Findings Of Fact Based on the testimony of the witnesses and their demeanor while testifying, the documentary evidence introduced, the proposed findings of facts and recommended orders filed by the parties' counsel, and the arguments and citations of authority cited therein, the following relevant facts are found. 1/ This action concerns a parcel of land owned by Ronald E. Dowdy and his wife, Mary Ellen Dowdy, located at 7630 Lake Marsha Drive, Orlando, Florida. The Department does not claim, other than regulatory authority, ownership to the land in question. On March 15, 1978, Petitioner submitted to the Department a dredging and fill permit application, file No. 48-8093-4E., to deposit 200 cubic yards of fill material waterward of the line of ordinary high water, adjacent to Petitioner's upland property on Lake Marsha. The area proposed to be filled measured 150 feet along the shoreline, 55 feet between the line of ordinary high water and ordinary low water, and 12 inches deep. (Petitioner's Exhibit 2; D.E.R. Exhibit 9.) On June 15, 1978, the Department gave notice of its intent to deny Petitioner's permit application, stating with particularity the specific ground on which the denial was based and allowing Petitioner fourteen (14) days in which to petition for a hearing on the denial. Within thirty (30) days of the filing of the petitioner's application, he was advised that clearance and/or approval was necessary from the Department of Natural Resources. A Final Order denying application for permit was issued June 23, 1978. Petitioner did not file a petition pursuant to Chapter 120, Florida Statutes, seeking review of either the intent to deny letter or the Final Order until January 15, 1979. The Department waived the time requirement for filing the petition. On or about August 3, 1978, Petitioner caused to be deposited large quantities of fill in excess of the 200 cubic yards applied for along approximately 380 feet of shoreline between the line of ordinary high water and ordinary low water adjacent to his upland property. (Petitioner's Exhibit 2 and D.E.R. Exhibits 1 and 2.) Although Petitioner did not obtain a permit from the Department prior to commencement of the fill work described above, Orange County issued a permit (see Petitioner's Exhibit 2) which specified that the Department permit would have to be obtained prior to commencement of the fill work. The county permitted the Petitioner to fill an area along 150 feet of shoreline while the petitioner filled the entire length of the shoreline, i.e., 380 feet. As of the hearing date, Petitioner had not filed an application for a permit from either the county or the Department for the excess fill. Prior to the time that the Petitioner undertook the filling project, he met with employees of the Department who advised that a permit would be necessary prior to commencing the fill work. Department employees suggested that the State would look favorably on a reduced fill project of somewhere between 50 to 75 feet along the lake shoreline. (D.E.R. Exhibit 8.) The bulk of the fill area as completed, lies below the ordinary high water line of Lake Marsha, i.e., below the elevation line of 127 feet. (Petitioner's Exhibit 2.) Mr. Robert Day, a pollution control specialist employed by the Department as an enforcement investigator, observed the filling activity as it was taking place from the movement of fill by bulldozer to the sodding of the newly created fill area. (D.E.R. Exhibits 1 and 2.) Upon discovery of the Petitioner's filling activity without a permit, the Department attempted to notify him of the violation by means of a warning notice sent by U.S. Mail, certified, return receipt requested, which Petitioner did not claim. The Department thereafter sent Petitioner a telegram which resulted in a meeting in the Department's office in Orlando. (D.E.R. Exhibits 3, 4 and 5.) Richard Hoffman, district conservationist with the U.S. Department of Agriculture, Soil Conservation Service, was qualified as an expert in the collection and identification of soil core samples. Mr. Hoffman testified at length on a series of core samples taken on the Dowdy property confirming the fact that the Petitioner had placed fill on vegetated muck and that all but one of the core samples were below the high water line. (Petitioner's Exhibit 2 and D.E.R. Exhibit 7.) James Morgan, an environmental specialist of the Department, was qualified as an expert witness in the processing and appraisal of dredge and fill permit applications and their impact on water quality and wetlands ecology. Mr. Morgan advised the Petitioner on February 14, 1978, several months before the actual filling activity, that it was necessary to obtain a permit from the Department pursuant to Chapter 17-4, Florida Administrative Cede. Again, on March 16, 1978, at a meeting with Petitioner, Mr. Morgan advised the Petitioner of the necessity to obtain a permit before any filling was done. Additionally, he advised and suggested to Petitioner that with respect to his proposed activity, the Department would look favorably upon a modified application requiring a fill area of 50 to 75 feet of the lake's shoreline. Upon receipt of Petitioner's application, Mr. Morgan conducted a permit application appraisal (D.E.R. Exhibit 9) and found that the area proposed to be filled contained deep muck deposits and was dominated by the vegetation, maidencane, with a lesser abundance of arrowhead, pickeral weed and pennywort. The dominant species was maidencane, which along with arrowhead and pickeral weed, are species found in the vegetative index for submerged lands as set forth in Section 17-4.02(17), Florida Administrative Code. (See D.E.R. Exhibits 9 and 10.) Approximately 50 percent of the shoreline of Lake Marsha has been developed with the consequent elimination of marsh and wetland vegetation fringes of the lake. The aquatic vegetation found on the Dowdy property prior to filling performed functions of assimilating nutrients and filling deleterious substances from the waters of Lake Marsha and provided wildlife habitat. This assimilation process enabled and assisted the shoreline plants ability to absorb water containing dissolved pollutant substances which are utilized for plant food. The aquatic vegetation also filters suspended solids from the lake water. This assimilation and filtration process helps preserve water quality in a fresh water lake by both filtering runoff from the upland and cleansing the water of substances found in the water body itself. (D.E.R. Exhibit 9.) This process is commonly referred to as the "kidney effect". The fill which has been placed in the submerged land aquatic community will, as testified by the Department's witnesses, totally eliminate portions of the kidney of Lake Marsha and has been replaced with sod which carries the potential for causing further pollution of the waters of Lake Marsha. Testimony reveals that the fill will increase the nutrient load in the lake and dramatically decrease its ability to cope with the increased load. It is predicted by the Department's witnesses that the impact of the fill on the water quality of the lake will be significant as a substantial portion of the lake's littoral zone has been substantially eliminated. This, according to witness Morgan, can lead to the eutrophication of Lake Marsha end a resultant lower equilibrium based on poor water quality. (D.E.R. Exhibit 11.) According to Morgan, the parameters which are expected to be violated by the fill and the resultant elimination of a submerged land aquatic plant community include phosphorous and nitrogen which are classified as nutrients under Section 17-3.061(2)(i), Florida Administrative Code, and turbidity, under Section 17-3.061(2)(g) Florida Administrative Code. (D.E.R. Exhibit 9, part 2.) Testimony reveals that a correlation exists between the degree of shoreline development of Central Florida lakes and the water quality of such lakes. This correlation is direct and reveals that the greater the degree of shoreline development, the greater the reduction of the lake's ability to compensate for nutrient load going into the lake and, thus, lower water quality. (Testimony of Morgan and Hulbert, T.R. pp 138-139; 177-180.) Witness Morgan testified that by restoration of the Petitioner's fill site to its original contours and elevation, the aquatic vegetation which once thrived on the site will reestablish itself and the consequent restoration of the lake's "kidney effect". James Hulbert, a Department District Biologist qualified as an expert in the area of water pollution biology and wetlands ecology, confirmed witness Morgan's testimony regarding the impact of water quality based on Petitioner's filling, the value of the wetland vegetational community which was, according to him, destroyed by the filling, including protection of uplands and its role as a source of food and shelter for the lake's aquatic life. Witness Hulbert also confirmed the testimony of witness Morgan to the effect that a direct correlation exists between the degree of shoreline development in central Florida lakes and the lowering of water quality in such lakes. Witness Hulbert testified further that submerged lands such as the ones filled by Petitioner assimilate nutrients for preserving fisheries of fresh water lakes. Mr. Hulbert also testified that dissolved oxygen levels are expected to be degraded with severe fluctuations which would result in the dissolved oxygen levels of as low as 0.0, below the standards of Chapter 17-3, Florida Administrative Code. This increased nutrient load will, according to Mr. Hulbert, result in proliferation of such existing exotic plant species such as hydrilla and water hyacinths, and an acceleration of the lake's eutrophication. Mr. Hulbert summarized the long- range impact of the fill as both measurable and substantial and concluded that the degradation process will be steady and gradual. Robert Bell, a real estate appraiser licensed in the State of Florida as a broker, indicates that there are other valuable uses of Petitioner's property other than filling the entire shoreline. Such uses, according to Bell, include the construction of a boardwalk, a deck, gazebo, a boat house, and even partial filling of the shoreline area for access to the water. The Department incurred expenses and costs in preparation of this proceeding for purposes of tracing, controlling, and abating the pollution sources created by the Petitioner's dredge and fill activities in the amount of $201.88. (D.E.R. Exhibits 14 and 15.)
Recommendation Based on the foregoing findings of fact and conclusions of law, it is hereby
Findings Of Fact The Respondent owns property in Lake County, Florida which adjoins North Lake Holly. North Lake Holly is a fresh water lake. On an undetermined date between December, 1975 and September, 1976, the Respondent caused a horseshoe-shaped basin to be dredged along the shoreline of North Lake Holly adjoining his property. The fill material taken from the dredged area was deposited along the shore of the lake to farm a beach. The basin is approximately 90' long, 50' wide, and 6' deep. The Respondent has erected a dwelling house on his property, and it appears that the dredging was done in order to transform the shoreline of the lake from a vegetated littoral zone to a beach and boat basin. The Department confirmed the violations in December, 1976, and sought to negotiate a restoration plan with the Respondent. The formal Notice of Violation was issued an November 17, 1977. The dredged area was previously a shallow littoral zone dominated by wetlands vegetation. The most prevalent vegetation was sawgrass, but there were also abundant quantities of cattails, maidencane, arrowhead, and willows. The dredging activity relates to only a small portion of the shoreline of North Lake Holly. The activity nonetheless has resulted in the alteration of the characteristics of the lake. The marsh area which fringes the lake serves as habitat for fish and other wildlife, and also serves to filter runoff which enters the lake from the uplands. The Respondent's activities have obliterated a portion of the wildlife habitat, and provide an avenue for some uplands runoff to be discharged directly into North Lake Holly without the benefit of being filtered through wetlands vegetation. The quality of waters in central Florida lakes is related directly to the amount of development along the shoreline. The greater degree of alteration of the shoreline, the greater degree of deterioration of water quality, and the greater the deterioration of wildlife habitat. A project of the magnitude of that accomplished by the Respondent may have no clearly measurable impact upon water quality and wildlife habitat since the rest of North Lake Holly is surrounded by a broad littoral zone. The only impact that the project can have is, nonetheless, adverse. If a project such as the Respondent's is approved, the Department could not, consonant with due process and equal protection concepts prohibit further such alterations of the shoreline. It is likely that some aquatic vegetation will reestablish itself along the shoreline of the dredged area. Such a natural restoration will not, however, alleviate the negative impacts of the Respondent's dredging. The steep inclines of the dredged area will allow only a very narrow rim of vegetation, which cannot be expected to provide habitat and protect water quality to remotely the extent of the, previous undisturbed broad littoral zone. Furthermore, in the time since the project was completed, no significant vegetative zone has reestablished itself. It is possible for the Respondent to gain access to the lake for boating and other recreational purposes without totally obliterating the littoral zone that was in the area. The Department has offered a restoration plan which would accomplish this result. The Respondent undertook the dredge and fill activity without seeking a permit from the Department, and he continues to operate what amounts to a stationary installation which will serve as a source of pollutants to North Lake Holly without any valid permit issued by the Department. The Department has spent $229.41 in assessable costs in investigating and attempting to rectify the illegal dredge and fill activity undertaken by the Respondent.
The Issue The issues to be determined in this proceeding are: whether the challengers have standing; and (2) whether Proposed Rule 40E-8.221(2) is an invalid exercise of delegated legislative authority.
Findings Of Fact Based on the parties' stipulations and the evidence adduced at the final hearing, the following findings of fact are made: The Parties The District is a government entity existing and operating pursuant to chapter 373, Florida Statutes, as a multi- purpose water management district. The District has the power and duty to adopt MFLs consistent with the provisions of part I of chapter 373. Sanibel is a barrier island sanctuary in Lee County and a duly-formed municipality with a population of more than 6,000. Sanibel is situated at the mouth of the Caloosahatchee River, within the Caloosahatchee's greater estuarine area. Sanibel is known primarily for its natural beauty, including clear blue waters, shell beaches, world-class sport fisheries, and wildlife refuges. That is why tourists come from around the globe to visit Sanibel, and why Sanibel's residents move and remain there. Sanibel actively participated in the rulemaking process for the Proposed Rule from its inception. Sanibel submitted two technical comment letters to the District during the development of the Proposed Rule. Sanibel's natural resources director, James Evans, attended numerous public and technical meetings associated with the development of the Proposed Rule, speaking on the record at each of the public meetings prior to the adoption hearing by the District's governing board. The Town, located on Estero Island in Lee County, is also a barrier island community and duly-formed municipality with a population of more than 6,000. The Town is situated just south of the mouth of the Caloosahatchee River and on the southeastern edge of the Caloosahatchee River's greater estuarine area. The Town is known primarily for its natural beauty, including clear blue waters, shell beaches, world-class sport fisheries, and wildlife refuges. Cape Coral is a duly-formed municipality in Lee County and is the largest city between Tampa and Miami, with a population in excess of 150,000. Cape Coral is bordered on the south by the Caloosahatchee River and has over 400 miles of navigable canals and waterways, all of which are within the Caloosahatchee River's greater estuarine area. In addition, Cape Coral has an assigned load reduction allocation under the Basin Management Action Plan (BMAP) for the Caloosahatchee River Estuary (CRE) due to it being designated as impaired for dissolved oxygen and nutrients. Maintaining sufficient flow in the Caloosahatchee River would have a direct impact on Cape Coral's ability to meet its assigned load reduction allocation. In addition to living on or near the water, a substantial number of the residents of Sanibel, Cape Coral, and the Town engage in water-based recreational activities such as swimming, fishing, boating, kayaking, paddle boarding, bird watching, and nature observation in and around the Caloosahatchee River's greater estuarine area. Fort Myers is a duly-formed municipality in Lee County and has a population of approximately 80,000. Fort Myers is bordered by the CRE throughout its entire jurisdictional boundary. Fort Myers owns and maintains a yacht basin (Ft. Myers Yacht Basin), which includes a mooring field and an anchorage field in the Caloosahatchee River. Fort Myers presented testimony that commercial crabbing and recreational fishing have declined and that it has suffered economic harm due to water quality issues. Fort Myers owns the submerged land in the Caloosahatchee River from Marker 39 to Marker 58, and islands in the river. One such island will be used as a park for recreational activities such as canoeing, kayaking, and hiking for visitors to enjoy the Caloosahatchee River. Fort Myers also owns and operates piers and a public boat ramp within the Caloosahatchee River. Fort Myers' dock master has observed declines in seagrasses in the Caloosahatchee River during his 19-year career working at the Ft. Myers Yacht Basin. Fort Myers has adopted a Harbor Management Plan for the management of its mooring and anchorage fields in the Caloosahatchee River. Fort Myers has also been assigned a load reduction allocation under the BMAP for the CRE, and is responsible for a certain amount of pollution reduction over time. Bonita Springs is a municipality of more than 50,000 in Lee County. The borders of Bonita Springs include portions of Estero Bay, which, along with San Carlos Bay and the Caloosahatchee River, is part of the greater Lower Charlotte Harbor Estuary. Bonita Springs includes wildlife refuges, such as the Estero Bay Aquatic Preserve and Lovers Key State Park and Recreation Area. While Bonita Springs' strategic priorities include environmental protection and water quality, it does not have environmental staff or test water quality. Bonita Springs participates in Estero Bay Management and the Charlotte Harbor National Estuary Program (CHNEP). Bonita Springs provides financial assistance to the Caloosahatchee Citizen Sea Grass Gardening Project. Concerns regarding harm to the CRE and tape grasses are shared by a significant number of residents in Bonita Springs and Estero, including injury to the quality of life and recreational uses such as swimming, boating, and kayaking in the waterways. Estero is a municipality of more than 30,000 in Lee County. Estero borders the eastern portion of Estero Bay. Estero includes wildlife refuges, such as Estero Bay Aquatic Preserve and Koreshan State Park. While Estero has environmental policies, it does not have environmental staff or test water quality. Estero makes financial contributions to CHNEP. Estero is concerned that the Proposed Rule will affect its water quality, which could affect its residents' quality of life. Estero believes it could be harmed by poor water quality because its residents are portable retirees who can move away, or tourists who can choose not to visit. Captiva Island is situated at the mouth of the Caloosahatchee River, within the Caloosahatchee's greater estuarine area. CCP is a Florida not-for-profit corporation representing property owners, businesses, and the community of Captiva Island. Captiva Island is part of unincorporated Lee County and is located north of Sanibel. CCP has 200 financial contributors comprised of property owners, businesses, and residents on Captiva Island. CCP's mission includes protection of clean off-shore water, diverse and healthy marine life, and robust native vegetation along with the protection of mangrove fringe and water quality. CCP works with Lee County on provisions of the County's comprehensive plan, which include the quality of adjacent waters. CCP relied on the expertise of James Evans, the director of natural resources for Sanibel, and on the Sanibel- Captiva Conservation Foundation (SCCF). CCP was advised that the Proposed Rule was not sufficient to protect the environment and Vallisneria americana (Vallisneria) or tape grass during the dry season. Caloosahatchee River and Estuary The watershed of the Caloosahatchee River covers approximately 861,058 acres. The watershed consists of four sub-watersheds, three of which are upstream of the S-79 structure. The Tidal Caloosahatchee Basin sub-watershed (estuarine system) is downstream of the S-79 structure. The S-79 structure captures all the upstream discharges of fresh water that go into the estuarine system through the S-79 structure. Major tidal tributaries of the Tidal Caloosahatchee Basin are the Orange River and Telegraph Creek, which drain into the upper estuary downstream of the S-79 structure. Fresh water inflows from these and other tributaries also contribute fresh water into the estuarine system. The Caloosahatchee River was originally a natural watercourse running from its origin at Lake Flirt to San Carlos Bay. It is currently defined as the "surface waters that flow through the S-79 structure, combined with tributary contributions below S-79 that collectively flow southwest to San Carlos Bay." Fla. Admin. Code. R. 40E-8.021(2). Man-made alterations to the Caloosahatchee River began as early as 1884, but major alterations began in the 1930s with the authorization and construction of the C-43 Canal. The C-43 Canal runs 41.6 miles from Lake Okeechobee at Moore Haven, i.e., from the S-77 structure, to Olga, i.e., the S-79 structure. The C-43 Canal serves as a conveyance feature to drain water from the three sub-watersheds located upstream of the S-79 structure and convey regulatory discharges of water from Lake Okeechobee. In 1957, the United States Army Corps of Engineers (USACOE) prepared a report focused on drainage, flood control, and navigation needs of the Caloosahatchee River Basin, and one recommendation was construction of the S-79 structure. The key objectives of the S-79 structure were to eliminate undesirable salinity in the lower Caloosahatchee River, prevent the rapid depletion of water supplies, and raise the prevailing dry weather water table levels. The S-79 structure was constructed in 1965. It is a lock and dam structure that is also known as the Franklin Lock and Dam. The S-79 structure captures all upstream fresh water discharges that go into the CRE. The S-79 structure demarcates the head of the CRE, which extends 26 miles downstream to Shell Point, where it empties into San Carlos Bay in the southern portion of the greater Lower Charlotte Harbor Estuary. Most of this surface water flow takes a southerly route, flowing to the Gulf of Mexico under the Sanibel Causeway that crosses San Carlos Bay. When fresh water inflows are high, tidal action pushes some of this water back up into Matlacha Pass and Pine Island Sound. Additionally, some water exits to the south and flows into Estero Bay through Matanzas Pass. Salinity exhibits a strong gradient in the CRE. Changes in the watershed upstream of the S-79 structure have profoundly influenced the delivery of fresh water to the CRE. Runoff is now more variable with higher wet season flows and lower dry season discharges. Large volumes of fresh water during the wet season can flush salt water from the tidally-influenced sections of the water body, resulting in low salinity conditions throughout most of the CRE. In contrast, fresh water inflow at the S-79 structure can stop entirely during the dry season, especially during significant drought events. This results in saline intrusion that can extend upstream to the S-79 structure. Fluctuations of this magnitude at the head and mouth of the system cause mortality of organisms at both ends of the salinity gradient. Downstream of the S-79 structure, the CRE was significantly altered by multiple dredging activities, including the removal of extensive shoals and oyster bars. Seven automobile bridges, a railroad trestle, and the Sanibel Causeway were built between the 1880s and 1960s. A large canal network was built along the northern shoreline of the CRE in Cape Coral. To provide navigational access from the canal network to deeper water, multiple access channels were dredged within the CRE. Alterations to the delivery of fresh water combined with structural changes to the tidally-influenced sections of the water body have had lasting ecological consequences. These include the loss of extensive shoals and oyster bars, loss of a flourishing bay scallop fishery, and significant decline in seagrass cover in deeper areas. MFLs An MFL is the limit at which further withdrawals would be significantly harmful to the water resources or ecology of the area. The District's rules define significant harm as the "temporary loss of water resource functions, which results from a change in surface or ground water hydrology, that takes more than two years to recover, but which is considered less severe than serious harm." Fla. Admin. Code R. 40E-8.021(31). The rule further specifies that a water body's specific water resource functions addressed by an MFL are defined in the MFL technical support document. Id. MFLs are calculated using the best information available. The regulatory agency is required to consider changes and structural alterations to watersheds, and the constraints such changes or alterations placed on the hydrology of an affected watershed. Certain waterbodies may not serve their historical hydrologic functions and recovery of these waterbodies to historical hydrologic conditions may not be economically or technically feasible. Accordingly, the regulatory agencies may determine that setting an MFL for such a water body based on its historical condition is not appropriate. Caloosahatchee MFL For the CRE, MFL criteria were designed to protect the estuary from significant harm due to insufficient fresh water inflows and were not guidelines for restoration of estuarine functions to conditions that existed in the past. The MFL criteria consider three aspects of the flow in terms of potential significant harm to the estuary: (1) the magnitude of the flow or the volume of fresh water entering the estuary; (2) the duration of time that flows can be below the recommended level before causing significant harm; and (3) the return frequency, or the number of times the MFL can be violated over a number of years before it results in significant harm, recognizing that natural climatic variability will be expected to cause fresh water inflows to fall below recommended levels at some natural frequency. The CRE MFL initially adopted in 2001 was primarily based on the