Wayne County SR 1920 Bridge No. 298 over Stoney Creek Federal-Aid Project BRM-5491(1) State Project No. 8.2330601 T.I.P. No. B-2660 Bridge No. 298 is included in the current Transportation Improvement Program. The location is shown in Figure 1. No substantial environmental impacts are anticipated. The project is classified as a Federal "Categorical Exclusion'. 1. SUMMARY OF ENVIRONMENTAL COMMITMENTS All standard procedures and measures including Best Management Practices will be implemented to avoid or minimize environmental impacts. No special or unique environmental commitments are necessary. II. SUMMARY OF RECOMMENDATIONS Bridge No. 298 will be replaced in its existing location as shown in Figure 2. It should be replaced with a new bridge having a bridge width of 44 feet from rail to rail and a length of 90 feet. The structure will provide a 36 foot travelway, two foot shoulders/gutters on each side, and a four foot minimum width sidewalk on the north side. The roadway grade of the new structure will be approximately the same as the existing grade at this location. The existing roadway will be widened to a 40 foot face to face curb and gutter section on the base approach and a 36 foot pavement with eight foot usable shoulders on the northwest approach. Traffic will be maintained on a temporary detour structure during construction of the replacement bridge. The estimated cost, based on current prices, is $447,000. The estimated cost of the project, as shown in the 1993-1999 Transportation Improvement Program, is $1,122,000. III. EXISTING CONDITIONS SR 1920 (Slocumb Street) is classified as an urban minor arterial in the Statewide Functional Classification System. Slocumb Street is also a minor thoroughfare on the Goldsboro Urban Area Thoroughfare Plan adopted on January 8, 1988. This minor arterial serves a suburban area of Goldsboro and serves as the back entrance to Seymour Johnson Air Force Base (SJAFB) in Wayne County (see Figure 1). The land use is wooded immediately surrounding r the bridge, with the guard house to SJAFB located 100 feet north. Stoney Creek Is the military reservation boundary for the base. On the west approach to the bridge, SR 1920 has a 22 foot pavement width with nine foot shoulders. The east approach is curb and gutter and flares out from the bridge so each direction of traffic flows around the guard house of the SJAFB entrance (see Figure 2 & 3). The vertical alignment is generally flat. The horizontal alignment is tangent at the bridge with a 0°45' curve approximately 540 feet to the north. The roadway is situated about 15 feet above the creek bed. The projected traffic volume is 6600 vehicles per day (VPD) for 1995 and 11900 VPD for the design year 2015. The volumes include 1 % truck-tractor semi-trailer (TTST) and 2% dual-tired vehicles (DT). However, SJAFB Engineering stated that in a few months the fuel distribution for the base will begin coming in by truck instead of by rail as it has in the past. Approximately 400,000 gallons of fuel per day will be trucked into the base over this bridge. This will result in 55 to 60 trucks (TTSTs) crossing the bridge twice a day during normal work hours. An increase in the traffic volume of an average of 115 TTST's per day will cross the bridge. The posted speed limit is 45 MPH traveling north from the bridge, and all traffic is required to come to a stop 100 feet south of the bridge. The existing bridge (see Figure 3) was built in 1955. The superstructure consists of a concrete floor on timber joists, and the substructure consists of bents constructed of timber caps on timber piles. The overall length of the bridge is 70 feet. Clear roadway width is 24.1 feet. The posted weight limit is 22 tons for single vehicles and 28 tons for TTSTs. Bridge No. 298 has a sufficiency rating of 34.5, compared to a rating of 100 for a new structure. One accident was reported on the bridge during the period from January 1, 1989 to December 31, 1991. There are no school buses using the bridge. The Mountains to Sea Trail crosses the north approach to the bridge paralleling the creek in this area. The trail is on private property in the project area. N. ALTERNATIVES There is only one reasonable and feasible alternative for replacing Bridge No. 298. This alternative is to provide an on-site detour on the north side of the existing bridge and to replace the bridge in the same location. Access to SJAFB at this site is crucial. In addition, SJAFB is widening and realigning the roadway approach on the base side. SJAFB officials requested the bridge be widened to accommodate two lanes of traffic entering the base. The two lane bridge causes a bottleneck at the guard house. Some vehicles can be waved through while others need to stop and be checked. A three lane bridge and 2 i approach will provide adequate storage for those vehicles