The Issue Whether the proposed project will cause or contribute to violations of applicable state water quality standards contained in Rule 17-3, Florida Administrative Code. Whether the public interest criteria of Section 403.918, Florida Statutes will be et. Whether the Respondent DER should grant the applicant RONTO a dredge and fill permit pursuant to the Notice of Intent dated February 8, 1988, in DER File No. 111353525.
Findings Of Fact The Respondent RONTO is the owner and developer of real property contiguous to state waters in Collier Bay at Marco Island, Collier County, Florida. The proposed project is a 4,704 square foot multifamily dock with thirty-eight boat slips. Most of the slips are designed for small boats that are 22 feet or less in length. Three slips are designed to allow the mooring of boats 35 feet or greater in length. This dock is planned to be a private facility which will be used for dockage only. The proposed dock is subject to the Respondent DERs permitting requirements because the construction activity is to take place in Collier Bay (Class II Waters) and the dock structure exceeds 1,000 square feet in size. There is no dredging associated with the project. The facility will extend into the bay from a canal which is directly connected to a deep water channel. A large portion of the dock will be outside of the canal, and the slips provided for larger boats will be located on the south side of the dock in the deeper water. Because the bay is a relatively shallow water body with a number of sand bars, the north side of the dock is designed to accommodate smaller boats which have less draft. The Petitioner is the owner of a single family home within the development which is adjacent to the proposed dock. All that is separating the Petitioner's backyard from the dock site is the canal. This canal is one hundred feet wide. The Petitioner filed a petition in which he disputed the appropriateness of the Intent to Issue filed February 8, 1988. In support of his position, the Petitioner identified a number of areas of controversy which he contends should cause the Respondent DER to reverse its preliminary decision to grant the dredge and fill permit on this project. Water Quality During the application process for the permit, the Respondent DER required water quality sampling done in the bay. Respondent DER designated three general locations from which the samples should be taken. One sample was requested from the mouth of Collier Bay as a control site. The next sample was to be taken from the mouth of the canal, and the third was to be obtained from the water directly under the proposed docks. The samples were collected by the Big Cypress Service Company and sent to an independent, state certified laboratory for analysis. The analysis revealed extremely high levels of lead, cadmium, and zinc in the sediments at all three sampling locations. All three samples exceeded the guidelines established by the Respondent DER's chemistry department to indicate potential water quality problems. In order to determine if sampling error had occurred, a second set of samples was requested by the Respondent DER. This set of samples was gathered by the Big Cypress Service Company in essentially the same locations as the first set. It was sent to a different state certified laboratory for analysis. The results of the analysis of the second set of samples did not show any elevated levels of metals. The first set of samples was considered to be inaccurate by DER because the reported concentrations of metals were not compatible with the project site. There were no indications that a toxic metal dump site which could logically cause such concentrations of metal to occur was located in the area. Even if some toxic metal dumping had occurred in the area, the control sample taken from the mouth of the bay should have revealed lower levels of the metals in its contents due to the flushing activity that occurs there. Because of the factual and logical inconsistencies, DER concluded that an error was made in the gathering of the first set of samples or in the laboratory analysis of them. The results of the analysis of the second set of samples met state water quality standards. They were accepted by DER as accurate and reflective of site conditions. The laboratory analysis of the second set of samples demonstrates that Collier Bay currently meets the criteria for surface waters and the more stringent standards placed upon Class II Waters. During the hearing, the Petitioner did not submit any contrary, reliable evidence based on objective or empirical information which was sufficient to rebut the prima facie showing that the second set of samples accurately reflects the water conditions at the construction site. Water Depths and Water Habitats There are sufficient water depths, based upon the Bathymetric profile and the appraisal and site inspection by the Respondent DER, for a dock to be built at the proposed site. The Bathymetric profile submitted into evidence was completed in June of 1988, prior to the administrative hearing. Although there were photographs and testimony presented which show that a sand bar exists at the mouth of the canal, the Bathymetric profile is found to be determinative of water depths at the site because of its recent compilation and because seasonal fluctuations in water levels cause photographs and testimony to be less reliable. Sea grasses create a positive habitat for the development of animal and fish wildlife. They promote sediment stabilization and provide a pollution filtration system. The placement of the dock at the proposed site will adversely impact upon the development of sea grasses in the canal and the shallow waters to the north and the northeast of the project. Fish, Fowl and Animal Wildlife There was insufficient evidence presented to establish that the local bird and fish habitats will be adversely impacted by the proposed dock. There was no evidence that the dock site is a bird roosting area, although an eagle has fished at that location on a regular basis. Bird life such as the ospreys in the area will be unaffected by human disturbances. Manatees have been regularly sighted in the Collier Bay area in large numbers. The evidence as to potential harm to this endangered species from the building of the proposed dock is inconclusive. Navigation The proposed dock will increase boat traffic in the bay. Due to the location, boats seeking to leave the dock to go to the river will speed across the shallow area to the north and northeast of the dock. Higher speeds are necessary to create a shallow draft to prevent the boats from running aground. There is no competent evidence to show that this activity will increase boating dangers within the bay. The proposed new channel from the dock to the existing channel on the eastern side of the bay will not create a new navigational hazard. Speeding boats from the south will have a clear view of the boats in the new channel for an extended period of time before they actually meet in the channel intersection. Mitigation In order to mitigate the possibility of the project having an adverse impact on the water quality, the Respondent RONTO proposed certain measures it would take to improve water quality at the site. The application for the permit was amended to include the following: "A riprap/mangrove area will be created between the existing seawall and the proposed docks. Monitoring and remedial actions will be performed to assure an 80 percent survival of the red mangroves." In order to create the riprap/mangrove area, the dock was redesigned to be placed several feet away from the seawall. It is anticipated that this small restoration program will promote sediment stabilization. This stabilization will become important when the project is completed because waste or debris resulting from the increased boat traffic will be expected to settle at the bottom of the canal and accumulate in sediments. The program will assist in keeping the sediments down in the canal bottoms. During the construction of the project, the placing of the pilings will cause turbidity which will affect the water quality standards on a short- term basis. In order to mitigate the temporary damage from pile placement, the Respondent RONTO will use turbidity screens to contain all generated turbidity. The riprap and the mangroves will assist in the functions of the biological systems at the site. As stated previously, the project will affect the sea grasses in the canal as well as those to the north and northeast of the project. The new positive habitat which will be created at the site will provide a more effective pollution filtration system than the one currently provided by the sea grasses. Because of the depth of the canal, and the inability of the sea grasses to attach and grow well around the site, the current conditions within the canal are unstable. The restoration program will be more stable than the sea grasses because of the nature of the program and because the Respondent RONTO will warrant the survival of eighty percent of the red mangroves for the life of the permit. The mangroves will also provide for the uptake of nutrients in the water column. This will help to support the development of marine life at the site. It is anticipated that there will be additional attachment opportunities and greater protection for the young marine life. The primary production of fish and wildlife species will be enhanced by the restoration program. Mangroves provide a habitat for approximately ninety per cent of the commercially valuable fish and shellfish species in the area. The riprap will provide a habitat for oysters, barnacles, and other marine organisms. As a result, there should be an increase in crabs and other marine life in the area. The Respondent RONTO has been required by the Respondent DER to space the deck planks at least three-eighths of an inch apart in order to allow for additional penetration of light through the planks. This will allow for photosynthesis to occur in plant life in the water. Plant production is encouraged in order to help maintain the adequate levels of dissolved oxygen for the Class II Waters in the canal area. Also, because of ecological development, the production of primary plant life provides the opportunity for additional marine life in the area. The riprap will stabilize the slope at the base of the seawall. This will prevent erosion in that area. To safeguard against injury or death to manatees in the bay area from the increase in boats, particularly boats which may be speeding to reach the river through the shallow areas, the Respondent RONTO has volunteered to place an educational display on the upland. This display will notify the boaters using the facility that manatees frequent the area. It will give them information about their habits and practices. In addition, the Respondent DER and the Department of Natural Resources are requiring the installation of manatee caution signs at the dock and in the access channels in Collier Bay. The entire bay is designated as an idle speed zone. There are numerous "no wake" and "idle speed" signs in the bay. If the boaters obey the boating rules and regulations within the bay and remain on the lookout for manatees as required, the addition of the thirty eight boat slips should have a minimal adverse impact on the manatee population. In order to mitigate the potential navigational problems the additional boats could cause in the bay, the Respondent DER has required the Respondent RONTO to clearly mark the proposed navigational channel from the docks to marker six in the existing channel with U.S. Coast Guard approved markers. These markers will be spaced one hundred feet apart. The marking of this new channel should eliminate some of the current navigational problems in the bay. The markers, by their location, will discourage boaters from entering the shallow areas north of the proposed docks. Balancing of Interests In the dredge and fill application appraisal, site review, and notice of intent to issue, the Respondent DER considered and balanced all of the required statutory criteria to determine that the project is not contrary to the public interest or applicable water quality standards. Areas of Controversy All of the areas of controversy raised by the Petitioner which are within the Division of Administrative Hearings' jurisdiction have been sufficiently met by the reasonable assurances of Respondent RONTO and the permit conditions required by Respondent DER. Based upon the evidence presented, it is concluded that the harms anticipated by the Petitioner will not occur.
The Issue The issue here presented concerns the entitlement of the Applicant/Respondent, Walker G. Miller, to construct an addition to his existing boat house of approximately 450 square feet, and an addition to his existing chain link fence, both of which are located on Lake Down, Florida. The Respondent, Department of Environmental Regulation, has indicated its intention to grant the permit application request and the Petitioners, Milton and Gail Hess, and David Storey and others, have opposed the Department's intention to grant the permit.
Findings Of Fact The Petitioner in Case No. 80-1769, Milton Hess, is an adjacent landowner to the Applicant/Respondent, Walker G. Miller, with property located on Lake Down, near Windermere, in Orange County, Florida. The Petitioners in Case No. 80-1770, David Storey and others, are also landowners on Lake Down. Applicant's parcel is located on Down Point, which is a peninsular extending from the Lakes's southern shore. The project as contemplated by the Applicant is the construction of a 15 foot by 30 foot unenclosed addition on the north side of an existing dock/boathouse combination located on Lake Down. The 450 square foot addition is to be utilized as a storage room adjacent to the boathouse portion of his existing structure. The present structure has a total surface area of approximately 825 square feet. Additionally, by amendment to the application made on August 13, 1980, Applicant proposes to construct a chain link fence from the south property line to the dock facility. Lake Down is one of the waterbodies that constitutes the Butler Chain- of Lakes. The Lake is characterized by outstanding water quality and diversified biological resources. The Chain-of Lakes is widely recognized as the outstanding aquatic resource in the State, as far as water quality is concerned. Development on Lake Down is light, with widely scattered residential units separated by expanses of citrus groves. The construction of the addition will not significantly impact Lake Down or the Butler Chain-of Lakes, either on a long-term or short-term basis. The shading effect of the structure will result in a slight decline of rooted aguatic vegetation. However, such decline should be minimal. Further, reasonable assurances have been given that the proposed project would not result in any violations of State water quality criteria or standards. The existing dock structure now obstructs a portion of the view of the lake enjoyed by Petitioner Hess. However, by constructing the proposed addition on the north side of the existing boathouse, no further impediment of the view will occur.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a permit be granted by the Department of Environmental Regulation to Walker G. Miller to construct an addition to his boathouse and a chain link Fence on Lake Down as more specifically described in his amended application.

Findings Of Fact At all times to the issues herein the Department of Environmental Protection was the state agency in Florida responsible for the regulation of water pollution and the issuance of dredge and fill permits in the specified waters of this state. Mr. Byrd has been a resident of the City of Treasure Island, Florida for many years and resides at 123 123rd Avenue in that city. His property is located on Boca Ciega Bay next to a public boat ramp operated by the City. On April 12, 1995, the City of Treasure Island applied to the Department of Environmental Protection for a permit to construct a dock six feet wide by seventy-five feet long, located on the edge of its property on which the public boat ramp is located. This property is located in a basin off Boca Ciega Bay, which is classified as a Class III Outstanding Florida Water. The dock involves the placement of pilings in the water, and the construction of a walkway thereon. In order to be obtain a permit, the applicant must provide the Department with reasonable assurances that the proposed project will not degrade water quality and will be in the public interest. The project is permanent in nature, but the temporary concerns raised by construction have been properly addressed in the permit. In the instant case, the dock is intended to accommodate the boating public which will utilize it to more safely launch, board, debark, and recover small boats at the ramp in issue. The dock will be equipped with a hand rail which will increase the safety of the project. Evidence establishes that without the dock, boaters have to enter the water to launch and recover their boats on a ramp can be slippery and dangerous. The site currently in use as a boat ramp, a part of which will be used for the dock, is almost totally free of any wildlife. No evidence could be seen of any sea grasses or marine life such as oysters, and there was no indication the proposed site is a marine habitat. Manatees do periodically inhabit the area, and warning signs would be required to require construction be stopped when manatee are in the area. The water depth in the immediate area and the width of the waterway is such that navigation would not be adversely impacted by the dock construction, nor is there any indication that water flow would be impeded. No adverse effect to significant historical or archaeological resources would occur and taken together, it is found that the applicant has provided reasonable assurances that the project is within the public interest. Concerning the issue of water quality, the applicant has proposed the use of turbidity curtains during construction which would provide reasonable assurances that water quality would not be degraded by or during construction. The water depths in the area are such that propeller dredging and turbidity associated therewith should not be a problem. No evidence was presented or, apparently is on file, to indicate any documented water quality violations at the site, and it is unlikely that water quality standards will be violated by the construction and operation of the structure. The best evidence available indicates there would be no significant cumulative impacts from this project. Impacts from presently existing similar projects and projects reasonably expected in the future, do not, when combined with the instant project, raise the possibility of adverse cumulative degradation of water quality or other factors of concern. By the same token, it is found that secondary impacts resulting from the construction of the project would be minimal. It is also found that this project is eligible for an exemption from the requirements to obtain a permit because of the Department's implementation on October 3, 1995 of new rules relating to environmental resources. However, the City has agreed to follow through with the permitting process notwithstanding the exemption and to accept the permit including all included conditions. This affords far more protection to the environment than would be provided if the conditions to the permit, now applicable to this project, were avoided under a reliance on the exemption to which the City is entitled under current rules. To be sure, evidence presented by Mr. Byrd clearly establishes the operation of the existing boat ramp creates noise, fumes, diminished water conditions and an atmosphere which is annoying, discomfiting, and unpleasant to him and to some of his neighbors who experience the same conditions. Many of the people using the facility openly use foul language and demonstrate a total lack of respect for others. Many of these people also show no respect for the property of others by parking on private property and contaminating the surrounding area with trash and other discardables. It may well be that the presently existing conditions so described were not contemplated when the ramp was built some twenty years ago. An increase in population using water craft, and the development and proliferation of alternative watercraft, such as the personal watercraft, (Ski-Doo), as well as an apparent decline in personal relations skills have magnified the noise and the problem of fumes and considerably. It is not likely, however, that these conditions, most of which do not relate to water quality standards and the other pertinent considerations involved here, will be increased or affected in any way by the construction of the dock in issue.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: RECOMMENDED that the Department of Environmental Protection issue to the city the requested permit to construct the dock in issue at the existing public boat ramp at the east end of 123rd Avenue right of way in the City of Treasure Island. RECOMMENDED this 12th day of December, 1995, in Tallahassee, Florida. ARNOLD H.

The Issue Whether Southern Hy Power Corporation (Hy Power) has provided reasonable assurance, based on plans, test results, or other information, that its proposed hydroelectric facility will comply with the Management and Storage of Surface Water (MSSW) statutes and rules of Southwest Florida Water Management District (SWFWMD) and the Wetland Resource Management permit (WRM)/water quality certification statutes and rules of the Florida Department of Environmental Protection (DEP).
