Findings Of Fact The petitioner is a private landowner of a tract of land adjacent to the Suwannee River in Dixie County, Florida. The Respondent, State of Florida, Department of Environmental Regulation, is an agency of the State of Florida charged with carrying out the mandates of Chapter 403, Florida Statutes, and the rules contained in the Florida Administrative Code promulgated thereunder. The Petitioner's proposed project entails the construction of a twelve- foot wide filled road across approximately 270 feet of swampy area in which the dominant plant species is bald cypress (taxodium distichum), a species listed in Rule 17-4.02(17), Florida Administrative Code. The property to be so developed by the petitioner lies within the landward extent of the Suwannee River in Dixie County. The Suwannee River, in this project area, constitutes waters of the state over which the Department has dredge and fill permitting jurisdiction pursuant to Rule 17-4.28(a), Florida Administrative Code. The project areas within "outstanding Florida waters" as defined in Rule 17-3.04(1)(3)g, Florida Administrative Code. The "upland berm" or river terrace on the property immediately adjacent to the navigable portion of the river is caused by the natural alluvial deposition of the river and the landward extent of the state waters here involved crosses the property in approximately the center of the parcel. The proposed filing for the road crossing the swamp would result in the permanent elimination of at least 3,240 square feet of area within the landward extent of the Suwannee River. Specifically, the project would consist of a road some 12 feet wide at the bottom and 8 feet wide at the top, extending approximately 270 feet across the swampy area in question from the portion of the property which fronts on a public road, to the river terrace or "berm" area along the navigable portion of the Suwannee River. The road will be constructed with approximately 450 cubic yards of clean fill material with culverts 12 feet in length and 3 feet in diameter placed under the road at 25 foot intervals. The parties have stipulated that the Department has jurisdiction pursuant to Chapter 403, Florida Statutes, and Public Law 92-500, to require a permit and water quality certification or the construction of a stationary installation within the waters of the state which this project has been stipulated to be. The area to be filled is primarily vegetated by bald cypress, ash, blackgum, planer trees and other swamp species falling within the definitional portion of the above rule. The swamp contributes to the maintenance of water quality in the river itself by the filtering of sediment and particulates, assimilating and transforming nutrients and other pollutants through the uptake action of the plant species growing therein. The proposed project would destroy by removal, and by the filling, a substantial number of these species on the site which perform this function. The swamp area also serves as a habitat, food source and breeding ground for various forms of fish and wildlife including a species of state concern, the yellow-crowned night heron, which has been observed on this site and which requires such habitat for breeding and for its food source (see the testimony of Kautz). The area in question provides flood protection by storing flood waters and releasing them in a gradual fashion to the river system, especially during dry periods when the river level is lower than that of the swamp which serves to augment stream flow in such periods. As established by witness Kautz, as well as witnesses Rector and Tyler, the filling proposed by the Petitioner would cause degradation of local water quality within the immediate area where the fill would be placed and, the attendant construction activity adjacent to either side of the filled area would disturb trees, animals and other local biota. The period during and immediately after the construction on the site would be characterized by excessive turbidity and resultant degradation of the water quality within the area and downstream of it. The long-term impact of the project would include continued turbidity adjacent to and downstream from the filled road due to sloughing off of the sides of the road caused by an excessively steep slope and to the necessary maintenance operations required to re-establish the road after washouts caused by each rain or rainy period. An additional long-term detrimental effect will be excessive nutrient enrichment expected in the area due to the removal of the filtrative functions caused by removal of the trees and other plant life across the entire width of the swamp and the resultant inability of the adjacent areas to take up the nutrient load formerly assimilated by the plant life on the project area. The project will thus permanently eradicate the subject area's filtrative and assimilative capacity for nutrients, heavy metals and other pollutants. The effect of this project, as well as the cumulative effect of many such already existent fill roads in this vicinity along the Suwannee River, and the effect of proliferation of such filling, will cause significant degradation of local water quality in violation of state standards. The effect of even this single filled road across the subject swamp is especially severe in terms of its "damming" effect (even with culverts). The resultant retention of water standing in the swamp for excessive periods of time will grossly alter the "hydro period" of the area or the length of time the area is alternately inundated with floodwaters or drained of them. This will cause a severe detrimental effect on various forms of plant and animal life and biological processes necessary to maintenance of adequate water quality in the swamp and in its discharge to the river itself. The excessive retention of floodwaters caused by this damming effect will ultimately result in the death of many of the tree species necessary for the uptake of nutrients and other pollutants which can only tolerate the naturally intermittent and brief flood periods. This permit is not necessary in order for the Petitioner to have access to his property as his parcel fronts on a public access road. The purpose of the proposed road is merely to provide access to the river terrace or "upland berm" area on the portion of the property immediately adjacent to the navigable waters of the Suwannee River. The Department advocated through its various witnesses that a viable and acceptable alternative would be the construction of a walkway or a bridge on pilings across the jurisdictional area in question connecting the two upland portions of Petitioner's property. Such a walkway would also require a permit, but the Department took the position that it would not object to the permitting of an elevated wooden walkway or bridge for vehicles. The petitioner, near the close of the hearing, ultimately agreed that construction of such a walkway or bridge would comport with his wishes and intentions for access to the river berm portion of his property and generally indicated that that approach would be acceptable to him. It should also be pointed out that access is readily available to the waterward portion of the property from the navigable waters of the river by boat. The Petitioner did not refute the evidence propounded by the Department's expert witnesses, but testified that he desired the fill-road alternative because he believed it to be somewhat less expensive than construction of an elevated wooden bridge or walkway and that he had been of the belief that the use of treated pilings for such a walkway or bridge would result in chemical pollution of the state waters in question. The expert testimony propounded by the Respondent, however, establishes that any leaching action of the chemical in treated pilings would have a negligible effect on any life forms in the subject state waters at any measurable distance from the pilings. In summary, the petitioner, although he did not stipulate to amend his petition to allow for construction of the bridge as opposed to the fill road, did not disagree with it as a viable solution and indicated willingness to effect establishment of access to the riverfront portion of his property by that alternative should it be permitted.
Findings Of Fact Petitioner James C. Dougherty owns property known as Buccaneer Point, which is a peninsula on the western side of Key Largo, Florida. This property is also known as Buccaneer Point Estates, and is a residential subdivision. On June 26, 1979, the Petitioner individually and as a trustee, applied to the Respondent for a permit to conduct dredging and filling activities at the aforementioned property, in particular, the project contemplated dredging access channels in Florida Bay and Buttonwood Sound and the connection of two existing inland lakes on the property site to those water bodies. After review, the Respondent denied the permit request and asserted permit jurisdiction in keeping with Chapters 253 and 403, Florida Statutes, and associated regulatory provisions found in the Florida Administrative Code. Having been denied the permit, the Petitioner requested a formal hearing to consider the matters in dispute and a hearing was conducted on the dates alluded to in this Recommended Order. The hearing was conducted in keeping with Subsection 120.57(1), Florida Statutes. The denial of the permit request was in the form of a letter of intent to deny dated May 27, 1980. See Petitioner's Exhibit No. 4, admitted into evidence. Following the receipt of the letter of intent to deny, the Petitioner commenced a series of revisions to the project leading to the present permit request which is generally described in Petitioner's Exhibit No. 6, admitted into evidence. If the project were allowed, it would call for the dredging of access channels in Florida Bay and Buttonwood Sound, those channels to be 75 feet long and -5 feet N.G.V.D., with side slopes of 1:3. Additional inland canals would be dredged to connect the access channels with the interior lakes, the north channel being 100 feet wide -6 feet N.G.V.D. and 400 feet long, and the south canal being 62 feet wide -6 feet N.G.V.D., and 225 feet long. Side slopes of the canals would be 1:3. The project also intends the connection of the two interior lakes by the excavation of a 162-foot long by 50-foot wide connection or plug at a depth of -5 feet N.G.V.D. The material from this excavation of the plug would be used as ton soil on the uplands. Finally, the permit proposes the shoaling of the North Lake on the property to -15 feet N.G.V.D. by the use of clean limerock fill. Through its opposition to the project, the Respondent has indicated concerns that bay grass beds would be damaged over the long term by boats as a result of the dredging of proposed channels and canals; a concern about increased BOD demands which would lower water quality following the long-term accumulation of organic materials in the channels. The Department also contends that construction of the south channel would destroy productive grass beds and "vegetated littoral shallows," which now serve as a nursery and feeding ground for numerous invertebrates. Respondent believes that the north channel would eliminate an area of mangrove wetlands which filters nutrients and toxic materials and serves as a nursery and feeding ground for estuarine organisms and wading birds. The Respondent also feels that the north channel would disturb a stable mangrove humus peat band, which now supports large numbers of invertebrates and which band extends along the northern shoreline of Buccaneer Point. The Department, in discussing the acceptability of the permit, has expressed concern that bottoms adjacent to the north channel would be harmed by increased erosion and sedimentation of the disturbed mangrove peat. Respondent has further stated that water in both interior lakes is now in violation of water quality standards and that water quality data shows high oxygen demands. The Respondent has put at issue the Petitioner's hydrographic report on the flow-through lake system, citing what it believes to be errors in the report. The Respondent has expressed specific concern about water quality standards as set forth in the following rules: Rule 17-3.121(5), Florida Administrative Code, Bacteriological Quality; Rule 17-3.121(7), Florida Administrative Code, Biological Integrity; Rule 17-3.061(2)(b) Florida Administrative Code, BOD; Rule 17-3.121(14), Florida Administrative Code, Dissolved Oxygen; Rule 17-3.121(20), Florida Administrative Code, Nutrients; Rule 17-3.061(2)(j) Florida Administrative Code, Oils and Greases; Rule 17- 3.061(2)(1), Florida Administrative Code, Phenolic Compounds; Rule 17-3.121(28), Florida Administrative Code, Transparency; and Rule 17-3.061(2)(a), Florida Administrative Code, Substances. The Respondent indicated that it felt the project would be adverse to the public interest because it would cause erosion, shoaling, or creation of stagnated areas of water, would interfere with the conservation of fish, marine life and wildlife or other natural resources, and would result in the destruction of oyster beds, clam beds or marine productivity, including destruction of natural marine habitats or grass flats suitable as nurseries or feeding grounds for marine life, including established marine soils which are suitable for producing plant growth of a type useful as nursery or feeding grounds for marine life. The project was also thought by the Department to be not in the public interest because it would reduce the capability of the habitat to support a well-balanced fish and wildlife population because it would impair the management or feasibility of management of fish and wildlife resources. The Petitioner has employed hydrographic engineers to conduct a study of the flushing characteristics of the system, should the access channels, canals and interior connections be allowed. It is an undertaking on the part of the Petitioner dealing with physical characteristics of the waterway and the forcing conditions in and around the site, which include tidal flow, wind-driven flow and mean sea level changes. The two State water bodies at the site, Buttonwood Sound and Florida Bay, are separated by the project site and other islands at the northern tip of the project. The effects of this separation changes the arrival time of high tide at the northern and southern extremities of the project site promoting a mean sea level surface difference between Buttonwood Sound and Florida Bay. The sea level difference or "head" assists in generating flow in the sense of moving the water from the high to the low elevation. To gain an exact measure of the hydraulic head, tidal gauges were placed at the northern entrance channel and in the southern entrance channel. The use of these gauges over a period of time allowed the determination of the spring and neap tide conditions. The "head" differences finally arrived at by calculations by the Petitioner's experts assisted in the creation of a mathematical model to determine flows in the water system. This lead to an estimate of flushing time of 2 1/2 days. See Petitioner's Exhibits 7-9,admitted into evidence. In turn, an estimation was made that approximately half of the flow which presently flows through Baker Cut, at the project site, would be diverted to the waterway system if constructed and this in conjunction with other calculations led to the conclusion that the flushing time was 3 to 4 days as opposed to the 2 1/2 days arrived at by the mathematical system. See Petitioner's Exhibit 10, admitted into evidence. The estimate of 3 to 4 days was the more current study and was premised upon conditions of an adverse south, southeast wind which would cause the water to move north, absent current conditions, as opposed to this south direction which was the normal direction of movement. The Petitioner also examined the flushing characteristics of similar projects which were not as favorable because of a lack of "head" differences which assisted in the flow of the water. Based upon the results of the studies conducted by Petitioner's experts, the flushing time of the system is found to be 3 to 4 days. While there is some correlation between a short flushing time for a water system and the water quality within that system, examination of other channel systems in the Florida Keys indicates that short flushing times do not always cause the waters to meet State water quality standards. For that reason, water quality considerations must be dealt with bearing in mind the physical characteristics of the system extant and as proposed using flushing time as a part of the equation. Those specific water quality criteria will be addressed in subsequent portions of these findings. Tests conducted by the parties dealt with the amount of dissolved oxygen in waters at the project site, and revealed dissolved oxygen levels of less than 4 parts per million, even when testing at depths less than 15 feet. This condition is one which is not unusual for natural water systems which have remarkable stability and are not the subject of flow or flushing, as example in mangrove forests. If the system were open, dissolved oxygen levels in the interior lakes would improve, though not necessarily to a level which no longer violates State water quality considerations related to dissolved oxygen levels. On the related subject of BOD or biochemical oxygen demand, that demand placed on oxygen in the water biochemicals or organic materials, the system as it exists and as proposed does not appear to cause excessive BOD, notwithstanding an 8 to 12 foot wide band of peat substrate in the area of the North Lake wall. Although the biochemical oxygen demand related to the layer of peat in the lake's system in its present state presents no difficulty, if the water system were open this peat layer would cause a significant amount of loading of biochemical oxygen demand in the lake system and eventually the surrounding water bodies. On the question of nutrients in the marine system, reflected by levels of phosphorus and nitrogen or variations impact the compensation point for the North Lake. In fact, there would be improvement in transparency or clarity for both lakes. Nonetheless, in the short run, the turbidity problems associated with the placement of clean limerock fill over the flocculent peat material would violate the transparency standard in that location. On the subject of toxic substances, meaning synthetic organics or heavy metals in sea water, tests by the Petitioner at the project site and comparison site demonstrated that those substances would not exceed the criterion related to those materials. On the subject of fecal coliform bacteria, water quality samples were taken at the project site and a comparison site. The residences now at the project site and those at a development known as Private Park use septic tanks. In view of the porous nature of the limerock foundation upon which the residences are built and in which the septic tanks are placed, the possibility exists for horizontal movement of the leachate into surrounding waters of the project site and the landlocked lakes; however, this movement is not dependent upon the opening of a flow-through system at the project site. Moreover, tests that were conducted in the comparison site and project site reveal less than one fecal coliform bacterium per 100 milliliters and if the system were open, the circulation in the lakes would lower the residence time of leachate. In describing the habitat afforded by the interior lakes as they now exist, the North Lake does not afford animals or fish the opportunity to colonize, because there are no areas where they may disappear into the lake. This limits the opportunity for habitat to those animals who have their entire life cycle in a landlocked system, and necessarily of those substances in the water, water quality standards for nutrients will not be substantially altered by the proposed project. In other words, the project will not cause an imbalance in natural aquatic flora or fauna population, by way of advent of phytoplankton bloom leading to eutrophy. The nutrient samples taken in the interior lakes demonstrate normal sea water levels and those levels outside the lake were low and the flow-through system is not expected to raise nutrient levels. Sampling for oils and greases in the comparison waterways where residential development had occurred in the lakes and ambient waters at the site, did not indicate problems with those substances in the sense of violation of State water quality standards. Sampling for phenolic compounds at the comparison sites and at the lakes and ambient waters at the project site showed less than .001 micrograms per liter in each instance of the sample. There are no sources or potential sources of phenols at the site. On the question of the State water quality dealing with transparency, that standard requires that the level of the compensation point for photosynthetic activity shall not be reduced by more than ten percent (10 percent) compared to natural background levels. The compensation point for photosynthetic activity is the level at which plant and animal respiration and photosynthetic activity are equal. In static state, the Petitioner's analysis of this criterion revealed that the North Lake compensation point would be below 15 feet and the South Lake would have no compensation point, due to its shallow nature. In the long run, the opening of the proposed connections in the planned development together with the shoaling, would not negatively excludes animals with a long larva stage. Examination of comparison sites pointed out the possibility for colonization at the project site should the waterways be opened. Specific testing that was done related to colonization by fishes, in particular sport and commercial fishes, demonstrated that those species increased in richness, density and diversity if a system was opened by channels and canals. In addition, the comparison of this project site and systems similar to that contemplated by the open waterway indicated that sea grasses would increase after a period of years if the system were open. Sampling was conducted in substrates to gain some understanding of the effect of the proposed project on the Shannon Weaver Index, i.e., whether there would be a reduction by less than 75 percent of established background levels. Although there would be no problem with the biological integrity standard related to South Lake and its waterway, the North Lake and waterway system could be expected to be in violation of that index due to the present circumstance as contrasted with that circumstance at the point when water flowed through. If the waters were opened to the project site, marine biological systems on the outside of the interior lakes would be given an opportunity to use those lakes as a nursery ground or spawning site for fishes, a refuge in cold weather conditions and a site for predators to find prey. If the lakes were opened to the outlying areas, alga, grass populations, mobile invertebra, plankton and other forms of life could utilize the interior lakes. In the area where the north canal or inland canal would be placed are found red mangroves (Rhizophora mangle) and black mangroves (Avicennia germinas) . The mangroves are frequently inundated by tidal waters and are the most mature and productive of the mangroves which are found at the property site. Some of those mangroves are located waterward of the line of mean high water and would be removed if the project is permitted. The mangroves at the project site provide filtration of sediments and nutrients contained in stormwater runoff from adjacent upland areas, as well as from tidal flows. This filtering process is an essential part of the maintenance of water quality in the adjacent open bay estuarine or marine system. Nutrients in the tidal waters, as well as runoff waters, are settled out and in the sediments retained by the mangrove roots and are transformed into vegetative leaf matter by the mangroves as they live and grow. The root systems of the mangroves and their associated vegetation provide stabilization of estuarine shoreline sediments and attenuation of storm-generated tides. These mangrove wetlands provide unique and irreplaceable habitats for a wide variety of marine as well as upland wildlife species. The mangroves also contribute leaf or detrital matter to the surrounding State waters and estuarine system in the form of decayed leaf litter. This organic component forms the basis of the marine food chain and is used directly for food by a variety of marine organisms, including small fish. Commercial and sports fish species feed directly on the mangrove detritous or on the fish or other forms of marine life that feed on that detrital matter. In removing the mangroves, the applicant causes a loss of the function which those plants provide in the way of filtration and the promotion of higher water quality and causes biological impact on marine organisms, to include sports and commercial fishes. In the area of the north access channel, there exists a band of stable mangrove peat which is 50 to 75 feet wide and one to two feet thick. Waterward of this expanse of humus is located a sandy bottom vegetated by turtle grass and other sea grasses and alga. The turtle grass in the area of the proposed north channel serves as a nursery and feeding ground for a rich and diverse aquatic community, including species of oysters, clams and other mollusks, as well as commercial and sports fish. This grass also filters and assimilates contaminants in the water column and serves to stabilize sediments to prevent turbidity. Dredging would destroy the turtle grass beds and their functions. These impacts on mangroves and sea grasses are significant matters, notwithstanding the fact that the possibility exists that mangroves would repopulate in the area of the north channel and North Lake, together with the repopulation of sea grasses in that area after a period of years. The south waterway would cause the removal of certain sea grasses, which could be expected to revegetate. Moreover, at present, the sea grasses in this area are sparse due to the shallow waters in that area, which waters are too warm for sea grasses to thrive. Construction of the access channel would result in increased erosion and sedimentation based upon boat wake wash and in turn allow for adverse impact on the biologically productive bay bottom. Water quality degradation can be anticipated because of the erosion and leaching of dissolved particulate material from the disturbed peat band at the shoreline and into shallow waters in the bay and into the North Lake. Transition from the inland channels to the bay side access channels at the north and south will be box cut at the mean high water line and in view of the fact that the inland channels are 100 feet wide and the bay side access channels are only 50 feet wide, erosion can be expected, causing turbidity.
