Existing Conditions

Community Profile

A demographic analysis of people living within a half mile of the corridor and that shows that vulnerable and overburdened populations are more prevalent within the study area than in other areas across Snohomish County. Most vulnerable populations are likely to have safety concerns, technology barriers, and cost and time constraints.

This chart summarizes some of the key vulnerable populations living near the study corridor. The percentages of people categorized as low-income, people of color, or having limited English proficiency, are all considerably higher than the county-wide average. Of those with Limited English proficiency, Spanish was the most common language spoken at home, followed by Korean.

Roadway Conditions

There are many sections of SR 99 that are missing sidewalks on either one or both sides of the roadway. In these locations, people must use the shoulder to access bus stops, services, or their homes. When there is no sidewalk, travelers must walk, bike, or roll along the paved shoulder, placing them directly next to high-speed traffic without any separation or buffer. They must also frequently navigate around parked cars and delivery trucks that have stopped on the shoulder. The map below shows the location of sidewalks along the corridor.

Pedestrian crossings

There are six locations along this section of SR 99 where pedestrians can cross the street at a marked crosswalk. These marked crosswalks are located at the traffic lights along the corridor, which are on average spaced about 2/3rds of a mile apart from each other. This means that people wanting to cross the street may have to walk a significant distance out of their way to use a marked crosswalk. As a result, many choose to cross SR 99 where convenient. This can be challenging due to high corridor speeds, the number of travel lanes, and the lack of pedestrian refuge. The map in the transit section shows the locations of pedestrian crosswalks along the corridor in relation to transit stops.

Transit

Community Transit operates both the Swift Blue Line and the Route 101 along the SR 99 corridor.

The Swift Blue Line is a bus rapid transit line that runs primarily along SR 99 providing a connection between Everett Station and Aurora Village Transit Center. Buses run every 10 minutes on weekdays, and every 15-20 minutes on early mornings, evenings, and weekends.

Route 101 is a bus line that runs primarily on SR 99 and provides a connection between the Mariner Park and Ride and the Aurora Village Transit Center. Buses run about once every 30 minutes during the week and once an hour during the weekend.

Although the Swift Blue Line stops are located near protected pedestrian crossings at signalized intersections, many Route 101 stops are at mid-block locations and are a significant distance from the nearest crossing. This can be challenging for transit users who may need to cross SR 99 to access their bus stop, or to access their destination after completing a transit trip. The map below shows the locations of bus stops in relation to existing pedestrian crossings.

Speed

The posted speed throughout the study corridor is 45 MPH. High vehicle speeds can contribute to an uncomfortable walking and biking environment and increase the likelihood that a crash will result in a serious injury or fatality. This is especially true of vulnerable roadway users. Vehicle speeds are likely to be higher during off-peak, non-congested times like at night. As described in the Safety Report section, 73% of fatal and severe bicycle and pedestrian crashes occur at nighttime.
