The North Carolina Turnpike Authority proposes to improve east west travel between 185 west
of Gastonia in Gaston County and I 485/NC 160 in Mecklenburg County The Gaston East West
Connector is designated as TIP Project No U 3321 in the NCDOT s 2007 2013 Transportation
Improvement Program (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 1 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
12 Project Alternatives
There are sixteen new location Detailed Study Alternatives (DSA) under consideration for the
proposed project The corridor segments comprising these sixteen DSAs are shown in Table 1
and on Figure 2

Water resource information was obtained from publications posted on the World Wide Web by
NCDENR Division of Water Quality (DWQ) Information concerning the occurrence of
federally protected species in the study 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 Information 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 2007) 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 for 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 US Army Corps of Engineers Wetlands
Delineation Manual (Environmental 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 Lespmasse was the NCDWQ representative that performed
the field verifications No written confirmation or verification has been issued by the US
Army 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 performed 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
nomenclature follows the National Plant Data Center PLANTS Database (USDA NRCS 2006)
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

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
21 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 of Mecklenburg County North Carolina
(USDA 1980)
21 1 Soil Associations
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 project study 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 northwestern 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
1 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

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 12 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 information 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 The following provides descriptions

Numerous unnamed perennial and intermittent tributaries are also present in the project study
area 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 Fork 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 Fork 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 (HQW) Water Supplies (WS I or WS II) or
Outstanding Resource Waters (ORW) occur within 10 miles (1 6 km) of the project study area
2 2 3 Water Quality
This section describes the quality of the water resources within the project study 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 agricultural production (largely hay) A large proportion of the watershed is
moderately developed as residential or industrial Many of the waterways and wetlands within

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
Bann wide water quality assessments are conducted by the Environmental Sciences Branch
Water Quality Section of the DWQ The program has established monitoring stations for
sampling selected benthic macro invertebrates 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 Poor 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 York 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 macro invertebrate monitoring site were
sampled from Catawba River Subbasm 30837 in 2002 The benthic macro invertebrate
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) permitted dischargers within the sites
watershed with a combined discharge of 102 MGD (NCDENR 2003)
A fish sampling site on Catawba Creek rated good Fair in 1997 but dropped to Fair in 2002
Three small NPDES permitted 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 3 Impaired Waters
The North Carolina Water Quality Assessment and Impaired Waters List (NCDENR 2006b) is an
integrated report that includes both the 305(b) and 303(d) reports 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) reports 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

impaired waterbodies that is derived from the 305(b) report/Use Support 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 Environmental 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 impairment 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 Point Source Discharge Permits
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 permitted discharges into streams in the project
study area They are listed in Table 4 below

2 2 3 5 Non Point Source Discharge
Unlike pollution from industrial and sewage treatment non point source (NPS) pollution comes
from many non discrete sources 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 harmful 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 Atmospheric 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 for the National Marine Fisheries
Service (NMFS) regional fishery management councils (FMC) and other Federal agencies to
identify and protect important marine and anadromous fish habitat These amendments
established procedures for the identification of Essential Fish Habitat (EFH) 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
estuarine waters therefore there will be no EFH impacts associated with this project
2 2 4 Summary of Anticipated Impacts
14
February 2008

Natural Resources Technical Report
Gaston East West Connector Gaston and Mecklenburg Counties North Carolina
1 Both temporary and permanent impacts to the water quality of the project study area will occur
from the project Potential short term 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
0 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
containment 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
30 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 (ICEQ Terrestrial Vegetation of the
Southeastern United States ( Weakley et al 1998) (NatureServe 2006) 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 nomenclature 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

