The Gaston East-West Connector is designated as TIP Project No. U-3321 in the NCDOT's 2007-2013 Transportation ImprovementProgram (STIP). Figure 1 shows the general project location. The Project length is approximately 72 miles and the average corridor width is 1,400 feet. The corridor width is wider around potential interchange locations. The purpose of the proposed action is to improve east-west transportation mobility in the area around the City of Gastonia, between Gastonia and the Charlotte metropolitan area in general, and particularly to establish direct access between the rapidly growing area of southeast Gaston County and west Mecklenburg County. This project purpose is based on the following needs: � Need to improve mobility, access and connectivity within southern Gaston County and between southern Gaston County and Mecklenburg County. Need to reduce congestion and improve traffic flow on the sections of I-85, US 29-74 and US 321 in the project study area; improve high-speed, safe regional travel service along the US 29-74 intrastate corridor; and generally improve safety and reduce above average accident rates in the study area. 1.2 Project Alternatives There are sixteen new location Detailed Study Alternatives (DSA) under consideration far the proposed project. The corridor segxnents comprising these sixteen DSAs are shown in Table 1 and on Figure 2.

This report attempts to identify and estimate the probable consequences of the anticipated impacts to these resources. These descriptions are relevant only in the context of current design concepts. If design parameters and criteria change, additional field investigations will need to be conducted. 1.4 Methodology Published information and resources were collected priar to the field investigation. Information sources used to prepare this report include the following: • United States Geological Survey (USGS) 7.Y quadrangle map (Bessemer City 1973, Charlotte West 1968, Gastonia South 1973, Kings Mountain 1971). • NCDOT aerial photography of project study area. • North Carolina Nabxral Heritage Program Element Occurrence Data (October 200�. • Soil Survey of Gaston County (Soil Conservation Service, 1989). • Soil Survey of Mecklenburg County (Soil Conservation Service, 1980). • North Carolina Deparhnent of Environxnent and Natural Resources (NCDENR) Basinwide Assessment Report - Catawba River Basin - June 2003 (NCDENR 2003). • US Fish and Wildlife Service (USFWS) list of protected and candidate species (April 27, 2006). • US Fish and Wildlife Service (USFWS) National Wetlands Inventory mapping (Bessemer City, Charlotte West, Gastonia South, Kings Mountain). • North Carolina Wildlife Resources Commission (NCWRC) proposed Critical Habitat for aquatic species. Pebruary 2008 � Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Water resource inforxnation was obtained from publications posted on the World Wide Web by NCDENR Division of Water Quality (DW�. Information concerning the occurrence of federally protected species in the sbxdy area was obtained from the USFWS list of protected and candidate species (List updated May 10, 2007), posted on the World Wide Web by the Ecological Services branch of the USFWS office in North Carolina. Inforxnation concerning species under state protection was obtained from the NHP database of rare species and unique habitats. Files from the NHP were reviewed for documented sightings (August 27, 200'� of species on state or federal lists and locations of significant natural areas. Field surveys have been performed by a number of individuals beginning in 2005. These surveys include the following: • Surveys for threatened and endangered plant species were conducted in September and October 2005. The results of the survey are summarized in this report and detailed in the March 2006 Protected Plant Species Surveys report (PBS&J, 2006). A copy of this report is provided in Appendix A. • Surveys far the Carolina Heelsplitter (Lasmigona decorata) were conducted in September 2005 by NC Department of Transportation biologists. The results of the survey are summarized in this report and detailed in an October 2005 memorandum (NCDOT, 2005). A copy of this report is provided in Appendix A. • Wetland delineations and stream surveys were performed from October 2006 through March 2007 by biologists with Catena Group, J. A. Carter and Associates, and S&ME. The results of those surveys are presented in this report. Water resources were identified and their physical characteristics were recorded. Jurisdictional wetlands were delineated and evaluated based on criteria established in the U.S. Army Corps ofEngineers Wetlands Delineation Manual (Environxnental Laboratory 1987). Wetlands were classified based on Cowardin et al. (1979). • Field jurisdictional verifications for streams and wetlands were performed on April 12 and 13; May 2, 3, 10 and 11; and June 25 and 26, 2007. Mr. Steve Lund was the USACE representative and Ms. Polly Lespinasse was the NCDWQ representative that perforxned the field verifications. No written confirxnation or verification has been issued by the US Arxny Corps of Engineers. Written verification was received from DWQ by letter dated August 2, 2007. • A general field survey was conducted by Earth Tech biologists from October 16, 2006 to November 8, 2006. • Surveys for bald eagle nests were performed by Earth Tech biologists. Aerial surveys were first perforxned on December 19, 2006. Nests observed during the aerial survey were field-checked from the ground on February 8, 2007. A copy of a memo describing this survey is provided in Appendix A. For the purposes of this study, a brief habitat assessment was performed within the project study area. Plant communities and their associated wildlife were identified using a variety of observation techniques, including active searching, visual observations, and identifying characteristic signs of wildlife (sounds, tracks, scats, and burrows). Terrestrial community classifications generally follow Schafale and Weakley (1990), where appropriate. Plant nomenclabxre follows the National Plant Data Center PLANTS Database (USDA, NRCS 200�. Vertebrate names follow Rohde et al. (1994), Conant et al. (1998), the American Ornithologists' Union (2001), Thorpe and Covich (1991), and Webster et al. (1985). Vegetative communities were mapped using aerial photography of the project site. Predictions regarding wildlife community composition involved general qualitative habitat assessment based on existing Pebruary 2008 3 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina vegetative communities.

A listing of Individuals involved with the various investigations and their qualifications is provided as Appendix B. The Principle Investigators that prepared this report are as follows: Investigator: Ron Johnson Education: M.S., Biological Sciences, Illinois State University Experience: Biologist, Earth Tech 20 years Expertise: Nabxral resources surveys, wetland and stream mitigation Investigator: Kevin Lapp Education: M.S., Biology, Appalachian State University Experience: Biologist, Earth Tech 2 years Expertise: Conservation and Natural Resources Management Investigator: Rachael Thorn Education: B.S., Earth Science, University of North Carolina at Asheville Experience: Biologist, Earth Tech 2 years Expertise: Stream channel restoration, groundwater and soil sampling 1.6 Terminology and Definitions For the purposes of this report, the following terms are used for describing the limits of natural resources investigations. `Project study area" denotes the area within the study corridors and includes the 16 alternatives. The study corridor is braided in most places and the average width is approximately 1,400 feet (426 m). The sbxdy corridors are expanded at potential interchange areas (Figure 1). The "project vicinity" is an area extending 0.5 mile (0.8 kxn) on all sides of the project study area, and "project region" is an area equivalent in size to the area represented by a 7.5-minute USGS quadrangle map (about 61.8 square miles) with the project study area occupying the central position. 2.0 PHYSICAL RESOURCES The project study area is in south-central North Carolina within the Piedmont physiographic province in the Catawba River drainage basin. The topography of the project vicinity is nearly level in the vicinity of stream floodplains to moderately steep and rolling. Elevations in the project sbxdy area range from approximately 550 to 900 feet (168 to 274 m) (United States Geological Survey). Pebruary 2008 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina The proposed project study area is a mixture of urban, suburban, and rural areas. Areas around the outskirts of Belmont and Gastonia are relatively rural and characterized by low density residential and agricultural areas. Areas in or adjacent to the city limits of Belmont and Gastonia are characterized by moderate to high density residential areas or small businesses. 2.1 Soils Information about soils in the project study area was taken from the Soil Survey of Gaston County, North Carolina (USDA 1989) and Soil Survey ofMecklenburg County, North Carolina (USDA 1980). 2.L1 SoilAssociations Soil associations are groupings of soils with similar geology and landscape occurrence across the region. Broad soil management practices can be applied within each association. The inclusion of dissimilar soils is somewhat limited, usually to specific landscape features. Most of these soils are in use as pasture, row crops, woodland, or urban use. The following soil associations occur within the projectsbxdy area. CeciL This association occurs throughout Mecklenburg County and occurs on gently to strongly sloping landscapes. It has soils that are well drained and have a clay loam surface and predominately clayey subsoil. Cecil-Pacolet. This association is primarily in the central and narthwestern parts of Gaston County and southwestern parts of Mecklenburg County. It occurs on gently sloping to steep landscapes that are well drained. The soils have a loamy surface layer and predominately clayey subsoil. Cecil-Urban land. This association is in the commercial, industrial, and residential areas of Gastonia and other communities. It occurs on gently sloping to strongly sloping landscapes that are well drained or contain impervious urban land. The soils have a loamy surface layer and predominately clayey subsoil. Gaston-Winnsboro-CeciL These soils are mainly in the eastern part of Gaston County and occur on gently sloping to moderately steep landscapes. These are well drained soils that have a loamy surface layer and predominately clayey subsoil. Tatum. This association occurs on gently sloping to moderately well drained areas mainly in the southwestern to west central part of Gaston County. These soils are well drained and have a gravelly loamy surface layer and predominately clayey subsoil. Appling-Wedowee-Pacolet. This association occurs on gently sloping to steep landscapes mainly in the eastern part of Gaston County. These soils are well drained and have a loamy surface layer and predominately clay subsoil. Madison. This soil group is found on gently sloping to moderately steep landscapes. These soils are well drained and have a loamy surface layer and predominately clayey subsoil. Chewacla-Congaree. This association is found on floodplains along major streams. It has soils on nearly level landscapes that are somewhat poorly drained with a loamy, sandy loam or clay Pebruary 2008 5 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina loam underlying material. The Chewacla soils are found in low lying areas away from the larger stream channels. The Congaree soils are well drained or moderately well drained and are found in slightly higher places near the larger stream channels. Congaree soils have a loam surface layer and a sandy to silty clay loam underlying layer. 2.1.2 Soil Map Units The soil map unit offers greater detail of soil within the project study area. They also show the range of soils within the association. Due to heterogeneous nature of soils, each map unit approximates the general features found. Small inclusions of dissimilar soils still occur because of the level of mapping. The map unit details provide adequate inforxnation to list specific management concerns that can be expected. Because of the size of the project a number of individual map units can be found in the project study area.

Numerous streams were identified in the project study area and are shown on Figure 3a-3w. 2.2.1 Physical Characteristics of Surface Waters The project is located in the Catawba River basin (US Geologic Survey Hydrologic Unit Codes 03050101, 03050102, 03050103, DWQ subbasins 03-08-34, 03-08-36, 03-08-3'�. The area has rolling topography dissected by wide floodplains along larger streams. The named streams within the project study area are typically larger channels. Twelve named streams (on either USGS topographic maps or NCDWQ hydrology data) occur in the project study area. One of these occurs in Mecklenburg County (Beaverdam Creek) and ten other named streams occur in Gaston County. The last, the Catawba River/Lake Wylie, divides the two counties (Table 3). Table 3.

