Agenda 05/14/2019 Item #17A (Ordinance Amending the the Growth Management Plan)05/14/2019 EXECUTIVE SUMMARY Recommendation to approve an Ordinance 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 adoption amendment to the Florida Department of Economic Opportunity. (Adoption 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 b y Section 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 five 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 163.3177(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 in December 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 demand projections for each utility in the unincorporated area of the County 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. 17.A Packet Pg. 1822 05/14/2019 After the initial transmittal of the GMP Amendment for the Ten-Year Water Supply Facilities Work Plan 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. 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. Section 163.3177(6)(c)3., F.S. provides: 3. Within 18 months after the governing board approves an updated regional water supply plan, the element must incorporate the alternative water supply project or projects selected by the local government from those identified in the regional water supply plan pursuant to s. 373.709(2)(a) or proposed by the local government under s. 373.709(8)(b)….The element must identify such alternative water supply projects and traditional water supply projects and conservation and reuse necessary to meet the water needs identified in s. 373.709(2)(a) within the local government’s jurisdiction and include a work plan, covering at least a 10-year planning period, for building public, private, and regional water supply facilities, including development of alternative water supplies, which are identified in the element as necessary to serve existing and new development…. This GMP amendment is approved as to form and legality. It requires an affirmative vote of four for approval because this is an Adoption hearing of the GMP amendment. [HFAC] FISCAL IMPACT: None GROWTH MANAGEMENT IMPACT: Adoption of the ten-year water supply plan update and subsequent amendment to the Potable Water Sub element of the Growth Management Plan will satisfy the requirements of 163.3177(6)(c), F.S.

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 Update and amendments to the Growth Management Plan (GMP). Under the requirement of the Florida Statutes, the 10-Year Water Supply Facilities Work Plan Update (Plan Update) 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 Update to be included in its city’s comprehensive plan. This 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. 17.A.d Packet Pg. 1844 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - 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 Update.

The information on CCWSD is reflective of the 2014 Water and Wastewater Master Plan Updates, the Collier County 2018 Annual Update and Inventory Report (AUIR) for Public Utilities, and the Collier County Water-Sewer District Fiscal Year 2017-2027 Capital Improvement Plan. The 2018 AUIR and the Fiscal Year 2017-2027 Capital Improvement Plan were approved by the Collier County Board of County Commissioners on November 13, 2018. Based on population projections available for the CCWSD service area, a capacity analysis was performed looking at projected demand versus plant capacity and permitted allocation. The results of the capacity analysis are summarized below in Table ES-2. A discussion of the capacity analysis can be found in Section 6.1. As the capacity analysis illustrates, CCWSD has sufficient existing or planned plant capacity throughout the 2028 planning horizon. Table ES-2.

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 Orange Tree Utility Company (OTUC) was taken over by the CCWSD on March 1, 2017. The CCWSD acquired the Golden Gate City potable water and wastewater utility systems from FGUA on March 1, 2018. 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.

A copy of the most recent version of the interlocal agreement is provided in Appendix A. 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. The CCWSD maintains an interconnection with Marco Shores by which CCWSD supplies potable water on a bulk basis. The City of Marco Island has provided written notification to CCWSD that the Potable Water Bulk Services Water Agreement will be terminated on or around September 26, 2019. [Letter from City of Marco Island to the County attached as Appendix D] The CCWSD 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. 17.A.d Packet Pg. 1855 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 2 · Water Service Areas 2-3 PW/6295/231366/03/01 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. The outlying unincorporated communities served by the City include Plantation Island and Seaboard Village in Copeland. 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. 17.A.d Packet Pg. 1856 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 2 · Water Service Areas 2-4 PW/6295/231366/03/01 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. 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. 17.A.d Packet Pg. 1857 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - §¨¦75 UV93 ")858 UV82 UV951 ")92 ")865 ")850 UV876 UV84 UV29 UV90 UV864 §¨¦75 £¤41 ")846 UV45 £¤41 ")951 UV45 ")846 UV29 UV93 £¤41 05 040106020304050601030205 11 06 01 04 11 08 02 07 02 12 0601 36 03 13 06 09 35 03 07 11 04 11 01 07 32 10 31 05 01 34 08 12 03 05 14 06 10 36 06 02 11 08 1517 10 21 09 12 33 31 11 24 19 11 33 18 11 05 31 36 05 08 04 3432 25 11 11 06 11 11 04 25 11 10 07 30 01 11 14 19 11 11 10 31 18 35 30 13 08 32 33 22 15 09 11 23 22 03 11 36 05 07 11 14 09 15 12 13 27 34 27 34 04 09 34 36 08 11 08 13 11 04 11 04 04 16 03 20 26 11 25 33 05 30 26 12 32 31 16 30 22 11 04 04 33 24 09 17 31 33 19 0103 31 08 15 35 07 05 35 36 09 16 04 19 27 34 28 20 25 06 10 01 30 26 31 32 27 24 34 10 18 36 09 20 21 19 30 08 16 28 06 36 04 13 05 16 11 14 10 23 28 24 33 33 06 35 09 02 31 20 29 12 18 32 28 26 08 18 03 18 03 06 16 28 34 19 17 29 10 02 29 15 2528 06 17 12 11 09 03 35 02 26 19 32 32 14 13 21 0907 07 33 36 07 26 13 17 34 05 22 17 12 33 08 12 28 36 30 32 13 20 1614 21 33 12 13 09 14 25 21 18 06 25 07 33 34 18 15 04 31 36 01 25 09 30 20 21 31 17 07 35 25 21 18 31 31 14 09 19 33 29 32 23 09 23 17 27 15 30 36 05 04 33 32 23 25 26 24 02 18 02 16 02 35 25 18 35 1514 33 22 08 01 13 20 03 14 10 06 29 07 20 25 06 18 32 25 25 02 08 12 24 19 34 32 33 26 31 34 29 01 20 31 27 17 14 16 1416 08 35 08 13 27 15 26 33 35 05 15 19 02 18 28 23 26 13 14 14 23 12 07 02 33 25 15 30 27 06 36 02 07 18 02 17 29 05 01 22 08 29 20 09 30 08 21 22 28 29 27 04 17 21 01 03 07 35 19 08 33 23 16 24 05 10 29 28 35 10 07 25 13 30 35 08 10 12 02 20 13 18 12 04 29 12 13 13 07 16 10 14 28 20 30 16 12 15 24 30 16 01 24 16 21 07 34 32 08 34 12 13 30 20 27 34 26 17 28 13 17 19 04 36 20 14 24 32 08 01 07 36 05 17 08 21 02 14 30 28 24 16 27 23 32 19 34 05 19 16 14 32 30 07 29 14 10 14 05 32 21 12 23 15 12 24 16 21 15 06 25 24 16 22 01 24 26 10 03 01 02 19 12 23 06 26 24 33 25 13 25 12 09 04 01 31 31 02 27 17 29 10 15 29 34 21 26 26 22 32 20 29 1516 29 15 13 24 21 17 06 19 0402 11 18 18 33 09 15 07 29 27 33 30 27 34 23 32 26 13 03 25 22 20 17 29 05 08 23 09 14 20 31 15 27 25 20 20 19 25 12 13 05 32 10 13 30 19 20 01 05 19 23 17 10 01 32 18 09 19 24 23 27 06 22 28 28 19 20 21 16 36 18 03 10 08 29 17 33 19 17 26 23 05 15 12 35 05 14 33 20 18 24 24 17 32 26 21 32 29 22 07 13 28 36 2423 04 04 21 26 16 21 10 04 21 16 34 35 23 08 09 05 26 13 08 28 21 24 22 33 08 32 19 03 35 31 17 28 05 2321 18 06 01 36 24 32 18 28 21 01 25 22 19 22 33 30 04 16 32 20 26 14 35 29 35 14 16 07 12 06 2024 13 22 28 30 09 06 31 28 23 21 05 26 07 23 27 05 31 20 28 34 02 23 22 21 29 24 19 09 06 18 16 04 21 22 07 12 36 10 17 21 09 29 03 12 35 22 20 28 08 10 04 09 35 04 16 21 03 16 06 35 06 03 02 31 19 27 20 36 01 30 36 18 20 28 21 27 06 08 30 21 16 05 22 24 31 28 06 04 18 29 31 10 36 29 17 01 30 08 12 06 34 31 07 07 31 16 07 23 15 02 21 02 28 09 28 09 34 07 26 32 09 15 22 18 04 03 25 08 24 09 09 09 03 17 22 24 27 28 07 16 27 36 36 16 31 17 27 17 13 03 28 10 14 33 29 31 33 09 15 30 30 08 06 32 22 29 23 25 04 01 05 1919 20 18 18 28 29 17 36 24 20 05 07 30 07 05 10 35 23 23 22 17 19 06 15 04 09 26 27 04 13 23 03 10 18 11 25 12 20 26 03 08 14 10 27 03 26 30 29 14 34 22 28 21 15 17 09 15 09 27 1618 22 1921 15 34 01 03 28 29 28 35 10 36 14 16 15 34 27 22 08 27 05 03 10 15 12 34 03 22 27 30 33 02 01 27 20 03 3433 33 17 28 07 25 04 17 35 22 01 10 29 34 34 18 15 22 09 33 27 27 26 15 35 03 34 10 15 10 34 22 08 27 10 03 15 16 09 22 15 32 27 28 03 22 10 02 25 17 19 ¯ Service Layer Credits: Esri, HERE, Garmin, © OpenStreetMap contributors, and the GIS user community - 1/15/2019 FIGURE 2-1COLLIER COUNTY 10-YEAR WATER SUPPLY FACILITIES WORK PLANWATER SEWER DISTRICT BOUNDARIES OF COLLIER COUNTY 0 1 2 3 4 Miles Legend Ave Maria Big Cypress Everglades City Immokalee WSD City of Marco Island Marco Shores City of Naples Chokoloskee MunicipalService Taxing Unit(Everglades City) Port of the IslandsCommunity ImprovementDistrict Collier CountyWater/Sewer District NOTE: The CCWSD anticipates serving theBig Cypress Stewardship District, pendingnegotiation of an interlocal agreement.

