A. The Council finds that all real property in the City contributes to runoff and either uses or benefits from the stormwater system. Therefore, except as otherwise provided in this section, all users of the stormwater system in the City shall pay the service charge established under this chapter for use of the system.

B. A stormwater system user is not required to pay the service charge if the user demonstrates to the satisfaction of the City Engineer, in their sole discretion, that the user does not discharge stormwater to the system during the 100 year, 24-hour design storm event as defined by the State of Oregon. All costs associated with proving this exemption will be borne by the user.

C. Where the City is the user or stormwater customer, there shall be no service charge payable.

D. Undeveloped property. Property is considered undeveloped if there are no structures on the property and no impermeable surfaces.
