Approved 2025 Boulder County Ballot Measures

Following public hearings in August, the Boulder County Commissioners voted to place two county ballot measures—the Open Space Sales and Use Tax Extension and the Mental and Behavioral Health Sales and Use Tax—on the November 2025 General Election ballot. During the public hearing and deliberation process, the commissioners approved amendments to the proposed ballot language for each measure. The final language is included in the resolutions listed below.

For the resident-proposed Niwot Public Improvement District, petitioners requested a later hearing date, which means the measure will not meet the deadline for inclusion on the November 2025 ballot.

  A Resolution of the Board of County Commissioners of Boulder County approving a ballot title for the November 4, 2025, general election to extend for ten years the existing 0.15% countywide open space sales and use tax for the purpose of acquiring, improving, managing, and maintaining open space lands and other open space property interests.

Community Member-Proposed Ballot Issue: Niwot Area Public Improvement District of Boulder County

August 19, 2025 Update: The petitioners for the Niwot PID requested a later hearing date to make changes to the original proposed ballot language, which means the measure will not meet the deadline for inclusion on the November 2025 ballot.