February 2008

Natural Resources Technical 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 4W) 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 alignment but
may not be mentioned separately for each community
3 11 Disturbed Community
The majority of the terrestrial communities found in the project study 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 vtrgtnicus) fescue (Festuca sp ) Japanese
honeysuckle (Lomcera japontca) 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 Agricultural Land
This community is not a natural 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 network of
pastures (Figure 4A)
313 Clearcut
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 amertcana) fireweed (Erechtttes
hteractfolia) broomsedge and asters Many tree and shrub seedlings begin to sprout following a
clearing and common species include red maple sweetgum (Ltqutdambar styractflua) tulip
poplar (Ltrtodendron tulipifera) shortleaf pine (Pinus echtnata) and loblolly pine (Ptnus taeda)
A representative example of this community type is located east of Homewood Drive and South
of Linwood Road SR 1133 (Figure 4D)

3 14 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) or Mesic Mixed Hardwood Forest
(Natureserve community Piedmont Acidic Mesic Mixed Hardwood Forest CEGL008465) in
upland areas and piedmont /mountain bottomland forest in floodplains that are adjacent to larger
stream channels The piedmont/mountain 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 virgimana) 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 (Vaccamum sp ) and strawberry bush (Euonymus americana) Herbaceous vegetation
is usually sparse although it can be locally diverse and includes crane fly orchid (Tipulana
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 15 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 acrosticholdes) wild ginger (Hexastylis artfolia) and lions 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 Natureserve equivalent
of this forest is most likely a Piedmont Acidic Mesic Mixed Hardwood Forest (CEGL008465)
3 16 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

Natut al Resources Technical 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 shortleaf
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 Natureserve A representative example
of this community type is located between Double Oaks Road and Dorchester Road SR 3076
(Figure 4M)
3 1 7 Pine Forest
Scattered throughout the project are pine forests that appear associated with abandoned
agricultural land unmanaged clearcuts and unmamtamed pine plantations This community is
differentiated from pine plantations in that they are not heavily managed for 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 mature 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)

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 halim folia) A dense
group of this community type is located southwest of Exit 13 on I 85 along a powerline right of
way (Figure 4A)
3 110 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 opportunistic and
capable of surviving on a variety of resources ranging from vegetation to both living and dead
faunal components Fauna or 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
(Dtdelphis virginiana) are true opportunists 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 turkey 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 virgimanus) 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 days (Cyanocitta
cristata) northern bobwhite (Colinus virgintanus) eastern towhee (Pipilo erythrophthalmus)
song sparrows (Melospiza melodia) Carolina chickadees (Poecde carohnensts) white throated
sparrows (Zonotrichia albtcollis) and bluebirds (Scalia sialas) are likely species that occur in the
project study 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 (Strix varia) prefer forested
riparian areas while neotropical migrant species such as the ovenbird (Seturus aurocapolus)
wood thrush (Hylocichla mustelina) and Acadian flycatcher (Empidonax virescens) prefer the
upland woods In the leaf litter of the forested habitats the southern short tailed shrew (Blarina
caroltnensis) and the white footed mouse (Peromyscus leucopus) may be found Gray squirrels*
(Sciurus carohnensis) 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 lateralts) may also be found in forested communities Forested wetlands

32 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 intermittent 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 study 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 to 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 study area are designated as warmwater habitats by the NC Division of Water
Quality (NCEEP 2007) Based on range maps in Menhmtck (1991) it can be presumed that the
following fish species occur in project study area streams redbreast sunfish (Lepomts aurztus)
bluegill* (Lepomas macrochirus) largemouth bass (Micropterus salmotdes) rosystde
dace *(Clinostomus fundulocdes) eastern mosquttofish (Gambusta holbrookt) bluehead chub
(Nocomis leptocephalus) greenfin shiner (Notropzs 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 cirrzgera) dusky salamander* (Desmognathus
fuscus) and green frogs* (Rana clamttans) Asiatic clams* (Corbicula flumcnea) were a very
common exotic mollusk species in project streams
Additionally numerous farm 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
(Gambusza 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 mgromaculatus) white crappie (Poxomis annularis) white perch (Morone amertcana)
blue catfish (Ictalurus furcatus) and channel catfish
33 Summary of Anticipated Impacts
Project construction will have various impacts to the previously described terrestrial and aquatic
communities Any construction activities to or near these resources have the potential to impact
biological functions This section quantifies and qualifies potential impacts to the natural
communities within the project study area in terms 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

