In accordance with the California Environmental Quality Act (CEQA), the Southern California Association of Governments (SCAG), as Lead Agency, prepares a Program Environmental Impact Report (PEIR) for the Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), which is updated every four years.
The program level environmental impact report conducts a regional-wide assessment and discloses potential impacts of the RTP/SCS on the environment at a regional level. The PEIR also considers program-wide mitigation measures and broad policy alternatives. The PEIR provides a foundation for subsequent, project-specific environmental reviews that may be conducted by local implementation agencies serving as CEQA lead agencies for later projects with narrower scope.
Connect SoCal 2024 Draft PEIR
SCAG, as the Lead Agency pursuant to CEQA, has prepared a Draft Program Environmental Impact Report (2024 Draft PEIR) (State Clearinghouse No.: 2022100337) for the proposed 2024-2050 Regional Transportation Plan and Sustainable Communities Strategy (RTP/SCS), also referred to as “Connect SoCal 2024”, “2024 RTP/SCS”, “Plan”, or “Project”. The Draft 2024 PEIR serves as a programmatic document that presents a region‐wide assessment of potential environmental effects of Connect SoCal 2024.
