The Issue Whether proposed Water Use Permits Nos. 20012236.000 (the Potable Water Permit) and 20012239.000 (the Irrigation Permit) and proposed Environmental Resource Permit No. 43020198.001 (the ERP) should be issued by the Respondent, Southwest Florida Water Management District (the District).
Findings Of Fact The Parties The individual Petitioners, Farnsworth, Roop, and Varnum are all Florida citizens and residents of Sumter County. None of the individual Petitioners offered any evidence relating to direct impacts that the ERP would have on their property. With respect to the Potable Water and Irrigation Permits, anecdotal testimony was presented by Petitioners and Wing and Weir relating to well failures and sinkholes in the area. Two Petitioners, Roop and Varnum, live in close proximity to the property encompassed by the three permits. Petitioner Farnsworth’s property is approximately three and a half miles from the project boundary. Wing and Weir live approximately four and a half to five and 18 miles from the project site, respectively. SCAID is a Florida not-for-profit corporation that has approximately 130 members. Farnsworth, the president of SCAID, identified only Roop and Varnum as members who will be directly affected by the activities to be authorized by the permits. The District is the administrative agency charged with the responsibility to conserve, protect, manage, and control water resources within its boundaries. The Utility and the Authority are limited liability companies, of which the Villages Inc. is the managing partner. The Villages Inc. is a Florida corporation. The Utility, which will serve as a provider of potable water, is regulated by the Public Service Commission, while the Authority which will provide irrigation water, is not. The Villages Inc., Development The Villages Inc. is a phased, mixed use, retirement community, which is located at the intersecting borders of Lake, Marion, and Sumter Counties. Development has been on going since at least 1983, with a current planning horizon of the year 2019. Currently, there are 15,362 constructed dwelling units in the built-out portion of the Villages Inc. that are located in Lake County and the extreme northeast corner of Sumter County. The portion located in Marion County is 60 percent complete, with 750 homes completed and another 600 under construction. Approximately another 22,000 residences are planned for development in Sumter County by the year 2012, with an additional 10,200 by the year 2019. However, the Potable Water and Irrigation Permits are only for a six-year duration, and the ERP has a duration of only six years. None of the permits authorize development activities beyond that time frame. Generally speaking, the three permits at issue include an area owned by the Villages Inc. that lies in northeast Sumter County South of County Road 466 and North of County Road 466A. However, it is not projected that this entire area will be built-out during the terms of three proposed permits. Area Hydrology and Topography In the area of the Villages Inc., there is a layer of approximately five to ten feet of sand at the land surface, which is underlain by ten to 70 feet of a clayey sand. Both of these constitute the surficial aquifer and are extremely leaky, allowing water to percolate easily through to a lower layer. Except in the vicinity of Lake Miona, there is no water in the surficial aquifer except after rainfall events. The clayey sand layer is underlain by the Upper Floridan, a limestone unit. The top of this limestone layer ("the top of the rock") occurs at fluctuating depths of between 30 and 70 feet. At approximately 350 to 400 feet below the land surface, there begins a transition to a denser unit that serves as a confining layer between the Upper Floridan production zone and the Lower Floridan production zone. This confining layer, which was confirmed by drilling at three locations in the Villages Inc. is approximately 150 feet thick in the area of the Villages Inc. Another transition, this time to a less dense formation, begins at approximately 550 to 600 feet, which is considered the top of the Lower Floridan production zone. While testing conducted on the project site indicated almost no leakage between the Upper and Lower Floridan production zones, it is generally known by experts that there is some exchange of water between the two layers. Both the Upper and the Lower Floridan contain water that meets potable water standards and both are considered water production zones. The water quality of the two zones is not significantly different. The project area is prone to karst activity, that is, the formation of sinkholes. Sinkholes are formed as a result of the collapse of the overburden above subsurface cavities which have been formed through a very gradual dissolution of limestone, thus resulting in a "sink" at the land surface. Surface water bodies in the area include Lake Miona, Black Lake, Cherry Lake, and Dry Prairie, as well as several other small wetlands. The Potable Water and Irrigation Permits The potable water permit is for the withdrawal from the Upper Floridan Aquifer of 1.164 million gallons of water per day (MGD), on an annual average, for potable use in residences and both commercial and recreational establishments. It also limits the maximum withdrawal during peak months to 2.909 MGD. The Irrigation Permit is for the withdrawal from the Lower Floridan Aquifer of 2.850 MGD, on an annual average, for use in irrigation. The peak month usage rate permissible under the proposed permit would be 9.090 MGD. Water withdrawal under the Irrigation Permit will be used for the irrigation of residential lawns, common areas, commercial landscaping, and golf courses. Modeling of Drawdowns In assessing the impacts of proposed water withdrawals from an aquifer, District personnel considered effects on the aquifers and on-surface water features in the area. Computer- generated models of the predicted effects of the Potable Water and Irrigation Permits withdrawals provided one of the principal bases for this assessment. The primary geologist assigned to review the permit applications reviewed two of the models submitted by the Utility and the Authority (jointly the WUP Applicants) and ran one personal model of her own in order to predict the effects of the proposed withdrawals on the aquifers, as well as on any wetlands and other surface water bodies. In particular, the models predict both the vertical and horizontal extent to which the withdrawals may lower the level of water within the aquifers and in-surface waters under various conditions. One of the models submitted by the WUP Applicants predicted drawdowns during a 90-day period of no rainfall while the other predicted the impacts of the withdrawals over the life of the permits, considered cumulatively with the effects of withdrawals from the already-existing Villages' development in Sumter, Marion, and Lake Counties. The District’s geologist modeled the impacts of the withdrawals over the life of the permits and included the cumulative effects of all of the current Villages' withdrawals in Sumter County. All of these models included the combined effects of both the proposed Potable Water and the Irrigation Permits. Based upon these models, it is concluded that there will be no significant drawdowns as a result of the withdrawals authorized by the proposed water use permits. Specifically, the only predicted drawdown in the surficial aquifer (0.25 feet of drawdown) is in an area where there are no natural surface water features. Drawdown in the Upper Floridan is predicted at between 0.1 and 0.2 feet, while the drawdown in the Lower Floridan is predicted at a maximum of 1.5 feet. These minor drawdowns are not expected to cause any adverse impacts. Transmissivity is the rate at which water moves horizontally through the aquifer. In areas with high transmissivity, the results of water withdrawals from an aquifer will generally be low in magnitude, but broad in lateral extent. Water withdrawals from areas of low transmissivity will result in cones of depression that are more limited in lateral extent, but steeper vertically. The use of too high a transmissivity rate in a model, would overpredict the horizontal distance of the drawdowns caused by withdrawals, but would underpredict the vertical drawdown in the immediate vicinity of the withdrawal. Conversely, use of too low a transmissivity would over-predict the effects in the immediate vicinity of the withdrawal but underpredict the lateral extent of the drawdown. The WUP Applicants’ models used a transmissivity value for the Lower Floridan Aquifer of 100,000 feet squared per day ("ft.2/d'). The WUP Applicants’ consultant derived the transmissivity values from a regional model prepared by the University of Florida. The regional model uses a transmissivity value for the entire region of 200,000 ft.2/d for the Lower Floridan. While that transmissivity is appropriate for assessing large-scale impacts, on a more localized level, the transmissivity of the aquifer may be lower. Therefore, the WUP Applicants’ consultant met with District representatives and agreed to use a value half that used in the University of Florida model. A similar approach was used for the transmissivity value used in modeling effects in the Upper Floridan. Notably, specific transmissivity values recorded in four wells in the Villages Inc. area were not used because two of these wells were only cased to a depth of just over 250 feet, with an open hole below that to a depth of 590 feet. Thus, the transmissivity measured in these wells reflect conditions in the confining layer at the immediate location of the wells - not the transmissivity of the Lower Floridan production zone. Further, site-specific information on transmissivity, measured during pump tests at individual wells, does not correlate well to the transmissivity of the aquifer, even at short distances from the well. Transmissivities measured at individual wells are used to determine the depth at which the pump should be set in the well, not to determine the transmissivity of the aquifer. Thus, the use of transmissivities derived from the regional model, but adjusted to be conservative, is entirely appropriate. Moreover, using a transmissivity in her modeling of the project impacts of 27,000 ft.2/d for the Lower Floridan Aquifer, the district geologist’s model predicted no adverse impacts. Leakance is the measure of the resistance of movement vertically through confining units of the aquifer. The leakance value used by the District for the confining layer between the Upper and Lower Floridan was taken from the University of Florida model. Tests conducted on the site actually measured even lower leakance values. Thus, the evidence establishes that the leakance value used in the WUP Applicants’ and the District’s modeling for the Floridan confining layer was reasonable and appropriate. Competent, substantial evidence also establishes that the leakance value used for Lake Miona was reasonable. The WUP Applicants submitted to the District substantial data, gathered over several years, reflecting the balance of water flowing into Lake Miona and the lake’s levels in relation to the potentiometric surface. This documentation verified the leakance value used for Lake Miona in the modeling. Finally, the District modeling used appropriate boundary condition parameters. The District modeling used what is known as the "constant head" boundary and assumes the existence of water generated off-site at the boundaries. Such a boundary simulates the discharge of the aquifer at a certain level. The use of constant head boundaries is an accepted practice. The modeling conducted on behalf of the District and the Applicants provides a reasonable assurances that the Potable Water and Irrigation Permits will not cause adverse water quality or quantity changes to surface or groundwater resources, will not cause adverse environmental impacts to natural resources, and will not cause pollution of the aquifer. Furthermore, because the predicted drawdowns are so insignificant, reasonable assurances have been provided that the withdrawals will not adversely impact existing off-site land uses or existing legal withdrawals. The modeling also provides reasonable assurances that the withdrawals will not be harmful to the water resources of the District. Moreover, monitoring requirements included in the proposed Potable Water and Irrigation Permits provide additional reasonable assurance that – should the withdrawal effects exceed those predicted by the modeling – such effects are identified and necessary steps are taken to mitigate for any potential impacts. The District has reserved the right to modify or revoke all or portions of the water use permits under certain circumstances. Specifically, the proposed Potable Water Permit requires a monitoring plan that includes the following pertinent provisions: There shall be no less than three control wetland and ten onsite wetland monitoring sites; A baseline monitoring report, outlining the current wetland conditions; * * * A statement indicating that an analysis of the water level records for area lakes, including Miona Lake, Black Lake, Cherry Lake, Lake Deaton and Lake Griffin, will be included in the annual report; A statement indicating that an analysis of the spring flow records for Gum Spring, Silver Spring, and Fenney Spring, will be included in the annual report; * * * Wildlife analyses for potentially impacted wetlands, lakes, and adjacent property owner uses or wells, including methods to determine success of the mitigation; A mitigation plan for potentially impacted wetlands, lakes, and adjacent property owner uses or wells, including methods and thresholds to determine success of the mitigation; An annual report of an analysis of the monitoring data . . . . Similar provisions are included in the proposed irrigation permit. The WUP Applicants, in conjunction with the District, have developed sites and methodologies for this monitoring. Reasonable Demand The water to be withdrawn under the proposed Potable Water Permit will serve 10,783 people. This total results from the simple multiplication of the number of residences to be built during the next six years (5,675) by the average number of residents per household (1.9). Those numbers are based upon historical absorption rates within the Villages Inc. development since 1983, an absorption rate that doubles approximately every five years. The Utility proposed a per capita use rate of 108 gallons per day for potable use only. District personnel independently verified that per capita rate, based upon current usage in the existing portions of the Villages Inc. and determined that the rate was reasonable. Based upon the population projections and the per capita rate, the District determined that there is a reasonable demand for the withdrawal of the amount of water, for potable purposes, that is reflected in the Potable Water Permit. The Utility has provided reasonable assurance regarding the Utility’s satisfaction of this permitting criterion. As to the irrigation permit, the Villages Inc. plans, within the next six years, to complete the construction of 1,911 acres of property that will require irrigation. The amount of water originally requested by the Authority for irrigation withdrawals was reduced during the course of the application process at the request of the District. The District determined the reasonable amount of irrigation water needed through the application of AGMOD, a computer model that predicts the irrigation needs of various vegetative covers. Since the Authority intends to utilize treated wastewater effluent as another source of irrigation water, the District reduced the amount of water that it would permit to be withdrawn from the Lower Floridan for irrigation. The District, thus, determined that the Authority would need 1.59 MGD annual average for recreational and aesthetic area irrigation and 1.26 MGD annual average for residential lawn irrigation, for a total of 2.85 MGD. The Villages Inc. also plans to accumulate stormwater in lined ponds for irrigation use. However, unlike its treatment of wastewater effluent, the District did not deduct accumulated stormwater from the amount of water deemed necessary for irrigation. This approach was adopted due to the inability to predict short-term rainfall amounts. The uncontroverted evidence of record establishes reasonable assurances that there is a reasonable demand for the amount of water to be withdrawn under the proposed irrigation permit. Conservation and Reuse Measures Both the Utility and the Authority applications included proposed measures for the conservation and reuse of water. The conservation plan submitted in conjunction with the irrigation permit application provides for control valves to regulate both the pressure and timing of irrigation by residential users; contractual restrictions on water use by commercial users; xeriscaping; and an irrigation control system for golf course irrigation that is designed to maximize the efficient use of water. In addition, in the proposed permits, the District requires the Utility and the Authority to expand upon these conservation measures through such measures as educational efforts, inclined block rate structures, and annual reporting to assess the success of conservation measures. The Authority also committed to reduce its dependence on groundwater withdrawals through the reuse of wastewater effluent, both from the on-site wastewater treatment facility and through contract with the City of Wildwood. Reasonable assurances have been provided that conservation measures have been incorporated and that, to the maximum extent practicable, reuse measures have been incorporated. Use of Lowest Available Quality of Water In addition to the reuse of treated wastewater effluent, the Authority intends to minimize its dependence on groundwater withdrawals for irrigation use through the reuse of stormwater accumulated in lined ponds. Thirty-one of the lined stormwater retention ponds to be constructed by the Villages Inc. are designed as a component of the irrigation system on-site. Ponds will be grouped with the individual ponds within each group linked through underground piping. There will be an electronically controlled valve in the stormwater pond at the end of the pipe that will be used to draw out water for irrigation purposes. These lined stormwater ponds serve several purposes. However, the design feature that is pertinent to the reuse of stormwater for irrigation is the inclusion of additional storage capacity below the top of the pond liner. No groundwater will be withdrawn for irrigation purposes unless the level of stormwater in these lined ponds drops below a designed minimum irrigation level. Groundwater pumped into these ponds will then be pumped out for irrigation. Thus, the use of groundwater for irrigation is minimized. The Authority has met its burden of proving that it will use the lowest quality of water available. With respect to the potable permit, the evidence establishes that there are only minor differences between the water quality in the Upper Floridan and Lower Floridan in this area. The Upper Floridan is a reasonable source for potable supply in this area. Thus, reasonable assurances have been provided by the Utility that it will utilize the lowest water quality that it has the ability to use for potable purposes. Waste of Water In regard to concerns that the design of the Villages Inc.'s stormwater/irrigation system will result in wasteful losses of water due to evaporation from the surface of the lined ponds, it must be noted that there are no artesian wells relating to this project and nothing in the record to suggest that the groundwater withdrawals by either the Utility or the Authority will cause excess water to run into the surface water system. Additionally, the evidence establishes that, to the extent groundwater will be withdrawn from the Lower Floridan and pumped into lined stormwater ponds, such augmentation is not for an aesthetic purpose. Instead, the groundwater added to those ponds will be utilized as an integral part of the irrigation system and will be limited in quantity to the amount necessary for immediate irrigation needs. Finally, the water to be withdrawn will be put to beneficial potable and irrigation uses, rather than wasteful purposes. Under current regulation, water lost from lined stormwater ponds through evaporation is not considered as waste. Thus, the Authority and the Utility have provided reasonable assurances that their withdrawals of groundwater will not result in waste. The ERP The stormwater management system proposed by the Villages Inc. will eventually serve 5,016 acres on which residential, commercial, golf course, and other recreational development will ultimately be constructed. However, the proposed permit currently at issue is preliminary in nature and will only authorize the construction of stormwater ponds, earthworks relating to the construction of compensating flood storage, and wetland mitigation. Water Quality Impacts The stormwater management system will include eight shallow treatment ponds that will be adjacent to Lake Miona and Black Lake and 45 lined retention ponds. Thirty-one of these lined ponds will serve as part of the irrigation system for a portion of the Villages Inc.'s development. All of these ponds provide water quality treatment. The unlined ponds will retain the first one inch of stormwater and then overflow into the lakes. The ponds provide water quality treatment of such water before it is discharged into the lakes. The water quality treatment provided by these ponds provides reasonable assurances that the project will not adversely impact the water quality of receiving waters. While they do not discharge directly to surface receiving waters, the lined retention ponds do provide protection against adverse water quality impacts on groundwater. There will be some percolation from these ponds, from the sides at heights above the top of the liner. However, the liners will prevent the discharge of pollutants through the highly permeable surface strata into the groundwater. The Villages Inc. designed the system in this manner in response to concerns voiced by the Department of Environmental Protection during the DRI process regarding potential pollutant loading of the aquifer at the retention pond sites. Furthermore, by distributing the accumulated stormwater - through the irrigation system - over a wider expanse of vegetated land surface, a greater degree of water quality treatment will be achieved than if the stormwater were simply permitted to percolate directly through the pond bottom. There is no reasonable expectation that pollutants will be discharged into the aquifer from the lined ponds. If dry ponds were used, there would be an accumulation of pollutants in the pond bottom. These measures provide reasonable assurances that there will be no adverse impact on the quality of receiving waters. Water Quantity Impacts With regard to the use of lined retention ponds, as part of the Villages Inc.’s stormwater system and the impact of such ponds on water quantity, the evaporative losses from lined ponds as opposed to unlined ponds is a differential of approximately one (1) inch of net recharge. The acreage of the lined ponds - even measured at the very top of the pond banks - is only 445 acres. That differential, in terms of a gross water balance, is not significant, in view of the other benefits provided by the lined ponds. As part of the project, wetlands will be created and expanded and other water bodies will be created. After rainfalls, these unlined ponds will be filled with water and will lose as much water through evaporation as would any other water body. The design proposed by the Villages Inc., however, will distribute the accumulated stormwater across the project site through the irrigation of vegetated areas. The documentation submitted by the Villages Inc. establishes that the ERP will not cause adverse water quantity impacts. The Villages Inc. has carried its burden as to this permitting criterion. Flooding, Surface Water Conveyance, and Storage Impacts Parts of the project are located in areas designated by the Federal Emergency Management Administration (FEMA) as 100-year flood zones. Specifically, these areas are located along Lake Miona, Black Lake, between Black Lake and Cherry Lake, and at some locations south of Black Lake. Under the District’s rules, compensation must be provided for any loss of flood zone in filled areas by the excavation of other areas. The District has determined, based upon the documentation provided with the Villages Inc.’s application, work on the site will encroach on 871.37 acre feet of the FEMA 100-year flood zone. However, 1,051.70 acre feet of compensating flood zone is being created. The Villages Inc. proposes to mitigate for the loss of flood zone primarily in the areas of Dry Prairie and Cherry Lake. At present, Cherry Lake is the location of a peat mining operation authorized by DEP permit. Mining has occurred at that site since the early 1980s. The flood zone mitigation proposed by the Villages Inc. provides reasonable assurance that it will sufficiently compensate for any loss of flood basin storage. The Villages Inc.'s project provides reasonable assurance that it will neither adversely affect surface water storage or conveyance capabilities, surface or groundwater levels or surface water flows nor cause adverse flooding. Each of the 45 retention ponds to be constructed on-site will include sufficient capacity, above the top of the pond liner, to hold a 100-year/24-hour storm event. This includes stormwater drainage from off-site. In addition, these ponds are designed to have an extra one foot of freeboard above that needed for the 100-year/24-hour storm, thus providing approximately an additional 100 acres of flood storage beyond that which will be lost through construction on-site. Furthermore, the Villages Inc. has proposed an emergency flood plan. In the event of a severe flood event, excess water will be pumped from Dry Prairie, Cherry Lake, and Lake Miona and delivered to the retention ponds and to certain golf course fairways located such that habitable living spaces would not be endangered. Environmental Impacts and Mitigation There are 601 acres of wetlands and surface waters of various kinds in the Villages Inc.’s project area. Forty-one acres of wetlands will be impacted by the work that is authorized under the ERP. Each of these impacted wetlands, along with the extent of the impact, is listed in the ERP. The impacts include both fill and excavation and all will be permanent. When assessing wetland impacts and proposed mitigation for those impacts, the District seeks to ensure that the activities proposed will not result in a net loss of wetland functionality. The object is to ensure that the end result will function at least as well as did the wetlands in their pre-impact condition. Functional value is judged, at least in part, by the long term viability of the wetland. While small, isolated wetlands are not completely without value, large wetland ecosystems – which are less susceptible to surrounding development – generally have greater long-term habitat value. The District’s policy is that an applicant need not provide any mitigation for the loss of habitat in wetlands of less than 0.5 acre, except under certain limited circumstances, including where the wetland is utilized by threatened or endangered species. Some wetlands that will be impacted by the Villages Inc.’s project are of high functional value and some are not as good. The Villages Inc. proposes a variety of types of mitigation for the wetlands impacts that will result from its project, all of which are summarized in the ERP. In all, 331.55 acres of mitigation are proposed by the Villages Inc. First, the District proposes to create new wetlands. Approximately 11 acres of this new wetland will consist of a marsh, which is to be created east of Cherry Lake. Second, it proposes to undertake substantial enhancement of Dry Prairie, a 126-acre wetland. Currently – and since at least the early nineties – Dry Prairie received discharge water from the peat mining operation at Cherry Lake. Without intervention, when the mining operations stop, Dry Prairie would naturally become drier than it has been for several years and would lose some of the habitat function that it has been providing. The Villages Inc.’s proposed enhancement is designed to match the current hydroperiods of Dry Prairie, thus ensuring its continued habitat value. Third, the Villages Inc. has proposed to enhance upland buffers around wetlands and surface waters by planting natural vegetation, thus providing a natural barrier. Placement of these buffers in conservation easements does not provide the Villages Inc. with mitigation credit, since a 25-foot buffer is required anyway. However, the District determined that the enhancement of these areas provided functional value to the wetlands and surface waters that would not be served by the easements alone. Fourth, the Villages Inc. will place a conservation easement over certain areas, including a 1500-foot radius preserve required by the Fish and Wildlife Conservation Commission (FWCC) around an identified eagles’ nest. These areas will also be used for the relocation of gopher tortoises and, if any are subsequently located, of gopher frogs. While the Villages Inc. is also performing some enhancement of this area, it will receive no mitigation credit for such enhancement – which was required to meet FWCC requirements. However, since the conservation easement will remain in effect in perpetuity, regardless of whether the eagles continue to use the nest, the easement ensures the continued, viability of the area’s wetlands and provides threatened and endangered species habitat. In order to provide additional assurances that these mitigation efforts will be successful, the District has included a condition in the proposed permit establishing wetland mitigation success criteria for the various types of proposed mitigation. If these success criteria are not achieved, additional mitigation must be provided. With the above described mitigation, the activities authorized under the ERP will not adversely impact the functional value of wetlands and other surface waters to fish or wildlife. The Villages Inc. has met its burden of providing reasonable assurances relating to this permit criterion. Capability of Performing Effectively The Villages Inc. has also provided reasonable assurances that the stormwater management system proposed is capable of functioning as designed. The retention ponds proposed are generally of a standard-type design and will not require complicated maintenance procedures. In its assessment of the functional capability of the system, the District did not concern itself with the amount of stormwater that the system might contribute for irrigation purposes. Rather, it focused its consideration on the stormwater management functions of the system. The question of the effectiveness of the system for irrigation purposes is not relevant to the determination of whether the Villages Inc. has met the criteria for permit issuance. Consequently, the record establishes that the documentation provided by the Villages Inc. contains reasonable assurances that the stormwater system will function effectively and as proposed. Operation Entity The Villages Inc. has created Community Development District No. 5 (CDD No. 5), which will serve as the entity responsible for the construction and maintenance of the stormwater system. CDD No. 5 will finance the construction through special revenue assessment bonds and will finance maintenance through the annual assessments. Similar community development districts were established to be responsible for earlier phases of the Villages Inc. The ERP includes a specific condition that, prior to any wetlands impacts, the Villages Inc. will either have to provide the District with documentation of the creation of a community development district or present the District with a performance bond in the amount of $1,698,696.00. Since the undisputed testimony at hearing was that CDD No. 5 has, in fact, now been created, there are reasonable assurances of financial responsibility. Secondary and Cumulative Impacts The Villages Inc.’s application also provides accurate and reliable information sufficient to establish that there are reasonable assurances that the proposed stormwater system will not cause unacceptable cumulative impacts upon wetlands or other surface waters or adverse secondary impacts to water resources. The system is designed in a manner that will meet water treatment criteria and there will be no secondary water quality impacts. Further, the use of buffers will prevent secondary impacts to wetlands and wetland habitats and there will be no secondary impacts to archeological or historical resources. In this instance, the stormwater system proposed by the Villages Inc. will function in a manner that replaces any water quantity or water quality functions lost by construction of the system. In its assessment of the possible cumulative impacts of the system, the District considered areas beyond the bounds of the current project, including the area to the south that is currently being reviewed under the DRI process as a substantial deviation. The District’s environmental scientist, Leonard Bartos, also reviewed that portion of the substantial deviation north of County Road 466A, in order to determine the types of wetlands present there. Furthermore, the District is one of the review agencies that comments on DRI and substantial deviation applications. When such an application is received by the District’s planning division, it is routed to the regulatory division for review. The District includes its knowledge of the DRIs in its determination that there are no cumulative impacts. Reasonable assurances have been provided as to these permitting criteria. Public Interest Balancing Test Because the proposed stormwater system will be located in, on, and over certain wetlands, the Villages Inc. must provide reasonable assurances that the system will not be contrary to the public interest. This assessment of this permitting criteria requires that the District balance seven factors. While the effects of the proposed activity will be permanent, the Villages Inc. has provided reasonable assurances that it will not have an adverse impact on the public health, safety, or welfare; on fishing or recreational values; on the flow of water; on environmental resources, including fish and wildlife and surface water resources; or on off-site properties. Furthermore, the District has carefully assessed the current functions being provided by the affected wetland areas. With respect to historical or archeological resources, the Villages Inc. has received letters from the Florida Department of State, Division of Historical Resources, stating that there are no significant historical or archeological resources on the project site that is the subject of this permit proceeding. Thus, the evidence establishes reasonable assurances that the Villages Inc.'s stormwater system will not be contrary to the public interest. Additionally, the District and Applicant presented uncontroverted evidence that the proposed project will not adversely impact a work of the District, and that there are no applicable special basin or geographic area criteria.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is: RECOMMENDED that a final order be entered issuing Water Use Permit Nos. 20012236.000 and 20012239.000 and Environmental Resource Permit No. 43020198.001, in accordance with the District’s proposed agency action.