The Issue The issue in this case is whether the development order issued by Polk County for Robert Crowder's development known as Paradise Country Estates complies with Chapter 380, Fla. Stat. (1991). The Department of Community Affairs' Petition for Appeal of Development Order (the DCA Petition) alleges that the development order is contrary to Polk County's 1985 comprehensive plan for the following reasons: Paragraph 11 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 9, Objective III, "Natural Resources," of the Land Use Element (LUE) of the 1985 Plan. Policy 9 states: "Structures should be placed in a manner which will not adversely affect the natural flow regime and which will not reduce the recharge capabilities." Paragraph 12 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 10, Objective III, "Natural Resources," of the LUE. Policy 10 states: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Paragraph 13 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 11, Objective III, "Natural Resources," of the LUE and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Respectively, these policies state: 11. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Paragraph 14 of the DCA Petition alleges that the development order is contrary to a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources," which describes the Green Swamp as a "rare and unique land area resource for conservation consideration" and also states: The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Paragraph 15 of the DCA Petition alleges that the development order is contrary to the following section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships": The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. Paragraph 16 of the DCA Petition alleges that the development order is contrary to Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan: "Protect or improve existing ground and surface-water quality." Paragraph 17 of the DCA Petition alleges that the development order is contrary to Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE: Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. Paragraph 19 1/ of the DCA Petition alleges that the development order is contrary to Policy 2, Objective IV, "Residential Uses," in Part V of the LUE: Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. Paragraph 20 of the DCA Petition alleges that the development order is contrary to Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code). 2/ Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Paragraph 21 of the DCA Petition alleges that the development order is contrary to Section 5-2(4) of Polk County Ordinance 81-28. 3/ Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Paragraph 22 of the DCA Petition alleges that the development order is contrary to Section 6-2(3)(a) of Polk County Ordinance 81-28. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site.
Findings Of Fact The Proposed Project and Location. The project site is on Dean Still Road in Polk County, approximately 2 miles west of State Road 33. It is approximately 6 and 1/2 miles from Polk City and 15 miles from the City of Lakeland. The proposed project is comprised of 356 lots on approximately 1280 acres with a gross density of 1 unit per 3.6 acres. Although the average lot size varies, the project was reviewed under the Southwest Florida Water Management District's (SWFWMD) criteria for rural development which requires that at least 90% of the lots be at least 2 acres in size (excluding jurisdictional wetlands), and 10% of the lots be at least 1 acre (excluding jurisdictional wetlands). The site has been zoned Rural Conservation under Polk County's Zoning Code for approximately 12 years. This designation allows a density up to 1 unit per acre. Individual water wells and on-site waste disposal systems (septic tanks) will be utilized for each home. There are no water or sewer extensions proposed for the site or for adjacent areas by any governmental entity. Access to the site from Polk City is along Dean Still Road, which is unpaved at this time. The County has plans to pave it in the near future. Of the 1280 acres comprising the project site, 362 acres have been claimed as jurisdictional wetlands and approximately 642 acres have been mapped within the 100-year floodplain by the Federal Emergency Management Agency (FEMA). 51 of the lots platted in the project are entirely within the FEMA 100- year flood plain. Several other lots contain large portions within FEMA 100- year flood plain. Despite the significant amount of wetlands and floodplains on the site, the project is designed so that no net loss will occur in the floodplains and less than 1% (.59%) of the jurisdictional wetlands will be impacted by development. Impervious conditions on the site will only increase by 2.8% after development. All structures will be set at or above the 100 year flood elevation, as calculated by the project engineers, and will be constructed in accordance with the County's flood protection standards. The project is designed so that post-development runoff is less than pre-development runoff and post-development drainage basins conform to pre-development drainage basins. Existing drainage patterns for the site are designed to be maintained. The property comprising the project has been used through the years for a variety agricultural purposes, including harvesting watermelons, soybeans, corn, and silage. It has been drained and ditched to facilitate these activities. It is currently being used for grazing cattle. A sod farm is located to the south of the property. Additional cattle grazing lands run south from there to Polk City. To the north of the site are ranchlands which run to the border of the Withlacoochee Wildlife Area. Immediately to the west of the site are 20-30 scattered mobile homes and additional ranchlands in a subdivision known as Evans Acres. This subdivision was initially approved by DCA in 1983, and was comprised of 48 lots on approximately 1,290 acres. The original lots ranged in size from 5 to 60 acres. Apparently, individuals have since split their lots and many of the existing lots are 2 to 5 acres in size. A few of the original lots are used for both residential and ranching purposes. Including the large and small lots, there are approximately 163 lots on the property comprising Evans Acres. On the property directly to the east of the site are approximately 16 mobile homes along Melody Lane. These existing homesite numbers are small and scattered when compared to the 356 lots proposed for Paradise Country Estates. Approximately 120 families live in the general vicinity of the proposed project. The Green Swamp. The project is within the Green Swamp Area of Critical State Concern (ACSC). The site is within the drainage basin of the Withlacoochee River, which has been designated an Outstanding Florida Water (OFW) and is approximately three and a half miles to the north. The Green Swamp ACSC was designated by the Legislature. Chapter 79- 73, 380.0551, Florida Statutes (1991). It was the second area to be designated and now is one of only four areas in the State retaining this designation. The Green Swamp was designated because the area's natural resources were considered to be of regional and statewide importance and because of concerns that uncoordinated development could endanger these resources. The Green Swamp is a regionally significant area for recharge of the Floridan Aquifer. The Green Swamp is unique because the top of the Floridan Aquifer is at or near the surface over much of the area. This creates what is known as the potentiometric high of the Floridan Aquifer. The potentiometric high pressurizes the Floridan Aquifer, permitting it to be used for drinking water wells. The Florida Aquifer serves as the principal source of drinking water for central Florida. It supplies the entire State with about 48 percent of its ground water supply. The potentiometric high also serves to hold back salt water intrusion into the Floridan. Recharge is important in maintaining the potentiometric high of the Floridan Aquifer. Although the Green Swamp has been characterized as a recharge area for the Floridan Aquifer, the actual recharge capabilities of the Green Swamp vary considerably throughout the region. Some areas within the Green Swamp, such as the high, dry, sandy ridge on the eastern boundary of the Green Swamp clearly are high recharge areas. In some areas, the Floridan Aquifer rises essentially to the ground surface, with no confining layer above it. In those areas, a considerable amount of surface water filters into the Floridan Aquifer. In other areas, including in the vicinity of the project site, recharge capability is considerably less. See "G. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code, (3) Ground Water Recharge." The head waters of several rivers, including the Withlacoochee River, are in the Green Swamp. Polk County's Comprehensive Plan. Polk County's Comprehensive Plan, as amended by Polk County Ordinance 85-08 (Ordinance 85-08), is referred to as Polk County's 1985 comprehensive plan, or the 1985 plan. It includes a Land Use Element (LUE) and a Conservation Element. The Land Use Element. The 1985 Plan is a "policy plan." As a "policy plan," the LUE does not map land use classifications or densities or intensities of development. The different parts of the plan must be considered together to ascertain their meaning. As stated in the Foreward to the LUE: The Policy Plan is a flexible and realistic guide to future public decisions. Existing conditions are first determined and analyzed. Then, community goals are identified providing a process of finding out where we are and where we want to go. * * * . . .. The challenge is to determine the means of achieving the identified community goals at minimal cost and the least possible hardship on any segment of our society. Under the policies planning process this is accomplished by developing all possible alternative courses of action that will advance the community toward the desire goal. The policies are then a general statement of purpose and outlining broad principles toward which the plan is guided in the implementation stage. A policy plan does not detail specific actions or locations on a map. Rather it provides a broad framework within which day-to-day decisions are made in a consistent manner toward an identified goal. The ultimate product of those community goals will be the heritage of Polk County's future. At 4-2, the LUE discusses the need to give attention to "the proper distribution of population densities in keeping with sound planning practices, the physical capabilities of the land, and the relationship of the population and housing densities to existing or proposed transportation facilities and other community services." It then speaks to "Retention of Open Spaces": A second potential problem to be faced, as urban growth continues, is the potential loss of the open space characteristics that now contribute substantially to its desirability as a community in which to live and visit. To a large extent, the desirable characteristics are provided by extensive agricultural areas. Such uses are compatible with residential and other types of urban land uses and should be encouraged to remain to the maximum extent possible. Desirable open space is also presently provided by . . . wetland areas not suited for urban development. By encouraging such areas to remain in their present condition, a substantial amount of open space can be retained to provide the needed visual relief and openness necessary within a highly urbanized community. At 4-5, discussing "Retention of Unique Agricultural Lands," the LUE states that cattle raising and field crops are subject to potential intrusion by urban development and states: "The development of planning techniques, which will encourage the retention of important agricultural lands and provide for orderly urban development, thus becomes a matter of considerable importance." The Goals, Objectives, and Policies (GOPs) of the LUE starting at 5-1 include the following: General Goal: To maintain productive and mutually compatible use of lands and waters within Polk County in a manner consistent with the economic, physical and social needs, capabilities, and desires of Polk County and its citizens. Objective I - Agricultural Uses: To ensure that a sufficient quantity of appropriate lands are available and protected for productive agricultural uses necessary to a sound economic base. Policies: * * * 2. Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. * * * 5. Provide all possible incentives for the retention of lands into agricultural production. * * * Objective III - Natural Resources Minimize adverse impacts of development on valuable natural resources including the protection of water quality and quantity in surface and ground waters. Policies: * * * 2. The subdivision and platting of land shall be permitted in accordance with the zoning district applied to the property and in compliance with the Polk County Subdivision Regulations and Flood Protection/Surface Water Management Ordinance. * * * Site alteration should be permitted only when such alteration will not adversely affect the natural flow regime or the natural recharge capabilities of the site. Site alteration should be permitted only when such alteration will not result in the siltation of wetlands or reduce the natural retention and filtering capabilities of wetlands. Site alteration activities should provide for water retention and settling facilities; should maintain an overall site runoff equivalent to the natural flow regime prior to alteration and should maintain a runoff rate which does not cause erosion. * * * Storm water runoff should be released into the wetlands in a manner approximating the natural flow regime. Structures should be placed in a manner which will not adversely affect the natural flow regime and which well not reduce the recharge capabilities. Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. Objective IV - Residential Areas To ensure that an adequate supply of appropriately located lands are available for the development and maintenance of residential areas that can be efficiently and effectively provided with necessary public facilities and services. Policies: Promote and encourage the provision of a wide range of housing opportunities, in appropriate locations, to permit a choice of housing types to suit the particular needs of all citizens. Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. * * * Encourage new residential development that can be effectively served by the existing transportation facilities. Promote new residential development in non-urban areas, that is properly designed to combine with future adjacent development, to create a neighborhood of sufficient size to facilitate the efficient and effective provision of all necessary public facilities and services. Part VI of the LUE, entitled "Alternate Approaches," discusses the pros and cons of different concepts for planning and managing of growth. It settles on a "Resource-Responsive Concept" as the preferred growth alternative. This concept holds in part: Wherever possible, future growth should be encouraged to take place in or near established urbanized areas. Scattered growth incapable of functioning as meaningful self-contained communities should be discouraged. And it is preferable that the urbanizing area, as it extends over extensive areas within the County, not be developed in one continuous, monotonous maze of residential, commercial, and industrial uses - but that there be open space provided at appropriate intervals so as to provide visual relief and a sense of scale to the overall urban community. Such open space areas can be productively utilized for agricultural and conservation purposes or recreation areas, public facilities and services required. It is proposed that the most appropriate urban growth concept to meet such guide-lines and the policy statements of this land use plan be a resource-responsive growth concept. Under this concept, urban growth and development will be guided and encouraged with respect to its responsiveness to the natural and human resource capabilities of the County. Within any given area of the County, the resources will be careful evaluated in terms of their capability to support growth, and the physical form and intensity of development will be then shaped to provide the physical form and intensity of development will be then shaped to provide a balance with such resources. Prime resources to be considered are as follows: Natural Resources Topography and soil conditions Vegetation and tree cover Wildlife habitats present Drainage characteristics; relationship to rivers and lakes Natural water supply capabilities General aesthetic qualities Human Resources Transportation facilities (roads, railroads, airports) Available water supply and sewage facilities Community facilities, such as schools, parks, libraries Protective services, such as fire and police Established land uses within the area Economic conditions and potentials. Part VII of the LUE, entitled "Implementation," states: "Initial implementation of a Comprehensive Plan and initiation of the continuing planning process for growth management requires the establishment of principals and standards for measurement of proposed activities against the adopted policies of the community." It includes a section entitled "Principles and Standards for the Control and Distribution of Population Densities and Structural/Development Intensity," which provides in part: All Types of Urban Development: * * * Each new development or land use should follow sound land planning principles to maximize site advantages, avoiding when possible, adverse impacts on the natural resources and hazards to health, safety, or general welfare. * * * Residential Development: Low-density single-family development (1-4 units/acre), other than rural residences related to agricultural operations, shall be located in areas capable of being developed into stable, cohesive neighborhoods. In a section entitled "Legal Requirements of Implementation," it states that "all actions taken by local government, whether in the form of permitting private development to occur or in the provision of public facilities and services, are required to be fully consistent with the adopted Comprehensive Plan. The plan, once adopted, must occupy a central position in the consideration of all proposed development." In another section, entitled "Coordination with Other Plan Elements," it states that the "land use element cannot be implemented alone [but] must be coordinated with the [other elements]." In another section, entitled "Needed Improvements in the Zoning Ordinance," it is recognized that "it will be essential that a thorough review of the zoning ordinance be undertaken and that the ordinance be revised as appropriate to achieve consistency with overall planning objectives." It acknowledges that there were "major identified deficiencies in the current zoning regulations" and advises that "the following needs among others should be addressed as a minimum in making revisions to the zoning ordinance": "Revision of the Density Requirement in Residential Districts." Despite the admonitions in the 1985 Plan, to date there has been no revision of the land use classifications, densities, or intensities in the County's zoning code. As before the 1985 Plan was adopted, zoning in the Green Swamp ACSC remains Rural Conservation (RC) and allows up to one unit per acre residential development. The Conservation Element. Part II of the Conservation Element of the Polk County Comprehensive Plan is a "Summary of Natural Resources." At 2-18, there appears a section entitled "Rare and Unique Natural Resources," which describes the Green Swamp, as well as other natural resources in the County, as a "rare and unique land area resource for conservation consideration." At 2-19, as amended by Ordinance 85-08, this element of the comprehensive plan also states: This area comprises the hydrologic heartland of Central Florida and contains the headwaters of the Withlacoochee, Hillsborough, Peace and Oklawaha Rivers. The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Part IV of the Conservation Element is a "Summary of Special Problems, Areas, Issues, and Relationships." Starting at 4-2, it addresses the following: Displacement . . .. Cities in Polk County have historically developed on the ridges and the urbanized areas are spreading outward rapidly into the prime citrus lands and the "marginal" (flood prone) lands. There is considerable concern about urban development in wetland soils and flood prone areas. The double barreled concern for development in wetland soils and wetland areas is that they might well serve valuable natural functions and the private and public problems created by development subjected to flood damages. This property damage promotes public pressure for drainage in wet areas. The issue in wetland drainage and flood control is the jeopardy of natural functions that wetlands and water fluctuations provide in natural systems and flood damage costs. . . . [C]oncern for the growing demand for uplands development which steadily displaces [good pasture land] . . . relate[s] to the use of good pasture land for development. Density The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. * * * Water * * * Another area of concern relates to the draw down and recha[r]ge of the Floridan Aquifer and is claimed to be a rational concern of an area much larger than Polk County. * * * Pollution Environmental pollution, as it relates to water, is a major local concern. * * * Water pollution is concerned because of its effects on recreation and tourism. Water degradation and the pollution of lakes and rivers tends to remove the intangible value that Polk County enjoys in thee form of its surface water resources. * * * Also, the related cost issues of municipal sewage treatment and disposal, effluent disposal techniques, septic tank useage are environmentally economic choices to be made by the public. Discussing the topic, "Preservation and Management," starting at 4-4, Part IV of the Conservation Element states in part: Many issues relate to what, how, or when something should be conserved. * * * Lakes, rivers and canals of the county are of concern as sources of flooding and as resources for flood control, if properly managed. Flood prone areas surrounding surface water have been identified for much of the county. These water bodies are also legitimate concerns as the habitat for fish and other wildlife that provide a significant value in their own right. The area of these water bodies are also special scenic and recreational values that contribute to tourism and development. Part V of the Conservation Element is where the "Goals, Objectives and Policies" are found. It start with some general observations, including in part: . . .. It can be expected, therefore, that the natural environment of the county will continue to undergo modification of one type or another in response to the needs of people. . . . The inventory of total space will, therefore, diminish as these changes take place, resulting in corresponding losses within particular categories of natural resources. What is important is that no critical loss of impairment of a natural resource take place; that development be managed so as to create minimum disturbance of the remaining natural resource systems; and that there be compensation replenishments of resources wherever possible. It then lists a General Goal and several resource-specific objectives and policies: General Goal: Maintain, protect, develop and utilized the natural resources in a manner that will balance and replenish the natural ecological systems and will best serve and promote the desired quality of life for Polk County resident, present and future. * * * Water Resource Objective: To conserve and protect the quality and quantity of water resources through proper management. * * * 6. Identify and protect significant acquifer [sic] recharge areas for maximum recharge capability and protect the water available for aquifer recharge. