REFERENCE(S): Presentation Irrigation System Capacity Evaluation Report II. ACTION REQUESTED OF COUNCIL / STAFF RECOMMENDATIONS: PRESENTATION ONLY - Presented by Paul Cross, PE, Executive Vice President and Ryan Withers, PE, Project Manager with RH2 Engineering, Inc. III. FISCAL IMPACT: NONE IV. HISTORY AND FACTS BRIEF: The City of Pasco (City) owns and operates an irrigation system that is independent of the City’s potable water system. The City’s Irrigation System Master Plan (Plan) was prepared in 2013, and although long-term improvements were evaluated and recommended within the Plan, the rapid growth experienced by the City since the completion of the 2013 Plan has exceeded previous growth projections and caused significant stress on the City’s irrigation system infrastructure during peak demand conditions. The City hired RH2 Engineering, Inc., (RH2) to perform a physical capacity analysis of the irrigation system based on existing demands and identify the existing system’s ability to serve imminent infill and growth within the system at locations identified by City Staff. The evaluation includes the model and analysis of the source capacity, conveyance system capacity and storage capacity in conjunction with current and future demands. Page 3 of 69 V. DISCUSSION: RH2 will present the findings and recommendations of this evaluation. This presentation brings the result of the analysis of the existing Irrigation system overall physical capacity. This is the first step. A next immediate step is identifying the improvements needed to address current pressure issues. Finally, further evaluation will be performed to determine available alternatives for meeting the irrigation needs beyond the City’s current serviceable area.

Withers, PE Composed by: Ryan M. Withers, PE Reviewed by: Paul R. Cross, PE Subject: Irrigation System Capacity Analysis Date: October 31, 2018 BACKGROUND The City of Pasco (City) owns and operates an irrigation system that is independent of the City’s potable water system. The City’s Irrigation System Master Plan (Plan) was prepared in 2013, and although long-term improvements were evaluated and recommended within the Plan, the rapid growth experienced by the City since the completion of the 2013 Plan has exceeded previous growth projections and caused significant stress on the City’s irrigation system infrastructure during peak demand conditions. The City requested that RH2 Engineering, Inc., (RH2) perform a physical capacity analysis of the irrigation system based on existing demands and identify the existing system’s ability to serve imminent infill and growth within the system at locations identified by the City. SOURCE CAPACITY The capacity of the City’s 11 existing wells and the Columbia River Intake facility is presented in the City’s Irrigation System Master Plan, and is reproduced in Table 1. However, the design point capacity of these facilities presented in an email from the City to RH2 on May 28, 2018, is slightly different than the capacity presented in the Plan, which is also shown in Table 1. Additionally, RH2 reviewed the City’s Supervisory Control and Data Acquisition (SCADA) system data for the 3-year period between 2015 and 2017 and identified the maximum sustained 10/31/2018 10/31/2018 Page 13 of 69 Technical Memorandum RE: Irrigation System Capacity Analysis October 31, 2018 Page 2 10/31/2018 1:39 PM Z:\RICHLAND\DATA\PSC\718-043\TM TO MSERRA RE IRRIGATION SYSTEM ANALYSIS.DOCX pumping rate of each facility. The maximum sustained pumping rate data also is shown in Table 1. The total source capacity of the design point capacities emailed to RH2 and the maximum sustained pumping rate based on the City’s 2015 to 2017 SCADA data is identical (17,750 gallons per minute (gpm)), and is approximately 6 percent less than the total source capacity presented in the City’s Plan. For the purposes of these analyses, 17,750 gpm is assumed to be the system’s total source capacity. Table 1: Irrigation System Source Capacity SYSTEM DEMANDS HISTORICAL DEMANDS The City’s 2015 to 2017 SCADA data was provided in 15-minute increments and was used to calculate the irrigation system’s recent historical demands. The system’s average day demand (ADD), maximum day demand (MDD), and peak hour demand (PHD) between 2015 and 2017 is shown in Table 2. Hourly data for June, July, and August of 2018 was provided to determine the 2018 MDD and PHD, which also is shown in Table 2. The 2018 total production and ADD is not included in Table 2 because the 2018 irrigation season was not complete during preparation of this technical memorandum.

The MDD occurred on Wednesday, August 1, 2018, and the PHD occurred between 5:00 AM and 6:00 AM on the same day. The system’s peaking factors are shown in Table 3. Peaking factors for 2018 are not included in Table 3 because the 2018 irrigation season had not concluded during preparation of this technical memorandum; and therefore, the ADD could not be calculated. Compared to the average peaking factors presented in the City’s Irrigation System Master Plan (Table 2-6), the MDD/ADD peaking factor of the system between 2015 to 2017 is approximately the same, but the PHD/MDD and PHD/ADD peaking factors of the system between 2015 to 2017 are significantly lower than the peaking factors presented in the City’s Plan, as shown in Table 3. Table 3: 2015 to 2017 System Peaking Factors IRRIGABLE ACREAGE The existing irrigation system provides service to approximately 1,975 irrigated acres as of September 2018. Based on the historical demands shown in Table 2, the average demand per irrigated acre served by the City’s system is calculated to range between approximately 2.95 and 3.60 acre-feet per year (AFY), as shown in Table 4. For comparison, the average AFY/acre based on the data presented in the City’s Plan is 3.88 AFY/acre, which is also shown in Table 4. Table 4: Acreage Served and Average SYSTEM CAPACITY SOURCE CAPACITY The evaluation of the combined capacity of the sources in this section is based on the criteria that they provide supply to the system at a rate that is equal to or greater than the MDD of the system. The system capacity is calculated based on the system’s existing supply capacity (shown in Table 1) and the historical MDD of the system (shown in Table 2).

