The Issue The issue in this case is whether the Southwest Florida Water Management District (SWFWMD) should grant Individual Environmental Resource Permit (ERP) Application No. 4316067.00 for approval of a proposed surface water management system (SWMS) for a planned road improvement project.
Findings Of Fact County Line Road extends a short distance east from its intersection with U.S. 41, approximately along the boundary between Pasco County and Hillsborough County. It currently serves as access to residential and rural areas in its vicinity but does not connect with any major road east-west roadway at its eastern end. Since at least 1995, Pasco County's Metropolitan Planning Organization (MPO) has considered it necessary by 2020 to connect County Line Road to Collier Parkway (which runs north and south to the east and north of County Line Road but connects at its southern end to Hillsborough County Road, which extends from there to the east) to create and serve as another major east-west roadway to alleviate traffic congestion on State Road 54 to the north. The MPO's plans are updated continually, most recently in 1998. The MPO's current plans call for building a half-mile segment of two-lane roadway by 2000 to connect County Line Road to Collier Parkway and widening it to a four-lane road by 2010. Once these plans were made, and the general corridor for the new roadway chosen by the MPO, Pasco County conducted a route study and decided to utilize and improve the existing County Line Road to the extent possible consistent with traffic safety considerations before routing the new roadway to the northeast towards a connection with existing roadway (known as Willow Bend Road), which in turn connects with Collier Parkway. In so doing, Pasco County would improve County Line Road where it now crosses 13-Mile Run Creek. 13-Mile Run Creek is the name for the water body and wetland area crossed by County Line Road. It is part of a system of connected lakes, wetland areas, and various natural and man- made water conveyances known as the 13-Mile Run that begins to the north of County Line Road in Pasco County and flows south into Cypress Creek and the Hillsborough River in Hillsborough County. After completing the route study, Pasco County surveyed the project area and identified wetlands in the project area. Then, the road improvements and new roadway, including the surface water management system, were designed. Pasco County designed its road project to accommodate widening to four lanes in 2010 without further direct impact to wetlands. This will allow traffic to flow much more safely on the two lanes built in 2000 while the additional two lanes are built in 2010. As part of this design, the culverts that will provide for north-to-south flow of 13-Mile Run under the roadway, as well as the animal-crossing tunnels under the roadway, will be oversized to accommodate the four-lane roadway in 2010. As a result, all direct impacts to wetlands from the ultimate four- lane road construction (approximately 1.5 acres of direct impact) will occur during the initial construction of two lanes in 2000; there will not have to be any additional wetland impacts in 2010. The Petitioner and Intervenors contend that Pasco County did not prove a need for the four-lane road Pasco County proposes for 2010. They point to evidence that Florida Department of Transportation (DOT) 1995 maps did not "code" the proposed road segment as a four-lane road in 2010, as well as evidence that in 1995 Hillsborough County objected (based on the DOT coding) to Pasco's plans for a four-lane road in 2010. But Pasco County proved that DOT's failure to code the proposed road segment as a four-lane road in 2010 was a mistake. Since 1995, DOT has corrected the error. When Pasco County's MPO updated its transportation plan in 1998, neither Hillsborough County nor anyone else objected to the plans for a four-lane road in 2010, despite Pasco County's solicitation of comments and advertised public workshops and hearings. The Intervenors in particular also point to evidence that the DOT has published "Standards for Low and High Volume Highways in Annual Average Daily Volumes" in a Manual of Uniform Minimum Standards for Design, Construction and Maintenance for streets and Highways (1994)(also known as the "Green Book"). These standards characterize a two-lane urban collector highway with less than 11,000 AADT and a four-lane urban collector highway with less than 37,000 AADT as low-volume facilities and characterize a two-lane urban collector highway with more than 16,000 AADT and a four-lane urban collector highway with more than 45,000 AADT as high-volume facilities. Meanwhile, there was evidence was that, using a regional traffic demand forecasting model developed by DOT to determine future transportation needs for planning purposes: (1) Pasco County's MPO forecasts approximately 12,500 to 13,000 vehicles per day on the road in 2010 and 16,000 vehicles per day on the road in 2020; and (2) in 1997, the MPO forecasts 12,000 vehicles per day (1078 peak hour) on the road by 2015. But the only explanation of this evidence was the testimony of the MPO's transportation planner that the "Green Book" is not used for purposes of planning to meet future transportation needs. There was no other evidence as to the significance or proper use of the "Green Book." Assuming that AADT means "annual average daily trips" (there was no evidence as to what it stands for), there was no evidence that the Pasco County MPO's plan to four-lane County Line Road in 2010 is inconsistent with the "Green Book." The Intervenors also contend that the planned widening of State Road 54 will eliminate the need to four-lane the proposed road improvements at County Line Road. But the MPO's transportation planner testified that the MPO's forecast of the need to do so took into account the planned State Road 54 improvements. The Intervenors also contend that the proposed road improvements at County Line Road will not serve as an alternative to State Road 54 because Collier Parkway is a north-south highway, not an east-west highway. But, as indicated in Finding 1, supra, utilizing Collier Parkway for a short, north-south jog will connect the east-west roadways on either side of Collier Parkway. The Petitioner and Intervenors contend that Pasco County's design does not minimize direct impacts to wetlands precisely because it is designed to accommodate the four-lane widening project in 2010. Clearly, the direct impact to wetlands in 2000 could be reduced if Pasco County's design only accommodated a two-lane road. But it is not clear that the cumulative impact to the wetlands through the year 2010 will be less if the wetlands have to be impacted twice, once in 2000 for two lanes of roadway and again in 2010 for the other two lanes. A Department of Environmental Protection (DEP) witness for the Intervenors believed that it was preferable not to accommodate two additional lanes during the initial construction. But his familiarity with Pasco County's application was limited (in part because DEP has no regulatory jurisdiction), and several other experts testified persuasively that Pasco County's design would be better in terms of minimizing total, cumulative direct and secondary impacts to the wetlands. It also would cost significantly less to build the four-lane road in two stages if the first stage of construction of two lanes accommodates the subsequent stage of construction of the two additional lanes. In addition, traffic flow would be safer during construction of the two additional lanes if the first stage of construction accommodates the subsequent stage. Given the plan to accommodate a four-lane road in 2010, Pasco County designed its road project to minimize direct impacts on wetlands. First, the design uses the existing road in the wetland area. Second, the design uses concrete retaining walls instead of earthen berms in the wetland areas, which reduces the direct impact to the wetland areas by 30 percent. Third, the design was modified to further reduce the direct impact to wetlands by reducing the width of the median and eliminating one of two sidewalks at the creek crossing. The only way to further reduce the direct impacts to wetlands would have been to design and construct a bridge to cross the wetlands. The Intervenors called their DEP witness to testify in support of their contention that Pasco County should be required to bridge the wetlands. But again, the DEP witness's knowledge of Pasco County's application was limited, and several other witnesses testified persuasively that such a requirement for this road improvement project would be unreasonable in light of the existing County Line Road (which is a fill road.) In addition, bridging 13-Mile Run would create water flow and quantity problems that would have to be addressed, since it would remove the existing roadbed that serves to stop flow in times of high water. See Finding 19, infra. Pasco County's design provides for two wet detention ponds, one at either end of the project area, that will treat one-inch of runoff from the project area and will retain all of the runoff from a 25-year, 24-hour storm (nine inches of runoff.) As a result, there are reasonable assurances that there will be no adverse impact on water quality from the project; to the contrary, water quality probably will improve since the existing County Line Road does not provide any water treatment. Likewise, Pasco County has provided reasonable assurances that water discharges from the project area will not increase. As a result of the project, approximately 3.5 acre-feet of flood plain storage will be eliminated. To more-than- compensate for this loss of flood plain water storage area, Pasco County's design includes a flood plain mitigation area of approximately 4.5 acre-feet with a connection to 13-Mile Run Creek. The flood plain mitigation area also will serve as the project's wetland mitigation area at a ratio of approximately 4- to-1, i.e., four acres of created wetland for each acre of direct wetland impact. (Wetlands disturbed by the illegal installation of a Florida Gas Transmission pipeline just north of County Line Road and now under court-ordered restoration are considered pristine wetlands for purposes of the wetland mitigation ratio.) While wetland restoration has a mixed record of success, and it may be difficult to restore all of the values of the original wetland, the prospects for success of Pasco County's proposed wetland mitigation area are reasonably good. The mitigation plan calls for planting 780 emergent woody species per acre. To the extent that the mitigation plan for this project will replace disturbed wetlands and wetlands not successfully restored by the restoration of the area impacted by the Florida Gas Transmission pipeline (which appears to have been either inadequately planned or poorly implemented), the project may well result in a net improvement of the wetlands in the 13-Mile Run Creek area. Impacts from the roadway immediately to the west of the project area have been addressed in the SWMS permit for construction at the intersection of U.S. 41 and County Line Road. Impacts from Hillsborough County's planned widening of the roadway immediately to the west of the project area will be addressed in the SWMS for that widening project. The Petitioner in particular raised the question of flooding in the vicinity--at the U.S. 41/County Line Road intersection and along the shores of Hog Island Lake to the southeast of the creek crossing. The Intervenors initially also raised those questions but have been satisfied by the assurances given by Pasco County that the proposed project will not increase flooding in those areas. The SWMS associated with construction of the U.S. 41/County Line Road intersection appears to have been successful in alleviating flooding there, and Pasco County has given reasonable assurances that the proposed road project in this case will not increase flooding in the Hog Island Lake area. The generous flood retention compensation proposed by Pasco County may alleviate flooding in the Hog Island Lake area to some extent. It also is noted that, if the project were modified to bridge the creek crossing (without any other modifications), flooding in the Hog Island Lake area could increase. See Finding 13, supra. The Petitioner also opposed Pasco County's SWMS application on the ground that no minimum surface or ground water levels or minimum surface water flows have been established in the area under Section 373.042, Florida Statutes (1997). But Pasco County provided reasonable assurances that, regardless where the minimum levels ultimately are set, the proposed project will have no appreciable effect. Pasco County has designed the project to maintain water current flows and quantities. It is found that Pasco County has implemented practicable design modifications to reduce or eliminate adverse impacts of the proposed project. (As used here, the term "modification" does not include the alternative of not implementing the SWMS in some form, nor the alternative of a project that is significantly different in type or function from that proposed.) As used in the preceding finding, the term "practicable" would eliminate modifications which would adversely affect public safety through the endangerment of lives or property. For example, one modification suggested by the Petitioner and Intervenors would have been to have the new road follow existing County Line Road further to the east. However, that would have made the connection between the new road and what would remain of County Line Road hazardous at the design speed of the new road and, depending on how much further east the new road follow existing County Line Road, there would be the hazard of residential driveways connecting to the new road. As used in Finding 21, the term "practicable" also would eliminate modifications which are not technically capable of being done or not economically viable. While there was no evidence that alternatives considered in this case were either not technically capable of being done or not economically viable, general consideration was given to the higher total project costs of not accommodating the planned addition of two lanes in 2010 (with no appreciable environmental benefit). Likewise, general consideration was given to the significantly higher cost (approximately two to three times as much, depending on whether the construction of the first two lanes accommodates the subsequent construction of the two additional lanes) to bridge the wetlands in an attempt to reverse direct wetland impacts from the existing fill road and somewhat decrease additional direct wetland impacts, as well as the dubious benefits of increasing the flow of 13-Mile Run, which certainly would not reduce (and might well increase) flooding in the Hog Island Lake area. In addition, bridging the creek crossing would create traffic engineering problems in providing access to residential areas in the vicinity, especially the Foxwood subdivision. Pasco County provided reasonable assurances that its proposed SWMS, with SWFWMD's general and specific conditions, will not violate state water quality standards applicable to waters as defined in Section 403.031(13), Florida Statutes (1997). Pasco County provided reasonable assurances that its proposed SWMS, with SWFWMD's general and specific conditions, will not be contrary to the public interest, considering and balancing the following factors: Whether the proposed project will adversely affect the public health, safety, or welfare or the property of others; Whether the activity will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the activity will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; Whether the activity will be of a temporary or permanent nature; Whether the activity will adversely affect or will enhance significant historical and archaeological resources under the provisions of Section 267.061, Florida Statutes (1997); and The current condition and relative value of functions being performed by areas affected by the proposed activity. To the extent that the proposed project may not meet one or more of the public interest test criteria, Pasco County proposes mitigation measures that will offset any adverse effects. Pasco County provided reasonable assurances that its proposed SWMS, with SWFWMD's general and specific conditions: will not cause adverse water quantity impacts to receiving waters and adjacent lands; will not cause adverse flooding to on- site or off-site property; will not cause adverse impacts to existing surface water storage and conveyance capabilities; will not adversely impact the value of functions provided to fish and wildlife, and listed species including aquatic and wetland dependent species, by wetlands, other surface waters and other water related resources of the District; will not adversely affect the quality of receiving waters such that the water quality standards set forth in chapters 62-3, 62-4, 62-302, 62-520, 62-522 and 62-550, Florida Administrative Code, including any antidegradation provisions of sections 62- 4.242(1)(a) and (b), 62-4.242(2) and (3), and 62-302.300, Florida Administrative Code, will be violated; will not cause adverse secondary impacts to the water resources; will not adversely impact the maintenance of surface or ground water levels or surface water flows established pursuant to Section 373.042, Florida Statutes (1997); will not cause adverse impacts to a work of the District established pursuant to Section 373.086; is capable, based on generally accepted engineering and scientific principles, of being effectively performed and of functioning as proposed; and will be conducted by an entity with financial, legal and administrative capability of ensuring that the activity will be undertaken in accordance with the terms and conditions of the permit, if issued. Pasco County provided reasonable assurances that that its proposed SWMS, with SWFWMD's general and specific conditions, will not cause unacceptable cumulative impacts upon wetlands and other surface waters, as delineated pursuant to the methodology authorized by subsection 373.421(1), Florida Statutes (Supp. 1998).

The Issue The issue is whether the applicant for an Environmental Resource Permit ("ERP"), the City of Deltona ("City" or "Applicant"), has provided reasonable assurance that the system proposed complies with the water quantity, environmental, and water quality criteria of the St. Johns River Water Management District's ("District") ERP regulations set forth in Florida Administrative Code Chapter 40C-4, and the Applicant's Handbook: Management and Storage of Surface Waters (2005).
