On behalf of the North Carolina Turnpike Authority (NCTA) Atkins is submitting an application for a
Section 404 permit and 401 Water Quality Certification for impacts to waters of the United States
including wetlands associated with the construction of the Gaston East West Connector The Gaston
East West Connector is a controlled access toll road on new location that extends from 185 west of
Gastonia to 1485 near the Charlotte Douglas International Airport in Mecklenburg County (Figures 1 and
2) The total length of the project is approximately 21 9 miles
The purpose of the Gaston East West Connector is to improve east west transportation mobility in the
area around the City of Gastonia between Gastonia and the Charlotte metropolitan area and particularly
to establish a direct access between the rapidly growing area of southeast Gaston County and western
Mecklenburg County This project purpose is based on the need to improve mobility access and
connectivity within southern Gaston County between southern Gaston County and western Mecklenburg
County the need to improve traffic flow on the sections of 185 US 29 74 and US 321 in the Project
Study Area and provide high speed safe reliable regional travel service along the 185 corridor
The Final Environmental Impact Statement for the Gaston East West Connector was issued on December
21 2010 (http //www ncdot gov/pro1ects/ ag rdenparkway ) The Record of Decision was issued on
February 29 2012
This application includes final design permit drawings for U 3321CB that extends from NC 279 (South
New Hope Road) in Gaston County to 1485 near the Charlotte Douglas International Airport in
Mecklenburg County and preliminary construction drawings for the U 3321AA U 3321B and U 3321CA
that extends from 185 west of Gastonia to NC 279 (Figure 1) Impacts to jurisdictional areas associated
with U 3321 CB that extends from NC 279 to 1485 are shown on Figures 4 15 through 4 22 and
Appendix 1 Final Design Permit Drawings This portion of the project will impact 077 acres of
wetlands 7 213 linear feet of streams (6 883 if permanent 330 if temporary) and 0 26 acre of open
waters (ponds) The preliminary construction drawings submitted for sections U 3321 AA U 3321B and
U 3321CA identify the jurisdictional areas and impacts within the construction limits of the final
alignment (Figures 4 1 through 4 14 and Appendix 1 — Preliminary Construction Drawings) In addition
jurisdictional areas that may be impacted within a 25 foot zone on either side of the construction limits
are shown Approximately 5 20 acres of wetlands 23 583 linear feet of streams and 2 86 acres of open
waters (ponds) may be impacted within the construction limits An additional 1 22 acres of wetlands
5 217 linear feet of streams and 0 90 acre of open waters (ponds) within the 25 foot zone on either side of

the construction limits may be impacted Total permanent impacts for the entire project will not exceed '
j 7 19 acres of wetlands 35 683 linear feet of streams and 4 02 acres of open waters (ponds) Impacts to
jurisdictional areas will occur within Cataloging Units 03050101 and 03050102 of the Catawba River
basin
As you are aware the NCTA is utilizing the design/build process to construct the Gaston East West
Connector The design build teams will be responsible for generating the final permit drawings for the
remainder of the alignment and will document the final alignment hydraulics and exact location and
amount of all impacts to jurisdictional areas Upon completion of final design by the design/build team a
permit modification request will be submitted to authorize unavoidable impacts for sections U 3321AA
U 3321B and U 3321CA The NCTA understands that impacts to jurisdictional areas outside of U
3321CB that extends from NC 279 (South New Hope Road) in Gaston County to I485 near the
Charlotte Douglas International Airport in Mecklenburg County are not to occur until permit '
modifications have been submitted and approved
As documented in the FEIS and this application the NCTA has avoided and minimized impacts to
jurisdictional areas to the maximum extent practicable through selection of the least environmentally
damaging practical alternative The NCTA is also committed to continuing the avoidance and
minimization of impacts to jurisdictional areas and protection of water quality through the design and
construction management phases of this project During construction the NCDOT Guidelines for the
Protection of Surface Waters /Sensitive Watersheds will be utilized throughout the project area
Compensatory mitigation for unavoidable impacts to jurisdictional areas will be provided through a
combination of on site stream and wetland mitigation and the Ecosystem Enhancement Program per the
terms of the Memorandum of Understanding between the U S Army Corps of Engineers N C
Department of Transportation and N C Department of Environment and Natural Resources
Atkins is available to provide you with additional information or arrange for a site visit if so desired

Attachment 2 BLOCK 15 — Location of Project
U 3321 Gaston East West Connector (Garden Parkway)
The Gastonia East/West Connector (Garden Parkway) is a controlled access toll road that extends from I
85 west of Gastonia Gaston County to 1 485 near the Charlotte Douglas International Airport in
Mecklenburg County (Figures 1 and 2) The total length of the project is approximately 21 9 miles The
U 3321CB section extends from the eastern terminus of the project at 1485 to NC 279 (South New Hope
Road) south of Cramerton (Figure 4 15 through Figure 4 22 and Appendix 1 Final Design Permit
Drawings) The remaining sections (U 3321 AA U 3321B and U 3321 CA) extend west from NC 279 to
185 west of Gastonia (Figure 1 through Figure 14 and Appendix 1 — Preliminary Construction
is Drawings) The latitude and longitude of each jurisdictional feature that will be impacted by this project
is provided in Table 3