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Protect the functions of the Potentiometric High of the Floridan Aquifer. Prevent further salt-water intrusion into the Floridan Aquifer. Protect or improve existing ground and surface-water quality. Protect the water retention and biological-filtering capabilities of wetlands. Protect the natural flow regime of drainage basins. Rare and Unique Natural Resource Objective: To conserve and protect, through proper resources management, areas having unique natural characteristics and particularly sensitive environmental balance. * * * Policies: Identify all significant areas in Polk County deemed to have unique natural resource characteristics. Encourage proper management of unique wetland areas of the County as a vital water resource. Encourage a proper system for control of development in flood prone and wetland areas to regulate alternation [sic] of the natural system of water retention and storage during periods of heavy rainfall. Preserve and protect, to the maximum extent possible, all delineated areas having valuable unique resource characteristics. Part V of the Conservation Element concludes with a "Summary," which states in part: The objectives and policies set forth above should not be considered as controls to be rigidly applied in every instance of decision-making dealing with the natural environment. Rather, in dealing with resource conservation issues, guidance is preferable to control. . . . A number of potential implementation actions and programs, presented in the following part, will further assist in establishing the direction and scope of conservation activities in the County. Part VI of the Conservation Element is entitled "Implementation." While acknowledging at 6-1 that Polk County cannot establish an implementation program unilaterally, without regard to the co-responsibilities of other governmental authorities at the regional state and federal levels, it states at 6-2 that Polk County "can and should": Utilize the general objectives and policies established by this Element as considerations in all decision making concerning the use and improvement of land within the County. * * * 3. Utilize, to the fullest extent possible, the policies and implementation controls of other elements of the Polk County Comprehensive Plan, and those of other governmental entities having jurisdiction, to further the conservation of natural resources. Starting at 6-3, Part VI discusses the Conservation Element's "Relationship to Other Plans." At 6-4, after stating that the Conservation Element will be largely implemented through the policies and programs of other comprehensive plan elements, Part VI provides: Land Use Element - This element will provide the overall framework for conservation [sic] potentialities through the manner in which land uses are distributed, arranged, and interrelated throughout Polk County. Policies and implementation programs of this element will determine the degree to which new development is properly related to soil types and capabilities, natural habitats, flood prone areas, wetlands and unique resource areas of the County. Land regulatory controls such as zoning, subdivision regulations and development impact reviews provide the basic tools for implementation of the policies of the Land Use Element. Starting at 6-5, Part VI discusses "Guidelines for Implementation." At 6-5, it points out: The nature of conservation policy, being of such broad application and diversity of interest, requires that its effective implementation utilize many approaches, techniques and procedures. Its application is carried out, for the most part, in an indirect way as a by-product of other more direct decisions and actions relation to the development and growth of the County. It is essential, therefore, that Polk County draw upon all possible alternative mechanisms and techniques which will lead to the effective conservation of its natural resource systems. Among the various approaches which Polk County may utilize to further its conservation objectives are the following. * * * Influence in the allocation of resources to achieve the objectives of the conservation plan. Control of events which determine resources allocation in keeping with the conservation plan. * * * Specific procedures and techniques which may be utilized to facilitate the implementation process include the following. * * * 7. Protect natural water bodies and adjacent wetland areas through the regulation of development densities and proper management of stormwater runoff. This would require a cooperative effort with the Water Management Districts in identifying flood plains for various flood frequencies. Polk County's Flood Protection and Surface Water Management Code. Polk County's Flood Protection and Surface Water Management Code was enacted as Ordinance 81-28 and was amended by Ordinance 85-07. Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code. Land Use, Density and Intensity. DCA alleges that the land use, density and intensity of the development Crowder proposes for the site is inconsistent with: (1) the section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships"; (2) a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources"; (3) Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE; and (4) Policy 2, Objective IV, "Residential Uses," in Part V of the LUE. 6/ As previously stated, the 1985 Plan is a policy plan that does not map land use classifications or densities or intensities of development. Crowder's Paradise Country Estates is consistent with the County's Zoning Code, which has not changed since before the 1985 plan, and Zoning Map. The development was not otherwise reviewed for land use, density or intensity. But it is clear that the 1985 plan does not condone exclusive resort to the zoning code to determine the appropriateness of the land use, density and intensity for development in the Green Swamp ACSC. See, especially, the section entitled "Density" in Part IV of the Conservation Element of the Plan. In the Green Swamp ACSC, especially, reference must also be made to the Plan itself. See Part VII of the LUE, entitled "Implementation." It is not found that all residential use on the Crowder property would be, in itself, inconsistent with the 1985 Plan. But, taking into consideration all of its land use, density and intensity provisions, it must be found that the development order issued in this case, especially at its level of density and intensity and especially in the manner of its issuance, is inconsistent with the 1985 Plan. The crux of the problem with this development, like others in the Green Swamp ACSC already permitted by County development orders, is that, first, the 1985 comprehensive plan and the County zoning regulations in place at the time were inadequate and, second, the steps envisioned in the plan to make them adequate have not been taken. For the plan and the zoning regulations to be adequate, and for a development order for a project in the Green Swamp ACSC in Polk County to be consistent with the 1985 comprehensive plan, either: (1) the plan must be amended to map land use classifications, densities and intensities of development in the Green Swamp ACSC; (2) the zoning code must be amended as envisioned in the comprehensive plan for the Green Swamp ACSC; or (3) the County must evaluate development orders for projects in the Green Swamp ACSC on a case- by-case basis for consistency with the comprehensive plan. None of these three possibilities happened in this case. 7/ Flood Plain Delineation. Paragraph 12 of the DCA Petition alleges that the Crowder development violates Policy 10 of Objective III, "Natural Resources," of the LUE: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Specifically, it is alleged that the use of a Federal Emergency Management Agency (FEMA) undetailed "A" zone to map the flood prone area on the site, and the failure to perform a detailed study, did not comply with the Flood Disaster Protection Act of 1973. Other allegations in the DCA Petition also implicate the delineation of the flood prone areas on the site. See, (5) Ground and Surface Water Quality, below. A FEMA "A" zone is the zone depicting the area determined by FEMA to be flood prone. In this context, FEMA defines a "flood prone" area as an area flooded in a 100-year, 24-hour storm. At the time Polk County reviewed the Crowder project for approval of the roadway and construction drainage plans, FEMA was requiring that a detailed study be performed to delineate the flood prone area. Polk County apparently was not aware of this requirement and was not enforcing it. Nor, apparently, was Crowder's engineer aware of it. In any event, Crowder did not have a detailed study performed to delineate the flood prone area on the site, and the County did not require it. In approximately March, 1992, Polk County received a written communication from FEMA advising of the requirement for a detailed study of the flood prone area in the case of developments like Crowder's. Polk County now requires compliance with this FEMA requirement. Crowder did not rely simply on the FEMA undetailed "A" zone to map the flood prone area on the site. Crowder's engineers used the existing undetailed FEMA maps as a starting point for determining base flood elevations. The engineers digitized the areas which had been designated as flood prone on the FEMA panels. The engineer then overlayed the digitized FEMA map with the on- site wetlands survey of the property, which had been field-staked and field- shot. Topographical field shots of the property which had been conducted throughout the site at one foot intervals were also overlayed on the digitized FEMA map. In addition, the engineer took into consideration mapped wetlands soils and compared flooding conditions which had occurred on adjacent property to assess whether all areas actually prone to flooding had been characterized as flood prone on the FEMA map. The methodology used by the project engineers was based on sound engineering practices. Nonetheless, it does not qualify as a "detailed study" as far as FEMA is concerned. A "detailed study" would include the application of a computer program that would "route" hypothetical flood waters onto and through the property to ascertain flood elevations in different stages of the hypothetical flood. It is not possible to determine how a detailed study would change the delineation of the flood prone area in Crowder's proposal. The total area of flood prone area could either increase or decrease; it could increase in some places and decrease in others. As it is, several of the lots platted in the Crowder development would be entirely within both the FEMA undetailed "A" zone and the flood prone area mapped by Crowder's engineers. Ground Water Recharge. DCA alleges that platting Paradise Country Estates will adversely impact recharge of the Floridan Aquifer, contrary to Policy 9 and 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. In the vicinity of the project site, the Floridan Aquifer comes to within 35 feet approximately of the ground surface. Above the Floridan Aquifer is a shallow aquifer, which rises to within approximately 12 inches of the surface. There is a layer of clastic soils (sand and clay) between the surficial aquifer and the Floridan Aquifer. This confining layer slows the rate of recharge to the Floridan. As a result, the project site is in an area having low, or even very low, to moderate recharge capabilities, at best. USGS Professional Paper 1403-E, which was released in 1990, uses groundwater modelling to quantify recharge rates, instead of using qualitative terms such as "low," or "poor," "moderate" and "high" to describe recharge capabilities. USGS Professional paper 1403-E reports that many areas in the Green Swamp previously labeled as good, moderate or high recharge areas are actually capable of only recharging at rates of 3 to 4 inches per year. The subject property appears to be in the 2 to 3 inch range per year for recharge according to USGS Professional Paper 1403-E. Only three known sample soil borings have been taken on the project site. As a result, the extent of permeability and overall thickness of the confining layer between the surficial and Floridan aquifers is not certain. But there is no reason to believe that there are any karst features or other geologic faults in the area that would allow for direct connections between the surficial and Floridan aquifers. The soil borings that have been taken on the site verify the various geological surveys and studies describing the recharge capabilities in the area. Due to the site's limited capabilities as a recharge area, it is unlikely that the platting of this site will result in any significant reduction in its natural recharge rate. The project is not inconsistent with Policy 9 or 11, Objective III, "Natural Resources," of the LUE, or Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Individual Water Well Use. DCA alleges that the planned use of individual water wells in Crowder's Paradise Country Estates will impact the quantity of the Floridan Aquifer (and the surficial aquifer) contrary to Policy 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. The potentiometric level of the Floridan Aquifer protects the Floridan Aquifer from salt-water intrusion. Significant de-watering of the aquifer caused by large municipal or industrial wells extracting a high volume of water from the aquifer at an intense rate can lower the potentiometric pressure, thus increasing the potential for salt-water intrusion into the aquifer. (Furthermore, the lowered potentiometric pressure creates a hydraulic gradient which encourages surface waters to percolate downward at a faster rate due to the decreased pressure in the Floridan Aquifer. See the preceding sections on Ground Water Recharge and the following section on Ground and Surface Water Quality.) Large municipal, industrial or agricultural wells which exceed 6 inches in diameter must obtain consumptive use permits from the SWFWMD. The Water Management District takes into account what the District determines to be a safe yield per acre when issuing a consumptive use permit. Small, residential wells are not subject to this permitting process as their impacts are much smaller and less intense, and not a concern with regard to their effect on the potentiometric pressure. For this reason, some coastal areas have begun using smaller, individual wells as an alternative to larger municipal wells. The Floridan Aquifer is replenishing itself fast enough for residential wells not to "de-water" or "draw down" the aquifer's supply of ground water. Residential wells do not lower the potentiometric pressure of the Floridan to a significant degree. Nor would they affect the normal supply of ground water, or contribute to salt-water intrusion. Pumping tests performed within two to three miles west of the project site which utilized several residential-size wells support the foregoing conclusions. For these reasons, it is found that the development will not adversely impact the normal supply of ground water and thus will not interfere with the functions of the potentiometric high of the Floridan Aquifer, including its protection against salt-water intrusion. Since the water wells would pump only from the Floridan Aquifer, they would not impact the supply of surface water. In regard to the use of water wells, the project is not inconsistent with Policy 11, Objective III, "Natural Resources," of the LUE, or with Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Ground and Surface Water Quality. DCA alleges that Paradise Country Estates will result in unacceptable contamination of the Floridan Aquifer, the surficial aquifer, and the surface water (particularly the Withlacoochee River) contrary to Policies 9, 10 and 14 of the "Water Resource Objective" of the Conservation Element. Paragraph 20 of the DCA Petition alleges that the use of individual on-site disposal systems (OSDS), or septic tank systems, in violation of Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code), 8/ in particular, will be part of the cause of the unacceptable contamination (other causes being from lawn and garden maintenance and automotive wastes.) On-Site Disposal Systems. Chapter 10D-6, Florida Administrative Code, sets forth requirements for the use of on-site waste disposal, or septic tank, systems in the State of Florida. That chapter, which is administered by the Department of Health and Rehabilitative Services ("HRS") through local health departments, provides construction standards for the installation of on-site waste disposal systems. The septic tank serves as a holding tank designed to separate solids and floatable materials and allows anaerobic digestion of organic materials. The remaining effluent exits the tank into the soil infiltrative process, which is referred to as the drainfield. The drainfield is composed of gravel placed around perforated pipes, which are designed to evenly distribute and release the effluent into soil material where the effluent undergoes aerobic digestion. Eventually, any constituents remaining in the effluent which have not been absorbed by the root zone or otherwise decomposed reach the subsurface waters which are referred to as the surficial water table. Each individual lot owner will be required to obtain a permit from the local health department prior to installing an on-site waste disposal system. Prior to issuing a permit, HRS inspects each site to assess soil limitations and to conduct a percolation test to determine the seasonal high water table for the site. Because the soils on the site are severely limited for filtration purposes and the high water table is only 10 to 12 inches below the surface, individual lot owners will be required to mound their on-site waste disposal systems to overcome these limitations. Although the fill used to mound the systems will be comprised of suitable soils, it is possible that the foreign soils will absorb moisture from the existing soils on this site, a phenomenon referred to as capillary fringe affect. This phenomenon can cause those portions of the fill which come in direct contact with the existing soils on the site to lose their filtration capabilities. Unless the fill becomes saturated from other sources, it is unlikely that capillary fringe affect will render the filtration process ineffective. The effects of capillary fringe affect can be lessened by mixing fill with soils found on the site, a practice undertaken by contractors when installing on-site waste disposal systems. In addition, increasing the amount of fill used to mound the system would decrease the potential affects of this phenomenon. 9/ Floridan Aquifer Water Quality. In some areas of the Green Swamp, the Floridan Aquifer is actually considered a surficial aquifer since no confining layers of soil or clay separate the subsurface water from the Floridan Aquifer. These areas would typically be characterized as areas with high recharge capabilities (or high potential for contamination). However, throughout the project site, a confining layer exists which is composed of clayey sands which have a very low permeability. Therefore, there is relatively little interaction between the surficial aquifer and the Floridan Aquifer on this particular site. For this reason, the use of individual on-site waste disposal systems on this site would pose no significant risk to the water quality of the Floridan Aquifer. Surficial Aquifer and Surface Water Quality.-- As for the surficial aquifer and surface water quality, Chapter 10D-6, Florida Administrative Code, requires on-site waste disposal systems be located at least 75 feet from waterbodies. Normally, and when the systems are operating properly, this assures that adequate filtration and decomposition occurs before wastewater reaches surface waters on or near the site. But, in the case of the Crowder proposal, it is necessary to consider that at least some of the mounded systems will be subjected to flooding and will become saturated. Even based on the analysis by Crowder's engineers, 51 of the lots in Paradise Country Estates are entirely flood prone; there is no place to put an OSDS on those lots that is not flood prone. If a "detailed study" had been done, it is possible that more lots would be entirely within the flood hazard zone. Other lots not entirely within the flood zone may not be able to accommodate an OSDS on the part of the lot not within the flood zone. If the OSDS mound is saturated during flood conditions, the system will fail, and untreated waste, or inadequately treated waste, will be released into the surface flood waters. This waste water will move laterally across the project site. Roots may absorb some nitrates or other organic compounds; 10/ otherwise, the waste water and its constituents will remain in the surface water. Lateral movement across the site generally will be slow, as the site is relatively flat. Some of the waste water and its constituents will get into the surficial aquifer. There are ditches or canals alongside and on the site that will direct the rest of the surface water into Pony Creek and other tributories of the Withlacoochee River, an Outstanding Florida Water approximately three and a half miles to the north. The Department of Environmental Regulation issued a dredge and fill permit for the project's road network's impact on wetlands on the site. But it did not pass on the use of OSDS in the individual lots. It also erroneously referred to the Withlacoochee as a natural Class III, instead of an Outstanding Florida Water. See F.A.C. Rule 17-302.700(9)(i). The Southwest Florida Water Management District (SWFWMD) issued a surface water management permit for the project. In evaluating a permit application, SWFWMD considers surface water quality. But the focus of SWFWMD's inquiry is the pre- and post-development peak flows. Also, when it considers water quality, SWFWMD considers the impact of site alteration on water quality, not the impact of the use of OSDS on the site. In addition, the Crowder project was reviewed under special criteria for low-density rural subdivisions that do not require the submission of as much information. It was not clear from the evidence precisely how SWFMD evaluates water quality under those criteria. For these reasons, based on the evidence, it cannot be said that the Crowder project's OSDS will be meet the minimum standard of being "located to avoid impairment to them or contamination from them during flooding," as required by Section 5-1(6) of Polk County Flood Protection and Surface Water Management Code, or that the project will "protect the normal . . . quality of ground and surface water . . . necessary for the protection of resources of state and regional concern," as required by Policy 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Finally, the project will not "protect or improve existing ground and surface-water quality," as required by Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan. Other Appeal Issues. Except as set forth above, the Crowder development did not violate the 1985 comprehensive plan and Flood Protection and Surface Water Management Code provisions cited in the DCA Petition. Agency Practice - Other Development in the Area. As previously described, Evans Acres, to the west of the Crowder site, was approved by DCA in 1983. (See Finding 10, above.) As approved, it was comprised of 48 lots on approximately 1,290 acres (a density of one unit per 27 acres). The original lots ranged in size from 5 to 60 acres. Unbeknownst to the DCA, individuals apparently have since split their lots and many of the existing lots are 2 to 5 acres in size. A proposed development known as Turkey Creek is located between the project site and Evans Acres. Turkey Creek is comprised of approximately 57 lots on 170 acres with a gross density of 1 unit per 3 acres. The physical characteristics of the Turkey Creek property, including the abundance of wetlands and floodplains, are essentially the same as the proposed project site. DCA appealed Turkey Creek in June of 1992. However, in that case, the County had been approximately two years late in rendering the Turkey Creek development order to the DCA. Meanwhile, the developer incurred development expenses and already had constructed roads and drainage facilities for the development. The developer, the County and DCA executed a settlement agreement which allows the development to proceed according to the original construction plans, but requires homeowners to install dual septic tank systems and have their septic tanks cleaned and inspected every three years. Several other developments, which are in the general vicinity of the project site and have many of the same physical characteristics, including Yearling Trace and Buck Hill, have been appealed by DCA. Yearling Trace is comprised of 108 units on approximately 544 acres. Buck Hill is comprised of 55 units on approximately 214 acres. Those projects were appealed by DCA in June and April, 1992. In some of these cases, the County did not timely render development orders to DCA in a timely manner. In the case of Buck Hill, the DCA had been mailed an unapproved copy of development plans in October, 1990; in early 1992, DCA contacted the County to inquire, as no County-approved development plans ever had been sent to the DCA. In many of these cases, substantial development expenses had been incurred; in some cases, roads and drainage facilities already had been constructed. DCA decided to settle the pending appeals in which the County was late rendering the development order, and in which the developer already had constructed roads and drainage facilities, consistent with the Turkey Creek settlement. In cases where the County was late rendering the development order, but the developer had not already constructed roads and drainage facilities, the DCA determined to settle not only for stipulations to upgrade the OSDS, as in the Turkey Creek settlement, but also for requirements that a "detailed" flood zone study be done, in accordance with the FEMA requirements. Prior to the DCA appeal, Crowder had expended approximately $31,000 in permit fees. In addition, he has incurred development costs, primarily for engineering fees and related services. Through the time of the final hearing, he had spent approximately $99,000 on engineering fees and services. (The evidence was not clear how much had been incurred by the time of the DCA appeal.) However, the County was not late in rendering the Crowder development order, and Crowder has not constructed roads or drainage facilities. In view of the different circumstances in Crowder's case, DCA's prior agency practices do not compel that Crowder's development be treated in the same manner, i.e., be settled on the same terms, as the Turkey Creek and the others. DCA has argued that FLWAC's Final Order in the case of Dept. of Community Affairs v. Narbi International Company, Inc. and Lake County, 14 FALR 3223 (1992), controls this case and requires the Crowder development order to be overturned on appeal. Narbi involved development Green Swamp ACSC, albeit in Lake County. Factually, there are many differences between Narbi and this case. The Narbi development order was a rezoning from agricultural with a residential density of up to one unit per five acres to a residential planned unit development (PUD) zoning with a density of one unit per 1.35 acres. Also, Lake County's comprehensive plan had an "urban containment policy," which DCA equated with its non-rule policy preventing "urban sprawl" or "leap-frog development." Thirdly, in Narbi, it was found that a geologic fault existed on the project site which allowed a direct connection from the surficial aquifer to the Floridan Aquifer. Because of the factual differences, Narbi does not control the outcome of Crowder's case. Conditions for Approval. Based on the testimony of its witnesses, DCA has proposed that, notwithstanding its deficiencies, the Crowder project can be approved if its density is lowered to between one unit per ten acres and one unit per 20 acres. The rationale of DCA's witnesses seems to be that the proposed lower density, in and of itself, would cure at least the most significant of the deficiencies. Since the Crowder development order under review was for approval of particular road and drainage plans, the plans would have to be redrawn at the lower density and resubmitted for approval by the County subject to the final order to be entered in this case. It is not possible for the Commission to approve, on condition of lowered density, the plans that were the subject of the development order in this case.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Florida Land and Water Adjudicatory Commission enter a final order rescinding and denying approval for the development order in this case. RECOMMENDED this 10th day of March, 1993, in Tallahassee, Florida. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 10th day of March, 1993.
