Findings Of Fact This cause commenced upon the filing of an application (#440816855) by William O. Reynolds to construct a weedgate and fence in front of a dead-end canal in Bogie Channel serving the Atlantis Estates Subdivision on Big Pine Key, Monroe County, Florida. The proposed project would be constructed in Class III waters of the State of Florida. An existing unpermitted weedgate exists in this location and the applicants for the proposed project are attempting to obtain a proper permit for a modified version of the existing gate. Applicants for the proposed project are property owners in the Atlantis Estates Subdivision, whose properties are adjacent to the canal in front of which the proposed weedgate and fence are to be located. An ad hoc committee of certain of the Atlantis Estates Subdivision owners had met and decided to proceed with an application for the proposed project. However, not all subdivision landowners agreed with the proposed project, most specifically the Petitioners Margaret and J. A. Abbanat. William Reynolds signed and submitted the application for the project, and indicated in a notarized affidavit in tie application that he was acting as agent for property owners in the Atlantis Estates Subdivision. Reynolds is one of those property owners, specifically lot #17. There are 26 lots adjoining the dead-end canal. At hearing, twenty (20) of the property owners indicated their support for the project by submission of notarized statements. The members of the ad hoc committee and the vast majority of property owners authorized and supported the project and the filing of the application by Reynolds. The permit application for the proposed weedgate and fence was submitted due to the problems caused by dead floating sea grasses and weeds (wrack) collecting in the Atlantis Estates Subdivision canal. Wrack has collected in large quantities in the canal in the past, and at such times problems such as stench, difficulty in navigation, and fish kills have occurred. Accumulated wrack in dead-end canals can cause water quality problems, including fish kills, and may also negatively affect navigation in the canal. Wrack is likely to collect in the Atlantis Estates Subdivision canal due to its dead-end configuration and due to its location, since the open end of the canal faces the east and the prevailing winds in this area are from the east. The weedgate and fence should cause no state water quality violations, should not unreasonably interfere with navigation where it is located at the mouth of the canal, and should actually improve water quality and navigation within the canal. Water quality outside of the weedgate and fence should not be significantly decreased since the winds, tides, and currents should allow the wrack to drift away into open water and not accumulate, especially not to the extent the wrack would accumulate in the canal. According to a proposed DER permit condition, the weedgate and fence must not cause a state water quality violation, and therefore if a water quality violation were caused by the project in waters outside the weedgate and fence, enforcement action would be required to correct the problem. If the weedgate and fence becomes a navigational hazard, it is to be removed according to a proposed DER permit condition. The application was not certified by a Professional Engineer. The Department's South Florida District Office did not seek such a certification from the applicant. The proposed project consists of a stainless steel framework with vinyl covered wire fence to prevent wreck from drifting into the canal and a gate through the fence constructed of the same type of materials with a cable and counter weight system for opening and closing the gate. As proposed, the weedgate and fence should not create a navigational hazard, but should that occur, the proposed DER permit condition would require removal.
Recommendation Based upon the foregoing Findings of Fact, and Conclusions of Law, it is, therefore, RECOMMENDED that the State of Florida Department of Environmental Regulation grant the application and issue the permit subject to the following conditions: That the weedgate and fence be removed if at anytime a navigational hazard develops or the structure fall into disrepair. That the weedgate and fence must not cause a state water quality violation outside of the fence and if such water quality violations were caused by the project in water outside the weedgate and fence, enforcement action would follow.

Findings Of Fact Respondent, George M. Threadgill, applied on May 5, 1982, for a dredge and fill permit under Chapter 403, Florida Statutes, and Chapter 17-4, Florida Administrative Code. The application was for an extension to an existing pier which would be approximately 100 feet long by 4 feet wide with a platform on the end which would be approximately 10 feet long by 14 feet wide. On May 11, 1982, Respondent modified the application by adjusting the angle of the pier extension so it would not extend in front of his neighbor's property. The site of the project was to be on Innerarity Point on Perdido Bay, Escambia County. The existing pier is approximately 90 to 100 feet long. Prior to Hurricane Frederick in September, 1979, the existing pier extended an additional 40 feet into Perdido Bay. The Department of Environmental Regulation is an agency of the State of Florida with jurisdiction under Chapters 403 and 253, Florida Statutes, to regulate and require a permit for the construction of stationary installations within waters of the State. The Department also has permitting jurisdiction over dredge and fill operations in such waters pursuant to Florida Administrative Code Rules 17-4.28(2) and 4.29(1). The water at the project site is extremely shallow. Witnesses O'Neil and George Threadgill established that the water at the end of the existing pier ranges in depth from being dry in the winter to approximately 2 feet 6 inches during normal water levels. At the end of the proposed pier, the water is from 2 feet 9 inches deep to "waist deep" during normal water levels. There are no grass beds or other areas of significant marine vegetation in the area of the project. Expert witness Snowdon demonstrated that the bay bottom in the area consists of various grades of sand. There are no lagoons or inlets on the adjacent shoreline, and there are no navigational channels in the vicinity of the Project area. The construction of the pier extension is not expected to interfere wish wildlife in the area. There will be some amount of turbidity introduced into the water column as a result of placing the pier pilings in the water. Coarse sand of the type found in the area will settle rapidly out of the water column. Significant water quality problems would only be encountered if pockets of sediment are encountered while "jetting" the pilings into the substrate. The use of turbidity control measures will alleviate water quality problems associated with construction. Based on unrefuted expert testimony of witnesses Snowdon and Fancher, no water quality degradation will occur during and after construction of the pier. The majority of boat traffic in the area consists of mullet fishermen. The mullet boats navigate in the project area, but, as even Petitioners admit, they generally run either around or waterward of an iron stake located approximately 500 feet from shore. When the mullet boats do come within the project site, it is merely to pass through. They do not set their mullet nets within the project area. The existence of the pier will not significantly interfere with navigational patterns for commercial and private fishermen, nor for other types of marine craft or purposes. A sandbar approximately 20 to 25 feet wide exists along the shoreline beginning approximately 10 feet in front of the applicant's existing pier. Prior to September, 1979, the existing pier extended past the sandbar. There was no evidence presented that the pier blocked access or navigation at that time. The Petitioners do not object to the pier being rebuilt to its pre-1979 dimensions, nor to an area beyond the sandbar. At normal or high tide, Petitioners are able to run their boat straight out into Perdido Bay from a distance of 60 feet from the shore due to their having a "short shank motor" on their boat. The existence of the pier across the sandbar will not significantly interfere with the Petitioners' access to their pier or their waterfront. The existence of the pier will not affect navigational patterns of other neighbors. Paddleboats use the waters in the vicinity of the project area. Paddleboats can navigate under the adjacent pier owned by the Petitioners. The adjacent pier is approximately 5 feet high as measured from the top of the pier to the sand bottom. The proposed pier will measure slightly less than 6 feet from the top to the sand bottom. The existence of the proposed pier extension was thus shown to not significantly disrupt recreational paddleboat navigation in the area.
Recommendation Having considered the foregoing findings of fact and conclusions of law, the evidence in the record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, therefore, RECOMMENDED that the application for a dredge and fill permit by George M. Threadgill for the construction of an extension to his existing pier on Innerarity Point in Perdido Bay in Escambia County, Florida, be GRANTED and that the necessary permit be issued.

Findings Of Fact On December 12, 1991, Petitioner applied to the Respondent for a permit/water quality certification to grade and level, in stages, approximately 20,000 square feet or 0.45 acres of lake front to remove and prevent the formation of berms and depressions in the exposed lake bottom adjacent to his property. The project site is located at 3955 Placid View Drive which lies along the shoreline of Lake Placid, a natural waterbody in Highlands County, Section 24, Township 37 South, Range 29 East. Lake Placid is not an aquatic preserve, and is not an outstanding Florida water. It has been designated as a Class III waterbody. Petitioner's unsubdivided lot lies at the western end of Lake Placid. The shoreline measures approximately 203 feet. The western lot line also measures 203 feet, and fronts on Placid View Drive. The water level of Lake Placid has receded in recent years which allows large expanses of what was historically lake bottom to become beaches, lawns, and areas of habaceous marsh. The specific project which the Petitioner proposes calls for the leveling of the berms and depressions which form on the exposed lake bottom from collected water, which stagnates and permits various noxious creatures, including mosquitoes, to breed in them. The berms and depressions are approximately six inches high or deep and between one and three feet wide, and generally extend the length of the shoreline. The proposed area affected is approximately 20,000 square feet or 0.45 acres of lake front, although Petitioner proposes to actually level a much smaller area in stages of approximately 2,000 square feet on an "as needed" basis. No material other than sod in the beach area is proposed to be brought from or removed to off-site locations. Petitioner is highly sensitive to mosquito bites. The area proposed for leveling was previously cleared of vegetation without authorization. Very little revegetation of the shoreline has occurred since the area was cleared. Vegetation colonizing the beach, at present, includes pennyworts (Centella asiatica and Hydrocotyle umbellata) and water- hyssops (Bacopa sp.) Blue green algae was observed in the depressions which have formed along the shore since the clearing. Fauna observed on-site included gulls (Larus sp.), small fish in the adjacent lake shallows, and water-boatmen (Order Hemiptera) in the depressions. An area landward of the wetlands considered here was also cleared previously and is proposed to be seeded. An adjacent, uncleared shoreline was vegetated with primrose willow (Ludwigia sp.), cattail (Typha sp.), flat sedge (Cyperus odorata), and other wetland species for an almost 100% plant coverage. The Petitioner proposes to use a small tractor in leveling of the shore which will cause turbidity in the lake water. No turbidity controls were proposed by the Petitioner. Petitioner failed to provide reasonable assurances that the turbidity caused by the earthmoving equipment in areas presently above water would not cause degradation of water quality in Lake Placid; would not contribute to the long-term degradation of water quality in the lake caused by upland runoff that would flow into the lake without benefit of retention or filtration by shoreland vegetation (freshwater herbaceous habitat) which would be permanently removed under Petitioner's proposal. Nutrients such a nitrogen and phosphorus and pollutants such as pesticides, herbicides and other chemicals commonly used in lawn and garden care would be included in the runoff, and would have an adverse impact on fishing and marine productivity in the lake. The project would have a minor adverse impact on erosion and soil stabilization in the area surrounding the lake. Petitioner has failed to provide reasonable assurance that the proposed project is not contrary to the public interest. Petitioner can mitigate the project by eliminating the use of heavy equipment and substitute hand equipment to smooth out ruts, berms and depressions in jurisdictional areas.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Petitioner's application for Wetland Resource Regulation permit be DENIED.

