance with Chapter 373, F.S., and Chapter 40E-6, F.A.C.; presents an increased liability risk to the District; meets the general and specific criteria in the Basis of Review which is incorporated by reference in Rule 40E- 6.091, F.A.C.; interferes with actual or potential public use of the District’s works or public, recreational or other facilities not within the District’s works; is consistent with local zoning and other private land uses in the area; interferes with the quality or quantity of a public or private water supply; meets applicable criteria in Chapters 40E-61 and 40E-62, F.A.C.; ROW occupancy permits typically have standard limiting conditions which are incorporated as part of the permit. The permit may also have special limiting conditions. CRITERIA FOR PERMITTING THE SWM SYSTEM Rule 40E-4.301(1), Florida Administrative Code, contains the following criteria that, at the times pertinent to this proceeding, were used by SFWMD in determining whether to permit a surface water management system: In order to obtain or modify a permit under this chapter, an applicant must give reasonable assurances that the surface water system: provides adequate flood protection and drainage, without causing over- drainage, will not cause adverse water quality and quantity impacts on receiving waters and adjacent lands regulated pursuant to Chapter 373, F.S., will not cause discharges which result in any violations, in surface waters of the state, of the standards and criteria of chapter 17-302, F.A.C., will not cause adverse on-site or off-site impacts on surface and groundwater levels and flows, including impacts to sources of water supply and wetland hydrology, will not cause adverse environmental impacts, can be effectively operated and maintained, will not adversely affect public health and safety, is consistent with the State Water Policy, chapter 17-40, F.A.C., for a DRI with a signed Preliminary Development Agreement with the Florida Department of Community Affairs, pursuant to section 380.06(8), F.S., provides a surface water management system for that portion of the site approval for development which is able to operate separately from the surface water management system for the balance of the project site and still meet applicable District criteria. meets any applicable basin criteria in chapter 40E-41, F.A.C., will not otherwise be harmful to the water resources of the District, will not interfere with the legal rights of others as defined in subsection 17-40.401(8), F.A.C., is not against public policy, will meet general and specific criteria in the document described in subsection 40E-4.091(1)(a), F.A.C., (0) will meet criteria for isolated wetlands, which are found in Appendix 7 of the document described in rule 40E- 4.091(1)(a), F.A.C., (p) will meet the criteria for above ground impoundments, which are found in Appendix 6 of the document described in rule 40E-4.091(1)(a), F.A.C. The SFWMD has adopted certain procedures and criteria contained in a document, referred to as “Basis of Review for Surface Water Management Permit Applications Within The South Florida Water Management District” (BOR). Subsection 40E-4.091(1)(a), F.A.C. incorporates this document by reference into Chapter 40E-4, F.A.C. The BOR is a document that is “described in subsection 40E-4.091(1)(a), F.A.C.,” within the meaning of Rule 40E-4.301(1), F.A.C. The BOR establishes a rebuttable presumption that water quality criteria are met through specified volumetric retention and detention requirements. These performance based criteria are designed to be flexible. CRITERIA FOR THE WRM PERMIT In 1992 DEP entered into an Operating Agreement with the District, which delegated to the District responsibility for issuing wetland resource management (WRM) permits, which are required for dredge and fill activities in wetlands. Both DEP and the District implement the same wetland resource permit and MSSW permit rules. The District agrees with DEP's interpretation and application of the WRM permitting rules and non-rule policy, and applies the same when issuing such permits. Section 403.918, Florida Statutes (1991), provides the pertinent criteria that must be applied by the District in determining whether to grant or deny the WRM permit. That criteria requires the applicant to provide reasonable assurance that water quality standards will not be violated. In addition, for projects in OFW, the applicant must provide reasonable assurance that the project is clearly in the public interest. THE PUBLIC INTEREST TEST The District is required to balance the following criteria, found at Section 403.918(2)(a), Florida Statutes (1991), in determining whether a project is clearly within the public interest: Whether the project will adversely affect the public health, safety, or welfare or the property of others; Whether the project will adversely affect the conservation of fish and wildlife, including endangered species, or their habitats; Whether the project will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the project will adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; Whether the project will be of a temporary or permanent nature; Whether the project will adversely affect or will enhance significant historical and archaeological resources under the provisions of s.267.061; and The current condition and relative value of functions being performed by areas affected by the proposed activity. MITIGATION If the applicant is unable to otherwise meet the public interest test, the District shall, pursuant to Section 403.918(2)(b), Florida Statutes, “consider measures proposed by or acceptable to the applicant to mitigate adverse effects which may be caused by the project . . .” The District thereafter re-evaluates the project to determine whether the project, as mitigated, meets the public interest test. The criteria for mitigation is found in Chapters 373 and 403, Florida Statutes, Title 40 E (including the Basis of Review) and Rule 62-312, Florida Administrative Code. Rule 62-312.330, Florida Administrative Code, states the general criteria for evaluating mitigation proposals as follows: The goal of the mitigation proposal shall be to offset the expected adverse impact of the project that have resulted in the project being deemed unpermittable such that the resulting project with mitigation is not contrary to the public interest or, in the case of Outstanding Florida Waters, is clearly in the public interest. Each project must be separately evaluated to determine whether the proposed mitigation is sufficient. Rule 62-312.340, Florida Administrative Code, provides guidelines that are to be used in evaluating proposed mitigation projects. GENERAL DESCRIPTION OF THE PROJECT AREA FDOT proposes to widen a 20.4 mile portion of U.S. 1 in southern Dade County and northern Monroe County. Approximately seven miles of the project area is in Monroe County and approximately thirteen miles is in Dade County. The northern terminus of the project is the intersection of U.S. 1 and Card Sound Road, which is located in Dade County south of Florida City. The southern terminus of the project is the intersection of U.S. 1 and Abaco Road on Key Largo in Monroe County. The corridor of the proposed project passes through Sections 6, 7, 16, 18, 21, 27, 28, Township 59 South, Range 39 East; Sections 24, 25, 36, Township 58 South, Range 38 East; Sections 16, 19, 30, 31, Township 58 South, Range 39 East, Sections 16, 30, 31, Township 60 South, Range 40 East; Sections 25, 26, Township 60 South, Ranges 39 East, Dade and Monroe Counties, Florida. U.S. 1 is the main highway between northern Monroe County and southern Dade County. The only other road between Monroe County and Dade County is Card Sound Road. The Florida Keys is designated as an Area of Critical State Concern, pursuant to Section 380.0552, Florida Statutes. The Dade County portion of the road, north of the C- 111 canal, lies within typical Everglades habitat, which is classified as environmentally protected lands of Dade County. Most of the project corridor in Dade County is part of or adjacent to the Everglades National Park. Valuable wetlands exist throughout the project corridor. The following bodies of water will receive discharges if the surface water management system is permitted: C-111 Canal, Jewfish Creek, Lake Surprise, Blackwater Sound, Barnes Sound, Little Blackwater Sound, Long Sound, Manatee Bay, Sarge Lake, andManatee Creek. The receiving bodies of water are Outstanding Florida Waters (OFWs) or are connected to OFWs. THE EXISTING ROADWAY As it presently exists in the project area, U.S. 1 is a two lane undivided highway with two passing zones that are each one mile in length. Each travel lane on the existing facility is twelve feet wide. The existing shoulder on either side of the road consists of four feet of pavement and six feet of grassed area. FDOT Exhibit 7 accurately depicts the existing roadway typical section. Exotic vegetation, generally limited to the areas immediately adjacent to the highway, exist throughout the project corridor. These exotic species are present because FDOT has failed to properly maintain its right of way. A clear zone is an unobstructed area that includes the shoulder of the roadway and typically extends beyond the shoulder. The purpose of the clear zone is to provide a driver who has lost control of his or her vehicle a sufficient clear recovery area to regain control of the vehicle so that it can be maneuvered back onto the road. The clear zone for the existing road is inadequate to provide a safe recovery area. There is at present a two lane bridge over Manatee Creek, a two-lane bridge crossing the C-111 Canal, a bascule bridge, which is a drawbridge, over Jewfish Creek, and a two lane causeway through Lake Surprise. The two existing passing zones are located in Dade County. The first is south of U.S. 1’s intersection with the C-111 canal between mile markers 113-115. The second passing lane is approximately four miles south of the northern terminus of the project between mile markers 120-122. Each existing passing zone is undivided and consists of two northbound lanes and two southbound lanes, with each travel lane being twelve feet in width. The shoulders in the passing zones are the same as for the typical section. A surface water management (SWM) system is defined by Rule 40E-4.021(5), Florida Administrative Code , as being "the collection of devices, improvements or natural systems whereby surface waters are controlled, impounded, or obstructed.". There is no surface water management system presently associated with the road. The roadbed is elevated approximately five feet above mean sea level according to the National Geodetic Vertical Datum and was constructed on the old railroad bed of the Florida East Coast Railroad. No hydrologic culverts have been placed within the roadbed. Consequently, surface water flow between the eastern and western sides of the road north of the C-111 Canal has been cut off. C-109 AND C-111 CANALS In the 1960's, the C-109 and C-111 canals were constructed as part of an overall water management system in the area. As a result of the roadbed and the canals, water has been impounded on the western side of U.S. 1 at a level higher than on the eastern side. Due to cutoff of waterflow by the roadbed embankment, historic freshwater flow between the eastern and western sides of the project area has been restricted, which has resulted in an adverse impact on the Everglades ecosystem north of the C-111 Canal. The restricted water flow has resulted in less fresh water being available for shorter periods of time. Consequently, aquatic life has had reduced opportunities to develop. The restricted flow also has impeded the ability of aquatic life to reach freshwater areas during times of drought. On the east side of the road marine conditions have displaced what naturally should be freshwater conditions. PROJECT HISTORY While FDOT has been aware of traffic safety and hurricane evacuations concerns on the roadway for a long time, the current project originated in 1986 when Monroe County identified this project as a need in its 1986 Comprehensive Plan. Pursuant to agency practice, the proposed project was incorporated into FDOT's five year work program and a study was performed pursuant to FDOT’s Project Development and Environment (PD&E) Manual. FDOT's PD&E manual describes the process by which FDOT determines whether to construct or improve a road. The PD&E process includes an Environmental Impact Statement (EIS) to analyze existing conditions, assess the need for improvement, and develop alternatives. A Draft EIS is performed and circulated for comment to governmental agencies and the public. Based upon comments and further review a Final EIS is prepared. Metric Engineering ("Metric") began the PD&E study of the project in 1988 pursuant to a contract with FDOT. Metric identified seven factors which it concluded supported the need for the project. First, the improved corridor would improve the linkage between the four lane road at the northern terminus and the four lane road at the southern terminus. Second, the project would improve navigation by replacing the existing bascule bridge at Jewfish Creek. Third, the project would improve the level of service for the road. Fourth, the project would improve the safety of the road. Fifth, the project would improve the clearance time for hurricane evacuation. Sixth, the project was consistent with the long range transportation plans adopted by Monroe County. Seventh, the project would accommodate increased traffic, which can be expected with or without the project. Based on the needs evaluation, Metric performed a corridor analysis to determine the best way to get from Florida City to Key Largo, including improving only Card Sound Road, improving only U.S. 1, or improving a combination of the two. Metric concluded that the best resolution was to improve the project corridor. Metric also analyzed various alternatives in an effort to reduce the size of the typical section of the roadway in the U.S. 1 corridor and thereby minimize environmental impacts of the project. Because of concerns from Everglades National Park that no aspects of the project construction occur within its boundaries, FDOT agreed to conduct all construction east of FDOT's existing right of way line. The conclusions of the Metric studies were memorialized in a Final EIS and Final Engineering Report published in 1992. Conclusions regarding alternatives and project needs were then incorporated into the permit application and have continued to be updated. The 1992 version of the project was for a four lane roadway with four lane bridges throughout the project corridor. Subsequent to its June 6, 1994, permit applications to the District for a four lane roadway, FDOT went through an extensive process of providing the District with additional information in an effort to provide the District with the necessary reasonable assurance that the proposed project would comply with the permit criteria. The final series of modifications contained the three lane alternative, which will be described in detail below and is now the subject of this proceeding. The three lane proposal is a compromise that FDOT agreed to in an effort to minimize the direct, secondary, and cumulative impacts of the project. Monroe County passed Resolution No. 315-1995 on September 7, 1995, asking FDOT to build a three-lane road on a four-lane embankment. This resolution provided, in part, that “. . . Monroe County finds that the '3-lane alternative' as described in the Statement of Agency Commitments is the most viable proposal of those considered, because it balances the needs for a widened highway with safeguards designed to address secondary impacts.” The secondary impacts referred to in the resolution included concerns that two southbound lanes would result in more growth. The rationale behind the resolution was that more growth would result from two southbound lanes than from one southbound lane with the proposed passing zones. In response to the request of Monroe County and in response to a similar request made by the District, FDOT notified the District by letter dated September 5, 1996 of FDOT's decision to redesign the project to change the roadway from four to three lanes. FDOT HAS MINIMIZED THE IMPACTS OF THE PROJECT During the PD&E process prior to permit application FDOT studied project needs and alternative alignments, and conducted corridor analyses. FDOT originally considered a proposal that included approximately 250 acres of wetlands impacts. At the District's suggestion, FDOT revised its proposal prior to the permit application to reduce the wetland impacts and project footprint. The application submitted contained approximately 165 acres of impact. FDOT changed the typical section of the proposed roadway again after substantial interagency coordination in an effort to reduce wetlands impacts even further. FDOT agreed to reduce the footprint by changing the design of the median from 22 feet and a Jersey barrier (which is a minimum barrier) to 20 feet with a tri-beam rail barrier. The more substantial barrier was added because the median was narrowed. Additionally, instead of ten-foot paved shoulders on each side of the median, FDOT would use two-foot paved shoulders with sixteen feet of grass in the middle. These minimization efforts resulted in a wetland impacts decrease from 164 acres to 149.07 acres, the current impact of the project. Avoidance, or choosing alternate routes to avoid impacts to wetlands, was not a possible option because only wetlands and open waters exist between the northern and southern terminus of the project. FDOT explored all reasonable alternatives to the proposed project, including a two lane alternative proposed by a consultant for FBII. As discussed below, FDOT did not adopt the two-lane alternative, because the alternative did not address all of FDOT's identified needs for the project. FBII prepared a report with a two-lane alternative to the proposed project. FBII's original proposal included one 12-foot northbound lane with a 10-foot paved shoulder covered with thermoplastic rumble strips to deter vehicular use of the shoulder. In the southbound direction, FBII proposed a 12-foot travel lane with a 4-foot paved shoulder, essentially the same as currently exists. That proposal was analyzed by Metric Engineering on behalf of FDOT. FDOT rejected the FBII alternative for several reasons. First, though the 10-foot northbound shoulder theoretically may be used by cars during hurricane evacuation, removal of the rumble strips would be impractical due to lack of time to do so under threat of a hurricane, and due to the costs involved. It would be unrealistic to require people to otherwise drive over the rumble strips, without removal, because they are designed to prevent such access. Using the 10-foot shoulder during an evacuation would result in there being no shoulder area to remove accident vehicles from the roadway which would otherwise threaten to restrict the flow of traffic or cease it altogether. The reduced width of the shoulder lane below the standard 12-foot lane would also decrease the flow of evacuees. FBII's proposal for a two-lane fixed-height bridge at Jewfish Creek would not completely eliminate rear-end collisions at the bridge. The two-lane alternative proposed by FBII is not a signed and sealed cross section. The proposal by FBII does not include the area necessary for a SWM system or for clear zones. FBII did not do an analysis to determine whether its proposal complies with pertinent FDOT roadway and traffic design standards or with pertinent highway safety and improvement standards. The FBII proposal does not account for removal of the Lake Surprise causeway or construction related impacts from barge traffic. FBII did not do a wetlands survey to determine the impact of its two-lane proposal. At the Final Hearing, Petitioners presented for the first time a new proposal to use "flexible diverters" to pave a third northbound lane and to block that lane from travel traffic with poles. However, no research was conducted into the feasibility of such a proposal, nor was it adequately thought out. Such a use of "flexible diverters" is unprecedented in FDOT's history, is impractical to implement, and would violate FDOT's design standards contained in its Manual on Uniform Traffic Control Devices. Petitioners also presented for the first time at the Final Hearing a proposal to add an 8 to 10 foot paved northbound shoulder which could be converted to a travel lane with traffic control cones in the event of an evacuation. This plan is also not feasible, because the resulting lanes would not be wide enough to safely accommodate evacuating traffic, and because the contradiction between existing road striping and the placement of cones would likely cause accidents, which would halt evacuation. The proposals submitted by FBII do not sufficiently improve hurricane evacuation or traffic safety and, consequently, are not acceptable alternatives to the project. FDOT can do nothing else to minimize the impacts of the project and still address the needs for the project. Minimization of wetlands impacts was accomplished to the greatest extent possible. FDOT has proposed mitigation to offset the impacts that could not be avoided. THE PROPOSED PROJECT - IN GENERAL STIPULATION AS TO DESIGN AND CONSTRUCTION Petitioners stipulated that the design and construction specifications of the roadway proposed to be permitted in this case comply with all applicable design and construction standards for structural integrity, and adequately describe the three-lane divided roadway proposed to be constructed on a four-lane roadbed/embankment. PROPOSED LANES, SHOULDERS, AND MEDIAN FDOT proposes to widen the roadway in the project area to a three lane divided roadway with two northbound lanes and one southbound lane, plus three passing zones. The proposed project will be constructed on a four lane roadbed embankment. FDOT does not presently have plans to add the fourth lane to this roadway. FDOT Exhibit 8 contains an accurate description of the proposed typical section of the roadway. The typical section will consist of two twelve-foot northbound lanes with a six-foot paved shoulder and a four foot stabilized area adjacent to the paved shoulder; a twenty-foot median consisting of a two-foot paved shoulder, sixteen feet of grass and a tri-beam guardrail in the middle as a separator; and one twelve-foot southbound lane with an eight-foot paved shoulder. The proposed typical section also includes a storm water management system that will be described in more detail below. The proposed typical section includes a clear zone thirty feet in width, which is adequate. THE THREE PASSING ZONES The existing passing zone located in Dade County between mile markers 113 and 115 is one mile in length. FDOT proposes to alter this passing zone to 1.44 miles in length. The existing passing zone located in Dade County between mile markers 120 and 122 is also one mile in length. FDOT proposes to alter this passing zone to 2 miles in length. In addition, FDOT proposes to construct a 1.5 mile long passing zone between mile markers 110 and 112 in Monroe County. If permitted, the proposed project will include 2 passing zones in Dade County and 1 passing zone in Monroe County, for a total of 3 passing zones. The total length of the passing zones will equal 4.94 miles. ELEVATION There are no plans to change the elevation of the existing roadway. HYDROLOGIC CULVERTS The project contemplates the construction of 25 hydrologic culverts north of the C-111 Canal. These culverts will remain capped until further hydrological studies are completed and input from all concerned regulatory agencies can be obtained. It has not yet been determined how these culverts will be utilized to maximize the improvement to the ecosystem north of the C-111 Canal. WILDLIFE CROSSINGS INCLUDING THE C-111 BRIDGE The project contemplates the construction of three wildlife crossings north of the C-111 Canal in Dade County with fencing designed to funnel wildlife through the crossing. These crossing, sometimes referred to in the record as “panther crossings” are located between mile markers 118-119, 122-123, and 126-127 and will be constructed as overland bridges. In addition, the replacement bridge over the C-111 Canal (located between mile markers 116-117 in Dade County) is intended to serve as a wildlife crossing and will also employ fencing to funnel wildlife through the crossing. All four of these structures will be constructed as four-lane bridges, but will be striped for three lanes with rumble strips on the southbound fourth lane to discourage vehicular traffic in that lane. There will be an eight foot outside shoulder. FDOT proposes to construct 18 culverts south of the C-111 Canal for crossings by crocodiles, alligators, manatees, and other wildlife. These crossings will consist of 15 box culverts and 3 bridges. MANATEE CREEK BRIDGE The proposed bridge at Manatee Creek would be constructed as a four lane bridge, but would be striped for three lanes with rumble strips on the southbound fourth lane to discourage vehicular travel in that lane. There would be an eight foot outside shoulder. BRIDGING JEWFISH CREEK AND LAKE SURPRISE Jewfish Creek, which is part of the Intracoastal Waterway, and Lake Surprise would be bridged by a continuous structure. The Jewfish Creek bascule bridge would be replaced by a high-level four-lane fixed bridge. The Lake Surprise causeway would be replaced by a low-level four-lane bridge. The total distance for this bridging is approximately 2.35 miles. AREA OF PROJECT THAT WILL BE OPERATED WITH FOUR-LANES The three passing lanes (4.94 miles) and the bridge over Jewfish Creek and Lake Surprise (2.35 miles) would be operated with four lanes. Those areas total 7.29 miles of the 20.4 mile project corridor. Approximately 43 percent of the proposed roadway would have four lanes of pavement. Excluding the areas where the fourth lane will be blocked from travel with rumble strips, only 35 percent of the completed project will contain four travel lanes. This area consists of the three passing zones and the bridges over Jewfish Creek and Lake Surprise. THE PROPOSED SWM SYSTEM The proposed project would provide for a SWM system consisting of inlets, culverts, swales, berms and dry/wet retention areas. For the typical roadway section, runoff from the paved roadway surfaces will be directed to roadside swales designed to provide retention for 50 percent of 2.5 inches times the impervious area. The SWM system for the bridges will collect runoff in inlets and culverts and direct it to either swales or dry or wet retention ponds. The berms of the SWM system provide additional protection by restricting spills of pollutants, such as petroleum from overturned tankers or other vehicle accidents, from running into the surrounding waters. The berms and swales of the SWM are designed to catch pollutants and prevent their discharge into the surrounding waters. FDOT Exhibit 18 consists of four separate drainage reports submitted to the District in 1995 in connection with the project, one report for each section of the project. The reports accurately document the drainage calculations, the drainage design, the rationale behind the drainage design, and compliance of the design with the laws and regulations of the permitting agencies for the original four-lane proposal. On or about September 5, 1995, FDOT submitted revised drainage calculations to the District, determining the amount of stormwater treatment for the three-lane project. The revised calculations established that at least 95% percent of all stormwater runoff from the project would be captured in the proposed SWM system. Because the swale design was based on the originally proposed four-lane road, retention will be in excess of the required volume for most sections of the roadway. The required retention volume for this project is approximately 166 percent of what is required by the BOR. The surface and subsurface geology of the roadway consists of Miami oolite limestone overlain with Perrine maral. Underlying this is Thompson formation, anastasia and Key Largo limestone. Based on these constituencies, the swales proposed by the SWM system would be effective in rapidly removing heavy metals and phosphorous. The revised calculations established that approximately five percent of the project area will not have a SWM system. These areas will not have a SWM system because properly-sized retention systems in those areas can not be constructed without causing a disproportionate, adverse impact to surrounding wetlands. FDOT has provided reasonable assurances that the proposed SWM system’s total water quality treatment exceeds the District's permitting requirements and provides sufficient treatment to exceed the BOR requirements. The water discharged from the proposed system would be of higher quality than that currently discharged, which is not treated. FDOT has provided reasonable assurances that the proposed SWM system complies with the permitting criteria found in Rule 40E.301(1)(a)-(p), Florida Administrative Code. The following findings are made as to that criteria. Rule 40E-4.301(1)(a), F.A.C. The parties stipulated that Rule 40E-4.301(1)(a), F.A.C., pertaining to flood protection and the adequacy of drainage, is not at issue in this proceeding. Rule 40E-4.301(1)(b), F.A.C. The quality of water being discharged from the SWM system will be of substantially higher quality than the existing discharges. Consequently, it is concluded that the system will not cause adverse water quality impacts within the meaning of Rule 40E-4.301(1)(b), F.A.C. In addition, the evidence established that there will likely be less water discharged from the roadway if the project is constructed because of the amounts of water that will likely be retained in the swales that are a part of the SWM systems. Rule 40E-4.301(1)(c), F.A.C. Because the receiving bodies of water are designated Outstanding Florida Waters, the District is required to apply the DEP's most stringent water quality requirements -- the antidegredation requirements for discharge to OFWs, to this project. Those standards will be discussed in more detail below. The evidence established that the proposed project will not violate those requirements. Rule 40E-4.301(1)(d), F.A.C. Impacts to sources of water are not at issue. The District reviewed the potential effect of the SWM system upon on-site and off-site impacts to surface or groundwater levels and flows. The evidence supports the District's conclusion that no adverse impacts will be caused. Petitioners failed to present any evidence on groundwater levels and flows. Consequently, it is found that the criteria found at Rule 40E-4.301(1)(d), F.A.C., has been satisfied. The 25 hydrologic culverts north of C-111 have the potential to re-establish historic surface water flow in the area. They were sized, based on rainstorm events, to help equalize water levels from one side of the road to the other. The culverts are capable of transferring water from west to east to assist in the historic restoration of flows. In order to assure the proper usage of the culverts, they will remain gated until the District develops a management plan in conjunction with other agencies. The District will determine the maintenance entity. The FKAA water main runs beneath this section of the road. As a result, there is no other more hydrologically efficient alternative for the placement of the culverts. The culverts would also provide a means for overwash from storm events, over the U.S. 1 roadbed, to flow back to its point of origin, stabilizing the roadbed and allowing release of the accumulated salt water. Rule 40E-4.301(1)(e), F.A.C. In addition to providing for a net improvement in water quality, the project will offset any adverse impacts through mitigation and other environmental enhancements for which no mitigation credits are being assigned, as described below. Rule 40E-4.301(1)(f), F.A.C. FDOT has a history of adequate maintenance of SWM systems, and has provided reasonable assurance that it has the staff and budget to comply with District operation and maintenance requirements. FDOT will also be able to comply with the District's requirements to control exotic plants and other foliage along project corridor. Rule 40E-4.301(1)(g), F.A.C. The SWM system will not adversely affect public health and safety. The dispute as to the public interest test focused more on the WRM permitting requirements. Findings as to the public interest test are discussed in more detail below. Rule 40E-4.301(1)(h), F.A.C. The evidence established that the SFM system is consistent with State Water Policy. Rule 40E-4.301(1)(i), F.A.C. This project does not pertain to a DRI and, consequently, this criteria is not applicable. Rule 40E-4.301(1)(j), F.A.C. There are no basin criteria applicable to this project. Rule 40E-4.301(1)(k), F.A.C. The evidence established that the SWM system will not be harmful to the water resources of the District. While there will be adverse environmental impacts caused by the project, those adverse impacts have, as will be discussed in more detail below, adequately offset by mitigation. Rule 40E-4.301(1)(l), F.A.C. This issue was not at issue in this proceeding. Rule 40E-4.301(1)(m), F.A.C. As will be discussed in greater detail in a subsequent section of this Recommended Order, the project is not against public policy. For the reasons set forth in that subsequent section, it is found that the project is clearly in the public interest. Rule 40E-4.301(1)(n), F.A.C. Rule 40E-4.091(1)(a), F.A.C., constitutes the BOR. As discussed in detail above, the SWM system complies with the BOR. Rule 40E-4.301(1)(o), F.A.C. There are no isolated wetlands pertaining to this project. Rule 40E-4.301(1)(p), F.A.C. There are no above ground impoundments, as described in Appendix 6 of the BOR, pertaining to this project. WATER QUALITY - DISCHARGES INTO OFW Because the project will involve discharges into Outstanding Florida Waters, it was necessary for FDOT to establish that the discharges from the SFW system will not degrade those OFWs. The evidence established that FDOT's proposed project complies with and exceeds applicable water quality standards and permitting criteria. There will be no significant degradation of ambient water quality as a result of the project. It is expected that there will be a net improvement in ambient water quality resulting from the proposed project, as opposed to the continued degradation if nothing is done to treat stormwater runoff. In FDOT Exhibit 46, FDOT provided baseline water quality data in the form of STORET data for waters adjacent to the project area. STORET is a centralized repository and database for water quality data throughout Florida. It is Florida's principal source of water quality data. STORET contains the best scientific database on water quality in Florida. The STORET data set forth in FDOT Exhibit 46 provided sufficient evidence on ambient water quality for the waters adjacent to the proposed project. In addition to providing the water quality data in FDOT Exhibit 46, FDOT is required by Special Permit Condition 37 to submit appropriate water quality data in the surrounding waters prior to any construction activities. SFWMD Exhibits 5 and 6 contain amendments to Proposed Agency Action made after the beginning of the formal hearing. These amendments include a requirement that an appropriate water quality monitoring plan be submitted within 30 days of the permit issuance. FDOT has provided reasonable assurances that water quality standards will be met and that there will be appropriate water quality monitoring during construction. DIRECT IMPACTS OF THE PROJECT The proposed roadway design will result in the following direct impacts to wetlands adjacent to the roadway corridor: 1) the dredging of 11,028 cubic yards of material from 2.1 acres, 2) the placement of 1,689,553 cubic yards over 147.0 acres of wetlands, and 3) 6.9 acres of (potential) permanent impact due to shading and 4.1 acres (potential) of temporary impacts from the Jewfish Creek Bridge construction activities to seagrass habitat. In order to determine the project's direct impacts, the area surrounding the project was surveyed to determine the number of affected acres. This was done by using a computer aided design ("CAD") system, and by categorizing the various forms of wetlands and associated flora and fauna into the following communities: mangrove, emergent freshwater, open water, and tidal, consisting of seagrass and non-vegetated bottoms. Using these categories and the CAD system, every square foot of direct impacts were accounted for. The adverse direct wetland and surface water impacts of this project are as follows: 1) 27.83 acres Non- Vegetated Tidal Bottom; 2) 11.27 acres Seagrasses; 3) 46.85 acres Mangroves; 4) 42.35 acres Sawgrass/Cattail/Spikerush; 5) 14.31 acres Shrub Wetlands; and 6) 6.46 acres Open Fresh Water; totaling 149.07 acres. Though some wetlands to be impacted may be of lesser quality, FDOT stipulated that all wetlands to be directly impacted by the project should be considered to be high quality wetlands for the purpose of mitigating the impacts. The impacted wetlands are part of larger wetland systems. Petitioners assert that the District should have required studies as to impacts as to the larger wetland systems. The evidence established that the District appropriately considered the type and location of the wetlands involved so that additional study suggested by Petitioners was unnecessary. Petitioners also assert that impacts to isolated wetlands should have been studied. The evidence established that there will be no such impacts. SECONDARY AND CUMULATIVE IMPACTS RECOGNIZED BY SFWMD In addition to the direct impacts of the project, the District is required to analyze secondary and cumulative impacts. A project's secondary impacts are those that, though outside of the project footprint, are very closely linked and causally related to the project. This is a "but for" test. Secondary impacts are those impacts which, if not for the proposed project, would not occur. Both positive and negative secondary impacts are considered. When there are both positive and negative secondary impacts caused by a project, the permitting agency must consider the severity of the impacts and balance these together with the other factors in the public interest test to determine whether or not the project is clearly in the public interest. WRM statutes, and DEP rules and policies pertaining to those statutes do not regulate growth or traffic increases, per se. Only if such increases are very closely linked and causally related to the project will they be considered. The District identified several secondary impacts that would be temporary in nature since they would occur while the project is being constructed. One is the use of a barge facility, primarily at Jewfish Creek, where the anchoring of the barge may result in temporary impacts to seagrass during construction. This impact is addressed by a component of the seagrass mitigation at Boca Chica, discussed below. Another impact is turbidity associated with the dredge and fill and the barge activities. That issue is appropriately addressed by permit conditions, through the use of turbidity control screens and other techniques. The District also identified secondary impacts directly associated with the project footprint that would be permanent in nature. The removal of the exotic vegetation potentially opens up the areas adjacent to the road north of the C-111 canal to off-road vehicles or four-wheel driving and the potential impacts caused by those vehicles. That impact is appropriately addressed by fencing north of the C-111 canal. When a road is widened, animals have a greater distance to travel back and forth from one side of the road to the other. A wider road exposes such animals to greater risk of being hit by a motor vehicle while crossing the road. That impact is addressed in this project by the fencing, the wildlife crossings, and the wildlife box culverts. The crossings are designed for large mammals and some species, such as the Indigo snake, will likely not use these crossings. The wildlife crossings will not entirely mimic the crossing patterns of all wildlife that need to cross U.S. 1 and will result in some wildlife habitat fragmentation. The fencing that will be erected to funnel wildlife through the crossings will fragment the habitat of some species by altering wildlife crossing patterns and blocking access of some species to certain areas of habitat. The greater weight of the evidence established that any habitat fragmentation should, when compared to existing conditions, be minimal. The District appropriately evaluated the advantages and disadvantages of using wildlife crossing and hydrological culverts and appropriately concluded that there would be a net benefit to wildlife as a result of their construction. The District properly concluded that the culverts, bridges and fencing located south of the C-111 canal, construction of wildlife crossings and fencing north of the C- 111 canal, construction of the hydrologic culverts, and removal of the Lake Surprise Causeway are positive secondary benefits of the project. These benefits should be considered when applying the public interest test. THE FKAA PIPELINE RELOCATION The project requires the relocation of two segments of the existing pipe owned by the Florida Keys Aqueduct Authority (FKAA) around Jewfish Creek Bridge. The segments total approximately 1.5 miles. The District inspected the area where the pipeline will be relocated to assist in determining its impact. The pipeline relocation is a temporary disturbance during construction. It is a small linear facility, which will not generate pollution in and of itself. The pipeline relocation is not expected to result in a violation of State water quality standards. The FKAA is responsible for obtaining the necessary permits for the relocation. Direct impacts to wetlands will occur in a 4 to 5 foot wide strip along the length of the relocated aqueduct. The FKAA has submitted a permit application to the DEP for a permit to relocate the aqueduct. DEP believes that adequate mitigation can be achieved to make the project permittable. Once the FKAA submits an adequate mitigation plan, then relocation of the aqueduct will not be an adverse secondary impact caused by the U.S. 1 project. The permit for the subject project should contain a condition that the FKAA obtain a permit for the relocation of these two segments of its pipeline. THE C-111 BOAT RAMP There is an existing boat ramp designed for small boats to access District canals that is located on the north side of the C-111 canal. As a result of the proposed project, it will be relocated to the southern side of the project. This relocation is a relatively minor project requiring a cut in the canal bank and a fourteen-foot wide slab for the boat ramp. When the District considered the potential impacts associated with this relocation in conjunction with the impact of the proposed project, it was determined to be a relatively insignificant impact in terms of the project as a whole. Relocation of the boat ramp is not expected to result in a violation of state water quality standards. All direct, cumulative, and secondary impacts, whether positive or negative, should be considered in balancing the public interest test. ARE THERE ADDITIONAL SECONDARY AND CUMULATIVE IMPACTS Petitioners assert that there are additional cumulative and secondary impacts that the District failed to consider. Petitioners argue that the project cannot meet permitting criteria if those additional impacts are considered. The additional impacts pertain to additional development throughout Monroe County because of the “rate of growth ordinance” (ROGO), additional development along the project corridor, impacts to the coral reefs of the Keys, impacts to Key Deer, generalized impacts, and impacts from increased number of “day trippers." For the reasons discussed below, it is found that the District has considered all appropriate direct, secondary, and cumulative impacts of the project. The additional impacts that Petitioners assert should have been considered are not causally connected or directly linked to the project. THE RATE OF GROWTH ORDINANCE Monroe County adopted its Year 2010 Comprehensive Plan (the "Plan") to meet the requirements of Chapter 163, F.S. The Plan, adopted May 15, 1993, is unusual in that the County limits future growth based on a carrying capacity analysis of its hurricane evacuation clearance time. No other jurisdiction in Florida, and few others in the United States, have used a carrying capacity planning approach. To implement the carrying capacity limitation, Monroe County determined the total number of dwelling units that could be permitted while maintaining an acceptable hurricane evacuation clearance time of 24 hours. This number of dwelling units, less an allowance for vested development and development in municipalities, was the basis for a ROGO that was adopted by the County in 1992. The ROGO allocates the available units at a uniform annual rate of growth (currently, 255 units per year). The ROGO regulates all proposed new residential buildings, including hotels, motels, and other transient tourist accommodations as well as permanent residences. The number of building permits that Monroe County can issue is, at present, directly related to how rapidly the County can be evacuated in the event of a hurricane. The lower the clearance time, the greater the number of permits that can be issued. The Comprehensive Plan requires that the County be able to evacuate within a 24-hour period. As of March 7, 1995, the hurricane evacuation time for Monroe County was determined to be 21.25 hours.1 The project is expected to reduce by six or seven hours the modeled hurricane evacuation capacity for Monroe County, regardless of whether it consists of three or four lanes. This is because both the three lane and four lane plans provide for two northbound lanes. Because of the rate of growth provisions in county law, this reduction of clearance times results directly in an increase in the number of building permits that the county can issue annually. Under ROGO, Monroe County can, with this project, issue 255 permits each year through the year 2026. Without this project, Monroe County can issue 255 permits each year only through the year 2001. Alternatively, without this project, the county can issue 88 permits each year through the year 2010 if it chooses to issue permits over a longer period of time. Following extensive litigation before the Division of Administrative Hearings in an unrelated proceeding2, the Administration Commission entered a final order on December 12, 1995, that approved approximately 97 percent of the Plan. In addition, the Administration Commission has published a proposed rule to bring the remainder of the Plan into compliance and assure its financial feasibility. The central feature of the proposed rule is a five- year work program, with annual reviews by the Administration Commission. It is likely that the proposed rule will eventually result in the complete revision of the ROGO. The proposed rule provides that Monroe County's annual rate of growth be revised within five years, no later than December 31, 2001, "to establish a rate of growth and a set of development standards that ensure that any and all new development does not exceed the capacity of the county's environment and marine systems." A carrying capacity study will comprehensively assess water quality, habitat protection, and public facility issues to determine the capacity of the Keys to sustain further development. The proposed project is but one of many factors that will be considered in future rate of growth regulations. If the expected revisions occur, it would be speculative to predict what development would be allowed. While the studies are underway the rate of growth will remain at 255 units per year. The rate of growth will be reviewed annually, and may be reduced a minimum of 20% if the goals of the studies are not being met. The DCA has determined that Monroe County’s Comprehensive Plan and its land development regulations are sufficient to prevent or mitigate any potential adverse secondary impacts of the project caused by development. The DCA has consistently supported the proposed project, even in its earlier four-lane configuration, because it was consistent with Monroe County's 1986 Comprehensive Plan, and because the project would improve hurricane evacuation clearance times and improve water quality in the vicinity of the roadway. The 1986 plan supported widening of the roadway to four lanes based on projected travel demand. The DCA prefers the current, three-lane proposal to the earlier four-lane. On September 7, 1995, the Monroe County Commission adopted Resolution 315-1995 in support of the proposed project because "it balances the needs for a widened highway with safeguards designed to address secondary impacts." Lorenzo Aghemo, an expert in comprehensive planning, served as Monroe County Planning Director during the development of the Plan and ROGO. In Mr. Aghemo's opinion, the widening of the roadway to either three or four lanes would generate minimal growth pressure in Monroe County, particularly because the Plan limits the rate of growth. Because the Keys are designated by Section 380.0552, F.S., as an area of critical state concern, the DCA is charged with oversight of Monroe County's Comprehensive Plan, its LDRs, and all development that takes place in Monroe County. Additionally, the Administration Commission may amend Monroe County's plan or regulations by rule (See Section 380.0552(9), F.S.). There is virtually no action that Monroe County can take related to the use of land without review and approval of a state agency. The Administration Commission’s proposed rule demonstrates its intent to revise comprehensively Monroe County's ROGO within five years to ensure that future development does not exceed the capacity of the Keys' environmental resources. It also demonstrates the Administration Commission's intention to closely monitor growth and development in the Keys during the five-year study period. Some of the studies required by the proposed rule are already underway: 1) the DCA has entered into a contract with the ACOE to complete the environmental carrying capacity study; 2) the HRS study of advanced on-site waste water treatment systems is underway; 3) Monroe County is developing the required Marathon central sewer facilities plan; and 4) Monroe County and HRS have begun the cesspit identification and elimination process. Caution should be exercised in relying on this or on any other proposed rule. Likewise, caution should be exercised in relying on changes to ROGO that may or may not occur. It is likely that the present status of the law will be changed in the near future so that future development will be based on environmental carrying capacity as opposed to hurricane evacuation clearance times. However, for the purposes of this proceeding the District should accept the fact that the issuance of future building permits is closely linked and causally related to the project. Consequently, it is found that under the present status of the law, the issuance of additional building permits in Monroe County is closely linked or causally related to the project. MONROE COUNTY LDRS AND DCA OVERSIGHT Although Petitioners established that there is a causal relation between the project and the existing status of the law governing the number of building permits that can issued in the future, the evidence was insufficient to establish at a level above speculation that adverse environmental impacts will result because of the issuance of those building permits. The Monroe County Comprehensive Plan contains land development regulations that govern all development in Monroe County. These regulations are among the most stringent in the State and are designed to avoid or minimize adverse environmental impacts caused by development. All development orders in Monroe County are closely scrutinized by the Department of Community Affairs to ensure compliance with applicable permitting criteria. Those regulations and the DCA’s close scrutiny are intervening factors that break any causal relation between the project and the speculative adverse environmental impacts that the Petitioners assert will be caused by future issuance of building permits by Monroe County. Petitioners failed to establish that the impacts of future development are very closely linked or causally related to the project. Consequently, it is found that such impacts are not secondary or cumulative impacts of the project. DEVELOPMENT ALONG THE PROJECT CORRIDOR A major portion of the area next to the road has little or no development potential because it is either water, land in public ownership, or land slated for public ownership. The areas east of the road are mostly in private ownership, but are primarily submerged lands and mangrove areas. The Crocodile Lakes National Wildlife Refuge is federally owned and is managed by the U.S. Fish and Wildlife Service (USFWS). The Southern Glades lands, located immediately west of the project and Everglades National Park (ENP) in Dade County, have been acquired by the District and are managed by the Florida Game and Freshwater fish Commission (FGFWFC). The Model Lands Basin in Dade County is in private ownership but proposed for public acquisition in the future. The land adjoining the roadway in Dade County is designated as open area or environmentally sensitive. Almost half of the land along Monroe County's portion of the roadway is in public ownership. At least 90% of the land in private ownership is mangroves or wetlands that cannot be developed. The small area of uplands is currently being used by a resort marina which will not be allowed to develop further under the new comprehensive plan. There is very little potential for future development in the project area. The comprehensive plan designation for areas in Dade County are open space, and the ones in Monroe County have the conservation designation. The District's regulatory programs consider areas adjacent to the project as sensitive wetland habitats. Based on the District's regulatory authority and comprehensive plan designation for those lands, which would have to be obtained prior to obtaining a permit for development, it is very unlikely that those lands could be developed. Florida Rock and Sand Co. (FRS) has a permit to mine approximately 1,100 acres of wetlands. As part of its mitigation program, FRS will donate this land to the District once its mining and mitigation projects are complete. The FRS mitigation lands are preserved as a permit condition and will ultimately be transferred to the District. This land will not be developed. In addition, the District established that the U.S. 1 project and the FRS project do not constitute a cumulative impact that the District failed to consider. The evidence established that development along the project corridor will not be a secondary or cumulative impact of the project. IMPACTS ON CORAL REEF SYSTEM The evidence was insufficient to establish a close link or causal connection between the project and the coral reef system. As reflected elsewhere, it is found that there will be no degradation of ambient water quality as a result of the project. Therefore, there is no need to resolve the conflicting testimony as to the present status of the coral reef system. IMPACT ON KEY DEER There are no key deer in the project area. The nearest key deer habitat, Big Pine Key, is approximately 70 miles from the southern terminus of the project. The evidence is insufficient to establish that there is a very closely linked and causally related connection between the project and key deer mortality on Big Pine Key. GENERALIZED IMPACTS The Petitioners presented certain opinion testimony that the Keys cannot be developed in an environmentally sensitive manner because of potential adverse impacts of new development in Monroe County, or new boats operating in the waters of the Florida Keys. The credibility of that testimony need not be evaluated because the evidence was not sufficient to tie those generalized concerns into the specific regulatory criteria of the permitting agency. There was insufficient evidence to establish that those alleged impacts would be very closely linked or causally related to the proposed project. DAY TRIPPERS Induced demand is new travel that occurs solely because additional capacity is added to a highway. Petitioners' transportation experts, Michael Replogle and Robert Morris, testified that FDOT's traffic studies, and FDOT's projected rate of traffic growth of approximately 3 percent annually, are incorrect because the studies do not predict the amount of "induced demand" that would result from the proposed project. Petitioners assert that induced demand would generate an unknown number of people who drive to the Keys for the day from south Dade County, referred to as “day trippers,” will have an impact on the Keys that has not been evaluated. The assertion that this potential impact has not been analyzed is rejected as being contrary to the greater weight of the evidence. Induced demand is accounted for in Monroe County's Long Range Transportation Plan, which was never evaluated by Mr. Replogle or Mr. Morris. The Long Range Transportation Plan was prepared by an experienced traffic engineering consulting firm, Barton-Aschman, using an FDOT- approved traffic demand model, the FSUTMS model, that includes all traffic generators and attractors, and all travel on U.S. 1 on weekdays and weekends. The FSUTMS model does not restrict demand based on the existing road capacity. The model uses an "unrestrained assignment" that incorporates the total predicted trip generation on recreational facilities, hotels, and all other attractors. The Long Range Traffic Plan was used to develop the Monroe County Comprehensive Plan, which takes into consideration the projected increases in traffic and makes appropriate provisions for those increases. FDOT has provided reasonable assurances that it has properly projected the amount of traffic for the project corridor after the project is completed and that the projected increases have been appropriately addressed by Monroe County's Comprehensive Plan. MITIGATION - IN GENERAL For the reasons discussed above, it is found that there are no secondary or cumulative impacts that the District failed to consider. Petitioners also contend that the mitigation proposal is insufficient