Environmental Review - Notice of Application
State Environmental Policy Act (SEPA)

The City of Shoreline expects to issue a SEPA Determination of Nonsignificance (DNS) on the non-project action for the 185th Corridor report which will serve as a guide for future development. See links below to SEPA Checklist and notice.

Council Selects Preferred Option

Over the past year, the City of Shoreline worked with the community to create a vision for the 185th Street Corridor which connects to the future light rail station on the east side of I-5. The corridor is created by three roads: N/NE 185th Street, 10th Avenue NE, and NE 180th Street.

The team looked at existing conditions, received initial community and stakeholder input (fall 2018), and then made several draft roadway options. The draft options were shared at meetings and through an online survey. A total of 375 people participated in the spring outreach meetings and online survey. Staff used their input along with technical analysis to develop hybrid mid-block cross sections that reflect the best mix of elements from the draft options.

On July 22, 2019, City Council selected a Preferred Option set of mid-block cross sections that shows travel lanes for cars and future frequent bus service, bicycle facilities, sidewalks, and amenity zones. Cross sections will be wider near and at intersections to allow for left, right, and U-turns.

The Preferred Option:

(To see illustrations of roadway cross-sections, please view the
July 22, 2019 Staff Report.)

N/NE 185th Street

  • 4-lane section (two travel lanes and two Business Access and Transit or “BAT” lanes for frequent bus service and vehicles making right turns).
  • Amenity zones, off-street bike lanes, and sidewalks, and a flex zone on the north side of the street for street furniture and plantings.
  • Fits in the 90-foot planned right-of-way (ROW) established during the 185th Street Station Subarea planning process.
  • Holds the north side curb to retain existing trees where feasible.

10th Avenue NE

  • 2-lane section (two travel lanes).
  • Buffered bike lanes, on-street parking (west side only), amenity zones, and sidewalks, and a flex zone on the west side of the street.
  • Fits in the existing 80-foot ROW.

NE 180th Street

  • 2-lane section (two travel lanes).
  • Enhanced bike lanes, amenity zones, and sidewalks.
  • Fits in the existing 60-foot ROW.

Next Steps

Over the summer, the study team will refine the corridor concept by developing intersection design options that will support the Preferred Option mid-block cross sections and develop a project delivery and funding strategy. The study team will return to Council in fall 2019 with the 185th MCS Report for Council discussion and adoption.

Open House 2: Materials and Presentation

The April 2, 2019 public meeting was attended by approximately 80 residents who were able to view and provide feedback on various options for the 185th Corridor street sections and opportunities for future community gathering places. If you were unable to attend, the following materials and presentation from that evening are available below.

The team developed a set of draft value-based criteria to evaluate each option against the project goals and objectives. Each study option was evaluated with a simple scale of low to high to see how well it benefits pedestrians, bicyclists, drivers, transit operators and riders, livability, and cost. A color-coded evaluation table is provided with each option that shows how it performs for different purposes. At this point in the process, no decisions have been made about which roadway cross section performs the best. Rather, the review and comparison of options will reveal opportunities, constraints, tradeoffs, and priorities.

Open House 1: Summary, Materials, and Presentation

In fall 2018, the City completed an initial outreach series to gather community and stakeholder input to help envision a corridor that will be safe for pedestrians and bicyclists; support bus and light rail transit service; address traffic flow; create gathering spaces; and encourage neighborhood businesses. A briefing of the events and input received can now be viewed in the Demographics Analysis & Outreach Summary.

The fall outreach events included walk and bike tours, community drop-ins, stakeholder meetings, and concluded with Open House 1 on Thursday, October 25, 2018.  Following are various materials and the presentation: 

For a different perspective, drone footage was taken of the 185th Corridor in part to understand how the corridor is currently used and to analyze some of its travel patterns. 

Changes to the 185th Street Corridor will happen incrementally over time. Currently, there is no designated funding for City capital improvements to the Corridor. However, the Corridor Strategy process will culminate in a plan that will guide how future public and private projects contribute to a cohesive corridor vision. Identifying possible small “quick win” projects and funding strategies will also be a part of this process.

Project Background

The City has been preparing for many years for the scheduled opening of the light rail Shoreline North/185th Station in 2024. Between 2013 and 2015, the City engaged the community in the development of the 185th Street Station Subarea Plan.  In March 2015, Shoreline’s City Council approved zoning updates for the 185th Street Station Subarea.


The 185th Street Multimodal Corridor Strategy (185th MCS) studies a corridor from Fremont Avenue N in the Hillwood/Richmond Highlands neighborhoods, east across Aurora Avenue N to 10th Avenue NE, south along 10th Avenue NE to NE 180th Street, and east on NE 180th Street to 15th Avenue NE in North City. The “Z” shaped corridor connects the Aurora Corridor, the future Shoreline North/185th Station, and the North City neighborhood.
