district marked by erosion, destruction or prevention of woody terrestrial vegeta- tion, predominance of aquatic vegetation, or other easily recognized characteris- tic. (gg) OUTFALL means an area where water flows from a structure such as a conduit, storm sewer, improved channel or drain, and the area immediately be- yond the structure which is impacted by the velocity of flow in the structure. (hh) PERSON means any individual, corporation, partnership, joint venture, agency, unincorporated association, municipal corporation, township, county, state agency, the federal government, or any combination thereof. (ii) PROFESSIONAL ENGINEER means a person registered in the State of Ohio as a Professional Engineer. (p) REDEVELOPMENT means the demolition or removal of existing struc- tures or land uses and construction of new ones. (kk) RETENTION BASIN means a storm water management pond that main- tains a permanent pool of water. These storm water management ponds include a properly engineered/designed volume dedicated to the temporary storage and slow release of runoff waters. (11) RIPARIAN AREA means naturally vegetated land adjacent to watercourses which, if appropriately sized, helps to stabilize stream banks, limit erosion, re- duce flood flows, and/or filter and settle out runoff pollutants, or which performs other functions consistent with the purposes of this chapter. (mm) RIPARIAN SETBACK means those lands within the City of Lakewood which are alongside streams where earth disturbing activities will not take place and natural vegetation will not be removed. (mn) RUNOFF means surface water runoff which converges and flows primari- ly through water conveyance features such as swales, gullies, waterways, chan- nels or storm sewers, and which exceeds the maximum specified flow rates of filters or perimeter controls intended to control sheet flow. (oo) SEDIMENT means solid material, both mineral and organic, that is in sus- pension, is being transported, or has been moved from its site of origin by wind, water, gravity or ice, and has come to rest on the earth's surface either on dry land or in a body of water. (pp) SEDIMENT SETTLING POND means a temporary Sediment Pond that releases runoff at a controlled rate. It is designed to slowly release runoff, de- taining it long enough to allow most of the sediment to settle out of the water. The outlet structure is usually a designed pipe riser and barrel. The entire struc- ture is removed after construction. Permanent storm water detention structures can be modified to function as temporary Sediment Basins. (qq) SEDIMENT CONTROL means the limiting of sediment being transported by controlling erosion or detaining sediment -laden water and, allowing the sed- iment to settle out. (rr) SEDIMENT BARRIER means a sediment control device such as a geotex- tile Silt Fence or a grass Filter Strip, usually capable of controlling only small flow rates. (Straw bale barriers are not acceptable.)
