   BUFFER.
      (1)   An area of natural or planted vegetation through which storm water runoff flows in a diffuse manner so that the runoff does not become channelized and which provides for infiltration of the runoff and filtering of pollutants.
      (2)   The BUFFER is measured landward from the normal pool elevation of impounded structures and from the bank of each side of streams or rivers.
   BUILDING. Any structure having a roof supported by columns or by walls, and intended for shelter, housing or enclosure of persons, animals or property. The connection of 2 buildings by means of an open porch, breezeway, passageway, carport or other open structure, with or without a roof, shall not be deemed to make them 1 BUILDING.
   BUILT-UPON AREA. Built-upon areas shall include that portion of a developed project that is covered by impervious or partially impervious cover including buildings, pavement, gravel roads, recreation facilities (e.g. tennis courts) and the like. (Note: Wooden slatted decks and the water area of a swimming pool are considered pervious.)
   CLUSTER DEVELOPMENT. The grouping of buildings in order to conserve land resources and provide for innovation in the design of the project. This term includes non-residential development as well as single-family residential subdivisions and multi-family developments that do not involve the subdivision of land.
   COMPOSTING FACILITY. A facility in which only stumps, limbs, leaves, grass and untreated wood collected from land clearing or landscaping operations is deposited.

      (1)   The area adjacent to a water supply intake or reservoir where risk associated with pollution is greater than from the remaining portions of the watershed.
      (2)   The CRITICAL AREA is defined as extending either 1/2 mile from the normal pool elevation of the reservoir in which the intake is located or to the ridge line of the watershed (whichever comes first); or 1/2 mile upstream from the intake located directly in the stream or river (run-of-the-river), or the ridge line of the watershed (whichever comes first).
      (3)   Since WS-I watersheds are essentially undeveloped, establishment of a CRITICAL AREA is not required.
      (4)   Local governments may extend the CRITICAL AREA as needed.
      (5)   Major landmarks such as highways or property lines may be used to delineate the outer boundary of the CRITICAL AREA if these landmarks are immediately adjacent to the appropriate outer boundary of 1/2 mile.
   CUSTOMARY HOME OCCUPATIONS. Any use conducted entirely within a dwelling and carried on by the occupants thereof, which use is clearly incidental and secondary to the use of the dwelling for residential purposes and does not change the character thereof. Provided further that no mechanical equipment is installed or used except as is normally used for domestic or professional purposes, and that not over 25% of the total floor space of any structure is used for the occupation. No home occupation shall be conducted in any accessory building except for the storage and service of a vehicle that is driven off site, such as a service repair truck, delivery truck and the like.
   DEVELOPMENT. Any land disturbing activity, which adds to or changes the amount of impervious or partially impervious cover on a land area or which otherwise decreases the infiltration of precipitation into the soil.

   EXISTING LOT (LOT OF RECORD). A lot which is part of a subdivision, a plat of which has been recorded in the office of the Register of Deeds prior to the adoption of this chapter, or a lot described by metes and bounds, the description of which has been so recorded prior to the adoption of this chapter.
