Breaking: Castle Pines Petition For Annexation Approvals Makes November Ballot

Grassroots initiative began after attempted Crowsnest Annexation, would require citizen approval of annexations

According to preliminary numbers, a petition to require citizen approval of annexations into the City of Castle Pines has qualified for the November 2026 ballot. Two questions will be put before voters; the major question is whether to require annexations over 20 acres be approved not just by City Council but also by voters at the next regular election. This would give the electorate of Castle Pines an effective veto over major annexations, in addition to requirements under state law and city ordinance.

The initiative began after Ventana Capital attempted to annex Crowsnest into the City of Castle Pines in late 2025. People Against Annexing Crowsnest (PAAC) formed during that attempt and went on to lead the ballot initiative to require voter approval of annexations. To qualify for the ballot, organizers had to submit 1,344 valid signatures. PAAC organized petition circulators at grocery stores, community events, and neighborhood meetings.

Ventana later withdrew their annexation application with Castle Pines. The City of Castle Pines placed an emergency moratorium on annexations and is currently developing an annexation policy. Ventana is now seeking to develop the land as part of unincorporated Douglas County. The Douglas County Planning Commission punted on the proposal at their most recent meeting.