Findings Of Fact Background Respondent, Deep Lagoon is the owner and developer of real property contiguous to state waters in the Caloosahatchee River at Fort Myers, Lee County, Florida. When Deep Lagoon purchased the property in 1980, the marina had been in existence for an extended period of time. An aerial photograph (Petitioner's Exhibit 18) shows a marina at this location in February 1966. The owners of Deep Lagoon represented at hearing that there are photographs of a marina in this location in 1955. The present owners have improved the facilities and continue to operate a full service marina on site. The existing site plan (Deep Lagoon's Exhibit 3) shows that the project contains three canals: the northern canal, main canal, and southern canal. There is a basin at the eastern end of the main canal. The uplands beyond the northern canal are part of a residential development known as the "Town and River" area. The finger peninsula between the northern and main canal is known as the east-west peninsula. The smaller land area northeast of the southern canal and south of the basin is referred to as the marina dealership and boat storage area. This last area is adjacent to McGregor Boulevard. The marina waters are designated as Class III waters by the state. Deep Lagoon Marina is in Deep Lagoon, a natural, mangrove-lined, deep channel in the south shore of the river. The three canals which are part of the marina, are the result of historic dredge and fill activity which created most of the uplands west of McGregor Boulevard. Except for the Iona Drainage District ditch which discharges into the northern canal, the canal water system is a dead-end system with little circulation from a hydrographic standpoint. Generally, the water sloshes back and forth within the canal system. As a result of poor water circulation within the system, sediments have built up in the canal bottoms and in the basin. Although different historical incidents, such as ship building, the burning of a large building on the east- west peninsula and the receipt of agricultural and highway drainage into the northern canal, may have caused some of the build-up, marina activities and the use of the canals for marina purposes have contributed significantly to the problem. Water quality samplings within the canals and basin indicate that State Water Quality Standards are currently being violated for dissolved oxygen, oils and greases, total and fecal coliform, copper, lead, mercury and tributylin. Sediments in the canals and basin are contaminated by lead, copper, cadmium, chromium and mercury. The canals and basin are currently devoid of seagrasses, oyster beds and benthic organisms. The West Indian Manatee, an endangered species, inhabits the Caloosahatchee River. Manatees are frequently seen in the Deep Lagoon area and are found within the northern canal of Deep Lagoon Marina. Since the marina was purchased by its current owners, maintenance of the property has improved. The management has demonstrated a responsible approach to many environmental concerns that are usually associated with marinas. For example: Gas attendants pump fuel to reduce gasoline spillage. The marina's mechanical work is confined to one area in order to maintain clean up controls. Boat cleaning is done with water only. Boats are repainted with a low copper-based paint to reduce the harmful effects of paint leaching on water quality. On December 9, 1986, Deep Lagoon applied to DER for a permit to renovate and expand the existing marina operation. The application was completed on March 7, 1988. The application, Deep Lagoon's Exhibit 1, consists of a proposal to: (1) rehabilitate the existing 61 wet slips and construct 113 new wet slips, which include 14,440 square foot of docks and boardwalks in the northern and southern canals, as well as the main basin; 2) excavate material for a circulation channel between the main basin and northern canal; 3) dredge contaminated sediments from the canals and the basin; and 4) place clean fill material within the canals and basin to replace the dredged fill, and to create a more shallow canal system for circulation and flushing purposes. In addition to the proposals initiated by Respondent Deep Lagoon, the Intent to Issue requires Deep Lagoon to: 1) construct a stormwater treatment system; 2) redesign and construct the boat wash area so that all runoff is directed to a collector and filtering system; 3) relocate and upgrade existing fuel facilities; 4) install an oil/fuel containment system; and 5) install sewage pumpout facilities. To alleviate concerns about the proposed project's effect on manatees, Respondent Deep Lagoon has worked with state and local governments to develop a manatee protection plan for the surrounding portions of the Caloosahatchee River. The Department of Natural Resources reviewed the plan, and recommended issuance with the restriction that the use of the additional slips be limited to sailboats until the manatee protection plan is enacted and enforced. The Respondent Deep Lagoon has agreed to accept all of the additional requirements and recommendations placed upon a dredge and fill permit by Respondent DER and the Department of Natural Resources. The Respondent DER has permitting jurisdiction under P.L. 92-500, Chapter 403, Florida Statutes, and Rule 17-12.030, Florida Administrative Code. Deep Lagoon constitutes waters of the state over which DER has dredge and fill permitting jurisdiction. In its review of Respondent Deep Lagoon's application for a dredge and fill permit, Respondent DER applied Section 403.918(2)(b), Florida Statutes, which provides that where existing ambient water quality does not meet standards, a permit may be issued if the applicant can demonstrate that the project will cause a net improvement of the water quality for those parameters which do not meet standards. The conditions placed upon the permit allow Deep Lagoon to construct all of the additional boatslips requested in a one-phase construction project. Fifty-six of the additional wet slips can be occupied immediately. The types of boats placed in these slips will be determined by the outcome of the proposed manatee protection plan. If the plan is enacted and enforced, motorboats may be placed in these slips. Until this occurs, only sailboats can be placed in these slips. If water quality monitoring shows that there has been a significant net improvement at the end of a year of the additional wet slip use, the remaining 57 slips may be occupied. The results of the water monitoring will be compared with water quality tests to be taken before construction or renovation begins for baseline water quality study purposes. Water quality monitoring will continue for two years after the marina reaches 80 percent occupancy, or until a year after increased motorboat occupancy is allowed. If monitoring continues to show a net improvement in water quality over baseline conditions, the slips shall be considered permanent. If a net improvement is not demonstrated for either phase, Deep Lagoon is required to present a possible solution to DER. No remedial action shall be taken without DER approval. DER may require slip removal if other remedial action is not successful. The total cost to the marina for the expansion project is estimated to be about 3.7 million dollars. Net profit for the marina is expected to increase from one hundred and six thousand dollars ($106,000.00) to three hundred and fifty to four hundred thousand dollars ($350,000.00 to $400,000.00) annually. The Petitioners are the owners of single family homes within the "Town and River" area, which is adjacent to the north of the proposed expansion and renovation project. The Petitioners dispute the appropriateness of the Intent to Issue filed by Respondent DER on July 17, 1988. In support of their position, the Petitioners identified a number of areas of controversy which they contend should cause the Respondent DER to reverse its preliminary decision to grant the dredge and fill permit on this project. These areas of controversy are: Whether the proposed activity complies with the water quality requirements of Section 403.918(1), Florida Statutes, and the federal antidegradation regulation, 40 CFR Section 131.12, which the Petitioners contend is applicable to this case pursuant to the Clean Water Act water certification. Whether the proposed project complies with the public interest criteria set forth in Section 403.918(2)(a), Florida Statutes, and whether it will adversely affect the West Indian Manatee, an endangered species. Whether the proposed manatee plan and water quality mitigation proposal meet applicable statutory and rule criteria. Whether the proposed project will cause unacceptable and unpermittable cumulative impacts and secondary impacts, pursuant to Section 403.919, Florida Statutes and other applicable law. Whether DER can certify this project pursuant to 33 USC Section 1341 of the Clean Water Act when water quality standards will not be met in the waters of the Deep Lagoon Marina. Whether the permit condition of a "net water quality improvement" is a vague and unenforceable condition. The Intervenor has intervened in the Petitioner's formal administrative proceeding for a factual determination as to whether the proposed project will adversely affect the conservation of the West Indian Manatee by direct, secondary or cumulative impacts. Water Quality The testing results from the water quality samplings taken for purposes of permit application review, may not accurately represent the mercury number at all the sampling sites. The zinc number from the samplings taken in the northern canal (which receives discharge from the Iona Drainage District ditch) is so high that the number may not be an accurate representation of the zinc content in the water column at this location. The water samplings taken, and the future samplings to be taken for baseline purposes, do not take into consideration the following variables: a) that there are two distinct seasons in the area, wet and dry; and b) that the marina is not a completely closed, dead-end system. The Iona Drainage District ditch occasionally overflows or discharges into the northern canal. Expert opinion presented at hearing established that: a) baseline sampling should include control sites on the eastern side of the berm of the Iona Drainage District ditch, which is not owned by Respondent Deep Lagoon; and b) baseline samplings should be taken during the two seasons. Wet season samples should be compared against the wet season baseline, and dry season samples should be compared against the dry season baseline. Short term water quality impacts of the proposed project include the potential for limited turbidity generated by dock construction, excavation of the contaminated sediments and circulation channel, and the shallowing of the canals. The installation and use of turbidity curtains around the entire construction area during the construction, dredging, and shallowing should limit the short term violations regarding water turbidity. The overall increase in water quality which will be gained upon the removal of contaminated sediments in conjunction with the creation of a better flushing system within the marina complex, is in the public interest and far outweighs any temporary impact on turbidity, which will be minimized by the turbidity curtains. Oils and Greases It is impossible to determine all of the source of oil and greases found in the waters surrounding Deep Lagoon. Stormwater from the uplands area may bring oil and greases into the northern canal waters from the Iona Drainage District ditch, which appears to receive stormwater runoff from the adjacent highway and the fueling facilities at the adjacent 7/Eleven Store. However, historic fueling operations at the marina site, and the current marina operations have contributed significantly to the accumulation of oil and greases in the entire canal system. The proposed stormwater treatment system at the marina, which has already been permitted, is expected to reduce the amount of oils and greases which will enter the waters from the marina site. The runoff from the land operations, such as boat fueling, servicing and boat washing, and automobile parking, will be directed into various collectors for treatment within a stormwater treatment system prior to discharge into the waters of Deep Lagoon. The designer of the system anticipates that the amount of oils and greases entering the waters of the land operations will be reduced by 90-95 percent. It has not been determined if the new cut in the easterly portion of the east-west peninsula will affect the water exchange between the northern canal, the basin, and the Iona Drainage District ditch. Total and Fecal Coliform The total and fecal coliform in the waters of Deep Lagoon Marina are due primarily to the presence of these pollutants in the stormwater runoff from upland areas of the marina facility. Other potential sources of total and fecal coliform are improperly functioning septic tanks and drainfields at the marina facility, and discharges from marine toilet facilities on boats using the marina. Deep Lagoon will install an on-site central sewage collection and transmission system that will eliminate the use of the septic tanks and drainfields. All sewage from the collection and transmission system will be discharged into the system of a private utility company for treatment off-site. Deep Lagoon is required to install a sewage pumpout facility for use by boats with marine toilet facilities, thereby minimizing discharges from these on board toilet facilities into the waters of the marina. In addition, every boat slip occupied by a liveaboard vessel at the marina will have a permanent direct sewage connection to the central sewage collection system. As a result of the construction of the stormwater treatment system, the elimination of the septic tanks and the construction of a central sewage system, and the installation of sewage pumpout facilities, there will be a reduction in the levels of total and fecal coliform in the waters of Deep Lagoon Marina. Copper The principal source of cooper in the waters of the Deep Lagoon Marina is runoff from the boat cleaning and painting operations at the marina facility. An additional significant source of copper to these waters is the bottom sediments which are highly enriched with copper from past marina operations at this location. Copper and other metals, including lead and mercury, enter the water column through leaching from the sediments and the suspension of the bottom sediments caused by the movement of boats within the marina. Minor sources of copper to these waters include brass or bronze fittings on vessels and leaching from antifouling bottom paints of boats and treated pilings used to construct docks. Pursuant to the Intent to Issue, Deep Lagoon is required to hydraulically dredge the top six to twelve inches of contaminated sediments from substantial portions of the northern and southern canals and the main basin. Due to the construction of the stormwater treatment system and the removal of the contaminated bottom sediments, there will be a reduction in the levels of copper in the waters of Deep Lagoon Marina. However, this will occur only if the copper does not return to the water through a leaching process caused by soft rainwater. Limestone, or calcium carbonate is necessary in the stormwater treatment soil to prevent leaching. Such conditions were not demonstrated at hearing. The anticipated increased levels of dissolved oxygen in these waters will also decrease copper concentrations in the water column by increasing the tendency for dissolved copper to become insoluable, settle out and become trapped in the sediments. This reduction in copper concentrations will offset any minor increased loading of copper concentrations through leaching from the bottoms of the additional boats expected to utilize the expanded marina. Lead The primary source of lead to these waters is from past use of leaded gasoline and its residues, which enter the water from stormwater runoff. It is impossible to determine all of the sources of the stormwater runoff due to the entry of the Iona Drainage District ditch into the northern canal during certain stormwater events. Lead also enters the water column of these waters from the contaminated bottom sediments. As a result of the construction of the stormwater treatment system, the dredging of the contaminated bottom sediments, and the reduction in use of leaded gasoline, by all boaters and automobiles, there will be a reduction in the levels of lead in the waters of the Deep Lagoon Marina. Mercury Other than the contaminated sediments themselves, there is no apparent source of mercury in these waters. The removal of the contaminated sediments will result in a reduction in the levels of mercury found in these waters. Zinc Even if the water quality data for zinc at the one sampling station previously mentioned is accurate, the construction of the stormwater treatment system, and the dredging of contaminated bottom sediments should cause a net improvement in the quality of these waters by reducing the zinc content. Dissolved Oxygen The decreased levels of dissolved oxygen in the waters of Deep Lagoon Marina are due principally to biochemical oxygen demanding substances that enter the water column from stormwater runoff. The runoff is mainly from the marina uplands, but also includes the Iona Drainage District ditch. Contaminated sediments also exert biochemical oxygen demands on the water column of these waters. The discharge points of the stormwater treatment system will be constructed so as to produce a cascading effect on the discharged water. This cascading effect will introduce additional dissolved oxygen to the waters of Deep Lagoon Marina. Deep Lagoon is required to excavate a circulation channel to connect the northern canal and the main basin. Deep Lagoon is also required to shallow the northern canal -5.6 ft. NGVD and the southern canal and main basin to -.6.6 ft. NGVD. The excavation of the flushing channel and the shallowing of these waters will improve the flushing of the water circulation of the Deep Lagoon Marina. The construction of the stormwater treatment system, the cascading effect of the stormwater discharge points, the removal of the contaminated sediments, the excavation of the circulation channel, and the shallowing of the canals and basin will result in a net improvement in the levels of dissolved oxygen in the water of Deep Lagoon Marina. Tributyltin Tributyltin is a toxic compound formerly used in paints used to maintain the bottom of boats. Levels of tributyltin in the waters of the Deep Lagoon Marina are in violation of the state "free-form" standards. The proposed project, with all the required modifications will result in a reduction in the levels of tributyltin in these waters. When the sediments are dredged from the marina bottoms, samples need to be subjected to an EPA toxicity test to determine whether the sediments have become hazardous through the dredging process. If the sediments have become hazardous, they must be disposed of through a hazardous waste facility. If the fill material used to shallow the marina bottoms comes from the area excavated for the flushing channel, this soil should be tested to determine if it is "clean fill." The area where the cut will be made has been used for boat sanding in the past, and may contain contaminated materials. The evidence presented at hearing has demonstrated that the dredging, the new water circulation and flushing design for the marina, and the stormwater treatment system will cause a net improvement in water quality once renovation and expansion of the marina is completed. The effect of stormwater discharge from the Iona Drainage District ditch into the northern canal is not known at this time. The effect of the new water circulation and flushing patterns on the berm between the drainage ditch and the northern canal is not known at this time. Public Interest Standard - Section 403.918, Florida Statutes Regarding the criteria listed in Subsection 403.918(2), Florida Statutes, the parties have stipulated as follows: The proposed project will not adversely affect navigation or the flow of water or cause harmful erosion or shoaling. The proposed project will be of a permanent nature. The project will not adversely affect significant historical or archaeological resources. The evidence shows that the adjacent waters of the Caloosahatchee River support manatees year round with a large over-wintering population. The Caloosahatchee River has been designated as critical habitat for the West Indian Manatee, an endangered species. The Department of Natural Resources Bureau of Marine Resources studies have shown that approximately twenty- five percent (25%) of manatee deaths are due to boat collisions. The proposed expansion of this marina would increase boat traffic in an area of heavy manatee usage. It was established that manatees are found more often in the shallower areas of the river, outside of the main channel. Deep Lagoon has been instrumental in providing manpower and financial resources for the preparation of the Caloosahatchee River Boat Operation and Manatee Protection Plan. The principal goal of the plan is to protect the manatee in the Caloosahatchee River by regulating the speed of boats outside the marked channel and a buffer zone of the Caloosahatchee River. (Deep Lagoon Exhibit 5). The plan has received support from the Department of Natural Resources, and is currently being reviewed by the Lee County Board of County Commissioners for preparation of the plan. Pursuant to DER's Intent to Issue, the plan is to be considered a part of the proposed permit. Occupancy of the additional 113 wetslips is restricted to sailboats until such time as the plan is implemented and enforced on the Caloosahatchee River. Upon demonstration to the Department that the plan is being implemented and enforced, Deep Lagoon may increase the powerboat occupancy of the marina up to a maximum of 75 percent of the total allowed occupancy. It was established that one of the principal threats to manatees is from fast moving powerboats. By controlling the speed of boats in those areas where manatees are most frequently found, the river can tolerate more boats and still not harm the manatees. Without the implementation and enforcement of the plan, the proposed project with its projected increased number of boats would likely result in an increase in the number of boat kills of manatees if the additional boats are powerboats. However, if the plan is implemented and enforced, the proposed project at Deep Lagoon, including additional upland storage of boats, will not have negative impact on the manatee, even when considering the cumulative impacts of other existing and proposed boating facilities. If only sailboats are allowed in the additional slips, the proposed project will not negatively impact the manatee population. In addition to the plan, through the conditions of the Intent to Issue, Deep Lagoon has agreed to enter into a long-term agreement to limit powerboat occupancy at the marina to a maximum of 75% of the total 174 wetslips. Deep Lagoon has also agreed to operate all vessels associated with the construction of the project at "no wake/idle" speeds at all times while in water where the draft of the vessel provides less than three feet clearance from the bottom and has agreed that vessels will follow routs of deep water whenever possible. Deep Lagoon has agreed that all construction activities in open water will cease upon the sighting of manatees within 100 yards of the project area. Construction activities will not resume until the manatees have departed the project area. Deep Lagoon has agreed to install and maintain manatee awareness signs at permanent locations within the construction area. Furthermore, Deep Lagoon has agreed to establish and maintain an educational display at a permanent location to increase the awareness of boaters using the facility of the presence of manatees, and the need to minimize the threat of boats to these animals. In addition to the above, Deep Lagoon has agreed to make available: (a) one wetslip for use by the Florida Marine Patrol; (b) one dry slip for the Lee County Sheriff's Department; and (c) upland space for the Coast Guard Auxiliary. Cumulative and Secondary Impacts There is no affirmative evidence in the record concerning the consideration given to existing and proposed marina projects in the Caloosahatchee River by DER in its review of Deep Lagoon's application for a permit. However, conditions placed in the permit which require sailboats only in the additional boatslips, along with educational displays regarding manatees, necessarily imply that the cumulative and secondary impact review took place.
Recommendation Based upon the findings of fact and conclusions of law, it is RECOMMENDED: That the Respondent, Department of Environmental Regulation, grant the applicant, Deep Lagoon Marina, a dredge and fill permit, pursuant to the Notice of Intent to Issue dated July 26, 1988, in File No. 361279929, provided that the following additional conditions are incorporated into the permit as mandatory conditions: Baseline water quality samples include a sample site east of the berm between the Iona Drainage District ditch and the northern canal and assure that future water quality decline is not caused by discharge into the northern canal from the drainage ditch. A multiple baseline sampling shall be taken, consisting of one wet season and one dry season baseline. Comparative reviews shall be done of future wet season samples against the dry season baseline. When sediments are dredged from the marina bottoms, samples from each canal and the basin are to be subjected to an EPA toxicity test to determine whether the sediment is hazardous, and requires disposal at a hazardous waste facility. If the fill material used to shallow the marina bottoms comes from the area excavated for the flushing channel, it is to be tested to determine that it does not contain contaminated materials which will reduce the improvement in water quality gained from the dredging process. If the manatee protection plan ultimately adopted within the river is different than the plan referenced in the Intent to Issue, Deep Lagoon may not increase its power boat usage unless a permit modification is approved by the DER. If a manatee protection plan is not adopted and enforced, the additional slips should be occupied only by sailboats until such time as the manatees are actually granted protection. Limestone shall be placed within the stormwater treatment system if the available soils are deficient in the calcium carbonate to be used to precipitate copper back out of the stormwater discharge system.

Findings Of Fact On January 19, 1984, Applicant applied to DER, pursuant to Sections 253.123 and 403.087, Fla.Stat., and Chapters 17-3 and 17-4, F.A.C., for a permit and water quality certification to construct a 36-slip docking facility in Baker-Carroll Pointe Waterway (the lagoon). While the lagoon is located in Class II waters, the waters are prohibited for shellfish harvesting. On October 31, 1984, DER issued its letter of intent to issue the requested permits. Protestors timely filed a petition for formal administrative proceedings. Protestors' substantial interest will be directly affected by issuance of the subject permit. The proposed facility will be located as close as 50 feet to the main residential building of Protestors, and the proposed docks will be accessed by way of a seawall which is part of Protestors' common area. The Marina The permit sought by the Applicant would allow it to construct a 36- slip docking facility consisting of 615 linear feet of 5 foot wide marginal dock set 6 feet waterward and running parallel to an existing concrete seawall, with three 5 foot by 6 foot access ramps from the seawall to the marginal dock, and eighteen 30 foot by 4 foot finger piers extending waterward of the marginal dock. Nineteen mooring piles are to be installed. Total dock area is to be 5,325 square feet. The facility will be constructed of pressure treated piles and lumber. No fuel facilities are proposed. Applicant proposes to sell the 36 slips to unit owners in the Surf Colony complex, that is Vanderbilt Surf Colony I, Vanderbilt Surf Colony II and Vanderbilt Surf Colony III, and, if and when constructed, Vanderbilt Surf Colony IV and V. Each of the existing buildings contains 65 units. DER's October 31, 1984, letter of intent, proposed to issue the permit subject to the following conditions: Turbidity screens shall be utilized and properly maintained during the permitted construction and shall remain in place until any generated turbidity subsides. The lagoon shall be designated a "No Wake" zone. Markers and/or signs (PVC pipes or piles) shall be erected at the entrance to the shallow cove prohibiting navigation in said area with limits to be approved by the Punta Gorda DER office. No liveaboards shall be allowed at the permitted facility. No boat cleaning, hull maintenance, nor fish cleaning shall be allowed at the permitted facility. Trash receptacles shall be located at approved locations on the dock. The easternmost dock limit shall be lighted at night or equipped with reflective markers to aid navigation. No construction of the project shall take place until appropriate DNR approval is granted for the project per Section 253.77, Florida Statutes. The project shall comply with applicable 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. Applicant has agreed to comply with all conditions established by DER. The Marina Site Baker-Carroll Pointe Waterway (the lagoon) is a partially man made navigable lagoon, with access to Water Turkey Bay which lies to its east. The south side of the lagoon is bulkheaded (along the proposed docking facility site), and the north and west side of the lagoon is composed of dense mangrove forest within the Delnor-Wiggins Pass State Recreation Area (Park). The waters of the proposed project abut and mix with those of the Outstanding Florida Waters (OFW) of the Park. Rule 17-3.041(4)(c), F.A.C. The Park is located on the western and northern shores of the lagoon, and the Park's boundary is located underneath the existing lagoon. The Park has a boat ramp and dock at the mouth of the lagoon. Associated with the ramp are 36 parking spaces for boat trailers. The access channel from Water Turkey Bay varies from 100 to 150 feet wide, the end of the lagoon is approximately 200 feet wide, and the lagoon is approximately 700 feet long. The bulkheaded shoreline has a shallow, 6 foot wide shelf that is covered by a few inches of water during low tide and is colonized by oyster assemblages. Depths increase rapidly from the edge of the shelf to -7 to -8 feet NGVD approximately 40 feet offshore. Depths at the finger piers will be -4.5 to -6.5 NGVD feet. The majority of the central lagoon has uniform depths of -7 to -8 feet