The system’s firm capacity also is shown in Table 5, which considers the system’s largest source (the Columbia River Intake Facility) being unavailable to the system for any reason, such as due to an equipment failure or an irrigation main break. Based on the firm capacity of the system, the system has a supply deficiency of approximately 340 gpm. The surplus and deficient irrigable acreage available based on the total and firm source capacity, respectively, is shown in Table 5 and is based on the demand per acre served shown in Table 4. Table 5: Source Capacity Analysis STORAGE CAPACITY Storage is provided to the system by the Road 68 standpipe. The overflow elevation of this reservoir is approximately 659 feet, but the City currently operates the reservoir at a maximum elevation of 639 feet, which results in approximately 2.28 million gallons (MG) of water storage based on the maximum operating level of the reservoir. As identified in the City’s Irrigation System Master Plan, the City does not have established storage criteria for the irrigation system, and there are no regulatory guidelines to identify the storage needs of an irrigation system. For the purposes of these analyses, the irrigation system SCADA data was reviewed to determine the system’s consumptive volume that exceeds the firm source capacity of the system. The irrigation system’s SCADA data indicates that demands in excess of the firm source capacity occur for approximately 2 to 5 hours per day during peak demand days, generally occurring between approximately 4:00 AM and 8:00 AM. Chart 1 shows the system demand on the days in which the MDD and PHD occurred between 2015 and 2018 (the 2015, 2016, and 2018 MDD and PHD occurred on the same day; therefore, these days are shown only once in Chart 1).

The results indicate that on August 1, 2018, the day of the system’s historic PHD, the system demand exceeded the firm source capacity by 1,409,130 gallons. For the purposes of these analyses, this volume is assumed to be the storage requirement for the system, as shown in Table 6. Table 6: Storage Capacity Analysis Description Date Time Supply Exceeded Firm Capacity Volume Supplied in Excess of Firm Capacity (gallons) 2015 MDD and PHD 7/3/2015 4.25 hours 1,077,375 2016 MDD and PHD 6/29/2016 3.50 hours 734,580 2017 MDD 8/2/2017 3.00 hours 846,720 2017 PHD 8/7/2017 3.00 hours 906,660 2018 MDD and PHD 8/1/2018 4.50 hours 1,409,130 1,409,130 Total Available Storage 2,280,000 Dead Storage 1,599,871 Total Required Storage 1,409,130 (729,001) Total Surplus (or Deficient) Storage (200) acres Maximum Storage Requirement Total Surplus (or Deficient) Storage Page 17 of 69 Technical Memorandum RE: Irrigation System Capacity Analysis October 31, 2018 Page 6 10/31/2018 1:39 PM Z:\RICHLAND\DATA\PSC\718-043\TM TO MSERRA RE IRRIGATION SYSTEM ANALYSIS.DOCX Table 6 also presents the volume of dead storage in the existing system, which is the volume of the reservoir that cannot effectively be used because it is stored at an elevation that does not provide system pressures that meet the City’s 30 pounds per square inch (psi) minimum pressure requirements. This unusable storage occupies the lower portion of most ground-level reservoirs and is based on a maximum service elevation of 533.3 feet for the existing system (elevation identified based on the City’s hydraulic model, located near the intersection of Fenway Drive and Cleveland Lane). Based on the volumes of these storage components, the results of the existing storage evaluation is shown in Table 6, which indicate that the system currently has a storage deficiency of approximately 729,001 gallons. Based on the storage components evaluated in Table 6, the demand per acre served shown in Table 4, and an assumption that the shape of the system supply curve in the future is consistent with the shape of the curve shown in Chart 1 for August 1, 2018, (i.e., the time that supply will exceed the system firm capacity is 4.5 hours, and the ratio of the PHD to the average supply during this 4.5-hour period is the same), the storage deficiency shown in Table 6 correlates to approximately 200 irrigated acres of development. SYSTEM CAPACITY SUMMARY Based on the analyses in the preceding sections, the irrigation system has a surplus source capacity of 343 irrigated acres with all sources operational and a source capacity deficiency of 44 irrigated acres based on the system’s firm capacity, which assumes the City’s Columbia River Intake facility is unavailable to the system. The system also has an approximate deficiency of 200 irrigated acres of storage capacity. Based on these criteria, the storage capacity of the irrigation system is the physically limiting component of the system. If all sources are assumed to be available to the system, the surplus source capacity can be used to supplement the lack of sufficient storage available to the system, resulting in a net surplus of 143 irrigated acres of capacity. Without storage available to supply the PHD of development beyond the 200 acres that consumes the remaining storage capacity, the resulting surplus source capacity must be capable of supplying the PHD of additional development. Based on a PHD per developed acre of 13.49 gpm (3.88 AFY/acre shown in Table 4 multiplied by the PHD/ADD peaking factor of 2.90 shown in Table 3), 82 additional irrigated acres of development could be supported by the irrigation system’s sources if all sources are operational and available to the system, as shown in Table 7. Firm capacity is not shown in Table 7, because the system has a capacity deficiency based on individual source and storage components; therefore, neither component has capacity available to resolve the deficiency of the other component. Page 18 of 69 Technical Memorandum RE: Irrigation System Capacity Analysis October 31, 2018 Page 7 10/31/2018 1:39 PM Z:\RICHLAND\DATA\PSC\718-043\TM TO MSERRA RE IRRIGATION SYSTEM ANALYSIS.DOCX Table 7: Existing System Capacity Evaluation FUTURE SYSTEM CAPACITY The City’s irrigation system is anticipated to continue to grow based on infill and system expansion. Infill considers the development of areas near or adjacent to existing irrigation system infrastructure, and expansion considers the extension of the irrigation system to areas within the City’s Urban Growth Area that are undeveloped. For conservatism, the highest peaking factors from Tables 3 and 4 were used for the future system analyses, and are as follows. x MDD/ADD = 1.69 (based on 2017 demands) x PHD/ADD = 2.90 (based on the Irrigation System Master Plan) x Average AFY/acre = 3.88 (based on the Irrigation System Master Plan) Future Growth Figure 1 identifies potential infill areas that may be served in the future by the City’s irrigation system. Table 8 identifies each of these infill areas, the approximate gross acreage, the estimated acreage previously developed, the estimated acreage remaining to be developed, the estimated irrigated acreage, and the future demand of each area based on the peaking factors presented in the preceding section of this technical memorandum. Some of the areas identified in Figure 1 and Table 8 are completely developed in 2018. These areas are shown with zero acres remaining to be irrigated in Table 8.

