REFERENCE(S): 1. Fire Safety Inspection Program — Proposed Resolution June 4, 2014 Workshop Mtg.: 6/9/14 II. ACTION REQUESTED OF COUNCIL / STAFF RECOMMENDATIONS: 6/9: DISCUSSION III. FISCAL IMPACT: Estimated at $65,000. IV. HISTORY AND FACTS BRIEF: V A. The City of Pasco has not had a formal fire safety inspection program since 1987. During this time the City has experienced rapid commercial and industrial development. In the last rating by the Washington Survey and Rating Bureau (Bureau) in 2007, the City received 595 deficiency points out of a possible 650 in fire safety control. B. Pasco will receive a revised rating from the Bureau in 2015 or 2016. With the continued growth since the 2007 rating, the City could receive additional deficiency points and a re- classification. The Bureau and local commercial insurance vendors estimate that changes up or down from our current class 5 would result in an increase or decrease in the overall insurance premium between 5% and 10% depending on occupancy type, building construction, loss history and occupancy risk. C. Efforts already undertaken to improve the City's rating include automatic aid for building fires, training program improvements, ongoing regionalization of the communications system, smoke detector services, public fire safety educator certification and fire safety education programs, fire investigation certification program and juvenile fire setting intervention. The implementation of a Fire Safety Inspection Program will result in the highest chance to improve the City's rating from the Bureau. D. The Uniform Fire Code (UFC) is adopted by the City in conjunction with the adoption of the State Building Code, and through the UFC, the City has the authority to implement an Inspection Program and establish appropriate fees. E. City Council received a preliminary report on possible implementation of a Fire Safety Inspection Program at the January 13, 2014 Council Workshop. There was concurrence to move forward with establishing the program. DISCUSSION: A. To determine possibilities for a Fire Safety Inspection Program, the number of active City business licenses was inventoried. This resulted in a determination of 1,500 various types of commercial business licenses. These business licenses were broken down into the following categories: • Low Hazard Licenses (559) such as retail stores, beauty salons, business offices or small groceries without food preparation or fuel services... • Moderate - Hazard Licenses (730) such as restaurants, contractors with construction equipment and/or storage, used tire businesses, larger retail stores and dance halls or nightclubs... • High- Hazard Licenses (130) such as food processing and warehousing, automotive repair or body shops, welding, painting, roofing companies, materials storage, auto wrecking... • Others (49) such as schools, day cares, motels... 4(b) B. The Fire Safety Inspection Program is proposed to include a yearly inspection of all high hazard occupancies and a biennial inspection for all moderate hazard occupancies. Low hazard occupancies are not proposed for regular inspections. C. Apartments and multi - family units will be inspected through the existing Rental Inspection Program with revisions to the existing inspection checklist. The inspections will include adequacy and placement of fire extinguishers, door closures, automatic lighting and other fire related safety provisions. D. The Inspection Program will use an existing City building inspector. The resulting service gap with the construction inspection workload will be made up by the use of a contract building inspector. This will enable the Fire Safety Program to be initiated in- house. Any downtime in the construction inspection demand can be accommodated by deferring use of the contract inspector. Any downtime in the Fire Safety Program can be accommodated by using the existing building inspector for construction inspections. E. The construction inspector will be needed for the estimated 1200 hours that the existing building inspector will be devoting to the Fire Safety Program. In preliminary discussions with a private inspection service, this will result in a yearly cost for a contract inspector of approximately $65,000. This cost is proposed to be recovered through a fee for both initial fire inspections and re- inspections. A fee of $75 per inspection would recover all of the expected cost. A fee of $60 per inspection would recover $52,500 resulting in a City subsidy of $12,500 or about 20% of the Program costs. F. The Inspection Program for the High Hazard occupancies and a portion of Moderate Hazard occupancies can be initiated at the beginning of 2015 in conjunction with business license renewals. The remaining Moderate Hazard occupancies would be scheduled for inspections in 2016. G. The proposed resolution (Reference #1) would establish the Inspection Program. Once direction from Council oil the fee is received, staff will prepare an ordinance amending the existing Fee Schedule for Council action. RESOLUTION NO. A RESOLUTION ESTABLISHING A FIRE SAFETY INSPECTION PROGRAM FOR THE CITY OF PASCO. WHEREAS, the City is preparing for a Washington Survey and Rating Bureau rating process in 2015 or early 2016; and WHEREAS, adoption of the Uniform Fire Code provides the authority for the City to establish a Fire Safety Inspection Program and related fees; and WHEREAS, Implementation of a Fire Safety Inspection Program is likely to improve the City's Fire Rating, thereby minimizing increases or potentially realizing decreases in insurance rates; and WHEREAS, an effective Fire Safety Inspection Program is likely to reduce loss and injuries from fires and evacuations; and WHEREAS, a review of existing City business licenses indicates that there are approximately 130 High Hazard Occupancies and 730 Moderate Hazard Occupancies conducting business within Pasco; and WHEREAS, an effective Fire Safety Inspection Program will consist of yearly inspection of High Hazard Occupancies and biennial inspections of Moderate Hazard Occupancies; NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF PASCO: Section 1. The City Manager is hereby authorized and directed to establish the following Fire Safety Inspection Program effective July 1, 2015: In conjunction with the annual business license renewal cycle, the City will provide advance notice of the requirement for a fire safety inspection and a fire inspection checklist to High Hazard and Moderate Hazard occupancies. High Hazard occupancies will require an annual inspection and Moderate Hazard occupancies will require a biennial inspection. Apartments and multi - family units will have fire safety inspections conducted through the existing biennial rental inspection program. Section 2. The City Manager shall report annually to the City Council as to the cost and effectiveness of the Fire Safety Inspection Program. Passed by the City Council of the City of Pasco this _day of , 2014.

ACTION REQUESTED OF COUNCIL / STAFF RECOMMENDATIONS: 06/09: Discussion: 06/16: MOTION: I move to approve Resolution No. adopting the Irrigation System Master Plan. III. FISCAL IMPACT: IV. HISTORY AND FACTS BRIEF: A) On May 20, 2013, City Council approved a professional services agreement with MSA to complete a study of the City's water rights and a way to manage the available rights. The City owns and operates two water systems; one for domestic use and one for irrigation use. These systems are supplied by surface and ground water and include a surface water intake from the Columbia River, a system of 10 wells, with associated pumping and treatment equipment. B) The irrigation system has grown to include ten well sites, one river pump station, and a three million gallon standpipe, and now serves over 6,000 residential customers. In addition to the residential water users, the system also supplies irrigation for a soccer complex, five residential parks, two schools, and numerous landscaping areas maintained by the City. Service is provided from April through October. V. DISCUSSION: A) MSA has completed the Irrigation System Master Plan, including capital improvements for the irrigation system for the near and long term. B) Staff recommends Council's approval of the Irrigation System Master Plan by Resolution. 4(c) RESOLUTION NO. A RESOLUTION accepting the Irrigation System Master Plan prepared by MSA Associates. WHEREAS, the city presently provides irrigation water to more than 6,000 citizens and the city's population is expected to continue to grow; and WHEREAS, the city relies on approximately 932 acre feet of water from the Columbia River and 11 well sites for its irrigation water supply; and WHEREAS, withdrawals from the Columbia River are strictly regulated by the state in its effort to balance the needs of various user interests and it is, therefore, expected that additional withdrawals from the Columbia River will become increasingly difficult; and WHEREAS, the city acquired and has greatly expanded an irrigation system serving much of the Pasco plateau, thus partially mitigating the consumption of domestic raw water supply associated with urban growth on the plateau; and WHEREAS, the city recognizes the increasing need to preserve and conserve its irrigation supply as well as optimize the use and benefit of the wells it owns and operates; and WHEREAS, the city's consultant, MSA Associates, has studied the city's domestic and irrigation system supplies and has developed a management plan designed to optimize long -term use of the city's limited water supplies; NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF PASCO, WASHINGTON, DO RESOLVE AS FOLLOWS: Section 1. That the City Council hereby accepts the Irrigation System Master Plan prepared by MSA Associates, attached hereto as Exhibit A, to be used as a guide by staff and Council in making various decisions about the city's irrigation system.

(MSA) was authorized by the City of Pasco (City) to prepare this plan. Background The City of Pasco owns and operates an irrigation water utility that provides water to residential customers and a limited number of commercial customers. Providing a system for irrigation water separate from the potable water utility allows the City's customers to avoid using treated drinking water to irrigate. The City's existing irrigation system is supplied by water from 11 groundwater wells and water pumped from the Columbia River. The City acquired the first portions of the system in 2002 from a private irrigation utility. The system has grown considerably since that time. The City uses the irrigation system annually from April 1' to October 31'. The City has established the goal of developing a capital improvements plan for the irrigation system to ensure the continued delivery of economical irrigation water to City residents. Purpose The purpose of this plan is to provide a basis for identifying, analyzing, and planning capital improvements to the irrigation system. The study includes a hydraulic analysis of the existing system which compares the existing system's performance to analysis criteria in order to identify deficiencies and develop system improvements. A capital improvements plan is developed to assist in planning future projects. Included with this plan are conceptual level project cost estimates. The system's existing groundwater wells will also be evaluated through a tabletop review of existing data. The results of this review will be used to develop preliminary recommendations for improvements, further assessment, and rehabilitation work. Irrigation System Plan Overview This plan is organized by sections. Section 2 presents an inventory of the irrigation system and its components as they currently exist and operate. The City's irrigation water rights are also discussed in Section 2. Section 3 presents analysis criteria that form the basis for identifying deficiencies in system performance and planning improvements to the irrigation system. Section 3 also includes a description of the hydraulic model and the results of the modeling analysis work. Groundwater well condition assessments are also documented in this section. Section 4 presents recommendations for improvements to the system and to the groundwater wells, as well as recommended further study and planning work. 13- 1444.407 Page ES -1 Irrigation System Master Plan December 2013 Executive Summary City of Pasco r-\TA(_P,.s \13 \1444 -Pasco Water RS..

Parts of the irrigation system were first acquired by the City in 2002 from Kidwell Farms, Inc., a private irrigation utility owner. This utility was part of subdivisions built by private developers. Supply The City's irrigation system is supplied by groundwater produced from 11 wells located throughout the system and surface water pumped from the Columbia River. All sources of supply pump to the system's main service zone, referred to as the 639 pressure zone. Supply to lower zones is accomplished through the use of pressure - reducing stations. Groundwater Supplies The City's irrigation wells range between 135 and 245 feet deep and are completed in an unconfined alluvial aquifer consisting mainly of sand and gravel. The wells range between and 39 years old. Roughly half of the wells are constructed with perforated casing and the others with stainless steel, wire wrap well screen. The reported production capacities range between 450 and 2,500 gpm.

The storage tank sets the hydraulic grade for most of the City's system. The storage tank serves the 639 pressure zone by gravity, so the water is able to serve the other pressure zones at lower elevations through pressure - reducing stations. The City currently operates the tank below full at a volume of 2.28 million gallons (MG). Pressure Zones The irrigation system has six pressure zones. The zones are separated by pressure - reducing stations which allow zones with a higher hydraulic grade to supply zones having a lower hydraulic grade with water. Booster Pump Stations The City currently has one booster pump station in its irrigation system. This is the Road 108 Booster Pump Station located at the intersection of Road 108 and Crescent Road in the western portion of the irrigation service area. The design capacity of this station is 3,000 gpm. This station is used to boost water pumped from the Columbia River Intake Station to the 639 Pressure Zone. Another pump station is planned for construction in 2013. This station will be called the Harris Road Booster Pump Station and will be located on Harris Road near Interstate 182. This booster pump station has a design capacity of 3,125 gpm. The station will also pump water supplied by the Columbia River Intake Station to the distribution system. Dry Systems The City's irrigation system includes portions that are installed and ready for use, but not currently used. These systems are referred to as dry systems. The existing dry systems are shown in Figure ES -1. Table ES -4 shows a summary of the current dry systems.

