The Issue The issues to be decided in this case are whether Respondent is liable for the violations charged in the NOV, whether Respondent should pay the penalties assessed in the NOV, and whether Respondent should be required to take the corrective actions demanded in the NOV.
Findings Of Fact On August 7, 2014, Petitioner issued the NOV, charging Respondent with failure to maintain its stormwater facility in compliance with its permit and state law. Respondent filed an answer and request for a hearing. The matter was referred to the Division of Administrative Hearings. Petitioner Department of Environmental Protection (“Department”) is the state agency having powers and duties related to the regulation of stormwater facilities. Respondent Classic Homebuilders Incorporated is a Florida corporation and holds a General Stormwater Permit issued by the Department for the construction and operation of a stormwater facility at 5100 Terra Lake Circle, Pensacola, Florida. On April 9, 2013, Department staff inspected Respondent’s stormwater facility and determined that the ponds do not percolate within 72 hours as required by the permit. On July 23, 2014, Department staff inspected the facility again and determined that the percolation problem had not been corrected. Debris and silt were observed in the stormwater facility. Respondent has not submitted an “as-built” certification. The Department incurred $500 in expenses associated with its investigation of this matter. That is a reasonable amount.
Findings Of Fact In 1984, the South Florida Water Management District (SFWMD) issued surface water management permit number 48-00201-5 for a 515 acre project, Isleworth Golf and Country Club, located in southwest Orange County. The permit was issued to the developer, Isleworth Partners. Sometime after the permit was issued and the system was constructed, nitrate concentrations were detected in holding ponds BE-15 and 16. District staff speculated that the shallow ground water table was contaminated with residual nitrogen left from nutrient applications to a citrus grove previously on the site. They were concerned that the high nitrate ground water was seeping into the storm water storage ponds and would eventually be discharged into adjoining Lake Bessie, thereby affecting the water quality of the lake. Lake Bessie, along with other lakes in the region, was also experiencing rising levels. On March 24, 1988, Isleworth Partners submitted to the SFWMD its application number 03248-G, to modify the existing surface water management permit, to help prevent the water quality problems from occurring in Lake Bessie, as described above, and to ameliorate and mitigate against increased lake levels in Lake Bessie. It was not intended to provide flood protection for Lake Bessie. The solution proposed in the modification request, as well as in water use permit applications processed at the same time, was to retain substantially more water in storage ponds BE-15 and 16, and to recycle some of the water from those ponds for use in irrigating the golf course. There were no objections to the water use modifications which were processed with the surface water management permit modification, and the water use modifications were approved by the SFWMD governing board in June 1988. As they affect ponds BE-15 and 16, the water use modifications include pumping the ponds down to a new control level of 97 feet NGVD and using that water to irrigate the golf course. This process has already been implemented with beneficial results: the nitrate concentrations in the ponds have been reduced. The surface water management modification which is the subject of the application at issue is to raise the weir structure from 101.6 to 103 feet NGVD in pond BE-15 to provide complete retention of a 10 year/24 hour storm event without discharge to Lake Bessie from the pond. The under drain system at Pond BE-15 will also be plugged to prevent the existing permitted bleed down of the pond waters into Lake Bessie. This structural modification involves simple construction work and can be completed in one or two days. Ponds BE-15 and 16 are currently connected by an equalizer pipe, and will remain so. Under the modifications the ponds will be maintained (control elevation) at 97 feet NGVD through the use of existing permitted pumps. The maximum elevation of the ponds will be raised from 101.6 feet to 103 feet NGVD by the alteration of the weir. This means the waters in the ponds would have to top 103 feet to overflow and discharge, by way of an existing pipe, to the swales along Lake Bessie and thence into the lake. A 10 year/24 hour storm event is the amount of rainfall that will statistically occur in a 24-hour period once every ten years, or ten times in a 100-year period. The amount of rainfall in a 10 year/24 hour storm event is roughly seven and a half inches. The modification proposed by Isleworth Partners is intended to retain the runoff from that storm. Currently, under the system as permitted, only the first inch of runoff must be retained. This is about 2.4 inches of rainfall or approximately a 3-year/1-hour storm event. Substantially more water will be retained in Ponds BE-15 and 16 under the proposed modification. The staff of SFWMD recommended that the application be granted, with twelve standard limiting conditions and eight special conditions, including the following: * * * The permittee shall be responsible for the correction of any water quality problems that result from the construction or operation of the surface water management system. The district reserves the right to require that water quality treatment methods be incorporated into the drainage system if such measures are shown to be necessary. * * * (Isleworth Exhibit #3, p. 6) John Robertson, Donald Greer and Robert Londeree reside on Lake Bessie. John Robertson and Donald Greer are members and officers of a nonprofit corporation, the Petitioner in this case, Friends of the Lakes, Inc. These residents are concerned that the level of Lake Bessie has risen in the last few years and that it is becoming polluted. Long standing docks which had been primarily dry are now frequently under water. The residents have observed milky or greenish yellow water discharging from pipes from the Isleworth development. These residents, who are not parties to the proceeding, concede that, if the modification works as intended, the system will be improved and the impact to Lake Bessie Will be lessened. Petitioner, Friends of the Lakes, Inc., questions the reliability of the pumping system to maintain the 97.0 foot control elevation. If the ponds are maintained at a control level of 97.0 feet, the 10 year/24 hour storm water will be retained. If, however, through a series of smaller events, the level is higher than 97.0 feet, less capacity will exist, and the water will discharge sooner to Lake Bessie. The current permitted pump operates at 375 gallons a minute. Depending on whether the pump is operated continuously or part-time, it would take from four to twenty days to pump down the pond from a maximum 103 feet to the 97 foot level. The District found the pumping system to be acceptable at Isleworth because the development has a full-time maintenance staff of 35 people, of whom three work on the pumping system. A maintenance supervisor checks the pumps daily, and the developer has an agreement with a pump company to replace the pump, if needed, within four to six hours. The system is considered reliable and the increased pond holding capacity will insure that more water will be retained than under the existing permitted system. Stephen Miller is the professional engineer whose firm prepared the application for modification and the original application for the surface water management permit. He is aware of some changes in the project as constructed which differ from his design for the original system. These changes relate specifically to grading on the golf course and not, as suggested by Petitioner, to the operation of ponds BE-15 and 16. Stephen Miller believes that the modifications will do exactly what they are proposed to do. The application for the modifications took into account the existing conditions which differ from the permitted construction plans. Ronald R. Potts testified for Petitioner as an expert in geology and surface and ground water hydrology. He agrees that the application for modification meets all requirements of the SFWMD with the exception of a single standard condition: * * * 3. The permittee shall comply with all applicable local subdivision regulations and other local requirements. In addition, the permittee shall obtain all necessary federal, state, local and special district authorizations prior to the start of any construction or alteration of works authorized by this permit (Isleworth Exhibit #3, P. 6.) The district staff report recommending approval for the modification request was sent to Orange County for its review and comment. Orange County made no objections. Within Orange County it is the engineering department which is responsible for the implementation and interpretation of the Orange County subdivision regulations as they apply to storm water management. The SFWMD does not attempt to enforce other agencies' requirements. The Orange County Engineer, George Cole, determined that neither section 10.1.2 nor section 10.4.4(D) of the Orange County Subdivision Regulations were applicable to the modification proposed by Isleworth. Section 10.1.2 requires that recharge to the Floridan Aquifer, where soils are compatible, shall be accomplished by providing for retention of the total run off generated by a 25 year frequency, 24 hour duration storm event from the developed site. Section 10.4.4(D) of the Orange County Subdivision Regulations requires that a pond design detain a 100 year storm event when discharge into a lake without a positive outfall is proposed. When the County first approved Isleworth's Planned Development, it set a specific requirement that the storm water management system retain the first inch of runoff and detain the difference between pre-development and post- development discharge for a 25 year/24 hour storm. "Retention" of storm water means that the water must be held on site and disposed of by some means other than discharge. "Detention" requires only that water be held back for a period of time before discharge. The Isleworth property is not located in a prime recharge area, as under its soils is a highly impermeable lens, commonly called "hardpan." Lake Bessie has a positive outfall, a pipe connecting Lake Bessie with nearby Lake Down. Although the pipe was plugged with debris for a period of years, it has been cleaned out and the potential exists for outfall from Lake Bessie in flood conditions. The County's 100 year/24 hour detention requirement would still allow the ponds to discharge more water to Lake Bessie than the proposed 10 year/24 hour retention design, and is, therefore, less restrictive. Lake Bessie presently is one of Florida's most pristine lakes with crystal clear water that is ideal for recreational purposes. The natural dynamic state of lakes is that over a period of time they evolve from oligotrophic, with clear water and a balanced system; to mesotrophic, with less water clarity, more nutrients, increased algae and less desirability for human use; to a eutrophic state, with even less clarity, choking vegetation, less fish and less pleasing appearance and utility. This occurs in a natural state as lakes fill in with decaying matter from the shore. Petitioner claims that discharge from Isleworth will hasten the death of the lake. Phillip Sacco testified for the Petitioner as an expert biologist and limnologist (one who studies fresh bodies of water). He performed a modeling analysis to determine the amount of phosphorus being discharged into Lake Bessie and he opined that the Isleworth development will cause Lake Bessie to change to a eutrophic state. A significant component of his analysis was his assumption that 920 acre-feet of water would be discharged into Lake Bessie as a result of the modification. (transcript pp. 557-558). The 920 acre feet is actually the total amount of water which enters Lake Bessie from the entire Lake Bessie basin, not just from the Isleworth property, and includes both surface water (2%) and ground water (98%). The analysis is discredited by the false assumption. Mr. Sacco also theorized that the interaction of nitrogen and phosphorus precipitated by the change in land use occasioned by the Isleworth development would produce deleterious effects on Lake Bessie's water quality: "Nitrogen is the dynamite; phosphorus is the fuse and the land use change of Isleworth is the match." The permit modification application at issue does not relate to a land use change. The change from orange groves to residential development occurred years ago and has already been permitted. In fact, the land change providing the ignition in Mr. Sacco's vivid metaphor is just as likely in the even earlier cultivation of the groves and use of nutrients in their production. The single result of the modification at issue will be less water being discharged into Lake Bessie than is currently permitted from the system, thus conserving the water quality present in the lake. The residents who testified are not parties to this proceeding. Although two of them established they are members and officers of Friends of the Lake, Inc., no evidence was produced regarding the corporation, its legal existence or purpose.