salinity tolerance of one valued ecosystem component (VEC). The VEC was Vallisneria americana or tape grass, a fresh water aquatic plant that tolerates low levels of salinity. A major assumption of this approach was that flow and salinity conditions that protect Vallisneria would also protect other key organisms in the estuary. The 2001 CRE MFL was based on a regression model for estimating the relationship between surface salinity measured at the Ft. Myers monitoring station located in the Ft. Myers Yacht Basin and discharge at the S-79 structure. Although the District monitors surface and bottom salinity at multiple stations in the CRE, the Ft. Myers monitoring station is located centrally in the CRE and at the historical downstream extent of the Vallisneria habitat. The Ft. Myers monitoring station also has the most comprehensive period of record of monitoring data available. The fixed data sondes that monitor surface and bottom salinity are located at 20 percent and 80 percent of total river depth measured at mean low water. The data sondes continuously measure temperature and specific conductivity and, depending on the manufacturer, contains programs that calculate salinity. Those calculations are based on standards recognized and used worldwide by estuarine, marine, and oceanographic scientists.1/ The regression model only implicitly included inflows from the Tidal Caloosahatchee Basin sub-watershed downstream of the S-79 structure. To address this, during the 2003 re-evaluation, a linear reservoir model of Tidal Caloosahatchee Basin inflows was developed. The regression model results showed that a total inflow from S-79 plus the Tidal Caloosahatchee Basin of about 500 cubic feet per second (cfs) was required to produce a salinity of 10 at the Ft. Myers monitoring station. Thus, the 2001 CRE MFL of 300 cfs measured at the S-79 structure would produce a salinity of 10 at the Ft. Myers monitoring station only with additional inflow from the downstream Tidal Caloosahatchee Basin sub- watershed. However, that additional inflow estimate was highly uncertain. The conclusion was that actual flow measurements over a period of time were needed in order to perform more robust calibrations for the new models that were being developed. The Re-evaluation The District's re-evaluation effort began in 2010 after the Conservancy of Southwest Florida filed a petition requesting review of the Caloosahatchee MFL. At the time, the governing board denied the petition but directed staff to undertake additional research and monitoring to ensure a future revision would be supported by the best information available. The first step was to review the September 2000 Final Peer Review Report (PRR) for the initial adoption. The 2000 PRR identified several items the District should consider, including a hydrodynamic salinity model, a numerical population model for Vallisneria, quantification of habitat value for Vallisneria, and documentation of the effects of minimum flows on downstream estuarine biota. The 2000 PRR documented concerns that the current MFL was based solely on the salinity tolerance of Vallisneria and recommended using multiple indicator species. To address those recommendations, the District conducted studies to evaluate multiple ecological indicators, such as zooplankton, aquatic vegetation, oysters, benthic communities, and blue crabs, in the Caloosahatchee from the S-79 structure to beyond Shell Point. In addition, the District collected flow data from the Tidal Caloosahatchee Basin sub-watershed for at least five years to develop watershed, flow, and hydrodynamic models that could properly simulate inflows and salinity responses. When the initial research was complete in 2016, the District published the Draft Science Document containing 11 component studies. In September 2016, the District held a two- day Science Symposium to present the 11 component studies and gather public comment. In response to public comment, the District performed additional evaluations, modeling, and updated the component studies to produce a Draft Technical Document. A Peer Review Panel reviewed the Draft Technical Document, which included the Draft Science Document. The Peer Review Panel has over 150 years of combined relevant scientific experience. The Peer Review Panel toured the CRE by air and water. The District also held a Peer Review Session to engage the public and obtain feedback. The Peer Review Panel's 2017 report (PRP report) stated that the District had "crafted a well-executed and well- documented set of field and laboratory studies and modeling effort" to re-evaluate the CRE MFL. The PRP report supported the 11 component studies, the modeling, the evaluations, and the initial proposed rule language. The Final Technical Document published in January 2018 incorporated five different models and additional science, examining the entire watershed and the criteria itself. The Final Science Document was Appendix A to the Final Technical Document and contained the scientific research and analysis that was done for the 11 component studies, the modeling, and the additional scientific analyses performed in response to public and stakeholder input. The District initiated rule development in December 2017. Rule development workshops were held in February and June 2018 and a stakeholder technical meeting was held in May 2018. The District validated the comments after each workshop and meeting, and revised the proposed rule language. The District published its Notice of Proposed Rule on July 23, 2018.2/ At its September 13, 2018, meeting, the District's governing board held a public hearing on the Proposed Rule. The mayors of Sanibel, Cape Coral, and the Town publicly commented at the hearing. After considering public comments, the governing board adopted the Proposed Rule. The District documented and responded to each public comment, memorializing the information in the Final Technical Document. Later, after the rule workshops and May 2018 technical meeting, the District prepared and presented all of the updated information, including public comment, at the September 2018 adoption hearing. Thus, the District's re-evaluation process was open and transparent. The Re-evaluated Caloosahatchee MFL The science supporting the re-evaluation involved a comprehensive assessment of the effects of diminished dry season fresh water inflows on the CRE. The dry season was chosen for two reasons. First, because it is well-established that the upstream migration of salt combined with reduced fresh water inflow alters the health and productivity of estuarine habitats. Second, because the dry seasons are the times when the current MFL criteria are likely to be exceeded or violated. The 11 component studies targeted specific concerns regarding physical and ecological characteristics. Together they offered a holistic understanding of the negative effects of diminished fresh water inflow on estuarine ecology. The re-evaluated MFL criteria were developed using a resource-based approach. The approach combined the VEC approach and the habitat overlap concept. The habitat overlap approach is based on the idea that estuaries serve a nursery function and salinity determines the distribution of species within an estuary, including distribution during different life stages. The combined approach studied the minimum flow requirements of the various indicator species in terms of magnitude, duration, and return frequency, resulting in the following three aspects of the flow: (1) for magnitude, a 30-day moving average flow of 400 cfs measured at the S-79 structure; for duration, an MFL exceedance occurs during a 365-day period when the 30-day moving average flow at S-79 is below 400 cfs and the 30-day moving average salinity exceeds 10 at the Ft. Myers salinity monitoring station; and (3) for return frequency, an MFL violation occurs when an exceedance occurs more than once in a five-year period. The magnitude component is based on the salinity requirements of Vallisneria, along with results from the 11 studies modeling salinity and considering the salinity requirements of the other VECs. The duration component is based mainly on the estimates of rate of loss of Vallisneria shoots when salinity rises above 10 and the recovery rate of the shoots when salinities fall back below 10. Return frequency was determined based on long-term rainfall records rather than flow measurements from the S-79 structure, which the PRP report felt was well justified. In addition to the component studies, the re-evaluated MFL criteria and existing recovery strategy were evaluated using a suite of hydrologic and ecological models simulating long-term fresh water inflow to the CRE associated with varying management options, the resulting salinity in the CRE, and the ecological response of indicator species that are sensitive to low fresh water inflows. Five models were utilized. Three models simulated fresh water inflows to the CRE: two for S-79 flows; and one for Tidal Caloosahatchee Basin sub-watershed flows. The other two models were a three-dimensional hydrodynamic salinity model and a Vallisneria model. Tidal Caloosahatchee Basin sub-watershed has a number of tributaries that drain fresh water into the CRE. The flow at several of the tributaries was monitored for a five-year period. The measured flow was used to calibrate a watershed model and conduct a long-term simulation. The results showed an average fresh water inflow for all seasons of approximately 430 cfs. The average fresh water inflow during the dry season was 245 cfs while the wet season average fresh water inflow was 613 cfs. Fresh water inflow from the Tidal Caloosahatchee Basin sub- watershed was approximately 20 percent of total fresh water inflow to the CRE while 80 percent was released through the S-79 structure. Petitioners' and Intervenors' Objections 400 cfs Is Too Low Sanibel relied on a memorandum prepared by Dr. David Tomasko (Tomasko report) concerning his company's review of the January 2018 Final Technical Document supporting the Proposed Rule. The Tomasko report, dated October 23, 2018, was in the form of a "technical memorandum" outlining "preliminary findings." The Tomasko report was admitted as a joint exhibit; however, Dr. Tomasko did not testify at the final hearing. The Tomasko report is hearsay that was not used to supplement or explain competent direct evidence. Although hearsay is admissible in this proceeding, it cannot be the sole basis for a finding of fact.3/ See § 120.57(1)(c), Fla. Stat. The District's expert witnesses, who testified at the final hearing, explained that ten of the 11 component studies identified average indicator flows at S-79 ranging from 237 to 545 cfs with standard deviations ranging from plus or minus 57 to plus or minus 774 cfs.4/ The District's experts performed three different evaluations of those flow results. They identified the mean of all the means, calculated the median of the means, and performed a probability density function. The flow results for each of the three evaluations were 381 cfs, 400 cfs, and 365 cfs, with standard deviations that ranged from plus or minus 277 cfs to plus or minus 706 cfs. The District's experts testified that the three flow results are indistinguishable from a statistical point of view. The District chose 400 cfs because it was the highest flow result, and, therefore, the most protective of the three. The Petitioners and Intervenors failed to present evidence that showed any deficiencies in the District's component studies, hydrologic, hydrodynamic, or statistical modeling, or analysis of compliance data. The preponderance of the evidence established that the District used the best available science to calculate the MFL criteria. The District did not act arbitrarily or capriciously when it chose 400 cfs as the magnitude component of the MFL criteria. Inclusion of Salinity in the MFL Criteria The preponderance of the evidence also established that Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE. It supports essential ecological goods and services, is sensitive to salinity fluctuations at the ecosystem scale, and has value to a variety of stakeholders. The location of Vallisneria habitat in the upper CRE and its negative response to increased salinity made it an excellent candidate as an ecological indicator for fresh water inflow. A combination of field monitoring, mesocosm studies, and modeling results allowed the application of Vallisneria responses as a platform to quantify the effects of high salinity duration in the upper CRE. Component Study Eight reviewed the development and initial application of a simulation model for Vallisneria in the CRE. The Vallisneria model was used to evaluate the salinity conditions that led to net annual mortality, or, in other words, the duration of high salinity exposure that led to decreased Vallisneria shoots versus the duration of low salinity conditions required for recovery. Component Study Seven included an analysis of the relationship between the number of consecutive days where salinity at the Ft. Myers monitoring station was greater than 10 and the percentage of initial Vallisneria shoots remaining at the end of each high salinity period. To further evaluate the duration element associated with the MFL criteria, the field monitoring data contained in Component Study Seven was evaluated with the mesocosm and modeling results. All three sources were analyzed similarly to derive a combined curve showing high salinity exposure duration that is significantly harmful to Vallisneria. The model also provided information that was used to quantify the duration of low salinity conditions required for Vallisneria to recover a relative fraction of shoots after high salinity exposure. Merging the exposure and recovery evaluations facilitated a determination of the unfavorable salinity duration that could significantly harm Vallisneria habitat. With significant harm defined as the environmental harm from which two years are required to recover, the determination was that Vallisneria should experience no more than 55 consecutive days of salinity greater than 10. However, stakeholders expressed concerns regarding the percentage loss of Vallisneria habitat after 55 days of high salinity exposure. In response, the District conducted further analysis of modeling results and revised the duration component to accept the stakeholder recommendation, now expressed in the Proposed Rule, of a 30-day moving average salinity greater than 10. The Petitioners and Intervenors argued that by expressing the MFL as a "flow plus salinity component" the Proposed Rule enlarges, modifies, or contravenes the specific provisions of law implemented. However, the duration component is part of compliance and represents the duration of time that flows can be below the recommended level before causing significant harm to the indicator species Vallisneria. The MFL in the Proposed Rule is a 30-day moving average flow of 400 cfs measured at the S-79 structure. Flow is both measured and operationally controlled at the S-79 structure. However, as previously found, there are other sources of fresh water entering the CRE downstream of the S-79 structure. The District does not control and cannot control these downstream sources, which modeling reveals contribute approximately 20 percent of total fresh water inflow to the CRE. By including salinity, the District can account for fresh water inflows coming from the tidal basin when there are low or no flows at S-79 since the significant harm threshold in the CRE is directly related to salinity tolerance of the indicator species Vallisneria. The District's experts also testified that salinity can be used as a flow component because it is not affected by chemical or biological processes and is an indicator of how much fresh water is entering the system.5/ Salinity is included in the duration component of the MFL criteria and is an exceedance criterion because the science established that the salinity gradient is crucial to the overall health of the CRE. Including salinity in the duration component of the MFL criteria achieves the purpose of the statutory mandate to set MFLs that are designed to avoid significant harm to the water resources and ecology of the area. No Unit of Measurement for Salinity The Petitioners and Intervenors argued that the Proposed Rule is vague because the language does not contain any units for salinity. The UNESCO calculation is the standard equation used by the estuarine and marine science community to convert specific conductivity and temperature data to salinity. The District's experts testified that the UNESCO calculation reports salinity as a ratio, which is a dimensionless number and has no units. The District uses the UNESCO calculation and performs the conversion in a spreadsheet that it maintains. In some instances, certain brands of data sondes are programmed to perform the calculation and provide the salinity number. The preponderance of the evidence established that use of the practical salinity unit (PSU) is not technically correct. PSU is a misnomer, a pseudo-unit equivalent to a unitless salinity number. The Petitioners' and Intervenors' expert witness, Dr. Anthony Janicki, conceded there is no difference between reporting salinity as unitless or as PSU. And although technically incorrect, he suggested that placing the word "practical" or putting "PSU" in the Proposed Rule would reduce confusion and vagueness. However, since the preponderance of the evidence established that use of PSU is not technically correct, the use of a pseudo-unit would actually cause confusion instead of reduce confusion. The Petitioners and Intervenors also argued that the Proposed Rule is vague because the language does not state that the method of measuring salinity is specific conductivity, or that the equation used to convert specific conductivity and temperature data to salinity is the standard developed by UNESCO. The Petitioners and Intervenors essentially argued that members of the public and those who may be regulated by the Proposed Rule are left to guess about the method or methods used to measure salinity. Because the Proposed Rule identifies and locates by latitude and longitude coordinates the Ft. Myers salinity monitoring station as the location where salinity would be measured for compliance, the Proposed Rule language is not vague. The Proposed Rule is not vague because it does not describe the data sondes, what parameters are measured by the data sondes, and how those parameters are converted to a salinity number. Salinity Monitoring Location and Mean Low Water The Petitioners and Intervenors argued that the Proposed Rule is vague for failing to define the phrase "20% of the total river depth at mean low water," and is arbitrary or capricious for failing to include more than one salinity monitoring station. Total river depth or the water column depth is a standardized measurement that is made from the surface down to the bottom of the river bed. Mean low water is commonly understood in the oceanographic and coastal sciences community as the average of all low tides over the time period defined as the national tidal datum epic. The District's expert witness, Dr. Cassondra Armstrong, testified that mean low water can be determined by using two documents prepared by the National Oceanographic and Atmospheric Administration (NOAA), i.e., the NOAA tide charts and glossary. The District's expert witnesses testified that "20% of the total river depth at mean low water" is the location of the data sonde at the Ft. Myers monitoring station that measures surface salinity. This is also the depth at which Vallisneria is located in the CRE. Since, the Proposed Rule language simply identifies the location of the existing data sonde at the Ft. Myers salinity monitoring station, the language is not vague. The preponderance of the evidence established that the Ft. Myers salinity monitoring station has two salinity data sondes, the one at 20 percent of the total river depth and the other at 80 percent. The data sonde at 20 percent of the total river depth was identified in the Proposed Rule for the following reasons. First, this is the depth where Vallisneria grows and is representative of the salinity exposure for Vallisneria. Second, it guarantees the data sonde is always submerged and able to record data. Third, it has the most comprehensive period of record of monitoring data available. As previously found, Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE. The location of Vallisneria habitat in the upper CRE and its negative response to increased salinity made it an excellent candidate as an ecological indicator for fresh water inflow. Because the preponderance of the evidence established that Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE, the choice of the Ft. Myers monitoring station is not arbitrary or capricious. Water Resource Functions vs. Environmental Values The District's MFL rule specifies that a water body's specific water resource functions addressed by an MFL are defined in the MFL technical support document. See Fla. Admin. Code R. 40E-8.021(31). The Final Technical Document identified the relevant water resource functions of the CRE as fish and wildlife habitats, estuarine resources, water supply, recreation, navigation, and flood control. The Petitioners and Intervenors argued that the environmental values listed in Florida Administrative Code Chapter 62-40, also known as the Water Resource Implementation Rule, were not adequately addressed in the Final Technical Document. A proposed rule challenge is not the proper forum to determine whether a proposed rule is consistent with the Water Resource Implementation Rule. Such a determination is within the exclusive jurisdiction of the Department of Environmental Protection under section 373.114(2), Florida Statutes. Consistency of the District's Proposed Rule with the Water Resource Implementation Rule of the Department of Environmental Protection is not a basis in this proceeding for a finding that the Proposed Rule is an invalid exercise of delegated legislative authority. Other Issues The Petitioners and Intervenors raised other issues during the hearing, although not specifically argued in their proposed final order. Since those issues were identified as disputed issues in the Joint Pre-hearing Stipulation, they are addressed below. 1. Elimination of Single-day Exceedance Criterion During the rulemaking process, Sanibel and SCCF sent the District a letter requesting justification for eliminating the single-day exceedance salinity criterion in the current rule. The District staff evaluated the available Caloosahatchee River MFL compliance record, dating back to when the MFL was adopted in September 2001. The District maintains a historical record of MFL monitoring data and reviewed it to determine if the single-day exceedance salinity criterion was exceeded before the 30-day moving average criterion. The compliance record showed five exceedance events of the single-day salinity criterion have occurred. However, the compliance record also showed that the 30- day moving average salinity criterion had already been exceeded before the five events occurred. In other words, the single-day criterion was never exceeded before the 30-day moving average criterion. Based on this evaluation, the District eliminated the single-day exceedance salinity criterion because it did not provide any additional resource protection. The District's decision was not arbitrary or capricious. 2. Not Using the Latest Model Evaluation of recommended MFL criteria and a recovery strategy for the CRE were greatly aided by integration of a suite of hydrologic and ecological models simulating (1) long-term fresh water inflow associated with varying management options, (2) the resulting salinity in the estuary, and (3) ecological response of indicator species that are sensitive to low fresh water inflows. Five models were specifically utilized, including three models for simulations of fresh water inflows to the CRE, a three-dimensional hydrodynamic salinity model, and a Vallisneria model. The three models simulating fresh water inflows included (1) the South Florida Water Management Model (SFWMM) to simulate fresh water discharges at S-79, which includes regional operations of Lake Okeechobee and incorporates Caloosahatchee River irrigation demands; (2) the C-43 Reservoir Model, which uses the SFWMM-simulated daily S-79 flow as input and simulates the management benefit of the C-43 Reservoir; and (3) the Watershed (WaSh) Model to simulate tidal tributary inflow from the Tidal Caloosahatchee Basin sub-watershed. The Caloosahatchee Hydrodynamic/Salinity Model was based on the Curvilinear Hydrodynamic Three-dimensional Model (CH3D) modeling framework with the functionality of simulating the spatial salinity structure across the entire estuary. The Vallisneria Model took the CH3D modeled salinity as input to simulate Vallisneria growth at critical locations in the estuary. The District did review the more recent Environmental Fluid Dynamic Code (EFDC) model developed for the Caloosahatchee Total Maximum Daily Load (TMDL) and being used by the Department of Environmental Protection. The District's expert witness, Dr. Detong Sun, testified that until 2014, the hydrodynamic part of the EFDC model was not working well. He testified that in 2016, the District still had concerns and suggested the use of the District's continuous monitoring data from seven locations across the CRE rather than grab samples for model calibration. Dr. Sun's opinion was that the EFDC model has improved in recent years, but was still behind the CH3D model in terms of performance. The District's expert witness, Dr. Amanda Kahn, testified that the water quality component of the EFDC model was not appropriate for this re-evaluation because the MFL is about water quantity, not water quality. The water quality component of the EFDC model addresses nutrient loadings, not minimum flows. Dr. Kahn also testified that in setting MFL criteria for the CRE, salinity was not a water quality component. Salinity was used as a water quantity component because it does not change with biological processes and can be a measure of how much fresh water is coming into the system. Based on a preponderance of the evidence, the District's decision not to use the EFDC model was not arbitrary or capricious. 3. Seasonality The Petitioners and Intervenors argued that the District is required to set an MFL that varies by season. For the CRE, the District set MFL criteria that protect the system from low flow that would occur in either the wet or dry season. As previously found, the re-evaluation studies focused on the dry season for two reasons: first, because it is well-established that the upstream migration of salt combined with reduced fresh water inflow alters the health and productivity of estuarine habitats; and second, because the dry seasons are the times when the current MFL criteria are likely to be exceeded or violated. The MFL statute states that "when appropriate, [MFLs] may be calculated to reflect seasonal variations." § 373.042(1)(b), Fla. Stat. The preponderance of the evidence showed that for the CRE, it was not necessary to set an MFL that varied by season. Improper Purpose The Petitioners, Sanibel, Cape Coral, and the Town, did not participate in this proceeding primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of litigation. The Petitioners did not participate in this proceeding for an improper purpose. The Intervenors, Fort Myers, Estero, Bonita Springs, and CCP, did not participate in this proceeding primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of litigation. The Intervenors did not participate in this proceeding for an improper purpose.
