J.E. McAmis Wins West Coast Jetty Project

J.E. McAmis of Chico, CA has won contract from the U.S. Army Corps of Engineers, Portland District, to place more than 52,000 tons of new jetty stone on the North Jetty at the Mouth of the Columbia River.

The Mouth of the Columbia River North and South Jetties are situated along a stretch of ocean known as the “Graveyard of the Pacific.” This stretch of coast is known for unpredictable weather, strong currents and big seas which have claimed more than 2000 vessels and 700 lives at the entrance of the Columbia River alone.

The North Jetty was constructed between 1912 and 1917, with the last repairs to J.E. McAmis’ contract area occurring in 1939 and 1965. The outer portion of the jetty has experienced significant damage from winter storms resulting not only in loss of jetty length, but also to a narrowing and lowering of the jetty side slopes and crest section starting just offshore and extending to the current end of the jetty.

J.E. McAmis’ repair work includes reworking of existing stone up to 45 tons in size and placement of new jetty stones up to 27 tons in size. J.E. McAmis representative, Scott Vandegrift indicates that J.E. McAmis will utilize a combination of lattice boom cranes and large hydraulic excavators in completing work, which he says will be wrapped up by September of this year.