The Issue The issue is whether the plan amendment adopted by Ordinance No. 2004-026 on August 24, 2004, is in compliance.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background The County's original Plan was adopted on August 31, 1989, and became effective on September 11, 1989. In 2000, the County amended its Plan by establishing a Managed Growth Tier System, which includes five classifications of land (Urban/ Suburban, Exurban, Rural, Agricultural Reserve, and Glades), along with three classes of service areas within the County to guide delivery of public services: Urban Area, Limited Urban Service Area, and Rural Service Area (RSA). It also assigned different levels of service for potable water and wastewater for each service area. At the same time, the County amended its FLUE to add a new Policy 3.4-c, which provides as follows: The County shall neither provide nor subsidize the provision of centralized potable water or sanitary sewer in the Rural Service Area, unless urban levels of service are required to correct an existing problem, prevent a projected public health hazard or prevent significant environmental degradation, or the areas meet the criteria described in Future Land Use Policy 3.4.b. The County intended Policy 3.4-c to implement the Managed Growth Tier System by limiting the provision of centralized utility service in the Rural Tier. The effect of this new policy was to prohibit the County from providing urban levels of utility services outside its existing service area boundaries in the RSA unless necessary to correct or prevent a public health hazard, existing problem related to urban levels of service, or environmental degradation. In February or March 2003, the County Planning Department began assessing ways to address the problem of overlapping utility service in the RSA. Shortly thereafter, the Florida Legislature passed the Scripps Law (Chapter 2003- 420, Laws of Florida), which took effect on November 3, 2003. Both of these factors led to the development of the Amendments in issue here. In late 2003, the County staff began the actual development of new amendments to its Plan (also known as Round 04-1 Plan Amendments) that would allow the County to provide services into the RSA. More specifically, the staff proposed to add a new FLUE Policy 3.1, which (as finally drafted) read as follows: The Palm Beach County Water Utilities Department shall provide potable water, reclaimed water and wastewater service to all unincorporated areas of the County except those unincorporated areas where the Palm Beach County Board of County Commissioners has entered or enters into a written agreement that provides utility service area rights to a public or privately owned potable water, reclaimed water, and/or wastewater utility, or in areas where the Palm Beach County Water Utilities Department is specifically excluded from providing utility service by Florida law. Palm Beach County Water Utilities Department shall continue to provide utility services to incorporated areas where service is already being provided by the County, or as provided for under utility service area agreements or as allowed for by law. In general terms, the new policy designated the County as a service provider of water and wastewater services for unincorporated areas of the County where the County has, or will enter into, interlocal agreements except where excluded by interlocal agreement or by law. The effect of the amendment is to allow the County to extend potable water and wastewater services to unincorporated areas of the County, particularly "the western communities," where it currently does not do so. The County staff also proposed to delete FLUE Policy 3.4-c, described in Finding of Fact 1, which was previously adopted in 2000. Finally, the County staff proposed to delete another policy adopted in 2000, CAI Policy 1.5-c, which read as follows: Urban levels of service shall not be provided by any governmental entity (outside of its existing service area boundary) within the Rural Service Area of the unincorporated area, except where: The Rural Service Area receives urban services pursuant to Objective 1.1 in the Element, or An urban level of service is required to correct a demonstrated public health, or Development on a parcel in the Rural Tier that is adjacent to water and/or sewer lines which existed prior to the adoption of the Comprehensive Plan in 1989 shall be allowed to connect to those existing lines and shall be allowed to connect to public sewer and/or water when required by the Public Health Department. This policy shall not allow the extension of new water and/or sewer lines into the Rural Tier to serve development without first amending the Service Area Map and the Future Land Use Atlas to reflect a change in the service area boundary. By deleting these two provisions, the County would no longer be prevented from providing utility services in the RSA unless certain conditions were met. (The staff also proposed to delete FLUE Policy 1.4-k, but that deletion is not in issue in these proceedings.) On January 14, 2004, the County initiated the adoption process by transmitting Notice of the Amendments to the Intergovernmental Plan and Amendment Review Committee (IPARC), which is made up of all the local governments and special districts in the County, including the City, Wellington, SID, and ITID. IPARC acts as a clearinghouse for all comprehensive plan amendments prepared by the IPARC members. IPARC in turn distributed the notice to its members, including the City, Wellington, SID, and ITID. After a public hearing on March 12, 2004, before the County's Local Planning Agency (known as the Land Use Advisory Board), by an 11-0 vote it recommended denial of Round 04-1 Plan Amendments and recommended that the County meet with the affected parties to resolve problems voiced by various attendees, including the City, SID, and ITID. On April 2, 2004, the County held a meeting with interested persons in an attempt to resolve objections to the Amendments before they were presented to the Board of County Commissioners. The objections were not resolved. On April 5, 2004, by a 5-0 vote, the Board of County Commissioners approved transmittal of the Amendments to the Department, other commenting agencies, and each unit of local government or governmental agency that had filed a written request for copies of the Amendments. The Amendments were transmitted to the Department on April 15, 2004. Between January 2004 and August 2004, the County held at least 37 meetings with utilities and other interested persons to discuss the Amendments, including three meetings with the City, at least five meetings with SID, at least ten meetings with ITID, and at least two meetings with Wellington. In addition, the County invited all utilities to attend meetings on April 28, 2004, at three locations to discuss utility service area boundaries. These meetings were attended by approximately 25 different utilities, including the City, SID, ITID, and Wellington. As a result of these meetings, the County prepared and distributed utility service area maps in an attempt to demonstrate the necessity for better coordination between utilities. On May 21, 2004, the Treasure Coast Regional Planning Council notified the County of no objection or comments regarding the Amendments. On June 19, 2004, the Department issued its Objections, Recommendations, and Comments Report, which did not identify any objections, recommendations, or comments with respect to the Amendments. On June 22, 2004, the South Florida Water Management District (District) notified the Department of no objections or comments regarding the Amendments. After a public meeting on August 24, 2004, by a 5-1 vote, the Board of County Commissioners adopted Ordinance No. 2004-26 enacting the Amendments, and they were transmitted to the Department on September 14, 2004. On October 29, 2004, the Department issued its Notice determining the Amendments were in compliance. On November 19, 2004, Petitioners (except Wellington) filed Petitions challenging the Amendments. Wellington filed its Amended Petition on December 16, 2004. The Parties and Their Standing The City is a municipality and adjoining local government of the County, operating its own water and wastewater utility system. The City owns the largest water treatment plant in the County and has an extensive wastewater treatment system, including partial ownership in the East Central Regional Water Reclamation Facilty, the largest wastewater plant in the County. It owns property and currently provides bulk service to entities located within the unincorporated area of the County, including ITID. It submitted written objections to the County during the adoption process and has standing to bring this action. SID is an independent special district created by special act of the legislature in 1970. It lies within the unincorporated area of the County and has the authority to provide water and wastewater service within and without its boundaries. At present, SID provides potable water service within and without its boundaries, but only provides wastewater service within its boundaries. SID owns property in the unincorporated area and submitted objections to the County during the adoption process. These facts establish that SID has standing as an affected person to challenge the Amendments. Callery-Judge is a limited partnership, which owns and operates citrus groves on property located within the unincorporated area. It also submitted objections to the County during the adoption process. Callery-Judge is an affected person and has standing to participate in this matter. Mr. Roberts owns property in the unincorporated area, including Callery-Judge, of which he is the General Manager. He submitted objections to the Amendments during the adoption process and is an affected person. ITID is an independent special district created by special act of the legislature in 1957. (In 2002, the Legislature amended and reenacted ITID's enabling legislation.) In 1998, ITID began operating a water and wastewater system within the unincorporated area. ITID does not generate its own potable water or treat its wastewater. It obtains bulk water from the City and SID and bulk wastewater service from the City. ITID owns property within the unincorporated area and submitted objections to the amendment during the adoption process. As such, it is an affected person within the meaning of the law. Wellington is a municipality and adjoining local government of the County and operates a utility providing water and wastewater service within its boundaries and outside to several developments. It also submitted objections to the County during the adoption of the Amendments. Because Wellington does not own property or operate a business within the unincorporated area of the County, in order to demonstrate standing, it must show that the Amendments will produce substantial impacts on the increased need for publicly funded infrastructure or substantial impacts on areas designated for protection or special treatment within its jurisdiction. See § 163.3184(1)(a), Fla. Stat. Wellington bases its standing on alleged increases in traffic and the use of parks within its boundaries, which purportedly will occur as a result of the Amendments. While Wellington could not give a precise amount (in terms of dollars) of those impacts, the testimony of its Director of Community Services established that the availability of centralized water and sewer services in the areas adjoining Wellington will arguably lead to higher density development patterns, which in turn will lead to an increased need for publicly funded infrastructure. As such, Wellington is an affected person and has standing to challenge the Amendments. The Department is the state planning agency charged with responsibility for reviewing and approving comprehensive plans and amendments. The County is a political subdivision of the State of Florida and is responsible for adopting a comprehensive plan and amendments thereto, including the Amendments. The County Water Utilities Department currently serves approximately 425,000 people, making it the largest utility provider in Palm Beach County and the third largest in the State of Florida. The Current Plan As noted above, the County initially adopted its current Plan on August 31, 1989, by Ordinance No. 89-17. The Plan has been amended numerous times since its initial adoption. The original 1989 Plan and all subsequent amendments up to the ones at issue in this proceeding have been found in compliance by the Department. The current Plan is made up of sixteen elements, nine of which are mandatory, and seven of which are optional. The parties have indicated that the Utilities Element, CIE, Intergovernmental Coordination Element, and FLUE are relevant to this controversy; therefore, a brief description of their content and purpose is necessary. The purpose of a Utilities Element is to provide necessary public facilities and services correlated to future land uses. See § 163.3177(6)(c), Fla. Stat., and Fla. Admin. Code R. 9J-5.011. The existing Utilities Element contains potable water, wastewater, drainage, and solid waste sub- elements. The aquifer recharge sub-element is found in the Coastal Management Element. The Utilities Element and the aquifer recharge sub-element of the Coastal Management Element constitute the "general sanitary sewer, solid waste, drainage, potable water, and natural groundwater aquifer recharge element" referenced in Section 163.3177(6)(c), Florida Statutes, and Florida Administrative Code Rule 9J-5.011. The existing Utilities Element has been found in compliance with applicable provisions of statute and rule. Section 163.3177(3)(c), Florida Statutes, and Florida Administrative Code Rule 9J-5.016 contain requirements for the capital improvements element of a comprehensive plan. The existing CIE complies with these requirements. Objective 1.7 and Policy 1.7-a describe how the County implements the CIE. Pursuant to these requirements, the CIE is updated annually at the same time as the County budget. Table 10 of the CIE reflects the water utilities revenue and expenditures for the then current budget year and five years into the future. Table 10 was not updated when the Amendments were adopted because any future changes to the County's capital expenditures resulting from the Amendments would be made through the annual budget update process. The Intergovernmental Coordination Element contains provisions encouraging coordination between the County and adjoining municipalities and special districts in order to more efficiently meet the needs of the County residents. (There are more than 25 municipalities and special districts within the County.) This Element has previously been found in compliance with Section 163.3177(6)(h), Florida Statutes, and Florida Administrative Code Rule 9J-5.015. One of the coordination tools identified in the Intergovernmental Coordination Element is the IPARC, described in Finding of Fact 5, which acts as a clearinghouse for all comprehensive plan amendments prepared by the IPARC members. IPARC distributes notice of plan amendments to all members, who then have the opportunity to provide comments regarding the proposed action. Section 163.3177(6)(a), Florida Statutes, and Florida Administrative Code Rule 9J-5.006 contain requirements for the future land use element of a comprehensive plan, including the future land use map (FLUM). According to the Plan, the FLUE "is the nucleus of the . . . Plan" and "defines the components of the community and the interrelationship among them, integrating the complex relationships between land use and all of the other elements of the Plan that address the physical, social, and economic needs of the people who live, work, and visit Palm Beach County." Both the existing FLUE and the current FLUM have been found in compliance. The Amendments do not alter the FLUM, but they do change FLUE Policy 3.1-c and delete FLUE Policy 3.4-c. As noted above, in 2000 the County adopted a Managed Growth Tier System, which is a planning tool intended to manage growth and protect varying lifestyles in the County. The Managed Growth Tier System consists of five categories or tiers, which are described in Objective 1.1 of the Plan. Objectives 1.2 through 1.6 govern development within the five tiers. FLUE Table 2.1-1 establishes permitted densities for each of the tiers. The Amendments do not modify any Goals, Objectives, or Policies governing the five tiers, with the exception of FLUE Policy 1.4-k. However, Petitioners have not challenged the proposed deletion of FLUE Policy 1.4-k and it is not one of the Amendments at issue in this proceeding. Additionally, the Amendments will not alter the permitted densities for any of the tiers. Concurrency Management refers to the system adopted in the CIE to ensure that infrastructure, which meets or exceeds the established minimum level of service standards, is in place concurrent with development approval. According to FLUE Policy 3.5-a, development orders and permits shall not be approved unless services and facilities meet or exceed the minimum levels of service. FLUE Objective 3.1 establishes three graduated service areas in Palm Beach County -- the Urban, Limited Urban Service, and Rural Service Areas. Each service area corresponds to one or more of the five tiers. The minimum levels of service required for each area are listed in FLUE Table 3.1-1. According to FLUE Table 3.1-1, FLUE Policy 3.5-a, and Utilities Element Policies 1.2-g and 1.3-e, the minimum levels of service in the RSA for potable water and sewage are on-site wells and septic tanks, respectively. With the exception of water and sewer, the other minimum levels of service are the same for all three service areas. The Amendments do not alter the minimum levels of service for any service area. Through its planning expert, Wellington contended that the Amendments will cause a de facto change to the minimum levels of service. However, the extension of centralized water and sewer service into the RSA does not change the established minimum levels of service. Petitioners also argue that the Amendments will increase minimum levels of service in the RSA for traffic and parks. However, the minimum levels established in FLUE Table 3.1-1 for all services and facilities, other than potable water and sanitary service, are County-wide standards. Reasons for Adopting the Plan Amendments Policy 3.4-c did not have its intended effect because it prevented the County from providing service to the Rural Tier. After 2000, repeated efforts by the County to negotiate the service areas of the numerous entities operating utility services in the unincorporated area were unsuccessful. Indeed, "there was not a willingness of many utility providers to agree on anything." This created a lack of coordination and planning as to the provision of services in the Rural Tier. The City, SID, and ITID each have utility service areas which overlap the service area of other utility providers. In particular, portions of the Acreage, a community located in the central-western unincorporated area of the County, fall under the claimed utility jurisdiction of SID, ITID, Cypress Grove Community Development District, and the Village of Royal Palm Beach (Royal Palm Beach). The City is also rapidly expanding service in the unincorporated area by entering into bulk water service agreements with a number of utilities located in the Rural Tier, including Royal Palm Beach, Seacoast Utilities Authority, and ITID. The City intends further expansion of bulk service in the Rural Tier, so as to increase utility revenues. It views the Amendments as affecting its substantial interests by potentially limiting these revenues. Royal Palm Beach claims an exclusive utility service area which overlaps the utility service areas claimed by SID and ITID. Royal Palm Beach is located entirely within the legislative boundaries of ITID and claims all of ITID as its service area. The Amendments support the authority granted to the County by the Scripps Law. That law gives the County the exclusive right to provide water and wastewater service to the Scripps Biomedical Research Facility and to construct utility facilities within and without the boundaries of the Scripps project. The enactment of the Scripps Law reinforced the need for the Amendments, as the Scripps Biomedical Research Facility will be located in the unincorporated area. Existing FLUE Policy 3.4-c is arguably inconsistent with the Scripps Law because it prevents the County from providing utility service in the RSA. Since the Scripps Law supersedes all other contrary provisions of Florida Law, it logically follows that FLUE Policy 3.4-c should be repealed. The Amendments are also supported by the provisions of the County Code of Ordinances Sections 27-16 through 27-22, which codify County ordinances that were adopted in the 1970s and deal with utility service. These ordinances authorize the County to designate a Control Area in the unincorporated area and to require County approval of any water and wastewater facilities constructed in these areas. In summary, the County adopted the Amendments to avoid service area disputes between utility providers such as those described above, to prevent wasteful and duplicative utility services, to implement the Legislature’s mandate regarding the Scripps Biotechnology Park, to ensure a sufficient water supply to meet the reasonable development needs of the unincorporated area, and to enforce the provisions of the County Code of Ordinances. Petitioners' Objections Data and analysis Petitioners contend that the only data and analyses submitted by the County to support the Amendments are contained in a rather brief County Staff Report (Petitioners' Exhibit 5), and that no other documentation was actually forwarded to the Department. They further contend that the Amendments must be based on demographic, economic, and fiscal studies, and that none were utilized by the County. Because of these omissions, they argue that the Amendments violate relevant statute and rule provisions and are not in compliance. Section 163.3177(8) and (10)(e), Florida Statutes, and Florida Administrative Code Rule 9J-5.005(2) require that plan amendments be based on relevant and appropriate data and analyses applicable to each element. In determining whether a plan amendment complies with this requirement, the Department reviews each amendment on a case-by-case basis. In doing so, it does not require the same amount or type of data for all plan amendments. See, e.g., Zemel et al. v. Lee County et al., DOAH Case No. 90-7793 (DOAH Dec. 16, 1992, DCA June 22, 1993)(projections of aquifer thickness and transmissivity do not require the same precision as calculating volume-to- capacity ratios for levels of service on road segments); 1000 Friends of Florida et al. v. Department of Community Affairs et al., DOAH Case No. 04-4492GM, 2005 WL 995004 at *15 (DOAH April 28, 2005, DCA May 9, 2005)("a numeric analysis is not necessary to justify industrial uses since they may be goal- based and aspirational"). For example, if amendments merely represent a policy or directional change and depend on future activities and assessments (i.e., further analyses and decision-making by the local government), the Department does not require the degree of data and analyses that other amendments require. (These amendments have sometimes been referred to as aspirational amendments. See Collier County v. City of Naples et al., DOAH Case No. 04-1048GM, 2004 WL 1909265 at *5 and *6 (DOAH Aug. 