Is a Transect Report the same as a Phase I ESA?
No, Transect is not a hazardous materials database report.
A Transect Report is not the same as a Phase I ESA; however, the two tools work together to provide a full picture of site risk. A Phase I ESA (per ASTM E1527-13) focuses specifically on hazardous contamination and environmental liability. Transect specializes in natural resource risk, vetting projects against dozens of state and federal regulations such as the Clean Water Act and the Endangered Species Act.
While a Transect Report is not a substitute for a Phase I, it provides early visibility into many of the same critical datasets—including underground storage tanks and voluntary cleanup sites—while simultaneously identifying constraints like wetlands, protected species, and historic resources.
Most developers use Transect to understand and visualize a site’s potential bottlenecks within minutes. When you're ready to move forward with a project, you don't need to find a new vendor—you can seamlessly order a Phase I ESA through our built-in Marketplace, keeping all your site data and professional services in one centralized platform.
