There is hereby established the following uniform schedule of rates for the services and use of facilities of the storm water management system by the owner, tenant or occupant of the premises using the services and facilities of said system:
   (A)   The City Council shall hereby establish reasonable rates for storm water management systems for each residential dwelling unit; each residential dwelling unit shall be billed a flat fee established by the City Council. An EQUIVALENT RESIDENTIAL UNIT is hereby defined as the statistical average horizontal impervious area of residential dwelling units in the city.
   (B)   For all residential and nonresidential properties, i.e., enterprise, business establishment, building or other occupancy not covered by divisions (A) and (B) of this section, the rate shall be computed based on the total impervious area of the property divided by the average impervious area of an equivalent residential unit times the rate established for an equivalent residential unit. The billing amount shall be updated by the Engineering Department based on any additions to the impervious areas as approved through the building permit process.
   (C)   The rates to be charged for the storm water user fee for equivalent residential unit shall be $3.50 per month.
   (D)   The rates to be charged for nonresidential properties, i.e., all other occupants other than provided for in division (A) of this section, shall be the rate established in division (C) of this section ($3.50), multiplied by the number of equivalent residential units. The equivalent residential unit equals the total square footage of impervious area of the property divided by 2,615 square feet (statistically developed average for all the residential dwelling units in the city). Equivalent residential units will be rounded to the nearest tenth (0.1) of a unit.
   (E)   The rates to be charged for all residential dwelling units will be determined by multiplying 1.0 ERU by the fee for an ERU established in division (C) of this section.
   (F)   The foregoing rates shall become effective for bills due on or after March 1, 2004 without penalty.
