Soundview Dr NW Culvert Replacement

Description - Completed

Snohomish County replaced a culvert under Soundview Dr NW, in the Warm Beach area. The pre-existing culvert was deemed a fish-passage barrier. The new box culvert is designed to meet fish passage standards. This project connects Lake Martha Creek to a small Port Susan estuary that the Tulalip Tribes restored in 2019. Stream channel restoration was also completed. The project increases fish access to upstream habitat.


Construction began in August and finish in September of 2022

Traffic Impact

This project required a full 24/7 road closure during construction (see map).


The estimated cost for this culvert replacement was about $500,000 and was funded by Surface Water Utility funds.