to offset the direct and secondary impacts recognized by the District. This is a large dredge and fill project that will permanently fill 149 acres of wetlands. The wetlands that will be adversely impacted by the project include OFWs that provide a great variety of functions and serve as habitat for fish and wildlife, including threatened and endangered species. The wetlands are unique and of high quality. Mitigation for direct, secondary and cumulative impacts was considered as part of the permit evaluation. In- kind mitigation is considered to be most effective, but out- of-kind mitigation may be offered by the applicant where it is impractical to conduct in-kind mitigation due to historic changes in the project area or sensitivity of the habitat type for which mitigation is offered. Such mitigation is also appropriate to address regional alteration of an ecosystem, such as the Everglades ecosystem alteration caused by the original roadway embankment. FDOT developed a conceptual mitigation plan that took into account project impacts on the freshwater, marine and estuarine components of the ecosystems involved, as well as the impacts on threatened and endangered species of wildlife which may be affected by the project. FDOT coordinated the plan's development with the National Parks Service, U.S. Fish and Wildlife Service, the Army Corps of Engineers, the National Marine Fisheries Service, the U.S. Environmental Protection Agency, the Dade County Department of Environmental Resources Management, the Florida Game and Fresh Water Fish Commission, and the Florida Department of Environmental Protection. The conceptual mitigation plan evolved as a result of project modifications and agency comments into what is now proposed as mitigation for the project. The current proposal is summarized in FDOT Exhibit 26, consisting of Attachment H to FDOT's SWM and WRM permit applications. The timing of their construction falls into two general categories: mitigation previously permitted and concurrent mitigation. UPFRONT MITIGATION Typically, mitigation is done concurrently with project construction rather than prior to permit issuance. Mitigation is often done afterwards because of construction timing constraints. Here, FDOT applied for and, in May 1994 received, permits to conduct mitigation prior to applying for the permits at issue, with the understanding that performance of these activities does not require the District to issue permits for the proposed projects. A total of 385.22 acres of mitigation has already been completed. The applicant received 203.02 mitigation credits from the District on May 12, 1994, for several mitigation projects that the applicant proposes to apply to the proposed U.S. 1 widening project provided it is approved. Table 2 of Attachment H to FDOT Exhibit 26 sets forth the four mitigation projects that constitutes the up- front portion of the mitigation for the project. This table sets forth the acres mitigated, the conversion factor for the mitigation, and the resulting mitigation credit awarded. The four mitigation activities already authorized are: enhancement of the wetland habitat in the Harrison Tract located adjacent to Barnes Sound within the Crocodile Lakes National Wildlife Refuge on the north end of Key Largo (70.37 acres credit for 252.6 acres of restoration); removal of the spoil mounds on the eastern bank of the C-111 canal east of U.S. 1 located on the District’s ROW (10.65 acres credit); the back filling of the C-109 canal levee located on the District ROW within the Southern Glades Save Our River project (112.7 acres credit); and the removal of the roadside spoil mounds on the west side of U.S. 1 located between C-111 and the Dade Work Camp Road within the District’s Southern Glades Save Our Rivers Project (9.30 acres credit). The mitigation projects pertaining to the roadside spoil removal along U.S. 1, the backfill of the C-109 Canal, and the removal of spoil along the C-111 Canal are similar projects because they each involve existing deep ditches cut through wetlands. When these deep ditches were cut, the spoil material from the ditch was deposited alongside the ditch. This resulted in areas that were previously Everglades wetlands becoming spoil, supporting the growth of exotic species and, for the most part, not exhibiting wetland functions. FDOT is proceeding with the backfilling the C-109 canal located between mile markers 122.5 and 117, and removal of the corresponding spoil mounds created during construction of the C-109 canal. In connection with this mitigation, marsh areas, tree islands and deep water aquatic refugia have been restored. In this area, there has been considerable attraction of wildlife subsequent to restoration, including otters, alligators, and turtles, which could not previously use the habitat because the canal was too deep. Upon completion waterflow between the east and the west will be restored, and the area will be restored to a wetland habitat from its current uplands habitat type. Backfilling of the C-109 canal is part of an interagency effort with the ACOE to restore as closely as possible to natural conditions the flow of water in the C-111 watershed area. C-111 mitigation includes removal of roadside spoil along the C-111 canal to restore the natural condition of the area. The mitigation was devised in coordination with the National Maine Fisheries Service (NMFS), which required mitigation for non-vegetated habitat types. Restoration also includes preserving some spoil areas as islands to maintain habitat for endangered species of plants. When the C-111 spoil mounds are scraped down, the fill will not fill the whole ditch. The ditch will, therefore, be a bit more valuable but will not be completely restored to its former elevation. FDOT will also remove roadside spoil along the west side of U.S. 1, upon which exotic species of plants had grown, and returning the area to its original grade. The Harrison Tract is a known habitat and nesting area for American crocodiles. Its wetlands functions were altered or eliminated by prior development of the land by its original owners. Restoration includes regrading the area to restore its original wetlands functions, including habitat for young and adult crocodiles. FDOT's mitigation of the Harrison Tract also includes restoration of tidal flushing to increase contributions of nutrients and food sources to the surrounding tidal bay system. Crocodiles have been observed using the restored areas. FDOT has installed additional nesting berm habitat, basking habitat and shallow lagoon habitat to promote juvenile crocodile development. The District established that the credit awarded for this mitigation and the conversion ratios utilized for determining this credit were consistent with agency practice and its pertinent rules. FDOT was given a 1:1 credit ratio for areas involving full restoration of wetlands. In other portions of the Harrison Tract mitigation involving restoration of flushing to existing wetlands, FDOT was given not full credit, but credit based on the severity of limitation of the existing wetland functions. Based on this evaluation, mitigation credits were given in a range of a 3:1 ratio for restoration of severely disrupted or non-existent wetlands to a 20:1 ration for restoration of higher quality but not fully functional wetlands. FDOT is being awarded 70 mitigation credits for the 252 acres in the Harrison Tract that are being restored or enhanced. CONCURRENT MITIGATION Based on the mitigation ratios developed by the District, additional mitigation credits were required. Consequently, the project contemplates mitigation that will be undertaken concurrently with the construction of the project in addition to the upfront mitigation. FDOT proposes to earn these additional credits by projects involving creation and/or restoration of emergent vegetation, mangrove and seagrass habitats. FDOT’s proposal to mitigate mangrove impacts with "out of kind" mitigation of emergent vegetation habitats was viewed by the District as being necessary and appropriate because there were no sufficiently large areas of mangrove habitat suitable for restoration. Table 7 of Attachment H to FDOT Exhibit 26 sets forth the four mitigation projects that constitutes the concurrent portion of the mitigation for the project. This table sets forth the acres mitigated, the conversion factor for the mitigation, and the resulting mitigation credit awarded. In addition, the table references certain credit for the placement of the hydrological culverts. As will be discussed later, that credit was withdrawn at the formal hearing. The four mitigation activities that will constitute the concurrent portion of the mitigation plan are: the removal of the Lake Surprise causeway (2.90 acres credit); the scrape down of the Jewfish Bridge approaches (0.67 acres credit); the restoration of the FGFWFC road (10.34 acres credit); and the Boca Chica project (27.17 acres credit) The Lake Surprise Causeway removal mitigation involves 5.26 acres of on-site seagrass restoration and 0.54 acres of unvegetated bottom mitigation through the excavation of 52,220 cubic yards of material. Lake Surprise historically was a shallow tidal lake supporting seagrasses before a causeway was built across the lake over the seagrasses. FDOT proposes to remove the causeway and restore the previous elevation, after which it is anticipated that seagrasses that grow on the east side of the causeway will fully recruit naturally to the excavated area. Removing the Lake Surprise Causeway will establish 5.26 acres of seagrass, for which FDOT received 2.63 acres of on-site mitigation credit based on a 2:1 ratio. Through natural recruitment after removal of the causeway, there is a high likelihood that the entire 5.26 acres will recolonize with seagrass. FDOT minimized the seagrass impacts to the greatest extent possible. The mitigation credit pertaining to Lake Surprise does not include credit for the removal of the causeway itself. This awarded credit is for the restoration of seagrass areas. The mitigation pertaining to the Jewfish Creek Bridge approaches proposes the scrape down of 1.33 acres of existing fill to allow the area to become recolonized with mangroves. Boca Chica is located in southern Monroe County over one hundred miles from the southern terminus of the project. This site was chosen by FDOT as a site for seagrass mitigation project after FDOT reviewed several other potential sites. Two other sites were rejected. The area around the C- 111 canal was rejected because the land proposed for use was in private ownership. Several defunct marinas in Port Bougainville were rejected due to poor conditions not conducive to seagrass growth. Boca Chica was finally chosen as the site because it was a large enough area with light and hydrological flow conditions conducive to seagrass growth. The evidence establishes that the Boca Chica site is the most viable for seagrass mitigation. The seagrasses to be impacted at Lake Surprise are healthy and productive turtle grass, manatee grass and cuban shoalgrass. Turtle grass is considered an extremely valuable “climax community” of seagrasses which hold sediments in place, cleanse water quality, and forms the base of the food chain. It is valuable to sea turtles, manatees and recreationally important fish and shellfish. The cuban shoalgrass that will colonize at Boca Chica is a pioneer colonizer species that grows in disturbed areas. It is not as valuable to the marine system as turtle grass. The Boca Chica seagrass mitigation permit condition proposed to offset impacts to 11.27 acres of seagrass. This will involve the removal of 306 cubic yards of sediment and hydraulically dredging approximately 1,175 cubic yards of spoil material. The proposed permit conditions state that FDOT shall provide future maintenance of the culvert areas to maintain adequate flushing. FDOT will plant 25.92 acres of seagrasses to mitigate for the remaining 8.64 acres of impacts, for a mitigation ratio of 3:1. In addition, 8.46 acres of seagrass will be planted to mitigate for the barren bottom area that will be affected, and 1.62 additional acres will be planted to compensate for any unexpected impacts to Boca Chica based on the necessary improvements. Overall, there will be of 36 acres of seagrass mitigation by FDOT, for which FDOT is receiving 27.17 acres credit. FDOT will also increase the water flow between the east and west lagoons of Boca Chica, and maintain the culverts connecting the two sides, in order to further promote growth of seagrass therein. FDOT is responsible for 80% survival of each acre of seagrass mitigation, as well as monitoring once a year for five years. Based on historical data obtained from Boca Chica during past mitigation efforts, there is a high likelihood that the entire 36 acres of mitigation will survive, and that the remaining 74 acres of the Boca Chica lagoons will experience natural recruitment of seagrass as a result of FDOT's efforts. The FGFWFC access area was built by excavating a ditch, and putting fill on the wetlands and creating a dirt road bed. After the C-109 canal is backfilled, the access road will no longer be needed. The mitigation project will excavate the existing road bed, back fill it into the ditch, thereby recreating the wetlands that were there previously. FDOT will receive 10.34 mitigation credits based on a 1:1 ratio of acres restored. EVALUATION OF MITIGATION There is no mitigation in this permit for any wetland impact beyond the direct loss of the specific 149 acres that will be dredged or filled. Mitigation was provided only for the direct, footprint impacts of the project. None of the up front mitigation involves the creation of wetlands, which entails converting areas that were not previously wetlands or open water and turning them into wetlands. It will likely take between 20 and 50 years for the mitigation areas to achieve full functional value required by the South Florida Water Management District mitigation permit. In the interim, there will be a net loss of wetland functional value. With time, the proposed mitigation has a high likelihood of success. Based on FDOT's past successes in mitigation of construction-related impacts, FDOT is able to comply with permit conditions relating to best management practices associated with the construction of bridges and pilings and turbidity screens around road construction, as well as restoration of seagrasses and mangroves. Petitioners assert that the District erred in determining the credit to be given for the up-front portion of the mitigation. While it is true that the SFWMD Rules do not mention "up-front" mitigation, the District has the authority to consider all aspects of a mitigation project in weighing its relative value. Consulting engineering inspectors have been retained by FDOT to insure that all permitting requirements are met during mitigation and construction, and that the technical special provisions for protection of threatened and endangered species are complied with by FDOT. The proposed permits contain appropriate conditions that require FDOT to monitor and maintain the mitigation areas. FDOT will be responsible in perpetuity for maintaining the tidal flushing connection at the Boca Chica mitigation site. Special permit condition 6 to the SWM and WRM staff reports require wetland and upland monitoring. If wetland and upland monitoring or other information demonstrate that additional adverse impacts have occurred due to this project, FDOT would be required to offset the loss of any additional wetland impacts. MITIGATION IS APPROPRIATE The evidence established that the mitigation projects were fairly and appropriately reviewed by SFWMD and that the mitigation credits were fairly and appropriately awarded. The evidence also established that there is appropriate mitigation for the direct, secondary, and cumulative impacts of this project. ACTIVITIES NOT RECEIVING MITIGATION CREDIT Mitigation credits for the 25 hydrologic culverts north of C-111 were originally included in the permit staff reports. Those mitigation credits were removed in an addendum to the staff reports, introduced as District's Exhibits 5 and 6. These credits were not necessary to offset project impacts. After the staff report was issued, they became a point of contention by the Petitioners because they will not be utilized until a management plan is developed. Since they were not necessary to meet mitigation requirements, the credits were removed from this project. These credits were never included in the mitigation ratios for these permit applications. The addendum removed the 9.6 credits initially contemplated for the culverts. No credit has been awarded for the relocation of threatened and endangered species of plants, such as Joewood and Bay Cedar by FDOT from the C-111, C-109 and roadside spoil mitigation areas. These species have been relocated to tree islands constructed by FDOT on the mitigation sites, or to other areas that would not be impacted by the project. FDOT also was not given mitigation credits for: (1) the wildlife crossings and the fencing that will funnel wildlife through these crossings; (2) installation of pipe culverts north of the C-111 canal and bridges and box culverts south of C-111; and which, in addition to providing a corridor for aquatic species, will increase the tidal flushing of the area; (3) the removal of the Lake Surprise Causeway, which will restore historical hydrological flow between the eastern and western sides of Lake Surprise; (4) FDOT's commitment to improve and maintain the flushing of the west lagoon culverts in Boca Chica (mitigation is in the east lagoon); and (5) FDOT's contribution of $300,000 to assist Monroe County in performing a carrying capacity study for the County. Additionally, FDOT will preserve the Jewfish Creek Bridge abutment, which will be preserved for local historical purposes. FDOT will prepare the Jewfish Creek Bridge pilings for an artificial reef at Long Key during construction. THE PUBLIC INTEREST TEST It is appropriate for the SWFMD to consider, in balancing the public interest test, to consider traffic safety and hurricane evacuation.3 Because of FDOT's expertise in those areas, it is appropriate for the permitting agency to give great weight to highway safety concerns, including hurricane evacuation, presented by FDOT. The application of the public interest test does not involve consideration of non-environmental factors other than those expressly set forth in the statutes such as navigation or preservation of historical or archaeological resources. Specifically, aesthetics, quality of life, the potential for a project to cause increased crime, and school overcrowding are not properly considered within any of the seven factors contained in Section 403.918(2)(a), Florida Statutes (1991). The District concluded that the project is clearly in the public interest based upon consideration and balancing of the following factors: hurricane evacuation improvements, public safety improvements, a SWM system where no SWM system currently exists; wildlife crossings and fencing north of the C-111 canal where no such crossings or fencing currently exist; wildlife box culverts to accommodate crocodiles, alligators, manatees and marine life where no such culverts currently exist; and hydrologic culverts, which have the potential to assist in the restoration of hydrologic flows, and the mitigation projects, both upfront and concurrent. SECTION 403.918(2)(a), FLORIDA STATUTES Section 403.918(2)(a), Florida Statutes, requires the permitting agency to determine “[w]hether the project will adversely affect the public health, safety, or welfare or the property of others." The property of others is not at issue. As discussed below, the evidence clearly established that the project will greatly enhance the safety of the road during normal operations and facilitate evacuation in the event of a hurricane. There will be clear benefits to the public safety as a result of this project. As part of the PD&E process, FDOT, through Metric, prepared "A Safety Evaluation" of the existing roadway. The safety analysis was based on FDOT accident statistics for the years 1983-1988, as well as engineering review of the conditions causing the accidents. Specifically, FDOT based their safety analysis on the following: 1) calculation of the abnormally high accident rate on the roadway based on the rate quality control formula set forth in the FDOT Highway Safety Improvement Guidelines, and approved by the Federal Highway Administration; 2) copies of the actual crash reports filed with the Florida Division of Highway Safety and Motor Vehicles, which provided detail greater than that generally available through FDOT's own accident data reports, and which formed the basis of the collision diagram in the Safety Evaluation (FDOT Exhibits 36; and 3) and its August 1996 update thereto (FDOT Exhibit 41), on-site evaluation and review of the roadway to determine geometrics of the roadway, locations of driveway accesses and side roadways and the degrees at which roadways intersected. Metric prepared an update of the Safety Evaluation for the years 1989-1994, to determine the continuing validity of the Safety Evaluation, as well as to review alternative proposals to the original proposed roadway configuration. In preparing the update, the recent accident data (FDOT Exhibit 37) and the underlying research in the Safety Evaluation were used by Metric Engineering in reaching its conclusions. The Safety Evaluation performed by Metric in 1989 established high accident rates on the roadway based on a detailed segmental analysis of the roadway. In August of 1996, the Safety Evaluation was updated by Metric, which update confirmed the findings of the Safety Evaluation, and further stated that accident frequency on the Monroe County portion of the roadway exceeded the state average accident rate and the abnormally high accident rate for the years 1990 through 1994 (notwithstanding the rear-end accidents occurring at Jewfish Creek). Fatal accidents on the Dade County portion exceed the state average on the same stretch by 37 percent for the same years. The most severe accidents occur on the Dade County portion. The Monroe County portion of the roadway exceeds the statewide average in the abnormally high accident rate four out of the last five years that FDOT studied. The Dade County portion does not exceed the accident frequency or the number of accidents, but the fatality rate in Dade County is much higher than the state average. Presently an abnormally high accident rate exists in three locations along the project corridor, two of which are in the vicinity of the Jewfish Creek bridge. The third location is north of the bridge on Cross Key. Replacing the Jewfish Creek Bridge with the fixed-height bridge proposed by FDOT will substantially increase the safety on the project corridor. The District considered this to be an important positive element in the public interest balancing test. The existing 2:1 slopes of the roadway make it difficult for drivers to recover from running off the roadway, resulting in a greater frequency of this type of accident. Moreover, the existing clear zone is not large enough to overcome the 2:1 slope to allow safe recovery of errant vehicles. As a result, catastrophic crashes occur rather than safe recoveries. Also, as with hurricane evacuation discussed in the following section, actual accidents on the roadway prevent traffic from accessing or leaving the Keys, and also prevent emergency vehicles from rapidly accessing the Keys and a crash site. This occurs because there is little or no shoulder or clear zone along the sides of the road to allow emergency vehicles to efficiently access an accident site, and in the event of a severe, head-on type collision, the roadway is blocked off. U.S. 1 through the project corridor is regarded as so unsafe for travel that Monroe County law enforcement officials call it "death alley." There are many head-on collisions due to the two-lane, no-median alignment. Law enforcement is difficult and dangerous along the roadway, because it has very few areas wide enough to allow law enforcement officials to detain driving violators. It is also very dangerous, for the same reasons, for a driver to pull off the roadway with a broken-down vehicle. High rates of speed and impaired drivers contribute to the accident rates along the project corridor. The efforts of law enforcement to control speeders and drunk drivers is impeded since it is practically impossible for enforcement officers to turn their vehicles around to pursue violators without running a high risk of causing an accident on their own. The project would significantly improve safety on the roadway by reversing the problems identified in the this section, as well as the previous sections of this Recommended Order. The project would virtually eliminate head-on collisions which largely contribute to serious injuries and fatalities along the roadway. The project would also help eliminate problems with emergency vehicle access to accident sites and restoration of service in the event of accidents, and would increase the roadway's level of service as discussed below. Improved level of service was an additional need considered by FDOT during the PD&E process. While the District did not consider the traffic level of service by itself to be weighted as part of the positive public interest criteria in this project, the impacts of resulting congestion are relevant to the public interest consideration of traffic safety as discussed in the foregoing sections. Lower quality level of service, as presently exists on the roadway through level of service F, adversely affects the safety of the roadway. When traffic levels rise, driver frustration increases leading to drivers passing in no-passing zones and potentially resulting in head-on collisions and high-severity accidents. Additionally, due to the narrow shoulders of the existing roadway, accident vehicles pose a threat to and impede normal traffic flow on the roadway. The Highway Capacity Manual set the standards for traffic engineering and is used in all fifty states. The manual classifies the existing roadway as a two-lane arterial rural road. Applying the standards for measuring level of service for two-lane rural roads set forth in the Highway Capacity Manual, FDOT determined that the existing level of service on the roadway is E, which is a very poor level of service that does not meet the established standard of level of service C required by the Highway Capacity Manual. Monroe County uses a speed based method of calculating level of service. Using that method, the level of service for U.S. 1 is at an acceptable level. The parties disagree as to which method of calculating the level of service is appropriate. That conflict is resolved by finding that the method used by FDOT is the appropriate method because of its wide acceptance and long-term use. Traffic volume in the area of the southern terminus of the project is growing at a rate average annual rate of 3.07 percent. In the present condition of the roadway, level of service will degrade to F, or forced-flow conditions, by the year 2006. Even with the improvements proposed by FDOT, the level of service in the northbound direction would improve to level of service B, but the level of service in the southbound direction would remain at level of service D or E due to the single southbound land configuration. Hurricanes pose a serious threat to the safety and welfare of residents and visitors of the Keys. Monroe County is the most vulnerable hurricane-prone area in the United States because it is surrounded by tropical waters, land elevation is low throughout the islands, and the evacuation routes are limited to U.S. 1, an extended route that starts in Key West and runs to the mainland, and Card Sound Road. The greatest potential for loss of life during a hurricane in the Keys is from storm surge. Storm surge is a dome of water near the center of a hurricane which is created by the winds on the water's surface. In a category 3, 4 or 5 storm, the entire land mass in the path of the storm will be inundated. Because of the wind and storm surge associated with hurricanes, the best response to a hurricane warning in the Keys is to evacuate people to the mainland away from the water and the storm surge threat. Accordingly, Monroe County orders a mandatory evacuation in a category 3, 4, or 5 hurricane, and no shelters are opened. There is little or no disagreement as to the vulnerability of the Keys to hurricanes or as to the danger posed by a hurricane. There is disagreement as to whether the proposed project is needed for improved hurricane evacuation. The conflicting evidence in this regard is resolved by the following findings, which are based on the more credible, substantial evidence. The existing road does not have sufficient hurricane evacuation capacity to meet the present and projected future needs of Monroe County residents and visitors. In current hurricane evacuations, the two northbound lanes on U.S. 1 between mile marker 90 and 106 are split at Key Largo. Sixty percent of the traffic is directed up the northbound lane of U.S. 1; forty percent of the traffic is diverted onto the northbound lane of Card Sound Road. One southbound lane of U.S. 1 and Card Sound Road must remain open for emergency vehicles