The results are compared to . analysis criteria and form the basis for identifying deficiencies. Hydraulic Model The initial layout of the hydraulic model was completed by tracing pipes and junctions over the City's GIS data. Graphical and tabular data provided by the City were used to locate critical hydraulic elements such as the Road 68 Irrigation Tank, wells, pumps, and pressure - reducing stations. The demands presented in Section 2 were distributed throughout the 13- 1444.407 Page ES -7 Irrigation System Master Plan December 2013 Executive Summary City of Pasco KATAC_Pmia WU1 -Pa Water Reso urce SmdyN07 Plan PrepuetiontLxigation SVt --M-s PJ.\SWion0- Executive SumnmryAO. model using a nearest node method. The nearest node method assigns known demands with a known spatial distribution to the nearest node in the system. Model calibration was completed using data collected by the City's SCADA system. The system collects and logs information from the system every 30 to 60 minutes. Monitoring points on the system include well discharges, booster pump station discharges, and the storage tank. Analysis Criteria The analysis criteria used to evaluate the hydraulic performance of the irrigation system include minimum system pressures and maximum flow velocities. Any result not meeting these criteria is subject to further investigation and potential corrective action. Flow Velocities Pipes whose flow velocities exceed 5 feet per second (fps) under average day demand conditions are considered to have inadequate capacity. Pipe flow velocities are allowed to increase up to 8 fps during peak hour demand (PHD) conditions. Any pipes with flow velocities above 8 fps under PHD conditions are considered to have inadequate capacity. Irrigation System Pressures The City's pressure criteria at service connections are summarized below. These pressure criteria are based on industry standards, Uniform Plumbing Code requirements, and a review of landscape irrigation equipment water pressure requirements. 1. Each service connection should maintain a minimum water pressure of 30 pounds per square inch (psi) during all demand conditions. 2. No service connection should exceed a water pressure of 120 psi. Individual customers are responsible for reducing water pressures over 80 psi if they desire to do so. 3. During a failure of any part of the system, the maximum water pressure at customer meters will not exceed 150 psi. Model and Analysis Findings The calibrated model was used to simulate two scenarios: year 2012 conditions and an anticipated future demand condition. Modeling for the future condition included the City's existing dry systems, but did not include any new pipes or new developments. The results of each analysis are described below. Existing Conditions Existing conditions were modeled using 2012 PHD conditions. Two pipes in the system exceed the flow velocity criteria of 8 fps under PHD conditions. These pipes are 4 inches in diameter and located adjacent to the Sirocco Well discharge. All analysis criteria were 13- 1444.407 Page ES -8 Irrigation System Master Plan December 2013 Executive Summary City of Pasco K: \TAC_Proje 13 \1494 -Pasco WaaaaOw SnyA07 Pl FrapuationWngat SAtm Maeta FWa SWmO- Executive SlmamyAo= satisfied with regard to system pressures. The results are summarized below. A graphical summary of modeling results for the existing conditions scenario is shown in Figure ES -3. • The system does not experience pressures over 120 psi under any demand condition. In order to verify that maximum allowable pressures were not exceeded, a low - demand condition was used to approximate static conditions. • The system experiences pressures over 80 psi near discharges for wells and the Road 108 Booster Pump Station during high production. None of the locations which experience pressures between 80 and 120 psi serve customers. They are typically located on dedicated transmission mains and are caused by topography. • Low system pressures were not predicted by the model under this scenario during normal tank levels. If the storage tank water surface elevation reaches 600 feet above mean sea level (AMSL), the system begins to experience isolated low pressures. • No part of the system experiences pressures over 150 psi during a failure of pressure - reducing valves. It is possible that pumps could fail in such a manner as to cause high system pressures downstream of their discharges. Future Conditions The calibrated model was used to predict the hydraulic performance of the City's irrigation system under anticipated future conditions. The future condition assumptions are: • All of the City's current dry systems are connected and in use • All of the City's existing subdivisions are fully developed • All of the City's sources are producing the maximum allowed flows simultaneously These assumptions represent near -term conditions that could occur within the next two to five years. The actual timing of these conditions is dependent on a number of variables. Any changes in the following conditions would alter the analysis results: Expansion of the irrigation system service area beyond assumed service limits Additional sources of supply Changes in water rights High system pressures were found near the discharges of wells and pump stations as in the 2012 PHD scenario. No pipes that serve customers directly experienced high pressures. No low system pressures were found by the model. High flow velocities were found by the model at two locations: Near the discharge of the Sirocco Well as observed in the 2012 PHD scenario North of the intersection of Road 52 and Sandifur Parkway A graphical summary of modeling results for the future conditions scenario is shown in Figure ES -4. 13- 1444.407 Page ES -9 Irrigation System Master Plan December 2013 Executive Summary City of Pasco K\TAC Projects \13 \1444.Pasm Wazer omos SNdy \407Plan Prp tlon\h7ipdon Sya Maslen PlarMW!on0 -Ex ve Sun ..&m Q v.

The analysis concluded that the existing irrigation system reservoir has adequate capacity to meet projected storage needs as long as the water level in the tank is raised. Modeling confirmed that raising the water level does not have any adverse impacts on the distribution system. Well Condition Assessment A tabletop condition assessment of the City's groundwater supply wells was completed as part of this plan. The assessment consisted of gathering and analyzing available information. The objective of this analysis is to identify wells having apparent construction, performance, or water quality issues that may be limiting production with the purpose of developing a targeted approach at candidate wells to regain performance and optimize individual and combined system production. The results of the well condition assessments are summarized as follows: • Review of available information for the Desert Sunset, Sirocco, NW Commons, Island Estates, I -182, and Powerline Road wells indicated the presence of biofouling and incrustation which are possibly plugging screens and perforations. Significant accumulations of sediment or debris in the wells are also noted. • Observations indicated minor mineral and biological deposits within the First Place and Desert Estates wells. • Based on the information provided and relatively newer construction, the apparent conditions of the Road 52 and Linda Loviisa Wells are considered good. Recommendations Recommendations for improvements to wells, improvements to the irrigation system, and opportunities for further planning and study were developed as part of this report. The recommendations are separated into near -term improvements and long -term improvements. Near -term improvements are those which should be completed within the next one to five years. Long -term improvements should be completed in six to twenty years. The recommended capital improvement program totals approximately $800,000 for near- term improvements. The sum of recommended budget for long -term improvements is $6.87 million and does not include the $800,000 of near -term recommended investment. Table ES- 5 shows a summary of the recommended capital improvement budgets.

(MSA) was authorized by the City of Pasco (City) to prepare this plan. Background The City of Pasco owns and operates domestic and irrigation water utilities that provides water to residential customers and a limited number of commercial customers. Providing a system for irrigation water separate from the potable water utility allows the City's customers to avoid using treated drinking water to irrigate. The City's existing irrigation system is supplied by water from 11 groundwater wells and water pumped from the Columbia River. The City acquired the first portions of the system in 2002 from a private irrigation utility. The system has grown considerably since that time. The City uses the irrigation system annually from April Is` to October 31'. The City has established the goal of developing a capital improvements plan for the irrigation system to ensure the continued delivery of economical irrigation water to City residents. Purpose and Scope The purpose of this plan is to provide a basis for identifying, analyzing, and planning capital improvements to the irrigation system. The study includes a hydraulic analysis of the existing system which compares the existing system's performance to analysis criteria in order to identify deficiencies and develop system improvements. A capital improvements plan is developed to assist in planning future projects. Included with this plan are conceptual level project cost estimates. The system's existing groundwater wells will also be evaluated through a tabletop review of existing data. The results of this review will be used to develop preliminary recommendations for improvements, further assessment, and rehabilitation work. Irrigation System Plan Overview This plan is organized by sections. Section 2 presents an inventory of the irrigation system and its components as they currently exist and operate. The City's irrigation water rights are also discussed in Section 2. Section 3 presents analysis criteria that form the basis for identifying deficiencies in system performance and planning improvements to the irrigation system. Section 3 also includes a description of the hydraulic model and the results of the modeling analysis work. Groundwater well condition assessments are also documented in this section. Section 4 presents recommendations for improvements to the system and to the groundwater wells, as well as recommended further study and planning work. 13- 1444.407 Page 1 -1 Irrigation System Master Plan December 2013 Introduction City of Pasco K \TACPmjeas \13 \1444 -Pasco Waa Resolute Smdy\407Plan PrpaionWtiptbn Syuem MenaP \Smion1- Wmduaimfta :TION 2 SECTION 2 EXISTING SYSTEM Introduction This section describes the City's existing irrigation system's supply, storage, and distribution facilities. Water rights and historical production and demand data are presented. General operations are also discussed in this section. The information in this section forms the basis for building the hydraulic model and for developing the recommendations which result from analysis of the irrigation system. Existing Irrigation System The City's irrigation system piping is polyvinyl chloride (PVC), ductile iron (DI), and steel distribution pipes ranging from 3 inches to 24 inches in diameter. Table 2 -1 shows a summary of irrigation main sizes in the distribution system.

Parts of the irrigation system were first acquired by the City in 2002 from Kidwell Farms, Inc., a private irrigation utility owner. This utility was part of subdivisions built by private developers. The system has six pressure zones. The largest is the 639 pressure zone. All of the system's sources of supply and storage are located in this zone. The other five zones have a lower hydraulic grade line (HGL) and are supplied from the 639 pressure zone through pressure - reducing valves. Figure 2 -1 shows an overview of the existing system. Figure 2 -2 shows a hydraulic profile of the system. 13- 1444.407 Page 2 -1 Irrigation System Master Plan December 2013 Existing System City of Pasco KATAC_P j= \13 \1444 -POao WaWRaourca SWdyAVPlop Preps Whyipa nSy Maria PlanSww2- Existing Sys doc t m>a i I a,n�..a.�d..• 1 p. �..._.

All sources of supply pump to the system's main service zone, referred to as the 639 pressure zone. Supply to lower zones is accomplished through the use of pressure - reducing stations. Groundwater Supplies The City's irrigation wells range between 135 and 245 feet deep and are completed in an unconfined alluvial aquifer consisting mainly of sand and gravel. The wells range between 1 and 39 years old. Roughly half of the wells are constructed with perforated casing and the others with stainless steel, wire wrap well screen. The reported production capacities range between 450 and 2,500 gpm. Table 2 -2 summarizes the City's irrigation wells. Most of the City's irrigation wells are located on concrete pads and are open to the atmosphere with nearby electrical equipment in weatherproof enclosures. The Desert Sunset and Sirocco Wells are enclosed within buildings. The City has current capital improvement projects planned to construct new well houses around the First Place Well and the Linda Loviisa Well. The construction of these well houses is intended to prevent damage to equipment from exposure and reduce noise levels to nearby properties when the pumps are operating. None of the wells have backup power supply. Surface Water Supplies In addition to groundwater wells, the City uses water pumped from the Columbia River for irrigation supply. The river intake pump station conveys water directly to the Road 108 Booster Pump Station located on the west side of the system. The Road 108 Booster Pump Station pumps the irrigation water to the irrigation distribution system. Irrigation water pumped from the river is metered through a master meter at the Road 108 Booster Pump Station. Since there are no services between these two stations, all of the water pumped is metered prior to distribution and use. Water Rights Summary The City's current irrigation water rights are a combination of water rights issued by the Washington State Department of Ecology (DOE) and water rights which were given to the City by private parties. The City's annual irrigation water rights total 7,592.9 acre -ft. Table 2 -3 shows a summary of the City's existing irrigation water rights. Storage The irrigation system has one storage tank located near the intersection of Sandifur Parkway and Road 76. The storage tank sets the hydraulic grade for most of the City's system.