Findings Of Fact The District is a special taxing district created by Chapter 373, Florida Statutes, charged with the duty to prevent harm to the water resources of the District, and to administer and enforce Chapter 373, Florida Statutes, and the rules promulgated thereunder. The City of Deltona is a municipal government established under the provisions of Chapter 165, Florida Statutes. The Lake Theresa Basin is comprised primarily of a system of interconnected lakes extending from Lake Macy in the City of Lake Helen to the Butler Chain of Lakes (Lake Butler and Lake Doyle). The Lake Theresa Basin is land-locked and does not have a natural outfall to Lake Monroe and the St. Johns River. In 2003, after an extended period of above-normal rainfall in the Deltona area, the lakes within the land-locked Lake Theresa Basin staged to extremely high elevations that resulted in standing water in residential yards, and rendered some septic systems inoperable. Lake levels within the Lake Theresa Basin continued to rise and were in danger of rising above the finished floor elevations of some residences within the basin. On March 25, 2003, the District issued an Emergency Order (F.O.R. No. 2003-38) authorizing the construction and short-term operation of the Lake Doyle and Lake Bethel Emergency Overflow Interconnection. Since wetland and surface water impacts would occur, the Emergency Order required the City of Deltona to obtain an ERP for the system. The project area is 4.1 acres, and the system consists of a variable water structure on the west shore of Lake Doyle connected to a series of pipes, swales, water control structures, and wetland systems which outfall to a finger canal of Lake Bethel, with ultimate discharge to Lake Monroe and the St. Johns River. The first segment of the system extends downstream from the weir structure on the west shore of Lake Doyle via a pipe entrenched in the upland berm of the Sheryl Drive right-of-way. The pipe passes under Doyle Road and through xeric pine-oak uplands to the northeast shore of a large (approximately 15 acres) deepwater marsh. Water flows south through the deepwater marsh where it outfalls through four pipes at Ledford Drive. Two of the four pipes are overflow structures, controlled by canal gates. The pipes at Ledford Drive discharge into a ditch and into a large (greater than 20 acres) shallow bay swamp. The south end of the bay swamp is defined (and somewhat impounded) by a 19th Century railroad grade. Water flows through the bay swamp where it outfalls through five pipes at the railroad grade. Three of the five pipes are overflow structures, controlled by channel boards. The pipes at the railroad grade discharge to a 1500-foot long finger canal that was dug some time during the period 1940-1972 from the north central shore of Lake Bethel. The overflow interconnection system has three locations whereby the system can be shut down: 1) Lake Doyle--a control weir, controlled by three sluice gates; 2) Ledford Drive--two thirty-inch reinforced concrete pipes, controlled by canal gates; and 3) railroad grade--three thirty-inch reinforced concrete pipes, controlled by channel boards (collectively referred to as "Overflow Structures"). The Overflow Structures are designed to carry the discharge of water from Lake Doyle to Lake Bethel. With the Overflow Structures closed the system returns to pre-construction characteristics, meaning there will be no increase or decrease in the quantity or quality of water throughout the path of the system as a result of the project. An unequivocal condition of the permit is that the system would operate with all of the Overflow Structures closed. As an added assurance, the City proposes to place a brick and mortar plug in the Lake Doyle weir structure outfall pipe to prevent any discharge from the weir. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the water level in Lake Doyle rises above an elevation of 24.5 feet. The District shall require a separate permit application to be submitted for such future plans. Petitioner, Barbara Ash, has lived on Lake Theresa for 19 years. Ms. Ash lives upstream from the area of the weir that will be plugged in accordance with the ERP. She does not trust either the City of Deltona to comply with or the District to enforce the conditions of the ERP applied for by the City. Petitioner, Barbara Ash, also served as the qualified representative for Petitioners, Francell Frei, Bernard J. and Virginia Patterson, and Ted and Carol Sullivan. Ms. Ash represented that Ms. Frei has lived on Lake Theresa for 12 years, and both the Pattersons and the Sullivans live on Lake Louise, which is within the area of concern in this proceeding. Petitioner, Diana Bauer, has lived on Lake Theresa since February 2004. She fears that the lake will become too dry if the system is allowed to flow. She also believes the wildlife will be adversely affected if the water levels are too low since many species need a swampy or wet environment to thrive. She fears her property value will decrease as a result of the approval of the ERP. She also does not trust either the City to comply with or the District to enforce the conditions of the ERP. Petitioner, Howard Ehmer, lives two to three hundred yards down Lake Theresa from Ms. Bauer. He is concerned about the lake bed being too dry and attracting people on all terrain vehicles who enjoy driving around the lake bottom. He is concerned about his property value decreasing if the lake bed is dry. Further, when the lake level is too low, people cannot enjoy water skiing, boating, and fishing on Lake Theresa. Petitioner, Phillip Lott, a Florida native, has also owned and lived on property abutting Lake Theresa since 1995. Mr. Lott has a Ph.D. in plant ecology, and M.P.A. in coastal zone studies, an M.B.A. in international business, and a B.S. in environmental resource management and planning. Mr. Lott has been well acquainted with the water levels on Lake Theresa for many years. Based upon his personal observations of the lake systems in the Deltona area over the years, Mr. Lott has seen levels fluctuate greatly based upon periods of heavy and light rainfall. Mr. Lott is concerned that the District will permit the City to open the weir to let water flow through the system and cause flooding in some areas and low water levels in other areas. He fears that the District will allow the water to flow and upset the environmental balance, but he admits that this ERP application is for a closed system that will not allow the water to flow as he fears. Mr. Lott similarly does not trust the City to comply with and the District to enforce the conditions of the ERP. Petitioners, James E. and Alicia M. Peake, who were represented by Steven L. Spratt at hearing as their qualified representative, live on Lake Louise, which is interconnected with the Lake Theresa basin. The Peakes are concerned that if the level of Lake Louise drops below 21 feet, nine inches, they will not be able to use the boat launch ramps on the lake. Petitioner, Steven L. Spratt, also lives on Lake Louise, and is concerned about the water levels becoming so low that he cannot use the boat launch on the lake. He has lived on the lake since 2000, and remembers when the water level was extremely low. He fears that approval of the ERP in this case will result in low levels of water once again. Petitioner, Gloria Benoit, has live on Lake Theresa for two years. She also enjoys watching recreational activities on the lake, and feels that approval of the ERP will devalue her lakefront property. Ms. Benoit appeared at the first day of the hearing, but offered no testimony on her behalf. J. Christy Wilson, Esquire, appeared prior to the final hearing as counsel of record for Petitioners, Steven E. Larimer, Kathleen Larimer, and Helen Rose Farrow. Neither Ms. Wilson nor any of the three Petitioners she represented appeared at any time during the hearing, filed any pleadings seeking to excuse themselves from appearing at the final hearing, or offered any evidence, testimony, pre- or post- hearing submittals. Petitioner, Gary Jensen, did not appear at hearing, did not file any pleadings or papers seeking to be excused from appearing at the final hearing, and did not offer any evidence, testimony, pre- or post-hearing submittals. Both the City and the District recognize that areas downstream from the project site, such as Stone Island and Sanford, have experienced flooding in the past in time of high amounts of rainfall. The system proposed by the City for this ERP will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel. So long as the overflow structures are closed, the system will mimic pre-construction flow patterns, with no increase in volume flowing downstream. The District has considered the environment in its proposed approval of the ERP. The area abutting the project is little urbanized and provides good aquatic and emergent marsh habitat. With the exception of the western shore area of the deepwater marsh ("west marsh area"), the bay swamp and remaining deepwater marsh area have good ecological value. In the 1940's, the west marsh area was incorporated into the drainage system of a poultry farm that occupied the site. This area apparently suffered increased nutrient influxes and sedimentation that contributed to a proliferation of floating mats of aquatic plants and organic debris. These tussocks reduced the deepwater marsh's open water and diminished the historical marsh habitat. Water under the tussocks is typically anoxic owing to total shading by tussocks and reduced water circulation. Thick, soft, anaerobic muck has accumulated under the matted vegetation. Exotic shrubs (primrose willow Ludwigia peruvania) and other plants (cattails Typha spp.) dominate the tussocks. The construction of the project, from the 2003 Emergency Order, resulted in adverse impacts to 1.3 acres of wetlands having moderately high- to high ecological value and 0.2 acres of other surface waters. The 0.2 acre impact to other surface waters was to the lake bottom and the shoreline of Lake Doyle where the weir structure was installed. The 0.3 acres of wetland impacts occurred at the upper end of the deepwater marsh where the pipe was installed. The largest wetland impact (1.0 acre) was to the bay swamp. The bay swamp is a shallow body dominated by low hummocks and pools connected inefficiently by shallow braided channels and one acre is filled with a 1-2 foot layer of sediment following swamp channelization. Disturbance plants (e.g., primrose willow, Ludwigia peruvania, and elderberry Sambucus Canadensis) now colonize the sediment plume. Pursuant to the District's elimination and reduction criteria, the applicant must implement practicable design modifications, which would reduce or eliminate adverse impacts to wetlands and other surface waters. A proposed modification, which is not technically capable of being done, is not economically viable, or which adversely affects public safety through endangerment of lives or property is not considered "practicable." The City reduced and/or eliminated the impacts to the lake bottom and shoreline of Lake Doyle and deepwater marsh, to the extent practicable. The impacts were the minimum necessary to install the weir structure and pipe for the system; the weir structure and pipe were carefully installed on the edges of the wetland and surface water systems, resulting in a minimum amount of grading and disturbance. To compensate for the loss of 1.3 acres of wetlands and 0.2 acres of other surface waters, the City proposes to preserve a total of 27.5 acres of wetlands, bay swamp, marsh, and contiguous uplands. Included in this 27.5 acres are 6.4 acres of the west marsh, which are to be restored. The parties stipulated that the mitigation plan would adequately compensate for losses of ecological function (e.g. wildlife habitat and biodiversity, etc.) resulting from the project. Water quality is a concern for the District. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies for nitrogen, phosphorous, and dissolved oxygen. Water quality data for Lake Monroe indicate the lake has experienced high levels of nitrogen and phosphorous and low levels of dissolved oxygen. Prior to construction of the project, there was no natural outfall from the Lake Theresa Basin to Lake Monroe and therefore no contribution from this basin to nitrogen and phosphorous loadings to Lake Monroe. Lake Colby, Three Island Lakes (a/k/a Lake Sixma), and the Savannah are surface waters within the Lake Theresa Basin for which minimum levels have been adopted pursuant to Florida Administrative Code Chapter 40C-8. The system will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel, resulting in no outfall from the Theresa Basin to Lake Monroe. Minimum flows established for surface waters within the Lake Theresa Basin will not be adversely impacted. Under the first part of the secondary impact test, the City must provide reasonable assurance that the secondary impacts from construction, alteration, and intended or reasonable expected use of the project will not adversely affect the functions of adjacent wetlands or surface waters. The system is designed as a low intensity project. As proposed, little activity and maintenance are expected in the project site area. The reasonably expected use of the system will not cause adverse impacts to the functions of the wetlands and other surface waters. None of the wetland areas adjacent to uplands are used by listed species for nesting or denning. In its pre-construction state, the project area did not cause or contribute to state water quality violations. Under the second part of the secondary impact test, the City must provide reasonable assurance that the construction, alteration, and intended or reasonably expected uses of the system will not adversely affect the ecological value of the uplands to aquatic or wetland dependent species for enabling existing nesting or denning by these species. There are no listed threatened or endangered species within the project site area. Under the third part of the secondary impact test, and as part of the public interest test, the District must consider any other relevant activities that are closely linked and causally related to any proposed dredging or filling which will cause impacts to significant historical and archaeological resources. When making this determination, the District is required, by rule, to consult with the Division of Historical Resources. The Division of Historical Resources indicated that no historical or archaeological resources are likely present on the site. No impacts to significant historical and archaeological resources are expected. Under the fourth part of the secondary impact test, the City must demonstrate that certain additional activities and future phases of a project will not result in adverse impacts to the functions of wetlands or water quality violations. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the level in Lake Doyle rises above an elevation of 24.5 feet. Based upon the plans and calculations submitted, the proposed future phase, without additional measures, could result in minor increases in the loadings of nitrogen and phosphorous to Lake Monroe. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies due to water quality data indicating the lake has experienced high levels of nitrogen and phosphorous, and low levels of dissolved oxygen. Under this potential future phase, there would be an outfall from the Lake Theresa Basin to Lake Monroe. To address the impact on water quality of this potential future phase, the City has submitted a loading reduction plan for nitrogen, phosphorous, and dissolved oxygen. The plan includes compensating treatment to fully offset the potential increased nutrient loadings to Lake Monroe. Specifically, the loading reduction plan includes: Construction and operation of compensating treatment systems to fully offset anticipated increased nutrient loadings to Lake Monroe. Weekly water quality monitoring of the discharge from Lake Doyle for total phosphorous and total nitrogen. A requirement that the overflow structure be closed if the total phosphorous level reaches 0.18 mg/l or higher or the total nitrogen level reaches 1.2 mg/l or higher in any given week and will remain closed until levels fall below those limits. The implementation of these water quality mitigation measures will result in a net improvement of the water quality in Lake Monroe for nitrogen, phosphorous, or dissolved oxygen. The future phase was conceptually evaluated by the District for impacts to wetland functions. The future phase as proposed could result in adverse impacts to wetland functions. Operation of the system with the overflow structures open could impact the bay swamp and deepwater marsh. The City has demonstrated that any adverse impacts could be offset through mitigation. Based upon the information provided by the City and general engineering principles, the system is capable of functioning as proposed. The City of Deltona will be responsible for the operation, maintenance, and repair of the surface waster management system. A local government is an acceptable operation and maintenance entity under District rules. The public interest test has seven criteria. The public interest test requires the District to evaluate only those parts of the project actually located in, on, or over surface waters or wetlands, to determine whether a factor is positive, neutral, or negative, and then to balance these factors against each other. The seven factors are as follows: the public health, safety, or welfare of others; conservation of fish and wildlife and their habitats; fishing, recreational value, and marine productivity; temporary or permanent nature; 5) navigation, water flow, erosion, and shoaling; 6) the current condition and relative value of functions; and 7) historical and archaeological resources. There are no identified environmental hazards or improvements to public health and safety. The District does not consider impacts to property values. To offset any adverse impacts to fish and wildlife and their habitats, the City has proposed mitigation. The areas of the project in, on, or over wetlands do not provide recreational opportunities. Construction and operation of the project located in, on, or over wetlands will be permanent in nature. Construction and operation of the project located in, on, or over wetlands will not cause shoaling, and does not provide navigational opportunities. The mitigation will offset the relative value of functions performed by areas affected by the proposed project. No historical or archaeological resources are likely on the site of the project. The mitigation of the project is located within the same drainage basin as the project and offsets the adverse impacts. The project is not expected to cause unacceptable cumulative impacts.
Recommendation Based upon the Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered granting the City of Deltona's application for an environmental resource permit with the conditions set forth in the Technical Staff Report, and dismissing the Petitions for Formal Administrative Hearing filed by Gary Jensen in Case No. 04-2405, and by Steven E.

The Issue Whether a consumptive-use permit for quantities of water as applied for should be granted.
Findings Of Fact Applicant applied for a permit for a public supply of water from two (2) wells to accommodate 3,100 family units in Hillsborough County, Florida. Each well to be 500 feet deep and designated as "new use", i.e., a use not existing prior to January 1, 1975. Well "No. 1" would draw 72,000 gallons per day and well "No. 2", 682,000 gallons per day. The center of withdrawal is located at latitude 28 degrees 6' 18" North, longitude 82 degrees 29' 48" West in Hillsborough County, Florida. The applicant lists 802.2 acres as being owned, leased or otherwise controlled by it. Notice was published in a newspaper of general circulation, to-wit: The Tampa Tribune on April 28 and May 5, 1975, pursuant to Section 373.146, Florida Statutes. Notices of said public hearing were sent by certified mail to Lorenzo Lakes, A Joint Venture, Route 2, Box 737A, Lutz, Florida, and Hillsborough Dairy, Route 1, Box 115, Tampa, Florida A letter was received although it was not designated a letter of objection. The author of said letter is present at this hearing. His name is Mr. John Logan, Water Resources Director, Hillsborough County, Florida. The letter suggests that action on the subject application would be inappropriate at this time inasmuch as a part of the development is to be deeded to Hillsborough County for public roadways. A specific area does not appear to be established but it may exceed 50 acres. Additional acreage may be needed for flood easements for the extension of channel "F", a proposed part of the upper Tampa Bay Watershed Project. No formal letters of objection were received. The following exhibits were introduced without objection: Application for permit Proof of publication Letter from Mr. John Logan The witnesses were duly sworn and agreement by the parties reached on each point to be considered under Chapter 373, Florida Statutes, and the Rules and Regulations promulgated pursuant thereto, particularly Rule 16J-2.11, with the exception that certain conditions were recommended by Mr. George Szell, Hydrologist for the Permittee, and said conditions were agreed to by the Permittee. Mrs. Sally Casper appeared as a member of the public questioning the need for new housing and objecting in essence to Rule 16J-2.11(2)(e) which restricts consideration of lake stages or vegetation to those not controlled by the applicant. Upon the request of the Hearing Officer the parties agreed to enter into a joint order of stipulation and submit said order to the Hearing Officer. Said stipulation was received by the Hearing Officer on July 7, 1975, and is attached hereto and made a part hereof and marked "Supplement to Record".
The Issue The central issue in this case is whether the Department of Environmental Regulation (Department) should grant a dredge and fill permit which has been requested by the Respondent, William R. Cullen (Applicant). That proposed permit has been opposed by the Petitioners (who will be referred to collectively as Petitioners for convenience sake).
Findings Of Fact Based upon the testimony of the witnesses and the documentary evidence received, the following findings of fact are made: The Department is the state agency authorized to issue permits pursuant to Chapter 403, Florida Statutes. The Respondent, William R. Cullen, filed an application for a dredge and fill permit to construct a slip marina on June 4, 1985. The original request was subsequently amended to seek approval for a forty-two slip commercial marina. The project site for the Applicant's marina is located at Key Largo, Monroe County, Florida. The site is within Buttonwood Sound, Florida Bay. The property is owned by Mr. Cullen and his family. All of the proposed improvements will be constructed on submerged lands or uplands owned or controlled by the Cullen family. The project site is located within a commercial area of Key Largo and contains frontage on both the water, Buttonwood Sound, and the highway, U.S. Highway 1. The project site has a basin which was created by the excavation of materials used for road construction from the shoreline and the installation of an L-shaped rock jetty which runs roughly perpendicular and then parallel to the shoreline. This jetty was installed during the late 1960s. The water depths within the basin range from 3 feet to approximately 14 feet. The water within the basin is subject to the same tidal considerations as the waters within Buttonwood Sound. There is no interruption of the flow of water in and out of the basin from those waters of the Sound. The water within this basin is within an Outstanding Florida Water as defined in Rule 17-3.041, Florida Administrative Code. The Applicant's plan calls for the excavation of appproximately 30,170 square feet of upland area and the dredging of the existing basin for approximately 18,460 dredged square feet. During the construction phases, the Applicant proposes to install turbidity curtains to limit the adverse effects expected during that time. The improvements are intended to be a permanent alteration to the basin design and will permanently modify the marine life habitat within that basin. The Applicant proposes to remove portions of the existing jetty to allow additional water to flow through the basin unimpeded by the jetty walls. The removal of the jetty walls will expedite the dilution and flushing of potential pollutants from the basin on a tidal frequency. That flushing is purported to assure that the water quality within the basin will not be diminished. However, such pollutants will be flushed into Buttonwood Sound. Stormwater accumulating on the upland project is to flow toward a lower upland area and should not to be dumped into the basin. The proposed marina is to have fueling facilities and the Applicant has agreed to design that system to limit inadvertent spillage. Further, as a condition of the permit, the Applicant has agreed to abide by the Department of Natural Resources' spill contingency plan requirements. The proposed marina is designed to provide portable sewage pumpout facilities for each slip. A permanent pumpout facilities will also be available. The Applicant seeks to attract boats in the range of 30 to 50 feet in length at this facility. While there are a number of other marinas in other areas of Key Largo which might accomodate that size boat, the marinas in the immediate vicinity of this project site are designed for smaller craft. The area within the basin consists of unvegetated bottom, submerged rip-rap, sea grasses, and hardbottom/algae communities--the predominant classifications being the latter two. The deeper hardbottom areas are to be filled and portions of the sea grasses will be dredged in order to configure the proposed docks. Additionally, other sea grass areas will be shaded, and thereby disturbed, by the construction of the docks. There are no historical or archaeological features relevant to the proposed site. The area has not been designated as a critical manatee area, however, manatees do frequent the project vicinity and have been observed feeding immediately adjacent to the basin. The permit proposed for this project requires a water quality monitoring plan. In addition to sampling for coliform, diesel by-products, oils, greases, detergents, oxygen, copper, lead and zinc, the plan requires sampling for aluminum, cadmium, and chromium. The monitoring stations are to be located both within the basin (2 stations) and outside the basin (2 stations). Liveaboards or others continuously docked at the marina will create additional shading which will disrupt and adversely affect the sea grass system. In order to provide access to the marina, the Applicant intends to dredge a channel in an area containing sea grass which is undisputedly within the Outstanding Florida Waters. The Department deemed the subject application was complete on February 23, 1988. The Department did not apply the Keys Rule found in Rule 17-312.400, Florida Administrative Code, to this project. The Department also did not apply the Mitigation Rule found in Rule 17-312.300, Florida Administrative Code, to this project. Michael Dentzau has personally reviewed and processed 250-300 dredge and fill permits during his tenure with the Department. Of those projects he has reviewed, he has not recommended that dense sea grass beds of the type located within this project site be dredged in order to construct a commercial marina. Phillip Edwards was responsible for executing the Intent to Issue in this case. In determining that this project had provided reasonable assurances that water quality standards will not be violated, Mr. Edwards weighed the public interests criteria set forth in Section 403.918, Florida Statutes. Because he received letters purportedly from elected officials, Mr. Edwards presumed that the project was in the public interest. That assumption of fact has not been established by this record. According to Mr. Edwards, the adverse effects expected by this project could be adequately addressed by the permit conditions when weighed against the public interest in favor of the project. Since Mr. Edwards' assumptions as to the public interest in this project have not been established, his conclusion regarding the weight that interest should receive can be given little consideration. The project as proposed by the Applicant will not adversely affect navigation or cause harmful erosion or shoaling. The project as proposed by the Applicant will adversely affect fishing or marine productivity within the basin since it will permanently alter the basin biologically by destroying sea grass. The increased boat traffic within the Sound will also detract from the present recreational uses enjoyed by area residents. According to Mr. Edwards, it is very unusual for the Department to issue a permit when sea grasses will be adversely affected. In the 17 years in which he has reviewed permits, only two occasions merited approval when the destruction of sea grasses to the extent in this case would result. Neither of those cases were factually similar to the case at issue. In those cases, however, elected officials advised Mr. Edwards, as he presumed they had here, that there was a public need for the permit. Increased boat traffic will result in increased manatee mortality due to collisions. In order to assure water quality will not be degraded within a marina, the project should have a short flushing time comparable to healthy natural embayments. In this case, the flushing proposed by the Applicant is dependent, in part, on winds which may be inconsistent or relatively minimal during the summer months.
