Federal Aid Project No. MABRZ-1984(2), State Project No. 8.2851901, TIP Project No. B-3312. Please find enclosed three copies of the project planning report for the above referenced project. This project involves the proposed replacement of Bridge No. 347 on SR 1984 over Laurel Creek in Burke County. The existing bridge will be replaced with a double-barrel box culvert, with each barrel 12 feet x 9 feet, on existing alignment. Project length is 286 feet, and the proposed roadway will have a 20-foot paved surface and 4-foot grass shoulders. The existing bridge is composed entirely of timber and steel and will result in no temporary fill due to bridge demolition debris. NCDOT's Best Management Practices for Bridge Demolition and Removal will be followed during demolition of the existing bridge. Traffic will be maintained on a temporary on-site detour during construction. This detour will be located approximately 50 feet west of the existing structure, and will utilize two 96-inch corrugated metal pipes to maintain the flow of Laurel Creek. M -p C_') -bG M M M C7 --i No wetlands are contained within the proposed project limits; however, temporary and permanent impacts to jurisdictional surface waters are anticipated. Temporary impacts to Laurel Creek from the detour will be 75 linear feet and permanent impacts from the proposed culvert will be 62 linear feet. In addition, there will be a 35-foot channel relocation at the culvert outlet. An intermittent stream channel was identified after the completion of the planning document, and will have temporary and permanent impacts. This intermittent stream flows into Laurel Creek just 'vest of the existing bridge, and parallels SR 1984 (see attached plan view). Temporary impacts due to detour fill will be 65 linear feet and permanent impacts due to proposed piping will be 55 linear feet. This project is being processed by the Federal Highway Administration as a "Categorical Exclusion" in accordance with 23 CFR 771.115(b). Therefore, we do not anticipate requesting an individual permit, but propose to proceed under Nationwide Permit 23 in accordance with the Federal Register of December 13, 1996, Part VII, Volume 61, Number 241. We anticipate a 401 General Certification will apply to this project, and are providing one copy of the CE document to the North Carolina Department of Environment and Natural Resources, Division of Water Quality, for their review. This project will take place in a mountain trout county. Thus we anticipate that comments from the North Carolina Wildlife Resources Commission (NCWRC) will be required. By copy of this letter and attachment, NCDOT hereby requests NCWRC review. We request that the NCWRC forward their comments to the US Army Corps of Engineers. If you have any questions or need additional information please call Ms. Sue Brady at (910) 733-1143. r cerely, ".,-D ?- ! cJQ ? (;v) William D.

It is programmed in the Draft 2000-2006 Transportation Improvement Program (TIP) as a bridge replacement project. This project is part of the Federal Highway Bridge Replacement and Rehabilitation Program (HBRRP) and has been classified as a "Categorical Exclusion". No substantial environmental impacts are expected. I. SUMMARY OF RECOMMENDATIONS Bridge No. 347 will be replaced with a two-barrel box culvert on the existing alignment (see Figure 2). Each barrel of the box culvert will be 2.7 x 2.7 meters (9 x 9 feet). Traffic will be maintained on a temporary alignment 15 meters (50 feet) west of the existing structure. The project length is 61 meters (200 feet) (see Figure 2). The pavement width will be 6.0 meters (20 feet) including two 3.0-meter (10-foot) lanes. The grass shoulders will be 1.2 meters (4 feet) wide. Based on preliminary design, the design speed should be approximately 50 km/h (30 mph). The pavement width on the temporary alignment will be 5.4 meters (18 feet). The width of the grass shoulders will be 1.2 meters (4.0 feet). Two 1800-millimeter (72- inch) corrugated metal pipes will maintain the flow in Laurel Creek during construction. The design speed for the detour alignment will be 30 km/h (20 mph). The estimated cost of the project is $420,000 including $375,000 in construction costs and $45,000 in right of way costs. The estimated cost shown in the Draft 2000- 2006 TIP is $355,000; including $328,000 in construction costs, and $27,000 in right of way costs. II. SUMMARY OF ENVIRONMENTAL COMMITMENTS All standard procedures and measures will be implemented to avoid or minimize environmental impacts. All practical Best Management Practices (BMP's) will be included and properly maintained during project construction. In accordance with the provisions of Section 404 of the Clean Water Act (33 U.S.C. 1344), a permit will be required from the Corps of Engineers for the discharge of dredged or fill material into "Waters of the United States." North Carolina Division of Water Quality (DEM) Section 401 Water Quality General Certification will be obtained prior to issue of the Army Corps of Engineers Nationwide Permit # 23. Foundation investigations will be required on this project. The investigation will include test borings in soil and/or rock for in-site testing as well as obtaining samples for laboratory testing. This may require test borings in streams and/or wetlands. NCWRC has commented that Laurel Creek is not Designated Public Mountain Trout Waters. NCWRC has no special concerns regarding this project. III. ANTICIPATED DESIGN EXCEPTIONS NCDOT anticipates that a design exception may be necessary due to horizontal and vertical alignment. The topography of the project makes it impossible to improve horizontal or vertical alignment without significant blasting into the mountain on the south approach to the bridge. IV. EXISTING CONDITIONS SR 1984 is classified as a Rural Local route in the Statewide Functional Classification System. Traffic volume is 300 vehicles per day (VPD) and projected at 600 VPD for the year 2020. There is no posted speed limit on SR 1984 in the vicinity of the bridge. The land along SR 1984 is a mixture of undeveloped land with pockets of residential development. The existing bridge was completed in 1963. It is 11 meters (36 feet) long. The deck is 6.1 meters (20 feet) wide. There is approximately 3.4 meters (11 feet) vertical clearance between the bridge deck and streambed. There are two lanes of traffic on the bridge. According to Bridge Maintenance Unit records, the sufficiency rating of the bridge is 14.8 out of a possible 100. Presently the bridge is posted with weight restrictions of 12 tons for single vehicles and 16 tons for truck-tractor semi-trailers. The vertical alignment near the bridge is fair. Immediately south of the bridge the road begins to climb quickly. The horizontal alignment as shown in Figure 2 is fair. Shoulders on both approaches of the bridge are approximately 1.0 meter (3 feet) wide. The Traffic Engineering Branch indicates that two accidents have been reported in the period from May 1994 to April 1997 in the vicinity of the project. The accidents were not the result of the bridge or the alignment. There are 8 daily school bus crossings over the studied bridge. The Transportation Director noted that the crossing was the only access to SR 1984 and assumed that some provision would be made to leave the road open. There are aerial power and telephone utilities in the project vicinity but it is uncertain as to what might be affected by the project. Even so, utility impacts would be considered low. V. PROPOSED ALTERNATIVES One build alternative was fully evaluated during the planning process. Bridge No. 347 will be replaced on the existing location. Traffic will be maintained on a temporary alignment during construction. Detouring traffic is not possible because SR 1984 is a dead end road. Realigning SR 1984 along the proposed detour route and maintaining traffic on the existing structure during construction would have required a curved approach to the intersection or a skewed intersection. This would potentially create a hazard not currently experienced by travelers trying to turn onto NC 18. Because of topography and buildings, all other considerations would have been far more costly and environmentally damaging than the option chosen. "Do-nothing" is not practical, requiring the eventual closing of the road as the existing bridge completely deteriorates. Rehabilitation of the existing deteriorating bridge is neither practical nor economical. VI.