Demand is provided as Annual Average Daily Demand (AADD). AADD is the projected population multiplied by the adopted Level of Service Standard (LOSS) or the Per Capita Use Rate (PCUR) in the absence of an adopted LOSS. 3.1 Collier County Water-Sewer District (CCWSD) Table 3-1 shows population and demand projections for the CCWSD service area. Population projections are taken from the 2018 AUIR and represent the population on October 1 of the given calendar year, which is the beginning of the subsequent fiscal year. Projections include the populations in the former service areas of the Orange Tree Utility Company and the Florida Governmental Utility Authority, which were acquired by the CCWSD in March 2017 and March 2018 respectively. Also, in September 2018, the Board of County Commissioners approved Resolution No. 2018- 152, expanding the CCWSD’s service area to include all unincorporated areas of the county not lying within service areas granted to third parties by the Water and Sewer Regulatory Authority or as otherwise excepted by the special act that created the CCWSD. The jurisdictional boundary of the CCWSD shown in Figure 2-1 encompasses an area of high growth potential within the Rural Lands Stewardship Area known as the Northeast Service Area (NESA). The population projections in Table 3-1 include anticipated growth associated with four large developments planned in the NESA. One of these, River Grass Village, is in the Big Cypress Stewardship District, which has the right to form its own utility, but Collier County has engaged in negotiations with the developer to provide water, wastewater, and irrigation quality water services. Population projections for the village are included in anticipation of a future interlocal agreement. Refer to the 2018 AUIR in Appendix E for further information about the population projections for the CCWSD. Per Policy 1.5 of the Capital Improvement Element of the Collier County Growth Management Plan (as of Ordinance No. 2017-21 adopted June 13, 2017), the adopted Level of Service Standard (LOSS) for the County potable water system is 150 gallons per capita per day (gpcd). All concurrency planning is based on this LOSS despite the PCUR averaging about 140 gpcd over the past 11 years, based on local water data and population estimates (129 gpcd per Table B-2 of the LWCWSP). The PCUR for the CCWSD is notably higher than those for the two other major utilities because the CCWSD service area includes a larger seasonal population, a larger commuting workforce, a higher rate of tourism, more commercial activity, and a higher proportion of customers who irrigate with potable water. The aggregate annual demand includes all these non-residential uses and is divided by the permanent population to obtain the PCUR. Note that the City of Naples has a higher PCUR than the CCWSD (281 per Table B-2 of the LWCWSP) for the same reasons. 17.A.d Packet Pg. 1862 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 3 · Population and Demand Projections 3-2 PW/6295/231366/03/01 As explained in the 2018 AUIR (Appendix E), the CCWSD evaluates required treatment capacity based upon the maximum three-day average daily demand, which is calculated using a peaking factor of 1.3, as established by the Board approved 2014 Water, Wastewater, Irrigation Quality Water and Bulk Potable Water Master Plan/CIP Plan.

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. 17.A.d Packet Pg. 1865 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - GOLDEN GATE BLVD I M M O K A L E E R D COLLIER BLVDLOGAN BLVD")864 ")846 ")951 PINE RIDGE RD ")862 NORTH HAWTHORNRO WELLFIELD GOLDEN GATETAMIAMI WELLFIELD SOUTH HAWTHORNRO WELLFIELD ")858 §¨¦75 UV84 UV93 OTWTP SCRWTP NCRWTP Service Layer Credits: Esri, HERE, Garmin, © OpenStreetMap contributors, and the GIS user community - 9/26/2018 ¯0 1 2 3 4 Miles FIGURE 4-1COLLIER COUNTY 10-YEAR WATER SUPPLY FACILITIES WORK PLANEXISTING CCWSD WELLFIELD S AN D RAW WATER TRANSMISSION M AINS Legend !(Supply Well 3Q Water Treatm ent Plant Raw Water M ain 17.A.d Packet Pg. 1866 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - 3Q 3Q 3Q ")951 I M M O K A L E E R D TAMIAMI TRAIL ")858 GOODLETTE FRANK RD§¨¦75 §¨¦75 £¤41 UV45 ")92 £¤41 £¤41 ")846 UV84 ")951 UV93 OTWTP SCRWTP NCRWTP Service Layer Credits: Esri, HERE, Garmin, © OpenStreetMap contributors, and the GIS user community - 9/26/2018 ¯0 1 2 3 4 Miles FIGURE 4-2COLLIER COUNTY 10-YEAR WATER SUPPLY FACILITIES WORK PLANEXISTING CCWSD POTABLE WATER TREATM EN T FACILITIES Legend 3Q Water Treatm ent Plant 17.A.d Packet Pg. 1867 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 4 · Existing Water Supply Facilities 4-5 PW/6295/231366/03/01 Table 4-2.

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. Table 4-7.

Currently, the system includes 1,604 service connections with a maximum day demand of 23 MGD. The majority of the existing customer base is golf courses, residential communities, environmental mitigation areas, county parks, and roadway medians. The demand for IQ water is seasonal, as is the available supply. Late April through early June is the critical supply/demand period. Combined wastewater flow during this period to both WRFs can be as low as 15 MGD, and can be supplemented with up to 6 MGD of groundwater, providing a total of approximately 21 MGD, leaving a shortfall of approximately 2 MGD of IQ water. There is an additional 28.5 MGD of potential demand in the service area from entities that have installed dual distribution piping. 4.1.3.1 Water Reclamation Facilities CCWSD currently operates two water reclamation facilities (WRFs). The North County Water Reclamation Facility (NCWRF) and the South County Water Reclamation Facility (SCWRF), which are shown in Figure 4-5.

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 Irrigation Quality (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) for 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 as needed to meet peak demands. With both wells operational, they are expected to provide between 1 and 2 MGD of storage and recovery capacity. 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 30.47 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 17.A.d Packet Pg. 1886 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - 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 Surficial Aquifer System (SAS) and Intermediate Aquifer System (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 17.A.d Packet Pg. 1887 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 5 · Planned Water Supply Facilities 5-3 PW/6295/231366/03/01 credits in accordance with new Florida Department of Environmental Protection and SFWMD 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. 17.A.d Packet Pg. 1894 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - ")951 BONITA BEACH R D I M M O K A L E E R D GOODLETTE FRANK RDTAMIAMI TRAIL ")858 §¨¦75 §¨¦75 £¤41 UV45 ")92 £¤41 £¤41 ")846 UV84 ")951 UV93 36''20''3 6 '' 12'' 16'' 30''48''1 8 '' 42'' 1 4 '' 24''12''12''24 ''12''12'' 12''12''12''24''36''16''12'' 36''12''12'' 16'' 12'' 1 2''12''16''12''12''12''24''20''12''16''16''12''30''12''16''20'' 24''16''12''30''12''12''12'' 16'' 16''16''16' '12''12''16''24''12''16''1 2'' 1 2 ''12''12''12''12' ' 16''12'' 20'' 12''16''12''Service Layer Credits: Esri, HERE, Garmin, © OpenStreetMap contributors, and the GIS user community - 9/27/2018 ¯0 1 2 3 4 Miles FIGURE 5-4COLLIER COUNTY 10-YEAR WATER SUPPLY FACILITIES WORK PLANEXISTING AND PLANNED CCW SD POTABL E WAT ER TRAN SM ISSION MAINS Legend Transmission Main Potable Water Main (>= 12") 17.A.d Packet Pg. 1895 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 5 · Planned Water Supply Facilities 5-11 PW/6295/231366/03/01 5.1.2 Reclaimed Water Facilities CCWSD currently operates one of the largest reclaimed water systems in South Florida, which serves customers with contractual commitments of 23.0 MGD. 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.

AMUC believes it will be able to utilize 100 percent of the reclaim water generated. 17.A.d Packet Pg. 1903 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - 6-1 PW/6295/231366/03/01 Section 6 Facilities Capacity Analysis Sections 3, 4, and 5 of this plan presented the population and associated water demand of the areas served and to be served by each utility, the existing water supply facilities in place to meet current demands, and the facilities planned to meet future water supply needs, respectively. The purpose of this section of the plan is to present a comparison of the population, water demand, facilities capacity, and permit limitations that identifies surpluses and deficits in facility and permit capacities. 6.1 Collier County Water-Sewer District (CCWSD) As described in Section 5.1, CCWSD plans to bring online a new potable water treatment facility and associated wellfield during the 10-year planning period ending in 2028. Table 6-1 illustrates how these additions to the existing system will allow CCWSD to stay ahead of the demand curve during the 10-year planning period. Table 6-1.

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.

