Get Involved#
Seattle has a vibrant ecosystem of advocacy groups working to make our city more walkable, bikeable, and transit-friendly. Here are organizations you can join to make a difference.
Advocacy Organizations#
Seattle Streets Alliance#
Seattle Streets Alliance (formerly Seattle Neighborhood Greenways) organizes neighbors to build safer streets and stronger communities. Founded in 2011 as Seattle Neighborhood Greenways, they rebranded in March 2026 to better reflect their expanded mission.
Their work centers on four key areas: street safety through better crossings and traffic calming; filling gaps in Seattle’s bike network; centering equity by partnering with communities most impacted by traffic violence; and advocating for streets as community spaces that prioritize people over cars.

Transit Riders Union#
Transit Riders Union is a democratic organization of working and poor people — including students, seniors, and people with disabilities — fighting to preserve, expand, and improve the public transportation system in Seattle and beyond, so that every human being has access to safe, affordable, and reliable public transit.
They successfully advocated for ORCA Lift (the low-income fare program), conduct surveys and research on transit benefits, make electoral endorsements, and engage in direct outreach and organizing activities.

Seattle Subway#
Seattle Subway envisions “a city and region fully connected by fast, reliable high capacity transit.” They’re an all-volunteer, grassroots organization dedicated to promoting high quality transit for Seattle and the Puget Sound Region on the fastest possible timeline.
Their mission is to accelerate rapid transit investments by organizing grassroots support for fast, reliable mobility options that reduce car use — an integrated system, some underground, some elevated, but always out of traffic.
Get involved: seattlesubway.org — Volunteer, donate, or sign up for updates on regional transit campaigns.
Transportation Choices Coalition#
Transportation Choices Coalition brings people together to advocate for safe, sustainable, and equitable transportation across Washington. Their tagline “Transit for all” reflects a commitment to expanding access for every community in the state.
Their policy work spans transit funding, land use, and mobility — connecting transportation decisions to broader questions of equity and climate.

Commute Seattle#
Commute Seattle is Downtown Seattle’s Transportation Management Association, working to sustain a mobile, economically competitive Downtown through consulting services, discount transit passes, and regulatory support.
As an alliance of the Downtown Seattle Association, King County Metro, Sound Transit, and the City of Seattle, they provide commuters, employers, and property managers with resources for alternatives to driving alone.

Equity & Community Organizations#
Urban League of Metropolitan Seattle#
The Urban League of Metropolitan Seattle’s mission is to empower Black and other historically underserved people to thrive for generations through social and economic justice. Founded in 1930, they are the second-oldest civil rights organization in Washington State.
ULMS implements this mission through seven pillars: housing, education, workforce development, public health, entrepreneurship, civic engagement, and financial empowerment. Their work on housing and transportation equity connects directly to urbanism issues.

Seattle Transportation Equity Program#
The City of Seattle’s Transportation Equity Program works to ensure equitable access to transportation services and opportunities across Seattle’s diverse communities. Their Office of Equity & Economic Inclusion focuses on racial justice, inclusive contracting, and fair resource allocation.
Key initiatives include Title VI compliance, the Race and Social Justice Ordinance, and contracting equity efforts for disadvantaged businesses.
