Agenda 01/08/2019 Item #17A01/08/2019 EXECUTIVE SUMMARY Recommendation to adopt a Resolution proposing amendment to the Collier County Growth Management Plan, Ordinance 89-05, as amended, specifically amending the Potable Water Sub- Element of the Public Facilities Element to amend Policy 1.7 to reference the updated Ten-Year Water Supply Facilities Work Plan, and furthermore directing transmittal of the amendment to the Florida Department of Economic Opportunity. (Transmittal Hearing). (PL20180002552/ CPSP- 2018-6) OBJECTIVE: The objective of this petition is to have the Board of County Commissioners (BCC) consider a request to amend the County’s Growth Management Plan (GMP) to modify the reference to the updated Ten-Year Water Supply Facilities Work Plan with the new date, as required by Se ction 163.3177(6)(c), Florida Statutes, as well as to consider directing transmittal of the amendment to the Florida Department of Economic Opportunity (DEO). CONSIDERATIONS: The Florida Water Resources Act (Chapter 373, F.S.) requires the five water management districts to provide regional water supply planning in all areas of the State to meet future projected demands. Each regional water supply plan is based on at least a 10 -year future planning horizon, and a complete update of each plan is required every 5 years. The purpose of regional water supply planning is to develop strategies to meet future water demands of urban and agricultural uses, while meeting the needs of the environment. This process identifies historical uses of water and water source options to meet potential shortfall. Florida Statutes Section 163.177(6)(c) requires local governments to prepare a Ten -Year Water Supply Facilities Work Plan and adopt revisions to comprehensive plans within 18 months following the approval of the most current version of the applicable regional water supply plan. Collier County is within the water supply planning area under the purview of the South Florida Water Management District (SFWMD). On February 24, 2009, the County adopted its first Ten-Year Water Supply Facilities Work Plan, by Ordinance No. 09-04, based on the guidelines of the 2005-2006 Lower West Coast Plan Update. The most recently revised 2017 Lower West Coast Water Supply Plan Update was approved by the SFWMD Governing Board on December 14, 2017. This plan assesses projected water demands and potential sources of water for the period through 2040. Therefore, Collier County must adopt their updated plan by June 14, 2019, 18 months after SFWMD adopted the latest Plan Update. The proposed 10-Year Water Supply Facilities Work Plan update addresses the following objectives: Identifies population and water demands of the County and each utility for the planning period, 2019 to 2028. Presents existing and planned potable and reclaimed water facilities that will be utilized to meet demand projections. Identifies sources of raw water needed for potable water and irrigation water supply to meet demands through the year 2028. Identifies the steps necessary to develop additional potable and reclaime d water supplies and specifies when they must occur and how they will be funded. Demonstrates that the water supply plans for each utility within the County are feasible with respect to facility capacity to be developed and consumptive use permit allocations required. Describes the conservation practices and regulations utilized by each utility to meet water supply demand. After the initial transmittal of the GMP Amendment for the Ten-Year Water Supply Facilities Work Plan 17.A Packet Pg. 1778 01/08/2019 to the Department of Economic Opportunity and their 30-day review period, comments (if any) are sent back to the Chairman of the Board of County Commissioners; and subsequently, staff revises the amendment as necessary. The adoption process for the GMP amendment follows these revisions with staff bringing the amendment back through both the Planning Commission and the Board of County Commissioners for adoption public hearings. NEIGHBORHOOD INFORMATION MEETING (NIM) SYNOPSIS: A Neighborhood Information Meeting (NIM) is not required by Section 10.03.05.F of the LDC for Growth Management Plan amendments which are not site specific. COLLIER COUNTY PLANNING COMMISSION (CCPC)/ENVIRONMENTAL ADVISORY COUNCIL (EAC) RECOMMENDATION: The CCPC, sitting in its capacity as the local planning agency under Ch. 163.3174, F.S., and also sitting as EAC, heard this petition, at their December 6, 2018 meeting, and voted 6-0 to forward the subject petition to the BCC with a recommendation to transmit to DEO. The Planning Commission brought up a number of concerns with the Work Plan and requested staff address their comments. Public Utilities has compiled a table listing the Planning Commission’s comments and how each will be addressed (Attachment A). As noted at the meeting, Public Utilities provided a copy of the Work Plan to the SFWMD for review in November. Public Utilities received comments from the SFWMD on December 14, 2018 and responded to those comments on December 21, 2018 (Attachment B). FISCAL IMPACT: None LEGAL CONSIDERATIONS: This Growth Management Plan (GMP) amendment is authorized by, and subject to the procedures established in, Chapter 163, Part II, Florida Statutes, The Community Planning Act, and by Collier County Resolution No. 12-234, as amended.

