TITLE: Approve a Midyear Capital Improvement
Project—Shoreline Sailing Lake Pump
Replacement
Acting in its capacity as Board of Directors of the Shoreline Regional Park Community, approve a
midyear Capital Improvement Program project, Shoreline Sailing Lake Pump Replacement, and
transfer and appropriate $400,000 from the Shoreline Regional Park Community Fund to the new
project.
BACKGROUND
The water in Shoreline Sailing Lake is supplied by the San Francisco Bay through the Sailing Lake
pump located at the south end of Inner Charleston Slough. To maintain the quality of the water
in the Sailing Lake, approximately 10 million gallons per day of water is pumped into the lake.
Water volume is managed by an overflow weir where the water discharges into Permanente
Creek.
In July 2020, the primary Sailing Lake pump failed and was sent out for repair, and the backup
pump was installed. During this time, the pump manufacturer's facility that produces the
required repair parts shut down operations due to the COVID-19 pandemic. In November 2021,
the backup Sailing Lake pump failed after multiple repair attempts by staff and the City's pump
services contractor. With both Sailing Lake pumps out of commission, rental pumps were
brought in to maintain Sailing Lake operations at a cost of $15,000 per month plus installation
and removal fees. The rental pumps are a different style of pump that sit above ground as they
are not able to fit within the pump well and are noisy. Due to the expense and incompatibility
with the Shoreline Lake area, the rental pumps should be replaced as soon as possible. However,
parts are still unavailable to repair the two City -owned pumps, and there is no indication of when
they will become available.
ANALYSIS
City staff worked with the City's pump repair contractor, engineering consultants, and pump
distributors to locate and verify compatibility for a new submersible pump from a different

manufacturer. This new pump can utilize the existing electrical connections and intake and
discharge piping, eliminating the need for additional design work and heavy construction. These
project efficiencies will reduce the time and cost to install a new pump.
The Sailing Lake Pump Replacement project will purchase two 65 -horsepower submersible
pumps (one for installation and one spare) and all required installation materials. These pumps
will be rated to operate in a marine environment and provide the needed seawater pumping
capacity of 10 million gallons per day for Sailing Lake operations. To avoid future issues with
replacement parts and pump serviceability, staff will procure pumps with locally available
replacement parts and servicing.
FISCAL IMPACT
There is sufficient funding in the Shoreline Regional Park Community Fund for the recommended
transfer and appropriation of the $400,000 for the Sailing Lake Pump Replacement project.
ALTERNATIVES
1. Do not create a midyear CIP for a Sailing Lake Pump replacement, and continue to use rental
pumps and study other alternatives.
2. Provide other direction.