Redevelopment plans for this area are understood to be currently under review by the City. Additionally, in December 2017, the City contracted with Murraysmith to analyze the ability of the irrigation system to serve the Washington State Department of Natural Resources (DNR) property identified as Location A in Figure 1. Timing of future developments is variable in nature; for the purposes of these analyses, two future growth scenarios were evaluated. 1. Locations A, F, G, H, J, and K are assumed to be the next developments and additional demands for the irrigation system. These locations comprise 84 irrigated acres, which exceeds the remaining system capacity identified in Table 7. 2. Remaining infill locations shown in Table 8 develop, and development occurs north of the intersection of Broadmoor Boulevard and Burns Road/Powerline Road until pressures are reduced to 30 psi at this location. SYSTEM ANALYSIS Hydraulic analyses were performed with the City’s irrigation system hydraulic model, provided by Murraysmith in Bentley WaterCAD format. RH2 updated the hydraulic model with recent irrigation main improvements based on Geographic Information System (GIS) data provided by the City. RH2 also scaled demands from the “2015 Demand” alternative, which was a future system alternative in the hydraulic model provided to RH2, to match the system’s peak historical MDD and PHD of 12,756 gpm and 17,669 gpm, respectively (in Table 2). The allocation of demands throughout the hydraulic model was not updated as part of the analyses presented in this technical memorandum. HYDRAULIC MODEL CALIBRATION Between June 28, 2018, and July 3, 2018, system pressures were measured at 12 unique locations throughout the irrigation system.

The results of the calibration analyses, shown in Table 9, indicate that pressures measured in the field are within 3 psi of the pressures calculated by the City’s hydraulic model based on the same facility setpoints and system demands. Table 9: Hydraulic Model Calibration Results As shown in Table 9, pressures at location Logger 1-5, which was located at the intersection of Powerline Road and Convention Drive, were measured as being below the City’s 30 psi minimum pressure criteria.

