Findings Of Fact Ann Keller was granted a variance to construct a dwelling ten feet from the front property line at 601 Oberlin Drive, Clearwater, Florida, and these proceedings follow an appeal from that decision of the Board of Adjustment and Appeal on Zoning. The area is zoned RF-75 (single family) and the proposed construction conforms to this zoning. This lot has a drainage easement over the back one-half (away from Oberlin Drive) which leaves a minimum depth of approximately 30 feet from the drainage easement to the front of the lot. Without the requested variance of 15 feet from the 25- foot setback, there would be little more than five feet on which to build. With the requested variance, Petitioner proposes to construct a residence 65 feet wide and 20 feet deep. Appellant contends that the area is subject to flooding, the drainage easement on this lot includes a cemented culvert 21.5 feet wide, the creek flowing through this culvert frequently overflows and floods Oberlin Drive and yards across Oberlin from this lot, yet no evidence was submitted to show how or why the construction of a residence on this lot would affect the flooding of Oberlin Drive or the adjacent lots. Protestants contend the area is in a flood plain and homes should not be built in a flood plain. The extent of this flood plain was not shown so it cannot be said that protestants' homes are not also located in this flood plain. The setback variance is the only variance requested and here involved.
Findings Of Fact The Parties The Applicant, Trail Ridge Landfill, Inc. (Trail Ridge), is a corporation formed in 1989 for the purpose of developing a landfill project and providing waste disposal capacity for the City of Jacksonville. Trail Ridge Landfill, Inc. is a wholly-owned subsidiary of Waste Management of North America, Inc. Its operating division is involved in the waste collection, recycling and disposal business. Waste Management of North America, Inc. is a wholly-owned subsidiary of Waste Management, Inc., which is involved in all facets of solid waste collection and disposal nationally. The Florida Department of Environmental Regulation (DER) is an agency of the State of Florida charged with the responsibility of regulating solid waste management facilities and with permitting their initial construction and operation. It is charged with reviewing applications for permits for construction of such facilities, for reviewing applications for dredge and fill permits in wetlands or waters of the State and, as pertinent to the project involved in this proceeding, for storm water management and storage of surface water and the regulation thereof through its permitting and enforcement authority contained in Chapters 403 and 373, Florida Statutes, and Titles 40C and 17, Florida Administrative Code. The Petitioners are Coastal Environmental Society, Inc. (CESI), a not- for-profit Florida corporation established for the purpose of protecting natural resources. St. Johns Preservation Association, Inc. (SJPA), also a not-for- profit Florida corporation established for the purpose of protecting the community, including environmental concerns; Baldwin-Maxville Coalition, Inc., also a not-for-profit corporation established to promote the health and welfare of its community, including environmental concerns; William McCranie, a resident of Jacksonville, Florida; Darryl Sperry, a resident and citizen who lives 1 1/4 miles from the proposed landfill site in Baker County. All Petitioners have been established to be substantially affected by the proposed permitting and the projects related thereto and all have met pertinent standing requirements as a matter of fact and law. The Respondents do not contest the standing of the Petitioners. Background and Purpose of the Project The purpose of the proposed landfill facility is to address the solid waste disposal needs of the City of Jacksonville and Duval County (the City). The City currently disposes of solid waste at two landfills. One is on the east side of Jacksonville on Gervin Road, and the other is located in the north area of Jacksonville on Island Road. The presently used, east landfill is an unlined landfill currently operated pursuant to a DER Consent Order, in connection with which closure of that landfill is planned. The north landfill consists of three unlined cells and one lined cell. The City currently has unused landfill capacity at these two landfills which will last approximately one more year, but has also sought approval for expansion of the north landfill which would provide about two more additional years of capacity, if approved. The proposed landfill project, if approved, constructed and operated, would meet these solid waste disposal needs for approximately 20 to 25 years. The project at hand began when the City issued a Request For Proposal for private companies to submit bids to the City for construction of additional landfill capacity somewhere to the northwest of Jacksonville in Duval County. Two companies that met qualifying requirements submitted proposals in response to the request for proposals. Trail Ridge was one of those two qualifying bidders. The City selected the Applicant for contract award and then entered into a contract. The Applicant has an option to purchase the proposed landfill site from Gilman Timber and Land Company (Gilman, Gilman Paper Company). After issuance of the permits to the Applicant, the option would be exercised. Thereafter the property would be immediately conveyed to the City from the Applicant. Thus the site of the proposed facility will ultimately be owned and controlled by the City, although the Applicant will operate the landfill under its contract with the City. Gilman presently uses the 1,288 acre site and several thousand surrounding acres for growing timber, principally pine trees, in a pine plantation-type operation grown for use as pulp wood. Much of the site and surrounding Gilman land is characterized by pine trees grown to an age of 20 years or less and then harvested. A great deal of the site property has recently been cut, chopped, plowed re-bedded and re-planted with pine trees. Although some of the site is characterized by mature timber, much of the timber has been recently planted or is otherwise timber not yet mature enough for harvest. The option agreement provides that Trail Ridge will purchase the property from Gilman for $10,000 per acre. The City will then purchase the 1,288 acres from the Applicant for $2,600 per acre, which the Applicant maintains is the current, fair-market-value for the land as it is currently used as pine plantation for growing pulp wood. These terms and conditions are a part of the City's Request For Proposals. In addition to paying the Applicant $2,600 per acre for the 1,288 acre site, the City will pay the Applicant a fee over the life of the operation of the proposed landfill. The fee, amortized over the 20- year span of the agreement, will make up the difference between the Applicant's $10,000 per acre purchase price paid to Gilman and the City's $2,600 per acre initial purchase price paid to the Applicant. The City will thus ultimately re- pay Trail Ridge the $10,000 per acre for the purchase price for the property. The Applicant corporation will operate the landfill over its entire useful life and then close it. Thus, the Applicant's own figures show the land is valued at $3,348,800. The record does not reflect the reason for the purchase price paid to Gilman being $12,880,000, of which the City will repay $9,000,000 to the Applicant in the form of the operation fee, over and above the initial payment to the Applicant of $3,348,800. In any event, the utilities payment to the Applicant of the $12,880,000 for the land and the operation of the landfill only represents the recompense to the Applicant for the purchase funds expended for it to buy the site from Gilman. Additionally, the Applicant, through its option agreement with Gilman, is required to pay Gilman a $60,000 per month option fee. $15,000 per month of that must be paid during the pendency of the option, with the remainder of the $45,000 monthly fees due upon closing of the purchase. The portion of the operation fee paid by the City over and above the $2,600 per acre initial purchase price, attributable to the land appraisal itself, will be paid by the City on the basis of a certain dollar fee-per-ton of solid waste handled and disposed of in the landfill by the Applicant. Testimony indicates this will be approximately $8.00-$15.09 per ton, although the evidence as to which amount is indefinite. The testimony of Applicant's witness Allen, in any event, references these amounts as applicable to the City's solid waste "stream" handled by Trail Ridge at the proposed facility. Its contact with the City assures the Applicant of a minimum of 569,000 tons of waste per year to which the fee would apply. The City currently generates approximately 750,000 tons of waste per year. There is no evidence of what the construction or other capital costs or operation expenses related to the proposed facility will be over the useful life of the facility for the Applicant or related corporations. Site and Design The proposed site is 1,288 acres in size, located in southwestern Duval County, approximately three miles south of Interstate Highway 10, 1.5 miles west of U.S. Highway 301 and 1.14 miles north of State Road 228. The site is located in a sparsely populated area approximately 4 to 6 miles from the City of Baldwin, 5 miles from the City of Macclenny and 2 miles from the City of Maxville. A substantial portion of the proposed site will be left undisturbed and used as a buffer area to separate it from any surrounding development. There are water supply wells within fairly close proximity to the site. One well is within a mile of the site and three are approximately 1.5 miles southeast of the site. The proposed facility will include both a Class I and Class III solid waste disposal area. The Class I area will be approximately 148 acres in size, and the Class III area, 28 acres. The Class III disposal area will only be used for non- household refuse such as construction debris, tree and shrubbery clippings and the like, which will not generate deleterious substances in liquid or gaseous form, as will the Class I landfill. The remainder of the 1,288 acres will be used for buffer zones, dirt borrow areas, storm water management facilities and ancillary facilities necessary to the day to day operation of the landfill. No part of the Class III disposal area will be located within 200 feet of jurisdictional wetlands, which are the closest bodies of water. The project will be located on "Trail Ridge," which is a relatively elevated geographic feature, extending generally in a north-south direction in western Duval County. Geologically, it is an ancient sand dune. There is a substantial decline in elevation of this portion of the ridge from west to east, which produces surface water drainage patterns in a west to east direction at the site, also accompanied by surface water drainage patterns in a southerly- northerly direction into wetlands which occur on the south and north verge of the site, because the site is a prong or easterly extension of Trail Ridge lying between wetlands which occur on the northerly, southerly and easterly boundaries of the Class I disposal site. The 1,288 acres, including the landfill sites themselves, have been used for silvi-culture practices since 1948 or earlier, and are currently managed primarily as a slash pine plantation grown for pulp wood purposes. The present owner of the site, Gilman Paper Company, plans to continue this use of the site should the landfill project not be approved and constructed. Since 1948, the entire site, including much of the wetlands thereon, have been logged, some portions of it as many as three times. The silvi-culture practices at the site include clear- cutting, chopping, burning, harrowing, tilling and bedding of the soil, and planting of pine trees. The pine trees are grown to be harvested on a 20-year cycle or less. Due to these intensive silvi-cultural practices, the natural conditions of the site have been significantly altered and much natural vegetation, such as bottom-land hardwoods, has been replaced by planted pine trees. The area has been extensively ditched for drainage purposes and logging roads have been constructed throughout the site. The design of the Class I disposal area of the landfill includes three major components: a liner system, which includes a permanent leachate collection and removal system, a cap and closure system and a gas control system. The Class I disposal area is designed to be 140 feet high when the landfill is completed and closed in approximately 20-25 years. It will have typical landfill refuse "lifts," of approximately 8 to 12 feet in height, with a side slope grade of three horizontal feet to one vertical foot of elevation gain. This is the maximum grade steepness allowed by DER rules. The Class III landfill, in which no household garbage, chemicals, oils and greases or other deleterious substances will be deposited, will include only a cap and closure system. In order to carry out Department regulatory requirements designed to contain waste permanently in a well- defined area and to minimize the amount of leachate produced within a landfill, as well as to collect and remove leachate that is produced, the landfill will have, in effect, a double liner system. The liner system is designed to contain the leachate produced when rain water contacts waste in the landfill and to cause that leachate to percolate vertically downward through the landfill, capture it in the liner system, prevent it from contacting groundwater and to remove it and treat it. Leachate from the Class I disposal area will be contained by the liner system and removed by a leachate collection and removal system. The liner system, starting from the bottom and proceeding upward, will consist of a 6 inch thick layer of compacted, subgrade soil. Over that layer, a prefabricated "bentonite" clay-like material will be deposited. Directly over the bentonite layer will be a high density polyethylene liner (the secondary liner) called a "geomembrane." The bentonite material has the characteristic of swelling when contacted by a liquid so that, if the geomembrane leaks, the bentonite will swell and plug the hole in the liner above it. On top of the bentonite layer and the geomembrane layer, is a synthetic drainage material called "geonet." Geonet has a very high transmissivity rate and therefore has great capacity to conduct water within its own plane. Lying immediately above the geonet material is a geotextile filter designed to keep sand out of the pores or interstices of the geonet. Above that geotextile filter is a second geomembrane (the primary liner). Above the second geomembrane is another geonet layer, as well as another geotextile filter layer. Then to protect the entire liner system from damage, two feet of clean sand will be placed above the uppermost geotextile filter layer. The two feet of sand also acts as a drainage layer for the uppermost geonet. The leachate that percolates down through the waste and the sand will contact the geonet and then be carried down slope on top of the geomembrane. This constitutes the leachate collection system. The bottom geonet is called the "leak detection system." This is because, if a hole develops in the primary liner, any leachate coming through the hole will be quickly drained away through the bottom geonet. The bottom geonet thus operates as a backup leachate collection system, since any leachate reaching the bottom geonet will also be discharged into the leachate removal system. If a leak should develop in the secondary liner, the bentonite material would quickly plug the leak, swelling and absorbing that liquid. The Petitioners have stipulated that the Applicant has proposed a liner system and leachate collection system for the Class I disposal area which meets all criteria of Chapter 17-701, Florida Administrative Code, except as to the requirements of Rule 17-701.050(5)(c), (e)3. and 4. and (f)3., Florida Administrative Code. The Applicant demonstrated that the liner system and leachate collection system will meet the criteria of Rule 17- 701.050(5)(c), Florida Administrative Code. The liner system will be installed in accordance with a quality assurance plan. A specific condition already agreed upon will require the Applicant to submit for approval a revised quality control and assurance plan for installing the Class I synthetic liner system, after selection of the liner manufacturer and prior to the liner's installation. The liner system is designed so that it will be protected from puncture by waste materials or landfill operation equipment. In addition to the two feet of sand placed on top of the entire liner system to protect it, when initial waste disposal begins, the first lift of waste across the entire area of the liner system, as it is installed in phases, will be composed of 6-8 feet of "select waste" to protect the liner from puncture. Select waste is waste containing no pipes, roots or other potentially puncturing objects which could penetrate the sand layer to damage the liner system. A quality assurance engineer will be on site full-time supervising the initial placement of the select waste until that phase of the landfill operation is completed. A grant of the permit should be so conditioned. The Applicant has established that the liner system and leachate collection system will meet the criteria of Rule 17-701.050(5)(e), Florida Administrative Code. The leachate depth on top of the primary and secondary liners will not exceed a foot because the geonet has the capacity to quickly remove leachate from the liner. The actual hydraulic head of leachate on the primary liner will be only approximately 1/4 inch. The depth on the secondary liner was shown to be even less. The liner system and leachate collection system will meet the criteria of Rule 17-701.050(5)(e)3. and (f)3., Florida Administrative Code. The design of the collection system, including the geotextile filter, will prevent clogging of the system throughout the active life and closure period of the landfill, primarily by placing a gravel aggregate around the collection pipe so as to prevent debris from entering the system. A pilot line will also be installed in each collection pipe to facilitate access for mechanical cleaning, should it be necessary. In the unlikely event of an obstruction in the system, the leachate would simply bypass that area and continue down-grade to the next downstream leachate collection pipe and be removed from the landfill for treatment by that means. The liner system and leachate collection system will also meet the criteria of Rule 17-701.050(5)(e)4., Florida Administrative Code. The leachate collected will be carried downhill to pipes at the east end of the landfill. The leachate will then be pumped from the pipes into storage tanks. Trucks will then