The Issue The issue is whether an Environmental Resource Permit should be issued to KGB Lake Howell, LLC, authorizing the construction of a surface water management system to serve an apartment complex known as the Estates at Lake Howell in the City of Casselberry, Florida.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background In this proceeding, Respondent, St. Johns River Water Management District (District), proposes to issue an Environmental Resource Permit to Respondent, KGB Lake Howell, LLC (Applicant), authorizing the construction of a stormwater management system to serve a 240-unit apartment complex known as the Estates of Lake Howell. The project will be located on an undeveloped tract of land in the City of Casselberry (City), Seminole County, Florida, just north of the Orange County line. It will include ten three-story buildings, parking, clubhouse/ administration building, amenity complex, and wet detention pond. The project also incorporates a 3.62-acre stormwater pond, now owned and used by Seminole County (County), lying east of Lake Ann Lane across from the project site, which was included in the overall acreage calculations for the purpose of increasing apartment density on the site. The Applicant has authorization from the County to apply for the permit incorporating that tract of land. The pond will continue to function as a stormwater facility for the County and will not accommodate stormwater from the project site. The project site consists of 38.9 acres located on the north side of Howell Branch Road, east of State Road 436 (also known as Semoran Boulevard), and west of Lake Ann Lane in the City. The site is currently undeveloped and includes an abandoned orange grove and upland pine flatwoods community, which make up approximately 14.6 acres, while the remaining 24.3 acres is a mixed forested wetland system. The property is now owned by the Harold Kasik Living Trust (Kasik property), which has a contract for purchase with the Applicant. The Kasik property is in the shape of a rectangle, 648 feet by 2,530 feet, with its long sides running north- south. It is bordered on the north and east by single-family residential and vacant land, to the south by commercial development, and to the west by high-density residential and commercial development. The property has a high elevation of approximately 83 feet on its southeastern corner and falls to the north/northeast, where the edge of the wetland system is at an elevation of 63 or 64 feet. The major development constraint on the site is the large wetland tract on the northern portion of the property. In order to minimize proposed impacts to the wetlands, the Applicant proposed the transfer of the development entitlements from the County land to benefit the Applicant's property. More specifically, the Applicant will acquire the County property, the Applicant will simultaneously grant a perpetual drainage easement over the property to the County, the Applicant will maintain the landscaping of the property in perpetuity, the Applicant will convey around five acres of wetlands on the northern end of the Kasik property to the County in fee simple, and the City will allow the transfer of development rights from the property. The project will adversely impact 0.99 acres of low- quality wetlands, of which 0.72 acres are to be dredged and 0.27 acres are to be filled to provide the fencing around the wet detention facility. To offset this impact, the Applicant proposes to preserve 17.8 acres of forested wetlands, plus 1.2 acres of forested uplands, or a mitigation ratio of 18:1. The District's guidelines for preservation mitigation applicable to this project are 10:1 to 60:1 for wetland impacts and 3:1 to 20:1 for upland impacts; thus, the mitigation plan falls within these guidelines. Under current conditions, stormwater runoff from the project site sheet flows into the on-site wetland and ultimately Lake Howell (the Lake), a Class III water body which meets all applicable water quality standards and is not an Outstanding Florida Water. After development occurs, stormwater from the developed portions of the property will be conveyed to a wet detention pond for required water quality treatment and peak discharge rate attenuation. After treatment in the detention pond, the water will discharge to the on-site wetland, as it does now, and eventually will be conveyed into the Lake. Off-site flows will continue to be conveyed into the on-site wetland. The wet detention pond, which has a minimum depth of twelve feet and a permanent pool of water with a mean depth of two to eight feet, has been designed to accommodate a 25-year, 24-hour storm. Post-development discharge will be less than pre-development, and the outfall structure has been designed to avoid channelization in the wetlands after the point of discharge. Since at least the late 1940's, Petitioner, Shirley Haynes, or her relatives, have owned, or resided on, a multi-acre tract of land just north of the project site at 2764 Lake Howell Lane. She has substantial frontage on the south side of the Lake. The southern portion of her property, which are wetlands, adjoins the northern boundary of the project site. For the past three years, Petitioner, Egerton van den Berg, has resided on a ten-acre tract of land at 1245 Howell Point, which is northeast of the project site. He has approximately 235 feet of frontage on the south side of the Lake. As argued in their Proposed Recommended Order, Petitioners generally contend that the application is "materially deficient" in several respects in violation of Rule 40C-4.101; that the Applicant has failed to satisfy Rule 40C-4.301(1)(c) and (d), which in turn constitutes a failure to meet the requirements of Rule 40C-4.302(1)(a)-(c); that the Applicant failed to satisfy the criteria in Sections 12.2.3(a)-(f), 12.2.1, 12.2.1.1, 12.2.1.3, 12.2.2.3(a)-(e), 12.2.2.4(a) and (b), 12.3.2.2(c), and 12.3.8(a) of the Applicant's Handbook: Management and Storage of Surface Waters (Applicant's Handbook); that the District did not adequately consider the cumulative impacts of the project as required by Section 373.414(8)(a), Florida Statutes; that a low flow analysis of the Lake was not performed, as required by Rule 40C-8.011(5); that the Applicant did not submit detailed mitigation plans as required by Section 12.3.3.2 of the Applicant's Handbook; that the 18:1 ratio for mitigation proposed by the Applicant is inappropriate; and that the District should not approve the density of the apartments established by the City. These concerns, to the extent they have been identified as issues in the parties' Pre-Hearing Stipulation, are addressed in the findings below. Where contentions have been raised by Petitioners, such as the placement of the detention pond over a depressional area, and they have not been argued in the Proposed Recommended Order, they have been deemed to be abandoned. Conditions for issuance of permits Rule 40C-4.301(1)(a)-(k), Florida Administrative Code, specifies eleven substantive requirements for which reasonable assurance must be given in order for a standard permit to be issued. Subsection (3) of the same Rule provides that the standards and criteria contained in the Applicant's Handbook shall determine whether the foregoing reasonable assurances have been given. Additional conditions for the issuance of a permit are found in Rule 40C-4.302(1) when the project, or any part of it, is located in, on, or over wetlands or other surface waters. Therefore, because a part of the Applicant's system will be located in wetlands, the Applicant must also give reasonable assurance that the project will not be contrary to the public interest, and that it will not cause unacceptable cumulative impacts upon the wetlands or surface waters. a. Rule 40C-4.301 Paragraphs (a)-(c) of the Rule require that an applicant provide reasonable assurance that the project will not cause adverse water quantity impacts to receiving waters and adjacent lands, adverse flooding to on-site or off-site property, or adverse impacts to existing surface water storage and conveyance capabilities. If a system meets the requirements of Section 10.2.1(a) through (d) of the Applicant's Handbook, there is a presumption that the system complies with the requirements of Paragraphs (a) through (c). This presumption has been met since the evidence supports a finding that the post- development peak rate of discharge will be lower than the pre- development peak rate of discharge for a 24-hour, 25-year storm event. Therefore, the Applicant's system meets the requirements of these Paragraphs. Paragraph (d) of the Rule requires that an applicant give reasonable assurance that the project "will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters." To satisfy this requirement, an applicant must also demonstrate compliance with the two-prong test in Sections 12.2.2 and 12.2.2.4 of the Applicant's Handbook. Section 12.2.2 requires that an applicant provide reasonable assurance that a regulated activity will not impact the values of wetlands and other surface water functions so as to cause adverse impacts to the abundance, diversity, and habitat of fish, wildlife, and listed species. In its proposal, the Applicant proposes to fill a total of 0.99 acres of wetlands. Since these impacts will eliminate the ability of the filled part of the on-site wetland to provide functions to fish and wildlife, the filling will cause adverse impacts. Under these circumstances, Section 12.2.1.1 requires that the Applicant either implement practicable design modifications to reduce or eliminate these adverse impacts or meet one of the exceptions under Section 12.2.1.2. Under Section 12.2.1.1, a proposed modification which is not technically capable of being done, is not economically viable, or which adversely affects public safety through the endangerment of lives or property is not considered practicable. The Applicant’s design for the proposed project went through a number of iterations prior to submittal to the District to reduce adverse impacts to the wetlands. During the permitting process, the District requested that the Applicant consider a number of other suggestions to reduce or eliminate the adverse impacts to wetlands such as adding a fourth floor to the apartment buildings to eliminate the need for one apartment building, building a parking garage for the tenants, and eliminating the tennis and volleyball courts. Because the Applicant provided detailed reasons why none of those suggestions were practicable, it was not required to implement any of those design modifications. In addition, the Applicant’s decision not to include a littoral zone around the stormwater pond did not increase the amount of wetland impacts as that engineering decision resulted in a stormwater pond that was simply deeper and not wider. Therefore, the Applicant has met the requirement to reduce or eliminate adverse wetland impacts. Section 12.2.1.1 only requires an elimination and reduction analysis when: (1) a proposed system will result in adverse impacts to wetland functions and other surface water functions so that it does not meet the requirements of Sections 12.2.2 through 12.2.3.7, or (2) neither one of the two exceptions within Section 12.2.1.2 applies. In determining whether one of the two exceptions in Section 12.2.1.2 applies, the District must evaluate the long- term ecological value of the mitigation proposed by the Applicant. If the mitigation is not adequate to offset the adverse impacts of the proposed system, then it is unlikely either exception in Section 12.2.1.2 will apply. As noted above, the Applicant’s proposed dredging and filling of the southern edge of the wetlands on the project site will eliminate the ability of that wetland area to provide functions to fish and wildlife. However, the Applicant’s mitigation plan of placing 17.8 acres of wetlands and 1.2 acres of uplands under a conservation easement to preserve that property in its natural state in perpetuity will fully replace the types of functions that the part of the wetlands proposed to be impacted provides to fish and wildlife. The mitigation plan will also offset the adverse impacts that this project will have on the value and functions provided to fish and wildlife by the impacted part of the wetlands. In this case, the first exception under Section 12.2.1.2(a) applies as it meets that Section's two requirements: the ecological value of the functions provided by the area of wetland to be adversely affected is low, and the proposed mitigation will provide greater long-term ecological value than the area or wetland to be adversely affected. Also, the quality of the wetland to be impacted is low. All of the proposed impacts will occur in the area of the wetland that was historically disturbed and in which nuisance and exotic species are prevalent. Due to nuisance and exotic vegetation, the ecological value provided by that area to wildlife is low. The mitigation for the proposed project will provide greater long-term ecological value to fish and wildlife than the part of the wetland proposed to be impacted because the proposed mitigation will preserve eighteen times more wetlands that are of higher quality and provide greater value than the wetland area to be impacted. The type of wetland to be preserved, a mixed forested wetland containing hardwoods, is rare for the area. Although the mitigation plan will provide greater long-term ecological value to fish and wildlife than the part of the wetland proposed to be impacted, the Applicant did not meet the second exception in the elimination and reduction rule under Section 12.2.1.2(b) because the wetlands to be preserved are not regionally significant. In addition to meeting the elimination and reduction rule through implementation of practicable design modifications, the Applicant also satisfied the same rule by meeting the first exception found in Section 12.2.1.2(a). Thus, the Applicant has satisfied Section 12.2.2, which is the first prong of the test to determine compliance with Paragraph (d). The second prong of the test to determine whether Paragraph (d) of the Rule has been satisfied is found in Section 12.2.2.4. That Section requires that an applicant give reasonable assurance that the activity will not change the hydroperiod of a wetland so as to affect wetland functions. For the following reasons, that prong of the test has been satisfied. Since the wetlands are primarily groundwater-influenced, the construction of the stormwater pond between the project and the wetlands will not adversely affect the wetlands. As the soils surrounding the pond are very porous with a high infiltration and percolation rate, water from the stormwater pond will still reach the wetlands through lateral seepage. Further, the Applicant will install an energy dissipating device on the outfall spout at the point of discharge so that water will be spread out from the stormwater pond as it discharges into the receiving wetlands. As noted earlier, this will prevent an adverse channelization effect. Finally, stormwater runoff from the surrounding basins that currently discharge into the wetlands will not be affected by the construction of the stormwater system. That runoff will continue to flow into the wetlands on the project site. Because the Applicant has satisfied Sections 12.2.2 and 12.2.2.4, Paragraph (d) of the Rule has been met. Paragraph (e) of the Rule generally requires that an applicant provide reasonable assurance that a project will not adversely affect the quality of receiving waters. Here, the Applicant has provided such assurance. This is because the system has been designed in accordance with all relevant District criteria. Also, the Applicant has proposed to revise Permit Condition 26 as follows: Condition 26. This permit authorizes construction and operation of a surface water management system as shown on the plans received by the District on June 14, 2001, and as amended by plan sheet C4 (Sheet 07 of 207) received by the District on January 23, 2002. In view of this revision, the Applicant's wet detention system complies with all of the design criteria contained in Rule 40C-42.026(4). Under Rule 40C-42.023(2)(a), compliance with the design criteria contained in Rule 40C-42.026 creates a presumption that state water quality standards, including those for Outstanding Florida Waters, will be met. This presumption has not been rebutted; therefore, the requirements of Paragraph (e) of the Rule have been satisfied. Further, Sections 12.2.4.1 and 12.2.4.2 state, in part, that reasonable assurance regarding water quality must be provided both for the short term and the long term, addressing the proposed construction, alteration, operation, maintenance, removal, and abandonment of the system. The Applicant has provided reasonable assurance that this requirement is met through the design of its surface water management system, its long-term maintenance plan for the system, and the long and short-term erosion and turbidity control measures it proposes. If issued, the permit will require that the surface water management system be constructed and operated in accordance with the plans approved by the District. The permit will also require that the proposed erosion and turbidity control measures be implemented. Section 12.2.4.5 does not apply because there are no exceedances of any water quality standards at the proposed receiving water. Also, Sections 12.2.4.3 and 12.2.4.4 do not apply because the Applicant has not proposed any docking facilities or temporary mixing zones. Paragraph (f) of the Rule requires that an applicant not cause adverse secondary impacts to the water resources. Compliance with this requirement is determined by applying the four-part test in Section 12.2.7(a) through (d). As to Section 12.2.7(a), there are no secondary impacts from construction, alteration, and intended or reasonably expected uses of the proposed system that will cause water quality violations or adverse impacts to the wetland functions. The Applicant chose not to provide buffers abutting the wetlands but rather chose measures other than buffers to meet this requirement. The Applicant has provided reasonable assurance that secondary impacts will not occur by placing the stormwater pond between the planned project and the wetlands, so that the pond itself will serve as a buffer by shielding the wetland from the lighting and noise of the project, and by acting as a barrier to keep domestic animals out of the wetlands. In addition, the Applicant increased the amount of property to be preserved as mitigation by adding 2.97 acres of wetlands and 1.2 acres of uplands to the mitigation plan to mitigate for any remaining secondary impacts. Accordingly, the first part of the secondary impacts test in Section 12.2.7(a) is satisfied. As to Section 12.2.7(b), because there is no evidence that any aquatic or wetland-dependent listed animal species use uplands for existing nesting or denning adjacent to the project, the second part of the test has been met. No adverse secondary impacts will occur under the third part of the test in Section 12.2.7(c) because the proposed project will not cause impacts to significant historical or archaeological resources. Finally, adverse secondary impacts as proscribed by Section 12.2.7(d) will not occur because no evidence was presented that there would be additional phases or expansion of the proposed system or that there are any onsite or offsite activities that are closely or causally linked to the proposed system. Therefore, the proposed project satisfies Paragraph (f) of the Rule. Paragraph (g) of the Rule requires that an applicant provide reasonable assurance that a project will not adversely impact the maintenance of surface or ground water levels or surface water flows established in Chapter 40C-8. Minimum (but not maximum) surface water levels have been established for the Lake pursuant to Chapter 40C-8 for the basin in which the project is located. The project will not cause a decrease of water to, or cause a new withdrawal of water from, the Lake. Therefore, the project satisfies this requirement. Finally, Petitioners have acknowledged in their Proposed Recommended Order that the Applicant has given reasonable assurance that the requirements of Paragraphs (h), (i), (j), and (k) have been met. The parties have also stipulated that the receiving water (Lake Howell) meets all Class III water quality standards. Therefore, the project satisfies the requirements of Subsection 40C-4.301(2). Rule 40C-4.302 - Public Interest Test Under Rule 40C-4.302(1)(a)1.-7., an applicant must provide reasonable assurance that the parts of its surface water management system located in, on, or over wetlands are not contrary to the public interest. Similar requirements are found in Section 12.2.3. The Applicant has provided reasonable assurance that the parts of the project that are located in, on, or over wetlands (mainly the detention pond and fill) are not contrary to the public interest, because the evidence showed that all seven of the public interest factors to be balanced are neutral. Because the proposed permanent mitigation will offset the project’s adverse impacts to wetlands, no adverse effects to the conservation of fish and wildlife due to the project’s permanent nature will occur. The evidence also showed that best management practices and erosion control measures will ensure that the project will not result in harmful erosion or shoaling. Further, it was demonstrated that the project will not adversely affect the flow of water, navigation, significant historical or archaeological resources, recreational or fishing values, marine productivity, or the public health, safety, welfare or property of others. Finally, the evidence showed that the project’s design, including permanent mitigation, will maintain the current condition and relative value of functions performed by parts of the wetland proposed to be impacted. Therefore, the project meets the public interest criteria found in Rule 40C-4.302(1)(a). Rule 40C-4.302(1)(b) - Cumulative Impacts Rule 40C-4.302(1)(b) and Section 12.2.8 require that an applicant demonstrate that its project will not cause unacceptable cumulative impacts upon wetlands and other surface waters within the same drainage basin as the regulated activity for which the permit is being sought. Under this requirement, if an applicant proposes to mitigate the adverse impacts to wetlands within the same drainage basin as the impacts, and if the mitigation fully offsets these impacts, the District will consider the regulated activity to have no unacceptable cumulative impacts upon wetlands and other surface waters. The Applicant has chosen to mitigate for the impacts to 0.99 acres of wetlands by preserving 17.8 acres of wetlands and 1.2 acres of uplands on-site. Since this mitigation will occur in the same drainage basin as the impacts and the mitigation fully offsets those impacts, the Applicant satisfies the requirements of the Rule. Rule 40C-4.302 - Other Requirements The parties have stipulated that the requirements of Paragraphs (c) and (d) of Rule 40C-4.302(1) do not apply. There is no evidence that the Applicant has violated any District rules or that it has been the subject of prior disciplinary action. Therefore, the requirements of Subsection (2) of the Rule have been met. Miscellaneous Matters County Pond Site The Seminole County pond site located on the east side of Lake Ann Lane and across the street from the project is not a jurisdictional wetland and does not have any wetland indicators. It is classified as an upland cut surface water. The Applicant is not proposing to impact any wetlands at the pond site, and the site is not part of the proposed mitigation plan for the project. The permit in issue here is not dependent on the pond site, and nothing in the application ties the project with that site. Indeed, the transfer of density rights from the County property is not relevant to the District permitting criteria. Review of Application When the decision to issue the permit was made, the District had received all necessary information from the Applicant to make a determination that the project met the District's permitting criteria. While certain information may have been omitted from the original application, these items were either immaterial or were not essential to the permitting decision. The application complies with all District permitting criteria. Contrary to Petitioners' contention, the Applicant does not have to be the contract purchaser for property in order to submit an application for that property. Rather, the District may review a permit application upon receipt of information that the applicant has received authorization from the current owners of the property to apply for a permit. In this case, the Applicant has the permission of the current owners (the Harold Kasik Living Trust).

The Issue The issue in this case is whether the Southwest Florida Water Management District (the District) should grant the application of the Misty Creek Country Club, Inc. (the Club), to modify MSSW Permit No. 400037.
Findings Of Fact Background Petitioners are owners of property adjacent to Lake No. 7 of the Misty Creek Country Club in a development called The Preserves at Misty Creek-- specifically, lot 113 (Robert and Lee Werner), lot 114 (Charles and Rosemary Biondolillo), lots 115 and 115A (Ignatius and Judith Bertola), lots 117 and 117A (Don and Halina Bogdanske), lots 118 and 118A (Louis and Betty Mitchell), lots 119 and 119A (George and Dorothy Holly), lots 120 and 120A (John and Maureen Higgins), and lot 121 (William and June Spence). Respondent, the Misty Creek Country Club (the Club), operates a golf course and country club located at The Preserves at Misty Creek under a 99-year lease with Gator Creek Lands, the developer of The Preserves at Misty Creek. Existing System Design and Application for Permit Modification In 1985, Respondent Southwest Florida Water Management District, issued a surface water management permit for development of a 730-acre residential development and golf course. The District subsequently issued to the Club operation phase authorization for the surface water management system associated with the golf course portion of the development in March of 1992. Under the original permit, Lake No. 7 was part of the overall stormwater management system for the golf course. The lake is approximately seven and half to eight acres in size and is part of a total drainage basin of approximately twenty-eight acres. As originally designed, Lake No. 7 is a detention with filtration system. An underdrain in the side of the bank provides water quality treatment, filtering out oils and greases, fertilizers and other contaminants. A control elevation of 31.02 was established for Lake No. 7 through construction of a weir. Between elevation 31.00 and 31.02, water discharges through the underdrain system providing water quality treatment. Above elevation 31.02, water flows over the control structure into Lake No. 6, and ultimately discharges to Cow Pen Slough, which is Class III waters of the state. The Club presently has a water use permit from the District which allows withdrawal of groundwater for irrigation of the golf course. Groundwater is stored in Lake No. 7 prior to use for irrigation when needed to augment water in the lake. Special Condition Number 2 of the water use permit required the Club to investigate the feasibility of using reclaimed or reuse water in lieu of groundwater for irrigation purposes at the golf course. As a result of the investigation required by Special Condition Number 2 of the water use permit, the Club filed an application with the District to modify its surface water management permit to allow for the introduction of reuse water into Lake No. 7. Under that application, there would have been no significant modifications to the stormwater management system. Reuse water would have replaced groundwater as a source for augmenting water in the lake when needed for irrigation. An eight-inch service line would convey the reuse water to Lake 7, and a float valve would control the introduction of reuse water into Lake No. 7. When water levels in the lake fell below elevation 30.5', the float valve would open the effluent line to allow introduction of reuse water into the lake; when the water elevation in the lake reached 31.0', the float valve would shut off the flow of water. There would be gate valves on either side of the structure that could be manually closed, if necessary, to stop the flow of reuse water into the lake if the float valve malfunctioned. Club personnel would have access to the gate valves and could manually stop the flow of reuse water into the lake if necessary. On August 9, 1995, just days prior to the final hearing in this matter, the Club proposed to modify its application to make certain structural changes in the design of the surface water management system. Specifically, the Club proposed to plug the window in the weir, raise the elevation of the weir or control structure to elevation 33.6, raise the elevation of the berm along the north end of Lake No. 7 adjacent to the weir to elevation 33.6, and plug the underdrain. The purpose of the proposed modifications to the design of the system was to assure that no discharge from Lake No. 7 would occur up to and including the 100-year storm event. A 100-year storm event is equal to 10 inches of rainfall in a 24-hour period. Source and Quality of Reuse Water The Club also entered into an agreement with Sarasota County to accept reuse water from the county's new Bee Ridge wastewater treatment facility. That agreement specifies the terms under which the Club will accept reuse water from the County. The County's Bee Ridge facility is presently under construction and is not yet operating. As permitted by the Department of Environmental Protection, the Bee Ridge wastewater treatment facility will use a Bardenpho waste treatment system which is a licensed process to provide advanced waste treatment. The construction permit establishes effluent limits for the facility that are comparable to a level of treatment known as advanced secondary treatment, but the County Commission for Sarasota County has instructed the County staff to operate the Bee Ridge facility as an advanced waste treatment plant. Advanced waste treatment is defined by the quality of the effluent produced. For advanced waste treatment, the effluent may not exceed 5 milligrams/Liter of biochemical oxygen demand (BOD) or total suspended solids (TSS), 3 milligrams/Liter of total nitrogen, or 1 milligram/Liter of total phosphorus. It also requires high level disinfection. Advanced secondary treatment requires the same level of treatment for TSS but the limit for nitrates is 10 milligrams/Liter. High level disinfection is also required for advanced secondary treatment. In Florida, reuse systems require a minimum of advanced secondary treatment. High level disinfection is the level of treatment that generally is accepted as being a reasonable level of treatment. The Bee Ridge permit issued to Sarasota County identifies the Club as one of the recipients of reuse water for irrigation. Condition Number 21 of that permit provides that the use of golf course ponds to store reuse water is not authorized under the County's permit until issuance of a separate permit or modification of the County's permit. Although the District did not require Misty Creek to submit any information about the modification of the County's permit, there was no basis for assuming that the County permit could not be modified. To the contrary, the permit provides that authorization may be obtained by permit modification. Under the late modification to the Club's application, the reuse water transmission line and float valve system, with backup manual gate valve system, is unchanged. So are the water elevations at which the float valve system will automatically introduce reuse water into Lake 7 and shut off. Sarasota County already has constructed the water transmission system that would deliver reuse water to the Club. At the request of the District, the Club provided copies of the drawings of the float valve structure as permitted by the Department of Environmental Protection. The District did not require certified drawings of that structure. But the District will require the Club to provide as-built drawings following completion of construction prior to the introduction of reuse water into Lake No. 7. Property Ownership Each of the Petitioners owns a residential lot adjacent to Lake No. 7. At the time of the Petitioners' purchase of the individual residential lots, the Club leased certain property immediately west of Lake No. 7 from the developer of The Preserve at Misty Creek. The leased premises included a piece of land extending into the lake known as the 19th green. As a result of negotiations between the Club and the developer, it was determined that the 19th green would be removed and the land between the approximate top of bank of Lake No. 7 and the private residential lots would be released from the Club's lease. The developer subsequently conveyed the property that had been released from the Club's lease to the individual lot owners (the "A" parcels listed in Finding 1). At the time of the conveyance of the additional parcels, the attorney for the developer prepared deeds for each individual parcel with a metes and bounds description off the rear of the residential lots to which they were being added. While the Club's application for modification of its surface water management permit was being processed by the District, counsel for Petitioners provided the District with copies of the individual deeds and questioned whether the Club had ownership or control of the land which was the subject of the application sufficient to meet the District's permitting requirements. In response to a request for information regarding the ownership of the property that was the subject of the application, the Club submitted to the District a topographical survey prepared by Mr. Steven Burkholder, a registered professional land surveyor with AM Engineering. The topographical survey depicted: the elevation of the water in the Lake No. 7 on the day that the survey was conducted, labeled "approximate water's edge"; the elevation of the "top of bank"; and the easternmost line of private ownership by Petitioners. Mr. Burkholder determined the line of private property ownership by reproducing a boundary survey attached to the individual deeds conveying the additional parcels to the Petitioners. He testified that he was confident that the topographical survey he prepared accurately represented the most easterly boundary of the Petitioners' ownership. The elevation of the line of private ownership as depicted on the survey prepared by Mr. Burkholder ranges from a low of approximately 34.5 to 35.2. The elevation of the line labeled "top of bank" ranges from a high of 35.6 to a low of 34.4. The elevation of the water in Lake No. 7 would be controlled by the elevation of the modified control structure which is proposed to be set at elevation 33.6. After modification of the surface water management system to retain the 100-year storm event, at no time would water levels in the lake rise above the existing elevation of the "top of bank." The Petitioners testified that they believed that they owned to the water's edge or edge of the lake, but Mr. Burkholder testified that a property boundary could not be determined based on an elevation depicting the water's edge because that line would change as the level of the water rose and fell. The Petitioners also presented evidence that the developer's attorney made representations to them that their ownership extended to the "approximate high water line." But there appears to be no such thing as an "approximate high water line" in surveying terms. Where the boundary of a lake is depicted on a survey it generally is depicted from top of bank to top of bank. In any event, the legal descriptions of the parcels conveyed to the Petitioners were not based on a reference to either a water line or the water's edge or the lake at all. Instead, the legal descriptions were based solely on a metes and bounds description off the rear of the residential lots. Notwithstanding some contrary evidence, if the Petitioners owned to the water's edge, such ownership would require the Petitioners to consent to or join in the amended application for the modification of the Club's surface water management permit. Information regarding the ownership or control and the legal availability of the receiving water system is required as part of the contents of an application under Rule 40D-4.101(2)(d)6. and 7., Florida Administrative Code. The amended application requires the ability to "spread" Lake 7 in the direction of the Petitioners' property. If the Petitioners own the property on which the Club intends to "spread" Lake 7 in order to make the amended application work, the Petitioners must consent or join. The issue of the legal ownership and control of the Petitioners and the Club currently is in litigation in state circuit court. If the state circuit court determines that the easterly boundary of the "A" parcels lies to the east of the "top of bank," consideration would have to be given to modifying any permit issued to the Club to insure that the designed "spread" of Lake 7 in a storm event up to and including a 100-year storm event does not encroach on the Petitioners' property. District Permit Requirements The District has never before processed an application for a surface water management permit allowing commingling of storm water and reuse water. The District applied Chapter 40D-4, Florida Administrative Code, in reviewing the Club's permit application. There are no specific provisions in Rule 40D-4 or the District's Basis of Review for Surface Water Management Permit Applications that address the commingling of stormwater and reuse water; on the other hand, no rules of the District prohibit the introduction of other types of water into a stormwater treatment pond so long as the requirements of Rule 40D-4 are met. The District has the authority to allow stormwater and reuse water to be commingled. Section 40D-4.301, Florida Administrative Code, contains the conditions for issuance of a surface water management permit. Permitting Criteria In order to obtain a surface water management permit to commingle stormwater and reuse water in Lake 7, the Club must provide reasonable assurances that the proposed modifications to its existing system will provide adequate flood control and drainage; not cause adverse water quality and quantity impacts on receiving waters and adjacent lands; not result in a violation of surface water quality standards; not cause adverse impacts on surface and groundwater levels and flows; not diminish the capability of the lake to fluctuate through the full range established for it in Chapter 40D-8, Florida Administrative Code; not cause adverse environmental impacts to wetlands, fish and wildlife or other natural resources; be effectively operated and maintained; not adversely affect public health and safety; be consistent with other public agency's requirements; not otherwise be harmful to water resources of the District; and not be against public policy. No surface or groundwater levels or flows have been set for this area of the District, so that permit criterion is not applicable to the Club's application. The Club's application will not impact wetlands or fish and wildlife associated with wetlands as described in F.A.C. Rule 40D-4.301(1)(f). There are no wetlands regulated by the District in the project site. The Club has submitted to the District an operation and maintenance plan for the modified surface water management system. The operation and maintenance plan is in compliance with the District's permitting criteria contained in Rule 40D-4.301(1)(g). The District's regulation with respect to the requirement that a project not adversely affect the public health and safety is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The permitting criterion that a project must be consistent with the requirements of other public agencies was met by inclusion in the permit of Special Conditions Nos. 5 and 6, Limiting Condition No. 3 and Standard Condition No. 3, which require that the surface water management permit be modified if necessary to