Natural Resources Element Goal 2.0: Protect our water and energy resources from pollution

Policy 2.3: Reduce the amount of water used for landscaping through the use of native and
drought - tolerant plants, proper soil preparation, and efficient irrigation systems as parks are built
or renovated.
7. DISCUSSION and BACKGROUND
Background
Fred Barrera, Belmont, Serrano and Santiago Hill Parks, comprise about 17.5 acres of landscape,
lighting, and other infrastructure maintained by the City under service agreements. The cost for
all maintenance in the parks, including irrigation water, has steadily increased in recent years and
the aging infrastructure is demanding more resources to maintain it. The irrigation system is
extensive, providing water to turf, shrubs and trees throughout the parks. The City has an on-
going commitment to reduce water usage. A significant reduction in irrigation water use through
improved efficiency in its delivery is imperative to meet the commitment and maintain healthy
parks.
Other efforts are being planned and implemented as part of an overall, comprehensive plan to
reduce water consumption in City landscapes. These include future removal of turf in parks and
other City facilities where appropriate, replacing it with drought - tolerant plant designs;
retrofitting irrigation systems to low flow, sub - surface type designs; mulching planters; and as
funds are available, continuing education to staff on water management and irrigation
technology.
To best meet the City's needs in ensuring consistent equipment throughout the park system, as
well as reduce mark -up costs on equipment purchase, the City bid the purchase of Calsense
equipment and the installation of this equipment separately. The agenda presented here is for
purchase of equipment only. City Council is being asked to consider an award to install the
equipment to STL Landscape, Inc. for amount of $98,000 in a separate item on the same agenda.
Discussion
In an effort to accomplish ongoing reductions in water consumption for public landscape, the
Community Services Department is proposing to replace irrigation controllers at four parks with
Calsense centralized irrigation control systems. Calsense irrigation control systems have already
been introduced at other City parks and are proving to accomplish significant savings as well as
maximizing staff's ability to more effectively manage the systems throughout the City. The
Community Services Department advertised Bid 167 -42 on April 26, 2017 and received five bid
proposals on May 25. The low bid was received from SiteOne Landscape Supply LLC for
$51,614.41, plus tax at 7.75% ($4,000.12), for a total cost of $55,614.53. This price is $4,385
below the project estimate. A bid summary is attached.
Calsense Installation at Various Parks is approved CIP No. 30047 funded by Park Acquisition
fees, Fund 510. The purchased equipment is anticipated to be installed beginning in August.
There should be minimal to no impact to the public during installation.
