In support of environmental compliance, HRA’s historic preservation experts provide detailed documentation; conduct archival and field research; assess the significance, integrity, and eligibility of buildings and structures; and provide professional recommendations on the treatment of historic properties. Our architectural historians work closely with State Historic Preservation Offices (SHPOs), the National Park Service (NPS), municipalities, and local preservation boards to promote a broad, inclusive understanding of our shared history and its influence on the architectural evolution of our built environment.
