Introduction The purpose of the Village of Tequesta Water Supply Facilities Work Plan (WSWP) is to identify and plan for the water supply sources and facilities needed to serve existing and new development within the local government's jurisdiction. Chapter 163, Part II, F.S., requires local governments to prepare and adopt Work Plans into their comprehensive plans within 18 months after the water management district approves a regional water supply plan or its update. The Lower East Coast Water Supply Plan Update was approved by the South Florida Water Management District (SFWMD) on February 15, 2007. Therefore, the deadline for local governments within the Lower East Coast jurisdiction to amend their comprehensive plans to adopt a Work Plan is August 15, 2008. Residents of the Village of Tequesta obtain their water directly from the Village of Tequesta Utilities Department, which is responsible for ensuring that enough capacity is available for existing and future customers. According to State guidelines, the Work Plan and the comprehensive plan amendment must address the development of traditional and alternative water supplies, bulk sales agreements and conservation and reuse programs that are necessary to serve existing and new development for at least a 10- year planning period. The Village of Tequesta Work Plan will have the same planning time schedule as ! Village's 25 -Year Comprehensive Plan. 1.1 Statutory History The Florida Legislature has enacted bills in the 2002, 2004, and 2005 sessions to address the State's water supply needs. These bills, especially Senate Bills 360 and 444 (2005 legislative session), significantly changed Chapter 163 and 373 Florida Statutes (F.S.) by strengthening the statutory links between the regional water supply plans prepared by the water management districts and the comprehensive plans prepared by local governments. In addition, these bills established the basis for improving coordination between the local land use planning and water supply planning. 1.2 Statutory Requirements Each local government must comply with the following requirements: 1. Coordinate appropriate aspects of its comprehensive plan with the appropriate water management district's regional water supply plan, [163.3177(4xa), F.S.] 2. Ensure that its future land use plan is based upon availability of adequate water supplies and public facilities and services [s.163.3177(6)(a), F.S., effective July 1, 2005]. Data and analysis demonstrating that adequate water supplies and associated public facilities will be available to meet projected growth demands must accompany all proposed Future Land Use Map amendments submitted to the Department for review. The submitted package must also include an amendment ARCADIS Project No. RF05- 108.14 1 -1 Village of Tequesta Water Supply Facilities Work Plan ARD5 Introduction to the Capital Improvements Element, if necessary, to demonstrate that adequate public facilities will be available to serve the proposed Future Land Use Map modification. 3. Ensure that adequate water supplies and facilities area available to serve new development no later than the date on which the local government anticipates issuing a certificate of occupancy and consult with the applicable water supplier prior to approving building permit, to determine whether adequate water supplies will be available to serve the development by the anticipated issuance date of the certificate of occupancy [s.163.3180 (2)(a), F.S., effective July 1, 2005]. This "water supply concurrency" is now in effect, and local governments should be complying with the requirement for all new development proposals. In addition, local governments should update their comprehensive plans and land development regulations as soon as possible to address these statutory requirements. The latest point at which the comprehensive plan must be revised to reflect the concuzrency requirements is at the time the local government adopts plan amendments to implement the recommendations of the Evaluation and Appraisal Report (EAR). 4. For local governments subject to a regional water supply plan, revise the General Sanitary Sewer, Solid Waste, Drainage, Potable Water, and Natural Groundwater Aquifer Recharge Element (the "Infrastructure Element "), within 18 months after the water management district approves an updated regional water supply plan, to: a. Identify and incorporate the alternative water supply project(s) selected by the local government from projects identified in the updated regional water supply plan, or the alternative project proposed by the local government under s. 373.0361(7), F.S. [s. 163.3177(6)(c), F.S.]; b. Identify the traditional and alternative water supply projects, bulk sales agreements, and the conservation and reuse programs necessary to meet current and future water use demands within the local government's jurisdiction [s. 163.3177(6)(c), F.S.]; and c. Include a water supply facilities work plan for at least a 10 -year planning period for constructing the public, private, and regional water supply facilities identified in the element as necessary to serve existing and new development. [s. 163.3177(6xc), F.S.] Amendments to incorporate the water supply facilities work plan into the comprehensive plan are exempt from the twice -a -year amendment limitation. [s. 163.3177(6)(c), F.S.] 5. Revise the Five -Year Schedule of Capital Improvements to include any water supply, reuse, and conservation projects and programs to be implemented during the five -year period. 