Thanks, Kyle Steven W. Gong Senior Ecologist/Water Resources Planner Education Ph.D.(Studies),Zoology,University of Florida M.S.,Zoology, University of Florida B.A.,Biological Sciences,University of Delaware Relevant Experience Steve Gong has 35 years of experience in planning and execution of multidisciplinary studies focused on problem definition, development of alternative solutions, and management decision support for clients from both the private and public sectors. His practice areas focus on water resources and water supply planning, ecosystem management and restoration, and regulatory compliance with groundwater, surface water,and wetland protection guidelines. His experience spans issues related to agricultural and urban stormwater runoff, and both domestic and industrial wastewater treatment system discharges to surface and groundwater. Representative Projects • Project Manager and Lead Water Quality Scientist.Agricultural and Urban Stormwater Monitoring and Management Planning, Four Drainage Districts in the Everglades Agricultural Area South of Lake Okeechobee. Mr. Gong designed, implemented, and managed an 8-year program that involved maintaining Special 298 Drainage/Water Control District compliance with specific conditions contained within NPDES permits regulating stormwater discharges from agricultural and urban lands near Pahokee, Belle Glade,South Bay,and Clewiston to Lake Okeechobee.The program included permitting negotiations with the Florida Department of Environmental Protection, surface water quality and quantity monitoring studies, biological monitoring in Lake Okeechobee at inflow sites, flood-control pump station calibration, and phosphorus control strategy evaluations. The project included management of several analytical laboratories. • Task Manager. Water Quality Monitoring of S-332D Stormwater Detention Area Operational Effects on Everglades National Park(ENP), U.S. Army Corps of Engineers,Jacksonville District. Mr. Gong was project task leader responsible for developing and implementing a surface water, groundwater, and wetland biological monitoring program to assess the effects of placing the 810- acre S-332D Stormwater Detention Area on line. The primary emphasis was on assessing the potential for groundwater recharge and contaminant transport into ENP. The monitoring program included installation of groundwater monitoring wells,and environmental monitoring(groundwater, surface water,sediment,and ecological)around the perimeter of the S-332D Detention Area,as well as along two transects along the eastern margin of ENP just west of the Frog Pond Area in the C-111 Basin.The project included management of a subconsultant analytical laboratory. • Project Manager. Design/Build/Operate (DBO) Aquatics Pilot Program for Phosphorus Reduction in Urban Stormwater, Village of Wellington, Florida. Mr. Gong managed a 2-year wetland treatment technology demonstration focused on reducing total phosphorus concentrations in the Village's Basin B stormwater. Excess surface waters from Basin B historically were discharged to the Loxahatchee National Wildlife Refuge (Water Conservation Area 1). The Village was in search of technologies which could reduce stormwater phosphorus levels to comply with the Everglades Protection Area standard of 10 ppb. The team Mr. Gong managed designed, constructed, and operated a 2-acre facility consisting of seven earthen impoundments established with different types of wetland vegetation and plumbed "in series". Mr. Gong facilitated interagency communications, CH2MHILL GONG RESUME_20130919 1 STEVEN W. GONG and technology linkage with similar investigations of floating, emergent, submerged aquatic vegetation, and periphyton based treatment wetland systems under study elsewhere in South Florida.The project included management of a subconsultant analytical laboratory. • Project Manager. Periphyton-Based Stormwater Treatment Areas (PSTAs) for Phosphorus Reduction in Stormwater,South Florida Water Management District. Project manager for a 5-year technology demonstration study supporting Everglades Restoration in South Florida. The studies included PSTA development in tank mesocosms, half-acre test cells, and four 5-acre pilot scale wetlands. Phosphorus treatment performance was monitored under varied hydraulic/phosphorus loading rates and residence times. Effects of system depth,substrate, and other design factors were also assessed. Mr. Gong facilitated interagency review meetings (FDEP, USACE, DOl-ENP, EPA, and agricultural interests), and provided quality control oversight for all project reports. This project included management of a large group of subconsultants and several analytical laboratories. • Project Manager. Section 24 Wetland Park Feasibility Study, Master Plan Development and Implementation, Village of Wellington. Mr. Gong managed this multidisciplinary planning and environmental design project focused on converting