Each of the benefited properties shall be assessed for a proportional share of the costs to the city of constructing the public improvements. The proportion shall be determined by the council by resolution but shall be based on the level of benefit which the council determines is applicable to that parcel of benefited property compared to the level of benefit received by the other benefited properties. The level of benefit to a property may be higher for more intense uses, such that a fee for a single-family use on one property would be lower than a multifamily use on that same property. The city council may determine that each of the parcels are benefited equally from the public improvements, in which case the fraction shall be one divided by the total number of properties which are determined to be benefited properties. The fee shall be payable at the time of the application for approval of a development project on the benefited property as more fully identified in the resolution setting the amount of the fee. (Ord. 415 §1, 1997).
