Findings Of Fact It is stipulated that Marine Industries Association of South Florida, Inc. (Petitioner), has standing to bring this rule challenge. It is also stipulated that Save The Manatee Club, Inc. (Intervenor), has standing to intervene in this rule challenge. The Department of Environmental Protection (Respondent) has the responsibility of implementing the Florida Manatee Sanctuary Act, Section 370.12(2), Florida Statutes, which involves interpreting the terms thereof. Respondent's responsibility includes promulgating rules to regulate motorboat speeds and their operation incident to the protection of manatees, pursuant to the Act. 4. Respondent's Rules 16N-22.001(2), 16N-22.002(20) and (21), Florida Administrative Code, set forth criteria for determining the state waters in which motorboat speed would be regulated for the protection of manatees. Also, Respondent's Rules 16N-22.010(1)(e) and (g), Florida Administrative Code, establish a seasonal slow speed zone on weekends for a certain area in the Intracoastal Waterway within Broward County and a year-round slow speed and buffer zone in a certain area in the Atlantic Intracoastal Waterway within Broward County for the protection of manatees. The manatee is an endangered marine mammal residing in the southern United States, principally in Florida, and has been declared by the State of Florida as its state marine mammal. Only 900 manatees are considered to be on the east coast of Florida. Respondent uses all available information on the presence of manatees, which includes actual visual sightings as well as any other method to identify their presence. Respondent refers to this information as "sightings." Respondent's information gathering procedure is consistent with established and accepted procedures for the gathering of information on manatees. Aerial surveys are part of the information relied upon by Respondent for its determinations regarding manatees. It is possible, and not uncommon, that aerial surveys may include sightings of the same mammal on different days. Whether a manatee is sighted frequently involves more than just numbers. It also includes a reasonable expectation that manatees will be seen. Aerial survey data is a minimum count to ascertain where the manatees are, not to determine how many exist or their population. Sixty-one aerial surveys were conducted in the waters of Broward County, excluding the Hillsboro Inlet, by Respondent and Broward County for Respondent. During the aerial surveys from 1988 to 1993, sixty-seven to sixty- nine sightings were made in the northern Intracoastal Waterway (NICW) in Broward County. Also, the aerial survey data showed sightings in seven out of twelve, five out of fifteen, and eleven out of eighteen flights. Manatees occasionally travel in the ocean. The aerial surveys included passes over the Atlantic Ocean. The NICW has lowlight transmission and high turbidity. Manatees travel two to five feet below the surface of the water. Because of water clarity, surface conditions and the fact that manatees must be at or very near the surface to be spotted, manatees are difficult to see in the NICW. The aerial surveys revealed an average of one sighting per flight. Lack of sightings in the aerial surveys reflect survey conditions as much as the absence of manatees. Manatees regularly move in and out of the Hillsboro Inlet zone. Manatees use the NICW in Broward County often and are frequently sighted there. When determining whether manatees inhabit an area, all data bases available should be used. The Intracoastal Waterway (ICW) is used by manatees for travel through Broward County. Aerial surveys of the NICW are performed at a lesser density than those performed of the power plants which are warm water refuges. Regular travel corridors constitute essential habitat. The NICW is a major travel corridor for manatees. They migrate through the NICW. Migration means purposeful movement from one point to another, as well as seasonal movement of species in mass. Manatees use the waters of the NICW and the power plants when moving back and forth between Port Everglades and Riviera Beach, and this exchange is documented. More than 200 manatees use both the Port Everglades and the Riviera Beach Power Plants (both warm water discharge areas) as warm water refuges, making repeated trips back and forth in single seasons. Thirty-Eight to forty-seven percent of manatees on the east coast use the Port Everglades area. Manatees inhabit areas where they are found. As to the waters of the ICW, they inhabit it on a regular basis. Moreover, manatees inhabit the NICW virtually continuously in winter and regularly or periodically in the off-winter months. Manatees inhabit Broward County year round, continuously in the winter months and regularly in the off-winter months. Although to a lesser degree, Respondent considers radio telemetry data in its determinations regarding manatees. Radio telemetry is a data gathering technique which is not experimental, but is less revealing when used with manatees. Telemetry data is hard to acquire in the NICW because manatees' behavior of resting and traveling deploys the tag being used in a way which is not available to the satellite. As a result, every tagged manatee is not seen on every satellite pass. Data from telemetry studies show that manatees predominantly travel the ICW, and extremely infrequently in the ocean, and have a regular exchange between the Port Everglades and Riviera Beach plants. Tagged manatees, when located visually, are found in association with others. The behavior of radio-tagged manatees is representative of the population of manatees as a whole. Manatees travel in groups in the NICW. A congregation of mammals means more than one mammal together, without assigning a reason for the congregation. Manatees congregate in areas where they are sighted in groups of two to three or more. All of the available information taken together indicates that manatees congregate in the NICW, using it on a regular and frequent basis. Respondent considers the entire NICW, including the Hillsboro Inlet zone, as a single unit when interpreting manatee sightings because of the types of manatee behavior observed and the character of the NICW. Respondent also considers anecdotal data in its determinations regarding manatees. Anecdotal data is useful for confirmation of, but not for providing new insights about manatees and their behavior. Anecdotal sighting data are consistent with and confirm what is known by Respondent from other sources about manatees. Motorboats kill, maim and disturb manatees. Manatees have scars on their bodies, which are caused by collisions with watercraft. Virtually all manatees have propeller scars and approximately 900 are documented in what is known as the Scar Catalogue. Scar patterns on manatees indicate numerous collisions, some nine to ten times. The Scar Catalogue also indicates that manatees move back and forth between the Port Everglades and Riviera Beach plants. Since 1974, when Respondent started compiling manatee mortality data, of the manatees recovered for which the cause of death could be determined, 522 were attributed to watercraft collision. Of the 522 watercraft collision deaths, twenty-seven manatees were recovered in Broward County, which represents over one-half of the total manatee deaths in Broward County for which the cause of death could be determined. However, the recovery data fails, and is unable, to show where within the ICW or NICW the manatees were struck. After a collision, manatees will seek out a quiet area. It is not unusual and is expected that injured manatees in Broward County will seek refuge at the Port Everglades. Boat traffic poses a threat to manatees. Increased or higher boat traffic poses an elevated or even greater risk to manatees. Broward County waters are utilized by large numbers of boaters. In addition to Broward boaters whose boat registrations have increased eighteen percent between 1986 and 1991, boaters from Dade and Palm Beach Counties and in winter from out-of-state use Broward waters. Boating traffic in Broward County and the NICW is heavier on weekends than on weekdays. There is no change in the traffic for Broward County in the winter months from November through March. More boating occurs during the day than at night on the NICW. A survey of boaters in Broward County relied upon by Respondent indicated that over fifty percent of boaters leave between 8:00 a.m. and noon and return between 2:00 p.m. and 6:00 p.m.; that eighty-four percent of those surveyed were in favor of speed limits to protect manatees; and that fifty-nine percent of those surveyed were in favor of slow speed for the whole county on weekends and holidays from November to March. Comparatively, Respondent's slow speed rule is substantially less stringent than that which was found acceptable by those surveyed and not as stringent as recommended by the federal Fish and Wildlife Service. Several local governments in the NICW adopted resolutions calling for more stringent regulations than Respondent's rule. In an effort to lessen the interference with boaters while also providing an area of protection for manatees in the NICW, the 25 mph speed limit with the fifty-foot buffer zone was adopted. A slow speed zone in the NICW will enhance boating safety. At slow speed, only boats with propeller-on-shaft and a rudder will exhibit an unsafe condition referred to as wobbling. However, virtually no typical recreation boat which is under thirty feet is configured that way.
The Issue The issue is whether proposed regulations for Brevard County manatee protection areas by the Florida Fish and Wildlife Conservation Commission (FWCC), which are amendments to Rule 68C- 22.006, Florida Administrative Code, noticed in the April 20, 2001, Florida Administrative Weekly (F.A.W.)("Proposed Rule"), with a Notice of Change published in the F.A.W. on June 15, 2001, are an invalid exercise of legislative authority.
Findings Of Fact Based upon observation of the witnesses and their demeanor while testifying, the documentary evidence received, and the entire record compiled herein, the following material and relevant facts are found. Effective July 1, 1999, Respondent, FWCC became primarily responsible for implementation of the Florida Manatee Sanctuary Act, Section 370.12(2), Florida Statutes (2000) instead of the Department of Environmental Protection, by operation of Section 45, Chapter 99-245, Laws of Florida. FWCC is the State agency responsible for promulgating rules pursuant to Section 370.12, Florida Statutes. Respondent noticed proposed rules, and is a mandatory party to a challenge thereto. Section 120.56(1)(e), Florida Statutes. STANDING OF THE PARTIES McGill, Pritchard, Dovark, Gentile, Akins, Mason, Jaren, Robertson, Standing Watch, Inc., Save the Manatee Club, Inc., Florida Wildlife Federation, Inc., and Sea Ray Boats, Inc.1, are substantially affected by one or more of the Proposed Rules in that they operate motorboats in one or more of the areas proposed for regulation, or in that they represent the interests of members who operate motorboats in one or more of the areas proposed for regulations, or who desire to protect manatees and manatee habitats on behalf of members who derive aesthetic or other benefits from manatees, and who observe or otherwise enjoy manatees in Brevard County and elsewhere. Intervenor, Florida Power and Light Company (FPL), is a Florida corporation that owns and operates the Cape Canaveral Power Plant located in Cocoa, Brevard County, Florida. FPL's operations are specifically addressed in the proposed rule in that the proposed rule creates a no-entry zone along an area bordering the FPL Cape Canaveral Power Plant property boundary including easements and right-of-way where electrical generation operating equipment and electrical distribution and transmission equipment are located. Intervenor, Cocoa Beach is a Florida Municipal Corporation located in Brevard County. The Cocoa Beach Sports Area located with the Banana River Lagoon has been designated since 1988 as an area for water-related recreational activities for the residents of the City of Cocoa Beach and for the general public. The Proposed Rule seeks to impose speed restrictions for boats operating within this area and, if promulgated, will directly regulate and restrict the boating, fishing and other water-related recreational activities of the public within the area. Intervenor, Titusville is a Florida Municipal Corporation located in Brevard County, whose elected body has determined that a substantial number of its residents are substantially affected in the Proposed Rule. The parties alleged facts supported their standing in individual petitions, and the parties stipulated to standing. Therefore, none of the Petitioners presented any evidence regarding their standing. Petitioners and Intervenors are substantially affected by one or more sections of the proposed rule in that they operate motorboats in one or more of the areas proposed for regulation, or they represent the interests of members who operate motorboats in one or more of the areas proposed for regulation or who desire to protect the manatees and manatee habitat on behalf of members who derive aesthetic or other benefits from manatees and who observe or otherwise enjoy manatees in Brevard County. ADOPTION PROCESS FOR THE 2001 RULE PROPOSAL On September 6, 2000, the Commission authorized staff to initiate amendments to the Brevard County rules at a public meeting in Deland, Florida. On October 6, 2000, the Commission published a Notice of Rule Development in the Florida Administrative Weekly and announced a rule development workshop. On October 26, 2000, the Commission staff conducted a rule development workshop in Melbourne, Brevard County, Florida. On January 24, 2001, the Commission directed staff to conduct a second rule development workshop in Brevard County, Florida. On February 16, 2000, the Commission published notice in the Florida Administrative Weekly of the rule development workshop scheduled for March 7, 2000. On March 7, 2000, the Commission staff conducted a second rule development workshop in Viera, Brevard County, Florida. On March 30, 2000, the Commission conducted a public meeting in Tallahassee, Florida, and authorized publication of a Notice of Proposed Rulemaking in the Florida Administrative Weekly. On April 20, 2001, the Commission published a Notice of Proposed Rulemaking in the Florida Administrative Weekly and advertised public hearings to be held on May 3 and May 23, 2001. On May 3, 2001, the Commission staff conducted a public hearing on the Proposed Rule in Melbourne, Brevard County, Florida. On May 23, 2001, the Commission staff conducted a public hearing on the Proposed Rule in Melbourne, Brevard County, Florida. On June 15, 2001, a Notice of Change was published in the Florida Administrative Weekly. There are no algorithms, formulae, protocols, matrices, math models, or metrics used by the Commission to combine the individual data sources into findings that idle-speed, slow-speed, or no-entry zones were required for any specific zone in question. Aerial surveys have been conducted by the Florida Marine Research Institute (FMRI) and others. One type of aerial survey technique is a statewide survey. These surveys are typically flown in the winter, after the passage of a cold front. Typical winter aggregation areas are included in these surveys. The synoptic surveys are used for monitoring winter aggregations of manatees. Population biologists working on manatee recovery view synoptic survey results as the best available information about the minimum estimated size of the manatee population in Florida at this time. The statewide synoptic survey data from the past several years is as follows: 1991 1,268 manatees 1991 1,465 manatees 1992 1,856 manatees 1995 1,443 manatees 1995 1,822 manatees 1996 2,274 manatees 1996 2,639 manatees 1997 2,229 manatees 1997 1,709 manatees 1998 2,022 manatees 1999 2,034 manatees 1999 2,354 manatees 2000 1,629 manatees 2000 2,222 manatees 2001 3,276 manatees During the most recent statewide synoptic survey, portions of Brevard County were observed in five counts made during January 5, 6, and 7, 2001. Of the 591 manatees observed in Brevard County on January 6, 2001, 457 manatees were adjacent to Florida Power and Light Company's thermal discharge, 38 manatees were in Sebastian River, 16 manatees were in Berkley Canal System, and 8 manatees were along the east Banana River shoreline on the southeastern extension of Merritt Island. In addition to statewide surveys, targeted aerial surveys in specific areas are used to establish manatee distribution and relative manatee abundance. These types of surveys are used by the FWCC in assessing manatee use of an area and then establishing manatee protection regulations. The most recent, comprehensive FMRI aerial survey in Brevard County consisted of 45 flights between September 1997 and September 1999. A standardized flight path designed to cover most probable manatee habitats was flown over Brevard County at least once per month during the two-year period at an altitude of approximately 500 feet (except for June 1999, where excessive smoke covered the area); the only area of the county not covered at all was restricted airspace associated with the Kennedy Space Center Complex. The highest number of manatees counted during this survey was 790 manatees in March 1999. General Description of Brevard County. Located in east central Florida, Brevard County is approximately 72 miles north-south and approximately 20 miles east-west. The west boundary of the county is the St. Johns River; the east boundary is the Atlantic Ocean. The Indian River Lagoon in Brevard County extends north of the Kennedy Space Center, at the north end of the county, to Sebastian Inlet, at the south end of the county. Brevard County consists of two major landforms and two major surface waters. From east to west, the geographical features are the Atlantic Ocean, a barrier island running the length of the county, the Indian River Lagoon, and the mainland. Northern Brevard County contains two other major geographical features. The barrier widens to form the Canaveral Peninsula on the east and Merritt Island on the west. Merritt Island is bordered by the Indian River on the west; the Banana River on the east; and the Mosquito Lagoon on the north. At the southern end of Merritt Island, the Banana River joins the Indian River. Besides Sebastian Inlet at the southern boundary of the county, the only navigable connection between the Indian River Lagoon and the Atlantic Ocean is at Port Canaveral. Port Canaveral cuts across the Canaveral Peninsula; along the west shoreline, the Canaveral Locks permit vessels to pass from the Port into the Banana River. The Mosquito Lagoon, Indian River and Banana River are located in a transitional zone between the temperate and tropical zones and form one of the most diverse estuaries in North America. The Indian River Lagoon varies from 0.5 to 5 miles in width and has an average depth of one meter (39.4 inches). The Indian River Lagoon system is not subject to significant periodic lunar tides. The water depths are depicted as mean lower low water, while the shorelines are represented in terms of approximate mean high water. In the lagoon system in Brevard County, the relative water levels rise and fall as influenced by wind, rainfall, storms, and tides. Expert witnesses with local knowledge of the waters acknowledged the variation in water level or relative depth and testified that the water level fluctuates in the Indian River Lagoon by more than three feet and fluctuates by two or two and one-half feet or greater annually. The Indian River Lagoon contains extensive sea grass beds, which are the preferred food for manatees. A bathymetric survey commissioned by the St. Johns River Water Management District determined the acreage of submerged land within the lagoon that can be potentially vegetated with submerged aquatic vegetation at a depth of six feet below mean sea level. Brevard County is the hub of the Atlantic Coast manatee population with a large year-round and a large migratory transient manatee population present throughout the year. THE MANATEE The West Indian manatee (Trichechus manatus) is one of endangered marine mammals in coastal waters of the United States. The West Indian manatee is presently classified as an "endangered species" by the federal Endangered Species Act and has protected status under the Marine Mammal Protection Act. The West Indian Manatee is one of the four living species of the mammalian Order Sirenia, the other three are the West African manatee, the Amazonian manatee and the dugong; the fifth species, Stellar's sea cow, was hunted into extinction. In the southeastern United States, manatees are limited primarily to Florida and Georgia and this group forms a separate subspecies called the Florida manatee (T. manatus latirostris). The Florida manatee (hereinafter "manatee") is a migratory species with a large range of movement along the Atlantic and Gulf Coasts of the United States. During the winter, cold temperatures keep the population concentrated in peninsular Florida, but during the late spring and summer they expand their range and are seen infrequently as far north as Rhode Island, and as far west as Texas. Manatees demonstrate "site fidelity" with some individual mammals adjusting their behavior to take advantage of changes in the availability of resources. Manatees often return to the same winter thermal refuges and the same summer habitats year after year. Manatees prefer water temperatures above 68 degrees F and when ambient water temperatures drop below 68 degrees, they seek warm water refuges, such as spring-fed rivers and power plans discharge outs. Florida Power and Light Company and Reliant Energy Power Plants and the Sebastian River are the primary warm water refuges sought by manatees in Brevard County. For feeding, resting, cavorting, mating and calving, manatees prefer shallow sea grass beds in coastal and riverline habitats with ready access to deep channels, particularly near the mouths of creeks, embayments and lagoons. Manatees sometimes prefer vegetation growing along the banks of waterways, instead of submerged or floating aquatic vegetation. Manatees seek and find sources of fresh water for drinking. In brackish or estuarine environment, they locate fresh water sources, either natural or artificial. They have been observed drinking fresh water at marinas, from air conditioning condensate discharge, from pockets of fresh water floating on the surface of the saltier water, from storm water outfalls and from springs. Typically, six-to-eight hours per day are spent on feeding, usually at one-hour intervals. Intermittently, between two and 12 hours per day are spent resting or sleeping either at the surface of the water or on the bottom. Time not devoted to feeding or sleeping is spent in traveling, socializing or exploring during both day and nighttime hours. The basic social unit consists of a female manatee and her dependent calf. Manatees, apart from winter aggregations at warm water resources and transient mating herds, are semi-social or mildly social mammals. Manatees usually prefer to swim below the surface at one to three meters (3.28 to 9.84 feet) depth, surfacing every few minutes to breathe. They typically have a swimming cruising speed between four and ten KM/HR (2-6 MPH), but can swim in short bursts at up to 25 KM/HR (15 MPH). Manatees have been seen in shallow waters with their backs and heads out of the water and on occasion have been observed fully or partially out of the water to feed or escape pursuing male manatees. Female manatees reach sexual maturity by age five years and males at the age of three to four years. Mating occurs when estrous females are successfully approached by dynamic epherimal mating herds of between five and 20 males (lasting up to four weeks). Female manatees will swim to very shallow water when pursued by mating herds of males as a preventive measure from mating. Manatees have a low reproductive rate and a long life expectancy. Manatee's gestation period is 11 to 14 months with usual birthing of one calf. Dependent calves remain near their mother's side from one to two years, swimming parallel to its mother, directly behind her flipper. Life expectancy for a manatee is in excess of 50 years. A significant decrease in adult survivorship due to, among other things, watercraft collisions could contribute to a long-term population decline. The manatee population in Florida has shown yearly increases resulting in more manatees now than there were in 1976 in the areas of Brevard County that are subject to the Proposed Rules. MANATEE PROTECTION PLANS The United States Fish and Wildlife Service developed an initial recovery plan for West Indian manatees in 1980, primarily for manatees in Florida. The plan was revised in 1989 and 1996. A third revision to the Recovery Plan was noticed for public comment in November 2000, and in July 2001. The recovery plans hereinabove recognized the major human-related cause of manatee mortality is collisions with watercraft. The existing and draft recovery plans state: Because watercraft operators cannot reliably detect and avoid hitting manatees, federal and state managers have sought to limit watercraft speed in areas manatees are most likely to occur to afford boaters and manatees time to avoid collisions. Avoidance technology research is ongoing for deterrent devices designed to "avoid collisions"; however, no device or combination of devices has gained acceptance and approval by the Marine Biological Scientific Community. The Florida Legislature has designated the entire State a refuge and sanctuary for the manatee--the Florida State marine mammal. Section 370.12(2)(b), Florida Statutes. HISTORY OF MANATEE PROTECTION IN BREVARD COUNTY The Florida Legislature initially authorized the adoption of manatee protection rules for Brevard County effective July 1, 1978, when it required the (former) Florida Department of Natural Resources to adopt rules regulating the speed and operation of motorboats between November 15 and March 31, 1978, in those portions of the Indian River within 3/4 mile of the then Orlando Utilities Commission (now Reliant) and Florida Power and Light Company power plant effluents. These rules became effective on March 19, 1997 (former Rule 16N-22.06, Florida Administrative Code ("Brevard County Manatee Protection Rules" or "BCMPR"). In 1989, a strategy to improve manatee protection in 13 key counties was approved by the Governor and Cabinet. The strategy called for development of manatee protection plans, for boat facility siting criteria, for priority land acquisition of critical manatee use areas, and improved aquatic preserve management for sea grass protection. Guidelines for implementation included new or expanded speed zones, refuges or sanctuaries for the regulation of boat speeds in critical manatee areas. Financial assistance was given Brevard County for its manatee protection plan in 1993. After creation of the FWCC, effective July 1, 1999, the BCMPR and other manatee protection rules were transferred from Florida Department of Environmental Protection (FDEP) to the FWCC, and the Secretary of State renumbered the prior rules to Chapter 68C-22, Florida Administrative Code. In 1994, FDEP amended BCMPR to establish manatee protection zones in the Canaveral Barge Canal and portions of adjacent areas of the Indian and Banana Rivers; to expand the existing "slow speed" zone in Sykes Creek (north of "S Curve") to include the channel; to establish a maximum 25 MPH zone in the Sykes Creek channel between Sykes Creek Parkway and the "S Curve"; and to renumber and correct map inconsistencies. This site- specific rule-making action was taken in response to proposed additional threats to manatees resulting from development of Abby Marina (now Harbortown Marina), pending completion of Brevard County comprehensive countywide manatee protection plan. In 1998, FDEP amended the BCMPR to establish seasonal "motorboats prohibited" and "no-entry" zones at the then Orlando Utilities Commission's (now Reliant) power plant and a seasonal "no-entry" zone at Florida Power and Light Company's power plant. THE PROPOSED MANATEE PROTECTION RULE AMENDMENTS FOR BREVARD COUNTY 1906 Section II - Proposed Rules THE FULL TEXT OF THE PROPOSED RULES IS: (Substantial rewording of Rule 68C-22.006 follows. See Florida Administrative Code for present text.) 68C-22.006 Brevard County Zones. The Commission hereby designates the waters within Brevard County, as described below, as areas where manatee sightings are frequent and where it can be assumed that manatees inhabit on a regular, periodic or continuous basis. The Commission has further determined that a likelihood of threat to manatees exists in these waters as a result of manatees and motorboats using the same areas. The primary purpose of this rule is to protect manatees from harmful collisions with motorboats and from harassment by regulating the speed and operation of motorboats within these designated areas. A secondary purpose is to protect manatee habitat. In balancing the rights of fishers, boaters, and water skiers to use these waterways for recreational and commercial purposes (as applicable under 370.12(2)(j), F.S.) with the need to provide manatee protection, the Commission has examined the need for unregulated areas or higher speed travel corridors through regulated areas. Such areas or corridors are provided in those locations where the Commission determined, on the basis of all available information, (1) there is a need for the area or corridor and (2) the area or corridor will not result in serious threats to manatees or their habitat. Unregulated areas or higher speed corridors are not provided in locations where both of the above findings were not made. The following year-round and seasonal zones are established, which shall include all associated and navigable tributaries, lakes, creeks, coves, bends, backwaters, canals, and boat basins unless otherwise designated or excluded. As used in this rule, ICW means the Intracoastal Waterway. Access to the NO ENTRY and MOTORBOATS PROHIBITED zones designated in paragraphs (2)(a) and (b) will be provided in accordance with procedures set forth in subsection (4), hereunder, and applicable provisions of Rule 68C-22.003.