Findings Of Fact The Petitioner, Bocilla Waterways, Inc., is a corporate entity formed for the purpose of pursuing the subject project and installing the proposed channel. Randall Craig Noden, secretary- treasurer of that corporation, and a director of it, is a realtor who sells and develops property on Don Pedro Island, in the vicinity of the proposed project. He and other officers and directors of the Petitioner corporation have an interest in property on some, but not all, upland areas adjacent to Bocilla Lagoon, Old Bocilla Pass and Kettle Harbor, the water bodies germane to this proceeding. The Respondent, State of Florida, Department of Environmental Regulation, is a state agency charged with regulating dredge and fill projects in state waters and navigable waters pursuant to Chapters 253 and 403, Florida Statutes, and Rule Chapters 17-3 and 17-4, Florida Administrative Code. The Intervenor, Environmental Confederation of Southwest Florida (ECOSWF), is an incorporated, not-for-profit organization whose membership includes numerous environmentally concerned public interest organizations or associations located throughout southwest Florida. Members of the Intervenor use Old Bocilla Pass, Kettle Harbor, Bocilla Lagoon and Lemon Bay, an adjacent contiguous water body, for boating, swimming, fishing (both recreational and commercial), and collecting shellfish. Some of the membership of the Intervenor live in the immediate area of the proposed project. Project Description The Petitioner submitted a dredge and fill permit application to the Respondent, DER, proposing excavation of an access channel through the uplands of Don Pedro Island and adjacent transitional and submerged lands. The channel would be 100 feet wide, 450 feet long and dredged to a depth of -5.0 feet mean low water, with 2:1 side slopes grading to 3:1 at approximately +0.5 feet NGVD. The channel below mean high water would be 70 feet wide' and 670 feet long to a depth of -5.0 feet mean low water, with 2:1 side slopes. A rip-rap strip five feet wide would be placed in the littoral zone on either side of the channel. As originally proposed, the channel excavation would be performed by dragline and clamshell with spoil placed upon uplands for disposal. The excavation would progress from the west side of the project to the east, with plugs remaining at the eastern terminus of the channel until it stabilizes and the rip- rap is placed along the excavated channel. A turbidity curtain is proposed to be used to maintain water quality above state standards regarding turbidity. The applicant originally proposed to transplant seagrasses, displaced in the excavation process, back into the bottom of the excavated channel. Earthen slopes above mean high water would be vegetated in order to achieve stabilization. Some of these proposals were modified after negotiations with DER staff, such that the seagrass transplanting portion of the project would be accomplished in surrounding areas of the water bottom of Bocilla Lagoon and Kettle Harbor, specifically, bare areas and otherwise degrassed, vegetated flats. The applicant also proposes to install navigation aides in Bocilla Lagoon and Kettle Harbor in order to help maintain boat traffic in the channel, and to facilitate ingress and egress through the proposed channel. Don Pedro Island is a barrier island lying off the coast of Charlotte County, Florida. The only access to the island is by boat or helicopter. Bocilla proposes to excavate the proposed channel in order to, in part, provide better navigational access to Bocilla Lagoon which lies within Don Pedro Island. There is presently a navigational channel in the Bocilla Lagoon through what is called "Old Bocilla Pass," located at the north end of Bocilla Lagoon and communicating with Lemon Bay. Bocilla contends that the channel is somewhat tortuous and subject to shoaling, with concomitant grassbed damage by boat propellers, and that thus, a better navigational access in the form of a shorter, deeper, more direct channel from the southern end of Bocilla Lagoon to Kettle Harbor is required. The project would involve the removal of approximately .18 acres of mangroves (red and black mangroves) and .187 acres of seagrasses. Bocilla has proposed to mitigate the damage involved in the mangrove and seagrass removal by replanting mangroves, on three foot centers, along both sides of the proposed channel, and replanting or transplanting seagrasses in bare areas of Kettle Harbor, near the proposed project. Description of Pertinent State Waters Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass are designated as Class II, navigable waters of the state and are designated for shellfish propagation or harvesting. Shellfish, including clams and oysters, occur in Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass. As demonstrated by Intervenor's witnesses Wade, Cole and Wysocki, shellfish are harvestable and harvested in Bocilla Lagoon and Kettle Harbor at the present time. Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass have also been conditionally approved by DNR for shellfish harvesting. DNR approves or prohibits waters for shellfish harvesting, and as a matter of policy generally prohibits shellfish harvesting in manmade "dead-end" canals. A "conditionally approved" water body, such as those involved herein, is an area approved for shellfish harvesting, but one which is more likely to be affected by pollution events. Thus, they are monitored more closely by DNR. Such events as additional residential development in an area, resulting in more septic tank sewage discharge, on-board toilet discharges from boats or the installation of a water and sewer treatment plant, can result in DNR temporarily or permanently closing a conditionally approved area to shellfish harvesting. Natural phenomenon such as the influx of red tide is also a factor which is considered by DNR in electing to classify a shellfish harvesting area as conditionally approved, and in electing to prohibit shellfish harvesting in an area. It was established through testimony of witnesses Feinstein and Setchfield of DER that long-standing DER policy provides that when DNR conditionally approves waters as being shellfish harvestable, that means they are "approved" for all shellfish harvesting purposes, but simply subjected to closer monitoring and with an increased likelihood of closure due to immediate pollution events. Therefore, the prohibition in Rule 17- 4.28(8)(a), Florida Administrative Code, prohibits issuance of dredge and fill permits in areas approved for shellfish harvesting or "conditionally" approved, since there is no difference in the "shellfish harvestable" nature of the waters until a closure occurs, which may simply occur sooner in conditionally approved waters. Bocilla Lagoon and Kettle Harbor are both naturally- formed water bodies, although some dredging has been allowed to occur in them in the past. They are not manmade, "dead-end" canals. Neither water body has the physical or biological characteristics of a "typical dead-end canal". Both are quite high quality habitats for the natural flora and fauna occurring in the marine environment in that area, and thus the general policy of DNR established by witnesses Cantrell, Fry, Feinstein and Sperling which prohibits shellfish harvesting in manmade, dead-end canals, does not apply to Bocilla Lagoon and Kettle Harbor. The water quality in both bodies of water is good and within DER standards generally. At times however, the water quality in Kettle Harbor suffers from a failure to meet DER dissolved oxygen standards contained in Chapter 17-3, Florida Administrative Code. Indeed, the water quality in Bocilla Lagoon is generally somewhat better than the water quality in Kettle Harbor. Environmental Impacts The project as currently proposed would result in the removal of approximately .18 acres of mangroves and .18 acres of seagrasses. Seagrasses and mangroves are important in providing areas of cover, food, and habitat for various estuarine species. Seagrasses serve to stabilize marine soils resulting in a decrease of suspended solids in contiguous waters with resulting decrease in turbidity in those waters. The loss of seagrasses can result in de- stabilization of the bottom sediment, such that suspended solids or turbidity increases in involved waters, which can result in decreased light penetration to the vegetated bottoms. Decreased light penetration, if of a sufficient degree, can result in the further loss of seagrasses and other bottom flora, causing in turn, increased turbidity and further decreased light penetration, with progressively destructive results to seagrass beds and other marine flora and fauna, with a substantial detrimental effect on the marine biological community in general. Mangroves serve as biological filters, trapping sediments, heavy metals, nutrients and other pollutants, uptaking them through their roots and converting them to usable plant food and thus filtering such harmful elements from state waters and rendering them into environmentally harmless substances. The removal of the mangroves at the proposed channel site will result in a loss of their beneficial effects. These beneficial effects will be absent for a greater period of time than it takes to merely plant replacement mangrove plants, since mature trees will be removed and mangrove seedlings will be replanted in their stead. Maturation of mangroves at this location would take in excess of three years, thus replacement of the beneficial filtering effects of the removed mangroves will take in excess of three years, to which time must be added the time which lapses between the original mangrove removal and the replanting of the seedlings, which would start the maturation period. Bocilla proposes to mitigate the removal of the mangroves by that replanting, as well as to transplant seagrasses removed from the channel site to other nearby areas currently bare of seagrass. Seagrass replanting is not a well-established practice. Compared to mangrove replanting, there is less experience, less information and a lower success ratio historically. Of the hundreds of dredge and fill projects occurring and approved throughout Florida, only three have involved replanting of removed seagrasses. Two of the projects involved the Port of Miami in Dade County and the "New Pass site" in Sarasota County. In both of these cases, seagrass replanting cannot be termed successful. The Port of Miami project resulted in a final survival rate of only twelve per cent of ,the grasses replanted. The New Pass project thus far has resulted in a survival rate of only 39 per cent of the seagrasses replanted, after only nine months. The Petitioner proposes that the replanting be accomplished by Mangrove Systems, Inc. That firm is headed by Robin Lewis, who oversaw the seagrass replanting project at the New Pass area in Sarasota. The location and method of replanting seagrasses at New Pass, as to water depth, type of bottom, type of grass and planting method, was generally similar to that proposed for the Bocilla project. That is, it would be accomplished by "plug planting," of "bald" spots at generally the same latitude and similar water depth. The survival rate at the end of six months at the New Pass project was 73 per cent. The survival rate at the end of nine months was 39 per cent. Mangrove Systems, Inc. and Mr. Lewis acknowledges that it is difficult to attribute the decrease in survival rates and grass shoot densities to any one cause, but that predation and a shift in sediments due to the vagaries of water currents, were probably the chief causes for the decrease in seagrass survival. Mangrove Systems, Inc. and the Petitioner propose a guarantee whereby Mangrove Systems, Inc. would replant more seagrasses, if needed, if a low survival rate occurs, which it defines to mean less than a 70 to 80 per cent survival rate after one or two years. There is no guarantee concerning the survival rate after a second planting, however. It was not established when the survival rate will be measured, in determining whether a 70 to 80 per cent survival is being achieved. In this connection, the central Florida coast where the Bocilla project is proposed, is not as conducive to seagrass growth as other more tropical marine areas, such as in the Florida Keys. In the area of the proposed project, seagrasses do not generally produce a great deal of seed and tend not to grow back very readily, once they are destroyed. Seagrasses in the Florida Keys tend to have, in comparison, much greater seed production and for this and other reasons, tend to reproduce themselves more readily once destroyed. They tend to be more amenable to transplanting in the Florida Keys marine environment. Mangrove Systems, Inc. has conducted a seagrass replanting project in the Florida Keys, however. One-third of the seagrasses planted in that project have not survived after two years. In short, the likelihood of seagrass survival has been insufficiently tested in the geographical area and latitude and in similar soils, water depths and temperatures as those involved in the instant case, such that reasonable assurance of adequate seagrass survival with the replanting project proposed will occur. Hydrographics and Maintenance Dredging The evidence is uncontradicted that the opening of the proposed channel would increase circulation in the southern end of Bocilla Lagoon. Increased circulation tends to have good effects in that it reduces stratification in water bodies. Stratification is a condition which occurs when the deeper waters of a given water body do not interchange with surface waters, but rather stratify or become characterized by layers of differing levels of dissolved oxygen, temperature, pH, etc. Typically, lower levels of a stratified body of water are characterized by low levels of dissolved oxygen. The present water quality of Bocilla Lagoon however, is not characterized by statification in any significant degree. It is very similar in water quality, in terms of dissolved oxygen, temperature, pH and other Chapter 17-3 water criteria, to that water quality of the nearby intra-coastal waterway into which the channel into and through Kettle Harbor would open. The intra-coastal waterway is agreed to be a well- circulated body of water, meeting all current State water quality standards. Accordingly, the opening of the channel and the increased circulation it may cause in the southern end of Bocilla Lagoon would have minimal, positive benefits. The change in circulation and in water current patterns and velocities caused by the opening of the direct, shorter channel from lower Bocilla Lagoon and Kettle Harbor may, negatively affect the present seagrass growth in seagrass beds in Kettle Harbor and Bocilla Lagoon in the vicinity of each end of the proposed channel, due in part to increased current velocities that would result from tidal exchange through the shorter, straight channel which would be opened. The expert witnesses in the area of hydrographics disagreed on the effect of the proposed channel on water circulation in the northern end of Bocilla Lagoon and Old Bocilla Pass, which is the north channel opening into northern Bocilla Lagoon. Witness Sperling for the Department opined that a major reduction in flows through Old Bocilla Pass channel would occur. Witness Tackney for the Petitioner acknowledged there would be some reduction in flow, and witness Olsen opined that a reduction in flow would occur, but there could also be an increase in circulation. Both witnesses Tackney and Olsen, in opining that a flow-through, enhanced circulation and flushing system may result from installing the channel, based that opinion to a significant degree, on their belief on the effects of wind on forcing water through the Pass and Bocilla Lagoon. No wind data or records were adduced however, to show the likely effects of wind on creating the Petitioner's desired "flow-through" system. Witness Sperling disagreed as to the significance of this flow-through effect, but there was no disagreement among the hydrographic experts that reduced flows through Old Bocilla Pass, which all acknowledged can occur to one degree or another, can result in increased sedimentation in Old Bocilla Pass, which can result in turn, in the need for increased maintenance dredging in Bocilla Lagoon and Old Bocilla Pass in the future. Maintenance dredging in Old Bocilla Pass may have to be increased if the proposed channel is constructed. The proposed channel itself will likely have to be periodically maintenance dredged as well. Maintenance dredging can cause environmental problems. Dredging activities result in the loss of marine habitat and the destabilization of marine sediments, with resulting increased turbidity and reduced photic effects, with concomitant detrimental effects on seagrasses and other bottom flora and fauna. Increased turbidity resulting from dredging and destabilization of sediments can directly adversely affect shellfish, including clams and oysters. Dredging impacts and siltation can negatively affect seagrass growth and water quality by increasing turbidity resulting in reduced photosynthesis in seagrass, by smothering the seagrass directly and by silting fauna and vegetation in adjacent productive grassbeds. Persons other than the officers and directors of Bocilla Waterways, Inc. own property and have riparian rights on the Old Bocilla Pass channel. These persons have in the past, and have the right in the future, to use Old Bocilla Pass for navigational purposes and could elect to maintenance dredge Old Bocilla Pass as they have in the past. If the proposed channel is constructed, there is obviously a more direct access and shorter water route between the waters of Bocilla Lagoon and Kettle Harbor. Water quality at times in Kettle Harbor has been worse than that in Bocilla Lagoon, especially in terms of low dissolved oxygen. If poorer water quality exists in Kettle Harbor due to low dissolved oxygen, an influx of red tide or some other cause, the construction of the proposed channel would increase the chance, by the more direct connection and increased flow in the southern end of Bocilla Lagoon, to contaminate the water of Bocilla Lagoon. The Public Interest Public opposition was expressed at the hearing, including that of ECOSWF, the Intervenor, some of whose members include people who live in the area of the proposed channel and use the involved waters. Local fishermen who harvest shellfish and finfish in Bocilla-Lagoon and Kettle Harbor, and use Old Bocilla Pass for navigation between Lemon Bay and Bocilla Lagoon, oppose the project, some of whom are members of the organized Fishermen of Florida, an association of approximately 25,000 members. Residents of Bocilla Lagoon and the immediate area, who habitually navigate Old Bocilla Pass, including local fishermen, have had little trouble navigating Old Bocilla Pass because they are familiar with the channel. Although the Petitioner alleges that the new channel is needed in part for the safety of people living on Bocilla Lagoon to assure quick access to the mainland in case of medical emergencies, the members of the public living on Bocilla Lagoon, (with one exception) and on surrounding areas of the island, do not wish such increased access for medical purposes. The island is presently reached from the mainland by either watercraft or helicopter. Formerly, there was a bridge connecting the island with the mainland which has since been destroyed, and not rebuilt. The residents living on Bocilla Lagoon, either full- time or part-time, buy their homes and choose to live there with knowledge of the present mode of access through Old Bocilla Pass, which is also the means they would achieve access to the mainland in case of medical emergencies or, alternatively, by helicopter transport or by transport over island roads to the ferry landing, with access to the mainland by ferry. The residents, in general, desire to maintain the isolation of life on the island as it presently exists and do not desire enhanced access between the island and the mainland, since part of the charm of having homes and living on the island is its isolation from the more populous mainland. Other than the testimony of Petitioner's witnesses, there was no testimony presented expressing any public need for the proposed channel, as for instance from public officials having knowledge of any medical or public health need for enhanced access to Bocilla Lagoon and the island. The proposed project is contrary to the public interest due to its adverse effects on seagrasses, shellfish, and water quality as delineated above. The adverse effects on seagrasses would result from the dredging itself and the destruction of a portion of the extant seagrass beds, and the resultant likelihood of poor survival rates in the attempted transplanting of seagrass as a replacement for that destroyed by the channel dredging. The proposed project is not in the public interest of those people with riparian rights on Old Bocilla Lagoon and northern Bocilla Lagoon, as there is substantial likelihood the proposed project will reduce flows through Old Bocilla Pass' channel with the resultant increased settling out of sediment and thus increased shoaling of that channel, which would concomitantly increase the need for maintenance dredging in Old Bocilla Lagoon and channel. Additional maintenance dredging and the possible negative effects of such additional dredging on marine, flora and fauna in Bocilla Lagoon and Old Bocilla Pass constitute an additional burden on these riparian owners, the bearing of which is not in their interest. The proposed project is also contrary to the public interest in that the proposed channel is deeper, wider and more direct as an entry into Bocilla Lagoon from Kettle Harbor and Lemon Bay, and would thus allow larger, deeper draft boats to enter Bocilla Lagoon with concomitant increased pollution from oils, greases and possible discharge of onboard sewage, which could have adverse environmental impacts on water quality in Bocilla Lagoon, as well as Kettle Harbor. The use of deeper draft, larger boats with larger propellers and more powerful engines could also result in damage to adjacent grassbeds in the vicinity of either ends of the proposed channel, either through direct propeller contact or through prop wash, when such boats are navigated in areas minimally deep enough to accommodate their draft. Since the installation of the proposed channel would result in a deeper, more readily used access to Bocilla Lagoon by larger boats with the remaining original channel usable also, at least for a time, there is a-substantial likelihood of increased residential development on riparian property around Bocilla Lagoon. This could have the result of reducing water quality in the lagoon, or potentially so, through septic tank leachate, stormwater runoff and other adverse environmental effects, such that the water in the lagoon traditionally approved for shellfish harvesting may be prohibited in the future.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That a Final Order be entered by the Department of Environmental Regulation denying both the variance application and the permit application sought by Bocilla Waterways, Inc.

The Issue Whether Michael Chbat's 2008 application for a Wetland Resource Permit (WRP) to construct a culvert extension across his property in Walton County, Florida, should be approved?
Findings Of Fact La Grange Bayou Estates La Grange Bayou Estates is a residential subdivision in Freeport, Walton County, Florida. The subdivision lies to the north of the shoreline of Choctawhatchee Bay. It can be viewed as divided roughly in half between bayfront lots south of an east-west road that transects the subdivision and lots that are north of the road. The subdivision is platted and the plat is in the public records of Walton County. Filed with the Clerk of the Circuit Court in and for Walton County, Florida, on September 15, 1982, the plat ("the 1982 Plat") shows 29 residential lots in the subdivision as of that date. See Petitioner's Ex. 6. Lots 1 through 16, according to the 1982 Plat, are the bayfront lots, south of a 40-foot wide road designated as a private road in the plat. That road is now known as Alden Lane. Wetlands over which the Department has jurisdiction ("jurisdictional wetlands") comprise much of the southern portion of bayfront lots and the drainage easement. Among the bayfront lots are both Lot 9 which belongs to Mr. Chbat and Lot 8 which belongs to Mr. Sheehey. A 50-foot easement lies between Lot 9 and Lot 8 and is described more fully below. The presence of jurisdictional wetlands on Mr. Chbat's lot over which he hopes to install the culvert extension requires that he obtain a WRP. To the north of Alden Lane are lots numbered by the 1982 Plat as 17 through 29. The lots are served by Alden Lane and, in what is roughly the northeast quadrant of the subdivision, by two other roads. One of the roads is shown on the 1982 Plat as a "40' PRIVATE ROAD." Id. A 2006 aerial photograph introduced into evidence by Chbat designates the road "unnamed." See Chbat Ex. 5. The other is designated as a "graded county road," on the 1982 Plat. By 2006, it had come to be known as Beatrice Point Road. Id. Beatrice Point Road transects a pond that runs roughly 340 feet (excluding about 30 feet of roadway) in a northeasterly direction from Alden Lane to the southern edge of an area north of the subdivision shown on the 1982 Plat to be un-platted. The pond is most likely the result of a "borrow pit" dug in order to obtain fill for the construction of the roads when the subdivision was initially developed. The southern boundary of the pond lies along approximately 140 feet of Alden Lane's northern edge. The pond is across the street from Lots 9, 10 and 11 of the subdivision. The pond is also not far northeast of the 50-foot easement (the "Drainage Easement") between Lots 9 and 8. The Drainage Easement The Drainage Easement is just to the west of Lot 9. It is noted on the 1982 Plat as a "50' EASEMENT (PRIVATE)." Id. The 50-foot wide Drainage Easement runs the length of the western boundary of Lot 9 and the length of the eastern boundary of Lot 8. The northeast corner of the Drainage Easement is approximately 30 feet from the southwest corner of the pond separated from the pond by the roadway of Alden Lane. The eastern boundary of the Drainage Easement is 226.37 feet in length, or if taken to the middle of Alden Lane, 246.3 feet. The western boundary is 206.13 feet long or if taken to the middle of the road, 226.65 feet. The purpose of the Drainage Easement, as is evident from its denomination in this recommended order, is drainage. As Mr. Street definitively put it at hearing, it is "now and always has been intended to drain stormwater to the [B]ay." Tr. Vol. III at 179. Mr. Street's opinion of the function of the Drainage Easement is supported by drawings submitted by Mr. Chbat as part of the WRP application. The drawings show that the Drainage Easement's function is facilitated by three culverts north of the Easement (referred to during the hearing as "pipes") each of which is intended to direct stormwater at its point of discharge toward the Drainage Easement. See Chbat Ex. 1. One of the culverts ("the Drainage Ditch Culvert") serves a drainage ditch that is to the north of the Easement and Alden Lane. According to the drawings, the drainage ditch lies on the other side of the "un-named road" from the pond, that is, to the west of the pond, and is some 40-to-50 feet north of the Drainage Easement. The Drainage Ditch Culvert extends from the ditch to the southern half of Alden Lane from where it appears from the application's drawings that stormwater would be conveyed to the western side of the Drainage Easement along it's border with Lot 8 and on toward the Bay. In fact, it is a functioning culvert that "conveys water from a swale on the side of the road into the [D]rainage [E]asement." Tr. 64. Once in the Drainage Easement, according to the drawings, the water should flow into the Bay out of a "cut," id., that is labeled on the drawings as an "existing trench." See Chbat Ex. 1. The trench, however, has been filled in with sand by tidal activity or sediment deposited by stormwater or both. The trench has not been maintained, and it no longer exists. The other two culverts (the "Pond Culverts") lie east of the Drainage Ditch Culvert. They catch overflow from the pond caused by stormwater and convey it under and through Alden Lane toward the Drainage Easement. The westernmost Pond Culvert (the "Western Pond Culvert") appears to terminate in Alden Lane near its southern edge just north of the Easement. At the time of hearing, however, it was not functioning properly. "[I]t is full of sand and silted up . . .", tr. Vol. I at 58; "[t]he pipe to the west is clogged and it is not functioning." Tr. Vol. I at 64. It is also at an elevation that would keep it from serving drainage purposes in all but the most severe storm events. See Chbat Ex. 9 at 22. The other Pond Culvert, (the "Eastern Pond Culvert") terminates in the northwest corner of Lot 9 at the border between Lot 9 and the Drainage Easement about 10 feet southeast of the terminus of the Western Pond Culvert. The Eastern Pond Culvert is the culvert with which the Amended Permit is concerned, that is, it is the culvert to be extended by the permit. Calling it a "pipe," Mr. Street offered the following about the assistance the Eastern Pond Culvert offers in conveying stormwater into the Drainage Easement and down to the Bay: There is currently a pipe that discharges into that easement. There . . . was an attempt to place the water from the . . . pond into the easement. And the natural flow of water on this entire property from the road to the [B]ay is north to south. At some point, at least 2004, that drainage easement contained a conveyance at its southern end that would safely discharge stormwater to the [B]ay. Tr. Vol. III at 179-80. Petitioner Sheehey and Lot 8 Thomas Sheehey is the owner of Lot 8, where he has a residence in which he makes his home. He has lived in the residence approximately five years. During that time, Mr. Sheehey has fished in the Bay and enjoyed the use of his kayak and his waverunner on the Bay. He also enjoys "sitting down having a cup of coffee and looking at it," tr. vol. III at 151, as well as watching his neighbors fish. The recreational uses to which he puts the Bay is the reason he chose to purchase a bayfront lot in La Grange Bayou Estates. Over the period of time that he has resided on Lot 8, Mr. Sheehey has observed the effects of rain events on his lot and well as lots close to Lot 8. He has also taken pictures of his property and the near-by lots. Among the photographs were four taken after rain events or "after a wet period," tr. vol. III at 88, at some point in the last four years. The four photos were introduced as a composite exhibit, Petitioner's Ex. 2, with each photograph marked as 2A, 2B, 2C or 2D. Mr. Sheehey could not specify when the pictures were taken in the past four years other than that if a picture had a certain dock in it, then it was taken after January of 2009. Petitioner's Ex. 2A was taken from Mr. Sheehey's lot looking toward the Bay. It shows an area of the lot under water separated from the Bay by a ridge. Petitioner's Ex. 2B is a picture taken from Lot 13 looking west across Lots 12, 11, 10, 9 "down through 8." Tr. Vol. III at 86. Much of what is photographed is among trees and vegetation emerging from water standing above the surface of the soil. Petitioner's Ex. 2C is a picture taken from Alden Lane looking south across Mr. Chbat's property. It shows a wide swath of water that extends from the road across most of the property to the Bay. The water is either