DOCX (8/20/2019 5:17 PM) 1h EXECUTIVE SUMMARY EXECUTIVE SUMMAfly lntroductiar��i The City of Ashland (City) has a long history of successfully and proactively managing its water system. The City engaged the services of RH2 Engineering, Inc., (RI-12), to prepare a Water Master Plan (WMP) update for its water distribution system to reflect several changes to the water supplies. The WMP includes a study of the entire water system from supply to storage and distribution. To aid in the master planning effort, a hydraulic computer model was created of the distribution system. The model was used to evaluate the system to determine recommendations for capital improvements. A Capital Improvement Plan (CIP) was created which provides recommendations for improvements to meet existing and future demands. This executive summary provides a brief overview of the WMP findings and results. A brief summary of the content of the chapters in the WMP is as follows: • The Executive Summary provides a brief summary of the key elements of this WMP. • Chapter 1 introduces the reader to the City's water system, the objectives of the WMP, and its organization. • Chapter 2 presents the water service area and describes the existing water system. • Chapter 3 presents related plans, land use, and population characteristics. • Chapter 4 identifies existing water demands and projected future demands. • Chapter 5 discusses the water system analyses and existing system deficiencies. • Chapter 6 presents the proposed water system improvements with the estimated costs and implementation schedule in a CIP. • Chapter 7 summarizes the financial status of the water system and presents a plan for funding the water system improvements. • The Appendices contain additional information that supplements the main chapters of the WMP. The City owns and operates a potable water system and complies with all regulatory standards for managing a public water system in the state of Oregon. In 2018, the City provided water service to an average of approximately 8,717 customer connections in approximately 6.6 square miles. The 2018 population served by the water system was approximately 21,501. The City's primary water supplies are the East and West Forks of Ashland Creek, which are stored in Reeder Reservoir and released to the City's water treatment plant. Supplemental water supply is provided by the Talent Irrigation District (TID) and from the Talent -Ashland -Phoenix (TAP) Emergency Intertie that conveys water supply from the Medford Water Commission. Water supply from Reeder Reservoir and TID is treated at the City's water treatment plant. At the time of this WMP update, a new water treatment plant is currently in design and planned for construction in 2020 through 2022.

DOCX (8/20/2019 1:23 PM) ES-1 all EXECUTIVE SUMMARY CITY OF ASHLAND WATER SYSTEM PLAN A description of the water system is presented in Chapter 1. Water storage is provided by four treated water storage/distribution reservoirs that have a total capacity of approximately 6.8 million gallons (MG). Because of the varying topography in the City, the water system has 14 pressure zones with 31 pressure reducing stations. The system also has four booster pump stations and approximately 119 miles of water mains. Detailed descriptions of the City's water system infrastructure can be found in Chapter 2. oom i��,I� om000fl Growtl,"ioomn� The City is planning to serve all City customers within the Urban Growth Boundary (UGB) which covers 4,954 acres, or 7.7 square miles. Historic and projected populations for the City limits and Urban Growth Boundary (UGB) are provided by Portland State University's Population Research Center (PRC) and are shown in Chart ES-1. It is important to note that the latest PRC population projections are significantly less than previous water master plan projections and result in lower future demand projections. The entire UGB is assumed to be annexed into the City by the end of the 20-year planning period, consistent with the City's Comprehensive Plan.

Since 2010, the average day demand (ADD) has ranged from 2.5 to 2.9 million gallons per day (mgd); maximum day demand (IVIDD) ranged from 5.2 to 5.7 mgd. Demands vary with the seasons, typically peaking in late July or early August and result in an MDD to ADD peaking factor of 2.0.

A detailed evaluation of customer water use trends is presented in Chapter 4. utu�r--e Water Demainds Demand from future customers was estimated by multiplying the projected population growth with the per capita demand computation (125 gallons per capita per day) as described in Chapter 4. Future demand projections were computed with and without water savings expected from implementing the City's conservation goals: 5 percent by 2020, 15 percent by 2030, and 20 percent by 2050. Maximum day demand (MDD) was estimated from the projected ADD using a peaking factor of 2.0. Table ES-1 presents the projected water demand forecast for the City's water system. The City's 2040 MDD projection without conservation (4,555 gpm) equates to approximately 6.6 mgd, which is significantly less than previous demand projections for the City. Table ES-1 Future Demand Projections The evaluation of the water system, as presented in Chapter 5, is based on the 2040 projected demands without conservation reductions to ensure that the future system will be sized properly to meet all requirements, whether or not additional water use reductions are achieved. However, the City will continue to pursue reductions in water use by implementing the current conservation program. Chart ES-2 shows a graphical representation of MDD projections.

These issues are evaluated in Chapter 5 and recommendations are provided in the Capital Improvement Plan (CIP) in Chapter 6 (see also Table ES-2). C'haknge 1 qu ill i -ig firorn a Gravity Sys-t., Wm iirn t„ [ L, ii ,,,�ravi „Ly Systern The majority of the City's customers are currently served entirely through a gravity supply system. With construction of the new WTP, located lower in elevation than the existing plant, approximately half of the City's supply will need to be boosted through a new booster pump station. The size of this pump station and ongoing pumping costs can be reduced by reducing demands in the high-pressure zones. Recommendations in Chapter 5 include reducing the use of pressure regulating valves (PRVs) that supply water from higher zones to lower zones by improving transmission capacity in Granite Zone 1 and adjusting PRV settings. Eventually extending the Granite Zone 1 piping to low elevation customers to the far east of the City is also recommended to reduce reliance on the boosted Crowson Zones. These changes reduce the future required capacity of the WTP to Crowson Booster Pump Station from 4,219 gpm to 1,624 gpm (approximately 60 percent). ;;;. h m Granite 1'3�eservohr is Aging and in a Ir L,,,oca„ Lion The Granite Reservoir is in poor condition and requires major improvements to remain functional and safe.

This location is ideal for compatibility with the operations of the TAP Emergency Supply into Granite Zone 1. With construction of one or two new clearwells at the new WTP site, the storage volume for the new reservoir can be less than the existing reservoir. For many years the City has dealt with water quality challenges in the Alsing Reservoir, which is oversized for its current service area. As previously recommended, expanding the customers to which the reservoir supplies can resolve this issue. Chapter 5 recommends specific valve adjustments and new PRVs to expand the Alsing Reservoir service area.

This is because the 8-inch pipes serving the area are undersized for this amount of flow. Chapter 5 includes recommendations for increasing the pipe sizes to meet the fire flow goals and additional rezoning of the South Mountain pressure zones to provide adequate pressure to high elevation customers. ChaHenge 5: ,,,, I,,, I;;;;;;;.; rn rg n nno I, [, Crowson Zorie The TAP Booster Pump Station can supply water during an emergency to customers in the Granite Zones, which comprise approximately half of all system demands, but cannot boost water as high as the Crowson Zones. Chapter 5 recommends a new 1,000 gpm Granite-to-WTP BPS that will boost TAP Emergency Supply water to the WTP Clearwell, where it can then be boosted to the Crowson Zones using the new WTP to Crowson BPS. m Hng e m [lire s tj lire Ex-t-:rernes hn Many L -L i r'l Due to the large variation in elevations within each pressure zone, the water system has many locations of low and very high pressures. Chapter 5 includes recommendations for rezoning and future rezoning studies to address the pressure extremes. ,,,,� n : m n H i ,: mt,: ems .......... h . ii� �� ii ,,, ii� ,,, Many neighborhoods in the water system were originally built for lower fire flow rates; such as those with 4-inch diameter pipes. These areas are unable to meet the City's updated fire flow criteria to provide 1,500 gpm in residential areas and 4,000 gpm for non-residential customers. The City's updated hydraulic model was used to evaluate pipe improvements throughout the City to resolve fire flow deficiencies. Chapters 5 and 6 summarize and prioritize these projects. Storage volume evaluations in the past have identified storage deficiencies in the Crowson and Granite Zones. However, these deficiencies are highly dependent on the emergency scenario for which the City is planning. By adjusting the emergency storage volume criterion to account for the City's new redundant and reliable supply sources, the storage requirements can be reduced.

DOCX (8/20/2019 1:23 PM) ES-5 EXECUTIVE SUMMARY CITY OF ASHLAND WATER SYSTEM PLAN Chapter 5 summarizes the storage recommendations, including replacement of storage in Granite Zone 1. Despite the City's ongoing pipe replacements, many pipes in the water system are aging and are undersized for current day pressure criteria. Several pipe capacity improvements were evaluated using the hydraulic model. Recommended improvements are summarized in Chapter 6. � Capit'.`,al III � �� u l IIIUIIIIo� 11 IIUI olinUw U� ooi� �miooi � 0000il� 00000 ooi umuw Chapter 6 presents the recommended CIP for meeting the City's level of service goals of continuing to provide safe, reliable water to current and future customers. The proposed CIP projects were developed from the system analysis (Chapter 5), as well as meetings with City staff, to address current and future water demand conditions and to sustain system reliability. It is important to note that this plan represents the latest decision -making given current conditions and may likely change in the future as conditions change. The capital improvement projects are categorized as follows: • Supply Improvements • Storage Improvements • Pump Station Improvements • Pipe Improvements • Operational Improvements • Recommended Studies A summary of the City CIP is developed and presented in Table ES-2. This summary provides total probable costs, a brief description, and prioritizes each capital improvement based on recommended year of implementation. The total CIP is approximately $79M over the next 40 years, including the $31M new WTP. An additional $12M of capital projects are recommended beyond the 40-year time frame, for a total CIP of $91M. Project priorities should be considered flexible in order to accommodate concurrent construction during other street opening projects, budgetary constraints, specific development projects, and other factors that may affect project implementation. Further detail about the recommended CIP projects is presented in Chapter 6. Hansford Economic Consulting (HEC) performed a financial analysis to assess the ability of the City to finance the recommendations in this WMP. The analysis reviewed water rates and operating forecasts to identify funding gaps and make recommendations to fully fund the CIP. The study indicates that the City should increase their billing rates for %-inch meters consuming 1,000 cubic feet in a month by 4 percent by 2020. It is recommended that the City: ES-6 Z:\BOTHELL\DATA\C0A\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMP EXEC SUMMARY. DOCX (8/20/2019 1:23 PM) CITY OF ASHLAND WATER SYSTEM PLAN EXECUTIVE SUMMARY 1. Minimize the need for borrowing or sale of bonds to fund water infrastructure by strategically timing commencement of projects and by raising SDCs and rates sufficiently in advance of the need to start projects. 2. Plan for 4.0 percent rate increases for the next three years, and 4.0 to 4.5 percent per year rate increases thereafter, depending on actual revenues realized and cost of service needs. 3. Adjust the water SDCs as soon as possible to account for the revised CIP contained in this 2019 Water Master Plan Update. 4. Review available cash in the water fund annually for planned capital expenditures and adjust SDCs and rates as necessary. 5. Continue to maintain reserves of at least 2 months of revenues and one year of debt service for unforeseen costs, revenue shortfalls due to drought, emergency repairs, and so forth.

Mr. Greg Hunter, Water Treatment Plant Supervisor Contact Phone Number (..541)488-5346 In 2018, the City provided water service to an average of approximately 8,717 customer connections, or 14,750 equivalent residential units (ERUs), within the City's water service area. The City limits comprise an area of approximately 6.58 square miles, which also represents the water service area. The 2018 population served by the water system was approximately 21,501. The City's water supply is currently provided by Reeder Reservoir with supplemental water supply provided by the Talent Irrigation District (TID) and from the Talent -Ashland -Phoenix (TAP) "Emergency" Intertie that conveys water supply from the Medford Water Commission (MWC). Water supply from Reeder Reservoir and TID is treated at the City's Water Treatment Plant. Water supply from MWC is rechlorinated at the TAP booster pump station (BPS). Water storage is provided by four treated water storage/distribution reservoirs that have a total capacity of approximately 6.8 million gallons (MG). In addition, the City's water system has 14 pressure zones with 31 pressure reducing stations. The system also has 4 booster pump stations and approximately 119 miles of water main. A tabular summary of the 2018 water system data is shown in Table 1-2.

Definitiori mi Terions The following terms are used throughout this WMP. Consumption: The true volume of water used by the water system's customers. The volume is measured at each customer's connection to the distribution system. Cross Connection: A physical arrangement that connects a public water system, directly or indirectly, with facilities that could present the potential for contaminating the public water system. Demand: The quantity of water required from a water supply source over a period of time to meet the needs of domestic, irrigation, commercial, industrial, and public uses, and provide enough water to supply firefighting, system losses, and miscellaneous water uses such as hydrant flushing and non -revenue water uses. Demands are normally discussed in terms of flow rate, such as million gallons per day (MGD) or gallons per minute (gpm) and are described in terms of a volume of water delivered during a certain time period. Flow rates pertinent to the analysis and design of water systems are as follows: • Average Day Demand (ADD): The total amount of water delivered to the system in a year divided by the number of days in the year. • Maximum Day Demand (MDD): The maximum amount of water delivered to the system during a 24-hour time period of a given year. • Peak Hour Demand (PHD): The maximum amount of water delivered to the system, excluding fire flow, during a 1-hour time period of a given year. A system's peak hour demand usually occurs during the same day as the MDD. Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCHI.D0CX (8/20/2019 2:21 PM) 1-3 2W CHAPTER 1 CITY OF ASHLAND WATER SYSTEM PLAN Equivalent Residential Units (ERUs): One ERU represents the amount of water used by one single-family residence for a specific water system. The demand of other customer classes can be expressed in terms of ERUs by dividing the demand of each of the other customer classes by the demand represented by one ERU. Fire Flow: The rate of flow of water required during firefighting, which is usually expressed in terms of gpm. Head: A measure of pressure or force exerted by water. Head is measured in feet and can be converted to pounds per square inch (psi) by dividing feet by 2.31. Headloss: Pressure reduction resulting from pipeline wall friction, bends, physical restrictions, or obstructions. Hydraulic Elevation: The height of a free water surface above a defined datum; the height above the ground to which water in a pressure pipeline would rise in a vertical open-end pipe. Maximum Contaminant Level (MCQ: The maximum permissible level of contaminant in the water that the purveyor delivers to any public water system user. Pressure Zone: A portion of the water system that operates from sources at a common hydraulic elevation. For example, the 2170 Granite Zone 1 refers to one of the City's primary pressure zones, which has a reservoir with an overflow elevation of 2,170 feet. Purveyor: An agency, subdivision of the state, municipal corporation, firm, company, mutual or cooperative association, institution, partnership, or persons or other entity owning or operating a public water system. Purveyor also means the authorized agents of such entities. Supply: Water that is delivered to a water system by one or more supply facilities, which may consist of supply stations, booster pump stations, interties, springs, and wells. Storage: Water that is "stored" in a reservoir to supplement the supply facilities of a system and provide water supply for emergency conditions. Storage is broken down into the following three components, which are defined and discussed in more detail in Chapter 5: operational storage, emergency storage and fire flow storage. Water Loss: Water that is measured as going into the distribution system but not metered as going out of the system. 1-4 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCHI.DOCX (8/20/2019 2:21 PM) CITY OF ASHLAND WATER SYSTEM PLAN INTRODUCTION List of Abbreviations The abbreviations listed in Table 1-3 are used throughout this WMP.