Block 18 Nature of Activity

Attachment 3 BLOCK 18 — Nature of Activity
U 3321 Gaston East West Connector (Gai den Parkway)
The Gaston East West Connector (U 322 1) involves the construction of approximately 21 9 miles of
controlled access highway on new location in Gaston and Mecklenburg Counties and associated service
I� roads (approximately 2 75 miles) Activities that will be required for the construction of this facility
include clearing excavation and fill of wetlands and ponds and installation of culverts in streams
Final design permit drawings have been prepared for U 3321CB that extends from NC 279 (South New
Hope Road) in Gaston County to 1485 near the Charlotte Douglas International Airport in Mecklenburg
County Table 4 provides a summary of wetland and surface water impacts and the type of activity
proposed for each jurisdictional feature impacted in this portion of the project For the remainder of the
project extending from 185 west of Gastonia to NC 279 (U 3321 AA U 3321 B and U 3321 CA) the
amount of impact to Jurisdictional features based on preliminary construction drawings is provided for
each site within the construction limits of the final alignment In addition the amount of impact to
jurisdictional features that may be impacted within a 25 foot zone on each side of the construction limits
is provided
Tables 5 6 and 7 provide information concerning the type of waterbody specific activity and the
magnitude of the impact at each jurisdictional feature for the entire project alignment The location of the
impacts at each site is shown on the final design permit drawings and preliminary construction drawings
(Appendix 1)
Summary and Description of Riparian Buffer Impacts
Streamside npanan zones within the proposed corridor are protected under provisions of Catawba River
Basin Protection and Maintenance of Existing Riparian Buffers (15A NCAC 02B 0243) administered by
NCDWQ Streams and buffers within the proposed corridor that are subject to these rules include
Catawba Creek South Fork of the Catawba River and Catawba River A total of 82 878 square feet of
riparian buffer will be impacted at 3 separate locations (Table 8 Figures 4 15 4 16 and 4 18) The buffer
impacts are directly associated with the construction of bridges and are therefore allowable or
allowable with mitigation (15A NCAC 02B 0243(6) The impacts at Site 48 (Catawba Creek) are
associated with the construction of the bridge embankment and will result in the permanent removal of
25 577 square feet (0 59 acre) of riparian buffer therefore require mitigation (Figure 5) The magnitude of
the buffer impact at Site 48 is due to the bridge embankment required to support the badge that spans
Catawba Creek and associated wetlands and riparian buffer

U 3321 Gaston East West Connector (Garden Parkway)
Proiect Purpose
The proposed Gaston East West Connector also known as the Garden Parkway is a controlled access toll
road extending from 185 west of Gastonia in Gaston County to 1485 near the Charlotte Douglas
International Airport in Mecklenburg County (Figures 1 and 2) The total length of the project is
approximately 21 9 miles The project is included in the North Carolina Department of Transportation
( NCDOT) 2009 2015 State Transportation Improvement Program (STIP) as STIP Project U 3321 The
current NCDOT 2009 2015 STIP the 2035 Long Range Transportation Plan (LRTP) for the Gaston
Urban Area Metropolitan Planning Organization ( GUAMPO) and the 2035 LRTP for the Mecklenburg
Union MPO ( MUMPO) all include the project as a toll facility The GUAMPO and the MUMPO show in
their plans a new location roadway running through southern Gaston County and connecting over the
Catawba River to Mecklenburg County The Gaston East West Connector is a Strategic Highway
Corridor (SHC) The Gaston East West Connector is designated as a new freeway facility within the
Strategic Highway Corridors Vision Plan (SHCVP)
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 and particularly to establish
direct access between the rapidly growing area of southeast Gaston County and western Mecklenburg
County This project purpose is based on the following
• Need to improve mobility access and connectivity within southern Gaston County and between
southern Gaston County and Mecklenburg County
• Need to improve traffic flow on the sections of 185 US 29 74 and US 321 in the project study
area and improve high speed safe reliable regional travel service along the 185 corndor
Protect Need
The pnmary needs for the proposed action are summarized below
POOR CONNECTIVITY BETWEEN GASTON COUNTY AND MECKLENBURG COUNTY
AND WITHIN SOUTHERN GASTON COUNTY
• There are limited crossings of the Catawba River, constraining travel between and through
Gaston and Mecklenburg Counties The Catawba River separates Gaston and Mecklenburg
Counties and there are only four crossings of the river with none in the southern half of Gaston
County 185 and US 29 74 important as the only continuous east west through routes in Gaston
County provide parallel and adjacent crossings in the center of the county The next crossing of
the river south is about 1 1 miles away on NC 49 connecting York County South Carolina and
Mecklenburg County
185 is an important corridor for regional and longer distance travel About 70 percent of the
workers living in Gaston County who work in other counties go to work in Mecklenburg County
The Charlotte region is a mayor freight distnbution center and trucks use 185 to connect to
destinations to the southwest (e g Atlanta GA) west (e g Asheville NC) and northwest (e g
Hickory NC) Tourists from the Charlotte region traveling to the mountains of western North
Carolina and Tennessee also use 185 in Gaston County
• Projected growth in southern Gaston County and western Mecklenburg County will
continue to place demands on accessibility and connectivity between the two counties
According to the draft Gaston County Comprehensive Plan (Section 8 3 of the plan) southern
Page 1 of 3