to reach an accident or a disabled vehicle, or to bring emergency supplies into the Keys. Improving the roadway is critical to the success of Monroe County's hurricane evacuation plan. FDOT relied on hurricane evacuation and needs modeling performed by Monroe County and the ACOE to confirm the need for improvements. All of the models used indicated that the project corridor is the controlling roadway segment for improving hurricane evacuation of the Keys. Additionally, FDOT relied on the Lewis Report of January 15, 1993, a study commissioned by the Governor of Florida. Recommendation No. 17 of the Lewis report recommends that FDOT expedite the design and construction of the project, which is viewed as being critical for increasing the rate of emergency evacuation. Dr. Robert Sheets, former director of the National Hurricane Center, testified that the failure to make improvements to the roadway would be "unconscionable." Dr. Sheets and Billy Wagner, the Director of Emergency Management for Monroe County, presented very compelling and very persuasive testimony that this project is essential for hurricane evacuation purposes. The proposed project is the minimum transportation improvement that will achieve a significant improvement in evacuation safety and clearance time. With the present two- lane configuration and narrow shoulders, evacuating traffic would be halted completely by a vehicle breakdown or an accident blocking one lane. Replacement of the Jewfish Creek Bridge will also facilitate the hurricane evacuation need for the project. In addition to improving the rate of evacuation, the project will make an evacuation safer. Emergency personnel cannot reach accidents on the roadway during an evacuation because, in certain segments, no roadbed exists adjacent to the northbound lane. A second northbound lane and wider road shoulders would enable disabled vehicles to be serviced and removed from the highway. The proposed changes to the road would improve emergency vehicles' access to an accident scene. The elevation of the roadway at Lake Surprise is so low that it can be flooded easily by a storm. The proposed project would replace the existing muck bed of the roadway with more stable material. The existing roadway is subject to settling and washout during storm events, which reduce the safety of the roadway itself and reduce the evacuation capacity of the roadway. If washout occurs, moving equipment to the islands for recovery efforts following a hurricane will be difficult or impossible. The proposed project will prevent erosion and reduce the effects of storm surge and wave action on the road during a hurricane. When the project has been completed, three lanes of evacuating traffic, two lanes from U. S. 1 and a third from Card Sound Road, will converge at Florida City. Representatives of FDOT, the Monroe County Sheriff's Department, the Florida Department of Law Enforcement and Monroe County Emergency Management have planned to manage the northbound traffic when it reaches Florida City during an evacuation. Several feasible alternatives exist, but additional planning is needed to prevent a monumental bottleneck at the northern terminus of the project. While it is clear that this project will not resolve all problems that exist as to hurricane evacuation, it is also clear that this project is essential to improve hurricane evacuation. SECTION 403.918(2)(a)2, FLORIDA STATUTES Section 403.918(2)(a)2, Florida Statutes, requires the permitting agency to consider “[w]hether the project will adversely affect the conservation of fish and wildlife, including endangered species, or their habitats.” The District considered the effect of the direct loss of dredging and filling 149.07 acres of wetland. As set forth in previous sections, it is found that this loss will be offset by the mitigation. For use during construction of the project, FDOT will adhere to technical special provisions and special permit conditions 9 through 13 to protect manatees, crocodiles, alligators, indigo snakes, marine turtles, and valuable trees, palms and other wildlife, to minimize or preclude any impacts to those species. Additionally, any osprey nests around the Jewfish Creek Bridge area at the time of construction will be relocated by FDOT if necessary. As part of the development of the FEIS, as required by the Federal Highway Administration under the National Environmental Protection Act, FDOT obtained official letters of concurrence from the USFWS and NMFS that the project would cause no adverse impacts to endangered species under section 7 of the Endangered Species Act. That process also established the project's consistency with Florida Coastal Zone Management Program, as determined by the State Clearinghouse within the Office of the Governor, in coordination with DEP, the Department of National Resources and FGFWFC. The project also contains provisions to impact positively or enhance the conservation of fish and wildlife, including threatened or endangered species and their habitat, as described below. These were positive factors that further helped neutralize and offset the 149.07 acres of direct impacts. In addition, FDOT is required to evaluate the effectiveness of the fencing along the entire project corridor, discussed below, and report to the District on that effectiveness. If the District determines that the fencing could be more effective, it may require FDOT to implement those suggestions. South of the C-111 canal, construction of box culverts and bridges addresses impacts to the American crocodile, a listed endangered species. Problems were identified with placement of existing culverts, which did not provide enough clear space and which caused the crocodile to cross over the roadway rather than through the culvert. To address this problem, 15 larger box culverts and three bridges will be placed within the roadway. These provide the necessary clear space to allow the crocodile to safely pass under rather than over the road. The location of the box culverts was chosen by reviewing crocodile mortalities associated with road crossings. Placement of these box culverts and bridges will also improve the hydrological flow of water within the project area, provide a crossing area for manatees, and allow greater dispersal of the crocodile population throughout Florida Bay. Species expected to use these box culverts include aquatic and aquatic water dependent species in the area. They were primarily targeted for crocodiles, alligators, and manatees, but certain fishes, turtles, frogs and other species in the wetlands along the project corridor will utilize the culverts. The box culverts will have 100 feet of wingback fencing extending north and south of each culvert. The intent of the wingback fencing is to funnel wildlife into the box culverts. Intermittent or wingback fencing is appropriate south of the C-111 canal for two primary reasons. First, the animals which will be guided into the box culverts are aquatic dependent. The area south of the C-111 canal is primarily water, washed mangrove areas and tidal creeks. Crocodiles tend to move in tidal creeks. Second, it was not possible to ensure continuous fencing along all portions of the project south of the C-111 canal because there are existing businesses. It could not be assured that these businesses would keep a gate closed. The project originally proposed continuous fencing alongside the road where it abuts ENP. Continuous fencing was initially proposed because the initial application included a solid concrete barrier down the median of the road. If a crocodile did enter the road from the side with discontinuous fencing, after crossing one lane the crocodile would hit the barrier, but then easily find its way back to the area it came from. However, the project was later modified to include a tri-beam barrier because it lessens the footprint of the project and thereby lessens the wetland impact. Since the current application does not include a continuous barrier down the middle of the road, if a crocodile enters the road it would cross the tri-beam barrier, go across another lane of roadway before hitting a continuous fence. The animal would then run up and down that fence with nowhere to go except back across the road again. This would increase their exposure to a road kill. With the installation of bridges and culverts along the southern portions of the project corridor, there is no need for continuous fencing because aquatic wildlife, such as the American crocodile, will tend to follow the flow of water through the culverts rather than climb over the roadway. The FGFWFC and ENP oppose continuous fencing and prefer intermittent fencing south of C-111 canal since the project now includes a tri-beam barrier. Positive benefits also include construction of panther crossings at four locations north of the C-111 canal to account for impacts to the Florida panther, a listed endangered species, in the vicinity of the project, along with continuous fencing on both sides of the road north of the C- 111 canal. The crossings will be placed at locations that show historical use by wildlife, including areas at the Dade County Correctional Institute access roadway, the water control structure on the C-109 canal, and the berm of the C- 111 canal. The wildlife crossings are indicated by blue dots on FDOT's Exhibit 1. FDOT underwent years of extensive coordination with the environmental regulatory and resource agencies to design a project that would accommodate their ecosystem management plans. The location of the wildlife crossings was based upon radio telemetry data, collected from radio-collared panthers, and their typical corridor movement. The location was further chosen based on input from the USFWS and the FGFWFC. The continuous fencing north of the C-111 canal will prevent wildlife from crossing the road, and instead force them to use the wildlife crossings. The crossings were designed for panther use, the panthers being the shyest animal in the area. If panthers can be accommodated, then other threatened and endangered species and other wildlife are expected to use them. DOT studies of the effectiveness of wildlife crossings, with fencing, including crossings installed on Alligator Alley, establish that wildlife will use the crossings, both singly and in groups, and that the crossings substantially reduce, if not eliminate, automobile- related mortality of wildlife. Documented wildlife include panthers, wild turkeys, wading birds, alligators, deer, bobcats, black bears and raccoons. SECTION 403.918(2)(a)3, FLORIDA STATUES Section 403.918(2)(a)3, Florida Statutes, requires the permitting agency to consider “[w]hether the project will adversely affect navigation or the flow of water or cause harmful erosion or shoaling.” The replacement of the bascule bridge at Jewfish Creek with a 65-foot high fixed-height bridge will be a benefit to navigation. Because Jewfish Creek is part of the intracoastal waterway, the existing bridge has to be frequently raised or lowered to accommodate marine traffic. Because of the age of the existing structure, frequent breakdowns have been experienced. Marine traffic is stopped or delayed if the bridge cannot be raised or if there is a delay in raising the bridge. Vehicular traffic is stopped while the bridge is raised. Regarding the flow of water, the project incorporates wildlife box culverts and bridges, which will improve tidal flushing and the flow of water south of the C- 111 canal. The District considered this to be a positive consideration under the public interest test. The 25 hydrologic culverts north of the C-111 canal were also a positive factor in the test because the culverts provide future water management capability. Erosion and shoaling are neutral factors in the public interest test because the permit conditions contain a plan to control erosion and shoaling during construction and to provide for road stabilization after construction. In addition, there is a positive factor regarding shoaling in that the roadway area now has a lot of storm action, causing problems with erosion on the side of the road. The project provides for road stabilization, which is a neutral to positive factor in the public interest test. SECTION 403.918(2)(a)4, FLORIDA STATUTES Section 403.918(2)(a)4, Florida Statutes, requires the permitting agency to consider “[w]hether the project will adversely affect the fishing or recreational values or marine productivity of the project.” A positive factor pertaining to marine productivity is the box culverts and bridges south of C-111, which will allow marine species to travel beneath the road to access the water on both sides of the road. Removal of the causeway along Lake Surprise opens that water body back up to one contiguous system, which is also a positive factor. The seagrass mitigation addressed in previous sections will also improve marine productivity and provide habitat for fish. SECTION 403.918(2)(a)5, FLORIDA STATUTES Section 403.918(2)(a)5, Florida Statutes, requires the permitting agency to consider “[w]hether the project will be of a temporary or permanent nature.” The project is permanent, though some construction impacts are temporary in nature. Once temporary impacts have ended and the project is complete, the project will be a positive benefit, because of the construction of the SWM system, culverts, animal underpasses and other benefits as set forth above. SECTION 403.918(2)(a)6, FLORIDA STATUTES Section 403.918(2)(a)6, Florida Statutes, requires the permitting agency to consider “[w]hether the project will adversely affect or will enhance significant historical and archaeological resources under the provisions of s. 267.061.” This factor is not at issue. SECTION 403.918(2)(a)7, FLORIDA STATUTES Section 403.918(2)(a)7, Florida Statutes, requires the permitting agency to consider “[t]he current condition and relative value of functions being performed by areas affected by the proposed activity.” A percentage of wetlands immediately adjacent to the road are impacted by exotic vegetation. Areas further out are part of a significant wetland ecosystem and are considered high quality. This project contains an exotic control program within FDOT's right of way, which is a positive consideration in the public interest test. Wetlands are currently receiving untreated storm water, which runs off the road immediately into the adjacent wetlands and water bodies without treatment. The project will include a SWM system where none currently exists as is detailed in the previous sections. This is a positive factor in the public interest test. The direct impacts of the project on 149 acres of wetlands alongside the roadway is not as large or significant as the impact caused by placement of the original embankment and resulting cut off of the eastern and western portions of the Everglades north of the C-111 canal. Overall, the concurrent and upfront mitigation efforts of FDOT are of regional significance and benefit to Everglades ecosystem by helping to repair the damage caused by the original embankment. THE PROJECT IS CLEARLY IN THE PUBLIC INTEREST The District appropriately weighed all considerations in determining that the project is clearly in the public interest. The greater weight of the competent, credible evidence established that the project is clearly in the public interest. RIGHT OF WAY PERMIT APPLICATION The land encompassed by the ROW permit has been properly adopted as a "work" of the District, requiring District authorization via a ROW Permit Modification to FDOT. The District's real property interest in the C-111 ROW applicable to the ROW permit modification consists of both fee simple and easement interests. The evidence is clear that DOT's application for the permit modification was thoroughly reviewed by the District, consistent with the District's established ROW permit review process. The District presented uncontroverted evidence and expert testimony to establish by a preponderance of the evidence that issuance of the permit modification to FDOT is consistent with all applicable District statutes, rules and other criteria, including the District's conditions for issuance of ROW Permits set forth in Rule 40E-6.301, F.A.C. FBII offered no evidence or testimony to the contrary. FUTURE MODIFICATIONS Modifying the project at a later date to pave a second southbound lane would require a District ERP permit. The addition of impervious surface triggers the District's SWM jurisdiction in this regard. However, FDOT established that that it had no current plans for further widening. The permit conditions require secondary and cumulative impacts associated with the increased capacity be addressed in accordance with the rules and criteria in effect at the time of any application for future widening. In addition, the permits require that FDOT must comply with any more stringent water quality criteria in effect at the time of any future widening. MODIFICATIONS AT THE FINAL HEARING At the Final Hearing, the District issued an Addendum to Staff Report for each of the SWM and WRM permits. The amendments made non-substantive changes to the District's staff reports regarding fencing along the roadway, performance of a study of fencing on the roadway by FDOT, water quality sampling along the roadway, assignment of mitigation credits, and other technical changes in wording for purposes of clarification. The changes set forth in the District's Exhibits 5 and 6 do not create impacts to the environment beyond those addressed elsewhere herein.
Recommendation Based on the foregoing findings of fact and conclusions of law it is RECOMMENDED that the Governing Board of the South Florida Water Management District enter a Final Order that issues the three permits challenged in this proceeding (SWM Permit No. 940606-10, WRM Permit No. 9460606-2-D, and ROW Permit No. 2584) subject to the conditions contained in the staff reports on the SWM permit application and the WRM permit application and subject to the additional permit conditions reflected by District Exhibits 5 and 6 and by the Findings of Fact pertaining to the permit for the relocation of the FKAA pipe. DONE AND ENTERED this 11th day of April, 1997, in Tallahassee, Leon County, Florida. ___________________________________ CLAUDE B.

Findings Of Fact The Parties and the Property. The Respondent, HORNE, owns or has options to purchase approximately 24.35 acres of real property at the southwest corner of U.S. Highway 41 and State Road 50 Bypass in Brooksville, Florida. The Petitioner, the ASSOCIATES, owns approximately 67.5 acres of real property to the south and downstream from the HORNE property. The ASSOCIATES' property is presently undeveloped. The HORNE property contains an existing Publix shopping plaza, a mobile home sales office and vacant lands. The Publix plaza was previously permitted by the DISTRICT before it was constructed. The Surface Water Permit Application On August 7, 1992, HORNE submitted its application for surface water permit No. 400317.02. The application sought approval to construct a surface water management system for a proposed new K-Mart store on HORNE's property. On November 3, 1992, the DISTRICT issued notice of final agency action approving issuance of permit No. 400317.02 to HORNE. The day before the original final hearing in this matter scheduled for March 1993, new information from a study called the Peck Sink Watershed Study came to light which rendered the project as then designed unpermittable. This information resulted in the surface water management system being redesigned. On April 1, 1993, the DISTRICT notified all of the parties that the redesigned surface water management met District rule criteria. This resulted in issuance of what became known as the April 1 submittal. On May 12, 1993, in response to concerns raised by the ASSOCIATES at depositions on May 10, 1993, HORNE produced the May 12 submittal and provided it to all parties on that same date. The changes in design reflected on the May 12 submittal related to lowering the pond bottoms one foot below the orifices and changing the contour lines on the outside of Pond 5A. On May 13, 1993, further minor changes were made to the permit materials. Specifically, the changes were: reflecting on the engineering worksheets the lowering of the pond bottoms accomplished on the May 12 submittal, correction of the contour line on the outside of Pond 5A and showing the amount of additional fill into the 100-year floodplain caused by the addition of the contour line to the outside of Pond 5A. In reviewing HORNE's application, the District applied the standards and criteria set forth in Chapter 40D-4, Florida Administrative Code, and the Basis of Review for Surface Water Management Permit Applications. Compliance with DISTRICT Permitting Criteria Water Quantity The main two areas considered by the DISTRICT in assessing water quantity in a closed basin are: attenuating the peak rate of discharge for the 25 runoff for the 100 The peak rate of runoff for this project for the 25 (2) cubic feet per second (cfs) less in the post-developed condition than in the pre-developed condition, as shown on the April 1 submittal. No changes were made between the April 1 and May 12 or 13 submittals relating to the peak rate of discharge. The difference in the volume of runoff between the pre-developed and post-developed condition during the 100-year storm is being retained on site, as shown on the April 1 submittal. Therefore, DISTRICT rule criteria for the peak rate and volume of runoff were met on the April 1 submittal. Lowering the bottoms of the detention ponds on the May 12 and 13 submittals resulted in additional post 100 system, as redesigned to retain this additional 100-year volume, exceeds the DISTRICT's 100 Floodplain Encroachment Under the DISTRICT's floodplain encroachment standards, any fill within the 100 out an equivalent volume of fill elsewhere on the property. HORNE's application satisfies the DISTRICT's floodplain standards. HORNE is filling 1.59 acre feet of the floodplain and creating 1.75 acre feet of compensation. The floodplain compensation will be above the seasonal high water table, as required by Section 3.2.1.4 of the DISTRICT's Basis of Review. The original, existing seasonal high water table will be lowered as a result of the excavation so that the entire floodplain compensation area will be above the seasonal high water table. Water Quality A wet detention system as proposed by HORNE is an acceptable means under the DISTRICT's rules of treating runoff for water quality purposes. The bottoms of the ponds, as shown on the May 12 submittal, are all at least one foot below the orifice elevations, as required by the Basis of Review. Thus, the project met all relevant DISTRICT water quality requirements as of the May 12 submittal. Operation and Maintenance DISTRICT rules require that reasonable assurances be provided that the surface water management system can be effectively operated and maintained. HORNE will be the operation and maintenance entity for this surface water management system. The DISTRICT's main concerns at the time of permit review are that the design of the surface water management system not be an exotic design, that the design insure that littoral zones can be established, that the system orifice can be cleaned, that the overall system will be stable and that there is a viable operation and maintenance entity. HORNE's project can be effectively operated and maintained. Remaining District Rule Criteria As stipulated to by the parties that the project will not cause adverse impacts to wetlands and will not diminish the capability of a lake or other impoundment to fluctuate through the full range established for it in Chapter 40D Additionally, the proof establishes that the project will not cause adverse impacts on surface and groundwater levels and flows will not adversely affect the public health and safety; is consistent with the requirements of other public agencies; will not otherwise be harmful to the water resources within the District; will not interfere with the legal rights of others as defined in Rule 17 Objections Raised by the ASSOCIATES at the Hearing Pond Slopes and Operation and Maintenance Contrary to the assertion that the pond slopes will not be stable and cannot be effectively operated and maintained, the pond side slopes at this project are going to be constructed out of a heavy clay type of soil. Sodded side slopes of 1:1, as proposed for three of the ponds, can be stabilized and effectively operated and maintained. Although there is no DISTRICT requirement that sodded side slopes be mowed, so on these slopes could, if necessary, be cut. In the event the side slopes were to erode, easy repair is possible. All of the ponds except one side of one pond have areas at least 20 feet wide and slopes no steeper than 4:1 where maintenance can be performed. With regard to the pond that does not have this characteristic, equipment can enter and perform necessary maintenance. Water Quality Treatment Concerns that at least a portion of the bottoms of the ponds need to be below the seasonal high water table and that circulation of the ponds needs to be maximized in order to meet water quality treatment criteria are misplaced since there is no requirement that the pond bottoms be below the seasonal high water table in wet detention systems such as the one at issue in this case. Further, the entire bottoms of the ponds are littoral zone and meet DISTRICT rule requirements that 35 per cent of the pond be littoral zone, concentrated at the outfall. Additionally, the ponds at issue maximize circulation through the location of points of inflow and outflow. Floodplain Mitigation Concerns that volume in the floodplain mitigation area is not available because of problems with the seasonal high water table are also misplaced. Specifically, the floodplain area encroachment requiring mitigation relates to Pond 5A. There is more than enough volume within the area which will be excavated to compensate for the area where the fill will be deposited. The seasonal high water table will be at or below the floodplain mitigation area after the required excavation takes place. Although the seasonal high water table will be lowered where the excavation or cut is made and later raised where the fill is placed, no adverse effects on the water table will result from such lowering and raising of the water table. Volume In Pond 5A Allegations that the May 12 and 13 submittals reflect that Pond 5A has less volume available than the modeling calculations contemplate are incorrect. The changes in the contour lines of Pond 5A on the May 12 and 13 submittals from what was shown on the April 1 submittal occurred on the outside of the pond. The volume on the inside of the pond was not reduced actually increased when the pond bottom was lowered for water quality purposes. In determining how much volume a pond is to have when it is constructed, the computer modeling figures take precedence over the scaled plan drawings. In this case, the computer modeling figures never changed after the April 1 submittal. HORNE submitted a computer model that calculated the volume of Pond 5A. The output data clearly reflects that the top of the bank was 82 feet. Publix's Status as an Existing Site Assertions that the Publix site should have been considered in its pre-developed state since there will be approximately one acre foot of volume of runoff, or possibly less, leaving the site without retention are without validity. The Publix plaza was permitted by the DISTRICT in 1985 and constructed in 1986. The amount of peak flow discharge and overall discharge is currently authorized by a valid MSSW permit. When the DISTRICT reviews a permit application, all existing permitted surface water management systems must be accepted in their present state. There is no authority in the DISTRICT's rules to consider an existing permitted site in its pre Even if the Publix site is considered in its pre project has only .02 of an acre foot more volume of runoff in its post-developed condition than in the pre Storage of 100-Year Volume Allegations that the amount of 100-year volume being retained on site in the ponds has been incorrectly calculated by the DISTRICT and HORNE are also invalid. The DISTRICT's rules require that the difference between the pre- and post-development volume for the 100-year storm be retained on site. In the ponds which are the subject of this proceeding, the 100-year volume is retained in the ponds below the orifice. This volume cannot leave the site through the orifice; it can only leave the site by percolation into the ground or evaporation into the air.
Recommendation Based on the foregoing, it is recommended that the Southwest Florida Water Management District enter a final order granting HORNE's Application for Surface Water Management Permit No. 400317.02. RECOMMENDED this 25th day of June, 1993, in Tallahassee, Florida. DON W.

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 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. DONE AND ENTERED this 24th day of June, 2002, in Tallahassee, Leon County, Florida. DON W. DAVIS Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 24th day of June, 2002.
The Issue The issue is whether the 100 foot separation of respondents/applicants sewage treatment plant from the surface water management system is adequate.
