The necessity for such sewer and water connections shall be determined by the City Manager. Such determination shall be based upon the size, shape and area of each abutting lot or parcel of land, the lawful use of such land under the Zoning Code, the character of the locality and the probable future development of each abutting lot or parcel of land. The Manager shall give written notice of the intention to install such sewer and water connections and to charge the cost of the same to the premises, to each owner of the land abutting the street, to be furnished with such connections, as shown by the records of the City Assessor. Any owner objecting to the installation of any such sewer or water connection shall file his or her objections, in writing, within seven days after service of such notice, with the Manager who shall, after considering each such objection made in writing, make a final determination of the sewer and water connections to be installed.
