DESCRIPTION:
Background
The 2024-2029 Capital Improvement Program (CIP) includes the Irrigation System Upgrades
Project, CIP No. GI0224. The Project provides for the procurement and installation of new
irrigation controllers, master valves, associated communication system upgrade s, overall
system optimization, and operational training. The Project is anticipated to reduce the City’s
irrigation water use by eight percent annually (roughly $50,000 annually) and achieve overall
operational efficiencies by completing the following improvements to the City’s irrigation
system:
Communications - Upgrade the existing system to establish communication between
the central irrigation system and irrigation controllers throughout all City -maintained
landscapes.
System Optimization - Provide advanced, site-specific irrigation scheduling based on
each location’s soil type, plant type, slope, sun, shade, etc., to improve overall water
efficiency and landscape quality for the City’s largest landscapes. The system will also
automatically adapt to weather conditions, such as canceling scheduled irrigation prior
to an anticipated rain event.
Operations - Provide operational and training support for Staff and contractors to
maintain and operate the upgraded system.
Controller and Valve Upgrades - Install 65 new controllers with cellular
communications into the central irrigation system and replace 30 master and flow
control valves that can shut off remotely or automatically in an unscheduled flow.
Total Funding $1,840,000

Controller and Valve Upgrades
On February 6, 2024 the City Council adopted Resolution No. 09-24 authorizing the purchase
of irrigation controllers from SiteOne Landscape Supply, LLC in an amount not to exceed
$650,000. In addition, on June 3, 2025 the City Council adopted Resolution No. 34 -25
awarding a construction contract of $415,157 to CLS/Cervantes Landscape Services, Inc. for
the Project and authorizing the City Manager to approve change orders up to a contingency
amount of $100,000, for a total potential construction contract of $515,157.
Construction is nearly complete and the Project is expected to have a balance of $332,692,
which can be used to expand the irrigation upgrades to other City infrastructure. Staff is now
seeking to increase the change order contingency with CLS/Cervantes by $60,000 (total not-
to-exceed potential construction contract of $575,157) for the additional work and increase the
purchasing order authority with SiteOne by $180,000 (total purchase of $830,000) to procure
additional irrigation controllers and related equipment. This will allow the City to upgrade up to
20 additional parks and facilities while staying within the total budget for this Project.
