§ 153.023 DEFINITIONS.
   For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   100-YEAR FLOODPLAIN. Any land susceptible to being inundated by water from a base flood, which is the flood that has a 1% or greater chance of being equaled or exceeded in any given year. For the purposes of these regulations, the 100-YEAR FLOODPLAIN shall be defined by FEMA and subject to review and approval per Ordinance 2002-02.
   BEST MANAGEMENT PRACTICES (BMPs). Conservation practices or protection measures which reduce impacts from a particular land use. BEST MANAGEMENT PRACTICES for construction are outlined in Rainwater and Land Development, Ohio’s Standard for Storm Water Management, Land Development, and Urban Stream Protection prepared by the Ohio Department of Natural Resources.
   DAMAGED OR DISEASED TREES. Trees that have split trunk, broken tops, heart rot, insect or fungus problems that will lead to imminent death, undercut root systems that put the tree in imminent danger of falling, lean as a result of root failure that puts the tree in imminent danger of falling, or any other condition that puts the tree in imminent danger of being uprooted or falling into or along a stream or onto a structure.
   DEFINED CHANNEL. A natural or human-made depression in the terrain which is maintained and altered by the water and sediment it carries.
   FEDERAL EMERGENCY MANAGEMENT AGENCY (FEMA). The agency with overall responsibility for administering the national flood insurance program.
   FINAL PLAT. A final tracing of all or a phase of a subdivision and its complete survey information.
   IMPERVIOUS COVER. Any surface that cannot effectively absorb or infiltrate water. This may include roads, streets, parking lots, rooftops, sidewalks and other areas not covered by vegetation.
   NATURAL SUCCESSION. A gradual and continuous replacement of one kind of plant and animal group by a more complex group. The plants and animals present in the initial group modify the environment through their life activities, thereby making it unfavorable for themselves. They are gradually replaced by a different group of plants and animals better adapted to the new environment.
   NOXIOUS WEED. Any plant defined as PROHIBITED NOXIOUS WEEDS in O.A.C. 901:5-37-01 and any of the following: Goldenrod, Poison Hemlock, Poison Ivy, Poison Oak, Ragweed, Stinging Nettle and other plants capable of causing skin reactions upon contact or producing severe allergic respiratory reactions.
   OHIO RAPID ASSESSMENT METHOD. A multi-parameter qualitative index established by the Ohio Environmental Protection Agency to evaluate wetland quality and function.
   ORDINARY HIGH WATER MARK. The point of the bank or shore to which the presence and action of surface water is so continuous as to leave a district marked by erosion, destruction or prevention of woody terrestrial vegetation, predominance of aquatic vegetation or other easily recognized characteristic. The ORDINARY HIGH WATER MARK defines the channel of a stream.
   POLLUTION. Any contamination or alteration of the physical, chemical or biological properties of any waters that will render the waters harmful or detrimental to: public health, safety or welfare; domestic, commercial, industrial, agricultural, recreational or other legitimate beneficial uses; or livestock or wildlife, including birds, fish or other aquatic life.
      (1)   POINT SOURCE POLLUTION. Traceable to a discrete point or pipe.
      (2)   NONPOINT SOURCE POLLUTION. Generated by various land use activities, rather than from an identifiable or discrete source, and is conveyed to waterways through natural processes, such as rainfall, storm runoff or ground water seepage rather than direct discharge.
   PRELIMINARY PLAN. A drawing of a major subdivision for the purpose of study and which, if approved, permits proceeding with the preparation of the final plat.
   RIPARIAN AREA. A transitional area between flowing water and terrestrial ecosystems which provides a continuous exchange of nutrients and woody debris between land and water. This area is at least periodically influenced by flooding. RIPARIAN AREAS, if appropriately sized and managed, help to stabilize banks, limit erosion, reduce flood size flows and/or filter and settle out runoff pollutants, or perform other functions consistent with the purposes of these regulations.
   RIPARIAN SETBACK. The area set back from each bank of a stream to protect the riparian area and stream from impacts of development, and streamside residents from impacts of flooding and land loss through erosion. RIPARIAN SETBACKS are those lands within the city that fall within the area defined by the criteria set forth in these regulations.
   SOIL AND WATER CONSERVATION DISTRICT (SWCD). An entity organized under R.C. § 940.06 referring to either the Soil and Water Conservation District Board or its designated employees, hereinafter referred to as the County SWCD.
   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 which may result in, or contribute to, erosion and sediment pollution.
   STORM WATER POLLUTION PREVENTION PLAN (SWPPP). The plan which describes all the elements of the storm water strategy implemented during and after construction. The plan addresses erosion control and storm water quality.
   STORM WATER QUALITY TREATMENT. The removal of pollutants from urban runoff and improvement of water quality, accomplished largely by disposition and utilizing the benefits of natural processes.
   STREAM. A surface watercourse with a well-defined bed and bank, either natural or artificial, which confines and conducts continuous or periodical flowing water in such a way that terrestrial vegetation cannot establish roots within the channel.
   VARIANCE. A modification of the enforcement of this chapter which will not be contrary to the public interest and where, due to conditions peculiar to this property and not the result of the action of the applicant, a literal enforcement of this chapter would result in undue hardship to the applicant.
   WATERCOURSE. A natural or artificial waterway, such as a stream or river, with a defined bed and channel and a definite direction of course that is contained within, flows through or borders the community.
   WATERSHED. An area of land that drains into a particular watercourse, usually defined by topography.
   WETLANDS. 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.