Findings Of Fact By Joint Prehearing Stipulation the parties agreed to the following description of the parties and the project: PARTIES: The Department of Environmental Protection (the Department) is a government agency in the State of Florida existing by virtue of Section 20.255, Florida Statutes, and operating pursuant to Chapters 253, 373, 376, and 403, Florida Statutes, and Title 62, Florida Administrative Code. Under an interagency agreement with SWFWMD, the Department also implements Title 40D, Florida Administrative Code. The Department is located in Tallahassee, Florida, and it has a district office in Tampa, Florida, which district includes Levy County. Southern Hy Power Corporation is a Florida Corporation whose principal offices are located at 7008 Southwest 30th Way in Gainesville, Florida. Betty Berger is an interested party with a mailing address of Post Office Box 83, Inglis, Florida. The Campbells are an interested party with a mailing address of 245 Palm Street, Inglis, Florida. Hy Power applied on August 31, 1993, to the Department for a WRM permit/water quality certification to construct a hydroelectric facility on the Inglis By-Pass Channel. The project is located in Section 12, Township 17 South, Range 16 East, within the town of Inglis in Levy County. The facility consists of a powerhouse located on the south side of the channel measuring about 28 feet wide by 115 feet long, drawing water from the Inglis By-Pass Channel, passing it through a single-pit type turbine and discharging downstream of the Inglis By-Pass Spillway Dam. Hy Power applied on August 4, 1998, to the Department for a MSSW permit for the same proposed hydroelectric facility on the Inglis By-Pass Channel. DESCRIPTION OF PROPOSED PROJECT The project involves the construction of an intake structure, powerhouse, and tailrace on a 0.61-acre area located on the south side of the existing Inglis By-Pass Spillway. The facility will take advantage of the existing hydrostatic head that exists on either side of the Spillway Dam, to generate electricity. The powerhouse will be constructed below grade and will contain a single megawatt turbine and generating unit. The intake structure will divert flows from the upstream side of the Spillway Dam through the powerhouse and back into the By-Pass Channel. A small one-story control building and low profile substation will be constructed above grade within the boundaries of the project area. The hydroelectric project is considered to be a "Run of the River" type of facility because it can only use that water which flows down the existing channel. The geometry of the channel restricts flow to a certain amount, therefore the project cannot create or use flows above those that the By-Pass Channel can provide. The overall authority for control of water levels in Lake Rousseau and flow to the lower Withlacoochee River will remain with the DEP. Lake Rousseau was created in 1909 when the Inglis Dam was constructed across the Withlachoochee River for the purposes of hydroelectric generation. The dam impounds over 11 miles of the Withlachoochee River and forms a lake approximately 3,000 to 4,000 acres in size. Prior to construction of the Barge Canal, water released from the Inglis Dam would flow down the lower portion of the Withlachoochee River about 10 miles before entering into the Gulf of Mexico. In the mid to late 1960's the Army Corps of Engineers (ACOE) built a portion of the Cross Florida Barge Canal between the Gulf of Mexico and Lake Rousseau. The canal severed the Withlachoochee River downstream of the Inglis Dam causing its flow to be diverted into the Barge Canal and then into the Gulf. In order to maintain the flow of freshwater from Lake Rousseau to the lower segment of the River, the 8,900-foot long Inglis By- Pass Channel and Spillway were constructed. The resulting downstream flow ensures navigation in the lower portion of the River and sustains its freshwater and estuarine environment. The water level in Lake Rousseau is generally maintained at an elevation of 27.5 feet above mean sea level (msl) by a combination of the Inglis Dam, the Inglis Lock, which is located in the Barge Canal, and the By-Pass Channel Spillway. These water control features are known collectively as the Inglis Project Works. The water levels in the lower Withlachoochee River immediately to the west of the By-Pass spillway are close to sea level. The resulting head provides the potential energy needed to drive the proposed generator turbine. Under normal conditions the majority of water released from Lake Rousseau flows over the Spillway Dam into the lower segment of the River. According to the DEP Office of Greenways and Trails (OGT), the maximum capacity of the existing By-Pass Channel Spillway is 1,540 cubic feet per second. The hydroelectric project will divert whatever flow is allowed around the existing spillway through the turbine and back into the channel. When the Cross Florida Barge Canal project was cancelled in the 1990's, the ACOE transferred ownership of the property to the State of Florida Board of Trustees, who in turn has leased the property to the DEP for use as the Cross Florida Greenbelt State Recreation and Conservation Area. Management of this property, the control of river flow and lake levels, and operation of the Inglis Project Works are exercised by the DEP's OGT. The OGT utilizes a document entitled "Water Control Plan for Inglis Project Works," dated September 1994, as a guide to operating the structures. The Water Control Plan is incorporated as part of the MSSW intent to issue. On or about April 25, 1995, the Governor and Cabinet, sitting as the Board of Trustees of the Internal Improvement Trust Fund ("Trustees"), approved a request from Hy Power to sublease 0.61 acres of Greenway property at the project site for the purpose of providing electric power. The request was challenged by Berger and the Campbells, and resulted in an administrative hearing held on November 3, 1995. As a result of the hearing, Administrative Law Judge Larry Sartin entered a Recommended Order on July 12, 1996, that the Board enter an order approving execution by the DEP of the proposed sublease and dismissing the petition of Berger and the Campbells. The Recommended Order was approved by the Trustees in its entirety in a Final Order dated April 12, 1996 ("Final Order"). Berger v. Southern Hy Power Corporation et al., Case No. 95-3589. A copy of the Final Order is listed as an exhibit to this Stipulation, and the Findings of Fact and Conclusions of Law contained therein are adopted herein. As previously ruled by the undersigned, the previous Final Order is res judicata as to Petitioners in this case, who are collaterally estopped from challenging any of the findings of fact or conclusions of law contained in the previous Final Order. Petitioners reserve the right to litigate issues of fact and law not addressed in the Findings of Fact or Conclusions of Law contained in that Final Order with regard to the permittability of this project under the WRM and MSSW permitting proposals, and to raise objections as to relevance to this proceedings of any of the Findings of Fact or Conclusions of Law in the Final Order. On February 21, 1995, Hy Power filed application with the Federal Energy Regulatory Commission (FERC) for a conduit exemption from the licensing requirements of Part I of the Federal Powers Act (FPA) for the proposed project. Petitioners and various other persons filed protests with FERC in opposition to the project. On April 21, 1997, FERC issued an Order Granting Conduit Exemption, a copy of which is listed as an exhibit to this Stipulation. Petitioners in this case are collaterally estopped from challenging any of the findings or conclusions contained in that Order Granting Conduit Exemption. Petitioners reserve the right to litigate issues of fact and law not addressed in the Findings of Fact or Conclusions of Law contained in that Order Granting Conduit Exemption with regard to the permittability of this project under the WRM and MSSW permitting proposals, and to raise objections as to relevance to this proceedings of any of the findings or conclusions in the Order Granting Conduit Exemption. FACTS ADDUCED AT HEARING OUTLINE OF PROJECT The proposed project calls for the construction of a water retention structure along the existing By-Pass spillway, the excavation of a large hole in which the powerhouse and turbine would be constructed "in-the-dry" south of the existing dam, and a millrace below the proposed project to return the water back into the existing water course. Conflicting testimony was received regarding the facts surrounding the construction of the project. These included: whether the proposed project will touch the existing wing walls of the existing dam; whether the water retention structure is a coffer dam; whether the proposed water retention structure will safely retain the water; whether the powerhouse and turbine have sufficient negative buoyancy to stay in the ground; whether the proposed excavation will weaken the existing dam; and whether the de-watering of the excavation site will adversely impact ground and surface water. PROJECT DESIGN AND ENGINEERING Engineering for the project was directed by witness Richard A. Volkin, a professional engineer and president and CEO of Engineering Company, Inc., based in Canton, Massachusetts. Mr. Volkin has extensive national and international experience in the design, management, and operation of hydroelectric facilities. Other engineers in Mr. Volkin’s firm worked on the project under Mr. Volkin’s direct supervision, including John May, who became registered as a professional engineer in Florida in order to sign and seal the engineering drawings for the project, which he initially did around 1994. Mr. May became ill and retired in 1998. Because of the length of time the application process has taken and the fact that Mr. May retired, there was a time while the application was pending, when Hy Power's design team was without a registered Florida engineer. When this was brought to the attention of Hy Power, Hy Power substituted Steven Crockett for Mr. May as the Florida-registered professional engineer of record for the project. DEP routinely accepts an applicant’s changing its engineer of record during the course of permit application or construction. Mr. Crockett is a civil and structural engineer who has considerable experience in preparing dam structural designs. Mr. Crockett independently reviewed and evaluated the engineering drawings for the project. Mr. Crockett resealed the drawings by using his drawn seal and signing the plans because his embossed seal was not readily available and time was of the essence. Mr. Crockett has advised DEP that he is now engineer of record for the project, using the appropriate DEP forms. Mr. Volkin’s firm performed all of the studies required by the various agencies, including a geotechnical study of the area, a 50-year analysis of water flow in and out of the Lake Rousseau regime, and water quality evaluations of water in the By-Pass Channel. The ACOE performed deep hole borings of the soils (approximately 36-40 feet below sea level) in the area of the project site to determine soil stabilization conditions at the site when they were constructing the Inglis Project Works. The soil conditions found can reasonably be expected to be similar today. Mr. Volkin’s company also took its own eight-foot deep surface core samples. The purpose of those samples was to verify the ACOE data. The new core samples verified the original core samples. Mr. Volkin also reviewed the ACOE’s engineering drawings developed from construction of the Spillway Dam. These show that the dam is founded on limestone bedding that has been stabilized with concrete. The hydroelectric facility will be constructed adjacent to and south of the dam structure and adjacent to and north of the barge canal. The same type of limestone bedrock is found in the area of the proposed construction. The facility design includes an intake channel on the upstream channel and a tailrace downstream. Those are the only structures that will be constructed next to the By-Pass Channel. The construction of the facility itself will be "in the dry." Hy Power will use coffer dams to seal off the construction site from the By-Pass Channel, so that there will not be water leakage from the Channel into the construction site. Water from the By-Pass Channel will enter the power plant when the coffer dams are lifted and the water is allowed to flow into the facility. The Petitioners presented the testimony of Bill Edwards, an individual with considerable experience in the construction of bridges, cofferdams, and similar concrete structures in aquatic and semi-aquatic conditions. Mr. Edwards is a former hard-hat diver who worked all over the world and worked in Florida for many years prior to his retirement. Based upon his experience and expertise in construction related to projects of this type, his testimony is credible and worthy of consideration. Mr. Edwards pointed out that if the proposed water retention structure did not touch the wing wall of the existing dam, it could not keep the water out and would not have the strength that it needed to retain the water. Hy Power’s witnesses explained that the retention structure would be set close enough to the existing wing wall that waterproofing materials could be placed between the two structures to keep the water out. Further, that the existing plans did not show interior bracing which would be included for structural strength and integrity. In sum, the retention structure will be in contact with existing dam’s wing wall, but will be free standing and not dependent upon the strength of the wing wall for its strength. Mr. Edwards pointed out that a cofferdam by definition has walls on all sides of the structure. The structure proposed by Hy Power did not have walls all the way around the proposed excavation. In rebuttal, Hy Power presented evidence that its plans were conceptual, design drawing and not construction plans. Hy Power represented that in actuality it would put as many walls as were necessary to keep the water out of the hole it intended to excavate. Trash racks will be constructed at the intake structures to protect aquatic life and make sure that trash and vegetation do not enter the intake structure or go down river. The trash rack bars will be two inches on center, which the U.S. Fish and Wildlife Service has determined as the appropriate size for the protection of fish. The turbine blades are "double regulated," and operate generally between 60 and 90 revolutions per minute. The design enables the turbine to operate at a constant speed to generate a consistent flow of electricity, notwithstanding the fact that the flow of the water may vary. The blade speed is not very fast, and the 2.5-meter blades provide a two to three-foot opening. This design acts to prevent fish mortality. There are four ways to shut off the flow of water through the proposed structure: close the pitch of the blades, close the wicket gates, allow the counter balance to the wicket gates to kick in and automatically close the gates, and close off the main gates. This is a fail safe system ("four level redundancy") designed to work upon any failure. Once water goes through the generator, its velocity is reduced to no greater than its intake rate which is a maximum of three feet per second. This prevents the water being discharged from the tailrace from causing erosion. If the head of water in the dam produces a flow exceeding three feet per second, it can be diverted over the other dams which will be functional. The power plant will be encased in concrete, except for a small access way that enables a person to go down a set of stairs to the plant. It will be a sealed, waterproof structure, as required by FERC and the ACOE. This will prevent penetration of groundwater, or flood waters in the event a massive flood overtops the plant. The only water entering the powerhouse will be through the turbine tunnel for power generation purposes. Mr. Edwards pointed out that the powerhouse was a closed structure and as such would have positive buoyancy, that is, it would float. Mr. Edwards pointed out that the proposed site is between the barge canal and By-Pass spillway and there is a great deal of groundwater and potentiometric pressure in the existing water table. In sum, there is a unlimited supply of groundwater at the site, and powerhouse could float out of the ground just like an empty swimming pool. Hy Power presented rebuttal evidence that the weight of the building, the turbine, and the water flowing through the turbine would be close to negative buoyancy, and they would add additional weight to the structure as necessary to keep it in place. The project is designed to generate three megawatts of electric power which is enough electricity to serve between 300 and 3000 homes, depending on usage. The project is designed to be unmanned. This is common for facilities such as this. The plant can be operated by remote control, unlike the existing controls at the By-Pass Dam, which are operated manually. DEP can access, monitor, and control remotely the generator's operation to include shutting the facility down at any time. There will be remote sensors to monitor water elevations. Flood protection will improve because of the ability of DEP to manage water flow from a remote location. If there is any major disruption, the plant will shut itself down. The project is classified as "green power." In other words, it generates natural energy without any disruption to the environment. The project will have minimal to no impact on the environment. There will be no significant changes in water quality compared to existing conditions as a result of either construction or operation of the facility. WRM Permit Criteria Hy Power has provided reasonable assurances that the proposed project will not cause a violation of state water quality standards of Section 403.918(a), Florida Statutes (1991). The parties stipulated that turbidity and dissolved oxygen were the two surface water quality issues of concern in this proceeding. The receiving water body is the Inglis By-Pass Channel. The Inglis By-Pass Channel is a Class III surface water. The project is not located in a OFW. While the lower Withlacoochee River is an OFW, the OFW designation runs up the natural river itself, and does not include the Spillway Dam, tailrace, or the remainder of the By-Pass Channel. There would be no degradation of water quality at the point of contact with the Withlacoochee River OFW. The DEP and FERC looked specifically at potential for turbidity and dissolved oxygen in determining whether the project would violate state water quality standards. The standards for turbidity and dissolved oxygen will not be violated. Because the By-Pass Dam is an under flow structure, a minimum of oxygenation currently occurs as water flows through the existing dam. The proposed project runs the water underground through the generator; however, Hy Power will measure the dissolved oxygen below the dam in the Lower Withlacoochee River. In the event there is any lowering of dissolved oxygen, Hy Power can install a "sparge ring" to reoxygenate the water going through the turbine so that dissolved oxygen remains at current levels. No turbidity will be added to the receiving water as a result of the project, because water velocity is low and the structure is encased in concrete and rip-rap. The only other potential for turbidity would occur when the coffer dams are removed after construction is complete. The coffer dams can be removed with the generator closed to permit any turbidity to settle. The amount of siltation that might occur when the generator is opened would be insignificant. Where a project is not in a OFW, an applicant must provide reasonable assurance that the project will not be contrary to public interest. See Section 403.918(2), Florida Statutes (1991). Hy Power has provided such assurances. The project will not directly affect public health, safety or welfare, or the property of others. See Section 403.918 (2)(a)1., Florida Statutes. There are concerns relating to the structural integrity of the proposed facility and adjacent structures which are discussed extensively below. The project will have no adverse impact upon the conservation of fish and wildlife, including threatened and endangered species and their habitat. See Section 403.918 (2)(a)2., Florida Statutes. While manatees are not likely to be found at the project site, the installation of the trash racks will eliminate any potential adverse impact on manatees. In fact, the racks will be an improvement over the current unprotected Spillway Dam. DEP procedures require a specific manatee control plan be implemented to deal with site specific concerns. The project will not adversely affect navigation or the flow of the water or cause harmful erosion or shoaling. See Section 403.918(2)(a)3., Florida Statutes. The project will not adversely affect fishing or recreation values or marine productivity in the vicinity of the project. See Section 403.918(2)(a)4., Florida Statutes. The permanent project and its construction will cause no significant environmental impacts. See Section 403.918(2)(a)5., Florida Statutes. There will be no adverse impacts to significant historical and archeological resources. Section 403.918(2)(a)6., Florida Statutes. With regard to the impact on current conditions and relative value of functions being performed by the areas affected by the proposed activity, there will be no negative impacts. See Section 403.918(2)(a)7., Florida Statutes. Improvement will result from better control of water flow at the project site, installation of trash racks and implementation of green power. THE FORESEEABLE ADVERSE SECONDARY OR CUMULATIVE IMPACTS Potential adverse secondary impacts related to power transmission are