Description of Improvements

The City of Kirkland is using Sound Transit funds to build a shared-use pedestrian and bicycle path along Northeast 85th Street that will connect Kirkland's downtown to the new Bus Rapid Transit interchange on I-405

Kirkland will build the path along the south side of Northeast 85th Street, between Sixth Street and 114th Avenue Northeast by building walls to increase the width of Northeast 85th Street.  A "pedestrian bridge" will be constructed over the short section of the Cross Kirkland Corridor trail that crosses underneath Northeast 85th Street. During construction of the pedestrian bridge section, there will be a detour for users of the Cross Kirkland Corridor. Since the project adds additional impervious surface for the shared-use path, it builds a new stormwater detention vault near 6th Street.  Additionally, the project adds pedestrian lighting throughout the project for the safety and visibility of the shared-use path users.

Traffic and Pedestrian Route Impacts

It is anticipated that Northeast 85th Street will be reduced to a single lane eastbound from Peter Kirk Park to 114th Avenue Northeast, and a single lane westbound to downtown Kirkland from 114th Avenue Northeast to Sixth Street. During construction of the pedestrian bridge section, there will be a detour for users of the Cross Kirkland Corridor (CKC).

 

F.A.Q.'s

Will there be a connection to the CKC trail?

Not with this project due to the elevation of the roadway compared to the CKC. Northeast 87th Street & 114th Avenue Northeast will provide the most direct connection for CKC users to transition to the NE 85th Street shared-use pathway.

 

 

Why is the CKC trail closure so long?

The contractor has scheduled 9 months to complete the new bridge and the trail is closed during the construction for the safety of trail users. Temporary detours are in-place to guide trail users around the construction site while the bridge is under construction. The CKC trail is anticipated to reopen in spring 2026.

There are three running races that utilize the CKC trail that have their distances/routes certified occurring this fall.  Our contractor is required to open the trail and repair the trail surface to allow safe use for these events in October (Lake Washington Half, October 18), November (Turkey Trot, November 16), and December (12k’s of Kirkland, December 14).  The contractor will open the trail from Friday to Monday when these events occur.  

 

 

Why is the road narrowed to 2 lanes?

The two eastbound lanes are now part of the construction project work zone as shown in the detail below. One lane will be used as a travel lane for trucks and equipment and the other lane will be partially demolished during excavation for the structural wall.

Why do we need this project?

This is a critical multimodal connection between Downtown Kirkland and regional bus rapid transit (STRIDE). Funding for this connection was voter-approved in 2016 as part of the ST3 System Plan. Moreover, this connection supports Council’s vision for a safe, connected multimodal transportation network as established in the Transportation Strategic Plan, and supports future development of the NE 85th St Station Area as a thriving, walkable district linked by transit.   

 

It’s so steep, what are the grades and is it ADA compliant?

Typically, if feasible, a pedestrian access route running slope should be designed less than 5% grade. The grade of the shared-use path is approximately 6%.  However, the path is ADA compliant because of the exception in PROWAG (Public Right-of-Way Accessibility Guidelines)[RW1]  allows the path to match the grade of the adjacent street, even if the grade exceeds 5%.

Preamble D. Chapter 3: Technical Requirements; Grade

Where pedestrian access routes are contained within a street or highway right-of-way, the grade of the pedestrian access route shall not exceed 1:20 (5.0%). An exception permits the grade of the pedestrian access route to not exceed the grade established for the adjacent street or highway, where the grade established for that adjacent street or highway exceeds 1:20 (5.0%) (R302.4.1).


 [RW1]PROWAG (Public Right-of-Way Accessibility Guidelines) and the ADA (Americans with Disabilities Act) Standards are related but distinct guidelines for accessibility, particularly in public spaces. PROWAG focuses on accessibility in public rights-of-way like sidewalks, streets, and crosswalks, while the 2010 ADA Standards cover a broader range of facilities and environments, including buildings and transportation. PROWAG provides more detailed technical specifications for elements like curb ramps and pedestrian signals, often clarifying or expanding upon the general accessibility requirements outlined in the ADA Standards.  

 

 

Why isn’t there seating?

Along with not being part of the original scope, seating areas typically require level landings and adjustments to the grading of the path to provide flatter grades (and steeper grades to make up for these flat areas), would make the path non-ADA compliant.

 

What traffic analysis was conducted during design and what are the project mitigations?

While a detailed traffic study was not a requirement for the project, the CIP and Transportation groups worked through several alternatives before selecting this configuration. This review was based on evaluation criteria such as qualitative impacts to the traveling public, safety of the roadway within the project limits, construction costs, and schedule. In addition, traffic analysis was performed in coordination with our project and WSDOT's I-405/NE 85th Street interchange project. A traffic analysis of the lane reductions was completed by City Transportation, and WSDOT's consultant verified the City's work and conclusions. This analysis looked at potential queuing/delay on NE 85th Street from the City’s project impacting the I-405 off-ramps during their project construction to determine the potential impacts to safety and operations. After all the analysis and coordination with WSDOT was completed, the least impactful design was selected which is currently being utilized.

Staff will monitor the traffic and make adjustments as necessary.

 

Has there been outreach to downtown businesses?

Beginning in 2024, the project team conducted outreach meetings with property owners and management for those directly impacted by the project.  This year, we've increased our efforts and met with numerous community and business groups regarding the project. The reduction of NE 85th St to two lanes was highlighted in each presentation. The Project Update mailer went to all businesses and residents from Forbes Creek to Houghton on the west side of 405, and nearly 10,000 addresses. Notice has gone out in utility billing mailings, and mentioned at multiple WSDOT quarterly project update meeting. While never perfect, our outreach strategy has been working to notify the community at large as well as businesses specifically. Included in all community conversations is mentioning that Central Way will also be paved this summer, mid-August to September.

General Information: Tree removal and Mitigation

There will be significant tree removal to build the project. Regarding the tree replacements, Kirkland is following our tree code.  We will plant street trees along Northeast 85th Street and add evergreen trees to the Cross Kirkland Corridor, but there is not space to replant all required tree replacements within the project site.  The project will pay into the City's fee-in-lieu program which plants trees throughout Kirkland to maintain our tree canopy to fulfill the required mitigation ratio.

How many trees are being removed and replanted?

241 impacted trees are marked for removal. 122 trees have been identified for required mitigation and the remainder are mainly small diameter and non-viable trees which are not regulated by Kirkland’s tree code (KCZ Chapter 95).

61 trees will be replanted on site, some as street trees adjacent to the shared-use path and douglas fir trees will be planted by the CKC. The trees selected for planting on site are of generally higher quality than the ones being removed. In addition to Douglas Fir, the other replanted tree species include Greenspire Little Leaf Linden, Karpick Maple, Frontier Elm, Green Mountain Sugar Maple, Black Tupelo, and Eddies White Wonder Dogwood. 65 trees which are unable to be replanted on site will be mitigated through the fee-in-lieu program as required by Kirkland’s tree code. 

 

How does fee-in-lieu work? (tree related)

After completion of the project, the engineer will track and report to the Planning Department, the actual number of required mitigation trees which were unable to be replanted on site. The number of trees reported will be used to calculate the fee-in-lieu final amount which the project will be required to pay. At the time of this project update, the code reflects a unit cost of $450.00 per mitigation tree. The funds collected from fee-in-lieu mitigation helps fund and support the City’s Forestry Account. The Parks Department utilizes the Forestry Account for tree canopy restoration planting projects in various natural areas throughout the City.
