The ODOT Mitigation Inventory provides information on all of ODOT’s natural resource mitigation projects.  Individual project pages include compliance reports, permits, legal documents, maps, and photos.

ODOT strives to avoid, to the fullest extent practicable, any activity that adversely impacts natural resources during the design, construction, or maintenance of the state transportation system. ODOT takes appropriate action throughout the project development process to avoid, minimize, and mitigate impacts as required by federal, state, and local law. In the event that impacts to important natural resources are unavoidable, ODOT considers a wide variety of mitigation strategies, which always begins with evaluation of on-site mitigation opportunities within the project work area. Once the on-site (within the project area) resources are exhausted, the search for mitigation shifts to opportunities further from the project impact. Mitigation may include banking, habitat creation, restoration, and/or preservation of stream, wetland, and other natural resources.

Mitigation Signs


  ODOT denotes its mitigation areas with signs similar to the ones seen on the left.  These signs indicate the restrictions in place on mowing, spraying, etc.  In addition, they can display the year the site was established, and contact information for the District headquarters or Office of Environmental Services.
