With warmer temperatures and more extreme weather, sea level rise modeling indicates Contra Costa County’s shoreline, which includes a variety of residential, business, industrial, infrastructure and natural sites, can expect to be subject to more severe and frequent flooding.

To address sea level rise, the Board established the Contra Costa Resilient Shoreline Ad Hoc Committee at the May 16, 2023, Board of Supervisors meeting. Supervisor John Gioia, whose district borders the San Francisco Bay, was appointed as Chair, and Supervisor Diane Burgis, whose district borders the Sacramento-San Joaquin Delta, was appointed as Vice-Chair of the Committee.

Funded through Measure X, the Committee will develop recommendations to the Board on work the County can do to plan for sea level rise and improve shoreline resiliency, which could potentially include a sea level rise resilience and adaptation plan. This would build on the County’s past work on collaborative regional efforts to characterize sea level rise risks with the San Francisco Bay Conservation and Development Commission and the Delta Stewardship Council.

The Plan could include recommendations for built and natural infrastructure improvements and potential land use planning changes, implementation strategies, and participatory engagement opportunities for stakeholders. With the creation of this Committee, the County will be better prepared to adapt to rising sea levels with strategies specific to the current and future needs of Contra Costa communities.

The Contra Costa Resilient Shoreline Ad Hoc Committee’s first meeting will occur on Thursday, October 12, 2023, from 10 a.m. to 11:30 a.m. via Zoom with in-person meeting locations listed in the published agenda packet. To sign up for email updates, visit the Contra Costa Legistar website.