approximately 400 acres of former agricultural lands into a wetland park/stormwater detention system. The Village's vision was to use the system for multiple purposes including stormwater detention,ecosystem restoration,and passive recreation by residents and visitors to the Village. Mr. Gong led development of conceptual designs for the wetlands and the recreational facilities. He facilitated an interagency review meeting, and was responsible for final report preparation. Subsequent phases of work included conceptual design of an Environmental Education and Conference Center applying Leadership in Energy and Environmental Design(LEED)concepts endorsed by the U.S.Green Building Council. • Task Manager/Lead Ecologist. Aquifer Storage & Recovery Technology Demonstration Project, South Florida Water Management District. Mr. Gong served as task manager for the ASR system initial conceptual design activities for the District's first 50-mgd raw water ASR well system designed to divert excess surface waters to an underground storage zone in the middle and upper Floridan aquifer, for subsequent retrieval to meet water supply demands during drought conditions. He introduced the concept of use of constructed wetlands for solids reduction in the source waters prior to injection underground, and also for water quality polishing after water retrieval and prior to subsequent surface water discharge. • Task Manager and Lead Marine Ecologist. Receiving Water Studies to Assess the Effects of Reverse Osmosis WTP Concentrate Discharges on Salt Creek, Gasparilla Island Water Association (GIWA). Mr. Gong was lead scientist for design of monitoring studies addressing RO brine toxicity and effects of surface water discharge of concentrate discharge on estuarine biological communities. On behalf of GIWA, Mr. Gong assisted with management of discharge impact issues raised by regulatory agencies as an element of the NPDES permit renewal for this RO facility's surface discharge of concentrate. • Task Manager/Lead Marine Ecologist. Impact Assessments of Proposed Dredging Operations in Pine Island Sound and Matlacha Pass Aquatic Preserves, Lee County Electric Cooperative. Conducted field surveys of benthic invertebrate communities along an electrical transmission line corridor. Bathymetric conditions were documented,and seagrass and shellfish community presence and composition were assessed. A brief technical report was prepared summarizing the field data, and providing recommendations for construction methods to minimize unavoidable construction-related impacts.

As requested,please find attached additional information on project staffing and our qualifications for this work. Please don't hesitate to contact me if you have any questions or need additional information. We look forward to working with you and the county on this project. Sincerely, CH2M HILL /14/ 60,61101/ William D. Beddow,PE Vice President CH2MHILL's Watershed and Water Quality Related Assessment Capabilities CH2M HILL offers comprehensive services in assessing,designing and implementing innovative strategies for watershed assessment and water quality compliance. We have extensive experience with water quality standards and have assisted a variety of clients and organizations in the development of cost-effective approaches to address existing water quality issues, pending regulations, and associated effluent limits. Our key services include: • Water Quality Monitoring(Discharge and receiving water) • Watershed Assessments and Planning • Water Quality Standards • Total Maximum Daily Loads (TMDL) • NPDES Permit Compliance • MS4 Compliance • Integrated Municipal Stormwater and Wastewater Planning • Green Infrastructure/Low Impact Design • Water Quality Credit Trading • Use Attainability Analyses/Site Specific Limit Investigations • Economic Impact Analyses • Lake and Reservoir Modeling • Stream, River, and Estuarine Hydrodynamic and Water Quality Modeling • Mixing Zone Modeling • Stormwater and Collection System Modeling • Watershed Related GIS Capabilities The diversity of existing water quality issues and pending regulatory requirements has made compliance with water quality criteria very challenging for industries, local governments, and utilities. Requirements for meeting total maximum daily loads (TMDLs)for impaired waterbodies,and changes in standards or criteria for nutrient, mineral, and related parameters,are causing wastewater and stormwater permittees to evaluate potentially costly improvements to their facilities. CH2M HILL's approach for addressing these issues is to focus on a comprehensive evaluation of conditions and management alternatives to meet changing regulatory requirements. Analysis of water quality can provide insight into the existing conditions of a waterbody and is commonly used by States to determine whether the designated uses of a waterbody are being met. CH2M HILL has extensive experience in collecting and