The U.S. Army Corps of Engineers will place about 55,000 cubic yards of sand at the Grays Harbor south jetty breach fill near Westport, Wash., beginning Nov. 14.
The sand placement is intended to protect against continuing erosion and the risk of a breach forming which could threaten the stability of the south jetty and federal navigation channel.
Sand will be placed in the most eroded portions of the spit, which will bring it back to a crest height of 35 feet. This will reinforce this area and provide necessary protection against a breach.
The Corps contracted Northwest Rock Inc., Aberdeen, Washington, to perform the work.
The sand must meet Corps gradation and marine sediment quality standards to nourish the threatened breach fill area.
Construction is planned during daylight hours, from 7 a.m. to 5 p.m., Monday through Friday and is expected to be finished by March 15.