NGVD with approximately one foot of silt overlying a firm substrate. Increased depths of -9 to -10 feet NGVD are found in the channel leading from the lagoon to Water Turkey Bay. Channel depths within Water Turkey Bay are -5 feet NGVD or less. Except for a shallow cove at the northwestern extreme of the lagoon, water depths of -5 to -7 feet NGVD are found approximately 30 feet waterward of the mangrove fringe along the western border of the lagoon. In the immediate project site there are no seagrasses or other significant biota. The only productive area within the project site is the shallow six foot wide shelf which parallels the bulkhead and is colonized by oyster assemblages. There are no other significant biota because the area was extensively dredged in the late 1960s or early 1970s. Seagrasses are found in the smaller cove located in the extreme northwest of the lagoon. The western and northern shores of the lagoon are extensively populated by red, black and white mangroves. Aquatic fauna known to inhabit the vicinity, and found in association with the grassbeds in Water Turkey Bay, include lightening whelks, blue crabs, sheepshead minnows, mullet, pin fish, and silver perch. Areas of Concern During construction of the marina elevated turbidity may be expected by disruption of the lagoon sediments caused by installing the facility's pilings. This can, however, be adequately controlled by the use of turbidity curtains during construction. Shading of the benthic environment is a long term impact associated with marinas. While there are presently no seagrasses in the project area, the 6 foot wide shelf which parallels the bulkhead is colonized by oyster assemblages and algae. Since the marginal dock will be placed 6 feet waterward of the seawall, sunlight will be permitted to reach the productive shelf which parallels the seawall. Additionally, since the marginal dock is 5 foot wide, the closest any boat will be to the seawall will be 11 feet. This will result in a buffer zone of 5 feet between the waterward extreme of the 6 foot shelf and any boat moored at the marina. Boats by their very existence and operation present potential negative short term and long term impacts to the environment. Potential damage from existing craft and those which occupy the marina to the seagrass beds in the extreme northwest portion of the lagoon will be eliminated or minimized by the planned installation of markers 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 lagoon as a "No Wake" zone. The fueling of boats, hull maintenance and sewage discharge are additional pollution sources associated with marinas. While the proposed marina will have no fueling or maintenance facilities, and while no liveaboards, boat cleaning, hull maintenance, nor fish cleaning 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 special conditions established by DER, the following special conditions are necessary: All craft docked at the marina shall be prohibited from pumping bilges and sewage into the waters of the lagoon. Ownership and use of the boat slips, or any of the marina facilities, shall be limited to those person(s) who own condominium unit(s) at the Surf Colony complex, to wit: Vanderbilt Surf Colony I, Vanderbilt Surf Colony II, Vanderbilt Surf Colony III, and, if and when constructed, Vanderbilt Surf Colony IV and V. Leasing or any other use of the boat slips, or the marina facility, by any person(s) other than the actual owner thereof shall be prohibited. Since the facility is small, and a full-time dock master is not proposed, limiting ownership and use of the boat slips to owners of condominium units at the Surf Colony complex will provide reasonable assurances that the conditions imposed on the requested permits will be complied with. Prohibiting the pumping of sewage and bilges will provide reasonable assurances that DER standards for bacteriological quality will not be violated. Protestors suggest that oils and greases, including lead found in marine fuels, could cause a degradation of water quality and affect the biota in the area. Protestors presented evidence through Dr. Nancy Nicholson, an expert in marine ecology and marine biology, that oils, greases, and lead could reasonably be expected to be ejected into the water column from boats occupying the marina, and that such pollutants, after entering the sediments, could be expected to enter the food chain. Protestors offered no evidence of the quantities of oil, greases or lead which could be expected to be injected into the water column, or to enter the food chain, other than "they are not large." Petitioner offered no evidence that the oils, greases or lead emitted by the boats occupying the marina would cause or contribute to a degradation of water quality below DER standards, or impact marine resources to such an extent as to be contrary to the public interest. Juxtaposed with the opinion of Protestors' expert is the empirical testimony of DER's witnesses, Terri Kranzer, an expert in water quality and aquatic biology, and Douglas Fry, an expert in dredge and fill impacts on water quality and aquatic biology, that the proposed facility and its operation will not cause or contribute to a degradation of water quality below DER standards and will not impact marine resources to such an extent as to be contrary to the public interest, so long as the Applicant complies with the permitting conditions. Protestors also suggest that turbidity, caused by boats operating from the marina, could cause a degradation of water quality and affect the biota in the area. Protestors' witness, Dr. Nicholson, testified to observing boats increase turbidity within the lagoon. She further performed a Secchi depth test, which measures the distance to which light will penetrate water, in the lagoon area. The background was measured at 42 inches. After the passage of a motorboat through the subject lagoon, the Secchi depth was reduced to 27 inches, and returned to the background level in 2-1/2 to 3 hours. Dr. Nicholson further testified that if the sediments "kicked up" were of an oxygen poor material, that they could scavenge dissolved oxygen from the waters. Protestors offered no evidence, however, which equated the Secchi depth test with the tests and standards established by DER for turbidity and transparency. There was no evidence, assuming turbidity did increase during boat activity, that DER standards for turbidity and transparency would be violated. Further, no evidence was introduced that such turbidity would cause or contribute to a degradation of the dissolved oxygen levels of the lagoon below DER standards. Contrary to the testimony of Dr. Nicholson, Protestors' other witness, William Doherty, a resident of the Surf Colony complex testified that he had operated his own 28 foot boat in the lagoon, and observed other boats operating in the lagoon, and never observed any increased turbidity. Terri Kranzer testified to the same effect. The depth within the lagoon is adequate for navigation, and there should be no increased turbidity caused by boats operating in the lagoon unless they venture into the shallow cove in the northwestern part of the lagoon. Designating the lagoon as a "No Wake" zone, and prohibiting navigation within the shallow cove, would provide reasonable assurances that there would be no increased turbidity associated with the proposed facility or its operation. Finally, Protestors suggest that if the proposed facility is permitted, DER's standard for Biological Integrity, Rule 17-3.111(4), F.A.C., will be violated. Dr. Nicholson conducted a sampling of benthic macroinvertebrates on the bulkhead of the lagoon and on the bulkhead of a nearby yacht basin, in order to calculate a Shannon-Weaver diversity index for both areas. The Shannon-Weaver index for the yacht basin reflected a level of benthic macroinvertebrates of less than 75 percent of that measured in the lagoon. The results of Dr. Nicholson's sampling are not, by her own admission, statistically significant. The lagoon and yacht basic are entirely dissimilar. The lagoon, with its diverse mangrove forests and large opening into Water Turkey Bay flushes well and is an area rich in biology. The yacht basin, on the other hand, is connected to Water Turkey Bay by a small channel and is completely bulkheaded. No valid comparison can be drawn between the lagoon and the yacht basin.
Findings Of Fact By application filed on September 9, 1980, Respondent/Applicant, John H. Land Builders, Inc., sought a permit from Respondent, Department of Environmental Regulation (DER), to conduct dredge and fill activities in an approximate one acre area located in the southeast corner of a proposed housing development in Section 10, Township 29 South, Range 19 East, in Hillsborough County, Florida. A copy of this permit application may be found as DER Composite Exhibit B. Specifically, Land sought to excavate 4,100 cubic yards of material (muck) and to backfill the area with 14,400 cubic yards of granular material from adjacent uplands to allow for development of a street and building lots in an unnamed wetland. A permit from DER is required because the project involves a wetland that is contiguous with a ditch that connects to the Palm River, all of which constitute waters of the State that are subject to dredge and fill permitting requirements. The plans have been reviewed by other state and local authorities in the Hillsborough County area, and no adverse comments have been received. After the installation is completed, the elevation of the land will be raised, and will permit five homesites to be built on the land as well as the construction of an access road to the property from an adjacent street. The installation in question is but a small part of a larger proposed housing development known as Timberlake Subdivision that will ultimately involve more than 300 homesites. However, no further dredge and fill activities under DER jurisdiction will be undertaken. The proposal of Respondent/Applicant was received by the Department and certain timely additional requests were made from the Department to the Applicant to provide information necessary to evaluate the request for permit. Applicant subsequently furnished the required information, and it may be found in DER Exhibit C. The Department performed a field inspection and review of the dredge and fill site, including the surrounding areas, to assess the impact of water quality caused by proposed dredging and filling activities in wetlands areas. It concluded that the Applicant had affirmatively provided reasonable assurance to the Department that the short-term and long-term effects of the activity would not result in violations of the water quality criteria, standards, requirements and provisions of Chapter 17-3, Florida Administrative Code. A copy of the permit application appraisal may be found in DER Exhibit A. On January 21, 1981, DER issued its Intent to Issue a dredge and fill/water quality certification with certain conditions therein, including the requirement that future development be dependent upon separate stormwater review by the Department (DER Exhibit D). On October 20, 1980, Applicant filed a Notice of Stormwater Discharge with the Department's Southwest District Office in Tampa (DER Composite Exhibits B & F). Thereafter, the Department conducted a field inspection and review of the proposed housing development and surrounding areas to determine whether the proposed stormwater discharge would have a significant impact on water quality. Based upon the results of that inspection, which concluded that the proposed discharge would not have a significant impact on the waters of this State, the Department issued Applicant a stormwater exemption on November 7, 1980. The project site is located in an unnamed wetlands area. It is weedy and has a dense cover of primrose willow (Ludwigia peruviana), willow (Salix caroliniana), cattail (Typha sp.), red maple (Ace rubrum) and is overgrown with grapes vines (Vitus rotendifolia). It lies just to the north of a series of fish farms owned by Petitioner, Penisular Fisheries, Inc. Other commercial industries and single family dwellings are found south of the proposed activities. To the west and northwest lie marshlands, two old borrow pits, and Interstate Highway 4. Water runoff from the dredge and fill area will flow to the storm drainage system in the proposed street, and from there to a designated retention pond. Because there will be minor contaminants in the runoff, the water will be retained for treatment for a period of five days, which exceeds the 100 hour retention period required by DER. After treatment, the runoff will flow into a well-defined county drainage ditch west of 58th Street, travel down the ditch which lies adjacent to the fish ponds, and then meander into the existing marshland. Water runoff from the remainder of the project (excluding the dredge and fill area) will drain into the two existing borrow pit lakes which lie close to Interstate Highway 4. The designated retention pond will be located west of the project and has a controlled spill-off elevation. It will provide sufficient treatment to and cleaning of the water to insure that no violation of water quality standards will occur. A stormwater system to be constructed by Applicant will actually reduce the volume of water runoff now occurring. Reasonable assurances have been given that the short-term and long-term effects of the proposed activity will not result in violations of the water quality criteria, standards, requirements and provisions of the Florida Administrative Code. Based upon Use location of the point of discharge of Land's proposed stormwater discharge, the volume and frequency of discharge for which the proposed facilities are designed, and the anticipated constituents of discharge, the proposal will not have a significant impact on the water quality of the waters of this State. Accordingly, the exemption from stormwater licensing requirements was properly issued by the Department. Water quality violations which were alleged to have existed in a ditch on property adjoining the properties of Land and Petitioners were the subject of a notice of violation issued to the owners of that property. However, no notice of violation was ever issued to Land. Further, the ditch is not a part of the installation proposed by Applicant for issuance of the dredge and fill permit. Petitioners' concern is that Applicant has not given reasonable assurance that water quality standards would not be violated by the stormwater discharge and that downstream waters might be contaminated by urban runoff from the project. In reaching that conclusion, Petitioners' expert relied on a review of certain materials submitted to him by Petitioner's counsel. He did not visit the project site, nor had he reviewed drainage plans or construction drawings for drainage improvements contemplated by the notice of stormwater discharge filed by Land.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that Respondent Department of Environmental Regulation grant the requested dredge and fill permit/water quality certification to Respondent/Applicant John H. Land Builders, Inc. It is further RECOMMENDED that the Respondent Department of Environmental Regulation enter a final order confirming the stormwater exemption issued by the Department to Respondent/Applicant on November 7, 1980. DONE and ENTERED this 27th day of April, 1981, in Tallahassee, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 27th day of April, 1981.
