Intergovernmental Review (IGR)

image banner: Intergovernmental Review (IGR)

SCAG’s Intergovernmental Review (IGR) Program is responsible for reviewing applications for federal grants and financial assistance programs, federally required state plans, federal development activities, and federal environmental documents pursuant to Presidential Executive Order 12372. Additionally, SCAG’s IGR Program is responsible for reviewing regionally significant plans, projects, and programs per the California Environmental Quality Act (CEQA) and ensuring that these projects are consistent with SCAG’s adopted regional plans. This process helps identify the project’s impact on a regional scale and how the proposed project contributes to our region’s plan and vision.

SCAG is also the designated Regional Transportation Planning Agency under state law, and is responsible for preparation of the Regional Transportation Plan (RTP) including the Sustainable Communities Strategy (SCS) pursuant to Senate Bill (SB) 375. As the clearinghouse for regionally significant projects per Executive Order 12372, SCAG reviews the consistency of local plans, projects, and programs with regional plans. SCAG’s feedback is intended to assist local jurisdictions and project proponents to implement projects that have the potential to contribute to attainment of Regional Transportation Plan/Sustainable Community Strategies (RTP/SCS) goals and align with RTP/SCS policies.

IGR Clearinghouse Report

The Intergovernmental Review Clearinghouse Report summarizes federal grant applications, environmental documents and other information received by SCAG's IGR Section. The Clearinghouse Report consists of two sections, Federal Grant Listing and Environmental Documentation Listing.

The Federal Grant Listing is provided to inform your organization of all grant applications for federal assistance from our region in accordance with Executive Order 12372. The Environmental Documentation Listing describes regionally significant and non-regionally significant projects voluntarily submitted for review by local governments. Environmental documents received include Notices of Preparation, Environmental Impact Reports, Environmental Impact Statements, Negative Declarations and Mitigated Negative Declarations.

Project descriptions on both listings are organized by county: Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura. State plans and other multi-county plans, projects and proposals are grouped under the “Multi-County” heading at the beginning of the IGR Clearinghouse Report. To include the interest of your jurisdiction or comment on proposed comprehensive planning, area wide coordination or environmental impacts please contact the IGR Section.

See above for IGR Clearinghouse Reports, both recent reports and report archives.