REQUESTED ACTION: The proposed text change seeks to amend the Potable Water Sub-Element of the Public Facilities Element to update the reference to our next Ten-Year Water Supply Facilities Work Plan, as required of Collier County government by Section 163.3177(6)(c), Florida Statutes. Policy 1.7 is proposed to be amended as follows: [Note: Current Potable Water Sub-Element language appears below in plain text, the proposed amendment is shown in strike-through/underline format. Objective 1 of the Sub-Element is included for background/clarity purposes] 17.A.1 Packet Pg. 1781 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 2 Proposed Potable Water Sub-Element Text Amendment: [page 2] OBJECTIVE 1: Locate and develop potable water supply sources to meet the future needs of the County owned and operated systems, said supply sources meeting the minimum Level of Service Standards established by this Plan. The development and utilization of new potable water supply sources and the acquisition of land necessary for such development shall be based upon the information, guidelines and procedures identified within the County’s Ten-Year Water Supply Facilities Work Plan (as updated) and the Lower West Coast Water Supply Plan prepared by the South Florida Water Management District. [Note: No revisions to Policies 1.1 through 1.6 are proposed.] Policy 1.7: The County has developed the Ten-Year Water Supply Facilities Work Plan, dated October 2013 November 2018, in accordance with the water supply guidelines of the most current version of the South Florida Water Management District’s Lower West Coast Water Supply Plan. The County’s Ten-Year Water Supply Facilities Work Plan is incorporated herein by reference. STAFF ANALYSIS: As indicated in Policy 1.7 of the Public Facilities Element, Potable Water Sub-Element, the County has developed the Ten-Year Water Supply Facilities Work Plan (Appendix A). The proposed text amendment seeks to adopt the updated version of the County’s plan, which has been prepared in accordance with the most current version of the South Florida Water Management District’s Lower West Coast Water Supply Plan. The updated version of the Ten- Year Water Supply Facilities Work Plan is proposed for incorporation into the County’s GMP by reference. Regional Planning: In December 2017, the Governing Board of the South Florida Water Management District (SFWMD) approved the 2017 Lower West Coast Water Supply Plan (LWCWSP) Update. Under Florida law (section 163.3177(6)(c), Florida Statutes) Collier County must adopt amendments to its comprehensive plan within 18 months of the SFWMD approval of the update. These amendments include the development of an updated 10-Year Water Supply Facilities Work Plan and amendments to the Growth Management Plan (GMP). The LWCWSP amendment required the five water management districts to initiate regional water supply planning in all areas of the State. The purpose of regional water supply planning is to develop strategies to meet future water demands of urban and agricultural uses, while meeting the needs of the environment. This process identifies historical uses of water and water source options to meet potential shortfall. Each regional water supply plan is based on at least a 10-year future planning horizon, and a complete update of each plan is required every five years. 17.A.1 Packet Pg. 1782 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 3 The Lower West Coast Water Supply Planning Area includes Lee County and portions of Charlotte, Collier, Glades, Hendry and Monroe counties. The 2017 Lower West Coast Water Supply Plan Update (LWC Update) was approved by the SFWMD Governing Board in December 2017. The LWC Update assesses projected water demands and potential sources of water for the period through 2040. Source: 2017 Lower West Coast Water Supply Plan Update 17.A.1 Packet Pg. 1783 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 4 Local Planning: On February 25, 2003 the Board of County Commissioners adopted an update to the County’s 2001 Water Master Plan, to provide an integrated approach for meeting the projected water system demands up to the year 2022. The “2002 Water Master Plan Update” provided for comprehensive overview of the entire water system, including emergency systems, water demand projections and demands and proposed conservation and reclaimed water projects, and provided a plan for future water supply and infrastructure needs to meet the requirements of growth, infrastructure renewal, replacement and enhancement over a course of five years. Water demands were provided at five-year increments to be consistent with the 2000 Lower West Coast Regional Water Supply Plan. During the State of Florida’s 2005 legislative session, lawmakers revised state water law to include a new statutory provision. Local governments within the Lower West Coast Planning Area are required to prepare a Ten-Year Water Supply Facilities Work Plan that identifies water supply projects and adopt revisions to comprehensive plans within 18 months following the approval of the most current version of the Lower West Coast Water Supply Plan Update. On January 25, 2007, as part of the 2004 Evaluation and Appraisal Report (EAR) based amendments, and in preparation of the anticipated Ten-Year Water Supply Facilities Work Plan, Collier County adopted language to coordinate water supply planning with SFWMD. Modifications of various Goals, Objectives and Policies (GOPs), as required by these legislative actions, were addressed through the GMP amendment to the Potable Water Sub-Element, the Conservation and Coastal Management Element and the Intergovernmental Coordination Element. The amendments referenced the 2002 Water Master Plan Update and any updates as the County’s water supply planning document. During the County’s 2011 EAR-based amendments, references to the County’s 2002 Water Master Plan document were further revised to note the adopted Ten-Year Water Supply Facilities Work Plan (dated October 2008) as the County’s appropriate document for water supply planning. On February 24, 2009, the County adopted its first Ten-Year Water Supply Facilities Work Plan, by Ordinance No. 09-04. It was based on the guidelines of the 2005-2006 Lower West Coast Plan Update, subsequently adopted. In December 2017, the SFWMD’s Governing Board approved the 2017 Lower West Coast Water Supply Plan Update. Therefore, Collier County must adopt the proposed GMP text amendment that references the proposed Ten-Year Water Supply Facilities Work Plan by May 15, 2019 (or 18 months after the District Governing Board approved each regional water supply plan) [s. 163.3177(6)(c), F.S.]. 17.A.1 Packet Pg. 1784 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 5 Proposed 10-Year Water Supply Facilities Work Plan update: As noted in the attached 10-Year Water Supply Facilities Work Plan, the updated document addresses the following objectives: • Identifies population and water demands of the County and each utility for the planning period, 2019 to 2028. • Presents existing and planned potable and reclaimed water facilities that will be utilized to meet demand projections. • Identifies sources of raw water needed for potable water and irrigation water supply to meet demands through the year 2028. • Identifies the steps necessary to develop additional potable and reclaimed water supplies and specifies when they must occur and how they will be funded. • Demonstrates that the water supply plans for each utility within the County are feasible with respect to facility capacity to be developed and consumptive use permit allocations required. • Describes the conservation practices and regulations utilized by each utility to meet water supply demand. The population methodology used for the 10-Year Water Supply Facilities Work Plan is based on the County’s latest adopted Annual Update Inventory Report and Capital Improvement Element (AUIR-CIE) available at the time the plan was created (2018 AUIR-CIE). Please note that because of updates to data, the proposed Ten-Year Water Supply Facilities Work Plan will differ from the 2017 Lower West Coast Plan Update, as well as the most recent AUIR-CIE documents. These variances have been vetted with SFWMD staff, who agrees that the population methodology is appropriate. This 10-Year Water Supply Facilities Work Plan was prepared by the County’s consultant, CDM Smith, in coordination with Public Utilities Department and Growth Management Department staff, as well as representatives from various private utilities, and includes the areas of the County served by the Collier County Water and Sewer District, the Ave Maria Utility Company (AMUC), and the Immokalee Water and Sewer District (IWSD). Also referenced in the plan are the Lee Cypress Water and Sewer Co-Op, Inc, and the Port of The Islands Community Improvement District, as well as a number of small capacity water systems regulated by the Florida Department of Environmental Protection (FDEP) (see pages 2-6 and 2-7 of the attached plan). These did not meet the minimum size requirements to be included. In substance, the CCWSD portions of the Plan update provide detail behind the following broad subject areas: (a) Existing Facilities (Section 4): The CCWSD is served by three water treatment plants, the North County Regional Water Treatment Plant, the South County Regional Water Treatment Plant, and the Orange Tree Water Treatment Plant, with maximum finished water production capacities of 20 MGD, 32 MGD, and 0.75 MGD respectively. Four wellfields provide raw water for the plants, drawing from both brackish and non-brackish 17.A.1 Packet Pg. 1785 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 6 sources. Collier County has been a leader in the use of brackish water source production. Along with these production and wellfield facilities, the CCWSD contains over 1,000 miles of transmission and distribution pipelines, water storage tanks, pumping facilities, an aquifer storage and recover (ASR) system and approximately 56,000 individual service connections. In addition, the CCWSD operates one of the largest irrigation quality (IQ) water systems in south Florida. With contractual commitments of over 23 MGD to golf courses communities, parks and roadway medians, there is additional potential demand of over 28.5 MGD represented by communities that have been dual-piped. (b) Planned Water Supply Facilities (Section 5): Based on the 2018 AUIR population and Level of Service (LOS) standard, the Plan update indicates 2027 as the optimal first production year for the new Northeast Regional Water Treatment Plant Wellfield Phase 1. Components of this regional improvement include the Phase 1 Water Treatment Plant, the Phase 1 wellfield, and all associated transmission pipelines, pumps and water storage tanks. The District’s IQ water system will be enhanced by the development of 5 ASR wells that will allow storage of IQ water in the wet season for use in the dry season. Additional sources of IQ supply will be addressed, through permit allocations of groundwater and capture and storage of surface water. (c) Facilities Capacity Analysis (Chapter 6): Plans to bring online a new potable water treatment facility and associated wellfield during the 10-year period will allow CCWSD to stay ahead of the demand curve during the 10-year planning period. (d) Conservation (Section 7): Conservation measures have been an important element in CCWSD planning for many years. Local regulations on domestic irrigation, low flow devices, Florida Friendly landscape principles, Fridays are Dry Days, and a block rate structure have been employed and will be continually improved. A meter replacement program is now underway, and efficiency gains at the Regional Plants and throughout the Distribution system are being realized. (e) Capital Improvement Projects (Section 8): Subsections present the capital improvement projects planned by each utility, including the funding source, project number, project name, and cost estimate for each project. A depiction of the District boundaries for each of the covered utilities follows. 17.A.1 Packet Pg. 1786 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 7 Source: Collier County 10 Year Water Supply Plan Update (Draft), October 2018 17.A.1 Packet Pg. 1787 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 8 Statutory Requirements: The Department of Economic Opportunity (DEO) has published “A guide to Preparation of the Water Supply Facilities Work Plan”. Local governments must comply with the following statutory requirements for water supply and facility planning (Each requirement followed by staff comment in bold and italics): 1. Coordinate appropriate aspects of their comprehensive plan with the appropriate water management district's regional water supply plan. [Section 163.3177(4)(a), F.S.]. The current GMP contains Goals, Objectives, and Policies (GOPs) that had been adopted with the purpose of maintaining coordination with the SFWMD’s water supply plan. 2. Revise the Potable Water Sub-Element to adopt a water supply facilities work plan covering at least a 10-year planning period to meet existing and projected demand. The work plan should address those water supply facilities for which the local government has responsibility and include the facilities needed to develop alternative water supplies. The work plan should also identify conservation and reuse measures to meet future needs. [Section 163.3177(6)(c), F.S.] Policy 1.7 of the Potable Water Sub-Element was amended by Ordinance 09-04 to incorporate by reference the County’s 10-Year Water Supply Facilities Work Plan. This proposed GMP amendment seeks to adopt the revised update to the plan, which identifies: the County’s traditional and alternative water supply sources to meet existing and projected needs for the a 10- year period; the capital improvements that will be needed to develop, treat, and deliver those alternative supplies; and the conservation measures and reuse supplies utilized to offset demand for new water. The County also updates its Capital Improvement Element on a yearly basis through the AUIR-CIE to include the capital improvements needed in the first five years of the 10-Year Water Supply Facilities Work Plan. 3. Revise the Conservation Element to assess current and projected water needs and sources for at least a 10-year planning period. The analysis must consider the existing levels of water conservation, use, and protection and the applicable policies of the water management district, and the district’s approved regional water supply plan. In the absence of an approved regional water supply plan, the analysis must consider the district’s approved water management plan. [Section 163.3177(6)(d)3, F.S.] The current Conservation and Coastal Management Element of the GMP contains Goals, Objectives, and Policies (GOPs) that consider the SFWMD’s levels of water conservation, use, and protection. 4. Revise the Capital Improvements Element to identify capital improvements projects to be implemented in the first 5 years of the work plan for which the local government is responsible, including both publicly and privately funded water supply projects necessary to achieve and maintain adopted level of service standards; and adopt a 5-year schedule of capital improvements to include those projects as either funded or unfunded, and if unfunded, given a level of priority for funding. [163.3177(3)(a)4, F.S.] The County 17.A.1 Packet Pg. 1788 Attachment: CCPC Staff Report_CPSP-18-6_FNL (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Agenda Item #9.A.4 PL20180002552/CPSP-2018-6 Ten-Year Water Supply Facilities Work Plan – Potable Water Sub element of the Public Facilities Element 9 updates its Capital Improvement Element on a yearly basis through the AUIR-CIE to include the capital improvements needed in the first five years of the 10-Year Water Supply Facilities Work Plan. 5. Revise the Intergovernmental Coordination Element to adopt principles and guidelines to be used to coordinate the comprehensive plan with the regional water supply authority (if applicable) and with the applicable regional water supply plan. [163.3177(6)(h)1, F.S.] The current Intergovernmental Coordination Element of the GMP contains Goals, Objectives, and Policies (GOPs) that provide principles and guidance for coordination with the SFWMD and other public and private utilities in regard to water supply planning. 6. During the Evaluation and Appraisal review, determine if comprehensive plan amendments are necessary to reflect statutory changes related to water supply and facilities planning since the last update to the comprehensive plan. If necessary, transmit the amendments to incorporate the statutory changes as appropriate. [Section 163.3191(1) and (2), F.S.] The recently adopted County’s EAR-based amendments included revisions to several of its Elements (not related to statutory changes) to revise references to the County’s 2014 Water and Wastewater Master Plan Update document and include the adopted Ten-Year Water Supply Facilities Work Plan, the Lower West Coast Water Supply Plan and the Water Master Plan as the County’s appropriate documents for water supply planning. NEIGHBORHOOD INFORMATION MEETING (NIM) SYNOPSIS The Collier County Land Development Code Chapter 10.03.00: Notice Requirements, establishes the required methods of providing public notice procedures and refers to Chapter 8 of the Collier County Administrative Code for Land Development (2018), which addresses information relating to public notice requirements for land use petitions (including when a Neighborhood Information Meeting is required.) The Administrative Code states, “The NIM is only for site-specific amendments.” This project is not a site-specific amendment, therefore no NIM was held.

