Director Division of Water Quality June 4, 2002 Mr. Bill Gilmore, P.E., Manager Planning and Environmental Branch North Carolina Department of Transportation 1548 Mail Service Center Raleigh, North Carolina, 27699-1548 Re: Permit Application for proposed Replacement of Bridge Number 91 on SR 1509 over Parrot Swamp in Onslow County DWQ No. 020670, TIP No. B-3358 Dear Mr. Gilmore: The Division of Water Quality has reviewed your submittal for a 401 Water Quality Certification for the aforementioned project. Review of your application revealed it lacking necessary information required for making an informed permit decision. The permit application was deficient in the following areas: • The project proposes the use of the Clayhill Mitigation Site. At present, the Mitigation Banking Review Team has not completed the development of the Mitigation Banking Instrument (MBI) for this site. Therefore, no credits are presently available for use from this site. As soon as the MBI for this site is signed, mitigation credits will potentially be available for this project. While the project as proposed does not meet the minimum threshold for the General Certification 3361 to require written concurrence from the North Carolina Division of Water Quality, the DWQ has the option to require an individual certification if "it is determined that the project is likely to have a significant adverse effect upon water quality or degrade the waters so that existing uses of the wetland or downstream waters are precluded". The project proposes the placement of temporary fill into SA waters and wetlands immediately adjacent to SA waters. The NCDWQ requests that DOT please redesign the project to use a temporary work bridge instead of a temporary fill causeway, or the Division of Water Quality may have to require an individual certification for this project and condition the certification accordingly. Therefore, pursuant to 15A NCAC 2H .0507(a)(5), we will have to place the permit application on hold until we are supplied the necessary information. Furthermore, until the information is received by the NC Division of Water Quality, we request (by copy of this letter) that the US Army Corps of Engineers place the permit application on hold.

Department of Environment and Natural Resources V20V6, Division of Coastal Management ?' 151-B Hwy 24 Hestron Plaza II Morehead City, NC 28557 ATTENTION Dear Mr. Tyndall: Mr. Ted Tyndall District Manager Subject: Onslow County, CAMA Major Development Permit Application for the replacement of Bridge No. 91 over Parrot Swamp on SR 1509, NCDOT Division 3, Federal Aid Project No. MABRZ-1509(4), State Project No. 8.2260901, TIP Project No. B-3358. Please find enclosed copies of the Categorical Exclusion (CE), an Addendum to the CE, the Coastal Area Management Act (CAMA) permit application, permit drawings, a letter from the Coast Guard, a North Carolina Division of Water Quality (DWQ) Stormwater Exemption letter, and a check for $400.00 for the application fee for the above referenced project. Bridge No. 91 will be replaced on the existing alignment with a new bridge approximately 60 feet (18.0 meters) in length and 40 feet (12.0 meters) in width. The new bridge will have two 12.0 foot (3.6 meters) travelways with 8.0 foot (2.4 meters) rail offsets. The approach roadway will consist of two 12.0-foot (3.6-meter) lanes with grassed shoulders at least 8.0 foot (2.4 meters) wide. During construction, traffic will be maintained on a temporary on-site detour west of the existing bridge. The length of the temporary detour will be approximately 700 feet (213.0 meters) with a temporary bridge approximately 60.0 feet (18.2 meters) in length. Impacts to wetlands associated with the replacement of Bridge No. 91 will include temporary fill and mechanized clearing due to the temporary detour. Mechanized clearing will be by Method III. Parrot Swamp is classified as SA waters by the Division of Water Quality and is designated by North Carolina Division of Marine Fisheries as a Primary Nursery Area. Therefore, NCDOT will strictly adhere to "Design Standards in Sensitive Watersheds" (15A NCAC 04B .0024) (High Quality Water Standards) throughout design and construction of this project. Temporary Bridge Information: A temporary bridge will be located west of the existing bridge. The temporary bridge will consist a concrete deck with Class II riprap on top of filter fabric. The resulting temporary fill in wetlands associated with the temporary detour bridge is 0.17 acre (0.07 hectare) and approximately 0.06 acre (0.02 hectare) in mechanized clearing. Restoration Plan: Upon completion of the new bridge, the temporary bridge will be removed. The approach fill will be removed to natural grade (Elevations and contours in the vicinity are available from field survey notes). The area will be planted with appropriate native wetland species. Minimization: The original alternate chosen involved placing the temporary detour bridge on the eastern side of SR 1509. After evaluation by the NCDOT Natural Systems Staff, it was concluded that the wetlands on the east are comparatively higher quality than the wetlands on the western side of SR 1509. Therefore, the decision was made to move the temporary detour to the west side in order to decrease the amount of higher quality wetlands impacted. Detour fill slopes have been reduced to 2:1 to reduce roadway fill. Mitigation: All project impacts are considered permanent since compression of muck soils may have permanent negative environmental consequences. A total of 0.23 acre (0.09 ha) of riverine wetland impacts will occur on this project. NCDOT proposes to debit the Clayhill Farms mitigation bank. This site is located northeast of Jacksonville in Jones County. Schedule: The project schedule calls for an October 15, 2002 let date with an availability date approximately six weeks after. It is expected that the contractor will choose to start construction of the temporary detour bridge shortly after the availability date. The temporary bridge will be removed within 90 days upon completion of the project. Disposal: After the temporary bridge is no longer needed, the contractor will use roadway building equipment to remove the concrete deck and riprap. All temporary bridge material will become the property of the contractor. The contractor will be required to submit a reclamation plan for removal and disposal of all material off-site. Bridge Demolition: Bridge No. 91 contains two main spans totaling 36 feet (11.0 meters) and is 26 tet (7.9 meters) wide. The bridge has a reinforced concrete floor on timber joists and the substructure is reinforced concrete caps on timber piles. Both the bridge rail and substructure will be removed without dropping components into Waters of the United States. There is potential for components of the deck to be dropped into Waters of the United States during construction. The resulting temporary fill associated with the concrete deck is approximately 10.0 yd3 (7.6 m3). However, it is anticipated that the bridge will be removed without dropping components into the river. During construction, Best Management Practices for Bridge Demolition and Removal will be followed. Threatened and Endangered Species: As of February 26, 2001, the U.S. Fish and Wildlife Service (USFWS) lists ten federally protected species for Onslow County. On January 23, 2002 the USFWS determined the endangered status for golden sedge (Carex lutea); therefore, golden sedge was added to the federally protected species list for Onslow County. The NCDOT evaluation of the original ten species in November of 1998 and June of 1999 resulted in Biological Conclusions of "No Effect" for all of these species. A survey has not been conducted for the golden sedge and additional surveys will be conducted for rough-leaved loosestrife (Lysimachia asperulaefolia) and Cooley's meadowrue (Thalictrum cooleyi). Therefore, surveys for goldensedge, rough-leaved loosestrife, and Cooley's meadowrue will be conducted prior to project construction. The results of these surveys will be forwarded to the resource agencies as soon as they are available. A review of the NC Natural Heritage Program database of rare species and unique habitats on January 7, 2002 revealed that no known occurrences of any federally protected species occur within one mile of the project area. NCDOT requests that the proposed work be authorized under a Coastal Area Management Act Major Development Permit. A check for $400.00 for the application fee is enclosed. Copies of the green cards will be forwarded as soon as they are available. By copy of this letter, we are also requesting issuance of a United States Army Corps of Engineers NWP 23 and a 401 Water Quality Certification from the North Carolina Division of Water Quality.

Categorical Exclusion April 2000, Onslow County Bridge No. 91 on SR 1509 Over Parrot Swamp Federal Project MABRZ-1509 (4) State Project 8.2260901 TIP No. B-3358 The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge No. 91 in Onslow County (see Figure 1). This bridge carries SR 1509 over Parrot Swamp. This project is included in NCDOT's 2000-2006 Transportation Improvement Program (TIP) as a bridge replacement project. NCDOT and the Federal Highway Administration (FHWA) classify this project as a Categorical Exclusion. No substantial environmental impacts are expected. I. SUMMARY OF RECOMMENDATIONS Bridge No. 91 will be replaced as recommended in Alternate 3 with a bridge on new alignment approximately 18 meters (60 feet) east of the existing structure (see Figure 2). The new structure will be a approximately 18 meters (60 feet) in length. The clear roadway width of the bridge will be 12 meters (40 feet) to accommodate two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) rail offsets. The roadway approaching the bridge will consist of two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) grassed shoulders. The new bridge will be at approximately the same elevation as the existing bridge. Based on preliminary design, the design speed will be 100 km/h (60 mph). Traffic will be detoured on the existing alignment during construction. .. The estimated cost of the project is $1,018,000 including $950,000 in construction costs and $68,000 in right of way costs. The estimated cost shown in the 2000-2006 TIP is $325,000. The current estimated cost of the proposed improvements exceeds the TIP funding by $693,000. Right of way acquisition for the project is scheduled to begin in fiscal year 2001 and construction is scheduled to begin in fiscal year 2002. II. ANTICIPATED DESIGN EXCEPTIONS There are no design exceptions currently associated with this project. A final determination on design exceptions will be made during the design phase for the project. III. EXISTING CONDITIONS SR 1509 is classified as a Rural Minor Collector in the Statewide Functional Classification System. It is located approximately 5.6 kilometers (3.5 miles) south of Swansboro, N. C. The posted speed limit in the vicinity of the bridge is 90 km/h (55 mph). There were four reported accidents in the vicinity of the bridge during the three-year period from August 1, 1994, to July 31, 1997. The existing bridge was built in 1959. The bridge includes two main spans totaling 11.0 meters (36 feet) in length and is 7.9 meters (26 feet) wide. It has a reinforced concrete floor on timber joists and the substructure has reinforced concrete caps on timber piles. The bridge carries two lanes of traffic and has a 7.2-meter (24-foot) roadway width. The approach roadway is 6.1 meter (20 feet) wide with grass shoulders. It is approximately 3.6 meters (12 feet)-above the streambed. Both the bridge rail and substructure will be removed without dropping them into Waters of the United States. There is potential for components of the deck to be dropped into Waters of the United States during construction. The resulting temporary fill associated with the concrete deck is approximately 7.6 m3(10 yd3). According to Bridge Maintenance Unit records, the sufficiency rating of the bridge is 46.5 out of a possible 100. Presently the bridge is posted with weight restrictions of 18 tons for single vehicles and 25 tons for truck-tractor semi-trailers. The Traffic Forecasting Unit has indicated that near Bridge No. 91, SR 1509 carries 6,200 vehicles per day in the year 2000. This figure is expected to increase to 12,100 vehicles per day by the year 2025. These traffic figures include 3% dual tired vehicles [DUAL], and 1% truck-tractor semi-trailers [TTST]. The design hourly volume [DHV] is 10%. The Onslow County School Bus Transportation Coordinator indicated that 25 school buses each cross this bridge as many as 6 times per day during the school year. IV. STUDIED ALTERNATES A. Alternative 1 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. Two residences will be relocated as a 2 result of construction of this alternate. B. Alternative 2 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour east of the existing bridge during construction. One business will be relocated as a result of construction of this alternate. C. Alternative 3 (Recommended) Replace Bridge No. 91 on new alignment to the east of the existing bridge with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on the existing bridge during construction. Two residences will be relocated as a result of construction of this alternate. D. Other Alternatives The "do-nothing" alternative is not practical; requiring the eventual closing of the road as the existing bridge completely deteriorates. Rehabilitation of the existing deteriorating bridge is neither practical nor economical. An alternative with an off-site detour is not reasonable. The shortest detour route is more than 19 kilometers (12 miles) in length (see Figure 1). This would generate a much greater cost to the average road user during the course of construction than an on-site detour. An off-site detour is also undesirable due to the resulting community impacts. Two schools have recently been constructed in the area. As mentioned above, 25 school buses each cross the bridge as many as 6 times per day during the school year. Closing the bridge during construction would cause substantial delays for these buses and would be an obstacle to school bus operations. V.

RECOMMENDED IMPROVEMENTS Bridge No. 91 will be replaced as recommended in Alternate 3 with a bridge on new alignment approximately 18 meters (60 feet) east of the existing structure (see Figure 2). The new structure will be a approximately 18 meters (60 feet) in length. The clear roadway width of the bridge will be 12 meters (40 feet) to accommodate two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) rail offsets. The roadway approaching the bridge will consist of two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) grassed shoulders. The new bridge will be at approximately the same elevation as the existing bridge. Based on preliminary design, the design speed will be 100 km/h (60 mph). Traffic will be detoured on the existing alignment during construction. Upon completion of the new bridge, the existing bridge will be removed. The existing approach fill will be removed to natural grade and the area will be planted with native grasses and/or tree species as appropriate. Alternate 3 is recommended because it has the lowest cost of the alternates considered. Also, there is a relatively small difference in environmental impacts between the alternatives. The Division concurs with the recommendation. 4 VII. ENVIRONMENTAL EFFECTS A. General This project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. This project is considered to be a "Categorical Exclusion" due to its limited scope and insignificant environmental consequences. This bridge replacement will not have a substantial adverse effect on the quality of the human or natural environment by implementing the project commitments listed in the front of this document, and by using current NCDOT standards and specifications. The project is not in conflict with any plan, existing land use, or zoning regulation. No change in land use is expected to result from construction of this. project. There are no hazardous waste impacts. No adverse effect on families or communities is anticipated. Right-of-way acquisition will be limited. Two residences will be relocated as a result of construction of the project. No adverse effect on public facilities or services is expected. The project is not expected to adversely affect social, economic, or religious opportunities in the area. There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of national, state, or local significance in the vicinity of the project. The proposed bridge replacement project will not raise the existing flood levels or have any significant adverse effect on the existing floodplain. Utility conflicts will be medium for the project. There is a water line along the east side of SR 1509. There are aerial telephone and power lines along the west side of SR 1509. There is a fiber-optic cable on the west side of SR 1509, which is above ground across the swamp. 5 B. Air And Noise This project is an air quality "neutral" project, so it is not required to be included in the regional emissions analysis and a project level CO analysis is not required. If vegetation is disposed of by burning, all burning shall be done in accordance with applicable local laws and regulations of the North Carolina SIP for air quality in compliance with 15 NCAC 2D.0520. The project will not substantially increase traffic volumes. Therefore, it will not have substantial impact on noise levels. Temporary noise increases may occur during construction. C. Land Use & Farmland Effects In the vicinity of this project, Onslow County has no zoning. This project will impact no soils considered to be prime or important farmland. D. . Historical Effects & Archaeological Effects The State Historic Preservation Office (SHPO) has indicated that there are no known historic architectural resources in the project area. Therefore, SHPO has recommended that no historic architectural survey be conducted for the project (see letter dated November 1Z 1997, in the appendix). The State Historic. Preservation Office (SHPO) has indicated that there are no known archaeological sites in the project area and no unknown sites are likely to be found. Therefore, SHPO has recommended that no archaeological investigation be conducted for the project (see letter dated November 12,1997, in the appendix). E. Natural Resources 1. Methodology Research was conducted prior to field investigations. Information sources used in this pre-field investigation of the study area include: U.S. Geological Survey (USGS) quadrangle map (Hubert), U.S. Fish and Wildlife Service (FWS) National Wetland Inventory Map (Hubert), 6 Department of Agriculture (Soil Conservation Service) soil maps (Onslow County), and NCDOT aerial photographs of project area (1:1200). Water resource information was obtained from publications of the Department of Environment and Natural Resources (DENR,1997) and from the NC Center for Geographic Information and Analysis (Environmental Sensitivity Base Map of Onslow County, 1995). Information concerning the occurrence of federal and state protected species in the study area was gathered from the Fish and Wildlife Service (FWS) list of protected species and species of concern, and the N.C. Natural Heritage Program (NHP) database of rare species and unique habitats. General field surveys were conducted along the proposed alignment by NCDOT biologists Susan Brady and Logan Williams on 2 November 1998. Plant communities and their associated wildlife were identified and recorded. Wildlife identification involved using one or more of the following observation techniques: active searching and capture, visual observations (binoculars), and identifying characteristic signs of wildlife (sounds, scat, tracks and burrows). Jurisdictional wetland determinations were performed utilizing delineation criteria prescribed in the "Corps of Engineers Wetland Delineation Manual" (Environmental Laboratory, 1987). Additional surveys for federally-protected species were conducted by NCDOT biologists Dale Suiter and Jim Hauser on 22 June 1999. 2. Physical Resources Soil and water resources occurring in the study area are discussed below. Soils and availability of water directly influence composition and distribution of flora and fauna in any biotic community. The project study area lies within the Coastal Plain Physiographic Province. The topography in this section of Onslow County is nearly flat to gently sloping, dissected by floodplains. Topography in the project area is somewhat sloping since it is located in the stream valley and floodplain area associated with Parrot Swamp. Project elevation is approximately 4.6 m (15.0 ft) above mean sea level (msl). a. Soils Three soil phases occur within project boundaries: Muckalee loam, Marvyn loamy fine sand 6-15% slope, and Norfolk loamy fine sand 2-6% slope. Muckalee loam is a poorly drained soil occurring on flood plains. Permeability is moderate, surface runoff is slow, and the seasonal high 7 water table is located at 0.1-0.5 m (0.5-1.5 ft) below the surface. Flooding occurs frequently for brief periods, and water may pond in the wider floodplains for long periods in winter. Muckalee loam is -listed as hydric. Marvyn loamy sand 6-15% slope is a well-drained soil occurring short side slopes near large drainageways on uplands. Permeability is moderate, surface runoff is medium, and the seasonal high water table is located 0.9-1.5 m (3.0-5.0 ft) below the surface. This soil is subject to erosion if not protected by vegetation. Marvyn loamy fine sand 6-15% slope is listed as non-hydric, but may contain hydric inclusions of the Muckalee soil type. Norfolk loamy fine sand 2-6% slope is a well-drained soil occurring on uplands. Permeability is moderate, surface runoff is medium, and the seasonal high water table is located 1.1-1.8 m (3.5-6.0 ft) below the surface. Norfolk loamy fine sand is subject to erosion if not protected by cover vegetation, and is listed as non-hydric. Muckalee loam is difficult to manage for croplands and timber due to wetness and flooding, however, woodland productivity is rated as excellent. Wetness, periodic flooding, bank instability, and seepage are the major limitations for this soil. Marvyn loamy fine sand 6-15% slope is mainly used as woodland, with the major limitations for this soil being the slope and risk of erosion. Norfolk loamy fine sand 2-6% slope is used mainly for cropland. The major limitations of this soil are erosion where vegetation has been removed and, in areas used for building or sanitary facilities, high water table during wet periods. Soil core samples taken throughout the project area revealed soils with a sandy/ silty texture. The soils did exhibit hydric conditions, such as low chroma colors, in low areas of the flood plain. Therefore, hydric soil indicators, as defined in the "Corps of Engineers Wetland Delineation Manual", 1987, were observed within the project study area. b. Water Resources This section contains information concerning those water resources likely to be impacted by the project. Water resource information encompasses physical aspects of the resource, its relationship to major water systems, Best Usage Standards and water quality of the resources. Probable impacts to these water bodies are also discussed, as are means to minimize impacts. 8 Waters Impacted and Characteristics Parrot Swamp will be the only surface water resource directly impacted by the proposed project. Parrot Swamp is located in sub-basin 030501 of the White Oak River Basin. Parrot Swamp is a tributary to Queen Creek, and -has its confluence with the creek approximately 3.2 km °" (2.0 mi stream channel distance) downstream of Bridge No. 91. Queen Creek is a 3.1 km (10.1 mi) long coastal stream flowing into the White Oak River estuary in the vicinity of the town of Swansboro and Bogue Inlet. Parrot Swamp, at Bridge No. 91, is approximately 3.0 m (10.0 ft) wide and has an average depth of 0.6-0.9 m (2.0-3.0 ft) at this location. The substrate is composed of silt, sand and gravel. Parrot Swamp is a blackwater stream, with a visibility of less than 0.6 m (2.0 ft). Best Usage Classification The Division of Water Quality (DWQ) has assigned streams a best usage classification. The classification of Parrot Swamp [index no. 19-41- 16-4] is SA. The SA classification denotes waters suitable for shellfishing for market purposes, primary recreation, aquatic life propagation and survival, fishing, wildlife, and secondary recreation. The classification of SA automatically includes Parrott Swamp in the supplemental classification of High Quality Waters (HQW). No Water Supplies (WS-I: undeveloped watersheds or WS-II: predominately undeveloped watersheds) or Outstanding Resource Waters (ORW) occur within 1.6 km (1.0 mi) of project study area. Water ality The DWQ has initiated a whole basin approach to water quality management for the 17 river basins within the state. To accomplish this goal the DWQ, formerly known as the Department of Environmental Management (DEM), collects biological, chemical and physical data that can be used in basinwide assessment and planning. All basins are reassessed every five years. Prior to the implementation of the basinwide approach to water quality management, the Benthic Macroinvertebrate Ambient Network (managed by the DEM) assessed water quality by sampling for benthic macroinvertebrate organisms at fixed monitoring sites throughout the state. Some macroinvertebrates are sensitive to very subtle changes in water quality; thus, the species richness and overall biomass of these organisms are reflections of water quality. A benthic 9 macroinvertebrate collection site is located at the mouth of Queen Creek in Onslow County, approximately 4.8 km (3.0 mi stream channel distance) from the project study area. This station was sampled once in August 1994 and received a taxa richness rating of 103, a Biotic Index value of 2.3, and a bioclassification of Estuarine (DWQ, 1997). The Ambient Monitoring System (AMS) is a network of stream, lake and estuarine water quality monitoring stations strategically located for the collection of physical and chemical water quality data. The type of water quality data or parameters that are collected is determined by the waterbody's freshwater or saltwater classification and corresponding water quality standards (DWQ 1997). Data collected at an AMS monitoring site at the mouth of the White Oak River (NC 24 at Swansboro) between January 1990 and December 1994 show no excursions from NC Water Quality Criteria for all tested parameters except copper (DWQ 1997). The increased levels of copper are seen throughout the whole basin, and are therefore probably not due to a point source. Parrot Swamp is, however, listed as a partially supporting impaired water due to fecal coliform contamination, and shellfishing in this area has been prohibited or restricted (DWQ 1997). Point source dischargers located throughout North Carolina are permitted through the National Pollutant Discharge Elimination System (NPDES) Program. Any discharger is required to register for a permit. In June 1998, DWQ issued a NPDES permit to NCDOT authorizing it to discharge stormwater into Waters of the United States. No other point source dischargers are located within a 1.6 km (1.0 mi) radius of the project study area. Summary of Anticipated Impacts Replacing an existing structure in the same location with a temporary detour during construction is almost always preferred to relocating the road entirely. It poses the least risk to aquatic organisms and other natural resources, whereas bridge replacement on a new location usually results in more severe impacts. Alternates 1 and 2 involve the current right of way and a temporary detour. Utilizing the full existing right of way width of 18.3 m (60.0 ft) and temporary detour width of 30.5 m (100.0 ft), anticipated impacts to Parrot Swamp for Alternate 1 will be 48.8 m (160.0 ft) and Alternate 2 will be 39.6 m (130.0 ft). Alternate 3 calls for relocation of the bridge, using the existing bridge as a detour during construction. Utilizing the full existing right of way width of 18.3 m (60.0 ft) and new right of way width of 30.5 m (100.0 ft), anticipated impacts to Parrot Swamp for Alternate 3 will be 48.8 m (160.0 ft). Usually, 10 project construction does not require the entire right of way, therefore, actual impacts may be considerably less. Project construction for any of the three alternates may result in the following impacts to surface waters: 1. Increased sedimentation and siltation from construction and/or erosion. 2. Changes in light incidence and water clarity due to increased sedimentation and vegetation removal. 3. Alteration of water levels and flows due to interruptions and/ additions to surface and ground water flow from construction. 4. Changes in water temperature due to streamside vegetation removal. 5. Increased nutrient loading during construction via runoff from exposed areas. 6. Increased concentration of toxic compounds from highway runoff, construction and toxic spills. Precautions will be taken to minimize impacts to water resources in the study area. NCDOT's Best Management Practices (BMP) for the Protection of Surface Waters and Sedimentation Control guidelines in Sensitive Watersheds will be strictly enforced during the construction stage of the project. Provisions to preclude contamination by toxic substances during the construction interval will also be strictly enforced. 3. Biotic Resources Biotic resources include aquatic and terrestrial ecosystems. This section describes those ecosystems encountered in the study area, as well as the relationships between fauna and flora within these ecosystems. Composition and distribution of biotic communities throughout the project area are reflective of topography, hydrologic influences and past and present land uses in the study area. Descriptions of the terrestrial systems are presented in the context of plant community classifications and follow descriptions presented by Schafale and Weakley (1990) where possible. Dominant flora and fauna observed, or likely to occur, in each community are described and discussed. 11 Scientific nomenclature and common names (when applicable) are provided for each animal and plant species described. Plant taxonomy generally follows Radford, et al. (1968). Animal taxonomy follows Martof, et al. (1980), Menhenick (1991), Potter, et al. (1980), and Webster, et al. (1985). Subsequent references to the same organism will include the common name only. Fauna observed during the site visit are denoted by an asterisk (*). Published range distributions and habitat analysis are used in estimating fauna expected to be present within the project area. a. Biotic Communities Five communities are identified in the project study area: Coastal Plain Small Stream Swamp (Blackwater Subtype), Bottomland Hardwoods (Blackwater Subtype), Coastal Plain Perennial Stream, Mesic Pine Flatwoods, and maintained/ disturbed. Community boundaries within the study area are well defined without a significant transition zone between them, except in the case of the Coastal Plain Small Stream Swamp, which merges into the Bottomland Hardwoods. Faunal species likely to occur within the study area will exploit all communities for shelter and foraging opportunities or as movement corridors, except those fauna restricted. to the aquatic environment. Coastal Plain Small Stream Swamp (Blackwater Subtyye) The Coastal Plain Small Stream Swamp is present along the Parrot Swamp corridor on both sides of SR 1509. The hydrology of this . community type is driven by intermittent flooding during high flow periods. Periodic flooding provides nutrient input through sediment deposition making this system very productive. However, periodic flooding can also be a destructive factor during large storm events by undercutting banks and eroding soils. The canopy is composed of American elm (Ulmus americana), tulip poplar (Liriodendron tulipifera), green ash (Fraxinus pennsylvanica), red maple (Acer rubrum), red bay (Persea borbonia), loblolly pine (Pinus taeda), water oak (Quercus nigra) and sweetgum (Liquidambar styraciflua). The shrub layer consists of saplings of the canopy trees, Virginia willow (Itea virginica), Chinese privet (Ligustrum sinense), common waxmyrtle (Myrica cerifera) and tag alder (Alnus serrulata). Flowering dogwood (Corpus florida) and persimmon (Diospyros virginiana) were occasionally found on isolated hummocks within the floodplain. Herbs within this community include net-veined chain fern (Woodwardia areolata), sedges (Carex spp.), and smartweed (Polygonum lapathifolium). The vine layer is composed of 12 Japanese honeysuckle (Lonicera japonica), climbing hempweed (Mikania scandens), climbing hydrangea (Decumeria Barbara) and greenbrier (Smilax bona-nox). Bottomland Hardwoods (Blackwater Subtype) Bottomland hardwoods are present on both sides of the project area, adjacent to the Coastal Plain Small Stream Swamp. The hydrology of this community is also driven by seasonal or intermittent flooding; however, this community tends to be farther from the stream channel than the Coastal Plain Small Stream Swamp. The canopy layer in this community consists of loblolly pine, red maple and sweetgum. The shrub layer consists of saplings of the canopy trees, American holly (Ilex opaca), and Virginia willow. The herb layer includes smartweed and net-veined chain fern. The vine layer is composed of Japanese honeysuckle, kudzu (Peuraria lobata), poison ivy (Toxicodendron radicans) and greenbrier. Mesic Pine Flatwoods The Mesic Pine Flatwoods area is confined to the extreme northern and southern ends of the project, on both sides of the road. This area has sandy soils and is higher in elevation than the rest of the project. This community appears to be disturbed by human activity. The canopy layer in this community consists of loblolly pine and sweetgum. The shrub layer consists of saplings of the canopy trees, persimmon, and occasional flowering dogwoods. The herb layer includes aster (Aster spp.) and goldenrod (Solidago spp.). The vine layer is composed of Japanese honeysuckle, kudzu, poison ivy and greenbrier. Maintained/ Disturbed The maintained/ disturbed community is restricted to road shoulders along SR 1509 and the area around the bridge and is present along the entire length of the project. Flora within this periodically maintained community includes: fescue (Festuca spp.), goldenrod, dock (Rumex spp.), paspalum (Paspalum spp.), beggar-ticks (Bidens spp.), snumtweed, ragweed (Ambrosia artemesiifolia), and calico aster (Aster lateriflorus). The area immediately around the bridge, which is less intensively maintained, also contains black willow (Salix nigra). Eastern red cedar (Juniperus virginiana), is occasionally seen in the woods along the edge of this community. 13 Coastal Plain Perennial Stream This area of Parrot Swamp is a small blackwater.stream. The only vegetation associated with the stream itself in this area is smartweed and beggar-ticks, both of which were growing into the stream channel in the vicinity of the bridge. There is no visible submerged aquatic vegetation. b. Wildlife The physical characteristics of the terrestrial and aquatic communities in an area will affect the fauna that are present and use the area. This section addresses the fauna likely to be found in the project study area. Terrestrial Fauna Fauna associated with the communities in the project area includes Carolina anole* (Anolis carolinensis), spring peeper (Hyla crucifer), gray squirrel (Sciurus carolinensis), opossum (Didelphis virginiana) and raccoon (Procyon lotor). White-tailed deer (Odocoileus virginianus) will use these forest communities for cover and will forage on twigs and leaves as well as mast. Avian species utilizing these areas include the prothonotary warbler (Protonotaria citrea), red-eyed vireo (Vireo olivaceus), Eastern bluebird* (Sialla stalls), yellow-rumped warbler (Dendroica coronata), yellow-bellied sapsucker (Sphyrapicus varius), red-bellied woodpecker (Melanerpes carolinus), and turkey vulture* (Cathartes aura). Aquatic Fauna Fauna associated with the aquatic community includes various invertebrate and vertebrate species. Prey fish including mosquitofish* (Gambusia affinis) provide foraging opportunities for pumpkinseed sunfish* (Lepomis gibbosus), pirate perch* (Aphredoderus sayanus) and chain pickerel (Esox niger). Invertebrates that are present include crayfish (family Cambaridae), nymphal stages of dragonflies* and damselflies* (Order Odonata), whirligig beetles* (family Gyrinidae) and shrimp* (Palaemonetes spp.). The southern dusky salamander (Desmognathus auriculatus), green frog (Rana clamitans), snapping turtle (Chelydra serpentina) and brown water snake (Nerodia taxispilota) are common permanent residents in this community. Anadromous fish such as-alewife (Alosa pseudoharengus) and blueback herring (A. aestivalis) use coastal 14 streams as spawning habitat. C. Summary of Anticipated Impacts Construction of the subject project will have various impacts on the biotic resources described. Any construction related activities in or near these resources have the potential to impact biological functions. This section quantifies and qualifies impacts to the natural resources in terms of area impacted and ecosystems affected, for each of the three project alternates. Temporary and permanent impacts are also considered here. Calculated impacts to terrestrial resources reflect the relative abundance of each community present within the study area. Project construction will result in clearing and degradation of portions of these communities. Table 2 summarizes potential quantitative losses to these biotic communities, resulting from project construction. Estimated impacts for each alternate are derived using the entire proposed right of way width. Usually, project construction does not require the entire right of way; therefore, actual impacts may be considerably less. Table 2.

' :1;7 .2. 82 1 9i 342 '7" It should be noted that the anticipated impacts for Alternates 1 and 2 are mainly temporary impacts from the detour during construction, whereas Alternate 3 is a permanent relocation of the road. Plant communities found within the proposed project area serve as nesting and sheltering habitat for various wildlife. Replacing Bridge NQ. 91 and its associated improvements will reduce habitat for faunal species, thereby diminishing faunal numbers. However, due to the size and scope of this project, it is anticipated that impacts to fauna will be minimal. Areas modified by construction (but not paved) will become road 15 shoulders and early successional habitat. Reduced habitat will displace some wildlife further from the roadway while attracting other wildlife by the creation of more early successional habitat. Animals temporarily displaced by construction activities will repopulate areas suitable for the species. Aquatic communities are sensitive to even small changes in their environment. Stream channelization, scouring, siltation, sedimentation and erosion from construction-related work will affect water quality and biological constituents. Although direct impacts may be temporary, environmental impacts from these construction processes may result in long term or irreversible effects. Impacts often associated with in-stream construction include increased channelization and scouring of the streambed. In-stream construction alters the stream substrate and may remove streamside vegetation at the site. Disturbances to the substrate will produce siltation, which clogs the gills and/or feeding mechanisms of benthic organisms (sessile filter-feeders and deposit-feeders), fish and amphibian species. Benthic*organisms can also be covered by excessive amounts of sediment. These organisms are slow to recover or repopulate a stream The removal of streamside vegetation and placement of fill material at the construction site alters the terrain. Alteration of the streambank enhances the likelihood of erosion and sedimentation. Revegetation stabilizes and holds the soil thus mitigating these processes. Erosion and sedimentation carry soils, toxic compounds and other materials into aquatic communities at the construction site. These processes magnify turbidity and can cause the formation of sandbars at the site and downstream, thereby altering water flow and the growth of vegetation. Streamside alterations also lead to more direct sunlight penetration and to elevations of water temperatures, which may impact many species. Anadromous fish are a valuable resource and their migration must not be adversely impacted. The Draft Stream Crossing Guidelines for Anadromous Fish Passage provides guidance to the NCDOT to ensure that replacement of existing stream crossing structures will not impede the movement of anadromous fish. These guidelines should be used in projects located in the coastal plain. The draft guidelines are given in the appendix. 4. Jurisdictional Topics This section provides descriptions, inventories and impact analysis 16 pertinent to two important issues--Waters of the United States and rare and protected species. a. Waters of the United States Surface waters and wetlands fall under the broad category of "Waters of the United States," as defined in Section 33 of the Code of Federal Register (CFR) Part 328.3. Wetlands, defined in 33 CFR 328.3, are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted to life in saturated conditions. Any action that proposes to place fill into these areas falls under the jurisdiction of the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean Water Act (33 U.S.C. 1344). Characteristics of Wetlands and Surface Waters Potential wetland communities were investigated pursuant to the 1987 "Corps of Engineers Wetland Delineation Manual". The three parameter approach is used, where hydric soils, hydrophytic vegetation and prescribed hydrologic characteristics must all be present for an area to be considered a wetland. Two types of wetlands are present within the project area, and are associated with the alluvial forest. The wetlands can be described as palustrine forested broad-leaved deciduous/ needle-leaved evergreen seasonally flooded (PF01/4C, Cowardin, et al), and palustrine forested broad-leaved deciduous/ needle-leaved evergreen temporarily flooded (PFO1/4A, Cowardin, et al). These wetlands can also be described as Coastal Plain Small Stream Swamp (Blackwater Subtype) and Bottomland Hardwoods, respectively (Schafale and Weakley,1990). Soils within the wetland areas have a silty texture and a Munsell color notation of 25Y 5/2. Hydrological indicators include saturated soil, the presence of oxidized rhizospheres and drift lines. Vegetation within the wetlands include green ash, red maple, Virginia willow, net-veined chain fern, climbing hempweed and climbing hydrangea. Parrot Swamp is a jurisdictional surface water under Section 404 of the Clean Water Act (33 U.S.C. 1344). Discussion of the biological, physical and water quality aspects of Parrot Swamp are presented in previous sections of this report. 17 Summary of Anticipated Impacts Table 3 summarizes anticipated impacts to wetland and surface water areas in the project area for each alternate. Anticipated impacts to these areas are determined by using the entire project right of way width; including right of way for the temporary detours. Usually, project construction does not require the entire right of way; therefore, actual wetland and surface water impacts may be considerably less. Table 3.

Permits impacts to jurisdictional surface waters are anticipated. The subject project is located within a county that is under the jurisdiction of the Coastal Area Management Act (CAMA), which is administered by the Division of Coastal Management (DCM). The DCM is the lead permitting agency for projects located within its jurisdiction. The DCM will not issue a CAMA Major Development Permit unless NCDOT receives a Stormwater Management Certification from the Division of Water Quality (DWQ). CAMA directs the Coastal Resources Commission (CRC) to identify and designate Areas of Environmental Concern (AEC's) in which 18 uncontrolled development might cause irreversible damage to property, public health, and the natural environment. CAMA necessitates a permit if the project meets all of the following conditions: - it is located in one of the 20 counties covered by LAMA; - it is in or affects an AEC designated by CRC; - it is considered "development" under the terms of the Act, and; - it does not qualify for an exemption identified by the Act or by the CRC. This project may require a CAMA permit. The CAMA major development permit application form serves as an application for three other state permits and for permits from the Corps of Engineers (COE) required by section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. The state permits include: (1) Permit to excavate and/or fill; (2) Easement in lands covered by water, and; (3) 401 Water Quality Certification. AEC information: (1) Estuarine waters are an AEC which CAMA defines as all the waters of the Atlantic Ocean within the boundaries of North Carolina and all the waters of the bays, sounds, rivers and tributaries there to seaward of the dividing line between coastal fishing waters and inland fishing waters. This definition of estuarine waters was also set forth in an agreement adopted by the Wildlife Resources Commission (WRC) and the Department of Natural Resources and Community Development. (2) A Public Trust AEC includes all waters and submerged lands in the coastal region where the public has the rights of use and/or ownership, including rights of navigation and recreation. This AEC also covers all lands under these waterways and the submerged minerals and biological resources that these submerged lands contain. (3) A Coastal Wetland AEC is defined as any marsh subject to occasional flooding by tides (including wind tides). Tidal waters may reach the marsh by either natural or artificial watercourses. Coastal Wetland AEC's, by definition, must contain certain plant species listed in the CAMA regulations. (4) An Estuarine Shoreline AEC includes all shorelines within 23.0 m (75.0 ft) landward of the mean high water level, or normal water level, of the estuarine waters. 19 A Section 404 Nationwide Permit 23 is likely to be applicable for all impacts to Waters of the United States from the proposed project. This permit authorizes activities undertaken, assisted, authorized, regulated, funded or financed in whole, or part, by another Federal agency or department where that agency or department has determined that pursuant to the council on environmental quality regulation for implementing the procedural provisions of the National Environmental Policy Act; (1) that the activity, work, or discharge is categorically excluded from environmental documentation because it is included within a category of actions which neither individually nor cumulatively have a significant effect on the human environment, and; (2) that the office of the Chief of Engineers has been furnished notice of the agency' or department's application for the categorical exclusion and concurs with that determination. A North Carolina DWQ Section 401 Water Quality General Certification is required prior to the issuance of the Section 404 permit. Section 401 Certification allows surface waters to be temporarily impacted for the duration of the construction or other land manipulations. ag tion Miti The COE has adopted, through the Council on Environmental Quality (CEQ), a wetland mitigation policy which embraces the concept of "no net loss of wetlands" and sequencing. The purpose of this policy is to restore and maintain the chemical, biological and physical integrity of Waters of the United States, specifically wetlands. Mitigation of wetland impacts has been defined by the CEQ to include: avoiding impacts (to wetlands), minimizing impacts, rectifying impacts, reducing impacts over time and compensating for impacts (40 CFR 1508.20). Each of these three aspects (avoidance, minimization and compensatory mitigation) must be considered sequentially. Avoidance Avoidance mitigation examines all appropriate and practicable possibilities of averting impacts to Waters of the United States. A 1990 Memorandum of Agreement (MOA) between the Environmental Protection Agency (EPA) and the COE states that in determining "appropriate and practicable" measures to offset unavoidable impacts, 20 such measures should be appropriate to the scope and degree of those impacts and practicable in terms of cost, existing technology and logistics in light of overall project purposes. Minimization Minimization includes the examination of appropriate and practicable steps to reduce the adverse impacts to Waters of the United States. Implementation of these steps will be required through project modifications and permit conditions. Minimization typically focuses on decreasing the footprint of the proposed project through the reduction of median widths, right of way widths, fill slopes and/or road shoulder widths. Other practical mechanisms to minimize impacts to Waters of the United States crossed by the proposed project include: strict enforcement of sedimentation control BMP's for the protection of surface waters during the entire life of the project; reduction of clearing and grubbing activity; reduction/ elimination of direct discharge into streams; reduction of runoff velocity; re-establishment of vegetation on exposed areas, judicious pesticide and herbicide usage; minimization of "in-stream" activity; and litter/ debris control. Compensatory Mitigation Compensatory mitigation is not normally considered until anticipated impacts to Waters of the United States have been avoided and minimized to the maximum extent possible. It is recognized that "no net loss of wetlands" functions and values may not be achieved in each and every permit action. Appropriate and practicable compensatory mitigation is required for unavoidable adverse impacts that remain after all appropriate and practicable minimization has been required. Compensatory actions often include restoration, creation and enhancement of Waters of the United States. Such actions should be undertaken in areas adjacent to or contiguous to the discharge site. Compensatory mitigation is not usually necessary with a Nationwide Permit # 23. b. Rare and Protected Species Some populations of fauna and flora have been in, or are in, the process of decline either due to natural forces or their inability to coexist with human activities. Federal law (under the provisions of the Endangered Species Act of 1973, as amended) requires that any action likely to adversely affect a species classified as federally protected be subject to review by the Fish and Wildlife Service (FWS). Other species 21 may receive additional protection under separate state laws. Federally-Protected Species Plants and animals with federal classifications of Endangered (E), Threatened (T), Proposed Endangered (PE) and Proposed Threatened (PT) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act (ESA) of 1973, as amended. As of 28 February 2000, the FWS lists the following federally-protected species for Onslow County (see Table 4). A brief description of each species' characteristics and habitat follows. Table 4.

"T" denotes Threatened la species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range). "T(S/ A)" denotes Threatened due to similarity of appearance (a species that is threatened due to similarity of appearance with other rare species and is listed for its protection. These species are not biologically endangered or threatened and are not subject to Section 7 consultation.) Alligator mississippiensis (American alligator) Threatened due to Similarity Animal Family: Crocodylidae of Appearance Date Listed: 6/4/87 The American alligator is a large roughbacked reptile with a broad rounded snout. Most adults range in size from 6 to 12 feet. Habitat for the alligator includes river systems, canals, lakes, swamps, bayous, and coastal marshes. The alligator will eat almost anything of suitable size including mammals, reptiles, amphibians, birds, fish, and crustaceans. Species that have the federal classification of Threatened due to Similarity of Appearance are not biologically endangered or threatened 22 and do not receive protection under Section 7. However, due to its similarity of appearance to other protected crocodilians, federal regulations, such as hide tagging requirements, are maintained on the commercial trade to help control illegal taking of the protected species. The NHP database of rare species and unique habitats contains no record of American alligator within the study area. Caretta caretta (loggerhead turtle) Threatened Animal Family: Cheloniidae Date Listed: 7/ 28/ 78 Loggerhead turtles can be distinguished from other sea turtles by its unique reddish-brown color. The loggerhead is characterized by a large head and blunt jaws. Additionally, they have 5 or more costal plates with the first touching the nuchal and 3 to 4 bridge scutes. The loggerhead nests on suitable beaches from Ocracoke Inlet, North Carolina through Florida and on a small scale off of the Gulf States. There are also major nesting grounds on the eastern coast of Australia. It lives worldwide in temperate to subtropical waters. Loggerheads nest nocturnally between May and September on isolated beaches that are characterized by fine grained sediments. It is mainly carnivorous, feeding on small marine animals. BIOLOGICAL CONCLUSION NO EFFECT Nesting beaches are not present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of loggerhead turtles in the project vicinity. Therefore, project construction will not affect the loggerhead turtle. Charadrius melodus (piping plover) Threatened Animal Family: Charadriidae Date Listed: 12/11/85 The piping plover is a small migratory shorebird that resembles a sandpiper. It can be identified by the orange legs and black band around the base of its neck. During the winter the plover loses its black band, its legs fade to pale yellow, and the bill fades to black. Breeding birds are characterized by white underparts, a single black breastband, and a black bar across the forehead. 23 The piping plover breeds along the east coast. In North Carolina, nesting occurs in flat areas with fine sand and mixtures of shells and pebbles. They nest most commonly where there is little or no vegetation, but some may nest in stands of beachgrass. The nest is a shallow depression in the sand that is usually lined with shells and pebbles. The piping plover is very sensitive to human disturbances. The presence of people can cause the plover to abandon its nest and quit feeding. BIOLOGICAL CONCLUSION NO EFFECT No suitable habitat in the form of beaches with fine sand and mixtures of sand and pebbles is present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of piping plover in the project vicinity. This species is known only from outer barrier beaches. Therefore, project construction will not affect the piping plover. Chelonia mydas (green sea turtle) Threatened Animal Family: Cheloniidae Date Listed: 7/ 28/ 78 The distinguishing factors found in the green sea turtle are the single clawed flippers and a single pair of elongated scales between the eyes. This sea turtle has a small head and a strong, serrate, lower jaw. The green sea turtle is found in temperate and tropical oceans and seas. Nesting in North America is limited to small communities on the east coast of Florida, requiring beaches with minimal disturbances and a sloping platform for nesting (they do not nest in NC). The green sea turtle can be found in shallow waters. They are attracted to lagoons, reefs, bays, mangrove swamps and inlets where an abundance of marine grasses, the principal food source of the green turtle, can be found. BIOLOGICAL CONCLUSION NO EFFECT Nesting beaches are not present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of green turtles in the project vicinity. Therefore, project construction will not affect the green turtle. 24 Dermochelys coriacea (leatherback sea turtle) Endangered Animal Family: Dermochelydae Date Listed: 6/2/72 The leatherback sea turtle is the largest of the marine turtles. Unlike other marine turtles, the leatherback has a shell composed of tough leathery skin. The carapace has 7 longitudinal ridges and the plastron has 5 ridges. The leatherback is black to dark brown in color and may have white blotches on the head and limbs. Leatherbacks are distributed world-wide in tropical waters of the Atlantic, Pacific, and Indian oceans. Leatherbacks prefer deep waters and are often found near the edge of the continental shelf. In northern waters they are reported to enter bays, estuaries, and other inland bodies of water. Leatherback nesting requirements are very specific, they need sandy beaches backed with vegetation in the proximity of deep water and generally with rough seas. Beaches with a suitable slope and a suitable depth of coarse dry sand are necessary for the leatherback to nest. Major nesting areas occur in tropical regions and the only nesting population in the United States is found in Martin County, Florida. Leatherback nesting occurs from April to August. Artificial light has been shown to cause hatchlings to divert away from the sea. Leatherbacks feed mainly on jellyfish. They are also known to feed on sea urchins, crustaceans, fish, mollusks, tunicates, and floating seaweed. BIOLOGICAL CONCLUSION NO EFFECT Nesting beaches are not present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of leatherback turtles in the project vicinity. Therefore, project construction will not affect the leatherback turtle. Felis concolor cougar (eastern cougar) Endangered Animal Family: Felidae Date Listed: 6/4/73 Cougars are tawny colored with the exception of the muzzle, the backs of the ears, and the tip of the tail, which are black. In North Carolina the cougar is thought to occur in only a few scattered areas, possibly 25 including coastal swamps and the southern Appalachian Mountains. The eastern cougar is found in large remote wilderness areas where there is an abundance of their primary food source, white-tailed deer. A cougar will usually occupy a range of 25.0 miles and they are most active at night. BIOLOGICAL CONCLUSION NO EFFECT Habitat in the form of large remote wilderness does not exist within the project area. The project area is located close to the moderately developed areas of Swansboro and Jacksonville, and it is not likely that cougars would use this area. The N.C. Natural Heritage Program database of rare species and unique habitats was reviewed and revealed no records of eastern cougars in the project vicinity. Therefore, project construction will not affect the eastern cougar. Picoides borealis (red-cockaded woodpecker) Endangered Animal Family: Picidae Date Listed: 10/13/70 The adult red-cockaded woodpecker (RCW) has plumage that is entirely black and white except for small red streaks on the sides of the nape in the male. The back of the RCW is black and white with horizontal stripes. The breast and underside of this woodpecker are white with streaked flanks. The RCW has a large white cheek patch surrounded by the black cap, nape, and throat. The RCW uses open old growth stands of southern pines, particularly longleaf pine (Pinus palustris), for foraging and nesting habitat. A forested stand must contain at least 50% pine, lack a thick understory, and be contiguous with other stands to be appropriate habitat for the RCW. These birds nest exclusively in trees that are > 60 years old and are contiguous with pine stands at least 30 years of age. The foraging range of the RCW is up to 200.0 hectares (500.0 acres). This acreage must be contiguous with suitable nesting sites. These woodpeckers nest exclusively in living pine trees and usually in trees that are infected with the fungus that causes red-heart disease. Cavities are located in colonies from 3.6-30.3 m (12-100 ft) above the ground and average 9.1-15.7 m (30-50 ft) high. They can be identified by a large encrustation of running sap that surrounds the tree. The RCW lays its eggs in April, May, and June; the eggs hatch approximately 38 days later. BIOLOGICAL CONCLUSION NO EFFECT 26 Nesting and foraging habitat requirements considered necessary for the RCW are not present within the project vicinity. There are no old growth stands of southern pine in vicinity of the project. Additionally, forested areas in the project vicinity consist of mixed pine/hardwood forests, which are less than fifty percent pine and generally have a dense understory of hardwood saplings and shrubs. The NC Natural Heritage Program database of rare species and unique habitats has no record for the presence of the RCW within the project vicinity. Therefore, no impact to the red-cockaded woodpecker will result from project construction. Amaranthus pumilus (seabeach amaranth) Threatened Plant Family: Amaranthaceae Date Listed: 4/ 7/ 93 Flowers Present: June to frost Seabeach amaranth is an annual legume that grows in clumps containing 5 to 20 branches and which are often over a foot across. The trailing stems are fleshy and reddish-pink or reddish in color. Seabeach amaranth has thick, fleshy leaves that are small, ovate-spatulate, emarginate and rounded. The leaves are usually spinach green in color, cluster towards the end of a stem, and have winged petioles. Flowers grow in axillary fascicles and the legume has smooth, indehsicent fruits. Seeds are glossy black. Both fruits and flowers are relatively inconspicuous and borne along the stem. Seabeach amaranth is endemic to the Atlantic Coastal Plain beaches. Habitat for seabeach amaranth is found on barrier island beaches functioning in a relatively dynamic and natural manner. Seabeach amaranth grows well in overwash flats at the accreting ends of islands and the lower foredunes and upper strands of noneroding beaches. Temporary populations often form in blowouts, sound-side beaches, dredge spoil, and beach replenishment. ' This species is very intolerant to competition and is not usually found in association with other species. Threats to seabeach amaranth include beach stabilization projects, all terrain vehicles (ATV's), herbivory by insects and animals, beach grooming, and beach erosion. BIOLOGICAL CONCLUSION NO EFFECT Suitable habitat in the form of barrier island beaches functioning in a relatively dynamic and natural manner does not exist within the project area. The project area is located in the upper reaches of the estuary and does not contain beach habitat. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no 27 records of seabeach amaranth in the project vicinity. Therefore, project construction will not affect the seabeach amaranth. Lysimachia asperulaefolia (rough-leaved loosestrife) Endangered Plant Family: Primulaceae Federally Listed: 6/ 12/ 87 Flowers Present: June Rough-leaved loosestrife is a perennial herb having slender stems and whorled leaves. This herb has showy yellow flowers, usually occurring in threes or fours. Fruits are present from July through October. Rough-leaved loosestrife is endemic to the coastal plain and sandhills of North and South Carolina. This species occurs in the ecotones or edges between longleaf pine uplands and pond pine pocosins (areas of dense shrub and vine growth usually on a wet, peaty, poorly drained soil), on moist to seasonally saturated sands and on shallow organic soils overlaying sand. It has also been found to occur on deep peat in the low . shrub community of large Carolina bays (shallow, elliptical, poorly drained depressions of unknown origins). The areas it occurs in are fire maintained. Rough-leaved loosestrife rarely occurs in association with hardwood stands and prefers acidic soils. BIOLOGICL CONCLUSION NO EFFECT Rough-leaved loosestrife habitat in the form of ecotones or edges between longleaf pine uplands and pond pine pocosins is not present in the project study area. The study area contains bottomland hardwoods and small stream swamp forest. The N.C. Natural Heritage Program data base, of rare species and unique habitats was reviewed and revealed no records of rough-leaved loosestrife in the project vicinity. During a second site visit on 22 June 1999, areas of suitable habitat within the project study area were surveyed by NCDOT biologists Dale Suiter and Jim Hauser. A plant by plant survey was unsuccessful. No rough-leaved loosestrife plants were located. The NCNHP records were checked via ArcView that was last updated in January 1999. At that time, no populations of rough-leaved loosestrife were known from the project study area. This project will not affect rough-leaved loosestrife. Thalictrum cooleyi (Cooley's meadowrue) Endangered Plant Family: Ranunculaceae Federally Listed: 2/7/89 Flowers Present: late June July (best mid July) 28 Cooley's meadowrue is a rhizomatous perennial plant with stems that grow to one meter in length. Stems are usually erect in direct sunlight but are lax and may lean on other plants or trail along the ground in shady areas. Leaves are usually narrowly lanceolate and unlobed, some two or three lobed leaves can be seen. The flowers lack petals. Fruits mature from August to September. Cooley's meadowrue occurs in moist to wet bogs, savannas and savanna-like openings, sandy roadsides, rights-of-ways, and old clearcuts. This plant is dependent on some form of disturbance to maintain its habitat. All known populations are on circumneutral, poorly drained, moderately permeable soils of the Grifton series. Cooley's meadowrue only grows well in areas with full sunlight. BIOLOGICAL CONCLUSION NO EFFECT The project area does contain open sandy roadsides that could potentially support Cooley's meadowrue. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of rough-leaved loosestrife in the project vicinity. No individuals were observed during the initial site visit. During a second site visit on 22 June 1999, areas of suitable habitat within the project study area were surveyed by NCDOT biologists Dale Suiter and Jim Hauser. A plant by plant survey was unsuccessful. No Cooley's meadowrue plants were located. The NCNHP records were checked via ArcView that was last updated in January 1999. At that time, no populations of Cooley's meadowrue were known from the project study area. This project will not affect Cooley's meadowrue. Federal Species of Concern and State Listed Species There are 22 Federal Species of Concern (FSC) listed for Onslow County. Federal Species of Concern are not afforded federal protection under the ESA and are not subject to any of its provisions, including Section 7, until they are formally, proposed or listed As Threatened or Endangered. Federal Species of Concern are defined as those species that may or may not be listed in the future. These species were formerly candidate species, or species under consideration for listing for which there was insufficient information to support a listing of Endangered, Threatened, Proposed Endangered and Proposed Threatened. Organisms 29 which, are listed as Endangered (E), Threatened (T), Significantly Rare (SR), or Special Concern (SC) by the North Carolina Natural Heritage Program (NCNHP) list of rare plant and animal species are afforded state protection under the State Endangered Species Act and the North Carolina Plant Protection and Conservation Act of 1979. Table 5 lists-Federal Species of Concern, the species state status (if afforded state protection) and the presence of suitable habitat for each species in the study area.

