Snohomish County is replacing a culvert under Soundview Dr NW, in the Warm Beach area. The existing culvert is deemed a fish-passage barrier. The new box culvert was designed to meet fish passage standards. This project will connect Lake Martha Creek to a small Port Susan estuary that the Tulalip Tribes restored in 2019. Stream channel restoration will also be completed. The project will increase fish access to upstream habitat.
Construction is expected to begin in August and finish in September. Construction crews will be working Monday – Friday during daylight hours.
This project requires a full 24/7 road closure during construction (see map).
The estimated cost for this culvert replacement is about $500,000 and will be funded by Surface Water Utility funds.
