(e) Construction entrance: The permitted points of ingress and egress to development areas regulated under this Chapter.
(f) 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.
(g) Disturbed area: An area of land subject to erosion due to the removal of vegetative cover and/or soil disturbing activities.
(h) Drainage: The removal of excess surface water or groundwater from land by surface or subsurface drains.
(i) Drainage area: The area of land contributing surface water to a specific point.
(j) 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.
(k) Erosion and sediment control: The control of soil, both mineral and organic, to minimize the removal of soil from the land surface and to prevent its transport from a disturbed area by means of wind, water, ice, gravity, or any combination of those forces.
(l) Final stabilization: All soil disturbing activities at the site have been completed and a uniform perennial vegetative cover with a density of at least 70% coverage for the area has been established or equivalent stabilization measures, such as the use of mulches or geotextiles, have been employed.
(m) Landscape architect: A Professional Landscape Architect registered in the State of Ohio.
(n) Larger common plan of development or sale: A contiguous area where multiple separate and distinct construction activities may be taking place at different times on different schedules under one plan.
(o) Maximum extent practicable: The level of pollutant reduction that site owners of small municipal separate storm sewer systems regulated under 40 C.F.R. Parts 9, 122, 123, and 124, referred to as the National Pollutant Discharge Elimination System (NPDES) Storm Water Phase II, must meet.
(p) 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.
(q) Ohio EPA NPDES general construction permit: A permit issued by the Ohio Environmental Protection Agency to an applicant for the discharge of storm water from sites where construction activity is being conducted with discharges to subsequent receiving waters. (Permit Number OHC000002 as amended)
(r) Parcel: A tract of land occupied or intended to be occupied by a use, building or group of buildings and their accessory uses and buildings as a unit, together with such open spaces and driveways as are provided and required. A parcel may contain more than one contiguous lot individually identified by a “Permanent Parcel Number” assigned by the Summit County Fiscal Office.
(s) Person: 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.
(t) Phasing: Clearing a parcel of land in distinct sections, with the stabilization of each section before the clearing of the next.
(u) Professional Engineer/Surveyor: A professional registered in the State of Ohio by the appropriate board.
(v) Qualified individual: Professional Engineers, Professional Surveyors, and Landscape Architects registered in the State of Ohio or a Certified Professional in Erosion and Sediment Control as recognized by CPESC Inc.
(w) Rainwater and Land Development Manual (RWLD): Issued by Ohio Department of Natural Resources. The RWLD Manual contains Ohio’s minimum technical standards for post construction storm water quality and erosion and sediment control standards. The most current edition of these standards shall be applicable with this Chapter.
(x) Runoff: The portion of rainfall, melted snow, or irrigation water that flows across the ground surface and is eventually conveyed to water resources or wetlands.
(y) Sediment: The soils or other surface materials that are transported or deposited by the action of wind, water, ice, gravity, or any combination of those forces, as a product of erosion.
(z) Sedimentation: The deposition or settling of sediment.
(aa) Setback: A designated transition area around water resources or wetlands that is left in a natural, usually vegetated, state so as to protect the water resources or wetlands from runoff pollution. Soil disturbing activities in this area are restricted by this Chapter.
(bb) Soil disturbing activity: Clearing, grubbing, 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, erosion and sediment pollution.
(cc) Soil erodibility: The susceptibility of soil to erosion and the amount and rate of runoff, as measured under the standard unit plot condition. Soil erodibility factors are available in the Summit County Soil Survey.
(dd) Summit County Storm Water Management Manual: Summit County’s storm water management requirements developed and updated by the County Engineer.
(ee) Summit Soil and Water Conservation District: A subdivision of the State of Ohio organized under Chapter 1515 of the Ohio Revised Code referring to either the Soil and Water Conservation District Board or its designated employee(s). Hereafter referred to as Summit SWCD.
(ff) Stabilization: The use of BMPs, such as seeding and mulching, that reduce or prevent soil erosion by water, wind, ice, gravity, or a combination of those forces.
(gg) Stream: A surface water course with a well defined bed and bank, either natural or artificial, which confines and conducts continuous or periodical flowing water in such as way that terrestrial vegetation cannot establish roots within the channel. (ORC 6105.01)
(hh) Storm Water Pollution Prevention Plan (SWP3 or SWPPP): The written document that sets forth the plans and practices to be used to meet the requirements of this Chapter.
(ii) Storm Water Pollution Prevention Plan Checklist: Details the minimum requirements of a SWP3 in Summit County, available at the Summit SWCD office.
(jj) Unstable soils: A portion of land that is identified by the City Engineer, Building Department and/or the Summit SWCD as prone to slipping, sloughing, or landslides, or is identified by the U.S. Department of Agriculture Natural Resource Conservation Service methodology as having a low soil strength.
(kk) Water resource: Any public or private body of water including lakes and ponds, as well as any brook, creek, river, or stream having banks, a defined bed, and a definite direction of low, either continuously or intermittently flowing.
(ll) 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 (33 CFR part 328, as amended).
(mm) Wetland professional: An individual with training and experience in wetland delineation acceptable to the Army Corp of Engineers.