interpreting water quality data.An in-depth understanding of water quality standards is required to assess conditions and to determine what point and non-point management strategies meet specific goals.Watershed and receiving water quality modeling is often needed to predict how effective management strategies will be in meeting water quality targets. CH2M HILL's Watershed and Water Quality Management core technology supports our client projects and initiatives to respond to multiple driving regulations,which include:the Clean Water Act (CWA)and the National Pollutant Discharge Elimination System (NPDES) permitting program,state watershed 1 management regulations, Numeric Nutrient Criteria (NNC), and TMDLs. CH2M HILL's watershed and water quality technologists assist our clients in developing strategies and executing projects to maximize the value of their watershed protection investments to enable them to achieve multiple environmental benefits for their dollars spent. Watershed and Water Quality Assessment and Management provides a broad group of services that characterize and assess watersheds and develop protection and restoration strategies based on monitoring programs, hydrologic, hydraulic,and watershed pollutant modeling,stream assessment, public outreach and policy development, permit compliance, nutrient management strategies,and water quality trading.This breadth of knowledge is critical in watershed management planning to understand and account for the full range of impacts and interactions of recommended solutions. Our engineers and scientists can select potential watershed-based solutions that are cost-effective and provide ancillary environmental benefits. Using a multidisciplinary team of engineers,scientists, economists, and planners,CH2M HILL develops innovative alternatives such as watershed based permitting,water quality credit trading, use attainability analyses (UAA), and site specific limits. In many cases,watershed and/or water quality modeling is a core component in assessing the efficacy of alternative management strategies in reducing pollutant loadings from the watershed and to determine the impact on receiving water quality as a result of changes in point and nonpoint source pollutant loadings.The type of modeling that is performed depends on the questions that need to be answered,the type of system,and the pollutant of concern. CH2M HILL has significant expertise in the wide range of industry standard models,from simple spreadsheet based approaches to complex, dynamic multidimensional models. In conducting ambient condition assessments as well as developing appropriate regulatory strategies and watershed management alternatives,we combine the talents of local staff conversant with parochial issues with globally-based subject matter experts who have decades of experience in delivering implementable solutions to water quality-based problems faced by local governments as well as the private sector. We are expert at finding ways to cost-effectively achieve compliance with state and federal water quality standards. In our history of delivering projects around the globe,we have seen that taking social,economic, and environmental elements into consideration throughout the project life cycle can deliver strong business value,while strengthening an organization's relationship with customers,employees, and the community.We invite you to tap into our local as well as global staff resources as you manage your water quality-based issues for watersheds and receiving waters under your jurisdiction. Relevant Examples of Experience in Water Quality-Based Issues Management In Florida, CH2M HILL has provided water quality-based issues management support services requiring a blend of engineering and scientific expertise to governmental as well as private sector clients for many decades. Relevant experience includes developing and conducting storm-event based discharge monitoring programs in support of the Stormwater NPDES Permit for the City of Miami, and similar rainfall-driven monitoring of stormwater pumping into Lake Okeechobee from various lakeside surface water management"298"taxing districts. In support of private sector permittee interests with NPDES discharge limitations, we are currently conducting surface water monitoring of discharges into the Suwanee River and Lake Parker addressing metal translator issues focused on demonstrating compliance with copper water quality standards for ambient surface waters. On behalf of Tohopekaliga 2 Water Authority(TWA),we remain responsible for a decades-long ambient water quality as well as biological monitoring program assessing effects of discharges into receiving wetlands and surface waters. CH2M HILL has been the NPDES consultant for the Ports of Tampa,Canaveral and Miami since the inception of each port's NPDES program. Our collaborative efforts with our clients are important in preventing any potential for