Phase I Archaeological Survey
The Phase I archeological survey is the preliminary level of archaeological investigation
of an area affected by federal and state undertakings. The Phase I archaeological
survey provides an introductory level of archaeological surveillance in a project
area. If ground visibility is sufficient, the project area can be evaluated by pedestrian
survey at systematic intervals and observed for evidence of archaeological material.
If the ground visibility is deemed to be insufficient for the detection of potential
artifacts, then the area can be evaluated by shovel probes placed at systematic
intervals and subsequently screened for archeological material. However, if no archaeological
material is discovered by either survey technique, the Phase I survey can be the
final stage of the archaeological investigation. This is the most common level of
archaeological investigation and archaeological inquiry usually ends here.