DATA SOURCES CONSIDERED BY FWCC IN PROMULGATING THE PROPOSED RULE FWCC's staff who were primarily responsible for the development of the recommended revisions to the BCMPR to the FWCC included: Scott Calleson, who holds a Bachelor of Science degree in Marine Science and a Masters of Science degree with emphasis on Environmental Planning and Natural Resource Management, and has worked with manatee protection rules since 1992; David Arnold, who holds both a Bachelor of Science degree in Biology and a Master of Science degree in Biological Oceanography, and who supervised the Department of Environmental Protection's marine turtle protection program prior to becoming Chief of the Bureau of Protected Species Management in 1995; and Dr. Charles Deutsch, who has both a Bachelor of Science and a Doctorate degree in Biology with specialization in biology of marine mammals and behavior, animal behavior and behavioral ecology, and worked for the United States Geological Survey (USGS) in a number of analyses of manatee radio tracking along the Atlantic Coast. The verbal, narrative and graphical presentations of the experts were relied upon in making recommendations to the FWCC for the proposed rule revisions. FWCC's staff gave good faith consideration to the experts' opinions, publications, articles, data analysis, and reasonable inferences and predictions. MANATEE MORTALITY DATA FWCC relied upon manatee mortality data in evaluating manatee inhabitation (Brevard County Mortality Information and Brevard County Misc. Information), including FMRI manatee salvage database for Brevard County from January 1974 to December 2000 (including carcass recovery location and cause of death). AERIAL SURVEY DATA In evaluating manatee inhabitation, FWCC relied upon manatee aerial survey data in existing manatee inhabitations. Included in this process were: information on aerial surveys performed for Kennedy Space Center by Dynamic Corporation; Geographic Information System information for FMRI's 1997-1999 Brevard County aerial survey along with data in "Seasonal Manatee Distribution and Relative Abundance in Brevard County, Florida, 1997-1999"; Geographic Information System data from earlier Brevard County aerial surveys; and aerial surveys conducted by the Florida Marine Research Institute and others. Aerial Surveys Aerial surveys have been conducted by the Florida Marine Research Institute and others using various techniques. One type of aerial survey technique is a statewide survey. These surveys are typically flown in the winter, after the passage of a cold front. Typical winter aggregation areas are included in these surveys. The synoptic surveys are used for monitoring winter aggregations of manatees. Population biologists working on manatee recovery view synoptic survey results as the best available information about the minimum estimated size of the manatee population in Florida at this time. The statewide synoptic survey data from the past several years is as stated in Finding of Fact 23 herein above. In addition to statewide surveys, targeted aerial surveys in specific areas are used to establish manatee distribution and relative manatee abundance. The commission in assessing manatee use of an area and then establishing manatee protection regulations uses these types of surveys. SYNOPTIC AERIAL SURVEYS Considered by FWCC was the statewide synoptic survey for the period 1991 to 2001. These surveys are used for monitoring winter aggregation of manatees and provide a minimum estimate of the number of manatees observed. Population biologists view synoptic survey results as the best available information source to estimate the minimum size of the manatee population in Florida at the present time. The statewide synoptic survey data for the years 1991-2001 are detailed in paragraph 22 herein above. The Berkeley Canal system location, where manatees were observed on January 6, 2001, has four connecting canals to the eastern shoreline of the Banana River; the northernmost connection is just south of the Pineda Causeway and the southernmost connecting canal is located about three and three-fourths miles to the south between Carter's Cut and the Mathers Bridge. The West Banana River shoreline locations where manatees were observed on January 6, 2001, is the Banana River Marina. MANATEE DISTRIBUTION AND RELATIVE ABUNDANCE Targeted aerial surveys in specific areas are used to establish manatee distribution and relative manatee abundance. They are used in assessing manatee use of an area and then in establishing manatee protection regulations in those areas. Forty-five flights between September 1997 and September 1999 are the most comprehensive and recent FMRI aerial surveys in Brevard County. Aerial surveys possess an inherent bias because the location of animals can only be seen during daylight hours and do not account for nighttime locations. FWCC's aerial survey data were presented in various forms: raw data entry sheets completed by the surveyors; a composite, GSI plot of the data points for Brevard County; small- format GIS plots of data points that depicted manatees seen by month; and small-format GIS plots of data points that depicted manatees seen during each flight, along a flight path. Before the 1997-1999 Bervard survey, relative abundance and distribution surveys for portions of Brevard County were conducted in late-1985 through early-1987. The 1985-87 Banana River surveys included only the area between Launch Complex 39B and Eau Gallie, but included portions of Canaveral Barge Canal, Sykes Creek and Newfound Harbor. Flights were flown over the Cocoa Beach area during morning hours for a nine-month period (March 3, 1990- November 27, 1990), and showed more than one manatee during each flight, with one exception on March 3, 1990. SATELLITE TELEMETRY DATA AND VHF RADIO TELEMETRY DATA The FWCC relied upon manatee telemetry data in evaluating manatee inhabitation for Brevard County. Included in the satellite and VHF radio telemetry data relative to inhabitation was a GIS database obtained from the "United States Geological Survey (USGS) Biological Resources Division, Florida Carribean Science Center, Sirenia Project, Gainesville, Florida," and reports authored by Dr. Charles Deutsch who analyzed the USGS data. The USGS Sirenia Project data analyzed by Dr. Deutsch were collected from May 1986 to May 1998, and included both VHF radio and telemetry and satellite telemetry data for the 78 manatees that were tagged for varying amounts of time during that period along the lower East Coast of the United States, excluding data for manatees that were born and raised in captivity. This data was considered by Dr. Deutsch as the best telemetry data available. Of the full USGS Sirenia Project data evaluated by Dr. Deutsch, 61 manatees were tracked at some time during the study period in Brevard County, including 16 manatees that were only tracked using VHF radio tracking and not satellite telemetry. The maximum number of tagged manatees observed in Brevard County during the study period was 12 manatees at one time. Dr. Deutsch opined that about one or two percent of the documented East Coast manatee sub-population was tracked each year. The radio telemetry data subsets from the Sirenia Project covered a ten-year period from May 1986, and included over 6,000 manatee observations for 54 individual tagged manatees. Of those 6,000 observation points, three-quarters (almost 5,000) were actual visual sighting of manatees made by persons on shore or in vessels. Of those visual sightings, approximately ten percent were made by non-government employees. The satellite telemetry data evaluated by Dr. Deutsch included data for 45-tagged manatees that was collected from April 1987 to May 1998, with over 34,000 location records of Class 1, 2, or 3 accuracy. Of the 61-tagged manatees that were observed in Brevard County during the 12-year study period, the median tracking period was 135 days, with some animals tracked for several years while others were tracked for shorter periods of time. Of the 61 manatees tracked in Brevard County, approximately one-half were fitted with radio or satellite telemetry transmitters (tags) while in Brevard County, the other half were tagged in different areas of northeast Florida, in southeast Georgia, or in southeast Florida. A majority of the animals tagged outside of Brevard County were observed in Brevard County, and Dr. Deutsch opined that this data demonstrated Brevard County to be the hub of manatee activity along the Atlantic Coast. MIGRATORY RANGE OF TAGGED MANATEES The size of the migratory ranges of tracked manatees varied with considerable variation of movement by individual manatees in Brevard County. Some manatees would spend eight months of the year near Canaveral Sewer Plant (Banana River) and spend each winter near Port Everglades (Ft. Lauderdale). Many tagged manatees displayed strong site-fidelity, returning to the same seasonal locations yearly while others did not. Telemetry data points are not precisely a depiction of the actual and true location of the manatee at the time of data transmission from the tag to the satellite. Services Argos, the company that administers the hardware, assigned 68 percent of the data points within 150 meters of the true location in class three locations. In 1994, USGS performed accuracy experiments in Brevard County of satellite telemetry and found location class 3 data points to be within 225 meters of the true location, and 95 percent within 500 meters of the true location. In addition to Dr. Deutsch's reports, FWCC considered various telemetry papers and publications pertaining to Brevard County: "Tagged Manatee Use of the Cocoa Beach/Thousand Island Area;" "Winter Movements and Use of Warm-water Refugia by Radio- tagged West Indian Manatees Along the Atlantic Coast of the United States;" and "Easton, Tagged Manatee Movement through the Canaveral Barge Canal, Brevard County Florida" (February 14, 1997). MANATEE SIGHTING DATA FWCC relied upon manatee sighting data in its evaluation of manatee inhabitation. Included in the sighting data was the Brevard County 2001 Rule Development and Trip Notes of February 6- 7, 2001; Sea Ray Boats, Inc. Water Test Re-Run Manatee Sighting Records for 2000-2001; Canaveral Barge Canal Boater Activity and Compliance Study; Sharon Tyson's Sykes Creek Observation Records; and cold-seasons sighting logs for the C-54 canal structure. STUDIES AND REPORTS PERTAINING TO MANATEE DISTRIBUTION, RELATIVE ABUNDANCE, HABITAT, BEHAVIOR, OR OTHER MANATEE INFORMATION. FWCC considered and relied upon the Brevard County Manatee Protection Plan that included an inventory and analysis section about manatees, analysis of manatee mortality data, manatee legislation and protection, law enforcement, habitat issues, existing boat facilities, Brevard County boating activity patterns, and an inventory of present manatee education programs. The existing Federal Manatee Recovery Plan, to which members of the Bureau of Protected Species and Florida Marine Research Institute contributed, was relied upon. SCAR CATALOG DATA FWCC considered and relied upon scar catalog data in evaluating manatee protection needs with Brevard County Misc. Information as the source provider. EXPERT OPINIONS FWCC relied upon expert opinions in evaluating manatee inhabitation. A staff meeting with manatee experts, as part of the process, included, but was not limited to, meetings with Jane Provancha and Sharon Tyson in December 2000, meetings and discussions with Dr. Charles Deutsch between November 2000 and May 2001, and various discussions with members of the federal Recovery Plan Team. OTHER AVAILABLE SITE-SPECIFIC INFORMATION FWCC considered site-specific information that was available, principally drafts of the Brevard County Manatee Protection Plan. FWCC also considered site-specific information about water skiing areas and prospective additional travel times in various waters proposed for new, or changed, regulations. DATA ANALYSIS Threat Analysis Rule 68C-22.001(3), Florida Administrative Code, contemplates a qualitative assessment and exercise of discretion by taking into consideration a balancing of manatee protection needs, including an assessment of relative threats to manatees, with the right of boaters, fishers and water skiers. In assessing where threats to manatees may exist from motorboats, the manatee death database provides information on confirmed interactions, such as locations where manatee carcasses have been recovered. Manatee deaths, carcass recovery and confirmed interactions locations are maintained in FMRI's database. From January 1974 to December 2000, 728 manatees died in Brevard County and 184 of those deaths were because of interactions with watercrafts. Watercraft related deaths account for 23.5 percent of all manatee deaths recorded in Brevard County between 1974 and 2000. Approximately 19 percent of all watercraft related deaths of manatees in Florida have occurred in Brevard County. FWCC has determined that manatee death from watercraft interaction is due to blunt trauma more than 50 percent of the time. Deaths from propeller cuts account for less than 50 percent. Often injury instead of immediate death from motorboat strikes is the case. Many manatees have scars from previous sub- lethal motorboat strikes, and manatees have been observed with more than 30 different strike patterns. Where the cause of death is classified as watercraft related, carcass recovery may or may not be where the collision occurred depending upon the acuteness of the injury at the time of collision. Acuteness of the injury, wind, current, tide, and decomposition all affect the location of the carcass at the time of salvage. Additionally, operation of motorboats can disrupt essential manatee behaviors such as warm water sheltering, feeding, sleeping, mating, and nursing. This harassment can lead to cold-related illnesses and increase mortality risk by driving manatees from warm water refuges. The increase in the Atlantic Coast manatee population and the increase of the number of boat registrations result in an increase in the threat of harmful collisions between boats and manatees. Geographic Scope of Threat Analysis Section 370.12(2)(m), Florida Statutes, does not specifically describe the geographic scope of the FWCC's evaluation of "other portions of state waters" for manatee sightings and assumed inhabitation on a periodic or continuous basis. Subsection 370.12(2)(g), Florida Statutes, suggests that the evaluation of manatee sightings is appropriate for large portions of navigable waterways, such as the Indian River between St. Lucie Inlet and Jupiter Inlet. A "waterway" is generally defined as "a navigable body of water." (Webster's Ninth New Collegiate Dictionary, p. 1333.) Rule 68C-22.001(3)(a)2.f., Florida Administrative Code, contemplates a qualitative assessment of the "likelihood of threat" to manatees. The only reference is to the "characteristics of the waterway in question." The rule does not mandate the geographic scope of a "threat evaluation." The FWCC analyzed various data on different scales depending upon the nature of the inquiry - the evaluation of sighting "frequency" generally considered a large geographical area such as a section of a river. Conversely, the regulatory alternatives to protect manatees were evaluated at a smaller or finer scale. The Commission also considered segments of waterways divided by causeways or natural barriers. The Commission considered research that divided Brevard County (north of Eau Gallie) into 12 zones for purposes of analysis. In the Brevard County Manatee Protection Plan, the waterways were analyzed in terms of seven "planning zones," to include review of physical characteristics such as bathymetry and sedimentological conditions, shoreline conditions, and water quality; Manatee Habitat Features, including sea grass, mangrove/salt marsh, freshwater sources, warm water refugia, calving and resting areas, feeding areas, travel corridors, and habitat protection; Manatee Data including manatee abundance and distribution and manatee mortality; boat facilities; boating activity patterns; waterspouts areas; and manatee zones. The Commission's consideration of waterway characteristics and manatee behavior during the Brevard County rule-making process, including the geographic scope of manatee inhabitation and threat from watercraft, was reasonable and consistent with the approach taken by other resource management agencies and researchers as contemplated by the statutory purpose. Proximity and Degree of Known Boating Activities FWCC evaluated available boating activity information in assessing threat. Staff considered the general analysis of boating activity and detailed analysis of boating activity in specific portions of Brevard County as provided in the County's MPP; included therein were maps that show locations of the County's 72 marinas and 65 boat ramps, of which 27 are public ramps. Also considered was the study of Brevard County-Wide Boating Activity by Dr. J. Morris, of the Morris of Florida Institute of Technology. Dr. Morris' inquiry resulted in the following specific finding. First, Brevard County residents are the primary ones who launch at boat ramps, followed by residents of Orange, Osecola, Seminole, Indian River and Volusia counties. Second, the Inter Costal Waterways experiences increases in transient traffic during late fall and winter months, including out-of-state boats. Third, Class One boats (16 to 25 feet) are the most observed type, followed by Class A (less than 16 feet) vessels. Fourth, most boating activity occurs during weekends. Fifth, the greatest concentrations of boats were in specific areas such as NASA causeway (SR 405, Indian River), East Canaveral Barge Canal, SR 520 and the Banana River (the Merritt Island Causeway), the Pineda Causeway (SR 404, Banana River), the Melbourne Causeway (Indian River), near Grant Island Farm, the Sebastian River and the Sebastian Inlet. Dr. Morris concluded that the boating public preferred to cruise the waters of the lagoons with the marked channels and use Indian and Banana Rivers as highways for recreational boating purposes. The United States Fish and Wildlife Service (USFWS) closed a portion of the northern Banana River within the Merritt Island National Wildlife Refuge to public boat entry, limiting public entry to wading or by non-motorized vessels. The closed area has one of the largest concentrations of manatees in the United States, and recently has been the most important springtime habitat for the east coast manatee population. As a result of the March 1990 closing to motorized boats, an average increase of manatee use observed during the summer months in the area increased by 60 percent. The increased use is attributed to improved habitat quality aided by the lack of human disturbance and reduced propeller scarring of sea grass. In December of 1994, Dr. Morris submitted a report, "An Investigation of Compliance to Boat Speed Regulations in Manatee Protection Zones in Brevard County, Florida." This report contained an analysis from on-water and aerial observations in both "slow speed" and "idle speed" zones in various areas of Brevard County for a one-year period of April 1993 to April 1994. At Mosquito Lagoon, of 1,214 boats observed, speeds were clocked for 98 percent of the boats and 11 percent of those exceeded the posted Inter Costal Waterways 30 MPH speed limit, all of which were recreational boats. At the Indian River site between Grant and Sebastian, 2,511 boats were observed, speeds were clocked for 97 percent of the boats and 16 percent of those exceeded the posted ICW 30 MPH speed limit. In posted "slow speed" zones outside the ICW channel, 25 percent of boats observed underway were deemed non- compliant with the speed zone limitation. Of those non-compliant Class A powerboats, the violators were typically personal watercrafts ("Jet Ski" type vessels.) A detailed boater activity study was made of the Canaveral Barge Canal and Sykes Creek Area. The study found, in part, that: highest boating use occurred during holidays, except during bad weather; most use occurred on weekends; and in Canaveral Barge Canal and Sykes Creek 63 percent of the vessels were Class 1 boats and 74.3 percent of the vessels were Class 2 or Class 3 boats. INCREASED LEVEL OF BOATING ACTIVITY IN BREVARD COUNTY In general, the level of boating activity in Brevard County continues to increase with the increasing population, launching facilities, and boat registrations in Brevard County and nearby counties, including Orange and Seminole counties. In 2000, 34,316 vessels were registered in Brevard County. In the preceding year there were 31,842 vessels registered. In 1995, 28,147 boats were registered and in 1987, 23,352 boats were registered in Brevard County. In 2000, Florida registered 840,684 recreational vessels, an increase over the 695,722 vessels registered in 1994. Boating accidents increased with the increased registration of vessels with Brevard County ranking 10th out of the state's 67 counties with the number of boating accidents. Brevard County, since mid-1990's, has registered an increased number of "flats skiffs" which are shallow draft, low profile motorboats capable of speeds up to 50-60 MPH while operating in shallow (about 1 foot) water and often used for sight-fishing in shallow sea grass flats. SEASONAL AND/OR YEAR-ROUND PATTERNS OF MANATEE USE AND THE NUMBER OF MANATEES KNOWN OR ASSUMED TO OCCUR IN, OR SEASONALLY USE THE AREA FWCC staff evaluated whether seasonal restrictions could or would be effective. Staff concluded that the only seasonal regulation of motorboats justifiable by the data was at the power plant discharges in the Indian River. At those locations, extreme concentrations of manatees are regular during the cold season. Year-round manatee protections were proposed for this area, but they would have to be more restrictive during the winter months. During the coldest periods of winter, following a strong cold front, manatees have been observed in large concentrations in: the power plant discharges at Florida Power and Light Company's Indian River plant and at the adjacent Reliant Energy Plant and the Sebastian River Canal. The congregation of manatees at thermal refuges on cold winter days was not for the duration of the winter season. They have been known to leave the thermal refuge for a part of a day, a day, or for many days at a time. Sharon Tyson, observer, performed a detailed Brevard County Manatee Photo-Identification Project during late 1999 and early 2000 at the Brevard County power plants, and documented a number of manatees in the FPL discharge zone between December 24, 1999, and March 4, 2000. During that period the number of manatees in the zone varied greatly, through late-December to mid-January (from 7 to 57 manatees). On January 16, 2000, no manatees were present. On January 17, 2000, 10 manatees were present. On January 23, 2000, 29 manatees were counted. Two weeks later, February 6, 2000, 111 manatees were present. Similar sightings made at the C-54 Canal Structure (near Sebastian Creek), during the same time-period, found as few as 11 manatees to as many as 90 manatees. Apart from the extreme concentration of manatees during extremely cold periods, manatees are distributed through the county waterways during each season of the year. The 1997-1999 Brevard County Aerial Survey GIS Plots gave a clear representation of year-round manatee distribution patterns varying greatly. MANATEE MORTALITY TRENDS WITHIN THE AREA Only in rare cases is the approximate or actual location of a manatee and motorboat collision known. The FWCC considered and relied upon a review of the general trend of watercraft-related (and other) mortality County-wide to assess a generalized increased mortality trend. In doing so as part of the rule-making process, FWCC reviewed total manatee mortality for Brevard County for the period for which records existed from 1974 to 2000. That data base source indicated increasing watercraft mortality in recent years. FWCC evaluated manatee salvage data for January-March 2001 and preliminary information for April-May 2001. Staff employee, Scott Calleson's working file mortality information was reviewed and considered as was Dr. Ackerman's "Mortality Rates White Paper," which concluded that human-caused manatee mortality levels were at an unsustainable rate in the Atlantic, Brevard County, Tampa Bay, and Southwest Florida Regions. The Florida Inland Navigation District provided documentation that was considered in the FWCC rule making that included a regional evaluation of "Watercraft Related Manatee Deaths in the Nine Critical Counties of FIND" from 1990-1999. Of these nine critical east coast counties, Brevard County had the highest mortality trend. During the last two-to-three years, there has not been a clear trend of increased manatee mortality in Brevard County, but the number of watercraft-related mortalities is capable of being reduced, in part, through improved regulations. Historical manatee mortality data for Brevard County from 1977 through 2000 demonstrates a clearly increasing trend in watercraft-related manatee mortality. For each five-year increment, water-related manatee mortality has increased as follows: from 1977-1979 there were an average of 1.9 water-related mortalities/year; 1980-1985 there were 4.6 mortalities/year; 1986-1990 there were 7 mortalities/year; 1991-1995 there were 8.8 mortalities/year; and 1996-2000 there were 11.8 mortalities/year. EXISTENCE OF FEATURES WITHIN THE AREA THAT ARE ESSENTIAL TO THE SURVIVAL OF, OR KNOWN TO ATTRACT, MANATEES SUCH AS SEAGRASSES, FAVORABLE WATER DEPTHS, AND FRESH OR WARM WATER SOURCES Dr. Deutsch stated that his telemetry analysis indicated that the most important habitat correlation for Brevard County manatees was with sea grass, and in particular, often with outer edge of sea grass beds. Manatees prefer feeding on submerged, emergent and floating vegetation, generally in that order. Manatees extensively use Brevard County sea grass beds for feeding. Sea grass coverage is depicted on the Florida Department of Environmental Protection's Boater's Guide to Brevard County, which has no date, but was prepared by the DEP. Sea grass coverage in 1989 is depicted in the 2000 maps prepared by the STMC, using the Atlas of Marine Resources, Versions 1.2 and 1.3b. The most recent St. Johns River Water Management District sea grass coverage data for the Indian River Lagoon indicates a strong correlation between sea grass coverage in waters with an average depth of 66.93 inches (1.7 meters) or less. As of 1992, of the estimated 46.190 acres of sea grass in Brevard County, nine percent of the sea grass suffered light scarring from boat activity; 4.2 percent of the sea grass suffered moderate scarring; and 13.4 percent of the sea grass suffered severe scarring. Areas with boat scarring of sea grass included a number of areas that are included within proposed "slow speed" zones: the eastern portion of Turnbill Basin; the eastern shoreline of the Indian River between the NASA railroad bridge and Rinkers Canal; the Banana River around Manatee Cove and south of the City Golf Course; the northwest part of Newfound Harbor; and the western shoreline of the Banana River, between Newfound Harbor and Pineda Causeway. The location of the proposed manatee protection zones corresponds well to the location of sea grass beds, deeper waters and channels adjacent to sea grass beds or established migratory routes, and fresh warm water sources. FAVORABLE WATER DEPTHS Dr. Deutsch stated that his telemetry analysis indicated that bathymetry is an important habitat correlate for Brevard County. Generally, tagged manatees were observed in the area from a two-meter (6.65 feet) depth contour to the shoreline. FWCC consideration of "favorable water depths" took into account the fact that water levels fluctuate in the Indian River Lagoon. However, unlike many coastal areas of Florida, the Indian River Lagoon does not experience significant daily tidal fluctuation. On an annual basis, however, the water level fluctuates about 2.5 to 3 feet in response to environmental conditions. It was determined to be impractical to amend manatee protection rules (and to move regulatory signs implementing the rules) in response to changing water levels. Manatees usually swim between one to three meters (3.28 to 9.84 feet) below the surface, surfacing every few minutes to breathe, and typically feed at just below the surface to a depth of three meters. Manatee experts, including persons with extensive experience observing manatee behavior in Brevard County, all testified that manatees used areas where the water level at the time was less than three feet for mating, feeding, fleeing a pack of male manatees, and resting. The FWCC used a bathymetric survey prepared on behalf of the St. Johns River Water Management District for purposes of establishing preferred sea grass habitats during the rule-making and considered the bathymetry in conjunction with other data to predict areas where manatees are likely to inhabit. The St. Johns District advised the FWCC staff that the 1.7-meter depth on its bathymetric survey was the rough depth limit for sea grass, and provided the FWCC staff with a GIS file on the bathymetric survey at 0.3-meter depth intervals for most areas, although the approximate sea grass contour was shown as 1.5 to 1.7 meters. Surveys are tied to a horizontal datum and a vertical datum. A survey depicts the three-dimensional lagoon basin, part of the spheroid planet Earth, on a two-dimensional map. The hydrographic survey data used by the FWCC in the rule-making was based upon a survey tied to a horizontal datum - North American Datum (NAD) 83/90; and a vertical datum - North American Vertical Datum of 1988 (NAVD-88). The horizontal and vertical accuracy of the survey differs. Positional accuracy of horizontal (e.g. shorelines) points is within 1 to 5 meters (3.28 to 16.4 feet). Vertical accuracy of depth data points averages within .03 feet. The hydrographic survey states that it is not to be used for navigation - - "The use of NAVD-88 for the bathymetric survey gives the impression of deeper water than is actually present within the lagoon since the "0" contour of NAVD-88 is located on dry land approximately 1 foot above the ordinary water line." Manatee distribution from aerial surveys and 1992 bathymetry data was graphically depicted by the STMC and confirms manatee use of areas proposed for regulation in the proposed rules. FRESH WATER SOURCES FWCC considered and relied upon major fresh water sources that have been historically used by manatees such as: Turnbull Creek; Titusville Marina/POTW; Addison Canal; the two Indian River power plants; two wells along the eastern shoreline of the Indian River approximately two miles south of Rinkers Canal; the intersection of Bacardi and Dakar Drive in Sykes Creek; the Cape Canaveral POTW (sewer plant); the Banana River Marina; the outfall into the Indian River from the east shore of Merritt Island westerly of the south end of Newfound Harbor; the Indian River Isles; the Eau Gallie River; Crane Creek; Turkey Creek; and the Sebastian River. Also considered were less significant sources of fresh water found at many marina basins, at the Sear Ray Boats, Inc. facilities and in residential canals. WARM WATER SOURCES FWCC considered major warm water sources in the two Indian River power plants and the Sebastian River Canal. Minor sources of warm water include deeper water and areas with artesian springs such as: Port Canaveral; a basin off Wynar Street in Sykes Creek; the Banana River Marina; and the Berkeley Canals. CHARACTERISTICS OF THE WATERWAY IN QUESTION IN RELATION TO KNOWN BOATING ACTIVITY PATTERNS FWCC considered, as its basic source document, Morris' Final Report for Brevard County Boating Activity Study. Boating activity patterns in Brevard County are dependent upon weather, economic conditions, and other factors. Larger motorboats (including tug/barge combinations) are constrained in movement to deeper water--in some areas, primarily within marked or maintained navigation channels including the Canaveral Locks, Canaveral Barge Canal, ICW, and Banana River main channel. In the Indian River, south of the NASA railroad bridge, the deeper area outside of the marked channel widens to between half-a-mile to a mile with depths ranging from seven to 12 feet MLLW, all the way to Rock Point, just north of Grant. For most of the length of the County, larger boats have sufficient water depth to travel adjacent to the ICW channel. Waters outside the main channel in the Banana River are relatively shallow. The Canaveral Barge Canal is dredged to maintain a depth of approximately 15 feet. Barges and escorting tugs navigate through the Canaveral Locks and into the ICW. Some barges proceed northward from the Canaveral Locks into the Banana River channel to make deliveries to the Space Center, according to the Lockmaster, Mr. Querry. Sea Ray Boats, Inc.'s, design and production facilities located along the Canaveral Barge Canal use the Canal to access testing areas to the west in the Indian River ICW, to the east in the Banana River channel, and in the Atlantic Ocean. Limited retests are permitted in an area adjacent to the Canaveral Barge Canal facilities. Recreational motorboats and personal watercrafts can be operated outside of marked channels. Some of these recreational motorboats can navigate "on plane" and up to 60 MPH in water about one-foot deep. Motorboat users engage in a variety of activities having differing operational patterns. Fishers might prefer to travel at relatively high speed enroute to preferred fishing areas, and then operate with a push pole, trolling motor or adrift, in order to hunt certain species of fish. If no fish are located, then high-speed operation to another spot is used, repeating the pattern of locating fish by sight. Water-skiers usually operate at high speed in a relatively small area, usually protected from the wind, and often located near an island or park. BOAT-MANATEE INTERACTIONS FWCC considered that manatees display varying reactions to motorboats. Higher speed motorboat operation in relatively shallow water presents a greater threat to manatees than operation at slow speed or idle speed or than operation in relatively deeper waters, since manatees have fewer opportunities to avoid the collision. Manatees can swim or rest at the surface or underwater and must come to the surface to breathe air every two to three minutes for smaller, active manatees and up to 20 minutes for large, resting manatees. Their general cruising speed is two to six miles per hour, but they can travel at short bursts up to 15 MPH. Boats operated at "slow speed" vary in miles-per-hour over the bottom within a range of about seven to eight miles-per- hour. At "slow speed," the manatee and vessel operator have more time to avoid collision, or the manatee can avoid serious blunt trauma injury from collisions with most vessels. The ability of manatees to avoid being hit by motorboats has diminished in Brevard County as a result of an increase in the manatee population, increase of motorboats, increase in boating access points, and development and use of faster boats that operate in less-predicable (non-linear) patterns in relatively shallow waters where manatees often feed on submerged vegetation. TESTIMONY REGARDING MOTORBOAT-MANATEE INTERACTION Officer Dennis Harrah, qualified as expert in boating safety, marine law enforcement, and local