The results of the evaluation and analyses of the existing water system are presented in Chapter 5. Water Service Ar"ea The City's primary source of raw water is the Ashland Creek watershed. In 1887 through 1890, the City installed its first water works and pipe network to serve the City's early settlers. In 1909, piping was installed to deliver water to town from the East and West Forks of Ashland Creek. In 1928, the City constructed Hosler Dam at the confluence of the West and East Forks of Ashland Creek. Reeder Reservoir, the resulting impoundment, provides 280 MG of storage for the City's water supply. Water from the reservoir is conveyed to the City's WTP located along Ashland Creek, approximately 1 mile below Reeder Reservoir. The City has an agreement with the TID to provide irrigation water that can be treated in drought years. When needed, TID water is pumped from Ashland Canal by the City's Terrace Street Pump Station up to the WTP, where it is treated with the Ashland Creek Supply. In 2016, construction of permanent facilities was completed to enable supply from the MWC to be conveyed to the City via a partnership with the cities of Talent and Phoenix; otherwise known as the TAP Supply System or TAP Intertie. E i Ling „ r Service Ara The City's existing water service area is roughly equivalent to its City limits with some water services outside the City limit boundary. The City limits cover an area of approximately 6.58 square miles with an Urban Growth Boundary of 7.40 square miles. The existing water service area is shown on Figure 2-1. The existing service area is approximately bordered by Interstate 5 (1-5) to the north, by the topography of the Siskiyou Mountain Range to the south and the west, Highway 66 to the east, with Highway 99 cutting through the middle of the City. Along the north -south axis of the system, the existing retail water service area is approximately 2.6 miles long. Along the east -west axis, the existing retail water service area varies from 1.9 to 3.8 miles wide. Along with the water service area, Ashland's city limits and urban growth boundary (UGB) are shown in Figure 2-1. Future tIII Service Ar ,,,,,,,,,, The City's UGB includes most areas of the existing water service area, as well as additional area to the northwest near the TAP Booster Pump Station (BPS) and areas to the southwest to Tolman and Neil Creeks. In order for customers or properties to be provided water, their property must be annexed into the City (although the City does have a resolution that defines the process to allow Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH2.DOCX (8/20/2019 2:15 PM) 2-1 CHAPTER 2 CITY OF ASHLAND WATER SYSTEM PLAN water service to customers with failed wells in Ashland Municipal Code 14.04.060). The UGB is approximately 7.40 square miles and is shown on Figure 2-1. The topography of the existing service area is generally rising in elevation from the northwest corners to the southern side of the city, with the highest elevations being the hillsides southwest of the Granite Reservoir. Service area elevations range from approximately 1,700 feet above sea level in the northwest to approximately 2,800 above sea level feet in the southwest portion of the service area. The City's system is located within the Rogue River watershed. Inventory of'Existing Water-adiliities This section provides a detailed description of the existing water system and the current operation of the facilities. The analysis of the existing water facilities is presented in Chapter 6. Pressure Zanes The City's highest and lowest elevation customers are separated by approximately 1,100 feet. The wide elevation range requires the water pressure be increased or reduced to maintain pressures that are safe and sufficient to meet the flow requirements of the system. The City achieves this by dividing the water system into four major service areas (named after the storage facilities that serve them), each of which contains several pressure zones as shown in Figure 2-1. The hydraulic grade in each pressure zone is regulated by reservoir levels, pressure reducing station settings, pump station settings, or a combination of these, as illustrated in the hydraulic profile (Figure 2-2). The Granite service area is comprised of three different pressure zones: 2170 Granite Zone 1; 1980 Granite Zone 2; and 2060 Granite Zone 3. The 2170 Granite Zone 1 is supplied in the southwest from the Granite Reservoir and the TAP BPS. The 2170 Granite Zone 1 serves customers within an elevation range of approximately 1,800 feet to 2,600 feet, and is situated between the northwest portion of the City to Clay Street at its most eastern point. The 2170 Granite Zone 1 has six pressure reducing valves (PRVs) supplying water to the two lower 1980 and 2060 Granite Zones. The 1980 Granite Zone 2 is supplied by five PRVs from the 2170 Granite Zone 1 and three other PRVs from the 2060 Granite Zone 3. The 1980 Granite Zone 2 serves customers within an elevation range of approximately 1,700 feet to 1,840 feet, and is the most northerly pressure zone. The 1980 Granite Zone 2 is predominantly located between the railroad to the west and Patton Lane to the east. The 2060 Granite Zone 3 is located just east of the 1980 Granite Zone 2 on Patton Lane and north of the 2170 Granite Zone 1 on Clear Creek Drive. The 2060 Granite Zone 3 is supplied by two PRVs from the 2170 Granite Zone 1, which establish pressures in the zone. The 2060 Granite Zone 3 currently serves customers within an elevation range of approximately 1,740 feet to 1,840 feet. The large Crowson service area is comprised of 8 separate pressure zones: the 2425 Crowson Zone 1; 2200 Crowson Zone 2; 2270 Crowson Zone 3; 2640 Crowson Zone 4; 2270 Crowson Zone 5; 2290 Crowson Zone 6; 2570 Crowson Zone 7; and 2610 Crowson Zone 8. 2-2 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH2.DOCX (8/20/2019 2:15 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM DESCRIPTION The 2425 Crowson Zone 1 has two separate sections divided by a small sliver of the 2170 Granite Zone 1. The westerly section of the zone is directly supplied by the WTP, while the other section of the pressure zone is indirectly supplied by the WTP via the Crowson Reservoir. The 2425 Crowson Zone 1 serves customers within an elevation range of approximately 2,080 feet to 2,440 feet. The 2425 Crowson Zone 1 has 12 PRVs supplying water to lower zones: 4 PRVs provide water to the 2170 Granite Zone 1, 1 PRV provides water to the 2270 Crowson Zone 5, 2 PRVs provide water to the 2270 Crowson Zone 3, 4 PRVs provide water to the 2290 Crowson Zone 6; and 1 PRV provides water to the 2200 Crowson Zone 2. Two PRVs can supply the 2425 Granite Zone 1 from the 2559 Alsing Zone 1. The 2200 Crowson Zone 2 is supplied with water from two PRVs; one from the 2425 Crowson Zone 1 and one from the 2290 Crowson Zone 6. The 2200 Crowson Zone 2 is the eastern most pressure zone, located between 1-5 and Hidden Lane. The 2200 Crowson Zone 2 serves customers within elevations between approximately 1,800 feet and 2,120 feet. The 2270 Crowson Zone 3 is supplied by two PRVs from the 2425 Crowson Zone 1, which establish pressures in the zone. The 2270 Crowson Zone 3 serves customers in an elevation range between approximately 1,960 feet and 2,160 feet. The 2270 Crowson Zone 3 is located just east of Ashland Creek, between Iowa Street to the south and Hargadine Street to the north. The 2640 Crowson Zone 4 is a small zone supplied with water from the South Mountain Booster Pump Station. The 2640 Crowson Zone 4 serves customers within an elevation range of approximately 2,340 feet and 2,480 feet, just south of Emma Street and north of Pinecrest Terrace. The 2270 Crowson Zone 5 is a very small pressure zone consisting of one small section of Harmony Lane, serving customers between Siskiyou Boulevard and Lit Way. The 2270 Crowson Zone 5 is supplied water from one PRV from the 2425 Crowson Zone 1 and serves customers within an elevation range of approximately 2,040 feet and 2,060 feet. The 2290 Crowson Zone 6 is provided water through the 2425 Crowson Zone 1 by four pressure reducing valves. The pressures in this zone are established by these four PRVs. The 2290 Crowson Zone 6 currently serves customers between the elevations of approximately 1,880 feet to 2,080 feet. The 2570 Crowson Zone 7 is located just east of 2610 Crowson Zone 8, which supplies the zone from a single PRV. The 2570 Crowson Zone 7 serves customers between an elevation range of approximately 2,240 feet and 2,340 feet. The 2610 Crowson Zone 8 is located towards the southwest corner of the City. The 2610 Crowson Zone 8 is provided water directly from the Park Estates Booster Pump Station and the Crowson Reservoir. This zone serves customers in an elevation range of approximately 2,320 feet to 2,600 feet. The 2610 Crowson Zone 8 serves customers predominantly along Ashland Loop Road and Morton Street. The Fallon service area consists of only two smaller pressure zones on the west side of the City: the 2586 Fallon Zone 1 and the 2470 Fallon Zone 2.

The 2470 Crowson Zone 2 serves customers in an elevation range of approximately 2,200 feet to 2,470 feet and is supplied water from the 2586 Fallon Zone 1 by one PRV. The Alsing service area also consists of only one pressure zone. The 2559 Alsing Zone 1 is located at the south end of the City between Leonard Street and Tolman Creek Road. The Alsing Reservoir serves the 2559 Alsing Zone 1, which is supplied by the Hillview Booster Pump Station. This zone serves customers within an elevation range of approximately 2,160 feet and 2,560 feet. The City's primary source of raw water is the Ashland Creek watershed. In 1928, the City constructed Hosler Dam at the confluence of the West and East Forks of Ashland Creek. Reeder Reservoir, the resulting impoundment, provides 280 MG of storage for the City's water supply. Water from the reservoir is conveyed to the City's WTP through a 24-inch diameter raw water transmission line. Treated water is conveyed to the City in a 30-inch diameter transmission line. The City also has an agreement with the Talent Irrigation District (TID) to provide additional supply. The TID supply is typically used only in drought years. When needed, TID water is pumped from the Ashland Canal by the City's Terrace Street Pump Station to the WTP, where it is treated. A third supply is the City's TAP Intertie. The TAP Supply System delivers treated water from the Medford Water Commission to the City's TAP BPS. At this location, the water is chlorinated and boosted to the 2170 Granite Zone 1 through 16-inch piping in Highway 99. A summary of the City's sources of supply is shown in Table 2-1. 2-4 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH2.DOCX (8/20/2019 2:15 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM DESCRIPTION Table 2-1 Supply Facilities Summary W a t e r mm,,, �r e a t rn e n t The City's WTP is located along Ashland Creek, approximately 1 mile below Reeder Reservoir. The WTP has a capacity of approximately 7.5 MGD, based on the plant's historical performance and input from operations staff. Prior to 1948, screening and chlorination were the only treatment given to Ashland Creek water. In 1948, a rapid sand filtration plant was built adjacent to the power generating facility, utilizing alum as a coagulant and lime for pH control. The WTP was converted to a high rate filtration plant in the mid-1960s. Ashland Creek WTP The treatment process now consists of flocculation, filtration, and disinfection. Water flows into the treatment plant from a combination of three sources: 1) diversion water from the power generator; 2) direct flows from Ashland Creek; and, 3) flows from the TID via the Ashland Canal and Terrace St Pump Station. The water flows through a flash mixing process, then to the flocculation basins. The high rate filtration plant continues utilizing alum as a coagulant to aid particle agglomeration and soda ash for alkalinity adjustment and pH control. A chlorine solution is fed immediately ahead of the flocculation tanks. The chlorine feed is adjusted in response to the water temperature. Following flocculation, the water flows through the filter beds and then into a 168,000-gallon clear well where the water is chlorinated and distributed to the system. Alum, sodium hypochlorite, soda ash, and activated carbon can be mixed with the raw water in the flash mixing tank as part of the treatment process to aid in the removal of solid particles and other contaminates. The activated carbon is used only when TID water is included in the system and the color is high. The activated carbon absorbs the organic material in the raw TID water, which improves color, taste, and odor.

Sediment from the flocculation chamber and the filter backwash waste is piped to a sludge lagoon. The six filters contain a dual media filter material of sand and anthracite coal. These filters remove the remaining particles in the water before it enters the clear well. Backwash water for the filters is pumped from the clear well.

The TID supply is typically used only in drought years. When needed, TID water is pumped from the Ashland Canal by the City's Terrace Street Pump Station up to the WTP, where it is treated with the Ashland Creek supply. To date, use of the Ashland Canal at the WTP has been for short periods only and has been accomplished with the City's current staffing level. However, in future years, the Ashland Canal may be used more frequently and for longer durations (due to anticipated climate and drought conditions). Reeder Reservoir Terrace Street Pump Station A partnership was created in 1997 between the cities of Talent, Ashland, and Phoenix to supply water to these jurisdictions from the MWC. MWC water is purchased by each city in the partnership and delivered to Phoenix and Talent via the Regional Booster Pump Station, located north of Phoenix. A 24-inch transmission main conveys water supply from Phoenix to Talent. In Talent, water is boosted at the Talent Booster Pump Station to meet the pressure requirements of the Talent water system. When needed, supply to Ashland is conveyed through the Talent BPS discharge piping, then through a 16-inch transmission main and the TAP BPS to Ashland's 2170 Granite Zone 1. 2-6 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH2.DOCX (8/20/2019 2:15 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM DESCRIPTION The TAP BPS was completed in 2016 and is located at 2073 W.

the higher pressure zone to the lower pressure zone while reducing the pressure of the water to maintain a safe range of operating pressures in the lower zone. A pressure reducing station is essentially a below -grade vault (typically concrete) that normally contains two PRVs, sometimes a pressure relief valve, piping, and other appurtenances. The PRV hydraulically varies 2-14 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH2.DOCX (8/20/2019 2:15 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM DESCRIPTION the flow rate through the valve (up to the flow capacity of the valve) to maintain a constant set pressure on the downstream side of the valve for water flowing into the lower pressure zone. Pressure reducing stations can serve multiple purposes. First, they can function as an active supply facility by maintaining a continuous supply of water into a lower zone that has no other source of supply. Pressure reducing stations can also function as standby supply facilities that are normally inactive (no water flowing through them). The operation of this type of station is typically triggered by a drop in water pressure near the downstream side of the station. A typical application of this function is a station that is only needed to supply additional water to a lower zone during a fire flow situation. The pressure setting of the control valve within the station allows it to remain closed during normal system operation and open only during high -demand conditions, like fire flows, to provide the additional supply needed. Pressure relief valves are control valves that are activated by higher than normal pressures and flow water out of the system to relieve the pressure and protect the system from over pressurization. Pressure sustaining valves are control valves between adjacent pressure zones that allow water to flow from the higher pressure zone to the lower pressure zone, provided the pressure in the higher zone remains above a certain threshold. Flow control stations allow water to flow from a higher pressure zone to a lower pressure zone at a regulated flow rate. The City's water system has one pressure relief valve station and 31 pressure reducing valve stations, as shown in plan view in Figure 2-1 and in profile view on Figure 2-2. A list of the control valve stations and related data is contained in Table 2-7.

telemetry and supervisory control system gathers information and can efficiently control a system by automatically optimizing facility operations. A telemetry and supervisory control system also provides instant alarm notification to operations personnel in the event of equipment failures, operational problems, fire, or other emergency situations. The master telemetry unit for the SCADA system is located at the WTP. The computerized system controls and monitors the entire water system, including levels in the storage facilities and pump station operations. All remote sites utilize radio transmitters and receivers that communicate with a signal repeater at Ashland Acres, which then sends the signal to the WTP.

