   For the purpose stated in this chapter, there is hereby charged to each utility user and property, lot, parcel of land, building or premises (collectively “properties”) situated within the corporate limits of the City, that is tributary directly or indirectly to the stormwater system, stormwater utility charges determined as provided in this section.

    All improved single-family residential properties are assigned one ERU. A flat rate will apply to all single-family residential properties. All improved single-family residential properties are determined to include impervious areas typical of a single-family residence.
    All properties having an impervious area which are not improved single-family residential properties are to be assigned by the City Manager an ERU multiple based upon eighty percent of the properties' estimated impervious area (in square feet) divided by 2,530 square feet (one ERU). This division will be calculated to the second decimal place.
    The stormwater utility charge shall be four dollars ($4.00) per month per Equivalent Residential Unit (ERU), which shall be effective January 1, 2011, through December 31, 2011. After December 31, 2011 the stormwater utility charge shall be four dollars and twenty-five cents ($4.25) per month per Equivalent Residential Unit (ERU) which shall be effective from January 1, 2012 through December 31, 2012. After December 31, 2012, the stormwater utility charge shall be four dollars and fifty cents ($4.50) per month per Equivalent Residential Unit (ERU).

Such fee shall be increased by three percent for each of the years following 2001. The rate for water supplied by the Municipality for all customers shall be as follows:
