Alii Drive

The Alii Drive Shore Protection project is located along Alii Drive in the town of Kailua-Kona on the western coast of the island of Hawaii. This project was authorized under Section 14 of the Flood Control Act of 1946, as amended. The project construction was completed in January 2000. The total project cost was $360,000 (Federal: $234,000; non-Federal: $126,000).

The project provides protection and stabilization to the existing County-constructed 700-foot-long seawall along Alii Drive. The seawall structure was repaired by placing geotextile bags into the voids and then pumping the bags full of concrete. No concrete placement occurred at the Pa O Umi historical landmark or the existing storm drain outlet. The local sponsor is the County of Hawaii, Department of Public Works.