Attachment 4 BLOCK 19 — Protect Purpose
U 3321 Gaston East West Connector (Garden Parkway)
Gaston County especially the southeastern portion is expected to experience high residential
growth in the next twenty years Similarly the Dixie Berryhill area a planned development area
in western Mecklenburg County west of the Charlotte Douglas International Airport is expected
to build out with high residential densities mixed with commercial uses and transit oriented
development
The Charlotte Douglas International Airport in western Mecklenburg County employs over
16 000 people and is expanding through construction of a third runway In the future the airport
also is planned to have an intermodal facility combining rail truck and air cargo transport that
would generate employment opportunities and substantial numbers of regional truck trips
The Dixie Berryhill Vision Plan calls for mixed use and transit oriented development in the
currently sparsely developed part of western Mecklenburg County directly across the Catawba
River from southeastern Gaston County This mixed use area will create more employment
opportunities in proximity to Gaston County in addition to existing office and industrial parks and
the Charlotte Douglas International Airport
South of 185 in Gaston County, a lack of connecting east west roadways makes travel
circuitous and limits mobility Currently there are no continuous east west routes in southern
Gaston County The roads in southern Gaston County generally run more north south For
example a person wishing to travel from the residential subdivisions on the Belmont peninsula
(the land between the South Fork Catawba River and Catawba River) to businesses and industries
along US 321 in southern Gaston County cannot do so directly they must first travel north to use
westbound 185 or US 29 74 to US 321 then south on US 321 or travel a circuitous route that
might include NC 273 (Armstrong Road) NC 279 (South New Hope Road) SR 2435 (Union
New Hope Road) NC 274 (Union Road) SR 2416 (Robinson Road) SR 2412 (Little Mountain
Road) SR 2420 (Forbes Road) to US 321
Visitors to the Daniel Stowe Botanical Garden (a large tourist attraction) must travel along
circuitous two lane non access controlled routes in southern Gaston County to reach the botanical
garden from the interstate and intrastate system This creates confusion and delays for visitors
most of whom (94 percent) are non members of the Daniel Stowe Botanical Garden During a
mayor event like the Fourth of July traffic entering the Daniel Stowe Botanical Garden has been
reported to back up on NC 279 (New Hope Road [SR 2302]) about 1 5 miles north of the site
Planned growth in southern Gaston County will result in an increase in the need for east
west mobility Between 1990 and 2000 southeastern Gaston County was the fastest growing
part of the county According to the Gaston County Comprehensive Plan the southeastern part of
the county is expected to continue to experience high residential growth through 2020
The Gaston Urban Area Metropolitan Planning Organization ( GUAMPO) and the
Mecklenburg Union MPO ( MUMPO) show in their plans a new location roadway through
southern Gaston County connecting over the Catawba River to Mecklenburg County In
their transportation plans the local MPOs recognize the need for a new freeway providing new
connectivity The GUAMPO ranks the proposed project as their top priority
The Gaston East West Connector is a Strategic Highway Corridor The Gaston East West
Connector is designated as a new freeway facility in the Strategic Highway Corridors Vision
Plan The primary purpose of the Strategic Highway Corridors initiative is to provide a safe

EXISTING AND PROJECTED POOR LEVELS OF SERVICE ON THE PROJECT AREA'S
MAJOR ROADWAYS
• Traffic volumes are protected to increase on 185, 1485, US 29 74, and US 321 in the study
area through 2030 Traffic volumes on the study area s mayor roadways are projected to
increase through 2030 On 185 traffic volumes are projected to increase 29 50 percent between
2006 and 2030 to 105 000 198 400 vehicles per day
• There are existing poor levels of service on segments of 185 in the study area Based on
2006 traffic volumes 185 is operating at a level of service (LOS) E or F from Exit 19 (NC 7
[Ozark Avenue]) through Exit 27 (NC 273 [Park Street]) in Gaston County
1 The LOS is defined with a letter designation from A to F with LOS A representing the best
operating conditions along a roadway or at an intersection and LOS F the worst
' • Future levels of service on 185, US 29 74, and US 321 are protected to worsen By 2030
185 is projected to operate at LOS E F throughout the study area (Exit 10 (US 29 74)) through
Exit 30 (I 485)) Congestion also is projected to increase on 1485 US 29 74 and US 321 US
29 74 is projected to operate at LOS F from McAdenville (Wesleyan Drive) east to 1485 a
distance of approximately 6 miles
• Congestion and incidents on 185 inhibit regional travel and the ability of 185 to function as
a Strategic Highway Corridor and Intrastate Corridor Existing and projected congestion
and frequent incidents on 185 that temporarily slow or stop traffic (2 589 incidents in 2007 from
Exit 10 (US 29 74) to Exit 29 (I 485)) inhibit travel along this important link in the regional
transportation system Traveling from Mecklenburg County heading west to points in Cleveland
County and points farther south 185 is the only full control of access interstate facility through
Gaston County Also traveling from Mecklenburg County via 185 to points north of Gaston
County such as Hickory or Boone US 321 (north of I 85) is the only full control of access facility
to those destinations from Gaston County and these roadways are essential for regional truck and
■ vehicular traffic

25 foot zone on either side of the construction limits may be impacted Total permanent impacts for the
entire project will not exceed 7 19 acres of wetlands
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
With the exception of W047 W048 W059 and W087 all impacts are to wetlands classified as nverme
Wetland classifications and quality ratings are presented in Table 9 USACE Routine Wetland
Determination Forms and NCDWQ Wetland Rating Worksheets for each site and the USACE Notice of
Jurisdictional Determination are found in Appendix 2
Wetland types that may be impacted by U 3221 include the following Cowardm classifications
PEMI These are palustnne 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 floodplams of streams Some common species in these wetlands include soft rush (Juncus
effusus) bulrush (Scirpus validus) beggars ticks (Bidens anstosa) bushy seedbox (Ludwigia
alternifolta) netted chain fern (Woodwardia areolata) cinnamon fern (Osinunda cinnainomea) giant
cane (Arundinaria gigantea) cattail (Typha latifolia) blackberry (Rubus sp ) tag alder (Alnus serrulata)

and black willow (Salix ntgra) Hydrology is dependent upon landscape position and is typically
groundwater or flood driven due to the location of these wetlands along streams These areas can be
saturated (PEM 1 B) seasonally flooded (PEM 1 C) semi permanently flooded (PEM 1 F) intermittently
exposed (PEM 1 G) and intermittently flooded (PEM 1 J)
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 (Ater rubrum) sweetgum
(Ltgtudambar styraciflua) willow oak (Quercus phellos) tulip poplar (Linodendron tulipifera)
spicebush (Lindera benzoin) downy arrowwood (Viburnum dentatuin) Chinese privet (Ltgustriun
stnense) Japanese grass (Microstegium vnnineum) and netted chain fern Hydrology is dependent 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 (PFO 1 C) a combination of seasonally flooded or saturated (PFO 1 E) semi permanently flooded
(PFO1F) intermittently exposed (PFOIG) and intermittently flooded (PFO1J)
PSS1 These are palustrie 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 radtcans) 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 (PSS 1 A)
saturated (PSS 1 B) seasonally flooded (PSS 1 C) and semi permanently flooded (PSS I F)
PSS3C These are palustnne 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 dnven by groundwater or flooding Common species
include giant cane (Arundmarta gtgantea) Chinese privet and Japanese honeysuckle (Lontcera
japonica)
PUBHh These are palustnne 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
Stream Impacts
The portion of U 3221 that extends from NC 279 to 1485 will impact 7 213 linear feet of streams (6 883
If permanent 3301f temporary) as shown in Figures 4 15 through 4 22 and Appendix 1 Final Design
Permit Drawings The preliminary construction drawings submitted for the remainder of the project
alignment identify the stream impacts within the construction limits of the final alignment (Figures 4 1
through 4 14 and Appendix 1 — Preliminary Construction Drawings) In addition streams that may be
impacted within a 25 foot zone on either side of the construction limits are shown Approximately
23 583 linear feet of streams may be impacted within the construction limits An additional 5 217 linear
feet of streams within the 25 foot zone on either side of the construction limits may be impacted Total
permanent impacts for the entire project will not exceed 35 683 linear feet of streams
All impacts are to warm water streams and occur at 82 separate locations Fifty eight (58) of the streams
impacted are classified as perennial and twenty four (24) are classified as intermittent (Table 10) The
physical characteristics of each stream segment impacted by the project are descnbed in Table 11 The