RECOMMENDED IMPROVEMENTS Bridge No. 347 will be replaced as with a two-barrel box culvert on the existing alignment (see Figure 2). Each barrel of the box culvert will be 2.7 x 2.7 meters (9 x 9 feet). Traffic will be maintained on a temporary alignment 15 meters (50 feet) west of the existing structure. The project length is 61 meters (200 feet) (see Figure 2). The pavement width will be 6.0 meters (20 feet) including two 3.0-meter (10-foot) lanes. The grass shoulders will be 1.2 meters (4 feet) wide. Based on preliminary design, the design speed should be approximately 50 km/h (30 mph). The pavement width on the temporary alignment will be 5.4 meters (18 feet). The width of the grass shoulders will be 1.2 meters (4.0 feet). Two 1800-millimeter (72- inch) corrugated metal pipes will maintain the flow in Laurel Creek. The design speed for the detour alignment will be 30 km/h (20 mph). Because all other possible alternates would have been far more expensive and more environmentally damaging, the recommended improvement is the only reasonable and feasible choice. VIII. ENVIRONMENTAL EFFECTS A. GENERAL This project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. This project is considered to be a "Categorical Exclusion" due to its limited scope and insignificant environmental consequences. This bridge replacement will not have a substantial adverse effect on the quality of the human or natural environment by implementing the environmental commitments listed in Section II of this document in addition to use of current NCDOT standards and specifications. The project is not in conflict with any plan, existing land use, or zoning regulation. No change in land use is expected to result from construction of this project. There are no hazardous waste impacts. No adverse effect on families or communities is anticipated. Right-of-way acquisition will be limited. No adverse effect on public facilities or services is expected. The project is not expected to adversely affect social, economic, or religious opportunities in the area. There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of national, state, or local significance in the vicinity of the project. The proposed bridge replacement project will not raise the existing flood levels or have any significant adverse effect on the existing floodplain. Utility impacts are considered to be low for the proposed project. B. AIR AND NOISE This project is an air quality "neutral" project, so it is not required to be included in the regional emissions analysis and a project level CO analysis is not required. The project is located in Burke 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 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 will not substantially increase traffic volumes. Therefore, it will not have substantial impact on noise levels. Temporary noise increases may occur during construction. C. LAND USE & FARMLAND EFFECTS In compliance with the Farmland Protection Policy Act (FPPA) of 1981, the project was evaluated for impacts to prime or important farmland soils. The project will have no impacts to prime or important farmland soils. D. HISTORICAL EFFECTS & ARCHAEOLOGICAL EFFECTS Upon review of area photographs, aerial photographs, and cultural resources databases, the State Historic Preservation Office (SHPO) has recommended that neither an architectural or archaeological survey is required. E. NATURAL RESOURCES Physical Resources Water and soil resources, which occur in the study area, are discussed below. The availability of water and soils directly influence composition and distribution of flora and fauna in any biotic community. Water Resources Field surveys revealed that one body of surface water is located within the project area. The Division of Water Quality (DWQ) has assigned index numbers for streams and tributaries in North Carolina. One perennial stream in the Catawba River Basin, Laurel Creek [DWQ Index No. 11-129-1-13, (3/1/62)] is crossed by SR 1984. This stream carries a Best Usage Classification of Class C. Class C refers to waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The stream flow of Laurel Creek was moderate at the time of field visit. The stream was approximately 3.6 meters (12 feet) in width with an average channel width of 6.1 meters (20 feet). The stream was approximately 0.46 meters (1.5 feet) deep. The substrate consisted of sand, silt, and cobble. Point sources refer to discharges that enter surface water through a pipe, ditch, or other defined points of discharge. The term most commonly refers to discharges associated with wastewater treatment plants. Point source dischargers located throughout North Carolina are permitted through the National Pollutant Discharge Elimination System (NPDES) program. Any discharger is required to register for a permit. There is one NPDES site located within 1.6 kilometers (1.0 mile) upstream of the project study area. Permit No. NCG550655 was issued on 2/10/94 to the Laurel Creek Mobile Home Park. This permittee discharges into Laurel Creek approximately 1823 meters (5981 feet) upstream of the project area. Non-point source refers to runoff that enters surface waters through stormwater flow or no defined point of discharge. There are many types of land use activities that can serve as sources of nonpoint source pollution including land development, construction, crop production, animal feeding lots, failing septic systems, landfills, roads, and parking lots. Sediment and nutrients are major pollution-causing substances associated with nonpoint source pollution. Others include fecal coliform bacteria, heavy metals, oil and grease, and any other substance that may be washed off the ground or removed from the atmosphere and carried into surface waters. The Benthic Macroinvertebrate Ambient Network (BMAN) is managed by DWQ and is part of an ongoing ambient water quality monitoring program which addresses long term trends in water quality. The program assesses water quality by sampling for selected benthic macroinvertebrate organisms at fixed monitoring sites. Some macroinvertebrates are sensitive to very subtle changes in water quality; thus, the species richness and overall biomass of these organisms are reflections of water quality. There are no BMAN sites within the project vicinity. Soils and Topography The Cliffside series is the dominant soil series occurring at the project site (Table 1). The Cliffside series consists of soils on upland ridges and side slopes. The Udorthents series consists of areas where the natural soils have been altered by digging, grading, or filling, to the extent that individual soil types can no longer be recognized. Table 1.

BIOTIC RESOURCES Terrestrial Communities Three terrestrial communities, maintained roadside, riparian fringe, and residential/business, exist within the project area, and will be impacted by the subject project. The maintained roadside community consists of the highly maintained shoulders and some less intensively managed areas that grade into the surrounding natural communities. Significant soil disturbance and compaction, along with frequent mowing or herbicide application, keep this community in an early successional state. Dominant plants in the heavily maintained portions of the roadside community include fescue and plantain. In the areas that receive lower levels of maintenance, more diverse communities can develop. Japanese honeysuckle, dog fennel, bush clover, grape, Southern lady fern, ragweed, pokeweed, poison oak, and smooth sumac populate this community. A N A residentialibusiness community exists in the location of the proposed temporary bridge and road. This community includes the following species: fescue, winged elm, mimosa, Canada hemlock), white pine, ragweed, Southern lady fern, and smooth sumac. The riparian edge community included herb and vine species such as poison ivy, jewelweed, elderberry, Virginia creeper, rosebay and Christmas fern. Trees found in this community are white oak, red maple, tulip poplar, black gum, black cherry, dogwood, sycamore, sweet gum, and tree-of-heaven. Wildlife found in these communities is limited and consists primarily of wide-ranging, adaptable species, which are well suited to coexistence with human development. Mammals common to disturbed edge areas, such as eastern cottontail rabbit, raccoon, white-tailed deer, and gray squirrel may inhabit forested fringes. The most common reptiles found in such habitats are eastern box turtle and predators such as black racer, and eastern garter snake. Birds likely to frequent such habitats include common crow, American robin, mourning dove, and European starling. Freshwater fishes likely to be found in creeks such as Laurel Creek may include creek chub, redbreast sunfish, white shiner, and rosyside dace. Summary of Anticipated Impacts Construction of the proposed project will have various impacts on the biotic resources described. This section quantifies and qualifies potential impacts to the natural communities within the project area in terms of the area impacted and the organisms affected. Temporary versus permanent impacts are considered as well, along with ??recommendations to minimize or eliminate impacts. ,Anticipated Impacts to Terrestrial Communities Impacts to terrestrial communities will result from project construction due to the clearing and paving of portions of the project area, and thus the loss of community area. Calculated quantitative impacts to terrestrial communities reflect the relative abundance of each community present in the study area (Table 2). Estimated impacts are derived based on the project length of 61 meters (200 ft.). The entire right-of-way (24.4 meters (80 feet)) was used for this calculation. Impacts as a result of the temporary detour are included. The entire right-of-way will probably not be impacted; therefore actual impacts to the communities may be considerably less. Table 2.