knowledge of the waterways of Brevard County, testified that "slow speed" zones provide greater reaction time for the vessel operator to avoid collision than unrestricted speed areas and than the "25 MPH maximum speed" areas. He further testified that "idle speed" zones provide greater reaction time for vessel operators to avoid collision than "slow speed" areas. Dr. John Reynolds, qualified as expert in marine mammal conservation and policy, manatee biology and behavioral ecology of marine mammals, opined, based on frequent observation of motorboat-manatee interactions, review of videotapes of such interactions, and review of studies on the subject, that there is an increased threat to manatees associated with boats that operate in planing speeds as opposed to slow speeds. His opinion is based, in part, on "common sense" that objects moving faster have greater momentum and therefore greater magnitude of impact, and on the reduced reaction time of both vessel operators and manatees to avoid collision. Dr. Reynolds was not aware of any evidence to suggest that the majority of watercraft strikes to manatees are from vessels operating at "slow speed," and it is his belief that "a good percentage of manatee mortality was from fast-moving vessels." Ms. Spellman, qualified as expert in marine biology and in manatee rescue and salvage, testified that she had observed considerable variability in manatees' reactions to kayaks, canoes and windsurfers, including manatees approaching the vessel, manatees not reacting at all, and manatees swimming away. She has observed manatee reactions to small motorboats as highly variant, depending upon the animal, including: swimming under a slow-moving motorboat, moving just as a motorboat approaches at idle speed, or diving and leaving the area as soon as a motorboat got anywhere near. Ms. Spellman testified, based upon her presence in the waters of the Canaveral Barge Canal or in the Port east of the Locks, that she has been in the water with manatees on five occasions when a barge/tug combination came by and in all cases the manatees reacted to the barge well in advance of the barge coming near her and the manatee, and that in each instance the manatee swam to within 15 to 20 feet of the shoreline. Of the thousands of times that she has seen manatees, she estimated that 95 percent of the time the manatees had scars from boat propellers or skegs. Dr. Powell testified, based upon over 30 years of observation of boat-manatee interactions, that the typical reaction is a flight or startle response, often to dive to deeper water. The diving response may take the manatee under the boat, away from the boat, or across the path of the boat. Based on his observations, including manatees reacting to motorboats moving at "idle-speed," "slow-speed" and at "faster-speeds," Dr. Powell opined that the manatees' reactions resulted from acoustical cues, visual cues, and perhaps pressure cues. Captain Singley, tugboat operator in Brevard County for over 30 years, observed a group of manatees react to a fast moving planing hull; some animals broke the surface, others scattered to the right or left, and others dove to the bottom. Mr. Walden, Sea Ray's Boat, Inc.'s, performance and water test specialist, testified that he had observed manatees in the Barge Canal, and sometimes the manatees would react to the motorboat. The majority of time when the boat was operating at planing speed or faster the manatee would dive and go deeper, and would began evasive action, upon hearing and noticing the motorboat a couple of hundred feet away. Dr. Gerstein testified that fast moving boats can hit manatees and that he was not aware of any physical evidence, eye- witness account, or law enforcement report of a slow-moving boat hitting a manatee. STUDIES ABOUT MOTORBOAT-MANATEE INTERACTION KNOWN BOAT STRIKES FWCC considered that watercraft collisions with manatees are rarely reported to authorities, and, as a result, it is difficult to directly assess the circumstances of such collisions, such as boat size, type and speed at the time of collision. A summary entitled "Watercraft-related Manatee Deaths Where the Responsible Vessel is Known," indicates that barges, displacement hull vessels, and planing hull vessels are known to have been in fatal collisions with manatees. In those planing- hull incidents where the vessels and estimated speed are known, the speed of the vessel ranged from getting-up-on-plane (45-foot boat with twin 425 HP outboard motors) to 35 MPH (18-foot boat with 150 outboard motor). Two other incidents were a 46-foot boat with twin inboard motors operating at 18 knots and a 20- foot boat with 200 HP outboard operating at 20 MPH. The only indication that a slow-moving planing-hull vessel struck a manatee is a report from an individual who was operating at estimated five MPH in a flat hull vessel and reported to have "felt a bump on aft hull, saw two animals (manatees) swam off." PROTECTION OF MANATEE-SEA GRASS HABITAT FWCC considered protection of sea grass habitat a secondary purpose in the Proposed Rule for areas subject to Section 370.12(2)(m), Florida Statutes. The Florida Guide To Recreational Boating notes that: Sea grass beds have been severely scarred (torn up) by boats operated in extremely shallow water. This is due, in part, to the "flats fishing craze" and the rising popularity of vessels designed to operate in shallow water. The Guide recommends that operators set the boat's drive unit at the highest possible setting and that the operator "proceed at idle speed when moving through shallow grass beds." Dr. Reynolds testified that "idle speed" or "slow speed" shoreline buffer zones provide greater sea grass protection (and manatee conservation) than higher motorboat speeds. The Executive Director of the Indian River Guides Association testified that the group is promoting "pole and troll" areas within the Merritt Island National Wildlife refuge portions of the Indian River Lagoon. He stated that many people from Orlando and elsewhere bring their boats by trailers to Brevard County, or move to Brevard County, and operate their boats so as to tear up seagrass beds. FWCC correctly concluded that "slow speed" and "idle speed" zones provide a greater measure of protection to shallow seagrass beds than do higher speeds for motorboats. DATA SOURCES CONSIDERED BY FWCC IN PROMULGATING THE PROPOSED RULE Differing Opinions About Manatee Protection Areas FWCC's Opinion The FWCC, based on the following, took the position that the proposed rules are more likely to protect manatees from motorboat impacts than the existing rules, and that the proposed rules take advantage of the available science of manatee biology and conservation, using the same basic approach used in manatee conservation by officials in Australia to protect dugongs (another Sirenian) from motorboats. The FWCC postulates that "idle speed" and "slow speed" zones provide greater protection to manatees than do higher motorboat speeds. "Maximum 25 MPH" speed zones in deeper water areas provide greater manatee protection than do unregulated waters. Most motorboats observed operating in unregulated areas (outside "slow speed" or "idle speed" zones) in Brevard County, during Dr. Morris' boating compliance study, were operating at or below 25 MPH. The FWCC correctly concludes that "maximum 25 MPH" speed was reasonable in light of research into the minimum planing speed of most recreational motorboat models, the observations of typical motorboat speed and operation in unregulated waters of Brevard County. The FWCC considered 1997 DEP-solicited information from motorboat manufacturers to determine minimum planing speeds and maximum planing speeds, and draft on- and off-plane for various sizes and types of motorboats. Considered also by the FWCC was boating test literature to determine that most boat models could reach planing speed at or slightly below 25 MPH. The FWCC considered information that was submitted showing that many production boats reached planing speed between 20-25 MPH. For example, Scout Boats' 11 models planed between 20- 25 MPH, and Shamrock's 13 models planed between 20-25 MPH. The Florida Marine Research Institute's 1992 information on this topic found a range of minimum planing speed between 14 and 24 MPH. Motorboats operating at speeds higher than 25 MPH are many. Ranger Boats offered several models with maximum speed in the "upper 60's" to "low 70's"; Scout Boats' models had top speeds of 35-60 MPH; Shamrock's models ran at the top end between 36-41 MPH; Donzi Boats operate at speeds in the 70 MPH range; and Bayliner's Capri 1700LS had a top speed of 46 MPH, as did Stingray's 180RS. Since the FWCC's creation, speed zone rules adopted for Lee County included maximum 25 MPH zones. Rule 68C-22.005, Florida Administrative Code for Brevard County has regulated motorboats with a "maximum 25 MPH" speed in channels. Commission staff applied their professional judgment in developing recommendations on manatee protection areas, and presented those recommendations to the FWCC, who considered staff recommendation, in context with public comment, to determine what manatee protections were warranted. PETITIONERS' OPINIONS The various Petitioners advocate manatee protection zones that, in many cases, are similar to the FWCC's proposed rules, including "slow speed" shoreline buffer zones and "maximum 25 MPH channels." Petitioners' challenge to many of the protection zones alleges that FWCC's basic regulatory mechanisms are flawed. FEDERAL LAWSUIT-SETTLEMENT AGREEMENT On or about January 13, 2000, STMC and other related environmental groups filed a lawsuit in the Federal District Court against Alan Egbert as Executive Director of the FWCC. The suit alleged, inter alia, that the FWCC is in violation of the Endangered Species Act by permitting the unauthorized taking of manatees in the State of Florida. During the pendency of the litigation, FWCC engaged in a series of mediations resulting in a settlement agreement approved by FWCC and executed by the parties in April 2001. The agreement contained a series of maps with draft manatee (speed) zones for Brevard County. Petitioners alleged that "the genesis of the Proposed Rule is this settlement agreement reached in the Egbert case, and there is a definite connection between the language of the Proposed Rule being challenged and the settlement agreement." Petitioners' speculative conclusion regarding this suit was tendered without one iota of evidence. Mr. Calleson, FWCC's staff employee, acknowledged that portions of existing speed zones and proposed speed zones in maps resulting from the federal mediation process contained a "lot of similarities" with speed zones in maps of the proposed rule. Mr. Calleson acknowledged that the FWCC did not direct staff to conduct negotiated rule-making on the proposed rule, and staff participation in the federal mediation process was not a negotiated rule-making process pursuant to Section 120.54(2), Florida Statutes, which provides, in pertinent part: (d)1. An agency may use negotiated rulemaking in developing and adopting rules. The agency should consider the use of negotiated rulemaking when complex rules are being drafted or strong opposition to the rules is anticipated. The agency should consider, but is not limited to considering, whether a balanced committee of interested persons who will negotiate in good faith can be assembled, whether the agency is willing to support the work of the negotiating committee, and whether the agency can use the group consensus as the basis for its proposed rule. Negotiated rulemaking uses a committee of designated representatives to draft a mutually acceptable proposed rule. * * * 3. The agency's decision to use negotiated rulemaking, its selection of the representative groups, and approval or denial of an application to participate in the negotiated rulemaking process are not agency action. Nothing in this subparagraph is intended to affect the rights of an affected person to challenge a proposed rule developed under this paragraph in accordance with s. 120.56(2). THOMAS MCGILL PETITIONERS Most of the McGill Petitioners support the adoption of rules that are consistent with the Citizens for Florida Waterway, Inc. (CFW), proposal submitted on December 29, 2000. The CFW proposal endorsed the use of "slow speed" zones, the use of "maximum 25 MPH zones," existing power plants "idle speed" and "motorboat prohibited" zones, and the use of shoreline buffers. The CFW proposal differed from the proposed rules primarily in scope of the proposed zones, rather than the nature of the proposed zones. The CFW proposal recommended numerous 25 MPH channels (in marked channels) through protected areas: from the Canaveral Locks through the Canaveral Barge Canal to the Indian River (except for three slow-speed boating safety zones); in North Sykes Creek; in the Banana River north of State Road 528 and between Bicentennial Park to the State Road 520 Relief Bridge. STANDING WATCH, INC. Stowell Robertson, one co-Petitioner of Standing Watch, Inc., is Executive Director of the Indian River Guides Association, Inc. (Guides). Mr. Robertson wrote the Guides' Recommendations, but his personal recommendation differed in two respects: in the North Indian River between NASA railroad bridge and the State Road 405 bridge, he would establish a "slow speed" zone from the western shoreline out to 500 feet (instead of 300); and he would impose a maximum 25 MPH speed in the Canaveral Barge Canal instead of 20 MPH. The Guides recommended that motorboat speed and operation be limited as follow: Mosquito Lagoon-make no changes to existing rule Turnbull Basin, North Indian River Create two "slow speed" zones in Turnbull - one in the Mimms Scottsmoor Canal, another from Jones Road boat ramp to Little Flounder Creek from the shore to 100 feet into the Basin; Set a new "slow speed" zone on the north side of the NASA railroad causeway and bridge out to 250 feet; Set a maximum 25 MPH in the ICW from Haulover Canal to the NASA railroad bridge; Take no further action [to change regulations]. Indian River, NASA railroad bridge to S.R. 402 Place "slow speed" zones on the south side of the NASA railroad bridge and causeway out to 250 feet; Reduce the [existing] west shoreline "slow speed" zone so that the western boundary is 350 feet from the ICW between markers R2 and G1; Set a maximum 25 MPH in the ICW; Take no further action [to change regulations] Indian River, State Road 406 to State Road 402 (1) and (2) Replace eastern "slow speed" zone with reduced "slow speed" zone extending from Peacock's Pocket to the existing "slow speed zone north of the State Road 405 Causeway, extending from shore to 250 feet west of the sand bar/drop off or three feet of water; Reduce the size of the "slow speed" zone north of State Road 405 Causeway to 300 feet; Reduce the size of the existing western shoreline "slow speed" zone to 500 feet from shoreline; Take no further action [to change regulations]. Indian River, State Road 405 to State Road 528 Bridge Close the warm water refuge sites at the power plants to manatees, not to boats; Deliver fuel to the power plants by land; Reduce the existing "slow speed" zone on the western shoreline to 1,000 feet from the shore; Take no further action [to change regulations]. Canaveral Barge (and Banana River to Locks) Maximum 20 MPH channel from Indian River to entrance to Canaveral Locks with "slow speed" zones at 100 feet either side of State Road 3 bridge, Sea Ray docks, Harbor Square Marina; Take no further action (to change regulations). Banana River (1) (2) All waters of Banana River, including channels, not otherwise regulated at "slow speed" should have 25 MPH limit; Reduce all existing "slow speed" zones along east and west shorelines, causeways, and bridges to 500 feet of shore; Retain existing "slow speed" zones in the two channels into "Long Point"[north and south ends of Canaveral Sewer Plant area]; Take no further actions [to change regulations]. Newfound Harbor (1) (2) All waters of Newfound Harbor, including channels, not otherwise regulated at "slow speed" should have a 25 PMH daytime limit and 20 MPH nighttime limit; Establish a "slow speed" zone along western shoreline from State Road 520 south to Two Islands; Establish a "slow speed" zone along eastern shoreline from State Road 520 south to the inside point north of Buck Point; The east and west "slow speed" zones be 500 feet from shorelines, and 200 feet[along northern shore] from S.R. 520; Take no further action. Sykes Creek North State Road 520 Set speed limit in marked channel at 20 MPH; All residential canals should be "slow speed"; Take no further action. Indian River State Road 528 to State Road 520 Establish 500 foot "slow speed" zones along western and eastern shorelines and 200 feet from causeways and bridges; Take no further action. Indian River State Road 520 to State Road 404 Establish 500 foot "slow speed" zones along western and eastern shorelines and 200 feet from causeway bridges; Take no further action. Indian River State Road 404 to State Road 518 Establish 500 foot "slow speed" zones along western and eastern shorelines and 200 feet from causeways and bridges; Take no further action. Indian River State Road 518 to State Road 192 Establish 500 foot "slow speed" zones along western and eastern shorelines and 200 feet from causeways and bridges; Establish Eau Gallie River "slow speed" zone with 20 MPH speed limit in marked channel daytime only, "slow speed" at night; Take no further action. Indian River (1) Establish 500 foot "slow speed" zones along western and eastern shorelines and 200 feet from causeways and bridges; (2)-(5) Crane Creek, Turkey Creek, St. Sebastian River, C-54 canal should be "slow speed"; Take no further action. Mr. James Kalvin, Standing Watch co-Petitioner and also President of Standing Watch, Inc., testified at deposition that neither he, nor the corporation, had any objection to the existing Brevard County manatee protection rules. SPECIFIC PROPOSED ZONES CHALLENGED The Petitioners' Challenge All Petitioners challenged the validity of Proposed Rule 68C-22.006, as "an invalid exercise of delegated legislative authority" as that phrase is defined in Section 120.52(8), Florida Statutes. MCGILL PETITIONERS The McGill Petitioners challenged the proposed rule amendment for Brevard County manatee protection areas, Proposed Rule 68C-22.006 (2)(d)2, 5, 6, 7, 8, 11, 12, 13, 14, 15, 16, 17, and 18, as an invalid exercise of delegated legislative authority. They allege that additional slow speed zones in Brevard County are invalid because the FWCC exceeded the authority granted in Section 370.12(2), Florida Statutes. McGill Petitioners based their allegations on the FWCC's lack of definable principles or data and an erroneously assumed cause-effect relationship for boat-manatee collisions, failure by the FWCC to consider the hearing limitations and capabilities of manatees in their environment, and a failure by the FWCC to employ standards and definitions for critical terms in its rule promulgation. At the final hearing, McGill Petitioners agreed that they do not object to that portion of Proposed Rule 68C- 22.006(2)(d)15 that reduces the width of the slow-speed zone in the Banana River between State Road 528 and State Road 520 causeways. Petitioners do, in fact, object to removal of the 25 MPH exemption for residential channels. The McGill Petitioners' position as set forth in their Prehearing Stipulation states: The Florida Fish and Wildlife Commission has exercised unbridled discretion and acted beyond the authority delegated in 370.12(2)(m), Florida Statutes, and has developed the proposed rule in an arbitrary and capricious manner. The proposed rule exceeds the delegated legislative authority because it is not based on scientifically definable principles or data. By failing to understand the root cause of watercraft mortality such as the manatee's inability to hear slow moving vessels, the Commission cannot deem their actions "necessary" to justify imposing speed restrictions as required by Section 370.12(2)(m), Florida Statutes. The Commission continues to impose speed motorboat restrictions even after finding that such restrictions are ineffective at preventing manatee mortality. The Commission relies on a flawed mortality database, a poor understanding of the limitations and applicability of satellite telemetry data, and lack of standards and definitions for critical terms. [emphasis added] The McGill Petitioners' Amended Petition alleged in paragraph 6: The Commission has not employed the best available science or even reasonable science. . . . aerial survey and telemetry data were misapplied. . . . in that areas that did not reflect frequent usage . . . were designated . . . slow speed zones. Also, the use of inaccurate telemetry tracking information was used as the basis for justifying areas where aerial survey data showed no manatee activity. . . . In support of their alleged inaccuracy of the satellite telemetry data, Petitioners presented the testimony of Mr. Dvorak and his Power-point Presentation of Aerial Survey Mortality, Telemetry and Bathymetry Assessment, and other technical papers. Mr. Dvorak did not include in his presentation/analysis survey data available on the Atlas or Marine Resources and did not include all telemetry data available from the United States Geological Survey, which was included in Dr. Deutsch's analysis presented for Respondent, FWCC. The Amended McGill Petition, paragraphs 10 and 12, stated: The McGill Petitioners advised the FWCC that creation of new "slow speed" zones was based upon incorrect assumption "that such slow speed zones alleviate collisions between vessels and manatee" and they suggested that "slow moving vessels are responsible for the majority of documented manatee collisions." McGill Petitioners' evidence proffered to demonstrate that "slow moving vessels are responsible for the majority of documented manatee collisions," consisted of inclusive studies and undocumented theories to demonstrate that slow speed zones do not alleviate collisions between vessels and manatees. FWCC considered an abundance of the best evidence of known or suspected collisions between vessels and manatees that demonstrated that "fast moving motorboats" are a known major source of manatee- vessel collisions. The McGill Petitioners further stated in paragraph 11 that: The rule does not consider the acoustic realities of the manatee's hearing limitations and its environment. McGill Petitioners presented the testimony of Dr. Edmund Gerstein regarding his measurements of the manatees' ability to hear noises. Dr. Gerstein concluded from his research that manatees have difficulty hearing and locating low-frequency sounds (below 400Hz), and they have difficulty detecting sounds of any frequency when it is not sufficiently louder than the ambient noise level. The testimony of Dr. Joseph Blue was given in support of the McGill Petitioners' position that low-frequency sounds are quickly attenuated in shallow water because of the Lloyd Mirror effect. Upon this foundation, Dr. Blue testified that since sound is shadowed ahead of the barge(s), the tugs that push the fuel oil barges between Prot Canaveral and the power plants on the Indian River emit low-frequency sound that is shadowed in the forward direction by the barge(s) and it would be undetectable to animals. Thus, the McGill Petitioners' witnesses concluded that there are acoustic consequences associated with slowing down boats. According to Dr. Gerstein, requiring motor boats to travel a slow speed deprives manatees of acoustic information they can use to detect, localize, and avoid boats. It is this "science of acoustics" Petitioners alleged that the FWCC gave no weight in promulgating the proposed rule. The FWCC considered the issues raised by acoustic studies. The FWCC's Executive Director was advised on the subject by the Manatee Technical Advisory Committee (MATC) whose recommendation resulted from a workshop on acoustic research and technology with presentations of the work of Drs. Gerstein and Blue. No reliable scientific sources, professional literature, expert opinions, and direct observations of manatee reactions to motorboats, supports the proposition of Drs. Gerstein and Blue that manatees cannot hear slow-moving motorboats. The FWCC rejected the studies of Drs. Gerstein and Blue. McGill Petitioners' alleged in paragraphs 3, 4, 13, and 14, of their Amended Petition that the FWCC did not provide a reasonable opportunity for and ignored much of the public's input. In their Prehearing Stipulation, the McGill Petitioners' acknowledgement of public hearings held by FWCC and the opportunity for pubic input during those hearings. There is an abundance of evidence in the record that demonstrates that the FWCC staff held non-mandatory pre-rule development meetings with interested persons, including some of the McGill Petitioners. The Staff held two rule development workshops in Brevard County. Staff held a public hearing specifically on the Proposed Rules in Brevard County. Staff considered the rule adoption at many hours of public hearings on three different dates and locations. Staff mailed special notices regarding the Proposed Rules to all identified waterfront property owners of whom many are the McGill Petitioners, and Staff mailed a series of survey documents to identified boaters and businesses in conjunction with the preparation of a statement of estimated regulatory cost. (CSERC) In paragraphs 7 and 9 of their Amended Petition, the McGill Petitioners alleged that the FWCC entered into a Negotiated Rule-Making Process with litigants to the exclusion of a balanced committee in violation of 120.54(2)(d)1., Florida Statutes. Section 120.54(2)(a), Florida Statutes, authorizes an agency to engage in development of a "preliminary text" or "preliminary draft" of proposed rules prior to the publication of a notice of rule development. Preliminary maps of amendments to the BCMPR were similar to maps being discussed as part of the federal mediation. This fact alone is not a basis to conclude violation of the above-cited statutes. A second rule development workshop was noticed to discuss a preliminary copy of the Staff's "zone configuration" being considered. Subsequent to the second workshop, the FWCC authorized publication of Notice of Proposed Rule-making that incorporated changes to the preliminary draft maps that were discussed at the workshop. The McGill Petitioners, during the hearing, agreed that they do not object to that portion of Proposed Rule 68C-22.006(2)(d)15 that reduces the width of the slow-speed zone in the Banana River between State Road 528 and State Road 520 causeways. Petitioners do, in fact, object to removal of the 25 MPH exemption for residential channels. Petitioners offered no testimony in support of this allegation, choosing rather to adopt the evidence and position proffered by Standing Watch, Inc., herein below addressed. In paragraphs 5 and 15 of their Amended Petition, the McGill Petitioners alleged that the Commission did not properly address the consideration of lower cost regulatory alternatives. The "lower cost regulatory alternatives" submitted by McGill, Pritchard and Dvorak were considered and were discussed in the draft SERC. The draft SERC gave reasons for the rejection of each of the proposed "lower cost regulator alternatives," primarily because none would substantially accomplish the objectives of the law being implemented. The SERC was finalized, as required by Sections 120.541(1)(a) and (c); and 120.56(2)(b), Florida Statutes, before filing for adoption with the Secretary of State. In paragraph 17 of their Amended Petition, the McGill Petitioners alleged that the FWCC failed to employ metrics or standards that could be used to validate the effectiveness of both proposed and existing rules, in rule promulgation, and that without the use of metrics, the FWCC had no way to determine and verify that speed zones they propose are necessary to protect harmful collisions with motorboats. The McGill Petitioners proffered no evidence of specific "metrics or standards" that would validate the effectiveness of the existing and or the proposed rule they contend the FWCC could have or should have used in the Proposed Rule development. The FWCC relied upon the best available and reliable information in its rule-making, including opinions of experts. To the information available to it, the FWCC applied its professional judgment, gave consideration to public comments/concerns provided during public meetings, and considered the estimated regulatory costs and other applicable rule-making requirements. In paragraph 18 of their Amended Petition, the McGill Petitioners alleged that the FWCC repeatedly ignored requests to sub classify watercraft-related mortalities in order to properly identify appropriate corrective action. The FWCC considered all available data regarding manatee injury and death resulting from the speed of motor boats and rejected Petitioner's contention that boat size, large boats such as tugs and barges, were more dangerous to manatees than smaller and faster motorboats. Sea Ray Boat, Inc. Petitioner, Sea Ray Boats, Inc., challenged only Proposed Rule 68C-22.006(2)(d)(11) that modifies the existing manatee protection speed zones in the Canaveral Barge Canal (that is 200 feet wide with a 125-foot navigation channel maintained at a depth of 12.5 feet) such that the entire Canal will now be designated a "slow speed" zone. Sea Ray does not argue that the FWCC did not consider all available information or that FWCC's consideration of the information was not complete. Sea Ray's position is, were one to consider the information presented to the FWCC, as balanced against the federal lawsuit filed by Save the Manatee Club, Inc., the challenged Proposed Rule is the result of the latter not the former and, therefore, is an invalid delegation of legislative authority. Sea Ray alleges that the FWCC did not analyze nor address the adequacy of the existing rule and speed zones in effect in the Canaveral Barge Canal. Sea Ray alleged that the FWCC did not consider the alternative (with weekend boating increases over weekdays) whether the risk to manatees would be reduced by "restricting slow speed zones in the channel to weekend and holidays." Sea Ray alleged that the FWCC failed to apply "properly" the mandatory balancing test of the impact of the proposed rule on the rights of commercial and recreational boaters. Section 370.12(2)(j), Florida Statutes. Sea Ray argues that the FWCC's consideration of information in formulating the Proposed Rule was devoid of "ascertainable quantitative criteria, standards or analytical processes," that Sea Ray maintains is required by Section 370.12, Florida Statutes. Standing Watch, Inc. Standing Watch, Inc.'s, Second Amended Petition challenged and alleged that the proposed speed in proposed Rule 68C-22.006(2)(e) 1-5 is not based upon "competent, substantial evidence" and does not comport with Section 370.12(2), Florida Statutes. Paragraphs 38 and 39 alleged that the proposed speeds in the Proposed Rule 68C-22.006(2)(c) 1-6 and (2)(d) 1-18 are not based upon "competent, substantial evidence" and do not comport with Section 370.12(2), Florida Statutes. Standing Watch, in essence, challenges all "idle," "slow" and "25 MPH" maximum speed zones proposed. Standing Watch argues that the FWCC failed to "quantify" by rule or working definition such terms such as "frequent" and "seasonal" and failed to define the term "periodic." Therefore, without working definitions the FWCC had no "threshold" from which to determine whether manatees were "frequently sighted," and the proposed rule is, accordingly, invalid in its entirety. Thus, it is alleged that the FWCC made no independent findings based upon the data reviewed that manatees were "frequently sighted" in any specific area of Brevard County. Standing Watch alleged, "The genesis of the Proposed Rule is this settlement agreement reached in the Egbert case, and there is a definite connection between the language of the Proposed Rule being challenged and the settlement agreement." Mr. Calleson acknowledged that portions of existing speed zones and proposed speed zones in maps resulting from the federal mediation process contained a "lot of similarities" with the speed zones in maps of the Proposed Rule. The FWCC declined to direct staff to conduct negotiated rule-making on the Proposed Rule. Accordingly, staff's participation in the federal mediation process was not a negotiated rule-making process pursuant to Section 120.54(2), Florida Statutes. Continuing their argument, Standing Watch alleged that the FWCC without algorithms, formulae, protocols, matrices, mathematical models, or metrics made no separate determination for each zone and/or area (of the proposed rule) and had no factual basis for the identification of separate speed zones, rendering all determinations made by the Commission as arbitrary and capricious. Based upon the foregone foundation, Standing Watch challenged Proposed Rule 68C-22.006 in its entirety as arbitrary and capricious. City of Cocoa Beach Watersports Area Cocoa Beach intervened to challenge that portion of Proposed Rule 68C-22.006(2)(d)16, that "reduces allowable speeds in the area known as Banana River, Cocoa Beach Waterspouts Area." In support of its challenge, Cocoa Beach adopted the Proposed Final Order submitted on behalf of Petitioners, Standing Watch, Inc., Jim, Kavin, Thomas Mason, Dougals P. Jaren and Stowell Robertson. Additionally, Cocoa Beach relied upon "facts" particularly applicable to the Cocoa Beach (Waterspouts Area). Cocoa Beach alleged that prior to the Proposed Rule and subsequent to 1988 the FWCC had no evidence of manatee deaths attributed to watercrafts having occurred in the Watersports Area; that two years prior to the proposed rule only one or two manatees were sighted in that area; that the sea grass preferred by manatees is not found in the area, and that the Watersports Area does not have the depth [bathymetry] preferred by manatees. Petitioners contend that a "sub-classification" would corroborate Mr. James Wood's view "a majority of watercraft collisions are caused by large, slow-moving vessels, not by small, recreational motorboats." Mr. Wood's analysis was inconclusive as to the characteristics of watercraft that caused manatee injury. The reliable and available evidence, including documentation on known or suspected boat strikes, scar catalog data, and affidavits of persons who perform manatee necropsies, does not support the view held by Mr. Wood. To the contrary, evidence and testimony of experts herein presented, established that small, fast moving motorboats kill and injure manatees and their habitat. The sub-classification of watercraft-related mortalities is not required for rule adoption. The proposition set forth by McGill Petitioners, and adopted by other Petitioners, that larger vessels and barge/tugs were responsible for Brevard County manatee mortalities was raised in an earlier rule challenge filed by McGill, and was rejected, as it is herein rejected. DOAH Case No. 99-5366, page 18 (officially recognized); Final Order, McGill v. Fish and Wildlife Conservation Commission, 23 F.A.L.R. (DOAH 2000). All data, 1997-1999 Brevard County relative abundance and distribution aerial survey, 2000 synoptic aerial survey, telemetry analyses, other data considered, and professional literature indicated that Brevard County is an important year- round habitat for manatees.
