The Issue The issue is whether Respondent HBJ Investments, Inc. is entitled to an environmental resource permit to facilitate the construction of the Betty Jones Spa on property adjacent to property owned by Petitioner.
Findings Of Fact On November 17, 1998, Respondent HBJ Investments, Inc. (Applicant) filed an application (Application) with the South Florida Water Management District (District) for an environmental resource permit (ERP). The Application is for a Standard General (minor systems) ERP. The Application states that the proposed surface water management system is to serve a 11,564 square foot health spa with associated infrastructure improvements, such as parking, utilities, landscaping, and a stormwater detention facility. Section H of the Application responds to form questions that are intended to determine whether an application meets the requirements of a standard general ERP for a minor surface water system. Among the threshold requirements is that the proposed discharges from the site "will meet State water quality standards, and the surface water management system will meet the applicable technical criteria for stormwater management in the Basis of Review." Another threshold requirement is that the proposed activities will not cause significant adverse impacts individually or cumulatively. The Application states that the water quality treatment system will be on-line detention with effluent filtration. The Application and related documents describe the system in greater detail. The system consists of drains, inlets, a swale, an underground vault to provide effluent filtration through a sand filter and perforated pipe, an internal oil and grease skimmer, a control box, and a 15-inch diameter reinforced concrete pipe providing outfall from the vault. By Notice of Final Agency Action for Approval dated February 4, 1999, the District proposed the issuance of a "Standard General for Minor Surface Water Management Systems" ERP for the construction, operation, and maintenance of the proposed system (Permit). Permit Specific Condition 2 requires: "The discharges from this system shall meet state water quality standards as set forth in Chapter 62-302 and Rule 62-4.242, F.A.C., for class waters equivalent to the receiving waters." Permit Specific Condition 8 requires, for vault systems, that the system become dry within 72 hours after a rainfall event. Permit Specific Condition 9 requires the operation and maintenance entity to submit inspection reports for inspections to be performed every 18 months. Permit Specific Condition 10 requires a water quality monitoring program for systems, such as the proposed system, using an internal oil and grease skimmer. This condition obligates HBJ to take three samples during each of the first two annual rainy seasons following the commencement of operation of the system. The monitoring must take place immediately after rainfall events of sufficient magnitude to cause a discharge from the outfall structure. If the discharged water does not meet water quality standards for oil and grease, as established by Rule 62.302.510(3)(k), Florida Administrative Code, then the permittee must alter the system to attain compliance for this water quality parameter. The subject parcel is bounded by Fourth Avenue South on the north, First Street South on the east, Second Street South on the west, and an unnamed alley on the south. This site is just south of Al Lang Field. In its present state, the parcel is nearly entirely pervious surface. Some of the stormwater flowing onto the parcel percolates into the soils, and the remainder flows into City of Saint Petersburg stormwater sewers, from which it is carried about two city blocks to Tampa Bay, where it is discharged. The parcel was formerly used for single-family residential housing, but is now mostly cleared. The runoff from the site presently carries mostly sediments. After the proposed construction, 79 percent of the parcel would consist of impervious surface. Although small areas of the developed parcel might remain vegetated, and thus add nutrients into the runoff, the primary change in the runoff will consist of the addition of automobile-related contaminants, including, but not limited to, oil and grease. HBJ's engineer designed the proposed surface water management system to treat the first one-half inch of stormwater runoff. The engineer's report notes, in a letter dated November 13, 1998, that siltation in the vault reduces storage volume, so it is "required that cleaning be done every six (6) months." The report suggests the removal of grass clippings from the parking area, so that they are not transported to the retention vault. The report suggests that the underdrain system should be backflushed periodically, and the control structure should be checked monthly and all debris cleared. In general, the system would collect runoff from the roof downspouts and parking area. The system would provide treatment of the first 1/2 inch of runoff by capturing it in the vault, where it would filter through a layer of several cubic feet of sand before entering a perforated pipe leading to the City stormwater sewer. Runoff from rainfall in excess of the first 1/2 inch would receive little, if any, treatment. It is implicit that the first 1/2 inch of rainfall contains the first flush of contaminants from impervious surfaces. Nothing in the record specifies the efficacy of treatment provided by this standard, although it obviously is less than 100 percent efficient because of the higher standard imposed upon systems discharging into Outstanding Florida Waters (OFW). However, a pre- and post-development analysis of the runoff from the subject parcel would reveal an unknown additional volume of runoff from the developed site, due to the replacement of pervious surface with impervious surface. It is unclear whether the developed site would generate a reduced volume of sediments in this increased volume of runoff. Although little vegetated surface would exist post-development, the record does not reveal the extent to which the pre-development pervious area fails to capture the sediments prior to their entering the City stormwater system. More problematic are the automobile-related contaminants, such as oil and grease, that will be introduced into the runoff by the developed site. Presumably, the runoff from the undeveloped site contains few, if any, such contaminants. Thus, any automobile-related contaminants discharged from the surface water management system would likely be an increase from the amount of such contaminants presently discharged from the site. The runoff from the developed site would enter the City of Saint Petersburg stormwater sewer system and would be released in the nearby Tampa Bay. The record does not disclose the stormwater sewer line transporting the discharge, nor the outfall of the line into Tampa Bay. By stipulation, the parties agreed that Tampa Bay is an OFW and that discharge from the developed site would enter the City of Saint Petersburg stormwater sewer system. Tampa Bay is classified as Class II waters, which are approved for shellfish harvesting. The record does not disclose the point of discharge of the City stormwater line that would receive discharge from the developed site. However, the proximity of the site to Tampa Bay strongly suggests that the outfall would be in Tampa Bay, and it is only slightly less probable that the outfall would be at a point in the bay in the immediate vicinity of the site. The record suggests that the waters of Tampa Bay likely to receive the discharge from the site are impaired. For example, water quality conditions mandated the closing of "Lower Tampa Bay" to shellfish harvesting, for an unstated period of time, effective at sunset on July 5, 1999. Also, the Department of Environmental Protection listed two bayous in the immediate vicinity of the site as noncompliant with federal water quality standards due to excessive coliform bacteria counts and nutrients and insufficient levels of dissolved oxygen. The Basis of Review (BOR) is a document adopted by the District. It contains specific "criteria" for permitting. However, as BOR Section 1.3 explains, the goal of these criteria is to meet District water resource objectives, and the criteria are "flexible." Alternative methods of meeting "overall objectives" may be acceptable, depending upon the "magnitude of specific or cumulative impacts." The criteria, which are flexible, are the means by which the District assures that it meets its objectives, which are not flexible. BOR Section 3.1.0 recognizes that "a wide array of biological, physical and chemical factors affect the functioning of any wetland or other surface water community. Maintenance of water quality standards in applicable wetlands and other surface waters is critical to their ability to provide many of these functions." BOR Section 3.1.0 elaborates: "It is the intent of the Governing Board [of the District] that the criteria in subsections 3.2 through 3.2.8 be implemented in a manner which achieves a programmatic goal and a project permitting goal of no net loss of wetlands or other surface water functions." BOR Section 3.1.1 requires that an applicant provide "reasonable assurance" of several things. BOR Section 3.1.1(a) requires that "a regulated activity will not adversely impact the value of functions provided to fish, wildlife and listed species, including aquatic and wetland dependent species, by wetlands and other surface waters and other water related resources of the District. (paragraph 40D-4.301(1)(d), F.A.C.) (see subsection 3.2.2)." BOR Section 3.1.1(c) provides that: a regulated activity will not adversely affect the quality of receiving waters such that the water quality standards set forth in Chapters 62-3, 62-4, 62-302, 62-520, 62-522 and 62-550, F.A.C., including any antidegradation provisions of Sections 62-4.242(1)(a) and (b), 62-4.242(2) and (3), and 62-302.300 and any special standards for Outstanding Florida Waters . . . set forth in sections 62-4.242(2) and (3), F.A.C., will be violated (paragraph 40D-4.301(1)(e), F.A.C.). BOR Section 3.1.1(d) provides that "a regulated activity . . . located in close proximity to Class II waters . . . will comply with the additional criteria in subsection 3.2.5 (paragraph 40D-4.302(1)(c), F.A.C.)." BOR Section 3.1.l(f) provides that "a regulated activity will not cause adverse secondary impacts to the water resources (paragraph 40D-4.301(1)(f), F.A.C.) (see subsection 3.2.7)." BOR Section 3.1.1(g) provides that "a regulated activity will not cause adverse cumulative impacts upon wetlands and other surface waters . . . (paragraph 40D-4.302(1)(b), F.A.C.) (see subsection 3.2.8)." BOR Section 3.2.4 provides that an applicant must provide "reasonable assurance that the regulated activity will not violate water quality standards in areas where water quality standards apply. . . . The following requirements are in addition to the water quality requirements found in Chapter 5." BOR Section 3.2.4.2(c) provides that the applicant must address the long-term water quality impacts of a proposed system, including "prevention of any discharge or release of pollutants from the system that will cause water quality standards to be violated." BOR Section 3.2.5 provides: The special value and importance of shellfish harvesting waters to Florida's economy as existing or potential sites of commercial and recreational shellfish harvesting and as a nursery area for fish and shell fish is recognized by the District. In accordance with section 3.1.1.(d), the District shall: (b) deny a permit for a regulated activity in any class of waters where the location of the system is adjacent or in close proximity to Class II waters, unless the applicant submits a plan or proposes a procedure which demonstrates that the regulated activity will not have a negative effect on the Class II waters and will not result in violations of water quality standards in the Class II waters. BOR Section 3.2.7 provides that an applicant must provide "reasonable assurance" that "a regulated activity will not cause adverse secondary impacts to the water resource" as described in this section. However, this section explicitly disregards negligible or remotely related secondary impacts. BOR Section 3.2.8 provides that an applicant must provide "reasonable assurance" that "a regulated activity will not cause unacceptable cumulative impacts upon wetlands and other surface waters " BOR Section 4.2 limits off-site discharge "to amounts which will not cause adverse off-site impacts." For a proposed activity within an open drainage basin, as is the subject proposed activity, the allowable discharge is (presumably the greatest of) any amount determined in previous District permits, the legally allowable discharge at the time of the permit application, or historic discharge. Historic discharge is the peak rate at which runoff leaves a parcel of land by gravity under existing site conditions. BOR Section 5.1 requires that proposed discharges meet applicable state water quality standards. This chapter of the BOR requires that proposed systems satisfy certain quantitative criteria, depending on the type of water treatment system. However, BOR Section 5.1 warns: in certain instances a design meeting those standards may not result in compliance with the state water quality standards referenced above. Unless an applicant has provided reasonable assurance that a design will not cause or contribute to a violation of state water quality standards, the District may apply more stringent design and performance standards than are otherwise required by this chapter. Projects designed to the criteria found in this section shall be presumed to provide reasonable assurance of compliance with the state water quality standards referenced above. . . . BOR Section 5.2 sets quantitative criteria for various types of surface water management systems. The subject system is a detention, on-line treatment system. BOR Section 1.7.5 defines "detention" as the "delay of storm runoff prior to discharge into receiving waters." BOR Section 1.7.28 defines "on-line treatment system" as a "dual purpose system that collects project runoff for both water quality and water quantity requirements. Water quality volumes are recovered through percolation and evaporation while water quantity volumes are recovered through a combination of percolation, evaporation, and surface discharge." BOR Section 5.2.b applies to "[d]etention with effluent filtration system (manmade underdrains)." BOR Section 5.2.b.1 provides that proposed activities draining less than 100 acres "shall treat the runoff from . . . the first one-half inch runoff." BOR Section 5.2.b.6 adds: "Maintenance of filter includes proper disposal of spent filter material." BOR Section 5.2.c applies to "on-line treatment system[s]." This section also requires the treatment of the first one-half inch of runoff. However, BOR Section 5.2.e provides: Projects discharging directly into Outstanding Florida Waters (OFW) shall be required to provide treatment for a volume 50 percent more than required for the selected treatment system . . .. Applicant has provided reasonable assurance that the proposed surface water management system would not cause adverse water quantity impacts to receiving waters and adjacent lands and would not cause flooding. In terms of water quantity, the proposed system is designed to meet the requirements of the ten-year storm. The subject site is a short distance from Tampa Bay, and, as already noted, it is very likely that the runoff discharges into Tampa Bay at a location not far from the subject site. Thus, water quantity and flooding are irrelevant to this case. However, Applicant has not provided reasonable assurance that the proposed surface water management system would not cause adverse impacts to the value of functions provided to fish and wildlife by nonwetland surface waters and would not adversely affect the quality of receiving waters. The receiving waters of the discharge from the subject site are Class II waters that are OFW. However, these waters are also impaired sufficiently as to be in violation of certain federal water quality standards and to require the closure, at least at times, of shellfish harvesting. There are three deficiencies in the proposed permit. First, it does not specify, in clear and enforceable language, an inspection and maintenance program, which includes the undertaking by the Applicant to backwash the system at specified intervals, to replace the sand filtration medium at specified intervals, to dispose of the sand filtration medium so that the captured contaminants do not reenter waters of the state, to monitor the water discharged from the oil and grease skimmer at specified intervals following the first two years' monitoring, and generally to take any necessary action to correct deficiencies uncovered from inspections. Second, the treatment of the first 1/2 inch of runoff is insufficient for the system, which is discharging directly into an OFW. BOR Section 5.2.e raises this standard to 3/4 inch. Direct discharges requires the identification of the first receiving waters. Receiving waters are waters of the state that are classifiable as Class I-V waters. Receiving waters thus do not include waters in a stormwater sewer pipe, which are not waters of the state nor are they classifiable. Water quality determinations often require comparison of the quality of the discharged water with quality of the receiving waters. The off-site piping of the discharged water does not preclude such comparison. In such case, the analysis extends to the first receiving waters into which the pipe empties. The District's argument to the contrary invites circumvention of those provisions enacted and promulgated for the protection of OFWs. For example, several owners of land abutting an OFW could establish a jointly owned stormwater sewer line so that the point of comparison for their discharge would be the waters in the pipe rather than the OFW. Third, Applicant failed to submit a plan or propose a procedure demonstrating that the proposed activity would not have a negative effect on the Class II waters of Tampa Bay and would not result in violations of water quality standards in these Class II waters. The District failed to determine the outfall of the discharge from the subject site, so it failed to enforce the requirement of the plan required by BOR 3.2.5 for the protection of the special value of Class II waters. Although required to account for cumulative impacts, the plan will necessarily reflect the characteristics of the site--e.g., 1.6 acres contributing largely automobile-based contaminants and not nutrients--and the characteristics of the receiving waters--e.g., Tampa Bay is vast and relatively impaired, though, in the vicinity of the subject site, more likely due to excessive nutrients.

Findings Of Fact The Applicant/Respondents, Melvin and Mary Thayer have applied to the Department of Environmental Regulation (Department) for a "dredge and fill permit" seeking authorization to remove an existing 32-foot wooden fence and install in its place a chain-link fence, which as originally applied for would not extend more than 32 feet waterward from the 64-foot mean sea level elevation of Alligator Lake as marked by the waterward end of the existing wooden fence. The fence proposed would be five feet high and would possess a gate at its landward end which would permit pedestrian passage in both directions around the near-shore area of the lake. The project site is located approximately 400 feet south of U.S. 441-192 and adjacent to Alligator Lake, lying one mile west from Bay Lake within Section 10, Township 26 South, Range 31 East in Osceola County, Florida. As clarified and amended prior to hearing, the application now requests the permit to authorize, instead, a 26-foot fence extending that distance waterward from the 64-foot mean sea level elevation. The Department has permitting jurisdiction under Chapters 253 and 403, Florida Statutes as well as Chapter 17-4, Florida Administrative Code. There is no dispute that the Department has jurisdiction of the permitting of the subject fence inasmuch as the fence would be constructed waterward of the 64-foot mean sea level elevation or the "high pool" level of Alligator Lake in Class III waters of the state. Additionally, the area of the project waterward of the 64- foot mean sea level elevation lies on sovereign lands of the State of Florida under the jurisdiction of the Department of Natural Resources. That Department, as yet, has not issued a permit for use of sovereign land for the intended purpose as envisioned by Section 253.77, Florida Statutes. Ed Edmunson was tendered by both Respondents as an expert witness and was accepted as to his expertise in biological assessment of dredge and fill construction projects. It was thus established that the construction and installation of the fence and removal of the existing fence would cause no Class III water quality violations. Additionally, it was established that no navigational impediment would result from the fence as presently proposed which only involves a 26-foot fence extending from the 64-foot mean sea level elevation waterward in a perpendicular direction from the shore and near-shore of Alligator Lake. Parenthetically it should be noted that the original proposal involved extending the fence 32-feet waterward and then installing a right angle section parallel to the shoreline for an indeterminate distance. The right angle portion of the fence has been deleted from the permit application and the portion perpendicular to the shoreline has been amended from 32 feet down to 26 feet from the 64-foot mean sea level elevation. In that connection, it was established by witness Walter, accepted as an expert in the field of engineering, that on January 7, 1985, the water line of Alligator Lake was at 62.4 feet mean sea level elevation and the end of the existing 32-foot wooden fence was 16 feet from the then existing waterline of the lake. If the water in the lake was at the 64 feet mean sea level elevation or "high pool" stage, which has occurred on the average of once every three years, the water at the end of the fence would still be only .9 feet in depth at the waterward extreme end of the proposed 26-foot fence. Indeed, it was established with- out contradiction by the Applicant, Melvin Thayer, that in the 17 or 18 years he has observed the project site, that only "seven or eight inches of water is the most depth he has seen at the end of the fence." Thus, the fence as proposed to be installed, will pose no impediment or hazard to the navigation of fishing boats, skiing boats or other craft, and, in that regard, a dock in close proximity to the site of the proposed fence extends approximately 90 feet waterward at the present time. In view of the Petitioner's other objection to the fence concerning their feared loss of access to walk around the near-shore area of the lake to visit friends and the like, the permit applicants have agreed to install a gate for public access anywhere specified by the Department along the extent of the proposed fence. The testimony of Petitioner's witnesses, including a representative of the Game and Fresh Water Fish Commission, consists largely of objections to the precedent of permitting a private fence to be constructed in the waters of the state and on state water bodies, but no impediment to navigation has been established especially since the neighboring dock and numerous other docks around the shoreline of the lake extend waterward much farther than will the proposed fence. No degradation to water quality has been established to result from the proposed project. The fence has not been shown to be contrary to the public interest since it will not interfere with wildlife habitat or natural resources, nor impede navigation in any way, and was shown not to impede any public use of the lake or the near-shore area of the lake, in view of the access gate to be provided in the fence. In short, reasonable assurances have been provided that all permitting criteria within the Department's jurisdiction at issue in this proceeding will be complied with, although a permit from the Department of Natural Resources authorizing use of the state lands involved has not been issued as yet.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That the application of Melvin and Mary Thayer for authority to remove an existing fence and to install a fence extending 26 feet waterward of the 64-foot mean sea level elevation of Alligator Lake with an attendant public access gate installed therein be GRANTED upon satisfaction of the above-stated condition.

