(e) DEVELOPMENT AREA: A parcel or contiguous parcels owned by one person or persons, or operated as one development unit, and used or being developed for commercial, industrial, residential, institutional, or other construction or alteration that changes runoff characteristics.
(f) EROSION: The process by which the land surface is worn away by the action of wind, water, ice, gravity, or any combination of those forces.
(g) LARGER COMMON PLAN OF DEVELOPMENT: A contiguous area where multiple separate and distinct construction activities may be taking place at different times on different schedules under one plan.
(h) MAXIMUM EXTENT PRACTICABLE: The level of pollutant reduction that operators of small municipal separate storm sewer systems regulated under 40 C.F.R. Parts 9, 122, 123, and 124, referred to as NPDES Stormwater Phase II, must meet.
(i) NPDES: National Pollutant Discharge Elimination System. A regulatory program in the Federal Clean Water Act that prohibits the discharge of pollutants into surface waters of the United States without a permit.
(j) NONSTRUCTURAL STORMWATER MANAGEMENT PRACTICE: Stormwater runoff control and treatment techniques that use natural practices to control runoff and/or reduce pollution levels.
(k) REDEVELOPMENT: A change to an existing site, including but not limited to the demolition, building or expansion of a structure, filling, grading, paving or excavating.
(l) RUNOFF: The portion of rainfall, melted snow, or irrigation water that flows across the ground surface and is eventually returned to water resources.
(m) SEDIMENT: The soils or other surface materials that can be transported or deposited by the action of wind, water, ice, or gravity as a product of erosion.
(n) SEDIMENTATION: The deposition of sediment in water resources.
(o) SITE OWNER/OPERATOR: Any individual, corporation, firm, trust, commission, board, public or private partnership, joint venture, agency, unincorporated association, municipal corporation, county or state agency, the federal government, other legal entity, or an agent thereof that is responsible for the overall construction site.
(p) SOIL DISTURBING ACTIVITY: Clearing, grading, excavating, filling, or other alteration of the earth’s surface where natural or human made ground cover is destroyed and that may result in, or contribute to, increased stormwater quantity and/or decreased stormwater quality.
(q) STABILIZATION: The use of Best Management Practices that reduce or prevent soil erosion by stormwater runoff, trench dewatering, wind, ice, gravity, or a combination thereof.
(r) STORMWATER MANAGEMENT PLAN (SWM Plan): The written document and plans meeting the requirements of this regulation that sets forth the plans and practices to minimize stormwater runoff from a development area, to safely convey or temporarily store and release post-development runoff at an allowable rate to minimize flooding and stream bank erosion, and to protect or improve stormwater quality and stream channels.
(s) STRUCTURAL STORMWATER MANAGEMENT PRACTICE: Any constructed facility, structure, or device that provides storage, conveyance, and/or treatment of stormwater runoff. Also referred to as a stormwater management facility.
(t) WARRENSVILLE HEIGHTS STORMWATER DESIGN GUIDE: The Design Guide which provides detailed information to be used in the design of the stormwater management plans, stormwater pollution prevention plans, storm sewer and stormwater management facilities. This document is available at the Warrensville Heights Building Department, 19700 Miles Road, Warrensville Heights, Ohio, (216) 587-1230.
(u) WATER RESOURCE: Any public or private body of water; including wetlands; the area within the ordinary high water level of lakes and ponds; as well as the area within the ordinary high water level of any brook, creek, river, or stream having a defined bed and bank (either natural or artificial) which confines and conducts continuous or intermittent flow.
(v) WATERSHED: The total drainage area contributing stormwater runoff to a single point.
(w) WETLAND: Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions, including swamps, marshes, bogs, and similar areas (40 CFR 232, as amended).