The Issue The issues in this case are whether Respondent, Robert J. Simmons, Jr. (Simmons), should be issued: an Environmental Resource Permit (ERP) under Part IV of Chapter 373, Florida Statutes, and Titles 62 and 40E, Florida Administrative Code; and a Consent to Use Sovereign Submerged Lands under Chapter 253, Florida Statutes, and Chapter 18-21, Florida Administrative Code. (All citations to Florida Statutes refer to the 2000 codification; all Florida Administrative Code citations are to the current version.)
Findings Of Fact The Applicant Respondent, Robert Simmons, Jr. (Simmons), is the applicant for: a consent of use of sovereign submerged lands owned by the Trustees of the Internal Improvement Trust Fund; and an ERP to construct a private, single-family, residential dock for access to Little Munyon Island and to fill jurisdictional wetlands on the island in order to construct a residence on the island. Simmons has offered to purchase Little Munyon Island and the 16 acres of privately-owned, mostly submerged land surrounding it for $2.6 million. Under the contract of purchase, Simmons is required to close by April 2, 2002. If the contract to purchase closes, Simmons plans to construct an 8,000 to 10,000 square-foot residence, with swimming pool, on Little Munyon Island. He estimates that the residence, once built, will be worth $12 million to $15 million. Little Munyon Island. Little Munyon Island is a 1 1/2 acre, undeveloped and unbridged island located in the Lake Worth Lagoon, which has been designated Class III waters of the state. Little Munyon Island is a natural island, one of only three in the Lake Worth Lagoon. Anasthasia rock atop the Pleistocene formation comes to the surface at the site. The island has been enlarged over the years by placement of spoil from dredging of the Intracoastal Waterway (ICW) to the west of the island. In addition, due to erosion on the west and accretion on the east, the island has shifted to the east. Now the eastern edge of the accreted eastern side actually is outside the 16 acres described by the deed Simmons seeks to have conveyed to him. Little Munyon Island is located just south of the John D. MacArthur State Park and Big Munyon Island. The waters in the Park have been designated as Class II, or Outstanding Florida Waters under Florida Administrative Code Rule (Rule) 62-302.700(2)(b). The boundary of the Park is approximately 1,100 feet north of Little Munyon Island. The eastern boundary of the ICW right-of-way is located about 220 feet west of Little Munyon Island; the centerline of the ICW is about 550 feet west of the island. Singer Island is an Atlantic Ocean barrier island approximately half a mile east of Little Munyon Island. The evidence was that less of Little Munyon Island is inundated by high tides than used to be. As a result, more of the island's vegetation was native in the past. Perhaps due to the deposit of spoil material, relatively little of the island is inundated any more. As a result, exotic vegetation such as Australian pine, Brazilian pepper, and seaside mahoe has invaded and comprises about 35 percent of the island's vegetation. The native vegetation includes red, black and white mangroves, buttonwood, and cabbage palms. Although it is private property, Little Munyon Island is currently being used quite extensively by the public, without authorization from the owner. Boaters frequent the island, leaving trash and other debris behind. Visitors to the island have chopped down native vegetation, such as mangroves, in order to build campfires on the island. Boaters visiting the island for recreational activities often ground their boats around the island. Grounding and extricating boats often causes the boats' propellers to dredge up seagrasses and dig holes in seagrass beds. The Lake Worth Lagoon. The Lake Worth Lagoon is a saltwater estuary. It stretches about 21 miles south from PGA Boulevard and varies in width from about 1 to 1 1/2 miles. The Lagoon is tidally influenced twice per day through the Lake Worth Inlet, which is located about 2-3 miles south of Little Munyon Island. The Inlet connects the Lagoon with the Atlantic Ocean. There is a tidal range of 2.8 to 2.9 feet between mean high and mean low tides in the vicinity of the island. Much of the historical extent of the Lagoon has been filled, and it is located in the most urbanized portion of Palm Beach County. From 1940 to 1975, the Lagoon lost more than 87 percent of its mangroves due to shoreline development. Little Munyon Island is located roughly in the middle of a large bay in the northern part of the Lagoon, which has not been filled or bulkheaded. This bay is one of the few remaining natural areas of the Lake Worth Lagoon. The Earman River, also known as the C-17 canal, discharges into the Lake Worth Lagoon west and a little north from Little Munyon Island to the west of the ICW. The part of the Lake Worth Lagoon around Little Munyon Island is vegetated with very high quality seagrasses, including Cuban Shoal Grass (Halodule wrightii), Turtle Grass (Thalassia testudinum), Manatee Grass (Syringodium filiforme), Paddle Grass (Halophila decipiens), and Johnson Grass (Halophila johnsonii). Johnson Grass is a federally listed threatened species of seagrass, but it tolerates a range of water quality and bottom sediments and is relatively abundant in the Lake Worth Lagoon. Five of the six types of seagrasses found in the Lagoon occur in the vicinity of Little Munyon Island. The area around Little Munyon Island is the best area of seagrasses in all of Palm Beach County, and it has the highest density of seagrasses. The quality of seagrasses in the area is "as good as it gets in the Lake Worth Lagoon." The tide from the Lake Worth Inlet flows north and south through the ICW. As a result, the same waters pass both Little Munyon Island and Big Munyon Island as the tide ebbs and flows. Silt and suspended particles in the water column around Little Munyon Island could be carried by the tide to the Class II waters around Big Munyon Island. There is a high degree of biological diversity in the area around Little Munyon Island. The seagrass beds and flats around Little Munyon are a breeding ground for fish and other aquatic resources. The portion of the Lake Worth Lagoon around Little Munyon has been identified as Essential Fish Habitat by the South Atlantic Fishery Management Council and the National Marine Fisheries Service. It is essential fish habitat for postlarval, juvenile, and adult brown and pink shrimp, red drum, and gray snapper. Seagrasses protect small fish and provide a food source for a whole ecosystem that starts with the seagrasses. Seagrasses provide a valuable source of oxygen, food, and shelter. One square meter of seagrass can generate 10 liters of oxygen per day. They may be one of the most prolific ecosystems in the world in terms of biomass production. The water quality in the Lake Worth Lagoon is improving due to stormwater regulation and reduction in the discharge of sewage effluent. This has caused the quality of seagrasses in the area to improve over the past 18 years. Seagrass recruitment has occurred around the area, and new kinds of seagrasses have colonized since 1983. It is reasonable to believe that seagrasses will continue to colonize around the island if water quality continues to improve. If conditions are right, seagrasses can spread and colonize areas where they do not now occur. The Proposed Project Initial Application In the initial application for ERP and consent of use filed on January 20, 2000, Simmons proposed to construct an L-shaped, 5,208 square foot dock made of poured concrete, 10-12 inches thick. The proposed dock's 12-foot wide access pier was to extend westward from shore for 306 feet, with a 12-foot wide terminal platform extending 140 feet to the south. The entire dock was to be elevated to 5.0' NGVD (National Geodetic Vertical Datum of 1929). The entire dock was to be within privately-owned submerged lands, but intended mooring on the western side of the terminal platform would have been over sovereign submerged lands. Initially, the access pier was to cross the center of a sunken barge that lies approximately 240 feet off the island's western shore. In a response on March 10, 2000, to DEP's request for additional information (RAI), the footprint of the proposed dock was shifted south so that the access pier crossed just south of the sunken barge, where Simmons' seagrass consultant, CZR, said there were fewer seagrasses. This also shortened the access pier to 296 feet and reduced the overall area of the docking facility to 5,088 square feet. In addition, mooring piles to the west of the terminal platform were eliminated; as modified, four mooring piles were to be placed parallel to the terminal platform, on the eastern side. As modified, the entire dock structure and mooring area was located within the privately-owned submerged lands. The dock was specifically designed for use in construction of an 8,000 to 10,000 square-foot residence, plus swimming pool, on the island. The terminal platform was designed so that Simmons could moor barges between the terminal platform and the mooring piers and offload needed construction materials and equipment. It was contemplated that the barges would be 55 feet long by 24 feet wide and draw three and a half feet of water and that they would be maneuvered by push-boats. The dock also was designed to permanently moor a vessel 120-140 feet long drawing five and a half feet of water. Simmons intends to live with his family in the proposed new residence on Little Munyon Island. He currently owns a house on the mainland in North Palm Beach on the western side of the Lake Worth Lagoon across the ICW from Little Munyon Island. He plans to park cars and use a dock at that location and operate his boat back and forth to Little Munyon Island. This would necessitate crossing the ICW several times a day. To construct the planned residence and pool on Little Munyon Island, the application proposed construction of a retaining wall around the island, generally no more than 5 feet landward of the perimeter wetlands on the island. Approximately 28,500 square feet (0.65 acres) would be within the retaining wall. Three feet of fill would then be placed within the retaining wall to elevate the pad for the residence to about 6 feet above sea level. Filling the Island would necessitate cutting down all the vegetation inside the retaining wall and filling 0.15 acres of jurisdictional wetlands consisting of mangroves and other wetland species. In the initial application, utilities were going to be provided by directionally-drilling a forced sewer main, water line, electric, cable, phone, and natural gas line from State Road A1A on Singer Island, under sovereign submerged lands in the Lake Worth Lagoon, to Little Munyon. In concerns expressed in the RAI about resource impacts and extension of utilities to an undeveloped coastal island, Simmons deleted the subaqueous utility lines in the modification on March 10, 2000. June Modification During a low, low (spring) tide in April 2000, CZR noticed for the first time that there was a sand bar between the northern third of the sunken barge and Little Munyon Island. In June of 2000, Simmons again modified his application to shift the docking facility back north so that the access pier was aligned with the sand bar. Simmons also proposed to extend the dock out into deeper water, making the dock 376 feet long, and placing the last 33 feet of the dock and the entire terminal platform (a total of 1,230 square feet) on and over sovereign submerged lands. The terminal end of the dock was modified to be 100 feet long by 10 feet wide. The width of the access pier also reduced generally to ten feet; however, over a stretch of 70 feet of the access pier to the west of the sunken barge (where it crossed lush seagrasses), the width of permanent concrete access pier was further reduced to four feet. (Three-foot high, hinged, grated railings designed to fold down would widen the access pier to ten feet on demand. See Finding 37, infra.) These modification reduced the overall size of the docking facility to 4,240 square feet. In addition, the decking was elevated higher, to 5 feet above mean high water (MHW). The mooring piles on the east side of the terminal platform (now over lush seagrasses) were deleted. The house pad and retaining wall were not changed from the initial filing. Having dropped the idea of subaqueous utilities, Simmons proposed "self contained utilities" consisting of: Water - Well with reverse osmosis (RO) plant, as necessary, for potable water. Water for irrigation and toilets will be reused on-site treated wastewater. Drinking water will likely be bottled. Wastewater treatment - Treatment by small on-site package plant, not septic tank. Power - Solar with backup generator. No specifics or analysis of the impacts from these systems were provided, and no assurances were given that they would not pollute. The June modification also proposed mitigation for the loss of the 0.15 acres of wetlands on the island that would be filled. Simmons proposed placement of rip-rap breakwaters just landward of the existing limit of seagrass, or further landward, to provide wave and scouring protection and planting of mangrove and other species landward of the rip-rap. It was suggested that seagrasses also would propagate landward of the rip-rap. In an August 2000 response to DEP's RAI, Simmons detailed the mitigation plan. Under the plan, 350 linear feet of rip-rap breakwaters would be placed along the northwestern and southwestern shores of Little Munyon Island, and the area landward of the breakwaters would be planted with red and black mangrove and smooth cordgrass. Exotic vegetation would be removed from the mitigation areas. Under the plan, 0.31 acres of high quality wetlands would be created to mitigate for the loss of 0.15 acres of jurisdictional wetland fill. DEP Denies Application, as Modified On November 9, 2000, DEP issued a Consolidated Notice of Denial of Environmental Resource Permit and Consent to Use Sovereign Submerged Lands. Discussion focused on impacts on seagrasses, impacts from the proposed utilities, and the mitigation plan. Although DEP noted that the size of the project was reduced from the original application, it concluded that the "dock will still have shading impacts on seagrasses, including Johnson's grass (Halophila johnsonii), a federally-listed threatened species." DEP also noted that the construction of the breakwaters could potentially impact seagrasses. Additional reasons for denial involved the utilities proposed for the uplands. DEP wrote: "The proposed utilities (RO plant, package plant) have a potential for impacts to the Lake Worth Lagoon (Class III Waters) through both a potential discharge and from long-term degradation. Also, no details on the use (short-term or permanent residency) or maintenance of the utilities was provided, both of which could affect how well the utilities function and whether they could affect water quality or habitat." DEP also noted that the proposed mitigation "does not create wetlands. It replaces 0.31 acres of submerged and intertidal habitat with 0.31 acres of mangroves and cordgrass habitat." It was also mentioned that anticipated trimming of mangroves would further reduce the value of mitigation. DEP concluded that Simmons had "not provided reasonable assurance that the construction and operation of the activity, considering the direct, secondary and cumulative impacts, will comply with Part IV of Chapter 373, F.S., and the rules adopted thereunder." DEP specifically concluded the proposal did not meet the balancing criteria set forth in Section 373.414, Florida Statutes, and Rules 62-330, 40E-4.301 and 40E-4.302. Third Modification and DEP Intent to Issue Simmons and his lawyer and consultant met with DEP staff in November of 2000. A site visit was made on December 8, 2000. After the meeting and site visit, Simmons proposed to further modify the project in several respects. The portion of the dock that was previously reduced to 4 feet in width was proposed to be constructed with a grated deck. The dock was elevated from 5.0 feet above MHW to 5.25 feet above MHW measured at the top of the deck. The design of the rest of the dock remained the same. No changes were proposed to the retaining wall or filling of wetlands. As for utilities, Simmons proposed the "Little Munyon Island Power and Sewerage Plan" This plan represented that 90 percent of the complex's power would be provided by solar energy, producing approximately 72 kilowatts (kW) of electricity. The plan also stated: "Water treatment both for drinking and waste waters will be processed through Atlantis Water treatment Auto Flash systems. This approach will use waste heat to evaporate and clean the water. This process will return used waters to potable with no more than 5 percent effluent. Any effluent will be secured and containerized and periodically (2xs per year) removed from the island." An "auto-flash" system creates distilled potable water using waste heat to evaporate all water from the effluent. The new Little Munyon Island Power and Sewerage Plan did not mention the use of irrigation waters on Little Munyon Island. DEP's staff reviewer understood from the new plan that there would be no wastewater irrigation on Little Munyon Island and that all waste would be processed by distillation, i.e., potable water. As for the mitigation plan, the two previously- proposed rip-rap breakwaters were modified to reduce their footprints, and the southern breakwater was moved somewhat landward at the southern end to avoid seagrasses. A third breakwater was added to the north side of the island. This increased the amount of mitigation area from 0.31 to 0.36 acres. In addition, Simmons submitted a revised mitigation plan to plant mangroves and spartina behind the breakwaters. Simmons also offered to record a conservation easement on the 16 acres of privately-owned submerged lands surrounding Little Munyon Island. DEP issued a Consolidated Notice of Intent to Issue Environmental Resource Permit and Consent to Use Sovereign Submerged Lands on March 12, 2001. In recommending this action, DEP's staff reviewer understood that there would be no discharge whatsoever on the island under the "Little Munyon Island Power and Sewerage Plan," and that all wastewater would be recycled and reused. Specific Condition (18) stated: "Power and wastewater service for the island shall be provided as described in the attached 'Little Munyon Island power and sewerage plan'. No discharge of effluent is authorized on the island." DEP's staff reviewer understood the permit to mean that "water, the material that comes out . . . of the other end of the waste water system" would not be discharged on the island. If DEP's staff reviewer knew Simmons was planning to use another system to treat wastewater or was planning to discharge reuse water on the island, it "would have been a concern," and he "would have questions about what that involved." He agreed that "spray irrigation would have been a concern" and would have raised issues related to the level of treatment, water quality and quantity and runoff from the upland part of the island into the waters of the Lake Worth Lagoon. The main concern would have been nutrients. In granting the revised application, DEP reversed its previous conclusions that Simmons had not complied with applicable statutory and rule criteria, and specifically found that "the Department has determined, pursuant to Section 380.0651(3)(e), F.S., that the facility is located so that it will not adversely impact Outstanding Florida Waters or Class III waters, and will not contribute to boat traffic in a manner that will adversely impact the manatee." The Challengers The proposed project is opposed by Petitioner, Singer Island Civic Association, Inc. (SICA), and by Intervenor, 1000 Friends of Florida, Inc. (Friends). SICA and Friends are both Florida corporations. SICA commenced this proceeding by filing a verified Petition for Administrative Hearing. Friends filed a verified Petition to Intervene. It was stipulated that SICA and Friends have standing as Florida citizens under Section 403.412(5). SICA also asserted standing based on the proposed project's effects on its substantial interests and those of its members. SICA is a membership organization with 1,200 members, who reside on Singer Island. SICA has an office located at 1281 North Ocean Drive, Singer Island, Florida. It also owns submerged real property in the Lake Worth Lagoon just west of and adjacent to Singer Island. SICA's membership includes individuals and condominium associations. Several individual members and condominium association members own property that borders State Road AIA on Singer Island. Some have riparian rights to the Lake Worth Lagoon. SICA performed a survey of its members and received 330 responses. Ninety percent of those responding believed they would be affected by the proposed project. More than 75 percent said they fished in the Lagoon and believed the project would hurt fishing; 80 percent said they enjoy and study the wildlife around the Lagoon; and 72 percent believed wildlife viewing would be impacted by the project. Members of SICA use the Lake Worth Lagoon for boating, fishing, recreation, or enjoyment of wildlife. The membership and the corporation are concerned about the potential of the project to pollute the Lake Worth Lagoon and adversely affect the environmental resources of the Lagoon. SICA's purpose includes the preservation of the environmental resources of the Lake Worth Lagoon and opposition to proposals to fill the submerged lands along State Road AIA. The type of relief sought by SICA in this action is the type of relief that is proper for the corporation to seek on behalf of its members. Both SICA and a substantial number of its members are substantially affected by Simmons' proposed project. A number of issues raised by SICA and Friends were dropped by the time the parties filed their Prehearing Stipulation. SICA and Friends further refined their claims at final hearing. The remaining challenges to the project focus on turbidity and shading of seagrasses caused by the construction and operation of the project, as well as on the potential secondary impacts of utilities proposed to serve the residence on the island. Direct Impacts from Proposed Dock The proposed dock is significantly larger than a typical private, single-family dock. No other of its proportions can be found in Palm Beach County. Typically, private, single-family docks are four-feet wide and made of wood, with spaced wooden planks for decking. The proposed docking facility's size and construction technique are more typical of a commercial docking facility. A docking facility of the size and kind proposed is not required for reasonable access to Little Munyon Island. Rather, it is required for construction and maintenance of a 8,000 to 10,000 square-foot residence, plus swimming pool, that will be worth $12 million to $15 million when completed. A less intense use of the island would have fewer impacts on the environment. Alternatively, there are other ways to build a house on the island without constructing a permanent dock of this size. Simmons might be able to push a barge temporarily up to the island, construct the house and then mitigate for the temporary impacts of beaching the barge. Simmons also might be able to construct a temporary span of trusses, a system used by the Florida Department of Transportation when working on coastal islands. The amount of shading caused by a docking facility is influenced by numerous factors. But if other factors are equal, generally the larger the surface area of the dock, the more shading occurs; likewise, solid poured concrete decking shades twice as much as grated decking material. As a result, all other factors being equal, the proposed dock will produce more shade than a typical private, single-family dock. In addition, there is a halo effect around the footprint of a dock that is about 2.25 times the square footage of the dock. The area under solid concrete decking will receive no sunlight. No seagrasses will ever grow in this area, eliminating possible recruitment of seagrasses in this area. Simmons made a laudable effort to locate, configure, and orient his proposed docking facility so as to reduce the shading impact of the dock's footprint and halo effect. The use of grated material over the area of greatest seagrass cover also was appropriate. But shading impacts and halo effects were not avoided entirely. In its April 2000 biological survey, CZR depicted an area approximately 40 feet wide by 250 feet long between the west of Little Munyon Island and a sunken barge as a "barren," meaning it had no seagrasses. Clearly, sand has built up over the years in this area due to influence of the sunken barge, and parts of the sandbar may be exposed at every mean low tide. This area may be devoid of seagrasses. But other parts of the sandbar may only be exposed at every low, low (spring) tide and may not actually be "barren." An onsite inspection and video tape of the area was made by Carman Vare of the Palm Beach County Division of Environmental and Resources Management in August of 2001. This inspection and video confirmed that there were no seagrasses in the sandy area from the mean high tide line on Little Munyon Island running west along the proposed footprint of the dock for a distance of approximately 130 feet. But at a point approximately 130 feet from shore, within 5 feet north of the tape placed at the presumed centerline of the proposed dock and sandy area, Vare began to find rhizomes (roots) of Cuban Shoal Grass (Halodule wrightii) in the sediment. Rhizomes of this seagrass continued to be found out to approximately 182 feet from the shore. At that point, sparse patches of Johnson Seagrass began approximately 5-10 feet north of the tape. This type of grass continued to be found to a point roughly 205 feet from the shore. From 205 feet to 215 feet from the shore, Cuban Shoal Grass rhizomes reappeared. There were no seagrasses from 215 feet to the east edge of the barge, which is approximately 243 from the shore. The area around the barge has been scoured out by waves and currents. It is possible that Vare placed his tape somewhat north of the actual centerline of the proposed dock. It is not clear from the evidence, but a sunken piling Vare swam over at one point may have been north of the centerline of the proposed dock. Also, while no seagrasses were observed when Vare swam south of the tape, Vare did not swim further than 5 to 10 feet south of the tape, so he did not know how far south of his transect line the area was barren of seagrasses. In any event, it was clear that the entire area depicted by CZR as "barren" was not in fact completely devoid of seagrasses; there were seagrasses and seagrass rhizomes either within the footprint of the proposed dock in the 110 feet or so east of the sunken barge, or very close to the north of the footprint in that locale. The sunken barge is made of decomposing wood. It is about 30 feet wide and about 100 feet long. It is often exposed at low tides, but is submerged during high tides. While there are no seagrasses growing in the barge, the barge is providing some fish habitat. If the barge were removed, seagrasses probably would re-colonize the area. West of the barge for approximately 50 feet is a colony of lush Cuban Shoal Grass. Coverage is sparse very near the barge but quickly thickens to the west to approximately 75 percent coverage. (CZR mischaracterized the density of this grass as 30 percent, perhaps in part because CZR did not conduct its surveys during the optimal growing season). From 50 to 70 feet west of the barge, CZR found moderate (30 percent) cover of Paddle Grass (Halophila decipiens). There are no grasses from 70 to 103 feet west of the barge. However, CZR found moderate (30 percent) cover of Paddle Grass south of the proposed footprint of the access dock and east of the terminal platform, extending south past the end of the terminal platform. The proposed terminal platform is in approximately 8-9 feet of water. The sediments under the terminal platform are composed of sand, silt, clays and organic materials. There are no grasses under the proposed terminal platform. The terminal platform would be directly over lush beds of Halophila decipiens (paddle grass) and Halodule wrightii (shoal grass) if the proposed dock were shortened by 35 feet, as Simmons has suggested to avoid having to obtain consent of use of sovereign submerged lands. Secondary Impacts from Proposed Dock As indicated, Simmons plans to use the proposed docking facility for construction and maintenance of a 8,000 to 10,000 square foot residence. He plans to use 55-foot long construction barges, drawing 3-4 feet of water, to bring fill, rocks, and other construction materials to Little Munyon Island. The barges will be moored to the western side of the proposed terminal platform. The use of construction barges will cause turbidity during construction. Simmons proposes to offload tons of fill from the barge and carry this fill over the dock to Little Munyon Island. One estimate was that, if Simmons used barges 120-130 feet long and capable of hauling 300 tons of fill, he would need to deliver 27-30 barge loads of fill to the dock. There is a reasonable likelihood that some of this fill will fall into the water. Simmons provided no analysis of the impacts of offloading and delivering this much fill to the island. There was no evidence of how Simmons planned to move sand around to fill the island, or its potential to cause turbidity. The location of the proposed dock in this case complicates the navigation of barges and vessels to and from the dock. Little Munyon Island is roughly centered in the Lake Worth Lagoon; and, except for some protection from the island itself, the dock is fully exposed to wind from all directions. Meanwhile, the "sail effect" of large boats adds to the difficulty of navigating them in the wind. The proposed dock also is exposed to the full effect of the current. A tidal range of a couple of feet can cause a current of about 1-2 knots; mean tidal range in the location of the proposed dock is as much as 2.8 to 2.9 feet. Finally, the proposed dock is near the ICW, which has a lot of boat traffic and wake. All of these factors can affect maneuverability of boats, create closure problems, or push the boats away from the dock. Unless Simmons wants to run the serious risk of losing control of the construction barges and inadvertently damaging seagrass beds, he will have to use a tug with significant maneuvering power. Tugs create more hydraulic thrust than other vessels because they generate more torque. Tugs also have more prop wash than most boats because they have deeper draft and larger propellers, in the range of 3 1/2 feet in diameter. The proposed dock was designed to moor a vessel up to 120-foot long parallel to the western side of the terminal platform when not being used for construction barges. If not being used for either barges or one large vessel, the mooring could accommodate two vessels of between 50-60 feet in length. Although not contemplated or ideal, it would be physically possible to moor three large vessels west of and perpendicular to the terminal platform inside the four mooring piles located 40 feet off the terminal platform. (These piles are 33 feet apart and designed to secure the construction barges, or one large vessel, parallel to the western side of the terminal platform.) While there are railings on the access pier to discourage mooring, there are no railings on the terminal platform. It also would be possible to moor boats on the east side of the terminal platform, which would be over lush seagrass beds. Simmons plans to moor his boat there when the western side is occupied by construction barges. Boats of 50-60 feet usually have twin inboard engines that range from 400 to 600 horsepower each. They can have propellers of between 26-30 inches in diameter. The engines and propellers are installed in a declining angle on such boats with the thrust vector pointing downward toward the bottom. Boats in this size range generally of draw 4-6 feet of water depending on the size and type of the vessel. A 70- foot trawler draws 6 feet of water. Unlike outboard engines (which also typically are lower-powered), inboard engines do not turn. Larger vessels move around by employing differential power. With twin inboard engines, navigation can by accomplished by using power pulsing, using the engines at different speeds, or by making one engine push forward and the other push in reverse. Winds and currents increase the need to use pulse powering to maneuver into and away from docks. For these reasons, the operation of 50-60 foot boats even in 5-10 