The Coastal States Organization represents the nation’s Coastal States, Territories, and Commonwealths on ocean, coastal, and Great Lakes resource issues.

While the coastal counties of the United States account for less than 10% of U.S. land area, they are home to 40% of the population – 125 million people.

Research from the Federal Emergency Management Agency has shown that every dollar spent on prehazard mitigation measures for insured real estate averts $4 in post-disaster recovery costs.

Coastal counties are national economic drivers, employing 54.6 million people and generating $7.9 trillion toward the nation’s GDP.

The resilience of our marine ecosystems and coastal communities depend on healthy marine species, including protected species such as whales, sea turtles, corals, and salmon.

Restore America’s Estuaries and the Coastal States Organization co-host The National Coastal and Estuarine Summit. We bring together the coastal restoration and management communities for integrated discussions to explore issues, solutions, and lessons learned in their work. The Summit explores cutting-edge issues in coastal restoration and management and highlights the latest research through interactive sessions, plenary speakers, and poster presentations. It invites a unique blend of people who are involved in policy, science, strategy, business, and on-the-ground restoration and management. The 2020 Summit will be in Providence, Rhode Island October 4-8, 2020.
