Practical Approaches to Ocean and Coastal Decision-Making

Policy: USA – States

Background

While the federal government has regulatory authority for ocean waters between 3 and 200 nautical miles off shore, the states hold regulatory control in the important waters from 0 to 3 nautical miles1 off shore, where most ocean uses occur. State initiatives in coastal and marine spatial planning (CMSP) will be essential, as this is where the greatest need and conflicts occur. Through the Regional Planning Bodies, the states will determine how to implement CMSP in state and cross-boundary regional waters. In addition, CMSP decisions in federal waters will directly affect the states because all offshore industries must bring their products—such as fish, cargo, oil, and telecommunications cables—to shore.

State-level Action by The Nature Conservancy

Coastal states are taking many different approaches to CMSP, and their initiatives serve as models for future CMSP efforts at state, regional, and national levels. The Nature Conservancy is contributing scientific, technical, and policy expertise to assist these state efforts. The following are examples of the Conservancy’s activities to date.
