Colo. Rev. Stat. § 37-4-107
Any property owner may accept the appraisals in his favor of benefits and of damages and of lands to be taken, as made by the appraisers, or may acquiesce in their failure to appraise damages in his favor, and shall be construed to have done so unless, within ten days after the last publication provided for in section 37-4-106, he has filed exceptions to said report or to any appraisal of either benefits or of damages, or of the value of land to be taken. All exceptions shall be heard by the court beginning not less than twenty nor more than thirty days after the last publication provided for in section 37-4-106 and determined in advance of other business so as to carry out, liberally, the purposes and needs of the district. The court may, if it deems necessary, return the report to the board of appraisers for their further consideration and amendment and may enter its order to that effect. If, however, the appraisal roll as a whole is referred back to the appraisers, the court shall not resume the hearing thereon without new notice, as for an original hearing thereon. But the court may, without new notice, order the appraisers to revise and amend the roll when the order of the court specifies the changes to be made.
