For the purposes of this chapter the following definitions shall apply unless the context clearly indicates or requires a different meaning.

CHANNEL. A natural or artificial watercourse
with a definite bed and banks that conducts continuously or periodically flowing water.
DEDICATION. The deliberate appropriation of
property by its owner for general public use.
DETENTION. The temporary storage of storm
runoff in a stormwater management practice with the goals of controlling peak discharge rates and providing gravity settling of pollutants.
DETENTION FACILITY. A detention basin or
alternative structure designed for the purpose of temporary storage of stream flow or surface runoff and gradual release of stored water at controlled rates.
DEVELOPER. A person who undertakes land
disturbance activities.
DRAINAGE EASEMENT. A legal right granted
by a landowner to a grantee allowing the use of private land for stormwater management purposes.
EROSION AND SEDIMENT CONTROL PLAN. A plan that is designed to minimize the accelerated erosion and sediment runoff at a site during construction activities.
FEE IN LIEU. A payment of money in place of
meeting all or part of the stormwater performance standards required by this chapter.
HOTSPOT. An area where land use or activities
generate highly contaminated runoff, with concentrations of pollutants in excess of those typically found in stormwater.
HYDROLOGIC SOIL GROUP (HSG). A
Natural Resource Conservation Service classification system in which soils are categorized into four runoff potential groups. The groups range from "A" soils, with high permeability and little runoff production, to "D" soils, which have low permeability rates and produce much more runoff.
IMPERVIOUS COVER. Those surfaces that
hinder the infiltration of rainfall (e.g., building rooftops, pavement, sidewalks, driveways, etc).
INDUSTRIAL STORMWATER PERMIT. A
National Pollutant Discharge Elimination System permit issued to a commercial industry or group of industries which regulates the pollutant levels associated with industrial stormwater discharges or specifies on-site pollution control strategies.
INFILTRATION. The process of percolating
stormwater into the subsoil.
INFILTRATION FACILITY. Any structure or
device designed to infiltrate retained water to the subsurface. These facilities may be above grade or below grade.
JURISDICTIONAL WETLAND. An area that is
inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support a prevalence of vegetation typically adapted for life in saturated soil conditions, commonly known as hydrophytic vegetation.
LAND DISTURBANCE ACTIVITY. Any
activity which changes the volume or peak flow discharge rate of rainfall runoff from the land surface. This may include the grading, digging, cutting, scraping, or excavating of soil, placement of fill materials, paving, construction, substantial removal of vegetation, or any activity which bares soil or rock or involves the diversion or piping of any natural or man-made watercourse.
LANDOWNER. The legal or beneficial owner
of land, including those holding the right to purchase or lease the land, or any other person holding proprietary rights in the land.
MAINTENANCE AGREEMENT. A legally
recorded document that acts as a property deed restriction, and which provides for long-term maintenance of stormwater management practices.
MS4. Municipal separate storm sewer system.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) STORMWATER DISCHARGE PERMIT. A permit issued by EPA (or by a state under authority delegated pursuant to 33 USC § 1342(b)) that authorizes the discharge of pollutants to water of the United States, whether the permit is applicable on an individual, group, or general area-wide basis.
NONPOINT SOURCE POLLUTION. Pollution
from any source other than from any discernible, confined, and discrete conveyances, and shall include, but not be limited to, pollutants from agricultural, forestry, mining, construction, subsurface disposal and urban runoff sources.
OFFSET FEE. A monetary compensation paid
to a local government for failure to meet pollutant load reduction targets.
OFF-SITE FACILITY. A stormwater
management measure located outside the subject property boundary described in the permit application for land development activity.
ON-SITE FACILITY. A stormwater
management measure located within the subject property boundary described in the permit application for land development activity.
PERSON. Any individual, partnership,
co-partnership, firm, company, corporation, association, trust, estate, political subdivision, state agency, or any other legal entity or their legal representative, agent or assigns legally capable of owning property in the state.
POLLUTANT. Something that causes or
contributes to pollution. 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, ordinances, 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 or building or structure; sediments and noxious or offensive matter of any kind.
RECHARGE. The replenishment of
underground water reserves.
REDEVELOPMENT. Any construction,
alteration or improvement exceeding 2,000 square feet in areas where existing land use is high density, commercial, industrial, institutional, or multi-family residential.
RIPARIAN ZONE. The area along water bodies
that serve as interfaces between terrestrial and aquatic ecosystems.
RUN-OFF. The portion of the precipitation from
such sources as rainfall, snowmelt, or irrigation water that flows over the ground surface.
SITE. The entire area included in the legal
description of the land on which land-disturbing activity has been proposed in the permit application.
STOP WORK ORDER. An order issued which
requires that all construction activity on a site be stopped.
STORMWATER MANAGEMENT. The use of
structural or non-structural 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 RETROFIT. A stormwater
management practice designed for an existing development site that previously had either no stormwater management practice in place or a practice inadequate to meet the stormwater management requirements of the site.
STORMWATER RUNOFF. Flow on the surface
of the ground, resulting from precipitation.
STORMWATER TREATMENT PRACTICES (STPs). Measures, either structural or nonstructural, that are determined to be the most effective, practical means of preventing or reducing point source or non-point source pollution inputs to stormwater runoff and water bodies.
SWALE. A grassy depression in the ground
designed to collect stormwater runoff from streets, driveways, rooftops and parking lots.
WATER QUALITY VOLUME (WQv). The
storage needed to capture and treat 90% of the average annual stormwater runoff volume. Numerically, WQv will vary as a function of long term rainfall statistical data.
WATERCOURSE. A permanent or intermittent
stream or other body of water, either natural or man-made, which gathers or carries surface water.
