14th Ave West - Road Extension

May 2019 Update

Snohomish County Public Works completed the Design Report Addendum for this project in January 2019. The Design Report Addendum identified a roundabout option as the north intersection improvement at Locust Way, and includes a roadway section, intersection configuration, and drainage alternatives for the project.

Public Works’ Environmental Services staff will work with consultants to conduct environmental studies in support of the future State Environmental Policy Act (SEPA) review. Study topics include: re-verifying the presence of streams, wetlands and their buffers; and cultural and historic resources. A noise analysis is currently underway. This work will take place within the public right of way and adjacent properties as allowed by adjacent landowners.  

A right of way specialist from Snohomish County will be reaching out to some property owners near the project area to receive rights of entry or temporary easements for the studies to be completed. Thank you in advance for your cooperation on these studies.


Snohomish County Public Works is proposing an extension of 14th Ave West to improve the north-south traffic circulation and expand mobility for bicyclists and pedestrians. The 14th Ave West extension project will include a two-lane road, bike lanes and sidewalks. A new intersection will be constructed near the 21400 block of Locust Way.

Public Meeting

Snohomish County Public Works held a public meeting on June 15, 2017 to discuss two projects in this area. The projects were the 14th Ave W road extension and the Logan Rd, Larch Way and Locust Way intersection improvements. Staff was available to answer questions, review proposed improvements, and gather feedback on potential designs.
