Inglewood Hill Drainage Trunkline and Non-motorized Improvement Project




The contractor is currently working on punchlist items to complete the project.  We anticipate end of May 2017 for project completion.


The City awarded the $4.5M construction contract to Marshbank Construction.  Construction for the project began on July 5, 2016 and is expected to continue through February 2017.  

Project Summary

The project includes the construction of stormwater conveyance, water quality facilities, sidewalks and roadway resurfacing. The goals of this project are to address existing drainage and erosion problems, provide non-motorized improvements on Inglewood Hill Road, and to support stormwater needs of future development projects within the area.

A new sidewalk on the north side of Inglewood Hill Road will be supported by retaining walls and rockeries in some locations and will run from East Lake Sammamish Parkway to 212th Avenue NE.  Stormwater pipe will run on Inglewood Hill Road and outfall to Lake Sammamish.  NE 15th St, 208th Ave NE, 210th Ave NE, 211th Ave NE, and 211th Place NE will also have stormwater pipe installed in the road.  A new stormwater treatment vault will be placed at the intersection of Inglewood Hill Road and 208th Ave NE.

The City has partnered with Sammamish Plateau Water to install new watermain on Inglewood Hill Road from 211th Ave NE to 212th Ave NE. 211th Place NE to the north and south of Inglewood Hill Road and on 212th Ave NE south of Inglewood Hill Road will also be provided a new water main.  

The City was successful in receiving two grants from the King County Flood Control District:

  • King County Flood Reduction Grant in the amount of $250,000, and
  • King County Sub-regional Opportunity Fund in the amount of $851,078
