Findings Of Fact On October 2, 1978, Respondent, Paul Sage, filed an application with DER seeking a permit to construct a boat ramp adjacent to his home, which is located on Crooked Lake in southeastern Polk County. Crooked Lake is a 5,538 acre meandered navigable freshwater lake. Approximately 25 percent of the shoreline of Crooked Lake has been developed into residential areas, and the remainder of the shoreline is grove and pastureland. Water levels in the lake have fluctuated considerably over the past decade. The parties have conceded for the Purpose of this proceeding that the mean high waterline of Crooked Lake is located at 120.4 feet mean sea level. Due to the aforementioned fluctuation in water level, the actual water's edge at the time of the bearing in this cause was considerably below the mean high waterline. In fact, on May 20, 1979, the water level of Crooked Lake stood at 115.5 feet mean sea level, whereas on September 27, 1978, when the drawings attached to Respondent's application were prepared, the water level was at 116.9 feet mean sea level. In any event, it is not contested that the entire length of the proposed boat ramp for which a permit is sought in this proceeding would be below the line of mean high water, and therefore on state owned land. In his application, Respondent sought a permit to construct a 12-foot wide, 4-inch thick concrete boat ramp which would extend 186 feet waterward of the mean high water line. Respondent testified at the final hearing in this cause, however, that be wished a permit which could allow construction of a boat ramp of sufficient length to allow a water depth of 3 to 4 feet at its lakeward terminus to allow launching of water craft from a trailer. Due to fluctuating water levels, the eventual ramp length necessary could be more or less than the 186 feet requested in the permit application. In preparing his permit application, Respondent made no actual measurement to determine what the depth of the lake was 186 feet from the mean high waterline, relying instead on his own estimate. The permit application does not disclose the manner in which Respondent plans to construct the proposed ramp. No detailed engineering or construction data were submitted with the application. The application form simply reflects the Respondent's intention to place 27.3 cubic yards of fill material waterward of the mean high waterline, and 6.5 cubic yards of fill material landward of that line. Although the DER permit application appraisal indicates that the ramp is to be constructed of poured concrete, that fact is not reflected in the application. Indeed, in his testimony at the final hearing in this cause, the Respondent suggested that the ramp might be constructed of poured concrete up to the water's edge, and that preformed concrete slabs would then be utilized for the remaining length of the ramp. As indicated above, there is nothing in the application form, and nothing in the record of this proceeding, to indicate what, if any, measures will be taken during construction to insure non-violation of state water quality standards. Further, although the permit application indicates that no dredging or excavation activities will be associated with this project, the Respondent's testimony at the final hearing was to the contrary. The Respondent testified that because of the slope of the land toward the lake, and his desire to construct a level boat ramp, it would be necessary to "cut" and relocate portions of the lake bottom. The exact location of these "cuts", the volume of materials involved, and the manner by which they would be removed and/or relocated are net apparent from the record. Respondent intends to construct the proposed ramp for his own personal use. He also indicated at the final hearing that he might allow neighbors to use the ramp without charge, since the nearest public ramp is approximately ten miles distant. The ramp would not, however, be used for commercial purposes. Respondent testified that he would expect to use the proposed ramp for launching his own boats approximately three times per year. Adjoining property owners on either side of Respondent have indicated that they have no objection to the granting of the requested permit. In addition, in the permit application review process, DER solicited and received comments from the State of Florida, Department of Natural Resources, and the Army Corps of Engineers. Aquatic vegetation in the area of the proposed project consists primarily of maiden cane, torpedo grass and water pennywort. This vegetation is growing within 12 feet of the water's edge as of the date of final hearing in this cause and rings the lake's shoreline to a distance of approximately 100 feet lakeward of the present waterline. Construction of the proposed project would prevent growth of rooted aquatic vegetation on 2,232 square feet of lake bottom, although some species of plants and animals might use the concrete from which the ramp would be constructed as a substrate. However, it appears from the record that no qualitative or quantitative analysis of the impact of the proposed project on the natural resources of the area was performed by the applicant. The DER representative who performed the permit application appraisal testified at the final hearing that the 12-foot width of the proposed boat ramp comprised only one-fifth of the owner's property frontage on the lake, and therefore would constitute a minimal disturbance for purposes of giving the applicant access to the open water of the lake. However, it does not appear from the record that the DER representative considered the impact of the 186-foot length of the proposed structure in arriving at his conclusion to recommend issuance of the permit. No actual measurements were made by either the permit applicant or DER to substantiate the applicant's claim that the filling of 186 feet of state-owned bottomland is necessary to furnish reasonable access from the applicant's property to the open waters of the lake. The Petitioner is an organization, composed of either persons owning property bordering on Crooked Lake, or recreational users of that lake. As such, it appears that both Petitioner and its members would be substantially affected by proposed agency action in this cause.
Findings Of Fact The Department of Environmental Regulation (hereinafter "DER") issued a letter of "intent to issue" a permit based upon an application submitted by Respondent John H. Voorhees for a weedgate and associated fences to be placed at the mouth of the Hollerich Subdivision canal in Big Pine Key, Monroe County, Florida. The majority of owners of lots in the Hollerich Subdivision are in favor of the gate. The Hollerich Subdivision canal is approximately 1,200 feet long. it is an east-west dead-end canal with its mouth facing east. Floating seaweeds, grasses and detritus (a/k/a wrack are blown into the canal by the prevailing east and southeast winds. Although some surface wrack may blow back out of the canal with the occasional west wind, the sunken weeds will not. The accumulation of windblown wrack results in a stench caused by hydrogen sulfide gas from rotting weeds. The odor causes nausea, sore throats, and sneezing. Water quality tests of dissolved oxygen (DO) taken both in April 1985 and in November 1986 show the water in the canal to be below state standards. The low DO levels found in the canal are primarily due to the rotting weeds although the nutrients leaching from the surrounding yards also contribute to those low levels. The area outside the canal is better able to diffuse and absorb the wrack problem than the area inside the carnal. Accumulations of wrack outside the canal are more temporary and therefore produce less navigational difficulty and less deterioration of water quality. The navigational problems caused by weeds choking the canal range from difficulty in steering to poor visibility. The decaying wrack also causes growth on boat bottoms, can damage boat cooling systems, and turns the water in the canal red. The amount of wrack entering the canal and accumulating there has been increasing over the last five years. The proposed structure will stop wrack from entering the canal and will function as a weedgate. The design of the gate will not cause any navigational hazards, although the weedgate should have navigational aids to assure safety. Although the weedgate will not improve water quality in the canal so as to meet state standards, it will result in an improvement. DER has no jurisdiction to resolve property disputes. The proposed weedgate is to be placed in front of the canal with no on-land attachments, and Respondent Voorhees has given reasonable assurances that the proposed gate is not on privately owned property. The proposed structure will be placed in Class III Outstanding Florida Waters. DER has balanced the positive public interest effects that will accrue to the owners of property along the canal against the' negative public interest effects that may accrue to owners of property at the mouth of the canal. Respondent Voorhees has given reasonable assurances that the project will be clearly in the public interest. Respondent Voorhees has given reasonable assurances that the proposed project will meet all applicable DER rules and standards.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, RECOMMENDED that a Final Order be entered (1), granting Respondent Voorhees' permit application and (2), authorizing the issuance of a permit subject to all permit conditions contained in the Department's letter of Intent to Issue the permit and also including the condition that no trespassing occur on the property at the mouth of the canal attendant to either the construction or the maintenance of the weedgate and associated fences. DONE and RECOMMENDED this 17th day of February, 1987, at Tallahassee, Florida. LINDA M.

Findings Of Fact The Respondent Debra Flynn has submitted an application to the DER to construct a dock extending 190 feet waterward of the mean high water line of waters of the state, which would also extend 80 feet landward of the mean high water line through a transitional wetland area. The landward extent of the dock will completely span the DER's wetland jurisdiction at the project site. A raised "pad" of fill upon which the applicant's house would be constructed and a filled driveway, although originally a part of this application, has been altered in design by the applicant such that those two items have been removed from the geographical extent of the DER's jurisdiction and those two items in the proposed project are no longer at issue. The applicant's lot is approximately 300 feet deep by 100 feet wide. This lot is one of many similarly sized lots which border Niles Channel on the east and Nyles Road on the west, on Summerland Key. These lots vary in nature from tidally inundated mangrove wetlands to a combination of upland and transitional wetlands fringed by mangroves along the water's edge. The portion of the applicant's lot nearest to Nyles Road is primarily characterized by upland vegetation extending approximately 75 to 100 feet in an easterly direction from the road. The elevation gradually decreases toward the waterfront of the lot on Niles Channel, with buttonwood (Conocarpus erecta), dropseed (Sporobolus sp.), key grass (Monanthochloe littoralis), and sea daisy (Borrichia sp.) being the dominant species over most of the applicant's lot. Over the northern side of the property adjacent to adjoining lot 34, a pocket of black mangroves (Avicennia germinans) extends inland, nearly to the upland area described above. As the lot elevation drops toward the shoreline, mangrove growth occurs more frequently, culminating in a dense mangrove fringe bordering Niles Channel. This mangrove fringe becomes well established some 30 feet landward of the approximate mean high water line, being dominated by black and white mangroves. Waterward of the mean high water line, red mangroves dominate for a distance of approximately 30 feet out into Niles Channel. The landward portion of the dock would have only minimal environmental impacts on the transitional wetlands as established by DER's expert witness Meyer and witness Kephart. No contradictory evidence was submitted in this regard. The bottom of Niles Channel extending 65 feet waterward of the mangrove fringe area is characterized by a hard caprock substrate covered with somewhat coarse sediments and loose algaes. In addition to the loose algae, the bottom, attached marine life communities are characterized by red, brown and green algae, sponges, anemones and hard corals. Waterward of this initial 65 foot zone, a relatively narrow zone of seagrasses is encountered. This zone of seagrass extends about 15 to 20 feet in width, forming a somewhat broken, noncontinuous band extending from north to south across the front of the property. Within this seagrass band, the primary growth is turtlegrass (Thalassia testudinum). There are smaller amounts of Cuban shoalweed (Halodule wrightii). Continuing waterward of this seagrass growth, the vegetative bottom coverage decreases with sandy patches becoming larger and more frequent. The bottom profile also becomes more rough and irregular, characterized by the presence of dissolved limerock holes as well as outcroppings. These holes and outcroppings provide excellent habitat for shelter-dependent fish and invertebrate species, such as spiny lobster and stone crabs. The area constitutes-prime nursery habitat for spiny lobsters and stone crabs. Water depth where the dock, as originally proposed, would terminate, which is in the area of the lobster and crab habitat, is approximately one and one-half to two feet deep at mean low water. The dock as presently proposed would extend some 30 feet beyond that area, or about 160 feet from the waterward edge of the shoreline mangrove fringe, or 190 feet from the mean high water line. Thus, the dock as presently proposed would terminate in a flat or sandy area which is somewhat deeper or about two to two and one-half feet deep at mean low water. Termination of the dock at that point, with boat traffic involved with the dock beginning and ending at that point will result in less likelihood of damage to the lobster and crab and other more fragile marine life habitat which occurs landward of the 190 foot termination point. At this point, the dominant marine species are patchy growths of red algae (Laurencia sp.). These growths are less susceptible to damage from prop-wash and wakes of boats than are the more landward areas characterized by turtlegrass, Cuban shoalweed and the "hole and outcrop" nursery habitat area for fish, lobsters and stone crabs. The physical and biological characteristics of the water bottom at this 190 foot distance offshore are more compatible with boat usage. The bottom here is characterized by hard caprock close to the surface, with a shallow overlying layer of inorganic, coarse-grained sediment consisting primarily of pulverized rock. There are very little or no seagrasses at this point. The applicant's boat draws approximately 12 inches of water underway and 18 inches at rest, and the dock is for the private use of the applicant only. The water depth at the termination point of the dock effectively precludes the applicant from navigating to and from the proposed dock with a significantly larger, more powerful boat and thus the physical characteristics of the water depth and hard bottom existing at the dock site themselves effectively limit the likelihood of harmful prop scouring or boat grounding damage. Impacts on water quality caused by the installation and operation of the proposed dock to the extent of its use by the applicant's private boat only, will be minimal. Some turbidity and disruption of marine life will inevitably occur during construction, but this will have no serious impact on either water quality or marine resources. The dock, as it is proposed to be constructed, will be at least three feet above mean high water level. It will be sufficiently narrow in width so as to preclude significant shading of seagrasses from sunlight and resultant death or damage to the seagrass beds between the end of the dock and the mean high water line, such that no water quality violation or harm to these marine resources will ensue. The proposed construction will not eliminate valuable marine resources in Niles Channel and will have no immediate or long-term adverse impact on the quantity or quality of the State's natural marine resources through the loss of habitat in the Niles Channel area involved. Because of the varying amounts of wetlands encompassed in the lots in the Niles Channel subdivision, it is unlikely that all of the lots in the area will be developed, or that a great number of docks similar to the proposed dock will be constructed. The Petitioner's expert witness, Mr. Robertson, established that less than half of the lots in this subdivision are suitable for or likely to be developed. The Petitioner's own witness, Fahrer, also established that Monroe County is planning to restrict development in this area through their zoning power. Accordingly, there is no reasonable expectation that many similar docks will be constructed in the Niles Channel area. Further, the recent amendments to the DER's organic statutes and related rules which took effect on October 1, 1984 mandate consideration of additional restrictive criteria involving effects of such projects on wildlife habitat, which will further serve to restrict development along the shoreline in this area. The shoreline in this subdivision is essentially undeveloped, with only one other dock presently in place, which is longer and extends further into Niles Channel than does the proposed dock. Although there was testimony by witnesses for Petitioner that the proposed dock would entail bone fishermen having to navigate out and around the dock, this testimony does not establish the premise that the dock will pose a serious impediment to navigation. The proposed dock may add slightly to the disruption of some recreational fishing navigation, however, since the adjacent property has the longer dock already in place, any disruption caused by this proposed shorter dock will not be significant and will not be contrary to the public interest in terms of navigation impediment.