The irrigation system was formerly connected to the City's potable water distribution system through a backflow prevention device. The City completely removed the connection in 2006. Irrigation System Demands This section presents information on irrigation water production and demands. The City typically uses its irrigation system from April to October every year. Production is monitored and recorded by meters on each of the system's wells. Some large users are metered, but most connections to the system are not currently metered. Production Records Total system production is the sum of water produced by the irrigation system wells and water pumped from the Columbia River. Figure 2 -3 shows total system production from 2006 to 2012. As seen from the figure, system production has increased steadily from 2006 to 2012. The City performed two studies related to water use: one in 2001 and one in 2007. The study from 2001 includes information cited in this report on irrigation water use for public facilities and agriculture. The 2007 study contains more recent data on residential irrigation water usage which are also used in this report. Overall System Usage Historical production data was used to calculate overall system usage and peaking factors. The City has collected hourly data on all of its source meters and its storage tank for the past 13- 1444.407 Page 2 -8 Irrigation System Master Plan December 2013 Existing System City of Pasco K\TAC_Projec W \1444 -Paco We Resom Smdy\407 Plan Prepazatmo gam System Malta Plan\Seaion3- Existing Syamm.dom three years.

The City classifies connections to the system as either residential, billed on a flat fee basis, or connections for customers billed by the acre. These larger accounts are typically commercial irrigation customers and include public schools, parks, apartment complexes, and sports facilities. Table 2 -7 shows the number of connections to the system each year.

Since 2006, the production per residential connection to the system has remained relatively constant at 1,575 gallons per day per connection per year. Residential Demands The City does not meter water use on residential connections to the irrigation system. Residential irrigation use vanes widely across the City's service area and is dependent on economic factors, maturity of the landscaping, and whether or not the property is irrigated using domestic or irrigation water. The City studied residential water use patterns in a 2007 memorandum and determined that residential irrigation usage averages 3.18 acre -ft per gross acre per year or 5.31 acre -ft per irrigated acre per year. The memorandum is attached as Appendix B. Commercial Demands Commercial users of the City's irrigation system include public schools and the City of Pasco Department of Parks and Recreation. Irrigated facilities include a soccer complex, a track facility, a softball complex, and five residential City parks. The soccer complex is metered. Commercial irrigation usage varies according to the facility. City park use vaned from 19 gallons per square foot to 34 gallons per square foot. Water use at the athletic facilities averaged 40 gallons per square foot which is higher than the rest of the system. 13- 1444.407 Page 2 -10 Irrigation System Master Plan December 2013 Existing System City of Pasco KATAC_Projeras\13 \1444 -F.

Crops which are commonly grown at the three sites vary annually and include wheat, alfalfa, and potatoes. The pivots and land are not owned by the City. They include: • A single pivot located at Linda Loviisa Farms • A single pivot near the Northwest Commons Well • A single pivot north of Powerline Road near the Powerline Well All of the pivots are served directly by the system except for the pivot at the Northwest Commons Well. The Northwest Commons pivot may only run when the Northwest Commons Well is operating. Each pivot connection is metered. Pivot acreages were calculated by scaling aerial photo maps. An annual demand of 3.30 acre -ft per acre was used to estimate the annual water usage of each of these pivots. This estimated demand was calculated as part of a water usage study prepared by the City in 2001. Table 2 -8 shows a summary of the agricultural demands. Table 2 -8 Summary of Agricultural Demands General Operating Procedures City staff use a process referred to as staging to operate the irrigation system. In each stage, various wells or combinations of wells are selected for production. Each stage includes more pumps than the previous stage. When an additional pump is called to operate, it is referred to as a step up. When a pump is called to stop, it is called a step down. The system uses a delay between stepping up or stepping down to minimize pump cycling and prevent dramatic increases or decreases in pressure and flow. The order of pumps is chosen by the operator and varies on a regular schedule. The maximum number of stages is set by the operator and varies up to 11, which is the number of well pumps in the system. The system has the ability to operate manually or automatically via a master telemetry unit. Under automatic control, pumps are called to operate based on signals from pressure sensors within the system.

If a low pressure is registered at any of these sites and lasts for 30 seconds, a new pump is called to operate. This is called a low pressure step -up. When a pressure sensor sends a high pressure alarm that lasts for 10 seconds, the stage will step down. This is called a high pressure step -down. When the tank level is low, the stage is stepped up. This is referred to as a low tank level step -up. As long as the level remains low, additional pumps will be called to operate until the level rises above the low tank set point or the maximum stage is reached. If there is a high tank level signal, the stage is stepped down until the tank level falls below the high tank set point. Water Quality Water for the irrigation system is not treated. Available water quality data is attached in Appendix A. Agreements with Kidwell Farms, Inc. The City supplies irrigation water to three sites owned by Kidwell Farms, Inc. The three sites are the Northwest Commons subdivision, the Linda Loviisa Subdivision, and land leased from the Washington State Department of Natural Resources in Section 16, T -9 -N, R- 29-E. The City leases use of the Northwest Commons Well for an annual flat fee. The other pivots are connected to the system and a flat fee is paid to the City by Kidwell Farms for the connection. The fee varies by site and Kidwell Farms agrees to pay all maintenance and electrical costs associated with its use of the City facilities. Rate Schedule The City bills most of its customers based on a flat fee for connection to the irrigation system. Some large users are billed by the number of irrigated acres. Some users are billed by an irrigation unit which is defined as 5,000 square feet of irrigated area. The City's rate schedule and fees associated with the irrigation utility are summarized in Table 2 -9. Summary This section presented information on the existing irrigation system including sources of supply, storage facilities, and the distribution system. Current demand data and trends were documented. General operation of the system was explained and the irrigation rates charged to customers are shown. The next section will present the hydraulic analysis of the irrigation system and the well condition assessments.

