Annexation is the legal process by which a city adds to its jurisdiction. The City of Dacono’s authority to annex territory is established by Section 30, Article 11 of the Colorado Constitution and the Colorado Revised Statutes, (CRS 331-12-10). The basic requirement for property to be annexed voluntarily is that at least one-sixth of the perimeter of the area proposed for annexation is contiguous with the city. The state statute allows that this one-sixth contiguity may be established by the annexation of one or more parcels in a series. Annexations may be considered together and completed simultaneously.
