[Adoption Hearing] Applicant: Collier County n. LOCATION: This petition does not pertain to a specific property. In. BACKGROUND and PROJECT DESCRIPTION: This is the Adoption review of that portion of the Growth Management Plan Amendment petition CPSP-20 I 0-2 that was previously reviewed by the EAC at Transmittal. The petition is part of the 2009-2010 combined cycles of GMP amendments, including one 2008 cycle petition. The petition seeks to amend the Wellfields Map based upon the most recent hydrologic modeling report prepared in 2010. Transmittal hearings on this amendment were held on December 1,2010 (EAC), December 16, 20 I 0 and January 20, 20 II (CCPC, Collier County Planning Commission), and on March 22, 2011 (BCC, Board of County Commissioners). The respective Transmittal recommendations/actions are presented below. Included in the EAC binder for this petition are the following documents: (a) existing Wellhead Protection Areas Map; (b) EAC staff report from the Transmittal hearing, which provides more explanation and staff analysis; ( c) Hydrologic Modeling Report; (d) Ordinance with Exhibit A, the proposed Wellhead Protection Areas Map. Transmittal Recommendations: STAFF: Transmit to DCA. EAC: Transmit to DCA (vote: 3-0). CCPC: Transmit to DCA (vote: 9/0), with requirement that the City of Marco Island - Marco Lakes water reservoir be added to the map (located in the northeast quadrant of US-41 East! Collier Boulevard intersection). BCC ACTION: Transmit to DCA (vote: 5/0), per CCPC recommendation. Florida Department of Community Affairs ORC Report: After review of Transmitted GMP amendments, the Florida Department of Community Affairs (DCA) renders an Objections, Recommendations and Comments (ORC) Report. Only Objections can form the basis of a non-compliance determination, unless the adopted amendments vary significantly from those transmitted. If an Objection is not adequately addressed when adopted, then the DCA may (presumably will) find the amendment to be "Not Item VIII.A. in Compliance" with Florida Statutes, and issue a Notice ofIntent (NOr) to indicate such noncompliance. In its June 3, 2011 ORC Report for the 2009-2010 combined cycles of GMP amendments, DCA offered no Obiections. Recommendations or Comments relevant to petition CPSP-20 1 0-2 presented for EAC review. Additionally, all other state and regional review agencies offered no comments/objections relevant to this petition.

ENVIRONMENTAL ADVISORY COUNCIL STAFF REPORT MEETING OF December 1.2010 I. NAME OF PETITIONERlPROJECT: Petition No.: Petition Name: CPSP-2010-2 Various Amendments to the Future Land Use Element and Maps in the GMP - Wellhead Protection Areas and Proposed Wellfields and ASRs Map ONLY (Comprehensive Plan Map Amendment initiated by the Collier County Pollution Control and Prevention Department) [Transmittal hearing] Collier County Applicant: II. LOCATION: This petition does not pertain to a specific property. III. BACKGROUND and PROJECT DESCRIPTION: In the Collier County Growth Management Plan (GMP), Objective I of the Natural Groundwater Aquifer Recharge Sub-Element (NGW AR) and subsequent policies, and Objective 3.3 of the Conservation and Coastal Management Element (CCME) and subsequent policies, requires the County to maintain maps of potable water wellfields that are most sensitive to contamination from nearby development activities and other activities and conditions. Every two years, the County is to revise and update its three-dimensional computer models, based upon a variety of data, and revise wellfield maps, as necessary. In the GMP, there is a single map in the Future Land Use Element known as the Wellhead Protection Areas and Proposed Well fields and ASRs Map that is part of the Future Land Use Map series. Section 3.06.00 of the Land Development Code (LDC) contains "wellfield risk management special treatment overlay zone maps," maps that are similar to, but with greater detail than, the map in the Future Land Use Element. Similar to the GMP, the LDC requires review of the wellfield maps, but on an annual basis. The biennial process in the GMP consists of updating the computer model, then, if warranted, revising the map in the Future Land Use Element. Subsequently, any affected map(s) in the LDC would need to be amended. Since the LDC includes regulatory provisions, it is important to amend the LDC map(s) as soon as possible after the GMP map has been amended. EAC Meeting 12/1/10 The attached 33-page report provides the technical basis for the proposed map amendment; a similar report was used to support such map amendments in 2007, and in other prior years. The proposed Wellfields map itself is located on page 6; the summary of map changes (affected well fields) is identified on pages 4 and 5. Also, attached is the existing Wellfields map. The proposed amendment is technical in nature and is based upon the sound science of the computer modeling; it has no impact upon public infrastructure or surrounding properties (though properties newly added to a protection zone would be subject to additional regulatory scrutiny). Consideration of this proposed amendment at this EAC meeting was duly advertised in the Naples Daily News as required by CCME Policy 3.3.2. IV. GROWTH MANAGEMENT PLAN CONSISTENCY: This is a proposed amendment to the Future Land Use Map series. It is required to be periodically revised, as necessary, pursuant to Objective 1 of the NGWAR and subsequent policies, and Objective 3.3 of the CCME and subsequent policies. V. RECOMMENDATION: That the EAC recommend approval of petition CPSP-2010-2, proposed amendment to the Wellhead Protection Areas and Proposed Well fields and ASRs Map.