The irrigation system analysis criteria include pressure, flow velocity, and storage criteria. A description of the analyses and associated findings are also presented. Irrigation System Analysis This section describes analysis of the irrigation system which uses a hydraulic model to simulate pressure and flow conditions in the system under several demand conditions. Model Layout The initial layout of the hydraulic model was completed by tracing pipes and junctions over the City's GIS data. Graphical and tabular data provided by the City were used to locate critical hydraulic elements such as the Road 68 Irrigation Tank, wells, pumps, and pressure reducing stations. Once initial layout was completed, the irrigation piping system was then skeletonized to simplify the layout and increase modeling efficiency. Skeletonization is a process that consolidates multiple real pipes into hydraulically equivalent single pipes. For this model, the majority of skeletonization converted dead ends to demands at a single node where the real pipe branches away from the system. Skeletonization was not performed on pipes larger than 8 inches in diameter. The modeling software's terrain extraction (TREX) program was used to apply elevations to the model nodes. The TREX program has the ability to apply elevations to hydraulic model nodes using a representation of a three - dimensional surface. The representation, usually contours, can be constructed using United States Geological Survey (USGS) data. The contours are superimposed on the model layout and the distance to the nearest two contours is used to interpolate the elevation of every node in the model. The final node elevations in the model are indicative of the surface elevation. The accuracy of the data and the final product is within 5 feet, which gives calculated pressures accurate to approximately 2 pounds per square inch (psi). Pipe Characteristics The hydraulic modeling software uses default modeling properties for common pipe materials. The City's irrigation system was modeled using the Hazen - Williams theory of 13- 1444.407 Page 3 -1 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco & %TAC ProjeclsUMIM -Pasw Waar Resources StudyW09 Plan Preen ni.Mfi igmioa System Mute PlanSendon 3 - Analysis and Fmdiayadnca pressurized flow. For PVC pipe, an initial C value of 150 was used. An initial value of 140 was used for steel pipe and 120 for ductile iron pipe. Water Demand Distribution The demands presented in Section 2 were distributed throughout the model using a nearest node method. The nearest node method assigns known demands with a known spatial distribution to the nearest node in the system. ArcGIS, a GIS software program, was used to identify irrigated parcels. The area and the geographic center of each parcel was calculated by the GIS program. This information was used to assign the geographic area of each parcel, in acres, to the nearest node in the model. To convert each node's area assignment to a water demand, the demands from Section 2 were used. The total irrigated area in 2012 was approximately 1,492 acres. The PHD from 2012 was approximately 17,529 gpm. The known point demands were subtracted from this total and assigned to the appropriate location in the model. Based on information received from prior water demand studies performed by the City, it was determined that the remaining total irrigation system demand could be distributed evenly across the irrigated area. This method gives an average demand of 11.75 gpm/acre which was then applied universally to all of the nodes in the hydraulic model. The modeled demand is within 1 percent of the demand measured by the City's SCADA system. Wells Wells were modeled using flow control valves attached to virtual reservoirs with a HGL higher than the rest of the City's system. The flow control valves were set to reflect the documented production rates of each well. Model Calibration Model calibration was completed using data collected by the City's SCADA system. The system collects and logs information from the system every 30 to 60 minutes. Monitoring points on the system include well discharges, booster pump station discharges, and the storage tank. Pressure and flow data were known at each pump discharge point within the system during the peak hour. The tank level was not known, so it was estimated using data from nearby points within the system. Flows from each of the wells were modeled using flow control valves. The initial simulation of the model produced hydraulic grade calculations at each well. These calculated hydraulic grades were then compared to the known hydraulic grades collected by the SCADA system and served as the primary calibration criteria. After several iterations, pipe roughness coefficients were universally lowered to a value of 130. All of the hydraulic grades were then within 4 percent of the target grades. Well calibrated models typically have discrepancies of 10 percent or less. Table 3 -1 shows the results of the calibration. 13- 1444.407 Page 3 -2 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco K \TAC PI.I m%13 \1444 -Paco WmerR..Smy\407Plan Prepaat.Urligelion System Mash Plan \genlion3 -Alu isand FiM,,doa Table 3 -1 Hydraulic Modeling Calibration Summary well Flow Target (gpm) Flow from Model m HGL Target HGL from Model Discrepancy Island Estates 590 590 610.5 612.47 0.3 Linda Loviisa 443 443 628.6 611.92 -2.7 I -182 1238 1,238 651.6 638.94 -1.9 First Place 1663 1,663 649.9 642.72 -1.1 Sirroco 1415 1,415 640.0 653.29 2.1 Desert Estates 491 491 634.4 617.16 -2.7 Desert Sunset 1418 1,418 628.2 618.46 -1.6 Northwest Commons 0 0 629.1 627.01 -0.3 Road 52 2125 2,125 644.4 634.34 -1.6 Powerline 1758 1,758 657.8 637.53 -3.1 Village Pasco Heights 936 936 622.6 614.52 -1.3 Analysis Criteria Once the physical layout and calibration of the model were completed, the model could be used to analyze flow velocities and pressures within the system. The analysis criteria used to evaluate the hydraulic performance of the irrigation system include minimum system pressures and maximum flow velocities. Any result not meeting these criteria is subject to further investigation and potential corrective action. Flow Velocities For this analysis, pipes whose flow velocities exceed 5 feet per second (fps) under average day demand conditions are considered to have inadequate capacity. Pipe flow velocities are allowed to increase up to 8 fps during PHD conditions. Any pipes with flow velocities above 8 fps under PHD conditions are considered to have inadequate capacity. These velocity limits reflect standard industry practices for acceptable flow velocities in pressurized piping systems. They are chosen to limit excessive head loss in the system. Irrigation System Pressures The City's pressure criteria at service connections are summarized below. These pressure criteria are based on industry standards, Uniform Plumbing Code requirements, and a review of landscape irrigation equipment water pressure requirements. Each service connection should maintain a minimum water pressure of 30 psi during all demand conditions. 13- 1444.407 Page 3 -3 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco KATAC_P ja \13 \1444 -Pasco Waeraaom SwdyW07 Plan Prepm&m*ftwion S,a Marta PW\Se wn3- Aiulyeis and Fwdinga.doa 2. No service connection should exceed a water pressure of 120 psi. Individual customers are responsible for reducing water pressures over 80 psi if they desire to do SO. 3. During a failure of any part of the system, the maximum water pressure at customer meters will not exceed 150 psi. System Storage This analysis uses standby storage recommendations provided by the Washington State Department of Health (DOH) for drinking water systems as water storage criteria because the City does not have established water storage criteria for its irrigation system. The DOH typically recommends that drinking water systems provide 150 minutes of water storage during peak demand conditions and that this storage be available to all customers at a minimum pressure of 30 psi. The City does not use the irrigation system to provide fire suppression, so no fire suppression storage is provided. Model and Analysis Findings The calibrated model was used to simulate two scenarios: 2012 conditions and an anticipated future demand condition. Modeling included the City's existing dry systems, but did not include any new pipes or new developments. The results of each analysis are described below. Existing Conditions Existing conditions were modeled using 2012 PHD conditions. These conditions are the same as those used for the calibration of the hydraulic model. Two pipes in the system exceed the flow velocity criteria of 8 fps under PHD conditions. These pipes are 4 inches in diameter and located adjacent to the Sirocco Well discharge. All analysis criteria were satisfied with regard to system pressures. The results are summarized below: • The system does not experience pressures over 120 psi under any demand condition. In order to verify that maximum allowable pressures were not exceeded, a low - demand condition was used to approximate static conditions. • The system experiences pressures over 80 psi near discharges for wells and the Road 108 Booster Pump Station during high production. None of the locations which experience pressures between 80 and 120 psi serve customers. They are typically located on dedicated transmission mains and are caused by topography. • Low system pressures were not predicted by the model under this scenario during normal tank levels. If the storage tank water surface elevation reaches 600 feet AMSL, the system begins to experience isolated low pressures. • No part of the system experiences pressures over 150 psi during a failure of pressure - reducing valves. It is possible that pumps could fail in such a manner as to cause high system pressures downstream of their discharges. 13- 1444.407 Page 3-4 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco K\TAC Projeala \13 \1444 - Pesco Water Resource Smdy`409 Plan PrepvatbnVrtigation System MasICPWVSection 3 - Awyrsis aM Fwdings.d«x A graphical summary of modeling results for the existing conditions scenario is shown in Figure 3 -1. Future Conditions The calibrated model was used to predict the hydraulic performance of the City's irrigation system under anticipated future conditions. The future condition assumptions are: • All of the City's current dry systems are connected and in use • All of the City's existing subdivisions are fully developed • All of the City's sources are producing the maximum allowed flows simultaneously These assumptions represent near -term conditions that could occur within the next two to five years. The actual timing of these conditions is dependent on a number of variables. Any changes in the following conditions would alter the analysis results: • Expansion of the irrigation system service area beyond assumed service limits • Additional sources of supply • Changes in water rights High system pressures were found near the discharges of wells and pump stations as in the 2012 PHD scenario. No pipes that serve customers directly experienced high pressures. No low system pressures were found by the model. High flow velocities were found by the model at two locations: Near the discharge of the Sirocco Well as observed in the 2012 PHD scenario North of the intersection of Road 52 and Sandifur Parkway A graphical summary of modeling results for the future conditions scenario is shown in Figure 3 -2. Storage The system storage was evaluated at projected peak hour demand conditions to determine whether or not enough storage is available in the system. The City currently operates the tank at a water level of 126.5 feet which corresponds to an elevation of 639 feet. At this level, the tank provides a total storage of 2.28 MG. The overflow of the tank is at elevation 660 feet. Water stored below elevation 597.5 feet is considered dead storage according to the storage criteria described above. The volume of dead storage in the tank is approximately 1.51 MG and the volume of active storage in the tank, as currently operated, is approximately 0.77 MG. The maximum possible average day demand was calculated by dividing the sum of the City's annual irrigation water rights by the days in service. This demand, 7,744 gpm, was used to 13- 1444.407 Page 3 -5 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco K1TAc_jws \13 \1444 -Pam Water Rao=w SNdy\407 Plan PrepantionWrisation SyI=Mata PUMSMion 3- Analyse ud Fmdin doa � B.1 „ it nig :kF 4�f.M-j 11 IN MEN oqw.; I cm BMW, Mo t na I :z ®R ID it T- 0— AV F 1 71 yes, bN.I A ..P; rP f 77t , , i- I .1 1] -T 14 1 j - A PT: .7, Wieser samess, Figum 3-2 CITY Of Flats, mistation System Master Plan HYDRAULIC MODELING RESULTS FOR FUTURE CONDITIONS A I , tatt� PT: .7, Wieser samess, calculate a projected peak hour demand of 22,419 gpm. A peak hour demand peaking factor of 2.895 was used. This demand would be met by a combination of the City's wells and storage. It was assumed that all of the City's sources would be pumping at the current instantaneous water right of 17,164 gpm. The tank would need to provide approximately 5,255 gpm for 150 minutes at a minimum pressure of 30 psi. Based on this analysis, the system requires approximately 788,250 gallons of storage for the projected peak demand, not including dead storage. Based on this analysis, the existing irrigation system reservoir has adequate capacity to meet these storage needs. Operations and Maintenance Problems The City experiences some operations and maintenance problems with the irrigation system which are described below. Northwest Commons Well Use The Northwest Commons well is plumbed so that it supplies the City's irrigation system and a nearby agricultural pivot simultaneously. Whenever the well is being operated, the pivot must also operate. Any water produced in excess of the pivot's requirements flows to the irrigation system. The City currently allows a private third party to use the well to operate the pivot, limiting the City's ability to use the well. The agreement under which this well is operated is attached as Appendix C. Freshwater Mussels Some parts of the irrigation system which convey water drawn from the Columbia River experience annual buildup of freshwater mussels in the piping. The most problematic area of the mussel infestation is in the piping between the Road 108 Booster Pump Station and the crossing under Interstate I -182. During the summer, high flows dislodge some mussels from the pipe walls which can cause operational problems such as plugging. Access to Pipes in Island Estates and Sunny Meadows The original irrigation system piping that was constructed by private developer Water, Inc. is located in the Island Estates and Sunny Meadows subdivisions. These pipes were installed in easements located in the less accessible alignments on private property. City operations staff may have difficulty accessing these areas for routine or emergency maintenance. Interstate Highway 182 Crossing Irrigation water supplied by pumps from the river intake station and the Road 108 Booster Pump Station is conveyed underneath Interstate Highway 182 to serve the majority of the City's irrigation system. The crossing ties into a pipe near Quadra Drive adjacent to the 13- 1444.407 Page 3 -8 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco K: \TACPrrxu \13 \1444 -Pa Wwer P.ao Shad 07Plan Prey nUmption System Mann Plan\S=Hon 3 -Awl is Fin Ws.doa interstate highway. Discussions with City staff indicate that a complete shutdown of the highway crossing is usually necessary to perform system maintenance and repairs in this area because of inadequate local isolation valving. Telemetry System and Communications According to discussions with City staff, the Powerline Well, Road 52 Well, and the Northwest Commons Well all rely on the same radio for communication with the system. If this single radio were to fail or be compromised, communication and control at all three sites would fail. City staff have indicated that the radio has experienced some irregular communication problems in the past. Data collected by the City's supervisory control and data acquisition (SCADA) system indicate that there is a problem with the remote level sensor in the Road 68 Irrigation Tank. Data received for the last several years does not include accurate or consistent readings on the tank water level. Well Condition Assessment A tabletop condition assessment of the City's groundwater supply wells was completed as part of this plan. The assessment consisted of gathering and analyzing available information. The objective of this analysis is to identify wells having apparent construction, performance, or water quality issues that may be limiting production with the purpose of developing a targeted approach at candidate wells to regain performance and optimize individual and combined system production. The results of this assessment are discussed below. Data Review and Gap Analysis The following information was provided by the City and was used in assessing the irrigation supply system: • Water Rights • Driller's well logs • Well construction records • Aquifer test results • Specific capacity • Well inspection reports • Well video surveys • Water quality data • Well usage information • General notes and observations gathered by City operations staff 13- 1444.407 Page 3 -9 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco KATAC_Proje \13 \1494 - Pasco Water Kesomces SsadyW PWPW=p n\lrrapon Sy=Mara Plao\$Mion 3 -AWl is Fwdings.doc All of the wells have some information available, but there are some data gaps that result in recommendations for further assessment. A tabular summary identifying the data available and the data gaps is presented in Table 3 -2. Observations and Analysis The results of the well condition assessments are summarized as follows: • Review of available information for the Desert Sunset, Sirocco, NW Commons, Island Estates, I -182, and Powerline Road wells indicated the presence ofbiofouling and incrustation which are possibly plugging screens and perforations. Significant accumulations of sediment or debris in the wells are also noted. • Observations indicated minor mineral and biological deposits within the First Place and Desert Estates wells. • Based on the information provided and relatively newer construction, the apparent conditions of the Road 52 and Linda Loviisa Wells are considered good. Table 3 -3 ranks the wells in terms of priority, potential for improvement, and overall condition assessment. The Desert Sunset Well received the highest priority ranking which means that it should be the first well to receive maintenance and rehabilitation. The Sirocco well has the highest potential for improvement which means that its capacity could be improved the most. The Desert Sunset Well received the highest condition assessment ranking indicating that it is in the worst overall condition. The overall assessment found that there are opportunities for well performance and yield improvements. The three highest - ranking wells in need of improvements are the Desert Sunset Well, the Sirocco Well, and the Northwest Commons Well. Table 3 -4 presents a summary of the well condition assessments. Summary This section presented an analysis of the City's irrigation system. The distribution system was analyzed using a hydraulic model. Current conditions and an anticipated future condition were modeled. Low pressures and high velocities, as defined by the analysis criteria, were noted. The irrigation system storage was analyzed for deficiencies. The condition of the City's groundwater supply wells was also assessed. The results of these analyses will be used in Section 4 to develop recommendations for improvements to the irrigation system. 13- 1444.407 Page 3 -10 Irrigation System Master Plan December 2013 Criteria, Analysis, and Findings City of Pasco K \TAC P jro UM1444 -Pas.

Recommendations for improvements to wells, improvements to the irrigation system, and opportunities for further planning and study are provided. Improvements Completed Since 2005 The City of Pasco has completed irrigation system improvements that were recommended as part of its 2005 I -182 Corridor Irrigation System Plan (2005 Plan). Table 4 -1 shows a summary of the improvements recommended in the 2005 Plan that have since been completed.