Moreover, a similar roadside shoulder community will be re-established after construction. Animals temporarily displaced by construction activities should repopulate areas suitable for the species following project completion. As a result, it is unlikely that 7 .r existing species will be displaced Fignificantly from the project ;3'ea following construction. However, to minimize the temporary effects of pr,?ject construction, all cleared areas along the roadways should be revegetated promptly after project completion to minimize erosion and the loss of wildlife habitat. Anticipated Impacts to Water Resources No waters classified as High Quality Waters (HQW) or Water Supplies (WS-I or WS-II) occur within 1.6 kilometers (1.0 mile) of project study area, however impacts will occur to Laurel Creek. One Outstanding Resource Waters (ORW) is located approximately 0.43 kilometers (0.27 miles) south of the project area. This watershed, which flows to Willis Lake [DWQ index no. 11-129-2-9, (8/3/92)], does not flow into Laurel Creek for approximately 4.5 kilometers (2.8 miles) downstream. Estimated Impacts to Laurel Creek are provided in Table 3. Impacts are calculated by using the width of the stream channel [6.1 meters (20 feet)] and the length of the culvert [17 meters (56 feet)] and the length of the temporary corrugated metal pipe [21meters (70 feet)]. Table 3. Estimated Impacts to Laurel Creek. New Culvert Tem Ali enf area m 103.7 1120.0 128 1400.0 Aquatic communities are sensitive to any changes in the environment. Any action that affects water quality can have an adverse impact on aquatic organisms. Although most of the disturbance caused by project construction will be temporary, some environmental impacts caused by the proposed project will be long term or irreversible. Installation or modification of in-stream structures, such as replacement or extension of culverts, can permanently affect many physical stream parameters. Project construction may result in the following impacts to surface waters: Increased silt loading and sedimentation from erosion of disturbed soils. Changes in light incidence, water clarity and water temperature due to increased sediment load and riparian vegetation removal. Alteration of stream discharge due to silt loading and changes in surface or ground water drainage patterns. Increased potential for release of toxic compounds such as fuel and oil from construction equipment and other vehicles. Precautions will be taken to minimize these and other impacts to water resources in the study area. NCDOT's Best Management Practices (BMP) for the Protection of Surface Waters will be strictly enforced throughout the construction stage of the project. JURISDICTIONAL TOPICS This section provides inventories and impact analyses pertinent to two substantial regulatory issues: Waters of the United States and rare and protected species. These issues retain particular importance because of federal and state mandates which regulate their protection. This section deals specifically with the impact analyses required to satisfy regulatory authority prior to project construction. Waters of the United States Surface waters and wetlands fall under the broad category of "Waters of the United States," as defined in Section 33 of the Code of Federal Register (CRF) Part 328.3. Any action that proposes to dredge or place fill material into surface waters or wetlands falls under the jurisdiction of the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean Water Act (33 U.S.C. 1344). Surface waters are waters used in interstate or foreign commerce, waters subject to the ebb and flow of tides, all interstate waters including interstate wetlands, and all other waters such as intrastate lakes, rivers, and streams. Surface waters include all standing or flowing waters which have commercial or recreational value to the public. Wetlands are identified based on the presence of hydric soils, hydrophytic vegetation, and saturated or flooded conditions during all or part of the growing season. Permits Impacts to jurisdictional surface waters are anticipated from the proposed project. As asesult, construction activities will require permits and certifications from various regulatory agencies in charge of protecting the water quality of public water resources. A Nationwide Permit 23 CFR 330 Appendix A (B) (23) is likely to be applicable for the crossing of Laurel Creek. This permit authorizes construction provided the following conditions are met: • the width of the fill is limited to the minimum necessary for the actual crossing; • the fill place in Waters of the United States is limited to a filled area of no more than 0.45 ha ( 1.0 ac); • no more than a total of 45.7 meters (150 linear feet) of the fill for the roadway can occur in special aquatic sites, including wetlands; • the crossing is culverted, bridged or otherwise designed to prevent the restriction of, and to withstand, expected high flows and tidal flows and movement of aquatic organisms, and; • the crossing, including all attendant features, both temporary and permanent, is part of a single and complete project for crossing of Waters of the United States. This project will also require a 401 Water Quality Certification from the DWQ prior to the issuance of the Nationwide Permit. Section 401 of the Clean Water Act requires that the state issue or deny water certification for any federally permitted or licensed activity that may result in a discharge to Waters of the United States. Section 401 Certification allows surface waters to be temporarily impacted for the duration of the construction or other land manipulation. The issuance of a 401 permit from the DWQ is a prerequisite to issuance of a Section 404 permit. The N. C. Wildlife Resources Commission (WRC) has designated Burke County as a Trout County but Laurel Creek is not Designated Public Mountain Trout Waters. Concurrence with the WRC will be required due to the crossing of Laurel Creek. Federally Protected Species Some populations of fauna and flora have been in, or are in, the process of decline either due to natural forces or their inability to coexist with human activities. Federal law (under the provisions of the Endangered Species Act of 1973, as amended) requires that any action, likely to adversely affect a species classified as federally protected, be subject to review by the Fish and Wildlife Service (FWS). 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. An endangered species is considered to be a species that is in danger of becoming extinct throughout all or a significant portion of its range. A threatened species is considered to be a species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. As of 14 May 1998, the U.S. Fish and Wildlife Service (FWS) lists six federally protected species for Burke County (Table 4). Descriptions and biological conclusions for each species are given below. Table 4. Federally Protected S ecies for Burke County Scientific,Name Common Name Status Falco ere inus anatum Peregrine falcon Endangered Geum radiatum spreading avens Endangered Hexas lis nani ora dwarf-flowered heartleaf Threatened Hudsonia montana mountain olden heather Threatened Isotria medeoloides small-whorled o onia Threatened Liatris helleri Heller's blazing star Threatened Endangered- a species is in danger of extinction throughout all or a significant portion of its range. Threatened- a species is likely to become extinct within the foreseeable future throughout all or a significant portion of its range. Falco peregrinus anatum (American peregrine falcon) Endangered Animal Family: Falconidae Date Listed: March 20, 1970 The anatum subspecies of the peregrine falcon is intermediate in coloring. The back is dark gray and the underside is off-white to tannish with dark barring. This subspecies appears slightly larger than the tundrius subspecies and has a wider black wedge forming the side of the helmet. Males of this species grow to an average length of 40 centimeters and females average 47.5 centimeters in length. The American peregrine falcon is found throughout the United States in areas with high cliffs and open land for foraging. Nesting for the falcons is generally on high cliff ledges but they may also nest in broken off treetops in the eastern deciduous forest and on skyscrapers and bridges in urban areas. Prey for the peregrine falcon consists of small mammals and birds. They occupy a range from 0.25 to 120 square miles depending on the availability of food. The hunting range usually extends 10 miles from the nest. Nesting occurs from mid-March to May. Suitable habitat consisting of high cliffs and open land for foraging is not present in the project area. No American peregrine falcons were observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of the North Carolina Natural Heritage Program 10 (NCNHP) database on July 31, 1998 indicated that there is no known occurrence of American peregrine falcon within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Geum radiatum (spreading avens) Endangered Plant Family: Rosaceae Federally Listed: April 5, 1990 Flowers Present: June - early July This species is found only in the North Carolina and Tennessee sections of the Southern Appalachian Mountains. Known populations in Burke County have been extirpated and populations in any other counties have shown- a serious decline. Stems of this perennial herb grow from horizontal rhizomes and obtain a height of 2-5 decimeters. The stems are topped with an indefinite cyme of bright yellow radially symmetrical flowers. Basal leaves are odd-pinnately compound, terminal leaflets are kidney shaped and much larger than the lateral leaflets, which are reduced or absent. Leaflets have lobed or uneven margins and are serrate, with long petioles. Stem leaves are smaller than the basal, rounded to obovate, with irregularly cut margins. Fruits are hemispheric aggregates of hairy achenes that are 7-9 mm in diameter. 