PROPOSED FUTURE LAND USE MAP IN THE GROWTH MANAGEMENT PLAN...... 6 GMPpaper 2010 - Wellfield Protection Report V511-15-10.docx Paper Page 2 of 33 Growth Management Plan SUMMARY The Collier County Pollution Control and Prevention Department (PCD) is responsible for protecting the potable groundwater resources of Collier County under the Land Development Code (LDC) Section 3.06.00, titled "Groundwater Protection." This Section of the LDC relates to public water supply wellfields permitted to withdraw a minimum of 100,000 gallons per day of groundwater from the topmost "surficial" and next lower "intermediate" freshwater aquifer systems ofthe county. In addition, the PCD is responsible under Section 9J-5.006 of the Florida Administrative Code (F AC), relating to the Future Land Use Element of the Growth Management Plan, to update and make input to the county's future land use maps when appropriate. A recent review and modeling of the municipal water supply wellfields within Collier County indicated that the existing 2007 approved "Collier County Wellhead Protection Areas, Proposed Wellfields, and Aquifer Storage and Recovery Wells (ASR's) Map" (Map) requires updating. This proposed amendment to the 2007 version will update the Map so it reflects more closely what presently exists in Collier County. In summary, there are eight major municipal well fields currently falling under LDC Section 3.06.00. Due to recent modifications, either to the number of wells in a field or to the permitted well pumpage rates, very minor changes are required to the computer generated shapes of the wellfield protection zones for all eight wellfields. The latest shapes of these wellfield risk management special treatment protection zones are shown on Map 1. In addition the installation three new shallow water supply wells at Port of the Islands, has resulted in this wellfield being added to the Map. Map 1 also shows the currently approved potential future wellfield areas and the permitted ASR wells within the county, as required by FAC Section 9J-5.006. The purpose of this Paper is to present and describe the current conditions found within the proposed Future Land Use Map as pertaining to freshwater wellfields and ASR's, and to request the appropriate committees and bodies accept and approve inclusion of the revisions into the future Land Use Map for use in the Growth Management Plan for Collier County. GMPpaper 2010 - Wellfield Protection Report V5 ll-15-JO.docx Paper Page 3 of 33 Growth Management Plan 1. AMENDMENT REQUEST The PCD is pursuing an amendment to the "Collier County Wellhead Protection Areas, Proposed Well fields, and Aquifer Storage and Recovery Wells (ASR's) Map" (Map) located within the Collier County Growth Management Plan's Future Land Use Element. This proposed amendment will update this Map so it more closely reflects what presently exists in Collier County. Through this process the public will be informed by Public Notices, and will have an opportunity to share their opinions and thoughts during public hearings held by the Collier County Environmental Advisory Council (EAC), the Collier County Planning Commission (CCPC) and, finally, the Collier County Board of County Commissioners (BCC), where the proposed amendment will be considered for adoption. If this amendment is approved, it will then be forwarded to the Florida Department of Community Affairs (DCA) for their review to determine compliance with Florida Statutes. Following this process the PCD will then pursue the amendment of Collier County's LDC Section 3.06.00 "Groundwater Protection" to ensure the outdated well field risk management special treatment overlay zones are revised to reflect what presently exists. The purpose and intent of LDC Section 3.06.00 is to protect future and existing public water supply wellfields, protect natural aquifer system recharge areas, protect countywide ground water resources, and protect the public and resources from potential pollutant point sources. This regulation requires that the public water supply wellfields within the county are protected by means of "wellfield risk management special treatment overlay zones" commonly known as Well field Protection Zones. These zones are derived from a three-dimensional computer-modeled analysis of ground water and solute transport in the county's freshwater aquifer system. This modeling has been done by the PCD since 1989. Following the initial setup of the model by a consultant in 1989, the model was run in 1991, 2003, 2004, 2007 and, most recently, in 2010. Each run of the model produced changes to the previous run results because of the input of new data and revised, increasingly stringent, wellfield permit conditions imposed by the South Florida Water Management District (SFWMD) (i.e., wellfield changes that occurred since the previous run of the model). The proposed map, "Map 1," reflects the results of the 2010 modeling. The reference statutory Geographic Information System (GIS) map of the Wellfield Protection Zones for each wellfield resides in the county's GIS map library. Shown below is a summary of the historic wellfield updates and hence modeling changes between 2004,2007, and 2010.

