• Mitigation
  • Delineation
  • Construction/Restoration/Enhancement
  • Clean Water Act Section 404 Permits
  • Water Quality Treatment Design

Our staff has performed numerous wetlands consultations throughout several U.S. Army Corps of Engineers (COE) districts, is recognized by the COE as preferred consultants, and is formally trained in COE-approved wetlands delineation techniques, construction design, and Section 404 permitting regulations.

Key wetland experience includes:

  • Wetland Mitigation, Monitoring, and Construction Design
  • Wetland Delineation
  • Section 404 Permitting and Compliance
  • Wetland Impact Assessment
  • Wetland Water Treatment Design
  • Wetland and Biological Sampling for Contamination Source Mapping
EDM’s wetlands experience also includes the development of wetland mitigation banking programs, which encompass:

  • Coordinating with Multi-agency Review
  • Drafting the COE Regulated Banking Instrument
  • Designing Wetland Construction Plans
  • Implementing Wetland Monitoring Plans
  • Evaluating Existing and Created Wetlands for Mitigation Function and Value
  • Completing Section 404 Permit Applications
  • Delineating Wetlands for Potential Mitigation
A successful mitigation program is effectively designed to compensate for wetlands lost due to construction activities pursuant to the ‘no net loss of wetlands’ compliance defined under the Clean Water Act. EDM’s success in wetlands mitigation and permitting can be attributed to proactive communications with the COE and the interagency review team, typically consisting of the Environmental Protection Agency, U.S. Fish & Wildlife Service, Natural Resource Conservation Service, and State Wildlife Agencies.