Recommendation Based on the above it is hereby RECOMMENDED: that a final order be issued granting the application for permit modification, and denying Isleworth Partners' request for costs and attorney's fees.

The Issue The issue to be resolved in this proceeding concerns whether an on-site sewage disposal system ("OSDS") construction permit should be issued to the Petitioner based upon the question of whether the property lies within the ten- year flood elevation of the Suwannee River, and if so, whether an appropriate system can be designed which will remove the system an adequate distance above the ten-year flood elevation level and thus comply with Rule 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner, Allyn B. Giffin, wishes to construct a vacation-type, part-time residence on his lot lying in Dixie County, Florida, in the vicinity of the Suwannee River. The subject proposed disposal system site lies at the Suwannee River Water Management District's river mile no. 50 and the ten-year flood elevation for that site and river mile is 21 feet above mean sea level ("MSL"). The property also lies within the "regulatory floodway" of the Suwannee River, as regulated by the Suwannee River Water Management District, and may require a "works of the district" permit. The elevation of the surface grade at the subject site is approximately 17 feet, 7 inches above MSL, as shown by the survey of Herbert Raker, a certified land surveyor. Because the property lies within the regulatory floodway of the Suwannee River, the pertinent rule requires that an engineer certify that any mounding of the system to raise it above the flood plain and the regulatory floodway level will not cause any alteration in the base flood level in that regulatory floodway of the Suwannee River. Aside from being within the regulatory floodway and beneath the ten- year flood elevation, the property is amenable to the type of subsurface septic tank and drain-field system proposed. The water table at the time of the site evaluation performed by Mr. Fross, of the Department was 72 inches below the existing surface grade. Based upon mottling in the soil, the estimated wet season water table was 42 to 48 inches below surface grade. Since the surface grade elevation at the proposed site is 17 feet, 7 inches, and the ten-year flood elevation is only 21 feet, it was shown to be quite feasible to elevate the septic tank system in a filled mound and mound pad, such that the entire system could be raised the required regulatory distance above the ten-year flood elevation level. Mr. Ted Biddy was accepted as an expert witness in the field of civil engineering with emphasis on sanitary system engineering. He testified on behalf of the Petitioner. Mr. Biddy has designed a sewage disposal system for the Petitioner, which design is admitted into evidence, which is designed to be constructed and to operate above the ten-year flood plain elevation found above. The system is called a "mounded balancing system". It will consist of a raised earthen pad with a raised mound on top of that pad containing the septic tank and drain-field system at an elevation sufficient to maintain the required regulatory differential between the bottom elevation of the drain-field trenches and the ten-year flood elevation. This system was established by Mr. Biddy's testimony to avoid any deleterious effect on public health and environmental safety which might be posed by the sewage effluent entering the system if it were placed below the existing surface grade of the lot in question. The water table elevation is at a minimum of 42 inches below the surface grade of the lot; and if the proposed system were raised above the ten- year flood elevation, the bottom grade of the drain-field trenches would be at least five feet above the surface grade elevation of the lot at the proposed installation site, plus an additional 42 inches above the wet season water table level established by the testimony of Mr. Fross, who did the site evaluation for the Department. It was thus established that such a mounded system will meet all of the parameters contained in Chapter 10D-6 and, specifically, Rules 10D- 6.044-049, Florida Administrative Code, the rules as they applied at the time of application and hearing. Dr. Richard Hunter, testifying as an expert witness for the Department, had not seen this design until the day of the hearing. Upon reviewing it, he agreed that if such a system were installed on the lot in question, it would meet all of HRS regulatory parameters and would be permittable, at least for a two-bedroom dwelling. Mr. Biddy further established that even with a three-bedroom dwelling, as originally proposed by the Petitioner, because it would only have intermittent, occasional use as a vacation retreat, the sewage loading would be substantially less than would the loading from a normal three-bedroom, full-time residence. It is also true, as found above, that the property is in the regulatory floodway of the Suwannee River. Because of this, the Department's rule requires that an engineer certify that installation of such a mounded system will not raise the base flood level of the so-called "100 year flood". This is a balancing system, as described by Mr. Biddy, which involves the removal of approximately 877 cubic yards of fill material from the site or that portion of the site which lies within the regulatory floodway. This is an amount exactly equal to the required amount of fill to construct the mounded system, as proposed. Because of this, the addition of the 877 cubic yards of fill material for the mounded system will not cause additional displacement and resulting raising of the base flood level. Thus, the Department's rule in this regard will be complied with. This is because the fill material will replace an equal amount of material excavated from the lot in that portion below the regulatory floodway level, which excavated material will be removed from the regulatory floodway entirely, thus resulting in no net gain of fill material within the regulatory floodway and, therefore, no additional displacement or elevating of the base flood level. In summary, it has been demonstrated that the addition of the mounded system, as proposed by the Petitioner through the testimony of Mr. Biddy, will not pose any environmental hazards or any potential harm to public health and safety and will result in the sewage disposal system proposed being installed at an elevation properly above the ten-year flood elevation of 21 feet above MSL. The Department has interpreted the Executive Order of the Governor, 90-14, purporting to prohibit such systems beneath the 10-year flood elevation of the Suwannee River as requiring strict prohibition of such systems in those circumstances when it carries out its enforcement of the requirements of Rule 10D-6.047(6), Florida Administrative Code, the rule applicable to this permit application, hearing and circumstances. Further, the Petitioner has agreed to limit the size of his dwelling to a two-bedroom dwelling instead of a three- bedroom dwelling.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be issued by the Department of Health and Rehabilitative Services granting a permit to the Petitioner, Allyn B. Giffin, authorizing the installation of an on-site sewage disposal system in the manner and under the conditions enumerated in the above Findings of Fact and Conclusions of Law.

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 central issue in this case is whether the application for a surface water management permit (permit no. 4-009-0077AM) filed by the Respondent, David A. Smith (Applicant), should be approved.
Findings Of Fact Based upon the prehearing stipulations of the parties, the testimony of the witnesses, and the documentary evidence received at the hearing, the following findings of fact are made: The Applicant is the owner of the subject property. The Applicant filed an application for a permit to construct a stormwater management system which was proposed to serve a residential and golf course development to be known as Sabal Hammocks. The site of the proposed project is approximately 720 acres in size and is located in township 24 south, sections 28, 29, 30, 32, 33, and 34, range 35 east, Brevard County, Florida. The entire project site for the Sabal Hammocks development is located within the boundaries of the St. Johns River Water Management District. To the west of the project site is an 140 acre public park that treats its own stormwater and releases pre-treated stormwater during some storm events into the canals on the Sabal Hammocks site. The Applicant's site is located adjacent to Lake Poinsett and prior uses of the land have included cattle grazing and the cultivation of rye and oats. The Applicant filed his application for the stormwater management permit (permit NO. 4-009-0077AM) on December 22, 1989. That application was deemed complete by the District on June 19, 1990. The District issued a notice of its intended action to approve the permit application on June 28, 1990. Save timely filed a petition challenging the proposed action. By law the District is the appropriate agency charged with the responsibility of reviewing applications for stormwater management permits within the subject area. Save is an association of individual persons and representatives from groups who utilize the waters of Lake Poinsett and its surrounding areas for recreational and business purposes. The receiving waters for stormwater discharge from the proposed Sabal Hammocks development will be Lake Poinsett. That water body is classified as Class III waters. Currently, a dike system exists along the southern boundary of the subject property. That dike system separates the internal grazing lands of the parcel from the lower marsh and flooded areas external to the dike. A series of ditches cross the parcel to drain the interior areas. Two agricultural discharge pumps are currently in use at the site. The operation of those pumps has been authorized pursuant to a consent order approved by the District's governing board on December 13, 1990. The dike system on the subject site has been in place since the 1970s. The original construction specifications of the dike are unknown. Sometime in the 1980s, several openings or breaches were cut in the dike system. Those breaches were opened pursuant to permits issued by the District and the Department of Environmental Regulation (DER) . The breaches were cut to a sufficient width and depth to allow boats to navigate through to interior areas of the subject property during those times when the water levels outside the dike would allow such entrance. The breaches were not cut to ground level and the original dike remained intact and uncompromised by the breaches. That is, the dike has not failed to impede water movement and the integrity of the dike was not weakened by the breaches. The original outline, dimension of the dike, remained visible despite the breaches. In 1986, the Applicant requested permission from the District staff in order to close or restore the dike breaches. At that time, the District staff advised David Smith that a permit would not be required to restore the dike since such improvements would be considered a maintenance exemption. Subsequently, and in reliance upon the representations made by the District's director,, the Applicant closed the breaches and restored the continuity of the dike system of the subject property. The Applicant's work to close the breaches was performed in an open manner, would