Some of the shape changes, especially in large wellfields with many wells, are essentially very minor - and this is the case for the Immokalee, Everglades City, Collier County (Golden Gate), City of Naples (Coastal Ridge) and City of Naples (East Golden Gate) wellfields. However, for the small Ave Maria, Orangetree, and FGUA (Golden Gate) wellfields, the changed permitted pumping rates applied in the 2010 model have, in each case, resulted in a noticeable change to the Well field Protection Zone shapes. Map 1 presents and the PCD requests adoption of the actual results of the 2010 modeling - whether the Wellfield Protection Zone shape change was small or large. As required by Section 9J-5.006 of the FAC relating to the Future Land Use Element of the Growth Management Plan, also shown in Map 1 are the locations of approved potential future wellfield areas, planned surficial aquifer supply wells, and the SFWMD-permitted ASR wells in the county. The potential future wellfield areas and the planned surficial aquifer supply wells shown on Map 1 are extracted from Figure 5-Iofthe la-Year Water Supply Work Plan. The original approval of this potential future wellfield area resulted when the BCC approved a comprehensive plan amendment to adopt the la-Year Water Supply Work Plan on February 24, 2009, by Ordinance No. 09-04 (DCA 09-RWSPI). The ASR's shown on Map I are those documented as having received SFWMD ASR Permits within the county. The Map shows four sites at which ASR well permits have been issued to county wellfield stakeholders: Marco Island (9 Wells), City of Naples (4 Wells), Manatee Road (1 Well), and Livingston Road (1 Irrigation Quality Well). The Carica Road ASR shown in the 2007 Map is withdrawn because following completion of a test well at the site no ASR was installed. The following Sections and Appendices provide supplementary details of the proposed and historic amendments, an explanation and intent of the model, the stakeholders who were contacted, and the wellfield data collected during this consultative process. The PCD requests the adoption of Map 1 as the Future Land Use Map relating to the wellfield protection areas, proposed surficial aquifer wells, and current ASR's for incorporation into the Growth Management Plan of Collier County.

Some of the concepts and opinions expressed at that time may not be valid now or may have been overtaken by events; they are provided to record the development of this modeling within the county. Chapter 163.3203, FS, mandates the adoption of Land Development Regulations that "..,provide for protection of potable water wellfields". The Collier County Growth Management Plan translates this mandate into a series of Goals, Objectives, and Policies for implementation of ground water quality protection in Collier County. The goals state that the County shall: (1) identify and protect natural ground water aquifer recharge areas from activities that could degrade and/or contaminate the quality of ground water; (2) protect natural ground water aquifer recharge areas from activities that unacceptably alter the ground water recharge,' (3) protect the County's ground water resources to ensure the highest water quality practical; and (4) conserve, protect, and appropriately manage the County's fresh water resources. Objectives and Policies included in these goals are: (1) to develop and maintain a 3-dimensional computer ground water flow model for existing and planned wellfields,' (2) to amend the Comprehensive Plan to include modeled areas as "environmentally sensitive areas",' (3) to develop an ordinance to provide for an appropriate level of protection for all Collier County ground water,' (4) to develop an ordinance(s) that will address well construction, rock mining and excavation, blasting, and confining units; (5) to develop an-ordinance that will address both existing and future land use and surface activities relative to petroleum storage tanks, stormwater, regulated substances, industrial and domestic wastes,' (6) to develop a ground water protection ordinance to protect existing and future wellfields; and (7) to develop technical criteria for determining what areas are critical to the County's long-term ground water needs, e.g., Natural Aquifer Recharge areas. The citizens of Collier County derive their potable water largely from the Surficial Aquifer System via either the permitted public water supply wellfields or the private and household water wells. Water consumption from these sources are divided into three main use areas,' potable water, agricultural use, and recreational uses. The Surficial Aquifer System in Collier County is composed of the unconfined water table aquifer and the underlying, semi-confined Lower Tamiami Aquifer, both of which are recharged by direct infiltration of precipitation that accumulates on the surface. The water table of this aquifer system lies at or within a very few feet of the ground surface, being visible in such situations as canals, ponds and lakes, wetland areas, and wet retention stormwater areas. The unsaturated soil or rock above the water table is commonly only a few inches to a few feet thick and provides little attenuation of most contaminants or pollutants passing from the surface downward to the water table. Thus, the Surficial Aquifer System is very susceptible to contamination resulting from land use activities. The sedimentary rock units underlying Collier County represent several millions of years of mixed carbonate and siliciclastic marine shelf and coastal deposition under subtropical to tropical GMPpaper 2010 - Wellfield Protection Report V5 J J-J5-JO.docx