City of Port Orchard Patti Kirkpatrick City Clerk Publish: Port Orchard Independent April 23, 2010 4 � CITY OF PORT ORCHARD �. '. 2009� �.f ` WATER SYSTEM PLAN.!, Prepared By. - �, Iz PACE Engineers Inc. —� ' _- l ' / j .� EXECUTIVE SUMMARY The City of Port Orchard's 2009 Comprehensive Water System Plan represents a compilation of planning and engineering studies completed by PACE Engineers, Inc. The purpose of the Plan is to determine the adequacy of the City of Port Orchard's existing water system(s) to meet the existing and projected needs of the community it serves. The Plan puts forth a long-range planning document that addresses the regulations and concerns associated with operating the two public water systems that serve the retail service area designated in the Kitsap County Coordinated Water System Plan. The two water systems are referred to as the "City" System and the "McCormick Woods System throughout this Plan. Although they are both owned and operated by the City of Port Orchard under one combined water utility, the two systems each have unique water system identification numbers assigned by the State Department of Health and the US Environmental Protection Agency. A primary goal of the water utility is to physically connect the two systems with the requisite transmission, pumping and pressure reducing facilities. This Plan puts forth a program for doing that as a means of maximizing existing and proposed sources of supply, increasing the reliability of both systems and simplifying the compliance and regulatory requirements of operating the system independently. The 2009 Water System Plan supersedes and updates the City's current water plan, the Water System Plan for the McCormick Woods system and any previous drafts of this document. This document has been prepared in accordance with the rules and regulations governing the operation of public water systems as administered by the State of Washington Departments of Health and Ecology, Kitsap County, and the codes and policies of the City of Port Orchard. History and Location The City of Port Orchard is located on the Kitsap Peninsula of Washington State along the southern shore of Sinclair Inlet on the Puget Sound. The City is south of the City of Bremerton and from downtown Port Orchard, one can look north across the inlet to the Puget Sound Naval Shipyards. The study area for this planning document is the City's of Port Orchard's water service area as put forth in the Kitsap County Coordinated Water System Plan. The 15.5 square mile service area includes the majority of the current city limits, as well as the recently annexed community of McCormick Woods in the western portion of the service area. While the City maintains service to the majority of its residents and a variety of commercial and governmental activities within the city limits, the West Sound Utility District serves a small area in the eastern portion of the City. The West Sound water system abuts and is intertied with the Port Orchard system in several locations. The City of Port Orchard took over the McCormick Woods system and has owned and City of Port Orchard 2009 Comprehensive Water System Plan operated it since 1988 as a remote and self sufficient system. Service to existing McCormick Woods development and future development in the area and connection to the main Port Orchard water system is contemplated in this Plan. Expansion of the retail service area beyond the area established in the Kitsap County Coordinated Water System Plan is limited to any potential service area exchange negotiations between the City and neighboring purveyors and/or expansions associated with annexations to the City of Port Orchard's corporate limits. Land Use, Population and Employment The majority of the service area is designated for varying densities of residential uses and supporting commercial activities, with the highest concentration of density and development occurring in the downtown area and newer residential construction occurring in the area south of Tremont Street. The southern part of the service area is characterized by more rural development. As part of the planning process, the current population and employment within the city limits and ultimate water service area were estimated and Equivalent Residential Units (ERU's) were determined. As previously noted, the City does not currently serve the entire city limits or the entire service area. An estimated population of 8,550 people, or approximately 5800 ERU's, are currently served by the two city systems. As noted earlier, the City does not currently serve the entire water service area or the entire city limits. Population and employment is expected to increase significantly within the long-term 20 year planning horizon. Water Demands Identification of historical and projected water system demands is a critical element of the planning process. In 2008, total water production was approximately 375 million gallons, while sales were approximately 334 million gallons with average day demands of approximately 0.9 million gallons per day. Water use per ERU differs between the two water systems, averaging approximately 165 gallons per day for the City system and 260 gallons per day for the McCormick System. While these numbers are considered typical for the type of developments served by each system, it is believed that the McCormick Woods use per ERU may be skewed by unaccounted for irrigation uses and reservoir overflows that have since been curtailed. The City looks forward to obtaining more accurate and detailed water system use data as part of its compliance with Water Use Efficiency requirements. Using the same estimated use per capita to provide a conservative estimate of future water supply requirements, water demand by 2030 would be approximately 2 million gallons per day. A summary of the total water use by customer class is illustrated below. The City is currently processing additional water rights to support needed well source production beyond the 20 year planning period. Source production has recently declined due to decreasing yields from existing groundwater wells. While total water rights, as documented in recent approval of Well 10 water rights, together with pending water Executive Summary /\\\ ///\ Page III City of Port Orchard 2009 Comprehensive Water System Plan rights, the physical ability to withdraw water and deliver adequate flows to to all areas of the service area are limited. This Plan outlines the improvements required to support new development in the western portion of the service area through interconnection of the two systems. This is expected to occur as part of the proposals to develop the Glenwood JPA that lies between the City system and the McCormick Woods system. It is important to note that population/employment growth will at some future point be dependent on the ability to meet water demands. The source improvements identified in this plan are critical to the City's ability to support the levels of growth projected for the existing service area.

The City System includes the older portions of the City along the waterfront as well as the more rapidly developing uplands. The area currently served by the Port Orchard system is generally bounded by the waterfront on the north, Sedgwick Road in the vicinity of State Highway 16 on the south, Anderson Hill Road on the west and West Sound Utility District on the east. The system consists of three pressure zones: Low, High, and Intermediate (at hydraulic gradelines of 260, 390, and 336 respectively) to regulate pressure within the community. The Low Zone (260 Zone)is extends from sea level to an approximate maximum service elevation of 200 feet and serves approximately 45% of the existing population and employment base served by the Port Orchard System at a hydraulic grade line of 260 feet. The Low Zone is fed primarily by Wells 6 and 7 but can receive backup supply from a wholesale meter connection to the City of Bremerton system west of the City and through a PRV from the Port Orchard High Zone. Approximately 2.15 million gallons of storage in the Low Zone is provided in Morton Street Standpipe, Park Reservoir, and Maple Street Elevated Tank. The High Zone (390 Zone) of the Port Orchard system serves approximately 55% of current connections and covers the residential uplands in the southern portion of the City and commercial area in the east. Ground elevations within the High Zone range from approximately 210 feet to approximately 330 feet. The High Zone is primarily fed by Wells 8 and 9 located at the Van Zee Park site, although additional supply can also be received from the City wells or Bremerton supply in the Low Zone via the Melcher Street Pump Station. The High Zone operates at a hydraulic grade elevation of 390 feet and approximately 2.1 million gallons of storage in this zone are provided in the Old Clifton, Sedgwick, and South Sidney reservoirs. To improve pressures in the higher elevations of the City lying east of Blackjack Creek the High Zone was expanded in 1983 with a 12-inch main across the creek. Interties with West Sound Utility System in this area, as well as the ability to revert back to serving the area from the Low Zone, provide the necessary reliability for the isolated portion of the High Zone. A new intertie to the West Sound water system was constructed in 2006 and provides a backup source to the southernmost reaches, and is located on the 1 million gallon Sedgwick Reservoir. The Intermediate Zone (336 Zone) was created in 1984 to provide satisfactory water pressure to a small area north of Kendall Street in the vicinity of Harrison Avenue. The Zone is supplied by a PRV from the High Zone and storage is provided from the High Zone. Because the Intermediate Zone is so small, it has been considered as a sub -zone to the High Zone. Executive Summary /\ /\ Page v City of Port Orchard 2009 Comprehensive Water System Plan The McCormick Woods (or 580) System area consists of the 580 Zone and is currently not connected to the City's system. It has its own source and storage and an intertie with Bremerton augments supply to the area. As noted in Section 6, the agreement with Bremerton is complicated by the City of Bremerton's lack of storage in the area and provisions in the agreement that prohibit introduction of fluoride into the 580 zone until separate storage is constructed by Bremerton. The recommendations of this Plan include projects that will intertie the 580 Zone and City systems, eliminating dependence on Bremerton for water supply and allowing for isolation of the two systems and Bremerton's issues with Port Orchard policies for fluoridation of water. Water System Analysis Analysis of the existing systems was completed to determine the requirements for the orderly expansion of and improvements to the City and McCormick Systems as well as service to the Glenwood JPA that lies between the two systems. The primary focus of the analysis is on evaluation of existing facilities to meet the projected needs of the anticipated population of the service area. For large scale and costly facilities such as source of supply, transmission lines and storage reservoirs, that means addressing the ultimate service area needs to ensure that any improvements to this type of general facilities will be of sufficient capacity and location to meet needs well in the future. For distribution system facilities, the primary goal was to develop a more detailed program for upsizing to meet the fire flow requirements, and the regular renewal and replacements required as part of an asset management program to protect the investment of ratepayers to the system. Identification of facilities required to connect the main City System with the McCormick Woods System, and the general network of piping to bring City water service to the south and western portions of the service area are also discussed. The City of Port Orchard has water rights for a total of nine groundwater wells, six within the Port Orchard system and three serving the McCormick Woods area. Water rights are currently being finalized for Well No. 10, a new groundwater well to augment supply to the Port Orchard system. Also, the City has made application to consolidate water rights for McCormick Woods Wells 1, 2, and 3. By bringing the new deep aquifer well (Well 11) online, the City will increase its water rights from 600 to 750 gpm at this location. Well No. 10 was drilled in 2006 and it appears that the well will yield more than 1,500 gallon per minute, possibly up to 2000 gpm, of high quality water that will require minimal treatment. As a result, the City has requested water rights be increased from 500 gpm to 1500 gpm. A permit for this request is currently pending. This additional capacity will augment supply from the existing City wells, some of which are experiencing declining yields and help support the anticipated population of the Port Orchard System. Construction of Well 10 itself along with treatment, and transmission pipeline to connect the new well to the 390/260 zones is required to bring Well 10 on line and is detailed in the CIP presented in Section 7. The remote location of the well at the far (^�wAC Executive Summary PA Page vi City of Port Orchard 2009 Comprehensive Water System Plan eastern edge of the City will necessitate a new transmission line from east to west to transfer the water to where it is needed. Several alternatives for routing transmission mains and locating the required treatment facility have been identified in a separate Well 10 Engineering Report completed in 2009. One alternative includes delivering raw water form Well 10 to the Well 6 site for treatment. This alternative provides a solution to the much needed upgrade of the Well 6 equipment and facilities by constructing on new treatment faicity to accommodate water from both wells. Additional transmission and pumping will also be required to deliver water to the southern portion of the service area, in the vicinity of the Glenwood JPA. This work, coupled with a pumping and PRV station will ultimately allow for water transfer between the main City system and the McCormick Woods area. Growth projection for the Glenwood JPA and McCormick Woods West have been included in the ultimate service area projections used for Well 10 water rights applications. The City has also made a water right application to formally recognize a withdrawal that has been part of the Port Orchard water supply since early in the City's history. Well 5, an old artesian flowing well, has reached a point of disrepair that makes it unsuitable as a source. When considering moving the roughly 50 gallon per minute production to nearby Well 4, it was discovered that the City had never registered Well 5 with the Department of Ecology, and did not have the water right that it had presumed it had. The application for 50 gpm is intended to rectify that long -ago oversight. The City has experienced taste and odor issues associated with hydrogen sulfide in some of its groundwater wells. This issue has historically been addressed by the use of stilling basins which assist with dissipation of the hydrogen sulfide and additionally, provide required chlorine contact time. As discussed below, the City's City Hall Pump Station is equipped with these basins and it is recommended that the City consider alternative treatment methods at the time that pump station is either updated or relocated as part of regular renewal and replacements. The only other anticipated water quality improvements is the possibility of additional rechlorination facilities to ensure that adequate levels of chlorine residual are maintained in the outermost reaches of the system. Additional recommendations on this are expected as the results from federally mandated elevated chlorine residual monitoring become available. Water Quality Monitoring program information is provided in Appendix E. The three pump stations serving the City System are of adequate capacity to meet near term demand requirements, although the Melcher Street Pump Station may require upsizing at some future date beyond the six year planning horizon, depending on how service is provided to the southern portion of the service area. The Melcher Station is also in need of upgrade in the near future to replace certain equipment and modernize the station. As discussed above, the City Hall Station will require abandonment or a significant upgrade with new piping, pumps, and associated controls within the six year planning horizon unless this station is abandoned and replaced with a new station at Well 7. Consideration of relocation of the pump station may be warranted based Executive Summary C /\ Page vii City of Port Orchard 2009 Comprehensive Water System Plan on the quantity and quality of water from the proposed Well 10 and a specific engineering report addressing transmission and pumping of water from Well 10 will be required based on the yields from the new facility. Consideration of hydrogen sulfide dissipation and chlorine contact times provided by the existing pump station configuration will be important considerations when evaluating relocation of the pump station. The third station is located at Well 6 and as mentioned previously, the Well 6 site, equipment and facilities are all in need of significant upgrades which could be accomplished with the construction of a centralized treatment plant at that site. Currently only one pump station serves the McCormick Woods System and that facility pumps water from the source and associated small storage reservoirs to the 580 zone tank. The 580 Pump Station is of adequate capacity to meet the immediate service area needs of that development and now improvements are contemplated in the near term six -year planning period. Evaluation of the City's five storage reservoirs serving the City System was conducted to ensure that adequate storage is available to provide for equalizing storage as well as both standby and fire suppression storage. A slight deficit in High Zone Storage was identified under current conditions and through the planning horizon of 2025. Consideration of a small -pressurized zone to serve the high elevation immediately surrounding the Sedgwick Tank would rectify the problem by making more water in existing tanks available under emergency conditions, reducing dead storage quantity. Automatic interties with pressure reducing valves from the High Zone to the Low Zone are also recommended to improve system reliability and the availability of standby storage to the low zone for operational flexibility. A storage deficit shown for the 580 Zone and Glenwood JPA area is anticipated due to development of McCormick Woods West and the Glenwood JPA. A new 1.3 million gallon reservoir is proposed to satisfy the needs of the 580 zone. Any additional storage required as part of any development proposals in the area and will be financed by developers or future connection charge revenue. Additional source of water will also be needed for the continued growth in this area. A plan to supply the 580 Zone and higher zones in the area through and interconnection with the City System in the vicinity of the Glenwood JPA is put forth as the most cost effective and efficient solution to meeting long term supply needs of the entire service area. This is somewhat complicated by the fact that Bremerton water is not fluoridated and either an amendment to the existing interlocal agreement prohibiting fluoridation or an alternate source of supply would be required to prevent mixing. Section 6 provides a detailed description of the proposal for interconnecting the two systems and as noted therein, development of the Glenwood JPA will require the referenced interconnection. A computerized system model was constructed and used to evaluate the transmission and distribution systems and determine areas where system deficiencies exist, or are likely to develop, under various flow conditions. These deficiencies include areas of high or low pressure, areas with high flow velocities in the pipelines, and areas with low available fire flow. �.a Executive Summary \ri\vC Page vill City of Port Orchard 2009 Comprehensive Water System Plan In most areas, the water system is sufficient to handle ADD and MDD flows through 2030 while generally maintaining working pressures above 40 psi. Pressures below 40 psi exist at higher elevations near tanks as to be expected, and in isolated areas of small mains in the distribution system and the Melcher Pump Station feed line. Consideration of a small constant pressure booster station to serve the high elevations immediately surrounding the 1.0 million gallon Sedgewick reservoir may be warranted. This will allow for better circulation of water in the reservoir through increasing the operational range and decreasing the unused volume of the tank. These areas become problems in fire flow events and construction of larger diameter mains as discussed below will alleviate the deficiencies. Based on computer model results confirmed by operator information, a significant water main replacement program has been identified to meet minimum fire flow requirements at the State mandated minimum pressures, replace undersized pipes and take a proactive approach to regular system renewal replacements and avoid catastrophic failure of aging and under capacity lines. The first and highest priority water main replacement project is for replacement of the smaller diameter mains in the downtown area of the of the low pressure zone. High priority Low Zone distribution system improvements are recommended for completion within the six year planning horizon. Following that, smaller diameter mains in the eastern and southern portions of the high pressure zone will need to be addressed. Some of these improvements may be accomplished by developer extensions. Summary of Limiting Factors The biggest challenge facing the City of Port Orchard is meeting the needs of future development while maintaining sufficient yield from its permitted supply. While water rights are sufficient to meet both near and long terms needs of the City, the ability to withdraw, treat and supply water is currently limited. Construction of Well 10 supply, treatment and transmission is critical to alleviating the declining supply yields from existing wells. Consideration of additional water rights at and/or transfer of rights to Well 10 may become equally important if yields from other wells continue to decrease. Another critical consideration for operating and regulatory simplification is combining the two water systems into one system. While construction of additional storage and continued use of the Bremerton supply to 580 Zone provides an interim solution, development of the Glenwood JPA cannot occur without an intertie between the City and McCormick Systems. This will bring additional supply to 580 Zone, allow for integration of the systems, provide operating independence, improve reliability and reduce paperwork, testing and confusion associated with operating under two separate water system Identification numbers. � Executive Summary \ Ri6E Page ix City of Port Orchard 2009 Comprehensive Water System Plan Lastly, portions of the City Water System will soon approach the end of their useful life. Funding for needed upgrades and replacement of the aging water infrastructure is needed to improve fire flows, replace undersized mains and take a proactive approach to renewals and replacements prior to more costly replacements following facility failure. An aggressive approach to acquiring funding from current Economic Recovery program grants, low interest bonds or low interest loans is recommended and discussed further in Section 10. Capital Improvement Plan The total capital improvement plan for identified water system upgrades totals approximately $24 million dollars (at present value). Of that amount, approximately $17.6 million has been identified as high priority items for the six -year planning horizon. Projects which would could be financed by growth charges (connection charge) include construction of Well 10 and Well 11 and associated transmission improvements, construction of a new reservoir in the 580 Zone, interconnection of the two water systems, installation of pressure reducing valves between the High and Low Zones, and rehabilitation or replacement of the City Hall pump station. The amount of water improvements that can be constructed over the next 6 year period will depend on funding. It is recommended that the City fund the suggested improvements in the following manner. First, any grants or low interest loans should be utilized to finance needed projects. Next, cash on hand from connection charges, rates and any other sources of money should be utilized. Any short -fall in these funding sources required to finance the required system improvements may be obtained from selling revenue bonds or securing low interest loans from the State. Loan funding and Bond issues, however, must consider available funding for repayment. Based on this comprehensive plan and a subsequent rate study also by PACE Engineers, Inc., existing rates and charges were increased sufficient to cover projected City costs or needed improvements to the system at that time. Rates were again adjusted in 2009 to fund operation costs and accommodate current revenue projections following annexation of the McCormick Woods area. The City of Port Orchard's Municipal Water Code, which includes current rates and charges has been included as the last element of Appendix E. Another key element of recent rate reviews was implementation of a strong conservation program through rate incentives for stewardship of water resources and compliance with recently implemented municipal water laws requiring water conservation. In addition, updated connection charges were recommended and implemented. It is recommended that after this Comprehensive Plan is adopted, the City's connection charges be reviewed again and updated to include all CIP recommendations at current project budgets. Rates and charges should be reviewed yearly to confirm they are adequate to meet all Water Department requirements. /i���Executive Summary \ RCO Page x City of Port Orchard 2009 Water System Plan PROJECT CERTIFICATHON The technical material and data contained in this report was prepared by PACE Engineers, Inc. under the supervision of the below listed individuals.

Table of Contents l PACE Page and CITY OF PORT ORCHARD 2009 WATER SYSTEM PLAN City of Port Orchard Public Works Department 216 Prospect Street Port Orchard, Washington 360-876-4991 Mayor Lary Coppola Public Works Director Mark Dorsey, P.E. Prepared By: P=G / PACE Engineers, Inc. 1601 Second Avenue Suite 1000 Seattle, Washington, 98101 SECTION 1 INTRODUCTION 1.1 INTRODUCTION The City of Port Orchard is located on the Kitsap Peninsula of Washington State. The City's water system consists of two separate water systems owned and operated by the City of Port Orchard: the City system serving the majority of the City limits, and; the McCormick Woods system serving the recently annexed McCormick Woods area in the western portion of the City. Collectively the two systems served a total of approximately 5,800 Equivalent Residential Units (ERUs) in 2008 with nearly 5,000 ERUs in the City system and just over 800 ERUs in the McCormick Woods system. The general location of Port Orchard is shown on Figure 1-1. Port Orchard is a Group A public water system. Under Washington State Law (WAC246-290) all Group A water systems (those serving 1,000 or more services) are required have a comprehensive water system plan approved by the State Department of Health and other agencies having jurisdictions, and adopted by the water system. Comprehensive water system plan updates are required to occur at least every six years. This document represents the City of Port Orchard's most recent water system planning effort and updates and supersedes the City's 1995 Comprehensive Water System Plan and 2003 Water System Plan Amendment regarding the McCormick Woods area of the water service area. As demonstrated later in this section and throughout the Plan, a variety of other planning efforts, including land use planning by the City and others and coordinated water system planning for the region, were utilized in the development of this document. In accordance with State Department of Health requirements, this document: • Identifies and describes the retail water service area; • Provides a summary of historical and projected water use within the system; • Describes the existing water system serving the two systems (City System and McCormick Woods System) that are owned, operated and maintained by the City. Establishes minimum design criteria for evaluation of the water system(s); • Identifies system deficiencies and presents a detailed capital facilities plan; • Provides an implementation plan for the recommendations contained herein, and; • Complies with all appropriate regulations regarding the Kitsap County Coordinated Water System Plan, the Municipal Water Law and the State Environmental Policy Act A computerized hydraulic water system model was developed to facilitate a complete evaluation of the water system and simulate alternatives for recommended water system improvements. The City's electronic mapping has also been updated in conjunction with this water system plan update and has been coordinated with Geographic Information System (GIS) mapping provided by Kitsap County. 6 Introduction 6111\ Page 1-7 City of Port Orchard 2009 Water System Plan 1.2 AUTHORIZATION In 2005 the City of Port Orchard acknowledged the need to update the 1995 Comprehensive Water System Plan and subsequent amendments and authorized PACE Engineers, Inc. (formerly known as Penhallegon Associates Consulting Engineers, Inc.) to prepare this document in accordance with all applicable rules and regulations and with the City's existing code, policies and procedures. 1.3 GOALS AND OBJECTIVES A variety of goals and objectives guide the operation of the City of Port Orchard's public water system. These goals and objectives are in addition to the policy statements put forth in Section 2 of this Plan. They have been verified and utilized in the evaluation of the water system and development of this Plan and are summarized as follows: • Maintain drinking water quality in accordance with State and Federal standards to insure the quality of drinking water delivered to customers of the water system; • Provide high quality domestic and fire protection service to all areas within the retail service area. • Utilize City owned and operated sources of supply to maximize efficiency and cost effectiveness of the water system. • Maintain water system facilities to ensure a high level of service is provided to all customers and maximize the life of facilities to protect the investment of ratepayers. • Construct new facilities as required to serve the existing and future populations of the established water service area and City of Port Orchard Urban Growth Area. • Develop a long range program for interconnecting the City's main water system with the independent facilities serving the City's 580 and 660 Pressure Zones (McCormick Wood System). This will allow for combining the two existing systems under one water system identification number. • Implement and maintain water use efficiency and conservation programs to discourage water waste, promote the prudent use of water resources and support protection of habitat and the environment. • Work with neighboring water utilities, participate in regional water planning efforts to establish common goals of uniform water system standards and facilitate coordination of efforts toward the adequate provision of water service throughout the region. • Conduct water system operations in a manner that insures high quality service in accordance with all applicable rules and regulations, at the lowest reasonable cost.

