BEST MANAGEMENT PRACTICES (BMP): The activities, practices, maintenance procedures, design standards, and other management practices to prevent or reduce the discharge of pollutants directly or indirectly into the waters of the United States. BMPs include treatment requirements, operating procedures, educational activities, and practices to control site runoff spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
CITY: Draper City.
CLEAN WATER ACT (CWA): The federal water pollution control act enacted by Public Law 92-500 as amended by Public Laws 95-217, 95-576, 96-483, and 97-117, enacted 33 USC section 1251 et seq., and subsequent amendments thereto.
CONSTRUCTION ACTIVITY: Activities subject to the Utah pollutant discharge elimination system (UPDES) construction permits including construction projects resulting in land disturbance activities subject to titles 10 and 18 of this code, which include, but are not limited to, clearing and grubbing, grading, excavating, building construction, and demolition.
COUNCIL: The Draper City council.
COUNTY: Salt Lake County or Utah County.
CULVERT: A covered channel or pipe that directs water flow below the ground surface.
CUSTOMER OR PERSON: Any individual, public or private corporation and its officers, partnership, association, firm, trustee, executor of an estate, the state or its departments, institutions, bureaus, agencies, county, city, political subdivision, or any other governmental or legal entity recognized by law.
DEGRADATION: The breakdown, both biological and chemical, of compounds into simpler substances, usually less harmful than the original compound; also the geological wearing down by erosion; or the lowering of the water quality of the watercourse by an increase in the amount of pollutants.
DETENTION: The temporary storage of stormwater runoff for subsequent release.
DETENTION BASIN: A structure or ground surface feature that stores water temporarily and releases it at a controlled rate.
DEVELOPED PARCEL: Any parcel whose surface has been altered by grading, filling, or construction of any improvement.
DEVELOPMENT: Any manmade change to land, including, but not limited to, site preparation, landscaping, filling, grading, paving, excavation and construction.
DISCHARGE: The release of stormwater or other substance from a conveyance system or storage container.
DISTURB: To alter the physical condition, natural terrain, or vegetation of land by clearing, grubbing, excavating, filling, building, or other construction activity.
DRAINAGE: The collection, conveyance, containment, or discharge of ground, surface, and storm water runoff.
EQUIVALENT RESIDENTIAL UNIT OR ERU: The unit of measure used as an index to compare the uses, needs and impact to the storm drain system by different sized properties with different amounts of impervious surface, and is represented by the average single- family residential parcel which is calculated to be equal to three thousand (3,000) square feet of impervious surface area.
EROSION: The wearing away of land surface by wind, water, ice, gravity, or mechanical processes, including vehicular traffic.
HOT SPOT: An area where land use or activities generate highly contaminated runoff with concentrations of pollutants in excess of those typically found in stormwater.
ILLEGAL DISCHARGE: Any direct or indirect nonstormwater discharge to the storm drain system, except discharges from emergency firefighting activities and other discharges exempted in this chapter.
ILLICIT CONNECTION: Any physical connection to the storm drain system allowing discharge of nonstormwater which has not been permitted by the city.
IMPERVIOUS SURFACE: A surface which does not allow water to pass through to the soil and causes water to run off in quantities or speeds greater than under natural conditions, including rooftops, concrete or asphalt paving, walkways, patios, driveways, parking lots or storage areas, and gravel that has been subjected to surface traffic, including compacted gravel surfaces.
INFILTRATION: The downward movement of water from the surface to the subsoil, which capacity is expressed in terms of inches per hour.
INITIAL STORM DRAINAGE SYSTEM: The portions of the stormwater collection system designed to convey stormwater from a ten percent (10%) storm (10-year return period) and may include inlets, piping, curb and gutter, detention basins, or other conveyance channels or facilities and is designed to reduce street maintenance costs, to provide protection against regularly recurring damage from storm runoff of a ten (10) year recurrence interval or less, to help create an orderly system, and to provide convenience to the customer.
INLET: An entrance into a ditch, culvert, storm drain, or other waterway.
LOW IMPACT DEVELOPMENT (LID): A stormwater management approach with a basic principle that is modeled after nature. LID's goal is to mimic a site's predevelopment hydrology by using design techniques that infiltrate, filter, store, evaporate, and detain runoff close to its source.
MAJOR STORM DRAINAGE SYSTEM: The system designed to convey the one percent (1%) storm (100-year return period) which utilizes a combination of the initial storm drainage system and the street right of way for conveyance, thereby reducing damage to homes, buildings, and other structures.
MITIGATION: On site facilities or practices which reduce stormwater quantity or improve stormwater quality.
NONPOINT SOURCE: Pollution caused by diffuse sources rather than a single location such as a pipe, including agricultural or urban runoff.
NONSTORMWATER DISCHARGE: Discharges that are not completely composed of stormwater.
PARCEL: The smallest, separately segregated unit of land having an owner, boundaries and surface area, and is documented with a property number by the county.
POLLUTANT: Any substance introduced into the environment that adversely affects the usefulness of a resource including paints, varnishes, and solvents; oil and other automotive fluids; nonhazardous liquids; solid wastes and yard wastes; refuse, rubbish, garbage, litter, or other discarded or abandoned objects and accumulations so that same may cause or contribute to pollution; floatables; pesticides, herbicides, and fertilizers; hazardous substances and wastes; sewage, fecal coliform and pathogens; dissolved and particulate metals; animal wastes; wastes and residues that result from constructing a building or structure; and noxious or offensive matter of any kind.
PUBLIC WORKS DIRECTOR: The Draper City public works director or the director's designee.
RECEIVING WATER: Bodies of water that receive water from upstream systems.
SINGLE-FAMILY RESIDENTIAL PARCEL: Any parcel of land containing a single-family or duplex dwelling unit.
SOURCE CONTROL: A practice or structural measure to prevent pollutants from entering stormwater runoff or other environmental media.
STATE STORMWATER PERMIT FOR CONSTRUCTION ACTIVITIES: The state required permit issued by the Utah division of water quality to any person or business intending to disturb more than one acre of property or less than one acre if that property was part of a common plan of development or sale since 1992.
STORM DRAIN FACILITIES: Any facility, improvement, development or property made for controlling stormwater quantity and quality.
STORM DRAIN SYSTEM: All initial and major manmade storm drain facilities and conveyances, and natural systems including designated open spaces owned or maintained by the city that store, control, treat, or convey stormwater.
STORMWATER: Water produced by storms, surface drainage, snow and ice melt, and other water handled by the storm drain system.
STORMWATER MAINTENANCE AND PRESERVATION PLAN: A document created to guide the owners of a parcel of land to inspect, document, and maintain any private infrastructure used to contain or redirect stormwater runoff and to prevent pollution from entering the city's drainage system.
STORMWATER POLLUTION PREVENTION MAINTENANCE AGREEMENT (MAINTENANCE AGREEMENT): An agreement between the city and the owner of a parcel of land that requires the owner to implement a stormwater maintenance and preservation plan.
STORMWATER POLLUTION PREVENTION PLAN OR SWPPP: The document which describes the best management practices and activities to be implemented by a person or business to identify sources of pollution or contamination at a site and the actions to eliminate or reduce pollutant discharges to stormwater, storm drain facilities, or receiving waters, and which plan must be prepared prior to obtaining a state stormwater permit for construction activities.
