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.

(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.
