The Issue The issue to be determined in this case is whether the Respondents, Florida Department of Transportation (“FDOT”) and Palm Beach County (also referred to as “the Applicants”), are entitled to the issuance of an Environmental Resource Permit (“ERP”) to construct an extension of State Road 7 (“SR 7”) and its associated surface water management system in Palm Beach County.
Findings Of Fact The Parties The City is a municipality incorporated under Florida law. The District is a regional agency with the authority to regulate the construction, operation, and maintenance of any surface water management system pursuant to chapter 373, Part IV, Florida Statutes, and Florida Administrative Code Titles 40E and 62. FDOT is an agency of the state of Florida charged with the establishment, maintenance, and regulation of public transportation. It is a co-applicant for the ERP permit. Palm Beach County is a political subdivision of the State of Florida, and is a co-applicant for the ERP permit. Background State Road 7 Extension The ERP was issued by the District for an 8.5-mile extension of SR 7 between Okeechobee Boulevard and Northlake Boulevard in Palm Beach County. The purpose of the proposed roadway is to relieve traffic now moving through rural residential areas and two large residential developments known as The Acreage and Jupiter Farms. The proposed roadway would also improve hurricane evacuation by providing additional capacity and connectivity, and reduce emergency response time in the rural residential areas. The proposed roadway alignment was selected by FDOT after a multiyear corridor study under a National Environmental Protection Policy Act process. Four corridors were considered using federal selection criteria that addressed social, environmental, property, physical, and financial impacts. There are two segments of the proposed roadway covered by the ERP. The southern segment would add two more lanes to the existing two-lanes of SR 7 from Okeechobee Boulevard North to 60th Street North, just south of the M-Canal. This segment is 4.4 miles long. The southern segment is not at issue in this case. The northern segment would extend four lanes of SR 7 east from 60th Street North about one mile, and then north 3.1 miles to Northlake Boulevard. This is the roadway segment challenged by Petitioner. Hereafter, all references to “the Project” are to the northern segment. The Project includes a raised roadway, median, sidewalks, bike lanes, and stormwater swales. It also includes a bridge over the M-Canal and a bridge over a water control outfall. The Project would be constructed in an existing right- of-way (“ROW”). FDOT owns a ROW that is approximately 200 feet wide. The County owns an adjacent 120-foot-wide ROW, so that the total width of the Project ROW is 320 feet. Running north/south within the ROW is a dirt service road, a ditch, and a fence. Much of the vegetation in the ROW is dominated by invasive and exotic plant species, including Melaleuca, Carolina Willow, Brazilian Pepper, and Australian Pine. The Ibis Development West of the Project ROW is the 1,958-acre Ibis Golf and Country Club residential development (“Ibis”). In 1989, an ERP was issued for Ibis’ surface water management system (“the Ibis system”). The Ibis system includes almost 300 acres of interconnected lakes that provide water management and water quality treatment for Ibis. The 1989 permit required the Ibis system to be sized to receive and treat runoff from a segment of Northlake Boulevard and from an existing two-lane road off of Northlake Boulevard that serves the commercial area of Ibis, which is directly north of the Ibis residential area. The Ibis system was also required to receive and provide water treatment and storage for the stormwater runoff from 46.8 acres of the ROW for SR 7. The parties introduced evidence about modifications to the 1989 permit, which the City contends reduced the treatment capabilities of the system. It is found from the preponderance of the evidence that the original system and its modifications continued to meet design requirements to store and treat future runoff from 46.8 acres of the SR 7 ROW.1/ When the water in the Ibis lakes reaches elevation 17.5 feet NGVD (National Geodetic Vertical Datum), pumps at two pump stations at the south end of Ibis begin pumping water over a berm into Ibis Preserve, a 366-acre natural area directly south of Ibis. Water is retained in Ibis Preserve unles it exceeds an elevation of 18.5 feet, when it then passes over an outfall structure into the Grassy Waters Everglades Preserve (“Grassy Waters”) to the east. Ibis Preserve provides additional water quality treatment for the water pumped from Ibis, but this additional treatment was not part of the calculation of water quality management for Ibis. The Ibis system was required to meet District permitting criteria before discharge to Ibis Preserve. The North Palm Beach County Improvement District (“Improvement District”) owns and has operational and maintenance responsibility for the Ibis system. It also owned and managed Ibis Preserve, but transferred ownership and management of Ibis Preserve to the City in 2004. Grassy Waters/Water Catchment Area To the east of the Project is the City-owned “Water Catchment Area,” which covers about 14,700 acres or 23 square miles. The Water Catchment Area is owned by the City and is part of its public drinking water supply system. Water in the Water Catchment Area flows to Lake Mangonia where it is withdrawn, treated, and then delivered to residents and businesses in the City, the Town of Palm Beach, and the Town of South Palm Beach. There is a statement in the Project application that Grassy Waters refers only to the open water marsh within the Water Catchment Area. The Water Catchment Area includes other habitat types besides open marsh. Most of the information in the record indicates that Grassy Waters and the Water Catchment Area have the same boundaries. Therefore, in this Recommended Order, Grassy Waters and the Water Catchment Area are treated as being two names for the same area. Grassy Waters was once connected to the Everglades and large portions of it have the same characteristics, being an open water marsh with an extended hydroperiod. It is oligotrophic, meaning it is low in nutrients and has an ecosystem adapted to low nutrient conditions. It was undisputed that most areas of Grassy Waters are of high or even pristine environmental quality. Grassy Waters has periphyton, an assemblage of algae that only survive in phosphorous levels of less than 10 parts per billion (“ppb”). Periphyton is the base of the food chain in the open water marsh area of Grassy Waters and is consumed by apple snails and many invertebrates and fish. Grassy Waters has a visitor and nature center and provides recreational opportunities, such as canoeing, hiking, and bird watching. There appeared to be disagreement about whether the Project ROW is located in Grassy Waters or adjacent to it. The ROW is not within Grassy Waters, it is adjacent. However, the wetlands and other surface waters within the ROW are hydrologically connected to Grassy Waters. In the western part of Grassy Waters, which ends at the Project ROW, there are hammock islands and hydric pine flatwoods. The City contends these areas and the rest of the ROW were historically open water marsh, but were changed by human activities. The more persuasive evidence is that this western area was not all open marsh, historically. It was an area of natural transition from open water marsh to other habitat types. Ibis Impacts to Grassy Waters The parties disputed whether the Ibis system is a “failed system.” This is not a technical or defined term. The relevant issue is whether the Ibis system is operating in conformance with the requirements of its permit. The City contends the Ibis lakes are eutrophic and that sediment accumulation in the lakes is releasing phosphorus back into the water, which ends up in Grassy Waters. However, the City’s expert witness, Dr. Harper, admitted that the phosphorus concentration being discharged from the Ibis system, about 40 ppb, is typical for surface water management systems serving large residential developments, although that concentration is at the high end of the range. The phosphorus concentration is closer to 30 ppb in discharges from Ibis Preserve into Grassy Waters, showing that Ibis Preserve provides additional treatment to the waters coming out of Ibis. The characterization of the nutrient loading from the Ibis system as “typical” did not address the additional nutrients in the drainage that the Ibis system is required to accept from the SR 7 ROW. The record does not show that the nutrient concentrations from the Ibis system would still be typical if all of the ROW drainage were added without pre-treatment, as was contemplated by the 1989 Ibis permit. Because Grassy Waters is an oligotrophic ecosystem, it can be adversely affected by phosphorus levels above 10 ppb. When phosphorus is introduced into an oligotrophic system in concentrations over 10 ppb, the system begins to change to denser wetland vegetation, which can include invasive and nuisance species, such as cattail. There is denser vegetation and cattails in Grassy Waters near the Ibis Preserve outfall. There is also more phosphorus in sediments near the outfall. These effects decrease with distance from the outfall, but some effects were detected as far as a half mile from the outfall. The City’s expert witness, Dr. Gaiser, testified that periphyton is dissolved by high nutrient levels and replaced by weedy algae. She found adverse effects on periphyton near the outfall. Dr. Gaiser also found microcystis near the outfall. Microcystis is a toxic algae caused by high elevations of phosphorous. Microcystis comprised over 10 percent of the cell density of the algal community near the outfall. The District’s witness, Mr. Waterhouse, conceded that there is a problem with nuisance vegetation at the discharge point into Grassy Waters. He said the District was not aware of the problem before information was developed for this case. No evidence was presented about what consideration the District gave in 1989, when Ibis was permitted, to the potential adverse impacts of discharging phosphorus into the oligotrophic ecosystem of Grassy Waters. Based on the evidence that a phosphorus concentration of 30 ppb is expected for this kind of surface water management system, it must be concluded that the Ibis system was not designed to prevent harm to oligotrophic receiving waters. Respondents presented evidence to show that phosphorus loadings from the M-Canal could be the cause of the adverse impacts found near the Ibis Preserve outfall. The M-Canal was constructed by the City for the primary purpose of delivering water from Lake Okeechobee, via connection to the L-8 Canal, to the Water Catchment Area for public water supply. For most of its length, the M-Canal runs through Grassy Waters. The City generally maintains the water level in the M-Canal below the elevation of Grassy Waters so water in the canal will not flow into Grassy Waters. However, on some occasions, water flows from the M-Canal into Grassy Waters. High phosphorus concentrations have been recorded in the M-Canal; as high as 300 ppb. Nuisance vegetation is growing in the area where the M-Canal connects to the Water Catchment Area. The preponderance of the evidence establishes that the adverse impacts described by the City’s experts in the area of the Ibis Preserve outfall are caused primarily by discharges from Ibis Preserve. There are three other developments adjacent to Grassy Waters that occasionally discharge to Grassy Waters. These discharges are likely to contain some nutrients, but the amount of nutrients and their effects, if any, on Grassy Waters were not described in the record. The Water Catchment Area is a Class I waterbody because it is used for public water supply. The water quality standard for phosphorus and other nutrients in a Class I waterbody is set forth in Florida Administrative Code Rule 62-302.530(48)(b): In no case shall nutrient concentrations of a body of water be altered so as to cause an imbalance in natural populations of aquatic flora or fauna. Grassy Waters was designated by the Department of Environmental Protection (“DEP”) as a stream. Rule 62-302.531(2)(c) states that the narrative criterion “shall be interpreted as being achieved in a stream segment where information on chlorophyll a levels, algal mats or blooms, nuisance macrophyte growth, and changes in algal species composition indicates there are no imbalances in flora or fauna.” The City presented some evidence regarding nuisance macrophyte growth and changes in algal species composition in Grassy Waters near the Ibis Preserve outfall. Little evidence was presented regarding the practice of DEP or the District in the application of the narrative nutrient standard, but the preponderance of the evidence indicates the agency practice is to consider a stream segment as a whole to determine whether it exhibits an imbalance in natural populations of aquatic flora and fauna.2/ During the course of this proceeding, the District issued administrative complaints against the Improvement District and the City, which include Orders for Corrective Action. The complaints were issued pursuant to section 373.119, Florida Statutes, which authorizes such action when a water management district believes that a violation of any provision of chapter 373 or district rule has occurred. However, at the final hearing, the District was reluctant to say the Improvement District had violated any law or permit condition. The Improvement District did not challenge the enforcement action against it and, therefore, the District’s enforcement order became final. The Improvement District is required to address the accumulation of sediment in the Ibis Lakes, develop a nutrient source control plan, eliminate and reduce the use of herbicides containing copper sulfate, and reassess pumping schedules. There is no target nutrient limit specified in the District’s Orders for Corrective Action. The District’s enforcement action against the City seeks to require the City to increase secondary treatment and retention in Ibis Preserve, provide a plan to remove the exotic/invasive vegetation at the outfall, provide a vegetation monitoring plan, and develop source control measures for residential developments that discharge into Grassy Waters. The City challenged the enforcement action and it remains pending. Snail Kites The Everglades snail kite gets its name from its primary food, the apple snail. In the Everglades, snail kites also feed on an exotic island snail, which occurs there in about equal numbers as apple snails. There was no evidence presented that there are exotic island snails in Grassy Waters. Snail kite habitat is dependent on conditions conducive to apple snails, which are the open marsh and oligotrophic conditions where periphyton flourish. If a sufficient number of apple snails are present, snail kites will find suitable nesting nearby. Dense wetland vegetation is not good forage for snail kites because, even if apple snails are present, the apple snails will be difficult or impossible for the snail kites to see. Dr. Welch, who was the state snail kite conservation coordinator at the Florida Fish and Wildlife Conservation Commission and wrote the snail kite management plan for Florida, testified for the District, where he is now employed as a senior scientist. He said field surveys of snail kite nests in Grassy Waters indicate their numbers are relatively low compared to other areas where snail kites are found. There were only ten successful nests (eggs laid) observed from 2000 to 2016. The City’s Everglades expert, Dr. Lodge, speculated that the low nest counts could be due to difficulty in seeing the nests, but he was not familiar with the survey techniques used and, therefore, his opinion that the numbers could be materially underestimated is not credited. Snail kites nest throughout the Water Catchment Area, but primarily in the open marsh areas of the central and eastern portions of the Water Catchment Area. Over 90 percent of snail kite nests are more than a mile from the Project ROW. Dr. Lodge said there are four snail kite nests within 800 feet of the Project, but he was not more specific about their locations. Most nests are closer to Northlake Boulevard, State Road 710, and the Florida Turnpike. The major factor that adversely affects successful nesting by snail kites and production of offspring is predation, usually by raccoons and rat snakes. “Cold snaps” and drought are also factors. Impacts of The Proposed Project Water Quantity Impacts Water storage for the Project, which was going to be handled in the Ibis system under the 1989 Ibis permit, would be provided in the roadside swales. The Project is designed to retain water volumes greater than typically required for roadways. Stormwater would not flow out of the Project into the Ibis system except in unusually large storm events, in excess of six inches of rainfall. The City did not dispute the Project’s compliance with the applicable water quantity criteria in the District rules. Water Quality Impacts To address the City’s concerns about adverse impacts caused by the Ibis system, the Applicants expanded the roadside swales by ten feet and raised the outfall elevation by 0.05 feet. With these modifications, the Project would provide water quality treatment for its stormwater and no longer rely on the Ibis system for treatment. The swales would provide treatment in excess of the treatment required by District rules. Respondents contend that, when the treatment provided by the Ibis system is added, the total treatment provided for the Project stormwater is more than twice as much as required by District rules. The City, on the other hand, claims that no additional water quality treatment can be provided by the Ibis system because the Ibis Lakes are eutrophic. The preponderance of the evidence supports a finding that Project runoff to the Ibis system would receive additional water quality treatment in the Ibis system and in Ibis Preserve before flowing to Grassy Waters. The effect of the Project’s on-site treatment of its stormwater is that the amount of nutrients that would otherwise flow into the Ibis system from SR 7 would be reduced. Therefore, the effect of the Project is to reduce the nutrient load that the Improvement District was permitted to discharge to Ibis Preserve and Grassy Waters. The City did not dispute the Applicants’ evidence that the Project exceeds the District’s design criteria for water quality. The City focused instead on its contention that, despite its compliance with water quality design criteria, the Project would result in additional