comply with modifications imposed by other public agencies. The District's regulation with respect to the requirement that a project not otherwise be harmful to the water resources within the District is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The District's regulation with respect to the requirement that a project may not be against public policy is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with that criterion. The project will not have an adverse impact on water quality or quantity in receiving waters or adjacent lands. Under the District's regulations, the project would not be permittable if it caused flooding on property owned by other persons. Two concerns regarding off-site flooding were raised by Petitioners: first, the potential for flooding of the Petitioners' property; and, second, the potential for flooding of secondary systems connecting to Lake No. 7 such as private roads in the development. The project would violate the requirements of Section 40D-4.301(1)(a), Florida Administrative Code, which requires that a proposed project provide adequate flood protection and drainage, if raising the weir and berm elevation to 33.6 would cause the level of water in Lake No. 7 to move laterally up the bank and encroach on property owned by Petitioners. However, the Club has given reasonable assurances that the Petitioners own only to the "top of bank" and that raising the weir elevation to 33.6 would not cause water levels to rise above the "top of bank" of the lake. If it is determined in pending state circuit court proceedings that the Petitioners own beyond the "top of bank," any permit for the Club's project might have to be modified to avoid flooding the Petitioners' property. With respect to potential flooding of secondary systems, such as adjacent roadways, raising the elevation of water in Lake No. 7 would decrease the capacity of the storm sewers draining into the Lake. However, the proposed modifications would not increase the area of impervious surface in the drainage basin or decrease the size of the lake, and water levels in the roadways probably would not rise much higher than under present circumstances. The existing storm sewer system is only designed for a 10-year storm event, so the supplemental effect on roadway flooding from retaining a 100-year storm event in Lake No. 7 probably would be negligible. The Club gave reasonable assurances that any increase in water levels on the roadways from the proposed modifications would not be considered a significant adverse effect because it still would not affect public access. Sarasota County's land development regulations allow flooding in streets of up to 12 inches for a 100-year storm event, nine inches for a 25-year storm event, and six inches for a 10-year storm event. No portion of the proposed project area is within the 100-year floodplain. The project will not have an adverse effect on water quantity attenuation or cause flooding of the Petitioners' property or secondary systems, such as adjacent roadways. Petitioners have protested the effect that this project will have on water quality within Lake No. 7, itself. Surface water quality standards do not apply within a stormwater pond. Stormwater ponds are essentially pollution sinks intended to receive polluted runoff. Where there is no discharge from a pond, water quality treatment is irrelevant. Lake 7 is not a "water resource within the District" pursuant to Section 40D-4.301(1)(j), Florida Administrative Code, and potential impact on water quality in Lake No. 7 should not be considered. Section 40D-4.301(1)(j) limits the issues to be considered by the District to downstream water quality, water quantity, floodplain impacts, and wetlands impacts. The commingling of wastewater effluent treated to a level of advanced secondary or advanced waste treatment (reuse water) would improve water quality within a stormwater treatment pond at least 90 to 95 percent of the time. Stormwater is very low quality compared to reuse water. In most respects, reuse water also will be better quality than the well water presently being used to augment the pond. It is expected to be better quality than unimpacted water in the receiving waterbody with respect to nitrogen content and only slightly worse with respect to phosphorus content. The addition of reuse water should not promote more algal growth; rather, it should reduce the likelihood of algal growth. It also should not increase the incidences of fish kills in Lake 7. Nor should it alter the nutrient concentrations in Lake 7 so as to result in an imbalance of the natural population of aquatic flora and fauna. In the draft permit originally proposed to be issued to the Club, permit conditions required that water quality be monitored at the point of discharge to waters of the state. This requirement was eliminated from the revised permit as the District determined that it was not necessary in light of the modification of the system to retain the 100-year storm event. The subject design does not account for recovery of the water quality treatment volume within a specified period of time. However, there is no such requirement in District rules when a pond entirely retains the 100-year storm event, as is the case with this project. Even if there were a discharge from the surface water management system in a storm event up to and including a 100-year storm event, the Club gave reasonable assurances that water quality standards in the receiving waterbody would not be violated because of the effects of dilution. This project will not cause discharges which result in any violations of applicable state water quality standards for surface waters of the state. Based on a number of factors, including the peak rate factor, the curve number and the seasonal high water elevation, the water level in Lake 7 would reach an elevation of 33.57 if a 100-year storm event occurs. This results in the retention of the 100-year storm in Lake 7. The District only considers the 100-year storm event, by itself. It does not consider other rainfall events before or after it. However, the District does presume that ponds are at their seasonal high water level when the 100-year storm event occurs and that the ground is saturated. With respect to the seasonal high water level, there was substantial conflicting testimony. The Club's consultant used a seasonal high water level of 31.0' for Lake No. 7 in his calculations. This was based on a geotechnical engineering report prepared by Ardaman & Associates. A seasonal high water elevation of 31.0' was also used in the original permit application in 1985. In concluding that the seasonal high water level should be 31.0, the Ardaman report relied on several assumptions, including plugging of the underdrain and overflow weir and no discharges into or pumping out of the lake. These assumptions were made to establish an historical water level. The Petitioners' consultant disputed the determination in the Ardaman report that the seasonal high for Lake No. 7 was 31 on the grounds that the report indicated groundwater levels of 32.8 on three sides of the lake. He also felt that water levels would rise in the lake over time as a result of it being, allegedly, a closed system. While he did not have an opinion as to what the appropriate seasonal high should be, he felt it would be higher than 31 but lower than 32.8. However, he did no modeling with respect to calculating a seasonal high water level and would normally rely on a geotechnical engineer, such as Ardaman & Associates, to calculate seasonal high water levels. The District generally does not receive information as extensive and detailed as that included in the Ardaman report when it reviews permit applications. Among other things, the Ardaman report indicates a gradient across Lake No. 7 which makes the determination of the seasonal high for the lake difficult. The groundwater flow gradient results from the fact that the elevation of Lake No. 6 is approximately three feet lower than the elevation in Lake No. 7. The elevation determined by Ardaman may well be conservative in that the seasonal high of 31 is above the midpoint of the gradient. Although Lake 7 will be designed as an essentially closed system, it will have inflow from rainfall, surface runoff, introduction of reuse water and groundwater inflow, and outflows by way of evapotranspiration, withdrawal for irrigation purposes, and groundwater outflows. To alleviate any concerns about the validity of the seasonal high, it would be reasonable to include a permit condition requiring the Club to monitor the water level in Lake 7 on a daily basis, using staff gauges, after modification of the control structure. If such monitoring indicated that the seasonal high water level exceeds 31.0, the District could consider options to address that situation, including reducing the level at which reuse water is introduced into the lake or requiring water quality monitoring at the point of discharge to receiving waters. Groundwater quality is regulated by the Department of Environmental Protection, not by the District. The DEP permit issued to Sarasota County for disposal of reuse water at the Club golf course requires the installation of two groundwater monitoring wells, one in fairly close proximity to Lake No. 7. The Overlooked Pond There is a small retention pond northwest of Lake 7, near lot 113. Neither the Club nor the District considered the effect of the Club's late modification of its application on the retention pond northwest of Lake 7 and adjacent properties. Lake 7 and the retention pond to its northwest are connected by an equalizer pipe. As a result, water levels in the pond will be affected by water levels in Lake 7. There was no evidence as to the elevations of the banks of the retention pond. There was no evidence as to whether the modifications to the Club's application will result in flooding of properties adjacent to the pond. There was no evidence that the Club owns or controls the retention pond or the properties adjacent to it that might be affected by flooding that might result from the modifications to the Club's application.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Southwest Florida Water Management District enter a final order denying the Club's amended application. RECOMMENDED this 19th day of October, 1995, in Tallahassee, Florida. J. LAWRENCE JOHNSTON 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 19th day of October, 1995. APPENDIX TO RECOMMENDED ORDER, CASE NO. 95-2196 To comply with the requirements of Section 120.59(2), Fla. Stat. (1993), the following rulings are made on the parties' proposed findings of fact: Petitioners' Proposed Findings of Fact. 1.-2. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease. Accepted and incorporated. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease and from which the western extent of the Club's leasehold interests in Lake 7 can be determined. Accepted and incorporated. But the topographic survey, together with other evidence, does show the eastern extent of the Petitioners' property in relation to the "top of bank" of Lake 7 and the western extent of the Club's leasehold interests in Lake 7. Rejected as contrary to the greater weight of the evidence that uses must be "specifically authorized" in that the lease authorizes the use of the premises for a "golf course," which is presumed to include uses inherent to the operation of a golf course that may not be further specified in the lease, such as drainage facilities, like Lake 7, and facilities for irrigation of the golf course. Otherwise, accepted and incorporated to the extent not subordinate or unnecessary. Rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as contrary to the greater weight of the evidence that the Club does not pay for the maintenance of Lake 7, at least as between the Club and its lessor, which is the subject of the pertinent lease provision. (There was evidence as to a dispute between the Club and the Petitioners, or at least some of them, as to who is responsible for maintenance of land in the vicinity of the western extent of Lake 7 and the eastern extent of the Petitioners' property. Rejected as contrary to the greater weight of the evidence. Rejected as contrary to the greater weight of the evidence to the extent that there are "A" parcels between lots 115 through 120 and Lake 7. Otherwise, accepted and incorporated. Accepted and incorporated. Not clear whether all of the activities listed in the second sentence are done in the entire area up to the water's edge but, otherwise, accepted and incorporated. Accepted, but subordinate to facts contrary to those found, and unnecessary. Accepted; subordinate to facts found. Rejected. The intent of the parties is not clear and is the subject of litigation in state circuit court. 17.-18. Accepted that some probably used the words "to the water's edge"; others may have said "to the lake" or "to the approximate high water line." Regardless of what they said, the legal consequences are being litigated in state circuit court. Subordinate to facts contrary to those found, and unnecessary. 19.-20. Accepted and incorporated to the extent not subordinate or unnecessary.. Last sentence, accepted but subordinate and unnecessary. The rest is rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. The evidence was sufficient to place on Exhibit M-16 the boundary lines of the "A" parcels, as depicted on the Alberti boundary survey that was attached to the individual deeds to all of the "A" parcels, in relation to the "top of bank" of Lake 7 and other topographical features depicted on Exhibit M-16. The 0.679 acre total for the "A" parcels was merely transcribed from the Alberti boundary survey (probably incorrectly, as the boundary survey seems to indicate the acreage to be 0.674, plus or minus.) Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, it will spread more than before the modifications, up to a maximum spread of approximately ten feet. Rejected as contrary to the greater weight of the evidence. The Club gave reasonable assurances that the spread would be contained within its leasehold interest. However, consideration would have to be given to modifying the permit if the state circuit court determines in the pending litigation that the easterly boundary of the "A" parcels lies to the east of the "top of bank." Accepted and incorporated to the extent not conclusion of law. Accepted. Self-evident and unnecessary. Accepted and incorporated. Accepted, but subordinate, and unnecessary. Accepted and incorporated. Rejected as contrary to the greater weight of the evidence. It does not prohibit it; it just does not authorize it. It provides that authorization may be obtained by permit modification. Accepted and incorporated to the extent not subordinate or unnecessary. 32.-36. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) 37. Rejected as contrary to the greater weight of the evidence that discharges will be "likely." (Accepted and incorporated that no discharges are expected as a result of storm events up to and including a 100-year storm event unless preceding conditions predispose the system to discharge during a 100-year storm event.) 38.-39. Accepted but subordinate and unnecessary. (As for 39., very little construction will be required for the proposed project.) Rejected as contrary to the greater weight of the evidence. First, Lake 7 will not be "maintained" at 31'; rather, when it falls below 30.5', a half inch will be added. Second, it is not clear that the Ardaman report established an "artificially low seasonal high water level." (There is a hydraulic gradient across Lake 7 from east to west, approximately. The Ardaman report assumed no flow into or out of Lake 7; it also assumed no pumpage into or out of the lake.) Rejected as contrary to the greater weight of the evidence that it is based "solely" on that assumption. Accepted and incorporated that it is based on that and on other assumptions. Accepted and incorporated. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) Rejected as not supported by evidence. Rejected as contrary to the greater weight of the evidence to the extent that the impact is obvious--the water level in the pond will be approximately equal to the water level in Lake 7. Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, so will the water level in the pond. 47.-48. Accepted and incorporated. 49.-50. Accepted but subordinate and unnecessary. 51.-52. Accepted and incorporated. Respondents' Proposed Findings of Fact. 1.-7. Accepted and incorporated. 8. Rejected as contrary to the greater weight of the evidence in that there was more to the application than just substitution of reuse for well water. 9.-10. Accepted and incorporated. 11. Accepted and incorporated to the extent not subordinate or unnecessary. 12.-22. Accepted and incorporated. Rejected as not proven. (The two District witnesses disagreed.) Even if true, subordinate to facts contrary to those found. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted and incorporated. Accepted and incorporated to the extent not conclusion of law. 28.-29. Accepted; subordinate to facts found, and in part conclusion of law. 30. Accepted. First sentence, incorporated; second sentence, subordinate to facts found, and in part conclusion of law. 31.-35. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted but subordinate to facts contrary to those found. 39.-40. Accepted and incorporated to the extent not subordinate or unnecessary. 41.-43. Accepted and incorporated. Accepted and incorporated to the extent not conclusion of law. Last sentence, accepted and incorporated to the extent not conclusion of law; rest, accepted but subordinate to facts contrary to those found, and in part conclusion of law. Accepted and incorporated to the extent not subordinate or unnecessary. Accepted, but subordinate, and unnecessary. Accepted and incorporated. First sentence, accepted but subordinate to facts contrary to those found; second sentence, accepted and incorporated to the extent not conclusion of law.

The Issue The issue to be determined is whether Consumptive Use Permit No. 2-083-91926-3, and Environmental Resource Permit No. IND-083-130588-4 should be issued as proposed in the respective proposed agency actions issued by the St. Johns River Water Management District.
Findings Of Fact The Parties Sierra Club, Inc., is a national organization, the mission of which is to explore, enjoy, and advocate for the environment. A substantial number of Sierra Club’s 28,000 Florida members utilize the Silver River, Silver Springs, the Ocklawaha River, and the St. Johns River for water-based recreational activities, which uses include kayaking, swimming, fishing, boating, canoeing, nature photography, and bird watching. St. Johns Riverkeeper, Inc., is one of 280 members of the worldwide Waterkeepers Alliance. Its mission is to protect, restore, and promote healthy waters of the St. Johns River, its tributaries, springs, and wetlands -- including Silver Springs, the Silver River, and the Ocklawaha River -- through citizen- based advocacy. A substantial number of St. Johns Riverkeeper’s more than 1,000 members use and enjoy the St. Johns River, the Silver River, Silver Springs, and the Ocklawaha River for boating, fishing, wildlife observation, and other water-based recreational activities. Karen Ahlers is a native of Putnam County, Florida, and lives approximately 15 miles from the Applicant’s property on which the permitted uses will be conducted. Ms. Ahlers currently uses the Ocklawaha River for canoeing, kayaking, and swimming, and enjoys birding and nature photography on and around the Silver River. Over the years, Ms. Ahlers has advocated for the restoration and protection of the Ocklawaha River, as an individual and as a past-president of the Putnam County Environmental Council. Jeri Baldwin lives on a parcel of property in the northeast corner of Marion County, approximately one mile from the Applicant’s property on which the permitted uses will be conducted. Ms. Baldwin, who was raised in the area, and whose family and she used the resources extensively in earlier years, currently uses the Ocklawaha River for boating. Florida Defenders of the Environment (FDE) is a Florida corporation, the mission of which is to conserve and protect and restore Florida's natural resources and to conduct environmental education projects. A substantial number of FDE’s 186 members, of which 29 reside in Marion County, Florida, use and enjoy Silver Springs, the Silver River, and the Ocklawaha Aquatic Preserve, and their associated watersheds in their educational and outreach activities, as well as for various recreational activities including boating, fishing, wildlife observation, and other water-based recreational activities. Sleepy Creek Lands, LLC (Sleepy Creek or Applicant), is an entity registered with the Florida Department of State to do business in the state of Florida. Sleepy Creek owns approximately 21,000 acres of land in Marion County, Florida, which includes the East Tract and the North Tract on which the activities authorized by the permits are proposed. St. Johns River Water Management District (SJRWMD or District) is a water-management district created by section 373.069(1). It has the responsibility to conserve, protect, manage, and control the water resources within its geographic boundaries. See § 373.069(2)(a), Fla. Stat. The Consumptive Use Permit The CUP is a modification and consolidation of two existing CUP permits, CUP No. 2-083-3011-7 and CUP No. 2-083- 91926-2, which authorize the withdrawal of 1.46 mgd from wells located on the East Tract. Although the existing CUP permits authorize an allocation of 1.46 mgd, actual use has historically been far less, and rarely exceeded 0.3 mgd. The proposed CUP modification will convert the authorized use of water from irrigation of 1,010 acres of sod grass on the East Tract, to supplemental irrigation of improved pasture for grass and other forage crops (approximately 97 percent of the proposed withdrawals) and cattle watering (approximately three percent of the proposed withdrawals) on the North Tract and the East Tract. An additional very small amount will be used in conjunction with the application of agricultural chemicals. CUP No. 2-083-3011-7 is due to expire in 2021. CUP No. 2-083-91926-2 is due to expire in 2024. In addition to the consolidation of the withdrawals into a single permit, the proposed agency action would extend the term of the consolidated permit to 20 years from issuance, with the submission of a compliance report due 10 years from issuance. Sleepy Creek calculated a water demand of 2.569 mgd for the production of grasses and forage crops necessary to meet the needs for grass-fed beef production, based on the expected demand in a 2-in-10 drought year. That calculation is consistent with that established in CUP Applicant’s Handbook (CUP A.H.) section 12.5.1. The calculated amount exceeds the authorized average allocation of 1.46 mgd. Mr. Jenkins testified as to the District’s understanding that the requested amount would be sufficient, since the proposed use was a “scaleable-type project,” with adjustments to cattle numbers made as necessary to meet the availability of feed. Regardless of demand, the proposed permit establishes the enforceable withdrawal limits applicable to the property. With regard to the East Tract, the proposed agency action reduces the existing 1.46 mgd allocation for that tract to a maximum allocation of 0.464 mgd, and authorizes the irrigation of 611 acres of pasture grass using existing extraction wells and six existing pivots. With regard to the North Tract, the proposed agency action authorizes the irrigation of 1,620 acres of pasture and forage grain crops using 15 center pivot systems. Extraction wells to serve the North Tract pivots will be constructed on the North Tract. The proposed North Tract withdrawal wells are further from Silver Springs than the current withdrawal locations. The proposed CUP allows Sleepy Creek to apply the allocated water as it believes to be appropriate to the management of the cattle operation. Although the East Tract is limited to a maximum of 0.464 mgd, there is no limitation on the North Tract. Thus, Sleepy Creek could choose to apply all of the 1.46 mgd on the North Tract. For that reason, the analysis of impacts from the irrigation of the North Tract has generally been based on the full 1.46 mgd allocation being drawn from and applied to the North Tract. The Environmental Resource Permit As initially proposed, the CUP had no elements that would require issuance of an ERP. However, in order to control the potential for increased runoff and nutrient loading resulting from the irrigation of the pastures, Sleepy Creek proposes to construct a stormwater management system to capture runoff from the irrigated pastures, consisting of a series of vegetated upland buffers, retention berms and redistribution swales between the pastures and downgradient wetland features. Because the retention berm and swale system triggered the permitting thresholds in rule 62-330.020(2)(d) (“a total project area of more than one acre”) and rule 62-330.020(2)(e) (“a capability of impounding more than 40 acre-feet of water”), Sleepy Creek was required to obtain an Environmental Resource Permit for its construction. Regional Geologic Features To the west of the North Tract is a geologic feature known as the Ocala Uplift or Ocala Platform, in which the limestone that comprises the Floridan aquifer system exists at or very near the land surface. Karst features, including subterranean conduits and voids that can manifest at the land surface as sinkholes, are common in the Ocala Uplift due in large part to the lack of consolidated or confining material overlaying the limestone. Water falling on the surface of such areas tends to infiltrate rapidly through the soil into the Floridan aquifer, occasionally through direct connections such as sinkholes. The lack of confinement in the Ocala Uplift results in few if any surface-water features such as wetlands, creeks, and streams. As one moves east from the Ocala Uplift, a geologic feature known as the Cody Escarpment becomes more prominent. In the Cody Escarpment, the limestone becomes increasingly overlain by sands, shell, silt, clays, and other less permeable sediments of the Hawthorn Group. The North Tract and the East Tract lie to the east of the point at which the Cody Escarpment becomes apparent. As a result, water tends to flow overland to wetlands and other surface water features. The Property The North and East Tracts are located in northern Marion County near the community of Fort McCoy. East Tract Topography and Historic Use The East Tract is located in the Daisy Creek Basin, and includes the headwaters of a small creek that drains directly to the Ocklawaha River. The historic use of the East Tract has been as a cleared 1,010-acre sod farm. The production of sod included irrigation, fertilization, and pest control. Little change in the topography, use, and appearance of the property will be apparent as a result of the permits at issue, but for the addition of grazing cattle. The current CUPs that are subject to modification in this proceeding authorize groundwater withdrawals for irrigation of the East Tract at the rate of 1.46 mgd. Since the proposed agency action has the result of reducing the maximum withdrawal from wells on the East Tract to 0.464 mgd, thus proportionately reducing the proposed impacts, there was little evidence offered to counter Sleepy Creek’s prima facie case that reasonable assurance was provided that the proposed East Tract groundwater withdrawal allocation will meet applicable CUP standards. There are no stormwater management structures to be constructed on the East Tract. Therefore, the ERP permit discussed herein is not applicable to the East Tract. North Tract Topography and Historic Use The North Tract has a generally flat topography, with elevations ranging from 45 feet to 75 feet above sea level. The land elevation is highest at the center of the North Tract, with the land sloping towards the Ocklawaha River to the east, and to several large wet prairie systems to the west. Surface water features on the North Tract include isolated, prairie, and slough-type wetlands on approximately 28 percent of the North Tract, and a network of creeks, streams, and ditches, including the headwaters of Mill Creek, a contributing tributary of the Ocklawaha River. A seasonal high groundwater elevation on the North Tract is estimated at 6 to 14 inches below ground surface. The existence of defined creeks and surface water features supports a finding that the North Tract is underlain by a relatively impermeable confining layer that impedes the flow of water from the surface and the shallow surficial aquifer to the upper Floridan and lower Floridan aquifers. If there was no confining unit, water going onto the surface of the property, either in the form of rain or irrigation water, would percolate unimpeded to the lower aquifers. Areas in the Ocala Uplift to the west of the North Tract, where the confining layer is thinner and discontiguous, contain few streams or runoff features. Historically, the North Tract was used for timber production, with limited pasture and crop lands. At the time the 7,207-acre North Tract was purchased by Sleepy Creek, land use consisted of 4,061 acres of planted pine, 1,998 acres of wetlands, 750 acres of improved pasture, 286 acres of crops, 78 acres of non-forested uplands, 20 acres of native forest, 10 acres of open water, and 4 acres of roads and facilities. Prior to the submission of the CUP and ERP applications, much of the planted pine was harvested, and the land converted to improved pasture. Areas converted to improved pasture include those proposed for irrigation, which have been developed in the circular configuration necessary for future use with center irrigation pivots. As a result of the harvesting of planted pine, and the conversion of about 345 acres of cropland and non-forested uplands to pasture and incidental uses, total acreage in pasture on the North Tract increased from 750 acres to 3,938 acres. Other improvements were constructed on the North Tract, including the cattle processing facility. Aerial photographs suggest that the conversion of the North Tract to improved pasture and infrastructure to support a cattle ranch is substantially complete. The act of converting the North Tract from a property dominated by planted pine to one dominated by improved pasture, and the change in use of the East Tract from sod farm to pasture, were agricultural activities that did not require a permit from the District. As such, there is no impropriety in considering the actual, legal use of the property in its current configuration as the existing use for which baseline conditions are to be measured. Petitioners argue that the baseline conditions should be measured against the use of the property as planted pine plantation, and that Sleepy Creek should not be allowed to “cattle-up” before submitting its permit applications, thereby allowing the baseline to be established as a higher impact use. However, the applicable rules and statutes provide no retrospective time-period for establishing the nature of a parcel of property other than that lawfully existing when the application is made. See West Coast Reg’l Water Supply Auth. v. SW Fla. Water Mgmt. Dist., Case No. 95-1520 et seq., ¶ 301 (Fla. DOAH May 29, 1997; SFWMD ) (“The baseline against which projected impacts conditions [sic] are those conditions, including previously permitted adverse impacts, which existed at the time of the filing of the renewal applications.”). The evidence and testimony in this case focused on the effects of the water allocation on the Floridan aquifer, Silver Springs, and the Silver River, and on the effects of the irrigation on water and nutrient transport from the properties. It was not directed at establishing a violation of chapter 373, the rules of the SJRWMD, or the CUP Applicant’s Handbook with regard to the use and management of the agriculturally-exempt unirrigated pastures, nor did it do so. Soil Types Soils are subject to classifications developed by the Soil Conservation Service based on their hydrologic characteristics, and are grouped into Group A, Group B, Group C, or Group D. Factors applied to determine the appropriate hydrologic soil group on a site-specific basis include depth to seasonal high saturation, the permeability rate of the most restrictive layer within a certain depth, and the depth to any impermeable layers. Group A includes the most well-drained soils, and Group D includes the most poorly-drained soils. Group D soils are those with seasonal high saturation within 24 inches of the soil surface and a higher runoff potential. The primary information used to determine the hydrologic soil groups on the North Tract was the depth to seasonal-high saturation, defined as the highest expected annual elevation of saturation in the soil. Depth to seasonal-high saturation was measured through a series of seven hand-dug and augered soil borings completed at various locations proposed for irrigation across the North Tract. In determining depth to seasonal-high saturation, the extracted soils were examined based on depth, color, texture, and other relevant characteristics. In six of the seven locations at which soil borings were conducted, a restrictive layer was identified within 36 inches of the soil surface. At one location at the northeastern corner of the North Tract, the auger hole ended at a depth of 48 inches -- the length of the auger -- at which depth there was an observable increase in clay content but not a full restrictive layer. However, while the soil assessment was ongoing, a back-hoe was in operation approximately one hundred yards north of the boring location. Observations of that excavation revealed a heavy clay layer at a depth of approximately 5 feet. In each of the locations, the depth to seasonal-high saturation was within 14 inches of the soil surface. Based on the consistent observation of seasonal-high saturation at each of the sampled locations, as well as the flat topography of the property with surface water features, the soils throughout the property, with the exception of a small area in the vicinity of Pivot 6, were determined to be in hydrologic soil Group D. Hydrogeologic Features There are generally five hydrogeologic units underlying the North Tract, those units being the surficial aquifer system, the intermediate confining unit, the upper Floridan aquifer, the middle confining unit, and the lower Floridan aquifer. In areas in which a confining layer is present, water falling on the surface of the land flows over the surface of the land or across the top of the confining layer. A surficial aquifer, with a relatively high perched water table, is created by the confinement and separation of surface waters from the upper strata of the Floridan aquifer. Surface waters are also collected in or conveyed by various surface water features, including perched wetlands, creeks, and streams. The preponderance of the evidence adduced at the final hearing demonstrates that the surficial aquifer exists on the property to a depth of up to 20 feet below the land surface (bls). Beneath the surficial aquifer is an intermediate confining unit of dense clay interspersed with beds of sand and calcareous clays that exists to a depth of up to 100 feet bls. The clay material observed on the North Tract is known as massive or structureless. Such clays are restrictive with very low levels of hydraulic conductivity, and are not conducive to development of preferential flow paths to the surficial or lower aquifers. The intermediate confining unit beneath the North Tract restricts the exchange of groundwater from the surficial aquifer to the upper Floridan aquifer. The upper Floridan aquifer begins at a depth of approximately 100 feet bls, and extends to a depth of approximately 340 feet bls. At about 340 feet bls, the upper Floridan aquifer transitions to the middle confining unit, which consists of finely grained, denser material that separates the interchange of water between the upper Floridan aquifer and the lower Floridan aquifer. Karst Features Karst features form as a result of water moving through rock that comprises the aquifer, primarily limestone, dissolving and forming conduits in the rock. Karst areas present a challenging environment to simulate through modeling. Models assume the subsurface to be a relatively uniform “sand box” through which it is easier to simulate groundwater flow. However, if the subsurface contains conduits, it becomes more difficult to simulate the preferential flows and their effect on groundwater flow paths and travel times. The District has designated parts of western Alachua County and western Marion County as a Sensitive Karst Area Basin. A Sensitive Karst Area is a location in which the porous limestone of the Floridan aquifer occurs within 20 feet of the land surface, and in which there is 10 to 20 inches of annual recharge to the Floridan aquifer. The designation of an area as being within the Sensitive Karst Area Basin does not demonstrate that it does, or does not, have subsurface features that are karstic in nature, or that would provide a connection between the surficial aquifer and the Floridan aquifer. The western portion of the North Tract is within the Sensitive Karst Area Basin. The two intensive-use areas on the North Tract that have associated stormwater facilities -- the cattle unloading area and the processing facility -- are outside of the Sensitive Karst Area Basin. The evidence was persuasive that karst features are more prominent to the west of the North Tract. In order to evaluate the presence of karst features on the North Tract, Mr. Andreyev performed a “desktop-type evaluation,” with a minimal field survey. The desktop review included a review of aerial photographs and an investigation of available data, including the Florida Geological Survey database of sinkhole occurrence in the area. The aerial photographs showed circular depressions suggestive of karst activity west and southwest of the North Tract, but no such depressions on the North Tract. Soil borings taken on the North Tract indicated the presence of layers of clayey sand, clays, and silts at a depth of 70 to 80 feet. Well-drilling logs taken during the development of the wells used for an aquifer performance test on the North Tract showed the limestone of the Floridan aquifer starting at a depth below ground surface of 70 to 80 feet. Other boring data generated on the North Tract suggests that there is greater than 100 feet of clay and sandy clay overburden above the Floridan aquifer on and in the vicinity of the North Tract. Regardless of site-specific differences, the observed confining layer separating the surficial aquifer from the Floridan aquifer is substantial, and not indicative of a karst environment. Aquifer performance tests performed on the North Tract were consistent in showing that drawdown in the surficial aquifer from the tests was minimal to non-detectable, which is strong evidence of an intact and low-permeability confining layer. The presence of well-developed drainage features on the North Tract is further evidence of a unit of confinement that is restricting water from going deeper into the subsurface, and forcing it to runoff to low-lying surface water features. Petitioners’ witnesses did not perform any site- specific analysis of karst features on or around the Sleepy Creek property. Their understanding of the nature of the karst systems in the region was described as “hypothetical or [] conceptual.” Dr. Kincaid admitted that he knew of no conduits on or adjacent to the North Tract. As a result of the data collected from the North Tract, Mr. Hearn opined that the potential for karst features on the property that provide an opening to the upper Floridan aquifer “is extremely remote.” Mr. Hearn’s opinion is consistent with the preponderance of the evidence in this case, and is accepted. In the event a surface karst feature were to manifest itself, Sleepy Creek has proposed that the surface feature be filled and plugged to reestablish the integrity of the confining layer. More to the point, the development of a surficial karst feature in an area influenced by irrigation would be sufficient grounds for the SJRWMD to reevaluate