Findings Of Fact Petitioner, the Association, represents 1,053 condominium homeowners located in the Old Port Cove Community, a residential development in Palm Beach County, Florida. Old Port Cove Community consists of seven separate condominium buildings and associations. Many of the individual condominium homes/apartments within the complex border on arid overlook the Old Port Cove area of north Lake Worth which is the location of the two existing marinas operated by the Respondent Applicant and the site of the proposed marina expansion. The water in question is an essential part of the residential community and was, in many cases, a major factor considered by the homeowners purchasing in this community. At the time of development, going back a minimum of seven years, property owners were advised by the developer/Applicant (or its predecessor) that the marinas constructed or to be constructed would be for the exclusive use of the residents of the condominium apartment houses within the complex. On or about March 12, 1986, Respondent DER, received an application from the Applicant for a dredge and fill permit for the construction of a commercial addition to the northernmost marina currently existing at Old Port Cove Complex. The new construction was to consist of 1 pier of a total length of 911 feet with 50 boat slips and 26 finger piers. The new slips will be 45 feet in length of which 15 feet will consist of pier and the remaining 30 feet of open water terminated by a piling. The main pier would extend in a northeast direction from the easternmost point of the existing north pier for a total of 171 feet, then turn northwest for a total of 490 feet, and then turn southwest for an additional 250 feet to enclose an area of water leaving a 90 foot wide space for entry of boats into the enclosed area. The application for the permit contains as an attachment thereto an engineering drawing depicting the proposed marina expansion and its relationship to the existing marina. This expansion was proposed because of the growing need for boat slips in the area. The operator, currently providing a total of 289 slips in both marinas, (197 in the south and 92 in the north) proposes to construct 50 new slips for pleasure boats from 25 to 120 feet in length. Applicant proposes and commits itself to utilize the new slips for sailboats only. Notwithstanding the fact that there are approximately 1,261 additional slips available within a one mile area of the proposed site, the applicant contends it has been continuously turning away applicants for slip rentals in its facilities. If approved, the proposed new facility will constitute an approximate 4 percent increase in the total number of boat slips in the area, not counting the free moorings offshore in the Federal mooring in the center of the cove. Applicant presently operates one diesel fuel pump at the South Marina. No other fueling facilities exist at either marina operated by Applicant nor are any additional fueling facilities intended. Applicant has also entered into a contract with a local fuel spill control company to provide spill cleanup if necessary. At the present time, there are no pump-out stations for sewage at either the North or South Marina. Applicant proposes to install sewage facilities as a part of the approval package. Leasing agreements currently in effect require all boats using the marinas to certify they have U.S. Coast Guard approved heads on board before being allowed to dock at the marina. This requirement is not actively enforced, however. Most boats utilizing the facility are pleasure/non-commercial fishing boats. Individuals, mainly residents of the apartment complex, use the docks for fishing but there is some question as to the nature and availability of the fish population in the area. Manatees do frequent the area, however, not necessarily as far north as the marina in any great numbers, but several hundred yards to the south, congregating at times around the entrance to the intracoastal waterway which forks off to the northwest somewhat south of the south marina. Subsequent to the receipt of the Association's Petition herein, DER had numerous water quality tests performed and requested certain assurances from the Applicant designed to remedy or rectify numerous objections made by the Association in its Petition. Thereafter, on February 16, 1987, DER issued a Revised Intent to Issue in this case in which it addressed the Association's concerns and specified certain conditions to be included in the permit to protect the water quality and biological resources in the project area. These conditions included: A prohibition against commencement of any excavation or other construction activity prior to receipt of evidence of permission from the Trustees of the Internal Improvement Trust Fund or DNR; A requirement for notification of the Division of Archives in the event any historical or archaeological artifacts are discovered within the project site; Provision for permanent sewage pump-out facilities to be provided at the south marina to replace portable facilities currently available, within 90 days of permit issuance, and the provision of temporary sewage pump-out facilities at the north marina which shall be in place and functioning prior to any work being commenced under the permit; The requirement for use of turbidity screens around the project site during construction to remain in place until turbidity behind. The screens falls to an acceptable level; The placing of educational signs, the content of which shall be coordinated with DNR, at both the north and south marinas, informing boaters that manatee may be in the area and requesting that care be taken; The posting of manatee warning signs in both marinas; The establishment of idle speed and no wake zones in both marinas and the access channels; A provision that permanent liveaboards connect their vessels with permanent sewage hook-ups at all times when the vessel is docked; and A provision against refueling facilities at the expanded north marina. Applicant and DER are satisfied that the conditions imposed by the terms of the Revised Intent to Issue satisfy all the current requirements of the statute and rules relevant to dredge and fill permits for projects of this nature. Many of the apartment owners, banding together as the Petitioner Association herein, strongly resist approval of the permit to construct the new marina for numerous reasons. They contend, first, that the construction of the new marina and the greater number of boats resulting therefrom, constitute a threat to the manatee population in the area. The Association is also concerned with water quality in the area, fire safety, wake damage, and noise pollution as a result of the proposal. Other considerations of the residents include parking and a diminishment in the resale value of their property. Several of the residents have seen manatee in the area swimming in the waters adjacent to the marina and in the "key" area on the other side of the peninsula. Many have scars on them and appear to have been injured by collisions with boats. Several residents have seen trash and debris in the water and have observed boats traveling at a high rate of speed just outside the existing marinas. In addition to debris, residents have seen oil and grease floating on the water and contend that the proposed wave baffles hanging down into the water from the extended pier will interfere with the natural flushing action of the winds and tides. Many of these same individuals complain of an extremely bad odor coming from the marina and they have observed boat owners either pumping their bilges directly into the marina water or washing their boats with detergents which are allowed to run overboard into the water. At least one resident, speaking for others as well, referred to a green space, an area of grass outside and between the buildings and the water. Originally, this area was supposed to be gardens and a recreational area for the residential complex, and the yacht club was to be a secondary appurtenance for the property owners. Now, with apartment owners making up no more than 10 percent of the occupants of the marina slips, for it seems as though the apartment residence owners are being shunted to the background and commercial activities, including the marina, are becoming paramount in the eyes of the applicant which still operates it. This green space is now proposed to be converted by the applicant to parking for the use of the marina patrons; all to the detriment of the apartment owners. There is some evidence that boat owners utilize the grounds of the apartment complex as a place to walk their dogs for canine toilet purposes and there is some evidence that numerous liveaboard boat owners, who do not have adequate toilet and bathing facilities on board their boats, utilize the pool, showers, and toilets ordinarily reserved for residents of the apartment complex. Noise from parties on the boats is often both excessive and disturbing and to the knowledge of at least some of those testifying on behalf of the Association, efforts by security personnel employed by the condominium associations to get the boat owners to curb the noise and disruption have been totally unsuccessful. One resident summed up the feelings of his co-owners when he indicated that these various factors translate to property value and because of the current situation with pollution, noise, lack of security, and the increasing commercialism, the result has been a substantial drop in property value. This witness feels that the more slips that are made available, along with their related annoyances, the less the value of the individual apartments will be. All feel that the addition of 50 more slips will increase the existing problems and none of the residents who testified for the association were of the opinion that the developer's controls will be adequate to alleviate or minimize the untenable situation which they now face. However, there was no evidence presented to substantiate the layman opinion of reduction in property value and it cannot be said, therefore, that this has or will really happen, and the amount of loss. Turning to the issue of water quality as effected by refueling operations and sewage disposal at the marina, the question of fueling facilities was not raised by the Association other than to object basically because of the potential for fuel spills. Applicant and DER contend that this problem should be taken care of through the contracting for the services of Glasgow Equipment Service, providing for 24 hour emergency response for fuel spills of any type. It is unreasonable to expect that a marina providing dockage for potentially as many as 289 motor vessels can be expected to be totally spill free. If proper refueling procedures are followed, and there is no evidence to indicate that they would not be, the incidence of fuel spills should be minimal and the contract with the clean-up service providing for around the clock response in case of a spill, appears to be adequate action to remedy the effects of any spill. There have been very few fuel spills in the history of the marina operation. The most recent resulted in a spill of no more than 3 to 5 gallons and clean-up was successfully accomplished with little damage. The Association made much of the fact that no disciplinary action was taken against the offender and that the boat in question is still an occupant of the marina. This incident is still under investigation, however, and final action has not yet been taken. At the current time, there are no pump-out stations for sewage at either the north or south marina. The applicants propose to install a pump-out sewage facility tied to each vessel berth in the south marina and to provide a portable pumpout facility which can be rolled to a particular spot to meet the