The NCDOT proposes to replace the 53-foot Bridge No. 84 on SR 2579 over Jones Creek with a new 95-foot single-span reinforced concrete box-beam bridge in the same location. In addition, the NCDOT plans to replace the 60-inch corrugated metal cross pipe which carries an unnamed tributary (UT) to Jones Creek under SR 2579 and is approximately 400 feet fast of the bridge. This cross pipe will be replaced with a 96-inch corrugated steel pipe. There will be 0.008 acre of temporary fill and 30 ft of temporary stream impact due to the stream diversion and replacement of the pipe. The bridge replacement will have no impacts to jurisdictional waters. Traffic will be detoured off-site during construction at both locations. IMPACTS TO WATERS OF THE UNITED STATES General Description: The project is located in the Roanoke River Basin (ROA03 Subbasin) with a Hydrological Unit Code of 03010104. The proposed bridge (Site 1) and pipe (Site 2) replacements are located over Jones Creek and UT Jones Creek, respectively. Jones Creek flows from the southwest and meets with UT Jones Creek on the northeast side of the bridge. MAILING ADDRESS: TELEPHONE: 919-715-1500 LOCATION: NC DEPARTMENT OF TRANSPORTATION FAX: 919-715-1501 2728 CAPITAL BLVD PROJECT DEVELOPMENT AND ENVIRONMENTAL ANALYSIS PLB SUITE 168 1598 MAIL SERVICE CENTER WEBSITE. WWW.NCDOT.ORG RALEIGH NC 27604 RALEIGH NC 27699-1598 . I Both creeks have been assigned a Division of Water Quality best usage classification of "C". Class "C" refers to waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation and agriculture. There are no wetlands in the project area. Temporary Impacts: Temporary impacts for this project are associated with the pipe replacement. The pipe replacement at Site 2 will be the same length as the existing pipe culvert. The new pipe will be buried one foot below the streambed. Approximately 15 feet upstream and 15 feet downstream of the structure there will be temporary impacts from stream diversion while installing the culvert. There will also be 0.008 acre of temporary fill in the surface water. Traffic will be detoured off-site during pipe installation. NCDOT's Best Management Practices, dated August 2003, for pipe and flow diversion will be followed during replacement of the pipe on UT Jones Creek. • Schedule: All steps will be taken to minimize stream impacts for UT Jones Creek. NCDOT will request the contractor to complete construction in a timely manner. The project schedule calls for a Let date of October 19, 2004 with a date of availability of November 17, 2004. • Restoration Plan: The material used for fill to control erosion within the banks of UT Jones Creek will be removed after the purpose has been served. The contractor will be required to submit a reclamation plan for removal of and disposal of all material off-site. Utility Impacts: There will be no sewer, water, electric or other utility impacts due to this bridge replacement project. Bridge Demolition: Bridge No. 84 has three spans totaling 53 feet in length. The entire bridge is composed of timber. Therefore, bridge No. 84 will be removed without dropping any of its components in the surface waters. NCDOT's Best Management Practices for Bridge Demolition and Removal will be followed. FEDERALLY PROTECTED SPECIES Plants and animals with federal classifications of Endangered, Threatened, Proposed Endangered and Proposed Threatened are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. As of January 29, 2003 the US Fish and Wildlife Service (USFWS) lists two federally protected species for . Rockingham County: smooth coneflower and the James spinymussel. No species have been added to or deleted from this list since the completion of the referenced document. Field surveys were conducted in 2001 and 2003 for mussels and 2002 for the plants. A biological conclusion of "May affect, Not Likely to Adversely Affect" is proposed for both species based on habitat found although no species found. NCDOT is currently awaiting a concurrence from the US Fish and Wildlife (see attached request for concurrence, letter dated May 13, 2004). 2 The USFWS listing of protected species and current Biological Conclusions are listed in the following table. Federallv Protected Species for RockinLyham Countv Common Name Scientific Name Status Habitat Biological Conclusion James Pleurobema Endangered YES May Affect, Not spinymussel collina Likely to Adversely Affect Smooth Echinacea Endangered YES May Affect, Not coneflower laevigata Likely to Adversely Affect Endangered denotes a species that is in danger of extinction throughout all or a significant portion of its range. AVOIDANCE AND MINIMIZATION Avoidance examines all appropriate and practicable possibilities of averting impacts to "Waters of the United States". The NCDOT is committed to incorporating all reasonable and practicable design features to avoid and minimize jurisdictional impacts, and to provide full compensatory mitigation of all remaining, unavoidable jurisdictional stages; minimization measures were incorporated as part of the project design. The impacts to Jones Creek are minimized by replacing Bridge No. 84 with a new bridge that will span the creek at approximately the same location and roadway elevation. Impacts are further minimized to the Jones Creek UT by burying the invert of the new pipe one foot beneath the streambed. REGULATORY APPROVALS Section 404 Permit: It is anticipated that the temporary stream diversion will be authorized under Section 404 Nationwide Permit 33. We are therefore requesting the issuance of a Nationwide Permit 33 for this diversion. The remaining aspects of the project are*being processed by the Federal Highway Administration as a "Categorical Exclusion" in accordance with 23 CFR 771.115(b). The NCDOT requests that these activities be authorized by a Nationwide Permit 23 (FR number 10, pages 2020-2095; January 15, 2002). Section 401 Permit: We anticipate 401 General Certification numbers 3403 and 3366 will apply to this project. All general conditions of the Water Quality Certifications will be met. Therefore, in accordance with 15A NCAC 2H, Section .0500(a) and 15A NCAC 2B.0200 we are providing two copies of this application to the North Carolina Department of Environmental and Natural Resources, Division of Water Quality, for their notification.

No species were found during the most recent site visits therefore a biological conclusion of "May Affect, Not Likely to Adversely Affect" was determined for both the smooth coneflower and the James Spiny Mussel. SURVEY METHODOLOGY A plant-by-plant survey was conducted for the smooth coneflower on July 11, 2002 during the optimal survey window. Prior to the survey, the investigators visited a known population of the smooth coneflower to have a fresh visual of the plant that will be surveyed. The survey for the coneflower consisted of a search for single flowers with drooping pink/purple petals on a long stem. The smooth coneflower was not observed during the site investigation in the preferred habitat within the project study area. A total of 5 person-hours were spent conducting the survey. The Catena Group conducted a freshwater mussel survey in September 2003. (Please see attached report.) Visual and tactical survey methods were used. Mussel surveys were conducted 400 meters downstream of the project crossing and 100 meters upstream of the project crossing. No mussels were observed in the entire surveyed area. A total of 3 person-hours were spent conducting the survey.