Information concerning these streams is presented in Appendix C. 2.2.2 Best Usage Classification Surface waters in North Carolina are assigned a classification by the DWQ that is designed to maintain, protect, and enhance water quality within the state (NCDENR 2006a). The majority (10 of 12) of the named streams in the project study area are classified as C. Class C waters are protected for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner. There are no restrictions on watershed development activities. These waters are suitable for all Class C uses. If a stream is not classified it assumes the classification of its receiving stream. Therefore, the small unnamed tributaries that flow into these streams carry the same classification. The other two named water bodies, the Catawba River/Lake Wylie and the South Fark Catawba River, carry surface water designations indicating uses as drinking water sources. The Catawba River/Lake Wylie [Index # 11-(123.5)] is designated as WS-V, B and South Fark Catawba River [Index # 11-129- (15.5)] is designated as WS-V. WS-V waters are protected as water supplies which are generally upstream of WS-IV waters (water protected as water supplies which are generally in moderately to highly developed watersheds). No categorical restrictions on watershed development or treated wastewater discharges shall be required, however, the Commission or its designee may apply appropriate management requirements as deemed necessary for the protection of downstream receiving waters. The B designation indicates freshwaters protected for primary recreation which includes swimming on a frequent or organized basis and all Class C uses. No waters classified as High Quality Water (HQ�, Water Supplies (WS-I or WS-I� or Outstanding Resource Waters (OR� occur within 1.0 miles (1.6 kxn) of the project sbxdy area. 2.2.3 Water Quality This section describes the quality of the water resources within the project sbxdy area. Potential impacts to water quality from point and non-point sources are evaluated. Water quality assessments are based upon published resource information and field study observations. 2.2.3.1 General Watershed Characteristics The project is located in a watershed with a wide variety of land uses. Some large tracts are still forested or in agriculbxral production (largely hay). A large proportion of the watershed is moderately developed as residential or industrial. Many of the waterways and wetlands within Pebruary 2008 10 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina the watershed remain forested although some of the streams have minimal riparian buffers at best. This is most common in the suburban, urban, and industrial areas. Potential threats to water quality in this area are agricultural practices, development, and land clearing which may contribute to soil erosion and increases in chemical runoff and nutrient input. 2.2.3.2 Basin-wide Assessment Report Basin-wide water quality assessments are conducted by the Environxnental Sciences Branch, Water Quality Section of the DWQ. The program has established monitoring stations for sampling selected benthic macroinvertebrates and fish, which are known to have varying levels of tolerance to water pollution. An index of water quality can be derived from the number of taxa present and the ratio of tolerant to intolerant taxa. Streams can then be given a bioclassification ranging from Poar to Excellent. The project runs through 3 basins in the Catawba River basin: 30834, 30836, and 30837. Sampling in subbasin 30834 is limited to a sample location on Lake Wylie in Yark County, South Carolina. This reservoir was monitored in 2001 and 2002 and was classified as eutrophic. Percent oxygen saturation at the surface exceeded the water quality standard for dissolved gases (NCDENR, 2003). Two fish community monitoring sites and one benthic macroinvertebrate monitoring site were sampled from Catawba River Subbasin 30837 in 2002. The benthic macroinvertebrate monitoring site is located on SC 564 where it crosses Crowders Creek. It received a Fair rating both in 1997 and 2002. This stream formerly had problems associated with effluent from a chicken processing plant and Bessemer City, both of which have now ceased. Although the bioclassification rating remained the same from 1997 to 2002, several metrics improved. The fish community sampling station on Crowder's Creek is located at SR 1108 and received a Fair rating in both 1997 and 2002. More species and fish were collected in 2002 than in 1997 but there was a decline in the diversities of suckers and sunfish and an absence of piscivores. Only one specimen of a darter and an intolerant species were present in 2002. There are seven National Pollutant Discharge Elimination System (NPDES) perxnitted dischargers within the site's watershed with a combined discharge of 1.02 MGD (NCDENR, 2003). A fish sampling site on Catawba Creek rated good-Fair in 1997 but dropped to Fair in 2002. Three small NPDES perxnitted dischargers operate within the watershed and the stream and riparian zone are degraded by poor land use and livestock access to the stream. As in Crowders Creek, there were more fish collected in 2002 but the community shifted towards one with a greater percentage of herbivores and omnivores. Intolerant species were absent in both 1997 and 2002 (NCDENR, 2003). 2.2.3.3Impaired Waters The North Carolina GVater Quality Assessment and Impaired Waters List (NCDENR 2006b) is an integrated report that includes both the 305(b) and 303(d) reparts. The 305(b) report is compiled biennially to update the assessment of water quality in North Carolina and to meet the Section 305(b) reporting requirement of the Clean Water Act. In general, 305(b) reports have described the quality of surface waters, groundwaters, and wetlands, and existing programs to protect water quality. The 305(b) reparts present how well waters support designated uses (e.g., swimming, aquatic life support, water supply), as well as likely causes (e.g., sediment, nutrients) and potential sources of impairment. The 303(d) list is a comprehensive public accounting of all Pebruary 2008 11 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina impaired waterbodies that is derived from the 305(b) report/Use Suppart An impaired waterbody is one that is damaged by pollutants, such as nitrogen, phosphorus, and fecal coliform bacteria, and by pollution such as hydromodification and habitat degradation. The source of impairment might be from point sources, non-point sources, and atmospheric deposition. The standards violation might be due to an individual pollutant, multiple pollutants, or an unknown cause of impairment. This list is compiled by the DWQ and submitted to the Environxnental Protection Agency (EPA) by April 1 of every even year. Within the project study area three of the water resources described in Section 2.2.1 are designated as biologically impaired water bodies regulated under the Final 2006 provisions of the Clean Water Act (CWA) 303(d). Abernethy Creek, Catawba Creek, and Crowders Creek, are listed on the Final 2006 303(d) list as having impaired biological integrity (NCDENR 2006b). The potential source of impairxnent for all of these streams is urban runoff and storm sewers. There are no additional streams within 1 mile of the project study area listed on the 303(d) list Two additional water resources, Blackwood Creek and Catawba River/Lake Wylie, are listed in the 305(b) integrated report but do not occur on the 303(d) list These are waters that are not supporting one or more of their designated use, but may not be sufficiently degraded to occur on the 303(d) list. 2.2.3.4 PointSourceDischargePermits Point source discharges in North Carolina are regulated through the NPDES program administered by the DWQ. All dischargers are required to obtain a permit to discharge. As of July 30, 2007 (NCDENR 2007), there are 35 perxnitted discharges into streams in the project study area. They are listed in Table 4 below. Table 4.

As rainfall or snowmelt runoff moves over the earth's surface, natural and man-made pollutants are picked up, carried, and ultimately deposited into lakes, rivers, wetlands, coastal waters, and groundwater. Non-point source pollution includes fertilizers, herbicides, and insecticides from farms and residential areas; hydrocarbons and chemicals from urban runoff; sediments from construction sites, land clearing, and eroding stream banks; bacteria and nutrients from livestock, animal wastes, and faulty septic systems; and atmospheric deposition. The effects of NPS pollutants on water resources vary, and in many instances, may not be known. These pollutants generally have harxnful effects on drinking water supplies, recreation, wildlife, and fisheries. Earth Tech biologists conducted a general visual observation of potential NPS discharges located within and near the project study area. Atxnospheric deposition from passing vehicles; fertilizers, herbicides, and insecticides from nearby agricultural and residential areas; and hydrocarbon and chemical runoff from nearby roadways and residential driveways were identified as potential sources of NPS pollution near the project study area. Overall, the threat of non-point source discharge is above average because of the high density of impervious surfaces found near streams within the project study area. 2.2.3.6 National Marine Fisheries Service Essential Fish Habitat The 1996 Congressional amendments to the Magnuson-Stevens Fishery Conservation and Management Act (MSFCMA) set forth new requirements far the National Marine Fisheries Service (NIVIFS), regional fishery management councils (FMC), and other Federal agencies to identify and protect impartant marine and anadromous fish habitat. These amendments established procedures far the identification of Essential Fish Habitat (EFI� and a requirement for interagency coordination to further the conservation of federally managed fisheries. Gaston and Mecklenburg Counties are not in Essential Fish Habitat identified counties and do not border the ocean or estuarine waters. Neither the Catawba River nor any of its tributaries are considered esbxarine waters; therefore; there will be no EFH impacts associated with this project. 2.2.4 Summary ofAnticipated Impacts 14 Pebruary 2008 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Both temporary and permanent impacts to the water quality of the project sbxdy area will occur from the project Potential short-terxn impacts to water resources in the project study area will include increased sedimentation and turbidity from construction-related erosion. To help mitigate potential temporary impacts, Best Management Practices (BMP) for sedimentation and erosion control should be implemented during construction activities. Project construction may result in the following impacts to surface water resources: • Increased sediment loading and siltation as a consequence of watershed vegetation removal, erosion, and/or construction. • Decreased light penetration/water clarity from increased sedimentation. • Changes in water temperature with vegetation removal. • Changes in the amount of available organic matter with vegetation removal. • Increased concentration of toxic compounds from highway runoff, construction activities and construction equipment, and spills from construction equipment • Alteration of water levels and flows as a result of interruptions and/or additions to surface and groundwater flow from construction. Non-point source discharges from the highway surface can be partially mitigated by the construction of filter strips of vegetation adjacent to the highway. Best Management Practices (BMPs) during construction may include strict erosion and sediment control procedures, careful containxnent of oil, gasoline, and other hazardous materials, and reduced canopy removal within riparian fringes along the streams. Construction impacts may not be restricted to the communities in which the construction activity occurs but may also affect downstream communities. Efforts will be made to ensure that no sediment leaves the construction site. NCDOT's Best Management Practices for the Protection of Surface Waters will be implemented, as applicable, during the construction phase of the project to ensure that no sediment leaves the construction site. 3.0 BIOTIC RESOURCES Terrestrial and aquatic communities are included in the description of biotic resources. Living systems described in the following sections include communities of associated plants and animals. These descriptions refer to the dominant flora and fauna in each community and the relationships of these biotic components. Descriptions of the terrestrial systems are presented in the context of plant community classifications. These classifications follow Schafale and Weakley (1990) where possible. They are also cross-referenced to The Nature Conservancy International Classification of Ecological Communities (ICEC): Terrestrial Vegetation of the Southeastern United States (Weakley et al., 1998) (NatureServe 200�, which has been adopted as the standard land cover classification by the Federal Geographic Data Committee. Representative animal species that are likely to occur in these habitats (based on published range distributions) are also cited. Scientific nomenclabxre and common names (when applicable) are used for the plant and animal species described. Subsequent references to the same species are by the common name only. Fauna observed during field investigations are denoted with an asterisk �*)� 3.1 Terrestrial Communities 15 Pebruary 2008 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Nine terrestrial communities were identified within the project study area; agricultural, clearcut, hardwood forest, Mesic Mixed Hardwood Forest, mixed pine-hardwood forest, pine forest, pine plantation, successional, and disturbed, (Figure 4A-44�. Dominant faunal components associated with these terrestrial areas will be discussed following the community description. Many species are adapted to the entire range of habitats found along the project alignxnent but may not be mentioned separately for each community. 3.L1 Disturbed Community The majority of the terrestrial communities found in the project sbxdy area are this type of community. This community type includes four types of habitat that have recently been or are currently impacted by human disturbance including regularly maintained roadside shoulder, mining, commercial development, and residential areas. A few areas that have been recently clear-cut are included in this disturbed community. These habitats are kept in a low-growing, early successional state by regular maintenance (except clear-cuts). The regularly maintained roadside shoulder is mowed frequently and is dominated by herbaceous vegetation. The dominant species include broom sedge (Andropogon virginicus), fescue (Festuca sp.), Japanese honeysuckle (Lonicera japonica) and various annual and perennial herbaceous weed species. A representative example of this community type is located south of Exit 13 on I-85 in a subdivision along Bright Avenue (Figure 4A). The commercial and residential area includes maintained lawns and waste places near outbuildings and parking areas. Most of these areas are maintained on a regular basis by either mowing or herbicide application. Residential areas are dominated by various turf grasses, ornamental shrubs, and large shade trees including red maple (Acer rubrum), northern red oak (Quercus rubra) and southern red oak (Quercus falcata). Commercial areas can resemble residential areas if fastidiously maintained or may develop into an early successional habitat if left fallow. 3.1.2 Agriwltural Land This community is not a nabxral community but one that is planted and/or maintained by humans for the purpose of growing food crops or livestock. The most common crop encountered in the project study area include pasture grasses for the purpose of growing hay. Cattle and horses were also being raised in a few locations in the project study area. These pasturelands were composed of grasses as well as annual and perennial herbaceous species. A representative concentration of this community type is located north of Exit 13 on I-85 and consists of a large netwark of pasbxres (Figure 4A). 