A Class III survey is required for any undertaking (as defined in Section 106 of the National Historic Preservation Act) with federal involvement. A Class III survey typically includes a visual survey with archeological field personnel covering a project's total Area of Potential Effects (APE) and identifying, recording and evaluating sites in that location.
Prior to the initiation of cultural survey on-the-ground, many agencies require a Class I literature review to be conducted. This helps ensure that sites are evaluated in proper context and that field personnel are abreast of what potentially significant site types may be in the area. We conduct research of land patents, GLO records, state-held site and project inventories, key cultural contexts ofr the area, and other resources.
ACR can provide you with provide a trained geoarcheologist monitor, not just a technician. With our geoarchaeology credentials, we work directly with the BLM and other lead agencies to orient monitoring toward the most archaeologically sensitive areas and bypass monitoring where soils and sediments indicate low archeological potential.
Geoarcheology is the application of geologic and soil science techniques to answer archaeological questions. The discipline is especially valuable for determining the probability of subsurface archaeology in a given area. ACR's trained geoarchaeology personnel can help determine whether your project has potential for uncovering and disturbing archeological remains and how best to avoid them.
Historic trail studies are one of ACR's key area's of expertise. These significant cultural resources are often ephemeral and segments may be misidentified by archeologists lacking specific training and experience with these site types. ACR's team has over 40 years combined experience in historic trail segment identification and eligibility assessment. Let us help determine whether your project could potentially impact a historic trail and how best to mitigate potential effects.
ACR has been privileged to conduct research on many major historic battlefields in the western US. Our fired cartridge forensic studies and sub-meter accuracy artifact plots have helped reconstruct many major battles and skirmishes between Native American groups and the US military.
The visual impacts of your proposed project may be a consideration in the Federal approval process. ACR can determine with certainty whether the proposed project will have visual impacts and whether mitigation will be necessary.
When unexploded ordnance (UXO) remediation projects require archeological support or monitoring, ACR can provide archaeologists cross-trained as UXO Tech 1s. This saves you money by having the UXO Tech/ Archaeologist both recording artifacts and helping excavate ordnance.