6. To the extent necessary to maintain internal consistency after making changes described in Paragraph 1 through 5 above, revise the Conservation Element to assess projected water needs and sources for at least a 10 -year planning period, considering the appropriate regional water supply plan, the applicable District Water Management Plan, as well as applicable consumptive use permit(s). [s.163.3177 (6)(d), F.S.] If the established planning period of a comprehensive plan is greater than ten years, the plan must address the water supply sources necessary to meet and achieve the existing and projected water use demand for established planning period, considering the appropriate regional water supply plan. [s.163.3167 (13), F.S.] ARWIS Project No. RF05- 106.14 1 -2 Village of Tequesta Water Supply Facilities Work Plan ARC" Introduction 7. To the extent necessary to maintain internal consistency after making changes described in Paragraphs 1 through 5 above, revise the Intergovernmental Coordination Element to ensure coordination of the comprehensive plan with applicable regional water supply plans and regional water supply authorities' plans. [s. 163.3177(6)(h)1., F.S.] Address in the EAR, the extent to which the local government has implemented the Water Supply Facilities Work Plan, including the development of alternative water supplies, and determine whether the identified alternative water supply projects, traditional water supply projects, bulk sales agreements, and conservation and reuse programs are meeting local water use demands. [s.163.3191 (2x1), F.S.) ARCADIS Project No. RFW106.14 1 -3 Village of Tequesta Water Supply Facilities Work Plan ARCAM Background Information 2. Background Information 2.1 Overview The Village of Tequesta (Village) was incorporated in 1957. The Village consists of an area of approximately 2.3 square miles. The Village is bounded to the south and west by the northwest fork of the Loxahatchee River and Intracoastal Waterway, to the east by the Atlantic Ocean and to the north by Martin County, Florida. The Village boundaries are shown on Figure 2 -1. The actual service area for the Village of Tequesta extends beyond the Village boundaries to include portions of the Town of Jupiter, Jupiter Inlet Colony, portions of Martin County and unincorporated Palm Beach County, the Rolling Hills subdivision, Jupiter - Martin Utilities and Jonathan Dickinson State Park. The Village is self supplied and therefore, is the only potable water service provider within the service area. The Village owns, operates and maintains all of the raw water supply, treatment and distribution facilities located within the service area. The Village is approaching built -out conditions and will experience limited to moderate population growth through the Year 2025. Based on the U.S. Census Data, between 1990 and 2000, the Village population grew from 4,499 to 5,273, an increase of fifteen percent. Based on the population estimates prepared by the University of Florida Bureau of Economic and Business Research (BEBR), in 2006 it was estimated that the Village's population had increased to 8,179 residents. Based on the data provided by the BEBR the projected population in the Village in the Year 2025 is estimated to be 8,694. This relatively minor population growth (approximately 6 %) is reflective of the fact that the Village is substantially built -out, with future development potential and population growth limited by the scarcity of vacant and developable land. 2.2 Relevant Regional Issues As the State agency responsible for water supply in the Lower East Coast planning area, the SFWMD plays a pivotal role in resource protection, through criteria used for Consumptive Use Permitting. As pressure increased on the Everglades ecosystem resource, the Governing Board initiated rule making to limit increased allocations dependent on the Everglades system. As a result, the Regional Water Availability Rule was adopted by the Governing Board on February 15, 2007 as part of the SFWMD's water use permit program. This reduced reliance on the regional system for future water supply needs, mandates the development of alternative water supplies, and increasing conservation and reuse.

Data and Analysis 3.1 Population Information The Village's existing and future population figures are derived from Palm Beach County Planning, Zoning and Building Department and BEBR. According to the Palm Beach County Planning, Zoning and Building Department which originates from the U.S. Census Data, between 1990 and 2000, the Village population grew from 4,499 to 5,273, an increase of fifteen percent. Based on the projections prepared by BEBR and provided to ARCADIS by the South Florida Water Management District, the Village population is estimated to increase to 8,306 by Year 2010 and 8,694 by Year 2025. As previously noted, the Village's service area encompasses areas outside of the corporate boundaries. Based on the information provided by the SFWMD the population of the Village service area is estimated to increase to 12,581 by Year 2010 and 13,834 by Year 2025. 3.2 Maps of Current and Future Areas Served The Village service area currently includes the Village boundaries and extends beyond the Village boundaries to include portions of the Town of Jupiter, Jupiter Inlet Colony, portions of Martin County and unincorporated Palm Beach County, the Rolling Hills subdivision, Jupiter - Martin Utilities and Jonathan Dickinson State Park. The Village service area is not expected to experience expansion through the Year 2025. The existing and future Village service area boundaries are shown on Figure 3 -1. 3.3 Potable Water Level of Service Standard Not Applicable. 3.4 Population and Potable Water Demand Projections by Each Local Government or Utility Population served and potable water demands for the Village service area, which includes portions of the service area which are located outside of the Village boundaries, were provided to ARCADIS by the South Florida Water Management District.

The WUP allows the Village to withdraw raw water from both the surficial and Floridan aquifers. There are currently a total of ten (10) active surficial aquifer wells and three (3) active Floridan aquifer wells. There is also one existing Floridan Well (R-4) which has been installed but is not equipped or piped. The allocations also include provisions for the installation of one additional surficial aquifer well and one Floridan aquifer well at some point in the future, as warranted. A summary of the existing raw water supply wellfield's and permitted capacities based on the current WUP are provided in Table 3 -2.

