Updates from the Sammamish Plateau Diversion Project

Updates from the Sammamish Plateau Diversion Project

As the days get longer and we approach spring, our project team continues working on project options. This exploration phase takes longer when King County builds new sewer facilities than when we replace existing pipes, equipment, and facilities. It’s a lot like remodeling a home compared with building a new one.

Finding the right location for new facilities presents unique challenges in areas like the Sammamish Plateau neighborhood. Teams need to consider residential and business development, the natural environment, roadways and traffic, utilities, and more. To consider all these unique needs, you may see our project team this spring and summer conducting more survey work.

We appreciate the community bearing with us during this time! We look forward to sharing what we have learned later this year.  

During these quiet periods, it’s also a great time for us to get to know you and what you need to stay updated on our project. By understanding your needs through our survey (linked below), we can serve you better during the design and construction phases of this project.

The survey should only take about 10 minutes to complete. We have two separate surveys: one for community members and another for local businesses. If you are both a community member and a local business owner who may be impacted by future construction, we encourage you to complete both surveys. 

This area was once an auto-wrecking yard and a soup factory. Now, it has been transformed into a thriving habitat, with large trees preserved for wildlife and a Native Growth Protection Area. Sapsucker Creek runs through the north forested area. Named after the red-breasted sapsucker, it attracts woodpeckers that make distinctive holes in the trees to tap tree sap. Migrating hummingbirds use this sap for energy before flowers bloom in the spring.

Birdwatching in the Brightwater trails area is more than spotting feathered species. It's an adventure where you can wander with nature’s rhythms, from changing seasons to migrating birds. Open daily from dawn to dusk, Brightwater is perfect for solo birdwatchers, peaceful walks, or family outings. Grab your binoculars and explore its birdwatching wonders.
