918.09   ADJUSTMENTS.
   (a)   In the event the amount of impervious area on a nonresidential property is decreased or increased above that assigned by the Department of Utilities, an adjustment may be made to the ERU multiple assigned to the property to properly reflect the adjusted amount of impervious area. The new ERU multiple shall be billed from the date on which the Department mails a notification of the change to the owner of the property.
   (b)   If the Department of Utilities finds that it has been under or over billing a nonresidential property as a result of the increase in impervious area, the owner will receive notification from the City that an adjustment is being made to the property's ERU multiple. In the event that over billing has occurred, a refund of the difference between the corrected amount and the over-billed amount shall be credited to the account for a maximum of the previous 12 months. The owner shall not be penalized for the under-billing.
   (c)   In the event that the runoff from a parcel does not drain into any of the City's drainage watersheds or systems, the parcel shall only be charged the stormwater monitoring portion of the ERU per Section 918.05(c). Such adjustments shall be made when the owner submits an appeal of the ERU assignment.
