The Issue The issue is whether ADR of Pensacola should be issued a wetland resource permit and sovereign submerged lands authorization allowing the construction of a 30-slip docking facility on Big Lagoon, Escambia County, Florida.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background In this environmental permitting dispute, Petitioner, Michael L. Guttmann, who lives less than one mile from the project site, has challenged the proposed issuance by Respondent, Department of Environmental Protection (Department), of a Wetland Resource Permit (permit) and Sovereign Submerged Lands Authorization (authorization) which would allow Respondent, ADR of Pensacola (applicant), to construct a 30-slip docking facility on Big Lagoon, Escambia County, Florida. The facility will be part of a condominium project to be constructed on the upland portion of the property. As grounds for contesting the permit, Petitioner contended that the Department failed to consider "the long term health of Big Lagoon," navigational hazards created by the project, or public safety; failed to impose an adequate "monitoring program"; did not provide for a "contingency plan for hurricane activity"; failed to consider that the activity will degrade a nearby Outstanding Florida Water [OFW]; and failed to take into account "existing unused marina slips close by." The petition further alleged that the foregoing concerns constituted violations of Section 373.414, Florida Statutes (2000), and Rules 62-4.242, 62-302.300, 62-302.700, and 62- 312.080, Florida Administrative Code. The cited statute identifies "additional criteria" for issuing a permit while the first three rules pertain to OFWs. The last rule contains general standards for the issuance or denial of a permit. Petitioner raised no issues concerning the issuance of the authorization in his initial pleading. Until April 2000, the upland property was owned by the applicant. It was then sold to Harbour Pointe of Pensacola, Inc., which has subsequently entered into an agreement with the applicant allowing the applicant to construct the dock, operate the permit, and purchase a condominium unit. If the application is approved, applicant intends to construct a 442 feet x 4 feet access pier with seventeen 30 feet x 1.5 feet finger piers, thirteen 40 feet x 1.5 feet finger piers, and a 74 feet x 1.5 feet terminal platform, to form a 30-slip docking facility at 10901 Gulf Beach Highway on Big Lagoon, a Class III water in Escambia County, Florida. Approval to use the submerged lands is found in the authorization. The dock will be located in a "fairly pristine area" in Big Lagoon a few miles southwest of Pensacola, Florida. That body of water is six miles in length and is separated from the Gulf of Mexico by a slender coastal barrier island known as Perdido Key, which lies approximately one statute mile south of the project. Continuing west along the shoreline next to the project site are a string of single-family homes with small dock facilities, most of which are less than 1,000 square feet in size and thus exempt from Department permitting requirements. To the east of the undeveloped property are more undeveloped lots and a private yacht club with extensive docking facilities. The facility being challenged here will not be a public marina; rather, it will serve the residents of a proposed upland condominium (consisting of two buildings) to be constructed at the same location. The project is more commonly referred to as the Harbour Pointe Marina. It is fair to infer that Petitioner and adjoining property owners object not only to the dock, but also to the condominium project. The application and project When the application was originally filed with the Department in July 1995, it contained plans for a longer dock and more slips. Due to a reduction in the length of the pier and number of slips to conform to Department rules, other technical changes, and various requests by the Department for additional information, the draft permit was not issued by the Department until May 2000. The Department considers this a "major project" with "major [hydrographic and water quality] issues connected with it." In reviewing the application, the Department considered whether reasonable assurance had been given by the applicant that water quality standards would not be violated, and whether the additional criteria in Section 373.414(1)(a)1.-7., Florida Statutes (2000), had been satisfied. The Department concluded that water quality standards would not be degraded, and that the project, as designed and permitted, was not contrary to the public interest. In making the public interest determination, the Department typically assigns a plus, minus, or neutral score to each of the seven statutory factors. In this case, a neutral score was given to historical and archaeological resources [paragraph 373.414(1)(a)6.] since there were none, while the permanent nature of the project [paragraph 373.414(1)(a)5.] caused it to be rated "a little bit on the minus side"; all other factors were given a plus. Department witness Athnos then concluded that on balance the project "was a plus because it will not adversely affect any of these things." The access pier (dock) runs perpendicular from the shoreline and stretches out some 442 feet to where the water reaches a depth of seventeen feet, which is the deepest point in Big Lagoon. The unusual length of the dock is required so that the boat slips will begin past the seagrass colony (which lies closer to the shore), to prevent boat propeller blades from cutting the top of the seagrass, and to reduce the amount of sedimentation stirred up by the boat propellers. Aerial photographs confirm that when completed, the dock will probably be the largest in Big Lagoon, and much larger than the neighboring docks to the west. The use of boat slips will be limited to condominium owners. Only 19 slips will be constructed initially, since the applicant has secured approval at this time for only the first phase of the condominium project. When approval for the second phase is secured, the applicant intends to add an additional 11 slips. Water quality In his initial pleading, Petitioner made a general allegation that the Department failed to consider "the long term health of Big Lagoon"; there were no specific allegations regarding water quality standards. In his Proposed Recommended Order, however, he argues that the [a]pplicant failed to provide reasonable assurances that water quality standards would not be violated." Assuming arguendo that the issue has been properly raised, Petitioner has still failed to substantiate his allegation. That portion of Big Lagoon where the project will be located is a Class III water of the State. Studies on metals, greases, oils, and the like submitted by the applicant reflected that the "water quality [in that area] did not exceed the standards in Rule 62-302." To provide further reasonable assurance regarding water quality standards, the applicant has voluntarily agreed to use concrete piling and aluminum docks. Unlike wooden piling and docks, these types of materials do not leach toxic substances such as arsenic, copper, and acromiom into the water. In addition, special permit conditions require that sewage pumpout equipment be located at the site so that boats will not discharge raw sewage into the waters. Liveaboards are prohibited, and fueling will not be available at the facility. Finally, the cleaning of fish is not allowed, and boat owners cannot scrape their boat bottoms while docked at the facility. All of these conditions are designed to ensure that water quality standards will not be violated. Enforcement mechanisms for the above conditions are found in either the permit itself or Chapter 403, Florida Statutes. Also, one of the conditions in the draft permit expressly states that the applicant is not relieved of liability for harm or injury to humans, plants, or property caused by the construction of the dock. However, if a permit is issued, Condition 9 of the permit should be modified to require that trained personnel be available twenty-four hours per day, rather than just during standard business hours, to assist boaters with, and ensure that they use, the sewage pumpout equipment. Any permit issued should also require that boats be placed on lifts while using the docking facilities. This will prevent any leaching of paint from the boat bottoms into the waters. Otherwise, the paint would cause a degradation of the water. The more persuasive evidence supports a finding that, with the additional conditions, reasonable assurance has been given that the state water quality standards applicable to Class III waters will not be violated. Outstanding Florida Waters In his complaint, Petitioner has contended that "the proposed activity will degrade an [OFW] as a result of its close proximity to the Gulf Islands National Seashore," and that the"[D]epartment has made no analysis of this project['s] impact on the [OFW] which is adjacent to the proposed activity." The record discloses that the southern portion of Big Lagoon has been designated as an OFW. This area includes the waters around Gulf Islands National Seashore and Big Lagoon State Park; they begin approximately 650 to 700 feet south of the end of the dock. As noted earlier, the project is located within Class III waters. Because the Department found that no violation of state water quality standards in those waters would occur, it likewise concluded, properly in this case, that the project would have no impact on any OFW, even though such waters begin some 650 or 700 feet away. Under these circumstances, there would be no reason to assess the water quality in the OFWs or the projected impacts on those waters, as Petitioner suggests. In the absence of any credible evidence to the contrary, it is found that the project will not adversely impact an OFW. Hydrographic characteristics If a dock has more than ten boat slips, the Department routinely conducts a hydrographic (flushing) study to determine whether the structure will adversely affect the flow of the water in the area or cause erosion or shoaling on adjacent properties. In the summer of 1999, a Department engineer conducted a hydrographic study using a dye tracer and concluded that flushing characteristics were excellent and that there would be no adverse effects caused by the project. This conclusion has not been credibly contradicted. Therefore, it is found that the dock will not adversely affect the flow of water or cause harmful erosion or shoaling. Navigational issues In his initial pleading, Petitioner raised a contention that the project will create "navigational hazards" because the dock "extends nearly into a navigation channel which routinely carries commercial towboats transporting hazardous material, the spill of which would adversely affect Big Lagoon." He also alleges that the rupture of a vessel could impact public safety. Channel markers placed by the U.S. Army Corps of Engineers in the Intracoastal Waterway (of which Big Lagoon is a part) define a navigational channel for boats approximately 400- 500 feet south of the end of the proposed dock. That channel is used by both recreational and commercial traffic, including barges and other large watercraft which regularly haul oil, chemicals, and other products through the Intracoastal Waterway to and from Pensacola, Panama City, and St. Marks, Florida. The water in the marked channel is only thirteen feet deep. Because the U.S. Army Corps of Engineers has jurisdiction over the maintenance of the marked channel, the Department defers to that entity's judgment in determining whether a proposed structure will impede navigation in the marked channel. The proposed dock ends near the deepest part of the natural channel where the water reaches a depth of seventeen feet. Because of the deeper water to the north, which allows the boat captain to "get better steerage," the commercial boat traffic sometimes tends to follow the natural channel, rather than the marked channel formed by the navigational aids. When they do so, however, they are straying from the so-called "legal" channel. Petitioner's expert, a retired tugboat captain, opined that in a storm or squall, a commercial boat using the natural rather than the marked navigational channel might be blown extremely close to the dock or even strike it, thus causing a hazardous situation. He acknowledged, however, that he was not predicting more accidents because of the construction of the dock; he also admitted that the dock would not cause ships to "sudden[ly] have problems navigating that Big Lagoon." The location of the proposed dock was shown to the U.S. Army Corps of Engineers and the Florida Marine Patrol, and there were no adverse comments regarding this issue by either agency. In the absence of any negative comments by those agencies, and the acknowledgement by Petitioner's own witness that the dock will not cause accidents or create navigational problems for other boaters, the more persuasive evidence supports a finding that the project will not adversely affect navigation or public safety in Big Lagoon. Seagrass and monitoring Petitioner has alleged that Big Lagoon "is the healthiest body of water in Escambia County with a white sand bottom and abundant seagrass," and that the proposed project will adversely affect its "long term health." He also alleges that the Department has failed to provide a "remedy or punishment should the results [of the Department's monitoring plan] indicate that the seagrass has been harmed"; that the Department's monitoring plan is not "of sufficient duration to reasonably report the long-term effect of concentrated mooring and traffic" or "sufficiently specific to insure usable data"; and that the data relied upon by the Department [such as photographs] were not "sufficient" to determine the existing health of the seagrass. The evidence reflects that a "nice, healthy seagrass community" is found in the area where the dock will be constructed. It stretches out several hundred feet from the shoreline to where the water reaches a depth of around six feet. The Department considers seagrass to be a "most important resource" which should be protected. This is because seagrass is essential for "binding" the shoreline and stabilizing the sediments, and it serves as a nursery area for juvenile fish and shellfish. Indeed, due to these beneficial effects, far more species of shellfish are found in areas where seagrass thrives than in areas where no seagrass exists. To protect the seagrass, the dock has been extended out 442 feet from the shoreline so that the first boat slip begins at a depth of seven feet, or just past where the seagrass ends. This will prevent the scarring of the grass by boat propellers and reduce turbidity that is typically caused by propeller dredging and boat wakes. Thus, at least theoretically, no boat activity by condominium owners is contemplated in waters of less than seven feet. Because seagrass requires as much light as possible to survive, educational signs will be posted in the area to warn boaters that seagrass is found closer to the shoreline, and that mooring in that area is prohibited. There is, however, no enforcement mechanism to ensure that condominium owners or nonresidents comply with these warnings. Under the draft permit, the Department is allowed to access the premises at reasonable times for sampling or monitoring purposes. A special section of the draft permit includes a number of requirements pertaining to the monitoring of turbidity levels during dock construction while another section requires the applicant to take photographs of the existing seagrass beds at numerous locations before, during, and after construction of the dock. Condition 14 requires that the permittee maintain "records of monitoring information" for at least three years. The evidence supports a finding that if a permit is issued, a mapping of the seagrass should be made prior to construction of the dock and during the height of the growing season (September and October). When the photographing of the area is performed, the applicant should use a sampling protocol that is based on a scientifically determined method. Also, both affected and unaffected areas should be monitored to compare the effect of the additional boat traffic on the seagrass after the dock is constructed. All of these conditions should be incorporated into any issued permit. According to Dr. Heck, a marine biologist who specializes in the study of seagrass and testified as an expert on behalf of Petitioner, seagrass beds in Big Lagoon have been "shallowing up" or thinning out in recent years due to decreasing water clarity. In other words, as the water becomes cloudier from more and more boat activity, the sunlight cannot penetrate and the seagrass will not thrive. The seagrasses most susceptible to disappearing are those that are found at the deepest depth. Doctor Heck attributed the decline in seagrass to increased human activity in the area. This activity is related not only to the existing homeowners in the area, but also to the non-resident boaters (both recreational and commercial) who use the waters in that area. A Department study conducted in 1995 confirmed that the only seagrass area in North Florida "significantly affected" by propeller scarring was an area in Big Lagoon known as Scallop Cove, near Spanish Point. This study is consistent with those studies performed by Dr. Heck in the late 1990's, and one as recently as last year, that support a finding that seagrass in Big Lagoon is on the decline due to both propeller scarring and increased turbidity caused by wakes from larger recreational boats. For this reason, Dr. Heck concluded that the addition of thirty boats at the project site, some of which would be as large as 30 feet or so, would have a "negative effect" on the seagrass colony. This in turn will cause a negative effect on the marine productivity in the area, as well as the conservation of fish and their habitat. Doctor Heck's testimony on this issue is found to be the most persuasive. Other concerns Petitioner further contends that the Department failed to provide a "meaningful contingency plan for hurricane activity." This matter, however, is beyond the permitting jurisdiction of the Department. Petitioner has also contended that the Department failed to take into account "existing unused marina slips close by" which could be used by the condominium owners. Like the prior issue, this matter is not a consideration in the permitting scheme. Another issue raised by Petitioner, albeit untimely, was that the construction of this dock could lead to further development in Big Lagoon. There was, however, no evidentiary support for this contention. Indeed, there is no evidence that future permit applications with impacts similar to this application can reasonably be expected in the area. At hearing, Petitioner raised for the first time a contention that the applicant no longer owns the upland property and thus a permit/authorization cannot be issued to that entity. Aside from this issue being untimely, the fact that a permit holder does not own the upland property is not unusual. If this occurs, permits and authorizations (leases) are routinely transferred to the new owner once the Department receives the necessary title information. It is not a ground to defeat the application. Petitioner also raised for the first time at hearing a contention that the site plan approval for the condominium has expired under a provision of the Escambia County Land Development Code and therefore the permit should be denied. Again, the issue is untimely; more importantly, it should be addressed in another forum since the Department has no jurisdiction over this issue. Likewise, a legitimate concern by an adjoining property owner, witness Hobgood, and an area realtor, that Hobgood's single-family property would probably decline in value if the project is built is nonetheless beyond the Department's jurisdiction. Finally, a contention that the Department improperly calculated the maximum number of boat slips for an 88-unit condominium project has been rejected. The record contains a lengthy explanation by witness Athnos which shows that the Department's calculation under Rule 18-21.004(4)1., Florida Administrative Code, was correct. Those calculations are also detailed in Respondents' Exhibit 14.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Department of Environmental Protection enter a final order denying the application of ADR of Pensacola for a wetland resource permit and sovereign submerged lands authorization.

Findings Of Fact The County applied on August 24, 1979, for a permit to construct a swimming beach on the southwest shore of Sylvan Lake in the northwest part of Seminole County, Florida. On December 4, 1979, the Department gave notice of its intent to grant the permit. As proposed, the beach would be 150 feet in length along the shoreline and be approximately 65 feet deep, 40 feet on the land side of the waterline and 25 feet on the lake side of the shore waterline. Three dock structures are also proposed. The first is a boat dock to be 6 feet wide, which will extend into the lake for 25 feet with a 15 foot "L" at its end. In addition, a 6 foot wide, 20 foot long fishing pier is proposed with a 6 by 20 foot "T" on its end. Finally, the County proposes constructing a 6 foot wide 15 foot long aquatic study platform that would terminate in a 6 by 30 foot "T". The County plans to remove vegetation from an area of 150 feet long by 25 feet. As agreed at the hearing, this removal would be by hand only.. No machinery would be used. The site of the project is owned by the County. As part of its application, the County agrees to leave undisturbed 2,630 feet of the remaining shoreline it owns. At the present time approximately 20 percent of the lake's total shoreline is occupied by developed residential property. Many of the homeowners have removed the vegetation from their shorelines. The County's agreement not to alter 90 percent of its shoreline would therefore be beneficial to preserving the natural state of the lake. Sylvan Lake is an oligotropic spring-fed lake of 160 acres. Its well vegetated shoreline alternates between large grassy marshes and well-defined uplands. The lake bottom in the project site is firm sand with little potential for causing a turbidity problem. The lake has excellent water quality. It is a valuable habitat for fish and aquatic dependent birds and mammals. The vegetation along the shoreline of the project site consist of sawgrass, pickerelweed, and some arrowhead on the land side with spatterdock and mats of floating maidencane on the water side. In a freshwater closed system such as this lake the rooted emergent plants are vital to maintaining the quality of the water. The plants stabilize nutrients, expert oxygen and keep the water cool. The removal of this vegetation from a 150 foot strip will have an adverse but insignificant impact on the biological resources and the water quality of the lake. The construction of the fishing pier, boat dock, and observation platform will have no lasting environmental impact and the limited turbidity which may be generated during their construction can be well contained by the use of turbidity curtains. The swimming beach is a part of the County's plan for a diverse recreational park to provide the public with facilities for nature trails, baseball, picnicking, etc. The water classification of Sylvan Lake is Class III. CONCLUSIONS OF LAW The Division of Administrative Hearings has jurisdiction over the parties and the subject matter of this case. Section 120.57(1), Florida Statutes (1979). In this proceeding the Respondent, County, has the burden of proving that it has given reasonable assurances that the short term and long term effects of the proposed project will not result in violations of the water quality standards of Chapter 17-3, Florida Administrative Code. Section 17- 4.28(3), Florida Administrative Code; Dowdy v. Department of Environmental Regulation, Case No. 79-219, Recommended Order (DOAH July 19, 1979). That burden has been carried. The water quality standards of a Class III body such as Sylvan Lake are set out in Section 17-3.09, Florida Administrative Code. There is a preponderance of competent and substantial evidence that those standards in either the long term or in the short term will not be violated by the proposed project. The requisite reasonable assurances have therefore been given by the applicant. Hand removal of aquatic vegetation from a 150 foot strip of shoreline on a 186 acre lake, will have at most, a de minimus impact on the marine life, water quality or neighboring biota of Sylvan Lake. The applicant has met the criteria for the issuance of a permit, pursuant to Section 17-4.07, Florida Administrative Code.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That a final order be entered by the State of Florida, Department of Environmental Regulation determining that the requested dredge and fill permit be issued subject to the usual conditions and subject to the applicant's stipulation that any vegetation removal will be performed by hand and subject to any conditions contained in the Notice of Intent To Issue Permit.