have been visible to persons using the adjacent marsh or water areas for recreational purposes, and was completed at least one year prior to the application being filed in this case. Neither the District nor DER has asserted that the work to complete the original dike in the 1970s, nor the breaches completed in the 1980s, nor the restoration of the breaches in 1986 was performed in violation of law. Further, the District had knowledge of the subject activities. Save contends that the restoration of the dike system was contrary to law and that it was not afforded a point of entry to contest the closure of the breaches. Additionally, Save infers that the original construction of the dike system in the early 1970s was without authorization from authorities. Save's contention is that the prior condition of the property, ie. the parcel with breached openings, must be considered the correct pre- development condition of the land. The District, however, considered the pre- development condition of the parcel to be that of a diked impoundment separated from Lake Poinsett. The same assumption was made regarding the pumping of water from the area enclosed by the dike via an existing 36 inch pump which discharges to Bass Lake (and then to Lake Poinsett) and an existing 12 inch pump that discharges into the marsh areas adjacent to the property (between it and Lake Poinsett). The District's consideration of the site and the application at issue was based upon the actual condition of the land as it existed at the time this application was filed. The pre-development peak rate and volume of discharge from the site was calculated based upon the maximum discharge capacity of the two existing pumps (described above). Accordingly, the maximum pre-development rate of discharge from the two existing pumps is in the range of 90-107 cubic feet per second. The pre-development volume of discharge, based upon actual pump records, was calculated as 710 acre-feet for a 25 year, 96 hour storm event. The total areas encompassed by the Applicant's proposal are the 720 acre site where the golf course and residential homes will be located together with 140 acres from an adjacent public park. The runoff entering the stormwater system from that public park will have already been treated in its own stormwater management system. The Applicant's proposed stormwater system will consist of a series of lakes and interconnected swales. This wet detention system will capture the runoff and direct its flow through the series of swales and lakes via culverts. The waters will move laterally from the northwestern portion of the parcel to she southeastern end of the site. From the final collecting pond, she waters will be pumped to Bass Lake and ultimately flow to Lake Poinsett. Wet detention systems generally provide greater pollutant treatment efficiencies than other types of stormwater treatment systems. The maintenance associated with these systems is also considered less intensive than other types of treatment systems. The wet detention system proposed for Sabal Hammocks accomplishes three objectives related to the flow of stormwater. The first objective, the collection of the. stormwater, requires the creation of several lakes or pools into which water is directed and accumulates. The size and dimension of the lakes will allow the volume of accumulated water to be sufficient to allow stormwater treatment. The capacity of the lakes will also provide for a sufficient volume to give adequate flood protection during rainfall events and storms. The second objective, the treatment of the stormwater, requires the creation of a littoral zone within the system. The littoral zone, an area of rooted aquatic plants within the lakes or ponds, provide for the natural removal of nutrients flowing into the system. The plants serve as a filtering system whereby some nutrients are processed. The proposed littoral zone in this project constitutes approximately 37 percent of the detention system surface area and therefore exceeds District size requirements. The depth of the treatment volume for the proposed system will not exceed 18 inches. A third objective accomplished by the creation of the series of lakes is the provision for an area where pollutants flowing into the detention system may settle and through sedimentation be removed from the water moving through the system. The average residence time estimated for runoff entering the Sabal Hammocks detention system is 48 days. The permanent pool volume will, therefore, be sufficient to assure the proposed project exceeds the District's requirements related to residence time. The design and volume of the Sabal Hammocks system will also exceed the District's requirements related to the dynamic pool volumes. In this case the Sabal Hammocks system will provide for approximately 65 acre-feet of runoff. Thus, the proposed system will adequately control and detain the first 1 inch of runoff from the site. The length to width ratio for the proposed lakes, 18:1, exceeds the District's minimum criteria (2:1). The final lake or pond into which the stormwater will flow will be 17 acres and will have 15 acres of planted wetland vegetation. Before waters will be released into Bass Lake, the site's runoff will pass through 3100 linear feet of this final lake before being discharged. The proposed project will eliminate the two agricultural pumps and replace them with one pump station. That station will contain four pumps with a total pumping capacity of 96 cubic feet per second. Under anticipated peak times, the rate of discharge from the proposed single station is estimated to be less than the calculated peak pre-development rate of discharge (90-107 c.f.s.). The estimated peak volume of discharge will also be lower than the pre-development discharge volumes for the comparable storm events. The proposed pump station is designed to be operated on electrical power but will have a backup diesel generator to serve in the event of the interruption of electrical service. Additionally, the pumps within the station will be controlled by a switching device that will activate the pump(s) only at designated times. It is unlikely that all four pumps will activate during normal rainfall events. The Applicant intends to relinquish maintenance responsibilities for the stormwater system including the pump station to Brevard County, Florida. Finished floor elevations for all residential structures to be built within the Sabal Hammocks development will be at a minimum of 18.2 mean sea level. This level is above that for a 100 year flood. The floor elevations will be at least one foot above the 100 year flood elevation even in the event of the dike or pump failure or both. Finished road elevations for the project will be set at 17.5 feet mean sea level. This elevation meets or exceeds the County's requirements regarding the construction of roadways. It is estimated that the Sabal Hammocks system will retain at least 26 percent of all storm events on site. If the lake system is utilized to irrigate the golf course the proposed system could retain 45 percent of all storm events on site. Of the 31.27 acres of wetlands within the proposed site, only 4.73 acres of wetlands will be disturbed by the construction of this project. Some of the wetlands are isolated and presently provide minimal benefits to off-site aquatic and wetland dependent species. No threatened or endangered species are currently utilizing the isolated wetlands. The areas of wetlands which are productive and which will be disturbed by the development will be replaced by new wetlands to be created adjacent to their current location at a lower elevation. The new wetlands should provide improved wetland function since those areas will be planted with a greater diversity of wetland plant species. Additionally, other wetland areas will be enhanced by the removal of invader species and increased hydroperiod in the area. The integrated pesticide management plan for the proposed project will be sufficient with the additional condition chat use of Orthene, Subdue, and Tersan LSR will be authorized when approved insecticides or fungicides have not been effective. In this case, the estimates regarding the water quality for the proposed project were based upon data from studies of multifamily residential projects. Data from single family/ golf course developments was not available. Therefore, based upon the data used, the projected runoff concentrations for this project should over estimate pollutants and are more challenging to the treatment system than what is reasonably expected to occur. In this regard, the overall treatment efficiencies are estimated to be good for all of the parameters of concern with the exception of nitrogen. The projected increase in nitrogen, however, will not adversely impact the receiving water body. The projected average concentration for each constituent which may be discharged is less than the state standard with the exceptions of cadmium and zinc. In this regard, the District's proposed conditions (set forth in the District's exhibits 4 and 9) adequately offset the potential for a violation of state water quality standards. More specifically, the use of copper-based algaecides in the stormwater management system should be prohibited; the use of galvanized metal culverts in the stormwater management system, or as driveway culverts, should be prohibited; and the use of organic fertilizers or soil amendments derived from municipal sludge on the golf course should be prohibited. Additionally, a water quality monitoring plan should be implemented by the Applicant. The monitoring plan mandates the collection of water samples from areas in order to adequately monitor the overall effectiveness of the treatment facility. The source of cadmium is not be expected to be as great as projected since the most common source for such discharge is automobiles. It is unlikely that the golf course use will generate the volume of discharge associated with automobile use that the multifamily data presumed. The projected quality of the discharges from this project should be similar to the ambient water quality in Lake Poinsett. In fact, the post- development pollutant loading rates should be better than the pre-development pollutant loading rates. The discharge from the proposed Sabal Hammocks project will not cause or contribute to a violation of state water quality standards in Lake Poinsett nor will the groundwater discharges violate applicable state groundwater quality standards. The floodways and floodplains, and the levels of flood flows or velocities of adjacent water courses will not be altered by the proposed project so as to adversely impact the off- site storage and conveyance capabilities of the water resource. The proposed project will not result in the flow of adjacent water courses to be decreased to cause adverse impacts. The proposed project will not cause hydrologically-related environmental functions to be adversely impacted The proposed project will not endanger life, health, or property. The proposed project will not adversely affect natural resources, fish and wildlife. The proposed project is consistent with the overall objectives of the District.
Recommendation Based upon the foregoing, it is RECOMMENDED: That the governing board of the St. Johns River Water Management District enter a final order approving the application for permit number 4-009-0077AM with the conditions outlined within the District's exhibits numbered 4, 8, and 9 and as previously stated in the notice of intent.