and modify the CUP to account for any changed conditions affecting the assumptions and bases for issuance of the CUP. Silver Springs, the Silver River, and the Ocklawaha River The primary, almost exclusive concern of Petitioners was the effect of the modified CUP and the nutrients from the proposed cattle ranch on Silver Springs, the Silver River, and the Ocklawaha River. Silver Springs Silver Springs has long been a well-known attraction in Florida. It is located just to the east of Ocala, Florida. Many of the speakers at the public comment period of this proceeding spoke fondly of having frequented Silver Springs over the years, enjoying its crystal clear waters through famous glass-bottomed boats. For most of its recorded history, Silver Springs was the largest spring by volume in Florida. Beginning in the 1970s, it began to lose its advantage, and by the year 2000, Rainbow Springs, located in southwestern Marion County, surpassed Silver Springs as the state’s largest spring. Silver Springs exists at the top of the potentiometric surface of the Floridan aquifer. Being at the “top of the mountain,” when water levels in the Floridan aquifer decline, groundwater flow favors the lower elevation springs. Thus, surrounding springshed boundaries expand to take more water to maintain their baseflows, at the expense of the Silver Springs springshed, which contracts. Rainbow Springs shares an overlapping springshed with Silver Springs. The analogy used by Dr. Knight was of the aquifer as a bucket with holes at different levels, and with the Silver Springs “hole” near the top of the bucket. When the water level in the bucket is high, water will flow from the top hole. As the water level drops below that hole, it will preferentially flow from the lower holes. Rainbow Springs has a vent or outlet from the aquifer, that is 10 feet lower in elevation than that of Silver Springs. Coastal springs are lower still. Thus, as groundwater levels decline, the lower springs “pirate flow” from the upper springs. Since the first major studies of Silver Springs were conducted in the 1950s, the ecosystem of Silver Springs has undergone changes. The water clarity, though still high as compared to other springs, has been reduced by 10 to 15 percent. Since the 1950s, macrophytic plants, i.e., rooted plants with seeds and flowers, have declined in population, while epiphytic and benthic algae have increased. Those plants are sensitive to increases in nitrogen in the water. Thus, Dr. Knight’s opinion that increases in nitrogen emerging from Silver Springs, calculated to have risen from just over 0.4 mg/l in the 1950s, to 1.1 mg/l in 2004, and to up to 1.5 mg/l at present,1/ have caused the observed vegetative changes is accepted. Silver River Silver Springs forms the headwaters for the Silver River, a spring run 5 1/2 miles in length, at which point it becomes a primary input to the Ocklawaha River. Issues of water clarity and alteration of the vegetative regime that exist at Silver Springs are also evident in the Silver River. In addition, the reduction in flow allows for more tannic water to enter the river, further reducing clarity. Dr. Dunn recognized the vegetative changes in the river, and opined that the “hydraulic roughness” caused by the increase in vegetation is likely creating a spring pool backwater at Silver Springs, thereby suppressing some of the flow from the spring. The Silver River has been designated as an Outstanding Florida Water. There are currently no Minimum Flows and Levels established by the District for the Silver River. Ocklawaha River The Ocklawaha River originates near Leesburg, Florida, at the Harris Chain of Lakes, and runs northward past Silver Springs. The Silver River is a major contributor to the flow of the Ocklawaha River. Due to the contribution of the Silver River and other spring-fed tributaries, the Ocklawaha River can take on the appearance of a spring run during periods of low rainfall. Historically, the Ocklawaha River flowed unimpeded to its confluence with the St. Johns River in the vicinity of Palatka, Florida. In the 1960s, as part of the Cross-Florida Barge Canal project, the Rodman Dam was constructed across the Ocklawaha River north of the Sleepy Creek property, creating a large reservoir known as the Rodman Pool. Dr. Knight testified convincingly that the Rodman Dam and Pool have altered the Ocklawaha River ecosystem, precipitating a decline in migratory fish populations and an increase in filamentous algae. At the point at which the Ocklawaha River flows past the Sleepy Creek property, it retains its free-flowing characteristics. Mill Creek, which has its headwaters on the North Tract, is a tributary of the Ocklawaha River. The Ocklawaha River, from the Eureka Dam south, has been designated as an Outstanding Florida Water. However, the Ocklawaha River at the point at which Mill Creek or other potential surface water discharges from the Sleepy Creek property might enter the river are not included in the Outstanding Florida Water designation. There are currently no Minimum Flows and Levels established by the District for the Ocklawaha River. The Silver Springs Springshed A springshed is that area from which a spring draws water. Unlike a surface watershed boundary, which is fixed based on land features, contours, and elevations, a springshed boundary is flexible, and changes depending on a number of factors, including rainfall. As to Silver Springs, its springshed is largest during periods of more abundant rainfall when the aquifer is replenished, and smaller during drier periods when groundwater levels are down, and water moves preferentially to springs and discharge points that are lower in elevation. The evidence in this case was conflicting as to whether the North Tract is in or out of the Silver Springs springshed boundary. Dr. Kincaid indicated that under some of the springshed delineations, part of the North Tract was out of the springshed, but over the total period of record, it is within the springshed. Thus, it was Dr. Kincaid’s opinion that withdrawals anywhere within the region will preferentially impact Silver Springs, though he admitted that he did not have the ability to quantify his opinion. Dr. Knight testified that the North Tract is within the Silver Springs “maximum extent” springshed at least part of the time, if not all the time. He did not opine as to the period of time in which the Silver Springs springshed was at its maximum extent. Dr. Bottcher testified that the North Tract is not within the Silver Springs springshed because there is a piezometric rise between North Tract and Silver Springs. Thus, in his opinion, withdrawals at the North Tract would not be withdrawing water going to Silver Springs. Dr. Dunn agreed that the North Tract is on the groundwater divide for Silver Springs. In his view, the North Tract is sometimes in, and sometimes out of the springshed depending on the potentiometric surface. In his opinion, the greater probability is that the North Tract is more often outside of the Silver Springs springshed, with seasonal and year—to—year variation. Dr. Dunn’s opinion provides the most credible explanation of the extent to which the North Tract sits atop that portion of the lower Floridan aquifer that feeds to Silver Springs. Thus, it is found that the groundwater divide exists to the south of the North Tract for a majority of the time, and water entering the Floridan aquifer from the North Tract will, more often than not, flow away from Silver Springs. Silver Springs Flow Volume The Silver Springs daily water discharge has been monitored and recorded since 1932. Over the longest part of the period of record, up to the 1960s, flows at Silver Springs averaged about 800 cubic feet per second (cfs). Through 1989, there was a reasonable regression between rainfall and springflow, based on average rainfalls. The long-term average rainfall in Ocala was around 50 inches per year, and long-term springflow was about 800 cfs, with deviations from average generally consistent with one another. Between 1990 and 1999, the relationship between rainfall and springflow declined by about 80 cubic feet per second. Thus, with average rainfall of 50 inches per year, the average springflow was reduced to about 720 cfs. From 2000 to 2009, there was an additional decline, such that the total cumulative decline for the 20-year period through 2009 was 250 cfs. Dr. Dunn agreed with Dr. Knight that after 2000, there was an abrupt and persistent reduction in flow of about 165 cfs. However, Dr. Dunn did not believe the post-2000 flow reduction could be explained by rainfall directly, although average rainfall was less than normal. Likewise, groundwater withdrawals did not offer an adequate explanation. Dr. Dunn described a natural 30-year cycle of wetter and drier periods known as the Atlantic Multidecadal Oscillation (AMO) that has manifested itself over the area for the period of record. From the 1940s up through 1970, the area experienced an AMO wet cycle with generally higher than normal rainfall at the Ocala rain station. For the next 30-year period, from 1970 up to 2000, the Ocala area ranged from a little bit drier to some years in which it was very, very dry. Dr. Dunn attributed the 80 cfs decline in Silver Springs flow recorded in the 1990s to that lower rainfall cycle. After 2000, when the next AMO cycle would be expected to build up, as it did post—1940, it did not happen. Rather, there was a particularly dry period around 2000 that Dr. Dunn believes to have had a dramatic effect on the lack of recovery in the post-2000 flows in the Silver River. According to Mr. Jenkins, that period of deficient rainfall extended through 2010. Around the year 2001, the relationship between rainfall and flow changed such that for a given amount of rainfall, there was less flow in the Silver River, with flow dropping to as low as 535 cfs after 2001. It is that reduction in flow that Dr. Knight has attributed to groundwater withdrawals. It should be noted that the observed flow of Silver Springs that formed the 1995 baseline conditions for the North Central Florida groundwater model that will be discussed herein was approximately 706 cfs. At the time of the final hearing in August 2014, flow at Silver Springs was 675 cfs. The reason offered for the apparent partial recovery was higher levels of rainfall, though the issue was not explored in depth. For the ten-year period centered on the year 2000, local water use within Marion and Alachua County, closer to Silver Springs, changed little -- around one percent per year. From a regional perspective, groundwater use declined at about one percent per year for the period from 1990 to 2010. The figures prepared by Dr. Knight demonstrate that the Sleepy Creek project area is in an area that has a very low density of consumptive use permits as compared to areas adjacent to Silver Springs and more clearly in the Silver Springs springshed. In Dr. Dunn’s opinion, there were no significant changes in groundwater use either locally or regionally that would account for the flow reduction in Silver Springs from 1990 to 2010. In that regard, the environmental report prepared by Dr. Dunn and submitted with the CUP modification application estimated that groundwater withdrawals accounted for a reduction in flow at Silver Springs of approximately 20 cfs as measured against the period of record up to the year 2000, with most of that reduction attributable to population growth in Marion County. In the March 2014, environmental impacts report, Dr. Dunn described reductions in the stream flow of not only the Silver River, but of other tributaries of the lower Ocklawaha River, including the upper Ocklawaha River at Moss Bluff and Orange Creek. However, an evaluation of the Ocklawaha River water balance revealed there to be additional flow of approximately 50 cfs coming into the Ocklawaha River at other stations. Dr. Dunn suggested that changes to the vent characteristics of Silver Springs, and the backwater effects of increased vegetation in the Silver River, have resulted in a redistribution of pressure to other smaller springs that discharge to the Ocklawaha River, accounting for a portion of the diminished flow at Silver Springs. The Proposed Cattle Operation Virtually all beef cattle raised in Florida, upon reaching a weight of approximately 875 pounds, are shipped to Texas or Kansas to be fattened on grain to the final body weight of approximately 1,150 pounds, whereupon they are slaughtered and processed. The United States Department of Agriculture has a certification for grass—fed beef which requires that, after an animal is weaned, it can only be fed on green forage crops, including grasses, and on corn and grains that are cut green and before they set seed. The forage crops may be grazed or put into hay or silage and fed when grass and forage is dormant. The benefit of grass feeding is that a higher quality meat is produced, with a corresponding higher market value. Sleepy Creek plans to develop the property as a grass- fed beef production ranch, with pastures and related loading/unloading and slaughter/processing facilities where calves can be fattened on grass and green grain crops to a standard slaughter weight, and then slaughtered and processed locally. By so doing, Sleepy Creek expects to save the transportation and energy costs of shipping calves to the Midwest, and to generate jobs and revenues by employing local people to manage, finish, and process the cattle. As they currently exist, pastures proposed for irrigation have been cleared and seeded, and have “fairly good grass production.” The purpose of the irrigation is to enhance the production and quality of the grass in order to maintain the quality and reliability of feed necessary for the production of grass-fed beef. East Tract Cattle Operation The East Tract is 1,242 acres in size, substantially all of which was previously cleared, irrigated, and used for sod production. The proposed CUP permit authorizes the irrigation of 611 acres of pasture under six existing center pivots. The remaining 631 acres will be used as improved, but unirrigated, pasture. Under the proposed permit, a maximum of 1,207 cattle would be managed on the East Tract. Of that number, 707 cattle would be grazed on the irrigated paddocks, and 500 cattle would be grazed on the unirrigated improved pastures. If the decision is made to forego irrigation on the East Tract, with the water allocation being used on the North Tract or not at all, the number of cattle grazed on the six center pivot pastures would be decreased from 707 cattle to 484 cattle. The historic use of the East Tract as a sod farm resulted in high phosphorus levels in the soil from fertilization, which has made its way to Daisy Creek. Sleepy Creek has proposed a cattle density substantially below that allowed by application of the formulae in the Nutrient Management Plan in order to “mine” the phosphorus levels in the soil over time. North Tract Cattle Operation The larger North Tract includes most of the “new” ranch activities, having no previous irrigation, and having been put to primarily silvicultural use with limited pasture prior to its acquisition by Sleepy Creek. The ranch’s more intensive uses, i.e., the unloading corrals and the slaughter house, are located on the North Tract. The North Tract is 7,207 acres in size. Of that, 1,656 acres are proposed for irrigation by means of 15 center- pivot irrigation systems. In addition to the proposed irrigated pastures, the North Tract includes 2,382 acres of unirrigated improved pasture, of which approximately 10 percent is wooded. Under the proposed permit, a maximum of 6,371 cattle would be managed on the North Tract. Of that number, 3,497 cattle would be grazed on the irrigated paddocks (roughly 2.2 head of cattle per acre), and 2,374 cattle would graze on the improved pastures (up to 1.1 head of cattle per acre). The higher cattle density in the irrigated pastures can be maintained due to the higher quality grass produced as a result of irrigation. The remaining 500 cattle would be held temporarily in high-concentration corrals, either after offloading or while awaiting slaughter. On average, there will be fewer than 250 head of cattle staged in those high-concentration corrals at any one time. In the absence of irrigation, the improved pasture on the North Tract could sustain about 4,585 cattle. Nutrient Management Plan, Water Conservation Plan, and BMPs The CUP and ERP applications find much of their support in the implementation of the Nutrient Management Plan (NMP), the Water Conservation Plan, and Best Management Practices (BMPs). The NMP sets forth information designed to govern the day to day operations of the ranch. Those elements of the NMP that were the subject of substantive testimony and evidence at the hearing are discussed herein. Those elements not discussed herein are found to have been supported by Sleepy Creek’s prima facie case, without a preponderance of competent and substantial evidence to the contrary. The NMP includes a herd management plan, which describes rotational grazing and the movement of cattle from paddock to paddock, and establishes animal densities designed to maintain a balance of nutrients on the paddocks, and to prevent overgrazing. The NMP establishes fertilization practices, with the application of fertilizer based on crop tissue analysis to determine need and amount. Thus, the application of nitrogen- based fertilizer is restricted to that capable of ready uptake by the grasses and forage crops, limiting the amount of excess nitrogen that might run off of the pastures or infiltrate past the root zone. The NMP establishes operation and maintenance plans that incorporate maintenance and calibration of equipment, and management of high-use areas. The NMP requires that records be kept of, among other things, soil testing, nutrient application, herd rotation, application of irrigation water, and laboratory testing. The irrigation plan describes the manner and schedule for the application of water during each irrigation cycle. Irrigation schedules for grazed and cropped scenarios vary from pivot to pivot based primarily on soil type. The center pivots proposed for use employ high-efficiency drop irrigation heads, resulting in an 85 percent system efficiency factor, meaning that there is an expected evaporative loss of 15 percent of the water before it becomes available as water in the soil. That level of efficiency is greater than the system efficiency factor of 80 percent established in CUP A.H. section 12.5.2. Other features of the irrigation plan include the employment of an irrigation manager, installation of an on-site weather station, and cumulative tracking of rain and evapotranspiration with periodic verification of soil moisture conditions. The purpose of the water conservation practices is to avoid over application of water, limiting over-saturation and runoff from the irrigated pastures. Sleepy Creek has entered into a Notice of Intent to Implement Water Quality BMPs with the Florida Department of Agriculture and Consumer Services which is incorporated in the NMP and which requires the implementation of Best Management Practices.2/ Dr. Bottcher testified that implementation and compliance with the Water Quality Best Management Practices manual creates a presumption of compliance with water quality standards. His testimony in that regard is consistent with Department of Agriculture and Consumer Services rule 5M-11.003 (“implementation, in accordance with adopted rules, of BMPs that have been verified by the Florida Department of Environmental Protection as effective in reducing target pollutants provides a presumption of compliance with state water quality standards.”). Rotational Grazing Rotational grazing is a practice by which cattle are allowed to graze a pasture for a limited period of time, after which they are “rotated” to a different pasture. The 1,656 acres proposed for irrigation on the North Tract are to be divided into 15 center-pivot pastures. Each individual pasture will have 10 fenced paddocks. The 611 acres of irrigated pasture on the East Tract are divided into 6 center-pivot pastures. The outer fence for each irrigated pasture is to be a permanent “hard” fence. Separating the internal paddocks will be electric fences that can be lowered to allow cattle to move from paddock to paddock, and then raised after they have moved to the new paddock. The NMP for the North Tract provides that cattle are to be brought into individual irrigated pastures as a single herd of approximately 190 cattle and placed into one of the ten paddocks. They will be moved every one to three days to a new paddock, based upon growing conditions and the reduction in grass height resulting from grazing. In this way, the cattle are rotated within the irrigated pasture, with each paddock being used for one to three days, and then rested until each of the other paddocks have been used, whereupon it will again be used in the rotation. The East Tract NMP generally provides for rotation based on the height of the pasture grasses, but is designed to provide a uniform average of cattle per acre per year. Due to the desire to “mine” phosphorus deposited during the years of operation of the East Tract as a sod farm, the density of cattle on the irrigated East Tract pastures is about 30 percent less than that proposed for the North Tract. The East Tract NMP calls for a routine pasture rest period of 15 to 30 days. Unlike dairy farm pastures, where dairy cows traverse a fixed path to the milking barn several times a day, there will be minimal “travel lanes” within the pastures or between paddocks. There will be no travel lanes through wetlands. If nitrogen-based fertilizer is needed, based upon tissue analysis of the grass, fertilizer is proposed for application immediately after a paddock is vacated by the herd. By so doing, the grass within each paddock will have a sufficient period to grow and “flush up” without grazing or traffic, which results in a high—quality grass when the cattle come back around to feed. Sleepy Creek proposes that rotational grazing is to be practiced on improved pastures and irrigated pastures alike. The rotational practices on the improved East Tract and North Tract pastures are generally similar to those practiced on the irrigated pastures. The paddocks will have permanent watering troughs, with one trough serving two adjacent paddocks. The troughs will be raised to prevent “boggy areas” from forming around the trough. Since the area around the troughs will be of a higher use, Sleepy Creek proposes to periodically remove accumulated manure, and re-grade if necessary. Other cattle support items, including feed bunkers and shade structures are portable and can be moved as conditions demand. Forage Crop Production The primary forage crop on the irrigated pastures is to be Bermuda grass. Bermuda grass or other grass types tolerant of drier conditions will be used in unirrigated pastures. During the winter, when Bermuda grass stops growing, Sleepy Creek will overseed the North Tract pastures with ryegrass or other winter crops. Due to the limitation on irrigation water, the East Tract NMP calls for no over-seeding for production of winter crops. Crops do not grow uniformly during the course of a year. Rather, there are periods during which there are excess crops, and periods during which the crops are not growing enough to keep up with the needs of the cattle. During periods of excess, Sleepy Creek will cut those crops and store them as haylage to be fed to the cattle during lower growth periods. The North Tract management plan allows Sleepy Creek to dedicate one or more irrigated pastures for the exclusive production of haylage. If that option is used, cattle numbers will be reduced in proportion to the number of pastures dedicated to haylage production. As a result of the limit on irrigation, the East Tract NMP does not recommend growing supplemental feed on dedicated irrigation pivot pastures. Direct Wetland Impacts Approximately 100 acres proposed for irrigation are wetlands or wetland buffer. Those areas are predominantly isolated wetlands, though some have surface water connections to Mill Creek, a water of the state. Trees will be cut in the wetlands to allow the pivot to pass overhead. Tree cutting is an exempt agricultural activity that does not require a permit. There was no persuasive evidence that cutting trees will alter the fundamental benefit of the wetlands or damage water resources of the District. The wetlands and wetland buffer will be subject to the same watering and fertigation regimen as the irrigated pastures. The application of water to wetlands, done concurrently with the application of water to the pastures, will occur during periods in which the pasture soils are dry. The incidental application of water to the wetlands during dry periods will serve to maintain hydration of the wetlands, which is considered to be a benefit. Fertilizers will be applied through the irrigation arms, a process known as fertigation. Petitioners asserted that the application of fertilizer onto the wetlands beneath the pivot arms could result in some adverse effects to the wetlands. However, Petitioners did not quantify to what extent the wetlands might be affected, or otherwise describe the potential effects. Fertigation of the wetlands will promote the growth of wetland plants. Nitrogen applied through fertigation will be taken up by plants, or will be subject to denitrification -- a process discussed in greater detail herein -- in the anaerobic wetland soils. The preponderance of the evidence indicated that enhanced wetland plant growth would not rise to a level of concern. Since most of the affected wetlands are isolated wetlands, there is expected to be little or no discharge of nutrients from the wetlands. Even as to those wetlands that have a surface water connection, most, if not all of the additional nitrogen applied through fertigation will be accounted for by the combined effect of plant uptake and denitrification. Larger wetland areas within an irrigated pasture will be fenced at the buffer line to prevent cattle from entering. The NMP provided a blow-up of the proposed fencing related to a larger wetland on Pivot 8. Although other figures are not to the same scale, it appears that larger wetlands associated with Pivots 1, 2, 3, and 12 will be similarly fenced. Cattle would be allowed to go into the smaller, isolated wetlands. Cattle going into wetlands do not necessarily damage the wetlands. Any damage that may occur is a function of density, duration, and the number of cattle. The only direct evidence of potential damage to wetlands was the statement that “[i]f you have 6,371 [cattle] go into a wetland, there may be impacts.” The NMP provides that pasture use will be limited to herds of approximately 190 cattle, which will be rotated from paddock to paddock every two to three days, and which will allow for “rest” periods of approximately 20 days. There will be no travel lanes through any wetland. Thus, there is no evidence to support a finding that the cattle at the density, duration, and number proposed will cause direct adverse effects to wetlands on the property. High Concentration Areas Cattle brought to the facility are to be unloaded from trucks and temporarily corralled for inspection. For that period, the cattle will be tightly confined. Cattle that have reached their slaughter weight will be temporarily held in corrals associated with the processing plant. The stormwater retention ponds used to capture and store runoff from the offloading corral and the processing plant holding corral are part of a normal and customary agricultural activity, and are not part of the applications and approvals that are at issue in this proceeding. The retention ponds associated with the high-intensity areas do not require permits because they do not exceed one acre in size or impound more than 40 acre-feet of water. Nonetheless, issues related to the retention ponds were addressed by Petitioners and Sleepy Creek, and warrant discussion here. The retention ponds are designed to capture 100 percent of the runoff and entrained nutrients from the high concentration areas for a minimum of a 24—hour/25—year storm event. If rainfall occurs in excess of the designed storm, the design is such that upon reaching capacity, only new surface water coming to the retention pond will be discharged, and not that containing high concentrations of nutrients from the initial flush of stormwater runoff. Unlike the stormwater retention berms for the pastures, which are to be constructed from the first nine inches of permeable topsoil on the property, the corral retention ponds are to be excavated to a depth of six feet which, based on soil borings in the vicinity, will leave a minimum of two to four feet of clay beneath the retention ponds. In short, the excavation will penetrate into the clay layer underlying the pond sites, but will not penetrate through that layer. The excavated clay will be used to form the side slopes of the ponds, lining the permeable surficial layer and generally making the ponds impermeable. Organic materials entering the retention ponds will form an additional seal. An organic seal is important in areas in which retention ponds are constructed in sandy soil conditions. Organic sealing is less important in this case, where clay forms the barrier preventing nutrients from entering the surficial aquifer. Although the organic material is subject to periodic removal, the clay layer will remain to provide the impermeable barrier necessary to prevent leakage from the ponds. Dr. Bottcher testified that if, during excavation of the ponds, it was found that the remaining in-situ clay layer was too thin, Sleepy Creek would implement the standard practice of bringing additional clay to the site to ensure adequate thickness of the liner. Nutrient Balance The goal of the NMP is to create a balance of nutrients being applied to and taken up from the property. Nitrogen and phosphorus are the nutrients of primary concern, and are those for which specific management standards are proposed. Nutrient inputs to the NMP consist generally of deposition of cattle manure (which includes solid manure and urine), recycling of plant material and roots from the previous growing season, and application of supplemental fertilizer. Nutrient outputs to the NMP consist generally of volatization of ammonia to the atmosphere, uptake and utilization of the nutrients by the grass and crops, weight gain of the cattle, and absorption and denitrification of the nutrients in the soil. The NMP, and the various models discussed herein, average the grass and forage crop uptake and the manure deposition to match that of a 1,013 pound animal. That average weight takes into account the fact that cattle on the property will range from calf weight of approximately 850 pounds, to slaughter weight of 1150 pounds. Nutrients that are not accounted for in the balance, e.g., those that become entrained in stormwater or that pass through the plant root zone without being taken up, are subject to runoff to surface waters or discharge to groundwater. Generally, phosphorus not taken up by crops remains immobile in the soil. Unless there is a potential for runoff to surface waters, the nutrient balance is limited by the amount of nitrogen that can be taken up by the crops. Due to the composition of the soils on the property, the high water table, and the relatively shallow confining layer, there is a potential for surface runoff. Thus, the NMP was developed using phosphorus as the limiting nutrient, which results in nutrient application being limited by the “P-index.” A total of 108 pounds of phosphorus per acre/per year can be taken up and used by the irrigated pasture grasses and forage crops. Therefore, the total number of cattle that can be supported on the irrigated pastures is that which, as a herd, will deposit an average of 108 pounds of phosphorus per year over the irrigated acreage. Therefore, Sleepy Creek has proposed a herd size and density based on calculations demonstrating that the total phosphorus contained in the waste excreted by the cattle equals the amount taken up by the crops. A herd producing 108 pounds per acre per year of phosphorus is calculated to produce 147 pounds of nitrogen per acre per year. The Bermuda grass and forage crops proposed for the irrigated fields require 420 pounds of nitrogen per acre per year. As a result of the nitrogen deficiency, additional nitrogen-based fertilizer to make up the shortfall is required to maintain the crops. Since phosphorus needs are accounted for by animal deposition, the fertilizer will have no phosphorus. The NMP requires routine soil and plant tissue tests to determine the amount of nitrogen fertilizer needed. By basing the application of nitrogen on measured rather than calculated needs, variations in inputs, including plant decomposition and atmospheric deposition, and outputs, including those affected by weather, can be accounted for, bringing the full nutrient balance into consideration. The numeric values for crop uptakes, manure deposition, and other estimates upon which the NMP was developed were based upon literature, values, and research performed and published by the University of Florida and the Natural Resource Conservation Service. Dr. Bottcher testified convincingly that the use of such values is a proven and reliable method of developing a balance for the operation of similar agricultural operations. A primary criticism of the NMP was its expressed intent to “reduce” or “minimize” the transport of nutrients to surface waters and groundwater, rather than to “negate” or “prevent” such transport. Petitioners argue that complete prevention of the transport of nutrients from the property is necessary to meet the standards necessary for issuance of the CUP and ERP. Mr. Drummond went into some detail regarding the total mass of nutrients expected to be deposited onto the ground from the cattle, exclusive of fertilizer application. In the course of his testimony, he suggested that the majority of the nutrients deposited on the land surface “are going to make it to the surficial aquifer and then be carried either to the Floridan or laterally with the groundwater flow.” However, Mr. Drummond performed no analysis on the fate of nitrogen through uptake by crops, volatization, or soil treatment, and did not quantify the infiltration of nitrogen to groundwater. Furthermore, he was not able to provide any quantifiable estimate on any effect of nutrients on Mill Creek, the Ocklawaha River, or Silver Springs. In light of the effectiveness of the nutrient balance and other elements of the NMP, along with the retention berm system that will be discussed herein, Mr. Drummond’s assessment of the nutrients that might be expected to impact water resources of the District is contrary to the greater weight of the evidence. Mr. Drummond’s testimony also runs counter to that of Dr. Kincaid, who performed a particle track analysis of the fate of water recharge from the North Tract. In short, Dr. Kincaid calculated that of the water that makes it as recharge from the North Tract to the surficial aquifer, less than one percent is expected to make its way to the upper Floridan aquifer, with that portion originating from the vicinity of Pivot 6. Recharge from the other 14 irrigated pastures was ultimately accounted for by evapotranspiration or emerged at the surface and found its way to Mill Creek. The preponderance of the competent, substantial evidence adduced at the final hearing supports the effectiveness of the NMPs for the North Tract and East Tract at managing the application and use of nutrients on the property, and minimizing the transport of nutrients to surface water and groundwater resources of the District. North Central Florida Model All of the experts involved in this proceeding agreed that the use of groundwater models is necessary to simulate what might occur below the surface of the ground. Models represent complex systems by applying data from known conditions and impacts measured over a period of years to simulate the effects of new conditions. Models are imperfect, but are the best means of predicting the effects of stresses on complex and unseen subsurface systems. The North Central Florida (NCF) model is used to simulate impacts of water withdrawals on local and regional groundwater levels and flows. The NCF model simulates the surficial aquifer, the upper Floridan aquifer, and the lower Floridan aquifer. Those aquifers are separated from one another by relatively impervious confining units. The intermediate confining unit separates the surficial aquifer from the upper Floridan aquifer. The intermediate confining unit is not present in all locations simulated by the NCF model. However, the evidence is persuasive that the intermediate confining unit is continuous at the North Tract, and serves to effectively isolate the surficial aquifer from the upper Floridan aquifer. The NCF model is not a perfect depiction of what exists under the land surface of the North Tract or elsewhere. It was, however, acknowledged by the testifying experts in this case, despite disagreements as to the extent of error inherent in the model, to be the best available tool for calculating the effects of withdrawals of water within the boundary of the model. The NCF model was developed and calibrated over a period of years, is updated routinely as data becomes available, and has undergone peer review. Aquifer Performance Tests In order to gather site-specific data regarding the characteristics of the aquifer beneath the Sleepy Creek property, a series of three aquifer performance tests (APTs) was conducted on the North Tract. The first two tests were performed by Sleepy Creek, and the third by the District. An APT serves to induce stress on the aquifer by pumping from a well at a high rate. By observing changes in groundwater levels in observation wells, which can be at varying distances from the extraction well, one can extrapolate the nature of the subsurface. In addition, well-completion reports for the various withdrawal and observation wells provide actual data regarding the composition of subsurface soils, clays, and features of the property. The APT is particularly useful in evaluating the ability of the aquifer to produce water, and in calculating the transmissivity of the aquifer. Transmissivity is a measure of the rate at which a substance passes through a medium and, as relevant to this case, measures how groundwater flows through an aquifer. The APTs demonstrated that the Floridan aquifer is capable of producing water at the rate requested. The APT drawdown contour measured in the upper Floridan aquifer was greater than that predicted from a simple run of the NCF model, but the lateral extent of the drawdown was less than predicted. The most reasonable conclusion to be drawn from the combination of greater than expected drawdown in the upper Floridan aquifer with less than expected extent is that the transmissivity of the aquifer beneath the North Tract is lower than the NCF model assumptions. The conclusion that the transmissivity of the aquifer at the North Tract is lower than previously estimated means that impacts from groundwater extraction would tend to be more vertical than horizontal, i.e., the drawdown would be greater, but would be more localized. As such, for areas of lower than estimated transmissivity, modeling would over-estimate off-site impacts from the extraction. NCF Modeling Scenarios The initial NCF modeling runs were based on an assumed withdrawal of 2.39 mgd, an earlier -- though withdrawn - - proposal. The evidence suggests that the simulated well placement for the 2.39 mgd model run was entirely on the North Tract. Thus, the results of the model based on that withdrawal have some limited relevance, especially given that the proposed CUP allows for all of the requested 1.46 mgd of water to be withdrawn from North Tract wells at the option of Sleepy Creek, but will over-predict impacts from the permitted rate of withdrawal. A factor that was suggested as causing a further over-prediction of drawdown in the 2.39 mgd model run was the decision, made at the request of the District, to exclude the input of data of additional recharge to the surficial aquifer, wetlands and surface waters from the irrigation, and the resulting diminution in soil storage capacity. Although there is some merit to the suggestion that omitting recharge made the model results “excessively conservative,” the addition of recharge to the model would not substantially alter the predicted impacts. A model run was subsequently performed based on a presumed withdrawal of 1.54 mgd, a rate that remains slightly more than, but still representative of, the requested amount of 1.46 mgd. The 1.54 mgd model run included an input for irrigation recharge. The simulated extraction points were placed on the East Tract and North Tract in the general configuration as requested in the CUP application. The NCF is designed to model the impacts of a withdrawal based upon various scenarios, identified at the hearing as Scenarios A, B, C, and D. Scenario A is the baseline condition for the NCF model, and represents the impacts of all legal users of water at their estimated actual flow rates as they existed in 1995. Scenario B is all existing users, not including the applicant, at end-of-permit allocations. Scenario C is all existing users, including the applicant, at current end-of-permit allocations. Scenario D is all permittees at full allocation, except the applicant which is modeled at the requested (i.e., new or modified) end-of-permit allocation. To simulate the effects of the CUP modification, simulations were performed on scenarios A, C, and D. In order to measure the specific impact of the modification of the CUP, the Scenario C impacts to the surficial, upper Floridan, and lower Floridan aquifers were compared with the Scenario D impacts to those aquifers. In order to measure the cumulative impact of the CUP, the Scenario A actual-use baseline condition was compared to the Scenario D condition which predicts the impacts of all permitted users, including the applicant, pumping at full end-of-permit allocations. The results of the NCF modeling indicate the following: 2.39 mgd - Specific Impact The surficial aquifer drawdown from the simulated 2.39 mgd withdrawal was less than 0.05 feet on-site and off- site, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The upper Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at between 0.30 and 0.12 feet on-site, and between 0.30 and 0.01 feet off-site. The higher off-site figures are immediately proximate to the property. The lower Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at less than 0.05 feet at all locations, and at or less than 0.02 feet within six miles of the North Tract. 