nutrient loading to Grassy Waters, which would cause additional adverse impacts to its flora and fauna. The Applicants and the City performed nutrient loading analyses even though such analyses are only required by the District when the receiving waters have been designated by the Department as “impaired” by nutrients or in the case of certain other specially designated waters. Grassy Waters does not have any of these special designations. The Applicants’ nutrient loading analysis concluded that the post-development loading of phosphorus and nitrogen from the Ibis system would be less than the pre-development condition, so there would be a net decrease in nutrients discharged into Grassy Waters. Petitioner’s expert witness, Dr. Harper, believes the Project would increase nutrient loading to Grassy Waters, even if stormwater from the Project did not carry additional nutrients, because the increased volume of water moving through the Ibis system would entrain more nutrients from sediments in the Ibis lakes. Dr. Harper believes the Project would also cause nutrient loading via groundwater seepage through the roadway swales into Grassy Waters. The preponderance of the evidence does not support his opinion that groundwater seepage would cause additional nutrient loading.3/ Dr. Harper believes another source of nutrient loading from the Project would be from surface flow down the roadway embankments. On the eastern embankment, this flow would enter the mitigation area 150 feet from Grassy Waters. Dr. Harper’s estimated total loading from all sources is not persuasive. The estimate gives a false sense of precision. It is based on a number of variable assumptions, some of which are not widely known or in use by experts in the field. In addition, Dr. Harper’s opinion did not appear to appropriately account for the modifications to the Project’s storage capacity. Dr. Harper’s estimated loading was not translated into physical effects in Grassy Waters. The Applicants’ estimate of total nutrient loading also gives a false sense of precision, but it is based on a well-known and widely used methodology. The City failed to prove that the Project would result in more nutrient loading to Grassy Waters than is currently contributed by the ROW. Because the Project would not rely on the Ibis system for stormwater treatment, the Project would reduce the loading that the Improvement District was permitted to discharge to Grassy Waters. To address potential vehicular spills into Grassy Waters, FDOT produced a Spill Response Plan. The swales would capture and contain any material spilled on the roadway or swale. The curb and gutter, a guardrail, gravity wall, and fence also provide protection against spills. The bridge over the M-Canal would use a 54-inch traffic barrier, which is higher than FDOT specifications for the design speed for the bridge. The City did not present evidence to show that the protective measures proposed by the Applicants are less than what is usually considered adequate under similar circumstances, or fails to meet a relevant safety standard. Wetland Impacts Direct Impacts The Project would directly impact 52.37 acres of wetlands and 7.86 acres of surface waters. The impacted wetlands are fresh water marsh, mixed shrubs, and hydric pine flatwoods. The surface waters affected consist of vegetated ditches and un- vegetated channels or canals. The impacted wetlands include 11.77 acres of freshwater marsh. The impacted surface waters are ditches. Most of these wetlands are disturbed and their functional values have been reduced. Secondary Impacts District rules require an applicant to account for the secondary impacts caused by a project that could adversely affect the functions of adjacent wetlands or other surface waters. The Applicant’s Handbook defines secondary impacts to include impacts on wetland functions, water quality, and endangered species, including impacts on areas needed by endangered species for foraging. Part of the Applicants’ assessment of secondary impacts of the Project was made by reviewing the effects of the Acreage Reliever Road on Pond Cypress Preserve, a 1,737-acre conservation area managed by the County that is immediately south of the proposed Project. The County has been monitoring the effect of the Acreage Reliever Road on hydrology, vegetation, and species compensation ever since the road was built. The County found no adverse secondary impacts caused by the road. The species that use the wetlands near the road, including wading birds, appear to be unaffected by the road. The scoring of secondary impacts for the Projects, using the Uniform Mitigation Assessment Methodology (“UMAM”), was conservative, meaning that assumptions were made at the high side of the potential range of impacts. This resulted in more mitigation being required. The Applicants claim the Project would “maintain a 300-foot buffer between the project’s construction boundary and [Grassy Waters].” This appears to be a misstatement. The Applicants’ combined ROW is only 320 feet wide. Going east from the limits of construction, it is 160 feet to Grassy Waters. The Project’s buffer is 160 feet wide. The District accounted for secondary impacts to wetland dependent species, including snail kites, from noise and lights that might discourage use of the area. The Project would provide a tree buffer that will reduce noise and light impacts to Grassy Waters. The roadway lighting plan is also intended to reduce light penetration into Grassy Waters. Most of the threatened and endangered bird species are tolerant of roadways for foraging and roosting, but not for nesting. Section 10.2.7 requires the Applicants to provide reasonable assurances that any future phase of a project or project-related activities will not result in adverse impacts to the functions of wetlands or water quality violations. The Applicants satisfied this requirement by releasing of FDOT ROW north and south of the Project. Cumulative Impacts An applicant must provide reasonable assurance that a regulated activity will not cause unacceptable cumulative impacts upon wetlands and other surface waters within the same drainage basin as the regulated activity for which a permit is sought. Some of the proposed mitigation for the Project is out- of-basin. If an applicant proposes to mitigate impacts in another drainage basin, District rules require consideration of factors such as “connectivity of waters, hydrology, habitat range of affected species, and water quality” to determine whether there are unacceptable cumulative impacts. The Project is located in the eastern Palm Beach County Basin, which has approximately 21,000 acres of wetlands. About 89 percent of the wetlands in the basin are publicly-owned conservation lands, which means their wetland functions will continue into the future. The cumulative impact analysis was conservative, meaning that the actual impacts are likely to be fewer. Petitioner contends that Respondents’ cumulative impact analysis did not account for the unique nature of the Grassy Waters ecosystem as the only remaining low nutrient oligotrophic wetland in the region. The preponderance of the evidence shows that the historical wetland types in the Project area were not all like the open marsh found in the central and eastern portion of Grassy Waters. Respondents accounted for the loss of open water marsh that would be caused by the Project. On-Site Mitigation There would be 52.4 acres of on-site mitigation within a 160-foot-wide strip of land along the eastern limits of proposed construction. This area of the ROW would be managed by removing or treating the exotic vegetation, such as Brazilian Pepper and Maleleuca. Removing the exotic vegetation seed source would prevent further spread of these nuisance species into Grassy Waters. Where native habitats have been altered with ditches and berms, the land would be graded to create a slope from the limits of construction eastward to the edge of the ROW. The eastern elevation would be similar to the adjacent marsh or hydric pine areas of Grassy Waters. Then, native vegetation would be planted. The habitats enhanced, restored, or created would include freshwater marsh, hydric pine flatwoods and mixed forested wetlands, including cypress. The planting of mixed, forested species would provide sound and light buffering for snail kites and other species in Grassy Waters. Two wildlife passages would be created underneath the Project with fencing designed to direct wildlife to use the wildlife passages. Slats would be placed in the roadway fencing to prevent small animals from going through the fence and onto the roadway. The on-site mitigation was scored using UMAM and determined to result in functional gain. The UMAM analysis was conservative, meaning that the actual functional gain is likely to be greater. The City did not contest the UMAM scoring. Off-site Mitigation FDOT is applying mitigation credits from 210 acres at the Pine Glades Natural Area (“Pine Glades”) to offset impacts to 15.7 acres of herbaceous marsh and 26.78 acres of forested wetland impacts. Pine Glades is a regional off-site mitigation area located in the Loxahatchee River Basin and is owned and operated by Palm Beach County. Pine Glades consists of a mix of wet prairie, depression marshes, hydric pine flatwoods, and mesic flatwoods. The restoration work in Pine Glades has already been completed. Pines Glades implements a detailed management plan that provides regional ecological value. Robbins testified that Pine Glades has similar habitats to Grassy Waters. Pine Glades has periphyton, apple snails, snail kites, wood storks, and sand hill cranes. Pine Glades has some areas with oligotrophic conditions. Additional off-site mitigation to offset 52 acres of wetland impacts caused by the Project would be provided at the DuPuis Reserve (“DuPuis”). DuPuis is a regional off-site mitigation area located between the L-8 Canal and the C-44 Canal in western Palm Beach and Martin Counties, and is owned and operated by the District. DuPuis would provide mitigation with 34.71 acres of herbaceous wetlands and 43.8 acres of forested wetlands. DuPuis is appropriate to offset the impacts associated with the Project because it provides similar habitats with similar values of functions for similar wildlife. DuPuis implements a detailed management plan that provides regional ecological value. The City argues that there is little similarity between the Grassy Waters ecosystem and Pine Glades or DuPuis, so the mitigation there cannot offset the unique assemblage of plants and animals that would be lost in Grassy Waters. It is unnecessary for Pine Glades and DuPuis to be dominated by open water marshes like Grassy Waters. It is only necessary that they have some of these areas to offset Project impacts to open water marsh. Proposed snail kite mitigation would provide 52.5 more acres of snail kite habitat than would be directly impacted by the Project. The mitigation for snail kites will be located in FDOT ROW adjacent to the Project, south of the M-Canal, and north of Northlake Blvd. Erwin expressed concern about fragmentation of the ecosystems that would be caused by the Project. The areas that would be affected by the Project have already been fragmented by berms, ditches, and fences. Grassy Waters is surrounded by berms, a canal, and highways. The Project would cause fragmentation, like all roads. However, the fragmentation was reduced where practicable, and the City did not show that the roadway would cause the loss of any significant “greenway” now used by wildlife. Snail Kite Impacts Section 10.2.2(a) requires an applicant to provide reasonable assurances that a proposed activity would not impact wetlands and other surface waters so as to reduce the abundance and diversity of listed species. Snail kites, wood storks, sandhill cranes, white ibises, and little blue herons are listed species that have been observed within the Project corridor. As explained in the Conclusions of Law, the UMAM process is designed to mitigate for wetland functional losses, not snail kite functional losses. However, the potential impact to any listed species warrants close attention to the issue of whether function-for-function wetland mitigation would be provided. There will be 11.5 acres of direct impacts to snail kite habitat within the footprint of the Project area. Dr. Welch believes secondary impacts to wetland functions associated with snail kites could extend 800 feet east of the ROW. Mitigation for snail kites would be located in the Rangeline corridor south of the M-Canal and north of Northlake Boulevard. Dr. Welch estimated there were about 64 acres of snail kite habitat in the Rangeline corridor similar to the 11.5 acres of habitat located in the Project footprint. Dr. Welch conceded that he has no evidence that snail kites currently use the Rangeline, but he believes the habitat is suitable and is appropriate mitigation. Petitioner claims there are studies of “similar birds” indicating that snail kites avoid highways due to noise. However, the studies were not of similar birds. More weight is given to Dr. Welch’s testimony that snail kites are not particularly sensitive to roadway noise. Dr. Welch stated that Pine Glades would likely have value for snail kites because it is near the Hungryland Wildlife Management Area, which has the same number of successful snail kite nests as Grassy Waters. The City contends that Pine Glades is too far away from Grassy Waters to mitigate Project impacts to snail kites. However, snail kites range long distances to forage; several hundred miles in a few days. Satellite telemetry of snail kites shows snail kites from Grassy Waters are using Pine Glades for feeding. Dr. Welch reviewed snail kite nesting data to determine whether roads deterred nesting and found that snail kites frequently nested within 500 feet of major roadways. Dr. Welch refuted the idea that Grassy Waters provided snail kite refuge during drought conditions, because Grassy Waters is also subject to drought conditions that adversely affect snail kites. There are conditions in the permit to limit potential impacts to snail kites during construction of the Project. If snail kite nesting is observed within 1,640 feet of construction, all Project construction must cease. Thereafter, monitoring of the nest and notification of the U.S. Fish and Wildlife Service is required. Construction cannot resume until that nest has been considered finished. FDOT would place a conservation easement over 82.6 acres in the FDOT ROW between Okeechobee Boulevard and the M-Canal, south of the Project area that is the subject of this proceeding. The conservation easement would maintain connectivity between the Pond Cypress Natural Area and Grassy Waters and ensure that no future southern extension of the roadway will be constructed. A conservation easement would be placed on the FDOT ROW between Northlake Boulevard and SR 710, an area of approximately 43.5 acres. Preserving this area protects a hydrologic connection between Loxahatchee Slough Natural Area and Grassy Waters. It also ensures no future northern extension of the roadway. A conservation easement would be placed on a portion of the FDOT ROW between SR 710 and Jupiter Farms, an area of 44.5 acres. This section of ROW is in the Loxahatchee Slough and the release of the ROW would be a direct benefit to Loxahatchee Slough. The preservation of these areas would benefit fishing and recreational values in the Pond Cypress Natural Area, Grassy Waters, and the Loxahatchee Slough Natural Area. These conservation areas did not receive UMAM credits to reduce the wetland acreage needed to offset wetland functional losses, but they were included in the mitigation credit for benefits to snail kites and other wildlife. Summary The preponderance of the evidence established that the proposed mitigation offsets the impacts to wetlands and other surface waters that would be caused by the Project and exceeds the requirements of District rules. Practicable Design Modifications District rules require an applicant to consider alternatives that would avoid or reduce wetland impacts. The City claims the Applicants failed to comply with this rule because FDOT selected a roadway corridor that was expected to have greater environmental impacts than some of the other three corridors that were being considered. As explained in the Conclusions of Law, this argument is misplaced. The District’s review of the Applicants’ measures to avoid or minimize wetland impacts was appropriately confined to Corridor 3, the corridor selected by FDOT where the Project is proposed. The Applicants reduced and eliminated impacts of the Project in several ways. For example, the footprint of the road was narrowed from six lanes to four lanes, wildlife underpasses were provided, retaining walls were used to narrow stormwater features, the median was reduced in size, and the design speed limit was reduced for the bridge at the M-Canal crossing. Under two circumstances, District rules allow an applicant to avoid the requirement to implement practicable design modifications to reduce or eliminate wetland impacts, which are referred to as the “opt-out” provisions. Section 10.2.1.2, Volume I, of the Applicant’s Handbook (“A.H.”) provides: The ecological value of the functions provided by the area of wetland or other surface water to be adversely affected is low, based on a site specific analysis using the factors in section 10.2.2.3, below, and the proposed mitigation will provide greater long term ecological value than the area of wetland or other surface water to be adversely affected, or The applicant proposes mitigation that implements all or part of a plan that provides regional ecological value and that provides greater long term ecological value than the area of wetland or other surface water to be adversely affected. The District determined that the Applicants meet both tests. The preponderance of the evidence supports the District’s determination. The ecological value of the functions provided by the affected wetlands and surface is low and the proposed mitigation would provide greater long-term ecological value than the area being impacted. Pine Glades and DuPuis are part of a plan to restore the ecological value of Northern Palm Beach County and create an “ocean to lake” system of preserves and natural areas.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the South Florida Water Management District enter a final order approving Permit Number 50-05422-P on the terms and conditions set forth in the amended Staff Report, and the complete application for the Permit. DONE AND ENTERED this 31st day of March, 2017, in Tallahassee, Leon County, Florida. S BRAM D. E. CANTER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 31st day of March, 2017.