Under Florida law (section 163.3177(6)(c), Florida Statutes) Collier County must adopt amendments to its comprehensive plan within 18 months of the SFWMD approval of the update. These amendments include the development of a 10-Year Water Supply Facilities Work Plan and amendments to the Growth Management Plan (GMP). Under the requirement of the Florida Statutes, the 10-Year Water Supply Facilities Work Plan for Collier County must include analysis of all water utilities in the County not serving a specific local government. These utilities include: Collier County Water-Sewer District (CCWSD) Immokalee Water and Sewer District (IWSD) Ave Maria Utility Company, LLLP (AMUC) Utilities not included in this Plan are the City of Naples Utility Department, Marco Island Utilities, and Everglades City, each of which is responsible to develop a 10-Year Water Supply Facilities Work Plan to be included in its city’s comprehensive plan. This 10-Year Water Supply Facilities Work Plan Update for Collier County has the following objectives: Identify population and water demands of the County and each utility for the planning period of 2019 to 2028. Present existing and planned potable and reclaimed water facilities that will be utilized to meet demand projections. Identify sources of raw water needed for potable water and irrigation water supply to meet demands through the year 2028. Identify the steps necessary to develop additional potable and reclaimed water supplies and specify when they must occur and how they will be funded. Demonstrate that the water supply plans for each utility within the County are feasible with respect to facility capacity to be developed and consumptive use permit allocations required. Describe the conservation practices and regulations utilized by each utility to meet water supply demand. The Collier County 10-Year Water Supply Facilities Work Plan Update was prepared by CDM Smith Inc. (CDM Smith) for the Collier County Growth Management Division. Executive Summary · ES-2 PW/6295/231366/03/01 Information for the Plan Update was solicited from each of the utilities included. All three utilities provided some level of information for inclusion in the Plan. Where information gaps existed, information on the existing and planned facilities was gathered from various sources including the SFWMD LWCWSP update, SFWMD consumptive use permits, Florida Department of Environmental Protection (FDEP) public water supply and wastewater treatment facility permits, and the previous Collier County 10-Year Water Supply Facilities Work Plan, adopted in February 2014. After completion of the draft version of the Plan Update, copies were distributed to each of the utilities for review and comment. Comments provided by each of the utilities were incorporated into their sections of the Plan Update. The findings of the Plan Update are summarized below for each of the utilities. Collier County Water-Sewer District (CCWSD) During the 10-year planning period CCWSD has plans to develop a new potable water treatment facility to meet growing water demands. Table ES-1 summarizes the treatment capacity of the existing and planned potable water and water reclamation facilities for CCWSD. Table ES-1.

It is important to note that other planning documents such as Water, Wastewater and Irrigation Master Plans as well as User and Impact Fee Rate Studies are ongoing. Likewise, concurrency tools such as the 2018 Annual Update and Inventory Report were not adopted by the Board of County Commissioners until after supporting data for this Plan was provided. Accordingly, planned facilities (see Chapter 5) may move up or back within the 10-year timeframe depending on these plans and studies, as adopted. The information supporting this 10-Year Water Supply Facilities Work Plan reflects the most recent data available as of July 1, 2018. 1.4 Plan Contents Section 2 introduces the individual utilities and systems that serve Collier County and identifies their service areas. Section 3 presents population and water demand projections for the County and individual utilities for the planning period out to 2028. Section 4 summarizes the existing potable water supply system including fresh and brackish water wellfields, raw water transmission systems, water treatment plants (WTPs) and reclaimed water systems (where Section 1 · Introduction 1-3 PW/6295/231366/03/01 applicable) for each utility. Section 5 summarizes the planned potable and reclaimed water systems for each of the utilities out to 2028. Section 6 presents an analysis of the ability of each utility to meet projected demands during the planning period. Section 7 summarizes current and planned conservation practices and regulations that will be utilized to meet demands. Section 8 summarizes the capital improvement plan for each of the utilities. 2-1 PW/6295/231366/03/01 Section 2 Water Service Areas 2.1 Overview of Collier County Collier County is served by four Public Sector Water Systems, including the County, the City of Naples, Everglades City, and the City of Marco Island. The County is served by the Collier County Water-Sewer District (CCWSD) and domestic self-supply outside of the CCWSD service area. The boundaries of the CCWSD, City of Naples, Everglades City and the City of Marco Island are shown in Figure 2-1. In addition to the Public Sector Water Systems, Collier County is served by two Non- Public Sector Water Systems including the Immokalee Water and Sewer District (IWSD) and the Ave Maria Utility Company (AMUC). The boundaries of these systems are also presented in Figure 2-1. There are also two Private Sector Water Systems which include the Lee Cypress Water and Sewer Co- Op, Inc. and the Port of the Islands Community Improvement District, along with numerous small capacity water systems that are regulated by the Florida Department of Environmental Protection (FDEP). 2.2 Individual Utilities and Systems 2.2.1 Collier County 2.2.1.1. Collier County Water-Sewer District (CCWSD) The CCWSD’s water service area currently encompasses approximately 199.93 square miles while its current wastewater service area encompasses 206.89 square miles. This area is bounded on the North by Lee County, on the south by the City of Marco Island service area, on the west by the City of Naples service area and the Gulf of Mexico, and on the east by the Urban Planning Boundary. The CCWSD was approved by referendum in 1969 and validated by the State Legislature in 1978 by Special Act, Chapter 78-489, Laws of Florida. In 1988, the legislature approved a supplement to the Special Act, which included revisions to the District boundaries. This action significantly increased the size of the District to approximately 210 square miles. It also specifically excluded areas of the City of Naples, Marco Shores, Marco Island, and the Florida Governmental Utility Authority (FGUA). The CCWSD acquired the Golden Gate City potable water and wastewater utility systems from the FGUA on March 1, 2018. The Orange Tree Utility Company (OTUC) was taken over by the CCWSD in 2014. There is one portion of the CCWSD service area that is not served by CCWSD, that being approximately 17 square miles of unincorporated area contiguous to the City of Naples, shown with the red hatch on Figure 2-1. As this area is a substantially developed part of the County, with minimal growth expected during the 10-year planning period, no plans for supplying additional water to this area are included in this Plan. The original interlocal agreement by which the City of Naples serves this area was enacted on October 16, 1977. A copy of the most recent version of the interlocal agreement is provided in Appendix A. Section 2 · Water Service Areas 2-2 PW/6295/231366/03/01 A composite map, provided as Figure 2-2, showing the existing CCWSD potable and reclaimed water distribution systems, illustrates the actual extent of the water-sewer district currently being served. In addition to interconnections with Marco Shores by which CCWSD supplies water on a bulk basis, CCWSD also maintains emergency interconnects with the City of Naples, the City of Marco Island and Bonita Springs Utilities. As the interconnects are for emergency purposes only and are not intended for bulk transfer, CCWSD does not dedicate any portion of its water supply capacity to serving these interconnections. Should CCWSD, at a future date, enter into an agreement with any additional entity to provide finished water, it will incorporate the amount of water provided to said entity into its planning documents. 2.2.1.2 Goodland Water Sub-District Until recently, the Goodland District was a separate water district serving an island community, roughly one quarter of a square mile in area. It is located about two miles east of Marco Island. The District was established by referendum in 1975. In 2012, the County abolished the District as a separate entity, thereby making it part of the CCWSD (Ord. 2012-43) Appendix B. Service to Goodland is supplied by CCWSD in all respects; bulk water is purchased for distribution from the Marco Island Utility. Accordingly, it is often referred to as a “sub-district,” although it is entirely within the CCWSD boundary. A copy of the Interlocal Agreement for the provision of water from the City of Marco Island is found in Appendix C. CCWSD maintains pumping, distribution and storage facilities in the Goodland sub-district; CCWSD serves the community of Key Marco as well as Goodland on the same basis. 2.2.2. City of Naples The City of Naples is another public sector provider of water service in Collier County. In addition to its corporate area, the City also serves approximately 17 square miles of unincorporated area contiguous to the City limits per an interlocal agreement with Collier County. There are approximately 6,178 service connections in the unincorporated area with an average daily demand of 4.17 MGD. The City allocates 33 percent of its system capacity to serve this unincorporated area. As the unincorporated area is built-out, no additional demand on the City’s system is projected for the future. The enabling legislation, under which the City established its water service area boundary, is Chapter 180, F.S., Municipal Public Works Law. The City's existing water supply facilities are not addressed in this 10-Year Water Supply Facilities Work Plan, since they will be discussed in the City's Plan. The service area for the utility is shown in Figure 2-1. 2.2.3 Everglades City Everglades City is also a public sector provider of water service in the County. Like Naples, Everglades City is an incorporated community that provides water service both within and beyond its corporate limits.