Savidge 410-13 Millstone Drive Hillsborough, NC 27278 (919) 732-1300 INTRODUCTION The North Carolina Department of Transportation proposes to replace bridge # 84 over Jones Creek on SR 2579 in eastern Rockingham County, North Carolina, TIP No. B-3696 (Figure 1). Jones Creek occurs within the Dan River Subbasin of the Roanoke River Basin. The federally endangered James spinymussel (Pleurobema collina) is known to occur in the Dan River Subbasin. Other rare freshwater mussel species known to occur in the Dan River Subbasin in Rockingham County include the green floater (Lasmigona subviridis), and the notched rainbow (Villosa constricta). The green floater is a Federal Species of Concern and is considered Endangered in North Carolina. The notched rainbow is considered Special Concern. WATERS IMPACTED: Jones.Creek The proposed project will impact Jones Creek, which arises approximately 2.5 miles west of the project crossing and flows northeast into Hogans Creek 5 miles downstream of the crossing. Hogan Creek flows another 18 miles to the northeast before entering the Dan River in northern Caswell County. The stream channel in the surveyed area is very incised with a stream width of approximately 5 meters (16.4 feet) and banks approximately 3.5 meter (11.5) high. The streambanks are-unstable and severely eroded in places. The substrate within the stream is predominately shifting sand and gravel with clay banks. SPECIES DESCRIPTION Pleurobema collina (James spinymussel) Status: Endangered Listed: 7/22/88 Characteristics The James spinymussel (JSM) was discovered in the Calfpasture River (of the James River Basin) by T. A. Conrad and originally described as Unio collinus (Conrad 1837). Various workers (See USFWS 1990 for synonyms) have subsequently placed this species in a number of different genera. Turgeon et al. (1988) placed the James spinymussel in the genus Pleurobema. The taxonomic history of this species is described fully in Clarke and Neves (1984). The JSM is a small mussel that is reported to reach a maximum size of 70 mm. A specimen collected in the Dan River was measured at 74 mm in length. The shells of small individuals (<40 mm) are subrhomboid in shape with an obliquely subtruncated posterior with widely spaced concentric striations. The periostracum (outside layer of shell) is shiny and straw yellow with prominent growth rings. Faint brownish rays are rarely present. One to three short, but prominent spines are occasionally present on each valve. With age, the shell becomes more ovate, or even arcuate, the periostracum becomes brownish to black and any spines that were once present are lost.

The nacre (inner shell) is white with occasional bluish suffusions. The foot and mantle of live specimens are light orange in color. (USFWS 1990, Clarke and Neves 1984, Johnson 1970). Internal anatomy is detailed in Clarke and Neves (1984). The JSM and the Tar spinymussel (TSM) share many morphological wits, but are clearly distinct species. The TSM has been described as having intermediate characteristics between the small, short-spined JSM and the large, long-spined Altamaha spinymussel (USFWS 1992x, USFWS 1990). Internal anatomical differences between the two species are described in Clarke and Neves (1984). Tar spinymussels can have up to 12 spines (USFWS 1992) and tend to have spines more often than JSMs. Clarke and Neves (1984) state that most specimens of JSM "never develop spines". The JSM observed from the Dan River and Mayo River (>250 individuals, Tim Savidge Personal Observations) more often than not have spines present and as many as 8 spines have been observed on one individual. Spine length in these specimens observed is also greater than has been reported in specimens from the James River system. These differences between the Dan/Mayo River and James River populations suggest that spine number and length may be more related to environmental factors than genetic traits. Knowledge of the reproductive biology is limited to thesis research at Virginia Polytechnic Institute and State University (Hove 1990, Hove and Neves 1989). Like nearly all freshwater mussel species the reproductive strategy of the JSM involves a larval stage (glochidium), that becomes a temporary obligatory parasite on a fish. Many mussel species have specific fish hosts that must be present to complete their life cycle. Based upon laboratory infestation experiments, Hove (1990) identified seven fish species all in the family Cyprinidae (minnows) as potential fish hosts for the JSM. McMahon and Bogan (2001) and Penmak (1989) can be consulted for a general overview of freshwater mussel reproductive biology. Distribution and Habitat Requirements Previously this mussel was believed to be endemic to the James River system, with a widespread distribution within the basin (USFWS 1990, Clarke and Neves 1984). When the Recovery Plan for this species was adopted, it was believed to have been extirpated from 90% of its historic distribution. Since the discovery in the Dan River in the fall of 2000, extensive surveys for mussel fauna have been conducted in the Dan River drainage in Stokes, Rockingham and Caswell Counties North Carolina. . The apparent range (- 36 river-miles) of the spinymussel in the Dan River. extends from the North Carolina/Virginia border near the first bridge crossing in North Carolina (Flippin Rd, SR 1416) in northwest Stokes County downstream to at least SR 1695 (Dodgetown Road), below the town of Danbury in central Stokes County. The JSM has not been found in the Dan River in Rockingham and Caswell Counties. The species has also been found in the South Fork Mayo River in Patrick County Virginia downstream into the Mayo River in Rockingham County North Carolina (an approximately 16-mile reach). Because it was discovered only recently in the Dan River '1'(Y;-freshwater Mussel Survcy Sk 2579 over loncs Creek, Rockingham County, NC drainage, further research is needed to determine the historic distribution of the JSNI in the Dan River drainage. A description of chemical and physical conditions at sites currently and historically supporting the JSM is given in Clarke and Neves (1984) and Boss and Clench (1967). The habitat is generally described as runs with moderate current, with sand, gravel and cobble substrata. Individuals from the Dan/Mayo population have been found in a variety of substrates from silt/sand, to sand, gravel, cobble, bedrock crevices and sand surrounded by boulders, with a variety of flow patterns