The Issue The issues to be determined in this case are whether Petitioner is entitled to an environmental resource permit and modified sovereignty submerged land lease for the construction of commercial marinas and related structures at Petitioners property in Lee County, Florida. PRELIMARY STATEMENT On October 23, 2006, Petitioner applied to the South Florida Water Management District (“District”) for an environmental resource permit (“ERP”). Petitioner also sought modification of its sovereignty submerged land lease ("Lease") from the Board of Trustees of the Internal Improvement Trust Fund (Board of Trustees). On September 28, 2007, the District issued a Staff Report recommending that the ERP and Lease be denied. The Governing Board of the District adopted the staff’s recommendation on October 11, 2007. On October 12, 2007, the Petitioner filed a Petition for Administrative Hearing challenging the agency action. The District referred the petition to DOAH to conduct an evidentiary hearing. The case was abated for an extended period of time during which the parties attempted to settle their disputes. In October 2009, Intervenors' petition to intervene was granted. Intervenors were subsequently granted leave to amend their petition. Following notice from the parties that they were unable to settle their disputes, a final hearing was scheduled. At the final hearing, Petitioner presented the testimony of: Michael Morris, Jr.; David Depew; and Hans Wilson, accepted as an expert in ocean engineering, environmental sciences and navigation. Petitioner presented the testimony of Anita Bain through the introduction of her deposition. Petitioner's Exhibits 5, 8, 9, 14 through 16, 19, 20, 24, 26, 30, 34, 35, 40 through 43, 46 through 50, 52, and 56 through 58, were admitted into evidence. Petitioner's Exhibit 35 was accepted as a proffer. The District presented the testimony of: Holly Bauer- Windhorst, accepted as an expert in environmental biology; Melinda Parrott, accepted as an expert in marine biology and environmental impact analysis; Anita Bain, accepted as an expert in biology and environmental impact assessments; Robert Brantly, a professional engineer and Director of the Department's Bureau of Coastal Engineering; and Mary Duncan, accepted as an expert in biology and manatee impact assessment. The testimony of Peter Eckenrode was presented through his deposition. The District's Exhibits 5, 10, 12, and 14 through 18 were admitted into evidence. Intervenors presented the testimony of: Leonardo Nero, accepted as an expert in marine biology, seagrass conservation, oceanography, navigation, and vessel operation and maintenance; Gary Shelton; Sally Eastman; and Christine Desjarlais-Leuth. Intervenors' Exhibits 1, 5, 7, 8, 9, and 14 were admitted into evidence. The two-volume Transcript of the hearing was filed with DOAH. The parties filed proposed recommended orders. Petitioner filed revised pages to its proposed recommended order to correct scrivener's errors. Petitioner moved to strike an issue that was raised for the first time in the District and Intervenors' Joint Proposed Recommended Order. The motion to strike is granted as discussed in the Conclusions of Law.
Findings Of Fact The Parties Petitioner, Highpoint Tower Technology, Inc., is a Florida corporation with its mailing address at 800 South Osprey Avenue, Building B, Sarasota, Florida 34246. Petitioner is the owner of property located in Section 25, Township 45 South, Range 22 East, in Lee County, Florida, consisting of approximately eight acres. The property is on Bokeelia Island, on the northern tip of Pine Island. Petitioner is the applicant for the ERP and Lease which is the subject of this proceeding. The District is a regional water management agency with powers and duties established in Chapter 373, Florida Statutes. Its principal office is located at 3301 Gun Club Road in West Palm Beach. The District regulates certain construction activities in waters of the state pursuant to Chapter 373, Part IV, Florida Statutes, and Florida Administrative Code Chapter 40E. The District has also been delegated authority from the Board of Trustees to process applications for submerged land leases for structures and activities on or over sovereignty submerged lands. See Fla. Admin. Code R. 18-21.0051. Intervenor Sally Eastman resides on property adjacent to the proposed project. Intervenors, Christine Desjarlias-Leuth and Ron Leuth, own and reside on riparian property approximately 400 feet from the proposed project. Intervenor Gary Shelton owns and resides on riparian property near the proposed project. All Intervenors use the waters of Charlotte Harbor for water-based recreational activities, including fishing, swimming, boating, wading, and nature observation. The Affected Waterbodies The north side of Petitioner's property is adjacent to Charlotte Harbor. The south side of the property is adjacent to Back Bay. Both waterbodies are within the Pine Island Sound Aquatic Preserve. The aquatic preserve is an Outstanding Florida Water. Aquatic preserves are so designated because they have exceptional biological, aesthetic, and scientific value. It is the intent of the Legislature that aquatic preserves be set aside forever as sanctuaries for the benefit of the public. See § 258.36, Fla. Stat. Aquatic preserves were established for the purpose of being preserved in an essentially natural or existing condition so that their aesthetic, biological and scientific values may endure for the enjoyment of future generations. See Fla. Admin. Code R. 18-20.001(1). Charlotte Harbor in this location is a large expanse of open water with 10 to 12 miles of fetch to the north, making it subject to high winds and waves during storms. The water bottom of Charlotte Harbor is sandy. There are many areas of Charlotte Harbor with "prop scars," which are caused when boats travel in shallow waters and impact the bottom with boat motor propellers. There are seagrasses growing in the vicinity of Petitioner's Charlotte Harbor shoreline, mostly Thallasia testudinum (turtle grass) and Syringodium filiforme (manatee grass). Healthy turtle grass beds are growing near the proposed marina structures in Charlotte Harbor. There was some dispute about whether the turtle grass is 12 inches or 18 inches in length. The more persuasive evidence is that mature turtle grass is 18 inches in length. If there is turtle grass of shorter length in the area of the proposed project, it will eventually mature to a length of 18 inches. These seagrass communities qualify as a Resource Protection Area ("RPA") 1, which is defined in Florida Administrative Code Rule 18-20.003(54) as "[a]reas in aquatic preserves which have resources of the highest quality and condition for that area." There is also small patch of soft whip coral offshore, as well as some sea lettuce and interstitial algae on the sandy bottom. No water quality data for this area of Charlotte Harbor was presented by Petitioner. West Indian manatees are known to forage and move in the area near Petitioner's Charlotte Harbor shoreline, as well as in Back Bay. The manatee is a "listed" species. Back Bay is a small, semi-enclosed bay. It is shallow, averaging around four feet in depth at mean low water. A narrow passage known as Jug Creek leads out of Back Bay to Pine Island Sound. There are no seagrasses along Petitioner's shoreline on Back Bay, but there are seagrasses elsewhere in Back Bay. There are many prop scars in the shallower areas of Back Bay. The water bottom in Back Bay is silty and organic. It can be easily stirred up by boats and propeller action. No water quality data for Back was presented by Petitioner. Existing Structures A public access fishing pier extends about 400 feet from Petitioner's property into Charlotte Harbor, generally forming a "T." The pier has existed for decades and was one of the first landing and offloading piers in the region for commercial fishing activities, with fish houses on the adjacent uplands. The riparian owner obtained title to the submerged lands beneath the fishing pier by operation of the Butler Act, which vests title in the riparian upland owner to submerged lands if structures were erected over or upon the submerged lands before 1951. Therefore, a submerged land lease from the Board of Trustees is not required for the fishing pier. However, Petitioner obtained a submerged lands lease in 2000 for two recreational boat slips along the east side of the pier. There is a seawall along Petitioner's Charlotte Harbor shoreline. Petitioner's upland was formerly occupied by approximately 120 mobile homes, which were served by septic tanks. The mobile homes were removed two or three years ago and Petitioner obtained a separate environmental resource permit from the District in May 2006 for a proposed new residential and commercial development on the uplands called Bokeelia Harbor Resort. Construction of the new development, which would include single-family homes, multi-family buildings, a swimming facility, and a restaurant, has not yet begun. In Back Bay, Petitioner's shoreline has a seawall and a number of finger piers extending off the seawall. Petitioner has two submerged land leases in Back Bay, one that authorizes 50 boat slips and another that authorizes 10 slips. Only about a dozen boats have been using these slips in recent years. There are two boat ramps on Petitioner's property for access to Back Bay. The record evidence leaves unclear whether the ramps were for the exclusive use of the former mobile home residents or were used by the general public. The historical and current use of the boat ramps, in terms of the average number of launches per month or year, was not established in the record. There is a man-made, seawalled canal or basin on Petitioner's property that connects to Back Bay. There are piers and slips in the canal, which Petitioner claims could accommodate about 30 boats. Aerial photographs of the canal indicate that 20 to 25 boats is a more reasonable estimate. The water bottom of the canal is privately owned and, therefore, does not require a submerged lands lease. Petitioner presented inconsistent information about the number of existing boat slips in Back Bay. Petitioner claimed that there are as many as 108 slips in Back Bay. That number seems impossible, given that only 60 slips are authorized by the two submerged land leases. There was no exhibit presented to show where the 108 slips are located. The Department of Community Affairs determined that 85 slips in Back Bay were "vested" for purposes of the development of regional impact review program in Chapter 380, Florida Statutes, which means the slips were constructed before July 1, 1973. The Florida Fish and Wildlife Conservation Commission thinks there are now 82 boat slips in Back Bay. The Department of Environmental Protection thinks there are 80. Petitioner had a motive to exaggerate the number of existing slips. The unsupported testimony of Petitioner's witness that there are 108 slips in Back Bay was not substantial evidence.1/ It is found that Petitioner currently has approximately 82 boat slips in Back Bay. Petitioner is not currently controlling the use of the slips in Charlotte Harbor and Back Bay, such as by limiting the size or draft of vessels. There are no signs that inform boaters about seagrasses or manatees. There are currently no sewage pump-out facilities. Petitioner is not currently controlling boaters' uses of fuel or other chemicals. However, no evidence was presented to show the extent of any past or current polluting activities. Petitioner sought to show that the septic tanks that had been removed from the upland property were a source of nutrients and other pollutants to Charlotte Harbor. The District and Intervenors objected to this evidence as irrelevant because the ERP and Lease applications do not involve the removal of the septic tanks and their replacement with a central sewage collection system, and because Petitioner removed the septic tanks some years ago as part of its re-development of the uplands. The objection was sustained, but Petitioner was allowed to make a proffer that the removal of the septic tanks improved the water quality of the adjacent waterbodies. The issue was one of relevancy alone, because it was apparently undisputed that the removal of the septic tanks resulted in some unquantified improvement in the water quality of adjacent waterbodies.2/ The Proposed Project Petitioner proposes to construct new commercial docks and related structures (marinas) in both Charlotte Harbor and Back Bay. The Charlotte Harbor marina would have 24 boat slips, which is 22 more slips than currently exist. The Back Bay marina would have 43 slips, which is 39 fewer slips than currently exist. Overall, the proposed project would result in a reduction of about 17 slips. Petitioner would make all boat slips in the marinas available to the public on a “first come - first served” basis. Some slips would be leased on an annual basis. An unspecified number of slips would be for day rental, primarily to accommodate patrons of the restaurant on the uplands. In Charlotte Harbor, a long pier would extend to a dock configuration that forms a marina basin, with concrete panels on three sides extending from above the water line to below the sandy bottom to act as a breakwater. The opening into the marina basin for ingress and egress by boaters would be to the southeast. On the west side of the marina basin would be a 1500 square foot fishing platform. Slips 1 through 5 would be along the east side of the pier and would have boat hoists to raise the boats out of the water. Because seagrasses are growing near slips 1 through 5, Petitioner agreed to limit the draft of boats using these slips to 30 inches. Slips 6 through 24 would be within the protected marina basin. These slips are intended to accommodate larger boats than the kinds of boats that can safely navigate in the shallow waters of Back Bay. However, boats using slips 6 through 24 would not be allowed to have drafts greater than five feet. These slips would not have hoists. All the new slips in Back Bay are designed for a maximum boat length of 30 feet, but the slips vary with regard to maximum allowed draft, from 16 inches to three feet, depending on the depth of the adjacent waters. The Charlotte Harbor marina would extend about 100 feet more waterward so that it would be 500 feet from the shoreline, which is the maximum extension allowed under Florida Administrative Code Rule 18-20.004(5)(a)1. No boats slips or mooring would be allowed beyond the 500-foot limit. The canal connected to Back Bay would be filled in, and three additional residential units would be placed on the uplands created by the filling. Petitioner suggested that the canal has poor water quality, such as low dissolved oxygen, and that elimination of the canal would be a benefit for the water quality of Back Bay. Petitioner presented no water quality data to support this allegation, but the elimination of the canal would more likely than not have some small water quality benefit for Back Bay. The boat ramps on the upland would be removed. A new seawall would be installed along Petitioner's Back Bay shoreline and approximately 400 reef balls would be placed in the water along the face of the seawall. The reef balls are three feet tall and four feet wide, made of cement, and have openings. It is expected that oysters and barnacles would colonize the reef balls. Because there are oysters, barnacles, and other filter feeders in Back Bay, that expectation is a reasonable one. Fish are likely to be attracted to the reef balls. Petitioner contends that the reef balls, after they are colonized by oysters, will provide water quality benefits, because oysters filter the water when feeding. Although there was some support in the record for this general proposition, there was no evidence presented about the types of pollutants that can be removed from the water by oysters, or the level of water quality improvement that reasonably could be expected. Reef balls have been used at another marina in the region and were determined by the regulatory agencies to provide some public benefit, but Intervenors' expert, Leonard Nero, believes that the value of reef balls is exaggerated. It is his opinion that reef balls do not function like a natural habitat because there is no primary food production or sustainable biological interrelationships. It is found that the proposed reef balls would provide some small environmental benefits to the Back Bay ecosystem. In Back Bay, there are currently no channel markers except in Jug Creek. Petitioner proposes to provide channel markers so that boats entering and leaving the marina would be guided away from shallower waters and away from seagrasses. Petitioner prepared a Marina Management Plan to govern the operation of the marinas, including the use of the slips. The management plan requires waste receptacles and restricts the use and storage of fuel and other chemicals. The plan also includes an education program to inform marina users about water quality and habitat protection. A harbor master would be employed to oversee the operation of the marinas. The harbor master would be responsible for assuring compliance with the requirements in the Marina Management Plan, including maximum boat drafts, fuel spill prevention and clean-up, proper use of sewage pump-out facilities, prevention of hull cleaning and use of deleterious boat cleaning products, and proper disposal of fish cleaning wastes. The harbor master's office would be located on the docks over Charlotte Harbor. The District and Intervenors are not impressed with Petitioner's proposal to employ a harbor master to control marina activities because the harbor master would not be at the marinas 24 hours a day and could not be present at both marinas at the same time. However, the employment of a harbor master would strengthen the use and enforcement of the Marina Management Plan. There would be educational signs for boaters with information about manatees and seagrasses. Petitioner proposes to install sewage pump-out facilities at both marinas that would be connected to the sewage collection system that will serve the upland development. The proposed project includes modifying the proposed upland residential development to add three residential units and a cul de sac, and enlarging a stormwater retention area to accommodate the associated stormwater impacts. Project Impacts Seagrasses It is usually difficult and sometimes impossible for seagrasses to re-colonize an area that has been prop-scarred. Seagrasses are the primary food of manatees, so an adverse impact to seagrasses is an adverse impact to manatees. The seagrasses to the east of the entrance of the proposed Charlotte Harbor marina are subject to disturbance from boats entering and leaving the marina. Boats approaching or departing from slips 1 through 5 are likely to cross these seagrasses from time to time. The water depth in the area of slips 1 and 2 is about minus five feet (mean low water) at the shallowest. For any seagrasses growing at minus five feet, and assuming the seagrasses are 18 inches in length, the clearance between the bottom of a boat with a 30-inch draft and the top of seagrasses would be 12 inches at mean low water. District and Intervenors are also concerned about the potential impacts to the seagrasses near the proposed Charlotte Harbor marina from large boats using slips 6 through 24, which could have a draft of five feet. About 260 feet to the east of Petitioner's pier is another pier, known as Captain Mac's Pier. There are seagrasses between the two piers. Boaters wanting to reach slips 6 through 24 would have to navigate past Petitioner's marina basin, into the area between Petitioner's pier and Cap'n Mac's pier, and then make nearly a 180 degree turn to enter the marina basin. The more persuasive record evidence indicates that this maneuver would sometimes be difficult for inexperienced or inattentive boaters even in relatively calm conditions. In windy and storm conditions, the maneuver would be difficult even for experienced boaters. If there are tethered buoys marking the limits of the seagrasses, as proposed by Petitioner, the buoys would add to the navigational challenge. The preponderance of the credible evidence shows that it is likely that boaters in vessels with drafts greater than 30 inches, when entering or leaving the marina basin, would sometimes cross the seagrasses and do damage to the seagrasses and other submerged resources. Another potential adverse impact to seagrasses is shading caused by structures. Shading caused by the existing fishing pier in Charlotte Harbor appears to have impeded the growth of seagrasses in some areas near the pier. The proposed breakwater for the Charlotte Harbor marina presents a relatively unique shading issue. Petitioner did not adequately demonstrate that shading from the proposed structures in Charlotte Harbor would not adversely affect seagrasses. The District and Intervenors contend that the proposed project would also cause adverse impacts to seagrasses in Back Bay. However, because Petitioner has reduced the numbers of slips in Back Bay and eliminated the boat ramps, the boat traffic in Back Bay should be reduced. Furthermore, Petitioner would restrict boat drafts and mark a channel to guide boaters to deeper waters and away from seagrasses. Therefore, the proposed project would likely reduce the risk of damage to seagrasses and other submerged resources in Back Bay. The District and Intervenors describe Petitioner's proposal to install channel markers in Back Bay as too "tentative" because there is another developer that has proposed to install channel markers and Petitioner's proposal is to install the markers if the other developer does not. However, the details of the channel marking are in evidence. If the channel marking is made a condition for construction of the proposed project, it can be considered a part of the reasonable assurance of compliance with relevant permitting criteria. No specific evidence regarding the general health and value of the seagrasses in Back Bay was presented. The seagrasses in Back Bay are not designated as an RPA. There was no evidence presented that there is soft coral or other submerged resources in Back Bay. Therefore, the reduced risk of harm to the seagrasses in Back Bay does not offset the potential harm that the proposed project would cause to the seagrasses and other submerged resources in Charlotte Harbor. Manatees Petitioner agreed to comply with all of the conditions recommended by the Florida Fish and Wildlife Conservation Commission related to the protection of manatees: In order [to] ensure a minimum clearance of 12 inches above the top of seagrass so as to avoid damage located in the project ingress/egress route, the maximum draft, including propeller(s), for vessels associated with slips 1-5 in Charlotte Harbor shall be 30 inches. The Standard Manatee Conditions for In- Water Work (revision 2009) shall be followed for all in-water activity. Handrails shall be constructed and maintained along the access pier and the landward side of the terminal platform to prevent mooring outside of the designated slip areas. The Permittee shall develop and implement a Florida Fish and Wildlife Conservation Commission (FWC)-approved marina educational program prior to slip occupancy. The Permittee shall develop this educational program with the assistance of FWC, and FWC shall approve this education plan prior to its implementation. The program may include (at a minimum) the posting of permanent manatee educational signs and the display of brochures in a prominent location. The educational program must be maintained for the life of the facility. The [Permittee] shall install and maintain seagrass marker buoys as depicted in the site plan for the docks in Charlotte Harbor. The buoys must be permitted by the U.S. Coast Guard and the Florida Fish and Wildlife Conservation Commission's Boating and Waterways Section, and maintained for the life of the project. The [P]ermittee shall provide bins for the disposal of or recycling of monofilament line or other used fishing gear. The [P]ermittee shall also provide educational signs encouraging the use of these bins. Larger boats are generally more lethal in collisions with manatees because there is usually more momentum involved. Greater momentum generally causes deeper propeller cuts and other serious physical injury. Slips 6 through 24 in the Charlotte Harbor marina would accommodate boats of greater size (up to five-foot draft) than would have used the slips that would be eliminated in Back Bay, creating some small, unquantified additional risk of increased injury or death to manatees in Charlotte Harbor and other area waters. Lee County reviewed the proposed project against the Lee County Manatee Protection Plan and scored the project as "Preferred." The factors that the County considered in scoring the project were not explained. The reduction of boat traffic in Back Bay that would result from the eliminating boat slips and removing the boat ramps, and the marking of a channel away from seagrasses in Back Bay, would reduce the current risk to manatees using Back Bay. However, that reduction of risk is offset by the increased risk of injury to manatees associated with the addition of 17 larger slips in the Charlotte Harbor marina, the potential for collisions with any manatees foraging in the seagrass near the Charlotte Harbor marina, and the potential loss of seagrasses from boat impacts and shading. The overall effect of the proposed project on manatees would probably be negative. Water Quality The District and Intervenors contend that the proposed project would cause additional pollution associated with boating activity and, therefore, would violate the water quality standard applicable in Outstanding Florida Waters that ambient water quality cannot be degraded. However, Petitioner would reduce the total number of boats that could operate out of the marinas and would implement a number of prohibitions and other management practices that would reduce the potential for pollution when compared to the current situation. There was no evidence presented to quantify the pollution that might now be occurring as a result of the absence of pump-out facilities at the marinas, or the presence of related pollution in Charlotte Harbor or Back Bay. However, it was undisputed that the availability of pump-out facilities is generally a benefit for water quality. Petitioner has not indicated where the sewage pump-out facilities would be located. Although this is a relatively minor issue, the location of these facilities can affect the potential for pollution and, therefore, it is reasonable for the District to require this information before the ERP can be approved. Although the District and Intervenors contend that insufficient information was presented regarding flushing characteristics in Charlotte Harbor, that contention is inconsistent with their claim that strong winds, waves, and tidal forces that occur in this area of Charlotte Harbor would cause shoaling and scour at the breakwater. There is sufficient evidence that the Charlotte Harbor marina would be well flushed. An issue was also raised about the potential for turbidity problems in Back Bay caused by disturbance of the silty bottom by boats using the Back Bay slips. However, the reduction of the number of boats that would operate out of the Back Bay marina, the marina management proposals, and the channel marking would likely reduce such incidents in Back Bay. As discussed above, some small water quality benefits to Back Bay would be realized by the reef balls and the elimination of the canal. The overall effect of the proposed project would be to reduce the potential water quality impacts associated with the marinas, resulting in some small net improvement to the ambient water quality of the Pine Island Aquatic Preserve. Shoaling and Scour Shoaling is generally the accumulation of unconsolidated sediments that occur because of their movement by hydrodynamic forces of water flow, waves and currents. Scour is a type of erosion that occurs when current forces, when moving around a structure, push sediments away. Petitioner's expert, Hans Wilson, testified that it would take a relatively extreme amount of wave energy to create scour at the bottom of the breakwater. He said that the proposed breakwater was similar to one used at Royal Palm Yacht Club in Charlotte Harbor, which has not caused shoaling or scour. Robert Brantly, of the Department of Environmental Protection, believes that the proposed breakwater could cause shoaling and scour. While not agreeing with Mr. Brantly's concern, Petitioner offered to place reef balls at the base of the breakwater to further dissipate wave energy. Petitioner's evidence on this issue lacked much detail, but the evidence offered by the District was speculation -- Mr. Brantly thought there might be a problem and wanted to see more information. The District failed to rebut Petitioner's prima facie case that the breakwater would not cause shoaling or scour. Public Uses The District and Intervenors contend that the proposed project would reduce access by the general public to the aquatic preserve because the boat ramps would be eliminated and the fishing platform would be smaller than the area now available to the public on the fishing pier. The evidence shows some small reduction in public access to the aquatic preserve would likely result from the proposed project. Fill The District and Intervenors claimed for the first time in their Joint Proposed Recommended Order that the proposed breakwater for the Charlotte Harbor marina is prohibited fill. Florida Administrative Code Rule 18-20.004(1)(c) prohibits "filling waterward of the mean or ordinary high water line." "Fill" is defined in Rule 18-20.003(27): "Fill" means materials from any source, deposited by any means onto sovereignty lands, either for the purpose of creating new uplands or for any other purpose, including the spoiling of dredged materials. For the purpose of this rule, the placement of pilings or riprap shall not be considered to be filling. The District claims that the breakwater is "clearly prohibited" and that no additional factual evidence needs to be presented to determine the issue. However, although it is clear that the rule prohibits the deposition of fill materials such as dirt or sand into the water, it is not clear what other activities are prohibited by the rule.3/ Docks and marinas are clearly allowed by the aquatic preserve rules. Whether the breakwater is a piling structure is not answered by the record evidence. Evidence regarding the practices of the Board of Trustees, the Department of Environmental Protection, and the District in the interpretation and application of the rule is also absent from the record. Therefore, even if the issue had been timely raised by the District and Intervenors, the record evidence is insufficient to prove their claim.