Construction of improvement IR 1.4 is 13- 1444.407 Page 4 -1 Irrigation System Master Plan December 2013 Recommendations City of Pasco K\rnc Pbjw\1A144 -Paco W%"K=ve4 sowrw07 Pwn PrapvawnWngazwn sn�rz aPw voo4- R«o�ww.do< no longer necessary because the City constructed an irrigation main along Sandifur Parkway to the tie -in point proposed by improvement IR 1.4. The main along Sandifur Parkway accomplishes the same hydraulic task as the main which had been proposed by IR 1.4. The City is currently completing design for a project proposing construction of a new river intake near the City's existing river intake station. The new intake would be used exclusively for drinking water and the old intake would be converted to irrigation use. Distribution System Improvements Recommended improvements to the distribution system include irrigation main extensions, replacement of undersized mains, looping improvements, isolation valve installation, and other minor improvements. Each is discussed below. Irrigation Main Improvements Irrigation main improvements include replacing undersized pipes to reduce head loss, extending existing mains, and looping mains to improve connectivity and reliability of the system. Recommended irrigation main projects are: • Extend arterial main on Powerline Road west to Road 90 • Extend arterial main on Powerline Road east to Road 52 • Extend arterial main on Sandifur Parkway east and south along Road 44 to tie in at Burden Boulevard • Extend distribution mains on Sahara Drive west to Road 44 • Replace small- diameter pipes on Sirocco Drive near Sirocco Well discharge with larger pipes • Extend existing main on Wrigley Drive from North Road 68 to Convention Drive. Completing this improvement requires right of way or easement acquisitions. Approximately 22,000 linear feet of new irrigation main are recommended for construction. The total estimated project cost for these improvement is approximately $2.77 million. An itemized tabulation of irrigation main projects and their associated costs is included later in this section. Interstate Highway 182 Crossing Isolation Valve Improvements It is possible to make complete shutdown of the Interstate Highway 182 crossing less frequent by installing isolation valves in the system nearby. This would allow operations staff to shut off portions of the line along Quadra Drive instead of the main crossing in order to make repairs. Repairs on the main crossing would still require the crossing to be shut down. 13- 1444.407 Page 4 -2 Irrigation System Master Plan December 2013 Recommendations City of Pasco K:\TAC_Proj.M\13U1 - P- -W-tra ourcee SIdIA07 4- A�om.doc Based on a review of available information, it is recommended that the City install two 12- inch diameter isolation valves near the highway crossing. For budgeting purposes, a project cost of $5,000 per valve has been allowed for a total project cost of $10,000. It is recommended that the installation of the valves be done between October 31 and April 1 when the irrigation system is not in use. Island Estates and Sunny Meadows Distribution Isolation Valve Improvements The Island Estates and Sunny Meadows subdivisions have irrigation systems that were installed in easements that run through the rear of residential lots. When one of these older mains breaks, City operations staff have difficulty getting access to residents' back yards to make repairs. Where possible, it is recommended that isolation valves be installed so that mains can be turned off from public right -of -way while repairs are made. It is recommended that the installation of the valves be done between October 31 and April 1 when the irrigation system is not in use. It is recommended that an estimated preliminary budget of $156,000 be provided to complete these improvements. This estimated budget is based on the installation of up to 52 valves at $3,000 per installation. The number of proposed isolation valves recommended is based on a review of the City's GIS data. It is further recommended that City staff identify final locations of the isolation valve improvements and confirm the final budget for this work. Northwest Commons Welland Pivot The Northwest Commons Well is currently plumbed to serve the nearby irrigation pivot and the City's irrigation system. It is recommended that the City install piping and valves near the well that allow the irrigation pivot to be supplied from the system instead of just the well. This new connection should be metered. The direct connection from the well to the pivot should be abandoned. This will allow the City to use the Northwest Commons well on its own schedule and allow the pivot owner to operate the pivot without operating the well. The estimated project cost for this recommendation is approximately $68,000. Telemetry Improvements Based on discussions with City staff, it is recommended that the City upgrade communication capacity along Powerline Road with the installation of a fiber optic line. The fiber optic line would serve as a more reliable means of communication from the central telemetry unit to the Powerline Well, Road 52 Well, and Northwest Commons Well. Having two ways to communicate to the wells makes the system more reliable as well. The estimated project cost for this recommendation is approximately $35,000. Source and Storage Improvements Recommendations for storage and irrigation well improvements are discussed below 13- 1444.407 Page 4 -3 Irrigation System Master Plan December 2013 Recommendations City of Pasco K:\TAC Pmjea l3 \1444.Pam WaWRoo Stodywal Plan PteP nWngation SpWmMasts Plan\Smion4- Reconn=Utbm.dom Storage The storage analysis presented in Section 3 found that the existing irrigation system reservoir has adequate storage capacity for the future conditions described if the reservoir is operated at a higher water level. It is also recommended that existing new water level sensing equipment be repaired or replaced to obtain more accurate water level readings. The estimated project cost for this recommendation is $10,000. Irrigation Well Improvements The results of the analysis presented in Section 3 were used to develop recommendations on irrigation well assessment, rehabilitation, replacement, and monitoring. A discussion of these recommendations is presented below. Well Assessment and Rehabilitation Plan The analysis presented in Section 3 was used to develop a well assessment and rehabilitation plan. The plan prioritizes candidate wells for further assessment and potential rehabilitation for the purposes of optimizing individual well performance and maintaining the value of the City's irrigation assets. This plan is developed to ensure that this asset remains in service for the long term at minimal operating costs. The main objective for rehabilitating a well is to restore or prevent losses in both production capacity and well efficiency. Conditions routinely found to contribute to declining well performance include incrustation, biofouling, physical plugging of formation or screen or both, and corrosion. These conditions could be caused by inherent characteristics of the aquifer, well design and construction, water quality, well operations, or combinations thereof. Rehabilitation techniques used to address these conditions in attempts to restore or recondition wells include: Mechanical methods such as brushing, surging, and airlift pumping to loosen and remove incrustation, organic material, and accumulated sediment Chemical treatments designed to dissolve and weaken encrusting minerals and biological slimes Impulse generation methods (e.g., Hydropuls®) that generate high- pressure pulses that loosen mineral and biological deposits in the well and adjacent formation. This technology is typically used in combination with other mechanical and /or chemical methods to increase its effectiveness A combination of mechanical, chemical, and impulse generation well rehabilitation methods are recommended for the following wells: • Desert Sunset • Sirocco 13- 1444.407 Page 44 Irrigation System Master Plan December 2013 Recommendations City of Pasco &ATAC_PT,l"U3n444 -P.. W.W Resources SWdy\4M Plan Prepavt .Vr lgazim System Mutes PUMSenion4 - Reconvnendazbnsdecx • Northwest Commons • Island Estates • I -182 • Powerline Road The recommended order of activities is as follows: 1. Conduct a one -hour specific capacity test to establish baseline conditions pre - rehabilitation and collect a groundwater quality sample for inorganic chemistry and bacterial assessment. 2. Remove pumping equipment and install rehabilitation equipment. 3. Brush and surge well to loosen buildup and airlift pump to remove debris. 4. Tremie dissolved chemical solution into the water column and agitate by surging to penetrate the formation and enhance the effectiveness of the treatment. 5. Apply impulse generation technology. 6. Remove the loosened debris by airlift pumping. 7. Conduct a video survey of the well, disinfect the well, and reinstall pumping equipment. 8. Conduct a one -hour specific capacity test to evaluate the effectiveness of the rehabilitation and assess the post - rehabilitation well performance. A combination of mechanical and chemical methods is recommended for the First Place and Desert Estate Wells to address the minor mineral and biological deposits observed. Activities to be performed would be those identified above, excluding the impulse generation efforts. Based on the information provided and relatively newer construction, the apparent conditions of the Road 52 and Linda Loviisa Wells are considered good and no rehabilitation efforts are recommended at this time. It is recommended that well video surveys be completed at these wells to verify existing conditions and monitoring each well's yield and drawdown. This work will establish baseline performance conditions and monitor for potential performance declines over time. It is recommended that no rehabilitation work be completed for the Village at Pasco Heights Well due to its age and poor condition. Based on an evaluation of the well rehabilitation is not likely to adequately address the significant incrustation, poor casing condition, and sanding conditions at this well. The recommended rehabilitation activities for each well are summarized in Table 4 -2. Well Data Acquisition Section 3 identified gaps in the available information concerning the City s existing irrigation water supply wells. A list of recommendations to fill those data gaps was developed and is presented in this section. Table 4 -3 shows a summary of the proposed data acquisition 13- 1444.407 Page 4 -5 Irrigation System Master Plan December 2013 Recommendations City of Pasco K \TAC_P ja W \1444 -Palm Waffa on SW YA0'1 Plan Pnyaarionllrtigatpn Slag Manta Plan \Smion4 - amommaMatiow.doa activities. It is assumed that the City has the resources necessary to complete the recommended activities, so a project cost was not developed for this work.

Conduct a specific capacity test. This test can be done in conjunction with Island Estates rehabilitation activities. Assess whether the yield can be increased at this well. A well field study should be performed to determine the optimal sizes and Linda Loviisa locations of new wells in the Linda Loviisa area. More information is resented below. Village of Pasco Heights Well Replacement It is recommended that a new well be drilled to replace the existing Village of Pasco Heights Well. To confirm the timing and need for this improvement, it is recommended that the well's yield and drawdown be monitored to assess changes in its performance over time and 13- 1444.407 Page 4 -6 Irrigation System Master Plan December 2013 Recommendations City of Pasco K:\TACPrejtaN13 \1444 -Pe Wawr om SmdyM7 Plan Prepmmiov\4tigation System Master Plan \S=iov4- Aecommevdazbrsdocx plan for replacement. The estimated project cost for a replacement well is approximately $173,000. A detailed cost summary is provided in Appendix D. Construction of New Irrigation Wells Based on the assessment presented in Section 3, up to six new wells could be necessary. These new irrigation wells would be a mixture of wells meant to replace some of the City's existing irrigation wells and wells improve the City's irrigation system capacity. For budgeting purposes, a project cost of approximately $616,000 per well has been developed. A detailed cost summary is available in Appendix D. The number of new irrigation wells that will be necessary will not be known until a well field study and data acquisition have been completed. The capital improvements program presented in this section assumes that all six wells will be necessary. Well Houses It is recommended that the City continue to improve its wells by enclosing them within well houses. Enclosures minimize potential damage to equipment from exposure and reduce noise levels. Well houses also improve the security of the well and add aesthetic value to the vicinity. The estimated project cost for this improvement is approximately $65,000 per well house. Well Performance Monitoring Program It is recommended that the City implement a monitoring program at all existing wells to track well performance and plan for periodic well maintenance, rehabilitation, and potential replacement. The recommended monitoring plan consists of bi- annual measurements of specific capacity from each well. The specific capacity measurements should be made prior to system start-up in the spring and following system shut -down in the fall. The process is described below: • Measure the static water level from a common measuring point during a period when the well has been idle. • Measure the pumping water level from the same measuring point after 30 and 60 minutes of pumping. • Maintain a constant pumping rate and record the flow rate at 30 and 60 minutes of pumping. • Calculate the specific capacity for each well. The specific capacity is the pumping rate divided by the amount of drawdown. Drawdown is calculated by subtracting the static water level from the pumping water level. The specific capacity measurements for each well should then be monitored over time to evaluate the need for maintenance and rehabilitation. Water levels should also be recorded 13- 1444,407 Page 4 -7 Irrigation System Master Plan December 2013 Recommendations City of Pasco KATAC_Projav \13 \1444 -Pasta Wau Resources SMdYAM Plan PM WnUrription System MasKr Ph"Wion4 -Rew= dawm.dom during periods when the well has been idle to assess whether apparent changes in specific capacity are actually related to well performance or groundwater level declines in the aquifer. Dry Systems It is recommended that the City begin using its existing dry systems. According to predictions based on hydraulic modeling, the City's existing irrigation system has the hydraulic capacity to support the new systems. This operational change does not have any associated capital cost as long as no new pipe is required to connect the dry systems to the existing system. Recommendations for Further Study and Planning During the course of this study, opportunities for further study that could improve planning efforts for the City's irrigation system were identified. This section presents those findings. Well Field Study It is recommended that a well field study be completed in order to determine the optimal locations and sizes of new irrigation wells in the Linda Loviisa area. These wells will increase the irrigation system capacity. A budget of $24,000 is recommended for this work. Freshwater Mussels It is recommended that the City conduct further investigation on the nature of the freshwater mussel infestation in the western portion of the system near the Road 108 Pump Station. Depending on the type of mussel, there may be federal or state regulations regarding acceptable ways to clear the pipes. The mussels should be identified and the extent of the infestation determined via television inspection or some other means. In the meantime, it is recommended that the City decrease pressure at the Road 108 Pump Station or limit its use. This may limit or halt the spread of the freshwater mussel colonization. A budget of $25,000 is recommended for this work. Rate Structure Study The City currently charges a flat rate to residential customers. Large customers are billed by irrigated acre. Some of its larger customers are served and billed according to undocumented verbal agreements. Industry experience has shown that the use of water under this rate structure is relatively uncontrolled. It is recommended that the City undertake a rate study and a financial review. The results of this work will assist the City in developing rates that ensure that the current level of service is maintained and that funds are available for capital projects and system growth. A budget of $25,000 is recommended for this work. 13- 1444.407 Page 4 -8 Irrigation System Master Plan December 2013 Recommendations City of Pasco K1TAC Pmjaa \13 \14J4 Puw Weer Resource SrudyWO] PW Preperaz "wnVrtiSetwn Syrian Mssta Plan\Senion4 - RewimnenEetunxdocx Irrigation System Master Plan Update As the City's irrigation system grows and additional water rights are acquired, the City should re- evaluate its capital improvements plan and check on the performance of the hydraulic system. This plan should be updated every five years or sooner to reflect major system expansions or changes as well as any significant changes in water rights. As part of this study it is recommended that the skeletonized hydraulic model be further developed to include all system piping. A budget of $30,000 is recommended for this work. Project Cost Estimates Project cost estimates were developed for all recommended irrigation system improvements. The project cost estimates include construction cost with a 10 percent contingency, sales tax, and a 35 percent allowance for administration, engineering, and legal services. The cost estimates developed are commensurate with a Class 4 cost estimate as defined by the American Association of Cost Engineers. The actual cost can vary from 30 percent under to 50 percent over the estimated cost. Appendix D includes data and detailed breakdowns of the project costs for the recommended system improvements. 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. For purposes of future cost estimate updating, the September 2013 ENR CCI for Seattle, Washington is 10147.96. Summary This section presented recommendations for capital improvements to the irrigation system and maintenance programs. These recommendations were based on analysis of the system as presented in Section 3. Tables 4 -4 and 4 -5 include tabulated summaries of all recommended improvements and their associated estimated project costs. The recommendations are separated into near-term improvements and long -term improvements. Near -term improvements are those which should be completed within the next one to five years. Long- term improvements should be completed in six to twenty years. Figure 4 -1 shows the City's irrigation system with recommended improvements highlighted and the dry systems operational. 13- 1444.407 Page 4 -9 Irrigation System Master Plan December 2013 Recommendations City of Pasco K\TAC_P je \13\1444 -Pssm WazecRp --Sm YW07 Plan PrepazationWngal 'wn Syuem Maeio PpnVSa9ion4 -Rxommw w..d..

