When we think of a pristine shoreline, we don’t usually picture man-made structures in the scene, but jetties and retaining walls are common sights along many waterways. Waves that continually crash against the shore release energy that can erode waterfront property. Bulkheads, retaining walls, and revetments are designed to protect shorelines by minimizing erosion. Over time, however, these structures may actually increase erosion by altering nature’s ability to replenish sensitive coastal areas.