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. The spreading avens is found in soils composed of sand, pebbles, humus, sandy loam, clay loam, and humus. Most populations are pioneers on rocky outcrops. Suitable habitat in the form of scarps, bluffs, cliffs and escarpments are not present in the project area. Spreading avens was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of the NCNHP database on July 31, 1998 indicated that there is no known occurrence of spreading avens within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Hexastylis naniflora (dwarf-flowered heartleaf) Threatened This plant has heart-shaped leaves, supported by long thin petioles that grow from a subsurface rhizome. It rarely exceeds 15 cm in height. The leaves are dark green in color, evergreen, and leathery. Flowers are small, inconspicuous, jugshaped, and dark brown in color. They are found near the base of the petioles. Fruits mature from mid-May to early July. Dwarf-flowered heartleaf populations are found along bluffs and their adjacent slopes, in boggy areas next to streams and creekheads, and along the slopes of nearby hillsides and ravines. It grows in acidic soils in regions with a cool moist climate. Regional vegetation is described as upper piedmont oak-pine forest and as part of the southeastern mixed forest. Suitable habitat in the form of bluffs and adjacent slopes is not present in the project area. Dwarf-flowered heartleaf was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. A review of the NCNHP database on July 31, 1998 indicated that there is one known occurrence of dwarf-flowered heartleaf within the project area. One population is recorded approximately 0.97 kilometers (0.6 miles) south of the project. However, this project will not affect this population. Biological Conclusion: No Effect Hudsonia Montana (mountain golden heather) Threatened Mountain golden heather is a low, needle-leaved shrub that is yellow-green in color. It usually grows in clumps 10 centimeters to 20 centimeters across and 15 centimeters high, it sometimes occurs in clumps that are a 30 centimeters or more across. The leaves from the previous year are retained and appear scale-like on the older branches. Leaves are from 3-7 millimeters long and appear awl-shaped and thread-like. It forms solitary, terminal, lanceolate flowers that are nearly three centimeters across. These yellow flowers have five blunt-tipped petals and 20 to 30 stamens. Fruit capsules have three projecting points at the tips, are rounded, and are found on 1.3-centimeter stalks. Hudsonia montana occurs in weathered rocky soils on mountaintops. It can be found on exposed quartzite ledges in an ecotone between bare rock and heath balds dominated by Leiophyllum which merge into pine forest. Plants do live in partially shaded areas, but do not appear to be as healthy as those found in open areas. Critical habitat has been designated in Burke County, North Carolina. The area is . bounded by the following: on the west by the 2200 foot contour; on the east by the Linville Gorge Wilderness Boundary north from the intersection of the 2200 foot contour and the Shortoff Mountain Trail to where it intersects the 3400 foot contour at "Chimneys"--then follow the 3400 foot contour north until it reintersects with the Wilderness Boundary--then follow the Wilderness Boundary again northward until it intersect the 3200 foot contour extending west from its intersection with the Wilderness Boundary until it begins to turn south--at this point the Boundary extends due east until it intersects the 2200 foot contour. Suitable habitat in the form of ecotones between bare rock and heath balds is not present in the project area. Mountain golden heather was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of NCNHP database on July 31, 1998 indicated that there is no known occurrence of mountain golden heather within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Isotria medeoloides (small-whorled pogonia) Threatened The small-whorled pogonia was known historically from Maine to Georgia, with the exception of Delaware, along the eastern seaboard and in Michigan, Illinois, and Missouri. In North Carolina it is found in the Nantahala National Forest, Macon County and near the town of Flat Rock, Henderson County. 12 This perennial orchid has long pubescent roots and a hollow stem 9.5 centimeters to 25 centimeters tall. Stems terminate in a whorl of five or six light green, elliptical leaves that are somewhat pointed. Leaves measure approximately 8 x 4 centimeters. One or two light green flowers are produced at the end of the stem. Flowers have short sepals that are only 2.5 centimeters long. The small-whorled pogonia grows in "second growth deciduous" or deciduous-coniferous forests, with an open canopy, open shrub layer, and sparse herb layer. It prefers acidic soils. Flowering is inhibited in areas where there is relatively high shrub coverage or high sapling density. Suitable habitat in the form of second growth deciduous is not present in the project area. Small-whorled pogonia was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of NCNHP database on July 31, 1998 indicated that there is no known occurrence of small-whorled pogonia within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Liatris helleri (Heller's blazing star) Threatened 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. Heller's 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 accuminate and diminish in size and breadth upward on the stem. Stems are 4 dm tall and are topped with a raceme of small (7-20 cm) 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. Suitable habitat in the form of high elevation ledges of rock outcrops is not present in the project area. Heller's blazing star was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review the NCNHP database on July 31, 1998 indicated that there is no known occurrence of Heller's blazing star within the project area. Therefore, this project will not affect this species.

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

Federal Aid Project No. MABRZ-1984(2), State Project No. 8.2851901, TIP Project No. B-3312. Please find enclosed three copies of the project planning report for the above referenced project. This project involves the proposed replacement of Bridge No. 347 on SR 1984 over Laurel Creek in Burke County. The existing bridge will be replaced with a double-barrel box culvert, with each barrel 12 feet x 9 feet, on existing alignment. Project length is 286 feet, and the proposed roadway will have a 20-foot paved surface and 4-foot grass shoulders. The existing bridge is composed entirely of timber and steel and will result in no temporary fill due to bridge demolition debris. NCDOT's Best Management Practices for Bridge Demolition and Removal will be followed during demolition of the existing bridge. Traffic will be maintained on a temporary on-site detour during construction. This detour will be located approximately 50 feet west of the existing structure, and will utilize two 96-inch corrugated metal pipes to maintain the flow of Laurel Creek. No wetlands are contained within the proposed project limits; however, temporary and permanent impacts to jurisdictional surface waters are anticipated. Temporary impacts to Laurel Creek from the detour will be 75 linear feet and permanent impacts from the proposed culvert will be 62 linear feet. In addition, there will be a 35-foot channel relocation at the culvert outlet. An intermittent stream channel was identified after the completion of the planning document, and will have temporary and permanent impacts. This intermittent stream flows into Laurel Creek just west of the existing bridge, and parallels SR 1984 (see attached plan view). Temporary impacts due to detour fill will be 65 linear feet and permanent impacts due to proposed piping will be 55 linear feet. This project is being processed by the Federal Highway Administration as a "Categorical Exclusion" in accordance with 23 CFR 771.115(b). Therefore, we do not anticipate requesting an individual permit, but propose to proceed under Nationwide Permit 23 in accordance with the Federal Register of December 13, 1996, Part VII, Volume 61, Number 241. We anticipate a 401 General Certification will apply to this project, and are providing one copy of the CE document to the North Carolina Department of Environment and Natural Resources, Division of Water Quality, for their review. This project will take place in a mountain trout county. Thus we anticipate that comments from the North Carolina Wildlife Resources Commission (NCWRC) will be required. By copy of this letter and attachment, NCDOT hereby requests NCWRC review. We request that the NCWRC forward their comments to the US Army Corps of Engineers.