A N D U S E A N D 0 U LA1 .......... . ION Intr-oduction The City of Ashland's Water Master Plan was last updated in 2012. The plan was developed to satisfy the Oregon Health Division (OHD) water master plan requirements as outlined in Oregon Administrative Rules (OAR) 333-61-060. The OAR requires, among other things, consistency between land use and utility plans and their implementation. This chapter demonstrates the compatibility of the City's WMP with other plans, identifies the designated land uses within the existing and future service area, and presents population projections within the City's planning area. Cornpatibility witl Others [o)Ilans Introduction To ensure that the WMP is consistent with the land use policies that guide it and other related plans, the following planning documents were examined. • Oregon Statewide Planning Goals &Guidelines - Goal 14 Urbanization -OAR 660-015-000(14) • City of Ashland Comprehensive Plan • Jackson County Comprehensive Plan it „ o iri Statewide Nanning Goa ,,,,, The State of Oregon's Statewide Planning Goal 14 addresses urbanization, with the goal "To provide for an orderly and efficient transition from rural to urban land use, to accommodate urban population and urban employment inside urban growth boundaries, to ensure efficient use of the land, and to provide for livable communities." As it pertains to water systems,. Goal 14 also states that "The type, location and phasing of public facilities and services are factors which should be utilized to direct urban expansion." BUJ r bar,i rl. �i BOL.Iirid&iry Goal 14 requires that Jackson County and the City cooperate in designating a UGB adjacent to the City's existing corporate limits. The UGB is based on a demonstrated need to accommodate long range urban population and associated housing, employment opportunities, and other uses. The current UGB is shown in Figure 3-1. Goal 14 requires that the UGB "be adopted by all cities within the boundary and by the county or counties within which the boundary is located, consistent with intergovernmental agreements." Consistency with population forecasting and plans for the provision of urban facilities and services are also required. Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH3.DOCX (8/19/2019 5:12 PM) WM CHAPTER 3 CITY OF ASHLAND WATER SYSTEM PLAN Concurrency means that adequate public facilities and services be provided at the time growth occurs. For example, growth should not occur where schools, roads, and other public facilities are overloaded. To achieve this objective, growth should be directed to areas already served or readily served by public facilities and services. When public facilities and services cannot be maintained at an acceptable level of service, the new development should be prohibited. City of Ashland Comprehensive Plan The City's Comprehensive Plan, most recently updated in June 2019, describes the City's vision of how growth and development should occur over a 20-year horizon. The Comprehensive Plan considers the general location of land uses, as well as the appropriate intensity and density of land uses given the current development and economic trends. The public services and transportation elements ensure that new development will be adequately serviced without compromising adopted levels of service. The Comprehensive Plan also discusses water conservation (Chapter XI Energy, Air and Water Conservation). Jacksori County Comprehensive Plan The County adopted its first Comprehensive Plan in 1972. Subsequent revisions resulted from the County's first periodic review approved by the Department of Land Conservation and Development (DLCD) on April 11, 1994. Since then, further revisions occur as Jackson County continues the on -going process of inventorying and analyzing data, reviewing alternative solutions, and responding to changes in local, regional, and state conditions to ensure that the plans and regulations remain in compliance with the statewide planning goals and local needs. The current version of the plan was adopted in 2015. The County"s Comprehensive Plan guides development in both urban and rural, unincorporated Jackson County and designates land use in the unincorporated UGB. Similar to the City's Comprehensive Plan, the County's plan contains planning for transportation and public facilities and services in unincorporated Jackson County. �, 1 The City limits currently encompass an area of approximately 4,240 acres, or 6.6 square miles. The City's UGB encompasses approximately 714 acres outside of the current City limits, for a total area of 4,954 acres, or 7.7 square miles. The existing retail water service area includes customers within the City limits as well as some customers outside of City limits, with areas in the UGB requiring annexation into the City limits for water service to be provided. The City's zoning, shown in Figure 3-1, guides development within the City. Zoning in the UGB but outside of the City limits is designated by the County, as shown in Figure 3-1. Approximately 79.2 percent of the area within the current City Limits or Water Service Area is designated for residential use, as indicated in Chart 3-1. Approximately 16.3 percent is designated for commercial, industrial, and mixed use, 4.4 percent is designated for Southern Oregon University, and 0.1 percent for open space. 3-2 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH3.DOCX (8/19/2019 5:12 PM) CITY OF ASHLAND WATER SYSTEM PLAN LAND USE AND POPULATION Chart 3-1 Zoning Inside City Limits Commercial/Industrial/ Within the City's unincorporated UGB and outside of the City limits, approximately 88.1 percent of the land area is designated for residential use, as shown in Chart 3-2.

The Census Bureau's 2015 American Community Survey (ACS) estimated a total of 10,372 housing units in the City, with 9,446 occupied and 926 vacant. The ACS-estimated average household size for 2015 was 2.10 persons. Existing and Future City Population The County has experience rapid population growth and extensive physical developments since 2000. The population of the County increased by approximately 18 percent from 2000 to 2018, based on Portland State University's Population Research Center (PRC) estimates. In contrast, the population of the City increased by only approximately 6 percent during the same period.

For the purposes of estimating demands, the population projections in Table 3-2 will be used, with the understanding that the entire UGB is not anticipated to annex into the City until the end of the City's 20-year planning period. The system is expected to provide service to approximately 23,630 customers by 2040. 3-6 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH3.DOCX (8/19/2019 5:12 PM) RD 0 ME 1 WATEII DEMANDS 4 a IntroductIO1011 A detailed analysis of system demands is crucial to the planning efforts of a water supplier. A demand analysis first identifies current demands to determine if the existing system can effectively provide an adequate quantity of water to its customers under the most crucial conditions, in accordance with federal and state laws. A future demand analysis identifies projected demands to determine how much water will be needed to satisfy the water system"s future growth and continue to meet federal and state laws. The magnitude of water demands is typically based on three main factors: 1) population; 2) weather; and 3) water use classification. Population and weather have the two largest impacts on water system demands. Population growth has a tendency to increase the annual demand, whereas high temperatures have a tendency to increase the demand over a short period of time. Population does not solely determine demand because different user types use varying amounts of water. The use varies based on the number of users in each customer class, land use density, and irrigation practices. Water use efficiency efforts also impact demands and can be used to accommodate a portion of the system's growth without increasing a system's supply capacity. Demands on the water system determine the size of storage reservoirs, supply facilities, water mains, and treatment facilities. Several different types of demands were analyzed and are addressed in this chapter, including average day demand, maximum day demand, peak hour demand, fire flow demand, future demands, and a demand reduction forecast based on the Water Use Efficiency program. Current Service Wa L-, e rLJ s e C �� a s s i f i c a o n s The City has divided water customers into seven different classes for billing purposes. These classes are: 1) Single-family; 2) Multi -family; 3) Commercial/Residential; 4) Commercial; 5) Municipal; 6) Governmental; and 7) Irrigation. The demand analysis that follows will report on the water use patterns of these seven user groups. Residential Population Served The population within the City limits was 21,500 in 2018, based on estimates from the Portland State University PRC. Chapter 3 contains a more detailed discussion of the City's population and household trends. As shown in Table 4-1, the City provided water service to an average of 8,717 connections in 2018. Approximately 7,712 connections (88 percent) were residential or mixed commercial/residential customers, 594 connections (7 percent) were commercial customers, 91 connections (1 percent) were municipal or governmental customers, and the remaining 320 connections (4 percent) were irrigation connections.

Table 4-1 shows the historical average number of connections, average annual consumption, and average daily consumption per connection of each customer class for the City from 2012 through 2018. As shown in Chart 4-1, the single-family class represents approximately 81 percent of all connections, but only 43 percent of total system consumption, as shown in Chart 4-2. This is due to the lower consumption per connection of single-family residential customers as compared to other customer types. As shown in Table 4-1, single-family residential customers use an average of approximately 184 gpd per connection, compared to multi -family customers that use an average of approximately 677 gpd per connection, and commercial customers that use an average of approximately 630 gpd per connection. Multiple units are typically served by one multi -family connection. The average daily consumption per unit for the multi -family class historically has been approximately 90 gpd per unit. The lower consumption of multi -family customers is expected since the average household size of multi -family units is usually less than the average household size of single-family units, and multi -family units consume considerably less water for lawn and garden maintenance. Additionally, the higher consumption of commercial customers is expected since these customers include the system's highest individual water users.

1,0651011,589 Percent of Total 17% Customer water use trends were determined from monthly metering data for the different customer types. Residential demand varies throughout the year, typically peaking in the hot summer months. Other customer types often peak at different times or have different peaking factors because their uses differ. The demand of single-family residential customers in the City generally peaks in the summer, as shown in Chart 4-3. Multi -family residential, commercial/residential, and commercial consumption also typically peak in the summer, as shown in Chart 4-4, Chart 4-5, and Chart 4-6 (note that the scales vary for each chart for clarity). Municipal and governmental consumption, shown in Chart 4-7 and Chart 4-8, do not follow consistent patterns of use from year to year. Irrigation consumption, shown in Chart 4-9, is close to zero in the winter and peaks during the hot summer months.

The relatively high summer peaking factors of the City's residential and irrigation customers are illustrated clearly in Chart 4-10. Water Supply Water supply, or production, is the total amount of water supplied to the system, as measured by the meters at source of supply facilities. Water supply is different than water consumption in that water supply is the recorded amount of water put into the system and water consumption is the recorded amount of water taken out of the system. The measured amount of water supply of any system is typically larger than the measured amount of water consumption, due to non -metered water use and water loss, which will be described more in the Water loss section. Table 4-3 summarizes the total amount of water supplied to the system from 2012 through 2018. In general, water production has grown slightly from 2012 to 2018. This slight increase can likely be attributed to development and the small population increase the City has undergone during this time period. Table 4-3 Historic Water Supply Like most other water systems, the City's water use varies seasonally. Chart 4-11 shows the historical amount of water supplied to the City's system for each month from 2012 to 2018. 4-10 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH4.DOCX (8/20/2019 2:18 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER DEMANDS Chart 4-11 Historical Monthly Water Supply As shown in Chart 4-111 water supply increases significantly during summer months, primarily due to irrigation. The City's highest water use typically occurs in July and August. On average, the amount of water supplied during these two months is approximately 30 percent of the total supply for the entire year. Suby Source Chart 4-12 shows the monthly water supply by source for 2018, a year when water was supplied from all three of the City's supply sources. Typically, water is supplied only from the Reeder Reservoir, but water is supplemented from TID and the TAP BPS when necessary to supplement Reeder Reservoir. Chart 4-13 shows the monthly water supply for 2016, a typical year when water was supplied only from the Reeder Reservoir. Chart 4-14 shows the annual water supply by source from 2010 to 2018. The years 2013 to 2015 and 2018 reflect the City's supply data during years where, due to drought or other conditions, TID and the TAP BPS were used to meet the required water demand.

There are many sources of water loss in a typical water system, including water system leaks, inaccurate supply metering, inaccurate customer metering, illegal water system connections or water use, fire hydrant usage, water main flushing, and malfunctioning telemetry and control equipment resulting in reservoir overflows. Several of these types of usages, such as water main flushing and fire hydrant usage, may be considered authorized uses if they are tracked and estimated. Although real losses from the distribution system, such as reservoir overflows and leaking water mains, should be tracked for accounting purposes, these losses must be considered water loss. A comparison of the City's water production/supply totals with consumption totals for the years 2012 through 2018 shows that for the year 2012, metered consumption exceeded metered production. This is likely due to incorrect accounting and results in the calculation of a negative water loss percentage for this year, as shown in Table 4-4. The City updated its calculation method and provided updated data for the years 2014 through 2018 as shown in the table. For the last two years, which likely are more representative of the actual system, water loss is estimated at seven percent.

The City will also continue to improve the tracking and reporting of production, consumption, and other authorized water uses (such as hydrant flushing), including coordination with the fire department. Table 4-5 presents the computation of the existing system per capita demand based on 2018 data. As shown in the upper portion of the table, the total residential population served by the City's water system in 2018 was approximately 21,500. This population served, and the City's total water consumption in 2018, were used to arrive at the existing per capita demand of 135 gpd. Table 4-5 Historic Per Capita Demand As shown in Table 4-2, in 2016, the Southern Oregon University and the City of Ashland Water Department accounted for approximately seven percent of the City's water consumption. Since these customers are not anticipated to annually increase their consumption in the future, the use of the existing system per capita demand of 135 gpd would not be accurate for projecting future demands. Therefore, an additional computation of per capita demand was performed to provide a more accurate estimate for use in forecasting future water demand. The computation of future per capita demand shown in Table 4-6 is based on a reduced proportion of demand that is likely to be more representative of the future type of demand to occur in the City's system. Specifically, the 4-14 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH4.DOCX (8/20/2019 2:18 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER DEMANDS demands for the City of Ashland Water Department and the Southern Oregon University were excluded from the total annual consumption, and an adjusted annual consumption was calculated. The estimated per capita demand of 125 gpd is used later in this chapter to forecast water demands in future years based on future population estimates. Table 4-6 Future per Capita Demand Projection -essure Zone Dernands I ler Pr Table 4-7 shows the average demand of each of the City's 14 existing pressure zones. These data were developed using the City's hydraulic model estimated demand allocations. The City's two largest pressure zones, the 2425 Crowson Zone 1 and the 2170 Granite Zone 1, account for approximately 60 percent of the total system demand.

