Colorado Revised Statutes Title 32. Special Districts § 32-7-104. Territorial requirements for service authorities

(2)(a) Except as provided in paragraph (b) of this subsection (2), a service authority shall include all of the territory of at least one county and may include such additional entire counties as may be proposed, if each county has some contiguity with another county within the service authority and does not result in the formation of an enclave.

(b) In no event shall any service authority be formed in the metropolitan area of Denver which does not include that part of Adams county excluding census enumeration districts 1, 2, and 3 of the east Adams division, and that part of Arapahoe county excluding census enumeration districts 1, 2, and 3 of the east Arapahoe division, as such districts and divisions are used by the United States bureau of the census in designation of land areas for the purposes of the 1970 census, and all of the city and county of Denver, and all of Jefferson county, but an additional county or additional counties may be included.

(3)(a) Except as provided in subsection (2)(b) of this section, no county may be divided upon formation of a service authority or thereafter except in the case of a municipality having territory in two counties which are not within the same service authority, either proposed or formed, in which event the municipality may be included in either of two service authorities without regard to county boundary lines, as provided in paragraph (b) of this subsection (3).

(b) Neither the governing body nor the residents of any such municipality shall participate in any of the procedures by which the service authority is originally formed, but, after a service authority is formed which includes the territory of either county, such municipality may be included in the service authority to which it directs its request for inclusion in the manner provided in section 32-7-131.