It is programmed in the Draft 2000-2006 Transportation Improvement Program (TIP) as a bridge replacement project. This project is part of the Federal Highway Bridge Replacement and Rehabilitation Program (HBRRP) and has been classified as a "Categorical Exclusion". No substantial environmental impacts are expected. I. SUMMARY OF RECOMMENDATIONS Bridge No. 347 will be replaced with a two-barrel box culvert on the existing alignment (see Figure 2). Each barrel of the box culvert will be 2.7 x 2.7 meters (9 x 9 feet). Traffic will be maintained on a temporary alignment 15 meters (50 feet) west of the existing structure. The project length is 61 meters (200 feet) (see Figure 2). The pavement width will be 6.0 meters (20 feet) including two 3.0-meter (10-foot) lanes. The grass shoulders will be 1.2 meters (4 feet) wide. Based on preliminary design, the design speed should be approximately 50 km/h (30 mph). The pavement width on the temporary alignment will be 5.4 meters (18 feet). The width of the grass shoulders will be 1.2 meters (4.0 feet). Two 1800-millimeter (72- inch) corrugated metal pipes will maintain the flow in Laurel Creek during construction. The design speed for the detour alignment will be 30 km/h (20 mph). The estimated cost of the project is $420,000 including $375,000 in construction costs and $45,000 in right of way costs. The estimated cost shown in the Draft 2000- 2006 TIP is $355,000; including $328,000 in construction costs, and $27,000 in right of way costs. II. SUMMARY OF ENVIRONMENTAL COMMITMENTS All standard procedures and measures will be implemented to avoid or minimize environmental impacts. All practical Best Management Practices (BMP's) will be included and properly maintained during project construction. In accordance with the provisions of Section 404 of the Clean Water Act (33 U.S.C. 1344), a permit will be required from the Corps of Engineers for the discharge of dredged or fill material into "Waters of the United States." North Carolina Division of Water Quality (DEM) Section 401 Water Quality General Certification will be obtained prior to issue of the Army Corps of Engineers Nationwide Permit # 23. Foundation investigations will be required on this project. The investigation will include test borings in soil and/or rock for in-site testing as well as obtaining samples for laboratory testing. This may require test borings in streams and/or wetlands. NCWRC has commented that Laurel Creek is not Designated Public Mountain Trout Waters. NCWRC has no special concerns regarding this project. III. ANTICIPATED DESIGN EXCEPTIONS NCDOT anticipates that a design exception may be necessary due to horizontal and vertical alignment. The topography of the project makes it impossible to improve horizontal or vertical alignment without significant blasting into the mountain on the south approach to the bridge. IV. EXISTING CONDITIONS SR 1984 is classified as a Rural Local route in the Statewide Functional Classification System. Traffic volume is 300 vehicles per day (VPD) and projected at 600 VPD for the year 2020. There is no posted speed limit on SR 1984 in the vicinity of the bridge. The land along SR 1984 is a mixture of undeveloped land with pockets of residential development. The existing bridge was completed in 1963. It is 11 meters (36 feet) long. The deck is 6.1 meters (20 feet) wide. There is approximately 3.4 meters (11 feet) vertical clearance between the bridge deck and streambed. There are two lanes of traffic on the bridge. According to Bridge Maintenance Unit records, the sufficiency rating of the bridge is 14.8 out of a possible 100. Presently the bridge is posted with weight restrictions of 12 tons for single vehicles and 16 tons for truck-tractor semi-trailers. The vertical alignment near the bridge is fair. Immediately south of the bridge the road begins to climb quickly. The horizontal alignment as shown in Figure 2 is fair. Shoulders on both approaches of the bridge are approximately 1.0 meter (3 feet) wide. The Traffic Engineering Branch indicates that two accidents have been reported in the period from May 1994 to April 1997 in the vicinity of the project. The accidents were not the result of the bridge or the alignment. There are 8 daily school bus crossings over the studied bridge. The Transportation Director noted that the crossing was the only access to SR 1984 and assumed that some provision would be made to leave the road open. There are aerial power and telephone utilities in the project vicinity but it is uncertain as to what might be affected by the project. Even so, utility impacts would be considered low. 2 V. PROPOSED ALTERNATIVES One build alternative was fully evaluated during the planning process. Bridge No. 347 will be replaced on the existing location. Traffic will be maintained on a temporary alignment during construction. Detouring traffic is not possible because SR 1984 is a dead end road. Realigning SR 1984 along the proposed detour route and maintaining traffic on the existing structure during construction would have required a curved approach to the intersection or a skewed intersection. This would potentially create a hazard not currently experienced by travelers trying to turn onto NC 18. Because of topography and buildings, all other considerations would have been far more costly and environmentally damaging than the option chosen. "Do-nothing" is not practical, requiring the eventual closing of the road as the existing bridge completely deteriorates. Rehabilitation of the existing deteriorating bridge is neither practical nor economical. VI.

RECOMMENDED IMPROVEMENTS Bridge No. 347 will be replaced as with a two-barrel box culvert on the existing alignment (see Figure 2). Each barrel of the box culvert will be 2.7 x 2.7 meters (9 x 9 feet). Traffic will be maintained on a temporary alignment 15 meters (50 feet) west of the existing structure. The project length is 61 meters (200 feet) (see Figure 2). The pavement width will be 6.0 meters (20 feet) including two 3.0-meter (10-foot) lanes. The grass shoulders will be 1.2 meters (4 feet) wide. Based on preliminary design, the design speed should be approximately 50 km/h (30 mph). The pavement width on the temporary alignment will be 5.4 meters (18 feet). The width of the grass shoulders will be 1.2 meters (4.0 feet). Two 1800-millimeter (72- inch) corrugated metal pipes will maintain the flow in Laurel Creek. The design speed for the detour alignment will be 30 km/h (20 mph). Because all other possible alternates would have been far more expensive and more environmentally damaging, the recommended improvement is the only reasonable and feasible choice. VIII. ENVIRONMENTAL EFFECTS A. GENERAL This project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. This project is considered to be a "Categorical Exclusion" due to its limited scope and insignificant environmental consequences. This bridge replacement will not have a substantial adverse effect on the quality of the human or natural environment by implementing the environmental commitments listed in Section II of this document in addition to use of current NCDOT standards and specifications. The project is not in conflict with any plan, existing land use, or zoning regulation. No change in land use is expected to result from construction of this project. There are no hazardous waste impacts. No adverse effect on families or communities is anticipated. Right-of-way acquisition will be limited. No adverse effect on public facilities or services is expected. The project is not expected to adversely affect social, economic, or religious opportunities in the area. There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of national, state, or local significance in the vicinity of the project. The proposed bridge replacement project will not raise the existing flood levels or have any significant adverse effect on the existing floodplain. Utility impacts are considered to be low for the proposed project. B. AIR AND NOISE This project is an air quality "neutral" project, so it is not required to be included in the regional emissions analysis and a project level CO analysis is not required. 