On approval of a plan submitted in accordance with § 26–404 of this title, the county commissioners or county council shall appoint a board of viewers composed of at least three impartial individuals who reside in the vicinity of the area of the drainage association. A member of the board of viewers may not be a landowner. If a drainage project described in a plan is located in more than one county, at least one member of the board of viewers shall be from each county in which the drainage project is located. An individual who is appointed as a member of a board of viewers may not act in that capacity until the individual provides written notice of acceptance of the appointment to the county commissioners or county council. If any member of the board of viewers dies, moves from a county in which the area of the drainage association is located, or otherwise is unable to act, the county commissioners or county council shall appoint a replacement as soon as feasible. The appointment of a replacement does not affect the validity of any work of the board of viewers. Each member of a board of viewers and the engineer is entitled to receive compensation for each day spent on duties as agreed by the county commissioners or county council and the members and engineer appointed under § 26–503 of this subtitle.