Each process is operated independent of the other with the treated water from each process being blended into a final finished water product. The manganese greensand filtration process was the original treatment technology employed at the Village's WTP. The manganese greensand filtration system has a finished water capacity of 2.7 MGD and currently operates at 90% recovery. The expansion of the manganese greensand filter process in the future is not anticipated. The Village's reverse osmosis system consists of two, 1.2 MGD permeate capacity reverse osmosis process ARCADIS Project No. RF05- 106.014 34 _ I Village of Tequesta Water Supply Facilities Work Plan ARCAM Data and Analysis trains. The reverse osmosis system is designed to operate at a 75% recovery rate. However, as the membrane filtration unit's age it can be expected that the recovery rate will decrease to approximately 70% prior to membrane replacement. The Village is planning on the addition of a third 1.2 MGD permeate capacity skid in the near future. The installation of a third reverse osmosis train will increase the permeate capacity to the ultimate build -out capacity of 3.6 MGD. The expansion of the reverse osmosis treatment process will provide the Village with increased flexibility with regard to meeting the potable water demands of the service area during times of drought and water restrictions which could potentially impact the availability of raw water from the surficial aquifer. The Village distribution system consist of water mains from 4 -inch to 24 -inch diameter. The water mains vary in materials and age. The oldest mains were constructed with asbestos cement pipe and the new mains constructed with PVC or ductile iron. The distribution system includes three ground storage facilities. Two of the storage facilities are located at the water treatment plant site. These tanks have respective capacities of 2.0 MG and 0.5 MG. The third ground storage facility is located at the public works facility and has a storage capacity of 0.5 MG. System losses for the Village's distribution system are 2 -3% on an average basis. Distribution pumping facilities include high service pumps located at the Village's water treatment plant and a remote pumping station located at the Village's public work's facility. There are three high service pumps located at the water treatment plant. Two of the pumps have a design capacity of 2,275 gpm (3.28 MGD) and the third has a capacity of 1,275 gpm (1.84 MGD). The remote pumping station is also equipped with three distribution pumps. Two of pumps have a design capacity of 700 gpm (1.0 MGD) and the third pump has a design capacity of 1,000 gpm (1.44 MGD). Based on the projected potable water demands through the Year 2025 and the applicable fire flow demand the existing pumping facilities will be adequate and will not need to be modified and/or expanded. The location of the Village's water treatment plant, raw water supply wells and ground storage facilities are shown on Figure 3 -2. As of July 2007, the Village is no longer purchasing bulk quantities of finished water from the Town of Jupiter. The Village does, however, maintain two emergency interconnects with the Town of Jupiter. In the event of an emergency within either of the neighboring municipalities (Village and Town of Jupiter) the interconnects provide a means for each municipality to provide uninterrupted service to their respective potable water users. The Village is not and has no intentions to enter into any Interlocal agreements to purchase or sell bulk quantities of finished water.

The Village's water conservation plan consists of the following elements: • Permanent Irrigation Ordinance — An ordinance which restricts landscape irrigation to the hours of 4:00 p.m. to 10:00 a.m., seven days per week has been in effect for several years within the Village service area. This ordinance in addition to any irrigation restrictions imposed by the SFWIVID. • Xeriscape Ordinance — An ordinance which requires the use of xeriscape landscape principles is in effect for the Village service area. • Ultra -Low Volume Plumbing Fixture Ordinance — An ordinance which requires ultra -low volume plumbing fixtures on all new construction is in effect for the Village service area. • 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 in effect for the Village service area. • Water Conservation Rate Structure — The Village has a conservation -based rate structure which includes increasing blocks as a means of reducing demands. • Leak Detection Program — The Village has an unaccounted for water and leak detection program. The program includes water auditing procedures, in -field leak detection efforts and repair. • Water Conservation Education Program — The Village regularly distributes flyers to employees and customers. Information signs, press releases and messages regarding water conservation are also printed on customer bills. • Reuse Water — Wastewater treatment within the service area is provided by either onsite septic systems or the Loxahatchee River Environmental Control District ( ENCON). ENCON provides reuse water to several golf courses within the Village service area. A discussion of the reuse system is provided under subsequent sections of this Work Plan. 3.8 Reuse Water As mentioned above, ENCON provides irrigation quality (i.e. reuse quality) water to four golf courses located within the Village service area. The use of reuse water to irrigate these sites, which are historically ARCADIS Project No. RF05-106.014 3-7 1 Village of Tequesta Water Supply Facilities Work Plan AKAMS Data and Analysis large quantity users, significantly reduces the potable water production demand at the Village's WTP and in turn the quantity of raw water withdrawn from both the surficial and Floridan aquifer. A summary of the reuse application sites and the allotted daily usage at each site is shown in Table 3-4. Table 3-4: VOT - Reuse Application Sites and Allotted Usages Reuse Application Site Daily Allocation (MGD) Jupiter Hills Country Club 1.10 Turtle Creek Golf Course 0.55 Tequesta Country Club 0.50 Riverbend Golf Course 0.40 Total: 2.55 Based on discussions with ENCON, there are currently no plans to expand or add additional reuse application sites within the Village service area. Furthermore, the current daily allocations provided to each site appear to be sufficient to meet the needs of each of the existing reuse application sites, therefore an increase in the allocations at each site is also not anticipated. Since the application of reuse water for irrigation has been ongoing within the Village service area for a number of years the projected potable water demands of the service area have been developed exclusive of the required irrigation demand at each of the applications sites. if in the future, there is additional reuse demand within the Village service area and reuse water quantities are available, the potable water demand projections of the service area would be updated to reflect the expansion of the reuse system. A reuse service map showing the layout of the reuse application sites within the Village service area is provided as Figure 3 -3. ARGADIS Project N0. RF05- 106.014 3-8 C? LL.

