Meeting set to discuss dredging of Lahaina harbor, boat ramp

The Maui News – The state Department of Land and Natural Resources will hold a public meeting Monday to discuss maintenance dredging scheduled for October at the Lahaina Small Boat Harbor and Mala Boat Ramp.

The meeting will take place from 5 to 6:30 p.m. at the West Maui Senior Center. The event will be a venue for members of the public to comment on current shoaling conditions and question the department’s Division of Boating and Ocean Recreation staff.

The $1.2 million dredging project will deepen the now shallow harbor entrance channel, which is critical for safe passage of boat traffic in and out of the harbor, the department said. The harbor was last dredged in 2012.

On Monday, contractor American Marine Corp. will start preparing the dewatering site by installing things such as dust fencing for dredge materials at Mala and a full-depth silt curtain for work in the water.

In-water dredging at the boat ramp is scheduled to start Oct. 9 and finish Oct. 20. Dredging will follow in the harbor on Oct. 23 and finish by Dec. 29. Work will take place from 6:30 a.m. to 5 p.m. Monday through Thursday. The ramp and harbor entrance will be accessible throughout the construction period.

The project aims to remove and dispose of about 5,000 to 7,000 cubic yards of sediment from the harbor entrance channel and mooring, as well as 1,000 to 2,000 cubic yards of sediment from the boat ramp basin and entrance channel.

The dredging will be performed by barge-mounted equipment. Sediment will be removed by a closed bucket and deposited into a watertight bin on the barge or dump scow. Once full, the barge or dump scow will be towed to the ramp. The sediment will then be unloaded into watertight truck beds and transported to a designated stockpile site where berms will be constructed to contain the sediment and water.

No sediment or water will be allowed to discharge into the ocean. Once dry, the sediment will be hauled to an approved dumping site.