Paper Page 7 of33 Growth Management Plan climatic conditions. These rock units exhibit generally unpredictable vertical and lateral microlithologic as well as permeability and porosity variations with some generally recognized laterally extensive zones of relatively low permeability separating other zones of relatively high permeability. These latter zones or aquifers contain producible water and are separated by zones of lower permeability, i.e., aquitards. Nearly all of the potable water in Collier County is obtained from two permeable zones of the Surficial Aquifer System. This System is unconfined and is recharged directly from the surface. Hence, accurate knowledge of ground water flow directions and recharge characteristics is extremely important when attempting to predict ground water movement. Potential ground water contaminants from land use activities are introduced into aquifer systems via moving water. This movement may be in vertical and/or lateral directions. The conventional wisdom is that with increasing distance traveled in heterogeneous soils/rocks, the more attenuated or "diluted" a pollutant will become. However, even extremely minute amounts of some contaminants have high toxicity levels. Natural attenuation processes include filtration, sorption, chemical processes, dilution, and microbiological decomposition. The thin, sandy soils of Collier County are less capable of providing extensive natural attenuation of many pollutants generated by land use activities as compared to thicker, more heterogeneous soils. Hence, contaminant- generating land use activities should be regulated in order to reduce the potential for introduction of pollutants into the ground water system. Potential ground water contaminants are as numerous and as varied as the land use activities that produce them. In addition, each contaminant (e.g., bacteria, dissolved solids, petroleum products, pesticides, fertilizers, septic or sewage waste) behaves differently in the water system in terms of its residence time, movement with other pore fluids, reactivity with or to pore fluids and soil/rock, and reactivity to/with other chemicals within the aquifer system. Because of the lack of a complete understanding of contaminant behavior in the aquifer system, combined with only a very general knowledge of local soil/rock characteristics affecting this behavior, it is difficult to predict with a high degree of certainty exactly how far or in what direction a particular contaminant will travel in a given time. Numerous studies have been conducted in attempts to estimate travel characteristics, travel times, and residence times of commonly introduced contaminants in aquifer systems. Because of the inhomogeneity of the soil/rock and aquifer systems, most of these estimates provide either ranges of values for velocity, distance, and residence time for the contaminants or present some minimum setback distances based on risk potential to human health and welfare. Hence, rate, distance and longevity of contaminant data for an aquifer system should be recognized as a range of values when considered in the light of risk analysis. In order to develop an effective ground water protection program, an effort must be made to establish a minimum County-wide water quality baseline applicable to all potable water wells and against which to compare suspected contaminated areas. In addition, areas around public water supply wellfields should be provided protection in the form of land use restrictions and prohibitions. The extent of such areas should be predicated on geologic and hydrogeologic data as well as knowledge of the behavior of contaminants in these systems. Wellfield protection zones are in reality risk management zones. Such zones must be based on the best available regional and local geologic and hydrogeologic information; historic and projected water demands; evaluation of contaminant behavior in the ground water systems; natural attenuation processes; remediation time and technology; and establishment of specific contaminant targets and thresholds. Computer models can evaluate data and generate projections of ground GMPpaper 2010 - Wellfield Protection Report V511-15-10.docx Paper Page 8 of33 Growth Management Plan water flow, contaminant travel, and drawdown characteristics within some confidence limits, but it still remains a policy decision of "how much risk is too much risk". The three-dimensional ground water flow model for wellfields employed as a predictor in this study was programmed with a 20-year planning horizon. Input such as that mentioned above was then used to define a 20-year risk management zone around each public water supply wellfield. All ground water within this zone has the potential to reach the wellhead within 20 years, and numerous pathways were modeled to illustrate this. Within this zone, three additional zones were established. Zone 1 is defined as that area closest to the wellhead which contains five percent of the total ground water within the 20-year planning zone that will generally reach the wellhead within one year. The rationale for this zone is one of sanitary hazard versus natural attenuation and risk limits for most contaminants related to sanitary systems. Zone 2 is defined as that area closest to the wellhead, but outside of Zone 1, that contains ten percent of the total ground water within the 20-year planning zone. The model indicates that water in this zone will generally reach the wellhead within 2 years. The establishment of zones 2 and 3 is predicated on travel times, natural attenuation, and remediation time concerns for contaminants in the