Mason Inlet

Location: Wilmington, NC

Project Overview:
LMG conducted environmental studies related to the design and permitting of the relocation of Mason Inlet.

LMG conducted environmental studies related to the design and permitting of the relocation of Mason Inlet. In conjunction with Applied Technology & Management, Inc. (ATM), LMG 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.

Section 404 and 401 Permits were obtained for the marsh area impacted by the widening of Mason’s Creek. In addition, LMG developed a tidal salt marsh restoration plan designed to offset any potential adverse impacts to the marsh habitat. A former COE dredge disposal island located adjacent to the AIWW west of Figure Eight was identified for wetland restoration. LMG conducted wetland delineations, vegetative mapping, and soil borings on the island to provide baseline information for the project design. The remaining compensatory mitigation requirements were achieved through the preservation of 19 acres of coastal marsh habitat east of the spoil island.

The tidal salt marsh restoration project will restore high marsh, low marsh, and primary nursery habitats. LMG is currently working with the County and federal and state agency personnel to ensure permit compliance. Our staff has completed a biological monitoring plan and a waterbird habitat management plan in accordance with US Fish & Wildlife Service (USFWS), National Marine Fisheries Service (NMFS), and US Army Corps of Engineers (USACE) requirements. LMG continues to maintain the waterbird nesting area and monitor various ecological parameters in tidal marsh, intertidal sand flat, and intertidal surf zone habitats within and adjacent to the relocated inlet.
