Wetlands
GMI’s wetland scientists have been actively delineating,
permitting, managing, and mitigating wetlands since the promulgation
of the Clean Water Act. Projects that affect wetlands, rivers,
swamps, bogs, and other types of water bodies can face complex
permitting requirements ranging from Section 404 of the Clean Water
Act to state and local regulations.
GMI’s wetland scientists have experience evaluating water regulations and negotiating with agencies in order to ensure successful completion of wetland related project. We use our technical skills, combined with environmental regulatory analysis and agency negotiations, to achieve client’s goals, regulatory compliance, and reduce overall project costs.
Our full range of Wetland and Waters of the U.S. services and expertise includes:
- Wetland and Waters of the U.S. Delineations
- Wetland Boundary Determinations
- Wetland Conditions and Inventory of Species
- GIS Mapping that Exceeds USACE Requirements
- Intermittent Stream Analysis and Determination
- Wetland Restoration
- Wetland and Waters Permitting
- Submission and Coordination for Section 404 Permits
- Agency Consultation and On-site Determination Assistance
- Wetland and Waters Mitigation
- Wetland Mitigation Plans
- Mitigation Monitoring
- Development of cost-effective mitigation strategies
- In-Lieu Fee Mitigation

Mountain Creek Wetland Delineation, Dallas, Texas
GMI conducted a delineation of jurisdictional waters of the U.S. based on methods described in the U.S. Army Corps of Engineers 1987 Wetlands Delineation Manual and 33 Code of Federal Regulations 328.3[e] within the site boundaries. GMI delineated the potential jurisdictional waters on an existing topographic map for permit submittal to the Corps. Deliverables included delineation methods and results, delineation map, completion of routine wetland determination data form, representative photographs of upland and jurisdictional sites, descriptions of the site and each jurisdictional area (i.e., soils, plant communities, historic land use, stream characteristics, and stream quality). Recommendations also included minimization plan to avoid a preconstruction notice submittal to the USACE.
Wetland Delineation, POD 4, Harbor View, Suffolk, Virginia
GMI conducted a wetlands delineation of approximately 40 acres. GMI collected information on soils, vegetation and groundwater in accordance with the procedures and criteria contained in U.S. Army Corps of Engineers Wetlands Delineation Manual. Principal emphasis will be on the northern section of the property. Specific deliverables included establishment of wetlands limits through placement of numbered field flags at wetland/upland boundary, field manuscript showing the location of delineation including the location of numbered flags, completed routine wetland determination data forms, and acquisition of concurrence with the field delineation by the Corps.
Wetland Delineation/Stream Verification, Marine Corps Base Camp Lejeune, North Carolina
GMI delineated wetland boundaries in the project area using digital orthophotography, ArcGIS, and field survey data. All wetlands boundaries were flagged and data was provided to USACE for a jurisdictional determination and permit. Field verification was conducted with USACE personnel and all permits for work were issued.
Wetland Delineation, Brookhaven Creek Pipeline, Norman, Oklahoma
GMI wetland biologists performed environmental surveys to delineate waters of the United States, including wetlands, along approximately 10,000 linear feet of an existing sewage pipeline adjacent/parallel to Brookhaven Creek iin Northwest Norman, Oklahoma. The delineation was conducted in accordance with U.S. Army Corps of Engineers 1987 Wetland Delineation Manual. The methodology incorporates a multiparametric approach requiring evidence of hydrophytic vegetation, hydric soils, and wetland hydrology for a positive wetland determination.
Wetlands Delineation, 2.8 Acre Site, Jackson/Tougaloo, Mississippi
GMI performed a site investigation to identify wetlands on a 2.8-acre potential communications tower site near Jackson, Mississippi. GMi performed a jurisdictional wetland delineation and flagged the wetland boundaries. GMI prepared a report and letter addressed to the U.S. Army Corps of Engineers requesting a jurisdictional determination. GMI also conducted a second onsite visit to meet with the Corps.