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: In an effort to conserve water resources, the Collier County Board of Commissioners enacted the first water irrigation ordinance on September 26, 2000 with the adoption of Ordinance No. 2000- 61. Ordinance No. 2002-17, adopted on April 9, 2002, supplemented Ordinance No. 2000-61 with more restrictive irrigation hours and operational requirements. Ordinance No. 2015-27, adopted on April 28, 2015 and titled “Water Conservation Ordinance for Landscape Irrigation,” repealed and replaced the first two ordinances and provided for local implementation of the SFWMD’s mandatory year-round landscape irrigation conservation measures pursuant to Chapter 40E-24, F.A.C. The provisions of the County’s ordinance mirror the rules of the SFWMD but apply to all water resources, including IQ (reclaimed) water, which is exempt from the restricted hours of irrigation under the SFWMD’s rules. Collier County seeks to conserve their valuable IQ water supply as they do with their potable water supply. As such, the Board initiated an ASR program to allow for the storage of excess IQ water that can later be withdrawn to offset peak usage. Other water conservation measures implemented by Collier County include: Enforcing the use of low-flow plumbing fixtures pursuant to section 604.4 of the Florida Building Code, Plumbing, 6th Edition (2017); Landscaping standards in the County’s Land Development Code (LDC 4.06.00) that encourage the use of native and drought-tolerant vegetation and properly zoned irrigation systems through xeriscape; 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 water, to reduce irrigation withdrawals; Filter backwashing at the SCRWTP to eliminate water lost in cleaning filters; 17.A.d Packet Pg. 1908 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 7 · Conservation Regulations and Practices 7-2 PW/6295/231366/03/01 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 only high-use consumers. Requiring subdivisions to have separate potable and reuse water lines and prohibiting the use of County potable water for irrigation where other sources of supplemental water are permitted and available (LDC 4.03.08 C). 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. 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. 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. CCWSD has made significant strides towards improving and enhancing the efficiency of its 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 had been maintained below five percent for eight years starting with 2008, markedly lower than preceding years, but peaked again in 2017 for reasons outlined below. Four noteworthy events during the 2017 fiscal year significantly impacted the amount of unaccounted-for water loss in the CCWSD’s water distribution system. The cumulative effect of the following four events was an anomalous loss of water compared with the previous nine years: · Catastrophic impact of Hurricane Irma, which caused more than 100 water main breaks, over 400 water service breaks, and damage to numerous fire hydrants, resulting in a total loss of system pressure and nearly a complete dewatering of the distribution network, · Repeated flushing of an inactive 6-mile long 36” water transmission main, constructed in 2005, to bring it into service, · An unusually active wildfire season that required water for combatting blazes that threatened homes in the Rural Estates and along Collier Boulevard · Two large-diameter water transmission main breaks near the intersection of I-75 and Collier Boulevard 17.A.d Packet Pg. 1909 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 7 · Conservation and Practices 7-3 PW/6295/231366/03/01 Figure 7-1 CCWSD Unaccounted-for Water Loss from FY2004 to FY20181 1 The CCWSD Unaccounted-for Water Loss from FY2004 to FY2013 was taken from the 2013 Plan Update. Specific projects the CCWSD has completed 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 an additional 20 valves per year to facilitate positive and timely isolation and reduce water loss in the event of a water main break . Mapping new areas incorporated into the district, including Golden Gate City, and North East Service Area (i.e. Orange Tree Utility) to locate and record valves (and other appurtenances) in the GIS database so that water loss can be reduced by timely isolation in the event of a water main break. 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 to ensure the accurate measurement of authorized water usage accounting and billing. 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 in FY 2019. Continue utilizing a GIS-centric enterprise asset management system (Cityworks) to record the frequency of water main breaks by location and identify areas where water mains need to be programmatically replaced, reducing the potential for water loss. 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% 6.6% 0.0% 2.5% 5.0% 7.5% 10.0% 12.5% 15.0%200420052006200720082009201020112012201320142015201620172018Percentage of Unaccounted-for Water LossFiscal Year 17.A.d Packet Pg. 1910 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 7 · Conservation Regulations and Practices 7-4 PW/6295/231366/03/01 Changes made to the Utility Standards Manual require developers to provide automatic flushing devices (AFD) at dead ends and mid-points of certain looped water mains to maintain disinfectant residuals. AFDs discharge less water over time in comparison to manual flushing through fire hydrants. Collier County is actively completing water main looping projects and requires all new potable water distribution systems to be looped. Looping conserves water by eliminating dead ends which must be flushed to maintain minimum disinfectant residuals. · Collier County’s water main looping projects that have been completed over the past five years are: o Wilshire Lakes, o Tree Farm 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. Utilizing leak detection contractual services to identify leaks in older areas of the water distribution system and programmatically making repairs to reduce water loss. 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 17.A.d Packet Pg. 1911 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 7 · Conservation and Practices 7-5 PW/6295/231366/03/01 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. 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. 17.A.d Packet Pg. 1912 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 7 · Conservation Regulations and Practices 7-6 PW/6295/231366/03/01 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. 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 17.A.d Packet Pg. 1913 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 7 · Conservation and Practices 7-7 PW/6295/231366/03/01 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. 17.A.d Packet Pg. 1914 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - Section 7 · Conservation Regulations and Practices 7-8 PW/6295/231366/03/01 This page intentionally left blank. 17.A.d Packet Pg. 1915 Attachment: BCC Version_10-Yr Water Supply Facilities Work Plan-CleanVersion-February 2019 (8397 : Ten Year Water Facilities Supply Plan - 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 CCWSD’s water supply development projects identified in the Work Plan are per the update done for the 2018 AUIR. 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).

B. C. D. E. Recommendation The Public Utilities Department’s staff recommends that the Collier County Board of County Commissioners approve the 2018 CCWSD Potable Water System Treatment Facilities AUIR. Collier County Government The 2018 Potable Water System AUIR is presented as a snapshot of concurrency conditions. The CCWSD is in compliance with concurrency requirements for FY 2019 and FY 2020, as required by FS Section 163, the Collier County Comprehensive Plan, and the Land Development Code. POTABLE WATER SYSTEM - TREATMENT FACILITIES 2018 ANNUAL UPDATE AND INVENTORY REPORT (AUIR) Public Utilities Department The Public Utilities Department’s proposed 2018 Potable Water System Treatment Facilities AUIR is based on permanent population estimates and projections for the potable water service area prepared by the Collier County Comprehensive Planning Section on June 15, 2018. Populations are based on using the Bureau of Economic and Business Research (BEBR) Medium Range growth rate through 2028. Concurrency is shown for 10 years for the current service area. This conforms with the State mandated CIE, concurrency regulations, and other Collier County Departments' AUIR submittals. The Collier County Water-Sewer District (CCWSD) acquired the Golden Gate City potable water and wastewater utility systems from the Florida Governmental Utility Authority on March 1, 2018. The Public Utilities Department has solicited new master plans for water, wastewater, and irrigation quality water under RPS 18-7370, with an anticipated completion in FY 2020. To serve the current potable water service area, shown in blue in the "Current and Future Water Service Areas" map, and to support forecasted growth in the northeast region of the county, 5 MGD of new treatment capacity will be needed by FY 2028. This will be achieved through phased construction of a new regional water treatment plant at the Northeast Utility Facilities (NEUF) site. The NEUF are sited on 147 acres of County owned land at the east end of 39th Ave NE. 100% design documents were completed in 2010. The NEUF program has been reactivated, starting with updating the design criteria (FY 2018) and modifying the design plans to conform with current technologies (FY 2018-2019). To facilitate reactivation, site work is planned to begin in FY 2019. Project reactivation is in anticipation of the quantity of large developments going through different stages of the Growth Management Department review process. The need for readiness is also supported by the “Collier County Water- Sewer District System Utilization and Diminishing Capacity Report” (the “Checkbook”) which compares available treatment capacity to the quantity of Board-approved planned unit developments (PUDs). Currently, the Checkbook reports that if all active Board-approved PUDs within the current service area were to be constructed, there would be a 1% surplus in potable water treatment capacity in the regional system. INTRODUCTION On September 11, 2018, as Agenda Item 17.F, the Board adopted a resolution expanding the CCWSD's service area to coincide with the unincorporated area permitted by Chapter 2003-353, Laws of Florida. This "jurisdictional boundary"is depicted on the subsequent map entitled, "Collier County Water-Sewer District Water Service Jurisdiction," and encompasses the planned developments known as "Rural Lands West," "Winchester Lakes," and "Hogan Island Village," as depicted on the subsequent map entitled, "Future Development in Northeast Collier County." Notes The BEBR population numbers are supplemented by estimates per the implementation plan for the Golden Gate City service area, as reported in the "Technical Feasibility Study for Acquisition of FGUA Water and Wastewater Assets in Golden Gate" prepared by Stantec Consulting Services Inc., and by preliminary model results provided by Metro Forecasting Models, LLC from the Collier Interactive Growth Model for the planned developments in the expanded Northeast Service Area (i.e. Rural Lands West, Winchester Lakes, and Hogan Island Village).

New Treatment Capacity Permanent Population Served on Oct. 1. Estimates and projections for the served area were prepared by the Collier County Comprehensive Planning Section on June 15, 2018. Populations are based on the Bureau of Economic and Business Research (BEBR) Medium Range growth rate applied through 2028. Permanent population is used in accordance with the Board adopted 2014 Water, Wastewater, Irrigation Quality Water and Bulk Potable Water Master/CIP Plan. The population projections include the NE Utility WTP (formerly Orange Tree Utilities - OTU) service area beginning in FY 2018 and the Golden Gate City service area (approximately 4 square miles) beginning in FY 2019 based on acquisition dates during FY 2017 and FY 2018 respectively. The CCWSD presently supplies potable water to a population of approximately 12,404 in Golden Gate City. Based on the implementation plan outlined in the Board adopted "Technical Feasibility Study for Acquisition of FGUA Water and Wastewater Assets in Golden Gate," Phase 2 will increase the population served to 21,285 within 10 years. Required Treatment Capacity at Max. TDADD is obtained by multiplying the Permanent Population Served on Oct. 1 by 150 gallons per capita per day (gpcd) and by a maximum 3-day average daily demand (TDADD) peaking factor of 1.3 and is expressed in million gallons per day (MGD). 150 gpcd is the established Level of Service (LOS) Standard for the Potable Fiscal Year Comments and Cost Estimates Design and permitting updates for additional potable water treatment capacity at the NEUF started in FY 2018 and will be online in FY 2028, as follows: a.