24, 2004, DCA Dec. 28, 2004)). Conversely, amendments which are mandatory in nature, that is, amendments which are required to be implemented by Chapter 163, Florida Statutes, or Florida Administrative Code Chapter 9J-5, require more data and analyses. Thus, under Department interpretations of the relevant statutory and rule provisions, if an amendment does not have an immediate impact on the provision of services in the unincorporated area, is policy- based, does not require any capital improvement expenditures at the time the amendment is adopted, and simply represents a directional change in the County's long-term water utility planning, it is similar to an aspirational amendment and can be based on less data and analyses than might otherwise be required. Here, the County’s actual policy regarding utility service areas will depend on future activities and assessments. The Amendments do not require the County to take any immediate action. The Amendments do not mandate that existing utility customers in the RSA switch to the County. The Amendments do not authorize any new development in the Rural Tier, and any future development would have to be approved by the Board of County Commissioners through the normal development approval process. Therefore, the Amendments are akin to an aspirational amendment and do not require the degree of data and analyses that are required for other amendments. The County Staff Report identifies, albeit in brief fashion, data and analyses in support of the Amendments. It provides, among other things, that the Amendments are necessary because "[t]he lack of County participation as a service provider has created a void in effective long-term utility planning, resulting in duplicative service lines, inefficient services in the RSA, overlapping utility jurisdictions and, absence of some written agreements defining service areas." The Staff Report further identifies the County’s authority to provide service and the necessity for the Amendments to allow the County to provide service to the Biotechnology Research Park in northwest Palm Beach County. In addition, a number of documents presented at hearing provide data and analyses in support of the Amendments. In considering these documents, the undersigned notes that all data or analysis available and existing at the time of the adoption of the plan amendment may be relied upon to support an amendment in a de novo proceeding and may be raised or discussed for the first time at the administrative hearing. Zemel, supra; McSherry et al. v. Alachua County et al., DOAH Case No. 02-2676GM, 2004 WL 2368828 at *54 (DOAH Oct. 18, 2004, DCA May 2, 2005); Melzer et al. v. Martin County et al., DOAH Case Nos. 02-1014GM and 02-1015GM, 2003 WL 2150756 at *33 (DOAH July 1, 2003, DCA Sept. 26, 2003 and Oct. 24, 2003). The District's Districtwide Water Supply Assessment identifies future potable water demands for various utilities in the County. The District's Lower East Coast Regional Water Supply Plan describes the available raw water supply to meet future demands in the County. The District's CUP-CERP (Consumptive Use Permit-Comprehensive Everglades Restoration Plan) Guiding Principles lists interim water use permitting guidelines, which indicate utilities may experience problems obtaining permitted allocations beyond what is needed to meet their 2005 demands. District Water Use Permit 50- 00135-W is the County's 20-year water use permit, which confirms that the County is the only utility in the unincorporated area with a guaranteed, long-term potable water allocation. The information contained in these documents confirms the County's ability to act as the default water utility provider in the unincorporated area. The County Linking Land Use and Water Supply Plan, Water and Wastewater Master Plan, Reclaimed Water Master Plan, Raw Water Master Plan, 20-Year Wastewater Collection System Master Plan, and Projected Yearly Capital Expenditures each provide data and analysis, which support the County's ability to serve as the default utility provider in the unincorporated area. As a water management district study, the District's documents are professionally accepted sources, which constitute appropriate data and analyses under Florida Administrative Code Rule 9J-5.005(2)(c). Similarly, the County's reports constitute existing technical studies, which are also appropriate data and analysis. Petitioners contend that the County was required to collect new data and prepare a comparative analysis of the County Water Utilities Department and other utility providers in the unincorporated area. However, according to Florida Administrative Code Rule 9J-5.005(2)(b), local governments are not required to collect new data in support of a plan amendment. Further, neither Florida Administrative Code Rule 9J-5.005(2) nor Section 163.3177, Florida Statutes, requires a comparative analysis. It is at least fairly debatable that the Amendments are supported by relevant and adequate data and analyses. Intergovernmental Coordination Petitioners also contend that in order to comply with the Intergovernmental Coordination Element of the Plan, the County must inventory and analyze the facilities and services provided by other utility providers in the areas affected by the Amendments. In other words, they contend that without data and analysis relative to other providers, the coordination function is incapable of being done and is meaningless and renders the Amendments inconsistent with Florida Administrative Code Rule 9J-5.015. (That rule sets forth in detail the data requirements upon which the element in a local government's comprehensive plan must be based, and the goal statements, specific objectives, and policies which must be found in the element.) Section 163.3177(6)(h), Florida Statutes, and Florida Administrative Code Rule 9J-5.015 set forth requirements for the intergovernmental coordination element of a comprehensive plan. The existing Intergovernmental Coordination Element has been found to be in compliance. The Amendments do not modify this element. Although not required for purposes of compliance, the County followed intergovernmental coordination procedures in the comprehensive plan when adopting the Amendments. The Amendments were submitted to IPARC for review by member governments prior to their consideration by the Board of County Commissioners. The County met with other utility providers and interested persons no less than 37 times to discuss the Amendments. Further, Petitioners' own witnesses concede that their representatives attended multiple meetings with the County regarding the Amendments. Such efforts demonstrate that the County substantively complied with the Intergovernmental Coordination Element. Petitioners' contention that these meetings were not conducted in good faith has been rejected. Petitioners implicitly suggest that intergovernmental coordination means acquiescing to the position of an objector. If this were true, adjacent local governments would have veto power over the County's ability to enact plan amendments, a result not contemplated by the statute. The intergovernmental coordination requirements of Section 163.3177(6)(h), Florida Statutes, and Florida Administrative Code Rule 9J-5.015 do not require that local governments resolve all disputes regarding a comprehensive plan and its amendments to the satisfaction of all interested persons, but only that the local government take into consideration input from interested persons. See, e.g., Department of Community Affairs et al. v. Lee County et al., DOAH Case Nos. 89-1843GM and 90-7792GM, 1990 WL 749359 (DOAH Jan. 7, 1993, Admin. Comm. Feb. 10, 1994). The numerous meetings held by the County demonstrate adequate consideration of opposing views. It is at least fairly debatable that the County satisfied the intergovernmental coordination requirements of Section 163.3177(6)(h), Florida Statutes. Economic Feasibility/Comparative Analysis Petitioners argue that the Amendments fail to comply with Section 163.3177(2), Florida Statutes, which requires that "the comprehensive plan shall be economically feasible." Petitioners claim that in order to establish economic feasibility, the County first should have conducted a comparative economic analysis of the cost of utility service in the unincorporated area by various existing and hypothetical service providers. However, this construction of the statute is at odds with the Department's interpretation. The Department does not interpret the economic feasibility requirement of Section 163.3177(2), Florida Statutes, as requiring such a comparison. Instead, it construes the statute as only requiring that a plan amendment be realizable in financial terms, that is, that the local government has the financial ability to achieve what is specified in the amendment. See Resolution Trust Corp. v. Department of Community Affairs et al., DOAH Case No. 94- 5182GM, 1995 WL 1052797 *6 (DOAH April 19, 1995, Admin. Comm. Sept. 4, 1998)("Economic feasibility means plans should be realizable in financial terms."). Compare Southwest Fla. Water Mgmt. District et al. v. Charlotte County et al., 774 So. 2d 903, 916 (Fla. 2d DCA 2001), where the Court interpreted the use of the term "economically feasible" in a proposed Basis of Review provision as meaning "financially feasible or financially 'doable' . . . [and the] financial ability of a WUP applicant to institute reuse." The Department's interpretation of the statute was not shown to be unreasonable or clearly erroneous. The evidence shows that the Amendments are financially realizable. The County Water Utilities Department is one of the financially strongest utilities in the nation. It has the highest municipal bond rating (AAA) granted by the three major rating agencies. As of August 24, 2004, no other utility in the State of Florida had achieved an AAA rating from the three bond rating agencies, and the County Water Utilities Department is among only a handful of utilities nationwide to have achieved that status. Petitioners have acknowledged that the County is a very strong utility from a financial perspective. Given the County's strong financial state, it is qualified and able to serve as the default provider in the unincorporated area. In summary, it is fairly debatable that the Amendments are economically feasible as the term is used in Section 163.3177(2), Florida Statutes, because the County has the financial ability to extend utility service to the unincorporated area. Urban sprawl Wellington (but not the other Petitioners) essentially contends that the Amendments will promote urban sprawl because the County will now allow new urban services (water and wastewater) into undeveloped areas thereby resulting in urban development. Florida Administrative Code Rule 9J-5.006(5) contains standards discouraging the proliferation of urban sprawl. Existing provisions in the Plan, including the Managed Growth Tier System, prevent urban sprawl within the County. Florida Administrative Code Rule 9J-5.006(5)(k) provides in part that "if a local government has in place a comprehensive plan found in compliance, the Department shall not find that plan amendment to be not in compliance on the issue of discouraging urban sprawl solely because of preexisting indicators if the amendment does not exacerbate existing indicators of urban sprawl within the jurisdiction." The Amendments do not affect existing growth management provisions in the Plan and thus will not exacerbate urban sprawl. Although not required, the amendment of FLUE Policy 1.4-k, which Petitioners did not challenge, will also have the effect of maintaining the status quo with respect to urban sprawl. At the same time, the Amendments do not directly or indirectly authorize new development and are only aspirational in nature. Any extension of water and sewer lines into the unincorporated area does not necessarily create urban sprawl because development is not automatically authorized by these activities. Even Wellington's planning expert concurred that urban sprawl is not caused by the provision of utility services, but by the Board of County Commissioners' approval of development orders. It is at least fairly debatable that the Amendments will not encourage urban sprawl in contravention of the Plan.2 Internal consistency Petitioners next contend that the Amendments fail to comply with Sections 163.3177(2), 163.3177(10)(a), and 163.3187(2), Florida Statutes, and Florida Administrative Code Rule 9J-5.005(5), which require that all elements of a comprehensive plan be consistent with each other. In addressing this objection, only those inconsistencies expressly alleged in their Petitions and Amended Petition will be considered. See, e.g., Heartland Environmental Council v. Department of Community Affairs et al., DOAH Case No. 94- 2095GM, 1996 WL 1059751 at *19 (DOAH Oct. 15, 1996; DCA Nov. 25, 1996). Future Land Use Element Petitioners first contend that the Amendments are inconsistent with Goal 3, Objective 3.1, and Policies 3.1-a and 3.1-b of the FLUE. These provisions require that the County "define graduated service areas for directing services to the County's diverse neighborhoods and communities in a timely and cost-effective manner"; that the County establish graduated service areas "to distinguish the levels and types of services needed within a Tier, consistent with the characteristics of the Tier," which include "the need to provide cost effective services"; that the County establish Urban, Limited Urban Service, and Rural Service Areas based on several factors in Table 3.1.1, including "[t]he cost and feasibility of extending services"; and that the County review minimum levels of service "during preparation of the Evaluation and Appraisal Report [EAR] and the Comprehensive Plan as amended." The latter provision also requires that each service provider determine the maximum and available capacity of their facilities and services for this review. The first broad goal is implemented through the County's existing Managed Growth Tier System and is not affected by the identity of the utility provider. Also, the Amendments do not alter the Managed Growth Tier System, nor do they alter the existing minimum levels of service required for the RSA. Similarly, FLUE Objective 3.1 is not affected, as the Amendments only have the potential to change the utility provider in certain areas, and not the level of service provided within the RSA. Further, the Amendments do not change the existing service area boundaries and established service area definitions. As to Policy 3.1-a, the service areas have been established and found in compliance and the Amendments do not alter the service area designations or Table 3.1-1. Therefore, they are not inconsistent with Policy 3.1-a. Finally, Policy 3.1-b is not affected by the Amendments because the minimum levels of service are not altered and the Amendments are not the product of an EAR. Capital Improvements Element – Table 10 Table 10 of the CIE describes water and sewer revenues, operating revenues, federal/state grants, other revenues, bond/ loan proceeds, fund balances, total water and sewer revenues, water and sewer operating expenditures, water and sewer capital projects, annual surplus/deficit, and cumulative surplus/deficit for fiscal years 2004-2009. Petitioners contend that the Amendments are inconsistent with this provision because the Table has not been amended to reflect the expenditures that will be made by the County as a result of the Amendments. This Table is not affected because the Amendments do not require any changes to the County's capital expenditures. If changes do occur as a result of the County's planned extension of utility service into the unincorporated area, the capital improvements associated with extension of service will be addressed in subsequent annual updates of Table 10. Intergovernmental Coordination Element Petitioners contend that the Amendments are inconsistent with Goal 1 and Objective 1.1 of the Intergovernmental Coordination Element, which require the County to "provide a continuous coordination effort with all affected governmental entities" and to "utilize existing mechanisms to coordinate planning efforts with the plans of school boards, other units of local government providing services, adjacent municipalities, adjacent counties, the region, the State, and residents of Palm Beach County." Petitioners essentially claim that the Amendments were adopted and transmitted without coordination with other local governments, as required by the goal and policy. As explained above, the evidence shows that the Amendments were submitted to IPARC for review by each of the local governments and special districts located in the County, these entities were given ample opportunity to comment or object to the Amendments, and the County utilized existing mechanisms to coordinate planning efforts. Therefore, the Amendments are consistent with these portions of the Intergovernmental Coordination Element. Petitioners also contend that the Amendments conflict with Goal 4, Policy 4.1-a, and Policy 4.1-b of the Intergovernmental Coordination Element. The broad goal relates to coordination of "service provision to assure the most effective and efficient service delivery for the residents of Palm Beach County and its municipalities," while the two policies require that the County coordinate with special taxing districts and each municipality within the County during "the concurrency management and development review processes" and in defining the "ultimate boundaries of that entity's sewer and water service areas." The Amendments are consistent with the goal because their purpose is to create more effective and efficient service delivery by encouraging utility providers to enter into agreements which establish exclusive service areas and eliminate overlapping service areas. For similar reasons, the Amendments are consistent with Policy 4.1-a because the County coordinated with each of the special taxing districts through IPARC and numerous subsequent meetings relating to the Amendments. Finally, the main purpose of the Amendments is to prevent overlapping utility service areas and to encourage utility providers to enter into agreements defining service areas. Therefore, they are not inconsistent with Policy 4.1- b. Treasure Coast Regional Planning Council Plan Petitioners next allege that the Amendments are inconsistent with Goal 8.1, Regional Strategy 8.1.1, and Regional Policies 8.1.1.3 and 8.1.1.4 of the Treasure Coast Regional Planning Council's Regional Policy Plan (Regional Policy Plan). In order for a plan amendment to be consistent with a regional policy plan, Section 163.3177(10)(a), Florida Statutes, requires that plan amendments be consistent with the regional plan "as a whole," and that no specific goal or policy be "applied in isolation from the other goals and policies in the plans." Because the Petitions and Amended Petition do not allege that the Amendments are inconsistent with the Regional Policy Plan as a whole, their challenge must necessarily fail. See, e.g., 1000 Friends of Florida, Inc., supra at *38. Even if a provision in the Regional Policy Plan could be viewed in isolation, the Amendments are consistent with Regional Goal Regional Goal 8.1, which requires "public facilities which provide a high quality of life." Nothing in the Amendments would impair the provision of a high quality of life. One of the purposes of the Amendment is to more efficiently provide utility service by defining service areas and improving the provision of services. Regional Strategy 8.1.1 relates to the provision of "levels of public service necessary to achieve a high quality of life cost-effectively." The Amendments are not inconsistent with this strategy, as they are designed to help the County implement the existing objectives and policies relating to this strategy. The purpose of Regional Policy 8.1.1.3 is to "encourage patterns of development which minimize the public cost of providing service, maximize use of existing service systems and facilities and take into full consideration environmental/ physical limitations." As stated above, one purpose of the Amendments is to provide more efficient and cost-effective utility service by encouraging providers to enter into agreements that prevent overlapping service areas and avoid duplication of services. Finally, the purpose of Regional Policy 8.1.1.4 is to "develop local Capital Improvement Programs which maximize development of existing systems before allocating funds to support new public facilities in undeveloped areas." Because the Amendments do not alter the County's Capital Improvement Programs, they do not implicate this policy. State Comprehensive Plan Petitioners further allege that the Amendments are inconsistent with two goals in the state comprehensive plan, which are codified in Section 187.201, Florida Statutes. Like regional policy plans, Section 163.3177(10)(a), Florida Statutes, provides that for purposes of determining consistency, the state plan is to be construed as a whole, with no specific goal or policy applied in isolation from the other goals and policies. If a plan appears to violate a provision of the state plan, a balanced consideration must be given to all other provisions of both the state and local plan to determine whether a local comprehensive plan is consistent with the state plan. Petitioners have not alleged that the Amendments are inconsistent with the state comprehensive plan as a whole. Therefore, their challenge to the Amendments must necessarily fail. See 1000 Friends of Florida, Inc., supra; Heartland Environmental Council, supra. Assuming that a provision within the state comprehensive plan can be viewed alone, Section 187.201(17)(a), Florida Statutes, provides that "Florida shall protect the substantial investments in public facilities that already exist and shall plan for and finance new facilities to serve residents in a timely, orderly, and efficient manner." Petitioners contend that because the Amendments fail to protect the public facilities that already exist in the unincorporated area of the County, the Amendments conflict with this goal. The Amendments are not inconsistent with this goal because their purpose is to implement the Plan provisions in a timely, orderly, and efficient manner. Further, the Amendments are consistent with the specific provisions of Section 187.201(17)(b), Florida Statutes. Petitioners also allege that the Amendments contradict the requirements of Section 187.201(20)(a), Florida Statutes, which deals with cooperation between levels of government, elimination of needless duplication, and promotion of cooperation. Again, the purpose of the Amendments is to eliminate duplication and promote cooperation between entities by encouraging utility providers to enter into interlocal agreements with the County that define exclusive service areas and prevent duplication of services. Further, the Amendments are consistent with the specific provisions of Section 187.201(20)(b), Florida Statutes. Other Objections Finally, any other contentions raised in the Petitions and Amended Petition not specifically addressed herein have been considered and found to be without merit.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Community Affairs enter a final order determining that the Amendments adopted by Ordinance No. 2004-026 on August 24, 2004, are in compliance. DONE AND ENTERED this 18th day of July, 2005, in Tallahassee, Leon County, Florida. S DONALD R. ALEXANDER 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 18th day of July, 2005.