Findings Of Fact The Navy intends to construct a 160 unit residential housing project at Key West, Florida. This project will be built on a 25.89 acre site that is bordered on the north by Eaton Street and Palm Avenue, on the east by Eisenhower Drive, on the south by Angela Street, and on the west by White Street. As designed, the completed site will have approximately 58 percent pervious area and 42 percent impervious area. In its undeveloped state, storm water runoff for the Peary Court site sheetflows to the north where a concrete containment wall directs the runoff to an existing inlet and storm drain. This existing inlet and drain connects to the City of Key West's drainage system at the corner of Palm Avenue and Eisenhower Drive and eventually discharges into a nearby surface water body known as "Garrison Bight". Runoff capacity that cannot be managed by the City of Key West's drainage system collects and discharges onto Palm Avenue. On September 21, 1992, the Navy submitted its initial permit application to the Department for the issuance of seven Class V storm water injection well permits. The seven injection wells are designed to function as part of a surface water management system. The storm water management system must be permitted by the South Florida Water Management District (SFWMD). The injection wells must be permitted by the Department. The proposed surface water management system for Peary Court was designed to meet SFWMD permitting criteria and will utilize dry detention with filtration through grassy swales and grassy retention ponds for the pretreatment of the project's storm water runoff. The Navy applied to SFWMD for a permit for the proposed surface water management system. The SFWMD tentatively approved the application. Thereafter, a challenge was filed to the proposed agency action, and the matter was referred to the Division of Administrative Hearings and assigned DOAH Case No. 92-6254. A Recommended Order was entered in DOAH Case NO. 92-6254 which recommended that the surface water management system be approved. A Final Order has been entered in DOAH Case 92-6254 by the SFWMD approving the Navy's surface water management system permit for Peary Court. The period for appeals of the Final Order has not expired as of the entry of this Recommended Order. The Department gave notice on December 4, 1992, of its intent to issue the permits to the Navy for not more than seven injection wells to be operated as part of the Peary Court surface water management system. The permit the Department intends to issue contains 16 general conditions and 10 specific conditions. None of the conditions are being challenged by the Navy. Among the specific conditions are the following: This permit is valid only for the specific process and operation indicated in the application. Any changes in these which may result in altered characteristics of the discharge are not permitted without the prior approval of the Department and modification of this permit. The discharge authorized by this permit shall be consistent with the water quality standards set forth in Chapter 17-3, F.A.C. [S]hould conditions in the receiving body warrant, the Permittee may be required by the Department to upgrade, reduce or cease discharge of run-off approved by this permit, and adopt an alternative method of disposal within a reasonable time. The permittee shall establish a periodic maintenance program that assures the integrity of the storm water drainage system to function as designed. "Detention" as that term is used in the context of surface water management systems is the temporary detaining of water on a site prior to eventual offsite discharge. "Retention" is the permanent retaining of water on a site with no offsite discharge. The proposed surface water management system will utilize grassy inlets and swales to direct runoff into four large grassy detention ponds as well as smaller pond areas prior to discharge from the surface water management system. Storm water that does not evaporate or percolate into the ground will be discharged through a v-notch weir discharge structure into Garrison Bight or to ground waters via the proposed injection wells. The detention ponds are connected with one another and act as one system so that the ponds fill and empty at the same rate. The surface water management system for Peary Court is designed so that there will be no offsite discharge during the first inch of a rainfall event. The on-site detention of the first inch of rainfall results in the removal of approximately 90 percent of all pollutants prior to discharge through what is referred to as "first flush". With the exception of one cul-de-sac in the northeast corner of the project near the v-notch weir, all runoff draining into the proposed detention areas will flow through grassy swales and inlets. The proposed grassy inlets and swales will transport runoff to the grassy detention ponds at a rate of one quarter to one half inch per second and thus will provide adequate filtration for the storm water runoff before it gets to the detention pond. The storm water that comes from the cul-de-sac will include storm water from Palm Avenue, which is adjacent to the Peary Court site. This storm water will travel through at least 50 feet through pipe before entering the detention pond and will receive little filtration prior to entering the detention pond. The water from the cul-de-sac will receive some filtration in the detention pond. The system is designed to detain the amount of storm water runoff which would be expected from a twenty-five year, three day storm event. Such a storm event in Key West would be expected to represent roughly a six to seven inch rainfall. The proposed injection wells are Class V, Group 5 storm water drainage wells pursuant to Rule, 17-28.130(1)(e)5, Florida Administrative Code, and meet all pertinent construction standards. The proposed injection wells will be located on the north side of Peary Court. The exact location and number of injection wells to be utilized will be determined by data received from conducting a well capacity test after the installation of the first injection well. The pre-development runoff from Peary Court was 55 cubic feet per second (cfs). Pursuant to SFWMD permitting criteria, the post-development discharge cannot exceed the pre-development discharge. The discharge capacity from the v-notch weir into Garrison Bight is 11 cfs. Consequently, the maximum discharge from the injection wells will be 44 cfs. The proposed location and number of wells are based on conservative estimates. No allowance is made in the surface water management system for naturally occurring evaporation or percolation. Discharges down the proposed injection wells is not continuous and is only expected to occur during rare storm events. The bottom of the detention ponds will be set at elevation 1.0 NGVD. The water inlets for the injection wells will be set at elevation 1.5 NGVD. Because the proposed water inlet for the v-notch weir discharge structure will be set at elevation 1 NGVD, offsite discharge to Garrison Bight will begin through the v-notch weir before any discharge through the injection wells. Discharge of storm water down the proposed injection wells will only occur when water levels in the ponds reach six inches (0.5 NGVD). The proposed wells will be drilled to a depth of ninety feet with grouted steel casing extending down to a depth of sixty feet below land surface. The wells are to be grouted to ensure that there will be no vertical migration along the borehole. Each injection well will have a concrete wellhead with a built in baffle to prevent floating debris, silt or sand from entering the well. The baffle will not prevent contaminants that are suspended in the storm water from being discharged through the injection well. The Navy provided a bedrock assessment and groundwater quality profile by drilling two exploratory boreholes at Peary Court. The subsurface strata underlying Key West consists of distinct horizontal layers of Miami Oolite and Key Largo Limestone. Beneath Peary Court, Miami Oolite extends from ground surface down to between forty-seven and fifty feet below land surface. The Key Largo Limestone extends below the Miami Oolite formation. Key Largo Limestone consists mainly of coral and limestone and is generally more porous and more permeable than Miami Oolite. Miami Oolite consists mainly of small sand like particles cemented together. Both formations can contain clays and lime or silicate muds. The Miami Oolite layer is not considered by the Department to be a "confining layer" as that term is used in the Department's rules determining the classification of wells because of its limited ability to retard the flow of fluids. The injection zone for the proposed injection wells will be between 60 to 90 feet below land surface, which is in the Key Largo Limestone formation. Ground water in the injection zone contains 35,000 to 40,000 milligrams per liter (mg/l) of total dissolved solids (TDS). Ground water in the injection zone is classified under Department rules as G-III because it is ground water having more than 10,000 mg/l TDS. A freshwater lens (the Key West lens) underlies a portion of Key West. The United States Geological Survey (USGS) documented the water quality and approximate size of the lens in 1990 by analyzing water samples taken from shallow monitoring wells. The results were compiled into what is referred to as the McKenzie Report. This thin layer of freshwater, varying in depths from two to ten feet, sits on top of a transition zone between the seawater and freshwater. This transition extends downward to approximately 40 feet below the surface of the land. The freshwater lens does not underlie Peary Court. The Key West lens is classified under Department rules as G-II because it is ground water having less than 10,000 mg/l TDS. The McKenzie Report documents the size of the lens using chloride concentration contours, with 250 mg/l chloride at the center of the lens out to 5,000 mg/l at the edge of the lens. Chloride concentrations of 250 mg/l or less is the standard maximum chloride level for drinking water. The locations of the proposed injection wells are outside of the 5,000 mg/l chloride concentration contour. There is no potable water source in the immediate vicinity of the proposed wells. The proposed injection wells will not be installed through G-II ground water (Key West lens), nor will it inject storm water into G-II ground water. Movement of water in the injection zone will be governed by two forces, pressure gradients and buoyancy factors. The injected water is more buoyant than sea water because it is less dense. Consequently, there will be a tendency for the injected water to move upward. The injected water also moves outward along pressure gradients associated with the Key West lens. The Key West Lens is thicker in the center and thinner towards the sides. Because of this fact, it has varying pressure gradients which is greater toward the center and will cause the injected water to move away from the Key West Lens. It is an established geologic principle that subsurface sedimentary rock formations generally favor lateral movement of water over vertical movement. Because the Key Largo Limestone strata is more porous and more permeable than the Miami Oolite strata and because of the pressure gradients of the Key West Lens, the storm water injected through the injection wells will move laterally away from the Key West Lens and towards Florida Bay. Tidal action will contribute toward the movement of the injected storm water away from the Key West Lens. It is not expected that the injected storm water will reach the Key West lens. When the relative densities of the injected water and the ground water equalize, upward movement of the storm water will cease. Subsurface tidal flows will have a washing machine effect on the discharging storm waters that will enhance the mixing and dispersion of the storm water. The mixing and dispersion of the storm water caused by subsurface tidal flows serve to reduce the buoyancy of the storm water, which retards its upward movement. The Department has relied, in part, on the review by SFWMD of the surface water management system in reaching the conclusion that the storm water discharged through the wells will meet water quality criteria after having moved through the surface water management system. When the Navy first applied for the surface water management system permit, it was believed that Garrison Bight had been designated as an Outstanding Florida Water. Consequently, SFWMD required that the surface water management system be designed to meet discharge criteria applicable to Outstanding Florida Waters. Notwithstanding such design, it can still be expected that minute levels of various contaminants typically found in storm water, such as heavy metals and those contained in pesticides, petroleum products, and animal waste, will remain in the discharged storm water. Saline ground waters contain microorganisms which live off trace amounts of organic material. Highly active zones of microorganisms, such as those found around injection wells, feed on and effectively break down organic compounds, including petroleum constituents, which may be discharged from injection wells. Any heavy metals that may remain in the storm water when it is injected through the injection wells will likely be absorbed onto the minute clay particles present in the Key Largo Limestone and Miami Oolite. Other natural constituents found in ground water will precipitate phosphorus and will break down nitrates. The Department's review of the Navy's application included an analysis of the proposed injection well design, the geologic, hydrogeologic, and water quality data and test reports provided in the permit application, and certain geologic literature, including the McKenzie report and other studies. Because of the known existence of the Key West lens, the Department required the Navy to submit more water quality and geologic data than would normally be submitted for a Class V injection well. Rule 17-28.520, Florida Administrative Code, provides, in pertinent part, as follows: The variety of Class V wells and their uses dictate a variety of construction designs consistent with those uses, and precludes specific construction standards for each type of Class V well outlined in this rule. However, a well must be designed and constructed for its intended use, in accordance with good engineering practices, and the design and construction must be approved by the Department. Rule 17-28.530, Florida Administrative Code, provides, in pertinent part, as follows: All Class V wells shall be operated in such a manner that they do not present a hazard to an underground source of drinking water. ... Rule 17-28.620, Florida Administrative Code, provides, in pertinent part, as follows: All owners of operators of Class V wells shall obtain a two-part Construction/Clearance permit ... The applicant shall submit to the Department at least the following information before receiving permission to construct: * * * Well location and depth, and casing diameter and depth for all water supply wells on the applicant's property, and well location for all water supply wells of public record within a 1000 foot radius of the proposed well; Description and use of proposed injection system, including type and construction of injection wells, physical and chemical analyses, estimated quantity, pertinent bacteriological analyses of injected fluid, and any proposed pretreatment; Proposed drilling and testing plan for any exploratory borehole or exploratory well proposed for the purpose of determining feasibility of Class V well injection at the site; If the flow of surface or other waters is directed by ditches or other artificial methods to the well, a delineation of the area drained by these features shall be provided. Rule 17-28.610(2), Florida Administrative Code, prohibits the injection of contaminants into underground sources of drinking water where the contaminant may cause a violation of any primary drinking water regulations under Chapter 403, Florida Statutes, and Chapter 17-22, Florida Administrative Code, or where the contaminants may adversely affect the health of persons. The Navy has provided reasonable assurances that the injected storm water will have no effect on G-II groundwater, that the injected storm water will have little or no effect on the water quality of G-III groundwater, and that the injected storm water will not result in a violation of the minimum criteria and standards for G-II and G-III groundwater. Further, the Navy has provide reasonable assurances that the proposed injection wells will not cause or contribute to any adverse effects on public health. These findings are based, in part, on the design of the surface water management system, on the different permeability of the geologic formations that underlie Key West, the biological and chemical factors in the saline environment into which the storm water will be injected, and on the pressure gradients and other dynamics of the Key West Lens. Although there was some disagreement among the various expert witnesses who testified in this proceeding, the most persuasive testimony establishes that the water discharged through the injection wells will not reach the Key West lens and that the water will likely have no detectable levels of contaminants if it ever reaches Florida Bay.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department enter a final order issuing the requested permit for the injection wells with all conditions contained in the notice and intent to issue. DONE AND ORDERED this 30th day of June, 1993, in Tallahassee, Leon County, Florida. CLAUDE B. ARRINGTON 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 30th day of June, 1993.
