ECONOMIC STATISTICS FOR NOAA
“Travel and tourism is the Nation’s largest employer
    and second largest contributor to the GDP,
generating over $700 billion annually. Beaches are
 the leading tourist destination, with coastal states
  earning 85 percent of all U.S. tourism revenues.
  Approximately 180 million people vacation and
       recreate along U.S. coasts every year.”

      STORM & TIDES PROJECT
• Promotes cooperation with Sea Grant and
  Coastal Zone Management Programs

• Involves local coastal residents who are trained
  professionals

• Provides high quality shoreline change and
  storm impact data at a very low cost

• Promotes public education and awareness of
  coastal vulnerability