Findings Of Fact The Petitioner, Bocilla Waterways, Inc., is a corporate entity formed for the purpose of pursuing the subject project and installing the proposed channel. Randall Craig Noden, secretary- treasurer of that corporation, and a director of it, is a realtor who sells and develops property on Don Pedro Island, in the vicinity of the proposed project. He and other officers and directors of the Petitioner corporation have an interest in property on some, but not all, upland areas adjacent to Bocilla Lagoon, Old Bocilla Pass and Kettle Harbor, the water bodies germane to this proceeding. The Respondent, State of Florida, Department of Environmental Regulation, is a state agency charged with regulating dredge and fill projects in state waters and navigable waters pursuant to Chapters 253 and 403, Florida Statutes, and Rule Chapters 17-3 and 17-4, Florida Administrative Code. The Intervenor, Environmental Confederation of Southwest Florida (ECOSWF), is an incorporated, not-for-profit organization whose membership includes numerous environmentally concerned public interest organizations or associations located throughout southwest Florida. Members of the Intervenor use Old Bocilla Pass, Kettle Harbor, Bocilla Lagoon and Lemon Bay, an adjacent contiguous water body, for boating, swimming, fishing (both recreational and commercial), and collecting shellfish. Some of the membership of the Intervenor live in the immediate area of the proposed project. Project Description The Petitioner submitted a dredge and fill permit application to the Respondent, DER, proposing excavation of an access channel through the uplands of Don Pedro Island and adjacent transitional and submerged lands. The channel would be 100 feet wide, 450 feet long and dredged to a depth of -5.0 feet mean low water, with 2:1 side slopes grading to 3:1 at approximately +0.5 feet NGVD. The channel below mean high water would be 70 feet wide' and 670 feet long to a depth of -5.0 feet mean low water, with 2:1 side slopes. A rip-rap strip five feet wide would be placed in the littoral zone on either side of the channel. As originally proposed, the channel excavation would be performed by dragline and clamshell with spoil placed upon uplands for disposal. The excavation would progress from the west side of the project to the east, with plugs remaining at the eastern terminus of the channel until it stabilizes and the rip- rap is placed along the excavated channel. A turbidity curtain is proposed to be used to maintain water quality above state standards regarding turbidity. The applicant originally proposed to transplant seagrasses, displaced in the excavation process, back into the bottom of the excavated channel. Earthen slopes above mean high water would be vegetated in order to achieve stabilization. Some of these proposals were modified after negotiations with DER staff, such that the seagrass transplanting portion of the project would be accomplished in surrounding areas of the water bottom of Bocilla Lagoon and Kettle Harbor, specifically, bare areas and otherwise degrassed, vegetated flats. The applicant also proposes to install navigation aides in Bocilla Lagoon and Kettle Harbor in order to help maintain boat traffic in the channel, and to facilitate ingress and egress through the proposed channel. Don Pedro Island is a barrier island lying off the coast of Charlotte County, Florida. The only access to the island is by boat or helicopter. Bocilla proposes to excavate the proposed channel in order to, in part, provide better navigational access to Bocilla Lagoon which lies within Don Pedro Island. There is presently a navigational channel in the Bocilla Lagoon through what is called "Old Bocilla Pass," located at the north end of Bocilla Lagoon and communicating with Lemon Bay. Bocilla contends that the channel is somewhat tortuous and subject to shoaling, with concomitant grassbed damage by boat propellers, and that thus, a better navigational access in the form of a shorter, deeper, more direct channel from the southern end of Bocilla Lagoon to Kettle Harbor is required. The project would involve the removal of approximately .18 acres of mangroves (red and black mangroves) and .187 acres of seagrasses. Bocilla has proposed to mitigate the damage involved in the mangrove and seagrass removal by replanting mangroves, on three foot centers, along both sides of the proposed channel, and replanting or transplanting seagrasses in bare areas of Kettle Harbor, near the proposed project. Description of Pertinent State Waters Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass are designated as Class II, navigable waters of the state and are designated for shellfish propagation or harvesting. Shellfish, including clams and oysters, occur in Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass. As demonstrated by Intervenor's witnesses Wade, Cole and Wysocki, shellfish are harvestable and harvested in Bocilla Lagoon and Kettle Harbor at the present time. Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass have also been conditionally approved by DNR for shellfish harvesting. DNR approves or prohibits waters for shellfish harvesting, and as a matter of policy generally prohibits shellfish harvesting in manmade "dead-end" canals. A "conditionally approved" water body, such as those involved herein, is an area approved for shellfish harvesting, but one which is more likely to be affected by pollution events. Thus, they are monitored more closely by DNR. Such events as additional residential development in an area, resulting in more septic tank sewage discharge, on-board toilet discharges from boats or the installation of a water and sewer treatment plant, can result in DNR temporarily or permanently closing a conditionally approved area to shellfish harvesting. Natural phenomenon such as the influx of red tide is also a factor which is considered by DNR in electing to classify a shellfish harvesting area as conditionally approved, and in electing to prohibit shellfish harvesting in an area. It was established through testimony of witnesses Feinstein and Setchfield of DER that long-standing DER policy provides that when DNR conditionally approves waters as being shellfish harvestable, that means they are "approved" for all shellfish harvesting purposes, but simply subjected to closer monitoring and with an increased likelihood of closure due to immediate pollution events. Therefore, the prohibition in Rule 17- 4.28(8)(a), Florida Administrative Code, prohibits issuance of dredge and fill permits in areas approved for shellfish harvesting or "conditionally" approved, since there is no difference in the "shellfish harvestable" nature of the waters until a closure occurs, which may simply occur sooner in conditionally approved waters. Bocilla Lagoon and Kettle Harbor are both naturally- formed water bodies, although some dredging has been allowed to occur in them in the past. They are not manmade, "dead-end" canals. Neither water body has the physical or biological characteristics of a "typical dead-end canal". Both are quite high quality habitats for the natural flora and fauna occurring in the marine environment in that area, and thus the general policy of DNR established by witnesses Cantrell, Fry, Feinstein and Sperling which prohibits shellfish harvesting in manmade, dead-end canals, does not apply to Bocilla Lagoon and Kettle Harbor. The water quality in both bodies of water is good and within DER standards generally. At times however, the water quality in Kettle Harbor suffers from a failure to meet DER dissolved oxygen standards contained in Chapter 17-3, Florida Administrative Code. Indeed, the water quality in Bocilla Lagoon is generally somewhat better than the water quality in Kettle Harbor. Environmental Impacts The project as currently proposed would result in the removal of approximately .18 acres of mangroves and .18 acres of seagrasses. Seagrasses and mangroves are important in providing areas of cover, food, and habitat for various estuarine species. Seagrasses serve to stabilize marine soils resulting in a decrease of suspended solids in contiguous waters with resulting decrease in turbidity in those waters. The loss of seagrasses can result in de- stabilization of the bottom sediment, such that suspended solids or turbidity increases in involved waters, which can result in decreased light penetration to the vegetated bottoms. Decreased light penetration, if of a sufficient degree, can result in the further loss of seagrasses and other bottom flora, causing in turn, increased turbidity and further decreased light penetration, with progressively destructive results to seagrass beds and other marine flora and fauna, with a substantial detrimental effect on the marine biological community in general. Mangroves serve as biological filters, trapping sediments, heavy metals, nutrients and other pollutants, uptaking them through their roots and converting them to usable plant food and thus filtering such harmful elements from state waters and rendering them into environmentally harmless substances. The removal of the mangroves at the proposed channel site will result in a loss of their beneficial effects. These beneficial effects will be absent for a greater period of time than it takes to merely plant replacement mangrove plants, since mature trees will be removed and mangrove seedlings will be replanted in their stead. Maturation of mangroves at this location would take in excess of three years, thus replacement of the beneficial filtering effects of the removed mangroves will take in excess of three years, to which time must be added the time which lapses between the original mangrove removal and the replanting of the seedlings, which would start the maturation period. Bocilla proposes to mitigate the removal of the mangroves by that replanting, as well as to transplant seagrasses removed from the channel site to other nearby areas currently bare of seagrass. Seagrass replanting is not a well-established practice. Compared to mangrove replanting, there is less experience, less information and a lower success ratio historically. Of the hundreds of dredge and fill projects occurring and approved throughout Florida, only three have involved replanting of removed seagrasses. Two of the projects involved the Port of Miami in Dade County and the "New Pass site" in Sarasota County. In both of these cases, seagrass replanting cannot be termed successful. The Port of Miami project resulted in a final survival rate of only twelve per cent of ,the grasses replanted. The New Pass project thus far has resulted in a survival rate of only 39 per cent of the seagrasses replanted, after only nine months. The Petitioner proposes that the replanting be accomplished by Mangrove Systems, Inc. That firm is headed by Robin Lewis, who oversaw the seagrass replanting project at the New Pass area in Sarasota. The location and method of replanting seagrasses at New Pass, as to water depth, type of bottom, type of grass and planting method, was generally similar to that proposed for the Bocilla project. That is, it would be accomplished by "plug planting," of "bald" spots at generally the same latitude and similar water depth. The survival rate at the end of six months at the New Pass project was 73 per cent. The survival rate at the end of nine months was 39 per cent. Mangrove Systems, Inc. and Mr. Lewis acknowledges that it is difficult to attribute the decrease in survival rates and grass shoot densities to any one cause, but that predation and a shift in sediments due to the vagaries of water currents, were probably the chief causes for the decrease in seagrass survival. Mangrove Systems, Inc. and the Petitioner propose a guarantee whereby Mangrove Systems, Inc. would replant more seagrasses, if needed, if a low survival rate occurs, which it defines to mean less than a 70 to 80 per cent survival rate after one or two years. There is no guarantee concerning the survival rate after a second planting, however. It was not established when the survival rate will be measured, in determining whether a 70 to 80 per cent survival is being achieved. In this connection, the central Florida coast where the Bocilla project is proposed, is not as conducive to seagrass growth as other more tropical marine areas, such as in the Florida Keys. In the area of the proposed project, seagrasses do not generally produce a great deal of seed and tend not to grow back very readily, once they are destroyed. Seagrasses in the Florida Keys tend to have, in comparison, much greater seed production and for this and other reasons, tend to reproduce themselves more readily once destroyed. They tend to be more amenable to transplanting in the Florida Keys marine environment. Mangrove Systems, Inc. has conducted a seagrass replanting project in the Florida Keys, however. One-third of the seagrasses planted in that project have not survived after two years. In short, the likelihood of seagrass survival has been insufficiently tested in the geographical area and latitude and in similar soils, water depths and temperatures as those involved in the instant case, such that reasonable assurance of adequate seagrass survival with the replanting project proposed will occur. Hydrographics and Maintenance Dredging The evidence is uncontradicted that the opening of the proposed channel would increase circulation in the southern end of Bocilla Lagoon. Increased circulation tends to have good effects in that it reduces stratification in water bodies. Stratification is a condition which occurs when the deeper waters of a given water body do not interchange with surface waters, but rather stratify or become characterized by layers of differing levels of dissolved oxygen, temperature, pH, etc. Typically, lower levels of a stratified body of water are characterized by low levels of dissolved oxygen. The present water quality of Bocilla Lagoon however, is not characterized by statification in any significant degree. It is very similar in water quality, in terms of dissolved oxygen, temperature, pH and other Chapter 17-3 water criteria, to that water quality of the nearby intra-coastal waterway into which the channel into and through Kettle Harbor would open. The intra-coastal waterway is agreed to be a well- circulated body of water, meeting all current State water quality standards. Accordingly, the opening of the channel and the increased circulation it may cause in the southern end of Bocilla Lagoon would have minimal, positive benefits. The change in circulation and in water current patterns and velocities caused by the opening of the direct, shorter channel from lower Bocilla Lagoon and Kettle Harbor may, negatively affect the present seagrass growth in seagrass beds in Kettle Harbor and Bocilla Lagoon in the vicinity of each end of the proposed channel, due in part to increased current velocities that would result from tidal exchange through the shorter, straight channel which would be opened. The expert witnesses in the area of hydrographics disagreed on the effect of the proposed channel on water circulation in the northern end of Bocilla Lagoon and Old Bocilla Pass, which is the north channel opening into northern Bocilla Lagoon. Witness Sperling for the Department opined that a major reduction in flows through Old Bocilla Pass channel would occur. Witness Tackney for the Petitioner acknowledged there would be some reduction in flow, and witness Olsen opined that a reduction in flow would occur, but there could also be an increase in circulation. Both witnesses Tackney and Olsen, in opining that a flow-through, enhanced circulation and flushing system may result from installing the channel, based that opinion to a significant degree, on their belief on the effects of wind on forcing water through the Pass and Bocilla Lagoon. No wind data or records were adduced however, to show the likely effects of wind on creating the Petitioner's desired "flow-through" system. Witness Sperling disagreed as to the significance of this flow-through effect, but there was no disagreement among the hydrographic experts that reduced flows through Old Bocilla Pass, which all acknowledged can occur to one degree or another, can result in increased sedimentation in Old Bocilla Pass, which can result in turn, in the need for increased maintenance dredging in Bocilla Lagoon and Old Bocilla Pass in the future. Maintenance dredging in Old Bocilla Pass may have to be increased if the proposed channel is constructed. The proposed channel itself will likely have to be periodically maintenance dredged as well. Maintenance dredging can cause environmental problems. Dredging activities result in the loss of marine habitat and the destabilization of marine sediments, with resulting increased turbidity and reduced photic effects, with concomitant detrimental effects on seagrasses and other bottom flora and fauna. Increased turbidity resulting from dredging and destabilization of sediments can directly adversely affect shellfish, including clams and oysters. Dredging impacts and siltation can negatively affect seagrass growth and water quality by increasing turbidity resulting in reduced photosynthesis in seagrass, by smothering the seagrass directly and by silting fauna and vegetation in adjacent productive grassbeds. Persons other than the officers and directors of Bocilla Waterways, Inc. own property and have riparian rights on the Old Bocilla Pass channel. These persons have in the past, and have the right in the future, to use Old Bocilla Pass for navigational purposes and could elect to maintenance dredge Old Bocilla Pass as they have in the past. If the proposed channel is constructed, there is obviously a more direct access and shorter water route between the waters of Bocilla Lagoon and Kettle Harbor. Water quality at times in Kettle Harbor has been worse than that in Bocilla Lagoon, especially in terms of low dissolved oxygen. If poorer water quality exists in Kettle Harbor due to low dissolved oxygen, an influx of red tide or some other cause, the construction of the proposed channel would increase the chance, by the more direct connection and increased flow in the southern end of Bocilla Lagoon, to contaminate the water of Bocilla Lagoon. The Public Interest Public opposition was expressed at the hearing, including that of ECOSWF, the Intervenor, some of whose members include people who live in the area of the proposed channel and use the involved waters. Local fishermen who harvest shellfish and finfish in Bocilla-Lagoon and Kettle Harbor, and use Old Bocilla Pass for navigation between Lemon Bay and Bocilla Lagoon, oppose the project, some of whom are members of the organized Fishermen of Florida, an association of approximately 25,000 members. Residents of Bocilla Lagoon and the immediate area, who habitually navigate Old Bocilla Pass, including local fishermen, have had little trouble navigating Old Bocilla Pass because they are familiar with the channel. Although the Petitioner alleges that the new channel is needed in part for the safety of people living on Bocilla Lagoon to assure quick access to the mainland in case of medical emergencies, the members of the public living on Bocilla Lagoon, (with one exception) and on surrounding areas of the island, do not wish such increased access for medical purposes. The island is presently reached from the mainland by either watercraft or helicopter. Formerly, there was a bridge connecting the island with the mainland which has since been destroyed, and not rebuilt. The residents living on Bocilla Lagoon, either full- time or part-time, buy their homes and choose to live there with knowledge of the present mode of access through Old Bocilla Pass, which is also the means they would achieve access to the mainland in case of medical emergencies or, alternatively, by helicopter transport or by transport over island roads to the ferry landing, with access to the mainland by ferry. The residents, in general, desire to maintain the isolation of life on the island as it presently exists and do not desire enhanced access between the island and the mainland, since part of the charm of having homes and living on the island is its isolation from the more populous mainland. Other than the testimony of Petitioner's witnesses, there was no testimony presented expressing any public need for the proposed channel, as for instance from public officials having knowledge of any medical or public health need for enhanced access to Bocilla Lagoon and the island. The proposed project is contrary to the public interest due to its adverse effects on seagrasses, shellfish, and water quality as delineated above. The adverse effects on seagrasses would result from the dredging itself and the destruction of a portion of the extant seagrass beds, and the resultant likelihood of poor survival rates in the attempted transplanting of seagrass as a replacement for that destroyed by the channel dredging. The proposed project is not in the public interest of those people with riparian rights on Old Bocilla Lagoon and northern Bocilla Lagoon, as there is substantial likelihood the proposed project will reduce flows through Old Bocilla Pass' channel with the resultant increased settling out of sediment and thus increased shoaling of that channel, which would concomitantly increase the need for maintenance dredging in Old Bocilla Lagoon and channel. Additional maintenance dredging and the possible negative effects of such additional dredging on marine, flora and fauna in Bocilla Lagoon and Old Bocilla Pass constitute an additional burden on these riparian owners, the bearing of which is not in their interest. The proposed project is also contrary to the public interest in that the proposed channel is deeper, wider and more direct as an entry into Bocilla Lagoon from Kettle Harbor and Lemon Bay, and would thus allow larger, deeper draft boats to enter Bocilla Lagoon with concomitant increased pollution from oils, greases and possible discharge of onboard sewage, which could have adverse environmental impacts on water quality in Bocilla Lagoon, as well as Kettle Harbor. The use of deeper draft, larger boats with larger propellers and more powerful engines could also result in damage to adjacent grassbeds in the vicinity of either ends of the proposed channel, either through direct propeller contact or through prop wash, when such boats are navigated in areas minimally deep enough to accommodate their draft. Since the installation of the proposed channel would result in a deeper, more readily used access to Bocilla Lagoon by larger boats with the remaining original channel usable also, at least for a time, there is a-substantial likelihood of increased residential development on riparian property around Bocilla Lagoon. This could have the result of reducing water quality in the lagoon, or potentially so, through septic tank leachate, stormwater runoff and other adverse environmental effects, such that the water in the lagoon traditionally approved for shellfish harvesting may be prohibited in the future.