administrative penalties associated with non-compliance. For all of these water quality monitoring programs on behalf of our clients,we rigidly adhere to Standard Operating Procedures (SOPs) and Quality Assurance Plans required by the Florida Department of Environmental Protection. These SOPs address in situ data collection, including appropriate field meter calibration, as well as appropriate chain of custody records documentation and coordination of laboratory analyses with NELAP certified subconsultant firms. We have an established network of working relationships with appropriately certified analytical laboratories in the State addressing chemical analysis of water,sediments, and biological tissues,as needed to support particular environmental monitoring program scope elements. It is important to note that the value added by CH2M HILL engineers and scientists is our focus not lust on proper sampling, analysis, and documentation steps needed to protect data integrity, but on the ultimate disposition and application of the data produced by water quality monitoring programs. The above examples of historical or ongoing water quality monitoring programs are driven by regulatory issues associated with NPDES permit compliance,and evaluation of regulatory strategies for meeting NNCs and/or specific TMDL targets established in Basin Management Action Plans (BMAPs) here in Florida. Our nationally-recognized subject matter experts have been responsible for similarly strategic and regulatory-based programs across the country, representative examples of which include the following: • In support of the Everglades Restoration Program,CH2M HILL conducted a research and demonstration study of Periphyton-based Stormwater Treatment Areas(PSTAs)as a phosphorus reduction treatment technology. The work was performed for South Florida Water Management District as an element of its efforts to identify appropriate watershed-level treatment strategies for achieving compliance with water-quality based ecosystem restoration criteria. We worked closely with the District,the FDEP, and representatives of the Department of Interior/Everglades National Park in designing and implementing the monitoring and assessment program on which treatment technology performance was evaluated over a 5-year testing period. • As part of the NPDES requirements for both wastewater and stormwater permits, Forsyth County(Georgia)was required to conduct various watershed and stormwater management activities, including development and implementation of an environmental monitoring plan. The plan was designed to characterize ambient conditions, identify and investigate water quality impairments and improvement strategies,address requirements for 303(d)stream segments, and monitor the effectiveness of watershed management activities over time.The program included long-term monitoring of a traditional suite of ambient water quality parameters under both wet and dry weather conditions,short-term discharge effects focused on bacteriological 3 discharge effects,dry weather outfall screening, and biological conditions assessment. CH2M HILL has supported the County's water quality-based investigations since their inception in 2000. • In Utah,we are managing a 3 year research program monitoring 33 inflows to a large 45 sq mile wetland area on Great Salt Lake. We designed the program, and the USGS and the state div of water quality have implemented it. Information generated by this research program is to support development of watershed management strategies for improving habitat quality for the millions of shorebirds and waterfowl utilizing this lake as critical foraging habitat. • For a very high-profile Superfund clean-up site,we conducted the Gowanus Canal Remedial Investigation/Feasibility Study in Brooklyn, New York. Field studies designed to confirm site conditions and support remedial action planning included ambient surface water,soil/sediment, and groundwater monitoring along the canal,and specifically addressed tidal influences. Combined sewer overflow evaluations included considerations of both dry and wet weather discharge contributions to the canal. Parameters of concern included metals, PCBs, PAHs,and other pollutants which had accumulated in this highly urbanized canal contaminated by a variety of anthropogenic sources. These selected project examples document our firm's diverse expertise in both developing as well as conducting rigorous water quality monitoring programs designed to meet a broad range of client needs associated with ambient water quality conditions assessment. CH2M HILL Florida-based as well as national subject matter experts are available to support water quality monitoring project planning and implementation, as well as documentation of the effects of watershed or site management actions designed to improve water quality conditions leading to environmental system integrity and surface water use attainment.