MEMORANDUM CH2MHILL Residential Water Use Study TO: Bob Alberts, Public Works Director FROM: Tony Krutsch, Project Manager CH2MHILL DATE: August 3, 2007 INTRODUCTION This Residential Water Use Study looks at residential water consumption at various locations throughout the City of Pasco. Approximately 360 residential housing units were included in the study representing 16 neighborhoods. Neighborhoods were selected to represent a cross section of older and newer construction, with both separate irrigation systems, and those lots dependent on the City domestic water system as the source of supply for irrigation. This study represents an update of a Water Usage Study prepared by the City of Pasco in September 2001. In various locations throughout this technical memorandum, information from September 2001 Water Usage Study is quoted. Water records for each residential lot selected for this study were obtained from the City of Pasco Finance Department for the period of January 2005 through June 2007. After the water records were obtained and entered into a spreadsheet, the records were purged to remove inconsistent data that could have affected the analysis and evaluation. Unlike the September 2001 Water Usage Study, this evaluation is primarily based on the residential lot rather than population. CITY WATER USAGE Chart 1 identifies the average daily residential lot water usage for the 2 -year evaluation period for all neighborhoods included in this evaluation.

In older neighborhoods, winter usage averaged 237 gpd while in newer neighborhoods, winter usage averaged 155 gpd (average of 206 gpd for both older and newer neighborhoods). For those neighborhoods using the City domestic water system for residential lot irrigation, average daily domestic water usage was calculated at 883 gpd per unit, and the summer average daily water usage was calculated at 1,473 gpd per unit. The older Desert Plateau neighborhood had the highest summer average daily water usage at 2,939 gpd per unit. Older neighborhoods in central and east Pasco averaged 1,107 gpd per unit for the summer monthly period. Chart 2 identifies each of the 16 neighborhoods included in this evaluation and the average usage of City domestic water by neighborhood in ac -ft /month during the winter (Dec -Feb) and summer (June -Sept) periods.

For those neighborhoods utilizing a separate irrigation system for irrigation, the average monthly domestic water consumption was calculated at 0.0191 acre -ft per month and 0.2249 acre -ft per year. In neighborhoods relying on the City domestic water supply system for irrigation, the average monthly domestic water consumption was calculated at 0.0729 acre -feet per month and 0.8264 acre - feet per year. The older Desert Plateau neighborhood has the highest monthly average and annual average usage of domestic water at 0.1540 acre -feet per month, and 1.7836 acre -feet per year respectfully. The central and east Pasco neighborhoods, which rely on the City domestic water supply system for irrigation had a monthly average domestic water consumption of 0.0644 acre -feet per month, and an annual water consumption of 0.7229 acre -feet per year.

These differences are likely the results of selecting more residential units in each neighborhood in this Residential Water Use Study, and the use of different residents within each neighborhood in each evaluation. Desert Plateau is shown with 2 listings in Chart 8. Desert Plateau -1 is an older neighborhood which utilizes the City domestic water supply system for irrigation water, while Desert Plateau - 2 is a newer neighborhood with smaller lot size and fewer records available for analysis. One of the calculations presented in the September 2001 report was the estimated percentage of City water used indoors vs. outdoors for those neighborhoods where no separate irrigation supply system was available.

With an anticipated loss of up to 20 %, the application rate per lawn area would increase to 3.7 ac -ft or 27.7 gallons per sq -ft. In both the Desert Plateau -1 and Sun Willows neighborhoods, irrigation application rates are much higher than those anticipated by the Franklin Conservation District. The average application rate for irrigated lot area for the entire City of 5.31 ac -ft exceeds the anticipated application rate of 3.7 ac -ft (including losses) by approximately 44 %. WATER USE STUDY FINDINGS The following represents findings of this Residential Water Use Study and the evaluation of water consumption throughout the City of Pasco. 1. Residential Indoor Water Usage. In the older residential neighborhoods, daily domestic indoor water usage averaged 237 gallons per day (annual usage of 0.2655 acre -feet per year). For the new residential neighborhoods, daily domestic indoor water usage averaged 155 gallons per day (annual usage of 0.1736 acre -feet per year), or 53% less than older neighborhoods. For KENITID 08 DEMAND STUDY TECH MEMO.DOC COPYRIGHT 2013 BY CH2M HILL, INC. • COMPANY CONFIDENTIAL RESIDENTIAL WATER USE STUDY the new residential neighborhoods, it is highly likely that the plumbing fixtures and devices used have an improved efficiency over those in older neighborhoods. 2. Residential Outdoor Water Usage. For the 16 neighborhoods evaluated in this Residential Water Use Study, the volume of water consumed for domestic purposes was calculated at less than 50% of the total volume consumed for domestic plus irrigation. At the seven neighborhoods, utilizing the domestic water supply system for irrigation, the volume of water consumed for domestic purposes was calculated at about 30% of the total volume consumed for domestic plus irrigation (Over twice as much water was consumed by irrigation of a lot than was used for domestic purposes by each residential unit). In older residential areas (central and east Pasco), irrigation of the landscaped area of each lot was similar to that anticipated by the Franklin Conservation District (3.7 acre -ft per year) at 3.63 acre -ft per year (central) and 3.42 acre -ft per year (east) respectively. The central and east Pasco area residential units are of older construction, landscaping is considered to be mature and well established, and residents are generally considered to have moderate incomes. In newer residential areas (Sun Willows and Desert Plateau), irrigation of the landscaped area of each lot far exceeded the Franklin Conservation District anticipated average of 3.7 acre -ft per year. The Sun Willows neighborhood consists of relatively small landscaped areas (Average of 4,900 square feet) in a newly developed area. Residents are generally considered to have higher incomes. Irrigation application rates in the Sun Willows neighborhood were calculated at 5.89 acre -feet per year or nearly 60% greater than the Franklin Conservation District anticipated average. The Desert Plateau neighborhood evaluated for this study consists of residents with above average lot size, where income levels are generally considered to be high. Landscaping is generally 3 to 5 years old and irrigation application rates were calculated at 8.30 acre -feet per year. This application rate is 124% greater than the Franklin Conservation District anticipated average (3.7 acre -feet per year). Even if the actual irrigated area of lots within this Desert Plateau neighborhood were larger (by 25% to 10,000 square feet) than the average (8,100 square feet) calculated in the September 2001 Water Usage Study for Desert Plateau, the irrigation application rate to landscaped areas would be 6.72 acre -feet per acre or over 80% greater than the Franklin Conservation District anticipated average. APPLICATION TO WATER SYSTEM PLAN Based on this evaluation, the update of the City of Pasco Water System Plan will utilize the residential water consumption figures shown in Chart 11 for the projection of future domestic and irrigation supply demands for the existing and future residential neighborhoods throughout the Pasco Urban Growth Boundary.

Sincerely, Ahmad Qayoumi AQ /Jv Public Works Director �� l i Agreed to: t Tom Kidwell Date MASS b APPENDIX D PROJECT COST ESTIMATES Appendix D contains detailed cost estimating data used to determine project costs as presented in Section 4. Irrigation Mains Irrigation main project cost estimating data was prepared using bid tabulations from nearby irrigation districts. Some of the City of Pasco's recent bid tabulations were also used. The costs assume PVC irrigation pipe. Construction costs represented total estimated construction cost per linear foot (LF) of pipe and included sales tax. A 10 percent contingency was added to bid costs to calculate a construction subtotal. To calculate project costs, a 35 percent contingency was added to account for administrative, legal, and engineering costs. Table D -I summarizes irrigation main project costs.

Well rehabilitation costs are summarized in Table D -2 and are based on the following assumptions: • New pump and motor costs are not included • The City will conduct the specific capacity testing recommended at each well • The City will conduct well video surveys • Administrative, legal, and engineering costs for this project are estimated at 50 percent of the construction cost instead of 35 percent to account for additional on -site engineering representation associated with rehabilitation activities. Rehabilitation activities typically require more on -site representation than construction of new facilities. 13- 1444.407 D -1 Irrigation System Master Plan December 2013 Appendix D: Project Cost Estimates City f Pasco LMWc jectaVAIW - pascowuaresoun UWYMI Pi P mtiun\mguionryuanm =p4QWp dic %app MU d -Mjm cost aNnu &s ty Table D -2 Well Rehabilitation and Assessment Project Cost Summary Description Quantity Unit Unit Price Total Desert Sunset, Sirocco, Northwest Commons, Island Estates, 1-182, and Powerline Road Wells Mobilization and Demobilization 6 LS $1,500.00 $9,000.00 Disconnect, Remove, and Reinstall Existing Equipment 72 HR $350.00 $25,200.00 Specific capacity testing 12 HR $0.00 $0.00 Onsite Hourly Work to Perform Rehabilitation 96 HR $350.00 $33,600.00 Miscellaneous E ui ment and Chemicals 6 LS $1,500.00 $9,000.00 Video Survey 121 EA 1 $0.00 $0.00 Disinfection 61 EA 1 $1,000.00 $6,000.00 Wastewater Containment and Disposal 6 1 EA $2,500A0 $15,000.00 Subtotal $97,800.00 First Place and Desert Estates Wells Mobilization and Demobilization 2 LS $1,500.00 $3,000.00 Disconnect, Remove, and Reinstall Existing Equipment 24 HR $350.00 $8,400.00 Specific Capacity Testing 4 HR $0.00 $0.00 Onsite Hourly Work to Perform Rehabilitation 16 HR $350.00 $5,600.00 Miscellaneous Equipment and Chemicals 2 LS $1,000.00 $2,000.00 Video Survey' 4 EA $0.00 $0.00 Disinfection 2 EA $1,000.00 $2,000.00 Wastewater Containment and Disposal 2 EA $2,500.00 $5,000.00 Subtotal $26,000.00 Road 52 and Linda Loviisa Wells Specific Capacity Testing' 4 HR $0.00 $0.00 Video Survey' 2 EA $0.00 $0.00 Disinfection 21 EA 1 $1,000.00 $2,000.00 Subtotal $2,000.00 Subtotal $125,800 Construction Contingency (10 percent) $12,580 Sales Tax (8.6 percent) $11,900 Construction Subtotal $150,280 Administrative, Legal, and Engineering Costs (50 percene) $75,140 Rounded Estimated Project Cost $225,500 Notes 1.

