MASS Coalition Urges Co-Founder Mayor Wilson to Advance High‑Impact Transportation, Accessibility, Livability, and Climate Priorities
Read the MASS Coalition’s full letter to Mayor Wilson
Seattle, WA — The MASS (Move All Seattle Sustainably) Coalition—an alliance of 13 organizations working toward a safer, more accessible, and climate‑aligned transportation system—released a public letter today calling on Mayor Katie Wilson to take swift, visible action on a set of near‑term priorities. With Wilson’s election—and her deep roots in the movement, the MASS Coalition is stepping forward with renewed clarity, unity, and ambition. As its letter notes, Mayor Wilson’s “recent electoral victory creates a historic mandate and an opportunity to translate progressive campaign commitments into real results for Seattle,” citing her long record as a transit advocate and her previous leadership of the coalition. Wilson co-founded the MASS Coalition in 2018 to connect Seattle’s diverse and vibrant neighborhoods, minimize reliance on private vehicles, achieve Vision Zero, make Seattle carbon-neutral, create walkable communities, and ensure equitable access to transportation for all people.
A Vision for a City That Moves People, Not Just Cars
The coalition’s collective recommendations span four areas—mobility, accessibility, livability, and climate—and emphasize projects that are urgent, equitable, and feasible. These actions, MASS writes, “will improve Seattle in multiple, mutually reinforcing ways” and represent significant early opportunities for the Wilson administration. Its letter calls for redesigning Seattle’s most dangerous streets, expanding frequent transit, and filling critical gaps in the bike network: not as isolated projects, but as the backbone of a transportation system that allows people to move safely and reliably without needing a car. The letter also urges the City to strengthen neighborhood livability and ensure communities can meet daily needs close to home through people‑centered planning and more connected urban design. It also calls for stronger climate accountability by requiring transportation and related projects to demonstrate how they support Seattle’s long‑term emissions and mode‑shift goals.
The MASS Coalition Stands Ready to Partner
The MASS Coalition brings together a broad cross‑section of Seattle’s transportation, climate, and community organizers and advocates. It currently consists of 350 Seattle, America Walks, Cascade Bicycle Club, Fix the L8, Nondriver Alliance, Seattle Streets Alliance, Seattle Subway, Seattle Transit Blog, Sierra Club Washington, Transit Equity for All, Transit Riders Union, Transportation Choices Coalition, and the Urbanist. As stated in its letter, the coalition is ready to collaborate with the new administration: offering volunteer power, technical expertise, and community engagement capacity to help accelerate implementation. “We stand ready to collaborate with your administration to pursue these actions…Seattle can achieve something truly great,” the letter concludes, “when city government works alongside the community.”
