Final Mojave Desert Ecoregion Section Regional Advance Mitigation Needs Assessment Available

Caltrans Advance Mitigation Program (“AMP”) is pleased to announce that the Mojave Desert Ecoregion Section Regional Advance Mitigation Needs Assessment (“RAMNA”) and its Appendices are final and are posted under “Resources” on the AMP web page, below.  The RAMNA establishes Caltrans’ need for advance mitigation for the Mojave Desert Ecoregion Section for the fiscal years 2017/2018 to 2026/2027.  Looking forward, consistent with Program Guidelines (PDF), Caltrans District 8 will continue to the next step of the AMP planning process and begin advance mitigation project scoping to meet the mitigation need for future transportation projects for the Mojave Desert Ecoregion Section.  An advance mitigation project scope will consist of one or more of the SHC § 800.6(a) activities that is authorized for reimbursement by Caltrans’ Advance Mitigation Account.

Process Agreement Signed

The Master Process Agreement for Planning and Developing Advance Mitigation throughout California for the California Department of Transportation Advance Mitigation Program (“Process Agreement”) received its finalizing signature on January 24, 2020.  Natural resource regulatory agency signatories are CDFW, the State Water Board, LA Corps District, Sacramento Corps District, SF Corps District, the EPA, USFWS, NMFS, and the Coastal Commission. The Process Agreement establishes a mutually agreed-upon process between Caltrans and the natural resource regulatory agencies for managing and reducing some of risks associated with Caltrans early investments in advance mitigation planning and advance mitigation project delivery and improving the probability that the mitigation will be approved for use.  A key part of the agreed upon process is that the resource agencies will review a new planning document that analyzes Caltrans need for compensatory mitigation in a specified area. The new planning document is called a Regional Advance Mitigation Needs Assessment.  The document is available upon request from

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 BoardU.S. Army Corps of Engineers South Pacific DivisionU.S. Environmental Protection AgencyU.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.
