What a seawall might look like

Placement of fixed engineering structures, typically rock, wood timbers, or concrete, on or along the shoreline to reduce coastal erosion and protect coastal infrastructure. Armoring structures include seawalls, revetments, bulkheads and riprap.

This article is part of a series on Shoreline Structures looking at types of structures commonly built along shorelines, and the policies, laws, and regulations which can affect where and under what conditions they are built.

For information about laws, policies and conditions impacting shoreline structures in a specific state, please visit Surfrider's State of the Beach report to find the State Report for that state, and click on the "Shoreline Structures" indicator link.
