For the first time in California history, all coastal cities must plan for sea-level rise, thanks to the passing of SB 272 that Greenbelt Alliance and other advocates supported. The new law requires all cities to develop strategies and recommend projects to address future sea level rise by 2034, with plans mandated and guided by local governance. SB 272 will authorize coastal regulators like the Bay Conservation Development Commission (BCDC) to have the power to approve or deny plans for adaptation projects and development along the shoreline.
