Seattle: Sidewalk Network Analysis

Seattle used a GIS-based approach to prioritize potential sidewalk projects. The city first analyzed sidewalk needs based on the presence and characteristics of existing sidewalks, such as physical buffers, traffic speeds and volumes, and block length. The city then analyzed sidewalks based on three demand analyses—potential pedestrian demand, socioeconomic / health equity, and corridor function—and weighted them by category to determine areas of most need.

Seattle created an alternate Neighborhood Projects Fund to construct projects proposed by residents.6 Seattle’s sidewalk improvements are funded by the city’s nine-year $365 million Bridging the Gap levy, supplemented by state or federal grants.
