In preparing the Connect SoCal vision, the Southern California Association of Governments engages in a Bottom-Up Local Input and Envisioning Process to solicit information from local cities, counties and subregions on their most current land use, anticipated population/household/employment growth, resource areas, sustainability practices, and local transit-supportive measures to help understand how the region is growing and the extent to which we are meeting our climate goals.
This page is for local jurisdictions in Southern California to access and review SCAG's existing data sets as part of the Local Input Process.
Updated information from local cities will then be used to develop and evaluate potential future development scenarios for Southern California, and their respective impacts on greenhouse gas emissions. Input from jurisdictions on locally anticipated household and population growth will also be used by SCAG as part of the regional housing need determination process with the California Department of Housing and Community Development (HCD).
For ease of review, core data items have been mapped in draft format and assembled in an individual map book for each local jurisdiction (available below). County-level maps showing the first draft of anticipated growth are also accessible for review.

Please note that SCAG’s draft data is undergoing refinement based on feedback from local jurisdictions, and material included here is subject to revision; inquiries for official data should be directed to each respective local jurisdiction.
