Boulder County Ballot Issues

Note: This page lists only county ballot issues and measures. Individual towns and cities within Boulder County may be considering municipal ballot measures for the November 2025 election. Please check with your municipality to see if they intend to place any issues or measures applying to the incorporated areas within your town or city this fall.

Each year during the summer (typically in late July or early August), the Board of County Commissioners considers whether to advance any Boulder County-related issues to the November election ballot.