Findings Of Fact By Joint Application for Works in the Waters of Florida filed April 14, 1993, Petitioner requested a dredge and fill permit. The application pertains to the construction of a 3245 square feet platform over a part of Doctors Bay in Naples. Petitioner intends to construct a home on the platform. The application explains that an existing dock covers 1200 square feet of the area proposed to be covered by the new structure. Petitioner offers in the application to enhance the habitat beneath the overwater structure by adding clean concrete rubble and pilings. The application assures that the material would provide suitable substrate and increase the surface area for encrusting organisms such as algae, barnacles, sea squirts, and oysters. The application states that Petitioner would riprap the shoreline and a deadend corner immediately west of the parcel in order to improve tidal flushing. According to the application, Petitioner would also plant mangroves near the deadend corner, as well as inside an atrium entrance to the home. The proposed structure would be located at the south end of a parking lot at the southeast corner of Park Shore Drive and Gulfshore Boulevard. West of the proposed structure is a narrow strip of land running alongside Gulfshore Boulevard. North of the proposed structure is a part of the narrow strip of land and the parking lot. The north and west sides of the proposed site are bulkheaded by vertical seawalls. The waters of Doctors Bay extend south and east of the proposed structure. To the south are a 10-slip dock and a fingerfill peninsula. To the east are several overwater structures covering about 25,000 square feet of water with each structure measuring about 50 feet by 500 feet. The structures are devoted to retail operations. The structure immediately east of the proposed structure is a restaurant owned by Petitioner. Doctors Bay is a Class II waterbody, although it is closed to shellfishing. The waterbody was originally a viable estuary, as part of a relatively shallow back bay and mangrove system. But, as a result of extensive development permitted mostly in the 1960s and 1970s, the waterbody bears little resemblance to the natural system that it once was. Vast areas of the estuary have been dredged and filled for the construction of structures and bridges. Tidal flushing has been impeded by the fill, as well as the uneven bottom left by the dredging projects. Tidal flushing in the area of the proposed project is impeded by the Park Shore Drive bridge to the north. The bay is nearly closed at the point of the bridge. The flushing problem is exacerbated at the proposed site due to prevailing currents and winds, which drive vegetative debris and trash into 90- degree corner of the bay at the site of the proposed structure. The water in this artificially created deadend corner of the bay is not without a source of agitation, however. In addition to runoff from the nearby parking lot, undetained stormwater from Gulfshore Boulevard is dumped into the deadend corner by a stormwater outfall. Not surprisingly, the waters of Doctors Bay violate water quality standards for dissolved oxygen (DO). Monthly DO readings from 1977 through 1989, which was the last year such date were collected, show a trend of water quality deterioration. The site closest to the proposed site violated the DO standard of four parts per million one month each year between 1977 and 1987. In 1988, the same waters violated the DO standard four months, and, in 1989, these waters violated the DO standard eight months. Almost all of the Moorings Bay system, of which Doctor Bay is a part, violated the DO standards for over six months of 1989. Sediments at the proposed site are sandy and silty with shell fragments and high concentrates of polychaetes, or marine worms. Open-water sediments are oxygenated with no presence of hydrogen sulfide. Sediments under existing platforms are not oxygenated and convey the rotten-egg odor of hydrogen sulfide. Microalgae exist on the open-water sediments and shell fragments, but not on those under the platforms. Transparency is much greater in the open water than in the shaded water. Pilings in the area hosted the typical encrusting organisms, such as oysters, barnacles, and periwinkles. As stated in Respondent's inspection report of July 7, 1993, a short- term impact of the proposed project would be the resuspension of nearby sediments from the turbulence of the pile-driving. Under the circumstances, it is unnecessary to address the other short-term concern expressed in the inspection report-the resuspension of heavy metals suspected to exist in the sediments due to the stormwater outfall. As stated in the inspection report, other impacts of the proposed project would include a reduction in transparency. Shading reduces the depth at which photosynthesis takes place, By reducing transparency, the proposed project would likely reduce by at least 10 percent the compensation point, which is the point at which the production of oxygen by plants through photosynthesis is equal to the use of oxygen by plants through respiration by organisms. Also, the proposed structure would interfere with what little water movement exists in the area. Pilings would trap debris, whose decomposition in the water would further reduce DO levels. By letter July 12, 1993, Respondent required Petitioner to submit, among other things, reasonable assurance that the proposed mitigation would reduce the expected impacts of the proposed project and a plan or procedure to protect nearby waters. Petitioner proposes mitigation through the placement of riprap under the proposed structure, which is intended in part to ensure that trapped debris and trash remain above-water. Petitioner also proposes the planting of mangroves over a 140 square foot area, despite the presence of the seawall, and a 400 square foot area atrium in the structure. Aside from an upland relocation of the proposed project, no mitigation can provide the necessary reasonable assurances. Correctly concluding the same thing, Respondent informed Petitioner, by letter dated March 14, 1994, that his application was denied.
Recommendation Based on the foregoing, it is hereby RECOMMENDED that the Department of Environmental Protection enter a final order denying Petitioner's application.

The Issue The issues in this case are whether the Department of Environmental Protection (DEP) should modify the conditions of permits held by the Deep Lagoon Boat Club, Ltd., d/b/a Deep Lagoon Marina (Applicant), to allow Applicant to construct and operate a boat travel lift in a new location at the marina and to substitute a 60-foot wide flushing channel required by the prior permits with two-48 inches box culverts.
Findings Of Fact Applicant owns and operates Deep Lagoon Marina (the Marina). The Marina comprises uplands and three canals adjoining MacGregor Boulevard south of downtown Fort Myers. The Marina presently consists of 61 wet slips, 200 dry slips, and other marina-related buildings. The Marina is on Deep Lagoon, a Class III surface water body less than one-half mile from the Caloosahatchee River. Deep Lagoon is a short, largely mangrove- lined waterway that runs north into the Caloosahatchee River. The Caloosahatchee River runs west from Lake Okeechobee past Fort Myers to the Gulf of Mexico. One of Applicant's predecessors in interest dredged the three canals in the 1950s or 1960s, and a marina has existed at this location since that time. As a result of a purchase in 1997, Applicant owns at least the uplands and claims ownership of the submerged bottoms of the canals. The parties have stipulated that ownership of the submerged bottoms of the canals is not being litigated or decided in this proceeding and that, subject to the issue's being decided adverse to the Applicant in other proceedings, sufficient ownership is presumed for purposes of this proceeding. From north to south, the Marina comprises the north canal, which is about 1200 feet long and bounded on the north by a red mangrove fringe 10-20 feet wide; a peninsula; the central canal, which is also known as the central or main basin and is roughly the same length as the north canal; a shorter peninsula; and the south canal, which is about half the length of the central canal and turns to the southeast at a 45-degree angle from the midway point of the central canal. The three canals are dead-end canals, terminating at their eastern ends a short distance from MacGregor Boulevard. Petitioner, Brenda Sheridan, resides at 842 Cal Cove Drive, Fort Myers, Florida, which is on the shores of the Caloosahatchee River at Deep Lagoon, just across the south canal from the Marina. Intervenor, Save the Manatee Club (STMC), is a non- profit Florida corporation with approximately 40,000 members. The organization's stated purpose includes protecting the manatee and its habitat through public awareness efforts, research support and advocacy, which activities benefit manatees, STMC, and its members. The Florida Legislature has recognized STMC's substantial interest in manatee protection by designating it a member of the manatee protection committee provided by the Florida Manatee Sanctuary Act at paragraph 370.12(2)(p), Florida Statutes, and by requiring the state to solicit recommendations from STMC regarding the use of Save the Manatee Trust Fund monies, at Section 370.12(5)(a), Florida Statutes. Numerous members of STMC reside within Lee County, where they observe, study, photograph, and actively attempt to protect manatees from collisions with watercraft. These efforts benefit manatees and provide STMC's members with educational and recreational benefits in the waters of Lee County that would be affected by the proposed activity. STMC has expended substantial resources in advocating increased legal protection of manatees in Lee County, including additional boat speed regulations on the Caloosahatchee River. STMC has also constributed funds for the rescue and rehabilitation of manatees exposed to red tide in Lee County waters. Injury, mortality, and loss of important habitat would produce significant, adverse impacts to the manatee, thereby diminishing the ability of STMC's members to observe, study, and enjoy manatees in waters that would be affected by the proposed activity and frustrating STMC's efforts to preserve and protect manatees in Lee County. Permit History On December 9, 1986,, Applicant's predecessor in title applied to DEP's predecessor agency, the Department of Environmental Regulation (DER), for a dredge and fill permit to rehabilitate the 61 existing wet slips at the Marina and add 113 new wet slips. Because Deep Lagoon violated Class III water quality standards, and there was concern for the West Indian manatee, a listed endangered species which uses the waters in and around Deep Lagoon, DER placed conditions on the permit and gave notice of intent to grant the permit, with conditions, on July 26, 1988. Petitioner and others challenged the issuance of the permit, and formal administrative proceedings were conducted, culminating in a final order on August 24, 1989, approving the permit, with additional conditions, and certifying under the federal Clean Water Act that state water quality standards were met because there would be a net improvement in water quality of the poorly-flushed canals. Sheridan, et al. v. Deep Lagoon Marina and Dept. of Environmental Reg., 11 F.A.L.R. 4710 (DER 1989). Wetland Resource Permit 361279929, incorporating all of the conditions, was issued on September 22, 1989, for construction and operation of the project for five years (the 1989 Permit). Petitioner and the others appealed the final order. In Sheridan v. Deep Lagoon Marina, 576 So. 2d 771, 772 (Fla. 1st DCA 1991), the court, relying on the 1987 water quality data, noted the "very poor water quality" of Deep Lagoon, as reflected in part by the presence of oil and grease 20 times the Class III standard, copper 13 times the standard, lead 20 times the standard, mercury 1000 times the standard, and coliform bacteria "too numerous to count." However, the court affirmed the issuance of the 1989 Permit under the statutory authorization of a permit where ambient water quality does not meet applicable standards, but the activity will provide a net improvement to the waters. On the certification issue, though, the court reversed and remanded. The court held that the hearing officer erroneously excluded evidence on DER's certification of the activity as in compliance the federal Clean Water Act. Following proceedings on remand, DER entered Final Order on Remand on April 10, 1992, which revoked the earlier certification of compliance and, citing 33 United States Code Section 1341, as authority, waived certification as a precondition to federal permitting. Sheridan, et al. v. Deep Lagoon Marina and Dept. of Environmental Reg., 14 F.A.L.R. 2187 (DER 1992). The 1989 Permit expired on September 22, 1994, but Environmental Resource Permit 362504599 was issued on October 9, 1995, essentially extending the 1989 Permit conditions for ten years, to October 9, 2005. Minor modifications were approved on November 17, 1995, March 26, 1997, and April 15, 1997. Environmental Resource Permit 362504599, with all conditions and subsequent modifications, is referred to as the 1995 Permit. Permit Conditions In general, the 1995 Permit authorizes the owner of the Marina: to renovate and expand an existing marina from 61 wet slips to 174 wet slips by: excavating 0.358 ac of uplands to create a flushing canal, installing 375 linear feet of seawall along the sides of the flushing canal, excavating 2.43 ac of submerged bottom to remove contaminated sediments, backfilling 2.41 acres of the dredged area (the main basin and south canal to -7 ft. MLW and the north canal to -6 ft. MLW) with clean sand, renovating the existing 61 slips, and constructing an additional 14,440 square feet of overwater decking for 113 new slips, providing after-the-fact authorization for construction of 2 finger piers, creating a 400 sq. ft. mangrove fringe, constructing 180 linear feet of seawall in the vicinity of the mangrove fringe, and relocating and upgrading fueling facilities. The 1995 Permit authorized activities to proceed in three phases: First, the majority of the water quality improvement measures will be implemented as required in Specific Condition 5. Second, the over water docking structures will be constructed and the fueling facilities will be upgraded and relocated as required in Specific Conditions 6 and 7. Third, the new slips will be occupied in accordance with the phasing plan in Specific Condition 9. Specific Condition 5 imposed several requirements designed "to ensure a net improvement in water quality." Among them, Specific Condition 5 stated in pertinent part: In order to ensure a net improvement to water quality within the basin, the construction of any new docking structures or installation of any new pilings shall not occur until the below-listed conditions (A-K) have been met. . . . A baseline water quality study . . .. A stormwater treatment system providing treatment meeting the specifications of Florida Administrative Code 40E-4 for all discharges into the basins from the project site shall be constructed. . . . The boat wash area shall be re-designed and constructed as shown on Sheets 23 and 23A. All water in the washdown area shall drain into the catch basin of the wastewater treatment system shown on Sheet 23. The water passing through the wastewater treatment system shall drain to the stormwater management system which was previously approved by the South Florida Water Management District. The filters of the wastewater treatment system