2.39 mgd - Cumulative Impact The cumulative impact to the surficial aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, was less than 0.05 feet on-site, and off-site to the north and east, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The cumulative impact to the upper Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 0.4 feet to 0.8 feet over all pertinent locations. The cumulative impact to the lower Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 1.0 to 1.9 feet over all pertinent locations. The conclusion drawn by Mr. Andreyev that the predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals is supported by the evidence and accepted. 1.54 mgd - Specific Impact The NCF model runs based on the more representative 1.54 mgd withdrawal predicted a surficial aquifer drawdown of less than 0.01 feet (i.e., no drawdown contour shown) on the North Tract, and a 0.01 to 0.02 foot drawdown at the location of the East Tract. The drawdown of the upper Floridan aquifer from the CUP modification was predicted at up to 0.07 feet on the property, and generally less than 0.05 feet off-site. There were no drawdown contours at the minimum 0.01 foot level that came within 9 miles of Silver Springs. The lower Floridan aquifer drawdown from the CUP modification was predicted at less than 0.01 feet (i.e., no drawdown contour shown) at all locations. 1.54 mgd - Cumulative Impact A comparison of the cumulative drawdown contours for the 2.36 mgd model and 1.54 mgd model show there to be a significant decrease in predicted drawdowns to the surficial and upper Floridan aquifers, with the decrease in the upper Floridan aquifer drawdown being relatively substantial, i.e., from 0.5 to 0.8 feet on-site predicted for the 2.36 mgd withdrawal, to 0.4 to 0.5 feet on-site for the 1.54 mgd model. Given the small predicted individual impact of the CUP on the upper Floridan aquifer, the evidence is persuasive that the cumulative impacts are the result of other end-of-permit user withdrawals. The drawdown contour for the lower Floridan aquifer predicted by the 1.54 mgd model is almost identical to that of the 2.36 mgd model, thus supporting the conclusion that predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals. Modeled Effect on Silver Springs As a result of the relocation of the extraction wells from the East Tract to the North Tract, the NCF model run at the 1.54 mgd withdrawal rate predicted springflow at Silver Springs to increase by 0.15 cfs. The net cumulative impact in spring flow as measured from 1995 conditions to the scenario in which all legal users, including Sleepy Creek, are pumping at full capacity at their end-of-permit rates for one year3/ is roughly 35.4 cfs, which is approximately 5 percent of Silver Springs’ current flow. However, as a result of the redistribution of the Sleepy Creek withdrawal, which is, in its current iteration, a legal and permitted use, the cumulative effect of the CUP modification at issue is an increase in flow of 0.l5 cfs. Dr. Kincaid agreed that there is more of an impact to Silver Springs when the pumping allowed by the CUP is located on the East Tract than there is on the North Tract, but that the degree of difference is very small. Dr. Knight testified that effect on the flow of Silver Springs from relocating the 1.46 mgd withdrawal from the East Tract to the North Tract would be “zero.” The predicted increase of 0.15 cfs is admittedly miniscule when compared to the current Silver Springs springflow of approximately 675 cfs. However, as small as the modeled increase may be -- perhaps smaller than its “level of certainty” -- it remains the best evidence that the impact of the CUP modification to the flow of Silver Springs will be insignificant at worst, and beneficial at best. Opposition to the NCF Model Petitioners submitted considerable evidence designed to call the results generated by the District’s and Sleepy Creek’s NCF modeling into question. Karst Features A primary criticism of the validity of the NCF model was its purported inability to account for the presence of karst features, including conduits, and their effect on the results. It was Dr. Kincaid’s opinion that the NCF model assigned transmissivity values that were too high, which he attributed to the presence of karst features that are collecting flow and delivering it to springs. He asserted that, instead of assuming the presence of karst features, the model was adjusted to raise the overall capacity of the porous medium to transmit water, and thereby match the observed flows. In his opinion, the transmissivity values of the equivalent porous media were raised so much that the model can no longer be used to predict drawdowns. That alleged deficiency in the model is insufficient for two reasons. First, as previously discussed in greater detail, the preponderance of the evidence in this case supports a finding that there are no karst features in the vicinity of the North Tract that would provide preferential pathways for water flow so as to skew the results of the NCF model. Second, Dr. Kincaid, while acknowledging that the NCF model is the best available tool for predicting impacts from groundwater extraction on the aquifer, suggested that a hybrid porous media and conduit model would be a better means of predicting impacts, the development of which would take two years or more. There is no basis for the establishment of a de facto moratorium on CUP permitting while waiting for the development of a different and, in this case, unnecessary model. For the reasons set forth herein, it is found that the NCF model is sufficient to accurately and adequately predict the effects of the Sleepy Creek groundwater withdrawals on the aquifers underlying the property, and to provide reasonable assurance that the standards for such withdrawals have been met. Recharge to the Aquifer Petitioners argued that the modeling results showing little significant drawdown were dependent on the application of unrealistic values for recharge or return flow from irrigation. In a groundwater model, as in the physical world, some portion of the water extracted from the aquifer is predicted to be returned to the aquifer as recharge. If more water is applied to the land surface than is being accounted for by evaporation, plant uptake and evapotranspiration, surface runoff, and other processes, that excess water may seep down into the aquifer as recharge. Recharge serves to replenish the aquifer and offset the effects of the groundwater withdrawal. Dr. Kincaid opined that the NCF modeling performed for the CUP application assigned too much water from recharge, offsetting the model's prediction of impacts to other features. It is reasonable to assume that there is some recharge associated with both agricultural and public supply uses. However, the evidence suggests that the impact of recharge on the overall NCF model results is insignificant on the predicted impacts to Silver Springs, the issue of primary concern. Mr. Hearn ran a simulation using the NCF model in which all variables were held constant, except for recharge. The difference between the “with recharge” and “without recharge" simulations at Silver Springs was 0.002 cfs. That difference is not significant, and is not suggestive of adverse impacts on Silver Springs from the CUP modification. Dr. Kincaid testified that “the recharge offset on the property is mostly impacting the surficial aquifer,” and that “the addition of recharge in this case didn't have much of an impact on the upper Floridan aquifer system.” As such, the effect of adding recharge to the model would be as to the effect of groundwater withdrawal on wetlands or surface water bodies, and not on springs. As previously detailed, the drawdown of the surficial aquifer simulated for the 2.39 mgd “no recharge” scenario were less than 0.05 feet on-site and off-site, except for a predicted 0.07 foot drawdown to the west of the North Tract. The predicted drawdown of the surficial aquifer for the 1.54 mgd “with recharge” scenario was 0.02 feet or less. The preponderance of the evidence supports a finding that drawdowns of either degree are less than that at which adverse impacts to wetlands or surface waters would occur. Thus, issues related to the recharge or return flows from irrigation are insufficient to support a finding or conclusion that the NCF model failed to provide reasonable assurance that the standards for issuance of the CUP modification were met. External Boundaries The boundaries of the NCF model are not isolated from the rest of the physical world. Rather, groundwater flows into the modeled area from multiple directions, and out of the modeled area in multiple directions. Inflows to the model area are comprised of recharge, which is an assigned value, and includes water infiltrating and recharging the aquifer from surface waters; injection wells; upward and downward leakage from lower aquifers; and flow across the external horizontal boundaries. Outflows from the model area include evapotranspiration; discharge to surface waters, including springs and rivers; extraction from wells; upward and downward leakage from lower aquifers; and flow against the external model boundaries. Dr. Kincaid testified that flow across the external model boundary is an unknown and unverifiable quantity which increases the uncertainty in the model. He asserted that in the calibrated version of the model, there is no way to check those flows against data. His conclusion was that the inability of the NCF model to accurately account for external boundary flow made the margin of error so great as to make the model an unreliable tool with which to assess whether the withdrawal approved by the proposed CUP modification will increase or decrease drawdown at Silver Springs. The District correlates the NCF model boundaries with a much larger model developed by the United States Geological Survey, the Peninsula of Florida Model, more commonly referred to as the Mega Model, which encompasses most of the State of Florida and part of Southeast Georgia. The Mega Model provides a means to acknowledge that there are stresses outside the NCF model, and to adjust boundary conditions to account for those stresses. The NCF is one of several models that are subsets of the Mega Model, with the grids of the two models being “nested” together. The 1995 base year of the NCF model is sufficiently similar to the 1993-1994 base year of the Mega Model as to allow for a comparison of simulated drawdowns calculated by each of the models. By running a Mega Model simulation of future water use, and applying the change in that use from 1993 base year conditions, the District was able to come to a representative prediction of specific boundary conditions for the 1995 NCF base year, which were then used as the baseline for simulations of subsequent conditions. In its review of the CUP modification, the District conducted a model validation simulation to measure the accuracy of the NCF model against observed conditions, with the conditions of interest being the water flow at Silver Springs. The District ran a simulation using the best information available as to water use in the year 2010, the calculated boundary conditions, irrigation, pumping, recharge, climatic conditions, and generally “everything that we think constitutes that year.” The discharge of water at Silver Springs in 2010 was measured at 580 cfs. The discharge simulated by the NCF model was 545 cfs. Thus, the discharge predicted by the NCF model simulation was within six percent of the observed discharge. Such a result is generally considered in the modeling community to be “a home run.” Petitioners’ objections to the calculation of boundary conditions for the NCF model are insufficient to support a finding that the NCF model is not an appropriate and accurate tool for determining that reasonable assurance has been provided that the standards for issuance of the CUP modification were met. Cumulative Impact Error As part of the District’s efforts to continually refine the NCF, and in conjunction with a draft minimum flows and levels report for Silver Springs and the Silver River, the cumulative NCF model results for the period of baseline to 2010 were compared with the simulated results from the Northern District Model (NDF), a larger model that overlapped the NCF. As a result of the comparison, which yielded different results, it was discovered that the modeler had “turned off” not only the withdrawal pumps, but inputs to the aquifer from drainage wells and sinkholes as well. When those inputs were put back into the model run, and effects calculated only from withdrawals between the “pumps-off” condition and 2010 pumping conditions, the cumulative effect of the withdrawals was adjusted from a reduction in the flow at Silver Springs of 29 cfs to a reduction of between 45 and 50 cfs, an effect described as “counterintuitive.” Although that result has not undergone peer review, and remains subject to further review and comparison with the Mega Model, it was accepted by the District representative, Mr. Bartol. Petitioners seized upon the results of the comparison model run as evidence of the inaccuracy and unreliability of the NCF model. However, the error in the NCF model run was not the result of deficiencies in the model, but was a data input error. Despite the error in the estimate of the cumulative effect of all users at 2010 levels, the evidence in this case does not support a finding that the more recent estimates of specific impact from the CUP at issue were in error. NCF Model Conclusion As has been discussed herein, a model is generally the best means by which to calculate conditions and effects that cannot be directly observed. The NCF model is recognized as being the best tool available for determining the subsurface conditions of the model domain, having been calibrated over a period of years and subject to peer review. It should be recognized that the simulations run using the NCF model represent the worst—case scenario, with all permittees simultaneously drawing at their full end-of-permit allocations. There is merit to the description of that occurrence as being “very remote.” Thus, the results of the modeling represent a conservative estimate of potential drawdown and impacts. While the NCF model is subject to uncertainty, as is any method of predicting the effects of conditions that cannot be seen, the model provides reasonable assurance that the conditions simulated are representative of the conditions that will occur as a result of the withdrawals authorized by the CUP modification. Environmental Resource Permit The irrigation proposed by the CUP will result in runoff from the North Tract irrigated pastures in excess of that expected from the improved pastures, due in large measure to the diminished storage capacity of the soil. Irrigation water will be applied when the soils are dry, and capable of absorbing water not subject to evaporation or plant uptake. The irrigation water will fill the storage space that would exist without irrigation. With irrigation water taking up the capacity of the soil to hold water, soils beneath the irrigation pivots will be less capable of retaining additional moisture during storm events. Thus, there is an increased likelihood of runoff from the irrigated pastures over that expected with dry soils. The increase in runoff is expected to be relatively small, since there should be little or no irrigation needed during the normal summer wet season. The additional runoff may have increased nutrient levels due to the increased cattle density made possible by the irrigation of the pastures. The CUP has a no—impact requirement for water quality resulting from the irrigation of the improved pasture. Thus, nutrients leaving the irrigated pastures may not exceed those calculated to be leaving the existing pre-development use as improved pastures. Retention Berms The additional runoff and nutrient load is proposed to be addressed by constructing a system of retention berms, approximately 50,0004/ feet in length, which is intended to intercept, retain, and provide treatment for runoff from the irrigated pasture. The goal of the system is to ensure that post—development nutrient loading from the proposed irrigated pastures will not exceed the pre—development nutrient loading from the existing improved pastures. An ERP permit is required for the construction of the berm system, since the area needed for the construction of the berms is greater than the one acre in size, and since the berms have the capability of impounding more than 40 acre-feet of water. The berms are to be constructed by excavating the top nine inches of sandy, permeable topsoil and using that permeable soil to create the berms, which will be 1 to 2 feet in height. The water storage areas created by the excavation will have flat or horizontal bottoms, and will be very shallow with the capacity to retain approximately a foot of water. The berms will be planted with pasture grasses after construction to provide vegetative cover. The retention berm system is proposed to be built in segments, with the segment designed to capture runoff from a particular center pivot pasture to be constructed prior to the commencement of irrigation from that center pivot. A continuous clay layer underlies the areas in which the berms are to be constructed. The clay layer varies from 18 to 36 inches below the ground surface, with at least one location being as much as five feet below the ground surface. As such, after nine inches of soil is scraped away to create the water retention area and construct the berm, there will remain a layer of permeable sandy material above the clay. The berms are to be constructed at least 25 feet landward of any jurisdictional wetland, creating a “safe upland line.” Thus, the construction, operation, and maintenance of the retention berms and redistribution swales will result in no direct impacts to jurisdictional wetlands or other surface waters. There will be no agricultural activities, e.g., tilling, planting, or mowing, within the 25-foot buffers, and the buffers will be allowed to establish with native vegetation to provide additional protection for downgradient wetlands. As stormwater runoff flows from the irrigated pastures, it may, in places, create concentrated flow ways. Redistribution swales will be built in those areas to spread any remaining overland flow of water and reestablish sheet flow to the retention berm system. At any point at which water may overtop a berm, the berm will be hardened with rip—rap to insure its integrity. The berms are designed to intercept and collect overland flow from the pastures and temporarily store it behind the berms, regaining the soil storage volume lost through irrigation. A portion of the runoff intercepted by the berm system will evaporate. The majority will infiltrate either through the berm, or vertically into the subsurface soils beneath it. When the surficial soils become saturated, further vertical movement will be stopped by the impermeable clay layer underlying the site. The runoff water will then move horizontally until it reemerges into downstream wetland systems. Thus, the berm system is not expected to have a measurable impact on the hydroperiod of the wetlands on the North Tract. Phosphorus Removal Phosphorus tends to get “tied up” in soil as it moves through it. Phosphorus reduction occurs easily in permeable soil systems because it is removed from the water through a chemical absorption process that is not dependent on the environment of the soil. As the soils in the retention areas and berms go through drying cycles, the absorption capacity is regenerated. Thus, the retention system will effectively account for any increase in phosphorus resulting from the increased cattle density allowed by the irrigation such that there is expected to be no increase in phosphorus levels beyond the berm. Nitrogen Removal When manure is deposited on the ground, primarily as high pH urine, the urea is quickly converted to ammonia, which experiences a loss of 40 to 50 percent of the nitrogen to volatization. Soil conditions during dry weather conditions are generally aerobic. Remaining ammonia in the manure is converted by aerobic bacteria in the soil to nitrates and nitrites. Converted nitrates and nitrites from manure, along with nitrogen from fertilizer, is readily available for uptake as food by plants, including grasses and forage crops. Nitrates and nitrites are mobile in water. Therefore, during rain events of sufficient intensity to create runoff, the nitrogen can be transported downstream towards wetlands and other receiving waters, or percolate downward through the soil until blocked by an impervious barrier. During storm events, the soils above the clay confining layer and the lower parts of the pervious berms become saturated. Those saturated soils are drained of oxygen and become anaerobic. When nitrates and nitrites encounter saturated conditions, they provide food for anaerobic bacteria that exist in those conditions. The bacteria convert nitrates and nitrites to elemental nitrogen, which has no adverse impact on surface waters or groundwater. That process, known as denitrification, is enhanced in the presence of organic material. The soils from which the berms are constructed have a considerable organic component. In addition to the denitrification that occurs in the saturated conditions in and underlying the berms, remaining nitrogen compounds that reemerge into the downstream wetlands are likely to encounter organic wetland-type soil conditions. Organic wetland soils are anaerobic in nature, and will result in further, almost immediate denitrification of the nitrates and nitrites in the emerging water. Calculation of Volume - BMPTRAINS Model The calculation of the volume necessary to capture and store excess runoff from the irrigated pastures was performed by Dr. Wanielista using the BMPTRAINS model. BMPTRAINS is a simple, easy to use spreadsheet model. Its ease of use does not suggest that it is less than reliable. The model has been used as a method of calculating storage volumes in many conditions over a period of more than 40 years. The model was used to calculate the storage volumes necessary to provide storage and treatment of runoff from fifteen “basins” that had a control or a Best Management Practice associated with them. All of the basins were calculated as being underlain by soils in poorly-drained hydrologic soil Group D, except for the basin in the vicinity of Pivot 6, which is underlain by the more well-drained soil Group A. The model assumed about percent of the property to have soil Group A soils, an assumption that is supported by the evidence. Soil moisture conditions on the property were calculated by application of data regarding rainfall events and times, the irrigation schedule, and the amount of irrigation water projected for use over a year. The soil moisture condition was used to determine the amount of water that could be stored in the on-site soils, known as the storage coefficient. Once the storage coefficient was determined, that data was used to calculate the amount of water that would be expected to run off of the North Tract, known as the curve number. The curve number is adjusted by the extent to which the storage within a soil column is filled by the application of irrigation water, making it unable to store additional rainfall. As soil storage goes down, the curve number goes up. Thus, a curve number that approaches 100 means that more water is predicted to run off. Conversely, a lower curve number means that less water is predicted to run off. The pre-development curve number for the North Tract was based on the property being an unirrigated, poor grass area. A post-development curve number was assigned to the property that reflected a wet condition representative of the irrigated soils beneath the pivots. In calculating the storage volume necessary to handle runoff from the basins, the wet condition curve number was adjusted based on the fact that there is a mixture of irrigated and unirrigated general pasture within each basin to be served by a segment of the retention berm system, and by the estimated 15 percent of the time that the irrigation areas would be in a drier condition. In addition, the number was adjusted to reflect the 8 to 10 inches of additional evapotranspiration that occurs as a result of irrigation. The BMPTRAINS model was based on average annual nutrient-loading conditions, with water quality data collected at a suitable point within Reach 22, the receiving waterbody. The effects of nutrients from the irrigated pastures on receiving waterbodies is, in terms of the model, best represented by average annual conditions, rather than a single highest-observed nutrient value. Pre-development loading figures were based on the existing use of the property as unirrigated general pasture. The pre-development phosphorus loading figure was calculated at an average event mean concentration (EMC) of 0.421 milligrams per liter (mg/l). The post—condition phosphorus loading figure was calculated at an EMC of 0.621 mg/l. Therefore, in order to achieve pre-development levels of phosphorus, treatment to achieve a reduction in phosphorus of approximately 36 percent was determined to be necessary. The pre-development nitrogen loading figure was calculated at an EMC of 2.6 mg/l. The post—condition nitrogen loading figure was calculated at an EMC of 3.3 mg/l. Therefore, in order to achieve pre-development levels of nitrogen, treatment to achieve a reduction in nitrogen of approximately 25 percent was determined to be necessary. The limiting value for the design of the retention berms is phosphorus. To achieve post-development concentrations that are equal to or less than pre-development concentrations, the treatment volume of the berm system must be sufficient to allow for the removal of 36 percent of the nutrients in water being retained and treated behind the berms, which represents the necessary percentage of phosphorus. In order to achieve the 36 percent reduction required for phosphorus, the retention berm system must be capable of retaining approximately 38 acre—feet of water from the 15 basins. In order to achieve that retention volume, a berm length of approximately 50,000 linear feet was determined to be necessary, with an average depth of retention behind the berms of one foot. The proposed length of the berms is sufficient to retain the requisite volume of water to achieve a reduction in phosphorus of 36 percent. Thus, the post-development/irrigation levels of phosphorus from runoff are expected to be no greater than pre-development/general pasture levels of phosphorus from runoff. By basing the berm length and volume on that necessary for the treatment of phosphorus, there will be storage volume that is greater than required for a 25 percent reduction in nitrogen. Thus, the post-development/irrigation levels of nitrogen from runoff are expected to be less than pre- development/general pasture levels of nitrogen from runoff. Mr. Drummond admitted that the design of the retention berms “shows there is some reduction, potentially, but it's not going to totally clean up the nutrients.” Such a total clean-up is not required. Rather, it is sufficient that there is nutrient removal to pre-development levels, so that there is no additional pollutant loading from the permitted activities. Reasonable assurance that such additional loading is not expected to occur was provided. Despite Mr. Drummond’s criticism of the BMPTRAINS model, he did not quantify nutrient loading on the North Tract, and was unable to determine whether post-development concentrations of nutrients would increase over pre-development levels. As such, there was insufficient evidence to counter the results of the BMPTRAINS modeling. Watershed Assessment Model In order to further assess potential water quantity and water quality impacts to surface water bodies, and to confirm stormwater retention area and volume necessary to meet pre-development conditions, Sleepy Creek utilized the Watershed Assessment Model (WAM). The WAM is a peer-reviewed model that is widely accepted by national, state, and local regulatory entities. The WAM was designed to simulate water balance and nutrient impacts of varying land uses. It was used in this case to simulate and provide a quantitative measure of the anticipated impacts of irrigation on receiving water bodies, including Mill Creek, Daisy Creek, the Ocklawaha River, and Silver Springs. Inputs to the model include land conditions, soil conditions, rain and climate conditions, and water conveyance systems found on the property. In order to calculate the extent to which nutrients applied to the land surface might affect receiving waters, a time series of surface water and groundwater flow is “routed” through the modeled watershed and to the various outlets from the system, all of which have assimilation algorithms that represent the types of nutrient uptakes expected to occur as water goes through the system. Simulations were performed on the North Tract in its condition prior to acquisition by Sleepy Creek, in its current “exempted improved pasture condition,” and in its proposed “post—development” pivot-irrigation condition. The simulations assessed impacts of the site conditions on surface waters at the point at which they leave the property and discharge to Mill Creek, and at the point where Mill Creek merges into the Ocklawaha River. The baseline condition for measuring changes in nutrient concentrations was determined to be that lawfully existing at the time the application was made. Had there been any suggestion of illegality or impropriety in Sleepy Creek’s actions in clearing the timber and creating improved pasture, a different baseline might be warranted. However, no such illegality or impropriety was shown, and the SJRWMD rules create no procedure for “looking back” to previous land uses and conditions that were legally changed. Thus, the “exempted improved pasture condition” nutrient levels are appropriate for comparison with irrigated pasture nutrient levels. The WAM simulations indicated that nitrogen resulting from the irrigation of the North Tract pastures would be reduced at the outflow to Mill Creek at the Reach 22 stream segment from improved pasture levels by 1.7 percent in pounds per year, and by 0.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 1.3 percent in pounds per year, and 0.5 percent in milligrams per liter of water. These levels are small, but nonetheless support a finding that the berm system is effective in reducing nitrogen from the North Tract. Furthermore, the WAM simulations showed levels of nitrogen from the irrigated pasture after the construction of the retention berms to be reduced from that present in the pre- development condition, a conclusion consistent with that derived from the BMPTRAINS model. The WAM simulations indicated that phosphorus from the irrigated North Tract pastures, measured at the outflow to Mill Creek at the Reach 22 stream segment, would be reduced from improved pasture levels by 3.7 percent in pounds per year, and by 2.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 2.5 percent in pounds per year, and 1.6 percent in milligrams per liter of water. Those levels are, again, small, but supportive of a finding of no impact from the permitted activities. The WAM simulations showed phosphorus in the Ocklawaha River at the Eureka Station after the construction of the retention berms to be slightly greater than those simulated for the pre-development condition (0.00008 mg/l) -- the only calculated increase. That level is beyond miniscule, with impacts properly characterized as “non- measurable” and “non-detectable.” In any event, total phosphorus remains well below Florida’s nutrient standards. The WAM simulations were conducted based on all of the 15 pivots operating simultaneously at full capacity. That amount is greater than what is allowed under the permit. Thus, according to Dr. Bottcher, the predicted loads are higher than those that would be generated by the permitted allocation, making his estimates “very conservative.” Dr. Bottcher’s testimony is credited. During the course of the final hearing, the accuracy of the model results was questioned based on inaccuracies in rainfall inputs due to the five-mile distance of the property from the nearest rain station. Dr. Bottcher admitted that given the dynamics of summer convection storms, confidence that the rain station rainfall measurements represent specific conditions on the North Tract is limited. However, it remains the best data available. Furthermore, Dr. Bottcher testified that even if specific data points simulated by the model differ from that recorded at the rain station, that same error carries through each of the various scenarios. Thus, for the comparative purpose of the model, the errors get “washed out.” Other testimony regarding purported inaccuracies in the WAM simulations and report were explained as being the result of errors in the parameters used to run alternative simulations or analyze Sleepy Creek’s simulations, including use of soil types that are not representative of the North Tract, and a misunderstanding of dry weight/wet weight loading rates. There was agreement among witnesses that the WAM is regarded, among individuals with expertise in modeling, as an effective tool, and was the appropriate model for use in the ERP application that is the subject of this proceeding. As a result, the undersigned accepts the WAM simulations as being representative of comparative nutrient impacts on receiving surface water bodies resulting from irrigation of the North Tract. The WAM confirmed that the proposed retention berm system will be sufficient to treat additional nutrients that may result from irrigation of the pastures, and supports a finding of reasonable assurance that water quality criteria will be met. With regard to the East Tract, the WAM simulations showed that there would be reductions in nitrogen and phosphorus loading to Daisy Creek from the conversion of the property to irrigated pasture. Those simulations were also conservative because they assumed the maximum number of cattle allowed by the nutrient balance, and did not assume the 30 percent reduction in the number of cattle under the NMP so as to allow existing elevated levels of phosphorus in the soil from the sod farm to be “mined” by vegetation. Pivot 6 The evidence in this case suggests that, unlike the majority of the North Tract, a small area on the western side of the North Tract drains to the west and north. Irrigation Pivot is within that area. Dr. Harper noted that there are some soils in hydrologic soil Group A in the vicinity of Pivot 6 that reflect soils with a deeper water table where rainfall would be expected to infiltrate into the ground. Dr. Kincaid’s particle track analysis suggested that recharge to the surficial aquifer ultimately discharges to Mill Creek, except for recharge at Pivot 11, which is accounted for by evapotranspiration, and recharge at Pivot 6. Dr. Kincaid concluded that approximately 1 percent of the recharge to the surficial aquifer beneath the North Tract found its way into the upper Floridan aquifer. Those particle tracks originated only on the far western side of the property, and implicated only Pivot 6, which is indicative of the flow divide in the Floridan aquifer. Of the 1 percent of particle tracks entering the Floridan aquifer, some ultimately discharged at the St. John’s River, the Ocklawaha River, or Mill Creek. Dr. Kincaid opined, however, that most ultimately found their way to Silver Springs. Given the previous finding that the Floridan aquifer beneath the property is within the Silver Springs springshed for less than a majority of the time, it is found that a correspondingly small fraction of the less than 1 percent of the particle tracks originating on the North Tract, perhaps a few tenths of one percent, can reach Silver Springs. Dr. Bottcher generally agreed that some small percentage of the water from the North Tract may make it to the upper Floridan aquifer, but that amount will be very small. Furthermore, that water reaching the upper Floridan aquifer would have been subject to the protection and treatment afforded by the NMP and the ERP berms. The evidence regarding the somewhat less restrictive confinement of the aquifer around Pivot 6 is not sufficient to rebut the prima facie case that the CUP modification, coupled with the ERP, will meet the District’s permitting standards. Public Interest The primary basis upon which Sleepy Creek relies to demonstrate that the CUP is “consistent with the public interest” is that Florida's economy is highly dependent upon agricultural operations in terms of jobs and economic development, and that there is a necessity of food production. Sleepy Creek could raise cattle on the property using the agriculturally-exempt improved pastures, but the economic return on the investment would be questionable without the increased quality, quantity, and reliability of grass and forage crop production resulting from the proposed irrigation. Sleepy Creek will continue to engage in agricultural activities on its properties if the CUP modification is denied. Although a typical Florida beef operation could be maintained on the property, the investment was based upon having the revenue generation allowed by grass-fed beef production in order to realize a return on its capital investment and to optimize the economic return. If the CUP modification is denied, the existing CUP will continue to allow the extraction of 1.46 mgd for use on the East Tract. The preponderance of the evidence suggests that such a use would have greater impacts on the water levels at Silver Springs, and that the continued use of the East Tract as a less stringently-controlled sod farm would have a greater likelihood of higher nutrient levels, particularly phosphorus levels which are already elevated.