addressed through the fact that there is an existing power line corridor that can be used to transmit the electricity. Any need to change the corridor could be addressed by subsequent DEP permitting. Cumulative impacts are not at issue. Mr. Gammon, with Florida Power, acknowledged that the current electric company, presumably Florida Power, would be required by FERC to transport the electricity generated by Hy Power over its existing corridor and poles. No final decision has been made regarding how to access the site with equipment during construction. Several feasible construction options exist, and there are several ways of accessing the site with heavy equipment vehicles and without impacting wetlands. Any final decision would be subject to DEP approval. Since the project meets the public interest criteria of Section 403.918(2)(a), Florida Statutes, and wetland impacts are minimal, the project is permittable without the need for mitigation. See Section 403.918(2)(b), Florida Statutes. The ACOE has issued a permit for the facility. The permit varies slightly from the DEP intent to issue in the use of reinforced concrete rather than rip-rap on the bottom half of the intake channel. This is to comply with ACOE preference, but the variation has only an environmental benefit. Counsel for Petitioners sought to elicit testimony from Linda Sloan, Executive Director of the Withlacoochee Regional Planning Council, with regard to compliance of the proposed project with the Town of Inglis Comprehensive Plan and Land Development Code. Such compliance is not relevant to this proceeding. At any rate, Ms. Sloan conceded that any prohibition that might apply in the Land Development Code to construction of the proposed facility could potentially be alleviated by exemption or variance provisions in the Code. MSSW PERMIT CRITERIA The project will provide adequate flood protection and drainage in the conventional sense. See Rule 40D-4.301(1)(a), Florida Administrative Code. Because the amount of impervious area is minimal, runoff from the project will not in any way contribute to increased flooding or adversely impact drainage patterns. The total amount of impervious area of the facility is less than that of a single-family residence. SWFWMD rules do not even require MSSW permits for single-family residences because the impact is not significant. The only purpose for requiring a MSSW permit for the project is to review the project’s potential downstream impacts to the watershed, not stormwater runoff from the facility itself. The project will not cause adverse water quality or water quantity impacts on adjacent lands in violation of Chapter 373, Florida Statutes, or cause a discharge that violates state water quality standards. See Rule 40 D-4.301(1)(b), Florida Administrative Code. As indicated by the WRM water quality findings above, the project will not generally violate state surface water quality standards. See Rule 40 D-4.301(1)( c), Florida Administrative Code. The project will not generally cause adverse impact on surface or groundwater levels or flows. See Rule 40 D- 4.301(1)(d), Florida Administrative Code. Since the project is a run-of-the-river, it will not diminish the capability of a lake or other impoundment to fluctuate through the full range established for it under Chapter 40D-8, Florida Administrative Code. The project will not cause adverse environmental impacts, or adverse impacts to wetlands, fish, and wildlife or other natural resources. The project can be effectively operated and maintained. See Rule 40D-4.301(1)(g), Florida Administrative Code. The project is a slow speed, low maintenance facility. The design concept is well established and has been successfully used for many years. Possible adverse affects to public safety are discussed below. The project is consistent with the requirements of other public agencies. See Rule 40D-4.301(1)(i), Florida Administrative Code. Potential harm to water resources within the SWFWMD are discussed below. See Rule 40D-4.301(1)(j), Florida Administrative Code. The proposed project generally will not interfere with the legal rights of others. See Rule 40D-4.301(1)(k), Florida Administrative Code. The proposed project is not against public policy. See Rule 40D-4.301(1)(l), Florida Administrative Code. The project complies with the requirements contained in the Basis of Review. See Rule 40D-4.301(2), Florida Administrative Code. There is a dispute as to whether the project was within or at the edge of the 100-year flood plain. This dispute is related to how one interprets the rule as it relates to the millrace and the location of the facility which is under ground. In the conventional sense, the project is not in the flood plain. Further, the project is designed in such a way, that it is waterproof if it were topped with water. While in the past SWFWMD may have had concerns that the project might cause downstream flooding, SWFWMD currently has no such concerns, given the run-of-the-river status of the proposed project. The operation of the project will not cause downstream flooding. The DEP included in its intent to issue, conditions contained in the sublease between Hy Power and the DEP in order to ensure that the facility would remain run-of-the-river, would comply with the water control plan, and would otherwise comply with the terms of the sublease. The DEP has final control over water flow and can revoke the permit or otherwise take enforcement action against Hy Power if Hy Power fails to comply with the water control plan. GROUNDWATER IMPACTS Operation of the project will not cause groundwater contamination or otherwise have adverse groundwater impacts. Some concerns about groundwater during excavation of the construction site were raised. The conflicting evidence received regarding them is discussed below. An area of concern was the de-watering plan for the project. Everyone agrees there will be some water seepage into the construction site that will have to be pumped out. The parties disagree regarding the amount of water that will have to be removed. Their estimates of amount of water to be removed vary because their estimates of size and over-all depth of the site vary. Petitioners presented credible evidence that a potential exists for the construction site to have a large quantity of water because of its location between two sources of surface water (the By-Pass Channel and Barge Canal), because of the makeup of the subsurface, and because of the depth of the construction. Hy Power credibly represents that if excessive groundwater is found, it can address the adverse impacts through its de-watering plan that would have to be filed with FERC and DEP. The technology exists to address the de-watering of the project. Such plans are routinely considered by DEP after a construction permit is issued and before de-watering occurs. There is very little evidence of sinkhole activity in the project area, and the construction activities are not expected to cause any sinkhole activity. NOISE POLLUTION Mr. Bitter expressed concerns that FERC would require the facility to install a very loud siren that would result in sudden noise adverse to the well-being of neighbors. Mr. Bitter is unfamiliar with FERC siren requirements at run-of the-river hydroelectric facilities. In contrast, Mr. Volkin, who has substantial experience in this area, testified that the only alarm device that would be required would be for the protection of the workers during construction. The purpose of the alarm is to warn persons below a dam spillway of a change in the volume of water being let out of the impoundment. In the case of a run-of-the-river facility, the volume is near constant, changing only gradually. Therefore, even if a warning siren had to be installed its use would be limited to significant changes in flow or testing. This would not constitute a nuisance. Further, the facility is located in the vicinity of the Crystal River Nuclear Power Plant which has its own warning sirens. It would be prudent to make any warning devices required for this structure significantly different from those at the nuclear plant and to limit their use. DAM SAFETY AND FERC REVIEW In reviewing whether Hy Power’s applications complied with the relevant permitting criteria, the DEP took into consideration the review of the facility already performed by FERC. FERC will also be responsible for reviewing the project as it is being constructed. Mr. Edwards also raised concerns about the structural stability of the By-Pass Dam itself. This has been a subject of concern by those responsible for the dam, and a survey of the structure was conducted in 1993, referred to as the Greiner Report. The Greiner Report identified specific maintenance problems that have been and are being addressed by the DEP. However, DEP’s maintenance plan does not address specifically the possibility that the weight of the dam over time has caused some shifting in the dam. Hy Power has only a few core borings and only one at the location of the generator. Hy Power is using the ACOE’s original borings, as confirmed by several new ones, to develop its preliminary plans. The DEP considered FERC and the ACOE as responsible agencies for determining the structural integrity of the dam. DEP has taken FERC’s review of this facility into consideration as part of DEP’s own permitting review. It is normal for DEP to rely on outside sources and agencies for assistance in determining compliance with DEP permitting criteria such as public health and safety, and it is reasonable for DEP to do so in this instance. Most states do not have the full capability to evaluate dam safety, and so they rely on FERC and ACOE. On April 21, 1997, the project received a conduit exemption from FERC. The application process is illustrated in Hy Power Exhibit 11. Hy Power submitted to DEP detailed information about the dam, the associated structures and the proposed project which had been reviewed by FERC and the ACOE, the two agencies in the United States who are responsible for dam structure design, control, and administration. Included in the package was the Greiner Report and Hy Power’s review of it. FERC evaluated the project, the Inglis By-Pass Dam structure, and the proximity of the project to the Dam in relation to structural impact, upstream and downstream impacts, water quality, and environmental issues. Mr. Edwards raised concerns regarding the ability of the limestone bedrock to sustain additional construction in the area of proposed construction. This is a material issue in the controversy which impacts several aspects of the proposed construction. Mr. Edwards pointed out that the barge canal channel was constructed with the use of explosives that caused a fracturing of limestone bedrock. He pointed out that the steel panels, which Hy Power proposes to drive into the bedrock to construct the water retention structure necessary to excavate the hole into which the turbine and powerhouse would be placed, will further fracture this bedrock. This creates two potential dangers. It could permit water to move under and around the bottoms of the panels, potentially scouring the loosened material from the base of the panels and making them unstable and subject to failure. It could weaken the entire southern wing of the existing spillway dam. Mr. Edwards opined that this could result in catastrophic failure of the dam or the coffer dam. Such a failure would cause major destruction and loss of life to those persons living and working in and along the lower Withlacoochee River. Hy Power presented rebuttal evidence that it could and would, if necessary, inject concrete into the limestone to stabilize it and avoid the concerns raised by Mr. Edwards. FERC specifically evaluated concerns raised by project opponents over the poor physical condition of the By-Pass Channel Spillway structures, relying particularly on the 1993 Greiner Report. FERC noted that the DEP had entered into a contract to correct any deficiencies listed in the Greiner Report, which "did not conclude that the deficiencies at the By-Pass Spillway threaten downstream life and property." The FERC review concluded that the dam was safe. To ensure safety, FERC is requiring that Hy Power do a complete stability analysis of the dam prior to any construction. Articles 301 and 302 of the FERC exemption ensure that all final drawings and specifications be submitted to FERC prior to construction, along with a supporting design report consistent with FERC’s Engineering Guidelines; that FERC can require changes to assure a safe and adequate project; and that Hy Power must also submit approved coffer dam construction drawings and specifications at least 30 days prior to starting construction. FERC has its own engineering staff who will go to the site and do their own analysis, along with the ACOE, of the dam and structures, prior to any construction commencing. This is a detailed design review evaluation so that the latest information on the dam will be made known immediately prior to construction, and will prevent any catastrophic event from happening. Under FERC procedures, FERC requires the applicant to obtain the DEP permits prior to requiring applicant to submit more detailed construction designs for FERC's consideration. These more detailed designs in turn will be subject to further review by DEP and FERC. It is assumed that Hy Power will comply with the post- permitting procedures and requirements, and will present complete, detailed construction drawings for FREC and DEP approval. Hy Power’s failure to complete the process would result in denial of a construction permit.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law set forth herein, it is RECOMMENDED: That the DEP enter a Final Order that issues the two permits challenged in this proceedings, WRM Permit No. 38-237096-3.001 and MSSW Permit No. 38-0129249-002, subject to the conditions contained in the Intents to Issue in the respective WRM and MSSW Permits and as described in the Recommended Order.

The Issue The issue in this case is whether the Orange County Parks Department is entitled to a dredge and fill permit from the Department of Environmental Regulation for the construction and installation of a boat dock on Lake Down.
Findings Of Fact The Application On November 1, 1989, Orange County Parks Department (Orange County) applied for a dredge and fill permit to construct a floating boat dock in the Town of Windermere on Lake Down. The application, which is dated September 7, 1989, describes the proposed project as a "public improvement of an existing boat ramp facility." The application describes a floating dock attached by short hinged sections to fixed docks that would be affixed, at normal water elevations, to upland. The application explains that the purpose of the dock is to accommodate boats and pedestrians in loading and unloading boats at the ramp. The dock would, according to the application, reduce wave and wakedisturbance action on the existing shoreline and thus reduce the current rate of erosion at the site. The application assures that no existing vegetation would be disturbed except in the area of the fixed docks. According to the application, the floating dock and two fixed docks would measure about 420 feet long by 7 feet wide with several wideouts of about 10 1/2 feet. The dock is designed to moor 15-18 boats simultaneously. The location map attached to and a part of the application shows that the dock would be at the southernmost extent of Lake Down. The survey attached to and a part of the application provides submerged and upland elevations in the vicinity of the proposed dock. The survey states that the water elevation of Lake Down is 98.8 feet. Nothing indicates whether 98.8 feet is the average water elevation or the water elevation on the date of the survey on June 28, 1989. Other portions of the application describe the composition of the dock parts. The only parts in contact with the water would be galvanized steel pilings, which would be jetted or driven not more than 15 feet deep into the submerged bottom, and plastic floats attached to the bottom of the dock for floatation. The application also indicates that construction-period turbidity would be controlled through the use of turbidity curtains. Another diagram attached to and a part of the application superimposes the dock over the submerged elevations. A note on the diagram states that, under "Plan 1 and Plan 2, Orange County would excavate existing grade under floating dock to elev 97.0." The applicant proposed excavation under the dock due to the shallowness of the water under and lakeward of the dock. The diagram depicts a dock that would run parallel, rather than perpendicular, to the shore. The diagram discloses that the proposed dock would begin immediately east of the existing boat ramp. The diagram indicates that the floating dock runs about 390 feet. The elevation at the northwest corner of the west fixed dock is about 100 feet. At what the construction drawings call "average lake elevation" of 99.5 feet, the piling at the northwest corner of the west fixed dock would thus not be submerged. About 15 feet to the east of the northwest corner, where a hinge connects the west fixed dock to the floating dock, the elevation is between 98 and 99 feet. At average water elevation, the shoreside of the floating dock generally ranges from five to ten feet from the shoreline, with extremes of one foot at the southeast corner of the west fixed dock and 17 feet about 220 feet east of this point. The submerged elevations change significantlyunder the 390 feet of floating dock. On the lakeside, where boats would dock, the following elevations exist under the dock at 40 Dock interval 40' 80' 120' 160' Lakebottom elevation 95-96' 95' 92' 93' 200' 240' 280' 320' 360' 390' 91-92' 91' 92-93' 93-94' 96' 96' The submerged elevations are higher (and thus water depths shallower) on the shoreside of the dock, which would not be accessible to boats. For the back of the floating dock, the submerged elevations exceed 97 feet for the westernmost 40 feet and a short segment at the eastern end of the floating dock; the remaining elevations are less than 97 feet. Unlike the west fixed dock, which would stand almost entirely in upland even at average water elevation, the east fixed dock would stand almost entirely in water at the same water elevation. Also, the west fixed dock would be relatively small and run parallel to the shore beside the ramp. The east fixed dock would be oriented in a northwesterly direction from, and perpendicular to, the shore. The northwest and northeast faces of the east fixed dock would be accessible by boats. The submerged elevation under the northwest face, which is between 15 and 20 feet offshore from the average shoreline, is between 95 and 96 feet. The water depth adjoining the northeast face is shallower because the northeast face, although accessible to boats, would runupland, past the average shoreline at 99.5 feet, to an upland elevation of about 101 feet. The rate of drop of submerged elevation is uneven along the length of the proposed floating dock. Water depth increases more rapidly from the center of the floating dock. For instance, at the 200-foot interval from the west end, the elevation drops from about 91.5 feet at the front of the dock to 88 feet at a point ten feet lakeward of, and perpendicular to, the dock. In other words, the water becomes 3 1/2 feet deeper in the first ten feet. The lakebottom drops more gradually at the west and east ends of the proposed dock. For instance, at the 40 increase in depth ten feet out is only about 2 1/2 feet. At the north corner of the east fixed dock, the increase in depth ten feet out is only about 1 1/2 feet. The diagram also depicts the existing boat ramp that would be served by the proposed dock. The ramp, which is oriented in an eastnortheasterly direction from the shore, is less than ten feet north of the proposed west fixed dock. The ramp measures about 20 feet wide upland and about ten feet wider farther out into the water. The elevation of the submerged north corner of the lakeward end of the boat ramp is between 94 and 95 feet. The elevation of the submerged south corner of the lakeward end of the boat ramp is between 95 and 96 feet. The lakebottom isfairly flat at the boat ramp. Over its 40-foot length, the elevation of the ramp changes by only about 5 feet. A separate diagram attached to and a part of the application depicts the floats that would be attached to the bottom of the decking. The floats would be about 18 inches high and draw about three inches of water when the dock is supporting no weight. A 40-inch high railing would run along the back of the dock. However, the railing would not extend along the northwest and northeast faces of the east fixed dock. Thus, nothing would deter a boat from docking along these two faces of the east fixed dock. On November 9, 1989, Orange County filed an application amendment, which contains drawings that eliminate all excavation. The amendment states: "Dock will be relocated if conflict with existing shore occurs." This amendment was filed at the urging of a DER representative, who would not have recommended the application for approval without the change. There are other suggestions in the record that Orange County would be willing to amend its application to locate the proposed dock farther from shore and in deeper waters. However, Orange County did not specifically offer an amendment, and the record offers no indication where the dock would be, if Orange County again amended the application. On June 20, 1990, Orange County informed the Department of Environmental Regulation (DER) by letter that the legal description provided with the application was inaccurate. The letter provides a new legal description and a list of adjoining property owners. Mr. Rosser, Ms. Grice, and Mr. Patterson own property adjacent to the proposed project or reside in close proximity