922-980 S. Claremont Street Project

The 922-980 S. Claremont Street Project, identified by solicitation PA-2024-062, is a development initiative by the City of San Mateo to establish a self-storage facility on a 1.37-acre site. The project involves the rehabilitation of three existing single-story buildings totaling 25,186 square feet and the construction of a new two-story storage building of approximately 51,873 square feet, including a basement level. Together, these four buildings will provide 76,767 square feet of space comprising 591 storage units, 717 storage lockers, 118 wine storage units, and approximately 2,028 square feet of office space. Additional site improvements include a 20-space surface parking lot, landscaping, frontage improvements, and both on- and offsite utility connections. The project is subject to strict environmental and safety compliance, including the California Environmental Quality Act and a Mitigated Negative Declaration. Because the site is identified as a leaking underground storage cleanup site, the contract mandates a comprehensive Site Management Plan and a project-specific Health and Safety Plan. Key requirements include specialized OSHA training for personnel, baseline medical examinations, and rigorous soil characterization and approval processes for the disposal or reuse of impacted soil. Construction is anticipated to take approximately 1.5 years, with an estimated schedule running from April 2026 through December 2027. Technical analyses have confirmed that proposed wastewater flows are lower than existing levels, eliminating the need for sewer main improvements.