in a swale or constitutes overflow outside the swale. The most recent of the four is Petitioner's Ex. 2D, which shows the dock referred to by Mr. Sheehey that was built in early 2009. It is a picture taken from Lot number 13 toward the west through Lots 12, 11, 10, 9. Like the others, it shows vegetation standing in water to the north of the Bay. Taken together, the four pictures in Petitioner's Exhibit 2 demonstrate that significant portions of the lots depicted are under water following sufficient amounts of recent rain. The four photographs that comprise Petitioner's Exhibit 2 are not the only photos taken by Mr. Sheehey that were introduced into evidence. Three other photographs of Mr. Sheehey's, Petitioner's Exhibits 7A, 7B and 7C, were admitted following testimony about them from a long-time observer of the flow of water from Alden Lane to the Bay. A Long-time Observer Thomas Eugene Cummins had lived in La Grange Estates "[t]wo months shy of 20 years," tr. vol. III at 7, at the time of his testimony. His house was the fourth to be constructed in the subdivision. Over the two decades of his residence, the pond between Alden Lane and the property north of the subdivision has been in existence. Consistent with the drawings submitted to DEP as part of the application, when asked where the pond overflows today, Mr. Cummins answered "it drains under Alden Lane on to Mr. Chbat's lot." Tr. Vol. III at 8. Asked by Mr. Chesser at hearing, "When the water comes out of the pond, is it possible to know where it spreads?"1/ Mr. Cummins testified: On really heavy rains, I have watched the normal color of the pond change from its dark blackish gray color into the reddish color that the clay has washed down into it, flow under Alden Lane and on to Mr. Chbat's lot, and then proceed west through the wetland on lots eight, seven, six, and my five, and turn reddish color even in my lot. Tr. Vol. III at 9-10. Mr. Cummins knew the source of the "red color" of the stormwater: red clay introduced to La Grange Estates by the County half a decade earlier. Mr. Cummins testified: Beatrice Point Road, which is the road that runs over the pond, about five years ago the county did some repair on the road and actually put red clay in certain spots to even it out. Tr. Vol. III at 9. Prior to the county's work on the road referred-to by Mr. Cummins, there had been no red clay in the neighborhood. Alden Way, for example, has no red clay. It is a road composed of shell. The only red clay in the subdivision is that which is on Beatrice Point Road. The water that runs onto Mr. Cummins' lot following a heavy rain rises to as much as 12 inches.2/ The water rises as high as it does because it is held back by a naturally-occurring land formation between the Bay and Mr. Cummins property. This geo-formation was referred-to at hearing as the ridge line or the ridge. The Ridge The Ridge was described by Mr. Cummins as a vegetated mass of earth that most of the time, even in heavy rains, sits above the water that collects on the bayfront lots of La Grange Estates. The Ridge prevents a substantial amount of stormwater runoff from entering the Bay from the wetlands on the southern portion of the subdivision's bayfront lots. For that reason, the ridge is called "our upland,3/" tr. vol. III at 13, according to Mr. Cummins. Between Lot 9 and Lot 5, the ridge varies in width "anywhere between 10 feet . . . up toward Mr. Chbat's lot, down to [Mr. Cummins'] lot where its around 30 or 40 feet [wide.]" Id. (It may extend, in fact, across all of the bayfront lots.) The ridge meanders not far from the shoreline. Id. In some places it is as narrow as five feet. The height of the ridge varies as well from as low as one foot to as high as two and half feet. Mr. Street also testified about the Ridge, referring to it in his testimony as a "ridge line": Now, there is a ridge line, and there's been a lot of testimony about this ridge line, that it exists across all of the lots. My testimony was, essentially, related to the review that I did, which was primarily associated with lots eight and nine, and the drainage easement between them. And from what I can tell, the elevation of that ridge line is give or take three. Elevation three, not a height of three. An elevation of three. It could be lower, and perhaps, is higher. And its subject to the vagaries of a number of factors, flow of stormwater, wave action, tidal influence, and the like. And these accretions and depositions of sand over time change that ridge line. And sometimes, it opens up. And sometimes it may not have a natural opening, depending on where you are along that entire stretch of beach. * * * [T]o the extent there is an opening in that ridge line, water will flow naturally to the bay. Tr. Vol. III at 180-181. An "east west flow of water," tr. vol. III at 181, along the bayfront lots, that is, a flow of water either in an easterly direction or a westerly one is contrary to the flow from Alden Lane north of the lots to the Bay south of the lots. Whether flowing east or west, the water in the southern portions of the bayfront lots is "controlled by the ridge line." Id. In other words, stormwater that flows from north to south across the bayfront lots, including Mr. Chbat's and the Drainage Easement, is going to collect and begin to flow from east to west or west to east at some point north of the Ridge before it drains into the Bay. The only exception to east-west flow, as made clear by Mr. Street, is when and if there is an opening in the Ridge that allows the water otherwise held back by the Ridge to flow southward into the Bay. The east-west flow of the water along the Ridge was described at hearing as "unnatural." Id. In fact, it is not un-natural. The Ridge is the cause of the east-west flow and, as Mr. Street testified, the Ridge is the result of natural processes such as tidal influence, wave action, accretion and deposition of sand.4/ The Ridge is shown in Petitioner's Exhibit 7A,5/ another photograph taken by Mr. Sheehey. The ridge as shown in the picture is well vegetated and above water to its north and higher than the Bay to its south. It is quite clear that if there is no opening in the ridge to the Bay, stormwater north of the ridge is forced to flow in east-west directions and is prevented from flowing into the Bay. Petitioners' Exhibit 7B is a photograph of the southern terminus of a swale (see paragraphs 40 - 49, below) on Mr. Chbat's property. It shows the swale cut through the Ridge. Water, however, does not appear to be running from the end of the swale into the bay. It appears that the end of the swale is a few feet from the Bay separated by a narrow sandy area on the shore. Nonetheless, the photograph shows that there is potential for stormwater to flow from the swale when the swale has more water in it. Petitioner's Exhibit 7C is a picture of the pond6/ across the street from Mr. Chbat's Lot 9. Mr. Chbat and Lot 9 Michael Chbat is the owner of Lot 9. He purchased the lot "[t]o build a house on it." Tr. Vol. I at 22. Because he has family close by (in Fort Walton Beach), Mr. Chbat expects to use a house built on the lot for weekend visits. His ultimate aspiration is to live in a house on Lot 9 after he retires from his position as a construction engineer with the City of Tallahassee. At hearing, Mr. Chbat described Lot 9 on the day he bought it: "the lot was overgrown. It drained from north to south. It had water standing on it. And it had a pipe [the Eastern Pond Culvert] on the northwest corner discharging." Tr. Vol. I at 23. He also described the state of the lot at the time of hearing. The Eastern Pond Culvert on the northwest corner was still there. The lot had been cleared to some extent to rid it of invasive species. Overgrown vegetation was trimmed or cleared to make room for a driveway permitted by the Department and "a parking pad in the front area of it, as well as an access pad in the uplands." Id. A dock had also been constructed from the property into the Bay. The most significant difference between the lot at the time of purchase and the lot at the time of hearing for purposes of this proceeding is that the lot now has a swale (the Swale) that runs from the point of discharge of the Eastern Pond Culvert "all of the way to the bay area." Id. The Swale The Swale was put in sometime after March 20, 2007, as the result of a Settlement Agreement fully executed on that date "By and Between Michael Chbat and Thomas L. Sheehey." Petitioner's Ex. 10. The Settlement Agreement followed events that commenced in 2004 when Mr. Chbat filed an application (the "2004 Application") with DEP for a WRP primarily to construct a house and a boardwalk leading from the house on Lot 9 to a dock in the Bay. The 2004 Application also proposed the extension of the Eastern Pond Culvert with a "pipe" along the western boundary of Chbat's property in a manner substantially similar to the culvert extension allowed by the Amended Permit that is the subject of this proceeding. On October 28, 2005, DEP proposed that the 2004 Application be granted. The permit (the "Proposed Original Permit") was assigned No. 66-0235320-001-DF. See Petitioner's Ex. 10, at 2. The Proposed Original Permit was challenged by Mr. Sheehey when he "filed a Petition for Administrative Hearing contesting certain action authorized under the [Proposed Original] Permit . . . specifically the relocation of a drainage pipe . . . ." Petitioner's Ex. 10, at 2. After referral of the petition to DOAH, Mr. Chbat and Mr. Sheehey wrote in the Settlement Agreement that they had "determined that it is in their best interests to settle this matter amicably pursuant to the terms hereafter". Id. Among the terms is that Chbat would file an Amended Application. See id. The agreed-to amendment to the 2004 Application was attached to the Settlement Agreement as Exhibit "A," a drawing of a "Drainage Swale Plan," produced by Genesis Group for Mr. Chbat. The drawing depicts a swale that runs from the discharge point of the Eastern Pond Culvert nearly the full length of the western boundary of Lot 9 to the Bay. See Exhibit "A" to Petitioner's Ex. 10. The Swale was designed to take the place of the 2004 Application's proposal for a "pipe"7/ attached to the point of the discharge from the Eastern Pond Culvert. The Settlement Agreement received the support of DEP because the Department believed that a swale would assist in improving the quality of the stormwater discharged to the Bay over the untreated discharge from the end of the "pipe." Pursuant to the terms of the Settlement Agreement the 2004 Application was amended. The Department amended the Proposed Original Permit accordingly and final agency action was taken with the issuance of a permit to Mr. Chbat (the "Final Original Permit") found in DEP Permit File No. 66-0235320-001- DF. Installation of the Swale The Swale was installed, but it did not work as intended. The result of the Swale's installation was more water on the lot rather than less. Mr. Chbat described the after-effects of the Swale: "it started bringing more water to the lot . . .". Tr. Vol. I at 31. The increased amount of water is the result of several factors, one of which is tidal influence: the tide from the Bay pushes water into the Swale. "[A]bout halfway on the swale . . . that water from the bay was meeting the water from the pipe . . .". Id. The water from the Bay tide and the stormwater conveyed by the Swale would meet at "about the middle of the span of the swale." Id. The result was "a lot more water," id., on the lot. Mr. Thomason confirmed Mr. Chbat's assessment that the reason the Swale did not function as effectively as necessary is tidal flow onto Lot 9 from the Bay particularly from high winds. But tidal flow onto Lot 9 and the interruption in the discharge of stormwater through the Swale are not the only problems. There is also a maintenance factor that accompanies tidal flow: sand deposition. Mr. Thomason elaborated: "[D]uring storm events or [just normal] wave action in the bay, sand is brought back up on to . . . the sandy area at the end of [Lot 9] next to the [Bay.]"8/ Tr. Vol. I at 62. The influx of sand onto Lot 9 is not just a problem for adequate functioning of the Swale. The Drainage Easement has "the same problem." Id. Both the Swale and the Drainage Easement are plagued by deposition of sand pushed landward by normal tidal influences and storm events. Maintenance of the Swale and the Drainage Easement, therefore, would assist the drainage of stormwater into the Bay. The tidal influence and maintenance issues that Mr. Chbat encountered with the Swale led him to apply for a different and new permit. That application was filed in 2008. The 2008 Application Mr. Chbat filed a "Joint Application for Works in the Waters of Florida" with DEP on August 1, 2008 (the "2008 Application"). See Chbat Exhibit 1. The work to be approved was similar to the work originally proposed in the 2004 Application in that both applications proposed installation of a "pipe" to be fixed to the discharge point of the Eastern Pond Culvert that would run along the western boundary of Lot 9 toward the Bay. A description of the work is contained in Section 10 of the 2008 Application: "Extension of an existing stormwater pipe within a private lot approximately 150 feet. The slope for the proposed pipe extension will be at minimum so that stormwater will be treated further, and minimizing erosion." Chbat Ex. 1 at 3. After the filing of the 2008 Application, Mr. Chbat learned that Mr. Sheehey objected to the newest Chbat proposal because he believed 150 feet is not lengthy enough to clear the Ridge. See Chbat Exhibit 2. In order to cure the objection, Mr. Chbat proposed a modification to the 2008 Application. He attached a "sealed and signed drawing," id., to a letter dated September 18, 2008, that he submitted to DEP. The drawing shows the extension to be 177 feet, 27 feet more than initially proposed by the 2008 Application. The additional 27 feet was intended to ensure that the discharge would be directly into the Bay in order to "eliminate any possible run-off impact to adjacent properties." Id. The modification was accepted by DEP." See exhibit number 19/ attached to the Amended Permit, Chbat Exhibit 4. There was conflicting evidence in the proceeding on whether the outfall from a culvert extension of 177 feet will be bayward of the Ridge. The issue was put to rest by Mr. Street’s testimony in rebuttal at the hearing. See Tr. Vol. III at 194 and 203-4. His testimony establishes that the point of discharge at the end of the culvert extension will clear the Ridge so that the discharge will be directly into the Bay. The Mound The culvert extension is designed at an elevation and with cover (presumably sod). The extension runs through jurisdictional wetlands and segments them. It does not, however, isolate any portion of the wetlands. The wetlands on Mr. Chbat's property and those to the immediate east and west of it, therefore, will retain their status as jurisdictional wetlands should the extension be installed. With its sod cover, the culvert extension will be a mini-berm (or a "mound" as Mr. Street called it) at an elevation of 17 to 18 inches above grade. Water that pools to its west will no longer be able to flow eastward of the mound (except rarely under the most extreme weather events.) Conversely, water that collects to its east will no longer be able to flow westward of the extension. It would have to be a severe storm event for water to rise above the mound. Mr. Chbat has never seen water rise to 18 inches above grade and Mr. Cummins testified the highest water ever gets on his property is roughly 12 inches. The Department approved the 2008 Application as modified to lengthen the extension to 177 feet and issued the Amended Permit. But an incorrect and critical assumption was made during review of the application that related to the mound. Review of the 2008 Application During his review of the application, Mr. Street, as DEP's stormwater engineer, assumed from the drawings that the Drainage Easement is functional.10/ The assumption was expressed in Mr. Street's testimony in the Department's case-in-chief: Q [D]id you determine whether the pipe, as it would be mounded . . . [the culvert extension covered in sod] . . . would create problems for storm water flow? A I looked at that. There were two conclusions that I drew. One was that the mound would create a higher water elevation on the Chbat property east of the mound, but would not create standing water west of the mound extending into the [Drainage E]asment . . . . Which on the drawings that I reviewed showed an existing trench at the south end of that easement. And it was my opinion that any water that fell west of the mound would exit through the easement. Tr. Vol. II at 92 (emphasis added.) Mr. Street's assumption that water would not pool to the west of the mound in the Drainage Easement and toward Mr. Sheehey's property was contradicted by Mr. Sheehey's stormwater engineer, Mr. Porterfield. THe Porterfield Testimony and Support for It at Hearing The testimony at hearing of Mr. Porterfield, who conducted a site visit, established the opposite of what Mr. Street assumed. The volume of stormwater runoff that pools east of the mound, that is, water on Lot 9, will not be as great as the volume as the water that pools west of the mound. Water that would have flowed onto Lot 9 from the Eastern Pond Culvert will flow directly to the Bay via the culvert extension. The extension will also protect the Drainage Easement and Lot 8 from water that would have flowed from the Eastern Pond Culvert onto that property. But there is a significant difference between stormwater to the west of the extension and to the east. To the extension's west, the Drainage Easement and Lot 8 will have to contend with stormwater from the Drainage Ditch Culvert, the culvert north of Alden Lane that does not convey stormwater from the pond but that like the Pond Culverts has a discharge point directed at the Drainage Easement. How often and to what extent pooling of stormwater will occur west of the mound due to its presence is difficult to determine on the state of this record.11/ No studies or analyses of the likelihood and severity of storm events and the volumes of stormwater runoff that would be produced by them were conducted by any of the stormwater engineers in the case nor were any such analyses done with regard to pooling caused by the presence of the covered culvert extension. The testimony of Mr. Porterfield, however, and other evidence, demonstrates that that additional collection of water west of the mound caused by the mound will occur following heavy rain. Mr. Street was present in the hearing room throughout the entire hearing, including during the presentation of Mr. Sheehey's case. As Mr. Street candidly testified on rebuttal after he had heard all the evidence: I would also maintain that the drainage easement which has signs of a historical usage as a drainage easement with a trench, in fact, that conveys water safely to the bay, that should be re-established and maintained. That’s what it’s there for.” Tr. Vol III at 181 (emphasis added.) Thus, it became clear to Mr. Street after listening to all the evidence in the case that the Drainage Easement has not been properly maintained. The trench that was expected to carry stormwater toward the Bay no longer exists. In short, the testimony of Mr. Street, for all his many strengths as a witness, falls short of supporting the position of the Department and Mr. Chbat. Having never visited the site,12/ he approved the project on the basis of drawings that do not conform to the on-site physical reality. When presented with the evidence at hearing that the Drainage Easement is not functioning, he championed re-establishment and maintenance of the Drainage Easement. Mr. Chbat placed part of the Swale's functionality problem on the tide pushing stormwater northward but his case also recognized the maintenance problem caused by deposition of sand that besets the Swale. Mr. Thomason, moreover, recognized that the Drainage Easement has the same maintenance issue. Mr. Chbat's stormwater engineer testified During storm events or just normal wave action in the bay, sand is brought back up on to. . . the sandy area at the end of [Chbat's] lot next to the water. And so that . . . tends to inhibit the natural flow down the swale . . . we have the same problem on the drainage easement . . . where sand builds up in that discharge. Tr. Vol. I at 62 (emphasis added). From this record, it is clear that neither the Swale nor the Drainage Easement functions properly. Their functional status, moreover, is due in significant part to lack of maintenance. It may be that maintenance ultimately will not solve the problem; maintenance efforts to keep the Swale and Drainage Easement clear of the sand deposited by tidal activity may require too much effort for them to be reasonably required. But that evidence was not produced. Indeed, the record was silent as to any maintenance efforts with regard to the Swale by Mr. Chbat or with regard to the Drainage Easement by the owner of the easement. The record is also silent as to whether DEP voiced any concern about the maintenance issues that beset the Swale. It is clear that concern was not raised by the Department in regard to the Drainage Easement until the rebuttal phase of the hearing, since the assumption was made that the easement was properly maintained. Whatever communication may have occurred with regard to maintenance issues among the parties, the Department issued the Amended Permit.13/ The Permit/Authorization Number for the Amended Permit is 66-235320-002-DF.14/ Issued December 19, 2008, the Amended Permit has an expiration date of December 19, 2013. The expiration date coincides with the construction phase of five years on the face of the Amended Permit. See Chbat Ex. 4. Mr. Sheehey Challenges the Amended Permit On January 6, 2009, Mr. Sheehey, pro se, filed with DEP a petition (the "Petition") seeking a formal administrative hearing with regard to "Amended Wetland Resource Permit 66- 00235320-002-DF." Although the Petition makes reference to the Amended Permit, it seeks in the first instance enforcement of the Settlement Agreement that relates to the Final Original Permit. The Petition states: "Petitioner believes that the Florida Department of Environmental Protection has jurisdiction over this matter and should enforce the March 20, 2007 Settlement Agreement which requires that Permittee act in conformance with Exhibit 'A' of the Agreement [the drawing of the Swale]." In the event that DEP declined to enforce the Settlement Agreement, the Petition sets out disputed issues of material fact that relate to issuance of the Amended Permit. The Petition was referred to DOAH on February 19, 2009. One week before the final hearing, the Department filed the motion in limine that is discussed in the Preliminary Statement of this Recommended Order. The motion was granted to the extent that it sought to preclude Sheehey from introducing evidence that supported enforcement of the Settlement Agreement since the 2008 Application, which, while bearing similarity to the 2004 Application, is nonetheless an independent application that should be approved or denied on its own merits without regard to the 2004 Application, the Proposed Original Permit, the Settlement Agreement or the Final Original Permit. The case proceeded to hearing on the remaining issues raised by the Petition: 1) whether Sheehey has standing to contest approval of the 2008 Application; 2) whether Chbat gave the notice required by Section 373.413, Florida Statutes, and 3) whether Chbat's application meets the criteria in statutes and rules for issuance of the Amended Permit. Standing The findings of fact relevant to Mr. Sheehey's standing are found in paragraph 9, above. Notice Notice of the 2008 Application was published in The Defuniak Springs Herald-Breeze, a newspaper published in Defuniak Springs, Walton County, Florida. The notice was published on October 23, 2008. The evidence presented by Mr. Sheehey concerning lack of legal notice consisted of testimony by Mr. Sheehey at hearing in response to questions from his counsel. See Tr. Vol. III at 134. The testimony does not establish that Mr. Sheehey was a person who had filed a written request for notification of any pending application affecting his particular area. The testimony of Mr. Sheehey, moreover, establishes that he was given oral notice of the application by Mr. O'Donnell within four days of its filing. WRP Permitting Criteria To obtain a WRP, an applicant must satisfy the criteria in Florida Administrative Code Chapter 62-312 and Section 373.414, Florida Statutes. These criteria govern a range of topics including water quality. Water Quality15/ Florida Administrative Code Rule 62-312.080 provides that no permit shall be issued unless the Department has been supplied with reasonable assurances that the proposed work will not violate water quality standards. Water that enters the pond spends some amount of time in the pond (residence time) before flowing out. During residence time, solids drop out of the water so that the quality of the stormwater that flows out of the pond is reasonably expected to be better than the quality of the stormwater runoff when it entered the pond. Vegetation surrounding the pond, furthermore, enhances the quality of the water in the pond, whether the water’s source is runoff or rain falling directly into the pond. The water that flows out of the pond north of Alden Lane is “existing discharge.” Tr. Vol. I at 65. It generally made its way to the Bay prior to the Swale. Some of it makes its way to the Bay via the Swale now; some of it outside the Swale as overflow. The culvert extension will convey that discharge to the Bay if the extension is installed. The quality of the water is not significantly less when it discharges to the Bay via the Swale or otherwise from the Chbat property than when it would enter the culvert extension should it be installed. It is true that the Swale would have provided filtration and additional treatment to the discharge from the Eastern Pond Culvert as does the Chbat property in general. But that does not mean that the quality of the culvert’s discharge is a concern. The Swale may have been an option preferable to the extension of the culvert as far as water quality goes but all parties agree that the Swale has failed as a conveyance (albeit Mr. Sheehey maintains that the Swale would work with proper maintenance.) That there is a discharge method that improves the quality of the discharge, such as a swale, does not mean that the discharge to the Bay via the culvert extension is of insufficient quality. None of the parties tested the quality of the discharge from the Eastern Pond Culvert. The Department, nonetheless, offered evidence with regard to its quality. The Department concluded that the quality of the pond and its discharge were not of concern. Had the pond been contaminated to an extent that would have given rise to concerns, moreover, the Swale or the culvert extension as a means of conveying the discharge to the Bay would not have made a “discernible difference.” Tr. Vol. II at 80. The Department provided evidence of assumptions made with regard to the quality of the water that led the Department to conclude that testing of the discharge was unnecessary. Mr. O’Donnell, the Department’s expert in the application of state rules and statutes in wetland resource permitting, detailed the assumptions at hearing: My assumption was that that pond was dug some time in the past as a way to provide fill for roads. That it was never any part of . . . [a] stormwater treatment system. And that it conveyed upstream water through the pond and then on down into Choctawhatchee Bay. It was strictly a [borrow pit and a conveyance pond.] It was never permitted as a treatment system in any way that I was aware of in my diligence [in determining whether the extension should be permitted.] Tr. Vol. II at 79. Once Mr. O’Donnell’s testimony entered the record at the behest of Mr. Chbat, the burden shifted to Mr. Sheehey to prove that the applicant had not provided reasonable assurance of water quality. Mr. Sheehey did not offer evidence of any testing of the discharge. Nor did he offer testimony that rebutted Mr. O’Donnell’s opinion. In fact, the testimony of Mr. Wilkinson (Mr.Sheehey's witness) supported Mr. O'Donnell's opinion with regard to water quality. See Tr. Vol. III at 112. In sum, the Department made assumptions that are found to be reasonable based on Mr. O’Donnell’s expertise and experience. Those assumptions were not shown to be unreasonable by Mr. Sheehey. The Department’s conclusions about water quality flow directly from Mr. O’Donnell’s reasonable assumptions. Reasonable assurances have been provided that the project will not violate water quality standards. Public Interest Test Choctawhatchee Bay is not designated as an “outstanding Florida water.” The test that Mr. Chbat must meet therefore is whether the activity proposed by the permit application is “not contrary to the public interest.” § 373.414, Fla. Stat. In making that determination, the Department is directed by the statute to consider and balance seven criteria. See § 373.414(a) 1-7, Fla. Stat. Of the seven, three are at issue once water quality is determined to be of no concern. Two of the three, “[w]hether the activity will be of a temporary or permanent nature,” Section 373.414(1)(a)5., Florida Statutes, and “[t]he current condition and relative value of functions being performed by areas affected by the proposed activity,” Section 373.414(1)(a)7., Florida Statutes, do not require in-depth consideration. With regard to the nature of the project time-wise, the evidence establishes that the culvert extension is intended to be permanent. With regard to current condition, the area affected by the proposed activity is a residential lot, a substantial portion of which is under water following heavy rain. To facilitate the conveyance of stormwater, the lot is served by the Swale. The Swale is not functioning optimally because of lack of maintenance and because of the Ridge. With regard to relative value from the standpoint of water quality, the function being performed by the lot and the Swale is little, at least as established by this record. While it is certainly true that the lot with or without the Swale will filtrate and otherwise treat stormwater runoff from the pond, the difference in the quality of the stormwater conveyed by the culvert extension from that which would enter the Bay without the extension is not significant. See the discussion above of Mr. O’Donnell’s accepted opinions. Of the seven statutory criteria to be weighed and balanced by the Department, the one that is central to this case is found in subparagraph 1., of subsection (1)(a): “[w]hether the [culvert extension] will adversely affect . . . the property of others.” The “property of others” in this case is the property of Mr. Sheehey. The Project’s Effect on the Property of Mr. Sheehey. For the reasons discussed in paragraphs 63-70, above, Mr. Chbat has failed to provide reasonable assurances that the project will not have a detrimental effect on the property of Mr. Sheehey. The extent of the detrimental effect to Mr. Sheehey's property is difficult to determine from this record but it is highly likely based on all the evidence of record that there will be a detrimental effect: additional flooding in heavy rain events.
Recommendation Based on the foregoing, it is recommended that the Department of Environmental Protection deny17/ the Amended Permit for the failure of Mr. Chbat to provide reasonable assurances that the project will not adversely affect Mr. Sheehey's property.

