SB 1423: Regional planning: standardized spatial planning datasets.
What SB 1423 does, verified October 2, 2026
The bill aims to improve transportation in California by allocating funds for safe streets projects. At least 50% of interregional and regional transportation improvement program funds must be prioritized for safe streets projects in areas of transit-oriented development zones with inadequate pedestrian safety and mobility access. The bill also redefines the active transportation program as the safe streets program, focusing on projects that benefit disadvantaged communities and improve connectivity and mobility for nonmotorized users. To streamline the application process, the bill requires a simplified initial application and a more comprehensive final application for review.

LEGISLATIVE COUNSEL'S DIGEST
SB 1423, Stern. Regional planning: standardized spatial planning datasets.
Existing law establishes the Office of Land Use and Climate Innovation in the Governor’s office for the purpose of serving the Governor and the Governor’s cabinet as staff for long-range planning and research and constituting the comprehensive state planning agency.
This bill would require the office, on or before July 1, 2028, to compile, standardize, maintain, and make publicly available through a consolidated online platform a core set of statewide standardized spatial planning datasets, as defined. The bill would require the datasets to include specified categories of information, including hazardous data, natural resource sensitivity data, and agricultural value data, as provided. The bill would also require the office, on or before January 1, 2029, to develop and provide guidance for agencies to inform how to use and integrate the datasets in regional planning processes and products. The bill would require the office to update those datasets as new or revised data becomes available from the originating state or federal agencies.
This bill would permit state, regional, and local governments to consider use of the standardized spatial planning datasets published by the office in the development and production of land use and infrastructure plans, as specified. The bill would require the office to provide technical assistance, upon request, for use of the data from these provisions. The bill would specify that it does not create new regulatory requirements, regulate land use or zoning, establish land use designations, or preempt the local land use authority of cities and counties.
The people of the State of California do enact as follows:
SECTION 1.
The Legislature finds and declares all of the following:(a) Climate change is intensifying wildfire, flood, drought, and sea level rise risks across California. Sound land use planning that accounts for these risks is essential to protect the lives, property, and fiscal health of Californians.
(b) California has invested substantially in publicly available spatial data and planning tools to support land use decision making. The Governor’s Office of Land Use and Climate Innovation, in coordination with state agencies, maintains datasets and mapping tools that provide critical information on hazards, environmental resources, infrastructure, and land use conditions.
(c) Standardizing statewide spatial planning data will make planning decisions and their outcomes more consistent with the state’s planning priorities, such as those specified in Section 65041.1 of the Government Code, promote transparency and consistency across plans and documents, reduce costs, promote efficiencies, and support more resilient and equitable communities.
(d) Standardized spatial planning datasets are intended as tools to inform and guide future planning decisions and to support voluntary data-informed planning across state, regional, and local agencies.
SEC. 2.
Section 65040.18 is added to the Government Code, to read:65040.18.
(a) For purposes of this section, the following terms have the following meanings:(1) “Consolidated online platform” means a publicly accessible online portal maintained or designated by the office that provides access to standardized spatial planning datasets as a decision support tool.
(2) “Standardized spatial planning dataset” means geospatial data layers that have been compiled, standardized, and published by the office pursuant to this section.
(b) On or before July 1, 2028, the office shall compile, standardize, maintain, and make publicly available through a consolidated online platform a core set of statewide standardized spatial planning datasets.
(c) The standardized spatial planning datasets shall include the following categories of information:
(1) Hazard data, including, but not limited to, all of the following:
(A) State and local responsibility area high and very high fire hazard severity zones as determined by the Department of Forestry and Fire Protection.
(B) One-hundred-year and 500-year flood plains as designated by relevant state and federal agencies.
(C) Coastal and inland areas subject to sea level rise inundation as identified by the Ocean Protection Council.
(2) Natural resource sensitivity data, including, but not limited to, all of the following:
(A) Wetlands and riparian areas as mapped by relevant state and federal agencies.
(B) Biological resource areas that contain, support, or are necessary to sustain important biological or ecological resources, including species biodiversity, significant habitats and wildlife corridors as determined by the Department of Fish and Wildlife and the Natural Resources Agency.
(C) Legally protected lands and lands under a conservation easement.
(3) Agricultural value data, including, but not limited to, both of the following:
(A) Prime and unique farmlands and farmland of statewide and local importance as classified by the Department of Conservation.
(B) Lands subject to Williamson Act contracts pursuant to Chapter 7 (commencing with Section 51200) of Part 1 of Division 1 of Title 5.
(d) On or before January 1, 2029, the office shall develop and provide guidance for agencies to inform them on how to use and integrate standardized spatial planning datasets in regional planning processes and products.
(e) The office shall update the standardized spatial planning datasets as new or revised data becomes available from the originating state or federal source agencies.
SEC. 3.

(2) Regional transportation plans and sustainable communities strategies prepared pursuant to Section 65080.
(3) Regional housing needs allocations processes pursuant to Section 65584.
(4) Climate action plans.

(c) Nothing in this section or in Section 65040.18 creates new regulatory requirements, regulates land use or zoning, establishes land use designations, or preempts the local land use authority of cities and counties.
