This half-acre empty lot sits directly across from Walnut Park, at the junction of Petaluma Boulevard and D Street, a major intersection traveled by residents and visitors alike. This property had been a Unocal gas station starting in 1969, but was identified as a Leaking Underground Storage Tank (LUST) site by the California State Water Resources Control Board needing remediation. The station building and the underground storage tanks were removed in 1991 and 1992. The site has been vacant and behind a chain link fence since then.
In 2025, a Missouri company, West Four Properties Inc., purchased the land. In an October 2025 report to the Regional Water Quality Control Board, San Francisco Bay Region, a contractor for the owner stated: “As of May 1, 2025, the property was acquired by WFP. As part of the transaction, WFP agreed to assume responsibility for environmental remediation of the property in preparation for yet to be determined redevelopment.“
