A-5 Caldwell County Bridge No. 40 on SR 1552 Over Kings Creek Federal Aid Project BRZ-1552(4) State Project 8.2731901 TIP Project B-2525 Bridge Number 40 has been included in the Federal Aid Bridge Replacement Program. The location of Bridge Number 40 on SR 1552 over Kings Creek is shown in Figure 1. No substantial environmental impacts are anticipated as a part of this project, therefore, the proposed project is considered to be a "categorical exclusion" as defined by the Federal Highway Administration's environmental guidelines (23 CFR 771.117). 1. SUMMARY OF ENVIRONMENTAL COMMITMENTS In order to minimize impacts to water resources at the project site and receiving waters downstream, NCDOT's Best Management Practices for the Protection of Surface Waters and Sediment Control Guidelines will be strictly enforced during the construction of the proposed project. Construction is likely to be authorized by provisions of the United States Army Corps of Engineers' General Nationwide Permit 33 CFR 330.5 (a)(23). Since Kings Creek is designated as a trout stream, this project must be reviewed and approved by the North Carolina Wildlife Resources Commission prior to the issuance of the Nationwide Permit. Also, the proposed project will require a Section 401 Water Quality General Certification from the Division of Environmental Management (DEM) prior to the approval of Section 404 authorization. II. PROJECT STATUS The proposed project is included in the North Carolina Department of Transportation's 1995-2001 Transportation Improvement Program (TIP). The 1995-2001 TIP includes $ 20,000 for right of way acquisition in fiscal year 1995 and $ 625,000 for construction in fiscal year 1996 for a total funding of $ 645,000. The proposed project is funded with bridge replacement funds for bridges that are not on the Federal Aid System. Cost estimates for the proposed project were updated during the planning process. Currently, the total cost of the project is anticipated to be $810,000. This estimate includes $775,000 for construction and $35,000 for right of way acquisition. III. SUMMARY OF RECOMMENDATIONS Bridge Number 40 on SR 1552 (Grandin Road) over Kings Creek in Caldwell County will be replaced at its existing location with a bridge 55 m (180 feet) in length (see Alternative 1 in Figure 2). A temporary detour bridge 23 m (75 feet) in length located 10 m (30 feet) north of the existing bridge is also recommended. Both the permanent bridge and the 2 temporary detour structure will have clear roadway widths of 7.9 m (26 feet) in order to provide for two 3.4 m (11-foot) lanes and 0.6 m (2-foot) shoulders. Temporary construction easements will be needed on the north side of the bridge to contain the proposed temporary on-site detour, which will be approximately 137 m (450 feet) in length. Please note that the bridge lengths specified in this report may be increased or decreased once more detailed hydrologic analyses are done during final design. Replacing Bridge Number 40 in its existing location will maintain the 0.4 km (0.25 mile) tangent section on SR 1552 in the vicinity of the bridge, and the proposed temporary on-site detour will enable the bridge to be replaced with little or no inconvenience to the motoring public. A 60 mph design speed will be used to design the bridge. A cleanout of the bridge opening just upstream (south) of the existing bridge is recommended to ensure optimum flow conveyance under the proposed bridge. Placing riprap on the west channel bank south of the bridge for a length of 50 m (160 feet) is also recommended to eliminate further erosion of the bank and to protect the end bent of the bridge from scour. The roadway approaches to the bridge will also be improved to tie the existing roadway to the proposed bridge. The roadway will be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge. IV. EXISTING CONDITIONS A. Roadway SR 1552 in Caldwell County is classified as a rural local route in the Statewide Functional Classification System and is not part of the Federal Aid System. Near Bridge Number 40 over Kings Creek, SR 1552 has a 4.9 m (16-foot) wide travelway with 1.2 m (4-foot) grassed shoulders. In the vicinity of the bridge, both the vertical and horizontal alignments of SR 1552 are good. Bridge Number 40 lies on a 0.4 km (0.25 mile) tangent section of SR 1552. Photographs of the approaches to the existing bridge are shown in Figure 3. The statutory 55 mph speed limit is enforced along SR 1552. B. Traffic Volumes In the construction year 1996, the average daily traffic on SR 1552 is anticipated to be 400 vehicles per day. In 2016, the traffic volume on SR 1552 is expected to increase to 700 vpd. The projected traffic volume includes 1% truck-tractor semi-trailers and 2% dual-tired vehicles. Three school buses cross Bridge Number 40 on SR 1552 twice daily. 3 C. Existing Structure The existing bridge was constructed in 1966. The superstructure consists of timber flooring on 1-beams and timber joists. The substructure consists of concrete encased timber posts and piles. The overall length of the existing bridge is 42.4 m (139 feet) and the clear roadway width is 5.8 m (19 feet). The structure is situated 5.5 m (18 feet) over the bed of Kings Creek. Presently, the posted weight limit is 10 tons for single vehicles and 18 tons for trucks with trailers. The sufficiency rating for Bridge Number 40 is 16.0, compared to a rating of 100 for a new structure. The estimated remaining life of Bridge Number 40 is two years. Figure 3 includes a photograph of the existing structure. i- D. Accidents No accidents were reported in the vicinity of Bridge Number 40 during the time period from August 1, 1990 through July 31, 1993. E. Utilities The proposed project will have a low impact on utilities. An underground telephone cable owned by Southern Bell lies along the north side of SR 1552. This cable will require relocating. V. ALTERNATIVES STUDIED Three alternatives for replacing Bridge Number 40 on SR 1552 were studied. All of the design alternatives utilize a 60 mph design speed. Each alternative is shown in Figure 2 and described below. Alternative 1 (recommended) will replace the bridge at its existing location with a bridge 55 m (180 feet) in length. A temporary detour structure 23 m (75 feet) in length will be provided 10 m (30 feet) north of the existing bridge. Both the permanent structure and the temporary detour structure will have clear roadway widths of 7.9 m (26 feet). A temporary on-site detour approximately 137 m (450 feet) in length will be constructed on the north side of SR 1552. This temporary detour will have a 25 mph design speed. This alternative will retain the existing 0.4 km (0.25 mile) tangent section on SR 1552 in the vicinity of the bridge. The roadway approaches to the bridge will also be improved as a part of this alternative. The roadway will be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge making the project length 146 m (480 feet). Alternative 2 would replace Bridge Number 40 on new location. A bridge 55 m (180 feet) in length would be constructed approximately 10 m (30 feet) north of the existing bridge. This structure would have a clear roadway width of 7.9 m (26 feet). SR 1552 would be realigned on the north side of the existing roadway from the existing curve east of the bridge to approximately 305 m (1000 feet) west of the bridge, a length of 0.49 km (0.30 mile). This alternative would introduce two additional curves into the alignment of SR 1552 in the vicinity of the subject bridge. This alternative would allow motorists to continue using the existing bridge while the new bridge and roadway are constructed. 4 Alternative 3 would replace the bridge at its existing location with a bridge 55 m (180 feet) in length with a 7.9 m (26-foot) clear roadway width. The road would be closed for approximately 9 months during construction, and traffic would be detoured onto other (unpaved) secondary roads in the area (see Figure 1). Detouring traffic off-site is discussed further in Section VII. The roadway approaches to the bridge would also be improved as part of this alternative. The roadway would be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge, making the total project length 146 m (480 feet). Both rehabilitation of the existing bridge and the "do nothing" alternative were considered early in the project study, but were eliminated from consideration. Due to the existing bridge's poor condition, rehabilitating the existing structure is not feasible. The "do nothing" alternative would eventually necessitate closure of the bridge and would thereby eliminate the traffic service provided by SR 1552. VI. COST ESTIMATES Construction and right of way cost estimates for the studied alternatives are presented below. Contract Cost Engineering and Contingencies Total Construction Cost Right of Way and Utilities Total Cost of Alternative Alt. 1 Alt. 2 Alt. 3 $ 675,000 $ 660,000 $ 358,000 $ 100,000 $ 100,000 $ 67,000 $ 775,000 $ 760,000 $ 425,000 $ 35,000 $ 50,000 $ 31,500 $ 810,000 $ 810,000 $ 456,500 * Note: The costs shown for Alternative 3 do not include the costs of upgrading unpaved secondary roads in the project area. This upgrading would be required in order to provide an adequate off-site detour (see Section VII). In addition, these costs do not include the additional road user costs that would result from increased travel distances. VII. OFF-SITE TRAFFIC DETOUR Traffic will be maintained on-site during the replacement of Bridge Number 40 on SR 1552. SR 1552 serves as a connector between NC 18 and NC 268 in northeastern Caldwell County (see Figure 1). No other paved roads which connect NC 18 and NC 268 are located in the northeastern 5 11 portion of the county. Road closure during replacement of the subject bridge would greatly inconvenience school bus traffic, as well as local farmers, who regularly cross Bridge Number 40. If the road were closed during the replacement of Bridge Number 40, approximately 1 mile of additional travel would be required for through traffic. All traffic which currently crosses Bridge Number 40 would have to travel on SR 1511 (Howell Farm Road) and SR 1551 if SR 1552 were closed during bridge construction. SR 1511, is an unpaved, narrow roadway with limited sight distance. The roadway has a high number of curves and has several steep cut and fill slopes immediately adjacent to the roadway. Traffic moving from SR 1510 (Tom Dula Road) to SR 1573 (Howell Farm Road) would be required to travel an additional 13.8 km (8.6 miles) as a result of road closure at the bridge. Improvements to SR 1511 (realignment and paving) would be required before that route could be used as a temporary detour. SR 1511 is not anticipated to be paved before the bridge is replaced. Improvements to SR 1511 would be expensive and more damaging to the environment than the temporary detour and structure proposed under Alternative 1, since SR 1511 parallels Little Kings Creek for most of its length. In conclusion, SR 1511 is not suited to accommodate detour traffic from SR 1552, and improvements to SR 1511 would be more environmentally damaging and expensive than the recommended on-site detour. It is anticipated that the cost of realigning and paving SR 1511 would exceed the cost of constructing the recommended on-site temporary detour. Therefore, the recommended on-site temporary detour is preferred to detouring traffic off-site. VIII. RECOMMENDED IMPROVEMENTS Alternative 1 (see Figure 2) is recommended for replacing Bridge Number 40 on SR 1552 over Kings Creek. This alternative calls for replacing the bridge at its existing location with a bridge 55 m (180 feet) in length. A temporary detour bridge 23 m (75 feet) in length located 10 m (30 feet) north of the existing bridge is also recommended. Both the permanent structure and the temporary detour structure will have clear roadway widths of 7.9 m (26 feet). Temporary construction easements will be needed on the north side of SR 1552 to contain the proposed temporary on-site detour. A 60 mph design speed will be used to design the permanent bridge and approaches. A 25 mph design speed will be used for the temporary detour. Replacing Bridge Number 40 in its existing location will maintain the 0.4 km (0.25 mile) tangent section on SR 1552 in the vicinity of the bridge. The roadway approaches to the bridge will also be improved. The roadway will be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge. Also as a part of the proposed project, a cleanout of the bridge opening just