Worksheets and NCDWQ Stream Identification Forms Version 3 1 are provided in Appendix 2
Open Water / Ponds
The portion of U 3221 that extends from NC 279 to 1485 will impact 0 26 acre of open waters (ponds) as
shown in Figures 4 15 through 4 22 and Appendix 1 Final Design Permit Drawings The preliminary
construction drawings submitted for the remainder of the project alignment identify the open water
impacts within the construction limits of the final alignment (Figures 4 1 through 4 14 and Appendix 1 —
Preliminary Construction Drawings) In addition open waters that may be impacted within a 25 foot
zone on either side of the construction limits are shown Approximately 2 86 acres of open waters may be
' impacted within the construction limits An additional 0 9 acre of open water within the 25 foot zone on
either side of the construction limits may be impacted Total permanent impacts for the entire project will
not exceed 4 02 acres of open water
Of the ten ponds that may be impacted nine are connected to surface waters and one is isolated through
impoundment by roadway fill (Table 12)

Avoidance and Minimization
Description of measures taken to avoid or minimize impacts during selection of preferred
alternative
The development and evaluation of alternatives to determine the Detailed Study Alternatives (DSA)
included in the DEIS is documented in detail in the Addendum to the Final Alternatives Development and
Evaluation Report for the Gaston East West Connector (PBS &J October 2008) As described in Section
2 of the DEIS (http //www ncdot gov/pi olects/ ag rdenparkway ) and Section 2 of the FEIS
(http //www ncdot gov/pipiects/gaideriparkway/) an extensive alternatives analysis was employed to
select the Least Environmentally Damaging Practicable Alternative (LEDPA) for the Gaston East West
Connector
First Screening — Protect Concepts
In the First Screening (Project Concepts) six alternative concepts were evaluated to determine if they
were reasonable and practicable based upon their ability to meet the project s purpose and need
associated potential impacts and their financial feasibility After the project became a candidate toll
facility and 2030 traffic forecasts were completed project concepts were reevaluated considenng tolling
options In the First Screening each alternative was developed to decide whether to retain or eliminate
the alternative concept from detailed study The Improve Existing Roadways Alternatives and the New
Location Alternatives scenarios were developed in more detail than the other concepts For these two
concepts traffic forecasts and traffic operations analyses were prepared Impacts to the human and natural
environments also were considered as part of the First Screening of the Improve Existing Roadways
Alternatives
The project concepts evaluated in the First Screening include
No Build Alternative
Transportation System Management (TSM) Alternative
Transportation Demand Management (TDM) Alternative
Mass Transit Alternative and Multimodal Alternative
Improve Existing Roadways Alternatives
• New Location Alternatives
The First Screening was iterative Initially the First Screening focused on the ability to meet Purpose and
Need Several alternatives were eliminated largely or entirely based on their inability to meet the Purpose
and Need (TSM TDM Mass Transit Multimodal) In response to requests from environmental resource
and regulatory agencies more detailed information about impacts and traffic forecasts was developed for
the Improve Existing Roadways Alternatives and the New Location Alternatives In some instances
financial feasibility also was addressed This iterative process resulted in some alternatives being
developed to a higher level of detail than others in order to determine whether they should be retained for
the Second Screening or eliminated
Qualitative and quantitative performance measures were used in the First Screening to evaluate the
mobility and direct access components To meet the purpose and need an alternative must provide more
than a minor improvement An improvement would be considered minor if it is localized temporary

U 3321 Gaston East West Connector (Garden Parkway)
and /or largely unnoticeable to the typical user of the transportation system Alternatives that provide only
a minor improvement do not meet the purpose and need and therefore are not reasonable alternatives
To evaluate their ability to meet the purpose and need alternative concepts were evaluated to determine
whether they would
Reduce travel distances and /or travel times between representative origin /destination points
within southern Gaston County and between southern Gaston County and Mecklenburg
County
Provide a transportation facility that would operate at acceptable levels of service (generally
Level of Service [LOS] D or better on the mainline) in the design year (2030) for travel
between Gaston County and Mecklenburg County
Reduce congested vehicle miles traveled and/or congested vehicle hours traveled in Gaston
County compared to the No Build Alternative in 2030
No Build Alternative
The No Build Alternative is the baseline alternative for the design year which is 2030 for this
project In general the No Build Alternative assumes that the transportation systems for Gaston
County and western Mecklenburg County would evolve as currently planned in the Gaston Urban
Area Metropolitan Planning Organization (GUAMPO) 2030 Long Range Transportation
Plan (LRTP) and in the Mecklenburg Union MPO (MUMPO) 2030 LRTP but without the
proposed project In addition the No Build Alternative also does not assume completion of the
US 321 Bypass funding for that project is too uncertain to assume that it will be completed by
2030
Traffic operations analyses for the No Build Alternative conclude that 185 in the Project Study
Area is projected to operate at LOS E and F in 2030 US 29 74 is projected to operate at LOS F
east of McAdenville 1485 is projected to operate at LOS E The No Build Alternative would
not meet the project s purpose and need It would not improve mobility access or connectivity in
southern Gaston County nor between southern Gaston County and western Mecklenburg County
Also it would not improve travel times within southern Gaston County nor between southern
Gaston County and western Mecklenburg County nor would it provide a facility that operates at
an acceptable level of service in the design year (2030) For this reason the No Build Alternative
was eliminated from further consideration
However in accordance with the National Environmental Policy Act (NEPA) (40 CFR
502 14(d)) and FHWA guidance (Technical Advisory T 6640 8A p 16) the No Build Alternative
is given full consideration in this DEIS to provide a baseline for comparison with the DSAs
Transportation System Management (TSM) Alternative
The TSM Alternative includes modest physical and operational enhancements to improve performance
safety and management of traffic operations without mayor construction These improvements may
include installing or optimizing traffic signals adding medians or turn lanes ramp metering and other
simple measures to improve traffic flow within the Project Study Area When used these alternatives
generally yield fewer impacts on the environment shorter implementation schedules for various
components and lower costs but also reduced benefits