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 the State of Florida, Department of Environmental Regulation grant the application of Debra Flynn for a dock construction permit in accordance with the conditions delineated above.

Findings Of Fact On March 12, 1985, Applicant filed a request with the Department for a permit to construct a marina in a manmade basin (Captain's Cove) located on Lower Matecumbe Key, Monroe County, Florida. The permit sought by the Applicant, as modified, would allow it to construct a 52-slip docking facility consisting of two 5' x 248' docks, each with fourteen 3' x 40' finger piers and twelve associated mooring piles; and, approximately 590 linear feet of riprap revertment requiring the disposition of approximately 300 cubic yards of rock boulders landward and waterward of mean high water (MHW). All docks and finger piers would be constructed of prestressed concrete supported by concrete piles; mooring piles would be pressure treated wood. The Applicant proposes to organize the facility as a condominium development; however, live-aboard use will be prohibited. A manager's quarters, office, restrooms and a parking area will be provided on the adjacent uplands. The Department's October 3, 1985, notice of intent to issue, proposed to issue the requested permit subject to the following condition: The permittee is hereby advised that Florida law states: "No person shall commence any excavation, construction, or other activ- ity involving the use of sovereign or other lands of the state, title to which is vested in the Board of Trustees of the Internal Improvement Trust Fund or the Department of Natural Resources under Chapter 253, until such person has received from the Board of Trustees of the Internal Improvement Trust Fund the required lease, license, easement, or other form of consent authorizing the proposed use." If such work is done without consent, a fine for each offense in an amount of up to $10,000 may be imposed. Turbidity screens shall be utilized and properly maintained during the permitted construction and shall remain in place until any generated turbidity subsides. Only non-commercial, recreational boats shall be allowed to use the proposed marina. The applicant shall incorporate this condition into the condominium document for the proposed marina and supply the Department with a copy of the document prior to any sales of the condominium. No live-aboard boats shall be allowed in the marina. This condition shall also be placed in the condominium document. A portable sewage pumpout wagon shall be provided at the marina. Pumpout effluent shall be properly disposed of by methods acceptable to the department; these methods and locations shall be approved by the department prior to construction. A supply of oil absorbent materials, designed to clean up small oil spills, shall be maintained at the marina office. At least sixty (60) days prior to construction, the applicant shall submit to the Punta Gorda DER office for review, a detailed list of equip- ment to be permanently maintained on site. This list of equipment shall be modified as necessary and approved by the department prior to construction. The uplands on the permittee's property shall be graded to direct stormwater away from the edge of the boat basin. No fuel facilities nor storage shall be allowed at the project. Only clean rock boulders free from attached sediments or other deleterious compounds, and of a minimum diameter of 2' or greater shall be installed as riprap. 1O. The Marathon Department of Environmen- tal Regulation office shall be notified 48 hours prior to commencement of work. "IDLE SPEED-NO WAKE" signs shall be placed at conspicuous locations at the docking facility with additional language that "this precaution exists throughout the length of the canal channel during ingress and egress". At least two trash receptacles shall be provided on each of the two main walkway piers: these receptacles shall be routinely maintained and emptied. Prior to dockage use by boats, marker buoys shall be established around all vege- tated shallow zones within the limits of the submerged property limits with signs advising boaters of "SHALLOW WATERS-NO ENTRY". Prior to construction, the applicant and the Mara- thon DER office shall meet to discuss accept- able locations for these markers. The project shall comply with applic- able State Water Quality Standards, namely: 17-3.051 - Minimum Criteria for All Waters at All Times and All Places. 17-3.061 - Surface Waters: General Criteria 17-3.121 - Criteria - Class III Waters - Recreation, Propagation and Management of Fish and Wildlife: Surface Waters. The Applicant has agreed to comply with all conditions established by the Department. The Marina Site Captain's Cove is a manmade navigable lagoon with access to Florida Bay through a 2,500' long by 100' wide canal located opposite the project site. The waters of Captain's Cove and the canal are designated Class III surface waters, and those of Florida Bay as Outstanding Florida Waters. The controlling depth for access to the proposed marina is found at the mouth of the canal, where Florida Bay is approximately 6' mean low water (MLW). Depths within the canal are typically 1' or 2' deeper than the controlling depth at the mouth. Captain's Cove is roughly rectangular in shape. It measures 1,400' northeast to southwest, and up to 500' northwest to southeast. In the vicinity of the Applicant's property, which is located in the northeast fifth of the cove, the cove measures 350' wide. The bottom depth of the cove is variable. The southwestern four-fifths of the cove was typically dredged to a depth of 25' MLW. Within the northeast fifth of the cove (the basin), a gradation in depths is experienced. The northwest portion of the basin, located outside the project site, is typically 5' - 6' MLW, and heavily vegetated by sea grasses (turtle grass, manatee grass, and Cuban shoalweed). The southeast portion of the basin, which abuts the Applicant's property, consists of a shallow shelf 10' - 20' in width. Beyond this shelf, the bottom drops off steeply to a depth of 20' MLW. The shelf abutting the Applicant's property is sparsely vegetated with mangroves, and provides limited habitat for aquatic fauna such as domingo mussels and paper oysters. Replacement of these mangroves and other shoreline vegetation with riprap would not significantly affect the biological balance within the cove and would provide suitable habitat for existing species. The waters within the cove are quite clear, and meet the Department's water quality standards except for a thin layer at the deepest part of the cove where dissolved oxygen violations were noted. The proposed marina is, however, to be located in the northeast fifth of the cove, opposite the access canal, where the waters are more shallow and water circulation more prevelant. As sited, the proposed marina will not exacerbate or contribute to a violation of the Department's water quality criteria. Areas of Concern During construction of the marina elevated turbidity may be expected by disruption of the basin sediments caused by installation of the facility's pilings. This can be adequately controlled, however, by the use of turbidity curtains during construction. Shading of the benthic environment is a long term impact associated with marinas. Since the boat slips will be located in the deeper 20' MLW depth of the basin, where seagrasses are not present, sunlight will be permitted to reach the productive areas of the basin lying at 5' - 6' MLW and no adverse impact from shading will be experienced. Boats by their very existence and operation present potential negative short term and long term impacts to the environment. Potential damage to the seagrass beds in the northwest portion of the basin will be eliminated or minimized by the planned installation of buoys and/or signs prohibiting navigation in that area. Potential damage from wave action generated by boat operation will be eliminated or minimized by designating and posting the marina and access channel as an "idle speed-no wake" zone.[footnote 1] [footnote 1: Intervenors raised some concern regarding possible impact to the Florida manatee. While manatee have been sighted in the access channel, their occurrence is infrequent. Marking the shallow areas and designating the area as an "idle speed-no wake" zone will provide reasonable assurances that the manatee will not be adversely affected by the proposed marina.] The fueling of boats, hull maintenance, boat cleaning (detergents), and sewage discharge are additional pollution sources associated with marinas. While the proposed marina will have no fueling facilities and no live-aboards will be allowed at the marina, additional conditions must be attached to the permit to eliminate or minimize potential impacts from these potential pollution sources. In addition to the conditions established by the Department, the following conditions are necessary: All craft docked at the marina shall be prohibited from pumping sewage into the waters of the cove. Use of the boat slips shall be limited to those person(s) who own the slip. Leasing of boat slips shall be prohibited. Living aboard any boat docked at the marina is prohibited at all times.[footnote 2] [footnote 2: During hearing some concern was raised regarding the definition of live- aboard. The Department's intent in specifying no live-aboards was that no person(s) stay overnight on any boat moored at the marina. The purpose of this condition is to clarify that intent.] No boat cleaning, hull maintenance, nor fish cleaning shall be allowed at the permitted facility. Limiting use of the boat slips to owners will provide reasonable assurances that the conditions imposed on the requested permit will be complied with. Prohibiting live- aboards, the pumping of sewage, fish cleaning, boat cleaning and hull maintenance, will provide reasonable assurances that Department standards for bacteriological and water quality will not be violated.