Responsibilities included field platform maintenance,well sampling, logistics planning,water quality sampling and quality control review,vegetation and wildlife data collection,office data base input and quality control review, analysis, and report preparation. Mr. Gorsira managed a mixing zone evaluation for an industrial discharge to the Alafia River,Tampa Bay, Florida. Cargill Fertilizer's permit contained an allowance for five metals and proposed operational changes required the development of a new mixing zone model and the collection of new ambient river and effluent data. Mr. Gorsira developed a sampling plan for approval by Florida Department of Environmental Protection using trace metal sampling techniques (EPA Method 1669)during several tidal cycles. As project manager, Mr. Gorsira assisted Florida Power Corporation with data collection for a stormwater NPDES program at four power plant sites in Florida. Outfalls and drainage basins were identified during field inspections of each power plant. A stormwater sampling handbook was provided to the client to provide guidance on sampling methodology and collection of other data for completing permit forms. Mr. Gorsira is currently managing monitoring of wetland habitat to assess the impact of water withdrawals of two well fields for Bonita Springs Utility, Lee County, Florida as part of a Consumptive Use Permit. He is leads bi-annual assessment of vegetation and hydrologic response to operation of the wells located in the Tamiami aquifer. Uniform Mitigation Assessment Method (UMAM) assessments are performed on a bi-annual basis to determine the effects of well field operation during the dry and wet season. He successfully negotiated with the South Florida Water Management District (SFWMD)to reduce monitoring requirements resulting in significant cost savings to the client. Mr.Gorsira served as field program manager for a multi-year 301(h)waiver study for the Carolina, Bayamon/Puerto Nuevo,Aguadilla,Arecibo,and Ponce WWTPs in Puerto Rico.This large, complex program involved sampling of influent and effluent streams of the WWTPs, benthic populations and sediments, receiving water,fish communities,and documentation of coral communities. He directed monthly and quarterly sampling activities, coordinated sampling vessels, laboratory analysis,and provided oversight of daily tasks to scientific crew. Deployed acoustic doppler current profiler(ADCP) and retrieved data at the end of the deployment period.As part of this program, Mr. Gorsira participated in multiple research cruises onboard the OSV Anderson with the Environmental Protection Agency(EPA)and National Oceanic and Atmospheric Administration (NOAA)to demonstrate innovative plume tracking technologies developed by Mr. Gorsira to reduce analytical cost to the overall program. Mr. Gorsira managed an industrial discharge compliance project for the Cargill Fertilizer Bartow Facility in Polk County, Florida. He supported a detailed evaluation of conductivity levels in the discharge as part of operational changes associated with closure of the gypsum stack at the facility and excessive rainfall events. Mr. Gorsira successfully negotiated a compliance agreement with the Florida Department of Environmental Protection. As project manager, Mr. Gorsira directed a water quality study and mixing zone evaluation of a once- through cooling water discharge at the C.D. McIntosh and Larsen Memorial Power Plants to determine 6 the source of elevated copper concentrations within Lake Parker, Polk County, Florida. CH2M HILL conducted a mixing zone analysis that demonstrated that the available dilution in Lake Parker was sufficient to qualify for a mixing zone. Mr. Gorsira employed ultra-clean field sampling techniques (EPA 1669 Method)to characterize influent,effluent,and ambient lake conditions. Mr. Gorsira has provided assistance with field activities to implement a one-year water quality and quantity monitoring program to develop a water and nutrient budget for Lake Panasoffkee in Sumter County, Florida.This study,funded by the Southwest Florida Water Management District Surface Water Improvement and Management(SWIM) program, determined the status of water quality,source of nutrients,extent of loadings,the contribution of groundwater, and characterized pollutant loads from stormwater runoff and septic tank leachate. Mr. Gorsira was responsible for compliance monitoring for the Hillsborough County Aviation Authority after the construction of Airside"F" at Tampa International Airport.The monitoring involved collection of storm event and base flow water quality samples prior