Area and Corridor Studies

Our Area & Corridor Study reports are designed to support all large area and linear corridor projects that are greater than 1 mile — including non-contiguous projects. The reports access information from over 1,800 datasets and meet both the ASTM E1527-21 Phase I Standard requirements and EPA’s All Appropriate Inquiry (AAI) Rule.

Area & Corridor Study Reports include:

  • Database file (DBF) integration with your GIS system
  • User-specified search distances (choose ASTM standard search distances or customize search distances to meet your project needs)
  • Historical aerials, city directories, fire insurance maps and historical topographic maps for your area
  • Well data (USGS and state water wells) and public water supplies
  • FEMA Flood
  • Wetlands
  • Earthquake and seismic fault lines datasets