Recommendation Based on the foregoing, it is RECOMMENDED: That the Department of Environmental Regulation enter a final order denying the permit requested by the Applicant.

The Issue Whether a consumptive use permit for the quantities of water as applied for should be granted.
Findings Of Fact Application No. 7500112 requested water from three (3) wells for the purpose of industrial use. This application is for a new use. The center of withdrawals will be located at Latitude 27 degrees 38' 58" North, Longitude 81 degrees 48' 21" West, in Hardee County, Florida. The application is for the use of not more than 470 million gallons of water per year and not more than 2,592,000 gallons of water during any single day to be withdrawn from the Florida Aquifer. Application received as Exhibit 1. Notice was published in a newspaper of general circulation, to-wit: The Herald Advocate, published weekly in Wauchula, Florida, on August 7 and 14, 1975, pursuant to Section 373.146, Florida Statutes. Notices of said public hearing were duly sent by certified mail as required by law. The affidavit of publication was received without objection and entered into evidence as Exhibit 2. Letters of objection were received from the following: Mr. Joseph F. Smith, Route 1, Box 238, Wauchula, Florida 33273. Mr. Smith states that in his opinion such withdrawal of water will severely damage his property. He is developing a mobile home park on eight (8) acres and is fearful that the amount of water requested in this application will diminish his supply of water for his project. A letter from Mr. and Mrs. A. H. Van Dyck, written on August 16, 1975, Route 2, Box 657, Wauchula, Florida 33873. They are fearful that the large amount of water American Orange Corporation proposes to pump each day will affect their shallow well which provides water for their home. They would like to see some type of agreement whereby American Orange Corporation would be willing to pay for replacement of the well if the corporation should cause their well to go dry. Mr. Stanley H. Beck, Counselor at Law, wrote a letter in behalf of his client, Harold Beck, requesting information as to the applicable statutes and regulations which affect the matter of the consumptive use permit. A telegram was sent by Harold Beck of Suite 1021, Rivergate Plaza, Miami 33131, stating that he objected to the application of American Orange Corporation's withdrawal of water or the reason that it would reduce the property value. The witness for the permittee is Barbara Boatwright, hydrologist, who was duly sworn and agreement was reached on each point enumerated as required by Rule 16J-2.11, Rules of the Southwest Florida Water Management District and Chapter 373, Florida Statutes. The staff hydrologist recommended that the permit be granted with two (2) conditions. One was that each of the wells be metered and two, that the District receive monthly reports from each meter. The applicant has consented.
The Issue The issue is whether the District should approve Environmental Resource Permit No. 43024788.002 for the construction of a surface water management system to serve the proposed residential subdivision on Westfield’s property in southern Pasco County, and based upon the prior litigation between the parties in DOAH Case No. 04-0003 and the pre-hearing rulings in this case, the issue turns on whether Westfield has provided “reasonable assurances” in relation to the proposed development's potential impacts on Wetland A3 and fish and wildlife.
Findings Of Fact Parties Dr. Blanco is a veterinarian. He grew up on, and has some sort of ownership interest in the property (hereafter “the Blanco property”) immediately to the west of the property on which the proposed development at issue in this case will occur. Dr. Blanco is particularly concerned about the impacts of the proposed development on the ecological health of Wetland A3, a significant portion of which is on the Blanco property. He has spent considerable time over the years observing and enjoying that wetland. Westfield is the applicant for the ERP at issue in this case, and it owns the property (hereafter “the Westfield property”) on which the development authorized by the ERP will occur. The District is the administrative agency responsible for the conservation, protection, management, and control of the water resources within its geographic boundaries pursuant to Chapter 373, Florida Statutes, and Florida Administrative Code Chapter 40D. Among other things, the District is responsible for reviewing and taking final agency action on ERP applications for projects within its boundaries. The District includes all or part of 16 counties in southwest Florida, including Pasco County. The Proposed Development (1) Generally The Westfield property consists of 266.36 acres.3 It is located in southern Pasco County on the north side of State Road 54, approximately three miles west of U.S. Highway 41 and less than one-half mile east of the intersection of State Road 54 and the Suncoast Parkway. The Westfield property is bordered on the south by State Road 54,4 on the north by an abandoned railroad right-of- way and undeveloped woodland property, on the east by pastureland and property that has been cleared for development, and on the west by the Blanco property. The development proposed for the Westfield property is a residential subdivision with 437 single-family lots and related infrastructure (hereafter “the Project” or “the proposed development”). The ERP at issue in this proceeding is for the surface water management system necessary to serve the Project. There are 19 isolated and contiguous wetlands on the Westfield property, including Wetland A3, which is partially on the Westfield property and partially on the Blanco property. Wetlands cover 72.69 acres (or 27.3 percent) of the Westfield property. The proposed development will result in 1.61 acres of the existing wetlands -- Wetlands B4 and C4, and a portion of Wetland B12 -- being permanently destroyed. The remaining 71.08 acres of existing wetlands will be preserved. Wetlands B4 and C4 are small (each less than 0.75 acres), shallow, wet depressions in a pasture that have been significantly impacted by livestock grazing and periodic mowing. Wetland B12 is a low-quality, small (0.58 acres), isolated, forested wetland that has been impacted by livestock grazing and the intrusion of exotic species. The proposed development will create 2.89 acres of new wetlands, which means that the Project will result in a net gain of 1.28 acres of wetlands. The created wetlands, referred to as Wetland B2 or the “mitigation area,” are in the northern portion of the property along the abandoned railroad right-of-way and to the east of Wetland A3. The proposed ERP includes a number of special conditions, Nos. 6 through 11, related to the mitigation area. Among other things, the conditions require monitoring of the mitigation area to ensure that it develops into the type of forested wetland proposed in the ERP application. (2) Prior ERP Application The ERP at issue in this case is the second ERP sought by Westfield for the Project. The first ERP, No. 43024788.000, was ultimately denied by the District through the Final Order in Blanco-I. Blanco-I, like this case, was initiated by Dr. Blanco in response to the District’s preliminary approval of Westfield’s ERP application. Administrative Law Judge David Maloney held a three- day final hearing in Blanco-I at which the parties, through counsel, fully litigated the issue of whether Westfield satisfied the regulatory criteria for the issuance of an ERP for the proposed development. On December 17, 2004, Judge Maloney issued a comprehensive, 64-page Recommended Order in which he recommended that Westfield’s ERP application be denied. Judge Maloney determined in his Recommended Order that Westfield failed to provide reasonable assurances as required by the applicable statutes and rules because “[1] it omitted an adequate wildlife survey from the submission of information to the District and [2] it failed to account for seepage from Pond P11 and its effect on Wetland A3 and the Cypress-forested Wetland.”5 In all other respects, Judge Maloney determined that the applicable permit requirements had been satisfied. Dr. Blanco did not file any exceptions to the Recommended Order in Blanco-I. Westfield’s exceptions to the Recommended Order in Blanco-I were rejected by the District, and the Recommended Order was adopted “in its entirety” in the District’s Final Order. The Final Order in Blanco-I was rendered on January 27, 2005, and was not appealed. (3) Current ERP Application On April 29, 2005, approximately three months after the Final Order in Blanco-I, Westfield submitted a new ERP application for the Project. The current ERP application, No. 43024788.002, is identical to the application at issue in Blanco-I, except that the depth of Pond P11 was reduced in certain areas from a maximum of approximately 25 feet to a maximum of approximately 12 feet, an analysis of the potential impact of Pond P11 on Wetland A3 resulting from “seepage” was included with the application, and additional wildlife surveys were included with the application. On July 29, 2005, the District gave notice of its preliminarily approval of the current ERP application. The notice was accompanied by a proposed ERP, which contained a description of the Project as well as the general and special conditions imposed by the District. On August 24, 2005, Dr. Blanco timely challenged the District’s preliminary approval of the current ERP application. The Request for Administrative Hearing filed by Dr. Blanco in this case is identical to the request that he filed in Blanco-I. Disputed Issues Related to the Current ERP Application Impact of Pond P11 on Wetland A3 Dr. Blanco’s primary objection to the Project is the excavation of Pond P11 adjacent to Wetland A3. Wetland A3 is on the western border of the Westfield property and, as noted above, the wetland extends onto the Blanco property. The portion of Wetland A3 that is on the Westfield property is approximately 30 acres, and the portion of the wetland on the Blanco property appears to be slightly larger. Wetland A3 is a large, mature, Cypress-forested wetland. It has been impacted by nearby development and is not a pristine wetland, but it is still a mid to high quality wetland for the area.6 Wetland A3 is part of a larger wetland system that extends northward and westward beyond the abandoned railroad right-of-way that serves as the northern boundary of the Westfield and Blanco properties. Cypress-forested wetlands, such as Wetland A3, are very tolerant of prolonged periods of drought and inundation. The seasonal high groundwater level in Wetland A3 is approximately one foot below the surface in most areas of the wetland. There are, however, areas in Wetland A3 in which water is frequently a foot or two above the surface. The groundwater levels in Wetland A3 have, in the past, been significantly impacted by drawdowns in the aquifer caused by pumping in nearby wellfields. The impact has been less significant in recent years as a result of the reductions in pumping mandated by the Tampa Bay Consolidated Water Use Permit. The planned interconnection of several nearby wellfields is also expected to minimize the drawdowns in the aquifer and should further stabilize the groundwater levels in Wetland A3. Pond P11 will be located adjacent to Wetland A3. There will be a 25-foot buffer between the pond and the wetland. The location of Pond P11 is unchanged from the first ERP application. Pond P11 will have a surface area of approximately 37 acres. The surface area of Pond P11 is unchanged from the first ERP application. Pond P11 is a necessary component of the surface water management system for the Project. It also serves as a “borrow pit” because the soil excavated from the pond will be used on- site as fill for the proposed development. The excavation of Pond P11 to the depth proposed in the current ERP application is not necessary for water storage. The pond could be excavated to the seasonal high water level -- approximately 2.5 feet deep -- and still function as intended as part of the proposed surface water management system. Pond P11 will be used for attenuation, but the pond is also expected to provide at least some amount of water quality treatment, which is an added benefit to Wetland A3 into which the proposed surface water management system will ultimately discharge through Pond P11. The only change made to Pond P11 between the first and current ERP applications was a reduction in the pond’s maximum depth. The pond, which had a maximum depth of approximately 25 feet in the first ERP application, was “shallowed up” in the current ERP application. Pond P11 will now be approximately 12-feet deep at its deepest point, unless the District authorizes excavation to a greater depth in accordance with special condition No. 28. The shallowest area of Pond P11 will be along the western edge of the pond adjacent to Wetland A3 where there will be an expansive “littoral shelf” that will have almost no slope and that will be excavated only to the seasonal high water level.7 There was no change in the design of the surface water management system between the first ERP application and the current ERP application. The reduction in the depth of Pond P11 will have no impact on the operation of the system, which was described in detail in Blanco-I.8 Pond P11 will have a control structure to allow water to be discharged into Wetland A3 near its southern end, which is a more upstream location than water is currently discharged as a result of the ditches that intercept surface water flowing across the Westfield property. This design feature of the surface water management system is intended to mimic historic hydrologic conditions and is expected to increase the hydration of Wetland A3. The ERP includes a special condition, No. 28, relating to the excavation of Pond P11. The condition provides: Maximum depth of excavation will be +38 feet NGVD[9] unless additional field observations and data are provided that support excavation to greater depth, subject to review and approval by District staff. Proposed maximum depths of excavation . . . may be exceeded based upon field observations and approval as specified. Due to the potentially irregular depths to limestone, excavation will be stopped at a shallower depth if confining soils are encountered before reaching the maximum depth specified in Subcondition A, above. A geotechnical field technician will be present on site during the entire excavation process in order to monitor excavated soils. The field technician will be under the supervision of a Professional Geologist or Professional Engineer. For the purposes of the specific project, confining soils are defined as soils with more then 20 percent fines passing a No. 200 sieve. The field technician will be authorized to halt depth of excavation when confining soils are encountered. Excavation may proceed deeper than soils containing 20 percent or more fines if the soils are shown to be an isolated lens of material significantly above underlying confining soils or limestone, as determined by field observations and data subject to approval by District staff. Confining soils do not uniformly overlie the limestone; therefore it is possible that the underlying limestone could be encountered in spite of precautions in Subconditions A and B above. If the underlying limestone is encountered, excavation will be halted in the area of exposed underlying limestone. The area of exposed limestone will be backfilled to a minimum depth of two feet with compacted material meeting the specification of confining soils, having more than 20 percent fines passing a No. 200 sieve. The geotechnical field technician must certify that the backfill material meets this specification. One of the reasons that the ERP application was denied in Blanco-I was that Westfield failed to take into account the potential hydrologic impacts on Wetland A3 caused by “seepage” of water from Pond P11 due to the depth to which the pond was to be excavated and the corresponding removal of the confining layer of soils between the bottom of the pond and the aquifer. After Blanco-I, Westfield retained Marty Sullivan, a professional engineer and an expert in geotechnical engineering and groundwater and surface water modeling, to evaluate the seepage issue and the potential hydrologic impacts of Pond P11 on Wetland A3. Mr. Sullivan developed an integrated or “coupled” groundwater/surface water model to assess these issues. The model was designed to project the change in groundwater levels caused by the proposed development more so than absolute groundwater levels. The model utilized a widely-accepted computer program and incorporated data from topographic and soil survey information maintained by the U.S. Geologic Service; data from soil borings performed on the Westfield property in the vicinity of Wetland A3 in the area where Pond P11 will be located; data from groundwater monitoring wells and piezometers installed around the Westfield property; data from soil permeability tests performed on-site and in the laboratory; data from a rain gauge installed on the Westfield property; and data from the District’s groundwater monitoring wells in the vicinity of the Westfield property. Mr. Sullivan “calibrated” the model based upon known pre-development conditions. He then “ran” the model with the data from the Interconnected Pond Routing (ICPR) model10 used to design of the surface water management system in order to project the post-development groundwater conditions over a simulated ten-year period. Mr. Sullivan’s coupled groundwater/surface water model addresses the shortcoming of the ICPR model set forth in Blanco- I.11 The model projects that the post-development groundwater levels at the western boundary of the Westfield property in Wetland A3 adjacent to Pond P11 will be the same as the pre-development levels during the “wet season” of June to September, and that, on average and during the “dry season” of October to May, the post-development groundwater levels will be 0.3 feet higher than the pre-development levels. Mr. Sullivan summarized his conclusions based upon these projections in a report provided to the District with the current ERP application. The report states that: no adverse hydrologic effects will result from the excavation of Pond P11 and the development of the surrounding area. Particularly, Wetland A3 will be essentially unaffected and will be slightly enhanced by this development. Some additional hydration of wetland A3 will occur due to eliminating the north-south drainage ditch and instead routing runoff to Pond P11, which is adjacent to Wetland A3. The relative differences in the pre- and post- development levels are more important than the absolute levels projected by the model and, in this case, there is almost no difference in the levels. The minimal change in the water levels expected in Wetland A3 will not affect the wetland’s ecological functioning or its viability. A 0.3-foot change in the water level is well within the normal range of hydroperiod fluctuation for Wetland A3. The rate at which water increases and decreases in a wetland can impact wetland ecology and wetland-dependent species. The proposed surface water management system will not increase the surface water discharges from the Westfield property, and in compliance with Section 4.2 of the Basis of Review (BOR),12 the post-development discharge rates will not exceed the pre-development peak discharge rates. There is no credible evidence that there will be an adverse impact on Wetland A3 caused by changes in the discharge rate from the Westfield property through Pond P11 into Wetland A3. The range of error, if any, in Mr. Sullivan’s model is unknown. He has never performed a post-development review to determine how accurately the model predicts the post-development conditions that are actually observed. Nevertheless, the more persuasive evidence establishes that Mr. Sullivan’s model is reasonable, as are his ultimate conclusions based upon the model’s projections. Mr. Sullivan recommended in his report that Pond P11 be excavated no deeper than two feet above the limestone to avoid potential breaches of the confining soils above the aquifer. That recommendation led to the pond being “shallowed up,” and it was incorporated by the District into special condition No. 28. The provisions of special condition No. 28 are reasonable to ensure that excavation of Pond P11 will not breach the confining layer. The standards in special condition No. 28 pursuant to which a geotechnical field technician will monitor the excavation of Pond P11, and pursuant to which the District will determine whether to authorize deeper excavation of the pond, are generally accepted and can be adequately monitored by professionals in the field and the District. There is a potential for the loss of “significant volumes of water” from Pond P11 through evaporation “[d]ue to the sheer size of P11’s open surface area.”13 It is not entirely clear how the evaporation of water from Pond P11 was taken into account in Mr. Sullivan’s model, but it appears to have been considered.14 Dr. Mark Rains, Petitioner’s expert in hydrogeology, ecohydrology, and geomorphology, testified that evaporation from open water is generally about 12 inches more per year than evaporation from a wet meadow or Cypress forest, but he did not offer any specific criticism of the projections in Mr. Sullivan’s model related to the issue of evaporation. In sum, the more persuasive evidence establishes that Wetland A3 is not likely to suffer any adverse ecological or hydrological impacts from the proposed surface water management system and, more particularly, from Pond P11. Westfield has provided reasonable assurances in that regard. (2) Adequacy of the Wildlife Surveys The other reason why the first ERP application for