In order to comply with Section 404 of the Clean Water Act, a wetland delineation is required to determine whether proposed projects will impact wetlands or other Waters of the United States. E&A’s environmental scientists perform wetland delineations, assess jurisdiction of features identified, and navigate the regulatory requirements for a project, including permitting, protective planning, and mitigation efforts.
-
Wetland Delineations: We canvas the site for wetlands and other Waters of the U.S. or Waters of the State, documenting our findings and provide an opinion of jurisdiction. As a part of the wetland delineation, we also correspond with the U.S. Fish and Wildlife Service and applicable state agencies regarding threatened or endangered species considerations.
-
Section 404 Permitting – Nationwide Permits: If a permit is required, we submit an application to the U.S. Army Corps of Engineers (USACE)
-
Section 404 Permitting – Individual Permits: For projects that will exceed 0.5 acres of wetlands impacts, Individual 404 permits are required. Though it is preferrable to avoid these due to time and resource constraints, E&A can prepare these extensive applications.
-
Wetland Mitigation Planning, Design, and Documentation: For project impacting over 0.1 acres of wetlands or 0.03 acres of channels, we design compensatory mitigation at the required replacement ratio and submit project information and As-Built documentation to the USACE.
-
Wetland Mitigation Monitoring: The USACE requires five years of annual monitoring after the construction of a mitigation site to ensure the wetlands are created to meet performance standards and are sustainable.