3.1.3 Clearwt This community is an artificially created community as a result of a recent timber harvest Typically clearcuts are composed of early regenerating trees and shrubs, large amounts of leftover downed woody debris, and numerous colonizing herbaceous species. Common herbaceous species in clearcuts include pokeberry (Phytolacca americana), fireweed (Erechtites hieracifolia), broomsedge, and asters. Many tree and shrub seedlings begin to sprout following a clearing and common species include red maple, sweetgum (Liquidambar styraciflua), tulip poplar (Liriodendron tulipifera), shortleaf pine (Pinus echinata), and loblolly pine (Pinus taeda). A representative example of this community type is located east of Homewood Drive and South of Linwood Road SR 1133 (Figure 4D). Pebruary 2008 16 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina 3.1.4 Hardwood Forest The hardwood forest is dominated by a mixture of oaks, tulip poplar, sweetgum and red maple. This community is found throughout the project study area and consists mostly of mature forests. Forests described as hardwood forests in the project study area are most similar to those described by Schafale and Weakley as Dry Mesic Mixed Oak Hickory Forest (Natureserve community Piedmont Dry Mesic Oak Hickory Forest CEGL008475) ar Mesic Mixed Hardwood Forest (Nabxreserve community Piedmont Acidic Mesic Mixed Hardwood Forest CEGL008465) in upland areas and piedmonUmountain bottomland forest in floodplains that are adjacent to larger stream channels. The piedmonUmountain bottomland forest did not match a community type as described by Natureserve. Species currently found in the canopy include northern red oak, southern red oak, sweetgum, and red maple. Because of past disturbance, an occasional Virginia pine (Pinus virginiana) or shortleaf pine is often found scattered within this community. Understory species include red maple, flowering dogwood (Cornus florida), and American holly (Ilex opaca). Shrubs include blueberries (i�accinium sp.) and strawberry bush (Euonymus americana). Herbaceous vegetation is usually sparse although it can be locally diverse and includes crane-fly orchid (Tipularia discolor), spotted wintergreen (Chimaphila maculatum), and ebony spleenwort (Asplenium platyneuron). Exotics can be problematic in these communities with Chinese privet (Ligustrum sinense), multiflora rose (Rosa multiflora), autumn olive (Eleagnus sp.) and Japanese honeysuckle (Lonicera japonica) being the most common species encountered. Large examples of this community type are located on either side of Lewis Road SR 1126 (Figure 4G). 3.L5 Mesic Mixed Hardwood Forest (Piedmont Subtype) This community is uncommon in the project study area and is distinguished from the previously described hardwood forest in that it is relatively mature and closely matches the community type as described by Schafale and Weakley (1990). This mature forested community occurs in mesic areas on lower slopes, steep north facing slopes, and ravines on acidic soils. The canopy is dominated by mesophytic species such as American beech (Fagus grandifolia), yellow poplar, red maple, and red oak (Quercus rubra). Understory species include flowering dogwood, American holly and red maple. The shrub and herb layer ranges from sparse to fairly dense. Common shrub species include strawberry bush and blueberries. Typical herbs include Christmas fern (Polystichum acrostichoides), wild ginger (Hexastylis arifolia), and lion's foot (Prenanthes serpentaria). One of the few examples of this community is located along Chapel Grove Road SR 1131 (Figure 4E). This community was described by Schafale and Weakley (1990) and the Nabxreserve equivalent of this forest is most likely a Piedmont Acidic Mesic Mixed Hardwood Forest (CEGL008465). 3.1.6 Mixed Pine-Hardwood Forest The mixed pine-hardwood forest is found in both upland and wetland communities having hardwoods with a larger component of pines than the previously described hardwood forest approaching an even mixture of pines and hardwoods. This community is typically found on upland areas throughout the project study area. These communities usually contain younger trees and past disturbances have created the mixture of tree species. Typical canopy species include Pebruary 2008 17 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina tulip poplar, sweetgum, red maple and the oaks found in the upland hardwood forest (Section 3.1.4) with an important component of pine as well. These pines include Virginia pine, shartleaf pine, and occasionally loblolly pine. Understory trees found in this community include red maple, flowering dogwood, and American holly. Shrubs are often dense and species include strawberry bush, blueberry. Vines are usually a strong component of these communities and include muscadine grape (Vitis rotundifolia) and cat greenbrier (Smilax rotundifolia). Herbaceous vegetation is usually sparse and exotic vegetation is often present in highly disturbed examples of this community and includes Japanese honeysuckle, Chinese privet, autumn olive, and multiflora rose. A comparable community type is not described by Schafale and Weakley (1990) due to this community's large degree of manipulation. Some less disturbed examples of this community resemble a Dry-Mesic-Oak Hickory Forest with a considerable pine influx. The less disturbed examples of this community type are most similar to the Piedmont Dry Mesic Oak Hickory Forest (CEGL008475) community type as described by Nabxreserve. A representative example of this community type is located between Double Oaks Road and Dorchester Road SR 3076 (Figure 41V�. 3.1.7 Pine Forest Scattered throughout the project are pine forests that appear associated with abandoned agricultural land, unxnanaged clearcuts, and unxnaintained pine plantations. This community is differentiated from pine plantations in that they are not heavily managed far timber production. These pine forests are typically young, closed canopy forests containing primarily Virginia pine, shortleaf pine, or loblolly pine. Pine forests typically have a canopy that is dominated by pine species with only a negligible component of hardwoods in the canopy as compared to mixed pine-hardwood forest that has a relatively even mixture of pines and hardwoods in the canopy. In younger stands the understory may be dense but becomes more open in older stands. Other early successional trees such as red maple, sweetgum, and tulip poplar may also be present either in the understory or scattered in the canopy. A comparable community type is not described by Schafale and Weakley (1990) due to these communities' large degree of manipulation. This community type also did not match a community type as described by Natureserve but some stands resemble the Virginia Pine Forest Alliance as described by Natureserve. A representative example of this community type is located north of Bayshore Drive SR 3018 (Figure 4R). 3.1.8 Pine Plantation This community is an artificial community that consists of planted pine stands that are managed for timber production. These vary in age depending on the stage of production and range from young stands with the canopy beginning to close to mabxre stands ready for harvest The most commonly encountered species in plantations were loblolly pine and shortleaf pine. These stands varied from an open to densely stocked nature depending on the degree and stage of management. A comparable community type is not described by Schafale and Weakley (1990) due to these communities' large degree of manipulation. This community type also did not match a community type as described by Natureserve. A representative example of this community type is located west of the intersection of Worrells River Road and NC 279 (Figure 4R). Pebruary 2008 18 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina 3.1.9 Successional Community The successional community includes those communities that follow a natural or artificial disturbance and are in an early successional state. This community, like the clearcut, is composed of colonizing species and is characterized by a lack of a tree canopy. These communities develop into a variety of communities when in a mature state but are difficult to assign to a described natural community when in an early successional state. Species commonly found in successional communities are blackberries (Rubus sp.), pokeberry, broomsedge, sweetgum, red maple, shortleaf pine, Virginia pine, muscadine grape, and silverling (Baccharis halimifolia). A dense group of this community type is located southwest of Exit 13 on I-85 along a powerline right-of- way (Figure 4A). 3.L10 Faunal Component Species that prefer open areas for feeding and nesting can be found in the successional, clearcut, and disturbed communities. The animal species present in these habitats are opporbxnistic and capable of surviving on a variety of resources, ranging from vegetation to both living and dead faunal components. Fauna ar tracks observed in the field are indicated with an asterisk. The European starling (Sturnus vulgaris), northern mockingbird* (Mimus polyglottos), and field sparrow (Spizella pusilla) are common birds that use these habitats to find insects, seeds, or worms. The American crow* (Corvus brachyrhynchos), mourning dove* (Zenaida macroura), American robin* (Turdus migratorius), raccoon* (Procyon lotor), and the Virginia opossum (Didelphis virginiana) are true opporbxnists and will eat virtually any edible items including vegetation, fruits, seeds, insects, and carrion. Large open expanses are often used by raptors such as the red-shouldered hawk (Buteo lineatus) and scavengers such as the bxrkey vulture (Cathartes aura). Many species are highly adaptive and may utilize the edges of forests and clearings or prefer a mixture of habitat types. The eastern cottontail (Sylvilagus floridanus) and raccoon* prefer a mix of herbaceous and woody vegetation and may be found in the dense shrub vegetation, along roadsides, and in residential areas. White-tailed deer* (Odocoileus virginianus) will utilize the forested areas as well as the adjacent open areas. The black rat snake* (Elaphe obsoleta obsoleta) will utilize forested habitat and open areas to forage for rodents. Blue jays (Cyanocitta cristata), narthern bobwhite (Colinus virginianus), eastern towhee (Pipilo erythrophthalmus), song sparrows (Melospiza melodia), Carolina chickadees (Poecile carolinensis), white-throated sparrows (Zonotrichia albicollis), and bluebirds (Sialia sialis) are likely species that occur in the project sbxdy area and utilize edge habitat Five-lined skinks (Eumeces fasciatus) and black racers (Coluber constrictor) are common reptile species that utilize a mixture of habitat types. Mature pine, hardwood, and mixed forest habitats are important habitat for many species. Neotropical migratory birds, in particular, are extremely dependent on these areas. Species such as pileated woodpecker (Dryocopus pileatus) and barred owls (Strzx varia) prefer forested riparian areas while neotropical migrant species such as the ovenbird (Seiurus aurocapillus), wood thrush (Hylocichla mustelina), and Acadian flycatcher (Empidoncix virescens) prefer the upland woods. In the leaf litter of the forested habitats, the southern short-tailed shrew (Blarina carolinensis) and the white-footed mouse (Peromyscus leucopus) may be found. Gray squirrels* (Sciurus carolinensis) are often observed in wooded areas. The spring peeper (Pseudacris crucifer) can be found under forest litter and in brushy undergrowth. The eastern box turtle (Terrapene carolina) is a terrestrial turtle but will be found near streams in hot, dry weather. The ground skink (Scincella lateralis) may also be found in forested communities. Forested wetlands Pebruary 2008 19 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina are especially appealing to great blue herons* (Ardea herodias), mud salamanders (Pseudotriton montanus), southern cricket frogs (Acris gryllus), and green frogs (Rana clamitans melanota). 3.2 Aquatic Communities A variety of flowing and stillwater habitats occur in the project study area. Within the project study area the streams range from small interxnittent channels to large perennial streams and stillwater habitats range from small farm ponds to Lake Wylie, a large water supply reservoir. This allows for a variety of aquatic communities to be present throughout the project sbxdy area. The smaller stream channels are first- or second-order tributaries and bed material typically consists of sand, gravel, and cobble. On the more impacted channels, sand and sediments are common. Most of the streams are clear to moderately turbid. Riparian buffers along these streams varied from being almost nonexistent along some smaller more urban streams to extensive forested buffers along streams in more remote rural locations. Incision has constricted or eliminated the overbank flow of many of the smaller streams resulting in channel depths that can approach 4 feet or more. All streams in the sbxdy area are designated as warmwater habitats by the NC Division of Water Quality (NCEEP, 200'�. Based on range maps in Menhinick (1991) it can be presumed that the following fish species occur in project study area streams; redbreast sunfish (Lepomis auritus), bluegill* (Lepomis macrochirus), largemouth bass (Micropterus salmoides), rosyside dace*(Clinostomus funduloides), eastern mosquitofish (Gambusia holbrooki), bluehead chub (Nocomis leptocephalus), greenfin shiner (Notropis analostanus), spottail shiner (Notropis hudsonius), brown bullhead (Ictalurus nebulosus), and tessellated darter (Etheostoma olmstedi). Streams also support a diverse assemblage of invertebrate life and semi-aquatic vertebrates. Common types of adult and larval invertebrates encountered include snails* (Physidae), crayfish* (Decapoda), stoneflies (Plecoptera), mayflies* (Ephemeroptera), caddisflies* (Trichoptera), water pennies* (Coleoptera), dobsonfly* (Corydalidae), scud* (Amphipoda), dragonflies* (Anisoptera), and damselflies* (Zugoptera). Semi-aquatic amphibians typically associated with streams include southern two-lined salamanders* (Eurycea cirrigera), dusky salamander* (Desmognathus fuscus), and green frogs* (Rana clamitans). Asiatic clams* (Corbicula fluminea) were a very common exotic mollusk species in project streams. Additionally numerous farxn ponds and a large reservoir occur in the project study area. Usually farm ponds are stocked with a low diversity of game species. Typical species found in farm ponds include largemouth bass, bluegill, channel catfish (Ictalurus punctatus), and mosquitofish (Gambusia holbrooki). Lake Wylie is a large reservoir that supports a thriving recreational fishery. Popular target species found in the lake include largemouth bass, bluegill, black crappie (Poxomis nigromaculatus), white crappie (Poxomis annularis), white perch (Morone americana), blue catfish (Ictalurus furcatus), and channel catFish . 3.3 Summary ofAnticipated Impacts Project construction will have various impacts to the previously described terrestrial and aquatic communities. Any conshuction activities in or near these resources have the potential to impact biological functions. This section quantifies and qualifies potential impacts to the nabxral communities within the project sbxdy area in terxns of the area impacted and the plants and animals affected. Temporary and permanent impacts are considered here along with recommendations to minimize or eliminate impacts. Pebruary 2008 20 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina 3.3.1 Terrestrial Communities Both direct and indirect impacts will occur to the terrestrial communities and the animals that inhabit them. Terrestrial communities in the project sbxdy area will be impacted permanently by project construction from clearing and paving. Table 5 provides the acreage of terrestrial communities by habitat type that will be impacted by each alternative. These impacts are calculated based upon preliminary design as of January 1, 2007 and is the area contained within the proposed right-of-way. Table 5.

