In plain language
A VoterDecoder summary of the official measure text.
Castle Pines Ballot Question 300 would add an annexation rule to the city’s home rule charter. Land over 20 acres owned or controlled by one owner or group, or part of a common development plan, could be annexed into the city only with approval from city voters. Several related annexations would be counted together as one. A YES vote adds this voter-approval requirement. A NO vote leaves the charter unchanged.