from slack pools, to runs with moderate to swift currents (personal observations). The hardness of the water is believed to be a significant requirement for this species, with a minimum hardness value of (>50 ppm CaC03) (Clarke and Neves 1984). Threats to Species The cumulative effects of several factors, including sedimentation, point and non- point discharge, stream modification (impoundment's, channelization etc.), coupled with the apparent restricted range, are believed to have contributed to the decline of this species throughout its range (USFWS 1990). When mussel populations are reduced to a small number of individuals and are restricted to short reaches of isolated streams, they are extremely vulnerable to extirpation from a single catastrophic event or activity (Strayer et al. 1996). Catastrophic events may consist of natural events such as flooding, or drought as well as human influenced events such as toxic spills associated with highways or railroads. Siltation resulting from improper erosion control of various land usage, including agricultural, forestry and development activities has been recognized as a major contributing factor to degradation of mussel populations (USFWS 1996). Siltation has been documented to be extremely detrimental to mussel population's by degrading substrate and water quality, increasing potential exposure to other pollutants and by direct smothering of mussels (Ellis 1936, Marking-and Bills 1979). Sediment accumulations of less than 1 inch have been shown to cause high mortality in most mussel species (Ellis 1936). In Massachusetts, a bridge construction project decimated a population of the endangered dwarf-wedge mussel (Alasmidonta heterodon), because of accelerated sedimentation and erosion (Smith 1981). Sewage treatment effluent has been documented to significantly affect the diversity and abundance of mussel fauna (Goudreau et al. 1988). Goudreau et al. (1988) found that recovery of mussel populations might not occur for up to two miles below points of chlorinated sewage effluent. Clarke and Neves (1984) suggested that sewage and industrial pollution might have contributed to the extirpation of the JSM from the North River in Virginia. Based on field observations the municipal wastewater treatment plants located in Danbury on the Dan River and in Stoneville on the Mayo River appear to contribute to a reduction of mussels, including the JSM in the respective waterbodies (personal observations). TC(i-Fresh water Mussel Survey 4 SR 2579 over.lancs Creek, Rockingham County, Iv(; The impact of impoundments on freshwater mussels has been well-documented (USFWS 1992a, Neves 1993). Construction of dams transforms lotic habitats into lentic habitats, which results in changes with aquatic community composition. These changes associated with inundation adversely affect both adult and juvenile mussels as well as fish community structure, which could eliminate possible fish hosts for glochidia (Fuller 1974). Two impoundments, Avalon Dam and Mayo Dam are located on the Mayo River. These two facilities, created for hydroelectric purposes, have effected distribution of mussels including the JSM in the Mayo River (personal observations). The introduction of exotic species such as the Asiatic clam (Corbicula fluminea) and zebra mussel (Dreissena polymorpha) has also been shown to pose significant threats to native freshwater mussels. The Asiatic clam is now established in most of the major river systems in the United States (Fuller and Powell 1973), including those streams still supporting surviving populations of the JSM. Concern has been raised over pompetitive interactions for space, food and oxygen with this species and native mussels, possibly at the juvenile stages (Neves and Widlak 1987, Alderman 1997). The Asian clam was observed to be abundant within the Dan and Mayo Rivers (personal observations). The zebra mussel, native to the drainage basins of the Black, Caspian and Aral Seas, is an exotic freshwater mussel that was introduced into the Great Lakes in the 1980s and has rapidly expanded its range into the surrounding river basins, including those of the South Atlantic slope (O'Neill and MacNeill 1991). This species competes for food resources and space with native mussels, and is expected to contribute to the extinction of at least 20 freshwater mussel species if it becomes established throughout most of the eastern United States (USFWS 1992b). This species has not been reported from any waterbody that supports the JSM. SURVEY EFFORTS Jones Creek is a perennial stream that could potentially provide habitat for the James spinymussel and thus surveys for this and other mussel species were conducted for NCDOT. Pre Survey Investigation Prior to conducting in-stream surveys, a review of any survey work that had taken place in Jones Creek was performed. Sources consulted include the North Carolina Natural Heritage Program (NHP) systematic inventory (database) of rare plant and animal species, and the North Carolina Wildlife Resources Commission. The pre-survey searches did not reveal any records of rare freshwater mussel species from Jones Creek. Mussel Surveys for this Project Tim Savidge, Tom Dickinson and Shannon Simpson of The Catena Group, Inc., visited Jones Creek on September 26, 2003. Mussel surveys were conducted from a TC(J-Freshwater Mussel Survey SR 2579 over Jon,,;.,; Creek, Rockingham County, NC point approximately 400 meters downstream of the project crossing to a point approximately 100 meters upstream. illtethodolow and Results Visual surveys were conducted using visual (batiscopes) and tactile methods. The water was turbid during the site visit, but not to the level to preclude visual surveys. Water level ranged from <6 inches to 3.0 feet, averaging 2 foot. No mussels were observed in the entire surveyed reach,.in 3 person-hours of survey time. The introduced Asian clam (Corbicula fluminea) is present but not abundant in the creek. Discussion No mussel species were found in Jones Creek during the survey efforts. It is very unlikely that any tpussel species will be impacted by the proposed action. It can be concluded that project construction is "Not Likely to Adversely Affect" the James spinymussel. It is recommended that NCDOT receive concurrence from the U. S. Fish and Wildlife Service with these findings. LITERATURE CITED Alderman, J.M. 1997. Monitoring the Swift Creek freshwater mussel community. Pages 98-107 in K.S. Cummings, A.C. Buchanan, C.A.

