Vision Zero Community Partnership Meetings

In 2021, Boulder County led two Vision Zero Community Partnership Meetings (previously hosted by the City of Boulder). These meetings provide an engagement opportunity for all local, regional, and state-wide agency partners, Transportation Advisory Boards, bicycle advocacy groups, local school districts, and law enforcement officials to collaborate on our Vision Zero safety goals, policies, and projects. The mission of the Vision Zero Community Partnership Meetings is to share knowledge and insight on safety goals, educational resources and campaigns, projects, etc., continue the momentum that started with the City of Boulder bringing multiple agencies, groups, and other community members together, and help push all our collective safety goals forward.