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

Findings Of Fact The Parties and the Property. The Respondent, HORNE, owns or has options to purchase approximately 24.35 acres of real property at the southwest corner of U.S. Highway 41 and State Road 50 Bypass in Brooksville, Florida. The Petitioner, the ASSOCIATES, owns approximately 67.5 acres of real property to the south and downstream from the HORNE property. The ASSOCIATES' property is presently undeveloped. The HORNE property contains an existing Publix shopping plaza, a mobile home sales office and vacant lands. The Publix plaza was previously permitted by the DISTRICT before it was constructed. The Surface Water Permit Application On August 7, 1992, HORNE submitted its application for surface water permit No. 400317.02. The application sought approval to construct a surface water management system for a proposed new K-Mart store on HORNE's property. On November 3, 1992, the DISTRICT issued notice of final agency action approving issuance of permit No. 400317.02 to HORNE. The day before the original final hearing in this matter scheduled for March 1993, new information from a study called the Peck Sink Watershed Study came to light which rendered the project as then designed unpermittable. This information resulted in the surface water management system being redesigned. On April 1, 1993, the DISTRICT notified all of the parties that the redesigned surface water management met District rule criteria. This resulted in issuance of what became known as the April 1 submittal. On May 12, 1993, in response to concerns raised by the ASSOCIATES at depositions on May 10, 1993, HORNE produced the May 12 submittal and provided it to all parties on that same date. The changes in design reflected on the May 12 submittal related to lowering the pond bottoms one foot below the orifices and changing the contour lines on the outside of Pond 5A. On May 13, 1993, further minor changes were made to the permit materials. Specifically, the changes were: reflecting on the engineering worksheets the lowering of the pond bottoms accomplished on the May 12 submittal, correction of the contour line on the outside of Pond 5A and showing the amount of additional fill into the 100-year floodplain caused by the addition of the contour line to the outside of Pond 5A. In reviewing HORNE's application, the District applied the standards and criteria set forth in Chapter 40D-4, Florida Administrative Code, and the Basis of Review for Surface Water Management Permit Applications. Compliance with DISTRICT Permitting Criteria Water Quantity The main two areas considered by the DISTRICT in assessing water quantity in a closed basin are: attenuating the peak rate of discharge for the 25 runoff for the 100 The peak rate of runoff for this project for the 25 (2) cubic feet per second (cfs) less in the post-developed condition than in the pre-developed condition, as shown on the April 1 submittal. No changes were made between the April 1 and May 12 or 13 submittals relating to the peak rate of discharge. The difference in the volume of runoff between the pre-developed and post-developed condition during the 100-year storm is being retained on site, as shown on the April 1 submittal. Therefore, DISTRICT rule criteria for the peak rate and volume of runoff were met on the April 1 submittal. Lowering the bottoms of the detention ponds on the May 12 and 13 submittals resulted in additional post 100 system, as redesigned to retain this additional 100-year volume, exceeds the DISTRICT's 100 Floodplain Encroachment Under the DISTRICT's floodplain encroachment standards, any fill within the 100 out an equivalent volume of fill elsewhere on the property. HORNE's application satisfies the DISTRICT's floodplain standards. HORNE is filling 1.59 acre feet of the floodplain and creating 1.75 acre feet of compensation. The floodplain compensation will be above the seasonal high water table, as required by Section 3.2.1.4 of the DISTRICT's Basis of Review. The original, existing seasonal high water table will be lowered as a result of the excavation so that the entire floodplain compensation area will be above the seasonal high water table. Water Quality A wet detention system as proposed by HORNE is an acceptable means under the DISTRICT's rules of treating runoff for water quality purposes. The bottoms of the ponds, as shown on the May 12 submittal, are all at least one foot below the orifice elevations, as required by the Basis of Review. Thus, the project met all relevant DISTRICT water quality requirements as of the May 12 submittal. Operation and Maintenance DISTRICT rules require that reasonable assurances be provided that the surface water management system can be effectively operated and maintained. HORNE will be the operation and maintenance entity for this surface water management system. The DISTRICT's main concerns at the time of permit review are that the design of the surface water management system not be an exotic design, that the design insure that littoral zones can be established, that the system orifice can be cleaned, that the overall system will be stable and that there is a viable operation and maintenance entity. HORNE's project can be effectively operated and maintained. Remaining District Rule Criteria As stipulated to by the parties that the project will not cause adverse impacts to wetlands and will not diminish the capability of a lake or other impoundment to fluctuate through the full range established for it in Chapter 40D Additionally, the proof establishes that the project will not cause adverse impacts on surface and groundwater levels and flows will not adversely affect the public health and safety; is consistent with the requirements of other public agencies; will not otherwise be harmful to the water resources within the District; will not interfere with the legal rights of others as defined in Rule 17 Objections Raised by the ASSOCIATES at the Hearing Pond Slopes and Operation and Maintenance Contrary to the assertion that the pond slopes will not be stable and cannot be effectively operated and maintained, the pond side slopes at this project are going to be constructed out of a heavy clay type of soil. Sodded side slopes of 1:1, as proposed for three of the ponds, can be stabilized and effectively operated and maintained. Although there is no DISTRICT requirement that sodded side slopes be mowed, so on these slopes could, if necessary, be cut. In the event the side slopes were to erode, easy repair is possible. All of the ponds except one side of one pond have areas at least 20 feet wide and slopes no steeper than 4:1 where maintenance can be performed. With regard to the pond that does not have this characteristic, equipment can enter and perform necessary maintenance. Water Quality Treatment Concerns that at least a portion of the bottoms of the ponds need to be below the seasonal high water table and that circulation of the ponds needs to be maximized in order to meet water quality treatment criteria are misplaced since there is no requirement that the pond bottoms be below the seasonal high water table in wet detention systems such as the one at issue in this case. Further, the entire bottoms of the ponds are littoral zone and meet DISTRICT rule requirements that 35 per cent of the pond be littoral zone, concentrated at the outfall. Additionally, the ponds at issue maximize circulation through the location of points of inflow and outflow. Floodplain Mitigation Concerns that volume in the floodplain mitigation area is not available because of problems with the seasonal high water table are also misplaced. Specifically, the floodplain area encroachment requiring mitigation relates to Pond 5A. There is more than enough volume within the area which will be excavated to compensate for the area where the fill will be deposited. The seasonal high water table will be at or below the floodplain mitigation area after the required excavation takes place. Although the seasonal high water table will be lowered where the excavation or cut is made and later raised where the fill is placed, no adverse effects on the water table will result from such lowering and raising of the water table. Volume In Pond 5A Allegations that the May 12 and 13 submittals reflect that Pond 5A has less volume available than the modeling calculations contemplate are incorrect. The changes in the contour lines of Pond 5A on the May 12 and 13 submittals from what was shown on the April 1 submittal occurred on the outside of the pond. The volume on the inside of the pond was not reduced actually increased when the pond bottom was lowered for water quality purposes. In determining how much volume a pond is to have when it is constructed, the computer modeling figures take precedence over the scaled plan drawings. In this case, the computer modeling figures never changed after the April 1 submittal. HORNE submitted a computer model that calculated the volume of Pond 5A. The output data clearly reflects that the top of the bank was 82 feet. Publix's Status as an Existing Site Assertions that the Publix site should have been considered in its pre-developed state since there will be approximately one acre foot of volume of runoff, or possibly less, leaving the site without retention are without validity. The Publix plaza was permitted by the DISTRICT in 1985 and constructed in 1986. The amount of peak flow discharge and overall discharge is currently authorized by a valid MSSW permit. When the DISTRICT reviews a permit application, all existing permitted surface water management systems must be accepted in their present state. There is no authority in the DISTRICT's rules to consider an existing permitted site in its pre Even if the Publix site is considered in its pre project has only .02 of an acre foot more volume of runoff in its post-developed condition than in the pre Storage of 100-Year Volume Allegations that the amount of 100-year volume being retained on site in the ponds has been incorrectly calculated by the DISTRICT and HORNE are also invalid. The DISTRICT's rules require that the difference between the pre- and post-development volume for the 100-year storm be retained on site. In the ponds which are the subject of this proceeding, the 100-year volume is retained in the ponds below the orifice. This volume cannot leave the site through the orifice; it can only leave the site by percolation into the ground or evaporation into the air.
Recommendation Based on the foregoing, it is recommended that the Southwest Florida Water Management District enter a final order granting HORNE's Application for Surface Water Management Permit No. 400317.02. RECOMMENDED this 25th day of June, 1993, in Tallahassee, Florida. DON W.

Findings Of Fact The land here involved is located at the southern end of the Acme Improvement District. The northeastern portion of the tract is owned by Petitioner Leonard H. Tolley, and comprises some 15 percent of the total acreage of the tract. The remainder of the tract is owned by Petitioner Strazulla Brothers. The entire tract includes Sections 3 and 4, Township 455 Range 41E and a parcel of land in The Township 44 1/2 S Range 41E adjacent to Sections 3 and 4 and comprises some 1400 acres. The Strazulla property was acquired by Warranty Deed from the Trustees, Internal Improvement Trust Fund, by Philip Strazulla and subsequently conveyed to Petitioner. In 1978 real property taxes on the Strazulla property here involved was $17,453.42. The tract is bounded on the west by the L-40 levee and canal, on the north by Acme Improvement District Dike and C-27 Canal; on the east by property owned by Miller American Industries and on the south by property owned by the South Florida Water Management District. By this application Petitioner proposes to place levees with their borrow canals on the east and south sides of the tract and to construct a 240 acre reservoir adjacent to the L-40 levee by erecting a reservoir retention levee some 1400 feet eastward of the L-40 levee. By installing a 100,000 gallon per minute pump station at the southeast corner of the proposed reservoir, the water presently standing on the property could be drained allowing the eastern portion of the tract to be converted to agricultural use and the remainder converted into 2.5 acre residential sites. The 1972 Palm Beach County land use plan recommended the area here involved be zoned Preservation/Conservation, which effectively precluded development of the property. At that time, Strazulla attempted to sell the property or trade it to a governmental agency for property that could be developed, but without success. In 1978, the Palm Beach County Land Use Advisory Board changed the 1972 land use recommendation to Residential Estate to allow a reasonable use of the property. (Exhibit 7). The property abutting Petitioners' property to the north has been drained and thereon is located an orange grove and, west of the orange grove, 5- acre residential homesites. The property to the east is being developed as residential homesites. The property west of the C-40 canal comprises the Loxahatchee National Wildlife Refuge consisting of some 221 square miles of traditional Everglades wetlands. The property to the south is owned by the South Florida Water Management District and is of a character similar to Petitioners' property. Some two to three miles south of Petitioners' property is an east-west canal. In 1900 the property here involved was located in the eastern part of the Florida Everglades and received the sheet flow that characterized the natural Everglades. This historic hydroperiod has been disrupted by levees at Lake Okeechobee and by various drainage and irrigation canals constructed to render the large tracts of land thereby drained suitable for agriculture. In the immediate vicinity of the property, the L-40 levee and canal, which enclose the Loxahatchee National Wildlife Refuge (hereafter referred to as the conservation area) form a barrier to any sheet flow from this property onto the conservation area. This levee and canal bars practically all interchange of waters between Petitioners' property and the conservation area and is in the process of destroying part of the historical eastern boundary of the Everglades. Erection of the proposed levee on the east and south boundaries of the property would effectively stop the drainage now coming to this property from the east and the drainage from this property to the southeast. The South Florida Water Management District (SFWMD) owns a right-of- way to the east of the L-40 levee which is located in the area proposed by Petitioner for its reservoir. Petitioners' application to encroach on this right-of-way with the proposed reservoir was denied by SFWMD. This denial was based on the environmental impact, county zoning regulations (since changed) and the as yet undetermined effect of back pumping into the conservation areas. (Exhibit 17). Specifically, SFWMD Staff Report (Exhibit 17) found the environmental impact of the project will be: This proposed truck farming operation and residential development will destroy approximately 1100 acres of valuable wetland habitat by drainage. The impact on the 240 acres (60 acres of SFWMD right-of-way) of emergent marsh within the proposed reservoir will be determined by the water level management of the impoundment. A drastic change in water depth or inundation period could result in severe alterations of the present wetlands. An additional 50 acres of marsh will be lost due to dredge and fill operations for levee construction. The entire tract is poorly drained and is under water for considerable portions of the year, with the westernmost portion containing the longest periods and greatest depths of standing water. The soil in the eastern portion of the property is predominantly sandy, with a gray sandy loam layer at depths of 20 to 40 inches. The soil in the central portion of the tract is predominantly sandy, with a gray sandy loam layer at depths greater than 40 inches. The soil in the western portion of the tract is sandy, with a black organic surface layer (muck) 8 to 15 inches thick, underlain by gray sandy layers. Vegetation in the property goes from some pine and cypress in the eastern portion to sawgrass marshes in the western portion, with numerous varieties of plants associated with wet soil and marshy areas. During the proposed construction adequate safeguards can be imposed to prevent excess turbidity from entering State waters. This property comprises a large tract of pristine Everglades habitat for both plants and animals, and is of great value to the ecology of the state. In its undeveloped state it provides a buffer zone of up to two miles eastward for the conservation area. Water presently on the property is predominantly rainwater and of better quality than the water in the C-40 or C-27 canals adjacent to the property. Use of the land for agricultural purposes would increase the risk of water quality degradation caused by water runoff carrying fertilizers, herbicides and pesticides into the proposed reservoir and/or perimeter canals. If excess water on the property is pumped into the C-40 or C-27 canals, degradation of those waters could occur. The proposed development was opposed by the Florida Game and Fresh Water Fish Commission, not only because it would remove these fresh water marshes from the ecosystem and take away an essential habitat for birds and aquatic life, but also would remove a surface water retention basin and vegetation filtration of runoff from adjacent uplands. (Exhibit 16). The Permit Application Appraisal Report (Exhibit 15) which recommended denial of the application found the property acts as a buffer between the agricultural lands to the east and the conservation area and development as proposed would remove this buffer; and that water quality standards may be degraded due to agriculture runoff from the developed property being pumped into C-40 canal. Specifics of how runoff from property would be controlled were not obtained by the Environmental Specialist who prepared Exhibit 15. Pumping the surface waters on the property into a reservoir would reduce the diurnal variation in dissolved oxygen levels in the water and thereby improve water quality from that aspect. Water in the reservoir would be of greater depth than presently exists, thereby reducing photosynthesis and its concomitant benefits to the water quality. On the other hand, the greater depths could result in fewer grasses and more open surface water, thereby allowing more aeration of the water by wind action. Herbicides degrade fairly rapidly, and holding them in a reservoir would allow time to degrade. Many pesticides are water insoluble and would settle to the bottom of the reservoir.
Findings Of Fact Joyce K. Anderson and Thomas Barnett have filed an application for issuance of a permit to dredge and fill a small area in the littoral, or "near shore," zone of Gillis Pond, a "sandhill lake" lying in what is known as the "sandhill region" of Central Florida, generally northeast of Gainesville. The dredging and filling as now proposed would be on and waterward of two lakefront lots jointly owed by the permit applicants. They seek by their application, authorization to dredge and fill at only one site on the waterward margin of the two lots with that modified project area reduced in size to a dimension of 12 feet by 25 feet. Fifteen feet of the project would be waterward of the shoreline. The Respondent, the Department of Environmental Regulation, is an agency of the State of Florida charged with the duty of enforcing, as pertinent hereto, the provisions of Chapter 403, Florida Statutes, and Chapter 17-3 and 4, Florida Administrative Code, enforcing the water quality standards contained therein as they relate to dredge and fill projects of this sort, with concomitant permitting jurisdiction over such projects. The permit applicants desire this dredge and fill permit in order to make a safe, comfortable swimming area for Mrs. Anderson's family and friends. Mrs. Anderson desires to remove the tree stumps, roots and vegetation existing in the littoral zone area of the above dimensions in order to make access directly from the shore more comfortable and pleasant, especially for small children who are unable to swim in the deep water off the waterward end of the existing dock. Mrs. Anderson already has a 56 foot dock extending from her property into the lake. The water is 7 feet deep at the waterward end of the dock and the littoral zone containing aquatic vegetation extends beyond the length of the dock in a waterward direction. The project area would extend waterward of the shoreline, a distance of 15 feet, and would parallel the shoreline approximately a distance of 12 feet. The littoral zone vegetation at the site, however, extends waterward from the shoreline 50 to 60 feet. The proposed area to be dredged is quite small in size in relation to the total linear shoreline of the subject lake of approximately 4,000 feet. The dredged material would be excavated to a depth of approximately 6 inches over that 12 by 15 foot area and replaced with clean sand fill. The dredged material removed from the site would be secured on an upland site such that nutrient pollutants from that dredged material could not be leached or carried back into the lake through storm water runoff. Approximately one-third of the shoreline of the lake is bordered by a marsh or wet prairie which is approximately as large in area as the lake itself. The dominant vegetative species in the project area and surrounding the lake, including the marsh, are submerged freshwater species listed in Rule 17- 4.02(17), Florida Administrative Code, including maidencane, sawgrass and a rare aquatic plant, websteria confervodies. Gillis Pond is a Class III water of the state, although its water quality parameters, or some of them, clearly exceed in quality, the minimum standards for Class III waters. Gillis Pond is what is termed an "ultra- oligotrophic lake, which means that its waters are characterized by a high level of transparency and very low nutrient content, that is to say that they are essentially pristine in nature. An oligotrophic lake such as this is very sensitive to any addition of nutrient pollutants. Even a small addition of nutrients to such water can cause an imbalance in the fauna and flora which have evolved to become dependent upon a low nutrient aquatic environment. Specifically, the rare aquatic plant named above is very sensitive to any enhanced nutrient levels and thus serves as a barometer of the water quality in this body of water. The addition of any nutrient pollutants to the lake, even in small amounts, might alter the chemical balance of the water in a derogatory manner so that the websteria confervodies might be eliminated. The elimination of this species from the littoral zone vegetation band surrounding the lake would likely result in other forms of vegetation supplanting it, altering the balance and makeup of the community of fauna and flora native to the lake and possibly hastening the progress of the lake toward eutrophication and degradation. The present water quality in the lake is such that dissolved oxygen and other criteria are better than the Class III water quality standards. The vegetation in the littoral zone of the lake and extending out as much as 50 to 60 feet waterward performs a significant function in uptaking and fixing nutrient pollutants that wash into the lake from storm water runoff from the surrounding uplands. Inasmuch as 30 to 40 feet of this belt of littoral zone vegetation would remain waterward of the dredged and filled area if the permit is granted, the nutrient uptake function of the vegetation in the littoral zone would not be significantly degraded. There are two locations where littoral zone vegetation has been removed in a similar fashion and water quality and flora and fauna communities characteristic of an oligotrophic lake are still present and healthy. Further, there is an extremely low nutrient level in the lake at the present time, and no significant amount of nutrient pollutants are leached or washed into the lake through septic tanks, storm water runoff or other sources. There is no question that the project as proposed would result in some slight, transitory degradation of water quality in the form of increased turbidity and reduced transparency. Turbidity will be caused during and shortly after the dredging and filling operation itself, caused by stirring up of bottom peat or sediments and by removal of a 12 by 15 foot area of aquatic vegetation in the littoral zone of the lake. Turbidity curtains in still waters such as involved here, can substantially reduce the spread of turbidity caused by the stirring up of bottom material and can substantially reduce the period of its suspension in the water by containing it at the dredged site. The vast majority of the littoral zone vegetation surrounding and waterward of the area to be dredged will remain such that the nutrient uptake function will be essentially undisturbed, thus any adverse impact on water quality will be insignificant. In terms of cumulative effect of allowing a multiplicity of such projects, not even a 10 percent loss of the littoral zone band of vegetation in the lake, which would be the maximum possible loss if all riparian land owners were allowed a similar size dredged and filled area on the front of their lots, would cause a violation of Department water quality standards. Parenthetically, it should be pointed out that such riparian owners cannot be prevented by any water quality criteria in Chapter 403 or Chapter 17, Florida Administrative Code, from having access to the lake in front of their lots. Such human traffic will have the gradual affect of destroying a significant amount of the littoral zone vegetation on and waterward of those lots (which is a cause and result the Department is powerless to regulate). By confining the destruction of littoral zone vegetation to such a small area as that involved in the application at bar and thus guaranteeing adequate, comfortable access for the riparian owner, the survivability of the remaining critical littoral zone vegetation will be significantly enhanced.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence in the record and the candor and demeanor of the witnesses, it is, therefore RECOMMENDED: That the application of Joyce K. Anderson and Thomas Barnett for a dredge and fill permit as described in the modified and amended application be GRANTED; provided, however, that turbidity curtains are used during all dredging and filling activity and for a reasonable time thereafter until turbidity caused by the project has settled out of the water column.

