Project update

January 12, 2018

Over the last few weeks, King County’s contractor for the Magnolia Conveyance Project finished excavating and installing shoring boxes at their site in Smith Cove Park. Over the next several months, crews will be working onsite in Smith Cove Park and on 32nd Avenue West to prepare to connect another pipe to the Magnolia Wet Weather Facility.  

Crews may work on Saturdays during approved construction hours.

Online open house 

We have launched an interactive online open house to share construction and schedule information with you. You can review the information and give input at your own convenience, any time of the day, at http://magnoliapipe.participate.online. If you have additional thoughts after you have reviewed the open house and have provided questions and comments, you can return to the site and start a new session.

Please feel free to share this information with your neighbors, and encourage them to participate.

Magnolia Wet Weather Storage FacilityThe Magnolia Wet Weather Storage Facility at Smith Cove is designed to store excess flows of stormwater and sewage. The facility’s 1.5 million-gallon underground storage tank will help keep sewage and stormwater out of Puget Sound during storms.

King County is Protecting our Waters

This project is part of King County’s Protecting our Waters program to prevent pollution caused by excess stormwater in the sewer system on rainy days.

Combined sewer overflows (CSOs) are relief points in older sewer systems that carry sewage and stormwater in the same pipe. When heavy rains fill the pipes, CSOs release sewage and stormwater into rivers, lakes, or Puget Sound.

King County and the City of Seattle are working together to control CSOs and keep sewage and stormwater out of local waterways.