feet of water can disturb the bottom through hydraulic scouring. As indicated, tug boats maneuvering a barge can scour the bottom even more. DEP's staff concluded that the operation of the dock would have no effect on seagrasses and sediments and would not cause turbidity or scouring problems in part by applying a longstanding policy which assumes that turbidity will not be a concern if one foot of water is maintained between boats using a dock and the bottom. The permit contains a condition that Simmons maintain one foot below boats. The so-called one-foot rule was designed for small, outboard-powered boats. As larger and more powerful vessels have increasingly used Florida's relatively shallow waters, the rule has become antiquated and ineffective for protection of marine resources from scouring and turbidity. Certainly, it will not be effective to minimize the impacts of scouring and turbidity from vessels of the size authorized and expected to use this dock. The so-called one-foot rule also does not differentiate between types of sediments. There is a "hole" approximately under and just west of the northernmost 60 feet of the proposed terminal platform; the hole also extends to the north beyond the proposed terminal platform. The water in the "hole" is approximately 8 feet deeper than the surrounding areas. The "hole" has been there for years. It could have been caused by dredging back in the 1940s. It also is just west of where a previous dock was located and could have been caused by prop-dredging (or perhaps by a paddlewheel, which used the mid-1960s). The "hole" is a silt trap. There is approximately 5 feet of silt in the bottom of the "hole." The sediment in the hole consists of very fine particles of muck and silt, with some decomposing drift algae. The silts in the "hole" probably come from the Earman River, which drains urbanized areas of North Palm Beach and discharges into the Lake Worth Lagoon just across the Lagoon from the site. There are no seagrasses in the "hole." Neither CZR nor DEP knew the "hole" was there. CZR did not identify it on its biological survey. Simmons provided no analysis of the sediments in the hole or in the mooring area of the proposed dock. DEP provided no analysis or testimony of the effect of the sediments in the "hole" on turbidity and water quality. Silts and muck cause turbidity, which is a measure of water clarity. Re-suspended mucks and silts can impact seagrasses by reducing light penetration through the water and by settling on their leaves. Silts stirred up from the operation of tugboats and large boats at the end of the proposed dock could settle on the grasses under the 4-foot grated area and negatively impact the very seagrasses that DEP was trying to protect. Once re-suspended, sediments can persist in the water column for 20-40 minutes, depending on the currents. A knot or two of current can suspend silts for half an hour and transport them a mile away. On an incoming tide, such a current could transport re-suspended sediments toward and into MacArthur State Park, just 1,100 feet away. To determine the extent of degradation of the turbidity standard in the OFW of the State Park, DEP would have to know the background turbidity in the Park. Neither Simmons nor DEP did a hydrographic survey or any other analysis of the project for its effect on the OFW. Farther west of the proposed terminal platform, the bottom rises out of the "hole" to a depth of 8-9 feet. Starting there, and extending west all the way to the edge of the ICW, there is sparse but continuous Paddle Grass (Halophila decipiens). Allison Holzhausen, an environmental analyst with Palm Beach County, has run transects throughout the area of Lake Worth Lagoon between the proposed terminal platform and the ICW and has not found any place in that area where seagrasses did not grow. Water depths in this area do not exceed approximately 14 feet. Depending on water clarity, Paddle Grass can grow in deep waters and have been found in water up to 25 meters deep in the Atlantic Ocean off Palm Beach County. CZR provided no biological survey of the seagrass communities west of the mooring area, nor did it analyze the resources or do a bathymetric survey of the area between the proposed dock and Simmons's dock on the mainland west of the ICW. This information would be needed to determine whether the operation of Simmons's boat to and from the dock on a continuing basis would impact seagrasses and to locate the best place for a channel. If the proposed dock were shortened by 35 feet, as Simmons has suggested to avoid having to obtain consent of use, the terminal platform and mooring areas would be directly over lush seagrass beds. In addition, the water there would be just 6.4 feet, or less, at MLW (mean low water); there was no evidence of detailed bathymetric information in the area. Depths would be even lower at low, low (spring) tides. Several witnesses testified that the 7.4 foot depth in the area indicated on Sheet 3 of 5 of the Plan View in Simmon's application was at MLW. But Sheet 3 of 5 indicates that "datum is NGVD," meaning the National Geodetic Vertical Datum of 1929, and Sheet 4 of 5 of the Plan View indicates that MLW is approximately a foot less than NGVD. Impacts on seagrasses from scouring and turbidity would be even greater if the proposed dock is shortened by 35 feet. Secondary Impacts of Wetland Fill When DEP gave notice of intent to issue the Permit, it was operating under the assumption and promise that there would be "no discharge" of wastewater on Little Munyon Island. Under the proposed "Auto-Flash" wastewater system, the only effluent would be solid "sludge," which would be removed from the island twice a year. This assumption continued into final hearing. On August 7, 2001--after the permit was issued, and just a couple of weeks before final hearing--Simmons proposed a different type of wastewater treatment system that would spray-irrigate treated wastewater. The new proposed system would provide aerobic and anaerobic treatment, filter the effluent, chlorinate it, and then spray it at a rate of up to 1,040 gallons per day onto the surface of the Little Munyon Island within approximately 50 feet of the water's edge. In effect, Simmons went back to his original proposal for a "waste water treatment/treatment by small on- site package plant not septic tank . . . water for irrigation and toilets will be re-used onsite treated wastewater." This system was rejected by DEP in its denial of November 4, 2000, because it lacked information on the facility and whether there would be a discharge. DEP's engineers did not review the system again after August 7, 2001. The disposal of treated effluent from the onsite sewage treatment plant raises legitimate concerns over the potential of the proposed utilities to impact surface waters. Simmons's engineer, John Potts, conceded that there will be nutrients in the wastewater. Nutrients from wastewater can cause algae to grow, which affects the health of seagrasses. Potts was unable to provide detail as to the amount of nutrients and other constituents of the wastewater. DEP's experts were not familiar with the criteria for reuse of treated effluent. DEP did not know the transmissivity of the fill and could not say whether treated effluent sprayed on the island would percolate through the fill and run into the Lagoon across the top of the rock strata on the island. Potts did not know how stormwater would be handled on the island; a proposed stormwater system has yet to be designed. For that reason, Potts could not say whether the sprayed treated effluent could reach the Lake Worth Lagoon. DEP also did not know how stormwater was proposed to be treated on site. The solar power system proposed in the Little Munyon Island Power and Sewage Plan would only produce only 31 kW of power and provide 19 percent of the complex's power and at peak times, not the 90 percent estimated by Simmons's consultants. In effect, the propane generator was not a "backup," as suggested, but the main power source for the house and utilities and only source of power for the wastewater treatment system, since the generator must be running to provide waste heat for the wastewater system to work. Instead of two available sources of electrical power for the wastewater treatment system in case one failed, there is really only one, the propane generator. The lack of any backup for the sewage treatment system increases its potential to fail and adversely affect surface water quality and the marine environment of the Lake Worth Lagoon. DEP did not analyze stormwater or the discharge of treated wastewater and its effect on surrounding waters, stating: "Typically we don't review storm water for single family residences." But Simmons's proposed project is not a typical single family residence. In rebuttal, Simmons put on evidence that there would be approximately 14,800 square feet between the retaining wall and the 50-foot setback line and that the depth of 1,000 gallons of sprayed treated wastewater would be only one-tenth of an inch if sprayed equally over that entire area. Evapotranspiration alone would account for the entire 1,000 gallons, according to the Basis of Review of the South Florida Water Management District. But the evidence was not clear as to how much of the 14,800 square feet between the retaining wall and the 50-foot setback would be available for spray irrigation. The weight of the evidence was that Simmons failed to provide reasonable assurances that the disposal of wastewater on the island will not have adverse impacts on the marine resources of the Lake Worth Lagoon unless a specific conditions were added to the permit: that a properly designed and constructed stormwater system be established prior to operation of the sewage treatment facility; and that backup systems and emergency procedures be established in the event of any failure of the main system.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order denying the application of Robert Simmons, Jr., for an ERP and Consent of Use for his proposed docking facility.

The Issue Whether the Department of Environmental Protection should issue a Consolidated Environmental Resource Permit and Sovereign Submerged Lands Authorization to Deep Lagoon Boat Club, Ltd., for the upgrade of its existing commercial marina in Deep Lagoon, an arm of the Caloosahatchee River?
Findings Of Fact The Caloosahatchee River Located in Lee County and considered a part of Charlotte Harbor, the Caloosahatchee River (the "River") is among the Class III surface waters of the state, so classified on the basis of the designated uses "Recreation, Propagation and Maintenance of a Healthy, Well-Balanced Population of Fish and Wildlife." Fla. Admin. Code R. 62-302.400(1). The River runs from Lake Okeechobee in a southwesterly direction past the City of Ft. Myers into San Carlos Bay. The bay, adjoining the Gulf of Mexico, is directly south of Matlacha Pass. It sits in the midst of, and is formed by, Sanibel Island, Pine Island, and the land masses on the north side of the Caloosahatchee (the site of City of Cape Coral) and the south side that culminates in Shell Point, at the mouth of the River. Beginning 120 years ago or so, the River underwent a series of major man-made alterations. Together with a statement of the current status of the River, they are summarized briefly in a publication of a recent special study of manatees and the River by the Florida Fish and Wildlife Conservation Commission's Florida Marine Research Institute (the "Special Study"). (Highly pertinent to this case, the Special Study is referred to elsewhere in this order.) This is its summary of the alterations to the River: Prior to the late 19th century, the Caloosahatchee River was a meandering waterway that ran from west Lake Flirt to San Carlos Bay . . . In 1881, Hamilton Disston began dredging a canal to connect the river's headwaters with Lake Okeechobee (citation omitted). This procedure caused severe flooding downstream, especially during the hurricane season. To mitigate the flooding effects, various spillways, locks and dams were constructed, including the locks at Moore Haven and Ortona. In 1947, the Central and Southern Florida (CS&F) project was authorized to manage the flood-control system and water supply issues of the Caloosahatchee River basin. The CS&F project involved widening and straightening the river and constructing the Olga Lock and Dam (now known as the . . . Franklin Lock and Dam). The river today is 65 miles long with a 25- foot-deep channel. Petitioners' Exhibit 20, A Special Study of Manatees in Mullock Creek and the Caloosahatchee River Eastward to the Edison Bridge, Florida Fish and Wildlife Conservation Commission, Florida Marine Research Institute, November 2002. Despite these alterations, the River is listed among the waters of the state designated as Outstanding Florida Waters. Fla. Admin. Code R. 62-302.700(9)(b)2. As such, it is entitled to special protection by virtue of DEP's pronouncement that "[I]t shall be the Department policy to afford the highest protection to Outstanding Florida Waters". Fla. Admin. Code R. 62- 302.700(1). The Franklin Lock is located on the Caloosahatchee about 25 miles upstream from San Carlos Bay. The lock permits fresh water to flow downstream toward the bay, of course, but it keeps the salt in brackish waters in the River south of the lock from penetrating upstream. In other words, the lock is a salinity barrier. The estuarine extension of the River, therefore, is defined by the lock. Little more than four miles downstream from the lock, the Orange River feeds into the Caloosahatchee. Upstream on the Orange, not far from its mouth, is the site of a Florida Power and Light Company ("FP&L") power plant. Until very recently, the power plant discharged into the Orange River effluent roughly seven degrees Celsius warmer than its ambient waters. (Waters discharged now are not as warm but still significantly warmer than the River's ambient water.) The warmed waters flow into the Caloosahatchee. These river system waters warmed by power plant effluent are sought by manatees as refuge from colder water in the River, the bay and the gulf. "Controlled releases or pulses of fresh water from Lake Okeechobee, upstream runoff, and prolonged periods of drought can severely, though temporarily, alter the salinity gradient [downstream of Franklin lock]." Id. at p. 20. It is believed that the variations in salinity affect seagrass biomass more than actual salinity levels. The salinity ranges cause turbidity and decrease in water clarity in the Caloosahatchee. They darken the water color and result in the submerged aquatic vegetation being variable and patchy instead of plentiful as it would be were the River not affected by rapid and extreme salinity changes. The River is crossed by a number of bridges: the Interstate 75 Bridges, Edison Bridge (part of U.S. Highway 41), the Midpoint Bridge, and the Cape Coral Bridge. The average depth of the water at river's edge is three feet. The center, including the channel, ranges from 6 to 25 feet in depth. Relatively shallow, the length and breadth of the River is traveled by manatees who use it as a critical link in habitat in southwest Florida. Manatee Habitat Linkage The presence of manatees in the River and their use of it for habitat is also summarized in the Special Study: The Caloosahatchee River between the Edison Bridge and Shell Point links habitats used by manatees including warm-water refugia, feeding areas, and resting areas. Because of drastic changes in salinity . . . coupled with high turbidity from development and vessel traffic, the distribution of submerged aquatic vegetation (marine and freshwater) in the study areas is variable and patchy. Manatees travel between stable feeding areas found upstream (freshwater) and downstream (estuarine), although they presumably feed opportunistically while passing through the area. Selected areas in the Cape Coral and Ft. Myers canals likely afford manatees with fresh water through stormwater runoff and drainage, resting habitats, and possible nursery areas. In winter, manatees may also use a few of these canals as temporary warm- water sites. Id. Among the places along the River where manatees congregate is Deep Lagoon. Deep Lagoon Deep Lagoon is a natural, relatively short, largely mangrove-lined arm of the Caloosahatchee on its southern shore just east of Palmetto Point. The lagoon is to the west and south of the downtown area of the City of Ft. Myers, less than a mile south of the southern terminus of the Cape Coral Bridge, and approximately 12 miles downstream from the FP&L power plant. Roughly four miles upstream from Shell Point where the River opens to the bay, the mouth of the lagoon opens west. Just inside the lagoon's mouth, it widens into an area known as the Cove. The lagoon turns 90 degrees to the south and extends in a southerly direction toward McGregor Boulevard. The upper reaches of the lagoon, or its headwaters, very close to McGregor Boulevard, are known as Cow Slough. Like the Caloosahatchee, Deep Lagoon is one of the Class III waters of the state. Unlike the River, the lagoon is not listed among the Outstanding Florida Waters. Wildlife in the area around Deep Lagoon include great blue herons, night herons, osprey and other hawks, and, of course, the manatee. In fact, Deep Lagoon is considered by the Bureau of Species Management in the Florida Fish and Wildlife Conservation Commission (the "FWC") to be a "minor aggregation area" (Tr. 792) for manatees. The lagoon provides some warm waters attractive to the manatee, and manatees consume fresh water discharged into the lagoon from the Iona Drainage District ditch. (See paragraph 17, below.) The waters in and near the lagoon are frequently used by citizens for fishing. Fly fishing for snook, redfish, snapper, sea trout, and sheepshead is particularly popular in and about the lagoon. The lagoon is also the site of the Boat Club's Deep Lagoon Marina. The Deep Lagoon Marina The Deep Lagoon Marina (the "Marina") consists of 24 acres less than one-half mile from the River, north of Cow Slough, and south of the Iona Drainage District ditch. The Iona Drainage District ditch, the result of the first dredging in the Deep Lagoon area, is separated from the Marina by a relatively thin strip of mangrove fringe. It is a source of fresh water runoff from predominately fresh water wetland and upland areas. It appears in a 1944 aerial photograph that pre-dates dredging for the marina or of the lagoon otherwise. An aerial photograph taken in 1958, 14 years later, shows development of the Deep Lagoon marina property, as well as completion of a north canal separated from the Iona Drainage Canal by the mangrove fringe. Sometime between 1958 and 1966, two additional canals were dredged as part of the Marina. The marina consists of 15.4 acres of uplands, largely the result of the dredge and fill activity that created the marina's three man-made canals: the "north canal"; the "main canal" that includes a basin (the "main basin") at its eastern end; and the "south canal." At their eastern ends, the three canals terminate a short distance from MacGregor Boulevard. On their opposite ends to the west, the canals open to the lagoon. Except for the Iona Drainage District ditch that discharges into the north canal, the canal water system has little circulation. Within the dead-end system the canals comprise, the water sloshes back and forth. The dead-end nature of the canals has led to violations of water quality standards as found in paragraphs 4 and 5 of Sheridan, et al. v. Deep Lagoon Marina, et al., Case No. 88-4759 (DOAH June 10, 1989): As a result of poor water circulation within the system, sediments have built up in the canal bottoms and in the basin. Although different historical incidents, such as ship building, the burning of a large building on the east-west peninsula and the receipt of agricultural and highway drainage into the northern canal may have caused some of the build-up, marina activities and the use of the canals for marina purposes have contributed significantly to the problem. Water quality samplings within the canals and basin indicate that State Water Quality standards are currently being violated for dissolved oxygen, oils and greases, total and fecal coliform, copper, lead, mercury and tributylin. Sediments in the canals and basins are contaminated by lead, copper, cadmium, chromium and mercury. The canals and basin are currently devoid of seagrasses, oyster beds and benthic organisms. Id. at pp. 4 and 5. The north peninsula (referred to in other DOAH orders as the "east-west peninsula") is the longer of the two peninsulas on the marina property. It lies between the north canal and main canal. The south peninsula lies northeast of the south canal, southwest of the main basin, and south of the main canal. Two steel buildings used for dry boat storage, a building used for boat repair and related marina uses are located on the south peninsula. The marina property located east of the marina's two peninsulas that fronts MacGregor Boulevard is occupied by a boat dealership and the Boat Club's sales trailer. To the north of the marina is the Town and River subdivision. The subdivision has an extensive canal system. Like the marina's canals, the Town and River Canal System is also the result of historic dredge and fill activity. As the Town and River subdivision expanded in the 1970's, the use of the marina increased. A boat storage building appears on the north peninsula in a 1970 aerial photograph. Extensive outdoor dry boat storage on the north peninsula began in the late 1970's. Dry boat storage expanded in the 1980's. An examination of aerial photography taken in 1990, 1993, 1999, 2000, and 2001, reveals 1990 to be "the period of time that the facility appeared to be at full operating capacity." (Tr. 787). As early as March 23, 1980, a travel lift facility appears in aerial photographs at the west end of the north peninsula. The boat lift appears in the same spot on the western end of the northern peninsula, west of the longitude at which the Iona Drainage District canal opens onto the North Canal, in a series of aerial photographs taken over the next two decades. The area surrounding the marina is fully developed, including the residential areas and boat basins to the north and south. Opposite the marina and along much of the western border of the lagoon, there is a vacant tract of wetlands. Purchased by Lee County as conservation lands, it will not be developed. It is the Department's position that Deep Lagoon Marina can operate as a marina without a permit. But a permit is required if its owners seek to upgrade the marina by activity that trips permit requirements such as construction or dredging of channels. The Boat Club became involved in permitting processes soon after it purchased the marina. Purchase by the Boat Club The Boat Club purchased the marina in 1997, with a closing on the purchase in September of that year. At the time of the purchase, it was the Boat Club's intent to redevelop the entire marina property and upgrade its facilities under the authority of development orders and permits obtained by the former owners. These included a Development of Regional Impact Development Order (the "DRI DO") issued in 1987; a surface water management permit (the "MSSW permit") from the South Florida Water Management District issued in 1988; and a dredge and fill permit from the former Department of Environmental Regulation issued in 1989, and extended through a major modification in 1995. A Litigious History These permits have a litigious history, particularly the dredge and fill permit and its conditions. Modifications to the permit resulted in additional permit processes, including administrative hearings. The history of the dredge and fill permit litigation, including litigation related to the Boat Club's application for an environmental resource permit to construct a surface water management system (the "SWMS permit") at the marina site is summarized in a final order of the Department of Environmental Protection rendered March 6, 2000 ("Sheridan III"): Applicant [Deep Lagoon Boat Club, Ltd., or, as referred to in this order, the Boat Club] is the owner and operator of Deep Lagoon Marina (the "Marina"), presently consisting of 61 wet slips, 200 dry slips and other marina-related buildings. * * * In 1989, the Department of Environmental Regulation ("DER") entered a final order issuing a dredge and fill permit to a predecessor in title of Applicant authorizing a major renovation and expansion of the Marina, including additional boat slips and other related activities. See Sheridan v. Deep Lagoon, 11 F.A.L.R. 4710 (Fla. DER 1989). The final order in the original Sheridan case was appealed and the portion thereof issuing the dredge and fill permit was subsequently affirmed by the appellate courts Sheridan v. Deep Lagoon, 576 So. 2d 771 (Fla. 1st DCA 1991). A permit was ultimately issued by the Department in October of 1995 (the "Original Permit") after the conclusion of the appellate proceeding. The Original Permit was modified by the Department in November of 1995 and again in April of 1997. This 1989 DER final order in the original Sheridan case adopted the hearing officer's findings that the waters of the Marina canals violated water quality standards for dissolved oxygen, oils and grease, total and fecal coliform, copper, lead, and mercury. Sheridan, supra, at 11 FALR 4727. These persistent water quality violations in the marina canals in the 1980's were the impetus for specific conditions set forth in the Original Permit issued by the Department in 1995 to ensure a net improvement" to water quality. Specific Condition 5K of the Original Permit, as revised in 1997, requires that a "stormwater treatment system providing treatment meeting the specifications of Florida Administrative Code 40E-4 for all discharges into the basins from the project site shall be permitted and phased in prior to use of the parking lot and the new boat slips." . . . In order to meet these requirements of Specific Condition 5K of the Original Permit, Applicant filed an application with the Department in December of 1997 for an environmental resource permit to construct a surface water management system at the Marina site. The Department executed a Notice of Intent to Issue Applicant's requested permit for the surface water management system (the "SWMS" permit) in November of 1998. In March of 1998, Applicant also gave the Department written notice that it intended to "maintenance dredge" the internal canals at the Marina site. The Department's South District Office then issued a letter determining that Applicant's proposal to maintenance dredge the Marina's internal canals was exempt from environmental resource permitting requirements. Upon receipt of this letter from the Department, Applicant's contractor proceeded with the "maintenance dredging" of the three canals. Petitioner and Intervenor then filed petitions challenging the Department's notice of intent to issue the SWMS permit and the Department's maintenance dredging exemption determination. These petitions were forwarded to DOAH and were consolidated for final hearing in Sheridan v. Deep Lagoon Boat Club, DOAH Case Nos. 98-3901 and 98-5409 ("Sheridan II"). A recommended order was entered in Sheridan [II] in November of 1999 by a DOAH administrative law judge ("ALJ"). The Department subsequently entered a final order in January of 2000 in the Sheridan [II] consolidated cases. See Sheridan v. Deep Lagoon Boat Club, OGC Case Nos. 98-1184 and 98[-]3047 (Fla. DEP, January 28, 2000) In its final order in Sheridan [II], the Department adopted the ALJ's conclusion that Applicant failed to establish at the final hearing that the already completed dredging of the three Marina canals complied with two of the statutory requirements for entitlement to "maintenance dredging" exemption. The Sheridan II final order also adopted the ALJ's conclusion that Applicant failed to provide reasonable assurance that the secondary impacts of the operation of the proposed SWMS would not violate water quality standards and would not adversely impact the West Indian manatee. The Sheridan [II] final order of the Department thus disapproved the prior determination of Department staff that Applicant was entitled to a permit exemption for maintenance dredging of the Marina Canals [although the matter was moot since the Boat Club had, in fact, conducted the dredging while the proceeding was pending] and denied Applicant's SWMS environmental resource permit application. While Sheridan [II] was pending, DEP issued a notice of intent in March of 1999 to further modify the specific conditions of the 1995 Original Permit. These modifications would allow Applicant to construct and operate a boat travel lift at a new location within the Marina and to install flushing culverts in lieu of the previous requirement of a flushing channel between the north and middle Marina canals. [The modification for the boat lift would allow the construction and operation of a boat lift at the eastern end of the north canal.] These 1999 modifications to the Original Permit were timely challenged by Petitioner and the matter was referred to DOAH, resulting in the formal administrative proceeding now on review in this Department Final Order. Sheridan vs. Deep Lagoon Boat Club, Ltd., et al., OGC Case No. 99-0619, DOAH Case No. 99-2234, (DEP March 6, 2000). As stated in the quote above, following its purchase of the marina, the Boat Club conducted contamination and maintenance dredging of the marina's canals. This dredging had been preliminarily authorized by DEP, but DEP's preliminary action was challenged. The result of the litigation was that the permit for the dredging was disapproved, a result too late for the opponents of the process because the dredging had been undertaken and completed while the litigation wended its way through state agencies and the court. In the meantime, the boats stored on the north peninsula were removed to make way for the dredged materials. When the dredging was completed, dry boat storage resumed on the north peninsula. During the Sheridan II proceedings, the Final Order in Sheridan III was rendered. It accepted the recommendation of the administrative law judge that, with four changes, the modifications that would allow the boat travel lift at the eastern end of the north canal and the flushing culverts be granted. The recommendation was predicated on findings related to and conclusions that any adverse impacts on water quality would be negligible and that impacts to the manatee would be minimal or that projections of significant impacts were speculative. These findings and conclusions were adopted and accepted by DEP in the Sheridan III Final Order. While the administrative process in Sheridan III proceeded toward its culmination with the issuance of a final order in March of 2000, Sheridan II was under appeal in the Second District Court of Appeal. Almost a year after the Sheridan III Final Order, the Court rendered an opinion in Sheridan II. Rehearing in the Sheridan II appellate proceeding was denied on April 6, 2001. The Court affirmed DEP's adoption of the conclusion that the Boat Club failed to provide reasonable assurance that the secondary impacts of the operation of the proposed SWMS would not violate water quality standards and would not adversely impact the West Indian Manatee. While the appellate litigation in Sheridan II was pending, the 1989 dredge and fill permit expired. In order to upgrade the Marina, therefore, the Boat Club was required to re-apply to DEP for an Environmental Resource Permit, a type of permit that succeeded the type of permit (the dredge and fill permit) issued by DEP in 1989. This most recent Environmental Resource Permit application is the subject of this proceeding. The ERP Subject to this Proceeding The Boat Club application for the new Environmental Resource Permit ("ERP") was received on August 24, 2001. The following January 22, 2003, approximately one year and five months after the filing of the ERP application, DEP issued a "Consolidated Environmental Resource Permit and Sovereign Submerged Lands Authorization" (the "Permit/Authorization"). The Permit/Authorization governs the Boat Club's proposed dredge and fill activity, its proposed stormwater and surface water management plan and authorization of sovereign submerged land use. The permitted activity is described in DEP Permit/Authorization No. 36-0128502-008 as follows: The project is to upgrade an existing 445 slip commercial marina. Upon completion, the marina will accommodate 485 slips (129 wet slips and 356 dry slips) 40 of which shall be occupied by sailboats or left unoccupied. This shall include the construction of 1,693 lf (2,257 sq. ft.) vertical retaining wall in the north canal landward of