be filled with leachate to be transported to the City's Buckman Regional Wastewater Treatment Plant, owned and operated by the City, for treatment and disposal. Unrefuted evidence shows that this plant has adequate capacity and treatment capability to safely treat and handle the leachate. The truck loading areas will be equipped with berms and other means of protecting the surrounding wetlands, surface and groundwaters from leachate spills during the truck filling process. The Applicant's evidence does not demonstrate, however, that the tanks themselves and the area surrounding them will have protective measures for containing leachate spills. In order to comply with the above rule, the totality of the evidence concerning the leachate collection, disposal system and treatment method demonstrates that the tanks should be accompanied by a surrounding containment system (walls or berms) which will have the capability of containing the entire capacity of a tank should failure of a leachate collection tank or related piping or valving occur. Any grant of the permit should be so conditioned. The Petitioners have stipulated, and the Department agrees, that the Class III disposal area is exempt from the liner system and leachate collection system requirements of the above-cited rule provisions. Covering and Closure System Both the Class I and Class III landfills are designed with a composite soil covering system to minimize the amount of rainfall which can come into contact with the solid waste so as to minimize the creation of leachate. During the day to day landfill operations, a 6 inch initial cover will be applied to enclose each Class I landfill disposal cell on a daily basis, except for the working face itself, where waste is currently being deposited. The working face may be left uncovered, so long as solid waste is scheduled to be placed on it within an 18 hour period. A 6 inch initial cover will also be applied once every week to enclose each Class III landfill disposal cell. Thereafter, an intermediate cover of one foot of compacted earth will be applied on top of the initial cover within seven days of initial completion, if a final cover or additional lift on top of that completed cell is not to be applied within 180 days of cell completion. The initial cover will consist of sandy soil, over which will come the intermediate cover of one foot of compacted earth. The final cover will be applied to those portions of the landfill which have been filled with waste to the extent of designed dimensions at the time those portions have been filled. The final cover, to be placed on the sides of the landfill and ultimately upon the top at the end of its useful life, will be placed on top of the 12 inches of intermediate soil layer and will consist of 12 inches of compacted clay with a permeability of 1 X 10/-7 cm/sec. Next will come a layer of 12 inches of compacted soil and then a final layer of 12 inches of top soil, upon which the Applicant will plant grass for erosion control. Erosion of the cover layers on the side slopes is designed to be minimized by closing areas of the landfill as they are filled, an operational procedure commonly referred to as "close as you go." The final cover layers placed on the landfill outside of the clay cap are designed to allow the establishment of a planted grass cover as soon as possible to minimize erosion of the cover material and the side slopes. In addition, the intermediate cover placed on top of and between each cell, beneath the clay layer surrounding the outside perimeter of the landfill, has a high permeability, thereby acting as a drainage layer to direct rainfall and leachate vertically downward to the leachate collection system, as well as to collect runoff so as to retard erosion. Erosion is also retarded, as is the runoff of storm water/leachate over the side slopes of the landfill, by containing storm water which comes into contact with the working face of the landfill cells. This will be accomplished by minimizing the size of the working face to approximately 42 feet width. This will serve to reduce the potential for storm water to contact waste. Additionally, berms will be constructed around the working faces of each active cell which will cause any runoff or storm water which gets inside the working face of the cell to remain there and to percolate through the land fill to eventually be collected as leachate by the collection system. If enough rain falls on the working face of a cell to cause an overflow of storm water over the berms, additional berms placed on the interior slopes of the landfill will catch the overflow and divert it back through the landfill and the leachate collection system. The Applicant contends that normal maintenance equipment and personnel will be able to maintain the exterior side slopes of the landfill and thus minimize erosion. However, if erosion should become a problem, the Applicant proposes to install interceptor berms constructed on the side slopes, accompanied by various geotextural fabrics or synthetic materials proposed to be imbedded on the side slopes to help anchor the interceptor berms. These berms, however, have been demonstrated by Petitioner's witness, Mr. Peavy, to be inadequate to retard erosion. In fact, they may promote erosion because they would be insufficiently anchored to the side slope (as designed with 3:1 slope) and the downhill slope of the berms themselves is considerably steeper than a 3:1 ratio, which will actually promote erosion. The erosion problem will be discussed in further detail infra, but the proposed "optional" berm system, consisting of two proposed berms down the length of the 450 foot side slope will have to be redesigned in order to serve the purpose of retarding side slope erosion. The cap or cover for the exterior side slopes of the landfill will consist of a relatively impermeable clay layer overlain by a sand layer, as well as a top soil layer. Mr. Lithman, an expert in geotechnical engineering testifying for the Applicant, established that as a result of the side slope stability analysis he conducted of the clay layer for the Class I disposal area, that the clay layer would be stable, with a safety factor of 2.9-3, which is more than adequate for a slope as designed for the Class I disposal area (3:1). Mr. Evander Peavy, testifying for the Petitioners and accepted as an expert witness in the fields of civil engineering, soil mechanics, surface water hydrology and hydraulics, agreed that there was an adequate safety factor in the clay cap layer itself and that no plane of failure would likely occur in that layer. The problem, however, lies in the sand layer immediately predetermined or potential plane of failure will occur at the interface between the sand layer and clay layer. This is where the side slope of the landfill is most likely to fail. Failure means that the weight of the sand and soil layers on the outside of the clay layer would exceed the resisting forces, holding them back on the slope of the landfill, which would result in a deformation, slumping or break in the sand layer. If this slumping or break occurs in the sand layer and is not immediately repaired, rain water can erode the clay layer, which is highly erodible if exposed to rainfall. If not redressed soon, this could result in exposure of the waste of the landfill to rain water with the result that leachate could seep out of the side slopes of the landfill and enter surface waters of the State through the functioning of the storm water system. The most likely layers a civil engineer would analyze to determine the stability of the side slope would be the sand and soil layers above the clay layer because they are the weaker layers in terms of adhesion, shearing and resistance to downward movement under stress. However, Mr. Lithman, Trail Ridge's expert who conducted a side-slope stability analysis, only analyzed failure in the clay layer initially, until he was called on rebuttal to address findings of Mr. Peavy. The DER rule provision that allows 3:1 ratio side slopes for the sides of such landfills only serves as a guideline or maximum steepness criteria for design engineers. It does not relieve an engineer from analyzing slope stability in accord with good engineering practices. Analyzing side slope stability must be done in terms of establishing "safety factors." An acceptable safety factor for a landfill is 1.5 because, if failure occurs, solid waste can quickly be uncovered which can cause leachate contamination to surface waters of the State. A safety factor of 1.5 is the commonly accepted factor for earthen dam design because of the risks posed by failure of such slopes or embankments. Mr. Peavy is extensively experienced in the design of earthen dams and similar earth works, including extensive analysis of slope constituents and design for stability under shear forces and other failure-inducing factors, as well as for resistance to erosive forces. He was engaged in such phases of engineering work for approximately 26 years, during which period he designed and oversaw construction of numerous dams, revetments and other earthen embankments and works of many types. Because of this, and because of the commonly accepted engineering methods and calculations he used in analyzing the stability and integrity of the side slopes of the landfill, involving plane of failure analysis and erosion damage analysis, his testimony is credited over that of the other witnesses testifying on the subject matters involving side slope integrity of the landfill. Because of this, a safety factor was established for the side slopes of the landfill, for the sand and soil layers of 1.5. Safety factors of 1.25 are indeed commonly used for highway embankments, but highway embankments are not designed with predetermined or potential planes of failure, such as is involved at this landfill (as presently designed) between the sand-soil layers and the clay layer. Trail Ridge's expert witness in this area, Mr. Lithman, had testified that a safety factor of 1.25 would be adequate because it was typical of DOT earthen embankments for roadways. Mr. Niehoff testified that a 1.3 safety factor was sufficient. In fact, however, Mr. Peavy, testifying for the Petitioners, calculated the safety factor of the side slopes of the landfill to actually be 0.85, using his initial assumption of a weight for a cubic foot of the sand-soil layer of approximately 100 pounds. Mr. Niehoff testifying for Trail Ridge found no basic fault with Mr. Peavy's analysis of the safety factor and alleged that his analysis was done with accepted engineering procedures, but only with use of slightly different assumptions. He testified that if he had used the same assumptions as Mr. Peavy, he would have reached the same conclusions. Mr. Peavy also calculated his safety factor again by employing the same equation used by Trail Ridge's expert, Mr. Lithman, and assumed instead that the unit of sand-soil layers was 125 pounds per cubic foot, as did Mr. Lithman. This assumption coupled with the internal angle of friction of 35 degrees used by Mr. Peavy, which was shown to be a conservative assumption, resulted in a calculated safety factor of 1.05, which is still unacceptable, even under Mr. Lithman's analysis, because Mr. Lithman opined that the safety factor should be 1.25. Using Mr. Peavy's equation, but his own assumptions as to angle of friction and weight per cubic foot of the sand-soil layer, Mr. Niehoff, testifying for the Applicant, calculated a safety factor of 1.3. This safety factor also is unacceptable because it is less than the 1.5 safety factor established as proper by Mr. Peavy's testimony and, indeed, if Mr. Lithman's safety factor of 1.25 could be deemed acceptable, the 1.3 figure would result only in a marginal safety factor at best. The major difference between the safety factor calculations of Mr. Peavy and Mr. Niehoff is that Mr. Peavy assumed that the sand-soil layer above the clay layer would be saturated, while Mr. Niehoff assumed that only 19 inches of the 24 inch sand-soil cover layer would be saturated by rainfall. However, Trail Ridge's own experts, Mr. Lithman and Mr. Niehoff, offered conflicting testimony between themselves on the amount of saturation to be expected. Like Mr. Peavy, Mr. Lithman did his analysis on the basis that the sand-soil layers would be saturated completely, contrary to Mr. Niehoff's subsequent testimony that this would not happen beyond a 19 inch depth in the layer. Mr. Niehoff's conclusions that the sand-soil layer would not become saturated or valid only if there is a complete grass cover over the entire side slopes of the landfill. He admitted that if the sand-soil layer became saturated, the safety factor would only be 1.1 or less according to his own calculations. Trail Ridge offered no preponderant evidence to establish that an adequate grass cover could be established so as to prevent saturation of the sand-soil layer during the design 25-year, 24-hour storm event (approximately 8- 9 inches rainfall in 24 hours). The evidence indicates, rather, that establishing and maintaining a grass cover on the side slopes of the landfill will be very difficult to achieve on a uniform, completely grassed basis. This is because of erosion and because of the damage by equipment necessary to repeatedly repair erosion damage and because of the fact that much of the side slopes of the landfill will be, in effect, under construction until the landfill is completely built out and completed at the end of approximately 20 years. Even if the lower several lifts of the landfill, when covered on the "cover as you go" basis can achieve them, more recently deposited, will not have a complete grass cover. Thus, there is a substantial likelihood of saturation of the sand-soil layer, during storm events of the type for which the landfill is designed. Further, the volume of water that would saturate into the sand-soil layer, even if the landfill was completely grassed, will still be sufficient to totally saturate the lower 90 feet of the landfill side slopes above the clay layer in the event of a 25-year, 24-hour storm event. If the sand-soil layers become saturated, sloughing or failure of those layers will occur at the toe of the landfill. If that occurs, then the clay layer, protective cap can be quickly eroded by subsequent rainfall and surface runoff. This will cause the waste within the landfill to be exposed to rainfall, generating leachate which can migrate to the surface of the landfill and thence to the storm water system and ultimately to the surface waters of the State. No provisions have been made in the design to remove water from the sand-soil layers once it reaches the area near the toe of the landfill to prevent sand-soil layer failure. The impermeability of the clay layer would prevent the rainfall from migrating through the clay layer and continuing to the interior bottom of the landfill to be collected properly as leachate because the clay layer properly should be an impermeable barrier to storm water. Thus, a saturated condition of the sand-soil layers would be most likely to cause their sloughing and failure near the toe of the landfill, with resulting damage by erosion or cracking to the clay layer with the effect of allowing leachate to escape to surface waters of the State. Although the Applicant's expert, Mr. Lithman, opined that side slope stability had not been a problem with the 3:1 ratio slopes at the City's Rosemary Hill Landfill, he admittedly was unaware of the height or length of the side slopes of that landfill. The longer the side slopes and the higher the landfill, the more likely it is that the sand-soil layers will become saturated and fail during design storm events or shortly thereafter, especially as the landfill, in its later years is built both longer and higher toward its final configuration. Further, Mr. Lithman and the Applicant's evidence does not reveal the composition of the side slopes of the Rosemary Hill Landfill, in terms of whether or not the clay and sand-soil layers designed in the proposed landfill are present. Due to the height of the proposed landfill, the lengths of its side slopes and the absence of design features such as terraces and benches, failure of the side slopes, especially in the later years of the landfill's life and, indeed, after closure (closed landfills can generate leachate) is likely to occur, based upon the facts established through Mr. Peavy's testimony. The likely side slope failure is a result of the design flaw and is not a problem which can be cured by normal operation and maintenance activities. Indeed those activities may aggravate the problem through their deleterious effect on the establishment of a uniform, complete grass cover. Because of the height of the proposed landfill, the length and slopes of its sides and the lack of design features such as benches or terraces, it is likely to experience significant side slope erosion due to storm water. The volume of rain water that would accumulate and flow down the sides of the landfill will achieve velocities which would destroy even a well established grass cover, especially in the later years of the landfill's life when the sides have reached significant length and height. Storm water would thus gain sufficient velocity to destroy a grass cover and to particularly attack those portions where the grass cover is incomplete, thinned or possessed of an insufficient root mat to hold the soil. Once erosion starts, small rills will form which will soon develop into deeper gullies, ultimately penetrating the sand-soil layer. It can then quickly erode away the resulting exposed clay cap layer, exposing the waste to storm water. Leachate could thus leak from the landfill. Because of the present design of the Class I landfill, the only way to repair erosion damage is to push material from the bottom with heavy machinery, such as bulldozers. These erosion maintenance activities themselves would prevent the establishment of a uniform solid grass cover. The presently operated East Landfill in Duval County exhibits both side slope failure and erosion damage due to rainfall on its 3:1 slopes, including damage to the grass cover. Erosion damage to the slope layers due to erosion maintenance activities of the type which would be necessary to repair damage at the proposed landfill has occurred. Both erosion and side slope failure will ultimately result in exposure of solid waste to rainfall runoff and assure side slope seepage of leachate. The material eroded or sloughed away from the side slopes can obstruct the drainage conveyance system surrounding the landfill, rendering the MSSW/storm water system inoperative. Because of the presently proposed design of the landfill, it would be impossible to effectively correct side slope erosion or failure, due especially to maintenance activities. Even if a uniform grass cover could be established in the last years of landfill operation and after closure, the great length and slope of sides of the landfill by