A detailed engineering analysis was performed for the proposed (since constructed) Aquatic Youth Center at Dockweiler Beach to specifically address the characteristics of beach morphology during the winter seasons as well as on a long-term basis, and the wave runup elevations and impact on the beach during extreme storm conditions. Therefore, the following work tasks were specifically addressed in this report; define the characteristics of the winter beach profile; characterize the long-term trend of the subject beach; analyze the storm return frequency; estimate the short-term eroded beach profiles under the severe storm conditions; computer wave runup elevations for the eroded beach profiles; assess the susceptibility of the proposed building against storm wave attack; and evaluate any adverse impacts to the adjacent beaches.

This coastal engineering assessment report described the site’s oceanographic conditions beach morphology particularly during the winter months, the storm-induced beach conditions and the resulting wave runup elevations. It then assessed the vulnerability of the proposed Aquatic Youth Center against wave attack, and the potential adverse impacts on coastal processes as a consequence of the proposed coastal development.