One ERU is equivalent to the amount of water used by a single-family residence. The number of ERUs represented by the demand of the other customer classes is determined from the total demand of the customer class and the unit demand per ERU from the single-family residential demand data. Tables 4-8A, 4-86, and 4-8C present the computed number of ERUs for each customer class from 2012 through 2018. The demands shown are based on the consumption totals of each customer class. Because the City revised its accounting methodology and provided updated total consumption data as shown in Table 4-4, the sum of the consumption data for each customer class shown in Table 4-8C does not match the total consumption data shown in Table 4-4. This does not significantly impact the ERU calculation. In years where there were active industrial connections, their use was minimal and represents less than 1 ERU for the given year. The average demand per ERU from 2012 through 2018 (7-year average) was 184 gpd.

Future ERUs section. This demand per ERU value also will be used to determine the capacity (in terms of ERUs) of the existing system in Chapter 5. Average Day iir „ rl j ADD is the total amount of water delivered to the system in a year divided by the number of days in the year. The ADD is determined from the historical water use patterns of the system which can be used to project future demands within the system. ADD data typically are used to determine standby storage requirements for water systems. Standby storage is the volume of a reservoir used to provide water supply under emergency conditions when supply facilities are out of service. Yearly water production records from the City's supply sources and customer water use records were reviewed to determine the system's ADD. The system"s average day demand from 2012 through 2018 is shown in Table 4-3. Maximum Demand MDD is the maximum amount of water used throughout the system during a 24-hour time period of a given year. MDD typically occurs on a hot summer day when lawn watering is occurring throughout much of the system. In accordance with Oregon Department of Human Services design standards, the distribution system shall provide fire flow at a minimum pressure of 20 psi during MDD (i.e. maximum day demand) conditions. Supply facilities (e.g. wells, springs, pump stations, interties) are typically designed to supply water at a rate that is equal to or greater than the syste m's MDD . Future MDD is projected using historic trends of the ratio of MDD to ADD. In 2018, the City's MDD occurred on August 8, 2018, when temperatures exceeded 90 degrees Fahrenheit and were in the 90s the days before and after. As shown in Table 4-9, the demand of the system on August 8, 2018, or MDD, was 3,854 gpm. For this year, the MDD to ADD ratio was calculated as 1.92. This is consistent with the City's general trend for MDD to be roughly twice as much as ADD. For future demand projections, an MDD to ADD ratio of 2.0 is used as shown in Table 4-9. Z:\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH4.DOCX (8/20/2019 2:18 PM 4-19 CHAPTER 4 CITY OF ASHLAND WATER SYSTEM PLAN Peak Hour Demand PHD is the maximum amount of water used throughout the system, excluding fire flow, during a one -hour time period of a given year. The PHD, like the MDD, is typically determined from the combined flow of water into the system from all supply sources and reservoirs. The PHD is commonly represented as a ratio to the MDD. Because PHD is difficult to monitor, annual average ratios are not readily available. The last time PHD was determined for the City was in 2013 using five-minute interval reservoir level and water production records. The 2013 PHD:MDD ratio was determined to be 2.4. This ratio is assumed to be consistent for all other planning years and is used in PHD modeling scenarios. Table 4-9 also shows the peaking factors to be used for demand projections based on historic ADD, MDD, and PHD data. Table 4-9 Maximum Day Demands and Peaking Factors m � U� o000 �� [000��Iow 00000i � ooi mm oim Fire flow demand is the amount of water required during firefighting as defined by applicable codes. Fire flow requirements are established for individual buildings and expressed in terms of flow rate (gpm) and flow duration (hours). Fighting fires imposes the greatest demand on the water system because a high rate of water must be supplied over a short period of time, requiring each component of the system to be properly sized and configured to operate at its optimal condition. Adequate storage and supply is diminished if the transmission or distribution system cannot deliver water at the required rate and pressure necessary to extinguish a fire. General planning -level fire flow requirements were established for the different land use categories to provide a target level of service for planning and sizing future water facilities in areas that are not fully developed. The general planning -level fire flow requirement for each land use category is shown in Table 4-10. The water system analyses presented in Chapter 5 are based on an evaluation of the water system for providing sufficient fire flow in accordance with these general planning -level fire flow requirements. The fire flow requirements shown in Table 4-10 do not necessarily equate to actual existing or future fire flow requirements for all buildings, since this is 4-20 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH4.DOCX (8/20/2019 2:18 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER DEMANDS typically based on building size, construction type, and fire suppression systems provided.

Future demand projections were computed with and without water savings expected from implementing conservation measures. The City's conservation program presents a goal to reduce the system -wide average daily demand from projected non -conservation demand by 5 percent by 2020, 15 percent by 2030, and 20 percent by 2050. e Ili Iri F, ,,, recasts and Conservatiuri Table 4-11 presents the projected water demand forecast for the City's water system. The actual average daily demand data from 2018 also is shown for comparison purposes. The future ADDS were projected based on population estimates for the given years and the estimated demand per capita value of 125 gpcd. Historical average demands were grown using PRC population projected growth multiplied by the 125 gpcd. The 125 gpcd value already assumes any potential water loss, so water loss is not added in separately. The MDDs and PHDs shown were computed from the projected ADDs and the existing system peaking factors shown in Table 4-9 and Chart 4-16. The future demand projections are shown with and without estimated reductions in water use from achieving conservation goals.

This ensures that the future system will be sized properly to meet all requirements, whether or not additional water use reductions are achieved.

Individual water system components were analyzed to determine the ability to meet policies and design criteria under existing and future water demand conditions (presented in Chapter 4). The analyses below cover supply, storage, pumping, pressure zones, and distribution piping. The policies and criteria are summarized below for each analysis. Recommendations are discussed in this chapter and captured in the recommended Capital Improvement Plan (CIP) in Chapter 6. Changes i n L,,,,, ,,,,, &t l,. ,,,,,,,,,, r Mas,, r Plan Since completion of the City's last Water Master Plan, several improvements have been decided upon and implemented that influence the system analysis. These include the following: • Construction of the TAP Emergency Supply System. This new emergency supply provides MWC water to the City and makes use of the City's Lost Creek Reservoir water rights purchased for this purpose. • Construction of the New Park Estates Booster Pump Station. This pump station upgrade provides a much higher level of reliability and fire protection for customers at the highest elevations in the City and allows the City to abandon the South Mountain Booster Pump Station. • Construction of the New Terrace Street Booster Pump Station. This pump station upgrade improves the City's ability to boost TO supply in the Ashland Canal to the WTP and new WTP. • New Water Treatment Plant Decision on Capacity and Location. The new WTP is planned to be a 7.5 MGD capacity plant (expandable to 10 MGD). The location of the plant is at the granite quarry southwest of the Granite Reservoir. • Pipe Improvement Projects. Several pipe improvements have been made related to new development and improving distribution system capacity. G&rieral Sys -tern Challenges The following summarizes the overall challenges to the water system. Goals for addressing these challenges are also listed and the analyses throughout this report reflect these goals. hiir-i ,,,,,,. .. m Moving from a GravitySystem „ r„L � � era ii Ly System The majority of the City's customers are currently served entirely through a gravity supply system. With construction of the new WTP, located lower in elevation than the existing plant, approximately half of the City's supply will need to be boosted through a new booster pump station. The size of this pump station and ongoing pumping costs can be reduced by reducing demands in the high-pressure zones. This can be accomplished by reducing the use of PRVs that supply water from higher zones to lower zones and by improving the ability of the lower zones to serve low elevation customers (see Supply Analysis below for further detail). Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM) 5-1 CHAPTER 5 CITY OF ASHLAND WATER SYSTEM PLAN Goal: Reduce pumping to Crowson Zones: • Improve Granite Zone transmission capacity; o Extend piping to serve low elevation customers in Crowson Zone 6; • Reduce/eliminate PRVs supplying from Crowson or Alsing Zones to Granite Zones. h ,,,� in g 4 G iira in ii „t,v ['eservohr is Aging and ii iirn a Poor i,,,,,,, c a „,n ii o in The Granite Reservoir is in poor condition and requires major improvements to remain functional and safe. In addition, the reservoir is located in the high/flood zone of Ashland Creek, which places the reservoir at risk of flood damage and ongoing deterioration. With construction of one or two new clearwells at the new WTP site, the storage volume requirements for the Granite Zones are replaced so that the City could take this reservoir offline. However, the reservoir at its current location is important to the operation of the TAP Emergency Supply into Granite Zone 1. See Storage Analysis below for further details. Goal: Abandon the existingGranite Reservoir without compromising system y r lics: • Confirm ability of TAP system to function without a terminal reservoir; • Confirm if WTP clearwells can replace the Granite tank functionality; • Consider a new Granite Zone Reservoir. h a I I n e : Oversized ,,, I s i n [?, se rvo i t For many years the City has dealt with water quality challenges in the Alsing Reservoir, which is oversized for the current service area that it serves. The low demands on the reservoir result in poor water turnover and lead to water quality issues. The City has adjusted the Hillview Pump Station setpoints to temporarily alleviate the water quality issue by keeping the reservoir partially full. However, this is not a long-term solution and the City's total stored volume is less than it could be to support an emergency. See Storage Analysis below for further details. Goal: Expand Alsing Reservoir service area to achieve reservoir turnover. h a n „ e : I,,,,: ii lire f,,,]ow D °Mm i c i iiri c ii s at I i ii g h e s u S t o im e ir „s I" a iir k E sta t e s a in d S o u t h M o a in „La ii n Despite construction of the new Park Estates BPS, the water system cannot provide the anticipated fire flows of 2,000 gpm to hydrants in the boosted pressure zone (Crowson Zone 8). This is because the 8-inch pipes serving the area are undersized for this amount of flow. Additionally, high elevation customers at the top of South Mountain Street have very low pressures during fire flows and could be better served by the boosted zone (currently served by Crowson Zone 1). Goal: Increase pipe sizes upstream of the Park Estates BPS: • Expand Crowson Zone 8 to connect to Crowson Zone 4; • Reconnect piping for high Crowson Zone 1 customers to Crowson Zone 4. rri r n cp pCannot Crowson , na,n.e,: ,.....i,Al The TAP Booster Pump Station can supply water during an emergency to customers in the Granite Zones, which comprise approximately half of all system demands, but cannot boost water as high as the Crowson Zones.

However, neither the firm nor total capacity of the TAP BPS is able to meet ADD without conservation in the case of a WTP outage (see Figure 5-2). The City's current storage is sufficient for a short-term WTP outage but the TAP system is necessary to continue supply for an outage that lasts more than a day. Figure 5-2 presents the projected ADD with and without the planned conservation goals as presented in Chapter 2. To meet the water system redundancy goal, the City plans to expand the TAP Emergency Supply system to a firm capacity of 3.0 MGD (firm capacity is the total capacity with the largest. This capacity exceeds the projected ADD with conservation and is slightly less than ADD without conservation. Expansion of the TAP supply system entails adding an additional pump in the TAP Pump Station, adding a backup generator that is able to power the firm capacity of 3.0 MGD of supply, pipeline transmission improvements, and likely other improvements in the TAP Emergency Supply system upstream of the City's TAP Pump Station. Expansion of the TAP Regional Booster Pump Station and Talent Booster Pump Station will be evaluated in the TAP Water Master Plan to be completed in the next year with the Cities of Phoenix and Talent. These recommended projects to meet the supply redundancy level of service goal are included in Chapter 6.