that time would result in erosion even if the grass cover were initially uniform and solid on the entire slope of the landfill. A change in the design of the landfill, however, whereby 15 foot wide benches or terraces would be incorporated into the sides of the landfill every 20 or so vertical feet, would likely prevent the side slope erosion and failure established to be likely by Mr. Peavy. In fact, benches or terraces similar to those found to be required by Mr. Peavy have had to be recently installed at the East Landfill in Duval County in order to resolve side slope erosion and failure problems on those 3:1 slopes. The mere installation of interceptor berms, as depicted in TRL Exhibit 28, would not alleviate side slope failure and erosion problems, but rather would aggravate them and would reduce the safety factor of the side slopes to 0.5. Consequently, in order to grant the permit, it should be conditioned on the landfill being re-designed and constructed so as to incorporate benches or terraces at approximately 20 foot intervals on the slope of the landfill from bottom to top. Although this may potentially reduce the volume of space within the landfill, depending on how it is accomplished, it has been established that, without the use of the bench or terrace system, pollutant leachate cannot be reasonably assured to be prevented from entering State waters and wetlands. Leachate Control Leachate is any water coming in contact with solid waste. The chemical constituents of leachate which are present and will be present in the Duval County solid waste stream, to be disposed of at the proposed landfill, include chlorobenzene, volatile organics of various types, benzene, acetone, phenolic compounds, gasoline constituents, chloroform, methylethylketone, methylene chloride, toluene, xylene, ethylbenzene, total organic carbon, nitrogen, phosphorus and metals such as aluminum, chromium and zinc. Leachate thus contains toxic, hazardous and priority pollutants which will be disposed of in the landfill. The breakdown and degradation of solid waste can also generate additional toxic or hazardous compounds and substances. Leachate can potentially be discharged in a proposed landfill into groundwater and surface waters in a number of ways, including leakage from the bottom of the landfill liner into groundwaters, including into the Class I storm water pond and surface waters of the State through discharge from the groundwater into the storm water pond system. It could also be deposited into the storm water system through spillage of leachate where tanker trucks are loaded, through seepage of leachate through the side slopes of the proposed landfill by damage to the integrity of those side slopes as found above. The Petitioners maintain that side slope seepage of leachate will occur because the permeability of the intermediate cover layers surrounding the cells of the landfill is significantly less than the permeability of solid waste. This will have the result, according to Petitioners, that leachate will migrate horizontally through the intermediate cover layers to the sides of the landfill. Once there it arguably would migrate to the surface of the landfill side slopes through erosion of the outer cover, and fissures in the clay due to drying from exposure to the sun and through erosion. Additionally, the Petitioners maintain that leachate will migrate downward through the peripheral intermediate cover layer under the clay and contact the impermeable clay anchor cap, build up hydraulic head pressure and thus seep out through landfill sides near the toe of the landfill. The Petitioners maintain that Trail Ridge's policy and proposal to punch holes in the intermediate cover layers atop the cells of the landfill to encourage downward migration of leachate and discourage horizontal migration of leachate through the intermediate cover layers will be ineffective because the intermediate cover is more permeable than the solid waste itself so that punching holes in the intermediate cover to allow the leachate to migrate down through solid waste will actually not occur. Additionally the Petitioners contend that the filter system and the storm water pond will not treat the dissolved chemical components of the leachate specified in Petitioner's Exhibit 2 and that these dissolved components will move through the sand filters into waters of the State. Contrary to Petitioner's contentions, however, the Applicant has demonstrated that leachate will not avoid capture by the leachate collection system by seeping horizontally through the cover or cap and out the sides of the landfill, provided that the side slope failure and erosion prevention measures found to be necessary in the above Findings of Fact are instituted in the design, construction and operation of the landfill. The design of the cap and closure system is basically a side slope seepage prevention system, except for the absence of terraces or benches. The intermediate soil cover beneath the clay cap and surrounding each cell of the landfill acts as a drainage medium. It will channel any seepage of leachate from the cells of solid waste through the permeable, intermediate soil cover, generally in a downward direction, both in and between the cells of the landfill throughout its cross-section, as well as downward through the intermediate soil cover lining immediately beneath the clay cap around the periphery of the landfill. This system, if the above design deficiency is corrected, will tend to force the leachate downward into the collection system, as opposed to horizontally out the cover or the sides of the landfill. The reason this system will work in this manner is because the intermediate cover soil is more permeable than the solid waste itself. The permeability of the intermediate cover will promote vertical movement of the leachate because, as the leachate migrates across each cell, it will encounter the vertical, intermediate soil cover layer at the side of each cell and that will promote its moving downward toward the collection system. The water in the landfill will thus follow the path of least resistance, so that the vertical portions of the intermediate cover layers surrounding each cell and surrounding the sides of the landfill beneath the clay cap, coupled with the force of gravity, will provide a preferential path downward toward the leachate collection system. This finding includes consideration of the Petitioners' contention that leachate will migrate downward and contact the impermeable clay anchor cap and build up head pressure so that it will seep out of the sides at the toe of the landfill. The intermediate cover layer underlying the sides of the landfill beneath the clay anchor cap is connected with the leachate collection system underlying the bottom of the landfill. Thus, a continuous conduction of leachate down through the intermediate cover, permeable layer will allow the leachate to seep downward all the way to the leachate collection system rather than pooling behind the impermeable clay anchor cap. This condition will be enhanced by the fact that surrounding each cell is the approximately vertical, permeable intermediate cover layer, throughout the entire cross-section of the landfill, such that much of the leachate will migrate downward in the interior of the landfill. Because of the ready conductance of leachate in a downward direction by the intermediate cover layers, Trail Ridge's policy of punching holes in the intermediate cover layer on the top of each cell in order to seek to prevent side slope seepage of leachate will be ineffective because the intermediate cover is more permeable than the solid waste. Thus, this procedure is unnecessary and, in fact, could become counter-productive to the extent that punching holes in the intermediate cover would allow rain water mixed with leachate to contact more of the solid waste contents of the landfill as it migrates down through the interior of each solid waste cell. This would result in a more highly concentrated form of leachate, which could pose more deleterious threats to ground and surface waters should it escape to ground and surface waters. Therefore, any grant of the permit should be conditioned on a prohibition of the Applicant thus violating the integrity of the intermediate cover layer overlying each cell as the landfill is built up in lifts. Gas Control System The Class I disposal area is designed with a gas control system which will prevent explosions and fires caused by the accumulation of methane gas due to decomposition of the waste in the landfill. The gas control system will prevent damage to the vegetation on the final cover of the closed portions of the landfill or vegetation beyond the perimeter of the property. It will prevent objectionable odors off site. The Petitioners have stipulated that the Applicants' gas control system will be designed in accordance with Rule 17- 701.050(5)(j), Florida Administrative Code. Although the Petitioners presented testimony of various persons who live in close proximity to other landfills, which were at one time operated by Waste Management subsidiary companies, neither the persons who testified of odor problems at those landfills, nor other witnesses presented testimony to show whether any of the landfills utilized a gas control system or one of equivalent design to that proposed for the subject facility. No evidence was presented to support a finding that the proposed landfill facility would produce objectionable odors to any significant degree. The Petitioners have further stipulated that the Class III disposal area is exempt from the gas control system requirements set forth in Rule 17- 701.050(5)(i) and (j) and (6)(i), Florida Administrative Code, and the Department agrees. Hydrogeology and Ground Water Monitoring The Applicant filed as part of its application, and placed in evidence, a hydrogeological survey and groundwater monitoring plan, contained in TRL Exhibit 51. The hydrology of the proposed landfill site may fairly be characterized as complex because it contains many different features such as recharge and discharge areas, varying zones of conductivity, a sand component to the surficial aquifer as well as a rock aquifer component and multi-directional groundwater flows. Additionally, wetland systems occur down-gradient from the higher levels of the surficial aquifer on the north, east and south sides of the proposed Class I disposal area. From the surface grade down to a depth of approximately 100 feet lies the surficial aquifer, which primarily consists of a coarse sand medium. Lying below the sand aquifer is a confining unit (relatively impermeable) identified as the Hawthorn Group, which consists of denser marls, dolomites and silver clays. Beneath the Hawthorn layer, at a depth of approximately 300-400 feet, is the Floridan aquifer, which serves as the principal deep water supply source for this part of Florida. Additionally, immediately above the Hawthorn layer in the deep zone of the surficial aquifer, a "rock aquifer" exists under a portion of the landfill site, generally the eastern-most portion. It was not shown to be continuous throughout the site. The rock aquifer is connected to the sand surficial aquifer lying above it. Zones of varying higher and lower permeability occur at various places within the surficial aquifer. Generally, groundwater at the site flows down-gradient in an easterly direction, caused by rain or surface water recharging the surficial aquifer on the higher portions of Trail Ridge, including the western side of the landfill Class I disposal site. The surficial aquifer then discharges this groundwater to the land surface and the wetlands lying on the eastern side of the site. Additionally, some northward and southward flow of groundwater occurs from recharge areas to the wetlands lying on the northerly and southerly boundaries of the Class I disposal site in the wetlands. The specific condition 19 contained in the Department's Notice of Intent to issue permit and draft permit requires the Applicant to periodically (quarterly) sample monitoring wells to ensure that water quality standards are not exceeded at the boundary of a zone of discharge established by that specific condition and authorized by Rule 17-28.700(4)(a), Florida Administrative Code. A groundwater monitoring plan has been developed by the Applicant, with accompanying hydrogeological survey as mandated by Rule 17-28.700, Florida Administrative Code. The proposed groundwater monitoring system consists of 42 monitoring wells in and around the area of the proposed Class I and Class III landfill sites. The system is designed to monitor upgradient and downgradient flows in wells constructed to sample from the shallow and intermediate zone and from the deep zone (to some extent) on the east boundary of the Class I disposal site. Specific condition number 18 of the Notice of Intent to grant the permit and draft permit, to which the Applicant has agreed, requires that a detailed chemical characterization of a representative sample of leachate be performed, so as to allow for any necessary modifications to the list of chemical substances to be analyzed in water samples drawn from the monitoring wells on a quarterly basis. Although there are up-gradient monitoring wells for the shallow and intermediate portions of the surficial aquifer, there are no upgradient monitoring wells for the deep zone of the surficial aquifer. There are no upgradient monitoring wells on the west side of the landfill in the deep zone. The deep zone of the surficial aquifer is the zone between the intermediate zone and the top of the Hawthorn confining bed. The rock aquifer is present beneath the proposed landfill site and was encountered at well locations B-7, B-8, B-12 and B-14. That rock aquifer is hydrologically connected to and part of the deep zone, which is hydrogeologically connected throughout the site to the uppermost portions of the surficial aquifer lying beneath the landfill. The rock aquifer is a significant source of drinking water in Duval County and the surrounding northeast Florida area and is used as a supply source for domestic and commercial wells within one and one-half miles of the landfill Class I site. "Sinkers" are immiscible liquids contained in landfill leachate that are denser than water. When released from the landfill they would sink to the first low permeability unit in the surficial aquifer. This would be at the bottom of the surficial aquifer at the rock unit. Once they encountered a lower permeability unit or strata, sinkers would then move in a more lateral direction downgradient in undetermined directions. The silty clay layer depicted on Figure 9 of TRL Exhibit 51 would intercept those sinkers and cause them to tend to move in a direction toward the silty clay layer intercepted by well B-1. At that point the sinkers would then have a tendency to move in a north or south direction on top of the confining zone. The direction those sinkers would move, following a gradient, cannot be determined at present from the groundwater monitoring plan because no deep wells are proposed in either of those areas which could detect sinkers. The groundwater monitoring plan is thus not adequate for the deep zone or to detect pollutants that could migrate off site in the rock aquifer because there are no monitoring wells in the deep zone on the west, north and south sides of the Class I landfill area. Monitoring for sinker compounds in the deep zones is thus insufficient and water supply wells nearby in the deep zone would be at risk because there is no way to detect pollutants between those water supply wells and the source of the pollutants at the landfill. The groundwater monitoring plan is inadequate because there is insufficient information to determine the direction of water flow in the deep zone. Sufficient upgradient monitoring wells in the deep zone are necessary in order to determine the direction of water flow in the deep zone which will in turn indicate where additional deep zone monitoring wells should be located to detect contaminants migrating off site. Leachates also contain contaminant constituents or compounds called "floaters." Floaters are immiscible liquids which are lighter or less dense than water. They tend to float on top of the groundwater table. The hydrologic information depicted with the application and the Applicant's evidence is not sufficient to determine where floaters might migrate. The shallow monitoring wells referenced in TRL Exhibit 42 would not adequately detect floaters at or near the water table surface. Due to the lower lying stream or wetland systems on the north and south side of the Class I landfill on Trail Ridge, groundwater flows in the vicinity of those areas are likely moving northward and southward to some extent. Thus, TRL Exhibit 51, and particularly Figure 14 of that exhibit, is insufficient to support a determination of where monitoring wells should be located because it does not include the impact of the stream or wetland systems on the north and south sides of the landfill. Groundwater contours bend into the stream areas on the north and south sides of the landfill which would indicate groundwater flow to the south and the north instead of just from west to east. The general shape of these contour lines would resemble the contour lines depicted in Figure 16 of TRL Exhibit 51. These contour lines bend back to the east and the west on the north and south sides of the Class I landfill. Since there is groundwater flow to the north and to the south from the Class I landfill, intermediate and deep monitoring wells in addition to shallow wells, should be located along the west, north and south sides of the landfill. Because they are not in the groundwater monitoring plan thus far, the plan is inadequate. A grant of the permits should be conditioned on such additional wells being installed and made a part of the monitoring program, in accordance with the above findings. A zone of discharge for the proposed landfill has been established pursuant to Rule 17-28.700(4)(a)2., Florida Administrative Code, which is intended to extend vertically from the base of the surficial aquifer and horizontally 100 feet beyond the footprint of the landfill or to the compliance groundwater monitoring wells, whichever is less. (See pages 611- 618 of the transcript.) Therefore, even if the groundwater monitoring wells are closer than 100 feet to the footprint of the landfill, they are to be used for monitoring for compliance with applicable water quality standards, including the primary and secondary drinking water standards for G-II groundwater, as contained in Rules 17-550.310 and 17-550.320, Florida Administrative Code. The Applicant has agreed to this location of the wells, their spatial relationship to the footprint of the landfill, to the zone of discharge and to their use for compliance purposes. Storm Water and Surface Water Management System The Applicant proposes as part of its permit application a storm water discharge