shall be maintained in functional condition. Material cleaned from the filter shall be disposed of in receptacles maintained specifically for that purpose and taken to a sanitary landfill. This system shall be maintained in functional condition for the life of the facility. Contaminated sediments shall be dredged from the areas shown on Sheets 5 and 7 of 23. A closed-bucket clam shell dredge shall be used. The north canal shall be dredged to at least -9.9 feet MLW and backfilled with clean sand to -6 feet MLW. The [main] basin shall be dredged to at least -7.3 feet MLW and backfilled with clean sand to -7 feet MLW. The south canal shall be dredged to at least -10.5 feet MLW and backfilled with clean sand to at least -7.0 feet MLW. Backfilling shall be completed within 120 days of completion of dredging. . . . The sediments shall be placed directly in sealed trucks, and removed to a self-contained upland disposal site which does not have a point of discharge to waters of the state. A channel, 260 ft. long, 60 ft. wide, with a bottom elevation of -4.5 ft. MLW shall be excavated between the north canal and the main basin to improve flushing. * * * K. Upon completion [of] conditions A-J above, renovation of the existing 61 wet slips and construction of the 113 additional wet slips may proceed with the understanding that construction of all 113 additional slips is at the risk of the permittee and that if the success criteria in the monitoring and occupancy program are not met, removal of all or part of the additional slips may be required by the Department. Specific Condition 8 addressed the phasing of occupancy of the wet slips. Specific Condition 8 provided in pertinent part: Occupancy of the additional 113 wet slips shall occur in two phases, described below. Permanent occupancy of the slips shall require [DEP] approval, contingent upon the water quality monitoring program demonstrating a statistically significant (Specific Condition 9) net improvement for those parameters which did not meet State Water Quality Standards in the baseline study. The permittee agrees that if [DEP] determines that net improvement has not occurred, or if violations of other standards occur, and if the corrective measures described in Specific Condition 10 are not successful, all of the additional slips occupied at that time shall be removed. . . . Phase I--Upon completion of the baseline water quality study and the work specified in Specific Condition No. 5, the existing 61 slips and an additional 56 slips, totalling 117 slips, may be occupied. . . . If at the end of one year of monitoring, the data generated from the water quality monitoring program shows a statistically significant improvement over baseline conditions, for those parameters in violation of State Water Quality Standards, and no violations of additional parameters, . . . the new 56 slips which were occupied shall be considered permanent. Phase II--Upon written notification from [DEP] that Phase I was successful, the remaining 57 additional slips may be occupied. Water and sediment quality monitoring shall continue for two years after the occupancy of 140 of the 174 slips. If a statistically significant net improvement to water quality over baseline conditions for those parameters in violation of State Water Quality Standards [sic] and no violation of additional parameters is shown by the monitoring data, and confirmed by [DEP] in writing, the additional slips shall be considered permanent. Specific Condition 11 added: Implementation of the slip phasing plan described in Specific Condition 8 shall be contingent on compliance of boaters with existing speed zones in the Caloosahatchee River and trends in manatee and [sic] mortality. . . . Approval of additional slips will depend upon manatee mortality trends and boater compliance with speed zones in the Caloosahatchee River and additional slips may not be recommended. . . . Based on the results of the evaluations of Phases I and II, [DEP] may require that slips be removed to adequately protect manatees. Specific Condition 12 required the construction of a 400 square-foot intertidal area for the planting of mangroves to replace the mangroves lost in the construction of the flushing channel. Specific Condition 14 prohibited live-aboards at the marina. Specific Condition 15 added various manatee-protection provisions. Applicant's DOAH Case Nos. 98-3901 and 98-5409 Seeking to satisfy certain of the requirements of Specific Condition 5 of the 1995 Permit, Applicant filed with DEP, on December 10, 1997, an application for an Environmental Resource Permit (ERP) and water quality certification to construct a surface water management system to serve 15.4 acres of its 24-acre marina. On March 3, 1998, Applicant's engineering consultant submitted drawings to DEP with notification that Applicant intended to "maintenance dredge the internal canals of Deep Lagoon Marina," in conformity with Rule 62-312.050(e), Florida Administrative Code. The letter described the proposed dredging as mechanical "with no discharge back into Waters of the State." The letter assured that Applicant's contractor would use turbidity curtains "around the dredging and spoil unloading operation" and advised that the contractor would unload the spoil "to the north peninsula upland area." The letter stated that the dredging would "be to the design depth/existing canal center line depth of -7 NGVD," which was established by the 1995 Permit, and would be "done in conjunction with the required dredging under [1995 Permit] Condition 5(D)." The consultant attached to the March 3 letter several drawings showing the dredging of all three canals. For each canal, the drawings divided the dredging into two areas. (For 1.82 acres, the contractor would dredge contaminated materials from the dead-ends of the three canals and then replace these materials with clean backfill material, as already authorized in the 1995 Permit.) For 4.84 acres, which ran through the remainder of the three canals, the contractor would maintenance dredge in accordance with the cross-sections provided with the letter. By letter dated March 13, 1998, DEP stated its determination that, pursuant to Rule 40E-4.051(2)(a), Florida Administrative Code, the proposed activity was exempt from the requirement to obtain an ERP. The letter warned that, pursuant to Chapter 62-302, Florida Administrative Code, the construction and operation of the project must not cause water quality violations. The letter added that DEP could revoke its determination of exemption if the "basis for the exemption is determined to be materially incorrect, or if the installation results in water quality violations." The letter provided a point of entry for persons whose substantial interests are affected by DEP's determination. Petitioner challenged the exempt status of the maintenance dredging, and STMC intervened in support of the challenge, which was referred to DOAH and given DOAH Case No. 98-3901. But Applicant's contractor proceeded during the pendency of the challenges and completed the maintenance dredging in the three canals. (Applicant's contractor also performed the contaminant dredging and clean backfilling authorized by the 1995 Permit.) On November 5, 1998, DEP gave notice of intent to issue the ERP for the surface water management system and certify compliance with state water quality standards, pursuant to Section 401 of the Clean Water Act, 33 United States Code, Section 1341. Petitioner filed a challenge on December 8, 1998, and the matter was referred to DOAH, where it was given DOAH Case No. 98-5409. On February 6, 1999, DEP revised the notice of intent by withdrawing its certification of state water quality compliance. As it did with the 1989 Permit, DEP again waived state water quality certification, consistent with a letter dated February 2, 1998, in which then-DEP Secretary Virginia Wetherell announced that DEP would waive state water quality certification for all activities in which the agency issues an ERP based on the "net improvement" provisions of Section 373.414(1)(b), Florida Statutes. DOAH Case Nos. 98-3901 and 98-5409 were pending when Applicant sought the modifications to the conditions of the 1995 Permit which are the subject of this case (DOAH Case No. 99- 2234). DOAH Case Nos. 98-3901 and 98-5409 were consolidated and heard by Administrative Law Judge (ALJ) Robert E. Meale on February 11 and May 3-4, 1999. On November 24, 1999, ALJ Meale entered a Recommended Order recommending a final order revoking DEP's determination of an exemption for maintenance dredging in DOAH Case No. 98-3901 and denying the ERP in DOAH Case No. 98- 5409. The recommendation to deny the ERP in DOAH Case No. 98- 5409 was based on findings and conclusions: (1) that Applicant had not provided reasonable assurances that the construction and operation of the proposed surface water management system would result in a "net improvement" in water quality; and (2) that the direct and secondary impacts of the construction and operation of the system would adversely affect the West Indian manatee. Water Quality As indicated in relating the permitting history of this site, water quality in the waters of the Marina has been poor. See Findings 10 and 12, supra. ALJ Meale recently found in his Recommended Order on Case Nos. 98-3901 and 98-5409 as follows: The Caloosahatchee River is laden with sediments, partly due to intermittent discharges from Lake Okeechobee. Seagrass in the riverbottom cannot grow in water much deeper than four feet. Some seagrass grows at the mouth of Deep Lagoon, but little seagrass extends into the lagoon itself. The water quality in the canals is very poor for dissolved oxygen and copper. Applicant stipulated that the water quality in Deep Lagoon violates state standards for dissolved oxygen, copper, and coliform bacteria. In 1997, the canals violated water quality standards for dissolved oxygen nearly each time sampled during the wet season and one-third of the times sampled during the dry season. The dissolved oxygen levels violated even the lower standards for Class IV agricultural waters two-thirds of the times sampled during the wet season. In 1997, the canals violated water quality standards for copper in the water column each time sampled during the wet season and two-thirds of the times sampled during the dry season. During three of the dry season samplings, copper levels were 20 to 30 times lawful limits. The three lowest wet season copper levels were double lawful limits. Copper is a heavy metal that is toxic to a wide range of marine organisms. Copper is applied to boat hulls to prevent marine life from attaching to the hulls. In 1997, the canals violated water quality standards for total coliform bacteria (for any single reading) three of the 60 times sampled during the dry season and one of the 56 times sampled during the wet season. The canals violated the more relaxed, 20-percent standard (which is violated only if 20 percent of the readings exceed it) during the wet season, but not during the dry season. In 1997, the canals violated water quality standards for lead in the water column in one sample (by 25 percent) out of 36, but did not violate water quality standards for oil and grease or fecal coliform bacteria. Results of testing for mercury in the water column (as opposed to sediments) are not contained in the record. As compared to 1987, the water quality in the canals has improved in all but one important respect. In 1987, the water column readings for copper were five to six times higher than the highest 1997 reading. In 1987, the total coliform bacteria were too numerous to count because the colonies had grown together in the sample. However, comparing the April 1987 data with the May 1997 data for the same approximate times of day and the same locations, the dissolved oxygen levels in the three canals have declined dramatically in the last 10 years. Ten years ago, in a one- day sampling period, there were no reported violations; ten years later, in a one-day sampling period, there were four violations. Even worse, the amount of dissolved oxygen in the water during daylight hours has been halved in the last 10 years with a smaller decrease during nighttime hours. In this case, the parties stipulated that the waters of Deep Lagoon and the Marina are Class III marine waters that do not meet Florida water quality standards for dissolved oxygen, copper, and total coliform bacteria. They also stipulated that there were violations in 1987 for oil and greases (20 times standard), fecal coliform (too numerous to count), lead (20 times standard), cadmium (ten times standard), mercury (1,000 times standard), biological diversity, and tributytin (150 times standard) (although DEP and Applicant do not think the 1987 data are relevant). Data collected in 1987 showed average flushing time in the north canal to be 183 hours (tidal prism method), 90.5 hours (current velocity), and 50 hours (dye concentration reduction method). Data collected in 1987 showed average flushing time in the main basin to be 208 hours (tidal prism method), 48 hours (current velocity), and 154 hours (dye concentration reduction method). Manatees The parties stipulated that Lee County is a heavy use area for the West Indian Manatee and that manatees use the water south of Deep Lagoon and the Caloosahatchee River on a year-round basis. ALJ Meale recently found in his Recommended Order on Case Nos. 98-3901 and 98-5409 as follows: The Caloosahatchee River is critical habitat for the endangered West Indian manatee. Up to 500 manatees use the river during the winter. When, during the winter, the water cools, the animals congregate in waters warmed by the thermal discharge from a power plant about 13 miles upstream of Deep Lagoon. When, during the winter, the water warms, the manatees swim downstream, past and into Deep Lagoon searching for food. Manatees frequently visit Deep Lagoon. It is one of the few places between the power plant and the Gulf where manatees can find a quiet place, relatively free of human disturbance, to rest and feed. Within Deep Lagoon, the Iona Drainage District ditch runs parallel to the north canal, separated from the canal by the previously described mangrove fringe. The Iona Drainage District ditch empties into Deep Lagoon just north of the mouth of the north canal. Manatees frequently visit the ditch because it is a seasonal source of freshwater, which the manatees drink. Manatees visit the north canal due to its moderate depths and proximity to the freshwater outfalls of the Iona Drainage District ditch. Manatee mortality from watercraft is extremely high in the immediate vicinity of Deep Lagoon, and the mortality rate has increased in recent years. The rate of manatee deaths from collisions with watercraft has increased with the popularity of motorboating. Boat registrations in Lee County rose from 13,000 in 1974 to 36,000 in 1997. The potential for mitigation offered by the enactment of speed zones has been undermined by the fact that nearly half of the boaters fail to comply with the speed limits. It is clear that manatees frequent Deep Lagoon near the mouth of the north canal. There are seagrass beds there to serve as a food source, and freshwater from the Iona Drainage District ditch discharges in that area. The evidence in this case includes testimony and numerous photographs of manatees not only in that vicinity but up to 200 feet into the north canal. While there are no seagrass beds in the north canal itself, freshwater from the Iona Drainage District ditch discharges into the north canal all along the length of mangrove fringe on the north shore of the canal. It is not clear how much