HRA worked with the Avista Corporation to produce a Historic Properties Management Plan for the Spokane River Hydroelectric Project in northeastern Washington and northern Idaho. HRA also contributed to inventory and evaluation reports for this project and served as an expert witness in a Federal Energy Regulatory Commission administrative hearing. Throughout the project, HRA assisted Avista in consultation with the affected Tribes, federal and state agencies, and State Historic Preservation Offices participating in the Cultural Resource Work Group. HRA is currently participating in the implementation of the license.
