by David A. Lau, US Army Corps of Engineers Pacific, Ocean Div, Fort Shafter, United States,



Document Type: Proceeding Paper

Part of: Coastal Engineering Practice

Abstract:

Laupahoehoe Harbor provides access to the fertile fishing grounds along the northeast or Hamakua coast of the island of Hawaii, Hawaii. The planning, design, and construction of Laupahoehoe Harbor featured: 1) a Local Cooperation Agreement which was one of the first in the nation to implement the cost sharing policies of the Water Resources Development Act of 1986; 2) the utilization of a 1:52 scale hydraulic model for the combined testing of harbor wave action and breakwater stability; 3) the use of a perimeter toe trench to increase stability to the breakwater toe; 4) the innovative design of a reinforced concrete pipe (RCP) rib cage breakwater; and 5) the efficient application of construction techniques resulting in the early completion of the project. Laupahoehoe Harbor was awarded the American Society of Civil Engineers. Hawaii Section, 1989 Outstanding Civil Engineering Achievement Award.
