Physical characteristics of water resources in the study area Map ID H ight Banl�ful Depth Channel Velocity Clarity (ft) �'idth (ft) �ln� Substrate SA 4-8 45 24-48 Silt, Sand slow clear There are no designated Outstanding Resource Waters (ORW), High Quality Waters (HQW), or water supply watersheds (WS-I or WS-II) within 1.0 mile downstream of the study area. There are no designated anadromous fish waters or Primary Nursery Areas (PNA) present in the study area. Browns Creek does not appear on the North Carolina 2014 Fina1303(d) list of impaired waters. 4.0 BIOTIC RESOURCES 4.1 Terrestrial Communities Three terrestrial communities were identified in the study area: maintained/disturbed, Mesic Mixed Hardwood Forest (Coastal Plain Subtype), and Coastal Plain Small Stream Swamp (Blackwater Subtype). Figure 4 shows the location and extent of these terrestrial 2 October 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC communities in the study area. A brief description of each community type follows. Scientific names of all species identified are included in Appendix B. 4.1.1 Maintained/Disturbed The maintained/disturbed community occurs throughout the study area in places where the vegetation is periodically mowed or maintained, such as roadside shoulders, residential lawns, and utility easements. Dominant vegetation in this community is comprised of low growing grasses, herbs, and woody vines, including evening primrose, Chinese lespedeza, Japanese knotweed, ragweed, crabgrass, bicolor lespedeza, morning glory, muscadine grape, wooly mullein, fescue, passion flower, as well as mimosa, mockernut hickory, and smooth sumac saplings. 4.1.2 Mesic Mixed Hardwood Forest (Coastal Plain Subtype) The Mesic Mixed Hardwood Forest (Coastal Plain Subtype) is found in mesic upland areas protected from fires, primarily on north-facing river bluffs and ravine slopes, less commonly on upland flats or islands surrounded by peatland or swamp communities. This community exists in a portion of the northeast quadrant, and in the southeast and southwest quadrants of the study area. Dominant species in this community include white oak, tulip poplar, pignut hickory, and loblolly pine in the overstory. Ironwood, horse sugar, sweetgum, beech, American holly, beauty berry, sassafras, and Chinese privet comprise the midstory, while roundleaf greenbrier, muscadine grape, yellow jessamine, Japanese honeysuckle, blueberry, and ebony spleenwort dominate the understory. 4.1.3 Coastal Plain Small Stream Swamp (Blackwater Subtype) The Coastal Plain Small Stream Swamp (Blackwater Subtype) is found in the floodplains of small blackwater streams in which separate fluvial features and associated vegetation are too small or poorly developed to distinguish. This community bisects the project area into the northern and southern quadrants. Dominant species in this community include river birch, red maple, swamp chestnut oak, water oak, tulip poplar, and swamp tupelo in the overstory. Ironwood, titi, red bay, dog hobble, tag alder, buttonbush, and Chinese privet comprise the midstory, while Japanese stiltgrass, orange jewelweed, wisteria, netted chain fern, climbing hempvine, giant cane, roundleaf greenbrier, and tearthumb dominate the understory. Wetland site WA is classified as a North Carolina Wetland Assessment Method (NCWAM) Riverine Swamp Forest and is located within the Coastal Plain Small Stream Swamp (Blackwater Subtype) community. 4.1.4 Terrestrial Community Impacts Terrestrial communities in the study area may be impacted by project construction as a result of grading and paving of portions of the study area. At this time, decisions regarding the final location and design of the proposed bridge replacement have not been made. Therefore, community data are presented in the context of total coverage of each type within the study area (Table 4). Once a final alignment and preliminary design have been determined, probable impacts to each community type will be calculated.