to discharge to waters of the state.The data was compiled and presented in a technical memorandum to the Aviation Authority for submittal to the regulatory agencies. Mr. Gorsira assisted the City of West Palm Beach in a feasibility analysis on routing surface drainage through a 640-acre parcel as part of the Water Catchment Area (WCA),the City's water supply. Mapping of wetland and upland communities,exotic species cover,determination of wetland hydroperiods, and assessment of protected plant and animal species were conducted to evaluate potential impacts of the proposed project on biological resources in the WCA.This information will be used to develop a framework and criteria for evaluating similar systems for incorporation into the WCA. Mr. Gorsira coordinated and obtained a renewal of a NPDES permit for the emergency discharge of brine wastes of a reverse osmosis plant in Englewood, Florida. Historical data review and performance data were critical components to obtain specific waivers established by the permitting agencies for issuance of the permit. Mr. Gorsira served as team leader for a long term field sampling program for the RCRA and CERCLA investigations at numerous sites located in Vieques, Puerto Rico.These investigations included sampling of surface and subsurface soils,sediments,groundwater, and surface water systems, in addition to estuarine lagoons.These tasks included management of numerous subcontractors,suppliers,and laboratories. Liaison with regulators from EPA Region II and Puerto Rico EQB, including involvement of the public,were required at all levels to maintain effective communication among all team members. The program successfully passed an EPA audit during sample collection of all media.Close coordination was required with subcontractors to avoid unexploded ordinance (UXO)and strict sampling protocols were developed and adhered to in order to collect samples at the sites on the East and West side of the island. Mr. Gorsira assisted with U. S. Coast Guard(USCG)Aid to Navigation (ATON) Battery risk evaluation project conducted in Tampa Bay, Florida. He assisted with prototype investigations of sediments at multiple locations within the bay which resulted in a national strategy for the USCG to address the battery disposal issue. Mercury was the major contaminant of concern and the sampling results of sediment,water and biota were used to build a model of the various systems to evaluate potential risk from mercury.The Coast Guard was under national scrutiny and involved review of each step by a science advisory board which included regulators and academicians specializing in mercury. 7 Mr. Gorsira was field team leader for a 2-year Water Quality Based Effluent Limitations (WQBEL)study on behalf of Tropicana Products.This study was conducted as an element of industrial operations/NPDES permit renewal under the requirements of Chapter 62-620, FAC.The study included collection of wet and dry season ambient water quality and assessment of sediments and seagrass cover in the Braden River, Manatee County, FL,deployment and retrieval of S4 current velocity meters for the performance of mixing zone modeling. Mr. Gorsira was lead scientist to determine the extent of possible metals contamination in sediment and lake water at Dock 45, Fort Davis located on Lake Gatun, Panama. Lake Gatun is part of the Panama Canal and serves as a potable water supply.The objective of the investigation was to determine the extent of potential contamination and to perform a screening level risk assessment. Surface water and sediment sampling were performed by Mr. Gorsira at grid-specific locations near the dock and at background stations in the lake.This project also involved the preparation of a site-specific health and safety plan (HSP). Mr.Gorsira was a field team leader on studies of receiving water quality issues of the Gasparilla Island Water Association (GIWA)Water Treatment Plant effluent (reverse osmosis brine concentrate)to aquatic organisms. Mr. Gorsira performed sample collection of surface water and sediments to evaluate the relative effects of RO brine discharge on estuarine receiving waters. He participated in meetings with the Florida Department of Environmental Protection (FDEP) regarding resolution of permitting issues. Mr. Gorsira has been involved with the Lake Maggiore Environmental Assessment program in St. Petersburg, Florida as a project coordinator of field activities. His responsibilities included the coordination and implementation of the monthly water quality sampling,storm event sampling,and vegetation transition zone determinations.