This Plan represents the consolidation and update of two separate planning documents for the Port Orchard Water System: the City of Port Orchard 1995 Comprehensive Water System Plan and 2003 Water Comprehensive Plan Amendment. The planning process has been based on 2008 conditions and projected needs throughout the water service area through 2030. As development within the service area occurs, modifications to the recommendations of the Plan may be required. Significant changes, such as a change in the water service area, may require a plan amendment to accurately reflect the future needs of the City and keep neighboring jurisdiction informed of those needs. Changes in the Capital Improvement Plan schedule, however, may occur from time to time as actual development dictates the exact need and location for water system improvements, extensions and facilities, and as the City reviews its capital improvement needs in relation to available funds and project priorities. These minor changes are anticipated and are not expected to require Plan amendment. Instead, these changes are anticipated as part of the City's annual budgeting process. The overall objective of this study is to establish a comprehensive water system plan for the City of Port Orchard that provides for routine maintenance and the orderly development of water system facilities in a manner that meets the needs of existing and future customers of the City's system as well as the requirements of all applicable regulations governing operation of a public water supply. The process used to meet this objective is summarized by the following activities: Presentation of descriptions and characteristics of the water service area, land use and population, water consumption trends, and water system features and characteristics; • Identification of minimum design criteria and construction of a hydraulic computer model for the purpose of evaluating the existing source, storage and pumping facilities, and the distribution system's capabilities to meet existing and projected system demands; • Identification of existing and projected water system deficiencies, alternatives for improvements, and recommendations for system improvements; • Evaluation of City owned sources of supply and intertie connections and development of a comprehensive water supply strategy that ensures adequate supply for projected development conditions as well as water resource management. Key considerations include water quality monitoring, watershed protection, water use efficiency and water shortage response. • Presentation of a detailed capital improvement program and implementation plan, including project cost estimates and proposed project sequencing, scheduling and financing. Introduction (\ 111\ Page 7-5 City of Port Orchard 2009 Water System Plan • Completion of an environmental checklist considering the environmental ramifications of implementing the Plan and issuance of a State Environmental Policy Act (SEPA) Determination. 11.5 OVERVIEW OF THE CITY 1.5.1 Location and History The City of Port Orchard is located in Kitsap County, Washington along the shoreline of Sinclair Inlet on the Puget Sound. The City is south of the City of Bremerton and from downtown Port Orchard, one can look directly north across the inlet at the Puget Sound Naval Shipyards. Port Orchard was the first city in Kitsap County and was incorporated in 1890 under its original name of Sidney. The city was renamed in 1903 to Port Orchard. The first water system components were installed in 1911. The City of Port Orchard has grown to a vibrant waterfront community with a variety of commercial and governmental activity as well as a strong residential community. The area has experienced significant growth in more recent years, and serves in part as a bedroom community to naval shipyard employees and residents that commute by ferry to downtown Seattle for employment. 1.5.2 Overview of Existing Water System The water system has grown right along with the City and the majority of existing pipe was installed in the 1960's. Additional wells and other general facilities have been constructed to accommodate the growing population and keep up with the ever increasing regulations associated with operating a public water system. A network of approximately 47 miles of water pipe, six active groundwater wells and six storage reservoirs serve what is referred to in this Plan as the "Port Orchard system" and serves the majority of the City. A small portion of the City is served by the West Sound Utility District (formerly known as Annapolis Water District), whose service area lies east of Port Orchard and includes portions of the City's eastern potential annexation, or urban growth area. Emergency interties with the Annapolis Water System are detailed in Section4. An independent system referred to as McCormick Water Company was constructed in the late 1980's to serve a residential community within 1300 acres known as the McCormick Woods Planned Unit Development (PUD). The City assumed the McCormick Woods Water Company in 1998 and the area was annexed in 2009. The McCormick Woods System currently consists of the 580 Pressure Zone serving the McCormick Woods development and is planned for expansion to serve additional development in the western portion of the City. The area system is supplied by groundwater wells, three storage reservoirs, a network of distribution mains and a 16-inch transmission main from the supply site to a recently constructed 450,000 gallon reservoir. Approximately 11 miles of 6 to 12-inch pipe serve the area. As detailed in Section 4, alternate, temporary back-up Page 1.6 City of Port Orchard 2009 Water System Plan supply to the area is available from an intertie with the City of Bremerton located near the entrance to the development that was constructed in 2006. 1.6 RULES AND REGULATIONS As a public water system, the City of Port Orchard operates under the requirements of WAC 246- 290 and in accordance with a myriad of regulations pertaining to the production and delivery of safe drinking water for the purpose of public consumption and fire protection. A brief summary of the primary rules and regulations effecting operation of the water utility is presented below. 1.6.1 Federal Regulations 1.6.1.1 Safe Drinking Water Act Public Law 93-523, the Safe Drinking Water Act (SDWA), directs the U.S. Environmental Protection Agency (EPA) to establish minimum national drinking water standards limiting the amount of various substances that may be present in drinking water sources. These limits are regulated by the State of Washington Department of Health and adhered to by the City. Complete details of current regulations and the City's water quality monitoring program are provided in Section 8 of this Plan. 1.6.1.2 Clean Water Act The Clean Water Act puts forth regulations and requirements for restoration and maintenance of the integrity of the nations waters in terms of physical, chemical and biological characteristics. The U.S. Environmental Protection Agency is the primary administrator of the Clean Water Act but has delegated many aspects of administration of it to the State of Washington Department of Ecology (DOE). 1.6.1.3 Endangered Species Act Because of the listing of the Puget Sound Chinook Salmon and Bull Trout as "threatened species", rules and regulations under the authority of the Endangered Species Act (ESA) impact the City's water and sewer systems operations. The City administers and complies with all permit requirements associated with construction of its utility systems and exercises the most current techniques in system design, construction, operation and maintenance to reduce the threat of impacting endangered species. 1.6.2 State of Washington Requirements 1.6.2.1 Washington Administrative Code / Revised Code of Washington The rules and regulations regarding public water supplies are a part of the Washington Administrative Code (WAC) and are adopted pursuant to the ..� Introduction \ 9"'ACE Page 1.7 City of Port Orchard 2009 Water System I provisions in the Revised Code of Washington (RCW) 43.20.050 for the protection of public health. They provide the minimum standards for design, construction, operations and maintenance of public water systems in conformance with the Safe Drinking Water Act of 1974 and all subsequent amendments thereto. 1.6.2.2 Growth Management Act The Growth Management Act (RCW 36.70A) has a direct impact on utility system planning by requiring a complete inventory of existing system facilities and a comprehensive effort toward determining the capability of utility systems to support anticipated growth. A primary outcome of the growth management planning is the delineation of an Urban Growth Area (UGA) boundary within which an urban level of service is required. The City of Port Orchard's water service area includes areas within established UGA and Rural Areas. Although public water service is permitted within the designated rural area, future development of the water system must be appropriate for and consistent with GMA land use designations. 1.6.2.3 State Environmental Policy Act State Environmental Policy Act (SEPA) review is generally required for all water system projects other than regular renewal and replacement projects involving pipe sizes of less than 10-inches. SEPA requirements and exemptions are detailed in WAC Chapter 197-11 and adopted City environmental policies are in place to insure that environmental concerns associated with construction are adequately addressed. Initiation of the SEPA process can be at the City's direction or as required for various permits. 1.6.2.4 Department of Health Approval of this document and operation of the water system is under the jurisdiction of the Washington State Department of Health (DOH). This document has been prepared, and the water system is operated, in accordance with the requirements set forth in the DOH "Water System Design Manual" (August 2001). This document incorporates the policies, guidelines, and practices of the Department of Health and identifies minimum engineering requirements for design, construction and operation of a public water system. 1.6.2.5 Department of Ecology The State Department of Ecology administers a variety of regulatory requirements that have a direct impact on operation of utility systems including the following: • Water rights and source of supply regulations; • Surface water quality regulations as put forth in WAC 173-201A; • Contract document review as authorized by WAC 173-240; and, Introduction Page 1.8 City of Port Orchard 2009 Water System Plan • Shoreline management permit administration in accordance with WAC 173-27; • Minimum engineering requirements for design, construction, and operation of public sanitary sewer systems. 1.6.2.6 Public Water System Coordination Act The Public Water System Coordination Act of 1977 (RCW 70.116) establishes procedures for adjacent water utilities and local government agencies to coordinate the planning and development of water facilities. These procedures are guidelines for providing future water service in the most efficient manner with the objective of coordinating water system development by geographical areas and integrating water system development with future land use plans. The City's water service area boundary has been approved by the Department of Health, Kitsap County, and neighboring jurisdictions through the Kitsap County Coordinated Water System Plan via the Water Utility Coordinating Committee. 1.6.2.7 Municipal Water Law Washington State's Municipal Water Law is a comprehensive regulation relating to certainty and flexibility of municipal water rights and efficiency of water use. The act more closely ties water system planning and engineering approvals by the Department of Health with water rights administration by the Department of Ecology. The legislation directs the Department of Health to adopt enforceable water conservation regulations for public water systems by the end of 2005. It was initiated as House Bill 1338 and became effective September 10, 2003. The Water Use Efficiency Rule associated with HB 1338 became effective in January of 2007. Compliance with the new rule requires that Public Water Systems with 1,000 or more connections develop a Water Use Efficiency (or conservation) Goal for a six year planning period. Goals had to be in place by January 22, 2008 and required a specific public involvement process. A plan for implementation and annual monitoring and reporting on progress toward the goal is also required. Other key elements of the Municipal Water Law include requirements for water rights assessment and evaluation and a requirement for demonstrated consistency between land use and water system planning. 1.6.3 County and City Regulations Because the City operates within unincorporated Kitsap County, it is subject to the rules and regulations established by the County. This is of particular importance when considering fire flow requirements and construction of water system improvements within County right-of-ways. In addition, the west side of Port Orchard water system abuts the City of Bremerton necessitating coordination with Bremerton in the event that water lines within Bremerton right -of ways are required.

Introduction � Page 1-10 \ftC SECTION 2 BASIC PLANNING DATA 2.1 GENERAL This Section provides an overview of the City of Port Orchard's water service area in relation to the city limits, the established service areas put forth by the Kitsap County Coordinated Water System Plan (CWSP) and the Urban Growth Area established for the City. A description of the service area and its geographical and demographic characteristics are presented. This Section also includes a summary of land use in the area as well as documentation of population and employment trends and projections. This information is needed for water demand projections, system analyses and recommendations presented in later sections of the Plan. 2.2 STUDY AND SERVICE AREA Figures 2-1 indicates the city limits, UGA and retail water service area for the City of Port Orchard and neighboring purveyors. The study area for this Plan is the City's retail water service area as put forth and agreed to in the Kitsap County CWSP. The 15.5 square mile service area includes the western portion of the city limits, as well as considerable land area that has not yet been annexed. While the City maintains water service to the majority of its estimated resident population of 9000 people, the West Sound Utility District (formerly known as Annapolis Water District) serves the eastern portion of the city limits and abuts the City of Port Orchard water system. The western portion of the service area contains the McCormick Woods residential community, and was annexed into the City of Port Orchard in August of 2009 during the final stages of development of this water system plan. McCormick Woods is provided water service by a technically separate water utility (with a distinct and separate DOH System Identification Number). While the system is physically independent of the Port Orchard water system serving the majority of the city, it is owned, operated and maintained under the City of Port Orchard's single water utility. All proposed development within the McCormick Woods area is addressed in this plan, including connection of the two systems and merging them into one water system. 2.3 SERVICE AREA POLICIES A variety of general goals and policies are put forth in the City of Port Orchard's 1995 Comprehensive Plan addressing Growth Management Act (GMA) Requirements and land use planning. The following service area policies provide more detailed information regarding how the system is operated and expanded. 2.3.1 Responsibility and Authority Ultimate responsibility for the City of Port Orchard's water utility is with the seven -person City Council and the City's Water and Sewer Committee is comprised of three Council Basic Planning Data Page 2-1 City of Port Orchard 2009 Water System Plan members that monitor the activities of water utility. The City's Public Works Director oversees general operation of the utility and a field operations crew is responsible for system operation and maintenance. 2.3.2 Annexation The primary policy of the City Council is that water service will be provided to properties within the city limits. If capacity is available, water service will be provided to residents of the Urban Growth Area (UGA) outside the City limits. Properties within the UGA requesting water service area are expected to annex to the City before service is provided. The City Council may consider exemptions to this policy if it is determined to be in the best interest of the community. In such instances, the City will accept a Developer's Extension Agreement which includes provisions that prohibit the property owner from protesting future annexation proposals. Until such time that the property is annexed, customers will pay a 50% surcharge on their water bills. In the event that the City annexes a property that is adequately served by another water utility that is authorized under the laws of the State of Washington, the City will not require a change in water service based solely on the annexation. Consideration of long term adjustments to the City's service area, however, may be required as development occurs within the City's Urban Growth Area and existing water service area. 2.3.3 Service Area Expansion of the Port Orchard service area beyond that established in the Kitsap County CWSP is not contemplated in this planning document. Any service area exchange or change would require specific negotiation with the neighboring jurisdiction and consideration by the Water Utility Coordinating Committee. With the Sinclair Inlet of Puget Sound to the north, the West Sound Utility District to the east and the City of Bremerton on the west, little opportunity for expansion of the service area exists. Only minor adjustments to the service area are possible and would occur only in a rare instance. Such adjustments in the service area, if required, would be handled on a case -by -case basis by interlocal agreement with neighboring utilities. It is the intent of the City of Port Orchard to maintain service to all areas within its existing service area and the City recognizes the right to assume responsibility for water service to all areas within the city limits. The West Sound Utility District serves the eastern portion of the City as stipulated in the Kitsap County CWSP. Other utilities adjacent to or surrounded by the City of Port Orchard's established service area are recognized in the Kitsap County CWSP. No plans for assumption of service responsibility of other utilities exist at this time. However, the City recognizes that extension of service to the areas served by small independent systems may be prudent under certain Basic Planning Data Page 2-2 City of Port Orchard 2009 Water System Plan circumstances. Examples might be if the small water system were to experience a source failure; in the event that the Port Orchard water system were to become a more cost effective and viable alternative for water service, or; if takeover of the system were requested. 2.3.4 Satellite Management The City of Port Orchard may consider satellite management of other water systems whereby the City would own, operate or assist with developments within its established service area. Such arrangements would be considered on a case by case basis and would require approval of the City Council. At this time, no such agreements exist and the City is not registered as a satellite management agency with the State Department of Health. 2.3.5 Other Local Government Policies Affecting Provision of Water The City will require all new developments such as subdivisions, to connect to the City water system. All new connections must comply with all applicable City standards. New developments outside the City limits at the time of development but served by the City's water system must meet City standards. New developments which are outside the City limits, are not currently served with City water but are located within the City's service area as established by the Kitsap County CWSP are required to meet City and CWSP standards. 2.3.6 Water Meters and Interties All water services are metered and read periodically to facilitate customer billings. The City maintains a wholesale connection from the City of Bremerton that is used from time to time as required to supplement water production from wells, but does not wholesale water to other utilities. A second intertie with Bremerton provides up to 350 gpm to the McCormick Woods portion of the system as discussed in Section 4 of this Plan. Emergency intertie connections with other utilities are permitted and considered on a case -by -case basis and depending on available water supply. Interlocal agreements dictating the financing and use of emergency interties are required. 2.3.7 Rates and Charges Water rates and charges are established by the City council and periodically reviewed and updated to ensure system viability and equitable rates. In addition to monthly rates and charges, all customers of the water system are required to pay an equitable share of the cost of water systems serving their individual properties and the cost of overall facilities required for the system as a whole. New connections to the system are required to pay for the extension of water service required to service their Basic Planning Data iii Page 2-3 City of Port Orchard 2009 Water System Plan property and a connection charge for their fair share of larger scale system components such as water supply, storage and transmission facilities. Water system extensions and improvements may be financed using Local Improvement Districts (LID's) whereby properties in a given area contribute to area -wide improvements and/or Latecomer Agreements where developer's receive a payback for facilities constructed as part of a developers extension provide a benefit to properties that are developed at a later date. Consideration of this type of financing would be by the City Council on a case by case basis. All new water accounts will pay fees in lieu of assessment or latecomer costs unless the property has participated in a Local Improvement District or other similar water system improvement. The City Council can waive the fee in lieu of assessment if the new development constructed a water system improvement which substantially improved the water system, as long as these improvements have been identified in the City's Comprehensive Water System Plan. Normally, developers finance water system improvements required to serve their property and deed the improvement to the City. The City Council retains the right to participate in joint improvements or to extend the water system as needed. If a developer extends the water system the City will allow a utility extension, or latecomers, agreement to be implemented. This agreement identifies specific properties that could benefit from the developer financed improvement and assess a fair share of the cost based on the termini or front foot method of assessment. A public hearing is required prior to implementing such an agreement. City Ordinance 1385 describes the agreement process. 2.3.8 Condition of Service Policy Water and sewer system improvements are considered separately for new developments. Connection to sanitary sewer is not a prerequisite to water service connection.

The two agencies maintain interties to assist each other in the event of an emergency situation. An interlocal agreement is in place and is included in the Appendices for reference. Additional discussion on interties and the operation relationship between the two utilities is documented in Section 4. 2.4.2 City of Bremerton The City of Bremerton serves west of the Port Orchard city limits and maintains a wholesale intertie connection with the Port Orchard water system along the waterfront at the western edge of the city limits. An intertie agreement is in place between the two cities and is included in the Appendices. The City of Bremerton has recently constructed a pump station and 16-inch water main to serve new development north of Old Clifton Road and west of Anderson Hill Road. This extension is consistent with the existing Port Orchard 580 Zone/Bremerton 580 Zone Plan for Cooperative Water System Development agreement between the two cities. The new pipe is intertied with the City of Port Orchard's 580 Zone system and meters are in place between the two systems. Future plans for water storage to serve the Bremerton area and the City of Port Orchard's 580 Zone on the north side of Old Clifton Road are outlined in the Cooperative Water System Development agreement. At this time the area is being developed such that water supply to the area could physically be provided by either entity and/or through interties. 2.4.3 Other Water Systems Several water systems operate adjacent to the City of Port Orchard's existing water system facilities and within the City's established service area. Other adjacent systems include the Sunnyslope Water System to the north and west of McCormick UGA and the Clifton Water system to the west of Anderson Hill Road. No interties exist or are contemplated with these purveyors Several small systems occur within the vicinity of ultimate service area boundary for Port Orchard and are recognized by the Kitsap County CWSP. These include the Clifton Water System, the Clifton Water Works and the Weyer Lane Water System. Although no specific plans for takeover of these systems is contemplated in this Plan, the City does acknowledge that assistance to these purveyors could be provided as the Port Orchard water system expands into the areas served by the independent water systems noted. At such time that it may become necessary due to source failure or the desire of the smaller Basic Planning Data JJJ Page 2-7 City of Port Orchard 2009 Water System Plan systems to receive direct service from a larger purveyor, direct connection to the Port Orchard system may provide a practical solution. 2.5 TOPOGRAPHY The City of Port Orchard is situated along the Sinclair Inlet of the Puget Sound. The city and service area generally slope toward the north and east. Elevations in the service area range from 320 feet in the southern portion of the area currently served by the Port Orchard system to sea level along the shores of the Puget Sound. The general character of the topography in the area is that of small hills, ravines and other minor land forms. Area topography is shown on the existing system map included at the back of this document. The topography of the area necessitates four pressure zones: the High, Intermediate and Low zones that serve the main portion of the system and two pressure zones in McCormick UGA area of the system. 2.6 LAND USE AND ZONING Land use and zoning within the service area is under the jurisdiction of the City of Port Orchard and Kitsap County. Figure 2-2 shows the Urban Growth areas for the City of Port Orchard in relation to the service area while Figure 2-3 presents Zoning/Land Use. As indicated, the City of Port Orchard has a significant Urban Growth Area and expects significant development in the future. As shown on Figure 3-3, the majority of the service area is designated for residential use with the highest concentration and density of residential development occurring in the downtown area and newer residential construction occurring in the area south of Tremont Street. More rural and less dense residential development occurs in the southern portion of the service area. The western portion of the service area has experienced significant development since publication of the previous water system plan with the development of the McCormick Woods community. Additional development within the McCormick UGA is proposed in this area and includes the McCormick North and McCormick West projects proposed for development prior to 2010. Also, the Glenwood Road JPA area east of McCormick Woods is zoned "Urban Low Residential' which allows development at a density of 4-9 dwelling units per acre. Development of the area is proposed during the six -year life of this Plan and would require extension of water service. This extension of service would be accomplished by the developing property owners and provides an opportunity for interconnection of the water system serving the 580 Zone with the main city water system.

Population and employment data, by Block Group, for the year 2003 was obtained from the Puget Sound Regional Council (PSRC). The corresponding population and employment within the service area was estimated by calculating the percentage of each Block Group within the service area and multiplying the percentages by the total population and employment for the Block Groups. Population projections were developed using Puget Sound Regional Council population and employment growth rates. The growth rates were applied to the existing population and employment estimates to establish projected population and employment figures. Office of Financial Management (OFM) information, local zoning and land use were reviewed to verify consistency with other City and County Plans. As indicated in Table 2-1, the current (2008) water service area includes a population of approximately 10,800 people and, based on regional growth projections and information on currently proposed developments, could increase to approximately 18,700 people by 2030. This represents a total increase in population of over approximately 42% and annual growth rate of approximately 1.92%. Employment within the service area is estimated at approximately 4,500 currently and estimated to reach nearly 5,700 by 2030. This represents an overall employment increase of approximately 22% and an annual growth rate of approximately 1 %. Please note that the City does not currently serve the entire service area and residents of the rural outlying area receive water from individual or small community ("six-pack") wells. Section 3 presents a summary of the number of connections served and both historical and projected water system demands. Section 3 also details the number of water system customers and water system demands separately for the main City and McCormick Woods systems. As noted in Table 3-1, in 2008 approximately 5,800 Equivalent Residential Units were served by the City. Nearly 5,000 ERUs are within the City System and just over 800 are served by the McCormick Woods System. This indicates an estimated population of 9,500 actually receiving water service in 2008. Recent development proposals and the economic decline of 2008 have been considered in finalization of this Water System Plan. While ultimate development projections have not changed significantly, the timing and expected type of development has. For example, the McCormick Woods West project was initially projected at occurring earlier in the planning horizon and with fewer units at a higher household size. Since the original Water System Plan was developed, the number of units has increased but significantly smaller lots and household sizes are anticipated. This is accounted for in the population projections presented in Table 2-1 and later in this Plan where water demands and system requirements are identified (Sections 3 and 6 respectively). As noted in Table 2-1, 1545 units are proposed for the McCormick Woods West development. That development is adjacent to the existing McCormick Woods system and initially will receive water supply only from the McCormick system. An additional 1000 units are proposed for the Glenwood Basic Planning Data E Page 2.13 City of Port Orchard 2009 Water Svstem Plan JPA that is geographically located between the Port Orchard and McCormick systems. Water system facilities serving the JPA will provide the link between the Port Orchard and McCormick systems allowing for one integrated water system in the future.