Findings Of Fact THE PARTIES The Respondent is the successor agency to the Florida Department of Environmental Regulation and has permitting authority over the subject project pursuant to Chapter 403, Florida Statutes. The Respondent's file number for this matter is 311765419. Petitioner, Alden Pond, Inc., is a subsidiary of First Union National Bank of Florida and is the successor in interest to Orchid Island Associates. John C. Kurtz is the designated property manager for this project and appeared at the formal hearing as Alden Pond's authorized agent. THE PROPERTY AND THE VICINITY Petitioner has record title to all of Government Lot 9 in Section 15, Township 31 South, Range 39 East, less the Jungle Trail Road right of way, and all of Government Lots 2, 3, 6, and 7, Section 22, Township 31 South, Range 39 East, less the road right of way for State Road 510. Petitioner does not own land below the mean high water line of the Indian River, which forms the western boundary of the property. Much of the property, approximately the northern half, abuts a part of the Indian River that has been leased by the State of Florida to the United States Fish and Wildlife Service as part of the Pelican Island National Wildlife Refuge. The Pelican Island National Wildlife Refuge was the first national wildlife refuge established in the United States and has been declared to be a water of international importance. Upland of the proposed project is a golf course and residential development. The Indian River at the project site is within the Indian River Aquatic Preserve, which is classified as Class II Outstanding Florida Waters. The Indian River in the vicinity of the project is part of the Intercoastal Waterway system, is navigable by large vessels, and is an important travel corridor for manatees. The Indian River in the vicinity of the project is a healthy estuarine system. Minor deviations from Respondent's dissolved oxygen standards have been recorded. These minor deviations are typical and represent natural conditions for this type of system. Water quality sampling from March 1994 yielded no samples in which deviations from Respondent's dissolved oxygen standards were observed. THE ORIGINAL PROJECT On February 21, 1990, Orchid Island Associates submitted to the Respondent an application for a wetland resource permit to construct a boat basin and canal on its property adjacent to the Indian River. The artificial waterway that Petitioner proposes to construct on its property will, for ease of reference, also be referred to as a canal. Petitioner proposes to dredge from the north terminus of the canal to the Intercoastal Waterway a channel, which will be referred to as the hydrological channel. Petitioner proposes to dredge from the south terminus of the canal to the Intercoastal Waterway a channel, which will be referred to as the access channel. The original project involved, among other features, a canal approximately 6,400 feet long, the dredging of the hydrological channel and the access channel, the construction of 44 docks to be located along the eastern side of the canal, and the dredging of an area adjacent to the canal for a 58 slip marina. The width of the canal was to range between 100 and 200 feet. The original project required the filling of 4.72 acres of wetlands and the dredging of 8.81 acres of wetlands for a direct impact on 13.53 acres of wetlands. On January 15, 1991, Respondent issued a preliminary evaluation letter pertaining to the initial application that contained the following conclusion: "the project cannot be recommended for approval." On September 12, 1991, Respondent issued a Notice of Permit Denial dated September 12, 1991, which stated that the application would be denied. This denial letter did not suggest any revisions that would make the project permittable and represented a strong position by the Respondent that the project as originally proposed should be denied. The September 12, 1991, Notice of Denial correctly described the project site and the initial proposal as follows: . . . The proposed project is located north of and adjacent to County Road 510, north and east of Wabasso Bridge and adjacent to the eastern shore of the Indian River. The Indian River at the project site is within the Indian River Aquatic Preserve, which is classified as Class II, Outstanding Florida Waters. The Pelican Island National Wildlife Refuge, also an aquatic preserve and an Outstanding Florida Water, is immediately west of the project site. Historically, the site of the marina and its associated upland development consisted of a wetland adjacent to the Indian River and a large citrus grove. Subsequently, the wetland was surrounded by a dike and impounded for mosquito control purposes. At some point in the past, a borrow pit 1/ was excavated within the landward (eastern) edge of the impounded wetland. Most of the citrus grove has been converted to a residential community associated with a golf course. * * * The proposed project included excavation of a 6,400 linear ft. canal along the upland/wetland edge between the impoundment and the adjacent upland, dredging the existing borrow pit to a depth of -8 ft. NGVD to create a boat basin that will connect it to the excavated canal, construction of 58 boat slips within the excavated boat basin, excavation of two flushing channels through a portion of the impoundment dike and wetlands within the impoundment to connect the excavated channel to the Indian River and a natural lake within the impoundment, excavation of a 700 ft. long access channel to connect the excavated canal to the Intercoastal Waterway through the seagrass beds along the southern boundary of the project site, filling of 4.72 ac. of wetlands at three locations within the impoundment to create uplands, and construction of a boardwalk along the southern edge of the excavated canal through the wetlands in the impoundment to provide access to the marina basin. To mitigate for the loss of wetlands, the applicant proposes to enhance 68 ac. of wetlands within the mosquito impoundment by returning the impoundment berm to grade and implementing a rotary ditching project and open marsh mosquito management to improve the hydrology of the wetlands in the impoundment, planting high marsh species, and donating the enhanced wetlands to the State of Florida for incorporation into the Pelican Island National Wildlife Refuge through a lease to the United States Fish and Wildlife Service. The September 12, 1991, Notice of Denial provided, in pertinent part, the following reasons for the denial of the project: The Department hereby denies the permit for the following reasons: Water quality data for the Indian River adjacent to the project site indicates that the dissolved oxygen (D.O.) standard is not currently being met. The proposed 8 ft. deep canal and marina basin to the Indian River would be expected to result in introduction of additional low D.O. waters into a system which already does not meet the D.O. standard, thereby resulting in further degradation of the water quality in the Indian River. In addition to the D.O. problem, the project would result in water quality degradation due to the pollutant loading of marina related pollutants from the boats docked at the 58 slips that are proposed as part of the project in the marina basin. Additional water quality degradation also may result from boats that are moored at docks that may be constructed at a later date by the owners of the 44 lots adjacent to the canal, pursuant to the exemption in Section 403.813(2)(b), Florida Statutes. This exemption provides that private docks in artificially constructed waters are exempt from dredge and fill permitting and may be constructed without a permit providing they meet the size criteria listed in the statute and provided they do not impede navigation, affect flood control, or cause water quality violations. The boats in the canal system and boat basin would be a chronic source of pollutants for the life of the facility. The proposed water depths and slip sizes will make the basin accessible for use by large boats which can be expected to have on-board sanitation devices. The hydrographic report submitted by the applicant indicates the proposed waters will flush with a 2.6 hr. duration. Although this flushing rate will prevent water quality pollutants from being concentrated in the waters of the basin, it also will have the effect of transporting boat related pollutants to the Indian River, thereby causing degradation of the Outstanding Florida Water. The project site is within Class II Waters, prohibited for shellfish harvesting, but is adjacent to Class II Waters, approved for shellfish harvesting. Discussion with the Department of Natural Resources, Bureau of Regulation and Development, indicates that the pollutant loading from the project would probably cause the adjacent waters to be reclassified as "prohibited for shellfish harvesting." The reclassification of the adjacent waters would lower the existing use of the waterbody. Rules 17-302.300(1), (4), , and (6), Florida Administrative Code, state that: Section 403.021, Florida Statutes, declares that the public policy of the State is to conserve the waters of the State to protect, maintain, and improve the quality thereof for public water supplies, for the propagation of wildlife, fish and other aquatic life, and for domestic, agricultural, industrial, recreational, and other beneficial uses. It also prohibits the discharge of wastes into Florida waters without treatment necessary to protect those beneficial uses of the waters. * * * Existing uses and the level of water quality necessary to protect the existing uses shall be fully maintained and protected. Such uses may be different or more extensive than the designated use. Pollution which causes or contributes to new violations of water quality standards or to continuation of existing violations is harmful to the waters of this State and shall not be allowed. Waters having water quality below the criteria established for them shall be protected and enhanced. However, the Department shall not strive to abate natural conditions. If the Department finds that a new or existing discharge will reduce the quality of the receiving waters below the classification established for them or violate any Department rule or standard, it shall refuse to permit the discharge. As a result of the above cited factors, degradation of water quality is expected. The applicant has not provided reasonable assurance that the immediate and long-term impacts of the project will not result in the degradation of existing water quality in an Outstanding Florida Water and the violation of water quality standards pursuant to Rules 17-312.080(1) and (3), Florida Administrative Code, and Rule 17-4.242(2)(a)2.b, Florida Administrative Code. Specific State Water Quality Standards in Rules 17-302.500, 17-302.510 and 17-302.550, Florida Administrative Code, affected by the completion of the project include the following: Bacteriological Quality - the median coliform MPN (Most Probable Number) of water shall not exceed seventy (70) per hundred (100) milliliters, and not more than ten percent (10 percent) of the samples shall exceed a MPN of two hundred and thirty (230) per one hundred (100) milliliters. The fecal coliform bacterial level shall not exceed a median value of 14 MPN per 100 milliliters with not more than ten percent (10 percent) of the samples exceeding 43 MPN per 100 milliliters. Dissolved Oxygen - the concentration in all waters shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter. Normal daily and seasonal fluctuations above these levels shall be maintained. Oils and Greases: Dissolved or emulsified oils and greases shall not exceed 5.0 milligrams per liter. No undissolved oil, or visible oil defined as iridescence, shall be present so as to cause taste or odor, or otherwise interfere with the beneficial use of waters. In addition the applicant has not provided reasonable assurance that ambient water quality in the OFW will not be degraded pursuant to Rule 17-4.242(2)(a)2.b, Florida Administrative Code. In addition, pursuant to Rule 17-312.080(6)(a), Florida Administrative Code, the Department shall deny a permit for dredging or filling in Class II waters which are not approved for shellfish harvesting unless the applicant submits a plan or proposes a procedure to protect those waters and waters in the vicinity. The plan or procedure shall detail the measures to be taken to prevent significant damage to the immediate project areas and to adjacent area and shall provide reasonable assurance that the standards for Class II waters will not be violated. In addition to impacts to water quality, the project is expected to adversely affect biological resources. A portion (estimated at between 0.4 and 0.5 ac.) of the access channel alignment is vegetated by seagrasses, the dominant species being Halodule wrightii (Cuban shoal weed). Seagrass beds provide important habitat and forage for a variety of wildlife species. The loss of seagrass beds will result in a loss of productivity to the entire system that would be difficult to replace. The 4.72 ac. of wetlands proposed to be filled and the excavation required for the proposed channels (approximately 38 ac.) are productive high marsh and mixed mangrove wetlands which are providing wildlife habitat and water quality benefits. These wetlands have been adversely impacted by the freeze of 1989, but they appear to be recovering well. The proposed mitigation would provide some benefits through exotic removal and increased hydrologic connection to the Indian River. However, these benefits would not be adequate to offset the adverse impacts of the proposed wetland losses for this project. The project site and the adjacent Pelican Island National Wildlife Refuge are used for nesting and foraging by a variety of species, including little blue heron (Egretta caerulea) (Species of Special Concern (SSC)--Florida Game and Fresh Water fish Commission (FGFWFC)), reddish egret (E. rufescens) (SSC-FGFWFC), snowy egrets (E. thula) (SSC-FGFWFC), tricolored herons (E. tricolor) (SSC-FGFWFC), brown pelicans (Pelecanus occidentalis) (SSC-FGFWFC), roseate spoonbills (Ajaja ajaja) (SSC-FGFWFC), least tern (Sterna antillarum) (threatened-FGFWFC), and wood storks (endangered-FGFWFC). The construction of the project and the increased boating activity due to the project would result in the disturbance of those species that use the wetlands in the project area. The Indian River adjacent to the project site is used by the West Indian Manatee (endangered-FGFWFC). The increased boat traffic would increase the chance of manatee deaths due to boat impact. In addition, the excavation of the access channel through the seagrass beds would decrease the available forage for manatees in the project area. For the above reasons, this project is also not clearly in the public interest, as required pursuant to Section 403.918(2), Florida Statutes, because it is expected to: adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; be permanent in nature; diminish the current condition and relative value of functions being performed by areas affected by the proposed activity. The applicant has not provided reasonable assurance that the project is clearly in the public interest. On September 12, 1991, the owner and holder of the mortgage on the Orchid Island development (which includes the real property on which the Petitioner hopes to construct the project at issue in this proceeding) instituted foreclosure proceedings. The circuit judge who presided over the foreclosure proceeding soon thereafter appointed an interim receiver to manage the property until a receiver who would manage the property for the duration of the foreclosure proceeding could be appointed. THE PROJECT MODIFICATIONS AND FACTS AS TO ESTOPPEL On October 31, 1991, representatives of Orchid Island Associates met with Respondent's staff to discuss this application. Trudie Bell, the Environmental Specialist assigned to supervise this application, and Douglas MacLaughlin, an attorney employed by Respondent, attended the meeting. Those attending the meeting on behalf of Orchid Island Associates included the interim trustee, the attorney for Orchid Island Associates, and Darrell McQueen, who at all times pertinent to this proceeding was the project engineer. Mr. McQueen was upset that the project was going to be denied and wanted to know what could be done to make it a permittable project. In response to Mr. McQueen, Ms. Bell, without making any promises, suggested the following modifications to the project that might make it permittable: moving the canal more upland, elimination of the boat basin/marina, reducing the depth of the artificial waterway, and increasing the width of the littoral zone. On November 11, 1991, the representatives of Orchid Island Associates responded to the Respondent's suggested modifications and agreed to make the modifications. In an effort to design a project that would be acceptable to Respondent, Orchid Island Associates proposed to the Respondent to make certain modifications to the design of the project. Petitioner has agreed to those modifications which include the following: Elimination of the boat basin and associated 58 dock marina and clubhouse, but with the addition of 18 relatively narrow residential lots, each of which would have a dock on the south end of the waterway. 2/ Reduction of the depth of the artificial waterway to -7 feet NGVD from the proposed -8 feet NGVD. Realignment of the artificial waterway as depicted on the sealed drawings submitted to Respondent and dated January 28, 1993. Increasing the width of the littoral zone to be created along the length of the artificial waterway to 40 feet on the west side and 10 feet on the east side. On November 12, 1991, John C. Kurtz was appointed the receiver of the Orchid Island Associates property and remained the receiver until the property was conveyed to Petitioner at a foreclosure sale on July 31, 1993. After it acquired the property, Petitioner employed Mr. Kurtz to manage the subject property. Mr. Kurtz has been active in the project since his appointment as the receiver of the property. On November 21, 1991, Petitioner met with Respondent's staff, including Ms. Bell, to discuss the modifications. At that meeting, the Respondent's staff reacted favorably to the modifications agreed to by Petitioner. Ms. Bell described the revisions as "excellent" and "a great idea" and stated that the project was "a nice project" and that it looked like the project was heading in the right direction. Ms. Bell also represented that the Respondent would grant the Petitioner extensions of time to allow for a formal revision if the project was deemed permittable. Ms. Bell kept her superiors informed of the status of her review. On December 11, 1991, Charles Barrowclaugh, an employee of the Respondent, made an inspection of the site and informed representatives of the Petitioner that he had briefed Carol Browner, who was Secretary of the Department of Environmental Regulation, as to the project and the proposed modifications. Mr. Barrowclaugh stated that he believed the project was permittable. Petitioner was encouraged by Mr. Barrowclaugh's comments and by the fact that he would incur the expenses of traveling to the site. Between December 11, 1991, and November 13, 1992, Petitioner provided information to Respondent pertaining to the revised project. This additional information included a description of the revised plan and a revised schematic drawing, but it did not include detailed drawings of the revised project. On November 13, 1992, Ms. Bell wrote to Mr. McQueen a letter that stated, in pertinent part, as follows: The Bureau of Wetland Resource Management has reviewed the revised plan and additional information submitted on September 16. The revised proposal appears to address all of the issues that made the original proposal unpermittable. The detailed 8.5 by 11 inch permitting drawings will have to be revised to reflect the revised proposal and submitted to the Bureau for review. Kelly Custer and Orlando Rivera will be reviewing the project in the future. Petitioner interpreted that letter to mean that the Respondent intended to permit the project. At the time she wrote the letter of November 13, 1992, Ms. Bell thought the revised project would be permitted. Petitioner relied on the oral representations made by Respondent's staff and on the November 13, 1992, letter in continuing pursuit of a permit. Absent these encouraging comments by Respondent's staff, Petitioner would have discontinued pursuit of the permit. Although Petitioner was understandably encouraged by the discussions its representatives had with Respondent's staff, it knew, or should have known, that the favorable comments it was receiving from members of Respondent's staff were preliminary and that additional information would be required and further evaluation of the project would take place. Petitioner's representatives knew that the staff with whom they were having these discussions did not have the authority to approve the application, but that they could only make recommendations to their superiors. In late 1992, Kevin Pope, an Environmental Specialist employed by Respondent, was assigned as the primary reviewer of the revised project. At the time he became the primary reviewer of the project, Mr. Pope did not make an immediate, independent evaluation of the project, and relied on what other staffers who had been involved in the review told him. Until he conducted his own review of the project, Mr. Pope believed that the project was "clearly permissible". Mr. Pope informed a representative of the Petitioner of that belief and told the representative that he was prepared to start drafting the permit once he received final drawings documenting the modifications to the project. Subsequent to that conversation, Mr. Pope received the drawings he requested. After he received and reviewed the final drawings, Mr. Pope determined that all issues raised by the denial letter had not been addressed. Among the concerns he had was the fact that the project would dredge into the Indian River to the Intercoastal Waterway and that part of the dredging activity (at the north end of the project) would be in Class II shellfish approved waters. Mr. Pope again contacted the state and federal agencies that had originally commented on the project, described the proposed modifications to the project, and requested comments. Most of the agencies continued to object to the project. On August 5, 1992, Mr. Pope held a meeting with the commenting agencies and with representatives of the Petitioner to discuss the objections to the project. 3/ The agencies provided additional comments after this meeting and most continued to oppose the project. Mr. Kurtz testified that on June 1, 1993, Stacey Callahan, an attorney employed by Respondent, told him that she was attempting to draft the permit for the project. Ms. Callahan asked for sample wording for a restrictive covenant or for an easement that would limit the number of boats that could use the proposed docks. Subsequent to that inquiry, Petitioner was informed by Mr. Pope that the project would be denied. Petitioner has not made any specific proposal to assure a limitation on the number of boats that will be able to dock in the proposed canal. In June of 1993, a large number of objections to the project were filed with Respondent by members of the public. In early July, 1993, Secretary Wetherell responded to those objectors with a letter stating, in part, that the "Department's letter of November 1992 indicating an intent to issue for the project was imminent appears to have been premature." On September 20, 1993, Mr. Pope informed Petitioner's attorney that the Respondent was not going to change its position that the project, even with the modifications, should be denied. The decision not to permit the modified project was made by Mr. Pope. The only permit application filed by the Petitioner was the application for the initial permit. No formal amended application that incorporates all of the changes that Petitioner discussed with Respondent's staff was filed. A total of $74,735 was spent on behalf of the applicant on this project between December 26, 1991, (the date of the meeting with Mr. Barrowclaugh) and July 31, 1993, (the date the property was conveyed to Petitioner). From July 31, 1993, through April of 1994, Petitioner spent an additional $47,488 on the application for this project. The expenditures after July 31, 1993, included engineering costs that were incurred before that date. These figures do not include the costs of this proceeding. THE REVISED PROJECT The revised project may be summarily described as follows: Petitioner proposes to construct a canal that will be approximately 6,400 feet long, up to 200 feet wide, and -7 NGVD deep as depicted on drawings that have been submitted into evidence. There will be a littoral zone 40 feet wide on the west side of the canal and a littoral zone 10 feet wide on the east side. A hydrological channel, proposed from the north terminus of the canal to the Intercoastal Waterway to enable a proper flow of water through the canal, will be some 200 feet wide, 70 feet in length, and -3 NGVD. Petitioner proposes to construct a barrier at the north terminus of the canal to prevent manatees and boats from entering the canal from the north and has agreed to maintain that barrier. An access channel, proposed from the south terminus to the Intercoastal Waterway to enable boats access to the canal, will be some 200 feet wide, 700 feet in length, and -7 NGVD. A total of 62 docks are proposed. The project includes a mitigation plan that will be discussed below. THE REQUESTED VARIANCE The construction of the hydrological channel would be in Class II conditionally approved shellfish waters. Dredging in Class II conditionally approved shellfish waters is prohibited unless a variance is issued by Respondent that would permit this otherwise prohibited activity. Petitioner's attorney submitted a letter to the Respondent on August 18, 1993, for a variance to construct the channel from the north terminus of the canal to the Intercoastal Waterway. That letter stated, in pertinent part, as follows: DEP Rule 17-312.080(17) states: "Permits for dredging or filling directly in Class II or Class III waters which are approved for shellfish harvesting by the Department of Natural Resources shall not be issued." This provision is applicable to the pending application by Orchid Island Associates. Accordingly, we discussed Orchid Island requesting a variance pursuant to Section 403.201, Florida Statutes, and Rule 17-103.100, Florida Administrative Code, as a means of overcoming this prohibition. Since the dredge and fill application is pending, you indicated it would be appropriate for Orchid Island to ask, during final review of this application, that the Department also consider a request for a variance pursuant to the above mentioned statute and rule. Please consider this letter that request. . . . Petitioner did not submit along with its request the fee required by Respondent to process that request. Respondent did not advise Petitioner that it would not process its request without the requisite application fee until the prehearing stipulation was prepared for this proceeding shortly before the formal hearing. There was no evidence that Petitioner attempted to check on the status of its request for a variance or that it expected Respondent to act on the request for a variance independent of its final review of the overall project. As of the time of the formal hearing, Petitioner had not submitted to Respondent the fee that Respondent asserts is required before the request for the variance will be processed. Respondent asserted that position in the prehearing statement that was filed shortly before the formal hearing. The evidence as to the flow of water through the proposed canal assumed the existence of the hydrological channel from the north terminus of the proposed canal to the Intercoastal Waterway and the existence of the access channel from the south terminus of the proposed canal to the Intercoastal Waterway. CONSTRUCTION OF THE PROJECT The revised version of the artificial waterway will be excavated primarily from uplands, but the excavation will require that 3.6 acres of wetlands be filled and 7.1 acres of wetlands be dredged. The direct impact on wetlands will be at least 10.7 acres. The mitigation plan proposes that the berms around the mosquito impoundment will be leveled, the berm ditches will be filled, and certain rotary ditches will be dredged. The amount of wetlands to be impacted by that proposed activity was not established. The artificial waterway will be constructed utilizing a series of separate construction cells, a rim ditch, and filtration chambers. All excavated material will be disposed of on uplands. The construction system will filter most solids. Turbidity suppression devices will be used to minimize any turbidity associated with the excavation of the access channel at the south terminus and the hydrological channel at the north terminus. Petitioner established that its proposed construction techniques are consistent with best management practices. The small body of water that is referred to as the former borrow pit in the denial letter of September 12, 1991, is known as Boot Lake. Petitioner proposes to dredge the eastern end of Boot Lake, consisting of an area 800 feet by 180 feet (3.3 acres), to create part of the canal. The access channel at the south terminus of the canal will be approximately 700 feet in length and will have to be hydraulically excavated in the Indian River to connect the canal to the Intercoastal Waterway. The hydrological channel at the north terminus of the canal will be hydraulically excavated to connect the canal to the Indian River. The connection will require approximately 70 feet of dredging to -3 NGVD, which is the minimum necessary to maintain the proper flow of water through the canal. HYDROLOGY OF THE CANAL The artificial waterway will function as a flow-through system driven by a difference in the water surface elevation (the head difference) between the north terminus and the south terminus. The flushing of the artificial waterway far exceeds the Respondent's flushing requirement benchmark, which is a flushing time of four days. If a hypothetical pollutant's concentration is reduced to 10 percent of its initial concentration in four days, the flushing is considered to be acceptable. The flushing time for the system is approximately 2.6 hours, which will produce five total volume replacements per tidal cycle. The predicted flushing of the artificial waterway is quite rapid and energetic. The predominate flow of water in the artificial waterway is from north to south. At times, however, the flow will be from the south to the north. At the request of the Respondent, Petitioner conducted a tracer dye study within the Indian River at the proposed south terminus of the artificial waterway. No tracer dye study was requested for the north terminus. Although there was some disagreement as to the import of the tracer dye study, it established that pollutants introduced into the Indian River from the canal would be rapidly dispersed in the Indian River. WATER QUALITY - THE CANAL The artificial waterway will be classified as Class III waters of the State. Water quality within the artificial waterway will reflect the current water quality in the Indian River. Petitioner has provided reasonable assurances that the water quality within the artificial waterway itself will not violate state standards. Two potential sources of pollutants to the artificial waterway have been identified. The first source is stormwater runoff through the stormwater management system associated with the upland development. The second is pollution inherent with the docking and operation of large vessels. Respondent interprets its rules so that discharge of pollutants into the artificial waterway will constitute indirect discharges to the Indian River. Because of the excellent flushing capacity of the canal, pollutants will not tend to accumulate in the canal. A pollutant entering the canal or a spill of pollutants into the canal will mix very little in the canal, probably less than five percent, so the pollutant will discharge from the canal into the Indian River as a plug. There was a conflict in the evidence as to whether pollutants introduced into the canal will enter the Indian River in measurable quantities. Testimony was elicited from Dr. Roessler, one of Petitioner's experts, that water entering the Indian River from the artificial waterway will not contain pollutants that are either measurably or statistically differentiable from the Indian River itself. That result depends, however, on the amount and the source of the pollutant introduced into the canal. Because of the rapid flushing of the canal, small spills or slowly released discharges of pollutants are not expected to result in water quality degradation in the Indian River. Since a pollutant introduced into the canal will exit in a plug essentially in the same concentration as it entered the canal, Petitioner has not provided reasonable assurances that large spills or discharges of pollutants from vessels or from other sources will not be discharged into the Indian River in concentrations that can be measured or that such large spills or discharges will not degrade the quality of the Indian River. Water from the canal will come out of both the north end and the south end of the canal. Some of the plume coming out of the north end may tend to hug the shoreline, with some of the plume reentering the canal when the tides change. Stormwater runoff contains significant amounts of fecal coliform, sometimes more than raw sewage. The stormwater management system associated with the upland development was permitted by the St. Johns Water Management District. The majority of the system is currently in place and functioning to retain stormwater runoff. The stormwater management system is designed to retain all of the first 4.75 inches of rainfall and most of the first 6.2 inches of rainfall. The design of this system exceeds the requirements imposed by the St. Johns Water Management District, which is that the first 1.5 inches of rainfall be retained. Stormwater management regulations are technology-based treatment criteria. If a system meets the retention requirement, it is presumed that no water quality will be violated by discharges through the system. Petitioner established that the stormwater management system was designed and constructed to retain at least three times the amount of rainfall required by the St. Johns Water Management District. Construction of the proposed canal will intercept two stormwater discharge pipes from the upland golf course and residential development. There was no evidence that the St. Johns Water Management System has reviewed this change in the system that has been permitted. The proposed change in where the outflow will be discharged could be significant since the discharge pipes are presently designed to discharge overflows from the system into wetland areas that provided additional natural treatment of the overflow before the overflow reaches the Indian River. With this change the overflow will be discharged during extraordinary storm events into the canal and thereafter into the Indian River without additional natural treatment. Because there will be modifications to the stormwater system the approval of that system by the St. Johns Water Management District should not be relied upon as providing reasonable assurances that no water quality violations will be caused by stormwater discharge. If this project is to be permitted, Petitioner should be required as a condition precedent to the issuance of the permit to have the proposed changes to the system reviewed by the St. Johns Water Management District and it should be required to obtain an amendment to the stormwater management system permit that would authorize the proposed changes. The project contemplates the construction of 62 docks. The size and the docking capacity of each dock has not been established. While Petitioner presented testimony that it is likely that only 50 percent of the docks will likely be used at any one time, that testimony is considered to be speculative. The number and size of boats that can or will be docked in the canal at any one time or on a regular basis is unknown. It is likely that each dock will have docking capacity for at least one vessel up to 60 feet in length and for a smaller vessel. The manner in which these docks will be constructed was not established. Chromatic copper arsenic, which is frequently used to coat docks and anti-fouling paints containing heavy metals used on boats are sources of contamination to shellfishing. Oils and greases from boats contain hydrocarbons which can adversely impact shellfish. These contaminants can have adverse impacts to shellfish at very low concentrations. Petitioner has agreed to prohibit live-aboard vessels and to prohibit the fueling and maintenance of vessels within the artificial waterway. Sewage containing fecal coliform dumped or spilled from boats or from stormwater discharge is a primary source of contamination for shellfishing waters. It is the practice of the Respondent's Shellfish Environmental Assessment Section to close waters to shellfishing in the vicinity of marinas, mainly due to potential contamination from untreated sewage. The Shellfish Environmental Assessment Section does not recommend the immediate closing of shellfishing waters when a project involves single family docks associated with a residence because it assumes people will use bathroom facilities in the house instead of on the boat. The Respondent does not have reasonable assurances that there will be houses associated