CATEGORICAL EXCLUSION ACTION CLASSIFICATION FORM TIP Project No. B-3696 State Project No. 8.2511001 Federal Project No. BRZ-2579 (1) A. Project Description: This project proposes to replace Bridge No. 84 on SR 2579 over Jones Creek in Rockingham County. The bridge will be replaced with a 70-foot (21.3- m) long bridge in approximately the same location and roadway elevation as the existing bridge. The cross section of the new bridge will include two 12-foot (3.6-m) lanes with 4-foot (1.2-m) offsets. Approach work will consist of resurfacing and tieing into the existing alignment for approximately 500 feet (152.4 m) on either side of the new bridge. Guardrail will be installed where warranted. Traffic will be detoured along surrounding roads during construction. B. Purpose and Need: Bridge No. 84 has a sufficiency rating of 19.0 out of a possible 100. The deck and substructure of this 50-year old bridge are in poor condition. Therefore, the bridge needs to be replaced. Rehabilitation is not practical due to the age of the structure and a timber substructure. C. Proposed Improvements: The following Type II improvements which apply to the project are circled: 1. Modernization of a highway by resurfacing, restoration, rehabilitation, reconstruction, adding shoulders, or adding auxiliary lanes (e.g., parking, weaving, turning, climbing). a. Restoring, Resurfacing, Rehabilitating, and Reconstructing pavement (3R and 4R improvements) b. Widening roadway and shoulders without adding through lanes c. Modernizing gore treatments d. Constructing lane improvements (merge, auxiliary, and turn lanes) e. Adding shoulder drains f. Replacing and rehabilitating culverts, inlets, and drainage pipes, including safety treatments g. Providing driveway pipes h. Performing minor bridge widening (less than one through lane) 2. Highway safety or traffic operations improvement projects including the installation of ramp metering control devices and lighting. a. Installing ramp metering devices b. Installing lights c. Adding or upgrading guardrail d. Installing safety barriers including Jersey type barriers and pier protection e. Installing or replacing impact attenuators f. Upgrading medians including adding or upgrading median barriers g. Improving intersections including relocation and/or realignment h. Making minor roadway realignment i. Channelizing traffic j. Performing clear zone safety improvements including removing hazards and flattening slopes k. Implementing traffic aid systems, signals, and motorist aid 1. Installing bridge safety hardware including bridge rail retrofit 3O Bridge rehabilitation, reconstruction, or replacement or the construction of grade separation to replace existing at-grade railroad crossings. a. Rehabilitating, reconstructing, or replacing bridge approach slabs b. Rehabilitating or replacing bridge decks c. Rehabilitating bridges including painting (no red lead paint), scour repair, fender systems, and minor structural improvements dO Replacing a bridge (structure and/or fill) 4. Transportation corridor fringe parking facilities. 5. Construction of new truck weigh stations or rest areas. 6. Approvals for disposal of excess right-of-way or for joint or limited use of right-of-way, where the proposed use does not have significant adverse impacts. 7. Approvals for changes in access control. 8. Construction of new bus storage and maintenance facilities in areas used predominantly for industrial or transportation purposes where such construction is not inconsistent with existing zoning and located on or near a street with adequate capacity to handle anticipated bus and support vehicle traffic. 9. Rehabilitation or reconstruction of existing rail and bus buildings and ancillary facilities where only minor amounts of additional land are required and there is not a substantial increase in the number of users. 10. Construction of bus transfer facilities (an open area consisting of passenger shelters, boarding areas, kiosks and related street improvements) when located in a commercial area or other high activity center in which there is adequate street capacity.for projected bus traffic. 11. Construction of rail storage and maintenance facilities in areas used predominantly for industrial or transportation purposes where such 2 construction is not inconsistent with existing zoning and where there is no significant noise impact on the surrounding community. 12. Acquisition of land for hardship or protective purposes, advance land acquisition loans under section 3(b) of the UMT Act. Hardship and protective buying will be permitted only for a particular parcel or a limited number of parcels. These types of land acquisition qualify for a CE only where the acquisition will not limit the evaluation of alternatives, including shifts in alignment for planned construction projects, which may be required in the NEPA process. No project development on such land may proceed until the NEPA process has been completed. D. Special Project Information: Estimated Costs: Total Construction $ 575,000 Right of Way $ 27,000 Total $ 602,000 Estimated Traffic: Current - 1300 vpd Year 2025 - 2000 vpd TTST - 1% Dual - 2% Proposed Typical Cross Section: The approach roadway cross section will include two 12-foot (3.6-m) lanes and 6-foot (1.8-m) grassed shoulders. The shoulder width will be increased to 9 feet (2.7-m) where guardrail is installed. Design Speed: 60 mph (100 km/h) (Design exception for vertical alignment may be required.) Functional Classification: Rural Minor Collector Division Office Comments: The Division Seven Construction Office concurs in the recommendation to replace Bridge No. 84 in approximately the same location as the existing bridge while detouring traffic along surrounding roads. Bridge Demolition: Bridge No. 84 contains three spans totaling 53 feet (16.2 m) in length. The entire bridge is composed of timber. Therefore, Bridge No. 84 will be removed without dropping any of its components into Waters of the United States. 3 I E.

(2) The smooth coneflower grows in meadows, open woodlands, glades, cedar barrens, roadsides, power line rights-of-way, clearcuts, and dry limestone bluffs. Plants usually grow in soil derived from calcareous parent material. Optimal sites occur in areas with abundant sunlight and little competition from other herbaceous plants. Natural fires and large herbivores are important to the maintenance of the smooth coneflower habitat. BIOLOGICAL CONCLUSION: NO EFFECT The open woodlands, roadsides, and clearcuts required by the smooth coneflower are present in the project study area. A plant-by-plant survey was conducted for the smooth coneflower on July 11, 2002 during the optimal survey window. The smooth coneflower was not observed during the site investigations in its prefered habitat within the project study area. Additionally, a review of the NHP database on March 6, 2002 revealed no records of existing populations of the smooth coneflower within 1.0 mi (1.6 km) of the project study area. Therefore, project construction will not affect the smooth coneflower. 6 G.

TIP No. B-3696, Rockingham County, ER 00-8456 On March 7, 2000, April Montgomery 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. Based upon our review of the photographs and the information discuss 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 and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

Project No. 1960024-M50.99 Page ii 1.0 INTRODUCTION The following Natural Resources Technical Report is submitted to assist in preparation of a Categorical Exclusion (CE) for the proposed project. The project is located in southeastern Rockingham County (Figure 1). 1.1 Project Description The proposed project calls for the replacement of Bridge No. 84 on State Road 2579 over Jones Creek. The project length is approximately 1,000.00 ft (304.80 m). 1.2 Purpose The purpose of this technical report is to inventory, catalog, and describe the various natural resources that may be impacted by the proposed action. Recommendations are made for measures that will minimize resource impacts. These descriptions and estimates are relevant only in the context of the recommended project area. If the project area changes, additional field investigations may need to be conducted. 1.3 Methodology Research was conducted before field investigations. Information sources used in this pre-field investigation of the project area include: Williamsburg (1972) U.S. Geological Survey (USGS) quadrangle map, Williamsburg (1997) U.S. Fish and Wildlife Service (FWS) National Wetlands Inventory Map, Natural Resources Conservation Service (MRCS) soil maps, and North Carolina Department of Transportation (NCDOT) aerial photographs of the project area (1:1,200). Water resource information was obtained from the Department of Environment, Health, and Natural Resources publications (DEHNR, 1996). Federal and State protected species information was gathered from the U.S. Fish and Wildlife Service (FWS) list of protected species and species of concern, and the N.C. Natural Heritage Program (NHP) database of rare species and unique habitats. LandMark Design Group, Inc. (LandMark) environmental scientists Corn Faquin and Linda Diebolt conducted field surveys along the proposed alignment on March 11, 2002. Plant communities and their associated wildlife were identified and recorded. Wildlife identification involved using one or more of the following observation techniques: active search and capture, visual observations, and identification of characteristic signs of wildlife (sounds, scat, tracks, and burrows). Jurisdictional wetland delineations were performed utilizing the criteria prescribed in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987).

