Hawaiʻi Coastal Erosion Management Plan 

Studies conducted at the University of Hawaii show that hardening the shoreline of Oahu where there is chronic coastal erosion causes beach narrowing and beach loss. Researchers have found that on Oahu 10.7 miles of beach has been narrowed by shoreline hardening and 6.4 miles has been lost. This is ~24% of the 71.6 miles of originally sandy shoreline on Oahu. The Coastal Erosion Management Plan (COEMAP) provides a framework for community discussion and assessment of coastal erosion and beach loss in Hawaii. The objective of COEMAP, and the public dialogue it seeks to foster, is to outline socioeconomic and technical mechanisms for conserving and restoring Hawaii’s beaches in a framework of mitigating erosion impacts and reducing exposure to coastal hazards for future generations.