with each of the 50 foot lots designated at the southern end of the canal. If a proposed facility has boat docks, but does not have houses associated with each dock, the Shellfish Environmental Assessment Section would recommend closure of shellfishing in the vicinity of the facility. The Shellfish Environmental Assessment Section would not recommend immediate closure of the shellfishing waters in the vicinity of this proposed project because it has assumed that each of the proposed docks will be associated with a house. If this project is to be permitted, reasonable assurances should be required that a residence will be constructed before or contemporaneously with the construction of a dock. The modifications made by Petitioner to the project will reduce the danger of pollutants from vessels in the artificial waterway. However, because the number and the size of the vessels that will be using the artificial waterway was not established, the extent of pollutants from vessels is unknown. Consequently, it is concluded that Petitioner did not provide reasonable assurances that measurable pollutants would not indirectly discharge into the Indian River from the canal. IMPACT ON WETLANDS Of the approximately 10.70 acres of wetlands that will be directly impacted by the proposed waterway, 4.10 acres are predominately impacted by invasive exotic (non-native) plants, 4.27 acres are somewhat impacted by exotic plants, and 2.23 acres are not impacted by exotic plants. The exotic plants found at the project site are primarily Australian Pine and Brazilian Pepper. The mitigation plan, which will be discussed below, proposes that the berms constructed around the mosquito impoundment area be removed and the rim ditches that abut the berms be filled. The amount of wetlands to be impacted by that activity was not established. The project contemplates that rotary ditches will be constructed at different places in the mosquito impoundment area after the berms are removed and the berm ditches filled. The areas to be impacted by the construction of the rotary ditches were not identified. The Petitioner proposes to dredge out the entire east end of Boot Lake for use as part of the canal. This area will be approximately 800 feet by 180 feet and will be 3.3 acres. Boot Lake is a fairly healthy biological system, about the same as the Indian River. It was found to contain 22 species of fish and seven species of birds, with brown pelican and the great blue heron dominant. Eleven species of crustacean, six species of mollusks, 24 vermes 4/ and one coelenterate were collected from the lake. Replacement of the eastern portion of Boot Lake with the canal will adversely impact those species. Between the Indian River and the proposed waterway is a mosquito impoundment constructed in the early 1960s. The mosquito impoundment and associated berms total approximately 105 acres. The exact area was not established since there is an unresolved issue as to the exact location of the mean high water line. 5/ The impoundment is breached in several locations and no longer functions efficiently as a mosquito impoundment. IMPACTS ON SEAGRASSES The excavation of the access channel from the south terminus to the Intercoastal Waterway will involve the removal of approximately 2500 square feet of a healthy, productive seagrass bed. Seagrasses are beneficial for wildlife habitat as they provide a substrate for algae and diatoms. Seagrasses are a direct food source for manatees and other species, and provide shelter and protection for fish. Seagrasses observed in this area where grasses will be eliminated are Halodule writtii, Syringodium filiforme, and Halophia johnsonii. Halophia, one of the identified species in this seagrass bed, is designated by the Florida Natural Areas Inventory as a rare and endangered species. Besides the seagrasses actually eliminated where the channel is to be constructed, other nearby seagrasses are also likely to be affected. The sides of the channel are likely to slough to some degree, which would adversely impact the seagrasses abutting the channel. The operation of power boats, even at slow speeds, will cause turbidity that will likely adversely impact seagrasses. Maintenance dredging, which will be required every few years, will cause turbidity that will likely adversely impact seagrasses. There are presently thousands of acres of seagrasses located within the Indian River. There has been a historical decline in seagrass in the Indian River Lagoon. Since 1950, there has been a 30 percent loss of seagrasses and seagrass habitat. IMPACTS ON SHELLFISH The proposed project will have an adverse impact on shellfish and shellfishing. At a minimum, the project will require dredging in a shellfishing area. The hydrological channel that will be dredged to connect the north terminus of the canal with the Intercoastal Waterway will be located in Class II waters that have been conditionally approved for shellfishing. Both commercial and recreational shellfishing occur in the Indian River adjacent to the project site. The predominate flow of water through the canal will be southerly. There will be, however, a predictable northerly flow of waters that will cause waters from the proposed canal and any associated contaminants contained in those waters to flow from the north terminus of the canal into the Class II waters that have been conditionally approved for shellfishing. The proposed project may introduce a significant amount of freshwater into the adjoining shellfishing waters of Indian River, primarily in the vicinity of the north terminus of the canal. Any additional freshwater discharges to shellfishing waters is a concern because fecal coliform bacteria survive longer in freshwater than saltwater. Three likely sources of freshwater that would be added by this project to the Indian River in the conditionally approved shellfishing area were identified by Respondent. First, the proposed canal appears to be intersecting near its north terminus with a sulphur spring or artesian well which produces fresh water with a high sulphur content. Fresh water will likely be introduced into the canal from this source and discharged into the shellfishing waters when the tidal flow becomes northward. Second, freshwater may be introduced into the canal from the overflow pipes from the surface water management system. This source of freshwater would not be significant. Third, additional freshwater may enter the area after the berms around the mosquito impoundment area are removed as contemplated by the mitigation plan. The extent of this source of freshwater was not established. If this project is permitted, the Shellfish Environmental Assessment Section will monitor this area for water quality to determine if the area will have to be closed for shellfishing. This additional monitoring, for which Respondent will pay, will be required because of the potential adverse impacts this project presents to shellfishing. Because of evidence of deteriorating water quality, the Shellfish Environmental Assessment Section is recommending that the shellfishing waters adjacent to the site be reclassified from "conditionally approved" to "conditionally restricted". In "conditionally restricted" waters, shellfish can still be harvested, but the harvested shellfish have to be placed in designated waters or in on-land facilities so the shellfish can cleanse themselves of fecal coliform before going to market. The conditions in the area of the proposed project are not yet bad enough to prohibit shellfishing. IMPACT ON MANATEES There are approximately 2,000 manatees living in Florida waters, with approximately 1,000 living on the east coast and approximately 1,000 living on the west coast. The manatee is an endangered species, and the long-term survival of the species is not secure. The Indian River in the area of the proposed project provides good habitat for manatees and is a major travel corridor for several hundred manatees. Indian River County is one of 13 key counties that has been designated by the Governor and Cabinet to address special manatee concerns. Manatees traveling back and forth in this area usually use the channel of the Intercoastal Waterway because it is deeper and allows manatees an easier travel route. Speed zones for boat traffic are an effective manatee protection mechanism. The artificial waterway will be posted as an idle speed zone. The area where the access channel connecting the south terminus of the canal with the Intercoastal Waterway will be dredged is presently designated as a slow speed zone and the access channel itself will be marked. Petitioner has agreed to implement Respondent's standard manatee conditions. Seagrasses are an important source of food for manatees. The project contemplates that 0.05 acres of seagrass will be dredged, but that Spartina will be planted in parts of the littoral zone. While manatees eat Spartina to some extent, they prefer seagrasses. Since there are thousands of acres of seagrass located in the Indian River, it is concluded that the elimination of 0.05 acres of seagrass associated with this project is negligible and will not adversely affect manatees. A barrier to navigation will be maintained at the north terminus of the waterway to preclude boat access and limit access to the waterway by manatees. Manatees would be unable to enter or leave the artificial waterway via the north terminus. The artificial waterway will not attract manatees and should not, in and of itself, adversely impact manatees. The main adverse impact to manatees from this proposed project is the threat of collisions by boats that leave the canal and enter the waters of the Indian River, including the Intercoastal Waterway. At least ten West Indian manatees have been killed by boats in Indian River County since 1981. Even with the speed limits, the increase in boating in this area will present an increased risk to manatees. IMPACT ON BIRDS No species of wading birds, including those listed as endangered or threatened, nests or roosts within the project site. The project site is not currently heavily utilized by wading birds, but several species of wading birds were observed foraging for food in Boot Lake. It is reasonable to expect that dredging of Boot Lake and the increased boat traffic will have an adverse impact on birds. Diving birds, such as the brown pelican and least tern, will benefit from the increased open waterway created by the canal, which should serve as a feeding habitat. Wading birds congregate and nest in rookeries. The area of the proposed project is within the foraging range of 14 active rookeries, and it is reasonable to expect that those rookeries will be disturbed by the increased boat use or human activity that the project will bring to this area. Officials of Pelican Island National Wildlife Refuge have observed such disturbances and are opposed to this project. The pressure of human and boating activities on bird rookeries in the Pelican Island National Wildlife Refuge, including human intrusion into buffer zones established to protect the birds, has resulted in a continuing decline of the bird population since 1960. When disturbed by boats or by humans, the parent wading bird will often leave the nest, which exposes the eggs or the chicks to attack by predators or to overexposure to sunlight. Boaters will often cause wading birds who are foraging for food to flush, which disturbs their search for food. Certain species of wading birds are flushed more frequently and for longer distances when flushed from narrow tidal creeks in Spartina marshes (a habitat similar to the proposed canal) than in open shoreline habitat. IMPACT ON FISH The existing ditches inside the mosquito impoundment berms presently provide a habitat similar to that of a tidal creek for a variety of fish, including juvenile snook, tarpon, red drum, black drum, lady fish, and mullet. The proposed project will result in the filling of these habitats and impoundments. As a consequence of that activity, these species of fish will be adversely impacted by the project. Although Petitioner proposes to construct certain rotary ditches that it asserts would provide a habitat similar to that provided by the existing ditches, Petitioner has not submitted any plans or drawings or other specific information concerning these rotary ditches and has not provided reasonable assurances that these proposed rotary will replace the habitat that will be eliminated by the filling of the existing ditches. CUMULATIVE IMPACTS Other projects have been permitted on the Indian River north and south of the proposed project that have increased boat traffic on the Indian River in the vicinity of the project. The Respondent has not identified any similar projects which have been permitted in the vicinity within the last five years. The only similar application pending before the Respondent in the vicinity of the project is for two docks north of the project site. Although Respondent established that boat traffic on the Indian River has increased, this project is unique in scope and design, and it is concluded that Petitioner has given reasonable assurances that no negative cumulative impacts will be associated with the project. OTHER PERMITTING CRITERIA The parties stipulated to the following facts that pertain to permitting criteria: The project will not adversely affect navigation or the flow of water. The project will not cause harmful erosion or shoaling. The project will be of a permanent nature. The project will not adversely affect any significant historical or archaeological resources. The project will not adversely affect the property of others. The proposed waterway will be located almost entirely on private property in areas not currently utilized for fishing or other recreational activities. Except for the impacts on shellfishing, birds, and fish discussed above, the project will not adversely affect the fishing or recreational values within the vicinity of the project. THE MITIGATION PLAN Petitioner has taken all reasonable steps to minimize the adverse impacts associated with the type project it is proposing. Because there will be adverse impacts to an Outstanding Florida Water, the project can be permitted only if it is determined that the mitigation plan offsets the adverse impacts and makes the project clearly in the public interest. Petitioner's mitigation plan was contained in the original application and was revised between October 1991 and January 1992. Respondent considered the current mitigation plan in its review of this project. The current mitigation plan consists of the creation of wetlands, the enhancement of wetlands, and the preservation and donation of wetlands owned by Petitioner within the mosquito impoundment. The estimated cost of creation and enhancement of the mitigation plan is $600,000. Petitioner proposes to create approximately 14 acres of wetlands by removing the mosquito impoundment berms and converting other uplands within the impoundment to wetlands. These areas will be revegetated with various wetland plant species including red, black, and white mangroves. In addition, Petitioner proposes to create a forty foot wide intertidal littoral zone along the entire length of the western side of the artificial waterway and a ten foot wide littoral zone along the entire eastern side of the artificial waterway. Approximately three acres of the littoral zone will be created from uplands. The littoral zone will be revegetated with 80 percent cord grass and 20 percent red mangrove. Petitioner proposes to implement an open marsh mosquito control management program consisting of the elimination of natural accumulations of water in low lying areas within the impoundment by rotary ditching small channels to allow these areas to drain and to allow predator fish access to the areas. Petitioner will remove exotic plant species throughout the impoundment and will revegetate with native species such as red, black, and white mangroves. Petitioner proposes to monitor the project area to assure that exotic plant species do not re-colonize. The mosquito impoundment area and the associated berms is estimated as being approximately 105 acres. Because of the difficulty in determining the mean high water line and because of the number of breaches in the berms, the precise acreage within the impoundment area that is not currently sovereign lands was not established. If accurately surveyed, it is possible that the amount of acreage within the impoundment owned by Petitioner may be determined to be up to 10 percent less than is currently estimated. For the purposes of this proceeding, it is found that 105 acres is a reasonable estimate of the area of the impoundment owned by Petitioner. After completion of the enhancement program, Petitioner proposes to donate all the property it owns within the impoundment to the State of Florida. Petitioner asserts that it would have the right to construct single family docks from its property directly into the Indian River if this project is not permitted and that these docks would not be subject to Respondent's permitting jurisdiction. The construction of such docks would have an adverse impact on manatees and seagrasses. As part of its mitigation plan, Petitioner offers to waive its right to construct single family docks from its property directly into the Indian River. EVALUATION OF THE MITIGATION PLAN The wetland in the existing impoundment area is presently a good biological system that contains a good diversity of plants and animals. While Petitioner's proposals will enhance this area, the evaluation of that enhancement should take into consideration the quality of the existing system. There are at least three existing breaches in the berm system. Through these breaches there is some tidal influences and the export of detrital material. Because of the relatively isolated nature of the mosquito impoundment, it currently contributes little to the productivity of the Indian River. The removal of the berm system will result in greater tidal influence in the impoundment area. As a consequence, much of the leaf litter from mangroves within the impoundment that presently accumulates on site would be exported as detrital material to the Indian River, which will add material to the food chain. It is expected that increased tidal influence will also result in an improvement in the dissolved oxygen levels within the impoundment. The reestablishment of tidal influence within the impoundment area will increase habitat for fish, shrimp, and crabs, and therefore benefit the Indian River. Removal of the impoundment berms to reestablish tidal influences within the impoundment area will increase and improve feeding and forage habitat for wading birds. Consequently, wading birds that nest in the vicinity of the project will be benefited. Increased tidal influence will likely result in better growth for mangroves which would create roosting sites for wading birds where none presently exist. Currently, Australian pines are the dominate species in areas within the impoundment area. Other areas of the impoundment are heavily populated by Brazilian pepper. Australian pines and Brazilian peppers do not serve as food sources for any native wildlife and have the potential to crowd out native plant species such as mangroves. If not removed, the potential exists for Brazilian pepper to become the dominate plant species. Removal of exotics and replanting with native species is a benefit to the Indian River system. With an appropriate monitoring plan, the exotic removal should be successful. If the project is permitted, the implementation of an appropriate monitoring plan should be a condition of the permit. Because of widespread mosquito control activities, the high marsh ecosystem is now rare in the Indian River system. The restoration of the impoundment area to an area of high marsh would be of benefit to the Indian River ecosystem. Prior to alteration by man, the mosquito impoundment was a high marsh ecosystem consisting primarily of black and white mangroves over an understory of succulent plants. There was a conflict in the evidence as to whether the Petitioner's proposals would result in the impoundment area returning to a high marsh area. While the impoundment area will be enhanced by the Petitioner's proposals, it is found that whether the area will be returned to a high marsh system is speculative. The mosquito impoundment is breached in various locations and, as a consequence, the impoundment is not functioning to control mosquitoes as it was originally designed. The current primary mechanism for mosquito control within the breached mosquito impoundment is aerial spraying of insecticides. The proposed removal of the existing berms will not adversely affect mosquito control and may positively affect mosquito control due to the increased accessibility of the impoundment by natural predators such as fish. This open marsh management plan is an effective means of controlling mosquitoes. The wetland creation proposed by Petitioner should have a high rate of success. Petitioner has agreed to implement a suitable monitoring plan to further guarantee the success of the proposal. If the project is permitted, the implementation of a suitable monitoring plan should be a condition of the permit. Scraping down the mosquito berms will create more wetlands, but the earth from the berms will be placed in the adjacent ditches, which presently serve as valuable tidal creek type habitat. Therefore, the mitigation itself will have some adverse impact. Petitioner's unspecified proposal to put in some rotary ditches to offset the loss of tidal creek habitat is inadequate in that there has been no specific proposal as to the location, size, shape, configuration, or acreage of the proposed rotary ditches. While planting of the littoral zones on the edges of the canal with Spartina provides some biological value, the growth of Spartina on the ten foot ledge on the east side will be impacted by boats and docks. The littoral zones will likely perform valuable wetland functions if properly planted and monitored and will likely become a productive wetland system that will provide habitat for wading birds. If the project is permitted, the Petitioner should be required to monitor the Spartina planting to ensure its successful growth. Even if the creation of the 13.9 acres of wetlands is successful, it will take years to become a mature biological system similar to the wetlands they are to replace. This time lag should be taken into account when evaluating the mitigation plan. There are adverse impacts from this proposed project that the mitigation plan does not offset. The mitigation plan does not offset the elimination of seagrasses, the loss of the Boot Lake habitat, the potential adverse impacts to shellfish and shellfishing, or the impacts to manatees. It is likely that property owners wishing to construct docks directly into the Indian River would have to get a permit from Respondent to gain access to the parts of the property where these docks could be constructed. Any proposal to extend docks into the Pelican Island National Wildlife Refuge would likely be prevented by the U.S. Fish and Wildlife Service. Whether such docks would, or could, be constructed is speculative, and this portion of the mitigation plan should be accorded little weight. As part of its mitigation plan, Petitioner proposes to donate approximately 105 acres to the State of Florida. This is considered to be a favorable aspect of the mitigation plan. The central issue in this proceeding is whether the mitigation plan offsets the negative impacts of this project so that the project becomes "clearly in the public interest." This issue is resolved by finding that even when the mitigation plan and the conditions that are recommended herein are considered, this project is "not clearly in the public interest."
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Respondent enter a final order that adopts the findings of fact and conclusions of law contained herein and which denies the modified application for the subject project. DONE AND ENTERED this 31st day of August 1994, in Tallahassee, Leon County, Florida. CLAUDE B. ARRINGTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 31st day of August, 1994.
Findings Of Fact Joyce K. Anderson and Thomas Barnett have filed an application for issuance of a permit to dredge and fill a small area in the littoral, or "near shore," zone of Gillis Pond, a "sandhill lake" lying in what is known as the "sandhill region" of Central Florida, generally northeast of Gainesville. The dredging and filling as now proposed would be on and waterward of two lakefront lots jointly owed by the permit applicants. They seek by their application, authorization to dredge and fill at only one site on the waterward margin of the two lots with that modified project area reduced in size to a dimension of 12 feet by 25 feet. Fifteen feet of the project would be waterward of the shoreline. The Respondent, the Department of Environmental Regulation, is an agency of the State of Florida charged with the duty of enforcing, as pertinent hereto, the provisions of Chapter 403, Florida Statutes, and Chapter 17-3 and 4, Florida Administrative Code, enforcing the water quality standards contained therein as they relate to dredge and fill projects of this sort, with concomitant permitting jurisdiction over such projects. The permit applicants desire this dredge and fill permit in order to make a safe, comfortable swimming area for Mrs. Anderson's family and friends. Mrs. Anderson desires to remove the tree stumps, roots and vegetation existing in the littoral zone area of the above dimensions in order to make access directly from the shore more comfortable and pleasant, especially for small children who are unable to swim in the deep water off the waterward end of the existing dock. Mrs. Anderson already has a 56 foot dock extending from her property into the lake. The water is 7 feet deep at the waterward end of the dock and the littoral zone containing aquatic vegetation extends beyond the length of the dock in a waterward direction. The project area would extend waterward of the shoreline, a distance of 15 feet, and would parallel the shoreline approximately a distance of 12 feet. The littoral zone vegetation at the site, however, extends waterward from the shoreline 50 to 60 feet. The proposed area to be dredged is quite small in size in relation to the total linear shoreline of the subject lake of approximately 4,000 feet. The dredged material would be excavated to a depth of approximately 6 inches over that 12 by 15 foot area and replaced with clean sand fill. The dredged material removed from the site would be secured on an upland site such that nutrient pollutants from that dredged material could not be leached or carried back into the lake through storm water runoff. Approximately one-third of the shoreline of the lake is bordered by a marsh or wet prairie which is approximately as large in area as the lake itself. The dominant vegetative species in the project area and surrounding the lake, including the marsh, are submerged freshwater species listed in Rule 17- 4.02(17), Florida Administrative Code, including maidencane, sawgrass and a rare aquatic plant, websteria confervodies. Gillis Pond is a Class III water of the state, although its water quality parameters, or some of them, clearly exceed in quality, the minimum standards for Class III waters. Gillis Pond is what is termed an "ultra- oligotrophic lake, which means that its waters are characterized by a high level of transparency and very low nutrient content, that is to say that they are essentially pristine in nature. An oligotrophic lake such as this is very sensitive to any addition of nutrient pollutants. Even a small addition of nutrients to such water can cause an imbalance in the fauna and flora which have evolved to become dependent upon a low nutrient aquatic environment. Specifically, the rare aquatic plant named above is very sensitive to any enhanced nutrient levels and thus serves as a barometer of the water quality in this body of water. The addition of any nutrient pollutants to the lake, even in small amounts, might alter the chemical balance of the water in a derogatory manner so that the websteria confervodies might be eliminated. The elimination of this species from the littoral zone vegetation band surrounding the lake would likely result in other forms of vegetation supplanting it, altering the balance and makeup of the community of fauna and flora native to the lake and possibly hastening the progress of the lake toward eutrophication and degradation. The present water quality in the lake is such that dissolved oxygen and other criteria are better than the Class III water quality standards. The vegetation in the littoral zone of the lake and extending out as much as 50 to 60 feet waterward performs a significant function in uptaking and fixing nutrient pollutants that wash into the lake from storm water runoff from the surrounding uplands. Inasmuch as 30 to 40 feet of this belt of littoral zone vegetation would remain waterward of the dredged and filled area if the permit is granted, the nutrient uptake function of the vegetation in the littoral zone would not be significantly degraded. There are two locations where littoral zone vegetation has been removed in a similar fashion and water quality and flora and fauna communities characteristic of an oligotrophic lake are still present and healthy. Further, there is an extremely low nutrient level in the lake at the present time, and no significant amount of nutrient pollutants are leached or washed into the lake through septic tanks, storm water runoff or other sources. There is no question that the project as proposed would result in some slight, transitory degradation of water quality in the form of increased turbidity and reduced transparency. Turbidity will be caused during and shortly after the dredging and filling operation itself, caused by stirring up of bottom peat or sediments and by removal of a 12 by 15 foot area of aquatic vegetation in the littoral zone of the lake. Turbidity curtains in still waters such as involved here, can substantially reduce the spread of turbidity caused by the stirring up of bottom material and can substantially reduce the period of its suspension in the water by containing it at the dredged site. The vast majority of the littoral zone vegetation surrounding and waterward of the area to be dredged will remain such that the nutrient uptake function will be essentially undisturbed, thus any adverse impact on water quality will be insignificant. In terms of cumulative effect of allowing a multiplicity of such projects, not even a 10 percent loss of the littoral zone band of vegetation in the lake, which would be the maximum possible loss if all riparian land owners were allowed a similar size dredged and filled area on the front of their lots, would cause a violation of Department water quality standards. Parenthetically, it should be pointed out that such riparian owners cannot be prevented by any water quality criteria in Chapter 403 or Chapter 17, Florida Administrative Code, from having access to the lake in front of their lots. Such human traffic will have the gradual affect of destroying a significant amount of the littoral zone vegetation on and waterward of those lots (which is a cause and result the Department is powerless to regulate). By confining the destruction of littoral zone vegetation to such a small area as that involved in the application at bar and thus guaranteeing adequate, comfortable access for the riparian owner, the survivability of the remaining critical littoral zone vegetation will be significantly enhanced.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence in the record and the candor and demeanor of the witnesses, it is, therefore RECOMMENDED: That the application of Joyce K. Anderson and Thomas Barnett for a dredge and fill permit as described in the modified and amended application be GRANTED; provided, however, that turbidity curtains are used during all dredging and filling activity and for a reasonable time thereafter until turbidity caused by the project has settled out of the water column.

Findings Of Fact On November 1, 1982, Respondent Janson filed a Joint Application for a dredge and fill permit from Respondent, Department of Environmental Regulation, and from the Department of the Army Corps of Engineers. The project described in that application involved the construction of an approximately 1,000-square- foot, pile-supported residence, landward of the mean high water line but within the landward extent of Robinson Creek in St. Johns County, Florida. The proposed project also involved the placement of approximately 35 cubic yards of fill and a 30-foot culvert within a small (approximately 4-foot), tidally- influenced roadside ditch for driveway access and parking. The original application sought permission to place part of a concrete driveway and tool shed within the landward extent of Robinson Creek. The project is to be constructed on Lot 47, J.A. Lew Subdivision. Respondent Janson owns Lot 47, as well as Lots 45 and 46, which lots are north of and adjoining Lot 47 and also adjoining Robinson Creek. The next adjoining property owner to the north is the City of St. Augustine, Florida, which presumably owns the street. The adjoining property owner to the south of Lot 47 is Virginia P. Melichar. Neither Melichar nor the City objected to the Department's approval of the dredge and fill permit application. In support of his application, Janson retained the services of a registered surveyor and civil engineer, who performed a survey on Lot 47 to determine the location of the mean high water line with reference to the proposed project. That expert determined the location of the mean high water line to be at elevation 2.4 feet. Accordingly, all work contemplated by the dredge and fill permit is upland from the mean high water line. T.J. Deuerling, an environmental specialist for Respondent, Department of Environmental Regulation, visited the project site on December 13, 1982 and on December 30, 1982 in order to prepare the Department's Biological and Water Quality Assessment. As a result of those site visits, Deuerling recommended to Respondent Janson that he modify his permit application by moving the concrete slab and tool shed from the marsh area onto the uplands. Janson did so revise his application. In spite of the name of the permit being sought by Respondent Janson, the project involves no dredging. However, the culvert and its attendant fill would be placed in the man-made roadside ditch. That ditch constitutes a very weak transitional marsh. Although the culvert will eliminate some vegetation within that ditch, the effect of the elimination will be insignificant on water quality. The pilings for the pile-supported residence will also eliminate a small area of marsh. The anticipated shading caused by the pile-supported residence may impact somewhat on the vegetation in a small area below the residence; however, due to the fact that the floor of the house will be eight feet above the ground, light will still be able to penetrate. Therefore, the vegetation below the pile-supported residence will continue to act as a filter for pollutants. Janson has mitigated the small loss in wetlands by modifying his project so as to remove the concrete slab and tool shed from the marsh area to the uplands. Due to the project's small size, no storm water impact can be expected. Additionally, no evidence was introduced to show a violation of any water quality standard as a result of the proposed project. On March 16, 1983, Respondent, Department of Environmental Regulation, executed its Intent to Issue the dredge and fill permit in accordance with the revised application and subject to the conditions that: (1) turbidity curtains be employed in the ditch during the placement of fill over the culvert to contain any turbidity generated, and (2) construction on the uplands be confined to periods of normal water level conditions. On July 5, 1983, the Department of the Army Corps of Engineers issued its Permit and Notice of Authorization. The essence of the testimony presented by the Petitioners, including that of the employees of the St. Johns River Water Management District, who testified in opposition to the proposed project, is that even though Janson's proposed project would not impact water quality in a way that was either significant or measurable (although no one even suggested any specific water quality standard that might be violated), approval of Janson's permit might set a precedent for other projects which might then have a cumulative impact in some unspecified way at some unspecified location. No evidence was offered to show that Respondent, Department of Environmental Regulation's review of permit applications is other than site specific. Further, no evidence was introduced to show any proposed project anywhere having any impact with which Janson's project could be cumulative. Petitioners Sandquist and Shuler live in the neighborhood of the proposed project, perhaps as close as two blocks away.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered dismissing with prejudice the petition filed herein as to each individual Petitioner and issuing a dredge and fill permit to Respondent Janson in accordance with his revised application.

The Issue The disputed issues are as follows: Whether the proposed Water Conservation Plan is sufficient to meet the requirements of the District rule; Whether the proposed pumping will adversely affect wetlands and wetland vegetation in contravention of District rule; Whether the permit applicant has provided reasonable assurance of entitlement to the requested permit as required by the District rule; and What limiting conditions pursuant to Rule 40C-2.381, F.A.C., should be imposed on the Consumptive Use Permit (CUP).