and surface water management system. The application for permitting for that system was submitted to the DER which reviewed it using the Water Management District's permitting criteria set forth in Chapters 40C-4 and 40C- 42, Florida Administrative Code. Pursuant to its independent permitting authority set forth in Section 373.413, Florida Statutes, the DER noticed its intent to issue the MSSW permit to the Applicant, based upon its opinion that the project will comply with applicable rules. The proposed storm water discharge/surface water management system (MSSW system) will utilize roadside swales, perimeter ditches, catch basins, culverts, detention ponds and pump stations to manage storm water in compliance with Chapters 17-25, 40C-4 and 40C-42, Florida Administrative Code. The solid waste disposal areas will operate as watersheds, routing storm water in to the MSSW system. The retention areas have been designed to handle the retention treatment requirements of a 25-year, 24-hour "design storm" runoff, resulting from approximately eight to nine inches of rainfall. The system is comprised of three independent parts; the Class I landfill system, the Class III landfill system and the separate roadway surface water management system. The Class I system will use temporary berms to intercept storm water runoff from the cap cover system of the landfill, on top of the solid waste disposal area. These top berms will divert the storm water runoff to regularly spaced pipes which will convey the storm water into the perimeter swale located at the foot of the landfill side slopes. The runoff will then be diverted through a culvert into a concrete-lined perimeter ditch which will convey it to the pond. The top berms of the landfill also operate as erosion control features, capturing and channelling some storm water runoff away from the side slopes of the landfill, thereby assisting in erosion control. The Class I retention pond covers an area of approximately ten acres and will contain approximately 43 million gallons of water at design water levels. The peak flow of storm water runoff from a design 25-year, 24-hour storm can be accumulated and released at predetermined rates. The runoff from the first one inch of rainfall in a 72 hour period is retained and stored in the pond. No discharge will be allowed to the pond's outfall system, rather all the outfall from the runoff from the first inch of rainfall will be routed through the sand filter system prior to discharge. When storm water runoff enters the pond, it will mix with the water already in the pond and become part of the total water column. When a rainfall event then produces greater than one inch of rainfall, some water will have to be discharged from the pond by passing it through the sand filter and then discharging through the outfall structure. The water discharged is water which was already resident in the pond before the rainfall event, mixed with the current rainfall runoff from that hypothetical rainfall event. The volume of the pond is so large that storm water runoff will constitute a very small fraction of the actual water volume in the pond at any given time. On the average, it will take 33 days for a given molecule of storm water runoff to travel through the pond, the sand filter and then be discharged through the outfall system. the sand filter system operates on a water level trigger device involving floats in wet wells attached to electrical switching mechanisms. When a certain water elevation in the wet wells, reflective of the elevation in the pond, is reached, the pumps automatically start and pump water into the filter chambers, causing the water to flow over a filtering sand. The filter will be maintained periodically by lowering of the water level to permit removal and replacement of the top six inches of sand in the filter. The Class III storm water pond is similar in design to the Class I pond except that it will not use a top berm. Rather, a perimeter swale will function similarly to the Class I landfill top berm, intercepting storm water runoff from the top and side slopes of the Class III landfill. The Class III storm water pond is equipped with the same type of filtration and pumping system as the Class I pond. The Class III system is designed also to retain the first inch of storm water runoff from a "design storm" rainfall in a 72 hour period. All of that runoff from the first inch of rainfall will likewise be routed through sand filtering prior to discharge. The roadway storm water system utilizes grassed roadside swales to act as a retention structure to filter the storm water runoff. The runoff retained in the swales will be conveyed by pipe to a smaller detention and dispersion pond located between the Class I and Class III disposal areas and built with the same design constraints as the Class I pond. The roadway system will not use a pumping system to operate, but rather discharge will occur through natural action of gravity through the dispersion pond. The filtered storm water runoff from the Class I and Class III disposal areas will be discharged into adjacent wetlands after it leaves the ponds. The discharge will be performed by a wetland irrigation system. The irrigation system will discharge the filtered storm water through conveyance pipes to the wetland boundaries. There a series of perforated pipes will extend outward from the conveyance pipes themselves and serve as a means of gradually releasing the filtered storm water into the wet land area as a means of wetland replenishment and mitigation. Concerning the issue of surface water quality, it has been established that the sand filtering systems on the Class I and Class III storm water ponds are capable of providing 100 percent of the treatment required by State water quality standards when considered in conjunction with the treatment capability of the ponds themselves as natural lake systems. The individual sand filters each provide twice the capacity for treatment necessary which equates to a safety factor of 2. With both filters operating, there is a combined safety factor of 4. Although the Class I and Class III retention ponds are designed with filtration systems, the primary pollution removal system will be the ponds themselves operating as natural lakes. Once storm water enters the ponds, the average residence time is adequate to allow the biological processes of uptake and assimilation to function to remove the bulk of the pollutants, including those derived from any spillage of leachate into the storm water management system and ultimately deposited into the ponds. The volatile organic compounds which can occur in the leachate can largely be removed simply by the process of evaporation, due to the adequate retention time of any leachate- containing storm water which reaches the ponds. It has been established that, due to the storm water pond's natural treatment mechanisms, especially the long retention time, the size and volume of the ponds, as well as the vegetated sides of the ponds, that, considering also the operation of the filter system, the water discharging from the Class I and Class III storm water treatment facility will have very low concentrations of total nitrogen, phosphorous, biochemical oxygen demand (BOD), suspended solids and heavy metals. The Applicant's expert witness on water quality and water chemistry, Dr. Harper, also assumed that the Class I retention pond would have some leachate migration into the pond through groundwater influx. Worst case scenarios were used to estimate this possible influx and the results established a maximum deposition of 2.46 gallons of leachate into the pond over a 65 day period. This amount would be diluted by a factor of 14 million solely by new storm water runoff and rain normally expected under average rainfall conditions during such a 65 day period, without even considering the considerable dilution by the existing water volume of approximately 43 million gallons already in the pond in such a period. Dr. Harper's testimony is accepted. It is unlikely that any runoff can enter the retention pond on one day and then exit within one day's time through the outfall overflow device. Even assuming that runoff occurs in excess of the designed one inch, that runoff would dilute with the large volume of water already present in the storm water pond. Thus, the new storm water would be mixed, diluted and subject to natural biological processes and the process of evaporation (of volatile organic compounds), operative in the pond before it can be released through the outfall structure. The runoff will enter the pond at the west end and discharge through the opposite or east end of the pond. The majority of water caused to be discharged through the outfall because of a larger-than-design storm event runoff would thus actually be water already present in the pond as opposed to incoming runoff from the recent rain event being deposited in the west end of the pond where the storm water system discharges from the Class I disposal area. Even a rainfall event producing twice the designed-for volume would produce no effect on the water quality of the discharge. Further, along with the filter systems and the natural processes of biological uptake, assimilation as well as evaporation in the natural lake system which would operate in the pond, the side slopes of both ponds will be vegetated so as to further assist in uptake and removal of any pollutants present in the runoff, further mitigating any potential for water quality impacts. It has been established that the surface water management system is designed to segregate surface water from leachate by minimizing the size of the landfill working face and reducing the potential for storm water to contact waste and become leachate. Further, a berm will be constructed around each working face which will encompass the entire active cell of the landfill, causing any runoff water entering the working face to remain there and percolate through the landfill to the leachate collection system, rather than entering the storm water system. If a severe rainfall event could cause leachate to overflow those berms, the design includes additional berms on the interior slopes of the landfill to catch that overflow and divert it back through the leachate collection system. The berms are relocated as the working face of the landfill changes, so they will continue to fulfill these functions on an ongoing basis. In terms of a worst case event, the Applicant has also established that the estimated impact of runoff from approximately one acre of exposed solid waste entering the retention pond would still cause no water quality impacts. Further assurance of leachate segregation from surface waters is provided in a spillage control plan which would be activated in the event of leachate spillage from a tanker truck. In connection with this, any grant of the permit should be conditioned upon an adequate berm system surrounding the tank truck leachate filling device in order to contain any such spill to prevent the leachate from entering the storm water retention facilities and surface waters. Such a system should also be characterized by (and the permit conditioned upon) retention berms or other forms of containment being placed around each leachate storage tank, designed to retain the full capacity of such a leachate storage tank in the event of a catastrophic tank valve, piping or other failure. It has been demonstrated, moreover, that if the leachate-storm water separation and control system were to fail in some way so that leachate directly entered the retention pond, the volume of leachate entering the pond would have to exceed approximately 150,000 gallons to cause any water quality violation in the storm water retention pond, even assuming the high concentration of contaminants in the leachate envisioned in the opinion of Dr. Robert Livingston, the Petitioners' aquatic ecologist and toxicologist. He raised concerns that pollution of the head water systems of the St. Johns and St. Mary's Rivers might result from the operation of the project. The Applicant has rebutted the concerns expressed by Dr. Livingston and Dr. Parks and established reasonable assurances that toxins and contaminants occurring in leachate will not deposit in surface waters of the State in any significant or rule-violative amounts for the reasons expressed in the above Findings of Fact. Draw-Down Effects The Petitioners contend that there will be a draw-down of groundwater levels in surrounding wetlands caused by these storm water ponds and associated pumping, in violation of the Water Management District's rules and policy embodied in MSSW Handbook Section 10.6.3. This section presumes an adverse impact on wetlands will result if the system causes the groundwater table to be lowered more than five feet lower than the average dry season low water table. The Petitioners' expert in this area, Dr. Motz, estimated that a measurable draw-down of groundwater of one to two feet in the wetlands water table would extend outward as far as maybe 1,000 feet in all directions from each of the storm water ponds. Dr. Motz used a large error convergence factor in his calculations, however, and also used a model for a confined aquifer, which was not shown to exist at the subject site. He did not use a model which should be appropriate for unconfined or semiconfined aquifers which the evidence reveals is the more appropriate hydrogeology which would be employed in groundwater modeling for the subject site. Dr. Motz' use of a large error convergence factor can potentially result in an answer which is far from the actual appropriate draw-down figure. Numerical models are approximations of reality and the smaller the error convergence factor, then the closer to the real number of the cone of depression, or draw-down level, the model will give. Consequently, the use of an analytical groundwater, cone of depression model was shown by the Applicants' witnesses to give a more accurate result, especially in view of the large error convergence factor employed by Dr. Motz in his numerical model. It was not shown that Dr. Motz had actually "calibrated" the groundwater model he employed. The Applicants' hydrogeology expert, Don Miller, used three analytical and two empirical methods to determine radius of influence or draw-down from the storm water ponds and calibrated the models he used. Validating the data or calibrating the model is a way of making sure the model actually represents the situation intended. Calibration is performed in this instance by inputting some data and then seeing if the model itself could accurately predict the remainder of the data of interest. Using these various methods, Dr. Miller arrived at a range of radius of influence likely to occur from the Class I storm water pond of 167 feet to 184 feet at the western end of the pond and approximately 40 feet at the eastern end. The maximum radius of influence for the Class III storm water pond was shown to be approximately 160 feet at the western end and 0 at the northeastern corner. The other hydrogeology expert for the Applicant, Dr. Leve, performed a separate analytical analysis of draw-down using the Southwest Florida Water Management District's "KOCH" model to produce a projected radius of influence of approximately 167 feet, which is comparable to the projections of Dr. Miller. In conjunction with this, it was shown that Dr. Motz' use of a small value for groundwater infiltration and the large error convergence factor served to increase his predicted radius of influence in an inaccurate way. Dr. Motz also used a higher value for transmissivity or hydraulic conductivity ("K"). The Applicant's experts relied on the average of the actual permeability test results obtained for the site. A different figure for transmissivity or hydraulic conductivity results from Dr. Motz taking into account two test wells in which hydraulic conductivity could not be measured because the well water level rose too quickly to obtain a measurement. Consequently, he predicted or assumed that that factor might affect the hydraulic conductivity at the site by a whole order of magnitude, which resulted in his 1,000 foot prediction for draw-down cone of influence. The problem here is that the evidence does not demonstrate clearly that this much- greater hydraulic conductivity factor with regard to these two wells, which was an isolated incident compared to all other wells tested, is not some mechanical or human error in the installation or evaluation of the wells. Further, even if one predicts the hydraulic conductivity of the unmeasured, apparently highly conductive wells at the geometric mean of all the hydraulic conductivity measurements for the water table zone (except for the marl zone) at 3.0 X 10 cm/sec or three times greater than the value used by the Applicant, it would result in a cone of influence of 265 feet instead of 184 feet. If one also assumed a value for the two ignored wells, as data points, by assuming that they had a hydraulic conductivity value of 3.5 x 10/-3 cm/sec, the highest reported well conductivity value, and then employed that in the empirical formula used by Donald Miller, it would still not greatly exceed the 265 foot cone of depression number. No evidence was adduced to demonstrate that a cone of depression of that magnitude would have any adverse affect on the wetlands, especially in view of the recharging of the wetlands through the storm water pumping and irrigation system. In summary, the totality of the evidence in the Applicant's case, especially on rebuttal, demonstrates that Dr. Motz' methodology significantly overestimated the radius of influence for draw-down at both storm water ponds. The parties agree that the maximum draw-down of 16 feet would occur within the Class I storm water pond, where a "seepage face" would be formed where the pond would cut into the water table through earth borrowing activities. The maximum draw-down inside the Class III storm water pond, where a seepage face would be formed by the excavation into the water table to construct the pond, will be 14 feet. The lowered groundwater within the storm water ponds is due in part to the natural sloping land surface of that area and the concurrent natural slope of the water level before the ponds are even excavated. The slope of draw-down will decrease rapidly, that is, much of the 14 foot or 16 foot apparent draw-down amount will be the result of the relatively sheer seepage face formed by the pond excavation. At the top of that seepage face, the groundwater cone of depression will flatten out considerably and very rapidly so that, as the slope of the draw-down decreases rapidly in the immediate vicinity of the pond, the groundwater outside the ponds themselves will actually be lowered less than five feet. The groundwater levels used in the application were based upon seasonal high water level for the site, rather than "average dry season low" water levels, as referenced in Section 10.6.3 of the Water Management