Soils and availability of water directly influence composition and distribution of flora and fauna in any biotic community. The project area lies within the Piedmont Physiographic Province. The topography in this section of Rockingham County is characterized by nearly level areas, ridgetops, side slopes, and stream floodplains. Project elevation is approximately 600.00 ft (182.88 m) above mean sea level (msl). 2.1 Soils Three soil series occur within the project area: Chewacla loam, Pacolet sandy clay loam, and Madison sandy clay loam. Soil phase description information was obtained from the Soil Survey of Rockingham County, North Carolina (1992). They are as follows: Chewacla loam (non-hydric) is a poorly drained soil found in nearly level or slightly concave areas parallel to major streams on floodplains. Permeability is moderate and the seasonal high water table occurs 0.50 to 1.50 ft (0.15 to 0.46 m) below the surface. Wetness and flooding are the major limitations for this soil type. North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 2 • Pacolet sandy clay loam (non-hydric) with 8.00 to 15.00 percent slopes is a well-drained soil found on long, narrow, convex side slopes. Permeability is moderate. Slope and the clayey subsoil are the main limitations for this soil type. • Madison sandy clay loam (non-hydric) with 8.00 to 15.00 percent slopes is a well-drained soil found in lower areas on narrow, convex side slopes. Permeability is moderate. The high content of clay in the surface layer is the major limitation for this soil type. 2.2 Water Resources This section contains information concerning those water resources within the project area. Water resource information encompasses physical aspects of the resource, its relationship to major water systems, Best Usage Standards, and water quality of the resources. Surface water resources and minimization methods are also discussed. 2.2.1 Surface Water Characteristics Jones Creek and an unnamed tributary to Jones Creek are surface water resources within the project area. These water resources are located in sub-basin 03-02-03 of the Roanoke River Basin. The average baseflow width of Jones Creek is approximately 15.00 ft (4.57 m). Average depth is approximately 1.50 ft (0.46 m). The substrate of Jones Creek was observed to be composed of silt. LandMark observed the flow within Jones Creek to be moderate and the clarity to be fair. The average baseflow width of the unnamed tributary to Jones Creek is 7.00 ft (2.13 m), with an average depth of 1.00 ft (0.30 m). The substrate of the unnamed tributary was observed to be composed of silt and pebbles. LandMark observed the flow within the tributary to be moderate and the clarity to be fair. Several storm water drainage ditches flow into the unnamed tributary to Jones Creek and are located within the project area; however, no water was present in the ditches at the time of LandMark's site reconnaissance. 2.2.2 Best Usage Classification All streams have been assigned a best usage classification by the N.C. Division of Water Quality (DWQ). The classification of Jones Creek in the project area is C (DEHNR, 1996). Class C refers to waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Neither High Quality Waters (HQW), Water Supplies (WS-I: undeveloped watersheds or WS-II: predominately undeveloped watersheds) nor Outstanding Resource Waters (ORW) occur within 1.00 mi (1.61 km) of the project area. 2.2.3 Water Quality The DWQ has initiated a basin-wide approach to water quality management for each of the 17 river basins within the state. To accomplish this goal the DWQ collects biological, chemical, and physical North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 3 data that can be used in basinwide assessment and planning. All basins are reassessed every five years. Before implementation of the basinwide approach to water quality management, the Benthic Macroinvertebrate Ambient Network (BMAN) assessed water quality by sampling for benthic macroinvertebrate organisms at fixed monitoring sites throughout the state. There is a BMAN station (DEM No. 22-50-3) located on Jones Creek at State Road 2632 in Rockingham County within 1.00 mi (1.61 km) of the project area. The station received a bioclassification rating of "good" in January 1992. Many benthic macroinvertebrates have life cycle stages that can last from six months to one year. Therefore, the adverse effects of a toxic spill may not be overcome until the next generation. Different taxa of macroinvertebrates have different tolerances to pollution; therefore, long-term changes in water quality conditions can be identified by population shifts from pollution sensitive to pollution tolerant organisms (and vice versa). Overall, the species present, the population diversity, and the biomass are reflections of long-term water quality conditions. In North Carolina, point source dischargers are permitted through the National Pollutant Discharge Elimination System (NPDES) Program. Permits are required for all point source discharges. There is no point source discharger on Jones Creek within 1.00 mi (1.61 km) of the project area. 2.2.4 Ecological Impacts Replacing an existing structure in the same location with a road closure during construction is usually preferred. It poses the least risk to aquatic organisms and other natural resources. Bridge replacement at a new location usually results in greater impacts. Usually, project construction does not disturb the entire right-of-way; therefore, actual impacts will be less than reported in Table 1 of Section 3.3. ' Project construction may result in the following impacts to surface waters: 1. Increased sedimentation and siltation from demolition debris and/or erosion resulting from vegetation removal and soil disturbance during construction, 2. Changes in light incidence and water clarity due to increased sedimentation and vegetation removal, 3. Alteration of water levels and flows due to interruptions and/or additions to surface and ground water flow from construction, 4. Changes in water temperature due to increased sun and wind exposure resulting from streamside vegetation removal, 5. Increased nutrient loading from the stormwater runoff of areas disturbed during construction, and/or 6. Increased input of toxic compounds from demolition, construction, toxic spills, and highway runoff. North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 4 Precautions must be taken to minimize impacts to water resources in the project area. The NCDOT's Best Management Practices (BMP) for the Protection of Surface Waters must be strictly enforced during the construction stage of the project. Guidelines for these BMPs include, but are not limited to minimizing built upon area and diverting stormwater away from surface water supply waters as much as possible. Provisions to prevent water resource contamination by toxic substances during the demolition and construction phases must also be strictly enforced. 3.0 BIOTIC RESOURCES Biotic resources include aquatic and terrestrial ecosystems. This section describes those ecosystems encountered in the project area, as well as, the relationships between flora and fauna within these ecosystems. Composition and distribution of biotic communities throughout the project area are reflective of topography, hydrologic influences, and past and present land uses in the project area. Descriptions of the terrestrial systems are presented in the context of plant community classifications and follow descriptions presented by Schafale and Weakley (1990) where possible. Dominant flora and fauna observed, or likely to occur, in each community are described and discussed. Scientific nomenclature and common names (when applicable) are provided for each plant and animal species described. Plant taxonomy generally follows Radford et al. (1968). Animal taxonomy follows Martof et al. (1980), Potter et al. (1980), and Webster et al. (1985). Subsequent references to the same organism will include the common name only. Fauna observed during the site visits are denoted with an asterisk (*). Published range distributions and habitat analysis are used in estimating fauna expected to be present within the project area. . 