Fifty eight intersection and ramp improvements at nineteen locations were included in the TSM
Alternative The locations and improvements are listed in the Addendum to the Final Alternatives
Development and Evaluation Report for the Gaston East West Connector (PBS &J October 2008) The
nineteen locations include the ramps and/or ramp terminus intersections at eleven exits along 185 six
intersections along US 29 74 and two intersections along US 321 The nineteen improvement locations
are areas wherein potential deficiencies in intersection or ramp operations became apparent when
evaluating year 2025 traffic operations for the Improve Existing Roadways Alternatives (Phase H Traffic
Analysts Technical Memorandum Gaston County East West Corridor Study PBS &J February 2004)
TSM improvements alone would not meet the purpose and need of the proposed project Therefore the
TSM Alternative was eliminated from further study Key factors considered in reaching this decision
included
TSM improvements on 185 ramps and ramp termini US 29 74 and US 321 would not
noticeably improve mobility access or connectivity within southern Gaston County nor
between southern Gaston County and western Mecklenburg County Travel distances would
remain the same and travel times would not be noticeably reduced
Although signal coordination and intersection improvements at 185 ramp termini and selected
locations along US 29 74 and US 321 could provide minimal improvements to traffic flow
along US 29 74 US 321 and cross streets over 185 the volumes of projected traffic would
cause congestion and poor levels of service (LOS E or F) on 185 and congestion would
continue on US 29 74 and US 321 These minimal improvements would not be expected to
noticeably improve congested vehicle hours or miles traveled in Gaston County compared to
the No Build Alternative
Transportation Demand Management (TDM) Alternative
The TDM Alternative includes measures and activities that change traveler behavior and typically do not
involve major capital improvements The TDM Alternative includes demand management strategies
currently being implemented in Gaston and/or Mecklenburg County These include a freeway
management system staggered work hours and flex time (employer focused) and one additional
measure not currently being implemented involving the conversion of existing lanes on 185 to high
occupancy vehicle (HOV) lanes or high occupancy toll (HOT) lanes North Carolina legislation (NCGS
136 89 187) prohibits converting any segment of the non tolled state highway system to a toll facility
so a TDM Alternative involving conversion of existing free lanes on 185 to HOT lanes is not possible
without a change in state law
The TDM Alternative was eliminated from further consideration because it would not meet the projects
purpose and need Key factors considered in reaching this decision included
TDM measures would not improve mobility access or connectivity within southern Gaston
County nor between southern Gaston County and western Mecklenburg County Travel
distances would remain the same and travel times would not be noticeably reduced
Freeway management system measures such as dynamic message boards ramp meters incident
' management systems etc would help optimize the efficiency of traffic flow on existing 185
but 185 would remain congested due to the projected high volumes of traffic HOV lanes
would improve traffic flow along existing 185 for travelers using those lanes but general

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
purpose lanes on 185 would remain congested The TDM alternative also would not reduce
congestion on US 29 74 and US 321
This minimal level of improvements would not be expected to noticeably improve congested
vehicle hours or miles traveled in Gaston County compared to the No Build Alternative
Mass Transit Alternative
The Mass Transit Alternative would include bus or rail passenger service For purposes of screening this
alternative was considered in two ways (1) a version that only includes improvements to existing
facilities and (2) a version that includes construction of transit on new alignment The existing facilities
version would include expansion of existing bus routes on existing roadways or potential use of the
existing rail corridor that generally parallels 185 and is currently used for freight traffic and Amtrak
passenger rail service The version that includes transit on new location would include a dedicated new
alignment for light rail or bus rapid transit connecting southern Gaston County to west Mecklenburg
County This new location transit facility would generally follow the corridors of the proposed new
location roadway alternatives Ideally this transit service would connect to the planned transit service in
the Charlotte Area Transit System (CATS) West Corridor
CATS is planning and implementing a mayor expansion of its mass transit service throughout
Mecklenburg County One of the five mayor corridors under study is the West Corridor which extends
from uptown Charlotte to Charlotte Douglas International Airport along the US 29 74 corridor (2030
Transit Corridor System Plan Metropolitan Transit Commission November 2006) CATS plans to
implement enhanced bus service to Charlotte Douglas International Airport A streetcar system is
planned from uptown Charlotte to the airport beginning in 2024 (Charlotte Mecklenburg Web site
www charmeck org /Departments/ CATS / Rapid +Transit+Plannin�z/West +Corridor /) The City of Gastonia
and the GUAMPO studied improving transit in the Gastonia Charlotte corridor (Gastonia Rapid Transit
Alternatives Study Corridor and Modal Options December 2005) Relevant recommendations from the
report included increasing service for Route 85X the express route from Gastonia to uptown Charlotte
and coordinating with CATS regarding the West Corridor and any improvements into Gaston County
The Mass Transit Alternative using expanded bus service on existing roadways or expanded rail service
on the existing rail line near 185 was eliminated from further study because it would not meet the
project s purpose and need The Mass Transit Alternative including bus rapid transit or light rail on new
alignment also was eliminated from further study because although it could provide increased
connectivity and mobility it would not meet the project s purpose and need and would not be financially
feasible Key factors considered in reaching this decision included
Expanded bus service that uses existing roadways or rail service that uses the existing rail line
near 185 would not establish direct connectivity within southern Gaston County or between
southern Gaston County and west Mecklenburg County The bus service would continue to
use existing roadways projected to operate at poor levels of service (LOS E or F) Neither the
bus service nor rail service would attract enough trips to noticeably reduce vehicle miles
traveled and/or congested vehicle miles traveled in Gaston County compared to the No Build
Alternative nor would travel times or distances noticeably improve
Rapid transit service (bus or light rail) on dedicated new alignment would provide increased
mobility between Gaston County and Mecklenburg County by providing an alternative travel
mode choice It could also provide connectivity within southern Gaston County and between
Page 4 of 17

