79 <br /> Nest 54 Biological Inventory Report Orange County,N.C. <br /> Two wetlands were identified within the PSA (Table 8). The locations of these wetlands <br /> are shown on Figure 3. All wetlands within the PSA are located within the Cape Fear River <br /> Basin(USGS HUC 03020002). USACE wetland determination forms and North Carolina <br /> Wetland Assessment Method(NCWAM) forms are included in a separate PJD Package. <br /> Table 8.

River Basin Buffer Rules <br /> Streamside riparian zones within the PSA are protected under provisions of the Jordan <br /> Lake Riparian Buffer Rules, administered by NCDWR. Per the Jordan Lake Riparian <br /> Buffer Rules, streams depicted on the most recent published manuscript of the Orange <br /> County Soil Survey (prepared by the Natural Resource Conservation Service [MRCS], of <br /> the United States Department of Agriculture [USDA]), or the United States Geologic <br /> Survey's (USGS) National Map shall require a total of 50 perpendicular feet of riparian <br /> buffer from the stream top-of-bank. This 50'riparian buffer has two zones. Zone 1 consists <br /> of the first 30 undisturbed perpendicular feet from the stream top-of-bank. Zone 2 consists <br /> of the outer 20 perpendicular feet, starting from the outer edge of Zone 1. Limited <br /> disturbance is allowed in Zone 2. Specific disturbance activities and uses which are <br /> allowed in Zone 2 can be found in Items (9) and(11) of the Jordan Lake Buffer Rules. <br /> In addition to the 50' buffer requirements of the Jordan Lake riparian buffer rules, the <br /> Orange County Unified Development Ordinance(UDO)requires additional buffers,which <br /> are determined by slope severity within 250 perpendicular feet from the stream top-of- <br /> bank. Section 6.13 of the UDO explains how to calculate the width of stream buffers. <br /> Slope values within the PSA are less than 7.5%. As a result, an additional 15' of buffer <br /> shall be applied to Zone 2 of the pre-existing 50' Jordan Lake buffers. If wetlands,ponds, <br /> lakes, or other surface waters partially occur within the 65' buffer of streams within the <br /> PSA, the buffer shall extend around the perimeters of those water features, thereby <br /> protecting them as well. <br /> 15 April 2023 <br />