upstream (south) of the existing bridge is proposed to ensure optimum flow conveyance. Debris under the existing bridge caused a 6 sediment buildup just upstream of the existing bridge and created a meander in Kings Creek. The sediment buildup has limited the existing bridge's flow conveyance. In order to eliminate further erosion, the west stream bank on the south side of the proposed bridge will be riprapped for a length of 50 m (160 feet). An on-site temporary detour will be provided. This detour will enable the existing bridge to be removed and replaced with little or no inconvenience to the motoring public. As described in Section VII., if SR 1552 were closed during bridge construction, motorists would have to use SR 1511, an unimproved road, to travel through the area. The cost of improving SR 1511 in order to make it suitable for traffic from SR 1552 would be more expensive than the recommended temporary on-site detour. Alternative 1 is considered to be the best alternative. Alternative 1 maintains the existing horizontal alignment and maintains traffic on-site. Alternative 1 causes the least inconvenience to the motoring public and has fewer environmental impacts than Alternative 2. IX. ENVIRONMENTAL IMPACTS A. Prime and Important Farmland The Farmland Protection Policy Act of 1981 (FPPA) requires all federal agencies to consider the impact of land acquisition and construction projects on prime and important farmland soils. These soils are designated by the United States Soil Conservation Service (SCS). In compliance with the Act, the SCS was asked to review the proposed bridge replacement project and determine whether any farmland soils will be impacted. The SCS did not respond within the 45 day review period established by FPPA regulations; therefore, the Farmland Protection Policy Act of 1981 (FPPA) does not apply to this project. B. Historic and Cultural Resources 1. Historic Architectural Resources 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 general project area was reviewed in the field by North Carolina Department of Transportation staff. The North Carolina Department of Transportation and the State Historic Preservation Office (SHPO) met on November 16, 1993 to discuss the project. The North Carolina Department of Transportation provided project area photographs and aerial photographs and reviewed them with SHPO. Grandin Baptist Church is the only property over fifty years old within the general project area. This property is located on SR 1573 (Howell Farm Road) south of SR 1552 (see Figure 2). 7 In a letter dated December 30, 1993, SHPO offered their preliminary comments. In terms of historic architectural resources, they were aware of the presence of Grandin Baptist Church in the general project area. A copy of this SHPO letter is included in the Appendix (see pages A-1 and A-2). On March 1, 1994, North Carolina Department of Transportation staff showed SHPO staff the tax parcel map for Grandin Baptist Church. The church property is not contiguous with SR 1552 (Grandin Road) or with Bridge Number 40 and therefore is not within the project's area of potential effect. North Carolina Department of Transportation and SHPO are in agreement that there are no properties within the project's area of potential effect that are either listed in or eligible for the National Register; therefore, no further compliance with Section 106 is required. 2. Archaeological Resources In their letter dated December 30, 1993 (see pages A-1 and A-2 of the Appendix), the State Historic Preservation Office recommended that the North Carolina Department of Transportation conduct a comprehensive archaeological survey of the project area. The project area had never been systematically surveyed. Although there were no recorded archaeological sites within the project boundaries, the State Historic Preservation Office indicated that the floodplain in which Bridge Number 40 is located has a high potential for having archaeological sites. An archaeological survey of the proposed construction area for the temporary detour north of the existing bridge was completed on October 17, 1994 by Deborah Joy and Megan O'Connell, North Carolina Department of Transportation archaeologists. During the intensive survey of the study area, no significant archaeological sites were found. No further archaeological work is recommended. The State Historic Preservation Office concurred with this conclusion in their January, 1995 letter, which is included in the Appendix (see page A-3). C. Natural Environment The proposed project site lies approximately 22.4 km (14 mi) northeast of Lenoir near the community of Grandin in Caldwell County. Caldwell County is a mixture of remote wooded mountains, open piedmont farmland, and urban-industrial areas. The area immediately surrounding the project site is dominated by open piedmont farmland surrounded by low forested hills. Preliminary resource information was gathered and reviewed prior to a visit to the project site. Information sources used include the following: U.S. Geological Survey (USGS) quadrangle mapping (Grandin, N.C.), Soil Conservation Service (SCS) soils mapping of this section of 8 Caldwell County, an aerial photograph of project area (1:1200), North Carolina Division of Environmental Management (DEM) water quality classification for the Yadkin River Basin, Fish and Wildlife Service (FWS) list of protected species, and North Carolina Natural Heritage Program (NC-NHP) database of uncommon and protected species and unique habitats. Field surveys were conducted along the proposed project alignment on September 9, 1994. Plant communities were identified and recorded. Wildlife was identified using a number of observation techniques: active searching, visual observation (binoculars), and recording the identifying signs of wildlife (sounds, scat, tracks, and burrows). Cursory surveys of aquatic communities were conducted examining the stream for visible signs of stream life. 1. Physiography and Soils Caldwell County is in the northwestern part of North Carolina and lies within two physiographic regions. The northern part of the county is in the Blue Ridge Mountain region of the Mountain Physiographic Province. The Kings Creek project site is in this section of the county. The southern part of the county is in the Southern Piedmont Region of the Piedmont Physiographic Province. Elevations in the county range from 1776 m (5920 ft) near Grandfather Mountain in the northeastern part of the county to 828 m (920 ft) in the southeast. Project area elevation ranges from 330 m (1100 ft) to 336 m (1120 ft). The topography at the project site is relatively level consisting of slightly sloping floodplains. The soils found at this project site are primarily Congaree fine sandy loam, occasionally flooded. The Congaree series consists of well-drained to moderately well drained soils that formed in recent alluvium on flood plains. Small areas of Masada loam, 8 to 15 percent slopes, and Pacolet fine sandy loam, 15 to 25 percent slopes, are found along the shoulders of the existing roadway as the elevation rises toward the northeastern end of the project. While neither of these soils is listed as prime farmland, the Congaree fine sandy loam, occasionally flooded, and the Masada loam, 8 to 15 percent slopes, are both listed as state and locally important farmlands. 2. Water Resources This section describes the physical characteristics, Best Usage Standards, and water quality of the water resources to be impacted by the proposed project. Probable impacts to these waters are also discussed. a. Waters Impacted Kings Creek is a tributary to the Yadkin River at river mile 218 in the Yadkin River Basin. This stream flows southwest to northwest at the project site and joins the Yadkin River approximately 1.6 km (1 mi) downstream of the existing bridge. b. Stream Characteristics Kings Creek is approximately 5.7 m (19 ft) wide at the project site and has depths which range from 0.3 m (1 ft) to 1.2 m (4 ft). There are higher water levels at times as evidenced by scoured banks and accumulated sand and debris on the upstream side of the bridge. The substrate is composed of boulders, rubble, and sand, all heavily silted. Turbidity is moderate to high due to run-off from surrounding agricultural fields. C. Best Usage Classification Kings Creek, from its source to the Yadkin River, has been assigned a best usage classification of Class C by the North Carolina Department of Environment, Health, and Natural Resources (DEHNR), 1993. Class C designates waters suitable for aquatic life, propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The stretch of the Yadkin River receiving waters from Kings Creek is also classified Class C Tr. The supplemental classification of Tr is intended to protect fresh waters for natural trout propagation and the survival of stocked trout. No waters classified as High Quality Waters (HQW), Outstanding Resource Waters (ORW), WS-I, or WS-II occur within 1.6 km (1 mi) of the project area. No impacts to sensitive water resources of any kind will take place as a result of project construction. d. Water Quality The Benthic Macro invertebrate Ambient Network (BMAN) assesses water quality by sampling for selected benthic macroinvertebrate organisms. The species richness and overall biomass are reflections of water quality. No sampling has been recorded for Kings Creek. The closest sampling of the Yadkin River was done approximately 11.2 km (7 mi) upstream of the mouth of Kings Creek at Patterson on NC 268 in 1990. The bioclass at that site was Good. The National Pollutant Discharge Elimination System (NPDES) lists one permitted discharge into Kings Creek. Kings Creek School is permitted to discharge treated wastewater into Kings Creek approximately 6.6 km (4.1 mi) upstream of the project site. e. Anticipated Impacts: Water Resources Potential Impacts to water resources in the project area will result from substrate disturbance, sedimentation, and increased turbidity, as well as discharge of toxic substances from construction machinery and road run-off. Wet concrete contacting the river water can also cause degradation of water quality. These impacts may result in a decrease of dissolved oxygen in the stream; an increase of water temperature; a decline in organisms that serve as the basis for aquatic food chains; and the smothering of eggs of spawning game fish. 10 The silt load carried by this stream is already high, and any additional siltation will further degrade Kings Creek. Just upstream of the existing bridge, Kings Creek has a large meander. Debris under the existing bridge probably caused sediment to build and create this meander. A cleanout of the bridge opening just upstream will be necessary to ensure optimum flow conveyance, but it will also increase the risk of further siltation. Except for this cleanout, no channel changes are proposed as a part of the project. It has been recommended that the channel bank on the southwest side of Grandin Road (SR 1552) be riprapped for a length of 50 m (160 ft) to eliminate further erosion and protect the new bridge. Strict application of sedimentation control policies and Best Management Practices will be followed to avoid serious damage to the aquatic environment both at the project site and receiving waters downstream. 