Findings Of Fact On November 1, 1982, Respondent Janson filed a Joint Application for a dredge and fill permit from Respondent, Department of Environmental Regulation, and from the Department of the Army Corps of Engineers. The project described in that application involved the construction of an approximately 1,000-square- foot, pile-supported residence, landward of the mean high water line but within the landward extent of Robinson Creek in St. Johns County, Florida. The proposed project also involved the placement of approximately 35 cubic yards of fill and a 30-foot culvert within a small (approximately 4-foot), tidally- influenced roadside ditch for driveway access and parking. The original application sought permission to place part of a concrete driveway and tool shed within the landward extent of Robinson Creek. The project is to be constructed on Lot 47, J.A. Lew Subdivision. Respondent Janson owns Lot 47, as well as Lots 45 and 46, which lots are north of and adjoining Lot 47 and also adjoining Robinson Creek. The next adjoining property owner to the north is the City of St. Augustine, Florida, which presumably owns the street. The adjoining property owner to the south of Lot 47 is Virginia P. Melichar. Neither Melichar nor the City objected to the Department's approval of the dredge and fill permit application. In support of his application, Janson retained the services of a registered surveyor and civil engineer, who performed a survey on Lot 47 to determine the location of the mean high water line with reference to the proposed project. That expert determined the location of the mean high water line to be at elevation 2.4 feet. Accordingly, all work contemplated by the dredge and fill permit is upland from the mean high water line. T.J. Deuerling, an environmental specialist for Respondent, Department of Environmental Regulation, visited the project site on December 13, 1982 and on December 30, 1982 in order to prepare the Department's Biological and Water Quality Assessment. As a result of those site visits, Deuerling recommended to Respondent Janson that he modify his permit application by moving the concrete slab and tool shed from the marsh area onto the uplands. Janson did so revise his application. In spite of the name of the permit being sought by Respondent Janson, the project involves no dredging. However, the culvert and its attendant fill would be placed in the man-made roadside ditch. That ditch constitutes a very weak transitional marsh. Although the culvert will eliminate some vegetation within that ditch, the effect of the elimination will be insignificant on water quality. The pilings for the pile-supported residence will also eliminate a small area of marsh. The anticipated shading caused by the pile-supported residence may impact somewhat on the vegetation in a small area below the residence; however, due to the fact that the floor of the house will be eight feet above the ground, light will still be able to penetrate. Therefore, the vegetation below the pile-supported residence will continue to act as a filter for pollutants. Janson has mitigated the small loss in wetlands by modifying his project so as to remove the concrete slab and tool shed from the marsh area to the uplands. Due to the project's small size, no storm water impact can be expected. Additionally, no evidence was introduced to show a violation of any water quality standard as a result of the proposed project. On March 16, 1983, Respondent, Department of Environmental Regulation, executed its Intent to Issue the dredge and fill permit in accordance with the revised application and subject to the conditions that: (1) turbidity curtains be employed in the ditch during the placement of fill over the culvert to contain any turbidity generated, and (2) construction on the uplands be confined to periods of normal water level conditions. On July 5, 1983, the Department of the Army Corps of Engineers issued its Permit and Notice of Authorization. The essence of the testimony presented by the Petitioners, including that of the employees of the St. Johns River Water Management District, who testified in opposition to the proposed project, is that even though Janson's proposed project would not impact water quality in a way that was either significant or measurable (although no one even suggested any specific water quality standard that might be violated), approval of Janson's permit might set a precedent for other projects which might then have a cumulative impact in some unspecified way at some unspecified location. No evidence was offered to show that Respondent, Department of Environmental Regulation's review of permit applications is other than site specific. Further, no evidence was introduced to show any proposed project anywhere having any impact with which Janson's project could be cumulative. Petitioners Sandquist and Shuler live in the neighborhood of the proposed project, perhaps as close as two blocks away.

Findings Of Fact Petitioner owns property adjacent to Sims Creek located in Palm Beach County, Florida. Petitioner is undertaking a development on the property. The development was initiated by the Great American Anvil Corporation, the previous owner of the property. The development as originally conceived included construction of a dock in Sims Creek. The Great American Anvil Corporation applied for a permit to the State Board of Trustees of the Internal Improvement Trust Fund. On February 5, 1975, a permit was issued to allow Great American Anvil Corporation "to construct eight (8) finger piers each twenty feet long by two feet wide, and three triangular piers twenty feet long by five feet wide at the base and two feet wide at the top" in Sims Creek. The permit was issued for construction of the docking facility and by its terms expired on a specified date. The permit was never assigned or transferred to Petitioner. The permit has expired, and is no longer effective. A bulkhead has already been constructed along Petitioner's property. Petitioner is seeking a permit which would authorize it to construct a perimeter dock which would run along the approximately three hundred foot border of Petitioner's property and Sims Creek, and extend four feet over Sims Creek. Petitioner is also seeking to construct ten piers out from the perimeter dock, each of which would be twenty-five feet long and two feet wide. Mooring spaces would be provided for sixteen or more boats The perimeter dock and the ten piers would be supported by pilings which would be placed in the creek bottom. The permit application provides that the pilings would be installed by a process called "jetting". Sims Creek is a natural, navigable tributary of the Loxahatchee River. The mouth of Sims Creek on the Loxahatchee River is located in fairly close proximity to where a canal known as the "C-18 Canal" empties into the river. Sims Creek is a winding stream which has been relatively undisturbed by development. Petitioner's project is located approximately one thousand to fourteen hundred linear feet upland from the mouth of the creek. Approximately five hundred feet upland from the proposed docks, the creek veers sharply to the south and becomes significantly more shallow. The creek is influenced by both estuarine and tidal flows. During high tides, water flows from the Loxahatchee River upland into the creek. During low tides the water flows out of the creek into the Loxahatchee River. In addition, water generally drains through the creek into the river. The creek has good flushing characteristics. The "residence time" for water in the creek is typically one day, except in isolated pockets along the shoreline, and in deeper basins which occur in the creek. The area of the creek where the proposed docks would be constructed is a basin area. Waters reach a depth of eight feet. This area of the creek is stressed in water quality terms. Dissolved oxygen values measured at the site are in excess of Department standards. This is the result of the depth at the location; the oozy, organic bottom soils; and the fact that a storm water outfall and a sewage outfall enter the creek on the opposite side from Petitioner's property. The creek is generally more shallow than in this basin area. Near to the mouth of the creek, water depths are as shallow as 2.25 feet during high tide. The deepest continuous channel from the proposed docks to the mouth of the river is approximately three feet at high tide, and from one to one and one-half feet at low tide. The shallower areas of the creek are characterized by sandy bottoms, good water quality, and a rather high level of plant and animal activity which is diverse. Shorelines along most of the creek are dominated by mangrove vegetation. There is presently a limited amount of boating activity that occurs in the creek. Persons who testified at the hearing witnessed at various times from one to seven small motor craft in the creek. Construction of the perimeter dock and piers in the manner proposed by Petitioner in its application would have significant adverse short term water quality impacts. The "jetting process" for installing pilings would result in considerable turbidity which would be likely to violate state standards within the area of construction, and downstream to the mouth of the creek. These short term adverse impacts could be alleviated by installing the pilings through a "driving technique" and by use of turbidity screens. Petitioner has expressed a willingness to utilize these construction techniques. The proposed docking facility is likely to have an adverse impact upon water quality in Sims Creek. The project, if completed, is likely to cause violations of the Department's water quality standards. Dissolved oxygen levels in the area of the proposed project already exceed the Department's standards. The Petitioner's proposed docks would cover a significant portion of the water surface with docks, and this would exacerbate dissolved oxygen levels. Furthermore, increased boating activity in the area would, due to the interjection of greases and oils, further adversely impact dissolved oxygen levels, and can reasonably be expected to lead to violations of the Department's standards for biologic oxygen demand and oils and greases. Petitioner's proposed docking facility includes mooring spaces for approximately sixteen boats. The dock would serve therefore to increase boating activity in Sims Creek by three times or more Sims Creek is difficult to navigate without disturbing the productive shallow bottom areas. Increased boating activity is likely to disturb these areas and to lead to the destruction of a natural marine habitat. Sims Creek is too shallow a water body to sustain the sort of boating traffic that would be generated through construction of a docking facility such as Petitioner has proposed. Sims Creek is sovereignty land of the State of Florida. Petitioner has not received approval from the Board of Trustees of the Internal Improvement Trust Fund or the Department of Natural Resources to use Sims Creek in the manner proposed.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, hereby, RECOMMENDED: That a final order be entered by the Department of Environmental Regulation denying the application submitted by Landin Ltd, for a dredge and fill permit to construct a docking facility in Sims Creek, West Palm Beach, Florida. RECOMMENDED this 5th day of April, 1982, in Tallahassee, Florida. G.

The Issue The issue in this case is whether, and what, reasonable mitigative conditions are necessary to protect the interest of the public and the environment, prior to issuing Petitioner's default permit.