Findings Of Fact Existing Conditions Between 1952 and 1957 the United States Army Corps of Engineers (Corps) and the Florida Central and Southern Flood Control District (the forerunner of SFWMD) constructed a chain of levees, L-1, L-2, L-3 and later L-4 in eastern Hendry County, Florida. These levees which begin approximately 10 miles to the southwest of Lake Okeechobee run first east, then south and then east again for a distance of approximately 38 miles. The purpose of these levees is to shield the land5/ to the east of them from the natural sheet flow of water which comes from the west during the area's rainy season. The EAA which is protected from natural flooding consist of rich muck soils which have been successfully exploited for years by sugar cane farming. The present levees were created by excavating a "borrow" canal parallel to the southern and western sides of L-1, 2, 3 and 4. The borrow canal is no larger than was required to provide sufficient material for construction of the levees; nevertheless, the canal has a considerable water carrying capacity in the amount of 1,260 CFS 6/ at peak flow. The canal is a navigable fresh water of the state. It interconnects into other navigable canals which terminate in either Lake Okeechobee or the Miami River. The water carried by the borrow canal flows south and discharges into the Miami canal via either a pumping station designated S-8, or via the borrow canal next to L-28.7/ The water which enters the Miami canal ultimately travels to canal C-60 and then into the section of WCA-3 south of Alligator Alley (State Road 84). Flooding The rain water which once moved from west to east directly across the eastern portion of Hendry County, Florida into the EAA is now interdicted by L- 1, 2 and 3. As a result it ponds in the corner of the intersection of L-1 and L-2 (known in these proceedings as the L-1 angle). The area flooded is grass land used by Hendry County ranchers for the open grazing of beef cattle. Some of the pasture is improved, that is fertilized, but the majority of the area is unimproved range. During flood times the ranchers move their cattle to alternative pastures either to the north or to the west. The deepest flooding, when it occurs, is immediately next to the levees in the L-1 angle. The flooding has been known to reach depths as great as 10 feet and to extend westward for several miles. Because the land to the west of the L-1 angle is higher, the depth of the flooding decreases in a westerly direction. The duration of the ponding immediately in the L-1 angle has been as long as 80 days after a prolonged and heavy rainfall event. This flooding occurs despite the capacity of the borrow canal to remove 0.18 inch of flood water per day from the inundated area. When there is flooding in the L-1 angle there is also high water In the northeast corner of WCA-3A where some of the water from the borrow canal is presently discharged. During a dry season the land immediately adjacent to the present borrow canal suffers overdraining due to seepage of ground water into the canal and its resulting evaporation or conveyance south. Water Conservation Area 3A is part of a series of conservation areas established as their name implies to conserve water. Extending over portions of several South Florida counties including Palm Beach, Broward and Dade, they provide the recharge source for the Biscayne Aquifer and other aquifers which are the water supply for metropolitan South Florida. The water conservation areas are also wildlife refuges and provide natural habitats for numerous South Florida animals such as deer, alligator, and wading birds. Description of Project The Hendry County plan as described by the Corps in General Design Memorandum No. 2, 8/ envisions the construction of a flood control canal, C- 139, with two water flow control structures, S-239 and S-243. To create C-139, the Corps plans to further excavate the existing borrow canal next to L-2, L-3 and L-4 for a total distance of 37 miles. See Illustration I.* This excavation will result in the removal of 5.2 million cubic yards of earth and limestone. Some of the resulting spoil will be used to create a levee along the west side of C-139. Most of the excavation will be done by draglines on the canal banks. Upon its completion C-139 will be an immense water conveyance. At its northern end the canal will be only five feet across the bottom with a depth of 10.6 feet, but by the time the canal reaches WCA-3A it will have enlarged to a bottom width of 80 feet across and a depth of 19.5 feet. Its peak design capacity is 3,000 CFS. That is more than twice the present capacity of the existing borrow canal. Downstream from S-239 C-139 turns south to be designated C-139(S) and to gradually become increasingly shallower. This will cause a discharge pattern designed to create a sheet flow across WCA-3A. Benefits, Future Land Use It appears that when levees L-1, 2 and 3 were constructed the Corps failed to fully consider the adverse effect which would result from the impoundment of water by the new levees. According to the General Design Memorandum, Levees 1, 2, 3 and 4 were constructed in the mid 1950s to prevent flood waters originating on the then sparsely developed lands westward of the levees from contri- buting to flooding on the rich agricultural lands lying to the east of the levees. The original borrow canals were sized based on materials needed for the levee construction. The sparse economic development of the lands to the west precluded increasing the con- veyance capacity of these canals to prevent flooding on those lands. Construction of the levees and the subsequent increased de- velopment over the drainage area have aggra- vated flooding problems on the lands. Water stands on some of the land during practically the entire wet season virtually every year. As the landowners developed the land, they became increasingly vociferous about con- struction of works to alleviate the flooding for which they contend is project-induced. There is merit in their contention in that the adjacent project works adversely affected both depth and duration of flooding in the area west of Levees 1, 2 and 3. (Emphasis added) The facts presented at the instant final hearing are somewhat to the contrary, in that there was no showing of significant subsequent development west of the levees after their construction. For many decades vast family ranches have raised cattle on the mentioned lands as they continue to do today. The primary purpose of the proposed project is to now provide flood control to an approximately 261 square mile drainage basin west of the flood-causing levees.9/ With a design capacity of 3,000 CFS, C-139 can handle twice the water which drains through the present borrow canal. By way of comparison the present canal has a drainage capacity of .18 inches per day from the flooded area during a ten-year flood,10/ while C-139 has the capacity to drain .43 inches per day. This heightened discharge rate will cause land in the L-1 angle to flood less, and once flooded, to be underwater for a shorter period of time. For instance, an area which during a ten-year storm might have been submerged for 40 days prior to the construction of the project Is estimated to have an inundation period of only 10 days upon the project's completion. The significance of the reduced flooding to the landowners in the flooded area is difficult to gauge from the evidence. Because an intensification of land use would result in a lowering in the quality of the water which runs off the land and into C-139 and thence into the environmentally sensitive water conservation area,11/ the landowners supporting the project were understandably reluctant to testify that the project will allow them to use their land for more than continued cattle grazing. The testimony of Mr. Joe Hillard, a partner in Hillard Bros. of Florida, Inc., one of the larger ranches is illustrative: Q If this project, the flood control portion, were built, would your company change any of its land uses on this land that you described? A No, sir, not at all. Not with what I understand is going to be done with the project I wouldn't change anything. In response to the Hearing Officer's later inquiry, Mr. Hillard explained that the project would allow pasture land to be used for twelve months per year as opposed to the current nine months per year during a flood season. He does not anticipate grazing any more head per acre after the project. This evidence contrasted with the assumptions made by the Corps in that part of the General Design Memorandum which discusses the cost-benefit ratio of the project. The Memorandum states at p. 52: As noted previously, the existing activity within the area is predominately agricultural with major emphasis in beef cattle production. Local landowners and managers were asked to indicate the production changes they expected to make with the reduced flood hazards available under with (sic) project condi- tions. These expectations were prepared as a land use map with the basic control matrix. For the most part, these changes in land use represented more intensive types of agricultural cultivation. In some cases, existing beef pastures were expected to be replaced with sugarcane, truck crops, and citrus production. The majority of the changes were an upgrading of existing beef cattle operations. Such upgrading was affected (sic) by planting the more pro- ductive types of pasture such as clover and grass combinations, and the application of additional fertilizers and supplemental water. These expectations were assumed to exist under favorable cultivation conditions. Because of the nature of soil conditions in the project drainage basin, sandy with poor nutrient and water retention ability, it is unlikely that land use in the 261 square mile drainage basin will change significantly. As predicted by Mr. Hillard, it is likely that all the project would do is allow more grazing time on land which is now periodically flooded. Since it is not the function of this proceeding to inquire into whether the purported cost- benefit ratio of the project is accurate, no findings will be made concerning that issue. Project Permitting History The Hendry County portion of the Central and Southern Florida Flood Control project for flood control west of levees 1, 2 and 3 was authorized by the Congress of the United States in the Flood Control Act of October 27, 1965. The Army Corps of Engineers is the actual builder of the project, but SFWMD is the local sponsor and is the Corps' agent in applying for the necessary permits from DER. The Department as the permitting agency is in a curious position here. Its Bureau of Water Resources (BWR) was responsible for the State Public Works Program through which Florida requested Congress to fund the Hendry County Project. Mr. Charles Littlejohn who was head of the Bureau in 1976 had the responsibility of lobbying in Washington for funding of the project. The DER through its Bureau of Permitting is now asked to pass on the validity of a project which the BWR has so vigorously promoted. The Department's uncomfortable posture was recognized by its permitting staff. In a memorandum dated March 9, 1979 to Mr. E.D. "Sonny" Vergara, Mr. Forrest Fields at DER wrote: I told Mr. Brown, as I told you yesterday that I felt rather awkward in reviewing for permitting a project which the agency had endorsed for the public works list." Every year projects being sponsored for federal approval are reviewed by a process In the Division of State Planning called the A-95 Clearinghouse.12/ The Hendry County Project had a checkered history there. Serious objections concerning the environmental impact of the project were raised; nevertheless, DER through the BWR continued to seek and was successful in obtaining federal funding. On November 15, 1978, SFWMD filed an application with DER for the requisite permits to begin construction. During the course of DER's review of the project several issues arose between the parties. Among them were: Whether local approval pursuant to Section 253.124, Florida Statutes would be required? Would an exception from dissolved oxygen (DO) standards be necessary? Whether local water quality standards would apply if they were stricter than state standards? Local Approval As early as February 19, 1979, DER noted that plans submitted by the applicant proposed the placement of fill in waters of the state. In a letter to Mr. Lee M. Brown of SFWMD, Mr. Forrest Fields, the DER permit processor, observed: Second, on page 2/11 of your drawings, you indicated that approximately 5,800 cubic yards of fill material will be placed water- ward of ordinary mean high water. I pre- sume that this fill is associated with structures S-243 and S-239. Pursuant to Section 253.124, Florida Statutes, approval of this filling by resolution of the local government is required. To do this I will, upon receipt of the Department of Environ- mental Regulation field report, summarize and send this to the Hendry County Commission. The Commission will have to consider this report, and, by vote, adopt a resolution approving the project. I will send you a sample resolution. The requirement of local approval was reiterated numerous times. In March, 1979, Mr. Fields sent a staff report of a biological survey of the project to the Hendry County Commission for consideration in their approval of the project. During a meeting on March 21, 1979 in the DER Secretary's office representatives of SFWMD were told that local approval would be required. On April 10, 1979 the County Commissioners of Hendry County gave their approval to the project. In correspondence to Mr. Charles Lee of the Florida Audubon Society, Secretary Jacob D. Varn noted that the permit applications were still incomplete because local approval for filling associated with the two water control structures had not yet been received by DER. During a public meeting held on May 22, 1979, the County Commissioners of Broward County, after three and one-half hours of testimony, voted 6-0 against approving the project as it related to fill in Broward County. Subsequent to that vote the Corps and SFWMD asserted that local approval by Broward County was not required. In response to this assertion Mr. Charles Littlejohn, on behalf of the Secretary, requested a legal opinion from DER's General Counsel. On October 30, 1979, General Counsel's Legal Opinion 79- 72 concluded that the Department could assert Chapter 253 jurisdiction over the project and therefore "local approval" is a statutory requirement for its permitting. On March 17, 1980 Mrs. Evelyn Jackman of Jackman and Sons, Inc., one of the major ranchers in the project drainage basin, wrote to Governor Graham to urge the rapid approval of the project. Her correspondence was forwarded to DER for an appropriate response. Ms. Victoria J. Tschinkel as Assistant Secretary noted in her reply on April 3, 1980 that: Pursuant to Section 253.124(3), Florida Statutes approval must be obtained from the County Commissioners before we can complete the processing of a permitting application for fill in navigable waters. Approval has not been received from Broward County and there Is fill proposed for the Broward County portion of the project. Ms. Tschinkel did, however, assure Mrs. Jackman that: The Department of Environmental Regulation is sympathetic to the problems outlined in your letter, and for that reason the Depart- ment has made this project part of its public works package given each year to Congress. We still support this as a public works pro- ject and for that reason we are attempting to work out the permitting problems as ex- peditiously as possible. Shortly after Ms. Tschinkel's letter was sent there was another meeting in the Secretary's office to discuss the project. Mr. Lotspeich's interoffice memorandum outlines the Department's new position as it related to local approval. In addition, the issue of what constituted fill pursuant to Chapter 253, Florida Statutes, for local approval purposes was discussed. Helen Setchfield also partici- pated in this discussion. After Helen and I looked more closely at the project, it appeared that only a concrete structure (S-239) was to be placed waterward of OHW.13/ We both agreed that in past permitting practices we had not required local approval for the construction of structures waterward of OHW, but only when fill to extend existing lands or create new lands was involved. Since the application drawings did not clearly show the relation of the fill and structure relative to OHW and sheet 2 of 11 clearly indicates that fill will be placed "below MHW" Forrest must have assumed that local approval would be required if the canal was determined to be under Chapter 253, Florida Statutes jurisdic- tion. GCO-79-72 from Randie Denker indicated that the Department can assert Chapter 253, Florida Statutes jurisdiction in the canals and therefore local approval would be required. It would appear that there was really no clear understanding as to what the "fill" consisted of in the case of structure 239. Conversation with Mr. Walker [counsel for SFWMD] and Messrs. Parsons [counsel for Alico and other landowners] and Davis [SFWMD] indicated that there was no intention to place fill in the canal waterward of OHW and that the concrete structure would span the entire canal width. Since the application drawings did not clearly show the relation of the structure and fill re- lative to existing OHW, Mr. Walker said he would provide new drawings which would show this. Helen and I discussed the situation and we scheduled an appointment to talk the problem over the (sic) Terry Cole. It was agreed at the meeting that simultaneous "intent" letters would be sent on May 5, 1980 from permitting and the exception review people. May 16, 1980 DER entered into a Stipulation with SFWMD which states in its entirety: The SOUTH FLORIDA WATER MANAGEMENT DISTRICT and the DEPARTMENT OF ENVIRONMENTAL REGULA- TION for purposes of this proceeding hereby stipulate and agree that: The DEPARTMENT OF ENVIRONMENTAL REGULA- TION has jurisdiction under Chapter 253, Florida Statutes, to require permits autho- rizing construction and other activities described in the application which is the subject of this proceeding. None of the activities or construction, including the construction of the proposed Spillway S-239, as described in the appli- cation which is the subject of this pro- ceeding, constitute construction of islands or an addition to or extension of existing lands and islands so that approval of local governments as described in Section 253.124, Florida Statutes, is not required. This Stipulation is executed by counsel for each party on the date shown. On May 20, 1980 coordinated letters of intent to grant permits for the construction of the project were issued. Pursuant to the Stipulation local approval was no longer being required by DER. Alternative Site Specific Criteria After receipt of SFWMD's permit application for the construction of C- 139 and associated structures, DIR noted that it did not have adequate data on dissolved oxygen. In correspondence dated March 9, 1979, Mr. Forrest Fields said: Fourth, the dissolved oxygen data are not adequate. The available data were col- lected during daylight, only, and these data include occasional concentrations of less than 4.0 mg/l. In an effort to re- solve these deficiencies so that reasonable assurances may be provided, you, Walt Dineen, and I will discuss the South Florida Water Management District data on Thursday, March 15. The results of the March 15, 1979 meeting were memorialized by Mr. Fields in a file memorandum dated March 19, 1979. The memorandum stated in pertinent part that: On March 15, 1979, Mr. Lee Brown, Mr. Walt Dineen, and Mr. Fred Davis, from SFWMD, called to discuss the staff's request for "reasonable assurance" re. the Department's water quality standards. Mr. Davis, the applicant's chief chemist, said that, throughout the Everglades, in both canals and conservation areas, the water quality standards for both conductivity and dis- solved oxygen are frequently violated. He asserted that this is typical of the area. He believes that these data represent natural background. The situation regarding affirmative, reasonable assurance appears to be this: widespread and frequent observations of DO data which are less than the minimum for Class III waters commonly occur within the existing L-1, L-2, L-3 canals. The increase in depth associated with C-139 is predicted to exacerbate existing stress- es on the DO regime.... However, the SFWMD's response does not constitute reasonable assurance re. other Class III standards. The District's DO and conductivity data may conceivably supply assurances that these standards will be violated in C-139. (Whether background DO and conductivity violate the standards may become important.) The District appears to have two alternatives: 1) attack the Class III standard; 2) apply for variances for, at least, DO and conductivity. A follow-up meeting was held on March 21, 1979. Again, in a file memorandum dated March 28, 1979 Mr. Fields wrote: Consideration of reasonable assurance began at the March 15, 1979, conversation among Messrs. Brown, Davis and Fields. According to the SFWMD, widespread and frequent violations of the Class III water quality standard for dissolved oxygen, as contained in Chapter 17-3, F.A.C., occur throughout the Everglades, in the canals, agriculture areas, Lake Okeechobee, and the conservation areas. The existing borrow canals follow this pattern. The SFWMD alleges that this condition is natural back- ground. They agree that it is probable that any existing DO stresses exist in the borrow canal will be exacerbated in the proposed C-139. However, both the former and present editions of Chapter 17-3 F.A.C. allow for exceptions for natural background. The SFWMD will review these rules to determine which regulatory approach will be taken. In addition, the SFWMD will supply to DER data for the "benchmark" station in the L-28 canal and at Everglades National Park to demonstrate lower back- ground concentrations of DO. Furthermore, the SFWMD will apply, per Ch. 403.087, F.S., for a temporary operating permit for the completed structure. Conditions governing private connections and incor- porating BMPs may be included in the TOP. On April 5, 1979, SFWMD submitted in support of its original permit application a document called Evaluation of Natural Background Dissolved Oxygen in Conservation Area 3-A, South Florida. This evaluation received unfavorable reviews at. DER. Landon P. Ross, chief biologist, wrote in an April 9, 1979 memo that: I have reviewed the data provided by SFWMD regarding background DOs in the Everglades area and have the following comments: Indication that DOs are not harmful to local organisms are, in a legal sense, irrelevant to the question. The data provided give evidence of the occurrence of low DOs in the area. Since the measured low DOs seem to be from artificial drainage channels, they can hardly be supposed to be "natural". The measures that SFWMD provided, however, do not seem too different from the values that I would expect to find in a natural swamp habitat. The proposed "standard" cannot be logically derived from the DO measurements provided. This Evaluation was later submitted in support of first Petition for Exception noted infra. In his review of the data Mr. Fred Bartleson at DER wrote:14/ The data submitted by the South Florida Water Management District does not justify the requested exception for dissolved oxy- gen criteria for the Hendry County Project. The petition alleges that D.O. concentra- tions lower than 1.0 mg/l occur in the re- ceiving waters of Conservation Area 3A. However, the data submitted from that area indicate a minimum value of 2.3 mg/l. The value cited in the petition of less than 1.0 mg/l was recorded in the L-3 borrow canal adjacent to the conservation area. This canal drains an agricultural area. Similar data from the L-28 east canal which is less affected by cultural activity depicts minimum D.O. values between 3 - 2 mg/l. The low D.O. values found naturally in fresh- water wetlands during the warmer months ob- viously result in stress to the biota. The introduction of larger quantities of water from the proposed Hendry County Project, which is anticipated to have lower D.O. values as well as nutrients and pesticides from agricultural runoff, could adversely affect the ecosystem. The proposed exception allowing discharge of water with not less than 1.0 mg/l for more than two consecutive hours in any 24-hour period is arbitrary and not supported by data. It may well be that an exception could be granted for some lowering of the D.O. criteria with time constraints. However, more defini- tive and conclusive data are required to in- sure that this action would not cause adverse effects. The burden of supplying this infor- mation should rest with the petitioner. His views were supported by Messrs. Kevin Edwards, Vernon Myers, and G. J. Thabaraj. Mr. Edwards also noted the difference in DO readings between the WCA- 3A and the borrow canals. SFWMD filed a Petition for an Exception on July 23, 1979. The Petition alleged that the receiving waters of the proposed discharge are located in WCA-3A and that due to natural causes that portion of WCA-3A which will receive the discharge does not meet the state standards for DO as set out in Section 17-3.121, Florida Administrative Code. The DO