Dayton Street Utility Improvements

Project Limits


Upcoming construction activities, intersection closures
Over the past two weeks, crews have been working in the 3rd and 4th Avenue intersections. We appreciate your patience as crews continue to excavate the street to replace the aging and undersized utilities.

The 5th Avenue S and Dayton Street intersection will be closed to traffic from 7am - 5pm June 12, 13, 18, 19, 20, 21. During this work:

              •    Through traffic will be restricted.

              •    The intersection will be open on Friday, Saturday, and Sunday                                   during the Edmonds Arts Festival.

              •    Access to businesses, driveways, and parking lots will be                                           maintained.

              •    Sidewalks at the 5th and Dayton intersection will be closed;                                       pedestrian detours will be in place.

Community Transit buses will be running on alternate routes around work zones. Please visit Community Transit’s website for current rider alerts and routes:

The first phase of construction (Dayton Street from 3rd Ave S to 5th Ave S) will begin on May 13, 2019 and is anticipated to be completed in Fall 2019. Work during this phase will occur mostly between 3rd Ave S and 5th Ave S. Some sewer pipe rehabilitation work between 6th and 9th may be part of phase 1.

Traffic and pedestrian impacts

  • One lane of traffic, either eastbound or westbound, will be maintained on Dayton St during most of construction. Traffic control will be present to direct people through the work area during construction

  • Parking will be restricted in the work area

  • To provide safe working spaces for construction crews, there may be temporary intersection and/or block closures lasting for 1 to 3 days. We will notify businesses and neighbors ahead of these closures

  • Sidewalks and driveways will remain open except for short durations to maintain safety throughout the corridor

Phase 2 of construction (Dayton Street from 5th Ave S to 9th Ave S) will begin as early as Spring 2020 and last into Fall 2020.

The Dayton Street Utility Improvements Project will replace aging and undersized utilities along Dayton Street from 3rd Ave S to 9th Ave S. Improvements will include:
  • Adding stormwater pipe capacity to reduce flooding in downtown during heavy rainstorms

  • Replacing sewer and potable water pipes that are nearing the end of their lifespan

  • Upgrading curb ramps to be ADA-accessible at the intersections of Dayton Street and 6th, 7th, 8th, and 9th Avenues

  • Adding a sidewalk along the south side of Dayton Street from 7th to 8th Avenues

  • Design was completed at the end of 2018

  • Phase 1 (3rd Ave S to 5th Ave S) construction will begin in May 2019

  • Crews do not plan to work between October 2019 and March 2020 over the holiday season

  • Construction will be divided into two phases. The second phase of construction (5th Ave S to 9th Ave S) is expected to start as early as Spring 2020 and last into Fall 2020


Replace and upsize existing utilities on Dayton Street from 3rd to 9th Avenue. Improvements will include:

  • Replacing 3200 feet of stormwater pipe

  • Replacing 3800 feet of potable water pipe

  • Replacing 4300 feet of sanitary sewer pipe

  • New pavement on Dayton Street throughout the project limits

  • Constructing a new sidewalk on the south side of Dayton between 7th
    and 8th Avenues

  • Constructing ADA-accessible pedestrian curb ramps

  • Revise sidewalks and intersections at Dayton St and 6th, 7th, and 8th, and 9th Avenues


 ·  Construction costs estimated to be $7 million.