Destruction of natural communities along the project alignment will result in the loss of foraging
and breeding habitats for the various animal species that utilize the area 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 Efforts should be made to ensure that no
sediment leaves the construction site
rIndirect impacts will occur from forest fragmentation Forest fragmentation occurs when large
contiguous forests are divided into smaller patches by urbanization roads and agriculture This
process reduces the forest s 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
February 2008
21

Natural Resources Technical 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
fragmented 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 temperature 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 Best Management Practices for Protection of Surface Waters
40 JURISDICTIONAL TOPICS
This section provides inventories and impact analyses for two federal and state regulatory issues
Waters of the United States and federally protected species
41 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 Army Corps of Engineers ( USACE) Any
action that proposes to dredge or place fill material into surface waters or wetlands falls under
these provisions
4 1 1 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 Lespmasse was the NCDWQ representative that performed the field
verifications No written confirmation or verification has been issued by the US Army Corps of

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 7/25/07) 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 judgment A table listing each wetland the DWQ
rating and wetland type (Cowardm 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

The following provides a general description of each wetland type
PEM1 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 rush (Juncus effusus) bulrush (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 (Salix mgra) 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 permanently flooded (PEM1F) intermittently exposed (PEM1G) and intermittently flooded
(PEM1J) A good example of this wetland type is Wetland 159

PF01 These are palustrme 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 (Liquidambar styractflua) willow oak (Quercus phellos) tulip poplar (Liriodendron
tulipifera) spicebush (Lindera benzoin) downy arrowwood (Viburnum dentatum) Chinese privet
(Ligustrum smense) 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 (PFOIA)
saturated (PFO1B) seasonally flooded (PFO1C) a combination of seasonally flooded or
saturated (PFOIE) semi permanently flooded (PFO1F) intermittently exposed (PFO1G) and
intermittently flooded (PFO1J) A good example of this wetland type is Wetland 34
PSS1 These are palustrme 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 (PSS1C) and semi permanently flooded (PSS1F) A good example of this wetland type
is Wetland 189
PSS3C These are palustrme 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 palustrme wetlands with unconsolidated bottoms and are permanently
flooded due to dikes or impoundments These are farm ponds or other types of manmade 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 determine intermittent and perennial status
Appendix G contains the USACE Stream Quality Assessment Worksheet 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 term the waters of the U S in Rapanos v US and in Carabell v US
(hereafter referred to as Rapanos) The decision provided two new analytical standards for
determining 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 berm dike or similar feature) a relatively permanent
water body (RPW) or (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
February 2008

Natural Resources Technical Report
Gaston East West Connector Gaston and Mecklenburg Counties North Carolina
Budget (OMB) and the Presidents Council on Environmental Quality (CEQ) developed the
Memorandum Regarding Clean Water Act Jurisdiction Following 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 Almost all wetlands that were adjacent (nearby but not directly abutting
a stream) were determined 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

4 1 2 Catawba River Riparian Buffer Rules
Permanent riparian buffer protection rules were enacted for the main stem of the Catawba River
below Lake James to The NC /SC border (NCDWQ 2004) These rules also encompass the seven
mainstem lakes from Lake James to the NC /SC 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 2 landward 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 segments that are flooded due to the presence
of Lake Wylie and are Catawba Creek South Fork Catawba River and the Catawba River
Catawba Creek only occurs on the southern half of the southernmost alternative segment and
has potential to be avoided during the alternatives analysis
4 1 3 Summary of Anticipated Impacts
Project construction 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 construction Table 7 presents the amount of streams and
wetlands that could be potentially impacted by each alternative Impacts are based upon the
1 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

42 Permit Issues
Impacts to jurisdictional surface waters and protected Catawba River riparian buffers are
anticipated from the proposed project Permits and certifications from various state and federal
agencies will be required prior to construction activities
4 2 1 Required Permits
Stream and wetland impacts will likely exceed the limits allowable under the USACE Nationwide
Permit program Therefore it will be necessary to submit an Individual 404 Permit application to
the USACE for stream and wetland impacts
This project will also require a 401 Water Quality Certification from the NCDENR prior to
issuance of the Individual 404 Permit Section 401 of the CWA requires that the state issue or
deny water certification for any federally permitted or licensed activity that results in a discharge
into Waters of the United States Final permit 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 for 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
February 2008
26