However, City staff think it would be prudent to implement the cross -connection control program more aggressively; this is discussed further in the City's 2019 Operations and Maintenance Plan. The City continues to proactively prepare for the impacts of climate change on its water resources. From 2010 to 20111 the City performed an extensive long-term water supply evaluation (Water Conservation and Reuse Study (Carollo Engineers, 2011). In this analysis, the City reviewed the likely impacts of climate change on the City's main water supply: East and West Forks of Ashland Creek. According to Effects on Climate Change on Ashland Creek, Oregon (Hamlet, 2010), climate change models predict less spring snowpack and lower flows in Ashland Creek. Numerous water supply options were reviewed for how to address the risk of climate change to the City's supply while still meeting growing demands. The final recommendations from the water supply evaluation were to implement water conservation and develop either the TAP Intertie to provide supply redundancy or construct a new WTP. Additional recommendations included moving more aggressively towards acquiring additional Ashland Creek or TID water rights, performing groundwater testing, and evaluating raw water storage options such as shading, snow fencing, and silviculture practices. Since completion of the 2011 water supply study, the TAP Intertie has been developed, the City is actively developing a new WTP, and the City has implemented a successful water conservation program. The other recommendations from the study are assumed to still be relevant to the City 5-6 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM ANALYSIS for addressing the risk of climate change on the City's long-term water supply. No additional evaluations on the impacts of climate change nor an update to the long-term supply evaluation were performed with this WMP update. It is important to consider that the impacts of climate change are not limited to just Ashland Creek, but are also likely to impact the water supply sources used by the MWC and the region. Beyond continued water conservation efforts, the City's supply strategy discussed above in Water System Reliability addresses how the City plans to meet demands during low water events, eventually resulting in curtailment. New W I,,,,,,, Iritegratior-i with Existing Systern Integration of the new WTP into the City's existing system was evaluated as part of this WMP. Assumptions for the location and assumed infrastructure are based on the recommendations in Ashland Water Treatment Plant Technologies Alternatives Report (HDR, March 20, 2019) (Report). The storage components of the new WTP currently include two 0.85-MG clearwells. To save upfront costs, the City is planning to only construct one clearwell at first, and then implement the second as budget allows. Combined, the 1.7-MG capacity of the two clearwells replaces the storage requirements supplied by the Granite Reservoir (see Storage Analysis below). After reviewing alternatives with City staff, it is recommended that the City not construct a second clearwell at the new WTP, but instead construct a new Granite Zone Reservoir elsewhere in the system. As discussed in General System Challenges above, the site of the new WTP is at an elevation that results in approximately half of the City's demands located higher than the new WTP, and half located below the new WTP (Figure 5-3). Supply to the zones above the WTP require water to be boosted to these customers with a new "WTP to Crowson" Booster Pump Station. This pump station is planned to be constructed with the new WTP. Assuming an elevation of the new pump station of 2255 ft (as provided in the Report), the pump station static head should be approximately 170 ft to meet Crowson Reservoir overflow elevation (2425 ft). A total head of 200 feet was assumed for hydraulic modeling. The capacity of the new pump station depends on continued reliance of the PRVs from the Crowson Zones to the Granite Zones. Based on discussions with City staff and the output of the City's hydraulic model, the City's current water system operates to supplement the Granite Zone 1 demands through several PRVs coming from the Crowson Zone. As seen in Figure 5-3, these are PRVs 8, 9, 14, 15, 16, 18, and 20. During PHD, the supply through these PRVs can be as much as 1,400 gpm according to the hydraulic model. This indicates that the Granite Zone is relying on the Crowson Reservoir to provide PHD, which should ideally come from the Granite Reservoir where peak hour demands for the zone are stored. To minimize the size and ongoing pumping costs of the WTP to Crowson pump station, the City could implement changes to reduce the water that drains from the Crowson Zones to zones that can be supplied by gravity from the new WTP. To reduce water draining through the Crowson to Granite PRVs, the Granite Zone 1 piping requires better transmission capacity in order to maintain the hydraulic grade across the zone and thereby use the PRVs less often. The City's hydraulic model was used to simulate pipe size changes to achieve this result. Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM 5-7 CHAPTER 5 CITY OF ASHLAND WATER SYSTEM PLAN lira in iii „Le Street I,,, iii o &ir-id Vakking The first pipe identified for improvement is the main transmission supply pipe in Granite Street that supplies water from the Granite Reservoir to the Granite Zone customers. The existing Granite Street pipe is a combination of old 12-inch, 14-inch, and newer 16-inch steel pipe. The model predicts a significant drop in the hydraulic grade in this pipe during PHD. By increasing the size of this pipe, the hydraulic grade in the zone is maintained much closer to the 2170 ft gradient provided by Granite Reservoir (when full). The following options are recommended dependent on how the Granite Reservoir is addressed. The timing of these improvements will need to be balanced with the City's overall budget and other water system goals. • As long as the Granite Reservoir remains in its current location, or if the City abandons the Granite Reservoir and constructs two clearwells at the new WTP to serve the Granite Zone: o The Granite Street pipe is recommended to be a 24-inch diameter pipe from Granite Reservoir to Strawberry Lane to provide PHD to the Granite Zones. o The existing 16-inch (Granite Zone 1) and 24-inch (Crowson Zone 1) pipes in Granite Street should be reconnected in Strawberry Lane and Nutley Street to allow the 24-inch pipe to supply the Granite Zone. • If the Granite Reservoir is abandoned and a new Granite Reservoir is constructed elsewhere in Granite Zone 1: o The Granite Street pipe is recommended to be a 16-inch diameter pipe from the current Granite Reservoir site to Nutley Street to provide MDD to the Granite Zones. o Anew flow control valve would be required along the pipe to provide maximum day demands to the Granite Zones. o Piping from the new WTP to the current Granite Reservoir location is recommended to be replaced with a 16-inch diameter pipe and located in Granite Street. This replaces an aging steel pipe, improves reliability of a major transmission line, abandons two aging creek crossings, and improves the hydraulic grade of the zone. Scenic Drive iirid Nt,..j l]r ems„- I,,,, i p To reduce reliance on PRVs 8 and 9 on the west side of the Granite Zone, the pipes in Nutley Street (from Granite Street to Scenic Drive) and Scenic Drive (from Nutley Street to Wimer Street) are recommended for increasing in size to a 12-inch pipe. These projects replace aging 4-and 6-inch pipes in these streets and greatly improve transmission of gravity supplied water. This project is included in Chapter 6. Crowson ,,;;;;;;;;,,, ones n 6 Rezoning An additional long-term recommendation for reducing the pumping capacity required of the WTP to Crowson BPS is to rezone low elevation customers on the far northeast end of the City's system in Crowson Zones 2 and 6. Customers south of Ashland Street and between Clay Street and Tolman Creek Road, as well as customers in the vicinity of the Ashland Municipal Airport could all be served by Granite Zone 1 with more than adequate pressure. This will require extending the Granite 5-8 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM ANALYSIS Zone 1 piping to connect these areas; much of which is anticipated to be required as new development occurs along East Main Street. This recommendation is described further in the Pressure Zone Analysis discussed below. in 1.,' e. g lira „L iii o iri 1R%eco irn irn e in d a t,d iii o iin S u rn irn a ir Until the City can fund the above transmission projects, it is recommended that the City plan for the WTP to Crowson Booster Pump Station to have adequate capacity to meet the demands of the Crowson and Alsing Zones and provide adequate supply to the Crowson to Granite Zone PRVs under current demands. This capacity equates to approximately 3,200 gpm (see Pump Station Analysis below). (If and when the City is able to reduce all supply through the PRVs, this capacity could be reduced to approximately 1,650 gpm.) It is also recommended that the City reduce the pressure settings in the Crowson to Granite PRVs once the new WTP is constructed, according to Table 5-2 below. A second 0.85-MG clearwell is not recommended at this time, but a new 0.85-MG Granite Zone Reservoir is recommended instead —see Storage Analysis below. The Granite Street and Nutley/Scenic Drive pipe improvements are included in the recommended capital improvement plan (CIP), presented in Chapter 6. Due to the decision to construct a new Granite Zone Reservoir elsewhere in Granite Zone 1, the Granite Street pipe is recommended to be a 16-inch pipe from the WTP to Strawberry Lane. Future rezoning of Crowson Zones 2 and 6 is also included in the CIP in Chapter 6.

This section evaluates the capacity of the City's existing water storage tanks to meet the existing and future storage requirements of the system. Storage r iii t r iii Water storage is typically made up of the following components: operational storage, emergency storage, and fire flow storage. Each storage component serves a different purpose and will vary from system to system. A definition of each storage component and the criteria used to evaluate the capacity of the City's storage tanks is provided below and summarized in Table 5-3. per m,ir4 mVolume of the reservoir used to supply the water system under peak demand conditions when the system demand exceeds the total rate of supply of the sources. In the past, the City has calculated operational storage as 25 percent of MDD for the zone it serves. Another criterion is to calculate the volume needed to meet PHD that supplies to the zone are unable to meet. Also called "Equalization Storage." Emergency rage — Volume of the reservoir used to supply the water system under emergency conditions when supply facilities are out of service due to equipment failures, power outages, loss of supply, transmission main breaks, and any other situation that disrupts the supply source. Common emergency criteria in the state of Oregon is to assume emergency storage as two times ADD (approximately equivalent to one times MDD). The City's previous criteria assumed 25 percent of MDD for emergency storage. This lower criteria correlates to the City constructing a new reliable WTP. 5-10 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM ANALYSIS F i re I,,,,,,,, w Storage — Volume of the reservoir used to supply water to the system at the maximum rate and duration required to extinguish a fire at the building with the highest fire flow requirement in the zone. The magnitude of the fire flow storage is the product of the fire flow rate and duration of the operating area's highest fire flow needs. These fire flow planning goals were presented in Chapter 4. Storage AI a s III The total combined storage capacity of the City's reservoirs is 6.7 million gallons. The City's original criteria for storage requirements for operational, emergency, and fire flow are compared to the existing storage to determine storage adequacy for the planning periods, as summarized in Table 5-4. The table includes the storage surplus/deficiency. As seen at the end of the table, under the City's original criteria, the City would have an existing storage deficit of 0.37 MG and a 2040 deficit of 1.34 MG given all current storage facilities.

(0.37) (0.93) (1.34) Storage Recornmenda-tions It is recommended that the City revise its storage criteria to account for the planned and implemented system changes in the last few years. With a new emergency TAP supply connection and an upcoming robust WTP, it is recommended that the City's criteria be adjusted to reduce emergency storage. Using the second option for emergency storage noted in Table 5-3, where emergency storage volume is discounted by the capacity of redundant supply, the City would be revising its storage criteria to plan for an emergency in which the new WTP is offline and the TAP supply is online. This particular emergency is consistent with the City's supply analysis goals evaluated in this chapter. Though using a different emergency storage criterion could be seen as increasing the risk of the system, using a criterion that relies on redundant supply sources is assumed to strike the correct balance of risk and cost for the City, taking advantage of investments the City has already made to reduce risk by developing a redundant supply source. Additionally, several studies have identified options to expand the Alsing Reservoir service area thereby shifting the storage burden from the Crowson Reservoir to the Alsing Reservoir which has excess capacity and needs additional demands to improve water quality. This system change was reviewed again as part of this WMP and is further described in Alsing Reservoir Service Area Expansion below. Lastly, the City is actively promoting water conservation and the estimated reduction in overall demands should be considered. Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM 5-13 aim CHAPTER 5 CITY OF ASHLAND WATER SYSTEM PLAN Granite Reservoir is in major need of replacement or removal. A recent estimate for improvements was $560,000, but even this investment would not improve the reservoir to current day seismic standards. In discussions with City staff, it is recommended that the Granite Reservoir be eventually abandoned, and a new Granite Zone Reservoir constructed elsewhere in the system. This recommendation is largely due to the importance of the reservoir to the operation of the TAP supply system into Granite Zone 1. The recommended location of a new Granite Zone Reservoir is in the northwest of the City above Schofield Street and Lakota Way and in the vicinity of Ashland Mine Road. It is recommended that the City pursue purchasing property in this area. This location is ideal for the TAP supply discharge and could take advantage of new piping required for serving new development in this area. An 0.85-MG Reservoir with an overflow of 2170 ft was assumed in all future hydraulic modeling. The reservoir and recommended pipe connections are included in the CIP in Chapter 6. As discussed earlier, the design for the new WTP includes one 0.85-MG clearwell initially that will serve as system storage and the second 0.85-MG clearwell is no longer recommended. Table 5-6 presents the final storage evaluation considering replacement of the Granite Reservoir and addition of the 0.85-MG clearwell at the new WTP. 5-14 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM) CITY OF ASH LAND WATER SYSTEM PLAN WATER SYSTEM ANALYSIS Table 5-6 Storage Evaluation— New 0.85-MG Granite Reservoir &New 0.85-MG Clearwell 111P " Him I !7! ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... ................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 2020 2030 2040 CROWSON ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... .................................................................................................................................................................................................................................GRANITE 0.37 0.38 0.30 0.24 0.27 0.08 ALSING ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... .................................................................................................................................................................................................................................FALCON 0.43 0.48 0.42 0.29 0.29 0.28 TOTAL SYSTEM 1.33 1.42 ................................................................................................................................................................ 1.08 ..................................................................................... A��sing Reservoir Service Area Expansion The City has evaluated options for expanding the Alsing Reservoir Service Area over many years. These recommendations were re-evaluated herein. To improve water quality in the Alsing Reservoir, it is recommended that the service area be expanded to serve customers south of Siskiyou Boulevard and all of Crowson Zones 2 and 6. Figure 5-4 shows the recommended Alsing Reservoir Service Area Expansion with required infrastructure and recommended valve closures. Specific locations of valve reconnections should be confirmed with City staff. As seen in Figure 5-4, the recommendation includes one new PRV station, pipe improvements, and several valve operational changes. These recommendations are described as follows: • Tolman Creek Road/Siskiyou Boulevard PRV —This PRV station serves to maintain pressures in the Alsing Zones in the upper Tolman Creek Road area, while allowing the Alsing Reservoir water to drain to portions of Crowson Zone 1, which connects to Crowson Zones 2 and 6. In the hydraulic model, the proposed Tolman Creek Road PRV was set to 60 psi, resulting in a hydraulic grade line of 2270 ft (just slightly less than Crowson Zone 6 at 2290 ft). • Tolman Creek Road Pipe —To supply the commercial fire flows (4,000 gpm) in the Crowson Zones 2 and 6, the 8-inch piping in Tolman Creek Road above the new PRV is recommended for upsizing to a 12-inch pipe. • Valve Modifications —The Alsing expansion recommendation takes advantage of existing parallel pipes in Siskiyou Boulevard while keeping the south pipe for Crowson Zone 1 and the north pipe used for the expanded Crowson Zone 6. To do this, the following valve modifications are recommended: o Deactivate PRVs 18, 23, 26, 27; o Open valves in Tolman Creek Road and Jacquelyn Street isolating Crowson 1 from Crowson 6 as shown in Figure 5-4; o Close valves along Siskiyou Blvd to isolate the expanded Crowson Zone 6 from Crowson Zone 1 as shown in Figure 5-4; o PRVs 17 and 19 are still assumed active PRVs to Crowson Zones 5/6.

Rezoning the northern section of Crowson Zone 6 and the airport area in Crowson Zone 2 is also recommended (see Pressure Zone Analysis below) but is not required as part of the Alsing zone expansion. The following summarizes the recommended supply improvements: • Revise storage criteria to account for redundant system supplies. • Expand the Alsing Reservoir Service Area as recommended. • Construct one 0.85-MG clearwell at the New WTP to serve the Granite and Crowson Zones. o As long as PRVs from Crowson to Granite are set to provide fire protection pressures, fire volume for Granite can be stored in the Crowson Reservoir. • As budget allows, abandon Granite Reservoir and plan for construction of a new 0.85-MG reservoir in the vicinity of Ashland Mine Road and Lakota Way. o Pursue property acquisition in this area. There is potential for a property trade with development. • Continue water conservation efforts.

