Project Completion



In 2019, Impact7G was approached by Stantec, Inc. and Invenergy, LLC to assist in wind farm development through identifying architectural and archaeological resources that could be affected by an energy project spanning over 100-square miles of the rural Iowa landscape.

Impact7G conducted targeted archaeological survey of turbine and associated infrastructure locations that fell under federal jurisdiction and were subject to Section 106 obligations. Impact7G identified numerous, previously unrecorded archaeological sites and evaluated each resource for National Register eligibility. All architectural properties in the viewshed were visited and evaluated for National Register eligibility. The Diamond Trail Wind Energy project was successfully built without affecting significant historic resources and the energy produced is currently aiding in electrifying homes and businesses in Iowa.