3. Biotic Resources This section describes the communities of flora and fauna. These descriptions include the dominant plants and animals in each community and their relationships with each other. Scientific nomenclature and common names, where applicable, are used for the species described. Subsequent references to the same species only use the common name. No animal species were observed directly during the field survey, but representative listings of animal species likely to occur in the area are given. Complete listings of the flora and fauna which may occur in the study area can be found in one or more of the technical references listed on pages A-5 and A-6 of the Appendix. a. Terrestrial Communities The entire area surrounding this project site has been altered by man's activities, which include road construction and agriculture. Only a few plants remain that were part of the original Piedmont/Low Mountain Alluvial Forest that occupied this floodplain before it was cleared for farming. Man Dominated Community This highly disturbed community is dominated by cultivated corn fields and maintained roadsides. Many of the plants found here in addition to corn plants are weedy species adapted to disturbed, maintained areas. The frequently mowed roadside is dominated by fescue grass (Festuca spp.). Other herbaceous species here include red clover (Trifolium pratense), elephants foot (Elephantopus tomentosus), dandelion (Taraxacum officinale) and dayflower (Commelina communis). The less frequently maintained road right-of-way and the drainage ditch between the roadside and the cornfield is dominated by tall weedy herbs, vines, shrub, and tree sprouts. Herbaceous species 11 include Johnson grass (Sorghum halepense), yarrow (Achillea millefolium), jewel-weed (Impatiens capensiiss), wingstem (Verbesina occi enta is), wild lettuce Lactuca f of ridana), pokeweed P?to a?cca americana), knotweed (Pol onum ennsy-Fv'an cum), ragweeds (Ambrosia trif- -da, A. artemisiifolia , golden rods (Solidago spp.), teartthiumb (Polygonum sa ittatum), purple-stem aster (Aster punic?eus), ironweed (Vernonia noveboracensis), and Joe-Pye-weed Eupatoriumistulosum). Vines present inc u e Japanese honeysuckle (Lonicera Japonica), poison ivy (Toxicodendron radicans), Virgins bower (Clematis virginiana), climbing buckwheat (Polygonum convolvulus), grape (Vitis sp.), cane (Arundinaria giganteeaa), burdock Arctium minus), greenbrier (Smilax spp.), bouncing Bet (Saponaria fficinaTis), and trumpet vine (Campsis radicans). Shrubs include blac erry (Rubus sp.), privet (Ligustrum sinense), staghorn sumac (Rhus typhin_a), smooth sumac (Rhus labra), ann elderberry (Sambucus canadensis). Tree species occurring as sprouts in cut-over areas an a few mature individuals along the edge of the creek include: box elder (Acer ne undo), river birch (Betula nigra), sycamore (Platanus occi entalis), black walnut (Juglans nigra), poplar Lirio endron tulipifera), and black cherry (Prunus serotina). Resident animal species would be few in these disturbed areas. However, many opportunistic species which may reside in nearby communities would utilize these areas for feeding zones. Seeds, berries, fruits, and insects, as well as living and dead animal matter, attract a wide variety of foraging animals including: eastern cottontail (S,ylvilagus floridanus), opossum (Didelphis vir iniana), wood chuck (Marmota monax), white-tailed deer (Odocoi eus virginianus), white-footed mouse (Perom scus leucopus), isp cotton rat (Sigmodon hispidus), and raccoon Procyon lotor). Birds likely to visit the area are American crow (Corvus brachyrhychos), barn swallows (Hirundo rustica), carolina chickadees (Parus carolinensis), mourning dove (Zenaida macroura), carolina wren (Thr- yo?ti-orus ludovicianus), common grackle (uiscalus quiscula), and cardinal (Cardinalis cardinalis). Roadkills may attract scavenging animals such as turkey vultures (Catharter aura), common crows, and opossums. Reptiles and amphi fans, including toads, box turtles, snakes, and lizards, may sun themselves on the roadsides or crawl onto the warm road surface at night. These may include American Toad (Bufo americanus), eastern box turtle (Terrapene carolina), black racer snake (Coluber constrictor), eastern hognose snake (Heterodon platyrhinos), and five- iineTskink (Eumeces fasciatus). b. Aquatic Communities Aquatic invertebrates are a major component of stream ecosystems as primary and secondary consumers and as prey species for organisms higher in the food chain. Aquatic invertebrates, including crayfish Cambaridae sp.), and some insects are present in Kings Creek. However, their numbers are limited by the heavy siltation that would tend to clog gills and smother bottom-dwelling invertebrates in this stream. 12 Amphibian and reptile species likely to occur in and around this stream include snapping turtle (Chel d?ra ser entina), northern water snake (Nerodia sipedon), and green frogs Rana c amitans). According to Joe Mickey, N.C. Fisheries Biologist, the most likely fish species to occur in Kings Creek include: bluehead chub (Nocomis leptocephalus), fantail darter (Etheostoma flabellare), rosyside dace (Clinostomus funduloides), and-it whe sucker (Catostomus commersoni). Other fish that have been reported from this area of the Yadkin River drainage include: highback chub (Hybopsis hypsinotus), redlip shiner (Notropis chiliticus), fiery black shiner (Notropis ,yrrhomelas), northern hog sucker (Hypenntelium ni ricans), striped jumprock Moxostoma rupiscartes), and margined ma tom (Noturus insignis). C. Anticipated Impacts: Biotic Communities Biotic community impacts resulting from the project construction are being addressed separately as terrestrial impacts and aquatic impacts. However, it is important to remember that construction impacts may not be restricted to the community in which the construction activity occurs. All measures possible should be taken to ensure no sediment leaves the construction site. Terrestrial Impacts Most of the project area has been highly disturbed by previous roadway construction and agricultural fields. New fill would be required for either Alternative 1 (temporary detour construction) or Alternative 2 (permanent realignment of roadway), thereby increasing the risk of soil erosion. Alternative 3 would replace the bridge in its present location with road closure and would result in the least new disturbance. The proposed right-of-way width of all alternates would be 18.3 m (60 feet). Construction will result in the loss and displacement of some plant and animal life, regardless of the alternative chosen. However, previous disturbance at this site has already limited plant and animal species, so the impact will also be limited. The anticipated area to be impacted within this community is presented for each alternative in Table 1. Table 1. Anticipated Impacts to the Biotic Community (Man-Dominated Community) Alternative 1 Alternative 2 Alternative 3 tare/acre 0.7/1.8 0.9/2.3 0.3/0.7 * Alternative 1 impacts include those of the proposed temporary detour. 13 Aquatic Community Project construction is likely to temporarily increase sediment loads in this already heavily silted creek. Construction-related sedimentation can be harmful to local populations of invertebrates which are important to aquatic, and some terrestrial, food chains. Less mobile species, such as filter feeders, may be covered and smothered by substrate disturbance and sedimentation resulting from construction related erosion. Increased sediment loads and suspended particulates may smother fish eggs, reduce oxygen-carrying capacity, and raise water temperatures. Contact with wet cement will also affect water quality and aquatic organisms. If spawning habits or habitats are altered, it could affect game fish populations in the Yadkin River. The close proximity of the Yadkin River, which is located approximately 1.6 km (1 mile) downstream, increases the possibility that erosion at this construction site could also increase sediment loads in the river. Bridge construction will be accomplished so that wet concrete does not come in contact with creek water to reduce the possibility of a fish kill. Other concerns at this site would be the possibility of increased concentrations of toxic compounds (gasoline, oil, etc.) reaching the stream from construction machinery or run-off from the new bridge. Best Management Practices (BMPs) for protection of surface waters will be strictly followed to protect the biological integrity and water quality at this site. 4. Jurisdictional Issues a. Waters of the United States Wetlands and surface waters fall under the broad category of Waters of the United States as defined in 33 CFR 328.3 and in accordance with provisions of section 404 of the Clean Water Act (33 U.S.C. 1344) and are regulated by the U.S. Army Corps of Engineers (C.O.E.). Potential wetland communities were evaluated using the criteria specified in the 1987 U.S. Army Corps of Engineers Wetlands Delineation Manual. For an area to be designated wetlands, the following three specifications must be met: 1) presence of hydric soils, 2) presence of hydrophytic vegetation, and 3) evidence of hydrology, or hydrological indicators, including: saturated soils, stained oxidized rhizospheres, matted vegetation, high water marks on trees, buttressed tree bases, and surface roots. No wetland communities are located within the proposed right of way limits of the studied alternatives. Construction of the proposed project will have no impacts on any jurisdictional wetlands. 14 Permits Construction is likely to be authorized by provisions of General Nationwide permit 33 CFR 330.5 (a) (23). Caldwell County is one of 25 counties designated as having trout waters. Projects in these counties must be reviewed and approved by the North Carolina Wildlife Resources Commission prior to the issuance of the COE permit. Also, Section 401 of the Clean Water Act (CWA) requires that the state issue or deny water quality certification for any federally permitted or licensed activity that may result in a discharge to the waters of the United States prior to issuance of COE permits. In her November, 1993 letter, included in the Appendix (see page A-4), the North Carolina Wildlife Resources Commission's Mountain Region Coordinator, Stephanie E. Goudreau, stated that trout do not occur at this project site, and there are no other known special concerns. Mitigation Since this project will likely be authorized under a Nationwide permit, mitigation for impacts to surface waters is generally not required by the Corps of Engineers. A final determination regarding mitigation requirements, however, rests with Corps of Engineers. b. Rare or Protected Species Federal law requires that any action, which has the potential to have a detrimental impact to the survival and well-being of any species classified as federally protected, is subject to review by the FWS and/or the National Marine Fisheries Service under the provisions of the Endangered Species Act (ESA) of 1973, as amended. Endangered species receive additional protection under separate state statutes. In North Carolina, protection of plant species falls under N.C. General Statutes (G.S.) 106-202.12 to 106-202.19 of 1979. Wildlife protection falls under G.S. 113-331 to 113-337 of 1987. 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 of 1973, as amended. The Fish and Wildlife Service (FWS) lists four (4) federally protected species for Caldwell County as of April 6, 1995. These species are listed in Table 2. 15 Table 2. Federally Protected Species - Caldwell County SCIENTIFIC NAME COMMON NAME STATUS * Mirohexura montivaga Spruce-fir moss spider E Geum ra iatum Spreading avens E Liatris e eri Hellers blazing star T So-hi?f`ago sppithamaea Blue Ridge goldenrod T * E denotes Endangered a species that is threatened with extinction throughout all or a significant portion of its range.) T denotes Threatened (a species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.) Mirohexura montivaga (Spruce-fir moss spider) E Animal Family: Dipluridae Federally Listed: March, 1994 Distribution in N.C.: Avery, Caldwell, Swain The spruce-fir moss spider is a very small spider. Adults measure only 3.0 to 5.6 mm (1/4 - 7/16 in). Coloration ranges from light brown to a darker reddish brown, and there are no markings on the abdomen. The carapace is generally yellowish brown. The most reliable field identification characteristics for the spruce-fir moss spider are a pair of very long posterior spinnerets and the presence of a second pair of book lungs, which appear as light patches posterior to the genital furrow. The typical habitat of this spider is found in well-drained moss (and liverwort) mats growing on rocks or boulders in well-shaded situations in mature, high-elevation Fraser fir and red spruce forests. No critical habitat has been designated. BIOLOGICAL CONCLUSION: NO EFFECT The study area does not contain suitable habitat for the spruce-fir moss spider. No impact to this species will occur from proposed construction. Geum radiatum (Spreading avens) E Plant Family: Rosaceae Date Listed: April 5, 1990 Flowers Present: June-early July Distribution in N.C.: Ashe, Avery, Mitchell, Stokes, Transylvania, Buncombe, Burke, Caldwell, Watauga, Yancey. Spreading avens is a perennial herb having stems with an indefinite cyme of bright yellow radially symmetrical flowers. Flowers of spreading avens are present from June to early July. 16 Spreading avens has basal leaves which are odd-pinnately compound; terminal leaflets are kidney shaped and much larger than the lateral leaflets, which are reduced or absent. Spreading avens is found only in the North Carolina and Tennessee