Unlike the unincorporated area served by the City of Naples, Plantation Island and Seaboard Village are not part of the Collier County Water Sewer District. For this reason, Collier County is not responsible to provide planning efforts to supply water to these communities. These areas are analogous to the Golden Gate Estates portion of Collier County, which is served entirely by self-supply, for which the County is not responsible for providing service. Everglades City's water supply facilities are not addressed in this 10-Year Water Supply Facilities Work Plan, since they will be discussed in the City's Plan. The service area for the utility is shown in Figure 2-1. 2.2.4 City of Marco Island Water and Sewer Service Areas The City of Marco Island historically had been provided service from the private sector utility company, the Florida Water Services Corporation. A small portion of Marco Island’s water and sewer infrastructure had historically been maintained by Collier County as the Marco Island Water and Sewer District. The City of Marco Island purchased the system from the Florida Water Services Corporation. The City operates the approximately 10 square mile system as a public sector utility. On February 24, 2004, the Marco Island Water and Sewer District was dissolved/abolished by Ordinance No. 2004-09. The infrastructure in that area was turned over from the CCWSD to the City. The City now owns and operates the only centralized utility services on Marco Island. The City’s existing water supply to the Marco Shores area was replaced with a bulk water supply from the CCWSD to service the area. The daily water demand (metered water) for the Potable Water Bulk Services to Marco Island is approximately 165,000 gallons per day and is accounted for in CCWSD’s population and water supply demand projections. As the Marco Shores area is built-out, no additional demand on the CCWSD system is projected for the future. Though outside of the scope date for this update, it should be noted that on September 26, 2018 the City of Marco Island provided a letter of intent to terminate the Potable Water Bulk Services Agreement on September 26, 2019 found in Appendix D. The City of Marco Island’s existing water supply facilities are not addressed in this 10-Year Water Supply Facilities Work Plan, since they will be discussed in the City's Plan. The service area for the utility is shown in Figure 2-1. 2.2.5 Immokalee Water and Sewer District (IWSD) The Immokalee Water and Sewer District (IWSD), located in the northeast part of Collier County, was created by Special Act of the State Legislature following a 1978 referendum. Creation of an independent district provided the means for this unincorporated community to develop its own water/sewer system, which was necessary due to the distance from the developed coastal area of the County. The boundaries of the District were expanded following a voter referendum in 2004 and a change to the enabling act was signed by the Governor in June 2005 (Chapter 2005-298). This district has a governing board whose members are appointed by the Governor of Florida. The boundaries of this independent district are shown on Figure 2-1. 2.2.6 Ave Maria Utility Company, LLLP (AMUC) Ave Maria Utility Company (AMUC), established in 2005, provides potable and reclaimed water service to the Town of Ave Maria. The town is located approximately 20 miles east of Interstate 75. The AMUC service area boundary is shown in Figure 2-1. Section 2 · Water Service Areas 2-6 PW/6295/231366/03/01 2.2.7 Independent Districts 2.2.7.1 Lee Cypress Water and Sewer Co-op, Inc. The private sector utility providing water service to Copeland is the Lee Cypress Water and Sewer Co-op, Inc. The unincorporated community of Copeland is located on SR-29 about 3 miles north of US-41. According to the SFWMD consumptive use permit for the Co-op, the population of the service area is projected to be 445 in 2024. Based on FDEP records, the utility currently has a capacity of 80,000 gpd. Between 2004 and 2025 the population of the community is projected to grow to 445 residents, according to the consumptive use permit. Using a straight-line interpolation of the growth rate in the consumptive use permit, the population would be projected to grow to 479 residents by 2028. Assuming a per capita water demand of 150 gpcd, the required utility capacity needed in 2028 would be 71,850 gpd. Based on the projected population and assumed per capita demand, the utility should continue to meet the needs of its residents without expansion through the 10-year planning period. Therefore, no additional consideration is given to this utility in the Plan. 2.2.7.2 Port of the Islands Community Improvement District Another independent district in the County is the Port of the Islands Community Improvement District. This district encompasses approximately 1 square mile of land contiguous to and north and south of US-41, approximately 20 miles south of Naples. This district was created in 1986 by the Collier County Board of County Commissioners in response to a petition from the District’s developers and was created as a mechanism to provide water and other services to this isolated area. The District is governed by an elected board of directors. The population of the District was 588 according to the 2017 LWCWSP. Based on FDEP records, the utility currently has a capacity of 440,000 gpd. Based on the projections in the 2017 LWCWSP, between 2010 and 2040 the population of the District is projected to grow to 641 residents. Assuming a per capita water demand of 142 gpcd, the required utility capacity needed in 2028 would be 91,022 gpd. Based on the projected population and assumed per capita demand, the utility should continue to meet the needs of its residents without expansion through the 10-year planning period. Therefore, no additional consideration is given to this utility in the Plan. 2.2.8 Water Systems Regulated by Florida Department of Environmental Protection Table 2-1 is a summary of private sector water systems operating within Collier County, but regulated by the FDEP due to very small capacities. These systems primarily serve individual establishments, such as schools, stores, or golfing communities. The list was developed from the FDEP drinking water database and is accurate as of April 11, 2018. Table 2-1.

Section 4 · Existing Water Supply Facilities 4-2 PW/6295/231366/03/01 4.1.2 Potable Water Facilities 4.1.2.1 Wellfields Currently, the CCWSD operates four wellfields: The Golden Gate Tamiami Wellfield, the North Hawthorn Reverse Osmosis (RO) Wellfield, the South Hawthorn RO Wellfield, and the Northeast Service Area Wellfield (formerly the OTUC Wellfield). The location of each of these wellfields is illustrated in Figure 4-1. The North Hawthorn RO and South Hawthorn RO wellfields contain wells that tap the Hawthorn Zone 1 (HZ1) and the Lower Hawthorn (LH) aquifers, both of which are brackish in those areas of Collier County. The wellfields provide raw water for the low- pressure reverse osmosis (LPRO) treatment trains at the North County Regional Water Treatment Plant (NCRWTP) and the South County Regional Water Treatment Plant (SCRWTP), respectively. The Golden Gate Tamiami Wellfield contains wells that tap the LT Aquifer, which contains freshwater. This wellfield provides raw water for the membrane filtration (MF) equipment at the NCRWTP and the lime softening (LS) equipment at the SCRWTP. The Orange Tree Water Treatment Plant (OTWTP) is located east of SR-846 and north of CR-858. The OTWTP was integrated into the Collier County Water-Sewer District in March of 2017 and has a constructed treatment capacity of 0.75 MGD using membrane softening (MS) and its wells also tap the fresh LT Aquifer. Tables 4-2, 4-3, 4-4, and 4-5 and summarize the existing wells in the Golden Gate Tamiami Wellfield, the Orange Tree Wellfield, the North Hawthorn RO Wellfield, and the South Hawthorn RO Wellfield, respectively. 4.1.2.2. Water Treatment Facilities The CCWSD is served by three water treatment plants (WTPs), the NCRWTP, the SCRWTP, and the OTWTP which are shown in Figure 4-2. The NCRWTP is located on the north side of Vanderbilt Beach Road Extension east of CR-951 in the northeastern quadrant of the service area. The plant utilizes groundwater withdrawn from the LT, HZ1 and LH aquifers. Water from the LT Aquifer is treated using MF, while water from the HZ1 and LH aquifers is treated by LPRO. Currently, the plant is capable of producing 20 MGD of finished water; 12 MGD from the MF process and 8 MGD from the LPRO process. The SCRWTP is located near the intersection of CR-951 and I-75 about 5.5 miles south of the NCRWTP. The plant utilizes groundwater withdrawn from the LT, HZ1 and LH aquifers. Water from the LT Aquifer is treated using LS, while water from the HZ1 and LH aquifers is treated by LPRO. Currently, the plant is capable of producing 32 MGD of finished water; 12 MGD from the LS process and 20 MGD from the LPRO process. The OTWTP is located east of SR-846 and north of CR-858. The wells maintained by OTUC tap the LT Aquifer, which is a traditional freshwater source. The WTP has a finished water capacity of 0.75 MGD using membrane softening (MS). A summary of the existing water treatment facilities is provided in Table 4-6. In addition to identifying the design capacity of each treatment train, the amount of raw water required to achieve the design capacity is also provided.

It is calculated by multiplying the Required Treatment Capacity @ 150 gpcd by the Raw to Finished Water Adjustment. 4.1.2.3 Pumping, Storage, and Transmission The existing transmission facilities consist of transmission pipelines, water storage tanks, an ASR system, and pumping facilities. The storage and pumping facilities utilized by CCWSD are shown in Figure 4-3. The pumping facilities are comprised of high service pumps located at both water treatment plants, four water booster pumping stations and an in-line booster pump station. Ground storage tanks at the treatment facilities and at the booster pumping stations provide system storage and reserve capacity to help meet the peak hourly demands of the system. The booster pumping stations and storage tanks are located at the Isle of Capri, Manatee Road, and Carica Road. The CCWSD also maintains and operates the Goodland Water Booster Pumping Station, which is part of the Goodland Water Sub-District. An in-line booster station is located in the northwest portion of the system near Vanderbilt Drive. In addition to the traditional storage and pumping facilities mentioned above, CCWSD maintains a 1 MGD potable water ASR system at the Manatee Road Pumping Station. The water storage tank at the OTWTP has a capacity of 0.75 MG and the transmission pipelines range in size from 3-inch to 12-inch and total approximately 9 miles in length. As previously mentioned, the CCWSD acquired the Golden Gate City potable water and wastewater utility systems from FGUA on March 1, 2018 acquiring their storage and booster pump station tanks. Potable water is stored at various strategic points in the CCWSD distribution system to help meet diurnal peak system and fire flow demands. A summary of the existing storage facilities is provided in Table 4-7. Potable water is pumped from the plants into the distribution system. The distribution system includes water mains designated as either transmission or distribution mains. The CCWSD pipelines 16 inches in diameter and larger are generally termed transmission mains. These are typically located along arterial and collector roadways and convey water to major demand areas. Pipelines that are smaller than 16 inches in diameter are generally called distribution mains, branching off to the transmission system to supply individual users. + ++ + + + + + + + ")951 BONITA BEACH R D I M M O K A L E E R D GOODLETTE FRANK RDTAMIAMI TRAIL ")858 Golden Gate WTP Tank Green Blvd Booster Pump Station Tank OTWTP §¨¦75 §¨¦75 £¤41 UV45 ")92 £¤41 £¤41 ")846 UV84 ")951 UV93 NCRWTP SCRWTP MANATEE ROAD ASR CARICA BOOSTER STATION MANATEE BOOSTER STATION GOOD LAN D BOOSTER STATION ISLE OF CAPRI BOOSTER STATION Service Layer Credits: Esri, HERE, Garmin, © OpenStreetMap contributors, and the GIS user community - 9/26/2018 ¯0 1 2 3 4 Miles FIGURE 4-3COLLIER COUNTY 10-YEAR WATER SUPPLY FACILITIES WORK PLANEXISTING CCWSD POTABLE WATER STOR AGE FAC ILITIES Legend +Existing P otable Water Storage Facility Potable Water Main (>= 12") Section 4 · Existing Water Supply Facilities 4-11 PW/6295/231366/03/01 Table 4-7.