Findings Of Fact Application and Default Petitioner's application is to dredge an extension, 50 feet wide by 300 feet long by 5 feet deep, to an existing 650 foot-long man-made canal of the same width and depth, normal (perpendicular) to old Central and South Florida Flood Control (now SFWMD) Rim Canal (the L-48 Borrow Canal), which is along the northwest shore of Lake Okeechobee. Petitioner's initial, incomplete application filed in DEP's Port St. Lucie office on August 31, 2000, included: the proposed project's location by County, section, township, and range; its legal description; a sketch of its general location and surrounding landmarks; a SFWMD letter verifying conformity with the requirements of a "No Notice General Permit for Activities in Uplands" of a drawing for a proposed pond expansion (to a size less than half an acre), "which will provide borrow material necessary for a house pad and access drive"; a description of water control Structure 127, together with its purpose, operation, and flood discharge characteristics, which were said to describe water levels in Buckhead Ridge, the name of the subdivision where the project was proposed; two virtually identical copies of a boundary survey for Petitioner's property (one with legal description circled) showing the existing canal, with boat basin off the canal on Petitioner's property near the L-48 Rim Canal, at a scale of one inch equals 200 feet; two more virtually identical copies of the boundary survey at the same scale showing the existing canal, with boat basin off the canal on Petitioner's property near the L-48 Rim Canal, and the proposed canal extension and house locations; and a copy of a 1996 aerial photograph of Petitioner's property and existing canal, and vicinity. The application did not describe a proposed method or any other details of construction, include any water quality information, or include a water quality monitoring plan. On September 15, 2000, Petitioner filed an additional page of the application form with DEP's Punta Gorda office. The page added the information: "Digging to be done with trac-hoe." No other specifics of the proposed construction method were included. What happened after the filing of the application is described in Tuten I and Tuten II, which are the law of the case. However, those opinions do not explain the delay between Tuten I and the issuance of DEP's proposed ERP with conditions approximately two years later. The evidence presented at the final hearing explained only that counsel of record for DEP promptly asked district staff to draft a proposed default ERP with conditions that "would probably track the RAI that had been sent out prior to the default." DEP's district staff promptly complied and forwarded the draft to DEP's Office of General Counsel in Tallahassee, which did not provide any legal advice as to the draft ERP for almost two years. There was no further explanation for the delay. As reflected in Tuten II and in the Preliminary Statement, it was DEP's position that the proper procedure to follow after its default was to issue a proposed ERP with conditions and that it would be Petitioner's burden to request an administrative hearing to contest any conditions and to prove Petitioner's entitlement to a default ERP with conditions other than those in DEP's proposed ERP. DEP's Proposed General Conditions The conditions DEP wants attached to Petitioner's default permit include general conditions taken from SFWMD's Rule 40E-4.381, which are appropriate, as indicated in the Preliminary Statement and Conclusions of Law, and as conceded by Petitioner's expert. While the Rule 40E-4.381 general conditions are appropriate, Petitioner takes the position (and his expert testified) that some of the general permit conditions contained in Rule 62-4.160, as well as Rule 62-4.070(7) (providing that "issuance of a permit does not relieve any person from complying with the requirements of Chapter 403, F.S., or Department rules"), are more appropriate general conditions to attach to Petitioner's default ERP, even if technically inapplicable, because the Chapter 62 Rules govern the operation of a permitted project (whereas the former govern the construction of a permitted project) and are "more protective of the environment." Actually, all of the rules contain general conditions that govern both construction and operation phases of an ERP, and all are "protective of the environment." There is no reason to add general conditions taken from Rules 62-4.160 and 62-4.070(7) to the applicable general conditions contained in Rule 40E-4.381. DEP's Proposed Specific Conditions (i) In General The conditions DEP wants attached to Petitioner's default permit also include specific conditions which essentially require that Petitioner provide the information in the RAI sent in December 2000, together with additional specific conditions thought necessary to protect the environment in light of the lack of detail in the application without the answers to the RAI. Some DEP's proposed specific conditions are designed to ascertain whether the application would provide reasonable assurance that permitting criteria would be met. (They make the requested information subject to DEP "approval" based on whether reasonable assurance is provided.) In general, those specific conditions no longer are appropriate since DEP is required to issue a default permit. (Looked at another way, inclusion of those specific conditions effectively would un-do the default, in direct contradiction of the court's opinion Tuten I and Tuten II.) See Conclusion of Law 52, infra. On the other hand, some of the RAI information was designed to ascertain the proposed method and other details of construction. Pending the "answers" to those "RAI conditions," DEP also wants broad specific conditions, including a baseline water quality investigation and a water quality monitoring plan, designed to be adequate for a "worst case scenario" that could result from the project. Petitioner opposes DEP's proposed broad specific conditions. He takes the position that it was incumbent on DEP in this proceeding to use discovery procedures to ascertain Petitioner's intended method of construction and tailor specific conditions to the method of construction revealed through discovery. At the same time, Petitioner opposes DEP's proposed specific conditions requiring RAI-type information, including the details of his proposed construction method. Notwithstanding the positions Petitioner has taken in this case, his expert testified that Petitioner intends to use a steel wall inserted between the water and upland at the end of the existing canal, phased excavation from the upland side, and removal of the steel wall in the final phase of construction. Assuming that method of construction, Petitioner takes the position (and his expert testified) that the statutes, rules, and permit conditions acceptable to Petitioner, and which generally prohibit pollution of the environment, are adequate. Even if the statutes, rules, and permit conditions acceptable to Petitioner would be adequate for the method of construction Petitioner now says he will use, Petitioner's application does not in fact commit to a method of construction. All Petitioner's application says is that he intends to dig with a trac-hoe. Without a binding commitment to a method of construction, it was appropriate for DEP to take the position that specific conditions were necessary to ascertain the method of construction Petitioner would use and, pending the "answers" to those "RAI conditions," and to impose broad specific conditions, including a baseline water quality investigation and a water quality monitoring plan, designed to be adequate for a "worst case scenario" that could result from the project. In his PRO, Petitioner committed to use the construction method described by his expert during the hearing, as follows: Excavation of any spoil shall be done by means of a mechanical trac-hoe; Prior to the excavation of any soil, Petitioner shall first install an isolating wall, such as interlocking sheet pile, between the existing man-made canal, and the proposed canal extension; The mechanical excavation shall be done in such a manner such that the excavated soil is not deposited in wetlands or in areas where it might be reasonably contemplated to re-enter the waters of the State of Florida; After the proposed canal extension is excavated to its project limits in the foregoing manner, the side slopes of the canal extension shall be allowed to revegetate prior to removal of the isolating wall. With a condition imposing this method of construction, fewer and narrower specific conditions will be necessary. ii. Seriatim Discussion DEP's proposed Specific Condition 1 requires a perpetual conservation easement prohibiting docking and mooring of water craft on all portions of Petitioner's property within the canal extension in order to "address cumulative impacts." But DEP did not prove that the proposed conservation easement was reasonably necessary to protect the interest of the public and the environment. First, DEP did not prove that there would be any cumulative impacts, much less unacceptable cumulative impacts, from Petitioner's project. See § 373.414(8), Fla. Stat.; Rule 40E-4.302(1)(b); and BOR § 4.2.8. Second, even if unacceptable cumulative impacts were proven, those could be addressed in other permit cases (assuming no DEP default in those proceedings), since the concept of cumulative impacts essentially requires an applicant to share acceptable cumulative impacts with other similar permittees, applicants, and foreseeable future applicants. See Broward County v. Weiss, et al., DOAH Case No. 01-3373, 2002 Fla. ENV LEXIS 298, at ¶¶54-58 (DOAH Aug. 27, 2002). As Petitioner points out, the easement further described in Specific Condition 1 appears to be overly broad for its stated purpose in that it would cover "the legal description of the entire property affected by this permit and shown on the attached project drawings," which could be interpreted to include not just the canal extension but the entire extended canal, or even the entirety of Petitioner's 6.6 acres of property. Indeed, the latter might have been the actual intention, since DEP's witness testified that Specific Condition 1 also was intended to address impacts from fertilizer runoff and septic tank leaching from new homes built along the canal. Although some of those impacts (as well as future construction of additional homes and docks) actually are secondary impacts, not cumulative impacts, it is possible that they can be addressed in DEP or SFWMD proceedings on future applications, as well as in Department of Health proceedings on septic tank installations. DEP's proposed Specific Condition 2 requires that: spoil material from the dredging to be "used for the sole purpose of constructing a single-family fill pad" on Petitioner's property under a pending permit; spoil "be placed in a manner so as not to affect wetlands or other surface waters"; and the "spoil disposal location shall be shown in the drawings required by Specific Condition #4 below." DEP did not prove that the first requirement was reasonably necessary to protect the interest of the public and the environment. First, it is unreasonable since Petitioner already has built the referenced single-family fill pad and a home on top of it. Second, the reason DEP's witness gave for this requirement was that, under an operating agreement with SFWMD (which was officially recognized), DEP only has jurisdiction to take action on single-family uses (which he defined to include duplexes, triplexes, and quadriplexes) but not on larger multi-family and certain other projects. However, the operating agreement on jurisdiction is not a reason to place Specific Condition 1 on the use of spoil material on Petitioner's default permit. SFWMD can regulate, in permitting proceedings under its jurisdiction, the placement of fill material for multi- family construction or other projects not under DEP jurisdiction. In addition, under the operating agreement, jurisdiction can be "swapped" by written agreement in cases where deviation from the operating agreement would result in more efficient and effective regulation. The second two requirements under Specific Condition 2 are reasonable and necessary to protect the interest of the public and the environment. DEP's proposed Specific Condition 3 requires disclosure of all pending and issued permits for the property from SFWMD, Glades County, or the U.S. Army Corps of Engineers (USCOE). DEP did not prove that this is reasonable or reasonably necessary to protect the interest of the public and the environment. DEP probably has all such permits and can easily obtain any it does not have. DEP's proposed Specific Condition 4 requires fully dimensional plan view and cross-sectional drawings of the property and area to be dredged, before and after dredging, including a north arrow and the water depths in and adjacent to the dredge area. DEP's witness stated that the primary purpose of this part of the condition is to provide hydrographic information normally provided in an application (or required in an RAI) so that DEP's hydrographic engineer can ascertain flushing characteristics, which are pertinent primarily to the dissolved oxygen water quality parameter and to heavy metals from boat use. As previously indicated, requests for information relating to reasonable assurance and the public interest test generally no longer are appropriate since DEP is required to issue a default permit. See Finding 9, supra. However, information regarding flushing characteristics, combined with other specific conditions, is reasonable and necessary to protect the interest of the public and the environment. See Finding 27, infra. In addition, the plan view and cross-sectional drawings required by Specific Condition 4 are to include the location of navigational obstructions in the immediate area, any roads, ditches, or utility lines that abut the property; any encumbrances, and any associated structures. DEP's witness stated that the primary purpose of this information is to determine whether Petitioner has provided reasonable assurance that the "public interest" test under Rule 40E-4.302 is met, and make sure that management, placement, and disposal of spoil material do not infringe on property rights or block culverts and cause flooding. As previously indicated, requests for information relating to reasonable assurance and the public interest test generally no longer are appropriate. See Finding 9, supra. However, information regarding the location of culverts to assure that management of spoil does not cause flooding is reasonable and necessary to protect the interest of the public and the environment. In addition to objecting to having to provide RAI information as a "default permittee," Petitioner's expert asserted that the information requested in Specific Condition 4 would be provided as part of the "as-built" drawings required by General Condition 6. But General Condition 6 does not require "as-built" drawings. Rather, it requires an "as-built" certification that can be based on "as-built" drawings or on-site observation. Besides, the purpose of the "as-built" certification is to determine "if the work was completed in compliance with permitted plans and specifications." Without the information requested in Specific Condition 4, there would only be vague and general permitted plans and specifications and hydrographic information. Finally as to Specific Condition 4, Petitioner objects to the requirement that the drawings be sealed by a registered professional engineer. However, Petitioner cites to General Condition 6, which requires that the "as-built" certification be given by a "registered professional" and cites Rule Form 62- 343.900(5), which makes it clear that "registered professional" in that context means a registered professional engineer. DEP's proposed Specific Condition 5 requires Petitioner to submit for DEP approval, within 180 days of permit issuance and before any construction, reasonable assurance that the canal extension will not violate water quality standards due to depth or configuration; that it will not cause a violation of water quality standards in receiving water bodies; and that it will be configured to prevent creation of debris traps or stagnant areas that could result in water quality violations. The reasonable assurance is to include hydrographic information or studies to document flushing time and an evaluation of the maximum desirable flushing time, taking several pertinent factors into consideration. As previously indicated, requests for information relating to reasonable assurance and the public interest test generally no longer are appropriate. See Finding 9, supra. In addition, Petitioner's expert testified without dispute that the information requested could take more than 180 days and cost approximately $20,000. However, it is reasonable and necessary to protect the interest of the public and the environment to include a specific condition that Petitioner's canal extension be configured so as have the best practicable flushing characteristics. DEP's proposed Specific