The resulting system pressures are shown in Figure 2, with the pressure for junctions of interest specifically identified in the figure. The minimum pressure provided during 2018 PHD conditions is 22 psi near the intersection of Wrigley Drive and Mariner Lane, which does not meet the City’s minimum pressure criteria of 30 psi. Pressures below 30 psi also are prevalent throughout the neighborhoods north of Burden Road and between Roads 60 and Road 68. Existing system PHD analyses were performed with all sources operational and operating at the flow rates presented in Table 1. FUTURE GROWTH SCENARIO 1 ANALYSIS Steady-state analyses were performed for the existing system based on the 2018 PHD, plus a PHD of 1,139 gpm (equivalent to 84 irrigated acres of development, estimated for Locations A, F, G, H, J, and K in Table 8). The resulting system pressures are shown in Figure 3, with the pressure for junctions of interest specifically identified in the figure. Minimum system pressures are reduced approximately 2 psi compared to existing pressures, with the minimum pressure provided during Scenario 1 PHD conditions being 21 psi near the intersection of Wrigley Drive and Mariner Lane. A minimum pressure of 36 psi is available along the northern property line of the DNR property (Location A in Figure 1), which is the highest elevation on the property. The minimum pressure provided under this scenario along Broadmoor Boulevard is 41 psi. Provided that sufficient irrigation main capacity is installed throughout these future developments, future growth Scenario 1 can be served by the existing system based on the assumptions identified in 10 20 30 40 50 60 70 80 Pressure (psi)Page 22 of 69 Technical Memorandum RE: Irrigation System Capacity Analysis October 31, 2018 Page 11 10/31/2018 1:39 PM Z:\RICHLAND\DATA\PSC\718-043\TM TO MSERRA RE IRRIGATION SYSTEM ANALYSIS.DOCX this scenario without significantly impacting the pressures provided throughout the existing system; however pressures below the City’s minimum pressure criteria of 30 psi will be provided for many customers during PHD conditions. Scenario 1 PHD analyses were performed with all existing sources operational and operating at the flow rates presented in Table 1. FUTURE GROWTH SCENARIO 2 ANALYSIS Steady-state analyses were performed for the existing system based on the 2018 PHD, plus the future development identified in future growth Scenario 1, plus a PHD of 707 gpm, which includes the additional 207 gpm PHD for infill areas C, D, E, and L, and 37 irrigated acres of development assumed to take place north of Powerline Road/Burns Road at the intersection with Broadmoor Boulevard. The resulting system pressures are shown in Figure 4, with the pressure for junctions of interest specifically identified in the figure. The existing system minimum pressures throughout the neighborhoods north of Burden Road and between Roads 60 and Road 68 are reduced by less than 1 psi compared to future growth Scenario 1 (approximately 1 to 2 psi compared to existing PHD conditions). Based on the existing transmission and distribution system, which includes 12-inch-diameter main in Broadmoor Boulevard, the pressure at the intersection of Powerline Road/Burns Road and Broadmoor Boulevard is 30 psi (at ground elevation 506 feet), as shown in Figure 4. Future development proposed at higher elevations near the intersection of Powerline Road/Burns Road and Broadmoor Boulevard will have pressures below the City’s 30 psi minimum pressure requirement. RECOMMENDATIONS The existing system is not capable of meeting the City’s 30 psi minimum pressure requirement for all customers during PHD conditions with all sources available to the system operating. As infill continues to occur throughout the system, service pressures are projected to reduce for existing customers, as identified in future growth Scenarios 1 and 2. Further, if any of the system’s sources are unable to be operated during PHD conditions, widespread areas of the system will receive pressures below the City’s 30 psi minimum pressure requirement. During PHD conditions, the City’s sources are supplying nearly 20,000 gpm to the system (19,969 gpm during the 2018 PHD, and 19,787 gpm during the 2017 PHD), which is significantly greater than the source capacities identified in Table 1. Therefore, the system’s supply pumps are likely operating “to the right” of the design point to meet the system’s PHD. As a result, the supply pumps are providing reduced total dynamic head to the system, causing the low pressure areas to be more widespread than the system likely was designed for. Additional source capacity is recommended to be evaluated to increase system pressures above the City’s 30 psi minimum pressure requirement, to allow the system’s supply pumps to operate at (or closer to) their design points, and to improve the reliability of the system such that a source can be offline for repair or maintenance without significantly impacting the level of service provided throughout the system. Approximately 3,000 gpm of additional source capacity is recommended for the irrigation system to accommodate the projected infill shown in Table 8, and resolve the existing storage capacity deficiency. Page 23 of 69 Technical Memorandum RE: Irrigation System Capacity Analysis October 31, 2018 Page 12 10/31/2018 1:39 PM Z:\RICHLAND\DATA\PSC\718-043\TM TO MSERRA RE IRRIGATION SYSTEM ANALYSIS.DOCX Some alternatives recommended for additional evaluation are as follows. x Verify the Columbia River Intake pumping capacity and limitations. Currently, the USBR/Harris Road Booster Pump Station (BPS) and Road 108 BPS have capacities that exceed the Columbia River Intake facility’s capacity. Acquire additional Columbia River water rights and evaluate the pump improvements necessary to match or exceed the USBR/Harris Road and Road 108 BPS capacities. x Acquire or adjust water rights to wells physically capable of providing additional capacity, including First Place, Sirocco, and Road 52 wells. x Refurbish or re-drill wells that have been rehabilitated previously, but that still sand or cavitate, including the Village and Northwest Commons wells. x Add additional flow meters and pressure gauges within the system to develop field pump curves for supply and BPS facilities in order to improve the understanding of system operations, and to incorporate the additional data into the City’s SCADA system. x Update the City’s GIS database with new irrigation system infrastructure as it is constructed and connected to the system. x Update the irrigation system hydraulic model with new infrastructure on a quarterly basis and perform additional evaluations of where capital improvements are needed to meet future growth and to address system deficiencies. Additional storage capacity is not anticipated to provide significant capacity increases for the irrigation system. A minimum of 729,000 gallons of usable storage (located above an elevation of approximately 603 feet) would be required to resolve the existing storage deficiency shown in Table 6, plus an approximate 350,000 gallons of additional usable storage to accommodate the 447 irrigable acres of infill estimated in Table 8 based on the total source capacity of the system if no source improvements are completed. Additional storage capacity would be required if the firm source capacity of the system is considered as the basis for the system capacity. Therefore, a minimum of 1,079,000 gallons of usable storage are required to resolve the system’s capacity deficiency based on the firm capacity of the existing sources. For reference, a 1,000 gpm difference between the source capacity and the system’s PHD equates to approximately 270,000 gallons of usable storage, which is equivalent to approximately 15 feet of storage within the existing Road 68 tank. be identified (is an existing well being rehabilitated or equipped with larger pumping equipment, or is a new well being drilled), that the additional supply rate provided by the additional source capacity be identified, and that the location of the additional storage be evaluated to determine the location that is most hydraulically beneficial to the system.

