The board of commissioners of any drainage district, or the board of directors of any irrigation district, in the state of Idaho, shall have the power to cancel, compromise, and/or extend the time for the payment of delinquent district assessments levied on lands within the district, where such district is refunding and reducing its outstanding indebtedness by agreement, through any governmental agency of the United States, or otherwise. Said cancellation, compromise, and/or extension of time for the payment of such delinquent taxes shall take effect if and when the refunding and reduction of said indebtedness is completed, or at least ninety per cent (90%) completed. When the refunding and reduction of said indebtedness is completed, or at least ninety per cent (90%) completed, said board shall cause appropriate notation of said cancellation, compromise and/or extension of time for payment to be noted upon the proper records, and in the event said assessments are collected by county officers, said board shall transmit certified copies of the orders or resolutions providing for such cancelation, compromise, and/or extension of time for payment to the county auditor and the county tax collector, who shall make appropriate notation thereof upon the proper records. Provided, however, that the provisions of this section shall not be applicable in cases where such district has assigned its right to tax deed under the provisions of section 43-715, Idaho Code.