needs of any vessel at the north marina. The Applicant has agreed to fund the project completely and has agreed to the special conditions contained in the Revised Intent to Issue regarding the pumping stations. Applicant and DER both arranged for testing of the water quality at the north marina to determine the current condition of the water. Dr. John D. Wang, an expert in coastal hydrodynamics on the faculty at the University of Miami, is familiar with the site of the proposed expansion and visited it last in November, 1986. At that time, he did a study on the flow exchange caused by tides and wind over a two day period. As a part of his test, he placed instruments in the water to take measurements of water motion, temperature, and salinity on the outer side of the current pier at the north marina and inside that marina at different depths. On the first day of the test, the tide was an ebb tide (receding) pulling water out of the marina area. However, at the same time, the wind was from the southeast which directly opposed the tide action. At the surface, the drogues (instruments) followed the wind. Those deeper in the water went with the tide. When the tide came in the next day, the drogues went to the north under the power of both wind and tide. Dr. Wang's experiment confirmed not only that the water moved in and out of the marina area, but also that the water circulated clockwise north along the west side of Lake Worth and south on eastern side. Dr. Wang thought this might be due to wind force, but regardless of the cause, it was a good indication that water was exchanged in the area. Dr. Wang concluded that the water in the marina was completely taken out within one hour and joined the circulatory pattern, being replaced by other water. The baffles placed on the piers to reduce wave motion will have some effect on the water circulation tending to reduce surface flow, but these baffles will not prevent the exchange of water due to circulation because they are limited to the top three feet of the water. In Dr. Wang's opinion, they may have some positive effect on circulation by preventing wave water from flowing back out. By the same token, the presence of boats in the marina will have but a marginal effect on water exchange. The draft of the boats utilizing this area is not much more than the wave baffles and there will still be ample water underneath to permit flow and exchange. In fact, in Dr. Wang's opinion, the location of this marina is almost optimal. By virtue of the fact that it is out in the open, water can flow freely through the area and no dredging is required. The flat, sloping bottom promotes water exchange. No evidence was presented to contradict this opinion and it is hereby accepted. Additional tests on water quality were run by Dr. Paul R. McGinnes, head of an independent consultant laboratory specializing in water quality and motion who visited the site several times doing three separate studies of dissolved oxygen, salinity, and water temperature at various depths and at different hours. As a part of his examinations, he also looked for oil (pollutants), and bacterial components. The water subject to tests for bacterial components was taken from the top foot at several locations in each of the three studies. In the 1983 study, tests showed fecal and coliform bacteria were present in sufficient quantities to constitute a few violations. In 1986, when he sampled for fecal bacteria only, the count was very low. In the 1987 test of samples taken twenty times over 24 hours, the fecal bacteria count was, in each case, within state limits. As to heavy metals, in 1983, levels of lead, cadmium, mercury, and zinc were not present. There was no evidence as to current levels. As to oils and greases, all studies showed very little present (below 5mg per litre) and what grease was there could consist of animal or vegetable fats. This is considered unlikely and it is found there is petroleum product in the water, though in insignificant quantities. Regarding dissolved oxygen, all tests showed compliance with state standards. Levels were comparable to other areas of Lake Worth. Dr. McGinnes is generally familiar with the state standards for Class III waters and believes the construction and operation of the new 50 slips at the north marina will in no way result in violation of state water quality standards. His opinion as to this construction is based on his tests, his conversations with applicant's personnel, and his experience with other similar projects. Granted, boats do tend to leak oil and that situation will raise the oil level in the immediate area of the leak. However, not all boats leak in all marinas and what leaks there are will tend to dissipate to a safe level within a very short period of time. In February, 1983, the coliform bacteria in the south marina were higher than in the north marina or in Lake forth in general. However, coliform bacteria does not appear to be a major problem in this case. In response to cross examination, Dr. McGinnes concluded that even if five boats dumped raw sewage in the north marina, it would not have any major negative impact on the overall water quality there. It would, of course, affect the sample taken in the area immediately after dumping, but not the overall quality over the long run. Dr. McGinnes' last sample was taken in February, 1987, which is a time of highest use. The water quality in and around the marina is generally as good as in the northern end of Lake Worth which is better than in the southern end of the lake. His examination of the water quality indicated no recognized violations of Florida water quality standards in the last two reports. The association's expert, Mr. Timmer, went to Old Port Cove in January, 1987 and saw numerous boats in the slips. He looked for inlets opening into the marine and for a bird population, either one of which could cause an increase in undesirable bacteria in the area. He found none. He took water samples for testing to see if the fecal coliform bacteria level in the marina was higher than outside it. During his tests, he took samples from 14 sites at three separate depths at each. His samples were duplicated for safety in case any one sample was compromised. Six of his samples were taken inside the dock area of the north marina; one was taken to the north several thousand yards; and four more were taken outside the area of the proposed marina. One was taken in the federal anchorage; several across the cove on the east side of the lake and one outside the cove, south of the Intracoastal Waterway inlet and west of the channel. The furthest test site was approximately one mile from the marina. When Mr. Timmer got his samples, he isolated the sets from each other; "refrigerated" them (placing them in a cooler without any ice), and upon completion of his sampling, took them to the McGinnes lab where analyses were done for fecal coliform bacteria. As a result of his tests, and relying on the report received from McGinnes Laboratories, Mr. Timmer concluded that the fecal coliform level within the marina was higher than outside the marina by 5 to 10 times. Surface samples, he felt, averaged out in excess of what he considered to be the state standard. Some of the lower level samples were high also. In no case, however, did any sample exceed a count of 15 outside the marina. Coliform standards, according to state rules, are to be averaged over a month's period of taking. In fact, the report received from the McGinnes lab concluded that because testing was not done over a month's period, the standard was not exceeded. These samples, even that one reflecting a reading of 560 bacteria per 100 ml at site 3a, did not come anywhere near the upper limits of the state standard and in fact was well within it. Mr. Churchill, a zoologist and ecologist and expert in marine biology made various studies of the benthic communities and fish population in the area of the proposed construction. He studied the soft bottom communities and took samples of the bottom in different areas both inside and outside the current marina and in the area where the extension is proposed. He found that the outside and the outer inside communities were much the same and had a low number of species. The inner inside was considerably different. It had a higher number of both species and individuals. A larger number is a better system and DER rules provide that one cannot build a project which would tend to reduce the number. Here, since the area where the construction is planned is outside the area of high species count and similar to the rest of the cove area, the construction would most likely not violate the state's rule. In fact, in Mr. Churchill's opinion, concurred in by other experts, the proposed project will, rather than negatively impact the environment for wildlife, enhance it by providing additional habitat. The pilings, forming supports for the piers and ties for the boats will provided habitat for small marine life which in turn provide food for larger life which is attracted. This testimony would tend to contradict the testimony of at least one of the residents who indicated that in his experience, the fish population in the area had declined radically over the years since he moved in and that about all one can catch in the immediate area now are some small sheepshead. This is in comparison to the larger variety and size of fish available to the angler several years in the past. No doubt, the fish selection and availability has diminished since the area was developed, but the question is whether the new construction will aggravate that situation and the answer appears to be that it will not. An additional water quality study was conducted by Dr. Martin Roessler, a marine scientist who did a water quality study in the area consistent with that done by Dr. McGinnes. He also did several of his own on- site inspections as to water clarity and marine plant and other life including reptiles and birds in the area. On his third visit to the site, he took water quality samples for testing for bacteria and other marine life. As a result of his tests, he concluded that water quality in the area should not be diminished by construction of the marina. During construction, the use of turbidity curtains and booms will tend to keep any temporary disruption to a minimum. He agrees with Dr. McGinnes and Mr. Churchill that the nature of marine life within the area should not be disturbed by the construction. He was unable to observe any sea grasses in the area (they are on the other side of the cove and not where he observed) and dredging would not be involved; only the driving of pilings which will disrupt the bottom only in the immediate area of the piling. Dr. Roessler's credibility was not damaged by the Association's evidence that a previous study done for another agency was rejected and he was not paid for the work done. There was insufficient evidence of detail and a broad-brush smear can not be held effective here. When Old Port Cove submitted it's application for its permit, it included the original draft and all requested information in a final product. This project documentation was evaluated by Ms. Janet Llewellyn, a supervisor with DER, who is an individual fully conversant and familiar with the dredge and fill rules and standards set forth in the statutes and the F.A.C. As to water quality, Ms. Llewellyn analyzed the information submitted by the applicant in response to her request for water samples at certain locations she had identified. These samples showed no current violation of the rules governing dissolved oxygen and fecal or coliform bacteria even with the boats that are currently in the marina. DER also requested "hydrographic information as a part of the reasonable assurance" test and this information was to deal with existing water quality and the