to Lake Down so as to be substantially affected by any material degradation of water quality. The new legal description encompasses only 1.46 acres rather than the 12.16 acres set forth in the original application. The land eliminated from the application is west and north of the existing boat ramp. Orange County plans to make considerable improvements to the existing boat ramp, such as by the addition of substantial parking and a septic tank on the land eliminated from the original application. However, the present application does not request any permit for such work. The Intent to Issue On February 26, 1990, DER filed an Intent to Issue the permit for which Orange County had applied. The Intent to Issue indicates that the permit is to construct a floating dock on Lake Down about 420 feet by 7 feet, plus wideouts, and notes that the request to dredge along the dock had been withdrawn. According to the Intent to Issue, the bank between the north side of Conroy-Windermere Road and the shoreline has eroded, probably as a result of boaters pulling their boats onto shore for temporary mooring. Although DER did not determine the water elevation on the date of the inspection, the Intent to Issue reports that water depths range from a few inches alongshore to about three feet at the shoreside of the proposed dock. The Intent to Issue notes that Orange County is currently trying to condemn the land north and west of the boat ramp to upgrade the launching facility with a larger ramp, picnic area, and parking spaces for between 50 and 100 vehicles. The Intent to Issue finds that the proposed docking facility and its associated boat traffic would not result in violations of state water quality standards nor degradation of ambient conditions in Lake Down or the Butler Chain. Except for limited construction-period turbidity, which could be controlled with a siltation barrier, displacement or disruption of the lakebottom would reportedly occur only during piling installation, and shoreline vegetation would be removed only at the fixed docks at either end of the floating dock. Addressing prop dredging, the Intent to Issue notes: It is not anticipated that damage to the lake bottom will result from boats moving into and away from the dock. If water levels fall to particularly low levels, the county can close the ramp until adequate depth is available again. Addressing the possibility of increased boat traffic on the lake, the Intent to Issue states: It is not anticipated that use of ramp will significantly increase as a result of the proposed construction. Those individuals who are seriously interested in accessing the Butler Chain have done so despite the poor facility currently available. The new dock will provide mooring capability without causing shoreline erosion. Furthermore, the dock will provide a safer place for boatersto walk and wait. Presently, because there is no onsite parking nor mooring available, boaters park vehicles to the east of the boat ramp site in an undeveloped parcel. They then walk west along Conroy-Windermere Road while sharing the road shoulder with vehicles and trailers. The dock, in combination with the proposed (upland) sidewalk won't shorten the distance to be walked but will remove pedestrians from the roadway sooner to the relative safety of the mooring area. The Intent to Issue concludes that Orange County has provided reasonable assurance that the project will not result in violations of state water quality standards and that the project is clearly in the public interest. Thus, DER expressed its intent to issue the permit, subject to various conditions, in the absence of a timely filed petition. Specific condition 7 of the Intent to Issue addresses the issue of prop dredging: When the lake level drops to the point where boats entering and leaving the dock cause damage to submerged bottoms in the immediate area, the county shall close the ramp and dock until the water returns to acceptable levels. Specific condition 8 addresses the County's plans for additional improvements for the boat ramp facility: Issuance of a permit for the dock does not guarantee nor infer issuance of a permit orpermits for further improvements to the county boat launching facility. Additional Findings Regarding Upland Orlando and the more densely populated areas are generally to the north and east of the boat ramp; Orlando itself is about 10 miles away. The center of the Town of Windermere, which numbers about 1400 persons, is to the west of the boat ramp. About 80% of the users of the boat ramp approach the ramp from the east. A small vehicle-maneuvering area adjoins the ramp on the west. After unloading the boat into the water, the driver of the trailer-towing vehicle typically drives east on Conroy-Windermere Road about 1600 feet and parks on the south side of the road in a large unimproved lot. The County's permission to use the lot is terminable by the owner without notice. While the vehicle and trailer are being parked, the person or persons with the boat normally start the engine and idle just offshore from the ramp or moor on the sandy beach immediately east of the boat ramp. After parking the vehicle, the driver generally crosses to the north side of Conroy-Windermere Road and walks along a sidewalk running from the parking area to what would be the east end of the proposed dock. The road and the sandy beach are separated by a thin strip of thick vegetation. Pedestrians continuing westalong the road, past a point across from the east end of the beach, must walk in the staging lane designed for vehicles waiting to enter the maneuvering area. An existing sidewalk on the south side of the road, which runs east of the ramp area, is not used as much because the sidewalk ends almost 800 feet east of the parking area. Pedestrians typically rejoin their boat at some point along the sandy beach immediately east of the boat ramp. When the boat is spotted, the pedestrian cuts through the vegetation on one of four or five paths running at intervals between the north side of the road and the beach. Traffic on these paths has worn them down noticeably from the prevailing elevations on either side. The same pattern is repeated upon the return of the boat, which is temporarily moored onshore to allow the driver to disembark, take the nearest path to the road, walk along the north side of the road to the parking area, cross the road, and return with the vehicle to the boat ramp. Normal summertime usage, when the boat ramp is used more frequently, involves a range of 30-65 boat launchings per day from the boat ramp. However, peak usage is much higher; nearly 400 trailers have been in the parking area at one time. Present upland usage of the boat ramp area is risky. The staging lane mixes pedestrians and motor vehicles towing trailers. The speed limit on Conroy-Windermere Road is 35 miles per hour at the parking area and 30 miles per hour at theramp, so westbound traffic is still moving rapidly past the staging lane. Also, Conroy-Windermere Road, which is an urban collector, is heavily travelled with an average daily traffic count of 9400 vehicles. Pedestrians crossing the road at the parking area 1600 feet west of the ramp must cross 22- 24 feet of highway. Pedestrians crossing the road at the boat ramp must cross about 50 feet of highway due to the presence of the staging lane and a painted median. Upland safety would be enhanced by separating pedestrians from the staging lane. However, the addition of the floating dock would not eliminate the risks associated with upland usage of the boat ramp. Persons still would be required to cross Conroy-Windermere Road, although a proposed crosswalk would reduce present risks somewhat. In addition, the existing sidewalk on the north side of the road would be reconfigured to lead to the floating boat dock, which would be incorporated into the sidewalk system leading toward the center of the Town of Windermere. For some persons using the dock segment of the sidewalk, such as young children and the disabled, close proximity with the water and mooring boats might prove unsafe. Conroy-Windermere Road has existed for many years, but the portion of the road parallel to the proposed dock was added only about 30 years ago. Previously, the road had turned south, but, following a serious traffic accident, the curve was straightened. Large amounts of fill were added to form the roadbed across the southern tip of Lake Down, which consequentlywas cut off from the remainder of the lake. This fill forms the bank leading to the shoreline directly parallel to the proposed dock. The boat ramp has also existed for many years. Years ago, grove trucks drove down to the lake in order to take on irrigation water. From time to time, persons would put in canoes at this point. Until the late 1960's, when Orange County paved the ramp, few if any powerboats were launched from the area or even used the lake. Today, the overwhelming majority of boats using the ramp currently are gasoline-powered motorboats. There are no restrictions on Lake Down as to the size of engine permitted on the lake, and the posted speed limit is 36 miles per hour. The area surrounding the boat ramp features few amenities. Apart from the maneuvering area, staging lane, and ramp itself, the only other improvements are an enclosed portable toilet and a dumpster garbage container. The Town of Windermere operates two boat ramps on the Butler Chain-- one on Lake Down and one on Lake Butler. Use of these ramps is reserved for Town residents and their guests. The remaining boat ramps on the chain are owned by corporations or private associations. Some boat traffic on the lake is from the use of private boat docks owned by persons owning lakefront land. Lake Down and the Butler Chain Designation as Outstanding Florida Waters By report dated January, 1984, DER recommended that the Environmental Regulation Commission designate as Outstanding Florida Waters the Butler Chain of Lakes: Lake Down, Lake Butler, Wauseon Bay, Lake Louise, Lake Palmer, Lake Chase, Lake Tibet, Lake Sheen, Pocket Lake, Little Fish Lake, and their connecting waterways. The January, 1984 report (DER Report), states that the Butler Chain drains into the Upper Kissimmee River Basin. Noting that Lake Down is the northernmost lake in the chain, the DER Report states that water flow in the lakes, which are interconnected by a series of man-made navigable canals, runs from north to south. Reviewing Florida and applicable federal anti-degradation policies protecting high quality waters, the DER Report states: This antidegradation policy is predicated on the principle that resources are so precious that degradation should not occur except after full consideration of the consequences and then only to the extent necessitated by important economic and social development. Scientifically, the principle is a valid one in that history has taught that adverse effects are difficult to predict. As scientific knowledge grows, previously unknown effects are discovered, and it is prudent to preserve our natural resources in the face of the unknown. DER Report, January 11, 1984 memorandum from DER to Environmental Regulation Commission, page 4. The Butler Chain covers 4700 acres. The largestlake is Lake Butler, which consists of 1665 acres. Lake Down, which is the third largest, consists of 872 acres. Depths of the lakes range from 15-30 feet. According to the DER Report, the upper seven lakes are oligo-mesotrophic with low productivity, high water clarity, and deeper waters. The lower three lakes (Sheen, Pocket, and Fish Lakes) are mesotrophic, with moderate productivity, high coloration of water, and shallower waters. The DER Report states that the water quality of the lakes is excellent. Lake Down had the highest level of dissolved oxygen: 7.1 mg/l. Biochemical oxygen demand was extremely low, in most cases, including Lake Down, less than 1.0 mg/l. Lake Down also had the lowest presence of chlorophyll a, which is a measure of the presence of algae, and a higher degree of biologically diversity, which is typical of a clean, soft-acid lake, according to the DER Report. The DER Report concludes that: An OFW designation will preserve the present environmental values of the Butler Chain of Lakes without any important environmental costs. The existing ecosystem and recreational use of the lakes is dependent upon the maintenance of sufficiently high levels of water quality, which an OFW designation would help to ensure. Id. at 23. The DER Report also includes a May, 1975 report of the Orange County Pollution Control Department, which concedes that the Butler Chain is: one of the few clean water systems left in the Central Florida area. The balance between available nutrient concentrations and the biotic communities has maintained an ecosystem free from the problems that are associated with more enriched systems. The balance is fragile and not well understood. Any activities which would effect this system will express itself [sic] in the aquatic habitat. May, 1975 report, page 4. At the time of its designation, the proposal received numerous endorsements and no objections. On August 16, 1983, The Orange County Board of County Commissioners passed a resolution urging DER to designate the Butler Chain as Outstanding Florida Waters. The Orange County Property Appraiser also supported the designation. In a letter to DER dated September 30, 1983, the appraiser warns that pollution could decrease surrounding property values and cost taxpayers substantial sums for cleanup. Additional Findings Regarding Lake Down Effect of Addition of Floating Dock 53. Neither the submerged galvanized steel pilings nor the plastic floats would allow materials to leach into the lake so as to affect measurably the composition or quality of the water. The increased turbidity during construction of the proposed floating dock also could be controlled so as not to have a significant effect on Lake Down. 2. Relevant Water Levels Water levels have fluctuated considerably in Lake Down. Since January, 1960, to present, the lowest recorded water elevation was 93.86 feet in February, 1987, and the highestelevation was 101.58 feet in August, 1960. Recorded water elevations were less than 97 feet from October, 1977 through August, 1979 and September, 1980 through November, 1982 (during which time the elevation attained 96 feet only six months). Water elevations were between 97 and 98 feet, inclusive, for an additional 29 months during this 31-year period. From March, 1987 through May, 1989, water levels were between 99 and 100 feet, attaining 100 feet only in December of 1987 and 1989. From June through August, 1989, water levels were between 98 and 99 feet. From September, 1989 through the date of the final hearing, water elevations were below 97.8 feet. From mid-March, 1990 through the date of the hearing, water elevations dropped from 97 feet to 96 feet; at the time of the hearing, the water elevation was about 96 feet. When the water elevation is 97.8 feet or less, the canal to Wauseon Bay and, from there, to Lake Butler is impassable to all but very small flatbottom boats. At these times, boat traffic tends to concentrate on Lake Down. Three witnesses for the County and DER testified as to the relationship between the water level of the lake and the operation of the floating dock. One witness for the County testified that the dock would float at 99.5 feet, which corresponds to ordinary high water. The designer of the dock testified that the east and west ends of the dock would cease floating at 96 feet. The DER representative testified that the dock and, pursuant to Special Condition 7, the ramp should beclosed at depths less than 95 feet. The meaning of Special Condition 7 is unclear. First, it is not clear what is meant by boats causing damage to submerged bottoms in the immediate area. Probably, this phrase means actual contact between the prop and bottom, which is known as prop dredging. Thus, boats cause damage to submerged bottoms when the depth of the water is about one foot or less. Special Condition 7 probably ignores the effect of prop wash, where the prop disturbs the bottom, including vegetation, by turbulence rather than direct contact. The second major ambiguity in Special Condition 7 cannot be resolved on the basis of the present record. The question is whether the ramp and entire dock must be closed whenever the water depth under any part of the dock is one foot or less (recognizing that the floats require about one foot of water). In the alternative, Orange County could close only that part of the dock as to which the underlying water depth is one foot or less. It is likely that DER and Orange County have different opinions on this question, with the County taking the latter position. Regardless how Special Condition 7 is construed, it fails to address the damage to submerged bottom that the"floating" dock will do when parts of it begin to ground. When partly grounded, the floating dock will pound up and down on the lakebottom in response to wave action and traffic on the dock. Over 40 feet of the shoreside of the dock will be grounded at water elevations of 97 feet or less, which, without regard to the effect of dock loading or wave action, is the point at which "dock dredging" commences. Water elevations have been less than 98 feet for a total of nearly seven of the last 31 years. The east and west ends of the lakeside of the floating dock would also begin to ground at a water level of about 97 feet. By the time water elevation falls to 96 feet, which existed at the time of the hearing, at least 80 feet of the west end of the floating dock and at least 30 feet of the east end of the floating dock would be grounded, again assuming no wave action and no load on the dock. Additionally, prop dredging would also take place at water elevations of 97 feet immediately adjacent to the dock, at its east and west ends. These water elevations have been experienced for a total of over four of the last 31 years. Another feature of the design of the proposed dock makes it likely that prop dredging will take place regardless of the water elevation. A popular area of the proposed dock would be the east fixed dock because it would be the closest point, by more than 100 yards in some cases, to the existing parking area. Boats could approach the northeast face of the east fixed dock up to an elevation of 101 feet. In other words, except in periods of unusual high water, some boats could and probably would use a section of the fixed dock in the same manner as temporary moorings are made today: in effect, by running up onto the beach. Prop dredging of the bottom would take place if boats approached the northwest face of the fixed dock when the water level fell to about 96.5 feet. The same is true for at least the first 40 feet of the west end of the floating dock. The resuspension of bottom sediment by prop wash would begin at depths of anywhere from 18 inches to seven feet, according to the testimony of the DER representative. Although important variables, such as the composition of the bottom and size and speed of the prop, affect prop wash, significant prop wash takes place for at least three feet under the prop. If three feet were the minimum depth necessary to avoid prop wash and, thus, lakebottom damage, the east 160 feet and west 70 feet of the floating dock would not be usable at water levels not exceeding 96 feet, such as at the time of the final hearing. The significance of lakebottom damage is great under and lakeward of the proposed dock. A thick carpet of bogmoss begins about ten feet offshore, which is roughly where the dock would begin, and continues out into the lake. Bog moss, which captures and retains sediments, would be damaged by the dredging action of the pounding floating dock when it begins to ground and boats using the floating dock at water elevations described in the preceding paragraphs. The phosphorus-rich sediments would then be resuspended in the water column. 