sections of the Southern Appalachian Mountains. Spreading avens occurs on scarps, bluffs, cliffs, and escarpments on mountains, hills, and ridges. Known populations of this plant have been found to occur at elevations of 1535-1541 meters (5060-5080 feet), 1723-1747 meters (5680-5760 feet), and 1759 meters (5800 feet). Other habitat requirements for this species include full sunlight and shallow acidic soils. These soils contain a composition of sand, pebbles, humus, sandy loam, clay loam, and humus. Most populations are pioneers on rocky outcrops. BIOLOGICAL CONCLUSION: NO EFFECT No habitat exists in the project study area for the spreading avens. It can be concluded that the subject project will not impact this Endangered species. Liatris helleri -(Remblazing star) T Plant Family: Asteraceae Federally Listed: November 19, 1987 Flowers Present: Late June - August Distribution in N.C.: Ashe, Avery, Burke, Caldwell, Mitchell, Watauga This plant is endemic to high elevation ledges of rock outcrops of the northern Blue Ridge Mountains in North Carolina. Of nine historic populations, only seven remain in existence. Hellers blazing star is a short, stocky plant that has one or more erect stems that arise from a tuft of narrow, pale green basal leaves. Leaves are acuminate and diminish in size and breadth upward on the stem. Stems are 0.4 m (16 inches) tall and are topped with a raceme of small 0.1-0.2 m (4-8 inches) lavender flowers. Fruits are present from September to November. This plant is a high altitude early pioneer species and can be found growing on high elevation ledges of rock outcrops in grassy areas where it is exposed to full sunlight. It prefers shallow acid soils associated with granite rocks. BIOLOGICAL CONCLUSION: NO EFFECT The study area does not support suitable habitat for Hellers blazing star. No impacts to Hellers blazing star will occur from proposed construction. 17 Solida o spithamaea Blue Ridge Goldenrod) T Plant Family: Asteraceae Federally Listed: April 29, 1985 Flowers Present: July to September Distribution in N.C.: Avery, Caldwell, Mitchell Blue Ridge goldenrod is an erect perennial herb 1-4 dm (4-16 inches) tall that arises from a short stout rhizome. The yellow flowers are borne in heads arranged in a corymbiform inflorescence. Calyx is represented by a pappus of numerous, capillary, upwardly barbellate white bristles, 2.5-3.5 mm long. Solidago spithamaea grows above 1400 m (4,600 ft) in dry rock crevices of granite outcrops on the high peaks of the Blue Ridge Mountains. No critical habitat has been designated for Blue Ridge goldenrod. BIOLOGICAL CONCLUSION: NO EFFECT The study area does not contain suitable habitat for this species. No impact to Blue Ridge goldenrod will occur from proposed construction. C. Federal Candidate and State Protected Species There are eight (8) Federal Candidate 2 (C2) species listed for Caldwell County. Candidate 2 (C2) species are defined as taxa for which there is some evidence of vulnerability, but for which there are not enough data to warrant a listing of Endangered, Threatened, Proposed Endangered, or Proposed Threatened at this time. These species are mentioned here for informational purposes, should they become protected in the future. Table 3 lists these federal candidate species. The North Carolina status of these species is also listed in Table 3. Plants or animals with state designations of Endangered (E), Threatened (T), or Special Concern (SC) are given protection by the State Endangered Species Act and the N.C. Plant Protection and Conservation Act of 1979, administered and enforced by the North Carolina Wildlife Resources Commission and the North Carolina Department of Agriculture. 18 Table 3.

Threatened species are those likely to become an endangered species in the state if not protected. SC = Special Concern. A species of plant in North Carolina that requires monitoring. These may be collected from the wild and sold under specific regulations. C = Candidate. Species which are rare in North Carolina for various reasons and are likely to merit listing as Endangered or Threatened if they continue to decline. SR = Significantly Rare. Species very rare in N.C. whose numbers are significantly reduced by habitat destruction, disease, or direct exploitation. Usually more common somewhere else in their range. Surveys for these species were not conducted during site visits, nor were any of these species observed. D. Air Quality and Traffic Noise The bridge replacement project is located within the jurisdiction for air quality of the Winston-Salem Regional Office of the North Carolina Department of Environment, Health, and Natural Resources. The proposed project is located in Caldwell County, which has been determined to be in compliance with the National Ambient Air Quality Standards. 40 CFR part 51 is not applicable, because the 19 proposed project is located in an attainment area. This project is not anticipated to create any adverse effects on the air quality of this attainment area. The project involves the removal and replacement of Bridge Number 40 on SR 1552 over Kings Creek. No additional through lanes are planned, and the project will not substantially increase traffic volumes. Due to the aforementioned factors and low anticipated future traffic, the project's impact on noise and air quality will be insignificant. Noise levels could increase in the area during construction, but this increase 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 for highway traffic noise (23 CFR Part 772) and for air quality (1990 CAAA and NEPA), and no additional reports are required. E. Flood Hazard Evaluation Caldwell County is a participant in the National Flood Insurance Regular Program. Kings Creek is not included in a detailed flood study. A copy of the Flood Insurance Rate Map with the approximate limits of the 100-year floodplain is included as Figure 4. The floodplain in the vicinity of the project is rural and wooded with mostly agricultural uses. There are no buildings in the project vicinity with floor elevations below the 100-year floodplain. The proposed bridge replacement will not adversely affect the floodplain. F. Relocations No businesses or residences will be relocated as part of the proposed project. G. Hazardous Materials No hazardous waste sites were identified in the project vicinity. H. Section 4(f) Properties The proposed project will not impact any properties eligible for protection under Section 4(f) of the Department of Transportation Act of 1966. X. CONCLUSION Bridge Number 40 on SR 1552 (Grandin Road) over Kings Creek in Caldwell County will be replaced at its existing location with a 55 m (180-foot) bridge. A temporary on-site detour including a 23 m (75-foot) detour bridge located 10 m (30 feet) north of the existing bridge is also recommended. 20 No substantial environmental impacts are anticipated as a part of this project, therefore, the proposed project is considered to be a "categorical exclusion" as defined by the Federal Highway Administration's environmental guidelines (23 CFR 771.117).

CE/ SAN 0 4 , Fes-m,01SIC v OF S, n Dr Arc?ives?and4 On November 16, 1993, Robin Stancil of our staff met with North Carolina Department of Transportation (NCDOT) staff for a meeting of the minds concerning the above project. 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 and for our use afterwards. 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 the following historic structures in the general project area: Grandin Baptist Church. On SR 1573 just west of the junction with SR 1562. There are no known recorded archaeological sites within the project boundaries. However, the project area has never been systematically surveyed to determine the location of significance of archaeological resources. The floodplain in which Bridge 40 is located is considered to be of high probability for the location of archaeological sites. It We recommend that a comprehensive survey be conducted by a NCDOT archaeologist to identify the presence and significance of archaeological remains that may be damaged or destroyed by the proposed bridge. Potential effects on unknown resources should be assessed prior to the initiation of construction activities. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which indicates how NCDOT addressed our comments.

Kings Creek is somewhat degraded and does not support trout in the project area; therefore, trout are not an issue to the NCWRC. However, we anticipate commenting on this project through the 404 permit process because Caldwell County is considered a trout county by the U.S. Army Corps of Engineers. Our comments will reflect that this stream does not support trout. Thank you for the opportunity to provide input to the early planning stages for this project.

A-5 Caldwell County Bridge No. 40 on SR 1552 Over Kings Creek Federal Aid Project BRZ-1552(4) State Project 8.2731901 TIP Project B-2525 Bridge Number 40 has been included in the Federal Aid Bridge Replacement Program. The location of Bridge Number 40 on SR 1552 over Kings Creek is shown in Figure 1. No substantial environmental impacts are anticipated as a part of this project, therefore, the proposed project is considered to be a "categorical exclusion" as defined by the Federal Highway Administration's environmental guidelines (23 CFR 771.117). I. SUMMARY OF ENVIRONMENTAL COMMITMENTS In order to minimize impacts to water resources at the project site and receiving waters downstream, NCDOT's Best Management Practices for the Protection of Surface Waters and Sediment Control Guidelines will be strictly enforced during the construction of the proposed project. Construction is likely to be authorized by provisions of the United States Army Corps of Engineers' General Nationwide Permit 33 CFR 330.5 (a)(23). Since Kings Creek is designated as a trout stream, this project must be reviewed and approved by the North Carolina Wildlife Resources Commission prior to the issuance of the Nationwide Permit. Also, the proposed project will require a Section 401 Water Quality General Certification from the Division of Environmental Management (DEM) prior to the approval of Section 404 authorization. II. PROJECT STATUS The proposed project is included in the North Carolina Department of Transportation's 1995-2001 Transportation Improvement Program (TIP). The 1995-2001 TIP includes $ 20,000 for right of way acquisition in fiscal year 1995 and $ 625,000 for construction in fiscal year 1996 for a total funding of $ 645,000. The proposed project is funded with bridge replacement funds for bridges that are not on the Federal Aid System. Cost estimates for the proposed project were updated during the planning process. Currently, the total cost of the project is anticipated to be $810,000. This estimate includes $775,000 for construction and $35,000 for right of way acquisition. III. SUMMARY OF RECOMMENDATIONS Bridge Number 40 on SR 1552 (Grandin Road) over Kings Creek in Caldwell County will be replaced at its existing location with a bridge 55 m (180 feet) in length (see Alternative 1 in Figure 2). A temporary detour bridge 23 m (75 feet) in length located 10 m (30 feet) north of the existing bridge is also recommended. Both the permanent bridge and the 2 temporary detour structure will have clear roadway widths of 7.9 m (26 feet) in order to provide for two 3.4 m (11-foot) lanes and 0.6 m (2-foot) shoulders. Temporary construction easements will be needed on the north side of the bridge to contain the proposed temporary on-site detour, which will be approximately 137 m (450 feet) in length. Please note that the bridge lengths specified in this report may be increased or decreased once more detailed hydrologic analyses are done during final design. Replacing Bridge Number 40 in its existing location will maintain the 0.4 km (0.25 mile) tangent section on SR 1552 in the vicinity of the bridge, and the proposed temporary on-site detour will enable the bridge to be replaced with little or no inconvenience to the motoring public. A 60 mph design speed will be used to design the bridge. A cleanout of the bridge opening just upstream (south) of the existing bridge is recommended to ensure optimum flow conveyance under the proposed bridge. Placing riprap on the west channel bank south of the bridge for a length of 50 m (160 feet) is also recommended to eliminate further erosion of the bank and to protect the end bent of the bridge from scour. The roadway approaches to the bridge will also be improved to tie the