flushing action of the tides and winds. Ms. Llewellyn has visited the site, albeit only shortly before the hearing, and as a result believes that the drawings submitted with the permit application are correct and represent the work to be done accurately. Recognizing that the field inspection report submitted by on-scene local DER personnel is somewhat negative in its evaluation of the project, she nonetheless disagrees with certain portions of this report which say that boats and piers will interfere with the flushing action of the wind and tide. She also disagrees with the statement that oil and grease will continue to degrade water quality. She feels that the inspector who did the report did not have available to him the hydrographic and water quality tests that she had. This information, submitted somewhat earlier, was sent to Tallahassee by the experts and was not forwarded to the field representative when the request for the survey was laid on. The Revised Intent to Issue, including as it does, the additional requirements laid on the applicant in such areas as sewage pump-out, liveaboards, fueling facility prohibitions, and the like came about as a result of misunderstandings between DER and the applicant and culminated in the applicant agreeing to try to ameliorate the situation and the issuance of the permit by compromise as suggested. DER is satisfied with the proposals contained in the Revised Intent to Issue and feels that approval of this permit will upgrade the facilities at the south marina as well as insure compliance with state water quality standards at the north marina. Together it will result in an upgrade in the water quality in the area. Ms. Llewellyn is convinced that there will be no negative effects on the water quality by the construction at the north marina and that the criteria contained in both the statutes and the rules, from an environmental standpoint, will not be violated. DER has no authority to consider other factors which appear to be among the most substantial complaints of the association members. She did not consider the possibility of damage to the scenic view by the addition because she did not consider it to be an issue. In her opinion, the question of damage to the property of others relates to damage to structure, property, wildlife, etc., and the impacts to these would be negligible. What she considers important is that the permit involved here is for construction, not operation of the marina and enforcement of continuing operational rules is another consideration entirely. When using the term "assurance" as a requirement for an applicant, the assurance required is not that the new slips will have no adverse impact, but that any adverse impact will not reduce the water quality below standards set out in the statutes and rules. Though not envisioned, water quality can be reduced from very high quality to high quality (a reduction in quality) and still be within standards. Additional scientific examination of the water and the immediate site was conducted by Dr. Kenneth L. Echternacht, a hydrographic engineer, physicist, and physical water quality expert with DER who reviewed the hydrographic study submitted with the application. He found that the drogue study showed water speeds of between .05 to .1 feet per second which was typical of the area. The placing of drogues and the resultant study and conclusions was not flawed by the lack of education of the individual who did the placing at the direction of the scientist. What is important is the education and knowledge of the supervising scientist who will take the information gathered and examine it. Considering that prevailing winds in this area during daylight hours are from the sea to the land, (SE to M), and at night the reverse occurs, any study made only during daylight or during nighttime would be flawed to the extent that it would examine only one part of the equation. Given the baseline information available to him, Dr. Echternacht concluded the project as described would not adversely effect water quality from a hydrographic standpoint. Flushing and circulation are important to water quality. If the water does not move, the pollutants added by outside factors, (here boats), accumulate and build up. On the other hand, the faster the water moves, mixed with turbulence, the faster the pollutant is disbursed and prevented from accumulating. At .05 f/sec, a particle of water would move 180 feet per hour. As a result, water will move the length of the marina, (450') in 2 1/2 hours. Therefore, if a spill occurred at the south boundary during an incoming tide, it would move to the north boundary of the marina within 2 1/2 hours and given a tide cycle of 6 1/2 hours, would still have 3 1/2 to 4 hours to move even further away, mix with other water, and be disbursed before being brought back to the marina by the outgoing tide. (However, there is evidence that the water moves in a clockwise direction and the likelihood is great that the contaminated water would not even come back to the marina but would head out down the eastern side of the cove.) This is a worst case situation because of the slow water movement rate utilized and it is, itself, a relatively fast movement. Admittedly, this water movement will be affected by obstacles in the water such as boat hulls, posts, pilings, and baffles. However, while these factors would slow up the water, they would also create turbulence and vortices in the water which, themselves, help mixing. From a practical standpoint, other factors are involved such as the size of the obstacle, etc. Here we are faced with a situation where the marina is not enclosed and the water flows freely. The water quality can be expected to be better than in an enclosed marina and even better in the new area than in the existing areas because it will be further away from the seawall. Taken together, in light of the evidence presented by both sides, it is found that a diminishment in water quality as a result of the construction of the proposed facility here would be minimal and would in no case, likely result in a reduction of the water quality to a level below that considered acceptable in the state statutes and rules. In addition to water quality, the residents were concerned about the threat of injury to the manatee population which, while not appearing in the immediate area of the proposed construction on a regular basis, does visit the area periodically. In addition, there is substantial evidence to establish that boats coming into and out of the marina, going down through the channel into the main part of Lake Worth and out through the cut, would pass through areas actively populated and visited by manatees and therefore, the opening of 50 additional slips for new boats, even in this less populated area, could have a substantial impact on the manatee population. There is no doubt that manatees do visit the area. There are sea grasses, if not in the immediate area of the proposed marina, certainly on the opposite shore of the north part of Lake Worth. It is uncontroverted as well that manatees have been seen near the marina and in the key area on the other side of the peninsula. However, the evidence introduced by the association's own witnesses, Mr. Rose and Dr. Odell, indicates that the manatee population tends to congregate in areas south of the entrance to the Intracoastal Waterway which, itself, is south of the Old Port Cove area. Many manatee congregate in the warm waters produced by the Riviera Beach power plant in the southern part of Lake Worth and go from there to other areas within the Lake Worth area to feed, even as far north as Hobe Sound and Loxahatchee. Generally, there are not enough sea grasses in the local area to keep them there. Manatees can range up to 12 feet in length and up to 3500 pounds in weight. Manatee deaths in Palm Beach County, of which boat deaths account for approximately 50 percent, are a serious danger to the survival of the manatee population. The greatest danger to manatees comes from power boats. While there is no evidence that sailboats are dangerous since they move slowly enough for the manatee normally to evade then, there nonetheless may be some danger as a result of their presence. Some manatees are crushed by barges and larger power boats. Some are killed by impact with medium and larger boats. In approximately 40 percent of the cases, impact kills without propeller injuries and it is hard to tell the size of the boat which did the damage. As to propeller deaths, boats from 24 feet up can kill by this method. The number of manatee deaths has increased lately as a result of boat and other man related causes and if this trend continues, the manatee population will decline and, possibly, become extinct. Mr. Rose, who is quite familiar with the habits of the manatee in this area, states that it is most likely that in traveling north to Hobe Sound and environs, the manatee would travel up the Intracoastal Waterway (the entrance to which is south of the proposed construction) and not go into the Old Port Cove area. Even if they were following the grass which runs along the east and north shores of Old Port Cove, the grass does not grow on the marina side and it is unlikely the manatees would come to the marina in the west to feed though they might come for other reasons and in fact have been seen in the "key" area. Dr. Odell, perhaps the foremost authority on manatees in the United States, has visited the area and, at this hearing, heard the testimony of the other witnesses. He contends that because of the food available in the form of sea grasses and mangrove seeds, primarily on the eastern side of the cove, the likelihood is that manatees would be found in that area. This is consistent with the testimony of Mr. Rose. Consequently, it is found that while manatees come to the area of the proposed marina from time to time, it is more the stray manatee than evidence of continued habitat. Dr. Odell's studies indicate that between 1974 and 1985, there were no manatee deaths recorded in north Lake Worth. However, it is possible that the dead manatee found elsewhere may have been injured or even died elsewhere, (possibly near Old Port Cove) and there well may have been others who were injured in the area who went elsewhere to die. There is, however, no evidence that this is the case. Dr. Odell considers that boats with a draft of between 5 and 7 feet would leave little clearance from the bottom in the bottleneck area south of the marina where the water depth is no more than 9 or 10 feet, to allow room for the manatee to avoid them. In fact, he feels that large, inboard powered boats pose the greatest threat to the manatee. While sailboats generally do not create a risk to the mammal, if the new 50 slips were to be limited to sailboats but all existing slips were to be converted to power boats, this would constitute a severe threat to the manatee population. Further, a change in use patterns, creating more traffic, would increase the risk to the manatee. The real issue is, however, how much time boats spend in manatee habitats. The more boats there are, the less desirable the situation. (Both experts agree, however that if the 50 new slips are limited to sailboats and the ratio of power boats to sailboats in the existing slips is not increased, there is really no legitimate reason, based on a threat to the manatee population, to deny this construction permit.) It would appear, then, that the risk to the manatee population is acceptable. Signs advising boaters to slow down and beware of manatee are good only so long as they promote awareness. There is, according to Dr. Odell, no evidence that they have reduced manatee mortality and given present trends of more power boats and the destruction of the manatee's habitat, one can expect the manatee population to decrease even further.