CONCLUSION On the basis of the above discussion, it is concluded that no substantial adverse environmental effects will result from the implementation of the project. The proposed project is considered to be a "categorical exclusion" as defined by the Federal Highway Administrations environmental guidelines (23 CFR 771.117). 31 FIGURES ? }:.a ?r: ;?`? ?? ? ? t ..,. ?,. -, h? ,. ` r `, '?£`` . ? ? ??..., k?

We reported our available information on historic architectural and archaeological surveys and resources along with our recommendations. NCDOT provided project area photographs and aerial photographs at the meeting. Based upon our review of the photographs and the information discussed at the meeting, we offer our preliminary comments regarding this project. In terms of historic architectural resources, we are aware of no historic structures located within the area of potential effect. We recommend that no historic architectural survey be conducted for this project. There are no known archaeological sites within the proposed project area. Based on our present knowledge of the area, it is unlikely that any archaeological resources which may be eligible for inclusion in the National Register of Historic Places will be affected by the project construction. We, therefore, recommend that no archaeological investigation be conducted in connection with this project. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which indicates how NCDOT addressed our comments. The. above comments are made pursuant to Section 106 of the National Historic Preservation Act of 1966 and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codified at 36 CFR Part 800. non Nicholas L.

Addendum to Categorical Exclusion Green Sheet August 2001 Page 1 of 1 Onslow County Bridge No. 91 on SR 1509 Over Parrot Swamp Federal Project MABRZ-1509 (4) State Project 8.2260901 TIP No. B-3358 I. BACKGROUND A Categorical Exclusion for the subject project was approved on April 27, 2000. A vicinity map for this project is shown in Figure 1. The original recommended alternative (Alternate 3) was to replace Bridge No. 91 on new alignment to the east of the existing bridge with a bridge approximately 18 meters (60 feet) in length. The U. S. Army Corps of Engineers preferred a temporary on-site detour, rather than a permanent relocation of the bridge. The temporary on-site detours in Alternates 1 and 2 are the same length, have the same design speed (100 km/h [60 mph]), and are in the same location as a permanent relocation of the road. To minimize impacts, a new alternative was studied with a shorter temporary detour. This alternative, Alternate 4, is now the recommended alternative. Alternate 4 is shown in Figure 2. Changes to the proposed project are described in this Addendum to Categorical Exclusion. All other information presented in the Categorical Exclusion for this project is valid. II. DISCUSSION Three alternatives were considered in the Categorical Exclusion. A fourth alternative was studied at the request of the U. S. Army Corps of Engineers. All four alternatives are listed below. Alternate 1 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. The on-site detour will be approximately 420 meters (1380 feet) in length. Two residences will be relocated as a result of construction of this alternative. The design speeds of the temporary detour and the proposed roadway will be 100 km/h (60 mph). Alternate 2 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour east of the existing bridge during construction. The on-site detour will be approximately 420 meters (1380 feet) in length. One business will be relocated as a result of construction of this alternative. The design speeds of the temporary detour and the proposed roadway will be 100 km/h (60 mph). Alternate 3 (Recommended in the CE) . Replace Bridge No. 91 on new alignment to the east of the existing bridge with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on the existing bridge during construction. Two residences will be relocated as a result of construction of this alternative. The design speed of the proposed roadway will be 100 km/h (60 mph). Alternate 4 (New Recommended) Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. The on-site detour will be approximately 213 meters (700 feet) in length. Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. No residences or businesses will be relocated as a result of construction of this alternative. The design speed of the temporary detour will be 70 km/h (45 mph). The design speed of the proposed roadway will be 100 km/h (60 mph). Alternate 4 is shown in Figure 2. Estimated costs of the alternatives studied are shown in Table 1. Table 1.

Calculated impacts to biotic resources reflect the relative abundance of each community present within the study area. Project construction will result in clearing and degradation of portions of these communities. Estimated impacts are derived using the project plan sheets provided by NCDOT's Roadway Design Unit. Table 2 summarizes potential quantitative losses due to project construction for each alternate studied. The paved roadway width has been excluded from the impact calculations. Wetland impacts occurring due to the construction of the detour bridge may be considered permanent impacts due to the design of the temporary bridge. Therefore, all impacts occurring from project construction will be considered permanent impacts. All wetland areas impacted by the temporary detour bridge will be restored to their original elevation prior to project construction and will be replanted with the appropriate wetland vegetation.

Estimated linear impacts are derived using the cut and fill lines for the detour and replacement bridges located on the design plans. Anticipated impacts to Parrot Swamp will be approximately 120.0 ft (36.6 m) for Alternate 4. However, Parrot Swamp will be bridged, therefore, actual surface water impacts will be considerably less. Other environmental consequences of the alternatives are considered to be approximately equal and are limited in scope. These impacts are accurately described in the Categorical Exclusion. III. RECOMMENDATION Bridge No. 91 will be replaced as recommended in Alternate 4 in its existing location with a new structure approximately 18 meters (60 feet) in length. The clear roadway width of the bridge will be 12 meters (40 feet) to accommodate two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) rail offsets. The roadway approaching the bridge will consist of two 3.6-meter (12-foot) lanes with 2.4-meter (84oot) grassed shoulders. The new bridge will be at approximately the same elevation as the existing bridge. Based on preliminary design, the design speed of the proposed roadway will be 100 km/h (60 mph). Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. The length of the temporary detour will be approximately 213 meters (700 feet). The design speed of the temporary detour will be 70 km/h (45 mph). 4 FIGURES NORTH CAROLINA DEPARTMENT OF TRANSPORTATION ( ,f DIVISION OF HIGHWAYS PROJECT DEVELOPMENT AND ENVIRONMENTAL ANALYSIS BRANCH l .lJ h n N`L ??

C?F Raleigh, North Carolina 27699-1548 %p°rv'4A`t .Ph 7A L No Dear Mr. Gilmore: Our Bridge Staff has reviewed your plans and specifications, dated January 9, 2002, for the replacement of a timber bridge in Onslow County, North Carolina. The waterway involved in this project is considered a navigable waterway of the United States for Bridge Administration purposes. It also meets the criteria for advance approval waterways set forth in Title 33, Code of Federal Regulations, Section 115.70, at the bridge site. Advance approval waterways are those that are navigable in law, but not actually navigated by other than small boats. In such cases, the Commandant of the Coast Guard has given his advance approval to the construction of bridges across such waterways. The North Carolina State project for Parrot Swamp qualifies for the Advance Approval category. Accordingly, an individual Coast Guard bridge permit will not be required for the new bridge across this waterway. The fact that a Coast Guard permit will not be required for this advance approval bridge, does not relieve you of the responsibility for compliance with the requirements of any other Federal, State, or local agency who may have jurisdiction over any aspect of this project. Sincerely, ANN B. DEATON Chief, Bridge Section By direction of the Commander Fifth Coast Guard District William G. Ross, Jr., Secretary North Carolina Department of Environment and Natural Resources Gregory J.

NC Department Of Transportation 1590 Mail Service Center Raleigh, NC 27699-1590 Subject: EXEMPTION from Stormwater Management Permit Regulations Stormwater Project No. SW8 011115 Dear Mr. Fisher: b l1e?`.jr q,a.l?err..tti;; +Y? "Apl . ..a }G3Ci. The Wilmington Regional Office received a copy of your application for the project known as B-3358 Onslow County Bridge #91 Replacement. Staff of the Wilmington Regional Office have reviewed the application for the applicability of the Stormwator Management rules to the proposed activity at this project. Based on our review, you do not appear to be proposing a development activity on this site at this point in time that would be subject to the stormwater requirements as provided for in 15A NCAC 214.1000. Please be advised that tither regulations will potentially apply to your proposed activities. If your project disturbs five acres or more and has a point source discharge of stormwater runoff, then it is subject to the National Pollutant Discharge Elimination System (NPDES) stormwater discharge requirements. You are required to have an NPDES permit for stormwater discharge from projects meeting these criteria. This exemption applies only to the Coastal Stormwater Management Permit for the currently proposed activity. If at any time in the future, development of any part of this site is planned, as defined in NCAC 2H.1000, or if the proposed activities differ in any manner from what is shown on the plans on file with the Division, you must submit the project for review of the applicability of the stormwater management rules. If you have any questions concerning this matter, please do not hesitate to call me at (910) 395-3900. Sincerely, c..

Department of Environment and Natural Resources Division of Coastal Management 020670, 151-B Hwy 24 Hestron Plaza II Morehead City, NC 28557 ATTENTION: Dear' Mr. Tyndall: Mr. Ted Tyndall District Manager Subject: Onslow County, CAMA Major Development Permit Application for the replacement of Bridge No. 91 over Parrot Swamp on SR 1509, NCDOT Division 3, Federal Aid Project No. MABRZ-1509(4), State Project No. 8.2260901, TIP Project No. B-3358. Please find enclosed copies of the Categorical Exclusion (CE), an Addendum to the CE, the Coastal Area Management Act (CAMA) permit application, permit drawings, a letter from the Coast Guard, a North Carolina Division of Water Quality (DWQ) Stormwater Exemption letter, and a check for $400.00 for the application fee for the above referenced project. Bridge No. 91 will be replaced on the existing alignment with a new bridge approximately 60 feet (18.0 meters) in length and 40 feet (12.0 meters) in width. The new bridge will have two 12.0 foot (3.6 meters) travelways with 8.0 foot (2.4 meters) rail offsets. The approach roadway will consist of two 12.0-foot (3.6-meter) lanes with grassed shoulders at leapt 8.0 foot (2.4 meters) wide. During construction, traffic will be maintained on a temporary on-site detour west of the existing bridge. The length of the temporary detour will be approximately 700 feet (213.0 meters) with a temporary bridge approximately 60.0 feet (18.2 meters) in length. Impacts to wetlands associated with the replacement of Bridge No. 91 will include temporary fill and mechanized clearing due to the temporary detour. Mechanized clearing will be by Method III. Parrot Swamp is classified as SA waters by the Division of Water Quality and is designated by North Carolina Division of Marine Fisheries as a Primary Nursery Area. Therefore, NCDOT will strictly adhere to "Design Standards in Sensitive Watersheds" (15A NCAC 04B .0024) (High Quality Water Standards) throughout design and construction of this project. 7 Temporary Bridge Information: A temporary bridge will be located west of the existing bridge. The temporary bridge will consist a concrete deck with Class II riprap on top of filter fabric. The resulting temporary fill in wetlands associated with the temporary detour bridge is 017 acre (0.07 hectare) and approximately 0.06 acre (0.02 hectare) in mechanized clearing. Restoration Plan: Upon completion of the new bridge, the temporary bridge will be removed. The approach fill will be removed to natural grade (Elevations and contours in the vicinity are available from field survey notes). The area will be planted with appropriate native wetland species. Minimization: The original alternate chosen involved placing the temporary detour bridge on the eastern side of SR 1509. After evaluation by the NCDOT Natural Systems Staff, it was concluded that the wetlands on the east are comparatively higher quality than the wetlands on the western side of SR 1509. Therefore, the decision was made to move the temporary detour to the west side in order to decrease the amount of higher quality wetlands impacted. Detour fill slopes have been reduced to 2:1 to reduce roadway fill. Mitigation: All project impacts are considered permanent since compression of muck soils may have permanent negative environmental consequences. A total of 0.23 acre (0.09 ha) of riverine wetland impacts will occur on this project. NCDOT proposes to debit the Clayhill Farms mitigation bank. This site is located northeast of Jacksonville in Jones County. Schedule: The project schedule calls for an October 15, 2002 let date with an availability date approximately six weeks after. It is expected that the contractor will choose to start construction of the temporary detour bridge shortly after the availability date. The temporary bridge will be removed within 90 days upon completion of the project. Disposal: After the temporary bridge is no longer needed, the contractor will use roadway building equipment to remove the concrete deck and riprap. All temporary bridge material will become the property of the contractor. The contractor will be required to submit a reclamation plan for removal and disposal of all material off-site. Bridge Demolition: Bridge No. 91 contains two main spans totaling 36 feet (11.0 meters) and is 26 feet (7.9 meters) wide. The bridge has a reinforced concrete floor on timber joists and the substructure is reinforced concrete caps on timber piles. Both the bridge rail and substructure will be removed without dropping components into Waters of the United States. There is potential for components of the deck to be dropped into Waters of the United States during construction. The resulting temporary fill associated with the concrete deck is approximately 10.0 yd3 (7.6 m) . However, it is anticipated that the bridge will be removed without dropping components into the river. During construction, Best Management Practices for Bridge Demolition and Removal will be followed. Threatened and Endangered Species: As of February 26, 2001, the U.S. Fish and Wildlife Service (USFWS) lists ten federally protected species for Onslow County. On January 23, 2002 the USFWS determined the endangered status for golden sedge (Carex lutea); therefore, golden sedge was added to the federally protected species list for Onslow County. The NCDOT evaluation of the original ten species in November of 1998 and June of 1999 resulted in Biological Conclusions of "No Effect" for all of these species. A survey has not been conducted for the golden sedge and additional surveys will be conducted for rough-leaved loosestrife (Lysimachia asperulaefolia) and Cooley's meadowrue (Thalictrum cooleyi). Therefore, surveys for goldensedge, rough-leaved loosestrife, and Cooley's meadowrue will be conducted prior to project construction. The results of these surveys will be forwarded to the resource agencies as soon as they are available. A review of the NC Natural Heritage Program database of rare species and unique habitats on January 7, 2002 revealed that no known occurrences of any federally protected species occur within one mile of the project area. NCDOT requests that the proposed work be authorized under a Coastal Area Management Act Major Development Permit. A check for $400.00 for the application fee is enclosed. Copies of the green cards will be forwarded as soon as they are available. By copy of this letter, we are also requesting issuance of a United States Army Corps of Engineers NWP 23 and a 401 Water Quality Certification from the North Carolina Division of Water Quality. If you have any questions or need additional information, please contact Ms. Lynn Smith at (919) 733-7844, extension 286. Sincerely, William D.

P Raleigh, North Carolina 27699-154 At Dear Mr. Gilmore: Our Bridge Staff has reviewed your plans and specifications, dated January 9, 2002, for the replacement of a timber bridge in Onslow County, North Carolina. The waterway involved in this project is considered a navigable waterway of the United States for Bridge Administration purposes. It also meets the criteria for advance approval waterways set forth in Title 33, Code of Federal Regulations, Section 115.70, at the bridge site. Advance approval waterways are those that are navigable in law, but not actually navigated by other than small boats. In such cases, the Commandant of the Coast Guard has given his advance approval to the construction of bridges. across such waterways. The North Carolina State project for Parrot Swamp qualifies for the Advance Approval category. Accordingly, an individual Coast Guard bridge permit will not be required for the new bridge across this waterway. The fact that a Coast Guard permit will not be required for this advance approval bridge, does not relieve you of the responsibility for compliance with the requirements of any other Federal, State, or local agency who may have jurisdiction over any aspect of this project.

Staff of the Wilmington Regional Office have reviewed the application for the applicability of the Stormwater Management rules to the proposed activity at this project. Based on our review, you do not appear to be proposing a development activity on this site at this point in time that would be subject to the stormwater requirements as provided for in 15A NCAC 2H.1000. Please be advised that other regulations will potentially apply to your proposed activities. If your project disturbs five acres or more and has a point source discharge of stormwater runoff, then it is subject to the National Pollutant Discharge Elimination System (NPDES) stormwater discharge requirements. You are required to have an NPDES permit for stormwater discharge from projects meeting these criteria. This exemption applies only to the Coastal Stormwater Management Permit for the currently proposed activity. If at any time in the future, development of any part of this site is planned, as defined in NCAC 2H.1000, or if the proposed activities differ in any manner from what is shown on the plans on file with the Division, you must submit the project for review of the applicability of the stormwatter management rules. If you have any questions concerning this matter, please do not hesitate to call me at (910) 395-3900.

