The slope shall be calculated by measuring a distance 250 feet frcm the cen- ter of the stream, determining the average rise in elevation and multi- plying that value by four. This value shall be added to the minimum buffer of 50 feet to determine total width of buffer area reauired. The maximum buffer in any case shall not exceed 150,feet. The flood plain is'defined in the Orange County Flood uamage Prevention Ordinance, by special survey by registered engineers or surveyors, by the alluvial soil as designated in the Orange County soil survey, or through a site analysis by the Orange County Planning Staff.
