USACE Repairs Union Slough Levee Along Snohomish River
The Union Slough Levee near Everett, Washington, is getting repairs starting this week, when U.S. Army Corps of Engineers’ officials will begin restoring approximately 1,245 feet of damage in four sections along the Snohomish River.
The project will cost approximately $1.1 million, USACE said.
Three of the repair sites will be near 28th Place Northeast and one will be adjacent to the Everett water treatment plant on 4th Street Southeast.
The Snohomish River exceeded flood stage in November 2017. The high river flows in the Snohomish River resulted in erosion of the riverward levee slope and toe, including loss of riprap and embankment material up to several feet above the water level. The damage reduced the levee to a 1-year level of protection.
The Union Slough Levee is approximately 41,000 feet long and protects much of Smith Island near the City of Everett including the City’s Water Pollution Control Facility, dozens of homes and local businesses, a marina and communication cables.
Once repaired, the levee will be restored to its pre-flood 30-year level of protection, according to USACE.