Recommendation Based on the foregoing Proposed Findings of Fact and Conclusions of Law, it is RECOMMENDED that the South Florida Water Management District deny the ERP and Lease requested by Petitioner. DONE AND ENTERED this 9th day of November, 2010, in Tallahassee, Leon County, Florida. S BRAM D. E. CANTER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 9th day of November, 2010.
The Issue The issue in this case is whether the Department of Environmental Protection (DEP) should grant the application of the City of Destin (City) and Walton County (County) for a Consolidated Joint Coastal Permit (JCP) and Sovereign Submerged Lands Authorization (Application) to restore a 6.9 stretch of beach in the City and County.
Findings Of Fact The Gulf of Mexico beaches of the County and City were critically eroded by Hurricane Opal in 1995. The erosion problem was identified by DEP, which placed the beaches on its list of critically-eroded beaches, and by the County and City, which initiated a lengthy process of beach restoration through renourishment (also called maintenance nourishment.)1 The process, which included an extensive studies2 and construction design, as well as pre-application conferences with DEP staff, culminated in the filing of the Application on July 30, 2003. The Application proposed to dredge sand from an ebb shoal (i.e., a near-shore) borrow area south of (i.e., offshore from) East Pass in eastern Okaloosa County, using either a cutter head dredge (which disturbs the sand on the bottom of the borrow area and vacuums it into a pipeline which delivers it to the project area) or a hopper dredge (which fills itself and is moved to the project site). On the project site, heavy equipment moves the dredged sand as specified in the design plans. The project is executed in this manner and progresses along the beach, usually at a pace of about 300-500 feet a day. Each day work is in progress, public access to the beach is restricted for a length of about 500-1000 feet in the immediate vicinity of the area of beach being worked. Water Quality Increased turbidity is the primary water quality concern in a project of this nature. Increased turbidity can adversely impact submerged seagrasses and hard-bottom habitat, along with the benthic communities depending on them. When sand in the borrow area is disturbed by dredging, sand and silt become suspended and increase turbidity to some extent and for some duration, depending primarily on the nature of the bottom material and the dredging method. (The cutter head dredge vacuums most if not all of the disturbed sand and silt into the pipeline while, by comparison, the hopper dredge would result in higher turbidity in the water in the borrow area.) Sand delivered to the project site via pipeline must remain suspended in water for transport. When the sand is deposited on the beach, the excess water, with suspended particulate matter, will drain off and return to the Gulf of Mexico. Even if hopper dredges are used, and if material is deposited on the project site other than via pipeline, some of the material will be deposited in the littoral zone, and some material deposited landward of the waterline will be inundated by the tides and wave action and potentially re-suspended in water in the littoral zone. If the water is turbid upon discharge in the littoral zone, the near-shore can become more turbid. Sand Quality The primary determinant of the amount and duration of turbidity generated in the borrow area and in the littoral zone of the project site is the quality of the bottom material in the chosen borrow area. The coarser the material, the less turbidity. The best quality bottom material usually is found in the kind of borrow area proposed for use in the Application. Sand in the borrow area came from some of Florida's finest beaches. It has been cleaned of fine material (silt) not only by wave action but also as the sand moved along shore in the littoral zone and by the currents in the East Pass inlet. Numerous tests of the bottom material in the proposed ebb shoal borrow for the project indicate that it generally has less than one percent silt. Expert witnesses for the City, County, and DEP testified that, with such low silt content, turbidity increases of no more than 5-10 Nephalometric Turbidity Units (NTUs) above background levels are expected at the edge of the mixing zone--150 meters down- current from the borrow area, and down-current and offshore from the discharge points on the beach. Moreover, they testified that turbidity levels are expected to return to background levels quickly (i.e., within an hour or so.) SOB and STBR questioned whether the experts could be certain of their testimony based on the test results. But SOB and STBR called no expert to contradict the testimony, and it is found that the expert testimony was persuasive. Standard Mixing Zone Initially, the City and County applied for a variance from the turbidity standards to allow them to exceed 29 NTUs more than 150 but less than 1660 meters down-current from the borrow area, and down-current and offshore from the discharge points, based on Attachment H, the Water Quality Impact analysis in the Application. The analysis was based on an assumption of five percent silt content in the bottom material in the borrow area. SOB and STBR attempted to use the five percent assumption to impeach the expert testimony on water quality. But when the quality of the bottom material was ascertained to be less than one percent, the variance request was withdrawn at DEP's request as being unnecessary and therefore inappropriate. SOB and STBR also argued in their PRO that, if a 1660-meter mixing zone was needed for five percent fines, then a 332-meter mixing zone would be needed for one percent fines. This argument was based entirely on counsel's arithmetic extrapolation. There was no evidence in the record from which to ascertain the validity of the extrapolation. In addition, the evidence was that the bottom material in the borrow area in this case will be less than one percent fines. Shore-Parallel Sand Dike Specific Condition 6 of the Draft Permit requires the permittee to "construct and maintain a shore-parallel sand dike at the beach placement area at all times during hydraulic discharge on the beach to meet turbidity standards prescribed by this permit." The shore-parallel sand dike is essentially a wall of sand built parallel to the shoreline to keep the sand slurry (the mixture of sand and water) being pumped onto the beach from washing back in the water, thereby giving the materials more time to settle out of the water before the water returns to the Gulf of Mexico. Even if this condition were not in the Draft Permit, the City and County would be required to build the dike since it is part of their design for construction of the Project. Turbidity Monitoring The Application included a proposal to monitor turbidity, and the Draft Permit includes the proposed monitoring as a Specific Condition 38. Every six hours during dredging and pumping operations, the City and County are required to sample 150 meters down-current of the borrow area, and down-current and offshore of the discharge point, and report the results to DEP within a week. In addition, Specific Condition 38 requires work to stop if turbidity standards are exceeded, which must be reported immediately. Work may not proceed "until corrective measures have been taken and turbidity has returned to acceptable levels." If more than one exceedence of the turbidity standard is reported, DEP will require the City and County to redesign the project to address and cure the problem. These conditions are part of the reasonable assurance that water quality standards will not be violated. Sediment Quality Control/Quality Assurance Plan Pursuant to Special Condition 4.b. of the Draft Permit, the City and County are required to do a Sediment Quality Control/Quality Assurance Plan, which requires them to measure the quality of the sand as it comes out of the pipeline before it can cause a turbidity problem. If the dredge hits pockets of bad material, which is not expected in this case, work could be stopped before it creates a turbidity problem. Absence of Natural Resources in Project Area DEP performed side-scan sonar tests in the vicinity of both the borrow site and near-shore in the Project area and determined that there were no hard bottoms or seagrasses in either area. Therefore, there are no natural resources within the project area that would be covered or placed in jeopardy by a turbidity plume. Reasonable Assurance Given For all of these reasons, the City and County have provided reasonable assurance that water quality standards will not be violated. Required Riparian Interest Generally, and in the beach nourishment project area, the BOT owns seaward of the mean high water line (MHWL). The City and County own some but not all of the beachfront landward of the MHWL.3 In anticipation of the beach nourishment project, the City and County had the MHWL surveyed as of September 7, 2003.4 The surveys state that the MHWL as of that date shall also be known as the ECL. The surveys also depict the landward and seaward limits of construction and the predicted post-construction MHWL. The surveys indicate that construction is planned to take place both landward and seaward of the ECL. The predicted post-construction MHWL is seaward of the ECL. By resolution, the BOT approved the surveys and established the ECLs for the Project. The City survey was approved, and ECL established, on December 30, 2004; the County survey was approved, and ECL established, on January 25, 2005. The BOT's decisions are being challenged in court. If the decisions are upheld, the BOT intends to file its resolutions and record the surveys. There was no evidence that the City and County have an easement or the consent of all of the other beachfront owners to undertake the proposed beach nourishment project. Some of the other beachfront owners do not consent, including members of SOB and STBR. Standing SOB was incorporated not-for-profit in Florida on January 28, 2004. STBR was incorporated not-for-profit in Florida on February 16, 2004. Both were incorporated to protect and defend the natural resources of the beaches, protect private property rights, and seek redress of past, present, and future unauthorized and/or inappropriate beach restoration activities. No evidence was presented by any party as to whether SOB and STBR have filed their annual reports with the Department of State, and no party filed a Department of State certificate of status as to either SOB or STBR. STBR has six members, all owners of beachfront property in the area of the proposed beach nourishment project.5 SOB has approximately 150 members. These members own approximately 112 properties in the City, approximately 62 of which are beachfront and the rest condominium units of beachfront condominium developments. However, it is not clear from the evidence how many of these beachfront properties are in the area of the proposed beach nourishment project (beyond the four owned by Linda Cherry, who testified). The testimony of Slade Lindsey was sufficient, together with member affidavits, to prove that all six members of STBR use the beaches and waters of the Gulf of Mexico adjacent to the Project area for swimming, fishing, boating, and/or enjoying beach and Gulf vistas. As a result, the construction of the Project will affect their interests at least during the time construction is taking place near their property. If the Project were to result in violations of water quality standards for turbidity, their interests would be affected as long as the violations lasted and perhaps longer if lasting damage to natural resources were to result. However, as found, there will not be any lasting damage to natural resources, and reasonable assurance was given that no water quality violations will occur and that exceedences of water quality standards in the mixing zone will be of short duration, lasting for no longer than an hour. These effects will not be substantial. The evidence was not sufficient to prove that construction of the Project will affect the interests of a substantial number of the members of SOB. First, it was not clear how many of them own beachfront property or even condominium units in developments adjacent to the Project area. Second, the only witness on the subject, Linda Cherry, does not know all of SOB's members and did not state how many of the 39 SOB members who signed affidavits as to their use of the beaches and waters of the Gulf of Mexico adjacent to the Project area are known to the witness. Even if a substantial number would be affected, their interests would be affected no more than the STBR members' interests.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that DEP enter a final order issuing Draft Permit DEP JCP File No. 0218419-001-JC. DONE AND ENTERED this 30th day of June, 2005, in Tallahassee, Leon County, Florida. S J. LAWRENCE JOHNSTON Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 30th day of June, 2005.
The Issue The issues in this proceeding involve whether the Respondent, St. Joe Paper Company ("St. Joe"), is entitled to a "dredge and fill permit" authorizing it to construct a marina for recreational boats, containing 84 boat slips, along the eastern shore of the St. Johns River in St. Johns County, Florida. Embodied within that general consideration are issues involving whether St. Joe, in the construction and operation of the marina, can comply with water-quality parameters embodied in Chapter 17- 3, Florida Administrative Code, for Class III waters of the State, Section 403.918(1), Florida Statutes, as well as the public interest standards of Section 403.918(2), Florida Statutes, and the standard concerning "cumulative impact" embodied in Section 403.919, Florida Statutes.