District's Applicant's handbook. Therefore, the projected draw-downs are very conservative and would overestimate the actual draw-down for dry season low water table groundwater levels. Consequently, the weight of the evidence supports the Applicant's predictions on the effects of draw-down. The evidence demonstrates that draw-down from the storm water ponds associated with both landfills will have either no impact or minimal impact on wetland species, either transitional or submerged, in the surrounding wetlands. Silvi-culture activities on the site have considerably altered the area and lowered the natural water table through the construction of drainage structures by the timber company in the past. In general, the wetland jurisdictional lines from the storm water ponds are based on United States Army Corps of Engineers (Corps) wetland criteria and thus do not contain species generally considered to be wetland species for purposes of DER dredge and fill or Water Management District MSSW jurisdictional purposes. Many species used by the Corps in determining jurisdiction, such as slash pine, can grow both in uplands or wetlands. The edges of the areas delineated as jurisdictional wetlands are dominated by transitional and upland plant species such as slash pine, gallberry, palmetto, grapevine and huckleberry, which can tolerate dry conditions. It is only as one's investigation proceeds waterward or toward the center of the delineated wetlands, (in which area the land surface slopes down- gradient at the same area where the draw-down cone of influence rapidly diminishes to an insignificant level), that the plant species change to those species adapted to regular and periodic inundation for purposes of the State agencies' wetlands jurisdiction. The draw-down maximum for any wetland location using the maximum projected radius from Dr. Miller's efforts of 184 feet, (17 feet beyond the projection based upon the Water Management District's model), is on the southwest edge of the Class I pond. Maximum draw-down there will be 24' inches at the wetland boundary line, that is, the Corps jurisdictional boundary line where the dominant plant species are transitional or upland plants such as slash pine, gallberry and bay trees. Pine trees at this point exhibit tall and vigorous growth which indicates that the water table, before installation of the ponds, is already well below the surface, otherwise these upland trees would lack sufficient oxygen to grow if water levels were closer to the surface. The potential draw-down here would thus have little effect on this vegetation. There will be essentially no draw-down effect further down-gradient beyond the DER Water Management District jurisdictional boundary, where the pines are already of diminished stature because of water existing close to the land's surface and where DER wetland jurisdictionally-listed plants predominate. The draw-down at the wetland boundary line on the southeastern part of the Class I pond will be 9 2/3 inches. Wetland species which could be affected are found 50-60 feet beyond that radius of influence at this point. The radius of influence on the northern side of the Class I pond will not cross any wetland boundary until it widens at the northwestern corner. The maximum draw-down at the wet land line near the northwestern corner of the pond would be approximately 15 1/2 inches. Here again the predominant plant species are the upland species of slash pine and gallberry and thus the draw-down will have little effect on those species for reasons mentioned above. On the western edge of the Class III pond is an isolated wetland for purposes of the Water Management District MSSW and Corps jurisdiction only. The edge of that wetland is dominated by slash pine and gallberry. The estimated draw-down on the boundary line of that land in the area dominated by slash pine and gallberry is six inches. There will be no draw-down from that Class III borrow pond area in any wetland dominated by transitional or submerged species. In addition to the above considerations and factual findings concerning the effect of the draw-down, the Applicant is proposing an irrigation systems as delineated above, which will deliver water to the wetlands to mitigate and replenish any minimal impacts of groundwater draw-down. The irrigation system will increase the degree and duration of saturation of the soils at the wetlands' boundary. This will mitigate any minimal effect of draw- down and may actually have the effect of enhancing the health and quality of the wetlands over time, from the wetlands' boundary waterward. In order that the irrigation system will pose the maximum benefit and most closely imitate the natural systems, the irrigation system will be designed for flexible operation. A wetlands ecologist will review the wetlands quarterly and adjust the irrigation system as necessary, as to location and operational regime, in order to properly maintain the health, including water levels and hydro-periods in the wetlands. The Applicant has agreed that the grant of the permit be conditioned to allow for this ongoing quarterly investigation and adjustment. Dr. Motz indicated in his testimony his belief that, to a large extent, the water pumped to the wetlands through the irrigation system would simply immediately migrate to the groundwater and immediately back to the storm water pond, through the effects of the draw-down, and not serve the purpose of replenishing the wetlands. He admitted, however, that he did not know whether the proposed irrigation system would work or not. The Applicant's expert witness in this regard, Dr. Leve, established that the irrigation system would effectively distribute water into the wetlands and saturate the surface due to the "mound effect" of water at the irrigation systems' discharge point at the wetland boundary. He used a standard, generally-accepted "mounding model" to predict the effects of the mounding for the irrigation system. Mounding is a hydrogeological phenomenon whereby water will mound up and create a zone of saturation in the soil at the point of discharge to the ground surface. Mr. Leve ran that model for a cross-section of each of the storm water pumps. He also ran the model for two different values of groundwater inputs into the ponds. A figure of 28,800 gallons of groundwater infiltration into the pond per day, as predicted by the Applicant's expert witnesses, and the 100,000 gallon per day groundwater input predicted by Dr. Motz was used. For both cross- section locations examined by Dr. Leve, the discharge of 28,000 gallons per day at the wetland boundary would raise groundwater levels by approximately three inches. The discharge of 100,000 gallons per day at the same locations through the irrigation system would increase water levels by approximately nine inches. These calculations ware based upon the discharge of the groundwater inputs into the storm water pond only. Discharge additionally of the inputs from storm water runoff from the surface of the landfill into the pond and then through the irrigation system would also be delivered into the wetlands as warranted. Additionally, a berm system will prevent surface water runoff from entering the north dirt borrow area. A berm will be constructed at the eastern boundary of the north borrow area to maintain an interior water elevation of 125 feet or one foot above the natural ground, whichever is higher. Water levels will thus be maintained at the north borrow area so that there will be no lowering or de-watering of the groundwater table. Additionally, storm water will be diverted by berms along the west end of both the Class I and Class III landfills upgradient and into the wetlands, so that the adjoining wetlands receive significant surface water recharge that previously did not flow into those wetlands. Mitigation A mitigation plan was proposed for purposes of both the dredge and fill permit application and, in the solid waste landfill application, for the MSSW permitting. It was incorporated into the draft dredge and fill permit and draft landfill permit incorporated in the Department's Notice of Intent to issue. The mitigation plan and other measures will offset the impacts from filling and other activities caused by the project in both the dredge and fill and MSSW jurisdictional wetlands on the site. The proposed mitigation measures include the creation of 4.76 acres of new wetlands; the irrigation of the wetlands surrounding the Class I and Class III storm water ponds, as delineated above, and the diversion of surface water around the landfills into the wetlands to aid in their recharge. A high quality, forested wetland will be created utilizing the reliable method of mulching and, an extensive hardwood planting program which will include red maple, sweetgum, cypress and tupelo trees. The created wetland will contain deep water and transitional zones. The area will be monitored to insure 80 percent survival of the trees planted and routine maintenance will be performed. Approval of this mitigation plan and any issuance of the permits should include the requirement that rapid replanting be done to replace any dead trees and such approval should also be conditioned on the use of the largest trees possible to be planted, by appropriate tree planting equipment, so that the beneficial uptake and filtering functions, as well as wildlife habitat functions of such hardwood wetlands can begin operating as a mitigatory factor as soon as possible. The created wetland area will replace lost wetlands with a wetland type of higher quality and potentially higher habitat function, depending upon the maturity of the trees planted (see above condition). The wetland replacement ratio attendant to the creation of this wetland area is proposed to be 2.8:1 and the permit should be conditioned on at least that ratio being observed in the mitigation wetland installation plan. Although there was some testimony critical of the wetland creation proposal because it would alter 4.76 acres of uplands which might be of significance to the wildlife in the area, in fact the site of the mitigation area is currently pine plantation which has been greatly altered from its natural state. It does not currently provide high quality upland wildlife habitat. Additionally, only 30-40 percent of the uplands on the entire tract will be altered by the entire project construction proposed. This leaves a majority of the uplands presently on the site in their current condition to the extent that it serves as wildlife habitat at the present time. A conversion of the subject area into a high quality hardwood forest wetland, which would remain bordered by upland on one side in any event, will not have any significant impact on the present value of the mitigation areas as habitat. Wetlands Assessment and Impacts Through the use of consultant personnel skilled in the fields of surveying, biology and botany, the Applicant established jurisdictional lines demarcating the boundaries of DER jurisdiction for dredge and fill permitting purposes and MSSW permitting purposes in the field and adduced evidence of those boundaries at the hearing. The jurisdictional lines established were conservative in the sense that they reflect the jurisdictional standards of the U.S. Army Corps of Engineers, which is generally landward of the lines which would be established by the plant communities characteristic of DER dredge and fill and Water Management District MSSW jurisdiction. The locations of the flags as placed by the biology-botany consultant were then professionally surveyed and plotted by a trained surveyor such that the jurisdictional line was signed and sealed as a "specific purpose of survey." Further, a biologist met with the surveyors weekly to review the plotted line to ensure accuracy. That survey was submitted to the Department in connection with the applications herein. The Department supports that jurisdictional determination in this proceeding. The Department's own jurisdictional determination staff members were on the sites of the jurisdictional determinations for approximately eight days. The location of the wetland jurisdictional line for purposes of MSSW permitting has not been challenged by Petitioners, and no evidence regarding MSSW jurisdiction has been presented by Petitioners in this proceeding. The wetlands jurisdictional survey prepared by the Petitioners, however, showed "new" DER jurisdictional wetlands which would represent, if accepted, an alteration of the DER jurisdictional wetland boundary. Additionally, the challenge to the DER. jurisdictional determination is restricted by the Petitioners to the area around the Class I landfill footprint and its associated storm water pond. No evidence has been presented regarding the jurisdictional determination for the remainder of the site and project, including the access road. Witness Don Garlic has a degree in marine biology with additional coursework and training in the field of botany, including field training in wetland species. He visited the site for seven days for the purpose of critiquing the dredge and fill DER jurisdictional line established by the Applicant and offered as proof by the Applicant in this proceeding. In the 2-3 mile segment of the jurisdictional line around the Class I landfill and associated storm water pond, Mr. Garlick opined that there were three gaps 18-20 feet wide where he did not agree with the dredge and fill jurisdictional line determination. These areas represented by the gaps, if the gaps were determined to be jurisdictional, would add rather long, linear features of putative wetlands to the jurisdictional wetlands already encompassed by the proposed Class I portion of the project. They would add approximately 1/2 acre of additional DER jurisdictional wetlands impacted by the project. The Petitioners, however, did not establish the duration of water flow at any of the areas in which dredge and fill jurisdiction was contested. Mr. Garlick stated that water was flowing each of the seven days he was on the site, from March 28 to May 8, 1991, but stated that it was raining when he was there on April 23. He did not review rainfall data to determine whether it had rained prior to any of his visits. Likewise, he was not shown to have reviewed any groundwater data or to have performed any tests to ascertain groundwater levels in relation to claiming jurisdiction over the disputed Areas A, B, C and D depicted on Petitioners' Exhibit 8. This site has not experienced a prolonged drought. For the period 1988 through the hearing, only the latter portion of 1990 reflected a significant lack of rainfall based on rainfall data obtained from the National Oceanic and Atmospheric Administration Office (NOAA) at the U.S. Navy's nearby Cecil Field, as well as the Jacksonville International Airport. Nineteen eighty-eight, in fact, had above-average rainfall of 61 inches. The Class I landfill area was originally "flagged" in September and early October 1989. July, August and September 1989 were months of above average rainfall. September 1989 had 14 inches of rain, twice the normal rainfall. Nineteen ninety had slightly less than half of its average rainfall for the year, although it started out with normal rainfall and became dry in the fall months. There has since been twice the normal rainfall for the few months of 1991 prior to the hearing. A drought of the type and duration experienced in the latter part of 1990 would have had no significant effect on the plants at the sites in question (sites A, B, C and D). They are perennial plants that remain year-round and therefore are adapted to drought and flood conditions. (T-2047) 1/ The Applicant's jurisdictional determination based upon dominant plant species, established by its consultant in evidence was based upon perennial plant species. Therefore, the hydrological conditions on the site were normal ones when these areas were originally reviewed in 1989 and the jurisdictional delineations established and the conditions found at the site shortly prior to the hearing in March through early May 1991 by Mr. Garlick were unusually wet conditions and do not reflect the normal conditions prevailing at the site. Mr. Byron Peacock was accepted as an expert in wetlands ecology and botany with a B.S. degree in each of those disciplines, with emphasis on Florida wetland species, especially with regard to Florida fresh water wetlands. Mr. Peacock is quite familiar with the site, having been to the site "dozens of times" since September 1989, almost every month for a 21-month period. Mr. Godley, another of Applicant's expert witnesses, also visited the areas put into contention by Mr. Garlick in his testimony for purposes of testifying in rebuttal and also concluded that these areas were not jurisdictional for purposes of the DER's dredge and fill jurisdiction. Mr. Mike Eaton of DER visited at least one of the areas or sites in contention and was of the same opinion. Mr. Garlick had relied on flowing water being present and the plants present to determine that Area A, a ditch along Hells Bay Road, was a jurisdictional wetland area. The areas on both sides are upland. Mr. Garlick testified that there were breaks in the vegetation in Area A and that the vegetation was sufficient to establish a connection. Area A does not contain sufficient water to support a dominance of listed wetland species under either the "a or b tests," as provided in Rule 17-301.400(1)(a) and (b), Florida Administrative Code. There is upland vegetation growing all the way across the ditch on both sides at its connecting point and point of discharge to dredge and fill wetlands. If the ditch held water it would be wettest at this point of discharge into the jurisdictional wetlands, but the ditch does not contain water on a regular and periodic basis, as established by the testimony of Mr. Peacock. Therefore, the water observed in the ditch by Mr. Garlick would have been surface water runoff from the recent high rainfall. Concerning Area B in the Class I storm water pond footprint, Mr. Garlick indicated that he relied on herbaceous wetland plants as a basis for his finding of that as a jurisdictional area. He used the "b test" vegetation method of at least 80 percent transitional plants, less than 10 percent submerged or upland species, as well as the presence of "other indicators" of regular and periodic inundation for that Area B for purposes of the rule cited last above. Area B is a logging road and lies between upland stands of planted pines. It has been used as a road within the past year and there are "rutted- out" or gouged areas in the road caused by vehicular traffic which have puddled water, but between the puddles are areas dominated by upland vegetation. There is also a clear vegetative break in jurisdiction at the point where Area B connects to the jurisdictional line at Area B's southern end. The vegetation at that connecting point is a mixture of red. root, a transitional plant and many upland species, the dominant one being amphicarpum