Maintained/Disturbed 2.2 Mesic Mixed Hardwood Forest Coastal Plain Subt e 0.9 Coastal Plain Small Stream Swam (Blackwater Subt e 0.9 Total 4.0 4.2 Terrestrial Wildlife Terrestrial communities in the study area are comprised of both natural and disturbed habitats that may support a diversity of wildlife species (those species actually observed are indicated with *). Mammal species that commonly exploit maintained/disturbed habitats, forested habitats, wetlands, and stream corridors found within the study area include species such as eastern gray squirrel, gray fox, striped skunk, white-footed mouse, eastern cottontail, raccoon, Virginia opossum, beaver*, and white-tailed deer. Birds common to the area include red-shouldered hawk*, white-breasted nuthatch*, tufted titmouse*, barred owl*, northern cardinal*, fish crow*, American crow*, Carolina wren*, and summer tanager*. Reptile and amphibian species that may use terrestrial communities located in the study area include the rough green snake, green frog*, copperhead snake, rat snake, eastern box turtle, eastern fence lizard, southern toad, green anole, gray treefrog, and five-lined skink. 4.3 Aquatic Communities The aquatic community in the study area consists of a large perennial stream. Species that could be expected in Browns Creek include various shiners, white catfish, Eastern mudminnow, various sunfish, and various darters. 4.4 Invasive Species Eight species from the NCDOT Invasive Exotic Plant List for North Carolina were found to occur in the study area. Mimosa (Moderate threat), Japanese knotweed (Threat), Chinese lespedeza (Threat), Japanese honeysuckle (Moderate threat), and bicolor lespedeza (Moderate threat) were observed in the maintained-disturbed community. Chinese privet (Threat), Japanese stilt grass (Threat), and wisteria (Moderate threat) were observed in the Mesic Mixed Hardwood Forest (Coastal Plain Subtype) and Coastal Plain Small Stream Swamp (Blackwater Subtype) communities. NCDOT will manage for these invasive plant species as appropriate. 5.0 JURISDICTIONAL ISSUES 5.1 Clean Water Act Waters of the U.S. One jurisdictional stream (Browns Creek) was identified in the study area (Table 5). The location of this stream is shown on Figure 3. The physical characteristics and water 4 october 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC quality designations of Browns Creek are detailed in Section 3.2. Browns Creek has been designated as a warm water stream for the purposes of stream mitigation. Table 5.

Miti ation Re uired Buffer Browns Creek (SA) 200 Perennial Yes Not Sub�ect Total 200 One jurisdictional wetland was identified within the study area (Figure 3). Wetland classification and quality rating data are presented in Table 6. The single wetland identified in the study area is located within the Cape Fear River basin (USGS Hydrologic Unit 03030005). USACE wetland delineation and NCWAM wetland rating forms are included in Appendix C. Descriptions of the terrestrial communities at each wetland site are presented in Section 4.1. Table 6. Jurisdictional characteristics of wetlands in the study area NCWAM Hydrologic NCWAM Wetland Map ID Classification Classification Rating Area (ac.) WA I Riverine Swamn Forest Total 0.6 0.6 5.2 Clean Water Act Permits The proposed project has been designated as a CE for the purposes of National Environmental Policy Act (NEPA) documentation. As a result, a Nationwide Permit (NWP) No. 23 will likely be applicable. A NWP No. 33 may also apply for temporary construction activities such as stream dewatering, work bridges, or temporary causeways that are often used during bridge construction or rehabilitation. The USACE holds the final discretion as to what permit will be required to authorize project construction. If a Section 404 permit is required then a Section 401 Water Quality Certification (WQC) from the NCDWR will be needed. 5.3 Coastal Area Management Act Areas of Environmental Concern Bladen County is not a designated coastal county in North Carolina; therefore, Coastal Area Management Act (CAMA) regulations do not apply. 5.4 Construction Moratoria As of September 29, 2017, the North Carolina Wildlife Resources Commission (NCWRC) does not require an in-water construction moratorium for this project. 5 October 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC 5.5 N.C. River Basin Buffer Rules There are no buffer rules in effect for the lower Cape Fear River Basin. 5.6 Rivers and Harbors Act Section 10 Navigable Waters Browns Creek has not been designated by the USACE as a Navigable Water under Section 10 of the Rivers and Harbors Act. 5.7 Wetland and Stream Mitigation 5.7.1 Avoidance and Minimization of Impacts The NCDOT will attempt to avoid and minimize impacts to streams and wetlands to the greatest extent practicable in choosing a preferred alternative and during project design. At this time, no final decisions have been made with regard to the location or design of the preferred alternative. 5.7.2 Compensatory Mitigation of Impacts The NCDOT will investigate potential on-site stream and wetland mitigation opportunities once a final decision has been rendered on the location of the preferred alternative. If on-site mitigation is not feasible, mitigation will be provided by North Carolina Department of Environmental Quality (DEQ) Division of Mitigation Services (DMS). 5.8 Endangered Species Act Protected Species As of July 21, 2016 (Bladen County), the United States Fish and Wildlife (USFWS) lists seven federally protected species for Bladen County (Table 7). A brief description of each species' habitat requirements follows, along with the Biological Conclusion rendered based on survey results in the study area. Habitat requirements for each species are based on the current best available information from referenced literature andlor USFWS. 6 o�tobe� 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC Table 7.

