§ 51.28 RATES.
   The Utility is directed to prepare a list of all lots and parcels within the city and assign a classification as set forth in § 51.26 to each. All properties included in Class C shall be assigned an ARN and IDF. The Utility shall report, to the City Manager, any applications of the provisions of §§ 51.25 through 51.27, which the Utility considers unjust or inequitable, and the matter shall be resolved in accordance with the provisions of § 51.30. Where agreements exist, prior to the adoption of this chapter, between the city and a developer fixing rates for lots and parcels, such rates shall be applied by the Utility in lieu of the provisions of this chapter until the agreements are terminated or the terms therein are otherwise no longer valid. The rates for the two classes of property shall be as follows:
   (A)    Class R. The monthly stormwater management service charge for Class R lots and parcels shall be $3.
   (B)    Class C. The monthly stormwater management service charge for Class C lots and parcels shall be calculated as follows, but shall not be less than the monthly stormwater management service charge for Class R lots and parcels:
      Multiply the ARN of each lot or parcel times the IDF of the lot or parcel. Divide this figure by the typical Class R property ARN and IDF. Multiply this figure times the monthly charge per Class R property. This calculation may be phrased as follows:
   (ARN) X (IDF) X ($3.00) = $   Monthly Stormwater
    (5) X (.25)            Management Service Charge