levels of the proposed discharge are alleged to be similar to those levels already present in the water conservation area. In response to the Petition DER requested more information by a letter from Stephen Fox dated August 29, 1979. The letter requested: Data which supports the contention that the condition of the waters is the re- sult of natural causes, that is, there is an absence of man-induced alteration; or Data which supports the contention that the condition of the waters is the re- sult of man-induced causes which cannot be controlled or abated with technology or management practices. Data which supports the contention that the biota have not been adversely af- fected or will not be affected adversely. The data submitted with the application did not address the possibility that the low dis- solved oxygen levels may be caused by the practice of pumping water off the agriculture areas during the summer wet season. Compari- son with similar subtropical, undisturbed aquatic environment should be made. The dis- solved oxygen data should be compared with pumping schedules and with dissolved oxygen values of water pumped. Comprehensive water- shed and land use data is needed for a thorough review. Further, the data submitted did not support the contention in the petition of a corre- lation between C.A. 3A and canals L-3 and L-28. Also, the contention that in C.A. 3A dis- solved oxygen concentrations were below 1.0 mg/l were recorded was unsupported. The data array was not adequate in terms of distri- bution and frequency of sampling, to demon- strate that the dissolved oxygen regime ap- proaches the proposed alternative criteria. On October 2, 1979, E. D. Vergara summarized the status of the SFWMD application for the DER Secretary, Jacob D. Varn. His memorandum with respect to dissolved oxygen states: ... (permits) originally requested under old 17-3 rules, it was found quality assurances could not be made due to a naturally occurring condition of low DO. The Department requested information sup- portive of the low DO background, but due to differences in opinions among the biologists, the district elected to re- quest an exception under the provisions of the new 17-3 rule instead. Additional information has now been requested by the Department to support the request for an exception, and the District is cur- rently putting this together. It is the general feeling that with this additional data, granting the exception should be possible. SFWMD responded to Mr. Fox's letter above by submitting in the Spring of 1980, an Amended Petition for Exception from Criteria. In its Amended Petition the District abandoned the comparison, found in the original petition, of the proposed discharged waters' dissolved oxygen levels to the levels found in the water conservation district. Instead the District concentrated on a comparison of the dissolved oxygen levels in the proposed discharge waters to the levels in the relatively clean canals in the South Florida area, specifically the L-28 canal system. The District proposed that as an alternative to Class III standards the following criterion be established: During any 24-hour cycle the dissolved oxygen concentration within the photic zone shall exceed 1.0 mg/l, except during the extreme low point when values shall not be less than 1.0 mg/l for more than two consecutive hours. (Emphasis added) Accompanying SFWMD's Amended Petition was a report (Supporting Report) dated February, 1980, which provided a voluminous compilation of data to justify the alternative standard proposed.15/ On April 8, 1980, Ms. Helen Setchfield sent a memorandum to DER staff requesting that they review the Amended Petition and report back to her within five days. Also on April 8, 1980, after a meeting attended by both SFWMD representatives and DER representatives, it was decided that DER would issue coordinated letters of intent on May 5, 1980 for both the exception and the dredge and fill applications. In spite of the decision to issue letters of intent, DER permitting staff were not satisfied with the concept that ban-made canals were "natural" background or that the proposed DO standard was reasonable. On April 16, 1980, Rick Lotspeich wrote to Suzanne Walker, Chief of the Bureau of Permitting, that: I have reviewed the referenced "request for exception" and it appears that the petition and supporting report are suf- ficiently complete to allow evaluation of the merits of the request. It would appear that the proposed dis- solved oxygen standard of 2.0 mg/l over 24 hours and 1.0 mg/l "during the extreme low point" for not more than two hours, is excessively low and not warranted by the data presented. A review of the data from figures 4 and 5 generally indicate that the following standard would be appropriate: Dissolved Oxygen: The concentration should not average less than 4.0 mg/l in a 24-hour period and not less than 3.0 mg/l except during the months of June--September, when the concentra- tion shall not average less than 3.0 mg/l in a 24-hour period and never less than 1.0 mg/l. Later, after having received comments from Rick Cantrell and Bob Siciler, Mr. Lotspeich wrote to Ms. Walker the following: My recollection from reading the request for exception was that SFWMD had indeed recognized the fact that the canals and their design had contributed to the de- pressed DO values of the water in them. Pursuant to Subsection 17-3.031(1), Florida Administrative Code, there may be a consideration for "man-induced causes which cannot be controlled or abated I am in full agreement with Cantrell and Siciler's discussion of the adverse impacts that canals in general, and the specific canal involved in this project, have on water quality and biological resources. However, I disagree with the conclusions that they reached. Clearly, there are extenuating circumstances involved in this case which set it apart from other dredge and fill cases. In light of these circum- stances, the fact that the depressed DO levels have resulted from man-induced causes which cannot be controlled, and Cantrell and Siciler's own statement that approval of this project has little probability of worsening the existing water quality of L-2, L-3 and WCA-3, I would recommend that the exception be granted. However, the alternate DO standard which I recommended in my previous memo is still applicable. (Emphases added. The "extenuating circum- stances" were never explained.) Subsequently, on May 20, 1980, the Department issued a coordinated letter of intent to grant an exception but for the standard proposed by Mr. Lotspeich, not that requested by the Water Management District. Dissolved Oxygen and Exception Section 17-3.121(14), Florida Administrative Code requires that discharges into fresh waters of the state must exhibit dissolved oxygen concentrations of 5.04 mg/l or more. Normal daily and seasonal fluctuations above that level must be maintained. Dissolved oxygen in certain concentrations is required for aquatic life. The amount of oxygen contained in water is subject to numerous variables, many of which are interrelated. They include: amount of sunlight entering the water, ability of the water to transmit light, photosynthetic activity of aquatic plants, water temperature, mechanical oxygenation, mixing with other water which may have either a higher or lower dissolved oxygen content, depth of water, rate of oxygen consumption by resident biota, and time of day. It is undisputed that during certain seasons and times of day the water in the existing borrow canal does not meet the state dissolved oxygen standard. Readings as low as 0.9 mg/l have been obtained there. These low readings usually occur in the months of heavy rainfall, primarily July through September. See the data on Figure 4 of SFWMD's Supporting Report. Similar, though not so low measurements have been obtained in neighboring man-made canals such as L-28. L-28 has been used by water quality experts as a "benchmark" for canal water quality since it does not receive large amounts of runoff from agricultural areas where pollutants such as fertilizers are used. There are numerous times during a given year that the dissolved oxygen levels in L-28 are below the 5.0 mg/l state standard. It is also possible to find at least two locations in WCA-3A wetlands where dissolved oxygen readings are below Class III standards. At Gauge 3-2 in the northwest corner of WCA-3A near where the project would discharge, dissolved oxygen levels have varied from 2.3 mg/l to 10.8 mg/l; however, the mean value for the measured levels has been 5.5 mg/l as reported on Table 2 of the Supporting Report.16/ Unfortunately, the data regarding dissolved oxygen concentrations in the proposed discharge area are scant. This paucity was recognized by the Supporting Report which states at page 6: "No systematic study of the dissolved oxygen conditions or requirements for fresh water wetlands in general, or WCA-3A in particular, have yet been conducted." Despite the limited data on WCA-3A, certain comparisons between DO readings in it and in the borrow canal which would discharge into the area can be made. Readings taken at Gauge 3-2 do not sink to levels as low as those found in L-3. Compare Figure 4 of the Report to Table 2. The minimum readings taken in L-3 were during those periods of greatest discharge. If the discharge from the existing borrow canal were presently sent into the area of Gauge 3-2 during months of peak discharge, the waters entering WCA-3A would have a lower dissolved oxygen concentration than would exist naturally in the area. It is not surprising that water in the borrow canal exhibits unusually low dissolved oxygen levels. The levee sides limit reaeration which could occur due to wind movement. The surface-to-volume ratio is also unfavorable. Much oxygenation occurs at the interface between the water and surrounding air, but because the canal is relatively deep compared to its surface area, the proportion of water coming into direct contact with the air is low.17/ The depth of the photic zone, i.e., the section of water penetrated by light, is limited due to the naturally high color of canal water. Construction of C-139 will add somewhat to a lowering of dissolved oxygen levels in the entire canal water column. To increase its conveyance capacity, the existing borrow canal will be deepened significantly, particularly in its southern reaches. This deepening will result in a lowering of the ratio between the area of water surface to the depth of the canal. No mathematical data were presented by which the lowered ratio can be computed; however, an examination of Plates A-24 and A- 25 of the General Design Memorandum indicates that completed C-139 will contain a higher ratio of water below the photic zone than is presently contained in the borrow canal.18/ This is true only during those times when the canal is relatively full of water. As the canal level drops during a drought the photic zone will approach the canal bottom in the shallower sections. Both SFWMD and DER have proposed site specific DO alternative standards. These have been set out in the foregoing discussion of the permitting history. There is a significant difference between the proposals. SFWMD's proposal includes only the waters contained in the photic zone. It fails to recognize that during times of discharge, the waters of C-139 which are deposited in WCA-3A will not be only those of the photic zone, but will come from the entire water column of the canal. While SFWMD's standard might be acceptable for C-139 when it is in a no discharge state, the standard is completely unacceptable when the canal is discharging. Neither the standard proposed by DER nor SFWMD recognizes the difference between the dissolved oxygen regime which can be predicted for C-139 and that presently existing in WCA-3A. The data submitted would justify an exception from the present 5.0 mg/l Class III standard. There are certainly times when both the water existing in relatively unpolluted canals and in the water conservation area contain less than the present minimal content of dissolved oxygen. When C-139 is not discharging an exception, which would have a range now exhibited by the existing borrow canal, would be justified for the new canal. Sufficient data was not presented here to suggest the precise figures for such an exception. The information given for L-3 for instance, is compiled from samples taken only once during a given day. The water depth of the sample is not given. Accurate data would account for the diel variation and the effect of water depth on each sample. Without data which gives a daily average, it is impossible to determine if the water either standing in, or discharging from C- 139 will meet any proposed alternative criterion. For the same reason the data obtained for the present DO concentrations in WCA-3A is incomplete for establishing appropriate levels for discharge waters entering that area. The establishment of site specific alternative criteria must await the submission of more complete dissolved oxygen readings from the applicant. One of the elements in considering whether to grant an exception to established standards is whether the existing biota have adapted to the background DO levels. The proof here shows that the fish and other biota now living in the borrow canal either tolerate or have adapted to the present low DO regime there. It has also been proven that the biota in WCA-3A are tolerant of the naturally occurring low DO levels in that area. It was not shown how they would respond to a massive influx of low DO water when C-139 would be discharging. Hydroperiod in WCA-3A The northwest corner of WCA-3A, where C-139 and C-139(S) will discharge, has a higher ground elevation than that of the southern portion of the water conservation area. The highest elevation in the extreme northwest corner is approximately 17 feet above mean sea level (MSL). It tapers down to approximately ten feet MSL at the southern boundary of WCA-3A. The project is designed to facilitate the sheet flow of discharge water from the northwest area towards the southeast with an ultimate destination being flow into the Miami canal. The construction of the Miami canal, C-123, which runs on a northwest- southeast diagonal across the area, causes overdrainage of the northwest section. The borrow canal along Alligator Alley also contributes to excess runoff. This overdrainage has shortened the hydroperiod in the northwest corner from approximately 9 to 10 months to approximately 5 to 7 months. "Hydroperiod" is the span of time during which land is inundated by ponded water. The shorten hydroperiod has a profoundly destructive impact on the natural environment. The muck soil when not submerged oxidizes at an accelerated rate. At the present time the rate of oxidation in the northwest corner is more rapid than the replacement rate. Since the natural hydroperiod has been altered muck fires have been more severe and frequent. These fires destroy existing tree islands which dot the Prior to 1974 WCA-3A received discharges from the waters of the L-1, 2 and 3 borrow canal. The outlet of the canal at L-4 was determined to be inadequate for flood control purposes in the L-1 angle. To increase the discharge rate of the borrow canal culverts G-88 and G-89 were installed at the L-3/L-4 intersection in October of 1974. G-89 directs part of the flow from the L-3 canal into canal L-28 west, and then into pumping station 5-140 and into C- 60 (parallel to Alligator Alley). G-88 directs another part of the flow from the L-3 canal into the L-4 borrow canal and then into S-8 where it is pumped into the Miami canal. Rather than being allowed to flow in a shallow sheet across the water conservation area, the direct water flow is now sent southeast in canals for ultimate discharge outside the area. This waste would be eliminated by the proposal to have C-139 discharge into WCA-3A via C-139(S). There is no dispute that more water is needed annually in the northwest corner of the water conservation area. What is at issue here is the timing of placing additional water there. Generally when there is flooding in the L-1 angle and C-139 would be discharging at its maximum rate there is already flooding in WCA-3A. Rainstorm events are somewhat regional and cover both areas. The applicant estimates that if the volume of water discharged by C-139 in a two-week period were to be instantaneously spread over the northwest corner of WCA-3A 20/ it would raise the water stage by 0.4 feet. This would occur during a one in ten year storm. At that time the wildlife in the water conservation area would already be stressed by high water levels. A 0.4 foot increase in stage could kill deer and other terrestrial animals and destroy alligator nests, but it also could benefit the more aquatic animals. The result of this increase cannot be accurately predicted on the data supplied by the applicant.21/ While expert witnesses on behalf of the applicant were willing to express an opinion that the influx of drainage water from C-139 would be beneficial, the opinions were simplistically based on the unsupported assumption that because WCA-3A currently suffers from overdrainage, any additional water at any time would be beneficial. It is possible that those opinions were based on studies conducted which prove that a discharge of water such as will come from C-139 may create a beneficial increase in the marsh hydroperiod. Unfortunately, no evidence of the existence of such studies is in this record. The applicant's expert witnesses' opinions are therefore given little weight. In the present situation WCA-3A receives some water from the borrow canal during the dry season when additional water is most beneficial. At the expense of overdraining the land west of the borrow canal, ground water seepage now enters the canal and travels south through L-1, 2 and 3. After the construction of S-239, designed to prevent overdrainage, any possible flow into WCA-3A during dry periods will be cut off. No evidence was presented on what quantity of water WCA-3A will lose during a dry season due to S-239. Also the record does not reflect what effect that reduction will have on biota in the water conservation area. S-239 and Fill When the level of water in the borrow canal drops below the nearby water table, there is groundwater seepage laterally into the canal. If C-139 were to be constructed without any water control devices, it would exacerbate the overdrainage because it will be a far more efficient conveyance than is the borrow canal. S-239 has been designed to prevent this overdrainage. The structure will be located in Broward County. On May 22, 1979 the County declined to give its approval of the use of any fill, as the term is used in Section 253.124, Florida Statutes, for the construction of this project in Broward County. The Department of Environmental Regulation has not maintained a consistent unwritten policy on what is "fill" in navigable waters of the state.22/ Testimony from past and present Department employees indicated that at times a "use" concept was employed to determine what was fill. If additional dry land were created which would be used for commercial purposes, then the newly created land was called fill which required local approval. At other times use was unimportant. The test was whether or not the result of the additional material would be moving the point, at which the high water mark intersected the land, in a waterward direction. It is found that what constituted fill in past permit cases depended upon the personal interpretation of each Department employee. S-239 as proposed is a massive structure which will cost 1.32 million dollars 23/ to build. It will contain 11,000 cubic yards of fill and backfill; 530 cubic yards of 1' by 1' pieces of stone rip-rap; 1,230 cubic yards of concrete and 647,000 pounds of cement. 153,800 pounds of reinforcing steel will be required. The structure will be over 50 feet high and will span C-139 where it is 60 feet wide. Each of the two vertical lift gates which control the water flow will be 27 feet wide. See Illustration II.* In between them will be a concrete pier three feet wide and approximately 38 feet long. The cement bottom of the structure will rise from an elevation of 8.0 feet MSL to a crest of 3.3 feet MSL for a total height of 11.3 feet. In order to allow service vehicles to pass across the canal a bridge 13 feet wide will span from one bank to the other. This bridge will support large trucks. The stone protection provided for in the plans consists of 1 foot square pieces of rip-rap to be placed 40 feet immediately upstream from the control gates and 30 feet immediately downstream of the gates. The purpose of this protection is to prevent erosion of the canal bottom and sides where the water flows by at a relatively high velocity. The majority of rip-rap will be placed below the ordinary high water mark. Local Water Quality Standards The issue of local water quality standards arose late in the permitting process. DER had already issued two letters of intent to SFWMD before the Department gave consideration to standards promulgated by Broward County. It appears from the record that the Broward County standards were formally brought to DER's attention through the County's Petition for Formal Hearing filed on June 3, 1980. On June 26, 1980, DER issued an amended letter of intent which said: This letter is an amendment of the letter of intent to issue signed by the Department on May 20, 1980. In that letter, the Depart- ment stated: "This intent to issue is contin- gent upon the applicant being granted an exception from the criteria for dis- solved oxygen, for Class III waters, pursuant to Section 17-3.031, Florida Administrative Code." The preceding paragraph is hereby amended to include a provision that the applicant must obtain relief from the dissolved oxygen stan- dards that appear in Section 27-5.072(19), Broward County Code, through a variance or other legal mechanism, in addition to the exception from state standards for dissolved oxygen. Section 27-5.072(19), Broward County Code, states that DO is to have a "daily average not less than 5 mg/l; single reading never less than 4 mg/l. The May 20, 1980, letter also contained a paragraph that read: "However, should the Department grant an exception from the dissolved oxygen criteria pursuant to Section 17-3.031, Florida Administrative Code, the Division intends to issue the permit." This paragraph is hereby stricken and the following paragraph substituted: "If the Department grants an exception from the State dissolved oxygen criteria pursuant to Section 17-3.031, Florida Administrative Code, the Division intends to issue a conditional permit which will only become valid upon the granting of relief by Broward County from its existing local standards for dissolved oxygen." The Department is taking this position upon consideration of Section 403.182(6), Florida Statutes, which requires the Department to en- force all stricter or more stringent rules, regulations or orders in the jurisdiction where they apply. It is the Department's position that it is without discretion to grant relief from Broward County's local standard for dis- solved oxygen. By its Petition the County alleged that it has an approved local pollution control program and that the proposed project will violate its local standards for dissolved oxygen and nutrients found in Sections 27-117(b)(9) and 27-117(11) of the Broward County Code.24/ Neither SFWMD nor the Corps has applied to the Broward County Environmental Quality Control Board for either a license under Chapter 27 of the County Code or for a variance from the standards established therein. On April 20, 1972, the Florida Department of Pollution Control (the predecessor of the Department of Environmental Regulation) gave temporary and conditional approval for six months to the Broward County Pollution Control Program. This approval provided that the County has full authority to enforce its own laws, rules and regulations, provided that they must be as strict or stricter than those of the State. The County was also required to modify its rules if the State subsequently adopted the regulations in conflict with those of the County. On November 7, 1972, the Department of Pollution Control gave Broward County full and final approval pursuant to Section 403.182, Florida Statutes. Subsequently, in 1974 and 1976 the State and Broward County entered into new agreements. These agreements were the result of DER's desire to make uniform all its agreements with all qualified local programs. The Broward County pollution control program including the portion administered by the Environmental Quality Control Board, continues to be an approved local program as defined at Section 403.182, Florida Statutes.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That the Department of Environmental Regulation enter an Order denying South Florida Water Management District's application for a water quality permit and for a dredge and fill permit. DONE and RECOMMENDED this 13th day of October, 1982, in Tallahassee, Florida. MICHAEL PEARCE DODSON Hearing Officer Department of Administration Division of Administrative Hearings Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 13th day of October, 1982. * NOTE: Illustration I, noted in paragraph 8 and Illustration II, noted in paragraph 49 are not a part of this ACCESS document. Illustrationn II is available for review in the Division's Clerk's Office.