The alligator is found in rivers, streams, canals, lakes, swamps, and coastal marshes. Adult animals are highly tolerant of salt water, but the young are apparently more sensitive, with salinities greater than 5 parts per thousand considered harmful. The American alligator remains on the protected species list due to its similarity in appearance to the Endangered American crocodile. Biological Conclusion: Not Required Species listed as threatened due to similarity of appearance do not require Section 7 consultation with the USFWS. However, an August 15, 2017 review of NCNHP database indicates no known American alligator occurrence within 1.0 mile of the study area. Red-cockaded woodpecker USFWS optimal survey window: year-round; November-early March (optimal) Habitat Description: The red-cockaded woodpecker (RCW) typically occupies open, mature stands of southern pines, particularly longleaf pine, for foraging and nesting/roosting habitat. The RCW excavates cavities for nesting and roosting in living pine trees, aged 60 years or older, and which are contiguous with pine stands at least 30 years of age to provide foraging habitat. The foraging range of the RCW is normally no more than 0.5 miles. 7 October 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC Biological Conclusion: No Effect Suitable habitat in the form of open, mature stands of southern pines used for foraging, nesting, and roosting were not present in the study area. Additionally, an August 15, 2017 review of NCNHP database indicates no known RCW occurrence within 1.0 mile of the study area. Subsequently, the proposed project will have No Effect on the red-cockaded woodpecker. Northern long-eared bat USFWS Recommended Survey Window: June 1— August 15 Habitat Description: In North Carolina, the Northern long-eared bat (NLEB) occurs in the mountains, with scattered records in the Piedmont and coastal plain. In western North Carolina, NLEB spend winter hibernating in caves and mines. Since this species is not known to be a long-distance migrant, and caves and subterranean mines are extremely rare in eastern North Carolina, it is uncertain whether or where NLEB hibernate in eastern North Carolina. During the summer, NLEB roost singly or in colonies underneath bark, in cavities, or in crevices of both live and dead trees (typically >3 inches dbh). Males and non-reproductive females may also roost in cooler places, like caves and mines. This bat also been found, rarely, roosting in structures like barns and sheds, under eaves of buildings, behind window shutters, in bridges, and in bat houses. Foraging occurs on forested hillsides and ridges, and occasionally over forest clearings, over water, and along tree-lined corridors. Mature forests may be an important habitat type for foraging. Biological Conclusion: May Affect, Likely to Adversely Affect The US Fish and Wildlife Service has developed a programmatic biological opinion (PBO) in conjunction with the Federal Highway Administration (FHWA), the US Army Corps of Engineers (USACE), and NCDOT for the northern long-eared bat (NLEB) (Myotis septentrionalis) in eastern North Carolina. The PBO covers the entire NCDOT program in Divisions 1-8, including all NCDOT projects and activities. The programmatic determination for the NLEB for the NCDOT program is "May Affect, Likely to Adversely AffecY'. The PBO provides incidental take coverage for the NLEB and will ensure compliance with Section 7 of the Endangered Species Act for five years for all NCDOT projects with a federal nexus in Division 1-8, which includes Bladen County, where Bridge 080178 is located. Wood stork USFWS Recommended Survey Window: June-September Habitat Description: Wood storks are known to occur in several coastal North Carolina counties, and records indicate that they have been breeding in North Carolina since 2005. Wood storks typically construct their nests in medium to tall trees that occur in stands located either in swamps or on islands surrounded by relatively broad expanses of open water. In many areas, bald 8 October 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC cypress and red mangrove trees are preferred. During the nonbreeding season or while foraging, wood storks occur in a wide variety of wetland habitats, including freshwater marshes and stock ponds, shallow, seasonally flooded roadside or agricultural ditches, narrow tidal creeks or shallow tidal pools, managed impoundments, and depressions in cypress heads and swamp sloughs. Because of their specialized feeding behavior, the most attractive feeding areas are swamp or marsh depressions where fish become concentrated during dry periods. Biological Conclusion: Unresolved Suitable habitat in the form of inedium to tall trees that occur in stands located either in swamps or on islands surrounded by relatively broad expanses of open water was present in the study area. However, an August 30, 2017 survey of the project area revealed no individuals of wood stork. Additionally, an August 15, 2017 review of NCNHP database indicates no known wood stork occurrence within 1.0 mile of the study area. Pending surveys by the NCDOT personnel the biological conclusion for the wood stork remains unresolved. American chaffseed USFWS Optimal Survey Window: May-August (1-2 months after a fire) Habitat Description: American chaffseed generally occurs in habitats described as open, moist to dryish Mesic Pine Flatwoods and longleaf pine flatlands, Pine Savannas, Pine/Scrub Oak Sandhills, Sandhill Seeps, and other open grass/sedge-dominated communities. This