Local Development-Intergovernmental Review (LD-IGR) Branch

Program Description

Local Development-Intergovernmental Review (LD-IGR) is a mandated ongoing statewide effort focused primarily on avoiding, eliminating, or reducing to insignificance, potential adverse impacts of local development on the transportation system.  Caltrans is proud to share our expertise with other jurisdictions and assist them throughout their land use planning and decision-making processes, consistent with the requirements of the National Environmental Policy Act (NEPA), California Environmental Quality Act (CEQA), Streets and Highways Code, and numerous planning and zoning laws that affect our stewardship of the State Highway System. This Program is directed to use ‘best practices’ analysis methodologies that focus on:  improving person-capacity of our multi-modal transportation system; efficiently moving goods and services; and accurately describing transportation tradeoffs with other community values.  These values include: a sound business economy with housing near employment; a healthy ‘climate change sensitive’ environment, and equally safe access for both motorized and non-vehicular transportation users.


Californians have long insisted that their governments at all levels provide a high level of protection for the natural and built environment, while accommodating growth, as directed by the laws mentioned above, local agency mandates, and Presidential and Gubernatorial Executive Orders.  Caltrans began a formal IGR/CEQA program to respond to these challenges in 1983.  Deputy Directive 25-R1 elaborates on LD-IGR Program goals, objectives and collaborative responsibilities of each Caltrans functional Division. Currently the 12 districts annually review about 18,000 documents, and provide technical recommendations to development approval authorities in response to 6,000 of them. Since the passage of SB 45 in 1997, earlier and broader coordination, prior to formal CEQA consultations with our local partners, has increasingly been needed to insure that the development community contributes a fair share to infrastructure insufficiencies. Now, with the advent of recent climate change legislation, the role of the LD-IGR Program is expected to expand due to the increased emphasis on regional transportation plans, with traffic mitigation programs, that implement smart growth blueprints of sustainable community strategies.

Key Partners

Stakeholders include mostly federal, state and local NEPA/CEQA lead agencies, such as 480 cities, 58 counties, 44 regional transportation planning agencies, and various commissions, as well as federally recognized tribal governments.  However, the legislature, members of the public, and developers also directly seek and appreciate our special assistance.