I
Attachment 8 BLOCK 23 — Avoidance Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
southern Gaston County and west Mecklenburg County and provide shorter travel times or
distances for the transit users However the Mass Transit Alternative on new alignment
would carry a much lower volume of trips than a new highway facility and would be ill
suited to the dispersed low density land uses in southern Gaston County (resulting in even
less trips) The resulting lower volume of trips accommodated would not noticeably reduce
vehicle miles traveled and/or congested vehicle hours traveled in Gaston County compared to
the No Build Alternative
Construction costs for a Mass Transit Alternative that is on dedicated new alignment through
southern Gaston County and connecting across the Catawba River to Mecklenburg County
and CATS West Corridor would be extensive Mass transit on new alignment through the
Gaston East West Connector project study area would be at least 22 miles long (likely longer
to connect to the West Corndor) If a 22 mile long Gaston Mass Transit Alternative light rail
project could be built for the same per mile cost as the CATS South Corridor Light Rail
Project it would have a cost of at least $1 06 billion In fact the per mile cost of a Gaston
East West Connector new location light rail facility would likely be substantially higher than
the South Corridor project due to inflation the need to purchase right of way (very little new
right of way was required for the South Comdor Light Rail Project since it utilized an
existing rail comdor) and the mayor structures (bridges) that would need to be constructed
over the South Fork Catawba River and the Catawba River There is no program currently in
place within North Carolina or in Gaston County to fund such improvements
Multimodal Alternative
The Multimodal Alternatives would include the Mass Transit Alternative together with improvements to
existing roadways The roadway improvements could include those described for the TSM Alternative or
those described for the Improve Existing Roadway Alternatives Thus the Multimodal Alternative is
essentially a combination of the TSM Alternative and the Mass Transit Alternative or a combination of
the Improve Existing Roadways Alternatives and the Mass Transit Alternative For purposes of
screening this alternative was considered in two ways (1) a version that only includes improvements to
existing facilities and (2) a version that includes improvements to existing facilities as well as
construction of transit on new location
The TSM Alternatives the Improve Existing Roadways Alternatives and the Mass Transit Alternatives
would not meet the projects purpose and need Combinations of these alternatives as Multimodal
Alternatives also would not meet the projects purpose and need Key factors considered in reaching this
decision included
A Multimodal Alternative could be defined to include expanded bus or rail service that uses
existing roadways together with either TSM improvements or improvements to existing
roadways These potential combinations of roadway and transit improvements would not
meet the Purpose and Need They would not establish direct connectivity within southern
Gaston County nor between southern Gaston County and west Mecklenburg County In
addition these potential combinations would not attract enough trips to noticeably reduce
vehicle and/or congested vehicle miles traveled in Gaston County compared to the No Build
Alternative They would not provide a facility with an acceptable level of service because
they would not attract enough trips to change the poor levels of service projected to occur on
185 and other area roadways under the TSM Alternative or Improvement Existing Roadways
Page 5 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
Alternatives Travel times and distances also would not noticeably improve Because this
version of the Multimodal Alternative would not meet the Purpose and Need it is not a
reasonable alternative
A Multimodal Alternative also could be defined to include transit on new location in
combination with improvements to existing roadways These potential combinations also
would not meet the purpose and need and would likely be cost prohibitive Rapid transit
service (bus or light rail) on dedicated new alignment would provide increased mobility
between Gaston County and Mecklenburg County by providing an alternative travel mode
choice It could also provide some improved connectivity within southern Gaston County
and between southern Gaston County and west Mecklenburg County and provide shorter
travel times or distances for the transit users However mass transit on new alignment would
carry a much lower volume of trips than a new highway facility and would be ill suited to the
dispersed low density land uses in southern Gaston County Neither the bus service nor rail
service on new alignment would attract enough trips to noticeably reduce vehicle miles
traveled and /or congested vehicle miles traveled in Gaston County compared to the No Build
Alternative nor would it attract enough trips to change the poor levels of service projected to
occur on 185 and other area roadways under the TSM Alternative or Improvement Existing
Roadways Alternatives Travel times and distances also would not noticeably improve for
non transit users Therefore while a Multimodal Alternative with transit on new location
would improve mobility for transit users it would not meet the Purpose and Need and is not a
reasonable alternative
Construction costs for a Mass Transit Alternative that is on dedicated new alignment through
southern Gaston County and connecting across the Catawba River to Mecklenburg County
would be extensive Adding TSM improvements or improvements to existing roadways
under the Multimodal Alternative would make the Multimodal Alternative with new location
mass transit even more expensive than the Mass Transit Alternative There is no program
currently in place within North Carolina or in Gaston County to fund the transit
improvements and at this time the Mass Transit Alternative and consequently the
Multimodal Alternative that includes mass transit on new alignment are not financially
feasible The lack of financial feasibility is an additional reason for finding that this
alternative is not a reasonable alternative
Improve Existing Roadways Alternatives
Two versions of the Improve Existing Roadways Alternative were evaluated using forecasts from the
2030 travel demand model Scenario 4 and Scenario 8 These Improved Roadways Alternatives were
modeled as Non Toll Scenarios and Toll Scenarios were also considered
Other scenario numbers (Scenarios 1 2 3 5 5a 6 and 7) are documented in the Gaston County East
West Connector Study Transportation Demand Modeling Technical Memorandum (Martin/ Alexiou/
Bryson February 2005) Scenario 1 was the No Build Scenario Scenarios 2 and 3 were interim
networks used strictly to evaluate sensitivities in the travel demand model for improvements to existing