Itemized costs are summarized in Table D -3 and are based on the following assumptions: • The well pump and motor in use at the existing Village of Pasco Heights Well are in good condition and can be reused in the new well. • Costs for infrastructure expansion for connection to existing water system are not included • No permitting costs are included • No cost for a well video survey is included since the City can perform the survey The total cost includes: • Aquifer and well performance testing (e.g., step -rate and constant -rate pumping tests) • Plumbness and alignment testing • Water quality analysis • 100 feet of 10 -inch diameter PVC discharge piping to connect to the existing irrigation system General New Irrigation Well Construction A general -use project cost was developed for use in budgeting construction of a new irrigation water supply well. The total estimated project cost is $616,000. Itemized costs are summarized in Table D -4. This estimated project cost can be used on a per -well basis and is based on the following generalized assumptions: • The total depth of the new well is 200 feet • The diameter of the well is 16 inches • The length of the stainless steel screen is 20 feet • The pump is a vertical turbine type pump with a 150 -HP motor equipped with a variable -speed drive • 500 feet of 10 -inch diameter PVC discharge piping will be needed to connect the well to the existing irrigation system • The City will perform well video surveys The total cost includes: • Aquifer and well performance testing (e.g., step -rate and constant -rate pumping tests) • Plumbness and alignment testing • Water quality analysis It is possible that individual well construction costs may vary from those presented here due to fluctuations factors such as depth, diameter, production rates, aquifer characteristics, and 13- 1444.407 D -3 Irrigation System Master Plan December 2013 Appendix D: Project Cost Estimates City of Pasco kAtwc ja \I3 \1444 -P WXa MOm "YW07 Pl Ptepa IMVmigmion SeWm m WPIMnAP icestap Wka - Mj=cos wtvmles.EOCx hydraulic conditions.

III. FISCAL IMPACT: None IV. HISTORY AND BRIEF FACTS: A) Each year, all Cities and Counties in the State are required to adopt an updated Six -Year Transportation Improvement Plan specifically for federal and state funded projects. For the City of Pasco, this plan has consisted of all projects including the annual overlays, street widening, and signal projects which are within the City limits. Larger projects such as the Lewis Street Overpass also have been shown. B) The proposed six -year program represents those projects that are anticipated to be needed within six years. Several projects will need to be coordinated with utility projects which could change the actual timing of the projects. Although this process of adopting a six -year plan is a state requirement, the Council will again review the projects in the annual Six -Year C.I.P. process and the budgeting process. While the worksheets presented by staff include a potential funding source, many of the projects listed will be dependent upon available funding. In addition, staff will be pursuing available grants from the various funding programs. Staff recommends the plan be presented at a public hearing on June 16, 2014, and that Council adopt the plan by resolution. 4(d) W Lei O � o � N � 1 � � p O p N � W C!3 C� p rte.

REFERENCE(S): H. Il. 100 V 1. Billing & Collection Processes - Proposed Ordinance June 2, 2014 Workshop Mtg.: 6/9/14 Regular Mtg.: 6/16/14 ACTION REQUESTED OF COUNCLUSTAFF RECOMMENDATIONS: 6/9: Discussion 6/16: MOTION: I move to adopt Ordinance No. , amending Pasco Municipal Code Title 3 establishing various fees, defining acceptance of credit cards and establishing procedures for miscellaneous billing and, further, authorize publication by summary only. FISCAL IMPACT: HISTORY AND FACTS BRIEF: A) The city bills for various types of services. The utility billing and collection rules are listed in Title 3 Chapter 200. Rent billing and collections processes are covered by individual contract. LID and cemetery billings and collections are covered by ordinance. Other types of services' (e.g. ambulance, abatements, inspections, false alarm response, etc.) billing and collection processes are not currently specified in the Pasco Municipal Code. Licenses, permits and impact fees are prepaid rather than a billed service and are therefore specifically excluded from this discussion. B) The city currently accepts credit cards for utility bills, cemetery bills, golf course activities and recreation activities. The attached ordinance would expand this acceptance to other billed services such as ambulance, fence replacement, back flow devices, engineering inspection, etc. It would continue to prohibit the use of credit cards to pay for non - billed charges such as permits, taxes, licenses, etc. DISCUSSION: A) Establish consistent due dates and collections fees for all billed services. Except as specified by contract or specific ordinance (e.g. rents, LIDS, etc.) billing and collection processes will be consistent with the utility billing and collection processes: Due when billed, $10 penalty at 28 days, $10 collection fee at 38 days, a $10 Pre - Collect collection agency notice at 45 days and turned over to outside collection agency at 75 days (5% collection agency fee). B) Expand credit card acceptance to include the remaining billed services. The use of credit cards for billed services is a way keep customer loan activities in the private sector. Examples of billed services are services for ambulance, cemetery, backflow devices, code enforcement, fence replacement, engineering inspections, false alarms, etc. Payment by credit card allows the customer to pay debts to the city in full, and immediately, when billed. The customer can then pay their debt to the credit card company (private lender) by setting the monthly payments at whatever they can afford. This is a cost effective alternative to the city establishing installment payment plans. I C) Formalize current policy of accepting credit cards for Recreational programs. Keeping the city out of the lending business is one reason to accept credit cards; the other is to promote certain activities or programs. The attached ordinance puts into code the current practice of promoting recreational (including golf course) activities by accepting credit cards and by waiving associated debit/credit card processing fees. D) Formalize current policy to disallow credit card (but allow debit card) use for prepaid (non - billed) charges. The processing fees for credit cards are higher than they are for debit cards because credit cards are paid over time and are a form of lending. Debit cards generally carry a lower processing cost because they transfer payment immediately and therefore are just to cover the one time transaction processing cost. Permitting, licensing and B &O tax processing activities are carried out primarily by the business sector and are normal business activities. The city does accept debit cards to provide business customers payment convenience. Unlike individuals that incur sudden, large bills (such as for Cemetery and Ambulance services), businesses typically have access to other types of credit (e.g. bank line of credit) that do not require the city to incur any financing costs. The code change maintains current practice for taxes, licenses and permit payments. E) Establish guidelines for installment billings: Installment plans should only be used for individuals and be short-term; an installment plan should not be authorized merely as a mechanism for customer convenience. All installment payment plans should be in writing in a form prescribed by the city and signed by both the customer and the Finance Manager. Installment payment plans would be available as follows: 1. For debts owed by individuals only. Installment plans are not available for debts owed by corporations, partnerships, businesses or other entity or associations; and 2. For debts as defined in 3.300.010 (which include such services as ambulance, cemetery, backfiow devices, fencing replacement, etc.); and 3. All installment payment plans must provide for payment in full within twelve months of the original bill date. Monthly payments are to be a minimum of $100. In cases of financial hardship, the applicant may request and the Finance Manager is authorized to set a reduced monthly payment of not less than $50 per month. Any installment plan should include a loan origination fee equal to the greater of 3% the amount owed or $10 and a per installment billing fee of $5. F) Existing agreements. Agreements entered into prior to the effective date would remain in place until paid in full or default (missed payment) occurs. If default occurs then the entire remaining amount becomes immediately due and payable. ORDINANCE NO. AN ORDINANCE of the City of Pasco, Washington, amending Title 3 "Revenue and Finance" establishing various fees, defining acceptance of credit cards and establishing procedures for miscellaneous billing. WHEREAS, the City provides a variety of services whereby the customer is billed for services rendered; and WHEREAS, some of those billing and collection processes are not currently included in municipal code; and WHEREAS, unifying billing and collection processes will provide a more efficient means of administering those systems and provide a more convenient and equitable system for the City's customers; NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF PASCO, WASHINGTON, DO ORDAIN AS FOLLOWS: Section 1.

Local Government Investment Pool — Transaction Authorization Form ACTION REQUESTED OF COUNCIL /STAFF RECOMMENDATIONS: 6/9: Discussion 6/16: MOTION: I move to adopt Resolution No. , naming Dunyele Mason as the "authorized individual" to authorize all amendments, changes or alterations to the Local Government Investment Pool Transaction Authorization Form and to acknowledge the terms and conditions of participation as outlined in the prospectus. FISCAL IMPACT: HISTORY AND FACTS BRIEF: A) The city utilizes the investment expertise of the State Treasurer's office and invests its excess cash into the Local Government Investment Pool (LGIP). In an effort to provide more clarity regarding how the LGIP operates and as a result of recently amended state WACs the LGIP has created and distributed a prospectus. B) As a condition of continued participation in the LGIP, the State Treasurer is requiring each investor to provide a copy of a Resolution that acknowledges the governing body has read, received and understands the prospectus as well as specifically designates, by name, the "authorized individual" that is authorized to create all amendments, changes and alterations to the Transaction Authorization Form (which controls who is allowed to move money and to designate which bank accounts money comes in and out of). Changes to the "authorized individual" must be made by a new resolution. DISCUSSION: C) The state is requesting a person's name rather than title to be specifically named by Resolution as the "authorized individual." As the Financial Services Manager is already bonded, staff recommends that Dunyele Mason be so named. 4(f) RESOLUTION NO. A RESOLUTION AUTHORIZING INVESTMENT OF MONIES IN THE LOCAL GOVERNMENT INVESTMENT POOL. WHEREAS, pursuant to Chapter 294, Laws of 1986, the Legislature created a trust fund to be known as the Public Funds Investment Account [commonly referred to as the Local Government Investment Pool (LGIP)] for the contribution and withdrawal of money by an authorized governmental entity for purposes of investment by the Office of the State Treasurer; and WHEREAS, from time to time it may be advantageous to the authorized governmental entity, the City of Pasco, the "governmental entity," to contribute funds available for investment in the LGIP; and WHEREAS, the investment strategy for the LGIP is set forth in its policies and procedures; and WHEREAS, any contributions or withdrawals to or from the LGIP made on behalf of the governmental entity shall be first duly authorized by the Pasco City Council, the "governing body" or any designee of the governing body pursuant to this resolution or a subsequent resolution; and WHEREAS the governmental entity will cause to be filed a certified copy of said resolution with the Office of the State Treasurer; and WHEREAS the governing body and any designee appointed by the governing body with authority to contribute or withdraw funds of the governmental entity has received and read a copy of the prospectus and understands the risks and limitations of investing in the LGIP; and WHEREAS, the governing body attests by the signature of its members that it is duly authorized and empowered to enter into this agreement, to direct the contribution or withdrawal of governmental entity monies, and to delegate certain authority to make adjustments to the incorporated transactional forms, to the individuals designated herein.