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 Petitioner Melvin J. Laney is the owner of Rodriguez Key which is located approximately one and one-half miles from Key Largo, Florida, in the Atlantic Ocean. The island consists of about 170 acres and is undeveloped. It is approximately 9/10 of a mile long and 3/10 of a mile wide. By application, dated July 31, 1978, Petitioner requested a permit from Respondent Department of Environmental Regulation (DER) to conduct specified activities incident to the establishment of a primate breeding and research farm. The proposed activities included the construction of a floating pier, filling a sunken barge which is located 100 feet from the shoreline with coral rock and riprap, constructing two buildings on stilts on the east end of the island, clearing some 8.9 acres of black mangroves to provide trails for the placement and servicing of cages, installation of prepackaged waste treatment units, and temporary cages. (Testimony of Petitioner, Exhibits 1,8) DER's South Florida branch office personnel reviewed the application and issued an intent to deny the requested permit by letter of March 8, 1979, for the reason that Petitioner had failed to obtain local approval required pursuant to Section 253.124,. F.S., and that violations of State water quality standards could be expected by the proposed project. Further, the notice noted that the project would result in adverse effects to marine productivity and wildlife population contrary to the public interest under Chapter 253. Petitioner thereupon requested a hearing. (Petition, Exhibit 6,8) Petitioner plans to bring rhesus, squirrel, and other research primates into the State for the purpose of establishing a breeding and research farm on Rodriguez Key. The primates would be owned by sponsors who would pay Petitioner to provide housing, care and associated services. The project is designed to meet the needs of researchers for the testing of vaccines and other scientific purposes. There is currently a shortage of primates in this country due to a 1978 embargo on the export of such animals by the government of India who had previously been the primary supplier of research primates. (Testimony of Petitioner, Darrow, Exhibit l) Petitioner intends to fill a partly sunken barge near the northeast shoreline with boulders and riprap, cover it with a concrete floor, and construct a floating pier approximately 130 feet long between the shore and the barge for off-loading of supplies and equipment. The project contemplates the construction of an animal care house and a residence, both to be placed on stilts which will each contain a maximum of 10,000 square feet of space. No filling or dredging is planned for either structure. This is a modification from the original permit application which called for some 3,000 cubic yards of fill at the building site. At the western end of the island, Petitioner plans to install 16 rows of prefabricated cages with 64 cages per row, which represents a total area of approximately 12.48 acres. About 4.16 acres of that area will be cleared or otherwise disrupted to place and connect the cage rows. The cages will be secured and there is little likelihood that the animals will escape. Under a current permit from the Fresh Water Game and Fish Commission, the holding cages must be constructed to withstand hurricanes, surge and wind, and provide adequate protection for the animals during such storms. They must also meet or exceed minimum pen specifications established by the Commission. The permit submitted in evidence expired on June 30, 1981. The cages will be prefabricated and placed on metal pilings which are attached to underground rock. There will be troughs located underneath a grate floor for animal wastes which will be collected and pumped to a sewage disposal system. In order to take supplies, materials, and animals to and from the cage area, Petitioner intends to clear a 20-foot wide perimeter "trail" around the island which would be attached at both ends by lateral similar trails. The total distance of the trails is approximately 9,000 feet. The need for a perimeter trail is to deliver materials on one side of the island, service the animals, and then leave by a different route for the purpose of transporting employees, ill animals, or transporting of any animal that might affect the control area for testing and conducting vaccine research. The perimeter trails are designed to be no closer than 75 feet from a red mangrove fringe border around the island. For transportation purposes, it is proposed to use gasoline powered "all terrain" wheeled vehicles which will traverse the trails along two parallel two-inch diameter cables suspended horizontally 36 to 48 inches above the ground level. The cables will be attached to concrete anchors consisting of four inch by four inch steel tubes which are placed at 100 foot intervals along the trails. The tubes will be either hand-driven into subsurface rock several inches or driven by means of a portable pile driver. The tubes will additionally be supported by a concrete block "dead man" attached to a 5/8-inch cable on either side of the tubes and placed underground. Turning platforms would be placed at trail intersections on top of the cable road so that a vehicle could drive upon the platform and execute a turn to a connecting cable road. The low pressure tread vehicles used to traverse the roads will be equipped with shoes or flanges on the inside of the tire rims to securely ride on the pretensioned cables. They will also have low pressure pneumatic tires. The vehicles will also be used in interior areas where mangroves are not present. They will ride on the ground or upon metal plates. These areas are covered with about 9,000 square feet of batis (saltwort) cover which eventually will be killed by vehicle use. Batis is important for sediment stabilization and its removal can cause siltation problems in waters surrounding the island. The need for a 20-foot swath for the cable road is explained by the fact that transport of the 17-foot cages must be accomplished by placing them sideways on the transporting vehicles in order to install and periodically provide service, repair or replacement. A soil study made in representative areas of Rodriguez Key except the west end shows that coral rock exists at levels of approximately 11 to 15 feet below the ground surface, thus necessitating the use of pilings for support purposes rather than shallow footings. Although no soil borings were taken at the west end of the island, the soil expert is of the opinion that the borings reflect general rock characteristics of the entire island. Petitioner's civil engineer who designed the current cable road system prepared several alternative methods of construction, and is of the opinion that suspension of the cables at a height of 15 feet instead of three to four feet as currently planned would be feasible except for cage servicing purposes. A further alternative that was proposed by Petitioner's engineer expert is to place the cages at the east end of the island and utilize a boardwalk constructed of an eight-foot wide precast concrete slab walkway as a boardwalk for positioning of the cages. Six inch by six inch timber posts would be driven to the hardrock layer for a minimum of ten feet to anchor the Platform. The engineer testified that this alternative would be cost effective if used in lieu of the cable road. Respondent's Environmental Specialist testified that such a modification to concentrate the project on the east end of the island would be recommended because it would eliminate the cable road and its adverse environmental consequences Rodriguez Key is almost completely vegetated by mangroves with a red mangrove fringe around the perimeter and black mangroves on the higher interior areas. Some of the red mangroves are 100 to 150 feet in height and the black mangroves range from 20 to 40 feet high. In the east center of the island is an open area of batis, and red mangroves are located in the center and west end of the island. White mangroves are also present in the south side of the island. Throughout the island, there are watermarks on trunks and prop roots ranging from four inches to six inches, and an abundant growth of brown algae. Such algae requires regular submergence to exist. No significant forms of wildlife are present on the island. Batis is a submerged species which is important for sediment stabilization. In order to clear the 20-foot wide trails with cable suspensions as low as 36 inches above ground, it will be necessary to prune or cut back a large number of mangroves to that height. However, the prop roots of the red mangroves extend above six feet in some areas. If the trees and roots are cut to a three-foot height, it is unlikely that they would survive. Red mangroves produce leaf detritus which forms a part of the food chain for marine life. Such trees are island stabilizers which provide filtration and uptake of nutrients associated with runoff and intertidal waters. The waters surrounding the island are categorized as Class III waters under State regulations. The presence of brown algae on prop roots is evidence that the island is regularly inundated to some degree. Turtle grass, which is an indicator of regular tidal flushing, is in abundance on the flats waterward of the island but not found in the interior. During a visit to the Rodriguez Key in 1981, DER personnel observed standing water across the entire island to a depth of from one inch to one foot at high tide. (Testimony of Carroll, Key, Helbling, Exhibits 6, 8) Thirteen public witnesses testified at the hearing, including residents, landowners, and representatives of housing developments in the Key Largo area. They were uniformly opposed to the proposed project for a variety of reasons. Primarily, they fear that the presence of primates on the island a short distance away from Key Largo will produce excessive noise, odor, and water pollution in the adjacent waters which are used for recreation. Additionally, some are of the opinion that their property values will decrease as a result of the activity. A District Naturalist employed by the Department of Natural Resources at the nearby Coral Reef State Park testified that her agency opposes the proposed activity due to concern that it will cause degradation of water quality in the surrounding waters and that increased boat traffic could damage the shallow coral reef beds which lie near the State park. There is also general apprehension among the nearby residents that a hurricane could destroy any facilities on Rodriguez Key and cause damage to their property. A petition signed by a large number of Key Largo residents reflects their opposition to Petitioner's use of Rodriguez Key as a primate breeding and research facility. (Testimony of public witnesses (Hearing Officer's Exhibit 2) Exhibits 9-10) There probably would be no odor problem connected with the presence of monkeys on Rodriguez Key if the cages are regularly cleaned and fecal waste is disposed of according to sanitary methods. Although primates are inclined to vocalize at feeding time or when strangers appear, they do not screech at great length and the presence of trees and other foliage would modify the sound. (Testimony of Darrow)
Recommendation That the application of Petitioner Melvin J. Laney, as modified in the above Conclusions of Law, be approved and that a permit authorizing the requested activities be issued pursuant to Chapter 403, F.S., together with water quality certification under PL-500, subject to standard conditions reasonably necessary for prevention of pollution.

