Daly City awards $2.34 million contract for Westlake slurry seal and Vision Zero striping changes

The council approved a construction contract to slurry-seal about 13.9 miles of Westlake neighborhood streets and to update striping and crosswalks as part of the city’s pavement preservation and Vision Zero efforts.

Public works staff recommended awarding the contract to Graham Contractors (San Jose), the low bidder at $2,341,427.51. The total project estimate, including a 20% contingency for inspection and administration, was presented at about $2.81 million. Staff said slurry seal preserves pavement life, reduces water penetration and lowers long‑term maintenance costs; the project will include updated lane lines, curb-ramp alignments and high-visibility crosswalks on the city’s high-injury network.

“Streets selected to be surface sealed are based on the city's seven-year master plan, the city's computer-based pavement management system recommendations, visual observations and other upcoming or associated work,” the public works presentation said. If awarded, staff estimated construction would start in July 2026 and be complete by January 2027.

Council members sought assurances about post-application cleanup after hearing reports of loose aggregate on streets in prior projects. Public works staff said inspectors will verify the contractor’s mixture and ensure adequate street sweeping; staff will require follow-up remediation where necessary.

Council approved the contract and authorized the city manager to execute necessary documents.

What’s next: Public works will issue the construction notice, monitor contractor performance and schedule sweeping and remedial work where needed during and after the slurry application period.