mean high water (MHW) and existing mangroves. The construction of a travel lift affecting approximately 600 sq. ft. and approximately 37,369 sq. ft. of docking structure (3,529 sq. ft. of fixed docking structure and 33,840 sq. ft. of floating docking structure). The construction of two 48" grated culverts to enhance flushing, as well as, the removal of two travel lifts and approximately 10,443 sq. ft. docking structure. Further, the activity is to construct a surface water management system to serve 15.4 acres (total upland area) of the entire 24.0-acre commercial marina site. Construction of the surface water management system will include three separate and independent stormwater collection systems with associated pretreatment areas and underground vault (Infiltrator) systems for stormwater storage/treatment prior to discharge through concrete weir outfall control structures into adjacent Class III waters. Petitioners' Exhibit 15, page 3 of 20. The Parties Petitioners The three petitioners all reside in proximity to Deep Lagoon. Brenda Sheridan resides to the northeast of the marina. Her lot, owned since 1976, is on the shores of the Caloosahatchee River at Deep Lagoon. She and her husband are avid practitioners of fly fishing. In addition to fishing, Ms. Sheridan boats in Deep Lagoon, including in the north canal, where she enjoys observing wildlife, particularly manatees. A member of the Save the Manatee Club for more than 20 years, she has observed manatees in Deep Lagoon "[f]or many years" (Tr. 963) and continues to see them "all the time." Id. With the exception of calving, she has seen them "doing just about everything" (Tr. 964), including drinking fresh water off the surface of Deep Lagoon. She has participated in posting manatees signs "starting at the channel coming in from the river into Deep Lagoon . . . through the cove." (Tr. 973). She has assisted state personnel in the recovery of a manatee carcass, and has reported what she has believed to be speeding boats the many times she has seen them. She believes that the proposed permit will adversely affect her activities of fishing and observing wildlife and fervently hopes to be able to continue to "enjoy wildlife and unpolluted waters for the rest of my life and also for my grandchildren." (Tr. 979). Kevin Derheimer and Kathryn Kleist reside on Deep Lagoon Lane in Ft. Myers adjacent to the Iona Drainage Ditch immediately north of the north canal. Members of the Audubon Society, they selected the property where they built their home because it had been owned by Ms. Kleist's family, and because they "had observed wildlife, manatees, and birds from this piece of property and [so] decided to build a home there because of the proximity to wildlife" (Tr. 856), as well as its proximity to wetlands that could not be developed. They boat, kayak and fish on Deep Lagoon, and observe the abundant wildlife there especially manatees. Ms. Kleist has seen up to seven manatees at one time together in Deep Lagoon. Her observations have taken place over the last five years. She describes herself and her husband as avid observers of manatees who keep their binoculars at the ready any time they think they might have spotted a manatee in the lagoon. Ms. Kleist has a number of concerns about the proposed permit, particularly its effect on the north canal and the areas of the lagoon used by manatees observed by her over her years of residence in the area. Of major concern to her is the increase in boat traffic. Consistent with Mr. Ruff's testimony quoted in paragraph 178 below, Ms. Kleist testified that the proposal will make the marina "much larger" (Tr. 941) than it has been in her five years living in the area. (Tr. 940). When asked whether she observed the speed zones that apply to Deep Lagoon, Ms. Kleist candidly replied: Probably not all the time. Just like I don't with my car. But we attempt to pay attention to speed zones. It's not intentionally, but if you're asking me to 100 percent of the time, have I never speeded in my boat, I would say no. (Tr. 959). Respondents Respondent DEP is the state agency authorized to issue environmental resource permits for projects affecting the waters of the state under Chapter 373, Florida Statutes. It is delegated authority to issue proprietary authorizations to use sovereign submerged lands by Florida Administrative Code Rule 18- 21.0051. Deep Lagoon Boat Club, Ltd., is the owner and operator of Deep Lagoon Marina, a 24-acre marina, claimed in its proposed recommended order (adopted by DEP) to consist presently "of 50 wet slips and approximately 350 dry slips (171 boats stored inside two storage buildings and the remainder stored outside of the buildings on racks or block)." Deep Lagoon Boat Ltd.'s Proposed Recommended Order, p. 6-7. A principal of the Boat Club is Edward J. Ruff, a developer of marinas in southwest Florida. The business is a family concern as was evidenced by the presence of many members of the Ruff family at the final hearing. Mr. Ruff has had success in developing several marinas in southwest Florida. An advocate of the Clean Marina Program, Mr. Ruff attributes the success to his pursuit of development of marinas that meet Clean Marina criteria. The Boat Club has applied for Clean Marina status for the Deep Lagoon Marina, but was turned down for lack of compliance with one criterion. It does not yet have a surface water management system that has been finally approved by DEP. The Boat Club hopes that approval of the surface water management system under review will clear the way for it to be able to "fly the flag" (Tr. 312) that demonstrates its achievement of Clean Marina status. Petitioners' Challenge Petitioners raised 10 bases in their petition for denial of the Consolidated Permit/Authorization. One, found in paragraph 32.H., of the petition, concerning the application of Florida Administrative Code Rule 18-21.0045, has been waived. See p. 55 of Petitioners' Proposed Recommended Order. The remaining nine alleged in paragraph 32 of the petition are as follows: Whether Deep Lagoon Club has provided reasonable assurances of compliance with the applicable water quality standards as required by Section 373.414(1), Fla. Stat., including Florida's anti-degradation policy in Rules 62-4.242(1)9a) and Rule 62- 302.300(7), Florida's minimum standards in Rule 62-302.500, and Florida's Class III standards Rule 62.302.560. * * * Whether Deep Lagoon Club has provided reasonable assurances of compliance with the public interest criteria of Section 373.414(1)(a), Fla. Stat., . . . Whether Deep Lagoon club has provided reasonable assurances of compliance with the elimination and avoidance criteria of Section 373.414(1)(b), Fla. Stat. and SFWMD Basis of Review Section 4. Whether Deep Lagoon Club is collaterally estopped from being granted an ERP for its proposed stormwater management system due to the DEP's denial of the same proposed stormwater management system and its secondary impact on Manatees. . . . Whether Deep Lagoon Club failed to provide reasonable assurance concerning the direct impacts and secondary impacts of its proposed activities on the endangered Manatee. (Section 373.414(1)(a), Fla. Stat.; Rule 40E-4.301(1)(d)-(f); Basis of Review Section 4.2.7(a); [citation omitted]; Section 370.12(2)(m), Fla. Stat.; Fla. Admin. Code Chapter 68C-22 . . .; . . . Whether Deep Lagoon Club failed to provide reasonable assurance concerning the past, present and foreseeable cumulative impacts, especially including cumulative impacts on the endangered Manatee. . . . Whether Deep Lagoon Club has provided reasonable assurances its sovereign submerged lands application complies with the public interest criteria of Rule 18-21.004, including secondary impacts on the endangered Manatee . . . * * * Whether Deep Lagoon Club has provided reasonable assurances that its proposed activities are consistent with Florida's Coastal Zone Management Program . . . Whether Deep Lagoon Club has provided reasonable assurances of compliance with applicable standards, rules and ordinances in light of its past violations such as failing to register for sovereign land lease, dredging the marina basin without authorization, and dredging the marina basin to depths and widths greater than Florida's exempt statute authorized . . . Petition for Hearing, pp. 11-15. These bases can be grouped under three headings: the proposed stormwater management system and water quality; the impact of the Consolidated Permit/Authorization on the Endangered Manatee, and (3) other issues related to these two such as collateral estoppel and past violations. Fundamental to resolution of these issues are issues that relate to the number of boat slips at the Boat Club marina and the number of power boats the marina can accommodate. These numbers vary depending on whether marina usage is considered in terms of physical capacity, actual usage or legal limits. Physical capacity, as found above, exceeds 600 slips. Actual usage has varied over the years. The lawful number of slips depends on local development orders and permit requirements. If a permit is to be obtained from the state, then the lawful number of boat slips and power boats may be restricted, just as is proposed in the permit at issue in this case. Lawful Number of Boat Slips and Power Boats Of the 485 boat slips (129 wet slips and 356 dry slips) allowed at the marina under the Consolidated Permit/Authorization, 40 may not be used for power boats. The 40 may be used for sail boats; otherwise, they must remain unoccupied. This leaves a maximum of 445 slips at the marina that may be used for power boats. Over the years, the number of boat slips at the marina and the number to have been authorized by the various sought- after permits have varied. For example, on June 26, 1998, a Manatee Impact Review Report issued by the Bureau of Protected Species Management, then in the DEP's Division of Marine Resources, showed the marina to have 228 existing slips: 61 wet and 167 dry. The report shows that the marina had an additional 446 slips (113 wet and 333 dry) that were "[p]reviously permitted but not constructed". DEP Ex. 41, page 2 of 7. According to the report, together the existing and authorized, not-yet-constructed slips totaled 674 (174 wet and 500 dry). In the Sheridan II administrative proceeding, the administrative law judge found as follows: 26. In 1988, DEP issued a DAF ["dredge and fill" permit] to Applicant's predecessor in title for additional wet slips (as modified, the Original Permit). Due partly to the likelihood of the replacement of some older, smaller slips with larger slips, there is some uncertainty as to the precise number of wet slips that Applicant would be able to construct under the Original Permit. However, Applicant would be able to construct approximately 89-113 new wet slips . . . so as to raise its marina capacity to 150 -174 wet slips. Applicant also plans to construct 227 dry slips, so as to raise its marina capacity to 427 dry slips, and add 115,000 square feet of buildings, including a restaurant. Deep Lagoon Ex. 9D, 22 FALR 3286. The Applicant and the Department took exception to Finding of Fact No. 26 while the recommended order was under consideration by DEP. The finding was modified in DEP's Final Order so as to reduce the number of new wet slips authorized to 89 so that the total number of wet slips numbered 150. The new dry slips to be added through the permit process under review were left at 227 by the DEP Final Order so that the marina's total capacity for dry slips, if the permit were granted, remained as the ALJ had found, at 427. See Id., at 22 FALR 3264. In the Sheridan II administrative hearing, Mr. Uhle, counsel for the Boat Club, made the following statement: "D.R.I. actually authorized more wet slips and more dry slips. But that's if the amendment is approved, that's what will be authorized." Deep Lagoon Ex. 43, p. 30. In fact, a DRI Amendment (presumably the one to which Mr. Uhle referred) was approved subsequent to the administrative hearing in Sheridan II. The Deep Lagoon Development of Regional Impact Development ("DRI") Order had been adopted on March 23, 1987. At the behest of the Boat Club by the filing of a Notice of Proposed Change on August 10, 1998, the DRI Development Order was amended for a second time. The amendment was adopted on June 7, 1999, a month or so after the administrative hearing in Sheridan II. The "Second Development Order Amendment for Deep Lagoon Marina, A Development of Regional Impact" (the "Current DRI Order") employs a "strike-through and underline format" (Boat Club Exhibit 8, Attachment 18, p. 2 of 17), that reveals both the amendment requested by the Boat Club and the DRI Development Order as it existed prior to the second amendment. The Current DRI Order authorizes "150 permanent wet slips; of which 30 will be reserved only for temporary moorings; 115,000 square feet of dry storage (427 slips)" (Id.) The Current DRI Order thus sets the number of boat slips at the marina as 150 wet slips and 427 dry slips. The Current DRI Order is consistent with the conclusion of DEP in its Final Order in Sheridan II: the legal capacity of the marina, were the permit applied for there to be granted, would be 150 wet slips and 427 dry slips for a total of 577 slips, wet and dry. This capacity was not achieved through permitting, however, because DEP accepted the recommendation of the administrative law judge that the permits applied for in Sheridan II be denied. The denials were based, at least in part, because DEP "declined to reject the ALJ's mixed statements of law and fact concluding that increased boating capacity and other Marina expansion activities authorized in the Original Permit constituted adverse secondary impacts of the proposed SWMS to water quality and to manatees and their habitat." Deep Lagoon Ex. 9D, 22 FALR at 3277. Water Quality and Surface Water Management The Boat Club proposes to construct a stormwater management system for the entire 15.4 acres of uplands at the marina site. Such a system is badly needed if the marina is to operate with environmental integrity. For the most part, any surface water that is generated presently on the south peninsula hits the pavement or the buildings and then runs off into the canals. On the north, runoff sheet flows across the non- vegetated areas and discharges directly into the canal systems. "A person proposing to construct or alter a stormwater management system . . . shall apply to the governing board or the department for a permit authorizing such construction or alteration." Section 373.413(2). Existing ambient water quality in Deep Lagoon does not meet water quality standards. Data collected in May of 2002, "showed exceedances . . . of total coliform . . . of dissolved oxygen and . . . of copper, cadmium and zinc." (Tr. 560). "If the applicant is unable to meet water quality standards because existing ambient water quality does not meet standards, the . . . department shall consider mitigation measures proposed by . . . the applicant that cause net improvement of the water quality in the receiving body of water for those parameters which do not meet standards." Section 373.414(1)(b)(3). Construction of the surface water management system will include three separate and independent stormwater collection systems, associated dry pretreatment areas, and an underground vault/infiltrator system for storage and treatment of stormwater prior to discharge through concrete weir outfall control structures into the adjacent Class III waters. The system proposed in this proceeding retains the components of the design that failed to win approval in Sheridan II, and it enhances them with additional measures designed to provide net improvement in water quality in the receiving body of water. Under the proposed system, any water flowing from a rain event is routed into above-ground pretreatment areas, an enhancement to the original system. Once the water in these detention systems reaches a certain level, it flows into drainage structures. The structures transport the water below ground into a series of pipes connected to underground infiltrator storage treatment areas. The underground infiltrator drainage structures, constructed over crushed stone, were not designed specifically as a retention system. Nonetheless, they have the ability to remove water through ex-filtration into the ground. Chambers will be placed throughout the marina property, including under buildings and parking surfaces, and under some pathways. Their primary function is to detain waters and, through a settling process, treat it. The number of infiltrators provided in the proposed system is increased over the prior system, another enhancement. After detention in the underground system, the water is discharged through three outfalls, one for each of three independent drainage areas. The proposed dry pretreatment areas increase total stormwater storage capacity over the prior system by roughly 18,000 cubic feet, a 30-40 percent increase of storage over the prior design. With the prior system, there could have been discharge from parking areas into the canals during storms. The proposed system is designed so that all the runoff from the uplands is captured by the system. The proposed Marina Management Plan (the "Plan"), another enhancement, will add extra safeguards to eliminate some pollutants. The Plan provides a maintenance program to be carried out by a designated Environment Compliance Officer. Maintenance includes regular inspection of the chambers, themselves, inspections of the outfall structures, and an annual reporting to DEP as to the status of the storage/treatment system. The surface water management system also incorporates three "closed loop" recycling systems, one for each of the two designated boat wash-down areas and a third, located in the maintenance and service area, added as an enhancement to the prior system. The three recycling systems each consist of a concrete containment area with a drain. The water flows into the drain and is pumped up into a closed loop treatment system. There the water is pumped through a purifying device, separating contaminants and byproducts. The clean water is then reused for future wash downs. In the prior system, overflow, during an extreme storm event, for example, would flow into the surface water management system. Under the proposed plan, overflow from the recycling systems discharges directly into the municipal sewage system that will serve the site, another enhancement over the previous system. The proposed permit requires the closed loop recycling systems to be inspected by a Florida-registered professional engineer on an annual basis. The water discharged from the discharge structure will meet Class III standards. The system also complies with design requirements for discharge into Outstanding Florida Waters. The surface water management design incorporates best management practices to eliminate erosion or water quality problems during construction of the project. If done in compliance with permit requirements, construction and operation of the proposed stormwater management system will be in compliance with the Southwest Florida Water Management District's Basis for Review. These requirements together with the Marina Management Plan will improve the quality of the water leaving the site. There will be a net improvement in water quality for all parameters in the marina's receiving waters that currently do not meet standards. The treated water leaving the site will not cause parameters currently within standards to violate those standards. The contamination and maintenance dredging project performed by the Boat Club in 1999, appears to have improved water quality based on a comparison between 1997 pre-dredging water quality data, and the 2002 post-dredging water quality. Jack Wu, a professional engineer and DEP's expert in "coastal engineering, hydrographic impacts of submerged lands and environmental resource permit projects" (Tr. 750), performed a technical review of the marina canals and the proposed projected in accordance with the Basis of Review. He considered the structural design, size, and configuration of the proposed docking system, the flushing and mixing study, tidal data, and water quality data. Mr. Wu's testimony establishes that the proposed flushing culverts will increase circulation and eventually reduce the flushing time of the canals. Jack Myers, DEP's stormwater system design expert testified that the proposed surface water management system would not cause adverse secondary impacts to water resources of the District according to his assessment. Mr. Myers' assessment of the secondary impacts, however, did not include impacts to manatees. The Endangered Manatee Manatees are listed as an endangered species under the federal Endangered Species Act of 1973 (ESA)(16 U.S.C. 1531, et seq.), and under Florida law (Florida Administrative Code Rule 68A-27.003(1)(a)(31). In view of their status as endangered and as a Florida wildlife resource, manatees have undergone extensive study by many including the Florida Marine Research Institute in the Florida Fish and Wildlife Conservation Commission. Among these studies is the Special Study, conducted as the result of a settlement of litigation and released in November of 2002. Paragraphs 91-129 are derived from the Special Study, a copy of which appears in the record as Petitioners' Exhibit 20. The Florida Manatee The Florida manatee (Trichechus manatus latirostirs) is one of two subspecies of the West Indian manatee (T. manatus). Florida manatees inhabit the southeastern United States, primarily occupying the marine, estuarine, coastal, and freshwater inland waters of Florida. Manatees are herbivorous marine mammals. Manatees are not typically gregarious although mothers and calves travel in pairs and, on occasion, manatees travel in mating herds. Otherwise, for the most part, they are solitary although they may aggregate in areas with resources essential to the well-being of the population. These resources include warm water, fresh water, quiet resting areas, and areas with aquatic vegetation (marine and freshwater). Like most large mammals, manatees have a potentially long life-span, mature slowly, are slow to reproduce, and have a high parental investment in their offspring. Threats to the manatee population have their origin both in nature and in the activities of human beings. Potentially catastrophic, naturally occurring threats to manatees include hurricanes, red tide events and disease, and exposure to cold temperatures. To combat cold temperature exposure, manatees rely on a network of warm-water sites in eastern and southwestern Florida, as refuge during the cold season. Tampa Bay is a prime site of warm water refuge because of the number of power plants in the area. The only power plant that produces a manatee aggregation site between Tampa Bay and eastern Florida is the FP&L power plant up river from Deep Lagoon. Continued high counts of manatees at sites near power plants in southwestern Florida highlight the manatees' dependence on this network. Manatees feed on a variety of marine, freshwater, and terrestrial plants. Common forage species include shoal grass, manatee grass, turtle grass, tape grass, and widgeon grass. Manatees are reported to feed on seagrass plants both above and below the sediment. It has been theorized that manatees use fresh water for regulation of body temperature. They obtain fresh water from the plants they consume and are able to maintain their body water balance in salt water systems without drinking fresh water. Nonetheless, manatees are attracted to fresh water sources, especially in areas of high or fluctuating salinity like the Caloosahatchee. In estuarine waters such as Deep Lagoon, where fresh water floats on the top of saltier water, manatees have been observed with their mouths open at the surface drinking fresh water. Warm-water refuges play an important role in defining manatee movements between Shell Point and the Edison Bridge. The warm water refuge at the FPL power plant is classified in the Special Study as a Primary warm-water site. A secondary warm- water site along the River is at the Franklin Lock and Dam. Another secondary warm-water site in the area is in the canals of the Matlacha Isles at the northern end of Matlacha Pass. An old quarry pit in Ten-Mile Canal, Mullock Creek, is another site near Deep Lagoon where manatees aggregate because of warm water. In 2001, FP&L re-powered its plant from oil to natural gas. This reduced its warm water effluent. To compensate for the reduction and to provide manatee habitat, FP&L installed "donkey boilers" in January of 2002. The discharge in January of 2002, was more than one degree Celsius cooler than it had been in January of 2000, but the average January temperature of the FP&L discharge remained more than two degrees Celsius warmer than the water at the Franklin Lock. The single greatest cause of manatees' human-related mortality (referred to in the Special Study as "anthropogenic") is collisions with watercrafts. With regard to "anthropogenic" threats to manatees, the study, in part, reported the following: From 1976-2001, watercraft collisions accounted for approximately 25% of all manatee deaths and are the single greatest cause of human-related mortality (FWC unpublished data). In 2001 there were over 943,000 registered vessels in Florida (citation omitted). Given that about 97% of registrations are for recreational watercraft (citation omitted), it can be expected that there will be a continued increase in recreational vessels plying the waterways of Florida due to an increase in the human population. In addition to the expected increase in boat numbers over the next 25 years, other factors may act synergistically to increase the risk of fatal collision between manatees and watercraft. Relatively new modifications to the design of vessel hulls and engines allow boats to travel at higher speeds in shallower waters (citation omitted), thus threatening manatees and scarring seagrass beds. Boater compliance with existing slow speed zones is inconsistent (citation omitted). Sub-lethal effects of increased vessel traffic on manatees and a growing human population in the nearshore waters create more risk to manatees. Most adult manatee carcasses bear scars from previous boat strikes, and the healed, skeletal fractures of some indicate that they had survived previous traumatic impacts (citation omitted). Of over 1000 living individuals in the manatee photo-identification database (citation omitted), 97% had scar patterns from multiple boat strikes (citation omitted). It should be noted that the photo- identification database contains only animals with scars or other identifiable features. Non-lethal injuries may reduce the breeding success of wounded females and may permanently remove some animals from the breeding population (citation omitted). Vessel traffic and recreational activities that disturb manatees may cause them to leave preferred habitats and may alter biologically important behaviors such as feeding, suckling, or resting (citation omitted). Other threats from human activities include entanglement in fishing gear or debris; entrapment or crushing in water-control structures, locks and pipes; exposure to contaminants; and incidental ingestion of debris (citation omitted). Indirect effects from increased vessel traffic include increased water turbidity from wake action and decline of seagrass beds due to scarring by propellers (citation omitted). Petitioners' Exhibit 20, pp. 3-4. Essential Habitat for the Manatee Essential habitat for manatees, referred to in the Special Study as "places" (see id., p. 17), are areas frequented by manatees for extended time periods. These manatee places contain key habitat for manatee feeding, resting, and thermoregulation. In addition to the warm water aggregation places, the FWC's field staff has verified other places in the Caloosahatchee River area important to manatees. These secondary sites are important because they either contain fresh water or seagrass beds, aid in manatee thermoregulation, or are areas of minimal disturbance. Manatees are frequently seen in these important secondary sites during rapid cooling spells that do not greatly drop the ambient water temperature. Id. These important secondary sites are: Eight Lakes (deep canal lakes with warm water and sediments in SW Cape Coral); Chiquita Canal (freshwater source with access to Eight Lakes area); Bimini Basin (may be used for resting); Shell Point Village Lagoon (may have fresh water); Punta Rassa (seagrass beds-feeding aggregation); Beautiful Island (possible feeding site); Downtown Fort Myers Basins (presumably for fresh water discharged from hoses); Deep Lagoon (fresh water, resting, or warm water); Iona Cove (feeding); and Billy Creek (sediments retain heat). Deep Lagoon has been denominated a "minor aggregation site." Manatee Corridors Manatee "corridors" are areas visited regularly by manatees for brief times as they travel from place to place. The FWC has used telemetry data of manatees to model manatee corridors and manatee places. The Caloosahatchee River is a major manatee travel corridor because of the warm water discharged by the FP&L plant. The FP&L refuge attracts one of the largest wintering aggregations of manatees in Florida, with as many as 469 manatees having been counted in Lee County during the winter. In January 2001, as many as 434 manatees were counted in one day at the FP&L refuge. Manatees in the Caloosahatchee River generally travel not far from the shoreline, but they have also been observed to travel in the River's channels. Manatees also cross the Caloosahatchee River between Deep Lagoon and the Redfish Point area where the river narrows to 1,000 meters, and at Shell Point where the river narrows to 710 meters. Redfish Point lies across the river from Deep Lagoon. Manatees frequently travel between Redfish Point and Deep Lagoon, thereby crossing the main boat channel of the river. The FWC has identified this narrow part of the river between Redfish Point and Deep Lagoon as both a manatee travel "corridor" and as a heavy boat vessel travel corridor. Manatee crossings of the river also occur at Shell Point where the River narrows to 710 feet. Shell Point is the mouth of the river area where the river flows into San Carlos Bay. The FWC has identified the Shell Point area as a manatee travel corridor, and as the most heavily used boat vessel travel corridor. The 1998 Gorzelany report recorded an average of five boats per minute passing the Shell Point area. Just to the west of Shell Point, the boat channel in eastern San Carlos Bay is known as the "Miserable Mile." The Shell Point and Miserable Mile area likely represent the highest risk areas for watercraft collisions with manatees. Manatee Population The exact number of Florida manatees is unknown. Manatees are difficult to count because they are often in areas of poor water quality, and their behavior, such as resting on the bottom of a deep canal, can make them difficult to see. Aerial surveys and ground counts (statewide synoptic survey) have been conducted by the state in most years since 1991. There are four regional sub-populations of the Florida Manatee, these being in the Northwest Region, the Upper St. Johns River Region, the Atlantic Region, and the Southwest Region. The great bulk of the Florida population lives in the Atlantic and Southwest Regions. The sub-populations of the Manatees in those two regions account for substantially more than 80 percent of the total Florida manatee population with roughly half of the two in each region. The Southwest Region of the West Indian Manatee consists of the coastal counties from Pasco County south along the Gulf of Mexico to Whitewater Bay in Monroe County (including Lee County), and the inland counties of DeSoto, Glades, and Hendry Counties. The Southwest Region population of the Florida manatee constitutes approximately 42 percent of the total Florida manatee population. The adult survival rates in the Southwest Region are substantially lower than the survival rates in all of the other manatee regions in the state. The average age at death of manatees in the Southwest Region is significantly lower than in other regions of the state and statewide. Of the four Florida sub-populations, there is less data available for the Southwest population. "[A] priority [has been] placed on catching up to gather the necessary amount of data to better evaluate [the] status of the southwestern population." (Tr. 516-517). Nonetheless, both FWC and the U.S. Fish and Wildlife Service (FWS) have developed manatee population models, that are both sound and comprehensive. The two agree about the status of the Southwest Region population of the Florida manatee and its immediate future as explained at hearing by Dr. Bruce Ackerman, an expert in marine