Table 5-9 compares the required pumping capacities to the firm capacity of the existing pump stations to identify any deficiencies. The results for each pump station are described below. The 2020 required capacity of the new WTP to Crowson BPS is estimated to 3,200 gpm to meet current day demands of the Crowson, Alsing, and Fallon Zones and approximately 1,400 gpm of demand estimated through the Crowson to Granite PRVs. This capacity could increase to as much as 4,219 gpm by 2040 (the model predicts increased supply through the Crowson to Granite PRVs as overall system demands increase). Depending on if and when the City is able to reduce the need for the Crowson to Granite PRVs, and if the City rezones lower portions of Crowson Zones 2 and 6 to be served by the Granite Zone (discussed in Pressure Zone Analysis below), the pump station's 2040 capacity could be reduced from 4,219 gpm to 1,624 gpm. To be conservative and to reflect that the City may be unable to modify the use of the Crowson to Granite PRVs for many years, it is recommended that the New WTP to Crowson BPS be sized for the ability to meet 2030 demands and a reduced Crowson to Granite PRV supply that reflects the adjusted PRV settings noted in Table 5-2. This capacity equates to approximately 3,200 gpm (which is similar to the 2020 required capacity with no system changes). It is also recommended that the pump station be designed to have a reduced future capacity of approximately 1,650 gpm to reflect future rezoning and the reduction in use of the PRVs. The Hillview Pump Station is aging (almost 40 years old) and warrants replacement in the next 10 years. As seen in Table 5-8, the Hillview Pump Station capacity requirements greatly increase (from 89 gpm to 859 gpm) with the recommended Alsing Reservoir Service Area Expansion. The existing pump station meets the City's criteria through 2040 without expansion of the zone but will be deficient in meeting MDD if the Alsing Reservoir Service Area expands as seen in Table 5-9. With the planned expansion (recommended in the next ten years), the pump station capacity should be sized to provide approximately 860 gpm of MDD to the Alsing Reservoir. When the City rezones portions of Crowson Zones 2 and 6 (assumed to be beyond ten years), the pump station required capacity is estimated to be 677 gpm. The South Mountain BPS is aging and does not currently meet the City's criteria for providing fire flow to its customers in Crowson Zone 4. Part of planning for the Park Estates BPS included extending piping from Crowson Zone 8 to supply Crowson Zone 4, thereby allowing the City to abandon this pump station. The City is currently in the design process of constructing a pipe connecting Morton Street piping to Ivy Lane piping. This pipe is included in the CIP and this pump station is recommended for abandonment in the short-term.

This pump station is herein called the "Granite to WTP BPS". The new WTP to Crowson BPS could then boost water to the Crowson Reservoir that serves all of the highest pressure zones. An ideal location for the pump station would be in the Granite Street pipe and in parallel with a new flow control valve from the WTP to the Granite Zone. The Granite to WTP BPS requires a static head of 95 ft (assuming a clearwell overflow elevation of 21255 ft and a Granite Zone 1 hydraulic grade of 2,160 ft). Capacity of the pump station should meet the projected ADD of the Crowson, Alsing, and Fallon Zones; this is estimated at 1,000 gpm. This project is included in the CIP in Chapter 6. u III p S„ tation Recommendat.-Jons • The new WTP to Crowson BPS should have a firm capacity of approximately 3,200 gpm to supply the Crowson and Alsing Zones. The pump station should be designed for a future reduced capacity of approximately 1,650 gpm. • Replace the Hillview BPS to bring this pump station to current design standards and meet demand requirements of the Alsing Reservoir Service Area expansion. o Recommended capacity: 680 to 860 gpm • Abandon the South Mountain BPS concurrent with pipe installation that connects Crowson Zones 4 and 8.

Pressures within a water distribution system are commonly as high as 120 psi, requiring pressure regulators on individual service lines to reduce the pressure to 80 psi or less. It is difficult for the City's water system (and most others) to maintain distribution pressures between 40 and 80 psi, primarily due to the topography of the water service area. The City has adopted the following service pressure criteria, which are consistent with industry standards: • Minimum Pressure (during Peak Hour Demand): 30 psi • Minimum Pressure (during Fire Flow): 20 psi • Maximum Pressure: 120 psi Irk u re Zone Ar4ysis Table 5-10 lists each of the City's pressure zones, the highest and lowest elevation served in each zone, and the minimum and maximum distribution system pressures within each zone based on maximum static water conditions (full reservoirs with no demand). While this table presents the results of the pressure evaluations based on the adequacy of the pressure zones under static conditions, the hydraulic analysis section later in this chapter presents the results of the pressure evaluations based on the adequacy of the water mains under dynamic conditions. As seen in the table, many pressure zones exceed the maximum pressure to customers. This is due to the complex topography and pipe networking within the City.

Hydraulic analyses of the existing system were performed under PHD conditions to evaluate its pressure capabilities and identify system deficiencies. The existing system was also analyzed under MDD conditions with fire flow demands to evaluate the fire flow capabilities. Additional hydraulic analyses were then performed with the same hydraulic model under future PHD and MDD conditions and with the proposed improvements to demonstrate that the identified improvements will eliminate the deficiencies and meet the requirements far into the future. The following is a description of the hydraulic model, the operational conditions, and facility settings used in the analyses. As discussed in the Pressure Zone Analysis section of this chapter, ideal water pressures delivered to customers are in the range of 40 to 80 psi, and the City's criteria is to deliver pressures between 30 and 120 psi. Hydraulic Model A computer -based hydraulic model of the existing water system was updated to version 8i of the WaterGEIVIS8 program (developed by Bentley Systems, Inc.) with the City's most recent GIS shapefile, to reflect the best-known information on distribution system geometry and pipe characteristics, including diameter, material, and installation year. This was further refined to include the latest construction projects and changes to the system. Hydraulic model pipe roughness coefficients were initialized with computed estimates based on the water main material and age information from the City's water main GIS shapefile. Based on the premise that the internal surface of water mains becomes rougher with age, older water mains were assigned higher roughness coefficients than newer water mains. The hydraulic model of the existing system contains demands based on 2014 individual customer meter water demand data provided by the City. Demand data for each parcel was distributed to the closest representative junction node of the model based on the recorded usage. These demands were increased to represent 2020 demands. The peaking factors shown in Chapter 4 were used to analyze the system under PHD and MDD conditions. 5-24 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM ANALYSIS The hydraulic model of the existing system contains all active existing system facilities. The facility settings for the pressure analyses corresponded to a PHD event in the water system. All sources of supply were set to operate at constant rates (i.e. MDD). Reservoir levels were modeled to reflect full utilization of operational storage. The hydraulic model for the fire flow analyses contained settings that correspond to MDD events. All sources of supply were set to operate at constant MDD rates, and the reservoir levels were modeled to reflect full utilization of operational, emergency, and fire flow storage based on the maximum planning -level fire flow requirement. The model was calibrated as part of this WMP. Calibration is achieved by adjusting the roughness coefficients of the water mains in the model so the resulting pressures and flows from the hydraulic analyses closely match the pressures and flows from actual field tests under similar demand and operating conditions. Initial Darcy-Weisbach roughness coefficients were entered in the model based on computed estimates of the coefficients from available pipe age and material data. For example, older water mains were assigned higher roughness coefficients than new water mains; thereby assuming that the internal surface of water pipe becomes rougher as it gets older. The model was calibrated using 25 hydrant flow tests performed in the system in the spring of 2016. The model is considered calibrated when model results are within 10 percent of the field results. After identifying a few closed/partially closed valves in the system and adjusting roughness coefficients, the modeled results closely match (within 10 percent) the field results for all 25 tests; therefore, the model is considered adequately calibrated for use in the following system analyses. Hydraulic Analysis Pressure and fire flow analysis of the existing system were performed using the model for 2020, 2030, and 2040. f1ressure Anabysis Figure 5-5 presents a map of system pressures color coded by pressure range during PHD. As seen in the map, low pressures exist at several high elevation customers. City staff indicate that some customers at high elevations have their own booster pump stations to gain additional water pressure. Additionally, the model predicts many locations of high pressures exceeding 120 psi at low elevation customers. The recommendations described above in Pressure Zone Analysis should alleviate several of these high-pressure areas. Ii r,,,,,, ,,,,,, i Fire flow demands were assigned to the water system based on land use and the City's fire criteria presented in Chapter 4 and are shown in Figure 5-6. Maps of fire flow results are shown in Figure 5-7. The maps are color coded to show if each junction in the system satisfies, does not satisfy, or is within 10 percent of delivering assigned fire flows (10 percent is within the error of the model). Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM 5-25 CHAPTER 5 CITY OF ASHLAND WATER SYSTEM PLAN The map shows many deficiencies in meeting the City's fire flow criteria. This is due to a few factors: • High elevation customers within a zone are unable to maintain 20 psi during a fire flow elsewhere in the zone. This can be solved by rezoning high elevation customers. • Many pipes were built before more stringent fire codes were adopted. Fire districts commonly classify buildings in these areas as "existing non -conforming," and since they met previous fire code requirements when they were constructed, improvements to these areas are considered a low priority. Resolving these deficiencies will require implementing larger diameter pipes over time as budget allows. The modeling predicts several locations where the available fire flow is below 750 gpm, which has been used in the past by other water utilities as a minimum fire flow for residential areas. Pipe improvements to address fire flows that were significantly below the City's new fire flow criteria were prioritized in the recommendations presented in Chapter 6. It is important to note that this Water Master Plan predicts several more deficiencies than the previous WMP because fire flows were assigned at every hydrant in the system, whereas they were previously only assigned in some locations. Distribution Recommended pipe improvements to address the pressure and fire flow deficiencies are presented in Chapter 6 (Table 6-3). The general recommendations are as follows: • Implement recommendations as described in the Pressure Zone Recommendations section. • Upsize local pipes from 4- and 6-inch pipes to 8-inch pipes and larger. • Increase transmission capacity in the 2170 Granite Zone 1. o Replace the upper section of 2170 Granite Zone 1 transmission main (from new WTP to connection to Strawberry Lane). o Extend transmission capacity of 2170 Granite Zone 1 in East Main Street to serve low elevation customers and new growth to the east of the system. o Other Granite Zone transmission improvements. Other recommendations include the following: • Set PRVs from Crowson and Alsing Zones to Granite Zones to only supply fire flow. • To reduce reliance on PRV 20 (Siskiyou Blvd and Normal Ave), which appears to provide needed supply to the zone during fire flows according to the City's model, extending Granite Zone piping in East Main Street from Siskiyou Blvd to Walker Road is recommended. Additionally, increasing the transmission pipe in Siskiyou Blvd from 8-inch to 12-inch is recommended to improve fire flow to SOU and apartment complexes in the Wightman and Iowa Street areas. 5-26 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH5.DOCX (8/20/2019 2:17 PM) CITY OF ASHLAND WATER SYSTEM PLAN WATER SYSTEM ANALYSIS IM a m III III .,�;:; n Ian C !

System facilities, including source, storage, and pumping, can be controlled with the telemetry system. At the WTP and on remote computers, City staff can monitor and control supplies, reservoir levels, and pump station flows. The system communicates to all facilities using radio towers. SCADA system hardware and software require regular maintenance and occasional replacement. There are no significant deficiencies with the existing telemetry/SCADA system; however, some minor changes would improve operations and management. As part of the new WTP updates, the City is reviewing alternatives to the current SCADA software system, which requires several third -party applications to achieve the functionality desired by City staff.

I [`�11 D Clo Dili 0 1� This chapter presents the recommended Capital Improvement Plan (CIP) for meeting the City's level of service goals of continuing to provide safe, reliable water to current and future customers. The improvements described below were developed from the system analysis described in Chapter 5, as well as interviews with City staff, to address current and future water demand conditions and to sustain system reliability. It is important to note that this plan represents the latest decision -making given current conditions and may likely change in the future as conditions change. The capital improvement projects are categorized as follows: • Supply Improvements • Storage Improvements • Pump Station Improvements • Pipe Improvements • Operational Improvements • Recommended Studies A summary of the City CIP is developed and presented in Table 6-2. This summary provides total probable costs, a brief description, and prioritizes each capital improvement based on recommended year of implementation. Project priorities should be considered flexible in order to accommodate concurrent construction during other street opening projects, budgetary constraints, specific development projects, and other factors that may affect project implementation. The following sections include the basis for the cost estimates, a brief description of each improvement, and the recommended prioritization and schedule for implementation. Cost Estir'Tiate Planning level cost estimates were prepared for the recommended projects following the American Association of Cost Estimators (AACE) Class 5 estimates, which assume 0 to 2 percent of project definition as appropriate for master planning. This level of opinions of cost are assumed to be within the range of plus 50 percent to minus 30 percent of the average of contractors' bids. The estimated costs of the facilities should be expected to change along with the accuracy of the estimate as a project proceeds into preliminary and final design. These opinions of probable cost are based on year 2019 dollars and no allowance has been made for inflation in future years. Since construction costs change periodically, an indexing method to adjust present estimates in the future is useful. The Engineering News Record (ENR) Construction Cost Index (CCI) is a commonly used index for this purpose. The CCI used for this study is 11230, the May 2019 20-Cities Average. For comparison the last Water Master Plan CCI for September 2011 was 9030. Thus, costs are assumed to be approximately 25 percent higher than estimated in the previous Water Master Plan. Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH6.DOCX (8/20/2019 1:21 PM) 6-1 CHAPTER 6 CITY OF ASHLAND WATER SYSTEM PLAN Estimated total project costs for each project are comprised of multiple components: directly estimated construction costs, an allowance for contingencies, and an allowance for engineering, legal, and administrative costs. These components are described below. Construction Costs Planning -level construction costs were estimated assuming a traditional public works procurement process of design, bidding, award, and construction by a licensed contractor using commonly accepted means and methods. Property easements or land acquisition and maintenance costs are not included. Table 6-1 presents the unit construction cost assumptions for pipe improvements used in the CIP. These are based on recent, local projects and include mobilization, materials, labor, contractor overhead and profit, and all elements expected to be included in a contractor's bid. Pump station costs were estimated using previous projects and comparing building square footage, total motor power, ultimate capacity, and startup capacity.

In brigencies A contingency of 30 percent was added to estimated construction costs for all projects except small pipe improvement projects that require minimal traffic disruption. The allowance for contingencies covers items such as variations in the project configuration, which are developed during preliminary design and final design, unforeseen site conditions encountered during construction, and reasonable project changes during construction. The contingency allowance does not include major project scope additions or additional costs resulting from permit mitigation requirements (such as wetlands enhancement). mm. ,,,, III I neer I I „, I,,,,,,,. g � " rn I III III III -° a t III o lia Total construction costs were increased by 25 percent to achieve the total project cost.