FISCAL IMPACT: Potential Utility Local Improvement District (ULID) – Phase 1 Proposed Capital Improvement Project (CIP) – Participation in Regional Lift Station IV. HISTORY AND FACTS BRIEF: The Northwest Area of Pasco has unprecedented potential for development with as much as 4,600 acres to consider. The City has been working with property owners and developers in the area to create preliminary plans for providing infrastructure to this area. With the proposed Urban Growth Area (UGA) set to expand, pushing the development boundaries further north and west of Pasco, the ability to provide for sewer in this area helps to meet the anticipated overall growth projections of 50,000 by 2040. The ability to serve this area with sanitary sewer has taken a huge leap forward with the design and construction award of the Harris Road Sewer Transmission Main Project, which is anticipated to be complete by the end of 2019. This vital connection to the existing sanitary sewer system will allow the development in this area to occur at a density considerate of the City's overall planning and land use objectives, is consistent with the requirements of the Growth Management Act, and City Council Goals.

V. DISCUSSION: The two main considerations for serving this area with sanitary sewer are a trunk sewer and a regional lift station along with associated gravity sewer network. (see Figure A) The first consideration is the possible Utility Local Improvement District (ULID) to construct a trunk sewer which is shown as the NW Area ULID – Phase 1 and Phase 2. Phase 1 has the potential to serve approximately 990 acres of the existing and future UGA area, with a future Phase 2 serving approximately 980 acres. The second consideration is the NW Area Regional Lift Station. This sanitary sewer lift station will be constructed in partnership with private development, namely Pahlisch Homes, and will serve an additional 810 acres. The anticipated time frame for the design and construction are as follows: Potential ULID Design - Summer 2019 Construction - 2020-2021 Proposed CIP - Participation in Regional Lift Station Design - Summer 2019 Construction - 2020 Page 31 of 69 DENT RD BUR NS RD ROAD 68SANDIFUR PKWY DESERET DRIVE (FUTURE) HARRIS RD ROAD 68 NCONVENTION DRIVEKOHLER RDCHAPEL HILL BLVDBROADMOOR BLVDROAD 90SHORELI NERDBYERS RDROAD 108CO L UM B I A R I V E R R D COLUMBIA R.

REFERENCE(S): Proposed Resolution Comprehensive Water System Plan Update Presentation Comprehensive Water System Plan Executive Summary II. ACTION REQUESTED OF COUNCIL / STAFF RECOMMENDATIONS: DISCUSSION III. FISCAL IMPACT: None IV. HISTORY AND FACTS BRIEF: City staff and the professional consulting firm of MurraySmith have coordinated efforts to complete an update to the Comprehensive Water System Plan (CWSP) in accordance with Washington State Department of Health (DOH) guidelines and in compliance with WAC 246-290-100. This CWSP provides a comprehensive update to the City’s last CWSP developed in 2009 and amended in 2010. The Plan has been reviewed and approved by DOH and is ready for adoption by the City Council. In conjunction with this Plan update the City's existing Water Use Efficiency (WUE) program was updated through a public forum process, per WAC 246-290-830. V. DISCUSSION: This CWSP presents the methodology and key findings for each evaluation required to Page 33 of 69 understand capacity of the existing system, the projected demands for the established planning horizons, and the performance criteria that describe the need for new infrastructure or improvements. The CWSP includes the following elements: Population and Demand Projection, System Analysis, Water Use Efficiency, Operations and Maintenance, Capital Improvements Plan and Financial Analysis. Standard planning horizons defined by DOH for projected demand and system analysis are 6-year and 20-year periods. The document includes also a 10-year period, in accordance with the approval cycle established for this Plan. The Water System Improvement Plan (also referred as Capital Improvement Plan or CIP in DOH guidelines) is a 20-year plan and addresses additional supply capacity, new storage tanks and pipe improvements. The 20-year list of improvements includes 29 projects and 8 studies, with an estimated total implementation cost of $48 million. This information will be refined further and included as appropriate into the Annual CIP Update later this year. The CWSP will also be incorporated as part of the Comprehensive Land Use Plan.