3.1 Terrestrial Communities Two distinct terrestrial communities are identified in the project area (Figure 2): Dry Oak-Hickory Forest and maintained/disturbed. Community boundaries within the project area are well defined as shown in Figure 2. Faunal species likely to occur within the project area will exploit all community types for shelter, foraging opportunities, and/or as wildlife corridors. 3.1.1 Dry Oak-Hickory Forest The Dry Oak-Hickory Forest occurs throughout the entire project area with the exception of the maintained/disturbed community adjacent to the existing roadway (see Figure 2). The Dry Oak- Hickory Forest consists of mature hardwood areas, immature hardwood areas, and a scrub/shrub area. The canopy is dominated by sycamore (Platanus occidentalis), yellow poplar (Liriodendron tulipifera), short-leaf pine (Pinus echinata), red cedar (Juniperus virginiana), and white oak (Quercus alba) with river birch (Betula nigra) adjacent to Jones Creek and the unnamed tributary to Jones Creek. Dominant sapling species include sycamore, yellow poplar, red maple (Acer rubrum), and beech (Fagus grandifolia). The shrub layer consists of flowering dogwood (Cornus jlorida) and privet (Ligustrum sp.), with strawberry bush (Euonymus americanus) adjacent to Jones Creek and the unnamed tributary to Jones Creek. The herbaceous and vine layers are sparse and consist of several species of greenbrier (Smilax sp.), Japanese honeysuckle (Lonicera japonica), poison ivy (Toxicodendron radicans), and blackberry (Rubus argutus). North Carolina Department of Transportation TIP #.• B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 5 Avian species associated with the Dry Oak-Hickory Forest include field sparrow (Spizella pusilla), Carolina chickadee (Parus carolinensis), chestnut-sided warbler (Dendroica pensylvanica), common crow* (Corvus brachyrhynchos), and several species of songbirds*. Wildlife species associated with this community type include white-tailed deer (Odocoileus virginianus), gray squirrel (Sciurus carolinensis), southeastern shrew (Sorex longirostris), eastern cottontail (Sylvilagus floridanus), eastern chipmunk (Tamias striatus), and raccoon (Procyon lotor). 3.1.2 Maintained/Disturbed The maintained/disturbed community occurs along the roadside shoulders of State Road 2579 for the entire length of the project area. The maintained/disturbed community is predominantly vegetated by grass (Festuca sp.). Faunal species frequenting the maintained/disturbed community will include those inhabiting the Dry Oak-Hickory Forest. 3.2 Aquatic Communities Jones Creek and an unnamed tributary to Jones Creek are aquatic communities located within the project area. Physical characteristics of a water body and the condition of the water resource influence faunal composition of aquatic communities. Terrestrial communities adjacent to a water resource also greatly influence aquatic communities. Vegetation along the banks of Jones Creek and the tributary to Jones Creek includes those species present in the Dry Oak-Hickory Forest. Fauna associated with these aquatic communities include various invertebrate and vertebrate species. Aquatic species likely to occur in Jones Creek include gizzard shad (Dorosoma cepedianum), silver redhorse (Moxostoma anisurum), grass carp (Ctenopharyngodon idella), creek chub (Semotilus atromaculatus), eastern ribbon snake (Thamnophis sauritus), pickerel frog (Rana palustris), and two- lined salamander'(Eurycea bislineata). Invertebrates that would be present include various species of caddisfly (Trichoptera), mayfly (Ephemeroptera), crayfish (Decapoda), dragonfly (Odonata), and damselfly (Odonata). 3.3 Habitat Summary Construction of the subject project will have various impacts on the biotic resources described. Any construction related activities in or near these resources have the potential to impact biological functions. Table 1 quantifies the habitat communities within the project area. Table 1.

Project No. 196002=1-M50.99 Page 6 Plant communities found within the proposed project area serve as nesting and sheltering habitat for various wildlife species. Replacing Bridge No. 84 and its associated improvements may reduce habitat for some faunal species. However, due to the size and scope of this project, it is anticipated that impacts to fauna will be minimal. Areas modified by construction (but not paved) will become road shoulders and early succession habitat. Reduced habitat may displace some wildlife further from the roadway while attracting other wildlife by the creation of early successional habitat. Animals temporarily displaced by construction activities may repopulate areas suitable for the species. Aquatic communities are sensitive to even small changes in their environment. Stream channelization, scouring, siltation, sedimentation, and erosion from project-related work may affect water quality and biological constituents. Although direct impacts may be temporary, environmental impacts from these construction processes may result in long term or irreversible effects. Impacts often associated with in-stream construction include increased channelization and scouring of the streambed. In-stream construction alters the stream substrate and may remove streamside vegetation at the site. Disturbances to the substrate will produce siltation, which in excessive amounts can clog the gills and/or feeding mechanisms of benthic organisms (sessile filter-feeders and deposit- feeders), fish, and amphibian species. Benthic organisms may also be covered by excessive amounts of sediment. Some of these organisms may be slow to recover or repopulate a stream. The removal of streamside vegetation and placement of fill material at the construction site alters the terrain. Alterations of the stream bank enhance the likelihood of erosion and sedimentation. Revegetation stabilizes and holds the soil thus mitigating these processes. Erosion and sedimentation carry soils, toxic compounds, and other materials into aquatic communities at the construction site. These processes increase turbidity and can cause the formation of sandbars at the site and downstream, thereby altering water flow and the growth of vegetation. Streamside clearing also leads to more direct sunlight penetration causing elevations in water temperatures, which may affect some species. Based on the potential for increased sedimentation, it is recommended that silt curtains be used during construction. 4.0 JURISDICTIONAL TOPICS This section provides descriptions, inventories, and impact analysis pertinent to two important issues: "Waters of the United States" and rare and protected species. 4.1 Waters of the United States Surface waters and jurisdictional wetlands fall under the broad category of "Waters of the United States", as defined in Section 33 of the Code of Federal Register (CFR) Part 328:3. Wetlands, as defined in 33 CFR 328.3, are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted to life in saturated conditions. Any action that proposes to place fill into these areas falls within the jurisdiction of the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean Water Act (33 U.S.C. 1344). North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 7 4.1.1 Wetlands and Surface Waters Potential wetland communities were investigated pursuant to the 1987 Corps of Engineers Wetlands Delineation Manual. The three-parameter approach was used. Hydric soils, hydrophytic vegetation, and certain specific hydrologic characteristics must all be present for an area to be considered a wetland. Wetlands are not present within the project area. Jones Creek and an unnamed tributary to Jones Creek are surface waters under Section 404 of the Clean Water Act (33 USC 1344). Jones Creek covers 0.03 ac (0.01 ha) and 80.00 if (24.38 lm) of the project area. The unnamed tributary to Jones Creek covers 0.01 ac (0.004 ha) and 20.00 if (6.10 lm) of the project area. Discussion of the biological, physical, and water quality aspects of all surface waters in the project area are presented in previous sections of this report. 