Capacity in FY 2018 increased by 0.75 MGD (as currently sited) because Orange Tree Utilities (OTU) was integrated into the CCWSD on March 1, 2017, during FY 2017. Acquisition of the Golden Gate City Utility from the Florida Governmental Utility Authority occurred on March 1, 2018. Existing Golden Gate City Utility potable water facilities include a 2.1 MGD water treatment plant; however, no additional capacity is stated because this area is now served by the nearby CCWSD regional potable water system. Unused Golden Gate City Utility assets are being repurposed and/or decommissioned, depending on condition. Twin Eagles potable water services transitioned from the NE Utility WTP (former OTU) to the CCWSD Regional potable water system on December 18, 2017. All customers within the Orange Tree PUD and the Orange Blossom Ranch PUD as well as the Corkscrew Elementary/Middle and the Palmetto Ridge High public school campuses were diverted through reliability interconnects over the course of FY 2018. Percent of Total Permitted Capacity (Max. Day) is the total maximum-day quantity of finished water produced by all treatment plants connected to the water system as a percentage of Total Permitted Treatment Capacity. Per FAC 62-555.348, source/treatment/storage capacity analysis reporting to the Department of Environmental Protection (DEP) is triggered once maximum-day demand exceeds 75% of Total Permitted Treatment Capacity, as plotted in the chart on the next page. In accordance with the Board adopted 2014 Water, Wastewater, Irrigation Quality Water and Bulk Potable Water Master/CIP Plan, Total Operational Treatment Capacity must be sufficient for the max. TDADD. Retained Operational Treatment Capacity is the Total Operational Treatment Capacity minus the Required Treatment Capacity at Max. TDADD. Total Permitted Treatment Capacity is the total permitted finished water treatment capacity at the beginning of the fiscal year in million gallons per day (MGD), including New Treatment Capacity. Total Operational Treatment Capacity is the Total Permitted Treatment Capacity less 4 MGD, the treatment capacity of a lime softening reactor/clarifier, which could be out of service during a period of peak demand, as plotted in the chart on the next page.

Summary (8397 : Ten Year Water Facilities Supply Plan - February 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 Section 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 in December 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 May 15, 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 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. 17.A.h Packet Pg. 1986 Attachment: Transmittal Ex. Summary_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) • 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 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). 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. The Board should consider the following criteria in making its decision: “plan amendments shall be based on relevant and appropriate data and an analysis by the local government that may include but not be limited to, surveys, studies, community goals and vision, and other data available at the time of adoption of the plan amendment. To be based on data means to react to it in an appropriate way and to the extent necessary indicated by the data available on that particular subject at the time of adoption of the plan or plan amend ment at issue.” 163.3177(1)(f), F.S. This item is approved as to form and legality. It requires a majority vote because this is a transmittal hearing of the GMP amendment. [SAS] GROWTH MANAGEMENT IMPACT: Adoption of the ten-year water supply plan update and subsequent amendment to the Potable Water Sub element of the Growth Management Plan will satisfy the requirements of 163.3177(6)(c), F.S.

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.i Packet Pg. 1989 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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 “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.i Packet Pg. 1991 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.i Packet Pg. 1992 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.i Packet Pg. 1993 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.i Packet Pg. 1994 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.i Packet Pg. 1995 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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. LEGAL CONSIDERATIONS: This staff report has been reviewed and approved by the Office of the County Attorney. STAFF RECOMMENDATION: That the Collier County Planning Commission, sitting as the Environmental Advisory Council under Ordinances 2013-50 and 2013-51, and in its capacity as the local planning agency under Ch. 163.3174, F.S., forward Petition PL20180002552/CPSP-2018-6 to the Board of County Commissioners with a recommendation to approve for Transmittal to the Florida Department of Economic Opportunity. 17.A.i Packet Pg. 1996 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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 10 17.A.i Packet Pg. 1997 Attachment: Transmittal Staff Report_2_FNL (8397 : Ten Year Water Facilities Supply Plan - February 2019) Attachment A Collier County Planning Commission – December 6, 2018 Item 9.A.4 – Discussion of the 10-Year Water Supply Facilities Work Plan Update Time Speaker Comments/Questions 22:00 Fryer Signature block of Resolution has Dwight Brock’s name. 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.j Packet Pg. 1998 Attachment: Transmittal Attachment A (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.j Packet Pg. 1999 Attachment: Transmittal Attachment A (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.j Packet Pg. 2000 Attachment: Transmittal Attachment A (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.j Packet Pg. 2001 Attachment: Transmittal Attachment A (8397 : Ten Year Water Facilities Supply Plan - February 2019) 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.

We have completed an informal review of the Work Plan and offer the following comments (note: the comments are in no particular order): · Update Table ES-3 Summary of Existing and Planned IWSD Water Treatment Facilities (page ES-4) to reflect current information provided to the District on December 7, 2018. The Carson Road WTP capacity is listed as 2.58 MGD and the RO WTP expected to be online in 2020. According an email from Eva Deyo, Utility Director, the Carson WTP capacity is 2.0 MGD and the RO plant is expected to be online in 2026. We will revise Table ES-3 to reflect the RO WTP coming online in 2026 with a design treatment capacity of 2.0 MGD. · Revise Table 4.4 Existing South Hawthorn RO Wellfield Summary (pages 4-7 – 4-8) as follows: o Update the pump capacity for wells from 1S to 25S and 13s to 15s to be consistent with Table A in Application 180309-16. Table 4-4 will be revised to be consistent with Table A in Application 180309-16. o Wells 39S to 42S are duplicated on Table 4-4. The wells appear on page 4-7 (rows 16 and 19) and then again on page 4-8 (rows 5 and 8). Please revise Table 4-4 accordingly. The duplicate information in rows 16 – 19 on page 4-7 will be deleted. · Update Well D on Table 4-5 Existing Orange Tree Wellfield Summary (page 4-8) to be consistent with application 180111-21. The total depth for Well D on Table 4-5 is 172 ft. The total depth of Well D in Table A of Application 180111-21 is 180 ft. Table 4-5 will be revised to indicate a total well depth of 180 feet for Well D. · Update Table 4-11 Summary of Existing IWSD Potable Water Wells (page 4-18), to be consistent with the details for Wells 7 to 13, 101 to 106, and 204 in Application 120808-32 Table A. Table 4-11 will be revised to be consistent with Table A in Application 120808-32. · Include the Relevant Regional Issues from the Lower West Coast Water Supply Plan. This section is intended to briefly address overarching regional issues impacting water supply planning at the local level, such as the adoption of rules affecting availability of water, a Sector Plan, or other large-scale Attachment B 17.A.k Packet Pg. 2003 Attachment: Transmittal Attachment B (8397 : Ten Year Water Facilities Supply Plan - February 2019) 3 development. Include a narrative of the effects of identified regional issues on the County. Also describe the County’s policies addressing regional concerns. Detailed information on the regional issues can be found in Chapter 6, Water Resource Issues and Analyses, in the Lower West Coast Water Supply Plan. The information can be accessed at: https://www.sfwmd.gov/our-work/water-supply/lower-west-coast The regional issues for the Lower West Coast Water Supply Plan are: Increased withdrawals from the Surficial Aquifer and Intermediate Aquifer Systems are limited This is already addressed in Section 5.1 of the County’s plan. Lake Okeechobee Service Area Restricted Allocation Area criteria This applies to surface water allocations from Lake Okeechobee and hydraulically connected surface water, which the County does not use as source. Freshwater discharges to the Caloosahatchee Estuary Collier County is effectively not in the Caloosahatchee Watershed (see below map). · Include the proposed revisions to the Comprehensive Plan’s Goals, Objectives, and Policies for consistency with the proposed Work Plan update. Updates should include, but not be limited to, Attachment B 17.A.k Packet Pg. 2004 Attachment: Transmittal Attachment B (8397 : Ten Year Water Facilities Supply Plan - February 2019) 4 changes to conservation programs, level of service standards, capital improvements, population projections, and other details updated by the Work Plan.

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 a 10-Year Water Supply Facilities Work Plan Update and amendments to the Growth Management Plan (GMP). Under the requirement of the Florida Statutes, the 10-Year Water Supply Facilities Work Plan Update (Plan Update) 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 Update to be included in its city’s comprehensive plan. This 10-Year Water Supply Facilities WorkThis 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 Update. Where information gaps existed, information on the existing and planned facilities was gathered from various sources including the SFWMD LWCWSP updateUpdate, 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 Update, 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.

In addition to the construction of the planned facilities indicated above, CCWSD intends to construct new wellfields, finished water storage, and distribution lines, which are presented in detail in the Plan Update. The information on CCWSD is reflective of the 2014 Water and Wastewater Master Plan Updates, the Collier County 2018 Draft Annual Update and Inventory Report (AUIR) on public utilitiesfor Public Utilities, and the Collier County Water-Sewer District Fiscal Year 2017-2027 Capital Improvement Plan. The 2018 AUIR and the Fiscal Year 2017-2027 Capital Improvement Plan were approved by the Collier County Board of County Commissioners on November 13, 2018. Based on population projections available for the CCWSD service area, a capacity analysis was performed looking at projected demand versus plant capacity and permitted allocation. The results of the capacity analysis are summarized below in Table ES-2. A discussion of the capacity analysis can be found in Section 6.1. As the capacity analysis illustrates, CCWSD has sufficient plant capacity existing or planned plant capacity throughout the 2028 planning horizon. Table ES-2.

It is calculated by multiplying the Required Treatment Capacity by the Raw to Finished Water Adjustment. 4 CUP (11-02298-W) allocation is 1.16 MGD annual average and expires on October 19, 2020. 5 Calculated by subtracting the Raw Water Requirement from the Permitted Amount. 6 Population estimates/projections provided by AMUC; 2013 population is an interpolated value Executive Summary · ES-6 PW/6295/231366/03/01 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 CUP allocation (11-02298-W) only covers the withdrawals required to makemeet 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. 1-1 PW/6295/231366/03/01 Section 1 Introduction 1.1 Plan Background In December 2017, the Governing Board of the South Florida Water Management District (SFWMD) approved the 2017 Lower West Coast Water Supply Plan Update (LWCWSP). 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 Update and amendments to the Growth Management Plan (GMP). Under the requirement of the Florida Statutes, the 10-Year Water Supply Facilities Work Plan Update (Plan Update) 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. 1.2 Plan Objectives This 10-Year Water Supply Facilities Work Plan Update (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 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.