Development of the Glenwood JPS is assumed to be phased addition of 1000 dwelling units with 2.5 persons perhousehold. Basic Planning Data ^ Page 2.14 SECTION 3 WATER DEMANDS AND CONSERVATION 3.1 GENERAL Identification of historical and projected water system demands is critical in evaluation of the water system's ability to meet the needs of current and future populations of the water service area and provides the basis for water system modeling and analysis. The following paragraphs outline the methodology used for assessing historical water use and developing future water demand projections. Please note that although this planning process has had the benefit of the most current (2000 Census population and employment) data available at a high level of detail (block groups), water demands are extremely vulnerable to influences such as weather patterns and conservation programs. In addition, the types of water users (commercial versus residential) will have a significant impact on seasonal variations in demands and peaking factors. Water system demands have been presented for two scenarios; one assuming water use patterns will continue consistent with historical trends, and one that assumes conservation will reduce per capita water use. Following discussion of overall water system demands is historical and projected demands for the two separate water systems served by the Port Orchard water utility: the City of Port Orchard system that serves the central city area, and; the McCormick Woods system that serves the recently western portion of the City annexed in August 2009. 3.2 HISTORICAL WATER DEMANDS In order to calculate future water system demands and associated source of supply and water system requirements, two steps are required: comparison of water purchases to actual water sales and determination of historical water use characteristics of the various types of connections served. A summary of overall water supply is provided in Table 3-1 while Sections 4 and 6 provide more detailed information of individual sources of supply for each of the two system comprising the Port Orchard water utility by facility. As indicated in Table 3-1, non -revenue water refers to water loss through leaks, breaks and unmetered water use. The City's non -revenue water is estimated at 9.24% in 2004 before consideration of construction uses through hydrant meters. Non -revenue water has been of significant concern to the City in the past, especially as it related to water use at McCormick Woods Golf Course. City meters indicate that more than 35 million gallons of water were directed to the golf course with only a portion of that water was recorded for billing purposes. A top priority in control of future water use and conservation is clarification of water use for irrigation and consideration of new policies governing the metering of and payment for irrigation water. Part of the solution to irrigation at the McCormick Woods Golf Course will be use of the recently completed McCormick Woods Well 4B, a dedicated irrigation well, and isolation of that facility from the potable water system. PACE Water Demands & Conservation Page 3.1 City of Port Orchard 2009 Water System Plan A summary of water use by customer class is presented in Table 3-2 and Figure 3-1. This information provides generalized data for detailed water demand forecasting, especially when larger scale residential or commercial activities are proposed. For the purpose of this Plan, detailed historical demand data is summarized to provide total per capita water use documentation for future demand projections. Table 3-3 presents more detailed data on a monthly basis and as discussed below, provides the basis for more detailed analyses and design criteria. As indicated, residential water sales constitute the bulk of water sales in the City with single- family connections accounting for approximately 66% of the total annual water demand. In 2008, commercial customers used almost 20% of total water demand; irrigation (through dedicated irrigation meters) accounted for 4%, governments other than the City of Port Orchard used 9% and the City of Port Orchard used approximately 0.5% of the annual total. Review of seasonal water use summary presented in Figure 3-2 presents a clear picture of how water use varies from winter to summer months. Please note that the data presented is for billing months and typical represents a one month lag from actual water use. Of particular note on Figure 3-2 is the significant residential water use increase in the summer months. This increase is in addition to the metered irrigation water use that is also indicated. Since commercial use remains relatively consistent through the year, this information suggests that lawn watering would be a key target area for conservation activities. Commercial and other government use categories show a less dramatic increase in the dryer summer months. In the commercial category, especially in a waterfront community such as Port Orchard, it is often difficult to distinguish between increased outdoor water use in the summer and increased use due to increased recreational and commercial activities. A combination of monitoring outdoor water use and consideration of water efficient fixtures might assist in reducing summer peaks and overall water use. The same is typically true for 'other governmental" uses such as schools. Additional discussion of conservation activities is provided later in this Section. Table 3-3 presents detailed information on the City's historical water demand for the past five years. Review of this data, together with daily water production data from each source, indicates the overall peak day for the City is estimated at 2.5. It is noted, however, that while the peaking factor for the Port Orchard portion of the system is approximately 2.25, water production rates in for wells serving the isolated McCormick Woods portion of the system indicate a that the peaking factor has reached 4.0 on occasion. The reason for this has been identified as operational issues leading to reservoir overflows that have since been corrected. Correction of this issue, coupled with removing golf course irrigation from the domestic water system and the use of low water use fixtures in any new construction in this area will significantly mitigate peak summer demands on the system in the future. A peaking factor of 2.25 has therefore been assigned to the entire water system. The peak hour demand all portions of the system has been estimated at approximately 4.2 times the average day demand.

The City has initiated a diligent tracking system in association with its Water Use Efficiency program and future water use tracking will include more detail. 2 "Authorized Other Uses" of water include fire fighting, construction water use, flushing, city water system operations and maintenance, and other uses where water consumption can be accounted for and either metered or estimated with reasonable accuracy. s "Leakage" refers to unaccounted for water that is lost through breaks, leaks, and theft (including unauthorized hydrant usage and/or system connections). Inconsistent tracking prior to 2004 prohibits calculation of leakage rates for those years.

Separate projections for water use with and without conservation are presented in Table 3-4 and 3-5. The projections assume that development within the established service area will be served by the water system and that property within the area will develop according to the general zoning designations currently in place. The projections reflect significant growth in certain parts of the service area, especially in the western area surrounding McCormick Woods and development within the Glenwood Road JPA and are based on the growth projections developed in Section 2. Note that 1000 ultimate ERUs associated with the area in and around the Glenwood JPA have been included with the McCormick Woods or 580 Zone projected demands. This is because the area will likely be served by gravity from the facilities proposed for the McCormick Woods development. As described under the system analysis section of the Plan, however, the Glenwood JPA area will serve as an interconnect between the main City system and the McCormick Woods system. This will allow for source and storage to the JPA to be a combination of the two currently separate systems and reduce the overall capital improvement requirements for the development.

The City has adopted the following goal after the requisite public process and is developing a plan for monitoring progress toward the established goal and reevaluation of water use efficiency measures on an annual basis. Additional documentation regarding the Water Use Efficiency Program sis provided in the Appendices. GOAL #1: Over the next six year period the City of Port Orchard will reduce Single -Family Residential water consumption by 5 gallons per day per home. This reduction in single-family residential use will save approximately 2.5 million gallons per year over this six year period. The following measures will be evaluated and/or implemented to assist in attaining this goal: • Include water conservation information in the City's annual Consumer Confidence Report (annual water system report to consumers). • Evaluate the inclusion of inserts as part of the monthly water bills that presents information regarding the importance of water conservation and actions individuals can implement to reduce their water use. • Investigate a Water Conservation School Outreach Program that may include school presentations, preparation of curriculum material, water conservation education handout material, and tours of water system facilities. • Prepare a portable display of water conservation devices and selected material for display at the City's numerous events and festivals. • Recommend consumers to contact PUD #1 to obtain dye tablets for in home leak detection. 3.5 WATER CONSERVATION PROGRAM Water conservation is an important and viable means of reducing water system demands and in the City of Port Orchard's 1995 Water System Plan, a target goal of a 10% reduction in per capita demand prior to the year 2000 was established. The premise of the program established in the previous Water System Plan remains unchanged, with the City relying heavily on the conservation messages of larger agencies as a means of education and awareness and implementing internal measures conducive to stewardship of clean water as a finite resource. Key elements of the conservation program are outlined in the following paragraphs. 3.5.1 Internal Conservation Measures Water meters are a key element of an effective conservation program. Source meters are provided and maintained on all permanent sources and recommended for emergency Water Demands B Conservation P� AC )E Page 3-9 City of Port Orchard 2009 Water System interties. Individual customer meters are required on every connection to the Port Orchard Water system. • Source Meters — The City currently has master source meters in place at all of its well supplies and at the metered intertie with Bremerton. Meters are recommended for emergency interties. • Water Meters - All connections to the water system are metered. Irrigation meters are available for interested customers and required on new irrigation accounts. • Hydrant Meters - Hydrant meters are currently required for all water drawn from hydrants except that associated with emergency use (such as a fire). Hydrant permits are required in addition to the permit fee, permit holders are charged for water use. • Consumption History - Consumption history is provided as requested by customers and is not shown on bi-monthly billings to promote conservation. • Non -Revenue Water - The City's on -going maintenance and repair schedule provides for routine inspection of facilities and results in the prompt repair of leaks and valve failures that contribute to non -revenue water. In addition, field crews perform routine maintenance and operation in a conscientious manner to reduce the amount of water used for these activities. Hydrant meters are for all non -emergency water use. • Leak Detection — The City retains the services of leak detection specialists annually to identify leaks in the system. The last leak detection analysis was performed in 2005 and no major leaks were identified. All identified leaks were subsequently repaired. • Pressure Regulation - The City maintains five separate pressure zones in order to ensure that adequate fire flows and pressures are maintained to all areas of the system. By effective management of the pressure zones, water consumption can be reduced by controlling pressures at a safe level in accordance with State Department of Health guidelines. Isolated areas of high pressure are controlled by the use of individual pressure reducing valves 3.5.2 Conservation Program Promotion Utilizing public information and promotional materials to encourage conservation is key to any conservation strategy. The City of Port Orchard's annual newsletter is recommended as way to distribute conservation tips and raise awareness. Water bills also provide an area for conservation program promotion. Further program promotion through distribution of conservation materials produced by others (i.e. AWWA, DOH, and Kitsap County PUD) is proposed. 3.5.3 Rate Setting to Encourage Conservation The City has implemented a water rate schedule to encourage conservation that employs a block rate structure whereby water use in excess of established thresholds is priced higher. The new rate structure will provide a threshold for evaluating conservation by various customer types and help determine what type of education and conservation Water Demands a Conservation Page 3.10 6;Ai / City of Port Orchard 2009 Water System Plan programs will be most useful in the future. Annual review of the impact of any adjustments to the water rate schedule on conservation and water use will be accomplished as part of overall Water Use Efficiency tracking and reporting in accordance with State regulations. Review of irrigation policies and charges is also highly recommended. A summary of current water rates is provided in Section 10 of this Plan. 3.5.4 Encouraging Water Saving Devices The City of Port Orchard has adopted the most current version of the Uniform Building and Plumbing Codes to regulate and enforce the provision of low water use fixtures in all new construction. Future consideration of low water use landscaping provisions in the City Code is recommended. 3.5.6 Water Efficient Toilets and Appliances The City relies on the public messages of regional water purveyors and the appliance industry to promote water efficient appliances, especially washing machines. The City of Port Orchard recognizes that toilets are responsible for more than 30% of indoor residential water use. It is estimated that the vast majority of toilets within the city are high flow toilets (toilets installed before 1980 are typically 5 to 7 gallons/flush, toilets installed between 1980 and 1992 are 3.5 gallons/flush and toilets installed after 1992 are 3.5 to 1.6 gallons/flush.) If each of the high flow toilets were converted to low flow (1.6 gallons/flush), it is anticipated that approximately 16,000 gallons of water per household would be saved each year in our community. Savings of nearly 8 million gallons per year could be realized with conversion to low flow toilets throughout the City. Residents who take advantage of the program receive a cash rebate of $100 on the installation of a low flow toilet. The low flow toilet program provides another indicator for use in annual Water Use Efficiency program evaluation, reporting and tracking. 3.5.7 Water Reuse and Recycling The City of Port Orchard and Karcher Sewer District jointly own a wastewater treatment plant that was recently upgraded to increase capacity and generally improve the plant operations. The two agencies are working together to pursue opportunities for reuse of treated effluent form the plant. Several businesses have expressed interest in participating in this program. All potential water reuse opportunities will be considered with respect to DOE and DOH requirements. Specific review and analysis of irrigation opportunities is recommended. Water Demands h Conservation �`\J Page 3-71 City of Port Orchard 2009 Water System Plan 3.6 CONSERVATION PROGRAM IMPLEMENTATION AND MONITORING Water Use Efficiency and Conservation program monitoring to quantify and document the effectiveness of the conservation program is accomplished through an ongoing data collection effort that relates to conservation. In accordance with State requirements, Port Orchard will achieve this by annual review of water use records and comparison to previous years. Water use data is kept by customer classification in order to identify annual and specific trends for summer and winter water use. This data, coupled with information regarding weather and implementation of any new conservation programs, provides a mechanism for monitoring overall water conservation efforts. The first annual water use efficiency report sets the baseline for future evaluation and is provided in the Appendices. Continued participation with neighboring purveyors and the South Kitsap WUCC is required to ensure that consistent conservation messages are being delivered throughout the South Kitsap County area and region and develop new ideas for water conservation mechanisms and programs. City employees are encouraged to participate in water conservation data collection, seminars, and workshops that are relevant to their particular field. Water Demands Q Conservation Page 3.12 A E SECTION 4 EXISTING WATER SYSTEM 4.11 OVERVIEW The City of Port Orchard's water system is best described as two separate water systems, the original city system that serves the majority of the City through a series of wells, storage reservoirs and distribution facilities; and the isolated McCormick Woods system which serves the more recently developed McCormick Woods community with a separate water supply wells, storage tanks and distribution system facilities. Although the two systems are planned to be connected, as discussed in Section 6, they are referred to and described in this section as the Port Orchard and McCormick Woods systems. Analysis of each system and the proposed strategy for interconnection are put forth in Section 6. Both systems are fully metered and together they serve a total of approximately 3550 connections, most of which are single family residential. The existing systems are indicated on the water system plan map at the back of this document and generally illustrated on the hydraulic profile shown on Figure 4-1. 4.2 PORT ORCHARD [CITY] SYSTEM The area known as Port Orchard's City System is exclusive of the 580 Zone System and serves approximately 5000 ERUs. The area is consistent with a small city with primarily single family residential connections and a downtown area with small commercial establishments. In addition, the City System provides service to multi -family residences, schools, commercial complexes, and the government offices of both the City of Port Orchard and Kitsap County.. The system includes the older portions the City along the waterfront as well as the more rapidly developing uplands. The Port Orchard water service area is generally bounded by the waterfront on the north, Sedgwick Road in the vicinity of State Highway 16 on the south, Anderson Hill Road on the west, and the West Sound Utility District on the east. The system consists of three pressure zones to regulate pressure within the community, although individual PRVs reduce pressures in areas of undulating topography where high pressures would be expected. These Zones have historically been referred to as the High, Low and Intermediate Zones. This Plan includes the Hydraulic grade line of each zone for ease and clarity in describing the system(s). The Low or 260 Zone is extends from sea level to an approximate maximum service elevation of 210 feet and serves approximately 33% of the existing population and employment base served by the City System. The 260 Zone is fed primarily by Wells 6 and 7 but can receive backup supply from a wholesale meter connection to the City of Bremerton system west of the City. Well water is pumped through the City Hall Pump Station which includes a stilling basin that is utilized for settling and hydrogen sulfide dissipation. Fire flow in the higher elevations of the 260 Zone is supplemented by parallel pipes and "high flow' hydrants from the 390 Zone. The 260 Zone has approximately 2.15 million gallons of storage in three facilities: the Morton Street Standpipe, Park Reservoir and Maple Street Elevated Tank. Existing Water System /// Page 47 City of Port Orchard 2009 Water System Plan The High or 390 Zone of the City System serves approximately 66% of current connections to the City System in the residential uplands of the City and commercial area in the east. The 390 Zone serves elevations from approximately 210 feet to just over 300 feet. Well No. 9 located at the Van Zee Park site is the primary source to the 390 Zone, although additional supply can also be received from the City wells or Bremerton supply in the 260 Zone through the Melcher Street pump station. Approximately 2.1 million gallons of storage in this zone are provided in the Old Clifton, Sedgwick and South Sidney reservoirs. To improve pressures in the higher elevations of the City located east of Blackjack Creek the High Zone was expanded in 1983 with a 12-inch main that crosses the Creek. Interties with West Sound Water System in this area, as well as the ability to revert back to serving the area from the low zone provide the necessary reliability for the isolated portion of the 390 Zone. An intertie to the West Sound Water System provides a backup source to the southernmost reaches of the City limits. The 6-inch intertie is located on the 1 million gallon Sedgwick Reservoir site. The Intermediate or 336 Zone was created in 1984 to provide satisfactory water pressure to a small area north of Kendall Street in the vicinity of Harrison Avenue. The 336 Zone is supplied by a PRV from the 390 located just south of Kendall and Harrison and storage is provided from the 390 High Zone. The 336 is fed by the 390 Zone and because of hydraulic continuity and the small size of the Zone, it has been considered and analyzed together with the 390 Zone. 4.3 580 ZONE (MCCORMICK) SYSTEM The 580 Zone (McCormick) System began as a private water company serving a residential, golf course and clubhouse and commercial development in an unincorporated portion of the Port Orchard water service area and was taken over by the City of Port Orchard in 1998. A December 26. 2001 interlocal agreement details various aspects of water system construction, assumption of the system by Port Orchard and the terms of an intertie with the City of Bremerton that can supply water to the McCormick Woods area. A copy of that agreement is included in the Appendices. Water system planning for this portion of the water system has been accomplished through updates to the original water system plan and was completed in 2000 and 2003 under the title McCormick Woods Water Company Water Comprehensive Plan Amendment(s). The McCormick Woods System consists of an independent source of supply, a network of 6- to 16-inch distribution and transmission mains and pumping and storage facilities. Three groundwater wells (McCormick Woods Wells 1, 2, and 3) have historically provided water supply to the area. In 2009, during finalization of this Water System Plan, an additional domestic supply well was constructed to replace the three previous wells. Golf Course irrigation is accomplished by a private well (46), a recently developed well dedicated to this purpose. Storage consists of a 450,000 gallon steel reservoir connected to the system by a 16-inch transmission main and two low level concrete tanks located adjacent to the wells. Water from the three supply wells is pumped directly to these two lower reservoirs provide equalizing storage for the system. A pump Existing Water System ��������w�'''''''���� Page 4.2 ((((PACE) City of Port Orchard 2008 Water System Plan station transfers water from the two intermediate tanks to the 450,000 gallon reservoir. The overflow elevation of the 450,000 gallon reservoir is 580 feet and the entire McCormick Woods system is served by gravity from the 580 reservoir. As such, the McCormick Woods system is referred to as the 580 Zone. An existing agreement with City of Bremerton provides for up to an additional 350 gpm (285 acre feet per year) subject to the conditions contained in the aforementioned December 26, 2001 agreement. 6 Existing Water System /// Page 43 City of Port Orchard 2009 Water System Plan r.:f�r FrlrjFYjTffPlTfjJl�7 Ui lI'l Existing Water System /�a.e���� Page 4.4 \�C §0§/ !�§ 0 | °�Ld ° §(§ [(§\ o } 4 F-°� §(§| \� § / 7 ( - ( `10 | |\ �\t §|§\ §§■§ / 2� §� !f k� ° § !§� • |� wag `� Q . | H § °((_ � |22 E } 22 b d� § z # - b2 j \ \\ / K § 0m � 3 \` (L(} \ | § : ' ` 0 )|/(( ° ( § § »w$m! § § ) $ / / City of Port Orchard 2009 Water Svstem Plan Existing Water System PACE Page 4-6 City of Port Orchard 2008 Water System Plan 4.4 WATER SUPPLY 4.4.1 City System Supply to the Port Orchard System is primarily through City -owned and operated groundwater wells, some of which are flowing artesian wells. A summary of existing and pending water rights is presented in Table 4-1 and summarized water rights information is contained in the Appendices. The requisite water rights self assessment is also contained in the Appendices in accordance with Municipal Water Law requirements. As noted the City maintains four existing water rights the various wells that serve serving the Port Orchard portion of the system normal conditions (PO Wells 5, 6, 7, and 8/9). The only treatment provided in the Port Orchard system is removal of hydrogen sulfide and the addition of chlorine and fluoride. To improve supply and meet the projected demand within the service area, the Well 10 was drilled in 2006 under an initial water right application for 500 gpm. The new well is expected to yield in excess of 1,500 gpm. An additional 1,000 gpm water right application is currently under consideration by the Department of Ecology and if granted, will result in a Well 10 total water right of 1500 gpm. Transfer of water rights from Wells 4, 5, and 6 may also be considered in the future. City Well 4 has an artesian flow of about 40 gpm located under the City Hall parking lot. Occasionally when water from Well 4 is not used, it overflows into the Bay. The Department of Ecology has requested the City modify the well operations to eliminate water waste. Because of the small quantity of water from Well 4 and its location, it is recommended that the well be sealed and the water rights transferred to Well 10. Likewise, the City wishes to abandon Well 5 and transfer any water rights associated with it to Well 10. Currently Well 7 water also flows to the City Hall facility. The recommendation includes treating Well 7 water elsewhere and bypassing the City Hall site and allowing for additional parking or other City uses. 4.4.2 580 (McCormick) System The McCormick Woods or 580 Zone of the system is served by three existing domestic supply wells (MCW Wells 1, 2, and 3) from the shallow aquifer underlying the area. No treatment except chlorination is provided in the McCormick Woods system. As discussed earlier, the 580 Zone is intertied with the City of Bremerton's water system. By agreement, fluoridated water is prohibited from entering the Bremerton system until the systems are separated. The City has made application to combine water rights for McCormick Woods Wells 1, 2, and 3 into a new Well 11 proposed for drilling into the deep level aquifer. By doing this, the City would obtain an additional 150 gpm, bringing the total McCormick Woods water right to 750 gpm. Well 11 was drilled in 2009, and brought on line in 2009/2010.

Existing Water System Page 4.8 \OC/ City of Port Orchard 2008 Water System Plan 4.5 PUMPING Due to the topography of the area and for reliability and operational flexibility, the City of Port Orchard relies on three pump stations in addition to well pumps to move water throughout the system. The pump stations are detailed in Table 4-2. The City Hall Booster Station pumps water from the Wells 4 at Kitsap Street and Well 7 near Port Orchard Boulevard and High Avenue into the City's Low or 260 Zone. The Station consists of a stilling basin to allow sand sediment to settle and provide time for dissipation of hydrogen sulfide. Chlorine and fluoride injection is also accomplished at the City Hall Booster station. This station is over 60 years old and needs upgrading. The Melcher Street Pump Station was constructed in 1960 and supplements supply from the 260 Zone to the 390 Zone. The Station is equipped with two pumps and standby power. The Well 6 pump station pumps treated water from the Well 6 clear well into the 260 Zone. It is located on Maple Street west of Bethel Avenue. This station is over 60 years old and needs significant upgrading. The McCormick 580 pump station transfers water from two 60,000 low level concrete reservoirs on the McCormick Well site to the 450,000 gallon reservoir that serves the McCormick Woods development. The station is equipped with three separate pumps that were originally designed to maintain pressure in the system during varying demand conditions but have since been redirected through a 16-inch transmission main on Old Clifton Road to the reservoir. Emergency power is provided at the station.