Some projects are recommended for capacity upgrades and maintenance or other non -growth -related reasons. The portion eligible for SDC funding was calculated as the additional cost for increasing capacity. Chapter 4 presents the current and future estimated ERUs for the water system. New ERUs comprise approximately 10 percent of all total 2040 ERUs; thus, an SDC allocation of 10 percent was assigned to several projects where general infill is anticipated. In other projects, the SDC eligibility is greater due to the project specifically benefitting future growth. A few pipe projects (P-20,. P-28 through P-32) were identified to serve future development areas and are assumed to be installed by developers when development occurs. These projects are noted in Table 6-3. [)lro j"ect As described in Chapter 5, the City's water system has several challenges to overcome that will take many years and significant funding to resolve. The following prioritization was assigned to the recommended projects: 1. Currently planned projects for the next two years and including the new WTP and its required associated facilities. 2. Projects that resolve significant fire flow deficiencies. (These are defined as fire flows that are approximately 50 percent below the fire flow criteria when in a non-residential area. These projects are labeled as "Fire Flow 1" in the notes in Table 6-3 and are prioritized for the next twenty years.) a. Projects that correct low pressure conditions causing fire flow deficiencies elsewhere in a pressure zone. 3. Projects that reduce supply from the Crowson to Granite zones (thereby reducing pumping to Crowson). 4. Projects that correct high pressure conditions. Schedule �uu Improvements The recommended projects were added to an implementation schedule that can be used by the City for preparing its CIP and annual water budget. The implementation schedule for the proposed improvements is shown in Table 6-2. As seen in the table, projects are allocated into Short -Term, Mid -Term, and Long -Term schedules. The Short -Term shows projects allocated annually for the next ten years. The table also shows the calculated SDC eligibility. Descri P stian ofirrqar-overnents This section provides a general description of the recommended improvements and an overview of the deficiencies they resolve. Most of the improvements are necessary to resolve existing system Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH6.DOCX (8/20/2019 1:21 PM) 6-3 CHAPTER 6 CITY OF ASHLAND WATER SYSTEM PLAN deficiencies. Improvements have also been identified for serving future growth. Recommended infrastructure improvements for Short -Term, Mid -Term and Long -Term planning periods are shown in Figures 6-1, 6-2 and 6-3, respectively. Supp�y Impl,"overnents The following improvements are recommended for the City's supply system. The City is already planning on the majority of these projects and City staff provided costs. Costs and timing of supply improvement projects are shown in Table 6-2. S,,,,,,. ,,,. [ iim Safeii ,,)lirovernen L The City recently completed its Federal Energy Regulatory Commission (FERC) Part 12 inspection of Hosler Dam and associated appurtenances. The Part 12 inspection and associated Potential Failure Modes Analysis Update (PFMA) details areas of concern with the dam. This project covers the cost of developing a plan and schedule, and further evaluation and potential improvements of the spillway structures and dam piping penetrations. The City has determined that this project is 25 percent SDC eligible. �, � ° ,,,, h � n ("M;;; Cn � I,,,, iii iii [.` it j The City has secured a $1.3M loan from the Department of Environmental Quality Clean Water State Revolving Fund Loan to improve creek health by piping the Ashland Canal. This project includes piping approximately 10,000 feet of canal for both water quality and conservation purposes. The City has determined that this project is 100 percent SDC eligible. The East and West Forks transmission lines are critical for providing raw water supply to the City while dewatering Reeder Reservoir for repairs or sediment removal. Several segments of these pipes are in need of repair, including two crossings of the reservoir. The City has determined that this project is 75 percent SDC eligible. ,,,,,,, ,,,,,,,, m [ der [rvoir kritake [, a ii airs Recent water quality studies identified the need to be able to draw water supply from different depth levels of Reeder Reservoir during different times of the year. This will allow the City to better manage raw water quality for treatment of potable water and temperature control for wastewater effluent. The City has determined that this project is not SDC eligible. S,,,,,,. 5 m Reeder Reservoir Sed i m&i-i R- r ova To meet regulatory requirements for sediment in Reeder Reservoir, the City must manage ongoing sediment removal in the upper dams that flow into the reservoir every three to four years. The City has determined that this project is 75 percent SDC eligible. 6-4 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH6.DOCX (8/20/2019 1:21 PM) CITY OF ASHLAND WATER MASTER PLAN CAPITAL IMPROVEMENT PLAN S.,,,,. m 7.5 D Wa Le II ,,,,,,I,,,,,, reatmeni „L ` � a Il i The City is already under design of the new WTP that replaces the existing WTP that is in major need of replacement. This significant project will build in critical water supply reliability and resilience. The project includes a new WTP, clearwell, pump station, and associated piping to connect to the water system. The new WTP is planned for construction at a site southwest of the Granite Reservoir on City property. The City has determined that this project is 10 percent SDC eligible. ,,,,,,,,,,,,,,,, , W I,,,,,, I" Back [�ecove lipy Syste lrn A follow up project to the new WTP is additional mechanical and structural components at the plant to allow the City to reuse filter backwash water, thereby reducing water waste. This project is assumed to be delayed until funding is available. Similar to the new WTP, this project is assumed to be 10 percent SDC eligible. It is anticipated that the City will have some responsibility in the investment of improvements to the TAP Supply System from the connection at MWC to the City's TAP BPS. The City, along with the Cities of Phoenix and Talent, are preparing a TAP Water Master Plan in FY20 to review infrastructure capacity and maintenance needs. Costs for the resulting recommendations are unknown at this time. However, the City's cost share is expected to be approximately $50,000 and is anticipated in the short-term to support pipe relocation required by an ODOT project on the TAP transmission main in Phoenix. This project is assumed to be 10 percent SDC eligible. .,,,,. : [.) e r re .,F I,,,, � rn p rove rn e lien „I, f)rojects To save upfront costs, the City anticipates deferring other ancillary WTP improvements that can be delayed until funding is available. The first project is anticipated for FY27. „ torage Improvements The following water system storage improvement was identified from the results of the water system analyses in Chapter S. As soon as budget allows, it is recommended that the City abandon the existing Granite Reservoir, which is in poor condition and in need of costly repairs and construct a new reservoir in the vicinity of Ashland Mine Road. A new 0.85-MG Granite Zone Reservoir in this location continues to serve as Granite Zone storage and provides terminal storage for the TAP supply into Granite Zone 1 so that the TAP BPS does not have to meet PHD of the Granite Zones. New development is anticipated to occur in the vicinity of the recommended location, thus cost savings could be achieved by combining new pipes for development with connections to the new reservoir. Pipe projects P-20 through P-22 are recommended to support the new Granite Street Reservoir. Additionally, pipe project AP-1 (Fox Street Pipe) is recommended to be a 16-inch (previously planned as an 8-inch pipe). Figure 6-2 shows the approximate location for this reservoir and the associated piping. Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH6.DOCX (8/20/2019 1:21 PM) 6-5 2W CHAPTER 6 CITY OF ASHLAND WATER SYSTEM PLAN rn p Sto t i o n I rim e t „ The following pump station improvements were identified from the results of the water system analyses in Chapter 5. The improvements are primarily necessary to resolve existing system deficiencies, but also have been sized to accommodate projected growth. The project costs for pump stations in Table 6-2 are for the pump stations only and do not include costs of new pipes. Provide backup power to TAP BPS by 2024. This project is assumed to be 10 percent SDC eligible. Replace this aging booster pump station and increase capacity to support the Alsing Reservoir Service Area expansion. The recommended capacity is 860 gpm, with the ability to be reduced to 680 gpm. This project is anticipated to be 8 percent SDC eligible, which reflects the additional growth in the expanded Alsing Reservoir Service Area. Provide a new booster pump station to boost water from the Granite Zones to the new clearwell at the WTP. This project allows the emergency TAP supply to be boosted to the upper pressure zones (in combination with the WTP to Crowson BPS). A 1,000 gpm pumping capacity with a static head of 95 feet is recommended. The project is recommended to be located in Granite Street in parallel with a flow control valve that supplies the Granite Zone from the WTP. This project is anticipated to be 10 percent SDC eligible. F')ipe Improvements The following water main improvements were identified from the results of the distribution and transmission system analyses discussed in Chapter 5. All recommended improvements are assumed to be Ductile Iron Pipe Class 54 following the City's pipe construction standards. The improvements are sized to meet future demands; thus, many projects include an SDC allocation. The projects were prioritized according to the prioritization discussed above and were allocated in the planning years such that the total pipe project costs are approximately $1M per year. This is consistent with the City's latest budget planning. It is important to note that the recommended pipe improvements do not resolve every pressure or fire flow deficiency in the water system as predicted by the hydraulic model. The number of pipe projects identified to address significant fire flow issues as well as other critical transmission projects require over $30M over the next 30 years. Thus, it was assumed that additional pipe projects to resolve every deficiency would require budgeting beyond the planning periods presented herein. through''.... m Annt4 I` ipe Repacement Proposed CIP projects AP-1 through AP-25 are a group of pipe improvements which address aging, undersized pipes, many of which could be implemented by City staff.

The City has adopted an annual pipe replacement budget of $300,000. The recommended projects are summarized in Table 6-4 at the end of this chapter and into a single line -item on the CIP summary shown in Table 6-2. The projects were placed in priority of those that resolve significant fire flow deficiencies.

This project may be done in phases (i.e. Granite Reservoir to Strawberry Lane, then WTP to Granite Reservoir) or could be a single project when the Granite Reservoir is taken offline. This project is identified to be completed in the mid-term; however, completing this project as soon as budget allows is recommended in order to reduce pumping from the WTP to Crowson Zone 1. A series of pipe projects in East Main Street from Siskiyou Boulevard to the east side of Interstate 5 (I-5) at Ashland Street /Oak Knoll Drive is recommended. T-3 and T-4 are 16-inch mains. T-3 provides needed transmission capacity within Granite Zone 1 to supply fire flows to Southern Oregon University and the apartment complexes in the Wightman Street and Iowa Street vicinity. Project T-3 could also be used as a way to separate high pressure customers north of East Main Street as part of a rezone project. T-4 is recommended to provide a redundant supply to new development in the Normal Avenue area north of East Main Street. T-5 is a 12-inch main to supply Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH6.DOCX (8/20/2019 1:21 PM) 6-7 CHAPTER 6 CITY OF ASHLAND WATER SYSTEM PLAN areas of Crowson Zones 2 and 6 that are recommended for rezoning to the Granite Zone. This pipe could also be constructed to serve development east of 1-5 and south of East Main St. Operations and Mairiteriance The following operations and maintenance improvements are recommended and are shown in Table 6-2. This project is recommended for expansion of the Alsing Reservoir Service Area. The timing of the project is recommended to be concurrent with replacement of the Hillview BPS. This project is estimated to be 8 percent SDC eligible, which corresponds to projected growth in the expanded Alsing service area. City staff have identified the need for funding of a hydrant replacement program to bring hydrants throughout the City into improved, more reliable conditions for fighting fires. An annual budget of 10 hydrants per year is recommended for the first ten years (except for the first two years), and 20 per year beyond this. This program is not assumed to be SDC eligible. As discussed in Chapter 5, the City's telemetry system will require infrastructure improvements to keep up with improved technologies and to match the system decided on for the new WTP. This project is assumed to be 10 percent SDC eligible. OM 4- AK/AMf� Eva�uation The water system includes a combination of meter types, including typical manual read meters and some automatic meter read (AMR) meters. To simplify monthly meter reading and meter maintenance, have a consistent meter type is recommended. City staff need a plan for whether to continue to install and repair AMR meters or consider other technologies. Other meter technologies, such as advanced metering infrastructure (AMI) would need to be reviewed and approved with public input as the community is concerned with potential environmental impacts associated with these technologies. A study is recommended for evaluating and recommending a meter type for the City to move forward with meter management. This project is assumed to be 10 percent SDC eligible.

Costs are unknown at this time, but a cost of $200,000 is a placeholder until the costs can be further refined. This project is assumed to be 10 percent SDC eligible. 6-8 Z:\BOTHELL\DATA\COA\1016-096WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH6.DOCX (8/20/2019 1:21 PM) CITY OF ASHLAND WATER MASTER PLAN CAPITAL IMPROVEMENT PLAN OM ,w m Gay StreeL and ,,,,,,I,,,,,, 6�man Cre6< Foad ` ,,,u Stations These two PRV stations are recommended for rezoning lower sections of the Crowson Zones 2 and 6 where significantly high pressures exist. This project could happen prior to extending Granite Zone 1 piping in East Main Street to these areas. Once the East Main Street piping is installed, these customers could be supplied mainly by the Granite Zone, and these PRV stations would be used for fire protection (supply fire from the Alsing Reservoir). This project is estimated to not be SDC eligible.

The Plan includes developing a cost -sharing methodology for future maintenance and improvements that will reflect each TAP partner city's original investment in the TAP system and future capacity needs. It is anticipated that an updated Intergovernmental Agreement will also result from the TAP Water Master Plan. Additionally, a revised TAP Water Master Plan is recommended every ten years. This project is assumed to be 10 percent SDC eligible. [, ,,,,,,, W f isk aridResHience Assessrnen „t. and E ii it ,,, � in ReF,)onse Recently adopted federal regulations under the Water Infrastructure Act require that the City perform a Risk and Resilience Assessment and Emergency Response Plan. This plan is required to identify all potential hazards to the City including natural hazards, human -caused threats, cyber- security threats, financial risks, etc. The plan also requires developing a mitigation plan to address all threats and develop an Emergency Response Plan. The regulations also include a short -time frame for completion of the Plan, and the City's plan will be due in FY21. This project is assumed to be 10 percent SDC eligible. A rezoning study is recommended to address the City's many locations experiencing significantly low and high pressures. The study may identify ways to use existing or planned pipe projects to create new sub -zones, identify potential new PRV stations, and evaluate the existing PRV settings in further detail than this WMP. This project is assumed to be 10 percent SDC eligible. RS.,,,, ,,,,,, m Water Master I" � n Updates The Oregon Drinking Water Program (DWP) requires that each water system have a current water master plan. A revised master plan is recommended every ten years to capture changes in demands.

Table 7-1 below summarizes total estimated costs by time period. Total costs are estimated at approximately $90.8 million in current dollars in this Water Master Plan (WMP) update. For the long-term period, there will likely be costs for treatment and storage, pump station, and operations and maintenance currently shown as zero dollars that will be identified in the next WMP update.

