A. The storm water SDC is based upon existing or intended use of the property at the time of application for connection. If the property is improved, expanded, subdivided, or otherwise modified or use is increased by more than 10 percent, so as to increase the storm water SDC due for that property or structure, a storm water SDC shall be charged for the modified portion of the property or structure based on the storm water SDC schedule in effect at the time of the modification.

B. The storm water SDC paid for a specific storm water service for a residential, commercial, or industrial unit shall be valid for a one-year period from the date of issuance of the storm water permit. After the one-year period, the storm water permit will have expired if there has been no development. The city manager will then, in writing, notify the permittee that the permit has expired. The written notification of storm water permit expiration shall state the permittee has 10 days from the receipt of the expiration notice to request an extension time of the storm water permit. If there has been no response within 10 days of notification, the SDC shall be considered forfeited. The permittee shall then be required to reapply for a storm water connection permit and pay the storm water SDC in effect at the time of reapplication. [Ord. 789 Art. 9; Ord. 731 Art. 8.]
