• Surrey Downs Speed Limit Reduction

    In response to community concerns about high vehicle speeds and pedestrian safety, the Transportation Department will lower the speed limit of all streets in the Surrey Downs neighborhood from 25 mph to 20 mph in fall 2020. While school zones in Bellevue are signed for 20 mph during certain school hours, this project will be the first in the city to feature a 20 mph speed limit for all times of day. This project was selected from more than 100 candidate locations in the city following a prioritization process by the city’s Neighborhood Traffic Safety Services group.

    Project Update (November 2020)

    The work to install the 20 mph speed limit signs and new pavement marking legends occurred on Wednesday, Oct. 28, 2020. A follow-up traffic study will be scheduled for later in 2020.

    Why lower the speed limit

    Lowering vehicle speeds helps to make streets safer and more comfortable for people walking in the neighborhood, a key strategy envisioned in the community-supported East Main (Light Rail) Station Area Plan. Further, lower speeds supports the city’s Vision Zero effort to eliminate serious injuries and fatalities on city streets by 2030.

    The city plans to evaluate the effectiveness of the speed limit change through before-and-after traffic studies that measure vehicle speeds and through community feedback.

    What to expect

    A one-week traffic study—planned during September— will assess existing vehicle speeds at multiple locations throughout the neighborhood to compare against future conditions.

    To lower the speed limit, city staff will replace existing speed limit signs with 20 mph signs, add blue “Residential Area” signs at each neighborhood entrance, and repaint speed limit pavement markings. Additionally, a few new 20 mph pavement markings will be added in the neighborhood.

    Yard signs that indicate “20 is Plenty” are available to community members upon email request. These signs will be available to the community closer to the launch of the 20 mph speed limit (a notice will be posted at the top of this page). 


    This project is funded by the Neighborhood Traffic Safety Program (CIP PW-M-7). Project budget: $20,000.

    Frequently Asked Questions

    The Transportation Department has received numerous concerns from Surrey Downs residents about high vehicle speeds in the neighborhood. The concern was evaluated against approximately 100 other concerns from across the city through an evaluation framework. The framework takes into account vehicle speeds, traffic volumes, pedestrian facilities, pedestrian destinations and other factors along with field reviews. Though vehicle speeds are moderate, the neighborhood prioritized highly due to the lack of sidewalks and proximity to schools, parks and the future East Main Light Rail station. Due to speeds being moderately high, traditional traffic calming tools (e.g. speed humps) would be a costly addition and may not be effective at deterring but a few high-end speeders. Speed limit reductions have increasingly been found to decrease vehicle speeds. Additionally, the Surrey Downs community is relatively insulated from a high rate of outside of traffic. Therefore, community members can be reached directly through communication channels to inform them of the speed limit change allowing them to adjust their behavior.  
    The project will be evaluated to measure speeds before and after the speed limit is reduced. Staff will also collect community feedback following implementation to determine if modifications are needed. If the speeds do not decrease, there is project budget to support additional measures aimed at reducing speeds.
    No. The city does post 20 mph speed limits in school zones, but the school zone speed limit is only applied during certain times of day (e.g. during school bell times). Additionally, the city posts advisory speed limits (e.g. black lettering on yellow signs signifying a change in road conditions, such as a curve). As such, this will be the first regulatory 20 mph speed limit in Bellevue.
    At this point, no. Given that this will be the first 20 mph speed limit, the Transportation Department plans to learn how effective changing speed limit signs and neighborhood education can be in reducing vehicle speeds. Traffic studies collected before and after the speed limit reduction will help to determine effectiveness. The lessons learned from this project may be applied to future efforts to reduce speed limits, but that work is not currently programmed or funded.
    The Neighborhood Traffic Safety Program work to create a safer roadway environment for all users, enhance neighborhood livability and engage the community to become active participants in the traffic safety process. Recent projects include reducing cut-through traffic in Woodridge, improving safety and connectivity in Northwest Bellevue, improving traffic safety near Newport Heights Elementary and Tyee Middle School. Staff manage the 60+ radar signs in Bellevue along with the portable radar dolly, available for residents to borrow. If you have a traffic safety concern in your neighborhood, connect with us by completing a Request for Action.