3. Ambient Water Quality One of the key elements to preserving the health of Lake Down is to avoid conditions that can lead to the presence of excessive nutrients in the system. The presence of excessive nutrients, which leads to eutrophication, usually occurs because of the increased availability of a limiting nutrient. The limiting nutrient in Lake Down is phosphorus. Thus, a condition precedent to the eutrophication of Lake Down is an increase in the level of phosphorus in the water. The presence of phosphorus in the water can be detected directly, by measuring the phosphorus itself. The presence of phosphorus can also be detected indirectly, by measuring the effects of the nutrient or conditions that may result in the release into the water of additional phosphorus. Indicators of the nutrient levels of a lake include the presence of chlorophyll a, which, as a measure of the amount of algae in the water, is an indicator of the enrichment process. As a lake proceeds from an oligotrophic to a mesotrophic condition or from a mesotrophic to a eutrophiccondition, the presence of algae and chlorophyll a will increase. Indicators of conditions that may result in the release of additional phosphorus into the water include turbidity measurements and clarity data, such as Secchi depths. The sediment found in the submerged lakebottom contains greater concentrations of phosphorus in various organic and inorganic and soluble and insoluble forms than the water column itself contains. When this sediment is disturbed, part of the previously trapped phosphorus is released into the water column. The phosphorus is thereby made more readily available for supplying the nutrients necessary to contribute to the enrichment process, at least until the phosphorus settles back into the sediment where it can be locked up until redisturbed. As relevant to this case, the ambient water quality of Lake Down in the baseline year can largely be assessed in terms of the following data, which are obtained from Orange County Exhibit 13: chlorophyll a: 1.01 ug/l; turbidity: 1 NTU; total phosphorus: .01 mg/l; Secchi depth: 3.5 meters; and pH: 5.97. In the year ending immediately preceding the filing of the County's application, the following data were collected, according to Orange County Exhibit 13: chlorophyll a: 1.59 ug/l; turbidity: .75 NTU; total phosphorus: .01 mg/l; Secchi depth: over 3.5 meters; and pH: 6.36. In the summer of 1990, when the hearing took place, the County's expert collected from Lake Down the followingaveraged data, which are shown on Orange County Exhibits 15 and 17: chlorophyll a: 1.22 ug/l; total phosphorus: .011 mg/l; Secchi depth: over 4 meters; turbidity: 1.0-1.2 NTU's; and pH: 6.97. In the same summer, the Town of Windermere's expert collected the following data from Lake Down: turbidity: 0.92-1.8 NTU's; pH: up to 7.2; and total phosphate: .04-.05 mg/l. The only finding materially different from the findings of the County's expert is the amount of total phosphate. The findings of both experts are credited. The higher finding is supported by, among other things, the recording in the County's records of .037 mg/l of total phosphorus on May 15, 1990, according to Orange County Exhibit 12. In a phosphate-limited, oligo-mesotrophic lake such as Lake Down, total phosphates of .03-.04 mg/l require serious attention in terms of what may be the beginning of a significant degradation of ambient water quality standards. The increase in chlorophyll a is consistent with a trend toward enrichment of the lake since the baseline year. The record establishes the role of motorboat traffic in degrading ambient water quality. Bottom sedimentsoften contain many times more phosphorus than is found in the water column. In the case of Lake Down, sampled bottom sediment contained 11 mg/l of phosphorus, or over 200 times the amount contained in the water column. The phosphorus is trapped in the sediment, which, if disturbed, releases the phosphorus back into the water column. Prop dredging may resuspend the sediments and release the phosphorus, as well as destroy bottom vegetation that tends to retain the sediments. Prop wash also may resuspend bottom sediments, even to depths of seven feet beneath the churning prop. Ultimate Findings of Fact Impact of Proposed Dock on Boat Traffic The proposed floating dock would substantially increase use of Lake Down by motorboats. The dock would generate increased boat traffic on Lake Down because of improvements in navigability in the vicinity of the boat ramp and convenience for boaters in picking up and dropping off passengers and walking between the existing parking area and mooring area. The dock, which would be longer than a football field, is designed to moor 15-18 boats simultaneously. At typical current launching rates, the dock would be capable of mooring, at one time, one-quarter to one-half of the boats using the boat ramp on a given day. DER reasons in the Intent to Issue that boat usage would not increase significantly because persons seriously interested in accessing the Butler Chain have overcome the limitations of the present facility. This reasoning ignores persons more casually interested in accessing the Butler Chain. The above-described improvements in navigability and upland safety will increase the frequency of their visits, which presently may be limited to peak days, such as holidays. If the ratio of serious to casual users corresponds roughly to the ratio of typical boat launches to peak boat launches, the number of casual users may outnumber their more earnest counterparts by six to one. The large capacity of the proposed boat dock suggests that Orange County was targeting these more casual boaters. In theory, Special Condition 7 could have a substantial effect upon boaters' access to Lake Down if the ramp and dock were closed when water elevations fell to 97 feet, at which point much of the shoreside of the dock would already be grounding and boats could not approach the east or west ends of the dock without prop dredging. The ambiguity of Special Condition 7, whose meaning remains elusive even after DER and Orange County have had opportunities to explain its operation, precludes assigning the condition any significance, except as a clear invitation to litigate in the event the floating dock were constructed under the subject Intent to Issue. 2. Ambient Water Quality 79. As relevant to this case, the relevant ambientwater quality of Lake Down is the baseline year. The value of chlorophyll a was 50% lower in the year ending March, 1984, than in the year ending with the subject application. Total phosphorus was about the same, as were Secchi depths. Turbidity was 25% less in the latter year, but the lake had acidified slightly. 3. Changes in Water Quality The water quality of Lake Down has deteriorated since it was designated an Outstanding Florida Water. The amount of chlorophyll a has increased, which is consistent with increased levels of nutrients in the water column. By the summer of 1990, phosphate readings were as much as four or five times greater than in the baseline year and had reached a level that threatens water quality in a phosphate-limited lake such as Lake Down. The role of motorboat traffic in disturbing phosphate-laden bottom sediments and destroying bottom vegetation has been discussed above. The dock dredging at lower water elevations, which are frequently encountered, as well as prop dredging immediately adjacent to the dock, would be especially harmful in view of the thick carpet of bog moss present underneath and lakeward of the proposed dock. 4. Effect of Proposed Dock on Water Quality Orange County has failed to provide reasonable assurance that the proposed project would not lower ambient water quality standards with respect to the effects of dock dredging, prop dredging in the immediate vicinity of the dock, and prop wash associated with increased powerboat traffic on the entire lake. Boats presently mooring on the south shore undoubtedly dredge the bottom with their props. However, the effects are less destructive than the prop dredging that would be associated with the proposed dock, even ignoring the effects of dock dredging and prop wash from additional powerboats. First, fewer boats are using the area now than would be with the proposed dock. Second, although possibly once vegetated, the lakebottom adjacent to the shore is sandy without much vegetation or sediment, so resuspension of sediment and release of phosphorus is less of a problem presently than it would be with the use associated with the new dock. The record does not support a finding that the water quality of Lake Down has been adversely affected by the erosion of rubble and fill from the bank used to construct the realigned Conroy-Windermere Road 30 years ago. Concerns about unfiltered stormwater runoff bypassing the vegetated strip by pouring down the eroded paths into the lake are misplaced. Some governmental entity has installed a stormwater system along aconsiderable part of Conroy-Windermere Road, and the outfall is directly into Lake Down shoreside of the west end of the proposed dock. 5. Effect of Proposed Project on Public Interest Orange County has failed to provide reasonable assurance that the proposed project would be clearly in the public interest after balancing the statutory criteria. The proposed project would achieve a net gain in upland safety, although not without exposing pedestrians using the sidewalk to new risks. The project would also increase boater safety by improving navigability in the vicinity of the boat ramp. However, degradations in water quality negatively impact the issues of public health, the property of others, the conservation of fish and wildlife, and fishing or recreational values, which ironically may be threatened as Lake Down risks becoming a victim of its well-deserved popularity. The current condition and relative values of the functions performed by the lakebottom also militate against a finding that the proposed project, which would be permanent in nature, is clearly in the public interest. The factors in the preceding paragraph outweigh the statutory factors in favor of a finding that the project is clearly in the public interest. In addition to the gains in upland safety and navigability, the other favorable factors are that the proposed project would not adversely affect the flow of water or cause harmful erosion or shoaling. A neutral factor isthat the proposed project would not help or harm significant historic and archaeologic resources.
Recommendation Based on the foregoing, it is hereby RECOMMENDED that the Department of Environmental Regulation enter a final order denying the application of the Orange County Parks Department for a dredge and fill permit to construct a floating dock 420 feet by 7 feet.

Orange County did not offer to amend its application, nor even provide a new location for the dock.

Findings Of Fact On January 19, 1984, Applicant applied to DER, pursuant to Sections 253.123 and 403.087, Fla.Stat., and Chapters 17-3 and 17-4, F.A.C., for a permit and water quality certification to construct a 36-slip docking facility in Baker-Carroll Pointe Waterway (the lagoon). While the lagoon is located in Class II waters, the waters are prohibited for shellfish harvesting. On October 31, 1984, DER issued its letter of intent to issue the requested permits. Protestors timely filed a petition for formal administrative proceedings. Protestors' substantial interest will be directly affected by issuance of the subject permit. The proposed facility will be located as close as 50 feet to the main residential building of Protestors, and the proposed docks will be accessed by way of a seawall which is part of Protestors' common area. The Marina The permit sought by the Applicant would allow it to construct a 36- slip docking facility consisting of 615 linear feet of 5 foot wide marginal dock set 6 feet waterward and running parallel to an existing concrete seawall, with three 5 foot by 6 foot access ramps from the seawall to the marginal dock, and eighteen 30 foot by 4 foot finger piers extending waterward of the marginal dock. Nineteen mooring piles are to be installed. Total dock area is to be 5,325 square feet. The facility will be constructed of pressure treated piles and lumber. No fuel facilities are proposed. Applicant proposes to sell the 36 slips to unit owners in the Surf Colony complex, that is Vanderbilt Surf Colony I, Vanderbilt Surf Colony II and Vanderbilt Surf Colony III, and, if and when constructed, Vanderbilt Surf Colony IV and V. Each of the existing buildings contains 65 units. DER's October 31, 1984, letter of intent, proposed to issue the permit subject to the following conditions: Turbidity screens shall be utilized and properly maintained during the permitted construction and shall remain in place until any generated turbidity subsides. The lagoon shall be designated a "No Wake" zone. Markers and/or signs (PVC pipes or piles) shall be erected at the entrance to the shallow cove prohibiting navigation in said area with limits to be approved by the Punta Gorda DER office. No liveaboards shall be allowed at the permitted facility. No boat cleaning, hull maintenance, nor fish cleaning shall be allowed at the permitted facility. Trash receptacles shall be located at approved locations on the dock. The easternmost dock limit shall be lighted at night or equipped with reflective markers to aid navigation. No construction of the project shall take place until appropriate DNR approval is granted for the project per Section 253.77, Florida Statutes. The project shall comply with applicable State Water Quality Standards, namely: 17-3.051 - Minimum Criteria for All Waters at All Times and All Places. 17-3.061 - Surface Waters: General Criteria. 17-3.121 - Criteria - Class III Waters - Recreation, Propagation and Management of Fish and Wildlife: Surface Waters. Applicant has agreed to comply with all conditions established by DER. The Marina Site Baker-Carroll Pointe Waterway (the lagoon) is a partially man made navigable lagoon, with access to Water Turkey Bay which lies to its east. The south side of the lagoon is bulkheaded (along the proposed docking facility site), and the north and west side of the lagoon is composed of dense mangrove forest within the Delnor-Wiggins Pass State Recreation Area (Park). The waters of the proposed project abut and mix with those of the Outstanding Florida Waters (OFW) of the Park. Rule 17-3.041(4)(c), F.A.C. The Park is located on the western and northern shores of the lagoon, and the Park's boundary is located underneath the existing lagoon. The Park has a boat ramp and dock at the mouth of the lagoon. Associated with the ramp are 36 parking spaces for boat trailers. The access channel from Water Turkey Bay varies from 100 to 150 feet wide, the end of the lagoon is approximately 200 feet wide, and the lagoon is approximately 700 feet long. The bulkheaded shoreline has a shallow, 6 foot wide shelf that is covered by a few inches of water during low tide and is colonized by oyster assemblages. Depths increase rapidly from the edge of the shelf to -7 to -8 feet NGVD approximately 40 feet offshore. Depths at the finger piers will be -4.5 to -6.5 NGVD feet. The majority of the central lagoon has uniform depths of -7 to -8 feet NGVD with approximately one foot of silt overlying a firm substrate. Increased depths of -9 to -10 feet NGVD are found in the channel leading from the lagoon to Water Turkey Bay. Channel depths within Water Turkey Bay are -5 feet NGVD or less. Except for a shallow cove at the northwestern extreme of the lagoon, water depths of -5 to -7 feet NGVD are found approximately 30 feet waterward of the mangrove fringe along the western border of the lagoon. In the immediate project site there are no seagrasses or other significant biota. The only productive area within the project site is the shallow six foot wide shelf which parallels the bulkhead and is colonized by oyster assemblages. There are no other significant biota because the area was extensively dredged in the late 1960s or early 1970s. Seagrasses are found in the smaller cove located in the extreme northwest of the lagoon. The western and northern shores of the lagoon are extensively populated by red, black and white mangroves. Aquatic fauna known to inhabit the vicinity, and found in association with the grassbeds in Water Turkey Bay, include lightening whelks, blue crabs, sheepshead minnows, mullet, pin fish, and silver perch. Areas of Concern During construction of the marina elevated turbidity may be expected by disruption of the lagoon sediments caused by installing the facility's pilings. This can, however, be adequately controlled by the use of turbidity curtains during construction. Shading of the benthic environment is a long term impact associated with marinas. While there are presently no seagrasses in the project area, the 6 foot wide shelf which parallels the bulkhead is colonized by oyster assemblages and algae. Since the marginal dock will be placed 6 feet waterward of the seawall, sunlight will be permitted to reach the productive shelf which parallels the seawall. Additionally, since the marginal dock is 5 foot wide, the closest any boat will be to the seawall will be 11 feet. This will result in a buffer zone of 5 feet between the waterward extreme of the 6 foot shelf and any boat moored at the marina. Boats by their very existence and operation present potential negative short term and long term impacts to the environment. Potential damage from existing craft and those which occupy the marina to the seagrass beds in the extreme northwest portion of the lagoon will be eliminated or minimized by the planned installation of markers and/or signs prohibiting navigation in that area. Potential damage from wave action generated by boat operation will be eliminated or minimized by designating and posting the lagoon as a "No Wake" zone. The fueling of boats, hull maintenance and sewage discharge are additional pollution sources associated with marinas. While the proposed marina will have no fueling or maintenance facilities, and while no liveaboards, boat cleaning, hull maintenance, nor fish cleaning will be allowed at the marina, additional conditions must be attached to the permit to eliminate or minimize potential impacts from these potential pollution sources. In addition to the special conditions established by DER, the following special conditions are necessary: All craft docked at the marina shall be prohibited from pumping bilges and sewage into the waters of the lagoon. Ownership and use of the boat slips, or any of the marina facilities, shall be limited to those person(s) who own condominium unit(s) at the Surf Colony complex, to wit: Vanderbilt Surf Colony I, Vanderbilt Surf Colony II, Vanderbilt Surf Colony III, and, if and when constructed, Vanderbilt Surf Colony IV and V. Leasing or any other use of the boat slips, or the marina facility, by any person(s) other than the actual owner thereof shall be prohibited. Since the facility is small, and a full-time dock master is not proposed, limiting ownership and use of the boat slips to owners of condominium units at the Surf Colony complex will provide reasonable assurances that the conditions imposed on the requested permits will be complied with. Prohibiting the pumping of sewage and bilges will provide reasonable assurances that DER standards for bacteriological quality will not be violated. Protestors suggest that oils and greases, including lead found in marine fuels, could cause a degradation of water quality and affect the biota in the area. Protestors presented evidence through Dr. Nancy Nicholson, an expert in marine ecology and marine biology, that oils, greases, and lead could reasonably be expected to be ejected into the water column from boats occupying the marina, and that such pollutants, after entering the sediments, could be expected to enter the food chain. Protestors offered no evidence of the quantities of oil, greases or lead which could be expected to be injected into the water column, or to enter the food chain, other than "they are not large." Petitioner offered no evidence that the oils, greases or lead emitted by the boats occupying the marina would cause or contribute to a degradation of water quality below DER standards, or impact marine resources to such an extent as to be contrary to the public interest. Juxtaposed with the opinion of Protestors' expert is the empirical testimony of DER's witnesses, Terri Kranzer, an expert in water quality and aquatic biology, and Douglas Fry, an expert in dredge and fill impacts on water quality and aquatic biology, that the proposed facility and its operation will not cause or contribute to a degradation of water quality below DER standards and will not impact marine resources to such an extent as to be contrary to the public interest, so long as the Applicant complies with the permitting conditions. Protestors also suggest that turbidity, caused by boats operating from the marina, could cause a degradation of water quality and affect the biota in the area. Protestors' witness, Dr. Nicholson, testified to observing boats increase turbidity within the lagoon. She further performed a Secchi depth test, which measures the distance to which light will penetrate water, in the lagoon area. The background was measured at 42 inches. After the passage of a motorboat through the subject lagoon, the Secchi depth was reduced to 27 inches, and returned to the background level in 2-1/2 to 3 hours. Dr. Nicholson further testified that if the sediments "kicked up" were of an oxygen poor material, that they could scavenge dissolved oxygen from the waters. Protestors offered no evidence, however, which equated the Secchi depth test with the tests and standards established by DER for turbidity and transparency. There was no evidence, assuming turbidity did increase during boat activity, that DER standards for turbidity and transparency would be violated. Further, no evidence was introduced that such turbidity would cause or contribute to a degradation of the dissolved oxygen levels of the lagoon below DER standards. Contrary to the testimony of Dr. Nicholson, Protestors' other witness, William Doherty, a resident of the Surf Colony complex testified that he had operated his own 28 foot boat in the lagoon, and observed other boats operating in the lagoon, and never observed any increased turbidity. Terri Kranzer testified to the same effect. The depth within the lagoon is adequate for navigation, and there should be no increased turbidity caused by boats operating in the lagoon unless they venture into the shallow cove in the northwestern part of the lagoon. Designating the lagoon as a "No Wake" zone, and prohibiting navigation within the shallow cove, would provide reasonable assurances that there would be no increased turbidity associated with the proposed facility or its operation. Finally, Protestors suggest that if the proposed facility is permitted, DER's standard for Biological Integrity, Rule 17-3.111(4), F.A.C., will be violated. Dr. Nicholson conducted a sampling of benthic macroinvertebrates on the bulkhead of the lagoon and on the bulkhead of a nearby yacht basin, in order to calculate a Shannon-Weaver diversity index for both areas. The Shannon-Weaver index for the yacht basin reflected a level of benthic macroinvertebrates of less than 75 percent of that measured in the lagoon. The results of Dr. Nicholson's sampling are not, by her own admission, statistically significant. The lagoon and yacht basic are entirely dissimilar. The lagoon, with its diverse mangrove forests and large opening into Water Turkey Bay flushes well and is an area rich in biology. The yacht basin, on the other hand, is connected to Water Turkey Bay by a small channel and is completely bulkheaded. No valid comparison can be drawn between the lagoon and the yacht basin.
