Stormwater management plan means the set of drawings and other documents that comprise all the information and specifications for the programs, drainage systems, structures, BMPs, concepts and techniques intended to maintain or restore quality and quantity of stormwater runoff to pre-development levels.
Stormwater runoff means water flow on the surface of the ground or in storm sewers, resulting from precipitation.
Stormwater system means constructed and natural features which function together as a system to collect, convey, channel, hold, inhibit, retain, detain, infiltrate, divert, treat, or filter stormwater. “Stormwater system” includes both public and privately owned features.
Stormwater management system means any equipment, plants,
Storm water management plan means a comprehensive plan designed to reduce the discharge of pollutants from storm water after the site has under gone final stabilization following completion of the construction activity.
Stormwater Pollution Prevention Plan or "SWPPP" means a document that is prepared in accordance with good engineering practices and that identifies potential sources of pollutants that may reasonably be expected to affect the quality of stormwater discharges from the construction site, and otherwise meets the requirements of this Ordinance. In addition the document shall identify and require the implementation of control measures, and shall include, but not be limited to the inclusion of, or the incorporation by reference of, an approved erosion and sediment control plan, an approved stormwater management plan, and a pollution prevention plan.
Stormwater management planning area means the geographic area for which a stormwater management planning agency is authorized to prepare stormwater management plans, or a specific portion of that area identified in a stormwater management plan prepared by that agency.
Stormwater means water resulting from precipitation (including rain and snow) that runs off the land’s surface, is transmitted to the subsurface, or is captured by separate storm sewers or other sewage or drainage facilities, or conveyed by snow removal equipment.
Stormwater management planning agency means a public body authorized by legislation to prepare stormwater management plans.
Wastewater System means a system of wastewater collection, treatment,
Stormwater management BMP means an excavation or embankment and related areas designed to retain stormwater runoff. A stormwater management BMP may either be normally dry (that is, a detention basin or infiltration system), retain water in a permanent pool (a retention basin), or be planted mainly with wetland vegetation (most constructed stormwater wetlands).
Stormwater management means the programs to maintain quality and quantity of stormwater runoff to pre-development levels.
Virginia Stormwater Management Program or “VSMP” means a program approved by the State Board after September 13, 2011, that has been established by a locality to manage the quality and quantity of runoff resulting from land-disturbing activities and shall include such items as local ordinances, rules, permit requirements, annual standards and specifications, policies and guidelines, technical materials, and requirements for plan review, inspection, enforcement, where authorized in this article, and evaluation consistent with the requirements of this article and associated regulations.
Storm water or wastewater collection system means piping, pumps, conduits, and any other equipment necessary to collect and transport the flow of surface water run-off resulting from precipitation, or domestic, commercial, or industrial wastewater to and from retention areas or any areas where treatment is designated to occur. The collection of storm water and wastewater does not include treatment except where incidental to conveyance.
Transportation project means any project that the department is authorized by law to undertake including but not limited to a highway, tollway, bridge, mass transit, intelligent transportation system, traffic management, traveler information services, or any other project for transportation purposes.
Wastewater facilities means the structures, equipment, and processes required to collect, carry away, and treat domestic and industrial wastes and dispose of the effluent.
Stormwater management measure means any practice, technology, process, program, or other method intended to control or reduce stormwater runoff and associated pollutants, or to induce or control the infiltration or groundwater recharge of stormwater or to eliminate illicit or illegal non-stormwater discharges into stormwater conveyances.
Stormwater management facility means a control measure that controls stormwater runoff and changes the characteristics of that runoff including, but not limited to, the quantity and quality, the period of release or the velocity of flow.
Wastewater treatment plant means a facility designed and constructed to receive, treat, or store waterborne or liquid wastes.
Public water supply system means a system for the provision to the public of piped water for human consumption, if the system has at least fifteen service connections or regularly serves at least twenty-five individuals. The term includes any source of water and any collection, treatment, storage, and distribution facilities under control of the operator of the system and used primarily in connection with the system, and any collection or pretreatment storage facilities not under such control which are used primarily in connection with the system.
Virginia Stormwater Management Program authority or "VSMP authority" means an authority approved by the State Board after September 13, 2011, to operate a Virginia Stormwater Management Program.
Drainage system means one or more artificial ditches, tile drains or similar devices which collect surface runoff or groundwater and convey it to a point of discharge.
Wastewater means the spent water of a community. From the standpoint of source, it may be a combination of the liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions, together with any groundwater, surface water, and storm water that may be present.