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant fact are found: On May 3, 1989, Cersosimo submitted an application for a Management of Surface Water Permit to the District. Subsequent to the submission of this application, the Polk County Board of County Commissioner (Commissioners) added an additional requirement to Cersosimo's Planned Unit Development (PUD) that there was to be a pre- development/post-development match for basin runoff in the event of a twenty- four hour one hundred (100) year storm event, i.e. following completion of this project (post-development) it will handle the same outflow or flow of storm water for the twenty four-hour one hundred-year storm event as in a pre- development situation. Based on the Commissioners' requirement, the design of the PUD was amended to provide for the required storage capabilities. On July 26, 1990, Cersosimo submitted to the District, its amended application, Management of Surface Water Permit No. 405733.01 incorporating the changes necessitated due to the Commissioners' additional requirement as to storm water runoff. On August 24, 1990, Ramon E. Monreal, P.E., of the Polk County Engineering Division, noted in a letter of that same date referring to Cersosimo's modification of Retention Pond No. 300 for the project in question that "this revision appears to meet the PUD condition by the Board of County Commissioners for drainage and compliance with the Surface Water Management Ordinance". The application of July 26, 1990, amends the original application by superceding and replacing that application. In connection with the application for permit, soil borings were taken at the site location for the retention ponds in order to establish the elevation of the seasonal high water level (SHWL) for that site. The borings indicated an elevation for the SHWL of 110 feet to 112 feet above mean sea level (AMSL). The District conservationally established the elevation for the SHWL of this particular site as 112 feet AMSL. The floor elevation of the lowest retention pond was established at 114.00 feet AMSL. The elevation of the surface of Lake Mabel for the ten year flood warning Level is 114.50 feet AMSL as established by Rule 40D-8.624(1)(z), Florida Administrative Code. District policy requires the floor elevation of a dry retention pond to be a minimum of one foot above the established elevation of the SHWL of that particular site. Even though the surface elevation of Lake Mabel for the Ten Year Flood Warning Level was established as 114.50 feet AMSL, there is insufficient evidence to show that there was lateral migration of water from the lake's edge to the site of the soil borings such that it was evidenced by a demarcation in the soil profile. To the contrary, the evidence shows that there were demarcations in the soil profile to establish an elevation for the SHWL for this site of 110 feet to 112 feet AMSL. The designed weir crest in the lower retention pond, Pond No. 300, has an approximate elevation of 118.50 feet AMSL which prevents water from coming over the top into the pond in the event Lake Mabel reaches the ten year flood level warning elevation of 114.50 feet AMSL. The distance from the present water edge of Lake Mabel to the bottom of Pond No. 300 would be approximately 600 feet, laterally and if the lake reached the ten year flood level warning elevation of 114.50 feet AMSL, the lake's water edge would be approximately 100 feet laterally from the bottom of Pond No. 300. There was sufficient evidence to show that even if the surface elevation of Lake Mabel reached the ten year flood level warning of 114.50 feet AMSL and the SHWL (ground water level) reached 112 feet AMSL, the retention ponds as presently proposed with a floor elevation of 114.00 feet AMSL would still percolate sufficiently, even though the percolation may be diminished from what it would be under present conditions, so that there would still be a pre- development/post-development match for basin runoff. Cersosimo can give reasonable assurances that the surface water management system as presently proposed will not diminish the capabilities of Lake Mabel to fluctuate through the full range established for it in Chapter 40D-8, Florida Administrative Code. Among others, the following specific conditions in pertinent part will be placed on the permit, if granted: . . . The applicant shall visually monitor the ponds on a monthly basis to ensure that the ponds are dry within 36 hours from the end of the last rainfall event. Should the ponds fail to percolate the required water quality volume per District criteria, a permit modification shall be required. . . .
Recommendation Based upon consideration of the foregoing Findings of Fact and Conclusions of law, it is, recommended that the Southwest Florida Water Management District enter a Final Order granting the application for Management Surface Water Permit No. 405733.01, as proposed by the District.

The Issue The issue to be resolved in this proceeding concern whether a modification of a general permit should be issued by the Respondent agency Department of Environmental Protection (Department), to the Respondent, Chuck Emling, so as to allow construction and operation of a stormwater discharge facility on Emling's property in Gulf Breeze, Florida.
Findings Of Fact The Respondent Chuck Emling, intends to build a sports complex, herein known as the "Club Property." He obtained a general stormwater discharge facility permit therefor, since his property represents a drainage area of approximately 10 acres in size, well under the threshold of 100 acres or less by which a general permit may be granted and because he proposes to construct and operate the facility such as to retain the first one-half inch of run-off. Because his plans for the sports complex and attendant stormwater discharge facility changed he applied for a modification of that general permit, which was duly noticed by the Department and protested by the Petitioner herein. The Petitioner is concerned that overflow from the retention areas will be channeled onto his property and that the berm at the northeast corner of the project site will cause natural stormwater flow to be diverted onto Workman's property which formerly flowed across Mr. Emling's property. The Petitioner contends that a landowner, such as the applicant, may not construct a berm along the borders of his property to prevent surface waters that would otherwise naturally flow onto his property from doing so, under generally accepted principles of real property law.1 The Department is an agency of the State of Florida charged, as pertinent hereto, with authority to regulate stormwater discharge facility construction, design and operation, pursuant to the legal authority cited herein. The proposed project is approximately ten acres in size and the project is expected to exceed all required standards for stormwater retention. The facility, as proposed in the modification application, will store approximately 18,254 cubic feet of run-off water and percolate it through its retention system within approximately seventy-two hours. The modified facility will store between 97,000 and 110,000 cubic feet of stormwater for percolation which is approximately five times greater than that required by regulations contained in Chapter 62-25, Florida Administrative Code, concerning storage of one- half inch of run-off, if the drainage area served by the stormwater facility is 100 acres or less. The subject project site is approximately 10 acres in size. Prior to development of the Club Property, an "equalization pipe" ran under Crane Cove Boulevard providing for run-off of stormwater which was in excess of the amount that could be retained in the low-lying area immediately to the west of Crane Cove Boulevard and the Club Property. This was designed to allow such excess water to flow back onto the Club Property as well as to allow stormwater run-off on the Club Property to the east to reach the inlet of the equalization pipe to flow westward into the depressed area to the west of Crane Cove Boulevard. In other words, flow was permitted in both an easterly and westerly direction to equalize excess stormwater on both properties and to permit continuance of the historic east-to-west flow of stormwater over the land surface of the properties involved herein, after the installation of the obstacle consisting of Crane Cove Boulevard. Installation of the pipe and Crane Cove Boulevard occurred before the installation of the berms around the boundary of the applicant's property which are a part of the subject project. The equalization pipe under Crane Cove Boulevard has now been connected to an extended pipe running under the Club Property all the way to the boundary of the Club Property which joins the Workman property. Some surface waters that historically and naturally flowed back onto the Club Property from the depressed area to the west of Crane Cove Boulevard, if that area flooded, and which are kept off the Club Property by the berms, can now pass through the equalization pipe without flowing onto or across the Club Property, which thus prevents the stormwater facility proposed to be installed from treating off- site stormwater. The pipe is supposedly sited and installed at an elevation so as to allow discharge off the Club Property only of stormwater in excess of the retention and treatment standard sub judice, which is that the facility will retain on-site all stormwater run-off resulting from less than a 100-year storm event. Thus, for this reason, there is little likelihood that stormwater will be discharged onto the Workman property from this pipe from the Club Property and the applicant's proposed stormwater facility. It is also unlikely that stormwater will traverse the equalization pipe and its extension to the boundary of the Workman property from the west since, if the depressed area lying west of Crane Cove Boulevard floods, the stormwater collected there would more likely migrate westward since that is the direction of natural flow. The Petitioner's case, on direct and through cross- examination, establishes two problems with the application for permit modification as proposed. First, the elevation of the weir on the eastern boundary of the Club Property, next to the Workman property, which allows water to be discharged through the pipe from the Club Property onto the Workman property, above a certain level, is purportedly at a lower level than the calculations provided by the applicant's engineers. Their calculations indicate what they believe is necessary to retain stormwater up to the volume of a 100-year storm event before it can spill onto the Workman property. The Petition contends the calculations indicate that the weir would thus have to be at an elevation of 19 feet to retain stormwater to that level or volume, but the applicant's plans and evidence show variously that the weir would be either at 18.9 feet or at 18.3 feet. Additionally, the modification plan increases the size and configuration of the earthen berm around the northern end of the Club Property, moving it more toward the outer northern boundary along U.S. 98. The Petitioner demonstrated two problems with the size, configuration and location of the berm in this area of the property, that is the northern side of the Club Property in the area where it joins the northwest portion and boundary of the Workman property. First, the Department of Transportation (DOT) drain structure in the highway right-of-way of U.S. 98, at that point, is being subjected to siltation caused by unstabilized earth eroding off the berm and toward and into the drainage structure. This can cause downstream siltation pollution as well as actual physical blockage of all or part of the drainage capability of this structure. In addition to the possible pollution hazard posed by this situation it can also result in water ponding on the Workman property through impedance of proper drainage. Additionally, the configuration, size and location of the berm on the northeast corner and portion of the applicant's property may cause "backing up" or ponding of water on the Workman property. The erosion to the berm must be stabilized properly and the berm should be so located and configured near this northeast corner of the applicant's property and the northwest corner of the Workman property and other necessary steps taken so as to prevent the ponding of water onto the Workman property. A grant of the permit should be so conditioned. The modification application proposes erosion control measures, including sod and landscaping, to enhance and preserve the stormwater system's