The Sammamish Plateau Diversion Project will create new wastewater infrastructure that will increase capacity to support the community in the East Lake Sammamish area. Currently, the project is in the exploration phase. Our project team is continuing to gather data through both desktop research and field surveys to help inform this project. 

Later this month, you may see crews surveying the right-of-way (ROW) on Northeast Inglewood Hill Road between East Lake Sammamish Parkway and 212th Avenue Northeast. During this work, surveyors will be in the public ROW marking utilities with paint and surveying locations. Additionally, crews will be accessing maintenance holes and catch basins in the roadway. We do not anticipate any traffic impacts during this work.

The work is scheduled to begin as soon as the week of April 14 and is expected to take up to five weeks to complete.  

What to Expect 

• Survey work taking place along the ROW on Northeast Inglewood Road between East Lake Sammamish Parkway and 212th Avenue Northeast.  

• Work hours between 7 a.m. and 3 p.m. Monday-Friday

• Work will take place up to five weeks.  

• Roads and sidewalks will remain open, and no traffic impacts are expected.  

CitySoil is a 1.5-acre demonstration farm tucked into a corner of King County’s South Treatment Plant in Renton. The farm’s purpose is to educate the public on the benefits of using recycled water, which flows through purple pipes, and Loop® biosolids as a sustainable way to grow food. South Treatment Plant takes in waste that goes down the drains of homes and businesses, cleans and disinfects it, and then turns some of it into recycled water that can be safely used to grow food. 

CitySoil produces about 5,000 pounds (2.5 tons) of food in partnership with the King County Wastewater Treatment Division, King Conservation District, DIRTCorps, and White Center Food Bank. The food bank supports more than 2,000 families every month. Access to fresh produce is a vital part of their operation.

White Center Food Bank helps the farm grow vegetable varieties used in recipes by the immigrant communities served by the food bank. Thai basil, daikon radishes, tomatillos, Roma variety tomatoes, and Kuri squash are just some of the crops grown at South Treatment Plant.  

On a typical farm, they might water plants with water from rivers that is processed for drinking. CitySoil Farm uses recycled water, leaving water in rivers and lakes for salmon and people.

If you would like to be part of the CitySoil success story, you can get involved as a volunteer. CitySoil Farm often needs volunteers for the growing season, from March to October. Here are ways you can pitch in: 

• Individual volunteers: Check our volunteer match page for current individual volunteer postings: https://www.volunteermatch.org/search/org675010.jsp 

• Groups (such as businesses, community groups, scout trips): We often need big groups for projects!