regulated or hazardous products and wastes categories. Zone-3 is defined as that area within the 20-year planning horizon in which 25 percent of the ground water will reach the wellhead within approximately five years. Zone 4 is defined as the remainder of the 20-year planning zone and is the immediate Zone of Contributionfor these wellfields within the planning horizon time frame. Significant contamination of ground water has occurred in every state of this nation, and is being detected with increasing frequency in urban and rural areas; in industrial as well as in agricultural regions, and is adversely effecting development and quality of life in many regions of the world (e.g., Love Canal). In Collier County, the water table is generally within six feet of the surface and the main potable water aquifers are recharged from infiltration through thin soils and semi- consolidated rock units. Natural attenuation of contaminants is not as effective as in other areas where there are thick soil horizons and the where the water table lies deeper beneath the surface. In addition, development in Collier County exposes the water table directly to land use pollutants via quarries, landscaping, stormwater retention/detention systems, accidental/incidental surficial pollution and poorly constructed and maintained wells. The only long term approach to maintaining an acceptable level of ground water quality is to reduce the possibilities for ground water contamination rather than to depend on remediation. This approach must be based on the acquisition and analysis of accurate hydrologic and geologic data, understanding of the nature and reactions of contaminants in the ground water system, knowledge of background water quality levels, and realistic projections of future demands. From this data can be developed a comprehensive ground water protection program that addresses overall water quality across the County as well as that in the zones of contribution for public water supply wellfields. 2.2 MODELING OF 2003 The purpose of the 2003 modeling and reporting by the PCD's consultant, Dr. M.L. Voorhees, was to update the methodologies and results of the initial Collier County regional three-dimensional ground water flow model, and the subsequent wellfield submodel transport simulations performed by Voorhees et ai, August 1989. The 2003 report describes an updated computer model of the aquifer system in Collier County, Florida, with a concentration on the simulation of wellfield GMPpaper 2010 - Wellfield Protection Report V511-15-10.docx Paper Page 9 of33 Growth Management Plan protection areas and efforts in the determination of wellfield protection regions. The following is largely extracted from the Voorhees 2003 report. The purpose of the 2003 Voorhees investigation in Collier County was as follows: (1) To update a wellfield protection computer model of the aquifer system in Collier County; (2) To describe the effects of future ground water withdrawals on ground water flow in the vicinity of each study wellfields; (3) To describe the one (1), two (2), five (5), and twenty (20)-year diversion area (i.e., protection zones or travel times) associated with the annual permitted allocation rate for each study wellfleld; and (4) Provide extensive software development and training on this software to enable County staff the ability to update wellfield protection zones frequently. The diversion area is defined as the area, in plan view, through which ground water moves within the aquifer system to a production well in a prescribed number of years. All analyses were performed assuming steady-state conditions. The term "Study Area," as it was used in this 2003 report, refers to a 2,220 square-mile area included in the model and enclosed by the regional model grid. In addition, seven separate study wellfields were investigated as follows: City of Naples (East Golden Gate) - SFWMD Permit No. 1100018W; City of Naples (Coastal Ridge) - SFWMD Permit No. 1100017W; Collier County Utilities - SFWMD Permit No. 1100249W; Immokalee - SFWMD Permit No. 1100013W; Florida Cities Utilities (now Florida Governmental Utility Authority) - SFWMD Permit No. 1100148W; Everglades City - SFWMD Permit No. 1100160W; and Orangetree - SFWMD Permit No. 1100419W. The extent of the 2,220 square-mile study area encompasses approximately the western two thirds of Collier County, the southern third of Lee County, and a small part of southern Hendry County in south Florida. The north boundary divides the topographic high about 7 miles north of Lake Trafford. The south boundary is south of the major portion of Lower Tamiami Canal. The east boundary is located far east in Big Cypress Swamp to minimize boundary effects on regional flow. The west boundary is the Gulf of Mexico. An extensive general description of the study area hydrogeology is provided by Knapp et aI, 1986, Bennett, 1992, and Voorhees et aI, 1989. The reader should review Voorhees et aI, 1989, Section 3, and Bennett, 1992 for details associated with hydrogeologic data for the study area. The rock units from which most potable water is withdrawn in Collier County are grouped according to previously defined stratigraphic units and by their hydraulic properties. The sources of geologic and hydrologic data for Collier County, Florida as used in the model to the present are as follows: GMPpaper 2010 - Wellfield Protection Report V5 11-15-10.docx Paper Page 10 of 33 Growth Management Plan Information Source Canal system Collier County U.S. Geological Survey Bennett, 1992 Geologic structure Knapp et aI, 1986 Lee County study (Voorhees et aI, 1988) Bennett, 1992 Hydraulic