Area and Corridor Studies


"Our company does a significant amount of corridor studies for linear transportation projects and Envirosite has always done a fantastic job for every project. No matter the project size, Envirosite has always met or exceeded our needs."
Zach K. – Virginia

"My team uses Envirosite for large corridor projects that cover several thousand acres. The usability of the GIS-enabled data they provide coupled with the personal attention we receive is a win-win."
Rachel – Texas

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 2,000 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 in 8 steps:
  • 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
