The monthly charge for nonsingle-family parcels shall be based upon the following formula: BASE RATE + (TNESU * RATE) = Storm Drainage Charge, where TNESU = Total number of equivalent service units contained on the parcel. An equivalent service unit has been determined to be 2,600 square feet of impervious surface, or any fraction thereof as defined in ACC 13.48.110. _C~. Un~.~_eveloped Parcels.
