All words used in this chapter shall have their customary meanings, and as defined in Rainwater and Land Development, except those specifically defined in this Section.
(a) Acre: A measurement of area equaling 43,560 square feet.
(b) Administrator: The person or entity having the responsibility and duty to administering and ensuring compliance with SWP3 and CSWMP. The Administrator shall be appointed by the Village of South Amherst and Lorain County Storm Water District (LCSWD).
(c) Best Management Practices: (BMP's) schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of Waters of the United States. BMP's also include treatment requirements, operating procedures, and practices to control plant and/or construction site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
(d) Buffer: A designated transition area around water resources or wetlands that is left in a natural, usually vegetated, state to protect the water resources or wetlands from runoff pollution. Construction activities in this area are restricted or prohibited.
(e) Construction General Permit: The most recent General National Pollutant Discharge Elimination System (NPDES) permit for authorization of storm water discharges associated with construction activities issued by Ohio EPA (Ohio EPA Permit #OHC000005 and its successors).
(f) County: Lorain County
(g) Critical Storm: A storm which is calculated by means of the percentage increase in volume runoff by a proposed land-disturbing activity or development area. The critical storm is used to calculate the maximum allowable storm water discharge rate from a site.
(h) Cut: an excavation. The difference between a point on the original ground and a designated point of lower elevation on the final grade.
(i) Detention basin: An impoundment area created by constructing an embankment, excavating a pit, or both, for the purpose of temporarily storing storm water.
(j) Detention facility: A detention basin or alternate structure designed to temporarily store storm water runoff and gradually release the stored water at a controlled rate.
(k) Development: A group of dwellings, industrial or commercial buildings, usually constructed as part of a single project.
(l) Development Area: any area upon which land-disturbing activities are planned or underway for a development.
(m) Land-Disturbing Activity: any grading, excavation, filling, or other alteration of the earth's surface where natural or man-made ground cover is destroyed.
(n) LCSWD: Lorain County Storm Water District
(o) Federal Emergency Management Agency (FEMA): the agency with the responsibility for administering the National Flood Insurance Program.
(p) Fill: any act by which earth, sand, gravel, rock or any other material is placed, pushed, dumped, pulled, transported or moved to a new location above the natural surface of the ground or on top of the stripped surface. The difference in elevation between a point on the original ground and a designated point of higher elevation on the final grade.
(q) Grubbing and clearing: machine clearing of vegetation. Usually performed as the first step in the development of land.
(r) Non-structural controls: storm water runoff control and treatment techniques that use natural measures to control runoff and/or reduce pollution levels. Examples include minimizing impervious area, buffer strips along streams, and preserving natural vegetation.
(s) NPDES: National Pollutant Discharge Elimination System.
(t) Parcel: any legally described piece of land created by a partition, subdivision, deed or other instrument recorded with the appropriate entity or agency.
(u) Peak Rate of Runoff - the maximum rate of runoff for any storm of a given frequency and duration.
(v) Pre-Development Conditions: site conditions as they existed as of June 30, 2007.
(w) Riparian: Relating to the banks of a natural course of water.
(x) SABPA: South Amherst Board of Public Affairs
(y) Sediment Basin: a barrier, dam or other facility built to reduce the velocity of water in order to settle and retain sediment.
(z) Silviculture: A branch of forestry dealing with the development and care of forests.
(aa) Stop-Work order: An order issued which requires that all work on the site must cease except work associated with bringing the site into compliance with the approved SWM Plan or Site Development Plan.
(bb) Comprehensive Storm Water Management Plan (CSWMP): The written document which meets the requirements of this Ordinance, sets forth the plans and practices to be used to minimize storm water runoff from a site, and to safely convey or temporarily store and release post-development storm water runoff at an allowable rate which minimizes flooding and erosion.
(cc) Storm Water Pollution Prevention Plan (SWPPP): The document required by the Ohio EPA for compliance with its NPDES Construction Activity General Permit. The written document or set of plans which meet the requirements of this Ordinance that provide information regarding the location of the area proposed for development, the site in relation to its general surroundings, and the existing characteristics of the site, including limits of land-disturbing activities.
(dd) Storm Frequency: the average period of time in years within which a storm of a given duration and intensity can be expected to be equaled or exceeded.
(ee) Structural controls: any man-made facility, structure, or device that is constructed to provide temporary storage and/or treatment of storm water runoff. Examples include retention and detention basins, rock check dams, swales, and constructed wetlands.
(ff) Swale: a low-lying length of vegetated land with a "V" - shaped cross-section which collects and carries surface water.
(gg) Temporary vegetation: short-term vegetated cover such as oats, rye, or wheat, used to stabilize the soil surface until final grading and installation of permanent vegetation.
(hh) Watercourse: any natural or artificial surface waterway (including, but not limited to, streams, rivers, creeks, ditches, channels, canals, waterways, gullies, ravines, or washes) in which waters flow in a definite direction or course either continuously or intermittently and including any area adjacent thereto which is subject to inundation by overflow of flood water.
