CONGRESSIONAL DISTRICTS: NJ-2

APPROPRIATION / PHASE: Construction, General

BUSINESS PROGRAM: Flood and Coastal Storm Damage Reduction

AUTHORITY:  WRDA 1999, Section 101(a)(26).

LOCATION:  The study area is a 12-mile portion of the New Jersey Coastline from Townsends Inlet to Cape May Inlet.

DESCRIPTION: The recommended plan for flood and coastal storm damage reduction includes: (1) 4.3 miles of beach fill with a berm width of 150-feet and a dune crest at +14.75 feet NAVD, with periodic nourishment at 3 year intervals; (2) 2.2 miles of seawall construction along the Townsends Inlet frontage of Avalon and the Hereford Inlet frontage of North Wildwood; (3) ecosystem restoration of approximately 116 acres of natural barrier island habitat at Stone Harbor Point including beach fill and dune construction. The restoration includes the planting of approximately 56 acres of bayberry and red cedar roosting habitat. 

STATUS: The beachfill portion of the project was initially constructed in 2002 and the Townsends Inlet and Hereford Inlet seawalls were initially completed in 2009. The dune and beachfill project was renourished/repaired in 2011, 2013, 2017 and 2019. The Hereford Seawall was initially constructed in 2 phases with Phase 1 completed in 2007 and Phase 2 completed in 2010. Repairs were completed to the Hereford Seawall in 2014 and 2021. The Townsends Seawall was initially constructed in 2006. The next periodic nourishment cycle is scheduled for Fiscal Year 2022 but is dependent on receipt of adequate funds. Sand for this nourishment cycle for both Avalon and Stone Harbor will come from Townsends Inlet
