Thirty years have passed since the New Jersey Department of Environmental Protection (NJDEP) initially authorized the New Jersey Beach Profile Network (NJBPN) project in 1986. While there are multiple examples where extensive changes in shoreline configuration have occurred, the Hereford Inlet example was chosen because of the cause and effect relationship between extensive beach management projects and natural wildlife habitat generation that resulted from those projects. By 1991, beach deterioration in Stone Harbor on Seven-Mile Island in Cape May County had produced total loss of the upland dune and vegetated surface of Stone Harbor Point. Large intertidal shoals existed, but useful nesting habitat was limited (cover photo). Projects in 1998, 2003, 2011 and 2013 (following Hurricane Sandy) placed 4.819 million cubic yards of sand on the oceanfront beaches of Stone Harbor. Subsequent littoral transport of sand to the south produced the changes by 2016 (shown above). Similar examples exist at Corson’s Inlet, mid-beach in Ocean City, Brigantine, and at the south end of the Island Beach State Park in Ocean County. Northerly sand transport, derived from the material placed between Sea Bright and Long Branch in Monmouth County since 1995, has enhanced the Sandy Hook National Seashore by over 3.4 million cubic yards of sand. This report quantifies the changes, both positive and negative, observed at the 107 survey locations along the New Jersey Raritan Bay, Atlantic oceanfront, and lower Delaware Bay shorelines. Its goal is to provide a review of the past three decades and provide science-based guidance for future management decisions.
