Cites University of Hawaii research finding that shoreline hardening on Oahu coasts causes beach narrowing, beach loss, amplified erosion on adjacent beaches, and reduced recreational and cultural access.

References Smithsonian Environmental Research Center study showing shoreline hardening significantly reduces populations of fish, crabs, and other aquatic life.

Notes a 2013 shoreline hardening project at Iroquois Point on Oahu killed nearly 90 percent of shoreline vegetation and caused amplified erosion along the adjacent coast.

Directs the Senate to transmit certified copies to the Secretary of the Navy, Commandant of the Marine Corps, Hawaii congressional delegation, Joint Base Pearl Harbor-Hickam leadership, and the Board of Land and Natural Resources Chairperson.