the Project was denied in Blanco-I was that the wildlife surveys submitted with that application were found to be inadequate. Wildlife surveys are not required with every ERP application and, in that regard, Section 3.2.2 of the BOR provides that: [t]he need for a wildlife survey will depend on the likelihood that the site is used by listed species, considering site characteristics and the range and habitat needs of such species, and whether the proposed system will impact that use such that the criteria in subsection 3.2.2 through 3.2.2.3 and subsection 3.2.7 will not be met. Westfield conducted a “preliminary” wildlife assessment in 2001. No listed species were observed, nor was any evidence of their presence on the Westfield property. Nevertheless, as detailed in Blanco-I,15 the District requested that Westfield perform a wildlife survey of Wetlands B4, C4, and B12, because all or part of those wetlands will be permanently destroyed by the proposed development. In an effort to comply with the District’s requests, Westfield conducted additional field visits in 2003 and also performed specific surveys for Southeastern Kestrels and Gopher Tortoises. The field visits “confirmed” the findings from the preliminary wildlife assessment, and no evidence of Southeastern Kestrels and Gopher Tortoises was observed during the surveys for those species. Judge Maloney found in Blanco-I that the wildlife surveys conducted by Westfield were inadequate because they “did not employ the methodology recommended by the District: the FWCC methodology.”16 However, the wildlife surveys were not found to be inadequate in Blanco-I because they focused on Wetlands B4, C4, and B12, instead of evaluating the entire Westfield property and/or all of the potentially impacted wetlands, including Wetland A3. After Blanco-I, a team of qualified professionals led by Brian Skidmore, an expert in wetlands, Florida wetlands ecology, and listed species assessment, conducted additional wildlife surveys of the Westfield property. Mr. Skidmore and his team had performed the preliminary wildlife assessment and the supplemental surveys submitted with Westfield’s first ERP application. The “FWCC methodology” referenced in Blanco-I is a methodology developed by the Fish and Wildlife Conservation Commission (FWCC) to evaluate potential impacts to listed species from large-scale projects, such as developments-of- regional impact and new highways. It is not specifically designed for use in the ERP process, which focuses only on wetland-dependent species. Mr. Skidmore adapted the FWCC methodology for use in the ERP process. The methodology used by Mr. Skidmore was reviewed and accepted by the District’s environmental regulation manager, Leonard Bartos, who is an expert in wetland ecology and ERP rules. The surveys performed by Mr. Skidmore and his team of professionals occurred over a five-day period in February 2005. The surveys focused on Wetlands B4, C4, and B12, and were performed at dawn and dusk when wildlife is typically most active. Additional wildlife surveys of the entire site were performed on five separate days between October 2005 and January 2006. Those surveys were also performed at dawn and dusk, and they included observations along the perimeter of Wetland A3 and into portions of the interior of that wetland on the Westfield property. Mr. Skidmore reviewed databases maintained by FWCC to determine whether there are any documented waterbird colonies or Bald Eagle nests in the vicinity of the Project. There are none. Mr. Skidmore contacted the Florida Natural Area Inventory to determine whether there are any documented rare plant or animal species on the Westfield property or in the vicinity of the Project. There are none. The post-Blanco-I wildlife surveys did not evaluate the usage of the Westfield property by listed species during the wetter spring and summer months of March through October even though, as Mr. Skidmore acknowledged in his testimony, it is possible that different species may use the property during the wet season. The post-Blanco-I wildlife surveys, like the original wildlife surveys, focused primarily on the species contained in Appendix 5 to the BOR -- i.e., wetland-dependent species that use uplands for nesting, foraging, or denning -- but Mr. Skidmore testified that he and his surveyors “were observant for any species,” including wetland-dependent species that do not utilize uplands. No listed wetland-dependent species were observed nesting or denning on the Westfield property. Several listed wetland-dependent birds -- i.e., snowy egret, sandhill crane, wood stork, and white ibis -- were observed foraging and/or resting on the property. Those birds were not observed in Wetlands B4, C4, or B12. The parties stipulated at the final hearing that the determination as to whether Westfield provided reasonable assurances with respect to the statutory and rule criteria related to fish and wildlife turns on whether the wildlife surveys submitted by Westfield are adequate.17 BOR Section 3.2.2 provides that “[s]urvey methodologies employed to inventory the site must provide reasonable assurance regarding the presence or absence of the subject listed species.” The wildlife surveys conducted by Westfield subsequent to Blanco-I in accordance with the FWCC methodology meet this standard. Although the surveys could have been more extensive in terms of the species assessed and the period of time over which they were conducted, the more persuasive evidence establishes that the wildlife surveys are adequate to document the presence or, more accurately the absence of listed wetland- dependent species on the Westfield property. The wetlands that will be directly impacted by the proposed development -- Wetlands B4, C4, and B12 -- do not provide suitable habitat for listed species. Those wetlands are small, low-quality wetlands, and Wetland B12 is technically exempt from the District’s fish and wildlife review because it is a small isolated wetland. There is no credible evidence that there will be any other adverse impacts to fish and wildlife from the proposed surface water management system. For example, even if there are undocumented listed species -- e.g., frogs, snakes, snails, etc. -- in Wetland A3, Mr. Skidmore credibly testified that the expected 0.3-foot increase in groundwater levels in that wetland during the dry season is not likely to adversely affect those species or their habitat because the water will still be below the surface. In sum, Westfield has provided reasonable assurance that the proposed development will not adversely affect fish and wildlife.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the District issue a final order approving Environmental Resource Permit No. 43024788.002, subject to the general and special conditions set forth in the proposed ERP dated July 29, 2005. DONE AND ENTERED this 10th day of April, 2006, in Tallahassee, Leon County, Florida. S T. KENT WETHERELL, II Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 10th day of April, 2006.
The Issue The issue is whether to approve an application by Respondent, I.M. Collier, J.V. (Collier), to modify its Environmental Resource Permit (ERP) No. 11-02031P (2002 Permit) by changing the surface water management system (SWMS) for a proposed residential and golf course development in Collier County (County), Florida, known as Mirasol.
Findings Of Fact Based on the evidence presented by the parties, the following findings of fact are made: The Parties National Audubon Society, Inc. is a not-for-profit corporation (incorporated outside the State of Florida) while Collier County Audubon Society, Inc., Florida Wildlife Federation, and Conservancy of Southwest Florida are Florida not-for-profit corporations. All are environmental organizations. Franklin Adams is a resident of the County and a member of each of the above organizations. Respondents have not contested Petitioners' standing based upon the stipulated facts set forth in the parties' Pre-Hearing Stipulation. The District is a water management district with the power and duty to exercise regulatory jurisdiction over the administration and enforcement of ERP criteria pursuant to Chapter 373, Florida Statutes, and Florida Administrative Code Title 40E. Collier is the holder of the 2002 Permit authorizing the construction of a SWMS to serve the Mirasol project, a large development located in the County. The parties have stipulated that Collier has the administrative, legal, and financial capabilities to undertake the proposed activity. Fla. Admin. Code R. 40E-4.301(1)(j). The Project Site The Mirasol project consists of approximately 1,713.45 acres located on the north side of Immokalee Road and the Cocohatchee Canal (Canal) in the northern half of the County, approximately three miles east of the intersection with Interstate 75. The property spans three sections of land, the northern third of the property encompassing Section 10, the middle third encompassing Section 15, and the southern third encompassing most of Section 22. The site also includes a peninsula of land extending east of Section 10, encompassing the northernmost quarter of Section 11. The site is bounded on the south by the Canal and Immokalee Road and on the east by an existing residential development known as Heritage Bay, which was previously a rock- mining quarry. To the west of the site, running north to south, are two other proposed residential developments known as Parklands Collier and Terafina/Saturnia Falls and an existing residential and golf course community known as Olde Cypress. There are other existing and proposed residential developments and farm fields to the north of the site. The site is located southwest of the Corkscrew Swamp Sanctuary (Corkscrew Swamp), which is owned by the National Audubon Society, Inc., and appears to stretch from Immokalee (in the northeastern part of the County) south and southwestward through parts of the County. Corkscrew Swamp sits roughly at the center of a 315-mile watershed, much of which is comprised of short hydroperiod wetlands which dry down completely during the late winter and spring and become inundated again in the late summer and fall during the wet season. This water gradually sheet flows down a very slight downhill gradient toward the south and west. A portion of the sheet flow travels southwest in the vicinity of the site. The region has experienced occasional floods, the most severe of which occurred in 1995. At the direction of the District, the cause of the flooding was investigated in the South Lee County Watershed Study (Study), which concluded that the watershed discharges through a variety of outfalls, but that historic connections to downstream conveyances like the Canal were severed by the construction. While downstream conveyances exist, the Study concluded that connections between upstream flows and downstream conveyances should be enhanced or restored. In the late 1990s, the Canal was improved to increase its conveyance capacity. A berm was constructed by the Big Cypress Basin Board (Basin Board), a legislatively-created entity which manages water resources in the County, on the northern bank in the vicinity of, and across from, the Mirasol site. This berm prevented historic wet season sheet flow from reaching the Canal through the project site, except for a few culverts located along that water body. The Basin Board also built a 1,000-foot-long hardened concrete weir on the north side of the Canal a few thousand yards west of the project site. This weir provides the primary outlet for sheet flow in and around the Mirasol site. Currently, upstream drainage flows in a southwesterly direction across Section 10. As the water moves south to the Canal, the flow becomes constricted down to a 580-foot wide gap between the Olde Cypress residential development and commercial developments along Immokalee Road to the east. This constricted area further narrows to a 270-foot wide opening before the sheet flow reaches the 1,000-foot weir and discharges into the Canal. During a 3-day, 25-year storm event, a combined peak flow of 553 cubic feet per second (cfs) of water is discharged into the Canal through the 1,000-foot weir, but the Mirasol property only conveys a small portion of this water (around 20 cfs) through culverts in the Canal berm. Most of the water flows to the west of Mirasol where it passes through the narrow gap and over the 1,000-foot weir. Around 1,431 acres of the 1,714-acre site are jurisdictional wetlands. However, these wetlands are in poor condition due to existing impediments to sheet flow, artificially high water levels during the wet season, and heavy infestation of exotic species, principally melaleuca. Permit History In February 2002, the District issued the 2002 Permit approving the construction of a SWMS to serve two 18-hole golf courses, a single-family residential community, a golf course clubhouse and parking area, golf course maintenance facilities, sales facility, and parking area. The issuance of the 2002 Permit was not challenged. The SWMS included a 36.5-acre flow-way (Flow-Way) that encircled the northern boundary of the development in Section 15 and extended off-site and across adjacent properties to the west. (If constructed, the Flow-Way would be a 200-foot wide, 4-foot deep, 89-acre channel, more than half of which would have been located on the Saturnia Falls/Terafina and Olde Cypress properties.) Besides providing a conveyance function for the Mirasol site, the Flow-Way also enhanced flood protection for other properties by accelerating conveyance of floodwaters to the Canal and reducing peak flood stages by 0.4 feet during a three-day, 25-year storm event. The District included Special Condition 26 in the 2002 Permit, which required construction of the Flow-Way before the remainder of the project could be constructed. The 2002 Permit authorized Collier to directly impact (fill or excavate) 568.66 acres of wetlands within the footprint of the development. Additionally, 39.5 acres of wetlands, which were isolated remnant strips along the golf courses within the development, were considered secondarily impacted and assessed a thirty-three percent reduction in functional value. Mitigation for the project consisted of preservation and enhancement of wetlands and uplands on site. Enhancement of the preserve areas was primarily credited to the eradication of malaleuca and other exotic species and replanting with appropriate native vegetation. Permit conditions required management of the preserve areas to prevent a recurrence of exotic species. The preserve areas included an 846.95-acre external preserve area to the north and northeast of the area to be developed. It was anticipated that this northern preserve area would ultimately be donated to an existing mitigation area known as the Corkscrew Regional Ecosystem Watershed, along with an interest-bearing fund to ensure perpetual management. In December 2005, the United States Army Corps of Engineers (Corps) denied Collier's federal wetlands permit application for the project and the Flow-Way. Because of this denial, in May 2006 Collier submitted an ERP application with the District seeking to modify the 2002 Permit by revising the SWMS and removing the Flow-Way. On October 12, 2006, the District Governing Board approved a modification to the 2002 Permit, which authorized an alternate SWMS to serve the golf course and residential development (2006 Permit). Petitioners' challenge to the proposed modification followed. The 2006 Modification Because of the Corps' denial of its application, Collier was required to remove the Flow-Way and redesign the project's SWMS. The most substantial change in the project was the removal of the Flow-Way and associated control structures and its replacement with a series of interconnected lakes running from north to south through the property allowing for the pass-through of surface waters from the area north of the development site into the Canal. The modification does not alter the boundaries and location of the development. However, the revised SWMS includes: five controlled basins with a total area of 718.43 acres, each of which provides treatment of stormwater prior to discharging into the pass-through system; 45.16 acres of interconnected lakes serving as a pass-through for surface waters from the north; 2.12 acres of perimeter berm backslope/ buffers/spreader swales; and 7.27 acres along the Canal for the existing 100-foot wide canal easement and proposed canal contouring. These changes also required elimination of the 39.5 acres of remnant wetlands inside the development that had previously been assessed as secondarily impacted. Also, there were 0.68 acres of additional impacts resulting from slight changes in the internal site design due to the SWMS. To partially offset these impacts, the internal wetland preserves were enlarged by 13.32 acres. The remaining impacts were mitigated with mitigation credits from the Panther Island Mitigation Bank (PIMB). (The PIMB holds a mitigation bank permit issued by the District for a wetland restoration project in Southwest Florida.) The main preserve was left unchanged, except that 36.5 acres previously dedicated to construction of the Flow-Way will be added to the main preserve and similarly enhanced and preserved. In summary, as modified under the 2006 Permit, the total onsite mitigation consists of the preservation and enhancement of 830.89 acres of wetlands, preservation of 109.58 acres of uplands, and the purchase of a total of 5.68 credits from the PIMB. At hearing, Collier also agreed to purchase from the PIMB an additional 5.68 credits within the Basin for a total of 11.36 credits. The ERP Permitting Criteria To obtain an ERP, an applicant must satisfy the conditions in Florida Administrative Code Rules 40E-4.301 and 40E-4.302. The first rule focuses primarily on water quantity, environmental impacts, and water quality, while the second rule generally requires that a public interest balancing test be made, that cumulative impacts, if any, be considered, and that the District consider past violations, if any, by the applicant of District or Department of Environmental Protection (DEP) rules. (The parties have cited no prior violations by the applicant that should be considered.) Besides these two rules, a number of BOR provisions which implement the rule criteria must also be taken into account. If an applicant proposes to modify an existing ERP, as it does here, Florida Administrative Code Rule 40E-4.331(2)(a) comes into play and requires that the District review the application to modify the ERP "using the same criteria as new applications for those portions of the project proposed for, or affected by, the modification." Under this rule, those portions of the project altered or affected by the modification are reviewed under the current ERP criteria, but otherwise the 2002 Permit is not the subject of review in this case. Therefore, the District's review includes only that portion of the existing permit that is proposed to be modified or affected by the modification. In this case, the 2006 design is very similar to the 2002 design, and the project's footprint, control elevations, roadway network, southern outfall, and main preserve are unchanged. However, as pointed out below, since most of the engineering-related components of the SWMS were affected by the Flow-Way's removal, the District reassessed the hydrologic components of the internal water management system and the pass- through lake system for levels of flood protection and water quality treatment. Because most of the engineering-related components of the SWMS for the project were modified as a result of the removal of the Flow-Way, the District staff reassessed the project's hydrologic calculations associated with levels of flood protection and reassessed the project's water quality treatment volumes applying the currently existing ERP criteria. As to wetland impacts and mitigation, review of the wetland impacts for the 2006 Permit was limited to an analysis of additional wetlands impacts associated with the modification. This was primarily the elimination of the previously permitted, secondarily impacted wetlands. Thus, only the additional wetlands impacts due to the revised SWMS are considered under the currently existing ERP criteria. The 2006 Permit made only slight changes to the project's wetland impacts and mitigation components authorized under the 2002 Permit. The project's footprint was not changed and the main mitigation area (the Northern Preserve) was unaffected by the changes except that 36.50 acres were actually added to that preserve as a result of the removal of the Flow- Way. Collier did not receive any credit in its mitigation analysis for the additional acreage that will become part of the preserve due to the removal of the Flow-Way. Surface Water Management Criteria As noted above, the ERP criteria in Florida Administrative Code Rule 40E-4.301 focus primarily on three areas of concern: water quantity, environmental impacts, and water quality. Related BOR provisions must also be considered. These areas of concern are discussed below. Water Quantity Florida Administrative Code Rule 40E-4.301(1)(a) requires that an applicant provide reasonable assurance that the construction of a SWMS "[w]ill not cause adverse water quantity impacts to receiving waters and adjacent lands." BOR Section 6.2 implements that provision and requires that a project be designed so that it is consistent with the downstream carrying capacity of the receiving waters. In other words, it must not exceed the capacity of downstream receiving waters, which in this case is the Canal. In making this determination, Section 6.3 of the BOR requires that the 25-year, 3-day design storm event be used. Collier complied with this requirement through an extensive hydrologic study conducted by its expert, Richard S. Tomasello, a former District employee. Applying a hydrologic model