being checked and a lane for those that are allowed to continue through to the base. A sidewalk was added to provide access for pedestrians who live off the base and walk each day, or for those whose rides typically drop them off before the bridge because they don't have an access pass onto the base. The 'do-nothing' alternative would eventually necessitate closure of the bridge. This is not desirable due to the traffic service provided by SR 1920. The Division Office concurs with the recommendation of an on-site detour during construction, and with the SJAFB officials request for widening the bridge to provide two lanes entering the base. One lane exiting the base is adequate. Investigation of the existing structure by the Bridge Maintenance Unit indicates that rehabilitation of the old bridge is not feasible due to its age and deteriorated condition. V. ESTIMATED COST The estimated costs of the alternative studied, based on current prices, are as follows: Structural Removal $8,400 Structure 190,000 Roadway Approaches 35,600 Detour Structure and Approaches 71,800 Miscellaneous & Mobilization 59,200 Engineering & Contingencies 60,000 ROW/Construction Easements/Utilities 22,000 TOTAL $447,000 SJAFB was contacted about participating in the funding of this project because of the additional lane they requested. They have no funds available at this time. VI. RECOMMENDED IMPROVEMENTS Bridge No. 298 will be replaced at its existing location with a new three lane structure having a length of approximately 90 feet. Minor improvements to the existing approaches will be necessary for a distance of about 100 feet on the SJAFB side, enough to tie to the existing curb and gutter. On the west approach improvements will be made for a distance of approximately 400 feet from the bridge. This includes widening for an additional lane on the south side to accommodate two lanes entering the base. This widening will occur for approximately 200 feet from the bridge and then taper back to the existing width in the next 200 feet. The Division Engineer concurs with this recommended alternate. A 40 foot face to face curb and gutter section will be provided on the base approach, and a 36 foot pavement with eight foot shoulders on the west approach. A 40 foot clear roadway 3 ti width is recommended on the replacement structure in accordance with the current NCDOT Bridge Policy. This will provide a 36 foot travelway with two foot shoulders/gutters and a four foot minimal width sidewalk on the north side of the structure. The three lane bridge will provide two lanes entering the base and one lane exiting. The design speed is 50 MPH. Based on preliminary studies, the Hydrographics Unit recommends a new structure length of approximately 90 feet. It is anticipated the elevation of the new structure will be approximately the same as the existing bridge. The length and height may be increased or decreased as necessary to accommodate peak flows as determined by further hydrologic studies. An on-site detour structure will be provided and will require a 3 @ 84' CMP temporary culvert located a minimum of 40 feet from the existing centerline to the detour centerline upstream (north) of the existing bridge. VII. NATURAL RESOURCES The project proposes to replace the bridge on SR 1920 spanning Stoney Creek in Wayne County, NC with a three-lane structure in the same location. Biologists visited the site on July 2, 1992 to verify documented information and gather field data to evaluate present conditions and assess potential impacts of the proposed activity. A subsequent visit to the site occurred on July 22 to ascertain if red-cockaded woodpeckers inhabit surrounding pine stands. From a northwest vantage point, the existing bridge crosses Stoney Creek at S 52 deg E, roughly at a right angle to the creek and forming four quadrants. The land immediately surrounding the current bridge in the project area is completely forested, except for the roadsides and the guard post at the entrance to Seymour Johnson Air Force Base. The `Mountains to the Sea Trail' traverses this site alongside Stoney Creek, crossing SR 1920 just north of the bridge. This investigation examined the vegetation surrounding the highway bridge on SR 1920 spanning Stoney Creek in Wayne County, NC, in order to (1) search for state and federally protected plant and animal species, (2) identify unique or prime-quality communities, (3) describe the current vegetation and associated habitats, (4) identify wetlands, and (5) provide information to avoid or minimize adverse environmental effects of the proposed bridge replacement project. Methods The project area was a circular plot with a radius of 200 feet. Plot center was located in the middle of the existing bridge. Plant communities within this plot were delineated from aerial photographs and ground-checked on