SDOT’s Sidewalk Accessibility Program includes planning, prioritization, design and construction of infrastructure to enable residents with disabilities full access to Seattle pedestrian facilities. These improvements include curb ramps, accessible pedestrian signals (APS) and new technology evaluations.

Curb Ramps

The goal of the curb ramp program is to improve access to Seattle’s network of sidewalks and walkways, particularly those for whom mobility is limited.

Curb ramp design and construction includes a ramp with a tactile warning surface, landings, and necessary sidewalk transitions and (minor) utility modifications.

Seattle builds new curb ramps when we install new marked crosswalks, by citizen request, and using Pedestrian Master Plan-developed criteria that identifies high-demand areas.

Customer Requests

The Seattle Department of Transportation (SDOT) will install curb ramps as soon as funding allows when requested by qualified individuals with disabilities at locations not otherwise scheduled for improvement. The program is not intended to address community concerns other than access for people with disabilities.  Based on current funding it may take up to three years from the approval date for curb ramps to be installed. To request a curb ramp, contact Brian Dougherty at 206-684-5124 or complete this online form.

Prioritization List

Each year SDOT updates our curb ramp inventory list. The prioritization effort weighs various factors to determine the ranking of our inventory of curb ramps, including demographics, proximity of transit connections, and proximity of pedestrian generators (hospitals, schools and parks).

The number of curb ramps constructed from this list each year will depend on annual funding. For the next two years, the backlog of citizen requests will be addressed before building ramps off the prioritization list, although some requested ramps are also on this list.

Accessible Pedestrian Signal (APS)

An Accessible Pedestrian Signal is pedestrian push button that produces an audible signal and vibration to indicate when it is safe to cross the street. Such devices can be helpful to people who are visually or hearing impaired.

Starting in 2009, a portion of the Sidewalk Accessibility Program funding is set aside for APS improvements.

New Technology Evaluations

Disability advocacy groups occasionally request that SDOT test new, alternative technologies focused on improving accessibility and mobility of people with disabilities within our transportation system. SDOT will devote a portion of our ADA funding to testing and evaluating these new technologies.

  • Let us know if you have would like SDOT to explore new technologies that would make our pedestrian facilities more accessible. Contact Brian Dougherty at 206-684-5124 or complete this online form.