Condition 6 requires Petitioner to submit for DEP approval, within 180 days of permit issuance and before any construction, reasonable assurance that construction of the canal extension will meet all permit criteria set out in Rules 40E-4.301 and 40E-4.302 and in BOR § 4.1.1. As previously indicated, requests for information relating to reasonable assurance and the public interest test generally no longer are appropriate. See Finding 9, supra. DEP's proposed Specific Condition 7 requires Petitioner to submit existing water quality information for DEP approval within 180 days of permit issuance and before any construction. In this instance, DEP's approval would not be a determination on the provision of reasonable assurance but a determination as to the reliability of the water quality information, which is necessary to establish a baseline for assessing and monitoring the impact of the project. For that reason, the information is reasonable and necessary to protect the interest of the public and the environment. Petitioner's expert testified that the information could cost $2,000-$3,000 to produce (and more, if DEP rejects the information submitted, and more information is required). He also testified that water quality information already is available, including over 25 years worth of at least monthly information on all pertinent parameters except biological oxygen demand and fecal coliform, at a SFWMD monitoring station in the Rim Canal at Structure 127 (a lock and pump station at the Hoover Levee on Lake Okeechobee) approximately 8,000 feet away from Petitioner's canal. DEP did not prove that the SFWMD information would not serve the purpose of establishing baseline water quality for Petitioner's canal for all but the missing parameters. For that reason, only water quality information for the missing parameters is reasonable and necessary to protect the interest of the public and the environment in this case. DEP's proposed Specific Condition 8 requires that, if the water quality information required by Specific Condition 7 shows any violations of state ambient water quality standards, Petitioner must submit for DEP approval, within 180 days of permit issuance and before any construction, a plan to achieve net improvement for any parameters shown to be in violation, as required by Section 373.414, Florida Statutes. See also BOR § and 4.2.4.2. Normally, if applicable, this information would be expected in an application or RAI response. Petitioner's expert testified that this condition would require Petitioner to help "fix Buckhead Ridge" (unfairly) and that it would cost lots of money. But Petitioner did not dispute that the law requires a plan for a "net improvement," which does not necessarily require a complete "fix" of water quality violations, if any. As previously indicated, requests for information relating to reasonable assurance and the public interest test generally no longer are appropriate, and Petitioner's ability to construct the canal extension should not be dependent on DEP's approval of a net improvement plan. See Finding 9, supra. But a specific condition that Petitioner implement a plan to achieve net water quality improvement in the event of any water quality violations would be reasonable and necessary to protect the interest of the public and the environment. DEP's proposed Specific Condition 9 requires Petitioner to submit for DEP's approval, at least 60 days before construction, detailed information on how Petitioner intends to prevent sediments and contaminants from being released into jurisdictional waters. DEP asserts that this specific condition asks for a detailed description of how the applicant will comply with various subsections of BOR § 4.2.4.1 that address short-term water quality to aid in providing reasonable assurance that water quality standards will not be violated, as required by Section 373.414(1), Florida Statutes, and Rule 40E-4.301(1)(e). As previously indicated, requests for information relating to reasonable assurance and the public interest test generally no longer are appropriate, and Petitioner's ability to construct the canal extension should not be dependent on DEP's approval of information submitted. See Finding 9, supra. But it is reasonable and necessary to protect the interest of the public and the environment to include a specific condition that Petitioner's canal extension be constructed using adequate turbidity barriers; stabilize newly created slopes or surfaces in or adjacent to wetlands and other surface waters to prevent erosion and turbidity; avoid propeller dredging and rutting from vehicular traffic; maintain construction equipment to ensure that oils, greases, gasoline, or other pollutants are not released into wetlands and other surface waters; and prevent any other discharges during construction that will cause water quality violations. DEP's proposed Specific Condition 10 requires Petitioner to submit, at least 60 days before construction, detailed information regarding Petitioner's plans for handling spoil from dredging, including "discharge details, locations retention plans, volumes, and data used to size the disposal cell(s)." It allows this information to be combined with the Specific Condition 2 submittal. It also requires spoil to be properly contained to prevent return of spoil to waters of the State and to be deposited in a self-contained upland site that prevents return of any water or material into waters of the State. DEP asserts that this specific condition (like Specific Condition 9) is necessary to comply with BOR § 4.2.4.1 by addressing short-term water quality to aid in providing reasonable assurance that water quality standards will not be violated, as required by Section 373.414(1), Florida Statutes, and Rule 40E-4.301(1)(e). As previously indicated, requests for information relating to reasonable assurance and the public interest test generally no longer are appropriate, and Petitioner's ability to construct the canal extension should not be dependent on DEP's approval of information submitted. See Finding 9, supra. But it is reasonable and necessary to protect the interest of the public and the environment to include a specific condition requiring spoil to be properly contained to prevent return of spoil to waters of the State and to be deposited in a self-contained upland site that prevents return of any water or material into waters of the State. DEP's proposed Specific Condition 11 requires Petitioner to submit "as-built" drawings to DEP's Punta Gorda office with 30 days after completion of construction, "as required by General Condition #6." Petitioner's expert testified that this condition was unreasonable only because it duplicates General Condition 6 and two statutes. But General Condition 6 actually does not require "as-built" drawings, see Finding 9, supra, and it is not clear what statutes Petitioner's expert was referring to. For these reasons, and because it provides a filing location, Specific Condition 11 is reasonable and reasonably necessary to protect the interest of the public and the environment. DEP's proposed Specific Condition 12 requires Petitioner to "maintain the permitted canal free of all rafted debris by removal and property upland disposal." DEP asserts that this specific condition is necessary to comply with BOR § by addressing long-term water quality to aid in providing reasonable assurance that water quality standards will not be violated, as required by Section 373.414(1), Florida Statutes, and Rule 40E-4.301(1)(e). Rafted debris, which may be of an organic or inorganic nature, can accumulate at the end of canals due to wind, waves, boats, or other forces. Such organic rafted debris may rot and, by creating a high biological oxygen demand, rob the water of dissolved oxygen. Petitioner's only expressed opposition to this condition is that the conservation easement in Specific Condition 3 might prevent compliance. While it is unclear how the easement would prevent compliance, the issue is eliminated if no conservation easement is required. DEP's proposed Specific Condition 13 requires Petitioner to use turbidity screens during construction for compliance with BOR § 4.2.4.1 by addressing short-term water quality to aid in providing reasonable assurance that water quality standards will not be violated, as required by Section 373.414(1), Florida Statutes, and Rule 40E-4.301(1)(e). The turbidity screen requirements detailed in this specific condition are typical best management practices that contractors use and are a standard condition placed in permits of this nature by DEP. Petitioner contends that turbidity screens are unnecessary given his intended construction method and that other conditions are sufficient to cover DEP's concerns. However, as indicated, the application does not commit to a method of construction. With the application in its current state, Specific Condition 13 is appropriate subject to a demonstration by Petitioner that turbidity screens are not needed for the construction method committed to in Petitioner's PRO. DEP's proposed Specific Condition 14 requires Petitioner to "ensure that any discharge or release of pollutants during construction or alteration are not released into wetlands or other surface waters that will cause water quality standards to be violated." Again, this condition is intended to ensure compliance with BOR § 4.2.4.1 by addressing short-term water quality to aid in providing reasonable assurance that water quality standards will not be violated, as required by Section 373.414(1), Florida Statutes, and Rule 40E-4.301(1)(e). While this specific condition seems general and perhaps duplicates other conditions (which was Petitioner's only point of contention), DEP added it in an attempt to make sure the possible and not uncommon release of pollutants from construction equipment was addressed. As such, the condition is appropriate. DEP's proposed Specific Condition 15 provides details on the use of turbidity screens. Petitioner's primary points of contention are that turbidity screens are not needed for his intended construction method and that other conditions are sufficient without this condition. As such, the relevant issues already have been addressed in connection with Specific Condition With the application in its current state, Specific Condition 15 is appropriate subject to a demonstration by Petitioner that turbidity screens are not needed for the construction method committed to in Petitioner's PRO. DEP's proposed Specific Condition 16 requires Petitioner to used staked filter cloth to contain any turbid run- off and erosion from created slopes of the canal extension. This is the most common best management practice and is a standard condition for ERP permits dealing with side slopes that may affect water quality. Unstable slopes can result in chronic turbidity, which is detrimental to wildlife. Unstable slopes also can lead to upland runoff being deposited into the water along with debris and sediment. Such runoff can bring deleterious substances such as heavy metals and nutrient-loaded substances that might impact dissolved oxygen levels in the water. Petitioner's primary points of contention on Specific Condition 16 are that, like turbidity screens, staked filter cloth is not needed for Petitioner's intended construction method and that other conditions are sufficient without this condition. (Petitioner also questions why the condition gives Petitioner up to 72 hours from "attaining final grade" to stabilize side slopes, but the condition also requires side slope stabilization "as soon as possible," and the 72-hour outside limit seems reasonable.) As such, the relevant issues already have been addressed in connection with Specific Condition 13 and 15. With the application in its current state, Specific Condition 16 is appropriate subject to a demonstration by Petitioner that staked filter cloth is not needed if he uses the construction method committed to in Petitioner's PRO. DEP's proposed Specific Condition 17, 18, 19, and 20: details required long-term water quality monitoring and reporting [#17]; establishes sampling intervals and requires Petitioner to submit a "plan to remediate" if monitoring shows water quality violations or "a trend toward future violations of water quality standards directly related to the permitted canal" [#18]; allows "additional water quality treatment methods" to be required if water quality monitoring shows it to be necessary [#19]; and allows water quality monitoring requirements to be modified (which "may include reduction in frequency and parameters . . . or the release of the monitoring process"), "based on long term trends indicate that the permitted canal is not a source to create water quality violations [#20]." These conditions are intended to ensure compliance with BOR § 4.2.4.2 by addressing long-term water quality to aid in providing reasonable assurance that water quality standards will not be violated, as required by Section 373.414(1), Florida Statutes, and Rule 40E-4.301(1)(e). The evidence was that these specific conditions are standard for ERP permits where a constructed system may lead to water quality violations in the long term. Contrary to Petitioner's contentions, conditions of this kind are not dependent on a post-construction finding of water quality standard violations (even though DEP defaulted on Petitioner's application). Besides contending that monitoring requirements in Specific Conditions 17 and 18 are unnecessary, Petitioner also contends that they are too extensive and not tailored to Petitioner's intended construction, but DEP proved their necessity, even assuming the construction method committed to in Petitioner's PRO. Petitioner complains that Specific Condition 19 is vague and that Petitioner's ERP does not provide for "water quality treatment." But the present absence of post-construction water quality treatment should not preclude the possible future imposition of some kind of water quality treatment if monitoring shows it to be necessary. For this kind of condition, the absence of detail regarding the kind of treatment to be imposed is natural since it would depend on future events. DEP's proposed Specific Condition 21 merely requires that Petitioner's project comply with State water quality standards in Florida Administrative Code Rules 62-302.500 and 62- 302.530. Petitioner contends that this is duplicative and unnecessary. But it certainly is not unreasonable to be specific in this regard. No Improper Purpose As part of his request for attorney's fees under Section 120.595, Florida Statutes, Petitioner necessarily contends that DEP participated in this proceeding "for an improper purpose"--i.e., "primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of litigation, licensing, or securing the approval of an activity." Even assuming that DEP should be considered a "nonprevailing adverse party," Petitioner's evidence did not prove that DEP's participation was for an "improper purpose." To the contrary, DEP "participated" initially because Petitioner filed an application. DEP's denial of Petitioner's application was not proven to be "for an improper purpose" but rather for the purpose of attempting to protect the environment. The propriety of the denial was litigated in Tuten I, which made no finding that the denial was "for an improper purpose" and which ordered DEP to participate in a hearing for purposes of determining "reasonable mitigative conditions." The two-year delay between Tuten I and Tuten II was not fully explained, but Tuten II also made no finding that the denial, or the delay, or DEP's proposed ERP with conditions were "for an improper purpose" and again ordered DEP to participate in a hearing for purposes of determining "reasonable mitigative conditions." While DEP's views on the nature of the hearing to be conducted for purposes of determining "reasonable mitigative conditions" was rejected, it was not proven that DEP argued its views "for an improper purpose" or that its participation, once its views were rejected, was "for an improper purpose," as defined by statute. To the contrary, the evidence was that DEP participated in this proceeding in an attempt to place conditions on Petitioner's permit which DEP thought were necessary to protect the environment, many (although not all) of which are accepted in this Recommended Order. As Petitioner accepts and points out, it remains necessary for Petitioner to construct and operate his project in a manner that does not violate environmental statutes and rules. But without any water quality information or monitoring, DEP's enforcement of those laws and rules will be hamstrung.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that DEP enter a final order issuing Petitioner a default ERP, to expire five years from issuance, to dredge an extension, 50 feet wide by 300 feet long by 5 feet deep, to an existing man-made canal, as applied for, subject to: DEP's proposed General Conditions 1-19; DEP's proposed Specific Conditions 4 and 11-21; DEP's proposed Specific Conditions 2, 5, and 7-10, as modified by the Findings of Fact; and the construction method committed to in Petitioner's PRO (see Finding 14, supra.