GARY EARLY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 29th day of April, 2015.
The Issue The issue for consideration herein is whether Sarasota County Utilities should be issued a consumptive use permit to draw water from the 14 wells in issue here located in Sarasota County.
Findings Of Fact At all times pertinent to the issues herein, the Respondent, District, was the state agency responsible for themanagement of water resources within its area of geographical jurisdiction. Included therein was the responsibility for the permitting of consumptive water use. The Respondent, Sarasota County, is a political subdivision of the State of Florida and operates a public utilities division which is charged with meeting, among other things, the potable water needs of the residents of the County. Petitioners Wyatt S. Bishop and Joan Jones are both residents of Sarasota County and both draw their potable water from wells which utilize the aquifers pertinent to the wells for which the permit in issue here relate. Mr. Bishop lives approximately 7.5 miles north of the Carlton Reserve, the property on which the wells in issue are located, and Ms. Jones lives approximately 7 miles from the Reserve, but in a different direction. Sarasota County filed an application for a consumptive use permit with the District on January 28, 1987 requesting an average daily withdrawal of 10.71 million gallons per day, (mgd), and a peak monthly withdrawal of 15.55 mgd. This application, assigned number 208836.00, was, over the next three years, amended by the County four separate times. These amendments reflected revised water demand determinations and were submitted to provide additional information requested by the District. The District issued a preliminary staff report and proposed intent on March 26, 1991 reflecting an approved withdrawal in the amount of 7.28 mgd average daily withdrawal and 11.1 mgd peak monthly withdrawal. These figures were revised, however, byan amendment by the District on July 8, 1991, and as amended, authorize 7.303 mgd average daily withdrawal and 9.625 mgd peak monthly withdrawal. The County's application was reviewed by an experienced hydrologist in the District office with extensive permit review experience who utilized, in his evaluation of the permit, the pertinent District rules and policies. By way of background, to more easily understand the circumstances here, Sarasota entered into a contract with Manatee County in 1973 which called for the latter to provide up to 10 mgd of water for a period of 40 years, up to and including the year 2013. However, in 1979, Manatee County's utilities director advised Sarasota County that it, Sarasota County, could not continue to rely on Manatee County's water after the expiration of the current contract, and would, therefore, have to become self sufficient in water. Since the MacArthur tract, now known as the Carlton Reserve, had just recently been identified by, inter alia, the United States Geological Service as a potential long term water source for Sarasota County, after Manatee County advised Sarasota County of its future expectations, Sarasota County and the Manasota Basin Board hired a consulting firm to conduct hydrological testing on the Carlton Reserve. This study concluded that the Reserve had sufficient water resources to satisfy the needs of the unincorporated areas of Sarasota County for an extended time into the future. In 1985, because of its increased water needs and thetime necessary to complete required studies on the utilization of the Myakka River, a surface water resource, Sarasota County concluded that it was suffering a water supply shortage and entered into a supplemental contract with Manatee County to provide 2 million gallons of water per day over a 5 year period which would expire in 1990. Sarasota County had not, however, been idle with regard to the investigation of other water resources. Studies done included not only the Myakka River mentioned above but a reservoir owned by the City of Bradenton, and the Peace River. Nonetheless, it was determined that the Carlton Reserve was the best source available overall, and in 1987, the County filed the application in issue here. The permit was under consideration for approximately 3 1/2 years before the initial decision by the District to grant it. During that time the County experienced a significant deficiency in its water sources and found it necessary, on February 5, 1991, to enter into another contract with Manatee County to supply an addition 5 mgd. Terms of that contract clearly indicate the expectations of both parties that Sarasota County will take reasonable steps to develop its own water resources. It is not as though Sarasota County sat quietly in the interim, however, and allowed the situation to develop. A building moratorium to halt additional construction was proposed and as a result, economic forces in the County indicated a potential loss of jobs to County residents. None of this would be desirable from an economicstandpoint. In the course of the permit application process, 12 test wells were sunk to conduct aquifer pump tests; to assess water quality, amounts and availability, aquifer characteristics and drawdown; and to determine the impact of withdrawal on water quality. Eight of these 12 wells are located on the Carlton Reserve. The other 4 are located on property owned by the MacArthur Foundation which is contiguous to the Carlton Reserve property and from which Sarasota has a right by easement to draw water. The 2 wells yet to be constructed will be on Sarasota County property. Sarasota County currently receives 10 mgd of water under its contract with Manatee County; an additional 5 mgd under the February 5, 1991 contract; 2 mgd from the University wellfield, (with a peak withdrawal rate of 3 mgd); and .9 mgd from the Sorrento wellfield, (with a peak withdrawal rate of 1.1 mgd). This latter source is only producing currently .6 mgd of potable water due to constraints imposed by the water treatment requirements. Taken together, the current Sarasota County supply constitutes 18.6 mgd. The above does not take into account the County's agreement with the City of Sarasota calling for the purchase of up to 2 mgd. Since this source is not reliable, it is not included in the total, and the City is not considered an available water source. In addition, the District and Sarasota County stipulated on July 15, 1991 that within 30 days, the County would apply tophase out routine water production from the Sorrento wellfield, relying on it only in emergency situations with District consent. For this reason, it, too, is not considered an available water supply source. These currently existing sources, with modifications as described, will be the primary sources of potable water provided to 6 major service areas in Sarasota County when the County's water treatment plant and transmission system are complete in 1993. In attempting to define the County's future water requirements, two major criteria were considered. The first was the County's historical water demand, and the second, modifying it, relates to the demand arising as a result of new water users being added to the system as a result of the County's capital improvements and acquisition program. Water resources are not unlimited. Current resources come primarily from Manatee County and there are constraints on this supply as it is made available to Sarasota County. For example, the 10 mgd contract expires in 2013. The 5 mgd contract expires in 2001. Though the latter is subject to renewal, renewal is contingent upon the availability of water supply at that time, and that is not a sure thing. It can, therefore, readily be seen that 15 out of the 18.6 mgd routinely available now comes from Manatee County, and those sources are not perpetual. In addition, it is conceivable that Manatee County may pre-blend the water it delivers to Sarasota County with water of lesser quality, so that the delivered water may exceed the total dissolved solids standard of 500 ppm for potable water. If thewater from Manatee County were reduced to that quality, the University wellfield supply, which currently exceeds standards itself, and which relies on blending with better quality Manatee County water to be potable, would also be removed as a source of potable water to Sarasota County. In order to comply with the provisions of Section 373.171, Florida Statutes, which requires the District to regulate the use of water by apportionment, limitation, or rotating uses, to obtain the most beneficial use of water resources and to protect the public health, safety and welfare, the District analyzed the available water sources and determined that Sarasota County relies upon its 10 mgd supply from Manatee County and the 2 mgd supply from University wellfield to constitute 12 mgd usable water. The 5 mgd from Manatee County would be used only in an emergency situation, and the Sorrento wellfield would be abandoned. Future water demands must be predicted relying in great part upon an historic record of prior water use. Utilizing a statistical procedure called linear regression, a methodology accepted by the District, indicated a water demand figure for the period from 1992 to 1997 based upon six use points extending from 1985 to 1990. These use records reflected a low of 9.733 mgd and a high of 12.808 mgd, the former being in 1985 and the latter in 1990. In addition, the County estimated that its capital improvement program would add between 10 and 12 thousand customers who presently use private wells, whose water use would constitute approximately 2 mgd of additional demand. The County's program toacquire some 42 private franchises now serving customers would add an additional demand of 2 mgd. Taken together, these programs would add in approximately 1.8 mgd per year to the need assessment, and it would therefore appear that by 1997, the County's average daily demand, considering all new users, would be 17.84 mgd. The water to be drawn from the Carlton Reserve is not currently potable and will require some form of treatment to render it so. Sarasota County proposes to use the Electrodialysis Reversal process, (EDR), because, in the County's judgement, it is more efficient than others such as reverse osmosis and ion exchange. Whereas EDR is rated at up to 85% efficient, the others range between 50% to 75% efficient. In that regard, in order to determine the maximum amount of water to be drawn, providing a safety factor for a treatment plant operation that is not working up to peak capacity in computing the water needs, the EDR process was determined to be no more than 80% efficient. Factoring in that efficiency potential, when the 1997 average daily demand is subtracted from the County's projected water capacity, the withdrawal need in 1997 is determined to be 7.303 mgd. However, as a part of its permitting process, the County also calculated its peak month daily demand. This is a figure which represents the maximum amount permitted to be drawn on a daily basis during the peak demand period. This peak period was determined under Section b 3.2 of the District's Basis of Review by taking the 1989 daily flow and using a sliding 31 day calendar to determine the highest historical 31 day flow. Thisresulted in a peak month coefficient of 6.16 which was then multiplied by the 1997 average daily demand of 17.842 mgd which resulted in a peak month daily demand of 20.7 mgd. When existing water supplies are removed and the 80% EDR treatment process factor is applied, the amount of raw water needed from the wellfield in issue on a peak monthly basis would be 9.625 mgd. This peak monthly basis figure is considered because of the intermittent periods of low rainfall and high water demand within the County. Accepting the 1.8 gpd yearly increase; the peak factor of 1.16; and the assumed water supply capacity of 18.6 mgd; Sarasota County's need will exceed its available supplies by 1993. In fact, the County is already experiencing low water pressure in part of its service area during peak demand periods. County experts estimate that without the requested water from the Carlton Tract, Sarasota County can expect to experience dry periods as early as 1993 during the periods of peak water usage, generally between April and June. For the above reason, when the application and its supporting information was reviewed by Mr. Basso, the District hydrologist with extensive experience reviewing more than 300 water use application, he determined that the water supplies requested are necessary to meet the County's certain reasonable demand, and that this meets the criteria set out in Rule 40D - 2.301(1)(a), F.A.C. Turning to the issue of hydrologic and environmental impacts, the District's Basis For Review of Water Permit Applications provides for the use of a "water use model" inevaluating water needs and the appropriateness of a proposed withdrawal. In preparing its submittal to the District, Sarasota County performed certain tests and modeling to derive the statistical and scientific information used in support of its application. Specifically it used the USGS' MODFLOW model utilizing information obtained from the pump tests run on the wells in the pertinent areas. Consistent with the District's rule, the water data and aquifer drawdown were determined by simulated pumping. The tests run also provided the information on water quality in the aquifer and physical characteristics including transmissivity, storage coefficient, specific yield and leakance between aquifers. This data also helped in defining the hydrogeologic framework of the Carlton Reserve. The Carlton Reserve's hydrogeology listed in descending order from the surface, includes a surficial aquifer which varies in depth between 19 and 70 feet across the Reserve; a semi-confining clay unit separating it from the intermediate aquifer; the upper intermediate and lower intermediate aquifer which range in depth from 140 to 180 feet across the Reserve; another confining layer, and the Upper and Lower Floridan aquifers. The hydrology and groundwater modeling expert who constructed the model used in Sarasota County's permit application concluded that the water table drawdown at the Reserve property boundary in the surficial aquifer would be less than .3 of a foot; less than .4 of a foot in the intermediate aquifer; and 2.9 feet in the Upper Florida aquifer. The water to be drawn consistentwith this instant permit, if approved, would come from the Upper Floridan aquifer on the Reserve. The County's experts were conservative in the assumptions used in the groundwater model. It was assumed there would be no lateral water flow into the model area and no recharge. In addition, the model called for all pumps to run simultaneously at a maximum drawdown of 12.65 mgd for 90 days rather than at the requested quantity of 9.625 mgd. Utilization of these assumptions provided a scenario wherein "severe" impacts would be encountered. Based on the testing and the modeling done, expert opinion was that there would be no quantity or quality changes that would adversely effect water resources including ground and surface water. This meets the criteria of Rule 40D-2.301. This opinion was concurred in the District's hydrology expert. Nonetheless, in its proposed approval, the District has imposed special permitting conditions which require the County to monitor, analyze, and report water quality and water table level information to the District on a monthly and annual basis. When it evaluates the information supplied by an applicant relating to ground water monitoring, the District is required to consider certain presumptions set forth in its Basis For Review. For example, the District presumes that if there is a drawdown of more than 1 foot in the surficial aquifer at a wetland, adverse environmental impacts will occur. In the instant case, the County model concluded that the actual drawdown in the surficial aquifer at the Carlton Reserve is less than .6 of onefoot and, therefore, there should be no adverse environmental impact resulting from the withdrawal. Nonetheless, the County has developed several plans designed to provide information on environmental impacts which will continuously monitor such parameters as rainfall and evaporation, wetlands hydroperiod changes and vegetative changes in the wetlands to detect any changes which might be attributed to the water pumping. These plans have been made special conditions to the water use permit, and in the opinion of the County's ecology and hydrology expert, would enable the County to adequately monitor and detect any pertinent changes to the pertinent factors concerned on the Carlton Reserve. If wetland changes are detected, a contingency plan will be in effect which will require an alteration of pumping schedules or other action to minimize any adverse impacts. The District expert in wetlands and wildlife habitat has opined that these measures, with which he is familiar, are adequate to insure that adverse impacts to the wetlands will not occur. This is consistent with the provisions of Rule 40D-2.301(1). As was stated previously, the water to be drawn pursuant to this permit will be drawn from the Upper Floridan aquifer. This water is not potable but is treatable and is the lowest quality water which can be economically used by the County. Water of a lower quality does exist in the Lower Florida aquifer, but it is not economically treatable, and, in addition, use of this Lower Floridan aquifer might cause vertical movement of the poorer quality water into the upper strata. For all practical purposes,then, the lowest quality water available to it will be used by the County and this is consistent with the District's basis for review. Expert testimony indicates that saline water will not be infused into the Upper Floridan aquifer. Salt water intrusion generally occurs when groundwater is brought to a level below sea level. Even at the point of maximum actual drawdown as a result of pumping on the Reserve, the fresh water level will remain at least 20 feet above sea level, and as a result of the difference in water level, no saline water intrusion into the fresh water supply will occur even though salt water intrusion can also occur as a result of upward vertical movement of lower quality water due to withdrawal. The District's hydrologist and reviewing official also concluded that because of the confining layer below the aquifer from which water will be withdrawn, there would not be any significant upward movement of lesser quality water. The District's basis of review also envisions an aquifer pollution if a proposed withdrawal would spread an identified contamination plume. Here no contamination has been identified in the area from which the water will be drawn, and therefore, contamination would not be spread. The Basis for Review also infers there will be adverse impact to off site land if there is a significant drawdown of surface water bodies or if damage to crops or other vegetation can be expected. Here, the water table drawdown at the boundary of the Carlton Reserve is anticipated at less than .3 of one foot and any drawdown further out from the Reserve can be expected tobe even less. As a result, no adverse impact to existing off site land useage is expected. With regard to Rule 40D-2.301(1)(i), relating to an adverse impact on existing legal uses, the District presumes that no adverse impact will exist if the drawdown in the water table is no more than 2 feet at an affected well, or the potentiometric surface at the well is not lowered by more than 5 feet. Here, again applying the County's groundwater modeling demonstrates that the drawdown at its worst, in the Upper Floridan aquifer, would be no more than 2.9 feet at the Reserve boundary and much less at the Petitioners' wells. Both Mr Bishop's and Ms. Jones' wells are approximately 7.5 and 7 miles, respectively, from the closest well on the Reserve property. Ms. Jones' well is drilled into the intermediate aquifer which is above that which the County proposes to use and should not be impacted. Mr. Bishop draws water from the intermediate and surficial aquifers, both of which are above the Upper Florida aquifer identified for use here, and the groundwater modeling would suggest that his well would not be impacted either. Sarasota County's application contains reference to numerous proposals for water conservation measures which it intends to implement or has already implemented. It has adopted ordinances to enforce the District's watering restrictions and is currently implementing a block inverted use rate structure to promote conservation. It has developed programs for use in the schools outlining water conservation efforts and is developing programs topromote the increased use of treated waste water for golf course irrigation. The requirement for a water conservation plan such as is described and envisioned by the County is a condition of the water use permit proposed, and in addition, the County has adopted an Ordinance, (90-38) which modifies its building code to require installation of water conservation devices in new buildings erected in the County. It has developed proposals for conservation measures such as water auditing, meter testing, leak detection, system looping, and pressure reduction, and has selected the EDR process of water purification as the most efficient use of groundwater resources. Petitioner, Bishop, testified to his belief that approval of this permit and the resultant water withdrawal on the Carlton Reserve would necessitate an expansion of the boundaries of the District's Eastern Tampa Bay Water Use Caution Area to a point where his property would be encompassed therein. In support of his position, Mr. Bishop offered a notice to the effect that new ground water withdrawals would not be permitted within a certain "most impacted area" within the caution area. There was, however, no independent evidence from hydrologists, geologists, or other conservationists, or individuals familiar with the water conservation process, to support Mr. Bishop's contention that either the boundaries would be expanded or that withdrawal of the proposed permitted amounts of water from the Carlton Reserve would cause the boundaries to be expanded. By the same token, Mr. Bishop's contention that theproposed withdrawal from the wells here in issue would adversely effect his ability to draw water from his existing well was not supported by any expert testimony or documentary evidence tending to support or confirm his contention. He had no evidence tending to contradict the County's and District's experts, all of whom indicated there would be no adverse impact on the environment or water resources as a result of the instant permit. Similarly, neither Petitioner offered any evidence of a demonstrative nature that would draw any connection between the proposed permitted withdrawals and potential salt water intrusion and water level drawdown in their wells. The County introduced construction permits issued by its own health department covering 8 of the 12 wells which have been drilled on the Carlton Reserve as test wells. These wells were clearly sunk pursuant to an agreement between the District and the County's public health unit which delegates authority for water well construction permitting to the County. Taken together the documentation indicates that these 12 wells on the Reserve were installed and permitted pursuant to and consistent with appropriate permitting processes, and the testimony of Mr. Bassarab, the County's expert who oversaw the installation of the wells, reflects they are appropriately grouted and sealed. Therefore, there will be no mixing of lower quality water from the lower portion of the Floridan aquifer with the better quality water from the upper portion of that aquifer. The County's evidence clearly refutes the allegation by Mr. Bishop that the 12 test wells currently existingon the Carlton Reserve were neither permitted nor inspected as required by the District. County Commissioner Hill, who testified on behalf of the Petitioners, indicated that the wells applied for here are unnecessary and an inappropriate expenditure of County funds. She claimed there are other valid sources of water available to the County, including that extracted from excavated shell pits and seawater from the Gulf of Mexico which could be treated and desalinated. The Commissioner's comments as to alternate sources are not specifically rebutted. However, she is neither an expert in hydrology or hydrogeology, and her testimony is not persuasive. While other water sources may exist, the better evidence clearly indicates that those sources are not sufficient to meet the County's needs or are otherwise inappropriate for use by the County in sufficient quantity to satisfy those needs.
Recommendation Based on the foregoing Findings of fact and Conclusions of Law, it is, therefore: RECOMMENDED that consumptive water use permit No. 208836.00, providing for authorized quantities as outlined in the intent to issue, subject to conditions contained therein, be issued to Sarasota County.

The Issue The issue in this case is whether the portion of Consumptive Use Permit (CUP) Application Number 97106 seeking an allocation of 499,000 gallons per day (gpd) of groundwater for commercial/industrial uses (supply bulk water to bottling plants) meets the conditions for issuance as established in Section 373.223, Florida Statutes, Florida Administrative Code Rule 40C-2.301, and the Applicant’s Handbook, Consumptive Uses of Water.1 The County does not oppose or contest the portion of the CUP application authorizing use of 6.0 million gpd of surface water for limerock mining operations.
