Winter 2017

The City of Edmonds’ Public Works and Parks Departments are currently working on capital improvement projects at various locations around the City. Below you will find a brief description of the projects anticipated to begin construction in 2017.

2017 Sewerline Replacement Project
The project will replace approximately 2,500 feet of 10-inch diameter sewer main with 18-inch diameter sewer main. This pipe replacement will address needed repairs due to pipe age, damage, root intrusion, and provide more capacity.

The project will begin at the intersection of 10th and Maple and will continue west on Maple and into Shell Valley. The replacement will continue through all of Yost Park and continue onto Shell Valley road and terminate at the intersection of Shell Valley Road and Pioneer Way. Construction is scheduled to start late spring 2017 and be complete by early fall 2017.

2017 Cured-In-Place Pipe (CIPP) Sewer Rehabilitation
Scheduled for design and possible construction in 2017, this Project will seek to rehabilitate approximately 4,500 feet of existing sewer main in several locations throughout the City. Cured-In-Place-Pipe is a method of rehabilitating existing pipe and adding decades to their operational lifetimes. CIPP is a trenchless technology, meaning that long trenches do not have to be dug, and as such is an excellent pipe repair method for hard-to-excavate areas, areas with significant traffic, or those portions of the City’s sewer network that run through private property.

Highway 99 Sewer Pipe Rehabilitation
This project will replace approximately 500 feet of existing failing sewer pipe on Highway 99 under the sidewalk between Starbucks and Dick’s Drive-in. Construction is scheduled to begin in spring 2017.

Seaview Park Infiltration Facility
The project will construct an infiltration facility beneath the parking lot at Seaview Park, to intercept stormwater from the surrounding neighborhoods. The system will include water quality treatment and a series of underground injection wells that will allow storm water to infiltrate into porous soils. A small biofiltration unit will replace an existing catch basin to provide treatment for parking lot storm runoff.

This project seeks to divert some of the peak stormwater flows that currently enter Perrinville Creek during significant rain events. By keeping it out of the creek erosion of the creek bed will be reduced. Water quality and habitat for fish will be improved as well. Construction is anticipated to begin in late summer 2017.

Northstream Culvert Rehabilitation and Pipe Abandonment
A culvert conveying Northstream Creek under 196th Street SW at approximately Olympic Avenue will be rehabilitated using CIPP (Cured In Place Pipe) trenchless technology. In addition, a 30” diameter pipeline paralleling the roadway on the south side of 196th St. will be abandoned. This project will increase capacity and reduce the potential of a washout event in this system. Construction is scheduled to begin in summer 2017.

76th Avenue W @ 212th Street SW Intersection Improvements project
The project will install a new traffic signal at 76th Ave. W @ 212th St. SW with the addition of left turn lanes, right turn lanes, and bike lanes. Also, new sidewalk, curb and gutter, utility upgrades (including stormwater, water, and sewer), and new street lights will be added. The overhead utilities within the intersection will be converted to an underground system. 76th Ave. W from 220th Street SW to Olympic View Dr. and 212th Street SW from 84th Ave. W to 72nd Ave W will be re-striped to one through lane in each direction, a two-way left turn lane, and bike lanes on both sides of the street.  

The project will reduce delay at 76th Ave. W @ 212th St. SW by converting the signal operation from split phasing for the northbound and southbound turning movements to concurrent movements. The addition of bike lanes will improve bicycle safety and the bicycle network connections to adjacent jurisdictions (Lynnwood and Mountlake Terrace are also involved in this project). All modes of travel will then be able to move through this congested intersection more efficiently and with increased safety margins.

Construction is scheduled to start in spring 2017 and be completed by December 2017.

15th St. SW Walkway
The project will construct the missing link of sidewalk on 15th St. between SR-104 and 9th Ave.S. Construction started in January and will provide approximately 200 feet of new sidewalk on the south side of 15th St. SW from 8th Ave. S to 9th Ave. S. This will allow pedestrians to walk safely and comfortably between Edmonds Way and 9th Ave S.

236th St SW Walkway (Edmonds Way to Madrona School)
This project will construct approximately 600 feet of curb, gutter and sidewalk on the south side of 236th St SW from Edmonds Way to the Madrona School. Part of the project involves widening and reconstructing 236th St SW from Edmonds way to the school entrance. This project was funded using a Safe Routes to School grant and will improve pedestrian safety.