Section 1 · Introduction 1-4 PW/6295/231366/03/01 This page intentionally left blank. 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 Orange Tree Utility Company (OTUC) was taken over by the CCWSD on March 1, 2017. 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 Section 2 · Water Service Areas 2-2 PW/6295/231366/03/01 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. 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 interconnectionsThe CCWSD maintains an interconnection with Marco Shores by which CCWSD supplies potable water on a bulk basis, CCWSD also. The City of Marco Island has provided written notification to CCWSD that the Potable Water Bulk Services Water Agreement will be terminated on or around September 26, 2019. [Letter from City of Marco Island to the County attached as Appendix D] The CCWSD 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. Section 2 · Water Service Areas 2-3 PW/6295/231366/03/01 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. The outlying unincorporated communities served by the City include Plantation Island and Seaboard Village in Copeland. 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. Section 2 · Water Service Areas 2-4 PW/6295/231366/03/01 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. 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. §¨¦75 UV93 ")858 UV82 UV951 ")92 ")865 ")850 UV876 UV84 UV29 UV90 UV864 §¨¦75 £¤41 ")846 UV45 £¤41 ")951 UV45 ")846 UV29 UV93 £¤41 05 040106020304050601030205 11 06 01 04 11 08 02 07 02 12 0601 36 03 13 06 09 35 03 07 11 04 11 01 07 32 10 31 05 01 34 08 12 03 05 14 06 10 36 06 02 11 08 1517 10 21 09 12 33 31 11 24 19 11 33 18 11 05 31 36 05 08 04 3432 25 11 11 06 11 11 04 25 11 10 07 30 01 11 14 19 11 11 10 31 18 35 30 13 08 32 33 22 15 09 11 23 22 03 11 36 05 07 11 14 09 15 12 13 27 34 27 34 04 09 34 36 08 11 08 13 11 04 11 04 04 16 03 20 26 11 25 33 05 30 26 12 32 31 16 30 22 11 04 04 33 24 09 17 31 33 19 0103 31 08 15 35 07 05 35 36 09 16 04 19 27 34 28 20 25 06 10 01 30 26 31 32 27 24 34 10 18 36 09 20 21 19 30 08 16 28 06 36 04 13 05 16 11 14 10 23 28 24 33 33 06 35 09 02 31 20 29 12 18 32 28 26 08 18 03 18 03 06 16 28 34 19 17 29 10 02 29 15 2528 06 17 12 11 09 03 35 02 26 19 32 32 14 13 21 0907 07 33 36 07 26 13 17 34 05 22 17 12 33 08 12 28 36 30 32 13 20 1614 21 33 12 13 09 14 25 21 18 06 25 07 33 34 18 15 04 31 36 01 25 09 30 20 21 31 17 07 35 25 21 18 31 31 14 09 19 33 29 32 23 09 23 17 27 15 30 36 05 04 33 32 23 25 26 24 02 18 02 16 02 35 25 18 35 1514 33 22 08 01 13 20 03 14 10 06 29 07 20 25 06 18 32 25 25 02 08 12 24 19 34 32 33 26 31 34 29 01 20 31 27 17 14 16 1416 08 35 08 13 27 15 26 33 35 05 15 19 02 18 28 23 26 13 14 14 23 12 07 02 33 25 15 30 27 06 36 02 07 18 02 17 29 05 01 22 08 29 20 09 30 08 21 22 28 29 27 04 17 21 01 03 07 35 19 08 33 23 16 24 05 10 29 28 35 10 07 25 13 30 35 08 10 12 02 20 13 18 12 04 29 12 13 13 07 16 10 14 28 20 30 16 12 15 24 30 16 01 24 16 21 07 34 32 08 34 12 13 30 20 27 34 26 17 28 13 17 19 04 36 20 14 24 32 08 01 07 36 05 17 08 21 02 14 30 28 24 16 27 23 32 19 34 05 19 16 14 32 30 07 29 14 10 14 05 32 21 12 23 15 12 24 16 21 15 06 25 24 16 22 01 24 26 10 03 01 02 19 12 23 06 26 24 33 25 13 25 12 09 04 01 31 31 02 27 17 29 10 15 29 34 21 26 26 22 32 20 29 1516 29 15 13 24 21 17 06 19 0402 11 18 18 33 09 15 07 29 27 33 30 27 34 23 32 26 13 03 25 22 20 17 29 05 08 23 09 14 20 31 15 27 25 20 20 19 25 12 13 05 32 10 13 30 19 20 01 05 19 23 17 10 01 32 18 09 19 24 23 27 06 22 28 28 19 20 21 16 36 18 03 10 08 29 17 33 19 17 26 23 05 15 12 35 05 14 33 20 18 24 24 17 32 26 21 32 29 22 07 13 28 36 2423 04 04 21 26 16 21 10 04 21 16 34 35 23 08 09 05 26 13 08 28 21 24 22 33 08 32 19 03 35 31 17 28 05 2321 18 06 01 36 24 32 18 28 21 01 25 22 19 22 33 30 04 16 32 20 26 14 35 29 35 14 16 07 12 06 2024 13 22 28 30 09 06 31 28 23 21 05 26 07 23 27 05 31 20 28 34 02 23 22 21 29 24 19 09 06 18 16 04 21 22 07 12 36 10 17 21 09 29 03 12 35 22 20 28 08 10 04 09 35 04 16 21 03 16 06 35 06 03 02 31 19 27 20 36 01 30 36 18 20 28 21 27 06 08 30 21 16 05 22 24 31 28 06 04 18 29 31 10 36 29 17 01 30 08 12 06 34 31 07 07 31 16 07 23 15 02 21 02 28 09 28 09 34 07 26 32 09 15 22 18 04 03 25 08 24 09 09 09 03 17 22 24 27 28 07 16 27 36 36 16 31 17 27 17 13 03 28 10 14 33 29 31 33 09 15 30 30 08 06 32 22 29 23 25 04 01 05 1919 20 18 18 28 29 17 36 24 20 05 07 30 07 05 10 35 23 23 22 17 19 06 15 04 09 26 27 04 13 23 03 10 18 11 25 12 20 26 03 08 14 10 27 03 26 30 29 14 34 22 28 21 15 17 09 15 09 27 1618 22 1921 15 34 01 03 28 29 28 35 10 36 14 16 15 34 27 22 08 27 05 03 10 15 12 34 03 22 27 30 33 02 01 27 20 03 3433 33 17 28 07 25 04 17 35 22 01 10 29 34 34 18 15 22 09 33 27 27 26 15 35 03 34 10 15 10 34 22 08 27 10 03 15 16 09 22 15 32 27 28 03 22 10 02 25 17 19 ¯ Service Layer Credits: Esri, HERE, Garmin, © OpenStreetMap contributors, and the GIS user community - 1/15/2019 FIGURE 2-1COLLIER COUNTY 10-YEAR WATER SUPPLY FACILITIES WORK PLANWATER SEWER DISTRICT BOUNDARIES OF COLLIER COUNTY 0 1 2 3 4 Miles Legend Ave Maria Big Cypress Everglades City Immokalee WSD City of Marco Island Marco Shores City of Naples Chokoloskee MunicipalService Taxing Unit(Everglades City) Port of the IslandsCommunity ImprovementDistrict Collier CountyWater/Sewer District NOTE: The CCWSD anticipates serving theBig Cypress Stewardship District, pendingnegotiation of an interlocal agreement.

Demand is provided as Annual Average Daily Demand (AADD). AADD is the projected population multiplied by the individual water supply utilities, such as Master Plans.adopted Level of Service Standard (LOSS) or the Per Capita Use Rate (PCUR) in the absence of an adopted LOSS. 3.1 Collier County Water-Sewer District (CCWSD) Table 3-1 shows population and demand projections for the CCWSD service area. Population projections through 2028 are included in the following sub-sectionsare taken from the 2018 AUIR and represent the population on October 1 of the given calendar year, which is the beginning of the subsequent fiscal year. Projections include the populations in the former service areas of the Orange Tree Utility Company and the Florida Governmental Utility Authority, which were acquired by the CCWSD in March 2017 and March 2018 respectively. 3.1 Countywide Projections Table 3-1 shows the projected population for Collier County for the 10-year planning period of this plan. The population projections are for peak season, which is one key basis for planning and sizing of facilities. Also, in September 2018, the Board of County Commissioners approved Resolution No. 2018- 152, expanding the CCWSD’s service area to include all unincorporated areas of the county not lying within service areas granted to third parties by the Water and Sewer Regulatory Authority or as otherwise excepted by the special act that created the CCWSD. The jurisdictional boundary of the CCWSD shown in Figure 2-1 encompasses an area of high growth potential within the Rural Lands Stewardship Area known as the Northeast Service Area (NESA). The population projections in Table 3-1 include anticipated growth associated with four large developments planned in the NESA. One of these, the Town of Rural Lands West, is in the Big Cypress Stewardship District, which has the right to form its own utility, but Collier County has engaged in negotiations with the developer to provide water, wastewater, and irrigation quality water services. Population projections for the town are included in anticipation of a future interlocal agreement. Refer to the 2018 AUIR in Appendix E for further information about the population projections for the CCWSD. Per Policy 1.5 of the Capital Improvement Element of the Collier County Growth Management Plan (as of Ordinance No. 2017-21 adopted June 13, 2017), the adopted Level of Service Standard (LOSS) for the County potable water system is 150 gallons per capita per day (gpcd). All concurrency planning is based on this LOSS despite the PCUR averaging about 140 gpcd Section 3 · Population and Demand Projections 3-2 PW/6295/231366/03/01 over the past 11 years, based on local water data and population estimates (129 gpcd per Table B-2 of the LWCWSP). The PCUR for the CCWSD is notably higher than those for the two other major utilities because the CCWSD service area includes a larger seasonal population, a larger commuting workforce, a higher rate of tourism, more commercial activity, and a higher proportion of customers who irrigate with potable water. The aggregate annual demand includes all these non-residential uses and is divided by the permanent population to obtain the PCUR. Note that the City of Naples has a higher PCUR than the CCWSD (281 per Table B-2 of the LWCWSP) for the same reasons. As explained in the 2018 AUIR (Appendix E), the CCWSD evaluates required treatment capacity based upon the maximum three-day average daily demand, which is calculated using a peaking factor of 1.3, as established by the Board approved 2014 Water, Wastewater, Irrigation Quality Water and Bulk Potable Water Master Plan/CIP Plan. The max. TDADD is presented in Table 3-1 along with the AADD. Table 3-1.

