(A) At the time that the board of county commissioners reviews the permanent base of an improvement for maintenance fund assessments after six annual maintenance fund assessments have been made as provided in section 6137.11 of the Revised Code, the board may request the county engineer to estimate the construction cost of the improvement if that improvement were to be constructed at the time of the permanent base review. Not less than thirty days prior to a hearing at which the board will consider the estimate as the construction cost of the improvement, the clerk of the board shall send to each owner that would be affected a notice by certified mail, return receipt requested, or by first class mail in a five-day return envelope. For each improvement, all individual notices shall be sent by the same type of mail. Whichever method the board chooses, the words "legal notice" shall be printed in plain view on the face of the envelope. The notice shall state the amount of the present permanent base for maintenance assessment, the proposed new permanent base amount with respect to the owner, and the date of the hearing on the proposed change.

(B) The board of county commissioners, by adoption of a resolution at the hearing required under division (A) of this section, may approve the estimate as the construction cost of the improvement in lieu of the original construction cost of the improvement. If approved, the estimate of construction cost shall be the permanent base that is used to calculate maintenance fund assessments for owners benefiting from the improvement. The approved estimate of construction cost shall serve as the permanent base for the purposes of this chapter until such time as it is revised in accordance with this section.