There are a few small interconnects between the two service areas, but the system is hydraulically limited from passing large volumes of water from one service area to the other. A design has been completed for pump station improvements that will enhance the County’s ability to transfer flows between the north and south service areas. Reclaimed water produced at the two WRFs can be temporarily stored in on-site ponds. Storage of up to 1 million gallons (MG) is also available at the former Pelican Bay WRF, which was decommissioned in 2006 and converted to a reclaimed water storage and pumping facility. Additional storage is achieved in the distribution system which provides 130 MG of wet weather storage. Excess water is pumped into deep injection wells (DIWs) for disposal. Figure 4-6 presents the reclaimed water distribution system. The County owns and maintains a hydraulic model of its IQ water distribution system that enables it to plan for orderly expansion and development of its system. One of the significant challenges that the reclaimed water system faces is wet weather storage. During the wet season, demand for reclaimed water drops off sharply and CCWSD is forced to discharge the reclaimed water into its deep injection wells (DIW) disposal. The County has identified this scenario as a waste of a valuable resource and is making efforts to reduce the amount of reclaimed water that is discharged into DIWs during the wet season. To this end, a reclaimed water/supplemental groundwater aquifer storage and recovery (ASR) system has been developed. The system currently includes two constructed ASR wells, the latter of which was completed in 2015 and is currently undergoing cycle testing. Following the cycle testing, the ASR well will be put into regular service, where it is expected to provide between 0.5 and 1 MGD of IQ water to meet peak season demands. With both wells operational, they are expected to provide between 1 and 2 MGD of storage and recovery capacity to assist with meeting peak season demands. The plan for ultimate buildout at this ASR site in the north part of the County is to have five ASR wells with a total withdrawal capacity of up to 5 MGD. The County has also explored the feasibility of an additional ASR site in the southern portion of its IQ water distribution system. 4.1.3.3 Supplemental Wellfields In addition to the two existing WRFs pumping and storage facilities, CCWSD utilizes two supplemental wellfields to meet its contractual requirements. The locations of the two wellfields, known as the Pelican Bay (Livingston Road) Wellfield and the Immokalee (Mule Pen Quarry) Wellfield, are shown in Figure 4-6. The wellfields are permitted under CUP 11-00052-W, described in Section 4.1.1, which allows CCWSD to withdraw water from the LT Aquifer in the Pelican Bay Wellfield and the WT Aquifer at the Immokalee Wellfield, to meet peak demands within the reclaimed water distribution system.

Starting in the mid-1980s CCWSD realized that it could not meet the future demands of its customers solely with traditional water supplies. CCWSD committed to a program of alternative water supplies that included the use of brackish groundwater and ASR for potable supply, and reclaimed water, supplemental water wellfields and ASR for storage and increased use of irrigation quality water for irrigation purposes. Given the success that CCWSD has had in meeting its demands with alternative water supplies, CCWSD embarked to identify better ways to meet future water supply demands within its service area. The result of this effort is a paradigm shift, from thinking of potable water and irrigation water demand as two separate needs to seeing the demands as inextricably intertwined. To better serve the needs of both potable water and irrigation water demand at the best value cost for the customer, CCWSD has begun development of a new business model which will shift the focus from development of additional potable water supplies to meeting a large portion of the overall water demand with irrigation quality water supplies. CCWSD currently has an annual average daily potable demand of 28.69 MGD and an annual average daily irrigation quality demand of 23.0 MGD. The ratio of irrigation quality demand to potable demand is approximately 45:55. As stated in Section 4.1.3 there is an additional 28.5 MGD of irrigation quality demand in the service area from entities that have installed dual distribution piping. The vision for CCWSD is optimizing water resource usage by substituting IQ water for non-potable uses such as irrigation, which will provide both economic and environmental benefits. Through implementation of the vision, it is anticipated that within the next 20 years the source of water can shift from 45 percent IQ water and 55 percent potable water to 60 percent IQ water and 40 percent potable water. Since the 2014 10-Year Water Supply Facilities Work Plan Update, the CCWSD has shifted the ratio from 40:60 to 45:55. This shift will occur as supplemental water supplies, and ASR storage components are added to the IQ water system and utilized to supply IQ water to customers, reserving higher quality water supplies for true potable use. It is anticipated that a portion of future potable water demand will be offset by substituting IQ water for potable water currently being used for irrigation. As a result of meeting irrigation demands with IQ water, 90 percent instead of 70 percent of potable water delivered to customers will be returned to the water reclamation facilities to be reused. In addition to meeting irrigation demands, the focus on additional IQ water supplies instead of only potable water supplies provides significant benefits to the environment. By supplying IQ water to more customers, the use of potable water for irrigation and private irrigation systems will decrease. Further, the CCWSD IQ water distribution system often provides for a better temporal distribution of water to the natural system in that IQ water is provided at low rates over longer periods than typical rainfall events and is supplied during low rain periods when the Section 5 · Planned Water Supply Facilities 5-2 PW/6295/231366/03/01 aquifer system is most able to accommodate recharge thereby reducing runoff. Additionally, CCWSD’s IQ water distribution system provides a net addition of freshwater to the surficial aquifer system through irrigation with treated water from the brackish Hawthorn aquifer system, which is otherwise trapped in very long-term and deep hydrologic cycles, bringing it into the daily water cycle. In order to supply additional irrigation water more efficiently, CCWSD will pursue additional allocations of fresh water. This strategy is supported by recently identified groundwater trends. Through its rigorous groundwater monitoring program, CCWSD identified trends in water level data from both the Lower Tamiami (LT) Aquifer and the Water Table (WT) Aquifer (connected to surface water flows, i.e., wetlands) in and around the CCWSD’s Golden Gate Tamiami Wellfield. The data indicate that despite extended drought conditions and increased pumping from the LT Aquifer, water levels in key indicator wells are remaining steady and in some cases increasing. These trends provide evidence that the total water management approach taken by the CCWSD is yielding environmental benefits and suggest that additional pumping of the LT Aquifer is possible without impacting the WT Aquifer or wetlands, which is the main concern that directed CCWSD away from traditional sources more than twenty years ago. CCWSD’s intent to pursue additional freshwater withdrawals from the LT Aquifer within the integrated total water management approach is consistent with the 2017 Lower West Coast Water Supply Plan Update (LWCWSP) published by the SFWMD, which states on page 89, “While the development of fresh groundwater in many areas of the LWC Planning Area has been maximized, it may be available in some places. As urban growth occurs, some agricultural land is expected to transition to urban community uses. Many existing agricultural areas have water use permits to use fresh groundwater for crop irrigation. While water use permits cannot be directly transferred from one land use type to another, conversion of agricultural lands to another use may result in available fresh ground water” Likewise, on page 90, “Additional limited supplies may be developed and permitted from the SAS and IAS depending on local resource conditions, changing land use, and the viability of other supply options.” In addition to the water level trends observed in its monitoring wells, CCWSD has performed and is performing multiple studies to determine the viability of the LT Aquifer for additional allocations. To date, CCWSD has developed a calibrated groundwater model and utilized the MIKESHE model developed by the Army Corp of Engineers for the Picayune Strand Restoration Project to determine the potential impact of additional freshwater withdrawals on wetlands. The modeling efforts performed to date indicate that there would be no measurable impact on wetlands from moderate additional withdrawals. CCWSD has also constructed freshwater monitoring well clusters around the County that will provide longer term water level data for areas of the County away from its wellfields and developed four wetland monitoring sites within the Golden Gate Estates to verify that no wetland impacts are being caused by withdrawals from the Golden Gate Tamiami Wellfield. CCWSD is confident that the modeling efforts performed to date, and its on-going water level monitoring program, will provide the required assurances to allow the SFWMD to increase its permitted allocation of freshwater from the LT Aquifer. CCWSD will develop documentation demonstrating how existing and planned IQ water supplies give rise to additional potable water supplies. This analysis will consider the potential availability of impact offsets and substitution credits in accordance with new Florida Department of Environmental Protection and SFWMD Section 5 · Planned Water Supply Facilities 5-3 PW/6295/231366/03/01 rules. CCWSD anticipates that its planned IQ water infrastructure development will garner significant impact offsets and/or substitution credits in further support of its request to the SFWMD for additional allocations of freshwater to meet projected customer demand. These water resource benefits and associated availability of withdrawals will be in addition to the benefits already provided by CCWSD’s existing IQ water system. For these reasons, CCWSD has initiated the shift in its business model based on an ability to obtain a reasonable amount of freshwater to maximize the efficiency of existing infrastructure and planned AWS projects. 5.1.1 Potable Water Facilities 5.1.1.1 Wellfields As part of the CCWSD plan to meet future water supply needs it intends to build the NERWTP Wellfield Phase 1. The NERWTP Wellfield Phase 1 will be made up of wells tapping the LT Aquifer, the HZ1 Aquifer and the LH Aquifer. The wells will serve the NERWTP Phase 1, which will treat the water using ion exchange (IE) for fresh water and LPRO for brackish water. The wellfield is scheduled to come online in 2027 to serve the first phase of the NERWTP. Table 5-1 summarizes the planned wells in the NERWTP Wellfield Phase 1. Table 5-1.

