Background

The Denver Gazette reported that a citizen-led petition placed this charter amendment and a companion measure, Question 301, on the ballot in response to an annexation proposal that ultimately was not annexed into Castle Pines.

According to the city, the amendment would require Castle Pines voter approval for annexations of more than 20 acres under common ownership or a common development plan, with related or successive annexations added together toward that threshold.

The city's overview lists potential advantages, including direct voter approval and a consistent requirement written into the charter, and potential concerns, including an added step in the annexation process, removing the council's final say, and the possibility that property owners seek annexation elsewhere.

The Gazette reported that the city has since adopted its first annexation policy, and that opponents including the City Council argue the policy already provides a strong framework, while supporters argue voters should approve annexations.

Put on the ballot by Citizen petition (per Denver Gazette).