Findings Of Fact By application filed on October 29, 1980, Respondent/Applicant, Harvey B. Ulano, sought the issuance of a permit from Respondent, Department of Environmental Regulation, to authorize the construction of a private pier for mooring a sailboat at 2640 Northwest Collins Cove Road, Stuart, Florida. A copy of the permit application may be found as DER Exhibit 1. The property in question lies on the North Fork of the St. Lucie River in St. Lucie County. The River is classified as a Class III Water of the Sate. Respondent/Applicant's proposal was received by the Department and reviewed for compliance with applicable State water quality standards. The Department concluded that all statutory and rule requirements, criteria, standards and provisions had been met, including those pertaining to biological productivity impact, water quality and navigation. On January 23, 1981, the Department issued its Letter of Intent to Issue a permit with certain conditions therein, including a prohibition against any dredging and filling associated with the project, the required restoration of submerged lands disturbed by construction activities to their original configuration, the employment of an effective means of turbidity control, and a prohibition against live aboards on boats docked at the pier. A copy of the Letter of Intent to Issue may be found as DER Exhibit 2. The applicant intends to construct a 276 foot long pier from an existing concrete retaining wall on his property which fronts the St. Lucie River. The pier will be built at a perpendicular angle with the shoreline and will be 6 feet wide for the first 240 feet, and 12 feet wide for the remainder of its length. There will be no building or boathouse constructed on the dock, nor will pilings extend above the docking until the area where the boats will be tied. The river is approximately 1500 to 2000 feet wide at the proposed project site. However, the depth of the water close to the shoreline is not sufficient to moor larger boats at low tide. Therefore, it is necessary that the length of the pier be 276 feet in order to insure a minimum 3-foot water depth at all times. Applicant's lot is odd-shaped in size. The waterfront footage is approximately 135 feet. Its sides measure approximately 330 feet on the north boundary and 200 feet on the south. The property of Petitioner, Werner Jungmann, adjoins that of Applicant on the south side and also fronts the river. The pier will be constructed on the northwest corner of Ulano's property, which is the most distant point from Jungmann. Because of the odd shapes of the Applicant's and Petitioner's lots, the end of the pier will project slightly within the lakeward extension of Jungmann's property line. However, the design of the pier is such that it should not obstruct or impair the view of the river now enjoyed by the Petitioner. Navigation in the river and existing channel adjacent to the pier will not be affected by the proposed activity. The shallow water depth in the river next to the shoreline already precludes movements by boats close to the shore. The Department has imposed certain conditions upon the construction and future use of the pier (DER Exhibit 2). These conditions, together with the plans submitted by Applicant (DER Exhibit 1), constitute reasonable assurances that the short-term and long-term effects of the proposed activity will not result in violations of the water quality criteria, standards, requirements and provisions of the Florida Administrative Code, and that the proposed activity will not discharge, emit or cause pollution in contravention of Department standards, rules or regulations.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Department of Environmental Regulation issue Respondent/Applicant, Harvey B. Ulano, a permit to construct a private pier for mooring a sailboat on the North Fork, St. Lucie River, subject to those conditions set forth in the Department's Letter of Intent to Issue dated February 23, 1981.

Findings Of Fact The applicant currently operates a 58 slip marina Village at the proposed site, which was constructed under a modified permit from the Department in 1980 by Sunset Realty. Subsequent to that construction, the Petitioner commenced its Marina Village project on uplands adjacent to the existing dock facility and entered into a lease with Sunset Realty to operate the present marina as part of its "Boca Grande Club." The operative portion of the existing marina, that is, where boats are moored and operate, is in water eight feet or greater in depth. The marina provides fuel service at a separate fuel dock as well as electric and telephone service at the individual slips, thus permitting boats using the slips to hook up to on- shore electrical and telephone service. Sewage pump-out equipment is available at the fuel dock and a portable sewage pumping facility is available to be moved to each slip as necessary. Boca Grande Club employs a full time dock master who lives aboard a boat at the existing facility. The facility presently generally serves larger craft, that is, boats generally larger than 25 feet in length and serves some vessels in excess of 60 feet in length. The marina village portion of Boca Grande Club is a condominium, residential development, which is nearly completed and will consist of 48 residential units. A second portion of the Boca Grande Club is located on the Gulf of Mexico some 2,000 feet away from the marina village. The entire project employs slightly more than 100 people. The Petitioner contends that the existing marina of 58 slips is not sufficient to provide adequate dock space for the residents of the development, as well as members of Boca Grande Club. It also contends that the existing dock elevations are such as to make access from small boats to the dock difficult. The number of residents or club members requiring boat slips was not established, nor was it shown that efforts to modify existing dock elevations have been attempted unsuccessfully. In any event, the Petitioner applied to the Department on February 15, 1985, to construct the approximate 3450 square feet of additional dock facility. This would include a "T" shaped structure with an access ramp or walkway extending approximately 189 feet toward the existing channel from the shore. The waterward "T" portion will be 237 feet ~n length. Additionally,. an "L" shaped structure with two sections, each approximately 75 feet in length, would be constructed which would accommodate six boat slips. The "T" shaped dock will accommodate 19 boat slips at its waterward end. The docks proposed will contain ten 3' X 15' finger piers with regard to the "T" shaped dock and two 3' X 15' finger piers attached to the "L" shaped dock. The applicant would install 42 mooring pilings in the bottom of Gasparilla Sound for the mooring of boats using the docks. Thus, the applicant proposes the addition of approximately 25 boat slips with the proposed docks, all of which will be located within Gasparilla Sound, in the Charlotte Harbor Aquatic Preserve, an Outstanding Florida Water (OFW). This is a Class II water body pursuant to Chapter 17-3, Florida Administrative Code, and has also been designated an outstanding Florida water, pursuant to Rule 17-3.041, Florida Administrative Code. The docking facility will be located in an area vegetated by sea grass, including turtle grass and associated algae. The access ramp for the "T" dock would be through a mangrove fringe including red, white and black mangroves. The Department's appraisal recommended denial of the application unless certain modifications to the "T" shaped dock are accomplished, including omitting the "T" shaped docking structure or relocating it to an area without grass beds; that the pilings should be driven into place rather than placed in augured holes; that turbidity screens should be installed and staked around the proposed piling site and that no boats over 25 feet in length or equipped with heads or toilets should be allowed to moor at the docking facility, nor should boats be permitted with people living aboard them. On September 5, 1985, the Respondent issued its Intent to Deny indicating that the project was expected to violate water quality standards and that the construction of the dock and the presence of the moored boats attendant to use of the dock would lower existing water quality in terms of turbidity, biological integrity, bacteriological quality, especially as to fecal coliform and total coliform bacteria and based upon the DER's position that the "T" shaped dock would not clearly be in the public interest in several respects. The Department has no objection and proposes to issue a permit for construction of the smaller, "L" shaped dock. In response to the Intent to Deny, the Petitioner resurveyed the seagrasses in the area and located a site where the water depths sloped to deeper water and seagrasses were sparser. It modified its application, moving the waterward extension of the dock over the deeper water in the less dense seagrasses, but could not move the dock to a location to avoid seagrass since to do so would not allow maneuvering room for larger boats utilizing the existing dock. The applicant agreed to the other suggestions of modification by the Respondent. Thus, the applicant subsequently modified the application to include "bow-in" mooring of boats so as to place boat propellors over the deepest possible waters at the mooring site, as well as raising the central portion of the access ramp leading waterward from the shore, to provide for greater light penetration and less shading of seagrasses, as well as narrowing the dock to five feet in width where it passes through the mangrove fringe, so as to limit alteration of the mangroves at the site to only three trees. The Department continues to take the position that the permit should be denied, however, on the basis that the construction of the dock and the presence of the boats attendant to the dock will lower existing water quality in terms of the above particulars and based upon the DER's evaluation that the "T" shaped dock will not clearly be in the public interest. AMBIENT WATER QUALITY The Petitioner tendered C. W. Sheffield, professional engineer, and Dr. Martin Roessler as experts in the field of water quality and they were accepted without objection. The respondent tendered the expert testimony of Mr. Doug Frye and William Porter, respectively a dredge and fill specialist and supervisor and an environmental specialist with the Shellfish Monitoring Program for the Department of Natural Resources, who were accepted as expert witnesses in the areas of water quality and, with regard to Mr. Porter, the impacts of water quality on shellfish. It was thus established that the ambient water quality in the cove which contains the present marina and where the proposed docking facilities would be is generally good. The water meets all relevant State regulatory standards with the exception of fecal coliform and total coliform bacteriological standards for Class II waters. In that regard, repetitive samples have shown violations of the fecal coliform and total coliform bacteriological standards for Class II waters on a number of occasions. The data relied upon concerning fecal coliform organism levels at the project site was collected and analyzed over approximately a one year period during which time the samples were shown to contain fecal coliform and total coliform bacteria in violative concentrations a number of times. Marinas are known discharge sources for fecal coliform organisms. This is especially true of moored boats in marinas which often have toilets or heads which are illegally flushed into the State waters within the marina. The presence of moored boats with heads are known discharge sources of fecal coliform organisms and the boats utilizing the present marina and the proposed project do, and likely will, have toilets on board, which can be improperly discharged into the waters of the marina. This marina has been established to be a source of discharge of fecal coliform organisms in violation of the relevant standard for Class II waters of the State. There presently exists relatively high levels of fecal coliform organisms ranging up to 50 organisms per 100 milliliters of water in the area of the existing marina. This level of concentration exceeds the regulatory standard for fecal coliform bacteria in the Class II water quality rules. Although Mr. Porter discussed the possibility that high levels of coliform bacteria could be caused by birds or animals depositing fecal material in the water, he established that the likely source of elevated levels of this bacteria was improper operation of heads aboard boats, as pointed out by the fact that samples taken in other areas of the Gasparilla Sound away from marina sites do not exhibit the high coliform levels found on repeated occasions at the subject site. Thus, it has been established that the ambient water quality is within State standards for all parameters with the exception of fecal and total coliform bacteria for Class II waters. The Petitioner contends that Class III water standards are appropriately applied herein inasmuch as the Department placed the Class III standards rather than the Class II standards at issue in its Intent to Deny, albeit mistakenly. There is no question, however, that there are Class II waters of the State involved at this site and the subject area is within the aquatic preserve and outstanding Florida waters. The Petitioner is charged with knowledge of this inasmuch as the aquatic preserve boundaries are delimited in the Department's above-cited, published rule. In preparing and processing its application and electing to proceed with this project, the Petitioner is charged with knowledge that these are Class II waters and that the water quality criteria and considerations applicable to Class II outstanding Florida waters are the appropriate parameters with which it must comply. In any event, this is a de novo proceeding and the Department's initial position with regard to this application is not binding in favor of or to the prejudice of any party to the Section 120.57(1), Florida Statutes proceeding. IMPACT ON BENTHIC COMMUNITY ·9. There is a moderate stand of seagrass at the proposed site of the "T" portion of the dock or waterward end of the dock, with dense seagrass beds existing toward the shore, over which the narrower walkway portion of the dock will traverse. Seagrass beds are an especially productive marine community which contribute greatly to the biological diversity in surrounding waters because of their important function in the marine food chain. That function is involved with the seagrasses production of detrital matter consisting of seeds and vegetative material which marine organisms feed upon and upon which organisms larger fish, including commercial and sport fish species, feed upon. Potential adverse impacts caused by a project of this type on the Benthic Community at the project site and especially the seagrass beds involve the potential shading of seagrasses caused by the location of the dock over them, as well as the mooring of boats over them which shading retards or eliminates photosynthesis, which ultimately can kill the seagrass and thus reduce marine productivity in the area. The concentration of boats at such a mooring site as the end of this "T" dock will concentrate the effects of prop scouring, washing and prop dredging, which will have a destructive effect on seagrasses as well as the settling out of sediment from propellor wash or disturbance of the bottom on the seagrasses which can ultimately smother them as well as other marine life forms. In discussing these considerations, it should be pointed out that the "T" portion of the dock would be oriented in a general north-south direction which causes the shadow of the dock to move rapidly as the sun passes overhead in a general east to west direction. This would tend to minimize the effect of shading on the seagrass of the dock itself, particularly with regard to the approach ramp portion of the dock which is relatively narrow. That portion of the dock extending toward the shore runs in an east to west direction and would not exhibit the same rapidly moving shadow, but the central portion of the approach walkway has been elevated to such an extent that light reaching under the dock from both sides will be sufficient to allow photosynthesis of the seagrasses under the dock, although not for as long a period of the day nor at the same rate as would be the case if the dock were not present. The Petitioner asserts that its voluntary relocation of the "T" shaped portion of the dock from an area of dense sea grass to a moderately populated sea grass bed plus the proposed bow-in mooring of boats so as to alleviate propellor damage to the seagrass, together with its view concerning the prevailing water depth at the end of the dock, will serve to prevent damage to the seagrass at the end of the "T" dock where the boats will be moored. It has been shown, however, that the mooring of boats whether bow-in or otherwise will still create a significant amount of shading of the bottom which, together with the shading caused by the "T" dock as well as the associated finger piers will retard or prevent photosynthesis to some extent, especially where boats are moored for days at a time without moving. This will significantly reduce the marine productivity attributable to the seagrass by retarding its natural function or, in some cases, killing it with the resultant loss of the detrital production as well as carbon production, the former being crucial to the proper functioning of the marine food chain in the area. If the seagrass is damaged or extinguished by the shading effect, prop scouring and washing, and/or settlement of turbidity on the seagrass, or a combination of these factors, not only will its productivity be lost, but the biological diversity of marine life in the area will be reduced as it relates to those vertebrate and invertebrate marine animals which depend on seagrass as a food source either directly or indirectly. Dr. Roessler, for the Petitioner, opined that the attached biological communities or "fouling" organisms such as barnacles which would form on the dock pilings, if they were installed, would provide habitat for marine life and invertebrates and thus enhance the biological diversity of the area. These fouling organisms which attach to pilings, however, represent a very narrow portion of the potential marine biological diversity of life forms in an area such as this. Their advent on the pilings, should the pilings be installed, would not mitigate for the loss of important marine habitat and resultant species diversity that elimination of this portion of the seagrass beds would pose. Thus, reasonable assurances have not been established that significant adverse impact to the Benthic Community in the form of damage or elimination of the seagrass beds and their dependent biota will not occur due to shading and propellor scouring, dredging and washing occasioned by the installation of the docking facility. Respondent's expert witnesses Sheftal, Barth, and Dentzau uniformly expressed a concern for propellor scarring, dredging and prop washing of the seagrass beds caused by an improper operation of boats in the project area where water is too shallow over the grass beds to protect them from the resultant propellor damage. In this regard, the Petitioner's own experiments with actual boats indicated that approximately one to 1 1/2 feet of water will remain between the bottom of the sound and the boat propellors at the end of the "T" dock for the general type and size of boats which will use the dock, even assuming that the boats are moored bow inward, thus taking maximum advantage of the deepest water possible under the propellors when a boat engine is started. Respondent's witness Dentzau performed a test with a 21 foot boat with an approximately 100 horsepower outboard engine running it in both forward and reverse at the "T" end of the dock. He was able to readily generate a "plume" of turbidity consisting of sand and other bottom material suspended in the water by the scouring action of the propellor. Although it was demonstrated for water quality parameter considerations that this turbidity plume did not violate the water quality standards for turbidity, it obviously shows that over time the turbidity suspended by boat propellors will settle on the seagrasses and other bottom dwelling biota to their detriment and, more immediately important, demonstrates that prop washing and scouring will occur by boats even if moored bow-in at the presently proposed site of the "T" shaped portion of the dock. The Petitioner proposes by the configuration of its "L" shaped dock in conjunction with the IT" shaped dock, as well as with buoy lines, to keep boat traffic away from the dense grass beds surrounding the proposed dock site and over which the walkway will extend. The Petitioner will mark the entrance channel to the marina itself to keep boats from straying over adjacent grass beds. It has not been demonstrated, however, what steps can be taken to effectively prevent boats from approaching the side of the proposed dock around the ends of the buoy lines and over the dense grass beds toward prohibitively shallow water where prop scouring and scarring will occur. Further, although the Petitioner will mark the entrance channel to the marina itself to keep boats from straying over adjacent dense grass beds, the likelihood of propellor damage to the grass beds in the vicinity of the end of the "T" dock has been exacerbated by the concentration of boat traffic which will result by installation of that dock, over waters at the mooring site which are of insufficient depth to protect the grass bed at that location from scouring and washing from boat propellors. In view of these reasons, significant adverse impacts to the Benthic Communities and especially to the grass beds themselves will result by installation of the docking facility at the site proposed, primarily because of insufficient water depth for safe operation of boats in relation to the well-being of the grass beds in the vicinity of the end of the dock and because of the shading which will result by installation of the "T" shaped portion of the dock in conjunction with the boats to be moored to it and the finger piers between the boat slips attached to it. WATER QUALITY The Respondent, through its water quality expert witness, Doug Frye, expressed the concern that the proposed project would violate Rule 17-3.051, Florida Administrative Code, which requires that the State's waters be free from pollutants above a certain level measured by various accepted and codified scientific methods of measurement. In this regard, the primary concern of the Department is bacteriological quality as well as turbidity resulting from boat operation. The turbidity standards contained in the above Rule provides that State waters not exceed 29 nephelometric turbidity units above the natural background level. The Respondent contends that this level will be exceeded as a result of operation of boats in the vicinity of the dock. The Petitioner, however, presented a soils analysis and silt settling study which showed that bottom materials in the area involved consist of sand, with some finely pulverized shell and that this material settles very rapidly after being disturbed with little silt remaining in suspension a significant period of time after the disturbance. This is primarily because the level of organics in the bottom substrate is very low at this site. In this connection, the Petitioner's expert witness, Mr. Sheffield, anchored a 16 foot boat with a 40 horsepower outboard motor in the docking area of the proposed project. He operated the boat at 1,000 RPM for an extended period of time while measuring the resultant turbidity. The results of his measurements showed turbidity to be in the range of 5-11 NTUs. The Respondent's witnesses, however, operated a larger 21 foot boat at the location of the "T" shaped portion of the dock maneuvering it back and forth with a fairly large outboard motor in the 100 horsepower class, which might be presumed to be typical of the boats which will be using the proposed facility. The maneuvering of the boat with the larger engine in this shallow water created a clearly visible plume of turbidity shown by photographs introduced into evidence by the Respondent. In fact, however, although the turbidity plume was clearly visible, the Respondent's own direct measurement of turbidity taken from within the plume immediately after it was generated was 23.8 NTUs, still below the State standards for violations as to turbidity. The existing marina facility has a fuel dock and has adopted a fuel spill contingency plan. There will be no fueling of boats nor fuel kept at the proposed docks. Nevertheless, marinas were established to be a known source of discharge of oils and greases and the presence of more boats utilizing all the dock facilities, especially during fueling and maintenance procedures, will result in additional oils and greases being deposited in the water. Even if there is no fueling facility planned for the proposed docks, the additional boats represented by the 25 additional slips sought to be approved will have to be fueled and likely at the existing facility. This will heighten the risk of fuel, oil and grease spills. In this regard, it must be remembered that the present marina and the proposed docking facilities are in outstanding Florida waters in which no degradation of ambient water quality is permitted. In this context then, the Petitioner/Applicant has, not provided reasonable assurances that pollution levels for oils and greases will not increase as a result of the potential addition of 25 boats to this marina facility. A substantial issue has been raised in this proceeding concerning water quality as it relates to the bacteriological standard. It has been established that this marina is presently a source of discharge of fecal coliform organisms which frequently are present in sufficient concentrations so as to violate the standard for that organism for Class II waters. Fecal coliform bacteria are accumulated in the bodies of shellfish. The shellfish themselves are not harmed, but contaminated shellfish can accumulate concentrations of as much as 100 times the ambient fecal coliform bacterial levels present in the waters they inhabit. Fecal coliform bacteria can cause extreme illness in human beings, sometimes even paralysis and death. Fecal coliform bacteria in State waters results from the deposition therein of human or animal waste. The Petitioner maintains a sewage pumpout station located at its fuel dock with a direct connection to its sanitary upland sewer system, as well as a portable sewage pump that can be moved to each boat slip for pumping out of toilets or "heads" on boats. Upland fish cleaning stations will additionally be provided with the proposed docks so as to prevent refuse from fish cleaning activities being deposited into the waters of the cove. The fact remains, however, that there presently exist high levels of fecal coliform organisms in the waters of the cove at the marina site, in the above noted violative concentrations on repetitive occasions. The presence of boats moored in the marina with "heads" aboard are a known discharge source of fecal coliform organisms. The Petitioner proposes to restrict boats using the facility to those boats without marine heads aboard or requiring those with heads to keep them locked or otherwise not discharge them into the waters of the marina. If boats utilizing the marina have toilets aboard, however, there is a substantial likelihood that at some point those toilets will be discharged into the waters of the cove before any of the Petitioner's monitoring personnel are aware of it. The problem is thus one of enforcement. In this regard, it is established that even with the sewage pumpout station and the portable sewage pumpout device, that there are a number of "live-aboard" boats with marine heads in the marina at the present time and customarily. This has caused the above found violations of fecal coliform, Class II water standards. Although the Petitioner proposes to restrict boats at the proposed docking facility to those less than 25 feet in length and to establish a monitoring program by the marina management personnel to assure that the boats with heads only contain heads approved by Coast Guard regulation, reasonable assurances have still not been established that the enforcement plan proposed can be effective in ensuring that no marine heads or other sources of coliform bacteria will be discharged into the waters of the cove at the project site. The plan proposed by the Petitioner simply did not ensure that boats having marine heads will not use the marina and that those persons using boats so equipped will not, on some occasions, discharge the heads into the waters of the marina at the project site nor that spills will not result in the sewage pumping-out process. The Respondent's expert witness, Mr. Porter, confirmed that most fishing boats of the open "center console" variety of 25 feet length or less do not contain marine heads, nevertheless, he established that in his experience monitoring marinas of this sort, the restrictions against marine heads of the non-approved variety and the attempted restriction against boats discharging the contents of their heads into the waters of the marina cannot be effectively enforced nor was it established that fishing boats without marine heads will be the only type of boat to use the proposed docking facilities. Accordingly, the waters of the cove at the marina site and project site are in frequent violation of the fecal coliform and total coliform parameter for Class II waters and reasonable assurances have not been provided that the fecal coliform bacterial levels will not increase as a result of the installation and operation of the proposed facility with its attendant boats. Because of the likelihood of shellfish contamination by fecal coliform bacterial levels which will likely increase if the proposed project is constructed and operated, together with the loss of marine habitat and productivity posed by the harm likely to result to the seagrass beds in the vicinity of the proposed facility due to attendant boat operation, it has been shown that the water quality parameter for biological integrity in these Outstanding Florida Waters will likely be degraded. The "Diversity Index" of marine microinvertebrates in the area of the affected seagrass beds will likely be reduced below 75 percent of background levels. Therefore, in the context discussed above, the proposed construction and operation of the 25-slip marina facility with the "T" dock will lower ambient water quality in these outstanding Florida waters and will result in violations of State water quality standards for Class II waters in the above particulars. SHELLFISH HARVESTING Mr. William Porter of the Department of Natural Resources Bureau of Shellfish Sanitation established that the cove where the project would be located is closed to the taking of shellfish as a result of the contamination or potential for contamination of shellfish by coliform bacteria contained in fecal material. His Department's water quality sampling confirmed the elevated levels of fecal coliform bacteria in the cove on repetitive occasions. This elevated level of coliform organisms was shown to result from improper operation of marine toilets upon vessels using the marina at the present time. Because of the potential for contamination from vessels discharging fecal material, Mr. Porter established that the Department would likely close an area 50 percent larger than the present shellfish harvest closure area as a result of a 50 percent increase in the number of boats capable of using the marina if the proposed project is built. Mr. Porter acknowledges that if it could be assured that boats using the marina did not contain heads, the increased area of closure might be lessened after this project were built. He also established as pointed out above that such restrictions on boats containing heads from using the proposed boat slip is very difficult to enforce. Even with the present central sewage pumpout facilities and portable pumpout equipment at the existing marina, the marina still has failed to comply with fecal and total coliform standards for Class II waters on a repetitive basis. The management of the present marina has allowed live-aboard boats at the marina even though it has posted warning signs against boat owners discharging toilets in the cove waters. Mr. Porter also acknowledged that the Boca Grande North Marina, owned by Gasparilla Pass, Inc., was recently permitted by the DER and constructed and has not yet resulted in the Department's closing an additional area to the taking of shellfish. The area the marina is situated in, however, is only "conditionally approved" for the taking of shellfish, meaning that it is subject to closer monitoring by the DNR with a view toward the possible necessity of closing waters in the area of that marina. It was not established, however, how the fecal coliform or total coliform levels in the waters adjacent to that marina compare to the existing marina or the site of the proposed docking facilities at the existing marina, nor what conditions might prevail which would render that other marina a comparable site to -be used as a relevant demonstration of what conditions might be expected at the present marina if the proposed project were built and operated. Thus it has been shown that even though the Petitioner proposes limiting the size of boats at the proposed facility and closely inspecting and regulating any marine heads on boats using the facility to make sure they comply with Coast Guard regulations, it has not been demonstrated that the additional deposition of fecal coliform bacteria in the waters often the cove will be adequately prevented by the proposed enforcement measures. It is thus reasonably likely that the construction of the proposed project will lead to the closing of an additional area of water which is presently approved for shellfish harvesting. The closure of shellfish harvesting in waters is contrary to the public interest in terms of recreational values, fishing and marine productivity and others of the seven public interest criteria quoted below. Further, the contamination of shellfish, which can cause severe illness or even death in human beings, is clearly contrary to the public interest and there is a substantial likelihood that shellfish contamination is already occurring in the area due to the characteristic of shellfish by which they accumulate or store fecal coliform organisms to reach injurious levels for human consumption even though the shellfish themselves appear to be healthy. The area of the proposed project is extensively used for commercial and recreational shellfish harvesting at the present time, outside the immediate closed waters of the marina within the cove. PUBLIC INTEREST Section 403.918(2) (a) (1-7) requires that the Petitioner provide reasonable assurances that the proposed project will be clearly in the public interest. The public interest considerations of those seven criteria concern whether the project will adversely affect public health, safety or welfare or property of others: whether it will adversely affect conservation of fish and wildlife or their habitats; whether it will adversely affect the fishing or recreational values or marine productivity in the project vicinity; whether it will be of a temporary or permanent nature; and the effect on the current condition and relative value of functions reformed by areas affected by the project. Although Petitioner's witness, Dr. Roessler, related that the attached fouling communities, such as barnacles, which would form on the proposed docks and pilings would increase the diversity of marine habitat available, that will not offset the loss of marine habitat occasioned by the increasingly detrimental effect imposed by the project and the operation of it on the seagrass beds, in the manner discussed above. The fouling communities expected by Dr. Roessler to occur on the pilings to be installed, will not provide, nor replace the value of, the detritus (seeds and leaves) produced by the seagrass which would be lost, which is an important food source for marine organisms in the upper portion of the food chain in the area, some of which organisms include fish and have a high recreational value and commercial value. The importance of detrital production by the seagrass beds outweigh the value of the addition of the fouling communities on the pilings. In fact, the total diversity of marine species actually might decline even though the fouling organisms would be added with the installation of the pilings, once the harmful effects on the seagrass beds begin to occur after installation and operation of the proposed facility and over the life of the marina. Thus, in this regard, the project is contrary to the public interest and certainly not clearly in the public interest. Additionally, there is a substantial likelihood that shellfish may be contaminated which, in turn, will have an adverse effect on the public health, safety and welfare. The harvesting of shellfish has a substantial recreational and commercial value and is an important aspect of the marine productivity in the vicinity of the project. The heightened coliform bacteria production caused by the resultant expansion of the marina will adversely affect fishing and recreational values and marine productivity and will degrade the current condition and relative values of the functions performed by the marine habitat in the vicinity of the proposed dock. Finally, there is no question that the project will be of a permanent nature. The various detrimental effects on the public interest consideration found herein are rendered more critical by the fact that there is no truly redeeming public purpose or use for this project. This will be essentially a private docking facility designed to serve the residents of the applicant's attendant real estate development. The upland development is a condominium development and the slips will be owned by the condominium owners and not open to the general public, although the Petitioner did make vague reference to an idea that some slips might be rented to members of the public. This was not established to be the case and, in any event, the primary purpose of the boat slips is to enhance the desirability of the upland development. Although the Petitioner emphasizes that the advent of the additional slips might help attract as much as $1,000,000 additional revenue to the Boca Grande area by assisting the applicant in hosting the Annual Tarpon Release Fishing Tournament, it is also true that any development in a coastal area will likely represent some economic benefit to that area, but there is also a substantial economic and recreational benefit to maintaining the outstanding Florida waters involved in an undegraded condition and maintaining the present Class II, approved shellfish harvesting area unimpaired. Thus, although the proposed docks might be used for sponsorship of the subject fishing tournament and it can be said that that would enhance fishing and recreational value to some extent, it was not established that the tournament will not occur and that the extra revenue and enhancement of fishing and recreational value it will generate will not occur in the Boca Grande area anyway. The potential detrimental effects of the proposed project, delineated above, will also decrease fishing and recreational value over many years and for the life of this project in terms of harm to the marine habitat occasioned by the constant deposition of oils, greases and fuel and coliform bacteria in the Class II waters involved, as well as the other detrimental aspects of the project discussed above. It has not been established that the economic benefits of the fishing tournament and the addition of the boat slips will not occur but for the installation of this proposed docking facility. Although it may help relieve a shortage of marina slips in the area, it was not shown that this is the only alternative to relief of that shortage. ALTERATION OF MANGROVES The original site for the access ramp or walkway to the "T" shaped portion of the dock was selected through an on site inspection conducted in part by Respondent's witness, Andrew Barth. The mangrove area is less dense at the site of the walkway's penetration of the mangrove belt than surrounding mangrove areas. Petitioner's witness, Dr. Roessler, has participated in many studies involving mangroves in South Florida. He identified each tree within the proposed dock pathway. Through narrowing of the dock walkway to five feet and the relocation agreed upon by the Petitioner and Mr. Barth, it has been established that only three mangrove trees will be removed by the construction of the dock. Thus, there will be no substantial alteration or degradation of the mangrove fringe area at the project site. DOCK CONSTRUCTION Mr. C. W. Sheffield was accepted as an expert witness in the field of marine engineering. He established that the pilings will be installed using a 6 to 8 inch chisel point driven into the bottom of the sound with an air hammer. There will be no augering or other means of excavation used which would generate a substantial amount of turbidity. The air hammer will result in compaction of sediments by forces radiating out from the piling as it is driven, with the counteracting sheer force caused by the piling installation causing a slight bulging in the bottom around each piling, but nothing more. There will be no significant movement of sediment in the water column. The construction of the dock will take place moving from the land waterward, utilizing equipment mounted on the dock. Thus, construction barges will not be required to come into the shallow grass bed area with the potential for its damage. Small barges would be used in the deeper waterward portions of the project to install the mooring pilings off-shore from the end of the "T" dock. Turbidity curtains will be used during all construction, surrounding all phases of the construction work. In Mr. Sheffield's experience, such measures have resulted in no violation of the State turbidity standards at other similar projects, and are not likely to with this one. CUMULATIVE IMPACT A number of permits have been issued by the Department for docking facilities to the north of this proposal and other facilities are already in existence. Dr. Roessler opined that the geographic location of these, as well as that of this project, in light of the numerous inlets and high degree of tidal flushing and exchange through the inlets, will not result in any adverse cumulative impact occasioned by the addition of the proposed dock with 25 slips to those already existing in the Sound. It is noteworthy that, with regard to the potential this project poses for damage to the seagrass beds and for heightened production of fecal coliform bacteria, with the environmental damage attendant thereto, no proof was offered by either party concerning those considerations or effects to the extent that they might or might not exist at other marinas or docking facilities in the Gasparilla Sound area. There has been no proof to establish any cumulative impact.
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the testimony and evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is, therefore RECOMMENDED that a Final Order be entered denying the subject permit application, except for that portion seeking authorization for the "L" shaped dock and six boat slips attendant thereto, which should be granted with the agreed-upon conditions and restrictions contained in the above Findings of Fact.

The Issue The issue is whether Bayou Arbors, Inc. (Arbors), is entitled to a dredge and fill permit to construct docks in DeBary Bayou, Volusia County, Florida.