Findings Of Fact In September, 1985, Armand J. Houle purchased an 80 acre tract located eight miles east of the Naples toll booth on State Road 84 and approximately two miles north of Alligator Alley. The purpose of buying the property was to mine the limestone rock thereon, through a borrow pit, for the purpose of selling it as road base to the State of Florida Department of Transportation for use in the construction of 1-75 (Alligator Alley extending from Naples to the Florida east coast). While no contract has existed or currently exists, correspondence between the Department of Transportation and counsel for the Petitioner indicates that approximately 800,000 cubic yards of fill will be required in the immediate area and that Petitioner's proposed borrow pit would be the ideal source of this rock. Prior to making the purchase, Mr. Houle's associate, Raymond Chester, contacted both the Department of Transportation concerning the potential use of the rock and representatives of the Department of Environmental Regulation. The response he received from these agencies led him to, believe that a borrow pit might well be permitted and the effort should be pursued. After Mr. Chester and Mr. Houle became partners in the property, they contacted county officials and received zoning and other local permits for the facility. It was only after this, when DER was approached again that the applicants were advised a permit would not be issued. Mr. Houle agrees that, if the permits as requested were granted, he would accept a prohibition against further development of the property after removal of the rock and fill, would allow access to the restored lakes to the public for fishing and recreation; would agree to an appropriate restoration plan for the site; and would ensure compliance with the restoration plan stipulated by the Department. After the property was purchased in late 1985, Mr. Houle approached Daniel W. Brundage, the vice-president of an engineering firm in Naples, with a view toward developing the property in question as a borrow pit. Plans were developed for application for permits with the County and Mr. Brundage, consistent therewith, visited the site on several occasions. He found some vegetation off from the site which could be related to wetlands and contacted a representative of DER with whom he went to the site to look it over. This agency representative, Mr. Beever, concluded that the property was a jurisdictional wetland. Mr. Brundage nonetheless felt confident enough to begin work with the County to secure a permit to convert this land, classified as agricultural, to mining property. Consistent with his efforts, the request for conversion went through a four step process on the way to the County Commission which included approval by (1) the Water Management Advisory Board, (2) the Environmental Advisory Council which recommended same changes accepted by the Petitioner, (3) the Subdivision Review Committee, and (4) the Coastal Area Planning Council. All four subagencies recommended approval and thereafter the County granted its permit for work to begin. Assuming all permits are issued, the property will be developed in two stages. In stage one the site will be cleared of vegetation, and the top soil on Phase I, the western 40 acre parcel, removed and used to construct a berm around the entire perimeter of the site as well as between the two 40 acre parcels. The berm will be entirely within property boundaries and used to isolate any water removed from the active phase within the site so that it does not flow onto adjoining property. The eastern 40 acre tract, (Stage II) will be used for water storage during the excavation of Stage 1. It is anticipated that no water will leave the site during construction of either stage with the exception of extraordinary waterfall during rainfall or hurricane. Before any water is discharged, it will go into a storage configuration so that any sediment therein would settle to the bottom before discharge. The discharged water will be filtered through hay bales or filter screens to avoid any turbidity in the surrounding water. The design of this holding capacity in the filter system is sufficient to accommodate the water of a 25 year storm. As Stage I is completed, Stage II will be opened, and the ground water from Stage II pumped back to Stage I for storage. A similar storage and filtration system will be utilized around Stage I. Primary access to the property will be along the western boundary of 8 Mile Canal, but if this is not allowed, Petitioner proposes to build a single span bridge across the 8 Mile Canal at 40th Street to allow access to the property. After the lime rock has been excavated, the berm will be removed and the side of the property graded to form the banks of a 56 acre lake for recreational purposes. The edge of the lake will be a meandering slope at a ratio of 10:1 which will be assured by survey to be in compliance with the County plan. The lake, which will have a maximum depth of 20 feet, will be excavated at a depth ratio of 2:1 from the edge of the slope to the bottom of the lake. During excavation and prior to restoration, heavy equipment will be used for the removal of the rock such as drag lines, back hoes, motor graders, and bulldozers and an area within the boundaries of the site will be isolated and set up for fueling and maintenance. It will be floored with a membrane to prohibit oil and fuel from getting into the ground as a result of accidental spills. Storage tanks for fuel and oil will be above ground and available for immediate inspection. Waste facilities will be in the form of porta-potties and any water falling in this maintenance area will be drained to a low sump within the membraned area for storage until evaporation or safe removal. In the event of a heavy rainfall, water can be stored and anti-sedimented and cleaned and, if necessary, operations can be temporarily stopped. Mr. Brundage indicates that he has never seen any standing water on the site during his five visits nor has any standing water ever been reported to him. He is aware of no historical or archaeological sites on the property, and at no point would rock be mined within 50 feet of the property line. Dr. Durbin Tabb, a botanist, was retained by the Petitioner to prepare a plan for restoration of the site after mining operations were complete. In preparing his plan, he visited the site on several occasions finding varying plant life, much of which was grasses and rushes. In the north was a pine lowland where he saw palmettos scattered in the grassland as well as a few dwarf cypress trees. He also observed a small cluster of cabbage palms in the southern portion of the eastern tract and noted that the currently existing berm along the eastern boundary of the eastern tract is currently being invaded by exotic plant life including the Brazilian pepper. Dr. Tabb found little evidence of recent surface water accumulation; mollusk residue showed no evidence of recent viability; and he found no crawfish burrows which, if present, would show a water table near the surface. Other visitors to the site, however, did find crawfish burrows. The marsh soil shows that, at some time in the past, it was wet enough to support a soil-forming community. This is no longer' the case according to, Dr. Tabb. The process was stopped by the formulation of the Golden Gate Canal System in the 1960's. The existing marsh does, however', hold sufficient water to support the growth of muhli grass. Dr. Tabb's restoration plan is his best estimate of how the property can be restored to its previous condition by replanting native species found in the area. The program will include littoral zone vegetation to provide shelter and a feeding zone along the water's edge which does not now exist. The plan calls for the saying of the marsh soil. Since neither DER nor the client responded to his plan, when submitted, with any suggestions or corrections, he assumed it was approved. Dr. Tabb, who is also an expert in estuarian biology and zoology, concluded that the area on which this site is located is a very poor habitat for deer and panther. The red cockaded woodpecker has no trees on the property which it specifically desires and the property is a poor or nonexistent habitat for the indigo snake and the Everglades snake. It might, however, constitute a habitat for the Cape Sable seaside sparrow, but this bird has never been seen in this inland area. Panthers cross the area as do bears, but the presence of the excavated lake would be no more hindrance to them in their crossing than would the presence of Alligator Alley and the proposed 1-75. The area with sawgrass and muhli grass, which is dominant throughout the Golden Gate area, is called a "dry prairie" as opposed to a "wet prairie." While some of the same plants exist, it is somewhat different in that there are no viable wetlands wildlife organisms currently existing on the property. In Dr. Tabb's opinion, the property has lost its wetlands characteristics and only the marsh soil's water retention permits the life of the grasses currently existing. Wading birds would use the site later but do not currently utilize the area where excavation would take place. In Dr. Tabb's restoration plan, the slope to the lake would be replanted with saw and muhli grasses down to the litoral zone. From there on to the water, a palette of normal wet grasses would be planted to serve as feeding sites and roasting sites for the birds. In addition, an island planted with willows would be constructed off shore in the lake. Deer currently visit the area. They are not currently supported on the land though Mr. Barnett, of the Game and Fresh Water Fish Commission, indicated that they come out of the pine flats at night to feed on the grasses on the prairie. These deer form a large portion of the food chain for the panther, and Dr. Tabb does not consider it conceivable that the project, replanted and restored, would in any way adversely impact the Florida panther or the birds in issue here. In Dr. Tabb's opinion, it is questionable whether the site comes under the jurisdiction of DER based on the grasses present because he cannot find the water connection to confer jurisdiction. Dr. Tabb has not seen standing water on the site as he has seen on two other sites within the area where DER has granted permits for rock pits. On a site like this, the vegetation changes with the seasons. This site is not now connected to the canal along Alligator Alley by vegetation. There may have been a vegetation connection in the past, but as one goes up toward the site from the canal, the grass changes gradually from low pineland grasses found on higher ground to the lower sawgrasses found on the site in question. In Dr. Tabb's opinion, if Mr. Houle's property is to be considered a wetland, it is a transitional wetland. Turning to the issue of loss of habitat, if one assumes that portion of the property that will be converted to a lake will be denied to the panther, this is not the case for the deer which, in this area, is considered to be aquatic. Any denial of the lake area would constitute a very small negative impact compared to what is going on in other areas of Collier County. Admitting that there is a requirement to consider the cumulative impact of a project, in Dr. Tabb's opinion, this project would constitute a "may impact" situation. There is no definitive evidence as to what would happen, and he would be more concerned if the area were now a good panther habitat. It is not, however, and in fact it is no more than a habitat for the grasses which grow there. As to the wetlands issue, the only sign of exotic plant invasion is in the disturbed area around the canal which was installed approximately 18 years ago. The absence of these exotic species is, in Dr. Tabb's opinion, a clear indication that there is no flowing or standing water since the site is too dry for the germination of the seeds. There will be some removal of the biomass by the excavation of the lake. This biomass, consisting of grass primarily, is consumed by fire every year or so and insects eat it as well. Admittedly, some of the biomass is being eaten by animals of some nature and that which is converted to a lake will be removed. There is a trade-off, however. Dr. Martin Roessler, a marine biologist, prepared a report, on the water quality of the adjacent 8 Mile Canal, and other water bodies in the area. In preparation of his report, he took water samples in the areas in question, read literature on the water quality in the area, and looked at water quality data provided by U.S. government agencies and private companies. On the several visits he made to the site, he has not seen any surface water. The first time he could get water only in the adjacent canal, and he also got some water from the land borings done by Dr. Missimer on the site. Dr. Roessler is familiar with State standards for water quality and, in his opinion, the turbidity standards would not be disturbed because there was no water on the ground to be sheet flow. All water was at least three feet underground and, in addition, Petitioner has agreed to properly sod or otherwise treat the berms he will build to prevent erosion and any resultant turbidity either off-site or in the 8 Mile Canal. Dr. Roessler also does not believe the project would violate the oil and grease standards. There is nothing inherent in the mining process to bring into play oils and greases except for the possible problem in refueling and maintenance operations. In that regard, Petitioner has shown how he will provide against that by placing a membrane to prevent any oil, grease or other contaminant from getting into the ground. This area does not contain the organic mulch which produces natural oils and greases. The water near the surface of the lake will contain sufficient dissolved oxygen to meet State standards without problem. In the summer months when the dissolved oxygen count is low, generally, the lake bottom water may not meet State standards, but that happens quite frequently, naturally, across the entire area. Dr. Roessler believes that the dissolved oxygen requirements of 2.5 at the surface and .5 at the bottom will most likely be met in the lake created by this project. Concerning the biochemical oxygen demand (BOD), he concludes the operation in the quarry will not artificially decrease the available oxygen below the required amount. The BOD demand in this area would not be threatened by the lake. As to the iron standard and other toxic substances, Dr. Roessler does not believe that the project will create a violation of the standard nor will any runoff increase dissolved iron in adjacent waters. Hydrogen sulfide and pharasulfide standards will similarly not be violated. Sulfides are found only in trace amounts, if at all, in natural waters. In deep limestone lakes the chemical structure is not conducive to the formation of the acidic compounds. In short, Dr. Roessler believes the water in the mine would be very similar to that found in other rock quarries in the area. These lakes are a dominant portion of the recreational fresh water fishing availability. This instant lake also will, in time, upon development of the food chain for the fish, become an equivalent fishing habitat. Dr. Roessler concurs with Dr. Tabb regarding the flora on the site, which he observed himself. This site is 15 to 18 miles from marine or estuarian waters and to reach them one would have to go down a series of canals and past a saline dam to the coast. Any runoff from the site in question would have, if any, a minuscule effect on marine waters. This site was originally a wet prairie which was drained by the Golden Gate Canal System. As such it is a relatively poor habitat for life forms generally found in cypress wetlands. Creation of this lake will, in the opinion of Dr. Roessler, enhance the game, fish, and recreational activity of the area. It would be a benefit to the animal population to have a water source for drinking during drought. There would be no adverse effect on public health, safety or welfare. Turning to the major issue of water, Dr. Thomas Missimer, a hydrogeologist specializing in ground water, visited the site, examining the canal on the east side, and the soils and rocks exposed. He took soil borings and examined the site hydrology to see what fluctuations occurred in the water levels due to rainfall. Mr. Missimer, took numerous readings from September 18 through November 5, 1987 during a period of wet weather including a tropical storm. He carefully compared the site geology to other sites he had studied and compared the flow of water through the soil. He compiled existing information on chemistry in the streams in the area to see what the natural conditions were. He looked at other man-made lakes in the area which were previously borrow pits. As a result of his studies, he concluded that the groundwater level throughout the entire period never got higher than three feet below the land's surface and often was five feet below. During the previous July through September, 34 inches of rain fell in the area which was, in his opinion, average to above average. There is some evidence, however, to indicate that rainfall in the area was approximately 33 percent below average during the period. Nonetheless, Mr. Missimer took a measurement the day after a tropical storm had deposited three inches of water on the land. The water level at that time was still three feet below land level, and there was no standing water. Both the three foot and the five foot level are well below the top of the berm sloped at 10:1 as is proposed in the restoration plan submitted by Dr. Tabb. This site has, from a hydrological standpoint, been greatly affected by the installation, of the 8 Mile Canal and the canal system to the north. As, a result of this activity, standing water has not existed for many, years since the dredging of those canals. If de-watering is a necessary portion of the mining plan, any waters removed thereby would be retained in the impoundment area described by Mr. Brundage and switched back and forth. As proposed, the plan can completely avoid any impact to off-site property by water runoff. Construction of the pit and the lowering of the water level thereby will not have a major impact on the groundwater in the surrounding areas. Any effect would taper off as the distance increased from the site and would be of little significance. This proposal would also have little, if any, impact on groundwater quality. In Mr. Missimer's opinion, water quality is currently good and will stay good. This type of rock mine is very common in the area incident to construction. Some have been used as a source of potable water by The City of Naples; by Deltona Utility Company for Marco Island; and the south area of the County. These resources are still being used. There is little difference between those currently being used as potable water sources and the proposed lake here. Mr. Missimer also indicates the project will have little impact on the sheet flow of water. Sheet flow no longer exists here because of the canals and roads already existing. If there were a sheet flow created by a very heavy rain, this pit would have no impact