4 2 2 3 Compensation
Compensatory mitigation is not normally 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 (t e compensatory
on site mitigation) There are many possible streams in the project study 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
Furthermore 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 environmental regulatory agencies will ultimately
provide final permit and compensatory mitigation decisions for 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

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 Environmental Protection Agency (EPA) and
USACE in determining 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 permit 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 median 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 for the protection of surface
waters and wetlands
• Reduction of clearing and grubbing activity in and adjacent to water bodies
• Judicious pesticide and herbicide usage

Bald eagle (Halmeetus leucocephalus)
Family Accipitridae
Date First Listed March 11 1967

Natural Resources Technical Repoi t
Gaston East West Connector Gaston and Mecklenbui c 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 performed 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 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
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 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 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

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 muhlenbergu)
Vertebrate Family Emydidae
Federally Listed 1997
Threatened (Similarity of Appearance) I
The bog turtle is a small freshwater turtle reaching a maximum carapace length of 114 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— colored starburst pattern The plastron is brownish black with
contrasting yellow or cream areas along the midlme 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 intermediate stage of succession During the winter this species
hibernates dust 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 for this species in the project study area Numerous emergent and shrub
scrub wetlands that may be suitable for the species exist in the project study area Suitability of
these wetlands as bog turtle 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 for the bog turtle have been performed The
following emergent wetlands were identified as potential habitat for bog turtles 1 8 19 25 31

approximately 4 3 miles northeast of the project study area
Carolina heelsplitter (Lasmigona decorata) Endangered
Invertebrate Family Uniomdae
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 156 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 report 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
A survey for freshwater mussels took place on Septembe r
biologists Biologists looked at 28 streams that could b e

can be found in Appendix A
Because freshwater mussels were not found in any of the surveyed streams it is concluded that
the Carolina Heelsplrtter 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

Michaux's sumac (Rhus michauxii) Endangered
Family Anacardtaceae
Federally Listed 1989
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 plants 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 for this species is good for two years The
report documenting the 2005 survey can be found in Appendix A
Schweinitz's sunflower (Hehanthus schweinitzit) Endangered
Plant Family Asteraceae
Date Listed 5 7 91
Schwemitz 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
Schwemitz 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 leaf From September to frost
Schwemitz 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

Natural Resources Technical 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 Affect/ Not Likely to Adversely Affect
The powerlines roadsides and open areas within the project study area are high probability areas
for potentially suitable Schweinrtz s sunflower habitat These high probability areas were
surveyed for the presence /absence of Schweinitz s sunflower in 2005 One population of
Helianthus schweinitzil was observed within the project study area This population is located on
the northern edge of the northernmost Detailed Study Corridor south of Catawba Creek along the
western side of SR 2435 (Union New Hope Road) (Figure 5) 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 2006) 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 northeast 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 4 9 feet (1 5 m) tall 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 structures) are light pink to purplish usually drooping and 1 9 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
February 2008

Natural Resources Technical 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 mayor 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 for the smooth coneflower is present in the project study 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

