Colo. Rev. Stat. § 38-6-107
It is the duty of the commissioners to estimate, fix, and determine the fair and actual cash market value of all property proposed to be taken for the improvement, without reference to the projected improvement, and the fair, direct, and actual damage caused on account of said improvement to other property not taken for the improvement. The commissioners shall provide for the payment of the total amount of their awards for land taken and damaged, in all cases where the resolution or ordinance authorizing the improvement so provides, by assessing against the owners of all real estate which, in their opinion, will be specially benefited by the proposed improvement the amounts of said benefit as special assessments, and such commissioners shall assess the balance required to make said total amount as a general assessment against the petitioning city or city and county. Such special benefits shall be assessed against the owners of each lot or parcel of property that is, in the opinion of said commissioners, specially benefited by said improvement, which said special benefits shall be a lien on the property so charged, and shall be collected as provided by the charter or ordinance of said city or city and county, and when so collected shall be paid into the treasury of said city or city and county as a separate fund, to be used for the payment of the awards and damages.
