ALA WAI CANAL DREDGING AND IMPROVEMENTS SCHEDULE CHANGES
(Honolulu) – In order to reduce nighttime impacts of dredging work in the Ala Wai Canal, DLNR is changing work hours, effective immediately.
The $21 million dollar, dredging and canal improvements project started last October and not only involves dredging accumulated silt and sediments from the Ala Wai but also includes the repair of two sections of wall.
Changing hours will not only reduce the impacts at night to the surrounding neighborhoods but will also enhance productivity of the project. New hours are as follows:
Monday-Friday 7:00am – 6:00pm
Saturday, Sunday, & State Holidays 9:00am – 10:00pm
The dredging depths varies between -12.0’ and -6.0’ mean lower low water, and the estimated total volume of dredging work and material is 186,000 cubic yards. This dredged material is being disposed at an EPA South Oahu Ocean Dredged Material Disposal Site.
The project contractor, Hawai‘i Harbors Constructors JV, will continue taking decibel measurements during dredging operations to ensure that noise levels are within those permitted.
The long-term benefits of this project include maintaining the ability of the canal to efficiently convey storm water flows to the ocean to reduce the risk of flooding and improving the aesthetics and use of the canal for recreational users. The work is scheduled to be completed by this late this year or in early 2021.