site. Community types follow Schafale and Weakley (1990). Within each community, a list of member plant species and general site description was developed on-site. Dominance (fe/ac) of woody vegetation layers was determined by the variable plot method (Husch, Miller, and Beers 1972). Dominance (percent foliar cover) of herbaceous layers or communities was determined by ocular estimation, using foliar cover guides developed by Belanger and Anderson (1989). For communities dominated by trees, tree age, stem diameter at 4.5 feet above the ground (dbh), and total height were measured for the largest trees. Age was determined from 2-mm increment borings; dbh and height were 4 measured using d-tape dendrometers and Abney-level hypsometers, respectively (Wilson 1976). Ground distances were determined by measurements taken on aerial photographs, but all other measurements were developed from on-site reconnaissance. Evidence of terrestrial and aquatic wildlife was sought on-site through close observation of all available signs. Habitats were characterized based on plant communities, and typical wildlife communities associated with these habitats were determined. Special attention was given to features indicative of habitat for species listed as threatened, endangered, or special concern. Aquatic system features were noted at three locations on the site: at the bridge and 100 ft upstream and downstream of the existing structure. Available documentation of water quality was reviewed. Wetland determinations followed procedures described by the Corps of Engineers Wetland Delineation Manual (Environmental Lab. 1987). Biotic Communities Plant Communities One natural plant community occurs within the study area, Coastal Plain Bottomland Hardwoods (Blackwater Subtype). Compared to forest community groupings of the Society of American Foresters (1967), the Coastal Plain Bottomlands Hardwoods community is comparable to Type 82, Loblolly Pine-Hardwood. In addition, two rooted-aquatic species, ludwigia Ludwi is sp.) and bushy-pondweed Naas sp.), occur as scattered individuals in Stoney Creek. Owing to their relatively low density, they are considered part of the bank-to-bank wetland of the creek, and no separate aquatic community is recognized. In the project area, the Coastal Plain Bottomland Hardwood community occurs on well-drained to moderately well-drained soils. Water-level of the creek is generally about 3 feet below the general surface of the bottomland, and most of the project area is therefore non-wetland. The only exceptions are: (1) a small slough about 300 fe in area, located about 100 feet north (upstream) of the current bridge; and (2) a 3 x 40-feet drainage ditch, located parallel to the road about 10 feet north of the existing bridge, that empties into Stoney Creek. Both of these areas are wetlands, but for convenience they are included within this community owing to their small size The upper canopy contains loblolly pine (Pinus taeda), sweetgum (Uguidambar styraciflua), red maple (Acer rubrum), water oak (Quercus nigra), willow oak (Quercus phellos), laurel oak (Quercus laurifolia), southern red oak (Quercus falcata), ash Fraxinus sp.), persimmon (Diospyros virginiana), river birch (Betula nigra), and blackgum (Nyssa sylvatica). The largest trees are loblolly pines, 50 years old, 28-inches dbh, and 85 feet tall. Basal area for canopy species equals 130 ft2/acre; loblolly pines provide the most basal area, 70 ft2/acre. Red maple provides 20 ft2/acre, the various oaks provide 10 fe/ac, and the remaining species provide the remaining 30 ft2/acre. Stand quality is moderately high, especially north of the bridge. The lower canopy contains American hombeam (Carpinus caroliniana), titi (Cyrilla racemiflora), and possumhaw (Ilex decidua). The shrub layer contains blueberry (Vaccinium elliottii), elderberry (Sambucus canadensis), pinxter (Rhododendron nudiflorum), and small-flowered pawpaw (Asimina parviflora). The ground layer contains few species, mostly woody, poison ivy (Toxicodendron radicans), trumpet creeper (Campsis radicans), Japanese honeysuckle 5 (Lonicera iaponica), greenbrier (Smilax rotundifolia and S. bona-nox , muscadine itis rotundifolia), panic grass Panicum sp.), sedge Carex sp.), pokeweed (Phytolacca americans), Virginia creeper (Parthenocissus guinguefolia), yellow jessamine (Gelsemium sempervirens), St. Andrew's-cross (Hypericum hypericoides), giant cane (Arundinaria i antea , and uniola grass (Uniola laxa). Foliar cover of the ground layer averages 30 percent, although it is somewhat greater north of the existing bridge. Poison ivy provides 30 percent of this total; greenbrier and giant cane, 20 percent each; Japanese honeysuckle, 10 percent; and the remaining ground-layer species more-or-less equally share the remaining 20 percent. Wildlife (General) The mixed hardwood and