Findings Of Fact The applicant, St. Joe, seeks to construct and operate a recreational boat marina, consisting of a single, main pier, 12 feet wide and extending some 850 feet waterward in a westerly direction from the shoreline of the east bank of the St. Johns River in St. Johns County, Florida. The main pier will join a terminal pier extending approximately 575 feet in a general north/south direction parallel to the shoreline of the St. Johns River, perpendicular to and abutting the longer main pier. Extended in a landward or easterly direction from the terminal pier structure will be four (4) individual "finger piers" ranging from 119 to 305 feet in length. Located along the individual piers and along a portion of the main pier near the waterward end of it will be 84 slips for recreational-type boats. Additionally, a breakwater system will be suspended along the outer perimeter of the terminal pier and northernmost and southernmost individual piers in order to reduce wave action and its effect on boats in the interior of the marina. Additional details concerning the marina design and operation are contained in the findings of fact below. The Site The site of the proposed marina is on the eastern shore of the St. Johns River in St. Johns County, Florida. At that point, the St. Johns River is almost two miles wide, being approximately 10,000 feet from shoreline to shoreline. The proposed marina site encompasses approximately 1,100 linear feet of river bank frontage. All of the adjacent upland property is owned by St. Joe, and St. Joe owns extensive additional river frontage to the north and south of the marina site. The nearest properties not owned by St. Joe are located 3,500 feet to the north of the site and 1,500 feet to the south of the site. The site is located approximately two miles north of Hallowes Cove, a relatively pristine, diverse and productive marine habitat. The site is characterized, landward of the terminal end of the pier and waterward of the upland, by an unvegetated "near shore area or tidal zone" which extends approximately 50 feet from the mean high-water line of the river to the mean low-water line. Waterward of this zone and extending to a depth of approximately two feet is a system of grass beds, (vallisnerida), commonly known as "tape grass". The grass beds extend approximately 200 to 250 feet from the shoreline. Waterward of the grass beds is an unvegetated area with a gradual slope to a depth of approximately six feet. From the six-foot contour of the river bottom, a relatively precipitous slope begins, extending to depths which exceed 19 feet. In this zone, there are no grass beds. Further waterward and extending beyond the most waterward extent of the the marina site, the river bottom rises somewhat to depths of 13 feet, 12 feet and 11 feet, in the direction of the center of the river. The river bottom substrate in the area of the marina is composed primarily of sand. This includes some shell and other coarse materials, with minor amounts of silt. In fact, organic silt is a very small portion of the bottom sediments, consisting, at a depth of four and one-half feet, of less than 1% silt and at a depth of 15 feet of less than 6% silt content. The present water quality prevailing at the marina site is good, and the benthic habitat in the general area is healthy and diverse. The most landward boat slips proposed at the marina will be located at a distance of approximately 275 feet from the most waterward extent of the grass beds. These most landward slips will be located in depths of approximately eight feet. Access to the marina will be from the north and south in defined channels marked on the west by the end of the individual piers and on the east by channel markers located at the depth contour of minus six feet. That is, the six-foot depth will be the most shallow portion of the channel marked by the channel markers, so that boats will not be permitted to navigate the shallower portion landward of the channel markers insofar as the marina's enforcement program can insure that. The approximate width of the northern channel is 75 feet, and the width of the southern channel is 50 feet. Due to the precipitous drop in depth beyond the contour of minus six feet, the average depth of the channels is 10 to 12 feet. The majority of the boat slips, as well as the basin of the marina, will be located in depths of between 10 and 18 feet. The consultant and expert witness who designed the marina, Erik Olsen, established that the length of the main pier and the location of the most landward of the boat slips and the location of the channel markers are all part of a design and plan intended to insure that marina and boat activity within the marina occur well beyond the extant grass beds and waterward of depths of six feet, to insure that no damage to the grass bed habitat area is occasioned by propeller scouring, "prop-wash", or grounding of boats. Other design measures are also intended to preclude boaters from entering the shallow depths and grass bed areas. Two tiers of signs will be located between the marina basin and the most waterward extent of the grass beds. First, regulatory buoys and signs are proposed to be located at the contour of minus four feet and will establish a "manatee protection zone" landward of that contour. The evidence reveals, however, that a safer contour for the manatee protection zone boundary to be established by the applicant would dictate placing the regulatory warning signs concerning the manatee protection zone at the same contour, minus six feet of water, where the channel markers will be located. This is because the marina will serve boats of up to 4.5 feet in draught. Secondly, a tier of signs will be located approximately ten feet waterward of the most waterward extent of the grass beds warning boaters that aquatic grass beds exist landward of the signs and that prop dredging and boat operation is prohibited. Such warnings at the locations found above should be mandatory conditions to any grant of the permit. A specific, agreed-upon condition is already in the draft permit issued by the Department prescribing the size and lettering of these signs and other design details. A railing will extend, as proposed by the applicant, along the main pier between the slips and the shoreline to discourage boaters from mooring along the main pier, landward of the slips. The evidence establishes that in order to more adequately insure protection of the manatee habitat area and the grass beds, a mandatory condition in boat-slip rental leases should be inserted to absolutely prohibit boaters from mooring along the main pier, landward of the boat slips. Because of the currents and significant water depth prevailing at the marina site, the marina construction will require no dredging nor will operation and maintenance of the marina require any dredging on a continuing basis. Additionally, in the interest of protecting water quality, no fueling facilities or boat fueling will be permitted at the marina at all; and the grant of a permit should be mandatorily conditioned on this basis. Neither will any boat maintenance or repair be permitted at the marina, including no hauling of boats or scraping or painting of boat bottoms. This condition should be clearly pointed out to users of the marina by appropriate warning signs regarding the prohibition against boat maintenance and repair, including warnings concerning the proper methods of disposal of used oil and other petroleum products. The marina will feature pump-out facilities for boat heads and bilges. The pump-out facilities will consist of a central pumping system in which waste is removed from the boats, transported by pipeline to an upland, central waste water collection and treatment system. No holding tanks or other storage of wastes will be located at the piers. The pump-out facility will serve not only the boat heads but also boat bilges in order to prevent contaminants, such as oil and boat fuel from entering the State waters involved. The piers will feature trash collection containers of appropriate number, size and location on the piers so as to provide convenient trash disposal for each boat slip. The piers will also feature plastic modular dock boxes to preclude boaters from randomly storing materials and equipment on the piers. No fish cleaning will be permitted on the piers at all, but rather must be accomplished on the uplands, with disposal of related wastes in the upland collection system. A "no wake" zone will be established in an area extending 500 feet north and 500 feet south of the marina. The "no wake" zone will be marked pursuant to requirements of the Florida Marine Patrol. The marked "no wake" zone should also extend waterward of the farthest waterward extent of the marina, as well as 500 feet north and south of it. Only private, recreational boats will be moored at the marina. All commercial boats will be prohibited. The marina will serve a Yacht Club to be developed by St. Joe in conjunction with the marina. Only members of the Yacht Club and their guests will be permitted to use the marina. This will assist with enforcement of the various conditions on marina operation and maintenance by the owners as to the boat-slip lessees and their guests. This and all other conditions should be enforced by mandatory restrictions in the boat-slip leases. Likewise, the applicant has agreed to permit no "liveaboard" boats at the marina in order to avoid the possibility of sewage or other contaminants entering the State waters from liveaboard boats. The upland facilities will include restrooms, and signs should be appropriately placed on the piers to advise boaters and boat owners and operators of the availability of restroom facilities. The marina will not feature fueling facilities; however, St. Joe will maintain pollution containment supplies and equipment at the marina sufficient to contain any potential fuel or other petroleum spills from catastrophic events, such as the rupture of a boat fuel tank. Expert witnesses for St. Joe established that a "management and operational plan" designed to enforce the provisions enumerated above will be enacted by the applicant. The management and operational plan includes three mechanisms of enforcement: Warning signs. Boat-slip lease agreements which must incorporate all restrictions found to be necessary herein. These will contain an enforcement provision providing for mandatory eviction from use and lease of the marina facilities for any breach of those conditions by lessees or their guests. Management personnel will be employed on the marina property to enforce all restrictions and conditions designed to insure environmentally-safe operation and maintenance of the marina, and such personnel should be employed during all operating hours of the marina, not just during daylight hours, as proposed by the applicant. Signs will be posted at conspicuous locations at the marina and at the upland facilities of the Yacht Club informing boaters of the marina rules and prohibitions. The signage will be visible to Yacht Club members and their guests using the marina, and members' guests will be required, upon mooring at the marina, to register and to review the rules and prohibitions. Boat-slip lease agreements at the marina will incorporate these marina rules and prohibitions. Under the lease agreements, a violation of the marina rules or prohibitions by a member or guest will be considered a breach of the lease and will result in revocation of the lease and removal of the member's boat from the marina. A dock master will be employed at the marina to supervise the operation and maintenance of the marina and will be assisted by dock hands and other personnel in order to see that the conditions and restrictions referenced herein are enforced. The applicant has proposed such personnel being employed during daylight hours. However, in order to insure that the standards for operation and maintenance of the marina and boats using it will be enforced so as to avoid water-quality violations and violations of the public interest parameters delineated below, the permit grant should be conditioned upon such personnel being employed during all operating hours of the marina, whether daylight hours or not. If this is accomplished, the enforcement mechanisms outlined in the management and operational plan will reasonably insure enforcement of the marina's rules, prohibitions and conditions on any grant of the permit and likewise reasonably insure that water-quality and public interest standards are not violated. Upland Facilities The upland and Yacht Club facilities to be developed in conjunction with the marina will be located on approximately seven acres adjacent to the marina site. The Yacht Club and related facilities will include a clubhouse, parking, and a storm water treatment system which will serve the upland facilities. St. Joe has obtained a conceptual permit for the management and storage of surface waters for the proposed upland improvements, including the Yacht Club. It will also seek a permit for the storm water treatment system, itself. St. Joe, through its consultants, has investigated and opined that the installation of the proposed upland facilities are feasible and can comply with applicable regulatory criteria and is pursuing the necessary permits and approvals from local governments and state agencies. It will insure that all such is accomplished prior to initiation of construction of the Yacht Club facilities. The precise configuration and design of all upland facilities will be dictated by applicable local ordinances and the requirements of State regulatory agencies. Marina Impacts The applicant/Respondent and the Petitioners are in essential agreement, through the testimony of their witnesses, regarding the general potential impacts which may be posed by marinas in a general sense, when located in proximity to environmentally-sensitive areas. Concerning anticipated impacts of this marina at the subject site, however, St. Joe presented the testimony of three expert witnesses, as well as a hydrographic study. It was thus established that violations of the pertinent water-quality statute and rules and the public interest standards contained in the statute referenced herein will not be violated. The Petitioners, although presenting both lay and expert testimony regarding the water quality and habitat type and quality in the general area of the site and the general impacts that can be caused by marinas in such areas, presented no expert testimony or studies regarding the anticipated impacts of this particular marina, as designed and configured by the applicant, on the subject site and aquatic habitat. Water Quality Considerations Marinas are potential sources of pollutants which may adversely impact water quality. Different sources at a marina may generate different pollutants; and in this case, testimony addressed these potential pollutant impacts. The totality of the expert testimony taken at hearing establishes that the marina will not likely cause a violation of applicable water-quality standards. One witness for the Petitioners, Bill Watkins, was accepted as an expert in water quality. In describing potential impacts of the marina, however, he only opined that there "could be some effect on water quality"; however, he did not specifically establish adverse effects on water quality which could be anticipated or reasonably expected regarding violations of applicable standards. Mr. Watkins acknowledged: "As to whether or not that degree of pollution, and that's what we're talking about, degree of impact, would be something that would be, have a significant degradation effect, I could not answer without further site specific studies." Mr. Watkins further described the type of site specific information which would be required for him to make a proper assessment of water-quality impacts, including hydrographics and the nature of the sediments existing at the site. Other witnesses for the Petitioners similarly declined to opine regarding violations of the water-quality standards because site specific information was not available to them. Dr. DeMort, for example, explicitly declined to offer an opinion regarding water-quality violations. The opinions and testimony of the expert witnesses on water quality presented on behalf of St. Joe, as well as by the Department, are accepted in establishing that no water-quality violations by the construction and operation of the marina are anticipated. The reasonable assurance that water-quality violations will not occur through the construction and operation of the marina is illustrated by the unrefuted evidence concerning the hydrographics by which the site is characterized. A knowledge of site hydrographics is necessary to accurately determine potential water-quality impacts. A hydrographic study was prepared by St. Joe through the auspices of its consultant, Olsen Associates Incorporated. The experts who prepared that study testified on behalf of St. Joe at hearing, and a Department witness who reviewed the study testified by deposition. None of the Petitioners' expert witnesses addressed the subject of site hydrographics other than to note that they were an important consideration. Mr. Buckingham was accepted as an expert witness in the area of marine engineering with emphasis on hydrographics. He testified regarding the hydrographic study prepared and submitted by St. Joe. The study involved the collection of data at the site, including the gauging of water surface elevations over a two-day period in December of 1988; the comparison of those elevations to predicted elevations based upon historical data; a measurement of current velocities at the site; a dye study to assess the flow regime at the site; and the gathering of depth soundings and sediment samples to confirm the bathymetry and nature of bottom sediments at the site. The hydrographic study also involved the analysis of the data collected at the site. Hydrographics at the site are composed of two components, the transport of a pollutant by advective currents and the dispersion or diffusion of a pollutant within the water column. The physical transport by advective currents dominates the hydrographic circumstance prevailing at the marina site. A pollutant introduced at the site is more likely to be physically transported away from the site, in addition to being merely dispersed through the water column at the site. This is because of the relatively high current velocities prevailing. Both the transport and dispersion components were analyzed in the study to determine the time and distance necessary to reduce an initial concentration of a hypothetical pollutant to 10% of its initial concentration. A pollutant introduced at the site would be reduced to 10% of its initial concentration in less than seven minutes and within 400 feet of the site on the ebb tide and within 300 feet of the site on the flood tide. Moreover, the "plume" of this hypothetical pollutant would occur in a longshore direction parallel to the shore, as opposed to a direction toward the shore and would be of comparatively narrow width (approximately 30 feet). The hydrographics of this site are such that a complete water exchange will occur in 20 to 30 minutes at any point during the tidal cycle. The evidence thus demonstrated that the site is extremely well flushed by tidal currents. In his deposition, Ken Echternacht, of the Department, testified that data in the hydrographic study was realistic in his experience and that he had no questions or concerns regarding the data and methodology used to confirm that data. In addition to Mr. Buckingham's testimony and the study, itself, the testimony of Dr. Echternacht established that flushing is of no concern and is thoroughly adequate at the site. Dr. Echternacht is the Department's hydrographic engineer, whose function is to review all dredge and fill permit applications which may have impacts upon the hydraulics of surface water systems. He has reviewed approximately 1,500 dredge and fill permit applications. His testimony and that of Mr. Buckingham is accepted, as is that of other Department expert witnesses in establishing the excellent flushing characteristics of the site and that the construction and operation of the marina will not adversely affect the present hydrographic situation at the site, as that relates to establishing that no water quality violations will occur. All marinas are potential sources of pollutants. The first to be addressed involves the installation of the pilings themselves during the construction of the marina. This is a potential source of turbidity. Turbidity involves the suspension of bottom sediments and substrate material in the water column, which can pose, among other problems, the retardation of light penetration through the water column which can have an adverse impact on photosynthesis in marine grass beds. In extreme cases, it can cause the destruction of grass beds through killing of the grass by lack of adequate light penetration, as well as the smothering effect of sediments being deposited upon grasses. The method to be used by St. Joe in installing the pilings will be by "jetting" them into the bottom of the river initially and then driving the pilings into the river bottom to the required depth to support the piers. Witnesses for St. Joe and the Department established that this method will constitute an adequate safeguard to be employed during construction to minimize any turbidity. Any temporary or local turbidity caused by the installation of the pilings will be transitory and will pose no significant water-quality violation; however, turbidity curtains will, be employed, if necessary, by the applicant to control any such turbidity during construction. Another potential source of turbidity at a marina involves the dredging, washing or disturbance of the river bottom caused by boat propellers or boat keels. The evidence demonstrated that the risk of such "prop dredging" or wash at this marina will be negligible due to the design features and conditions at the site, including the channels and channel markers, and particularly by the depth of waters prevailing at the site. The marina basin and boat slips are located in water of sufficient depth to prevent prop dredging or wash. The =average depth of the entrance channels is between 10 and 12 feet. Maneuvering within the marina basin will occur in depths of 10 feet or greater. Although the most landward boat slips are located in depths of approximately eight feet, the average depth within most slips is approximately 10 to 12 feet. These depths are based upon the bathymetric survey of the site and confirmed by random soundings performed during the course of the hydrographic study in evidence. Further, these depths are "mean low water" depths. Mean low water reflects the "lowest expected level" within a 29-day tidal epic. The "mean lower low" level is the lowest expected level over the course of a year. That level prevailing at the site, according to the study, is 0.1 feet lower than mean low water. The maximum draught of boats expected to be moored at the marina is 4.5 feet. Thus, the depths in the marina will allow ample clearance between propellers and keels and the river bottom. The required clearance between boat bottoms and propellers and the river bottom can further be assured by proper placement of boats in the boat slips in the leasing process and in the assignment of boat slips to casual, temporary users of the marina. In other words, the larger boats will be assigned to the deeper, more waterward slips. Other measures include warning signs, which should be placed along the six-foot depth contour, along the landward edge of the entrance channels and beyond the waterward extent of the grass beds. This will insure that boaters do not stray into shallow-water, aquatic habitat areas. A second factor in determining the potential for prop dredging at the marina is the nature of the sediments themselves. Four witnesses, including those testifying for the Department and for the Petitioners, established that the sediments at the site are primarily sand-based, with minimal organic silt content. The sandy nature of the sediments minimizes the potential for turbidity caused by prop dredging or prop washing (hydraulic currents created by propeller operation) because sand, by its density, mass and weight, tends to settle out to the bottom much quicker if it is suspended in the water column. Even if prop dredging did occur at the marina, generating turbidity, the high flushing characteristic of the site would quickly transport and disperse any such turbidity and render it undetectable and likely prevent its deposition on the grass beds. A potential source of pollutants at a marina is boat fuel. Expert witnesses for the Department and the applicant established that the design and operational features of the marina, primarily the absence of any fueling facilities, will minimize or eliminate the potential for pollutants generated by fueling operations. Another potential source of pollutants at a marina is waste from boat heads and bilges generated by flushing boat heads or pumping out of bilges with bilge pumps. Expert witnesses for St. Joe, as well as the Department, established that the design and operational features with which this marina will be characterized will minimize or eliminate the potential for such pollutants to be generated because liveaboard boats will be prohibited, and the pumping out of heads and bilges will also be prohibited because of the conditions agreed to by the applicant for a grant of this permit. Another potential source of pollutants at a marina is the use of anti-fouling paint used on the bottoms of boats and the periodic scraping and repainting of boats. Expert witnesses for the Department and the applicant established that the operational features and design of this marina will minimize the potential for pollutants from this source because boat painting, sanding, and scraping and other operations attendant to boat painting will be absolutely prohibited at the marina. Finally, another potential source of pollutants would be trash and garbage materials. The potential for pollution from this source will be minimized by the use of trash containers and dock boxes located at frequent intervals around the piers and boat slips, as well as the instructional signs to be placed on the piers and slips by the applicant and the publication of marina rules in order to inform boat operators and guests of the necessity to dispose of trash in the proper containers. It has thus been established that the design and operational characteristics of the marina and conditions to be imposed thereon will minimize or eliminate the potential for pollutants to be generated and placed in the surface waters at the site. The marina will not occasion violations of applicable water-quality standards. Any pollutants which might be deposited in the surface waters at the site will be quickly transported and dispersed so as to be undetectable at the marina or in the vicinity of the marina because of the critical role played by the hydrographics prevailing at the site. Public Interest Impacts Much of the testimony at hearing regarding impacts upon the various public interest standards, including wildlife and habitats, focused upon the grass beds, and the benthic communities prevailing in deeper water at the site, as well as the fact that the site is used by manatees. Dr. Quinton White was accepted as an expert in biology and biological impacts of marina construction and operation. He testified on behalf of the applicant. His testimony and that of other expert witnesses offered by St. Joe and the Department established that there would be no adverse impact on benthic communities and organisms, including manatees, caused by the construction and operation of the marina. The Petitioners called expert witnesses on the issue of impacts on wildlife. Mike Allen, a Florida Game and Fresh Water Fish Commission staff member, testified that he was not really qualified as an expert in fisheries or benthic communities but, rather, in terms of terrestrial species which are not involved in this proceeding. Lawson Snyder, another Florida Game and Fresh Water Fish Commission staff member, was accepted as an expert in fisheries biology on behalf of Petitioner but testified that the marina's impacts upon fish and wildlife would not be detectable. Jim Valade, a Florida Department of Natural Resources staff member, was also accepted as an expert in marine biology, including fish and manatees, but testified that the permit applicant has taken steps to protect manatees in virtually all aspects and that his department's concerns regarding the safety of manatees have been adequately addressed by the design and proposed operation of the marina. Bill Watkins, a St. Johns River Water Management District staff member, was accepted as an expert in biology, but testified that the design of the marina provides the grass beds "a fair degree of protection" and declined to opine that the marina would have any adverse impacts upon wildlife or fish. Finally, Dr. Carol DeMort, in her deposition, specifically declined to render any opinion regarding adverse impacts upon wildlife or fish. Thus, the evidence adduced by the Petitioners at hearing did not rebut the evidence introduced by the applicant that the marina will have no detectable impacts upon wildlife or habitats involved in the vicinity of the site St. Joe introduced evidence concerning impacts from shading upon grass beds by the marina structures themselves and from turbidity "washed" onto, the grass beds by motorized boats maneuvering in the marina basin. Expert testimony was adduced that established that shading caused by the widest pier, that is, the main pier with a width of 12 feet, would have no adverse impact on the grass beds due to shading. That testimony was unrebutted and is accepted. Two expert witnesses for St. Joe, a marine engineer and a biologist, as well as a Department witness, established that, even assuming that turbidity was generated by propeller