SCAG has developed its regional geospatial dataset of land use information at the parcel-level (approximately five million parcels) for 197 local jurisdictions in its region. The regional land use dataset is developed (1) to aid in SCAG’s regional transportation planning, scenario planning and growth forecasting, (2) facilitate policy discussion on various planning issues, and (3) enhance information database to better serve SCAG member jurisdictions, research institutes, universities, developers, general public, etc. It is the most frequently and widely utilized SCAG geospatial data. In 2024, SCAG successfully released the final 2019 regional land use dataset, developed for the Final Connect SoCal 2024, the 2024-2050 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), which includes general plan land use, specific plan land use, zoning code and existing land use information. The 2019 regional land use dataset was reviewed by local jurisdiction, and SCAG staff made every effort to ensure the data reflect local jurisdiction’s input received during the Connect SoCal 2024 Local Data Exchange process. Following the successful adoption of Connect SoCal 2024, SCAG launched the 2024 regional land use data development process to update parcel-level land use information in preparation for Connect SoCal 2050, the 2028-2050 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). Between summer and fall of 2024, SCAG staff collected 2024 parcel boundary GIS files and tax roll property data from county assessor’s offices. After several months of data standardization and cleanup, SCAG released the 2024 parcel boundary GIS files in March 2025, followed by the 2024 Annual Land Use dataset in June 2025. SCAG staff migrated the 2019 existing land use information to 2024 parcel polygons and incorporated any recent land use changes since the year 2019. As a part of the update process, SCAG staff identified newly developed parcels that were previously vacant by analyzing county assessor’s tax roll information (including use codes and assessed valuations) and building footprint information. Additional geoprocessing was performed to improve accuracy using reference layers, such as California Protected Areas Database (CPAD), California School Campus Database (CSCD), Farmland Mapping and Monitoring Program (FMMP)’s Important Farmland, U.S. Department of Defense’s Military Installations, Ranges, and Training Areas (MIRTA).