muhlenbergianum, which looks similar to red root in the field. Mr. Garlick testified that red root was the predominant plant in Area B. Mr. Garlick may have mistaken amphicarpum muhlenberqianum for red root. He was not familiar with that upland species and did not know if it was found at the site. A review of photographs from the 1950s, 1960s, 1970s and 1980s showed that Area B had historically always been uplands. The evidence shows that this area holds water only in limited areas following rainfall and that there is no hydrological, "a or b test" vegetative connection between these areas and jurisdictional waters of the State. Area C, located on the west side of the present West Fiftone Road, also contains part of an old road bed, as well as a ditch. Area C was determined to be within MSSW jurisdiction by the Applicant, but was also claimed as a dredge and fill jurisdictional area by Mr. Garlick for the Petitioner. Mr. Garlick indicated in his testimony that plants in Area C were mixed transitional and submerged species, but were sufficient to make out the area as within DER jurisdiction, based upon those plants. He also testified that different parts of Area C met the "a test" or the "b test." The ditch on the eastern side of Area C is dominated by upland vegetation, including amphicarpum grass, slash pine and goldenrod. The slash pines growing in the ditch, as shown by a photograph in evidence, were several years old. This ditch was dry on all of Mr. Peacock's visits to the site except recently during heavy rains. The remainder of Area C is characterized by a canopy of slash pines, a subcanopy of titi shrub of an upland type, with less than ten percent of the vegetation being characterized by bay and tupelos. There is a ground cover over most of that area consisting of upland species such as chokeberry, gallberry and reindeer moss. This area was determined to be jurisdictional for MSSW purposes because of a wet area in the middle containing fetter bush and sweet gallberry, which are both transitional species for jurisdictional purposes. The entire Area C was delineated as MSSW in the permit application, even though it may not all be jurisdictional, simply for ease of delineation and survey. The MSSW wetland areas within Area C, however, have no vegetative or hydrologic connection to the dredge and fill jurisdictional wetlands. Area C thus does not contain sufficient water or vegetation under either the A or B test connected with other jurisdictional areas to be considered jurisdictional for purposes of the DER's dredge and fill jurisdiction. Area D consists of a rutted trail-road used on a regular basis by persons visiting the tract. There is an upland pine plantation on either side of the roadway. Mr. Garlick contended there was a "flow way" in Area D, but that the vegetation was spotty or sporadic. During the past 21 months, Area D was dry every time Mr. Peacock was on the site, except recently after prolonged, heavy rains. At the eastern end of Area D near its connection to Area C, there is a patch of upland amphicarpum grass, growing all the way across the ditch and road. There is also the presence of beak rush, an upland plant which looks similar to submerged rush. There is insufficient water or wetland vegetation under either the a or b test to establish that this Area D is jurisdictional. The evidence thus did not support the Petitioner's contention that additional dredge and fill wetlands would be impacted by the project. The areas claimed by the Petitioners as additional jurisdictional wetlands did not contain sufficient water to be determined jurisdictional, pursuant to DER Rule 17-301, Florida Administrative Code. These areas held water only at certain times of the year in direct response to heavy or frequent rainfall and were normally influenced, that is, fed, by surface water rather than groundwater. Likewise, these areas did not contain sufficient plant species in the canopy, subcanopy or ground cover to be considered jurisdictional pursuant to vegetation indices and procedures delineated in Rule 17- 301.400(1)(a) or (b), Florida Administrative Code. Mr. Mike Eaton of DER testified and established a 1990 DER policy embodied in a memorandum admitted into evidence explaining how the Department employs the above-cited rule for purposes of using hydric soils in making dredge and fill jurisdictional determinations. Both Mr. Eaton and the DER policy in evidence established that hydric soils are not used by the Department except as an indicator of regular and periodic inundation once "b test" vegetation has been determined to be present for purposes of the above rule. Mr. Garlick testified that he used hydric soils as a "back up" to jurisdictional determinations based upon hydrology and plants. He did not identify any area where his jurisdictional determination was based on soils alone. The Department policy memorandum in evidence emphasizes the importance, in jurisdictional determinations with hydric soils as an aid, of not merely determining whether the soil in question is hydric, but also of investigating the specific characteristics of the soil profile, which the Department maintains must be performed by a soils scientist. Mr. Carlisle, a soil scientist, visited the site and took samples of the areas indicated by Mr. Garlick. These locations were located in an approximate fashion by Mr. Garlick on Petitioner's Exhibit 8 at the hearing. Thirty-four of the 35 samples taken were determined to be hydiric by Dr. Carlisle. There are, however, breaks of up to approximately 525 feet between the hydric soils test findings in Areas A, B and D and yet the distance between one hydric and non-hydric soil test finding was shown to be approximately 50 feet. No soil samples were taken by Dr. Carlisle in Area C. These samples are found to provide an insufficient basis for determining the presence of hydric soils throughout Areas A-D. Additionally, Areas A-D did not contain areas of "b test" vegetation contiguous to other jurisdictional areas. Therefore, even if hydric soils had been present throughout these areas, these soils standing alone, without supporting "b test" vegetation, are insufficient to establish jurisdiction in the areas maintained to be so by Mr. Garlick. General Wetland Impacts This project will impact wetlands subject to the DER jurisdiction and which are jurisdictional for MSSW purposes under Chapter 40C-4, Florida Administrative Code, the rules of the St. Johns River Water Management District. Thus, a dredge and fill permit is required pursuant to Section 403.91 et seq., Florida Statutes, and DER Rule 17-312, Florida Administrative Code. Areas subject to DER dredge and fill jurisdiction and MSSW permitting jurisdiction are considered pursuant to DER Rules 17- 301 and 40C-4, Florida Administrative Code. The 1,288 acre site contains approximately 550 acres of wetland, much of which contains planted pines as well as some naturally occurring pines, as well as hardwood swamp, cypress and gum swamp, seepage slope, ditches and swales. Virtually all of the wetlands have been adversely affected in some way by the forestry practices which have occurred and are still occurring on the site. Most of the sloughs and natural flow-ways have been channelized. Ditching has drained the adjacent wetlands and significantly altered the hydrology of the entire wetland system on the site. The wetland known as Hells Bay Swamp, immediately east of the landfills, is currently being clear cut by the Gilman Paper Company. The 550 acres of wetlands are jurisdictional for either dredge and fill or MSSW purposes or both. Some 3.17 acres of MSSW wetlands will be impacted by project construction; 1.61 acres of these are also dredge and fill wetlands. The 1.61 acres of the impacted dredge and fill and MSSW wetlands consist of roadside ditches along the Hells Bay Road and a road on the north side of the Class I landfill. These roads are currently subject to logging traffic, which decreases the usage of the roadways and ditches by wildlife. Consequently, the master of species present and using these ditches is limited. In addition to the 1.61 acres of ditches, the impacted MSSW wetlands also include 0.16 acres of wetland ditches along the entrance road in proximity to dredge and fill wetlands, a 0.80 acre isolated cypress head wetland located within the footprint of the Class I landfill and a 0.60 acre wetland located along West Fiftone Road extending into the south border of the Class I landfill footprint. The 0.80 acre cypress head has already been impacted by a logging road or fire break, and ditches have been constructed through the interior of it. The larger cypresses have been logged, and the remaining vegetation is sparse, rendering it of little quality as habitat for fish and wildlife. The 0.60 acre wetland extending into the south border of the Class I landfill is an old road bed with evidence of ruts from vehicular traffic depicted on photographs in evidence. This area has a slash pine canopy and is dominated by titi shrubs, with a few black gum and traditional wetland plant species such as fetter bush and gallberry in disconnected areas. It is a low quality wetland of scant value as habitat for fish or wildlife. Prior to and during construction, as a condition on a grant of the permits, all wetlands on the site will be protected from erosion, siltation, scouring or excessive deposition of turbidity, de-watering or other construction and operationally-related impacts by the installation and use of siltation barriers placed at wetland boundaries. Because of the significant possibility of the impacts mentioned above, especially siltation and turbidity, to the wetlands during the construction phase of the facilities and attendant to ultimate operation of the landfill itself, grant of the permit should be conditioned on acceptance of monthly inspections by DER enforcement personnel once construction has begun. Wildlife and Archaeological Resource Impacts Wildlife surveys were conducted by expert witness Isaac Rhodes Robinson and members of his staff, as well as by Biological Research Associates, Inc. in the months preceding the hearing. Mr. Robinson and the biologists on his staff spent approximately 1,000 man hours surveying the site, and Mr. Robinson, accepted as an expert in wildlife ecology and wetland ecology, testified on behalf of the Applicant in this proceeding. Assessments of the site were performed by reviewing relevant literature as well as conducting field surveys for both upland and wetland species. No evidence was found of any threatened or endangered species on the site. Mr. Robinson and his staff conducted surveys in 1990 and in early 1991 and biologists from Mr. Robinson's staff were present on the site at various times from September 1989 through the time of the hearing. Surveys performed by Mr. Robinson and his personnel were conducted in accordance with Florida Game and Fresh Water Fish Commission (FGFWFC) guidelines and exceeded that agency's guidelines by surveying 100 percent of the upland areas. No testimony of any witness in this proceeding indicated any physical evidence of use of the site by any endangered or threatened species. Wildlife surveys revealed a shall colony of gopher tortoises, listed as a species of special concern by the FGFWFC in a marginal habitat zone on the extreme western boundary of the Class I disposal area. The colony consists of less than ten individuals and there will not be a significant impact to the tortoises because the individuals will be trapped and relocated to a more suitable habitat on another area of he Applicant's tract, which will be undisturbed by the landfill or its operations, or else to a suitable habitat area off-site, as directed by the FGFWFC. Jay Stephen Godley was accepted as an expert in wildlife ecology and wetlands ecology. He directed an independent assessment of the site and project's impacts. The assessment included reviewing permitting documents, aerial photographs and literature pertaining to wildlife use of the site, as well as over 90 man hours spent at the site. He confirmed that the small population of gopher tortoises was the only significant species on the site and that the project would not significantly impact any listed wildlife species. Extensive trapping and investigation of gopher tortoise and armadillo burrows reveal no evidence of listed "commensal" species, or those species commonly found in association with gopher tortoises, such as Florida mice, gopher frogs, Florida pine snakes, or Eastern indigo snakes. In additions the isolated cypress head in the Class I landfill footprint was sampled for gopher frog tadpoles, and none were found. Florida pine snakes prefer scrub or sand hill habitats, neither of which are found on the site. Pine flatwoods environments, without the presence of either sand hill or scrub habitat, like this site, are not good indigo snake habitat. No indigo snakes' shed skins or other evidence of indigo snake frequency were observed on the site. Indigo snakes are large black snakes which are active during daylight hours and easy to observe in the course of extensive surveys such as those that were conducted for purposes of this project. Considering the amount of time spent by the various biologists on the site, it is quite likely that indigo snakes would have been observed if they frequented this site. The project will have no significant impact on wading birds. All wetlands were surveyed for listed bird species for a minimum of five days using FGFWFC guidelines. No wading birds were observed on the site during the 21 month period of review by Mr. Robinson's firm. The existence of the wood stork, bald eagle or Florida sand hill crane was not established on this site and is considered unlikely by the expert witnesses, whose opinions are accepted. No eagle nests were observed and, since the tree cover provides very limited extent of open water, the site is less than satisfactory as habitat for the little blue heron, snowy egret and Louisiana heron. The only wading bird observed by the Petitioner's expert witness on wildlife issues was a little blue heron observed in a wetland area east of the site, which is off the site being purchased by the Applicant and which was recently clear-cut by the Gilman Paper Company. The project will have no significant adverse impact on the Florida black bear's habitat. The black bear is a threatened species, but black bears do not use the site. No evidence was presented that black bears have ever been present on or in the immediate vicinity of the site. No witness, including Mr. Goodowns, an employee of Gilman Paper Company who has frequently visited and worked on this site over many years, has ever observed a black bear or any sign of a black bear present on the site. Bee hives have been kept at the site since at least 1969 and, although these are very attractive to black bears, they have never been known to have disturbed the hives, nor has it ever been necessary for bee keepers to erect electric fences or other devices to protect the hives from bears. The site presently is not far isolated from human activity, which fact deters the use of it as a habitat or an occasional travel way for black bears. It is located in an area completely enclosed by I-10, State Roads 228 and U.S. Highway 301, all heavily traveled public highways, as well as in close proximity to the town of Maxville, approximately two miles away, and Macclenny, approximately five miles away. Highways with high traffic volumes are significant barriers to movements of black bears, rendering it even less likely that black bears have or will frequent the site. The only evidence of potential black bear presence anywhere near the site presented by the Petitioners was the site's position near the Osceola Black Bear Range, as interpreted from one published article, as well as indication of three bear road kills from six to 15 miles away from the site, and supposed black bear movements recorded by the FGFWFC, all represented on a hand-drawn map, only admitted a corroborative hearsay pursuant to Section 120.58, Florida Statutes. The map exhibit contained the expert's own redrawing of his interpretation of the extent of the Osceola Black Bear Range from the article he referenced, which itself was not offered into evidence. Bear movements depicted on the map really consisted of those of a bear apprehended by the FGFWF and released in the area. The map did not show any roads, therefore making location and distances to the reported road kills speculative at best. Because black bears do not use this site and because of its encirclement by significant human activity, the site is not significant as a bear dispersal corridor or travelway between the Osceola Forest bear population and the Ocala Forest population. No direct evidence by radio-telemetry data or otherwise was offered to show that black bears actually move between the Osceola and Ocala Forest populations, nor particularly that they move through the area in the immediate vicinity of the project site. Construction of the landfill would not prevent the movement or foraging of black bears through the site. Neither fencing nor presence of traffic on the landfill access roads only during daylight hours would prevent such movement. It is also unlikely that bears would likely be hit by traffic on the roads because the noisy trucks which will use the road would provide ample warning to bear's of any danger from traffic so they would avoid it. If the landfill were constructed on this site, less than one-half of 5/100 of one percent of the 3,800 square- mile area of the Osceola Black Bear Range, referenced by the Petitioners' expert witness, would be impacted. The site itself does not provide high quality black bear' foraging or denning habitat. Even the Petitioners' expert characterized it as "good" or "better than average" habitat. All but 3.17 acres of the area to be impacted by the project is upland, consisting primarily of pine flatwoods. Authoritative studies show that flatwoods are not heavily utilized by bears, which spend 70 percent of their time in swamp or wetland habitat. The 550 acres of wetlands, including approximately 280 acres of swamps, which will be left undisturbed on the site, will provide habitat and travel corridors for the black bears should any ever frequent the site. Additionally, the 4.76 acres of hardwood wetlands to be created as mitigation, would add high quality wetland habitat for black bears. Therefore, due to the extremely small area involved, the unlikelihood of use by black bears and the mitigation proposed, the landfill will have virtually no impact on black bear habitat, travelways or populations. The evidence thus established that the project will not have an adverse impact on endangered or threatened species or their habitats. Because the site has been under extensive commercial forest management and harvest operations for over forty years, the density of plant and animal life has been reduced, thus making the site as a whole, low quality wildlife habitat.