Included in the CIP are infrastructure projects that will benefit both existing and future City water customers; the financial analysis focuses on impact to existing ratepayers, as this is the group ultimately burdened with the cost; however, future users' cost share is discussed. To recoup the cost share to future users will require updating the City's water system development charges (SDCs), which is not part of this financial analysis. The chapter begins with a review of potential funding mechanisms to finance the CIP, and recommendations. 13otentoial �000000l ridinMeclo-ianisnns The City is eligible to apply for financial assistance from several State of Oregon and federal low-cost funding programs. The most applicable State funding programs for Ashland's CIP include the following: \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) 7-1 CHAPTER 7 CITY OF ASHLAND WATER SYSTEM PLAN wwmm11 �� J�� I,� �p u I,�� J�� '"u�� I nm I Oregon � onnlll�l n Innnnnigq moon M %�wW� im �� ait Ir' i "�" rid �nm '�nU� uuuwd� i � Ilu wam r W IW nimu nu n I01 non nnn� u�mu The most applicable program offered is the Safe Drinking Water Revolving Loan Fund (SDWSRF) program. This program is part of a national funding program spearheaded by the Environmental Protection Agency (EPA). Each year funds are disbursed to each state and states must capitalize the grants with additional funding, typically through the sales of state general obligation bonds. Loans repayments also add to the pool of available funding. Typical loan terms are 20 years with interest rates as low as 60 percent of market rates. Ineligible projects include dams, water rights, raw water reservoirs, projects primarily for fire protection, and projects primarily to serve future population growth. Water systems may submit a letter of interest any time online to begin the loan process. The program is managed by the Oregon Health Authority (OHA) and the loans are managed by the Oregon Infrastructure Finance Authority (IFA). Other programs managed by the OHA include the Drinking Water Source Protection Fund (DWSPF) and Sustainable Infrastructure Planning Projects (SIPP) programs. The DWSPF provides much smaller loans and grants for drinking water protection (up to $100,000 per project). The SIPP program is to fund small planning projects, such as water rate studies. Funding is a forgivable loan, up to $20,000 and may only be applied for every three years. Business Oregon, which runs the IFA, also oversees the Special Public Works Fund (SPWF) and Water Wastewater Financing (WWFP) programs. These funds provide loans up to $10 million with a payback period of up to 25 years. The WWFP program is specifically targeted to municipalities with a documented water quality compliance issue (or potential for one). The SPWF program is intended to support economic and community development in Oregon. Oregon r nnnilmnWater Resources nnim marcWuxgms I'll: Water project grants and loans, and feasibility grants, are available for water conservation storage and reuse. A cost share of 25 percent is required for this funding program which is available year-round. This funding source is targeted to projects that increase water use efficiency, develop new or expanded storage, allocate federally stored water, promote water conservation, and protect or restore stream flows. mw nmmn r n � �m p rm� i" nmm�� f noun �°� �ronm u � m m.y Quah`ty n Certain water infrastructure projects may qualify for funding through the Oregon Department of Environmental Quality (DEQ). The majority of this funding comes from the federal government and is supplemented by the State of Oregon. Projects may fit into 'nonpoint' and point source projects that prevent or mitigate water pollution and protect water sources. Planning and construction loans are available.

This is a grant -only program and it is competitive; water 7-2 \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) CITY OF ASHLAND WATER SYSTEM PLAN CAPITAL IMPROVEMENT PLAN infrastructure projects compete with other infrastructure projects (roads, bridges for example) for funding. The maximum grant amount is $3 million. The program is managed by the Oregon Business Development Commission (OBDC) and the grants are managed by the IFA. Federal funding programs may also be applicable for water infrastructure in Ashland; for example, the US Economic Development Administration has public works grants available as well as the Bureau of Reclamation (WaterSMART), and funding specific for environmental improvements are available from the US Environmental Protection Agency; these funding opportunities almost always require matching funds. Federal funding possibilities for projects can be researched at grants.gov. In addition to the above State and federal financing programs, the City can issue bonds to finance projects that cannot be funded with available water rates, SDCs, and water fund cash reserves. Usually, cities finance improvements with the sale of general obligation bonds or revenue bonds. The primary difference between these two types of bonds is that general obligation bonds are backed by the full faith and credit of the city, meaning any discretionary revenues can be used to service debt, whereas revenue bonds are repayable solely by the water enterprise fund. There are advantages and disadvantages to each type of bond; of note, revenue bonds do not require voter approval (general obligation bonds do). Another type of financing often used is formation of a local improvement district (LID). An LID only provides funding for a project of benefit to a specific geographic area; the beneficiaries of the improvements pay assessments to either cash fund or make debt service payments for the infrastructure improvements. C�11'��) 11'..o:'Unding 1��'-"Ian I'lecomirnendatiolols The financing plan that is recommended and presented in this chapter, based on the assumed need to complete all of the facilities in the CIP in the estimated timeframe they are needed, is to use cash (pay-as-you-go) as much as possible, followed by low cost financing. The largest single project cost is for the new water treatment plant. Table 7-2 on the next page shows the City has already secured an SRF loan and grant for $14.81 million of the total cost. The remaining cost will be funded using $6.0 million from cash reserves, and $11.19 million City -issued bonds. Over the next 10 years the total estimated cost of the CIP is $58.50 million. This cost estimate inflates the WMP CIP costs, which are expressed in current dollars. The financing plan presented in this chapter assumes that the City sells $29.07 million in general obligation or revenue bonds (of which $11.19 million is for the water treatment plant as shown in Table 7-2). The City may be able to take advantage of lower cost options including the Oregon IFA to finance some of the projects; this should be pursued to potentially reduce financing costs. Of the total remaining cost, the financing plan assumes that $14.52 million of cash is used, a $1.30 million loan from the DEQ (which has already been secured) is used to line the canal, the remaining SRF loan of $12.58 million is used up ($1.20 million has already been spent), and $1.03 million in SRF principal forgiveness (grant) is used. \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) 7-3 2W CHAPTER 7 CITY OF ASHLAND WATER SYSTEM PLAN Table 7-2 Summary of Water Treatment Plant Funding Customer Cost Allocation Item Existing Future Total Total Estimated WTP Cost Treatment Plant - SRF Funded Total WTP Funded by SRF Forgivable Loan Amount Repayable Loan with SRF Estimated Interest over Construction Period Annual Debt Service [1] Total Payments Principal Interest Treatment Plant - City Bond Funded Remaining WTP Cost Cash Funded Bond -Funded Remaining WTP Cost Annual Debt Service [1] Total Payments Principal Interest TOTAL WTP ANNUAL DEBT SERVICE $28,8021677 $3,200,297 $32,002,974 $13,3301679 $1,481,187 $14,811,865 $927,000 $103,000 $1,030,000 $12,403,679 $1,378,187 $13,781,865 $222,026 $24,670 $246,695 $538,000 $59,800 $597,700 $17,931,000 $13,781,865 $4,149,135 $15, 4 71, 9 9 8 $1, 719,111 $17,191,10 9 $5,4001000 $600,000 $61000,000 $10,071,998 $1,119,111 $11,191,109 $774,300 $86,000 $860,300 $17,206,000 $11,191,109 $6,014,891 $1,312,300 $145,800 $1,458,000 Source: City of Ashland.

Infrastructure that supports both customer groups has costs allocated between existing users and new growth according to the approximate percentage of capacity estimated to be utilized by each group. Detailed tables listing the infrastructure projects and cost allocation are provided in Appendix 6A Tables CIP-0 through CIP-4. The allocation of costs to future customers shown in Appendix 6A Table CIP-0 is based on benefit of facilities to certain growth areas within the City rather than overall growth. Although total growth in the City is projected at 10 percent of buildout figures, new growth is allocated 20 percent of the total estimated CIP costs because not all growth benefits equally from the new or upgraded infrastructure. Table 7-3 summarizes the infrastructure costs in current dollars by component of the water system. Almost 80 percent of costs are for the benefit of existing customers, with water treatment and storage and pipes comprising the greatest cost components. Table 7-3 Allocation of Water Capital Costs Cost Allocation to Customers Existing Future Total Recovery Rates SDCs Supply $10,636,868 $4,447,632 $15,084,500 Treatment & Storage $31,756,000 $4,244,000 $36,000,000 Pump Stations $2,261,100 $217,900 $2,479,000 Pipes $23,845,750 $9,627,750 $33,473,500 Operations & Maintenance $2,770,000 $35,000 $2,805,000 Recommended Studies $315,000 $635,000 $950,000 Total $71,5841718 $19,207,282 $90,792,000 Share of Total Costs 79% 21 % 100% Costs allocated to existing customers will be recovered through monthly water charges. Costs allocated to future customers will be recovered through water SDCs. Unlike rates, SDCs are one-time fees that are collected from new development to mitigate capital costs associated with improving the water system to accommodate greater water demand. Due to the timing of when certain improvements are needed and the timing of new growth there will likely be periods during which existing customers have to cover the costs of the full project costs, and SDC revenues will be received later. The water SDCs need to be updated to include facilities included in the 2019 WMP Update CIP. The financial analysis presented in this chapter assumes SDC revenues of $100,,000 per year. Actual water SDC revenue will fluctuate from year to year depending on the amount of new development and the level of the water SDCs. \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) 7-5 CHAPTER 7 CITY OF ASHLAND WATER SYSTEM PLAN Monthly fees paid by existing customers are also called water rates. Water rates pay for the annual revenue requirement of the water enterprise which includes typical operating costs (personnel, utilities, materials and services, for example), and debt service, as well as capital costs in the CIP. Figure 7-1 shows the historical components of the water enterprise fund expenses using year-end financial data from fiscal years 2014 through 2018. The largest cost components of the water system are personnel (39 percent of total expenses with benefits included), and central service (the water fund's share of general city functioning costs that are apportioned to all City departments). Figure 7-1 Water Enterprise Fund Annual Expenses A Franchise Tax 10% Supplies, Services Maintenance Water rates are paid monthly by about 9,000 customers, of which more than 90 percent are residential customers. Other customers include multi -family residential and other housing types (such as senior housing), as well as irrigation, industrial, commercial, and educational/government customers. 7-6 \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) CITY OF ASHLAND WATER SYSTEM PLAN CAPITAL IMPROVEMENT PLAN IIWI'IIIIIAU WN ��II�II� I'm � a o��,,�� mww� ri eve of uuuulM uuuuW� mimN uuuuW� illu The revenue requirement was projected for the next 10 years to account for anticipated CIP expenditures and increased annual operating costs using actual expenses from fiscal year ending 2018 as the base year.

Talent -Ashland -Phoenix (TAP) pipeline water deliveries costs are increased pursuant to the Medford Water Commission's projection through fiscal year 2023 and increased 3.5 percent annually each year thereafter. A summary of the projected revenue requirement is presented in Table 7-5; a supporting table is provided in Appendix 66 Table R-0. Underneath the projected revenue requirement is the estimated revenue collection from water rates. Revenue will continue to be greater than cost in fiscal year ending 2020 because of the need to raise cash for the water treatment plant. After this fiscal year, revenues from rates are projected to be lower than revenue needs; this is because the City will be drawing on accumulated cash from prior years to fund the CIP. \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) 7-7 2W CHAPTER 7 CITY OF ASHLAND WATER SYSTEM PLAN Table 7-5 Projected Revenue Requirement FY 2020 FY 2021 FY 2022 FY 2023 FY 2026 FY 2029 Year 1 2 3 4 7 10 Personnel $2,059,609 $2,193,483 $21336,060 $2,487,903 $31005,262 $3,630,205 Central Service $1,496,472 $1,541,366 $1,587,607 $11635,235 $1,786,865 $1,952,556 Other Operating Costs $1,889,384 $1,980,398 $2,075,726 $21176,601 $2,516,701 $2,921,710 Debt Service $1,008,246 $1,381,946 $11970,892 $3,466,302 $3,572,065 $3,642,196 Capital Outlay $540,000 $4,004,609 $21862,033 $555,236 $2,083,654 $743,752 Total Expenses $6,99%711 $11,101,802 $10,832,317 $10,321,278 $12,964,547 $12,890,420 Credits $234,587 $240,319 $246,223 $252,305 $273,001 $295,878 Revenue Requirement $6,759,124 $10,861,484 $10,586,095 $10,068,973 $12,691,546 $12,594,542 Est.

To avoid spikes in rate increases in future years, rates are projected to increase 4.00 percent each year for the next three years, 4.25 percent for the following two years, and 4.50 percent each year in the final four years. The WMP water demand projection includes demands with and without additional water conservation. The CIP was determined assuming no additional water conservation; because this financing plan is based on the estimated CIP costs, the revenue projection also does not incorporate additional water conservation; however, it should be noted that if additional water conservation is achieved, water rates may have to increase by more than 4.00-4.50 percent in future years. The calculated water rates are presented in Table 7-6 for the first five years of the projection.

In order to receive preferable financing terms and/or grant funding, the water bill needs to be at least $52.62 when using 7,500 gallons (or 1,000 cubic feet) in a month in Ashland (using the 2017 5-year ACS median household income figure for Ashland). Currently, the water bill is $61.73 for a household using 1,000 cubic feet in a month. With the first -year rate increase of 4.0 percent July 2020, the bill for 1,000 cubic feet of water would be $64.20, or 1.53 percent of median household income, as shown in Table 7-7, keeping the water bill within what is considered the threshold range of affordability in the industry. 7-10 \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) CITY OF ASHLAND WATER SYSTEM PLAN CAPITAL IMPROVEMENT PLAN Table 7-7 Impact of Rates on Household Affordability Item Monthly Ashland Median Household Income [1] $4,210 CURRENT Water Bill 3/4" using 1,000 cu. ft. $61.73 Water Bill as % of Ashland MHI 1.47% 2020-21 Water Bill 3/4" using 1,000 cu. ft. $64.20 Water Bill as % of Ashland MHI 1.53% Water Rates @ 2 % of MHI [2] $84.20 Source: US Census.

Minimize the need for borrowing or sale of bonds to fund water infrastructure by strategically timing commencement of projects and by raising SDCs and rates sufficiently in advance of the need to start commencement of projects. 2. Adjust the water SDCs as soon as possible to account for the revised CIP contained in this 2019 WMP Update. 3. Plan for 4.0 percent rate increases for the next three years, and 4.0 percent to 4.5 percent per year rate increases thereafter, depending on actual revenues realized and cost of service needs. 4. Review available cash in the water fund annually for planned capital expenditures and adjust SDCs and rates as necessary. 5. Continue to maintain reserves of at least 2 months of revenues and one year of debt service for unforeseen costs, revenue shortfalls due to drought, emergency repairs, and so forth. 7-12 \\RH2\DFS\BOTHELL\DATA\COA\1016-096 WMP 2016\10 REPORTS\FINAL DRAFT WMP\2019-WMPCH7.DOCX (8/20/2019 5:00 PM) I APPENDICES M7 H fL OL 0) 0 L) a) 0 _0 co > a)CO w co (n CD U) w (3) -0 0 = 0 a) ?! a) cn CO U) (3) 'n Z3 (n w CK3 0 c;-- (n c -0 (1) (1) > cu L) 2 (3) 0 0 D) a?