Findings Of Fact Tim Youngquist is a licensed water well contractor, holding Florida license #2172, and is principal of Youngquist Brothers, Inc. The South Florida Water Management District, operating pursuant to Chapter 373, Florida Statutes, and Chapter 40E, Florida Administrative Code, is responsible for the permitting and regulation of nonexempt water well drilling within the District's geographical jurisdiction. Unless specifically exempted from permitting requirements, each well must be separately permitted prior to construction. Due to the unique characteristics of wells, well construction permits are issued separately for each individual well and are not issued on a site basis. The Respondent, in the summer of 1990, contracted with the City of Fort Myers, Florida, to construct twenty public water supply wells and eight monitoring wells, all located within the existing city well field site. The Respondent was responsible for compliance with all applicable permit requirements. On December 19, 1990, the Respondent obtained the appropriate city permit for the drilling operation, but did not at that time apply for or obtain any permits as required by the Petitioner. The City of Fort Myers permits wells in compliance with the Standard Plumbing Code, but does not have a well construction ordinance. The city permit does not substitute for the Petitioner's well construction permits. On April 9, 1990, the Petitioner received an inquiry from a representative of the Lee County Health Department as to whether the Respondent had obtained well construction permits from the Petitioner. At that time, there had been no application for the permits submitted to the Petitioner by the Respondent. On April 10, 1990, Don Douglas, Youngquist Brothers manager for the Fort Myers city wells project, contacted the Petitioner and inquired as to the method for obtaining permits for the well construction. Mr. Douglas was advised to immediately cease any well construction operations at the City of Fort Myers well field pending receipt of the appropriate permits. On April 11, 1991, Petitioner's staff inspected the City of Fort Myers well field site, and observed six newly- completed public supply wells on the site. Petitioner's staff again instructed Respondent's representative to cease any further activity. There is no evidence that, subsequent to the Petitioner's directions to cease operations at said site, any additional construction activities occurred. On April 16, 1991, Petitioner's staff again inspected the City of Fort Myers well field site, and observed three additional public supply wells on the site, two of which were surface-cased with the third well appearing to be completed. On May 23, 1991, a Notice of Violation (NOV) was issued to Youngquist citing the failure to obtain well construction permits for the seven completed public water supply wells and the failure to provide notice to the Petitioner 24 hours in advance of the placement of grout in the annular spaces of the seven wells. The Petitioner's staff determined that the extent of the two surface- cased wells construction did not prohibit appropriate inspection even though the wells would also require permitting. As stated in the NOV, the Petitioner sought a fine of $5,000 for the violations. Further, because the Petitioner's staff was first informed by the Respondent's representative that there were six wells completed on site when in fact there were nine, the NOV sought the imposition of a 20% penalty applied to the $5,000, and the suspension of Respondent's well drilling license. Subsequent to the issuance of the NOV, the Petitioner's staff met with Respondent's project manager to discuss the matter. At that time, it was determined that there actually were only six fully completed public water supply wells and three additional surface-cased but incomplete public water supply wells. The Petitioner dropped the proposed 20% penalty and suspension of Youngquist's license. However, subsequent to this discussion, the parties could not resolve the dispute and an Administrative Complaint was filed. 1/ Six individual well construction permits are required for the six completed public water supply wells located at the City of Fort Myers well field. The evidence establishes that the Respondent constructed and completed the six public water supply wells without obtaining the appropriate permits from the Petitioner. The failure to obtain the six permits constitutes six separate violations. The evidence establishes that, in completing the wells, the Respondent failed to notify the Petitioner 24 hours in advance of placement of grout in the annular spaces of the six completed wells. The failure to notify the Petitioner 24 hours in advance of placement of grout in the annular spaces of the six completed wells constitutes six separate violations. There is no evidence that, prior to initiation of the well construction activities and prior to the discovery of the violations by Petitioner's staff, the Respondent made any attempt to comply with the permitting requirements of the Petitioner.
Recommendation Based on the foregoing, it is hereby RECOMMENDED that the South Florida Water Management District enter a Final Order imposing an administrative fine of $4,500.00 against Tim Youngquist. DONE and RECOMMENDED this 14th day of January, 1992, in Tallahassee, Florida. WILLIAM F. QUATTLEBAUM Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 14th day of January, 1992.
Findings Of Fact The Petitioner, Bocilla Waterways, Inc., is a corporate entity formed for the purpose of pursuing the subject project and installing the proposed channel. Randall Craig Noden, secretary- treasurer of that corporation, and a director of it, is a realtor who sells and develops property on Don Pedro Island, in the vicinity of the proposed project. He and other officers and directors of the Petitioner corporation have an interest in property on some, but not all, upland areas adjacent to Bocilla Lagoon, Old Bocilla Pass and Kettle Harbor, the water bodies germane to this proceeding. The Respondent, State of Florida, Department of Environmental Regulation, is a state agency charged with regulating dredge and fill projects in state waters and navigable waters pursuant to Chapters 253 and 403, Florida Statutes, and Rule Chapters 17-3 and 17-4, Florida Administrative Code. The Intervenor, Environmental Confederation of Southwest Florida (ECOSWF), is an incorporated, not-for-profit organization whose membership includes numerous environmentally concerned public interest organizations or associations located throughout southwest Florida. Members of the Intervenor use Old Bocilla Pass, Kettle Harbor, Bocilla Lagoon and Lemon Bay, an adjacent contiguous water body, for boating, swimming, fishing (both recreational and commercial), and collecting shellfish. Some of the membership of the Intervenor live in the immediate area of the proposed project. Project Description The Petitioner submitted a dredge and fill permit application to the Respondent, DER, proposing excavation of an access channel through the uplands of Don Pedro Island and adjacent transitional and submerged lands. The channel would be 100 feet wide, 450 feet long and dredged to a depth of -5.0 feet mean low water, with 2:1 side slopes grading to 3:1 at approximately +0.5 feet NGVD. The channel below mean high water would be 70 feet wide' and 670 feet long to a depth of -5.0 feet mean low water, with 2:1 side slopes. A rip-rap strip five feet wide would be placed in the littoral zone on either side of the channel. As originally proposed, the channel excavation would be performed by dragline and clamshell with spoil placed upon uplands for disposal. The excavation would progress from the west side of the project to the east, with plugs remaining at the eastern terminus of the channel until it stabilizes and the rip- rap is placed along the excavated channel. A turbidity curtain is proposed to be used to maintain water quality above state standards regarding turbidity. The applicant originally proposed to transplant seagrasses, displaced in the excavation process, back into the bottom of the excavated channel. Earthen slopes above mean high water would be vegetated in order to achieve stabilization. Some of these proposals were modified after negotiations with DER staff, such that the seagrass transplanting portion of the project would be accomplished in surrounding areas of the water bottom of Bocilla Lagoon and Kettle Harbor, specifically, bare areas and otherwise degrassed, vegetated flats. The applicant also proposes to install navigation aides in Bocilla Lagoon and Kettle Harbor in order to help maintain boat traffic in the channel, and to facilitate ingress and egress through the proposed channel. Don Pedro Island is a barrier island lying off the coast of Charlotte County, Florida. The only access to the island is by boat or helicopter. Bocilla proposes to excavate the proposed channel in order to, in part, provide better navigational access to Bocilla Lagoon which lies within Don Pedro Island. There is presently a navigational channel in the Bocilla Lagoon through what is called "Old Bocilla Pass," located at the north end of Bocilla Lagoon and communicating with Lemon Bay. Bocilla contends that the channel is somewhat tortuous and subject to shoaling, with concomitant grassbed damage by boat propellers, and that thus, a better navigational access in the form of a shorter, deeper, more direct channel from the southern end of Bocilla Lagoon to Kettle Harbor is required. The project would involve the removal of approximately .18 acres of mangroves (red and black mangroves) and .187 acres of seagrasses. Bocilla has proposed to mitigate the damage involved in the mangrove and seagrass removal by replanting mangroves, on three foot centers, along both sides of the proposed channel, and replanting or transplanting seagrasses in bare areas of Kettle Harbor, near the proposed project. Description of Pertinent State Waters Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass are designated as Class II, navigable waters of the state and are designated for shellfish propagation or harvesting. Shellfish, including clams and oysters, occur in Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass. As demonstrated by Intervenor's witnesses Wade, Cole and Wysocki, shellfish are harvestable and harvested in Bocilla Lagoon and Kettle Harbor at the present time. Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass have also been conditionally approved by DNR for shellfish harvesting. DNR approves or prohibits waters for shellfish harvesting, and as a matter of policy generally prohibits shellfish harvesting in manmade "dead-end" canals. A "conditionally approved" water body, such as those involved herein, is an area approved for shellfish harvesting, but one which is more likely to be affected by pollution events. Thus, they are monitored more closely by DNR. Such events as additional residential development in an area, resulting in more septic tank sewage discharge, on-board toilet discharges from boats or the installation of a water and sewer treatment plant, can result in DNR temporarily or permanently closing a conditionally approved area to shellfish harvesting. Natural phenomenon such as the influx of red tide is also a factor which is considered by DNR in electing to classify a shellfish harvesting area as conditionally approved, and in electing to prohibit shellfish harvesting in an area. It was established through testimony of witnesses Feinstein and Setchfield of DER that long-standing DER policy provides that when DNR conditionally approves waters as being shellfish harvestable, that means they are "approved" for all shellfish harvesting purposes, but simply subjected to closer monitoring and with an increased likelihood of closure due to immediate pollution events. Therefore, the prohibition in Rule 17- 4.28(8)(a), Florida Administrative Code, prohibits issuance of dredge and fill permits in areas approved for shellfish harvesting or "conditionally" approved, since there is no difference in the "shellfish harvestable" nature of the waters until a closure occurs, which may simply occur sooner in conditionally approved waters. Bocilla Lagoon and Kettle Harbor are both naturally- formed water bodies, although some dredging has been allowed to occur in them in the past. They are not manmade, "dead-end" canals. Neither water body has the physical or biological characteristics of a "typical dead-end canal". Both are quite high quality habitats for the natural flora and fauna occurring in the marine environment in that area, and thus the general policy of DNR established by witnesses Cantrell, Fry, Feinstein and Sperling which prohibits shellfish harvesting in manmade, dead-end canals, does not apply to Bocilla Lagoon and Kettle Harbor. The water quality in both bodies of water is good and within DER standards generally. At times however, the water quality in Kettle Harbor suffers from a failure to meet DER dissolved oxygen standards contained in Chapter 17-3, Florida Administrative Code. Indeed, the water quality in Bocilla Lagoon is generally somewhat better than the water quality in Kettle Harbor. Environmental Impacts The project as currently proposed would result in the removal of approximately .18 acres of mangroves and .18 acres of seagrasses. Seagrasses and mangroves are important in providing areas of cover, food, and habitat for various estuarine species. Seagrasses serve to stabilize marine soils resulting in a decrease of suspended solids in contiguous waters with resulting decrease in turbidity in those waters. The loss of seagrasses can result in de- stabilization of the bottom sediment, such that suspended solids or turbidity increases in involved waters, which can result in decreased light penetration to the vegetated bottoms. Decreased light penetration, if of a sufficient degree, can result in the further loss of seagrasses and other bottom flora, causing in turn, increased turbidity and further decreased light penetration, with progressively destructive results to seagrass beds and other marine flora and fauna, with a substantial detrimental effect on the marine biological community in general. Mangroves serve as biological filters, trapping sediments, heavy metals, nutrients and other pollutants, uptaking them through their roots and converting them to usable plant food and thus filtering such harmful elements from state waters and rendering them into environmentally harmless substances. The removal of the mangroves at the proposed channel site will result in a loss of their beneficial effects. These beneficial effects will be absent for a greater period of time than it takes to merely plant replacement mangrove plants, since mature trees will be removed and mangrove seedlings will be replanted in their stead. Maturation of mangroves at this location would take in excess of three years, thus replacement of the beneficial filtering effects of the removed mangroves will take in excess of three years, to which time must be added the time which lapses between the original mangrove removal and the replanting of the seedlings, which would start the maturation period. Bocilla proposes to mitigate the removal of the mangroves by that replanting, as well as to transplant seagrasses removed from the channel site to other nearby areas currently bare of seagrass. Seagrass replanting is not a well-established practice. Compared to mangrove replanting, there is less experience, less information and a lower success ratio historically. Of the hundreds of dredge and fill projects occurring and approved throughout Florida, only three have involved replanting of removed seagrasses. Two of the projects involved the Port of Miami in Dade County and the "New Pass site" in Sarasota County. In both of these cases, seagrass replanting cannot be termed successful. The Port of Miami project resulted in a final survival rate of only twelve per cent of ,the grasses replanted. The New Pass project thus far has resulted in a survival rate of only 39 per cent of the seagrasses replanted, after only nine months. The Petitioner proposes that the replanting be accomplished by Mangrove Systems, Inc. That firm is headed by Robin Lewis, who oversaw the seagrass replanting project at the New Pass area in Sarasota. The location and method of replanting seagrasses at New Pass, as to water depth, type of bottom, type of grass and planting method, was generally similar to that proposed for the Bocilla project. That is, it would be accomplished by "plug planting," of "bald" spots at generally the same latitude and similar water depth. The survival rate at the end of six months at the New Pass project was 73 per cent. The survival rate at the end of nine months was 39 per cent. Mangrove Systems, Inc. and Mr. Lewis acknowledges that it is difficult to attribute the decrease in survival rates and grass shoot densities to any one cause, but that predation and