on it. The water level in the lake will be approximately the same as exists in the ground currently and in the 8 Mile Canal. There should be no shoaling in the canal due to the project, and the presently existing spoil bank on the west side of the canal already prevents flow into the, canal from this land. If this pit is properly constituted and maintained, and if proper mining procedures are followed there should be no effect on the 8 Mile Canal to the east or the Alligator Alley Canal to the south. There is no surface water connection currently existing between this site and either canal. As to the issue of dissolved oxygen, the currently existing groundwater on the site and in the surrounding area has little or no dissolved oxygen in it. Water coming into the lake will be groundwater low in dissolved oxygen, which is identical to the water which currently goes into the canal system. The canal gets very little oxygen from the wind because it is so narrow. The lakes to be constructed, on the other hand, will get a large amount of oxygen from the 56 acres of water exposed to the open air. Consequently, construction of the lakes would increase the dissolved oxygen content of the water in the area, at least in the lakes, down to a level of several feet. This is a positive factor. Mr. Missimer recognizes, however, that during the dry seasons, when the lake is fed solely by groundwater generally low in dissolved oxygen, the lake water which has been converted to surface water may fail to meet the Department's surface water standards for dissolved oxygen. Warmer weather generally results in lower dissolved oxygen readings and, admittedly, Respondent's readings were taken in December when the dissolved oxygen levels are higher. As a result, the comparative samples which were taken in December are not necessarily indicative of what will be the situation in the lake, year- round. Respondent's witnesses present a more dismal picture of the effect of Petitioner's proposed project. Mr. Bickner, an Environmental Supervisor with DER's Bureau of Permits and himself an expert in water quality, zoology, and ecosystem biology, first became involved with this project while the permit request was being processed in late 1986. This application was a standard form project because of the quantity of material to be excavated. As a part of his processing, Mr. Bickner requested evaluations of the project from other agencies and divisions within DER and, on the basis of his personal evaluation and the recommendations he received, concluded that the application was not permittable. He recommended it be denied. Mr. Bickner considered Petitioner's application under the provisions of Chapter 403.918, Florida Statutes, which requires a two step evaluation. In the first step, the project must be determined to meet water quality standards. If it does, as a second stage, the project must be determined not to be contrary to the public interest. The major water quality standard in issue here was that of dissolved oxygen along with that concerning BOD and other deleterious substances. The water body involved was classified as a Class III Water under the provisions of Rule 17-3.121, Florida Administrative Code, since it was designed to be a recreational, fish and wildlife habitat. The standards contained in the statute and the rule relate to surface water as opposed to groundwater and, as to the public interest question, Chapter 403 provides a list of seven factors which must be evaluated. In this determination the agency has wide latitude and no one factor is controlling. In evaluation, agency personnel try to look at the project overall. Specifically, the project cannot cause or contribute to an existing water quality violation. In evaluation, agency personnel do not look at the project by itself. They must keep in mind that other projects exist or are proposed for the area. This is known as the cumulative impact of the project which is provided for in Section 403.919, Florida Statutes. As to the variance requested, this is also provided for by statute. The criteria require that the petition be based on some specific ground. In the instant case, the ground utilized by Petitioner was that there was no alternative to the dissolved oxygen level proposed. Granting of a variance is totally within the discretion of the Department even if Petitioner can show grounds therefor. Mr. Bickner was at the site only once. He approached from the south. At the low end of the approach was a mixture of wetlands and upland vegetation, but as he got toward the site the upland species dropped off and only the wetland species only remained. These were primarily sawgrass, cattails, and the like. He was satisfied that there was no obvious break in jurisdiction, and the testimony of Mr. Beever confirmed that jurisdiction over the site was gained through the wetlands character of the property from the site down to the Alligator Alley Canal, which is considered a water of the state. The site consists primarily of sawgrass and muhli grass with minor amounts of other grasses. The site seems to rise toward the 8 Mile Canal where there is an invasion of Brazilian peppers and other exotic species. Mr. Bickner was looking for upland species and found only one specimen of one species, a few of another, and no invasion of slash pine on the site at all. As a result, he concluded that the site was not an upland site. There was no standing water on the site at the time Mr. Bickner visited it, but the soil was wet to the surface. In addition, there was a large number of recently dead shells in low spots which had held water. There were some tracks of a large animal and a large number of smaller animal tracks and scats (scats are animal droppings). He also saw some birds which were too far away to identify and observed what he thought were crayfish tunnels near the cypress trees. Mr. Bickner found evidence of dried periphyton widely scattered over the site. Periphyton, an algae which attaches itself to other plants and which in times of inundation, forms sheets across the water connecting one plant to another, is a sign of previous inundation. The other plants on the site were not showing water deprivation stress, and there was no evidence of upland species invasion. All of this leads Mr. Bickner to conclude that the area has plenty of water and this opinion was enhanced by the lushness of the plants' growth. This, along with the high diversity of plant life, indicated to him a healthy ecosystem. To Mr. Bikner, the fact that the area was not currently inundated is not significant. In this particular area there are wet and dry seasons and, even in the dry season such as existed at the time of his visit, the soil was wet. The signs he saw indicated to him there has to be standing water on the site at some time. His visit was in January, which is well within the dry season. As to water quality, Mr. Bickner does not believe that the water quality standards will not be violated. In fact, by the nature of the project, Petitioner has, in Mr. Bickner's opinion, assured that it will be violated. A 20 foot deep pit must, in his opinion, result in low levels of dissolved oxygen below standards. Any water below seven foot in depth has little dissolved oxygen. Most dissolved oxygen is in the surface water, and there is little exchange between deep and surface waters. As a result, he concludes that the groundwater has low dissolved oxygen, a fact confirmed by Mr. Missimer. Dissolved oxygen is the only source of oxygen for fish and aquatic animals. Without dissolved oxygen, the fish die. There are currently no fish on the property. Mr. Bickner was also concerned with the biochemical oxygen demand which would further reduce the oxygen levels in the water. He was further concerned with the hydrogen sulfide levels coming from deterioration of plant material in the bottom of the pit, and iron which he found to be already in the groundwater. Mr. Bickner contends that during construction of the pit petro- chemicals will be introduced into the water, and that during the construction period the on-site water will have increased turbidity which will most likely be transmitted off-site as the pit is de-watered. There are management procedures which can reduce the risk, but none can avoid it entirely. Mr. Bickner is satisfied that the water quality standards will not be met. It is so found. Mr. Bickner also evaluated the property from the public interest standpoint, and in that regard he is satisfied there is a substantial potential for damage to adjacent properties by de-watering. Based on his experience and observation of other projects, he is satisfied there is no way to keep people employed on the site from using adjacent property for parking and vehicle maintenance. The witness believes that the 56 acres of habitat removed by the lake, and the remaining acres, which will be replanted, will be permanently impacted. While he admits that the property as it currently exists, may not be a prime habitat for the panther, there is some evidence which indicates panthers do cross it. He is concerned that the applicants submission here does not sufficiently answer all the questions as to impact on the public interest. The mechanics of the maintenance yard, soil storage and other potential areas of trauma are not explained satisfactorily, and Mr. Bickner does not see how all that is proposed can fit on the site. As a result, in his opinion, there must be some off-site impact. As to cumulative impact, since the valuable rock does not lie only under Petitioner's property, owners of the surrounding property may want to mine their properties as Petitioner proposes to do. If that happens, Mr. Bickner cannot explain how the Department can deny these subsequent applications. If the current application is permitted, taken together with the others, there would be a serious effect on the panther population. This opinion is not supported by evidence, however. If the public interest test is the only basis for disqualification of the project, (here the water quality test is also not met) a permit can still be granted if the applicant agrees to take appropriate mitigation steps at the site. Mr. Bickner is of the opinion that the applicant's mitigation plan to create the 100 foot wide shelf around the lake is not the same type of system which currently exists, will not fulfill the same function as the present property, and is not sufficiently large to replace what is being lost. One basis for granting the variance suggested by the Petitioner was the public interest, (the material was to be used for a public road), and the other was that there was no alternative way to get the material. While it is possible the rock would be used for public road, Mr. Bickner was concerned no assurances were given by the Petitioner that it would be. No contract has been signed yet, and Mr. Bickner is not satisfied that the letter from the Department of Transportation, indicating the rock there would suit its purpose, is sufficient indication that a contract would be signed. There is a possibility of making the pit shallower, which would permit the dissolved oxygen content of the lake water to meet state standards, but even if that problem were solved, Mr. Bickner is not satisfied that Petitioner has met the public interest test. Respondent has granted three permits and a variance to the Department of Transportation to build a portion of I-75 across Alligator Alley in Collier County. These permits are for the dredging of canals parallel to the roadway and to develop a borrow lake of 73.1 acres to be excavated to a depth of from 6 to 9.7 feet. The variance in question applies to all three projects and relates to the dissolved oxygen level. The DOT variance was applied for on the basis that no practical means for avoidance of the pollution existed. The Department of Transportation did not request a variance for BOD or for toxic and deleterious substances or iron. Mr. Bickner, admitted that these permitted projects would possibly have the same problem of oils and greases as he foresees with Petitioner's project. Nonetheless, he concludes that Petitioner's project should not be permitted, even though the Alligator Alley canals are already below standards, because to do so would contribute to a currently existing violation. Mr. James Beever, an Environmental Specialist with the Department of, Environmental Regulation, visited the site on several occasions, both on the ground and from the air. He observed much of the same flora and fauna observed by the other visitors who testified in this case and took color photographs of the area which portray the character of the property. All of the plants he discovered on the site are on the DER jurisdictional list and, on at least one occasion, from the air, he saw standing water on the site. In his opinion, the property is a fresh water wet prairie system which is admittedly drier than it should be. The plants he saw on the site indicate the jurisdiction of DER if there is a connection to other waters of the state, and in Mr. Beever's opinion, there is connection through the flow of sheet water south from the site to the I-75 (Alligator Alley) canal; then, east to the 8 Mile Canal; then south to the Fuqua Union Canal which empties southwest to the Gulf of Mexico. In his opinion, therefore, this is definitely jurisdictional land, and it is so found. The site supports an underground system of roots as well as the upper portion of the, plants existing thereon. He observed periphyton and many other animal tracks and scats. He also saw signs of regular inundation such as numerous snail shells, and he is satisfied there is no indication of a change in the area from the wetlands to an upland area. Admittedly, the area has been dry for a while. Even after Hurricane Floyd in 1987, there was no standing water. The site is, in his opinion, definitely productive, however. The vegetation existing thereon stabilizes the soil and provides food for snails, insects and crayfish which are on the bottom of the foodchain for other life forms on the property. The grasses provide a habitat for animals such as cotton rats, roosts for birds, pollen for insects, all which, themselves, become food for the larger animals. This wetland is a part of a large wetland prairie system and part of the Fuqua Union drainage basin, and acts as a filter for the water system for the area. According to Mr. Beever, most borrow pits like this are located on uplands which then provide rain water lakes. The instant pit, however, is in a wetlands area and if built, he believes, will engender violations during the mining operation. Groundwater coming in will contain iron and hydrogen sulfide which will combine with the dissolved oxygen in the water and further deplete the already low oxygen levels. All of this will constitute a violation of the rules regarding waters of the state since the waters within the pit would fall within that category. Mr. Beever is also concerned with the `bridge over the 8 Mile Canal and the turbidity connected with its construction and removal. In substance, Mr. Beever is convinced that construction of the project will create violations of the water quality standards for the area. As to the public interest, the wetlands character of the site will be completely lost. The vegetation will be removed, and the animals utilizing it will either leave or be destroyed. After, construction, some natural healing will occur, but a long-term maintenance program will be required to provide even different functions for the land than those which currently exist. In that regard, Mr. Beever is convinced that the applicant's proposed restoration plan is not acceptable. It will not replace the lost functions of the site; it will replace the species removed with a different ecosystem; it will provide a habitat for different species of animals and birds; it will adversely affect the shoaling and erosion in the lake itself (this is found to be without merit); it will have some adverse effect on the property of others; and will have an adverse cumulative impact on the area. The habitat will not be used any more by endangered species such as the wood stork and the panther. Even assuming, arguendo, the plans were suitable, in Mr. Beever's opinion, the project would not work here because of the lack of information on what the actual water level of the lake will be. The plant species proposed may not remain because of possible changes in water level in the lake. In addition, the marl berms will dry out over the three years of their life while the pit is being worked, and form a location for a lot of invasive upland plants. Much of Mr. Beever's concern is shared by Mr. Barnett, of the Game and Fresh Water Fish Commission, who indicated that birds now frequently use the area for nesting and feeding because of its wetlands character. Endangered species such as the Florida panther cross it from time to time as does the Florida black bear. Human encroachment reduces the panther's territory and reduces the area for forage of deer, which are the principal food of the panther. The bigger issue, however, is the cumulative impact. The 80 acres is not so important by itself, but to permit its removal would set a precedent for future encroachment by others. Mr. Barnett's experience is that restoration plans are quite often not successful. Even the successful ones, however, replace the removed system with a different system, and the species which now use the property would find it much less desirable as changed. Specifically, the bear, the deer, and the panther would find it unusable as proposed. At the present time, the deer spend their days in the pines forest to the north of the property, coming out onto the area, in question only at night to feed. It is during the night that the panther stalks. As presently constituted, this property is of no benefit to the wood stork or the red cockaded woodpecker. The Cape Sable sparrow could use it but does not. The development of Golden Gate Estates to the north and east and south of the property has a two pronged effect on the area in question. The southern portion of Golden Gate Estates has been abandoned, but the central and northern portions will be developed. On the one hand, it is likely that the increased population to the north and east will make the Petitioner's property less desirable and make access to it more difficult for the wildlife currently utilizing it. On the other hand, removal of the northern and central portions of Golden Gate from usable area for the panther and other species make it more important that Petitioner's area, which Barnett claims is not likely to be developed, remain as an animal habitat to offset the encroachment of the development area. There is no evidence to support this prediction of non- development, however. History tends to indicate otherwise.

Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that application number 07256-F be APPROVED subject to the special conditions set forth above. DONE AND ORDERED this 15th day of July 1987, in Tallahassee, Leon County, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399-1550 904/488-9675 Filed with the Clerk of the Division of Administrative Hearings this 15th day of July 1987.
