Voters in Castle Rock will be asked whether to allow people to openly carry firearms on town property and whether to include that right in the town charter.
The Denver Post reports the Town Council voted 6-1 on Tuesday to put the questions to the voters on Aug. 19.
The council voted in January to repeal a ban on openly carrying firearms in town-owned public buildings and parks, but opponents gathered enough petition signatures to block the measure.
Council member Chip Wilson voted against the language of the ballot measure Tuesday, saying it was confusing and the process has been rushed.
Council member George Teal, who voted in favor of the measure, says it reaffirms constitutional rights.
Castle Rock, population 51,000, is in Douglas County just south of Denver.
