U.S. Army Corps of Engineers Disturbance Mapping Project

Columbia River Basin, Eastern Washington

The U.S. Army Corps of Engineers (USACE) must comply with Section 106 of the National Historic Preservation Act, which requires review and evaluation of all federal undertakings with potential to affect historic properties. The USACE conducts many activities that likely occur on previously disturbed lands.

Our GIS team developed a comprehensive database and GIS mapping system to depict areas of earth disturbance related to dam construction and related facilities, including geo-referencing scanned historical documents and digitizing archaeological resources. The final product was a robust GIS-linked Access database and a companion bound hard copy map atlas. To better facilitate the use of the database, our staff prepared hands-on training to demonstrate applications of the digital data as it relates to current and/or on-going projects.
