Amend the Fiscal Year 2026 Budget Appropriation for the Stormwater Management Fund (requires a 2/3 vote) by: a.

EXECUTIVE SUMMARY Hamilton Avenue from Center Drive to Rhodes Drive is prone to flooding due to an undersized storm drain system. The 2015 Storm Drain Master Plan identified upsizes to the storm system at Hamilton Avenue as a high priority project, and this project is included among the 13 high priority capital projects in the 2017 Stormwater Management ballot measure. The Hamilton Avenue Capacity Upgrades project will install larger storm pipes and manholes to convey the storm runoff from a 10-year storm event. Construction bids were solicited through OpenGov and four bids were received. The construction contract is being awarded to the lowest responsible bidder. A budget amendment in the Stormwater Management Fund is needed to fully fund the contract. BACKGROUND current capacity of the Hamilton Avenue storm drain line is 15-20 cfs, while the new system will have a capacity of 90 cfs. Following the New Year’s Eve 2022 San Francisquito Creek flooding event, staff reprioritized the project to be built sooner, in recognition of its ability to partially mitigate the impacts of any future Creek flooding that may occur before the Reach 2 flood control project is completed. The project includes installing 100 linear feet of 36-inch pipe on Center Drive starting at Hamilton Avenue going towards Dana Avenue. This segment is part of the Center Drive Capacity Upgrades project, another of the projects approved by voters that is currently scheduled for Fiscal Year 2027. The segment was advanced to coordinate with the Office of Transportation’s project to construct new concrete median islands and redesign the traffic circle at the Hamilton Avenue, Southwood Drive and Center Drive intersection.
