Coastal Climate Adaptation Law

Rising seas, stronger storms, and shifting coastlines are placing new demands on the laws that govern shorelines, wetlands, and nearshore waters. Coastal climate adaptation law addresses how statutes, regulations, and local ordinances can help communities reduce risk, protect habitat, and plan for long-term change without abandoning the legal tools that already shape land and ocean use.

Sea Level Rise and the Coastal Legal Framework

Many U.S. coastal states manage development through a mix of coastal zone management acts, local zoning codes, building standards, and public trust doctrines. When sea levels rise, these separate authorities can pull in different directions. A zoning board may approve a shoreline project while a state coastal agency raises concerns about wetland loss. Adaptation law asks how these frameworks can be updated so that permit decisions account for projected flood zones, erosion rates, and habitat migration over decades rather than single construction cycles.

Legal Tools Communities Are Using

Practical adaptation options often appear in existing law before states write new statutes. Rolling easements, set-back requirements, buyout programs, and nature-based infrastructure standards each carry different legal questions about property rights, federal funding, and agency authority. Marine spatial planning can also place offshore wind, shipping lanes, and protected habitat on the same map, which helps agencies see where coastal hazards overlap with economic activity. ELI analyzes how these tools work in practice and where statutory gaps leave communities without clear guidance.

ELI's Work on Coastal Resilience

The Ocean Program connects adaptation law to its work on ocean and coastal planning, marine protected areas, and community engagement in the Arctic and Gulf regions. Staff attorneys review how federal and state agencies coordinate shoreline projects, assess whether environmental review processes address long-term climate risk, and publish guidance for practitioners through our publications collection. Related analysis also appears in the focus areas overview and through the program's Ocean Seminar Series.
