Colo. Rev. Stat. § 31-21-209
When any city or town consolidates with another city or town under the laws of the state of Colorado and has incurred a bonded indebtedness prior to such consolidation, such bonded indebtedness may be refunded by the consolidated city or town under the provisions of this part 2, as is provided for the refunding of other bonds in the same manner as it would have been the duty or within the power of the city council or board of trustees of the city or town which contracted such indebtedness to do had no such consolidation taken place. All the provisions of this part 2, including elections authorizing issuance of such refunding bonds, shall apply only within the former limits of the city or town which contracted such indebtedness. All refunding bonds so issued shall state in substance that they, together with interest thereon, are payable only by levies upon property situated within such limits as the same existed prior to such consolidation, unless the terms of consolidation shall provide that such refunding shall apply within the entire limits of the consolidated city or town.