simulation known as S2DMM, the witness determined the appropriate amount of upstream sheet flow that would need to be routed through the project to avoid adverse water quantity and flooding impacts and calculated the correct dimensions of the intake weir to admit that flow into the project's pass-through system. The S2DMM model is a combination of other accepted models including the Sheet 2d, Massmod, and MBR models, which were developed by Mr. Tomasello, and they have been evaluated and used by the District on numerous occasions. In addition, the S2DMM model has been used for other flood studies in Collier and Lee Counties, and it will be used on a restoration project in Martin County. Based upon Mr. Tomasello's analysis, Collier incorporated a 100-foot-long intake weir with a crest elevation of 14.95 NGVD (National Geodetic Vertical Datum) along the northern boundary of the project to maintain existing upstream water elevations. Collier also complied with BOR Section 6.3, which requires the use of a 25-year, 3-day storm event to be used when computing the discharge rate for the project. The modified intake weir on the northern boundary includes two 3.5-foot wide rectangular notches set at an elevation of 14.00 NGVD, which will provide a "base flow" of up to 20 cfs into the pass-through lakes to mimic the current flow through the property. The determination of this base flow was made through an analysis of the existing culverts at the southern end of the property. While not required by the ERP criteria, Collier also performed a long-term analysis (using a four-year period of record) of the SWMS's effect upon water levels. This analysis demonstrated that the modified system would leave water levels in the wetland areas upstream of the project unchanged during normal rainfall and low-flow periods. This analysis provides additional assurances that the modifications to the SWMS will not affect the Northern Preserve. While Petitioners questioned the accuracy and reliability of the hydrologic study, and its specific application to this project, the criticisms are considered to be vague and unsubstantiated. As noted above, the model has been previously accepted for use in South Florida, and Petitioners' expert conceded he did not have enough information to determine the model's accuracy. The more persuasive evidence established that the hydrologic study submitted by Collier included the relevant available data and was prepared by competent professionals knowledgeable in the field. The claim of Petitioners' experts that they lacked sufficient information to form an opinion on the accuracy of the modeling is not a sufficient basis to overcome the evidence submitted by Collier to meet this criterion. The project's discharge rate in 2006 will not exceed what was permitted in the 2002 Permit. During the 25-year, 3-day storm event, the existing discharge from the project site and the natural area west of the project site into the Canal is 553 cfs. Based on modeling of the modified SWMS, the total discharge from the pass-through system will be 529 cfs, or 24 cfs less than the project's existing pre-development discharge. The discharges resulting from the project as modified in 2006 will not exceed the capacity of the Canal as required by Section 6.3 of the BOR. Accordingly, Collier has provided reasonable assurance that the discharge rate allowed for its project would not be exceeded, as required in Section 6.2 of the BOR. Section 6.8 of the BOR requires that a project allow the passage of drainage from offsite areas to downstream areas, which is necessary to demonstrate that off-site receiving water bodies are not being adversely affected. Collier complied with this provision by conducting the hydrologic analysis using the 25-year, 3-day design storm event, which demonstrated that the discharge rate would be directed to the southern discharge point allowing for the passage of drainage from offsite areas to the downstream areas. The evidence also shows that the current predominant sheetflow from areas outside the project passes through a narrowly constricted area west of the project and discharges into the Canal over an existing concrete weir. See Finding of Fact 9, supra. Only a small portion of the upstream waters currently discharge through the Mirasol site. Petitioners' allegation that the construction of the project will further constrict the sheetflow area is rejected, as the constriction of sheetflow will continue to exist whether the project is built or not. The evidence also shows that the project will not further constrict the flow because it will allow for the pass-through of water from outside the project area. Under the 2002 Permit, the Flow-Way was designed to aid in the diversion of upstream flows around the project. Under the 2006 modifications, the pass-through lake system will convey up to forty percent of the upstream flow through the development which complies with the provisions of Section 6.8 of the BOR. As indicated above, during periods of lower water levels, the notches in the weir along the northern boundary will allow for the flow to pass onto the project site consistent with existing conditions. During major storm events, water will pass over the weir into the pass-through lake system to be conveyed to the Canal. Therefore, Collier has provided reasonable assurance that the criteria in Section 6.8 have been met. Section 6.10 of the BOR requires that the project be designed to conserve water and site environmental values and not lower the water table or groundwater or over-drain wetlands. Section 6.11 of the BOR provides that the control and detention elevations for the project must be established at elevations to accomplish the objectives of Section 6.10. The latter section is adhered to when the control elevations proposed for a project are established consistent with the onsite wetland conditions. In this case, the control elevations for the wetlands and surface water management lakes are essentially the same as the design in the 2002 Permit. Collier has set the control elevations above the average wet season water table (WSWT) for the area, thereby ensuring that the SWMS will not over-drain and will conserve fresh water. Section 6.11 of the BOR addresses Detention and Control Elevations which are intended to assist in complying with the provisions of Section 6.10. The SWMS design control elevation maintains the detention component and the control (wetland protection) elevations in the previously approved SWMS. The control elevations were set by the design engineers in consultation with Collier's wetland ecologist taking into account the ground elevations and biological indicators. The control elevation for the pass-through system and internal drainage basins work in conjunction with the control elevation along the northern boundary of the project and the control elevation for the discharge point along the southern boundary to ensure that the project does not overdrain the wetlands and to preserve the project site's environmental values. By setting the control elevation above the WSWT, the design ensures that the wetlands will not be drawn down below the average WSWT and the SWMS will not over-drain them. Section 6.10 also requires that a project not lower water tables so that the existing rights of others would be adversely affected. Again, based on the control elevations, the water table is not expected to be lowered so there should be no effect on the existing rights of others. Collier must further demonstrate that the site's groundwater recharge characteristics will be preserved through the design of the SWMS. Collier complied with this requirement by setting the control elevations above the average WSWT, allowing standing water in the wetland preserves to recharge the groundwater. The ability of the SWMS to accept flows from the Northern Preserve conserves freshwater by preventing that water from being discharged downstream. The SWMS leaves water elevations in the Northern Preserve unchanged. Consequently, water will remain in the wetlands for the same duration and elevations as in the existing conditions, thereby preserving groundwater recharge characteristics. Section 6.12 of the BOR prohibits lake designs that create an adverse gradient between the control elevations of the lakes and the adjacent wetlands. To satisfy this requirement, Collier set all control elevations at 13.4 - 13.5 NGVD while controlling the internal wetland preserves at a slightly higher elevation. Consequently, there is no adverse gradient and no potential for an adverse effect upon the internal preserves from adjacent lakes. Petitioners argued that the pass-through system would quickly lower water levels in the internal wetland preserves. However, the internal wetlands are still protected from drawdown because there are control structures set at or above the wet season elevation between the pass-through lakes and internal wetlands. They also argued that the internal wetlands would be overdrained during the dry season by the deep lakes. However, no witness presented any real analysis to back up this contention. Indeed, the pass-through lakes are only twelve feet deep, and the wetlands are separated from all the lakes by protective berms to avoid any drawdown. In summary, Collier has provided reasonable assurances that the proposed modification in the 2006 Permit will not cause adverse water quantity impacts to receiving waters or adjacent lands and will not exceed the capacity of the downstream receiving waters (the Canal). Flooding Florida Administrative Code Rule 40E-4.301(1)(b) requires Collier to demonstrate that the project "[w]ill not cause adverse flooding to on-site or off-site property." BOR Section 6.4 sets forth criteria and standards for implementing this requirement and provides that building floors be designed to be protected from a 100-year, 3-day storm event. BOR Section 6.5 provides criteria and standards for flood protection for the project's roads and parking lots. Collier complied with these provisions by providing construction plans demonstrating that the building floors and roads will be built higher than the 100-year, 3-day storm event. BOR Section 6.6 provides that a project may not result in any net encroachment into the 100-year floodplain. Collier was also required to comply with the historic basin provision in Section 6.7 of the BOR, which requires the project to replace or otherwise mitigate the loss of historic basin storage provided by the site. The level of encroachment into the 100-year flood plain and loss of historic basin storage attributed to the project are essentially unchanged from the 2002 design. The only difference between the 2002 Permit and the 2006 Permit is how the conveyance of flood water is provided. In 2002, the Flow-Way served this function, while the pass-through system provides it in the 2006 Permit. Collier's flood simulations demonstrated that the project will not alter flood stages during the 25-year and 100- year design storms, while the testimony of witnesses Tomasello and Waterhouse established that the project will not have adverse flooding impacts on adjacent properties, either alone or in conjunction with neighboring developments. Storage and Conveyance Florida Administrative Code Rule 40E-4.301(1)(c) requires that an applicant demonstrate that the proposed development "[w]ill not cause adverse impacts to existing surface water storage and conveyance capabilities." This criterion is closely related to paragraph (1)(b) of the same rule, which prohibits adverse flooding to onsite or offsite property. Section 6.6 of the BOR implements this provision and specifies the parameters for applying this criterion and prohibits a net encroachment between the WSWT and the 100-year event which will adversely affect the existing rights of others. Collier addressed this criterion through the hydrologic analysis submitted. As previously found, that model is the appropriate model to determine flood stages and to calculate the floodplain. Engineering Design Principles Florida Administrative Code Rule 40E-4.301(1)(i) requires an applicant to provide reasonable assurances that the SWMS "[w]ill be capable, based on generally accepted engineering and scientific principles, of being performed and of functioning as proposed." Section 7.0 of the BOR contains the specific standards and criteria to implement this rule. The evidence demonstrates that the SWMS is based on generally accepted engineering and scientific principles and is capable of performing and functioning as proposed. Section 8.0 of the BOR includes various assumptions and information regarding the design of the SWMS. By incorporating these assumptions into the design, Collier complied with Section 8.0. Water Quality Impacts Florida Administrative Code Rule 40E-4.301(1)(e) requires that the proposed modification "[w]ill not adversely affect the quality of the receiving waters such that the water quality standards set forth in Chapters 62-4, 62-302, 62-520, 62-522 and 62-550, F.A.C., including any antidegradation provisions of paragraphs 62-4.242(1)(a) and (b), subsections 62- 4.242(2) and (3), and Rule 62-302.300, F.A.C., and any special standards for Outstanding Florida Waters and Outstanding National Resource Waters set forth in subsections 62-4.242(2) and (3), F.A.C., will be violated." Stated more plainly, the proposed modifications must not adversely affect the quality of the Canal's waters such that State water quality standards will be violated. Section 5.2 of the BOR describes the District's standard water quality criteria. This provision, which requires a minimum of one-inch detention of stormwater, is referred to as a "presumptive criteria" because it is presumed that if an applicant provides the required one inch of detention, it meets Class III water quality standards, thereby satisfying the rule. As it did under the 2002 Permit, Collier satisfies the presumptive criteria with the 2006 design by providing the one- inch wet detention in its lake system. In fact, the system is designed to provide one and a half inches of treatment in the lake system thereby providing additional treatment. The receiving body of water for the project is the Canal. When the 2002 Permit was issued, the Canal was classified as a Class III water body. It is now classified by DEP as impaired for iron and dissolved oxygen. Because of this new classification, Collier must now comply with Section 4.2.4.5 of the BOR, which reads as follows: If the site of the proposed activity currently does not meet water quality standards, the applicant must demonstrate compliance with the water quality standards by meeting the provisions in 4.2.4.1, 4.2.4.2, and 4.2.4.3, as applicable, and for the parameters which do not meet water quality standards, the applicant must demonstrate that the proposed activity will not contribute to the existing violation. If the proposed activity will contribute to the existing violation, mitigation may be proposed as described in subsection 4.3.1.4. Collier demonstrated that neither short-term (during construction) nor long-term (during operation) water quality impacts will occur. It complied with the short-term requirements by submitting a Construction Pollution Prevention Plan detailing how water quality will be protected during the construction process. As to long-term impacts, the Terrie Bates Water Quality Memorandum (Bates Memo) prepared by District staff on June 11, 2004, provides guidance on the implementation of Section 4.2.4.5 for projects which discharge into an impaired water body. The document sets forth a number of design and operational criteria for the types of additional measures that can be incorporated into a project design to provide the necessary reasonable assurance. The Bates Memo suggests that an additional fifty percent of treatment be incorporated into a SWMS. Collier complied with this suggestion by designing the treatment lakes to provide an additional one-half inch of treatment for the additional fifty percent treatment. In addition to the one and one-half inch treatment, Collier is implementing six of the seven items the Bates Memo lists as potential options to consider. The long-term water quality requirement is addressed by Collier, in part, through an Urban Stormwater Management Plan, which details various source controls or best management practices to be implemented once the project is built and operating. Best management practices assist in ensuring that pollutants will not enter into the lake system. Collier is also implementing a stormwater pollution prevention plan and will utilize the lake system for additional treatment downstream. Collier has further agreed to planting the littoral zones as part of its design of the treatment lakes to provide additional pollutant removal. The design calls for an amount of littoral zones equal to twenty percent of the surface area of the treatment lakes. Collier has agreed to make a Water Quality Monitoring Plan a permit condition, even though such a condition was not included in the staff report. See Collier Exhibit 25. The Bates Memo includes as an option for meeting the long-term requirement a site-specific water quality evaluation of pre vs. post-development pollutant loadings. Collier has presented several such analyses, all of which indicate the post- development pollutant discharges from the site will be less than the pre-development. Mr. Barber prepared a pre vs. post- analysis using a 2003 methodology developed by Dr. Harper. The 2003 version of the Harper methodology is currently accepted by the Corps. (Although Petitioners' witness, a former Corps employee, suggested that the Corps' acceptance of the study was a "political" rather than a scientific decision, there is insufficient evidence to support this contention.) Besides his first analysis, at the direction of the District staff, Mr. Barber prepared a second analysis using the 2003 methodology with certain conservative assumptions that limited the pollutant residents time to fifty days and utilized lower starting concentrations for phosphorous and nitrogen than were recorded in the nearby monitoring stations. Based upon those reports, the District's staff concluded that Collier had provided reasonable assurances that the project met the criteria in BOR Sections 5.2 and 4.2.4.5. At the hearing, Mr. Barber presented a third analysis utilizing an updated methodology developed by Dr. Harper in February 2006. The 2006 methodology was developed after Dr. Harper conducted a study of water management district criteria throughout the state for DEP. All three of the analyses prepared by Mr. Barber concluded that the project would discharge less nitrogen and phosphorous into the receiving body in the post-development condition than is currently being discharged in the pre-development condition. In addition to the three water quality submittals from Mr. Barber, Collier provided an additional water quality analysis specific to the project prepared by Dr. Harper. See Collier Exhibit 26, which is commonly referred to as the Harper Report. The analysis evaluated the project's pre vs. post- development water quality loads and also concluded the project would not contribute to the impairment of the Canal. In preparing his analysis, Dr. Harper relied solely on the lakes for estimating removal of pollutants without accounting for any of the additional treatment expected to occur from the source control best management practices contained in the Urban Stormwater Management Plan, which means his report errs on the conservative side. The Harper Report concluded that iron discharges from the SWMS would be extremely low and substantially less than the Class III standard of 1 mg/L. Petitioners presented no specific evidence to counter these conclusions. Petitioners questioned the Harper Report's use of wetlands as part of the loading calculations and attacked his underlying methodology. However, the evidence is clear that wetlands contribute to the water quality constituents in the pre-development condition. This finding is based on data from monitoring stations located in the middle of Corkscrew Swamp, a statewide study on stormwater treatment and wetlands, and the United States Environmental Protection Agency's (EPA) assignment of nutrient loading rates to wetlands in its regional pollutant loading model. Ignoring the actual water quality in pre-development conditions would not be a true pre vs. post-development analysis. Finally, Petitioners' contention that the Harper methodology should not be considered as admissible evidence because it constitutes "novel" (and therefore unreliable) scientific evidence under the rationale of Frye v. United States, 293 F. 1013 (D.C. Cir. 1923), has been rejected. To begin with, the Frye test has not been accepted in Florida administrative proceedings. Moreover, the methodology is the basis for a new statewide rulemaking effort, has been accepted by the EPA, the Corps, and by the Division of Administrative Hearings in at least two proceedings, and has been subjected to two peer reviews. Petitioners also alleged that Collier failed to show that it complied with Florida Administrative Code Rule 62- 40.432(2)(a)1., a rule administered by DEP which requires that a new SWMS "[a]chieve at least 80 percent reduction of the average annual load of pollutants that would cause or contribute to violations of state water quality standards." However, this is a broad overstatement of DEP's rule. Also, there is no eighty percent removal efficiency requirement adopted or incorporated into any District rule or BOR criteria. See, e.g., Conservancy of Southwest Florida, Inc. v. G.L. Homes of Naples Associates II, LTD et al., DOAH Case No. 06-4922 (DOAH May 15, 2007, SFWMD July 11, 2007). Instead, the District's "presumptive criteria" is that one inch of volumetric treatment required in Section 5.2 of the BOR meets the Class III standards. If, as in this case, additional assurances are required, those