Between March 1 and 5, 2021, Brockington and Associates, Inc. (Brockington) completed a Phase I cultural resources survey for the proposed Gravelly Creek Substation located in Jackson County, Georgia (Figures 1 and 2). The 39-acre substation tract is located on either side of Nunn Road northeast of Commerce. One standing house is located on the north side of the road near the center of the tract. Our cultural resources survey was carried out for Georgia Power Company (GPC) ahead of proposed construction of a substation on the tract. Our survey included a literature review to document all known resources as well as archaeological and architectural field investigations to identify any new resources. Our archaeological survey area is defined as the 39-acre proposed substation property. Our architectural survey area includes the project tract as well as an additional radius of 0.25 mile (0.4 kilometer [km]) to account for possible visual effects. Our primary goal was to determine if the proposed project will impact cultural resources that are eligible for the National Register of Historic Places (NRHP). This letter report includes a description of our methods, the results of our background research and field investigations, and our recommendations for the proposed project. Though this is a due diligence project, all activities described herein have been carried out in accordance with the stipulations of Section 106 of the National Historic Preservation Act (NHPA) (per 36 CFR Part 800, as amended through 2016) and the Advisory Council on Historic Preservation (ACHP) revised 36 CFR Part 800 Regulations. We also followed current guidelines established by the Georgia Council of Professional Archaeologists (GCPA 2019) and the Georgia Department of Natural Resources (GDNR) Historic Preservation Division (HPD) (2017) as well as other pertinent state and federal guidelines. We evaluated all cultural resources identified during this investigation for eligibility for inclusion in the NRHP based on criteria set forth by 36 CFR Part 60.4. Supervising personnel for this survey meet or exceed the Secretary of Interior’s Professional Qualification Standards in accordance with 36 CFR Part 61.