The system was constructed over a number of years as the City developed but the majority was installed in the 1960s. Pipe Size and materials are categorized in Table 4-4. One pressure reducing valve supplies the 336 Intermediate Zone from the 390 Zone. The 390 and 260 Zones are connected by the Melcher Street Pump Station supplying water to the 390 Zone. Flow from the 390 Zone to the 260 Zone can only occur by manually opening valves located at seven separate intersections.

The minimum design criteria of the City must also be in accordance with the criteria established by the Kitsap County Coordinated Water System Plan (2004 Revision). Minimum design criteria addressed in this appendix include water supply requirements, storage volume, distribution system and transmission main capacity, and water quality standards. These criteria are used to determine deficiencies in the existing water system and establish design requirements for the future water system within the City's service area. 5.2 STATE AGENCY REGULATIONS The Washington State Department of Health's "Water System Design Manual" (August 2001) is the primary document governing the sizing and design of Group A public water systems in the state of Washington. This publication sets forth the minimum design guidelines and planning requirements for the supply, storage, distribution, and quality of potable water within Group A public water systems. 5.3 REFERENCE DATUM The datum used for planning of facilities in this study and for City design work is based on NAD 83 State Plane Washington North. 5.4 GENERAL CONSIDERATIONS 5.4.1 Design Period In planning water facilities, it is necessary for the design to be adequate over a specific period of time. The period of design for this study is approximately 20 years. This means that in the year 2025, the facilities proposed in this study may have reached their maximum supply capacity, assuming that the population projections are reached. Many of the components of the water system, however, have much longer useful lives than 20 years and will continue to serve the community far beyond the design period. 5.4.2 Planning Initial system construction and additions should conform to the comprehensive plan. AAA Minimum Design Criteria (PACE) Page 5.1 City of Port Orchard 2009 Water System Plan Public water systems should be designed to provide fire fighting capability in accordance with the requirements of the local Fire Marshal. Phased development is permitted where full development will take several years. 5.4.3 Reliability Multiple water sources are recommended in combination with adequate emergency reserve in gravity storage to allow for interruption of supply at one point, while still maintaining water supply to the system at the design rate. Looping of the water mains to improve circulation quality and fire flow is an on -going goal of the City. Pumping stations are to contain multiple booster pumps of sufficient capacity to meet the maximum day demands with the largest pump out of service. Auxiliary power is required where adequate gravity storage is not provided. 5.5 WATER SUPPLY RECOMMENDATIONS AND REQUIREMENTS The DOH "Water System Design Manual' sets forth the following recommendations for water supply systems and pump stations, with additional requirements for booster pump stations. 5.5.1 Water Supply and Source Pump Stations Source capacity must meet the maximum day demand of the system. It is also recommended that the source is sufficient to meet the maximum day criteria while concurrently replenishing the fire suppression storage volume within 72 hours of its depletion. Port Orchard recognizes that alternate and independent sources of supply, such as interties with other water systems, coupled with adequate storage capacity may provide a sufficient level of reliability on an interim basis. Water source pump stations should be capable of providing the maximum day demand for the system with 18 hours of pumping. Pump stations shall be provided with a minimum of 20 pounds per square inch (psi) at the inlet side of the pumps under peak hour demand or fire flow plus maximum day demand rate conditions. Pump stations shall have an automatic shut-off in place for when the inlet pressure drops below 10 psi. Minimum Design Criteria Page 5-2 ACE City of Port Orchard 2009 Water Svstem Plan Pump stations shall have power connections available to independent primary public power sources or provision for in -place auxiliary power if the pumps provide fire flow, or are pumping from ground level storage. 5.5.2 Booster Pump Stations Open system Booster Pump Stations, which transfer water to a higher pressure zone governed by an atmospheric storage tank, shall be capable of providing source capacity as established for water supply sources in Section 5.5.1. Closed system Booster Pump Stations, which transfer water to a higher pressure zone closed to the atmosphere, shall provide peak hourly demand with a minimum of 30 psi of pressure at all connections. It is recommended that this capability be provided with the largest pump off-line. Closed system BPS shall provide fire flow in conjunction with maximum daily demand with 20 psi of residual pressure. Additionally, since this system is located in an area governed by the Public Water System Coordination Act of 1977 (PWSCA), this capability must be provided with the largest pump off-line. 5.6 WATER DISTRIBUTION RECOMMENDATIONS AND REQUIREMENTS 5.6.1 Water Pressure Water systems shall be designed to provide peak hourly demand with a positive pressure of 30 psi at every connection to the system (Normally at the property line of the service connection. For fire flow, the distribution system shall be designed to provide the required fire flow and maximum daily demand at a residual pressure of 20 psi throughout the system. Required fire flow shall be established by the local Fire Marshal. Maximum pressures in the distribution system shall not exceed 100 psi When pressures exceed 80 psi, the customer should provide and maintain individual pressure reducing valves (PRV) in accordance with the provisions of the Uniform Plumbing Code (UPC). 5.6.2 Pipe Sizing and Materials Maximum velocity in distribution pipelines shall not exceed 8 feet per second (fps) under peak hour demand conditions. Flow velocities during fire events may exceed this maximum limit, but shall remain below 10 fps. Minimum Design Criteria Page 5.3 City of Port Orchard 2009 Water System Plan Minimum pipe diameter for all distribution mains and mains providing fire flow is 6-inches nominal inside diameter, except for looping and dead-end mains beyond hydrants as approved by the City. All pipelines shall be designed and constructed to ultimate domestic and fire flow conditions as determined by the City. Dead end mains are generally not accepted by the City, except in phased development projects or where no potential for future interconnection of facilities exists. Approved dead end mains, which will not serve fire hydrants, may be 6-inches in diameter in residential areas and 8-inches in commercial areas or as hydraulically justified and approved by the City. New water mains shall be constructed of cement mortar lined, ductile iron pipe conforming to AWWA C 151 and C 104, minimum thickness Class 52 conforming to ANSI/APWA C 105-72. All water main fittings are to be cement mortar lined, ductile iron conforming to AWWA C 110 or C 153, with 250 psi minimum working pressure. All push -on and mechanical joints are to conform to AWWA C 111, and restrained joints shall conform to City requirements. All water system pipelines shall be constructed of 'lead-free" materials (less than 8% lead content). Minimum cover over pipes 12-inches in diameter and smaller shall be 36 inches minimum, and 48 inches minimum cover over pipes greater than 12-inches in diameter. Maximum cover over pipe shall be 60 inches. Transmission and distribution pipelines shall be at least 10 horizontal feet from any existing or proposed sanitary sewer utilities and 5 horizontal feet from other utilities, measured edge -to -edge. At least 18 inches of vertical separation (measured edge -to - edge) shall be maintained between the top of a sanitary sewer main and the bottom of a water line. A minimum vertical separation of 6 inches, measured edge -to -edge, is required between all other utilities. Exceptions to these minimum standards must meet the special requirements set forth by the Washington State Department of Ecology and must be approved by the City. 5.6.3 Valves Valves shall be ductile iron and shall be installed in a configuration that permits isolation of lines. Minimum Design Criteria Page 5-4 ACP E City of Port Orchard 2009 Water System Plan Valves should be installed at intersections, and with normal maximum spacing at 500 feet in commercial, industrial, and multi -family areas, 600 feet in residential areas, and 1/4 mile in transmission mains. Additional isolation valving may be required by the City and will be determined on a case -by -case basis. Air entrainment, air release, or combined air -vacuum relief valves are to be installed at appropriate points of high elevation in the system. All piping in the system shall be sloped to permit escape of any entrained air. Zone isolation valves shall be installed at zone boundaries to permit future pressure zone realignment without the need for pipe realignment. A blow -off assembly or fire hydrant shall be installed on all dead end runs and at designated points of low elevation to provide a means for adequate flushing of the system. The blow -off assembly shall be installed in a utility right-of-way, except where a written access and construction easement is provided to the water utility. In no case shall the location be such that a possibility of back-siphonage into the distribution system exists. The blow -off assembly shall be sized to achieve a minimum flow velocity of 2.5 feet per second in the main. 5.6.4 Fire Hydrants Fire hydrants shall comply with the minimum requirements established by the local Fire Marshal having jurisdiction and meet the type, location and spacing requirements of the agency having jurisdiction in the project area. In general, minimum spacing for hydrants in commercial and multi -family areas shall be 300 feet on center and 600 feet on center in single-family residential areas. 5.6.5 Cross Connection Control Where the possibility of contamination of potable water exists, water services shall be equipped with appropriate cross connection control assemblies in accordance with DOH requirements and the City's Cross Connection Control Program. The need and location of cross connection assemblies shall be determined by the City. 5.7 STORAGE RECOMMENDATIONS AND REQUIREMENTS Storage requirements are based on five components; operational storage, equalizing storage, standby storage, fire suppression storage and dead storage. The minimum requirements for each of the components of the total storage requirement are summarized below. The minimum amount Minimum Design Criteria P� ACE Page 6.5 City of Port Orchard 2009 Water System Plan of storage required shall be adequate to provide for equalizing storage plus the larger of standby or fire suppression storage. The recommended storage volume is equal to the sum of the equalizing, standby and fire suppression storage components. Figure 5-1 illustrates the various storage components of total required storage. Part 6 of this document includes a complete analysis of the City's water storage requirements and existing capacities.

This volume varies according to the sensitivity of the water level sensors controlling the source pumps and the configuration of the tanks designed to provide the required volume while preventing excessive cycling of the pump motor(s). The volume of operational storage is therefore dependent upon pump design parameters, and is not impacted by the minimum design parameters set forth by DOH. 5.7.2 Equalizing Storage Equalizing storage is the volume of water required to supplement source pumping capacity when system demands exceed the source pumping capabilities. The volume of equalizing storage must be sufficient to meet hourly water system demands in excess of the rate of Minimum Design Criteria Page 5-6 \G City of Port Orchard 2009 Water System Plan supply and must be at an elevation sufficient to meet these demands at a minimum delivery pressure of 30 psi. The amount of required equalizing storage is to be calculated in accordance with the DOH "Water System Design Manual" 5.7.3 Standby Storage Standby storage is required in order to augment the available supply of water during a period of restricted flow from the supply source. Restriction of flow may be caused by a pumping equipment failure, supply line failure, maintenance or repair, or other conditions that may cause interruption in supply. For single source systems, standby storage requirements are twice the average day demand for a system, deliverable at 20 psi. For a multiple source system, the standby storage is calculated as twice the average day demand, less the flow available with the largest source out of service, multiplied by the amount of time the remaining sources will be pumped each day. It is recommended that standby storage not be less than 200 gallons per connection per day. 5.7.4 Fire Suppression Storage Fire suppression storage must be equal to the amount of water required to accommodate fire demand while maintaining a minimum system pressure of 20 psi. Fire flow requirements are determined by the Fire Marshal having jurisdiction and generally conform to the procedures utilized by the Washington Surveying and Rating Bureau as set forth in a pamphlet entitled "Guide for Determination of Required Fire Flow" published by the Insurance Services Office, Municipal Survey Service. 5.7.5 Dead Storage Dead storage is the amount of water not available to all customers at the minimum design pressure. Dead storage is not considered when determining volumes to provide operational, equalizing, standby or fire suppression storage. 5.8 GENERAL FACILITY PLACEMENT All piping, pumping, source, storage and other facilities, shall be located in public rights -of -way, dedicated utility easements or on City -owned property. Utility easements must be a minimum of 15 feet in width, and piping shall be installed no less than 5 feet from the easement's edge. Any exceptions to this minimum easement will be at the discretion of the City. Unrestricted access shall be provided to all public water system lines, appurtenances, and fire hydrants. The location of utilities shall be in accordance with the standards and guidelines established by local jurisdiction criteria. Where existing utilities or storm drains are in place, new facilities shall conform to these standards as nearly as practicable and yet be compatible with the existing installations. 6G Minimum Design Criteria /` Page 5-7 City of Port Orchard 2009 Water System Plan 5.9 WATER QUALITY STANDARDS Section 8 of this Plan puts forth detailed information regarding the maximum contaminant levels allowed in drinking water supplies as put forth by the Washington State Department of Health (DOH) at the time of publication of this Plan. Additional requirements of the federal Safe Drinking Water Act (SDWA) are also discussed, along with the City's plans for additional future monitoring. 5.110 STANDARD PLANS AND DETAILS In accordance with WAC 246-290-120, the City maintains standard plans and details on file with the State Department of Health. These standards address construction requirements for: the installation of hydrants, valves, fittings and meters; repair or replacement of system components with similar components; and maintenance or painting of surfaces not contacting potable water. The standard plans and specifications also constitute a waiver from formal submittal and approval of specific distribution main improvements provided that construction of such projects are certified by a registered professional engineer and provided that the City submits required documentation to DOH prior to placing the distribution pipeline into service. All other water system improvement projects require submittal to and approval by the Washington State Department of Health. A copy of the City's standards is on file at the City and is included in the Appendices to this document. The City uses the current version of the WSDOT specifications and corresponding APWA specifications. Minimum Design Criteria Page 6.8 y . IN N IN e.

It is important to recognize that while the State Department of Health requires that physically independent systems be analyzed separately, the City operates the Port Orchard ("City') System and the 580 Zone ("McCormick Woods') System under one utility. A fundamental element of this Plan is the desire to interconnect the two systems as soon as practical. The analyses presented herein therefore identify system requirements for the existing systems independently. Future improvements, however, are based on the overall plan to connect the two systems as development occurs in the Glenwood JPA, between the City and 580 Zone (McCormick Woods) Systems. This plan for interconnection is supported by the recent (2009) annexation of the McCormick Woods area into the City of Port Orchard and the Department of Ecology's consideration of water rights applications. Ecology has established source of supply requirements and issued water rights for the combined systems servicing the City's overall water service area. The McCormick Wood's portion of the system underwent a detailed analysis that resulted in an amendment to the City's Comprehensive Water System Plan in 2003. It has been reanalyzed herein and is referenced through this document as the 580 Zone (McCormick) System. This reanalysis supersedes the previous Plan amendment and provides for a comprehensive review of the City's complete water system assets. It also provides the requisite analysis for future interconnection of the independent systems and addresses more detailed and current development projections for the western portion of the service area. The analyses put forth herein utilize current (2008) data and the projected growth scenarios through the year 2030 that were established in Sections 2 and 3. The primary focus of the analyses is to determine the type and magnitude of improvements required to meet the projected needs of the anticipated population of the service area. For large scale and costly facilities such as source of supply, transmission lines and storage reservoirs, the ultimate service area needs have been considered to ensure general facility improvements will be of sufficient capacity and location to meet the City's needs well in the future. For distribution system facilities, the primary goal is to develop a more detailed program for to meet the fire flow requirements of current and future development, and the regular renewal and replacements to protect the investment of ratepayers to the system. Transmission, storage and pumping facilities required to connect the City System serving the main portion of the City to the 580 (McCormick) System currently serving the recently annexed McCormick Woods area. As noted, the interconnection is planned to occur "through" the Glenwood JPA area and timing will be dependent on development, possibly as early as 2015. Development in the Glenwood JPA area should be conditional on implementation of interconnecting facilities identified in this Plan. System Analysis C\\ -/\ Page 6-1 City of Port Orchard 2009 Water System Plan 6.2 WATER SUPPLY As discussed in Section 5, the water supply requirements for the City are based on guidelines established by the Washington State Department of Health's (DOH) "Water System Design Manual" dated August 2001. Based on these requirements, the source of supply must be able to deliver water at a rate equal to maximum day demand. For reliability the various sources should be able to replenish lost reservoir capacity due to emergency event, equipment or facility failure within 72 hours (Standby Supply). In addition, it is strongly recommend by DOH, but not required, that fire suppression capacity be replenished from the source of supply within 72 hours also. Tables 6-1 and 6-2 present the available capacity of sources of supply for the City and McCormick systems and provide information regarding water rights capacity as well installed "reliable" capacity. The reliable capacity is based on the available yields from each source of supply provided by City staff. For well sources, 75% of that capacity was used to prevent 24 hour pumping of wells and provide a factor of reliability. System reliability is further ensured by not including emergency interties in the source analyses. This approach is based on the desire to operate the system independent of neighboring jurisdictions. Tables 6-3 and 6-4 present source analyses for the water system(s) through the year 2030. Table 6-3 focuses on installed and actual available capacity (with reliability considerations as discussed above). Table 6-4 presents the source analyses according to existing and projected water rights. The following paragraphs provide an overview of the source conditions and analyses for the City and 580 Zone (McCormick Woods) systems operated by the Port Orchard water utility. 6.2.1 City System As shown in Table 6-3, based on installed capacity and excluding supply from either Bremerton or West Sound Utility through emergency interties, the City system is deficient in source capacity under current and ultimate development scenarios. The addition of the Well 10 in 2010 will greatly improve the source conditions, but a slight deficit does remain. There are two significant concerns related to water supply in the City System. First, the City's wells have experienced declining yields in recent years and are not pumping at full capacity. Secondly, significant expansion to the southern portion of the service area and the development in the McCormick Woods area will require additional supply. To provide for declining well yields and operational constraints and offer conservative estimates it is recommended that the well source capacity (both for pumped wells and artesian wells) be rated on the basis of an 18 hour operating day. The peak well draws typically occur during the driest time of the year when aquifers are low and over pumping can cause silting and future capacity reductions. Overuse of wells during these periods is an important operational consideration. Addressing declining well yields could be resolved by Well 10, a new well that is being developed and expected to be online in 2010. Well 10 is a deep well that was drilled to a System Analysis Page 6.2 \ it" -EI City of Port Orchard 2009 Water System Plan confined aquifer located in the east area of the City, near the waterfront. Testing of Well 10 indicates that as much as 2,000 gallons per minute or more may be available although current water rights are limited to 500 gpm (Qi) and a yearly allotment of 806 Acre -Feet (Qa). This quantity will augment supply from the declining production capacity of existing City wells and help accommodate projected growth throughout the service area. In addition, the well may able to accommodate a transfer of water from wells and water rights in the 260 Low Zone. This may result in a Well 10 capacity of greater than 1,500 gpm with an ultimate design goal of up to 2,000 gpm. Unfortunately, the remote location of the well in relation to existing and proposed development presents challenges with transmission and a new transmission line from east to west is required. The size of the transmission main is estimated at 12-inch diameter and proposed route alternatives are currently being identified in a 2009 engineering study. One alternative is construction of a raw water transmission line from Well 10. along Perry Avenue and ultimately to the Well 6 Site for treatment at an upgraded treatment plant designed to accommodate water from both the existing Well 6 and proposed Well 10. At Well 6, Well 10 water could also be supplied to the 260 Zone as required. Because the Well 6 facilities are in very poor condition, constructing a combined Well 6 and Well 10 facility may be considered. In this case, pumping from this facility would be to both the 260 and 390 Zones as required. Treated water could be routed north and west to an existing waterline crossing of Blackjack Creek. This route would avoid a new crossing of Blackjack Creek, which would be an environmental and permitting improbability. Other alternatives under consideration include: Routing treated water from the treatment plant at the Well 6 site through the downtown corridor and to an existing 12-inch 390 Zone pipeline; Construction of a treatment facility at the Well 10 site, and; Construction of either a raw water or finished water transmission line on a newly constructed boardwalk along the waterfront. Each of these alternatives appear to be more costly than the aforementioned Perry Avenue alternative, which has therefore been used for planning purposes in this document. However, the engineering report and routing study will provide a comprehensive look at the costs and benefits associated with each alternative. Water rights for Well 10 include consideration of the entire ultimate service area population but depending on development, additional wells may be required for the south and western portions of the service area. Improving the ability to transfer water between the 260 and 390 Zones is important to reducing dependency on emergency interties and increasing system reliability. Upgrades to the Melcher Pump Station are instrumental to this and discussed further in Section 6.3. 6.2.2 580 System Source Analysis The 580 System currently consists of the recently annexed McCormick Woods area in the western portion of the City and eventually will be connected to the City System via System Analysis //// Page 6-3 City of Port Orchard 2009 Water System Plan development of the Glenwood JPA. Source of supply to the 580 system is a combination of City owned groundwater wells augmented by water supply from the City of Bremerton. The City is proceeding with consolidation of McCormick Wood Wells 1, 2, and 3 which are currently drawing from a shallow aquifer, to a new well (Well 11) in the deep aquifer. The new Well 11 will result in allocation of an additional 150 gpm (beyond the current 600 gpm) for a total water right of 750 gpm. Construction of Well 11 is proposed for 2009 and will necessitate upgrade of the treatment facility currently serving McCormick Woods Wells 1, 2, and 3. It is anticipated treatment will consist of removal of hydrogen sulfide and chlorination. Room for future fluoridation should be planned, but not constructed at this time due to the agreement with Bremerton that prohibits the possibility of fluoridated water into the Bremerton system discussed below. The existing Interlocal Agreement with the City of Bremerton provides for a maximum of 350 gpm and up to 285 acre-feet per year of uninterruptible supply until such time that the City of Port Orchard can secure new water rights to replace the Bremerton supply. The agreement requires Port Orchard to "make diligent, continuous, and best efforts to acquire water rights to replace Bremerton water." A connection from Bremerton to the McCormick Woods area was established in 2008 to augment supply in the 580 Zone. The supplemental supply is through a recently constructed pump station and 16-inch transmission main up Old Clifton Road. The existing Interlocal Agreement specifically calls for Bremerton to provide an "uninterruptible supply". Provision of supply during a power outage is considered the responsibility of Bremerton. In addition to supplying up to 350 gpm to the 580 Zone, Bremerton utilizes the 580 Zone to supply development lying North of Old Clifton Road that is served by the City of Bremerton. By agreement, Bremerton uses Port Orchard's 580 reservoir to store water for this isolated area of the Bremerton system. Water is metered into the Port Orchard system and out of the Port Orchard system to achieve a net zero water use for the Bremerton Service area. The existing Interlocal Agreement contemplates separation of the 580 Zone and Bremerton systems and construction of an independent Bremerton storage facility on the Port Orchard 580 Zone reservoir site and at the writing of this plan, negotiation of easements to accommodate this are under negotiation. The exchange of water with Bremerton through the 580 Zone is complicated by the fact that the Interlocal Agreement prohibits introduction of fluoridated water into the Bremerton water system. The City of Port Orchard currently fluoridates water from all sources except the wells serving the McCormick Woods area. As the City proceeds with interconnection of the City System and the 580 Zone and replaces Bremerton supply to the 580 Zone, fluoridated water will be introduced to the 580 Zone. When this occurs, Port Orchard will need to provide notice to Bremerton that independent storage and transmission facilities will be required to serve Bremerton customers north of Old Clifton Road. Alternatively, the agreement as it relates to fluoridation could be modified to remove this limiting factor to the development of the 580 Zone System. System Analysis ^ Page 6-4 `PAICC/ City of Port Orchard 2009 Water System Plan Source deficiencies in the 580 Zone are indicated after the year 2020, primarily due to development within the Glenwood JPA, and will be corrected by a combination of transferring water from the City system to the 580 Zone via the Glenwood JPA, and development to future sources in the 580 Zone. As development in the Glenwood JPA area occurs, implementation of the interconnecting facilities identified in this Plan should be constructed. The City has applied for but withdrawn an application for new water rights at the 580 Zone reservoir site. The need for a new well, improved transmission and/or transfer of water rights should 2030 all be considered as development proposals become more clear.

