CA AB2373

Authorizes local governments in California's coastal zone to use a "neighborhood-scale adaptation approach" when developing land use policies for their local coastal programs or sea level rise plans required by 2034

Defines neighborhood-scale adaptation as allowing jurisdictions to identify specific areas or assets—such as neighborhoods, beaches, watersheds, or infrastructure—that share geologic or land use characteristics for focused sea level rise planning

Permits local governments to develop tailored adaptation strategies for different areas based on geophysical features and development types, rather than applying uniform policies across entire jurisdictions

References the Ocean Protection Council's 2024 guidance projecting sea level rise of 6.1 to 11.9 feet along California's coastline by 2150 under highest-risk scenarios

Requires implementation to remain consistent with existing California Coastal Act requirements and Coastal Commission oversight