pine forest surrounding the project area provides a rich habitat for a variety of Coastal Plain wildlife species, especially avian and terrestrial mammal populations. Raccoon and deer tracks were noted in several locations throughout the bottomland surrounding the project site. Numerous den trees and snags are scattered throughout the forest. Hairy Woodpeckers Picoides villosus were observed foraging in the pine trees located on the base, southwest of the bridge, and a number of common songbird species were sighted and heard in the canopy. A Barred Owl (Strix varia) was found dead on the roadside, reportedly hit by a vehicle the evening before. This species is a good indicator of mature forest habitat, and its presence suggests that ample small mammal prey species are available. The aquatic resource is in relatively good condition as evidenced by mussels Corbicula flumenia , which were found to be abundant in the creek's gravel and sand substrate at all three sampling locations. Fish (unidentified) were observed upstream in Stoney Creek. A Boy Scout wildlife observation trail with interpretive signs, benches, and picnic sites exists in the southeast quadrant, where it accesses several different habitat types in a fairly compact area. Physical Resources Soil Geologically, the entire project lies on the Black Creek Formation, Cretaceous-aged sediments of clay and fine-grained micaceous sand in the Coastal Plain physiographic region (Brown 1985). Topography in the vicinity of the project site ranges in elevation from a low of about 50 feet along the nearby Neuse River to a high of 112 feet. Soil within the project area is mapped as Bibb sandy loam (Barnhill et al. 1974), which is listed as a hydric soil. Field observations confirm that the soil on site is poorly drained and experiences frequent flooding (See Wetland discussion). 6 Water Stoney Creek arises northeast of Goldsboro in north central Wayne County, from whence it flows southwest to join the Neuse River, approximately one mile downstream of this crossing. At this location Stoney Creek flows through a mixed hardwood/pine forested palustrine habitat. The creek meanders considerably across the floodplain and has apparently changed course throughout history. The water classification of Stoney Creek is C, suitable for fish propagation and agricultural purposes, but not rated for human consumption (NCDEM 1989a). An abundance of mussels Corbicula fluminea found in the streambed and fish observed in several sections of the stream suggest that the condition of the water in Stoney Creek is fairly good. As noted in Table 1, the water is clear, with a sand and gravel bottom. No Benthic Macroinvertebrate Ambient Network (BMAN) site exists on Stoney Creek, and the nearest site, located at the SR 1915 crossing of the Neuse River ('Good' rating) is upstream of Stoney Creek's confluence with the Neuse (NCDEM 1989a, 1991). Table 1. Stream Characteristics Observed At Stoney Creek Crossing. ---F Observation Point upstream Existing Downstream Substrate Sand and gravel Current Flow Moderate Channel Width (ft) 15.0 12.0 20.0 Bank Height (ft) 3.5 2.5 6.0 Water Depth (ft) .75 2.0+ 1.0 Water Color Clear Water Odor None Aquatic Vegetation None Yes None Adjacent Vegetation Hardwoods Weeds Hardwoods Wetlands Associated Sloughs to North Intermittent Drain None Observed Jurisdictional Topics Wetlands As noted above, the site is underlain by Bibb sandy loam, a poorly drained hydric soil subject to frequent flooding. In fact, extensive areas upstream from the bridge and its approaches show evidence of overland flow, ponding, and vegetation tolerant of extended periods of soil saturation. River birch and other bottomland hardwood species dominate the forest canopy except in drier spots where large diameter pines dominate. 7 An ephemeral seepage ditch occurs about 25 feet upstream of the bridge and runs parallel to the existing road; rush, smartweed, and panic grass occupy this ditch, and the soil yielded a Munsell Soil Color of 5Y 3/1. Farther north of the bridge, slough-like depressions surrounded by large diameter trees occur where it appears stream channel changes have historically occurred. Beyond the project limits cane dominates areas of the shrub layer. Immediately downstream of the bridge, no wetland conditions occur; however, at farther distances, sloughs and wet drainage depressions were noted. The proposed project will not permanently impact any wetlands. However, the temporary detour will fill the upstream seepage ditch, previously described, during construction. The wetland area temporarily filled is approximately 150 square feet. The ditch and wetlands will be reconstructed when the detour is removed. Protected Species Under federal law, any federal action which is likely to result in a negative impact to federally protected plants and animals is