Findings Of Fact The Parties The County is a political subdivision of the State of Florida. The County operates a water supply utility that supplies water for a variety of uses, including providing untreated water, in bulk, for bottling purposes. The County is currently engaged in a long-range planning effort designed to assess water supply demands and sources to supply those demands in the County over the next 50 years. The County also has completed a study of the two major springs in the County (Rainbow Springs and Silver Springs), and the County’s Board of County Commissioners is in the process of enacting certain recommendations contained in the study. The well for the proposed CUP allocation is located on approximately 160 acres in northern Marion County. Hastings and Greene's father owned the property from 1978 until the latter's death. In 1993, the latter's interest was transferred to Greene and two brothers, who now hold title to the property along with Hastings. The District is a special taxing district created by Chapter 373, Florida Statutes, and is charged with the duty to prevent harm to water resources of the District, and to administer and enforce Chapter 373, Florida Statutes, and the rules promulgated thereunder. The District has implemented Chapter 373, Florida Statutes, in part, through the adoption of Rule Chapters 40C-2 and 40C-20, and the Applicant’s Handbook, Consumptive Uses of Water. Historic Uses of Water on the Mine Site Since the 1980s, the property where the proposed withdrawals will occur has been used for mining of limerock and has been known as the “Black Sink Mine." A ten-inch diameter well has been located on the Black Sink Mine property for 35 years. The well was originally used to provide water to augment water levels in canals in and around the Black Sink Mine property. Later the well was used to irrigate watermelons grown on the property before the mining operation began. The limerock mining operation at Black Sink Mine uses approximately 6 million gpd of surface water. The mine pit at the site is divided by an earthen berm that separates a larger, previously mined area from a smaller area where active mining is occurring. Surface water is pumped from the actively mined portion of the pit to the larger, previously mined portion of the pit, to enable mining of the limerock material to be conducted at levels below the water table. Dewatering is necessary in order to remove the limerock. A majority of the property is mined to a depth of 55 feet below land surface. The limerock material extracted from the site is transported by trucks from the site, approximately 100 trucks per day, to various sites across North Florida. The Need for the Proposed Use of Groundwater If mining of limerock continues at the current pace, the limerock material at the Black Sink Mine will be exhausted within a year. Recognizing that the productive use of the property for limerock mining was nearing an end, Greene and Hastings began exploring other potential uses for the property, including use of the existing well on the property for production of bottled water. To explore the feasibility of producing water for bottling from the existing well, in 2004 Greene and Hastings engaged an engineering firm with expertise in water resources to conduct a hydrogeologic study of the mine property and well. The results of the study, showing water of sufficient quality and quantity for production of bottled water, motivated Greene and Hastings to submit the CUP application which was the subject of the hearing. The study also determined that water withdrawn from the well could be marketed as spring water. Greene and Hastings also determined through market research that the demand for bottled water has increased at the rate of ten percent per year for the last 4-5 years and that Florida bottlers were interested in purchasing water from the well on the mine site in bulk for bottling. In order to provide reasonable assurance that the water use proposed by Greene and Hastings is in such quantity as is necessary for economic and efficient utilization, Greene and Hastings must show that the amount to be used is consistent with what would typically be required for the activity being supplied; that the water will be used efficiently with loss or waste minimized; and that there is a demonstrated need for the water proposed for allocation. To demonstrate a need for the 499,000 gpd of groundwater requested in the application for an allocation of 499,000 gpd of groundwater, Greene and Hastings provided letters from two businesses engaged in bottling of water stating an intent to purchase specific quantities of water produced from the Greene and Hastings well should the CUP be granted. One of the letters of intent came from a bottler in Jacksonville, Florida, stating its intention to initially purchase 100,000 gpd of Greene and Hastings’s water. The other was from a bottler in Stuart, Florida, dated January 9, 2006, stating its intention to purchase 125,000 gpd of water from Greene and Hastings within “the next 12-24 months.” Based on these letters Greene and Hastings initially requested an allocation of 200,000 gpd of groundwater for the first year of the permit. Prior to completion of the CUP application, Greene and Hastings learned that because the Stuart bottler’s facility was located outside the geographic boundaries of the District, to transport water from the Black Sink Mine to the Stuart facility would require additional data and information related to inter- district transfers of groundwater. Greene and Hastings elected to reduce the requested allocation for the first year of the permit to 100,000 gpd, relying on the letter from the Jacksonville bottler. Based on the current market demand for bottled water, and based on the fact that there are other bottlers of water within the boundaries of the District purchasing water for bottling, it is reasonable to conclude that Greene and Hastings can sell 499,000 gpd of water from the well on the Black Sink Mine property by the end of the fifth year of the proposed CUP. These facts support the conclusion that there is a need for the amount of water requested by Greene and Hastings. In addition, the permit is conditioned to require a compliance review at five-year intervals during the term of the permit. Should Greene and Hastings not be successful in selling the full 499,000 gpd allocated by the fifth year of the permit, the District has the ability as part of the five-year compliance review to modify the permit to reduce the allocation based on the amount of water actually used for bottled water. Efficiency of the Proposed Use of Water The production of water in bulk for shipment to a bottler is a highly efficient use of water. There is very little if any water lost in the withdrawal and loading of the water; almost all the water goes to the end product. The evidence establishes that the use proposed by Greene and Hastings is an efficient use of water. Potential Impacts from the Proposed Groundwater Allocation The source of the groundwater proposed for use by Greene and Hastings is the Floridan aquifer. Because there is no confining layer in the vicinity of the Black Sink Mine that would retard movement of water between the Upper Floridan aquifer and the surficial aquifer, both the Upper Floridan aquifer and the surficial aquifer essentially behave as one unit. Thus, any drawdown in the surficial aquifer associated with groundwater withdrawals at this location will be the same as the related drawdown in the Upper Floridan aquifer as a result of groundwater withdrawals. The Floridan aquifer is capable of producing the amount of groundwater requested by Greene and Hastings in the application. To assess the level of drawdown expected to occur in both the Floridan aquifer and the surficial aquifer as a consequence of the proposed groundwater withdrawals, Greene and Hastings engaged a consultant, Andreyev Engineering, Inc., to run a groundwater model to simulate the proposed withdrawal and predict the anticipated drawdown. The groundwater model selected for use for this application was the North Central Florida Regional Groundwater Flow Model, a model developed for the District by the University of Florida for use in Marion County and surrounding areas. This model is an accepted and reliable tool for predicting aquifer drawdown associated with groundwater withdrawals at the location of the withdrawals proposed in this application and is used extensively by the District in its CUP program. To simulate the drawdown associated with the withdrawal of 499,000 gpd from the Florida aquifer, Greene and Hastings’s consultant inserted a pumping well in the model grid where the Black Sink Mine is located. The model then simulated pumping from the well at 499,000 gpd. The model results are graphically depicted on maps showing drawdown contours overlain on the Black Sink Mine Site, illustrating the level of drawdown in the aquifer and the distance the level of drawdown extends out from the well site. The model predicts a drawdown of 0.03 feet in the Floridan and surficial aquifers in the immediate vicinity of the well on the Black Sink Mine property, and a drawdown of 0.02 feet in the Floridan and surficial aquifers extending out to a distance of approximately 5,000 feet from the well, less than 1/3 of an inch of drawdown. The model results represent a reasonable estimation of the drawdown that will occur as a consequence of withdrawal of 499,000 gpd of groundwater at the Black Sink Mine as proposed in the application. The impact of the 0.02-0.03 foot drawdown predicted by the model was variously characterized by the experts who testified at the final hearing as “not practically measurable,” an “insignificant impact,” “very small,” or “de minimus.” The use of water proposed by Greene and Hastings will not cause significant saline water intrusion, nor will it further aggravate any existing saline water intrusion problems. The use of water proposed by Greene and Hastings will not induce significant saline water intrusion to such an extent as to be inconsistent with the public interest. Because the predicted drawdown is so small, it will not interfere with any existing legal uses of water. Neither will the predicted drawdown cause serious harm to the quality of the source of the water proposed for use by Greene and Hastings. With regard to the issue of interference with existing legal users, the County argued that the District should have considered whether there is sufficient groundwater available to meet all projected needs for water in the County during the 20- year term of the permit, as well as the additional cost County citizens will need to bear to secure alternative water supplies as a result of any future shortfalls in available groundwater. The County projects, based on planning estimates, that use of groundwater to supply all anticipated uses of water in the County will be limited within 20-30 years from the present. Such “limits” would not become an issue until after the Greene and Hastings permit expires. Thereafter, water users in the County will have to rely on alternative water sources, conservation, reuse of reclaimed water, and surface water. The anticipated growth in demand in the County’s planning estimates includes anticipated growth in the commercial/industrial category of uses. The County’s estimated limits on groundwater use will occur whether or not the CUP requested by Greene and Hastings is approved. The District does not base its permitting decisions on a pending CUP application on the possibility that the source of water may become limited at some future time for water uses not presently permitted, provided the application meets all permitting criteria. The District allocates water for recognized beneficial uses of water, such as commercial/industrial uses, as long as the water is available and the application meets District criteria. The District allocates water as long as an allocation does not cause harm to the resource. Based on these facts, the proposed use of water by Greene and Hastings will not interfere with any existing legal use of water. No Evidence of Economic or Environmental Harm Because the predicted drawdown associated with the proposed use of water is so small, and because no impacts are anticipated on any surrounding properties or water uses, Greene and Hastings have provided reasonable assurance that any economic harm caused by the proposed use has been reduced to an acceptable amount. For purposes of determining whether an applicant has provided reasonable assurance that any environmental harm caused by a proposed use of water is reduced to an acceptable amount, the District examines modeling results showing the level of drawdown predicted for the use and also examines the resources in and around the site of a withdrawal to determine the likely impact of the drawdown predicted for the withdrawal on those resources. The District’s environmental scientists examined the Black Sink Mine site and the surrounding landscape and determined that, based on the characteristics of the landscape in and around the site of the proposed withdrawal and based on the negligible drawdown impact predicted for the proposed water use in both the Floridan and surficial aquifers, there will be no environmental harm resulting from the allocation of groundwater contained in the CUP. The use of water proposed by Greene and Hastings will not cause damage to crops, wetlands, or other types of vegetation. The use of water proposed by Greene and Hastings will not cause the water table to be lowered so that stages or vegetation will be adversely and significantly affected on lands other than those owned, leased, or otherwise controlled by Greene and Hastings. The CUP will not use water that the District has reserved pursuant to Section 373.223(3), Florida Statutes, and Rule 40C-2.301(4). No Impact on Established Minimum Flows or Levels No minimum surface or groundwater levels or surface water flows have been established by the District pursuant to Rule Chapter 40C-8 for any of the water bodies in Marion County that may be affected by the proposed water use. The closest water body for which the District has established a minimum flow is the St. Johns River at the State Road 44 bridge located more than 50 miles from the Black Sink Mine property. The closest water body for which the District has established a minimum level is Star Lake in Northwest Putnam County, more than nine miles from the mine site. Because of the distance of these water bodies from the withdrawal site and because of the negligible drawdown expected to be caused by the proposed use of water, the use will not cause an established minimum flow or level to be exceeded during the term of the permit. Other Reasonable-Beneficial Use Considerations All available conservation measures that are economically, environmentally, and technically feasible are proposed for implementation in the application by Greene and Hastings for the uses proposed by them. Greene and Hastings submitted to the District, as part of the application, a conservation plan that complies with the requirements of A.H. Section 10.3(e). Reclaimed water, as defined in the District’s rules, is not currently available to be used in place of the water proposed for use by Greene and Hastings in the application. The use of water proposed by Greene and Hastings in the application will not cause or contribute to a violation of water quality standards in receiving waters of the state. The use of water proposed by Greene and Hastings in the application will not cause or contribute to flood damage. The Use is Consistent With the Public Interest With regard to the determination of whether reasonable assurance was provided that the proposed use is consistent with the public interest, the County contends that: 1) Greene and Hastings must show that any necessary approvals required by the County’s Comprehensive Plan and/or its LDRs for use of the site for producing bottled water have been obtained; 2) that the District did not properly consider the effect of existence of lawn watering restrictions affecting citizens in the County in evaluating the application; and 3) that the District should have considered the amount of money the applicant may stand to gain from the use of the water requested in the application. In examining whether an application is consistent with the public interest, the District considers whether a particular use of water is going to be beneficial or detrimental to the people of the area and to water resources within the state. In this inquiry, the District considers whether the use of water is efficient, whether there is a need for the water requested, and whether the use is for a legitimate purpose; and the inquiry focuses on the impact of the use on water resources and existing legal users. Sale of water for bottling for human consumption is recognized by the District as a legitimate, beneficial economic enterprise. Use of water for human consumption is among the highest and best uses permitted by the District. For reasons outlined above in the Recommended Order, there are no detrimental impacts that will result from this use of water. The District does not consider whether local government approvals have been obtained prior to issuance of a CUP for purposes of determining whether the application is consistent with the public interest. Neither does the District consider impacts related to local roads from trucks transporting the water or other impacts not related to water resources. No such requirements are included in the District’s adopted permitting criteria. There are no water shortage orders in effect in the District at present. In evaluating a CUP application, the District considers whether its permitting criteria will be met during periods of normal weather as well as during periods of drought. Withdrawals authorized in CUPs can be restricted by order of the District during periods of water shortage, such as droughts. Thus, the possibility of a water shortage order being entered in the County in the future, or the fact that such orders may have been in effect there in the past, does not mean the application is not consistent with the public interest. The District critically examines the efficiency of all water uses for purposes of enacting its regulatory requirements regarding CUPs and in evaluating CUP applications. The District has adopted restrictions on landscape irrigation (which apply to all such users throughout the District’s jurisdiction, not just in Marion County) limiting landscape irrigation to no more than two days per week. The limitations on landscape irrigation exist because this type of use has been determined to be a highly inefficient, wasteful use of water without such restrictions. By contrast, the use of water proposed by Greene and Hastings is a highly efficient use of water, resulting in little or no loss or waste of water. The District does not consider the level of financial gain or benefit an applicant will derive from a permitted use of water for purposes of determining whether the proposed use is consistent with the public interest. Most, if not all permitted users of water derive some level of economic benefit from the water they use, and the District’s rule criteria do not provide standards for evaluating such gain or that otherwise limit the amount of such gain. For the foregoing reasons, the Applicant has provided reasonable assurance that the use of water proposed in the application is consistent with the public interest. Groundwater is the Lowest Quality Source for this Use The County contends that groundwater is not the lowest quality source of water available for the use proposed by Greene and Hastings, in that surface water from the mine pit on the site could be treated and used for bottling in place of groundwater. From the testimony, it is clear that Greene and Hastings’s ability to market water for bottling from the Black Sink Mine is dependent on such water being capable of being labeled as spring water, and on such water being delivered without having gone through any treatment processes. The testimony also establishes that because of the connection between the surficial aquifer and the Upper Floridan aquifer at the site, using surface water instead of groundwater to supply the proposed use would result in little if any reduction in impacts to the Floridan aquifer. More importantly, because the application proposes use of water for direct human consumption, the District’s rules do not require use of a lower quality source of water. For the foregoing reasons, groundwater is the lowest quality source of water suitable for use for bottled water for human consumption. The District’s Noticing Was Adequate and Appropriate The District provided notice of its receipt of the Greene and Hastings CUP application by publishing notice in the Ocala Star-Banner, a newspaper of general circulation in Marion County, on January 25, 2005, with an amended notice being published on February 16, 2005, and also by letters to the County dated January 20, 2005, and February 10, 2005. In each notice, the location of the proposed use was identified by section, township, and range. The County responded to the notices by sending a letter of objection to the application dated February 14, 2005. Thus, the County received sufficient information regarding the location of the proposed use to enable it to prepare and file a letter of objection to the application, and suffered no prejudice as a consequence of the notice. The District provided personal notice of its intent to issue a CUP to Greene and Hastings by letter dated April 5, 2006. In this notice, the location of the proposed use was identified by section, township, and range. The County responded by filing petitions that have resulted in this proceeding. Thus, the County received sufficient notice of the location of the use addressed in the District’s intent to issue to enable it to initiate administrative proceedings regarding the permit, and suffered no prejudice as a consequence of the notice.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the District enter an order granting CUP No. 97106 to Greene and Hastings with the conditions recommended in the District’s Technical Staff Report. DONE AND ENTERED this 9th day of January, 2007, in Tallahassee, Leon County, Florida. S J. LAWRENCE JOHNSTON Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 9th of January, 2007.
The Issue The issue is whether the 100 foot separation of respondents/applicants sewage treatment plant from the surface water management system is adequate.
Findings Of Fact Based upon all of the evidence, the following supplemental findings of fact are determined: Background Respondents/applicant, John D. Remington and Bolton S. Drackett (applicants), are the owners of record of approximately two thirds, or around 2,700 acres, of Keewaydin Island (Key Island), which lies just south of the mainland portion of the City of Naples, Florida. In conjunction with a planned luxury development of forty-two homes on Key Island, applicants have filed an application with respondent, South Florida Water Management District (District), seeking the issuance of a permit authorizing the construction and operation of a surface water management system (system) through which stormwater runoff from the project will be directed and controlled. Petitioner, Florida Audubon Society (FAS), has initiated this proceeding to contest the issuance of a permit. In an earlier and separate proceeding (DOAH Case No. 90-2415), applicants applied for a permit from the Department of Environmental Regulation (DER) to construct a wastewater treatment plant (plant) to serve the planned development. The permit was issued on January 2, 1990, and because all appeals by FAS in Case No. 90-2415 have been concluded, that proceeding is now final. Although the wastewater treatment plant has not yet been constructed, the parties agree that it will be situated more than one hundred feet from the surface water management system. This distance (100 feet) is the minimum amount of space allowed by District rule between the plant and system. Even so, the purpose of the remand proceeding is to determine whether that amount of separation is adequate. Thus, the factual issue here is whether the treated wastewater from the plant and filter fields will enter the surface water management system and cause a violation of applicable water quality standards and other relevant District criteria. In support of their respective positions on this issue, the parties have presented the testimony of a number of experts. In resolving the conflict in their testimony, the undersigned has accepted the more credible and persuasive testimony which is embodied in the findings below. A Brief Description of the Development and System The proposed development and surface water management system were described in detail in the prior recommended order entered in this case. For purposes of this Supplemental Recommended Order, it need only be noted that Key Island now has a lodge, guest quarters and recreation facilities, all presently served by septic tanks. Access to the island is provided by motor launch from an existing shore station. Subaqueous utility crossings from the mainland provide electric power and potable water to the island. The planned development includes the construction of forty-two large luxury homes and an expansion of the lodge facilities to accommodate the needs of the new residents. The homes will be built in phases with approximately ten to be built in the first year. The entire project may take as long as seven or eight years to complete. The proposed surface water management system was designed to handle a seventy-five residential unit development. However, by virtue of a reduction in size imposed by the City of Naples, the project has been reduced to forty-two homes. Even so, the capacity of the system has not been downsized. Therefore, the system as designed will more than accommodate all proposed development on the island. The development area has been divided into seven surface water management basins based upon seven existing natural water sheds on the upland portion of the project. Each basin will have a system of inlets, culverts and swales which will direct runoff to control structures. The dry swales are approximately one foot deep and five to ten feet wide and run parallel on both sides of the cart paths that link the various portions of the project. The cart paths, which will be at an elevation of 5.5 feet above mean sea level (NGVD), will have culverts running underneath to aid in maintaining the natural flow of water and limit impounding of water. The swale bottoms are designed to be one foot below the cart path elevation, or at 4.5 feet NGVD, and will be dry, except during significant rain events, because they are designed so that the bottom of the swale is at least one foot above the average wet season water table. Both the cart paths and swale system utilize a design system that is common to residential developments. Once the water reaches a specified height, it goes over the control structure and is discharged downstream into spreader swales from which the water is dispersed into either interior, low wetland areas or into two artificial lakes (7.3 and 1.0 acres in size) created for wet detention. Basins one, two, three, four and seven are designed to treat water quality by the dry detention method, that is, by the unlined swales that parallel cart paths, while water quality is accomplished in basins five and six by best management practices and wet retention, that is, the two artificial lakes. The Wastewater Treatment Plant The DER permit was issued on January 2, 1990, and carries an expiration date of January 2, 1995. It authorizes applicants to: construct a 0.035 MGD extended aeration process wastewater treatment plant with reclaimed water to dual absorption fields located at the project site as depicted on Wilson, Miller, Barton, Soll & Peek, Inc. design drawings, project number 6270, sheets 1 thru 5 of 5, dated March 20, 1989, revised October 16, 1989 and received October 19, 1989. The design drawings were submitted in support of construction application, engineering report, hydrologeolic characteristics and hydraulic modeling for effluent disposal report and related documents, dated March 20, 1989. The hydraulic capacity of the plant is limited to 0.030 MGD based on the reclaimed water disposal system. The collection system shall not exceed the 0.030 MGD hydraulic capacity as well. The wastewater treatment plant is designed to meet all DER water quality, health and safety standards. For example, the plant must achieve 90% removal of biological oxygen demand (BOD) and 90% removal of total suspended solids from the raw wastewater, or effluent levels below 20 parts per million for BOD and 10 parts per million suspended solids, whichever is more stringent. The plant must also have twenty-four hour detention in the aeration chamber and four hours detention in the clarifer. Further, a chlorine chamber contact time of fifteen minutes is required. In addition, DER has issued the permit with certain specific conditions. Among others, these include standards as to effluent chlorine residuals, the requirement that a professional engineer inspect the construction, operation requirements, sampling schedules, defined perameter levels, and the establishment of a hydraulic plant load (permitted maximum daily flow) at 30,000 gallons per day. By issuing the permit, DER has concluded that up to 30,000 gallons per day of sewage effluent can be treated and disposed of by the plant filter fields without violation of applicable DER water quality, health and safety standards. The wastewater treatment plant will be located on a centralized utility site within basin seven of the system. There are also gravity sand filters and a drainfield effluent disposal system located in basin six, which is the northeastern corner of the project. The plant will provide a high degree of treatment and disinfection for the effluent before it is discharged to the filter field. The filtered (treated) effluent will flow by gravity main to the filter fields located in an adjacent basin. Two filter fields will be used in disposing of the treated wastewater effluent. Constructed as sand mounds at a grade level of two or three feet above the existing island elevation, each filter will have dimensions of twenty feet wide and four hundred feet long. The filter fields will be constructed as a bed of gravel wrapped in filter cloth and placed within a mound of soil. A perforated four-inch pipe will be installed within the gravel bed at 5.5 feet NGVD to distribute the effluent through the filter beds. The effluent will then percolate downward and laterally away from the bed and into the groundwater table. At that point, the effluent will become indistinguishable from the groundwater Because the total daily flow will be pumped alternately into one part of the two sections of the drainfield, this allows one filter field to "rest" for a seven-day period during the use of the other filter field, thereby avoiding saturation. Therefore, the average theoretical maximum input into a filter field over a one year period at the plant's maximum capacity is 15,000 gallons per day. The plant was designed and permitted for maximum daily flows at all times of the year. However, the actual operating conditions will reflect significantly less flows due to the seasonality of the population and occupancy levels. More specifically, the plant was designed and permitted for seventy- five dwelling units and ancillary uses with an estimated maximum design flow of 28,450 gallons per day. The approved planned development will contain only forty-two dwelling units and ancillary uses with a maximum design flow of 21,200 gallons per day. Therefore, the permitted plant will treat the wastewater to a higher level due to the reserve capacity, and the plant will rarely be used at over fifty percent of its available capacity. Revised projected wastewater flows will range from daily loads of 2,325 gallons per day during the months of August and September to a high of 15,137 gallons per day during the month of February. This projected usage is consistent with historical occupancy and usage trends in the Naples area which show that occupancy of homes is at its peak during the dry season (the cooler winter months) and substantially lower during the wet season (the hot summer months). Applicants' projected wastewater flows are found to be reasonable and are hereby accepted. In making this finding, the undersigned has rejected the contention by FAS that the daily wastewater flows will be higher than that projected by the applicants and the plant will operate at maximum capacity for sustained periods of time. The system plans reflect that there will be swales within basin six located between one hundred ten and one hundred twenty feet to the west of the filter fields. These swales run parallel along a cart path and flow to the north discharging into an artificial lake at the north end of the project. The swales in this basin have a bottom elevation of 4.5 feet NGVD and decrease to an elevation of 3.5 feet NGVD at the point of discharge into the artificial lake. Adequacy of Separation Between Plant and System Rule 40E-4.091, Florida Administrative Code, adopts and incorporates by reference a document known as the "Basis for Review for Surface Water Management Permit Applications within the South Florida Water Management District - September 1989" (Basis for Review). Section 3.2.2.8 of the Basis for Review reads as follows: Sewage treatment percolation ponds. Above ground pond dikes shall not be within 200 feet of water bodies or 100 feet of dry detention/ detention areas. Additional calculations by the applicant may be necessary in unusual cases requiring deviations from these dimensions. The purpose of the above section is to provide adequate separation between above-ground percolation ponds and surface water management systems in case the percolation pond dike fails. For example, above grade percolation ponds contain large volumes of sewage treatment plant effluent. If a pond dike should fail, a large portion of effluent would be quickly released into the adjacent ground. The minimum 100-foot separation is designed to provide adequate distance for percolation into the ground prior to infiltrating the surface water management system. However, filter fields contain lesser volumes of effluent than do percolation ponds, and should a filter field fail, the effluent will trickle out the side of the field with a much lower rate of effluent release than from a failed pond dike. In accordance with the District rule, applicants have proposed to locate the surface water management system more than one hundred feet from the wastewater treatment plant and filtration beds. Even though the rule standards have been met, the purpose of this remand proceeding is to determine whether that amount of separation is adequate to prevent adverse impacts to the water quantity and water quality functions of the system from the operation and location of the filter fields. The Computer Models As a part of their application filed with DER in 1989, applicants' witness Missimer prepared and submitted a report known as "Hydrogeologic Characteristics and Hydraulic Modeling for Effluent Disposal at Keewaydin Club". The report was based on a computer model known as "Modflow" and was designed to show the increase in elevation of the water table for a loading rate of 30,000 gallons per day alternating between the two filtration beds. The purpose of the modeling analysis filed with DER was to investigate whether the plant would continue to discharge effluent to the drainfields under the most extreme conditions. The model demonstrated that the effluent discharge would not be impaired even under conditions that are beyond any reasonable or probable operating conditions. After reviewing the model, DER accepted those results and issued a permit. Utilizing in large part the underlying assumptions and parameters of the Missimer model, and without performing any independent field evaluation on the site, FAS witness Chin ran the model to investigate the impact of the operation of the plant on the system. Because the model used by Dr. Chin was not constructed for the design of a surface water management system, but rather was constructed for the purpose of designing an adsorption field, without modification it provided a more than worst case scenario of impacts associated with the operation of a plant. In this case, Dr. Chin utilized the ultra- conservative assumptions used in designing the adsorption field and made no revisions to the model. Thus, it is found that the model as used by Dr. Chin, and any conclusions drawn from the model alone, are not a sufficient or reasonable basis for evaluating the impact of the plant on the system. The model used by Dr. Chin is not representative of the natural occurring conditions on the island or the reasonably expected plant flow rates. Moreover, in developing the worst case scenario, as opposed to reasonable expectations, both the Chin and Missimer models incorporated the simultaneous occurrence of certain conservative assumptions including an impermeable flow boundary, a year round wet season water table elevation, a conservative rate of transmissivity, and a constant rate of evapotranspiration. The use of these assumptions caused the model output to grossly overstate the effects of the plant on the system in the following manner. First, by assuming a flow barrier on the island, the model had the effect of overestimating the height of the groundwater mound from operation of the plant than would occur if no boundary were used. Second, the assumption of a year-round wet season groundwater level is unrealistic since groundwater levels fluctuate seasonally, receding to near zero NGVD on the island during the dry season. Thus, the model overestimated the height of the groundwater level. Further, by using only the upper ten feet of the water table aquifer in calculating the rate of transmissivity, the model incorporated a much lower rate than would be attained had the entire thickness (74 feet) of the aquifer been used. This also resulted in an over-estimation in the height of the mound from the operation of the plant. Finally, by assuming a constant rate of evapotranspiration, the model "grossly exaggerated" the impact to the groundwater level from operation of the plant. In reality, as the water table increases, the loss of water from evapotranspiration increases significantly and constitutes a major output of a water budget. Besides the foregoing assumptions, the Chin model also assumed a continuous loading rate of 30,000 gallons per day for a period of up to one year. While the District should properly consider the permitted flow rate of the plant in evaluating a worst case of potential impact, there was no evidence substantiating any likelihood of the plant actually producing 30,000 gallons per day for 365 consecutive days in conjunction with all other conservative assumptions discussed above. The more reasonable and accepted method of analyzing the impact of plant flows is to examine the peak month's average day flow over a six-month period. As noted earlier, for the proposed forty-two units, the peak day flow is estimated to be approximately 21,200 gallons per day. Therefore, it is highly probable that actual flow rates will be much lower than the maximum plant capacity of 30,000 gallons per day. By failing to use the more reasonable and realistic reduced flow rates, the Chin model overestimated the elevation of the groundwater level from the operation of the plant. In contrast, the Missimer analysis demonstrates that it is extremely unlikely that the plant output will ever elevate groundwater to the extent that it would reach the system swales by either surface water or groundwater flow. The foregoing modeling assessments, including the criticisms of the Chin model, were concurred in by the District expert. Water Quantity Impacts There is no credible evidence to support a finding that the operation of the plant will adversely impact the ability of the system to provide adequate flood protection and drainage. Indeed, the more credible evidence shows that an alteration of existing drainage patterns will not occur by virtue of the operation of the plant, and the post-development discharge rates will not exceed the pre-development discharge rates. Therefore, the undersigned's previous finding that applicants have provided reasonable assurance that the the system provides adequate protection and drainage is not altered after considering the operation and location of the plant. There is insufficient credible evidence to support a finding that the plant's operation will adversely impact the system functions in such a way as to cause adverse water quantity impacts on receiving waters and adjacent lands. Indeed, the post-development discharge rate approximates the pre-development discharge rate on receiving waters, the ultimate receiving water body (the Gulf of Mexico) has an infinite capacity to receive water, and there are no adjacent lands subject to flooding from discharge of the system regardless of whether there is any impact of the plant on the system. There is no credible evidence to support a finding that the plant will cause the system to have an adverse impact on surface and groundwater levels and flows. Rather, the more persuasive evidence shows that the plant's operation will not result in groundwater elevation in the area of the system that would cause the impoundment of water or prevent the percolation of water into the soil. In addition, the overflow levels for control structures will operate as designed to insure against over-drainage or flooding. Finally, the operation of the filter fields will not cause adverse impacts on surface and groundwater levels and flows. Water Quality Impacts The operation of the plant will not impair the water quality functions of the system. This is because the swales will continue to detain the first flush of run-off allowing the majority of the suspended solids and other pollutants to settle out regardless of the operation of the plant. Further, in the unlikely event the treated wastewater effluent reached the system, it would be indistinguishable from the stormwater or rainfall due to the high level of treatment from the plant, the filter fields and dilution from groundwater and rainfall. The operation of the plant will not cause adverse water quality impacts on the receiving waters. In making this finding, the undersigned notes initially that the plant is permitted by DER, and therefore it is assumed to comply with all DER water quality standards. Second, there is no evidence that the system will impact the operation of the plant. In the event the groundwater mixed with treated effluent resurfaces, there would be no adverse impact to the surface water quality. This is because the treated effluent from the plant exceeds state water quality standards. Once the treated effluent becomes a part of the groundwater, it is unlikely that it will resurface again in the areas of the swales, which are more than one hundred ten feet away. Indeed, in order for the groundwater with effluent to travel that distance, it would have been in the groundwater system for at least one hundred days. This period of time is more than sufficient for the denitrification and adsorption processes to remove all nutrients. Even if the worst case scenario became a reality and the groundwater reached the swale bottoms, it would only result in a wetting of the ground and would not be of sufficient quantity to create a flow of water in the swale to travel off-site impacting a receiving water. In any event, at that point, any groundwater resurfacing that distance away would no longer be effluent. Finally, during abnormal conditions, such as a hurricane or large storm event, the groundwater may rise to the surface and mix with the surface water and enter the system. However, any effluent already significantly diluted under normal circumstances would be indistinguishable from the stormwater or rainfall. Adverse Environmental Impacts There is no credible evidence that the operation of the plant filter fields will adversely impact the system in such a manner as to cause an adverse environmental impact. In so finding, the undersigned rejects the contention that the system will act as a conduit for treated effluent to travel off-site to the ponds, marsh, mangrove areas or receiving waters. The evidence shows that the design of the filter fields and high permeability of the island soils will prevent the surface flow of effluent to the system swales. The elevation of the swales above the groundwater table level will prevent the introduction of effluent into the swale system. In the unlikely event the groundwater reaches the bottom elevation of the swale, there would be no significant environmental impact because the quality of effluent would be indistinguishable from the groundwater due to the high level of treatment and dilution, and such water would still be further treated by the system before discharge to receiving bodies. The location of the plant and system will not have an adverse impact on the gopher tortoise population on the island. Rather, the system should enhance the gopher tortoise population by providing mananged land with vegetation suitable for gopher consumption. Further, the general development on the island will reduce the number of raccoons which prey on gopher eggs and young gophers. Miscellaneous During the remand hearing, FAS presented evidence concerning the impact of tides and mean sea level rise and saline lakes on the island. This evidence was essentially the same as that presented in the prior hearing and was rejected in favor of the more credible evidence presented by the applicants on this issue. Nothing was presented during the remand hearing which would alter these prior findings. During the hearing, and in response to a question by District counsel, witness Missimer agreed it would not be unreasonable to install a few monitoring wells to insure that the system is operating properly. Because this requirement is not unreasonable, will serve a valuable purpose, and has been utilized by the District as a special condition on numerous prior occasions, it should be incorporated into the permit conditions. Even though the evidence clearly shows that seasonal tidal fluctuations would not have an adverse impact on the functioning of the system, if such a tidal incursion were to occur, the placement of a check valve device on the water control structures would prevent sea water from flowing back into the system. Such a device would be a minor addition to the system, would not otherwise affect its design, and if deemed necessary by the District, should be incorporated into the permit conditions. Prior to hearing, the District retained the services of an outside consultant to assist it in preparation for trial. The consultant did not testify at final hearing and prepared no reports. He did make several computer runs, none of which are a part of this record. Among other things, District witness Rogers relied upon the computer runs in formulating his opinion on the issue presented on remand.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a final order be entered granting the requested permit in accordance with the agency's proposed agency action dated March 28, 1990. DONE and ENTERED this 22 day of March, 1991, in Tallahassee, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22 day of March, 1991.
