Comprehensive Land Use and Regional Growth Projects

Intergovernmental Review

In 1973, SANDAG was designated the area-wide clearinghouse for the review of environmental documents and for projects to be conducted or located in the San Diego region. It was re-designated as the area-wide clearinghouse in 1984. This designation is set under the intergovernmental review regulations of the federal government and the State of California, the California Environmental Quality Act, and the National Environmental Policy Act.

Per state law, SANDAG has the authority to determine whether a project or plan will need to be reviewed for regional significance. SANDAG staff reviews projects and determines if they are regionally significant based on the amount of traffic generated and other regionally significant issues. If significant, environmental review of projects should include consideration of applicable policy objectives contained in the Regional Comprehensive Plan (RCP) and the 2050 Regional Transportation Plan (RTP).

For projects considered to have significant impacts SANDAG staff write comment letters from a regional perspective that emphasize the need for land use and transportation coordination and are based on policies contained in the RCP and the 2050 RTP.

In addition to the RCP and RTP, we encourage project or plan developers, where appropriate, to evaluate the project based on the following SANDAG publications:

  • San Diego Region Aggregate Supply Study
  • Designing for Smart Growth, Creating Great Places in the San Diego Region
  • Planning and Designing for Pedestrians, Model Guidelines for the San Diego Region
  • Trip Generation for Smart Growth
  • Parking Strategies for Smart Growth
  • Regional Multimodal Transportation Analysis: Alternative Approaches for Preparing Multimodal Transportation Analysis in Environmental Impact Reports
  • Integrating Transportation Demand Management into the Planning and Development Process - A Reference for Cities
  • Project Manager
