About Cultural Resources

 

The Iowa DOT, often in cooperation with the Federal Highway Administration, works to identify and avoid historic properties as part of compliance with the National Historic Preservation Act (NHPA) of 1966 (as amended). This practice is often referred to as the Section 106 process.

Through Section 106 the Iowa DOT works with historic properties such as bridges, barns, archaeological sites, places of religious or cultural significance, historic cemeteries, and historic districts. Additionally, the Iowa DOT and the FHWA consult with various parties about historic properties.

The goal of Section 106 is to identify historic properties potentially affected by a project, assess potential impacts of the project and seek ways to avoid, minimize or mitigate any adverse effects on historic properties.

Programmatic agreement

The Iowa DOT, the Federal Highway Administration, the State Historic Preservation Officer and the Advisory Council on Historic Preservation have finalized their Programmatic Agreement that has established an updated process for compliance with the National Historic Preservation Act. This agreement was developed to establish an efficient and streamlined program for Section 106 compliance in Iowa.