Findings Of Fact Background On January 29, 1981 respondent/applicant, George H. Hodges, Jr. (applicant or Hodges), filed application number 16 39644 with respondent, Department of Environmenta1 Regulation_ (DER), seeking a dredge and fill permit to generally authorize the excavation of 26,000 cubic yards of material from a 3,700 foot portion of an existing channel (Old Pablo Creek) just west of the Intracoastal Waterway (ICW) in Jacksonville, Florida. The channel then proposed was a straight channel along the northern boundary of his property. Hodges also sought to construct two boat slips, three floating docks, an 850 foot vertical bulkhead adjacent to the docks, and to dispose of all dredged material in a diked upland site. Thereafter, DER informally advised applicant that it intended to deny the application for various reasons, including the fact that the dredging would eliminate .75 acres of marsh and wetlands. After receiving this advice, Hodges proposed a series of amendments to his application in 1984 and 1985 in an effort to counter and satisfy DER's objections. The final amendment was made on September 10, 1985. As finally amended, Hodges proposed to confine all dredging to existing salt channels, thereby eliminating the objection that adjacent marshes would be destroyed. Applicant also proposed to restrict his dredging to only 2,250 feet along the northern portion of Old Pablo Creek and to remove 29,250 cubic yards of fill (silt) and sand and place the same in a 12.5 acre upland spoil site. By proposed agency action issued on February 28, 1985, DER announced it intended to issue the requested permit. This prompted a protest and request for hearing from petitioner, Jacksonville Shipyards, Inc. (JSI), which owns and operates a ship repair facility on the ICW just south of the proposed project. In its petition, JSI generally alleged that (a) Hodges had failed to give reasonable assurances that water quality standards would not be violated, (b) the project would adversely affect its property, (c) the project would have an adverse effect on the conservation of fish and wildlife, (d) the project would cause harmful erosion or shoaling, (e) DER failed to consider the long-term effect of the project on marine productivity and the cumulative impact of the project, and (f) the proposed vertical bulkhead did not meet statutory requirements. The Project The project site is a shallow horseshoe shaped creek approximately 3,700 feet in length which meanders through a vegetated salt marsh just west of the ICW in Duval County, Florida. Both ends of the creek connect into the ICW. The site is approximately one-half mile north of the bridge on Atlantic Boulevard which crosses the ICW. The ICW is a man-made channel constructed by the U. S. Corps of Engineers which runs in a north-south direction just east of the project site. It is commonly referred to as Pablo Creek. The channel or creek in which the dredging will occur is known as Old Pablo Creek (creek). An excellent aerial view of the entire area is shown in petitioner's exhibit 4 received in evidence. The creek is a predominately marine water classified as a Class III water of the State. Accordingly, it is subject to DER's regulatory jurisdiction. For purposes of this hearing, the parties have referred to the upper and lower portions of the creek as the northern and southern portions, respectively. Hodges intends to dredge the northern portion of the creek, which measures approximately 2250 feet in length from the ICW to a bend at its western end which crosses Hodges' property and where a residential site is located. According to Hodge's affidavit of ownership, he is the "fee interest owner of adjoining lands except for the dredge channel which is owned by the State of Florida". He acknowledged, however, that the residential site is owned by his superintendent, and that the marshes adjoining the most southern bend in the northern portion of the creek, and the southern portion of the creek, are owned by JSI. Except for the cleared residential site at its western end, the creek is surrounded by vegetation and salt marshes. The vegetated portion of the marsh is marked by a clearly delineated edge which separates it from the creek bottom. The dominant species of vegetation in the marsh are Juncus and Spartina. The marsh serves as a habitat and breeding ground for numerous species, including fiddler crabs, mussels, barnacles, mollusks, faunal communities and gastropods. In addition, the marsh is beneficial because of its biotic productivity and entrapment of nutrients and sediments. For this reason, the habitat should be maintained. Some forty years ago, the portion of the creek that Hodges intends to dredge was eight to twelve feet deep. However, dredging of the ICW by the Corps of Engineers and the placement of fill at the site of the Atlantic Boulevard Bridge have contributed to the shallowing of the creek over time. Today, portions of the creek are exposed and impassable under low tide conditions. Indeed, many parts of the creek are dry during the low tide phase of the ICW. At high tide, the creek is flooded to an approximate depth of four feet. Hodges proposes to dredge the creek channel to a uniform depth of five feet below mean low water (MLW) with side slopes at a 3:1 ratio to restore navigational access from his upland property to the ICW. He has represented that his use of the channel will be restricted to one, or possibly two, small boats for personal use and enjoyment. When completed, the creek channel will have a depth of nine feet at high tide, or an average depth of seven feet over a diurnal cycle. In his amended application, Hodges proposed to confine his dredging to existing creek channels, and to not disturb the actual body of the salt marsh or the vegetation bordering the creek. It is noted that there is no vegetation growing in the existing creek bottom. However, at hearing he conceded that dredging "may include some minor removal of isolated patches of grass growing in the creek channel". One such patch of grass lies in the elbow of the canal which reaches south of Hodges' property, a patch separated from the main body of the marsh by a five foot wide slough deep enough to be navigated at high tide. Hodges estimates this patch of grass to be less than 1/100 of an acre in size (10' x 40') and maintains the effect of its removal would be negligible. The excavation will be effected by means of a Mud Cat hydraulic dredge which operates by suctioning the sediment and water into a pipe. The dredge material (sediment/water mixture) will then be pumped into a series of containment cells on a 12.5 acre upland spoil site that lies approximately one-half mile northeast of the project. Any discharge from the spoil site will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. The natural grade of the existing creek bottom is at or below the mean low water datum. At high tide the existing creek is 4.3 feet deep at its deepest point and gradually slopes upward to a depth of 2.4 feet near the marsh. The elevation of the creek where it meets the marsh is close to mean high water. Even so, the channel width does not always correspond with the mean high water line boundaries of the creek, and creek waters sometimes inundate and extend back into the marsh at high tide. Because Old Pablo Creek is tidally influenced, any water quality violations in the northern portion of the creek can be expected to also have an adverse effect in the southern portion as well. Creek Width Petitioner has raised the issue of whether the creek is as wide as Hodges represents it to be on the drawings attached to the amended application. This is significant since (a) the engineering plans are based upon the assumption that the measurements in the application are correct, (b) the proposed dimensions (depth and side slopes) of the new channel are dependent upon the existing creek having a minimum width of from sixty to eighty feet, as represented by Hodges, and (c) any excavation outside of the existing channel will result in the removal (destruction) of vegetation and marsh. In his application, Hodges reflects the top width of the creek to be sixty to eighty feet, which width will enable him to dredge the channel to an average depth of five feet below MLW, and maintain a side slope ratio of 3:1. This ratio is necessary because of the composition of the sediment in the creek. The minimum top width required to excavate a channel with 3:1 side slopes to a depth of five feet below MLW is fifty- four feet. Petitioner's exhibit 4 identifies five points along the eastern half of the northern portion which have been measured by the parties to determine the actual width of the creek. Although only five points were measured, it may be inferred that these distances are representative of the creek's width throughout its eastern half. At points five through eight, the widths are forty-nine, thirty-five, fifty and fifty feet, respectively, which are less than the measurements contained in the application. If the channel is constructed with the minimum top width (54 feet) required to have 3:1 side slopes, it will result in the elimination of 6 feet of marsh at point 5, 19.5 feet of marsh at point 6, and 4.1 feet of marsh at both points 7 and 8. This equates to the elimination of approximately .33 acres of marsh. Since the above measurements are representative of the eastern half of the northern portion, other areas of vegetation, albeit in unknown proportions, would also have to eliminated. If, for example, applicant attempts to construct a channel within the confines of the portion of the creek that has a top width of only thirty-five feet (point 6), the maximum channel that could be constructed would be V-shaped with a depth of one foot at low tide. Assuming the remaining part of the channel was excavated to -5' MLW, a stagnant area would develop in this portion of the channel and adversely affect water quality. However, to counter the problem at point 6, Hodges intends to remove one patch of grass 10' by 40' in size to achieve the desired width. Any adverse effects on the adjacent marsh at that particular point would be negligible. Because the estimated creek width is not accurate, even the agency now concedes the engineering plans are no longer useful. As a condition to the issuance of a permit, DER has suggested that Hodges be required to submit new certified engineering drawings depicting the proposed cross-section of the channel. It also suggests that the proposed cross-section comply with the top-widths depicted in applicant's exhibit 53, and depict side-slopes of three to one. It further suggests that a condition for the issuance of any permit be a requirement that the 3:1 ratio be maintained, and that other than point 6, no other grass be removed. Finally, the agency proposes that if the new plans and conditions do not permit a -5 MLW depth, the proposed depth be reduced accordingly. However, the evidence supports a finding that either vegetation must be removed at various points along the eastern half of the creek in order to maintain a 3:1 ratio for side slopes, or the depth must be reduced. By reducing the depth at certain points, stagnant areas in the creek will develop, thereby adversely affecting the quality of the water. Further, as noted hereinafter, the validity of the flushing analysis performed by applicant's experts rests upon the assumption that a -5' MLW uniform depth will be used. Finally, the applicant has not given reasonable assurance that the marsh and habitat will not be adversely affected by the elimination of the vegetation which is necessary to achieve the desired depth and concomitant 3:1 ratio. Therefore, the alternative conditions suggested by DER are neither reasonable or appropriate. The Spoil Area The spoil area to be used by applicant is a 12.5 acre upland disposal site approximately one-half mile northeast of Hodges' property. Applicant does not own the upland spoil site but has obtained easements from the owner which expire in March, 1987. In other words, he must complete all work on the project by that date or lose access to the property. The proposed spoil site is completely diked, and is sectioned off into three sections by interior dikes with overflow pipes. Internal baffles and silt fences are also designed into the area. Uncontradicted testimony established that the spoil area is "unusually well designed". Any discharge from the spoil area will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. Discharge, if any, will be outfall from an overflow structure in the third section of the spoil area to a dump area land then by sheet flow to salt marshes adjacent to Greenfield Creek. The vegetation in Greenfield Creek consists of a salt marsh expanse of Spartina alterniTlora and Juncus roemerianus. Both species survive in and are indicative of regular introduction of saline waters, and show high tolerance to varying salinity levels. If saline waters from Old Pablo Creek were introduced into Greenfield Creek, it would have no adverse impact on the Greenfield Creek ecosystem. The size of the site was originally designed for a project of 100,000 cubic yards. The site will retain all |effluent from the dredging. The expected total effluent, both sediment and water, is roughly 5.3 million cubic feet of material, assuming a ratio of 6.7 cubic feet of water for each |cubic foot of sediment dredged. This is slightly lower than the 5.4 million cubic feet total capacity of the site. The supernatant from the discharge being deposited into the first cell of the spoil area will only flow into the next cell when the first cell fills and the level of the supernatant rises above the top of the vertical drain pipe overflow structure. If rainfall events cause the cells to fill with water during dredging and discharge operations, the discharge to the next cell or to Greenfield Creek will be primarily fresh water. This will occur because introduction of fresh rainwater into the brackish water from the dredge area will cause stratification, and the fresh rainwater will form a layer on top that will flow into the overflow structure. Turbidity Effects In removing the mud bottom from the creek to a depth of -5' MLW, some turbidity will occur. This is a natural by- product of using the hydraulic dredge. However, the amount of turbidity, and its effect on the waters at the dredge site and discharge point, are in issue. State water quality standards prohibit the discharge of water with a turbidity level greater than twenty-nine nephelometric units (NTU's) above the background levels of the receiving waters. The evidence indicates that the background turbidity levels at the creek are now in the range of ten to twenty NTV's. Excessive levels can result in adverse effects on local biota such as decreasing productivity by reducing light penetration. Excessive turbidity can also be expected to suffocate organisms. The area to be dredged contains sediment deposited from the surrounding salt marsh and carried in from the ICW. The sediment is composed of 14% clay, with the remainder being sand and silt. This was confirmed by a laboratory analysis conducted by JSI. As a general rule, the coarser the material, the faster it tends to settle out thereby creating less turbidity problems. Therefore, sand, which is of a grain size, can be expected to settle out quickly while silt takes somewhat longer. However, clay size particles are much smaller than silt and do not settle out as easily. Applicant made no laboratory analysis of sediment and consequently he erroneously assumed the mud to be sand and silt, and did not take the clay particles into account. The dredging in the creek will cause the turbidity levels to rise to 150 NTU's. However, the placement of a turbidity screen at the entrance to the ICW will prevent the release of this turbidity into that water body. Therefore, if a permit is issued, such screens should be used by Hodges at the dredge site. At the spoil site, clay size particles will also be included in the matter pumped for discharge. If these particles do not settle out, or are not treated, their discharge into Greenfield Creek (a jurisdictional water) will cause violations of the turbidity standards. To counter their effects, flocculants (chemicals) should be added when necessary to the confined material to aid the particles in settling. If a permit is issued, this should be made a condition in the permit. Dissolved Oxygen Impacts The dissolved oxygen (DO) levels in the creek fluctuate on a daily and seasonal basis. As a general rule, DO levels tend to be lower in warmer weather and during the early morning hours. Therefore, a "worst case" situation will generally occur in the summer months in the early part of the day. State water quality standards contained in Rule 17- 3.121(13), F.A.C., provide that in predominately marine waters, the concentrations of DO "shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter." Sampling conducted by petitioner at 5:00 a.m. in early July, 1986 during high tide revealed readings ranging from 3.06 mg/1 in the western portion of the creek to 4.59 mg/1 at the mouth of the creek. Dissolved oxygen levels in the ICW ranged from 3.94 to 4.68 mg/1. Hodges also sampled the creek and ICW in the late morning or early afternoon on August 6,1986 and determined DO levels to be 4.8 mg/1 in the creek and 5.8 mg/1 in the ICW. Testing at that hour of the day produced higher values than those found by JSI. The readings collectively confirm that DO levels in the creek are approximately 1.0 mg/1 less than the DO levels in the ICW. This deficit is primarily caused by the high oxygen demand exerted by the adjacent marsh and muds in the creek. This situation will not be changed by the dredging. The flushing time of the creek channel is an important factor in predicting post-dredging impacts on water quality. Flushing time determines how rapidly waters of the ICW will exchange and mix with the water in the creek channel. Both Hodges and JSI conducted tidal prism studies to determine how many tidal cycles would be required to flush a hypothetical pollutant to 10% of its initial concentration. Under worst case conditions, the channel is expected after dredging to flush every 3 to 4 tidal cycles or 1.6 days. Under more favorable conditions, the creek is expected to flush every 2 to 3 tidal cycles. This compares with the current system which flushes almost 100% every tidal cycle or once every twelve hours. The increased flushing time is due to the significantly greater volume of water that will enter the creek channel after dredging. Because of increased channel depths, the water will move at a slower velocity. Therefore, the oxygen consuming components have a longer period of time to react in the water column. This in turn will cause reductions in DO levels of between .7 mg/l and 1.5 mg/l in the creek. This was confirmed through tidal prism modeling performed by JSI. In this regard, it is noted that JSI's modeling was more sophisticated, better calibrated, and its assumptions were more accurate and reasonable. Consequently, its testing results are considered to be more reliable and persuasive than that of applicant. It must also be recognized that the deepening of those areas that are currently exposed at low tide will allow water to move more easily through the channel and remove some oxygen demanding sediments that now draw from a shallow water column. This will tend to have a beneficial effect on water quality. However, the overall impact of these beneficial effects is unknown, and it was not demonstrated that the otherwise adverse effect on DO will be offset or minimized by the unmeasured impact of deepening the shallow areas. Therefore, applicant has not given reasonable assurance that water quality standards will not be violated by the project. At the same time, it must be further noted that a reduction in the channel depth due to the smaller width of the creek will alter the results of the tidal prism studies, as well as negate some of the beneficial effects caused by deepening the shallow portions of the channel. To what extent the studies are changed, or benefits will be reduced, is not of record. Other Effects of Project As noted earlier, Hodges intends to use one or two boats on the deepened channel. The use of the boats will not introduce pollutants in any significant quantity. Hodges proposes to construct his docks and place rip- rap on the northern side of the widest portion of the creek channel. Little, if any, vegetation will be eliminated by these activities. The use of rip-rap for the construction of the bulkhead is the most environmentally sound means of bulkheading, and will stabilize the shoreline as well as provide habitat for aquatic organisms. The dredging of the creek channel will improve the navigability of the creek, and permit the use of boats in areas where access is now impossible under low-tide conditions. In addition, the sharp bends in the creek will prevent the operation of boats at high speeds. JSI's concern that boats may run aground once they leave the northern portion and enter the southern portion is not meritorious since few, if any, are expected to use the latter part of the creek, and the sharp bends will force boaters to operate at low speeds. Shoaling or erosion of the southern portion will not result from the proposed activities. Indeed, an increased flushing and introduction of new flow into the system may benefit the northern portion. Any situation occurring in that part of the creek should not exceed the rate of siltation occurring under current conditions. The benthic organisms which populate the bottom of Old Pablo Creek include crabs, mussels, barnacles and other species normally associated with estuarine systems. The removal of the mud bottom in the dredging operation may remove some of these organisms. However, this should not significantly change the habitat of these benthic organisms. Rapid recolonization by these species would be expected with recolonization substantially underway within forty-eight hours
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that application number 16-39644 of George H. Hodges, Jr. for a dredge and fill permit be DENIED. DONE and ORDERED this 2nd day of December, 1986 in Tallahassee, Florida. DONALD R. ALEXANDER, Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 2nd day of December, 1986.