Animal species will be displaced into surrounding communities. Adult birds, mammals, and some reptiles are mobile enough to avoid mortality during construction. Young animals and less mobile species, such as many amphibians, may suffer direct loss during construction. The plants and animals that are found in the upland communities are generally common throughout central North Carolina. Impacts to terrestrial communities, particularly in locations having steep to moderate slopes, can result in the aquatic community receiving heavy sediment loads as a consequence of erosion. Construction impacts may not be restricted to the communities in which the construction activity occurs but may also affect downstream communities. Effarts should be made to ensure that no sediment leaves the construction site. Indirect impacts will occur from forest fragxnentation. Forest fragxnentation occurs when large, contiguous forests are divided into smaller patches by urbanization, roads, and agriculture. This process reduces the foresYs function as a habitat for many plant and animal species and has been shown to reduce biodiversity by altering the amount of forest interior habitat reducing the amount of habitat available for species requiring large uninterrupted tracts. Pebruary 2008 21 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina When habitat is fragmented, the amount of edge habitat increases at the expense of interior habitat Species dependant upon interior habitat suffer (such as many migratory or neo-tropical birds), while edge dependant species including invasive species and predators thrive. Highly fragxnented forests cannot provide the food, cover, or reproduction needs of interior forest species. The road itself can also provide a physical barrier to the movement of mammals, reptiles, and amphibians along wildlife corridors and from one forest patch to another. 3.3.2 Aquatic Communities Impacts to aquatic communities include fluctuations in water temperabxre as a result of the loss of riparian vegetation. Shelter and food resources, both in the aquatic and terrestrial portions of these organisms' life cycles, will be affected by losses in the terrestrial communities. The loss of aquatic plants and animals will affect terrestrial fauna that rely on them as a food source. Temporary and permanent impacts to aquatic organisms may result from increased sedimentation. Aquatic invertebrates may drift downstream during construction and recolonize the disturbed area once it has been stabilized. Sediments have the potential to affect fish and other aquatic life in several ways including the clogging and abrading of gills and other respiratory surfaces, affecting the habitat by scouring and filling of pools and riffles, altering water chemistry, and smothering different life stages. Increased sedimentation may cause decreased light penetration through an increase in turbidity. Wet concrete should not come into contact with surface water during bridge construction as it can adversely affect aquatic life. Potential adverse effects can be minimized through the implementation of NCDOT BestManagement Practices for Protection of Surface Waters. 4.0 JLTRISDICTIONAL TOPICS This section provides inventories and impact analyses for two federal and state regulatory issues: "Waters of the United States" and federally protected species. 4.1 Waters of the United States Wetlands and surface waters fall under the broad category of "Waters of the United States" as defined in 33 CFR § 328.3 and in accordance with provisions of Section 404 of the CWA (33 U.S.C. 1344). These waters are regulated by the U.S. Arxny Corps of Engineers (USACE). Any action that proposes to dredge or place fill material into surface waters or wetlands falls under these provisions. 4.L1 Characteristics of Wetlands and Surface Waters Jurisdictional wetlands were identified within the project study area (Figure 3a-3w). Many of the wetlands are small headwater systems associated with the numerous tributaries. Larger bottomland hardwood wetland systems are associated with some of the larger streams and Lake Wylie. Field jurisdictional verifications for streams and wetlands were performed on April 12 and 13; May 2, 3, 10 and 11; and June 25 and 26, 2007. Mr. Steve Lund was the USACE representative and Ms. Polly Lespinasse was the NCDWQ representative that perforxned the field verifications. No written confirmation or verification has been issued by the US Army Corps of Pebruary 2008 22 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Engineers. The DWQ issued a letter on August 2, 2007 indicating that the DWQ will consider all sites identified in the revised jurisdictional verification package (dated 7/25/0'� as accurate. Appendix D contains USACE Wetland Determination forms for each wetland and Appendix E contains the DWQ rating form. Wetlands were also assigned a quality rating of Low, Medium, or High. In general wetlands that received a score of 0 to 40 were considered Low Quality. Wetlands with scores ranging from 40 to 64 were rated Medium Quality, and wetlands with scores of 65 or greater received a High Quality rating. Some wetland quality ratings were adjusted up or down based upon professional judgxnent. A table listing each wetland, the DWQ rating and wetland type (Cowardin Classification) can be found in Appendix C. Table 6 presents the quality and number of wetlands in each alternative. It should be noted that not all wetlands within the approximate 1,400-foot study corridor will be impacted by construction of the project Table 6.

PEMl - These are palustrine emergent wetlands consisting of persistent emergent vegetation. These wetlands are located in areas such as pastures, road sides or maintained easements typically in headwaters or along floodplains of streams. Some common species in these wetlands include soft nxsh (Tuncus effusus), bulnxsh (Scirpus validus), beggar's ticks (Bidens aristosa), bushy seedbox (Ludwigia alternifolia), netted chain fern, (Woodwardia areolata), cinnamon fern (Osmunda cinnamomea), giant cane (Arundinaria gigantea), cattail (Typha latifolia), blackberry (Rubus sp.), tag alder (Alnus serrulata), and black willow (Salzx nigra). Hydrology is dependant upon landscape position and is typically groundwater or flood driven due to the location of these wetlands along streams. These areas can be saturated (PEM1B), seasonally flooded (PEM1C), semi-perxnanently flooded (PEM1F), interxnittently exposed (PEM1G), and interxnittently flooded (PEMl�. A good example of this wetland type is Wetland 159. Pebruary 2008 23 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina PFOl - These are palustrine forested wetlands consisting of broad leaved deciduous vegetation. Many of these wetlands are in the headwaters or floodplains of streams and are hydrologically driven by groundwater or flooding. Typical vegetation species include red maple (Acer rubrum), sweetgum (Liguidambar styraciflua), willow oak (Quercus phellos), bxlip poplar (Liriodendron tulipifera), spicebush (Lindera benzoin), downy arrowwood (Viburnum dentatum), Chinese privet (Ligustrum sinense), Japanese grass (Microstegium vimineum), and netted chain fern. Hydrology is dependant upon landscape position and is typically groundwater or flood driven due to the location of these wetlands along streams. These wetlands can be temporarily flooded (PFOlA), sabxrated (PFO1B), seasonally flooded (PFO1C), a combination of seasonally flooded or sabxrated (PFOlE), semi-perxnanently flooded (PFO1F), intermittently exposed (PFO1G), and interxnittently flooded (PFO1�. A good example of this wetland type is Wetland 34. PSSl - These are palustrine shrub-scrub wetlands composed of broad-leaved deciduous vegetation that is less than 20 feet in height. Many of these wetlands are in the headwaters or floodplains of streams and are hydrologically driven by groundwater or flooding. Species common to these wetlands include tag alder, willow oak, Chinese privet, blackberry, and poison ivy (Toxicodendron radicans). These often occur along the edges of the emergent wetlands or are forested systems that have been logged. Hydrology is variable and based upon landscape position. These wetlands can be temporarily flooded (PSS1A), saturated (PSS1B), seasonally flooded (PSS 1C), and semi-perxnanently flooded (PSS 1F). A good example of this wetland type is Wetland 189. PSS3C - These are palustrine shrub-scrub wetlands composed of broad-leaved evergreen vegetation that is less than 20 feet in height and are seasonally flooded. Many of these wetlands are in the headwaters or floodplains of streams and are hydrologically driven by groundwater or flooding. Common species include giant cane, Chinese privet, and Japanese honeysuckle. One of the few examples of this wetland type is Wetland 27. PUBHh - These are palustrine wetlands with unconsolidated bottoms and are perxnanently flooded due to dikes or impoundments. These are farm ponds or other types of manxnade ponds that have been constructed by damming a stream or excavating in the headwaters of a drainage system. A good example of this wetland type is Wetland 119. All of the named streams, unnamed tributaries, and ponds meet the definition of surface waters, and are therefore, classified as Waters of the United States. Numerous perennial and intermittent streams were identified in the project study area (Figure 3a-3w). Appendix F contains the NCDWQ Stream Identification forms used to deterxnine interxnittent and perennial status. Appendix G contains the USACE Stream Quality Assessment Warksheet Additional information on each stream can be found in Appendix C. In 2006, the Supreme Court addressed the jurisdictional scope of Section 404 of the CWA, specifically the terxn "the waters of the U.S.," in Rapanos v. U.S. and in Carabell v. U.S. (hereafter referred to as Rapanos). The decision provided two new analytical standards for deterxnining whether water bodies that are not traditional navigable waters (TNWs), including wetlands adjacent to those non-TNWs, are subject to CWA jurisdiction: (1) if the water body is relatively permanent, or if the water body is a wetland that directly abuts (e.g., the wetland is not separated from the tributary by uplands, a berxn, dike, or similar feature) a relatively perxnanent water body (RP�, ar(2) if a water body, in combination with all wetlands adjacent to that water body, has a significant nexus with TNWs. As a consequence of the U.S. Supreme Court decision in Rapanos, the EPA and the USACE, in coordination with the Office of Management and Pebruary 2008 24 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Budget (OMB) and the PresidenYs Council on Environxnental Quality (CE�, developed the Memorandum Regarding Clean WaterActJurisdiction Follawing Rapanos v. United States. This guidance requires the application of the two new standards described above, as well as a greater level of documentation, to support an agency JD for a particular water body. Furthermore, this guidance required the USACE and EPA to develop a revised JD form to be used by field staff for documenting assertion or declination of CWA jurisdiction. These forms were completed for project streams and wetlands and are included as Appendix H. Many of the wetlands within the project study area are abutting the stream or surface water body they are associated with. Alxnost all wetlands that were adjacent (nearby but not directly abutting a stream) were deterxnined to have a significant nexus with the stream and with Navigable Waters of the US. Four wetlands were determined to not have a significant nexus. These wetlands were Wetland 95, Wetland 252, Wetland 253, and Wetland 291. 4.1.2 Catawba River Riparian Buffer Rules Perxnanent riparian buffer protection rules were enacted far the main stem of the Catawba River below Lake James to The NGSC border (NCDWQ, 2004). These rules also encompass the seven mainstem lakes from Lake James to the NGSC border. Lake Wylie is one of the mainstem lakes in which the buffer rules apply. The buffer protection rules apply within 50 feet of all riparian shorelines along the Catawba River mainstem and the seven mainstem lakes. The buffer is 50 feet wide and is measured from the waters edge (at full pond in the lakes) and has two zones of 30 feet (Zone 1 nearest the water) and 20 feet (Zone 2landward of Zone 1). Grading and clearing of vegetation in Zone 1 is not allowed except for certain uses. The outer 20-foot zone (Zone 2) can be cleared and graded but it must be revegetated and maintain diffuse flow to Zone 1. Certain activities (including road crossings) may be allowable with mitigation but must first be reviewed and given written approval by DWQ staff. If it can be shown that there are "no practical alternatives" to the proposed activity, a variance may be allowed with mitigation. The project crosses three water bodies that are part of Lake Wylie in which the Catawba River Riparian Buffer Rules will apply. These are stream segxnents that are flooded due to the presence of Lake Wylie and are: Catawba Creek, South Fark Catawba River, and the Catawba River. Catawba Creek only occurs on the southern half of the southernmost "alternative segxnent" and has potential to be avoided during the alternatives analysis. 4.1.3 Summary ofAnticipated Impacts Project conshuction cannot be accomplished without infringing on the surface waters. Anticipated surface water impacts fall under the jurisdiction of the USACE and the DWQ. Wetlands may be either partially or completely filled. In some instances larger wetland areas may become hydraulically disconnected from an adjacent stream. Streams may be filled, relocated, or culverted by project conshuction. Table 7 presents the amount of streams and wetlands that could be potentially impacted by each alternative. Impacts are based upon the preliminary design as of January 1, 2007. The impacts were calculated using the slope stake lines with a 25-foot buffer added to account for future changes in design.

