This project has its origins more than a decade ago and it is easy to lose track of its importance, progress, and status as time marches on. You will find a memo that contains the background, chronology of activities, the current activities, and the plan for the next few years and a detailed list of accomplishments. Included are the projects completed by the city Irrigation Crew. Our Crews have replaced some 27,515 II feet of mains (5.2 miles) and 1,233 services of the 159,234 feet of pipe that has been replaced to date. You will also find a table with the projects listed by system, a spreadsheet showing the finances and a map of the system showing the pipes that have been replaced. There are about three or four more years to complete the initial high priority projects. After the high priority projects are complete we will begin updating and refurbishing the medium priority parts of the irrigation system that were indentified in the December 1999 Master Irrigation Plan. The project is under budget and ahead of schedule. Once the report is accepted it will be posted to the City's web site.

RE: Irrigation System Rebuild Update Periodically, staff has provided the City Council an update of the multi -year Irrigation System Rebuild project. In that this project has its origins more than a decade ago, it is easy to lose • track of its importance, progress, and status as time marches on. Background: During the many Council Study Sessions, Meetings, Public Hearings, and Public Information Meetings over the past decade, plans for the future of the City's Irrigation System were discussed in detail. Based on those discussions, the City Council authorized the following plan of action: 1) Fund rehabilitation /replacement of the General Irrigation System replacement through a combination of revenue bonds ($10M) and funds generated through a CIP rate component. Total cost estimated to be $13- $14million; 2) Revenue bonds to be issued in two increments of $5M each. The first bond of $5 million was obtained in 2004, the second has yet to be issued, and $3 -$4 million difference between the bond proceeds and the estimated total project cost is planned to be funded from monies collected as part of the CIP rate; 3) Completion of the General Irrigation System replacement project scheduled for 2013; 4) The General Irrigation System project is considered the highest priority; 5) Bond repayment is from the funds collected through revenues generated by the CIP ' rate. (Rates are to be set at a level sufficient to pay the costs of the rehabilitation /replacement project.) Note: The Irrigation Utility is an "Enterprise Fund ", which essentially means that the Utility should be self- sufficient. By law, the Utility may not support any other fund through its rate structure; however, rates must be set at a level that will cover all operating and capital costs of the Utility, including debt service (i.e.: payments on bonds and other debt). While it is unlawful III for revenue generated by the Utility to be used to support other funds, it is also unlawful to set David E. Brown Water /Irrigation Manager (509) 575 -6204 Fax (509) 575 -6187 dbrown @ci.yakima.wa.us rates at a level that is insufficient to cover the Utilities bond payments, as this would be an unconstitutional impairment of a contract. Therefore, a cost of service study is performed periodically to review the rate structure and ensure that rates are set at a prudent operating and legally authorized level. Chronology: • 1997 Irrigation System Formed including a Capital Improvement Fund • 1998 completed first General System upgrade project • December 1999 Master Irrigation Plan completed. The Plan included evaluation of all of the City owned irrigation systems, developed a Capital Improvement Plan (CIP) and identified eight systems rating a "high" priority for repair /replacement: 1) Capital Hill (Scheduled for replacement 2009/10 & 2010/11) 2) Nob Hill (Replacement Complete) 3) Hillcrest (Replacement Complete) 4) Brackett Park (Replacement Complete) 5) West Yakima (Replaced 2/3 of the system) 6) North Hillcrest A (Replacement Complete) 7) DeAtley Park (Replacement Complete) 8) General (ongoing project started in 1998) • The General System Phase 2 began in 2004 and is completed. • The General System Phase 3 began in 2007 and will be completed in the 2009/10 construction season. Current Activities: In addition to beginning the General Irrigation System Replacement Phase 4 /Stage 1 in the winter of 2010/2011, the east half Capital Hill System is currently under design and scheduled for replacement. With the replacement of the high priority systems nearly complete, remaining replacement projects will be based on funds available in the CIP budget and system repair history. Below is a list of the projects completed since 1997. Also attached is an.accounting of the funds collected and spent in the Capital Improvements Program, a table summarizing the completed projects and three maps. David E.

City staff is working to complete this work in as cost effective a manner as possible. Irrigation construction projects to date have been completed on schedule and within construction estimates. You will note that a number of projects were completed with in -house forces, depending on maintenance workload and project complexity these efforts on the part of City crews can result in significant savings, a change of pace and cross - training opportunities for the crews. • • • • • • • • • .
