San Mateo County is actively engaged in various environmental initiatives aimed at preserving natural resources and enhancing climate resilience. These efforts involve collaboration between local organizations, government agencies, and community members.
Stormwater Management Enhancements
In April 2026, the U.S. Environmental Protection Agency (EPA) announced a $34 million Water Infrastructure Finance and Innovation Act (WIFIA) loan to the Daly City Joint Powers Financing Authority. This funding supports the Vista Grande Drainage Basin Improvement Project, which aims to increase stormwater management capacity, reduce flooding risks, and improve regional water quality. The project includes replacing an undersized canal, enlarging a tunnel, upgrading the overflow system to Lake Merced, and constructing a new outlet to the Pacific Ocean. These improvements are expected to stabilize Lake Merced’s water levels and create approximately 500 jobs during construction and operations. Source
Habitat Restoration Efforts
The San Mateo County Parks Foundation has been supporting habitat restoration at Edgewood Park and Natural Preserve for nearly two decades. This preserve is home to over 500 plant species, including rare and endangered ones, and more than 80 species of resident and migratory birds. Collaborative efforts with Creekside Science and Friends of Edgewood focus on protecting this extraordinary biodiversity through various programs, such as bluebird monitoring and invasive species management.