The Issue The issue is whether Ponce Marina, Inc., (Ponce Marina) is entitled to a dredge and fill permit and water quality certification number 64-1303059 to construct a marina on the Halifax River in Volusia County, Florida.
Findings Of Fact The Department received an application from Ponce Marina on February 6, 1987, for a permit/water quality certification to construct a 178 slip marina facility consisting of two marina basins and two access channels. The work was to be done in primarily existing uplands adjacent to the Intercoastal Waterway (ICW) within the boundaries of the Town of Ponce Inlet, Volusia County, Florida. In response to agency objections, the scope of the project was reduced to include the excavation of a single marina basin and entrance channel and the construction of a 142 slip marina, by: constructing a basin by excavating 153,000 cu. yds. of material landward of mean high water (MHW) to a maximum depth of -6 feet mean low water (MLW); constructing an entrance channel 200 feet long by 80 feet wide by hydraulically dredging 2,100 cu. yds. waterward of MHW to a maximum depth of -7 feet MLW; connecting the head region of the excavated basin to an existing tidal creek by installing a 60 foot long, 36 inch diameter culvert pipe set at invert -2.0 feet NGVD and fitted with a 36 inch flap gate; installing 1,695 linear feet of vertical bulkhead with a riprap toe, 1,200 linear feet of native rock revetment, 680 linear feet of native rock riprap for use as wave-breaks; constructing 3 main piers, 8 feet in width and 140 feet, 180 feet and 210 feet in length, and 66 finger piers 3 feet in width and 30 feet to 50 feet in length, providing 142 wet boatslips; constructing a stormwater treatment system for the upland development associated with the marina facility; filling a 0.53 acre barrow canal with 4,000 cu. yds. of material; impacting 2.44 acres of jurisdictional wetland area; and creating 2.9 acres of jurisdictional wetland area. The application was filed on behalf of Ponce Marina by Robert M. Snyder, P.E., a professional engineer registered in the State of Florida. On June 20, 1988, the Department issued its Intent to Issue Permit No. 64-1303059 to Ponce Marina. The Intent to Issue contains 21 Specific Conditions the Department will place on the Permit. All conditions are reasonable and necessary. The project site is located on the eastern side of the Halifax River, 3.5 miles south of the Port Orange Causeway and 2.3 miles north of Ponce Inlet in the Town of Ponce Inlet, Volusia County, Section 24, Township 16 South, Range 33 East, not in aquatic preserve, in Class III waters. The project site was formerly salt marsh associated with the Halifax River. The majority of the project site now consists of fill placed on the salt marsh at some time in the past. This fill created an upland strip approximately 500 feet wide and 2,000 feet long. Running through this upland strip is a central ditch which originates at a stormwater sewer on the east side of South Peninsula Drive and runs toward the west to the Halifax River. The proposed marina basin is to be excavated from the upland strip and central ditch described above. The marina design includes the creation of a wetland area in the head region of the basin as well as the connection of the head region to Live Oak Creek, an existing tidal creek, by installing a 60 feet long, 36 inch diameter culvert set at -2.0 feet NGVD and fitted with a 36 inch flap gate. The estuarine marsh wetland to be created at the head of the marina is designed to provide water quality treatment to incoming tides which reach this area. This treated water will then move through the flap gate into Live Oak Creek, where it will receive further treatment before entering the Halifax River. The entrance to the marina will be 180 feet wide. The dredged access channel through that 180 feet entrance, for the navigation of deeper draft boats, will be 80 feet wide by 200 feet long. Construction of the entrance channel will require the excavation of approximately 2,100 cu. yds. of material from the submerged lands of the Halifax River, however, the areas to be dredged consist of unvegetated sand which is not expected to impact marine resources. Excavation of the marina basin will result in 2.44 acres of direct wetland loss. These wetlands are mainly associated with the central ditch. Some marsh north of the upland strip will also be encroached upon. The wetland area eliminated by construction will be replaced by the creation of 2.9 acres of wetland area to be planted with mangroves and smooth cordgrass. It is expected that the created wetland area will provide those same functions as the replaced wetlands within four to five months of planting and will become fully established within two to three years of planting. There is an extremely high success rate for this type of created wetlands within marina basins. The proposed mitigation provides a 1.3:1 ratio of created saltmarsh and mangrove areas and is consistent with Department policy. Diverse shoreline treatments are proposed which will protect wetland and vegetated areas within the marina basin from boat wakes and high energy exchange. This shoreline treatment will include vertical bulkheads, sloping native rock revetments, and submerged wake breaks. There are two or more boat slips directly adjacent to the created wetland on the south side of the basin. Boats in these slips can easily hit the wetlands and damage them. These slips should be eliminated or redesigned to provide protection for these wetlands. The created wetlands are placed so as to provide nursery habitat adjacent to deep water and to filter and treat tidal waters as they move through them. The location and proximity to open water of the created wetlands and the flushing characteristics of the basin will result in higher quality wetlands than those being replaced. The approximately 94 acres of remaining wetlands surrounding the marina project will be placed in a perpetual conservation easement by Ponce Marina. This conservation easement will include two spoil islands to the south of the main upland portion of the property as well as a nonjurisdictional Oak Hammock to the north of the project. The marina, as designed, is a system which is hydraulically driven by the tide. The tide in this region has a mean range of 2.77, that is, a 2.77 feet amplitude change from slack low water to slack high water. In this particular marina system, flushing is driven by two tidal components: (1) a tidal prism which is nothing more than the ratio of the tide volume to the mean low water volume of the basin and, (2) a flow-through component which occurs because there is an elevation difference from one portion of the system to another. A more rigorous flushing action occurs in a flow- through system. The marina is designed with a flap gate so that the facility will have a flow-through potential. Because a flow- through system generates turbulence, it provides mixing through the water column to eliminate or greatly minimize potential for pockets of water that could become stagnant. This is particularly effective in the head regions of the basin. The flap gate operates not only to ensure that water regularly moves out of the head region, but also to ensure that water from the marsh area will not flow into the marina basin, since such water contains organics which could be transported into the marina basin, thereby increasing the potential to violate dissolved oxygen standards. The marina, as designed, will provide a flushing time of 4.6 days for 100 percent flushing, which is adequate to provide reasonable assurance that water quality standards will not be degraded in either the marina basin or adjacent waters. The velocity of water going through the flap gate will not cause erosion. While no operational problems are anticipated with the flap gate, its proper operation is critical to the flushing of the basin. An appropriate design and regular maintenance will be necessary for the flap gate to operate as anticipated. There is no condition in the Intent to Issue which addresses the design and maintenance of the flap gate. Such a condition should be included. The east-west portion of an existing L-shaped canal situated in the northern portion of the property will be filled. The area to be filled is .53 acres. The L-shaped canal is within the Department's jurisdiction, is connected to the Halifax River, and is therefore waters of the State. There is a 36-inch culvert coming from under Peninsula Drive which takes stormwater runoff from an existing condominium development and empties that runoff into the L-shaped canal. Currently, untreated water is coming off impervious surfaces and under the highway by pipe directly into waters of the state, with no detention, no retention, no initial treatment. Therefore, the worst pollutant slug is going directly into waters of the state. This stormwater runoff receives no treatment prior to being directly discharged to waters of the state. Such a system would not be permitted by the Department today. State water quality will be improved by removing the direct stormwater drainage to waters of the state. Ponce Marina has provided an alternate plan for the water which is currently coming from off the project site and discharging through the 36-inch culvert directly into waters of the state. The water is to be routed through a considerable length of grassy ditch behind a weir which will retain the water so that it will receive proper treatment before entering the marsh area. This stormwater will not be routed to a retention area in the oak hammock to the north of the project. The water quality in the remaining portion of the L- shaped canal will not be reduced by the filling of the .53 acre east-west segment, nor is it expected to decline after the filling. The proposed stormwater treatment system for the marina project meets the criteria specified by Florida Administrative Code Chapter 17-25. Further, the stormwater management system for the project was never properly made an issue in this proceeding. The U. S. Fish and Wildlife Service issued a no jeopardy letter to Ponce Marina on July 11, 1988, indicating that the proposed marina will not endanger the manatee or the Atlantic Saltmarsh snake. Those are the only endangered or threatened species that would be expected to be affected by this project. On September 1, 1987, Colonel Robert M. Brantly, Executive Director of the Florida Game and Fresh Water Fish Commission, issued a letter to Secretary Dale Twachtmann recommending, (1) the southern basin of the original marina project be eliminated; (2) the remaining northern basin be designed to lessen wetland impacts, a hydrographic analysis be performed to ensure adequate flushing, there be a DNR determination of no adverse impact to the manatee; and (3) the oak hammock be preserved before issuance of the permit. These recommendations were followed by the Department