Findings Of Fact THE PARTIES The Commission was created by the legislature pursuant to Public Law 67-1754 in combination with Public Law 85-503. Its principal office is located in New Smyrna Beach, Volusia County, Florida. The Commission is charged with maintaining a water supply and providing wastewater treatment and electrical power. The District is an agency created pursuant to Chapter 373, Florida Statutes, in charge of regulating, among other things, consumptive uses of water in a 19 county area of the State of Florida, including all of Volusia County. The geographical boundaries of the District are described in Section 373.069(2)(c), Florida Statutes. Vernon and Irene Beckham are property owners of the property proposed for the construction of the new State Road 44 wellfield. Volusia City-County Water Supply Authority is a cooperative created by interlocal agreement in accordance with Section 163.01, Florida Statutes (1991), which party made no appearance at the Formal Administrative hearing but adopted the position of the Commission. Nassau is an individual residing at 4680 Cedar Road, New Smyrna Beach, Florida. THE APPLICATION The present service area of the Commission encompasses approximately 43 square miles, of which only about 15 square miles of the service area are located in the City of New Smyrna Beach. On August 8, 1984, the District issued Consumptive Use Permit No. 2- 127-0214NG to the Commission for its Glencoe and Samsula wellfields, which permit would expire in seven years. The combined authorized withdrawal of the existing wellfields is 5.2 mgd on an average day and 8.31 mgd on a maximum day. In December 1990, the Commission submitted its Consumptive Use Permit Application to renew the existing permit, including the development of an additional water supply wellfield. This application also sought an increased allocation to meet projected demand for the Commission's service area. The total allocation sought was 5.59 mgd on an average day and 8.31 mgd on a maximum day. However, the District has recommended 5.29 mgd on an average day and 7.62 mgd on a maximum day by 1998. The source of the water for all three wellfields is the Floridan aquifer. The Floridan aquifer can produce the volumes of water requested based on the past pumpage from the Samsula wellfield and the Glencoe wellfield. The Glencoe wellfield has been in operation since early 1950. The Samsula wellfield has been in operation since 1982. The Commission has never exceeded the currently permitted withdrawals as measured by annual, daily, or peak basis. WATER DEMAND Approximately 75% of the demand is related to residential consumption. Approximately 10% of the demand is related to commercial and industrial consumption. Approximately 7% of the demand is related to irrigation. Lastly, approximately 8% of the demand is for miscellaneous consumption, including loss that occurs in the treatment process itself. Gross water use in the area served by the Commission is about 138 gallons per person per day. The approximate 103 gallons per person per day (net) used by residences is small as compared to other providers of potable water. The present population of the Commission's service area is approximately 31,570 customers. The projected 1997 population of the Commission's service area is 40,680. The Commission's population projections were obtained by methods consistent with the District's Permit Manual. VI. PERMIT CRITERIA Water Conservation Plan The Commission has submitted a complete Water Conservation Plan. The implementation of that plan is a condition of the permit. The Water Conservation Plan includes a customer audit program of the system to determine how much water is pumped and where the water goes once it is distributed. The customer audit program involves employees of the Commission discussing the historical water usage with the customer, detection of leaks, installation of water restrictors, and the prevention of freezing pipes in the wintertime. The Commission encourages reduced consumption through the water meter charges. Larger meters use more water than smaller meters. The monthly charge for the larger meters is higher thereby encouraging the use of smaller meters. The Water Conservation Plan includes a pressure monitoring program to detect leaks in the system. The program has been implemented. The system pressure monitoring plan measures the pressure in different zones around the Commission's service area and, should a large main burst, an alarm is triggered. Repair of that water main would occur immediately. The Water Conservation Plan includes an analysis of the economic, environmental and technical feasibility of using reclaimed water in Commission's Exhibit No. 14, Reuse of Reclaimed Wastewater Conceptual Planning Document. The Reuse of Reclaimed Wastewater Conceptual Planning Document involves four major phases of construction starting in 1991 with completion in 1995. The first phase is underway. As part of the reuse plan, the Commission is modifying the wastewater treatment plant to accept reuse water. The construction is 99 percent complete. A total cost for that is approximately 1.5 million. The Commission will be replacing some freshwater irrigation sources with reclaimed water. The Commission has valid DER permits for this use of reclaimed water. As part of the reuse plan, the Commission has entered into construction contracts to serve the municipal golf course, the landscape at city hall and city parks with wastewater. The transmission and distribution lines will be completed before October 1992. The cost is approximately $700,000. Other phases of the reuse plan include construction of the major infrastructure inside and outside the city for reuse distribution. Total investment is in excess of five million dollars. Major customers along the route have been identified to increase the demand on the reuse system. The Water Conservation Plan includes an employee awareness program and an educational program as well as a time frame to implement those programs. The Commission has a public relations program to inform the customers about water conservation which includes newspaper publications concerning reading water meters, xeriscaping, and methods to reduce water consumption and the time/temperature machine which has prerecorded messages. The Commission has a program for educating the public and encouraging xeriscaping or the use of drought resistant foliage. Xeriscaping is implemented at the wastewater lift stations. The Commission has used direct mailing to provide water conservation information to customers. The Commission has a program for inspecting and replacing defective meters. If a meter malfunctions, the replacement reduces the system losses and accurately records water usage. The Commission has a program to monitor unmetered uses, which includes reporting from users such as the fire department of their unmetered use. On a monthly basis, the fire department reports its water usage as calculated by its operation schedule. The Commission is using the lowest acceptable quality water source, including reclaimed water, for certain types of needs such as irrigation of golf courses. The Water Conservation Plan addresses the use of treated effluent to minimize withdrawals of groundwater. Issues Related to Reasonable Assurance Hydrogeology The Floridan aquifer occurs at approximately 100 feet below the land surface throughout Volusia County. It's overlain by approximately 100 foot of sandy and clayey material collectively called the Clastic aquifer or the surficial aquifer. The proposed SR 44 wellfield site is underlain by an approximate 900- foot depth of freshwater of the Floridan aquifer. In the high recharge area of the Deland Ridge, water moves rapidly into the surficial aquifer and recharges the Floridan aquifer. A regional groundwater gradient extends from the Deland Ridge towards the east. There is a volume of water in the Floridan aquifer that is constantly moving from the west to the east to replenish water that is being withdrawn. Based on the regional movement of the Floridan aquifer and the nature of the Floridan aquifer, the water that is being replenished by the withdrawal is mainly coming from the Floridan aquifer with some contribution from the surficial. Another way to determine the source of the water is by geochemical analysis. The source of the water for this use is characterized as freshwater category number three meaning that it is Floridan aquifer water that is replenishing the water that is being withdrawn and not surface water that is going directly into the Floridan aquifer system. Aquifer Tests The aquifer performance test at the SR 44 wellfield shows that the aquifer is able to produce the volumes of water requested. The depths of the proposed wells, and APT test well, at the SR 44 wellfield is 250 feet below land surface or 150 feet into the Floridan aquifer. The APT at the SR 44 wellfield site provided for the collection of data to show what happens to the water levels while the aquifer is stressed. The second APT at the SR 44 wellfield site tested the Floridan aquifer at a depth of 750 feet below land surface. The section of the Floridan aquifer tested was 500 feet thick. The second APT and geophysical logs showed that there were not any additional flow zones below the upper Floridan aquifer which would yield additional water. Prior to the pump recovery test at the Samsula wellfield, the wells were pumping at 2.59 million gallons per day for a couple of days prior to shutting them off. For a period of five days, four wells in the vicinity of the Samsula wellfield were monitored by the District for water level recovery. The actual observations and the predicted drawdowns in the model correlated well. Drawdown does occur at homeowners' wells when the Commission's Samsula wellfield is pumping, but it does not interfere with existing legal users based on the District rules. The drawdown will not cause a ten percent reduction in the withdrawal capability of the homeowner's well. Computer Modeling The PLASM model simulates the response of the surficial and Floridan aquifers to pumping. The computer model oversimplifies the nature of the surficial aquifer by characterizing the layer as a solid homogeneous type of a system, basically being all sand. In reality, there are some shell and clay layers or hardpan. The transmissivity or the ability to transmit water through the aquifer for surficial aquifer sand ranges between 1,000 up to about 12,000. The transmissivity in the model is 5,000 gallons per day per foot (gpdpf) for Layer 1 which was reasonable. In Layer 2, the data from the APT produced a value of 50,000 gpdpf and a leakance value, or value that would correspond to water that moves from the surficial aquifer down to the Floridan aquifer, of 0.0012 gpdpf. This 50,000 and 0.0012 values are reasonable numbers for this area of Volusia County. The PLASM model is an accepted model for simulating pumpage. In the PLASM model, the transmissivity was varied in two different directions, but it averaged 50,000 gpdpf in the Floridan aquifer system. In the Floridan aquifer system, water is going to be moving based on the transmissivity of the aquifer and a leakance value from the surficial aquifer. The water primarily flows in a horizontal direction. There is a component of vertical movement. The difference between the horizontal movement and the vertical movement is an order of magnitude. There's an order of magnitude difference between the 50,000 gpdpf and the 0.0012 gpdpf which shows that the majority of the water is coming from a horizontal direction. There is some vertical movement. The vertical movement is not only from above, but because of the Floridan aquifer there is also vertical movement from below. When a well is pumping water, the water is being replenished mostly from the horizontal direction and from the lower direction in the same aquifer system, with some contribution downward based on the leakance value from above. This is demonstrated or shown by a small predicted drawdown in the surficial aquifer and that predicted drawdown is basically two orders of magnitude less than the drawdowns in the Floridan aquifer. Proposed Recommended Withdrawal Rates The proposed recommended withdrawal rate from the SR 44 wellfield is 1.43 mgd for average daily flow. With the proposed recommended withdrawal of 1.43 mgd at the SR 44 wellfield, the maximum drawdown in the surficial aquifer is approximately 0.34 feet. With the proposed recommended withdrawal of 1.43 mgd at the SR 44 wellfield, the maximum drawdown in the Floridan aquifer is approximately ten feet. A withdrawal of 1.93 mgd at the SR 44 wellfield site would result in a maximum drawdown in the surficial aquifer of 0.7 feet and in the Floridan aquifer of thirteen (13) feet. The proposed recommended withdrawal rate from the Samsula wellfield is 1.93 mgd for average daily flow. With the proposed recommended withdrawal of 1.93 mgd at the Samsula wellfield, the maximum drawdown in the surficial aquifer is approximately seven tenths (0.70) of a foot. With the proposed recommended withdrawal of 1.93 mgd at the Samsula wellfield, the maximum drawdown in the Floridan aquifer is approximately seventeen (17) feet. The proposed recommended withdrawal rate from the Glencoe wellfield is 1.93 mgd for average daily flow. Under the existing permit, the Samsula wellfield is withdrawing at the higher rate of approximately 2.59 million gallons per day. The volumes of water requested from both the Samsula wellfield and the SR 44 wellfield have been reduced from what was originally proposed by the Commission. The reduced allocation for the Samsula wellfield will improve groundwater elevations and thereby reduce groundwater impacts. Water Quality The state water quality standard for public drinking water is 250 milligrams per liter (mg/l) chlorides. For water supply systems where the chloride level is below 250 mg/l, the District uses that level to determine whether or not the pumping is going to cause significant saline water intrusion. The proposed use cannot cause the water quality to exceed 250 mg/l in chlorides. The water quality data from the existing Samsula and Glencoe wellfields shows that none of the wells or trends from the indicate that they are either above 250 mg/l or trending in a degradation mode toward 250 mg/l. The water quality in the wells is stable without degradation of the water quality in either of the Glencoe wellfield or the Samsula wellfield. The water quality data collected during the APT at the SR 44 wellfield showed that the chlorides were below 250 mg/l and that during the test, there was no change or a trend of becoming salty. An independent study used geophysical methods to determine the depths below land surface where high concentrations of saline water exist. That depth was at approximately 1200 feet below land surface. Proposed Permit Conditions The Commission accepts the conditions of the permit as proposed in the Commission Ex. 10-B. The proposed conditions require the Commission to limit the withdrawals per wellfield as specified and to monitor each production well with a flow meter, monitor the groundwater levels, monitor the surface water conditions, monitor rainfall, and monitor the wetlands. The proposed permit conditions and the County's ombudsman program adequately address the possible impacts of the proposed wellfield on existing users. The monitoring will be able determine the impact of the wellfield on those users. The Commission accepts the condition to mitigate for interference with existing legal users in compliance with the proposed permit conditions. The Volusia County ombudsman program provides the method of investigating and resolving issues related to interference of the proposed wellfield operation with existing legal users. The Commission will participate in this program. The Commission's purchase of the property is contingent upon obtaining the consumptive use permit. The Commission will own the site as shown on various exhibits. The drainage pattern of Tiger Bay is northerly for most of the basin. A canal located north of the area provides the primary drainage for Tiger Bay. A small drainage area within Tiger Bay of approximately 90 acres drains south into the SR 44 wellfield site. Some of the drainage does come through the two 30-inch culverts under SR 44, and both commingle with the wetlands that are on the site as well as drain into a ditch located along the Ranchette Road. The maximum capacity at ideal conditions for those two culverts would be approximately 300 CFS, cubic feet per second. The entire Tiger Bay drainage basin is approximately 13,000 acres. The volume of surface water which can flow from Tiger Bay is 13,000 cfs. That volume could not flow through the culverts at SR 44 without overtopping the road. Ecology The upland communities surrounding the Samsula wellfield are primarily pine flatwoods and mixed pine forested areas. The proposed 1.93 mgd average day withdrawal quantity being recommended by the District for the Samsula wellfield will not adversely affect these upland communities because: (a) the upland communities do not rely on inundated or saturated conditions so the proposed consumptive use will not adversely affect the hydrology these upland communities rely on; and (b) the magnitude of the predicted drawdown will not cause a shift in vegetation meaning a change in the types of plants that already exist there. The wetland communities surrounding the Samsula wellfield site consist of cypress dome and bay swamp communities. With the projected drawdowns information for the Samsula wellfield, there will not be significant adverse impacts to uplands or wetlands that would be identifiable based upon the projected wellfield withdrawal rates as recommended by the District. Any potential for impacts has been reduced in that the current pumpage rates are projected to decrease. The proposed 1.93 mgd average day withdrawal quantity being recommended by the District for the Samsula wellfield will not cause the water table to be lowered such that these wetland communities will be significantly and adversely affected for the following reasons: The wetlands in the area of the Samsula wellfield lie in a sloped terrain. Underlying the site is a soil area known as a spodic horizon or a hardpan layer. The spodic horizon is an area where there is a deposition of organics and it has a different chemistry than the surrounding soils. The spodic horizon, when saturated, acts as a semi-impervious or impermeable layer which causes impedance of water as it goes through. This spodic horizon in the area of the Samsula wellfield is typically two feet below the soil surface. The predicted drawdown will not cause water levels to be dropped such that in normal wet season conditions, which is the time when hydrology to a wetland is most important, the spodic horizon will still be saturated so that water is coming into the wetlands through rainfall directly, as well as rainfall that falls on the adjacent uplands and moves laterally through the soils to the wetland above the spodic horizon. Thus, the spodic horizon will prevent a shift in the "water budget" of these wetlands such that the wetlands will not be harmed by the proposed use. The wetlands systems surrounding the Samsula wellfield are primarily densely forested systems with a fairly substantial accumulation of organic or muck type soils in the surface. The soils assist these wetlands in retaining moisture which provides a "built-in system" for the wetlands to withstand fluctuations in hydroperiods. The wetland systems surrounding the Samsula wellfield appear to have an altered hydrology. The identifiable impacts are ditches or shallow swales along State Road 44. The wetlands south of 44 in the vicinity of wells one, two and three have been bisected by roads and there are swales cut adjacent to those roads. The power line that runs north-south has cut off and eliminated half of a cypress wetland south of 44 and about half of a cypress wetland north of 44. It is possible that these ditches and roads may have caused the altered hydrology in these wetlands. It cannot be concluded that the current Samsula wellfield operation has caused this altered hydroperiod. However, the drawdown that is predicted to occur at the Samsula wellfield under the proposed 1.93 mgd average day withdrawal being recommended by the District is much less than the drawdown that is occurring from the current pumpage at this wellfield. The projected drawdowns from the proposed three wellfield configurations indicate less potential for impacts than the current two wellfields as far as Samsula is concerned. Thus, even if the wetlands surrounding the Samsula wellfield have been affected in any way by the current pumpage rate, the reduced drawdown rates that will result from the 1.93 mgd average day proposed pumpage rate will greatly improve this condition. Other than slight alteration along the edge of SR 44, the wetlands in the vicinity of Samsula wells five and six have not been significantly altered. No changes in vegetation and no apparent changes in hydrology occur in those areas. The cypress wetland north of SR 44 has a drainage ditch emerging to the east. Another wetland immediately north of SR 44, north of well four, is adjacent to the road and the roadside swale or ditch in that vicinity. The species of wildlife identified are ones that are adapted to altered conditions. Abundant wildlife is generally found living in association with improved pastures and close proximity to man. Most of the wetlands in the area of the Samsula wellfield, north and south of SR 44, are in improved pasture or where roads and power lines have been cut. There was evidence of impacts to the wetlands and some drainage. The edge of the cypress dome north of SR 44 has blackberries and other weedy type species along the margins of it. The wetland immediately southeast of well one at the Samsula wellfield was a healthy bay dominated area with ferns underneath. The lichen line on the trunk of the tree and the mosses indicate that the water has been up to or near the historical high within the past season or two. Otherwise, the lichens would grow at the base of the tree. At the Samsula wellfield site, there are no wetlands within the inner drawdown contour of 0.7. There are some wetlands between the 0.7 and the 0.5 contours. The upland communities in the vicinity of the proposed SR 44 wellfield are primarily pine flatwoods and improved pasture. In the pine flatwoods areas, the soils indicate that the water table extends from a height of 0.5 feet below land surface and down to a hardpan layer. The water table in the pine flatwoods fluctuates between the hardpan and 0.5 feet below land surface. The proposed 1.43 mgd average daily withdrawal which is being recommended by the District for the proposed SR 44 wellfield will not significantly and adversely affect these upland communities because these upland communities are not reliant on inundated or saturated conditions, and the proposed consumptive use will not cause a shift in hydrology such that the vegetation found in these communities will no longer be there. The wetland communities in the vicinity of the proposed SR 44 wellfield consist of cypress sloughs and cypress domes which also have herbaceous areas with them. The cypress dominated wetlands are on the northeastern portion of the site and the northwestern portion of the site extending down through the central and southeastern part of the site. Cypress dominated wetlands occur on the southwestern border with one in the east-central portion of the site. Between the cypress dominated wetlands and pine flatwoods are grass prairies. The Commission determined the hydroperiod of the wetlands using vegetative physical evidence or biological indicators, such as lichen lines and mosses, and soil physical evidence from soil probes, which are indicators of long-term and sometimes short-term changes. The wetland on the east-central portion of the proposed SR 44 wellfield site inundates to approximately six and one half inches. In the dry season, the soils dry out to 0.15 feet below land surface. In the wet prairie or wet grassy area, the water table seasonally fluctuates between the hardpan layer of 2.2 feet bls and a tenth or two-tenths of an inch above the surface as based on adventitious roots growing from a St. Johns wort plant species. The water table fluctuations explain the seasonal high and the seasonal low water elevations. The factors which most influence the wetlands and their hydrology are subsurface flow during the wet season, the runoff and direct rainfall. The proposed 1.43 mgd average daily withdrawal for the proposed SR 44 wellfield will not significantly and adversely affect these wetland communities because these wetlands are also underlain by a spodic horizon which, as in the case of the Samsula wellfield wetlands, functions to provide lateral movement of water into the wetlands. The predicted drawdowns for the proposed SR 44 wellfield will not lower the water levels in these wetlands so as to prevent the spodic horizon from performing this function. The recommended withdrawal rate of 1.43 mgd for the proposed SR 44 wellfield reduces the opportunity for impacts. The part of the wellfield site where the greatest drawdown of 0.34 feet occurs is the furthest away from the majority of the wetlands on the site. However, the wetland and soil types on the surface layer are different than the wetland and soil types found at the Samsula wellfield site. The District is recommending a pumpage rate for the proposed SR 44 wellfield that would result in a maximum .34 feet of drawdown in the surficial aquifer while recommending a pumpage rate that would result in a maximum .7 foot drawdown in the surficial aquifer for the Samsula wellfield. The wetlands at the proposed SR 44 wellfield site do not have the dense canopy as well as the accumulation of muck soils in the surface that the wetlands at the Samsula site have. Additionally, the wetlands in the vicinity of the proposed SR 44 wellfield site include herbaceous systems which tend to be shallower systems, not as deeply set as the forested cypress systems are, and therefore tend to be more sensitive to changes that occur in the top couple of inches of soil which is above the spodic horizon. Thus, the wetlands in the vicinity of the proposed SR 44 wellfield would be significantly and adversely affected if the Commission were permitted to withdraw water at a pumpage rate that would result in a drawdown of greater that .34 feet. The drawdowns upon which the evaluation of potential wetland impacts are based are predicted drawdowns. Monitoring and Proposed Conditions To provide additional assurance, the District has recommended a series of permit conditions, numbered 31 through 45 on the Commission Ex. 10-B, that will require the permittee to conduct extensive groundwater and surface water monitoring, as well as vegetative monitoring in the vicinity of the proposed SR 44 wellfield and the Samsula wellfield site. Condition number 31 identifies the overall program of wetland and ground and surface water monitoring. Condition number 32 requires the permittee to install surficial aquifer monitoring wells in the vicinity of the wellfield sites. These monitoring wells will be constructed below the spodic horizon and inside and outside the "area of concern" which is the area within the tenth of a foot drawdown contour at the wellfield sites. This condition will enable the District to analyze how the proposed use is affecting the overall groundwater levels unaffected by the spodic horizon. Placing these wells both inside and outside the area of concern will allow the District to determine if any change in groundwater levels is due to the wellfields or normal climatic patterns. Condition number 33 will allow the District to obtain a constant record of information to analyze what trends are occurring in the wetlands in the wellfields and to have sufficient data during normal climatic variations of the wet and the dry seasons to determine the presence of a trend. The required period of record collection, defined in this condition as the shorter of one calendar year or one consecutive wet to dry season, is a sufficient period of record collection because the purpose of this condition is to obtain a picture in time of the existing conditions in the wetlands surrounding the wellfields during the dry season and the wet season. Condition 33 requires the permittee to submit an annual hydrologic report to the District. This is a sufficient time period of reporting because the purpose of the report is to allow the District to accumulate and assess an entire year's of data or the entire dry to wet season variation. With the annual report, any adverse wetland vegetation changes can be detected prior to any permanent harm to the wetlands. Condition number 34 requires the permittee to install shallow piezometers and staff gauges in the monitored and referenced wetland areas. The monitored wetlands are the wetlands inside the "area of concern." The referenced wetlands are outside the "area of concern." Condition number 34 will allow the District to analyze the hydrology above the spodic horizon. This in turn will allow the District to evaluate the hydrology of the monitored wetlands against the hydrology of the referenced wetlands to determine if any adverse impacts are occurring in the wetlands due to the wellfields' operation. Condition Number 35 requires the permittee to submit surveyed cross- sections of each of the monitored wetlands and the referenced wetlands. This condition will allow the District to receive a linear view of both the monitored and referenced wetlands so that when the District receives the groundwater and surface water information required by condition number 34, it can assign that information to a picture, and know what the wetlands look like under varying water conditions. Condition number 36 requires the permittee to select referenced wetlands similar to the wetlands that are going to be monitored in the area of concern. This will ensure that the reference wetlands match vegetatively and hydrologically with the wetlands that are being monitored within the area of concern. Condition number 37 requires the permittee to install rain gauges at both wellfield sites. This will allow the District to compare rainfall to groundwater information and determine what the relationship is between water levels in the surficial aquifer and the amount of rainfall that has occurred. Condition number 38 requires the permittee to monitor, on a weekly interval, the water levels in each of the monitored wetlands and in the referenced wetlands and submit annual reports of this data. Condition number 39 requires the permittee to install continuous recorders on the staff gauges and piezometers in the reference and monitored wetlands. The information gathered will provide the District with detailed records of the water fluctuations in these wetlands systems relative to rainfall input. Condition number 39 requires the permittee to submit annual reports of the information gathered to the District. The annual report will allow the District to determine if any adverse trends are occurring in the wetlands. No permanent adverse change could occur to the wetlands communities surrounding either wellfield before the District receives this annual report. Condition number 40 requires the permittee to conduct baseline water quality monitoring at each of the monitored wetlands. If any adverse change does occur to the wetlands surrounding either wellfield, and if the permittee chooses to mitigate for this adverse change by augmenting the wetland systems, then this permit condition will allow the District to ensure that the water used to augment those wetlands is of the same quality as the water currently found in those wetlands. Condition number 41 requires the permittee to initiate a baseline vegetative monitoring program of the monitored and reference wetlands at both wellfields. This condition will allow the District to have a vegetative picture of the wetlands prior to any pumpage. Condition number 42 requires the permittee to conduct a vegetative monitoring program of the monitored and reference wetlands at both wellfields with the initiation of withdrawals. Condition number 43 requires the permittee to provide a wetland similarity assessment for both wellfields. The permittee must compare the results of the wetland vegetative monitoring program each year against the baseline vegetative monitoring of the same wetland and against the vegetative monitoring of the referenced wetlands. This condition will assist the District in determining if any adverse trends are occurring in the wetlands surrounding either wellfield. Condition number 44 requires the permittee to create two duplicate reference herbarium collections of the flora present in the monitored and referenced wetlands and the adjacent upland areas. This condition will ensure that there is consistency in the vegetative identification throughout the monitoring program. Condition number 45 requires the permittee to mitigate any harm to the wetlands that is detected from the monitoring required by other permit conditions. This condition does not require any particular form of mitigation. The wellfield withdrawals at the projected rates and the suggested permit rates should not have an impact on threatened or endangered plant or animal species in the Samsula wellfield area or the proposed SR 44 wellfield area. The monitoring program will provide the data to determine on a short- term or long-term basis whether the pumpage rates are causing impacts. Potential harm can be mitigated by adjusting the quantities and locations of withdrawal. V. ATTORNEY'S FEES AND COSTS The Commission seeks fees and costs from Petitioner pursuant to Section 120.59(6), Florida Statutes (1991). Such entitlement requires a showing that the Petitioner brought this case or filed a pleading for an improper purpose. While the evidence does show that certain pleadings filed by Petitioner (or his attorney who withdrew 24 hours prior to the beginning of the hearing) may have had as one purpose the delay of the hearing scheduled for March 24, 1992, the totality of the evidence establishes that Petitioner's purposes were not improper. Section 403.412(5), Florida Statutes (1991), establishes the right of any citizen of the state to intervene into "proceedings for the protection of air, water, or other natural resources of the state from pollution, impairment, or destruction " The actions of Petitioner in this proceeding were not clearly shown to be for delay, harassment or other improper purpose. In fact, Petitioner handled himself well as a pro se litigant after his attorney's untimely withdrawal. If anyone acted with an improper purpose in this proceeding, it was Peter Belmont, Nassau's attorney until he withdrew less than 24 hours prior to the hearing. The record shows that Belmont entered into the representation of Nassau with full knowledge that he would seek all possible delays in the proceedings. He engaged in no preparation for the hearing and he left Nassau unprepared also. Belmont's bad faith actions in this case however can only be determined and remediated by the Florida Bar, not by the undersigned through an award of fees and costs. Finally, there has been no delay in these proceedings. The petition was filed with DOAH on January 16, 1992. The District moved to consolidate it with two other pending case set for January 20, 1992. Those cases were voluntarily dismissed. An Initial Order was sent to the parties on January 21, 1992, seeking suggested dates for the hearing. The hearing was set to begin March 16, 1992, less than 60 days from the filing of the case. A one week continuance was granted and the case was heard beginning on March 24, 1992. If anything, this case has proceeded expeditiously.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that the St. Johns River Water Management District enter a Final Order GRANTING the Utilities Commission of New Smyrna Beach's Consumptive Use Permit, subject to the March 9, 1992 permit conditions proposed by the District (Commission's Exhibit 10-B).

