126th Avenue Northeast water quality improvement


A Kirkland contractor expects to begin installation in early December on a stormwater storage and treatment system near Northeast 111th Place’s intersection with 126th Avenue Northeast. 

The system is designed to mitigate polluted stormwater runoff in the Forbes Creek watershed. 

The contractor, Northwest Cascade, Inc., expects to complete installation by the end of December.    

The project will improve the water quality in the Forbes Creek watershed, which supports the City Council’s goal of promoting Sustainable Environment and Dependable Infrastructure.  

Kirkland received a grant to build this project from the King County Department of Natural Resources, Wastewater Treatment Division.



  • Northwest Cascade will work eight-hour shifts between 7 a.m. and 6 p.m. The contractor expects to work from 7:30 a.m. to 4 p.m. 
  • People who are walking and bicycling will have access at all times. 
  • The project will remove two existing catch basins to direct stormwater into the planter box filter.
  • The contractor will maintain access for residents, businesses, mail, waste management, and emergency responders. 
  • Weather, material delays and other factors can change the schedule.