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 entered by the Department of Environmental Regulation approving Trail Ridge Landfill, Inc.'s applications for the above-referenced permits for the proposed solid waste management facility, including a solid waste management facility permit, a storm water/management and storage of surface waters permit and a dredge and fill permit, provided those mandatory conditions specified in the Notices of Intent to issue such permits, as well as those conditions found to be necessary in the above Findings of Fact and Conclusions of Law are made mandatory conditions of permitting and subsequent facility operations. DONE AND ENTERED this 20th day of September, 1991, in Tallahassee, Leon County, Florida. P. MICHAEL RUFF Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 20th day of September 1991.
Findings Of Fact Oliver DeWitt and Donald F. Richters, employees of the Southwest Florida Water Management District, were called, testified, and identified Composite Exhibit 1, the staff record of this application. Frank applied for a permit after the fact to construct a bulkhead within the mean annual floodplain of Lake Eustis. The investigation clearly revealed that fill had been placed behind a bulkhead built in Lake Eustis. Referring to the drawing marked "A" attached to the application found in Exhibit 1, the area marked in blue by the witnesses is the area filled and bulkheaded by the applicant. The applicant did not appear or present evidence to support its application.
Recommendation The Hearing Officer having considered the law and the facts would recommend denial of the application. DONE and ORDERED this 23rd day of February, 1976. STEPHEN F.

Findings Of Fact The subject application requests a permit from the Central and Southern Florida Flood Control District for the agricultural irrigation of 640 acres of grass-clover mixture, of which approximately 320 are planted annually to small grains and annual rye grass. The public notice of hearing appearing in The Orlando Sentinel Star, Orlando, Florida, and The Evening Herald, Sanford, Florida, which noticed the permit application submitted on behalf of Robert E. Lee, were received into evidence without objection. (A copy of The Orlando Sentinel Star exhibit, public notice of hearing, is attached to this report, because the original of the exhibit is contained with the report on docket no. 61, application 21423.) Mr. Lee and Mr. Wheeler on behalf of the Central and Southern Florida Flood Control District stipulated to the introduction of the application and the staff report of the Central and Southern Florida Flood Control District, without objection. It was further stipulated that the matters as contained in the application and staff report could be utilized as a basis for findings of fact and recommended order, without the necessity of putting on testimony in behalf of the applicant or the staff. Pursuant to that stipulation, oral testimony was not presented by the parties. The amount of water requested by the application is 398.9 acre/feet per year. The staff report recommended approval of 398.9 acre/feet per year, as requested by the applicant, based on the applicant's supplemental water use request. Mr. Lee did not offer any further evidence beyond the application and staff report, in support of the request for permit. The recommendation as contained in the staff report prepared by Mr. Nagendra Khanal, Hydrology Division, Resource Planning Department, Central and Southern Florida Flood Control District, was that the application #25642 for annual allocation of 398.9 acre/feet per year for purposes as applied for was acceptable. However, Mr. Khanal indicated that the permit should be subject to the following conditions: Recommendation of maximum monthly pumpage not to exceed 180.17 acre/feet or 4.70 inches/month. Pumpage in this amount is subject to availability of surplus water in the basin, consistent with and subject to specific basin rules including minimum flows and levels, all as determined by the District. Existing well and 10 inch deep well turbine pump with an installed capacity of 3,000 gpm be approved. This permit shall expire on October 15, 1978. The applicant shall install a measuring device on the well. Pumpage records shall be submitted to the District at the end of each irrigation season. There were no persons at the hearing who wished to act as intervenors in the capacity of proponents or opponents of the application, nor were there any members of the general public, not party to the proceedings, who wished to comment on the application.
Recommendation Based upon the above findings of fact and conclusions of law, it is recommended that the permits requested and the right-of-way permit be issued in accordance with the recommendations set forth in the Staff Report (attached hereto), as amended at the hearing of this cause, which amendments are discussed in the Findings of Fact herein. Respectfully submitted this 7th day of October, 1975, in Tallahassee, Florida. DIANE D. TREMOR, Hearing Officer Division of Administrative Hearings Room 530, Carlton Building Tallahassee, Florida 32304 (904) 488-9675 COPIES FURNISHED: Stephen A.

Findings Of Fact In conjunction with the preparation of plans for widening Dale Mabry Highway in Tampa, Florida, DOT in November 1985, filed a map of reservation which includes 6.49 acres owned by Petitioner. The map of reservation was filed and approved by the Hillsborough County Commission in compliance with all applicable statutes and regulations. The property in question is adjacent to the west boundary of Dale Mabry and south of the Waters Avenue intersection. The purpose of the map of reservation is to restrict building on the property for up to five years pending the filing of condemnation proceedings. DOT intends to use the area for storm water management of the runoff from the additional pacing resulting from the widening of Dale Mabry. The parent tract is 8.3 acres in size while the area encompassed within the reservation map is 6.49 acres. The entire tract is undeveloped, but to the north and south of the property along Dale Mabry Highway industrial and commercial development has occurred. The tract was acquired by the Petitioner in 1969 as an investment and has remained essentially in an undeveloped state since that time. During the period between 1969 and the present the value of the property has gradually risen until today it is sufficiently valuable to warrant development and the cost associated therewith. In the distant past most of this area in the vicinity of this property was wetlands. Prior to the acquisition of this tract by the owners, a drainage ditch, channel H, was dug through an area just west of this tract. That has had the effect of draining part of the area and has impacted on the wetlands function performed by this tract. Some dredging was done on this tract before dredge and fill laws were enacted and the area is no longer a pristine wetland. Both Channel H and the earlier demucking have caused some diminution of the property's wetlands effectiveness. No development plans have been submitted to the Department of Environmental Regulation (DER) for the development of this property. Preliminary surveys of the property conducted by DER personnel indicate approximately fifty percent of the property is wetlands and can be developed only by obtaining a dredge and fill permit from DER. Until such time as development plans are received DER will not commit itself to what developments will be permitted on land subject to DER jurisdiction. The highest elevation on this tract is adjacent to Dale Mabry highway. This area is clearly upland and can be developed without a permit from DER. The map of reservation excludes the portion of the tract running along the west Dale Mabry boundary 165 feet deep. This tract constitutes 1.81 acres (8.3 - 6.49) abutting Dale Mabry. The undeveloped tract currently performs a wetland function in that storm water runoff from the east side of Dale Mabry highway flows through a culvert under Dale Mabry in the vicinity of this property then across this property to Channel H. Similarly, storm water runoff from the west side of Dale Mabry runs south to this property thence to Channel H. Prior to selecting the Petitioner's property for ultimate condemnation to use in the storm water management program necessary for the construction on Dale Mabry, the consulting engineers on the project surveyed the area looking for appropriate sites. This site, another site at the southwest junction of Dale Mabry and Waters, and two sites east of Dale Mabry were considered. The sites east of Dale Mabry consisted of borrow pits. One was too high and would require extensive piping to transport the water to Channel H and the other already has water quality problems which could preclude water from this pit being pumped into Channel H (and from there to state waters). The property at the southwest intersection of Dale Mabry and Waters was deemed to be more valuable for commercial development and would require more development as a storm water management area than the site owned by Petitioners. Petitioner's property will require little, if any, changes to serve the intended function as a waste water management area. This will reduce the cost to DOT for so using the property. After tentatively selecting this site for storm water management the consulting engineers went to DER to obtain information on sites DER would suggest to use for storm water management purposes. DER suggested Petitioner's property and advised of water quality problems in the borrow pit. Both the Hillsborough County Environmental Protection Commission (EPC) and DER are involved in the development of environmentally sensitive areas. In 1984 the EPC advised Petitioner that one of EPC's water quality managers had stated that 85 percent of this property was developable and invited Petitioner to submit preliminary plans for developing 85 percent of the property (exhibit 2). No development plans have been submitted. Despite EPC's 1984 letter, DER exercises ultimate jurisdiction over dredge and fill permits involving wetlands and no such property can be developed exceeding that approved by DER. Accordingly, the 85 percent developable ratio used by Petitioner's witnesses is given little credence. Some three weeks before DOT filed its map of reservation Petitioner entered into a contract to sell this property for $800,000. The contract is contingent on the buyer being able to obtain the permits necessary to develop the property. Several meetings have been held between the buyer, DOT and DER personnel to discuss how the property may be developed and still serve DOT as a storm water management area. No plans for such joint use have been presented to DER. Petitioner presented one witness who opined the property was worth $1,000,000. Presumably that appraisal did not include the 1.81 acres fronting along Dale Mabry which is not included in the map of reservation. The contract to sell the property for $800,000 cash comprised the part included in the map of reservation and the tract 165 feet deep fronting on Dale Mabry. This contract which was reached in an arms length transaction indicates the price a willing buyer is willing to pay a willing seller and is a much more credible sum than is the $1 million appraisal offered by Petitioner's witness. If this witness intended his $1 million valuation to be applicable to the 8.3 acre tract, in estimating the loss to Petitioner as a result of the restrictions imposed by the map of reservation, this witness neglected to deduct the value of the 1.81 acres fronting Dale Mabry highway in reaching that calculation. This witness attempted to place a value on the loss sustained by Petitioner as a result of the inability to market the property after the filing of the map of reservation. In making this calculation he assumed 85 percent of the property to be developable and a value of $1 million. These figures are unsupported by credible evidence and the value arrived therefrom is not credible. Further, the filing of the map of reservation only restricts the issuance of a permit in connection with this property. Petitioner is free to do with the property exactly what it has done with the property since it was acquired in 1969. Although no evidence was presented that the project involving the widening of Dale Mabry in the vicinity of this property will be accomplished on a date certain, the project is scheduled to be let for bids in December 1987. Prior to commencing any work on the project condemnation proceedings for all property involved must be underway. Although this schedule is subject to change if funding is not timely provided, this is not an event expected to occur. DER requires the storm water runoff from additional paving resulting from the widening of Dale Mabry be treated before this storm water runoff is discharged into State waters. Accordingly, it is essential that DOT show capability for storm water management before this project can be approved. Section 337.241, Florida Statutes (1985), was enacted as s. 140 ch. 84-309 Laws of Florida, 1984, and amended slightly by s. 2, ch. 85-149, Laws of Florida, 1985. Some of these provisions were formerly found in s. 335.02(3) and (4), Florida Statutes. The purpose of the filing of a map of reservation is to preclude development of the property, while road construction plans are being prepared which include the use of the property, before the acquisition of the property by DOT. During construction involving the widening of US 19 in Pinellas and Pasco Counties, numerous instances arose where development of property needed for storm water management as a result of widening of US 19 commenced after plans for use of the property had been made but before condemnation of the property by DOT. This resulted in an increase in the cost of acquiring the property.
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 Whether Respondent's statements as set forth in the First Amended Petition to Determine Validity of Agency Statements Defined as Rules are rules as defined in Section 120.52(15), Florida Statutes, which have not been promulgated as required by Section 120.54(1)(a), Florida Statutes.