subject to review by the US Fish and Wildlife Service (USFWS) under one or more provisions of the Endangered Species Act (ESA) of 1973. In the case of state-funded action, where federal wetland permits are likely to be required, for example, the USFWS can require consultation to insure that the proposed action does not jeopardize any endangered, threatened or protected species. Even in the absence of federal actions, the USFWS has the power, through provisions of Section 9 of the ESA, to exercise jurisdiction on behalf of a protected plant or animal. The USFWS and other wildlife resource agencies also exercise jurisdiction in this resource area in accordance with the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 USC 661 et seq). North Carolina laws are also designed to protect certain plants and animals where statewide populations are in decline. Federally Listed Species The US Fish and Wildlife Service has identified the federally listed species shown in Table 2. Habitat requirements and available records concerning all of these species have been reviewed, and conditions at the bridge site have been examined in light of species requirements. More specifically, following Table 2, the investigators have evaluated whether habitat exists in the project impact area for federally-listed species in this county and, if existing, whether habitat is being used by the species. Table 2. Federally Listed Species Potentially Occurring in Wayne County. Species Status* Distribution Red-cockaded Woodpecker Picoides borealis E Eastern NC *E= endangered; T= threatened; CH= critical habitat determined; P= proposed; SA=status due to similarity of appearance to another species. Red-cockaded woodpecker Picoides borealis Throughout southern and eastern North Carolina the potential exists for red-cockaded woodpeckers Picoides borealis , an endangered species, to colonize pine stands of sufficient 8 age and with certain attributes. Because a number of pines greater than 30 years old would be removed during the proposed construction (see Impacts Section), an examination of contiguous stands to a radius of one-half mile was conducted to ascertain whether red-cockaded woodpecker colonies exist proximal to the project site. The examination was conducted following procedures consistent with US Fish and Wildlife Service guidelines (Henry 1989). Only one stand where pines exceeded 50 percent of the basal area was found to be age 60 years or older. An increment boring determined that a specimen tree with 28' DBH is age 68. In this stand, located approximately 750 feet southwest of the bridge, between the power-line right-of-way and the railroad spur line, all pine trees were examined. Neither cavity holes nor evidence of excavation activity to create cavity holes was observed in any living pine trees. All other pine-dominated stands were visited and through increment borings determined to be no more than 55 years old, with most in the 40-45 or 50-55 year age classes. These scattered stands comprise clusters of pines within the more prevalent hardwood-pine forest. In most of the surrounding forest, hardwoods either numerically dominate stand composition or occur exclusively. East of the bridge, where the highest pine densities occur, the trees are mostly in the 20-30 year old age class. Except for in this young pine stand, understory hardwood encroachment in the pine canopy is fairly extensive, a result of no past management activity to control competition. This investigation confirmed that red-cockaded woodpeckers do not currently inhabit the vicinity and that removal of pines greater than thirty years old would have no adverse effects. State Listed Species: According to Steve Hull, NC Natural Heritage Program, no species listed by the state Of North Carolina as endangered, threatened, or special concern have been recorded in the vicinity of this bridge crossing. No evidence was found on this site to suggest that any of the species listed in North Carolina occur here. Unique and/or Prime-Quality Habitat. The Coastal Plain Bottomland Hardwoods community cannot be considered unique since it occurs commonly in Wayne County. Although the stand in the project area is of good quality, it is not prime-quality. Thus, no adverse impact to unique or prime-quality forest communities is expected from this project. Impacts The proposed project will replace an existing bridge with a wider structure adding one lane at the same location. Since access to Seymour Johnson Air Force base cannot be interrupted, an on-site detour is necessary, and no other alternative exists for construction at this site. The on-site detour is proposed to be located upstream of the bridge, with a centerline approximately 35 feet from the centerline of the existing structure. Including pavement and fill slopes, the detour structure will require clearing and filling to a distance about 50 feet upstream from the existing bridge. Thus, a rectangular area of forest measuring about 50 x 325 feet, or 0.4 acre, must be cleared to accommodate the detour. A detour downstream of the current bridge would require an even greater distance, hence more clearing. 