The populations are shown in 5-year increments, through 2028. The total population projections include the populations in the Rural Fringe areas, which were incorporated into the CCWSD in 2003 as described in Section 2.2.1.1, and the Orange Tree area which was taken over by CCWSD in 2014.

Section 3 · Population and Demand Projections 3-3 PW/6295/231366/03/01 The adopted Level of Service Standard (LOSS) for the CCWSD is 150 gallons per capita per day (gpcd). Based on the LOSS of 150 gpcd and the population projections presented in Table 3-2, the demand projections for the CCWSD were developed. Table 3-3 presents the projected population and demand for the area served by CCWSD, in 5-year increments, through 2028. Demand is provided as Required Treatment Capacity at 150 gpcd in MGD. Required Treatment Capacity at 150 gpcd is a metric used by Collier County in its Annual Update and Inventory Reports (AUIR) and is used to evaluate the ability of CCWSD facilities to meet peak season demand. It is calculated as the peak season population multiplied by the LOSS of 150 gpcd. Table 3-3.

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.

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.

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 Irrigation Quality (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) for 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 as needed 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 28.6930.47 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 Surficial Aquifer System (SAS) and Intermediate Aquifer System (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 Section 5 · Planned Water Supply Facilities 5-3 PW/6295/231366/03/01 credits in accordance with new Florida Department of Environmental Protection and SFWMD 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.

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.

Section 6 · Facilities Capacity Analysis 6-4 PW/6295/231366/03/01 This page intentionally left blank. 7‐1  PW/6295/231366/03/01  Section 7  Conservation Regulations and Practices  As the water supply in Florida becomes more taxed over time, the need to more efficiently utilize water resources will increase. 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 In an effort to conserve water resources, the Collier County Board of Commissioners enacted the first water irrigation ordinance on September 26, 2000 with the adoption of Ordinance No. 2000‐61. Ordinance No. 2002‐17, adopted on April 9, 2002, supplemented Ordinance No. 2000‐ 61 with more restrictive irrigation hours and operational requirements. Ordinance No. 2015‐27, adopted on April 28, 2015 and titled “Water Conservation Ordinance for Landscape Irrigation,” repealed and replaced the first two ordinances and provided for local implementation of the SFWMD’s mandatory year‐round landscape irrigation conservation measures pursuant to Chapter 40E‐24, F.A.C. The provisions of the County’s ordinance mirror the rules of the SFWMD but apply to all water resources, including IQ (reclaimed) water, 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. Theis exempt from the restricted hours of irrigation under the SFWMD’s rules. Collier County seeks to conserve their valuable IQ water supply as they do with their potable water supply. As such, the Board initiated an ASR program to allow for the storage of excess IQ water that can later be withdrawn to offset peak usage. Other water conservation measures designatedimplemented by the SFWMD, which Collier County has enacted include:  Requiring Enforcing the use of low‐flow plumbing fixtures as part of the pursuant to section 604.4 of the Florida Building Code, Plumbing, 6th Edition (2017);  Landscaping standards in the County’s Land Development Code (LDC);  Encouraging 4.06.00) that encourage the use of Florida Friendly landscapesnative and other drought‐tolerant vegetation in portions of the LDCand properly zoned irrigation systems through xeriscape;  Implementing water conservation rates that increase per‐thousand‐gallon charges as usage increases;  Section 7   Conservation Regulations and Practices  7‐2      PW/6295/231366/03/01   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 wastewaterwater, 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.  Requiring subdivisions to have separate potable and reuse water lines and prohibiting the use of County potable water for irrigation where other sources of supplemental water are permitted and available (LDC 4.03.08 C). 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 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 stationsStations 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 Systemits 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 10had been maintained below five percent for eight years (period betweenstarting with 2008 to 2017) when compared to its, markedly lower than preceding periodyears, but peaked again in 2017 for reasons outlined below. Four noteworthy events during the 2017 fiscal year significantly impacted the amount of unaccounted‐for water loss in the CCWSD’s water distribution system. The cumulative effect of the following four events was an anomalous loss of water compared with the previous nine years:  Catastrophic impact of Hurricane Irma, which caused more than 100 water main breaks, over 400 water service breaks, and damage to numerous fire hydrants, resulting in a total loss of system pressure and nearly a complete dewatering of the distribution network,  Section 7  Conservation and Practices  7‐3  PW/6295/231366/03/01   Repeated flushing of an inactive 6‐mile long 36” water transmission main, constructed in 2005, to bring it into service,  An unusually active wildfire season that required water for combatting blazes that threatened homes in the Rural Estates and along Collier Boulevard  Two large‐diameter water transmission main breaks near the intersection of I‐75 and Collier Boulevard Figure 7‐1 CCWSD Unaccounted‐for Water Loss from FY2002 to FY20171FY20181  1 The CCWSD Unaccounted‐for Water Loss from FY2002 FY2004 to FY2013 was taken from the previous 2013 10‐Year Water Supply Plan Update. 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 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% 6.6% 0.0% 2.5% 5.0% 7.5% 10.0% 12.5% 15.0%200420052006200720082009201020112012201320142015201620172018Percentage of Unaccounted‐for Water LossFiscal Year  Section 7   Conservation Regulations and Practices  7‐4      PW/6295/231366/03/01  Specific projects the CCWSD has completed 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 andan additional (20) valves per year to assist with increase responsiveness to system eventsfacilitate positive and timely isolation and reduce water loss in the event of a water main break .  Mapping new areas incorporated into the district, including Golden Gate City, and North East Service Area (i.e. Orange Tree Utility).) to locate and record valves (and other appurtenances) in the GIS database so that water loss can be reduced by timely isolation in the event of a water main break.  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. to ensure the accurate measurement of authorized water usage accounting and billing. 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,in FY 2019.  On‐going activityContinue utilizing a GIS‐centric enterprise asset management system (Cityworks) to record the frequency of replacingwater main breaks by location and identify areas where water mains utilizing a “just in time” method methodology of replacement. Mains areneed to be programmatically replaced after several failures versus waiting until they become an operational issue. This improves service reliability and fire protection capacity and reduces, reducing the potential for water loss.  Changes made to the Utility Standards Ordinance nowManual require developers of new areas to provide automatic 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 devices (AFD) at dead ends and mid‐points of certain looped water mains to maintain disinfectant residuals. AFDs discharge less water over time in comparison to manual flushing through fire hydrants.  Collier County is actively completing water main looping projects. Looping is promoted by imposing and tracking PUD commitments and through enforcement of design criteria which requirerequires all new potable water distribution systems to be looped. Looping conserves water by eliminating dead ends, which must be flushed to maintain minimum chloraminedisinfectant residuals.  Collier County’s water main looping projects that have been completed over the past five years are: o Wilshire Lakes,  Section 7  Conservation and Practices  7‐5  PW/6295/231366/03/01  o TreefarmTree Farm 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.  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 performUtilizing leak detection for contractual services to identify leaks in older areas of the Water Districtwater distribution system and programmatically making repairs to reduce water loss. 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.  Section 7   Conservation Regulations and Practices  7‐6      PW/6295/231366/03/01  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. 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.  Section 7  Conservation and Practices  7‐7  PW/6295/231366/03/01  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. 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.

Section 1 · Introduction 1-4 PW/6295/231366/03/01 This page intentionally left blank. 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 Orange Tree Utility Company (OTUC) was taken over by the CCWSD on March 1, 2017. The CCWSD acquired the Golden Gate City potable water and wastewater utility systems from FGUA on March 1, 2018. 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 Section 2 · Water Service Areas 2-2 PW/6295/231366/03/01 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. 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. The CCWSD maintains an interconnection with Marco Shores by which CCWSD supplies potable water on a bulk basis. The City of Marco Island has provided written notification to CCWSD that the Potable Water Bulk Services Water Agreement will be terminated on or around September 26, 2019. [Letter from City of Marco Island to the County attached as Appendix D] The CCWSD 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. Section 2 · Water Service Areas 2-3 PW/6295/231366/03/01 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. The outlying unincorporated communities served by the City include Plantation Island and Seaboard Village in Copeland. 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. Section 2 · Water Service Areas 2-4 PW/6295/231366/03/01 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. 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.