aquifer characteristics Knapp et aI, 1986 Lee County study (Voorhees et aI, 1988) Collier County County utilities Bennett, 1992 Canal topology Municipal pumping well topology u.s. Geological Survey topographic maps Collier County South Florida Water Management District Bums and Shih, 1984 Knapp et aI, 1986 County utilities Municipal wellfield pumpages South Florida Water Management District Collier County Knapp et aI, 1986 County utilities Agricultural pumpage Knapp et aI, 1986 Collier County Collier County Agricultural Extension South Florida Water Management District Hydrologic investigations Knapp et aI, 1986 Bums and Shih, 1984 Jacob, 1983 Gee & Jensen, 1980 Swayze and McPherson, 1977 Bennett et aI, 1992 Voorhees et aI, August 1989 Calibration of the ground water model is critically important to modeling studies such as being described. For the 2003 modeling work the regional model calibration was performed by combining the calibration results from reports from Voorhees et aI, 1989 and Bennett, April 1992 (SFWMD). Voorhees et aI, 1989 calibrated a regional model to a course grid and used the regional model to establish boundary conditions for several wellfield submodels. The technique of computerized optimization was used to achieve calibration. Bennett, April 1992 used a coarse grid in manually calibrating a regional model, which extended in depth vertically to the Hawthorn aquifer. By GMPpaper 2010 - Wellfield Protection Report V511-J5-JO.docx Paper Page 11 of33 Growth Management Plan combining the calibrated parameters from these two studies and performing detailed grid optimization to place model nodes as close as possible near wells in a single regional model, the original Voorhees et aI, 1989 study with wellfield submodels has now been replaced with a single regional model. This provided a unified, streamlined, and easier wellfield protection modeling update procedure for Collier County staff. The deeper Hawthorn aquifer is now included in this model, which is an update as it was not part of the 1989 study, and as in the SFWMD model, the Hawthorn aquifer is configured as a fixed head boundary condition. Due to artesian conditions and extensive confining units above the Hawthorn aquifer, pumpage in the Hawthorn is assumed to not require wellfield protection analysis. The theory associated with the delineation of wellfield protection zones is presented by Voorhees et aI, 1989; Section 5 p29, and Section 11 p85. The reader is referred to that discussion for details of the procedure. The only departure in 2003 from that documented procedure is the initial placement of travel time particles at a production well over the entire producing aquifer, vertically. In the prior study by Voorhees et aI, 1989 particles were placed at the vertical midpoint of the producing aquifer. The result of this procedural enhancement has been made possible by the availability of more accurate travel time delineation and more powerful computing resources. Running of the model and hence delineation of the wellfield protection zones can be determined very easily by data entry of a few values that include the following: (1) an exactly two character well field identifier for the well-- user selected; (2) an exactly three character well identifier -- user selected; (3) the SFWMD permitted wellfield average annual allocation in MGD for the well-- obtained from utilities with confirmation from SFWMD; (4) the NAD83 Easterly and Northerly State Planar well coordinates in feet for the well-- based on GPS measurement by County or utility staff; (5) the aquifer from which the well pumps -- obtained from utilities; (6) the well pump capacity in GPM -- obtained from utilities with confirmation from SFWMD; and (7) comment regarding the well -- user selected. The item numbers coincide with the well data entry sequence for the software developed for this study. The wellfield protection pumpage for each well is then computed by the software developed for this project using the formula: Qi = Qwa(Qci/~iQci)/I440 (Eq 1) where: Qi is the wellfield protection pumpage for well in gallons per minute (GPM); Qwa is the SFWMD permitted wellfield average annual allocation in Millions of Gallons per Day (MGD); Qci is the pump capacity of well in the wellfield, gallons per minute (GPM); and ~iQci is the summation of all well capacities in the wellfield. GMPpaper 2010 - Wellfield Protection Report V511-15-10.docx Paper Page 12 of33 Growth Management Plan For this study these data were obtained from the various utilities by County staff and are presented in Appendix "B" with cross-references to the numbered items (1) through (7) listed above. For all well field protection simulations a conservative transport porosity of 0.15 was used to generate all ground water flow path lines. The methodologies used in the 2003 study are consistent with those previously applied by Voorhees et aI, 1989 and the guidelines published for determination of wellhead protection areas (U.S. Environmental Protection Agency, 1987). The use of wellfield protection zones provides a consistent planning tool for the County and the extensive software development performed for the project provides a user-friendly system for County staff to update and change wellfield protection areas. Significant improvement of computational resources since the Voorhees et aI, 1989 study provided improved accuracy for the determination of wellfield protection areas based on three dimensional ground water flow and the development of an integrated system which is more accessible by County staff. 