Therefore, it will be necessary to submit an Individua1404 Permit application to the USACE for stream and wetland impacts. This project will also require a 401 Water Quality Certification from the NCDENR priar to issuance of the Individual 404 Permit. Section 401 of the CWA requires that the state issue or deny water certification for any federally perxnitted or licensed activity that results in a discharge into Waters of the United States. Final perxnit decision rests with the USACE. Impacts to the Catawba River riparian buffer rules will likely occur once it is shown that no practicable alternatives exist far the project. The buffer rules state that bridging is an allowable action within the buffers and mitigation will not be required. 4.2.2 Mitigation The function of avoidance, minimization, and mitigation is to restore and maintain the chemical, biological, and physical integrity of Waters of the United States and Catawba River riparian buffers by avoiding impacts, minimizing impacts, and rectifying impacts. Each of these three aspects (avoidance, minimization, and compensatory mitigation) must be considered sequentially. 4.2.2.1 Avoidance Pebruary 2008 � Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Avoidance mitigation examines all appropriate and practical possibilities of averting impacts to Waters of the United States and Catawba River riparian buffers. According to a 1990 Memorandum of Agreement (MOA) between the Environxnental Protection Agency (EPA) and USACE, in deterxnining "appropriate and practical" measures to offset unavoidable impacts, such measures should be appropriate to the scope and degree of those impacts and practical in terms of costs, existing technology, and logistics in light of overall project purposes. 4.2.2.2 Minimization Minimization includes the examination of appropriate and practical steps to reduce the adverse impacts to Waters of the United States and Catawba River riparian buffers. Implementation of these steps will be required through project modifications and perxnit conditions. Practical means to minimize impacts to surface waters and wetlands impacted by the proposed project include: • Decreasing the footprint of the proposed project through the reduction of inedian width, right- of-way widths, fill slopes and/or road shoulder widths • Installation of temporary silt fences, earth berms, and temporary ground cover during construction • Strict enforcement of sedimentation and erosion control BMPs far the protection of surface waters and wetlands • Reduction of clearing and grubbing activity in and adjacent to water bodies • Judicious pesticide and herbicide usage 4.2.2.3 Compensation Compensatory mitigation is not norxnally considered until anticipated impacts to Waters of the United States have been avoided and minimized to the maximum extent possible. Appropriate and practicable compensatory mitigation is required for unavoidable adverse impacts that remain after all appropriate and practicable minimization has been done. 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 (i.e., compensatory on-site mitigation). There are many possible streams in the project sbxdy area that restoration of which may qualify as on-site mitigation for stream impacts. Because this project will likely be permitted under an Individual 404 Permit, mitigation for impacts to surface waters will be required by the USACE and the Division of Water Quality. Furtherxnore, in accordance with 72 FR 11092; 11198; March 12, 2007, the USACE requires compensatory mitigation when necessary to ensure that adverse effects to the aquatic environment are minimal. It is anticipated that stream impacts will be greater than USACE and DWQ regulatory thresholds and will require compensatory mitigation. The environxnental regulatory agencies will ultimately provide final perxnit and compensatory mitigation decisions far the project It is also anticipated that Catawba River riparian buffers may be impacted. These impacts will be from bridging, which is an allowable impact and does not require mitigation. 4.3 Federally Protected Species 27 Pebruary 2008 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Some populations of plants and animals are declining either as a result of natural forces or their difficulty competing with humans for resources. Rare and protected species listed for Gaston and Mecklenburg Counties, and any likely impacts to these species as a result of the proposed project construction, are discussed in the following sections. 4.3.1 Species Under Federal Protection Plants and animals with a federal classification of Endangered (E), Threatened ('1�, Proposed Endangered (PE), and Proposed Threatened (PT) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. The USFWS lists three species (list updated May 10, 200'� under federal protection for Gaston County and five species (list updated May 10, 200'n under federal protection far Mecklenburg County.

Surveys for federally protected species are valid for two years from the survey date. If the project is not constructed within those two years then the area may need to be resurveyed priar to the let date. Bald eagle (Hnlineetus leucocephalus) Family: Accipitridae Date First Listed: March 11, 1967 � Delisted Pebruary 2008 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Date Downlisted: July 12, 1995 Date Delisted: August 8, 2007 The bald eagle is a large raptor with a wingspan reaching 7 feet (2.1 m). Adults have a dark brown body with a pure white head and tail, whereas the juvenile plumage is chocolate brown to blackish with white mottling on the tail, belly and underwings. Adult plumage is fully acquired by the fifth or sixth year. The bald eagle is primarily associated with coasts, rivers, and lakes, usually nesting near large bodies of water where it feeds. It preys primarily on fish, but will feed on birds, mammals, turtles, and carrion when fish are unavailable. In the southeast, the nesting and breeding season runs from September to December. Large nests up to 6 feet (2 m) across and weighing hundreds of pounds are constructed from large sticks, weeds, cornstalks, grasses, and sod. Preferred nesting sites are usually within one-half mile of water, have an open view of the surrounding area, and are in the largest living tree, usually a pine or cypress. Excessive human activity may exclude an otherwise suitable site from use. Wintering areas generally have the same characteristics as nesting sites, but may be farther from shores. The bald eagle ranges throughout all of North America. Breeding sites in the southeast are concentrated in Florida, coastal South Carolina, and coastal Louisiana, and sporadically located elsewhere. Bald eagles were first listed as Endangered in 1967 due to population decline caused by DDT and other factors. Since this listing the population of eagles in the lower 48 states has increased from 487 breeding pairs to an estimated 9,789 breeding pairs in 2007. Due to this recovery and additional protection provided by the Bald and Golden Eagle Protection Act (BGEPA) and the Migratory Bird Treaty Act (MBTA), the eagle was removed from the list of endangered species in 2007. Biological Conclusion None Required An aerial survey of the Lake Wylie area within the project study area and extending outward one mile was perforxned by helicopter on December 19, 2006. Areas along the shoreline and adjacent to the shoreline were surveyed for the presence of large nests and areas with historical nest data were surveyed thoroughly in an attempt to relocate the nest. Three unoccupied large nests were observed during this survey outside of the project study area. These nests were ground truthed by Earth Tech biologists using a spotting scope and binoculars on February 8, 2007 to deterxnine the species using the nests during the nesting season for the bald eagle. Two of the nests were found to be occupied by great blue herons. The third nest, located in an electrical transmission tower, did not appear to be sufficiently large for bald eagles and is thought to be an osprey nest. Two documented eagle nests have occurred at one point on Lake Wylie. One confirmed eagle nest was observed in a location that has been tracked by the NC Wildlife Resources Commission (NCWRC). The NCWRC provided location data far this occurrence (Gaston # 1) and has tracked fledgling survival during previous years. The nest was observed in a relatively new subdivision southeast of Belmont and is surrounded by homes at the end of Deas Drive (approximately 1.6 miles north of the project study area). Deas Drive is located off of Amanda Lane in Gaston County. Two adult eagles were observed in the general area and one of these eagles was Pebruary 2008 29 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina observed on the nest on February 8, 2007. A memorandum documenting the bald eagle surveys is provided in Appendix A. Earth Tech biologists were not able to locate the second documented nest site which is reported to be approximately 0.5 miles south of the project study area boundary on Worrels River Road. There are no bald eagle nests within the project study area. The closest observed nest is about 1.6 miles north of the project study area. Therefore, it is likely that eagles forage for fish within the project study area. Because the bald eagle is no longer listed as a threatened or endangered species it is no longer protected under the Endangered Species Act. However, the eagle is still protected under the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act Continued coordination with the USFWS is recommended to insure that provisions within these two Acts are met. Bog turtle (Clemmys muhlenbergia) Threatened (Similarity of Appearance) Vertebrate Family: Emydidae Federally Listed: 1997 The bog turtle is a small freshwater turtle reaching a maximum carapace length of 11.4 cm (4.5 in). These turtles have a domed carapace that is weakly keeled and is light brown to ebony in color. The scutes have a lighter�olored starburst pattern. The plastron is brownish-black with contrasting yellow or cream areas along the midline. This species is distinguished by a conspicuous orange, yellow, or red blotch on each side of the head. The bog turtle is semi-aquatic and is typically found in freshwater wetlands characterized by open fields, meadows, or marshes with slow-moving streams, ditches, and boggy areas. The bog turtle is also found in wetlands in agricultural areas subject to light to moderate livestock grazing, which helps to maintain an interxnediate stage of succession. During the winter, this species hibernates just below the upper surface of mud. Mating occurs in May and June, and the female deposits two to six eggs in sphagnum moss or sedge tussocks in May, June, or July. The diet of the bog turtle is varied, consisting of beetles, lepidopteran and caddisfly larvae, snails, millipedes, pondweed and sedge seeds, and carrion. The southern population of the bog turtle is listed as Threatened due to Similarity of Appearance to the northern population, therefore, the southern population is not afforded protection under Section 7 of the Endangered Species Act. Biological Conclusion None Required Potential habitat exists far this species in the project study area. Numerous emergent and shrub scrub wetlands that may be suitable far the species exist in the project study area. Suitability of these wetlands as bog bxrtle habitat was determined based on descriptions and/or photographs of the wetlands in the delineation reports provided by field crews. Habitat suitability of the wetlands was not field verified and no site specific searches far the bog turtle have been perforxned. The following emergent wetlands were identified as potential habitat for bog bxrtles: 1, 8, 19, 25, 31, 35, 58, 64, 73, 78, 110, 117, 141A, 144, 145, 159, 219, 228/229, 230, 231, and 232. The following shrub scrub wetlands were identified as potential habitat for bog turtles: 11, 29, 46, 111, 120, 137, and 233. A search of the NHP database did not reveal any occurrences of the bog Pebruary 2008 30 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina turtle within the project study area. There is an occurrence of the bog turtle approximately 2.5 miles NW of the project study area in Gaston County. Two additional occurrences are approximately 4.3 miles northeast of the project study area. Carolina heelsplitter (Lasmigona decoraLa) Endangered Invertebrate Family: Unionidae Date Listed: 6-30-93 The Carolina heelsplitter is a greenish brown to dark brown mussel, often with faint greenish brown to black rays on the younger specimens. The unsculptured shell is ovate and trapezoidal. The largest known specimen measures 4.6 inches (114.8 mm) in length, 1.56 inches (39.0 mm) in width, and 2.7 inches (68.0 mm) in height The nacre is pearly white to bluish white, grading to orange near the umbo. The entire nacre may be mottled orange in older specimens. Historic records repart the Carolina heelsplitter occurring in small to large streams and rivers as well as ponds, probably mill ponds on small streams. Current records report populations occurring in six small streams and one small river. The substrate where the heelsplitter is found is usually mud, muddy sand, or muddy gravel in streams with stable, well-shaded banks. A South Carolina population was found in a sand, gravel, and cobble substrate. The historic distribution of the Carolina heelsplitter included the Catawba and Pee Dee River systems in North Carolina (Mecklenburg, and the Pee Dee and Savannah River systems and possibly the Saluda River in South Carolina. Currently, only four populations are known to exist. In Union County, NC, two small populations are known from Waxhaw Creek (Catawba River system) and Goose Creek (Pee Dee River system). In Chesterfield, Lancaster, and Kershaw Counties in South Carolina, a third, slightly larger population is known from the Lynches River (Pee Dee River system) and extends into Flat Creek, a tributary of the Lynches River. A fourth population is known from the Turkey Creek (Savannah River system) and two of its tributaries, Mountain Creek and Beaverdam Creek, in Edgefield County. The decline of the Carolina heelsplitter is attributed to siltation and habitat alterations caused by agricultural, forestry, and development activities; road and golf course construction; runoff and