|Coastal Erosion Map|
Coastal erosion is the loss of shoreline, beach and/or dune sediments and is caused by the lack of sediment delivered to the coast to balance the impacts ranging from man-made actions such as the damming of rivers, land subsidence from groundwater withdrawal, construction of seawalls, groins and jetties, diversion of rivers and streams, fast -moving motor craft and ship-generated wakes and many other factors to natural processes such as wave action from storms, tidal surges, wind, and loss of wetlands.
The average erosion rate for the 367 miles of Texas coast is 2.3 feet per year. Sixty-four percent of the Texas coast is eroding at an average rate of about 6 feet per year, with some locations losing more than 30 feet per year. FEMA estimates that every dollar spent on erosion control and mitigation to preserve wetlands and other natural ecosystems, will provide a return on average of four dollars in cost-savings for the future.
