Sea Gate beaches experience no recovery following storms. Offshore volume changes are generally the sum of small vertical changes over wide areas. This may be real, may be an artifact of the DTM models, or may reflect survey accuracy problems. Fill material accumulating above and beyond the design template in the public beach area was successfully used as a borrow source for the hottest hot spot. This practice is being incorporated into future sand management programs, where applicable.
People tend to repeat earlier conclusions.
It is difficult to propose experimental solutions, such as a gravel beach, because of a lack of analytical tools for predicting behavior, and a lack of similar nearby construction. Many of the post-construction observations combined to produce a major hypotheses regarding sand movement. The East Bank Shoal, in combination with the shape of the harbor and the Hudson River produce significant tidal currents which in turn carve out the Coney Island Channel between Coney Island and the East Bank Shoal. Once sand is moved down profile into deeper water, it is removed by rapid tidal currents before beach recovery can occur. While the strong currents prevent beach recovery, swell energy reaching the site may also be insufficient to promote beach recovery.
