In all cases where costs of the improvement are to be paid for, in whole or in part, by fixing benefit districts or by means of apportionment of benefits on all property benefited, the assessments shall be levied and collected as the statutes now authorize, or may hereafter authorize the assessment, levy and collection of the expense of public improvements, but such special assessments shall not be any part of the condemnation proceedings.
