The NE 178th Street Improvements Phase 2 Project will provide transportation and pedestrian improvements on NE 178th St. between Brookside Blvd. NE and 33rd Ave NE, and 35th Avenue NE between NE 178th Street and the driveway to Brookside Elementary School and includes the following features:

  • On NE 178th Street, curb & gutter and concrete sidewalk on both sides of the roadway and a bicycle lane on the north (uphill) side
  • On 35th Avenue NE, curb & gutter and sidewalk on the east side of the roadway, along with a regraded roadway at the NE 178th intersection
  • Intersection geometry modifications at the NE 178th/Brookside Blvd. intersection
  • Replacement of the McAleer Creek culvert under NE 178th east of 37th Avenue NE
  • Pedestrian activated crosswalk signals on NE 178th at the Brookside Blvd. and 33rd Avenue NE intersections
  • Illumination improvements

The project addresses safety shortcomings in this popular urban corridor adjacent to Brookside Elementary School, Eagle Scout and Animal Acres Parks.

The contractor for the project is KLB Construction of Mukilteo, Washington. 



Construction Schedule

The contractor intends to begin mobilizing equipment on site the week beginning July 2, and the first working day is scheduled for July 6.  The first work area will be between 33
rd and 37th Aves. NE, and work will occur six days per week, ten hours per day (Monday-Saturday) during July and August.  Upon completion of the major items of work between 33rd-37th, the work area beginning in September will move to the 37th-Brookside section of roadway which will include replacement of the McAleer Creek culvert.  Work crews are expected to return to a regular forty hour work week beginning in September.

Completion of the project is scheduled for December 18, 2015.

Road Closures

The work will be conducted in phases and NE 178th
 Street will be closed to through traffic for the duration of each phase.  Access will still be provided for local traffic and pedestrians, along with emergency services, mail delivery, garbage service, and other deliveries.  Traffic on NE 178th Street will be diverted onto a detour route using NE 180th Street and 33rd Avenue NE.

Driveway access to residents within the project area may be unavailable for short periods of time while the contractor builds new driveway approaches.  This will be coordinated with individual residents.

Background & Benefits

The project will replace and upgrade a failing 75” x 90” oval CMP with a new fish passable culvert to better fit the area of the creek. Work will include excavation of the road prism, and widening of the channel bankfull width within the public right of way. Graded channel bed sediment suitable for fish will be placed in the culvert, which will be countersunk to a depth greater than 20% of the culvert rise. Disturbed areas above the OHW elevation will be planted with native vegetation. All work will occur within the City’s right-of-way.

Street and Storm Improvements: pavement reconstruction on NE 178th Street (33rd Avenue NE to NE 180th Street) and 35th Avenue NE (South side of Brookside Elementary School to NE 178th Street). Street improvements include new base course, HMA paving, storm drainage improvements, pedestrian crossing with rapid flashing beacons, retaining walls, driveway grading, curb and gutter, and sidewalks. An existing CMP culvert will also be replaced on NE 178th Street with a new fish passable culvert.

Water System Improvements: Minor improvements are planned to the water system including relocation of existing water services, where they cross underneath new retaining walls, relocation of meter boxes, adjusting valve boxes, and relocation/adjustment of fire hydrants to grade.
