Supporting Healthy Coasts and Strong Coastal Communities

We support the shared vision of the coastal states, commonwealths and territories for the protection, conservation, responsible use and sustainable economic development of the nation’s coastal, ocean and Great Lakes resources.

163 Million Americans earn their livings and raise their families along U.S. coasts. By 2025, 75% of the US population will live along the coast.

More than one-half of the U.S. population lives within 50 miles of the coastline, an area which accounts for less than 20 percent of the nation's land area.

Welcome To The Coastal States Organization

The Coastal States Organization (CSO) was established in 1970 to represent the Governors of the nation’s thirty-five coastal states, commonwealths and territories on legislative and policy issues relating to the sound management of coastal, Great Lakes and ocean resources. Economically, socially and geographically, the states are as diverse as their individual coastlines, yet their commitment to common objectives in coastal and ocean management is what shapes CSO’s unique character. By speaking with “one voice” through CSO, states are more influential than by acting individually.


BUILDING COASTAL RESILIENCY: The State Coastal Zone Programs are America’s Greatest Asset When the Next Big Storm Hits

_________________________________________________________________________________________ All along America's coasts, communities are feeling the effects of sea level rise and more frequent dramatic weather events. These communities are responding with assistance from their respective State Coastal Program Agencies. In turn, these State Coastal Programs are working in partnership with the Coastal States Organization and the Nation Oceanic and Atmospheric Administration. Working in partnership, communities, their states, and the country are able to share best practices while comprehensively planning an integrated response to sea level rise.