herb also occurs in the ecotonal areas between peaty wetlands and xeric sandy soils and on the upper ecotones of, or sites close, to Streamhead Pocosins. The species prefers sandy peat or sandy loam, acidic, seasonally moist to dry soils in sunny or partly sunny areas subject to frequent fires in the growing season. The plant is dependent on factors such as fire, mowing, or fluctuating water tables to maintain its required open to partly-open habitat. Most extant occurrences, and all of the most vigorous occurrences, are in areas subject to frequent fire. This species is also known to occur on road cuts and power line rights-of-way that experience frequent mowing or clearing. Soil series that it is found on include Blaney, Candor, Gelead, Fuquay, Lakeland, and Vaucluse. Biological Conclusion: No Effect Suitable habitat in the form of open, moist to dryish Mesic Pine Flatwoods and longleaf pine flatlands, Pine Savannas, Pine/Scrub Oak Sandhills, Sandhill Seeps, and other open grass/sedge-dominated communities was not present in the study area. Additionally, an August 15, 2017 review of NCNHP database indicates no known occurrences within 1.0 mile of the study area. Subsequently, the proposed project will have No Effect on the American chaffseed. 9 o�tobe� 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC Pondberry USFWS Optimal Survey Window: February-October Habitat Description: Pondberry occurs in seasonally flooded wetlands, sandy sinks, pond margins, and swampy depressions. This deciduous, aromatic shrub occurs in bottomland hardwood forests with perched water tables along inland areas of the southeastern United States. In the Coastal Plain of the Carolinas, the species occurs at the margins of limestone sinks and ponds and in undrained, shallow depressions of longleaf pine and pond pine forests. Known occurrences in North Carolina occur in the Small Depression Pocosin natural community, grow in soils with sandy sediments and high-water table, contain high peat content in the subsurface, and include a prevalence of shrubs due to historically frequent or intense fires. It generally grows in somewhat shaded areas, but can tolerate full sun. Biological Conclusion: No Effect Suitable habitat in the form of seasonally flooded wetlands, sandy sinks, pond margins, and/or swampy depressions was present in the study area. However, an August 30, 2017 survey of the study area revealed no individuals of Lindera species present. Additionally, an August 15, 2017 review of NCNHP database indicates no known occurrences within 1.0 mile of the study area. Subsequently, the proposed project will have No Effect on the Pondberry. Rough-leaved loosestrife USFWS Optimal Survey Window: mid-May-June Habitat Description: Rough-leaved loosestrife, endemic to the Coastal Plain and Sandhills of North and South Carolina, generally occurs in the ecotones or edges between longleaf pine uplands and pond pine pocosins in dense shrub and vine growth on moist to seasonally saturated sands and on shallow organic soils overlaying sand (spodosolic soils). Occurrences are found in such disturbed habitats as roadside depressions, maintained power and utility line rights-of-way, firebreaks, and trails. The species prefers full sunlight, is shade intolerant, and requires areas of disturbance (e.g., clearing, mowing, periodic burning) where the overstory is minimal. It can, however, persist vegetatively for many years in overgrown, fire-suppressed areas. Blaney, Gilead, Johnston, Kalmia, Leon, Mandarin, Murville, Torhunta, and Vaucluse are some of the soil series that the plant occurs on. Biological Conclusion: Unresolved Suitable habitat in the form of disturbed habitats as roadside depressions, maintained power and utility line rights-of-way, firebreaks, and trails was present in the study area. However, an August 30, 2017 survey of the study area revealed no individuals of rough-leaved loosestrife present. Additionally, an August 15, 2017 review of NCNHP database indicates no known occurrences within 1.0 mile of the study area. Pending surveys by the NCDOT personnel in the appropriate 10 October 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC survey window the biological conclusion for the rough-leaved loosestrife remains unresolved. 5.9 Bald Eagle and Golden Eagle Protection Act Habitat for the bald eagle primarily consists of mature forest in proximity to large bodies of open water for foraging. Large dominant trees are utilized for nesting sites, typically within 1.0 mile of open water. A desktop-GIS assessment of the project study area, as well as the area within a 1.0-mile radius of the project limits, was performed on August 15, 2017 using 2014 color aerials. There are two ponds > 2 acres in size located within 1 A miles of the project study area. A visual survey for nest trees within 660 feet of the project study area was conducted on August 30, 2017. No nest trees were observed. Additionally, a review of the NCNHP database on August 15, 2017, revealed no known occurrences of this species within 1.0 mile of the project study area. The project is not expected to have any adverse effects on the bald eagle. 5.10 Endangered Species Act Candidate Species As of July 21, 2016, the USFWS lists no Candidate species for Bladen County. 5.11 Essential Fish Habitat Bladen County is considered an inland county. No Essential Fish Habitat is present in or within 1.0 mile of the study area. 11 October 2017 Natural Resources Technical Report Bridge 080178, Bladen County, NC 6.0 REFERENCES Burt, W.H. and R.P.