The 236th St SW Walkway went to construction in October 2016 and was suspended for the winter in November. Construction will resume in spring 2017 and be completed within 4 to 6 weeks.

238th St SW Walkway (Edmonds Way to Hwy 99)
This project, funded through a Transportation Improvement Board (TIB) grant, will install sidewalk on the north side of 238th St SW between Edmonds Way and Highway 99. This project will provide a continuous sidewalk for pedestrians to access existing bus stops, a Community Transit Park & Ride and the Safeway Shopping Center. Construction is expected to begin in spring 2017 and be completed by summer.

2017 Pavement Preservation Program
This is part of the City’s program to preserve and maintain the City’s street system by installing new pavement or sealing pavement to extend its life. The City partners with Snohomish County to complete the overlay work and this year’s program will pave approximately seven lane-miles of City streets.  

Traffic Signal Improvements    
The project consists of left turn signal modifications at the following signalized intersections: (1) SR-104 @ 100th Ave. W: existing protected left turn phasing for the northbound and southbound movements (left turn allowed during Green Arrow only) will be converted to protected / permissive left turn phasing (left turn allowed during Green Arrow and Flashing Yellow Arrow, i.e. yield to opposing traffic); (2) 76th Ave. W @ 220th St. SW: existing protected left turn phasing for the northbound and southbound movements (left turn allowed during Green Arrow only) will be converted to protected / permissive left turn phasing (left turn allowed during Green Arrow and Flashing Yellow Arrow, i.e. yield to opposing traffic); and (3) SR-104 @ 95th Pl. W: existing permissive left turn for the eastbound and westbound movement (left turn allowed during Green Ball) will be converted to protected left turn phasing (left turn allowed during Green Arrow only).

The purpose of the conversion at the SR-104 @ 100th and 76th Ave. W @ 220th St. SW intersection is to reduce intersection delay, while the one at SR-104 @ 95th Ave W is to improve the safety of the left turn movements due to existing limited sight distance of the opposing through movement / roadway curvature.

Construction started in January 2017 and is scheduled to be completed by December 2017.

Wayside Horn Project
The project will install Wayside Horns at the Main St. and Dayton St. railroad crossings owned by Burlington Northern Santa Fe (BNSF).  The purpose of the project is to reduce noise pollution from train horns throughout Edmonds. Construction is scheduled for 2017 (schedule is dependent on the City receiving the necessary approvals from BNSF).

Audible Pedestrian Signals (APS)
The project will add Audible Pedestrian Signals at several signalized intersections within the City. The APS system will communicate the WALK and DON’T WALK intervals through audible tones and vibrotactile surfaces to pedestrians who are blind or have limited vision. Construction is scheduled to be completed by fall 2017.

Traffic Calming Program
The project will add traffic calming devices on City streets that qualify for the program. To find out more information about this program, please visit the City’s website at

ADA Curb Ramps
The project will install new ADA compliant curb ramps. The project will improve accessibility to existing sidewalks for pedestrians with disabilities. The ramps are scheduled to be completed by fall 2017.

2017 Waterline Replacement Project
This project is part of the City’s ongoing program to replace and upgrade existing waterlines that are reaching the end of their useful service life or has some other existing system deficiency. A robust utility rehabilitation program is critical to maintaining potable water quality, as well as reducing service disruptions due to leaks and breaks.

The 2017 Waterline Replacement Project will replace approximately 7,200 feet of water main and water services in three areas of town: Elm Street from 6th to 8th Avenues South, 6th Avenue North from Daley northward through Aloha Way, and 186th St SW from 78th Place to 82nd Avenue West, including side streets.

Frances Anderson Bandshell Replacement
The project consists of demolition of the existing bandshell and stage, construction of a new concrete stage with concrete stairs and ramps on each side. A new curvilinear shelter roof will be mounted on concrete plinths located at the four corners of the stage. A new eight foot tall stage backdrop will be constructed of wood cardecking. The project is currently under construction and should be completed by March.

Veterans Plaza
The Edmonds Veterans Plaza is a community project to support, create and build memorials to Edmond’s military veterans. The project will provide site improvements and enhancements to the existing City of Edmonds Municipal Court Plaza and immediate surroundings. It includes a new stone-clad wall with two waterfall feature elements, related mechanical, plumbing and electrical work, new paving, walls, stairs and handrails, new site furnishings and lighting, modifications to existing planting and irrigation, minor modifications to the existing parking lot and new utility connections. Construction began in February and will continue through mid-May.