Findings Of Fact The applicant currently operates a 58 slip marina Village at the proposed site, which was constructed under a modified permit from the Department in 1980 by Sunset Realty. Subsequent to that construction, the Petitioner commenced its Marina Village project on uplands adjacent to the existing dock facility and entered into a lease with Sunset Realty to operate the present marina as part of its "Boca Grande Club." The operative portion of the existing marina, that is, where boats are moored and operate, is in water eight feet or greater in depth. The marina provides fuel service at a separate fuel dock as well as electric and telephone service at the individual slips, thus permitting boats using the slips to hook up to on- shore electrical and telephone service. Sewage pump-out equipment is available at the fuel dock and a portable sewage pumping facility is available to be moved to each slip as necessary. Boca Grande Club employs a full time dock master who lives aboard a boat at the existing facility. The facility presently generally serves larger craft, that is, boats generally larger than 25 feet in length and serves some vessels in excess of 60 feet in length. The marina village portion of Boca Grande Club is a condominium, residential development, which is nearly completed and will consist of 48 residential units. A second portion of the Boca Grande Club is located on the Gulf of Mexico some 2,000 feet away from the marina village. The entire project employs slightly more than 100 people. The Petitioner contends that the existing marina of 58 slips is not sufficient to provide adequate dock space for the residents of the development, as well as members of Boca Grande Club. It also contends that the existing dock elevations are such as to make access from small boats to the dock difficult. The number of residents or club members requiring boat slips was not established, nor was it shown that efforts to modify existing dock elevations have been attempted unsuccessfully. In any event, the Petitioner applied to the Department on February 15, 1985, to construct the approximate 3450 square feet of additional dock facility. This would include a "T" shaped structure with an access ramp or walkway extending approximately 189 feet toward the existing channel from the shore. The waterward "T" portion will be 237 feet ~n length. Additionally,. an "L" shaped structure with two sections, each approximately 75 feet in length, would be constructed which would accommodate six boat slips. The "T" shaped dock will accommodate 19 boat slips at its waterward end. The docks proposed will contain ten 3' X 15' finger piers with regard to the "T" shaped dock and two 3' X 15' finger piers attached to the "L" shaped dock. The applicant would install 42 mooring pilings in the bottom of Gasparilla Sound for the mooring of boats using the docks. Thus, the applicant proposes the addition of approximately 25 boat slips with the proposed docks, all of which will be located within Gasparilla Sound, in the Charlotte Harbor Aquatic Preserve, an Outstanding Florida Water (OFW). This is a Class II water body pursuant to Chapter 17-3, Florida Administrative Code, and has also been designated an outstanding Florida water, pursuant to Rule 17-3.041, Florida Administrative Code. The docking facility will be located in an area vegetated by sea grass, including turtle grass and associated algae. The access ramp for the "T" dock would be through a mangrove fringe including red, white and black mangroves. The Department's appraisal recommended denial of the application unless certain modifications to the "T" shaped dock are accomplished, including omitting the "T" shaped docking structure or relocating it to an area without grass beds; that the pilings should be driven into place rather than placed in augured holes; that turbidity screens should be installed and staked around the proposed piling site and that no boats over 25 feet in length or equipped with heads or toilets should be allowed to moor at the docking facility, nor should boats be permitted with people living aboard them. On September 5, 1985, the Respondent issued its Intent to Deny indicating that the project was expected to violate water quality standards and that the construction of the dock and the presence of the moored boats attendant to use of the dock would lower existing water quality in terms of turbidity, biological integrity, bacteriological quality, especially as to fecal coliform and total coliform bacteria and based upon the DER's position that the "T" shaped dock would not clearly be in the public interest in several respects. The Department has no objection and proposes to issue a permit for construction of the smaller, "L" shaped dock. In response to the Intent to Deny, the Petitioner resurveyed the seagrasses in the area and located a site where the water depths sloped to deeper water and seagrasses were sparser. It modified its application, moving the waterward extension of the dock over the deeper water in the less dense seagrasses, but could not move the dock to a location to avoid seagrass since to do so would not allow maneuvering room for larger boats utilizing the existing dock. The applicant agreed to the other suggestions of modification by the Respondent. Thus, the applicant subsequently modified the application to include "bow-in" mooring of boats so as to place boat propellors over the deepest possible waters at the mooring site, as well as raising the central portion of the access ramp leading waterward from the shore, to provide for greater light penetration and less shading of seagrasses, as well as narrowing the dock to five feet in width where it passes through the mangrove fringe, so as to limit alteration of the mangroves at the site to only three trees. The Department continues to take the position that the permit should be denied, however, on the basis that the construction of the dock and the presence of the boats attendant to the dock will lower existing water quality in terms of the above particulars and based upon the DER's evaluation that the "T" shaped dock will not clearly be in the public interest. AMBIENT WATER QUALITY The Petitioner tendered C. W. Sheffield, professional engineer, and Dr. Martin Roessler as experts in the field of water quality and they were accepted without objection. The respondent tendered the expert testimony of Mr. Doug Frye and William Porter, respectively a dredge and fill specialist and supervisor and an environmental specialist with the Shellfish Monitoring Program for the Department of Natural Resources, who were accepted as expert witnesses in the areas of water quality and, with regard to Mr. Porter, the impacts of water quality on shellfish. It was thus established that the ambient water quality in the cove which contains the present marina and where the proposed docking facilities would be is generally good. The water meets all relevant State regulatory standards with the exception of fecal coliform and total coliform bacteriological standards for Class II waters. In that regard, repetitive samples have shown violations of the fecal coliform and total coliform bacteriological standards for Class II waters on a number of occasions. The data relied upon concerning fecal coliform organism levels at the project site was collected and analyzed over approximately a one year period during which time the samples were shown to contain fecal coliform and total coliform bacteria in violative concentrations a number of times. Marinas are known discharge sources for fecal coliform organisms. This is especially true of moored boats in marinas which often have toilets or heads which are illegally flushed into the State waters within the marina. The presence of moored boats with heads are known discharge sources of fecal coliform organisms and the boats utilizing the present marina and the proposed project do, and likely will, have toilets on board, which can be improperly discharged into the waters of the marina. This marina has been established to be a source of discharge of fecal coliform organisms in violation of the relevant standard for Class II waters of the State. There presently exists relatively high levels of fecal coliform organisms ranging up to 50 organisms per 100 milliliters of water in the area of the existing marina. This level of concentration exceeds the regulatory standard for fecal coliform bacteria in the Class II water quality rules. Although Mr. Porter discussed the possibility that high levels of coliform bacteria could be caused by birds or animals depositing fecal material in the water, he established that the likely source of elevated levels of this bacteria was improper operation of heads aboard boats, as pointed out by the fact that samples taken in other areas of the Gasparilla Sound away from marina sites do not exhibit the high coliform levels found on repeated occasions at the subject site. Thus, it has been established that the ambient water quality is within State standards for all parameters with the exception of fecal and total coliform bacteria for Class II waters. The Petitioner contends that Class III water standards are appropriately applied herein inasmuch as the Department placed the Class III standards rather than the Class II standards at issue in its Intent to Deny, albeit mistakenly. There is no question, however, that there are Class II waters of the State involved at this site and the subject area is within the aquatic preserve and outstanding Florida waters. The Petitioner is charged with knowledge of this inasmuch as the aquatic preserve boundaries are delimited in the Department's above-cited, published rule. In preparing and processing its application and electing to proceed with this project, the Petitioner is charged with knowledge that these are Class II waters and that the water quality criteria and considerations applicable to Class II outstanding Florida waters are the appropriate parameters with which it must comply. In any event, this is a de novo proceeding and the Department's initial position with regard to this application is not binding in favor of or to the prejudice of any party to the Section 120.57(1), Florida Statutes proceeding. IMPACT ON BENTHIC COMMUNITY ·9. There is a moderate stand of seagrass at the proposed site of the "T" portion of the dock or waterward end of the dock, with dense seagrass beds existing toward the shore, over which the narrower walkway portion of the dock will traverse. Seagrass beds are an especially productive marine community which contribute greatly to the biological diversity in surrounding waters because of their important function in the marine food chain. That function is involved with the seagrasses production of detrital matter consisting of seeds and vegetative material which marine organisms feed upon and upon which organisms larger fish, including commercial and sport fish species, feed upon. Potential adverse impacts caused by a project of this type on the Benthic Community at the project site and especially the seagrass beds involve the potential shading of seagrasses caused by the location of the dock over them, as well as the mooring of boats over them which shading retards or eliminates photosynthesis, which ultimately can kill the seagrass and thus reduce marine productivity in the area. The concentration of boats at such a mooring site as the end of this "T" dock will concentrate the effects of prop scouring, washing and prop dredging, which will have a destructive effect on seagrasses as well as the settling out of sediment from propellor wash or disturbance of the bottom on the seagrasses which can ultimately smother them as well as other marine life forms. In discussing these considerations, it should be pointed out that the "T" portion of the dock would be oriented in a general north-south direction which causes the shadow of the dock to move rapidly as the sun passes overhead in a general east to west direction. This would tend to minimize the effect of shading on the seagrass of the dock itself, particularly with regard to the approach ramp portion of the dock which is relatively narrow. That portion of the dock extending toward the shore runs in an east to west direction and would not exhibit the same rapidly moving shadow, but the central portion of the approach walkway has been elevated to such an extent that light reaching under the dock from both sides will be sufficient to allow photosynthesis of the seagrasses under the dock, although not for as long a period of the day nor at the same rate as would be the case if the dock were not present. The Petitioner asserts that its voluntary relocation of the "T" shaped portion of the dock from an area of dense sea grass to a moderately populated sea grass bed plus the proposed bow-in mooring of boats so as to alleviate propellor damage to the seagrass, together with its view concerning the prevailing water depth at the end of the dock, will serve to prevent damage to the seagrass at the end of the "T" dock where the boats will be moored. It has been shown, however, that the mooring of boats whether bow-in or otherwise will still create a significant amount of shading of the bottom which, together with the shading caused by the "T" dock as well as the associated finger piers will retard or prevent photosynthesis to some extent, especially where boats are moored for days at a time without moving. This will significantly reduce the marine productivity attributable to the seagrass by retarding its natural function or, in some cases, killing it with the resultant loss of the detrital production as well as carbon production, the former being crucial to the proper functioning of the marine food chain in the area. If the seagrass is damaged or extinguished by the shading effect, prop scouring and washing, and/or settlement of turbidity on the seagrass, or a combination of these factors, not only will its productivity be lost, but the biological diversity of marine life in the area will be reduced as it relates to those vertebrate and invertebrate marine animals which depend on seagrass as a food source either directly or indirectly. Dr. Roessler, for the Petitioner, opined that the attached biological communities or "fouling" organisms such as barnacles which would form on the dock pilings, if they were installed, would provide habitat for marine life and invertebrates and thus enhance the biological diversity of the area. These fouling organisms which attach to pilings, however, represent a very narrow portion of the potential marine biological diversity of life forms in an area such as this. Their advent on the pilings, should the pilings be installed, would not mitigate for the loss of important marine habitat and resultant species diversity that elimination of this portion of the seagrass beds would pose. Thus, reasonable assurances have not been established that significant adverse impact to the Benthic Community in the form of damage or elimination of the seagrass beds and their dependent biota will not occur due to shading and propellor scouring, dredging and washing occasioned by the installation of the docking facility. Respondent's expert witnesses Sheftal, Barth, and Dentzau uniformly expressed a concern for propellor scarring, dredging and prop washing of the seagrass beds caused by an improper operation of boats in the project area where water is too shallow over the grass beds to protect them from the resultant propellor damage. In this regard, the Petitioner's own experiments with actual boats indicated that approximately one to 1 1/2 feet of water will remain between the bottom of the sound and the boat propellors at the end of the "T" dock for the general type and size of boats which will use the dock, even assuming that the boats are moored bow inward, thus taking maximum advantage of the deepest water possible under the propellors when a boat engine is started. Respondent's witness Dentzau performed a test with a 21 foot boat with an approximately 100 horsepower outboard engine running it in both forward and reverse at the "T" end of the dock. He was able to readily generate a "plume" of turbidity consisting of sand and other bottom material suspended in the water by the scouring action of the propellor. Although it was demonstrated for water quality parameter considerations that this turbidity plume did not violate the water quality standards for turbidity, it obviously shows that over time the turbidity suspended by boat propellors will settle on the seagrasses and other bottom dwelling biota to their detriment and, more immediately important, demonstrates that prop washing and scouring will occur by boats even if moored bow-in at the presently proposed site of the "T" shaped portion of the dock. The Petitioner proposes by the configuration of its "L" shaped dock in conjunction with the IT" shaped dock, as well as with buoy lines, to keep boat traffic away from the dense grass beds surrounding the proposed dock site and over which the walkway will extend. The Petitioner will mark the entrance channel to the marina itself to keep boats from straying over adjacent grass beds. It has not been demonstrated, however, what steps can be taken to effectively prevent boats from approaching the side of the proposed dock around the ends of the buoy lines and over the dense grass beds toward prohibitively shallow water where prop scouring and scarring will occur. Further, although the Petitioner will mark the entrance channel to the marina itself to keep boats from straying over adjacent dense grass beds, the likelihood of propellor damage to the grass beds in the vicinity of the end of the "T" dock has been exacerbated by the concentration of boat traffic which will result by installation of that dock, over waters at the mooring site which are of insufficient depth to protect the grass bed at that location from scouring and washing from boat propellors. In view of these reasons, significant adverse impacts to the Benthic Communities and especially to the grass beds themselves will result by installation of the docking facility at the site proposed, primarily because of insufficient water depth for safe operation of boats in relation to the well-being of the grass beds in the vicinity of the end of the dock and because of the shading which will result by installation of the "T" shaped portion of the dock in conjunction with the boats to be moored to it and the finger piers between the boat slips attached to it. WATER QUALITY The Respondent, through its water quality expert witness, Doug Frye, expressed the concern that the proposed project would violate Rule 17-3.051, Florida Administrative Code, which requires that the State's waters be free from pollutants above a certain level measured by various accepted and codified scientific methods of measurement. In this regard, the primary concern of the Department is bacteriological quality as well as turbidity resulting from boat operation. The turbidity standards contained in the above Rule provides that State waters not exceed 29 nephelometric turbidity units above the natural background level. The Respondent contends that this level will be exceeded as a result of operation of boats in the vicinity of the dock. The Petitioner, however, presented a soils analysis and silt settling study which showed that bottom materials in the area involved consist of sand, with some finely pulverized shell and that this material settles very rapidly after being disturbed with little silt remaining in suspension a significant period of time after the disturbance. This is primarily because the level of organics in the bottom substrate is very low at this site. In this connection, the Petitioner's expert witness, Mr. Sheffield, anchored a 16 foot boat with a 40 horsepower outboard motor in the docking area of the proposed project. He operated the boat at 1,000 RPM for an extended period of time while measuring the resultant turbidity. The results of his measurements showed turbidity to be in the range of 5-11 NTUs. The Respondent's witnesses, however, operated a larger 21 foot boat at the location of the "T" shaped portion of the dock maneuvering it back and forth with a fairly large outboard motor in the 100 horsepower class, which might be presumed to be typical of the boats which will be using the proposed facility. The maneuvering of the boat with the larger engine in this shallow water created a clearly visible plume of turbidity shown by photographs introduced into evidence by the Respondent. In fact, however, although the turbidity plume was clearly visible, the Respondent's own direct measurement of turbidity taken from within the plume immediately after it was generated was 23.8 NTUs, still below the State standards for violations as to turbidity. The existing marina facility has a fuel dock and has adopted a fuel spill contingency plan. There will be no fueling of boats nor fuel kept at the proposed docks. Nevertheless, marinas were established to be a known source of discharge of oils and greases and the presence of more boats utilizing all the dock facilities, especially during fueling and maintenance procedures, will result in additional oils and greases being deposited in the water. Even if there is no fueling facility planned for the proposed docks, the additional boats represented by the 25 additional slips sought to be approved will have to be fueled and likely at the existing facility. This will heighten the risk of fuel, oil and grease spills. In this regard, it must be remembered that the present marina and the proposed docking facilities are in outstanding Florida waters in which no degradation of ambient water quality is permitted. In this context then, the Petitioner/Applicant has, not provided reasonable assurances that pollution levels for oils and greases will not increase as a result of the potential addition of 25 boats to this marina facility. A substantial issue has been raised in this proceeding concerning water quality as it relates to the bacteriological standard. It has been established that this marina is presently a source of discharge of fecal coliform organisms which frequently are present in sufficient concentrations so as to violate the standard for that organism for Class II waters. Fecal coliform bacteria are accumulated in the bodies of shellfish. The shellfish themselves are not harmed, but contaminated shellfish can accumulate concentrations of as much as 100 times the ambient fecal coliform bacterial levels present in the waters they inhabit. Fecal coliform bacteria can cause extreme illness in human beings, sometimes even paralysis and death. Fecal coliform bacteria in State waters results from the deposition therein of human or animal waste. The Petitioner maintains a sewage pumpout station located at its fuel dock with a direct connection to its sanitary upland sewer system, as well as a portable sewage pump that can be moved to each boat slip for pumping out of toilets or "heads" on boats. Upland fish cleaning stations will additionally be provided with the proposed docks so as to prevent refuse from fish cleaning activities being deposited into the waters of the cove. The fact remains, however, that there presently exist high levels of fecal coliform organisms in the waters of the cove at the marina site, in the above noted violative concentrations on repetitive occasions. The presence of boats moored in the marina with "heads" aboard are a known discharge source of fecal coliform organisms. The Petitioner proposes to restrict boats using the facility to those boats without marine heads aboard or requiring those with heads to keep them locked or otherwise not discharge them into the waters of the marina. If boats utilizing the marina have toilets aboard, however, there is a substantial likelihood that at some point those toilets will be discharged into the waters of the cove before any of the Petitioner's monitoring personnel are aware of it. The problem is thus one of enforcement. In this regard, it is established that even with the sewage pumpout station and the portable sewage pumpout device, that there are a number of "live-aboard" boats with marine heads in the marina at the present time and customarily. This has caused the above found violations of fecal coliform, Class II water standards. Although the Petitioner proposes to restrict boats at the proposed docking facility to those less than 25 feet in length and to establish a monitoring program by the marina management personnel to assure that the boats with heads only contain heads approved by Coast Guard regulation, reasonable assurances have still not been established that the enforcement plan proposed can be effective in ensuring that no marine heads or other sources of coliform bacteria will be discharged into the waters of the cove at the project site. The plan proposed by the Petitioner simply did not ensure that boats having marine heads will not use the marina and that those persons using boats so equipped will not, on some occasions, discharge the heads into the