Findings Of Fact Petitioner alleges that the following constitute agency statements defined as rules but not properly adopted as rules by the District: The District considers a particular parcel of property to be located within a "floodway" within the District's regulatory jurisdiction for Works of the District (WOD) permitting on the basis of the parcel being located within a floodway established pursuant to a currently-approved Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The District will not accept any alternative floodway boundaries that are inconsistent with those established in the FIS unless FEMA confirms that the alternative boundaries are more accurate than those obtained from the existing FIS, and FEMA approves the alternative boundaries through a formal approval process, such as a Letter of Map Revision that also requires local government concurrence. If the District determines the parcel to be within its regulatory floodway, it will require an Environmental Resource Permit (ERP) application for any development activities within the floodway, other than those entitled to a general permit under Rule 40B-4.3010, Florida Administrative Code. The District will require an ERP for the activities described in paragraph "c" notwithstanding the fact that the Department is evaluating those same activities as part of an ERP application that has been submitted to the Department of Environmental Protection (Department) for the same activity in the same location under the terms of the Operating Agreement.1/ The District will evaluate an application to conduct development activities as described in paragraph "c" based upon the full range of ERP permitting criteria contained in the District's rules, even though the Department is processing an ERP application for the same activities pursuant to the Operating Agreement between the District and the Department. The District's policy is to deny or to object to the issuance of any permit application to conduct commercial mining operations in the WOD composed of the Alapaha River floodway. It is the policy of the District to consider any proposed development activity in a WOD, other than those eligible for a general permit under Rule 40B-4.3010, Florida Administrative Code, to have an adverse impact on the regulatory floodway, and thereby to be unpermittable by the District. The District's policies against allowing development activities in WODs apply even if a professional engineer certifies under Rule 40B-4.3030, Florida Administrative Code, that the activity will not violate the conditions of issuance set forth in the rule. The policies apply because the District will consider the development activities to violate ERP permitting rules applicable to all development activities, not just those within WODs. It is also the District's policy to ask the Department to deny ERP applications for development activities proposed in WODs that require ERPs even though the Department is processing the application pursuant to the Operating Agreement. The District's policy is to deny ERP applications to conduct commercial mining activities in WODs as determined by the FIS, and to recommend to the Department that ERP applications to the Department for such projects be denied, unless the applicant goes through the FEMA amendment process described in paragraph b to remove the area from the FEMA- determined floodway. Each party requests that it be granted costs and attorney's fees pursuant to Section 120.595(4), Florida Statutes. Stipulated Facts Angelo's is a Florida Limited Partnership, whose address is 26400 Sherwood, Warren, Michigan 48091. Respondent is an agency of the State of Florida established under Chapter 373, Florida Statutes, with its address at 9225 County Road 49, Live Oak, Florida 32060. Angelo's owns property in Hamilton County approximately four miles to the east of Interstate 75 and to the north of U.S. Highway 41, immediately to the east of the Alapaha River. Angelo's conducts commercial sand mining operations on a portion of its property pursuant to various agency authorizations, including an ERP issued by the Florida Department of Environmental Protection (Department), Permit No. 158176-001, and a Special Permit issued by Hamilton County, SP 98-3. The ERP was issued by the Department pursuant to its authority under Chapter 373, Part IV, Florida Statutes. Angelo's mining operations constitute a "mining project" as that term is used in Section II.A.1.e of an Operating Agreement Concerning Regulation under Part IV, Chapter 373, Florida Statutes, and Aquaculture General Permits under Section 403.814, Florida Statutes, between Suwannee River Water Management District and Department of Environmental Protection (Operating Agreement). The Operating Agreement has been adopted as a District rule pursuant to Rule 40B-400.091, Florida Administrative Code. Angelo's has filed with the Department an application to modify its ERP to expand its sand mining operations into an area of its property immediately to the west of its current operations (the "proposed expanded area"). Angelo's application is being processed by the Department at this time. Angelo's ERP modification application is being processed by the Department under the Operating Agreement. The District has asserted permitting jurisdiction over the proposed expanded area because the proposed sand mining activities would occur in what the District asserts to be the floodway of the Alapaha. The District asserts that an ERP would be required from the District so that the District can address the WOD impacts. It is the District's position that the District's review of any ERP application to undertake development activities in a WOD would be based upon all of the ERP criteria, and not just those criteria relating to floodway conveyance referenced in Rule 40B-4.3030, Florida Administrative Code. On or about November 30, 2001, the District published in the Florida Administrative Weekly a notice of its intent to adopt the FEMA Flood Insurance Rate Maps (FIRM) to delineate floodways for the purpose of its works of the district regulatory program. Facts Based on Evidence of Record Background/Events leading up to this dispute The total amount of the subject property owned by Petitioner is approximately 560 acres. The property is generally a rolling terrain. A significant feature is a man-made berm which was placed around the perimeter of the property by a former owner, presumably to keep water off of the land during floods of the Alapaha River. Dennis Price is a self-employed registered professional geologist. At one time, he was employed by the District and at another time, he was employed by Petitioner. For purposes of this proceeding, he was hired by Petitioner as a consultant for certain permitting projects including the project that gave rise to this dispute. Mr. Price met with and corresponded with the District as well as staff from the Department over a period of two years regarding this mining project. In June of 1999, the Department wrote to Mr. Price in response to a meeting. The letter noted that Petitioner intended to expand mining operations. In addition to informing Mr. Price of the Department's permit requirements, the letter referenced the District's permitting requirements: Mr. Still provided us with an aerial photograph showing the SRWMD's regulated floodway in the area of your mine. A copy is enclosed with the floodway line highlighted in orange. A substantial portion of your proposed expansion area will be within this floodway. The SRWMD has adopted the Alapaha River and its floodway as a works of the district. The Department adopted the SRWMD's regulations pertaining to the environmental resource permit; however, this did not include the regulations pertaining to projects within works of the district. If your permit application only includes areas outside of the floodway, a single application will have to be provided to this bureau. If you intend to expand within the floodway, a separate application will also have to be provided to the SRWMD for a works of the district permit. In either situation, the Department's Jacksonville office will review any modifications to your industrial wastewater permit. (emphasis supplied)2/ In response, Mr. Price wrote to the Department in July of 1999 and stated in pertinent part: Dear Mr. Neel, this letter is in response to your June 22, 1999 letter "RE: Permits for Mining Operation". Angelo's currently has a Sand and Limestone General Permit from DEP - General Permit Number FLA011635. That permit is based on a 5 year mining plan that was presented to the DEP on January 11, 1999. The permit, my letter and the 5 year mining plan presented to DEP are enclosed. Another attachment is an aerial photo of the property showing the Regulatory Floodway line and the location of the areas to be mined under that 5 year mining plan. The aerial photograph has superimposed upon it the location of the floodway of the Alapaha River, as determined by FEMA maps. Please note that the 5 year mining plan and the associated storage and processing areas are outside the regulatory floodway. Therefore, no works of the district permit will be needed at this time. See FAC Rule 40B-4.300(1)(a) [sic]. Future mining beyond the five year mine plan will not occur without first applying for and obtaining permits from the appropriate regulatory agency. At the present time we will only mine areas within the 5 year mine plan. We will have an engineer field locate the floodway line on the property to ensure that no mining or associated storage and process activities occur within the floodway. We are requesting that the ERP permitting process remain within the DEP bureau of Mine Reclamation since the DEP has already issued a general permit for this activity and the DEP normally handles ERP's for mining operations. We have determined that the mining area will be less than 100 acres, and based on Rule 40B-4.2020(2)(B) FAC a general permit may be applied for. We will notify you when we have a draft application prepared and would like to meet with you at your earliest convenience after that to discuss the permit application. (emphasis supplied) In response to information which Mr. Price provided to the Department, the Department wrote to Mr. Price in December of 1999 and again addressed concerns about the area of the project in relation to the floodway line: Specific Item: FLOODWAY Information submitted in response to the request for additional information (RAI) dated August 12, 1999, indicates that Angelo's proposed project boundary and activities extend up to and coincide with the Floodway Line. There appears to be no set-back or buffer from the Floodway (or any other) Line. Chapter 40B-4, Florida Administrative Code (F.A.C.), contains the rules for the Suwannee River Water Management Area which were adopted by the Department of Environmental Protection. Section 40B-4.2010(2)(b)(3)(b) provides that a General Permit may be issued for construction, operation, and maintenance of a surfacewater management system servicing a total project area less than 120 acres provided the system will not be located in, cross or connect to a work of the district. Information submitted with this (November 12, 1999) submittal indicates that the proposed activities within the proposed project coincides with, or is so closely located to, the Floodway Line so as to indicate that the proposed activities would be considered to be connected to a work of the district. This is based upon examination of the plan views and [sic] well as cross section information that has been provided. Please provide a discussion, and drawings as may be needed, that addresses all activities along the established Floodway Line. This information should address all aspects of all operations along this line through the completion of reclamation activities. Be sure to address best management practices, and any proposed setbacks in the response to this request. (emphasis in original)3/ Mr. Price described the proposed project as part of the permit application which was submitted to the Department: Describe in general terms the proposed project, system, or activity. Angelo's Aggregate Materials, Ltd. (AAM) owns approximately 341 acres of land. The current mining site, known as the Jasper Pit, is located on a 160 acre parcel of land. Of the 160 acres, only 82.45 acres are available for mining since the remainder of the property falls within the floodway boundary of the Alapaha River. The 160 acre parcel has an existing berm around the entire perimeter of the property constructed in the 1950's by the previous owner. The Alapaha flood study conducted for FEMA did not take into account this berm. AAM is proposing to construct a 20' wide access road between NW 8th Boulevard and the Jasper Pit, encompassing approximately 7.22 acres. This roadway will be constructed within the limits of property owned by AAM. The stormwater management system for the roadway will consist entirely of grassed swales as covered under FDEP's swale exemption. The Jasper Pit is a sand and limestone mining operation. (emphasis supplied) On August 28, 2001, David Still, the District's Director of Resource Management, wrote a letter to the Department in response to a request received by e-mail from the Department for technical assistance. Mr. Still responds to requests for technical assistance from other agencies as a matter of routine and as contemplated by the operating agreement between the Department and the District. The letter reads as follows: The floodway along the Alapaha River was identified and mapped as part of a Federal Emergency Management Association (FEMA) flood study performed by the United States Army Corps of Engineers, subsequently approved by FEMA and adopted as part of the local government (Hamilton County) ordinance. Based on the above, Suwannee River Water Management District (SRWMD) then adopted the floodway as a Work of the District (WOD). There is only one floodway. SRWMD recognizes and accepts the FEMA flood study performed by the U.S. Army Corps of Engineers and local government (Hamilton County) floodway boundary as the best available information to identify the floodway boundary. There is a formal process whereby change can be made to the FEMA boundary with additional or improved information. If FEMA and Hamilton County approve a revised floodway delineation and boundary, so be it, SRWMD will recognize it, however, SRWMD will not unilaterally change a boundary resulting from a detailed federal flood insurance study. We have informed Mr. Thompson and his client of this. We consider the kind of work contemplated by the applicant (at least based on our earliest discussions with them) will cause an adverse impact to the WOD (the floodway) which of course is in conflict with the requirements of 40B-400.103(1)(h) and SRWMD 40B-4, Part III, Florida Administrative Code (F.A.C.). The District will object to the issuance of any permit in direct conflict with District rules. We feel the rule is clear and any conflict with 40B-400.103(1)(h), F.A.C. which the Florida Department of Environmental Protection has adopted by reference requires denial of the Environmental Resource Permit (ERP) application. Any work of this nature within a WOD is subject to the additional permitting requirements of 40B-4, Part III, F.A.C., even if the District needs to implement such requirements with a separate WOD permit. Mr. Still's reference to "the applicant" in the August 28, 2001, letter is to Petitioner. While Mr. Still is not the agency head, his August 28, 2001, letter clearly communicates the District's policy. Given his position in the agency and the manner in which he discussed this issue, the letter describes and communicates the District's policy on what constitutes a floodway and its boundary. Mr. Still does not have final authority to make decisions on permitting within the District, as that authority rests with the governing board. In a letter written on October 10, 2001, in response to a letter from Petitioner's counsel, Mr. Still stated that District staff would recommend to their governing board that Petitioner's proposed activity is an activity within a floodway that is regulated under Chapter 40B-4, Part III, Florida Administrative Code, and that the proposed activity would adversely impact the floodway: "Therefore, as staff, we would recommend our governing board consider this activity adverse to our rules." This letter is case specific to Petitioner. Within a few days of Mr. Still's October 10, 2001, letter, Petitioner filed its Petition to Determine Validity of Agency Statements Defined as Rules. Other facts established by the evidence of record The District uses FEMA FIRM maps as evidence of the location of the floodways in the works of the district. The District communicated this policy in Mr. Still's letter dated August 28, 2001. The District will not unilaterally change the floodway delineation and boundary established by FEMA. In order for an applicant to persuade the District that a proposed activity within the FEMA floodway line is not within the District's floodway, an applicant must apply to FEMA for a map amendment or revision. The District will acknowledge that a proposed activity is not within the floodway of a work of the district only if the applicant is successful in obtaining a map amendment or revision showing that the proposed activity indeed is not within the floodway. The District has applied this policy to another company which applied for a permit. That is, the District required the permit applicant to apply to FEMA for a map revision or amendment as a condition of issuance of a permit because its proposed activity was within the FEMA floodway as established by the FEMA maps. Petitioner has not filed a permit application with the District regarding the proposed mining project. It is Petitioner's position that to do so would be futile.
Findings Of Fact The subject application requests a water use permit from the Central and South Florida Flood Control District (FCD) for use as a public water supply for an area consisting of 12,000 acres. Received into evidence without objection were the notice of public hearing appearing in The Palm Beach Post, West Palm Beach, Florida; Supplementary Report - Water Treatment Plant and Raw Water and Transfer Mains - September, 1970; Water and Sewer Rate Study, July, 1971; Water and Sewer Rate Study, January, 1972; Summary Report, Water and Wastewater Program, October, 1972; Comprehensive Report, Water Works Improvements, January, 1965; pages 20, 21 and 24 of Addendum to supplementary report filed with application; letter to J.B. Jackson from James C. Williams dated July 17, 1975; letter to Abe Krietman from John H. Klinch, dated July 31, 1975; letter to J.B. Jackson from J. Eldon Mariott dated July 22, 1975; and the Staff Report of the FCD. The application was a part of the hearing officer's file. The application requested a diversion (by way of 18 existing and 4 proposed new wells) of 12,293.2 million gallons of ground water a year and a maximum daily diversion of 33.68 million gallons for a fifty year period. The Staff Report, which is attached hereto, recommends the issuance of a five year permit for an annual allocation of 4,668 million gallons, a maximum daily diversion of 25.45 million gallons and a maximum installed field capacity of 20,000 gallons per minute, with certain conditions attached thereto. Mr. John Klinch, a consulting engineer, testified as to the contents of the application, as revised, which he prepared. It was explained that the projected number of proposed new wells did not include the possibility of failure of some of the existing wells, which do show indications of deterioration at this time. He further compared the water consumption projections for 1976 with the actual demand of the first half of 1975. Said comparison indicates that the projection was underestimated. Projected for 1976 were 9,000 meters. For the first six months of 1975, there were 8,342 meters. The projected average daily use for 1976 was million gallons. As of June of 1975, it has exceeded that at million gallons. The average per capita daily consumption in Delray Beach is approximately 240 gallons. The water consumption projection for the year 1980 is estimated at approximately 25 million gallons per day. Mr. Klinch testified that there had been no problems with salt water or chloride levels in the existing wells. The next witness called by the applicant was Louis Martin, Director of Public Utilities for the City of Delray Beach. He has never, since October of 1973, had to restrict water use, a fact which he attributes to good water management. In December of 1972 the City Council adopted a bond resolution authorizing the validation of issuance of water and sewer revenue bonds in the amount of $5,000,000.00 to expand the water treatment plant to 24 million gallons per day and to construct four new wells. The bonds were approved by the citizens of Delray Beach. Other long range plans include the engineering for the enlargement of the sewage treatment plant from 12 to 24 million gallons a day. This, together with the addition of 4 extra wells, is part of a plan whereby the City of Delray Beach would become a regional water center. Mr. Gerry Winter, a hydrogeologist with the FCD, testified that he evaluated the subject application and prepared the Staff Report in this case, and testified as to its contents. As criteria in evaluating the application, Mr. Winter looked at whether the use was a reasonable and beneficial one and whether the use would present damage to resources or other users. The limiting factor in this particular application was the danger of salt water intrusion. It was recommended that the applicant be required to replace monitoring wells, so that the FCD could obtain valid salt water interface data. It was determined by Mr. Winter that the diversion requested by the applicant would not be a reasonable use of the water with regard to the resource since the current estimate of recharge will equal discharge by the year 1980. Therefore, it was recommended that a five year permit be issued for a maximum annual diversion of 4,668 billion gallons (such amount being equal to the estimated 1980 demand - an average day demand of 12.79 million gallons - times 365); a maximum daily diversion of 25.45 million gallons; and a total maximum installed field capacity of 20,000 gallons per minute, with certain conditions attached thereto pertaining to reports to the FCD and salinity monitoring wells. Finally, Mr. Winter testified that, although his report was prepared prior to receipt of the letter from the Palm Beach County Health Department (Exhibit No. 7), the letter was reviewed by the FCD staff and it was considered insignificant to the impact of this application. Mr. Saberson expressed agreement with the Staff Report.
Recommendation Based upon the above findings of fact and conclusions of law, it is recommended that the permit requested be granted in accordance with the recommendations and conditions set forth in the Staff Report.