The Issue Whether Petitioner's application for a dredge and fill permit under Chapter 403, F.S. and PL 92-500, to conduct rock mining activities in Dade County, Florida should be approved. At the commencement of the hearing, the parties orally stipulated that the only matters in issue were those relating to biological integrity, lead, oil and grease, and dissolved oxygen, as affecting water quality pursuant to Chapter 17- 3, Florida Administrative Code, and the cumulative impact of this and other like projects in the general area in question. Additionally, Petitioner had amended his petition prior to hearing to allege that Respondent lacked jurisdiction over the proposed excavation activities because the project site is not located in the waters of the State. The jurisdictional question will he determined hereinafter in Conclusions of Law. At the hearing, Petitioner presented the testimony of five witnesses and submitted ten exhibits. Respondent called four witnesses and submitted six Rodney Dehan were received in evidence at the request of Petitioner as reflected in the hearing transcript. considered, and those portions thereof not adopted herein are deemed to be either unnecessary, irrelevant, or unsupported in fact or law. Petitioner Florida Mining and Materials Corporation, Tampa, Florida, a wholly owned subsidiary of Moore-McCormick Corporation, conducts rock mining 566 acres of land in Section 14, Township 55 South, Range 38 East, Dade County, Florida, for rock mining purposes. The tract of land is located about one mile Highway 41). The property is bounded on the east by Levee L31-N and a drainage canal. There are no public or private roads at the present time providing By application, dated May 19, 1980, which was filed with Respondent Department of Environmental Regulation (DER) on June 16, 1980, Petitioner (Testimony of Coleman, Petitioner's Exhibit 1) Respondent asked for additional information concerning the proposed To Deny the application on July 21, 1981. The stated grounds for the intended denial were that the proposed project would destroy approximately 566 acres of quality by the assimilation and transformation of nutrients, and that the project would destroy productive biological habitat which depends on and notice further stated that pollutants could be expected to enter waters of the State through the pits which would provide direct openings to the Biscayne create water bodies unable to meet State water quality standards. Finally, the notice stated that the cumulative impact of existing and proposed similar Everglades and the ground waters of the Biscayne aquifer, and that therefore Petitioner had not provided reasonable assurance pursuant to Rule 17-4.07 and not result in violations of water quality standards for surface waters. At the hearing, by stipulation of the parties, Respondent abandoned its concerns as to Respondent's Exhibit 1) Petitioner plans to dredge approximately 70 percent of the land area by dragline will total approximately 25,427,000 cubic yards. Approximately 353,000 cubic yards of the dredged material will be used as fill for roads, be transported to an on-site processing plant where it will be crushed, sized, washed, and then conveyed to storage piles of various size aggregate. Water and containing "face powder" size limestone residue will then be piped back into the lake. Material from the storage piles will be conveyed to a final wash station and sent to storage bins for loading on trucks, or by conveyer belt to an adjacent railroad spur for loading. No chemicals or additives are used in processing the material. Motor vehicles and heavy equipment used in the operation will use diesel fuel or unleaded gas. No oil or grease is introduced in the manufacturing cycle, although such materials will necessarily be used in connection with the operation of vehicles and equipment. A perimeter buffer zone of 85 feet will separate the pit excavations from adjacent property lines on the north, south and west sides of the site. On the east side, a rail siding will be set back 200 feet and the lakes 400 feet from the Levee L31-N right-of-way. A perimeter berm of undetermined size will encircle the entire site. A 25 foot wide road from the north of the site to the Tamiami Trail will be constructed on an 80-acre "alley" to permit access to and from the mining area. Maintenance roads will be constructed around the perimeters of the four lakes. An 18 foot wide drainage ditch will be constructed immediately behind the perimeter berm to receive runoff from the adjacent maintenance roads. Earth berms will encircle all excavated areas to eliminate surface water inflow. Lake excavation areas will comprise approximately 70 percent, or 394 acres, of the 566 acre site. The remaining land area will be 172 acres. Petitioner will be able to mine approximately 70 percent of the estimated twenty-four million tons of existing rock which underlies the land area. It is estimated that mining operations will take place for approximately fifteen to twenty years to remove the available rock material. There is a 2 foot layer of topsoil overlying the lime rock which will be stored to return non-excavated areas to their original level when the project is completed. The areas will be revegetated at that time. (Testimony of Coleman, Petitioner's Exhibits 1, 5,6,8) Although the project area has groundwater levels within one foot of tide land surface for most of an average year, surface water is on the site during a maximum of 36 days a year. Vegetation is present on approximately 55 percent of the property. The dominant species is sawgrass, although several other wetland species such as beakrush, marsh fleabane, spike rush, and maiden cane, are present to a lesser extent. Periphyton algal mats are found throughout the project area. Such mats provide habitat and protection for a variety of organisms and their egg masses. Sawgrass is one of the species listed in Rule 17-4.02(17), Florida Administrative Code which, under Rule 17- 4.28, Florida Administrative Code, is used as a guide in the establishment of the border of certain water bodies listed therein. (Testimony of Lotspeich, Molnar, Gatewood, Kraft, Respondent's Exhibits 4-6) The following findings address the stipulated issues as to whether Petitioner has given Respondent reasonable assurance that the proposed project will not result in water quality violations with respect to concentrations of lead, oil and grease, dissolved oxygen, and impacts on biological integrity in Class III waters: Lead--Petitioner will not use materials containing lead in the conduct of its rock mining operations, and therefore no water quality violation active rock mining pits in the general area revealed only negligible amounts of lead. (Testimony of Sullivan, Baljet, Petitioner's Exhibit 10) heavy equipment which require oil and grease incident to its excavation and mining operations. DER Rule 17-3.061(1)(j), Florida Administrative Code (as dissolved or emulsified oils and greases shall not exceed 5.0mg. per liter, nor shall visible oil be present to cause taste, odor, or interfere with the general area show that State standards are being met. It would take over 24,000 pounds of oil and grease to result in a violation of the quality standard on equipment and inspection should prevent other than insignificant discharges of oil and grease. Although oil sheens have been observed on water surfaces of situation would exist as a result of Petitioner's proposed operations. (Testimony of Sullivan, Baljet, Lotspeich, Kraft) waters provides that the concentration of dissolved oxygen shall not be less than 5 mg. per liter. Petitioner's proposed operation will not discharge oxygen dissolved oxygen. Excavation of the proposed lakes will permit interchange from the pits and surrounding groundwater. As groundwater rises to the surface, aeration. Tests of several water filled rock pits in the surrounding area meet state standards as to dissolved oxygen. The storage of excavated muck soil in which could lower the dissolved oxygen concentration, but the perimeter berms surrounding the lakes should prevent other than a minimal amount of such organic powder" size lime rock residue could present a suspended solids and BOD problem over a long term as it eventually forms a layer on the bottom of the lake. Such penetration and re-suspend easily. Although the waters of the rock pits probably will not meet the State standards of 5.0 mg. per liter at various of the groundwater in the area. Deep water bodies provide less water circulation and consequent lowered dissolved oxygen levels than do shallow (Deposition), Petitioner's Exhibit 10) d. Biological Integrity--Rule 17-3.121(7), F.A.C. provides that the reduced to less than 75 percent of established background levels. Sampling equipment to perform this test requires a minimum of seven inches of water for a October, 1981 after a hurricane at which time there was approximately 14 to 16 inches of surface water on the site. The test showed a moderate to slightly low levels and survive during the normally dry periods in pockets of water. They have a high degree of adaptability. Disruption to the regimes will be caused to the pit excavations which will divert sheet flow around the site. However, actual effects of the project cannot be determined until tests can be made after construction. However, the ability to perform valid testing on a sawgrass prairie where surface water is present only after rainfall over a total of 36 days a year is remote. Such tests are designed for lakes and streams. In the opinion of DER's chief biologist as to the use of a sampler, ". . .it is rather ridiculous to put it on a sawgrass prairie". (Testimony of Sullivan, Pruitt, Ross (Deposition)) DER asserted jurisdiction over Petitioner's proposed activities based on the fact that there is continuous sawgrass vegetation from the site southwest to the Shark River which begins at Florida Bay some 60 miles away. The Shark River is located in the southwestern portion of the State and sloughs from thee river proceed in undefined patterns to the northwest. Sheet flow from the sawgrass prairie area travels slowly in a southwesterly direction where it is drained by the Shark River system. However, only approximately 10 percent of surface water flow over Petitioner's site would reach the defined river which ends approximately 15 to 20 miles from the coast. No exchange of water from the Shark River takes place at Petitioner's site, nor does any tidal flow from Florida Bay reach that area. The sawgrass and other wetland species survive due to the high groundwater level in the area which generally results in damp soils. DER does not seek to assert jurisdiction arising from the project's proximity to the L31-N canal due to the existence of the adjacent dike which would prevent any discharge from Petitioner's site. However, it does consider that the Petitioner's land is within the landward extent of waters of the State in that it is a part of the water body either of the Shark River or of Florida Bay. (Testimony of Lotspeich, Molner, Gatewood, Kraft, Respondent's Exhibit 1) Although some 33 applications to conduct rock mining activities in Dade County have been received by DER over the years, the agency did not assert jurisdiction over those located east of the L31-N canal due to the fact that the canal altered the natural hydrological pattern of the area, and wetland species of vegetation no longer were dominant in the area. There is no other pending application for rock mining activities other than that of Petitioner to the west of the canal at the present time. (Testimony of Lotspeich, Kraft, Respondent's Exhibits 2-3) An additional ground stated by DER for proposed denial of the project is that approval of Petitioner's permit would set a precedent for future similar operations and that the cumulative impact of such projects would result in a decline of water quality of the surface waters of the Everglades. However, no applications for similar permits in the area near Petitioner's site are pending, nor have any been granted west of the L31-N canal to date. (Testimony of Lotspeich, Kraft, Respondent's Exhibit 2) It would therefore be speculative to base such a finding upon concerns about future possible applications which might be filed due to the presence of limestone rock in sufficient quantities for profitable operations. In 1976, Petitioner's request for a variance from Dade County zoning ordinances to permit mining on its site was denied by the county commission. Petitioner appealed the denial to the Dade County Circuit Court, which found that the county had acted in an arbitrary manner by permitting essentially identical mining activities on nearby tracts of land, and ordered the county to grant necessary permits for mining activities upon proper application by Petitioner. This decision was appealed to the Third District Court of Appeal which affirmed the lower court in Case No. 77-1223 on October 17, 1978. Thereafter, by resolution, dated July 19, 1979, the Dade County Board of County These conditions require adequate turbidity controls during construction, a temporary perimeter berm to permit silt runoff, stockpiling of excavated topsoil of the property to pre-excavation condition after completion of operations, construction of adequate culverts to maintain overland sheet flow, and other the conditions require the posting of a surety bond to ensure compliance with county requirements, and further purport to limit transfer of title to the the conclusion of mining operations, utilize the property for passive recreational purposes, or as a wildlife refuge.

The Issue The issue for determination in this proceeding is whether Respondent, E. Speer and Associates, Inc. (the "Applicant"), should be granted a permit for the construction of a permanent docking facility pursuant to Sections 403.91-403.929, Florida Statutes, and Florida Administrative Code Chapter 17.
