Section 15-6-428 - Reassessments; ordinance; roll; effect of contracts or irregularities; limitation; payment(a) The governing body of any city or town shall proceed with any assessment authorized by W.S. 15-6-427 by ordinance so ordering and directing the preparation of an assessment roll. The roll may include any property specially benefited by the improvement, whether or not it was included in the original assessment district. When assessed the additional property becomes a part of the local improvement district, and all payments of assessments shall be paid into the local improvement fund to pay for the improvement.(b) The fact that the contract has been let or that the improvement has been made and computed in whole or in part does not prevent the making of the assessment. The omission, failure or neglect of an officer to comply with the provisions of law or ordinance of the city or town, as to any matter connected with the improvement and the first assessment thereof does not invalidate or in any other way affect the making of any assessment authorized by W.S. 15-6-427. However, the assessment shall not exceed the actual cost and expense of the improvement, together with the accrued interest thereon, and the cost of the reassessment. It is the intent of this chapter to make the cost and expense of local improvements payable by the property specially benefited thereby, notwithstanding that the proceedings of the governing body, board of public works or other board, officers or authority of the city or town may be found irregular or defective, whether jurisdictional or otherwise. When the assessment is completed, all sums paid on the former attempted assessment shall be credited to the property for which they were paid.(c) If any property within the original local improvement district is not affected by any assessment authorized by W.S. 15-6-427, it need not be entered upon the assessment roll.(d) After certification of the roll to the treasurer of the city or town for collection, the same time for payment of assessments, without the imposition of any penalties or interest, and the notice that the assessments are in the hands of the treasurer for collection, shall be given as in the case of an original assessment. After delinquency the penalty and interest shall be charged as on original assessment. If the original assessment was payable in installments, the new assessment, after delinquency, may be divided into equal installments and made payable as the governing body may prescribe in the ordinance ordering the new assessment.