The distribution system includes water mains designated as either transmission or distribution mains. The CCWSD pipelines 16 inches in diameter and larger are generally termed transmission mains. These are typically located along arterial and collector roadways and convey water to major demand areas. Pipelines smaller than 16 inches in diameter are generally called distribution mains, branching off the transmission system to supply individual users. Overall, the CCWSD owns and maintains over 1,000 miles of water transmission and distribution pipelines, up to 48 inches in diameter, with over 56,000 individual service connections. With the construction of 5 MGD of additional finished water capacity, CCWSD will be installing a substantial number of transmission mains and major distribution mains over the next 10 years. The existing and planned transmission mains and major distribution mains that will serve CCWSD in 2028 are illustrated in Figure 5-4.

The majority of the existing customer base includes golf courses, residential communities, environmental mitigation areas, county parks, and roadway medians. There is an additional demand of 28.5 MGD in the service area from entities that have installed dual distribution piping. The following subsections describe the measures CCWSD is taking to meet future wastewater demands and supply reclaimed water to its customers. 5.1.2.1 Water Reclamation Facilities The locations of the existing NCWRF and SCWRF are shown in Figure 5-5. There are plans to proceed with NEWRF Phase 1. Table 5-7 summarizes the capacities of the existing and planned WRFs. Table 5-7.

The amount of reclaimed water available is based on influent flow and treatment efficiency. For planning purposes, CCWSD considers reclaimed water availability based on 95 percent of the minimum monthly effluent flow. As stated in the footnotes to Table 5-7, the amount of reclaimed water distributed is not directly related to the design capacity of each water reclamation facility. In addition to the limitations identified, the ability of CCWSD to utilize available reclaimed water for distribution is impacted by seasonal fluctuations in demand, with very high demands during the dry season and low demands during the wet season. Table 5-8 identifies the major tasks required to build the NEWRF, along with the funding source that will be utilized and the scheduled dates for studies, property acquisition, design, permitting, and construction.

There are a few small interconnects between the two service areas, but the system is hydraulically limited from passing large volumes of water from one service area to the other. As additional reclaimed water becomes available through population growth and increased wastewater flows, and once existing demand is met, CCWSD will need to expand the reclaimed water distribution system to serve more customers. At this time, specific distribution and transmission main projects have not been determined. Temporary reclaimed water storage is available on-site at the WRFs. Additional storage will be provided through the expansion of the existing reclaimed water ASR from a capacity of 2 MGD to 5 MGD.

It is calculated by multiplying the Required Treatment Capacity @ 150 gpcd by the Raw to Finished Water Adjustment. 4 CCWSD has two potable water supply consumptive use permits. CUP 11-00249-W allocation is for 55.53 MGD annual average and expires on September 22, 2036. CUP allocation 11-00419-W is for 0.65 MGD and expires on March 7, 2023. 5 CCWSD is proactive in renewing its CUPs in advance of expiration and intends to maintain the necessary CUPs to meet the raw water requirement. 6 Calculated by subtracting the Raw Water Requirement from the Permitted Amount. Section 6 · Facilities Capacity Analysis 6-2 PW/6295/231366/03/01 As will be noted from Table 6-1, the allocation under CCWSD’s current CUP (11-00249-W) is sufficient to meet the raw water requirement needed to make the Required Treatment Capacity at 150 gpcd through 2028. 6.1.1 Concurrency Analysis Each year, the Public Utilities Division completes a concurrency review of its “Category A” facilities, including potable water. The analysis becomes a part of the Countywide Annual Update and Inventory Report (AUIR). Although concurrency is mandated through state and local law for a two year period, the AUIR analysis goes well beyond 10 years. Like the AUIR, the CCWSD uses an additional tool to assure concurrency. Known as “Checkbook Concurrency,” the tool is used quarterly to update capacity projections. While the AUIR relies on BEBR population estimates for future growth, the Checkbook tracks approved development (Planned Unit Developments and Developments of Regional Impact) as an additional measure of future capacity. It also measures 3-day peak demand rather than seasonal demand. The CCWSD Water and Wastewater Master Plans are the primary planning tools for capital planning. Nevertheless, the AUIR and Checkbook concurrency measurements serve as additional safeguards to assure future capacity. 6.2 Immokalee Water and Sewer District (IWSD) Table 6-2 shows the capacity analysis for IWSD for the 10-year planning period. The improvements planned by the IWSD for the 10-year planning period are sufficient to meet the demands of the service area and the allocation of the underlying CUP (11-00013-W) is sufficient to cover the withdrawals required to make the finished water demand. Table 6-2.

It is calculated by multiplying the Annual Average Daily Demand by the Raw-To-Finished -Water Adjustment. 5 CUP (11-00013-W) allocation is 4.15 MGD annual average and expires on May 23, 2031. 6 Calculated by subtracting the Raw Water Requirement from the Permitted Amount. Section 6 · Facilities Capacity Analysis 6-3 PW/6295/231366/03/01 6.3 Ave Maria Utility Company, LLLP (AMUC) Table 6-3 shows the capacity analysis for AMUC for the 10-year planning period. Based on the capacity analysis, AMUC does not have sufficient permitted capacity to meet the demands of its service area for the 10-year planning period. The allocation of the underlying CUP (11-02298-W) only convers the withdrawals required to make the finished water demand until 2025. After 2025, the Permitted Surplus (Deficit) becomes negative. AMUC will need to increase their permitted consumptive use by 2025. Table 6-3.

