Cleveland Ave Sewer Replacement & Stormwater Separation

Map this project on the interactive project overview story map.


Replace old deteriorated sewers and build a new separate stormwater collection system to reduce Combined Sewer Overflow (CSO) discharge at Snohomish River Outfall (SRO) 4. $1 million of state grant funding is paying for nearly all of the new stormwater facilities.  

New collection sewers will lessen maintenance costs and improve system reliability; the new storm drainage system will lessen CSO discharges and provides opportunity for further system improvements in the future.

Everett is obligated to bring CSOs into regulatory compliance per an Agreed Order with Washington Department of Ecology. 

Project Description

This project is the remaining portion of the East Grand Project. The previous portion was constructed from 2014 to 2016 and was coordinated with the Tulalip Water Pipeline Segment 1 South for cost-efficiency and to minimize construction impacts to the neighborhood. The Cleveland Avenue project was originally launched in 2010 to undertake replacement of old deteriorated sewer collection pipes. In 2011 Ecology grant funding became available, and the project was expanded to include a separate stormwater collection system together with stormwater treatment to reduce CSO discharges at SRO4. The stormwater treatment units for the Cleveland Avenue Project will be modular wetlands and are somewhat different from those used for the East Grand Project. Modular wetlands do not have plants and will be inconspicuous.