integrity. During construction the project and site will be protected from soil erosion and sedimentation. Protective measures will include, as a minimum, installing staked hay bales and silt and sediment fencing downhill from any earth work activity, prior to the start of construction. The project specifications require all soil erosion and sedimentation to be controlled during construction and retained on-site. The stormwater collection and treatment system will require periodic maintenance for continued proper operation, including removal of silt and debris from infiltration areas and maintenance of vegetative cover. The grant of the permit should be conditioned on these steps being strictly followed, especially with regard to proper design and configuration of any berm and sod of it, so as to prevent erosion and resulting sedimentation into the DOT drainage and stormwater treatment system consisting of the culverts and swales along Highway 98. It is critical that those DOT structures and systems be maintained in proper operating condition and not impeded by construction and operation of the proposed project so as to prevent the ponding of water on the adjacent property owners' land. The pre-development stormwater discharge rate for the project site, as shown in Appendix D to DEP Exhibit 3, was 6.55 cubic feet per second. The proposed project will retain all stormwater on-site with up to 100 percent of the volume caused by a "100-year storm." This means that the proposed 24-foot weir will be set at a minimum elevation of 18.3 feet, so that no stormwater will be discharged from the site until it reaches at least an elevation of 18.3 feet. It will discharge less than the predevelopment amount of stormwater after that point or once the surface water elevation in the retention system exceeds 18.3 feet. Thus the Club Property stormwater design will lessen the impact on all properties to the east of the development, and to the west as well, because all stormwater will be retained unless it exceeds the volume of 100 percent of a 100-year storm falling on the site area. Thus the pre-development discharge of 6.55 cubic feet per second will be entirely eliminated unless such a storm intensity and volume is reached. Even if the pond were to reach its maximum elevation, a discharge to the east towards Workman's property would only be 6.44 cubic feet per second or slightly under the pre-development discharge rate. When the project is completed a "junction box" will be placed at the end of the mitered end section of the 18-inch pipe on the Club Property. The side discharge slot on that junction box will be set at an elevation of 18.3 feet. Therefore, no discharge from the Club site can flow toward Crane Cove Boulevard to the west unless a storm event in excess of a 100-year storm occurs, because only such an event would cause water to exceed that elevation. Thus, by not otherwise discharging from the site through the pipe the project will result in a lessening of any previous impacts on properties both west and east of the subject site from stormwater discharge. The testimony of Mr. Leland Empie, a surveyor, testifying for the Petitioner, contains discussion of a purported wetlands area lying just west of the Club Property, across Crane Cove Boulevard and south of Highway 98. That wetlands area, if indeed it is a jurisdictional wetlands area, which was not definitively established, is only approximately one and one-half acres in size. Mr. Empie also postulated that there may be a wetlands area on the Club Property but that could not be definitively determined, as he admitted himself. He testified that he saw no definitive indication of jurisdictional wetlands on the project site and the area in question has been "cut and filled" so it is difficult to determine the fact of existence of any wetlands area on the Club Property. In any event, there has been no showing that the subject project will discharge stormwater to any wetland except possibly the wetland west of Crane Cove Boulevard, assuming that it qualifies as a jurisdictional wetland, which has not been proven. If that were the case, the discharge would only occur at a volume and level in the stormwater system which exceeds that of a 100-year storm. If such a discharge occurs it will still be, as found above, at a volume-per-day less than the historic run-off volume from the subject property in its predevelopment stage. In summary, no preponderant definitive evidence was offered to prove that jurisdictional wetlands exist on the project site. The Petitioner's surveyor witness, Mr. Empie, relied on overlays of data from federal map sources to determine the purported location of wetlands on a map but could not verify the accuracy of the maps nor explain the difference in the manner in which jurisdictional wetlands are determined by the Northwest region of the Department versus the method used by the federal agencies referenced in his testimony.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is RECOMMENDED: That a final order be issued by the Department of Environmental Protection approving the requested modification of the Respondent-Applicant's stormwater discharge general permit in the manner recommended and conditioned herein. DONE AND ENTERED this 10th day of May, 1999, in Tallahassee, Leon County, Florida. P. MICHAEL RUFF 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 Filed with the Clerk of the Division of Administrative Hearings this 10th day of May, 1999.
Findings Of Fact By application filed on September 9, 1980, Respondent/Applicant, John H. Land Builders, Inc., sought a permit from Respondent, Department of Environmental Regulation (DER), to conduct dredge and fill activities in an approximate one acre area located in the southeast corner of a proposed housing development in Section 10, Township 29 South, Range 19 East, in Hillsborough County, Florida. A copy of this permit application may be found as DER Composite Exhibit B. Specifically, Land sought to excavate 4,100 cubic yards of material (muck) and to backfill the area with 14,400 cubic yards of granular material from adjacent uplands to allow for development of a street and building lots in an unnamed wetland. A permit from DER is required because the project involves a wetland that is contiguous with a ditch that connects to the Palm River, all of which constitute waters of the State that are subject to dredge and fill permitting requirements. The plans have been reviewed by other state and local authorities in the Hillsborough County area, and no adverse comments have been received. After the installation is completed, the elevation of the land will be raised, and will permit five homesites to be built on the land as well as the construction of an access road to the property from an adjacent street. The installation in question is but a small part of a larger proposed housing development known as Timberlake Subdivision that will ultimately involve more than 300 homesites. However, no further dredge and fill activities under DER jurisdiction will be undertaken. The proposal of Respondent/Applicant was received by the Department and certain timely additional requests were made from the Department to the Applicant to provide information necessary to evaluate the request for permit. Applicant subsequently furnished the required information, and it may be found in DER Exhibit C. The Department performed a field inspection and review of the dredge and fill site, including the surrounding areas, to assess the impact of water quality caused by proposed dredging and filling activities in wetlands areas. It concluded that the Applicant had affirmatively provided reasonable assurance to the Department that the short-term and long-term effects of the activity would not result in violations of the water quality criteria, standards, requirements and provisions of Chapter 17-3, Florida Administrative Code. A copy of the permit application appraisal may be found in DER Exhibit A. On January 21, 1981, DER issued its Intent to Issue a dredge and fill/water quality certification with certain conditions therein, including the requirement that future development be dependent upon separate stormwater review by the Department (DER Exhibit D). On October 20, 1980, Applicant filed a Notice of Stormwater Discharge with the Department's Southwest District Office in Tampa (DER Composite Exhibits B & F). Thereafter, the Department conducted a field inspection and review of the proposed housing development and surrounding areas to determine whether the proposed stormwater discharge would have a significant impact on water quality. Based upon the results of that inspection, which concluded that the proposed discharge would not have a significant impact on the waters of this State, the Department issued Applicant a stormwater exemption on November 7, 1980. The project site is located in an unnamed wetlands area. It is weedy and has a dense cover of primrose willow (Ludwigia peruviana), willow (Salix caroliniana), cattail (Typha sp.), red maple (Ace rubrum) and is overgrown with grapes vines (Vitus rotendifolia). It lies just to the north of a series of fish farms owned by Petitioner, Penisular Fisheries, Inc. Other commercial industries and single family dwellings are found south of the proposed activities. To the west and northwest lie marshlands, two old borrow pits, and Interstate Highway 4. Water runoff from the dredge and fill area will flow to the storm drainage system in the proposed street, and from there to a designated retention pond. Because there will be minor contaminants in the runoff, the water will be retained for treatment for a period of five days, which exceeds the 100 hour retention period required by DER. After treatment, the runoff will flow into a well-defined county drainage ditch west of 58th Street, travel down the ditch which lies adjacent to the fish ponds, and then meander into the existing marshland. Water runoff from the remainder of the project (excluding the dredge and fill area) will drain into the two existing borrow pit lakes which lie close to Interstate Highway 4. The designated retention pond will be located west of the project and has a controlled spill-off elevation. It will provide sufficient treatment to and cleaning of the water to insure that no violation of water quality standards will occur. A stormwater system to be constructed by Applicant will actually reduce the volume of water runoff now occurring. Reasonable assurances have been given that the short-term and long-term effects of the proposed activity will not result in violations of the water quality criteria, standards, requirements and provisions of the Florida Administrative Code. Based upon Use location of the point of discharge of Land's proposed stormwater discharge, the volume and frequency of discharge for which the proposed facilities are designed, and the anticipated constituents of discharge, the proposal will not have a significant impact on the water quality of the waters of this State. Accordingly, the exemption from stormwater licensing requirements was properly issued by the Department. Water quality violations which were alleged to have existed in a ditch on property adjoining the properties of Land and Petitioners were the subject of a notice of violation issued to the owners of that property. However, no notice of violation was ever issued to Land. Further, the ditch is not a part of the installation proposed by Applicant for issuance of the dredge and fill permit. Petitioners' concern is that Applicant has not given reasonable assurance that water quality standards would not be violated by the stormwater discharge and that downstream waters might be contaminated by urban runoff from the project. In reaching that conclusion, Petitioners' expert relied on a review of certain materials submitted to him by Petitioner's counsel. He did not visit the project site, nor had he reviewed drainage plans or construction drawings for drainage improvements contemplated by the notice of stormwater discharge filed by Land.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that Respondent Department of Environmental Regulation grant the requested dredge and fill permit/water quality certification to Respondent/Applicant John H. Land Builders, Inc. It is further RECOMMENDED that the Respondent Department of Environmental Regulation enter a final order confirming the stormwater exemption issued by the Department to Respondent/Applicant on November 7, 1980. DONE and ENTERED this 27th day of April, 1981, in Tallahassee, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 27th day of April, 1981.