Findings Of Fact Whether Quantified Hydrographic Studies Are Necessary For All Marina Applications To Provide Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards Speer's Exceptions Nos. 1, 4, 5, 6, 7 and 8 in whole or in part take exception to the Hearing Officer's conclusion (stated as a finding of fact) that it is not possible to demonstrate adequate flushing without "quantifying flushing rates and pollutant dispersal rates using objective methods and appropriate hydrodynamic data." (R.O. at 20, 22-24, 47, 49-50, 54, 57-58; F.O.F. Nos. 33, 35, 38-39, 40, 43-45, 64, 66, and 69) It is clear from the tenor of the entire recommended order that the Hearing Officer believes that as a matter of law an expert's opinion is not sufficient to provide reasonable assurances that flushing will be adequate to prevent violations of water quality standards unless that opinion is based on quantified conclusions generated by objective methods and appropriate hydrodynamic data. (R.O. at 47, 49-50, 57-58) Thus, for example, the Hearing Officer opines that quantification of flushing rates and pollutant dispersal rates using objective measurements of appropriate hydrodynamic data is an essential element of the prima facie showing required to be made by the applicant. (R.O. at 47; C.O.L. No. 11) The Hearing Officer places great significance an the following excerpt from the opinion in 1800 Atlantic Developers v. Department of Environmental Reculation, 552 So.2d 946 (Fla. 1st DCA 1989), rev. den., 562 So.2d 345 (Fla. 1990): 1800 Atlantic filed 34 exceptions to the recommended order, most of which were denied in the Department's final order . . . . The final order approved and adopted most of the findings of fact and conclusions of law in the recommended order and denied the permit. The following stated rulings and reasons there for are significant to the issues on this appeal. (emphasis added) We must note at this point that there is no finding of fact in the hearing officer's recommended order that quantifies how productive the marine habitat may be in this case, and no record support for the suggestion that there would be some quantifiable diminution in the quality of the marine habitat attributable to this project [footnote omitted]. (emphasis added) Exception 23 filed by 1800 Atlantic challenged the hearing officer's finding that the project will adversely affect the conservation of fish and wildlife, fishing or recreational values, and marine productivity in the vicinity . . . The Department rejected this exception based upon the hearing officer's general statements, without any quantification whatsoever, of adverse effects upon these matters . . . (emphasis added) 1800 Atlantic, 552 So.2d at 951-952. I do not concur that 1800 Atlantic stands for the proposition that quantified hydrographic measurement of flushing is in all cases an essential element of a prima facie showing that a marina project will not cause violations of water quality standards. Notwithstanding the above noted statement of the court in 1800 Atlantic that "there is no finding of fact . . . that quantifies 'how productive the marine habitat may be' . and no record support . . . that there would be some quantifiable diminution in the quality of marine habitat attributable to [the] project," 552 So.2d 951, the court did not reject the finding that the project adversely affected the conservation of fish and wildlife, fishing or recreation values, and marine productivity. Indeed, had the court rejected the above finding due to lack of quantified findings the court would never have gone on to reach the issue of mitigation because in 1800 Atlantic mitigation could only become relevant if the applicant was unable to provide reasonable assurance that the project satisfies the public interest criteria of Section 403.918(2) (a), Florida Statutes. See Section 403.918(2)(b), Florida Statutes. I do agree that in some cases quantified hydrographic studies of flushing may be required in order to provide reasonable assurances. Thus, in Rudloe v. Dickerson Bavshore, Inc., 10 FALR 3426 (DER Case No. 87-0816, June 9, 1988), my predecessor held that a dye tracer study was necessary to provide quantitative information about dilution rates and directions on dispersion of pollutants emanating from a proposed marina site which was in "close proximity" to Class II waters approved for shellfish harvesting. 10 FALR at 3447-48. However, the need for such quantified studies must be determined on a case by case basis and is not required as a matter of law for all marinas. 5/ Far me to determine as a matter of law that experts may establish a fact only by certain types of evidence would be an unwarranted and unwise intrusion into the scientific domain of the expert. Thus, in Kralik v. Ponce Marine, Inc., 11 FALR 669, 671 (DER Final Order, Jan. 11, 1989), my predecessor held that expert testimony with regard to flushing does not lack credibility just because a hydrographic study had not been conducted. Of course, the finder of fact has the ultimate say on how much weight an expert opinion should be given if it is not based on a quantified study. Thus, whether an expert testifying on adequacy of flushing has conducted a quantifiable hydrographic study merely goes to the weight of the evidence. Kralik, 11 FALR at 671. I only conclude that a quantified hydrographic study for a proposed marina is not in all cases essential for a showing of reasonable assurances that water quality standards will not be violated. Accordingly, to the extent that the Hearing Officer's findings of fact state that a quantified hydrographic study is required in all cases as a prima facie element of a showing of reasonable assurance that a project will not violate water quality standards, I reject such statement as a mislabled and incorrect conclusion of law. Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards I read Speer's Exceptions Nos. 1, 3, 4, 5, 6, 7 and 8 in whole or in part as taking exception to the Hearing Officer's finding that under the facts of this case a quantified hydrographic study was needed in order to provide reasonable assurance that the project would not cause violations of water quality standards, and that because such a quantified hydrographic study had not been conducted, reasonable assurances had not been provided. (F.O.F. Nos. 33, 35, 38- 39, 40, 43-45, 64, 66 and 69) As noted by the Hearing Officer, the applicant's expert testimony concerning the adequacy of the flushing consisted of general statements describing visual observations of river and tidal flows which, together with past experience and knowledge of the general area of the project, formed the basis for the experts' opinions that a quantified hydrographic study was not necessary for this project. (R.O. at 22-23) Thus, far example, Mr. Charles C. Isiminger, accepted as an expert in marina design and hydrographic engineering testified that based on his knowledge of the area, its riverine and tidal flows, a hydrographic documentation was not needed to provide reasonable assurance that the project would not cause water quality violations. Mr. Isiminger also testified that any pollutants entering the water from the marina would be flushed out of the area within one tidal cycle. (Tr. at 65-66, 70, 77- 79, 93, 110, 125, 128, 134) Mr. Thomas Franklin, an environmental supervisor from the Department testified that: the hydrographic survey was not really necessary due to the location of the project being in open waters and in close vicinity to the Inlet with a large volume of tidal waters moving in this area, plus the fact that it was further enhanced by flushing due to the St. Lucie River being -- basically coming around Hell Gate point [sic] and funneling out into this estuary. (emphasis added) TR at 437. Other experts also testified that the area was well flushed and that a quantified hydrographic study was not needed in this case. (Jacqueline Kelly, Tr. at 187; John Meyer, Tr. at 319, 322, 341; Gerald Ward, Tr. at 44749) 6/ Speer asserts that the Hearing Officer's finding that a quantified hydrographic study is required in this case cannot stand in light of the unrebutted expert testimony that the marina site will be well flushed and that the rate of flushing provides reasonable assurances the water quality standards will not be violated. I have found no competent substantial evidence in the record which would support a finding that under the facts of this case a quantified hydrographic study is required. I did note that in Footnote 21 of the Recommended Order (R.O. at 20) the Hearing Officer states: Tidal range is only one of the types of data used to quantify flushing rates and pollutant dispersal rates. See TR at 78. Other appropriate data include: overall flow rates, mid tide flow, flow amplitude (the magnitude of the flow without regard to direction, i.e., speed as opposed to velocity), horizontal current distribution, downstream plume characteristics, and field verification using a dye tracer. All of this data is needed to fully describe and quantify flushing rates and pollutant dispersal rates. (citing testimony of Mr. Isiminger at Tr. 88-94) At first blush this may appear to be competent substantial evidence supporting a finding that a quantified hydrographic study is necessary in this case. However, when the testimony is read in its complete context, it is clear that Mr. Isiminger is testifying as to what is necessary to do a hydrographic study when one is needed, and is not testifying that such a study is needed in this case. (Tr. 88-94). I also note that the record contains a memo written by Dr. Kenneth Echternacht, a hydrographic engineer employed by the Department. (Tr. at 67-70) This memo was admitted without objection. (Tr. at 23) The memo states in part that "without . . . hydrographic documentation, reasonable assurance cannot be given that the project will not cause problems." (Tr. at 70; Pet. Exh. No. 10) 7/ Dr. Echternacht was not called as a witness at the hearing and the letter was not offered as evidence of the opinion of Dr. Echternacht or the Department at the time of the de novo hearing. To the contrary, the above noted testimony of Mr. Franklin and the testimony of Jacqueline D. Kelly, an environmental specialist of the Department accepted as an expert in evaluating impacts of environmental dredge and fill projects (Tr. at 187, 195; R.O. at 3), clearly establish that at the time of the de novo hearing the Department was of the opinion that further hydrographic documentation was not needed. The Hearing Officer noted that Mr. Meyer testified that the flushing is a "very, very complicated dynamic situation." (Tr. at 320). The testimony was as follows: Q. So you don't know for sure whether the currents here impact this at all or stay offshore from it? A. Oh, the currents definitelv affect it, and you do have interchange -- as I mentioned before, a very high rate of interchange on a daily basis on every tide. Q. Are you saying that the current that flows through here every day flows right through the site? A. We're dealing with two different things here. We're dealing with your currents, your general migration of waters from the estuary from the inland areas down. You're also dealing with tidal effects coming in and out, and it's a very, very complicated dynamic situation. For me to try to tell you exactly how these things work would be impossible without having a very, very long drawn-out expensive study done on the entire area, and I have not reviewed any studies like that. Tr. at 319-20 (emphasis added) When taken in its context it is clear that Mr. Meyer is testifying that there is a very high rate of exchange on a daily basis on every tide. The fact that he viewed the exact details of the flushing as very complicated in no way retracted his statement that there was a very high rate of exchange on every tide. My review of the record leads me to concur with Speer that no testimony, either on direct, cross-examination, or examination by the Hearing Officer, nor any other evidence was introduced to rebut the expert testimony presented by Speer and the Department that flushing on the site was adequate to provide reasonable assurance that water quality standards will not be violated. 8/ As a general rule, the trier of fact may not arbitrarily reject uncontroverted evidence as proof of a contested fact. Merrill Stevens Dry Dock Co. v. G. & J. Investments, 506 So.2d 30 (Fla. 3d DCA 1987), rev. den., 515 So.2d 229 (Fla. 1987); City of St. Petersburg v. Vinoy Park Hotel, 352 So.2d 149 (Fla. 2d DCA 1977); In Re: Estate of Hannon, 447 So.2d 1027 (Fla. 4th DCA 1984). This does not mean that a mere scintilla of unrebutted evidence is sufficient to establish a contested fact in an administrative hearing. At least in the context of administrative proceedings, the unrebutted evidence still must be competent substantial evidence to support a finding of fact. 9/ There is no suggestion that the Hearing Officer rejected the unrebutted testimony of the experts of Speer and the Department as not being competent substantial evidence. In fact, in the light of the testimony of Mr. Isiminger (Tr. at 65- 66), Mr. Ward ( Tr. at 447-449), Mr. Meyer (Tr. at 238- 239), and Mr. Franklin (Tr. at 345-350), it is beyond peradventure that there is competent substantial evidence to support a finding that flushing is adequate to provide reasonable assurance that the marina will not cause violations of water quality standards. It is clear from the context of the Recommended Order that the Hearing Officer believed that reasonable assurance had not been provided only because he believed that a quantified hydrographic study was required as a matter of law. Although I reject the Hearing Officer's conclusion that a quantified hydrographic study must be conducted as a matter of law for all marina applications, I must still determine whether a quantified hydrographic analysis is required under the facts of this case. In Rudloe v. Dickerson Bayshore, 10 FALR 3426 (DER Final Order, June 9, 1988) it was held that a hydrographic study was not adequate because it did not include a quantified dye tracer study. Id., 10 FALR at 3448. In Rudloe, as in this case, the marina was located in Class III waters, but near Class II waters. However, in Rudloe, the marina site was much closer to the Class II waters (approximately 1,700 feet in Rudloe (10 FAIR at 3430) as compared to approximately 8,000 feet in this case). (R.O. at 16, F.O.F. No. 26) Also, the Rudloe case is significantly different from this case in that competent substantial expert opinion was presented in Rudloe that the marina would adversely impact the Class II shellfish harvesting area. See Rudloe, 10 FALR at 3433-35, 3437-38 (testimony of DNR expert that operation of marina would result in closure of waters to the harvest of shellfish; testimony of Dr. Robert Livingston that the hydrographic drogue studies conducted were inadequate.) In this case, neither expert nor lay testimony was offered by Barringer to show that operation of the marina would result in violation of water quality standards or have any adverse impact on the Class II shellfish waters. 10/ I conclude that the facts of this case as found by the Hearing Officer are not sufficiently similar to the facts of Rudloe so as to justify holding as a matter of law a quantified hydrographic study is necessary to establish the required reasonable assurances. Since the record contains competent substantial evidence that flushing is adequate to provide reasonable assurance that the marina will not cause water quality violations, and since there is no competent substantial evidence in the record to support the Hearing Officer's contrary finding, I must accept the exception of Speer and reject the Hearing Officer's findings of fact to the contrary. In this case I note that I am not so much rejecting findings of fact as rejecting a conclusion of law. As I noted, the Hearing Officer's finding is really based on a conclusion of law which I reject. This leaves only unrebutted competent substantial evidence that there will be adequate flushing to provide reasonable assurance that the operation of the marina will not result in water quality violations. There is no rational basis to reject this unrebutted competent substantial evidence. Therefore, I must accept as proven that the applicant has provided the reasonable assurances that operation of the marina will not result in water quality violations. Merrill Stevens Dry Dock; City of St. Petersburg; Estate of Hannon; supra, Effect On Class II Waters Speer's Exceptions Nos. 7 and 8 take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the marina would not have a "negative effect" an the Class II waters of the St. Lucie Inlet and the Great Pocket. (F.O.F. No. 43) Rule 17-312.080(6)(b), Fla. Admin. Code provides: The Department also shall deny a permit for dredging and filling in any class of waters where the location of the project is adjacent or in close proximity to Class II waters, unless the applicant submits a plan or proposes a procedure which demonstrates that the dredging or filling will not have a negative effect on the Class II waters and will not result in violations of water quality standards in the Class II waters. In this case expert testimony was presented by Speer and the Department that due to the distance of the marina site from the Class II waters (8,000 feet) the marina site was not in close proximity to the Class II waters, and due to the rapid flushing of the area, the construction and operation of the marina would neither have a negative effect nor would result in violations of water quality standards in the Class II waters of St. Lucie Inlet and the Great Pocket. (Isiminger, Tr. at 96, 126-27; Meyer, Tr. at 254-55) I find that the record contains no competent substantial evidence to rebut the evidence introduced by Speer and the Department that the marina will have no negative effect on Class II waters and will not result in violation of water quality standards in Class II waters. Accordingly, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In Re: Estate of Hannon; supra. Reasonable Assurance That Operation Of The Marina Will Not Result In Prop Dredging Or Violations Of The State Water Quality Criterion For Turbidity Speer's Exceptions Nos. 1, 2, 9-12, and 16 in whole or in part take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the boat traffic from operation of the marina would not cause prop dredging or violations of the water quality criterion for turbidity. (F.O.F. Nos. 33-34, 45, 48, 52-53, 64, and 67) 11/ On one hand, there was testimony that the depths of the marina, in combination with the size of boats allowed in the various slips, would allow for a one foot clearance from the bottom of the boats to the bottom of the marina, and that this clearance, in combination with speed limits in the marina, would provide reasonable assurance that operation of the marina would not result in prop dredging or turbidity violations. (Isiminger, Tr. at 104-107, 118; Meyer Tr. at 263-65, 299, 304- 305; Kelly, Tr. at 189-190; Ward, Tr. at 460) On the other hand, Bruce Graham, admitted as an expert in marine biology testified that: "A large boat, three feet from the bottom, I think would resuspend sediment." (Graham, Tr. at 378). The Hearing Officer, noting that when asked if one foot clearance is sufficient to prevent prop dredging and resultant turbidity violations, a Department witness, testified: I would have to say that we simply don't have enough documentation to know this for a fact. We know that a foot gives us a degree of comfort that there will not be prop wash. In certain instances -- a tug boat, for instance, you know, with huge engines, you're going to have prop wash over a much -- over a large area and with probably much more than a foot of clearance. But for the normal, typical marina a foot, as I say, gives us a degree of comfort that we have settled on. Neyer, Tr. at 264. The Hearing Officer concluded that the witnesses of Speer and the Department could not explain the reasons or efficacy of the "one foot policy" except to say that in their experience the one foot policy was adequate to prevent prop dredging and turbidity violations. (R.O. at 28 n.35)0 The Hearing Officer thus found that Speer and the Department failed to "prove up" the one foot policy -- i.e., failed to elucidate and explicate the reason for the policy. 