waters of the marina at the project site nor that spills will not result in the sewage pumping-out process. The Respondent's expert witness, Mr. Porter, confirmed that most fishing boats of the open "center console" variety of 25 feet length or less do not contain marine heads, nevertheless, he established that in his experience monitoring marinas of this sort, the restrictions against marine heads of the non-approved variety and the attempted restriction against boats discharging the contents of their heads into the waters of the marina cannot be effectively enforced nor was it established that fishing boats without marine heads will be the only type of boat to use the proposed docking facilities. Accordingly, the waters of the cove at the marina site and project site are in frequent violation of the fecal coliform and total coliform parameter for Class II waters and reasonable assurances have not been provided that the fecal coliform bacterial levels will not increase as a result of the installation and operation of the proposed facility with its attendant boats. Because of the likelihood of shellfish contamination by fecal coliform bacterial levels which will likely increase if the proposed project is constructed and operated, together with the loss of marine habitat and productivity posed by the harm likely to result to the seagrass beds in the vicinity of the proposed facility due to attendant boat operation, it has been shown that the water quality parameter for biological integrity in these Outstanding Florida Waters will likely be degraded. The "Diversity Index" of marine microinvertebrates in the area of the affected seagrass beds will likely be reduced below 75 percent of background levels. Therefore, in the context discussed above, the proposed construction and operation of the 25-slip marina facility with the "T" dock will lower ambient water quality in these outstanding Florida waters and will result in violations of State water quality standards for Class II waters in the above particulars. SHELLFISH HARVESTING Mr. William Porter of the Department of Natural Resources Bureau of Shellfish Sanitation established that the cove where the project would be located is closed to the taking of shellfish as a result of the contamination or potential for contamination of shellfish by coliform bacteria contained in fecal material. His Department's water quality sampling confirmed the elevated levels of fecal coliform bacteria in the cove on repetitive occasions. This elevated level of coliform organisms was shown to result from improper operation of marine toilets upon vessels using the marina at the present time. Because of the potential for contamination from vessels discharging fecal material, Mr. Porter established that the Department would likely close an area 50 percent larger than the present shellfish harvest closure area as a result of a 50 percent increase in the number of boats capable of using the marina if the proposed project is built. Mr. Porter acknowledges that if it could be assured that boats using the marina did not contain heads, the increased area of closure might be lessened after this project were built. He also established as pointed out above that such restrictions on boats containing heads from using the proposed boat slip is very difficult to enforce. Even with the present central sewage pumpout facilities and portable pumpout equipment at the existing marina, the marina still has failed to comply with fecal and total coliform standards for Class II waters on a repetitive basis. The management of the present marina has allowed live-aboard boats at the marina even though it has posted warning signs against boat owners discharging toilets in the cove waters. Mr. Porter also acknowledged that the Boca Grande North Marina, owned by Gasparilla Pass, Inc., was recently permitted by the DER and constructed and has not yet resulted in the Department's closing an additional area to the taking of shellfish. The area the marina is situated in, however, is only "conditionally approved" for the taking of shellfish, meaning that it is subject to closer monitoring by the DNR with a view toward the possible necessity of closing waters in the area of that marina. It was not established, however, how the fecal coliform or total coliform levels in the waters adjacent to that marina compare to the existing marina or the site of the proposed docking facilities at the existing marina, nor what conditions might prevail which would render that other marina a comparable site to -be used as a relevant demonstration of what conditions might be expected at the present marina if the proposed project were built and operated. Thus it has been shown that even though the Petitioner proposes limiting the size of boats at the proposed facility and closely inspecting and regulating any marine heads on boats using the facility to make sure they comply with Coast Guard regulations, it has not been demonstrated that the additional deposition of fecal coliform bacteria in the waters often the cove will be adequately prevented by the proposed enforcement measures. It is thus reasonably likely that the construction of the proposed project will lead to the closing of an additional area of water which is presently approved for shellfish harvesting. The closure of shellfish harvesting in waters is contrary to the public interest in terms of recreational values, fishing and marine productivity and others of the seven public interest criteria quoted below. Further, the contamination of shellfish, which can cause severe illness or even death in human beings, is clearly contrary to the public interest and there is a substantial likelihood that shellfish contamination is already occurring in the area due to the characteristic of shellfish by which they accumulate or store fecal coliform organisms to reach injurious levels for human consumption even though the shellfish themselves appear to be healthy. The area of the proposed project is extensively used for commercial and recreational shellfish harvesting at the present time, outside the immediate closed waters of the marina within the cove. PUBLIC INTEREST Section 403.918(2) (a) (1-7) requires that the Petitioner provide reasonable assurances that the proposed project will be clearly in the public interest. The public interest considerations of those seven criteria concern whether the project will adversely affect public health, safety or welfare or property of others: whether it will adversely affect conservation of fish and wildlife or their habitats; whether it will adversely affect the fishing or recreational values or marine productivity in the project vicinity; whether it will be of a temporary or permanent nature; and the effect on the current condition and relative value of functions reformed by areas affected by the project. Although Petitioner's witness, Dr. Roessler, related that the attached fouling communities, such as barnacles, which would form on the proposed docks and pilings would increase the diversity of marine habitat available, that will not offset the loss of marine habitat occasioned by the increasingly detrimental effect imposed by the project and the operation of it on the seagrass beds, in the manner discussed above. The fouling communities expected by Dr. Roessler to occur on the pilings to be installed, will not provide, nor replace the value of, the detritus (seeds and leaves) produced by the seagrass which would be lost, which is an important food source for marine organisms in the upper portion of the food chain in the area, some of which organisms include fish and have a high recreational value and commercial value. The importance of detrital production by the seagrass beds outweigh the value of the addition of the fouling communities on the pilings. In fact, the total diversity of marine species actually might decline even though the fouling organisms would be added with the installation of the pilings, once the harmful effects on the seagrass beds begin to occur after installation and operation of the proposed facility and over the life of the marina. Thus, in this regard, the project is contrary to the public interest and certainly not clearly in the public interest. Additionally, there is a substantial likelihood that shellfish may be contaminated which, in turn, will have an adverse effect on the public health, safety and welfare. The harvesting of shellfish has a substantial recreational and commercial value and is an important aspect of the marine productivity in the vicinity of the project. The heightened coliform bacteria production caused by the resultant expansion of the marina will adversely affect fishing and recreational values and marine productivity and will degrade the current condition and relative values of the functions performed by the marine habitat in the vicinity of the proposed dock. Finally, there is no question that the project will be of a permanent nature. The various detrimental effects on the public interest consideration found herein are rendered more critical by the fact that there is no truly redeeming public purpose or use for this project. This will be essentially a private docking facility designed to serve the residents of the applicant's attendant real estate development. The upland development is a condominium development and the slips will be owned by the condominium owners and not open to the general public, although the Petitioner did make vague reference to an idea that some slips might be rented to members of the public. This was not established to be the case and, in any event, the primary purpose of the boat slips is to enhance the desirability of the upland development. Although the Petitioner emphasizes that the advent of the additional slips might help attract as much as $1,000,000 additional revenue to the Boca Grande area by assisting the applicant in hosting the Annual Tarpon Release Fishing Tournament, it is also true that any development in a coastal area will likely represent some economic benefit to that area, but there is also a substantial economic and recreational benefit to maintaining the outstanding Florida waters involved in an undegraded condition and maintaining the present Class II, approved shellfish harvesting area unimpaired. Thus, although the proposed docks might be used for sponsorship of the subject fishing tournament and it can be said that that would enhance fishing and recreational value to some extent, it was not established that the tournament will not occur and that the extra revenue and enhancement of fishing and recreational value it will generate will not occur in the Boca Grande area anyway. The potential detrimental effects of the proposed project, delineated above, will also decrease fishing and recreational value over many years and for the life of this project in terms of harm to the marine habitat occasioned by the constant deposition of oils, greases and fuel and coliform bacteria in the Class II waters involved, as well as the other detrimental aspects of the project discussed above. It has not been established that the economic benefits of the fishing tournament and the addition of the boat slips will not occur but for the installation of this proposed docking facility. Although it may help relieve a shortage of marina slips in the area, it was not shown that this is the only alternative to relief of that shortage. ALTERATION OF MANGROVES The original site for the access ramp or walkway to the "T" shaped portion of the dock was selected through an on site inspection conducted in part by Respondent's witness, Andrew Barth. The mangrove area is less dense at the site of the walkway's penetration of the mangrove belt than surrounding mangrove areas. Petitioner's witness, Dr. Roessler, has participated in many studies involving mangroves in South Florida. He identified each tree within the proposed dock pathway. Through narrowing of the dock walkway to five feet and the relocation agreed upon by the Petitioner and Mr. Barth, it has been established that only three mangrove trees will be removed by the construction of the dock. Thus, there will be no substantial alteration or degradation of the mangrove fringe area at the project site. DOCK CONSTRUCTION Mr. C. W. Sheffield was accepted as an expert witness in the field of marine engineering. He established that the pilings will be installed using a 6 to 8 inch chisel point driven into the bottom of the sound with an air hammer. There will be no augering or other means of excavation used which would generate a substantial amount of turbidity. The air hammer will result in compaction of sediments by forces radiating out from the piling as it is driven, with the counteracting sheer force caused by the piling installation causing a slight bulging in the bottom around each piling, but nothing more. There will be no significant movement of sediment in the water column. The construction of the dock will take place moving from the land waterward, utilizing equipment mounted on the dock. Thus, construction barges will not be required to come into the shallow grass bed area with the potential for its damage. Small barges would be used in the deeper waterward portions of the project to install the mooring pilings off-shore from the end of the "T" dock. Turbidity curtains will be used during all construction, surrounding all phases of the construction work. In Mr. Sheffield's experience, such measures have resulted in no violation of the State turbidity standards at other similar projects, and are not likely to with this one. CUMULATIVE IMPACT A number of permits have been issued by the Department for docking facilities to the north of this proposal and other facilities are already in existence. Dr. Roessler opined that the geographic location of these, as well as that of this project, in light of the numerous inlets and high degree of tidal flushing and exchange through the inlets, will not result in any adverse cumulative impact occasioned by the addition of the proposed dock with 25 slips to those already existing in the Sound. It is noteworthy that, with regard to the potential this project poses for damage to the seagrass beds and for heightened production of fecal coliform bacteria, with the environmental damage attendant thereto, no proof was offered by either party concerning those considerations or effects to the extent that they might or might not exist at other marinas or docking facilities in the Gasparilla Sound area. There has been no proof to establish any cumulative impact.
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the testimony and evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is, therefore RECOMMENDED that a Final Order be entered denying the subject permit application, except for that portion seeking authorization for the "L" shaped dock and six boat slips attendant thereto, which should be granted with the agreed-upon conditions and restrictions contained in the above Findings of Fact.

The Issue The issue is whether reasonable assurance has been provided by Sarasota County (County) for the issuance of Environmental Resource Permit (ERP) No. 44040881.000 authorizing the proposed alteration of a drainage ditch in the City of Sarasota (City), and whether Petitioner, SRQUS, LLC, was entitled to receive notice of the application pursuant to Florida Administrative Code Rule 40D-1.603(9)(a) and (b).
Findings Of Fact Parties Petitioner is a Florida limited liability corporation established in 2010 whose only members are Erika and Achim Ginsberg-Klemmt. In 2010, Petitioner purchased parcel 2009-16- 0015 in a tax deed sale. The parcel consists primarily of the submerged lands within the marina basin adjacent to the project area. Petitioner contends that the tax deed accords it ownership of the western most 130 feet of the existing ditch and that the County is not authorized to do work on that property. The City and County dispute this claim and it is now being litigated in circuit court. The City claims ownership or control of all of the project area to be addressed under the permit. The City authorized the County to apply for and construct the improvements authorized by the permit pursuant to an interlocal agreement with the County for consolidation of stormwater management responsibilities. The District is the agency charged with the responsibility of controlling water resources within its geographic boundaries and to administer and enforce chapter 373 and the rules promulgated in rule division 40D. The County submitted the application pursuant to an interlocal agreement with the City and will construct, operate, and maintain the project if the permit is issued. The Project U.S. Highway 41, also known as Tamiami Trail, travels through downtown Sarasota. During rainy months, between Fruitville Road and Second Street, U.S. Highway 41 experiences frequent roadway flooding. At the area where U.S. Highway 41 floods and between the Quay development to the north and the Ritz-Carlton Hotel to the south, is a stormwater ditch that drains west into a marina basin or bayou adjoining Sarasota Bay. However, it does not directly discharge into Sarasota Bay. The ditch is an upland cut drainage ditch approximately 650 feet in length and has been in existence for decades. The ditch is covered under a National Pollutant Discharge Elimination System (NPDES) Municipal Separate Stormwater Sewer System (MS4) permit issued to the County for the surrounding communities. Contaminants in the stormwater system are addressed under this permit. The ditch provides the only outfall for an approximately 46-acre heavily urbanized drainage basin for which stormwater is collected through the stormwater system. The stormwater is discharged into the drainage ditch through a double concrete box culvert under U.S. Highway 41 and is ultimately conveyed to a marina basin adjoining Sarasota Bay. The ditch is located in what was originally platted as the right-of-way for Eighth Street (now known as Second Street) on the Central Broadway subdivision plat within the City. Pursuant to an earlier exemption determination by the District, in 2004 the County conducted maintenance dredging on the easterly portion of the drainage ditch in an effort to remove the sediments and vegetation that had built up in the ditch over the years and reduced its flow. Since that time, the ditch has again filled in as a result of the significant amounts of sedimentation from stormwater flows entering and settling in the ditch and significant amounts of vegetation. Also, flooding on U.S. Highway 41 has become more frequent. In its current condition, the ditch is approximately eight to 12 feet wide and eight to 12 inches deep, is poorly drained due to the sedimentation and heavily overgrown mangroves and nuisance vegetation, and is tidally influenced. Accumulated sediments in the ditch are approximately four feet thick at the eastern end and become thinner at the western end of the ditch. In August 2009, staff from the City, County, District, and Florida Department of Transportation met at the site of the ditch to conduct a pre-application meeting and discuss possible ways of addressing flooding problems at this location. Aside from the ditch improvements being proposed by the County, the only other remedy is to pipe the ditch, which is cost-prohibitive and would defeat the County's goal of keeping as much desirable vegetation in place as possible. To address flooding and maintenance concerns, on September 8, 2011, the County submitted an ERP application to the District to seek authorization to dredge and undertake ditch improvements. The application identifies the ditch as being within City right-of-way. Included with the application was a letter from the City authorizing the County to apply for the ERP on behalf of the City pursuant to their interlocal stormwater agreement. At the time the application was filed, the County Property Appraiser's Office Geographic Information Systems tax parcel map showed the ditch and dredge area as being within the City right-of-way. The proposed project consists of reconstruction of the ditch with a defined channel to be lined with rip rap and geotextile fabric and the addition of two sediment sump boxes. Some of the mangroves and nuisance vegetation will be removed as necessary to construct the ditch improvements. Mangroves will be preserved where not impacted by construction. The Property Dispute Petitioner claims ownership of the western 130 feet of the right-of-way in which the ditch is located. As noted above, at the time the permit application was submitted, official property records showed the existing ditch as located within City right-of-way. Therefore, the County and District had no reason to doubt City ownership or control of the ditch area. A recently filed circuit court action seeks to determine ownership of a portion of the right-of-way in which the ditch is located. The circuit court has exclusive jurisdiction over all actions involving the titles and boundaries or right of possession of real property. District rules permit applicants to demonstrate sufficient ownership or legal control of the proposed project area in order to conduct the activities to be permitted. An applicant with eminent domain authority that does not have ownership or control for all property necessary for the proposed project may rely on its eminent domain authority to demonstrate sufficient ownership or legal control of the property necessary to construct the project. The permit will be conditioned to prohibit construction until all ownership or legal control of the property necessary to construct the project is acquired by the permittee. See Fla. Admin. Code R. 40D-4.301(1)(j); BOR § 2.0. The proposed permit contains Specific Condition No. 8 which enforces this requirement. Reasonable assurance of sufficient ownership or legal control of the project area is provided by virtue of the City's and County's eminent domain authority and the fact that the proposed permit prohibits construction until the permittee acquires all necessary ownership or other legal control of the property necessary to construct the project. Notice Requirements Petitioner contends the permit should be denied because it did not receive notice of the application pursuant to rule 40D-1.603(9). That rule provides that when the applicant is an entity with the power of eminent domain that does not have current ownership or control of the entire project area as described in the application, the applicant shall provide the property owner(s) identified in the application with so-called eminent domain noticing, which consists of (a) written notice of District receipt of the application, and (b) written notice of agency action on the application. Persons entitled to eminent domain noticing are owners of property located within the proposed project area as identified in the county property appraiser's records within 30 days prior to the filing of the application. The purpose of the District's eminent domain noticing provision is to provide notice and an opportunity to be heard to owners of property subject to being condemned or otherwise acquired by the applicant for part of the project area. As originally submitted, the application proposed some activities extending approximately ten feet into the marina basin and beyond the claimed City right-of-way. The permit application did not indicate City ownership or control of submerged lands within the marina basin. Consequently, in its request for additional information (RAI), the District advised that pursuant to rule 40D-1.603(9)(a) and (b), eminent domain notices to affected landowners would be required for any proposed easements over offsite property. As part of the application process, a seagrass study was prepared which showed seagrasses and oyster beds growing in the marina basin just beyond the end of the ditch, where some construction activity was proposed. Because seagrasses were observed growing at the end of the ditch, the County responded to the RAI by scaling back the project to confine activities to the City's right-of-way. With the change in project area, offsite easements were no longer necessary for the project. Thus, the project no longer required eminent domain noticing pursuant to rule 40D-1.603(9). The County and District acknowledge that Petitioner did not receive eminent domain notices. Although not provided notice, Petitioner nevertheless became aware of the permit application during the course of its own application process with the Department of Environmental Protection (DEP) for an ERP to construct a 4,760-square foot, ten-slip docking facility on its adjacent submerged lands in the marina basin. The lack of notice has not prevented Petitioner from challenging the project or has otherwise prejudiced it. Having received actual notice of the permit, Petitioner filed a timely objection and request for hearing in this matter. Petitioner contends that while it does not oppose the ditch dredging, it would have wanted an opportunity to suggest a re-design of the ditch to include a dingy