and are incorporated in the current proposal for the project. On August 21, 1987, the Florida Department of Natural Resources issued its recommendations to the Department concerning the proposed marina, as it relates to the manatee. The recommendations of the DNR are incorporated in permit conditions 16, 17, and 18a through 181. A March 16, 1987, report prepared by staff of the Environmental Control Division of Volusia County recommended approval of the original marina project with three recommendations. Although Volusia County recommended a 90 percent survival rate, an 80 percent survival rate in the mitigation plan is reasonable. Marina plans provide for a sewage pump-out service for boats, as recommended. A condition prohibiting live-aboards on vessels was inadvertently omitted from the condition in the Intent to Issue. The PAC called as its only witness, Dr. Bernard J. Yokel, who was qualified as an expert in estuarine ecology and fisheries. Although Dr. Yokel expressed concern about the removal of a portion of the L-shaped canal and on the introduction of water from the marina into Live Oak Creek, there was no testimony whatsoever that it would be a violation of any criteria of the Department's Class III Water Standards or any other promulgated departmental standard. In fact, Dr. Yokel was unfamiliar with the provisions of Chapters 17- 3 and 17-4, Florida Administrative Code, and was also unfamiliar with the Coastal Marinas Assessment Handbook, the 1985 version published by the Environmental Protection Agency (EPA). Although Dr. Yokel expressed some concern regarding the impact of the marina on the existing linear wetlands in the ditches, he never rendered any opinion as to whether or not reasonable assurances had been provided that the proposed permit was contrary to the public interest, would cause adverse water quality or have adverse effects on fish, shellfish, crabs, and other wildlife. He rendered no opinion as to whether or not the proposed project, if permitted, would adversely affect the conservation of fish and wildlife. The Petitioner, Lawrence Decker, did not testify. He did present Robert Bullard, P.E., as an expert. Mr. Bullard expressed concern about the operation of the flap gate between the marina basin and Live Oak Creek. However, Mr. Bullard expressed no opinion as to whether or not there would be a violation of any criteria contained in Chapters 17-3, 17-4, or 17-25, Florida Administrative Code, or of the Department's Class III Water Quality Standards. The witness, Mr. Bullard, also expressed concern about the hydrographic characteristics of the marina basin and of the L-shaped canal. However, Mr. Bullard never expressed an opinion that the project as designed would degrade State Water Quality Standards below those set in Chapters 17-3, 17-4, and 17-25, Florida Administrative Code, or the Department's Class III Water Quality Standards. Mr. Bullard never expressed any opinion as to whether or not reasonable assurances had been given by the applicant, Ponce Marina, to the Department, that the project would not meet the criteria as provided in Chapter 403, Florida Statutes, or the rules promulgated by the Department thereunder. The applicant, Ponce Marina, has provided reasonable assurances that the project will not violate water quality standards or other standards established pursuant to Chapter 493, Florida Statutes, and Rules 17-3.051, 17- 3.061, and 17-3.121, Florida Administrative Code, relating to Class III waters. The project as designed is not contrary to the public interest. The mitigation more than offsets the wetlands lost. There is evidence to establish that the project, with mitigation, will not adversely affect the public health, safety, welfare, or property of others; nor adversely affect the conservation of fish and wildlife, including endangered or threatened species or their habitats; nor adversely affect navigation or flow of water or cause harmful erosion or shoaling; nor adversely affect the fishing or recreational value or marine productivity in its vicinity; nor adversely affect significant historical or archaeological resource.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Regulation enter a Final Order and therein grant permit number 64-1303059 to Ponce Marina, Inc., with three additional specific conditions added to the twenty-one conditions set forth in the Intent to Issue: No live-aboard vessels are to be allowed at the marina. The applicant shall design and shall provide regular maintenance for the flap gate so as to insure that the flap gate will perform as required as an integral and critical component of the flushing design of the marina basin. The applicant shall eliminate or redesign the boat slips directly abutting the created wetlands on the south side of the basin, so as to protect those wetlands from damage.

The Issue The issue is whether Respondent Koreshan Unity Foundation, Inc., is entitled to a environmental resource permit for the construction of a wooden footbridge over the Estero River east of U.S. Route 41 and authorization to obtain by easement a right to use sovereign submerged lands.
Findings Of Fact Respondent Koreshan Unity Foundation, Inc. (Koreshan) is a not-for-profit corporation dedicated to the preservation of the Koreshan heritage. Koreshan derives its heritage from a largely self-sufficient community that occupied land in south Lee County. For several years, Koreshan has owned a parcel of 14.56 acres at the southeast corner of U.S. Route 41 and the Estero River. This parcel is bounded on the south by Corkscrew Road and contains an amphitheater and historical house, midway between the river and Corkscrew Road. The south end of this parcel contains a museum and parking area with access to Corkscrew Road. The approximate dimensions of the 14.56-acre parcel are 544 feet along the river, 496 feet along Corkscrew Road, and about 1273 feet along the west and the east property lines. The west property line is U.S. Route 41. The right-of-way for U.S. Route 41 is wider at the southern two-thirds of the parcel than the northern one-third of the parcel. A sidewalk runs on the east side of U.S. Route 41 from north of the river, across the U.S. Route 41 bridge, along the west boundary of Koreshan's property, at least to an entrance near the middle of the 14.56-acre parcel. In October 1996, Koreshan acquired 8.5 acres of land at the northeast corner of the U.S. Route 41 and the river. The purpose of the acquisition was to provide parking for persons coming to Koreshan-sponsored events, such as music performances, at the 14.56-acre site. Koreshan rents a small portion of this northerly parcel to a canoe-rental business, which operates where the bridge and river meet. To assist their visitors-some of whom are elderly and disabled--in gaining access to the 14.56-acre site, on November 26, 1996, Koreshan filed an application for a permit and authorization to construct a wooden footbridge across the Estero River about 315 feet east of the U.S. Route 41 bridge. The source of the Estero River is to the east of the U.S. Route 41 bridge and the location of the proposed bridge. After passing under the U.S. Route 41 bridge, the river runs along the Koreshan state park, which is a short distance east of U.S. Route 41, before it empties into the Gulf of Mexico at Estero Bay, which is a state aquatic preserve. The portion of the river at the site of the proposed bridge is an Outstanding Florida Waterway (OFW) and a Class III water. The river is popular with canoeists and kayakers. Persons may rent canoes and kayaks at the canoe rental business operating on the 8.5-acre parcel or the Koreshan state park. Although most canoeists and kayakers proceed downstream toward the bay, a significant number go upstream past the U.S. Route 41 bridge. Upstream of the bridge, the river narrows considerably. Tidal currents reach upstream of the U.S. Route 41 bridge. At certain tides or in strong winds, navigating a canoe or kayak in this area of the river can be moderately difficult. Even experienced canoeists or kayakers may have trouble maintaining a steady course in this part of the river. Less experienced canoeists or kayakers more often have trouble staying on course and avoiding other boats, the shore, vegetation extending from the water or shoreline, or even the relatively widely spaced supports of the U.S. Route 41 bridge pilings, which are about 30 feet apart. Mean high water is at 1.11 feet National Geodetic Vertical Datum. The deck of the proposed footbridge would be 9 feet, 6 inches wide from rail to rail and 16 feet wide in total. The proposed footbridge would extend about 180 feet, spanning 84 feet of water from shore to shore. The bridge- ends would each be about 50 feet and would each slope at a rate of 1:12. The proposed footbridge would rest on nine pilings: four in the uplands and five in the submerged bottom. The elevation of the bottom of the footbridge from the water surface, at mean high water, would be 8 feet, 8 inches. The distance between the centers of the pilings would be 14 feet, and each piling would be of a minimum diameter of 8 inches. According to a special permit condition, the pilings would be treated with chromated copper arsenate, as a preservative, but they would be wrapped in impermeable plastic or PVC sleeves so as, in the words of the proposed permit, "to reduce the leaching of deleterious substances from the pilings." The proposed permit requires that the sleeves shall be installed from at least 6 inches below the level of the substrate to at least 1 foot above the seasonal highwater line and shall be maintained over the life of the facility. The proposed permit also requires that the footbridge be limited to pedestrian traffic only, except for wheelchairs. The permit requires the applicant to install concrete-filled steel posts adjacent to the bridge to prevent vehicles from using the bridge. The proposed permit requires that Koreshan grant a conservation easement for the entire riverbank running along both shorelines of Koreshan's two parcels, except for the dock and boat ramp used by the canoe-rental business. The proposed permit also requires Koreshan to plant leather fern or other wetland species on three-foot centers along the river banks along both banks for a distance of 30 feet. The proposed permit states that the project shall comply with all applicable water quality standards, including the antidegradation permitting requirements of Rule 62-4.242, Florida Administrative Code. Respondents did not raise standing as an affirmative defense. It appears that Petitioners or, in the case of corporate Petitioners, members and officers all live in the area of the Estero River and use the river regularly. For instance, Petitioner Dorothy McNeill resides one mile south of the proposed bridge on a canal leading to the Estero River, which she uses frequently. She is the president and treasurer of Petitioner Estero Conservancy, whose