Colo. Rev. Stat. § 37-48-141
If it appears to the satisfaction of the court, after having heard and determined all said exceptions, that the estimated cost of constructing the improvements contemplated in the official plan is less than the benefits appraised, the court shall approve and confirm said appraisers' report as so modified and amended, and such findings and appraisals shall be final and incontestable, except as provided in this article. In case the court finds that the benefits appraised are less than the estimated total cost of the execution of the official plan, exclusive of interest on deferred payments, it may at its discretion return said official plan to the directors of the district with an order directing them to prepare new or amended plans, or it may dissolve the subdistrict after having provided for the payment of all expenses theretofore incurred.