Findings Of Fact Based upon all of the evidence, the following supplemental findings of fact are determined: Background Respondents/applicant, John D. Remington and Bolton S. Drackett (applicants), are the owners of record of approximately two thirds, or around 2,700 acres, of Keewaydin Island (Key Island), which lies just south of the mainland portion of the City of Naples, Florida. In conjunction with a planned luxury development of forty-two homes on Key Island, applicants have filed an application with respondent, South Florida Water Management District (District), seeking the issuance of a permit authorizing the construction and operation of a surface water management system (system) through which stormwater runoff from the project will be directed and controlled. Petitioner, Florida Audubon Society (FAS), has initiated this proceeding to contest the issuance of a permit. In an earlier and separate proceeding (DOAH Case No. 90-2415), applicants applied for a permit from the Department of Environmental Regulation (DER) to construct a wastewater treatment plant (plant) to serve the planned development. The permit was issued on January 2, 1990, and because all appeals by FAS in Case No. 90-2415 have been concluded, that proceeding is now final. Although the wastewater treatment plant has not yet been constructed, the parties agree that it will be situated more than one hundred feet from the surface water management system. This distance (100 feet) is the minimum amount of space allowed by District rule between the plant and system. Even so, the purpose of the remand proceeding is to determine whether that amount of separation is adequate. Thus, the factual issue here is whether the treated wastewater from the plant and filter fields will enter the surface water management system and cause a violation of applicable water quality standards and other relevant District criteria. In support of their respective positions on this issue, the parties have presented the testimony of a number of experts. In resolving the conflict in their testimony, the undersigned has accepted the more credible and persuasive testimony which is embodied in the findings below. A Brief Description of the Development and System The proposed development and surface water management system were described in detail in the prior recommended order entered in this case. For purposes of this Supplemental Recommended Order, it need only be noted that Key Island now has a lodge, guest quarters and recreation facilities, all presently served by septic tanks. Access to the island is provided by motor launch from an existing shore station. Subaqueous utility crossings from the mainland provide electric power and potable water to the island. The planned development includes the construction of forty-two large luxury homes and an expansion of the lodge facilities to accommodate the needs of the new residents. The homes will be built in phases with approximately ten to be built in the first year. The entire project may take as long as seven or eight years to complete. The proposed surface water management system was designed to handle a seventy-five residential unit development. However, by virtue of a reduction in size imposed by the City of Naples, the project has been reduced to forty-two homes. Even so, the capacity of the system has not been downsized. Therefore, the system as designed will more than accommodate all proposed development on the island. The development area has been divided into seven surface water management basins based upon seven existing natural water sheds on the upland portion of the project. Each basin will have a system of inlets, culverts and swales which will direct runoff to control structures. The dry swales are approximately one foot deep and five to ten feet wide and run parallel on both sides of the cart paths that link the various portions of the project. The cart paths, which will be at an elevation of 5.5 feet above mean sea level (NGVD), will have culverts running underneath to aid in maintaining the natural flow of water and limit impounding of water. The swale bottoms are designed to be one foot below the cart path elevation, or at 4.5 feet NGVD, and will be dry, except during significant rain events, because they are designed so that the bottom of the swale is at least one foot above the average wet season water table. Both the cart paths and swale system utilize a design system that is common to residential developments. Once the water reaches a specified height, it goes over the control structure and is discharged downstream into spreader swales from which the water is dispersed into either interior, low wetland areas or into two artificial lakes (7.3 and 1.0 acres in size) created for wet detention. Basins one, two, three, four and seven are designed to treat water quality by the dry detention method, that is, by the unlined swales that parallel cart paths, while water quality is accomplished in basins five and six by best management practices and wet retention, that is, the two artificial lakes. The Wastewater Treatment Plant The DER permit was issued on January 2, 1990, and carries an expiration date of January 2, 1995. It authorizes applicants to: construct a 0.035 MGD extended aeration process wastewater treatment plant with reclaimed water to dual absorption fields located at the project site as depicted on Wilson, Miller, Barton, Soll & Peek, Inc. design drawings, project number 6270, sheets 1 thru 5 of 5, dated March 20, 1989, revised October 16, 1989 and received October 19, 1989. The design drawings were submitted in support of construction application, engineering report, hydrologeolic characteristics and hydraulic modeling for effluent disposal report and related documents, dated March 20, 1989. The hydraulic capacity of the plant is limited to 0.030 MGD based on the reclaimed water disposal system. The collection system shall not exceed the 0.030 MGD hydraulic capacity as well. The wastewater treatment plant is designed to meet all DER water quality, health and safety standards. For example, the plant must achieve 90% removal of biological oxygen demand (BOD) and 90% removal of total suspended solids from the raw wastewater, or effluent levels below 20 parts per million for BOD and 10 parts per million suspended solids, whichever is more stringent. The plant must also have twenty-four hour detention in the aeration chamber and four hours detention in the clarifer. Further, a chlorine chamber contact time of fifteen minutes is required. In addition, DER has issued the permit with certain specific conditions. Among others, these include standards as to effluent chlorine residuals, the requirement that a professional engineer inspect the construction, operation requirements, sampling schedules, defined perameter levels, and the establishment of a hydraulic plant load (permitted maximum daily flow) at 30,000 gallons per day. By issuing the permit, DER has concluded that up to 30,000 gallons per day of sewage effluent can be treated and disposed of by the plant filter fields without violation of applicable DER water quality, health and safety standards. The wastewater treatment plant will be located on a centralized utility site within basin seven of the system. There are also gravity sand filters and a drainfield effluent disposal system located in basin six, which is the northeastern corner of the project. The plant will provide a high degree of treatment and disinfection for the effluent before it is discharged to the filter field. The filtered (treated) effluent will flow by gravity main to the filter fields located in an adjacent basin. Two filter fields will be used in disposing of the treated wastewater effluent. Constructed as sand mounds at a grade level of two or three feet above the existing island elevation, each filter will have dimensions of twenty feet wide and four hundred feet long. The filter fields will be constructed as a bed of gravel wrapped in filter cloth and placed within a mound of soil. A perforated four-inch pipe will be installed within the gravel bed at 5.5 feet NGVD to distribute the effluent through the filter beds. The effluent will then percolate downward and laterally away from the bed and into the groundwater table. At that point, the effluent will become indistinguishable from the groundwater Because the total daily flow will be pumped alternately into one part of the two sections of the drainfield, this allows one filter field to "rest" for a seven-day period during the use of the other filter field, thereby avoiding saturation. Therefore, the average theoretical maximum input into a filter field over a one year period at the plant's maximum capacity is 15,000 gallons per day. The plant was designed and permitted for maximum daily flows at all times of the year. However, the actual operating conditions will reflect significantly less flows due to the seasonality of the population and occupancy levels. More specifically, the plant was designed and permitted for seventy- five dwelling units and ancillary uses with an estimated maximum design flow of 28,450 gallons per day. The approved planned development will contain only forty-two dwelling units and ancillary uses with a maximum design flow of 21,200 gallons per day. Therefore, the permitted plant will treat the wastewater to a higher level due to the reserve capacity, and the plant will rarely be used at over fifty percent of its available capacity. Revised projected wastewater flows will range from daily loads of 2,325 gallons per day during the months of August and September to a high of 15,137 gallons per day during the month of February. This projected usage is consistent with historical occupancy and usage trends in the Naples area which show that occupancy of homes is at its peak during the dry season (the cooler winter months) and substantially lower during the wet season (the hot summer months). Applicants' projected wastewater flows are found to be reasonable and are hereby accepted. In making this finding, the undersigned has rejected the contention by FAS that the daily wastewater flows will be higher than that projected by the applicants and the plant will operate at maximum capacity for sustained periods of time. The system plans reflect that there will be swales within basin six located between one hundred ten and one hundred twenty feet to the west of the filter fields. These swales run parallel along a cart path and flow to the north discharging into an artificial lake at the north end of the project. The swales in this basin have a bottom elevation of 4.5 feet NGVD and decrease to an elevation of 3.5 feet NGVD at the point of discharge into the artificial lake. Adequacy of Separation Between Plant and System Rule 40E-4.091, Florida Administrative Code, adopts and incorporates by reference a document known as the "Basis for Review for Surface Water Management Permit Applications within the South Florida Water Management District - September 1989" (Basis for Review). Section 3.2.2.8 of the Basis for Review reads as follows: Sewage treatment percolation ponds. Above ground pond dikes shall not be within 200 feet of water bodies or 100 feet of dry detention/ detention areas. Additional calculations by the applicant may be necessary in unusual cases requiring deviations from these dimensions. The purpose of the above section is to provide adequate separation between above-ground percolation ponds and surface water management systems in case the percolation pond dike fails. For example, above grade percolation ponds contain large volumes of sewage treatment plant effluent. If a pond dike should fail, a large portion of effluent would be quickly released into the adjacent ground. The minimum 100-foot separation is designed to provide adequate distance for percolation into the ground prior to infiltrating the surface water management system. However, filter fields contain lesser volumes of effluent than do percolation ponds, and should a filter field fail, the effluent will trickle out the side of the field with a much lower rate of effluent release than from a failed pond dike. In accordance with the District rule, applicants have proposed to locate the surface water management system more than one hundred feet from the wastewater treatment plant and filtration beds. Even though the rule standards have been met, the purpose of this remand proceeding is to determine whether that amount of separation is adequate to prevent adverse impacts to the water quantity and water quality functions of the system from the operation and location of the filter fields. The Computer Models As a part of their application filed with DER in 1989, applicants' witness Missimer prepared and submitted a report known as "Hydrogeologic Characteristics and Hydraulic Modeling for Effluent Disposal at Keewaydin Club". The report was based on a computer model known as "Modflow" and was designed to show the increase in elevation of the water table for a loading rate of 30,000 gallons per day alternating between the two filtration beds. The purpose of the modeling analysis filed with DER was to investigate whether the plant would continue to discharge effluent to the drainfields under the most extreme conditions. The model demonstrated that the effluent discharge would not be impaired even under conditions that are beyond any reasonable or probable operating conditions. After reviewing the model, DER accepted those results and issued a permit. Utilizing in large part the underlying assumptions and parameters of the Missimer model, and without performing any independent field evaluation on the site, FAS witness Chin ran the model to investigate the impact of the operation of the plant on the system. Because the model used by Dr. Chin was not constructed for the design of a surface water management system, but rather was constructed for the purpose of designing an adsorption field, without modification it provided a more than worst case scenario of impacts associated with the operation of a plant. In this case, Dr. Chin utilized the ultra- conservative assumptions used in designing the adsorption field and made no revisions to the model. Thus, it is found that the model as used by Dr. Chin, and any conclusions drawn from the model alone, are not a sufficient or reasonable basis for evaluating the impact of the plant on the system. The model used by Dr. Chin is not representative of the natural occurring conditions on the island or the reasonably expected plant flow rates. Moreover, in developing the worst case scenario, as opposed to reasonable expectations, both the Chin and Missimer models incorporated the simultaneous occurrence of certain conservative assumptions including an impermeable flow boundary, a year round wet season water table elevation, a conservative rate of transmissivity, and a constant rate of evapotranspiration. The use of these assumptions caused the model output to grossly overstate the effects of the plant on the system in the following manner. First, by assuming a flow barrier on the island, the model had the effect of overestimating the height of the groundwater mound from operation of the plant than would occur if no boundary were used. Second, the assumption of a year-round wet season groundwater level is unrealistic since groundwater levels fluctuate seasonally, receding to near zero NGVD on the island during the dry season. Thus, the model overestimated the height of the groundwater level. Further, by using only the upper ten feet of the water table aquifer in calculating the rate of transmissivity, the model incorporated a much lower rate than would be attained had the entire thickness (74 feet) of the aquifer been used. This also resulted in an over-estimation in the height of the mound from the operation of the plant. Finally, by assuming a constant rate of evapotranspiration, the model "grossly exaggerated" the impact to the groundwater level from operation of the plant. In reality, as the water table increases, the loss of water from evapotranspiration increases significantly and constitutes a major output of a water budget. Besides the foregoing assumptions, the Chin model also assumed a continuous loading rate of 30,000 gallons per day for a period of up to one year. While the District should properly consider the permitted flow rate of the plant in evaluating a worst case of potential impact, there was no evidence substantiating any likelihood of the plant actually producing 30,000 gallons per day for 365 consecutive days in conjunction with all other conservative assumptions discussed above. The more reasonable and accepted method of analyzing the impact of plant flows is to examine the peak month's average day flow over a six-month period. As noted earlier, for the proposed forty-two units, the peak day flow is estimated to be approximately 21,200 gallons per day. Therefore, it is highly probable that actual flow rates will be much lower than the maximum plant capacity of 30,000 gallons per day. By failing to use the more reasonable and realistic reduced flow rates, the Chin model overestimated the elevation of the groundwater level from the operation of the plant. In contrast, the Missimer analysis demonstrates that it is extremely unlikely that the plant output will ever elevate groundwater to the extent that it would reach the system swales by either surface water or groundwater flow. The foregoing modeling assessments, including the criticisms of the Chin model, were concurred in by the District expert. Water Quantity Impacts There is no credible evidence to support a finding that the operation of the plant will adversely impact the ability of the system to provide adequate flood protection and drainage. Indeed, the more credible evidence shows that an alteration of existing drainage patterns will not occur by virtue of the operation of the plant, and the post-development discharge rates will not exceed the pre-development discharge rates. Therefore, the undersigned's previous finding that applicants have provided reasonable assurance that the the system provides adequate protection and drainage is not altered after considering the operation and location of the plant. There is insufficient credible evidence to support a finding that the plant's operation will adversely impact the system functions in such a way as to cause adverse water quantity impacts on receiving waters and adjacent lands. Indeed, the post-development discharge rate approximates the pre-development discharge rate on receiving waters, the ultimate receiving water body (the Gulf of Mexico) has an infinite capacity to receive water, and there are no adjacent lands subject to flooding from discharge of the system regardless of whether there is any impact of the plant on the system. There is no credible evidence to support a finding that the plant will cause the system to have an adverse impact on surface and groundwater levels and flows. Rather, the more persuasive evidence shows that the plant's operation will not result in groundwater elevation in the area of the system that would cause the impoundment of water or prevent the percolation of water into the soil. In addition, the overflow levels for control structures will operate as designed to insure against over-drainage or flooding. Finally, the operation of the filter fields will not cause adverse impacts on surface and groundwater levels and flows. Water Quality Impacts The operation of the plant will not impair the water quality functions of the system. This is because the swales will continue to detain the first flush of run-off allowing the majority of the suspended solids and other pollutants to settle out regardless of the operation of the plant. Further, in the unlikely event the treated wastewater effluent reached the system, it would be indistinguishable from the stormwater or rainfall due to the high level of treatment from the plant, the filter fields and dilution from groundwater and rainfall. The operation of the plant will not cause adverse water quality impacts on the receiving waters. In making this finding, the undersigned notes initially that the plant is permitted by DER, and therefore it is assumed to comply with all DER water quality standards. Second, there is no evidence that the system will impact the operation of the plant. In the event the groundwater mixed with treated effluent resurfaces, there would be no adverse impact to the surface water quality. This is because the treated effluent from the plant exceeds state water quality standards. Once the treated effluent becomes a part of the groundwater, it is unlikely that it will resurface again in the areas of the swales, which are more than one hundred ten feet away. Indeed, in order for the groundwater with effluent to travel that distance, it would have been in the groundwater system for at least one hundred days. This period of time is more than sufficient for the denitrification and adsorption processes to remove all nutrients. Even if the worst case scenario became a reality and the groundwater reached the swale bottoms, it would only result in a wetting of the ground and would not be of sufficient quantity to create a flow of water in the swale to travel off-site impacting a receiving water. In any event, at that point, any groundwater resurfacing that distance away would no longer be effluent. Finally, during abnormal conditions, such as a hurricane or large storm event, the groundwater may rise to the surface and mix with the surface water and enter the system. However, any effluent already significantly diluted under normal circumstances would be indistinguishable from the stormwater or rainfall. Adverse Environmental Impacts There is no credible evidence that the operation of the plant filter fields will adversely impact the system in such a manner as to cause an adverse environmental impact. In so finding, the undersigned rejects the contention that the system will act as a conduit for treated effluent to travel off-site to the ponds, marsh, mangrove areas or receiving waters. The evidence shows that the design of the filter fields and high permeability of the island soils will prevent the surface flow of effluent to the system swales. The elevation of the swales above the groundwater table level will prevent the introduction of effluent into the swale system. In the unlikely event the groundwater reaches the bottom elevation of the swale, there would be no significant environmental impact because the quality of effluent would be indistinguishable from the groundwater due to the high level of treatment and dilution, and such water would still be further treated by the system before discharge to receiving bodies. The location of the plant and system will not have an adverse impact on the gopher tortoise population on the island. Rather, the system should enhance the gopher tortoise population by providing mananged land with vegetation suitable for gopher consumption. Further, the general development on the island will reduce the number of raccoons which prey on gopher eggs and young gophers. Miscellaneous During the remand hearing, FAS presented evidence concerning the impact of tides and mean sea level rise and saline lakes on the island. This evidence was essentially the same as that presented in the prior hearing and was rejected in favor of the more credible evidence presented by the applicants on this issue. Nothing was presented during the remand hearing which would alter these prior findings. During the hearing, and in response to a question by District counsel, witness Missimer agreed it would not be unreasonable to install a few monitoring wells to insure that the system is operating properly. Because this requirement is not unreasonable, will serve a valuable purpose, and has been utilized by the District as a special condition on numerous prior occasions, it should be incorporated into the permit conditions. Even though the evidence clearly shows that seasonal tidal fluctuations would not have an adverse impact on the functioning of the system, if such a tidal incursion were to occur, the placement of a check valve device on the water control structures would prevent sea water from flowing back into the system. Such a device would be a minor addition to the system, would not otherwise affect its design, and if deemed necessary by the District, should be incorporated into the permit conditions. Prior to hearing, the District retained the services of an outside consultant to assist it in preparation for trial. The consultant did not testify at final hearing and prepared no reports. He did make several computer runs, none of which are a part of this record. Among other things, District witness Rogers relied upon the computer runs in formulating his opinion on the issue presented on remand.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a final order be entered granting the requested permit in accordance with the agency's proposed agency action dated March 28, 1990. DONE and ENTERED this 22 day of March, 1991, in Tallahassee, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22 day of March, 1991.
The Issue The issue is whether to approve an application by Respondent, I.M. Collier, J.V. (Collier), to modify its Environmental Resource Permit (ERP) No. 11-02031P (2002 Permit) by changing the surface water management system (SWMS) for a proposed residential and golf course development in Collier County (County), Florida, known as Mirasol.
Findings Of Fact Based on the evidence presented by the parties, the following findings of fact are made: The Parties National Audubon Society, Inc. is a not-for-profit corporation (incorporated outside the State of Florida) while Collier County Audubon Society, Inc., Florida Wildlife Federation, and Conservancy of Southwest Florida are Florida not-for-profit corporations. All are environmental organizations. Franklin Adams is a resident of the County and a member of each of the above organizations. Respondents have not contested Petitioners' standing based upon the stipulated facts set forth in the parties' Pre-Hearing Stipulation. The District is a water management district with the power and duty to exercise regulatory jurisdiction over the administration and enforcement of ERP criteria pursuant to Chapter 373, Florida Statutes, and Florida Administrative Code Title 40E. Collier is the holder of the 2002 Permit authorizing the construction of a SWMS to serve the Mirasol project, a large development located in the County. The parties have stipulated that Collier has the administrative, legal, and financial capabilities to undertake the proposed activity. Fla. Admin. Code R. 40E-4.301(1)(j). The Project Site The Mirasol project consists of approximately 1,713.45 acres located on the north side of Immokalee Road and the Cocohatchee Canal (Canal) in the northern half of the County, approximately three miles east of the intersection with Interstate 75. The property spans three sections of land, the northern third of the property encompassing Section 10, the middle third encompassing Section 15, and the southern third encompassing most of Section 22. The site also includes a peninsula of land extending east of Section 10, encompassing the northernmost quarter of Section 11. The site is bounded on the south by the Canal and Immokalee Road and on the east by an existing residential development known as Heritage Bay, which was previously a rock- mining quarry. To the west of the site, running north to south, are two other proposed residential developments known as Parklands Collier and Terafina/Saturnia Falls and an existing residential and golf course community known as Olde Cypress. There are other existing and proposed residential developments and farm fields to the north of the site. The site is located southwest of the Corkscrew Swamp Sanctuary (Corkscrew Swamp), which is owned by the National Audubon Society, Inc., and appears to stretch from Immokalee (in the northeastern part of the County) south and southwestward through parts of the County. Corkscrew Swamp sits roughly at the center of a 315-mile watershed, much of which is comprised of short hydroperiod wetlands which dry down completely during the late winter and spring and become inundated again in the late summer and fall during the wet season. This water gradually sheet flows down a very slight downhill gradient toward the south and west. A portion of the sheet flow travels southwest in the vicinity of the site. The region has experienced occasional floods, the most severe of which occurred in 1995. At the direction of the District, the cause of the flooding was investigated in the South Lee County Watershed Study (Study), which concluded that the watershed discharges through a variety of outfalls, but that historic connections to downstream conveyances like the Canal were severed by the construction. While downstream conveyances exist, the Study concluded that connections between upstream flows and downstream conveyances should be enhanced or restored. In the late 1990s, the Canal was improved to increase its conveyance capacity. A berm was constructed by the Big Cypress Basin Board (Basin Board), a legislatively-created entity which manages water resources in the County, on the northern bank in the vicinity of, and across from, the Mirasol site. This berm prevented historic wet season sheet flow from reaching the Canal through the project site, except for a few culverts located along that water body. The Basin Board also built a 1,000-foot-long hardened concrete weir on the north side of the Canal a few thousand yards west of the project site. This weir provides the primary outlet for sheet flow in and around the Mirasol site. Currently, upstream drainage flows in a southwesterly direction across Section 10. As the water moves south to the Canal, the flow becomes constricted down to a 580-foot wide gap between the Olde Cypress residential development and commercial developments along Immokalee Road to the east. This constricted area further narrows to a 270-foot wide opening before the sheet flow reaches the 1,000-foot weir and discharges into the Canal. During a 3-day, 25-year storm event, a combined peak flow of 553 cubic feet per second (cfs) of water is discharged into the Canal through the 1,000-foot weir, but the Mirasol property only conveys a small portion of this water (around 20 cfs) through culverts in the Canal berm. Most of the water flows to the west of Mirasol where it passes through the narrow gap and over the 1,000-foot weir. Around 1,431 acres of the 1,714-acre site are jurisdictional wetlands. However, these wetlands are in poor condition due to existing impediments to sheet flow, artificially high water levels during the wet season, and heavy infestation of exotic species, principally melaleuca. Permit History In February 2002, the District issued the 2002 Permit approving the construction of a SWMS to serve two 18-hole golf courses, a single-family residential community, a golf course clubhouse and parking area, golf course maintenance facilities, sales facility, and parking area. The issuance of the 2002 Permit was not challenged. The SWMS included a 36.5-acre flow-way (Flow-Way) that encircled the northern boundary of the development in Section 15 and extended off-site and across adjacent properties to the west. (If constructed, the Flow-Way would be a 200-foot wide, 4-foot deep, 89-acre channel, more than half of which would have been located on the Saturnia Falls/Terafina and Olde Cypress properties.) Besides providing a conveyance function for the Mirasol site, the Flow-Way also enhanced flood protection for other properties by accelerating conveyance of floodwaters to the Canal and reducing peak flood stages by 0.4 feet during a three-day, 25-year storm event. The District included Special Condition 26 in the 2002 Permit, which required construction of the Flow-Way before the remainder of the project could be constructed. The 2002 Permit authorized Collier to directly impact (fill or excavate) 568.66 acres