discharge of municipal, industrial, and agricultural pollutants; impoundments, channelization, dredging, and sand mining; and other factors having an adverse effect on the aquatic environment. Biological Conclusion No Effect A survey for freshwater mussels took place on September 15, 16, and 21 in 2005 by NCDOT biologists. Biologists looked at 28 streams that could be potentially crossed by the proposed Gaston East-West connector. Thirty sites on these streams were assessed utilizing a standard freshwater mussel screening protocol or an assessment of mussel habitat. Named streams surveyed for freshwater mussels included: Oates Creek, Bessemer Branch, Crowder's Creek, McGill Branch, Mill Creek, Myrtle Creek, Catawba Creek, and Beaverdam Creek. No freshwater mussels were found in any of the surveyed streams. A memorandum documenting the surveys can be found in Appendix A. Because freshwater mussels were not found in any of the surveyed streams, it is concluded that the Carolina Heelsplitter does not occur in the project vicinity. The NCNHP does not list any known population up or downstream in any of the above-mentioned streams, which all flow into Pebruary 2008 31 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina the Catawba River. There are no known occurrences in the Catawba River up or downstream of the confluences of these streams. The Gaston East-West connector project will have no effect on the Carolina Heelsplitter (NCDOT, 2005). Michaux's sumac (Rhus michauxu) Family: Anacardiaceae Federally Listed: 1989 Endangered Michaux's sumac or false poison sumac is a densely hairy colonial shrub with erect stems, which are 1 to 3 feet in height. The shrub's compound leaves are narrowly winged at their base, dull on their tops, and veiny and slightly hairy on their bottoms. Each leaf is finely toothed on its edges. Flowers are greenish-yellow to white and are 4 to 5-parted. Each plant is unisexual. With a male plant the flowers and fruits are solitary, with a female plant all flowers are grouped in 3 to 5 stalked clusters. The plant flowers from April to June; its fruit, a dull red drupe, is produced in October and November. Michaux's sumac grows in sandy or rocky open woods in association with basic soils. Apparently, this plant survives best in areas where some form of disturbance has provided an open area. Most of the p1anPs remaining populations are on highway rights-of-way, roadsides, or on the edges of artificially maintained clearings. Other populations are in areas with periodic fires, or on sites undergoing natural succession. Biological Conclusion No Effect Potential habitat for Michaux's sumac occurs throughout the project study area. Surveys of suitable habitat were performed in 2005. No populations of Michaux's sumac were found during these surveys. The NCNHP record for Michaux's sumac is historic and nearly all of the area has been developed, farmed, and otherwise negatively impacted for suitable habitat. NCNHP records did not document the location of any known populations of the sumac within one mile of the project study area. Based on the results of this survey, the project will not impact any Michaux's sumac populations within the area surveyed. This project will have no effect on any populations of Michaux's sumac (PBS & J, 2006). The survey far this species is good far two years. The report documenting the 2005 survey can be found in Appendix A. Schweinitz's sunflower (HeFianthus schweiniLZU) Endangered Plant Family: Asteraceae Date Listed: 5-7-91 Schweinitz's sunflower is a rhizomatous perennial herb that grows from 3 to 6 ft(1 to 2 m) tall from a cluster of carrot-like tuberous roots. Stems are usually solitary, branching only at or above mid-stem. The stem is usually pubescent but can be nearly glabrous; it is often purple. The lanceolate leaves are opposite on the lower stem, changing to alternate above. They are variable in size, being generally larger on the lower stem, and gradually reduced upwards. The pubescence of the underside of the leaves is distinctive and is one of the best characters to distinguish Schweinitz's sunflower from its relatives. The upper surface of the leaves is rough, with the broad-based spinose hairs directed toward the tip of the lea£ From September to frost, Schweinitz's sunflower blooms with comparatively small heads of yellow flowers. The species occurs in clearings and edges of upland woods on moist to dryish clays, clay-loams, or sandy clay-loams that often have high gravel content and are moderately podzolized. Pebruary 2008 32 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina Schweinitz's sunflower usually grows in open habitats not typical of the current general landscape in the piedmont of the Carolinas. Some of the associated species, many of which are also rare, have affinities to glade and prairie habitats of the Midwest. Other species are associated with fire- maintained sandhills and savannas of the Atlantic Coastal Plain and piedmont. The habitat of this sunflower tends to be dominated by members of the aster, pea, and grass families, an association emphasizing affinities of the habitat to both longleaf pine-dominated sandhills and savannas of the southeastern coastal plain and to glades, barrens, and prairies of the Midwest and Plains (USFWS, 1994). Biological Conclusion May AffecU Not Likely to Adversely Affect The powerlines, roadsides and open areas within the project study area are high probability areas for potentially suitable Schweinitz's sunflower habitat. These high probability areas were surveyed far the presence/absence of Schweinitz's sunflower in 2005. One population of Helianthus schweinitzii was observed within the project study area. This population is located on the northern edge of the narthernmost Detailed Study Corridor, south of Catawba Creek along the western side of SR 2435 (Union-New Hope Road) (Figure �. Due to its location in the Detailed Study Corridors, it may be possible to avoid all impacts to the observed Schweinitz's sunflower population (PBS & J, 200�. NCNHP records indicate that there is one known Schweinitz's sunflower population about 4,900 feet south of the project study area. This population is located on SR 2650 approximately 3,650 feet nartheast of the intersection of SR 2650 and SR 2431. The survey for this species is good for two years. The report documenting the 2005 survey can be found in Appendix A. Smooth coneflower (Echinacea laevigata) Endangered Family: Asteraceae Date First Listed: October 1992 The smooth coneflower is a rhizomatous perennial herb that grows up to 49 feet (1.5 m) ta1L The largest leaves are the basal leaves, which reach 7.8 inches (20 cm) in length and 3 inches (7.5 cm) in width. The basal leaves have long stems, are elliptical to broadly lanceolate, tapering to the base, and smooth to slightly rough. The plant has smooth stems with few cauline leaves. The rays of the flowers (petal-like strucbxres) are light pink to purplish, usually drooping, and 19 to 3.1 inches (5 to 8 cm) long. Flower heads are usually solitary. Flowering occurs from May through July. The known range of the smooth coneflower consists of 22 populations found now only in Virginia, North Carolina, South Carolina, and Georgia. Six of the populations are in North Carolina and are found in Durham and Granville counties. Most of the populations are small, containing less than 100 plants each. Four of the populations contain less than 10 plants each. In North Carolina the habitat of smooth coneflower is open woods, cedar barrens, roadsides, clearcuts, dry limestone bluffs, and power line rights-of-way, usually on magnesium- and calcium-rich soils associated with gabbro and diabase. Optimal sites are characterized by full sunlight and little competition in the herbaceous layer (Gaddy 1991). Natural fires, as well as large herbivores, are part of the history of the vegetation in this species' range and many of the Pebruary 2008 33 Natural Resources TecYmical Report Gaston East-West Connector, Gaston and Mecklenburg Counties, North Carolina associated herbs are also sun-loving species, which depend on periodic disturbances to reduce the shade and competition of woody plants (Kral 1983 and Gaddy 1991). The major factors contributing to endangered status of this species are collecting, residential and industrial development, shade from woody vegetation, highway construction and improvement, and certain types of roadside and power line right-of-way maintenance. Like most coneflowers, this species is intolerant of dense shade. Biological Conclusion No Effect Habitat far the smooth coneflower is present in the project sbxdy area. Suitable habitat for smooth coneflower within the project study area was surveyed in 2005, but no populations of smooth coneflower were found. NCNHP records did not document the location of any known populations of the smooth coneflower within one mile of the project study area. Based on the results of this survey, the project will not impact the smooth coneflower within the area surveyed. This project will have no effect on any smooth coneflower populations (PBS & J, 2006). The survey for this species is good for two years. The report documenting the 2005 survey can be found in Appendix A. 4.3.2 Federal Species of Concern, Candidate and State Status Federal Species of Concern (FSC) and Candidate (C) species are not legally protected under the Endangered Species Act and are not subject to any of its provisions, including Section 7, until they are formally proposed or listed as Threatened or Endangered.

BIOLOGICAL CONCLUSION: No Effect Given the survey results, that no freshwater mussels were found in the Tributary Abernathy Creek, Oates Creek, Bessemer Branch, Tributaries Crowders Creek, Crowders Creek, McGill Branch, Mill Creek, Tributaries Catawba Creek, Catawba Creek, Tributaries South Fark Catawba River, Tributaries Catawba River and Beaverdam Creek, it is apparent that the Carolina Heelsplitter does not occur in the project vicinity. The North Carolina Natural Heritage Program (NCNHP) does not list a known population up or downstream in any of the above-mentioned streams, which all flow into the Catawba River. There are no known occurrences in the Catawba River up or downstream of the confluence's of these streams. The proposed Gaston East-West Connector project will have no effect on the Carolina Heelsplitter. cc: Chris Manley, Project Manager File: U-3321 Bogan, Art, 2002.

The proposed Gaston County East-West Connedor (U-3321) around the city of Gastonia includes 16 alternatives (endpoint to endpoint) which extend from south of the Charlotte Douglas Intemational Airport in western Mecklenburg County, south of Gastonia, to a link with Interstate 85 Q-85) just west of Gastonia in Gaston County for a total of approximately 72 corridor miles. Corridor width for each altemative averages 1400 feet (Figure 1). The following memorandum addresses surveys for the Bald Eagle (Haliaeetus leucocephalus), a federally proteded species listed by the U.S. Fish and Wldlife Service for Gaston and Mecklenburg Counties pertormed as part of the environmental requirements associated with the Gaston East-West Connector projed. The bald eagle is primarily associated with coasts, rivers, and lakes and usually nests near large bodies of water where it feeds. Large nests up to 6 feet (2 m) across and weighing hundreds of pounds are construded from large sticks, weeds, comstalks, grasses, and sod. Preferred nesting sites are usually within one-half mile of water, have an open view of the surrounding area, and are in the largest living tree, usually a pine or cypress. In the southeast, the nesting and breeding season runs from September to December. Bald eagles are known from Lake Wylie and the NC Wfldlife Resources Commission (NCWRC) and NC Natural Hentage Program (NCNHP) each had data on separate bald eagle nest locations. An aerial survey of the Lake Wylie area within the project area and eutending outward one mile was pertormed by helicopter on December 19, 2006. Areas along the shoreline and adjacent to the shoreline were surveyed for the presence of large nests and areas with historical nest data were surveyed thoroughly in an attempt to relocate the nest. Three unoccupied large nests (Figure 2) were observed during this survey outside of the projed study area, one of which was near the NCNHP tracked nest location. These nests were ground truthed by Earth Tech biologists using a spotting scope and binoculars on February 8, 2007 to determine the species using the nests during the nesting season for the bald eagle. Two of the nests were found to be occupied by great blue herons. The third nest, located in an electrical transmission tower, did not appear to be sufficiently large for bald eagles and is thought to be an osprey nest. One confrmed eagle nest was observed in a location that has been tracked by the NC Wldlife Resources Commission (NCWRC). The NCWRC provided location data for this occurrence (Gaston #1) and has tracked fledgling survival during previous years. The nest was observed in a relatively new subdivision southeast of Belmont and is surrounded by homes at the end of Deas Dnve (approximately 1.6 miles north of the study corridor). Deas Drive is located off of Amanda Lane in Gaston County. Two adult eagles were observed in the general area and one of these eagles was observed on the nest on February 8, 2007. This was the only documented eagle nest observed during the survey. The nest location is depicted in Figure 3. An additional nest location that was provided by the NC Natural Heritage Program is actually an incorrectly plotted reference to Gaston #1 that we observed and is described above. This location does not have a current or historic eagle nest location associated with it. Due to the small possibility of impacting foraging habitat with the potential construction of a bridge over Lake Wylie, a biological conclusion of May Affect, Not Likely to Adversely Affect was reached. Bald eagle (Haliaeetus /eucocepha/us) May Affect, Not Likely to Adversely Affect The following biological conclusion was reached after surveys and research associated with this project. Surveys for federally protected species are valid for two years from the survey date. If the project is not constructed within those two years then the area may need to be resurveyed prior to the let date.

