Historic Preservation

HRA’s historic preservation specialists work with clients from federal, state, and local entities as well as private organizations. HRA architectural historians and historians have worked with LEED-certified architects to demonstrate the contribution historic resources make to a sustainable environment, including restoration, rehabilitation, and preservation of historic resources to the Secretary of the Interior’s Standards for the Treatment of Historic Properties.

Our specialists meet the Secretary of the Interior’s Professional Qualification Standards and have extensive experience in compliance with the National Historic Preservation Act (NHPA, Section 106), National Environmental Policy Act (NEPA), state environmental policies and legislation regarding historic properties (SEPA, CEQA, etc.), and local policies and ordinances.
