§ 178. Assessment of cost.

After any such improvement is completed and the cost ascertained, council shall, by ordinance, assess upon the property mentioned, and in the manner provided in the preliminary resolution, the entire cost and expense thereof, excepting the portion to be paid by the city. Such assessment as to each lot or parcel shall be in the proportions fixed in the estimated assessment as reported by the chief engineer, or as revised by the board of revision, and such ordinance shall also state the credits or deductions to which any lot or parcel is entitled, as fixed in such report or revision. The remainder of the cost, together with such credits and deductions, shall be the city's share, and if it exceed the amount originally appropriated, a supplementary appropriation shall be made to cover such excess. Such cost shall include the cost of preliminary and other surveys, the cost of construction, the expense of printing and serving notices, interest on bonds issued to provide funds for such improvement, and any other necessary expenditures connected with said improvement.
