South Magnolia CSO Control Project

• Provide a project update
• Present the design concept for the CSO control facility and get your feedback on landscape and architectural elements
• Talk about next steps

King County’s project team invites you to a community meeting to provide an update and answer your questions about a new underground storage tank in the Port of Seattle’s Terminal 91 West Yard. The tank will store combined sewer flows conveyed from the new gravity sewer pipeline from 32nd Avenue West. The team will address:

• Location and configuration of the storage tank and odor control/electrical facilities
• How the tank will be constructed
• How community input informed current design
• Next steps and opportunities to participate
