USACE in Oregon: South Jetty Rehabilitation Program Set for This Fall

Oregon State Parks’ rangers joined the U.S. Army Corps of Engineers Portland District’s officials last month for a site visit to Fort Stevens State Park in the state of Oregon.

“We met with construction companies interested in the upcoming work to south jetty at the Mouth of the Columbia River. South jetty construction, scheduled to begin this fall, is the third and final phase to rebuild all three MCR jetties,” said USACE.

Both north and south jetties recently required critical repairs to ensure their continued function until the implementation of the Mouth of the Columbia River Jetty System Major Rehabilitation Project, which provides a long term repair and maintenance plan for the jetty system.

This plan is incorporated into the MCR Jetties Major Rehabilitation Evaluation Report. The last critical repairs occurred to North Jetty in 2015, South Jetty in 2007 and Jetty A in 1962, said USACE.

The jetties are regularly pounded by Pacific Ocean waves between 10 and 20 feet high with winter storms bringing extreme waves in excess of 30 feet. Over the years, many areas of each jetty were severely damaged by these waves. Increased storm activity and the loss of the shoaling sand upon which the jetties are built have taken a toll on the structural integrity of the jetties, USACE stated.

If a critical section of the jetties were breached during a large storm, sand could be deposited into the federal navigation channel potentially shutting down commercial shipping.

According to USACE, restoring the channel entrance would require expensive emergency repairs to the jetty and dredging to restore the channel to depth.

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
