The comprehensive archaeological, architectural, and historic preservation services that RGA provides to its diverse client base are performed in accordance with federal, state, and municipal laws designed to protect the natural and cultural environment. Section 106 of the National Historic Preservation Act of 1966 is the catalyst for these services when a project is a direct federal undertaking (National Park Service, Department of Agriculture, US Navy, US Coast Guard, etc.), requires a federal agency approval or permit prior to construction (such as from the Federal Energy Regulatory Commission, US Army Corps of Engineers, etc.), or receives funds from a federal agency (such as the U.S. Department of Transportation, Department of Homeland Security, etc.). The types of projects that require Section 106 compliance vary widely and generally fall into one of several broad market sectors such as transportation, public utilities (water and sewer), private development, direct government contracts, energy, and telecommunications. Other federally funded or permitted project types that are less common can include new construction of or improvements to post offices, banks, and housing projects that receive Housing and Urban Development funding. State and municipal laws also mandate pre-construction consideration of project effects on cultural resources under certain environmental thresholds or for specific management areas, parks, and open space, often in a manner generally consistent with Section 106 guidelines. These projects include state funded initiatives as well as privately funded residential, recreational, and commercial developments that have no federal oversight.
