The following terms shall mean:
COMMERCIAL/INDUSTRIAL: Any developed land whereon multiple-family dwellings, commercial retail and office, industrial and manufacturing buildings, storage buildings and storage areas covered with impervious surfaces, parking lots, public and private school buildings, churches, hospitals and convalescent centers have been constructed.
CUSTOMERS OF THE STORMWATER UTILITY: Includes all persons, properties and entities served by and/or benefiting from the utility's acquisition, management, maintenance, extension and improvement of the public stormwater management system and facilities.
DEVELOPED LAND: Land that has been altered from its natural state by construction or installation of more than five hundred (500) square feet of "impervious surface area" as defined in this section.
DUPLEX DWELLING: A building containing only two (2) dwelling units and designed for and occupied exclusively by not more than two (2) families with separate housekeeping and cooking facilities for each. In the application of stormwater service charge rates, duplex dwelling properties shall be treated as two (2) single-family dwellings.
EQUIVALENT RESIDENTIAL UNIT (ERU): The median average impervious coverage of a detached dwelling unit property in the city of Clive as determined by the city, and shall be used as the basis for determining stormwater service charges. Three thousand six hundred sixty seven (3,667) square feet of impervious surface area shall be one equivalent unit.
IMPERVIOUS SURFACE AREA: Those areas which prevent or impede the infiltration of stormwater into the soil as it enters in natural conditions prior to development. Common impervious surface areas include, but are not limited to, rooftops, sidewalks, driveways, patios, parking lots, storage areas, compacted gravel surfaces and other surfaces which prevent or impede the natural infiltration of stormwater runoff which existed prior to development.
MULTIPLE-FAMILY DWELLING: A building or portion thereof containing more than three (3) dwelling units designed for or occupied by more than three (3) families with separate housekeeping and cooking facilities for each. In the application of stormwater service charge rates, multiple-family dwelling properties shall be treated as commercial/industrial.
POLLUTANT: Anything that causes or contributes to pollution. Pollutants may include, but are not limited to: paints, varnishes and solvents; oil and other automotive fluids; nonhazardous liquid and solid wastes and yard wastes; refuse, rubbish, garbage, litter or other discarded or abandoned objects, so that the same may cause or contribute to pollution; pesticides, herbicides and fertilizers; hazardous substances and wastes; sewage, fecal coliform bacteria and pathogens; dissolved and particulate metals; animal wastes; waste and residues that result from constructing a building or structure; and noxious or offensive matter of any kind.
SERVICE CHARGE: The periodic rate, fee or charge applicable to a parcel of developed land, which charge shall be reflective of the service provided by the city of Clive stormwater utility. Service charges are based on measurable parameters which influence the stormwater utility's cost of providing services and facilities, with the most important factor being the amount of impervious surface area on each parcel of developed property. The service charge shall be determined from time to time by resolution of the city council.
SINGLE-FAMILY DWELLING: A building containing only one dwelling unit and designed for and occupied exclusively for residence purposes by only one family.
STORMWATER MANAGEMENT SYSTEMS AND FACILITIES: The issue of drainage management (flooding) and environmental quality (pollution, erosion and sedimentation) of receiving rivers, streams, creeks, lakes and ponds through improvements, maintenance, regulation and funding of plants, structures and property used in the collection, retention, detention and treatment of stormwater or surface water drainage.
SUBSTANTIAL COMPLETION: Represents the date when the construction has been completed and the city of Clive has acknowledged that the construction has been completed in accordance with the approved plans and specifications through the issuance of a temporary certificate of occupancy or permanent certificate of occupancy.
TOWNHOME DWELLING: A dwelling unit which is detached or attached horizontally, and not vertically to one or more other dwelling units, wherein the land or lot beneath each dwelling may be individually owned in common by a townhome association. In the application of stormwater service charge rates, each townhome dwelling shall be treated as one single-family dwelling.
UNDEVELOPED LAND: Land in its unaltered natural state or which has been modified to such minimal degree as to have a hydrologic response comparable to land in an unaltered state shall be deemed undeveloped. "Undeveloped land" shall have less than five hundred (500) square feet of pavement, asphalt or compacted gravel surfaces or structures which create an impervious surface area that would prevent infiltration of stormwater or cause stormwater to collect, concentrate or flow in a manner materially different than that which would occur when the land was in an unaltered natural state. (2000 Code § 102.02)