9 The clearing necessary for the detour would remove 25 to 30 large loblolly pines greater than 30 years old. Such proposed removal of the pines necessitated a survey of the surrounding area for evidence of red-cockaded woodpecker colonies (as discussed), but none were found. Therefore, no impact will result from removal of these trees. In addition to the clearing and temporary detour structure, additional highway modification will be needed for approaches to the new wider structure, which will tie into the existing road at a distance of 400 feet north. This wider approach will mostly occur on land currently cleared of forest cover and within the area where vegetation is periodically controlled. After the new bridge is constructed and the temporary detour removed, area cleared for the temporary detour would naturally regenerate to the existing plant community type, which is mixed pine and hardwood. No change in the site's hydrology is likely to occur because of these temporary alterations, and relatively little long-term change in wildlife habitat will occur as a result of construction activity. Sufficient habitat exists adjacent and surrounding the site to accommodate all species that would be dislocated during the project activity. Within Wayne County as a whole, loblolly pine dominated stands occupy 32,149 acres, 22 percent of the total forest area and 9 percent of the entire county (Johnson 1990). Since 1984, regional forest cover for the 21-county Southern Coastal Plain region of North Carolina has decreased only 1 percent (Johnson 1990). Therefore, since no permanent forest loss is required by this project, since the temporary losses are small and come from a common forest community, and since forest cover has remained essentially constant in the region, no adverse impact to the forest cover is expected by the proposed project. Accelerated soil erosion is always a concem when building around streams. Erosion contributes to soil loss, but equally importantly, erosion sediments are deposited downstream. In sufficient quantities, these deposits clog and restrict drainage and smother aquatic organisms, especially bottom-dwelling and bottom-reproducing species. But soil erosion is largely avoidable, if appropriate measures, consistent with current Best Management Practices, are taken to control erosion during construction. The mussels identified at this location are exotic species known to tolerate and recover quickly from disturbance. Following and monitoring standard control practices should be sufficient. The proposed project will not permanently impact any wetlands. However, the temporary detour will fill the upstream seepage ditch, previously described, during construction. The wetland area temporarily filled is approximately 150 square feet. The ditch and wetlands will be reconstructed when the detour is removed. Permit Coordination In accordance with provisions of Section 404 of the Clean Water Act (33 U.S.C.O.E. 1344), a permit will be required from the U.S. Army Corps of Engineers for the discharge of dredged or fill material into 'Waters of the United States! Since the subject project is classified as a categorical exclusion and since less.than one acre of wetlands will be impacted by the project, it is likely that this project will be subject to the Nationwide Permit Provisions of 33 CFR 330.5 (A) 23. This permit authorizes any activities, work and discharges undertaken, assisted, authorized, regulated, funded or financed, in 10 whole or in part, by another federal agency and that the activity is 'categorically excluded' from environmental documentation because it is included within a category of actions which neither individually or cumulatively have a significant effect on the environment. However, final permit decisions are left to the discretionary authority of the United States Army Corps of Engineers. A 401 Water Quality Certification, administered through the NC Department of Environment, Health and Natural Resources, will be required. This certificate is issued for any activity which may result in a discharge into waters for which a federal permit is required. Compensatory mitigation is not required under a Nationwide Permit. Erosion and sedimentation control measures should be strictly enforced during construction activities to minimize unnecessary impacts to stream and wetland ecosystems. Best Management Practices will also be implemented. Literature Cited Barnhill, W.L., R. A. Goodwin, Jr., M.R. Bostian, N.A. McLoda, G. W. Leishman, and R. J. Scanu. 1974.