assurances are met through implementation of the BOR Section 4.2.4.5. Finally, Florida Administrative Code Rule 62-40.110(2) provides that Rule Chapter 62-40 is "intended to provide water resource implementation goals, objectives, and guidance for the development and review of programs, rules, and plans relating to water resources." Also, Florida Administrative Code Rule 62- 40.110(4) states that "[t]his chapter, in and of itself, shall not constitute standards or criteria for decisions on individual permits. This chapter also does not constitute legislative authority to the Districts for the adoption of rules if such rules are not otherwise authorized by statute." Even if an eighty percent reduction standard applied, Collier has demonstrated that the project very likely will remove eighty percent or more of pollutants when additional low-impact development techniques, pollutant source reduction practices, and additional uncredited wet and dry detention capacity are considered. Based upon the evidence presented, Section 4.2.8 of the BOR regarding cumulative impacts for water quality is not applicable in this case. Collier's submittals provide reasonable assurances that the project will not be contributing to the water quality impairment of the Canal or contribute to any other water quality violation. Indeed, the information submitted indicates there will be an incremental improvement in the post-development condition as compared to existing. Since no contribution or impacts to water quality are expected, a cumulative impact analysis is not necessary to assess the extent of the impacts. The combination of all these water quality measures, when taken together, demonstrates that the 2006 Permit will not adversely affect the quality of receiving waters such that state water quality standards will be violated. Therefore, reasonable assurance has been given that Florida Administrative Code Rule 40E-4.301(1)(e) will be satisfied. Wetland Impacts Florida Administrative Code Rule 40E-4.301(1)(d) requires Collier to provide reasonable assurance that the modification of the SWMS "[w]ill not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters." In determining whether this criterion has been satisfied, it is also necessary to determine whether any 2002 permitted impacts should be subject to a second review in this case. Mitigation is a method by which an applicant can propose to impact certain wetlands on the project site in exchange for providing compensation in the form of preserving, enhancing, restoring, or creating wetlands or uplands to offset those impacts. As noted earlier, there has been no change to the wetland impacts or mitigation proposal as it relates to the Northern Preserve. See Findings of Fact 27 and 28, supra. As a result of the modified SWMS, there has been some additional impact to wetlands within the development area of the project. An additional 40.18 acres will be impacted under the 2006 Permit mostly due to the modified SWMS system. However, 39.5 acres of those wetlands were already considered secondarily impacted under the 2002 Permit. In addition, the preserve areas were expanded by 13.32 acres in the 2006 design. Thus, a portion of the impacts to those wetlands was already factored into the mitigation plan that was developed and approved for the 2002 Permit. As a result, there are 26 acres for which mitigation is necessary under the 2006 Permit. Section 4.3 of the BOR specifies criteria for mitigation proposed as part of an ERP application. Collier has proposed an acceptable mitigation plan for the new wetland impacts that will result from the project due to the proposed modifications incorporated in the 2006 Permit. Except for the mitigation for the additional wetland impacts, the mitigation plan for the 2006 Permit remains essentially unchanged from the 2002 Permit, including the Grading and Planting Plan, Monitoring Plan, and Mitigation, Monitoring, and Maintenance Plan. The onsite mitigation proposal includes preservation and restoration of wetlands through the removal of melaleuca and other exotic plants and replanting in areas of dense exotic species coverage. Significantly, Collier has not proposed any modifications that would change the effectiveness of the Northern Preserve in providing mitigation for the wetland impacts proposed and approved in the 2002 Permit. While Petitioners claim that the wetlands in the Northern Preserve may be subject to some changes in the level and seasonality of inundation as a result of the SWMS modifications, the evidence does not support those assertions. The revised SWMS will continue to allow water to flow through the Northern Preserve in a manner consistent with existing conditions while providing some flood control protection for extreme rainfall events. Petitioners also suggest that additional analysis regarding the timing and levels of inundation in the wetland preserves is necessary to fully determine the impacts of the modified SWMS on the wetlands. However, the more persuasive testimony indicates that the timing and levels within the wetlands will not be affected by the revised SWMS. The control elevations within the development area have not changed from the 2002 Permit, and these protect the onsite wetlands and ensure that those wetlands will function as expected. With respect to the internal wetlands within the development area, the control elevations have not changed from the 2002 Permit and the evidence establishes that the internal wetlands will continue to function and operate as contemplated in the 2002 Permit. There has been some relocation and reconfiguration of the internal wetland preserve areas that will actually enhance the value of the mitigation by connecting those wetland areas to other preserve areas. Petitioners further suggested that the wetland mitigation within the development area would not function as permitted in the 2002 Permit due to the spill over from the lakes to the wetlands. However, when the water reaches those internal wetland preserves, it has been treated to Class III water quality standards. Therefore, the mitigation values of those wetlands preserves will not be changed or affected due to water quality. Petitioners' objections to the wetland impacts and mitigation were primarily directed at the overall impacts rather than to the 2006 modifications. However, their witness was unaware of the values provided by the additional acres that will be impacted through the 2006 Permit. Therefore, a challenge to 2002 permitted wetlands impacts and mitigation is inappropriate in this proceeding. Functions To Fish and Wildlife and Listed Species Section 4.2.2 of the BOR implements Florida Administrative Code Rule 40E-4.301(1)(d) and provides that an applicant must provide reasonable assurances that a project will not cause adverse impact to the abundance and diversity of fish, wildlife, and listed species or their habitat. With respect to the 586.66 acres of wetland impacts permitted in the 2002 Permit, the 2006 Permit does not modify or affect the values that the wetlands provide to either the abundance or diversity of fish and wildlife. Review of the wetlands criteria as to those acres was finally determined in the 2002 Permit and should not be reopened. By relocating thirteen of the previously impacted acres so they are most closely connected to other wetlands, their value to fish and wildlife will increase. As explained by the District's witness Bain, if Collier had moved the preserve area and changed its functional value, the District would have been required to reevaluate the mitigation that had been accepted for the wetland impacts in the 2002 permit. In this case, however, because the Northern Preserve area did not change, the District's review is limited to the newly impacted wetlands internal to the development for which mitigation was not provided in the 2002 Permit. Section 4.2.2.3 of the BOR addresses the functional assessment of the values provided by the project's wetlands. The only wetland values assessed in the 2006 Permit were the additional wetland impacts that were not mitigated in the 2002 Permit. The evidence establishes that the current value of the wetlands is low due to the heavy melaleuca infestation, which is greater than fifty percent coverage in most locations and seventy-five percent or more in much of the area. Melaleuca has the effect of draining short hydroperiod wetlands. While Petitioners may disagree with how the wetlands were previously evaluated, nothing in the 2006 modification allows or requires a reassessment of their value. Section 4.2.2.4 of the BOR requires that a regulated activity not adversely impact the hydroperiod (the depth, duration, or frequency of inundation) of wetlands or other surface waters. Subsection (a) of this standard applies if the project is expected to reduce the hydroperiod in any of the project's wetlands. Conversely, subsection (b) applies if the project is expected to increase the hydroperiod through changing the rate or method of discharge of water to wetlands or other surface waters. Subsection (c) requires monitoring of the wetlands to determine the effects of the hydrological changes. Again, there is no basis for the District to reopen and reevaluate the wetlands for which mitigation has already been permitted. No evidence was presented to indicate that there would be any obstacles or problems to accomplishing the mitigation that was proposed and accepted in 2002. In any event, the engineering and biological testimony demonstrated that no change (neither a reduction nor an increase) in the hydrology on the preserved wetlands or the Northern Preserve will occur from what was permitted in the 2002 Permit. By analyzing the various biological indicators onsite and setting the control elevations within the SWMS and the wetlands (both the Northern Preserve and onsite preserve wetlands) above the WSWT, the project ensures that the appropriate hydrology will be maintained. Though the fish and wildlife are not expected to be adversely affected by the 2006 Permit, Collier will be conducting monitoring of plants and animals on the site as an extra measure of assurance as contemplated under BOR Section 4.2.3.4(c). Focusing on just the changes from 2002 to 2006, Petitioners' two experts conceded that the hydrology in the Northern Preserve and its value to wildlife and listed species (including the wood stork) would be benefited in the 2006 Permit over that contemplated in the 2002 Permit due to the removal of the Flow-Way. Secondary Impacts to Water Resources Florida Administrative Code Rule 40E-4.301(1)(f) requires a demonstration that the proposed activities "[w]ill not cause adverse secondary impacts to the water resources." A similar demonstration is required by Sections 4.1.1(f) and 4.2.7 of the BOR. In this case, the secondary impacts considered by the District were potential impacts due to the relocation and expansion of the buffer preserve areas to the perimeter of the project site. In conducting a secondary impact analysis, BOR Section 4.2.7 requires that the District consider only those future projects or activities which would not occur "but for" the proposed system. Here, the evidence demonstrated that no wetlands or other surface waters will be secondarily impacted by the modifications to the SWMS as part of the 2006 Permit. The undersigned has rejected Petitioners' contention that a proposed extension of County Road 951 through the development site should be considered a secondary impact in evaluating this project. This extension has been proposed for at least fifteen years and its precise configuration is unclear. It is not required to be built as a result of the project and there are no firm plans or contracts in place to construct the road. Although the road is listed on the County's transportation plan, it remains speculative as to if and when it will be built. Additionally, there is no evidence the County has any ownership interest in property for a road in the area identified by Petitioners. Witness Bain testified that the District examined the Collier County Public Records and an easement had not been granted to the County to build the road. i. Elimination and Reduction Florida Administrative Code Rule 40E-4.301((3) provides in part that "the provisions for elimination or reduction of impacts contained in the [BOR] shall determine whether the reasonable assurances required by subsection 40E- 4.301(1) and Rule 40E-4.302, F.A.C., have been provided." Section 4.2.1.1 of the BOR implements that provision and provides that elimination and reduction of impacts is not required when: The ecological value of the function provided by the area of wetland or other surface water to be adversely affected is low based on site specific analysis using the factors in subsection 4.2.2.3 and the proposed mitigation will provide greater long term ecological value than the area of wetland or other surface water to be adversely affected; . . . In accordance with that section, Collier was not required to implement practicable design modifications to reduce or eliminate impacts. The District did a site-specific analysis of the quality of the 39.5 acres of adversely affected wetlands, taking into consideration the condition of the wetlands, hydrologic connection, uniqueness, location, and fish and wildlife utilization. The unrebutted testimony is that the quality of the 39.5 acres of wetlands to be impacted by the 2006 Permit is low and these wetlands were already previously authorized to be secondarily impacted. The low quality wetlands are melaleuca dominated making them not unique. The mitigation will provide greater long-term ecological value than the impacted wetlands. As noted on page 10 of the Staff Report, there will be a larger, contiguous mitigation area to offset direct impacts to previously preserved, but secondarily impacted wetlands and the preservation/enhancement of the external preserve area. The 2006 Permit provides that 5.68 credits are required to be purchased in the PIMB. Collier has advised the District that 27.68 credits are being purchased pursuant to its Corps permit. Thus, Collier will be purchasing more credits than required by the District. Witness Bain took this additional mitigation into account in determining whether the proposed mitigation will provide greater long term ecological value than the area impacted. While the Corps permit is an entirely separate permit action, Collier has agreed to include an additional 5.68 credits within the Basin beyond what is required in the Staff Report as a condition to this 2006 Permit. Therefore, the mitigation is clearly of greater long-term ecological value than the area impacted. Additional Requirements Florida Administrative Code Rule 40E-4.302 imposes additional requirements on an ERP applicant, including a cumulative impact assessment, if appropriate, and satisfaction of a public interest test. Cumulative Impacts Florida Administrative Code Rule 40E-4.302(1)(b) requires that an applicant demonstrate the project "[w]ill not cause unacceptable cumulative impacts upon wetlands and other surface waters as set forth in subsections 4.2.8 through 4.2.8.2 of the [BOR]." Cumulative impacts are the summation of unmitigated wetland impacts within a drainage basin, and a cumulative impact analysis is geographically based upon the drainage basins described in Figure 4.2.8-1 of the BOR. See Florida Wildlife Federation et al. v. South Florida Water Management District et al., 2006 Fla. ENV LEXIS 49 at *49, DOAH Case Nos. 04-3064 and 04-3084 (DOAH Dec. 3, 2006, SFWMD Dec. 8, 2006). Also, Section 373.414(8)(a), Florida Statutes, requires the District to consider the cumulative impacts upon surface water and wetlands within the same drainage basin. Thus, the cumulative impact analysis applies only when mitigation is proposed outside of the drainage basin within which the impacts are to occur. Broward County v. Weiss et al., 2002 Fla. ENV LEXIS 298 at *29, DOAH Case No. 01-3373 (DOAH Aug. 27, 2002, SFWMD Nov. 14, 2002). In this case, all of the proposed mitigation associated with the 2006 Permit modifications is located within the West Collier Basin. The evidence shows that the mitigation will offset the impacts to wetlands proposed in the 2006 Permit. Therefore, since the mitigation will be performed in the same Basin as the impacts and will offset the adverse impacts, the District must "consider the regulated activity to meet the cumulative impact requirements" of Section 373.414(8)(a), Florida Statutes. A new cumulative impacts analysis based on removal of the Flow-Way is not necessary because the modification does not change the cumulative impacts analysis conducted in the 2002 Permit. Since the Flow-Way was not considered a wetland impact or contributing to the mitigation in the 2002 Permit, its removal does not affect the adequacy of the previously conducted cumulative impacts analysis or the mitigation. Accordingly, there is no need for a new cumulative impact analysis with regards to the Northern Preserve. Finally, contrary to Petitioners' assertion, there is no rule or BOR provision which requires Collier to mitigate for the alleged prior impacts of other projects. Public Interest Test In addition to complying with the above criteria, because the project is located in, on, or over wetlands or other surface waters, Collier must also address the criteria contained in the Public Interest Test in Florida Administrative Code Rule 40E-4.302(1) and Section 4.2.3 of the BOR by demonstrating that the project is not contrary to the public interest. See also § 373.414(1)(a), Fla. Stat. Since the project does not discharge into an OFW or significantly degrade an OFW, the higher standard of "clearly in the public interest" does not apply. In determining compliance with the test, Florida Administrative Code Rule 40E-4.302(1)(a) requires that the District do so by "balancing the [seven] criteria [in the rule]." Findings with respect to each of the seven criteria are set out below. (Except for pointing out that the District does not have an adopted rule which provides more specific detail on how to perform the balancing test than is now found in paragraph (1)(a), and a contention that witness Bain's testimony was insufficient to explain how the staff balanced those factors, Petitioners did not present any evidence at hearing or argument in their Proposed Recommended Order in support of their contention that the above rule, BOR section, or the associated statute have been applied by the District in an unconstitutional manner.) Whether the regulated activity will adversely affect the public health, safety, or welfare or the property of others (40E-4.302(1)(a)1.) Collier provided reasonable assurances that the project will not cause any onsite or offsite flooding nor cause any adverse impacts to adjacent lands because the SWMS is designed in accordance with District criteria. Also, the post- development peak rate of discharge does not exceed the allowable discharge rate. Further, the project will not cause any environmental hazards affecting public health, safety, or welfare. The project is considered neutral as to this factor. Whether the regulated activity will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats (40E-4.302(1)(a)2.) For the direct wetland impacts under the 2006 Permit, Collier proposes mitigation which has not changed from the 2002 Permit. The mitigation proposed was previously determined to offset potential impacts to fish and wildlife and particularly wood stork habitats. The evidence indicates that the mitigation plan for the Northern Preserve will improve wood stork habitat from its current melaleuca infested condition. For the additional 40.18 acres of wetland impacts authorized in 2006, the mitigation is of greater long-term value. Thus, the project should be considered positive as to this factor. Whether the regulated activity will adversely affect navigation or the flow of water or cause harmful erosion or shoaling (40E-4.302(1)(a)3.) The parties have stipulated that the project will not adversely affect navigation. In addition, no evidence was introduced to suggest that the project's construction would result in harmful erosion or shoaling. Whether the regulated activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity (40E-4.302(1)(a)4.) The project does not provide any fishing, recreational values, or marine productivity. Therefore, the project is neutral as to this factor. Whether the regulated activity will be of a temporary or permanent nature (40E-4.302(1)(a)5.) It is undisputed that the project is permanent in nature. Even though the project is permanent, it is considered neutral as to this factor because mitigation will offset the permanent wetland impacts. Whether the regulated activity will adversely affect or will enhance significant historical and archaeological resources under the provisions of Section 267.061, F.S. (40E- 4.302(1)(a)6.) The parties have stipulated that no significant archeological or historical resources have been identified on this site. Therefore, the project is considered neutral as to this factor. The current condition and relative value of functions being performed by areas affected by the proposed regulated activity (40E-4.302(1)(a)7.) The current condition and relative value of functions being performed by the areas affected by the project is low due to the melaleuca infestation. Project mitigation will restore 940 acres of poor quality wetlands and uplands, greatly enhancing their function and value. Therefore, the project should be considered positive as to this factor because the implementation of the mitigation offsets the wetland impacts and improves the current value. Summary of Public Interest Factors Overall, the project is no worse than neutral measured against any one of the criteria individually. Therefore, the project is not contrary to the public interest.

ALEXANDER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 24th day of July, 2007.