This Comprehensive Water System Plan (CWSP) identifies the need for capital investment and summarizes those investments. The recommendations contained within this CWSP were developed to identify and address deficiencies within the supply, pumping, reservoir, and piping systems, with the ultimate goal of compliance with Washington Department of Health’s (WDOH) regulations. At the time of development of this CWSP, the City’s population (2014) is 66,577, however the City’s Water Utility currently provides water service to about 70,770 people, which includes areas outside the City limits within Franklin County. ES.1.1 How This Plan Should Be Used This CWSP guides future system improvements, and should: • Be reviewed annually to prioritize and budget improvement projects. • Be updated every 10 years to address current conditions as required by WDOH. • Have the system mapping and hydraulic model updated regularly to reflect ongoing development and construction. • Have its specific project recommendations regarded as conceptual. The location, size, and timing of projects may change as additional site-specific details and potential alternatives are investigated and analyzed in the preliminary engineering phase of project design. • Have its cost estimates updated and refined with preliminary engineering and final project designs. ES.1.2 Purpose This CWSP provides a comprehensive update to the City’s last CWSP developed in 2009 and amended in 2010. The planning period for this CWSP is 2022, 2027, and 2036. This CWSP presents the sources of information, methodology and key findings for each evaluation required to understand the hydraulics in the existing system, the expected growth, the projected demands in each planning horizon, and the performance criteria that dictate whether new infrastructure is required. The proposed Capital Improvement Plan (CIP) is based on a number of technical evaluations with valuable input from the City’s staff. This document describes and provides justification for each project in the CIP, including cost opinions and implementation timeframe. The Page 38 of 69 15-1710.4084 Page ES-2 City of Pasco January 2019 Executive Summary Comprehensive Water System Plan CWSP does not include an analysis of the City’s water treatment plants (WTP), however it does provide the quantity and timing of supply required from those sources and a recommendation to complete a facility plan for the Butterfield WTP. The information presented in this CWSP and overall planning effort is subject to the quality of data available at this time. ES.1.3 Scope of Work The City selected Murraysmith, Inc. (Murraysmith) to update the 2009 Comprehensive Water System Plan. The CWSP is meant to act as a working document and tool for justifying improvements to the water system, while demonstrating the system’s ability to meet WDOH requirements. The scope of work for this CWSP included the following major tasks: • Evaluate the system performance under existing, 2022, 2027, and 2036 planning horizon conditions. • Projections of annual average and peak water supply demands. • Identification of existing and future water supply capacity. • Development of a system-wide and comprehensive steady state water system model. • Assessment of current and future drinking water quality regulations. • Identification of current and projected deficiencies related to water supply, pumping, piping, and storage. • Identify areas of deficient flow or pressure in the system through the 20-year planning period. • Evaluation of fire flow availability under current and future conditions. • Identification of discrete system improvements to correct current and anticipated deficiencies. • Development of a comprehensive listing of proposed improvements. • Summary of the financial program. • Overview of the operations and maintenance program. ES.1.4 Organization of the CWSP This CWSP is organized into nine sections with an executive summary, as described in Table ES-1. Detailed technical information and support documents are included in the appendices.

The irrigation system serves approximately 6,890 residential accounts and 39 commercial and public facility accounts. Providing a system for irrigation water separate from the drinking water utility allows the City’s customers to avoid using treated drinking water to irrigate. Where non-potable irrigation is available per customer potable water use is much lower on average as discussed in Section 3 - Population and Water Demand. ES.3 Water Service Area and Planning Information The City’s existing water service area is described in detail in Section 2 - Water Service Area and Planning Information. The current water system service area is approximately 19,160 acres. This includes acreage within the City limits and some unincorporated areas within Franklin County. The planning service area corresponds to the City’s 20-Year UGB (Urban Growth Boundary). The UGB was developed by the City through its Community Development Department, Planning Commission, and City Council with benefit of both citizen input and review, and has been approved by Franklin County. The planning service area is approximately 25,600 acres and is presented in Figure ES-2.

The 2014 population for the existing water service area was approximately 70,770. At this time, the City’s water system serves approximately 82 percent of the Franklin County population. The projected population for the 2036 City Water Service Area is 112,200, representing an increase of 70 percent from 2014. Table ES-3 shows the annual water production and average and maximum water usage for 2008-2014; this information was used to develop demands for system analysis.

In keeping with this commitment, the City’s Water Use Efficiency (WUE) program includes incentives that encourage wise water use and utilizes technologies and processes associated with City activities to improve water savings. ES.4.2 Future Demands System-wide future consumption projections were estimated as a part of the 2016 Regional Water Forecast and Conservation Plan (RWFCP). Future demands in the RWFCP were estimated using current patterns of water use and projected population. Table ES-4 presents the average and maximum day projections developed from the RWFCP.