The Issue The issue in this case is whether the Southwest Florida Water Management District (District) should issue to Century Realty Funds, Inc. (Century) Environmental Resource Permit (ERP) No. 44000227.002 (the ERP), which would modify Management and Storage of Surface Waters (MSSW) Permit No. 400227.000 (the Permit) and Stormwater Exemption No. EO1481, issued by the District to Century in July 1985 for construction of a surface water management system for Angler's Green Mobile Home Park located in Mulberry, Polk County, Florida.
Findings Of Fact The District issued Management and Storage of Surface Waters (MSSW) Permit No. 400227.000 and Stormwater Exemption No. EO1481 to Century in July 1985 for construction of a surface water management system for Angler's Green Mobile Home Park (MHP) located in Mulberry, Polk County, Florida. Angler’s Green MHP Angler’s Green MHP is an 83-acre residential golf course development of approximately 385 homes located off of State Road 37 near Mulberry. Residents at Angler’s Green own their own mobile homes and lease the residential lots pursuant to annual leases expiring December 31 of each year, with guaranteed renewal conditioned upon owner compliance with the terms and conditions of the lease. Prior to being developed as a mobile home park, the property which is now Angler’s Green MHP was part of a phosphate mining operation and was reclaimed under a phosphate mining land reclamation plan approved by the Florida Department of Natural Resources and a reclamation contract dated September 4, 1984. Final contours of the Angler’s Green site were made in accordance with the approved reclamation plan. After reclamation contouring, a 23-acre manmade (former phosphate mine pit) lake remained in the northeast quadrant of the Angler's Green site. The resulting lake had a finger arm (bay or cove) extending from the southwest corner of the main body of the lake, oriented in a north-to-south direction and located west of a peninsula of land extending into the northwest part of the lake from the north. The lake also had a short, narrow canal leading into the main body of the lake from the south; the canal connected at a right angle to longer narrow waterway to the south of and extending parallel to the main body of the lake in an east-to-west orientation. There also were two smaller ponds on the property after reclamation contouring. After reclamation, surface water onsite generally flowed westerly and discharged from the property to a railroad ditch along the western boundary of the property. The recorded post-reclamation, pre-development water level for the 23-acre lake, as indicated on the site grading plans, was around 127.1 to 127.8 feet above Mean Sea Level (M.S.L.). The 1985 Permits On July 10, 1985, the District issued MSSW Permit No. 400227.000 and Stormwater Exemption No. EO1481 to Century to authorize the construction of a surface water management system for Angler’s Green. The MSSW Permit had an expiration date of July 10, 1988. As designed, the permitted Angler’s Green surface water management system was to route internal stormwater runoff to swales, detention ponds, and catchment areas before discharging through a sidebank sand filtration system (a berm approximately 300 feet long containing an 8” perforated drain pipe covered by a filter fabric and sand filter material) to receiving waters at the northwest corner of the property. The permitted system was designed with five drainage areas known as Basins A through E. Basin A was in the southeast quadrant of the site; Basin B was to its east in the southeast quadrant of the site; Basin E was to the north of Basin A and included the 23-acre former phosphate mining pit reclaimed as an artificial lake, which was referred to as “Lake E” or sometimes “Pond E"; Basin C was to the west of Basin E; and Basin D was to the west of Basin C and to the north of Basin B. The two smaller ponds on the property were designated Pond C-1 and Pond B-1 and were located in Basin C and Basin B, respectively. Basin D was in the northwest corner of the site; the discharge structure was in the northwest corner of Basin D. As the system was designed, stormwater from Basin E would appear to sheet flow naturally into Lake E; stormwater from Basin A would appear to flow naturally to the southwest, away from Lake E, but the system routed the water from the southwest corner of Basin A to the western end of the waterway on Lake E through an underground pipe. Stormwater from Basin B was to flow to and be retained in Pond B-1; as the system was designed, surface water was not designed to discharge offsite from Basin B. As designed, Lake E served as a detention pond for water from Basin E and Basin A. It was to have a control structure (CS-1) in the arm of Lake E that would produce a seasonal fluctuation range of two feet, from 127.5’ above M.S.L. to 129.5’ above M.S.L. Stormwater discharging from CS- 1 was to be conveyed by pipe to Pond C-1, where it was to mingle with surface water draining from Basin C. When full, Pond C-1 would cascade into the golf course area in Basin D and, as necessary, in a portion of Basin B. After catchment and detention in the golf course area, overflow was eventually and ultimately to discharge offsite through the side-bank sand filtration system in the northwest corner of Basin D. In this manner, the Angler’s Green surface water management system was designed to accommodate the 24-hour, 25- year storm event, which was estimated to produce approximately 8 inches of water in a 24-hour period. It also was designed to comply with the water quality requirements as specified in Florida Administrative Code Chapter 17-25 (1985 Ann. Supp.) by detaining the first half-inch of runoff before discharging it offsite through the sidebank sand filtration system in the northwest corner of Basin D. (All rule citations are to the Florida Administrative Code.) Omission of the Stangls During the review process, the District noted from drawings submitted as part of Century's MSSW Permit application that the project area did not include approximately the eastern third of the main body of Lake E. District staff brought this to Century's attention in a request for additional information (RAI) and stated: "If possible, you should obtain a perpetual right to operate and maintain the lake from other owners." In response, Century falsely represented to the District that L. Kirk McKay, a joint venture partner of Century, was the only riparian owner on Lake E and that Century had obtained from him a perpetual right to operate and maintain Lake E as part of the MSSW Permit. In fact, the Stangls owned property on the east side of the lake, including approximately 500 feet of lakefront and contiguous lake bottom. The Stangls and two partners purchased the property from McKay himself in 1979. The Stangls bought out their partners in 1984. The District relied on Century's misrepresentation. The District would not have issued the MSSW Permit to Century if the District had known that Century did not own or control all the land being used for the Permit--specifically, including all of Lake E. See Rule 40D-4.101(1)(d) and (2)(d)6. (1985) (application must include "evidence of ownership or control"). In addition, because the District was unaware of the Stangls' ownership of a portion of Lake E, the District did not require Century to give the Stangls direct, actual notice of the Century's permit application. Instead, the District only required that Century publish notice of the District’s receipt of the permit application. Notice was published on April 3, 1985, in the Lakeland Ledger, a newspaper of general circulation qualified under the terms of Section 50.011, Florida Statutes. But the Stangls did not see the published notice, were unaware of the permit application, and did not ask to participate in the permitting process. The Stangl property adjacent to Angler’s Green remained undeveloped and unoccupied until 1999, when the Stangls' son, John, established a business on the site. Prior to 1999, the Stangls visited the property a couple times a year. They were fully aware of the construction and operation of Anglers Green as a mobile home park across Lake E. During this time, Century leased 385 lots with guaranteed annual renewal conditioned only upon compliance with lease terms and conditions. Amenities under the leases included clubhouse and golf course privileges. At no time before 2000 did the Stangls take any action to challenge the validity of Century's 1985 MSSW Permit. 1985 Surface Water Management Permitting Requirements In 1985, permitting requirements for surface water management systems were divided between two regulatory schemes. Surface water management permits in Polk County were issued by the District under Chapter 373, Florida Statutes, and Rule Chapters 40D-4 and 40D-40, which addressed water quantity and flooding issues for projects greater than and less than 40 acres, respectively. Water quality permits or exemptions from water quality permitting requirements were issued by the Department of Environmental Regulation under Chapter 403, Florida Statutes, and Rule Chapter 17-25 to address water quality concerns. It was not until 1988 that permitting requirements were consolidated into the MSSW regulatory program administered by the District under Rule Chapters 40D-4 and 40D-40. In 1985, the District did not have a Basis of Review (BOR) to specify system design requirements for applicants to provide reasonable assurances that the conditions for issuance of surface water permits were satisfied. Standards and criteria for the design and performance of surface water management systems were contained in Rule 40D-4.301(2) (1985) Under subsection (2)(i) of that rule, projects designed to meet the requirements of Chapter 17-25 [Regulation of Stormwater Discharge] were presumed to meet applicable State water quality requirements. There were no requirements for wet detention pond littoral zones. 20. Under Rule 17-25.03(2)(b) (1985 Ann. Supp.), stormwater management systems for projects with drainage areas less than 100 acres that provided retention or detention with filtration of the first half-inch of runoff were exempt from the permitting requirements of Rule Chapter 17-25. 21. In 1985, District Rule 40D-4.301(2)(j) (1985) allowed for natural areas and existing water bodies to be used for stormwater retention or detention purposes when not in conflict with environmental or public use considerations. Areas that could be considered for this purpose included previously-degraded areas or man-made areas (such as borrow pits). Apparently, the District allowed Century to use Lake E as a detention pond under this provision. Deviations from MSSW Permit Angler’s Green MHP was constructed in two phases, with the first phase completed in 1985, and the second phase completed in 1987. Construction of at least the part of the surface water management system to serve the first phase took place prior to 1985; it was not clear from the evidence whether construction of the part of the surface water management system to serve the second phase also took place prior to 1985, but it clearly took place prior to construction of the second phase in 1987. Condition No. 4 of Century's MSSW Permit required the submittal of a certification that the system was constructed in accordance with the approved and permitted design. But Century did not provide any such certification. Century also never certified to the District that its new stormwater discharge facility, as constructed, continued to qualify for exemption from State water quality requirements. Although the surface water management system was constructed and operating, the District never transferred the 1985 Permit to the operation phase. In several respects, the Angler’s Green surface water management system was not constructed as designed, approved, and permitted in 1985. The pipe to convey stormwater from the southwest corner of Basin A back to the Lake E waterway apparently never was constructed; instead, stormwater from Basin A was routed to Pond B-1. (There also was a berm constructed in Basin A near the southern boundary of the site; but that berm apparently was a visual berm, and there was no evidence that it affected performance of the surface water management system.) Control structure CS-1 (which was supposed to be located in the arm or bay of Lake E) and the pipe to convey overflow from there into Pond C-1 also never were constructed. By the early 1990's, Angler's Green was experiencing flooding in the golf course area in Basin D and B for extended periods of time. In November 1993, the District responded to a complaint of flooding in that vicinity. Upon investigation, the District determined that malfunction of the surface water management system serving Reservation Lakes (now known as Paradise Lakes), a development to the north and downstream of the Angler's Green system, was causing water to back up through the wetlands and the sand filtration system in the northwest corner of the Angler’s Green project. As a result, water overtopped the discharge structure, equalized at levels above the top of the discharge structure's berm, and flooded the golf course for extended periods of time. At some undetermined point in time, an unpermitted pond was dug in Basin D, apparently in an attempt to alleviate flooding of the golf course. In addition, possibly for the same purpose, a pump was installed in Basin D near Pond C-1, and a pipe was installed to convey stormwater from there into Lake E. The sidebank sand filtration system designed to provide filtration of stormwater prior to discharge from the northwest corner of the site does not appear to exist today. It may be present but difficult to see after 15 years of plant growth; or it may have been removed or disturbed as a result of re-grading in the area. However, the evidence proved that the discharge structure was present in 1993, and there is no reason to believe that it was not installed during construction of the surface water management system--i.e., by 1987 at the latest. In addition, at some undetermined point in time, a pipe was installed at the northeast corner of Lake E to convey overflow from Lake E eastward to a drainage ditch located alongside SR 37 to the north of the Stangls' property. No witnesses could testify as to when the pipe to the SR 37 ditch was installed or its elevation. (The District and Century state in their PRO that Map No. 2 in P/I Exhibit 14--an aerial map/survey submitted to the District by Century on August 13, 1990, as part of Century's 1990 Water Use Permit No. 209993.000 application--notes the pipe's elevation as 127.95 feet above M.S.L.; but no such finding could be made from review of the exhibit.) Roads in Angler's Green have inverted crowns to convey runoff from roads, driveways, and roofs away from mobile home lots. Some runoff from these impervious surfaces appears to be directed into a swale on the east side of the site; this swale leads to Lake E. In addition, approximately 12 drains have been installed in or near roads in Angler's Green that convey water through pipes directly into Lake E or Pond C-1. Under current Rule Chapters 40D-4 and 40D-40, road drains connecting impervious surfaces to Lake E would have to be shown on application construction drawings, and separate stormwater calculations would have to be provided in an application. But in 1985 this was not required. Century's calculations, together with flow arrows on drawings showing the direction of stormwater flow towards the detention ponds, were considered sufficient--especially since Century's calculations used a relatively high runoff co-efficient. As a result, the existence of these drains and pipes are not considered to be substantial deviations from the original, approved design. Similarly, approximately 64 roof drains and pipes conveying water from roofs directly into Lake E and Pond C-1 would not be considered substantial deviations from the original, approved design. In addition, these apparently were installed by mobile homeowners over the years, not by Century. From 1985 to 2000, the District did not have occasion to address regulatory concerns at Angler’s Green, except for the complaint of flooding in the golf course area that occurred in November 1993 and a more recent complaint about an area of the golf course that was designed to flood under certain conditions. Otto Stangl’s Complaint and the District’s Response Around November 1999, John Stangl noticed a fish kill in the ditch along SR 37 near the Stangl property. He also was contacted by a governmental compliance officer concerning the fish kill. Upon investigating, John Stangl saw the unpermitted pipe leading from Lake E that was discharging into the SR 37 ditch where the fish kill was observed, as well as the unpermitted pump that was pumping water from the Angler’s Green golf course area through a pipe that discharged into Lake E. In February 2000, Otto Stangl complained to the District about the fish kill and the existence of the unpermitted structures associated with Lake E. Upon receiving Otto Stangl’s complaint, District staff conducted site visits of the Angler’s Green project. Staff observed the unauthorized pump and pipe conveying water from Pond C-1 to Lake E and the unauthorized pipe conveying water from Lake E to the SR 37 ditch. Staff also observed that the Lake E control structure was missing, the pipe to convey stormwater from Basin A to Lake E was missing, and Basin D had been re-graded. In February 2000, the District also became aware of the fact that Century did not have full ownership or control of Lake E. On March 15, 2000, the District issued Century Notice of Non-Compliance and directed Century to either construct the system as designed and permitted or to seek a permit modification. On May 8, 2000, Century submitted a letter application to modify the original MSSW Permit No. 400227.000 by constructing the originally permitted Lake E control structure and pipe conveying water from Lake E to Pond C-1, but in a different location in Lake E than originally permitted due to the existence of homes at the location where these structures were originally planned. The application was subsequently amended to be a formal modification upon Century’s request for further modification to allow Basin A stormwater to flow to Pond B-1 and to expand Pond B-1 and add a control structure and an effluent filtration system. Despite having actual knowledge since at least February 2000 that the Angler's Green surface water management system was built partially on their property, the Stangls did not ask for a hearing on the 1985 Permit. Instead, they awaited the District's consideration of Century's modification application and sought to challenge the District's notice of intent to grant the modification permit issued on October 29, 2001. The District’s Regulatory Compliance Practices In the 1980's, the District appeared to pay little or no attention to construction of permitted projects or submission of required post-construction certifications. Many projects permitted by the District in the 1980’s, such as Angler’s Green, were built and operating although no certifications had been submitted; as a result, the permits issued for these projects never were transferred to the operation phase. Eventually, some projects not built in compliance with issued permits came to the attention of the District, typically through third-party complaints about drainage problems and flooding. By this time, there was a large backlog of issued construction permits for which no required post-construction certifications had been submitted. The backlog of these older projects was so large that the District decided not to initiate an aggressive, systematic, and comprehensive review of all permits for which no required certifications had been submitted. Instead, projects were checked on an ad hoc basis as complaints regarding the functioning of their surface water management systems were registered. When it came to the attention of the District in this manner that a project had been built under an MSSW permit but that no required certifications had been submitted, the District first attempted to secure the required certifications in the form of certified as-built construction drawings and a Statement of Completion, as required by BOR 2.7. In so doing, it was common practice for the District to accept certifications beyond the expiration date on a permit. If projects were substantially completed, the District would not deem the permit as expired simply because the required certifications had not been submitted before the expiration date; and such projects did not lose their status as being permitted. It should be noted that, according to the testimony of the District's expert, William Hartmann, this agency practice was not based on an interpretation of Rule 40D- 4.321(1)(b) (1985) (on duration of construction permits). Rather, the agency practice was to ignore the expiration of the construction permit under those circumstances. In addition, it does not appear from the evidence that the District ever before has faced the situation presented in this case--where a person on whose property part of a surface water management system was built without the person's consent opposes modification and asserts the construction permit has expired. In cases where the agency's practice was applied, if the required certified as-built construction drawings and Statement of Completion could not be provided because the project was not built in accordance with the MSSW permit, the District would require the permittee to either bring the system into compliance with the approved permit designs or obtain a modification of the construction permit. Letter modifications would be accepted when the requested modification would not substantially alter the permit authorization, increase the authorized offsite discharge, impact the environmental features of the project, decrease the required retention/detention, decrease the required flood control elevations for roads or buildings, or decrease pollution removal efficiency. See Rule 40D-4.331(2)(b) (1985). (The current version of the rule adds renewal or extension of the existing permit duration.) Alterations meeting the threshold requirements for a letter modification would be presumed to meet the conditions for issuance for a permit. Otherwise, formal permit modifications would be required. When application is made for a permit modification, the District’s practice is to evaluate those aspects of the surface water management system being modified. Review generally would not extend to the entire system. Permittees seeking to modify their surface water management systems generally are not required by the District to bring the unmodified portions of the system into compliance with current design criteria. Proposed ERP Permit Modification ERP Application No. 44000227.002 seeks authorization to modify portions of the Angler’s Green surface water management system. The specific alterations for which approval is sought are: permanent removal of the existing, unpermitted 18-inch pipe between Lake E and SR 37 roadside ditch; permanent removal of the pump and associated piping conveying water from Pond C-1 to Lake E; installation of the control structure (CS-1), together with installation of pipe to convey water from the control structure to Pond C-1, as designed and approved in the 1985 Permit but different location in the northwest corner of the main body of Lake E; re-grading of the northwesterly portion of the golf course to more closely conform to the original permitted plan and help keep Basin B separate from Basin D; reconstruction of the side-bank sand filter system in the northwest corner of the property, as designed and approved in the 1985 Permit but with a slightly higher invert elevation (122.04 feet above M.S.L.) to prevent water from backing up into Angler's Green from Paradise Lakes again, and with a concrete flume and spreader swale between Pond C-1 and the berm of the side-bank sand filter system; enlargement of Pond B-1; installation of a control structure on Pond B-1; and installation of 100 feet of 6-inch side-bank sand filter discharging to the southwest corner of the property from Pond B-1. By removing the unpermitted pipe to the roadside ditch along SR 37 and by constructing control structure CS-1, with the same control elevations as in the 1985 Permit (albeit at a different location in Lake E), and connecting CS-1 by pipe to Pond C-1 as envisioned in the 1985 Permit, the function of Lake E should approximate its function under the design approved in 1985. Modifying the permitted design to authorize Basin A to flow to Pond B-1 instead of Lake E results in less water flowing to Lake E; these changes will not increase water quantity or quality impacts to Lake E, as compared to the 1985 Permit. As compared to reclamation conditions prior to implementation of the 1985 Permit, water quantity and quality impacts to Lake E would be expected both under the system as designed and permitted in 1985 and as proposed to be modified, by virtue of the similar use of Lake E as a detention pond under either system. Pond B-1 is being enlarged to better accommodate the flow from Basin A. The control structure being added at Pond B-1 will control flow into the swale to the west so as to address water quantity impacts in that area. Stormwater calculations for the revised Pond B-1 demonstrated that the post-development discharge rate will not exceed the pre- development discharge rate, so that there are no concerns for adverse water quantity impacts to receiving waters or adjacent lands or flooding impacts to on-site or off-site property. The historical flows to the west are still maintained. The discharge structure being added at Pond B-1 will account for treatment of the Basin A flow. Based on calculations for revised Pond B-1, the enlarged pond will retain and percolate half an inch of stormwater runoff from the contributing area in 36 hours (which is consistent with current BOR design requirements). The proposed Pond B-1/Basin B modifications, including the routing of Basin A stormwater to Pond B-1, will not adversely affect the quality of receiving waters in that vicinity such that state water quality standards would be violated. Angler's Green is located in the Southern Water Use Caution Area of Polk County. No surface or groundwater levels or surface water flows have been established for this area under Section 373.042, Florida Statutes. The proposed modifications do not involve any works of the District. The proposed modifications are based on generally accepted engineering and scientific principles and employ treatment methods of effluent filtration which involve commonly accepted designs that can be effectively performed and function as proposed. There are no concerns about Century’s financial, legal, or administrative capability to undertake the proposed modifications as specified in the permit, if issued. There are no applicable special basin or geographic area criteria established for this area. Environmental Concerns As with its review of the proposed permit modification for water quantity impacts, the District's review of environmental concerns was limited to review of impacts from the proposed modifications to the original permitted design; unmodified portions of the original permit were not reviewed for compliance with current requirements. An approximately 20 square-foot permanent impact is proposed to Lake E due to the placement of the control structure (SW-1) in the water. A 379 square-foot temporary impact is proposed to Lake E due to the placement of a cofferdam to facilitate construction of the control structure. Temporary impacts to Lake E resulting from the construction of the control structure would be addressed through the use of sediment and erosion controls to prevent possible sedimentation and turbidity that may arise during the construction activity. The placement of a control structure in Lake E would create very minor permanent impacts resulting from the loss of the footprint of the control structure. These impacts would be insignificant. Due to the very minor nature of these proposed impacts, no mitigation would be required, and no loss of wetlands would be required to be recorded on the Wetlands/Surface Water Table. Construction of SW-1 would not adversely impact the value of functions provided to fish and wildlife, and listed species including aquatic and wetland dependent species, by wetlands, other surface waters and other water related resources of the District. No secondary impacts would be expected from construction of SW-1. No unacceptable cumulative impacts upon wetlands and other surface waters would be expected to occur as a result of construction of SW-1. The project area includes .71 acre of herbaceous/forested wetlands (WL-1) in the northwest corner. The potential for secondary impacts is addressed by an existing fence surrounding WL-1, which eliminates concerns for secondary impacts to this wetland area. No adverse impacts would be anticipated to occur to these wetlands, and no adverse secondary impacts to the water resources would be expected to occur as a result of the proposed modifications themselves. The proposed modifications would not cause unacceptable cumulative impacts to wetlands and other surface waters. Class II or Class III waters would not be affected by the proposed modification project. Therefore, Rule 40D- 4.302(1)(c) is not applicable. No seawalls, lagoons or estuaries are involved in this project. Therefore, Rule 40D-4.302(d) is not applicable. The proposed modifications would not be contrary to the public interest. Relocation of a control structure and enhancement of the Basin B portion of the system would create no significant change in impacts. The proposed modifications constitute a slight improvement over water quality from the original permitted design. No threatened or endangered species were identified for Angler’s Green. The proposed relocation and construction of the Lake E control structure, preservation of onsite wetlands in the northwest corner, and re-design of Pond B-1 present no environmental concerns. Consequently, the proposed modifications do not create any potential for adverse effects regarding the conservation of fish and wildlife, including endangered or threatened species or their habitats. The proposed modifications do not adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity. The project area does not involve navigable waters and does not affect the flow of water or cause harmful erosion or shoaling. Hence, Rule 40D-4.302(1)(a)(3) does not apply to this permit modification application. There are no significant historical and archaeological resources involved in this Project. Therefore, Rule 40D-4.302(1)(a)(6) is not applicable to this permit modification application. The proposed modifications would not be contrary to the public interest; they would not adversely affect the public health, safety or welfare or the property of others. No adverse impacts are anticipated to occur as a result of the proposed modifications. The proposed modifications maintain the historic water elevation for Lake E and maintain historic flows for the project area. The modified system should also provide some improvement in water quality.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Southwest Florida Water Management District enter a final order denying Century's permit modification application designated ERP No. 44000227.002.

Findings Of Fact The property has been annexed into the Acme Improvement District (Intervenor) by Special Act of the Florida Legislature. Petitioner purchased 487.7 acres of this tract from private owners in 1954. Subsequently, Petitioner purchased 653.59 acres from the Trustees of the Internal Improvement Fund of the State of Florida on or about March 4, 1960. The balance of the land constituting the property is a 224 acre hiatus tract owned by Marshall Brown with whom Petitioner has an agricultural use agreement. A parcel of Petitioner's land within the property includes a commercial lease to Malrite Corporation for siting a television antenna, consisting of 111 acres in the southeast corner of the property. This area is within the permit application. The tract is otherwise undeveloped and is currently submerged or semi- submerged during much of the year. Petitioner's development plan envisions drainage of this tract and use of the property for cultivation. The property is bounded on the north by Acme Improvement District, on the east by a subdivision called Homeland, on the west by Water Conservation Area #1, also known as the Loxahatchee Refuge, and on the south by undeveloped lands. The boundaries of the Loxahatchee Refuge actually encroach by approximately 300 feet into the property. The property development plan, which is the basis of this application, was prepared by the engineering firm Gee and Jensen. This plan calls for the creation of a 240 acre reservoir of a proposed 3 foot maximum depth. This reservoir would hold the internal stormwater runoff for subsequent agricultural irrigation. Perimeter dikes are to be constructed to prevent surface water runoff from outside areas entering the project and perimeter ditches are to be developed for the deliverance of stormwater runoff from the internal agricultural system to proposed pump stations located at the southwest corner of the development area. On the northwest corner of the proposed reservoir, the existing Acme Improvement District pump station No. 2 would be increased in capacity by 27,000 gallons per minute. Under Acme's charter and its statutory annexation of the property, the proposed reservoir and water management works would become a unit of development controlled by Acme. Under Petitioner's agreement with the hiatus tract owner, Acme would be the exclusive manager and operator of the proposed system, and the property would become an integral part of Acme's water management system. The Acme Water Improvement District is not solely an agricultural support enterprise but serves the various uses which may evolve within its boundaries. The area is currently zoned for limited residential development as well as agricultural. The television antenna facility located on the property is an example of a non-agricultural use. Petitioner's surface water management system is proposed to discharge into the Acme system, which in turn discharges offsite. Discharge into the Acme system is of a limited nature, but the system is designed to discharge for successive days under wet conditions. The design discharge is not limited to an extreme rainfall event but would probably occur during the traditional hydrologic cycle of south Florida. Under conditions which reflect actual rainfall over the past 20 years, the proposed surface water management system would have discharged 19 out of 20 years into the Water Conservation Area (Loxahatchee Refuge). In some years this discharge would have continued for approximately three months. The unrebutted testimony of expert witnesses called by Respondent established that the entire 1,393 acre tract referred to herein as "the property" is a freshwater wetland habitat. The western half is emergent marsh land, while the eastern half is forested with woody species. The wetlands on the property form a valuable wildlife habitat. Environmentally, they are in excellent condition. This area has not been adversely affected by drainage, fire or exotic species. These marshes also have good habitat diversity. The populations of aquatic invertebrates and forage fishes that are produced in these Everglades marshes are utilized by the many species of wading birds that feed in these wetlands. The proposed project will adversely affect wildlife species, including a variety of wading birds which will likely be unable to relocate. While this is undesirable from an environmental standpoint, conversion of this land would provide benefits from an agricultural standpoint, and would create additional water recreational facilities.
Recommendation From the foregoing, it is RECOMMENDED: That Respondent enter a final order denying the application. DONE and ORDERED this 30th day of November, 1983, in Tallahassee, Florida. R. T.