roadways and were not developed nor intended to be developed as Improve Existing Roadways
Alternatives Scenarios 5 5a 6 and 7 were various configurations of the New Location Alternative used
to determine sensitivities to number of lanes (four lanes for Scenario 5 or six lanes for Scenario 5a) and
location of alignment (Scenarios 6 and 7)
Page 6 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
Improve Existing Roadways Alternatives Scenario 4 and Scenario 8 include widening 185 by one to two
general purpose lanes in each direction The new capacity on 185 could be implemented as toll lanes
Three toll options were considered for the new capacity on 185 These options from most to least
intensive improvements and right of way requirements include constructing a fully barrier separated toll
facility constructing toll or HOT lanes with a lower level of physical separation from the non toll lanes
(such as delineating buffer zones by pavement markings) or reconfiguring existing pavement to add the
toll or HOT lanes
Year 2030 regional network statistics project an increase in congested travel with Scenario 4 as compared
to the No Build Alternative Adding capacity to 185 causes some reduction in congestion on 185 itself
but 185 still remains congested and congestion actually increases on other routes that feed into 185
Scenario 4 would not improve travel times mobility access or connectivity within southern Gaston
County or between southern Gaston County and western Mecklenburg County Like Scenario 8 it would
result in the greatest construction delays of all alternative concepts and would disrupt local and through
travelers for an extended period of time Bridge deck construction for 185 widening would require
intermittent closures of 185 with poor alternatives available for off site detours of 185 traffic If
capacity on 185 is added by restnping existing pavement the resulting substandard lane and shoulder
widths would require a design exception not likely to be approved by FHWA
With Scenario 8 the traffic forecasts would likely show less congestion than under Scenario 4 because
Scenario 8 includes improvements to the north south feeder routes that serve 185 Scenario 8 may
represent a net improvement over the No Build Alternative in terms of congestion levels However the
improvements with Scenario 8 would likely be less than improvements achieved with the New Location
Alternative The feeder road widening in Scenario 8 would allow more traffic to be delivered to the same
bottlenecks faster This alternative would not produce enough improvements in congestion levels to
compete with the New Location Alternatives
Scenario 8 provides minimal improvements to connectivity between southern Gaston County and western
Mecklenburg County and would not improve east west mobility within southern Gaston County
Scenario 8 provides no travel time savings compared to the No Build Alternative Along with Scenario
4 this scenario would result in the greatest construction delays of all alternative concepts disrupting local
and through travelers for an extended period of time As in Scenario 4 bridge deck construction for 185
widening would require intermittent closures of 185 with poor alternatives available for off site detours
for 185 traffic If capacity on 185 is added by restnping existing pavement resulting substandard lane
and shoulder widths would require a design exception not likely to be approved by FHWA Scenario 8
would also have high levels of impacts to the human and natural environments
Only minimal improvements to traffic flow on 185 would be achieved with the Improve Existing
Roadways Alternatives and 185 would continue to operate at LOS E and F Most improvements in
traffic flow achieved by increasing additional capacity would be offset by the increase in traffic volumes
attracted to the facility If the new lanes on 185 were tolled the tolled lanes would have less accessibility
than if the new capacity was used for general purpose lanes The existing (non tolled) lanes on 185
would remain congested The Improve Existing Roadways Alternatives would not improve east west
connectivity or mobility within southern Gaston County or between southern Gaston County and western
Mecklenburg County and travel times for most intra and inter county trips would lengthen compared to
Page 7 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
the No Build Alternative For example improvements to existing roadways result in longer travel times
because the north south roads in the Project Study Area become more congested with travelers seeking
access to the widened 185
New Location Alternatives
The New Location Alternative would extend from 185 west of Gastonia through southern Gaston
County to connect to 1485 and NC 160 in western Mecklenburg County There would be new bridge
crossings of the South Fork Catawba River and the Catawba River The New Location Alternative (Non
Toll and Toll Scenarios) would meet the project s purpose and need Also this alternative concept would
be consistent with local transportation plans However only the Toll Scenario is retained for detailed
study because the Non Toll Scenario is not financially feasible
The New Location Alternative improves connectivity and travel times between southern Gaston County
and western Mecklenburg County by providing a new crossing of the Catawba River It improves
connectivity mobility and travel times within southern Gaston County and improves traffic flow and
some levels of service on 185 US 29 74 and US 321 The New Location Alternative could serve as a
controlled access alternate route during incidents on 185 Drawbacks to the New Location Alternative
are that it would have substantial construction and right of way costs and impacts to the natural
environment would likely be greatest compared to the other alternative concepts
Second Screening — Protect Corridors
In the Second Screening (Project Corridors) the alternative concept that survived the First Screening
process (the New Location Alternative) was further refined and evaluated to determine the specific
Detailed Study Alternatives (DSAs) Approximately 116 miles of Preliminary Corridor Segments were
developed for the New Location Alternatives The Preliminary Corridors were then evaluated and
compared in order to narrow that group down to the Functional Design Corndors There were 90
endpoint to endpoint alternatives (from 185 to I 485) that were created from the Functional Design
Corridors Functional roadway designs were prepared for this set of alternative corridor segments
Impacts to the human and natural environments were estimated based upon the functional roadway
designs DSAs were identified based upon design considerations estimated impacts and agency /public
input
Preliminary roadway designs were then prepared for the DSAs The preliminary engineering designs
include more detail than the functional roadway designs The impacts documented in the DEIS are based
upon the preliminary engineering designs for the DSAs The DSAs were reevaluated in 2008 based on
