APPROPRIATION / PHASE: Construction, General

BUSINESS PROGRAM: Flood and Coastal Storm Damage Reduction (with Mitigation of Federal Navigation Project)

AUTHORITY: House Committee Resolution dated 1 October 1986. The Delaware Bay Coastline, DE & NJ – Roosevelt Inlet-Lewes Beach, DE project was authorized for construction by Title I, Section 101 (a) (13) of WRDA 1999.

LOCATION: The project area is located along the Delaware Bay Coastline at Lewes Beach, Sussex County, Delaware.

DESCRIPTION: The plan proposed in the final feasibility report for the purposes of flood and coastal storm damage reduction and navigation mitigation is a 100-foot-wide berm at an elevation of +8.0 feet NAVD, and a dune at an elevation of +14.0 feet NAVD over a total project length of 1,400 feet. The selected plan includes dune grass, dune fencing and suitable advance beach fill and periodic nourishment every six years to ensure the integrity of the design. The plan also provides for reconstruction of the south jetty at Roosevelt Inlet. Initial placement of beachfill was completed September 2004 while dune crossovers, sand fence, and dune grass were completed in December 2004.  Artifacts were discovered on the beach during the dredging and subsequent beach placement operation. As a result, the District completed Phase 1 and 2 cultural investigations.
