Thanks for bringing this concern to our attention. We are aware of this issue, and will add NW Sammamish Road to the list of requested radar speed signs.

Additionally, the City is preparing designs to improve this corridor, from the State Park Entrance to 193rd Place, including bike and pedestrian facilities. We will evaluate speeds along West Lake Sammamish during the design process to see if additional treatments are warranted.

Thanks,

Matt Ellis

Hello, we installed speed counters along West Lake Sammamish Parkway, to see if a traffic calming device could be used along this street. We use the industry standard of comparing the 85th percentile speed to the speed limit, which is 30mph. The 85th percentile speed was 39.6 mph, which is almost 10 mph faster than the posted speed limit. We will install a temporary speed sign along the roadway, and evaluate what treatments we can install for the long term. Additionally, we will pass on the concern to the police to increase patrols.

Thanks again for bringing this to our attention.
