Summary

Coastal subsidence is occurring in Kapoho, Puna, Hawaii, with ongoing and historical episodic subsidence reported, posing risks to properties and infrastructure. The area is also prone to hurricane, tsunami, earthquake, and lava risks. The shoreline certification process is complicated due to frequent inundation, and issues with the Special Management Area include permitting new development, infrastructure improvements, and lot transfers. Mitigation options include raising or rebuilding seawalls, building new seawalls, and land exchange or acquisition. The report covers the Kapoho Beach Lots and Kapoho Vacationland Hawaii subdivisions, which were developed with little concern for geological risks, and have since experienced subsidence, including a reported 0.8 ft subsidence during the 1975 earthquake.