mission is to preserve the Estero River in its natural state. Petitioner Ellen W. Peterson resides on Corkscrew Road, 300-400 feet from the proposed footbridge. For 26 years, she has paddled the river several times weekly, usually upstream because it is prettier. She formerly canoed, but now kayaks. The record is devoid of evidence of the water- quality criteria for the Estero River at the time of its designation as an OFW or 1995, which is the year prior to the subject application. Koreshan has not provided reasonable assurance that the proposed footbridge would not adversely affect the water quality of the Estero River. Although the site of the proposed footbridge is devoid of bottom vegetation and there is no suggestion that this is anything but a natural condition for this part of the riverbottom, there is evidence that the proposed footbridge would adversely affect the water quality in two respects: turbidity caused by the pilings and leaching from the chromated copper arsenate applied to the pilings. The turbidity is probably the greater threat to water quality because it would be a permanent factor commencing with the completion of the installation of the pilings. The leaching of the heavy metals forming the toxic preservative impregnated into the pilings is probable due to two factors: damage to the PVC liner from collisions with inexperienced boaters and high-water conditions that exceed 1 foot over mean high water and, thus, the top of the liner. Both of these factors are exacerbated by flooding, which is addressed below. Koreshan also has failed to provide reasonable assurance that the proposed footbridge is clearly in the public interest under the seven criteria. The proposed footbridge would adversely affect the public health, safety, or welfare and the property of others through exacerbated flooding. South Lee County experienced serious flooding in 1995. In response, Lee County and the South Florida Water Management District have attempted to improve the capacity of natural flowways, in part by clearing rivers of snags and other impediments to flow, including, in the case of the Imperial River, a bridge. One important experience learned from the 1995 floods was to eliminate, where possible, structures in the river, such as snags and pilings, that collect debris in floodwaters and thereby decrease the drainage capacity of the waterway when drainage capacity is most needed. Longer term, the South Florida Water Management District is considering means by which to redirect stormwater from the Imperial River drainage to the Estero River drainage. The addition of five pilings (more as the river rose) would exacerbate flooding. On this basis alone, Koreshan has failed to provide reasonable assurance. Additionally, though, the HEC II model output offered by Koreshan does not consider flooding based on out-of-banks flows, but only on the basis of roadway flows. In other words, any assurances as to flooding in the design storm are assurances only that U.S. Route 41 will not be flooded, not that the lower surrounding land will not be flooded. Koreshan failed to provide reasonable assurance that the proposed activity would not adversely affect the conservation of fish and wildlife, for the reasons already stated with respect to water quality. Koreshan failed to provide reasonable assurance that the proposed activity would not adversely affect navigation or the flow of water. The flow of water is addressed above. Navigation is best addressed together with the next criterion: whether the proposed activity would adversely affect fishing or recreational values or marine productivity in the vicinity of the activity. Despite the presence of only two public launch sites, boating is popular on the Estero River. Reflective of the population growth of Collier County to the south and the area of Lee County to the north, the number of boaters on the Estero River has grown steadily over the years. The canoe- rental business located on the 8.5-acre parcel rented canoes or kayaks to over 10,000 persons in 1996. Many other persons launched their canoes or kayaks for free from this site and the nearby state park. Lee County businesses derive $800,000,000 annually from tourism with ecotourism a growing component of this industry. The Estero River is an important feature of this industry, and the aquatic preserve at the mouth of the river and the state park just downstream from the proposed footbridge provide substantial protection to the scenic and environmental values that drive recreational interest in the river. It is unnecessary to consider the aesthetic effect of a footbridge spanning one of the more attractive segments of the Estero River. The proposed footbridge and its five pilings effectively divide the river into six segments of no more than 14 feet each. This fact alone diminishes the recreational value of the river for the many canoeists and kayakers who cannot reliably navigate the U.S. Route 41 bridge pilings, which are more than twice as far apart. As to the remaining criteria, the proposed footbridge would be permanent and the condition and relative value of functions being performed by areas affected by the proposed activity is high. There is conflicting evidence as to whether the proposed footbridge would adversely affect the remnants of an historic dock, but it is unnecessary to resolve this conflict. The mitigation proposed by Koreshan does not address the deficiencies inherent in the proposed activity.
Recommendation It is RECOMMENDED that the Department of Environmental Protection enter a final order dismissing the petition of Petitioner Council of Civic Associations, Inc., and denying the application of Respondent Koreshan Unity Foundation, Inc., for an environmental resource permit and authorization to obtain an easement for the use of sovereign land.

Findings Of Fact The Petitioner owns property which is adjacent to Lake Serena in Putnam County, Florida. Through his application to the Respondent, the Petitioner is seeking to dredge an area waterward of the ordinary high water line of Lake Serena, and to place the dredged material on another area waterward of the ordinary high water line. The purpose of the proposed dredging and filling is to create a more gradual shoreline sloping from the Petitioner's residence to the shore of Lake Serena. Petitioner proposes to cover the filled area with white sand. He proposes to use the area as a sandy swimming beach. The area which the Petitioner is proposing to dredge and fill is presently dominated by wetlands vegetation, which would be removed by the dredging activity. The Petitioner originally commenced his project without receiving any permit from the Respondent. A large amount of the wetlands vegetation has already been removed. Lake Serena is a relatively pollution-free lake. Much of the littoral or transitional zone vegetation surrounding the lake has been replaced by sandy swimming beaches. Only approximately forty percent of the shoreline is now an aquatic vegetated littoral zone. Aquatic vegetation in the littoral zone surrounding Lake Serena serves an important natural function in preserving the water quality in the lake, and in preserving the natural resources of the lake, including fish and wildlife. The aquatic vegetation serves to filter run-off from uplands areas by assimilating nutrients that are in the run-off. A nutrient scale has been devised for identifying the amount of nutrients in a lake. An oligotrophic lake is low in nutrients. A mezotrophic lake has a moderate amount of nutrients. A eutrophic lake is high in nutrients. In the natural process of aging, water bodies progress from oligotrophic to a eutrophic state. This is a very long natural process taking thousands of years. Lake Serena is an oligotrophic lake. Aquatic vegetation in the littoral zone surrounding Lake Serena serves to maintain this condition. If too much aquatic vegetation is removed from the littoral zone, a buildup of nutrients would result. This buildup of nutrients would cause an algal bloom, or a buildup of algae plants on top of the lake. A buildup of algae on the lake would drastically decrease the oxygen level of the lake. This is because algae itself uses oxygen, because algae kills oxygen producing plants which thrive on the bottom of the lake due to light being cut off, and because, as the algae dies, it sinks and decomposes using up more oxygen. An algal bloom, and the resulting reduction of oxygen levels in a lake would constitute pollution. Removal of aquatic plants in Lake Serena's littoral zone would serve to diminish fish and wildlife populations in the lake. Small fish use such an area as a nursery ground where they can hide from predators. Without such a nursery ground, the cycle of survival for aquatic wildlife would be cut off. The area from which the Petitioner has already removed considerable wetlands vegetation, and proposes to remove more, is a viable part of the littoral zone of Lake Serena. The area serves the beneficial purposes set out in Paragraph 2 above. It cannot be determined with any degree of certainty that the Petitioner's proposed project would have any finitely measurable impact upon water quality or wildlife resources in Lake Serena. Certainly removal of all such littoral zones would drastically change the ecology of the lake and render it polluted. Sixty percent of Lake Serena's shoreline has already been denuded of vegetation. Although it cannot be determined precisely how much more such action the lake will tolerate, it is clear that there is a limit. If the Petitioner's project were granted, other similar projects would also be justified. Inevitably the lake's oligotrophic nature would be destroyed. The only effect that the Petitioner's project could have upon the water quality and natural resources of Lake Serene is negative. No evidence was offered at the hearing from which it could be determined that the Petitioner's proposed project would not have an adverse impact upon the water quality and natural resources of Lake Serene. In its notice of intent to deny, Respondent asserted that the proposed project would be expected to degrade the water quality of Lake Serena, and to violate water quality standards because turbidity levels would exceed permissible limits. Respondent is contending that during the pendency of the project turbidity levels will be too high. At the present time the water level of Lake Serena is two to three feet below the ordinary high water line. The area Petitioner proposes to dredge and the area he proposes to fill, while below the ordinary high water line, are above the present water line. From the evidence it appears that steps could be taken so that the proposed project could be accomplished without exceeding permissible turbidity levels. The only purpose that would be served by the Petitioner's proposed project is to provide Petitioner with a sandy swimming beach rather than a natural shoreline.
