(A) Generally. For the purposes stated in § 55.003, there is hereby assessed a storm water service charge for each property owner owning land situated within the corporate limits of the city that contributes directly or indirectly to the storm water system of the city, in an amount as determined below.
(B) Impervious area. For any such property, lot, parcel of land, building or premises which contribute directly or indirectly to the storm water system of the city, such charge shall be based upon the quantity of impervious area situated thereon. Impervious area of public rights-of-way and railroad lines (which shall not be deemed to include adjacent property, such as a rail yard, operated by a railroad), will not be included in the determination of a storm water service charge.
(C) Classification of property. All properties within the city will be assigned an equivalent residential unit (ERU), or a multiple thereof, with all properties having impervious area assigned at least one ERU, as follows.
(1) Single-family residential properties. A monthly flat-rate charge for storm water service rendered to single-family residential properties shall be assessed to each single-family residential parcel within the city limits. All single-family residential properties are hereby assigned one ERU.
(2) Other properties. Properties with impervious area other than those containing a single-family residence will be assigned an ERU multiple based on the total amount of impervious area on the property (measured in square feet) divided by 2,980 square feet. ERU multiples shall be rounded to the nearest whole integer.
(D) Land alterations. The issuance of any building permit or other action which results in a land alteration of a property other than a single-family residential property or a property that currently only contains a single-family residence but will be no longer used for such purpose shall be cause to an adjustment of the storm water service charge determined under this section. The property owner shall have the obligation of informing the Department of any such changes.
(E) Exceptions/exemptions. Except for public rights-of-way and railroad lines, there shall be no exceptions or exemptions from the assignment of gross storm water ERUs for any property with impervious area.
