PROJECT DETAIL AND HISTORY I.I. Site Location The site is located northeast and adjacent to the intersection of Weddington Road and North Rocky River Road in Monroe, Union County (Figure 1). The site consists of two parcels. According to the Union County GIS service, the parcels are identified as Parcel Identification Numbers (PIN) 09348013A (21.346 acres) and 09348013B (35.89 acres), and are owned by Harris Teeter Properties, LLC. 1.2. Current Conditions and Regulatory Verification Headwater identified three wetland areas and one intermittent stream within the site boundary (Figure 2). Wetland Area A is located on the northern portion of the site. Wetland Area A is wooded with a prolific herbaceous understory. Wetland Area B is located on the southern portion of the site, abutting Stream A. Wetland Area B is wooded, and Stream A is intermittent. Wetland Area B is seasonally saturated. A stream and/or culverted drainage system connects the wetland areas to downstream Waters of the U.S. Therefore, Wetland Areas A and B are considered jurisdictional wetlands. Wetland C is located on the central portion of the site. A manmade berm separates the southern portion of Wetland A from Wetland C. Manmade berms and/or structures do not limit jurisdictional status of wetland resources. Therefore, Wetland Area C is considered a jurisdictional wetland. Both wetland Area A and Area C are seasonally inundated. Wetland Area B is seasonally saturated. On November 26, 2018, Headwater completed a regulatory visit with Mr. Alan Johnson of DWR. Mr. Johnson agreed, Stream A is an intermittent feature regulated by DWR. On January 15, 2019, Headwater completed a regulatory site visit with Mr. Bryan Roden - Reynolds of the USACE. Wetland C was flagged and GPS'd in the field during the regulatory visit with Mr. Roden -Reynolds. Mr. Roden -Reynolds agreed with the wetland and stream locations. The signed JD (SAW-2006-40743) was received on January 18, 2019. Fill mounds have been placed along the southern portion of Wetland Area C. The fill mounds are numerous and range from three to five feet tall. On October 9, 2019, Headwater GPS'd and mapped the extent of fill mounds. The fill mounds encompass 0.38 acre. Mature trees are growing throughout the area of fill mounds. The diameter at breast height ranges from 10" to 36". Based on dbh of the various tree species, the fill mounds appear to have been placed at the site 25 to 50 years ago. Evidence of land disturbance in the vicinity of the fill mounds is visible on the archive soil map, circa 1996 (Figure 3). The canopy trees were identified, geo-located, and included on Figure 4. 1.3. Purpose/Proposed Plans The proposed project includes develop of a 184-lot residential subdivision consisting of single-family homes. There will be two access roads to the proposed subdivision. The access roads will extend north from Weddington Road and east from North Rocky River Road. Headwater Project #201816 October 29, 2019 1.4. Impacts to Waters of the U.S. Impacts to Wetland A on the northern portion of the site are necessary to build a required stormwater pond (BMP) for the proposed subdivision. The proposed 0.44-acre wetland impact utilizes the lowest suitable location at the site. Surface runoff naturally flows into the BMP. Placement of the BMP on other areas of the site are not feasible because of higher elevations which would not allow for surface runoff to be captured by the BMP. In order to avoid impacts to the stream and associated buffer, placement of the BMP on the southern portion of the site was not considered. In lieu of financial payment to the North Carolina Division of Mitigation Services, Headwater recommend restoring the wetland area impacted from the placement of relic fill material. Wetland Impacts 0.44 acre Proposed Restoration 0.38 acre Net wetland impacts 0.06 acre After restoration activity is complete, wetland impacts will be less than 1/10 acre. Therefore, financial contribution to the North Carolina Division of Mitigation Services is not proposed. II. RESTORATION PLAN 11.1. Methodology a) Time Frame The restoration efforts shall be performed in conjunction with site clearing and grading. Detailed site plans are included with the permit application. Equipment to be used will include earth moving equipment, such as, an excavator and bulldozer. b) Fill Mound Removal Metal grade stakes will be placed at six representative fill mound locations. The depth of fill will be marked with red spray paint and the natural grade depth will be marked with green spray paint. The red and Representative till mound Range 3' to ' — — _ — — — Top of fill. Area to be removed .7 y Top of natural grade & l elevation of acipcent wetland green markings will provide the equipment operator a visual queue to the natural grade elevation. The fill material be removed and placed in upland portions of the site. The fill material will be incorporated to the grading plan associated with the proposed project. Japanese stilt grass (Microstegium vimineum) and Chinese privet (Ligustrum sinense) and dominate the understory throughout the fill mound area. These species will be removed. Mature trees will not be removed during fill mound removal. K Headwater Project #201816 October 29, 2019 c) Planting Schedule After fill mound removal. Headwater shall oversee the planting of assorted herbaceous and sapling species. Due to the mature canopy, the recommended species are all shade tolerant. We recommend planting water oak (Quercus nigra) and ironwood (Carpinus caroliniana). Herbaceous species include uptight sedge (Carex stricta), soft rush (Juncus effusus), royal fern (Osmunda regalis), and common three square (Schoenoplectus pungens). A planting diagram is included on Figure 5. Osmocote fertilizer will be used at each planting location. The recommended planting list includes native wetland species found throughout the piedmont of North Carolina. 11.2. Monitoring Illustrative signage will place at three locations, around the perimeter of the restored wetlands. Additionally, silt fencing shall be placed around the perimeter of the existing and restored wetlands during the duration of construction. Upon completion of restoration activity, photo -documentation will be provided to USACE. Annual monitoring of Wetland C for a period of three (3) years after the project's completion will document the success and progress of the restoration efforts. 3 1: 1V w �= • �� BM 64 1. f O a Tr 1 655 J 640 GF Legend Site boundary?.

Bearskin Creek is classified as Class C Waters. Riparian Y buffers are not implemented by the DWR o along streams in this river basin. X z 2. According to Monroe Code of Ordinances, Code §158.06, the width of the buffer zone begins and is measured landward from the nearest edge of the disturbed area and/or five feet from the edge of the top of the bank of streams or rivers to the nearest edge of the disturbed area. k I Stream A 2' x 950' Wetl and A Acres 0.78 Wetland B Acres 0.27 Wetland C Acres 0.64 Wetland Acres 1.69 Upland Acres 53.00 Site Acres 54.69 Weddington Rd ra f .c Feet 0 200 400 800 Headwater Jor ENVIRONMENTAL INC.