Findings Of Fact Mr. Cutter has resided in Taylor County, Florida since 1974. His home is approximately 8,000 feet southwest of the Fenholloway River on the north side of Courtney Grade Road. DEP is responsible for administrating the Water Quality Assurance Trust Fund. DEP's responsibilities include the undertaking of water supply restoration projects in appropriate circumstances. In administering this trust fund, DEP determines whether specific ground water supplies are contaminated. This determination generally requires DEP to evaluate whether a given water supply meets primary drinking water quality standards. A primary drinking water standard is a regulatory criterion adopted by the state pursuant to delegated federal authority. Such a standard refers to a certain maximum level for a given contaminant which, if exceeded, represents a health risk. If DEP finds that a primary drinking water standard is violated, it performs a cost analysis to determine the appropriate means of restoring or replacing a water supply source. In the late 1980's, DHRS received complaints from Taylor County residents that water from their private wells looked, smelled, and tasted bad. DHRS asked DEP to investigate those complaints. DEP's initial investigation of ground water quality did not reveal a public health threat. Nevertheless, DEP decided to proceed on the assumption that industrial effluent in the Fenholloway River could represent a public health threat. DEP first considered the potential of conducting chemical analysis of ground water to detect the presence of chemical markers that would indicate the presence of water from the Fenholloway River. In order to do this, DEP would have to isolate a chemical compound from the industrial effluent in the Fenholloway River that would serve as a "marker" for contaminated effluent. DEP attempted to determine the influence of the Fenholloway River using a test measuring non-purgeable total organic halides, or NPTOX, as a chemical marker. DEP's projections relying upon NPTOX as an indicator for river water proved to be unreliable. DEP correctly rejected the use of NPTOX as a chemical marker because it occurs naturally and does not provide a clear indication as to whether river water influences ground water. Moreover, DEP identified laboratory quality assurance problems for tests using this chemical. DEP's scientists do not know of any practical chemical marker that can identify mill effluent in river water. Research is emerging which may identify a chemical test which will reveal the presence of effluents from kraft paper mills. However, the academic community has not yet validated their use. After the shortcomings of chemical analysis became evident, DEP decided to conduct a ground water study to reach conservative findings regarding the extent to which water from the Fenholloway River could potentially impact ground water supplies in a worst case scenario. DHRS agreed to certify that it would be in the interest of public health to connect homes to a public water system if DEP could identify a corridor where river water influenced ground water. As a result of the ground water study, DEP prepared and adopted the 1995 report titled "Delineation of Ground and Surface Water Areas Potentially Impacted by an Industrial Discharge to the Fenholloway River of Taylor County, Florida" (1995 Report). The 1995 Report identified a conservative potentially impacted corridor within which water from the Fenholloway River might interact with ground water in the adjoining aquifers as well as the potential impact of river flood waters on ground water. Buckeye is a softwood kraft pulp specialty mill that has been in operation in Taylor County since 1954. It discharges treated effluent into the Fenholloway River in accordance with permits from DEP. The mill discharges effluent upstream of U.S. 19 Bridge. This discharge creates a mounding effect, i.e. an artificial high level within the river. Because the river downstream of the discharge point is maintained at an artificially high level during drought conditions, a "mound" of water forms where the water level in the aquifer connects to the river. During a dry season, this discharge will be maintained, but the aquifer on both sides of the river will continue to drop due to a lack of recharge from rainfall. The river generally runs from east to west through Taylor County. It starts in the San Pedro Bay at 100 feet above sea level and ends at the Gulf of Mexico at sea level. Ground water (subsurface water) moves from higher to lower elevations of the water table. Elevations (contours) of equal ground water levels can be mapped just as elevations of land surfaces are mapped. Ground water contour lines (sometimes called equipotential lines) depict points of equal ground water elevation. Direction of ground water flow is always at right angles to the contour lines. Ground water is a dynamic system impacted by rainfall, which adds water to the system, and discharge points, which take water from the system. Water is constantly entering (recharging) or leaving (discharging) the aquifer, which causes the ground water levels to be continually changing. The Floridian aquifer system underlies all of Florida, including the study area of the 1995 Report. The aquifer at issue here is unconfined from San Pedro Bay to the coast. Potentiometric (aquifer water level) elevations of the Floridian aquifer in the study area of 1995 Report show that ground water moves southwesterly. The dominant direction of the ground water flow in this area is parallel to the river. Under normal conditions, with normal rainfall, the river is a focal point for ground water discharge. In this situation, rain recharges the shallow aquifer so that the water level elevations in the aquifer are higher than the water level elevations of the river. Consequently, ground water moves into the river, making it a "gaining stream." In periods of drought when the rainfall is deficient, the recharge is deficient and the water level in the aquifer can decline to points that are lower than the elevation of the water level in the river. In that instance, water can leave the river. If water migrates from the river into the ground water, the river is called a "losing stream." When water leaves the river and migrates outward, it will be influenced by the dominant regional flow that is parallel to the river and downstream. River water can migrate outward a limited distance before it becomes influenced by the regional flow and migrates back to the river. Migration back to the river occurs when water level elevations in the aquifer are higher than they are in the river and the river becomes a "gaining stream." The purpose of the 1995 Report was to define a potential corridor of river influence, using the worst case scenarios in all hydrogeologic conditions. It relied primarily on potentiometric (aquifer water level) studies, as opposed to a chemical analysis of ground water quality. DEP's report relied on differences in water elevations in the river and ground waters. The 1995 Report also relied upon United States Geological Survey (U.S.G.S.)/ U.S. Department of Housing and Urban Development flood prone area maps to delineate the extent of river water flooding on surrounding land surfaces. The area of the study was from east of the mill to County Road 356 in the west, including U.S. 98 to the north and Courtney Grade Road to the south. DEP has not discriminated against certain residents of Taylor County by not extending the geographic boundaries of the study area. The study did not end at Golf Course Road. In order to prepare the MODFLOW model which ultimately led to the MODPATH model, DEP installed additional monitor wells to the west of Golf Course Road. These additional wells provided DEP with ample water level data to perform the models. The monitor wells were more concentrated near the discharge point of Buckeye's mill. However, there were greater fluctuations in water levels in that area. DEP's decision to limit the study to the area depicted in the report was based on technical and policy considerations. Water levels in the areas to the west of the study do not fluctuate very much. Additionally, the influence of the tide from the Gulf of Mexico decreases the impact of river water on ground water south and southwest of the study area. The population in these areas was relatively low. Because the population of Taylor County is dispersed, it is not cost-effective or feasible for DEP to consider the extension of water lines beyond the boundaries of the study area. Mr. Cutter lacks standing to claim that the study did not extend far enough to the west. The western portion of the river beyond the limit of the study could not adversely impact ground water supplying the well on Mr. Cutter's property. DEP collected sufficient data and made an appropriate analysis of the total area depicted in the 1995 Report. The 1995 Report did not use water quality data as a primary or sole indicator of effluent extent. However, it did consider some supplemental chemical concentrations to evaluate water quality. These concentrations were always at or below normal background levels and therefore were consistent with the conclusions in the report. DEP used three techniques to determine the furthest lateral distance that river water could potentially migrate into ground water in the adjoining aquifers. Two techniques (cross-section model and steady-state ground water model) were used to determine the extent of migration during the worst case dry season scenario. The third technique (flood season map) was used to determine the extent of influence on ground water during the worst case river flooding scenario. The cross-section technique used to model the worst case dry season scenario relied upon historical data from the driest period on record (using data from Suwannee River Water Management District, U.S.G.S. and Buckeye monitoring wells), which was April 2, 1989. Using this data, DEP prepared a potentiometric map. A computer program interprets data from a contour map and, given horizontal and vertical axes at given points, produces cross-sections. The cross-sections are made at various angles of the river to determine "stagnation" points," i.e. points where the ground water gradient between the aquifer and the river is zero. DEP staff connected the stagnation points revealed by the cross- section method and transposed them onto a potentiometric map for May 25, 1994 (a dry period where sufficient data was available). This process allowed DEP to define the total area where the river would impact the aquifer during the dry season. The results of the cross-section technique showed that the migration of river water into ground water occurs during dry seasons almost entirely on the north side of the river. It confirmed the analyses of the MODFLOW and MODPATH models discussed below. DEP used a steady-state simulation flow mode as one of the three study techniques in the 1995 Report; it was based on the worst case dry season scenario of April 25, 1989. This model allowed computer tracking of simulated particles (representing river water) in a portion of the 17-mile (north-south) by 20-mile (east-west) grid used in the model. The computer model shows how simulated particles during the worst case dry season