MEMORANDUM TO Derrick Weaver P E Group Head
Consulting Engineering Group
FROM Jared Gray Environmental Biologist
Office of the Natural Environment
SUBJECT Protected species survey report for the Carolina Heelsplitter
(Lasmigona decorata) for the proposed Gaston County East
West Connector in Gaston and Mecklenburg Counties Federal
Aid Project No STP 1213 (6) WBS Element 34922 1 1 TIP
Project No U 3321
The following memorandum addresses the Carolina Heelsplitter (Lasmigona decorata) a
federally protected species listed by the U S Fish and Wildlife Service for Cabarrus County The
habitat requirements for the Carolina Heelsplitter are shaded areas either in ponded portions of
streams or in runs along steep banks with moderate current (Bogan 2002) The more recent
habitat where the Carolina Heelsplitter has been found is sections of streams with bedrock with
perpendicular crevices with sand and gravel in between the crevices and with large buffers
associated with the stream This project was pre screened by Alderman Environmental Services
Wildlife Resources Commission and U S Fish and Wildlife Service and this area was
considered to have a low probability of containing mussels
' Surveys, Habitat and Methods
A mussel screening was conducted on September 15 16 2005 by NCDOT biologists
' Jason Mays Kathy Herring Mike Sanderson and Jared Gray NCDOT biologist Neil Medlin
Matt Haney and Jared Gray finished the screening on September 21 2005 NCDOT biologist
looked at twenty eight streams that could be potentially crossed by the proposed Gaston East
West Connector The results of the habitat assessments are in Table 1 of this report NCDOT
went to these thirty sites and based on what was observed conducted a typical mussel screening
(100 meters upstream and 400 meters downstream) or a habitat assessment Some streams did not
have water in them so a data sheet was completed with any pertinent information The following
paragraphs will cover the eight named streams that potentially could be crossed by the proposed
project and the results of those surveys All eight of these streams were surveyed using the typical
mussel screening protocols
The Oates Creek crossing at Oates Road (SR 1312) contains runs riffles and pool areas
' with normal substrate compactness The substrate at the crossing consists of silt sand cobble and

gravel with medium current Sand was the most dominant substrate in Oates Creek The portion
of the creek that was surveyed had a moderate stream buffer The stream banks had some erosion
and undercutting of its banks The land use was sub urban Oates Creek is shallow with 100
percent of the stream less than 2 feet deep Oates Creek was 2 0 meter wide and the bank heights
were 15 meters No freshwater mussels were found in 10 man hours of survey time
The second stream that was surveyed was Bessemer Branch The Bessemer Branch
crossing below 185 contains runs riffles pools and slack areas with normal substrate
compactness The substrate above and below the pipe consists of sand cobble and gravel with
slow to medium current Sand and gravel bars were present in Bessemer Branch Sand and gravel
were the dominant substrate in Bessemer Branch The portion of Bessemer Branch that was
surveyed had a moderate stream buffer The stream banks had some erosion and undercutting
present The land use was natural Bessemer Branch is shallow with 99 percent of the stream less
than 2 feet deep Bessemer Branch was 2 meters wide and bank heights were 15 meters No
freshwater mussels were found in 0 5 man hours of survey time
The next stream that was surveyed was Myrtle Creek The Myrtle Creek crossing at NC
29/NC74 contains runs riffles and pool areas with normal/unconsolidated substrate compactness
The substrate above and below the culvert crossing consists of silt sand and gravel with slow
current Silt and Sand were the dominant substrate in Myrtle Creek The portion of Myrtle Branch
that was surveyed had a narrow buffer by the road and moderate buffer downstream There were
junkyards adjacent to the road and the stream at this site and the stream banks closest to the
junkyard were highly erosive and unstable The land use was urban Myrtle Creek is very shallow
with 100 percent of the stream less than 2 feet deep Myrtle Creek was 175 meters wide and bank
heights were 2 5 meters No freshwater mussels were found in 0 5 man hours of survey time
Crowders Creek was the next stream that was surveyed The Crowders Creek crossing at
Archie Whitesides Road (SR 1122) contains riffles slack and pool areas with unconsolidated
substrate compactness The substrate above and below the bridge crossing consists of silt sand
pebble and gravel with slow /moderate current Silt and sand were the dominant substrate in
Crowders Creek The portion of Crowders creek that was surveyed had a narrow buffer
According to a landowner that has lived adjacent to Crowders Creek it ran blue when the dye
plant was open He also said when his cattle would get in the water to cool off their hair would
fall out and they would not drink the water The land use in the area was rural The stream banks
were unstable Crowders Creek is shallow with 95 percent of the stream less than 2 feet deep

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 Fork
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