existing roadway to the proposed bridge. The roadway will be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge. IV. EXISTING CONDITIONS A. Roadway SR 1552 in Caldwell County is classified as a rural local route in the Statewide Functional Classification System and is not part of the Federal Aid System. Near Bridge Number 40 over Kings Creek, SR 1552 has a 4.9 m (16-foot) wide travelway with 1.2 m (4-foot) grassed shoulders. In the vicinity of the bridge, both the vertical and horizontal alignments of SR 1552 are good. Bridge Number 40 lies on a 0.4 km (0.25 mile) tangent section of SR 1552. Photographs of the approaches to the existing bridge are shown in Figure 3. The statutory 55 mph speed limit is enforced along SR 1552. B. Traffic Volumes In the construction year 1996, the average daily traffic on SR 1552 is anticipated to be 400 vehicles per day. In 2016, the traffic volume on SR 1552 is expected to increase to 700 vpd. The projected traffic volume includes 1% truck-tractor semi-trailers and 2% dual-tired vehicles. Three school buses cross Bridge Number 40 on SR 1552 twice daily. C. Existino Structure The existing bridge was constructed in 1966. The superstructure consists of timber flooring on 1-beams and timber joists. The substructure consists of concrete encased timber posts and piles. The overall length of the existing bridge is 42.4 m (139 feet) and the clear roadway width is 5.8 m (19 feet). The structure is situated 5.5 m (18 feet) over the bed of Kings Creek. Presently, the posted weight limit is 10 tons for single vehicles and 18 tons for trucks with trailers. The sufficiency rating for Bridge Number 40 is 16.0, compared to a rating of 100 for a new structure. The estimated remaining life of Bridge Number 40 is two years. Figure 3 includes a photograph of the existing structure. D. Accidents No accidents were reported in the vicinity of Bridge Number 40 during the time period from August 1, 1990 through July 31, 1993. E. Utilities The proposed project will have a low impact on utilities. An underground telephone cable owned by Southern Bell lies along the north side of SR 1552. This cable will require relocating. V. ALTERNATIVES STUDIED Three alternatives for replacing Bridge Number 40 on SR 1552 were studied. All of the design alternatives utilize a 60 mph design speed. Each alternative is shown in Figure 2 and described below. Alternative 1 (recommended) will replace the bridge at its existing location with a bridge 55 m (180 feet) in length. A temporary detour structure 23 m (75 feet) in length will be provided 10 m (30 feet) north of the existing bridge. Both the permanent structure and the temporary detour structure will have clear roadway widths of 7.9 m (26 feet). A temporary on-site detour approximately 137 m (450 feet) in length will be constructed on the north side of SR 1552. This temporary detour will have a 25 mph design speed. This alternative will retain the existing 0.4 km (0.25 mile) tangent section on SR 1552 in the vicinity of the bridge. The roadway approaches to the bridge will also be improved as a part of this alternative. The roadway will be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge making the project length 146 m (480 feet). Alternative 2 would replace Bridge Number 40 on new location. A bridge 55 m 180 feet) in length would be constructed approximately 10 m (30 feet) north of the existing bridge. This structure would have a clear roadway width of 7.9 m (26 feet). SR 1552 would be realigned on the north side of the existing roadway from the existing curve east of the bridge to approximately 305 m (1000 feet) west of the bridge, a length of 0.49 km (0.30 mile). This alternative would introduce two additional curves into the alignment of SR 1552 in the vicinity of the subject bridge. This alternative would allow motorists to continue using the existing bridge while the new bridge and roadway are constructed. 4 Alternative 3 would replace the bridge at its existing location with a brim ge 55 m (180 feet) in length with a 7.9 m (26-foot) clear roadway width. The road would be closed for approximately 9 months during construction, and traffic would be detoured onto other (unpaved) secondary roads in the area (see Figure 1). Detouring traffic off-site is discussed further in Section VII. The roadway approaches to the bridge would also be improved as part of this alternative. The roadway would be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge, making the total project length 146 m (480 feet). Both rehabilitation of the existing bridge and the "do nothing" alternative were considered early in the project study, but were eliminated from consideration. Due to the existing bridge's poor condition, rehabilitating the existing structure is not feasible. The "do nothing" alternative would eventually necessitate closure of the bridge and would thereby eliminate the traffic service provided by SR 1552. VI. COST ESTIMATES Construction and right of way cost estimates for the studied alternatives are presented below. Contract Cost Engineering and Contingencies Total Construction Cost Right of Way and Utilities Total Cost of Alternative Alt. 1 Alt. 2 Alt. 3 $ 675,000 $ 660,000 $ 358,000 $ 100,000 $ 100,000 $ 67,000 $ 775,000 $ 760,000 $ 425,000 $ 35,000 $ 50,000 $ 31,500 $ 810,000 $ 810,000 $ 456,500 * Note: The costs shown for Alternative 3 do not include the costs of upgrading unpaved secondary roads in the project area. This upgrading would be required in order to provide an adequate off-site detour (see Section VII). In addition, these costs do not include the additional road user costs that would result from increased travel distances. VII. OFF-SITE TRAFFIC DETOUR Traffic will be maintained on-site during the replacement of Bridge Number 40 on SR 1552. SR 1552 serves as a connector between NC 18 and NC 268 in northeastern Caldwell County (see Figure 1). No other paved roads which connect NC 18 and NC 268 are located in the northeastern 1 5 portion of the county. Road closure during replacement of the subject bridge would greatly inconvenience school bus traffic, as well as local farmers, who regularly cross Bridge Number 40. If the road were closed during the replacement of Bridge Number 40, approximately 1 mile of additional travel would be required for through traffic. All traffic which currently crosses Bridge Number 40 would have to travel on SR 1511 (Howell Farm Road) and SR 1551 if SR 1552 were closed during bridge construction. SR 1511, is an unpaved, narrow roadway with limited sight distance. The roadway has a high number of curves and has several steep cut and fill slopes immediately adjacent to the roadway. Traffic moving from SR 1510 (Tom Dula Road) to SR 1573 (Howell Farm Road) would be required to travel an additional 13.8 km (8.6 miles) as a result of road closure at the bridge. Improvements to SR 1511 (realignment and paving) would be required before that route could be used as a temporary detour. SR 1511 is not anticipated to be paved before the bridge is replaced. Improvements to SR 1511 would be expensive and more damaging to the environment than the temporary detour and structure proposed under Alternative 1, since SR 1511 parallels Little Kings Creek for most of its length. In conclusion, SR 1511 is not suited to accommodate detour traffic from SR 1552, and improvements to SR 1511 would be more environmentally damaging and expensive than the recommended on-site detour. It is anticipated that the cost of realigning and paving SR 1511 would exceed the cost of constructing the recommended on-site temporary detour. Therefore, the recommended on-site temporary detour is preferred to detouring traffic off-site. VIII. RECOMMENDED IMPROVEMENTS Alternative 1 (see Figure 2) is recommended for replacing Bridge Number 40 on SR 1552 over Kings Creek. This alternative calls for replacing the bridge at its existing location with a bridge 55 m (180 feet) in length. A temporary detour bridge 23 m (75 feet) in length located 10 m (30 feet) north of the existing bridge is also recommended. Both the permanent structure and the temporary detour structure will have clear roadway widths of 7.9 m (26 feet). Temporary construction easements will be needed on the north side of SR 1552 to contain the proposed temporary on-site detour. A 60 mph design speed will be used to design the permanent bridge and approaches. A 25 mph design speed will be used for the temporary detour. Replacing Bridge Number 40 in its existing location will maintain the 0.4 km (0.25 mile) tangent section on SR 1552 in the vicinity of the bridge. The roadway approaches to the bridge will also be improved. The roadway will be improved for a distance of 46 m (150 feet) on both sides of the proposed bridge. Also as a part of the proposed project, a cleanout of the bridge opening just upstream (south) of the existing bridge is proposed to ensure optimum flow conveyance. Debris under the existing bridge caused a 6 sediment buildup just upstream of the existing bridge and created a meander in Kings Creek. The sediment buildup has limited the existing bridge's flow conveyance. In order to eliminate further erosion, the west stream bank on the south side of the proposed bridge will be riprapped for a length of 50 m (160 feet). An on-site temporary detour will be provided. This detour will enable the existing bridge to be removed and replaced with little or no inconvenience to the motoring public. As described in Section VII., if SR 1552 were closed during bridge construction, motorists would have to use SR 1511, an unimproved road, to travel through the area. The cost of improving SR 1511 in order to make it suitable for traffic from SR 1552 would be more expensive than the recommended temporary on-site detour. Alternative 1 is considered to be the best alternative. Alternative 1 maintains the existing horizontal alignment and maintains traffic on-site. Alternative 1 causes the least inconvenience to the motoring public and has fewer environmental impacts than Alternative 2. IX. ENVIRONMENTAL IMPACTS A. Prime and Important Farmland The Farmland Protection Policy Act of 1981 (FPPA) requires all federal agencies to consider the impact of land acquisition and construction projects on prime and important farmland soils. These soils are designated by the United States Soil Conservation Service (SCS). In compliance with the Act, the SCS was asked to review the proposed bridge replacement project and determine whether any farmland soils will be impacted. The SCS did not respond within the 45 day review period established by FPPA regulations; therefore, the Farmland Protection Policy Act of 1981 (FPPA) does not apply to this project. B. Historic and Cultural Resources 1. Historic Architectural Resources 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 general project area was reviewed in the field by North Carolina Department of Transportation staff. The North Carolina Department of Transportation and the State Historic Preservation Office (SHPO) met on November 16, 1993 to discuss the project. The North Carolina Department of Transportation provided project area photographs and aerial photographs and reviewed them with SHPO. Grandin Baptist Church is the only property over fifty years old within the general project area. This property is located on SR 1573 (Howell Farm Road) south of SR 1552 (see Figure 2). 7 In a letter dated December 30, 1993, SHPO offered their preliminary comments. In terms of historic architectural resources, they were aware of the presence of Grandin Baptist Church in the general project area. A copy of this SHPO letter is included in the Appendix (see pages A-1 and A-2). On March 1, 1994, North Carolina Department of Transportation staff showed SHPO staff the tax parcel map for Grandin Baptist Church. The church property is not contiguous with SR 1552 (Grandin Road) or with Bridge Number 40 and therefore is not within the project's area of potential effect. North Carolina Department of Transportation and SHPO are in agreement that there are no properties within the project's area of potential effect that are either listed in or eligible for the National Register; therefore, no further compliance with Section 106 is required. 