The City is seeking replacement of that supply in accordance with the terms of an Interlocal Agreement. System Analysis Page 6.8 CFWCC City of Port Orchard 2009 Water System Plan 6.3 PUMPING There are three pump stations in the City System and one in the 580 Zone (McCormick Woods) System. Evaluations of facilities within each system are presented below: 6.3.1 City System Pumping Analysis The two pump stations serving the City System were evaluated using all three criteria established by DOH and discussed in Section 5. Both stations were of adequate capacity under current conditions and configuration but the City Hall Pump Station is antiquated and in need of rehabilitation. One option would be to eliminate it and transfer water rights to another well in the system. Regardless of the transfer of water rights, bringing Well 10 online will require upgrade of the Melcher Pump Station to accommodate a third pump for transfer of Well 10 water into the water system west of Blackjack Creek. Well 6 has an artesian flow with a head of about 5 psi. The well discharges to a clear well to remove hydrogen sulfide, and is then treated with chlorine and fluoride prior to being pumped into the system. Only one pump is available, and no standby power exists at this site. All of the facilities are old and need major upgrading. One option to accomplish this would be to pump Well 10 water to the Well 6 site and construct a new storage clear well and treatment for both wells. A pump station could be constructed to pump the combined water to both 260 and 390 Zones as required. 6.3.2 580 Zone(McCormick) System Pumping Analysis The McCormick Wood's 580 Pump Station is of adequate capacity to meet the immediate service area needs of the McCormick Woods Development. However, treatment to include hydrogen sulfide may need to be added for the proposed new Well 11 developed in 2009 to replace McCormick Wells 1, 2, and 3. In order to provide water from Well 10 to the 580 and above pressure zones, a new transfer pump station will be necessary to the transfer water from the 390 Zone to McCormick Woods 580 Zone. In addition, this station will provide water for the future development of in the 580 Zone and Glenwood Road JPA areas. Based on the results shown in Table 6-2 there is a source shortage in the McCormick Woods area in 2011 and 2025. Additional water rights have been applied for and will be sufficient to make up for the future deficiency (proposed Well 12). However, there is no guarantee that these additional water rights will be approved, and is uncertain whether this request is still active. Also, the City, with this pump station, will be able to provide a second source of water to the 580 and 660 Zones. The recommendation is to design a transfer pump station with two 650 gpm pumps with room for a third 600 gpm pump that would be necessary if the additional water sources are System Analysis Page 9.9 City of Port Orchard 2009 Water System Plan not developed in the 580 Zone. This will also provide for the largest pump to be out of service as well the capability to provide an additional source of supply to the area. A detailed engineering report will be required prior to final design of the required facilities. 6.4 STORAGE ANALYSIS The recommended storage capacity for a water system per DOH and minimum requirement established for the City of Port Orchard is equal to the sum of the equalizing, standby, and fire suppression storage. Each of the storage components are described below. Table 6-3 shows the existing and projected storage requirements for the City and 580 Zone Systems independently. 6.3.1 City System Storage Analysis Storage facilities serving the City system are detailed in Section 4 and include a total of 4.25 million gallons of storage in six separate reservoir. Three reservoirs (Park, Morton Street and Maple Street)serve the 260 Zone with 2.15 million gallons of storage. The other three reservoirs (South Sydney, Old Clifton and Sedgwick) provide the 390 Zone with 2.1 million gallons of water. The 390 Zone reservoirs also serve a small service area that is fed through PRVs and operates as an Intermediate Zone at a Hydraulic Grade Line of 336. THE characteristics of available storage are indicated on Table 6-5. As indicated there is a deficit in 390 High Zone storage currently but and through the planning horizon of 2025. Consideration of a small -pressurized zone to serve the higher elevation immediately surrounding the Sedgwick Tank would rectify the problem by reducing the dead storage quantity. Automatic interties with pressure reducing valves from the 390 High Zone to the 260 Low Zone are also recommended to alleviate this issue and improve system reliability through increased availability of standby storage. 6.3.2 580 Zone(McCormick) System Storage Analysis Three reservoirs currently serve the 580 (McCormick) System. A total of .57 million gallons of storage is provided in the 580 Reservoir (0,45 million gallons and McCormick Woods Tanks 1 and 2 (0.06 million gallons each). The storage deficit shown for McCormick Woods which includes only McCormick Woods West and Glenwood JPA areas is anticipated due to growth in the immediate area, especially in the Glenwood JPA. The projections, however, do not include the McCormick Woods North or areas served by the City of Bremerton. An additional 1.7± million gallon reservoir of usable storage is proposed to satisfy the deficit outlined in Table 6-3. Based on the results shown in Table 6-2, additional source would be required to serve the McCormick Woods West and Glenwood JPA area. Although additional water rights have been applied for (Well 11), the current applications may not be sufficient to meet the ultimate development capacity of the area and there is no assurance that the water rights will be granted. Therefore, in order to provide a future source of water to the 580 and above System Analysis Page 0.10 City of Port Orchard 2009 Water System Plan zones, a new transfer pump station would be required form the City's 390 Zone. The new pump station would supply proposed development in the Glenwood JPA and augment supply to the McCormick Woods and McCormick Woods West areas. It is recommend that the pump station be sized for installation of two 650 gpm pumps with additional space provided for a proposed third 600 gpm pump in the event that an additional source is not constructed within the 580 Zone. This will increase capacity and reliability to serve the area in the event that the largest pump is out of service.

This particular software allows graphical representation of the water system within the AutoCAD working environment. With this analysis tool, various modifications, parameter changes, and improvements can be easily evaluated. Thus, the identification of problem areas and the development of possible solutions are expedited. By having the water system model on the computer, developer extensions, and other improvements can be modeled as they occur, allowing design and construction of the most effective and cost efficient system. Version 6.0 of the H2O Net software was used for water system analysis. The program has the capability to simulate all components of a water system, including pipes, pumps, pressure reducing valves, and reservoirs. This includes the previously calibrated McCormick Woods water system model that was received from a separate consultant, converted from Water CAD to H2O Net, and integrated with the City's model. This provides one model that can be used to analyze the entire water system. The City's water system model involves the use of approximately 475 pipes and 400 nodes. Nodes serve as connection points for pipes and can be assigned external demands to simulate water uses within the system. All metering points, pumps, pressure reducing valves, and reservoirs are also included in the model. Output reports from the model can indicate high or low node pressures and pipe velocities. To express flow in pipes, the Hazen -Williams equation for turbulent flow as a function of pipe length, diameter, head loss, and roughness was used. H2O Net software allows the user to enter all necessary attribute data needed to model the pipes. In addition to assigning external demand data for each node, pressure reducing valve downstream pressures, and tank elevations during fire flow testing were input. 6.5.2 Hydraulic Model Calibration In order for the hydraulic computer model to accurately reflect the operation of the water system, it must accurately model all facilities in the existing water system. After all water facilities were accounted for in the model, demands were evenly distributed between nodes in their associated pressure zone. A point demand was established from water use data for 17 individual accounts demonstrating high water use to better represent actual flow through the system. The remainder of demand was spread equally throughout the system according to general land use and population characteristics. To verify that the hydraulic model was accurate and closely replicates the current operation of the existing system, information from fire flow tests were collected by the City prior to this planning effort. However, because no specific testing was accomplished as part of this System Analysis /\ /\ Page 6.17 City of Port Orchard 2009 Water System Plan Plan, and because the City operates its reservoirs within a very small range (two feet) assumptions were made regarding tank levels during the time of the fire flow tests. With this data, scenarios were created in the hydraulic model with water system facility parameters set to the reservoir levels that occurred during the fire flow tests. After running simulations, slight adjustments were made to the minor head losses for the various components of the water system model until the modeled fire flows and static pressures matched those of the actual tests. Test static pressures and modeled static pressures calibrated to approximately 10% in all instances. In general, inconsistencies may be attributed to slightly incorrect elevation data. Tested fire flows and modeled fire flows also showed significant correlation. 6.5.3 Hydraulic Analysis The model was used to determine areas where system deficiencies exist, or are likely to develop, under various flow conditions. These deficiencies include areas of high or low pressure, areas with high flow velocities in the pipelines, and areas with low available fire flow. The system was analyzed using the minimum design criteria put forth in Section 5, which are based on recommended Department of Health criteria. Present and future conditions were analyzed using the following pertinent design criteria: • Steady state analysis and conditions. • An acceptable pressure range of 40 psi to 100 psi for domestic flows. • A minimum system pressure of 30 psi throughout the City under peak hour demand conditions. • A minimum system pressure of 20 psi under maximum day demand plus required fire flow conditions. • A maximum pipeline velocity of 12 feet per second under fire flow conditions. The analysis was performed assuming supply from the reservoirs only and the Melcher Pump Station inactive. System modeling was completed with the reservoir elevations set at the average of the operational storage component, so only the effective storage was considered. • By using these criteria, existing and potential issues were identified and are discussed below and presented in the Capital Facilities Plan. System Analysis Page 6-18 City of Port Orchard 2009 Water System Plan 6.5.4 Pressure Evaluation The following scenarios were modeled: Average daily demand (ADD) and maximum daily demand (MDD) for current water usage and that of future years 2010 and 2025. The results indicate that the water velocities in all of the modeled pipes are within acceptable limits, i.e. less than five feet per second (fps), for each scenario. Concerning pressure, the results indicated that for all scenarios, system pressures fell generally within the specified working range of 40 to 100 pounds per square inch (psi). Results that were above or below this range were mainly a function of the City's varied ground elevations. 6.5.4.1 City System Pressure Analysis Specific observations related to pressure are summarized below: Pressures below 40 psi were observed in an 8-inch diameter main on Taylor Street between Cline and Sidney Avenues. In addition, lower working pressures were observed in the 4-inch diameter mains on Dwight Street between Sidney Avenue and Kitsap Street. To facilitate fire flows, it is recommended that the City upgrade these 4-inch mains to 8-inch diameter pipes as part of any long term Capital Improvements Plan (CIP) they have in place. Pressures above 100 psi were observed in the 8-inch diameter main feeding the Eaglecrest Neighborhood, in the 12-inch diameter main from Old Clifton Road where it crosses under Highway 16, on Bay Street along the length of the waterfront; and in 6 and 8-inch diameter mains in the areas bounded by Bethel Road on the west, Sroufe Street on the south, Mitchell Avenue on the east, and ending at South Kitsap High School. All these pipes are modeled as being fed by the 12-inch diameter main on South Street. In addition, high pressures were observed in the vicinity of Perry Avenue and Tracy Avenue in the old section of the City. To reduce system pressures in these areas of the City System, the following upgrades are recommended: • Install pressure -reducing valves (PRVs) at the Eaglecrest Neighborhood (on Eaglecrest Place near Melcher Street) and on the 12-inch main near the intersection of Kendall and Maple Streets. • Reduction of pressure to working limits along the waterfront on Bay Street would require the installation of four to six PRVs and the creation of a third pressure zone. Therefore, unless the City is experiencing significant problems, it is not recommended that these upgrades be performed. The high pressure observed in the 12-inch main under Highway 16, is a function of local elevation of the pipe, and does not need to be reduced. system Analysis Page 6-19 V c ° O 2 2m U N N > 2 r N Y L CL H Ln c c +p+ -p L y C a3 L N a (0 a) a O as c rn _a 3 > (0c 2 > N J a\ a N CA o C -O L r o j N N m a CCa a a1 @ a) Y p' a) O a U ¢ >,W CC C L L (n ul p m c N d U) a m 3 N y c c 0" N N N 0 m Y CL `0 0 CO 0 y N a1 C (OD) O U) C C N (n > 2 U/ a t N LC • c jp 'c L C,w a� ' « lL O L a) o = O O a5 3 F U a p ° o 0 a (A ° 0 E N v F E d` ° o. c' as m 3 u o .� T ai a o 3 �0 o. a� ao -0 a C7 m c c > Q -o m o f (7 o V o C7 m Q m c �� o o _p_ a O °> Cc s N o m a (n o U) a o— as ccc: m o c m OCI ` c p Y— T @ C CL " C c a (D CL m CD Ol N Uf% W POD') L a) 3 N U 3 -Op a a s E W p N a) c c O CL a SCL C - @ c c ° Q r CA C N C 'E tL o c 0 .0 Y U) �- L 0 O C a) E ` 0 J N 2 E E L 0 E c c o y CO LL a 10 m 3 = Q) 0 p O ° c 10 O 0 0 0 0 -0 t p E a 0 N a0+ N .0) -o c� N a a n a m a a a a 8 10 a E LL 'm 'm 'm c� 0 0 r m 'a 'a 'a 'a 'a o 'a 'a a E s n U c c Cl v L E E E' o '- jp L L L L L L L L L L m U L 3 U L L L C O O O p U U U U U U U U U U O c U m c U U U L CO— 0 -� c c c c c c c c c c o c a 3 c c c a, N N N N N v co v v co c° co co co to ro Cl) o (0 W� Q H H r F-- F o2 ao w y T w 'o Cc o O N N c p a c d N U a T (n c a) p �UQ a E mU) >� �@ m 0 a 0 2 0 m aC p Y a @ a N p 3 to Un F m c Q O c c c 3 16 c a a1 0 = cf) af6i 3 •� c o c �, 3 a) (V d 6> tG a o o Q) o f > J N m U 7 0 'O N U) T Q Un c c U c E a U C ID Q) c a° N c N 0 m a E a) 00 a C 3° ° c O °c rn U U) a N a, N a N m N c >,C) O o o N 0 y a o a C V OI N W N U C N J E 'V _ �% W N F O N a c d E U d 3 a E 3 _m a L c c a a z J a) J L U N C L U L L Z V H H H CO 0 H t0 m H (O N m C] E pp uoi o 0 {p O IM N (d Epp} O O 0 V O O O CV cM LL LL City of Port Orchard 2009 Water System Plan 6.5.4.1 580 (McCormick) System Pressure Analysis Within a small area of the 580 Zone, modeled pressures are as high as 120 psi for a few customers. The high pressures affect only a few customers and individual PRVs are recommended to resolve the issue. Low pressures are anticipated in the vicinity of the McCormick Woods West development. To provide system pressures in the 40 — 100 psi range, a closed booster pump station is proposed for construction as a condition for development to occur in this area. The installation of this booster station will create a new City 660 Zone for service.