Categorical Exclusion April 2000 Onslow County Bridge No. 91 on SR 1509 Over Parrot Swamp Federal Project MABRZ-1509 (4) State Project 8.2260901 TIP No. B-3358 The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge No. 91 in Onslow County (see Figure 1). This bridge carries SR 1509 over Parrot Swamp. This project is included in NCDOT's 2000-2006 Transportation Improvement Program (TIP) as a bridge replacement project. NCDOT and the Federal Highway Administration (FHWA) classify this project as a Categorical Exclusion. No substantial environmental impacts are expected. I. SUMMARY OF RECOMMENDATIONS Bridge No. 91 will be replaced as recommended in Alternate 3 with a bridge on new alignment approximately 18 meters (60 feet) east of the existing structure (see Figure 2). The new structure will be a approximately 18 meters (60 feet) in length. The clear roadway width of the bridge will be 12 meters (40 feet) to accommodate two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) rail offsets. The roadway approaching the bridge will consist of two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) grassed shoulders. The new bridge will be at approximately the same elevation as the existing bridge. Based on preliminary design, the design 'speed will be 100 km/h (60 mph). Traffic will be detoured on the existing alignment during construction. . - The estimated cost of the project is $1,018,000 including $950,000 in construction costs and $68,000 in right of way costs. The estimated cost shown in the 2000-2006 TIP is $325,000. The current estimated cost of the proposed improvements exceeds the TIP funding by $693,000. Right of way acquisition for the project is scheduled to begin in fiscal year 2001 and construction is scheduled to begin in fiscal year 2002. H. ANTICIPATED DESIGN EXCEPTIONS There are no design exceptions currently associated with this project. A final determination on design exceptions will be made during the design phase for the project. III. EXISTING CONDITIONS SR 1509 is classified as a Rural Minor Collector in the Statewide Functional Classification System. It is located approximately 5.6 kilometers (3.5 miles) south of Swansboro, N. C. The posted speed limit in the vicinity of the bridge is 90 km/h (55 mph). There were four reported accidents in the vicinity of the bridge during the three-year period from August 1, 1994, to July 31, 1997. The existing bridge was built in 1959. The bridge includes two main spans totaling 11.0 meters (36 feet) in length and is 7.9 meters (26 feet) wide. It has a reinforced concrete floor on timber joists and the substructure has reinforced concrete caps on timber piles. The bridge carries two lanes of traffic and has a 7.2-meter (24-foot) roadway width. The approach roadway is 6.1 meter (20 feet) wide with grass shoulders. It is approximately 3.6 meters (12 feet) above the streambed. Both the bridge rail and substructure will be removed without dropping them into Waters of the United States. There is potential for components of the deck to be dropped into Waters of the United States during construction. The resulting temporary fill associated with the concrete deck is approximately 7.6 m3(10 yd3). According to Bridge Maintenance Unit records, the sufficiency rating of the bridge is 46.5 out of a possible 100. Presently the bridge is posted with weight restrictions of 18 tons for single vehicles and 25 tons for truck-tractor semi-trailers. The Traffic Forecasting Unit has indicated that near Bridge No. 91, SR 1509 carries 6,200 vehicles per day in the year 2000. This figure is expected to increase to 12,100 vehicles per day by the year 2025. These traffic figures include 3 % dual tired vehicles [DUAL], and 1 % truck-tractor semi-trailers [TTST]. The design hourly volume [DHV] is 10%. The Onslow County School Bus Transportation Coordinator indicated that 25 school buses each cross this bridge as many as 6 times per day during the school year. IV. STUDIED ALTERNATES A. Alternative 1 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. Two residences will be relocated as a 2 result of construction of this alternate. B. Alternative 2 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour east of the existing bridge during construction. One business will be relocated as a result of construction of this alternate. C. Alternative 3 (Recommended) Replace Bridge No. 91 on new alignment to the east of the existing bridge with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on the existing bridge during construction. Two residences will be relocated as a result of construction of this alternate. D. Other Alternatives The "do-nothing" alternative is not practical; requiring the eventual closing of the road as the existing bridge completely deteriorates. Rehabilitation of the existing deteriorating bridge is neither practical nor economical. An alternative with an off-site detour is not reasonable. The shortest detour route is more than 19 kilometers (12 miles) in length (see Figure 1). This would generate a much greater cost to the average road user during the course of construction than an on-site detour. An off-site detour is also undesirable due to the resulting community impacts. Two schools have recently been constructed in the area. As mentioned above, 25 school buses each cross the bridge as many as 6 times per day during the school year. Closing the bridge during construction would cause substantial delays for these buses and would be an obstacle to school bus operations. 3 V.

RECOMMENDED IMPROVEMENTS Bridge No. 91 will be replaced as recommended in Alternate 3 with a bridge on new alignment approximately 18 meters (60 feet) east of the existing structure (see Figure 2). The new structure will be a approximately 18 meters (60 feet) in length. The clear roadway width of the bridge will be 12 meters (40 feet) to accommodate two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) rail offsets. The roadway approaching the bridge will consist of two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) grassed shoulders. The new bridge will be at approximately the same elevation as the existing bridge. Based on preliminary design, the design speed will be 100 km/h (60 mph). Traffic will be detoured on the existing alignment during construction. Upon completion of the new bridge, the existing bridge will be removed. The existing approach fill will be removed to natural grade and the area will be planted with native grasses and/or tree species as appropriate. Alternate 3 is recommended because it has the lowest cost of the alternates considered. Also, there is a relatively small difference in environmental impacts between the alternatives. The Division concurs with the recommendation. 4 VII. ENVIRONMENTAL EFFECTS A. General This project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. This project is considered to be a "Categorical Exclusion" due to its limited scope and insignificant environmental consequences. This bridge replacement will not have a substantial adverse effect on the quality of the human or natural environment by implementing the project commitments listed in the front of this document, and by using current NCDOT standards and specifications. The project is not in conflict with any plan, existing land use, or zoning regulation. No change in land use is expected to result from construction of this project. There are no hazardous waste impacts. No adverse effect on families or communities is anticipated. Right-of-way acquisition will be limited. Two residences will be relocated as a result of construction of the project. No adverse effect on public facilities or services is expected. The project is not expected to adversely affect social, economic, or religious opportunities in the area. There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of national, state, or local significance in the vicinity of the project. The proposed bridge replacement project will not raise the existing flood levels or have any significant adverse effect on the existing floodplain. Utility conflicts will be medium for the project. There is a water line along the east side of SR 1509. There are aerial telephone and power lines along the west side of SR 1509. There is a fiber-optic cable on the west side of SR 1509, which is above ground across the swamp. 5 B. Air And Noise This project is an air quality "neutral" project, so it is not required to be included in the regional emissions analysis and a project level CO analysis is not required. If vegetation is disposed of by burning, all burning shall be done in accordance with applicable local laws and regulations of the North Carolina SIP for air quality in compliance with 15 NCAC 2D.0520. The project will not substantially increase traffic volumes. Therefore, it will not have substantial impact on noise levels. Temporary noise increases may occur during construction. C. Land Use & Farmland Effects In the vicinity of this project, Onslow County has no zoning. This project will impact no soils considered to be prime or important farmland. D. Historical Effects & Archaeological Effects The State Historic Preservation Office (SHPO) has indicated that there are no known historic architectural resources in the project area. Therefore, SHPO has recommended that no historic architectural survey be conducted for the project (see letter dated November 12,1997, in the appendix). The State Historic. Preservation Office (SHPO) has indicated that there are no known archaeological sites in the project area and no unknown sites are likely to be found. Therefore, SHPO has recommended that no archaeological investigation be conducted for the project (see letter dated November 12,1997, in the appendix). E. Natural Resources 1. Methodology Research was conducted prior to field investigations. Information sources used in this pre-field investigation of the study area include: U.S. Geological Survey (USGS) quadrangle map (Hubert), U.S. Fish and Wildlife Service (FWS) National Wetland Inventory Map (Hubert), 6 Department of Agriculture (Soil Conservation Service) soil maps (Onslow County), and NCDOT aerial photographs of project area (1:1200). Water resource information was obtained from publications of the Department of Environment and Natural Resources (DENR,1997) and from the NC Center for Geographic Information and Analysis (Environmental Sensitivity Base Map of Onslow County, 1995). Information concerning the occurrence of federal and state protected species in the study area was gathered from the Fish and Wildlife Service (FWS) list of protected species and species of concern, and the N.C. Natural Heritage Program (NHP) database of rare species and unique habitats. General field surveys were conducted along the proposed alignment by NCDOT biologists Susan Brady and Logan Williams on 2 November 1998. Plant communities and their associated wildlife were identified and recorded. Wildlife identification involved using one or more of the following observation techniques: active searching and capture, visual observations (binoculars), and identifying characteristic signs of wildlife (sounds, scat, tracks and burrows). Jurisdictional wetland determinations were performed utilizing delineation criteria prescribed in the "Corps of Engineers Wetland Delineation Manual" (Environmental Laboratory, 1987). Additional surveys for federally-protected species were conducted by NCDOT biologists Dale Suiter and Jim Hauser on 22 June 1999. 2. Physical Resources Soil and water resources occurring in the study area are discussed below. Soils and availability of water directly influence composition and distribution of flora and fauna in any biotic community. The project study area lies within the Coastal Plain Physiographic Province. The topography in this section of Onslow County is nearly flat to gently sloping, dissected by floodplains. Topography in the project area is somewhat sloping since it is located in the stream valley and floodplain area associated with Parrot Swamp. Project elevation is approximately 4.6 m (15.0 ft) above mean sea level (msl). a. Soils Three soil phases occur within project boundaries: Muckalee loam, Marvyn loamy fine sand 6-15% slope, and Norfolk loamy fine sand 2-6% slope. Muckalee loam is a poorly drained soil occurring on flood plains. Permeability is moderate, surface runoff is slow, and the seasonal high 7 water table is located at 0.1-0.5 m (0.5-1.5 ft) below the surface. Flooding occurs frequently for brief periods, and water may pond in the wider floodplains for long periods in winter. Muckalee loam is listed as hydric. Marvyn loamy sand 6-15% slope is a well-drained soil occurring short side slopes near large drainageways on uplands. Permeability is moderate, surface runoff is medium, and the seasonal high water table is located 0.9-1.5 m (3.0-5.0 ft) below the surface. This soil is subject to erosion if not protected by vegetation. Marvyn loamy fine sand 6-15% slope is listed as non-hydric, but may contain hydric inclusions of the Muckalee soil type. Norfolk loamy fine sand 2-6% slope is a well-drained soil occurring on uplands. Permeability is moderate, surface runoff is medium, and the seasonal high water table is located 1.1-1.8 m (3.5-6.0 ft) below the surface. Norfolk loamy fine sand is subject to erosion if not protected by cover vegetation, and is listed as non-hydric. Muckalee loam is difficult to manage for croplands and timber due to wetness and flooding, however, woodland productivity is rated as excellent. Wetness, periodic flooding, bank instability, and seepage are the major limitations for this soil. Marvyn loamy fine sand 6-15% slope is mainly used as woodland, with the major limitations for this soil being the slope and risk of erosion. Norfolk loamy fine sand 2-6% slope is used mainly for cropland. The major limitations of this soil are erosion where vegetation has been removed and, in areas used for building or sanitary facilities, high water table during wet periods. Soil core samples taken throughout the project area revealed soils with a sandy/ silty texture. The soils did exhibit hydric conditions, such as low chroma colors, in low areas of the flood plain. Therefore, hydric soil indicators, as defined in the "Corps of Engineers Wetland Delineation Manual", 1987, were observed within the project study area. b. Water Resources This section contains information concerning those water resources likely to be impacted by the project. Water resource information encompasses physical aspects of the resource, its relationship to major water systems, Best Usage Standards and water quality of the resources. Probable impacts to these water bodies are also discussed, as are means to minimize impacts. 8 Waters Impacted and Characteristics Parrot Swamp will be the only surface water resource directly impacted by the proposed project. Parrot Swamp is located in sub-basin 030501 of the White Oak River Basin. Parrot Swamp is a tributary to Queen Creek, and -has its confluence with the creek approximately 32 km (2.0 mi stream channel distance) downstream of Bridge No. 91. Queen Creek is a 3.1 km (10.1 mi) long coastal stream flowing into the White Oak River estuary in the vicinity of the town of Swansboro and Bogue Inlet. Parrot Swamp, at Bridge No. 91, is approximately 3.0 m (10.0 ft) wide and has an average depth of 0.6-0.9 m (2.0-3.0 ft) at this location. The substrate is composed of silt, sand and gravel. Parrot Swamp is a blackwater stream, with a visibility of less than 0.6 m (2.0 ft). Best Usage Classification The Division of Water Quality (DWQ) has assigned streams a best usage classification. The classification of Parrot Swamp [index no. 19-41- 16-4] is SA. The SA classification denotes waters suitable for shellfishing for market purposes, primary recreation, aquatic life propagation and survival, fishing, wildlife, and secondary recreation. The classification of SA automatically includes Parrott Swamp in the supplemental classification of High Quality Waters (HQW). No Water Supplies (WS-I: undeveloped watersheds or WS-II: predominately undeveloped watersheds) or Outstanding Resource Waters (ORW) occur within 1.6 km (1.0 mi) of project study area. Water ality The DWQ has initiated a whole basin approach to water quality management for the 17 river basins within the state. To accomplish this goal the DWQ, formerly known as the Department of Environmental Management (DEM), collects biological, chemical and physical data that can be used in basinwide assessment and planning. All basins are reassessed every five years. Prior to the implementation of the basinwide approach to water quality management, the Benthic Macroinvertebrate Ambient Network (managed by the DEM) assessed water quality by sampling for benthic macroinvertebrate organisms at fixed monitoring sites throughout the state. Some macroinvertebrates are sensitive to very subtle changes in water quality; thus, the species richness and overall biomass of these organisms are reflections of water quality. A benthic C 9 macroinvertebrate collection site is located at the mouth of Queen Creek in Onslow County, approximately 4.8 km (3.0 mi stream channel distance) from the project study area. This station was sampled once in August 1994 and received a taxa richness rating of 103, a Biotic Index value of 2.3, and a bioclassification of Estuarine (DWQ 1997). The Ambient Monitoring System (AMS) is a network of stream, lake and estuarine water quality monitoring stations strategically located for the collection of physical and chemical water quality data. The type of water quality data or parameters that are collected is determined by the waterbody's freshwater or saltwater classification and corresponding water quality standards (DWQ 1997). Data collected at an AMS monitoring site at the mouth of the White Oak River (NC 24 at Swansboro) between January 1990 and December 1994 show no excursions from NC Water Quality Criteria for all tested parameters except copper (DWQ, 1997). The increased levels of copper are seen throughout the whole basin, and are therefore probably not due to a point source. Parrot Swamp is, however, listed as a partially supporting impaired water due to fecal coliform contamination, and shellfishing in this area has been prohibited or restricted (DWQ 1997). Point source dischargers located throughout North Carolina are permitted through the National Pollutant Discharge Elimination System (NPDES) Program. Any discharger is required to register for a permit. In June 1998, DWQ issued a NPDES permit to NCDOT authorizing it to discharge stormwater into Waters of the United States. No other point source dischargers are located within a 1.6 km (1.0 mi) radius of the project study area. Summary of Anticipated Impacts Replacing an existing structure in the same location with a temporary detour during construction is almost always preferred to relocating the road entirely. It poses the least risk to aquatic organisms and other natural resources, whereas bridge replacement on a new location usually results in more severe impacts. Alternates 1 and 2 involve the current right of way and a temporary detour. Utilizing the full existing right of way width of 18.3 m (60.0 ft) and temporary detour width of 30.5 m (100.0 ft), anticipated impacts to Parrot Swamp for Alternate 1 will be 48.8 m (160.0 ft) and Alternate 2 will be 39.6 m (130.0 ft). Alternate 3 calls for relocation of the bridge. using the existing bridge as a detour during construction. Utilizing the full existing right of way width of 18.3 m (60.0 ft) and new right of way width of 30.5 m (100.0 ft), anticipated impacts to Parrot Swamp for Alternate 3 will be 48.8 m (160.0 ft). Usually, 10 project construction does not require the entire right of way, therefore, actual impacts may be considerably less. . Project construction for any of the three alternates may result in the following impacts to surface waters: 1. Increased sedimentation and siltation from construction and/or erosion. 2. Changes in light incidence and water clarity due to increased sedimentation and vegetation removal. 3. Alteration of water levels and flows due to interruptions and/additions to surface and ground water flow from construction. 4. Changes in water temperature due to streamside vegetation removal. 5. Increased nutrient loading during construction via runoff from exposed areas. 6. Increased concentration of toxic compounds from highway runoff, construction and toxic spills. . Precautions will betaken to minimize impacts to water resources in the study area. NCDOT's Best Management Practices (BMP) for the Protection of Surface Waters and Sedimentation Control guidelines in Sensitive Watersheds will be strictly enforced during the construction stage of the project. Provisions to preclude contamination by toxic substances during the construction interval will also be strictly enforced. 3. Biotic Resources Biotic resources include aquatic and terrestrial ecosystems. This section describes those ecosystems encountered in the study area, as well as the relationships between fauna and flora within these ecosystems. Composition and distribution of biotic communities throughout the project area are reflective of topography, hydrologic influences and past and present land uses in the study area. Descriptions of the terrestrial systems are presented in the context of plant community classifications and follow descriptions presented by Schafale and Weakley (1990) where possible. Dominant flora and fauna observed, or likely to occur, in each community are described and discussed. 11 Scientific nomenclature and common names (when applicable) are provided for each animal and plant species described. Plant taxonomy generally follows Radford, et al. (1968). Animal taxonomy follows Martof, et al. (1980), Menhenick (1991), Potter, et al. (1980), and Webster, et al. (1985). Subsequent references to the same organism will include the common name only. Fauna observed during the site visit are denoted by an asterisk (*). Published range distributions and habitat analysis are used in estimating fauna expected to be present within the project area. a. Biotic Communities Five communities are identified in the project study area: Coastal Plain Small Stream Swamp (Blackwater Subtype), Bottomland Hardwoods (Blackwater Subtype), Coastal Plain Perennial Stream, Mesic Pine Flatwoods, and maintained/ disturbed. Community boundaries within the study area are well defined without a significant transition zone between them, except in the case of the Coastal Plain Small Stream Swamp, which merges into the Bottomland Hardwoods. Faunal species likely to occur within the study area will exploit all communities for shelter and foraging opportunities or as movement corridors, except those fauna restricted to the aquatic environment. Coastal Plain Small Stream Swamp (Blackwater Subtype) The Coastal Plain Small Stream Swamp is present along the Parrot Swamp corridor on both sides of SR 1509. The hydrology of this . community type is driven by intermittent flooding during high flow periods. Periodic flooding provides nutrient input through sediment deposition making this system very productive. However, periodic flooding can also be a destructive factor during large storm events by undercutting banks and eroding soils. The canopy is composed of American elm (Ulmus americana), tulip poplar (Liriodendron tulipifera), green ash (Fraxinus pennsylvanica), red maple (Acer rubrum), red bay (Persea borbonia), loblolly pine (Pinus taeda), water oak (Quercus nigra) and sweetgum (Liquidambar styraciflua). The shrub layer consists of saplings of the canopy trees, Virginia willow (Itea virginica), Chinese privet (Ligustrum sinense), common waxmyrtle (Myrica cerifera) and tag alder (Alnus serrulata). Flowering dogwood (Corpus florida) and persimmon (Diospyros virginiana) were occasionally found on isolated hummocks within the floodplain. Herbs within this community include net-veined chain fern (Woodu7ardia areolata), sedges (Carex spp.), and smartweed (Polygonum lapathifolium). The vine layer is composed of 12 Japanese honeysuckle (Lonicera japonica), climbing hempweed (Mikania scandens), climbing hydrangea (Decumeria barbara) and greenbrier (Smilax bona-nox). Bottomland Hardwoods (Blackwater Subtype) Bottomland hardwoods are present on both sides of the project area, adjacent to the Coastal Plain Small Stream Swamp. The hydrology of this community is also driven by seasonal or intermittent flooding; however, this community tends to be farther from the stream channel than the Coastal Plain Small Stream Swamp. The canopy layer in this community consists of loblolly pine, red maple and sweetgum. The shrub layer consists of saplings of the canopy trees, American holly (Ilex opaca), and Virginia willow. The herb layer includes smartweed and net-veined chain fern. The vine layer is composed of Japanese honeysuckle, kudzu (Peuraria lobata), poison ivy (Toxicodendron radicans) and greenbrier. Mesic Pine Flatwoods The Mesic Pine Flatwoods area is confined to the extreme northern and southern ends of the project, on both sides of the road. This area has sandy soils and is higher in elevation than the rest of the project. This community appears to be disturbed by human activity. The canopy layer in this community consists of loblolly pine and sweetgum. The shrub layer consists of saplings of the canopy trees, persimmon, and occasional flowering dogwoods. The herb layer includes aster (Aster spp.) and goldenrod (Solidago spp.). The vine layer is composed of Japanese honeysuckle, kudzu, poison ivy and greenbrier. Maintained/ Disturbed The maintained/ disturbed community is restricted to road shoulders along SR 1509 and the area around the bridge and is present along the entire length of the project. Flora within this periodically maintained community includes: fescue (Festuca spp.), goldenrod, dock (Rumex spp.), paspalum (Paspalum spp.), beggar-ticks (Bidens spp.), smartweed, ragweed (Ambrosia artemesiifolia), and calico aster (Aster lateriflorus). The area immediately around the bridge, which is less intensively maintained, also contains black willow (Salix nigra). Eastern red cedar (Juniperus virginiana), is occasionally seen in the woods along the edge of this community. 13 Coastal Plain Perennial Stream This area of Parrot Swamp is a small blackwater stream. The only vegetation associated with the stream itself in this area is smartweed and beggar-ticks, both of which were growing into the stream channel in the vicinity of the bridge. There is no visible submerged aquatic vegetation. b. Wildlife The physical characteristics of the terrestrial and aquatic communities in an area will affect the fauna that are present and use the area. This section addresses the fauna likely to be found in the project study area. Terrestrial Fauna Fauna associated with the communities in the project area includes Carolina anole* (Anolis carolinensis), spring peeper (Hyla crucifer), gray squirrel (Sciurus carolinensis), opossum (Didelphis Virginian) and raccoon (Procyon lotor). White-tailed deer (Odocoileus virginianus) will use these forest communities for cover and will forage on twigs and leaves as well as mast. Avian species utilizing these areas include the prothonotary warbler (Protonotaria citrea), red-eyed vireo (Vireo olivaceus), Eastern bluebird* (Sialia sialis), yellow-rumped warbler (Dendroica coronata), yellow-bellied sapsucker (Sphyrapicus varius), red-bellied woodpecker (Melanerpes carolinus), and turkey vulture* (Cathartes aura). Aquatic Fauna Fauna associated with the aquatic community includes various invertebrate and vertebrate species. Prey fish including mosquitofish* (Gambusia affinis) provide foraging opportunities for pumpkinseed sunfish* (Lepomis gibbosus), pirate perch* (Aphredoderus sayanus) and chain pickerel (Esox niger). Invertebrates that are present include crayfish (family Cambaridae), nymphal stages of dragonflies* and damselflies* (Order Odonata), whirligig beetles* (family Gyrinidae) and shrimp* (Palaemonetes spp.). The southern dusky salamander (Desmognathus auriculatus), green frog (Rana clamitans), snapping turtle (Chelydra serpentina) and brown water snake (Nerodia taxispilota) are common permanent residents in this community. Anadromous fish such as-alewife (Alosa pseudoharengus) and blueback herring (A. aestivalis) use coastal 14 streams as spawning habitat. C. Summary of Anticipated Impacts Construction of the subject project will have various impacts on the biotic resources. described. Any construction related activities in or near these resources have the potential to impact biological functions. This section quantifies and qualifies impacts to the natural resources in terms of area impacted and ecosystems affected, for each of the three project alternates. Temporary and permanent impacts are also considered here. Calculated impacts to terrestrial resources reflect the relative abundance of each community present within the study area. Project construction will result in clearing and degradation of portions of these communities. Table 2 summarizes potential quantitative losses to these biotic communities, resulting from project construction. Estimated impacts for each alternate are derived using the entire proposed right of way width. Usually, project construction does not require the entire right of way; therefore, actual impacts may be considerably less. Table 2.