further up the north canal manatees go, but they probably frequently continue further into the north canal since one primary attraction of the north canal for manatees at this time is its relative quiet and peacefulness. Manatees also make some use of the central and south canals of the Marina, but they seem to prefer the north canal for its peacefulness and for the fresh water supply from the Iona Drainage District ditch. The Florida Department of Transportation recently has constructed a retention pond for MacGregor Boulevard in the vicinity of the Marina which will discharge fresh water into the main basin of the central canal. This may make the central canal more attractive to manatees than it is at this time, notwithstanding the relatively high level of boating-related activity there. New Boat Travel Lift The Marina's existing boat travel lift is located in the main basin of the central canal. There also are the remnants of an older travel lift operation at the western end of the central peninsula extending into Deep Lagoon. Applicant proposes to construct and use a new boat travel lift at the eastern terminus of the north canal. The proposed location of the new travel lift will be closer to the approved location of a new service center building. A travel lift essentially consists of a heavy-duty, U-shaped frame which is built on wheels and motorized for mobility. Heavy-duty straps are suspended from the frame using pulley systems. The travel lift is driven out over water on specially-built tracks so the straps can be placed underneath large vessels (over 40 feet) and tightened using the pulleys to secure the vessels; the travel lift is then driven off the tracks, and the vessels are transported to a dry storage or repair location, where the vessels are lowered, and the straps are removed. The process essentially is reversed to return vessels to the water. The direct impact of construction of the new boat travel lift involves removal of some mangroves existing at the terminus of the north canal and sinking pilings to support the tracks extending into the water on which the travel lift operates. Applicant proposes to mitigate the mangrove impacts by filling areas on either side of the proposed travel lift to just above the mean-high waterline and planting the areas with mangroves. Not only will this be a net increase the amount of mangrove fringe, the decrease in water depth at the east end of the north canal also will improve flushing of the canal to some extent. Applicant also proposes to remove exotic plants all along the shoreline of the Marina's canals for the life of the Marina. It is the Marina's intent to use the travel lift only for vessels too large to be lifted by forklifts operated at the main basin of the central canal. The Marina is purchasing new, larger (37,000 pound) forklifts (compared to the 10,000 pound forklifts currently in use), which can lift vessels up to approximately 42 feet long. Use of the larger forklifts will reduce the use of the travel lift. At this time, there is no proposed specific condition to limit use to the travel lift to vessels too large to be lifted by the new forklifts. New Specific Condition 33 in the proposed permit modifications provides: "Launching of vessels from the dry storage facilities shall be prohibited in the north canal at the site." New Specific Condition 34 in the proposed permit modifications provides in part: "Launching and retrieval of vessels in the north canal shall be restricted to vessels stored/moored at the marina facility that require boat repair." New Specific Condition 34 also would require Applicant to maintain logs for the travel lift and boat repairs to allow DEP to verify compliance by comparing the two logs. There was some disagreement as to the intent of the quoted proposed new specific conditions. A DEP witness thought it meant that the Marina only could use the travel lift for repair of vessels permanently moored at the Marina, but the Marina's representative did not think the language would prohibit the repair of other vessels as well. Assuming that vessels not permanently moored at the Marina will be accepted for repairs, and that only vessels too large for the new forklifts will use the new travel lift, it can be anticipated that an average of 6-10 vessels a week will use the travel lift for retrieval from the water and discharge back to the water. To some extent, use of the travel lift is limited by the average time it takes to use the lift. But considering only those limitations, it is possible use the lift as many as 19 times in a day in an emergency--e.g., when a hurricane is approaching, and the Marina is trying to get as many boats out of the water as possible. On average, use of the travel lift also will be limited by market conditions and the capacity of the new service center to store and repair large vessels. More than half of the average use of 6-10 vessels a week probably will occur on Fridays (for repairs before peak weekend boating) and Mondays (for repairs after the weekend peak). At this time, there is no proposed specific condition to limit use of the new travel lift. But at final hearing, the Marina expressed its willingness to accept a limit of an average of ten vessels a week. (Counting retrieval from the water and discharge back to the water for each vessel, the agreed limit would be an average of 20 uses of the travel lift a week). The Marina was not willing to accept a daily limit. Secondary impacts from such a limited use of the proposed new travel lift on water quality and manatees are difficult to assess precisely. The travel lift itself uses some form of lubrication, but only the straps enter the water during operation. Historically, vessels have been pressure-washed and had their bilges and engines flushed while on the existing travel lift in the main basin of the central canal at the Marina, and wash-water from these operations has entered the main basin at that location. Wash-water from such operations at the proposed new travel lift location would enter the north canal, subject to the construction and operation of an adequate surface water management system, as required by Specific Condition 5.C. of the 1995 Permit. Cf. DOAH Case No. 98-5409, supra. It is possible that vessels in need of repair entering the north canal and proceeding to the proposed new travel lift location (whether under power or being towed) could leak oil or gasoline. Both contaminants would rise to the surface. Leaked gasoline and the more volatile components of oil could be expected to evaporate relatively quickly; the residue of oil contamination would be persistent. Such spills would affect water quality and could affect manatees drinking fresher water from the surface of the north canal. There was no evidence from which to predict or quantify such impacts. It would be possible for manatees to be injured by vessels using the proposed new travel lift. Although such vessels would be traveling at low speed (1-2 mile per hour), maneuvering such large vessels in close quarters like the north canal sometimes is accomplished by intermittent bursts of high engine and propeller speeds, both in forward and reverse gears. Such operations could cause a vessel to lurch in the direction of a manatee; if done in reverse gear, a manatee could be sucked into the speeding propellers. It also is possible for a manatee to be crushed against the bottom or against a structure of the Marina facility during such operations. Despite the possibility of injury to manatees from use of the new proposed travel lift, it is clear that most manatee injuries and deaths from boat collisions occur as a result of propeller injuries from boats being operated at high-speed. Manatees are known to frequent and safely use marinas where large vessels operate at low speed. The risk of danger to manatees from use of the proposed new travel lift can be characterized as being minimal if not speculative, especially in view of the manatee protections in Specific Condition 15 of the 1995 Permit. Initially, DEP misunderstood the nature of the proposed new travel lift, thinking it would greatly increase boat traffic in the north canal. When the minor impact of the project was explained, DEP's concerns were allayed. Greater risk of danger to manatees would occur from the addition of wet slips in the north canal, but those impacts are not secondary to the travel lift proposal; they are completely separate impacts that are governed by the pre-existing 1995 Permit. Petitioner and Intervenor were critical of the absence of a specific condition for the daily logs to be presented to DEP for inspection on a regular basis. See Finding 42, supra. They contended that absence of such a requirement would compromise compliance enforcement. But DEP inspection of the logs at times of its own choosing could be just as effective. The key to enforcement is having an enforceable specific condition limiting use of the travel lift. Petitioner and Intervenor also were critical of using a simple weekly average to limit use of the new travel lift. They correctly argue that the time over which the weekly average would be computed must be designated for such a use limitation to be enforceable. They also contend that there should be a daily limit. Assuming a weekly average limitation of ten, a daily limit of ten would not be unreasonable if it allowed leeway to exceed the daily limit in cases of emergencies such as approaching hurricanes. Replacing Flushing Channel with Culverts Applicant's proposal to replace the 60 foot by 4.5 foot-deep flushing channel with two 48-inch culverts is motivated by practical considerations. Applicant essentially wishes to avoid the expense of constructing the channel required under the 1995 Permit and having to bridge the channel to make use of the peninsula between the central and north canals. Part of the Marina's initial motivation for the channel was to expand operations and allow access to the north canal from the main basin. Part of the channel was to have been used by the Marina as a new forklift area with access to boat storage areas on both sides of the channel. In the 1989 Permit, it was stated that the channel was "to act as a sediment sump." It was not until the 1995 Permit that the channel was said to serve to "improve flushing." Most of the "net improvement" of water quality at the Marina was to come from proposed contamination dredging of the canals (and backfilling with clean sand), removal of contaminated soil from Marina uplands, installation of a redesigned boat-wash area, and installation of an adequate surface water management system. Most flushing benefits were anticipated to come from making the canals shallower by back-filling after dredging. Flushing from the channel was presented as "frosting" on the "net improvement cake." The hydrographic evidence was that the channel, in conjunction with back-filling the Marina's canals, would indeed increase flushing of the Marina's canals to some extent. Looking at the main basin only, the channel would improve flushing by up to 27 percent. But looking at the Marina's canals overall, the channel would only increase flushing by up to 0.6 percent. By comparison, the hydrographic evidence was that the proposed flushing culverts also would contribute to increased flushing but by a smaller amount. Looking at the main basin only, the proposed flushing culverts would improve flushing by up to 4 percent. Looking at the Marina's canals overall, the proposed flushing canal would only increase flushing by up to 0.2 percent. Petitioner and Intervenor question the reliability of Applicant's calculations of flushing times without more up-to- date data on the depths of the canals after contamination and maintenance dredging. But the evidence was that differences in the starting depths would not have a significant effect on the relative changes in flushing times from the channel versus the culverts; the differences would be approximately proportional regardless of the starting depths. In addition, the depths assumed in Applicant's calculations are based on the 1987 data and the requirements of the 1995 Permit. Compliance with the requirements of maintenance dredging and the 1995 Permit can be enforced, if necessary, in other proceedings. See, e.g., DOAH Case No. 98-3901, as to maintenance dredging. Applicant's calculations on flushing times do not account for the possibility of an additional benefit from the proposed flushing culverts. Applicant proposes to locate the culvert inverts at a depth of 6 feet. If a greater salinity gradient exists at that depth, the culverts would have a relative advantage over a 4.5 foot-deep channel in terms of flushing and the exchange of more oxygenated water between the north canal and the main basin. The existence of such a salinity gradient is suggested by data collected in 1997. But salinity gradients are not constant, and water samples were collected only during one 24- hour period in May 1997 and another 24-hour period in September 1997. In addition, no data has been collected after the maintenance and contamination dredging. The sampling in this case was too limited to give reasonable assurance that the proposed flushing culverts would have advantages over the required channel in promoting of flushing. Petitioner and Intervenor contend that changing the open channel to closed culverts would decrease the benefit of oxygen exchange in an open-channel system. It is true that, generally, more oxygen would be introduced in an open system. But the evidence was that none of the "net improvement" to water quality from the specific conditions to the 1995 Permit was anticipated to derive from increases in dissolved oxygen from oxygen exchange in the channel. Conversely, Applicant contended that the proposed culverts would decrease the chances of contamination from the uplands, as compared to an open channel. But there was no specific evidence to support or quantify this speculative benefit. In addition, required improvements in surface water management at the Marina would reduce any such benefits from the culverts. See, Specific Condition 5.B. and DOAH Case No. 98-5409. Approximately 60 feet of mangrove fringe would have to be removed from the north canal to accommodate a flushing channel. In contrast, only approximately 8 feet of mangrove fringe would have to be removed to accommodate the proposed culverts. But there was no evidence as to how removing less of the mangrove fringe would improve flushing or water quality. In addition, Specific Condition 12 of the 1995 Permit required replacement of the mangroves lost in the construction of the flushing channel. There was no evidence that installation of flushing culverts instead of the flushing channel required under the 1995 Permit would have any impact on manatees.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order: granting Applicant's proposed modifications to the 1995 Permit, with the following additional modifications: No use of the new travel lift for boats less than 40 foot in length except in emergencies, e.g., approaching hurricane. Limitation on use of travel lift to a 28- day rolling average of ten vessels a week, except in emergencies, e.g., approaching hurricane. Prohibition against pressure-washing and flushing bilges and engines of vessels on the new travel lift except in the boat wash area to be constructed and operated in accordance with Specific Condition 15 of the 1995 Permit. A requirement to report and promptly clean-up any spills of oil or gasoline in the north canal related to operation of the new travel lift. waiving certification as a precondition to federal permitting under 33 United States Code, Section 1341.