Capital Improvements 4.1 Work Plan Projects and Schedule As part of the preparation of the Water Supply Facilities Work Plan, local governments which are self - supplied are required to evaluate the existing community water system and determine what improvements, r if any, will be required to the existing treatment systems and/or distribution infrastructure to meet the potable water demands of the service area over the projection duration. The Village has completed an evaluation of the current system and infrastructure based on the projected potable water demands of the Village service area over the next 25 years. The projects identified will be essential to the Village meeting the potable water demands of the service area. It should be noted that the projects anticipated within the next five years are consistent with the projects identified in Appendix A of the SFWMD LEC Plan Update. The following work plan projects are anticipated within the next five years and will be incorporated into the Village's capital improvement plan (CIP): • Expansion of the reverse osmosis treatment system at the Village's WTP. The expansion will include the installation of a third, 1.2 MGD permeate capacity R.O. skid, which will increase the total permeate capacity of the plant to 3.6 MGD. • The installation of the wellhead piping and appurtenances at the previously installed Floridan aquifer well designated R-4_ The installation of a third R.O. process train will necessitate the equipping of the well to provide redundancy of the Floridan raw water supply wells. This project will also include the installation of the associated raw water main. The following work plan projects are anticipated sometime in the future and will be incorporated into the Village's CIP, when warranted: 0 The installation of a fifth Floridan aquifer well to be designated R -5. R.O. well R -5 will be installed, as required, to supplement the existing Floridan wells and provide redundancy and increased flexibility. • The installation of an eleventh surficial aquifer well to be designated Well No. 28. Surficial Well No. 28 will be installed, as required, to supplement the existing surficial wells and provide redundancy and increased flexibility. ARCADIS Project No. RF05. 106.014 ¢1 I 5. Summary and Conclusions 5.1 Raw Water Supply vs. Projected Potable Water Demand As previously discussed, the potable water demand projection data is based on the data provided to us by the SFWMD. It should be noted that an evaluation of the data provided by the SFWMD with current operating data indicates that data provided is consistent with the current population increase and per capita water usage within the Village's service area.

Therefore the maximum production capacity of the filter plant is actually 2.43 MGD based on a design recovery rate of 90%. z fo retain flexibility, operate more cost efficiently and maintain water quality the Village will meet the potable water demands by producing 60% of the required finished water using the manganese greensand filtration plant and the balance (40% demand) using the reverse osmosis system. The data represents this standard operating scenario. The surplus values indicated are inclusive of all of the raw water supply wells (surficial and Floridan) included within the WUP. As such, these values may be slightly inflated due to the inclusion of redundant wells. Nevertheless, even with the deletion of the well with the highest permitted withdraw capacity in both the surficial and Floridan wells the resulting raw water production capacity still results in a surplus in the total raw water production capacity when compared to the potable water production capacity in each of the projection years. ; Data represents raw water surplus based on meeting the annual average demands of the service area using the reverse osmosis membrane softening plant exclusively. However, to maintain water quality and operate efficiently the standard operating procedure will be as outlined in #2 above. A review of the data shown in Table 5 -1 indicates that the Village will be capable of meeting the potable water demands of the service area through the Year 2025. It should be noted that the data presented includes, where applicable, the proposed capital improvement projects to be completed in accordance with the schedule provided in Section 4. 5.2 Comprehensive Plan Amendment - Goals, Objectives and Policies The following objectives and policies are being adopted through an amendment to the Village's Comprehensive Plan in conjunction with elements proposed and to be implemented as part of the Village's 10 -Year Water Supply Facilities Work Plan as previously discussed.
