Archaeological excavations occur in three main phases: Survey, Site Testing & Evaluation, and Data Recovery
When there is a possibility of a project destroying or disturbing cultural remains, state and federal laws require that the work be monitored by an archaeologist to prevent damage to potential historic or prehistoric sites.
Some compliance requirements may call for evaluation of historic standing structures or engineering features.
The purpose of archaeological survey is to locate, delineate, and determine the eligibility status of archaeological sites for the National Register of Historic Places.