a shift in sediments due to the vagaries of water currents, were probably the chief causes for the decrease in seagrass survival. Mangrove Systems, Inc. and the Petitioner propose a guarantee whereby Mangrove Systems, Inc. would replant more seagrasses, if needed, if a low survival rate occurs, which it defines to mean less than a 70 to 80 per cent survival rate after one or two years. There is no guarantee concerning the survival rate after a second planting, however. It was not established when the survival rate will be measured, in determining whether a 70 to 80 per cent survival is being achieved. In this connection, the central Florida coast where the Bocilla project is proposed, is not as conducive to seagrass growth as other more tropical marine areas, such as in the Florida Keys. In the area of the proposed project, seagrasses do not generally produce a great deal of seed and tend not to grow back very readily, once they are destroyed. Seagrasses in the Florida Keys tend to have, in comparison, much greater seed production and for this and other reasons, tend to reproduce themselves more readily once destroyed. They tend to be more amenable to transplanting in the Florida Keys marine environment. Mangrove Systems, Inc. has conducted a seagrass replanting project in the Florida Keys, however. One-third of the seagrasses planted in that project have not survived after two years. In short, the likelihood of seagrass survival has been insufficiently tested in the geographical area and latitude and in similar soils, water depths and temperatures as those involved in the instant case, such that reasonable assurance of adequate seagrass survival with the replanting project proposed will occur. Hydrographics and Maintenance Dredging The evidence is uncontradicted that the opening of the proposed channel would increase circulation in the southern end of Bocilla Lagoon. Increased circulation tends to have good effects in that it reduces stratification in water bodies. Stratification is a condition which occurs when the deeper waters of a given water body do not interchange with surface waters, but rather stratify or become characterized by layers of differing levels of dissolved oxygen, temperature, pH, etc. Typically, lower levels of a stratified body of water are characterized by low levels of dissolved oxygen. The present water quality of Bocilla Lagoon however, is not characterized by statification in any significant degree. It is very similar in water quality, in terms of dissolved oxygen, temperature, pH and other Chapter 17-3 water criteria, to that water quality of the nearby intra-coastal waterway into which the channel into and through Kettle Harbor would open. The intra-coastal waterway is agreed to be a well- circulated body of water, meeting all current State water quality standards. Accordingly, the opening of the channel and the increased circulation it may cause in the southern end of Bocilla Lagoon would have minimal, positive benefits. The change in circulation and in water current patterns and velocities caused by the opening of the direct, shorter channel from lower Bocilla Lagoon and Kettle Harbor may, negatively affect the present seagrass growth in seagrass beds in Kettle Harbor and Bocilla Lagoon in the vicinity of each end of the proposed channel, due in part to increased current velocities that would result from tidal exchange through the shorter, straight channel which would be opened. The expert witnesses in the area of hydrographics disagreed on the effect of the proposed channel on water circulation in the northern end of Bocilla Lagoon and Old Bocilla Pass, which is the north channel opening into northern Bocilla Lagoon. Witness Sperling for the Department opined that a major reduction in flows through Old Bocilla Pass channel would occur. Witness Tackney for the Petitioner acknowledged there would be some reduction in flow, and witness Olsen opined that a reduction in flow would occur, but there could also be an increase in circulation. Both witnesses Tackney and Olsen, in opining that a flow-through, enhanced circulation and flushing system may result from installing the channel, based that opinion to a significant degree, on their belief on the effects of wind on forcing water through the Pass and Bocilla Lagoon. No wind data or records were adduced however, to show the likely effects of wind on creating the Petitioner's desired "flow-through" system. Witness Sperling disagreed as to the significance of this flow-through effect, but there was no disagreement among the hydrographic experts that reduced flows through Old Bocilla Pass, which all acknowledged can occur to one degree or another, can result in increased sedimentation in Old Bocilla Pass, which can result in turn, in the need for increased maintenance dredging in Bocilla Lagoon and Old Bocilla Pass in the future. Maintenance dredging in Old Bocilla Pass may have to be increased if the proposed channel is constructed. The proposed channel itself will likely have to be periodically maintenance dredged as well. Maintenance dredging can cause environmental problems. Dredging activities result in the loss of marine habitat and the destabilization of marine sediments, with resulting increased turbidity and reduced photic effects, with concomitant detrimental effects on seagrasses and other bottom flora and fauna. Increased turbidity resulting from dredging and destabilization of sediments can directly adversely affect shellfish, including clams and oysters. Dredging impacts and siltation can negatively affect seagrass growth and water quality by increasing turbidity resulting in reduced photosynthesis in seagrass, by smothering the seagrass directly and by silting fauna and vegetation in adjacent productive grassbeds. Persons other than the officers and directors of Bocilla Waterways, Inc. own property and have riparian rights on the Old Bocilla Pass channel. These persons have in the past, and have the right in the future, to use Old Bocilla Pass for navigational purposes and could elect to maintenance dredge Old Bocilla Pass as they have in the past. If the proposed channel is constructed, there is obviously a more direct access and shorter water route between the waters of Bocilla Lagoon and Kettle Harbor. Water quality at times in Kettle Harbor has been worse than that in Bocilla Lagoon, especially in terms of low dissolved oxygen. If poorer water quality exists in Kettle Harbor due to low dissolved oxygen, an influx of red tide or some other cause, the construction of the proposed channel would increase the chance, by the more direct connection and increased flow in the southern end of Bocilla Lagoon, to contaminate the water of Bocilla Lagoon. The Public Interest Public opposition was expressed at the hearing, including that of ECOSWF, the Intervenor, some of whose members include people who live in the area of the proposed channel and use the involved waters. Local fishermen who harvest shellfish and finfish in Bocilla-Lagoon and Kettle Harbor, and use Old Bocilla Pass for navigation between Lemon Bay and Bocilla Lagoon, oppose the project, some of whom are members of the organized Fishermen of Florida, an association of approximately 25,000 members. Residents of Bocilla Lagoon and the immediate area, who habitually navigate Old Bocilla Pass, including local fishermen, have had little trouble navigating Old Bocilla Pass because they are familiar with the channel. Although the Petitioner alleges that the new channel is needed in part for the safety of people living on Bocilla Lagoon to assure quick access to the mainland in case of medical emergencies, the members of the public living on Bocilla Lagoon, (with one exception) and on surrounding areas of the island, do not wish such increased access for medical purposes. The island is presently reached from the mainland by either watercraft or helicopter. Formerly, there was a bridge connecting the island with the mainland which has since been destroyed, and not rebuilt. The residents living on Bocilla Lagoon, either full- time or part-time, buy their homes and choose to live there with knowledge of the present mode of access through Old Bocilla Pass, which is also the means they would achieve access to the mainland in case of medical emergencies or, alternatively, by helicopter transport or by transport over island roads to the ferry landing, with access to the mainland by ferry. The residents, in general, desire to maintain the isolation of life on the island as it presently exists and do not desire enhanced access between the island and the mainland, since part of the charm of having homes and living on the island is its isolation from the more populous mainland. Other than the testimony of Petitioner's witnesses, there was no testimony presented expressing any public need for the proposed channel, as for instance from public officials having knowledge of any medical or public health need for enhanced access to Bocilla Lagoon and the island. The proposed project is contrary to the public interest due to its adverse effects on seagrasses, shellfish, and water quality as delineated above. The adverse effects on seagrasses would result from the dredging itself and the destruction of a portion of the extant seagrass beds, and the resultant likelihood of poor survival rates in the attempted transplanting of seagrass as a replacement for that destroyed by the channel dredging. The proposed project is not in the public interest of those people with riparian rights on Old Bocilla Lagoon and northern Bocilla Lagoon, as there is substantial likelihood the proposed project will reduce flows through Old Bocilla Pass' channel with the resultant increased settling out of sediment and thus increased shoaling of that channel, which would concomitantly increase the need for maintenance dredging in Old Bocilla Lagoon and channel. Additional maintenance dredging and the possible negative effects of such additional dredging on marine, flora and fauna in Bocilla Lagoon and Old Bocilla Pass constitute an additional burden on these riparian owners, the bearing of which is not in their interest. The proposed project is also contrary to the public interest in that the proposed channel is deeper, wider and more direct as an entry into Bocilla Lagoon from Kettle Harbor and Lemon Bay, and would thus allow larger, deeper draft boats to enter Bocilla Lagoon with concomitant increased pollution from oils, greases and possible discharge of onboard sewage, which could have adverse environmental impacts on water quality in Bocilla Lagoon, as well as Kettle Harbor. The use of deeper draft, larger boats with larger propellers and more powerful engines could also result in damage to adjacent grassbeds in the vicinity of either ends of the proposed channel, either through direct propeller contact or through prop wash, when such boats are navigated in areas minimally deep enough to accommodate their draft. Since the installation of the proposed channel would result in a deeper, more readily used access to Bocilla Lagoon by larger boats with the remaining original channel usable also, at least for a time, there is a-substantial likelihood of increased residential development on riparian property around Bocilla Lagoon. This could have the result of reducing water quality in the lagoon, or potentially so, through septic tank leachate, stormwater runoff and other adverse environmental effects, such that the water in the lagoon traditionally approved for shellfish harvesting may be prohibited in the future.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That a Final Order be entered by the Department of Environmental Regulation denying both the variance application and the permit application sought by Bocilla Waterways, Inc.

Findings Of Fact Background On January 29, 1981 respondent/applicant, George H. Hodges, Jr. (applicant or Hodges), filed application number 16 39644 with respondent, Department of Environmenta1 Regulation_ (DER), seeking a dredge and fill permit to generally authorize the excavation of 26,000 cubic yards of material from a 3,700 foot portion of an existing channel (Old Pablo Creek) just west of the Intracoastal Waterway (ICW) in Jacksonville, Florida. The channel then proposed was a straight channel along the northern boundary of his property. Hodges also sought to construct two boat slips, three floating docks, an 850 foot vertical bulkhead adjacent to the docks, and to dispose of all dredged material in a diked upland site. Thereafter, DER informally advised applicant that it intended to deny the application for various reasons, including the fact that the dredging would eliminate .75 acres of marsh and wetlands. After receiving this advice, Hodges proposed a series of amendments to his application in 1984 and 1985 in an effort to counter and satisfy DER's objections. The final amendment was made on September 10, 1985. As finally amended, Hodges proposed to confine all dredging to existing salt channels, thereby eliminating the objection that adjacent marshes would be destroyed. Applicant also proposed to restrict his dredging to only 2,250 feet along the northern portion of Old Pablo Creek and to remove 29,250 cubic yards of fill (silt) and sand and place the same in a 12.5 acre upland spoil site. By proposed agency action issued on February 28, 1985, DER announced it intended to issue the requested permit. This prompted a protest and request for hearing from petitioner, Jacksonville Shipyards, Inc. (JSI), which owns and operates a ship repair facility on the ICW just south of the proposed project. In its petition, JSI generally alleged that (a) Hodges had failed to give reasonable assurances that water quality standards would not be violated, (b) the project would adversely affect its property, (c) the project would have an adverse effect on the conservation of fish and wildlife, (d) the project would cause harmful erosion or shoaling, (e) DER failed to consider the long-term effect of the project on marine productivity and the cumulative impact of the project, and (f) the proposed vertical bulkhead did not meet statutory requirements. The Project The project site is a shallow horseshoe shaped creek approximately 3,700 feet in length which meanders through a vegetated salt marsh just west of the ICW in Duval County, Florida. Both ends of the creek connect into the ICW. The site is approximately one-half mile north of the bridge on Atlantic Boulevard which crosses the ICW. The ICW is a man-made channel constructed by the U. S. Corps of Engineers which runs in a north-south direction just east of the project site. It is commonly referred to as Pablo Creek. The channel or creek in which the dredging will occur is known as Old Pablo Creek (creek). An excellent aerial view of the entire area is shown in petitioner's exhibit 4 received in evidence. The creek is a predominately marine water classified as a Class III water of the State. Accordingly, it is subject to DER's regulatory jurisdiction. For purposes of this hearing, the parties have referred to the upper and lower portions of the creek as the northern and southern portions, respectively. Hodges intends to dredge the northern portion of the creek, which measures approximately 2250 feet in length from the ICW to a bend at its western end which crosses Hodges' property and where a residential site is located. According to Hodge's affidavit of ownership, he is the "fee interest owner of adjoining lands except for the dredge channel which is owned by the State of Florida". He acknowledged, however, that the residential site is owned by his superintendent, and that the marshes adjoining the most southern bend in the northern portion of the creek, and the southern portion of the creek, are owned by JSI. Except for the cleared residential site at its western end, the creek is surrounded by vegetation and salt marshes. The vegetated portion of the marsh is marked by a clearly delineated edge which separates it from the creek bottom. The dominant species of vegetation in the marsh are Juncus and Spartina. The marsh serves as a habitat and breeding ground for numerous species, including fiddler crabs, mussels, barnacles, mollusks, faunal communities and gastropods. In addition, the marsh is beneficial because of its biotic productivity and entrapment of nutrients and sediments. For this reason, the habitat should be maintained. Some forty years ago, the portion of the creek that Hodges intends to dredge was eight to twelve feet deep. However, dredging of the ICW by the Corps of Engineers and the placement of fill at the site of the Atlantic Boulevard Bridge have contributed to the shallowing of the creek over time. Today, portions of the creek are exposed and impassable under low tide conditions. Indeed, many parts of the creek are dry during the low tide phase of the ICW. At high tide, the creek is flooded to an approximate depth of four feet. Hodges proposes to dredge the creek channel to a uniform depth of five feet