Whatcom County Public Works River and Flood Division is working on these bank protection and levee repairs projects in 2022 and 2023.
The November 2021 flooding caused scouring and a major breach of the Marine Drive Levee. The major breach was repaired by the U.S. Army Corps of Engineers (USACE) in December 2021. The Flood Control Zone District (FCZD) is working on temporary repairs for three damaged sites. Repairs were completed in Summer 2022 to prepare the levee for the next flood season. Due to supply chain issues, the materials required for a permanent fix are unavailable. A larger repair project is scheduled for 2023.
Existing riprap protecting the Nooksack River bank upstream of Everson near the TransMountain pipeline crossing is damaged and requires stabilization measures. Design and permitting work is being fast-tracked. Construction will occur in 2023. The proposed improvements will incorporate habitat features
The left (west) abutment of the Glacier Creek bridge is currently protected by a levee built in 1962 after a damaging flood. The levee has two primary functions: preventing a major channel avulsion toward the narrower Gallup Creek bridge crossing and protecting the left abutment of the Glacier Creek bridge from erosion. The levee has been repaired occasionally over the last half century. ln November 2018, an approximately 100-foot long portion of the levee was partially eroded during a flood. The eroded portion has expanded to approximately 170 feet as a result of further damage sustained during the February 2020 and November 2021 floods. This bank is vulnerable to significant bank loss because of this damage. Work is underway to repair this damaged section of the levee with construction anticipated in 2023.