4 The project is located in Burke 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 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 will not substantially increase traffic volumes. Therefore, it will not have substantial impact on noise levels. Temporary noise increases may occur during construction. C. LAND USE & FARMLAND EFFECTS In compliance with the Farmland Protection Policy Act (FPPA) of 1981, the project was evaluated for impacts to prime or important farmland soils. The project will have no impacts to prime or important farmland soils. D. HISTORICAL EFFECTS & ARCHAEOLOGICAL EFFECTS Upon review of area photographs, aerial photographs, and cultural resources databases, the State Historic Preservation Office (SHPO) has recommended that neither an architectural or archaeological survey is required. E. NATURAL RESOURCES Physical Resources Water and soil resources, which occur in the study area, are discussed below. The availability of water and soils directly influence composition and distribution of flora and fauna in any biotic community. Water Resources Field surveys revealed that one body of surface water is located within the project area. The Division of Water Quality (DWQ) has assigned index numbers for streams and tributaries in North Carolina. One perennial stream in the Catawba River Basin, Laurel Creek [DWQ Index No. 11-129-1-13, (3/1/62)] is crossed by SR 1984. This stream carries a Best Usage Classification of Class C. Class C refers to waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The stream flow of Laurel Creek was moderate at the time of field visit. The stream was approximately 3.6 meters (12 feet) in width with an average channel width of 6.1 meters (20 feet). The stream was approximately 0.46 meters (1.5 feet) deep. The substrate consisted of sand, silt, and cobble. Point sources refer to discharges that enter surface water through a pipe, ditch, or other defined points of discharge. The term most commonly refers to discharges associated with wastewater treatment plants. Point source dischargers located throughout North Carolina are permitted through the National Pollutant Discharge Elimination System (NPDES) program. Any discharger is required to register for a permit. There is one NPDES site located within 1.6 kilometers (1.0 mile) upstream of the project study area. Permit No. NCG550655 was issued on 2/10/94 to the Laurel Creek Mobile Home Park. This permittee discharges into Laurel Creek approximately 1823 meters (5981 feet) upstream of the project area. Non-point source refers to runoff that enters surface waters through stormwater flow or no defined point of discharge. There are many types of land use activities that can serve as sources of nonpoint source pollution including land development, construction, crop production, animal feeding lots, failing septic systems, landfills, roads, and parking lots. Sediment and nutrients are major pollution-causing substances associated with nonpoint source pollution. Others include fecal coliform bacteria, heavy metals, oil and grease, and any other substance that may be washed off the ground or removed from the atmosphere and carried into surface waters. The Benthic Macroinvertebrate Ambient Network (BMAN) is managed by DWQ and is part of an ongoing ambient water quality monitoring program which addresses long term trends in water quality. The program assesses water quality by sampling for selected benthic macroinvertebrate organisms at fixed monitoring sites. Some macroinvertebrates are sensitive to very subtle changes in water quality; thus, the species richness and overall biomass of these organisms are reflections of water quality. There are no BMAN sites within the project vicinity. Soils and Topography The Cliffside series is the dominant soil series occurring at the project site (Table 1). The Cliffside series consists of soils on upland ridges and side slopes. The Udorthents series consists of areas where the natural soils have been altered by digging, grading, or filling, to the extent that individual soil types can no longer be recognized. Table 1. Soils occurrin in the roiect area 'Map Unit Symbol Mapping Unit Permeability - Slope (%) Shrink- well Hydric Class Ud Udorthents, loam n/a 0-2 n/a Non H dric 66C Cliffside-Woolwine moderate 8-15 low Non H dric 66D Cliffside-Fairview moderate 15-25 low Non H dric The topography within the project area ranges from approximately 323.1- 335.3 meters (1060-1100 feet) above mean sea level. BIOTIC RESOURCES Terrestrial Communities Three terrestrial communities, maintained roadside, riparian fringe, and residential/business, exist within the project area, and will be impacted by the subject project. The maintained roadside community consists of the highly maintained shoulders and some less intensively managed areas that grade into the surrounding natural communities. Significant soil disturbance and compaction, along with frequent mowing or herbicide application, keep this community in an early successional state. Dominant plants in the heavily maintained portions of the roadside community include fescue and plantain. In the areas that receive lower levels of maintenance, more diverse communities can develop. Japanese honeysuckle, dog fennel, bush clover, grape, Southern lady fern, ragweed, pokeweed, poison oak, and smooth sumac populate this community.. .4 N A residential/business community exists in the location of the proposed temporary bridge and road. This corgiunity includes the following speCtes: fescue, winged elm, mimosa, Canada hemlock), white pine, ragweed, Southern ;ady fern, and smooth sumac. The riparian edge community included herb and vine species such as poison ivy, jewelweed, elderberry, Virginia creeper, rosebay and Christmas fern. Trees found in this community are white oak, red maple, tulip poplar, black gum, black cherry, dogwood, sycamore, sweet gum, and tree-of-heaven. Wildlife found in these communities is limited and consists primarily of wide-ranging, adaptable species, which are well suited to coexistence with human development. Mammals common to disturbed edge areas, such as eastern cottontail rabbit, raccoon, white-tailed deer, and gray squirrel may inhabit forested fringes. The most common reptiles found in such habitats are eastern box turtle and predators such as black racer, and eastern garter snake. Birds likely to frequent such habitats include common crow, American robin, mourning dove, and European starling. Freshwater fishes likely to be found in creeks such as Laurel Creek may include creek chub, redbreast sunfish, white shiner, and rosyside dace. Summary of Anticipated Impacts Construction of the proposed project will have various impacts on the biotic resources described. This section quantifies and qualifies potential impacts to the natural communities within the project area in terms of the area impacted and the organisms affected. Temporary versus permanent impacts are considered as well, along with recommendations to minimize or eliminate impacts. ?)Anticipated Impacts to Terrestrial Communities Impacts to terrestrial communities will result from project construction due to the clearing and paving of portions of the project area, and thus the loss of community area. Calculated quantitative impacts to terrestrial communities reflect the relative abundance of each community present in the study area (Table 2). Estimated impacts are derived based on the project length of 61 meters (200 ft.). The entire right-of-way (24.4 meters (80 feet)) was used for this calculation. Impacts as a result of the temporary detour are included. The entire right-of-way will probably not be impacted; therefore actual impacts to the communities may be considerably less. Table 2.