12/ Clearly the Hearing Officer placed more weight on the testimony of Mr. Bruce Graham than that of Isiminger, Meyer, Kelly and Ward. Since I cannot say that the testimony of Graham was not competent substantial evidence, I am not at liberty to reweigh the evidence or reject the Hearing Officer's finding of fact. See, Florida Dept. of Corrections v. Bradley, 510 So.2d 1122 (Fla. 1st DCA 1987); Heifetz v. Department of Business Regulation, 475 So.2d 1277, 1281 (Fla. 1st DCA 1985); Sections 120.57(1)(b)10., and 120.68(10), Florida Statutes. Speer contends that Barringer presented no evidence that prop dredging will cause sufficient turbidity to violate the state water quality turbidity criterion of 29 NTUs. 13/ That contention misses the point. The burden is on Speer to establish by the preponderance of evidence that reasonable assurance has been provided that operation of the marina will not result in violations of the water quality criterion for turbidity. Florida Department of Transportation v. J.W.C., Co., 396 So.2d 778 (Fla. 1st DCA 1981). The Hearing Officer, as the finder of fact, concluded that Speer failed to do so. Accordingly, I reject the exception of Speer and accept the Hearing Officer's finding of fact that Speer failed to provide reasonable assurance that operation of the marina would not cause prop dredging or violations of the state water quality criterion for turbidity. Manatee Impacts and the Public Interest Test Speer's Exceptions Nos. 13 and 17 take exception to the Hearing Officer's finding that Speer failed to do a quantified study of impacts to manatees and therefore failed to provide reasonable assurance that the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat. (F.O.F. Nos. 61, 64 and 68) The Hearing Officer reasoned as follows: Instead of a traffic study, the Applicant and DER presented evidence in the form of general statements that manatees need not migrate north and south through the approach channel. According to the Applicant and DER, manatees can migrate across the project site by one of two alternative routes. They can migrate in one or two feet of water under moored boats and then under wave breaks on the north and east piers, or they can migrate in the shallow water landward of the west boundary of the project. That evidence was not persuasive and was controverted by competent, substantial, and persuasive evidence that manatees would be deterred from migrating under the project footprint by substantial obstacles in their path. Manatees migrating under the project footprint would be exposed to 86 or more moving boats with powerful engines and drafts of four to five feet in waters covering approximately 20,800 square feet. It could be argued, or course, that 86 or more boats would not be moving in and out of the marina at one time. However, it is impossible to estimate occupancy rates, length of stay, and frequency of boat trips without a traffic study. (R.O. at 35, n. 51) As Speer's exception notes, there was testimony that because of the width of the river and boat speed restrictions in the project area, there would be no adverse impacts an the manatee from the marina. (Kelly, Tr. at 162; Meyer, Tr. at 255-56, 331- 32; Isiminger, Tr. at 130) The St. Lucie/Jupiter/Hobe Sound waterways are a major travel corridor for manatees. (DER Exh. No. 4) Between 1974 and December 1990, there were ten water craft related manatee fatalities within the boating sphere of influence of the project. (DER Exh. No. 4) In order to reduce impacts on the manatees, the proposed permit contains the following specific conditions: S.C. No. 13: The permittee agrees to install and maintain a minimum of one manatee education/display on the main access pier during and after construction. S.C. No. 15: The permittee agrees that any collision with a manatee shall be reported immediately [to DNR and U.S. Fish and wildlife Service]. S.C. No. 18: The permittee shall post four (4) manatee area/slow speed signs, two of which would be spaced along the perimeter pier and two of which would be located on the outside of the marina for all boating traffic to observe within the marina facility. (DER Exh. No. 3) 14/ There was testimony that the piers, once constructed, would not impair the passage of manatees. (Isiminger, Tr. at 114- 115) On the other hand, there was some testimony that manatees may have to go around the project rather than through it. (Meyer, Tr. at 311) The existing boat traffic past the site of the project to the Inlet was "rough1y estimated" at 50 to 100 boats a day. (Meyer, Tr. at 337) The U.S. Fish and Wildlife Service determined that "while [the project] may negatively affect, it is not likely to jeopardize the continued existence of the West Indian Manatee." (Tr. at 120-21) The Hearing Officer concluded that reasonable assurance as to adverse impacts on manatees could not be provided absent a quantified traffic study. (R.O. at 35, n. 51) In Coscan Florida, Inc. v. Department of Environmental Regulation, 12 FAIR 1359 (DER Final Order March 9, 1990), the Department held that the information needed to determine a marina's impact on manatees and the necessary actions to mitigate such impacts must be decided an a case by case basis. For example, in Sheridan v. Deep Lagoon Marina, 11 FALR 4710 (DER Final Order, Aug. 24, 1989), 15/ a marina sought to expand by adding 113 new wet slips. The marina was required to develop a manatee protection plan far the surrounding portions of the Caloosahatchee River, all new slips were limited to sail boats until the manatee protection plan was implemented and enforced, and power boat occupancy was limited to 75% of the total 174 wetslips in any event. The marina also made available a wet slip for use by the Florida Marine Patrol. In this case there is evidence of significant boat related manatee fatalities in the boating sphere of influence of the proposed marina. There is also evidence of existing traffic of 50-100 boats per day past the project site. In view of the fact that this project would add 86 slips and a public fueling facility, it seems likely that that the project will significantly increase both boat traffic and the threat of manatee collisions. Accordingly, I concur with the Hearing Officer that there is competent substantial evidence to support a finding that further studies are needed to determine what, if any, additional manatee protection conditions are needed to provide reasonable assurance that manatees will not be adversely affected. I conclude that the applicant did not provide reasonable assurance that the operation of the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat, and therefore failed to provide reasonable assurance that the project is not contrary to the public interest. Therefore, I reject the exception of Speer. Cumulative and Secondary Impacts Speer's Exception No. 15 takes exception to the Hearing Officer's finding that the applicant failed to provide reasonable assurance that there will be no adverse cumulative pacts created either by the cumulative effects of the object and existing similar projects, or by secondary pacts of the project itself. (F.O.F. No. 66) 16/ Cumulative impact analysis takes into consideration the cumulative impacts of similar projects which are existing, under construction, or reasonably expected in the future. Conservancy v. A. Vernon Allen Builder, supra; Section 403.919, Florida Statutes. Secondary impact analysis considers the impact of the project itself and of any other relevant activities that are very closely linked or causally related to the permitted project. Conservancy, 580 So.2d at 778; J.T. McCormick v. City of Jacksonville, 12 FALR 960, 980. 17/ Thus, in Conservancy the secondary impact analysis was required to consider the environmental impacts of development of 75 estate homes on an island where the development would be reasonably expected as a result of the permitted laying of a subaqueous sewer line. Similarly, in del Campo v. Department of Environmental Regulation, 452 So.2d 1004 (Fla. 1st DCA 1984), the Department was required to consider the environmental impacts of the foreseeable development of an island facilitated by the permitted building of a bridge to the island. In this case there is competent substantial evidence that there are other marinas located 1,750 feet downstream in Willoughby Creek, and 5,000 feet downstream in Manatee Pocket. (R.O. F.O.F. 31; Isiminger, Tr. at 112; Meyer, Tr. at 261) The record contains competent substantial evidence that the cumulative impact of the project and the existing marinas in Willoughby Creek and Manatee Pocket will not result in violations of state water policy. (Isiminger, Tr. at 125; Kelly, Tr. at 167) I cannot say that the testimony of Isiminger and Kelly on cumulative impacts is not competent, substantial evidence. In light of the fact that there is no competent substantial evidence to indicate that cumulative impacts would result in water quality violations, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersbur; In re: Estate of Hannon; supra. As to secondary impacts, the Hearing Officer pointed out that Speer did not introduce any evidence as to whether there would be secondary impacts to water quality as the result of further development or increased utilization of the uplands facilities. (See F.O.F. 66, n.59, R.O. at 39) Such further development or increased utilization of upland facilities is reasonably foreseeable and would be very closely linked or causally related to the building of an 86 slip marina with public fuel services. As noted above, the applicant has the burden of providing reasonable assurances as to cumulative and secondary impacts. Brown v. DER, supra; Conservancy, supra. However, neither the pleadings nor the pre-hearing stipulation raised the issue of the adequacy of the secondary impact analysis. In a case such as this where the Department's notice of intent to issue a permit has been challenged by a third party, the applicant's prima facie case need only include the application and the accompanying documentation and information relied on by the Department as the basis of its intent to issue. Florida Department of Transportation v. J.W.C., 396 So.2d 778, 788 (Fla. 1st DCA 1981). The petitioner challenging the permit must identify the areas of controversy and allege a factual basis for its contentions that the applicant did not provide the necessary reasonable assurances. J.W.C., 396 So.2d at 789. See also Woodholly Assoc. v. Department of Natural Resources, 451 So.2d 1002, 1004 (Fla. 1st DCA 1984). Since Barringer did not identify this issue and did not allege any factual basis for a contention that the secondary impact analysis was inadequate or incorrect, I may not rule on the issue in this order. Miscellaneous Exceptions To Findings of Fact Speer's Exception No. 14 takes exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the project will have no adverse impact on (1) the relative value of functions being performed by areas affected by the project, including seagrasses, shell fish, and fin-fish, and (2) recreational and commercial values in the vicinity. (F.O.F. No. 64) Speer contends that this finding is not supported in the record by competent substantial evidence and is contrary to unrebutted testimony of Ms. Kelly and Mr. Isiminger. (Kelly, Tr. at 159, 161-62, 165-67; Isiminger, Tr. at 73) I cannot say that the testimony of Isiminger and Kelly is not competent, substantial evidence, and I find no evidence in the record to rebut the testimony of Kelly and Isiminger. Therefore, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In re: Estate of Hannon; supra. Speer's Exception No. 3 takes exception to the Hearing Officer's finding that Speer failed to provide a current water quality analysis. (F.O.F. No. 35) A water quality analysis was submitted in April of 1990, shortly after the permit application was filed. (R.O. at 2, 19; F.O.F. No. 34) I find no competent substantial evidence in the record to suggest any reason for believing that the water quality has changed since April of 1990. I agree with Speer that, absent some specific reason for believing that the water quality has changed since the date of a study conducted contemporaneously with the permit application, there is no requirement to provide an updated water quality analysis. RULINGS ON EXCEPTIONS TO CONCLUSIONS OF LAW Need For Quantified Hydrographic Study Speer's Exceptions Nos. 1, 7 and 9, in whole or in part, take exception to the Hearing Officer's conclusions of law that a quantified hydrographic study was needed to provide reasonable assurances that the operation of the marina would not result in violations of water quality standards and would would not have a negative effect on Class II waters. For the reasons stated in Parts III(1), (2) and (3) above, I accept this exception and reject the above noted conclusions of law. Introduction Of Issues Not Set Forth In Pleadings Or Pre-Hearing Stipulations Speer's Exceptions Nos. 1, 2, 3, and 5, in whole or in part, take exception to the Hearing Officer's consideration of issues of (1) the need for a quantified hydrographic study, (2) the proximity of the site to Class II waters, (3) turbidity and prop dredging, (4) cumulative impacts, and (5) the need for a quantified study on manatee impacts. For the reasons set forth in Part 111(6) above, I agree that, absent waiver, a petitioner challenging an intent to issue a permit may not raise issues at the hearing which were not raised in the pleadings or pre-hearing stipulations. However, in this case the issue of manatee impacts was raised in the pleadings, and Speer was on notice that it had the burden of proof on that issue. As to the other issues, even if I accepted far the sake of argument that they were not raised in the pleadings or pre-hearing stipulations, Speer failed to timely object to the raising of these issues at the hearing and therefore waived any objection. See Sarasota County and Midnight Pass Society v. Department of Environmental Regulation, 13 FAIR 1727 (DER Final Order, April 4, 1991). Therefore, I reject the above exceptions. Proximity To Class II Waters Speer's Exception No. 2 takes exception to the Hearing Officer's conclusion of law that Speer was required to submit a plan which demonstrated that the marina would not have a negative effect on Class II waters. (C.O.L. Nos. 12 and 13) I do not agree that where a proposed marina site is 8,000 feet from Class II waters and where the site is rapidly flushed as noted in Parts 111(1), (2) and (3) above, that the site is in close proximity with the Class II waters within the meaning of Rule 17-312.080(6), Fla. Admin. Code. Accordingly, I accept this exception and reject the above note conclusion of law. Public Interest Test Speer's Exception No. 4 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurance that the project was not contrary to the public interest. (C.O.L. Nos. 17 and 20) For the reasons set forth in Parts III(4) and (5) above, I reject this exception. Cumulative Impacts Speer's Exception No. 5 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurances that cumulative impacts would not result in water quality violations, and that such assurances could only be provided by a quantified study. For the reasons set forth in Parts III (1), (2), (3) and (6) above, I accept this exception and reject the above noted conclusions of law. Modification Of Permit Conditions Speer's Exception No. 6 takes Exception to the Hearing Officer's conclusions of law Nos. 24-34. These conclusions of law concern questions of the authority of the Hearing Officer and me to modify the conditions of the permit. I agree with Speer that since none of the parties have requested any modifications, these conclusions of law are irrelevant. 18/ Therefore I accept the exception and reject the above noted conclusions of law as irrelevant. Miscellaneous Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that Speer and the Department failed to provide reasonable assurance as to prop dredging and turbidity violations because neither Speer nor the Department sufficiently proved the basis for the one-foot clearance policy. For the reasons set forth in Part III(4) above, I reject this exception. Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that the question of whether mitigation is adequate is a question of law. I agree with the Hearing Officer and reject this exception. See 1800 Atlantic Developers v. Department of Environmental Regulation, 552 So.2d 946, 955 (Fla. 1st DCA 1989).