mammal biology, manatee population modeling, and manatee aerial surveys: "The two models were written to answer somewhat different questions, but an area that they agree on is that the southwest population is likely to be declining now, whether a little or a lot, is not so clear, but likely to be declining at this time and in the near future." (Tr. 923). The FWC's Florida Manatee Recovery Plan contains three benchmark criteria for each of the four manatee regions: average annual adult survival rate of 94 percent, average annual reproduction (at least 40 percent of adult females with calves during the winter), and the average annual rate of population growth is equal to or greater than zero. The Southwest Region manatee population is currently failing to meet the Florida Manatee Recovery Plan goal criteria. Even in the absence of any water-craft related mortalities (incidental takes), the growth rate of the Southwest Region manatee population over the next 20 years is expected to be negative. In the Southwest Region, there is no excess manatee population growth and no net productivity which can be allocated to incidental takes. In the absence of any water-crafted related manatee moralities in the Southwest Region, the probability of recovery of the Southwest Region manatee population in the next 100 years is 63 percent. If current Southwest Region watercraft-related manatee mortality trend continues, there is a zero percent chance of the recovery of the Southwest Region manatee population. Natural Threats to Manatees Manatee populations are threatened by natural causes as well as causes whose origin is human activity. The fatal and non-fatal natural threats to manatees include cold temperatures, hurricanes, red tide (Karenia brevis) events, and disease. Manatee carcasses with evidence of cold- stress show reduced gastrointestinal tract activity, a condition that can reduce an animal's buoyance. Juveniles and sub-adults are the most vulnerable to cold-stress death. Manatees on Florida's west coast are frequently exposed to brevetoxin, a potent neurotoxin, during red tide events. Manatees are exposed to brevetoxin through inhalation and ingestion. There were 75 manatee fatalities in the Southwest Region due to red tide recently. Watercraft-Related Mortality Types of Fatal Injuries The Florida Marine Research Institute conducted an analysis of watercraft-related mortality of manatees in Florida covering the period 1979 to 1991. Its abstract sums up the analysis as follows: From 1974 to 1991, the annual number of manatee (Trichechus manatus latirostris) deaths increased. The most frequent cause of death from human activity is collision with watercraft. Scars and wounds from propellers are common. A total of 1,376 sets of fatal or healed wounds was measured on 628 dead manatees recovered from 1979 through 1991. Collisions with watercraft caused 406 of these deaths. Of the 406 deaths, propeller cuts caused 158 (39%); impact injuries (no propeller cuts) caused 224 (55%); propeller cuts and impact injuries, either of which would have been fatal, caused 16 (4%); and unidentified specifics of the collisions caused 8 (2%). Fatal cuts were usually larger (longer) than healed wounds. Many animals survived several boat collisions; one manatee had 22 separate patterns of propeller cuts. The mean length [formula omitted] of the longest fatal cut from a propeller indicated that death was most often caused by a direct-drive watercraft. In contrast, fatal-impact injuries may have resulted from fast-moving watercraft of many sizes and types. Impact injuries killed more manatees than propeller cuts and increased in proportion with time. Impact often resulted in massive internal injuries with only minor surface abrasions. Only 2% of the propeller strikes were to the head, but 98% were to the dorsum. In addition, nearly 90% of the scar patterns were along the head-to-tail axis, indicating manatees were moving in response to an oncoming boat when struck. Changes in watercraft design may increase the frequency of operation of boats in shallow water. This increases the probability of collisions with manatees. Petitioners' Exhibit 26, pp. 259-260. The location of scars and wounds from propellers ranged from the head to the tail of manatees: Head (2%), Thorax (26%), Mid dorsal (body)(17%), Abdomen (36%), Tail (19%). Watercraft collision with manatees are common. Even U.S. Coast Guard and the FWC marine patrol boats have struck manatees. Mortality Data While the FWC's manatee mortality data are deemed to be reliable, the FWC does not document all watercraft-related manatee fatalities. It is, of course, not possible to know how many manatee carcasses escape observation and are not recovered. Even estimation of such numbers has difficulties. But scientifically, it is generally accepted that there is an undercount of manatee carcasses. It is known, for example, that in cases of manatee perinatal (dependent calf) deaths, carcasses are frequently not recovered. No recoveries in such cases are due to a number of factors: the small size of the carcass, rapid decomposition, and presence of scavengers. The manatee deaths listed by the FWC as having an undetermined cause of death could be watercraft-related deaths. A perinatal death, moreover, could be the direct result of a watercraft-related death of the mother. Watercraft-related manatee injuries are not limited to power boats. They may also be caused by sailboats. A significant number of sailboats have shaft driven inboard motors with a rudder that functions as a skeg (a projection that is the after part of the keel or an extension upon which the rudderpost is mounted). Collisions between skegs and manatees cause sub- lethal and lethal injuries to manatees. Statewide Mortality Rate The most frequent cause of manatee death that is avoidable is watercraft collision. Statewide, the watercraft- related mortality of manatees is 24.5 percent for the time period January 1974, to December 2002, the highest single cause of manatee deaths. Lee County Mortality Rate Among counties, Lee County has the second highest level of watercraft-related deaths in Florida, with 163 reported between January 1974, and December 2002. From 1975 through 1993, the annual watercraft-related manatee deaths in Lee County were less than 10 per year. During the nine years from 1994 to 2002, there were 109 watercraft-related manatee deaths in Lee County, an average of 12.1 per year. In 1999, the watercraft-related deaths were 10 in Lee County. There were 13 in 2000, 23 in 2001, and 13 in 2002. The first six months of 2003, through June 10, have seen six watercraft-related deaths of manatees in Lee County. The 23 manatees to have died from watercraft-related injuries in Lee County in 2001, accounted for 45 percent of the total number of manatee deaths in Lee county for the year. Caloosahatchee River Mortality Rate For the ten years from 1976 to 1986, the number of watercraft-related manatee deaths in the Caloosahatchee River was 15, with an average annual number of such deaths being 1.5 per year. For the five years from 1988 to 1993 (no data available for 1989), the number of watercraft-related manatee deaths in the Caloosahatchee River was 13, with the average annual number of such deaths being 1.8 per year. For the seven years from 1994 to 2000, the number of watercraft-related manatee deaths in the Caloosahatchee River was 30, with the average annual number of such deaths being 4.3 per year, a substantial increase over the earlier annual numbers. From 1989 through 2001, the annual number of watercraft-related manatee deaths for the Caloosahatchee River increased by 15.1 percent per year. This rate of increase is higher than the rate of increase of such deaths in the Southwest Region manatee population (9.2%), and almost triple the rate of increase of such manatee deaths statewide (5.5%). The rate of increase of watercraft-related manatee deaths over the past 13 years in the Caloosahatchee River, moreover, is higher than: (a) the manatee death rates of all categories for the Caloosahatchee River, (b) of all watercraft- related manatee deaths in southwest Florida, and (c) of all watercraft-related manatee deaths statewide. There are a number of caveats to be considered when considering manatee death data. For example, "[I]t cannot be conclusively known where manatees are actually struck by boats." Petitioners' Exhibit 21, p. 9. A "Summary and Analysis of Manatee-related Data in Lee County, 2002" prepared by Mary Duncan of the FWC (Petitioners' Exhibit 21), elaborates: The mortality database reports carcass recovery locations, which is not necessarily where animals were struck by watercraft, or where they died. For watercraft-related manatee deaths, the precise location of where animals are struck usually cannot be verified unless reported by a witness of the incident. Carcasses may move with currents and tides, but also some injuries may not cause immediate death. Injured animals have been know to swim many miles before dying. Since there is a warm water refuge in the Orange River, at tributary off the Caloosahatchee River, it is possible that some injured animals may attempt to reach this area since it represents a safe place. Cases where death occurred several days to weeks after the trauma are considered "chronic". Some of the recent watercraft-related deaths recovered in the Orange River have been identified as chronic. Efforts are underway to make this determination on historical necropsy reports. It is possible that some animals included in the Caloosahatchee River dataset may have actually been struck outside the river system. While this analysis may provide additional information and insights, it should be recognized that most cases do not have evidence of chronic injuries-but the carcass location of those cases cannot [be] assumed to represent the impact site. Petitioners' Exhibit 21, pp. 9-10. Because of these caveats, Ms. Duncan's analysis posits, "[i]t is difficult to draw conclusions on relative risks to manatees from vessels with death data alone." Her report reaches these conclusions, There appears to be an intersection of high boat use and high manatee use at the . . . mouth of the Caloosahatchee River and San Carlos Bay, commonly called the Miserable Mile area (reference omitted). This area represents the highest risk area for boat/manatee collisions. Boating studies indicate that vessel traffic is higher during the spring and summer, with the Miserable Mile area of San Carlos Bay being the highest use area. Miserable Mile is also identified as the highest vessel traffic area in Lee County in a 1998 boating study by Mote Marine Laboratory. Manatee aerial survey data confirm higher manatee use in Miserable Mile area and other parts of Lee County outside of the Caloosahatchee River system during the spring and summer. This is also confirmed by a higher number of watercraft deaths in these areas during the same time of year. Id., at 11. Ms. Duncan's report summarizes its conclusions drawn from the analysis of manatee-related data in Lee County: Existing population models now being developed typically assume that the level of threat will remain the same, since it is difficult to factor in projected threat increases. However, it is likely that threats are increasing and will continue to increase, such as increasing boat traffic and reduced foraging resources from increased coastal development. Such factors are likely to influence reproductive success and mortality rates. On a statewide basis, the continued high level of manatee deaths raise concern about the ability of the population to grow or at least remain stable. (Citation omitted.) Lee County currently ranks second in watercraft-related deaths and second in all categories of deaths statewide, suggesting that this county's waters provide a crucial habitat for manatees. Previous offsetting measures recommended during the permit review process do not appear to have offset the impacts of increasing boat traffic. Speed zones alone do not offset all adverse impacts to manatees from increased boat traffic. Long term comprehensive planning documents, such as a boat facility siting plans and manatee protection plans, are also needed to place marinas where they are least likely to increase risks to manatees. These types of conservation measures are needed to reduce the number of human-related manatee deaths, which will reduce overall manatee mortality. Id., at 13. Speed Zones and Boating Restrictions In 1989, manatee speed zones were implemented in Lee County. The steady increase in the annual number of watercraft- related manatee deaths in the Caloosahatchee River since then, and the dramatic increase in the annual rate of watercraft- related deaths in the River during the recent seven-year time period from 1994 to 2000 demonstrate, as is generally accepted and as concluded by Ms. Duncan, that speed zones alone do not offset adverse impacts to manatees from increases in boat traffic. This increase has occurred despite many features of boating restrictions in the area. Primary features of the Lee County speed zone, for example, are a one-quarter mile slowspeed shoreline buffer on either side of the intercoastal waterway channel from the mouth of the River to the U.S. 41 Bridge, and slow speed outside most of the intercoastal waterway channel from the Edison Bridge to the railroad trestle. The State-mandated manatee protection speed zones administered by FWC's Bureau of Protected Species Management under Florida Administrative Code Rule 68C-22.005, impose a year- round one-quarter mile slow speed zone for the entire shoreline of the Caloosahatchee River to the Edison bridges. East of the Edison bridges there is a slow speed zone outside of the marked channel all year, and a 25 mph maximum speed in the channel. East of the railroad trestle near Beautiful Island to east of the I-75 bridge crossing, in the area that includes the FP&L power plant, there is an idle speed zone imposed outside the channel all year, and an idle speed zone in the channel from November 15 through March 31. There is also an idle speed zone in the Orange River all year. Lee County's regulations, pursuant to its Ordinance No. 02-14, adopted on March 26, 2002, restrict boat speed within 500 feet offshore from all beaches, and within 500 feet from any water-oriented structures, such as docks, to idle speed. The FWC rules at Florida Administrative Code Rule 68C- 22.002(7), define "slow speed" as "the speed at which a vessel proceeds when it is fully off plane and completely settled into the water." The definition also states, "This required level of protection for the safety of vessels and vessel operators is also intended to provide adequate protection for manatees and is therefore adopted because of its familiarity to vessel operators." The State defines a slow speed zone as "an area where vessels may not be operated at greater than Slow Speed." Fla. Admin. Code R. 68C-22.002(8). The County's Ordinance 02-14 describes "idle speed" as: the lowest speed at which a vessel can operate and maintain steering control. The actual speed will depend upon the design of the vessel and on the vessels load, wind direction and speed, and the sea conditions. Generally, it will be between 1 and 3 miles per hour for outboard and inboard/outboard vessels, between 2 and 5 miles per hour for fixed shaft/rudder vessels. Boat Club Ex. 20 at Section Three. This definition is substantially the same as the State's definition. Marine signs in Deep Lagoon include two idle speed County ordinance signs. One is at the entrance to the central and south canals; another is at the entrance channel into Deep Lagoon and the River, inside the one-quarter mile State manatee speed zone. The second sign lets boaters know they are entering the County idle speed zone from the slow speed zone. There is also a slow speed sign for the boaters leaving the Deep Lagoon channel. It lets them know they are leaving the idle speed zone and entering the State's slow speed zone. The State, Lee County Sheriff, and Lee County municipalities participate in enforcing the State speed zones in the Caloosahatchee River. The Lee County Sheriff and the municipalities, through a memorandum of understanding, enforce the Lee County Ordinance if there is not a more restrictive ordinance in the municipality. On July 11, 2002, the Lee County Sheriff enacted a "zero tolerance" policy. It directs its marine unit to no longer issue warnings. Every stop for violation of a speed restriction is ticketed. The cost of the tickets ranges from $50 to $75. It is too soon, however, to tell what effect the policy is having on protection of manatees. Funding for Lee County marine patrol officers has increased recently. In February 2003, local law enforcement entities created a Manatee Task Force in order to better coordinate manatee protection efforts within Lee County. Once or twice per month, the U.S. Fish and Wildlife Service selects an area in Lee County for a heavy patrol known as a "wolf pack." (Tr. 426). The wolf pack consists of "three to four boats and eight or more officers". (Tr. 427). It concentrates in one area. Lee County also maintains displays of the county's Boater Guide at all local boat ramps showing the State and County speed zones, with a more detailed inset of the area where the boat ramp is located. Another education effort consisted of the mailing of a Boater's Guide that detailed manatee protection zones to about 40,000 registered boaters. Nonetheless, there are channels exempt from speed zones. All manatee travel corridors and places, moreover, are not subject to speed limitations. For example, the corridor that crosses the River from Redfish Point to the mouth of Deep Lagoon is not entirely subject to speed limitations. Commercial vehicles, moreover, can apply for exemption from manatee speed zones and can be exempted if compliance would be "burdensome." (Tr. 443). Compliance with manatee speed zones by boaters, as Ms. Kleist, an advocate of manatee protection, confessed in her case, is far from exemplary. A review of vessel activity in the Special Study led to this summary: Boaters in the Caloosahatchee River behave similarly to others throughout the state (citation omitted). Vessel traffic is highest on spring weekend afternoons. Yachts, ski boats, and open fishermen are the three most common vessel types found between the Edison Bridge and Miserable Mile while Mullock Creek is dominated by open fisherman. In these areas, the most common vessel sizes range from 16-39 feet. Highest traffic densities occur at Shell Point, where the Caloosahatchee River and San Carlos Bay converge. Mullock Creek had comparatively low levels of boat traffic. Many of the boats along the lower Caloosahatchee River originate in the Cape Coral canal system and travel toward the Gulf of Mexico. The highly variable, site- specific nature of boaters' behavior and vessel compliance requires scientists and managers to treat each site individually. Compliance with speed zones ranged from 12- 77% in the Caloosahatchee with an overall compliance of 57.3%. Although the number of vessels using Mullock Creek was relatively low, compliance was 26% accompanied by a high level of blatant non-compliance. Compliance rates may not be as important as the total number of blatant violators. While Shell Point has higher compliance, it also has heavy boat traffic that yields a greater total number of blatant violators that could pose a threat to manatees than areas with lower compliance. Petitioner's Exhibit 20, at 15. The number and size of registered boats is substantially increasing. For management of the manatee, it is important to determine where and how watercraft collisions occur. Studies to date have not yet reached these determinations. Watercraft-Related Sub-Lethal Injuries Between 60 percent and 90 percent of all Florida manatees have propeller scars. Propeller scars on manatees are so common that the FWC uses propeller scars to identify manatees. Of the over 1,000 living manatees in FWC's photo-identification data base of manatees with scars or other identifiable features, 97 percent had scar patterns from more than one watercraft collision. Most adult manatee carcasses bear scars from previous boat strikes, and the healed skeletal fractures of some of these carcasses indicate they had survived previously traumatic impacts. An example of such scar patterns is manatee MSW9321. Its carcass "floating in the Caloosahatchee River just inside the mouth of Deep Lagoon" (Petitioners' Exhibit 26), was recovered by the Department of Natural Resources in May of 1993, with the assistance of Mrs. Sheridan. The manatee had ten fresh propeller wounds along its back and across its fluke, five of which penetrated its body cavity, and multiple healed and healing scars in the dorsum. There were 31 prior scars from propeller cuts. The FWC's study of 628 manatees carcasses recovered from 1979 to 1991, found that manatee carcasses with no propeller scars were rare. Many manatees have multiple sets of propeller scars from different collisions. Non-fatal propeller cuts can become contaminated wounds which can cause prolonged illness and death. Non-fatal watercraft-related injuries can damage a manatee's ability to swim. They may reduce the breeding success of wounded females, and remove some animals from the breeding population. In sum, as was found nearly four years ago by Administrative Law Judge Meale in paragraph 14 of the recommended order in Sheridan II: The rate of manatee deaths from collisions with watercraft has increased with the popularity of motorboating. Boat registrations in Lee County rose from 13,000 in 1974 to 36,000 in 1997. The potential from mitigation offered by the enactment of speed zones has been undermined by the fact that nearly half of the boaters fail to comply with the speed limits. (Petitioners' Exhibit 8, p. 9 [this exhibit contains only the odd-numbered pages of the recommended order; official recognition is taken of the order in its entirety]). As further found in the Sheridan II recommended order: "Manatee mortality from watercraft is extremely high in the immediate vicinity of Deep Lagoon, and the mortality rate has increased in recent years." Id. Manatees in Deep Lagoon Groups of manatees frequently use Deep Lagoon. The state, under the auspices of FWC and its predecessors, has made numerous aerial flight observations of manatees of Deep Lagoon. Between January 17, 1984, and December 19, 1985, there were 48 such flights. Between July 24, 1988, and November 15, 1995, 23 aerial observations were flown. Groups of manatees were observed in Deep Lagoon near the mouth of the north canal, in all portions of the north canal, and in the Cow Slough headwaters of Deep Lagoon. Manatees radio-tagged by the state have also been documented in Deep Lagoon. On May 28, 1998, photographs were taken of groups of manatees in Deep Lagoon near the mouth of the marina's north canal and in the north canal. In late May 2003, photographs were taken of manatees in the Iona Drainage District canal near the mouth of the north canal. The Boat Club has also taken video tapes on numerous times of numerous manatees (from one manatee to groups of as many as five manatees) in the north canal. Each of the three Petitioners testified that on numerous occasions they have observed numerous manatees, including manatee mating herds in Deep Lagoon, the north canal, and the Iona canal. A manatee pair was also seen one day in the Iona Canal which appeared to be a new born manatee. Manatees have been observed several times in Deep Lagoon with small calves. From April 1974, to August 2002, within Deep Lagoon itself, 13 manatee carcasses have been recovered by the state. Four of the manatee deaths were determined to be watercraft- related deaths. Five of these manatee deaths were due to natural causes other than cold stress. For three, the cause of death was notdeterminable due to decomposition. One of the deaths was perinatal. In the Caloosahatchee River just outside the mouth of Deep Lagoon, during this period of time, the FWC recovered six manatee carcasses. Three of the deaths were watercraft-related. One was perinatal. The cause of one of the deaths was undeterminable due to decomposition. Another of the deaths was verified but the carcass was not recovered, thus the cause of death of was not determined. The Opinions of Experts None of the Petitioners' manatee experts expressed the opinion that the proposed permit would have an adverse effect on the manatee. Dr. Ackerman, for example, had never seen the application and had no opinion about whether it should be granted or not. See Tr. 933. But two of Petitioners' experts expressed opinions either that the addition of watercraft into any river system that constitutes manatee habitat poses a risk of collisions between boats and manatees or that adding boats to the Caloosahatchee River system poses a threat to the manatee unless there is some other accommodation for manatee protection. Sara Lynn McDonald, a marine biologist with FWC's Florida Marine Institute and an expert in marine mammal biology, wrote the majority of the report for the Special Study. When asked her opinion concerning whether an increase in boat traffic on the Caloosahatchee would increase the possibility of water crafts colliding with manatees, she answered, "Yes, I believe that in any system an increase in vessel traffic would increase risk of harmful collisions with motor boats." (Tr. 898). Ms. McDonald was asked on cross-examination whether she believed that speed zones are an effective measure to prevent collisions between manatees and water craft, she answered, "I think they can be." (Tr. 913). Dr. Bruce Ackerman, an expert in marine mammal biology, manatee population modeling, and manatee aerial surveys, was also called by Petitioners. Dr. Ackerman testified that the between 1974 and 1991, boat registrations in Florida trended upward and so did manatee fatalities from water craft collisions. Both trends have continued since 1991. His opinion was that "all other things being equal, adding more boats into [the Caloosahatchee River] system would increase the risk to manatees." (Tr. 923). On cross-examination, Dr. Ackerman went so far as to agree that speed zones show promise for the protection of manatees. Education, required by the state now of new boaters, in his opinion "helps somewhat." (Tr. 930). Mr. Pitchford, like Ms. McDonald and Dr. Ackerman, is an employee of FWC's Florida Marine Institute. He manages the State's Marine Mammal Pathobiology Lab where manatee necropsies for cause of death is determined. He offered testimony about the causes of deaths of manatees and related issues, but did not express an opinion at hearing, just as Petitioners' other two manatee experts, on whether the Boat Club's application should be granted or not. In contrast to the three experts who testified at the behest of Petitioners, two experts called by the Boat Club opined that there would be no adverse impact to manatees if the Boat Club's application were granted in the form preliminarily approved by the Department. Tom Logan, an expert in wildlife biology, whose specialty is in "endangered species management" (Tr. 484), opined that the project will not have an adverse affect on the manatee or its habitat. Mr. Logan offered this opinion on the basis of information he had examined and because, "the level of use that will be there with the proposed marina in place relative to what has been there in the past . . . will not result in anything increased or additive in the way of activity in the water that manatees are using . . . ." (Tr. 491). In other words, there will be no increase in power boats or other watercraft (sailboats with skegs, for example) in the Caloosahatchee River as the result of the proposed permit and therefore, granting the permit would have no adverse impact on manatees. Furthermore, Mr. Logan testified that manatee management protection programs combining speed zones, enforcement of speed limitations and education, can assist in the protection of manatees particularly in marina areas where manatees tend to congregate or visit. The speed zones in Lee County (in place of a considerable number of years), coupled with a "zero tolerance" enforcement policy in place since July of 2002, appeared to him to be working. (Tr. 491). Ms. Mary Duncan, a state Environmental Specialist III and FWC's Bureau of Protected Species Management's coordinator of its mortality database, was accepted as an expert in "potential impacts to manatees from development." (Tr. 777). At the time of hearing, she had conducted permit reviews for the bureau for 11 1/2 years, the time in which the bureau has been a part of the Department of Natural Resources, the Department of Environmental Regulation, the Department of Environmental Protection and the Florida Fish and Wildlife Conservation Commission. She has a "Bachelor's in biology with a minor in chemistry" (Tr. 775), and prior to the hearing in this case had testified four times in judicial or administrative proceedings on potential impact of manatees from development. Ms. Duncan has been involved with Deep Lagoon Marina permitting since "about 1994." (Tr. 777). In 1998, for example, she prepared a Manatee Impact Review Report for the Deep Lagoon Marina permit modification that involved the stormwater permit application and "the allowance of liveaboards, the relocation of the travel lift ramp to the north canal, and a redesign of the proposed cross connection between the north canal and the main basin." DEP Ex. 41. Her review described the project as in "an area of relatively high manatee use in Lee County, based on aerial survey and mortality data . . . [where the power plant] effluent attracts one of the largest wintering aggregations of manatees in Florida." Id. Her report further noted: Despite some existing manatee protection measures such as speed zones, watercraft- related manatee mortality trend is continuing to increase within the Caloosahatchee River. It is unknown whether the continuing deaths are a result of inadequate speed zones, inadequate posting of speed zones, inadequate enforcement of speed zones, and/or the cumulative impact from years of adding boats to the system. It is probable that many or all of these factors are involved. Id. In the historical information section of the report, Ms. Duncan showed the project to have 228 existing slips (61 wet, 167 dry) with previously permitted but not constructed slip at 446 (113 wet and 333 dry) for a total of 674 slips (174 wet, 500 dry). In a section entitled "Cumulative Impacts," the report found: This project is expected to add a significant number of boats to this system, significantly increase the level of boat traffic, and change boat traffic patterns in the study area. The vessels from this project are expected to produce significant adverse impacts to manatees that use the Deep Lagoon in the immediate vicinity of the project as well as in the boater's sphere of influence of the project. Secondary adverse impacts include lethal and sublethal watercraft- related injuries, disturbance contributing to stress, and alteration of natural behaviors. Id. Numbers of recommendations were made in the report as conditions for approval including that "boat launching from the uplands be prohibited along the shoreline of the North Canal" (id., page 5 of 7), and that "[a]fter construction of the dry storage barns, storage of boats on trailer or open dry storage racks shall be prohibited." Id., page 6 of 7. On March 1, 1999, Ms. Duncan authored a memorandum through which the Bureau of Species Protection Management suggested that the following language be used as condition of the Boat Club's proposed permit, Launching and retrieval in the north canal shall be restricted to vessels requiring boat repair. The applicant shall maintain a daily log of vessels launched and retrieved from the north canal travel lift. The applicant shall also maintain a log of incoming and outgoing boat repairs, which shall correlate with the travel lift log. DEP Ex. 43. A letter authored by Ms. Duncan dated November 18, 2003, was sent to Mr. Calvin Alvarez in the Southwest District Office of DEP. Signed by Brian Barnett, Interim Director of the FWC's Office of Environmental Services, it represents the Commission's comments and recommendations regarding the Boat Club's application under review in this proceeding. The letter contains a number of recommendations for conditions of the proposed permit, all of which were, in fact, made conditions of the permit as approved. In addition to standard construction conditions, development of a marina manatee education program, and installation of grates over certain pipes to prevent manatee drowning, the recommendations included the following: Of the 485 slips proposed for this marina, the number of powerboats allowed at this facility shall be limited to 