For this planning horizon, the expected additional industrial demand is 0.6 mgd. • In 2027, the City’s water distribution system must have adequate capacity to serve a maximum day demand of 35.8 mgd, with a peak hour demand of 45.3 mgd, for a growth of 33 percent when compared to current demands (2015). For this planning horizon, the expected additional industrial demand is 1.0 mgd. • In 2036, the City’s water distribution system must have adequate capacity to serve a maximum day demand of 41.9 mgd, with a peak hour demand of 53.4 mgd, for a growth of 56 percent when compared to current demands (2015). For this planning horizon, the expected additional industrial demand is 3.1 mgd. Page 45 of 69 15-1710.4084 Page ES-9 City of Pasco January 2019 Executive Summary Comprehensive Water System Plan • Per-capita water usage and other indicators of water use in the system were evaluated on a system-wide level and do not include impacts from the separate irrigation system water use. Water usage developed is conservative since there is the potential that future potable demands may be lower. As recommended in ES.6 Capital Improvement Program a water demand study would help to improve future projections. ES.4.3 Water Rights Section 4 – Water Supply Summary presents the water rights evaluation for City of Pasco. The City currently holds surface water rights for 13,613.50 acre-ft of annual withdrawal and 20,149 gpm (29 mgd) of instantaneous withdrawal. The source for these rights is the Columbia River which are to be used for domestic potable purposes. The City also holds individual groundwater rights sourced by various wells for separate irrigation purposes. Water rights held by the City are anticipated to increase in the future pending the following: • Pending water rights transactions. • The outcome of applications for new water rights made to Ecology in 2011 and 2015. • Additional water rights available through subsequent distributions of water available under the regional Quad City Water Right (QCWR) permit. The QCWR permit identifies a total allocation of 178 cubic feet per second (cfs) (79,892 gpm) and 96,619 acre-feet, to be distributed amongst the Quad Cities (Pasco, Kennewick, Richland, and West Richland) in phases. • Additional future water rights acquisitions. ES.4.4 Water Quality and Protection The City’s complies with all drinking water regulations and has no water quality issues or violations. Both English and Spanish versions of the current Consumer Confidence Report which provides information on the water quality, are available on the City’s website. Section 4 – Water Supply Summary also presents the City of Pasco’s Watershed Control Program. ES.5 Water Distribution System Analysis The adequacy of the system’s various components was evaluated by comparing the existing capacity with the requirements dictated by the hydraulic criteria, for current and future demand conditions (2022 and 2036 planning horizons). The evaluation is subject to the low quality of data that is available at this time. Recommendations for the improvement data are defined in ES.6 Capital Improvement Program. The criteria are described in Section 5 – Design and Construction Standards. The hydraulic model was used to assess the system’s ability to convey flows under maximum day, peak hour, and fire flow conditions while maintaining minimum residual pressures. Additionally, supply, storage, and pumping capacity evaluations were performed to identify Page 46 of 69 15-1710.4084 Page ES-10 City of Pasco January 2019 Executive Summary Comprehensive Water System Plan the adequacy of those respective system components. The methodology and results of the system analysis are presented in Section 6 – Water Distribution System Analysis. Here are the main conclusions of the system analysis: • The results show that in general, the system has adequate capacity to provide for existing demands and to accommodate the 2022, 2027, and 2035 planning horizons. • The supply capacity evaluation shows that the system has enough “reliable” capacity as defined in Section 4 – Water Supply Summary to serve 2022 needs. The planned expansion of the West Pasco WTP will provide the additional supply (3.2 mgd and 9.0 mgd) that will be required by 2027 and 2036 respectively. • The storage capacity evaluation shows existing deficiencies in Zones 2 and 3 (combined deficiency of 5.8 MG). These deficiencies increase to 6.70 MG for 2022, 7.97 for 2027 and 9.05 MG for 2036. • The hydraulic analysis confirms the existing network is able to deliver water to meet peak hourly demand at the required pressure to customers, under existing and future conditions. • Fire flow availability was adequate in most of the system, with the exception of four locations under existing conditions and one location under future conditions. The associated improvement for these locations will be the upgrade or installation of short segments of pipe (less than 1,000 feet each). • The transmission system is adequate to serve existing and future needs, with only one deficiency on the 20-inch transmission line from West Pasco WTP to Broadmoor Pump Station during 2036 PHD conditions. • The City has partially developed infill areas with inadequate fire coverage and/or domestic water service area that have been identified. Specific improvements have not been defined at this time. As future infill development occurs the City will evaluate to determine required improvements required to improve fire flow and service. ES.6 Capital Improvement Program The results of these evaluations were used to develop improvement concepts for each deficient area. Once improvement strategies were defined, conceptual alignment/location, size, cost opinion and timeframe were determined for each project. This information is presented in Section 7 – Capital Improvement Program. Page 47 of 69 15-1710.4084 Page ES-11 City of Pasco January 2019 Executive Summary Comprehensive Water System Plan The following process was used to develop the capital improvement projects: • Improvements were sized to serve demands through 2036. • Pipe improvements utilize standard 8-, 12-, 16-, 20-, 24-, 30- and 36-inch diameters. No improvements under 8 inches in diameter were recommended. • Costs related to expanding the water treatment plant were developed by other consultants and provided by the City for inclusion in the CIP. The CIP includes 31 projects through 2036, of these 28 capital projects and six studies are recommended by 2027. Another three capital projects are recommended for the long-term (11-20 years). The total expected cost per project type and timeframe are summarized in Table ES-5. To serve the growth within the City’s planned future service area, concepts have been developed. The proposed future service area piping projects were developed with the intent of providing these areas with new pipes connecting to the existing system in different locations, creating loops to maintain redundancy and fire flow availability. Future service area projects are defined in Table ES-6, which provides an anticipated cost for expansion of the transmission system. The timing and funding of these projects is dependent on growth and development pressures with funding from the development community. Figure ES-3 presents the location of the proposed capital projects and the future service piping project concepts. The CWSP effort is an opportunity to improve and consolidate system information from different sources and to identify gaps or quality issues. Data quality or availability issues were identified throughout this CWSP; these include the following: • Limited pipe database with system connectivity as well as diameter, material, pressure zone, and age information. Continued development of water distribution pipe network geographical information system would allow the City to better management their water distribution system element information. • Characterization of the reduction in water demands for those customers that are served by separate irrigation coupled with spatial service meter demand information. Understanding of the location of use patterns will improve future demand projections and the results of future system evaluations. To aid the City in the development of the next CWSP, Table ES-7 summarizes the recommended data improvement studies and their cost. The cost ranges defined below are for planning purposes and will be further refined for each study as the City identifies the respective scopes of work.