below mean low water (MLW) with side slopes at a 3:1 ratio to restore navigational access from his upland property to the ICW. He has represented that his use of the channel will be restricted to one, or possibly two, small boats for personal use and enjoyment. When completed, the creek channel will have a depth of nine feet at high tide, or an average depth of seven feet over a diurnal cycle. In his amended application, Hodges proposed to confine his dredging to existing creek channels, and to not disturb the actual body of the salt marsh or the vegetation bordering the creek. It is noted that there is no vegetation growing in the existing creek bottom. However, at hearing he conceded that dredging "may include some minor removal of isolated patches of grass growing in the creek channel". One such patch of grass lies in the elbow of the canal which reaches south of Hodges' property, a patch separated from the main body of the marsh by a five foot wide slough deep enough to be navigated at high tide. Hodges estimates this patch of grass to be less than 1/100 of an acre in size (10' x 40') and maintains the effect of its removal would be negligible. The excavation will be effected by means of a Mud Cat hydraulic dredge which operates by suctioning the sediment and water into a pipe. The dredge material (sediment/water mixture) will then be pumped into a series of containment cells on a 12.5 acre upland spoil site that lies approximately one-half mile northeast of the project. Any discharge from the spoil site will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. The natural grade of the existing creek bottom is at or below the mean low water datum. At high tide the existing creek is 4.3 feet deep at its deepest point and gradually slopes upward to a depth of 2.4 feet near the marsh. The elevation of the creek where it meets the marsh is close to mean high water. Even so, the channel width does not always correspond with the mean high water line boundaries of the creek, and creek waters sometimes inundate and extend back into the marsh at high tide. Because Old Pablo Creek is tidally influenced, any water quality violations in the northern portion of the creek can be expected to also have an adverse effect in the southern portion as well. Creek Width Petitioner has raised the issue of whether the creek is as wide as Hodges represents it to be on the drawings attached to the amended application. This is significant since (a) the engineering plans are based upon the assumption that the measurements in the application are correct, (b) the proposed dimensions (depth and side slopes) of the new channel are dependent upon the existing creek having a minimum width of from sixty to eighty feet, as represented by Hodges, and (c) any excavation outside of the existing channel will result in the removal (destruction) of vegetation and marsh. In his application, Hodges reflects the top width of the creek to be sixty to eighty feet, which width will enable him to dredge the channel to an average depth of five feet below MLW, and maintain a side slope ratio of 3:1. This ratio is necessary because of the composition of the sediment in the creek. The minimum top width required to excavate a channel with 3:1 side slopes to a depth of five feet below MLW is fifty- four feet. Petitioner's exhibit 4 identifies five points along the eastern half of the northern portion which have been measured by the parties to determine the actual width of the creek. Although only five points were measured, it may be inferred that these distances are representative of the creek's width throughout its eastern half. At points five through eight, the widths are forty-nine, thirty-five, fifty and fifty feet, respectively, which are less than the measurements contained in the application. If the channel is constructed with the minimum top width (54 feet) required to have 3:1 side slopes, it will result in the elimination of 6 feet of marsh at point 5, 19.5 feet of marsh at point 6, and 4.1 feet of marsh at both points 7 and 8. This equates to the elimination of approximately .33 acres of marsh. Since the above measurements are representative of the eastern half of the northern portion, other areas of vegetation, albeit in unknown proportions, would also have to eliminated. If, for example, applicant attempts to construct a channel within the confines of the portion of the creek that has a top width of only thirty-five feet (point 6), the maximum channel that could be constructed would be V-shaped with a depth of one foot at low tide. Assuming the remaining part of the channel was excavated to -5' MLW, a stagnant area would develop in this portion of the channel and adversely affect water quality. However, to counter the problem at point 6, Hodges intends to remove one patch of grass 10' by 40' in size to achieve the desired width. Any adverse effects on the adjacent marsh at that particular point would be negligible. Because the estimated creek width is not accurate, even the agency now concedes the engineering plans are no longer useful. As a condition to the issuance of a permit, DER has suggested that Hodges be required to submit new certified engineering drawings depicting the proposed cross-section of the channel. It also suggests that the proposed cross-section comply with the top-widths depicted in applicant's exhibit 53, and depict side-slopes of three to one. It further suggests that a condition for the issuance of any permit be a requirement that the 3:1 ratio be maintained, and that other than point 6, no other grass be removed. Finally, the agency proposes that if the new plans and conditions do not permit a -5 MLW depth, the proposed depth be reduced accordingly. However, the evidence supports a finding that either vegetation must be removed at various points along the eastern half of the creek in order to maintain a 3:1 ratio for side slopes, or the depth must be reduced. By reducing the depth at certain points, stagnant areas in the creek will develop, thereby adversely affecting the quality of the water. Further, as noted hereinafter, the validity of the flushing analysis performed by applicant's experts rests upon the assumption that a -5' MLW uniform depth will be used. Finally, the applicant has not given reasonable assurance that the marsh and habitat will not be adversely affected by the elimination of the vegetation which is necessary to achieve the desired depth and concomitant 3:1 ratio. Therefore, the alternative conditions suggested by DER are neither reasonable or appropriate. The Spoil Area The spoil area to be used by applicant is a 12.5 acre upland disposal site approximately one-half mile northeast of Hodges' property. Applicant does not own the upland spoil site but has obtained easements from the owner which expire in March, 1987. In other words, he must complete all work on the project by that date or lose access to the property. The proposed spoil site is completely diked, and is sectioned off into three sections by interior dikes with overflow pipes. Internal baffles and silt fences are also designed into the area. Uncontradicted testimony established that the spoil area is "unusually well designed". Any discharge from the spoil area will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. Discharge, if any, will be outfall from an overflow structure in the third section of the spoil area to a dump area land then by sheet flow to salt marshes adjacent to Greenfield Creek. The vegetation in Greenfield Creek consists of a salt marsh expanse of Spartina alterniTlora and Juncus roemerianus. Both species survive in and are indicative of regular introduction of saline waters, and show high tolerance to varying salinity levels. If saline waters from Old Pablo Creek were introduced into Greenfield Creek, it would have no adverse impact on the Greenfield Creek ecosystem. The size of the site was originally designed for a project of 100,000 cubic yards. The site will retain all |effluent from the dredging. The expected total effluent, both sediment and water, is roughly 5.3 million cubic feet of material, assuming a ratio of 6.7 cubic feet of water for each |cubic foot of sediment dredged. This is slightly lower than the 5.4 million cubic feet total capacity of the site. The supernatant from the discharge being deposited into the first cell of the spoil area will only flow into the next cell when the first cell fills and the level of the supernatant rises above the top of the vertical drain pipe overflow structure. If rainfall events cause the cells to fill with water during dredging and discharge operations, the discharge to the next cell or to Greenfield Creek will be primarily fresh water. This will occur because introduction of fresh rainwater into the brackish water from the dredge area will cause stratification, and the fresh rainwater will form a layer on top that will flow into the overflow structure. Turbidity Effects In removing the mud bottom from the creek to a depth of -5' MLW, some turbidity will occur. This is a natural by- product of using the hydraulic dredge. However, the amount of turbidity, and its effect on the waters at the dredge site and discharge point, are in issue. State water quality standards prohibit the discharge of water with a turbidity level greater than twenty-nine nephelometric units (NTU's) above the background levels of the receiving waters. The evidence indicates that the background turbidity levels at the creek are now in the range of ten to twenty NTV's. Excessive levels can result in adverse effects on local biota such as decreasing productivity by reducing light penetration. Excessive turbidity can also be expected to suffocate organisms. The area to be dredged contains sediment deposited from the surrounding salt marsh and carried in from the ICW. The sediment is composed of 14% clay, with the remainder being sand and silt. This was confirmed by a laboratory analysis conducted by JSI. As a general rule, the coarser the material, the faster it tends to settle out thereby creating less turbidity problems. Therefore, sand, which is of a grain size, can be expected to settle out quickly while silt takes somewhat longer. However, clay size particles are much smaller than silt and do not settle out as easily. Applicant made no laboratory analysis of sediment and consequently he erroneously assumed the mud to be sand and silt, and did not take the clay particles into account. The dredging in the creek will cause the turbidity levels to rise to 150 NTU's. However, the placement of a turbidity screen at the entrance to the ICW will prevent the release of this turbidity into that water body. Therefore, if a permit is issued, such screens should be used by Hodges at the dredge site. At the spoil site, clay size particles will also be included in the matter pumped for discharge. If these particles do not settle out, or are not treated, their discharge into Greenfield Creek (a jurisdictional water) will cause violations of the turbidity standards. To counter their effects, flocculants (chemicals) should be added when necessary to the confined material to aid the particles in settling. If a permit is issued, this should be made a condition in the permit. Dissolved Oxygen Impacts The dissolved oxygen (DO) levels in the creek fluctuate on a daily and seasonal basis. As a general rule, DO levels tend to be lower in warmer weather and during the early morning hours. Therefore, a "worst case" situation will generally occur in the summer months in the early part of the day. State water quality standards contained in Rule 17- 3.121(13), F.A.C., provide that in predominately marine waters, the concentrations of DO "shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter." Sampling conducted by petitioner at 5:00 a.m. in early July, 1986 during high tide revealed readings ranging from 3.06 mg/1 in the western portion of the creek to 4.59 mg/1 at the mouth of the creek. Dissolved oxygen levels in the ICW ranged from 3.94 to 4.68 mg/1. Hodges also sampled the creek and ICW in the late morning or early afternoon on August 6,1986 and determined DO levels to be 4.8 mg/1 in the creek and 5.8 mg/1 in the ICW. Testing at that hour of the day produced higher values than those found by JSI. The readings collectively confirm that DO levels in the creek are approximately 1.0 mg/1 less than the DO levels in the ICW. This deficit is primarily caused by the high oxygen demand exerted by the adjacent marsh and muds in the creek. This situation will not be changed by the dredging. The flushing time of the creek channel is an important factor in predicting post-dredging impacts on water quality. Flushing time determines how rapidly waters of the ICW will exchange and mix with the water in the creek channel. Both Hodges and JSI conducted tidal prism studies to determine how many tidal cycles would be required to flush a hypothetical pollutant to 10% of its initial concentration. Under worst case conditions, the channel is expected after dredging to flush every 3 to 4 tidal cycles or 1.6 days. Under more favorable conditions, the creek is expected to flush every 2 to 3 tidal cycles. This compares with the current system which flushes almost 100% every tidal cycle or once every twelve hours. The increased flushing time is due to the significantly greater volume of water that will enter the creek channel after dredging. Because of increased channel depths, the water will move at a slower velocity. Therefore, the oxygen consuming components have a longer period of time to react in the water column. This in turn will cause reductions in DO levels of between .7 mg/l and 1.5 mg/l in the creek. This was confirmed through tidal prism modeling performed by JSI. In this regard, it is noted that JSI's modeling was more sophisticated, better calibrated, and its assumptions were more accurate and reasonable. Consequently, its testing results are considered to be more reliable and persuasive than that of applicant. It must also be recognized that the deepening of those areas that are currently exposed at low tide will allow water to move more easily through the channel and remove some oxygen demanding sediments that now draw from a shallow water column. This will tend to have a beneficial effect on water quality. However, the overall impact of these beneficial effects is unknown, and it was not demonstrated that the otherwise adverse effect on DO will be offset or minimized by the unmeasured impact of deepening the shallow areas. Therefore, applicant has not given reasonable assurance that water quality standards will not be violated by the project. At the same time, it must be further noted that a reduction in the channel depth due to the smaller width of the creek will alter the results of the tidal prism studies, as well as negate some of the beneficial effects caused by deepening the shallow portions of the channel. To what extent the studies are changed, or benefits will be reduced, is not of record. Other Effects of Project As noted earlier, Hodges intends to use one or two boats on the deepened channel. The use of the boats will not introduce pollutants in any significant quantity. Hodges proposes to construct his docks and place rip- rap on the northern side of the widest portion of the creek channel. Little, if any, vegetation will be eliminated by these activities. The use of rip-rap for the construction of the bulkhead is the most environmentally sound means of bulkheading, and will stabilize the shoreline as well as provide habitat for aquatic organisms. The dredging of the creek channel will improve the navigability of the creek, and permit the use of boats in areas where access is now impossible under low-tide conditions. In addition, the sharp bends in the creek will prevent the operation of boats at high speeds. JSI's concern that boats may run aground once they leave the northern portion and enter the southern portion is not meritorious since few, if any, are expected to use the latter part of the creek, and the sharp bends will force boaters to operate at low speeds. Shoaling or erosion of the southern portion will not result from the proposed activities. Indeed, an increased flushing and introduction of new flow into the system may benefit the northern portion. Any situation occurring in that part of the creek should not exceed the rate of siltation occurring under current conditions. The benthic organisms which populate the bottom of Old Pablo Creek include crabs, mussels, barnacles and other species normally associated with estuarine systems. The removal of the mud bottom in the dredging operation may remove some of these organisms. However, this should not significantly change the habitat of these benthic organisms. Rapid recolonization by these species would be expected with recolonization substantially underway within forty-eight hours
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that application number 16-39644 of George H. Hodges, Jr. for a dredge and fill permit be DENIED.