The Issue The issue for consideration at the hearing was whether the Respondent, Roger Harloff, should be issued a consumptive use permit to withdraw and use ground water from the wells on his property, and if so, in what amount and under what conditions.
Findings Of Fact Respondent, Roger Harloff, owns several farms in southeastern Manatee County, Florida which, taken together, make up an irregular 8,500 acre tract located approximately 2 1/2 miles north of the City of Sarasota's Verna Wellfield. Mr. Harloff grows vegetables on much of this tract, of which approximately 1,500 acres is devoted to tomatoes. This tomato crop is the prime crop produced by Mr. Harloff, and provides the raw material for the Harloff packing plant which is dependent upon the tomato crop in order to stay in business. Mr. Harloff also operates a plant nursery at which he produces many if not most of the seedling plants utilized in his vegetable growing operations. In order to be economically feasible and remain operative, Mr. Harloff must farm approximately 3,800 acres during the Spring growing season and approximately 3,000 acres during the Fall. These acres are made up of tomatoes and other vegetables. The packing plant and the plant nursery are dependent upon the farm operation and without adequate water, the farm operation cannot be successfully carried on. In September 1988, Mr. Harloff applied to the District for a consumptive use permit to withdraw water from twelve wells located on his property, requesting an annual average rate of 12,995,606 gpd, and a maximum daily rate of 47,520,000 gpd. The consumptive use permit application filed by Mr. Harloff was assigned District Number 204467.04. After evaluation of the application in conjunction with its needs and policies, the District issued a staff report and proposed agency action on the application which recommended issuance of the permit authorizing water to be drawn from the 12 wells at a rate approximating that requested in the application. Thereafter, the City of Sarasota, which operates the nearby Verna Wellfield, considering that the proposed withdrawal would have a substantial adverse impact on its wellfield operations, filed a Petition for Formal Administrative Hearing objecting to the issuance of the permit to Mr. Harloff. Though Mr. Harloff has owned much of the property which make up the 8,500 acre tract in question here, at the time of his application, he did not own, but had under contract, a substantial portion. He closed on the purchase of that remainder after he received notice of the District's intention to issue the permit in question but prior to the City's filing its Petition For Formal Hearing. The purchase price of the property in question was $9,000,000.00 which carries an interest payment on the financed portion of $52,000.00 per month. The wells pertinent to the issues in this proceeding are as follows: # Cons. Depth Cas. Lin. Diam. Cap. Loc. 1 1978 1185' 200' 220-490' 12" 2000 gpm SE 2. 1988 1320' 210' 210-480' 16" 3000 gpm SE 9. 1974 1130' 390' 16" 3000 gpm C 10. 1976 1232' 231' 283-400' 16" 3000 gpm NW 11. 1979 1120' 210' 260-480' 12" 2000 gpm NW 12. 1976 1180' 480' 12" 2000 gpm SW 3. 1989 1434' 460' 16" 3000 gpm SE 5. 1989 1374' 610' 16" 3000 gpm W 8. 1989 1292' 548' 16" 3000 gpm NW 13. 1989 1310' 635' 16" 2000 gpm NE Well No. 8 was used as the pump test well for the constant rate discharge test and Well No. 13 was the deep observation well for that test. Wells 1, 2, 9, 10, 11, and 12 have all been previously permitted by the District and No's 1, 2, 9 and 10 are currently permitted under two other permits, while 11 and 12 were permitted under a different permit. Wells No. 3, 5, 8 and 13 have been authorized for construction but not, as yet, to produce water. Wells 4, 6 and 7 have not yet been constructed. The intention is to drill them to a depth of 1,300 feet and case them to 600 feet. Each will have a pump capacity of 3,000 gpm. Number 4 will be in the southeast portion of the tract, number 6 in the central portion, and number 7 will be located just north of number 6. Wells 1, 2, 9, and 10 currently have a combined permitted maximum daily rate of 13,680,000 gallons under permits number 204467.03 for 1 and 2, and 204630 for 9 and 10. The former was issued on December 29, 1987 and will expire on December 29, 1993, and the latter, issued on October 7, 1981, will expire on that same day in 1991. The permit previously issued for wells 11 and 12 authorized withdrawal at a maximum daily rate of 2,160,000 gallons. That permit, number 204374, expired on September 9, 1986 and was not renewed. After the City filed its Petition challenging Mr. Harloff's proposed permit, Mr. Harloff, on June 26, 1989, filed an amended application to withdraw water at an average annual rate of 10.99 mgd and a maximum daily rate of 48.96 million gallons. This amended application refers to an additional proposed well, Number 13. The District, however, had previously approved wells 3 - 8 and 13, and pursuant to this authorization, wells 3, 5, 8, and 13 were built. Mr. Harloff submitted additional amendments to his application on August 7 and 9, 1989. The former requests a seasonal average daily rate of 25.34 mgd and a seasonal maximum daily rate of 32.79 mgd. The latter requests a seasonal average rate of 26.18 mgd, an annual average rate of 15.18 mgd, and a seasonal maximum rate of 31.56 mgd. In that regard, a seasonal rate is the same as an annual rate, (average or maximum) when applied to a growing season as opposed to a year. The additional amendments to the application were evaluated by District staff who, on August 18, 1989, issued a revised staff report and a proposal to issue to Mr. Harloff a consumptive use permit authorizing an average annual withdrawal of 11.1. mgd, an average seasonal withdrawal of 15.6 mgd, and a seasonal maximum withdrawal of 20.1 mgd. The proposed permit also contains terms and conditions which, the District contends, will, inter alia, permit Mr. Harloff to withdraw more water than he is currently authorized without additional adverse impact on the City's Verna Wellfield. It is to some of these terms and conditions that Mr. Harloff objects. Since the issuance of the revised staff report and intent to issue, the parties have negotiated on the various terms and conditions in question and have agreed to some and the amendment of others. Mr. Harloff has no objection to conditions number 1, 2, 3, 7 - 14, 23, 24, 26, 28 - 30, 32, and 34 & 35. The parties agree that other conditions, as indicated herein, should be amended as follows: Condition 19, on the third line, should be changed to read, " up to 20 inches tapering to 12 inches." Condition 22, on the second line, should be changed from "30 days" to "10 days". Condition 25, on the first line, should be changed from "within 60 days" to within 120 days". Condition 31, on the third line, starting with "following month" should be changed to "following months: January, April, July and October". Also, under Sampling Frequency, "Monthly" should be changed to "Quarterly". Condition 33, on the ninth line, insert the work "economically" before the word "feasible" in the phrase "specific operation and irrigation improvements are feasible". Mr. Harloff objects to conditions 4, 5, 15 - 17, 20 & 27. He does not object to the proposed new standards for new wells. Taken together, the parties then disagree only on the requirement for abandonment or refurbishment of existing wells and the quantities of water Mr. Harloff will be allowed to draw. The City supports the District's position on both issues. The City of Sarasota owns and operates a public water system to serve between 50 to 75 thousand people located in Sarasota County. The primary source of water for this system is the Verna Well field which is also owned by the City and which accounts for approximately 60 percent of the City's water needs. The City also operates a reverse osmosis, (R.O.) water desalinization facility, and has back-up wells at St. Armond Key and at the Bobby Jones Wellfield. The Verna Wellfield is located about 17 miles east of the Sarasota city limits on approximately 2,000 acres of land in northeastern Sarasota County. It consists of two tracts of land: Part "A", which is approximately 1/2 mile wide by 4 miles long; and Part "B", which is approximately 1 mile square located about 500 feet southeast of Part "A". The Verna Wellfield's permitted allocation is based on whether the R.O. facility is producing at capacity. If it is, the Verna daily allocation is 7 mgd, and if not, 9.5 mgd. The R.O. facility's capacity is 4.5 mgd and the backup wells have a capacity of 1.7 mgd. The wellfield contains 39 permitted production wells, 30 of which are in Part "A" and 9 of which are in Part "B." One of them, well 30, is currently inactive. The wellfield has been in operation as a part of the City's public water system since September 1966. When the Verna Wellfield was constructed in 1965-1966, its original design specified casing on most wells down to 140 feet with pump bowl settings at 125 feet. Each pump was to have a total dynamic head, (TDH) of 200 feet. Over the years, the City has decreased the TDH of the pumps at Verna from 200 feet to 175 feet. This has resulted in a reduction of the pumps' ability to produce water with sufficient pressure to carry it to the discharge point. This decline has been caused by an increase in withdrawal of water regionally, and not solely because of withdrawals from the Verna Well field. Verna is impacted by the use of water outside the boundaries of the wellfield. The City has an ongoing program calling for the refurbishment of 2 to 3 wells per year at the Verna Wellfield. It is the City's intent to convert the pumps to 200 feet TDH on all well refurbishments in the future. In August 1977, a program requiring permits for the consumptive use of water was implemented in both Sarasota and Manatee Counties. At that time, the Verna Wellfield had a production rate of 6.9 mgd annual average daily rate. On January 6, 1978, the City applied for a permit for Verna and on April 3, 1979, the District issued permit number 27804318 to allow the City to draw water from the Verna Wellfield. The City applied for a renewal of that permit in October 1983 and thereafter, in January 1985, the District authorized the continued withdrawal of water from Verna by the issuance of permit 204318 which, at Condition 18, placed limitations on the City's use of water from the wellfield. Specifically, the permit limited withdrawals from Verna to: ...6,000,000 gallons per day average and 7,000,000 gallons per day maximum, except during those times when ... [the R.O. process is reduced or to facilitate maintenance or repairs]. At such times, ... [withdrawals) may be increased to provide additional supplies not to exceed 8,000,000 gallons per day average annual and 9,500,000 gallons per day maximum. This condition clearly provides for additional supplies to be drawn to increase the Verna Well field production to a total of 8,000,000 and 9,500,000 mgd, respectively, not in addition to the regular permitted amount, by those quantities. The City's permit has been neither suspended nor revoked nor is any violation enforcement action currently under way. The current permit expires January 9, 1991. The water pumped from the Verna wells is held in a 1,000,000 gallon reservoir at the wellfield. This reservoir, which is topped at approximately 22 to 23 feet, electronically controls the pumping activity at the well field by turning on and shutting off pumps, in series, as the water level in the reservoir rises and falls. The water, when needed, is transmitted to another reservoir near the City's treatment plant in downtown Sarasota by gravity flow through a 30" diameter, 92,000 foot long pipe. The flow rate is approximately 5,000 gpm normally. When the treatment plant needs more water, a pump at the well field forces the flow at a rate of between 7,200 to 8,200 gpm, depending upon the level of water in the receiving reservoir. A flow of 8,200 gpm would draw 11.8 mgd from the wellfield. The operating capacity of the Verna Wellfield, in August 1988, was 17.9 mgd. Harloff's experts assert, and there is no concrete evidence to rebut it, that if all wells at Verna were pumping during a 24 hour period in May 1989, the reservoir could have been maintained at full level. However, though there is a manual override of the automatic reservoir/pump control system, it is unrealistic and unwise to expect full production on a 24 hour basis for any lengthy time period. Water under both Mr. Harloff's property and the Verna Well field is found at various levels known by different names. These include, in order of descent, the Surficial Aquifer, the Intermediate Aquifer, the Upper Floridan Aquifer, and the Lower Floridan Aquifer. The Surficial Aquifer extends from the surface down to between 20 and 60 feet below the surface. A 20 foot thick bed of clay separates the water in this aquifer from that in the aquifer immediately below it, the Intermediate Aquifer, which extends from approximately 80 feet down to approximately 420 feet below the surface. In the lower part of the Intermediate Aquifer, permeability decreases until a confining unit separating the bottom of the Intermediate Aquifer from the top of the Upper Floridan Aquifer is formed. There is such a confining unit between 420 and 500 feet. There is no well-defined confining unit between the Upper and Lower Floridan Aquifers. There is, however, a substantial difference in the transmissivity in each zone. "Transmissivity" is defined as the amount of water that will exist through a section of the aquifer that is the same width from the top to the bottom. The lower the transmissivity rate, the deeper the cone and the narrower the radius of effect. The higher the rate, the shallower the cone and the broader the radius. The Lower Floridan Aquifer has an extremely high transmissivity. Its top is found at a range of from 1,050 to 1,200 feet below the surface on Mr. Harloff's property. The water from the Upper Floridan Aquifer is of higher quality than that in the Lower. It is more readily usable for drinking than that in the Lower, but the Lower water is quite acceptable for agricultural purposes. What confining layer exists between the Upper and Lower Floridan Aquifers is made up of relatively impermeable anhydrides and gypsum. Because of this, there is little likelihood of the highly mineralized water from the Lower Floridan Aquifer rising into the better quality water in the Upper. If, therefore, water for agricultural purposes is drawn from the Lower Floridan Aquifer, with its high transmissivity and narrower cone radius, and if the wells utilized to procure this water are cased down to within the Lower aquifer, there is little chance of a negative impact on the better quality water, used for drinking by the City, within the Upper Floridan and Intermediate Aquifers. Mr. Hardin, an expert geologist and hydrogeologist testifying for Mr. Harloff, concluded, utilizing certain commonly accepted computer models, that Mr. Harloff's requested additional withdrawals would not have a significant effect on the Verna Wellfield's ability to produce water sufficient for the City's needs. This conclusion was based on 1989 seasonal use figures including an average rate of 21.95 mgd, a maximum rate of 27.04 mgd, and a maximum rate of 29 mgd under a "run time" calculation and the fact that during that period, the City was able to pump at least its permitted quantity from its wells at Verna. The City and the District do not accept this conclusion as reasonable, however, because, they claim, the withdrawal figures cited are not meter readouts but estimates based on the number of acres farmed and the number of pump operating hours during the period in question. The City's experts contend the data used by Hardin and Prochaska in their opinions is not that which other experts in the field would reasonably rely upon. They do not appear to be unrealistic, however, and, therefore, Mr. Hardin's opinion is accepted as but one factor to be considered. On the other hand, Mr. Anderson, also a Harloff expert hydrogeologist, claims the requested withdrawals would result in only an additional 1.7 foot drawdown in the Upper Floridan Aquifer underlying the Northeast corner of the Verna Well field. To be sure, this is only one small portion of the wellfield in issue. There has, however, been a continuing history of declining groundwater levels in this area over the past several years. After the 1975 drought, the City started to experience declining water levels at Verna which, because of the reduction in ability to produce water, required a lowering of the pump elements in some wells, and also caused the City to develop an R.O. facility in an effort to reduce dependence on well water. This drop in capability occurred again during the 1985 drought and this time the City modified the pump motors to shut off prior to cavitation and initiated a schedule of operating times for wells, so that water is drawn from different and geographically separated areas in a sequence designed to allow periodic regeneration of an area's supply. Nevertheless, water supply remains a concern at Verna, and the problems previously experienced continue to occur during periods of drought. In May 1989, the Verna Wellfield was periodically "unable" to meet it's short term peak demands at times even though all operating wells were pumping. This means that at the times in question, more water was being drawn from the Verna reservoir than could be replaced by pumping activities. It does not mean that the reservoir ran dry and water could not be furnished to the treatment plant. However, this condition is serious and indicative of a more serious shortage in the future unless appropriate safeguards are instituted. Mr. Balleau, the City's expert in hydrology and hydrogeology, and the District's experts all believe the Verna Wellfield is in trouble. It is operating well beyond its design range and the imposition of additional demands on it would seriously and adversely affect its ability to produce water. This position is supported by the facts and found to be accurate. There appear to be several options open to the City to contend with the Verna problem potential. These include: drill deeper wells at Verna to tap the Lower Floridan Aquifer. (This will produce the lower quality water found there and require additional treatment facilities. construct a linear wellfield along the pipeline from Verna to the treatment facility. (This will require additional permitting to draw the water, high construction and operating costs, and still result in low quality water requiring treatment. redevelop the downtown wells currently supplying the R.O. facility. (This will require satisfaction of regulatory issues, adversely impact on the users of the upper aquifers, possibly result in poor water quality and in contamination from nearby landfills.) develop a new well field southeast of Verna. (This will experience regulatory issues and high construction costs, with an unknown water quality result.) buy water from Manatee County. (This is expensive, may result in transmission and compatibility problems, and would be only a short term solution. lower pump assemblies; replace existing pumps and modify the pump circuits. (These are all unreliable, short term solutions of minimal benefit.) Mr. Harloff and the City/District disagree on the appropriate amount of water needed for the successful growing of the crops produced by his operations. Both agree, however, that the heaviest demands for water come in the spring growing season including April and May. Tomatoes require the most water. Peppers require nearly as much. This is because the short root systems require a higher water table in the soil to supply needed moisture. In its analysis of Mr. Harloff's application, the District, referring to tables developed for the purpose of allocation and relating to Harloff's watering history during the period from August 15, 1988 to June 7, 1989, subtracted the fall season recorded application of 20.7 acre-inches from the total 10 month figure of 50.92 acre-inches and concluded he would need 30.22 acre-inches for peppers during the spring, 1989 season. Unless shown to be totally unreasonable, however, (not the case here), the applicant's water need figures should be accepted. Mr. Harloff's operation constitutes an important part of Manatee County's agricultural economy, and agriculture utilizes 68.9 percent of the land in the county. Agricultural products sold in Manatee County in 1987 were valued at $145,655,000.00, which ranked Manatee County third among all Florida counties in vegetable production. Agriculture is the fourth largest employer in Manatee County, employing an average of 4,692 people per month. Through his farm operation alone, Harloff employes as many as 1,050 people, with 200 employed on a full-time basis. Experts estimate that the loss of the Harloff operation would cause a reduction of between 16 and 18 million dollars in agricultural sales in the county with an additional loss in jobs and income to his suppliers. This estimate is not at all unreasonable. Florida produces approximately 95 percent of all tomatoes grown in this country for the fresh tomato market during the winter growing season. Tomatoes are the single largest vegetable crop grown in the state and accounted for 39.7 percent of the total value of vegetables produced in Florida during the 1987-1988 growing season. Mr. Harloff produced 4.8 percent of the total shipment of tomatoes from this state during that period. Water, primarily through irrigation, is an indispensable portion of the farming operation for this crop. Mr. Harloff currently irrigates the majority of his non-citrus crops by use of a "semi-closed ditch irrigation system", as opposed to a "drip system." The drip system is considerably more efficient than the semi-closed system having an efficiency rating, (amount of water actually used by the plants) of between 80 to 90 percent, as opposed to 40 to 60 percent for the other. While Mr. Harloff could reduce his water needs considerably and achieve substantial savings on pump fuel by conversion to a drip system for all or a part of his crops, such an undertaking would be quite costly. One of the conditions proposed by the District for the approval of Harloff's permit, as amended, is the refurbishment of several of the existing wells utilized by Mr. Harloff to make them more efficient and to promote the withdrawal of water from the Lower Floridan Aquifer, in which there appears to be adequate water and from which the Verna Well field does not draw. Currently, Mr. Harloff has seven wells which do not meet the standards of this proposed condition. They are not drilled to 1,300 feet below mean sea level and are not cased to 600 feet. To bring these wells into compliance, they would have to be drilled to the 1,300 foot level, or to a level which has a specific capacity of 400 gpm, and the casings in each would have to be extended to 600 feet. Extending the casings would be a complicated procedure and Harloff's experts in the area cannot guarantee the procedure would successfully achieve the desired end. Assuming the retrofit was successful, the cost of the entire process would be approximately $15,000.00 to $16,000.00 per well. In addition, the process would, perforce, require reducing the diameter of the well from 10 to 8 inches, thereby necessitating increasing the pump capacity to produce sufficient water. The cost of this is substantial with an appropriate new pump costing somewhere between $10,000.00 and $15,000.00 each. Consequently, the anticipated cost of bringing the existing wells up to condition standards would be between $25,000.00 to $31,000.00 per well, while the cost of constructing a new well is between $40,000.00 and $50,000.00 per well. Mr. Harloff feels it would be more prudent for him to replace the existing wells rather than to retrofit them. This may be correct. Harloff experts also claim that extending the casings on the existing wells down to 600 feet would not provide a significant benefit to the aquifer nor cause any significant reduction in drawdown impact at Verna. The District and City experts disagree and, taken on balance, caution and the interests of the public indicate that a conservative approach is more appropriate. While Mr. Harloff proposes to convert the areas served by wells 1, 9, 11, and 12 to the growing of citrus which requires much less water than tomatoes, this would not be sufficient mitigation to offset the need for some modification if large amounts of water will still be drawn. The entire area under the District's jurisdiction has been experiencing a water shortage due to a lack of rainfall. As a result, in June 1989, the District adopted a resolution identifying an area, including the area in question here, as a "water use caution area." This was done because the Floridan Aquifer has been subjected to large seasonable drawdowns of the potientiometric surface, the level to which water in a confined aquifer can rise in a well which penetrates that acquifer. This drawdown is directly related to increased water use in the area, much of which is for agricultural purposes. As a result of the District's action, special conditions on well construction for consumptive use applicants have been imposed on a permit by permit basis to insure, as much as possible, that the applicant uses the lowest quality water appropriate for his intended purpose. These conditions are not unreasonable. While accepting the District's and City's conclusion that his wells, if permitted, would have some impact on the Verna Wellfield, Mr. Harloff does not concede that the impact is significant. Specifically, the difference in impact resulting from an increase from his currently permitted use of 13.68 mgd seasonal maximum and his requested use of 31.56 mgd seasonal maximum for wells 1, 2, 9, and 10 would be a maximum increased drawdown of 1.1 feet at the Intermediate aquifer and 1.8 feet at the Upper Floridan Aquifer. Both figures relate to that portion of the wellfield found in the northeast corner of Part A. If the anticipated usage for crops predicted by Mr. Harloff's experts for the spring of 1989 is accurate, the drawdown would be 0.2 feet for the intermediate aquifer and 0.4 feet for the Upper Floridan Aquifer measured at the northeast corner of Part B of the Verna We1lfield. Harloff's experts contend that additional impacts for the spring of 1989 included, the increased usage will not have a significant effect on Verna's ability to produce its permitted daily maximum withdrawal of 9.5 mgd. While this is an educated speculation, it should be noted that during May 1989, the Verna field was able to produce up to 8.3 mgd without using all wells during any 24 hour period. This does not consider, however, the problems encountered by the City as indicated by the wellfield personnel, and the fact that some of the City wells are not pumping water.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: RECOMMENDED that Roger Harloff be issued a consumptive use permit, No. 204467.04, as modified, to reflect authorization to draw 15.18 mgd annual average, not to exceed 31.56 mgd seasonal maximum, conditioned upon compliance with the conditions found in the conditions portion of the permit, as modified to conform to the quantities as stated herein, and to include those requirements as to acre-inch and crop-acre limitations, well usage and abandonment schedules, well modification standards, and record keeping, as are contained therein. RECOMMENDED this 5th day of December, 1989, in Tallahassee, Florida. ARNOLD H.