The list was developed from the FDEP drinking water database and is accurate as of April 11, 2018. 3-1 PW/6295/231366/03/01 Section 3 Population and Demand Projections In the following sub-sections, population and demand projections for the 10-year planning period are presented in 5-year increments for each of the three major public water supply utilities serving unincorporated Collier County. Demand is provided as Annual Average Daily Demand (AADD). AADD is the projected population multiplied by the adopted Level of Service Standard (LOSS) or the Per Capita Use Rate (PCUR) in the absence of an adopted LOSS. 3.1 Collier County Water-Sewer District (CCWSD) Table 3-1 shows population and demand projections for the CCWSD service area. Population projections are taken from the 2018 AUIR and represent the population on October 1 of the given calendar year, which is the beginning of the subsequent fiscal year. Projections include the populations in the former service areas of the Orange Tree Utility Company and the Florida Governmental Utility Authority, which were acquired by the CCWSD in March 2017 and March 2018 respectively. Also, in September 2018, the Board of County Commissioners approved Resolution No. 2018- 152, expanding the CCWSD’s service area to include all unincorporated areas of the county not lying within service areas granted to third parties by the Water and Sewer Regulatory Authority or as otherwise excepted by the special act that created the CCWSD. The jurisdictional boundary of the CCWSD shown in Figure 2-1 encompasses an area of high growth potential within the Rural Lands Stewardship Area known as the Northeast Service Area (NESA). The population projections in Table 3-1 include anticipated growth associated with four large developments planned in the NESA. One of these, the Town of Rural Lands West, is in the Big Cypress Stewardship District, which has the right to form its own utility, but Collier County has engaged in negotiations with the developer to provide water, wastewater, and irrigation quality water services. Population projections for the town are included in anticipation of a future interlocal agreement. Refer to the 2018 AUIR in Appendix E for further information about the population projections for the CCWSD. Per Policy 1.5 of the Capital Improvement Element of the Collier County Growth Management Plan (as of Ordinance No. 2017-21 adopted June 13, 2017), the adopted Level of Service Standard (LOSS) for the County potable water system is 150 gallons per capita per day (gpcd). All concurrency planning is based on this LOSS despite the PCUR averaging about 140 gpcd over the past 11 years, based on local water data and population estimates (129 gpcd per Table B-2 of the LWCWSP). The PCUR for the CCWSD is notably higher than those for the two other major utilities because the CCWSD service area includes a larger seasonal population, a larger commuting workforce, a higher rate of tourism, more commercial activity, and a higher proportion of customers who irrigate with potable water. The aggregate annual demand includes all these non-residential uses and is divided by the permanent population to obtain the PCUR. Note that the City of Naples has a higher PCUR than the CCWSD (281 per Table B-2 of the LWCWSP) for the same reasons. Section 3 · Population and Demand Projections 3-2 PW/6295/231366/03/01 As explained in the 2018 AUIR (Appendix E), the CCWSD evaluates required treatment capacity based upon the maximum three-day average daily demand, which is calculated using a peaking factor of 1.3, as established by the Board approved 2014 Water, Wastewater, Irrigation Quality Water and Bulk Potable Water Master Plan/CIP Plan. The max. TDADD is presented in Table 3-1 along with the AADD. Table 3-1.

Population projections were provided by the IWSD for years 2013, 2016, 2020, 2025, and 2030, and the below population data for years 2018, 2023, and 2028 were interpolated from that data. Table B-2 of the LWCWSP indicates a PCUR of 85 gpcd, and CUP No. 11-00013-W identifies 105 gpcd as the PCUR. However, the AADD projections below assume a PCUR of 75 gpcd based on data provided by the IWSD for FY 2017. Table 3-2.

Population projections were provided by AMUC for years 2016 to 2028, and the population for 2013 was extrapolated from that data. Table B-2 of the LWCWSP indicates a PCUR of 91 gpcd, and CUP No. 11-02298-W identifies 138 gpcd as the PCUR. However, the demand projections below were provided by AMUC and represent a PCUR of approximately 81 gpcd. Table 3-3.

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).

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. Section 4 · Existing Water Supply Facilities 4-9 PW/6295/231366/03/01 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. Table 4-7.

Currently, the system includes 1,604 service connections with a maximum day demand of 23 MGD. The majority of the existing customer base is golf courses, residential communities, environmental mitigation areas, county parks, and roadway medians. The demand for IQ water is seasonal, as is the available supply. Late April through early June is the critical supply/demand period. Combined wastewater flow during this period to both WRFs can be as low as 15 MGD, and can be supplemented with up to 6 MGD of groundwater, providing a total of approximately 21 MGD, leaving a shortfall of approximately 2 MGD of IQ water. There is an additional 28.5 MGD of potential demand in the service area from entities that have installed dual distribution piping. 4.1.3.1 Water Reclamation Facilities CCWSD currently operates two water reclamation facilities (WRFs). The North County Water Reclamation Facility (NCWRF) and the South County Water Reclamation Facility (SCWRF), which are shown in Figure 4-5. Table 4-8 summaries the capacities of the existing reclaimed water facilities. Table 4-8.

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 Irrigation Quality (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) for 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 as needed to meet peak demands. With both wells operational, they are expected to provide between 1 and 2 MGD of storage and recovery capacity. 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 30.47 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 Surficial Aquifer System (SAS) and Intermediate Aquifer System (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 Section 5 · Planned Water Supply Facilities 5-3 PW/6295/231366/03/01 credits in accordance with new Florida Department of Environmental Protection and SFWMD 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 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.

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. A summary of the reclaimed water storage that will be available with the expansion of the reclaimed water ASR is provided in Table 5-9. Table 5-9.

AMUC plans to add an additional reclaimed water storage ponds within the development in the future. Expansion of the facility’s capacity is planned in several phases. The utility plans to add reclaimed water storage ponds and a deep injection well system for disposal during wet weather. The new ponds will increase the Section 5 · Planned Water Supply Facilities 5-18 PW/6295/231366/03/01 storage capacity from 23.0 MG to 44.0 MG. Additionally, AMUC is currently permitting a 289 MG wetlands storage system which will be used for wet weather storage. Reclaimed water is the most important element of the AMUC Conservation Plan, presented in detail in Section 7, and will be utilized to the fullest extent possible for irrigation of the Town and University. AMUC believes it will be able to utilize 100 percent of the reclaim water generated. 6-1 PW/6295/231366/03/01 Section 6 Facilities Capacity Analysis Sections 3, 4, and 5 of this plan presented the population and associated water demand of the areas served and to be served by each utility, the existing water supply facilities in place to meet current demands, and the facilities planned to meet future water supply needs, respectively. The purpose of this section of the plan is to present a comparison of the population, water demand, facilities capacity, and permit limitations that identifies surpluses and deficits in facility and permit capacities. 6.1 Collier County Water-Sewer District (CCWSD) As described in Section 5.1, CCWSD plans to bring online a new potable water treatment facility and associated wellfield during the 10-year planning period ending in 2028. Table 6-1 illustrates how these additions to the existing system will allow CCWSD to stay ahead of the demand curve during the 10-year planning period. Table 6-1.

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.

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: In an effort to conserve water resources, the Collier County Board of Commissioners enacted the first water irrigation ordinance on September 26, 2000 with the adoption of Ordinance No. 2000- 61. Ordinance No. 2002-17, adopted on April 9, 2002, supplemented Ordinance No. 2000-61 with more restrictive irrigation hours and operational requirements. Ordinance No. 2015-27, adopted on April 28, 2015 and titled “Water Conservation Ordinance for Landscape Irrigation,” repealed and replaced the first two ordinances and provided for local implementation of the SFWMD’s mandatory year-round landscape irrigation conservation measures pursuant to Chapter 40E-24, F.A.C. The provisions of the County’s ordinance mirror the rules of the SFWMD but apply to all water resources, including IQ (reclaimed) water, which is exempt from the restricted hours of irrigation under the SFWMD’s rules. Collier County seeks to conserve their valuable IQ water supply as they do with their potable water supply. As such, the Board initiated an ASR program to allow for the storage of excess IQ water that can later be withdrawn to offset peak usage. Other water conservation measures implemented by Collier County include: Enforcing the use of low-flow plumbing fixtures pursuant to section 604.4 of the Florida Building Code, Plumbing, 6th Edition (2017); Landscaping standards in the County’s Land Development Code (LDC 4.06.00) that encourage the use of native and drought-tolerant vegetation and properly zoned irrigation systems through xeriscape; 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 water, to reduce irrigation withdrawals; Filter backwashing at the SCRWTP to eliminate water lost in cleaning filters; Section 7 · Conservation Regulations and Practices 7-2 PW/6295/231366/03/01 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 only high-use consumers. Requiring subdivisions to have separate potable and reuse water lines and prohibiting the use of County potable water for irrigation where other sources of supplemental water are permitted and available (LDC 4.03.08 C). 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. 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. 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. CCWSD has made significant strides towards improving and enhancing the efficiency of its 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 had been maintained below five percent for eight years starting with 2008, markedly lower than preceding years, but peaked again in 2017 for reasons outlined below. Four noteworthy events during the 2017 fiscal year significantly impacted the amount of unaccounted-for water loss in the CCWSD’s water distribution system. The cumulative effect of the following four events was an anomalous loss of water compared with the previous nine years: · Catastrophic impact of Hurricane Irma, which caused more than 100 water main breaks, over 400 water service breaks, and damage to numerous fire hydrants, resulting in a total loss of system pressure and nearly a complete dewatering of the distribution network, · Repeated flushing of an inactive 6-mile long 36” water transmission main, constructed in 2005, to bring it into service, · An unusually active wildfire season that required water for combatting blazes that threatened homes in the Rural Estates and along Collier Boulevard · Two large-diameter water transmission main breaks near the intersection of I-75 and Collier Boulevard Section 7 · Conservation and Practices 7-3 PW/6295/231366/03/01 Figure 7-1 CCWSD Unaccounted-for Water Loss from FY2004 to FY20181 1 The CCWSD Unaccounted-for Water Loss from FY2004 to FY2013 was taken from the 2013 Plan Update. Specific projects the CCWSD has completed 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 an additional 20 valves per year to facilitate positive and timely isolation and reduce water loss in the event of a water main break . Mapping new areas incorporated into the district, including Golden Gate City, and North East Service Area (i.e. Orange Tree Utility) to locate and record valves (and other appurtenances) in the GIS database so that water loss can be reduced by timely isolation in the event of a water main break. 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 to ensure the accurate measurement of authorized water usage accounting and billing. 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 in FY 2019. Continue utilizing a GIS-centric enterprise asset management system (Cityworks) to record the frequency of water main breaks by location and identify areas where water mains need to be programmatically replaced, reducing the potential for water loss. 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% 6.6% 0.0% 2.5% 5.0% 7.5% 10.0% 12.5% 15.0%200420052006200720082009201020112012201320142015201620172018Percentage of Unaccounted-for Water LossFiscal Year Section 7 · Conservation Regulations and Practices 7-4 PW/6295/231366/03/01 Changes made to the Utility Standards Manual require developers to provide automatic flushing devices (AFD) at dead ends and mid-points of certain looped water mains to maintain disinfectant residuals. AFDs discharge less water over time in comparison to manual flushing through fire hydrants. Collier County is actively completing water main looping projects and requires all new potable water distribution systems to be looped. Looping conserves water by eliminating dead ends which must be flushed to maintain minimum disinfectant residuals. · Collier County’s water main looping projects that have been completed over the past five years are: o Wilshire Lakes, o Tree Farm 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. Utilizing leak detection contractual services to identify leaks in older areas of the water distribution system and programmatically making repairs to reduce water loss. 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 Section 7 · Conservation and Practices 7-5 PW/6295/231366/03/01 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. 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. Section 7 · Conservation Regulations and Practices 7-6 PW/6295/231366/03/01 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. 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 Section 7 · Conservation and Practices 7-7 PW/6295/231366/03/01 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. Section 7 · Conservation Regulations and Practices 7-8 PW/6295/231366/03/01 This page intentionally left blank. 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 CCWSD’s water supply development projects identified in the Work Plan are per the update done for the 2018 AUIR. 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. PW/6295/231366/03/01 8-2 Table 8-1.

