Advance Mitigation Program


The Caltrans Advance Mitigation Program (Program) was established by the Road Repair and Accountability Act of 2017 authorizing Caltrans to plan and implement advance mitigation solutions for its future transportation projects. This new business practice allows Caltrans to reduce delays by proactively obtaining environmental mitigation in advance of - rather than during - transportation projects. The Caltrans Division of Environmental Analysis (DEA) administers the Program and supports Caltrans Districts interested in planning and delivering advance mitigation projects.

The primary goal of the Program is to address longer-term future environmental mitigation needs resulting in improved environmental, economic and project delivery outcomes. By consolidating the forecasted mitigation needs of multiple future transportation projects, Caltrans can potentially provide strategically placed and environmentally sound replacement habitat and shorten project delivery timelines, resulting in both time and cost savings. Ultimately, the Program aims to help Caltrans meet conservation goals in addition to regulatory requirements.


  • Accelerate transportation project delivery
  • Improve environmental outcomes
  • Enhance communication with stakeholders and California Department of Fish & Wildlife
  • Ensure that the Program account is self-sustaining


Planning and implementation of the Program is a collaboration effort between Caltrans and its twelve Districts as well as the California Department of Fish and Wildlife. In addition, Caltrans regularly consults with agency partners such as the California State Water Resource Control Board, U.S. Army Corps of Engineers South Pacific Division, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, the California Coastal Commission, and National Marine Fisheries Service on how to apply the U.S. Department of Transportation Federal Highway Administration Eco-Logical vision on infrastructure development and ecosystem conservation integration in order to harmonize economic, environmental, and social needs and objectives.
