Lot, <br />Usable also excludes all areas within lots having slopes greater than <br />20%, all bodies of water including, but not limited to, ponds, lakes <br />and reservoirs as well as the area within wildlife corridors as defined <br />in the Land Use Element of the Orange County Comprehensive Plan. <br />For calculation of Lot, Usable the maximum width of a wildlife <br />corridor is 150 feet or the width of the stream buffer, whichever is <br />greater. <br />Section 2: Amend Section 6.23.7a and Article 22 DEFINITIONS of Stream Buffer to <br />clarify that the stream buffer is not to be included within the floodplain. <br />Stream Buffer -- a stream buffer is an area of land adjacent to perennial <br />and intermittent streams or FEMA identified floodplains, whichever is <br />greater, which, except as permitted in Article 6.23:7 of this Ordinance, <br />must remain undisturbed in its natural state. Perennial streams are shown <br />as solid blue lines and intermittent streams as broken lines on the USGS <br />Quadrangle maps. The stream buffer shall extend around the <br />perimeter of all water bodies including ponds, lakes and reservoirs. <br />Section 3: (page 6-41 -Zoning Ordinance) 6.23.7d. Calculating the Width of Stream <br />Buffer <br />Those streams identified by FEMA as having floodplains shall have <br />stream buffers calculated from the outside edges of the floodplain. <br />1) How to Calculate Slope (See illustration attached) <br />3 <br />a.