2. Archaeological Resources In their letter dated December 30, 1993 (see pages A-1 and A-2 of the Appendix), the State Historic Preservation Office recommended that the North Carolina Department of Transportation conduct a comprehensive archaeological survey of the project area. The project area had never been systematically surveyed. Although there were no recorded archaeological sites within the project boundaries, the State Historic Preservation Office indicated that the floodplain in which Bridge Number 40 is located has a high potential for having archaeological sites. An archaeological survey of the proposed construction area for the temporary detour north of the existing bridge was completed on October 17, 1994 by Deborah Joy and Megan O'Connell, North Carolina Department of Transportation archaeologists. During the intensive survey of the study area, no significant archaeological sites were found. No further archaeological work is recommended. The State Historic Preservation Office concurred with this conclusion in their January, 1995 letter, which is included in the Appendix (see page A-3). C. Natural Environment The proposed project site lies approximately 22.4 km (14 mi) northeast of Lenoir near the community of Grandin in Caldwell County. Caldwell County is a mixture of remote wooded mountains, open piedmont farmland, and urban-industrial areas. The area immediately surrounding the project site is dominated by open piedmont farmland surrounded by low forested hills. Preliminary resource information was gathered and reviewed prior to a visit to the project site. Information sources used include the following: U.S. Geological Survey (USGS) quadrangle mapping (Grandin, N.C.), Soil Conservation Service (SCS) soils mapping of this section of 8 Caldwell County, an aerial photograph of project area (1:1200), North Carolina Division of Environmental Management (DEM) water quality classification for the Yadkin River Basin, Fish and Wildlife Service (FWS) list of protected species, and North Carolina Natural Heritage Program (NC-NHP) database of uncommon and protected species and unique habitats. Field surveys were conducted along the proposed project alignment on September 9, 1994. Plant communities were identified and recorded. Wildlife was identified using a number of observation techniques: active searching, visual observation (binoculars), and recording the identifying signs of wildlife (sounds, scat, tracks, and burrows). Cursory surveys of aquatic communities were conducted examining the stream for visible signs of stream life. 1. Physiography and Soils Caldwell County is in the northwestern part of North Carolina and lies within two physiographic regions. The northern part of the county is in the Blue Ridge Mountain region of the Mountain Physiographic Province. The Kings Creek project site is in this section of the county. The southern part of the county is in the Southern Piedmont Region of the Piedmont Physiographic Province. Elevations in the county range from 1776 m (5920 ft) near Grandfather Mountain in the northeastern part of the county to 828 m (920 ft) in the southeast. Project area elevation ranges from 330 m (1100 ft) to 336 m (1120 ft). The topography at the project site is relatively level consisting of slightly sloping floodplains. The soils found at this project site are primarily Congaree fine sandy loam, occasionally flooded. The Congaree series consists of well-drained to moderately well drained soils that formed in recent alluvium on flood plains. Small areas of Masada loam, 8 to 15 percent slopes, and Pacolet fine sandy loam, 15 to 25 percent slopes, are found along the shoulders of the existing roadway as the elevation rises toward the northeastern end of the project. While neither of these soils is listed as prime farmland, the Congaree fine sandy loam, occasionally flooded, and the Masada loam, 8 to 15 percent slopes, are both listed as state and locally important farmlands. 2. Water Resources This section describes the physical characteristics, Best Usage Standards, and water quality of the water resources to be impacted by the proposed project. Probable impacts to these waters are also discussed. a. Waters Impacted Kings Creek is a tributary to the Yadkin River at river mile 218 in the Yadkin River Basin. This stream flows southwest to northwest at the project site and joins the Yadkin River approximately 1.6 km (1 mi) downstream of the existing bridge. 9 b. Stream Characteristics Kings Creek is approximately 5.7 m (19 ft) wide at the project site and has depths which range from 0.3 m (1 ft) to 1.2 m (4 ft). There are higher water levels at times as evidenced by scoured banks and accumulated sand and debris on the upstream side of the bridge. The substrate is composed of boulders, rubble, and sand, all heavily silted. Turbidity is moderate to high due to run-off from surrounding agricultural fields. C. Best Usage Classification Kings Creek, from its source to the Yadkin River, has been assigned a best usage classification of Class C by the North Carolina Department of Environment, Health, and Natural Resources (DEHNR), 1993. Class C designates waters suitable for aquatic life, propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The stretch of the Yadkin River receiving waters from Kings Creek is also classified Class C Tr. The supplemental classification of Tr is intended to protect fresh waters for natural trout propagation and the survival of stocked trout. No waters classified as High Quality Waters (HQW), Outstanding Resource Waters (ORW), WS-I, or WS-II occur within 1.6 km (1 mi) of the project area. No impacts to sensitive water resources of any kind will take place as a result of project construction. d. Water Quality The Benthic Macroinvertebrate Ambient Network (BMAN) assesses water quality by sampling for selected benthic macroinvertebrate organisms. The species richness and overall biomass are reflections of water quality. No sampling has been recorded for Kings Creek. The closest sampling of the Yadkin River was done approximately 11.2 km (7 mi) upstream of the mouth of Kings Creek at Patterson on NC 268 in 1990. The bioclass at that site was Good. The National Pollutant Discharge Elimination System (NPDES) lists one permitted discharge into Kings Creek. Kings Creek School is permitted to discharge treated wastewater into Kings Creek approximately 6.6 km (4.1 mi) upstream of the project site. e. Anticipated Impacts: Water Resources Potential Impacts to water resources in the project area will result from substrate disturbance, sedimentation, and increased turbidity, as well as discharge of toxic substances from construction machinery and road run-off. Wet concrete contacting the river water can also cause degradation of water quality. These impacts may result in a decrease of dissolved oxygen in the stream; an increase of water temperature; a decline in organisms that serve as the basis for aquatic food chains; and the smothering of eggs of spawning game fish. 10 The silt load carried by this stream is already high, and any additional siltation will further degrade Kings Creek. Just upstream of the existing bridge, Kings Creek has a large meander. Debris under the existing bridge probably caused sediment to build and create this meander. A cleanout of the bridge opening just upstream will be necessary to ensure optimum flow conveyance, but it will also increase the risk of further siltation. Except for this cleanout, no channel changes are proposed as a part of the project. It has been recommended that the channel bank on the southwest side of Grandin Road (SR 1552) be riprapped for a length of 50 m (160 ft) to eliminate further erosion and protect the new bridge. Strict application of sedimentation control policies and Best Management Practices will be followed to avoid serious damage to the aquatic environment both at the project site and receiving waters downstream. 3. Biotic Resources This section describes the communities of flora and fauna. These descriptions include the dominant plants and animals in each community and their relationships with each other. Scientific nomenclature and common names, where applicable, are used for the species described. Subsequent references to the same species only use the common name. No animal species were observed directly during the field survey, but representative listings of animal species likely to occur in the area are given. Complete listings of the flora and fauna which may occur in the study area can be found in one or more of the technical references listed on pages A-5 and A-6 of the Appendix. a. Terrestrial Communities The entire area surrounding this project site has been altered by man's activities, which include road construction and agriculture. Only a few plants remain that were part of the original Piedmont/Low Mountain Alluvial Forest that occupied this floodplain before it was cleared for farming. Man Dominated Community This highly disturbed community is dominated by cultivated corn fields and maintained roadsides. Many of the plants found here in addition to corn plants are weedy species adapted to disturbed, maintained areas. The frequently mowed roadside is dominated by fescue grass (Festuca spp.). Other herbaceous species here include red clover (Trriiolium pratense), elephants foot (Elephantopus tomentosus), dandelion (Taraxacum officinale) and dayflower (Commelina communis). The less frequently maintained road right-of-way and the drainage ditch between the roadside and the cornfield is dominated by tall weedy herbs, vines, shrub, and tree sprouts. Herbaceous species 11 include Johnson grass (Sorghum halepense), yarrow (Achillea millefolium), jewel-weed (Impatiens cca ensis), wingstem (Verbesina occi enta is), wild lettuce Lactuca f of ridana), pokeweed (Pacca americana), knotweed (Pohl gon?um pennsylvanicum), ragweeds (Ambrosia tri- fida; A. artemisiifo lia), golden rods (Solidago spp.), tearthumb (Pol onum sa ittatum), purple-stem aster (Aster uniceus), ironweed (Vernonia noveboracensis), and Joe-Pye-weed (Eupatorium fistulosum). Vines present include Japanese honeysuckle (Lonicera Japonica), poison ivy (Toxicodendron radicans), Virgins bower (Clematis virginiana), climbing buckwheat (Pol onum convolvulus), grape (Vitis sp.), cane (Arundinaria gigantea)dock (Arctium minus), greenbrier (Smilax spp.), bouncing Bet (Saponaria officinal), and trumpet vine (Campsis radicans). Shrubs include blackberry (Rubus sp.), privet (Ligustrum sinense), staghorn sumac (Rhus typhina), smooth sumac (Rhus lg abra), and elderberry (Sambucus canadensis). Tree species occurring as sprouts in cut-over areas and a few mature individuals along the edge of the creek include: box elder (Acer negundo), river birch (Betula nigra), sycamore (Platanus occidentalis), black walnut (Juglans nigra), poplar (fir odendron to ipifera), and black cherry (Prunus serotina). Resident animal species would be few in these disturbed areas. However, many opportunistic species which may reside in nearby communities would utilize these areas for feeding zones. Seeds, berries, fruits, and insects, as well as living and dead animal matter, attract a wide variety of foraging animals including: eastern cottontail (Sylvilagus floridanus), opossum (Didelphis virginiana), wood chuck (Marmota monax), white-tailed deer (Odocoileus virginianus), white-footed mouse (Peromyscus leuc)pus) ,_ s-pic cotton rat (Sigmodon hispidus), and raccoon (Procyon lotor). Birds likely to visit the area are American crow (Corvus brachyrhychos), barn swallows (Hirundo rustica), carolina chickadees (Parus carolinensis), mourning dove (Zenaida macroura), carolina wre_n_TThryot orus ludovicianus), common grackle (uiscalus quiscula), and cardinal (Carding is cardinalis). Roadkills may attract scavenging animals such as turkey vultures (Catharter aura), common crows, and opossums. Reptiles and ampans, including toads, box turtles, snakes, and lizards, may sun themselves on the roadsides or crawl onto the warm road surface at night. These may include American Toad (Bufo americanus), eastern box turtle (Terrapene carolina), black racer snake (Coluber constrictor), eastern hognose snake (Heterodon platyrhinos), and five-lined skink (Eumeces fasciatus). b. Aquatic Communities Aquatic invertebrates are a major component of stream ecosystems as primary and secondary consumers and as prey species for organisms higher in the food chain. Aquatic invertebrates, including crayfish Cambaridae sp.), and some insects are present in Kings Creek. However, their numbers are limited by the heavy siltation that would tend to clog gills and smother bottom-dwelling invertebrates in this stream. 