When the city council determines to proceed to create a drainage district, it shall so declare by resolution, which resolution may state the nature and extent of the drainage improvement to be made and the limits thereof, and may describe the parcel or parcels of land proposed to be taken or condemned, in case condemnation may be required, by any description substantially identifying the same, by lot or block number, or number of front feet, or, if owned by an estate, the name thereof. No error, mistake or omission of such resolution shall invalidate it, and its passage shall be conclusive of the public use and necessity of the proposed improvement. Upon passage of such resolution, the city engineer or an engineer designated by the city council shall prepare and submit to the city council a plat showing the nature and limits of the proposed improvements, the boundaries thereof and the points between which it is proposed to establish the same, and the property through which it is to be extended, which is to be taken or condemned therefor, and shall in writing report the estimated total cost of such improvement, and of each parcel of property to be condemned or acquired. The city council shall examine such plat and report and correct errors therein, if any, but no error or omission shall invalidate the same or any proceeding had thereafter pursuant thereto. (Code 1941, Art. 128-4)
