For the purpose of this Chapter, the definitions used in Section 941.02 of the County of Summit Codified Ordinances apply and the following terms shall have the meaning herein indicated:
(a) AS-BUILT SURVEY: A survey shown on a plan or drawing prepared by a Registered Surveyor indicating the actual dimensions, elevations, ground contours, ground cover vegetation, and locations of any structures, pavements, underground utilities, swales, detention facilities, and sewage treatment facilities after construction is completed.
(b) CLEAN WATER ACT: The Federal Water Pollution Control Act or the Federal Water Pollution Control Act Amendments of 1972, and thereafter.
(c) COMPREHENSIVE STORM WATER MANAGEMENT PLAN: The written document that includes the Improvement Plans and the Storm Water Pollution Prevention Plan, setting forth the practices to minimize storm water runoff from a development area.
(d) COUNTY DRAINAGE ENGINEER: The County Engineer or an entity designated by the Summit County Council to serve as the County Drainage Engineer, if that designation is not the County Engineer.
(e) CRITICAL STORM: A storm event calculated to create the maximum allowable storm water discharge rate from a developed site.
(f) DEVELOPMENT DRAINAGE AREA: A combination of each hydraulically unique watershed with individual outlet points on the development area.
(g) EXTENDED CONVEYANCE: A water management practice that replaces and/or enhances traditional open or closed storm drainage conduits by retarding flow, promoting percolation of runoff into the soil, and filtering pollutants during a storm event.
(h) EXTENDED DETENTION: A water management practice that replaces and/or enhances traditional detention facilities by releasing the runoff collected during a storm event over at least twenty-four (24) to forty-eight (48) hours, retarding flow and allowing pollutants to settle within the facility.
(i) FACILITY: An interconnected collection of structural, and nonstructural, storm water runoff controls and treatment techniques, or devices, to control runoff and/or reduce pollution levels.
(j) GRADING: The process in which the topography of the land is altered.
(k) HYDROLOGIC UNIT CODE: A cataloging system developed by the United States Geological Survey, and the Natural Resource Conservation Service, to identify watersheds in the United States.
(l) IMPERVIOUS COVER: Any surface that cannot effectively absorb, or be infiltrated by, water. This may include roads, streets, driveways, parking lots, rooftops, sidewalks, compacted ground surfaces, and other areas not covered by vegetation.
(m) INFILTRATION: A storm water management practice that does not discharge to a storm water resource during the storm event, requiring collected runoff to either infiltrate into the groundwater and/or be consumed by evapotranspiration, thereby retaining storm water pollutants within the facility.
(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) NONSTRUCTURAL STORM WATER MANAGEMENT PRACTICE: Storm water runoff control and treatment techniques that use natural practices to control runoff and/or reduce pollution levels.
(p) POST-DEVELOPMENT: The conditions that exist after soil disturbing activity that changes the topography, vegetation, land use, or water runoff.
(q) PRE-CONSTRUCTION MEETING: Meeting prior to construction between all parties associated with the construction of the project including government agencies, contractors and owners to review agency requirements and plans as approved and submitted.
(r) PRE-DEVELOPMENT: The conditions that exist prior to soil disturbing activity that changes the topography, vegetation, land use, or water runoff.
(s) REDEVELOPMENT: A construction project on previously developed land where impervious cover has been created, and where new development will not increase the runoff coefficient.
(t) RIPARIAN AREA: Land adjacent to any brook, creek, river, or stream having a defined bed and bank that, if appropriately sized, helps to stabilize stream banks, limit erosion, reduce flood size flows, and/or filter and settle out runoff pollutants, or performs other functions consistent with the purposes of this Chapter.
(u) RIPARIAN SETBACK: The real property adjacent to a water resource on which soil disturbing activities are limited, all as defined by Summit County Codified Ordinances, Chapter 937 – Riparian Setbacks.
(v) STABILIZATION: The use of Best Management Practices that reduce or prevent soil erosion from water runoff, trench dewatering, wind, ice, gravity, or a combination thereof.
(w) STRUCTURAL STORM WATER MANAGEMENT PRACTICE: Any constructed facility, structure, or device that provides storage, conveyance, and/or treatment of storm water runoff.
(x) WATER QUALITY VOLUME: The volume of runoff from a contributing watershed that must be captured and treated, equivalent to the maximized capture volume as defined by current standards of the American Society of Civil Engineers (ASCE).
(y) WATER RESOURCE CROSSING: Any bridge, box, arch, culvert, truss, or other type of structure intended to convey people, animals, vehicles, or materials from one side of a watercourse to another. This does not include pole mounted aerial electric or telecommunication lines, nor does it include below grade utility lines.
(z) WATERSHED: The total drainage area contributing water runoff to a single point.