PASSED by the City Council of the City of Pasco, Washington, this 16th day of June, SIGNED in authentication of its passage this _ day of , 2014. Matt Watkins, Mayor ATTEST: Debra Clark, City Clerk Leland B. Kerr, City Attorney LOCAL GOVERNMENT INVESTMENT POOL Prospectus January 2014 James L. McIntire Washington State Treasurer Contents The LGIP 3 -4 wLei oovernment investment Pool —Money Market Fund 4 -9 Ill. Mdridgement 9 -10 I. The LGIP The Local Government Investment Pool (the "LGIP ") is an investment pool of public funds placed in the custody of the Office of the Washington State Treasurer (the "State Treasurer ") for investment and reinvestment as defined by RCW 43.250.020. The purpose of the LGIP is to allow eligible governmental entities to participate with the state in the investment of surplus public funds, in a manner that optimizes liquidity and return on such funds. In establishing the LGIP, the legislature recognized that not all eligible governmental entities are able to maximize the return on their temporary surplus funds, and therefore it provided a mechanism whereby they may, at their option, utilize the resources of the State Treasurer to maximize the potential of their surplus funds while ensuring the liquidity of those funds. The State Treasurer has established a sub -pool within the LGIP whose shares are offered by means of this Prospectus: The LGIP -Money Market Fund (the "LGIP -MMF" or the "Fund "). The State Treasurer has the authority to establish additional sub -pools in the future. The Fund offered in this Prospectus seeks to provide current income by investing in high - quality, short term money market instruments. These standards are specific to the Fund, as illustrated in the following table. The LGIP -MMF offers daily contributions and withdrawals. FUND SNAPSHOT The table below provides a summary comparison of the Fund's investment types and sensitivity to interest rate risk. This current snapshot can be expected to vary over time. LGIP -Money Market Fund Current Investments (as of November 1, 2013) Fees and Expenses Cash Bank Deposits US Treasury bills Repurchase agreements US Government aeencv 60 days Administrative Fee. The State Treasurer charges pool participants a fee representing administration and recovery costs associated with the operation of the Fund. The administrative fee accrues daily from pool participants' earnings prior to the earnings being posted to their account. The administrative fee will be paid monthly. In the event that there are no earnings, the administrative fee will be deducted from principal. The chart below illustrates the operating expenses of the LGIP -MMF for past years, expressed in basis points as a percentage of fund assets. Local Government Investment Pool -MMF Operating Expenses by Fiscal Year (in Basis Points) 2006 2007 2008 2009 2010 2011 2012 2013 Total Operating Expenses 1.12 0.96 0.84 a88 0.64 a81 0.68 0.87 (1 basis point = 0.01 %) Because most of the expenses of the LGIP -MMF are fixed costs, the fee (expressed as a percentage of fund assets) will be affected by: (i) the amount of operating expenses; and (ii) the assets of the LGIP -MMF. The table below shows how the fee (expressed as a percentage of fund assets) would change as the fund assets change, assuming an annual fund operating expenses amount of $800,000. Fund Assets $6.0 bn $8.0 bn $10.0 bn Total Operating Expenses (in Basis Points) 1.33 1.0 .80 Portfolio Turnover: The Fund does not pay a commission or fee when it buys or sells securities (or "turns over" its portfolio). However, debt securities often trade with a bid /ask spread. Consequently, a higher portfolio turnover rate may generate higher transaction costs that could affect the Fund's performance. II. Local Government Investment Pool - Money Market Fund Investment Objective The LGIP -MMF will seek to effectively maximize the yield while maintaining liquidity and a stable share price of $1. Principal Investment Strategies The LGIP -MMF will seek to invest primarily in high - quality, short term money market instruments. Typically, at least 55% of the Fund's assets will be invested in US government securities and repurchase agreements collateralized by those securities. The LGIP -MMF means a sub -pool of the LGIP whose investments will primarily be money market instruments. The LGIP -MMF will only invest in eligible investments permitted by state law. The LGIP -MMF will not be an SEC - registered money market fund and will not be required to follow SEC Rule 2a -7. Investments of the LGIP -MMF will conform to the LGIP Investment Policy, the most recent version of which will be posted on the LGIP website and will be available upon request. Principal Risks of Investing in the LGIP -Money Market Fund Counterporty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies. Interest Rate Risk. The LGIP -MMF's income may decline when interest rates fall. Because the Fund's income is based on short -term interest rates, which can fluctuate significantly over short periods, income risk is expected to be high. In addition, interest rate increases can cause the price of a debt security to decrease and even lead to a loss of principal. 4 Liquidity Risk. Liquidity risk is the risk that the Fund will experience significant net withdrawals of Fund shares at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss. Management Risk. Poor security selection or an ineffective investment strategy could cause the LGIP -MMF to underperform relevant benchmarks or other funds with a similar investment objective. Issuer Risk. The LGIP -MMF is subject to the risk that debt issuers and other counterparties may not honor their obligations. Changes in an issuer's credit rating (e.g., a rating downgrade) or the market's perception of an issuer's creditworthiness could also affect the value of the Fund's investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation. Also, a decline in the credit quality of an issuer can cause the price of a money market security to decrease. Securities Lending Risk and Reverse Repurchase Agreement Risk. The LGIP -MMF may engage in securities lending or in reverse repurchase agreements. Securities lending and reverse repurchase agreements involve the risk that the Fund may lose money because the borrower of the Fund's securities fails to return the securities in a timely manner or at all or the Fund's lending agent defaults on its obligations to indemnify the Fund, or such obligations prove unenforceable. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. Risks Associated with use of Amortized Cost. The use of amortized cost valuation means that the LGIP -MMF's share price may vary from its market value NAV per share. In the unlikely event that the State Treasurer were to determine that the extent of the deviation between the Fund's amortized cost per share and its market -based NAV per share may result in material dilution or other unfair results to shareholders, the State Treasurer may cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results. An investment in the LGIP -MMF is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of investments at $1 per share, pool participants could lose money by investing in the LGIP -MMF. There is no assurance that the LGIP -MMF will achieve its investment objective. Performance The following information is intended to address the risks of investing in the LGIP -MMF. The information illustrates changes in the performance of the LGIP -MMF's shares from year to year. Returns are based on past results and are not an indication of future performance. Updated performance information may be obtained on our website at www.tre. wa.gov or by calling the LGIP toll -free at 800- 331 -3284.

The State Treasurer may, in its sole discretion, allow for transactions of less than five thousand dollars. Valuing Shares The LGIP -MMF will be operated using a net asset value (NAV) calculation based on the amortized cost of all securities held such that the securities will be valued at their acquisition cost, plus accrued income, amortized daily. The Fund's NAV will be the value of a single share. NAV will normally be calculated as of the close of business of the NYSE, usually 4:00 p.m. Eastern time. If the NYSE is closed on a particular day, the Fund will be priced on the next day the NYSE is open. 5 NAV will not be calculated and the Fund will not process contributions and withdrawals submitted on days when the Fund is not open for business. The time at which shares are priced and until which contributions and withdrawals are accepted is specified below and may be changed as permitted by the State Treasurer. To the extent that the LGIP -MMF's assets are traded in other markets on days when the Fund is not open for business, the value of the Fund's assets may be affected on those days. In addition, trading in some of the Fund's assets may not occur on days when the Fund is open for business. Transaction Limitation The State Treasurer reserves the right at its sole discretion to set a minimum and /or maximum transaction amount from the LGIP -MMF and to limit the number of transactions, whether contribution, withdrawal, or transfer permitted in a day or any other given period of time. The State Treasurer also reserves the right at its sole discretion to reject any proposed contribution, and in particular to reject any proposed contribution made by a pool participant engaged in behavior deemed by the State Treasurer to be abusive of the LGIP -MMF. A pool participant may transfer funds from one LGIP -MMF account to another subject to the same time and contribution limits as set forth in WAC 210.10.060. Contributions Pool participants may make contributions to the LGIP -MMF on any business day. All contributions will be effected by electronic funds transfer to the account of the LGIP -MMF designated by the State Treasurer. It is the responsibility of each pool participant to pay any bank charges associated with such electronic transfers to the State Treasurer. Failure to wire funds by a pool participant after notification to the State Treasurer of an intended transfer will result in penalties. Penalties for failure to timely wire will be assessed to the account of the pool participant responsible. Notice. To ensure same day credit, a pool participant must inform the State Treasurer of any contribution over one million dollars no later than 9 a.m. on the same day the contribution is made. Contributions for one million dollars or less can be requested at any time prior to 10 a.m. on the day of contribution. For all other contributions over one million dollars that are requested prior to 10 a.m., a pool participant may receive same day credit at the sole discretion of the State Treasurer. Contributions that receive same day credit will count, for earnings rate purposes, as of the day in which the contribution was made. Contributions for which no notice is received prior to 10:00 a.m. will be credited as of the following business day. Notice of contributions may be given by calling the Local Government Investment Pool (800- 331 -3284) OR by logging onto State Treasurer's Treasury Management System ( "TMS "). Please refer to the LGIP -MMF Operations Manual for specific instructions regarding contributions to the LGIP -MMF. Direct deposits from the State of Washington will be credited on the same business day. Pricing. Contribution requests received in good order will receive the NAV per unit of the LGIP -MMF next determined after the order is accepted by the State Treasurer on that contribution date. Withdrawals Pool participants may withdraw funds from the LGIP -MMF on any business day. Each pool participant shall file with the State Treasurer a letter designating the financial institution at which funds withdrawn from the LGIP -MMF shall be deposited (the "Letter "). This Letter shall contain the name of the financial institution, the location of the financial institution, the account name, and the account number to which funds will be deposited. This Letter shall be signed by local officials authorized to receive and disburse funds, as described in WAC 210 -10 -020. 7 Disbursements from the LGIP -MMF will be effected by electronic funds transfer. Failure by the State Treasurer to wire funds to a pool participant after proper notification to the State Treasurer to disburse funds to a pool participant may result in a bank overdraft in the pool participant's bank account. The State Treasurer will reimburse a pool participant for such bank overdraft penalties charged to the pool participant's bank account. Notice. In order to withdraw funds from the LGIP -MMF, a pool participant must notify the State Treasurer of any withdrawal over one million dollars no later than 9 a.m. on the same day the withdrawal is made. Withdrawals for one million dollars or less can be requested at any time prior to 10 a.m. on the day of withdrawal. For all other withdrawals from the LGIP -MMF over one million dollars that are requested prior to 10 a.m., a pool participant may receive such withdrawal on the same day it is requested at the sole discretion of the State Treasurer. No earnings will be credited on the date of withdrawal for the amounts withdrawn. Notice of withdrawals may be given by calling the Local Government Investment Pool (800- 331 -3284) OR by logging on to TMS. Please refer to the LGIP -MMF Operations Manual for specific instructions regarding withdrawals from the Fund. Pricing. Withdrawal requests with respect to the LGIP -MMF received in good order will receive the NAV per unit of the LGIP -MMF next determined after the order is accepted by the State Treasurer on that withdrawal date. Suspension of Withdrawals. If the State Treasurer has determined that the deviation between the Fund's amortized cost price per share and the current net asset value per share calculated using available market quotations (or an appropriate substitute that reflects current market conditions) may result in material dilution or other unfair results, the State Treasurer may, if it has determined irrevocably to liquidate the Fund, suspend withdrawals and payments of withdrawal proceeds in order to facilitate the permanent termination of the Fund in an orderly manner. The State Treasurer will distribute proceeds in liquidation as soon as practicable, subject to the possibility that certain assets may be illiquid, and subject to subsequent distribution, and the possibility that the State Treasurer may need to hold back a reserve to pay expenses. The State Treasurer also may suspend redemptions if the New York Stock Exchange suspends trading or closes, if US bond markets are closed, or if the Securities and Exchange Commission declares an emergency. If any of these events were to occur, it would likely result in a delay in the pool participants' redemption proceeds. The State Treasurer will notify pool participants within five business days of making a determination to suspend withdrawals and /or irrevocably liquidate the fund and the reason for such action. Earnings and Distribution LGIP -MMF Daily Factor The LGIP -MMF daily factor is a net earnings figure that is calculated daily using the investment income earned (excluding realized gains or losses) each day, assuming daily amortization and /or accretion of income of all fixed income securities held by the Fund, less the administrative fee. The daily factor is reported on an annualized 7 -day basis, using the daily factors from the previous 7 calendar days. The reporting of a 7 -day annualized yield based solely on investment income which excludes realized gains or losses is an industry standard practice that allows for the fair comparison of funds that seek to maintain a constant NAV of $1.00. LGIP -MMF Actual Yield Factor The LGIP -MMF actual yield factor is a net daily earnings figure that is calculated using the total net earnings including realized gains and losses occurring each day, less the administrative fee. 8 Dividends The LGIP -MMF's dividends include any net realized capital gains or losses, as well as any other capital changes other than investment income, and are declared daily and distributed monthly. Distribution The total net earnings of the LGIP -MMF will be declared daily and paid monthly to each pool participant's account in which the income was earned on a per -share basis. These funds will remain in the pool and earn additional interest unless withdrawn and sent to the pool participant's designated bank account as specified on the Authorization Form. Interest earned will be distributed monthly on the first business day of the following month. Monthly Statements and Reporting On the first business day of every calendar month, each pool participant will be sent a monthly statement which includes the pool participant's beginning balance, contributions, withdrawals, transfers, administrative charges, earnings rate, earnings, and ending balance for the preceding calendar month. Also included with the statement will be the monthly enclosure. This report will contain information regarding the maturity structure of the portfolio and balances broken down by security type. Ill.
