The Kapaa Beach Shore Protection Project (SPP) is located on the east coast of the island of Kauai. The project was authorized in June 1975 under Section 103 of the River and Harbor Act of 1962, as amended. The local sponsor is the County of Kauai, Department of Public Works. The project is in the operations and maintenance phase.

The project was cost shared with the local sponsor and completed in September 1976. The shoreline at Kapaa fronts public property and extends northward from the Waikaea Canal to approximately 1,300 feet north of Moikeha Canal. A 25-foot-wide sandy beach extends along the 2,000-foot-long reach between the two canals. The project consists of the restoration of a 400-foot section of beach by placement of 6,000 cubic yards of sand, rehabilitation of a 150-foot section of Moikeha Groin, and 70 feet of revetment along the north bank of Moikeha Canal.

The project was turned over to the local sponsor upon construction completion to operate and maintain.  The Corps conducts annual inspections with the local sponsor to ensure the project is performing as intended.

Kapaa Beach Park offers recreational activities including surfing, walking, and biking.
