The primary goal of beach nourishment is to protect infrastructure such as highways, utilities, buildings, and drainage systems from damage due to storm surge and overwash. By widening the existing beaches through nourishment, we are creating a larger buffer between the Atlantic Ocean and the infrastructure, which ultimately provides it with a higher level of protection and stronger defense against storms.
It’s important to note that shoreline erosion following a beach nourishment project is expected and does not mean the project was unsuccessful. The additional sand that was placed on the shoreline during beach nourishment serves as a buffer that prevents the roads, buildings, utilities, etc. from bearing the brunt of wave action and storm surge. Sand that is placed on the beach during beach nourishment is expected to erode over time in order to achieve the primary goal of protecting the infrastructure while also serving a number of other purposes like providing wildlife habitat, increasing tourism, providing recreational resources for residents and visitors, and boosting the local economy.
