As soon as the special tax or special assessment for any such improvement shall have been finally confirmed, as provided by law, and sooner if deemed expedient by the mayor and council, the mayor is authorized to advertise, in one or more newspapers of general circulation printed or published in the city, for proposals to furnish materials and do said work, according to the plans and specifications aforesaid. Such advertisement shall be published at least ten (10) days before the date fixed for opening said proposals, and shall state the nature and extent of the improvement ordered, the place where specifications thereof may be seen, and the time and place when and where the bids will be opened. The right to reject any and all proposals so received shall be reserved in the advertisement. (Ord. 871, 2-17-1981)
