(1) A water quality management fee is imposed on every parcel of land within the water quality management area except the following:
(a) Undeveloped parcels;
(b) Railroad tracks;
(c) State and federal roads;
(d) Urban county government streets and roads;
(e) Private streets which are used exclusively for access to single-family residential parcels.
(2) The following charges are hereby established and imposed for all parcels within the water quality management area, excluding exempted properties:
(a) Class A properties: Single-family residential or farm properties. The single-family residential rate shall be four dollars and thirty-two cents ($4.32) per month for each parcel and the farm property rate shall be four dollars and thirty-two cents ($4.32) per month for each parcel. This flat rate fee is based on each single-family residential parcel or farm property being equal to one ERU. The urban county government shall determine the number of single family residential parcels and farm properties in the water quality management area.
(b) Class B: All other parcels: The charge for all other parcels within the water quality management area shall be based upon the number of square feet of measured impervious surface, as determined by the urban county government through aerial photography and surface feature evaluation processes, expressed in whole ERUs by rounding to the nearest ERU (determined to be two thousand five hundred (2,500) square feet of impervious surface). The charge for Class B properties shall be computed by multiplying the number of ERUs for a given parcel by the unit rate established by the urban county government of four dollars and thirty-two cents ($4.32) per ERU per month but in no event shall any such parcel pay less than four dollars and thirty-two cents ($4.32) per month.
(c) All rates and fees set forth in this section shall be adjustable each July 1 beginning on July 1, 2011, by an amount based upon the Consumer Price Index for All Urban Consumers, the U.S. City Average ("CPI-u") published monthly by the Bureau of Labor Statistics. These rates shall be adjusted up if so indicated by a factor determined by averaging the monthly CPI-u published for the twelve-month period ending, and including, April of the year before the July 1 adjustment.
