South Padre Island Offshore Sand Source Study Phase 2

Summary

Three potential submerged sand resources were investigated to determine the volumes and quality of materials that can be used to nourish South Padre Island beaches. Geophysical and geotechnical investigations were conducted and a report prepared. The project identified one feasible offshore sand source location and minor supplemental sand sources associated with the navigation channel. The next steps are the preparation and submission to the USACE of a permit application for the sand source, and preparation of a preliminary design for a large-scale beach nourishment project.
