PACE2 s The required stream buffer zone shall not be limited to one calculation but shall be based on calculations made at points where topographical and ground cover conditions change based on an analysis of the site. In addition to the buffer zone resulting from the above calculations, a stream buffer shall include any portion of a floodplain as defined in the Orange County Flood Damage Prevention Ordinance, by special survey by a registered engineer or surveyor or by alluvial soils as designated in the Orange County Soils Survey. 6.25.5.2 Buffer Zones Included As Part Of Minimum Lot Size Stream buffer zones can be used as part of the required lot area or lot size established as part of these development standards. 6.25.5.3 Existing Vegetation in Buffer Zones Existing forested areas and other vegetation in a healthy condition cannot be removed from or disturbed in a stream buffer zone. Diseased and/or dead vegetation may be removed and replaced with vegetation resulting a comparable stormwater runoff velocity and quantity. 6.25.5.4 Permitted Uses Within Buffer Zones Notwithstanding any other provisions of this Article, no impervious surface shall be located in or closed than twenty (20) feet to the nearest edge of a designated buffer zone, except that the Zoning Officer may authorize the crossing of a designated buffer zone and the presence of impervious surface therein by or for: a. A public or private street where the crossing is perpendicular. to the stream and is justified in that: . 1. Without such a crossing, over fifty percent (50%) of the land area would be without access and therefore undevelopable; or - 2. It allows a design that would clearly result in less damage to the watershed than would result if the property were developed without such a crossing. b. Above ground and buried utility lines for the distribution of electricity, gas, telephone, and cable television service where: 1. It is practicably unavoidable if the subject property and adjoining property are to be served or potentially served by a public service, and an alternate design would result in greater damage to the watershed; and 2. The system, as a whole, emphasizes placement outside designated buffer zones; and 3. To the extent practical, the direction of the line crossing is perpendicular to the stream.