dock and kayak launching facility. Although it has known of the project since at least May 21, 2012, when it filed its first petition, and probably several months earlier, Petitioner has not provided the County or District with any alternative designs to maximize the potential for recreational use of the drainage canal. There is no requirement for ERP applicants to provide alternative designs to maximize potential public recreational uses. Requiring the County to do so would impose requirements that go beyond the conditions for permit issuance. ERP Permitting Criteria To obtain an ERP, a permit applicant must provide reasonable assurance that the proposed activities will not cause adverse impacts to water quality, water quantity, and other environmental resources. For activities proposed in, on, or over wetlands and other surface waters, reasonable assurance must also be provided that such activities are not contrary to the public interest and do not cause unacceptable cumulative impacts upon wetlands and other surface waters. The conditions for issuance of an ERP are set forth in rules 40D-4.301 and 40D-4.302. The standards and criteria in the BOR are used to determine whether an applicant has met the conditions for issuance in those two rules. The parties have stipulated that the project either complies with the following conditions for issuance or that they are not applicable: 40D-4.301(1)(b), (c), (g), (h), (j), and (k) and 40D-4.302(1)(a)6. Also, rule 40D-4.302(1)(c) and (d), which concerns projects located in, adjacent to, or in close proximity to certain shellfish harvesting waters or which involve vertical seawalls, is not applicable to this matter. Based on the parties' Stipulation, at issue is whether reasonable assurance has been provided that the proposed activities will not cause adverse water quantity impacts to receiving waters and adjacent lands (40D-4.301(1)(a)); will not adversely impact the value of functions provided to fish and wildlife by wetlands and other surface waters (40D-4.301(1)(d)); will not adversely affect the quality of receiving waters such that applicable state water quality standards will be violated (40D-4.301(1)(e)); and will not cause adverse secondary impacts to the water resources (40D-4.301(1)(f)). Petitioner also contends that the County has failed to give reasonable assurance that the project is not contrary to the public interest and that it will not cause unacceptable cumulative impacts, as required by rule 40D-4.302(1)(a) and (b). Water Quantity Impacts Rule 40D-4.301(1)(a) requires reasonable assurance be provided that the project will not cause adverse water quantity impacts to receiving waters and adjacent lands. Existing and post-construction flows were modeled by the County using the accepted Inter-Connected Pond Routing model. Drainage calculations demonstrate that for the 25-year storm, the flood stage will be reduced by 1.94 feet, and for the 100-year storm event, by 1.75 feet, which will provide flood relief. Modeling results demonstrate a reduction in flood stages not just for U.S. Highway 41 but for other adjoining properties. The evidence establishes that while the project is not designed to eliminate all potential flooding, flooding during normal events will be reduced. Specifically, no adverse water quantity impacts were demonstrated with respect to Petitioner's adjacent submerged lands. Improvements proposed to the ditch will increase its storage capacity and allow water to flow more efficiently. By increasing the storage and hydraulic efficiency of the ditch without generating any additional runoff volume, the proposed activities will not cause adverse water quantity impacts and will have no adverse water quantity impacts on the receiving waters. Reasonable assurance has been demonstrated that the project will not cause adverse water quantity impacts to receiving waters or adjacent lands and will not cause adverse flooding to on-site or off-site property, including adjacent submerged lands owned by Petitioner. Impact on Value of Functions Rule 40D-4.301(1)(d) requires that reasonable assurance be provided that project activities "will not adversely impact the value of functions provided to fish and wildlife, and listed species including aquatic and wetland dependent species, by wetlands, other surface waters and other water related resources of the District." The existing ditch provides limited ecological functions for fish and wildlife, as it contains significant levels of exotics and nuisance vegetation that provide little in the way of habitat. The removal of the nuisance vegetation, improved water circulation, and decreased sediments will be an improvement. The proposed ditch reconstruction and replanting with other vegetation will provide a more suitable habitat for younger life stages of fish such as sea trout, red fish, and hog chokers, which are species typically found in tidally influenced drainage systems. Overall, the proposed project will result in an improved habitat available for fish and wildlife. The project will retain as many of the existing mangroves as possible, thereby retaining the ecology of the mangrove wetlands. Reasonable assurance has been provided that the project will not adversely impact the value of functions being provided to fish and wildlife and will actually improve the ecological functions provided by the ditch. Quality of Receiving Waters Rule 40D-4.301(1)(e) requires that reasonable assurance be provided that the proposed ditch alterations will not adversely affect the quality of receiving waters such that water quality standards will be violated. The parties have stipulated that the project will not violate water quality standards set forth in rule chapters 62-522 and 62-550. Petitioner contends, however, that reasonable assurance has not been provided concerning possible impacts relating to surface water quality standards in rule chapter 62-302, the anti- degradation provisions of rule chapter 62-4, or the groundwater permitting and monitoring requirements of rule chapter 62-522. No evidence was presented by Petitioner that the activities will adversely affect the groundwater protection provisions of rule chapter 62-522. The proposed ditch alterations do not involve activities relating to these state water quality standards. Under BOR section 3.2.4, reasonable assurance must be provided for the short term and the long term that water quality standards are not violated. As to potential construction or short-term impacts, the proposed construction work involves the removal of sediments accumulated in the ditch, reconstruction of the ditch to be wider and deeper and within a more defined course, the addition of rip rap and geotextile fabric on the ditch bottom, and replanting of the ditch banks with salt- tolerant grasses and other vegetation to provide soil stabilization and erosion control. The proposed permit addresses the potential for turbidity during construction activities to cause short-term water quality violations by authorizing a temporary mixing zone and by requiring the installation of turbidity barriers and ongoing turbidity monitoring during construction. To further minimize the potential for any water quality violation during construction activities, construction methods will include the use of cofferdams or similar techniques to provide a barrier between the open water of the marina basin and the work being constructed within the ditch, which will be undertaken in segments starting at the eastern outfall at U.S. Highway 41. These provisions adequately address the potential for any short- term water quality impacts and are consistent with BOR provisions relating to short-term water quality. As to possible long-term water quality impacts, the evidence establishes that the proposed activities will not add any additional pollutants or new pollutant source to the receiving waters and will not cause or contribute to any violation of water quality standards. To the contrary, by removing existing stormwater sediments, which are known to contain pollutants, controlling sedimentation through collection of sediments in sediment sumps, and armoring the ditch channel to prevent erosion, water quality is expected to improve. The proposed sediment sumps to be added as a best management practice are appropriately sized to handle the approximately 5,600 pounds of sediments that accumulate annually in the ditch, as determined by annual pollutant load calculations provided by the County. The sumps will be located most efficiently at the outfall where the ditch begins. Preventing sediments from entering the receiving waters is one of the best things that can be done to improve water quality in nearby Sarasota Bay. Improvements in water quality are also expected to occur as a result of the addition of rip rap that will dissipate the flow energy, thereby allowing any remaining sediments to settle down, and the geotextile fabric that will keep soil in place and not allow it to float up. The sodding and replanting of the ditch embankments will also prevent side erosion from occurring, which erosion could add sediments in the ditch. Once constructed, the ditch will be regularly maintained by the County, with sediments to be cleaned out of the sump on a quarterly schedule. Any sediments settling on the rip rap and on plant vegetation would be cleaned out as needed, as determined by regular inspections. Petitioner contends that reasonable assurance has not been provided to show that water quality standards in rule chapter 62-302, and the anti-degradation provisions of rule chapter 62-4, will not be violated by the proposed activities. Its expert opined that the impact of the proposed activity on state water quality standards cannot be determined because no sampling of the receiving water was conducted, the permit does not require compliance monitoring, and the existing ditch sediments were not sufficiently analyzed. The evidence establishes that it can be reasonably presumed, without compliance monitoring or sampling, that the water flowing from the 46-acre urbanized watershed served by the ditch contains sediments and other pollutants typically associated with urban runoff. Most of the expected pollutants are contained within, or settle into the sediments that are deposited into, the ditch. By removing sediments through the use of adequately sized sediment sumps, slowing the water down to allow suspended solids to settle out within the ditch, adding geotextile fabric and rip rap covering the ditch bottom, establishing vegetation on the ditch sidebanks to prevent erosion, and implementing periodic maintenance through vacuum removal of collected sediments, the proposed activities will remove pollutants from the water flowing into the ditch and discharging into the marina basin and ultimately entering Sarasota Bay. Thus, it is reasonable to expect without sampling or monitoring that the proposed activities will improve water quality. In addition to identifying the positive benefits of the proposed activities, the evidence established that the proposed activities will not add a pollutant source to the receiving waters. This was not credibly disputed by Petitioner. Because the project does not generate pollutants, the proposed activities will not cause or contribute to a violation of state water quality standards. There is no reason to require pre-construction or baseline sampling to compare with post- construction sampling, as no pollutants will be generated. The removal of sediments and ongoing ditch maintenance will result in an improvement in water quality. Therefore, it can be reasonably assured without requiring sampling or monitoring that the activities will not result in any violations of state water quality standards. Secondary Impacts Rule 40D-4.301(1)(f) and BOR section 3.2.7 require that an applicant provide reasonable assurance that a regulated activity will not cause adverse secondary impacts to the water resource. As originally proposed, the project included activities extending beyond the end of the ditch and into the marina basin, where seagrasses and oyster beds are present. By avoiding impacts to these resources, the project also avoids any secondary impacts to manatees that may frequent Sarasota Bay. Turbidity control measures to be used during construction will also avoid secondary impacts to these resources. Petitioner provided no evidence that secondary impacts would occur as a result of the project. Reasonable assurance has been provided that the proposed activities will not result in any secondary impacts to the water resources. Public Interest Test Rule 40D-4.302(1)(a) requires an applicant to provide reasonable assurance that activities to be located in, on, or over wetlands and other surface waters will not be contrary to the public interest, as determined by balancing certain criteria, or if such activity significantly degrades or is within an Outstanding Florida Water (OFW), that the activity will be clearly in the public interest. The proposed activities are not located within Sarasota Bay, a designated OFW. Petitioner provided no evidence that the proposed activities would significantly degrade that body of water. Therefore, the County need only demonstrate that the proposed activities are not contrary to the public interest. The parties have stipulated that rule 40D- 4.302(1)(a)6., which governs historical and archaeological resources, is not applicable to this matter. The remaining criteria at issue are whether the activity will adversely affect the public health, safety, or welfare or the 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 of marine productivity in the vicinity of the activity; whether the activity will be of a temporary or permanent nature; and the current condition and relative value of functions being performed by areas affected by the proposed activity. The evidence establishes that the project will reduce flooding during normal stages and remove sediments. By reducing the potential for roadway flooding and improving water quality through sediment reduction, the project will have a beneficial impact on public health, safety, and welfare, and will not adversely affect the property of others. Efforts were made to reduce or eliminate impacts to wetlands and other surface waters in the design of the project. Proposed activities will involve the removal of some of the existing mangroves. Based upon an analysis conducted pursuant to the Uniform Mitigation Assessment Manual, the unavoidable impacts to wetlands and other surface waters will result in a functional loss score of 0.08. Unavoidable wetland and other surface water impacts anticipated from the project will be appropriately mitigated through the use of a 0.08 credit from the Curry Creek Regional Offsite Mitigation Area (ROMA). The evidence demonstrates that the project will not adversely affect the value of functions provided by wetlands and other surface waters to conservation of fish and wildlife, including any endangered or threatened species, or their habitats and will actually result in an improvement in wetland and other surface water functions and habitat. The evidence establishes that the proposed activities will not adversely impact navigation or the flow of water and will not cause erosion or shoaling. The ditch reconstruction will prevent the possibility of shoaling at the downstream end of the ditch adjoining Petitioner's submerged lands by increasing the width of the ditch, slowing the water down, removing sedimentation along the ditch bottom, and reducing erosion through the planting of salt-tolerant sod and other vegetation along the ditch side banks. Petitioner presented no contrary evidence. No adverse impacts are expected to occur with respect to fishing or recreational values or marine productivity in the vicinity of the proposed activity. By removing sediments, the project will provide an improvement to fishing and recreational activities in the marina basin and Sarasota Bay. Petitioner raised concerns regarding the amount of floatable material that will be discharged from the ditch as a result of removal of mangroves. As provided in the permit plans, significant portions of the mangroves will remain undisturbed. Under current conditions, the ditch and mangroves do not prevent or trap all trash and floatables entering the ditch. On-site observations of existing conditions confirmed there is not a large amount of trash and floatables currently being retained by existing mangroves. Any temporarily retained floatables within the ditch area ultimately float out to Sarasota Bay with the tide. The evidence establishes that even with the removal of some mangroves, the project is not expected to result in an easier flow or increased amount of floatables entering the marina basin. Finally, because the project activities do not add floatable materials to the ditch, requiring the County to implement design changes to remove floatables would exceed what is necessary to meet the conditions for permit issuance. Petitioner also raised concerns regarding the levels of fecal coliform and the possibility of illicit connections to the stormwater collection outfalls to the ditch. The ditch is part of a MS4 permit that is regulated pursuant to NPDES Permit No. FLS000004 issued to the County. The NPDES permit governs stormwater discharges within the unincorporated portions of the County, the municipalities within the County, and that part of Longboat Key that is in Manatee County. The primary function of the MS4 permit is to address issues of water quality as they relate to stormwater discharges. The MS4 permit requirements would be the appropriate regulatory framework to address elevated fecal coliform, illicit connections, or other water quality concerns in the stormwater emanating from the drainage basin served by the ditch, and not the ERP regulatory program. Having weighed and balanced the six applicable criteria, and based upon the evidence presented, the County has provided reasonable assurance that the proposed activities will not be contrary to the public interest. Cumulative Impacts Rule 40D-4.302(1)(b) requires an applicant to demonstrate that the proposed activities will not cause unacceptable cumulative impacts on wetlands and other surface waters, as further described in BOR sections 3.2.8 through 3.2.8.2. BOR section 3.2.8 provides that if an applicant proposes to mitigate any adverse impacts within the same drainage basin as the impacts, and if the mitigation fully offsets those impacts, then the regulated activity is considered to have no unacceptable cumulative impacts upon wetlands and other surface waters. Mitigation for unavoidable wetland impacts upon wetlands will be provided through the use of the 0.08 credit from the Curry Creek ROMA. The evidence establishes that the proposed mitigation fully offsets the impacts and is within the same drainage basin as the proposed impacts. No adverse cumulative impacts will occur with the project. Petitioner presented no contrary evidence of adverse cumulative impacts. Impaired Receiving Waters Petitioner contends that the project does not comply with the requirements of rule 40D-4.301(2) and related BOR section 3.2.4.5, which are applicable when existing ambient water quality does not meet state water quality standards. Rule 40D-4.301(2) provides that if an applicant is unable to meet water quality standards because existing ambient water quality does not meet standards, the applicant shall meet the requirements of BOR section 3.2.4.5 and related sections cited in that provision. Together, these provisions require that where existing ambient water quality does not meet standards, the applicant must demonstrate that for the parameters that do not meet water quality standards, the proposed activity will not contribute to the existing violation. If it does contribute to the existing violation, mitigation measures will be required that result in a net improvement of the water quality in the receiving waters for the parameter that does not meet standards. The marina basin that is the receiving waters for the ditch has been identified by DEP as impaired due to levels of mercury in fish tissue. The evidence demonstrates that the project will not contribute to this water quality violation. Although not required to implement mitigation measures that will cause a net improvement of the levels of mercury in fish tissue, the evidence establishes that to the extent existing sediments contain mercury deposits, removal of the sediments reduce a source of mercury that can be ingested by fish in the receiving waters. Water Quality Certification Petitioner contends that Specific Condition No. 9 of the proposed permit, which expressly waives certification of compliance with state water quality standards, is contrary to Section 401 of the Clean Water Act, 33 U.S.C. § 1341, and inconsistent with the legislative declaration of policy set forth in section 373.016(3)(f) and (j). As explained by unrefuted testimony of the District, the water quality certification provisions of Section 401 allow states an opportunity to address the water resource impacts of federally issued permits and licenses. Under Section 401, a federal agency cannot issue a permit or license for an activity that may result in a discharge to waters of the United States unless the affected state has granted or waived Section 401 certification. A state may grant, deny, or waive certification. Granting certification allows the federal permit or license to be issued. Denying certification prohibits the federal permit or license from being issued. Waiving certification allows the permit or license to be issued without state comment. Pursuant to rule 40D-4.101(4), an application for an ERP shall also constitute an application for certification of compliance with state water quality standards where necessary pursuant to Section 401. Issuance of the permit constitutes certification of compliance with water quality standards unless the permit is issued pursuant to the net improvement provision of section 373.414(1), or the permit specifically states otherwise. By letter dated February 2, 1998, to the United States Environmental Protection Agency, DEP has delegated to the state's five water management districts the authority to issue, deny, or waive water quality certifications under Section 401. DEP has also established categories of activities for which water quality certification will be considered waived. Under the DEP delegation, water management districts may waive water quality certification for four situations, one of which is when the permit or authorization expressly so provides. This is still current DEP direction. The types of permitting decisions which constitute the granting of water quality certification and the types of activities for which water quality certification could be considered waived are also addressed in the current Operating Agreement between the United States Army Corps of Engineers (USACE), DEP, and the five water management districts. According to both DEP guidance and the water management district agreement with the USACE, water quality certification will be considered waived when the permit or authorization expressly so states. The District most often expressly waives water quality certification for permits issued pursuant to the net improvement provisions and for projects that discharge into impaired waters. Proposed Specific Condition No. 9 of the permit expressly waives water quality certification due to the fact that the receiving waters are listed by DEP as impaired. Conditioning of the permit in this manner is consistent with DEP guidance and District practice under these circumstances. Although water quality certification for federal permitting review purposes is waived, the project must still comply with water quality requirements by demonstrating that the proposed activities do not cause or contribute to a violation of state water quality standards or if the activities contribute to an existing violation, that a net benefit is provided. The evidence establishes that the project will not cause or contribute to a violation of water quality standards and is not expected to contribute to the receiving water impairment of elevated mercury levels in fish tissue. While not required, the project is nevertheless expected to have a positive benefit on overall water quality and likely will reduce mercury levels in fish tissue by removing the sediments that contain metals such as mercury. The District's waiver of water quality certification is consistent with Section 401, the legislative declaration of policy set forth in section 373.016(3)(f) and (j), and applicable regulatory practices for Clean Water Act water quality certification.

The Issue The issues are whether Respondent Centex Homes is entitled to the issuance of an environmental resource permit to construct a 2665 square-foot boat dock and authorization of a lease of 7807 square feet of sovereign submerged land in the portion of the Intracoastal Waterway known as Lake Worth Lagoon in Palm Beach County.