12 Amphibian and reptile species likely to occur in and around this stream include snapping turtle (Chel drara ser entina), northern water snake (Nerodia sipedon), and green frogs (Rana clamitans). According to Joe Mickey, N.C. Fisheries Biologist, the most likely fish species to occur in Kings Creek include: bluehead chub (Nocomis leptocephalus), fantail darter (Etheostoma flabellare), rosyside dace (Clinostomus funduloides), and white sucker (Catostomus commersoni). Other fish that have been reported from this area of the Yadkin River drainage include: highback chub (Hybopsis hypsinotus), redlip shiner (Notropis chiliticus), fiery black shiner (Notropis rrhomelas), northern hog sucker (H entelium nigricans), striped Jumprocc Moxostoma rupiscartes), an margined madtom (Noturus insignis). C. Anticipated Impacts: Biotic Communities Biotic community impacts resulting from the project construction are being addressed separately as terrestrial impacts and aquatic impacts. However, it is important to remember that construction impacts may not be restricted to the community in which the construction activity occurs. All measures possible should be taken to ensure no sediment leaves the construction site. Terrestrial Impacts Most of the project area has been highly disturbed by previous roadway construction and agricultural fields. New fill would be required for either Alternative 1 (temporary detour construction) or Alternative 2 (permanent realignment of roadway), thereby increasing the risk of soil erosion. Alternative 3 would replace the bridge in its present location with road closure and would result in the least new disturbance. The proposed right-of-way width of all alternates would be 18.3 m (60 feet). Construction will result in the loss and displacement of some plant and animal life, regardless of the alternative chosen. However, previous disturbance at this site has already limited plant and animal species, so the impact will also be limited. The anticipated area to be impacted within this community is presented for each alternative in Table 1. Table 1. Anticipated Impacts to the Biotic Community (Man-Dominated Community) Alternative 1 Alternative 2 Alternative 3 tare/acre 0.7/1.8 0.9/2.3 0.3/0.7 * Alternative 1 impacts include those of the proposed temporary detour. 13 Aquatic Community Project construction is likely to temporarily increase sediment loads in this already heavily silted creek. Construction-related sedimentation can be harmful to local populations of invertebrates which are important to aquatic, and some terrestrial, food chains. Less mobile species, such as filter feeders, may be covered and smothered by substrate disturbance and sedimentation resulting from construction related erosion. Increased sediment loads and suspended particulates may smother fish eggs, reduce oxygen-carrying capacity, and raise water temperatures.' Contact with wet cement will also affect water quality and aquatic organisms. If spawning habits or habitats are altered, it could affect game fish populations in the Yadkin River. The close proximity of the Yadkin River, which is located approximately 1.6 km (1 mile) downstream, increases the possibility that erosion at this construction site could also increase sediment loads in the river. Bridge construction will be accomplished so that wet concrete does not come in contact with creek water to reduce the possibility of a fish kill. Other concerns at this site would be the possibility of increased concentrations of toxic compounds (gasoline, oil, etc.) reaching the stream from construction machinery or run-off from the new bridge. Best Management Practices (BMPs) for protection of surface waters will be strictly followed to protect the biological integrity and water quality at this site. 4. Jurisdictional Issues a. Waters of the United States Wetlands and surface waters fall under the broad category of Waters of the United States as defined in 33 CFR 328.3 and in accordance with provisions of section 404 of the Clean Water Act (33 U.S.C. 1344) and are regulated by the U.S. Army Corps of Engineers (C.O.E.). Potential wetland communities were evaluated using the criteria specified in the 1987 U.S. Army Corps of Engineers Wetlands Delineation Manual. For an area to be designated wetlands, the following three specifications must be met: 1) presence of hydric soils, 2) presence of hydrophytic vegetation, and 3) evidence of hydrology, or hydrological indicators, including: saturated soils, stained oxidized rhizospheres, matted vegetation, high water marks on trees, buttressed tree bases, and surface roots. No wetland communities are located within the proposed right of way limits of the studied alternatives. Construction of the proposed project will have no impacts on any jurisdictional wetlands. 14 Permits Construction is likely to be authorized by provisions of General Nationwide permit 33 CFR 330.5 (a) (23). Caldwell County is one of 25 counties designated as having trout waters. Projects in these counties must be reviewed and approved by the North Carolina Wildlife Resources Commission prior to the issuance of the COE permit. Also, Section 401 of the Clean Water Act (CWA) requires that the state issue or deny water quality certification for any federally permitted or licensed activity that may result in a discharge to the waters of the United States prior to issuance of COE permits. In her November, 1993 letter, included in the Appendix (see page A-4), the North Carolina Wildlife Resources Commission's Mountain Region Coordinator, Stephanie E. Goudreau, stated that trout do not occur at this project site, and there are no other known special concerns. Mitigation Since this project will likely permit, mitigation for impacts to required by the Corps of Engineers. mitigation requirements, however, r b. Rare or Protected Species be authorized under a Nationwide surface waters is generally not A final determination regarding ests with Corps of Engineers. Federal law requires that any action, which has the potential to have a detrimental impact to the survival and well-being of any species classified as federally protected, is subject to review by the FWS and/or the National Marine Fisheries Service under the provisions of the Endangered Species Act (ESA) of 1973, as amended. Endangered species receive additional protection under separate state statutes. In North Carolina, protection of plant species falls under N.C. General Statutes (G.S.) 106-202.12 to 106-202.19 of 1979. Wildlife protection falls under G.S. 113-331 to 113-337 of 1987. 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 of 1973, as amended. The Fish and Wildlife Service (FWS) lists four (4) federally protected species for Caldwell County as of April 6, 1995. These species are listed in Table 2. 15 Table 2. Federally Protected Species - Caldwell County SCIENTIFIC NAME COMMON NAME STATUS * Mirohexura montivaga Spruce-fir moss spider E Geu- m rad atum Spreading avens E L ai triis' heTT-eri Hel1ers blazing star T Soago spit-it-iamaea Blue Ridge goldenrod T * E denotes Endangered (a species that is threatened with extinction throughout all or a significant portion of its range.) T denotes Threatened (a species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.) Mirohexura montivaga (Spruce-fir moss spider) E Animal Family: Dipluridae Federally Listed: March, 1994 Distribution in N.C.: Avery, Caldwell, Swain The spruce-fir moss spider is a very small spider. Adults measure only 3.0 to 5.6 mm (1/4 - 7/16 in). Coloration ranges from light brown to a darker reddish brown, and there are no markings on the abdomen. The carapace is generally yellowish brown. The most reliable field identification characteristics for the spruce-fir moss spider are a pair of very long posterior spinnerets and the presence of a second pair of book lungs, which appear as light patches posterior to the genital furrow. The typical habitat of this spider is found in well-drained moss (and liverwort) mats growing on rocks or boulders in well-shaded situations in mature, high-elevation Fraser fir and red spruce forests. No critical habitat has been designated. BIOLOGICAL CONCLUSION: NO EFFECT The study area does not contain suitable habitat for the spruce-fir moss spider. No impact to this species will occur from proposed construction. Geum radiatum (Spreading avens) Plant Family: Rosacea Date Listed: April 5, Flowers Present: June Distribution in N.C.: Mitchell, Stokes, E 0 1990 -early July Ashe, Avery, Transylvania, Buncombe, Burke, Caldwell, Watauga, Yancey. Spreading avens is a perennial herb having stems with an indefinite cyme of bright yellow radially symmetrical flowers. Flowers of spreading avens are present from June to early July. 16 Spreading avens has basal leaves which are odd-pinnately compound; terminal leaflets are kidney shaped and much larger than the lateral leaflets, which are reduced or absent. Spreading avens is found only in the North Carolina and Tennessee sections of the Southern Appalachian Mountains. Spreading avens occurs on scarps, bluffs, cliffs, and escarpments on mountains, hills, and ridges. Known populations of this plant have been found to occur at elevations of 1535-1541 meters (5060-5080 feet), 1723-1747 meters (5680-5760 feet), and 1759 meters (5800 feet). Other habitat requirements for this species include full sunlight and shallow acidic soils. These soils contain a composition of sand, pebbles, humus, sandy loam, clay loam, and humus. Most populations are pioneers on rocky outcrops. BIOLOGICAL CONCLUSION: NO EFFECT No habitat exists in the project study area for the spreading avens. It can be concluded that the subject project will not impact this Endangered species. Liatris helleri (ReT ers blazing star) T Plant Family: Asteraceae Federally Listed: November 19, 1987 Flowers Present: Late June - August Distribution in N.C.: Ashe, Avery, Burke, Caldwell, Mitchell, Watauga This plant is endemic to high elevation ledges of rock outcrops of the northern Blue Ridge Mountains in North Carolina. Of nine historic populations, only seven remain in existence. Hellers blazing star is a short, stocky plant that has one or more erect stems that arise from a tuft of narrow, pale green basal leaves. Leaves are acuminate and diminish in size and breadth upward on the stem. Stems are 0.4 m (16 inches) tall and are topped with a raceme of small 0.1-0.2 m (4-8 inches) lavender flowers. Fruits are present from September to November. This plant is a high altitude early pioneer species and can be found growing on high elevation ledges of rock outcrops in grassy areas where it is exposed to full sunlight. It prefers shallow acid soils associated with granite rocks. BIOLOGICAL CONCLUSION: NO EFFECT The study area does not support suitable habitat for Hellers blazing star. No impacts to Hellers blazing star will occur from proposed construction. 17 Solidago spithamaea (Blue Ridge Goldenrod) T Plant Family: Asteraceae Federally Listed: April 29, 1985 Flowers Present: July to September Distribution in N.C.: Avery, Caldwell, Mitchell Blue Ridge goldenrod is an erect perennial herb 1-4 dm (4-16 inches) tall that arises from a short stout rhizome. The yellow flowers are borne in heads arranged in a corymbiform inflorescence. Calyx is represented by a pappus of numerous, capillary, upwardly barbellate white bristles, 2.5-3.5 mm long. Solidago spithamaea grows above 1400 m (4,600 ft) in dry rock crevices of granite outcrops on the high peaks of the Blue Ridge Mountains. No critical habitat has been designated for Blue Ridge goldenrod. BIOLOGICAL CONCLUSION: NO EFFECT The study area does not contain suitable habitat for this species. No impact to Blue Ridge goldenrod will occur from proposed construction. C. Federal Candidate and State Protected Species There are eight (8) Federal Candidate 2 (C2) species listed for Caldwell County. Candidate 2 (C2) species are defined as taxa for which there is some evidence of vulnerability, but for which there are not enough data to warrant a listing of Endangered, Threatened, Proposed Endangered, or Proposed Threatened at this time. These species are mentioned here for informational purposes, should they become protected in the future. Table 3 lists these federal candidate species. The North Carolina status of these species is also listed in Table 3. Plants or animals with state designations of Endangered (E), Threatened (T), or Special Concern (SC) are given protection by the State Endangered Species Act and the N.C. Plant Protection and Conservation Act of 1979, administered and enforced by the North Carolina Wildlife Resources Commission and the North Carolina Department of Agriculture. 18 Table 3.