MEMORANDUM
March 1 2007

Kevin Lapp Biologist Earth Tech
Bald Eagle Survey Report
The North Carolina Turnpike Authority is currently investigating alternatives associated with
development of a toll road facility on new location in Gaston and Mecklenburg Counties NC
The proposed Gaston County East West Connector (U 3321) around the city of Gastonia
includes 16 alternatives (endpoint to endpoint) which extend from south of the Charlotte Douglas
International Airport in western Mecklenburg County south of Gastonia to a link with Interstate
85 (1 85) dust west of Gastonia in Gaston County for a total of approximately 72 corridor miles
Corridor width for each alternative averages 1400 feet (Figure 1)
The following memorandum addresses surveys for the Bald Eagle (Haliaeetus leucocephalus) a
federally protected species listed by the U S Fish and Wildlife Service for Gaston and
Mecklenburg Counties performed as part of the environmental requirements associated with the
Gaston East West Connector project 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 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 In the southeast the nesting and breeding season runs from September to December
Bald eagles are known from Lake Wylie and the NC Wildlife Resources Commission (NCWRC)
and NC Natural Heritage Program ( NCNHP) each had data on separate bald eagle nest
locations An aerial survey of the Lake Wylie area within the project area and extending outward
one mile was performed 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 project 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 confirmed eagle nest was observed in a location that has been tracked by the NC Wildlife
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 Drive (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 (Hahaeetus leucocephalus) 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

12 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 segments 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 or Mecklenburg Counties
The four consultant groups and the survey segments are described below Each consultant
I
prepared a survey report for their respective segment as listed in the References Section of this
document

20 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
21 Plants Listed for Mecklenburg County
As of November 10 2005 the USFWS internet listing for Mecklenburg County identifies three
plant species listed as endangered Michaux s sumac (Rhus michauxii) smooth coneflower
(Echtnacea laevigata) and Schwemitz s sunflower (Helianthus schweinztzii) 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 for 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

Species Michaux s sumac (Rhus mzchauxu)
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 terminal 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 elliptic 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

Schwemrtz 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
Schwemrtz s sunflower from its relatives The upper surface of the leaves is rough with the
broad based spmose hairs directed toward the tip of the leaf From September to frost

30 Survey Methodologies
31 Survey Segment 1 - Mecklenburg County
The initial analysis (search) for the protected species began with a review of available mapping
Qualified biologists from KHA reviewed available aerial photography soils mapping and
corridor mapping to determine potential habitat areas deemed suitable for survey for 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 confirm 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 study 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 for 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
32 Survey Segment 2 — Gaston County
Prior to the initiation of the field investigation and as part of the scopmg process ESI identified
potential suitable habitat (called high probability areas in ESI s 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 for the presence /absence of
Schweinitz s sunflower
U 3321 Gaston County East West Connector
Protected Plant Species Surveys Summary 5
March 2006

Prior to conducting the survey ESI biologists conducted a review of NC Natural Heritage
Program (NHP) records (October 6 2005) to determine if Schwemrtz s sunflower has been
documented in the study corridor No known occurrences of Schwemrtz s sunflower have been
documented within Survey Segment 2 The nearest documented occurrence of Schwemrtz 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
Schwemrtz 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 Powerlme rights of way and other
large areas were surveyed by walking transects through potentially suitable habitat
33 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 report) 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
Prior to conducting habitat assessments for Schwemrtz 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
34 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 corridor to search for Schwemrtz 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 Gaston County East West Connector
Protected Plant Species 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
Schwemitz s sunflower Additionally many areas initially identified as potential habitat were
walked and a determination made that they were not actually suitable For purposes of Segment
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 for the sunflower Many areas initially
identified as potential habitat are not suitable habitat due to disturbance landscape position or
other factors (Figure 3d)
On October 13 2005 prior 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 for this species were conducted by Earth Tech biologists October 18 20 2005 A
targeted survey approach was used searching only for Schweimtz 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