The minimum pipe diameter modeled for the analysis was 4-inches and fire flow demands for specific node classes were as specified by Uniform Fire Code and Insurance Services Office (ISO) guidelines. The analysis indicated generally that adequate flows were available for all pressure zones, but that some deficiencies are present. The minimum pipe diameter modeled for the analysis was 4- inches. In addition, it was assumed for all analyses that the Melcher Street pump station was off, no wells were actively pumping, and the connection to the Bremerton system was closed. Critical pressure for nodes in all the fire flow analyses was set at 20 psi. The model tests were also run with all pumps turned off to assess the ability of the system to operate with supply only from storage reservoirs. To determine the general availability of fire flow in the system, an initial fire flow demand of 2,000 gpm was applied to every node in the City of Port Orchard's system and 1,500 gpm to every node in the 580 Zone. Individual zones were then modeled separately at flows ranging up to 4,000 gpm within the City of Port Orchard, along with individual high users. Fire flow demands for individual high users were as stipulated by the ISO guidelines. The results of the fire flow analysis indicated generally that adequate flows, up to 4,000 gpm, were available for all of the City pressure zones and 1,500 gpm in the 580 Zone. Figure 6-2 shows available fire flows, as determined by modeling, throughout the City under current MDD conditions. Fire flows of 1,500 gpm are available in the residential portions of the 580 Zone and approximately 2,700 gpm at the Club House. A number of areas were observed to have deficiencies, i.e. node pressures dropping below 20 psi during fire events. 6.5.5.1 City System Fire Flow Analysis A general summary of High and Low Zone results for these areas is presented below. Available Fire Flows of less than 1,000 gpm are found at dead and closed pipe ends, in pipes with diameters of less than 6-inches, and in the vicinity bound by Central Street on the north, Mitchell Avenue on the east, Sroufe Street on the south, and Rockwell Avenue to the west. In addition, the Intermediate Pressure Zone has nodes that are not capable of a 1,000 gpm flow. At the South Kitsap High School, the 8- inch diameter High Zone main that dead -ends there was found to have a flow of 2,000 gpm. System Analysis Page 6-22 P� ACE City of Port Orchard 2009 Water System Plan The Eaglecrest Neighborhood, the Intermediate Pressure Zone area, and the 6-inch diameter mains on South Flower Street and Goldenrod Street have fire flows below 1500 gpm. Potential problem areas were revealed in the with the 6-inch pipes in the southeast and at the northeast corner of the High Zone that includes Bethel Road and Mitchell Avenue. Specific areas of the Low and High Pressure Zones were listed previously in Table 6- 6 with the accompanying fire flow ranges at which residual pressure was observed to decrease below 20 psi. The following paragraphs presents a summary of the analysis performed to determine availability of fire flows at specific facilities requiring high fire flows: City System — 390 High Zone: South Kitsap High School: this node can only flow 1,500 gpm, and so a separate fire line would have to be run from the nearest Low Zone hydrant (at least 300 ft away) to get the remaining 2,000 gpm necessary to reach the 3,500 gpm typically required for schools. Upsizing pipes may be needed to obtain a 3500 gpm Fire Flow and completion of this well with the Well 6 project will help increase flows this area. Hi Joy Bowl: this node can only reach 2,400 gpm of the required 3,000 gpm for commercial facilities. In addition, nodes in the Bethel/Mitchell area sequentially show residuals pressures below 20 psi through the connection with the 12-inch diameter main from South Street to the Melcher Pump Station. The Pancake House and South Kitsap Mall are located on the same mains and experience the same problems. Group Health: this node can only reach 2,500 of the required 3,500 gpm for institutions. Peninsula Work Release: this node on Lloyd Parkway can meet the required 3,500 gpm of an institution but when this demand is applied, nodes north of this location have residual pressures at or below 20 psi. Shari's Restaurant: 3,000 gpm fire flow on this node on Sedgwick Road causes pressure to drop slightly below 20 psi. However, this area typically has low pressure due to its proximity to Tank 5 and so this is not considered to be a significant problem. System Analysis Page 6.23 City of Port Orchard 2009 Water Svstem Plan City System — 260 Low Zone: The High Users in this area are Holiday Inn Express, Kitsap County Admin Building (J160), and Tweten's Lighthouse Restaurant. All of these nodes can reach 3,000 gpm as required by code. However, nodes in the Intermediate Zone and areas near the Melcher Pump Station that are connected to the Low Zone drop below 20 psi residual pressure. In addition, the 4-inch diameter pipe located between Dwight and Kitsap Streets drops below 20 psi at the fire flow demand on the above users. A maximum flow for these nodes, the High Users, is approximately 1,500 gpm. Analyses of fire flow results indicate that several areas in the existing water system have velocities above 12 fps during fire events. These areas are primarily along Bay and Kitsap Streets in the Low Zone and in the Bethel Road and Mitchell Avenue areas in the High Zone. 6.5.5.2 580 (McCormick) System: Within the 580 Zone, available fire flows of less than 1,000 gpm were observed at dead ends, in pipes less than 8-inches in diameter and areas where transmission or main distribution piping capacities are inadequate. The high user in this area is the McCormick Woods Clubhouse. Under the build out MDD scenario, the Clubhouse can maintain a fire flow of approximately 2,700 gpm while maintaining a minimum 20 psi pressure within the overall water system. System Analysis Page6-24 6QC Insert Fire Flow Map City of Port Orchard 2009 Water System Plan System Analysis Page 6.26 of Port Orchard i Water Svstem Plan System Analysis Page 6-26 City of Port Orchard 2009 Water System Plan Areas of inadequate fire flow within this zone can be attributed to long dead end water mains, undersized water mains, and lack of global and localized water main looping. 6.5.5.3 Fire Flow Improvements Improvements in fire flow to meet future demand conditions consists of replacing existing 4 and 6-inch diameter mains with a minimum of 8-inch diameter mains, looping water mains, and installing interties to connect to the water system of adjacent water purveyors. The general areas identified for fire flow improvements include City System: • The area bounded by Dwight Street on the north, Mitchell Avenue on the east, Sroufe Street on the south, and Rockwell Avenue to the west. • The Eaglecrest Neighborhood. • The Intermediate Pressure Zone. • 6-inch mains on South Flower and Goldenrod Streets. • 4-inch pipes in the downtown area of Port Orchard. • 4-inch main running from Pottery and May St. to Sroufe St. and Sidney Ave. • 6-inch main terminating on Granat Street. • 4-inch mains on Hull and Division Streets. • 4-inch mains on Dwight and Seattle Streets. • 4-inch main on Turnberry Place Southwest. • 4-inch main on Killeen Place Southwest. • 4-inch main on Southwest Gilway Court. • 4-inch main on Kinfig Place Southwest. • Two 6-inch mains south of St. Clare Drive Southwest (P-114 & P-115). • 6-inch main east of Hawkstone Avenue Southwest. • 8-inch loop south of St. Clare Drive Southwest. • 8-inch main on Baltray Place Southwest. • 8-inch main Broadstone Place Southwest. • 8-inch main east of Turnberry Place Southwest. 580 Zone (McCormick) System: • 6-inch main northwest of McCormick Woods Reservoir. • 6-inch main northeast of McCormick Woods Reservoir. • 4-inch main west of McCormick Woods Reservoir. • 4-inch main on Ashridge Avenue Southwest. • 8-inch main on Southwest Dunraven Court. System Analysis Page B-27 City of Port Orchard 2009 Water System Plan 6.5.8 Small Main Replacements It is recommended that the City embark on a small water main replacement program to be implemented over a number of years and in conjunction with new development, street overlays, and sewer system improvements. This will improve flow and accommodate for future demand capacity. A summary of recommended small water main replacements is summarized below: City System: The 4-inch diameter water mains in downtown Port Orchard, including the following pipes should be replaced with 8-inch mains: • The 4-inch line that connects from Sherman Avenue to Cline Avenue. • The 4-inch line that connects from Dwight Street to Kitsap Street. • The 4-inch line that connects from Sidney Avenue to Bay Street. • The 4-inch pipe running from Pottery Road and May Street to Sroufe Street and Sidney Avenue. • The entire 6 and 8-inch main network feeding off of the 12-inch main at Maple Street and serving the Bethel and Mitchell High Zone area. • The 6-inch water main on Bay Street should be upgraded to a 12-inch diameter pipe. • The 6-inch mains on South Flower Street and Goldenrod Street. 580 Zone (McCormick) System: Small mains recommended for replacement within the 580 Zone of McCormick Woods are listed in the Fire Flow Improvements Section above. In the event of property rezoning, the system may not be capable of meeting the increased fire flow requirements. If this is the case, the water mains will require re- examination to determine necessary improvements. It is recommended that the City monitor new construction and rezoning activities in the interest of fire protection. 6.5.9 Analysis of CIP Alternatives The following CIP Alternatives were modeled to assess their impact upon system fire flow capacity. The alternatives are as follows: Alternative 1: Installation of PRVs to interconnect the High and Low Zone. Alternative 2: Installation of New Well #10 (assumed flow range of 1,000 to 1,500 gpm) and accompanying 12-inch diameter transmission main along Perry, Bay, Rockwell Streets, and Cline Avenue. System Analysis Page 6-28 City of Port Orchard 2009 Water System Plan The analysis of benefit comparison for the two CIP options based on available fire flows was conducted separately on the High Zone (including Intermediate Zone) and Low Zone. Results for Alternative 1 indicated that fire flows in the old town area of the City were increased by the installation of PRVs at Maple and Kendall Streets and at Dwight Street and Mitchell Avenue. In addition, the analysis indicated that Low Zone fire flows were increased by the installation of a PRV at the intersection of Pottery Road and Melcher Street. For Alternative 2, Low Zone fire flows were observed to have an average improvement of approximately 34% (1,000 gpm). In particular, fire flows in the vicinity of the waterfront area were found to increase as much 70% over existing flows. In addition, fire flows in the High Zone improved by an average of 10% (170 gpm) when Alternative 2 was modeled. 6.5.10 Interconnecting the 580 Zone and the City's System A plan is proposed to extend a 12-inch main beginning at the intersection of Sidney Road SW and SW Sedgwick Road to the southwest through the Glenwood Road JPA area and then west to the McCormick Woods Loop Road (10-inch main). The elevation along Sedgwick Road is approximately 300 feet and a booster station would need to be constructed with an initial pump capacity of 650± gpm (2 — 650 gpm pumps and with a future capacity of 1,200± gpm). The station would transfer water from the 390 Zone to the 580 Zone. The future size of the pump station will depend on if additional wells are developed at the 580 Reservoir site. Additional analysis is recommended at the time of design to identify a specific pump station location and other design parameters. An alternate booster pump station location is possible but would require a longer transmission main would be required, consequently making this the more costly alternative to the proposed alternative presented above. 6.5.11 New 660 Pressure Zone In order for development to occur above elevation 478'- 480'±, a constant pressure booster station will be required. The station will be required to operate for all flow conditions including from 0-1,500 gpm fire flow and have standby power capabilities which would allow continuous operation in the case of a power outage. The booster station will pump from the 580 Zone storage facilities into a new 660 distribution system. 6.5.12 Additional 580/660 Zone Reservoir As shown in Table 6-2, there is a proposed 1.1 million gallon storage deficit based on the 2025 projections for the McCormick Woods area. This includes the McCormick Woods West and Glenwood JPA areas and the new 660 Zone service area. To eliminate this storage deficit, a new 1.1 million gallon reservoir is proposed at the City's 580 Reservoir site. The reservoir height should be the same as the existing 0.57 million gallon reservoir. n Analysis Page 6.29 City of Port Orchard 2009 Water System Plan 6.5.13 Melcher Pump Station Upgrade In order to allow for the possible transfer of water from the City's Low Zone to the 580 Zone, significant improvements are needed at the Melcher Pump Station. Pumping capacity of the station should be increased by a minimum of 650 gpm which would allow for the transfer of water to the 580 Zone. This improvement may not be needed for some time if water from Well 10 is pumped directly into the 390 Zone. Additional flow may be needed depending on the development of any new wells at the 580 Zone Reservoir site. Based on Table 6-1, the Melcher Pump Station should be increased to approximately 1,300 gpm unless Well 10 water is pumped directly to the 390 Zone system. This could be reduced by the amount of additional water from wells developed in the 580 Zone. 6.5.14 Hydraulic Analysis General Conclusions: The current water system is sufficient to handle domestic use ADD and MDD flows through 2025 while generally maintaining working pressures above 40 psi. Pressures below 40 psi exist at higher elevations near tanks as to be expected, on the 4-inch diameter pipes modeled in the Low Zone, and through the entire Intermediate Pressure Zone and the Melcher Pump Station feed line. These areas become problems during fire flow events and may require larger diameter mains, 8-inch diameter minimum, to be installed as the City upgrades its water system. Based upon fire flow results, the Bethel Road and Mitchell Avenue sections of the High Zone may need larger or additional looping of water mains to maintain 20 psi residual pressures while providing adequate flows. Specifically, an 8-inch diameter looping main could be installed from the 12-inch diameter main on Kendall Street south and through the existing loop to connect to the 8-inch main at Plisko Lane and Mitchell Avenue. The Melcher Pump Station may also be able to alleviate this area in the event of a fire flow. Primary distribution mains within the 580 Zone are generally large enough to supply fire flow capacity to the rest of the distribution system. However, areas within the 580 Zone will require future looping and upsizing to meet required fire flows. Future water main extensions should be analyzed on a case by case basis to determine adequate pipe capacity. A general replacement plan for smaller diameter mains in the north section of the Low Pressure Zone should be implemented. After replacement of the mains in this area has taken place, smaller diameter mains in the eastern and southern portions of the High Pressure Zone should be replaced. A general main replacement plan should be implemented in the 580 Zone in addition to the construction of a future reservoir. The 6-inch diameter lines in the southeastern portion of the High Pressure Zone may need to be replaced by 8-inch lines depending on the local uses or any prospects for future commercial or industrial growth. System Analysis Page 6-30 k City of Port Orchard 2009 Water System Plan 6.6 SYSTEM ANALYSIS OVERVIEW — LIMITING FACTORS In summary, the biggest challenge facing the City of Port Orchard is meeting the needs of future development while maintaining sufficient yield from its permitted supply. While water rights are sufficient to meet both near and long terms needs of the City, the ability to withdraw, treat and supply water is currently limited. Construction of Well 10 supply, treatment and transmission is critical to alleviating the declining supply yields from existing wells. Consideration of additional water rights at and/or transfer of rights to Well 10 may become equally important if yields from other wells continue to decrease. Another critical consideration for operating and regulatory simplification is combining the two water systems into one system. While construction of additional storage and continued use of the Bremerton supply to 580 Zone provides an interim solution, development of the Glenwood JPA cannot occur without an intertie between the City and McCormick Systems. This will bring additional supply to 580 Zone, allow for integration of the systems, provide operating independence, improve reliability and reduce paperwork, testing and confusion associated with operating under two separate water system Identification numbers. Lastly, portions of the City Water System will soon approach the end of their useful life. Funding for needed upgrades and replacement of the aging water infrastructure is needed to improve fire flows, replace undersized mains and take a proactive approach to renewals and replacements prior to more costly replacements following facility failure. An aggressive approach to acquiring funding from current Economic Recovery program grants, low interest bonds or low interest loans is recommended and discussed further in Section 10. System Analysis CPACE Page 6-37 e SECTION 7 CAPITAL IMPROVEMENTS PLAN 7.1 OBJECTIVES Previous sections of the Plan have concentrated on projected demographics with the City and service area, evaluation of existing facilities in relation to these projections and identification of recommended systems improvements. This section presents, in summary form, the recommended future water system and system improvements for the area currently served by the City. It is noted that specific projects for Developer Extensions or new developments are not included in this CIP and will be determined at the time of application for water availability. The objectives of the improvements plans are to group various .system needs, to evaluate alternatives that are cost-effective and operationally sound, and then to organize and prioritize the recommended improvements for implementation by the City in its annual budgeting process. 7.2 PROJECT COST ESTIMATES AND SCHEDULES In order to provide long range planning of proposed water system improvements, detailed cost estimates are required. These cost estimates are based on a variety of factors, including: documented costs of performing similar kinds of work in the recent past; engineering judgment; the availability of labor; the time of year of construction; competitive conditions; and other intangibles affecting construction costs at the time that the work is performed. The planning level estimates provided in this Plan are intended to be conservative estimates which will be refined during the design process. It is important to realize that the actual design of the improvements and possible changes made during that design could significantly alter the cost of the project from the estimate shown. Prior to the initiation of the projects shown in the Plan, any changes should be reviewed and the cost estimate updated to reflect current conditions. The cost estimates presented in the Water System Capital Facilities Plans, are based on 2008 prices (Engineering New Record Construction Cost Index of 8680.0.) and reflect total project costs. These costs include construction costs plus a contingency of 10 percent and overhead costs such as project administration, engineering, legal fees, taxes, etc. Overhead costs have been computed at 35 percent of construction cost. 7.3 CAPITAL FACILITIES PLAN The combined Capital Facilities Plan for the City is presented in Table 7-1. Specifics on the water system improvements are contained in Section 6 of this Plan and the brief summary that follows. A tentative schedule for improvements, by year is put forth in Section 10. CCapital Improvements (\\\ 111\ Page 7-1 City of Port Orchard 2009 Water System Plan Project 1 Telemetry Upgrades This project includes various upgrades of old telemetry equipment at the various well and reservoir locations. A detailed analysis is recommended to further define the scope of the needed improvements. Project 2 Well 11/Treatment Upgrades This project includes the drilling of a new deep aquifer well that will produce 750 gpm, installing a well pump and controls, modifying treatment to include hydrogen sulfide removal, and reusing the existing chlorination system. Because the well would also serve the Bremerton service area, fluoride would not be initially added, but room would be left to add Phis in the future. McCormick Wells 1, 2, and 3 would be eliminated. Two small reservoirs could be utilized as a clear well and facility where aeration of the water could occur to remove hydrogen sulfide from the water. Project 3 Well 10 In order to activate this new well, a well pump with controls and piping is needed. It is anticipated that a small building will be constructed to house the well, on -site generator, and controls. On - site piping would include a 12-inch pipe to connect to the Well 10 transmission main (project 5). Additionally, on -site drainage will be provided. The site is expected to be landscaped for public use. Project 4 Wells 6 and 10 Treatment Improvements This project combines treatment for the new Well 10 and the upgrade/replacement for treatment of existing Well 6. The new facility will be constructed on the Well 6 site. Treatment will include hydrogen sulfide, chlorination, and fluoridation. A pump station will be constructed to deliver water to both the 260 and 390 Zones as needed. Project 5 Well 10 Transmission Main This project includes the design and construction of a transmission main to deliver water from the Well 10 site along Perry Avenue North, Bay Street, and Maple Avenue to the Well 6 site. From the Well 6 site, the transmission main may head west and south along the west side of the cemetery to the extension of Kendall Street and connect to a 12-inch, 390 Zone main at that location. Final design will determine actual final location of the main. Project 6 PRVs High to Low Zone This project involves installing three PRVs to provide connection between the 390 and 260 Zones to improve storage for its 260 Zone, circulation, and water quality. Capital Improvements Page 7-2 L, City of Port Orchard 2009 Water System Plan Project 7 City Hall Pump Station Elimination/Well 7 Treatment Because of reduced and minimal flows, the City desires to eliminate Wells 4 and 5 by transferring water rights to Well 10. By installing treatment for Well 7 at the well site, or alternative locations, City Hall facilities can be abandoned. This facility is in need of upgrades if it is to remain in service. The budget for this project needs to be verified once a final scope is determined for this project. The preliminary budget contained in this Plan assumed the abandonment of Wells 4 and 5 and elimination of Well 7, which will allow for the abandonment of the structure of this site. Also included is the on -site treatment of Well 7 to eliminate the treatment of Well 7 on the City Hall site. Project 8 1.7± Million Gallon 580 Reservoir This project includes the construction of a new reservoir sized for ultimate development in the 580 and 660 Zones. Preliminary studies indicate the reservoir should have about 1.7± million gallons of usable storage. Project 9 390 to 580 Booster Pump Station This project includes construction of a 390 to 580 transfer booster station as described in section 6.3. The initial pump station includes two (2) 650-gpm pumps with room for a future 600-gpm pump. This size needs to be verified based on final location and elevation of storage, as locating storage for the 580 Zone at a lower elevation will require upsizing this pump station. It is assumed that the station will be constructed as development requires it. Project 10 390 to 580 Transmission Main This project would provide a pipeline to transfer water from the City's 390 Zone to the McCormick Woods area. It would be constructed by development as required. Project 11 580 to 660 Constant Pressure Booster Station This project involves construction of a water booster station that would pump from the City 580 reservoir(s) to the new 660 Zone. This station would need to provide for both peak hourly demands and fire flow demands for the 660 Zone. The facility will require complete backup power. Project 12 Melcher Street Pump Station Upgrade This project includes installing additional pumps and controls to accommodate the added transfer of water from the 260 Zone to the 390 Zone. The final configuration of the Well 10 transfer of water to the 390 Zone will determine the need and timing of this project. Capital Improvements Page 7-3 City of Port Orchard 2009 Water System Plan Project 13 390 Zone Storage Section 6.4 discusses the existing and future storage shortage in the City's 390 Zone. Several alternatives are available to correct this shortage. These include: installing pumping and standby power to pump the dead storage and make it usable; constructing a small pressurized zone to serve the high area around the Sedgwick tank. This would allow the water elevation in that tank to drop further eliminating some of the dead storage and increasing the available storage; or, additional storage could be constructed (250,000 gallons) with most of it near the 390 elevation. This may require an elevated tank. A detailed study of these options would be needed to assess the most cost-effective alternative. As a further alternative, West Sound Utility District has contacted the City to see if the City would be interested in a joint use reservoir being constructed on the City's Sedgwick Reservoir site. If sufficient storage were available from a joint use reservoir at the needed elevation, this may provide a viable option. Because of the many options available, we have provided a budget of $500,000 for this project. A final budget would be set up after a study is completed to evaluate the options. Projects 14, 15, and 16 Water Main Replacement Program These multiple main replacements are discussed in detail in the Plan and detailed on Tables 7-1 A, 7-1 B and 7-1 C following the CIP.

EPA has delegated primacy (primary enforcement responsibility for water quality) to the State of Washington under the provisions of the federal Safe Drinking Water Act (SDWA). In order to maintain primacy, the state must adopt drinking water regulations at least as strict as the federal regulations. In 1974, the SDWA was enacted, requiring EPA to set enforceable health -related drinking water quality standards for all public water systems (PWSs) serving 25 persons or more. EPA set interim standards in 1975 based upon the 1962 USPHS guidelines. The health -related standards, also known as National Primary Drinking Water Regulations (NPDWRs) or "primary standards," set maximum contaminant level goals (MCLGs) and maximum contaminant levels (MCLs) for a number of contaminants. In 1986 and 1996, the SDWA was amended, resulting in a substantial increase in the number of regulated compounds. Water utilities were also required to monitor for a large number of unregulated compounds for which MCLs had not been developed. Currently there are National Primary Drinking Water Regulations (NPDWRs) for 84 contaminants. These standards were adopted by DOH, are as set forth in the Drinking Water Regulations WAC 246- 290, and are put forth in Table 8-1 . The SDWA also required EPA to set non -enforceable secondary drinking water standards for contaminants that adversely impact the aesthetic water quality. These standards are not enforced and are referred to as secondary MCLs.

