source inputs to receiving waters in order to achieve water quality protection <br /> goals. <br /> D. Buffer-a natural or vegetated area through which stormwater runoff flows in a <br /> diffuse manner so that the runoff does not become channelized and which <br /> provides for infiltration of the runoff and filtering of pollutants. The buffer shall <br /> be measured landward from the normal pool elevation of impounded structures <br /> and from the bank of each side of streams or rivers. <br /> E. Built-upon area-that portion of a development project that is covered by <br /> impervious or partially impervious cover including buildings,pavement, gravel <br /> areas (e.g. roads,parking lots,paths),recreation facilities (e.g. tennis courts) etc.' <br /> (Note: Wooden slatted decks and the water area of a swimming pool are <br /> considered pervious.) <br /> F. Channel-a natural water-carrying trough cut vertically into low areas of the <br /> land surface by erosive action of concentrated flowing water or a ditch or canal <br /> excavated for the flow of water. <br /> G. Cluster Development-the grouping of buildings in order to conserve land <br /> resources and provide for innovation in the design of the project including <br /> minimizing stormwater runoff impacts. This term includes nonresidential <br /> development as well as single-family residential and multi-family developments.' <br /> For the purpose of this Ordinance,planned unit developments and mixed use <br /> development shall be considered cluster development. <br /> H. County- shall mean Orange County. <br /> I. DBH- diameter at breast height of a tree,which is measured at 4.5 feet above! <br /> ground surface level. <br /> I Development-any land-disturbing activity which adds to or changes the <br /> amount of impervious or partially impervious cover on a land area or which <br /> otherwise decreases the infiltration of precipitation into the soil. <br /> K. Discharge-the addition of any man-induced waste effluent either directly or <br /> indirectly to state surface waters. <br /> L. Ditch or canal- a man-made channel other than a modified natural stream <br /> constructed for drainage purposes that is typically dug through inter-stream <br /> divided areas. A ditch or canal may have flows that are perennial, intermittent, orl <br /> ephemeral and may exhibit hydrological and biological characteristics similar to <br /> perennial or intermittent streams. <br /> M. Domestic wastewater discharge-the discharge of sewage,non-process <br /> industrial wastewater, other domestic wastewater or any combination of these <br /> items. Domestic wastewater includes,but is not limited to, liquid waste generated <br /> by domestic water using fixtures and appliances,from any residence,place of <br /> business, or place of public assembly even if it contains no sewage. Examples of <br /> domestic wastewater include once-through non-contact cooling water, seafood <br /> I <br />