4.1.2 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. Nationwide Permit 23 (33 CFR 330.5(a) (23)) is likely to be applicable for all impacts to "Waters of the United States" resulting from the proposed project. This permit authorizes activities undertaken, assisted, authorized, regulated, funded, or financed in whole or part by another federal agency or department where that agency or department has determined that pursuant to the -Council on Environmental Quality regulation for implementing the ? procedural provisions of the National Environmental Policy Act: • The activity, work, or discharge is categorically excluded from environmental documentation because it is included within a category of actions which neither individually nor cumulatively have a significant effect on the human environment, and • The office of the Chief of Engineers has been furnished notice of the agency's or department's application for the categorical exclusion and concurs with that determination. This project will also require a 401 Water Quality Certification from the DWQ before 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. 4.1.3 Bridge Demolition Bridge No. 84 has three spans totaling 53.00 ft (16.15 m) in length. The entire bridge is composed of timber. Therefore, Bridge No. 84 will be removed without dropping any of its components into "Waters of the United States". North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 8 T 7 4.1.4 Mitigation The COE has adopted, through the Council on Environmental Quality (CEQ), a wetland mitigation policy that embraces the concept of "no net loss of wetlands" and sequencing. The purpose of this policy is to restore and maintain the chemical, biological, and physical integrity of "Waters of the United States," specifically wetlands. Mitigation of wetland impacts has been defined by the CEQ to include avoiding impacts (to wetlands), minimizing impacts, rectifying impacts, reducing impacts over time, and compensating for impacts (40 CFR 1508.20). Each of these three aspects (avoidance, minimization, and compensatory mitigation) must be considered sequentially. 4.1.4.1 Avoidance Avoidance mitigation examines all appropriate and practicable possibilities of averting impacts to "Waters of the United States." According to a 1990 Memorandum of Agreement (MOA) between the Environmental Protection Agency (EPA) and the COE, in determining "appropriate and practicable" measures to offset unavoidable impacts, such measures should be appropriate to the scope and degree of those impacts and practicable in terms of cost, existing technology, and logistics in light of overall project purposes. 4.1.4.2 Minimization Minimization includes the examination of appropriate and practicable steps to reduce the adverse impacts to "Waters of the United States." Implementation of these steps will be required through project modifications and permit conditions. Minimization typically focuses on decreasing the footprint of the proposed project through the reduction of median widths, right-of-way widths, fill slopes, and/or road shoulder widths. Other practical mechanisms to minimize impacts to "Waters of the United States" crossed by the proposed project include: strict enforcement of sedimentation control BMP's for the protection of surface waters during the entire life of the project; reduction of clearing and grubbing activity; reduction/elimination of direct discharge into streams; reduction of runoff velocity; re-establishment of vegetation on exposed areas; judicious pesticide and herbicide usage; minimization of "in-stream" activity; and litter/debris control. 4.1.4.3 Compensatory Mitigation Compensatory mitigation is not normally considered until anticipated impacts to "Waters of the United States" have been avoided and minimized to the maximum extent practicable. It is recognized that "no net loss of wetlands" functions and values may not be achieved in every permit action. Appropriate and practicable compensatory mitigation may be required for unavoidable, adverse impacts that remain after all appropriate and practicable minimization has been performed. Compensatory actions often include restoration, creation, and enhancement of "Waters of the United States." Such actions should be undertaken in areas adjacent to or contiguous to the discharge site whenever practicable. Compensatory mitigation is not usually necessary with a Nationwide Permit No. 23. Impact thresholds for mitigation are as follows: North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 9 • 0.10 to 1.00 ac (0.04 to 0.40 ha) of wetland impacts may require mitigation; • 1.00 ac (0.40 ha) or more of wetland impacts will require mitigation; • 150.00 if (45.721m) or more of stream impacts will require mitigation. 4.2 Rare and Protected Species Some populations of flora and fauna have been in, or are in, the process of decline due to either 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 U.S. Fish and Wildlife Service (FWS). Other species may receive additional protection under separate state laws. 4.2.1 Federally Protected Species Plants and animals with federal classifications of Endangered (E), Threatened (T), Proposed Endangered (PE), and Proposed Threatened (PT) are protected under the provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. As of April 12, 2001, the FWS lists two federally protected species for Rockingham County (Table 2). A brief description of the characteristics and habitat requirements for these species along with a conclusion regarding potential project impacts follows. Table 2. Federally protected species of Rockingham County. Scientific Name Common Name Federal Status Echinacea laevigata Smooth coneflower Endangered Pleurobema collina James spinymussel Endangered Endangered - A taxon "in danger of extinction throughout all or a significant portion of its range." Echinacea laevigata (smooth coneflower) Endangered Plant Family_ Asteraceae Federally Listed: December 9, 1991 The smooth coneflower was once found in all of the Atlantic Coast states from Pennsylvania to Georgia, on the Gulf Coast in Alabama, and inland in Arkansas. Populations are now limited to Virginia, North Carolina, South Carolina, and Georgia. Smooth coneflower is a perennial herb with fleshy roots, hairless stems, and few leaves. It grows to 20.00 to 39.00 in (50.80 to 99.06 cm) in height, has a smooth stem, and few leaves. The simple leaves are smooth, with toothed edges, lance-shaped with rounded bases at the base of the stem, and smaller and elliptic at mid-stem. The leaves measure 4.00 to 8.00 in (10.16 to 20.32 cm) in length and 1.00 to 3:00 in (2.54 to 7.62 cm) in width. Flowers are light pink to purple, solitary, and 0.79 to 0.98 in (2.00 to 2.50 cm) across. Flowering occurs from May to July and fruiting occurs from June to October. Fruits are small, gray-brown, oblong, one-seeded, and usually four-angled. The smooth coneflower grows in meadows, open woodlands, glades, cedar barrens, roadsides, power line rights-of-way, clearcuts, and dry limestone bluffs. Plants usually grow in soil derived from