Book Stores, Inc., Corvallis. Pp. 183. VIII. ENVIRONMENTAL EFFECTS The project is expected to have an overall positive impact. Replacement of the inadequate bridge will result in safer traffic operations. The project is considered to be a Federal 'Categorical Exclusion' due to its limited scope and insignificant environmental consequences. The bridge replacement will not have an adverse effect on the quality of the human or natural environment with the use of current NCDOT standards and specifications. The project is not in conflict with any plan, existing land use, or zoning regulation. No significant change in land use is expected to result from construction of the project. No adverse impact on families or communities is anticipated. Right of way acquisition will be limited. No relocatees are expected with implementation of the proposed alternative. No adverse effect on public facilities or services is anticipated. 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. This project is subject to compliance with Section 106 of the National Historic Preservation Act of 1966, as amended, implemented by the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codified at 36 CFR Part 800. Section 106 requires that if a federally funded, licensed, or permitted project has an effect on a property listed on or eligible for the National Register of Historic Places, the Advisory Council on Historic Preservation be given an opportunity to comment. The area of potential effect (APE) was surveyed and is shown on Figure 2. The bridge, built in 1955, and the modem guardhouse, are the only structures located within the APE. 12 Since there are no properties either listed on or eligible for the National Register within the APE, no further compliance with Section 106 is required. The State Historic Preservation Officer has reviewed the archaeological aspects of the project and determined that an intensive survey will not be required. The Farmland Protection Policy Act requires all federal agencies or their representatives to consider the potential impacts to prime and important farmland soils by all land acquisition and construction projects. Prime and important farmland soils are defined by the U. S. Soil Conservation Service (SCS). The SCS was asked to determine whether the proposed project will impact farmland soils and if necessary, to complete Form AD-1006, Farmland Conversion Impact Rating. The completed form is included in the Appendix. According to the SCS, the proposed project will impact 0.125 acres of soils defined as prime and statewide or local farmland soils. This accounts for very little of the 275,280 acres of prime or important soils found in Wayne County. The impact rating determined through completion of Form AD-1006 indicates that the site's assessment and relative value score is 32.5 out of a possible 260. A higher score would indicate that mitigation should be considered. It can be concluded that the project's impact on farmland, as defined by the SCS, is minimal and therefore, no mitigation is proposed. The project is located within the Southern Coastal Plain Air Quality Control Region. The ambient air quality for Wayne County has been determined to be in compliance with the National Ambient Air Quality Standards. Since this project is located in an area where the State Implementation Plan (SIP) does not contain any transportation control measures, the conformity procedures of Title 23, Code of Federal Regulations (CRF), Part 770 do not apply to this project. The project will not substantially increase traffic volumes. Therefore, its impact on noise levels and air quality will be insignificant. Noise levels could increase during construction but will be temporary. 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. This evaluation completes the assessment requirements of Title 23, Code of Federal Regulations (CFR), Part 770 and 772 and no additional reports are required. An examination of records at the North Carolina Department of Environment, Health and Natural Resources, Division of Environmental Management, Groundwater Section and the North Carolina Department of Human Resources, Solid Waste Management Section revealed no underground storage tanks or hazardous waste sites in the project area. Wayne County is a participant in the National Flood Insurance Regular Program. The approximate 100-year floodplain in the project area is shown in Figure 4. The amount of floodplain area to be affected is not considered to be significant. 13 There are no practical alternatives to crossing the floodplain area. Any shift in the alignment would result in a crossing of about the same magnitude. The alignment of the project is perpendicular to the floodplain area. All reasonable measures will be taken to minimize any possible harm. On the basis of the above discussion, it is concluded that no serious adverse environmental effects will result from implementation of the project. 14 ft7 Rertrgnl ? Errn?! ?.

