Wetland Delineation


EnviroScience Biologist Performs Wetland Delineation

For over 35 years, EnviroScience biologists have provided wetland delineation services for clients across the U.S.

The Clean Water Act is a federal statute established to maintain and restore the chemical, physical, and biological integrity of the waters of the United States.

Section 404 of the Clean Water Act authorizes the U.S. Army Corps of Engineers (USACE) to regulate the discharge of dredged or fill material into the waters of the United States, including wetlands, streams, and other waters.

To define the location, size, and quality of the waters of the United States, the USACE established a delineation protocol. A wetland delineation is required for all projects that involve potential impacts on the waters of the United States.

EnviroScience has a team of respected wetland biologists with extensive delineation experience. Our expertise spans the country and includes most projects and industries.  A wetland delineation study includes:

  • A review of resource maps to identify potential resource areas on and adjacent to the site
  • A site visit to identify all water resources on and adjacent to the site
  • Wetland boundary flagging using survey-grade Global Positioning System (GPS)
  • Wetland classification
  • Photograph documentation

Streams and open-water features are also delineated and documented often. We document the delineation in a report in accordance with USACE reporting requirements. A digital map is produced in either AutoCAD or GIS (based on client preference) that accurately shows the resource boundaries and location. The report also includes all documentation and summaries often required for submittal to the USACE.
