The Galveston Seawall is a seawall in Galveston, Texas, USA that was built after the Galveston Hurricane of 1900 for protection from future hurricanes. Construction began in September, 1902, and the initial segment was completed on July 29, 1904. From 1904 to 1963, the seawall was extended from 3.3 miles (5.3 km) to over 10 miles (16 km) long.
Reporting in the aftermath of the 1983 Hurricane Alicia, the Corps of Engineers estimated that $100 million in damage was avoided because of the seawall. On September 13, 2008 Hurricane Ike's storm surge and large waves over-topped the seawall. As a result, a commission was established by the Texas Governor following the hurricane to investigate preparing for and mitigating future disasters.
A proposal has been put forth to build an "Ike Dike," a massive levee system which would protect the Galveston Bay, and the important industrial facilities which line the coast and the ship channel, from a future, potentially more destructive storm. The proposal has gained widespread support from a variety of business interests. As of 2009[update] it is currently only at the conceptual stage. Further proposals for a layered network of smaller, local levees and natural protections have been put forward by the SSPEED Center at Rice University and the University of Houston. These proposals include a surge gate at the mouth of the Houston Ship Channel connecting adjacent high ground near the Hartman Bridge, and hard protections for the west shore of Galveston Bay and around the densely developed east end of Galveston Island. Also included is the proposed lower coastal Lone Star Coastal National Recreation Area.
Texas F.M. 3005 is known as Seawall Boulevard where it runs along the seawall. The sidewalk adjacent to Seawall Boulevard on top of the seawall is claimed to be the longest continuous sidewalk in the world at 10.3 miles (16.6 km) long.
Many miles of the seawall are painted with murals called "wall art". These huge murals are painted by children and depict underwater life. The art is meant to make the seawall more interesting to visitors.