That the BCC find the Collier County Water-Sewer District Potable Water System in compliance with concurrency requirements found in FS Section 163, the Collier County Comprehensive Plan and the Land Development Code; and that it approve the proposed 2018 CCWSD Potable Water System Facilities AUIR and adopt the CIE update for FY 2018/19 - FY 2022/23. 2018 AUIR FACILITY SUMMARY POTABLE WATER SYSTEM FACILITIES CIE consistent with Board approved: FY19 budget Page 49 of 262 A. B. C. D. E. Recommendation The Public Utilities Department’s staff recommends that the Collier County Board of County Commissioners approve the 2018 CCWSD Potable Water System Treatment Facilities AUIR. Collier County Government The 2018 Potable Water System AUIR is presented as a snapshot of concurrency conditions. The CCWSD is in compliance with concurrency requirements for FY 2019 and FY 2020, as required by FS Section 163, the Collier County Comprehensive Plan, and the Land Development Code. POTABLE WATER SYSTEM - TREATMENT FACILITIES 2018 ANNUAL UPDATE AND INVENTORY REPORT (AUIR) Public Utilities Department The Public Utilities Department’s proposed 2018 Potable Water System Treatment Facilities AUIR is based on permanent population estimates and projections for the potable water service area prepared by the Collier County Comprehensive Planning Section on June 15, 2018. Populations are based on using the Bureau of Economic and Business Research (BEBR) Medium Range growth rate through 2028. Concurrency is shown for 10 years for the current service area. This conforms with the State mandated CIE, concurrency regulations, and other Collier County Departments' AUIR submittals. The Collier County Water-Sewer District (CCWSD) acquired the Golden Gate City potable water and wastewater utility systems from the Florida Governmental Utility Authority on March 1, 2018. The Public Utilities Department has solicited new master plans for water, wastewater, and irrigation quality water under RPS 18-7370, with an anticipated completion in FY 2020. To serve the current potable water service area, shown in blue in the "Current and Future Water Service Areas" map, and to support forecasted growth in the northeast region of the county, 5 MGD of new treatment capacity will be needed by FY 2028. This will be achieved through phased construction of a new regional water treatment plant at the Northeast Utility Facilities (NEUF) site. The NEUF are sited on 147 acres of County owned land at the east end of 39th Ave NE. 100% design documents were completed in 2010. The NEUF program has been reactivated, starting with updating the design criteria (FY 2018) and modifying the design plans to conform with current technologies (FY 2018-2019). To facilitate reactivation, site work is planned to begin in FY 2019. Project reactivation is in anticipation of the quantity of large developments going through different stages of the Growth Management Department review process. The need for readiness is also supported by the “Collier County Water- Sewer District System Utilization and Diminishing Capacity Report” (the “Checkbook”) which compares available treatment capacity to the quantity of Board-approved planned unit developments (PUDs). Currently, the Checkbook reports that if all active Board-approved PUDs within the current service area were to be constructed, there would be a 1% surplus in potable water treatment capacity in the regional system. INTRODUCTION On September 11, 2018, as Agenda Item 17.F, the Board adopted a resolution expanding the CCWSD's service area to coincide with the unincorporated area permitted by Chapter 2003-353, Laws of Florida. This "jurisdictional boundary"is depicted on the subsequent map entitled, "Collier County Water-Sewer District Water Service Jurisdiction," and encompasses the planned developments known as "Rural Lands West," "Winchester Lakes," and "Hogan Island Village," as depicted on the subsequent map entitled, "Future Development in Northeast Collier County." Notes The BEBR population numbers are supplemented by estimates per the implementation plan for the Golden Gate City service area, as reported in the "Technical Feasibility Study for Acquisition of FGUA Water and Wastewater Assets in Golden Gate" prepared by Stantec Consulting Services Inc., and by preliminary model results provided by Metro Forecasting Models, LLC from the Collier Interactive Growth Model for the planned developments in the expanded Northeast Service Area (i.e. Rural Lands West, Winchester Lakes, and Hogan Island Village).

New Treatment Capacity Permanent Population Served on Oct. 1. Estimates and projections for the served area were prepared by the Collier County Comprehensive Planning Section on June 15, 2018. Populations are based on the Bureau of Economic and Business Research (BEBR) Medium Range growth rate applied through 2028. Permanent population is used in accordance with the Board adopted 2014 Water, Wastewater, Irrigation Quality Water and Bulk Potable Water Master/CIP Plan. The population projections include the NE Utility WTP (formerly Orange Tree Utilities - OTU) service area beginning in FY 2018 and the Golden Gate City service area (approximately 4 square miles) beginning in FY 2019 based on acquisition dates during FY 2017 and FY 2018 respectively. The CCWSD presently supplies potable water to a population of approximately 12,404 in Golden Gate City. Based on the implementation plan outlined in the Board adopted "Technical Feasibility Study for Acquisition of FGUA Water and Wastewater Assets in Golden Gate," Phase 2 will increase the population served to 21,285 within 10 years. Required Treatment Capacity at Max. TDADD is obtained by multiplying the Permanent Population Served on Oct. 1 by 150 gallons per capita per day (gpcd) and by a maximum 3-day average daily demand (TDADD) peaking factor of 1.3 and is expressed in million gallons per day (MGD). 150 gpcd is the established Level of Service (LOS) Standard for the Potable Fiscal Year Comments and Cost Estimates Design and permitting updates for additional potable water treatment capacity at the NEUF started in FY 2018 and will be online in FY 2028, as follows: a. Update design criteria, completed FY 2018. b. Update construction drawings and bid package, $500,000 - $1,000,000, FY 2018-19. c. Construct site work, $4,000,000, FY 2019. d. Construct NERWTP potable water facilities, $71,000,000, FY 2025-28. e. Construction Engineering & Inspection, $7,500,000 estimate, FY 2025-28.

Capacity in FY 2018 increased by 0.75 MGD (as currently sited) because Orange Tree Utilities (OTU) was integrated into the CCWSD on March 1, 2017, during FY 2017. Acquisition of the Golden Gate City Utility from the Florida Governmental Utility Authority occurred on March 1, 2018. Existing Golden Gate City Utility potable water facilities include a 2.1 MGD water treatment plant; however, no additional capacity is stated because this area is now served by the nearby CCWSD regional potable water system. Unused Golden Gate City Utility assets are being repurposed and/or decommissioned, depending on condition. Twin Eagles potable water services transitioned from the NE Utility WTP (former OTU) to the CCWSD Regional potable water system on December 18, 2017. All customers within the Orange Tree PUD and the Orange Blossom Ranch PUD as well as the Corkscrew Elementary/Middle and the Palmetto Ridge High public school campuses were diverted through reliability interconnects over the course of FY 2018. Percent of Total Permitted Capacity (Max. Day) is the total maximum-day quantity of finished water produced by all treatment plants connected to the water system as a percentage of Total Permitted Treatment Capacity. Per FAC 62-555.348, source/treatment/storage capacity analysis reporting to the Department of Environmental Protection (DEP) is triggered once maximum-day demand exceeds 75% of Total Permitted Treatment Capacity, as plotted in the chart on the next page. In accordance with the Board adopted 2014 Water, Wastewater, Irrigation Quality Water and Bulk Potable Water Master/CIP Plan, Total Operational Treatment Capacity must be sufficient for the max. TDADD. Retained Operational Treatment Capacity is the Total Operational Treatment Capacity minus the Required Treatment Capacity at Max. TDADD. Total Permitted Treatment Capacity is the total permitted finished water treatment capacity at the beginning of the fiscal year in million gallons per day (MGD), including New Treatment Capacity. Total Operational Treatment Capacity is the Total Permitted Treatment Capacity less 4 MGD, the treatment capacity of a lime softening reactor/clarifier, which could be out of service during a period of peak demand, as plotted in the chart on the next page.