Plant communities found within the proposed project area serve as nesting and sheltering habitat for various wildlife. Replacing Bridge NQ. 91 and its associated improvements will reduce habitat for faunal species, thereby diminishing faunal numbers. However, due to the size and scope of this project, it is anticipated that impacts to fauna will be minimal. Areas modified by construction (but not paved) will become road 15 shoulders and early successional habitat. Reduced habitat will displace some wildlife further from the roadway while attracting other wildlife by the creation of more early successional habitat. Animals temporarily displaced by construction activities will repopulate areas suitable for the species. Aquatic communities are sensitive to even small changes in their environment. Stream channelization, scouring, siltation, sedimentation and erosion from construction-related work will affect water quality and biological constituents. Although direct impacts may be temporary, environmental impacts from these construction processes may result in long term or irreversible effects. Impacts often associated with in-stream construction include increased channelization and scouring of the streambed. In-stream construction alters the stream substrate and may remove streamside vegetation at the site. Disturbances to the substrate will produce siltation, which clogs the gills and/or feeding mechanisms of benthic organisms (sessile filter-feeders and deposit-feeders), fish and amphibia n species. Benthic organisms can also be covered by excessive amounts of sediment. These organisms are slow to recover or repopulate a stream The removal of streamside vegetation and placement of fill material at the construction site alters the terrain. Alteration of the streambank enhances the likelihood of erosion and sedimentation. Revegetation stabilizes and holds the soil thus mitigating these processes. Erosion and sedimentation carry soils, toxic compounds and other materials into aquatic communities at the construction site. These processes magnify turbidity and can cause the formation of sandbars at the site and downstream, thereby altering water flow and the growth of vegetation. Streamside alterations also lead to more direct sunlight penetration and to elevations of water temperatures, which may impact many species. Anadromous fish are a valuable resource and their migration must not be adversely impacted. The Draft Stream Crossing Guidelines for Anadromous Fish Passage provides guidance to the NCDOT to ensure that replacement of existing stream crossing structures will not impede the movement of anadromous fish. These guidelines should be used in projects located in the coastal plain. The draft guidelines are given in the appendix. 4. jurisdictional Topics This section provides descriptions, inventories and impact analysis 16 pertinent to two important issues--Waters of the United States and rare and protected species. a. Waters of the United States Surface waters and wetlands fall under the broad category of "Waters of the United States," as defined in Section 33 of the Code of Federal Register (CFR) Part 328.3. Wetlands, defined in 33 CFR 328.3, are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted to life in saturated conditions. Any action that proposes to place fill into these areas falls under the jurisdiction of the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean Water Act (33 U.S.C. 1344). Characteristics of Wetlands and Surface Waters Potential wetland communities were investigated pursuant to the 1987 "Corps of Engineers Wetland Delineation Manual". The three parameter approach is used, where hydric soils, hydrophytic vegetation and prescribed hydrologic characteristics must all be present for an area to be considered a wetland. Two types of wetlands are present within the project area, and are associated with the alluvial forest:. The wetlands can be described as palustrine forested broad-leaved deciduous/ needle-leaved evergreen seasonally flooded (PF01/4C, Cowardin, et al), and palustrine forested broad-leaved deciduous/ needle-leaved evergreen temporarily flooded (PF01/4A, Cowardin, et al). These wetlands can also be described as Coastal Plain Small Stream Swamp (Blackwater Subtype) and Bottomland Hardwoods, respectively (Schafale and Weakley,1990). Soils within the wetland areas have a silty texture and a Munsell color notation of 25Y 5/2. Hydrological indicators include saturated soil, the presence of oxidized rhizospheres and drift lines. Vegetation within the wetlands include green ash, red maple, Virginia willow, net-veined chain fern, climbing hempweed and climbing hydrangea. Parrot Swamp is a jurisdictional surface water under Section 404 of the Clean Water Act (33 U.S.C. 1344). Discussion of the biological, physical and water quality aspects of Parrot Swamp are presented in previous sections of this report. 17 Summary of Anticipated Impacts Table 3 summarizes anticipated impacts to wetland and surface water areas in the project area for each alternate. Anticipated impacts to these areas are determined by using the entire project right of way width, including right of way for the temporary detours. Usually, project construction does not require the entire right of way; therefore, actual wetland and surface water impacts may be considerably less.

Again, it should be noted that Alternates 1 and 2 present mainly temporary impacts, while Alternate 3 is a permanent relocation of the road. Permits Impacts to jurisdictional surface waters are anticipated. The subject project is located within a county that is under the jurisdiction of the Coastal Area Management Act (CAMA), which is administered by the Division of Coastal Management (DCM). The DCM is the lead permitting agency for projects located within its jurisdiction. The DCM will not issue a LAMA Major Development Permit unless NCDOT receives a Stormwater Management Certification from the Division of Water Quality (DWQ)- CAMA directs the Coastal Resources Commission (CRC) to identify and designate Areas of Environmental Concern (AEC's) in which 18 uncontrolled development might cause irreversible damage to property, public health, and the natural environment. CAMA necessitates a permit if the project meets all of the following conditions: it is located in one of the 20 counties covered by CAMA; it is in or affects an AEC designated by CRC; it is considered "development" under the terms of the Act, and; it does not qualify for an exemption identified by the Act or by the CRC. This project may require a CAMA permit. The CAMA major development permit application form serves as an application for three other state permits and for permits from the Corps of Engineers (COE) required by section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. The state permits include: (1) Permit to excavate and/or fill; (2) Easement in lands covered by water, and; (3) 401 Water Quality Certification. AEC information: (1) Estuarine waters are an AEC which CAMA defines as all the waters of the Atlantic Ocean within the boundaries of North Carolina and all the waters of the bays, sounds, rivers and tributaries there to seaward of the dividing line between coastal fishing waters and inland fishing waters. This definition of estuarine waters was also set forth in an agreement adopted by the Wildlife Resources Commission (WRC) and the Department of Natural Resources and Community Development. (2) A Public Trust AEC includes all waters and submerged lands in the coastal region where the public has the rights of use and/or ownership, including rights of navigation and recreation. This AEC also covers all lands under these waterways and the submerged minerals and biological resources that these submerged lands contain. (3) A Coastal Wetland AEC is defined as any marsh subject to occasional flooding by tides (including wind tides). Tidal waters may reach the marsh by either natural or artificial watercourses. Coastal Wetland AEC's, by definition, must contain certain plant species listed in the CAMA regulations. (4) An Estuarine Shoreline AEC includes all shorelines within 23.0 m (75.0 ft) landward of the mean high water level, or normal water level, of the estuarine waters. 19 A Section 404 Nationwide Permit 23 is likely to be applicable for all impacts to Waters of the United States from the proposed project. This permit authorizes activities undertaken, assisted, authorized, regulated, funded or financed in whole, or part, by another Federal agency or department where that agency or department has determined that pursuant to the council on environmental quality regulation for implementing the procedural provisions of the National Environmental Policy Act; (1) that the activity, work, or discharge is categorically excluded from environmental documentation because it is included within a category of actions which neither individually nor cumulatively have a significant effect on the human environment, and; (2) that the office of the Chief of Engineers has been furnished notice of the agency' or department's application for the categorical exclusion and concurs with that determination. A North Carolina DWQ Section 401 Water Quality General Certification is required prior to the issuance of the Section 404 permit. Section 401 Certification allows surface waters to be temporarily impacted for the duration of the construction or other land manipulations. Mitigation The COE has adopted, through the Council on Environmental Quality (CEQ), a wetland mitigation policy which embraces the concept of "no net loss of wetlands" and sequencing. The purpose of this policy is to restore and maintain the chemical, biological and physical integrity of Waters of the United States, specifically wetlands. Mitigation of wetland impacts has been defined by the CEQ to include: avoiding impacts (to wetlands), minimizing impacts, rectifying impacts, reducing impacts over time and compensating for impacts (40 CFR 1508.20). Each of these three aspects (avoidance, minimization and compensatory mitigation) must be considered sequentially. Avoidance Avoidance mitigation examines all appropriate and practicable possibilities of averting impacts to Waters of the United States. A 1990 Memorandum of Agreement (MOA) between the Environmental Protection Agency (EPA) and the COE states that in determining "appropriate and practicable" measures to offset unavoidable impacts, 20 such measures should be appropriate to the scope and degree of those impacts and practicable in terms of cost, existing technology and logistics in light of overall project purposes. Minimization Minimization includes the examination of appropriate and practicable steps to reduce the adverse impacts to Waters of the United States. Implementation of these steps will be required through project modifications and permit conditions. Minimization typically focuses on decreasing the footprint of the proposed project through the reduction of median widths, right of way widths, fill slopes and/or road shoulder widths. Other practical mechanisms to minimize impacts to Waters of the United States crossed by the proposed project include: strict enforcement of sedimentation control BMP's for the protection of surface waters during the entire life of the project; reduction of clearing and grubbing activity; reduction/ elimination of direct discharge into streams; reduction of runoff velocity; re-establishment of vegetation on exposed areas, judicious pesticide and herbicide usage; minimization of "in-stream" activity; and litter/ debris control. Compensatory Mitigation Compensatory mitigation is not normally considered until anticipated impacts to Waters of the United States have been avoided and minimized to the maximum extent possible. It is recognized that "no net loss of wetlands" functions and values may not be achieved in each and every permit action. Appropriate and practicable compensatory mitigation is required for unavoidable adverse impacts that remain after all appropriate and practicable minimization has been required. Compensatory actions often include restoration, creation and enhancement of Waters of the United States. Such actions should be undertaken in areas adjacent to or contiguous to the discharge site. Compensatory mitigation is not usually necessary with a Nationwide Permit # 23. b. Rare and Protected Species Some populations of fauna and flora have been in, or are in, the process of decline either due to natural forces or their inability to coexist with human activities. Federal law (under the provisions of the Endangered Species Act of 1973, as amended) requires that any action likely to adversely affect a species classified as federally protected be subject to review by the Fish and Wildlife Service (FWS). Other species 21 may receive additional protection under separate state laws. Federally-Protected Species Plants and animals with federal classifications of Endangered (E), Threatened (T), Proposed Endangered (PE) and Proposed Threatened (PT) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act (ESA) of 1973, as amended. As of 28 February 2000, the FWS lists the following federally-protected species for Onslow County (see Table 4). A brief description of each species' characteristics and habitat follows. Table 4.

