Project Description

35th Avenue SE is completely within the urban zoned portion of the SW Urban Growth Area, the fastest growing UGA in Snohomish County - 46% by 2035. This project extends and completes urban level improvements between two State Routes by constructing a three lane roadway with a continuous middle turn lane, intersection improvements, and traffic signals where warranted. Significant residential and high density housing has occurred and/or is planned along the corridor where developed, frontage improvements have been intermittent and uncoordinated, leaving bicyclists and pedestrians, including the disabled, without continuous opportunities. The project will include Complete Streets containing dedicated bike lanes and continuous and fully ADA compliant sidewalks will enable pedestrians and cyclists to commute without competing with vehicle traffic. The project will ease congestion during commute hours when the volume/capacity is typically exceeded. Construction includes a new drainage system with storm water detention and treatment facilities in compliance with current state and local standards. Improvements also include clear zone obstacle removal/relocation where feasible and full width overlay upon completion.