of wetlands within the footprint of the development. Additionally, 39.5 acres of wetlands, which were isolated remnant strips along the golf courses within the development, were considered secondarily impacted and assessed a thirty-three percent reduction in functional value. Mitigation for the project consisted of preservation and enhancement of wetlands and uplands on site. Enhancement of the preserve areas was primarily credited to the eradication of malaleuca and other exotic species and replanting with appropriate native vegetation. Permit conditions required management of the preserve areas to prevent a recurrence of exotic species. The preserve areas included an 846.95-acre external preserve area to the north and northeast of the area to be developed. It was anticipated that this northern preserve area would ultimately be donated to an existing mitigation area known as the Corkscrew Regional Ecosystem Watershed, along with an interest-bearing fund to ensure perpetual management. In December 2005, the United States Army Corps of Engineers (Corps) denied Collier's federal wetlands permit application for the project and the Flow-Way. Because of this denial, in May 2006 Collier submitted an ERP application with the District seeking to modify the 2002 Permit by revising the SWMS and removing the Flow-Way. On October 12, 2006, the District Governing Board approved a modification to the 2002 Permit, which authorized an alternate SWMS to serve the golf course and residential development (2006 Permit). Petitioners' challenge to the proposed modification followed. The 2006 Modification Because of the Corps' denial of its application, Collier was required to remove the Flow-Way and redesign the project's SWMS. The most substantial change in the project was the removal of the Flow-Way and associated control structures and its replacement with a series of interconnected lakes running from north to south through the property allowing for the pass-through of surface waters from the area north of the development site into the Canal. The modification does not alter the boundaries and location of the development. However, the revised SWMS includes: five controlled basins with a total area of 718.43 acres, each of which provides treatment of stormwater prior to discharging into the pass-through system; 45.16 acres of interconnected lakes serving as a pass-through for surface waters from the north; 2.12 acres of perimeter berm backslope/ buffers/spreader swales; and 7.27 acres along the Canal for the existing 100-foot wide canal easement and proposed canal contouring. These changes also required elimination of the 39.5 acres of remnant wetlands inside the development that had previously been assessed as secondarily impacted. Also, there were 0.68 acres of additional impacts resulting from slight changes in the internal site design due to the SWMS. To partially offset these impacts, the internal wetland preserves were enlarged by 13.32 acres. The remaining impacts were mitigated with mitigation credits from the Panther Island Mitigation Bank (PIMB). (The PIMB holds a mitigation bank permit issued by the District for a wetland restoration project in Southwest Florida.) The main preserve was left unchanged, except that 36.5 acres previously dedicated to construction of the Flow-Way will be added to the main preserve and similarly enhanced and preserved. In summary, as modified under the 2006 Permit, the total onsite mitigation consists of the preservation and enhancement of 830.89 acres of wetlands, preservation of 109.58 acres of uplands, and the purchase of a total of 5.68 credits from the PIMB. At hearing, Collier also agreed to purchase from the PIMB an additional 5.68 credits within the Basin for a total of 11.36 credits. The ERP Permitting Criteria To obtain an ERP, an applicant must satisfy the conditions in Florida Administrative Code Rules 40E-4.301 and 40E-4.302. The first rule focuses primarily on water quantity, environmental impacts, and water quality, while the second rule generally requires that a public interest balancing test be made, that cumulative impacts, if any, be considered, and that the District consider past violations, if any, by the applicant of District or Department of Environmental Protection (DEP) rules. (The parties have cited no prior violations by the applicant that should be considered.) Besides these two rules, a number of BOR provisions which implement the rule criteria must also be taken into account. If an applicant proposes to modify an existing ERP, as it does here, Florida Administrative Code Rule 40E-4.331(2)(a) comes into play and requires that the District review the application to modify the ERP "using the same criteria as new applications for those portions of the project proposed for, or affected by, the modification." Under this rule, those portions of the project altered or affected by the modification are reviewed under the current ERP criteria, but otherwise the 2002 Permit is not the subject of review in this case. Therefore, the District's review includes only that portion of the existing permit that is proposed to be modified or affected by the modification. In this case, the 2006 design is very similar to the 2002 design, and the project's footprint, control elevations, roadway network, southern outfall, and main preserve are unchanged. However, as pointed out below, since most of the engineering-related components of the SWMS were affected by the Flow-Way's removal, the District reassessed the hydrologic components of the internal water management system and the pass- through lake system for levels of flood protection and water quality treatment. Because most of the engineering-related components of the SWMS for the project were modified as a result of the removal of the Flow-Way, the District staff reassessed the project's hydrologic calculations associated with levels of flood protection and reassessed the project's water quality treatment volumes applying the currently existing ERP criteria. As to wetland impacts and mitigation, review of the wetland impacts for the 2006 Permit was limited to an analysis of additional wetlands impacts associated with the modification. This was primarily the elimination of the previously permitted, secondarily impacted wetlands. Thus, only the additional wetlands impacts due to the revised SWMS are considered under the currently existing ERP criteria. The 2006 Permit made only slight changes to the project's wetland impacts and mitigation components authorized under the 2002 Permit. The project's footprint was not changed and the main mitigation area (the Northern Preserve) was unaffected by the changes except that 36.50 acres were actually added to that preserve as a result of the removal of the Flow- Way. Collier did not receive any credit in its mitigation analysis for the additional acreage that will become part of the preserve due to the removal of the Flow-Way. Surface Water Management Criteria As noted above, the ERP criteria in Florida Administrative Code Rule 40E-4.301 focus primarily on three areas of concern: water quantity, environmental impacts, and water quality. Related BOR provisions must also be considered. These areas of concern are discussed below. Water Quantity Florida Administrative Code Rule 40E-4.301(1)(a) requires that an applicant provide reasonable assurance that the construction of a SWMS "[w]ill not cause adverse water quantity impacts to receiving waters and adjacent lands." BOR Section 6.2 implements that provision and requires that a project be designed so that it is consistent with the downstream carrying capacity of the receiving waters. In other words, it must not exceed the capacity of downstream receiving waters, which in this case is the Canal. In making this determination, Section 6.3 of the BOR requires that the 25-year, 3-day design storm event be used. Collier complied with this requirement through an extensive hydrologic study conducted by its expert, Richard S. Tomasello, a former District employee. Applying a hydrologic model simulation known as S2DMM, the witness determined the appropriate amount of upstream sheet flow that would need to be routed through the project to avoid adverse water quantity and flooding impacts and calculated the correct dimensions of the intake weir to admit that flow into the project's pass-through system. The S2DMM model is a combination of other accepted models including the Sheet 2d, Massmod, and MBR models, which were developed by Mr. Tomasello, and they have been evaluated and used by the District on numerous occasions. In addition, the S2DMM model has been used for other flood studies in Collier and Lee Counties, and it will be used on a restoration project in Martin County. Based upon Mr. Tomasello's analysis, Collier incorporated a 100-foot-long intake weir with a crest elevation of 14.95 NGVD (National Geodetic Vertical Datum) along the northern boundary of the project to maintain existing upstream water elevations. Collier also complied with BOR Section 6.3, which requires the use of a 25-year, 3-day storm event to be used when computing the discharge rate for the project. The modified intake weir on the northern boundary includes two 3.5-foot wide rectangular notches set at an elevation of 14.00 NGVD, which will provide a "base flow" of up to 20 cfs into the pass-through lakes to mimic the current flow through the property. The determination of this base flow was made through an analysis of the existing culverts at the southern end of the property. While not required by the ERP criteria, Collier also performed a long-term analysis (using a four-year period of record) of the SWMS's effect upon water levels. This analysis demonstrated that the modified system would leave water levels in the wetland areas upstream of the project unchanged during normal rainfall and low-flow periods. This analysis provides additional assurances that the modifications to the SWMS will not affect the Northern Preserve. While Petitioners questioned the accuracy and reliability of the hydrologic study, and its specific application to this project, the criticisms are considered to be vague and unsubstantiated. As noted above, the model has been previously accepted for use in South Florida, and Petitioners' expert conceded he did not have enough information to determine the model's accuracy. The more persuasive evidence established that the hydrologic study submitted by Collier included the relevant available data and was prepared by competent professionals knowledgeable in the field. The claim of Petitioners' experts that they lacked sufficient information to form an opinion on the accuracy of the modeling is not a sufficient basis to overcome the evidence submitted by Collier to meet this criterion. The project's discharge rate in 2006 will not exceed what was permitted in the 2002 Permit. During the 25-year, 3-day storm event, the existing discharge from the project site and the natural area west of the project site into the Canal is 553 cfs. Based on modeling of the modified SWMS, the total discharge from the pass-through system will be 529 cfs, or 24 cfs less than the project's existing pre-development discharge. The discharges resulting from the project as modified in 2006 will not exceed the capacity of the Canal as required by Section 6.3 of the BOR. Accordingly, Collier has provided reasonable assurance that the discharge rate allowed for its project would not be exceeded, as required in Section 6.2 of the BOR. Section 6.8 of the BOR requires that a project allow the passage of drainage from offsite areas to downstream areas, which is necessary to demonstrate that off-site receiving water bodies are not being adversely affected. Collier complied with this provision by conducting the hydrologic analysis using the 25-year, 3-day design storm event, which demonstrated that the discharge rate would be directed to the southern discharge point allowing for the passage of drainage from offsite areas to the downstream areas. The evidence also shows that the current predominant sheetflow from areas outside the project passes through a narrowly constricted area west of the project and discharges into the Canal over an existing concrete weir. See Finding of Fact 9, supra. Only a small portion of the upstream waters currently discharge through the Mirasol site. Petitioners' allegation that the construction of the project will further constrict the sheetflow area is rejected, as the constriction of sheetflow will continue to exist whether the project is built or not. The evidence also shows that the project will not further constrict the flow because it will allow for the pass-through of water from outside the project area. Under the 2002 Permit, the Flow-Way was designed to aid in the diversion of upstream flows around the project. Under the 2006 modifications, the pass-through lake system will convey up to forty percent of the upstream flow through the development which complies with the provisions of Section 6.8 of the BOR. As indicated above, during periods of lower water levels, the notches in the weir along the northern boundary will allow for the flow to pass onto the project site consistent with existing conditions. During major storm events, water will pass over the weir into the pass-through lake system to be conveyed to the Canal. Therefore, Collier has provided reasonable assurance that the criteria in Section 6.8 have been met. Section 6.10 of the BOR requires that the project be designed to conserve water and site environmental values and not lower the water table or groundwater or over-drain wetlands. Section 6.11 of the BOR provides that the control and detention elevations for the project must be established at elevations to accomplish the objectives of Section 6.10. The latter section is adhered to when the control elevations proposed for a project are established consistent with the onsite wetland conditions. In this case, the control elevations for the wetlands and surface water management lakes are essentially the same as the design in the 2002 Permit. Collier has set the control elevations above the average wet season water table (WSWT) for the area, thereby ensuring that the SWMS will not over-drain and will conserve fresh water. Section 6.11 of the BOR addresses Detention and Control Elevations which are intended to assist in complying with the provisions of Section 6.10. The SWMS design control elevation maintains the detention component and the control (wetland protection) elevations in the previously approved SWMS. The control elevations were set by the design engineers in consultation with Collier's wetland ecologist taking into account the ground elevations and biological indicators. The control elevation for the pass-through system and internal drainage basins work in conjunction with the control elevation along the northern boundary of the project and the control elevation for the discharge point along the southern boundary to ensure that the project does not overdrain the wetlands and to preserve the project site's environmental values. By setting the control elevation above the WSWT, the design ensures that the wetlands will not be drawn down below the average WSWT and the SWMS will not over-drain them. Section 6.10 also requires that a project not lower water tables so that the existing rights of others would be adversely affected. Again, based on the control elevations, the water table is not expected to be lowered so there should be no effect on the existing rights of others. Collier must further demonstrate that the site's groundwater recharge characteristics will be preserved through the design of the SWMS. Collier complied with this requirement by setting the control elevations above the average WSWT, allowing standing water in the wetland preserves to recharge the groundwater. The ability of the SWMS to accept flows from the Northern Preserve conserves freshwater by preventing that water from being discharged downstream. The SWMS leaves water elevations in the Northern Preserve unchanged. Consequently, water will remain in the wetlands for the same duration and elevations as in the existing conditions, thereby preserving groundwater recharge characteristics. Section 6.12 of the BOR prohibits lake designs that create an adverse gradient between the control elevations of the lakes and the adjacent wetlands. To satisfy this requirement, Collier set all control elevations at 13.4 - 13.5 NGVD while controlling the internal wetland preserves at a slightly higher elevation. Consequently, there is no adverse gradient and no potential for an adverse effect upon the internal preserves from adjacent lakes. Petitioners argued that the pass-through system would quickly lower water levels in the internal wetland preserves. However, the internal wetlands are still protected from drawdown because there are control structures set at or above the wet season elevation between the pass-through lakes and internal wetlands. They also argued that the internal wetlands would be overdrained during the dry season by the deep lakes. However, no witness presented any real analysis to back up this contention. Indeed, the pass-through lakes are only twelve feet deep, and the wetlands are separated from all the lakes by protective berms to avoid any drawdown. In summary, Collier has provided reasonable assurances that the proposed modification in the 2006 Permit will not cause adverse water quantity impacts to receiving waters or adjacent lands and will not exceed the capacity of the downstream receiving waters (the Canal). Flooding Florida Administrative Code Rule 40E-4.301(1)(b) requires Collier to demonstrate that the project "[w]ill not cause adverse flooding to on-site or off-site property." BOR Section 6.4 sets forth criteria and standards for implementing this requirement and provides that building floors be designed to be protected from a 100-year, 3-day storm event. BOR Section 6.5 provides criteria and standards for flood protection for the project's roads and parking lots. Collier complied with these provisions by providing construction plans demonstrating that the building floors and roads will be built higher than the 100-year, 3-day storm event. BOR Section 6.6 provides that a project may not result in any net encroachment into the 100-year floodplain. Collier was also required to comply with the historic basin provision in Section 6.7 of the BOR, which requires the project to replace or otherwise mitigate the loss of historic basin storage provided by the site. The level of encroachment into the 100-year flood plain and loss of historic basin storage attributed to the project are essentially unchanged from the 2002 design. The only difference between the 2002 Permit and the 2006 Permit is how the conveyance of flood water is provided. In 2002, the Flow-Way served this function, while the pass-through system provides it in the 2006 Permit. Collier's flood simulations demonstrated that the project will not alter flood stages during the 25-year and 100- year design storms, while the testimony of witnesses Tomasello and Waterhouse established that the project will not have adverse flooding impacts on adjacent properties, either alone or in conjunction with neighboring developments. Storage and Conveyance Florida Administrative Code Rule 40E-4.301(1)(c) requires that an applicant demonstrate that the proposed development "[w]ill not cause adverse impacts to existing surface water storage and conveyance capabilities." This criterion is closely related to paragraph (1)(b) of the same rule, which prohibits adverse flooding to onsite or offsite property. Section 6.6 of the BOR implements this provision and specifies the parameters for applying this criterion and prohibits a net encroachment between the WSWT and the 100-year event which will adversely affect the existing rights of others. Collier addressed this criterion through the hydrologic analysis submitted. As previously found, that model is the appropriate model to determine flood stages and to calculate the floodplain. Engineering Design Principles Florida Administrative Code Rule 40E-4.301(1)(i) requires an applicant to provide reasonable assurances that the SWMS "[w]ill be capable, based on generally accepted engineering and scientific principles, of being performed and of functioning as proposed." Section 7.0 of the BOR contains the specific standards and criteria to implement this rule. The evidence demonstrates that the SWMS is based on generally accepted engineering and scientific principles and is capable of performing and functioning as proposed. Section 8.0 of the BOR includes various assumptions and information regarding the design of the SWMS. By incorporating these assumptions into the design, Collier complied with Section 8.0. Water Quality Impacts Florida Administrative Code Rule 40E-4.301(1)(e) requires that the proposed modification "[w]ill not adversely affect the quality of the receiving waters such that the water quality standards set forth in Chapters 62-4, 62-302, 62-520, 62-522 and 62-550, F.A.C., including any antidegradation provisions of paragraphs 62-4.242(1)(a) and (b), subsections 62- 4.242(2) and (3), and Rule 62-302.300, F.A.C., and any special standards for Outstanding Florida Waters and Outstanding National Resource Waters set forth in subsections 62-4.242(2) and (3), F.A.C., will be violated." Stated more plainly, the proposed modifications must not adversely affect the quality of the Canal's waters such that State water quality standards will be violated. Section 5.2 of the BOR describes the District's standard water quality criteria. This provision, which requires a minimum of one-inch detention of stormwater, is referred to as a "presumptive criteria" because it is presumed that if an applicant provides the required one inch of detention, it meets Class III water quality standards, thereby satisfying the rule. As it did under the 2002 Permit, Collier satisfies the presumptive criteria with the 2006 design by providing the one- inch wet detention in its lake system. In fact, the system is designed to provide one and a half inches of treatment in the lake system thereby providing additional treatment. The receiving body of water for the project is the Canal. When the 2002 Permit was issued, the Canal was classified as a Class III water body. It is now classified by DEP as impaired for iron and dissolved oxygen. Because of this new classification, Collier must now comply with Section 4.2.4.5 of the BOR, which reads as follows: If the site of the proposed activity currently does not meet water quality standards, the applicant must demonstrate compliance with the water quality standards by meeting the provisions in 4.2.4.1, 4.2.4.2, and 4.2.4.3, as applicable, and for the parameters which do not meet water quality standards, the applicant must demonstrate that the proposed activity will not contribute to the existing violation. If the proposed activity will contribute to the existing violation, mitigation may be proposed as described in subsection 4.3.1.4. Collier demonstrated that neither short-term (during construction) nor long-term (during operation) water quality impacts will occur. It complied with the short-term requirements by submitting a Construction Pollution Prevention Plan detailing how water quality will be protected during the construction process. As to long-term impacts, the Terrie Bates Water Quality Memorandum (Bates Memo) prepared by District staff on June 11, 2004, provides guidance on the implementation of Section 4.2.4.5 for projects which discharge into an impaired water body. The document sets forth a number of design and operational criteria for the types of additional measures that can be incorporated into a project design to provide the necessary reasonable assurance. The Bates Memo suggests that an additional fifty percent of treatment be incorporated into a SWMS. Collier complied with this suggestion by designing the treatment lakes to provide an additional one-half inch of treatment for the additional fifty percent treatment. In addition to the one and one-half inch treatment, Collier is implementing six of the seven items the Bates Memo lists as potential options to consider. The long-term water quality requirement is addressed by Collier, in part, through an Urban Stormwater Management Plan, which details various source controls or best management practices to be implemented once the project is built and operating. Best management practices assist in ensuring that pollutants will not enter into the lake system. Collier is also implementing a stormwater pollution prevention plan and will utilize the lake system for additional treatment downstream. Collier has further agreed to planting the littoral zones as part of its design of the treatment lakes to provide additional pollutant removal. The design calls for an amount of littoral zones equal to twenty percent of the surface area of the treatment lakes. Collier has agreed to make a Water Quality Monitoring Plan a permit condition, even though such a condition was not included in the staff report. See Collier Exhibit 25. The Bates Memo includes as an option for meeting the long-term requirement a site-specific water quality evaluation of pre vs. post-development pollutant loadings. Collier has presented several such analyses, all of which indicate the post- development pollutant discharges from the site will be less than the pre-development. Mr. Barber prepared a pre vs. post- analysis using a 2003 methodology developed by Dr. Harper. The 2003 version of the Harper methodology is currently accepted by the Corps. (Although Petitioners' witness, a former Corps employee, suggested that the Corps' acceptance of the study was a "political" rather than a scientific decision, there is insufficient evidence to support this contention.) Besides his first analysis, at the direction of the District staff, Mr. Barber prepared a second analysis using the 2003 methodology with certain conservative assumptions that limited the pollutant residents time to fifty days and utilized lower starting concentrations for phosphorous and nitrogen than were recorded in the nearby monitoring stations. Based upon those reports, the District's staff concluded that Collier had provided reasonable assurances that the project met the criteria in BOR Sections 5.2 and 4.2.4.5. At the hearing, Mr. Barber presented a third analysis utilizing an updated methodology developed by Dr. Harper in February 2006. The 2006 methodology was developed after Dr. Harper conducted a study of water management district criteria throughout the state for DEP. All three of the analyses prepared by Mr. Barber concluded that the project would discharge less nitrogen and phosphorous into the receiving body in the post-development condition than is currently being discharged in the pre-development condition. In addition to the three water quality submittals from Mr. Barber, Collier provided an additional water quality analysis specific to the project prepared by Dr. Harper. See Collier Exhibit 26, which is commonly referred to as the Harper Report. The analysis evaluated the project's pre vs. post- development water quality loads and also concluded the project would not contribute to the impairment of the Canal. In preparing his analysis, Dr. Harper relied solely on the lakes for estimating removal of pollutants without accounting for any of the additional treatment expected to occur from the source control best management practices contained in the Urban Stormwater Management Plan, which means his report errs on the conservative side. The Harper Report concluded that iron discharges from the SWMS would be extremely low and substantially less than the Class III standard of 1 mg/L. Petitioners presented no specific evidence to counter these conclusions. Petitioners questioned the Harper Report's use of wetlands as part of the loading calculations and attacked his underlying methodology. However, the evidence is clear that wetlands contribute to the water quality constituents in the pre-development condition. This finding is based on data from monitoring stations located in the middle of Corkscrew Swamp, a statewide study on stormwater treatment and wetlands, and the United States Environmental Protection Agency's (EPA) assignment of nutrient loading rates to wetlands in its regional pollutant loading model. Ignoring the actual water quality in pre-development conditions would not be a true pre vs. post-development analysis. Finally, Petitioners' contention that the Harper methodology should not be considered as admissible evidence because it constitutes "novel" (and therefore unreliable) scientific evidence under the rationale of Frye v. United States, 293 F. 1013 (D.C. Cir. 1923), has been rejected. To begin with, the Frye test has not been accepted in Florida administrative proceedings. Moreover, the methodology is the basis for a new statewide rulemaking effort, has been accepted by the EPA, the Corps, and by the Division of Administrative Hearings in at least two proceedings, and has been subjected to two peer reviews. Petitioners also alleged that Collier failed to show that it complied with Florida Administrative Code Rule 62- 40.432(2)(a)1., a rule administered by DEP which requires that a new SWMS "[a]chieve at least 80 percent reduction of the average annual load of pollutants that would cause or contribute to violations of state water quality standards." However, this is a broad overstatement of DEP's rule. Also, there is no eighty percent removal efficiency requirement adopted or incorporated into any District rule or BOR criteria. See, e.g., Conservancy of Southwest Florida, Inc. v. G.L. Homes of Naples Associates II, LTD et al., DOAH Case No. 06-4922 (DOAH May 15, 2007, SFWMD July 11, 2007). Instead, the District's "presumptive criteria" is that one inch of volumetric treatment required in Section 5.2 of the BOR meets the Class III standards. If, as in this case, additional assurances are required, those assurances are met through implementation of the BOR Section 4.2.4.5. Finally, Florida Administrative Code Rule 62-40.110(2) provides that Rule Chapter 62-40 is "intended to provide water resource implementation goals, objectives, and guidance for the development and review of programs, rules, and plans relating to water resources." Also, Florida Administrative Code Rule 62- 40.110(4) states that "[t]his chapter, in and of itself, shall not constitute standards or criteria for decisions on individual permits. This chapter also does not constitute legislative authority to the Districts for the adoption of rules if such rules are not otherwise authorized by statute." Even if an eighty percent reduction standard applied, Collier has demonstrated that the project very likely will remove eighty percent or more of pollutants when additional low-impact development techniques, pollutant source reduction practices, and additional uncredited wet and dry detention capacity are considered. Based upon the evidence presented, Section 4.2.8 of the BOR regarding cumulative impacts for water quality is not applicable in this case. Collier's submittals provide reasonable assurances that the project will not be contributing to the water quality impairment of the Canal or contribute to any other water quality violation. Indeed, the information submitted indicates there will be an incremental improvement in the post-development condition as compared to existing. Since no contribution or impacts to water quality are expected, a cumulative impact analysis is not necessary to assess the extent of the impacts. The combination of all these water quality measures, when taken together, demonstrates that the 2006 Permit will not adversely affect the quality of receiving waters such that state water quality standards will be violated. Therefore, reasonable assurance has been given that Florida Administrative Code Rule 40E-4.301(1)(e) will be satisfied. Wetland Impacts Florida Administrative Code Rule 40E-4.301(1)(d) requires