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that Respondent, Department of Environmental Regulation, enter a Final Order denying the application for a permit to construct the proposed project and denying the request for determination of improper purposes. RECOMMENDED in Tallahassee, Leon County, Florida, this 16th day of June, 1992. DANIEL MANRY Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399 1550 (904) 488 Filed with the Clerk of the Division of Administrative Hearings this 16th day of June, 1992.
Findings Of Fact On August 5, 1980, the Petitioners filed an application for a dredge and fill permit pursuant to Chapters 253 and 403, Florida Statutes, and Chapter 17-4, Florida Administrative Code, as well as for water quality certification pursuant to Chapter 401 of Public Law 92-500, as amended, United States Statutes At Large. On March 20, 1981, the Department gave the Petitioners notice that it intended to deny their application for the permit and notified Petitioners of their right to a hearing pursuant to Sections 120.57, Florida Statutes, which right they chose to exercise. The Petitioners own a tract of land adjacent to and partially within the landward extent of the Suwannee River in Dixie County, Florida. The Department of Environmental Regulation (Department) is an agency of the State of Florida charged with carrying out the mandates of Chapter 403, Florida Statutes, and the rules contained in Chapter 17, Florida Administrative Code, promulgated thereunder. The Petitioners propose to embark on a project involving the dredging of a canal approximately 200 feet long in a generally westerly direction from the navigable portion of the Suwannee River through the river berm into the river swamp or floodplain. Across and perpendicular to the landward end of that access canal the Petitioners propose to construct a boat basin approximately 100 feet wide by 275 feet long in the swamp floodplain. The proposed excavation would be to a depth of 6.25 feet below mean sea level and approximately 9000 cubic yards of fill material would be deposited as-fill in the adjacent swamp floodplain remaining around the boat basin and access canal. A boat ramp would then be constructed into the boat basin. A retaining wall would be constructed around the excavated areas along the north and south property lines of the property owned by the Petitioners. The property to be developed by the Petitioners lies within the landward extent of the Suwannee River in Dixie County and the Suwannee River constitutes waters of the State over which the Department has dredge and fill permitting jurisdiction pursuant to Rule 17- 4.28(2)(a), Florida Administrative Code. The project area lies within an "outstanding Florida water" as defined in Rule 3.041(3)(g), Florida Administrative Code. The river terrace or "berm" on the property immediately adjacent to the navigable portion of the river is caused by the natural deposition of alluvial material. The landward extent of the State waters which are the subject matter of this proceeding cross the property immediately behind this terrace and connect with the navigable portion of the river on an adjacent parcel of property. The proposed dredging operation would connect 37,500 square feet of a dead-end canal system excavated to minus 6.25 feet below mean sea level to the navigable portion of the Suwannee River. The dredging and filling operation would result in the permanent elimination of approximately 2.84 acres of the landward extent of the Suwannee River floodplain which is dominated by plant species listed in Rule 17-4.02(17) , Florida Administrative Code, which define jurisdiction of the Respondent. The proposed dredging and filling will cause and constitute a stationary installation reasonably expected to be a source of pollution. The Petitioners during the course of this application process cleared the subject property at least in part. Prior to that clearing operation, the terrace area was vegetated with bald cypress, blue beech, water hickory and sweet gum, with bald cypress and buttonbush becoming the dominant plant species progressing in a southerly direction along the terrace. Landward of the natural terrace or berm, the cypress-tupelo swamp was dominated by water tupelo, bald cypress, water ash, and buttonbush, all species listed in Rule 17- 402(17), Florida Administrative Code. An additional inspection conducted after the land-clearing operation revealed that the area was again sprouting or revegetating into the same swamp species, with the dominant species being bald cypress. The swamp area in question provides flood protection as well as control of sedimentation by the storing of flood waters and the filtering of sediment and particulates releasing them in a gradual fashion to the river system especially during dry periods when the river level is lower than that of the swamp. This also serves to augment the stream flow in the river itself during such periods. The proposed activity, by removing the trees and other plant species named above, as well as because of the dredging and filling of the swamp floodplain area, would cause degradation of local water quality. The swamp currently contributes to the maintenance of water quality in the navigable river itself by the filtering of sediment and particulates, as well as the assimilating, uptake and transforming of nutrients and other pollutants by the plant species growing on the site. The proposed project would destroy by tree- cutting, and the dredging and filling, this function of the swamp area in controlling pollution and promoting water quality in the river. The river swamp on this parcel of property, as well as on adjacent areas, serves as a habitat, food source and breeding ground for various forms of fish and wildlife. The proposed dredging and accompanying filling of the floodplain area with the associated removal of trees and other plants and increased turbidity would largely eliminate this function on the Petitioners' property and drastically alter the swamp area as a habitat, food source and breeding ground on adjacent areas, particularly downstream of the property. The most notable long-term adverse impact of this project would include excessive turbidity caused by the removal of the subject plant species and the deposition of the fill in the floodplain area. Turbidity would be a special problem during times of excessive rain and high or flood waters in the river and adjacent swamp land. An additional long-term detrimental effect will be excessive nutrient enrichment in the area due to the removal of the filtrative and assimilative functions performed by the trees and other plant life across the entire width of the swamp. As a result the adjacent areas will be unable to fully take up the nutrient load formerly assimilated by the plant life on the project area. The project will thus permanently eradicate the subject area's filtrative and assimilative capacity for nutrients, heavy metals and other pollutants. Because of its physical design and dimensions and tangential exposure to river currents and tidal flow, the proposed canal and boat basin will be characterized by sluggish circulation and will lack sufficient flushing action to maintain water quality at an appropriate level, particularly with regard to dissolved oxygen content. The lack of adequate water exchange or flushing will lead to an accumulation of oxygen-demanding sediment and organic waste in the canal and boat basin. This accumulation results in low-dissolved oxygen content in the water and anerobic conditions, which result in a substantially decreasing ability for the water to support aquatic and other wildlife. The lack of water exchange will lead to an accumulation of nutrients which can result in explosive growth of noxious aquatic weeds. In turn, these weeds grow and decay and contribute through the decay process to the low-dissolved oxygen levels in the canal. Thus, the long-term effects will result in violations of water quality criteria for biochemical oxygen demand, nutrient content and dissolved The cumulative effect of a proliferation of projects such as this one involving dredging of canals and associated filling, as well as filled roads across similar floodplain areas, will cause degradation of local water quality in violation of State standards both singly and in the aggregate. Such a project ultimately alters the hydro-period of the area, which is the average time during which flood waters are retained in the swamp and floodplain area for gradual, filtered release into the river itself. The altered hydro-period will result particularly from the removal of trees and other plant species which perform a filtrative function for flood waters and associated sediment. The removal of the plant life will result in a more rapid flow of waters through the subject swamp area which will prevent sediments from precipitating out of the water before it returns to the navigable river which effect will be heightened by the presence of the turbidity caused by the deposition of the fill material and its exposure to the erosive effect of flood waters. The Petitioners additionally failed to show that the project was necessary in order for them to have access to the navigable portion of the river. The Department advocated prior to and during the hearing that a viable and acceptable alternative would be the construction of a walk-way or a bridge on pilings across the jurisdictional area in question connecting the two upland portions of the Petitioners' property. Although the bridge or walkway would require a permit, the Department took the position that it would not object to such a permit for an elevated wooden walkway and dock into the navigable portion of the river or a bridge for vehicles and an attendant boat ramp. The Petitioners did not agree to such a solution of the controversy. It should also be noted that access is available for the Petitioners to the waterward portion of the property from the navigable side of the river berm by boat. The Petitioners contend they are entitled to a permit by default on the part of the Respondent. The Department received the application on August 5, 1980. Three days later on August 8, 1980, the Respondent requested additional information and informed the Petitioners that they had to present evidence of consent to the use of the State-owned land involved from the Board of Trustees of the Internal Improvement Trust Fund/Department of Natural Resources (DNR). The application was forwarded to the DNR on September 8, 1980. Another copy of the application was forwarded to the DNR on January 8, 1981. A letter from DNR to the Petitioners on approximately March 9, 1981, indicates that the application was held in abeyance pending notification of action by the DER, the Respondent herein. Ultimately, the DNR by letter of March 19, 1981, acknowledged receipt of payment for the subject fill material, but elected not to formally consent or reject the project. It has been the practice of the Respondent Department to await a DNR consent or rejection prior to issuance of its notice of proposed agency action. The Department issued its intent to deny by letter on March 20, 1981, which was 43 days after the Petitioners' last modification of its application on February 5, 1981. Thus, the application was not complete until February 5, 1981, since the Petitioners never furnished the lawfully requested information until that date.
Recommendation Having considered the foregoing-findings of fact, conclusions of law, the candor and demeanor of the witnesses and the pleadings and arguments of counsel, it is therefore RECOMMENDED that the petition of Raymond H. Hodges, Jr., and Anne G. Hodges for a dredge and fill permit be DENIED. DONE AND ENTERED this 16th day of October, 1981, in Tallahassee, Florida. P.
