Reconnaissance surveys are designed for the rapid examination of small project areas and are appropriate for use in many non-urban settings.  Reconnaissance surveys are not acceptable for urban environments. They allow for professional judgment in the number and placement of survey methods with the goal of assessing the presence or absence of sites in the most likely locations.

  • A reconnaissance survey may be undertaken if the project area is less than 1 acre in size, does not lie within the limits of any urban area as defined in the Phase I field standards, and does not include a site that has been determined eligible for nomination to the National Register or whose eligibility is undetermined.
  • For these projects, more than one sub-surface test (soil probe, auger, shovel test) must be judgmentally placed across the project area to assess evidence for the presence of a site and/or the extent and degree of disturbance.  A representative profile of the sub-surface tests must be recorded and presented in the report.  An overview photograph of the project area must be taken and presented in the report.
  • A reconnaissance survey may also be undertaken if the project area is between 1 and 10 acres in size, does not lie within the limits of any urban area as defined in the Phase I field standards, and does not include a site that has been determined eligible for nomination to the National Register or whose eligibility is undetermined.
  • For these projects, systematic sub-surface investigations at 30 m intervals (soil probe, auger, shovel test) must be placed across the area of direct surface or sub-surface impact to assess the evidence for the presence of a site and/or the extent and degree of disturbance.  Judgmental sub-surface investigations may be placed across the remainder of the Area of Potential Effect, with at least one sub-surface investigation placed in each acre of area.  A representative profile of the sub-surface tests must be recorded and presented in the report.  An overview photograph of the project area must be taken and presented in the report.
  • Any site(s) identified during a reconnaissance survey must be delineated as described in the Phase I field standards.
  • Any project greater than 10 acres in size must be examined by a Phase I survey.
