The Site contains (seven) unnamed headwater tributaries that drain to Muddy Creek (Index # 17- 9-(1)), approximately 1.0 mile east of the Site. The 2014 NC Water Quality Assessment for 305(b) waters lists this portion of Muddy Creek as a WS -IV water with two 4t categories. Unnamed tributaries take on the classification of the nearest named stream; therefore, site tributaries are also classified as WS -IV with two 4t categories (Fecal coliform and fish tissue mercury). The Site is comprised of two parcels, one owned by Fran Alicia White (PIN 7727495773) and one owned by Gary Reece White and Patricia H. White (PIN 7727596383). The Site produces 458,128 Buffer Mitigation Units (BMU) through restoration and enhancement of 495,865 square feet of riparian buffers along an unnamed tributary to Muddy Creek (UTMC), UT 1, UT 2 and UT 5 (UT 2A, UT 3 and UT 4 are also included within the easement area but no buffer credits are generated for enhancement of the buffer adjacent to these tributaries because those credits are allocated to UT 2 and UTMC).

The team, including engineers and biologists, walked the entire site making visual assessments, taking notes on the existing condition of streams and riparian buffers and determining the potential for mitigation. If additional data is needed it will be collected during the design phase. An aerial photograph of the Site is provided on Figure 1. Channel Stability mapping and statistics are provided on Figure 2. A United States Geological Survey (USGS) quadrangle map of the Site is provided on Figure 3. FN White Buffer Mitigation Site RFP# 16-007703: Cataloging Unit 03030003 of the Cape Fear River Basin 1.1.1 Channel and Floodplain Characteristics Biological Impairment The majority of streams on the Site have various physical impairments that include: • Significant fine sediment and nutrient loading from runoff from cattle pasture. • Hoof shear of channel banks and bed form from cattle access and wading. • Continual maintenance of riparian buffers and denudation of deep rooted vegetation from those buffers. • Fecal loading into the channels from unabated access of cattle. • Agricultural machinery access. These physical impairments appear to contribute to significant detrimental effects on water quality and biological integrity of the Site. Effects of physical impairment appear to include: • Silting of habitat for fish species and other macrobenthos in the stream channels, • Loss of essential bed form features, • Probability of increased loading of nutrients and pathogens to all stream systems on-site due to maintenance of fields within riparian areas and access of cattle to stream channels, • Denudation of riparian vegetation reduces the ability of the Site to attenuate floodwaters and uptake and store nutrients and other pollutant inputs, • Denudation of riparian vegetation substantially reduces potential woody debris inputs to the channel that are vital for aquatic propagation and cover habitat, and Denudation of riparian vegetation reduces semi -aquatic and terrestrial habitat corridors through the Site. Significant fecal and nutrient loads are entering UTMC and its tributaries as a result of direct cattle access to streams and overland sheetflow from adjacent pastures. Evidence of this includes visual observation of cattle in the stream channel during site visits and fecal matter along stream banks and within the stream channel. Table 2.

Woody vegetation is limited to a one -tree strip along the top of bank of Site streams except for a mature canopy along UT 3, UT 4 and the left floodplain of UT 5. The vegetation along UTMC, UT 1 and UT 2 consists mostly of species such as black willow (Salix nigra), sweetgum (Liquidambar styraciflua) and Chinese privet (Ligustrum sinense). The half -acre of mature canopy along UT 3, UT 4 and the left floodplain of UT 5 consists mostly of sweetgum, willow oak (Quercus phellos), red maple (Acer rubrum) and green ash (Fraxinus pennsylvanica). E 03 White Buffer Mitigation Site RFP# 16-007703: Cataloging Unit 03030003 of the Cape Fear River Basin Herbaceous species on the Site consists of fescue (Fescuta spp.), Japanese stiltgrass (Microstegium vimineum) and sedges (Carex spp). 1.1.3 Soils A soil series map including the project boundary was generated from the USDA-NCSS online SoilWeb Network Link and is depicted in Figure 4. The majority of soils within the Site are mapped as Helena sandy loam, 6 to 10 percent slopes. These soils are moderately well drained with slow permeability, and moderate to rapid runoff. Parent material is a residuum weathered from a mixture of felsic, intermediate or mafic igneous or high-grade metamorphic rocks. 1.1.4 Jurisdictional Streams Seven unnamed tributaries to Muddy Creek are located within the proposed conservation easement. A NCDWQ Stream Identification Form (NCDENR, 2010a) was completed for each UT. UTMC, UT 1 and UT 4 are considered perennial and scored above 28.5 for their entire presence within the project boundary. UT 2 is considered perennial for a portion of its presence with the project boundary with a score of 30.5. Above the perennial reach and to the extent of the proposed conservation easement, UT 2 is considered intermittent and scored 22. UT 3 and UT 5 scored 28 and are considered intermittent tributaries. 2.1 Current Ownership and Long Term Protection Fran Alicia White (PIN 7727495773) and Gary Reece White and Patricia H. White (PIN 7727596383) own lands that comprise the Site. Long term protection of the property is proposed through a conservation easement. The conservation easement is proposed to be transferred to the State of North Carolina. Parcel boundaries showing the two properties are depicted in Figure 1. 3.1 Land Use Changes Historical aerial imagery shows that land within the property boundary has been consistently farmed for cattle from 1999 to Present. Between 1993 and 1999 the field immediately south of UT to Muddy Creek was converted from row cropping to cattle farming. It is assumed that the majority of land within the property boundary was farmed for cattle between 1990 and 1993. 3 03 LEGEND Proposed Easement s `' ■ Gary & Patricia Parcel White Parcel Boundary Al ~....