"T(S/A)" denotes Threatened due to similarity of appearance (a species that is threatened due to similarity of appearance with other rare species and is listed for its protection. These species are not biologically endangered or threatened and are not subject to Section 7 consultation.) Alligator mississippiensis (American alligator) Threatened due to Similarity Animal Family: Crocodylidae of Appearance Date Listed: 6/4/87 The American alligator is a large roughbacked reptile with a broad rounded snout. Most adults range in size from 6 to 12 feet. Habitat for the alligator includes river systems, canals, lakes, swamps, bayous, and coastal marshes. The alligator will eat almost anything of suitable size including mammals, reptiles, amphibians, birds, fish, and crustaceans. Species that have the federal classification of Threatened due to Similarity of Appearance are not biologically endangered or threatened 22 and do not receive protection under Section 7. However, due to its similarity of appearance to other protected crocodilians, federal regulations, such as hide tagging requirements, are maintained on the commercial trade to help control illegal taking of the protected species. The NHP database of rare species and unique habitats contains no record of American alligator within the study area. Caretta caretta (loggerhead turtle) Threatened Animal Family: Cheloniidae Date Listed: 7/28/78 Loggerhead turtles can be distinguished from other sea turtles by its unique reddish-brown color. The loggerhead is characterized by a large head and blunt jaws. Additionally, they have 5 or more costal plates with the first touching the nuchal and 3 to 4 bridge scutes. The loggerhead nests on suitable beaches from Ocracoke Inlet, North Carolina through Florida and on a small scale off of the Gulf States. There are also major nesting grounds on the eastern coast of Australia. It lives worldwide in temperate to subtropical waters. Loggerheads nest nocturnally between May and September on isolated beaches that are characterized by fine grained sediments. It is mainly carnivorous, feeding on small marine animals. BIOLOGICAL CONCLUSION NO EFFECT - Nesting beaches are not present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of loggerhead turtles in the project vicinity. Therefore, project construction will not affect the loggerhead turtle. Charadrius melodus (piping plover) Threatened Animal Family: Charadriidae Date Listed: 12/11/85 The piping plover is a small migratory shorebird that resembles a sandpiper. It can be identified by the orange legs and black band around the base of its neck. During the winter the plover loses its black band, its legs fade to pale yellow, and the bill fades to black. Breeding birds are characterized by white underparts, a single black breastband, and a black bar across the forehead. 23 The piping plover breeds along the east coast. In North Carolina, nesting occurs in flat areas with fine sand and mixtures of shells and pebbles. They nest most commonly where there is little or no vegetation, but some may nest in stands of beachgrass. The nest is a shallow depression in the sand that is usually lined with shells and pebbles. The piping plover is very sensitive to human disturbances. The presence of people can cause the plover to abandon its nest and quit feeding. BIOLOGICAL CONCLUSION NO EFFECT No suitable habitat in the form of beaches with fine sand and mixtures of sand and pebbles is present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of piping plover in the project vicinity. This species is known only from outer barrier beaches. Therefore, project construction will not affect the piping plover. Chelonia mydas (green sea turtle) Threatened Animal Family: Cheloniidae Date Listed: 7/ 28/ 78 The distinguishing factors found in the green sea turtle are the single clawed flippers and a single pair of elongated scales between the eyes. This sea turtle has a small head and a strong, serrate, lower jaw. The green sea turtle is found in temperate and tropical oceans and seas. Nesting in North America is limited to small communities on the east coast of Florida, requiring beaches with minimal disturbances and a sloping platform for nesting (they do not nest in NC). The green sea turtle can be found in shallow waters. They are attracted to lagoons, reefs, bays, mangrove swamps and inlets where an abundance of marine grasses, the principal food source of the green turtle, can be found. BIOLOGICAL CONCLUSION NO EFFECT Nesting beaches are not present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of green turtles in the project vicinity. Therefore, project construction will not affect the green turtle. 24 Dermochelys coriacea (leatherback sea turtle) Endangered Animal Family: Dermochelydae Date Listed: 6/ 2/ 72 The leatherback sea turtle is the largest of the marine turtles. Unlike other marine turtles, the leatherback has a shell composed of tough leathery skin. The carapace has 7 longitudinal ridges and the plastron has 5 ridges. The leatherback is black to dark brown in color and may have white blotches on the head and limbs. Leatherbacks are distributed world-wide in tropical waters of the Atlantic, Pacific, and Indian oceans. Leatherbacks prefer deep waters and are often found near the edge of the continental shelf. In northern waters they are reported to enter bays, estuaries, and other inland bodies of water. Leatherback nesting requirements are very specific, they need sandy beaches backed with vegetation in the proximity of deep water and generally with rough seas. Beaches with a suitable slope and a suitable depth of coarse dry sand are necessary for the leatherback to nest. Major nesting areas occur in tropical regions and the only nesting population in the United States is found in Martin County, Florida. Leatherback nesting occurs from April to August. Artificial light has been shown to cause hatchlings to divert away from the sea. Leatherbacks feed mainly on jellyfish. They are also known to feed on sea urchins, crustaceans, fish, mollusks, tunicates, and floating seaweed. BIOLOGICAL CONCLUSION NO EFFECT Nesting beaches are not present within the project area. Project construction is confined to upstream areas of the estuary and not in beach areas. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of leatherback turtles in the project vicinity. Therefore, project construction will not affect the leatherback turtle. Felis concolor cougar (eastern cougar) Endangered Animal Family: Felidae Date Listed: 6/4/73 Cougars are tawny colored with the exception of the muzzle, the backs of the ears, and the tip of the tail, which are black. In North Carolina the cougar is thought to occur in only a few scattered areas, possibly 25 including coastal swamps and the southern Appalachian Mountains. The eastern cougar is found in large remote wilderness areas where there is an abundance of their primary food source, white-tailed deer. A cougar will usually occupy a range of 25.0 miles and they are most active at night. BIOLOGICAL CONCLUSION NO EFFECT Habitat in the form of large remote wilderness does not exist within the project area. The project area is located close to the moderately developed areas of Swansboro and Jacksonville, and it is not likely that cougars would use this area. The N.C. Natural Heritage Program database of rare species and unique habitats was reviewed and revealed no records of eastern cougars in the project vicinity. Therefore, project construction will not affect the eastern cougar. Picoides borealis (red-cockaded woodpecker) Endangered Animal Family: Picidae Date Listed: 10/13/70 The adult red-cockaded woodpecker (RCW) has plumage that is entirely black and white except for small red streaks on the sides of the nape in the male. The back of the RCW is black and white with horizontal stripes. The breast and underside of this woodpecker are white with streaked flanks. The RCW has a large white cheek patch surrounded by the black cap, nape, and throat. The RCW uses open old growth stands of southern pines, particularly longleaf pine (Pinus palustris), for foraging and nesting habitat. A forested stand must,contain at least 50% pine, lack a thick understory, and be contiguous with other stands to be appropriate habitat for the RCW. These birds nest exclusively in trees that are > 60 years old and are contiguous with pine stands at least 30 years of age. The foraging range of the RCW is up to 200.0 hectares (500.0 acres). This acreage must be contiguous with suitable nesting sites. These woodpeckers nest exclusively in living pine trees and usually in trees that are infected with the fungus that causes red-heart disease. Cavities are located in colonies from 3.6-30.3 m (12-100 ft) above the ground and average 9.1-15.7 m (30-50 ft) high. They can be identified by a large encrustation of running sap that surrounds the tree. The RCW lays its eggs in April, May, and June; the eggs hatch approximately 38 days later. BIOLOGICAL CONCLUSION NO EFFECT 26 Nesting and foraging habitat requirements considered necessary for the RCW are not present within the project vicinity. There are no old growth stands of southern pine in vicinity of the project. Additionally, forested areas in the project vicinity consist of mixed pine/ hardwood forests, which are less than fifty percent pine and generally have a dense understory of hardwood saplings and shrubs. The NC Natural Heritage Program database of rare species and unique habitats has no record for the presence of the RCW within the project vicinity. Therefore, no impact to the red-cockaded woodpecker will result from project construction. Amaranthus pumilus (seabeach amaranth) Threatened Plant Family: Amaranthaceae Date Listed: 4/ 7/ 93 Flowers Present: June to frost Seabeach amaranth is an annual legume that grows in clumps containing 5 to 20 branches and which are often over a foot across. The trailing stems are fleshy and reddish-pink or reddish in color. Seabeach amaranth has thick, fleshy leaves that are small, ovate-spatulate, emarginate and rounded. The leaves are usually spinach green in color, cluster towards the end of a stem, and have winged petioles. Flowers grow in axillary fascicles and the legume has smooth, indehsicent fruits. Seeds are glossy black. Both fruits and flowers are relatively inconspicuous and borne along the stem. Seabeach amaranth is endemic to the Atlantic Coastal Plain beaches. Habitat for seabeach amaranth is found on barrier island beaches functioning in a relatively dynamic and natural manner. Seabeach amaranth grows well in overwash flats at the accreting ends of islands and the lower foredunes and upper strands of noneroding beaches. Temporary populations often form in blowouts, sound-side beaches, dredge spoil, and beach replenishment. ' This species is very intolerant to competition and is not usually found in association with other species. Threats to seabeach amaranth include beach stabilization projects, all terrain vehicles (ATV's), herbivory by insects and animals, beach grooming, and beach erosion. BIOLOGICAL CONCLUSION NO EFFECT Suitable habitat in the form of barrier island beaches functioning in a relatively dynamic and natural manner does not exist within the project area. The project area is located in the upper reaches of the estuary and does not contain beach habitat. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no 27 records of seabeach amaranth in the project vicinity. Therefore, project construction will not affect the seabeach amaranth. Lysimachia asperulaefolia (rough-leaved loosestrife) Endangered Plant Family: Primulaceae Federally Listed: 6/ 12/ 87 Flowers Present: June Rough-leaved loosestrife is a perennial herb having slender stems and whorled leaves. This herb has showy yellow flowers, usually occurring in threes or fours. Fruits are present from July through October. Rough-leaved loosestrife is endemic to the coastal plain and sandhills of North and South Carolina. This species occurs in the ecotones or edges between longleaf pine uplands and pond pine pocosins (areas of dense shrub and vine growth usually on a wet, peaty, poorly drained soil), on moist to seasonally saturated sands and on shallow organic soils overlaying sand. .It has also been found to occur on deep peat in the low . shrub community of large Carolina bays (shallow, elliptical, poorly drained depressions of unknown origins). The areas it occurs in are fire maintained. Rough-leaved loosestrife rarely occurs in association with hardwood stands and prefers acidic soils. BIOLOGICL CONCLUSION NO EFFECT Rough-leaved loosestrife habitat in the form of ecotones or edges between longleaf pine uplands and pond pine pocosins is not present in the project study area. The study area contains bottomland hardwoods and small stream swamp forest. The N.C. Natural Heritage Program data base. of rare species and unique habitats was reviewed and revealed no records of rough-leaved loosestrife in the project vicinity. During a second site visit on 22 June 1999, areas of suitable habitat within the project study area were surveyed by NCDOT biologists Dale Suiter and Jim Hauser. A plant by plant survey was unsuccessful. No rough-leaved loosestrife plants were located. The NCNHP records were checked via ArcView that was last updated in January 1999. At that time, no populations of rough-leaved loosestrife were known from the project study area. This project will not affect rough-leaved loosestrife. Thalictrum cooleyi (Cooley's meadowrue) Endangered Plant Family: Ranunculaceae Federally Listed: 2/7/89 Flowers Present: late June July (best mid July) 28 Cooley's meadowrue is a rhizomatous perennial plant with stems that grow to one meter in length. Stems are usually erect in direct sunlight but are lax and may lean on other plants or trail along the ground in shady areas. Leaves are usually narrowly lanceolate and unlobed, some two or three lobed leaves can be seen. The flowers lack petals. Fruits mature from August to September. Cooley's meadowrue occurs in moist to wet bogs, savannas and savanna-like openings, sandy roadsides, rights-of-ways, and old clearcuts. This plant is dependent on some form of disturbance to maintain its habitat: All known populations are on circumneutral, poorly drained, moderately permeable soils of the Griffon series. Cooley's meadowrue only grows well in areas with full sunlight. BIOLOGICAL CONCLUSION NO EFFECT The project area does contain open sandy roadsides that could potentially support Cooley's meadowrue. The N.C. Natural Heritage Program data base of rare species and unique habitats was reviewed and revealed no records of rough-leaved loosestrife in the project vicinity. No individuals were observed during the initial site visit. During a second site visit on 22 June 1999, areas of suitable habitat within the project study area were surveyed by NCDOT biologists Dale Suiter and Jim Hauser. A plant by plant survey was unsuccessful. No Cooley's meadowrue plants were located. The NCNHP records were checked via ArcView that was last updated in January 1999. At that time, no populations of Cooley's meadowrue were known from the project study area. This project will not affect Cooley's meadowrue. Federal SRecies of Concern and State Listed Species There are 22 Federal Species of Concern (FSC) listed for Onslow County. Federal Species of Concern are not afforded federal protection under the ESA and are not subject to any of its provisions, including Section 7, until they are formally proposed or listed As Threatened or Endangered. Federal Species of Concern are defined as those species that may or may not be listed in the future. These species were formerly candidate species, or species under consideration for listing for which there was insufficient information to support a listing of Endangered, Threatened, Proposed Endangered and Proposed Threatened. Organisms 29 which are listed as Endangered (E), Threatened (T), Significantly Rare (SR), or Special Concern (SC) by the North Carolina Natural Heritage Program (NCNHP) list of rare plant and animal species are afforded state protection under the State Endangered Species Act and the North Carolina Plant Protection and Conservation Act of 1979. Table 5 lists-Federal Species of Concern, the species state status (if afforded state protection) and the presence of suitable habitat for each species in the study area. This species list is provided for information purposes as the status of these species may be upgraded in the future. Table 5.

We reported our available information on historic architectural and archaeological surveys and resources along with our recommendations. NCDOT provided project area photographs and aerial photographs at the meeting. Based upon our review of the photographs and the information discussed at the meeting, we offer our preliminary comments regarding this project. In terms of historic architectural resources, we are aware of no historic structures located within the area of potential effect. We recommend that no historic architectural survey be conducted for this project. There are no known archaeological sites within the proposed project area. Based on our present knowledge of the area, it is unlikely that any archaeological resources which may be eligible for inclusion in the National Register of Historic Places will be affected by the project construction. We, therefore, recommend that no archaeological investigation be conducted in connection with this project. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which indicates how NCDOT addressed our comments. The. above comments are made pursuant to Section 106 of the National Historic Preservation Act of 1966 and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codified at 36 CFR Part 800. Nicholas L. Graf 11/21/97, Page 2 Thank you for your cooperation and consideration.

Addendum to Categorical Exclusion Green Sheet August 2001 Page 1 of 1 Onslow County Bridge No. 91 on SR 1509 Over Parrot Swamp Federal Project MABRZ-1509 (4) State Project 8.2260901 TIP No. B-3358 I. BACKGROUND A Categorical Exclusion for the subject project was approved on April 27, 2000. A vicinity map for this project is shown in Figure 1. The original recommended alternative (Alternate 3) was to replace Bridge No. 91 on new alignment to the east of the existing bridge with a bridge approximately 18 meters (60 feet) in length. The U. S. Army Corps of Engineers preferred a temporary on-site detour, rather than a permanent relocation of the bridge. The temporary on-site detours in Alternates 1 and 2 are the same length, have the same design speed (100 km/h [60 mph]), and are in the same location as a permanent relocation of the road. To minimize impacts, a new alternative was studied with a shorter temporary detour. This alternative, Alternate 4, is now the recommended alternative. Alternate 4 is shown in Figure 2. Changes to the proposed project are described in this Addendum to Categorical Exclusion. All other information presented in the Categorical Exclusion for this project is valid. II. DISCUSSION Three alternatives were considered in the Categorical Exclusion. A fourth alternative was studied at the request of the U. S. Army Corps of Engineers. All four alternatives are listed below. Alternate 1 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. The on-site detour will be approximately 420 meters (1380 feet) in length. Two residences will be relocated as a result of construction of this alternative. The design speeds of the temporary detour and the proposed roadway will be 100 km/h (60 mph). Alternate 2 Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on a temporary on-site detour east of the existing bridge during construction. The on-site detour will be approximately 420 meters (1380 feet) in length. One business will be relocated as a result of construction of this alternative. The design speeds of the temporary detour and the proposed roadway will be 100 km/h (60 mph). Alternate 3 (Recommended in the CE) . Replace Bridge No. 91 on new alignment to the east of the existing bridge with a bridge approximately 18 meters (60 feet) in length. Traffic will be maintained on the existing bridge during construction. Two residences will be relocated as a result of construction of this alternative. The design speed of the proposed roadway will be 100 km/h (60 mph). Alternate 4 (New Recommended) Replace Bridge No. 91 in place with a bridge approximately 18 meters (60 feet) in length. The on-site detour will be approximately 213 meters (700 feet) in length. Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. No residences or businesses will be relocated as a result of construction of this alternative. The design speed of the temporary detour will be 70 km/h (45 mph). The design speed of the proposed roadway will be 100 km/h (60 mph). Alternate 4 is shown in Figure 2. Estimated costs of the alternatives studied are shown in Table 1. Table 1. Estimated Costs Alternate 1 Alternate 2 Alternate 3 (Recommended in the CE) Alternate 4 (New Recommended) Bridge $180,000 -$180,0001 $180,000 $180,000 Roadway Approaches $304.360 $304.034 $415.'00 $'71.167 Structure Removal $7;768 $7,768 $7,768 $6,880 Detour, Approaches, & Removal $475,632 $461,038 $0 $92,600 Misc. & Mobilization $172,240 $172,140 $212,032 $194,353 Engineering & Contingencies $210,000 $175,000 $135,000 $105,000 Total Construction $1;350.000 $1300.000 $950,000 $850;000 Right of Way & Utilities $54,700 $56,600 $68,000 $44,000 TOTAL PROJECT COST $1,404,700 $1?356,600 $1,018,000 $894.000 2 .k The estimated cost of the project, shown in the NCDOT 2002-2008 Transportation Improvement Program is $1,018,000, including $68,000 for right of way acquisition and $950,000 for construction. Calculated impacts to biotic resources reflect the relative abundance of each community present within the study area. Project construction will result in clearing and degradation of portions of these communities. Estimated impacts are derived using the project plan sheets provided by NCDOT's Roadway Design Unit. Table 2 summarizes potential quantitative losses due to project construction for each alternate studied. The paved roadway width has been excluded from the impact calculations. Wetland impacts occurring due to the construction of the detour bridge may be considered permanent impacts due to the design of the temporary bridge. Therefore, all impacts occurring from project construction will be considered permanent impacts. All wetland areas impacted by the temporary detour bridge will be restored to their original elevation prior to project construction and will be replanted with the appropriate wetland vegetation.

Estimated linear impacts are derived using the cut and fill lines for the detour and replacement bridges located on the design plans. Anticipated impacts to Parrot Swamp will be approximately 120.0 ft (36.6 m) for Alternate 4. However, Parrot Swamp will be bridged, therefore, actual surface water impacts will be considerably less. Other environmental consequences of the alternatives are considered to be approximately equal and are limited in scope. These impacts are accurately described in 3 the Categorical Exclusion. III. RECOMMENDATION Bridge No. 91 will be replaced as recommended in Alternate 4 in its existing location with a new structure approximately 18 meters (60 feet) in length. The clear roadway width of the bridge will be 12 meters (40 feet) to accommodate two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) rail offsets. The roadway approaching the bridge will consist of two 3.6-meter (12-foot) lanes with 2.4-meter (8-foot) grassed shoulders. The new bridge will be at approximately the same elevation as the existing bridge. Based on preliminary design, the design speed of the proposed roadway will be 100 km/h (60 mph). Traffic will be maintained on a temporary on-site detour west of the existing bridge during construction. The length of the temporary detour will be approximately 213 meters (700 feet). The design speed of the temporary detour will be 70 km/h (45 mph). 4 FIGURES N rORES' vla.< 12cksoninlfcl? J,I`a•?a1s-- 71 '? I ?