Collier to provide reasonable assurance that the modification of the SWMS "[w]ill not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters." In determining whether this criterion has been satisfied, it is also necessary to determine whether any 2002 permitted impacts should be subject to a second review in this case. Mitigation is a method by which an applicant can propose to impact certain wetlands on the project site in exchange for providing compensation in the form of preserving, enhancing, restoring, or creating wetlands or uplands to offset those impacts. As noted earlier, there has been no change to the wetland impacts or mitigation proposal as it relates to the Northern Preserve. See Findings of Fact 27 and 28, supra. As a result of the modified SWMS, there has been some additional impact to wetlands within the development area of the project. An additional 40.18 acres will be impacted under the 2006 Permit mostly due to the modified SWMS system. However, 39.5 acres of those wetlands were already considered secondarily impacted under the 2002 Permit. In addition, the preserve areas were expanded by 13.32 acres in the 2006 design. Thus, a portion of the impacts to those wetlands was already factored into the mitigation plan that was developed and approved for the 2002 Permit. As a result, there are 26 acres for which mitigation is necessary under the 2006 Permit. Section 4.3 of the BOR specifies criteria for mitigation proposed as part of an ERP application. Collier has proposed an acceptable mitigation plan for the new wetland impacts that will result from the project due to the proposed modifications incorporated in the 2006 Permit. Except for the mitigation for the additional wetland impacts, the mitigation plan for the 2006 Permit remains essentially unchanged from the 2002 Permit, including the Grading and Planting Plan, Monitoring Plan, and Mitigation, Monitoring, and Maintenance Plan. The onsite mitigation proposal includes preservation and restoration of wetlands through the removal of melaleuca and other exotic plants and replanting in areas of dense exotic species coverage. Significantly, Collier has not proposed any modifications that would change the effectiveness of the Northern Preserve in providing mitigation for the wetland impacts proposed and approved in the 2002 Permit. While Petitioners claim that the wetlands in the Northern Preserve may be subject to some changes in the level and seasonality of inundation as a result of the SWMS modifications, the evidence does not support those assertions. The revised SWMS will continue to allow water to flow through the Northern Preserve in a manner consistent with existing conditions while providing some flood control protection for extreme rainfall events. Petitioners also suggest that additional analysis regarding the timing and levels of inundation in the wetland preserves is necessary to fully determine the impacts of the modified SWMS on the wetlands. However, the more persuasive testimony indicates that the timing and levels within the wetlands will not be affected by the revised SWMS. The control elevations within the development area have not changed from the 2002 Permit, and these protect the onsite wetlands and ensure that those wetlands will function as expected. With respect to the internal wetlands within the development area, the control elevations have not changed from the 2002 Permit and the evidence establishes that the internal wetlands will continue to function and operate as contemplated in the 2002 Permit. There has been some relocation and reconfiguration of the internal wetland preserve areas that will actually enhance the value of the mitigation by connecting those wetland areas to other preserve areas. Petitioners further suggested that the wetland mitigation within the development area would not function as permitted in the 2002 Permit due to the spill over from the lakes to the wetlands. However, when the water reaches those internal wetland preserves, it has been treated to Class III water quality standards. Therefore, the mitigation values of those wetlands preserves will not be changed or affected due to water quality. Petitioners' objections to the wetland impacts and mitigation were primarily directed at the overall impacts rather than to the 2006 modifications. However, their witness was unaware of the values provided by the additional acres that will be impacted through the 2006 Permit. Therefore, a challenge to 2002 permitted wetlands impacts and mitigation is inappropriate in this proceeding. Functions To Fish and Wildlife and Listed Species Section 4.2.2 of the BOR implements Florida Administrative Code Rule 40E-4.301(1)(d) and provides that an applicant must provide reasonable assurances that a project will not cause adverse impact to the abundance and diversity of fish, wildlife, and listed species or their habitat. With respect to the 586.66 acres of wetland impacts permitted in the 2002 Permit, the 2006 Permit does not modify or affect the values that the wetlands provide to either the abundance or diversity of fish and wildlife. Review of the wetlands criteria as to those acres was finally determined in the 2002 Permit and should not be reopened. By relocating thirteen of the previously impacted acres so they are most closely connected to other wetlands, their value to fish and wildlife will increase. As explained by the District's witness Bain, if Collier had moved the preserve area and changed its functional value, the District would have been required to reevaluate the mitigation that had been accepted for the wetland impacts in the 2002 permit. In this case, however, because the Northern Preserve area did not change, the District's review is limited to the newly impacted wetlands internal to the development for which mitigation was not provided in the 2002 Permit. Section 4.2.2.3 of the BOR addresses the functional assessment of the values provided by the project's wetlands. The only wetland values assessed in the 2006 Permit were the additional wetland impacts that were not mitigated in the 2002 Permit. The evidence establishes that the current value of the wetlands is low due to the heavy melaleuca infestation, which is greater than fifty percent coverage in most locations and seventy-five percent or more in much of the area. Melaleuca has the effect of draining short hydroperiod wetlands. While Petitioners may disagree with how the wetlands were previously evaluated, nothing in the 2006 modification allows or requires a reassessment of their value. Section 4.2.2.4 of the BOR requires that a regulated activity not adversely impact the hydroperiod (the depth, duration, or frequency of inundation) of wetlands or other surface waters. Subsection (a) of this standard applies if the project is expected to reduce the hydroperiod in any of the project's wetlands. Conversely, subsection (b) applies if the project is expected to increase the hydroperiod through changing the rate or method of discharge of water to wetlands or other surface waters. Subsection (c) requires monitoring of the wetlands to determine the effects of the hydrological changes. Again, there is no basis for the District to reopen and reevaluate the wetlands for which mitigation has already been permitted. No evidence was presented to indicate that there would be any obstacles or problems to accomplishing the mitigation that was proposed and accepted in 2002. In any event, the engineering and biological testimony demonstrated that no change (neither a reduction nor an increase) in the hydrology on the preserved wetlands or the Northern Preserve will occur from what was permitted in the 2002 Permit. By analyzing the various biological indicators onsite and setting the control elevations within the SWMS and the wetlands (both the Northern Preserve and onsite preserve wetlands) above the WSWT, the project ensures that the appropriate hydrology will be maintained. Though the fish and wildlife are not expected to be adversely affected by the 2006 Permit, Collier will be conducting monitoring of plants and animals on the site as an extra measure of assurance as contemplated under BOR Section 4.2.3.4(c). Focusing on just the changes from 2002 to 2006, Petitioners' two experts conceded that the hydrology in the Northern Preserve and its value to wildlife and listed species (including the wood stork) would be benefited in the 2006 Permit over that contemplated in the 2002 Permit due to the removal of the Flow-Way. Secondary Impacts to Water Resources Florida Administrative Code Rule 40E-4.301(1)(f) requires a demonstration that the proposed activities "[w]ill not cause adverse secondary impacts to the water resources." A similar demonstration is required by Sections 4.1.1(f) and 4.2.7 of the BOR. In this case, the secondary impacts considered by the District were potential impacts due to the relocation and expansion of the buffer preserve areas to the perimeter of the project site. In conducting a secondary impact analysis, BOR Section 4.2.7 requires that the District consider only those future projects or activities which would not occur "but for" the proposed system. Here, the evidence demonstrated that no wetlands or other surface waters will be secondarily impacted by the modifications to the SWMS as part of the 2006 Permit. The undersigned has rejected Petitioners' contention that a proposed extension of County Road 951 through the development site should be considered a secondary impact in evaluating this project. This extension has been proposed for at least fifteen years and its precise configuration is unclear. It is not required to be built as a result of the project and there are no firm plans or contracts in place to construct the road. Although the road is listed on the County's transportation plan, it remains speculative as to if and when it will be built. Additionally, there is no evidence the County has any ownership interest in property for a road in the area identified by Petitioners. Witness Bain testified that the District examined the Collier County Public Records and an easement had not been granted to the County to build the road. i. Elimination and Reduction Florida Administrative Code Rule 40E-4.301((3) provides in part that "the provisions for elimination or reduction of impacts contained in the [BOR] shall determine whether the reasonable assurances required by subsection 40E- 4.301(1) and Rule 40E-4.302, F.A.C., have been provided." Section 4.2.1.1 of the BOR implements that provision and provides that elimination and reduction of impacts is not required when: The ecological value of the function provided by the area of wetland or other surface water to be adversely affected is low based on site specific analysis using the factors in subsection 4.2.2.3 and the proposed mitigation will provide greater long term ecological value than the area of wetland or other surface water to be adversely affected; . . . In accordance with that section, Collier was not required to implement practicable design modifications to reduce or eliminate impacts. The District did a site-specific analysis of the quality of the 39.5 acres of adversely affected wetlands, taking into consideration the condition of the wetlands, hydrologic connection, uniqueness, location, and fish and wildlife utilization. The unrebutted testimony is that the quality of the 39.5 acres of wetlands to be impacted by the 2006 Permit is low and these wetlands were already previously authorized to be secondarily impacted. The low quality wetlands are melaleuca dominated making them not unique. The mitigation will provide greater long-term ecological value than the impacted wetlands. As noted on page 10 of the Staff Report, there will be a larger, contiguous mitigation area to offset direct impacts to previously preserved, but secondarily impacted wetlands and the preservation/enhancement of the external preserve area. The 2006 Permit provides that 5.68 credits are required to be purchased in the PIMB. Collier has advised the District that 27.68 credits are being purchased pursuant to its Corps permit. Thus, Collier will be purchasing more credits than required by the District. Witness Bain took this additional mitigation into account in determining whether the proposed mitigation will provide greater long term ecological value than the area impacted. While the Corps permit is an entirely separate permit action, Collier has agreed to include an additional 5.68 credits within the Basin beyond what is required in the Staff Report as a condition to this 2006 Permit. Therefore, the mitigation is clearly of greater long-term ecological value than the area impacted. Additional Requirements Florida Administrative Code Rule 40E-4.302 imposes additional requirements on an ERP applicant, including a cumulative impact assessment, if appropriate, and satisfaction of a public interest test. Cumulative Impacts Florida Administrative Code Rule 40E-4.302(1)(b) requires that an applicant demonstrate the project "[w]ill not cause unacceptable cumulative impacts upon wetlands and other surface waters as set forth in subsections 4.2.8 through 4.2.8.2 of the [BOR]." Cumulative impacts are the summation of unmitigated wetland impacts within a drainage basin, and a cumulative impact analysis is geographically based upon the drainage basins described in Figure 4.2.8-1 of the BOR. See Florida Wildlife Federation et al. v. South Florida Water Management District et al., 2006 Fla. ENV LEXIS 49 at *49, DOAH Case Nos. 04-3064 and 04-3084 (DOAH Dec. 3, 2006, SFWMD Dec. 8, 2006). Also, Section 373.414(8)(a), Florida Statutes, requires the District to consider the cumulative impacts upon surface water and wetlands within the same drainage basin. Thus, the cumulative impact analysis applies only when mitigation is proposed outside of the drainage basin within which the impacts are to occur. Broward County v. Weiss et al., 2002 Fla. ENV LEXIS 298 at *29, DOAH Case No. 01-3373 (DOAH Aug. 27, 2002, SFWMD Nov. 14, 2002). In this case, all of the proposed mitigation associated with the 2006 Permit modifications is located within the West Collier Basin. The evidence shows that the mitigation will offset the impacts to wetlands proposed in the 2006 Permit. Therefore, since the mitigation will be performed in the same Basin as the impacts and will offset the adverse impacts, the District must "consider the regulated activity to meet the cumulative impact requirements" of Section 373.414(8)(a), Florida Statutes. A new cumulative impacts analysis based on removal of the Flow-Way is not necessary because the modification does not change the cumulative impacts analysis conducted in the 2002 Permit. Since the Flow-Way was not considered a wetland impact or contributing to the mitigation in the 2002 Permit, its removal does not affect the adequacy of the previously conducted cumulative impacts analysis or the mitigation. Accordingly, there is no need for a new cumulative impact analysis with regards to the Northern Preserve. Finally, contrary to Petitioners' assertion, there is no rule or BOR provision which requires Collier to mitigate for the alleged prior impacts of other projects. Public Interest Test In addition to complying with the above criteria, because the project is located in, on, or over wetlands or other surface waters, Collier must also address the criteria contained in the Public Interest Test in Florida Administrative Code Rule 40E-4.302(1) and Section 4.2.3 of the BOR by demonstrating that the project is not contrary to the public interest. See also § 373.414(1)(a), Fla. Stat. Since the project does not discharge into an OFW or significantly degrade an OFW, the higher standard of "clearly in the public interest" does not apply. In determining compliance with the test, Florida Administrative Code Rule 40E-4.302(1)(a) requires that the District do so by "balancing the [seven] criteria [in the rule]." Findings with respect to each of the seven criteria are set out below. (Except for pointing out that the District does not have an adopted rule which provides more specific detail on how to perform the balancing test than is now found in paragraph (1)(a), and a contention that witness Bain's testimony was insufficient to explain how the staff balanced those factors, Petitioners did not present any evidence at hearing or argument in their Proposed Recommended Order in support of their contention that the above rule, BOR section, or the associated statute have been applied by the District in an unconstitutional manner.) Whether the regulated activity will adversely affect the public health, safety, or welfare or the property of others (40E-4.302(1)(a)1.) Collier provided reasonable assurances that the project will not cause any onsite or offsite flooding nor cause any adverse impacts to adjacent lands because the SWMS is designed in accordance with District criteria. Also, the post- development peak rate of discharge does not exceed the allowable discharge rate. Further, the project will not cause any environmental hazards affecting public health, safety, or welfare. The project is considered neutral as to this factor. Whether the regulated activity will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats (40E-4.302(1)(a)2.) For the direct wetland impacts under the 2006 Permit, Collier proposes mitigation which has not changed from the 2002 Permit. The mitigation proposed was previously determined to offset potential impacts to fish and wildlife and particularly wood stork habitats. The evidence indicates that the mitigation plan for the Northern Preserve will improve wood stork habitat from its current melaleuca infested condition. For the additional 40.18 acres of wetland impacts authorized in 2006, the mitigation is of greater long-term value. Thus, the project should be considered positive as to this factor. Whether the regulated activity will adversely affect navigation or the flow of water or cause harmful erosion or shoaling (40E-4.302(1)(a)3.) The parties have stipulated that the project will not adversely affect navigation. In addition, no evidence was introduced to suggest that the project's construction would result in harmful erosion or shoaling. Whether the regulated activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity (40E-4.302(1)(a)4.) The project does not provide any fishing, recreational values, or marine productivity. Therefore, the project is neutral as to this factor. Whether the regulated activity will be of a temporary or permanent nature (40E-4.302(1)(a)5.) It is undisputed that the project is permanent in nature. Even though the project is permanent, it is considered neutral as to this factor because mitigation will offset the permanent wetland impacts. Whether the regulated activity will adversely affect or will enhance significant historical and archaeological resources under the provisions of Section 267.061, F.S. (40E- 4.302(1)(a)6.) The parties have stipulated that no significant archeological or historical resources have been identified on this site. Therefore, the project is considered neutral as to this factor. The current condition and relative value of functions being performed by areas affected by the proposed regulated activity (40E-4.302(1)(a)7.) The current condition and relative value of functions being performed by the areas affected by the project is low due to the melaleuca infestation. Project mitigation will restore 940 acres of poor quality wetlands and uplands, greatly enhancing their function and value. Therefore, the project should be considered positive as to this factor because the implementation of the mitigation offsets the wetland impacts and improves the current value. Summary of Public Interest Factors Overall, the project is no worse than neutral measured against any one of the criteria individually. Therefore, the project is not contrary to the public interest.

The Issue Petitioners challenge the South Florida Water Management District’s (the District) proposed action to issue Individual Environmental Resource Permit (ERP) 50-06558-P to authorize conceptual approval of a surface water management (SWM) system to serve 1,919 acres of a phased, multiple-use development referred to as the Palm Beach County Biotechnolgy Research Park (BRP) and to authorize construction and operation of Phase 1A of that proposed project. The ultimate issue is whether the Applicants provided reasonable assurances that the proposed activities will not be harmful to the water resources of the District; will not be inconsistent with the overall objectives of the District; and will comply with the water quantity, environmental, and water quality criteria of the District’s ERP regulations, which are set forth in Part IV of Chapter 373, Florida Statutes, Florida Administrative Code Chapter 40E-4, et. seq.; and the Basis of Review for Environmental Resource Permit Applications Within the South Florida Water Management District – September 2003 (BOR).1
Findings Of Fact THE PARTIES The Florida Wildlife Federation, Audubon Society of the Everglades, and Jupiter Farms Environmental Council, Inc. (d/b/a Loxahatchee River Coalition) are not-for-profit corporations in existence prior to 2003 with more than 25 members in Palm Beach County. Palm Beach County Environmental Coalition was formed in 1997 and is a private, county-wide, non-profit citizen’s organization. Ms. Ketter, Mr. Bell, Ms. Larson, and Mr. Christensen are individuals affected by the proposed BRP. The Respondents stipulated that the parties who remained Petitioners after Mr. Silver’s withdrawal as a Petitioner have standing to bring this proceeding. The District, a public corporation existing by virtue of Chapter 25270, Laws of Florida, 1949, operates pursuant to Chapter 373, Florida Statutes, and Title 40E, Florida Administrative Code, as a multipurpose water management district with its principal office in West Palm Beach, Florida. The County is a duly-constituted governmental entity. THE PROJECT SITE AND ADJACENT LANDS The site of the project is generally referred to as the Mecca Farms, which is a contiguous tract of 1,919 acres of land. At present, the Mecca Farms is used for farming and mining operations. There presently exists a permitted, SWM system on the Mecca Farms that was first permitted in 1979, and has been modified from time to time since then. The existing SWM system includes 73 acres of ditches and a 272-acre above-ground impoundment area. The Mecca Farms site is located within the C-18 Basin. There are no jurisdictional wetlands or delineated surface waters on the Mecca Farms. The following, which is taken from the Staff Report (SFWMD Ex. 1), accurately describes the project site and its adjacent lands: The project site consists of 1,919 acres presently supporting an active orange grove with approximately 73 acres of associated drainage and irrigation ditches/canals and a 30-acre active sand mining operation. The ditches/canals are presently maintained at an elevation of approximately 17 feet NGVD.[3] These ditches/canals provide drainage conveyance to a 272-acre above- ground impoundment located in the northeast corner of the site utilizing four (4) 22,000 gpm pumps. The above-ground impoundment discharges to the west leg of the C-18 Canal via gravity discharge. Project site ditches and canals also connect directly to the C-18 Canal through an 18,000 gpm pump. An additional 224-acre agricultural area east of the 1,919 acres of orange groves is connected to and drains into the canal/ditch system on the project site. This adjacent area was leased from the adjacent land owner by the grove owner for use as row crops and was connected to the grove canal/ditch system for better control of drainage and irrigation. The area is no longer used for row crops. There is also a small area on the site that contains caretaker housing and an equipment maintenance building for the orange groves. These facilities were originally permitted in 1979 under Surface Water Management Permit No. 50-00689-S and subsequent modifications. The citrus grove and primary drainage facilities have been in existence since the 1960s. The Hungryland Slough is located north of the project site, separated from the project site by the C-18 Canal. This area is comprised primarily of publicly-owned natural areas, including an area referred to as Unit 11, which is owned in the majority by Palm Beach County. To the west is the J.W. Corbett Wildlife Management Area (CWMA) owned and managed by the Florida Fish and Wildlife Conservation Commission (FFWCC). To the east, a large area of low-intensity agricultural land exists under the ownership of Charles Vavrus and within the City of Palm Beach Gardens. These lands contain extensive wetlands that are adjacent to the Loxahatchee Slough to the east. The Acreage, a low-density residential area, is located directly to the south of the project site. The only access to the site at this time is an unpaved extension of Seminole Pratt-Whitney Road (SPW), connecting the site at its southwestern corner to the Acreage. THE PROPOSED PROJECT The subject application is for conceptual approval of the SWM system for the BRP and for construction and operation of Phase 1A of the project. All of the proposed Phase 1A construction will occur on the Mecca Farms site. The following, taken from the Staff Report, accurately describes the proposed project: The [BRP] is a phased multiple use development planned for approximately 1,919 acres and will consist of land uses related to science and technology, biotechnology, biomedical, and other related research and development industries and manufacturing. Additionally, proposed support and complementary land uses include educational, institutional, residential, commercial, and recreational facilities, along with utilities and a large created natural area. THE PROPOSED SWM SYSTEM The proposed SWM system will consist of several interconnected lakes that will provide wet detention for storm water runoff from the property site and from 39 acres of off- site flows from SPW Road and a proposed Florida Power and Light (FPL) Substation. The lakes will collect, store, and treat the runoff. The storm water will pass through the lakes, through a 247-acre area referred to as the “Natural Area” (which will be created as part of the mitigation plan), and discharged to the C-18 Canal. To provide additional water quality treatment, these lakes will include planted littoral zones and the southern lake will include a filter marsh. The Natural Area will, in subsequent construction phases, be constructed on the western boundary of the Mecca site with discharge to the C-18 canal, which is adjacent to the northern boundary of the Mecca Farms. The southern boundary of the Natural Area will be the north boundary of the lake that is to be constructed on the southern end of the property. This is the area that is available for use as a flow-way (which will be discussed in greater detail in a subsequent section of this Recommended Order). The Natural Area will be a wetland type system that will move water slowly through that system providing additional storage and water quality benefits prior to discharging through a gravity control structure into the C-18 Canal. The C-18 Canal discharges to either the Northwest or Southwest Fork of the Loxahatchee River, depending on how structures are operated downstream. Discharges travel in the C-18 Canal for approximately nine miles before reaching the Loxahatchee River. The existing SWM system for the Mecca Farms currently discharges to the C-18 Canal, as will the proposed SWM system. The proposed project will not discharge to the CWMA or the Hungryland Slough. The Grassy Waters Preserve and the Loxahatchee Slough are several miles from the project site and will not be affected by the project’s proposed activities. The following, which is taken from the Staff Report, accurately describes the proposed SWM system. The proposed conceptual surface water management system which will serve the 1,919-acre site will consist of site grading, storm water inlets and culverts which will direct all runoff to a series of interconnected lakes for water quality treatment and attenuation of the peak runoff rate. Pumps will control the runoff rate from the developed site into the adjacent onsite BRP natural area. The BRP natural area will discharge into the C-18 canal via a gravity control structure. The system has been designed to accommodate 39 acres of off-site flows from SPW [Road] and a proposed Florida Power and Light (FPL) Substation. The existing control elevation of the citrus grove is 17.0’ NGVD. The proposed control elevations are 18.0’ NGVD for the developed area and 19.0’ NGVD for the natural area. The control elevations are being raised to provide a “step down” of water elevations from wetlands to the north, west and east of the site (20.5’ to 21.0’) to lower elevations to the south (17.0’). PHASE 1A CONSTRUCTION The following, which is taken from the Staff Report, accurately describes the proposed Phase 1A construction: The Phase 1A construction activities will allow the applicant to proceed with lake excavation, clearing and site grading of 536 acres in the southern portion of the site. No permanent buildings or parking areas are proposed at this time. Stormwater from Phase 1A and the remainder of the site, to remain in agricultural use, will be treated in the Phase 1A lakes and then pumped into the existing impoundment for additional water quality treatment and attenuation prior to discharging to the west leg of the C-18 Canal via the existing weir structures. The existing 18,000 gpm pump that connects the on-site ditches and canals directly to the C-18 Canal will remain, but will only be used if the impoundment is full. (See Special Condition No. 21). Approval of Phase 1A authorizes the use of the existing, previously permitted surface water management facilities, therefore, the previous permit no. 50-00689-S is superceded by this permit. The 224 acre agricultural area east of the existing grove that is connected to the grove canal/ditch system will be severed as part of Phase 1A. The pipe connecting this area will be removed and portions of the berm around this area will be regraded so the area will sheetflow into the adjacent pasture land’s canal/ditch system as it did previously [sic] to being connected to the grove system. Of the 536 acres involved in the Phase 1A construction, 87 acres will become lake bottom and 449 acres will remain pervious area, subject only to grading. CONCEPTUAL APPROVAL Pertinent to this proceeding, Florida Administrative Code Rule 40E-4.021(5) defines the term “conceptual approval” to mean an ERP issued by the District which approves a conceptual master plan for a surface water management system or a mitigation bank. Florida Administrative Code Rule 40E-4.305, pertains to conceptual approvals and provides, in relevant part, as follows: Conceptual approvals constitute final District action and are binding to the extent that adequate data has been submitted for review by the applicant during the review process. A conceptual approval does not authorize construction, alteration, operation, maintenance, removal, or abandonment of a surface water management system or the establishment and operation of a mitigation bank. * * * For phased projects, the approval process must begin with an application for a conceptual approval which shall be the first permit issued for the project. An application for construction authorization of the first phase(s) may also be included as a part of the initial application. As the permittee desires to construct additional phases, new applications shall be processed as individual or standard general environmental resource permit applications pursuant to the conceptual approval. The conceptual approval, individual and standard general permits shall be modified in accordance with conditions contained in Chapters 40E-4 and 40E-40, F.A.C. Issuance of a conceptual approval permit pursuant to Chapter 40E-4, F.A.C., shall not relieve the applicant of any