On September 8, 1900, the island was struck by a devastating hurricane. This event holds the record as the United States' deadliest natural disaster. The city was devastated, and an estimated 6,000 to 8,000 people on the island were killed. Following the storm, a 10-mile (16 km) long, 17 foot (5.2 m) high seawall was built to protect the city from floods and hurricane storm surges. A team of engineers including Henry Martyn Robert (Robert's Rules of Order) designed the plan to raise much of the existing city to a sufficient elevation behind a seawall so that confidence in the city could be maintained.