action in the marina basin, the turbidity resulting from prop wash would not be transported 275 feet from the marina basin offshore to the :grass beds at the inshore area. They attributed those opinions to the nature of the sediments involved which are not readily suspended, the flushing at the site, the distance between the basin and the grass beds, and the typical extent of prop wash from boats expected to be used at the marina. The Petitioners presented two witnesses, who testified regarding the impacts of prop wash. Mr. Allen, an expert in upland terrestrial species, testified regarding the potential for deposition of sediments on grass beds but also acknowledged that the hydrographics at the site, the distance between the marina basin and the grass beds and other protective measures would minimize this potential. One lay witness for the Petitioners testified to the effect that if a "handful" of boat owners in the marina violated the "no wake" restrictions and accelerated their boats in violation of those restrictions, they would cause turbidity to be placed upon the grass beds. His testimony was contradicted, however, by a marine engineer, who testified that prop wash is a function of many parameters (e.g., the RPM of the engine, the horsepower of the engine, the draught of the boat, and configuration of the propellers, etc.). He established that it would not be reasonable to expect prop wash extending twice the length of a boat. Regarding impacts upon benthic communities at the site, the applicant introduced expert testimony which established that the benthic communities in that vicinity of the marina, including the grass beds, fin fish, shellfish, and other organisms, will not be adversely impacted by the construction and operation of the marina in light of the safeguards which would be imposed upon the permit, as delineated herein. This is primarily due to the absence of significant concentrations of pollutants to be expected and the hydrographics prevailing at the site as that relates to the unlikelihood of boat grounding, prop dredging, and prop wash suspending pollutants and turbidity and depositing them on benthic community habitat areas. Only one of Petitioners' witnesses, Dr. DeMort, testified in her deposition concerning potential impacts upon benthic communities. Dr. DeMort made it clear, however, that she had conducted no investigations and studies necessary to enable her to render an expert opinion on the impacts upon the benthic communities prevailing at the site which might be caused by the marina's construction and operation. Her testimony in this regard only related to marina installation and operation in general and was not related to the specific design characteristics and proposed operational parameters of the subject marina. Manatees are an endangered species. There is much concern about their welfare with regard to the proposed project because all parties acknowledge that the site and the shoreward grass bed areas, particularly, are frequented by manatees, particularly for summer foraging. Manatees tend to forage in shallow waters and associated grass beds. Boats pose definite hazards to manatees and cause significant manatee deaths each year due to impact from boats, as much as 15% to 30% of the known population. In response to this hazard, the U.S. Marine Mammal Commission has recommended that grass beds be protected and that establishment of protective or "no wake" zones in manatee foraging areas be accomplished. In light of such restrictions voluntarily agreed to by St. Joe and its expert testimony in this regard and in light of the manatee education and awareness measures proposed by the applicant, it has been demonstrated that the marina will not have any negative impact on the manatee population in the area. The Petitioners' only expert witness concerning manatees, Jim Valade, indeed, opined that the marina had taken steps to protect manatees "in virtually all aspects". In this connection, the design features in the management and operational plan discussed herein and proposed by the applicant embodies measures to address potential impacts upon manatees which frequent the marina site. These include manatee awareness signs to be posted at the marina; and an additional specific condition has been agreed upon by the Department and the applicant which specifies the size, lettering and other details of the warning signs, and the location of them within the marina, all of which will be included in a plan to be submitted to, reviewed, and approved by the Florida Department of Natural Resources. Additionally, a permanent educational display will be located at the Yacht Club informing boaters who frequent the facility of the presence of manatees in the area and the need to minimize the impact of boats upon manatees. During construction, if a manatee is sited within 100 yards of the marina site, construction activities will cease and not resume until manatees have left the area. A handbook will be prepared concerning manatees and the effect on them of boat operation, which will be distributed to employees of the facility and to Yacht Club members and guests. This requirement and the review of it by Yacht Club members and guests will be an integral requirement in the terms of the slip leases. Additionally, no docking facilities, pilings or cleats will be located along the portions of the piers not containing boat slips in order to discourage boaters from attempting to moor at those locations, which will reduce the number of boats frequenting the marina, as that relates to manatee safety. This portion of the St. Johns River functions as a highly productive juvenile fish nursery and sports fishing area. Therefore, an examination of the marina's potential impacts upon marine productivity, fishing and recreation in the area is an important consideration in this proceeding. The discussion of this potential impact involves the same issues discussed in connection with impacts upon water quality and wildlife habitat; namely, the generation of pollutants and the impacts upon the grass beds and benthic communities directly by boat operation itself. Unrefuted testimony adduced by the applicant and the Department has established that impacts upon the fish population and upon marine productivity, fishing and recreational values will not be adverse. No deliterious effect is likely to be occasioned the fisheries and fish habitat and the habitat of other aquatic organisms in terms of juveniles or adults or to the sport fishing values of the area in which the marina will be located. Indeed, the marina structures and the shade and concealment offered by moored boats will provide additional habitat for juvenile fish, as well as provide an additional source of food because of the "fouling communities" of life forms which will be expected to grow on the pilings. These will serve as food for juvenile fish and some species of adult fish which, in turn, will enhance the food supply of predatory fish operating at an upper level in the food web. The boats and structures themselves also will operate as a source of protection for certain fish populations from predators. The Petitioners produced a fisheries biologist as an expert witness, who testified in this regard; but he acknowledged that he did not know whether noticeable impacts on conservation of fish, marine productivity and recreational values will be caused by the installation and operation of the marina. He testified in a general sense that he feared some negative impacts might result but did not feel that any such impacts would be detectable based upon testimony he heard and deferred to, including testimony that the littoral zone would not be impacted by the marina to any significant degree. He ultimately opined that the marina would likely have little impact on sports fishing. The other witness produced by the Petitioners concerning impacts upon fishing and recreational values was unable to render any expert opinion, by her own admission, because she had conducted no studies or otherwise been provided information regarding the design and proposed operation of the marina. Consequently, the testimony adduced by the applicant as to these parameters is accepted; and it has been established that the marina will not adversely impact fisheries, fish conservation, aquatic habitat, sport fishing, recreational values and marine productivity in the area involved at the project site. Regarding potential impacts upon the public health, safety and welfare and property of others, the applicant and the Department adduced expert testimony that no adverse impact regarding these interests will occur. The testimony of Petitioners' experts similarly establishes that the marina would not pose safety hazards or would otherwise give rise to any noticeable impacts upon the public health, safety, welfare and property of others. Regarding potential impacts upon navigation or the flow of water, St. Joe and the Department introduced expert testimony to establish that the marina would not adversely impact navigation or the flow of water, and it is so found. The Petitioners' introduced no evidence regarding this subject. Regarding potential impacts upon significant historical and archaeological resources, the applicant and the Department introduced evidence that no adverse impact as regards these resource parameters will occur. Although one of the Petitioners, in her testimony, speculated that the marina could "detract" from the William Bartram scenic highway, she was unable to specify how the marina would impact the highway or to what extent the highway was a significant, historical or archaeological resource. It is found that no such adverse impact on the William Bartram scenic highway will occur. Cumulative Impact Regarding cumulative impacts, the applicant and the Department introduced evidence that the marina would not give rise to impacts which, cumulative with the impacts of other marina facilities, would be significant. The evidence establishes that there are six marinas within four miles of this marina site; two upriver, and four downriver. Due to the hydrographic circumstances in the area and the distance of the other marinas from this site, it has been demonstrated that the addition of this marina to the area will not result in any adverse cumulative impacts. Mr. Mike Allen, the expert in upland terrestrial species (not involved in this proceeding), referenced in his testimony the cumulative impacts he feared on sports and commercial fishing. Mr. Allen made it clear, however, that his reference was not to cumulative impacts caused by the marina and existing marinas but, rather, to impacts which could be brought about by many such future facilities located in this particular area. The evidence does not reflect, however, that any other marinas are conceptually contemplated or are the subject of other permit applications for this area for the future. It is thus found that no significant adverse cumulative impacts will be occasioned by the installation and operation of the subject facility.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that the application of St. Joe Paper Company for the dredge and fill permit at issue be granted, provided that the terms and conditions enumerated in the Department's Intent to Issue, in evidence as St. Joe Exhibit 9, and accepted by the applicant, as well as those conditions found in this Recommended Order to be necessary and supported by the evidence, are incorporated in the permit as mandatory conditions. DONE AND ENTERED this 26 day of October, 1990, in Tallahassee, Leon County, Florida. P. MICHAEL RUFF Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 29 day of October, 1990. APPENDIX TO RECOMMENDED ORDER IN CASE NO. 89-5053 Applicant's/Respondent's Proposed Findings of Fact 1-53. Accepted, but are subordinate to the Hearing Officer's Findings of Fact on the same subject matter, particularly in those several instances where conditions on the grant of the permit have been recommended to be modified somewhat by the Hearing Officer in light of the totality of the preponderant evidence presented. Rejected, as unnecessary. Accepted. Respondent DER's Proposed Findings of Fact The Department submitted no proposed findings of fact but, rather, adopted those submitted by the applicant/Respondent. Petitioners' Proposed Findings of Fact Petitioners, Hoffert, presented no proposed findings of fact but, rather, a letter in the nature of final argument which has been referenced and discussed in the above Preliminary Statement to this Recommended Order. Petitioners, Cornwell, submitted a post-hearing pleading; but it contained no specific, separately-stated proposed findings of fact, which can be separated from their mere recitation and discussion of testimony in evidence and arguments such that coherent, specific rulings could be made. Petitioners, Cornwell's post-hearing pleading did not conform to the instructions given to them by the Hearing Officer at the conclusion of the hearing concerning the appropriate manner for submission of proposed findings of fact, and they were submitted late. They have been considered in the rendition of this Recommended Order, however, in spite of the fact that they were filed in a tardy fashion. COPIES FURNISHED: Dale H.

Findings Of Fact The Petitioner owns property which is adjacent to Lake Serena in Putnam County, Florida. Through his application to the Respondent, the Petitioner is seeking to dredge an area waterward of the ordinary high water line of Lake Serena, and to place the dredged material on another area waterward of the ordinary high water line. The purpose of the proposed dredging and filling is to create a more gradual shoreline sloping from the Petitioner's residence to the shore of Lake Serena. Petitioner proposes to cover the filled area with white sand. He proposes to use the area as a sandy swimming beach. The area which the Petitioner is proposing to dredge and fill is presently dominated by wetlands vegetation, which would be removed by the dredging activity. The Petitioner originally commenced his project without receiving any permit from the Respondent. A large amount of the wetlands vegetation has already been removed. Lake Serena is a relatively pollution-free lake. Much of the littoral or transitional zone vegetation surrounding the lake has been replaced by sandy swimming beaches. Only approximately forty percent of the shoreline is now an aquatic vegetated littoral zone. Aquatic vegetation in the littoral zone surrounding Lake Serena serves an important natural function in preserving the water quality in the lake, and in preserving the natural resources of the lake, including fish and wildlife. The aquatic vegetation serves to filter run-off from uplands areas by assimilating nutrients that are in the run-off. A nutrient scale has been devised for identifying the amount of nutrients in a lake. An oligotrophic lake is low in nutrients. A mezotrophic lake has a moderate amount of nutrients. A eutrophic lake is high in nutrients. In the natural process of aging, water bodies progress from oligotrophic to a eutrophic state. This is a very long natural process taking thousands of years. Lake Serena is an oligotrophic lake. Aquatic vegetation in the littoral zone surrounding Lake Serena serves to maintain this condition. If too much aquatic vegetation is removed from the littoral zone, a buildup of nutrients would result. This buildup of nutrients would cause an algal bloom, or a buildup of algae plants on top of the lake. A buildup of algae on the lake would drastically decrease the oxygen level of the lake. This is because algae itself uses oxygen, because algae kills oxygen producing plants which thrive on the bottom of the lake due to light being cut off, and because, as the algae dies, it sinks and decomposes using up more oxygen. An algal bloom, and the resulting reduction of oxygen levels in a lake would constitute pollution. Removal of aquatic plants in Lake Serena's littoral zone would serve to diminish fish and wildlife populations in the lake. Small fish use such an area as a nursery ground where they can hide from predators. Without such a nursery ground, the cycle of survival for aquatic wildlife would be cut off. The area from which the Petitioner has already removed considerable wetlands vegetation, and proposes to remove more, is a viable part of the littoral zone of Lake Serena. The area serves the beneficial purposes set out in Paragraph 2 above. It cannot be determined with any degree of certainty that the Petitioner's proposed project would have any finitely measurable impact upon water quality or wildlife resources in Lake Serena. Certainly removal of all such littoral zones would drastically change the ecology of the lake and render it polluted. Sixty percent of Lake Serena's shoreline has already been denuded of vegetation. Although it cannot be determined precisely how much more such action the lake will tolerate, it is clear that there is a limit. If the Petitioner's project were granted, other similar projects would also be justified. Inevitably the lake's oligotrophic nature would be destroyed. The only effect that the Petitioner's project could have upon the water quality and natural resources of Lake Serene is negative. No evidence was offered at the hearing from which it could be determined that the Petitioner's proposed project would not have an adverse impact upon the water quality and natural resources of Lake Serene. In its notice of intent to deny, Respondent asserted that the proposed project would be expected to degrade the water quality of Lake Serena, and to violate water quality standards because turbidity levels would exceed permissible limits. Respondent is contending that during the pendency of the project turbidity levels will be too high. At the present time the water level of Lake Serena is two to three feet below the ordinary high water line. The area Petitioner proposes to dredge and the area he proposes to fill, while below the ordinary high water line, are above the present water line. From the evidence it appears that steps could be taken so that the proposed project could be accomplished without exceeding permissible turbidity levels. The only purpose that would be served by the Petitioner's proposed project is to provide Petitioner with a sandy swimming beach rather than a natural shoreline.
The Issue The issue here concerns the entitlement of the Petitioner, Hernstadt Broadcasting Corporation to be granted certain environmental permits from the Respondent, State of Florida, Department of Environmental Regulation, which would allow the Petitioner to construct a radio transmitter tower and access dock within the Biscayne Bay which is located in Dade County Florida. 1/
Findings Of Fact The Petitioner in this action, Hernstadt Broadcasting Corporation, owns and operates radio station WKAT, which is located in Miami Beach, Dade County, Florida. The Petitioner is licensed by the Federal Communications Commission to pursue this enterprise. On April 30, 1980, the State of Florida, Department of Environmental Regulation received an application from the Petitioner, which application requested permission to construct a radio transmitter tower and access dock in Biscayne Bay, Dade County, Florida. (The tower end dock are part of a proposed station complex in which the radio station building is to be constructed upland from the Bay.) The project, if allowed, would be located off the north side of the Julia Tuttle Causeway which connects the City of Miami and the City of Miami Beach via the Biscayne Bay. The tower and access dock, if constructed, would be located in submerged lands owned by the State of Florida. In view of the location of this apparatus in Biscayne Bay, it would be subject to the provisions of the Biscayne Bay Aquatic Preserve Act found in Chapter 258, Florida Statutes, together with other provisions of statute and rule. To place the access dock in the Bay, the Petitioner proposes to drive pilings into the Bay bottom to support the access dock which is 200 feet long and four (4) feet wide. The support mechanism for the radio tower would also be constructed by the driving of pilings into the Bay bottom and the radio transmitting tower, once built, would be 400 feet tall and would have attached stabilizing guy wires connected to anchors driven into the Bay bottom. As the pilings are driven into the floor of the Bay, the displaced soils will be compressed into lower elevations or redistributed against the pilings. Respondent's Exhibit No. 15, admitted into evidence, is a copy of the original application for permit, which was modified by site plans and sketches depicted in Respondent's Exhibit No. 16, admitted into evidence, shortening certain dimensions related to the access dock. (These modifications came about subsequent to the Department of Environmental Regulation's permit application appraisal found as Petitioner's Exhibit No. 10, which is dated June 23, 1980.) After review of the project, in the face of the aforementioned modifications, the Department of Environmental Regulation issued a letter of intent to deny the permit request. This letter of intent was dated September 9, 1980, a copy of which may be found as petitioner's Exhibit No. 11, admitted into evidence. The authority stated for such denial are these provisions of Subsection 258.165(3)(b), Florida Statutes (Supp. 1980), and Rule 17-4.242(1), Florida Administrative Code. Subsequent to the issuance of the letter of intent to deny, a further modification was made on the project increasing the length of the proposed access dock to the presently requested 200 feet. This modification is depicted in petitioner's Exhibit No. 12, admitted into evidence, which shows site plans and other pertinent information related to the project. Another modification to the project which the Petitioner claims is not subject to permit review by the Department of Environmental Regulation, and for which the Department of Environmental Regulation takes a contrary point of view, concerns the use of a grid of nickel-plated copper straps, approximately 40 feet by 40 feet, constituted of a mesh of approximately 1/4 inch in diameter by 1 inch sections to be placed underneath the tower and on the Bay bottom for purposes of grounding the tower. This item was not made known to the Respondent until September 30, 1980, at a time subsequent to the letter of intent to deny. The Petitioner in this action pursues the project on the basis of a joint use agreement entered into with the State of Florida, Department of Transportation, in which the Department of Transportation, in return for the ability to use the radio tower for communications in connection with a surveillance and traffic control system for Interstate Highway-95 and for the ability of the City of Miami, Florida, to use the facility for a tactical communication repeater installation, would grant to the Petitioner the Department of Transportation's rights and opportunities as easement holder in the area where the subject project would be constructed. See Petitioners' Exhibit No. 3, admitted into evidence. The Department of Transportation's rights stem from an easement grant from the Trustees of the Internal Improvement Trust Fund. See Petitioner's Exhibit No. 13, admitted into evidence. The rights of the Petitioner, by assignment from the Department of Transportation, do not relieve Petitioner of the obligation to gain the necessary approval of the Trustees of the Internal Improvement Trust Fund in the person of the State of Florida, Department of Natural Resources for permission to use those submerged lands over which the access walkway and tower would be constructed, notwithstanding any rights and privileges assigned to the Petitioner by the Department of Transportation as easement from the Trustees of the Internal Improvement Trust Fund. This is true because the perpetual easement granted from the Trustees to the Department of Transportation for right-of-way and dredging purposes related to the roadway which is constituted of the Julia Tuttle Causeway and to the adjacent Bay bottoms related to construction and maintenance of that roadway, does not envision assignment of the submerged lands to an entity in the position of the Petitioner, which entity does not have as its purpose the construction or maintenance of the roadway; hence, the necessity to gain permission from the Department of Natural Resources if the access dock and tower are to be constructed on the submerged land of the State. The easement held by the Department of Transportation is specific in nature and does not contemplate the construction of a radio station. (It is not necessary to comment on the question of whether a joint use agreement between the Department of Transportation and Hernstadt as that Department's assignee for rights and privileges bestowed upon the Department from the Trustees based on the easement rights granted on October 2, 1941, would allow the construction of the building of the radio station building which would be at the upland terminus of the access dock which also adjoins the radio tower, the Department of Environmental Regulation having offered no claim for permitting jurisdiction over the radio station building.) The Petitioner proposes to move its radio station from the existing location in Miami Beach because buildings in the general area of the radio station interfere with the radio signal and, in addition, there is interference caused by radio transmissions from Cuba. The terms of the license held by Petitioner on issuance from the Federal Communications Commission limit the movement of the station's transmitter tower to a location no more than four (4) miles from the current location. At the time of the hearing, the Petitioner had not located an alternative tower site, other than the proposed site. As stated before, if the tower were constructed, the State of Florida, Department of Transportation would utilize the tower in its communications network and the City of Miami Fire and Police Departments would likewise desire to use the tower. The Florida Marine Patrol and the Florida Highway Patrol would also be interested in using the proposed tower for communications purposes. The City of Miami Planning and Advisory Board and the City Commission of that municipality would be in favor of the construction of the proposed radio tower. Dade County, Florida, has adopted a Comprehensive Master Plan, copies of which may be found as Respondent's Exhibit No. 19, admitted into evidence. Within that document is a discussion of environmental concerns within the county to include Biscayne Bay and, in particular, concern for protection of environmentally sensitive areas such as Biscayne Bay and an interest by the County to provide a wide range of public water oriented opportunities for the populace. Subsequent to the time of the submission of the permit application, and specifically, in October, 1980, Dade County, through its Metropolitan Planning Department and in conjunction with the Metropolitan Dade County Environmental Resources Management Department prepared a proposed Biscayne Bay Management Plan, a copy of which may be found as Respondent's Exhibit No. 17, admitted into evidence. This plan was approved by the Board of County Commissioners of Dade County, Florida, by an Ordinance, a copy of which may be found as the Respondent's Exhibit No. 18, admitted into evidence. The Biscayne Bay Management Plan encourages the enhancement of public access to the Bay for uses such as fishing, boating, shoreline wading and view in and the preservation and enhancement of the environmental, chemical and aesthetic qualities of the Bay. Furthermore, if the necessary permission could be obtained, Dade County, has future plans to use the subject Julia Tuttle Causeway as a public access to the Bay. The location of the radio tower and associated facilities would interfere with the proposed use by Dade County. The Department of Environmental Regulation, in keeping with Section 403.0615, Florida Statutes, 2/ through a program in conjunction with Dade County is attempting the restoration of the biological and chemical characteristics of the Biscayne Bay. Some of the items included in this program would be enhancement of aquatic vegetation, including seagrasses and mangroves and the promotion of aesthetics and public access to Biscayne Bay, to include the area of the Julia Tuttle Causeway. Radio station WKAT presents public service programs; is a part of the Emergency Broadcasting System and broadcasts emergency information in times of natural disaster. On the question of environmental implications of this project, the placement of the pilings would cause the destruction of certain seagrasses in that area, while at the same time promoting the introduction of marine life along the surfaces of the tower and dock supports. Seagrasses in the area where the grounding system would be placed may be destroyed and although the copper to be used would be nickel plated, thereby inhibiting the release of the toxic properties of the coated copper, eventually the nickel plating would break down and the marine life communities adjacent to the mesh would be harmed by the copper. The loss of seagrasses under the grid could cause a reduction in fish population. The installation of the radio tower and access dock in the Biscayne Bay is an impediment to navigation; however, the Petitioner intends to place channel markers to divert boat traffic away from the tower and its environs. There is no expected difficulty with run-off, discharges or other forms of pollution related to the construction or operation of the tower facility, although there will be some turbidity caused in the construction phases of the project. The project would be located in a State Aquatic Preserve within the meaning of Chapter 258, Florida Statutes; would be located in waters of the State within the meaning of Chapters 253 and 403, Florida Statutes; would be in navigable water within the meaning of Chapter 253, Florida Statutes, end would be in an Outstanding Florida Water within the meaning of Rule 17-4.242(1), Florida Administrative Code.
