Division of Environmental Analysis

Share via:


The Division of Environmental Analysis (DEA) administers Caltrans' responsibilities under federal and state environmental law. The Program develops and maintains Caltrans environmental standards, policies, procedures, and practices that are implemented by the Department's 12 District Environmental Branches. Program staff work with the districts to identify and assess the effects of Caltrans projects on the state's natural and cultural environments, and identify ways to avoid or mitigate those effects.

DEA acts as the Department compliance lead and assists the Districts and our transportation partners in:

  • Complying with state and federal environmental laws;
  • Encouraging the public to participate in the environmental evaluation process;
  • Determining the environmental consequences of our activities;
  • Proposing prudent, feasible and cost effective strategies and alternatives to avoid or minimize adverse impacts of the Department's activities, and;
  • Ensuring the mitigation selected is appropriate.
In response to enactment of the National Environmental Policy Act (NEPA), in 1969, and the California Environmental Quality Act (CEQA), in 1973, Caltrans formally initiated an environmental function. Subsequently, in response to the passage of a host of environmentally-related lawsand regulations and heightened public support for the environment, the Program has grown to become a substantive and inseparable part of Caltrans' planning, development, construction, operation and maintenance efforts.

DEA Leadership

DEA is headquartered in Sacramento, though each of the twelve district offices, located throughout the state. The Program, administratively under the Deputy Director for Project Delivery, is headed by a Program Chief who also serves as the Agency Preservation Officer. DEA has a highly-trained, professional staff of planners, engineers and environmental specialists who work with the District Environmental Branches to help their staff and project managers with the environmental project process.
