A. Any such improvement may be initiated either upon petition or by resolution therefor, but such improvement may be ordered only by ordinance.

B. In case the improvement is initiated by petition, such petition shall be presented to and filed with the city clerk, or such other officer as may be designated by the city council. The city engineer shall thereupon examine such petition, determine the sufficiency thereof and ascertain if the facts therein stated are true. And he shall cause an estimate of the cost and expense of such improvement to be made and shall transmit it to the city council, together with all papers and information in his possession regarding it, together with his recommendations thereon and a description of the boundaries of the district and a statement of the proportionate amount of the cost and expense of such improvement which shall be borne by property within the proposed assessment district, and a statement of the actual valuation of the real estate, including 25 percent of the actual valuation of the improvements in such proposed district according to the valuation last placed upon it for purposes of general taxation, together with all other outstanding and unpaid local improvement assessments against the property included in the district, excluding penalties and interest. And, in case the said petition is sufficient, the city engineer shall also submit a diagram showing thereon the lots, tracts or parcels of land and other property which will be specially benefited thereby and the estimated amount of the cost and expense of such improvement to be borne by each lot, tract or parcel of property; provided, that no such diagram shall be required where such estimates are on file in the office of the city engineer, or other designated city office, together with a detailed copy of the preliminary assessment roll and the plans and assessment maps of the proposed improvement.

C. The city council may initiate such improvement directly by resolution declaring its intention to order such improvement and setting forth the nature and territorial extent thereof and notifying all persons who may desire to object thereto to appear and present such objections at a meeting of the city council, or a committee thereof, at the time specified in such resolution. Such resolution shall be published in at least two consecutive issues of the official newspaper of the city, or, if there is no official newspaper, in a newspaper of general circulation within the city, and the date of hearing thereon shall be at least 15 days after the date of the first publication of the same. The city engineer shall submit to the city council, at or prior to the date fixed for such hearing, the same data and information required to be submitted in the case of a petition.

D. Notice of hearing upon such resolution shall be given by mail at least 15 days before the day fixed for hearing to the owners or reputed owners of all lots, tracts and parcels of land or other property to be specially benefited by the proposed improvement, as shown on the rolls of the county treasurer, directed to the address thereon shown. The notice shall set forth the nature of the proposed improvement, the estimated cost, and the estimated benefits of the particular lot, tract, or parcel.

E. The city council may, by ordinance, authorize the making of any such improvement and, in case of an improvement initiated by resolution of the city council, such ordinance may be passed on at any time after the date of the hearing specified in the resolution. (Ord. 84 § 2, 1961)