Schweinitz's Sunflower Population U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary March 2006 1.0 Introduction 1.1 Project Description The North Carolina Turnpike Authority is studying alternatives associated with the development of a candidate toll road facility on new location in Gaston and Mecklenburg Counties, North Carolina. The proposed Gaston County East-West Connector Sbxdy (TIP Project No. U-3321) includes sixteen Detailed Study Alternatives (endpoint to endpoint) which extend from Interstate 85 (I-85) west of Gastonia in Gaston County to I-485/NC 160 west of the Charlotte Douglas International Airport in western Mecklenburg County. There are approximately 72 miles of corridor. The corridor width averages 1,400 feet, with wider areas around potential interchange locations. 1.2 Purpose of this Report This report is a summary of the surveys for protected plant species conducted along the Detailed Study Corridors in September through October 2005. The corridors comprising the Detailed Study Alternatives were partitioned into four survey segments for purposes of surveying for federally-protected plant species, as shown in Figures la and lb. A consultant group was selected for each of the four survey segxnents, and they were responsible for surveying for protected plant species listed as Threatened or Endangered by the US Fish and Wildlife Service (USFWS) that have ranges which extend into Gaston ar Mecklenburg Counties. The four consultant groups and the survey segments are described below. Each consultant prepared a survey report far their respective segxnent, as listed in the References Section of this document. Survey Segment 1 Kimley-Horn and Associates (KHA) surveyed Segxnent 1, which includes all Detailed Sbxdy Alternative corridors from I-485 west to the Gaston/Mecklenburg County line at the Catawba River. The Segxnent 1 corridor study area contains approximately 1,800 acres. Survey Segment 2 Environmental Services, Inc. (ES� surveyed Segxnent 2, which begins at the Gaston/ Mecklenburg County line at the Catawba River and includes all Detailed Study Alternative corridors west to NC 274, a distance of approximately 7 miles. The Segxnent 2 corridor sbxdy area contains approximately 4,205 acres. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary March 2006 Survey Segment 3 HW Lochner (Lochner) surveyed Segxnent 3, which includes all Detailed Sbxdy Alternative corridors between NC 274 and Lewis Road (SR 1128)/Chapel Grove Road (SR 1131)/Linwood Road. The Segxnent 3 corridor study area contains approximately 4,758 acres. Survey Segment 4 Earth Tech surveyed Segxnent 4, which includes all Detailed Study Alternative corridors from Lewis Road (SR 1128)/Chapel Grove Road (SR 1131)/Linwood Road north to I-85 in Gaston County. The Segxnent 4 corridor study area contains approximately 3,700 acres. 2.0 Plant Species Profiles Federal law under the provisions of Section 7 of the Endangered Species Act (ESA) of 1973, as amended, requires that any action likely to adversely affect a federally-protected species be subject to review by the USFWS. Other species may warrant protection under separate state laws. 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 ESA. 2.1 Plants Listed for Mecklenburg County As of November 10, 2005, the USFWS internet listing far Mecklenburg County identifies three plant species listed as endangered: Michaux's sumac (Rhus michauxii), smooth coneflower (Echinacea laevigata), and Schweinitz's sunflower (Helianthus schweinitzii). An endangered species is one in danger of extinction throughout all or a significant portion of its range. The survey window (as designated by USFWS) for all three species varies; however, the survey window for all three plants overlaps from mid-August to the end of October. "Critical habitat," as defined in the ESA, is a term for habitat given special protection far the benefit of a listed species. Critical habitat, as defined by the USFWS, is not designated for any species listed in Mecklenburg County, North Carolina. In addition, according to the NC Natural Heritage Program (NCNHP) database (October 19, 2005), no federally threatened, endangered, or species of concern listed by the USFWS have been documented within a 1-mile radius of the Detailed Study Corridor areas in Mecklenburg County. Survey Segxnent 1 is the portion of the project's Detailed Sbxdy Alternatives that is within Mecklenburg County. The three listed plant species far Mecklenburg County are described below. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 2 March 2006 Species: Michaux's sumac (Rhus michauxii) Plant Family: Anacardiaceae Status: Endangered Date Listed: September 28, 1989 Critical Habitat: None identified in Mecklenburg County, NC Michaux's sumac is a rhizomatous, densely hairy shrub. There are nine to thirteen sessile leaflets that are oblong to oblong-lanceolate. The leaflet margins are simple to double serrated with a rounded base. The flowers are small, borne in a terxninal, erect, dense cluster, and colored greenish yellow to white. Flowering usually occurs from June to July; while the fruit, a red drupe, is produced through the months of August to October (USFWS 2005). Michaux's sumac typically grows in sandy or rocky open wooded areas in association with basic soils. In order to maintain the preferred open wooded areas, Michaux's sumac is commonly found in areas of maintained disturbances. The maintained disturbed areas such as power line easements, railroad rights-of-way, and road rights-of-way replicate the open quality of habitat typically supplied by naturally occurring periodic fires (USFWS 1993). Species: Smooth coneflower Plant Family: Asteraceae Status: Endangered Date Listed: October 8, 1992 Critical Habitat: None identified in Mecklenburg County, NC Smooth coneflower is a tall rhizomatous perennial herb that grows up to five feet in height The stems are smooth with leaves that are lance-ovate to elliptia The smooth to slightly pubescent leaves are acuminate with often course serrations. The ray flowers (two to three inches long) are light pink to purple, usually drooping. Flower heads are usually solitary with flowering occurring from May through July (USFWS 2005). Smooth coneflower typically inhabits open woods, cedar barrens, roadsides, clearcuts, dry limestone bluffs, and power line rights-of-way. The smooth coneflower is associated with the gabbro and diabase parent material soil types, which are usually rich in magnesium and calcium (USFWS 1995). U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary March 2006 Species: Schweinitz's sunflower (Helianthus schweinitzii) Plant Family: Asteraceae Status: Endangered Date Listed: May 7, 1991 Critical Habitat: None identified in Mecklenburg County, NC Schweinitz's sunflower is a rhizomatous perennial herb that grows from 3 to 6 ft(1 to 2 m) tall from a cluster of carrot-like tuberous roots. Stems are usually solitary, branching only at or above mid-stem. The stem is usually pubescent but can be nearly glabrous; it is often purple. The lanceolate leaves are opposite on the lower stem, changing to alternate above. They are variable in size, being generally larger on the lower stem and gradually reduced upwards. The pubescence of the underside of the leaves is distinctive and is one of the best characters to distinguish Schweinitz's sunflower from its relatives. The upper surface of the leaves is rough, with the broad-based spinose hairs directed toward the tip of the lea£ From September to frost, Schweinitz's sunflower blooms with comparatively small heads of yellow flowers. According to the US Fish and Wildlife Service, the current range of this species is within 60 miles of Charlotte, North Carolina. It occurs on upland interstream flats or gentle slopes, in soils that are thin or clayey in texture. Schweinitz's sunflower is typically found on the following soil types: Iredell, Enon, Badin, Cecil, Misenheimer, Gaston, and Zion soils. It may also occur in Tatum, Cid, Secrest, Georgeville, Mecklenburg, and Uwahrrie soil types. This species needs open areas protected from shade or excessive competition, reminiscent of Piedmont prairies. Disturbances such as fire maintenance or regular mowing help sustain preferred habitat. The typical suitable habitat far this sunflower includes upland clearings, forest edges, roadsides, utility corridors, pastures, thickets, and woodland openings. Schweinitz's sunflower is usually found on well-drained, shallow, poor, clayey, or rocky soils. Threats to this species include; fire suppression, urbanization, conversion of habitat to pine plantations, right-of-way maintenance, and small population size. 2.2 Plants Listed for Gaston County As of September 30, 2005, Schweinitz's sunflower (Helianthus schweinitzii) is the only plant species listed by the US Fish and Wildlife Service (USFWS) as Threatened or Endangered that has a range extending into Gaston County, NC. The survey window (as designated by USFWS) far this species extends from late August through the end of October. Survey Segxnents 2, 3, and 4 are entirely within Gaston County. Please refer to the description of Schweinitz's sunflower included in Section 2.1. No critical habitat far this sunflower has been designated by the US Fish and Wildlife Service in Gaston County. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 4 March 2006 3.0 Survey Methodologies 3.1 Survey Segment 1- Mecklenburg County The initial analysis (search) far the protected species began with a review of available mapping. Qualified biologists from KHA reviewed available aerial photography, soils mapping, and corridor mapping to deterxnine potential habitat areas deemed suitable for survey far the three plant species in Mecklenburg County (called "priority habitat areas" in KHA's report). Areas that were likely to have suitable habitat were identified and delineated on the aerial photography. A brief drive-by window survey of the project area was conducted to confirxn location and the extent of suitable habitat. Michaux's sumac, smooth coneflower, and Schweinitz's sunflower typically require open habitat conditions along with basic soils. Habitat conditions within the project sbxdy area that provide potential suitable habitat include utility rights-of-way, road shoulders, and other areas that are maintained in an open condition. Eight areas were identified as potential suitable habitat based on soils mapping in conjunction with aerial photography. These potential suitable habitat areas ("priority habitat areas'� are shown on Figure 2a. Following the identification and mapping of potential suitable habitats ("priority habitat areas'�, qualified biologists from KHA conducted field surveys far the federally listed endangered plant species during the weeks of October 17 and 24, 2005. Biologists methodically walked transects to ensure total coverage of the potentially suitable habitat areas. Spacing between transects was maintained at approximately 25 to 50 feet, depending on vegetative cover. Forested edges surrounding potentially suitable habitat areas were surveyed independently to ensure these areas were covered sufficiently. 3.2 Survey Segment 2— Gaston County Priar to the initiation of the field investigation and as part of the scoping process, ESI identified potential suitable habitat (called "high probability areas" in ESPs report) for Schweinitz's sunflower using aerial photography. Potential suitable habitat included roadsides, powerline rights-of-way, field edges, trails, and other open, disturbed areas that were mapped on one of the above mentioned soil types where Schweinitz's sunflower is typically found (Figure 3b). Maintained residential yards and fenced/maintained pastures with livestock were not considered to be potential suitable habitat areas, and therefore were not surveyed far the presence/absence of Schweinitz's sunflower. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary March 2006 Priar to conducting the survey, ESI biologists conducted a review of NC Natural Heritage Program (NHP) records (October 6, 2005) to deterxnine if Schweinitz's sunflower has been documented in the study corridor. No known occurrences of Schweinitz's sunflower have been documented within Survey Segxnent 2. The nearest documented occurrence of Schweinitz's sunflower is located approximately 4,000 feet south of the southern corridor, west of Catawba Creek and north of SR 2650. ESI biologists also reviewed the Latta Plantation (Mecklenburg County) reference population of Schweinitz's sunflower on October 10 and 17, 2005 to confirm the flowering status. ESI biologists noted that the reference population was past its peak flowering period and only a few flowers remained. The surveys were conducted based on the presence of seed heads and vegetative characteristics. Surveys in Segment 2 were conducted by ESI biologists on October 10-12, 17-20, and 25, 2005. ESI biologists visually surveyed field edges and roadsides. Powerline rights-of-way and other large areas were surveyed by walking transects through potentially suitable habitat. 3.3 Survey Segment 3— Gaston County Aerial photographs and soils mapping were used to aid in identification of potential suitable habitat areas (called high priority areas and medium priority areas in HW Lochner's repart) such as clearings and edges of upland woods (Figure 3c). Cleared areas with Cecil, Gaston, Tatum, and Uwharrie soil types were considered potential suitable habitat. A brief drive through of the project area confirmed the location and extent of potential suitable habitat areas. All areas to be surveyed were noted on base mapping. Potential suitable habitat areas were systematically surveyed by walking overlapping transects. Priar to conducting habitat assessments for Schweinitz's sunflower within the project study area, a known population of the species in bloom was visited along an abandoned railroad track in Charlotte, NC on October 10, 2005. This provided an opportunity to see the sunflower's flowering status prior to conducting formal surveys within the region. Surveys were conducted by Lochner biologists trained in identification of this species between October 10 and 18, 2005. 3.4 Survey Segment 4— Gaston County Aerial photos provided by NCDOT, USGS 7.5 minute quadrangles, and soil mapping were used to identify potential suitable habitat (called potential suitable habitat in Earth Tech's report) within the study corridar to search for Schweinitz's sunflower. Field maps were produced on 11 x 17 sheets at 1:12,000 scale. Areas containing power line, telephone, and gas line rights-of-way; road sides; and fields that were visible on mapping, were identified as potential habitat. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 6 March 2006 Additional habitat not readily visible from the existing mapping was identified by driving the search area. All potential areas having suitable habitat were walked and/or visually surveyed for Schweinitz's sunflower. Additionally, many areas initially identified as potential habitat were walked and a deterxnination made that they were not acbxally suitable. For purposes of Segxnent 4, the following definitions are used: Potential Habitat— An area from review of photos and mapping that appears to contain sunflower habitat Potential Suitable Habitat (called Priority Sunflower Habitat in Earth Tech's report) — Potential habitat, that upon field evaluation, appear to be suitable far the sunflower. Many areas initially identified as potential habitat are not suitable habitat due to disbxrbance, landscape position, or other factors (Figure 3d). On October 13, 2005, priar to the field search, the Natural Heritage Program Plants Database was searched for the occurrence of known populations and previous sightings around and within the search area. A known population of the sunflower was observed on October 17 in preparation to identify the species. This population is located in a power line right-of-way corridor in Asheboro, North Carolina along NC 42 about one-half mile south of US 64. Field surveys far this species were conducted by Earth Tech biologists October 18 - 20, 2005. A targeted survey approach was used, searching only for Schweinitz's sunflower. Within each community surveyed, a random meander technique was used to visually search for sunflower plants. Search intensity varied within each community, depending upon topography, bordering communities, observed land use patterns (both past and current), and plant species observed within the community. 4.0 Statement of Qualifications of Investigators 4.1 Survey Segment 1— Mecklenburg County — KHA Investigator: Norton Webster, Environmental Scientist Education: BS, Business, Wake Forest University MS, Forestry, North Carolina State University Experience: Kimley-Horn and Associates, Inc., December 2000 to present Environxnental Scientist, ARCADIS, Inc., July 1998 to December 2000 Expertise: Wetland/Stream Delineation, Perxnitting, Threatened and Endangered Species Surveys U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 7 March 2006 Investigator: Tommy Cousins, Environxnental Scientist Education: BS, Environxnental Science, North Carolina State University Experience: Kimley-Horn and Associates, Inc., January 2003 to present Expertise: Threatened and Endangered Species Surveys, GPS/Geographic Information Systems, Wetland/Stream Delineation Investigator: Tyler McEwen, Environmental Scientist Education: BS, Environxnental Science, North Carolina State University Experience: Kimley-Horn and Associates, Inc., March 2005 to present Environxnental Scientist, Environxnental Services, Inc., January 2003 to March 2005 Expertise: Threatened and Endangered Species Surveys, GPS, Wetland/Stream Delineation, Geographic Information Systems 4.2 Survey Segment 2— Gaston County — ESI Investigator: Education Experience Expertise Investigator: Education Experience Gail Tyner BS North Carolina State University 8+ years of Professional Experience Nabxral resource investigations, wetlands delineation, wetland mitigation monitoring, threatened and endangered species surveys including red-cockaded woodpecker, rough-leaved loosestrife, and Schweinitz's sunflower.

