A. 
The amount of a particular stormwater utility charge may be appealed to the City Engineer by filing a written appeal with the City Clerk/Treasurer prior to the due date of the charge or within 30 days of payment. The written appeal shall specify all grounds for challenge to the amount of the charge and shall state the amount of charge that the appellant considers to be inappropriate. Failure to timely appeal waives all rights to later challenge the charge.
B. 
In considering an appeal, the City Engineer shall determine whether the stormwater utility charge is fair and reasonable under the particular facts and circumstances pertaining to that specific property and, in the event the appeal is granted, whether or not a refund is due the appellant and the amount of the refund. The City Engineer shall notify the appellant in writing of their determination.
C. 
The customer has 30 days from the date of the written decision of the City Engineer to file a written appeal with the Board of Public Works.
D. 
If the Board of Public Works determines that a refund is due the customer, the refund will be applied as a credit towards the customer's next stormwater billing charge, if the refund will not exceed the customer's next stormwater billing charge, or it may be refunded at the discretion of the Board of Public Works.
A. 
The Common Council hereby finds and determines that the stormwater utility charges established under this division reasonably reflect the services rendered to real property and may be, and are hereby authorized to be, assessed, charged, levied, imposed and collected upon property as a special charge in accord with all applicable Wisconsin Statutes.

The mailing of the bill for stormwater utility charges to a property owner shall serve as notice to the property owner that failure to pay the charges when due may result in the charges being levied upon the owner's applicable real property.
