PROJECT DETAIL AND HISTORY Site Location The 32-acre site is located approximately 2,300 feet southeast of the intersection of Erza Moore Road and Bay Road in Teachey, Duplin County, North Carolina (Figure 1A). The site is also situated approximately 2,300 feet north of High School Road. The site is bounded on the east by Interstate 40 and on the south and west by wooded land. There are two points of access to the site. An unpaved access road extends southeast from Bay Road (Access Road 1), and north from Highschool Road (Access Road 2), towards the site. An approximate 100-foot wide overhead electrical easement traverses the site from north to south. Duke Energy maintains the easement and routinely navigates service equipment/vehicles along the easement corridor. The site is comprised of three parcels. Grey Outdoors, LLC owns Parcel 09-3160 (9.35 acres) and Parcel 09-1813-1 (9.61 acres). The Willoughby-Townsend, LLC owns Parcel 09-7000 (36.4 acres). The site includes all of Parcel 09-3160 (Tract 1) and Parcel 09- 1813-1 (Tract 3), and a portion of Parcel 09-7000 (Tract 2). The area west of the electrical easement along Tract 2 is excluded from this assessment. Grey Outdoors, LLC currently has plans to purchase Tract 2 from The Willoughby- Townsend, LLC. Purpose/Proposed Plans Grey Outdoors, LLC intends to develop eight billboards along the eastern site boundary, abutting Interstate 40. Each billboard will be supported with three 3-foot diameter pilings. Temporary and permanent access roads will be utilized to construct the billboards. The billboards shall be situated approximately 500 feet apart. The previous owner of Tract 3 (Corbett Industries, Inc.) has retained timber rights to said parcel of land. It is our understanding The Willoughby-Townsend, LLC shall retain timber rights to Tract 2. Therefore, the future clearing of Tracts 2 and 3 are not associated with the construction of the billboards. Impacts to Waters of the U.S. In June/July 2018, Grey Outdoors, LLC retained a clearing/grading contractor to begin removing vegetation and constructing the lateral access road to the northern most proposed billboard. Construction of the lateral access road began at the southern terminus of Access Road 1. Additionally, a ditch was excavated parallel to the access road. An excavator was utilized to excavate the ditch. The dredged material was sidecast parallel to the ditch to create the lateral access road. Off-site material was not utilized to construct the lateral access road during the construction efforts. A “skid area” was created on the southern portion of Tract 1 and northern portion of Tract 2. The blade of a bulldozer was used to push the upper layer of soil and organic debris to create the skid area. The lateral access road, ditch, dredged material, and skid area all transect jurisdictional wetlands. There are no streams within the site boundary. Headwater Project #201816 August 5, 2019 2 At the time, the wetlands had not been delineated by a consultant, nor verified by U.S. Army Corps of Engineers (USACE). In July 2018, the USACE observed the wetland impacts via Interstate 40. Mr. Tom Charles of the USACE performed a site visit with Mr. Grey Vick in July 2018. Mr. Charles confirmed the construction activity occurred in jurisdictional wetlands. It is our understanding Mr. Vick verbally agreed to restore the wetlands and submit a permit application for the billboard construction project. A violation letter was not issued by the USACE. II. DELINEATION OF WETLANDS, EXCAVATION, AND FILL Methodology In addition to performing a routine wetland delineation, the purpose of the site reconnaissance was to map, locate, and document the extent of wetland impacts. Fill material and areas of excavation were visually observed. A hand auger was used to determine the depth of fill material. In order to identify wetlands, Headwater utilized the “Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region”, issued November 2010. The field reconnaissance involved a general site inspection, wetland observations, and a wetland boundary delineation. The purpose of the site reconnaissance was to verify the published data, inspect the site for the presence of wetlands, and delineate (flag) the wetland/upland boundaries. Headwater utilized the Trimble Geo7x GPS device to locate and map the wetland features. During the field review, examination of wetland characteristics was conducted. Data Points were established and are attached to this report. The Data Points were used to record field data on vegetation, soils, and hydrology. Information collected at each data point includes the following: Characterization of Vegetation Vegetation at each Data Point was characterized as per the appropriate regional supplement to the USACE Wetland Delineation Manual for the following stratum (layer): A. Trees: Woody plants, excluding vines, approximately 20 feet or more in height and three inches or larger in diameter at breast height (DBH). B. Saplings: Woody plants, excluding vines, 20 feet or more in height and less than 3 inches DBH. C. Shrubs: Woody plants approximately 3 to 20 feet in height. D. Herbs: All, non-woody, herbaceous plants less than 3 feet in height. E. Vines: All woody vines, regardless of length or height. Soil Characterization Soil characteristics at each data point were reviewed with the use of a 2-inch diameter Dutch auger. Soil samples were obtained from the ground surface to the depth necessary to identify hydric soil characteristics. The matrix color of each sample was identified and recorded using the standard Munsell Soil Color Chart. Other soil characteristics (i.e.: textures, concretions, structure) of each sample Headwater Project #201816 August 5, 2019 3 were also examined and recorded. Particular