The U.S. Army Corps of Engineers and the lower Columbia River ports of Longview, Kalama, Woodland, Vancouver and Portland are conducting a joint environmental review to aid in developing a plan to ensure that the Lower Columbia River Federal Navigation Channel is maintained and operational for another 20 years. The Channel Maintenance Plan will include actions to manage dredged material while evaluating effects on the Lower Columbia environmental and socioeconomic resources. With this plan, the Corps, these Sponsor Ports, federal and state agencies, other ports and stakeholders will better understand what needs to be done—and do it well—to ensure a reliable deep-draft navigation channel.
The Corps and Sponsor Ports will evaluate environmental effects and plan alternatives (including ways to reduce dredging requirements) in an environmental impact statement and will select a dredged material management plan based on this analysis.
This stretch of the Columbia River, which extends from river mile 3 at the Mouth of the Columbia River to river mile 105.5, near Vancouver, Washington, is part of the Columbia & Lower Willamette Federal Navigation Channel Project. Nearly 55 million tons of cargo were transported on this stretch in 2015. A well-maintained channel supports regional and local jobs and provides significant and direct economic benefits.
