Our Mission

Seattle Streets Alliance organizes and mobilizes people to make every neighborhood a great place to walk, bike, roll, and live.

Our Vision

Seattle Streets Alliance envisions a Seattle where streets are safe, connected, and welcoming for everyone. Our neighborhoods are linked by people-centered streets that make walking, rolling, and biking comfortable, joyful, and part of everyday life — for children, seniors, and people of all abilities. These streets reflect neighborhood priorities, support community life, and help build a healthier, more climate-friendly city where everyone has real choices for how they get around.

Our Story

For 15 years, Seattle Streets Alliance has been at the heart of Seattle’s safe streets movement — neighbors organizing neighbors to make it safer and easier to walk, bike, roll, and gather on our streets.

Seattle Streets Alliance began as Seattle Neighborhood Greenways. We were founded in 2011 with the simple idea that people of all ages, abilities, and backgrounds should be able to walk, bike, and roll to where they need to go. We achieved early success bringing the concept of neighborhood greenways — traffic-calmed residential streets designed for walking and biking — to Seattle.

Our work quickly grew beyond greenways to envision a city where kids can safely walk and bike to schools and parks; elders and people with disabilities can get around to their daily needs; and communities of color who have been historically underserved are prioritized for community-driven safety investments — so that every neighborhood is a great place to walk, bike, roll, and live.

Seattle Streets Alliance works tirelessly with our coalition of neighborhood groups, volunteers, partners, and supporters to deliver real, on-the-ground change across the city. Our work has helped improve street safety, create more walkable communities, create a bikeable downtown, bring safe streets to walk and bike on to historically underserved communities, lay the groundwork to transform streets into community places for people, and much more.

Our Work

Street Safety: We advocate for safer speeds, better crossings, and proven safety designs so people walking, rolling, and biking can get where they’re going without fear.

Biking Connections: We work to ungap maps in Seattle’s bike and roll network so people of all ages and abilities can get to school, parks, and transit without riding in general-purpose lanes with car traffic.

Centering Equity in Advocacy: We partner with communities most impacted by traffic violence and disinvestment to push for safety and access where it’s needed most.

Walkable Neighborhoods: We work toward a Seattle where daily needs — groceries, schools, parks, and transit — are within a short walk, roll, bike ride, or transit trip.

Streets as Community Space: We support street and public space designs that create welcoming places to walk, gather, and thrive.

Our Approach

Seattle Streets Alliance’s work is rooted in grassroots organizing because we believe that local people have the knowledge and capability to change their communities for the better.

We deliver our mission in coalition with volunteer-led neighborhood groups that identify community needs, develop local solutions, and lead local campaigns to make Seattle’s streets safer for everyone. Together, these groups form a grassroots alliance that elects our board of directors and sets our annual citywide advocacy priorities.

Seattle Streets Alliance citywide staff provide policy and organizing expertise, strategic planning and citywide campaign coordination, coalition building with partners and allies, leadership development for neighborhood groups, and communications and media support.

Together, we build grassroots people power and movement power to shape city policy, priorities, and funding — and deliver on-the-ground change that make Seattle's streets safer and more welcoming for everyone.

Our work is powered by volunteers and donors like you.