North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 10 calcareous parent material. Optimal sites occur in areas with abundant sunlight and little competition from other herbaceous plants. Natural fires and large herbivores are important to the maintenance of the smooth coneflower habitat. BIOLOGICAL CONCLUSION: UNRESOLVED The open woodlands, roadsides, and clearcuts required by the smooth coneflower are present in the project area. A plant-by-plant survey was not conducted for this species nor were any observed during the March 11, 2002 site investigation. Additionally, a review of the NHP database on March 6, 2002 revealed no records of existing populations of the smooth coneflower within 1.00 mi (1.61 km) of the project area. An additional field survey will be conducted between May and July during the optimal survey window for the smooth coneflower. A letter will be attached as an addendum to this report after the completion of the survey for the smooth coneflower. Pleurobema collina (James spinymussel) Endangered Animal Family: Unionidae Date Listed: 1988 The James spinymussel is found in the James River basin, Virginia, and West Virginia. This mussel is usually found in a variety of substrates including sand, gravel, cobble, and mixed materials on the bottoms of streams and rivers. They generally require a slow to moderate current, and clean, well-oxygenated water. The James spinymussel lives in a variety of environments ranging from large rivers to shallow streams. The James spinymussel has an oblong shell approximately 2.00 in (5.08 cm) in size. This mussel is one of three freshwater mussels where prominent spines can be found on juvenile shells. The adults have a dark brown shell and the spines are typically absent or reduced. BIOLOGICAL CONCLUSION: UNRESOLVED The NCDOT will conduct a biological assessment to determine any potential impacts to this species due to construction of the proposed bridge. The NHP database of rare species and unique habitats reviewed on March 6, 2002 revealed no records of existing populations of the James spinymussel within 1.00 mi (1.61 km) of the project area. 4.2.2 Federal Species of Concern and State Listed Species Federal Species of Concern (FSC) are not afforded federal protection under the Endangered Species Act and are not subject to any of its provisions, including Section 7, until they are formally listed or proposed as threatened or endangered. However, the status of these species is subject to change, and therefore should be included for consideration. FSC are defined as a species that is under consideration for listing but for which there is insufficient information to support listing. In addition, organisms that are listed as Endangered (E), Threatened (T), or Special Concern (SC) by the NHP list of Rare Plant and Animal Species, are afforded state protection under the N.C. State Endangered Species Act and the N.C. Plant Protection and Conservation Act of 1979. North Carolina Department of Transportation TIP #: B-3696 March 2002 The LandMark Design Group, Inc. Project No. 1960024-M50.99 Page 11 There are two FSC listed by the FWS for Rockingham County. A survey for these species was not conducted during the site visit, nor were any of these species observed. A review of the NHP database of rare species and unique habitats on March 6, 2002 revealed no FSC within 1.00 mi (1.61 km) of the project area. Table 3.

BOX 25201, RALEIGH, N.C. 27611-5201 DAVID MCCOY GOVERNOR SECRETARY May 2, 2000 MEMORANDUM TO: Project File FROM: Karen T. Orthner Project Development Engineer SUBJECT: B-3696, Rockingham County, Replacement of Bridge No. 84 on SR 2579 over Jones Creek, State Project 8.2511001, F. A. Project BRZ-2579(1) A scoping meeting for the subject bridge was held in the Transportation Building on March 7, 2000. The following people were in attendance: Mike Cowan Division Seven Construction Derek Bradner Location and Surveys Unit Roy Girolami Structure Design Unit Jerome Nix Hydraulics Unit Lanette Ingham Programming and TIP Unit April Alperin State Historic Preservation Office Art McMillan Roadway Design Unit Gary Lovering Roadway Design Unit Heather Montague Project Development and Environmental Analysis Branch Karen Orthner Project Development and Environmental Analysis Branch The following comments were either given at the meeting or received previously: The Transportation Director for Rockingham County Schools stated that he could re-route buses during construction in the case of road closure. Steven Hales, EMS Coordinator for Rockingham County Schools, stated that road closure was not a problem as long as notification was given in ample time to re-route the EMS response efforts. Mike Cowan, Division Seven Construction Engineer, recommended closing the road and detouring traffic along surrounding roads during construction of the new bridge. 1*11 April Alperin of the State Historic Preservation Office (SHPO) recommended no architectural surveys in connection with this project. In addition, April recommended no archaeological surveys in the case of replacing the bridge in place with an off-site detour. Jerome Nix recommended that the bridge be replaced with a 70-foot long bridge in approximately the same location and roadway grade as the existing bridge. Sid Autry of Location and Surveys did not locate any utilities at the project site. David Cox of the Wildlife Resources Commission (WRC) commented that standard WRC comments apply to this project. Curtis Yates of the Bicycle and Pedestrian Division commented that this section of SR 2579 is not a part of a designated bicycle route nor is it listed in the TIP as needing incidental bicycle accommodations. Art McMillan and Gary Lovering of Roadway Design recommended replacing the bridge in approximately the same location as the existing bridge and detouring traffic along surrounding roads during construction. In addition, they noted that the roadway design could require a longer bridge with a slightly higher grade than that of the existing bridge. PROJECT INFORMATION Proiect Schedule: The Categorical Exclusion document from Project Development and Environmental Analysis is due January, 2001. The right-of-way acquisition date is scheduled for March, 2002 and the construction let date is scheduled for March, 2003. Existing Bridle Information: Bridge No. 84 was built in 1952. It is 53 feet long and 20 feet wide. The current weight limit for the bridge is posted 9 tons for single vehicles and 15 tons for truck transfer semi-trailers. The sufficiency rating for the bridge is 19.0 out of 100. Traffic Information: SR 2579 is classified as a Rural Minor Collector in the Functional Classification System. SR 2579 has a 55-mph posted speed limit in the project vicinity and a 40-mph cautionary speed limit across the bridge. The current average daily traffic (ADT) is 1200 vehicles per day (vpd) and the projected 2025 ADT is 2000 vpd. Approximately 2% of the ADT are dual trucks and I% of the ADT are truck transfer semi-trailers. Crash Data: No accidents were reported in the bridge vicinity from November 1996 until December 1999. DESCRIPTION OF ALTERNATES r_ During the alternate discussion, Gary Lovering of Roadway Design agreed to complete the preliminary cost estimates and roadway sketches by September, 2000. One alternate emerged from the scoping meeting for evaluation as follows: Alternate 1: Bridge No. 84 will be replaced with a 70-foot long bridge in approximately the same location as the existing bridge. Traffic will be detoured along surrounding roads during construction. New Cross Section: Due to some inconsistencies between the 1994 Greenbook and the Roadway Design Unit Design Manual, Roadway Design will be responsible for choosing the appropriate reference and indicating their choice in their cost estimate.