Moreover, a similar roadside shoulder community will be re-established after construction. Animals temporarily displaced by construction activities should repopulate areas suitable for the species following project completion. As a result, it is unlikely that existing species will be displaced Fignificantly from the project ;rea following construction. However, to minimize the temporary effects of project construction, all cleared areas along the roadwgs should be revegetated promptly after project completion to minimize erosion and the loss of wildlife habitat. Anticipated Impacts to Water Resources No waters classified as High Quality Waters (HQW) or Water Supplies (WS-I or WS-II) occur within 1.6 kilometers (1.0 mile) of project study area, however impacts will occur to Laurel Creek. One Outstanding Resource Waters (ORW) is located approximately 0.43 kilometers (0.27 miles) south of the project area. This watershed, which flows to Willis Lake [DWQ index no. 11-129-2-9, (8/3/92)], does not flow into Laurel Creek for approximately 4.5 kilometers (2.8 miles) downstream. Estimated Impacts to Laurel Creek are provided in Table 3. Impacts are calculated by using the width of the stream channel [6.1 meters (20 feet)] and the length of the culvert [17 meters (56 feet)] and the length of the temporary corrugated metal pipe [21meters (70 feet)]. Table 3. Estimated Impacts to Laurel Creek. New Culvert Tem Alignment ?EEJ area m 103.7 1120.0 128 1400.0 Aquatic communities are sensitive to any changes in the environment. Any action that affects water quality can have an adverse impact on aquatic organisms. Although most of the disturbance caused by project construction will be temporary, some environmental impacts caused by the proposed project will be long term or irreversible. Installation or modification of in-stream structures, such as replacement or extension of culverts, can permanently affect many physical stream parameters. Project construction may result in the following impacts to surface waters: Increased silt loading and sedimentation from erosion of disturbed soils. Changes in light incidence, water clarity and water temperature due to increased sediment load and riparian vegetation removal. Alteration of stream discharge due to silt loading and changes in surface or ground water drainage patterns. Increased potential for release of toxic compounds such as fuel and oil from construction equipment and other vehicles. Precautions will be taken to minimize these and other impacts to water resources in the study area. NCDOT's Best Management Practices (BMP) for the Protection of Surface Waters will be strictly enforced throughout the construction stage of the project. JURISDICTIONAL TOPICS This section provides inventories and impact analyses pertinent to two substantial regulatory issues: Waters of the United States and rare and protected species. These issues retain particular importance because of federal and state mandates which regulate their protection. This section deals specifically with the impact analyses required to satisfy regulatory authority prior to project construction. Waters of the United States Surface waters and wetlands fall under the broad category of "Waters of the United States," as defined in Section 33 of the Code of Federal Register (CRF) Part 328.3. Any action that proposes to dredge or place fill material into surface waters or wetlands falls under the jurisdiction of the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean Water Act (33 U.S.C. 1344). Surface waters are waters used in interstate or foreign commerce, waters subject to the ebb and flow of tides, all interstate waters including interstate wetlands, and all other waters such as intrastate lakes, rivers, and streams. Surface waters include all standing or flowing waters which have commercial or recreational value to the public. Wetlands are identified based on the presence of hydric soils, hydrophytic vegetation, and saturated or flooded conditions during all or part of the growing season. Permits Impacts to jurisdictional surface waters are anticipated from the proposed project. As a result, construction activities will require permits and certifications from various regulatory agencies in charge of protecting the water quality of public water resources. A Nationwide Permit 23 CFR 330 Appendix A (B) (23) is likely to be applicable. for the crossing of Laurel Creek. This permit authorizes construction provided the following conditions are met: • the width of the fill is limited to the minimum necessary for the actual crossing; • the fill place in Waters of the United States is limited to a filled area of no more than 0.45 ha ( 1.0 ac); • no more than a total of 45.7 meters (150 linear feet) of the fill for the roadway can occur in special aquatic sites, including wetlands; • the crossing is culverted, bridged or otherwise designed to prevent the restriction of, and to withstand, expected high flows and tidal flows and movement of aquatic organisms, and; • the crossing, including all attendant features, both temporary and permanent, is part of a single and complete project for crossing of Waters of the United States. This project will also require a 401 Water Quality Certification from the DWQ prior to the issuance of the Nationwide Permit. Section 401 of the Clean Water Act requires that the state issue or deny water certification for any federally permitted or licensed activity that may result in a discharge to Waters of the United States. Section 401 Certification allows surface waters to be temporarily impacted for the duration of the construction or other land manipulation. The issuance of a 401 permit from the DWQ is a prerequisite to issuance of a Section 404 permit. The N. C. Wildlife Resources Commission (WRC) has designated Burke County as a Trout County but Laurel Creek is not Designated Public Mountain Trout Waters. Concurrence with the WRC will be required due to the crossing of Laurel Creek. Federally Protected Species Some populations of fauna and flora have been in, or are in, the process of decline either due to natural forces or their inability to coexist with human activities. Federal law (under the provisions of the Endangered Species Act of 1973, as amended) requires that any action, likely to adversely affect a species classified as federally protected, be subject to review by the Fish and Wildlife Service (FWS). 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. An endangered species is considered to be a species that is in danger of becoming extinct throughout all or a significant portion of its range. A threatened species is considered to be a species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. As of 14 May 1998, the U.S. Fish and Wildlife Service (FWS) lists six federally protected species for Burke County (Table 4). Descriptions and biological conclusions for each species are given below. Table 4. Federally Protected S ecies for Burke County :Scientific Name ` CommonName Status Falco ere inus anatum Peregrine falcon Endangered Geum radiatum spreading avens Endangered Hexas lis nani ora dwarf-flowered heartleaf Threatened Hudsonia montana mountain olden heather Threatened Isotria medeoloides small-whorled o onia Threatened Liatris helleri Heller's blazing star Threatened Endangered- a species is in danger of extinction throughout all or a significant portion of its range. Threatened- a species is likely to become extinct within the foreseeable future throughout all or a significant portion of its range. Falco peregrinus anatum (American peregrine falcon) Endangered Animal Family: Falconidae Date Listed: March 20, 1970 The anatum subspecies of the peregrine falcon is intermediate in coloring. The back is dark gray and the underside is off-white to tannish with dark barring. This subspecies appears slightly larger than the tundrius subspecies and has a wider black wedge forming the side of the helmet. Males of this species grow to an average length of 40 centimeters and females average 47.5 centimeters in length. The American peregrine falcon is found throughout the United States in areas with high cliffs and open land for foraging. Nesting for the falcons is generally on high cliff ledges but they may also nest in broken off treetops in the eastern deciduous forest and on skyscrapers and bridges in urban areas. Prey for the peregrine falcon consists of small mammals and birds. They occupy a range from 0.25 to 120 square miles depending on the availability of food. The hunting range usually extends 10 miles from the nest. Nesting occurs from mid-March to May. Suitable habitat consisting of high cliffs and open land for foraging is not present in the project area. No American peregrine falcons were observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of the North Carolina Natural Heritage Program 10 (NCNHP) database on July 31, 1998 indicated that there is no known occurrence of American peregrine falcon within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Geum radiatum (spreading avens) Endangered Plant Family: Rosaceae Federally Listed: April 5, 1990 Flowers Present: June - early July This species is found only in the North Carolina and Tennessee sections of the Southern Appalachian Mountains. Known populations in Burke County have been extirpated and populations in any other counties have shown- a serious decline. Stems of this perennial herb grow from horizontal rhizomes and obtain a height of 2-5 decimeters. The stems are topped with an indefinite cyme of bright yellow radially symmetrical flowers. Basal leaves are odd-pinnately compound, terminal leaflets are kidney shaped and much larger than the lateral leaflets, which are reduced or absent. Leaflets have lobed or uneven margins and are serrate, with long petioles. Stem leaves are smaller than the basal, rounded to obovate, with irregularly cut margins. Fruits are hemispheric aggregates of hairy achenes that are 7-9 mm in diameter. 