Innovative Shore Protection Structures at Cap May Point, New Jersey

A demonstration project was installed at Cape May Point, New Jersey as part of the US Army Corps of Engineers National Shoreline Erosion Control Development and Demonstration Program. The purpose of the demonstration program is to evaluate prototype-scale “innovative” or “non-traditional” shoreline erosion control methods. The Cape May Point, New Jersey consisted of installing a linear prefabricated concrete submerged breakwater called the Beachsaver Reef and a linear prefabricated concrete sill called a Double-T across the seaward end of two adjacent groin compartments to abate shoreline erosion. This area is subject to both strong tidal currents and wave action and has a history of beach erosion. A monitoring plan has been implemented to evaluate the effectiveness of these two structures in retaining sand within the groin compartments, as well as retaining new beach fill sand that is to be placed in 2004. Project monitoring includes cross-shore beach profiles to document shoreline change and beach volume retention, scour and settlement measurements to assess structural stability, sediment samples to assess grains size changes, wave and current monitoring to measure wave/current modifications and aerial photography to document regional scale sediment, shoreline and duneline movements within the right groin compartments that compose the Cape May Point oceanfront.