The Issue The issues to be resolved in this proceeding are whether the Department should issue a permit to Casetta, and whether the Department should issue a permit to Harbor Point. The two application proceedings were consolidated for hearing purposes. In many respects, common factual and legal issues relate to the two proceedings. For that reason, in the interest of economy of time and space, a single recommended order is being issued with respect to the two proceedings.
Findings Of Fact History of Proceedings In 1974, a prior owner of the property now owned by Casetta filed an application with the Department to entirely fill the pond which is the subject of this proceeding. A final order denying the application was entered by the Department on August 31, 1977. A second application to fill the entire pond was filed with the Department by Casetta's predecessor in 1979. During the pendency of that proceeding, Casetta purchased the property and by stipulation was permitted to be substituted as the Petitioner. The Department gave notice of its intent to deny the second application in February, 1981. Casetta challenged the Department's assertion that it had jurisdiction under the provisions of Chapter 253, Florida Statutes. The matter was forwarded to the Division of Administrative Hearings and given Case No. 81-1082. The matter before the Division has been closed, but it remains as a pending proceeding before the Department. It is being held in abeyance pending the resolution of Casetta's present application. The application involved in this proceeding was submitted to the Department during December, 1981. The City of Riviera Beach, Florida, granted local approval for this application; and on May 18, 1982, the Department issued a Notice of Intent to issue the permit. The Department published a notice of its proposed action in the Commercial Record, a Palm Beach County newspaper. The Florida Wildlife Federation and the Property Owners' Association of Singer Island together filed a request for formal hearing with the Department. The Singer Island Civic Association filed a separate request. Counsel for the Wildlife Federation and the Property Owners' Association withdrew during the course of the proceeding. It was indicated that these parties would voluntarily dismiss the requests for hearing, but no such papers were filed. No one appeared on behalf of the Florida Wildlife Federation or the Property Owners' Association of Singer Island during prehearing conferences that were conducted in this matter or at the final hearing. The Executive Director of the Florida Wildlife Federation testified as a public witness at the hearing and indicated that they were not participating in the proceeding as a party. During the pendency of proceedings respecting the Casetta application before the Division of Administrative Hearings, Harbor Point filed an application with the Department to install a culvert which would connect the pond that is the subject of the Casetta application with a pond located on property owned by Harbor Point through a culvert system. Harbor Point sought to have its application considered by the Department as an alternative to the Casetta application. On or about August 2, 1982, the Department issued a Notice of Intent to deny the Harbor Point application Harbor Point thereafter petitioned for a formal hearing. On or about June 4, 1982, the United States Corps of Engineers issued a permit to Harbor Point to construct its proposed culvert system. Description of Property in the Area of Proposed Projects. Casetta is the owner of approximately five acres of land that lie between the Atlantic Ocean and Lake Worth on Singer Island in Palm Beach County, Florida. The property includes a rectangular pond that is approximately three acres in area. This pond will hereafter be referred to as the "Casetta pond." Submerged lands in the Casetta pond were conveyed into private ownership by the Trustees of the Internal Improvement Trust Fund, State of Florida, in 1924. Harbor Point owns land adjacent to Casetta's property to the north. Harbor Point's property includes a pond which is configured in the approximate shape of an hourglass and is approximately one acre in area. A condominium apartment building has been constructed on Harbor Point's property. Harbor Point members own residential units in this facility. The area presently owned by Casetta and Harbor Point was, in its natural condition, a part of the littoral zone, a shallow, submerged area, on the eastern edge of the lake. Lake Worth is an estuarine water body located between the mainland and Singer Island. The littoral zone of such a lake is of fundamental ecological importance. It serves as a habitat for a wide variety of wildlife and serves to maintain water quality in the lake through uptake of nutrients by vegetation that thrives in the area. The natural condition of the area was markedly changed by the construction of State Road A-1-A. The highway separated the area, including what is now the Casetta and Harbor Point properties, to a large extent from the waters of Lake Worth. A culvert was constructed under the highway in the area of what is now the Harbor Point property. This culvert allowed tidal waters from Lake Worth to enter the area, and the area thus remained in a diminished fashion as a littoral zone of Lake Worth. Sometime between 1953 and 1964, landowners in the area constructed dikes which appear to have served as driveways along their northern and southern boundaries. Fill was placed on the Harbor Point property so that a pond was created in its present approximate configuration. The Harbor Point condominium facilities are presently in part set on the filled land. The Harbor Point pond remained connected with the waters of Lake Worth through the culvert system. The Harbor Point pond thus remains subject to tidal influences from Lake Worth. It is an estuarine system which serves as a part of the littoral zone of Lake Worth. The driveway to the condominium, however, completely Separated the Casetta pond from direct interaction with the waters of Lake Worthy. The Casetta pond is presently in an approximately rectangular configuration. Probably as a result of groundwater interaction, it is affected in a minimal manner by tidal influences in Lake Worth. The Casetta pond receives water from runoff and from groundwater interaction. It has become a freshwater body. While the Casetta pond is no longer a direct part of the Lake Worth estuarine system, and while it is by no means in its natural condition, it remains a wetland ecosystem. The pond is surrounded by mangrove communities. There is considerable biologic activity. Many bird species roost in the mangroves and feed in the pond. The mangroves provide shelter for aquatic organisms which are a food source for the birds. The pond does not support a wide diversity of marine plants or animals. A single species of minnow, mosquito fish, exists in substantial quantities These serve as a food source for birds including ducks, herons, egrets, and kingfishers It appears that the Casetta pond has been used in the past as a borrow pit to obtain fill for adjoining properties trenches, which are as much as six feet in depth, have been dug along the northern, southern, and eastern perimeters and across the pond. Because it is cut off from Lake Worth, and because of the ditches that have been cut through it, the Casetta pond is in a very deteriorated condition. While healthy mangroves surround the pond, they are, except to the west, extremely narrow populations due to the sharp banks that have been caused by dredging activity. The mangroves have no room to expand their population and are stressed due to invasion of upland vegetation such as Brazilian pepper. Widgeon grass exists in the lake bottom. Algae, however, has become the dominant vegetation in the pond. From 80 to 90 percent of the pond's bottom is covered by a mat of algae that ranges up to five and one-half inches in thickness. The algae population is increasing rapidly. Widgeon grass populations are being choked off by the algae. Dissolved oxygen levels in the Casetta pond are consistently low, below standards set in the rules of the Department. The oxygen demand of the algae community has depleted dissolved oxygen levels. While the Casetta pond functions as a wetland community, its values are severely reduced, and it appears that water quality in the pond is likely to continue to deteriorate. While by no means in a natural condition, the Harbor Point pond continues to function as a viable part of Lake Worth. This is a result of the pond being connected to the lake through the culvert system. The edges of the pond are populated by mangrove and cord grass communities. Marine species such as mullet are easily observable. Wading birds roost in surrounding vegetation and feed in the pond. The Harbor Point pond is basically a shallow, tidal water body. Water quality in the Harbor Point pond basically mirrors water quality in areas of Lake Worth to the west of Highway A-1-A. The Harbor Point pond has an eastern and western lobe connected by a narrower area, forming an approximate hourglass configuration. The eastern lobe is farthest from the connection to Lake Worth. Water quality in the eastern lobe is generally poorer than water quality in the western lobe and in Lake Worth. The deepest portion of the Harbor Point pond is in the eastern lobe. Wind action cannot serve to fully flush the waters of this area because of its relative isolation from the western lobe. Runoff from the Harbor Point condominium to the east of the pond and from a fire station parking lot to the west enters directly into the Harbor Point pond. It is filtered only by the action of grasses over which it flows. There is no ex-filtration drainage system. The culvert which connects the Harbor Point pond with Lake Worth runs from the western lobe of the pond under Highway A-1-A into Lake Worth. Lake Worth is a Class III water body under the Department's rules. The Parties' Proposals 1. The Casetta Application Casetta is proposing to construct a high-rise condominium on the eastern portion of its property. There is insufficient land on the property as it is presently configured to accommodate needed parking spaces. Casetta proposes to fill in 1.8 acres, or approximately 60 percent of the Casetta pond in order to construct parking facilities. Casetta has proposed to construct a culvert system that would connect the remaining portion of the pond with Lake Worth. The remaining portion of the pond would be regraded and configured. The northern and western boundaries would remain basically in their present configuration The remainder of the pond would be completely modified. A meandering shoreline would be created for an "L"- shaped pond. The bottom would be recontoured so that broader, shallow areas along the shoreline would be created. With the culvert system installed, the reconfigured pond would receive tidal waters from Lake Worth. The pond would effectively become, as the entire area once was, a portion of the littoral zone of Lake Worth. With the meandering shoreline and a gradually sloping bottom, the reconfigured pond would have as much area for littoral zone vegetation to establish itself as the present pond. Casetta proposes to commence construction activities by filling in a portion of the pond and regrading the remainder. The pond would be drained so that the algae that presently exists in large quantities would die and be removed. Clear fill material would be used to grade the pond. An exfiltration system would be created so that runoff that would reach the pond from upland areas would be filtered before it could enter the pond, thus reducing the impact of pollutants from upland runoff. The proposed culvert system would be in three sections. There would be a 35-foot section leading from the pond and slanting gradually downward to a point approximately eight to nine feet under Highway A- 1-A. The second section would be 110 feet long, lying vertically under Highway A-1-A. The third section would be 95 feet long, gradually rising from the second section to the bottom of Lake Worth. The bottoms of the open ends of the culvert in the Casetta pond and in Lake Worth would be at the ordinary low-tide marks. The top would be below the ordinary high-tide marks. Thus, the culvert openings would be exposed at low tide and submerged at high tide. The portion of the culvert under A-1-A would be filled with water at all times. It is necessary to place the culvert at least eight feet under Highway A-1-A in order to avoid utility pipes and cables that lie under the highway. The portion of the pipe under A-1-A would be installed through a boring technique known as "jack and bore." This technique would obviate any need for the closing of traffic on Highway A-1-A. The portion of the culvert in the Casetta pond and in Lake Worth would be installed by digging trenches, laying the pipe, then filling the trenches. Two openings would be made in the pipe at either end of the deep sections. These would be "manhole-type openings that would allow for periodic maintenance. Installation of the portion of the pipe in Lake Worth would be accomplished by building a work platform into the lake from material that is dredged from the trench. Once the pipe is laid, the material from the work platform would be placed back on top of the culvert, and any extra material would be removed from the site. Turbidity screens would be used to surround the project to reduce the short-term impacts of turbidity caused by construction. Once the pond is reconfigured and the culvert is installed, tidal flows would be introduced to the reconfigured pond on a gradual basis in order to observe any problems that might result. Shoreline grasses such as cord grass would be introduced in the shallow areas, and mangroves removed during filling operations would be replanted along the shoreline. This would serve to stabilize the shoreline and to provide the beneficial effects of littoral zone vegetation, including wildlife habitat and water quality benefits. The reconfigured Casetta pond would be approximately 33,000 square feet in area. If the culvert system functions as proposed, the reconfigured pond would become a part of Lake Worth. There are environmental and ecological advantages and disadvantages to the proposal. The disadvantages are rather obvious. One and eight-tenths acres of wetland habitat would be eliminated. While the present Casetta pond is only a marginally valuable wetland, it is not without its beneficent effects as have been described above. Furthermore, during construction, the habitat values of the Casetta pond would be lost, and short-term deleterious water quality impacts would occur in Lake Worth. There are trade-offs. The proposed filling, regrading, and connecting of the ponds to Lake Worth could have substantial positive impacts. The most apparent of these is that Lake Worth would regain 33,000 square feet of littoral zone. Construction activities have removed as much as 75 percent of the Shoreline vegetation that once Surrounded Lake Worth. The littoral zone has been replaced with developments that in ecological terms have negative impacts. Reconnecting the ponds to Lake Worth would be a slight reversal of that trend. Habitat for marine species would be increased, and the "kidney effect" that shoreline vegetation provides would be reestablished. Except during construction, Casetta's proposal would have no adverse water quality impacts upon surrounding waters. Adverse impacts during construction would be minimized by protective techniques that Casetta has proposed, including the use of turbidity screens. Long-term water quality impacts of the proposed project would be positive. Water in the present Casetta pond is of poor quality. The pond does not presently serve any water quality function for Lake Worth, since it is not connected to Lake Worth. Connecting the reconfigured pond to Lake Worth would allow waters from the lake to be purified through nutrient uptake by littoral zone vegetation. In habitat terms, the filling would reduce the total area of wetland habitat. The quality of the habitat would, however, be vastly improved. Rather than an unnatural, stagnant pond which provides habitat for only a few varieties of very common freshwater minnows, a marine habitat would be provided for all manner of creatures that survive in the littoral zone of estuarine water bodies. Bird habitats would not be reduced, since the shoreline of the lake would not be lessened. Thus, while the Casetta proposal would reduce the total size of wetland habitat, it would vastly improve it and would not have a detrimental effect that would be contrary to the public interest. In order for the reconfigured Casetta pond to offer an improved wetland habitat and a positive water quality impact for Lake Worth, it is essential that the proposed culvert system functions so as to allow an unimpeded interchange of water between the reconfigured pond and Lake Worth. If the culvert system does not operate, the result of the proposed project would be merely to lessen wetland habitat. Rather than a three-acre unnatural wetland habitat, there would be a 1.2-acre unnatural wetland habitat. Such an adverse impact upon wildlife habitat would be clearly contrary to the public interest. Furthermore, limited exchange of water between a eutrophic pond and Lake Worth could have an adverse impact upon water quality in Lake Worth so as to result in violations of the Department's water quality standards along the border of Lake Worth. The evidence does not establish that the proposed culvert system will properly function. Casetta had proposed a 36-inch culvert. Robert Snyder, a consulting engineer, was retained to determine the flushing characteristics of the culvert. Snyder calculated that maximum velocities associated with mean or average tides through the culvert system would be 1.89 cubic feet per second. Snyder calculated that this exchange rate would be sufficient to flush sediment and debris that would collect in the culvert. Thus, the culvert would be self- cleaning with only limited maintenance required to keep it open. In calculating the exchange rate, Snyder utilized the wrong formula. He overestimated the exchange rate by a factor of two. If the rate estimated by Snyder is reduced by a factor of two, it is apparent, that the exchange rate would not be sufficient to flush the culvert. Sediment and debris would collect in the pond, and rather regular maintenance would be required. Mechanical means can be utilized to clean a clogged culvert. A culvert of the length and configuration proposed by Casetta is difficult to clean through mechanical processes, however, and the processes themselves increase turbidity in the area. The evidence does not establish that regular maintenance would be sufficient to keep the culvert free of sediment and debris so that there would be a free exchange of water between Lake Worth and the reconfigured pond. When engineer Snyder was made aware of his miscalculations, he proposed reducing the size of the culvert to 24 inches. He testified that this would adequately increase the exchange rate so that the culvert would be selfmaintaining. Snyder's testimony in this regard has not been deemed credible. Given the witness's use of an erroneous formula in calculating exchange rates and another error that he admitted making in calculating scour potential, the witness cannot be considered competent to give expert testimony in these areas. If the culvert system proposed by Casetta allowed for the free exchange of waters between Lake Worth and the reconfigured Casetta pond, the water quality and habitat impacts of the proposed Casetta project would be, on balance, positive. The evidence does not, however, establish that the culvert system would function. It appears likely that the culvert system as proposed would be frequently clogged with sediment and debris, thus preventing the exchange of waters between the reconfigured pond and Lake Worth. The result of the proposed project would therefore be a reduction of wildlife habitat with potentially adverse water quality impacts upon the waters of Lake Worth. 2. The Harbor Point Proposal Harbor Point has proposed to install a culvert system that would connect the Casetta pond in its present configuration with the Harbor Point pond. Since the Harbor Point pond is connected through a culvert system with Lake Worth, the Harbor Point proposal would result in opening the Casetta pond to tidal influences from Lake Worth. Harbor Point has presented no evidence as to construction techniques that would be utilized and has provided no assurance that the construction itself would not result in water quality violations in the Harbor Point pond and in Lake Worth. Opening the Casetta pond in its present configuration to tidal influences would have the positive impact of allowing an exchange of water from the Casetta pond. Water quality in the Casetta pond would inevitably be improved. Given the configuration of the bottom of the Casetta pond, with its deep troughs, a complete exchange of waters would not occur, and water quality in the Casetta pond would be likely to remain poor, albeit improved. The Harbor Point proposal would have short-term and long-term negative impacts upon water quality in the Harbor Point pond and in Lake Worth. Simply opening the Harbor Point pond and Lake Worth to exchange of poor-quality water with the Casetta pond would have a negative impact. As water quality in the Casetta pond improves, this impact will be lessened, but will remain. Furthermore, the proposed culvert would result in poorer flushing of the waters from the eastern extremity of the Harbor Point pond. This would occur as a result of increased water velocities in the western extremity. Water quality in the eastern extremity of the Harbor Point pond is already stressed, and reducing the flushing characteristics of the pond would be likely to result in violations of the Department's water quality standards in the eastern portion of the Harbor Point pond. While the Harbor Point proposal would have the ecologically positive impact of opening the Casetta pond to tidal flows, it would have the negative impacts of reducing water quality in the Harbor Point pond and potentially along the shoreline of Lake Worth. Water quality in the Casetta pond would thus be improved at the expense of water quality in the Harbor Point pond and in Lake Worth. Riparian Rights Harbor Point owns a narrow fringe of the northern border of the Casetta pond. The precise amount of the Casetta pond that is owned by Harbor Point cannot be determined from the evidence, but it is clear that Harbor Point owns some portion of the Casetta pond which may be at one point as much as six feet of the northern portion of the pond. The Casetta pond offers minimal amenity to Harbor Point. The pond is unsuitable for boating, bathing, swimming, or any commercial enterprise. The pond is largely blocked from view by Harbor Point residents by abundant mangrove and upland vegetation. Reconfiguration of the pond as proposed by Casetta would not change the northern boundary of the pond, and it would remain largely blocked from view by Harbor Point residents. To the extent that the Casetta pond provides a view for Harbor Point residents, it is only minimally attractive given the configuration of the pond and given the fact that a high-rise condominium has been constructed on property to the south of the pond. There is no evidence in the record from which it could be concluded that the value of Harbor Point property would be in any way reduced as a result of the projects proposed by Casetta.