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. The spreading avens is found in soils composed of sand, pebbles, humus, sandy loam, clay loam, and humus. Most populations are pioneers on rocky outcrops. Suitable habitat in the form of scarps, bluffs, cliffs and escarpments are not present in the project area. Spreading avens was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of the NCNHP database on July 31, 1998 indicated that there is no known occurrence of spreading avens within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Hexastylis naniflora (dwarf-flowered heartleaf) Threatened This plant has heart-shaped leaves, supported by long thin petioles that grow from a subsurface rhizome. It rarely exceeds 15 cm in height. The leaves are dark green in color, evergreen, and leathery. Flowers are small, inconspicuous, jugshaped, and dark brown in color. They are found near the base of the petioles. Fruits mature from mid-May to early July. Dwarf-flowered heartleaf populations are found along bluffs and their adjacent slopes, in boggy areas next to streams and creekheads, and along the slopes of nearby hillsides and ravines. It grows in acidic soils in regions with a cool moist climate. Regional vegetation is described as upper piedmont oak-pine forest and as part of the southeastern mixed forest. Suitable habitat in the form of bluffs and adjacent slopes is not present in the project area. Dwarf-flowered heartleaf was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. A review of the NCNHP database on July 31, 1998 indicated that there is one known occurrence of dwarf-flowered heartleaf within the project area. One population is recorded approximately 0.97 kilometers (0.6 miles) south of the project. However, this project will not affect this population. Biological Conclusion: No Effect Hudsonia Montana (mountain golden heather) Threatened Mountain golden heather is a low, needle-leaved shrub that is yellow-green in color. It usually grows in clumps 10 centimeters to 20 centimeters across and 15 centimeters high, it sometimes occurs in clumps that are a 30 centimeters or more across. The leaves from the previous year are retained and appear scale-like on the older branches. Leaves are from 3-7 millimeters long and appear awl-shaped and thread-like. It forms solitary, terminal, lanceolate flowers that are nearly three centimeters across. These yellow flowers have five blunt-tipped petals and 20 to 30 stamens. Fruit capsules have three projecting points at the tips, are rounded, and are found on 1.3-centimeter stalks. Hudsonia montana occurs in weathered rocky soils on mountaintops. It can be found on exposed quartzite ledges in an ecotone between bare rock and heath balds dominated by Leiophyllum which merge into pine forest. Plants do live in partially shaded areas, but do not appear to be as healthy as those found in open areas. Critical habitat has been designated in Burke County, North Carolina. The area is . bounded by the following: on the west by the 2200 foot contour; on the east by the Linville Gorge Wilderness Boundary north from the intersection of the 2200 foot contour and the Shortoff Mountain Trail to where it intersects the 3400 foot contour at "Chimneys"--then follow the 3400 foot contour north until it reintersects with the Wilderness Boundary--then follow the Wilderness Boundary again northward until it intersect the 3200 foot contour extending west from its intersection with the Wilderness Boundary until it begins to turn south--at this point the Boundary extends due east until it intersects the 2200 foot contour. Suitable habitat in the form of ecotones between bare rock and heath balds is not present in the project area. Mountain golden heather was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of NCNHP database on July 31, 1998 indicated that there is no known occurrence of mountain golden heather within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Isotria medeoloides (small-whorled pogonia) Threatened The small-whorled pogonia was known historically from Maine to Georgia, with the exception of Delaware, along the eastern seaboard and in Michigan, Illinois, and Missouri. In North Carolina it is found in the Nantahala National Forest, Macon County and near the town of Flat Rock, Henderson County. 12 This perennial orchid has long pubescent roots and a hollow stem 9.5 centimeters to 25 centimeters tall. Stems terminate in a whorl of five or six light green, elliptical leaves that are somewhat pointed. Leaves measure approximately 8 x 4 centimeters. One or two light green flowers are produced at the end of the stem. Flowers have short sepals that are only 2.5 centimeters long. The small-whorled pogonia grows in "second growth deciduous" or deciduous-coniferous forests, with an open canopy, open shrub layer, and sparse herb layer. It prefers acidic soils. Flowering is inhibited in areas where there is relatively high shrub coverage or high sapling density. Suitable habitat in the form of second growth deciduous is not present in the project area. Small-whorled pogonia was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review of NCNHP database on July 31, 1998 indicated that there is no known occurrence of small-whorled pogonia within the project area. Therefore, this project will not affect this species. Biological Conclusion: No Effect Liatris helleri (Heller's blazing star) Threatened 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. Heller's 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 accuminate and diminish in size and breadth upward on the stem. Stems are 4 dm tall and are topped with a raceme of small (7-20 cm) 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. Suitable habitat in the form of high elevation ledges of rock outcrops is not present in the project area. Heller's blazing star was not observed during a survey conducted on July 27, 1998 by NCDOT biologists Chris Rivenbark, Logan Williams, and Josh Witherspoon. In addition, a review the NCNHP database on July 31, 1998 indicated that there is no known occurrence of Heller's blazing star within the project area. Therefore, this project will not affect this species.

We reported our available information on historic architectural and archaeological surveys and resources along with our recommendations. NCDCT provided project area photographs and aerial photographs at the meeting. Based upon our review of the photographs and the information discussed at the meeting, we offer our preliminary comments regarding this project. In terms of historic architectural resources, we are aware of no historic structures located within the area of potential effect. We recommend that no historic architectural survey be conducted for this project. There are no known archaeological sites within the proposed project area. Based on our present knowledge of the area, it is unlikely that any archaeological resources which may be eligible for inclusion in the National Register of Historic Places will be affected by the project construction. We, therefore, recommend that no archaeological investigation be conducted in connection with this project. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which indicates how NCDOT addressed our comments. The above comments are made pursuant to Section 106 of the National Historic Preservation Act of 1966 and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codified at 36 CFR Part 800. 109 Fast Joncs Street - Raleigh, North Carolina 27601-2807 n L Fes- - ^P SURVEY/PLANNING-NCSHPO TEL:919-715-4801 Jun 17'98 8:41 No.001 P.03 Nicholas L.

Fullwood, Executive Director June 23, 2000 Mr. Steve Lund, NCDOT Coordinator U. S. Army Corps of Engineers t, Regulatory Branch 151 Patton Avenue, Room 143 Asheville, North Carolina 28801-5006 SUBJECT: NCDOT Nationwide 404 Permit Application Bridge replacement on SR 1984 - Bridge No. 347 over Laurel Creek Burke County, North Carolina Dear Mr. Lund: Mr. William D. Gilmore, P.E. of the North Carolina Department of Transportation (NCDOT) is requesting a letter of concurrence from the North Carolina Wildlife Resources Commission (NCWRC) to obtain a 404 permit from the U.S. Army Corps of Engineers. I have reviewed information provided by the applicant, and I am familiar with habitat values of the project area. These comments are provided in accordance with provisions of the Clean Water Act of 1.977 (33 U.S.C. 466 et seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). The applicant proposes to replace the existing bridge on SR 1984 over Laurel Creek with double-barrel box culvert. Laurel Creek is not a designated trout stream by NCWRC, and trout are not known to occur in the project area (MEMORANDUM: Joe H. Mickey, Jr., May 8, 1998). Although, the NCWRC is concerned about potential project impacts to other aquatic resources in this drainage, we do not object to the issuance of a 404 permit provided the following conditions are placed on the subject permit: 1. Adequate sedimentation and erosion control treasures must be implemented prior to any ground- disturbing activities to minimize impacts to downstream aquatic resources. Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15 days of ground disturbing activities to provide long-term erosion control. 2. The culverts should be placed with the floor of the barrel approximately one foot below the level of the stream bottom to allow natural stream bottom materials to become established in the culvert and to provide fish passage during periods of low flow. This may require increasing the size of the culvert to meet flow conveyance requirements. 3. Under no circumstances should rock, sand, or other materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate vicinity of the culverts. Instream dredging has catastrophic effects on aquatic life, and disturbance of the natural form of the stream channel will likely cause downstream erosion problems, possibly affecting adjacent landowners. Bridge Replacement Permit Page 2 June 23, 2000 4. If concrete is used during culvert installation (headwalls), a dry work area must be maintained to prevent direct contact between curing concrete and stream water. Uncured concrete affects water quality and is highly toxic to fish and other aquatic organisms. 5. If possible, stormwater should be directed to buffer areas or retention basins and should not be routed directly into streams. 6. Rock check dams at culvert outlets should be removed once the project is stabilized. This will allow upstream migration of fish during periods of low flow. 7. Riprap placed for bank stabilization should be limited to the stream bank below the high water mark, and vegetation should be used for stabilization above the high water elevation. 8. All mechanized equipment operated near surface waters should be regularly inspected and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. Thank you for the opportunity to review and comment on this project. Pending availability of field staff, the NCWRC may inspect the work site during or after construction. If there are any questions regarding these . comments, please contact me at (828) 452-0422.
