(a) The volume, rate and pollutant loading of Stormwater runoff discharged from a given lot or parcel of real property to the City's structural and natural stormwater drainage systems and facilities is directly related to the Impervious Surface Area on that lot or parcel. Therefore, Impervious Surface Area shall be the primary parameter for establishing a rate structure to distribute the cost of services associated with the Utility and its Stormwater Management Programs and the operation, maintenance, repair, improvement and extension of its Stormwater Drainage Facilities through a schedule of rates, fees, charges and penalties related to the operation of the Utility.
(b) Based on an analysis by the City of Impervious Surface Area on certain sampled single family residential real properties throughout the City, an Impervious Surface Area of 3,500 square feet was determined to be the average amount of Impervious Surface Area of a typical single family residential property in the City and is hereby designated as one (1) Equivalent Residential Unit (ERU).