The P otential suitable habitat areas ( priority habitat areas ) were intensively surveyed None of
the three protected species were found during the field surveys
52 Survey Segment 2 — Gaston County
I, The potential suitable habitat areas within Survey Segment 2 were surveyed for the
presence /absence of Schwemitz s sunflower (Figure 2b) One population of Hehanthus
schweinazu 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 ( Helanthus microcephalus) harry sunflower ( Helanthus hirsutus) and
spreading sunflower (Hehanthus divaricatus) According to the Flora 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
53 Survey Segment 3 — Gaston County
No Schweinitz s sunflowers were found in Survey Segment 3 Another Hehanthus species that
had already bloomed was observed The species was determined to most likely be roughleaf
sunflower ( Hehanthus strumosus) Other common plant species include fescue (Festuca sp )
daisy fleabane (Erigeron annuus) white wood aster (Aster divaricatus) stiff aster (Aster
linarufolius) blackberry (Rubus sp ) dog fennel (Eupatorium capilhfohum) and several types of
goldenrods (Sohdago spp )
54 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 Gaston County East West Connector
Protected Plant Species 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 (Soltdago canadensis) beggar lice (Bidens
sp ) hairy white oldfield aster (Symphyotrichum pilosum) dog fennel (Eupatorium capill folium)
broomsedge bluestem (Andropogon virgtntcus) blackberry (Rubus sp ) and wingstem (Verbesma
alternfolta) 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
cut/fill 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

Protected Plant Species Surveys Summary
March 2006

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 encroachment of Japanese
honeysuckle (Lonicerayapontca) or kudzu (Puerarta 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 Schwemitz 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

61 Survey Segment 1— Mecklenburg County
No Michaux s sumac Schweinitz s sunflower or smooth coneflower were found within Survey
Segment 1 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 Segment 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 farmed 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

Schweinrtz'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 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 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
62 Survey Segment 2 — Gaston County
Schwemitz's Sunflower
BIOLOGICAL CONCLUSION May Affect/Not Likely to Adversely Affect
The powerlmes 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 Hehanthus
schweimtzu was observed within the project study area This population is located on the
northern edge of the northernmost Detailed Study 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
63 Survey Segment 3 — Gaston County
Schweinitz's Sunflower
BIOLOGICAL CONCLUSION NO EFFECT
Although potential suitable habitat areas are present within the project study area in the form of
regularly maintained roadside shoulders field or pasture edges and utility easements no
U 3321 Gaston County East West Connector
Protected Plant Species Surveys Summary 14
March 2006

individuals of the Hehanthus 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 Segment 3
however several current records of the species are located within a few miles southeast of Survey
Segment 3 Therefore it can be concluded that Survey Segment 3 of the proposed project will
have a Biological Conclusion of No Effect for Schweinitz s sunflower
64 Survey Segment 4 — Gaston County
Schweinitz's Sunflower
BIOLOGICAL CONCLUSION NO EFFECT
All potential suitable habitat areas for Schweinitz s sunflower within Survey Segment 4 were
surveyed No populations of Schwemitz 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 Segment 4 Based
on the results of this survey the project will have No Effect on the Schweinitz s sunflower within
the area surveyed
70 State - Listed Species
Survey Segments 13
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
adjacent to Survey Segments 1 3 of the 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 C1 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 information to support listing Therefore this species may be listed for federal
protection in the future

80 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 or Mecklenburg Counties
For Mecklenburg County there are three plant species listed as endangered Michaux s sumac
(Rhus michauxtr) smooth coneflower (Echtnacea laevigata) and Schwemitz s sunflower
(Hehanthus schwetnazu) None of the three protected plant species were found within the
Detailed Study Corridors (Segment 1) during the field surveys Therefore the biological
conclusion for each of the three species is no effect
For Gaston County there is one plant species listed as endangered Schwemitz s sunflower
(Helianthus schweinitzaa) 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 Study Corridors it is likely possible to avoid all impacts to the observed
Schwemrtz s sunflower population The biological conclusion for the Schwemrtz sunflower is
may affect/not likely to adversely effect for the Detailed Study 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 permitted 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