requirements for obtaining a permit to construct, alter, operate, maintain, remove, or abandon a surface water management system or establish or operate a mitigation bank, nor shall the conceptual approval permit applicant be relieved of the District’s informational requirements or the need to meet the standards of issuance of permits pursuant to Chapters 40E-4 or 40E-40, F.A.C. . . . PERMITTING CRITERIA In order to obtain an ERP, an applicant must satisfy the conditions for issuance set forth in Florida Administrative Code Rules 40E-4.301 and 40E-4.302. The conditions for issuance focus on water quantity criteria, environmental criteria, and water quality criteria. Florida Administrative Code Rule 40E-4.301 contains the following permitting conditions applicable to this proceeding: In order to obtain a standard general, individual, or conceptual approval permit ... an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal, or abandonment of a surface water management system: will not cause adverse water quantity impacts to receiving waters and adjacent lands; will not cause adverse flooding to on-site or off-site property; will not cause adverse impacts to existing surface water storage and conveyance capabilities; will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters; will not adversely affect the quality of receiving waters ...; will not cause adverse secondary impacts to the water resources; will not adversely impact the maintenance of surface or ground water levels or surface water flows ...; will not cause adverse impacts to a work of the District ...; will be capable, based on generally accepted engineering and scientific principles, of being performed and of functioning as proposed; will be conducted by an entity with the sufficient financial, legal and administrative capability to ensure that the activity will be undertaken in accordance with the terms and conditions of the permit, if issued; and will comply with any applicable special basin or geographic area criteria established in Chapter 40E-41 F.A.C. Florida Administrative Code Rule 40E-4.302 provides the following Additional Conditions for Issuance of Permits applicable to this proceeding: In addition to the conditions set forth in section 40E-4.301, F.A.C., in order to obtain a standard general, individual, or conceptual approval permit under this chapter or Chapter 40E-40, F.A.C., an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal, and abandonment of a system: Located in, on, or over wetlands or other surface waters will not be contrary to the public interest, or if such an activity significantly degrades or is within an Outstanding Florida Water, that the activity will be clearly in the public interest, as determined by balancing the following criteria as set forth in subsections 4.2.3 through 4.2.3.7 of the Basis of Review for Environmental Resource Permit Applications Within the South Florida Water Management District: Whether the activity will adversely affect the public health, safety or welfare or the property of others; Whether the activity will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the activity will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; Whether the activity will be of a temporary or permanent nature; Whether the activity will adversely affect or will enhance significant historical and archaeological resources under the provisions of Section 267.061, F.S.; and The current condition and relative value of functions being performed by areas affected by the proposed activity. Will not cause unacceptable cumulative impacts upon wetlands and other surface waters as set forth in subsections 4.2.8 through 4.2.8.2 of the Basis of Review. . . . THE BASIS OF REVIEW The District has adopted the BOR and incorporated it by reference by Florida Administrative Code Rule 40E- 4.091(1)(a). The standards and criteria found in the BOR are used to determine whether an applicant has given reasonable assurances that the conditions for issuance of an ERP have been satisfied. Section 1.3 of the BOR provides, in part, as follows: . . . Compliance with the criteria established herein [the BOR] constitutes a presumption that the project proposal is in conformance with the conditions for issuance set forth in Rules 40E-4.301 and 40E-4.302, F.A.C. WATER QUANTITY The term “control elevation” describes the level of freshwater water bodies established by a SWM system. The existing SWM system has a control elevation of 17’ NGVD. The control elevation for the proposed lake system will be raised to 18’ NGVD, and the control elevation for the proposed Natural Area will be raised to 19’ NGVD. Raising the control elevations will permit more treatment of storm water prior to discharge and will permit a more controlled discharge. In addition, raising the control elevation will lessen seepage onto the project site from adjacent wetlands. The Applicants provided reasonable assurances that the proposed project will not cause adverse water quantity impacts to receiving waters and adjacent lands, thereby satisfying the criteria set forth in Florida Administrative Code Rule 40E- 4.301(a). The Applicants provided reasonable assurances that the proposed project will not cause adverse flooding to on-site or off-site property, thereby satisfying the criteria set forth in Florida Administrative Code Rule 40E-4.301(b). The Applicants provided reasonable assurances that the proposed project will not cause adverse impacts to existing surface water storage and conveyance capabilities, thereby satisfying the criteria set forth in Florida Administrative Code Rule 40E-4.301(c). VALUE OF FUNCTIONS OF WETLANDS AND SURFACE WATERS Florida Administrative Code Rule 40E-4.301(d), requires the Applicants to establish that “. . . the construction, alteration, operation, maintenance, removal, or abandonment of a surface water management system . . .” “. . . will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters.” The District established that the term “value of functions,” as used in the rule, refers to habitat and life support functions. Because there are no wetlands or delineated surface waters on the Mecca Farms site, there are no direct adverse impacts to the functions that wetlands provide to fish and wildlife. The Applicants have provided reasonable assurances to demonstrate that the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters will not be adversely affected. The existing project site does not contain nesting areas for wetland-dependent endangered or threatened wildlife species or species of special concern. The potential for use of the existing project site for nesting by such species is minimal. The existing project site does contain habitat for the American Alligator and foraging habitat for wading birds and birds of prey. The primary foraging habitat on the existing site is around the perimeter of the existing 272-acre impoundment area in the northeast portion of the site. The existing impoundment will be replaced by on-site storm water treatment lakes and the BRP Natural Area that will have shallow banks planted with wetland plant species common to the area. Wildlife is opportunistic; and wading birds commonly feed in areas where there is water, wetland vegetation and wetland plants. The end result will be that the proposed project will have more and better foraging habitat acreage than the existing site. The Natural Area will provide a wetland buffer between the developed area and CWMA that will prevent any adverse impacts both to the wetlands and other surface waters in CWMA and to the value of the functions those wetlands and other surface waters provide to fish, wildlife, and listed species. The Natural Area will provide a wetland buffer between the developed area and Unit 11 that will prevent any adverse impacts both to the wetlands and other surface waters in Unit 11 and to the value of the functions those wetlands and other surface waters provide to fish, wildlife, and listed species. There was no competent evidence that the proposed project would impact the ability of the Florida Fish and Wildlife Conservation Commission to manage the CWMA through control burns or otherwise, thereby adversely affecting the diversity or abundance of fish and wildlife (including endangered species and their habitats). Petitioners attempted to raise the issue of mosquito control in their Petitions and at the Final Hearing. The allegations pertaining to mosquito control were struck by the District and Special Condition Number 26 was added before the Petitions were referred to DOAH. Petitioners made no attempt to amend their Petitions and have not challenged Special Condition 26. The Addendum to Staff Report (SFWMD Ex. 2) contains the following Special Condition Number 26: “Upon submittal of an application for construction of any buildings, the permittee shall submit a mosquito control plan for review and approval by District Staff.” Since there will be no buildings containing people or other facilities which would encourage the use of mosquito spraying, it is appropriate for the mosquito control condition to apply to only future phases of construction. There was no competent evidence of impacts attributable to pesticides associated with the application for the SWM system or for Phase 1A construction and operation that would adversely affect the diversity or abundance of fish and wildlife including endangered species and their habitats. The Applicants have satisfied the criteria set forth in Florida Administrative Code Rule 40E-4.301(d). WATER QUALITY The primary concern during Phase 1A construction will be erosion control. Best Management Practices (“BMPs”) are operational and design elements used to either eliminate or reduce the amount of pollutants at the source so they do not get into a SWM system or move downstream. To contain erosion in Phase 1A, the Applicants will use the following BMPs: Silt screens and turbidity barriers within existing ditches and around the perimeter of property. Planned construction sequencing to reduce movement and stock piling of material; Slope stabilization and seeding or sodding of graded areas; and Containment of construction materials with berms. All erosion and turbidity control measures will remain in place until the completion of the on-site construction and approval by the District’s post-permit compliance staff. The Applicants provided reasonable assurances that the proposed Phase 1A construction activities will not adversely impact the quality of receiving waters and that those activities will not violate State water quality standards. Section 5.2.1, BOR, requires that a SWM system provide wet detention for the first one inch of runoff. The proposed SWM system will provide wet detention for one and one-half inches of runoff. The Applicants provided reasonable assurances to demonstrate that the technical criteria in the BOR will be met. Under Section 1.3 of the BOR, compliance with the criteria in the BOR constitutes a presumption that the Proposed Project is in conformance with the conditions for issuance. This presumption was not rebutted by the Petitioners. The lake system will include planted littoral zones to provide additional uptake of pollutants. A filter marsh is also included in the southern lake. All of the storm water runoff from the lakes will pass through the filter marsh, which will be planted with wetland plants. The filter marsh will provide additional polishing of pollutants, uptake, and filtering through the plants. The discharge will then go into the BRP, which will provide the discharge additional uptake and filtering. BMPs utilized during the Operations and Maintenance phase will include regular maintenance inspections and cleaning of the SWM system, street-sweeping, litter control programs, roadway maintenance inspections and repair schedule, municipal waste collection, pollution prevention education programs, pesticides, herbicides and fertilizer storage, and application training and education. The littoral zones, filter marsh, BRP natural area, and BMPs were not included in the water quality calculations and are over and above rule requirements. The Applicants provided reasonable assurances to demonstrate that the proposed project will not adversely affect the quality of receiving waters. Therefore, Rule 40E- 4.301(1)(e), F.A.C., will be satisfied and water quality standards will not be violated. HAZARDOUS SUBSTANCES Pursuant to Section 5.5.5 of the BOR, commercial or industrial zoned projects shall provide at least one-half inch of dry detention or retention pretreatment as part of the required retention/detention, unless reasonable assurances can be offered that hazardous materials will not enter the project's SWM system. The Addendum to Staff Report reflects the following Special Condition 25 pertaining to hazardous materials: Upon submittal of an application for construction of commercial or industrial uses the permittee shall submit a plan that provides reasonable assurances that hazardous materials will not enter the surface water management system pursuant to the requirements of section 5.2.2(a) of the Basis of Review. Applicable permitting criteria does not require the Applicants to present a hazardous substances plan at this point because no facilities that will contain hazardous materials are part of the Phase 1A construction. SECONDARY IMPACTS Florida Administrative Code Rule 40E-4.301(1)(f) and Section 4.1.1(f) of the BOR, require an applicant to provide reasonable assurances that the proposed activities will not cause adverse secondary impacts to the water resources. A secondary impact is an indirect effect of a project resulting in adverse effects to wetlands or other surface waters. The District considers those adverse effects that would not occur "but for" the activities that are closely linked and causally related to the activity under review. This standard is discussed further in the Conclusions of Law section of this Recommended Order. The County’s Exhibit 3 is a secondary impact analysis identifying the secondary impacts that may potentially result from the proposed project. These impacts are: 1) the widening of SPW Road; 2) the construction of an FPL substation; 3) the extension of PGA Boulevard; and 4) the potential relocation of a runway at North County Airport. The secondary impact analysis performed pursuant to the Uniform Mitigation Assessment Method (UMAM) contained in Florida Administrative Code Chapter 62-345 reflects that up to 153.3 acres of wetlands may be partially or completely impacted by these secondary impacts, resulting in approximately 71.21 units of functional loss. Where future activities are expected to directly impact wetlands, secondary impacts were assessed based on the loss of all current functional value within the direct footprint of that activity. Additionally, an assessment was conducted to determine the degree of partial functional loss where impacts beyond the footprint of these activities are anticipated. SPW Road is an existing dirt road which is in the County's five-year road plan to widen as a four-lane paved road. Because the widening of the existing dirt road to a four-lane paved road is part of the five-year road plan, the impacts of that widening are not attributable to the subject project. However, as part of the proposed project, it is proposed to widen SPW Road to a six-lane paved road. The additional impacts associated with the widening from four to six lanes will be caused by, and are linked to, the proposed project. These impacts amount to approximately 2.2 acres. The FPL substation, which is proposed to service the proposed project, may result in 1.6 acres of potential direct impacts to wetlands. In addition, 1.0 acre of potential indirect secondary impacts may occur to wetlands that are not going to be dredged and filled. Those indirect secondary impacts may have some adverse impact on the functional value to those wetlands for wildlife utilization. The extension of PGA Boulevard to the Mecca Farms site has the potential to result in 45.6 acres of direct impacts to wetlands and 56.6 acres of indirect secondary wetland impacts which will not be dredged or filled, but will be in close proximity to the road. The secondary impact assessment for PGA Boulevard assumed the incorporation of wildlife crossings to minimize habitat fragmentation. If the airport runway needs to be shifted, potential direct wetland impacts to an additional 22.7 acres may occur. Indirect impacts to 23.6 acres of wetlands in close proximity could also occur. Runway relocation may or may not be necessary due to the PGA Boulevard extension; however, the analysis assumed the need for the relocation. Each of the projects listed above as potential secondary impacts will require a separate construction and operation permit from the District. The issuance of this permit does not in any way guarantee the issuance of permits for any of these identified potential secondary impacts. MITIGATION PLAN The Applicants provided a conceptual mitigation plan using UMAM to demonstrate how potential secondary impacts could be offset. Mitigation options have the potential to provide more than twice the functional gain than the functional loss from the identified secondary impacts. The conceptual mitigation options include: 194 acres of the land that had been acquired for future mitigation needs in Unit 11. 227 acres of the BRP natural area. 32.6 acres in the southern lake wetland along with proposed upland habitat. Sufficient mitigation is available in these options to offset the potential secondary impacts. The mitigation for the four potential secondary impacts is not required to be implemented now because the impacts are not occurring now. Section 4.2.7 of the BOR requires that the District consider those future impacts now and that a conceptual mitigation plan be provided to demonstrate and provide reasonable assurances that those impacts, in fact, can be offset in the future. The Governor and Cabinet sitting as the Board of Trustees considered and approved a request for public easement of approximately 30 acres to use a portion of CWMA for SPW Road, an FPL substation, and the land area that may be needed by District in the future for the connection to the flow-way. As consideration in exchange for the public easement over 30 acres, the County will transfer fee simple title of 60 acres to the State. This public easement also provides a benefit for CERP as it includes the small portion that the District is going to need for its future CERP project to connect to the flow-way on the proposed project site. The Applicants provided reasonable assurances that mitigation will offset secondary impacts to wetlands and other surface waters. UNIDENTIFIED SECONDARY IMPACTS Testimony at the final hearing raised a question as to whether there is nesting or roosting by listed wading bird species in adjacent off-site wetlands outside the eastern boundary of the project site. Evidence was inconclusive on nesting or roosting in these areas. Because the status of adjacent listed wading bird nesting or roosting is uncertain, the District suggested in its Proposed Recommended Order that a special condition requiring a wildlife survey prior to construction near the eastern project boundary be added to the permit as follows: Prior to application for construction within 1000 feet of the eastern boundary of the above-ground impoundment, the applicant shall conduct a wildlife survey to identify any nesting or roosting areas in the adjoining off-site wetlands utilized by listed species of wading birds. If such nesting or roosting areas are found the permittee shall, if determined necessary by the District, incorporate additional buffers or other appropriate measures to ensure protection of these wetland functions. The District represented in its Proposed Recommended Order that the County has no objection to adding the foregoing condition. CUMULATIVE IMPACTS Pursuant to Section 373.414(8), Florida Statutes, the District is required to consider cumulative impacts upon wetlands and other surface waters delineated in Section 373.421(1), Florida Statutes, within the same drainage basin. Cumulative impacts are the summation of unmitigated wetland impacts within a drainage basin. The cumulative impact analysis is geographically based upon the drainage basins described in Figure 4.2.8-1 of the BOR. Cumulative impacts are unacceptable when they would result in unacceptable adverse impacts to the functions of wetlands and surface waters within a drainage basin. There are no wetlands or other surface waters delineated pursuant to Section 373.421(1), Florida Statutes, on the Mecca Farms site. Therefore, no cumulative impacts are created by the direct impacts of the project. Cumulative impacts may be created by a project's secondary impacts. If a wetland impact has been appropriately mitigated on-site within the drainage basin, there is no residual impact, and therefore no cumulative impact. The PGA Boulevard extension, a portion of the SPW Road widening, and the airport runway relocation are located within the C-18 Basin. The proposed mitigation options are all located in the C-18 Basin and will offset those impacts. Those potential secondary impacts are considered to meet the cumulative impact requirements of Section 373.414(8), Florida Statutes. The Applicants provided reasonable assurances that the proposed project will not result in cumulative impacts to the C-18 Basin. The FPL substation is located within the L-8 Drainage Basin. The majority of the SPW Road expansion is located within the C-18 Basin, but a portion is located on the basin line between the C-18 Basin and the L-8 Basin. Because the mitigation for the L-8 impacts are proposed in a different basin, the Applicants were required to conduct a cumulative impact analysis for the L-8 Basin impacts. Based on the Florida Land Use Cover Classification System, there are 43,457 acres of freshwater wetlands within the L-8 Basin. Approximately 41,000 acres of the wetlands in L-8 Basin are in public ownership. This total constitutes approximately 95 percent of all the wetlands in the L-8 Basin. Public ownership of these wetlands provide a high level of assurance that these lands will be protected in perpetuity. The Respondents established that proposed mitigation can fully offset the potential impacts from the SPW Road expansion and the FPL substation and the approximately four acres of impacted wetlands in the L-8 Basin. The Applicants provided reasonable assurances that there are no unacceptable adverse cumulative impacts on the L-8 Basin.4 GROUND WATER FLOWS, SURFACE WATER FLOWS, AND MINIMUM FLOWS AND LEVELS Florida Administrative Code Rule 40E-4.301(1)(g) requires an applicant to provide reasonable assurances that the proposed activity will not adversely impact the maintenance of surface or ground water levels or surface water flows established pursuant to Section 373.042, Florida Statutes. The term "maintenance of surface and groundwater levels or surface water flows" in Florida Administrative Code Rule 40E-4.301(1)(g) means that a project will not adversely impact the maintenance of surface water flows that contribute to meeting the minimum flow for the water body. An adverse impact to the maintenance of surface or groundwater levels or surface water flows may occur when a project discharging to a water body with a designated minimum flow level is proposed to be diverted. An analysis was done to compare the peak discharge rate from the existing SWM system on the Mecca Farms site with the projected peak discharge rate from the proposed SWM system. The analysis showed that the peak discharge rate under the proposed system will be less than that of the existing system. That result was expected since the proposed system will have higher control elevations, which, as noted above, will provide better treatment and permit a better control of the discharge into the C-18 Canal. Under the existing SWM system, storm event water in a dry period is frequently stored in the existing impoundment for future irrigation purposes. Under the proposed SWM system such storm event water will be discharged downstream, which will benefit those downstream areas during dry periods. The proposed system will also provide better control over pulse discharges during heavy storm events. The Applicants provided reasonable assurances that the proposed activities will not adversely impact the maintenance of surface or ground levels or surface water flows as required by Florida Administrative Code Rule 40E-4.301(1)(g). THE DISTRICT’S OBJECTIVES Sections 373.414 and 373.416, Florida Statutes, require an applicant to provide reasonable assurances that a regulated activity will not be harmful to the water resources and will not be inconsistent with the overall objectives of the District. Congress initially authorized the Central and Southern Florida (“C&SF”) Project in 1948. Thereafter extensive work was undertaken pertaining to flood control; water supply for municipal, industrial, and agricultural uses; prevention of saltwater intrusion; and protection of fish and wildlife. The work included construction of a primary system of 1000 miles each of levees and canals, 150 water-control structures, and 16 major pump stations. Unintended consequences of the C&SF Project have included the irreversible loss of vast areas of wetlands, including half of the original Everglades; the alteration in the water storage, timing, and flow capacities of natural drainage systems; and the degradation of water quality and habitat due to over-drainage or extreme fluctuations in the timing and delivery of fresh water into the coastal wetlands and estuaries. In 1992, Congress authorized the C&SF Project Comprehensive Review Study, which is generally referred to as the “Restudy.” The objective of the Restudy was to reexamine the C&SF Project to determine the feasibility of modifying the project to restore the South Florida ecosystem and provide for the other water-related needs of the region, such as water supply and flood protection. In April 1999, the U.S. Army Corps of Engineers issued the Central and Southern Florida Project Comprehensive Review Study Final Integrated Feasibility Report and Programmatic Environmental Impact Statement (“Restudy Report”). The Restudy Report recommends a comprehensive plan for the restoration, protection, and preservation of the water resources of Central and South Florida. The resulting plan is known as CERP. The North Palm Beach County Part I project, which includes restoration of the Northwest Fork of the Loxahatchee River (“NWFLR”), is a component of CERP. The successful completion of CERP and the successful restoration of the NWFLR are high-priority objectives of the District. The Loxahatchee River is an important feature of the South Florida ecosystem, nationally and internationally unique, and an important natural and economic resource. Rules pertaining to MFL for the NWFLR and for the recovery of the NWFLR are found at Florida Administrative Code Rule 40E-8.011; 40E-8.221(4); and 40E-8.421. Recovery goals, which are not presently being met, have been established; and strategies to meet those goals have been identified. The Mecca Farms site is located within the boundaries of the CERP North Palm Beach County Part I project and has the potential to affect CERP and the restoration of the NWFLR. Projects that potentially would affect or would be within or adjacent to a CERP project are evaluated on a case-by- case basis to determine whether a proposed project would not be inconsistent with CERP and other District objectives. There was a dispute between Respondents and Petitioners as to whether the proposed project was inconsistent with the District’s objectives, including CERP and its goals pertaining to the restoration of the NWFLR. Petitioners contend that the District has insufficient evidence that the Mecca Farms will not be needed for the construction of a reservoir. That contention is rejected. The greater weight of the credible evidence established that sufficient storage is available at a superior site known as the Palm Beach Aggregates (PBA) site in the L-8 Basin, which is a unique geological site that will provide in-ground storage of water.5 Water from the PBA storage site can be conveyed to the NWFLR to increase dry season flows. Water can be stored at the PBA site in the wet season to prevent potentially damaging high flows. The L-8 Basin, which is adjacent to the C-18 Basin, receives more water during the wet season than it uses. This means that at present a significant amount of water must be discharged to tide (lost) during the wet season to provide for flood protection in this area. As envisioned, the water currently lost to tide could be stored at the PBA site for use during the dry season. By combining the water storage in the L-8 Basin with connective flow-ways to the C-18 Canal, water demands within the C-18 Basin, including the NWFLR, can also be met by the PBA storage site.6 An increase in freshwater flows to the NWFLR will further the District’s restoration goals for the NWFLR. Storage at PBA has regional benefits for other significant natural areas because it will provide additional flows to the Loxahatchee Slough and Grassy Waters Preserve. Those additional flows will further the District’s CERP goals. Since October of 2003, County staff and the District’s ERP staff have coordinated review of the subject project with the District’s CERP Planning and Federal Projects Division and other District staff working on projects in this region. The County asked the District to determine if the Mecca Farms’ site could in some way accommodate CERP objectives, and three alternatives were considered: 1) no action; 2) a reservoir; and 3) a flow-way. As opposed to a reservoir, the more valuable and the more practical, use of the Mecca Farms site would be as part of the system to convey the stored water to the areas that would most benefit from its discharge. The proposed flow-way in the BRP Natural Area would be an integral part of that conveyance system and would provide the District with greater flexibility in managing and directing the discharge of the water stored at the PBA site. Prior to the development of the flow-way concept as part of the proposed development, CERP identified a single route to take water from PBA to the NWFLR. The flow-way will provide an additional route from PBA to the NWFLR. That additional route will provide the District with greater operational flexibility. The flow-way will complement the L-8 Basin flow- way and help reduce peak flows to the NWFLR and the Estuary. The flow-way also provides a potential route allowing excess water to be brought back from the C-18 Basin to the PBA site for storage. There are no other potential routes that allow water to be directed from the C-18 Basin in the wet season to the PBA site. The flow-way provides a feature that was not part of the CERP original plan and is therefore an unanticipated benefit for CERP. The Applicants provided reasonable assurances that the proposed project is not inconsistent with the District’s objectives.7
Recommendation Based on the foregoing findings of fact and conclusions of Law, it is RECOMMENDED that the District issue the subject ERP for the conceptual approval of the SWM system for the BRP and the Phase 1A construction and operation subject to the general and special conditions set forth in the Staff Report and the Amended Staff Report. It is further RECOMMENDED that the District add the following special condition: Prior to application for construction within 1000 feet of the eastern boundary of the above-ground impoundment, the applicants shall conduct a wildlife survey to identify any nesting or roosting areas in the adjoining off-site wetlands utilized by listed species of wading birds. If such nesting or roosting areas are found the permittee shall, if determined necessary by the District, incorporate additional buffers or other appropriate measures to ensure protection of these wetland functions.
