Bill > SB1423

This bill requires the California Governor’s Office of Land Use and Climate Innovation to compile, standardize, and maintain a centralized online platform containing statewide spatial planning datasets—which are digital maps and geographic information system (GIS) data layers used for mapping—by July 1, 2028. These datasets must cover specific categories such as hazard data (including wildfire zones, floodplains, and sea level rise areas), natural resource sensitivity data (such as wetlands, wildlife habitats, and protected lands), and agricultural value data (including important farmlands and lands protected by the Williamson Act, a state law providing tax relief for agricultural land preservation). Furthermore, the office must provide guidance on how to integrate these datasets into regional planning by January 1, 2029, and continuously update the information as new data becomes available from originating agencies. State, regional, and local governments are permitted to use these standardized datasets when developing local land use and infrastructure plans, such as general plans and climate action plans, though they may also use more precise local data if available. Finally, the legislation explicitly clarifies that these mapping tools do not create new regulations, dictate land use or zoning, or override the traditional land use authority of local cities and counties.