Findings Of Fact Occidental owns land or mineral rights to land over a broad area adjacent to the Suwannee River near Lake City and White Springs in Hamilton County, Florida. Occidental has invested approximately $350 million in the area, and presently has two phosphate mines and two chemical plants in operation. Occidental intends to expand its mining operations into an area known as the "Roaring Creek Basin." Occidental has estimated that two and one- half million tons of phosphate are available to be mined in the area with a market value of $25.00 per ton. The company's present timetable would be to commence mining operations in the Roaring Creek Basin by midsummer, 1980. The mining operations would require dredging and filling activities. 1/ The Roaring Creek Basin is a small portion of the Suwannee River Basin. The area of Occidental's mining operation is fairly unique within the Suwannee River Basin. It has been characterized as a relatively high, flat plateau region. The Suwannee River flows in this area through a limestone channel, which is a cut in an older, broader riverbed or flood plane. Roaring Creek and other tributaries of the Suwannee River in the area flow through incisions which have been cut into the plateau area. The incisions become fairly steep in lower areas of the tributaries in close proximity to the Suwannee River. In the upper areas, the incisions are not particularly steep. Limestone beds underlie the area. Sandy clay beds which interbed with the limestone formations lie on top of the limestone beds and are covered by surficial sand beds. The surficial sands are relatively permeable, while the sandy clay beds are relatively less permeable. Rainfall in the area, therefore, typically permeates through the surficial sands and forms an aquifer above the sandy clay layers. This aquifer provides additional water to streams flowing through incisions which have cut into the sandy clay layers. Sources of water for such tributaries are rainfall and the aquifer above the sandy clay layers. There are lower aquifers which could serve as potential sources of water in the tributaries but do not because geologic conditions are not sufficient to force these waters to the surface. 2/ Viewed as a single stream, Roaring Creek has its initial source at a "bayhead" or "cypress swamp" which is located approximately four and one-half to five miles upgradient from the Suwannee River. Prior to the excavation of a channel which occurred sometime during the early 1960's, water flowed from the bayhead through a small incision which does not cut through the surficial sand layers until it reaches a point approximately 2.5 miles upgradient from the Suwannee River. An excavation has been cut through the original meandering streambed from the bayhead to approximately the point where the creekbed cuts into the lower strata. In various places, water from the natural bed flows into the excavation, while in other places, water in the original streambed has been cut off from the excavation by debris. During periods of heavy rainfall, waters in the bayhead rise and flow through the original streambed and the excavated channel to the lower areas of Roaring Creek. The bayhead collects rainwater from surrounding areas and drains fairly slowly in response to rainfall. During dry periods, water does not flow from the bayhead to the lower areas of the creek; however, normally there will be standing water in portions of the original streambed and in portions of the excavation even during drier times. The evidence offered in this proceeding would not support a finding as to the portion of time that water flows all of the way from the bayhead to the lower regions of Roaring Creek. Rainfall is the only source of water for the bayhead and the upper area of Roaring Creek, and the upper area contains water flows throughout its length solely in response to the rainfall. 3/ At a point approximately 2.5 miles upgradient from the Suwannee River, the incision or channel cut by Roaring Creek extends down into the sandy clay layers below the surficial sands. At that point, ground water, which is easily transmitted through the surficial clays, forms an aquifer above the sandy clay layers and seeps rather constantly into Roaring Creek. The point is a short distance upgradient from a road known as "Burned Bridge Road". Roaring Creek flows during all but the very driest periods from that point until its waters reach the Suwannee River. This point, which has been called the "point of intermittency", was placed at slightly different locations by various witnesses, depending upon the sort of analysis that was used. The conclusion that has been found most credible is that presented by Phillip E. LaMoreaux. Dr. LaMoreaux found the point of intermittency to be a short distance upgradient from Burned Bridge Road, approximately 2.46 miles from the mouth of Roaring Creek at the Suwannee River. The point is depicted with precision on Occidental Exhibit 19A. The UTM coordinants of the point are 3367025N336650E. 4/ Downstream from the point of intermittency, Roaring Creek cuts deeper and deeper into the sandy clay strata. It receives waters from several tributaries and form seepage of ground water which occurs throughout this lower portion of Roaring Creek, ultimately cuts into the limestone beds and earns its name as it forms two waterfalls near its mouth at the Suwannee River. 5/ Within and immediately adjacent to the streambed upgradient from the point of intermittency, the dominant vegetation is vegetation which is included in DER's list of freshwater submerged land indicator species. Rules of the Department of Environmental Regulation, Section 17-4.02(17), Florida Administrative Code. The predominant vegetational species are pond cypress (Taxodium Ascendens) and black gum trees (Nyssa Biflora). Within the streambed itself, there are no upland indicator species. Within the excavated channel that has been cut through the natural streambed above the point of intermittency, the predominant vegetation is Maiden Cane (Panicum Hemitomon). Within the bayhead or cypress swamp which is circled on DER Exhibit 8, and is designated with the initials "JK", the dominant vegetation is pond cypress and black gum. The dominance of wetland indicator species which occurs within and directly adjacent to the streambed and the excavated channel does not extend laterally to any great extent. While wetland indicator species will occur sporadically outward from the channels, upland indicator species begin to predominate in all but the areas immediately adjacent to the channels. This reflects the fact that the upper portions of Roaring Creek are in a high upland plateau region. Any effort to determine dominant vegetation outward from the confines of the stream channels would result in a bias in favor of upland species. Within the streambed, there are no small cypress seedlings. This reflects that the streambed has not been dry for any prolonged period of time so as to permit the germination of cypress trees. There are also no hardwood or upland indicator species within the streambed, which reinforces the conclusion that the streambed even above the point of intermittency does not remain dry for long periods of time. 6/ There are several Roaring Creek tributaries where the extent of DER's jurisdiction is at issue. One tributary flows not Roaring Creek from the south and meets the creek at a point upgradient from the point designated "RO-1" on DER Exhibit 8 and on Occidental Exhibit 8. This tributary is outlined with black lines on DER Exhibit 8 and with red lines on Occidental Exhibit 8. The parties agree that DER has jurisdiction over it. A tributary of this tributary is bordered in red on DER Exhibit 8 and in yellow in Occidental Exhibit 8. Very little testimony was elicited with respect to this tributary of the Roaring Creek tributary. It appears that it flows only in response to rainfall events, but the evidence is insufficient to establish whether it normally contains contiguous areas of standing water. Another tributary over which there is a dispute flows into Roaring Creek from the northwest and meets the creek at a point almost halfway between the points "RO-1" and "RO-2", as depicted on DER Exhibit 8 and Occidental Exhibit 8. A portion of this tributary is outlined in black and a portion in green on DER Exhibit 8. Only a portion of it is outlined on Occidental Exhibit The portion of it outlined on Occidental Exhibit 8, and in black on DER Exhibit 8, is below the point of intermittency. The portion outlined in green on DER Exhibit 8 is above the point of intermittency. There is an identifiable streambed above the point of intermittency which connects several cypress swamps. Wetland indicator species (pond cypress and black gum) constitute the dominant vegetation within the cypress swamps and within and directly adjacent to the identifiable streambed. The portion above the point of intermittency flows only in response to rainfall. The evidence would not support any finding with respect to whether it normally contains contiguous areas of standing water. The final testimony over which jurisdiction is disputed enters Roaring Creek from the south, just upgradient from the point designated "RO-4" on DER Exhibit 8 and Occidental Exhibit 8. This tributary is outlined in red on DER Exhibit 8 and in yellow in Occidental Exhibit 8. An identifiable streambed connects the cypress swamp at the head of this tributary with the upper portion of the Roaring Creek channel. Wetland indicator species (pond cypress and black gum) predominate within and directly adjacent to the channel, and within the cypress swamp. It appears that water flows from the cypress swamp to the upper channel of Roaring Creek only in response to rainfall. The evidence would not support any finding as to whether the cypress swamp and streambed of this tributary normally contain contiguous areas of standing water. 7/
Recommendation Upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED: That a final order be entered by the Department of Environmental Regulation finding that the Department has jurisdiction over those portions of Roaring Creek described in Paragraph 5 of the Conclusions of Law set out herein. DONE and ENTERED this 23rd day of May, 1980, at Tallahassee, Florida. G. STEVEN PFEIFFER, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 23rd day of May, 1980.
Findings Of Fact Background Respondent Telese is the owner and developer of Egret Woods Subdivision on real property contiguous to state waters in Pinellas County, Florida. The property is near the incorporated areas of Indian Shores and Largo. A residential subdivision borders the project locale to the east, and tidal mangrove swamps fringe the property to the west. An intracoastal connecting waterway known as the "Narrows" lies to the west of the swamps. These state waters connect Boca Ceiga Bay and Clearwater Harbor. The proposed subdivision area is an upland strip between the existing subdivision and the tidal swamp adjacent to the "Narrows". The uplands are predominantly vegetated by live oak, saw palmettos and slash pines. In order to develop the property, and to reconfigure lots from a previously platted subdivision, Respondent Telese applied for a permit from DER to fill 0.12 acres of DER jurisdictional wetlands located at the development site. The application for the permit represents that 340 cubic yards of clean, non-deleterious sandy loam is needed to fill disturbed high marsh areas and other low areas on the proposed lots. Respondent Telese has also requested permission to install culverts in the two conveyance/mosquito ditches that run through the lots before they reach their discharge points outside of the proposed lot lines. The Petitioners are owners of single-family homes within the subdivision to the east known as Whispering Pines Forest, 5th Addition. These property owners filed a Petition in which they disputed the appropriateness of the Notice of Intent to Issue filed by DER on August 21, 1990. In support of their position, the Petitioners identified a number of areas of controversy they contend should cause DER to reverse its preliminary decision to grant the "dredge and fill" permit on this project. Elimination of Natural Drainage The first area of controversy is the Petitioners' contention that their interests are substantially effected by the elimination of natural drainage from their subdivision into the uplands referred to as Egret Woods Subdivision. The entire area was owned by the same developer prior to the creation of Whispering Pines Forest 5th Addition. Essentially, the Petitioners allege that a subservient estate was created on these adjacent lands for their surface water drainage purposes which the proposed development eliminates. A review of the Notice of Intent to Issue reveals that culverts are to be placed in two of the open conveyance ditches currently transporting surface water runoff from Whispering Pines Forest 5th Addition through the uplands of Egret Woods into the wetlands. While this proposed change in the means of conveyance of the surface water may not affect the volume of water conveyed, it could adversely effect the quality of the water at the discharge points into the wetlands. At hearing, the Petitioners were unable to clearly articulate their concerns about this water quality issue. However, it is intricately interwoven into the surface water management issues. The water quality concern was obliquely referred to in the Biological and Water Quality Assessment Report where DER's application appraiser commented that the proposed conservation easements and the mitigation plantings, which replace the high marsh removed for lot reconfiguration, are sufficient to offset the potential adverse impacts of the requested fill and culvert changes to the existing water quality at the project site. Although this particular water quality issue was properly addressed by DER in its review of the permit application, it was not clearly set forth in the Notice of Intent to Issue. There is no way for a person whose substantial interests are affected by the proposed permitting decision to determine that DER had considered mitigation measures to prevent this adverse effect. A decrease in surface water quality would have been caused by the marsh elimination and the placement of culverts if the marsh had not been replanted, and other mitigative measures had not occurred at the locale. The Petitioners properly requested a formal administrative hearing to address surface water management issues as DER's consideration of the matter was not made clear to them in the Notice of Intent to Issue. The written report that discusses water quality as it relates to the mitigation plan was provided to Petitioner's post-hearing, after a copy of the written appraisal was sent to the Hearing Officer and all parties by DER. Planned Roadway The second area of controversy is the Petitioner's concern about the effects of the planned roadway on their properties. As the planned roadway involves the county, it is not a matter considered in the dredge and fill permit. Neither DER nor the Hearing Officer has subject matter jurisdiction. The Petitioners did not pursue this area of controversy or the road location at hearing based upon the Hearing Officer's ruling that it was not relevant to this permit review. High Water Mark and the Setting of the DER Jurisdictional Line The third area of controversy raised by Petitioners involves their collective concern about a variance in the height of the Mean High Water Line on the property on different documents presented to different agencies. The current survey for DER completed by the surveyor shows the Mean High Water Line at 1.16, while the survey submitted to Pinellas County in 1981 from the same surveyor reads the Mean High Water Line at 1.25. This was explained at hearing by the surveyor. It was his opinion as a professional surveyor that there is no basic difference between these two mean high water lines. Since the survey to the county in 1981, the Mean High Water Line has varied between 3 - 3 1/2 feet in some areas. The same methodology and simple mathematical formula was used by him during the two different surveys which were about eight years apart. The difference in the two surveys is within the tolerance level accepted within the industry and needs no further reconciliation. As a correlative issue, Petitioners raise a concern about the change in DER's jurisdictional line on various documents involving this same site over a number of years. DER's jurisdictional lines have changed since the "Hendersons Wetland Act" enacted on October 1, 1984. The jurisdictional line as depicted on this permit application was established by dominant plant species as defined in Rule 17-301.400, Florida Administrative Code, just prior to the application submission. This was the correct way to determine jurisdiction on the property at this particular point in time. Although the mean high water line may have been determinative of DER's jurisdiction on earlier permits, only the current law applies to the facts of this case. DER reviewed the jurisdictional lines as depicted on the property by Respondent Telese's consultant and found them to be properly placed during the processing of the permit application. Historical DER jurisdictional lines and permit reviews are irrelevant to this permit review as it is based upon the agency's current rules the applicable statutory criteria, and current site conditions. Fill Calculations The fourth area of controversy involves the Respondent's request to place fill on the site. When Petitioners used an engineer's scale to measure the areas to be filled on the permit drawings, their volume calculations reveal that more fill will be needed than represented on the permit application. Petitioners are concerned that this error could cause DER to approve a permit which does not accurately depict site conditions. The actual fill calculations were done by the professional engineer with a computer model based upon average elevations, depth and area. In his professional engineering opinion, his calculations were accurate, which was given great weight by the Hearing Officer. The drawings used by the Petitioners to calculate the required fill for the area were pictorial communications of what the Respondent Telese intended to accomplish at the site. These drawings were designed for descriptive purposes only and were not scaled to the extent that they could be accurately used for fill calculations in the manner applied by Petitioners. The computer modeling used by the professional engineer was the more prudent approach to the on-site fill requirements. De Novo Permit Review Although the wetlands resource permit requested by Respondent Telese is commonly referred to as a "dredge and fill" permit, there is no dredging associated with the project. The proposed placement of fill in the high marsh area of tidal wetlands on the property and the culvert placement requires construction activity in Class III Waters. Water quality impacts to the area will be a short term problem as water turbidity should take place only during construction. Specific conditions regarding construction techniques have been placed in the permit as permit conditions to minimize the impacts. There is no factual dispute as to whether the proposed conservation easement, the replacement and enlargement of the high marsh in another location, the removal of exotics such as Brazilian Pepper trees, and the planting of black mangroves will sufficiently mitigate the adverse impacts on water quality and the public interests at the proposed development. Without the replacement of the disturbed high marsh with high marsh plantings at a 1.91:1 ratio, the enhancement of the property through exotic removal, and the conservation easements at a 132:1 ratio, the Respondent Telese is unable to provide reasonable assurances that the project is not contrary to the public interest under the statutory criteria established in Section 403.918, Florida Statutes. The proposed project will not adversely affect the public health, safety, or welfare or the property of others. The flooding anticipated by the Petitioners is speculative, and has not been directly related to the fill placement and the culverts in the two conveyance/mosquito ditches. Conservation of fish and wildlife and their habitats, will not be adversely affected due to the high marsh replacement and the fact that the area provided only marginal wetland habitat prior to the permit application due to the invasion of exotics at the site. Any impact from the proposed project on this public interest criterion is offset by the mitigation plan. The project will not adversely affect fishing or recreational values or marine productivity in the vicinity of the project. The proposed plantings of black mangroves and the removal of exotics, along with the new high marsh swamp should enhance the productivity of the area. No future projects of a similar nature can be developed at this locale due to the conservation easements the Respondent Telese has consented to provide over the remaining undeveloped property owned by him in the area. These easements will allow the Department to limit and control activities that may be undertaken in these tidal waters to prevent degradation of the site from an environmental standpoint. The mitigation planting schedule provides reasonable assurances that water quality standards will not be violated in the area as a result of culvert placement in the two conveyance/mosquito ditches that transport surface water to Class III waters of the state. Balancing of Interests In the "dredge and fill" permit application appraisal, site review, and Notice of Intent to Issue, DER considered and balanced all of the required statutory criteria to determine that the project is not contrary to the public interest or applicable water quality standards. Area of Controversy All of the areas of controversy raised by the Petitioners which are within the Division of Administrative Hearings' jurisdiction, have been sufficiently met by the reasonable assurances of Respondent Telese and the permit conditions required by DER. Based upon the evidence presented at hearing, it is concluded that the harms anticipated by Petitioners will not occur. Recommendation Regarding the Assessment of Attorneys Fees and Costs Petitioners did not participate in this proceeding for an improper purpose. The Notice of Intent to Issue was vague as to how interests were balanced and how the mitigation would offset the adverse impacts that concerned Petitioners. The petition was filed and prosecuted in good faith and addressed legitimate concerns of concerned citizenry who reside on adjacent lands.
Recommendation Based upon the foregoing, it is recommended: That a Final Order be entered approving Respondent's Telese's dredge and fill permit number 521715273, pursuant to the Notice of Intent to Issue filed August 21, 1990. That Petitioners should not be assessed attorney fees and costs as they did not participate in these proceedings for an improper purpose.

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.
Findings Of Fact On or about May 3, 1978, the petitioner filed with the respondent an application for dredge and fill permits and for a water quality certificate to allow petitioner to complete a planned residential community on and adjacent to Marco Island, Florida. The application encompasses approximately 17,000 acres of petitioner's property, and hundreds of thousands of dollars were expended by petitioner in preparing the application. On November 28, 1979, respondent issued a notice of "intent to deny" the permit application. Among the grounds for denial cited in the nine page "intent to deny" are that the petitioner ". . .has not provided the Department with affirmative reasonable assurance, as required by Subsection 17-4.28(3), Florida Administrative Code, that the immediate and the long-term impacts of this project will not violate State Water Quality Standards." Similar language concerning assurance of water quality standards appears throughout the "intent to deny," as does the Department's assertion of dredge and fill permitting jurisdiction over the proposed development areas. Specific subsections and paragraphs of regulatory rules concerning jurisdiction are not identified in the Department's notice of "intent to deny." The respondent's "intent to deny" is the subject of pending administrative proceedings between these same parties in Division of Administrative Hearings Case Nos. 79-2471 and 80-683. In those proceedings, the petitioner is contesting, inter alia, the Department's application of the rules under challenge herein. By affidavit, the respondent's Chief of the Bureau of Standard Permitting, testified as follows: "I am personally aware that dredge and fill activities often result in violations of water quality standards, result in adverse impacts to and create potentially harmful conditions for animal and plant life, result in the alteration of the chemical, physical and biological integrity of waters, and result in the emission of water contaminants."