Findings Of Fact By Joint Application for Works in the Waters of Florida filed June 22, 1994, Petitioner requested a permit to dredge about 500 square feet of uplands for a boatslip and to maintenance dredge 1700-1900 square feet in an adjacent canal, removing 125 cubic yards of material waterward of mean high water. The Application describes the work as including a vertical concrete seawall running 92 feet inside the boatslip, a cat walk from the boatslip to the canal, and a roof over the boatslip. A drawing attached to the Application depicts the proposed boatslip at the east end of the Petitioner's lot and with rounded corners to facilitate flushing. By Notice of Permit Denial executed October 24, 1994, Respondent advised that the permit was denied. The Notice states that water quality in the surrounding canal system is generally poor with low dissolved oxygen (DO) levels. The shoreline vegetation is primarily mangroves, which are tall but not robust. The proposed dredge area consists of a healthy littoral shelf with live oysters and shells. Based on the foregoing site description, the Notice denies the permit because of impacts to the conservation of fish and wildlife and marine productivity and a degradation of the current condition and relative value of the affected area. The Notice relates all of these factors to the loss of the mangroves and dredging of the adjacent canal bottom. The Notice adds that the project would have an adverse cumulative impact on water quality and public resources if similar projects were constructed. In the alternative, the Notice suggests that Petitioner eliminate the dredging into the uplands and canal and instead construct a boat shelter in the canal in an area of existing adequate water depth. By letter dated November 7, 1994, Petitioner challenged the denial. The letter states that Petitioner has maintained an environmentally productive shoreline consisting of mangroves, oysters, and rip rap, rather than concrete seawalls, as are found along the shoreline of most of his neighbors. The letter suggests that, if Petitioner followed Respondent's suggestion and built a slip in the canal, Petitioner would be permitted to do maintenance dredging in the artificial canal. The letter concludes that the maintenance dredging and shading of an over- the-water boathouse would have more impact on the environment than dredging uplands and a small access channel to the slip. Petitioner's residence is located in Aqualane Shores, which is an established residential subdivision located between Naples Bay on the east and the Gulf of Mexico on the west. Petitioner's lot is located about two-thirds of the distance down a long, relatively wide artificial canal known as Jamaica Channel. Jamaica Channel intersects Naples Bay to the east of Petitioner's property. Jamaica Channel is a Class III waterbody. Petitioner owns about 200 feet of shoreline at the corner of Jamaica Channel and a shorter, narrower canal. The entire area is heavily canalized and completely built-out with nearly exclusively single family residences. Most of the shoreline in the area is bulkheaded with concrete seawalls. Jamaica Channel was dredged in the early 1950s. Early riprap revetment crumbled into the water and in some areas became colonized by oysters, which supply food and filter impurities from water. Shoreline owners weary of repairing riprap installed vertical seawalls, thereby destroying the oyster beds and intertidal habitat. But much of the riprap adjacent to unbulkheaded shoreline eventually was stabilized by mangrove roots. The absence of concrete seawalls along Petitioner's shoreline has permitted a significant colony of oysters to populate the 25-foot littoral shelf running along Petitioner's shoreline. The oysters form a hemisphere, thickest at the middle of Petitioner's shoreline and narrowest at the east and west edges, narrowing to a width of as little as 6-10 feet. In recent years, Australian pines were removed from Petitioner's shoreline. As a result, mangrove seedlings have successfully occupied much of the shoreline. The proposed boatslip would be located at the east end of the shoreline where there is a natural gap in the mangroves. As a result, only three mangroves would have to be removed, and a relatively narrow band of oysters would be dredged and, as offered by Petitioner, relocated. The proposed dredging involves uplands and submerged bottom. As to the uplands, Petitioner intends to create a slope in the slip with the rear one to one and one-half feet shallower than the front, although this slope is not reflected on the Application. The purpose of the slope is to facilitate flushing. Petitioner evidently intends to dredge sufficient material to fill the rear of the slip with two feet of water at mean water and the front of the slip with three feet of water at mean water. The dredging in Jamaica Channel would involve an 18-20 foot wide path leading to the slip. Beyond the oysters, the bottom is fine sandy substrate with scattered rock. The relocation of oyster-covered rocks might be successful, if there are sufficient areas suitable for colonization that have not already been colonized. However, the dredged areas would not be recolonized due to their depths. Presently, the Application discloses level dredging down to an elevation of -5 NGVD. Petitioner's intent to slope the boatslip has been discussed above. Although Petitioner did not reveal a similar intent to slope the area dredged in Jamaica Channel, Petitioner's witness, Naples' Natural Resource Manager, testified that he would insist on similar sloping the entire length of the dredged area, so that the deepest area would be most waterward of the boatslip. If the dredged canal bottom were not sloped, Petitioner proposes removing about 4.25 feet of material about ten feet from shore, about 3.4 feet of material about 22 feet from shore, about 1.8 feet of material about 30 feet from shore, and about 0.5 feet of material about 40 feet from shore. Petitioner did reveal that the cross-section indicating a dredged depth of -5 feet applies only to the centerline of the dredge site, which would be tapered off to the east and west. The slope of the taper was not disclosed, but it is evident that the affected areas within 20 feet of the shoreline would be dredged at least two feet deeper and, in most areas, three feet deeper. The deepening of Jamaica Canal in the vicinity of the shoreline would not only eliminate existing oyster habitat, but would also eliminate habitat currently used by small fish. The deepening of Jamaica Channel in the vicinity of the shoreline would also impact water quality in the area. Water quality in Naples Bay and Jamaica Channel is poor and violates water quality standards for DO. Due to poor mixing of freshwater infusions and saltwater, DO levels deteriorate with depth. Where DO levels are probably adequate in the shallows around Petitioner's shoreline, the proposed dredging would likely result in depths at which violations could be expected to occur. Petitioner offers to install an aerator to introduce oxygen into the water. Ignoring the fact that the aerator was to operate only in the boatslip and not in the remainder of the dredged area, Petitioner did not show the effect on DO levels of this proposal. Even if the aerator had been shown to result in a net improvement in area DO levels, Petitioner also failed to show how the operation of the aerator would be guaranteed to extend indefinitely, or at least until the dredged areas were permitted to regain their pre-dredged depths. Petitioner argues that he could construct an over-the- water boathouse and maintenance dredge, and the resulting environmental impact would be greater. Several factors militate against this proposed alternative and thus preclude consideration of this alternative against the proposed project. Most significantly, the oysters have occupied the littoral shelf adjacent to Petitioner's shoreline for a period in excess of 20 years. There is considerable doubt as to whether Petitioner would be permitted to maintenance dredge under these and other circumstances. Respondent argues more persuasively the issue of cumulative impacts. There are about 350 residences in Aqualane Shores, of which only 150 have boatslips similar to that proposed by Petitioner. This raises the prospect of an additional 200 boatslips as a cumulative impact on water and biological resources.
