Kaanapali Beach has been negatively impacted by chronic and extreme seasonal erosion over the past four decades. Sand loss is expected to continue and even accelerate with sea level rise, the state Department of Land and Natural Resources said Tuesday in its news release announcing the meeting.

The DLNR Office of Conservation and Coastal Lands will be holding the informational meeting on the sand replenishment project developed by the state and the Ka’anapali Operations Association Inc. Restoration is proposed for the section of beach between Hanakao’o Beach Park and Hanaka’o’o Point, and berm enhancement is proposed for the beach between Hanaka’o’o Point and Pu’u Keka’a.

A draft environmental impact statement was published Aug. 23 with the triggers being the use of state land and funds and land in a conservation district and in a shoreline area. The comment period is open until Oct. 7.

Since 1990, the Ka’anapali Ali’i, Sheraton Maui Resort & Spa and Ka’anapali Beach Hotel have been threatened by erosion events. Beach walks have been damaged and removed and acres of vegetation and trees swallowed up by the sea, the draft EIS said.

Mitigation efforts have included the use of sandbags, sand mattresses and steel road plates. Plans for beach enhancement began in 2006.

The draft EIS says that berm enhancement would raise the elevation of the dry beach by 3.5 feet. The approximately 75,000 cubic yards of sand needed for the proposed project would be recovered from an 8.5-acre sand deposit, located approximately 150 feet offshore of Pu’u Keka’a in 28 to 56 feet water depth.

The proposed sand recovery method consists of a moored crane barge equipped with a clamshell bucket, the draft EIS said. Barges would rotate between the sand deposit and two off-loading sites, where the barges would be moored to an elevated trestle or floating bridge to shore. The sand would be transferred to shore along the trestle or bridge system.

Land-based equipment would transfer sand from the shoreline to the placement area to be spread along the shore and berm enhancement areas, the draft EIS said.

The work is expected to take two months between October and December 2021, the draft EIS said. The cost is estimated at between $9 million and $13 million.