445. The remaining slips (40) must be either occupied by sailboats or left unoccupied. Future requests for additional powerboats will be considered if the secondary and cumulative impacts associated with this increase are not expected to adversely affect the West Indian manatee. Storage of boats on trailers or open land racks shall be prohibited. Use of the travel lift in the north canal for boats less than 40 feet in length is prohibited except in emergencies (approaching hurricane etc.). Limitation on the use of this lift shall not exceed a 28-day rolling average of ten vessels a week for those vessels, except in emergencies (approaching hurricane etc.). Launching and retrieval of boats in the north canal shall be restricted to vessels requiring boat repair. The applicant shall maintain a daily log of vessels launched and retrieved from the north canal travel lift. The applicant shall also maintain a log of incoming and outgoing boat repairs, which shall correlate with the travel lift log. DEP Ex. 33, page 3. So long as the recommendations in the letter are conditions of the proposed permit, Ms. Duncan offered the opinion that the proposed permit "imposes minimal adverse impacts to manatees, and if any impacts do occur, they have been offset by" the permit conditions. (Tr. 784). Ms. Duncan's opinion was based on review of the project, "the historical background of the facility, manatee data, the requirements of the ERP rule, and [her] general knowledge of Lee County and manatee use in Lee County." Id. The 1990 Aerial: Proof of Maximum Historical Use Of particular import to Ms. Duncan's review was the historical background of the facility. Ms. Duncan reviewed a document provided to her by Hans Wilson and Associates, the Boat Club's environmental consultant and marine engineer. The document, enlarged as DEP Ex. 37, "has two coverages. It is an aerial photograph in 1990 of the facility. Overlaid on that is a CAD drawing done by Hans Wilson to outline what they determined to be existing boats that were uncovered in open storage on the facility in 1990." (Tr. 786-787). Ms. Duncan used the document to determine "actually how many boats were located coming out of this facility." (Tr. 787). She determined that there were 217 "Uncovered Dry Slips" (DEP Ex. 33) at the marina in 1990. Together with 61 authorized wet slips and 167 authorized "Covered Dry Slips" (id.), she reached a total of 445 slips at the marina as the historical maximum, 40 slips less than the 485 that were proposed in the Boat Club's current ERP application. Hence, FWC recommended that the number of power boat slips be restricted to 445 slips. Ms. Duncan chose the 1990 aerial for the basis of her recommendation because unlike the other aerials she looked at from 1993, 1999, 2000 and 2001, "[t]he 1990 aerial was the period of time that the facility appeared to be at full operating capacity in the sense that this was the aerial that showed the most boats and open storage on the uplands." (Tr. 787). Furthermore, she chose the 1990 aerial because "it represents the existing use of the facility before they started clearing it to prepare for building boat barns later in the 1990's." (Id.) Use of the 1990 aerial as the proof of maximum usage of the marina enabled Ms. Duncan to conclude, like Mr. Logan, that restricting the number of power boats slips at the marina to 445 would not introduce any new boats into the system. Usage at Other Times However fair to the Boat Club the choice of the 1990 aerial as to historical background of usage at the marina might be, it is not free of problems. First, the 1990 aerial is more than a decade old. In the interim, the marina was not shown by a number of aerials to have achieved the usage that appears to have peaked in 1990. The actual usage at the marina, in fact, has varied over time greatly and has been less (at times, much less), than what it was in 1990. Recent usage at the marina, in fact, has been far less than it was in 1990. At the 1999 administrative hearing before Administrative Law Judge Meale, Mr. Ruff, in answer to a question from the Administrative Law Judge, offered that the covered dry space and uncovered dry space totaled only about 200 slips rather than the 356 dry slips proposed in the Boat Club's current application: The ALJ: Okay. Can we deal with first what's in the ground or on the water, regardless of what's been authorized? If you need to confer with other witnesses, that would be fine. Mr. Uhle: Mr. Ruff is the person who knows how many dry spaces there are. The figure 61 wet slips I believe is correct. The ALJ: For present conditions? Mr. Uhle: For present conditions. Ms. Holmes: And that's permitted and in use. Mr. Uhle: Those are existing. The ALJ: Existing, right. * * * The ALJ: How about dry spaces. Mr. Ruff: Okay. The existing dry space, there is approximately in the two buildings and on the ground and outside racks, about 200. When we bought the property [in 1997], there were about 400 because we used the entire north peninsula for dead storage. We've eliminated that, effectively, so we've probably eliminated 150 boats from the property since we bought it. And they were there for a long time. Petitioner's Exhibit 9 (emphasis supplied). Mr. Ruff's testimony supported the administrative law judge's finding that "Deep Lagoon Marina presently consists of 61 wet slips, 200 dry slips, and other marina-related buildings." Sheridan, et al., v. Deep Lagoon Boat Club, Ltd., et al., DOAH Case No. 98-3901, Recommended Order (November 24, 1999), paragraph 6, and supported the finding that adding 227 dry slips so as to raise its dry slip capacity to 427 dry slips would "adversely impact the value of functions provided to manatees by the affected surface waters." Furthermore, the Sheridan II Recommended Order found: Manatee mortality has increased as boat traffic has increased. Substantial number of boaters have ignored speed limits. Quality manatee habitat in this critical area along the Caloosahatchee River is not plentiful. Id., paragraph 137. In light of these facts, the recommended order reached the conclusion, "[a]pplicant has failed to provide reasonable assurance that the secondary impacts of the proposed system will not adversely impact the abundance and diversity of wildlife and listed species, of which manatees are one, and the habitat of wildlife and listed species." Id., paragraph 138. In its final order in Sheridan II, DEP disapproved the maintenance and dredging exemption issue to the Boat Club, denied the Boat Club's request for a determination of entitlement to a maintenance and dredging exemption for dredging in the marina canals, and denied the Boat Club's application for an ERP to construct a SWMS on uplands at the Marina site. In the course of the final order, DEP "declined to reject the ALJ's mixed statements of law and fact concluding that increased boating activity and other Marina expansion activities authorized in the Original Permit constituted adverse secondary impacts of the proposed SWMS to water quality and to manatees and their habitat." Petitioners' Exhibit 8, DEP Final Order, OGC Case Nos. 98-1184 and 98-3047 and DOAH Case Nos. 98-3901 and 98-5409, p. 42 (January 28, 2000). Actual usage at the marina of 61 wet slips and 200 dry slips was confirmed again in Sheridan III both in the recommended order issued in January of 2000, and the final order by DEP. Ms. Duncan's testimony was forthright; her demeanor earnest. There is nothing to suggest that her opinion was anything other than honest and sincerely held. If one were to suspect that Ms. Duncan had a bias, it would be, in light of her position with the state and the recommendations she has made in the past, toward manatee protection. Her opinion, therefore, that the proposed permit does not adversely affect manatees should be given substantial weight. Ms. Duncan's opinion, however, is rejected. It is rejected because, just as Mr. Logan's, it is based on a faulty assumption: that approval of the permit will not introduce into the Caloosahatchee River system more boats that threaten the endangered manatee. The approval of the permit will allow more slips (485) and power boats (440) than have been actually at the marina since 1999 when Mr. Ruff testified before Administrative Law Judge Meale (261, 200 dry slips and 61 wet slips). The approval will allow more boat slips and power boats than the Boat Club claims in its proposed recommended order exist there now (400, 50 wet and 350 dry). Furthermore, it may be inferred that the upgrade, particularly if Clean Marina status is achieved and is publicized, will make it likely that the marina will be more attractive to boaters and will operate at full capacity. Full capacity is 184 more power boats above the capacity that served as the baseline in Sheridan II, and 224 more boat slips than the Sheridan II baseline. Furthermore, and most persuasively, the Department decided in Sheridan II that allowing a similar number of boats to operate in the Caloosahatchee River system constitutes adverse secondary impacts to the manatee and its habitat. There is nothing in this record that is shown to have occurred in the past three years that would justify overriding the Department's conclusion. Sovereignty Submerged Lands Lease The applicant has provided all information necessary to qualify for a proprietary authorization for a lease of sovereign submerged lands. But the Boat Club has failed to demonstrate that the lease will not be contrary to the public interest. See paragraph 204, below. Claim of Boat Club Violations Petitioners claim that the Boat Club has violated permit conditions or environmental law in the past in a number of different ways. There was no proof, however, of these violations. There was not even proof that the Department has ever issued a notice of violation to the Boat Club. Applicable Law In General At hearing, DEP produced a notebook with a cover page inside the book entitled "ALJ's Copy of Statutes and Rules." Official recognition was taken of the contents with no objection from any of the parties. Included in the notebook is an "Operation Agreement Concerning Regulation Under Part IV, Chapter 373, F.S., . . . Between South Florida Water Management District and Department of Environmental Regulation." Pursuant to the agreement, DEP reviews and takes final action on all applications for permits under Section IV of Chapter 373, Florida Statutes, for docking facilities and adjacent docking and boating-related development which includes "parking areas for the docking facility, dry storage facilities, boat sale and supply facilities, maintenance and repair facilities, associated seafood loading and processing facilities, restaurants, harbor master and marina administration facilities." Section II, A. 1(i), pp. 3 and 4 of the Operating Agreement. Section 373.413 provides that "the governing board [of the water management district] or the department may require such permits and impose such reasonable conditions as are necessary to assure that the construction . . . of any stormwater management system . . . will comply with the provisions of (Part IV of Chapter 373] and applicable rules . . . and will not be harmful to the water resources of the district." Section 373.414, entitled "Additional criteria for activities in surface waters and wetlands," provides: As part of an applicant's demonstration that an activity regulated under this part will not be harmful to the water resources or will not be inconsistent with the overall objectives of the district, the governing board or the department shall require the applicant to provide reasonable assurance that state water quality standards applicable to water as defined in s. 403.031(13) will not be violated and reasonable assurance that such activity in, on, or over surface waters or wetlands . . . . is not contrary to the public interest. * * * In determining whether an activity, which is in, on, or over surface waters . . . and . . . is not contrary to the public interest . . . the department shall consider and balance the following criteria: Whether the activity will adversely affect the public health, safety, or welfare or property of others; Whether the activity will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the activity will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; Whether the activity will be of a temporary or permanent nature; Whether the activity will adversely affect or will enhance significant historical and archaeological resources under the provisions of s. 267.061; and The current condition and relative value of functions being performed by areas affected by the proposed activity. See also Fla. Admin. Code R. 62-4.242; Fla. Admin. Code R. 40E- 4.302; and SFWMD Basis of Review, Section 4.2.3. Florida Administrative Code Rule 62-302.300 states the Department's anti-degradation permitting policy for surface water quality. Section (15) of the rule provides that pollution that causes or contributes to new violations of water quality standards or to continuation of existing violations is harmful to the waters of this State and shall not be allowed. Section (17) of the rule provides that the Department shall permit new discharge if it will not reduce the quality of the receiving waters below their classification and if the degradation is necessary under federal standards and circumstances clearly in the public interest and meets other requirements. Of particular pertinence to this case, the subsection goes on to state, "[p]rojects permitted under Part IV of Chapter 373, F.S., shall be considered in compliance with this subsection if those projects comply with the requirements of subsection 373.414(1), F.S." Those requirements, of course, include the statement with regard to "net improvement in water quality" in Section 373.414(1)(b)3. In Florida Administrative Code Rule 62-330.100, DEP has adopted by reference certain ERP rules of SFWMD for its use in conjunction with its existing rules when regulating surface water management systems, including activities on, in, or over wetlands or other surface waters under Part IV of Chapter 373. The Basis of Review for Environmental Resource Permit Applications within the South Florida Water Management District August 1995 ("BOR") is also contained in the notebook of "ALJ's Copy of Statutes and Rules" produced at hearing as applicable law. Among the BOR's Environmental Criteria to be "implemented in a manner which achieves . . . a project permitting goal, of no net loss in . . . surface water functions" (Section 4.0, BOR) is Section 4.2.1. It requires the exploration of design modification to reduce or eliminate adverse impacts to surface water functions. The evidence establishes that the proposed surface water management system will enhance surface water functions by providing a net improvement of the water quality of marina's receiving waters. Section 4.2.2 of the BOR requires that the applicant "provide reasonable assurances that the regulated activity will not impact the values of wetland and other surface water functions so as to cause adverse impacts to: (a) the abundance and diversity of fish, wildlife and listed species; and (b) the habitat of fish, wildlife and listed species." The Boat Club has failed to provide assurances that the upgrade to the marina will not cause adverse impacts to manatees and their habitat. The opinions of the experts presented by the Boat Club that there will be no adverse impacts are based on the faulty assumption that the upgrade will not add more boats into the Caloosahatchee River system. The boating restrictions imposed by the federal, state and local governments, moreover, have not been shown in this proceeding to mitigate adverse impacts to the manatee and its habitat that will be produced by the introduction of additional boats, power and otherwise, into the River system. The Public Interest Test Deep Lagoon has been found in previous recommended orders and DEP final orders not to be among Florida's Outstanding Waters, even though it is an arm of the Caloosahatchee River and the River is so listed. The parties do not contend otherwise. They have structured their arguments along the line that the proposed permit must be shown to be "not contrary to the public interest." Section 373.414(1). Of the seven criteria of Section 373.414(1), which must be considered and balanced in determining whether the project is contrary to the public interest, it has been shown that there is no adverse impact with regard to criteria 1., 3., 4., and 6. In fact, for example, as the Boat Club points out with regard to criterion 1., "[e]xcept for mosquito control, the testimony and evidence demonstrated that this proposed project will have a positive impact on each and every one of [the] concerns" (Respondent, Deep Lagoon Boat Club Ltd.'s Proposed Recommended Order, p. 53) listed in Section 4.2.3.1 of the BOR for assessment of hazard to public health, safety with respect environmental issues. This leaves criteria 2., 5., and 7. Implementation of the proposed surface water management system will have a positive affect on the conservation of fish and wildlife but the upgrade otherwise will not. The project is of a permanent nature, a matter the Boat Club concedes. (Respondent Deep Lagoon Boat Club Ltd.'s Proposed Recommended Order, p. 55). The surface water management system will improve water quality in the area. The remainder of the upgrade will diminish the value to manatees and of the manatee habitat of the areas affected. Reasonable Assurances Section 4.2.4 of the BOR requires that an applicant provide "reasonable assurance that the regulated activity will not violate water quality standards in areas where water quality standards apply." Water quality standards will not be violated as a result of the proposed project. Reasonable assurances have been provided both in the short term with best management practices during construction, and in the long term with the Marina Management Plan governing the operation of the marina for the life of the facility. The Boat Club offered reasonable assurance that future water quality will be in compliance by detailed maintenance and reporting procedures for the surface water management system and the closed loop systems, and monitoring of water quality and sediments. Sections 4.2.4.2 and 4.2.4.3 of the BOR require long term water quality considerations. Reasonable assurances were offered that the project will not cause water quality violations. Flushing has been improved by making the canals more shallow, and will be further improved by the culverts that will connect the north and main canals. The fueling facilities are conditioned upon a detailed operations and procedures commitment in the area of spill response, minimizing the effects of any spills, as required by Section 4.2.4.3(f). The marina will have publicly available pump-out facilities for boat heads at a nominal cost to minimize improper disposal, as required by Section 4.2.4.3(g), and will not have live-aboards. The disposal of solid waste, such as garbage and fish cleaning debris, has been addressed to prevent disposal into wetlands or other surface waters, as required by Section 4.2.4.3(h). The pollutant leaching characteristics of pilings has been addressed as required by Section 4.2.4.3(i), by the replacement of the existing, treated wood docks with PVC and concrete structures. Anti-fouling paints on hulls have been addressed by requiring all wash-downs to take place in the closed loop contained areas that overflow in storms to the sewer system. Additionally, any boat scrapings are contained and disposed of by a contaminant disposal contractor, and the marina uses only low-copper bottom paints. The permit conditions, as well as the plans, address the short-term water quality impacts of the proposed system, as required by Section 4.2.4.1 of the BOR. The project plans attached to the permit include provisions for erosion and siltation barriers, and similar devices during construction. The permit conditions also require temporary erosion control barriers to remain in place and be inspected daily during all phases of construction until soils stabilize and vegetation has been established. All practices are required to be in accordance with the guidance and specifications described in Chapter Six of the Florida Land Development Manual: A Guide to Sound Land and Water Management (Department of Environmental Regulation 1988), unless a project-specific erosion and sediment control plan is approved as part of the permit. Additionally, all access for construction activities, including placement of floating docks into the water, must occur via the existing boat ramps, travel lift and fork lift areas of the marina. At no time are mangroves affected unless specifically authorized by the permit to be altered or trimmed to accommodate construction or access operations. From a hydrographic standpoint, the project is approvable. Section 4.2.4.5 of the BOR, entitled "Where Ambient Water Quality does not Meet State Water Quality Standards," provides in part: If the site of the proposed activity currently does not meet state water quality standards, the applicant must demonstrate compliance with the water quality standards by meeting the provisions in 4.2.4.1, 4.2.4.2, and 4.2.4.3, as applicable, and for the parameters which do not meet water quality standards, the applicant must demonstrate that the proposed activity will not contribute to the existing violation. The proposed project will result in a net improvement of the water quality standards, and will not contribute to any exceedances where exceedances exist. Section 4.2.7 of the BOR requires that an applicant provide reasonable assurances that a regulated activity will not cause adverse secondary impacts to the water resource as described in paragraphs (a) through (d) of the section. The section stresses the import of protection of endangered species such as the manatee: Aquatic or wetland dependent fish and wildlife are an integral part of the water resources which the District is authorized to protect under Part IV, Chapter 373, F.S. Those aquatic or wetland dependent species which are listed as threatened, endangered or of special concern are particularly in need of protection. As discussed elsewhere, the applicant has failed to provide reasonable assurances that the proposed project will not cause adverse impacts to the manatee. Florida Administrative Code Rule 18-21.004(1)(a) provides that "all activities on sovereignty lands must not be contrary to the public interest except for sales which must be in the public interest." "Public interest means demonstrable environmental, social, and economic benefits which would accrue to the public at large as a result of a proposed action, and which would clearly exceed all demonstrable environmental, social, and economic costs of the proposed action. In determining the public interest in a request for . . . lease . . . in sovereignty lands . . ., the board shall consider the ultimate project and purpose to be served by said . . . lease . . . ." Fla. Admin. Code R. 18-2.003(40). While conditioned upon the construction of the surface water management system that will provide a net improvement in water quality to a water body that does not meet water quality standards, implementation of the Marina Management Plan, and execution of a DEP-approved lease agreement, the proposed activity has not been shown to be not contrary to the public interest because of adverse secondary impacts to manatees.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a final order be entered by the Department of Environmental Regulation that the application by the Deep Lagoon Club Ltd. for a Consolidated Environmental Resource Permit and Sovereign Submerged Lands Authorization be denied.

The Issue The preliminary issue in this case is whether the South Florida Water Management District (District) has jurisdiction over the Petition for Formal Administrative Hearing (Petition) filed by the Save the Manatee Club (Club)--i.e., whether the Petition was timely or, if not, if the District has jurisdiction under principles of equitable tolling or excusable neglect.
Findings Of Fact On October 11, 1999, Hidden Harbor filed with the District an application for an Environmental Resource Permit (ERP) to construct and operate a surface water management system serving a proposed residential development in Lee County, Florida. In January 2001, the Club sent an email to the Florida Wildlife Conservation Commission (FWCC) stating that it was concerned about Hidden Harbor's Application No. 991011- 13, as it might impact an area the Club would like to see as a manatee sanctuary, and was requesting copies of all FWCC documents relating to the permit. FWCC forwarded a copy of this email to the District on January 19, 2001. At the time, the Club's internet website gave the address of its main office in Maitland, Florida, as the Club's official mailing address. On April 9, 2001, the Club opened a Southwest Florida regional satellite office in Estero, Florida, and installed Laura Combs as Regional Coordinator in charge of that office. Responsibility for monitoring the Hidden Harbor application was delegated to Combs and the satellite office. Nonetheless, the Club's website continued to give the address of its main office in Maitland, Florida, as the Club's official mailing address. Combs's prior work experience with the Club was as assistant director of governmental relations in Tallahassee, Florida. In that position, she tracked legislation and actions of the Governor and Cabinet that were of interest to the Club. She had no role in the filing of petitions for administrative hearings on actions of governmental agencies. Combs's education included a bachelor's degree in English and a master's degree in urban and regional planning. She did not have specific legal education in the filing of petitions for administrative hearings on actions of state governmental agencies. On May 30, 2001, the District mailed to the Club at its Maitland office address a letter enclosing the "District's staff report covering the [Hidden Harbor] permit application [No. 991011-13]" and notifying the Club that the "recommendations as stated in the staff report [to grant the attached draft permit] will be presented to our Governing Board for consideration on June 14, 2001." The Club also was advised: Should you wish to object to the staff recommendation or file a petition, please provide written objections, petitions and/or waivers (refer to the attached "Notice of Rights") to [the District's deputy clerk]. The "Notice of Rights" addresses the procedures to be followed if you desire a public hearing or other review of the proposed agency action. You are advised, however, to be prepared to defend your position regarding the permit application when it is considered by the Governing Board for final agency action, even if you agree with the staff recommendation, as the Governing Board may take final agency action which differs materially from the proposed agency action. The Notice of Rights stated that it was intended to conform to the requirement of Section 120.569(1), Florida Statutes, to "inform the recipient of any administrative hearing or judicial review that is available under this section [120.569(1)], s. 120.57 or s. 120.68." It cautioned: Please note that this Notice of Rights is not intended to provide legal advice. Not all the legal proceedings detailed below may be an applicable or appropriate remedy. You may wish to consult an attorney regarding your legal rights. The Notice of Rights included a section entitled "Petition for Administrative Proceedings," which stated in pertinent part: A person whose substantial interests are affected by the South Florida Water Management District's (SFWMD) action has the right to request an administrative hearing on that action. The affected person may request either a formal or an informal hearing, as set forth below. A point of entry into administrative proceedings is governed by Rules 28-106.111 and 40E-1.511, Fla. Admin. Code, (also published as an exception to the Uniform Rules of Procedure as Rule 40E-0.109), as set forth below . . .. Formal Administrative Hearing: If a genuine issue(s) of material fact is in dispute, the affected person seeking a formal hearing on a SFWMD decision which does or may determine their substantial interests shall file a petition for hearing pursuant to Sections 120.569 and 120.57(1), Fla. Stat. or for mediation pursuant to Section 120.573, Fla. Stat. within 21 days . . . of either written notice through mail or posting or publication of notice that the SFWMD has or intends to take final agency action. Pertinent to this case, the Notice of Rights included a verbatim reproduction of Florida Administrative Code Rule 28- 106.201, addressing required contents of a petition to initiate proceedings involving disputed issues of material fact. Rules 28-106.111, 40E-1.5111, and 40E-0.109 were not reproduced in the Notice of Rights. It is not clear from the evidence when the letter dated May 30, 2001, with attachments (the Notice Correspondence), was received in the Club's Maitland office. It was not date-stamped, as time-sensitive correspondence normally would be. Apparently, it was decided to forward the Notice Correspondence to the new satellite office in Estero for handling. Combs received the forwarded Notice Correspondence in early June 2001. This was the "first time [Combs] had been through this type of process." Combs reviewed the Notice Correspondence, eventually focusing on paragraph 1.a. of the "Petition for Administrative Proceedings" section of the Notice of Rights. She did not read any of the cited statutes and rules except for the rules reproduced verbatim as part of the Notice of Rights. Combs made conflicting statements regarding her understanding of the District's administrative process. However, it appears that she understood that the Club could file a petition within 21 days of receipt of the Notice Correspondence, or within 21 days of the "final" action of the District's Governing Board. She testified that, because the Notice Correspondence did not bear a date-stamp, it was unclear when the first 21-day time period began or ended; as a result, she decided to wait until the District's Governing Board took "final" action and file a petition within the second 21-day time period. Combs appeared at the meeting of the District's Governing Board on June 14, 2001, and spoke in opposition to issuance of the draft permit. Notwithstanding the Club's opposition, the Governing Board decided to issue the draft permit. Combs does not have authority to file petitions for administrative hearings on District actions. She consulted with her supervisor, Patricia Thompson, and they made a recommendation to the Club's governing board, which has ultimate authority to file petitions. Prior to Combs's involvement in the Hidden Harbor application, the Club had staff legal counsel, who could be consulted with respect to the filing of petitions and would advise the Club's governing board. However, the Club did not have staff legal counsel at the time of Combs's involvement and through the time of filing of this petition. (The Club now again has staff legal counsel.) Neither Combs nor Thompson saw any need to consult an attorney. It is not clear when the recommendation of Combs and Thompson was presented to the Club's governing board or when the Club's governing board made its decision to file the Petition. Neither Thompson nor any member of the Club's governing board (nor anyone else who may have participated in the decision to file the Petition) testified. Several (according to Combs, approximately 12) times after the District's Governing Board's meeting on June 14, 2001, Combs telephoned the District's offices to obtain a copy of the District's Governing Board's "final" action when it was reduced to writing. It is not clear from the evidence why several telephone calls were required. Eventually, on June 26, 2001, Combs received a copy of the permit issued to Hidden Harbor; there was no Notice of Rights attached. On July 17, 2001, the Club filed its Petition challenging the permit issued to Hidden Harbor. In the meantime, Hidden Harbor had obtained a final development order from Lee County in reliance on the Club's failure to petition for an administrative hearing. The Club is not a newcomer to Florida's administrative process. It can be officially recognized that the Club has participated in numerous proceedings before DOAH. At least one of those cases involved issues similar to those presented for determination in this case. See Conclusion of Law 32, infra.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the South Florida Water Management District enter a final order dismissing the Petition. DONE AND ENTERED this 6th day of December, 2001, in Tallahassee, Leon County, Florida. _________________________________ J.
