LID is an approach to land development or redevelopment that works to manage stormwater close to its source. LID employs principles and techniques used in designing sites (starting from site layout, and grading and compaction phases of construction) that disturb only the smallest area necessary, minimize soil compaction and imperviousness, preserve natural drainages, vegetation and buffer zones, and utilize on-site stormwater treatment techniques. LID sites reduce and compensate for a development's impact(s) on hydrology and water quality. Rather than conventional hardpiping from impervious surfaces, implementing LID principles and practices, stormwater can be managed in a way that reduces the impact of built-up areas and promotes the natural movement of stormwater within an ecosystem or watershed. Applied on a broad scale, LID can support and promote a watershed's hydrologic and ecological functions. |

LID sites reduce and compensate for a development's impact(s) on hydrology and water quality. Rather than conventional hardpiping from impervious surfaces, implementing LID principles and practices, stormwater can be managed in a way that reduces the impact of built-up areas and promotes the natural movement of stormwater within an ecosystem or watershed. Applied on a broad scale, LID can support and promote a watershed's hydrologic and ecological functions. |

OFF-SITE FACILITY: | A stormwater management measure located outside the subject property boundary and described in the application submittal for land development activity. |
ON-SITE FACILITY: | A stormwater management measure located within the subject property boundary and described in the application submittal for land development activity. |
OPERATIONS AND MAINTENANCE (O&M) CONTRACT: | A recorded legally-binding agreement between the City and a BMP Owner that acts as a property deed restriction, and which provides for long term maintenance of stormwater management practices. The O&M Contract serves to document the agreed upon maintenance schedule and commitment by the BMP Owner to perform maintenance. |
PERMIT: | The current National Pollutant Discharge Elimination System (NPDES) General Permit for Discharges from Small Municipal Separate Storm Sewer Systems, (Permit No. NVS040000 at the time of enactment of this Ordinance), issued to the City of Elko and other public entities. |
PERSON: | Any individual, association, organization, partnership, firm, corporation or other entity recognized by law and acting as either the owner or the owner's agent. |
POSTCONSTRUCTION STORMWATER: | A term used to distinguish stormwater practices used during site construction (otherwise known as "construction stormwater" or "erosion and sediment control") from those that are used on a permanent basis to control runoff once construction is complete and a Notice of Termination has been approved by the Nevada Division of Environmental Protection (NDEP). |
POSTCONSTRUCTION STORMWATER QUALITY MANAGEMENT PLAN (PSQMP): | A document which describes the BMPs and activities to be implemented by a person or business at a development to preserve the integrity of the MS4, waters of the United States and watercourses, including maintenance and protection of the physical, biological, and chemical qualities of watercourses; to prevent an increase in the rate of stormwater runoff; to minimize any increase in stormwater runoff volume; to minimize impervious (i.e. paved) areas; to maximize the protection of existing drainage features and existing vegetation; to minimize land clearing and grading; to minimize soil compaction; and to use other structural or nonstructural BMPs that prevent or minimize changes in stormwater runoff. As used in this Chapter, a PSQMP shall be equivalent to and shall meet the requirements applicable to an "operations and maintenance plan" as that term is used in the BMP Manual. |
PROJECT: | An NDSR or any "project" listed in Subsection 3.2.1 (Project Applicability) (together with any amendments thereto) of the BMP Manual. |
RECHARGE: | A hydrologic process where water moves downward from surface water to groundwater. |
REDEVELOPMENT: | Development, rehabilitation, expansion, or demolition that disturbs the ground surface or increases the impervious area on a previously developed or disturbed site. |
RESPONDENT: | A person to whom a notice of violation, citation or notice of civil infraction has been issued pursuant to this chapter or a person who is formally accused by the City of violating this chapter. The term "respondent" shall include any person defending a notice of violation, citation, notice of civil infraction or complaint issued on the basis of a violation of this chapter or who is otherwise subject to any punitive measure pursuant to this chapter. |
REVEGETATION: | The recreation of plant communities that cannot be easily distinguished from the healthy native plant communities surrounding them or in their general proximity. |
SOURCE CONTROL: | Techniques that aim to reduce the quantity and improve the quality of stormwater at or near its source by using infrastructure, natural physical resources or changes in practices. |
STORMWATER: | Any surface flow runoff, and drainage consisting entirely of water from any form of natural precipitation, and resulting from such precipitation. |
STORMWATER BMP: | A generic term used interchangeably with "stormwater practice" or "stormwater treatment practice." Stormwater BMPs can be either "structural" or "nonstructural." |
STORMWATER CONVEYANCE SYSTEM: | Publicly owned facilities by which stormwater is collected and/or conveyed, including, but not limited to, any roads with drainage systems, municipal streets, gutters, curbs, inlets, piped storm drains, pumping facilities, retention and detention basins, natural and humanmade drainage channels, reservoirs and any other drainage structures. |
STORMWATER MANAGEMENT: | The use of structural or nonstructural practices that are designed to reduce stormwater runoff pollutant loads, discharge volumes, peak flow discharge rates and detrimental changes in stream temperature that affect water quality and habitat. |
STORMWATER MANAGEMENT PROGRAM (SWMP): | A comprehensive program to manage the quality of stormwater discharged from the MS4. |
STORMWATER TREATMENT DEVICE: | An invention, contrivance or machine designed to capture pollutants and contaminants from surface water runoff before they reach the MS4, waters of the United States, a watercourse or a body of water. |
STRUCTURAL BMPS OR STRUCTURAL TREATMENT CONTROLS: | Public domain treatment controls or manufactured (proprietary) treatment controls. Public domain treatment controls are those that can be designed by an engineer and have been implemented and tested by numerous communities through the nation. Manufactured (proprietary) treatment controls are patented devices that have been engineered and constructed by private companies. In either case, engineering plans must be developed. A list of structural BMPs is shown in Table 7-1 of the BMP Manual (together with any amendments thereto). A list of manufactured (proprietary) treatment controls is shown in Table 8-1 of the BMP Manual (together with any amendments thereto). |
WATER QUALITY VOLUME (WQv): | The storage needed to capture and treat ninety percent (90%) of the average annual stormwater runoff volume. Numerically, WQv will vary as a function of long term rainfall statistical data. |
WATERCOURSE: | Any drainage or structure through which water may pass or drain and any body of water, including, but not limited to, lakes, ponds, rivers, streams, and bodies of water which have been delineated by federal, state, or local agencies in accordance with federal, state, or local laws. |