2.3 MODELING OF 2004 The wellfield protection modeling undertaken in 2004 was carried out by Collier County staff; primarily Mr. Michael Lucas, Environmental Specialist. This modeling followed the methods described above and set up at that time on the county computers by the PCD's consultant, Dr. M.L.Voorhees. The data collection phase of the work took place between approximately May and September 2004, and the computer modeling was completed by November 2004. As described above the specially designed program suite comprises two linked computer codes: a hydrogeological model, and a freeware CAD program called IntelliCAD (a clone of AutoCAD). The wellfields covered in the 2004 modeling exercise included: Immokalee Well field Orangetree Wellfield Florida Governmental Utility Authority Golden Gate City Wellfield Everglades City Wellfield Collier County Utilities Wellfield - Golden Gate Well field City of Naples - East Golden Gate Wellfield City of Naples - Coastal Ridge Wellfield The results of the modeling provided the LDC required W-l, W-2, W-3, and W-4 protection zones for each wellfield. These zones were included in Collier County Ordinance No. 05-27 as Sub Section 3.0. Amendments to Section 3.06.06 Regulated Wellfields. 2.4 MODELING OF 2007 The necessary raw data for the 2007 modeling exercise was gathered from the public water supply wellfield owners and stakeholders in October and November 2006. The well field protection modeling undertaken in 2007 was carried out by PCD staff member Dr. Alister Burnett, Environmental Specialist. GMPpaper 2010 - Wellfield Protection Report V511-15-JO.docx Paper Page 13 of 33 Growth Management Plan The wellfields modeled in 2007 included: Immokalee Wellfield Orangetree Well field Ave Maria Utility Co. Wellfield City of Naples - Coastal Ridge Wellfield Everglades City Well field Collier County Utilities Well field City of Naples - East Golden Gate Wellfield Florida Governmental Utility Authority Golden Gate City Wellfield For the Everglades City Wellfield where there was no change in the input data from that used in 2004, the 2007 modeling resulted in exactly the same time path flowlines and, hence, the same one, two, five, and twenty year special treatment overlay Wellfield Protection Zones as the 2004 model. For the extensive City of Naples Coastal Ridge and East Golden Gate Wellfields, and the Immokalee Wellfield, although minor model input changes were applied because of minor well or pumping changes, the resulting Wellfield Protection Zones are unchanged from the 2004 modeling. For wellfields with new or significantly altered input data, new timeline flow path shapes files were generated resulting in new one, two, five, and twenty year Wellfield Protection Zones. This was the case for the Orangetree Wellfield, FGUA (Golden Gate) Wellfield, and Collier County Golden Gate Wellfield. The entirely new Ave Maria Wellfield input data was compiled and applied to the model, which then generated new one, two, five, and twenty year timelines; i.e., special treatment overlay Wellfield Protection Zones ST/W-l, ST/W-2, ST/W-3, and ST/W-4. A summary of the changes between the 2004 and 2007 modeling, which gave rise to the previous request for Amendments to the "Collier County Wellhead Protection Areas and Proposed Wellfields and ASRs Map" located within the Collier County Growth Management Plan's Future Land Use Element, are listed below.

MODELING OF 2010 LEADING TO 2010 LDC AMENDMENT REQUEST 3.1 STAKEHOLDERS The necessary raw data for the 2010 modeling was gathered from the public water supply wellfield owners and stakeholders in November 2009 and the wellfield protection modeling was carried out in early 2010 by PCD staff member Dr. Alister Burnett, Environmental Specialist. The wellfields modeled in 2010 included: Immokalee Well field Orangetree Wellfield Ave Maria Utility Co.Wellfield Port of the Islands Wellfield Florida Governmental Utility Authority Golden Gate City Wellfield Everglades City Well field Collier County Utilities Well field City of Naples - East Golden Gate Wellfield City of Naples - Coastal Ridge Wellfield The full listing of organizations and personnel that were the primary contacts for the 2010 modeling is provided as Appendix A. 3.2 METHODS The purpose of the 2010 modeling was, as before, to establish areas of increasing vulnerability surrounding each public wellfield that needed special protection from pollution. The methods used were exactly as described and used previously: collecting the relatively limited amount of input data; keying this data into the software; running the modeling software; generating the one, two, five, and twenty year particle flow path lines; drawing the shapes/polygons that surround each of these flow path shapes; and, copying and superimposing these zone shapes onto a base map of the county. These Wellfield Protection Zone maps then form the basis of the LDC content. 3.3 RESULTS An important issue that became clear with this modeling was that every wellfield experienced some change since the 2007 modeling. Many of the changes were relatively minor; e.g., one or two wells abandoned or new wells drilled, new pumps with changed capacities installed, SFWMD annual withdrawal allocation changes, revisions to provided well coordinates, etc. There was no wellfield with exactly the same Wellfield Protection Zone as for the 2007 modeling. Since 2007 the new shallow Port ofthe Islands Wellfield input data was compiled and applied to the model which then generated new one, two, five, and twenty year timelines; i.e., special treatment ovelay Wellfield Protection Zones ST/W-I, ST/W-2, ST/W-3, and ST/W-4. This new wellfield is included in Map 1 for the first time.