Findings Of Fact Based on the stipulations of the parties, the exhibits received in evidence, and the testimony of the witnesses at the hearing, I make the following findings of fact: On April 21, 1983, the College filed an application with DER seeking a permit to relocate a drainage ditch that runs through the College property, to fill the existing drainage ditch, and to install a large culvert in the Coconut Creek Waterway which would serve as a road crossing connecting the proposed new College parking lot and N.W. 39th Avenue in Coconut Creek. Upon review of the original application, DER determined that it would not meet the DER's water quality criteria. On September 30, 1983, the College revised its application. It is the revised application which lies at the heart of the present controversy. The revised application no longer contains a proposal to fill in the entire ditch that runs through the College property. Rather, it is new proposed to install two 36-inch culverts in the existing ditch to provide access roads to the proposed new College parking lot. The College also proposed to dredge 832 cubic yards from .5 acres and to install a large structural culvert (measuring 14 feet, 1 inch, by 12 feet, 10 inches) in the Coconut Creek Canal. The existing ditch which runs through the College campus was originally constructed as a drainage ditch. The only water which would flow through that ditch would be provided by run off from the N.W. 11th Street area. At the present time the ditch through the College is plugged in two places. Some time in late July or early August of 1984, contractors employed by the College placed two earthen plugs in the ditch that runs through the College. This was done without benefit of a Department permit and was apparently the result of some confusion on the part of the contractors, the exact nature of which is not explained in the record in this case. The two earthen plugs were not installed in the manner proposed by the subject application, nor were they installed in the locations proposed in the subject application. In their present condition the two earthen plugs effectively prevent the flow of any water through the ditch that runs through the College. The north end of the ditch that runs through the College campus was formerly connected to Coconut Creek Canal. A portion of Coconut Creek Canal runs parallel to N.W. 11th Street. Following the installation of the earthen plugs there was a decrease in the water quality of the portion of Coconut Creek Canal that parallels N.W. 11th Street. The water became cloudier than before and there was some silting. There were fewer base and bluegills and more mudfish. There has also been an occasional unpleasant odor from the area which was not present prior to the installation of the earthen plugs. Also, the residents along N.W. 11th Street complain of an increased mosquito Population since the installation of the earthen plugs. 1/ The proposed 36-inch culverts are substantially larger than is necessary to handle the anticipated flow of water through the College ditch. Calculations made using the methodology approved by the Florida Department of Transportation indicates that 21-inch culverts would have been sufficient to handle any anticipated flow of water through the College ditch. Although the culverts will require some periodic maintenance, they have been designed to minimize the need for maintenance. Properly maintained, the proposed 36-inch culverts will not pose any impediment to the flow of water through the College ditch. There is usually no detectable current or water flow in either Coconut Creek Canal or the College ditch in the area where the College proposes to install the three culverts. Accordingly, inasmuch as there is usually no detectable flow of water, any impediment to water flow which might be caused by the culverts is insignificant. This is particularly true with regard to the issue of weed growth. While it has been contended that the culverts might reduce the rate of water flow to the extent that aquatic weed growth would be promoted because of the stillness of the water, long before this permit was ever applied for and long before the earthen plugs were installed the City of Coconut Creek had serious problems with aquatic weeds growing in all of its canals. As described by one of the City's former mayors, several years ago the hyacinths covered the canals solid from bank to bank and were growing so thick and solid that rabbits could actually run across the canals hopping on the hyacinths. This type of hyacinth growth only occurs in still water. The City has been able to control the hyacinth problem by an ongoing weed control program which consists of spraying chemicals on the plants several times each year. The small amount of water flow which does occur in Coconut Creek Canal is directly related to stormwater runoff, including water generated by the residents along N.W. 11th Street washing their cars and watering their lawns. The portion of Coconut Creek Canal which extends eastward from the College ditch is a dead end system in which the only flushing is due to water runoff from the street. The installation of the proposed large culvert in Coconut Creek Canal would never cause the water to back up in the canal or otherwise impede the flow of water in the canal. A tube 21 inches in diameter would be sufficient to carry away the worst expected rain water conditions and the proposed culvert is, in essence, a tube with an average diameter in excess of 13 feet. The large culvert would cause no change in the volume of water flowing through the canal. It might cause a de minimis headloss, which is a change in the water level from one side of the culvert to the other. Any such headloss would be on a magnitude of approximately 1/1000th of a foot; about 1/3 of a millimeter. The installation of the large culvert in the Coconut Creek Canal would actually increase the velocity of any water flow through the culvert. In conjunction with the installation of the large culvert, the depth of Coconut Creek Canal would be increased to an average of six or six and one-half feet from its present average of approximately five or five and one-half feet. Notwithstanding the decrease in the water quality of the portion of Coconut Creek Canal that parallels N.W 11th Street which apparently resulted from the unauthorized installation of the two earthen plugs, when the water in that portion of the canal was tested by the City's export witness some eight or nine months later, the water quality was within established state standards. And while the construction activity associated with the installation of the two 36-inch culverts in the College ditch effect on the water quality in Coconut Creek Canal, there is no evidence that water quality standards would be violated on either a short or long-term basis. A small amount of habitat would be destroyed, but it is likely that there would be rapid recolonization. No rare or endangered animal species would be affected. The habitat for birds would also recolonize and the birds and fish displaced by construction would return. Any turbidity problems during construction would be controlled by the use of turbidity screens. With regard to navigability, once installed the large culvert would provide a vertical clearance from the surface of the canal of approximately six feet. This clearance would prevent larger boats from passing through the culvert. The vertical clearance of existing canal bridges in the area varies from six and one-half to eight feet. Installation of the larger culvert would not seriously impede navigation. The large culvert would not constitute a navigational hazard nor would it impede the flow of navigable water. As compared to the situation which existed prior to the installation of the two earthen plugs, installation of the two 36-inch culverts would totally stop any boat traffic through the ditch that runs through the College. Nevertheless, curtailment of boat traffic through the College ditch would not seriously impede navigation because any destination which could be reached by traveling through the College ditch could be reached via alternative canal routes which are not affected by this project. As with the larger culvert, the 36-inch culverts would not constitute navigational hazards nor would they impede the flew of navigable water. If the total project envisioned by the College is completed, the culverts will provide a new route for motor vehicle access to an expanded College parking lot. The increased volume of motor vehicle traffic would produce an increased amount of air and noise pollution in the vicinity of N.W. 39th Avenue. A study of the results of the increased motor vehicle traffic based on a "worst case" scenario reveals that even with the additional air and noise pollution generated by the increased motor vehicle traffic, the air and noise pollution levels in the area would be far below the air and noise pollution standards established by the state and federal governments. In the formulation of the foregoing findings of fact I have, of necessity, relied to a large extent on the opinions of expert witnesses who testified in the case. Where there is conflict in the testimony of the expert witnesses, I have generally credited the testimony of the expert witnesses called by the College and the Department because I have found their testimony to be more consistent with other evidence in the case and have found that there is a better factual foundation in the record for their opinions than for the opposing opinions.
Recommendation For the foregoing reasons it is Recommended that the Department issue a Final Order which would GRANT the College's application to install two 36-inch culverts in the College ditch and a 14-foot, 1-inch, by 12-foot, 10-inch, culvert in the Coconut Creek Canal, subject to the conditions set forth in the Department's Notice of Intent to Issue. DONE and ORDERED this 8th day of October, 1984, in Tallahassee, Florida. MICHAEL M. PARRISH Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 8th day of October, 1984.
Findings Of Fact At all times to the issues herein the Department of Environmental Protection was the state agency in Florida responsible for the regulation of water pollution and the issuance of dredge and fill permits in the specified waters of this state. Mr. Byrd has been a resident of the City of Treasure Island, Florida for many years and resides at 123 123rd Avenue in that city. His property is located on Boca Ciega Bay next to a public boat ramp operated by the City. On April 12, 1995, the City of Treasure Island applied to the Department of Environmental Protection for a permit to construct a dock six feet wide by seventy-five feet long, located on the edge of its property on which the public boat ramp is located. This property is located in a basin off Boca Ciega Bay, which is classified as a Class III Outstanding Florida Water. The dock involves the placement of pilings in the water, and the construction of a walkway thereon. In order to be obtain a permit, the applicant must provide the Department with reasonable assurances that the proposed project will not degrade water quality and will be in the public interest. The project is permanent in nature, but the temporary concerns raised by construction have been properly addressed in the permit. In the instant case, the dock is intended to accommodate the boating public which will utilize it to more safely launch, board, debark, and recover small boats at the ramp in issue. The dock will be equipped with a hand rail which will increase the safety of the project. Evidence establishes that without the dock, boaters have to enter the water to launch and recover their boats on a ramp can be slippery and dangerous. The site currently in use as a boat ramp, a part of which will be used for the dock, is almost totally free of any wildlife. No evidence could be seen of any sea grasses or marine life such as oysters, and there was no indication the proposed site is a marine habitat. Manatees do periodically inhabit the area, and warning signs would be required to require construction be stopped when manatee are in the area. The water depth in the immediate area and the width of the waterway is such that navigation would not be adversely impacted by the dock construction, nor is there any indication that water flow would be impeded. No adverse effect to significant historical or archaeological resources would occur and taken together, it is found that the applicant has provided reasonable assurances that the project is within the public interest. Concerning the issue of water quality, the applicant has proposed the use of turbidity curtains during construction which would provide reasonable assurances that water quality would not be degraded by or during construction. The water depths in the area are such that propeller dredging and turbidity associated therewith should not be a problem. No evidence was presented or, apparently is on file, to indicate any documented water quality violations at the site, and it is unlikely that water quality standards will be violated by the construction and operation of the structure. The best evidence available indicates there would be no significant cumulative impacts from this project. Impacts from presently existing similar projects and projects reasonably expected in the future, do not, when combined with the instant project, raise the possibility of adverse cumulative degradation of water quality or other factors of concern. By the same token, it is found that secondary impacts resulting from the construction of the project would be minimal. It is also found that this project is eligible for an exemption from the requirements to obtain a permit because of the Department's implementation on October 3, 1995 of new rules relating to environmental resources. However, the City has agreed to follow through with the permitting process notwithstanding the exemption and to accept the permit including all included conditions. This affords far more protection to the environment than would be provided if the conditions to the permit, now applicable to this project, were avoided under a reliance on the exemption to which the City is entitled under current rules. To be sure, evidence presented by Mr. Byrd clearly establishes the operation of the existing boat ramp creates noise, fumes, diminished water conditions and an atmosphere which is annoying, discomfiting, and unpleasant to him and to some of his neighbors who experience the same conditions. Many of the people using the facility openly use foul language and demonstrate a total lack of respect for others. Many of these people also show no respect for the property of others by parking on private property and contaminating the surrounding area with trash and other discardables. It may well be that the presently existing conditions so described were not contemplated when the ramp was built some twenty years ago. An increase in population using water craft, and the development and proliferation of alternative watercraft, such as the personal watercraft, (Ski-Doo), as well as an apparent decline in personal relations skills have magnified the noise and the problem of fumes and considerably. It is not likely, however, that these conditions, most of which do not relate to water quality standards and the other pertinent considerations involved here, will be increased or affected in any way by the construction of the dock in issue.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: RECOMMENDED that the Department of Environmental Protection issue to the city the requested permit to construct the dock in issue at the existing public boat ramp at the east end of 123rd Avenue right of way in the City of Treasure Island. RECOMMENDED this 12th day of December, 1995, in Tallahassee, Florida. ARNOLD H.
