In 1957, to restore and stabilize the beach of Sherwood Island State Park, sand was pumped to the shore from an offshore borrow area by a hydraulic pipeline dredge. In addition, two training walls were constructed to confine the inlet at the east end updrift and a groin built at the west end of the park. The entire beach was widened and raised, and in addition, an extra amount of snad was placed on Sherwood Point to act as a feeder beach. The material from the borrow area proved to be suitable beach fill. In 1962, surveys showed that while the actual net loss of sand from the project area was slight, losses from the tidal zone in the updrift and central parts of the area were major. These losses indicate that maintenance fill is now required and that the construction of several short groins west of Sherwood Point downdrift may be desirable. Data, in graphic form, show comparative profiles of the area, changes in shoreline, and composite size-distribution curves for sand samples. Tables show quantitative volume changes and sand sample data. Initial and annual cost figures are given.