Findings Of Fact In this case, Respondent South Florida Water Management District (District) has proposed to issue to Respondent Centex Homes (Centex) an environmental resource permit (ERP) and authorization to lease sovereign submerged land. The purpose of the ERP and lease authorization is for Centex to construct a dock to serve a multifamily development known as Ocean Cay. Ocean Cay is a 56-unit townhouse development located on a five-acre parcel in Hypoluxo, Florida, bordered on the west by U.S. Highway 1, on the east by the Lake Worth Lagoon, and on the north and south by developed residential areas. At the time of the hearing, Centex had closed on the sale of 50 of the residential units, was finishing construction of the final six units, and had entered into contracts to sell three of these six units. The Lake Worth Lagoon is a Class III water and is not an aquatic preserve. The Intracoastal Waterway channel is in the middle of the lagoon. The proposed dock would be about 1.5 miles north of the South Lake Worth Inlet (a/k/a Boynton Inlet) and 13 miles south of the Lake Worth Inlet (a/k/a Palm Beach Inlet). As measured from the project location to the opposite shoreline, the length of the dock is more than 25 percent of the width of the waterbody. Petitioner Michael C. Brown resides at 131 Las Brisas Circle, Hypoluxo, Florida. Intervenor O'Brien resides at 124 Park Lane East, Hypoluxo, Florida. Intervenors Evlyn and Vern Hakes reside at 140 Park Lane East, Hypoluxo, Florida. As stipulated by Respondents, Petitioner and Intervenors have standing, so this Recommended Order will not restate the substantial evidence in the record of the standing of Petitioner and Intervenors. Three of the objections raised by Petitioner and Intervenors involve procedural issues that are easily dismissed on factual grounds. The first objection is that Centex lacks the requisite equitable interest in the upland to obtain a lease of sovereign submerged land. The second objection is that the Ocean Cay Homeowners' Association lacks the financial, legal, and administrative resources to ensure the performance of all permitting obligations, as they may arise in the future. The third objection is that District staff, not the Governing Board of District, issued the proposed agency action on the ERP. As for the first procedural objection, Centex acquired the parcel by special warranty deed, which vests fee simple interest in Centex and contains all the customary warranties of title. The title insurance policy obtained by Centex for the parcel insures fee simple interest in Centex, subject to undescribed reservations contained in the deed from the Board Trustees of the Internal Improvement Trust Fund (Trustees), any part of the parcel lying below the mean high water line, and public rights "to use the waters over the submerged land lying adjacent to or within the Intercoastal [sic] Waterway for boating, fishing, swimming and other public purposes, together with the rights of the State of Florida and United States to regulate the use of the navigable waters." Not only does Centex enjoy full beneficial ownership of the upland, subject to the rights of its grantees who have purchased townhouse units, but Centex's title extends approximately 250 feet waterward of the mean high water line by operation of a deed from the Trustees to a predecessor in interest of Centex. If the ownership of submerged land between the submerged land for which an applicant seeks a lease and adjacent uplands also owned by an applicant has any effect at all, it only emphasizes the legitimate, nonspeculative interest of such an applicant in obtaining the sought-after lease. As for the second procedural objection, Centex is a sophisticated land-development entity with ample financial, legal, and administrative resources to ensure the satisfaction of any permitting obligations imposed upon it in connection with this case. At present, Centex controls the Ocean Cay Homeowners' Association. So, at present, the concerns of Petitioner and Intervenors about the ability of the homeowners' association to satisfy its obligations are unfounded. It is true that, upon the closing of the sale of sufficient units, Centex will transfer control of the homeowners' association to the homeowners. The record does not describe the financial, legal, and administrative resources of the homeowners' association following the withdrawal of Centex, but they will presumably not approach the substantial resources of Centex. District claims that Centex may not transfer the ERP without District's approval; however, ERP Special Condition 2 identifies the operating entity responsible for the docking facility as Ocean Cay Homeowners' Association, even though the ERP identifies the applicant as Centex. Fatal to the argument of Petitioner and Intervenors, though, are the facts that the proposed lease of sovereign submerged land is for only five years, a failure to discharge permit obligations that should be incorporated verbatim into the lease militates against any lease renewals, and the removal of the dock would substantially cure any deficiencies in its maintenance. As for the third procedural objection, District staff, on November 21, 2003, proposed to issue a standard general ERP for the construction and operation of a 2665 square-foot docking facility with nine boat slips for use by the residents of Ocean Cay and to approve the lease of 7807 square feet of sovereign submerged land under and surrounding the docking facility. Staff issues a proposed standard general ERP when a permit does not conflict with existing law or policy or a work of the District. District's Governing Board issues a proposed standard individual ERP in the relatively rare case in which a permit conflicts with existing law or policy or a work of the District. Again, the objections of Petitioner and Intervenors lack factual support. Here, the Governing Board, not staff, will receive the Recommended Order and issue the Final Order. So, as Petitioner and Intervenors wish, the Governing Board, not staff, will take the final agency action in this case. Under these circumstances, the record reveals no harm in the fact that District staff issued the proposed agency action. The remainder of the ERP provisions bears on the substantive objections raised by Petitioner and Intervenors. As amended at the final hearing by District and accepted by Centex, ERP Special Condition 9 provides: A permanent sign shall be installed at the docking facility entrance to notify boat owners that mooring at the docking facility shall be limited to no more than a total of nine vessels. Vessels moored in slips 1-2 and 7-9 shall be limited to outboard powered vessels, not more than 27 feet in length as reported by the manufacturer exclusive of engines and any bow pulpit. Vessels moored in slips 3 and 6 shall be limited to not more than 27 feet in length as reported by the manufacturer exclusive of engines and any bow pulpit. Vessels moored in slips 3 and 6 are not limited to outboard power. Vessels moored in slips 4 and 5 shall be limited to 36 feet in length, as reported by the manufacturer exclusive of engines and any bow pulpit. Vessels in slips 4 and 5 are not limited to outboard power. Slips are identified by number in the discussion below. As amended at the final hearing by District and accepted by Centex, ERP Special Condition 10 provides: "Dock, walkway, and seagrass sign pilings shall be constructed of plastic, concrete or greenheart, non-CCA treated wood or wood wrapped in 30 to 60 mil pvc." ERP Special Condition 11 provides that construction of the dock shall be in accordance with the locations and dimensions shown on the enclosed exhibits. The referenced drawings depict the adjacent upland, submerged bottom, and proposed dock. The drawings describe sufficient detail of the adjacent upland. The north and south property lines of the 190- foot wide parcel run due east and west. At mean high water, the parcel's shoreline runs about 210 feet in a south-southwesterly direction from the north property line. Waterward of the mean high water line is a thin band of sand, varying portions of which are exposed between mean high water and mean low water. The drawings describe the submerged bottom in great detail as to seagrass and reasonable detail as to water depths. Waterward of the beach is a band of Halodule wrightii (shoal grass). The drawings describe the shoal grass in this area as "sparse." The drawings depict mean low water depths along three transects at 25-foot intervals, starting roughly at the landward commencement of the shoal grass. (All water depths are based on mean low water.) If the property lines were extended into the water, the north transect is 25 feet south of the north property line, and the south transect is 25 feet north of the south property line. The middle transect is an equal distance between the north and south transects. Along the north transect, the band of shoal grass is about 25 feet wide. Along the south transect, the band narrows to about six feet wide. Along the middle transect, the band is about 50 feet wide. Waterward of the band of sparse shoal grass, according to the drawings, is a band of "mixed Halodule and sparse Johnson's." The reference to "Johnson's" is to Halophila johnsonii (Johnson's grass), which is a rare species of seagrass that is listed by the U.S. Environmental Protection Agency as threatened. 50 C.F.R. § 17.12(h). Johnson's grass is found only on the east coast of Florida from the Indian River Lagoon to Biscayne Bay and is a fragile species of seagrass. The band of mixed shoal grass and sparse Johnson's grass reflects the same pattern as the shoal grass closer to shore: thinner at the north and south ends and wider in the middle. Along the north transect, the band of the two species is about 162 feet wide. Along the south transect, the band is about 212 feet wide. Along the middle transect, the band is about 240 feet wide. Waterward of the middle band of mixed shoal grass and sparse Johnson's grass, according to the drawings, is "scattered isolated blades of H. Decipiens and [Johnson's grass]." "H. Decipiens" is Halophila decipiens (paddle grass). Waterward of the north and south ends of the mixed shoal grass and sparse Johnson's grass are triangular-shaped areas of "sparse Johnson's." Along the north transect, this band of sparse Johnson's grass is about 75 feet wide. Along the south transect, this band of sparse Johnson's grass is about 50 feet wide. Waterward of these bands of sparse Johnson's grass is "scattered, isolated blades of H. Decipiens and [Johnson's grass]." Measured from the mean high water line, the band of mixed shoal grass and sparse Johnson's grass extends about 275 feet along the north transect, 312 feet along the middle transect, and 300 feet along the south transect. Water depths are shallow throughout almost the entire project area. Starting from shore, water depths are almost entirely less than 1.0 feet within the area of sparse shoal grass, although depths reach 1.2 feet along the middle transect. Proceeding waterward along the north transect, the depths within the area of mixed shoal grass and sparse Johnson's grass range from 0.7 feet at the landward end to 2.2 feet at the waterward end. Proceeding waterward along the middle transect, the depths within the area of mixed shoal grass and sparse Johnson's grass range from 1.2 feet to 4.2 feet. Proceeding waterward along the south transect, the depths within the area of mixed shoal grass and sparse Johnson's grass range from 1.0 feet to 2.7 feet. The water continues to deepen in the triangular-shaped areas of sparse Johnson's grass, through which the north and south transects run. Along the north transect, the water depths range from 2.2 feet to 3.1 feet. Along the south transect, the water depths range from 2.7 feet to 3.6 feet. The drawings depict depths waterward of the start of scattered, isolated blades of paddle grass and Johnson's grass. These reported depths extend to a point roughly parallel to the end of the proposed dock along the north transect, about 12 feet waterward of the end of the proposed dock along the middle transect, and about 37 feet waterward of the end of the proposed dock along the south transect. Along the north transect, the depths remain constant, at about 3.5 feet, until the most waterward 25 feet, along which the water deepens 0.5 feet to 4.1 feet. Along the middle transect, the depths deepen about 0.5 feet to around 5.0 feet for about 75 feet, then deepen to 5.4 feet a few feet landward of the most waterward portion of the dock. About 10 feet waterward of the end of the dock, the depth reaches 5.7 feet, which is the deepest reported depth in the project area. Along the south transect, the depths deepen about one foot over the first 100 feet waterward from the start of the scattered, isolated blades of paddle grass and Johnson's grass. From a point parallel to the end of the dock, the water along the south transect deepens another 0.5 feet to about 5.2 feet. The drawings also describe the proposed dock in great detail. The dock, oriented due east and west, runs a distance of 420 feet from its landing, at the mean high water line, to its waterward terminus. The dock is four feet wide, except for a 10-foot long section, at about midpoint, that is six feet wide to facilitate wheelchair access. At the urging of District, to reduce seagrass impacts, Centex moved the dock ten feet south and extended it ten additional feet into deeper water. Because of the former of these modifications, the dock runs ten feet south of the middle transect. The main deck of the dock is grated, so as to allow at least 46 percent of the light to pass through it, from the waterward extent of the sparse shoal grass to the waterward extent of the mixed shoal grass and sparse Johnson's grass, which is a distance of about 250 feet. Although the drawings specify only a value of 46 percent light transmissibility, testimony established that this criterion would require the use of fiberglass decking material. Perhaps the most prominent feature of the dock, in addition to its length, is its height. The deck is five feet above mean high water. Mean high water is 1.7 feet National Geodetic Vertical Datum (NGVD). Mean low water is -0.8 feet NGVD. Five decks run perpendicular to the main deck--three on the south side and two on the north side--to form the slips at the waterward terminus of the dock. The most landward of these decks is four feet wide and 30-feet long and runs south of the main deck, at a point about 330 feet waterward of the landing. Two more decks, both of the same dimensions as the first deck, join the main deck at a point about 375 feet waterward of the landing. Thirty-eight feet separate the two southern decks, so that the two slips created between them (Slips 9 and 8, from landward to waterward) each is 18-19 feet wide. The most landward slip formed north of the main deck (Slip 1) is also 18-19 feet wide. Two pilings north of the main deck and two pilings south of the main deck define these first three slips. The remaining perpendicular decks form the terminus of the entire dock. These decks are eight-feet wide and run 38 feet north and 38 feet south of the edges of the main deck. The four slips immediately landward of these decks are 18-19 feet wide. Moving clockwise from the northwest corner, these slips are Slips 2, 3, 6, and 7. The remaining two slips are waterward of the eight-foot wide deck. The northern slip is Slip 4, and the southern slip is Slip 5. According to the drawings, the waterward extent of the proposed lease is 18 feet waterward of the waterward end of the dock. The waterward extent of the proposed lease is 425 feet from the landward end of the Intracoastal Waterway channel (the 415 feet shown in the drawings is wrong), which, as established by testimony, is 125 feet wide at this location. The drawings also depict a 42-inch high handrail running from the landing to the most landward perpendicular deck. The purpose of the handrail, whose vertical slats are eight inches apart, is to discourage mooring of vessels to the main dock landward of the slips. Every 50 feet, at the base of the handrails on either side of the dock, is a sign prohibiting docking, mooring, loading, or unloading of vessels. At the terminus of the dock, the drawings show a rock crib structure that rises about one foot from the submerged bottom along the entire 80-foot length of the eight-foot wide perpendicular deck. Apparently, the rock crib is eight-feet wide, so that it extends, beneath the surface of the water, under the entire area of the eight-foot wide perpendicular deck. Extending above the rock crib, along this 80-foot long deck, is a wave attenuator. The drawings also depict a couple of seagrass warning signs north and south of the dock, about 20-30 feet waterward of the waterward extent of the sparse Johnson's grass, at the north and south portions of the project area, and the mixed shoal grass and sparse Johnson's grass, in the middle of the project area, just a few feet north of the dock. The drawings also show pilings at a minimum of 10-foot intervals along the entire length of the main deck, as well as pilings for the perpendicular decks at the dock's terminus. Special Condition 12 prohibits fueling facilities or hull-painting or -cleaning at the dock. Special Condition 13 prohibits liveaboards. Special Condition prohibits subleasing of the docking facilities and limits their use to residents of Ocean Cay. Special Conditions 14 and 15 detail various manatee- protection provisions. Special Condition 19 requires the implementation of a turbidity-control plan during construction. Special Condition 18 prohibits construction under the ERP until the Department of Environmental Protection has issued a submerged land lease. As amended at the final hearing by District and accepted by Centex, Special Condition 20 requires Centex to maintain at least one trash receptacle at the terminus of the dock. The District staff report states that Centex has minimized the impacts of the project by reducing the length of the dock from 550 feet and its capacity from 22 slips. The staff report notes, as mentioned above, the relocation of the dock ten feet to the south and ten feet waterward, both changes to reduce impacts on seagrasses. The District staff report states that manatees probably use the area of the project for travel and foraging nearshore seagrass beds. Concerning the lease of sovereign submerged land, the District staff report acknowledges the waterward extent of Centex's ownership of submerged lands. As for the sovereign submerged land, the District staff report states, without explanation, that the docking facility is not more than 25 percent of the width of the "navigable portion of the waterbody," pursuant to Florida Administrative Code Rule 18-21.004(4)(a)3, and is more than 100 feet from the federal navigation channel, as required by Florida Administrative Code Rule 18-21.004(4)(a)4. The District staff report attaches "Recommended Special Lease Conditions for Ocean Cay." These include a restriction that vessels moored at the dock clear the submerged bottom by at least one foot at all times while moored. Other provisions correspond to the special conditions attaching to the ERP, as described above. As discussed in the Conclusions of Law, analysis of the proposed activity requires three determinations: first, does the proposed activity, unmitigated, adversely impact surface waters; second, if so, has Centex reduced or eliminated all such impacts through design modifications to the extent practicable; and third, if so, but if net impacts remain, has Centex adequately mitigated these net impacts? Absent mitigation, the construction of a 420-foot dock covering 2665 square-feet of water adversely impacts the water resources, most obviously by the immediate destruction of the seagrasses occupying the area in which at least 80 pilings will be installed and by the gradual destruction of the seagrasses that will be shaded by the dock and lose the light necessary for survival. Centex has incorporated into the proposed dock design all practicable modifications that could eliminate or reduce these adverse impacts to the surface waters. Centex has proposed a dock that is narrow, high, translucent, and nontoxic. To minimize the risk of prop dredging of the seagrass and bottom sediments, the dock's length and railings would limit mooring to relatively deeper water, and the boat-length restriction would effectively limit the reach of prop dredging. Even after these design modifications, however, adverse impacts to the surface waters remain that Centex must mitigate. The ultimate issue, then, is whether Centex has adequately mitigated the remaining impacts of the proposed activity by proposing sufficient affirmative acts to offset the remaining adverse impacts. Strictly speaking, mitigation consists of activities that are unnecessary for the desired activity--here, the construction of a dock--but are performed to offset the adverse impacts of the desired activity. In this case, Centex proposes three mitigation activities: the construction of a rock crib, the installation of a wave attenuator, and the erection of two seagrass warning signs. The adequacy of this proposed mitigation requires identification of the specific impacts to the surface waters and the efficacy of the mitigation in offsetting these impacts. As cited in the Conclusions of Law, the public-interest criteria set forth the elements requiring consideration. Except to the extent discussed in navigation, the dock will not adversely affect the public health, safety, or welfare or property of others. The narrow, long dock, which restricts mooring activity to its terminus over 400 feet from the shoreline, has no impact on the riparian rights of adjacent or nearby upland owners. Thus, no mitigation is necessary for this criterion. Even after mitigation, the dock will adversely affect the conservation of fish and wildlife, including listed species, and their habitats. The most immediate impact of the dock is upon the seagrasses that presently grow on the bottom. Seagrasses, which are among the most productive communities known to nature, are vital to the health of the Lake Worth Lagoon. Seagrasses perform numerous functions important to the surface waters and, specifically, the conservation of fish and wildlife and their habitats: shelter for small fish and shellfish; food for a variety of small and larger organisms, including manatee and sea turtles; stabilization of bottom sediments, which improves water clarity; recycling of nutrients, including nitrogen--an important function for the water quality of the nitrogen-limited Lake Worth Lagoon; and formation of a substrate on which epiphytes may attach and provide food for a variety of organisms, including manatee and sea turtles. The mitigation activities offset some, but not all, of the functions provided by the seagrass that are lost by the construction of the dock. The rock crib probably will replace the function of the seagrass in stabilizing sediments. The rock crib probably will replicate some of the shelter function of the seagrass, although nothing in the record would support a finding that the crevices of the rock crib provide exactly the same shelter as the seagrass patches that will be destroyed by the dock. Thus, there is no basis to assume that the shelter functions of the seagrass are replaced by the shelter functions of the rock crib. Undoubtedly, the rock crib will not replace the food function of the seagrass. Some predators may find the same juvenile fish in the rock crib as they have found in the seagrass, and some organisms may find the same epiphytes attaching to the rock crib as they have found attaching to the seagrass. However, the organisms, such as manatee and sea turtles, that eat the seagrass itself will find the rock crib a poor food substitute. Additionally, the rock crib will perform none of the nutrient-fixing that seagrasses perform. The rock crib thus fails to perform the vital functions of seagrass in providing food for important species, such as the manatee, and fixing nutrients, which is important to improving or maintaining water quality. The wave attenuator is a potentially useful form of mitigation. Although a slight over-generalization, the seagrass thins to the point of near disappearance at a point in which the slope of the submerged bottom breaks--very roughly at about three feet deep. Centex's witnesses offered the better explanation of this phenomenon by linking it to the strong wakes produced by vessels motoring in the Intracoastal Waterway. Although the area of the proposed project is permanently slow speed, no wake, the Intracoastal Waterway channel has no speed limit, and the wakes from vessels in the channel pound the shallows, focusing considerable energy upon the rising bottom at the point at which the water depth reduces to three feet. The main problem with the wave attenuator as mitigation is one of scale. Nothing in the record suggests that the attenuator, even in conjunction with the rock crib beneath it, will attenuate the incoming waves along the entire length of the dock. The attenuator will absorb the energy of the waves, whether from passing vessels or storms, but the interrupted waves will rejoin a short distance landward of the attenuator, possibly waterward of the first appearance of significant seagrass. The wave attenuator is thus inadequate in preserving or enhancing the remaining seagrass following the construction of the dock. The signs suffer two shortcomings. First, they are as likely to attract fishers as they are to deter recreational boaters, so the record permits no finding as to their efficacy in preserving or enhancing the remaining seagrass following the construction of the dock. Second, the record discloses little prop dredging of the seagrasses in the proposed vicinity of the dock, so the effect of the signs is not to ameliorate the damage historically done in this area by boats. To the contrary, at best, the signs may reduce some of the prop dredging that would occur in the future by boats drawn close to shore by the presence of the dock, which will attract fish and, thus, fishers. For these reasons, the signs are inadequate mitigation. Considered in conjunction with each other, the three mitigation activities fail to address the important food and nutrient-fixing functions of the seagrass that would be destroyed by the dock. Ignoring the failure of the proposed mitigation to address two of the most important functions of the seagrass, District and Centex contend that the mitigation is adequate for other reasons. District and Centex contend that the loss of seagrass is de minimis, consisting of not more than .03 acres of destroyed seagrass, or about 2.2 percent of the seagrass in the project area. Although the east-west orientation of the dock results in more shading than an identical dock oriented north- south, the shading loss could be less due to commendable design modifications involving the width, height, and translucent materials of the dock. Adding to the loss of seagrass from shading is the loss from the "halo effect," which is the wider area of seagrass loss probably resulting from the effect of the dock in artificially attracting and retaining seagrass consumers, like parrot fish. The record thus affords no basis for a finding of a loss of less than .03 acres. Nor does the record afford any basis for determining that the seagrass loss is de minimis. If Lake Worth Lagoon has seagrass to spare, the record does not support such a finding. If the lost functions of the seagrass--primarily, providing food and fixing nutrients--are not de minimis, the question remains whether practicable mitigation for these functions exists. Although transplantation of seagrass may be impracticable due to poor water clarity, even one of Centex's experts noted the importance of filling holes for seagrass recruitment, given the inability of seagrass to extend roots laterally up or down slopes. District's expert identified backfilling submerged holes and scraping spoil islands as two means of encouraging natural seagrass recruitment. District's expert noted a practical consideration favoring rock cribs versus more elaborate, higher-maintenance mitigation. Rock cribs are low- or no-maintenance projects that require no monitoring, enforcement, or enhancement. However, these same considerations underscore the complexity of the functions provided by seagrass lost to the proposed activity. Mitigating the loss of these functions may be difficult and high-maintenance, if the mitigation is to offset the loss. On this record, a finding of impracticability of such mitigation activities would be speculative, given the absence of evidence of impracticability, such as in the form of the absence of nearby depressions with suitable recruitment conditions or seagrass restoration projects in which Centex could participate. An unusual factor militating against a finding of adequate mitigation is that one of the seagrasses is itself a protected species. Johnson's grass is rare and fragile. The dock would displace Johnson's grass in a location less than one mile north of one of ten federally designated Critical Habitats for Johnson's Seagrass and one of two such habitats in Lake Worth Lagoon. 50 C.F.R. § 226.213(h). In contrast to the permit conditions directly protecting the manatee, the record is silent as to any effort by District to coordinate this permit with the work of the federal government and possibly the state and local governments to preserve Lake Worth Lagoon's seagrass, including the threatened Johnson's grass. On balance, even after mitigation, the dock will adversely affect the conservation of fish and wildlife, including listed species, and their habitats. The dock will not adversely affect navigation, the flow of water, and erosion or shoaling. Located only 1.5 miles from the inlet, tidal flows are good in the project area. The rock crib and wave attenuator, which tend to restrict east-west flows and waves, will have little impact on the tidal flows, which are predominantly in a north-south direction. The dock will not cause any erosion or shoaling. The dock will be lighted and should not present a navigation hazard. Larger vessels will remain a safe distance from the dock as they travel in the Intracoastal Waterway channel. Under normal boating conditions, small boats, such as kayaks, canoes, and small motorboats, can safety navigate under the five-foot deck and between the pilings spaced at a minimum distance of ten feet apart. The dock will not adversely affect the fishing or recreational values in the vicinity. To the contrary, the structure provided by the dock will probably attract and concentrate fish, making them easier to catch. In the longer term, even after mitigation, the dock will adversely affect marine productivity for the reasons discussed in connection with the conservation of fish and wildlife and their habitat. The dock will not adversely affect any historical or archaeological resources. Even after mitigation, the dock will adversely affect the current conditions and relative value of functions for the reasons discussed in connection with the conservation of fish and wildlife and their habitat. For the reasons set forth above, Centex has failed to provide reasonable assurance that the proposed activity, even after mitigation, is not harmful to the District's water resources, is not inconsistent with District's overall objectives, is not contrary to the public interest, will not adversely impact the value of functions provided to fish and wildlife and listed species by surface waters, and will not cause adverse secondary impacts to the water resources