The following subsections outline the conservation regulations and practices utilized by each of the utilities covered under this plan. The information provided has been taken directly from the water conservation plans approved by the SFWMD and included in each utility’s consumptive use permit. 7.1 Collier County Water-Sewer District (CCWSD) The conservation plan implemented by CCWSD is described in the utility’s consumptive use permit as follows: The Collier County Board of Commissioners enacted Ordinance 2002-17, which reduced watering to three days per week (three times each for odd and even numbered addresses), in an effort to reduce water consumption. This ordinance also requires that rain sensor devices be installed on automatic irrigation systems. The Board initiated an ASR program to allow for the storage of excess water that can later be withdrawn to offset peak usage. Other water conservation measures designated by the SFWMD, which Collier County has enacted include: Requiring low flow plumbing fixtures as part of the Land Development Code (LDC); Encouraging the use of Florida Friendly landscapes and other drought-tolerant vegetation in portions of the LDC; Implementing water conservation rates that increase per-thousand gallon charges as usage increases; Monthly reading of all customers’ meters to minimize losses from unaccounted-for water; An active reuse program, which delivers over 4.5 billion gallons a year of reclaimed wastewater, to reduce irrigation withdrawals; Filter backwashing at the SCRWTP to eliminate water lost in cleaning filters; and Enacted in 2003 to further promote water conservation, the Board approved a mandatory water high-consumption surcharge, which is applied when the SFWMD implements water restrictions and impacts on only high-use consumers. In addition to these water conservation measures, the CCWSD and other County agencies endeavor to educate the public regarding water conservation through educational and outreach programs. Staff members routinely conduct presentations for schools, civic groups, homeowner associations, and other receptive groups. Division staff participates in events, such as “Senior Section 7 · Conservation Regulations and Practices 7-2 PW/6295/231366/03/01 Expo” and “Government Days,” to take the water conservation campaign to the public. Utility bill inserts and advertising have further helped to spread the message. The County has actively been promoting the “Fridays are Dry Days” campaign, which has become the tag line on commercials airing on radio stations throughout Collier County. These stations were selected to target a large number of consumers, including those who do not speak English. The tag line has also been utilized in several productions airing on the Collier County Government Channel. Public service announcements and specially produced videos promoting water conservation also air on the County’s government access television station, Channel 11/16. CCWSD has made significant strides towards improving and enhancing the efficiency of the Water Distribution System and aims to continue to do so over the next 10 years. Maintaining an efficient system with upgraded and preventive maintenance efforts keeps unplanned water losses to a minimum. CCWSD’s average unaccounted-for water is currently below 10 percent, according to the unaccounted water loss report submitted to the SFWMD. Traditionally, water loss in Collier County Water District has remained low due to aggressive water loss management practices. Figure 7-1 shows the unaccounted-for water loss over the past 15 fiscal years. As indicated in Figure 7-1, the CCWSD unaccounted-for water loss has lowered during the recent 10 years (period between 2008 to 2017) when compared to its preceding period. Figure 7-1 CCWSD Unaccounted-for Water Loss from FY2002 to FY20171 1 The CCWSD Unaccounted-for Water Loss from FY2002 to FY2013 was taken from the previous 2013 10-Year Water Supply Plan Update. Specific projects the CCWSD has or will undertake to further water conservation include: Ongoing effort to replace valves that are reaching the end of their useful life and to install and additional (20) valves per year to assist with increase responsiveness to system events. Mapping new areas incorporated into the district, including Golden Gate City, and North East Service Area (i.e. Orange Tree Utility). 9.7% 8.4%8.5% 11.5% 10.0% 12.2% 4.5% 3.3%4.0% 4.9% 3.1% 4.6% 3.8%4.0% 5.4% 9.3% 0.0% 2.5% 5.0% 7.5% 10.0% 12.5% 15.0%2002200320042005200620072008200920102011201220132014201520162017Percentage of Unaccounted-for Water LossFiscal Year Section 7 · Conservation and Practices 7-3 PW/6295/231366/03/01 On-going effort to replace lead service lines that are traditionally a major portion of the water loss for the CCWSD. Considering the age of the service lines, CCWSD’s goal is to replace up to 75 service lines per year. Continue with the meter change-out program for the replacement of all ¾” to 2” potable meters. Of the over 56,000 meters originally identified by CCWSD, approximately 7,500 meters are left to replace. The meter change-out program is scheduled for completion by September 30, 2019. On-going activity of replacing water mains utilizing a “just in time” method methodology of replacement. Mains are replaced after several failures versus waiting until they become an operational issue. This improves service reliability and fire protection capacity and reduces the potential for water loss. Changes to the Utility Standards Ordinance now require developers of new areas to provide flushing stations for areas that may have concerns with maintaining sufficient residual. This results in the reduction of overall water loss due to required flushing to maintain disinfectant residuals. Collier County is actively completing water looping projects. Looping is promoted by imposing and tracking PUD commitments and through enforcement of design criteria which require all new potable water distribution systems to be looped. Looping conserves water by eliminating dead ends, which must be flushed to maintain minimum chloramine residuals. · Collier County’s projects that have been completed over the past five years are: o Wilshire Lakes, o Treefarm Road, o Twin Eagles, o Heritage Bay, o Waterways Boulevard, and o Orange Tree Boulevard. · The water looping projects planned over the next five years include: o Wildflower Way, o Warren Street, o Quarry/Esplanade, o Saturnia Lakes, and o Bergamot Lane. Section 7 · Conservation Regulations and Practices 7-4 PW/6295/231366/03/01 Collier County Water District is proactively acquiring older utilities, such as Golden Gate City. This allows for sharing of water resources among a larger number of customers and enhanced maintenance, which will decrease unaccounted for water levels in these areas. Employing other contractual resources to perform leak detection for older areas of the Water District. 7.2 Immokalee Water and Sewer District (IWSD) The conservation plan implemented by IWSD is described in the utility’s consumptive use permit as follows: Pursuant to the SFWMD Applicants Handbook for Water Use Permit Applications (September 2015), Section 2.3.2 F. 1. Water Conservation Requirements, all public water supply utilities are required to develop and implement a water conservation plan. Each of the mandatory water conservation elements must exist or have a proposed time frame for implementation. As mentioned earlier, the IWSD was established under Florida law and has specific duties and quasi- governmental rights. However, the authority to enact ordinances does not reside with that District. The applicant has stated they will request that Immokalee enact any required ordinances within a year of permit issuance. The applicant has provided the following water conservation plan elements: A. Permanent Irrigation Ordinance: An ordinance which restricts landscape irrigation to the hours of 4:00 p.m. to 10:00 a.m., 7 days per week, is currently not in effect for the service area. The utility will request that Immokalee adopt an ordinance for the service area within 1 year of permit issuance. B. Xeriscape Ordinance: An ordinance which requires the use of xeriscape landscape principles is currently not in effect. The utility will request that Immokalee adopt an ordinance for the service area within 1 year of permit issuance. C. Ultra-Low Volume Plumbing Fixture Ordinance: An ordinance which requires ultra- low volume plumbing fixtures on all new construction is in effect for the service area. D. Water Conservation Rate Structure: The applicant has a conservation-based rate structure, which includes increasing block rates as a means of reducing demands. E. Leak Detection Program: The applicant does not have an unaccounted-for water and leak detection program because the unaccounted-for water losses are less than 10 percent. F. Rain Sensor Device Ordinance: An ordinance which requires any person who purchases and installs an automatic lawn sprinkler system to install, operate, and maintain a rain sensor device or automatic switch which will override the irrigation system with the occurrence of adequate rainfall is currently not in effect for the service area. The utility will request that Immokalee adopt an ordinance within 1 year of the permit issuance. Section 7 · Conservation and Practices 7-5 PW/6295/231366/03/01 G. Water Conservation Education Program: The applicant distributes pamphlets, makes school visits, and provides information booths for employees and customers. Information signs, press releases, and messages about water conservation on the bills are also utilized. H. Reclaimed Water: Currently, all wastewater effluent is disposed of via a spray irrigation field and percolation ponds. 7.3 Ave Maria Utility Company, LLLP (AMUC) The conservation plan implemented by AMUC is described in the utility’s consumptive use permit as follows: Per Section 2.3.2 F of the SFWMD Applicants Handbook for Water Use Permit Applications, public water supply in excess of 500,000 gpd requires a water conservation plan addressing the following conservation elements: Permanent Irrigation Ordinance, Xeriscape Ordinance, Ultra- Low Volume Plumbing Fixture Ordinance, Water Conservation Rate Structure, Leak Detection Program, Rain Sensor Device Ordinance, Water Conservation Education Program, and Reclaimed Water Use. The following information is provided. A. Permanent Irrigation Ordinance: One of the water conservation efforts the Ave Maria University and Town will pursue is adoption of an irrigation ordinance to limit irrigation water usage during the dry season. The planned ordinance would follow watering restrictions adopted by Collier County, including limiting daytime watering times and limiting the number of days that lawns could be watered. The irrigation ordinance would also likely follow an even/odd address watering system. B. Xeriscape Landscape Ordinance: The University and Town of Ave Maria will pursue adoption of an ordinance which recommends the use of xeriscape principles in landscape planning for all new construction. The ordinance would encourage implementation of xeriscape landscaping practices including use of mulches, native and drought tolerant plants, and limited turf areas. C. Ultra-Low Volume Plumbing Standards: The university and town of Ave Maria will pursue adopting an ordinance requiring ultra-low volume plumbing fixtures in all new construction. The standards proposed in the planned Ave Maria Plumbing Code would, in most cases, be as stringent as the ultra-low plumbing standards stipulated in the SFWMD Water Conservation Plan Development Guidelines. D. Water Conservation Rate Structure: The Town of Ave Maria plans to utilize an inclining block rate structure in order to promote water conservation. Residential and commercial water rates will consist of a monthly capacity cost charge (base rate) and a monthly commodity costs charge (volume charge). The commodity costs charges will increase with increased volume use. For example, residential costs increase from $1.75 per thousand gallons for under 5,000 gallons, to $4.00 per thousand gallons for quantities over 30,000 gallons. The details and the planned water rate schedule have not been specifically determined yet. Section 7 · Conservation Regulations and Practices 7-6 PW/6295/231366/03/01 E. Leak Detection & Distribution System Losses Program: A leak detection program will be implemented by the AMUC if system losses exceed 10 percent. The leak detection program will likely utilize the Rural Water Association (RWA) sonic type leak detection equipment. System losses may be attributable to known line breaks. The Ave Maria Utilities Department will repair water main and service line breaks as soon as possible to minimize and prevent distribution system losses. F. Sprinkler System Rain Sensor: The Town of Ave Maria will recommend installation of rain sensor devices on automatic lawn sprinkler systems for all new construction. G. Public Education Programs: The AMUC will pursue public education programs on water conservation and community responsibility. The programs could include presentations by Utility staff, such as water conservation topics discussed during tours conducted at its facilities. H. Water Treatment Plant and Waste Water Reclamation Facility. Educational brochures on water conservation, landscaping and xeriscape can be distributed by the Utility offices. The AMUC could also include water conservation information to all customers along with monthly billing statements. I. Reclaimed Water: The most important element of Ave Maria’s Water Conservation Plan is utilization of a reclaimed water system for irrigation. The Town and University will pursue the use of as much reclaimed water as possible and will likely be able to utilize 100 percent of the reclaimed water generated. 8-1 PW/6295/231366/03/01 Section 8 Capital Improvement Projects Section 5 of this plan focused on the projects that each of the utilities have planned for the 10- year planning period. Attention was paid to the amount of water made available and when it would be made available. The following subsections present the capital improvement projects planned by each utility, including the funding source, project number, project name, and cost estimate for each project. 8.1 Collier County Water-Sewer District (CCWSD) The most recent lists of CCWSD water and wastewater capital improvement projects were developed as part of the Fiscal Year 2017 Water and Wastewater User Rate Study. The capital improvement projects pertinent to future water supply are summarized in Table 8-1. CCWSD funds its water and wastewater projects from four funds: 411 – Water Impact Fees, 412 – Water User Fees, 413 – Wastewater Impact Fees, and 414-Wastewater User Fees. Impact fees are utilized to pay for expanded supply projects, while user fees are used to fund operations, maintenance, and replacement of existing facilities. 8.2 Immokalee Water and Sewer District (IWSD) The most recent lists of IWSD water and wastewater capital improvement projects were developed as part of the Fiscal Year 2018 Water and Wastewater Utility Rate Study. The capital improvement projects pertinent to future water supply are summarized in Table 8-2. IWSD funds its water and wastewater projects from Seven funds: USDA Water Grant Funds, USDA Water Loan Funds, USDA Wastewater Grant to be obtained, USDA Wastewater Loan to be obtained, Rate Revenue – Sewer (RRS), Rate Revenue – Water (RRW), and funds to be determined at a later date (TBD). 8.3 Ave Maria Utility Company (AMUC) AMUC is currently in the process of updating their CIP and is unable to provide reliable information at the time of writing this report (October 2018). The capital improvement projects for AMUC future water supply that were provided in the 2018 LWCWSP are summarized in Table 8-3.