H.aMab Stanley Hole Mau..ce L Plummet Nathan.,t Reed J Ned Gallagher John L.Hundly Naples Feet Myr., Nob.Sound ST.Cloud PahokN Formerly Central and Southern Florida Flood Control District {— -- Natural Resources The major negative impact associated with the proposed topographical alterations will be the permanent elimination of 128 acres of low lying bracki wetland which principally supports healthy mangrove forest and its associated biota. In addition, demucking and filling of this area could adversely impact the red mangroves lining the banks of the several creeks which are to be retai As proposed, the Pelican Bay project will make considerable utilization c the upland pine flatwoods and rosemary-dwarf live oak habitat of the site, whi appears well suited for development. In addition, the applicant has proposed preserve approximately 76 acres of bay tree stands and to place in a reserved category approximately 570 acres of estuarine area which includes the Clam Bad and the surrounding areas of mangroves. However, the applicant has also prop( to fill , for development purposes, 128 acres, including 109 acres of mangrove! at the north end of the saline wetland area around Upper Clam Bay which can be • expected to result in a reduction in this area's contribution to the detritus based food chain. These 128 acres represent approximately 45`" of the wetland! the site. Due to the nature of the upland areas of the site, the impact of develops in these areas on the wildlife of the region is expected to be minimal . Cons' tion of the proposed surface water management system will also provide habita for an increased number of freshwater vertebrates and invertebrates. However the proposed filling of the 128 acres of wetland habitat in the Upper Clam Ba; area can be expected to reduce the roosting and feeding areas available for ti wading birds of the region, including the eight threatened or endangered bird species which now utilize the property. In particular, a reduction can be ex; in both the population of the small fish important to the food chain in suppo the wading birds and in the population of the larger fish and crustacea found the bay. • Public Facilities Wastewater Treatment and Disposal. In view of the proximity of the Coll County District "A" regional wastewater treatment facility and the restrictio • placed on the cons., uction of new sewage treatment plants by DER, it is recom that the applicant strongly consider connection to the regional facility. Sh • this not be feasible, then consideration should also be given to an alternati means of on-site disposal , other than the proposed deep well injection system Storm Water Disposal . Due to the location of this project, no public st water disposal facilities will be affected. Water Supply. Water supply impacts are sunrrarized under the Water Quant section. In reviewing the natural resource and water related aspects of the Appli cation for Development Appr;,val for the prc,nosed ;'elican Eay di.:,2;ophent, the District has determined that the following. major issues of adverse impact require resolution: (1) The capability of the Floridan aquifer to meet the potable demands of the proposed development on a long term basis, and without adversely impacting any other water supplies in the area, both qualitatively and quantitatively, has not yet been documented. (2) The existence of a disposal zone in this area for the proposed deep well injection of waste brine and sewage effluent has not yet been documented. (3) The proposed filling of 128 acres of saline wetlands, or approximately 45" of the wetlands on the site, will adversely impact 109 acres of mangrove community and will result in a reduction of valuable habitat for rare and endangered species which utilize the site. In addition, we note the following: (1) The applicant should amend the drainage plan to include a slight perimeter berm on all lakes receiving runoff from the golf course and a 7:1 rather than the proposed 4:1 slope on all lakes. (2) Until such time as the tidal surge 100 year flood elevations are established, minimum building floor elevations should be 10 feet above mean sea level. (3) Minimum lake control elevations should be 4 feet above mean sea level for the first phase, with approval of elevations for subsequent phases or adjustments to first phase elevations withheld pending demonstra- tion, at the time of permit review, of satisfactory surface-groundwater relationships. (4) The applicant should revise projected average and maximum daily potable water demands to more accurately reflect the historical records and trends in the area and the type of community planned. (5) Effective with the change in water management district boundaries scheduled for December 31, 1976, a Surface Water Management Permit for the project's drainage system and a Water Use Permit for the proposed withdrawals for potable use will be required, pursuant to Chapter 373, Florida Statutes. Should the proposed withdrawals from the project ► lake system for irrigation purposes exceed three million gallons during a maximum month, they will also require a Water Use Permit. -19-