The Survey Segxnent 1 area also includes limited small agricultural areas, a tree farxn, and industrial areas, as well as the I-485 corridor. The project study area is bound on the western side by the Catawba River (Lake Wylie). I-485 transects the eastern side of the project study area, running north to south. A transmission line corridor crosses the Catawba River and traverses the western and southern portions of Survey Segment 1(see Figure 2a). U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 10 March 2006 The potential suitable habitat areas ("priority habitat areas'� were intensively surveyed. None of the three protected species were found during the field surveys. 5.2 Survey Segment 2— Gaston County The potential suitable habitat areas within Survey Segxnent 2 were surveyed far the presence/absence of Schweinitz's sunflower. (Figure 2b) One population of Helianthus schweinitzii was observed within the project study area, and is shown on Figure 3. This population is located on the northern edge of the northern Detailed Study Corridor, south of Catawba Creek, along the western side of SR 2435 (Union-New Hope Road). On October 25, 2005, the Schweinitz's sunflower population was verified by Senior Project Manager Kevin Markham. Other sunflowers commonly observed within the project study area included small- headed sunflower (Helianthus microcephalus), hairy sunflower (Helianthus hirsutus), and spreading sunflower (Helianthus divaricatus). According to the FZora of the Carolinas and Virginia, both the small-headed sunflower and the spreading sunflower are common throughout the Piedmont region of North Carolina. The hairy sunflower is uncommon in North Carolina and is on the Virginia Watch List 5.3 Survey Segment 3— Gaston County No Schweinitz's sunflowers were found in Survey Segxnent 3. Another Helianthus species that had already bloomed was observed. The species was deterxnined to most likely be roughleaf sunflower (Helianthus strumosus). Other common plant species include fescue (Festuca sp.), daisy fleabane (Erigeron annuus), white wood aster (Aster divaricatus), stiff aster (Aster linariifolius), blackberry (Rubus sp.), dog fennel (Eupatorium capillifolium), and several types of goldenrods (Solidago spp.). 5.4 Survey Segment 4— Gaston County All potential suitable habitat areas were investigated for Schweinitz's sunflower and none were found. The late survey date resulted in many of the local fall blooming perennial and annual plants, including Schweinitz's sunflower, being past peak flowering. Typically, only the distinctive seed head remained. Vegetative growth on the plants within the reference population observed was still green, but they had lost vigor, with lower leaves withered or dead. Identification of the sunflower relied upon the visibility of seed heads, growth pattern of the plant, and identification of other vegetative characteristics that make it distinctive. Most of the area within the search limits is urbanized with only a few limited areas containing relatively natural communities. These areas are typically forested and often surrounded by urban communities. The general community types searched includes utility rights-of-way, fields, and road sides. Many of these communities are located in unsuitable landscape positions along lower slopes, toe slopes, and floodplains and do not provide suitable habitat. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 11 March 2006 The utility rights-of-way identified from mapping are mostly power lines. One gas utility crosses the project area, and sewer lines are located along stream floodplains. The gas utility is closely mowed within Survey Segment 4. Most sewer lines were not searched because of their low topographic position along streams. The typical community within the power line rights-of-way is early successional and consists of mostly annual and perennial herbaceous species with limited woody species. The woody species present are often root sprouts, with a larger main stem or stems nearby that are dead. Along the edges of many of the power line rights-of-way was a band where all woody vegetation and most of the herbaceous vegetation was recently sprayed. The herbaceous vegetation included Canada goldenrod (Solidago canadensis), beggar lice (Bidens sp.), hairy white oldfield aster (Symphyotrichum pilosum), dog fennel (Eupatorium capillifolium), broomsedge bluestem (Andropogon virginicus), blackberry (Rubus sp.), and wingstem (�erbesina alternifolia). No Schweinitz's sunflower plants were found within the utility rights-of-way. The existing community composition along the road sides is variable, depending on the level of maintenance. The extent of maintenance appeared to differ depending on the width of the road cuUfill, surrounding land use, and designated traffic level. All roadsides have been mowed to some extent. Power lines often parallel the roads. Much of the vegetative community along the roads is similar to the utility rights-of-way, although exotic invasive species are more dominant. Areas having herbicide application were also observed along the roads. In general, roadsides communities appear well maintained. No Schweinitz's sunflower plants were found within the road side community. The fields identified consisted of either actively cultivated fields, active pasture, or old abandoned fields in various stages of successional growth. For the most part, actively managed field edges appear to be either clear of all weedy vegetation or fighting encroachxnent of Japanese honeysuckle (Lonicera japonica) or kudzu (Pueraria montana). Old field edges are typically heavily overgrown and the edges obscured with woody vegetation. Many fields were adjacent to forested communities or urban development. Relatively few field edges investigated contained suitable habitat for Schweinitz's sunflower. No Schweinitz's sunflower plants were found within the field edges. The remaining areas identified were associated with urban development. The developed urban areas are typically maintained landscapes lacking resemblance to natural communities. These areas are small home gardens, mowed lawns, landscaped borders, and waste areas. None of these areas contained suitable habitat for Schweinitz's sunflower. No Schweinitz's sunflower plants were found within the urban communities.

NCNHP records also did not indicate any species located within a mile of the study area. Based on the results of this survey and supporting documentation, the proposed Detailed Study Alternatives in Survey Segment 1 will not affect Michaux's sumac, Schweinitz's sunflower, or the smooth coneflower species. Michaux's Sumac BIOLOGICAL CONCLUSION NO EFFECT All potential suitable habitats for Michaux's sumac within Survey Segxnent 1 were surveyed. No populations of Michaux's sumac were found during this search. The NCNHP record for Michaux's sumac is historic and nearly all of the area has been developed, farxned, and otherwise negatively impacted for suitable habitat NCNHP records failed to document the location of any known populations of the sumac in or immediately adjacent to the study corridor. Based on the results of this survey, the project will not impact the Michaux's sumac within the area surveyed. Based on the results of this survey, the project will have no affect on the Michaux's sumac within the area surveyed. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 13 March 2006 Schweinitz's Sunflower BIOLOGICAL CONCLUSION NO EFFECT All potential suitable habitats for Schweinitz's sunflower, within the study corridor were surveyed. No populations of Schweinitz's sunflower were found during this search. The search area is farther west than other known locations and nearly all of the area has been developed, farmed, and otherwise negatively impacted for suitable habitat. NCNHP records failed to document the location of any known populations of the sunflower in or immediately adjacent to the study corridor. Based on the results of this survey, the project will not impact the Schweinitz's sunflower within the area surveyed. Based on the results of this survey, the project will have no affect on the Schweinitz's sunflower within the area surveyed. Smooth Coneflower BIOLOGICAL CONCLUSION NO EFFECT All potential suitable habitats for smooth coneflower, within the study corridor were surveyed. No populations of smooth coneflower were found during this search. The search area is not within a mile of other known locations and nearly all of the area has been developed, farxned, and otherwise negatively impacted for suitable habitat. NCNHP records failed to document the location of any known populations of the sunflower in or immediately adjacent to the study corridor. Based on the results of this survey, the project will not impact the smooth coneflower within the area surveyed. Based on the results of this survey, the project will have no affect on the smooth coneflower within the area surveyed. 6.2 Survey Segment 2— Gaston County Schweinitz's Sunflower BIOLOGICAL CONCLUSION May Affect/Not Likely to Adversely Affect The powerlines, roadsides and open areas within the project study area are high probability areas for potentially suitable Schweinitz's sunflower habitat. These high probability areas were surveyed for the presence/absence of Schweinitz's sunflower. One population of Helianthus schweinitzii was observed within the project study area. This population is located on the northern edge of the narthernmost Detailed Sbxdy Corridor, south of Catawba Creek along the western side of SR 2435 (Union-New Hope Road). Due to its location in relation to the Detailed Study Corridors, it is likely possible to avoid all impacts to the observed Schweinitz's sunflower population. 6.3 Survey Segment 3— Gaston County Schweinitz's Sunflower BIOLOGICAL CONCLUSION NO EFFECT Although potential suitable habitat areas are present within the project sbxdy area in the form of regularly maintained roadside shoulders, field or pasture edges, and utility easements, no U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary March 2006 14 individuals of the Helianthus schweinitzii species were observed during the October 2005 surveys. A North Carolina Natural Heritage Program element occurrence records search on October 14, 2005 revealed no element occurrences of this species within 1 mile of Survey Segxnent 3; however several current records of the species are located within a few miles southeast of Survey Segxnent 3. Therefore, it can be concluded that Survey Segxnent 3 of the proposed project will have a Biological Conclusion of No Effect for Schweinitz's sunflower. 6.4 Survey Segment 4— Gaston County Schweinitz's Sunflower BIOLOGICAL CONCLUSION NO EFFECT All potential suitable habitat areas for Schweinitz's sunflower, within Survey Segxnent 4 were surveyed. No populations of Schweinitz's sunflower were found during this search. The search area is farther west than other known locations, and nearly all of the area has been developed, farmed, and otherwise negatively impacted for suitable habitat. Based on the results of this survey, the project will not impact the Schweinitz's sunflower within Survey Segxnent 4. Based on the results of this survey the project will have No Effect on the Schweinitz's sunflower within the area surveyed. 7.0 State-Listed Species Survey Segments 1-3 Surveys for state-listed species were not requested as part of the protected species scope. A review of NHP files indicated that no state-listed species have been documented within or adjacentto Survey Segxnents 1-3 ofthe Detailed Study Alternatives. No directed surveys were conducted for any species other than those listed by the USFWS as Endangered for Mecklenburg or Gaston Counties. Survey Segment 4 During the survey, an unrecorded population of Georgia aster (Symphyotrichum georgianum or Aster georgianus) was discovered in a power line right of way. The Georgia aster is State listed as Threatened. It is listed as Cl by the US Fish and Wildlife Service, which does not provide it any special protection but indicates that it is under consideration for official listing and there is sufficient inforxnation to support listing. Therefore, this species may be listed for federal protection in the fubxre. U-3321 Gastan County East-WestConnector Protected PlantSpecies Surveys Summary 15 March 2006 8.0 Conclusions Protected plant species surveys were conducted along the Gaston County East-West Connector Detailed Study Corridors in September through October 2005. The surveys were for protected plant species listed as Threatened or Endangered by the US Fish and Wildlife Service (USFWS) that have ranges which extend into Gaston ar Mecklenburg Counties. Far Mecklenburg County, there are three plant species listed as endangered: Michaux's sumac (Rhus michauxii), smooth coneflower (Echinacea laevigata), and Schweinitz's sunflower (Helianthus schweinitzii). None of the three protected plant species were found within the Detailed Study Corridors (Segxnent 1) during the field surveys. Therefore, the biological conclusion for each of the three species is `no effecY. For Gaston County, there is one plant species listed as endangered, Schweinitz's sunflower (Helianthus schweinitzii). One population of this protected plant species was found in the Detailed Study Corridor area along Union New Hope Road between NC 279 and NC 274. This population was located on the northern edge of the northernmost corridor. Due to its location in relation to the Detailed Sbxdy Corridors, it is likely possible to avoid all impacts to the observed Schweinitz's sunflower population. The biological conclusion for the Schweinitz sunflower is "may affecUnot likely to adversely effecY' far the Detailed Sbxdy Corridor area in Gaston County along Union New Hope Road. For other Detailed Study Corridor areas in Gaston County, the biological conclusion is "no effect." Any activity perxnitted, funded or conducted by a federal agency that may affect a listed species or designated critical habitat requires a consultation with the USFWS. The result of the consultation is a written biological opinion of whether the proposed action is likely to result in jeopardy to a listed species or adverse modification of designated critical habitat.
