§ 34-363. Definitions.

The following words, terms and phrases, when used in this division, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:

Customer means a person in whose name service is rendered as evidenced by the signature on the application/contract for stormwater, sanitary sewer or water service, or in the absence of a signed instrument, by the receipt and payment of bills regularly issued in his name.

Developed means an area which has been altered by grading or filling of the ground surface, or by construction of any improvement or other impervious surface area, which affects the hydraulic properties of the location.

Duplex means a single building which contains two single-family units and shall be calculated as one ERU per unit.

Equivalent Residential Unit (ERU) means an area which is estimated to place approximately equal demand on the city's storm drainage system as a single-family unit. One ERU shall be equal to 3,250 square feet of impervious surface.

High intensity residential means residential properties that have an ERU value established based on measured impervious surface area. High intensity residential properties are designated as multifamily housing and include four or more units.

Impervious surface means any surface area which either prevents or retards saturation of water into the land surface, or a surface which causes water to run off the land service in greater quantities or at an increased rate of flow from that present under natural conditions pre-existent to development. Common impervious surfaces include, but are not limited to, rooftops, concrete or asphalt sidewalks, walkways, patio areas, driveways, parking lots or storage areas, graveled, oiled or macadam surfaces or other surfaces which similarly impede the natural saturation or runoff patterns which existed prior to development.

Light intensity residential means properties that are equivalent to one ERU per unit and are classified as a single-family unit, duplex or triplex.

Single Family Unit (SFU) means that part of a building or structure which contains one or more rooms with bathroom and kitchen facilities designed for occupancy by one family and where the units are sold and deeded as individual units. A SFU is presumed to have 3,250 square feet of impervious surface area for the purposes of this chapter.

Stormwater means water from precipitation, surface or subterranean water from any source.

Stormwater system means any structure or configuration of ground that is used to accumulate or direct the flow of stormwater, or by its location becomes a place where stormwater flows or is accumulated, including but not limited to pipes, sewers, curbs, gutters, manholes, catchbasins, ponds, open drainageways and their appurtenances.

Triplex means a single building which contains three single-family units and shall be calculated as one ERU per unit.