Findings Of Fact Permitting History This development was originally known as North Largo Yacht Club and was owned and developed originally by the Largo Brand Corporation. That developer and this development received Development of Regional Impact approval from the county commission of Monroe County in accordance with Chapter 380, Florida Statutes in 1974. In 1975 that developer received various permits and water quality certifications authorizing construction of the "Atlantic Marina" (the existing marina) from both the Florida Board of Trustees of the Internal Improvement Trust Fund and the United States Army Corps of Engineers. The marina was ultimately constructed and no further governmental approvals are required for the present Respondents to make full use of the existing marina which has an authorized boat capacity of 363 boat slips, which are situated around long piers extending from the shore of the marina basin out into the marina basin. Sometime after construction of the marina, the mortgagee, through foreclosure, obtained title to the property from Largo Brand Corporation which has since dissolved, ultimately conveying it to City National Bank as trustee under a Florida land trust. City National Bank filed the present application in its original form but in February, 1984, conveyed the property to Port Bougainville, Inc. and Port Bougainville Enterprises, Inc., the present Applicant/Respondent who succeeded City National Bank as the real parties in interest prosecuting the present permit application, as modified. The permit application as it presently exists is the result of various modifications suggested by the Department of Environmental Regulation and agreed to by the present Applicant/Respondents, which had the effect of causing the Department to change its position from one of denial of the permit to one of approval, by issuance of a Notice of Intent to grant the permit in June of 1984. The Applicant/Respondent's original decision to apply for the new permit was based upon aesthetic considerations and a desire to redesign and change the theme of the development and the marina itself. It is thus proposed that the boat-mooring facilities be moved to the periphery of the basin and the piers or docks extending out into the basin be removed. This would create an open body of water in the basin, more in keeping with the "Mediterranean Village Harbor" theme of the entire development. The original application filed in early 1984, called for realignment of the docks rather than removal, and the creation of various baylets or inlets along the access canal and contained no proposal for shoaling the existing boat basin. The Department used this original proposal as a basis for its Intent to Deny the Permit Application since it considered those modifications unacceptable in terms of the likelihood that it might degrade water quality or at least not improve the ambient water quality then existing in the marina basin and entrance canal. The Respondents acceded to the demands of the Department, employed additional consultants and redesigned the project, including the creation of a sophisticated hydrographic model by which, and through which, the Respondents ultimately proposed (with the Department's agreement) to revise the application as follows: Shoal the entire basin and canal system to no more than -6 Ft. mean low water; widen and sculpt the access canal on the west side and install solid flow baffles on the east side so as to create a sinusoidal or curving configuration in the canal to improve mixing of the water in the canal and basin system; remove the existing docks and construct new docks around the periphery of the basin so as to provide a decreased number of boat slips and capacity for a total of 311 boats; install one bubble screen surrounding the fueling facilities to contain oil and fuel spills and another at the entrance of the access canal where it opens into the Garden Cove Channel so as to prevent organic materials from outside the canal and basin system from being carried into it with tidal currents and wind; installation of "batter boards" along the length of the waterward or easterly and southeasterly side of the access canal so as to protect the mangroves along that side of the canal from the effects of wake energy caused by boats. After further "free-form" review, investigation and negotiation, the Department required, and the Respondents agreed to make the following additional modifications to the marina development plan: Shoal the north end of the basin to -4 ft. mean low water; slightly reconfigure the access canal and install an additional wave baffle on the eastern periphery of the canal in order to improve circulation in the western portion of the boat basin; relocate the proposed fueling facilities more toward the rearward center of the basin in order to further isolate them from the outstanding Florida waters lying at the outward, "seaward" end of the project; provide funds necessary to more adequately mark the Garden Cove Channel in accordance with the requirements specified by the Department of Natural Resources so as to further ensure that boat traffic and possible propeller damage could be prevented to the marine grassbeds and other marine life on either side of the Garden Cove Channel; install tidal level gauges at the mouth of the Garden Cove Channel which would show boaters wishing to use the channel and access canal the current, minimum depths prevalent in the channel and canal; grant to the Department a "conservation easement" binding upon the Respondent which would provide the following: That no hydraulic connection be made from any of the upland lakes on the Respondent's property to the marina, to the canal, to the channel or any other state waters; an agreement not to employ boat lifts that would require a dredge and fill permit from the Department; an agreement not to apply for additional permits so as to increase the number of boat slips in the marina beyond the 311 presently proposed; to develop a reef management plan in conjunction with the Florida Audubon Society to include educational programs for the public as well as underwriting the installation of mooring buoys and adequate channel markers in the John Pennekamp Reef Park, the Outstanding Florida Waters (OFW) involved in this proceeding. During the time of construction of the proposed marina modifications, the entire marina will be closed and isolated from the waters of Garden Cove by the installation of a dam at the entrance to the marina access canal where it opens into Garden Cove. The dam will remain in place until turbidity resulting from the dredging, filling and construction has settled and the waters in the marina have achieved the turbidity standards required by the Department and its rules contained in Chapter 17 3, Florida Administrative Code. All the proposed modification work will be performed landward of the surveyed mean high water line. Additionally, a storm drainage system will be installed which will prevent any stormwater runoff from being deposited into the marina harbor. The stormwater runoff will be routed away from the harbor through the use of a reverse gradient around the periphery of the harbor and runoff from the adjacent real estate development will be thus routed away from the harbor into grass swales to be collected into holding areas for filtration. Ambient Water Quality in the Marina and Garden Cove Respondents tendered Dr. Earl Rich, a professor of Biology at the University of Miami as an expert in ecology and he was accepted without objection. Since 1974 he has conducted extensive studies with attendant sampling, observation and water quality monitoring in the Port Bougainville Marina. Beginning in 1983 he also performed certain chemical analyses on the water samples from the marina. Photographs taken underwater in the marina basin were adduced and placed in evidence, as were the results of the observations and tests. It was thus established that there is a dense growth of macroalgae in the marina at a depth of about six feet, although at the nine-foot level there is much less such growth. Concomitantly, the deeper holes in the marina basin exhibit a low dissolved oxygen reading and are largely responsible for the frequently occurring, low dissolved oxygen reading in the marina system that is lower than acceptable standards embodied in Chapter 17-3, Florida Administrative Code. Garden Cove itself is a shallow embayment open toward the Atlantic Ocean in a generally easterly direction, characterized by a rocky or coarse sediment bottom substrate. It is characteristic of this area that organic materials such as seaweeds and the like, are transported by currents and winds into Garden Cove from other marine areas. The underwater vegetation in Garden Cove is lush. There are extensive shallow-water marine grass beds. These vegetated areas support a large population of marine animals and fish. Dissolved oxygen is, of course, essential to the metabolism of these organisms. The two primary means for oxygen to enter the water are as a result of photosynthetic activity of marine plants and through oxygen entering the surface waters through waves and wind action, with that surface water being distributed and mixed so as to disburse the action throughout the water column. The term biochemical oxygen demand or BOD, refers to the rate at which organisms use oxygen in the water. If there are many active photosynthetic organisms, as in Garden Cove, the production of oxygen during the day, as for instance by the seagrasses in the cove, exceeds the BOD of the plant and animal community in the water body, in which case the plants contribute excess oxygen to the air. During hours of darkness, plant and animal communities in the water body will continue to consume oxygen although there will be no photosynthesis to contribute oxygen. Therefore, in an underwater community rich in plant and animal life, such as Garden Cove, the dissolved oxygen level is typically higher during the daylight hours and BOD readings will be decreased during the night, reaching a low level during the early morning hours. Frequently, dissolved oxygen readings in Garden Cove are below state standards for waters of the State under natural conditions. These low DO readings occur commonly in Garden Cove during conditions of calm wind. Indeed, Dr. Rich has measured dissolved oxygen in Garden Cove below the four-part per million state standard even before the present marina and canal were ever constructed. Since the opening of the marina there have been times when the DO readings in Garden Cove have been lower than those inside the marina itself. Hydrodynamics of the Modified Marina The proposal by the permit applicant calls for widening the access channel into the marina to approximately 130 feet by excavating upland on the western bank of the canal. The access canal will then be reconfigured during the excavation into a winding or curving fashion. That adjustment, along with the solid flow baffles to be installed on the eastern bank of the canal, will set up a winding or sinusoidal flow of tidal currents. The sinusoidal flow will induce secondary helical currents that will move water repeatedly from the top to the bottom of the canal and then back, thereby significantly improving the mixing action. The improved mixing of the waters in the canal and marina will serve two purposes: It will disperse any pollutants so as to reduce pollutant concentrations. It will disperse the oxygen introduced into the surface waters by wave and wind throughout the water column. Dr. Bent Christensen is Chairman of the University of Florida Hydraulics Lab. Using knowledge gained in hydrographic modeling as a result of work he performed in carrying out a "Sea Grant study" under the auspices of the University of Florida, Dr. Christensen designed a computer model of the proposed Port Bougainville marina and access canal by which, in turn, he designed the winding access canal which will emulate nature in producing a turnover of water induced by current velocities and canal configuration, rather than by temperature differences in water. The computer model takes into account tidal flows and wind-induced velocities which are important to mixing of water within the system. Using this model, Dr. Christensen was able to redesign the marina canal so as to improve water quality within that system as well as improving the quality of water leaving the system into Garden Cove. Drs. Lee and Van de Kreeke are ocean engineers who testified as expert witnesses on behalf of Petitioners. They sought to dispute Dr. Christensen's conclusion that the redesign would improve DO levels within the marina based upon their independent determination that a different design would increase flushing times for the system. Flushing, however, is a simplistic way of analyzing water quality. Flushing analysis assumes that the only means to improve water quality is to replace water within the system with water from outside the system. The Christensen model and the resulting proposed design of the marina and canal, on the other hand, improves water quality through internal mixing action. The proposed design actually reduces flushing time, but more importantly, maximizes dispersion of water within the system and along with it, dissolved oxygen. The design introduces dissolved oxygen throughout the water column in the system through internal mixing because of the sinusoidal configuration of the canal and the helical currents the canal configuration sets up. The concentration of pollutants measured by the State Water Quality Standards are, in turn, reduced through the same hydrodynamics. Dr. Van de Kreeke admitted that a key ingredient in his model was the assumption he had regarding BOD in the system, but he had no idea what the BOD extant in the Port Bougainville system might be. He also admitted that his calculations did not take into consideration the factor of wind mixing of the waters in the system and acknowledged that wind can and does play an important role in flushing and mixing the waters in marinas. Finally, Dr. Van de Kreeke admitted that he could not fully analyze Dr. Christensen's assumptions in arriving at his model and design because he did not have the information Dr. Christensen relied upon. Thus, Dr. Christensen's model and design is accepted as more credible than that of Drs. Van de Kreeke and Lee. That model and design establishes that the quality of water exiting the marina into the Outstanding Florida Waters in Garden Cove will be improved by the modifications proposed to be constructed in the marina. Impact on Benthic Communities The northerly end of the marina basin will be sloped from -6 feet to - 4 feet. This widening and shallowing of the marina basin and access channel will have the affect of promoting the growth, regrowth and welfare of the benthic communities in the waters in the marina and access canal by providing greater light penetration to the bottom of the marina. The widening will have the effect of causing a greater portion of the marina bottom to be lighted during the day since at the present time, the bank and surrounding trees shade the marina basin for substantial portions of the day. The increased light penetration will result in more photosynthetic activity by the plant life in the marina and canal such that increased amounts of oxygen will be produced enhancing the dissolved oxygen levels of the marina waters. In that connection, the Respondents' expert, Dr. Rich, has examined a number of marinas and observed very healthy benthic communities in marina harbors more densely populated with boats than will be the proposed marina. Another significant improvement in the ecological status of the present marina will be the placing of a bubble screen device across the mouth of the entrance canal. This will have the effect of preventing floating organic materials such as sargassum, from entering the marina. Marinas typically experience problems related to dissolved oxygen levels in their waters because of an accumulation of floating organic material which tends to settle to the bottom creating excessive biochemical oxygen demand in their decomposition process, thus resulting in decreased dissolved oxygen levels. Thus, the bubble screen will aide in decreasing BOD. Likewise, a bubble screen device is proposed to be placed around the fueling facilities in the rearward portion of the marina basin so as to prevent the spread of pollutants such as spilled oils, greases and fuels, which may occur during routine fueling operations from time to time. Inasmuch as the modifications have been shown to cause some improvement in the dissolved oxygen level in the waters of the marina basin and access canal, it has been demonstrated that the modifications will not interfere with the conservation of marine wildlife and other natural resources. The bodies of water consisting of the marina, the access canal and Garden Cove, at the present time support a diverse marine community that can be expected to continue to flourish. Neither will the proposed activity destroy any oyster or clam beds, as none have been shown to exist in these waters. Dr. Rich has monitored waterways and offshore waters at a nearby, comparable marina, The Ocean Reef Club, for approximately ten years. He has discerned no noticeable impact on the benthic communities within that marina from a very heavy boat traffic during that period of time. The boats using The Ocean Reef Club Marina are typically larger than will use the Port Bougainville facility and boats of over 100 feet in length commonly use The Ocean Reef Club. In terms of impact on offshore benthic communities, he has observed no visible impact by the heavy amount of boat traffic using The Ocean Reef Marina from the standpoint of comparison of the experience with that marina, in terms of biological impacts, with the marina configuration proposed by the Applicant/Respondents. In short, the proposed marina configuration as contrasted to the existing permitted marina, represents an improvement because of the increased surface area providing increased oxygen exchange through wave and wind action, the shoaling which will also be beneficial to dissolved oxygen levels because of its enhancement of photosynthetic processes, and because of the proposed marina management steps designed to prevent floating organic material from entering the marina. Thus, the modified design was shown to provide a meaningful improvement in general ecological conditions within the marina and hence, in the offshore waters of Garden Cove with which the marina waters exchange and mix. Water Quality Dr. Eugene Corcoran is Professor Emeritus of the Rosensteel School of Marine and Atmospheric Sciences. He is a marine chemist and performed a chemical analyses of the samples taken for the water quality report presented by Respondents and in evidence as Respondent's Exhibit 17. Dr. Corcoran also performed the analyses for the ongoing water sampling program conducted by Dr. Renate Skinner, an expert witness for Petitioners. The Petitioners accepted Dr. Corcoran as an expert witness without objection. The proposed marina modifications involved in this permitting application were thus shown to cause no violations of the state standards for dissolved oxygen. The Rio Palenque Water Quality Study in evidence indeed documented a number of instances where dissolved oxygen fell below the state minimum standards of four parts per million in the present marina. Once the modifications are completed there still may be instances when dissolved oxygen falls below that standard, but this can be attributed to natural phenomenon and the same relatively low levels of dissolved oxygen below state standards have been observed in the offshore waters of Garden Cove itself, which is an Outstanding Florida Water. Significantly, however, it was established that concentrations of dissolved oxygen will likely increase as a result of these modifications, the inducement of the helical flow and consequent vertical mixing, the widening of the entrance canal and the shoaling of the bottoms in the marina basin and canal, as well as the measures to be taken to reduce the deposition of organic materials in the marina basin and canal. The only water quality criteria placed in contention by the Petitioners and Intervenors were dissolved oxygen and copper. Although a number of Petitioners' witnesses were qualified to address the impacts of water quality on different marine organisms, only Dr. Curry was qualified as an expert in water quality. Dr. Curry's chief concern was with dissolved oxygen, which is based on the Rio Palenque Study showing present low values for dissolved oxygen in the marina as it now exists. Dr. Curry did not establish that the proposed modifications to the marina would themselves cause dissolved oxygen violations and although he testified in great detail concerning his attempt to compute the amount of copper that might be given off by the bottom paint of boats in the modified marina, he was unable to render an opinion that the modifications would increase copper levels in the waters in the marina. He acknowledged that his calculations were based on the assumption that all the boats in the marina would be using copper anti-fouling paints and his calculations took into account an assumption that all boats in the marina would have been painted within the last six months as a base datum for his calculations. Additionally, he did not take into account dispersion ratio associated with the hydrodynamic forces present in the modified marina. Dr. Curry admitted that he had never studied copper levels in a marina environment and was unable to explain the chemical effects on water quality of copper anti-fouling paints on boats. In all his sampling, he only found one instance of a violation of the Chapter 17-3 copper standard and that occurred within only a few millimeters of the hull of a newly-painted boat. Other fallacies involved in Dr. Curry's analysis, concern the interaction of seawater with copper bottom paint. Since seawater has a high level of carbonates, copper is immediately complexed with organic compounds such as amino acids. These organic complexes are soluble in seawater and indeed, serve as important nutrients to phytoplankton and other beneficial marine organisms. Thus, that portion of the total complex copper precipitated from the water as well as that portion taken up as nutrients would not be included in any concentrations of copper measured in the water column. Additionally, Dr. Curry's computations did not take into account the dispersion of copper concentrations due to mixing or flushing, which has a direct beneficial effect on reducing concentration of copper and other pollutants in the water column. Thus, Dr. Curry's computations are deemed immaterial, inasmuch as he effectively admits that the modifications to the marina would not be detrimental to water quality. The proposed modifications will not lower ambient water quality or significantly degrade the waters in the adjacent John Pennekamp Park, Outstanding Florida Waters. Since it has been established that the marina modifications will likely improve water quality within the marina, logically, the water quality in the park to some degree might be slightly improved, since those waters exchange with the waters in the marina. There will be no increase in concentrations of any pollutants emanating from the Port Bougainville Marina as a result of the proposed modifications. Improved Marking of Garden Cove Channel The Applicant/Respondents are required to provide improved navigational markers in the Garden Cove Channel, pursuant to an amended development order. Additionally, they have agreed to provide additional channel markers delineating the channel from the entrance of the existing marina to the Garden Cove Channel proper. With regard to the Garden Cove Channel, the Respondents proposed to move certain existing channel markers to more clearly identify that channel, which would make certain portions narrower and thereby eliminate boat passage over some shallow areas populated with marine grasses which presently lie within the marked channel. The Respondents also propose to add two more sets of channel markers at the seaward end of Garden Cove Channel, so that boats exiting the channel heading for the open sea will avoid certain shallow marine grass areas. The reason for this is to avoid possible damage to valuable marine grass beds and habitat which might be caused by prop wash of boats crossing over them, as well as actual contact and scouring by propellers or potential grounding of boats navigating these areas. Witness Balfe for the Respondents has personally sounded the entire length of the access canal and Garden Cove Channel. His soundings are admitted in evidence as Respondent's Exhibit 19 and are unrefuted. It was established therefore, that the bottom configuration of that access channel is basically flat or level with only minor irregularities of less than a foot. There are no rock outcroppings or other obstructions which would reduce the controlling depth below -4 feet. Approximately 12 times per year however, during "spring tides", the ambient water depths in Garden Cove could be expected to go below -4 feet mean low water. During these times the tide will be approximately 6 to 8 inches below that normal depth. Perhaps 25 times per year the tide is 5 or 6 inches below that mean low depth. The tide gauge which will be installed will alleviate possible propeller scouring or grounding damage to grass beds and marine habitat, especially during those abnormally low tides, by providing boat operators a current, up-to-date reading on the depths in the channel. Contributions to Park Management Plan and Marina Management Plan The Applicant/Respondents have agreed to a permit condition requiring a financial commitment to assist in the management of the John Pennekamp Park so as to minimize the adverse impacts of human use of the park. This commitment includes the provision of $75,000 to finance a study and preparation of a management plan for the John Pennekamp Coral Reef State Park and Key Largo National Marine Sanctuary, which would include study of the feasibility of inaugurating an entry permit system for the park, a testing and certification program for commercial dive boat operators, possible zoning of the park to allow recovery of the park coral reefs and other resources from the impacts of human visitors, locating central mooring buoys so that visitors' boats could be moored in one restricted area to avoid damage to the delicate coral reefs, and more adequately marking the boundaries of the park. Additionally, the Respondents propose to provide $50,000 for the acquisition of anchor buoys to be placed in selected areas of the park and to provide funds to finance a survey to more adequately identify the boundaries of the park. In order to more adequately protect water quality in the marina itself, the Respondents will inaugurate a marina management program which will include the installation of a sewage pump-out station and a pump-out station for motor oils and lubricants for boats. In addition to the two bubble curtains mentioned above, the Respondents will install