Mason Inlet Relocation Project

DRG prepared and submitted an environmental assessment and essential fish habitat report, as well as Section 404 and 401 permits for an inlet relocation in Wilmington, North Carolina.

Project Narrative:

Davey Resource Group, Inc. (DRG) conducted environmental studies related to the design and permitting of the relocation of Mason Inlet in New Hanover County, NC. In conjunction with Applied Technology & Management, Inc. (ATM), DRG prepared and submitted an Environmental Assessment that included a project alternatives analysis, Biological Assessment (Threatened and Endangered Species report), and an Essential Fish Habitat report. A CAMA Major Permit, as well as Section 404 and 401 Permits, were obtained for the inlet relocation, including the marsh area impacted by the widening of Mason's Creek.

In addition, DRG developed a tidal salt marsh restoration plan designed to offset project impacts to the marsh habitat. A former US Army Corps of Engineers (USACE) dredge disposal island located adjacent to the AIWW west of Figure Eight Island was identified for the wetland restoration. DRG conducted wetland delineations, vegetative mapping, and soil borings on the island to provide baseline information for the project design. DRG coordinated and supervised the installation of 81,000 coastal wetland plants within the constructed intertidal and high marsh habitats on the island. The tidal salt marsh restoration project has successfully restored high marsh, low marsh, and primary nursery habitats. DRG is currently working with New Hanover County and federal and state agency personnel to ensure permit compliance. DRG implemented a biological monitoring plan and a waterbird habitat management plan in accordance with US Fish & Wildlife Service (USFWS), National Marine Fisheries Service (NMFS), and USACE requirements.