PROJECT SUMMARY: The N.C. Department of Transportation is proposing to replace the existing 36-foot long by 26-foot wide timber bridge over Parrot Swamp with a 60-foot long by 40- foot wide concrete bridge. A temporary fill causeway approximately 400-foot long leading to a 60-foot long temporary bridge spanning Parrot Swamp would be used as a detour during construction. FIELD INVESTIGATION REPORT NC DOT - B-3358 Onslow County, Bridge No. 91 PAGE 2 9. PROJECT DESCRIPTION : The site of this proposal is Bridge No. 91 on State Road 1509 (Queens Creek Road), 3.5 miles southwest of Swansboro at the crossing of Parrot Swamp, in Onslow C ounty. The general purpose of the project is to replace the deteriorated 36-foot long by 26-foot wide timber and concrete bridge with a 60-foot long by 40-foot wide concrete bridge spanning Parrot Swamp, while maintaining traffic flow on a temporary detour consisting of approximately 400 feet of temporary fill causeway and a 60-foot long temporary bridge spanning Parrot Swamp. Bridge No. 91 crosses Parrot Swamp approximately 1.75 miles up -stream of its confluence with Queen Creek. The bridge crossing Parrot Swamp is flanked with Coastal Plain Small Stream Swamp and Bottomland Hardwoods, except for the southwest and southeast quadrants, which are urbanized and currently support a night club and mobile home, respectively. Creek width at the crossing is approximately 22 feet with vertical clearance between the water and bridge bottom is approximately 7 feet with a 3-foot water depth. An approximately 600-foot long by 45-foot wide causeway was constructed through the Coastal Small Stream Swamp and Bottomland Hardwoods on Muckalee loam soils when the bridge was constructed. The Coastal Small Stream Swamp and Bottomland Hardwoods area consists of Sweetgum, Red Maple,. American Elm, Tulip Tree, Green Ash, Kudsu, Morning Glory and Cat Tail. Soils in the swamp and wetlands are mainly Muckalee loam with Norfolk and Marvyn loamy fine sands in the upper elevations of the bridge approaches as classified by the NC Soil Conservation Service. Approximate elevations on the site range between 1 feet and 11 feet above normal water level. No evidence of SAV beds was noted. The North Carolina Division of Water Quality classifies waters of Parrot Swamp as SA, HQW at the project site. Parrot Swamp is Primary Nursery Area, as designated by the North Carolina Division of Marine Fisheries. The Onslow County Land Use Plan designates the project area as Transitional, with all CAMA Areas of Environmental Concern designated as Conservation. The proposal is to replace the existing 36-foot long by 26-foot wide timber and concrete bridge with a 60-foot long by 40-foot wide pre-stressed concrete bridge on the existing alignment. The proposed bridge would have a vertical clearance equal to the existing bridge (approximately 7 feet). Constructing this project would include installing a rip rap over filter fabric temporary fill causeway with concrete deck on the west side of the bridge leading to a temporary 60 -foot bridge spanning Parrot Swamp in order to detour traffic flow during construction. Approximately 230 feet of the temporary causeway will be fill through 404 type wetlands and removed upon completion of construction and restored to the original elevation. The bridge will be installed using top down construction. The bridge is being widened from 26 feet to 40 feet to more closely correspond to the 12 foot paved travel lanes and 8 foot grassed shoulders of SR 1509. NC DOT has committed to strictly adhere to "Design Standards in Sensitive Watersheds" and use Best Management Practices for erosion control and bridge demolition. Approximately 12 feet of existing causeway under the new bridge will be removed in its entirety and another 12 feet of causeway will be tapered back to the new bridge bents and armored with rip rap. 2 ' FIELD INVESTIGATION REPORT NC DOT - B-3358, Onslow County, Bridge No. 91 PAGE 3 10. ANTICIPATED IMPACTS: As proposed, the construction of the temporary fill causeway and bridge detour with 2:1 fill slopes would require the filling of approximately 0.17 acres of 404 type wetlands and approximately 0.27 acres of impacts to high ground. To allow room for grading and fill, approximately 0.06 acres of 404 type wetlands would be cleared adjacent to the temporary detour fill slopes by NC DOT Method III (mechanical clearing and grubbing). The additional width of the bridge would cause approximately 336 square feet (0.01 acres) of additional shading impacts to Public Trust Waters AEC. Removal of 24 feet of previously filled causeway would result in the disturbance of approximately 960 square feet (0.02 acres) of high ground. In addition to the above mentioned high ground impacts, approximately 1.5 acres of high ground would be disturbed within the construction limits of this project. Approximately 6150 square feet (0.14 acres) of the above describe ground disturbance would be within the CAMA Coastal Shoreline AEC. No disturbance of the creek bottom is expected during the installation of the bridge. NC DOT has avoided and minimized the 404 type wetland excavation and fill impacts associated with this proposal by lengthening the bride from 36 feet to 60 feet, using 2:1 fill slopes for the temporary detour, using top down construction and moving the detour from the east side of the bridge to the west side of the bridge. NC DOT BMP's require dropping no materials from the bridge demolition in the waters regulated by CAMA. The NC DOT has proposed to use "Design Standards in sensitive Watersheds" BMP's to minimize the impacts of erosion. NC DOT proposes to plant the areas impacted for the temporary detour after the fill is removed and they are restored to their previous elevation. NC DOT would be impacting approximately 0.23 acres of 404 type wetlands caused by the temporary detour in this proposal and requests to debit the Clayhill Farms Mitigation Bank to offset these impacts. The collective disturbance area for the project is 2.03 acres. Bill Arrington September 16, 2002 Morehead City T Essential Fish Habitat Assessment Bridge Number 91 Over Parrot Swamp on SR 1509 TIP No. B-3358 Onslow County, North Carolina qll?,; iilQr: !'=` INTRODUCTION The Magnusbn-Stevens Fishery Conservation and Management Act (MSA), as amended by the Sustainable Fisheries Act of 1996 (Public law 104-267), requires Federal agencies to identify and protect important marine and anadromous fish habitat. Furthermore, it established procedures for the identification of Essential Fish Habitat (EFH) and a requirement for interagency coordination to further the conservation of Federally managed fisheries. The objective of this EFH assessment is to describe potential adverse effects to designated EFH for Federally managed fisheries species within the project area. It also describes conservation measures proposed to avoid, minimize, or otherwise offset potential adverse effects to designated EFH resulting from the proposed actions. DESCRIPTION OF PROPOSED ACTION The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge Number.9 l, over Parrot Swamp on SR 1509 in Onslow County, in-place with a new bridge. Traffic will be maintained on-site during construction utilizing a temporary detour bridge west of the existing bridge. Both the permanent and detour bridges will be 60 feet in length. No bents will be placed in Parrot Swamp for either of these structures, therefore minimizing impacts to the aquatic community. The demolition of the existing bridge may potentially result in temporary fill of approximately 10 yd3. The bridge rail and substructure will be removed without dropping them into waters of the U.S. There is potential for the components of the deck to be dropped into waters of the U.S. However, it is anticipated that the bridge will be removed without dropping components into the water. During construction. Best Management Practices for Bridge Demolition and Removal will be followed. BIOLOGICAL RESOURCES Aquatic communities located within the project area consist of Coastal Plain Small Stream Swamp and open water. The Coastal Plain Small Stream Swamp community is present along the Parrot Swamp corridor on both sides of SR 1509. Periodic flooding of this community provides nutrient input through sediment deposition making this system very productive. Vegetative species occurring in this community include American elm (Ulmus americana), tulip poplar (Liriodendron tulipifera), green ash (Fraxinus pennsylvanica). red maple (Acer rubrum), red bay (Persea borbonia), loblolly pine (Pines taeda), water oak (Ouercus nigra), sweetgum (Liquidambar styraciflua), Virginia I , willow (Itea virginica), Chinese privet (Ligustrum sinense), common waxmyrtle (Myrica cerifera), tag alder (Alnus serrulata), netted chain fern (Woodwardia areolata), sedges (Carex spp.), and smartweed (Polygonum lapathifolium). Parrot Swamp flows into Queen Creek approximately 2.0 miles downstream of Bridge Number 91. Queen Creek empties into the Intracoastal Waterway approximately 1.0 mile from the confluence of Parrot Swamp and Queen Creek. Neither Parrot Swamp nor Queen Creek are listed as waterbodies in which EFH species are found according to the species list distributed by the National Marine Fisheries Service (NMFS), dated October 1999. Therefore, Table 1 represents the EFH species listed for Bogue Inlet, the closest waterbody to the proposed project listed by NMFS. The habitat in Bogue Inlet differs from Parrot Swamp. For that reason, Table 2 lists species likely to be present in Parrot Swamp based on habitat requirements, including, but not limited to, salinity levels, water temperature, and water depth. POTENTIAL ADVERSE EFFECTS Project activities directly affecting EFH may include the temporary fill placed in the Coastal Plain Small Stream Swamp community associated with the temporary bridge and approaches and stabilization measures. The proposed alternative has minimal impacts on natural communities. Based on the current design, permanent impacts to the Coastal Plain Small Stream Swamp community will be approximately 0.23 acres. These impacts are associated with the temporary fill and mechanized clearing that will occur due to the temporary detour structure. Temporary impacts to open water may include temporary fill due to bridge demolition. However, no fill is expected to occur from bridge demolition. These activities can be scheduled to avoid specific spawning, harvesting and/or otherwise important dates for individual species. CONSERVATION MEASURES Throughout the design process, this project was designed to avoid and minimize impacts to jurisdictional and aquatic areas. Specific strategies include redesigning the project with the purpose of constructing the temporary detour bridge and approaches on the western side of SR 1509 instead of permanently realigning the roadway along the eastern side. The eastern side consists of wetlands that are of comparatively higher quality than the wetlands located on the western side. Detour fill slopes were reduced to 2:1 to reduce temporary roadway fill. Parrot Swamp is classified as SA waters by the Division of Water Quality and is designated by North Carolina Division of Marine Fisheries as a Primary Nursery Area. Therefore, NCDOT will strictly adhere to "Design Standards in Sensitive Watersheds" (15A NCAC 04B .0024) (High Quality Water Standards) throughout design and construction of this project. Furthermore, Best Management Practices for Bridge Demolition and Removal will be followed. CONCLUSION Given the relatively minor amount of fill in wetlands proposed, there is not expected to be a significant impact to Essential Fish Habitat. No bents will be placed in the channel for either the temporary or permanent structures and no temporary or permanent fill will be placed in the channel. Furthermore, careful adherence to BMPs, adherence to species- specific moratoriums, and coordination with National Marine Fisheries staff will minimize, if not completely prevent, any adverse effects to EFH. Because the potential individual and cumulative effects will be minimal, mitigation is not proposed. ' AUG = ,. J ; MCF". z" EAD t j . FR? ®rg AUG 2 ,. COASTr,..

Project No. MABRZ-1509(4). REFERENCES: Categorical Exclusion (CE) prepared by NCDOT, dated April 25, 2000 This memo serves to update the previously submitted CE with respect to Threatened and Endangered Species. Plants and animals with federal classifications of Endangered (E), Threatened (T), Proposed Endangered (PE), and Proposed Threatened (PT) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. As of March 7, 2002, the U.S. Fish and Wildlife Service (USFWS) lists twelve federally-protected species for Onslow County as listed in Table 1. Bald eagle and golden sedge have been added since the completion of the CE. Descriptions of the protected species are provided in the referenced CE with the exception of the bald eagle and golden sedge. Biological conclusions of "No Effect" were given for these species. Suitable habitat does not exist for loggerhead turtle, piping plover, green sea turtle, leatherback sea turtle, eastern cougar, red-cockaded woodpecker, and seabeach amaranth. Suitable habitat does exist for rough-leaved loosestrife and Cooley's meadowrue, therefore, additional surveys were conducted on May 14, 2002 by NCDOT biologists Karen M. Lynch and Mary Frazer. Neither of these species was observed. Therefore, the biological conclusions rendered in the referenced CE of "No Effect" remain valid for these species. Brief descriptions of the characteristics and habitats for the bald eagle and golden sedge are given below as well as biological conclusions. Table 1.

Endangered is defined as a species that is threatened with extinction throughout all or a significant portion of its range. *Indicates a Historic record in which the species was last observed in Onslow County more than 50 years ago. Threatened due to Similarity of Appearance is a species that is threatened due to similarity of appearance with other rare species and is listed for its protection. These species are not subject to Section 7 consultation. Haliaeetus leucocephalus (bald eagle) Threatened Animal Family: Accipitridae Date Listed: March 11, 1967 Adult bald eagles can be identified by their large white head and short white tail. The body plumage is dark-brown to chocolate-brown in color. In flight bald eagles can be identified by their flat wing soar. Eagle nests are found in close proximity to water (within a half mile) with a clear flight path to the water, in the largest living tree in an area, and having an open view of the surrounding land. Human disturbance can cause an eagle to abandon otherwise suitable habitat. The breeding season for the bald eagle begins in December or January. Fish are the major food source for bald eagles. Other sources include coots, herons, and wounded ducks. Food may be live or carrion. Biological Conclusion: No Effect No large trees with a clear flight path to the water exist in the project area. There are no large bodies of water within one-half mile of the project area. Queen Creek is located approximately 1.0 mile downstream of Bridge No. 91. Suitable habitat for bald eagle does not exist with the project area. Furthermore, the project area was surveyed on May 14, 2002 by NCDOT biologists Karen M. Lynch and Mary Frazer and no bald eagles were observed. The North Carolina Natural Heritage Program (NHP) database indicated no record of bald eagle within 1.0 mile of the project area. Therefore,..project_ construction will not affect bald eagle. Lip; AUG ri.)l7( Carex lutea (golden sedge) Endangered ! 1 Sedge Family: Cyperaceae Date Listed: January 23, 2002 - ----? ?' ...-HEAD Golden sedge is a clump-forming member of the Sedge Family (Cyperaceae), with fertile culms (similar to stems) reaching 3 feet (1 m) or more in height. The yellowish- green leaves are long, narrow, and grass-like, with those of the culm mostly basal and to 11 inches (28 cm) long. Leaves of the vegetative shoots reach a length of 26 inches (65 cm). Fertile culms produce 2-4 flowering spikes, with the terminal spike male and the 1- 3 (usually 2) lateral spikes female and producing seeds. The beaks of the female fruit are pointed in diverse directions with the uppermost pointing up, middle beaks pointing to the side and lowermost pointing downwards. The leaf below the female fruit is also strongly reflexed or downward pointing. The fruits of this sedge are a stunning yellow-gold when mature, hence the specific epithet, lutea, which translates to "yellow-gold". Flowering spikes develop in early April with fruits maturing in mid-May and dropping by the end of June, restricting endangered species searches to this time period (May through June). Without the fruits present, leaves of Carex lutea are indistinguishable from many other sedges or grasses. This very rare endemic plant occurs only in Onslow and Pender Counties in NC and all eight populations discovered thusfar reside within a 12 mile area (5 populations in Pender County and 3 populations in Onslow County). This plant is found in areas where long leaf pine savannas grade into bottomland hardwood forests. These areas are somewhat shady to open with a dense herb layer. The typically acidic soils are comprised of sandy or peaty loam substrate with a higher than expected pH as these soils are underlain by a coquina limestone or marl formation. Soils remain wet to saturated in the spring. This habitat type is quite rare, therefore plants such as golden sedge that require this specific habitat are rare. Threats include fire suppression, which results in overcrowding, by woody vegetation. Habitat is also vulnerable to limestone mining. Drainage ditches at some sites have altered the depth and duration of soil saturation, and other sites have been altered by logging and tree-planting. (With care, canopy thinning can be beneficial to herbs stressed by shade and woody competition.) Habitat in powerline corridors is vulnerable to mowing during the growing season, and to herbicide application. Biological Conclusion: No Effect Suitable habitat in the form of long leaf pine savannas grading into bottomland hardwood forests does not exist in the project area. A survey was conducted on May 14, 2002 by NCDOT biologists Karen M. Lynch and Mary Frazer. No golden sedge was observed. A search of the NHP database indicated no record of golden sedge within 1.0 mile of the project area. Therefore, project construction will not affect golden sedge. A review of the North Carolina Natural Heritage Program (NCNHP) database on May 5, 2002 indicated that there are no known occurrences of any federally protected species within the project study area. Therefore, this project will not impact any federally protected species. If you have any questions or need additional information, please contact me at (919) 733-7844, extension 286. Cc: M.

Fisher: The Wilmington Regional Office received a copy of your application for the project known as B-3358 Onslow County Bridge #91 Replacement. Staff of the Wilmington Regional Office have reviewed the application for the applicability of the Stormwater Management rules to the proposed activity at this project. Based on our review, you do not appear to be proposing a development activity on this site at this point in time that would be subject to the stormwater requirements as provided for in 15A NCAC 2H,1000. Please be advised that other regulations will potentially apply to your proposed activities. If your project disturbs five acres or more and has a point source discharge 'of stormwater runoff, then it is subject to the National Pollutant Discharge Elimination System (N'PDES) stormwater discharge requirements. You are required to have an NPDES permit for stormwatcr discharge from projects meeting these critcria. This exemption applies only to the Coastal Stormwater Management Permit for the currently proposed activity, If at any time in the future, development of any part of this site is planned, as defined in NCAC 2H.1000, or if the proposed activities differ in any manner from what is shown on the plans on file with the Division, you must submit the project for review of the applicability of the stormwater management rules. If you have any questions concerning this matter, please do not hesitate to call me at (910) 395-3900.
