Phase I Cultural Resources Survey: An archaeological survey conducted to locate and identify all archaeological sites within a survey area, estimate size and boundaries of identified sites, evaluate potential site significance and recommend treatment of identified sites.
Phase II Cultural Resources Evaluation: Further investigates a specific site identified in the Phase I survey, including site-specific archival research, intensive surface survey, site mapping and possibly excavation of test units for the purpose of evaluating that site’s eligibility to the National Register of Historic Places.
Phase III Cultural Resources Mitigation: Typically involves data recovery of a National Register of Historic Places (NRHP) eligible site or other archaeologically important site that would be adversely impacted by a project. For NRHP-eligible architectural properties (buildings and structures), mitigation typically involves scaled drawings (elevations, planviews, cross-sections), large-format photographs (four inch by five inch negatives), and a detailed history of the building or structure.
Phase I Environmental Site Assessment (ESA): An investigation of a parcel of land and its associated structures for potential environmental issues.
Phase II Environemental Site Assessment (ESA): Provides a more detailed investigation, which involves chemical analysis of soil and groundwater to detect the presence of hazardous substances and/or petroleum hydrocarbons.
