Construction on Five Culvert & Drainage Projects Begin in Snohomish County 


Some full and partial road closures will be required during construction


EVERETT, Wash., June 27, 2022 – Each year, Snohomish County Surface Water Management and Public Works partner to replace multiple fish-barrier culverts with new fish-passage structures under county roads. This year, five culverts and a drainage pipe will be replaced. Some projects will require partial or full road closures during the summer months while work is completed. 


Jim Creek Rd – Trafton Area

A culvert replacement in the 19900 block of Jim Creek Rd will be completed this year. Last year an under-sized culvert was replaced with a larger, fish-passage steel arch culvert. The road has been in an alternating single-lane road configuration since last year’s work was wrapped up in October. Construction is expected to occur in late June through September to finish work in the stream channel and restore the two-way permanent road configuration. During construction, the road will continue as an alternating one-way with flaggers present while work is performed. Crews will be working during daylight hours Monday through Friday with potential weekend work. 


184th Pl SE – Bothell Area

One culvert will be replaced under 184th Pl SE in the 2800 block. Construction is expected to begin June 30 and last for two months. Crews will be working Monday through Friday during daylight hours. The road will be closed around the clock at approximately 2822 184th Pl SE from June 30 through August 31 with a detour route in place.


280th St NE – Bryant Area

Two culverts will be replaced under 280th St NE, west of 3rd Ave NE in the Arlington area. Construction is expected to begin on July 1 and end in mid-September. Crews will be working Monday through Friday during daylight hours. The road will be reduced to a single lane, around the clock, for the duration of construction. 


156th St SE – Cathcart Area

A failing drainage pipe that crosses 156th St SE in the 8500 block will be replaced with a larger capacity pipe. Construction is expected to occur in August and last for two weeks. Crews will be working Monday through Thursday during daylight hours. The road will be closed around the clock for two weeks with a detour route in place.


Soundview Dr NW – Warm Beach Area

A culvert under Soundview Dr NW will be replaced, connecting Lake Martha Creek to a small Port Susan estuary that the Tulalip Tribes restored in 2019. Stream channel restoration will be completed. The project will increase fish access to upstream habitat that will eventually extend to Lake Martha with five additional culvert replacements currently in design. Construction of the Soundview Dr NW project is expected to begin in August and finish in September. Crews will be working Monday through Friday during daylight hours. The road will be closed around the clock at approximately 19612 Soundview Dr during construction.


Snohomish County Surface Water Management and Public Works’ culvert and drainage improvement program typically replaces three to four fish-barrier culverts each year, depending on size and funding availability. Failing drainage infrastructure is also replaced or repaired to reduce flooding potential. Many culverts were built before fish passage requirements were in effect and others became barriers over time through deterioration or changes in flow. Replacing fish-barrier culverts can increase habitat that is an important component of protecting and restoring fish populations in Snohomish County.