The WMP was developed because of a Growth Management Plan commitment to assess and protect water resources. The second draft of the Collier County Watershed Management Plan is attached. The summary and recommendations will be presented. The WMP consists of 3 parts; Volume I contains the executive summary, assessment of resources, and development of performance measures. Volume 2 provides the alternatives analysis and recommended projects. Recommended non structural initiatives are in Volume 3. General information and the original support documents for the WMP are available at our web page. The Collier County Watershed Management Plan second draft will be posted to the web page soon. Considerations: The WMP has been discussed at 13 EAC meetings since 2007. Implementation of the WMP is to be accomplished by utilizing existing staff to construct the ranked recommended projects (Table I) and non structural initiatives (Table 2) as time and existing budget allow. Implementation of the projects is to be accomplished with existing stormwater budget, partnering, and grants as funds become available following Lely Area Stormwater Improvement Project completion. The projects can be phased into the Capital Project schedule as budget permits. Non structural initiatives are to be implemented by developing policy, standards, and or criteria in scheduled LDC and Growth Management Plan amendment cycles utilizing existing staff, committees and with only minor consulting technical assistance. A general strategy for implementing the non-structural initiatives is presented in Volume 2. The Low Impact Development Program will be an incentive based program where Land Development Code (LDC) requirements will be relaxed to encourage the Low Impact Development (LID) components. The Flood Protection Level of Service (LOS) program will be contingent on acceptance of the alternate base standard and analysis of the standards in the policy development. The Florida Friendly Fertilizer Ordinance was developed separately from the report and is not included in the WMP. Table 1. Pro'ects ranked b estimated Benefit to cost ratio.

Structural Projects may be implemented as Growth Management Division Office of Land Development - Stormwater and Environmental Planning Section storm water funds, partners, or grants become available. The implementation of the plans will be cost neutral. GROWTH MANAGEMENT IMPACT: Completion of the WMPs will support objective 2.1 of the Conservation and Coastal Management Element of the County Growth Management Plan. RECOMMENDATION: That the EAC recommend the following cost neutral and incentive based initiatives are implemented. 1. Implementation of the ranked projects in Table 1 as funding can be obtained using existing Stormwater budget funds, grants, and by partnering with other entities. 2. Develop a LID program with existing staff by creating LDC incentives to encourage and offset any additional startup or operational costs. Focus will be on techniques that maximize water quality and recharge benefits. 3. Start a Storm water Treatment System Retrofit program to upgrade public systems with LID and other techniques to maximize water quality and recharge benefits as grants and storm water budget funds are available. 4. Consider switching to a Fee-Based Stormwater Utility that could create incentives for improved water quality treatment and recharge. Structure of the fees would not increase the total revenues but would reward users with effective treatment systems. This initiative would require an initial fee rate study that would be funded by grant or from existing storm water funds. 5. Utilizing existing staff develop flood protection LDC requirements for stormwater treatment system standards proposed in Initiatives 4, 5, and 6 from Table 2 to prevent increased flooding risk to downstream properties. 6. Consider changing the Flood Protection LOS standard by utilizing existing staff to analyze the proposed system to insure it has the intended benefit of expanding the range of grading and identifying critical areas for improvement. IF analysis is positive develop an implementation plan to amend the standards in the Growth Management Plan. 7. Develop a North Golden Gate Estates (NGGE) Transfer of Development Rights program within the North Golden Gates Flowway Restoration Area to encourage restoration of ecologically valuable lands, and improve recharge of surficial aquifers. This will be accomplished utilizing existing staff and an oversight committee to determine if there is support for the program. Final acceptance of the program will be through EAC, and Collier County Planning Commission reviews and BCC approval. 8. Develop a NGGE mitigation program to ensure stormwater treatment, and floodplain storage capacity within the basin is not lost. This will be a pilot program that can be utilized in other basins if it is effective. Existing staff will work alternatives through the review process during the nest Golden Gate Master Plan revision. 9. To maximize ground water recharge, improve water quality, and reduce ground water discharge to the canal network staff will work with South Florida Water Management and Big Cypress Basin staff to improve the operation and or design of the Water Control Structures in future planned basin and structure evaluations. 10. Refinement of the existing Water Quality Monitoring program to add additional stations and include focused stormwater runoff sampling will be accomplished through contract negotiation with partners, reevaluation of the existing monitoring program, and or grant opportunities. 11. Existing staff will work with state and federal partners to develop the Additional Watershed Protection Program as storm water funds and or grants are available. This program includes efforts to encourage storage and treatment of stormwater in fallow agriculture areas and undeveloped estates lots to improve water quality, recharge and delivery of fresh water to the Growth Management Division Office of Land Development - Stormwater and Environmental Planning Section estuaries. The other component of the program is to reevaluate the preservation standards in rural fringe neutral areas with identified ecologically valuable lands. 12. A Stormwater treatment system certification program will be developed by existing staff utilizing guidance in the draft State Stormwater Quality Applicant's Handbook and Conservation and Coastal Management Element Policy 2.2.5 in the next LDC or as an alternative staff could be directed to modify CCME Policy 2.2.5 through the EAR Based amendments to eliminate this requirement. 13. Develop a Florida-Friendly Fertilizer Use on Urban Landscapes ordinance and complimentary public education program utilizing existing staff.
