Local Data Exchange Frequently Asked Questions
- Why Participate in the Local Data Exchange (LDX)?
The LDX process is the primary input opportunity for local jurisdictions to participate in the development of SCAG’s long-range regional plan. The LDX ensures that SCAG integrates local input and uses accurate data in developing key technical components of the plan, including the Forecasted Regional Development Pattern. As Connect SoCal data and models support plan implementation and local funding opportunities, the LDX ensures that local and regional plans are mutually reinforcing.
- How Can Local Jurisdictions Provide Verification and Share Data With SCAG?
Input from local jurisdictions is critical to ensure SCAG has the most accurate data available. Data shared through the LDX process are preliminary, and local jurisdictions are asked to review and provide updates and corrections to data and information within their local purview, including local land use, preliminary forecasted regional development pattern, and select transportation data.
Jurisdictions can share their data and provide verification via email or an upload link. Local input and verification are due to SCAG on Nov. 20, 2026, for possible inclusion in draft plan development.
- Where can I get help with the LDX process?
Technical assistance requests and LDX process questions can be submitted through SCAG’s Local Information Services Team (LIST) at list@scag.ca.gov. Once one-on-one meetings are scheduled, SCAG will assign a LIST team member as point of contact to each jurisdiction. The SCAG point of contact will be available for technical assistance and questions throughout the process.