conditions: (1) enter the aquifer when the river is higher than the ground water; (2) move away from the river when the river elevation is higher than water level elevations in the adjacent aquifer; (3) reach a "stagnation point" where the elevation of river water that has entered the aquifer is equal to that of the unaffected portion of the aquifer; and (4) subsequently flow parallel with the river and eventually back to the river. The objective of the steady-state ground water flow model (MODFLOW) is to incorporate the best available data so that calibration of model parameters can be accomplished by using measured ground water heads for a specific "snap shot" in time. Once an acceptable calibration of the model is obtained by minimizing the residuals of modeled versus measured heads, then the water budget is decreased by a recharge package so that the model heads closely reflect an observed "worst case" dry season head distribution. After an acceptable dry season head match is obtained, a particle tracking program (MODPATH) is used to delineate effluent migration from the river-to-aquifer and from the aquifer-to- river. U.S.G.S. developed MODFLOW which is a reliable numerical ground water model. DEP used MODFLOW to simulate water levels and to depict hydraulic conditions in the subject area. In the instant case, DEP first examined available data such as water levels, rainfall, and hydraulic conductivity, to develop a conceptual model. The conceptual model determines the size of the model and presents a hypothesis regarding how the area of interest will operate. The development of the conceptual model includes the determination of boundary conditions. Boundary conditions are mathematical instructions which the modeler uses to simplify the model. They reflect the conditions at the geographical limits of the model. DEP used "no-flow" boundary conditions for the north, east and south boundaries. These conditions represent areas where water outside the boundaries flows away from the model. DEP used a "constant head" boundary condition for the western boundary of the model, i.e. a determination that the ground water level does not fluctuate substantially in that area. In developing the conceptual model, DEP also considered relative recharge throughout the area, relative hydraulic conductivity, and drainage conditions. "Calibration" refers to a process where a modeler adjusts factors within the model to minimize the difference between measured water levels and simulated water levels. DEP initially calibrated the MODFLOW model to simulate hydrologic conditions on May 11, 1994. Next, DEP calibrated the MODFLOW model to simulate hydrologic conditions on April 25, 1989 which represents a worst case scenario for a dry season in the study area. U.S.G.S. also developed MODPATH. It is a computer model which uses MODFLOW head (water level) data to simulate the direction of ground water flow. The software simulates where a particle of water would flow based on head data provided by the MODFLOW model. In this case, the MODPATH model yielded a conservative projection of areas where ground water could be impacted by water from the Fenholloway River in a worst case dry season scenario. DEP used a flood season map to delineate the worst case flood season scenario. Historical data indicates that the worst surface river flood on record was Hurricane Dora on September 10 - 13, 1964. DEP used a U.S.G.S. flood prone area map to show the extent of river flooding during Hurricane Dora. DEP conservatively assumed that river flood waters could affect the ground water in the area flooded by the river during this storm. The flood prone map shows areas of inundation flooding from the river and areas of drainage flooding experienced during Hurricane Dora in 1964. The term inundation flooding refers to water that has been in the river which is transported to a certain distance as it floods out of the river banks. The term drainage flooding refers to rainfall which accumulates in a depressed area. Drainage flooding is influenced by the intensity and duration of rainfall and the slope of the depressed area. Since 1955 the U.S.G.S has compiled river water level data in the subject area. Hurricane Dora represents a conservative worst case scenario for a wet season or flood because the water levels resulting from that storm were higher than the levels at any other time in recorded history. Areas outside of the delineated corridor may be flooded from time to time. However, they represent isolated wetlands which are not connected to the Fenholloway River. Therefore, there is no need to include them in the corridor of potentially impacted areas. The corridor in DEP's 1995 Report includes: (a) the entire river flood plain inundated by Hurricane Dora during the worst case flood scenario; (b) the potential extent of river influence during the worst case dry season scenario; and (c) all areas where simulated particles in the steady-state simulation flow computer model computer model migrated from river to ground water, including areas of very low potential. DEP based the computer modeling in the 1995 Report on reliable data from historical records and from the network of monitoring wells in the study area. DEP had sufficient data from the monitoring wells to develop valid ground water elevation maps in the study area for the computer modeling. U.S.G.S. topographic maps are reliable as to elevation numbers. They are commonly relied upon by geologist to determine the direction of surface water flow. U.S.G.S. flood prone area maps depict areas that are impacted by river inundation and are commonly relied upon by geologists. DEP geologists reasonably relied upon the U.S.G.S. flood prone area map of the river. U.S.G.S. river elevation recording station data (from bridges at U.S. 27, U.S. 19 and Route 356 near Hampton Springs) are commonly relied upon by geologist. DEP used proper methods to determine how river water moves during flood conditions. DEP properly excluded from consideration areas that were flooded during Hurricane Dora by local rainfall as opposed to river water. The corridor identified by the 1995 Report correctly reflects a conservative depiction of an area where the river water could influence the ground water in the worst case dry season scenarios, both actual and simulated; it also conservatively depicts the area where the river water could influence surface and ground waters in the worst case flood scenario. The 1995 Report appropriately concluded that there was no potential for areas beyond the defined corridor to be impacted by the industrial waste discharged into the river. Mr. Cutter's property is located within the study area of the 1995 Report but outside the corridor delineated in the report. His property is about one mile from the edge of the 1964 worst case scenario river flood plain. It is situated close to monitoring well number PM02. State agencies have tested Mr. Cutter's well water on several occasions. They have never found any violations of drinking water standards or any exceedances of health advisory levels. Based on the steady-state simulated computer model, river water will not impact Mr. Cutter's property during a dry season worst case scenario. During dry seasons, it is not possible for river water to migrate 8000 feet to Mr. Cutter's land because ground water in the shallow aquifer on the south side of the river is moving from higher to lower elevations toward the river. Consequently, there is no potential for Mr. Cutter's land to be affected by river water during a dry season. River water did not effect Mr. Cutter's property during the 1964 worst case flood scenario, as revealed by the recorded extent of river flooding and the elevation of his land. During Hurricane Dora, the flood elevation of the river was 25 feet above sea level at the nearest point to Mr. Cutter's land which is at least 27-28 feet above sea level. The differences in these elevations makes it impossible for river water to Mr. Cutter's land during the worst case flood scenario. During the 1984 storm, Mr. Cutter's land was about 7-8 feet higher than the recorded maximum river flood waters. The greater weight of the evidence indicates that any flooding on Mr. Cutter's land at that time was the result of drainage or rainfall flooding and not the result of inundation from the Fenholloway River. In the 1994 storm, Mr. Cutter drove from Waldo Springs near the river to his home through less than 18 inches of water. The water was deep enough to reach the floorboard of his vehicle. Mr. Cutter acknowledges that if the topographic maps relied upon by DEP are correct, he would have driven through five feet of water in order for flood water from the river to have reached his land. He stated that the water at his house or in the area between his house and the river was not five feet deep. There are isolated sloughs in the area of Mr. Cutter's land. However, there are no sloughs that continuously extend from the river to Mr. Cutter's property. Therefore, flood water from the river cannot reach Mr. Cutter's land by running through sloughs. Natural conditions, including the decay of organic matter, can cause surface and ground water discoloration. If a well is located near a slough or wetlands, percolation from the slough or wetlands can result in brown well water. There is no persuasive evidence that the discoloration of Mr. Cutter's well water is the result of contaminated river water. The high ground water elevations between Waldo Springs and Mr. Cutter's property act as a barrier to any ground water movement to the southwest in the direction of Mr. Cutter's property. One resident witness testified that his well was contaminated by ethyl dibromide (EDB), a pesticide with no link to river water or kraft pulp mill effluent. EDB is a nematicide commonly used in crops such as citrus and soybeans. It is also used in turf management for golf courses and landscaping projects. Buckeye's mill in Foley, Florida produces fluff wood pulp that is used in products like diapers. It also produces special dissolving wood pulps that are used by the filter industry (including air and oil filters) and the filament industry (including rayon clothing and specialty rayon products used in tire cords). In the kraft pulp mill process, the mill withdraws about 47-50 million gallons per day (MGD) of ground water from the wellfield and discharges about 50 MGD of treated effluent from an aeration pond into the river. The mill has a sewer system that captures the effluent from the manufacturing process. It also has about 150 acres of aerated treatment lagoons. During the time that DEP was studying the issue that resulted in the 1995 Report, Buckeye spent about $2 million providing free bottled water to Taylor County residents and paying the City of Perry to run water lines to homes of people who complained about their well water. Buckeye has a monitoring network of wells around the mill. It maintains liners under its lagoons. Buckeye's interest in this proceeding is: (a) to ensure that it can continue to discharge under its permits from DEP; and (b) to support the 1995 Report of DEP even though Buckeye takes the position that the corridor in that report should be narrower. Buckeye has provided a sufficient basis to support its status as intervenor.