Faulkner Corrected version of Resolution will be uploaded to Accela. [Done] 22:15 Fryer Reference to the termination of the Potable Water Bulk Services Agreement with Marco Island for Marco Shores 22:50 Klatzkow Explained situation and offered his opinion that the City of Marco Island is not legally entitled to reimbursement of impact fees; will be a BCC decision 25:45 Fry New (NE) Water Treatment Plant online around 2025; looks like it is out north of Immokalee, way out there. Why was that location chosen so far away from population growth? 26:12 Fry Capacity deficit for Ave Maria Utility Company--didn’t notice a solution for the deficit in the plan. Is that solution included in the plan? 26:46 Fey AMUC capacity deficit—AMUC is identified in the Lower West Coast Water Supply Plan as one of two utilities that need to perform water supply projects to meet projected demand. A 2.5 MGD capacity WTP is included in the LWCWSP to address the deficit. (Additional comments provided by Jason Sciandra at 46:37.) 27:47 Fey NE WTP location—facility is centrally located within the NE Service Area; 3 of 4 large developments actively pursuing zoning; fourth already held a pre- application meeting. Strain The four developments include Hogan Island (pre-app), Hyde Park, Rural Lands West, and Immokalee Rural Village. The new WTP is in the north part of Orange Tree. Immokalee has its own utility service. 29:11 Schmidt Does Plan include any changes to the wellfield protection areas identified in the Comp Plan? 29:21 Fey No, Pollution Control is working on an update to the Ordinance separately. 29:37 Strain The map on page 7 of the staff report identifies the 2018 AUIR; relabel this map or change map to the one used in 2018 AUIR. Areas in blue are not the same. 31:24 Fey The map in the staff report is the updated map and includes the service area resulting from BCC action on September 11, 2018 that expanded the district boundaries. It was not included in the 2018 AUIR because the AUIR was prepared prior to this action. [Update: Reference to the 2018 AUIR was deleted from the map on page 7 of the staff report.] 33:15 Strain Design Treatment Capacity (Table ES-1) doesn’t match with the Available Facility Capacity (Table ES-2), which doesn’t match with the numbers in the AUIR (New Treatment Capacity, Page 51 in the AUIR). You don’t reference Design Treatment Capacity in the AUIR. [See Fey, 48:28.] 33:46 Strain Page ES-3 (Table ES-2), the Service Population, Required Treatment Capacity, Available Facilities Capacity, Facility Capacity Surplus, Permitted Amount, and Permitted Surplus numbers don’t correspond with the 2018 AUIR. Example: 2018 Population—AUIR 186,362; WSFWP 241,422. Why wouldn’t you use the AUIR numbers that have already been vetted and approved by the BCC? 35:14 Fey The WSFWP uses peak season population while the AUIR uses permanent population. 35:31 Strain Wouldn’t that generate a higher number in this document? 17.A.4 Packet Pg. 1794 Attachment: Attachment A - CCPC Questions and Answers (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Attachment A Time Speaker Comments/Questions 35:38 Fey The AUIR addresses WTP capacity based on max. 3-day demand, which has a higher multiplier than peak season. Consumptive use permits issued by the SFWMD are based upon max. month. Peak season population is being used in this document to be consistent with the LWCWSP. [Correction: The LWCWSP uses permanent population.] 36:15 Strain If this is supposed to be based on the AUIR, why don’t you use the same numbers and the same terminology in this document? 37:22 Fey We will work to provide consistency and explanations as to why the numbers differ. [See action item #1 below.] 38:09 Strain Figure 2-1—Why is Marco Shores area not colored? Who serves that area? 38:59 Fey We currently serve Marco Shores via bulk water master meter on CR-951; Marco Island is terminating agreement and will supply water to Marco Shores upon completion of a new water main extension. 39:30 Strain Won’t Marco Island serve Marco Shores within the 10-year planning horizon? 39:44 Fey Yes, the water main extension should be complete within a matter of months. 39:49 Strain Then Marco Shores should be shown as part of the City of Marco Island’s service area. [See action item #2 below.] Why doesn’t Figure 2-2 show any pipes in Marco Shores? 40:08 Fey The internal piping network is already owned and maintained by the City of Marco Island. 40:33 Strain As previously discussed, the population projections for the CCWSD are inconsistent with the 2018 AUIR. [See action item #1 below.] 41:00 Strain Demand per capita--Immokalee 75, Ave Maria 90, and we’re at 150. Why do we have such a higher demand per capita? 41:27 Fey Per capita use rate is total finished water divided by permanent population and includes commercial, industrial, and institutional uses as well as potable water used for irrigation. These and other factors explain the large differences between urban and rural area water users. [See action item #3 below.] 42:45 Strain What is the City of Naples per capita use rate? 42:48 Fey That information is in the LWCWSP. We will get it for you. [See Fey, 50:25.] 43:06 Chrzanowski What is the typical per capita use rate? Does that include irrigation? Fey 150 gpcd is typical per FDEP, and presumably includes irrigation. Our PCUR has been hovering slightly below 150 (around 140) for the past eight years and will likely continue to decline as irrigation becomes a smaller portion of total demand. [See action item #3 below.] 44:25 Strain Page 5-2--Water levels in the LT Aquifer continue to rise. How often are we collecting data? 45:12 Sciandra We report monthly data to the SFWMD, including monitoring well levels and chloride concentrations. We are getting ready to renew permits. Over time, levels have improved, largely due to shifts in water users—less agricultural and more residential demand. Long-term planning by the County to use alternative supplies has led to more fresh water availability, which is advantageous as treatment is less expensive. 46:37 Sciandra In answer to Fry’s earlier question about deficient supply in the AMUC service area, the additional capacity of the proposed WTP is not included because it is not yet permitted. 17.A.4 Packet Pg. 1795 Attachment: Attachment A - CCPC Questions and Answers (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Attachment A Time Speaker Comments/Questions 47:50 Strain Table 5-3 on page 5-7 shows two facilities for the NERWTP with different capacities. Are you building both? 48:28 Fey Yes, we are building both at the same time. We list them separately because they treat water from different aquifers. 48:36 Strain 2027 is beyond the start dates for the four new communities. How are they going to get water service? 49:18 Fey The regional system has been expanded to include Orange Tree; the regional system has sufficient capacity to serve the initial phases. 49:58 Fry Are the new communities already factored into the population projections? 50:20 Fey That is correct. 50:25 Fey In answer to an earlier question, the City of Naples’ per capita use rate is 207 gpcd. 50:40 Strain Regarding Fry’s question, how would you have factored in the populations of the new developments? 51:55 Fey We have been tracking those developments for years and have build-out schedules from the developers, but we used preliminary results from the Collier Interactive Growth Model. 52:39 Strain Do you have confidence that you used the right persons per household and the right density? 53:13 Fey The CIGM’s numbers were less than developers build-out schedules. For design, we are using developer projections as the worst-case scenario, but the preliminary CIGM results represent the best available information for planning purposes. 53:55 Strain Use of more conservative numbers ensures concurrency. 54:10 Klatzkow The real issue is making sure pipes are sized to handle more people than projected. 54:46 Strain Agreed, that’s why we should be conservative on the plus side. 54:52 Fey We will continue to refine population projections every year through the AUIR, based upon population projections from BEBR and considering growth patterns, as analyzed by Comprehensive Planning. 55:13 Strain Page 6-3, Table 6-3—Ave Maria is growing at a rate of 264 units per year based upon the projection for 2023. Are they really growing that fast? Where do these numbers come from? 55:50 Fey Population figures for Ave Maria are from the LWCWSP, which uses BEBR projections, as refined by the MPO. [Correction: Population figures for 2018, 2023, and 2028 were provided by Jason Vogel of AMUC via email on 9/7/2018, and figures for 2013 were interpolated therefrom.] 56:14 Strain Ave Maria probably could have given you some pretty accurate numbers. 56:25 Fey We can ask them for those numbers; we did coordinate with them on this project. [Done on 9/7/2018] 56:53 Strain Page 7-2, Figure 7-1—Why did water loss almost doubled from 2016 to 2017? 57:40 Fey Acquisition of Orange Tree Utility Company in 2017 may have been a small factor. We will follow up with the Water Division. [See action item #4 below.] 58:28 Strain Page 7-3—Are flushing stations part of the water loss? Are they metered? 58:45 Fey They may account for some of the water loss. They are metered but are not billed. With cul-de-sac development, flushing stations have become prevalent as water main looping is often not feasible on long dead ends. 17.A.4 Packet Pg. 1796 Attachment: Attachment A - CCPC Questions and Answers (7491 : Potable Water Sub element of the Public Facilities Element Amendments) Attachment A Time Speaker Comments/Questions 1:00:00 Strain END OF QUESTIONS ACTION ITEMS: 1 Revise population data for consistency with the 2018 AUIR. 2 The Figure 2.1 map needs to have Marco Shores appropriately shown. 3 Add a discussion of per capita use rate. 4 Add a discussion of water loss, to include an explanation of the increase in 2017. 17.A.4 Packet Pg. 1797 Attachment: Attachment A - CCPC Questions and Answers (7491 : Potable Water Sub element of the Public Facilities Element Amendments) 17.A.5 Packet Pg. 1798 Attachment: BCCCOMPREH-3-2183221_as posted (7491 : Potable Water Sub element of the Public Facilities Element Amendments) 1 FeyEric From:FeyEric Sent:Friday, December 21, 2018 6:57 PM To:'Oblaczynski, Deborah' Cc:Sciandra, Jason; 'Desai, Dharmin D.'; Garcia-Alario, Christina M.; ChmelikTom; MattauschPaul; AbbottAlicia; JohnssenBeth; LibbyPamela Subject:RE: Collier County, Informal Review Comments on the Draft Water Supply Facilities Work Plan Update Attachments:Resolution w_Exhibit A.pdf Importance:High Deb, Thank you for your review of the draft Collier County 10-Year Water Supply Facilities Work Plan.