emphasis was placed on the identification of (or lack of) certain hydric soil indicators such as low chroma and/or mottled soils. Hydrology Each data point was examined for evidence of surface and subsurface hydrology. Field indicators (i.e.: water stained leaves, oxidized root channels, morphological plant adaptations, etc.) were identified and recorded. Each point was evaluated for primary and secondary indications of wetlands hydrology. Site Reconnaissance Headwater personnel conducted the initial site reconnaissance on August 22, 2018. The initial site reconnaissance was concentrated on Tract 1 and northern portion of Tract 2 (i.e. the area associated with wetland impacts). A second site visit was conducted on February 2, 2019. The purpose of the second site visit was to complete a wetland delineation on the remainder of Tracts 2 and 3. Headwater utilized the Trimble Geo7x to map and locate jurisdictional wetlands and associated impacts (Figures 1B and 1C). The majority of the site is a jurisdictional wetland. All of Tract 3 is comprised of a managed pine flat wetland. Headwater identified four upland “islands” throughout Tracts 1 and 2 (Figure 1B). Although hydrophytic vegetation and saturated soils were observed, the upland islands have non-hydric soils. The soils in the wetland areas have low chroma and low value colors. The wetlands areas are dominated by hydrophytic vegetation and exhibit wetland hydrology indicators. The majority of the wetland is classified as a pine flat wetland. The pine trees become less dominant in areas of lower elevation; these low areas are classified as a hardwood flat wetland. The wetland appears to be seasonally saturated and inundated. Multiple areas of ponding and inundation were present during the August and February site visits. The ponded areas are void of vegetation. The wetland areas along the electrical easement are routinely maintained by Duke Energy and are classified as palustrine emergent wetlands. Refer to Figure 1C for a depiction of wetland types and wetland impacts. A common feature in seasonally inundated hardwood flat wetlands are hummock mounds. A hummock is a small knoll or mound above the grounds’ surface. In the coastal plain of North Carolina hummocks are comprised of mucky peat material, soil, and living plants. These wetland hummocks were observed within the intact wetlands, adjacent to the excavation/skid areas. Data Point 1 (DP-1), DP-2, DP-4, DP-D were collected in a wetland. DP-3, DP-A, DP-B, and DP-C were recorded in an upland. Headwater marked the wetland boundaries with pink surveyor tape. The wetland labeling scheme is included on Table 1. Table 1. Wetland and stream labeling scheme.

Headwater traversed the perimeter boundaries and made several transects across the interior of the site. We used hip waders to traverse the ponded areas. Headwater did not observe additional surface waters or wetlands on the site. In addition to wetland impacts, Figures 7 shows the approximate locations of the wetlands, flags, and data points. Soil Borings In order to determine the depth of fill material placed within the jurisdictional wetlands, Headwater advanced 11 borings throughout Tract 1 and northern portion of Tract 2 (Figure 1D). The depth of fill ranged from eight to 17 inches. Our boring log and photographs are saved in Appendix B. III. RESTORATION PLAN Methodology The restoration efforts shall be performed in conjunction with the construction of the proposed billboards. Detailed site plans are included with the permit application. Equipment to be used will include earth moving equipment, such as, a mini-excavator and bulldozer. After construction of the two northernmost billboards, the temporary access road will be removed, and wetland conditions restored. A permit application will be submitted for the billboards on the southern portion of the site. Fill Areas Grade stakes will be placed at each boring location. 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 green markings will provide the equipment operator a visual queue to the natural grade elevation. The fill material be removed and placed in the adjacent ditch, from which the material originated (Figure 2A). Skid/Excavation Areas The uppermost layer of soil and hummock mounds were mechanically removed from the jurisdictional wetland. In order to restore the jurisdictional wetlands to their previous state, root mats and dense woody material will be selected from the adjacent debris pile and placed in the skid/excavation area. The constructed hummock mounds shall be three to six feet in diameter and placed six to eight feet apart (Figure 2B). Headwater Project #201816 August 5, 2019 5 Organic Debris Piles The remainder of the organic debris piles that are not used for creating hummock mounds shall be removed from the jurisdictional wetlands and placed at an on-site upland staging area. Planting Schedule Headwater has elected to allow the native seedbank to replant the site. The adjacent intact wetlands are comprised of dense thickets of galberry (Ilex coriacea), ink berry (Ilex glabra), Carolina ti-ti (Cyrilla racimaflora), laurel greenbriar (Smilax laurifolia), water tupelo (Nyssa aquatica), red maple (Acer rubrum), and coastal dog hobble (Leucothoe axillaris). Herbaceous species in the electrical easement included Carolina redroot (Lachnathes caroliniana), soft rush (Juncus effusus), switch grass, tufted bulrush (Trichphorum cespitosum), switch cane (Arundinaria tecta), and others. These native species are aggressive by nature and will likely out compete any planted varieties. Monitoring Upon completion of restoration activity, photo-documentation will be provided to USCE. The photo-locations will be consistent with the photographs included with this Restoration Plan.