Threatened species are those likely to become an endangered species in the state if not protected. SC = Special Concern. A species of plant in North Carolina that requires monitoring. These may be collected from the wild and sold under specific regulations. C = Candidate. Species which are rare in North Carolina for various reasons and are likely to merit listing as Endangered or Threatened if they continue to decline. SR = Significantly Rare. Species very rare in N.C. whose numbers are significantly reduced by habitat destruction, disease, or direct exploitation. Usually more common somewhere else in their range. Surveys for these species were not conducted during site visits, nor were any of these species observed. D. Air Quality and Traffic Noise The bridge replacement project is located within the jurisdiction for air quality of the Winston-Salem Regional Office of the North Carolina Department of Environment, Health, and Natural Resources. The proposed project is located in Caldwell County, which has been determined to be in compliance with the National Ambient Air Quality Standards. 40 CFR part 51 is not applicable, because the 19 proposed project is located in an attainment area. This project is not anticipated to create any adverse effects on the air quality of this attainment area. The project involves the removal and replacement of Bridge Number 40 on SR 1552 over Kings Creek. No additional through lanes are planned, and the project will not substantially increase traffic volumes. Due to the aforementioned factors and low anticipated future traffic, the project's impact on noise and air quality will be insignificant. Noise levels could increase in the area during construction, but this increase 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 for highway traffic noise (23 CFR Part 772) and for air quality (1990 CAAA and NEPA), and no additional reports are required. E. Flood Hazard Evaluation Caldwell County is a participant in the National Flood Insurance Regular Program. Kings Creek is not included in a detailed flood study. A copy of the Flood Insurance Rate Map with the approximate limits of the 100-year floodplain is included as Figure 4. The floodplain in the vicinity of the project is rural and wooded with mostly agricultural uses. There are no buildings in the project vicinity with floor elevations below the 100-year floodplain. The proposed bridge replacement will not adversely affect the floodplain. F. Relocations No businesses or residences will be relocated as part of the proposed project. G. Hazardous Materials No hazardous waste sites were identified in the project vicinity. H. Section 4(f) Properties The proposed project will not impact any properties eligible for protection under Section 4(f) of the Department of Transportation Act of 1966. X. CONCLUSION Bridge Number 40 on SR 1552 (Grandin Road) over Kings Creek in Caldwell County will be replaced at its existing location with a 55 m (180-foot) bridge. A temporary on-site detour including a 23 m (75-foot) detour bridge located 10 m (30 feet) north of the existing bridge is also recommended. 20 No substantial environmental impacts are anticipated as a part of this project, therefore, the proposed project is considered to be a "categorical exclusion" as defined by the Federal Highway Administration's environmental guidelines (23 CFR 771.117).

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 and for our use afterwards. 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 the following historic structures in the general project area: Grandin Baptist Church. On SR 1573 just west of the junction with SR 1562. There are no known recorded archaeological sites within the project boundaries. However, the project area has never been systematically surveyed to determine the location of significance of archaeological resources. The floodplain in which Bridge 40 is located is considered to be of high probability for the location of archaeological sites. We recommend that a comprehensive survey be conducted by a NCDOT archaeologist to identify the presence and significance of archaeological remains that may be damaged or destroyed by the proposed bridge. Potential effects on unknown resources should be assessed prior to the initiation of construction activities. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which indicates how NCDOT addressed our comments.

Due to temporary staffing shortages, the North Carolina Wildlife Resources Commission (NCWRC) will be unable to send a representative to the scoping meeting for this project. Kings Creek is somewhat degraded and does not support trout in the project area; therefore, trout are not an issue to the NCWRC. However, we anticipate commenting on this project through the 404 permit process because Caldwell County is considered a trout county by the U.S. Army Corps of Engineers. Our comments will reflect that this stream does not support trout. Thank you for the opportunity to provide planning stages for this project.

SAMUEL HUNT I I I SECREEARY SUBJECT: Scoping Meeting for replacing Bridge Number 40 on Grandin Road (SR 1552) over Kings Creek, Caldwell County, State Project No. 8.2731901, Federal Aid Project No. BRZ-1552(4), T.I.P. Project B-2525 On November 16, 1993 at 10:00 A.M., a Scoping meeting for T.I.P. Project B-2525 was held in Room 558-A of the Highway Building. At the meeting, alternatives for replacing Bridge Number 40 in Caldwell County were discussed. The following people were in attendance: Eric Galamb Melba McGee Robin Stancil Sid Autry, P.E. Brian Williford Darin Wilder Roy Girolami Leroy Smith, P.E. Cynthia Joyner Teresa Hart Eddie McFalls NCDEHNR-DEM NCDEHNR-Policy Development NCDCR-SHPO Location and Surveys Hydraulics Program Development Structure Design Roadway Design Roadway Design Planning and Environmental Planning and Environmental The meeting was opened with a description of the schedule for T.I.P. Project B-2525. The project is scheduled for right of way in March of 1995 and is scheduled for construction in March of 1996. The T.I.P. funds $18,000 for right of way and $625,000 for construction. A Categorical Exclusion will be completed for the project in July of 1994. Next, the existing conditions of Kings Creek, Bridge Number 40, and the approaches on Grandin Road (SR 1552) were described. Traffic and accident data were also discussed. Information presented on each of these subjects is listed below: November 22, 1993 Page 2 Bridge Information Length: 42.1 m (140 feet) Width: 5.8 m (26 feet) Height Crown to Bed: 5.5 m (18 feet) Structure: Timber floor on I-beams and timber joists; Bents are timber caps on timber posts and piles. The bents are concrete encased. Year Constructed: 1966 Present Posting: SV-10 tons / TTST-18 tons Present Condition: Poor Sufficiency Rating: 16.0 Estimated Remaining Life: 1 year The existing bridge has had scour problems. Approach Information Bridge Number 40 lies on a tangent section of Grandin Road (SR 1552). Grandin Road (SR 1552) has a statutory speed limit of 55 mph. In the vicinity of the bridge, Grandin Road (SR 1552) has 4.9 m (16 feet) of pavement with grassed shoulders which vary from 1.2 m (4 feet) to 2.4 m (8 feet) in width. Along the east side of Grandin Road, Southern Bell has an underground telephone line which will require relocating. Kin s Creek Just west of Grandin Road (SR 1552), Kings Creek runs parallel to the roadway for approximately 25 m (82 feet). The approach fill is protected from this meander with riprap. In the past, Bridge Number 40 has had scour problems. Caldwell County is a trout county. Prior to the scoping meeting, however, Stephanie Goudreau of the Habitat Conservation Program of the North Carolina Wildlife Resources Commission wrote: "Kings Creek is somewhat project area; therefore, trou anticipate commenting on this Caldwell County is considered Engineers. Our comments will trout." degraded and does t are not an issue project through t a trout county by reflect that this not support trout in the to the NCWRC.

Three school buses presently use Grandin Road twice daily. November 22, 1993 Page 3 After the existing conditions were presented, Brian Williford opened the discussion of alternatives for replacing the bridge with the Hydraulic Unit's recommendations. The Hydraulics Unit recommended Bridge Number 40 be replaced in its existing location and a 23 m (75-foot) temporary detour structure be constructed approximately 10 m (33 feet) downstream of the existing bridge. Kings Creek is narrow at this location and could be bridged at an elevation as much as 1.2 m (4 feet) lower than the existing bridge. The Hydraulics Unit proposed Bridge Number 40 be replaced with a 55 m (180-foot) structure. This longer structure could be used to help accommodate the existing meander in Kings Creek. Based on the traffic on the bridge and the statutory 55 mph speed limit (60 mph design speed), the width of Bridge Number 40 was proposed as 7.9 m (26 feet). The Hydraulics Unit also recommended a cleanout of Kings Creek in the immediate vicinity of the proposed bridge. Leroy Smith of Roadway Design, citing Stephanie Goudreau's written statement regarding trout waters which was presented at the meeting's opening, suggested a channel change to remove the meander. This channel change would facilitate a shorter structure length and thus save money. Eric Galamb then stated that the Division of Environmental Management would not support the channel change. He stated that the North Carolina Department of Transportation must protect future uses of the stream. He also stated that although trout may not be present in this area of Kings Creek at this time, impacts to the stream must be kept to a minimum so it may be inhabitable by trout in the future. After this discussion, Division's recommendations were presented. Before the meeting, Wally Bowman, Division Construction Engineer, stated that the Division does not support road closure as an alternative. The Division recommends the use of a temporary detour structure and the replacement of Bridge Number 40 at its existing location. The replacement of Bridge Number 40 at its existing location would maintain the existing tangent section of SR 1552. No suitable routes are available for detouring traffic. An off-site detour would involve more than 5.6 km (3.5 miles) of unpaved roads. The only improved route is more than 22 km (13 miles) long. Road closure would greatly inconvenience school bus traffic as well as local farmers who own land on both sides of Kings Creek and regularly cross Bridge Number 40. Next, the vegetation along the banks of Kings Creek was discussed. Photographs of the vegetation which included shrubs, brush, and trees were circulated in the meeting. Eric Galamb mentioned that the presence of vegetation influences the water temperature of the stream and should be replaced once the bridge project is complete. Water temperatures affect the types of fish and other aquatic organisms which use the stream. Moreover, Eric Galamb stated that the timing of construction should be coordinated with the North Carolina Wildlife Resources Commission to minimize stream impacts. After the discussion of the vegetation, Brian Williford stated that Bridge Number 40 is not in a Federal Regulatory Floodway. The area, however, is affected by backwater from the Yadkin River. Brian Williford's final comments were that no wetlands are in the project vicinity and erosion control measures should be coordinated with environmental agencies. November 22, 1993 Page 4 Robin Stancil then described the architectural and archaeological resources in the area. Grandin Baptist Church is not on the National Register of Historic Places but is considered historic and is eligible for the Register. Robin, however, stated that as long as the church lands do not extend any further than its driveway or Howell Farm Road (SR 1513), Grandin Baptist Church will not be within the Area of Potential Effect for this project. Since the bridge is within the floodplain of the Yadkin River, Robin Stancil stated that there is a high probability for archaeological sites. An archaeological survey of the project area will be required. Leroy Smith then asked Roy Girolami from Structure Design how long it would take to construct the new bridge. Roy Girolami said one construction season would probably suffice. Construction of the new bridge would take approximately 6 months. Thus, the temporary detour would remain in place approximately 9 months (additional time to allow for approach work). Other alternatives for replacing Bridge Number 40 were also discussed including a relocation alternative which would involve constructing the proposed bridge east of the existing bridge. The horizontal curve on the southern approach could be used to shift the alignment. On the northern approach, however, two new curves would have to be introduced into the alignment of Grandin Road (SR 1552). Roadway Design will provide cost estimates for this alternative as well as the temporary detour alternative. EBM/plr cc: Lubin Prevatt, P.E. Wilson Stroud