Findings Of Fact On January 8, 1986, DER received an application from Arboretum, a predecessor in interest of Arbors, to construct 12,758 square feet of docks in DeBary Bayou to provide ninety eight (98) boat slips, and to dredge 2,509 cubic yards of shoreline material from DeBary Bayou in areas within DER's jurisdiction under the proposed boat docks, and to place approximately 800 linear feet of concrete riprap along the shoreline after it was dredged. Following the initial application review process, which included on- site evaluations by several DER biologists, on April 14, 1986, DER prepared a Biological and Water Quality Assessment in which DER's staff recommended that the project be modified to delete the dredging, allowing the littoral zone to remain intact. On April 24, 1986, DER forwarded its Biological and Water Quality Assessment to Mr. Charles Gray, the property owner. In response to DER's recommendations, the Applicant submitted, and on April 30, 1986, DER received, a revised Application which deleted the originally-proposed shoreline dredging of 2,509 cubic yards of material as well as the placing of 800 linear feet of concrete riprap. This Application was submitted by Mr. Duy Dao, a Professional Engineer registered in the State of Florida. This Application proposed constructing approximately 17,000 square feet of docking facilities, providing ninety-eight boat slips, along approximately 2,580 linear feet of shoreline adjacent to twenty-four acres of uplands owned by the Applicant. The original and the revised drawings omitted a vertical scale from the cross-section drawings of the project. This omission gave the impression that the shoreline bank of DeBary Bayou was steeper than it actually is and that the water depths in DeBary Bayou adjacent to the north shoreline are deeper than they actually are. However, DER's biologists were on-site four times between February 25, 1986, and May 19, 1986. They observed the existing slope of the DeBary Bayou shoreline and the existing depths in DeBary Bayou, and the on-site observations negated the effect of the omission in the drawings. The omission in the drawings did not affect DER's evaluation of the project. On May 23, 1986, DER issued its Intent to Issue and Draft Permit No. 64-114399-4 to Arboretum. The Intent to Issue and the Draft Permit include the following Specific Conditions: Further construction on the Applicant's property along the DeBary Bayou shall be limited to uplands; Issuance of this permit does not infer the issuance of a permit for dredging in the Bayou at a future date, should an application for dredging be submitted; A deed restriction shall be placed on the condominium limiting boats moored at the facility to seventeen feet or less. A copy of the deed restriction shall be submitted to the Department within sixty days of issuance of this permit; There shall be no "wet" (on-board) repair of boats or motors at this facility; All boats moored at the dock shall be for the use of residents of the condominium only. Public use of the dock or rental or sale of mooring slips to non-residents of the condominium is prohibited; Manatee warning signs shall be placed at 100 foot intervals along the length of the dock(s); Turbidity shall be controlled during construction (by the use of siltation barriers) to prevent violations of Rule 17-3.061(2)(r), Florida Administrative Code. On June 29, 1987, Volusia County, DER and Arboretum entered into a "Joint Stipulation for Settlement" wherein Arboretum agreed not to construct more than twenty-six docks accommodating more than fifty-two boat slips along Arboretum's DeBary Bayou frontage of 2,580 feet. Furthermore, Arboretum agreed that it would modify the configuration and the design of the boat slips and the location of the boat docks; that it would post Slow Speed, No Wake zone signs and manatee education signs along DeBary Bayou from the 1-4 bridge west to a point 100 feet west of the western boundary of Arboretum's boat docks; and that as mitigation for the removal of vegetation from the littoral zone where the boat slips would be constructed, Arboretum would plant wetland hardwood trees. In addition to the Joint Stipulation for Settlement, on June 14, 1987, the property owners, Charles Gray and Sandra Gray, as part of their agreement with Volusia County, executed a "Declaration of Covenants, Conditions, and Restrictions" to which the Joint Stipulation for Settlement was attached as an exhibit. Said Declaration of Covenants, Conditions, and Restrictions, reiterated the Joint Stipulation's limitation of construction of boat docks in DeBary Bayou and further provided that said boat docks would not be constructed at the Arboretum project site in DeBary Bayou unless and until certain maintenance dredging set forth in Article II of the Declaration of Covenants, Conditions, and Restrictions occurred. Furthermore, Article III of said Declaration of Covenants, Conditions and Restrictions set forth certain prohibitions regarding constructing boat ramps on the Arboretum property and docking or storing boats along the DeBary Bayou shoreline except at the site of the proposed docks. In 1969, an artificial channel was excavated in DeBary Bayou adjacent to the north shoreline of DeBary Bayou by a dragline operating along the shoreline. At present, said channel has been partially filled by organic sediments originating in DeBary Bayou. There exists in Section 403.813(2)(f), Florida Statutes, an exemption from the DER's permitting requirements for the performance of maintenance dredging of existing man-made channels where the maintenance dredging complies with the statutory provisions and with the regulatory provisions found in Florida Administrative Code Rule 17-4.040(9)(d). The dragline excavation work performed in DeBary Bayou in 1969 created a structure which conforms to the definition of "channel" provided in Section 403.803(3), Florida Statutes. The maintenance dredging required by the Declaration of Covenants, Conditions, and Restrictions is to be performed by suction vacuuming of the silt sediment, from the 1969 channel and that dredged material is to be placed on Arbors' upland property at the project site. This maintenance dredging differs from the dredging originally proposed by the applicant in its application submitted in January 1986. The dredging originally proposed, which DER recommended against, was to be performed by back hoes and drag-lines which would have cut into the north shoreline of DeBary Bayou and would have affected the littoral zone along the project shoreline. The average water level in Lake Monroe and DeBary Bayou is approximately 1.8 feet above mean sea level. On April 18, 1987, transact studies in DeBary Bayou showed water levels at 3.2 feet above mean sea level and that water depths in DeBary Bayou to a hard sand/fragmented shell bottom ranged from approximately one foot along the south shoreline to approximately nine feet in deep areas in the former channel. The average depth of the channel is five feet below mean sea level. The water depth in DeBary Bayou ranges from approximately one to three feet. At times of average water levels, one to three feet of silt or unconsolidated sediment overburden covers the natural hard sand/shell bottom of DeBary Bayou. This silt and sediment overburden is composed of organic material and is easily disturbed. When it is disturbed, it raises levels of turbidity, although there was no evidence presented that the turbidity would violate state water quality standards. This silt and sediment overburden has been deposited at a faster rate than it would normally be deposited under natural conditions because of the Army Corps of Engineers' herbicidal spraying of floating plants in DeBary Bayou. As this silt and sediment overburden decomposes, it takes oxygen from the water. The presence of a strong odor of hydrogen sulfide indicates that the oxygen demand created by the sediment is greater than the available supply of oxygen at the sediment-water interface. This unconsolidated silt and sediment overburden does not appear to harbor either submerged vegetation or significant macroinvertebrate populations. The Shannon/Weaver diversity index of benthic macroinvertebrates at four locations in DeBary Bayou indicated lowest diversity at the project site and highest diversity at the 1-4 overpass, where a small patch of eel grass is growing. Removal of this silt and sediment overburden from the 1969 channel will enhance the system, enabling a hard bottom to be established, with a probability of subsequent establishment of a diversity of submerged macrophytes. Removal of the silt and sediment overburden from the 1969 channel will restore the natural hard sand/fragmented shell bottom in that area of DeBary Bayou. It is unlikely that boat traffic in the restored channel will cause turbidity which will violate state water quality standards. Removal of this silt and sediment overburden will improve water quality in DeBary Bayou by removing a source of oxygen demand. Removal of this silt and sediment overburden will create a better fish habitat by exposing some of the natural bottom of DeBary Bayou. Fish are unable to spawn in the unstable silt and sediment. Removal of this silt and sediment overburden will increase the depth of water in DeBary Bayou channel to between four to six feet. The maintenance dredging, required by the Declaration of Covenants, Conditions, and Restrictions, is limited by statute to the channel which was excavated in 1969. Therefore, a continuous channel will not be maintained from the project site eastward to Lake Monroe. At present, a sandbar exists at the confluence of DeBary Bayou and Lake Monroe. During low water, this sandbar restricts navigation into and out of DeBary Bayou to small craft. At present, boats can and do travel on DeBary Bayou for fishing and for other water-related recreational activities. However, due to water level fluctuations, boating on DeBary Bayou is easier during higher water periods. During lower water periods, navigation into and out of DeBary Bayou is still possible, but boaters must proceed using common sense and caution. The United States Fish and Wildlife Service (FWS) has no evidence that manatees presently use or have ever used DeBary Bayou. Adult manatees have an average girth of approximately three (3) feet. Without a continuous channel open to Lake Monroe, manatees are not likely to go up DeBary Bayou. Since the water at the sandbar at the mouth of DeBary Bayou at its confluence with Lake Monroe is generally less than three feet deep throughout the year, it is likely that these shallow waters will deter manatees from entering DeBary Bayou. DeBary Bayou is a spring-fed run from a spring a substantial distance upstream. The sheetflow of the spring water follows a circuitous route through marsh areas prior to reaching the area of this project. The proposed site is just west of the 1-4 overpass and Lake Monroe. The FWS's data show that the St. Johns River in Volusia County has an extremely low documented manatee mortality rate resulting from boat/barge collisions. Generally, boats greater than 23 feet long are more likely to kill manatees outright than smaller boats are. In marinas, manatees are very rarely killed by collisions with boats. Manatees and marinas are highly compatible. On August 1, 1986, the FWS issued a "no-jeopardy" opinion regarding Arbors' project. In this letter, the FWS stated that Arbors' project was not likely to jeopardize the continued existence of the manatee or to adversely modify the manatee's critical habitat. In the year since the FWS issued its no-jeopardy opinion, no manatee mortalities resulting from boat-barge collisions have been documented in the St. Johns River in Volusia County. The FWS recommended one boat slip per one hundred linear feet of waterfront, or twenty-six boat slips for the project. A single-family residence which would be entitled to one pier could berth an unlimited number of boats at that single pier. The FWS would have no control over the number of boats using that single pier. Arbors' project calls for twenty-six piers. The FWS's evaluation of Arbors' project is exactly the same as that agency's evaluation of any other marina project anywhere in areas designated as critical manatee habitat. All of the St. Johns River in Volusia County, Florida, is designated as critical manatee habitat. On July 16, 1986, after issuance of its Intent to Issue, DER received comments from the Florida Department of Natural Resources regarding Arbors' project and its potential impact on manatees. DER considered the possibility of boat/manatee collisions and had specifically considered this issue. DER did not agree with the broad and general concerns expressed by the Department of Natural Resources, and DER's rules have not adopted a specific requirement regarding a ratio between the length of a project's shoreline and the number of permittable boat slips. On July 16, 1986, the Department received a letter from the FWS concerning fisheries issues and navigation. This FWS letter was received after issuance of DER's Intent to Issue. Although DER considered these comments, DER disagreed with the FWS's recommendations regarding these issues. Water quality sampling and analysis showed that at present, there are no violations of DER's Class III water quality standard in DeBary Bayou, except for the dissolved oxygen criterion on some occasions during early-morning hours, and that result is to be expected. It is further not expected that there will be any water quality violations after the project is completed. If the work areas affected by driving piles to build floating docks and the work area around the maintenance dredging of the DeBary Bayou channel are contained within turbidity barriers, as required by general and specific conditions of the DER's proposed Draft Permit, it is anticipated that no violations of the Class III turbidity criterion will occur during construction of Arbors' project. By maintenance dredging the former DeBary Bayou channel, Arbors will remove the silt and sediment overburden from the channel and restore a deep (four to five feet below mean sea level) channel having a hard sand/fragmented shell bottom. Arbors' dock will be restricted to small boats whose operation in the deep channel will be unlikely to re-suspend silt and sediment and cause violations of the Class III turbidity criterion. Additionally, it is unlikely that any turbidity which is created by turbulence from boat propellers in a designated "No Wake, Slow Speed" zone will violate the Class III turbidity criterion. Although the entire project will be enhanced by the proposed maintenance dredging, such dredging is not a part of the permit application. From the evidence it appears that the project is permittable without the dredging. Although Arbors' project will result in the addition of some oils and greases associated with outboard motors to DeBary Bayou, the addition is not expected to result in violations of the Class III water quality standards. Additionally, release of heavy metals from anti-fouling paints should be minimal, and that release can be further controlled by specifically prohibiting over-water repair of boats and motors. Some addition of phosphorous to the waters of DeBary Bayou is anticipated due to use of phosphate-based detergents for washing boats. Additionally, minimal amounts of phosphorous may be added to DeBary Bayou from re-suspension of organic silts by turbulence from boat propellers. However, DER has no standards for phosphorous in fresh waters, and the minimal additional amounts of phosphorous expected from these sources are not anticipated to violate DER's general nutrient rule. Operation of boats at Arbors' proposed boat docks will cause no water quality problems which would not be caused by operation of boats at any other marina anywhere in Lake Monroe or anywhere else in the State of Florida. While WVC's expert, Robert Bullard, testified that Arbors' proposed boat docks could potentially cause violation of DER's Class III water quality criteria for turbidity, oils and greases, heavy metals and phosphorous, he was unable to testify that Arbors' project actually would cause such violation. His testimony in this regard was speculative and is not given great weight. No other WVC expert testified that Arbors' project was likely to cause violation of any criteria of DER's Class III water quality standards. It is anticipated that the shade cast by the boat docks will not have an adverse affect on water quality. Additionally, DeBary Bayou is a clear, spring-fed water body open to direct sunlight. The boat docks will cast shade which will enhance fish habitat. The proposed docks will not threaten any production of fish or invertebrate organisms. The mitigation plan proposed by the applicant and accepted by Volusia County and DER requires planting wetland hardwood tree species. These trees will certainly assist in stabilizing the bank of DeBary Bayou and minimizing erosion of the shoreline. Additionally, these trees will absorb nutrients from the water and will perpetuate the wooded wetland habitat along the DeBary Bayou shoreline. Arbors' own expert, Carla Palmer, also suggested the sprigging of eel grass in the dredged portion of DeBary Bayou. Such planting should be included as part of the mitigation plan. DER considered the cumulative impact of this docking facility. Four marinas are presently permitted on Lake Monroe and in the St. Johns River between Lake Monroe and Deland. DER considered these facilities' existence when it reviewed Arbors' application, and was satisfied that Arbors' boat dock facility would not have an adverse cumulative impact. There are no specific guidelines for a cumulative impact evaluation; accordingly, DER must apply its cumulative impact evaluation on a case-by-case basis. In the present case, there is no showing of adverse cumulative impacts from this project. Arbors' project will not adversely affect significant historical or archaeological resources recognized pursuant to applicable Florida or Federal Law. WVC was organized in March 1985, to oppose development in West Volusia County. WVC did not meet regularly and did not keep regular minutes of its meetings in the interim between organizing and filing the Petition in June 1986, for an administrative hearing on the Intent to Issue a permit for Arbors' project. When the Petition was filed, WVC did not have a membership roll, and was unsure how many members it had. Further, it is unclear as to how many members may have attended an "emergency" meeting to authorize filing said Petition. Approximately five months after said Petition was filed, WVC was incorporated and approximately nine months after the Petition was filed, WVC compiled a list of the people who were WVC members in June 1986. The emergency meeting WVC held in June 1986, to authorize filing said Petition was the first and the only such "emergency" meeting WVC ever held. The minutes of the emergency meeting have been lost. In June 1986, WVC may have had written rules authorizing emergency meetings and authorizing it to file suit, but its Chairman is unsure of this. Six of WVC's approximately 20 members may have lived within one mile of Arbors' project site in June 1986. Two of these members lived on waterfront property on Lake Monroe east of the 1-4 bridge. Some of these WVC members have never taken a boat west of 1-4 onto DeBary Bayou. WVC, as an organization, never sponsored outings or boat trips onto DeBary Bayou before filing the Petition. WVC's officers at the time of filing the Petition did not use DeBary Bayou for boating, fishing or swimming. No WVC members have ever seen manatees in DeBary Bayou. As with any other similar project on Lake Monroe, the boats which might be berthed at Arbors' project might add additional trash to the waters of Lake Monroe, might disturb the wildlife which WVC members might see on their property, and might cause wakes which might erode waterfront property. One of WVC's founders, who was an officer in June 1986, when WVC filed the Petition, stated that she would not be adversely affected in kind or degree any more than any other taxpayer in Florida. Friends timely intervened and its intervention was authorized by its membership at a regularly noticed meeting.

Findings Of Fact The City owns and operates a marina at the Godman Yacht Basin which is contiguous to Flamingo Canal a Class III body of water comprising a man made dead-end canal. Petitioners live along the Flamingo Canal. In 1924 DER issued a dredge and fill permit to the City of Cape Coral to allow the construction of 39 boat slips in the basin. That permit prohibited any boat and motor maintenance in the basin. In assessing the City's request for modification of this prohibition DER representatives visited the yacht basin and reinspected the facility and the land area from which water drains into the basin. Current regulations by the city prohibit the discharge of refuse or waste from boats in the basin. Nevertheless, as testified to by Petitioners' witnesses, refuse and waste is often discharged from boats and finds its way into Flamingo Canal. Petitioners' primary concern is that if boat maintenance is allowed, more boats will visit the basin and more fouling of the waters will occur. The survey by DER personnel found that the City had no equipment at the basin to contain or clean up an oil spill if one accidentally occurred, and that storm water run-off from one parking lot near the basin discharged more pollutants in the basin than could be expected from limited boat and engine maintenance. To alleviate the storm water run-off problem the City, as a condition to the removal of the boat repair prohibition, agreed to install infiltration trenches through which this run-off from the parking lot will pass before entering the basin. The City further agreed to provide oil/fuel spill control devices at the facility and to monitor the water quality in the basin and report its findings to DER. The infiltration trenches are designed to treat the first one-half inch of rainfall falling on this parking lot before it reaches the basin. The heaviest load of pollutants from paved surfaces used by automobiles is carried by the first surge of rainwater; therefore, a system designed to treat the first one-half inch of run-off is acceptable. The direct, untreated discharge of storm water into the yacht basin contributes more pollutants including oils, greases and heavy metals, to the basin than would the performance of minor boat and motor maintenance. Accordingly, the net result of allowing minor boat and motor maintenance coupled with the installation of the infiltration trenches will result in higher water quality in the basin. Petitioners contention that these infiltration trenches will treat only a small portion of the total storm water run-off entering the basin, while true, over- looks the maxim that half a loaf is better than no bread at all. No evidence was submitted that petitioners, as well as the majority of the population of the City of Cape Coral, are willing to pay the taxes required to raise the funds necessary to provide such treatment of all storm water run-off entering the basin. The permit proposed to be issued contains provisions which have been accepted by the City of Cape Coral. These include a requirement that the city provide oil/fuel spill control devices at the yacht basin; that all boat owners be provided with written information concerning protection of the basin's water quality; that only chlorine and biodegradable cleaning agents be used at the facility; and finally, the City submit to DER extensive water quality data for the basin through at least 1989, to permit a closer monitoring of the water quality in the basin by DER to insure acceptable water quality standards maintained.