The data shows that the City has high quality water from the well sources and in the distribution system. The regulations discussed in this section include: • Total Coliform Rule (TCR) • Fluoride Regulation • Lead and Copper Rule (LCR) • Phase I - Volatile Organic Compounds (VOCs) • Phases II and V - Synthetic Organic Compounds (SOCs) & Inorganic Compounds (IOCs) • Iron and Manganese • Wellhead Protection • Stage 1 Disinfectants/Disinfection Byproducts Rule • Radionuclides Rule Water Quality Page 8-2 E City of Port Orchard 2009 Water System Plan • Arsenic Rule • Consumer Confidence Reports Rule (CCRs) • State Regulated Contaminants 8.3.1 Total Coliform Rule The TCR requires utilities to develop a coliform monitoring plan. The City is currently required to collect a minimum of 10 routine coliform samples every month. Based on current regulations, the City will be required to increase its number of monthly routine samples when it serves over 8500 people. If one or more coliform bacteria are detected in a sample (positive sample), the City is required to collect and analyze three repeat samples for each positive sample. One repeat sample must be taken from the same location as the original positive sample. A repeat sample must be collected within five service connections of each side of the original positive sample location. All routine and repeat samples that are positive for coliform must be analyzed for fecal coliform or Escherichia coli (E. coli.). Fecal coliform or E. coli are indicators of potential recent sewage or animal waste contamination of the water and are cause for increased public health concern. The most recent update to the City's Coliform Monitoring Plan is included in the Appendix. . The City collects nine samples in the City's system and two samples in McCormick Woods per month. The sample locations are divided among the City's wells, storage tanks, and set sample stations in the distribution system. Samples are analyzed by a Ecology -certified laboratory as required. The McCormick Woods system had 0 of 60 (0%) samples showing positive for Coliform for the years 2003 and 2004. The City's system had 1 of 96 (1%) positive in 2003 and 4 out of 96 (4%) positive in 2004. The goal is 0% samples with total coliform per month, and the MCL is greater than 5% samples with total coliform per month. The City tests positive total coliform samples for E. coli. As the City's customer base continues to grow, the sampling requirements will increase. No action besides continued monitoring are required at this time. 8.3.2 Fluoride Regulation An MCL of 4.0 mg/L for fluoride concentration in drinking water was promulgated by EPA in 1985. The purpose of the fluoride MCL is to reduce the public health risk of contracting skeletal or dental fluorosis (mottled tooth enamel) due to excessive fluoride concentrations in drinking water. Water quality must be monitored for fluoride annually for surface water supplies and every third year for groundwater supplies. There is a 2.0 mg/L secondary MCL for fluoride. A Water Quality (PACE) Page 8-3 City of Port Orchard 2009 Water System Plan The City triennially collects samples for fluoride analysis from its well sources. Data reports were reviewed for samples collected in 1993 and 2002. For these samples reported concentrations in treated water varied from 0.5 to 0.9 mg/I and untreated concentrations were less than 0.2 mg/L for all well sources. The CCR's for 2003 and 2004 show Fluoride concentrations varying between less than 0.2 mg/L and 1.0 mg/L. The City's water is fluoridated to 1.0 mg/L. Because the City's source concentrations of fluoride are well below the MCL, fluoride is added. However, the City receives unfluoridated water from the City of Bremerton. The quantity of unfluoridated water the City receives will vary. It is anticipated that fluoride concentrations will vary throughout the City when City of Bremerton water is used. 8.3.3 Lead and Copper Rule EPA adopted the Lead and Copper Rule for drinking water in 1992. Lead or copper in tap water is predominantly related to corrosion of plumbing system components, including copper pipes, lead -based solder used to join segments of copper pipe, and brass faucets that contain lead and copper. The rule requires samples be collected from targeted high risk sites. The Lead Action Level is exceeded if more than 10 percent of the samples collected from the targeted sites exceed 15 micrograms per liter (µg/L) in a 6-month monitoring period. The Copper Action Level is exceeded if more than 10 percent of the samples exceed 1.3 mg/L in a 6-month monitoring period. If the monitoring results for a public water system (PWS) exceed the Lead Action Level, the water system must conduct a public information campaign and if either the Lead or Copper Action Level is exceeded, the utility must implement and optimize corrosion control strategies. The City conducts regular sampling in the distribution system. Sampling performed in 2003 showed no levels above the action level for either Lead or Copper. The Copper concentrations varied from 0.2 to 0.4 mg/I and the Lead concentrations varied from 2 to 7 pg/L, all well below the action level. The City is not required to take Lead and Copper samples in 2005. The City has low lead and copper concentrations in the samples. No impacts are anticipated. 8.3.4 Phase I —Volatile Organic Compounds In 1987, EPA promulgated MCLs for eight Phase I VOCs as shown in Table 8-1. In addition, monitoring was required for an additional 51 unregulated organic compounds. Groundwater systems were required to sample each entry point into the distribution system. State regulatory agencies with primacy were allowed to reduce the sampling Water Quality Page 8.4 City of Port Orchard 2009 Water System Plan frequency for groundwater systems if VOCs were not detected and the system is considered not vulnerable. If no VOCs were verified during the initial 12-month monitoring period, the utility is required to monitor every 36 months. The City collects samples for VOC monitoring every 3 years for every well except weR Well 8, which is sampled every three months. City reports were reviewed for samples collected in 2000. The results are shown in Table 8-3 below. Confirm whether there is any other data. Table 8.2 Volatile Organic Compounds (VOC) EPA Regulated CompoundZN Sample Results µg/L 134 Bay 980 Mitchell Chloroform 1.0 1.1 Bromodichloromethane 0.3 0.5 Chlorodibromomethane 0.2 0.4 Bromoform ND 0.2 Total Trihalomethane 1.5 2.2 Because chloroform is regulated as a THM and the MCL for TTHM is 100 Ng/L, the amount of chloroform detected in the samples was not a concern. Based on historical data, the City groundwater complies with the established MCLs. No impacts are anticipated other than the continued cost of monitoring. 8.3.5 Phases II and V — SOCs and IOCs On January 1, 1993, EPA established regulations for 38 Phase II and 23 Phase V Synthetic Organic Compounds (SOCs) and Inorganic Compounds (IOCs). The contaminants regulated under Phase II and Phase V are listed in Table 8-1. A 9-year compliance cycle containing three 3-year compliance periods was established in 1993. Systems must complete base monitoring and increase monitoring based on trigger levels. Monitoring requirements for asbestos, nitrate, and nitrite are distinct from the standardized monitoring framework set up for the other SOC/VOCs. Asbestos monitoring is conducted every 9 years unless the MCL is exceeded; then quarterly monitoring is required. Nitrate monitoring requires an initial round of quarterly samples followed by annual monitoring. If the nitrate results exceed 50 percent of the MCL, the system is required to continue taking quarterly samples. Nitrite monitoring requires an initial sample and then, if the initial sample exceeds 50 percent of the MCL, � Water Quality (PACE) Page 8.5 City of Port Orchard 2009 Water System Plan may require quarterly monitoring. No waivers are given for nitrate and nitrite monitoring due to the acute danger of methemoglobinemia. The City monitors each well every 3 years for IOCs. Table 8-3 summarizes the sample concentrations collected by the City for Phase II IOCs. None of the samples collected at the wellheads had any inorganic contaminant concentrations that exceeded an established MCL. Table 8-3 Inorganic Contaminant Monitoring Results 2000-2004 Inorganic Contaminant Concentration Range Measured for All Active Wellheads (m /L) Established MCL(b) (m /L) Asbestos State waiver through December2010 7 mf/L(a) Antimony less than 0.005 0.006 Barium less than 0.10 2 Beryllium less than 0.003 0.004 Cadmium less than 0.001 0.005 Chromium less than 0.01 0.1 Cyanide less than 0.05 0.2 Mercury less than 0.0005 0.002 Nickel less than 0.04 N/A Nitrate (as N) less than 0.1 to 0.3 10 Nitrite (as N) less than 0.01 1 Selenium less than 0.005 0.05 Thallium less than 0.002 0.002 Note: (a) MF/L - million fibers per liter greater then 10 microns in length. (b) From Table a-1. Nitrate and nitrite are of interest because their presence is indicative of heavy fertilizer use or water contaminated with sewage. The nitrate concentrations as tested in 2001 for Wells 5, 6, 7, and McCormick Woods were less than 0.1 mg/L with a value of 0.3 mg/L for Well 8. The nitrate concentrations as tested in 2005 were less than 0.5 mg/L for Wells 4, 6, 7, and 8, well below the MCL of 10 mg/L. The City samples for Nitrate yearly at each source. For Phase II and Phase V SOC monitoring, the City samples two samples each three years at each well except Well 9 which is sampled once per quarter. Organic Waivers are currently granted for Dioxin, Glyphosphate, Diquat and Endothall for all sources; for EDB and other soil fumigants for Wells 4, 6, 7, 8 and 9 through December 2007. All sample concentrations tested have been below applicable MCLs. No treatment impacts on the City are expected due to these regulations. Water Quality Page 8•6 City of Port Orchard 2009 Water Svstem Plan 8.3.6 Iron and Manganese EPA established secondary MCLs for iron and manganese based on aesthetic considerations. The MCLs for iron and manganese are 0.3 mg/L and 0.05 mg/L, respectively. Table 8-4 Untreated Iron and Manganese Concentrations (2002) Well Number Iron, mg/L (MCL = 0.3 MG/L) Manganese mg/L (MCL = 0.05 MG/L) 4, 5, 7 Less than 0.1 0.04 6 Less than 0.1 0.04 S Less than 0.1 Less than 0.01 Neither iron nor manganese is considered toxic at the concentrations found in the City's water supply. EPA has listed manganese on the Drinking Water Contaminant Candidate List to be used in selecting contaminants for regulation. Manganese is identified as a high priority for EPA to determine whether it should be regulated. It is anticipated that if manganese is regulated as a primary contaminant, the MCL will be much higher than the current secondary MCL. No treatment impacts on the City are expected due to this regulation. 8.3.7 Wellhead Protection Federal and State laws require the City to implement a wellhead protection program. The first phase of implementation was to define protection areas for each wellhead. These areas were delineated in the Port Orchard Wellhead Protection Area Investigation (AGI Technologies 1997). The Wellhead Protection Plan will be updated as part of bringing any new wells online. 8.3.8 Stage 1 Disinfectants/Disinfection Byproducts Rule The Stage 1 D/DBP Rule regulates the concentration of disinfectants such as chlorine, chlorine dioxide and chloramines, which are oxidants used to control waterborne disease. The D/DBP Rule also regulates DBPs such as THMs, haloacetic acids (HAAs), bromate, and chlorite. DBPs are formed when disinfectants used to control microorganisms react with natural organic matter (NOM) in water. Water Quality Page 8.7 City of Port Orchard 2009 Water Svstem Plan Table 8-5 Stage I Disinfection Byproducts Rule Compound MCL MDRL THM 80 µg/L HAA5 60 µg/L Bromatei°i 10 µg/L Chloriteibi 1 mg/L Chlorine Dioxide() 0.8 mg/L Chlorine") 4 mg/L Chloramines") 4 mg/L Notes: Required only for systems using ozone. Required only for systems using chlorine dioxide. Required only for systems using the identified disinfectant. The City disinfects drinking water with sodium hypochlorite at each well site, with Wells 4, 5, and 7 receiving combined treatment. Each well treatment site may be considered a "Water Treatment Plant" under the D/DBP Rule. The City is required to collect one set of TTHM and HAA samples at each treatment plant per year. When water is supplied through one of the Bremerton water system connections for more than 15 days in any given calendar quarter, the City is required to collect one set of TTHM and HAA samples for that quarter. It is unlikely that the City would develop a DBP problem from the water produced by City wells. 8.3.9 Radionuclides Rule Radionuclides can naturally occur in water supplies. EPA has revised the current radionuclides regulation, which has been in effect since 1977, by requiring new monitoring provisions that will ensure that all customers of community water systems will receive water that meets the MCLs for radionuclides in drinking water. EPA also has promulgated a standard for uranium as required by the 1986 amendments to the SDWA. The current standards are: combined radium 226/228 of 5 pCi/L; a gross alpha standard for all alpha emitters of 15 pCi/L, not including radon and uranium; a combined standard of 4 mrem/year for beta emitters. The new MCL for uranium is 30 jig/L. This final rule will provide improved health protection through monitoring improvements for the combined radium-226/228 standard (a carcinogen) and for uranium (a kidney toxin and carcinogen) in drinking water. The rule became effective on December 8, 2003. New monitoring requirements will be phased -in between that date and the beginning of the next Standardized Monitoring Framework period, December 31, 2007. Water systems will determine initial compliance under the new monitoring requirements using the average of four quarterly samples or, at state discretion, using appropriate grandfathered data. The City currently samples for Water Quality E Page a-s `ll City of Port Orchard 2009 Water System Plan Radium 228 at each well two samples every three years. 2005 sampling data shows no detectable Radium 228 in Wells 4, 6, 7, 8, and 9. There are no anticipated treatment impacts to the City. 8.3.10 Arsenic Rule Arsenic is a naturally occurring element found in water supplies. EPA promulgated a rule controlling arsenic concentrations in drinking water in January 2001. Increased skin cancer occurrence and possibly increased internal cancer are health risks associated with elevated arsenic concentrations in drinking water. The previous MCL of 50 µg/L will be lowered to 10 µg/L effective January 2006. The City has sampling data from 2002-2004 for all wells. The values are from less than 0.002 to 0.002 mg/L. With the MCL set at 10 µg/L, no treatment impacts are anticipated. 8.3.11 Consumer Confidence Reports Rule EPA issued the CCR Rule 19 August 1998. The CCR Rule establishes requirements for water systems to provide annual reports to all customers. The first CCR was required to be issued to customers by 18 October 1999. The City has prepared and distributed CCRs for the years 2003 and 2004. The CCRs for these years are included in Appendices. 8.3.12 State Regulated Contaminants The State Department of Health regulates the following additional contaminants and qualities that are not currently regulated by the EPA. Sodium, Hardness, Conductivity, Turbidity and color have "State Reporting Levels" that are shown in Table 8-6 along with the City's testing data from 2002. Table 8-6 State Regulated Contaminants Contaminant Concentration Range Measured for All Active Wellheads (m /L) Established State Reporting Level MCL Sodium 3.37 to 6.53 5 mg/L Hardness 44 to 68 10 mg/L Conductivity 86 to 131 10 US/cm 700 uS/cm Turbidity less than 0.05 to 0.35 0.1 NTU 1 NTU Color less than 5 5 color units 15 color units I Water Quality (PACE) Page 9.9 City of Port Orchard 2009 Water System Plan 8.3.13 Cross Connection Control The City's Cross Connection Control Program (CCCP) is established by Port Orchard Municipal Code 13.04.100, a copy of which is included in the Appendices to this Plan. The cross connection control program is in compliance with WAC 246-290-490 and addresses the nine key elements required for Cross Connection Control. Please refer to Section 9.7 for additional information. 8.4 ANTICIPATED REGULATIONS This section discusses regulations that are expected to be issued by EPA that may impact the City. The regulations discussed in this section include: • Stage 2 Disinfection Byproduct Rule • Ground Water Rule (GWR) (formerly Groundwater Disinfection Rule) • Radon Rule 8.4.1 Stage 2 Disinfection By-product Rule The Stage 2 Disinfectant and Disinfection Byproducts Rules (DBPR) is one part of the Stage 2 Microbial and Disinfection Byproducts Rules (M-DBP) which are the final phase in the M-DBP rulemaking strategy affirmed by Congress as part of the 1996 Amendments to the Safe Drinking Water Act (SDWA) The Stage 2 DBPR focuses on public health protection by limiting exposure to DBPs, specifically total trihalomethanes (TTHM) and five haloacetic acids (HAA5) which can form in water through disinfectants used to control microbial pathogens. The Stage 2 DBPR will apply to all systems that add a disinfectant other than ultraviolet light. Under the Stage 2 DBPR systems will conduct an evaluation of their distribution system to identify the locations with high disinfection byproduct concentration. These locations will then be used by the systems as the sampling sites for DBP compliance monitoring. Under the Stage 2 DBPR compliance wit the maximum contaminant levels for TTHM and HAA5 will be calculated for each monitoring location in the distribution system. This approach, referred to as the locational running annual average (LRAA) differs from current requirements which determine compliance by calculating the running annual average of samples from all monitoring locations across the system. The Stage 2 DBPR will also require systems to determine if they are experiencing short term peaks in DBP levels referred to as "significant excursions". Systems experiencing significant excursions would be required to review their operation practices and work with the State to determine actions that may be taken to prevent future excursions. Water Quality Page 8.10 City of Port Orchard 2009 Water System Plan The proposed Stage 2 DBPR was published August 2003. A public meeting was held December 2004. The final rule has not yet been published. The City will be required to modify the existing DBP Monitoring Plan to reflect the Stage 2 DBPR requirements. An Initial Distribution System Evaluation (IDSE) will need to be conducted to identify the locations with high disinfection byproduct concentrations. These locations will then be used for DBP sampling locations. The sampling results will then be analyzed with a locational running annual average (LRAA) rather than then running annual average (RAN now used. The City will also need to determine if any "significant excursions" are being experienced, and if so review their operational practices to prevent further excursions. 8.4.2 Groundwater Rule The 1996 SDWA Amendments require EPA to promulgate NPDWRs requiring disinfection as a treatment technique for all PWSs, including groundwater systems as necessary. A proposed Ground Water Rule (GWR) was issued in May 2000. The Proposed Rule develops a multiple barrier approach for the GWR, including the following: • System sanitary surveys conducted by the State and identification of significant deficiencies; • Hydrogeologic sensitivity assessments for undisinfected systems; • Source water microbial monitoring by systems that do not disinfect and draw from hydrogeologically sensitive aquifers or have detected fecal indicators within the system's distribution system; • Corrective action by any system with significant deficiencies or positive microbial samples indicating fecal contamination; and • Compliance monitoring for systems which disinfect to ensure that they reliably achieve 4-log (99.99 percent) inactivation or removal of viruses. EPA proposed the Groundwater Rule in May of 2000. As of August 2005, EPA is still having discussions about the GWR and has not yet formally resubmitted its final rule for review. It will most likely be finalized early next year, after the Stage 2 DBP rules are promulgated. The City is disinfecting its groundwater supplies. Impacts of groundwater disinfection include: • Potential for increased DBP formation • Increased corrosiveness of the water • Capital and O&M costs for disinfection facilities. Water Quality PACE Page 8.11 City of Port Orchard 2009 Water System Plan 8.4.3 Proposed Radon Rule Of all the contaminants addressed by the Radionuclides Rule, Radon-222 has been the most scrutinized and of greatest concern to water utilities. Radon-222 is an inert, noble gas formed from the radioactive decay of Radium-226, as part of the Uranium-238 decay series. Radon is produced in the rock and soil matrix and readily migrates to groundwater where it dissolves. The 1996 SDWA Amendments directed EPA to withdraw the proposed 300 picocuries per liter (pCi/L) MCL for radon and have the National Academy of Sciences (NAS) conduct a risk assessment for radon in drinking water using the best available science. NAS also investigated the health risk reduction and cost analysis for various radon MCLs under consideration. EPA issued a Proposed Radon in Drinking Water rule in November 1999. The proposed radon MCL is 300 pCi/L. The proposed alternative radon MCL is 4,000 pCi/L. If the equivalent drinking water level is greater than the proposed MCL, then EPA has established guidelines for a multi -media radon mitigation program to reduce indoor air radon concentrations. Either the state or the utility must develop and obtain approval of a multi -media radon mitigation program to qualify for the alternative MCL. Utilities using the alternative MCL may be required to state in their CCR that they meet the alternative MCL but not the MCL. If radon removal is necessary, the most likely treatment option is aeration. Liquid -phase granular activated carbon (GAC) is another option; however, GAC is much more expensive, and the spent carbon may be considered a hazardous waste. If aeration is selected, radon air emissions may have to be addressed. However, the additional risk from emitting radon from aeration relative to the risk posed by background radon levels in outdoor air is not significant. 8.5 CITY OF BREMERTON SUPPLY The City of Bremerton's water supply is primarily from a surface water source treated with chlorination and pH adjustment. The City's well water is disinfected and fluoridated. On the occasions when the City of Bremerton's water supply is used, the level of fluoride in the water will be decreased in the areas served by the mixed supply. If this is a rare event, no significant impact should be felt. If this happens regularly, the benefits from fluoridation would be reduced for the areas receiving mixed water supply. 8.6 TREATMENT IM The City has implemented groundwater disinfection and fluoridation at each well. Potential treatment improvements include installation of rechlorination facilities to ensure that chlorine Water Quality Page 8.12 City of Port Orchard 2009 Water System Plan residuals are maintained throughout the system and consideration of aeration facilities to control taste and odor issues stemming from elevated levels of hydrogen sulfide in Wells 4 and 5. Determination of the need for increased aeration will be dependent on the success of the Well 10 drilling effort that is currently underway. If yields are sufficient, this well may reduce dependency on Wells 4 and 5 and eliminate the need for taste and odor control. However, the quality of water received from the new well is expected to require some level of treatment. Additional studies regarding treatment at the new facility and its impact on other existing well will be required before source development is complete. Water /// Pagea 8.13 8-13 SECTION 9 OPERATIONS PROGRAM 9.1 INTRODUCTION Operations and Maintenance plays a crucial role in a utility's capacity to provide a safe and reliable source of potable water. An aggressive preventive maintenance program will prolong the life of a water system along with increasing a system's reliability. The climate in which water utilities now operate is fundamentally different than that of 20 or even 10 years ago. A growing regulatory burden, increasing operations costs and aging infrastructure now demand that water utilities have in place an organized, efficient and aggressive operations and maintenance program. This Section outlines the overall operation of the City of Port Orchard's water system and provides a summary of day-to-day operations, routine maintenance of the system, and emergency operating procedures. Detailed information related to specific facilities such as operations manuals are not included herein but considered an integral part of overall system operation and maintenance. Similarly, the City has prepared a vulnerability assessment of its water system and maintains a City-wide Emergency Response Plan that incorporates water system emergency response. 9.2 GENERAL INFORMATION Primary Contact: Mark Dorsey, P.E., Public Works Director/City Engineer 216 Prospect Street Port Orchard, WA 98366 Telephone: 360.876.4991 FAX: 360.876.4980 Emergency 24 Hour: City Operations/Shop: Jay Cookson 1535 Vivian Court Port Orchard, WA 98367 Phone: (360) 876-2722 FAX: (360) 876-4607 Emergency: 9-1-1 State Dept of Health Identification Number: 68900 Environmental Protection Agency System ID: WA5368900 9.3 RESPONSIBILITY AND AUTHORITY The City of Port Orchard water system is one component of the City's Public Works Department and under the direct supervision of the Public Works Director/City Engineer. Among the responsibilities of this position is preparation of the annual budget, preparation of the capital PACE operations Program Page 9-1 City of Port Orchard 2009 Water System Plan improvement plan for Public Works and implementation of the approved improvements. In addition to reporting to and implementing direction from the mayor and seven member City Council, the Public Works Director oversees in-house field operations of the water system. Day - today management of field operations and maintenance of the system is the responsibility of the Public Works Foreman. A field staff of 11 employees carries out water system operations, maintenance and emergency response. 9.4 PERSONNEL CERTIFICATION Under regulations established by the Washington Department of Health (DOH), the City is required to maintain the services of a State Certified Water Distribution Manager 1 (WDM-1). A listing of current water system operations related certifications held by City staff is provided in Table 9-1. Table 9-1 Water System Certification Operator Certification(s) Jay Cookson Water Manager II Ray PettyWater Manager ll, Dan Castillo Water Manager II George Thompson Water Manager ll, Cross Connection Control Specialist Von Nix Water Manager ll, Cross Connection Control Specialist Marc Fournier Cross Connection Control Specialist Dave Boltz Cross Connection Control Specialist Jill Satran-Loutin Water Distribution Specialist Alan Rckett Water Distribution Specialist Bill Thiele Water Distribution Specialist Linda Rosa Water Distribution Specialist The City of Port Orchard encourages state certifications of water system personnel and sponsors attendance at appropriate safety and technical seminars. 9.5 ROUTINE OPERATIONS The City of Port Orchard maintains a detailed routine operation and maintenance program in order to insure proper operation of all mechanical facilities and maximize the efficiency and life of the system. Routine operations includes making daily rounds to visually check system facilities and reservoir reading devices on a regular basis, monitoring flow, service and main line repairs, meter repairs and calibration and responding to customer inquiries, as necessary. Additionally, preventative maintenance, such as regularly servicing pumps and motors, exercising valves and hydrants, cleaning and painting reservoirs, and flushing pipelines, is required to ensure adequate overall operation and maintenance of the system. The following sections generally outline the routine operations and maintenance practices and schedule for primary system components. Operations Program ((( �����assa—.�s��A� Page 9-2 6�C City of Port Orchard 2008 Water System Plan In addition to the routine operation and maintenance, the City repairs service lines, mains, meters and fire hydrants as needed. The City has a program for replacing all meters in the system with touch -read devices over time. The City anticipates a telemetry upgrade in 2006 that will allow for enhanced continuous electronic monitoring to ensure proper operation, accuracy and intrusion. 9.5.1 Supply Wells The supply wells are visited daily to check security, monitor source quality and quantity, and verify site conditions. In addition daily monitoring of water quality as described in later in this Section is accomplished. The City has an approved Wellhead Protection Plan to ensure on -going protection of the groundwater supply. 9.5.2 Storage Reservoirs Storage reservoirs are visited daily to verify security and check overall site conditions. Reservoirs are drained and cleaned, or otherwise inspected periodically and at least every five years. Inspection of the integrity of reservoir coatings is accomplished as part of the reservoir cleaning process and reservoirs are spot painted as required to prevent rusting or degradation of coating systems. Complete recoating of reservoirs is scheduled based on the results of these periodic cleanings and inspections. 9.5.3 Pump Stations Pump Stations are checked daily to verify site conditions and security and the proper operation of all equipment. Pump data is recorded by the operational telemetry system and monitored to identify any irregularities in the system. Pumps are serviced regularly as determined by hours of service. 9.5.4 Valves and Hydrants Port Orchard has a valve maintenance schedule which includes annual exercising of all valves in the system. Hydrants are exercised biannually and tested as appropriate. Pressure regulating valves are inspected monthly and calibrated as required. 9.5.5 Distribution System The City maintains an annual leak detection program whereby outside leak detection specialists are utilized to identify leaks within the distribution system. All leaks identified are repaired. In addition, City staff respond to reported leaks and water quality issues immediately. Dead-end mains are flushed at least annually to provide necessary cleaning of these potential water quality problem areas. Additionally, water mains are flushed as necessitated by customer complaints or pipeline repairs or other operations that may result in water quality degradation. The City maintains a record of all flushing operations to assist with determination of non -revenue water and long range conservation monitoring. Operations Program Page 9.3 City of Port Orchard 2009 Water System Plan 9.5.6 Inspection Water system personnel also assist with new construction inspection, especially for developer extension projects. Additional assistance can be obtained by direct contract with contractors listed on the City's small works roster of approved contractors. This resource is utilized when City personnel are not available, not qualified for the type of construction being accomplished or when the project costs exceed the statutory limits.4 9.6 WATER QUALITY MONITORING The City of Port Orchard's water quality monitoring program and results of recent testing are detailed in Section 8 of this Plan. The City's Cross Connection Control Program and Coliform Monitoring Programs are included in the Appendices. Copies of most recent water quality tests and Port Orchards Consumer Confidence Reports are also included. As noted in Section 8, the City is currently working on compliance with Stage 2 Disinfection By Products (DBP) Monitoring. Recognizing that the State of Washington Department of Health has recently assumed primacy for DBP monitoring, any program additions, changes or modifications will be submitted to the appropriate DOH representatives. 9.7 CROSS CONNECTION CONTROL The City's Cross Connection Control Program (CCCP) is established by Port Orchard Municipal Code 13.04.100, a copy of which is included in the Appendices to this Plan. The cross connection control program is in compliance with WAC 246-290-490 and addresses the following nine key elements required for Cross Connection Control: Element 1: Establish Legal Authority Port Orchard City Code 13.04.100 establishes legal authority to implement a cross connection control program and references Ordinances relevant to the implementation of the Cross Connection Control Program. Element 2: Procedures/Schedules for Hazard Evaluations The City evaluates new and existing service connections to make sure the connection does not pose a danger to the distribution system. Premise isolation with a Reduced - Pressure Backflow Assembly (RPBA) are required on all commercial connections. Element 3: Procedures/Schedules to Eliminate/Control Cross Connections The City requires installation of approved RPBA's to protect the public water supply. At a minimum, annual testing of the backflow devices at the owner's expense is required. Port Orchard is currently developing a customer education program for property owners using Operations Program Page 9-4 City of Port Orchard 2008 Water System Plan irrigation systems for additional control and protection of groundwater sources. This is expected to include special mailings to customers in areas of the system where irrigation systems are commonplace (i.e. McCormick Woods). Element 4: Provide Qualified Personnel The City of Port Orchard maintains fulltime certified Cross Connection Specialists, as indicated in Table 9-1. Element 5: Procedures/Schedules for Backflow Preventer Inspection and Testing At a minimum, the City requires annual testing of the backflow devices at the owner's expense. Element 6: Assembly Testing Quality Assurance/Quality Control (QA/QC) The City ensures that results from backflow prevention assembly inspections and tests are documented and reported in an acceptable manner. The City also monitors tester certifications and test kit calibrations and requires test reports to be filled out completely and to be submitted in a timely manner. Element 7: Backf low Incident Response Plan The City follows procedures identified in WAC 246-290-490 for responding to a backflow incident and implementing enforcement. Element 8: Public Education Port Orchard provides cross connection educational material for customers that include pamphlets, periodic bill inserts, and as noted under Element 3 above, special mailings for public education regarding irrigation systems. Educational materials used in the past or currently under consideration include reports on the cross connection control program, its purpose and rationale. This information may also be included in Consumer Confidence Reports. Element 9: Establish/Maintain Cross -Connection Control Records The City's Cross Control Specialists (CCS) have developed and maintained cross connection control records in WAC 246-290-490(3)(j) and (8). A data base is maintained track all relevant information including master list of service connections, inventory information, backflow incidents and annual summary reports. Element 10: Meet Additional Reclaimed Water Requirements The City of Port Orchard is working with Karcher Sewer District to develop reclaimed water use opportunities within the system. Evaluation of any potential opportunities will include consideration of cross connection control in accordance with all applicable rules, regulations and standards. Property owners will have ultimate responsibility for cross Fes\ Operations Program FIACE/\ Page 9-5 City of Port Orchard 2009 Water System Plan connection associated with reclaimed water use and the City may require a more frequent schedule of device inspection and control, depending on the specific application of reclaimed water. 9.8 EMERGENCY PLAN The City of Port Orchard has performed a vulnerability assessment of its system in accordance with Environmental Protection Agency requirements and maintains a City-wide response program that includes water system operation under emergency conditions. As stated previously, all key pumping supply facilities are equipped with either permanent on -site power or provisions for connecting an emergency power generator. An adequate supply of parts, disinfectant and maintenance equipment is kept on -hand to respond to routine emergencies or system failures. All storage reservoirs are equipped with shut-off valves in the event of contamination and the City is currently working on upgrade of the telemetry monitoring system to increase its ability to detect and respond to emergency conditions. The City enjoys good working relationship and informal mutual aid agreements with neighboring water purveyors and agencies. This arrangement is very beneficial for local emergency conditions but does not provide the security of back-up assistance in more widespread emergency conditions that would limit resources. A small works roster of contractors available to assist under emergency conditions is maintained and updated regularly. The City is also a member of the "One Call System" for which the City has a 24 hour to and from response time. This system, which was established by the major utilities providers in the Puget Sound region, provides coordination and assistance for preventing damage to existing facilities during maintenance work or new construction. 9.9 WATER SHORTAGE RESPONSE Redundancy in water supply wells in the Port Orchard water system and interties with the City of Bremerton and Annapolis Water District provide a great deal of protection against an emergency related water shortage. In the event of a drought related water shortage, the City will work with neighboring purveyors to develop a consistent drought awareness program and recommendations for reducing water demands. In addition, the City would work with high water users (government facilities, irrigation accounts, etc.) to request curtailment in water use until water supplies can be reestablished. Operations Program Page 9.6 SECTION 10 FINANCING & IMPLEMETATION 10.1 GENERAL The purpose of this section is to present a strategy for implementation of the recommendations and findings previously discussed in this Comprehensive Plan and, together with the proposed improvements identified in previous sections, and outline a definitive program for future development of the City of Port Orchard's water system. The City's general plan for implementation of this Plan is outlined in subsequent discussions of the following: financial considerations, funding sources, current rates and charges, methods of financing capital improvements. More detailed financial analyses and strategies are expected with ongoing yearly reviews and updates of rates and charges. Funding options for new development within the service area is discussed and generally considered the responsibility of the developer. 10.2 FINANCIAL CONSIDERATIONS Financial review and recommendations are made based on estimated future expenses, operating experience and plans for future projects. The major considerations in estimating expenses include the following: • Administration, operation, maintenance and the day-to-day expenses of operating and maintaining the water and sewer systems; • The charges associated with water production and purchases; • Financing capital improvements which are necessary to provide adequate service and extension to existing and new service areas; • Replacement and updating of existing facilities that require renewal because they are obsolete or no longer serviceable; and, • Debt service requirements to provide for repayment of interest and principal for all outstanding bonds for previous system improvements. 10.3 WATER SYSTEM BUDGET The financial policies and financial status of the of the City's water utility have been reviewed to evaluate the ability to provide the level of service and recommended improvements outlined in this document. In developing the anticipated six -year budget for the water utility, data from the 2007 water rates study was used and updated based on the recommendations contained in this plan. It was noted that past budgeting has been accomplished for the water and sewer utilities together. The budget presented in Table 10-1 separates the two utilities using assumptions of allocation of certain expenses (such as labor costs and overall public works equipment that is utilized for administration, operation and maintenance of the utility). It is recommended that the City Financing and Implementation PA E Page 10.1 City of Port Orchard 2009 Water System I continue to refine the splitting of costs between the utilities to ensure that adequate revenues are generated for the utilities independently and to ensure that one utility is not subsidizing the other. This will become increasingly important as outside funding sources are sought for system upgrades and improvements. Table 10 -1 was prepared to project Water Department financial performance which includes revenue from new services and customer revenue from the sales of water. Line item system operating expenses have been estimated for the years 2009 through 2013. Where additional staff are anticipated to meeting the growth of the water utility, new staff have been added. Capital expenses have also been estimated and projected for this time period. Funding for the CIP included in this plan is shown in the line item describe as "Funding Capital Improvement Program". $8 million dollars is show in the 5 year period from 2009 to 2013 for funding needed Capital Improvements. This corresponds roughly with the funding needs included in this plan. Key to this projection is the continued growth of the water utility. The table includes 310 new ERU's per year for this 6 year period. The Table also assumes a loan or bond funding to help fund the CIP program of $5 million. A repayment interest of 4.5% is assumed in the projections. If a low interest loan or grant was secured for some or all of the water improvement needs there would be money available to make additional system upgrades. It is important to note that the anticipated budget is presented as a starting point for more detailed financial analyses and determination of the need for outside funding assistance. A key recommendation of this Plan is for the City to continue to monitor yearly revenue and expense requirements to insure a sound financial utility continues.

