Colo. Rev. Stat. § 31-25-1225
Any district organized pursuant to this part 12 may be dissolved after notice is given, publication is made, and a hearing is held in the manner prescribed by sections 31-25-1206 and 31-25-1207. The dissolution of the district may be initiated by filing in the office of the clerk of the governing body either a petition signed by the persons described in section 31-25-1205(2) or, in the case of a district which has not filed an operating plan and budget as required by section 31-25-1211 for two years, a resolution of the governing body. After hearing any protests against or objections to dissolution and if the governing body determines that it is for the best interests of all concerned to dissolve the district, it shall so provide by an effective ordinance, a certified copy of which shall be filed in the office of the county clerk and recorder in each of the counties in which the district or any part thereof is located. Upon such filing, the dissolution shall be complete. However, no district shall be dissolved until it has satisfied or paid in full all of its outstanding indebtedness, obligations, and liabilities or until funds are on deposit and available therefor. Notwithstanding any other provision of this section, upon petition of persons who own real or personal property in the service area of the proposed district having a valuation for assessment of not less than fifty percent, or such greater amount as the governing body may provide by ordinance, of the valuation for assessment of all real and personal property in the service area of the proposed district and who own at least fifty percent, or such greater amount as the governing body may provide by ordinance, of the acreage in the proposed district, the district shall be prohibited from incurring any new or increased financial obligations, shall impose its existing taxes, fees, and assessments solely to meet any existing financial obligations, and shall be dissolved as soon as the district has no outstanding financial obligations.
