GRA provides a preliminary assessment of historic sensitivity to guide strategies and recommendations.
GRA is located within easy reach of several major archives of historic documents relating to the early history of the New York Metropolitan area, as well as those in New Jersey, Connecticut, and Pennsylvania. We conduct specialized historical research to contextualize archaeological finds and preserved surfaces. Our historic archeologists examine maps, deeds, surveys, and census records. This allows the team to determine how intact a site is. It also allows a determination of significance, by linking materials and landforms to historic structures and individuals.