containment booms and absorption mats and will permanently maintain a boat equipped with absorption mats and suction equipment for fuel or oil spill removal. The marina will prohibit persons living aboard boats, to prevent attendant sewage effluent problems, and will prohibit maintenance of boats, including painting and oil changes, while boats are in the water. This program will be monitored by an environmental protection officer employed by the condominium association under the auspices of the Respondents. Many of these marina management provisions are already requirements of the Port Bougainville 1982 development order referenced above. Management of Inland Lakes Although the use and management of the inland lakes on the Respondents' property is not directly involved in this permit application proceeding, the Respondents' overall development plan encompassed by the development order anticipates that at a future time a boat lift will be installed on upland so as to allow boats to be transferred from the inland lakes into the marina for access to marine waters. The lakes themselves, however, will not be open to the marina or to outside waters. The inland lakes are anticipated to provide dockage for approximately 200 boats, with restrictions against boats exceeding 20 feet in length and boats powered by combustion engines. The Respondents expect that the inland lakes will be primarily used by small boats such as canoes or sailboats. Dry storage for boats will be maintained on an upland site, for which a DER permit is not required. Neither is a permit for a boat transfer facility required since it would not involve dredging, filling or construction over water. The use of a boat lift, although it itself is not an issue before the Hearing Officer in this proceeding, would involve the potential of 200 or more boats using the marina in addition to those for which the marina is designed. This could occasion substantially greater risk for oil, grease and fuel spills and other potential damage to the water quality within the marina and damage to the marine habitat, grass beds and so forth within the marina, the access canal and the adjacent areas in Garden Cove. Accordingly, the conservation easement which the Respondents have agreed to provide the department as a condition to the grant of this permit should be amended to add a further condition on a grant of this permit so as to preclude placement of boats from the inland lakes into this marina or its access canal. Such a restriction would comport with the proposed uses of the inland lakes established by Mr. Scharenberg, the Respondent's principal. Boating Impacts Boat traffic in the Garden Cove Channel area is significant, with heaviest traffic occurring on the weekends when approximately two to three hundred boats navigate that channel. The boats presently using Garden Cove Channel come from a number of nearby marinas, small fishing docks and dry storage areas, as well as from a marked navigational channel called North Creek that provides access to the Garden Cove area and the Atlantic Ocean from Largo Sound. A small canal cuts through Key Largo into Largo Sound and provides access for boats in the Black Water Sound and other areas on the west side of Key Largo to the Garden Cove area and the Atlantic. The Port Bougainville Marina is expected to attract a mix of boats typical for such a marina, with the majority consisting of boats ranging from 27 to 35 feet in length. Approximately 20 percent of the boats will likely be in the 40-foot range. Larger boats may also use the marina, particularly those with a shallow draft, and "shoal draft" sailboats of 35 to 40 feet can safely navigate in and out of the marina. The marina, as it would be modified, would permit use of boats with a draft of up to three and one-half feet, although deeper draft boats could use the marina by timing arrivals and departures for the high tide, which is a common mode of operation by boat operators in the Florida Keys and other marine areas. The Port Bougainville Marina will contribute approximately 30 to 50 boats to the Garden Cove boat traffic on an average weekend out of the possible 311 boats in the harbor as it is proposed to be constructed. There will be a lesser number of boat arrivals and departures during the weekdays. The primary users of boats in and out of the marina will be people who own condominiums in the attendant real estate development. Temporary visitors, not owning boats moored in the marina, would typically use the dive charter boats and other rental boats in the surrounding areas, such as at the Ocean Reef facility. The existing marina which is already permitted and can be fully used at the present time from a legal standpoint, could accommodate the same reduced number and sizes of boats as the proposed modified marina by simply removing some of the present docks and finger piers. The Respondents propose to maintain approximately 20 slips for boats which are not owned by condominium unit owners, and they anticipate operating six to seven deep-sea charter boats as well as five smaller skiff-type charter boats, and perhaps as many as two dive charter boats with additional demands for charters to be serviced by charter boats in the surrounding areas. Boating adverse impacts on the marine benthic communities inside and outside of the marina will be minimized by the construction configuration of the marina and boat slips, the shoaling and widening of the marina basin and canal, and the channel marking and tidal gauging provisions proposed by the Applicant/Respondents. These safety arrangements would be further enhanced by the above-mentioned restriction on the placing of boats into the waters of the marina and canal from the inland lakes. The configuration of the proposed modified marina and the shoaling will have a beneficial effect in rendering use by extremely large boats, which might cause propeller, wake or grounding damage to the marine benthic communities unlikely because of the inaccessibility caused by the intentional shoaling. Coral Reef Impacts Dr. Peter Glynn is a qualified expert in marine ecology and was accepted as an expert witness in that area with particular emphasis, through his long specialization, in the ecology of corals and coral reefs. He has researched the effects of sediments, herbicides, pesticides, oxygen levels, temperature, salinity, tidal effects and oil pollution on corals. He testified as a rebuttal witness addressing concerns raised by Petitioners' and Intervenor's witnesses with regard to boat traffic, attendant turbidity and possible synergistic effects on coral reefs caused by oils, greases, low oxygen levels and turbidity. Dr. Glynn has studied corals in many areas of the world including the Caribbean and the Florida Keys. The coral reefs in Florida are similar to those in the Caribbean area and belong to the same "biogeographic province." He has dived in and examined the Garden Cove area and found four species of small reef building corals in Garden Cove. These were found in the vicinity of a shipwreck near the channel entrance to Garden Cove and the remainder of the corals observed in Garden Cove were in the bottom of the boat channel running through Garden Cove. There were no corals observed on the grass flats and in shallower areas of Garden Cove. The corals occurring in the boat channel are in isolated colonies of less than a foot in diameter. The Petitioners and Intervenors attempted to raise the possibility of synergistic adverse effects on corals posed by combinations of oils, oxygen levels, temperatures and sedimentation or similar impacts. It was not shown how or at what concentration turbidity might combine with various oxygen levels, temperatures or degrees of light penetration to produce such effects, however. The only type of synergistic effects on corals Drs. Glynn and Corcoran have observed is that between oils and pesticides. Although this effect has been demonstrated in another study area far removed from the Florida Keys, no such pesticide and oil synergistic impact has been observed in the Florida Keys area, chiefly because it is not an agricultural area characterized by significant use of pesticides. Likewise it was not established that suspended sediments in the Garden Cove area could have an adverse effect on corals by reducing light penetration. In tropical areas such as the Keys, light penetration is often saturating or in greater quantities than are really needed for healthy coral growth and indeed, many corals in these areas have pigments that naturally shield them from excess light because these coral species actually can suffer from too much light penetration. Additionally, Dr. Glynn has observed good coral reef health and growth in areas that are highly turbid. It was not established that an increase of sedimentation deposit on corals will necessarily have an adverse impact, particularly because most corals can accept a substantial amount of fine-grain sediment deposition without adverse effect. The manner in which the proposed marina modifications will be accomplished will minimize sedimentation at any rate since the canal will be dammed off from Garden Cove until all work is completed and all sedimentation within the marina and marina access canal has subsided to levels compatible with the state standards for turbidity. In any event, there is no evidence that boat traffic in Garden Cove at the present time influences the distribution and health of live coral, particularly since the main coral abundance in Garden Cove occurs in the heavily-used boat channel at the present time. Likewise, Dr. Glynn established that sediments from any increase in boat traffic in Garden Cove will not likely drift out on the offshore reef tract and be deposited on the reefs to their detriment in any event, since the fine sediments occurring in Hawk Channel and in Garden Cove, are largely precluded from deposition on the offshore reefs because the waters over the reef tract offshore have very different physical characteristics. That is, there is distinct interface between the inshore and oceanic waters caused by the strong wave assault and current action near the reefs, which precludes the fine sediments from the inshore areas remaining in the area of the reefs. Finally, any increase in the number of people visiting the Pennekamp Park attributable to use of the modified marina will not inevitably lead to degradation of the reefs. By way of comparison, studies of Kaneoi Bay in Hawaii where a major pollutant source from human sewage caused degradation of the coral reefs, showed that when sewage effluent was subsequently directed away from the reefs, the reefs rejuvenated and repopulated and are now used extensively for recreational activities without observable biological degradation. These studies are consistent with studies Dr. Glynn referenced with regard to Biscayne Bay National Park, which have shown no significant degradation occasioned by human visitation of the reefs in that park. Those studies have not shown a significant difference between the health of the "controlled reefs" and the reefs which are allowed to be used for recreational purposes. It was thus not established that there will be any degradation of the corals in the near-shore areas of Garden Cove nor in the offshore reef areas occasioned by any increased boat traffic resulting from the modification of the marina. Indeed, it was not demonstrated that the mere modification of the marina, which will actually accommodate fewer boats than are presently permitted, will cause any increase in present boat traffic at all. Dr. Glynn, in the course of his teaching and studies in the field of marine ecology has become familiar with the causes and effects of Ciguatera toxin in marine environments. He recently participated in the study of possible Ciguatera toxin at the grounding site of the freighter Wildwood on Molasses Reef, some miles distant from the marina site. All cases reported of such harmful concentrations of this toxin have originated from open water, outer coral reef environments, and not from near shore areas such as those involved in this case, where seagrasses and mangroves are the dominant marine communities. Ciguatera toxin organisms require clear open ocean water with strong currents and well-developed coral reefs which are found offshore in the Keys and not in the near-shore mangrove-type environments. The cause of Ciguatera is a concentration of toxin in the food chain. Although the bacteria that cause Ciguatera Toxin in fish, and resulting harmful effects in humans, occur everywhere in marine waters, the bacteria are not a hazard because generally, conditions are not appropriate for the bacteria to multiply. The two main species of dinoflagellates, that have been associated with causing Ciguatera poisoning do not occur in an environment such as the Port Bougainville Marina. They are typically concentrated in larger fish such as snapper, grouper and barracudas which cause problems when they are eaten by people. These species are not generally found in the inshore mangrove and grassbed areas such as are involved in the case at bar. Thus, the concerns expressed by Petitioner's witnesses concerning the possibility of Ciguatera poisoning occurring because of possible damage to corals and coral death caused by the dredge and fill operations, and boat operation associated with the marina and Garden Cove are, in reality, only unsubstantiated speculation.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, RECOMMENDED: That the State of Florida, Department of Environmental Regulation, issue the requested permit subject to the conditions incorporated in the agreement or "conservation easement" executed between the Department and the Respondents with the further condition added to that conservation easement such that the deposition of boats from the inland lakes system into the marina and its access canal be prohibited.

Findings Of Fact The Guana River Marsh Aquatic Preserve (the Preserve) is state-owned property. Title is held by the Board of Trustees of the Internal Improvement Trust Fund. It includes some 13 miles of Atlantic Ocean beach within St. Johns County. Within the boundaries of the Preserve is included the Guana River State Park (the Park). It, too, is state-owned. It is managed and operated by the Division of Recreation and Parks (the DRP) of the Department of Environmental Protection (the DEP). Some of the Preserve's Atlantic Ocean beaches are included within the boundaries of the Park. The "wet sand," or "hard sand," area of the Atlantic Ocean beaches in the Preserve is the area of the beach between mean high water and mean low water. The mean high water line is essentially the landward extent of the ocean at mean high tide; the mean low water line is essentially the landward extent of the ocean at mean low tide. When the tide is low, this entire area of the beach is exposed. It remains wet and, generally, relatively hard-packed during the time it is exposed. However, there are beds of "red shell" in this part of the beach that are softer. In the summer, this part of the beach averages approximately 50 feet in width. In the winter, when the waves and tides generally are higher, it is narrower. In the Preserve, the mean high water line usually is indicated both by debris washed up during the highest tides and left on the beach and by a "shelf." This "shelf," made by the erosive action of the ocean waves during the highest tides and during storms, rises at an angle of approximately 45 degrees and can be from one to four or five feet high. Landward of this shelf is the "dry sand" or "soft sand" beach, also sometimes referred to as the "upper beach." It extends landward from the mean high water line to the vegetation line, where the dunes start. Usually, some pioneer vegetation is found in the uppermost reaches of this part of the beach, forming what is called the "foredune" area of the beach. The tides along the Atlantic Ocean beaches in the Preserve are semi- diurnal, i.e., there usually are two high tides and two low tides a day. These high and low tides last approximately one hour, and each day they occur approximately an hour later than they did the day before. There are five beach access points with motor vehicle parking areas located along U.S. Highway A1A within the Preserve. Three are within the Park. There is parking for approximately 120, 68, 79, 42 and 25 vehicles in these five parking areas. There also is a current proposal for the addition of three more access points in the Park, with parking for a total of 340 vehicles, five beach bathhouses, and five pedestrian overpasses. There are many other places where pedestrians can walk from A1A to the beaches, including 30 County-controlled access points. But there are no lawful parking areas adjacent to any of these other access points at this time, and parking on the right-of-way of A1A is prohibited. Currently, the only lawful motor vehicle access to the Atlantic Ocean beaches in the Preserve is to the south of the Preserve. Prior to the agency action challenged in these proceedings, motor vehicles lawfully could be driven onto the beach at this access point and be driven north into the Preserve, so long as they remained below the mean high water line. A former access near the north end of the Preserve has been cordoned off. To leave the Preserve, motor vehicles would have to be turned around and driven back south to the same motor vehicle access point. Due to the restricted access to the Atlantic Ocean beaches in the Preserve, not much use is made of those beaches. In comparison, beaches to the south are used much more heavily. Of the relatively few who use the motor vehicle access to the south and drive on the beach north through the Preserve, some ultimately use the beaches to picnic, swim, surf, beach-comb and similar activities; some probably just drive on the beach. There was no evidence quantifying the uses currently being made of the beaches in the Preserve. In the past, homemade motor vehicles called "skeeters" were built with a light-weight chassis and over-sized wheels. They were used for driving on both the hard and soft areas of the beaches, as well as illegally in the dunes. This practice has been curtailed due to better enforcement of the prohibitions against driving in the dunes, a generally heightened environmental consciousness among the public, and prohibitions against driving the "skeeters" on public highways. Generally, there has been less driving on the beaches of the Preserve in recent years, although the practice persists at a reduced level. At all times of the year, it sometimes is impossible to drive along the entire length of the beaches in the Preserve without driving on the soft sand area. This is especially true during the winter months when the waves and tides are higher and storms are more frequent. But even in the summer months, there are times when "red shell beds" in the "wet sand" part of the beach must be circumvented to avoid getting stuck. Especially when the tide is not at its lowest, the only way to avoid some of these "red shell" beds is to drive over the "shelf" and onto the "soft sand." Depending on the tides, this may also be necessary in order to turn a vehicle around on the beach. In many places, the "soft sand" area is not very wide, and it would be necessary under those circumstances to drive in the "foredune" area. The times of the daily high and low tides can be obtained relatively easily by members of the public. But there is no assurance that all persons who would drive on the beaches would know the times of the tides. Nor is there any assurance that persons who drive the "wet sand" or "hard sand" part of the beaches at low tide also would plan to both start their beach drive and their return trip during low enough tides to be able to avoid driving on the "soft sand" part of the beach. For these and other reasons, it would be difficult, if not practically impossible, to effectively monitor beach driving throughout the Preserve and consistently enforce a restriction to driving only on the "wet sand" or "hard sand" areas of the beach. In the summer months, sea turtles lay eggs in nests dug in the sand of the foredune and dune areas of the Atlantic Ocean beaches in the Preserve. After a period of incubation in the nests, the turtle hatchlings dig themselves out of the nests and crawl to the ocean to begin their lives in the sea. Driving motor vehicles over nests on those parts of the beaches in the summer months could crush eggs in their nests or pack the sand hard enough to reduce the number of hatchlings that emerge from the nest alive. In addition, driving motor vehicles in these area, even in other parts of the year, can leave ruts in the beach that disorient hatchlings that leave the nests in summer so that fewer reach the ocean alive. Sea turtles crawl out of the ocean to their nest sites at night. Artificial lighting can disturb their nesting and egg-laying activities. However, it seems that moving lights, or lights that turn on and off (in the manner of car lights), create more of a disturbance than stationary lights, such as those more often found at residences along the beaches in the Preserve. The Management Plan does not prohibit artificial lighting along the beaches in the Preserve, but it recommends that further attention be given to this problem and that ways to address the problem be explored and pursued in cooperation with the County. Various shore birds, including the threatened least tern, make their nests in the foredune area of the beaches in the Preserve. Driving on the foredunes destroys and disturbs nesting habitat and disturbs the nesting activities of these birds. In addition, both these ground nesting shore birds and a variety of migratory birds make use of different areas of the beaches to rest and feed. Driving on the beaches disturbs these activities, as well. The only known nesting colony of least terns in St. Johns County is located in the Park, where beach driving is prohibited. The Division of Parks and Recreation (DPR) of the Department of Environmental Protection (DEP) has utilized F.A.C. Rule 16D-2.002(4)-(5) to prohibit driving or parking motor vehicles on the beaches of the Park by not designating the beaches as driving or parking areas within the Park. At least parts of the beaches in the Park have been posted as areas where driving motor vehicles is prohibited. In order to develop a management plan for the Preserve, the manager of the Preserve personally researched the geology, climate and natural resources of the Preserve, as well as the records of the County, and also collected data pertaining to the Preserve from several state agencies. Over the course of a year, the manager's input was taken into consideration, and a management plan, called the Guana River Marsh Aquatic Preserve Management Plan (the Management Plan), was developed for the Preserve. It was adopted by the Board of Trustees of the Internal Improvement Trust Fund on December 17, 1991. The Management Plan recites in pertinent part: At the present time, motorized vehicular traffic is permitted, by county ordinance, below the natural vegetation line on the beaches adjacent to the Atlantic Ocean in St. Johns County. Vehicles are not allowed on the 4.2 miles of beach within Guana River State Park. The coarse coquina sand and steep profiles of the beaches in the preserve make driving on the wet sand area difficult. Drivers are forced to cross the dry sand area, damaging the foredunes, pioneer dune vegetation and sea turtle nesting habitat. Due to the negative environmental impacts resulting from this activity, motorized vehicular traffic shall not be considered an authorized activity on sovereign submerged lands within [Prime Resource Protection Area] PRPA beach management areas of the preserve, and therefore will be prohibited. Under the Management Plan, all of the Atlantic Ocean beaches in the Preserve are Prime Resource Protection Area, and the driving of motorized vehicles on them is prohibited. On June 11, 1993, the DEP's DRP sent St. Johns County a letter advising that, based on the Management Plan, DEP no longer would permit the driving of motor vehicles on the Atlantic Ocean beaches in the Preserve. The proposed amendment to F.A.C. Rule 18-20.004(7), incorporating the Management Plan, was noticed in the Florida Administrative Weekly on August 6, 1993. On or about August 18, 1993, the DEP agreed not to enforce the beach driving prohibition in the Preserve until these cases are resolved.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Respondent, the Department of Environmental Protection enter a final order enforcing the prohibitions contained in both F.A.C. Rule 16D-2.002(4)-(5) and the proposed amendment to F.A.C. Rule 18-20.004 against the driving of motor vehicles on the beaches on the Atlantic Ocean beaches in St. Johns County that are within the Guana River Marsh Aquatic Preserve.

APPENDIX TO RECOMMENDED ORDER, CASE NO. 93-3970 To comply with the requirements of Section 120.59(2), Fla. Stat. (1991), the following rulings are made on the parties' proposed findings of fact: Petitioner's Proposed Findings of Fact. 1. Accepted and incorporated. 2.-6. Accepted and incorporated to the extent not subordinate or unnecessary. 7. Subordinate and unnecessary. 8.-9. Accepted and incorporated to the extent not subordinate or unnecessary. First sentence, rejected as not proven. There also is access by boat and, albeit over longer distances, by foot. Accepted and incorporated to the extent not subordinate or unnecessary. Accepted in part and rejected in part, as reflected in the Findings of Fact. Accepted as representative of dead low tide. Subordinate and unnecessary. Accepted and incorporated. Rejected in part: in that there are "red shell beds" in summer, too, and they can force drivers onto the "soft sand" areas in summer, too, depending on the tides; in that "dramatically" is argument and not proven; and in that Exhibit 2 depicts dead low tide in summer. Accepted but subordinate and unnecessary. Rejected as not proven. (Enforcement of such mitigation would be impracticable or impossible.) Accepted but subordinate and unnecessary. Accepted and incorporated. 20.-21. First sentence, accepted and incorporated. Second sentence, accepted that the County uses "due care," but enforcement of a prohibition against driving anywhere except on the "hard sand" is impracticable or impossible. Rejected as not proven. Accepted but subordinate and unnecessary. Rejected as not proven that there is "no way to get to many beach areas" or that limited access "restricts traditional use." (Access as limited, or more limited, is "traditional.") 25.-27. Accepted and incorporated. Rejected as not proven. (How easy it is depends entirely on the tide, the number and location of people on the beach, and the presence of "red shell" beds.) Accepted and incorporated. Respondent's Proposed Findings of Fact. 1.-3. Accepted and incorporated except to the extent conclusion of law and unnecessary. Accepted and incorporated. Accepted but subordinate and unnecessary. 6.-20. Accepted and incorporated to the extent not concluson of law, subordinate or unnecessary. 21.-24. Rejected as being conclusion of law. 25.-33.
