ITEM TITLE: Update of the Multi -year Irrigation System Rebuild Project
SUBMITTED BY: Dave Brown - Water /Irrigation Division Manager
Mike Shane, Water /Irrigation Engineer
CONTACT PERSON /TELEPHONE: Dave Brown — 509 - 576 -6480
SUMMARY EXPLANATION:
Attached is an updated report to City Council on the multi -year Irrigation System Rebuild
project. 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 33,115
feet of mains (6.3 miles) and 1,378 services of the 181,364 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, with the second bond of $3.5 million expected by the end
of 2011. The $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 2012;
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 (Le:: payments on bonds and other debt). While it is unlawful

for revenue generated by the Utility to be used to support other funds, pp , it is also unlawful to set
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 (Replacement Complete)
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) Fruitvale Canal Improvements (ongoing project started in 2003) a,
9) 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 is completed.
• The General System Phase 4 began in 2010 and will be completed in the 2011/12
construction season.
Current Activities:
In addition to beginning the General Irrigation System Replacement Phase 4 /Stage 2 in the
winter of 2011/2012, the Fruitvale Canal will be piped from N. 5 Ave. to N. 7 St. (excluding
BNSF right -of -way).
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.

The accomplishments to date are significant, as is the work remaining to complete the adopted
plan and provide for the integrity of the City owned irrigation systems. 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. .
