Colo. Rev. Stat. § 31-25-819
No board member nor any employee of the board shall vote or otherwise participate in any matter in which he has a specific financial interest, defined as a matter in which the member or employee would receive a benefit or incur a cost substantially greater than other property owners within the district. When such interest appears, it is the duty of the board member or employee to make such interest known, and he shall thenceforth refrain from voting on or otherwise participating in the particular transaction involving such interest. Willful violation of the provisions of this section constitutes malfeasance on the part of a member of the board and is grounds for instant dismissal of any employee. The governing body may by ordinance provide for automatic forfeiture of office by a board member for violation of this section.
