For the purposes of this ordinance, the following shall mean:
Best Management Practices (BMPs):Includes schedules of activities, prohibitions of 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 also include treatment requirements, operating procedures, educational activities, and practices to control plant site run-off spillage or leaks, sludge or waste disposal, or drainage from raw material storage. A list of acceptable BMPs can be found in Springville's Specifications and Drawings.
City:The City of Springville, Utah County, Utah.
City Engineer:The City of Springville's Chief Engineer or his or her designee.
City Standards and Specifications:The Springville City Standard, Specifications and Drawings, as prepared by Springville City and JUB Engineers, Inc., dated April 2007, and all amendments thereto.
Clearing and Grubbing:Moving, removing, displacing and/or stockpiling, by manual or mechanical means, trees, and other vegetation and/or the top organic layer as described in the geotechnical report. In the absence of a geotechnical report the organic layer shall not be greater than eight inches (8").
Detention:Storm water detention is temporary storage of a storm water runoff volume for subsequent release.
Detention Basin:A depression to detain or slow down the flow of storm water until downstream facilities has sufficient flow capacity to handle the flow. A detention basin consists of an inlet, an outlet, the storage basin itself and piping between. The intent of the design of the basin and its improvements are that it is to be designed and improved in such a way as to be an asset to the neighborhood and community.
Development:Any man-made change to the land, including but not limited to, site preparation, filling, grading, paving, excavation and construction of building(s) or other structures.
Discharge:The release of storm water 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:Refers to the collection, conveyance, containment and/or discharge of surface and storm water run-off.
Enforcement Authority:The City Engineer, the Engineering Inspector, and other designated representatives of the City Engineer, or any duly appointed Code Enforcement Officer or police official charged with the responsibility for enforcement of the provisions of this Chapter.
Erosion:The wearing away of land surface by wind, water, ice, gravity or mechanical processes, including vehicular traffic. Erosion occurs naturally from weather or run-off but can be intensified by land-clearing practices related to farming, residential or industrial development, road building, clearing of vegetation or recreational activities including OHV use, hiking, equestrian, etc.
Fill:A deposit of earth material placed by artificial means.
Final Stabilization:All construction and disturbance activities at the site for which the land disturbance permit was issued have been completed and a uniform perennial vegetative cover with a density of seventy percent (70%) of the cover for unpaved areas not covered by permanent structures has been established or equivalent permanent stabilization measures as approved by the City Engineer have been employed.
Grading:The cutting and/or filling of the land surface to a desired slope or elevation.
Illegal Discharge:Any direct or indirect non-storm water discharge to the storm drain system, except discharges from fire fighting activities and other discharges exempted in this ordinance.
Illicit Connection:Any physical connection to a publicly maintained storm sewer system allowing discharge of non-storm water which has not been permitted by the public entity responsible for the operation and maintenance of the system.
Inlet:An entrance into a ditch, storm sewer, or other waterway.
Land Disturbance:Any disturbance of native soils, plants, or environment, including, but not limited to, clearing, grubbing, grading, excavation, filling, dredging, construction of earth-filled dams, and any other types of earthwork.
Landmark Trees:Trees that have a trunk that measures over three inches (3") thick.
Non-point Source:Pollution caused by diffuse sources (not a single location such as a pipe) such as agricultural or urban run-off.
NPDES Permit:An authorization, license or equivalent control document issued by EPA or an approved state agency to implement the requirements of the NPDES program.
On-site:The entire property that includes the proposed development.
Pollutant:Generally, any substance introduced into the environment that adversely affects the usefulness of a resource. Pollutants may include, but are not limited to: paints, varnishes and solvents; oil and other automotive fluids; non-hazardous liquid and 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.
Receiving Waters:Bodies of water or surface water systems that receive water from upstream constructed (or natural) systems.
Retention:The holding of run-off in a basin without release except by means of evaporation, infiltration, or emergency bypass.
Riparian:A relatively narrow strip of land that borders a stream or river.
Storm Drain:A slotted opening leading to an underground pipe or open ditch for carrying surface run-off.
Storm Sewer System:A system of surface and underground conveyance, consisting of curb and gutter, street surface, inlet and clean-out boxes, piping, open channels and detention basins, ditches, channels, storm drains, owned and operated by the City or private owners, which is designed and used to convey or collect storm water.
Storm Water:Any flow that occurs during or following any form of natural precipitation. Storm water includes only the portion of such flow that is composed of precipitation.
Storm Water Pollution Prevention Plan (SWPPP):A 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 storm water, storm sewer systems, and/or receiving waters. This plan must be prepared prior to obtaining a land disturbance permit.
Sump:A formalized underground structure, surrounded by drain rock that acts as a detention basin to allow the slow release of water into the surrounding sub-soil. Sumps usually receive storm water runoff from paved areas such as streets, parking lots, building roofs, etc.