Findings Of Fact Existing Conditions Between 1952 and 1957 the United States Army Corps of Engineers (Corps) and the Florida Central and Southern Flood Control District (the forerunner of SFWMD) constructed a chain of levees, L-1, L-2, L-3 and later L-4 in eastern Hendry County, Florida. These levees which begin approximately 10 miles to the southwest of Lake Okeechobee run first east, then south and then east again for a distance of approximately 38 miles. The purpose of these levees is to shield the land5/ to the east of them from the natural sheet flow of water which comes from the west during the area's rainy season. The EAA which is protected from natural flooding consist of rich muck soils which have been successfully exploited for years by sugar cane farming. The present levees were created by excavating a "borrow" canal parallel to the southern and western sides of L-1, 2, 3 and 4. The borrow canal is no larger than was required to provide sufficient material for construction of the levees; nevertheless, the canal has a considerable water carrying capacity in the amount of 1,260 CFS 6/ at peak flow. The canal is a navigable fresh water of the state. It interconnects into other navigable canals which terminate in either Lake Okeechobee or the Miami River. The water carried by the borrow canal flows south and discharges into the Miami canal via either a pumping station designated S-8, or via the borrow canal next to L-28.7/ The water which enters the Miami canal ultimately travels to canal C-60 and then into the section of WCA-3 south of Alligator Alley (State Road 84). Flooding The rain water which once moved from west to east directly across the eastern portion of Hendry County, Florida into the EAA is now interdicted by L- 1, 2 and 3. As a result it ponds in the corner of the intersection of L-1 and L-2 (known in these proceedings as the L-1 angle). The area flooded is grass land used by Hendry County ranchers for the open grazing of beef cattle. Some of the pasture is improved, that is fertilized, but the majority of the area is unimproved range. During flood times the ranchers move their cattle to alternative pastures either to the north or to the west. The deepest flooding, when it occurs, is immediately next to the levees in the L-1 angle. The flooding has been known to reach depths as great as 10 feet and to extend westward for several miles. Because the land to the west of the L-1 angle is higher, the depth of the flooding decreases in a westerly direction. The duration of the ponding immediately in the L-1 angle has been as long as 80 days after a prolonged and heavy rainfall event. This flooding occurs despite the capacity of the borrow canal to remove 0.18 inch of flood water per day from the inundated area. When there is flooding in the L-1 angle there is also high water In the northeast corner of WCA-3A where some of the water from the borrow canal is presently discharged. During a dry season the land immediately adjacent to the present borrow canal suffers overdraining due to seepage of ground water into the canal and its resulting evaporation or conveyance south. Water Conservation Area 3A is part of a series of conservation areas established as their name implies to conserve water. Extending over portions of several South Florida counties including Palm Beach, Broward and Dade, they provide the recharge source for the Biscayne Aquifer and other aquifers which are the water supply for metropolitan South Florida. The water conservation areas are also wildlife refuges and provide natural habitats for numerous South Florida animals such as deer, alligator, and wading birds. Description of Project The Hendry County plan as described by the Corps in General Design Memorandum No. 2, 8/ envisions the construction of a flood control canal, C- 139, with two water flow control structures, S-239 and S-243. To create C-139, the Corps plans to further excavate the existing borrow canal next to L-2, L-3 and L-4 for a total distance of 37 miles. See Illustration I.* This excavation will result in the removal of 5.2 million cubic yards of earth and limestone. Some of the resulting spoil will be used to create a levee along the west side of C-139. Most of the excavation will be done by draglines on the canal banks. Upon its completion C-139 will be an immense water conveyance. At its northern end the canal will be only five feet across the bottom with a depth of 10.6 feet, but by the time the canal reaches WCA-3A it will have enlarged to a bottom width of 80 feet across and a depth of 19.5 feet. Its peak design capacity is 3,000 CFS. That is more than twice the present capacity of the existing borrow canal. Downstream from S-239 C-139 turns south to be designated C-139(S) and to gradually become increasingly shallower. This will cause a discharge pattern designed to create a sheet flow across WCA-3A. Benefits, Future Land Use It appears that when levees L-1, 2 and 3 were constructed the Corps failed to fully consider the adverse effect which would result from the impoundment of water by the new levees. According to the General Design Memorandum, Levees 1, 2, 3 and 4 were constructed in the mid 1950s to prevent flood waters originating on the then sparsely developed lands westward of the levees from contri- buting to flooding on the rich agricultural lands lying to the east of the levees. The original borrow canals were sized based on materials needed for the levee construction. The sparse economic development of the lands to the west precluded increasing the con- veyance capacity of these canals to prevent flooding on those lands. Construction of the levees and the subsequent increased de- velopment over the drainage area have aggra- vated flooding problems on the lands. Water stands on some of the land during practically the entire wet season virtually every year. As the landowners developed the land, they became increasingly vociferous about con- struction of works to alleviate the flooding for which they contend is project-induced. There is merit in their contention in that the adjacent project works adversely affected both depth and duration of flooding in the area west of Levees 1, 2 and 3. (Emphasis added) The facts presented at the instant final hearing are somewhat to the contrary, in that there was no showing of significant subsequent development west of the levees after their construction. For many decades vast family ranches have raised cattle on the mentioned lands as they continue to do today. The primary purpose of the proposed project is to now provide flood control to an approximately 261 square mile drainage basin west of the flood-causing levees.9/ With a design capacity of 3,000 CFS, C-139 can handle twice the water which drains through the present borrow canal. By way of comparison the present canal has a drainage capacity of .18 inches per day from the flooded area during a ten-year flood,10/ while C-139 has the capacity to drain .43 inches per day. This heightened discharge rate will cause land in the L-1 angle to flood less, and once flooded, to be underwater for a shorter period of time. For instance, an area which during a ten-year storm might have been submerged for 40 days prior to the construction of the project Is estimated to have an inundation period of only 10 days upon the project's completion. The significance of the reduced flooding to the landowners in the flooded area is difficult to gauge from the evidence. Because an intensification of land use would result in a lowering in the quality of the water which runs off the land and into C-139 and thence into the environmentally sensitive water conservation area,11/ the landowners supporting the project were understandably reluctant to testify that the project will allow them to use their land for more than continued cattle grazing. The testimony of Mr. Joe Hillard, a partner in Hillard Bros. of Florida, Inc., one of the larger ranches is illustrative: Q If this project, the flood control portion, were built, would your company change any of its land uses on this land that you described? A No, sir, not at all. Not with what I understand is going to be done with the project I wouldn't change anything. In response to the Hearing Officer's later inquiry, Mr. Hillard explained that the project would allow pasture land to be used for twelve months per year as opposed to the current nine months per year during a flood season. He does not anticipate grazing any more head per acre after the project. This evidence contrasted with the assumptions made by the Corps in that part of the General Design Memorandum which discusses the cost-benefit ratio of the project. The Memorandum states at p. 52: As noted previously, the existing activity within the area is predominately agricultural with major emphasis in beef cattle production. Local landowners and managers were asked to indicate the production changes they expected to make with the reduced flood hazards available under with (sic) project condi- tions. These expectations were prepared as a land use map with the basic control matrix. For the most part, these changes in land use represented more intensive types of agricultural cultivation. In some cases, existing beef pastures were expected to be replaced with sugarcane, truck crops, and citrus production. The majority of the changes were an upgrading of existing beef cattle operations. Such upgrading was affected (sic) by planting the more pro- ductive types of pasture such as clover and grass combinations, and the application of additional fertilizers and supplemental water. These expectations were assumed to exist under favorable cultivation conditions. Because of the nature of soil conditions in the project drainage basin, sandy with poor nutrient and water retention ability, it is unlikely that land use in the 261 square mile drainage basin will change significantly. As predicted by Mr. Hillard, it is likely that all the project would do is allow more grazing time on land which is now periodically flooded. Since it is not the function of this proceeding to inquire into whether the purported cost- benefit ratio of the project is accurate, no findings will be made concerning that issue. Project Permitting History The Hendry County portion of the Central and Southern Florida Flood Control project for flood control west of levees 1, 2 and 3 was authorized by the Congress of the United States in the Flood Control Act of October 27, 1965. The Army Corps of Engineers is the actual builder of the project, but SFWMD is the local sponsor and is the Corps' agent in applying for the necessary permits from DER. The Department as the permitting agency is in a curious position here. Its Bureau of Water Resources (BWR) was responsible for the State Public Works Program through which Florida requested Congress to fund the Hendry County Project. Mr. Charles Littlejohn who was head of the Bureau in 1976 had the responsibility of lobbying in Washington for funding of the project. The DER through its Bureau of Permitting is now asked to pass on the validity of a project which the BWR has so vigorously promoted. The Department's uncomfortable posture was recognized by its permitting staff. In a memorandum dated March 9, 1979 to Mr. E.D. "Sonny" Vergara, Mr. Forrest Fields at DER wrote: I told Mr. Brown, as I told you yesterday that I felt rather awkward in reviewing for permitting a project which the agency had endorsed for the public works list." Every year projects being sponsored for federal approval are reviewed by a process In the Division of State Planning called the A-95 Clearinghouse.12/ The Hendry County Project had a checkered history there. Serious objections concerning the environmental impact of the project were raised; nevertheless, DER through the BWR continued to seek and was successful in obtaining federal funding. On November 15, 1978, SFWMD filed an application with DER for the requisite permits to begin construction. During the course of DER's review of the project several issues arose between the parties. Among them were: Whether local approval pursuant to Section 253.124, Florida Statutes would be required? Would an exception from dissolved oxygen (DO) standards be necessary? Whether local water quality standards would apply if they were stricter than state standards? Local Approval As early as February 19, 1979, DER noted that plans submitted by the applicant proposed the placement of fill in waters of the state. In a letter to Mr. Lee M. Brown of SFWMD, Mr. Forrest Fields, the DER permit processor, observed: Second, on page 2/11 of your drawings, you indicated that approximately 5,800 cubic yards of fill material will be placed water- ward of ordinary mean high water. I pre- sume that this fill is associated with structures S-243 and S-239. Pursuant to Section 253.124, Florida Statutes, approval of this filling by resolution of the local government is required. To do this I will, upon receipt of the Department of Environ- mental Regulation field report, summarize and send this to the Hendry County Commission. The Commission will have to consider this report, and, by vote, adopt a resolution approving the project. I will send you a sample resolution. The requirement of local approval was reiterated numerous times. In March, 1979, Mr. Fields sent a staff report of a biological survey of the project to the Hendry County Commission for consideration in their approval of the project. During a meeting on March 21, 1979 in the DER Secretary's office representatives of SFWMD were told that local approval would be required. On April 10, 1979 the County Commissioners of Hendry County gave their approval to the project. In correspondence to Mr. Charles Lee of the Florida Audubon Society, Secretary Jacob D. Varn noted that the permit applications were still incomplete because local approval for filling associated with the two water control structures had not yet been received by DER. During a public meeting held on May 22, 1979, the County Commissioners of Broward County, after three and one-half hours of testimony, voted 6-0 against approving the project as it related to fill in Broward County. Subsequent to that vote the Corps and SFWMD asserted that local approval by Broward County was not required. In response to this assertion Mr. Charles Littlejohn, on behalf of the Secretary, requested a legal opinion from DER's General Counsel. On October 30, 1979, General Counsel's Legal Opinion 79- 72 concluded that the Department could assert Chapter 253 jurisdiction over the project and therefore "local approval" is a statutory requirement for its permitting. On March 17, 1980 Mrs. Evelyn Jackman of Jackman and Sons, Inc., one of the major ranchers in the project drainage basin, wrote to Governor Graham to urge the rapid approval of the project. Her correspondence was forwarded to DER for an appropriate response. Ms. Victoria J. Tschinkel as Assistant Secretary noted in her reply on April 3, 1980 that: Pursuant to Section 253.124(3), Florida Statutes approval must be obtained from the County Commissioners before we can complete the processing of a permitting application for fill in navigable waters. Approval has not been received from Broward County and there Is fill proposed for the Broward County portion of the project. Ms. Tschinkel did, however, assure Mrs. Jackman that: The Department of Environmental Regulation is sympathetic to the problems outlined in your letter, and for that reason the Depart- ment has made this project part of its public works package given each year to Congress. We still support this as a public works pro- ject and for that reason we are attempting to work out the permitting problems as ex- peditiously as possible. Shortly after Ms. Tschinkel's letter was sent there was another meeting in the Secretary's office to discuss the project. Mr. Lotspeich's interoffice memorandum outlines the Department's new position as it related to local approval. In addition, the issue of what constituted fill pursuant to Chapter 253, Florida Statutes, for local approval purposes was discussed. Helen Setchfield also partici- pated in this discussion. After Helen and I looked more closely at the project, it appeared that only a concrete structure (S-239) was to be placed waterward of OHW.13/ We both agreed that in past permitting practices we had not required local approval for the construction of structures waterward of OHW, but only when fill to extend existing lands or create new lands was involved. Since the application drawings did not clearly show the relation of the fill and structure relative to OHW and sheet 2 of 11 clearly indicates that fill will be placed "below MHW" Forrest must have assumed that local approval would be required if the canal was determined to be under Chapter 253, Florida Statutes jurisdic- tion. GCO-79-72 from Randie Denker indicated that the Department can assert Chapter 253, Florida Statutes jurisdiction in the canals and therefore local approval would be required. It would appear that there was really no clear understanding as to what the "fill" consisted of in the case of structure 239. Conversation with Mr. Walker [counsel for SFWMD] and Messrs. Parsons [counsel for Alico and other landowners] and Davis [SFWMD] indicated that there was no intention to place fill in the canal waterward of OHW and that the concrete structure would span the entire canal width. Since the application drawings did not clearly show the relation of the structure and fill re- lative to existing OHW, Mr. Walker said he would provide new drawings which would show this. Helen and I discussed the situation and we scheduled an appointment to talk the problem over the (sic) Terry Cole. It was agreed at the meeting that simultaneous "intent" letters would be sent on May 5, 1980 from permitting and the exception review people. May 16, 1980 DER entered into a Stipulation with SFWMD which states in its entirety: The SOUTH FLORIDA WATER MANAGEMENT DISTRICT and the DEPARTMENT OF ENVIRONMENTAL REGULA- TION for purposes of this proceeding hereby stipulate and agree that: The DEPARTMENT OF ENVIRONMENTAL REGULA- TION has jurisdiction under Chapter 253, Florida Statutes, to require permits autho- rizing construction and other activities described in the application which is the subject of this proceeding. None of the activities or construction, including the construction of the proposed Spillway S-239, as described in the appli- cation which is the subject of this pro- ceeding, constitute construction of islands or an addition to or extension of existing lands and islands so that approval of local governments as described in Section 253.124, Florida Statutes, is not required. This Stipulation is executed by counsel for each party on the date shown. On May 20, 1980 coordinated letters of intent to grant permits for the construction of the project were issued. Pursuant to the Stipulation local approval was no longer being required by DER. Alternative Site Specific Criteria After receipt of SFWMD's permit application for the construction of C- 139 and associated structures, DIR noted that it did not have adequate data on dissolved oxygen. In correspondence dated March 9, 1979, Mr. Forrest Fields said: Fourth, the dissolved oxygen data are not adequate. The available data were col- lected during daylight, only, and these data include occasional concentrations of less than 4.0 mg/l. In an effort to re- solve these deficiencies so that reasonable assurances may be provided, you, Walt Dineen, and I will discuss the South Florida Water Management District data on Thursday, March 15. The results of the March 15, 1979 meeting were memorialized by Mr. Fields in a file memorandum dated March 19, 1979. The memorandum stated in pertinent part that: On March 15, 1979, Mr. Lee Brown, Mr. Walt Dineen, and Mr. Fred Davis, from SFWMD, called to discuss the staff's request for "reasonable assurance" re. the Department's water quality standards. Mr. Davis, the applicant's chief chemist, said that, throughout the Everglades, in both canals and conservation areas, the water quality standards for both conductivity and dis- solved oxygen are frequently violated. He asserted that this is typical of the area. He believes that these data represent natural background. The situation regarding affirmative, reasonable assurance appears to be this: widespread and frequent observations of DO data which are less than the minimum for Class III waters commonly occur within the existing L-1, L-2, L-3 canals. The increase in depth associated with C-139 is predicted to exacerbate existing stress- es on the DO regime.... However, the SFWMD's response does not constitute reasonable assurance re. other Class III standards. The District's DO and conductivity data may conceivably supply assurances that these standards will be violated in C-139. (Whether background DO and conductivity violate the standards may become important.) The District appears to have two alternatives: 1) attack the Class III standard; 2) apply for variances for, at least, DO and conductivity. A follow-up meeting was held on March 21, 1979. Again, in a file memorandum dated March 28, 1979 Mr. Fields wrote: Consideration of reasonable assurance began at the March 15, 1979, conversation among Messrs. Brown, Davis and Fields. According to the SFWMD, widespread and frequent violations of the Class III water quality standard for dissolved oxygen, as contained in Chapter 17-3, F.A.C., occur throughout the Everglades, in the canals, agriculture areas, Lake Okeechobee, and the conservation areas. The existing borrow canals follow this pattern. The SFWMD alleges that this condition is natural back- ground. They agree that it is probable that any existing DO stresses exist in the borrow canal will be exacerbated in the proposed C-139. However, both the former and present editions of Chapter 17-3 F.A.C. allow for exceptions for natural background. The SFWMD will review these rules to determine which regulatory approach will be taken. In addition, the SFWMD will supply to DER data for the "benchmark" station in the L-28 canal and at Everglades National Park to demonstrate lower back- ground concentrations of DO. Furthermore, the SFWMD will apply, per Ch. 403.087, F.S., for a temporary operating permit for the completed structure. Conditions governing private connections and incor- porating BMPs may be included in the TOP. On April 5, 1979, SFWMD submitted in support of its original permit application a document called Evaluation of Natural Background Dissolved Oxygen in Conservation Area 3-A, South Florida. This evaluation received unfavorable reviews at. DER. Landon P. Ross, chief biologist, wrote in an April 9, 1979 memo that: I have reviewed the data provided by SFWMD regarding background DOs in the Everglades area and have the following comments: Indication that DOs are not harmful to local organisms are, in a legal sense, irrelevant to the question. The data provided give evidence of the occurrence of low DOs in the area. Since the measured low DOs seem to be from artificial drainage channels, they can hardly be supposed to be "natural". The measures that SFWMD provided, however, do not seem too different from the values that I would expect to find in a natural swamp habitat. The proposed "standard" cannot be logically derived from the DO measurements provided. This Evaluation was later submitted in support of first Petition for Exception noted infra. In his review of the data Mr. Fred Bartleson at DER wrote:14/ The data submitted by the South Florida Water Management District does not justify the requested exception for dissolved oxy- gen criteria for the Hendry County Project. The petition alleges that D.O. concentra- tions lower than 1.0 mg/l occur in the re- ceiving waters of Conservation Area 3A. However, the data submitted from that area indicate a minimum value of 2.3 mg/l. The value cited in the petition of less than 1.0 mg/l was recorded in the L-3 borrow canal adjacent to the conservation area. This canal drains an agricultural area. Similar data from the L-28 east canal which is less affected by cultural activity depicts minimum D.O. values between 3 - 2 mg/l. The low D.O. values found naturally in fresh- water wetlands during the warmer months ob- viously result in stress to the biota. The introduction of larger quantities of water from the proposed Hendry County Project, which is anticipated to have lower D.O. values as well as nutrients and pesticides from agricultural runoff, could adversely affect the ecosystem. The proposed exception allowing discharge of water with not less than 1.0 mg/l for more than two consecutive hours in any 24-hour period is arbitrary and not supported by data. It may well be that an exception could be granted for some lowering of the D.O. criteria with time constraints. However, more defini- tive and conclusive data are required to in- sure that this action would not cause adverse effects. The burden of supplying this infor- mation should rest with the petitioner. His views were supported by Messrs. Kevin Edwards, Vernon Myers, and G. J. Thabaraj. Mr. Edwards also noted the difference in DO readings between the WCA- 3A and the borrow canals. SFWMD