Project BRZ-1403(2), State Project 8.2320401, B-2154 We have reviewed the draft reports as prepared by DSA Design Group of Raleigh, NC, for the replacement of Bridge No. 298 on SR 1920 in Wayne County and Bridge No. 79 on SR 1403 in Nash County. These reports are as discussed with Mr. Keith D. Lewis, PE, and James H. Hoskins, PE, at their on-site review; therefore, we are in agreement with the recommendations contained in the draft reports and concur with the improvements and detours noted. The one exception that was not mentioned in the draft report for Bridge No. 79 on SR 1403 is we had recommended the new bridge be shifted in a northwesterly direction as Sandy Creek is migrating in that direction and is at present undermining the end bent.

Marley, Jr., P.E. State Highway Administrator NC Department of Transportation P. 0. Box 25201 Raleigh, NC 27611 Dear Mr Marley _ It has come to my attention that the Slocumb Street bridge (TIP #B-2660, SR 1920 over Stoney Creek, Wayne County) is scheduled for replacement. The bridge adjoins the base property and Slocumb Street is one of our 24-hour base entrances. We currently have a construction project under contract that widens Slocumb Street on the base side of the bridge to four lanes. Based on the existing road geometry, the gate proximity to the bridge, and the projected increase in truck traffic, request the bridge be widened to at least four lanes. This would ensure that the new bridge aligns with our street improvements and provides adequate site distance for motorists as they approach our gate. Your assistance on this matter will be appreciated. My point of contact is Mr Dennis Goodson at telephone number (919) 736-5514. Sincerely M. HORNBURG, Colonel, SAF cc: Mr James A. Bissett, Jr., P.E.

Ward, P.E., Manager Planning and Environmental Branch Division of Highways North Carolina Department of Transportation Post Office Box 25201 Raleigh, North Carolina 27611-5201 Attention: Mr. Doug Huggett % Dear Mr. Ward: Reference your written request of March 29, 1993, for Department of the Army authorization to replace Bridge No. 298 over Stoney Creek on SR 1920, in Goldsboro, Wayne County, North Carolina. Your Categorical Exclusion document indicates that the proposed project will not permanently impact any wetlands. For the purposes of the U.S. Army Corps of Engineers' Regulatory Program, Title 33, Code of Federal Regulations (CFR), Part 330.6, published in the Federal Register on November 22, 1991, lists nationwide permits (NWP). Authorization, pursuant to Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act, was provided for activities undertaken, assisted, authorized, regulated, funded or financed, in whole or in part, by another Federal agency or department where that agency or department has determined, pursuant to the CEQ Regulation for the Implementing the Procedural Provisions of the National Environmental Policy Act, 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 the office of the Chief of Engineers has been furnished notice of the agency's or department's application for the categorical exclusion and concurs with that determination. Your work on the bridge replacement is authorized by this nationwide permit provided it is accomplished in strict accordance with the enclosed conditions. This nationwide permit does not relieve you of the responsibility to obtain any required State or local approval. You should contact Mr. John Dorney, telephone (919) 733-1786, regarding water quality certification. -2- The document also states that a temporary detour will be required upstream of the existing bridge, impacting approximately 150 square feet (0.003 acre) of wetlands. Temporary detour fills are incidental to the primary construction and not covered by the Categorical Exclusion (49 CFR 771.117). This portion of the project may be considered under Nationwide Permits (NWPs)l 4 (Road Crossings) or 33 (Temporary Construction, Access and Dewatering), or by General Permit No. 31 (Associated fills including detour fills). The NWPs will require pre-discharge notification. Thank you for your time and cooperation.
