Members include the mayors, managers and council members of these resort towns.  CAST has more than a dozen Associate Members that include Colorado counties as well as out-of-state towns and counties.

The Association was formed in part to recognize that resort communities face unique challenges in providing municipal services to residents and visitors.

Member municipalities share the benefits of our diverse knowledge, experience and leadership through meetings, conferences, surveys and other informational venues, as decided by the members.

CAST members use the power of the coalition to seek support for legislation that will benefit and sustain the mountain communities. We support actions that keep our communities livable, protect our pristine environment, and promote affordable housing, multi modal transportation, climate action and sustainable tourism. Our goal is to ensure an exceptional quality of life for citizens and a positive experience for visitors.