filed a Petition for an Exception on July 23, 1979. The Petition alleged that the receiving waters of the proposed discharge are located in WCA-3A and that due to natural causes that portion of WCA-3A which will receive the discharge does not meet the state standards for DO as set out in Section 17-3.121, Florida Administrative Code. The DO levels of the proposed discharge are alleged to be similar to those levels already present in the water conservation area. In response to the Petition DER requested more information by a letter from Stephen Fox dated August 29, 1979. The letter requested: Data which supports the contention that the condition of the waters is the re- sult of natural causes, that is, there is an absence of man-induced alteration; or Data which supports the contention that the condition of the waters is the re- sult of man-induced causes which cannot be controlled or abated with technology or management practices. Data which supports the contention that the biota have not been adversely af- fected or will not be affected adversely. The data submitted with the application did not address the possibility that the low dis- solved oxygen levels may be caused by the practice of pumping water off the agriculture areas during the summer wet season. Compari- son with similar subtropical, undisturbed aquatic environment should be made. The dis- solved oxygen data should be compared with pumping schedules and with dissolved oxygen values of water pumped. Comprehensive water- shed and land use data is needed for a thorough review. Further, the data submitted did not support the contention in the petition of a corre- lation between C.A. 3A and canals L-3 and L-28. Also, the contention that in C.A. 3A dis- solved oxygen concentrations were below 1.0 mg/l were recorded was unsupported. The data array was not adequate in terms of distri- bution and frequency of sampling, to demon- strate that the dissolved oxygen regime ap- proaches the proposed alternative criteria. On October 2, 1979, E. D. Vergara summarized the status of the SFWMD application for the DER Secretary, Jacob D. Varn. His memorandum with respect to dissolved oxygen states: ... (permits) originally requested under old 17-3 rules, it was found quality assurances could not be made due to a naturally occurring condition of low DO. The Department requested information sup- portive of the low DO background, but due to differences in opinions among the biologists, the district elected to re- quest an exception under the provisions of the new 17-3 rule instead. Additional information has now been requested by the Department to support the request for an exception, and the District is cur- rently putting this together. It is the general feeling that with this additional data, granting the exception should be possible. SFWMD responded to Mr. Fox's letter above by submitting in the Spring of 1980, an Amended Petition for Exception from Criteria. In its Amended Petition the District abandoned the comparison, found in the original petition, of the proposed discharged waters' dissolved oxygen levels to the levels found in the water conservation district. Instead the District concentrated on a comparison of the dissolved oxygen levels in the proposed discharge waters to the levels in the relatively clean canals in the South Florida area, specifically the L-28 canal system. The District proposed that as an alternative to Class III standards the following criterion be established: During any 24-hour cycle the dissolved oxygen concentration within the photic zone shall exceed 1.0 mg/l, except during the extreme low point when values shall not be less than 1.0 mg/l for more than two consecutive hours. (Emphasis added) Accompanying SFWMD's Amended Petition was a report (Supporting Report) dated February, 1980, which provided a voluminous compilation of data to justify the alternative standard proposed.15/ On April 8, 1980, Ms. Helen Setchfield sent a memorandum to DER staff requesting that they review the Amended Petition and report back to her within five days. Also on April 8, 1980, after a meeting attended by both SFWMD representatives and DER representatives, it was decided that DER would issue coordinated letters of intent on May 5, 1980 for both the exception and the dredge and fill applications. In spite of the decision to issue letters of intent, DER permitting staff were not satisfied with the concept that ban-made canals were "natural" background or that the proposed DO standard was reasonable. On April 16, 1980, Rick Lotspeich wrote to Suzanne Walker, Chief of the Bureau of Permitting, that: I have reviewed the referenced "request for exception" and it appears that the petition and supporting report are suf- ficiently complete to allow evaluation of the merits of the request. It would appear that the proposed dis- solved oxygen standard of 2.0 mg/l over 24 hours and 1.0 mg/l "during the extreme low point" for not more than two hours, is excessively low and not warranted by the data presented. A review of the data from figures 4 and 5 generally indicate that the following standard would be appropriate: Dissolved Oxygen: The concentration should not average less than 4.0 mg/l in a 24-hour period and not less than 3.0 mg/l except during the months of June--September, when the concentra- tion shall not average less than 3.0 mg/l in a 24-hour period and never less than 1.0 mg/l. Later, after having received comments from Rick Cantrell and Bob Siciler, Mr. Lotspeich wrote to Ms. Walker the following: My recollection from reading the request for exception was that SFWMD had indeed recognized the fact that the canals and their design had contributed to the de- pressed DO values of the water in them. Pursuant to Subsection 17-3.031(1), Florida Administrative Code, there may be a consideration for "man-induced causes which cannot be controlled or abated I am in full agreement with Cantrell and Siciler's discussion of the adverse impacts that canals in general, and the specific canal involved in this project, have on water quality and biological resources. However, I disagree with the conclusions that they reached. Clearly, there are extenuating circumstances involved in this case which set it apart from other dredge and fill cases. In light of these circum- stances, the fact that the depressed DO levels have resulted from man-induced causes which cannot be controlled, and Cantrell and Siciler's own statement that approval of this project has little probability of worsening the existing water quality of L-2, L-3 and WCA-3, I would recommend that the exception be granted. However, the alternate DO standard which I recommended in my previous memo is still applicable. (Emphases added. The "extenuating circum- stances" were never explained.) Subsequently, on May 20, 1980, the Department issued a coordinated letter of intent to grant an exception but for the standard proposed by Mr. Lotspeich, not that requested by the Water Management District. Dissolved Oxygen and Exception Section 17-3.121(14), Florida Administrative Code requires that discharges into fresh waters of the state must exhibit dissolved oxygen concentrations of 5.04 mg/l or more. Normal daily and seasonal fluctuations above that level must be maintained. Dissolved oxygen in certain concentrations is required for aquatic life. The amount of oxygen contained in water is subject to numerous variables, many of which are interrelated. They include: amount of sunlight entering the water, ability of the water to transmit light, photosynthetic activity of aquatic plants, water temperature, mechanical oxygenation, mixing with other water which may have either a higher or lower dissolved oxygen content, depth of water, rate of oxygen consumption by resident biota, and time of day. It is undisputed that during certain seasons and times of day the water in the existing borrow canal does not meet the state dissolved oxygen standard. Readings as low as 0.9 mg/l have been obtained there. These low readings usually occur in the months of heavy rainfall, primarily July through September. See the data on Figure 4 of SFWMD's Supporting Report. Similar, though not so low measurements have been obtained in neighboring man-made canals such as L-28. L-28 has been used by water quality experts as a "benchmark" for canal water quality since it does not receive large amounts of runoff from agricultural areas where pollutants such as fertilizers are used. There are numerous times during a given year that the dissolved oxygen levels in L-28 are below the 5.0 mg/l state standard. It is also possible to find at least two locations in WCA-3A wetlands where dissolved oxygen readings are below Class III standards. At Gauge 3-2 in the northwest corner of WCA-3A near where the project would discharge, dissolved oxygen levels have varied from 2.3 mg/l to 10.8 mg/l; however, the mean value for the measured levels has been 5.5 mg/l as reported on Table 2 of the Supporting Report.16/ Unfortunately, the data regarding dissolved oxygen concentrations in the proposed discharge area are scant. This paucity was recognized by the Supporting Report which states at page 6: "No systematic study of the dissolved oxygen conditions or requirements for fresh water wetlands in general, or WCA-3A in particular, have yet been conducted." Despite the limited data on WCA-3A, certain comparisons between DO readings in it and in the borrow canal which would discharge into the area can be made. Readings taken at Gauge 3-2 do not sink to levels as low as those found in L-3. Compare Figure 4 of the Report to Table 2. The minimum readings taken in L-3 were during those periods of greatest discharge. If the discharge from the existing borrow canal were presently sent into the area of Gauge 3-2 during months of peak discharge, the waters entering WCA-3A would have a lower dissolved oxygen concentration than would exist naturally in the area. It is not surprising that water in the borrow canal exhibits unusually low dissolved oxygen levels. The levee sides limit reaeration which could occur due to wind movement. The surface-to-volume ratio is also unfavorable. Much oxygenation occurs at the interface between the water and surrounding air, but because the canal is relatively deep compared to its surface area, the proportion of water coming into direct contact with the air is low.17/ The depth of the photic zone, i.e., the section of water penetrated by light, is limited due to the naturally high color of canal water. Construction of C-139 will add somewhat to a lowering of dissolved oxygen levels in the entire canal water column. To increase its conveyance capacity, the existing borrow canal will be deepened significantly, particularly in its southern reaches. This deepening will result in a lowering of the ratio between the area of water surface to the depth of the canal. No mathematical data were presented by which the lowered ratio can be computed; however, an examination of Plates A-24 and A- 25 of the General Design Memorandum indicates that completed C-139 will contain a higher ratio of water below the photic zone than is presently contained in the borrow canal.18/ This is true only during those times when the canal is relatively full of water. As the canal level drops during a drought the photic zone will approach the canal bottom in the shallower sections. Both SFWMD and DER have proposed site specific DO alternative standards. These have been set out in the foregoing discussion of the permitting history. There is a significant difference between the proposals. SFWMD's proposal includes only the waters contained in the photic zone. It fails to recognize that during times of discharge, the waters of C-139 which are deposited in WCA-3A will not be only those of the photic zone, but will come from the entire water column of the canal. While SFWMD's standard might be acceptable for C-139 when it is in a no discharge state, the standard is completely unacceptable when the canal is discharging. Neither the standard proposed by DER nor SFWMD recognizes the difference between the dissolved oxygen regime which can be predicted for C-139 and that presently existing in WCA-3A. The data submitted would justify an exception from the present 5.0 mg/l Class III standard. There are certainly times when both the water existing in relatively unpolluted canals and in the water conservation area contain less than the present minimal content of dissolved oxygen. When C-139 is not discharging an exception, which would have a range now exhibited by the existing borrow canal, would be justified for the new canal. Sufficient data was not presented here to suggest the precise figures for such an exception. The information given for L-3 for instance, is compiled from samples taken only once during a given day. The water depth of the sample is not given. Accurate data would account for the diel variation and the effect of water depth on each sample. Without data which gives a daily average, it is impossible to determine if the water either standing in, or discharging from C- 139 will meet any proposed alternative criterion. For the same reason the data obtained for the present DO concentrations in WCA-3A is incomplete for establishing appropriate levels for discharge waters entering that area. The establishment of site specific alternative criteria must await the submission of more complete dissolved oxygen readings from the applicant. One of the elements in considering whether to grant an exception to established standards is whether the existing biota have adapted to the background DO levels. The proof here shows that the fish and other biota now living in the borrow canal either tolerate or have adapted to the present low DO regime there. It has also been proven that the biota in WCA-3A are tolerant of the naturally occurring low DO levels in that area. It was not shown how they would respond to a massive influx of low DO water when C-139 would be discharging. Hydroperiod in WCA-3A The northwest corner of WCA-3A, where C-139 and C-139(S) will discharge, has a higher ground elevation than that of the southern portion of the water conservation area. The highest elevation in the extreme northwest corner is approximately 17 feet above mean sea level (MSL). It tapers down to approximately ten feet MSL at the southern boundary of WCA-3A. The project is designed to facilitate the sheet flow of discharge water from the northwest area towards the southeast with an ultimate destination being flow into the Miami canal. The construction of the Miami canal, C-123, which runs on a northwest- southeast diagonal across the area, causes overdrainage of the northwest section. The borrow canal along Alligator Alley also contributes to excess runoff. This overdrainage has shortened the hydroperiod in the northwest corner from approximately 9 to 10 months to approximately 5 to 7 months. "Hydroperiod" is the span of time during which land is inundated by ponded water. The shorten hydroperiod has a profoundly destructive impact on the natural environment. The muck soil when not submerged oxidizes at an accelerated rate. At the present time the rate of oxidation in the northwest corner is more rapid than the replacement rate. Since the natural hydroperiod has been altered muck fires have been more severe and frequent. These fires destroy existing tree islands which dot the Prior to 1974 WCA-3A received discharges from the waters of the L-1, 2 and 3 borrow canal. The outlet of the canal at L-4 was determined to be inadequate for flood control purposes in the L-1 angle. To increase the discharge rate of the borrow canal culverts G-88 and G-89 were installed at the L-3/L-4 intersection in October of 1974. G-89 directs part of the flow from the L-3 canal into canal L-28 west, and then into pumping station 5-140 and into C- 60 (parallel to Alligator Alley). G-88 directs another part of the flow from the L-3 canal into the L-4 borrow canal and then into S-8 where it is pumped into the Miami canal. Rather than being allowed to flow in a shallow sheet across the water conservation area, the direct water flow is now sent southeast in canals for ultimate discharge outside the area. This waste would be eliminated by the proposal to have C-139 discharge into WCA-3A via C-139(S). There is no dispute that more water is needed annually in the northwest corner of the water conservation area. What is at issue here is the timing of placing additional water there. Generally when there is flooding in the L-1 angle and C-139 would be discharging at its maximum rate there is already flooding in WCA-3A. Rainstorm events are somewhat regional and cover both areas. The applicant estimates that if the volume of water discharged by C-139 in a two-week period were to be instantaneously spread over the northwest corner of WCA-3A 20/ it would raise the water stage by 0.4 feet. This would occur during a one in ten year storm. At that time the wildlife in the water conservation area would already be stressed by high water levels. A 0.4 foot increase in stage could kill deer and other terrestrial animals and destroy alligator nests, but it also could benefit the more aquatic animals. The result of this increase cannot be accurately predicted on the data supplied by the applicant.21/ While expert witnesses on behalf of the applicant were willing to express an opinion that the influx of drainage water from C-139 would be beneficial, the opinions were simplistically based on the unsupported assumption that because WCA-3A currently suffers from overdrainage, any additional water at any time would be beneficial. It is possible that those opinions were based on studies conducted which prove that a discharge of water such as will come from C-139 may create a beneficial increase in the marsh hydroperiod. Unfortunately, no evidence of the existence of such studies is in this record. The applicant's expert witnesses' opinions are therefore given little weight. In the present situation WCA-3A receives some water from the borrow canal during the dry season when additional water is most beneficial. At the expense of overdraining the land west of the borrow canal, ground water seepage now enters the canal and travels south through L-1, 2 and 3. After the construction of S-239, designed to prevent overdrainage, any possible flow into WCA-3A during dry periods will be cut off. No evidence was presented on what quantity of water WCA-3A will lose during a dry season due to S-239. Also the record does not reflect what effect that reduction will have on biota in the water conservation area. S-239 and Fill When the level of water in the borrow canal drops below the nearby water table, there is groundwater seepage laterally into the canal. If C-139 were to be constructed without any water control devices, it would exacerbate the overdrainage because it will be a far more efficient conveyance than is the borrow canal. S-239 has been designed to prevent this overdrainage. The structure will be located in Broward County. On May 22, 1979 the County declined to give its approval of the use of any fill, as the term is used in Section 253.124, Florida Statutes, for the construction of this project in Broward County. The Department of Environmental Regulation has not maintained a consistent unwritten policy on what is "fill" in navigable waters of the state.22/ Testimony from past and present Department employees indicated that at times a "use" concept was employed to determine what was fill. If additional dry land were created which would be used for commercial purposes, then the newly created land was called fill which required local approval. At other times use was unimportant. The test was whether or not the result of the additional material would be moving the point, at which the high water mark intersected the land, in a waterward direction. It is found that what constituted fill in past permit cases depended upon the personal interpretation of each Department employee. S-239 as proposed is a massive structure which will cost 1.32 million dollars 23/ to build. It will contain 11,000 cubic yards of fill and backfill; 530 cubic yards of 1' by 1' pieces of stone rip-rap; 1,230 cubic yards of concrete and 647,000 pounds of cement. 153,800 pounds of reinforcing steel will be required. The structure will be over 50 feet high and will span C-139 where it is 60 feet wide. Each of the two vertical lift gates which control the water flow will be 27 feet wide. See Illustration II.* In between them will be a concrete pier three feet wide and approximately 38 feet long. The cement bottom of the structure will rise from an elevation of 8.0 feet MSL to a crest of 3.3 feet MSL for a total height of 11.3 feet. In order to allow service vehicles to pass across the canal a bridge 13 feet wide will span from one bank to the other. This bridge will support large trucks. The stone protection provided for in the plans consists of 1 foot square pieces of rip-rap to be placed 40 feet immediately upstream from the control gates and 30 feet immediately downstream of the gates. The purpose of this protection is to prevent erosion of the canal bottom and sides where the water flows by at a relatively high velocity. The majority of rip-rap will be placed below the ordinary high water mark. Local Water Quality Standards The issue of local water quality standards arose late in the permitting process. DER had already issued two letters of intent to SFWMD before the Department gave consideration to standards promulgated by Broward County. It appears from the record that the Broward County standards were formally brought to DER's attention through the County's Petition for Formal Hearing filed on June 3, 1980. On June 26, 1980, DER issued an amended letter of intent which said: This letter is an amendment of the letter of intent to issue signed by the Department on May 20, 1980. In that letter, the Depart- ment stated: "This intent to issue is contin- gent upon the applicant being granted an exception from the criteria for dis- solved oxygen, for Class III waters, pursuant to Section 17-3.031, Florida Administrative Code." The preceding paragraph is hereby amended to include a provision that the applicant must obtain relief from the dissolved oxygen stan- dards that appear in Section 27-5.072(19), Broward County Code, through a variance or other legal mechanism, in addition to the exception from state standards for dissolved oxygen. Section 27-5.072(19), Broward County Code, states that DO is to have a "daily average not less than 5 mg/l; single reading never less than 4 mg/l. The May 20, 1980, letter also contained a paragraph that read: "However, should the Department grant an exception from the dissolved oxygen criteria pursuant to Section 17-3.031, Florida Administrative Code, the Division intends to issue the permit." This paragraph is hereby stricken and the following paragraph substituted: "If the Department grants an exception from the State dissolved oxygen criteria pursuant to Section 17-3.031, Florida Administrative Code, the Division intends to issue a conditional permit which will only become valid upon the granting of relief by Broward County from its existing local standards for dissolved oxygen." The Department is taking this position upon consideration of Section 403.182(6), Florida Statutes, which requires the Department to en- force all stricter or more stringent rules, regulations or orders in the jurisdiction where they apply. It is the Department's position that it is without discretion to grant relief from Broward County's local standard for dis- solved oxygen. By its Petition the County alleged that it has an approved local pollution control program and that the proposed project will violate its local standards for dissolved oxygen and nutrients found in Sections 27-117(b)(9) and 27-117(11) of the Broward County Code.24/ Neither SFWMD nor the Corps has applied to the Broward County Environmental Quality Control Board for either a license under Chapter 27 of the County Code or for a variance from the standards established therein. On April 20, 1972, the Florida Department of Pollution Control (the predecessor of the Department of Environmental Regulation) gave temporary and conditional approval for six months to the Broward County Pollution Control Program. This approval provided that the County has full authority to enforce its own laws, rules and regulations, provided that they must be as strict or stricter than those of the State. The County was also required to modify its rules if the State subsequently adopted the regulations in conflict with those of the County. On November 7, 1972, the Department of Pollution Control gave Broward County full and final approval pursuant to Section 403.182, Florida Statutes. Subsequently, in 1974 and 1976 the State and Broward County entered into new agreements. These agreements were the result of DER's desire to make uniform all its agreements with all qualified local programs. The Broward County pollution control program including the portion administered by the Environmental Quality Control Board, continues to be an approved local program as defined at Section 403.182, Florida Statutes.
