CLASS III CULTURAL
Section 106 of the National Historic Preservation Act requires an assessment of impacts to all historic properties for projects with federal involvement. This so called "Class III" phase of this work typically involves teams of archaeologists walking the entire project area and recording identified archaeological sites and other cultural resources. Archaeological sites are then evaluated for significance according to legal criteria set out in the National Historic Preservation Act (NHPA) and National Register of Historic Places (NRHP). Additionally, ACR's geoarchaeologist evaluates the potential of subsurface archaeology within the project area and recommends subsurface testing where needed.

At ACR, we pride ourselves in our quick response time and tireless efforts in the field. A typical day conducting Class III survey involves hiking 8 to 10 miles per person, per day. We record and evaluate archeological and historic resources thoroughly and efficiently. Sites with subsurface potential are tested per SHPO and agency recommendations. Additionally, the subsurface archeological potential of each project area is assessed by a trained geoarcheologist. Based on our findings we make recommendations to the lead agency and clients regarding site eligibility, mitigation measures and possible solutions to allow project approval while protecting significant cultural sites.
