This project will construct a network of stormwater pipes to collect runoff from streets and alleys and will remove pollutants from the runoff so it can be discharged to the Snohomish River. Removing stormwater from the combined sewer system will reduce the occurrence and severity of Combined Sewer Overflow (CSO) events into the Snohomish River and free up needed capacity at the wastewater treatment facility. This project will also provide stormwater treatment capacity for a future remodel/renovation of the east half of Jackson Park. Funding for a majority of the project costs is provided by a grant from Washington Department of Ecology. Overall project costs are approximately $1.5 million.
The project is generally located south of Jackson Park with new collection pipes being installed in Summit Avenue, 19th Street, Highland Avenue and East Marine View Drive (EMVD). Stormwater treatment units will be installed on a vacant City-owned site on the east side of EMVD. The construction work involves construction of approximately 2,200 linear feet of 12-inch to 24-inch-diameter storm drainage pipe, water quality treatment units and restoration.