In this table $5 million in financing is assumed. Additionally rates need to keep up with the cost to operate and maintain the system and provide for depreciation of the system. The newly adopted rates cover a portion of the water system depreciation but do not intended to fully fund depreciation. A depreciation fund is not shown on this table because of the need to fund the CIP and system replacement program. The following listed revenue sources are either currently utilized by the City or are potentially available for funding operation and maintenance expenses and financing capital improvements to the water systems. Careful review of each potential source of funding (primarily grants and low interest loans) is recommended to develop the most cost effective financial strategy for future system operation. In addition, regular consideration of evaluation of connection charges and rates as discussed below is recommended as a follow-up to this Plan. 10.4.1 Rates Rates and charges are utilized to finance expenses which were not paid either when the system (or portion thereof) was initially constructed, or by the assessment of general facility charges. These expenses typically include: operation and maintenance expenses; water production and purchase costs; customer accounting and collection expenses; administration and general expenses; taxes; debt service requirements; and renewal and replacement or capital expenses. The City's current water rates are shown in Table 10-2. The rates are established by Ordinance No. 013-08 effective July 1, 2008, and remain in effect at the publishing of this Plan. Financing and Implementation Page 10.4 DA Ac City of Port orchard 2008 Water System Plan Table 10.2 Existing Water Rates (As of J ly 1, 2008) Size of Service BI-MonthlyRate 3/4 Inch $22.50 1 Inch $23.50 1 1/2 inch $26.50 2 inch $29.50 3 inch $35.50 4 inch $47.50 6 inch $68.50 8 inch $89.50 10 inch $113.50 Consumption Charge 0 - 3,000 gallons $18.50 3,000-5000 gallons $22.50 5,001-50,000 gallons $2.10 per 1,000 gallons 50,001 - 100,000 gallons $2.20 per 1.000 gallons 100,001-150,000 gallons $2.30 per 1,000 gallons 150,001 plus gallons $2.40 per 1,000 gallons Capital Facility Charge $4500/Equivalent Residential Unit (3/4" meter) It is recommended the City review the then current rates and charges on a yearly basis. Consideration of elimination of the water allocation included in the base rate would provide the City with more readily available data for water consumption analyses and evaluation of conservation programs. In addition, it is recommended that the City review and consider a more stringent tiered or block rate structure where base water consumption is charged at a lesser rate than higher volumes of use. This type of rate structure has been very effective in encouraging conservation in general, although no amount of water included in the base water rate and a larger differential between rate would typically be more effective. This provides customers a way to save on their water bills through conservation and mandates that the high water users pay a fair share of system facilities and operation costs determined by volume. Another rate structure that may be appropriate and warrants consideration is a simple differential rate between winter and summer water use to encourage conservation during the typically high demand summer months. 10.4.2 Connection Charges New connections to the City of Port Orchard are required to pay connection charges in addition to the costs associated with the purchase and installation of the water meter. As shown in Table 10-2, there is currently one charge to cover the cost of Capital Facilities within the system. This Facility Charge, or CFC, is intended to provide an equitable means of for new customers of the system to pay their fair share of City-wide capital improvements. General facilities are typically identified as storage reservoirs, sources of Financing and Implementation Page 10-9 City of Port Orchard 2009 Water System Plan supply, transmission mains, pump stations and oversized pipes to serve large areas, and the facilities and equipment required to maintain the system as a whole. It is important that CFCs are maintained at a level that will support construction of new facilities and to ensure that growth pays for growth. State regulations dictate the method of calculating CFCs and provide guidance on what projects and costs can be included in the calculation. Recalculation of Capital Facilities Charges should be should be accomplished on a regular basis and is recommended as a follow-up at the close of a comprehensive water system planning effort. Local Facilities Charges, or System Development Charges as often referred to, are another type of connection charge that the City uses to insure new customers pay their equitable fair share of the existing water system. LFCs are intended to cover a connecting parties' equitable share of water system facilities in the immediate vicinity of property connecting to the system. Presently, the City requires developers to pay all costs associated with extension of service to the property being developed. When local facilities have been constructed and paid for by a previous developer, a latecomer agreement may exist requiring benefited properties which connect to a water line to pay their pro rate share of the cost to install facilities. In instances where no latecomer agreement exists, a System Development Charge is used to insure all customers pay their equitable fair share of the water system. 10.4.3 Local Improvement District (LID) Financing Local Improvement District (LID) is a means by which improvements can be financed by those property owners directly benefiting from the improvements. This method of financing is typically accomplished by the majority of benefited property owners signing a petition for the improvements. It is possible, however for a LID to be formed by City Ordinance. LID financing is generally used for local facilities improvements and initial financing is typically by bond sales or loans. The costs of improvements are typically allocated and assessed against properties within a LID area, although revenue from rates can also be used to repay the bonds required to finance a LID improvement. 10.4.4 Developer Financing New facilities constructed within the service area should be financed by the developers of presently unimproved property or property that redevelops. All of the improvements required for service to property within new plats, or commercial and industrial developments will be designed and constructed in accordance with the City's developer extension policies which are set forth in the "Developers Handbook". This document is available from the City under separate cover. Financing and Implementation Page 10-6 /\ `\/// City of Port Orchard 2008 Water System Plan 10.4.5 Combination Financing by Developers and the City It may be necessary in some cases to require the developer to construct facilities which are oversized for the current development in order to provide for the comprehensive development of the City's water system. The City in such instances may elect to enter into an agreement to reimburse the developer for the extra costs associated with increasing the size of facilities over that required to serve the property proposed for development. Oversizing should be considered when it is necessary to construct any water main 8-inches in diameter in single-family areas for Comprehensive Plan compliance. Construction of any water main in multi -family, commercial or industrial areas that is larger than the size required to serve the current development proposal is considered oversizing. 10.4.6 Bond Financing Bond financing is another methods of financing water system improvements and can be achieved by the sale of either general obligation or revenue bonds. General obligation bonds must have the support of the majority of the voters in the City and are paid through assessments against properties within the City. Revenue bonds, however, do not require voter approval and may be financed by whatever funds are available to the City for the payment of debt service. This might include revenues from water sales, general fees, latecomer charges or other funds. 10.4.7 Grant Financing Grant financing has become increasingly scarce for utility systems in recent years but is still available for some specific circumstances. Current grant programs for water system facilities include the State of Washington Centennial Clean Water Fund and State Revolving Fund for Water Pollution Control. These programs are aimed at eliminating pollution sources and/or correcting documented existing pollution problems. They are therefore not appropriate for ongoing rehabilitation and replacement projects. They may be considered, however, in the event that particular health hazards have been identified and documented and it is determined that improvements to will provide a solution to the existing pollution problems. 10.4.8 Public Works Trust Fund (PWTF) Loans Public Works Trust Fund financing is a low interest loan program which can be used to finance utility system improvements. Interest rates range from 0.5% to 2% depending on the level of local participation and the loans must be repaid within twenty years. This type of financing has been very beneficial to utility systems throughout Washington but unfortunately has been suspended during development of this Water System Plan. Those projects which may be eligible for Public Works Trust Fund financing, when it is active again, are identified in the Capital Facilities Plan. (PACE)Page and Implementation Page 10-7 City of Port Orchard 2009 Water System Plan 10.4.9 State Revolving Fund (SRF) The State Revolving Fund is a program that is similar to the PWTF program and administered by PWTF staff. Water source and treatment projects are prioritized under the competitive SRF application process. Loan interest rates are similar to PWTF rates, except that a loan fee is required in lieu of a local match. 10.4.10 Rural Development Direct Loans and Grants The Rural Development division of the United States Department of Agriculture, through Rural Utility Service, is authorized to provide financial assistance for water and waste disposal facilities in rural areas and towns of up to 10,000 people. Interest rates are set quarterly and are based on current market yields for municipal obligations. The terms on the loans can vary, with a maximum being 40 years of the useful life of the improvement or facilities to be financed, whichever is less. Rural Development Loans are federally financed, and as such, federal rules and regulations apply. It is important to note that the City of Port Orchard is approaching a population of 10,000 and eligibility for such financing will likely be restricted in the near future. Another limiting factor to obtaining grants funding from Rural Development is that water rates must be documented at a much higher level than the current Port Orchard Rates before grants become available. 10.4.11 American Recovery and Reinvestment Act (ARRA) Funding In 2009, the federal government enacted the American Recovery and Reinvestment Act (ARRA) funding as a means of creating jobs and stimulating the national economy. ARRA funding has helped finance water system improvements and other municipal infrastructure projects through grants and low interest loans. Additional funding is expected in 2010 and the City of Port Orchard may elect to pursue such funding. Careful consideration of the scope and type of projects that are most likely to be funded is required prior to investing resources into the development of funding applications. Low Impact Development (LID), source of supply and resource conservation projects in particular should be evaluated for application for funds. Monitoring the availability of ARRA funds and other unique opportunities for funding such as low rates bonds may provide unexpected opportunities for financing high priority CIP projects. 10.5 FINANCING CAPITAL IMPROVEMENTS 10.5.1 General Facilities The most difficult improvements to finance are general facilities such as reservoirs, water pump stations, transmission mains, treatment facilities and other facilities which will benefit a large area. This is because this type of facilities is generally needed before water service can be provided and often times before customers are available to assist in financing. In new and expanding areas where water or sewer service is not currently available, general facilities are typically financed by one of the following methods: Financing and Implementation Page 10-8 ACE City of Port Orchard 2008 Water System Plan • Requiring the initial developer to pay for improvements with a pay -back arrangement as the area develops (latecomer charges); • Passing a general obligation bond which is approved by voters; • Forming a LID and assessing the benefited properties equally; • City financing of improvements and assessing a General Facilities Charge (GFC) to each property within the benefited area as development occurs. These charges must be sufficient to cover all costs incurred, including interest on money and an allowance at a rate that will amortize the investment; or, • City obtained grants or low interest loans to assist in construction of these type of improvements. In established areas of the City, financing general facilities presents a different type of problem. The general facilities are normally paid for when the system is constructed and the costs are assessed against existing customers. As the system expands and new connections are added, a charge in lieu of assessment can be levied or connection charges imposed to offset the original construction costs. This money, in addition to the funds from monthly rates for renewals and replacements, should be adequate to finance general facility improvements. Theoretically, if the facilities charges are adequate, sufficient funds will be available to complete general facility projects as required. 10.5.2 Local Facilities Local facilities such as local distribution mains and appurtenances benefit a smaller area than general facilities. The costs for construction of these improvements can be directly attributable to the properties within an identified area which receive direct benefit from the improvements. Methods of financing local facility improvements are summarized below: • Formation of a ULID; • Developer Extension Agreement and Financing; • Local Facilities Charges (LFCs) (currently not used); • Pay -back (Latecomer) Agreements; or, • Grants and other outside assistance to reduce local costs, including City participation. Funding new local improvements through rate increases is not recommended because it would result in all customers paying improvements which benefit only a small area. Renewal and replacement of local facilities is typically financed through rates. Financing and Implementation PACE Page 10-9 City of Port Orchard 2009 Water System Plan 10.5.3 Private Facilities Individual service lines, backflow preventers and other site specific appurtenances are financed by the individual customer receiving the direct benefit from such facilities. 10.6 FINANCING STRATEGY The Capital Improvements Plan identified in Section 7 identifies approximately $22.2 million in water system improvements, including developer financed improvements. Of these improvements, approximately $15.9 million is recommended for the next six years including developer funded projects with approximately $5.8 million at least partially financed by connection charges and $6.3 million in system renewal and replacements that would be funded through rates or Local Facilities Charges. Because of the need for significant source improvements to accommodate the projected increase in population, it is imperative that growth, and water consumption be monitored closely to ensure that requisite improvements are accomplished in advance of system expansions and new connections. It is recommended that the City fund the recommended improvements in the following manner. First, any grants or low interest loans should be utilized to finance needed projects. Next, cash on hand from GFCs, LFCs, rates and any other sources of money should be utilized. Any short -fall in these funding sources required to finance the required system improvements may be obtained from selling revenue bonds. Bond issues, however, must consider available funding for repayment of the bonds. 10.7 DEVELOPER EXTENSION POLICIES The City of Port Orchard, as a municipal corporation, has a responsibility to the public to ensure that water mains installed in public streets and easements are constructed in accordance with currently accepted standards for public works. Therefore, the City has adopted a developer extension regulation which is set forth in its' Developers Handbook. The requirements set forth in that document are intended by the City as a contract with the developer, incorporating minimum standards which are prerequisite to acceptance by the City of facilities which are to become part of the City's water system. By reference, the latest version of the referenced document is incorporated into and made part of this Comprehensive Plan. 10.8 ENVIRONMENTAL REVIEW As part of this planning process and in order to comply with the requirements of the State Environmental Policy Act (SEPA), an environmental checklist has been prepared and circulated for comment. A copy of the SEPA checklist and associated Declaration of Non -Significance is contained in the Appendices to this document.

Service Request Process The City responds to requests for service on an on -going basis. If the request is for a service installation within the City limits, fees are paid and the City personnel tap the main and install the service line from the main to the property line and set the meter. If the request for service is a Developer Extension within the City limits, the Developer must complete the application to construction an extension and the application must be approved by the City. The remainder of the processes is detailed on the Developer Handbook. Service requests and Developer Extension requests outside of the City limits are handled on a case - by -case basis and coordinated with the Kitsap County building permit process. 2. System Capacity Assessment The City of Port Orchard's water system has been constructed with the capacity to accommodate additional individual service connections within the City limits and immediate surrounds. A source of supply analysis was completed as part of the City's comprehensive planning process and indicated the capacity to serve the projected population of the water service area established by the Coordinated Water System under current zoning conditions. For Developer Extensions, the City requires developers to demonstrate the ability to construct facilities sufficient capacity exists and what, if any improvements are required to provide adequate service. The City, however determines final requirements for water system improvements. 3. Additional Conditions for Service The primary policy of the City Council is that water service will be provided to properties within the city limits. If capacity is available, water service will be provided to residents of the Urban Growth Area (UGA) outside the City limits. Properties within the UGA requesting water service area are expected to annex to the City before service is provided. The City Council may consider exemptions to this policy if it is determined to be In the best interest of the community. In such instances, the City will accept a Developer's Extension Agreement which prohibits the property owner from protesting future annexation proposals. Until such time that the property is annexed, customers will pay a 50% surcharge on their water bills. 4. Time Extension and Appeal Process If needed, Developers can request time extensions for completing water service projects. Time extension requests are reviewed by the City Engineer and/or Public Works Staff. Disputes and appeals are also addressed by City Council. Attachment 9: Water Reclamation Checklist for Systems with 1,000 or more Connections The Municipal Water Supply - Efficiency Requirements Act, Chapter 5, laws of 2003 (Municipal Water Law), amended Chapter 90.46 of the Revised Code of Washington (RCW) to require public water systems serving 1000 or more connections to evaluate opportunities for reclaimed water when completing their water system plans (WSP). This checklist may be used to ensure that your WSP includes sufficient information about opportunities for reclaimed water and your system's efforts to develop those opportunities. Water System Name: City of Port Orchard Date: lanuary 2006 2004 PWS ID: 68900 Please see attached. 1. An evaluation of water reclamation opportunities is found in the WSP on pages: At a minimum, include the following in your evaluation of reclamation opportunities: • An inventory of large water users. • Identification of potential reclaimed water users. • Estimates of how much water could be saved by development of reclaimed water projects • Identification of opportunities that your system intends to pursue within the next six years • A brief analysis of the financial and operation feasibility of identified opportunities The form on the opposite side of this page is provided to assist you in conducting an inventory of potential users and estimate savings. Use of this form is optional. 2. Provide the results of that evaluation. If new or additional reclaimed water opportunities are available, include a brief description of activities you are considering undertaking or those activities you will undertake to pursue development of those opportunities. If reclaimed water opportunities are not available, include a brief description of the interaction with the local wastewater facility (or other entity within the area you serve that may be a generator of reclaimed water) to evaluate opportunities to develop reclaimed water. 3. If evaluation of water reclamation is not included because such an evaluation has been completed by the wastewater facility, or other entity, please include a copy of that evaluation. 4. If water reclamation is mandated for this water system through local government agreement, contract, local regulations, ordinances, or other mechanism, please provide a copy of the governing mechanism. 5. If reclaimed is available within the service area of your water system please include the following information: • Name of Facility • Class of Water Received (A, B, C or D) • Reclamation Permit Number • Amount of Reclaimed Water received • A brief description of how this water is used, including information on cross connection control • Date when your utility began receiving reclaimed water Attachment 9 1 March 2004 Revision City of Port Orchard Water Reclamation Information Evaluation • Large Water Users RESTAURANTS Mary Mac's Pancake House Shari's Tweten's HOSPITAL/NURSING HOMES Group Health Harrison Hospital Ridgemont Terrace Stafford Suites SCHOOLS Cedar Height Jr High Sidney Glen Elementary South Kitsap High GOVERNMENT Kitsap County Admin Bldg Kitsap County Juvenllle Home Penninsula Work Release MISCELLANEOUS Days Inn Hi Joy Bowl Holiday Inn Express South Kitsap Mall Potential Reclaimed Water Users None identified at this time. Estimate of Water Saved by Development of Reclaimed Water Projects Not Applicable. Reclaimed Water Opportunities to Pursue The City has recently completed a wastewater treatment plant upgrade with the Karcher Sewer District. Although no firm opportunities for water reuse have been identified - several Inquiries have been made. Both the City and the District support water reuse where practical, cost effective and within the If the District were to get a customer with the potential to use reclaimed water or if the District were determined reclaimed water could be a feasible option for a customer, available opportunities would be pursued. Financial and Operation Feasibility Financial and operational feasibility would need to be analyzed on a case by case basis 2. Results • Activities to Consider as New or Additional Reclaimed Water Opportunities become Available Provision of reclaimed water from the recently upgraded joint use wastewater treatment plant will be accomplished as requests are made or opportunities for reclaimed wastewater become available. • Interaction with the Local Wastewater Facility to Evaluate Reclaimed Water Opportunities As mentioned, the City and Karcher Creek Sewer District recently participated in upgrade of their joint use wastewater treatment facility. The District actually operates the plant but the City will assist in the evaluation of reclaimed water potential within its service a res. 3.