Operations/maintenance/general administration/taxes; 2. Debt Service; 3. Capital Improvements. The results of the 2015 Rate Study identified that the current rate schedules were not adequate to fund the Water Utility for operations, capital and reserves and that a 5 percent yearly rate increase was required starting in 2016 through 2021. This rate increased was approved by the City Council on November 20, 2015, Ordinance 4252. Additionally, the revenue requirements summarized in Table 8-1, assume that there will be a 2.5 percent rate increase for 2022 and 0 percent for 2023-2027. A “Cost-of-Service” analysis was performed with the goal to maintain equity for the water and sewer utilities. A conservation based (inclining block) rate structure evaluation was completed for the City focusing on the single family residential class, since it represents 87 percent of the total City accounts. The current single family residential rate for the City is composed of a fixed meter charge differentiated by meter size and a uniform rate for all usage. The financial considerations are summarized in Section 8 – Financial Plan. ES.8 Operations and Maintenance Program Staff from the City’s Water Utility are responsible for the operation and maintenance of the treatment and distribution systems through the Water Treatment Plant Division and Water Distribution Division respectively. The Water Utility is structured and currently operated with 19 full-time equivalent employees (FTEs). The City maintains a Water Quality Page 53 of 69 15-1710.4084 Page ES-17 City of Pasco January 2019 Executive Summary Comprehensive Water System Plan Monitoring Program, Emergency Response Program, and Cross Connection Control Program to ensure a high-level service and safety to customers and staff. The review of staffing indicates that the City should at a minimum add 2 FTEs for the implementation of the uni-directional flushing program. The addition of 1 to 3 FTEs should be considered over the next 5 years based on system expansion. This includes West Pasco WTP upgrades to double capacity and require full time onsite staff and implementation of the meter AMI/AMR upgrade program. ES.9 Conclusion In general, the City’s main distribution and transmission system is adequate to provide required flows at adequate pressure under existing and future conditions. There are partially developed areas with inadequate fire service and/or domestic water service that need to be addressed as future infill development occurs. The treatment systems will need to be expanded to meet future peak demands which can be accommodated at the West Pasco WTP. The quality of the water is high without the need for additional treatment to address specific contaminants. The City does need to make an investment in the quality of their data in particular with respect to the continued development of a water system Geographic Information System (GIS). This information will be used to improve the quality of their hydraulic model in addition to tracking the age, material, size and condition of their piping. Improvements to the demand information relative to customer location, availability of non-potable irrigation, and peak usage should also be completed prior to future planning projects.

REFERENCE(S): Proposed Ordinance II. ACTION REQUESTED OF COUNCIL / STAFF RECOMMENDATIONS: ACTION: Discussion III. FISCAL IMPACT: N/A IV. HISTORY AND FACTS BRIEF: City Ordinances which are used by city officials or the public on an ongoing basis are frequently "codified" or placed in the Pasco Municipal Code for legal and convenient reference. For many years the City has done its own codification, providing access to the PMC primarily through bound volumes or the City's website. Last year the City contracted with Code Publishing to review the PMC, correct scrivener's errors and review for internal consistency and correct referencing. In addition Code Publishing has provided web publishing of the Code to improve navigation, searchability and other functionality. The revised, though not official, version of the Code is now online at the City's website. The Revised Code of Washington, RCW 35.21.500-570, provides requirements for cities to follow in codification of ordinances. The process involves a 1st reading, followed by a public hearing and then adoption after a 2nd reading. In order to comply with the RCW, staff recommends Council consider the ordinance providing for the re- codification at 1st reading on March 4 with a public hearing and 2nd reading on March 18. A delayed, but certain effective date of April 1st will give staff time to make certain that administration and enforcement actions are consistent with proper versions of the Page 61 of 69 Code. The proposed ordinance is attached. V.