new information provided by Duke Energy Corporation regarding operations at the Allen Steam Station
The preliminary engineering designs also were reevaluated to venfy they would provide adequate
capacity for implementing the project as a toll facility Selection criteria for the preliminary roadway
designs included design factors socioeconomic and historic resource criteria hazardous waste sites and
natural resource criteria
Recommended Alternative
DSA 9 was identified by the FHWA NCTA (a division of NCDOT since July 27 2009) and NCDOT as
the Recommended Alternative in the DEIS The FHWA and NCTA have identified DSA 9 as the
Preferred Alternative in the FEIS The following considerations were used in selecting DSA 9
Page 8 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
Cost and Design Considerations
DSA 9 is one of the shortest alternatives at 21 9 miles
DSA 9 had the second lowest median total cost
Human Environment Considerations
DSA 9 is one of the four DSAs with the fewest numbers of residential relocations
Although DSA 9 is higher in the range of business relocations it would avoid impacts to Carolina
Specialty Transport (provides transportations services to special needs groups) that would occur
under six of the DSAs
DSA 9 is in the middle of the range of total neighborhood impacts DSA 9 is one of four that
would have no direct impacts to schools
DSA 9 is one of eight DSAs that would not require relocation of known cemeteries
At Linwood Road DSA 9 is one of three alternatives that would avoid impacting either the Karyae
Park YMCA Outdoor Family Center or the Pisgah Associate Reformed Presbyterian Church (part
of the church property is also an historic site eligible for listing on the National Register of
Historic Places)
DSA 9 is one of the three alternatives farthest from Crowders Mountain State Park
DSA 9 and seven other DSAs would avoid right of way requirements from Daniel Stowe Botanical
Garden
DSA 9 and seven others would avoid the relocation of Ramoth AME Zion Church and cemetery
which is part of the Garnson Road/Dixie River Road community
DSA 9 right of way would not encroach on Berewick Regional Park in Mecklenburg County
Physical Environment Considerations
DSA 9 is in the middle range of estimated numbers of receptors impacted by traffic noise
DSA 9 is one of six alternatives that would impact the least acreage of land in Voluntary
Agricultural Districts DSA 9 also is one that is expected to have the least indirect and
cumulative effects to farmlands
DSA 9 is one of the alternatives with the fewest power transmission line crossings
Cultural Resources Considerations
• DSA 9 is one of six alternatives that would not require right of way from the Wolfe Family Dairy
Farm historic site Selection of DSA 9 makes it more likely that if the US 321 Bypass is
constructed at some future time the project would also avoid the Wolfe Family Dairy Farm historic
' site
DSA 9 is one of four alternatives with low to moderate potential to contain archaeological sites
requiring preservation in place or complex/costly mitigation
tNatural Resources Considerations
DSA 9 is one of eight alternatives that would cross the South Fork Catawba River and the Catawba
River where the rivers have been more affected by siltation and they are less navigable and
water based recreation would be affected less than with DSAs that cross farther south
DSA 9 would impact the least amount of Upland Forested Natural Communities
DSA 9 is one of four alternatives having the lowest potential to indirectly affect upland wildlife
species due to habitat fragmentation
' DSA 9 is lower in the range of impacts to ponds
' Page 9 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
DSA 9 is lower in the range of impacts to wetlands
DSA 9 is lower in the range of impacts to perennial streams
DSA 9 would have the fewest number of stream crossings
DSA 9 is one of eight alternatives that have a biological conclusion of No Effect relating to the
federally endangered Schweinitz s sunflower
Based on impact evaluations DSA 9 has been identified as the LEDPA It is one of the three DSAs with
the fewest impacts to jurisdictional resources and the one which provides the best overall balance of
impacts when considering both Jurisdictional and non jurisdictional resources DSA 9 was in the lower
range of impacts to ponds wetlands and perennial streams and had the fewest number of stream
crossings
No Permit Alternative
The No Permit Alternative considers the development of the Gaston East West Connector without
placement of fill into waters of the US and therefore without a need for permit issued by the USACE
pursuant to Section 404 of the CWA The NCTA has concluded that development of the Gaston East
West Connector under the No Permit Alternative would not satisfy the purpose and need of the proposed
project Avoidance of all impacts to junsdictional resources by bridging is neither feasible nor practicable
due to cost and logistics The NCTA has concluded that the development of the Gaston East West
Connector under the No Permit Alternative would not be feasible or prudent and that this alternative
would be equivalent to the No Build Alternative
Description of measures taken to avoid or minimize impacts during design
For the preliminary designs shown in the DEIS the horizontal alignment of the preliminary designs was
adjusted where possible to minimize or avoid impacts to streams wetlands and ponds The presence of
wetlands and streams and the minimization or avoidance of impacts to these resources were factors in
considering interchange configurations Bridge lengths would be extended to maintain roadway and
railway access adjacent to the Catawba River and South Fork Catawba River which would avoid or
minimize encroachment into Catawba River buffer areas
To further address avoidance and minimization documented in the DEIS the NCTA met with the
environmental resource and regulatory agencies ( USACE NCDWQ USFWS USEPA NCWRC) at
TEAC Meetings on February 5 March 4 and April 8 2008 to discuss bridging and alignment decisions
for the DSAs preliminary designs In the NEPA/404 Merger Process (DEIS Section 9 2 3) this is
Concurrence Point 2a — Bridging/Alignment Decisions As a result of those meetings there were no
changes to the alignments of any of the DSAs However the NCTA agreed to include several bridges in
the preliminary designs beyond those required to convey floodwaters to avoid or minimize stream and
wetland impacts These bridge locations for the Preferred Alternative include a bridge over Blackwood
Creek (Stream S 135) and the lengthening of the mainline bridge over Catawba Creek to span the main
body of Wetland W248
Impacts to wetlands and streams were further reduced through the design refinements made to the
Preferred Alternative even with inclusion of service roads as described in Section 2 3 3 of the FEIS
Specifically the refined preliminary design for the Preferred Alternative resulted in an approximate 25
Page 10 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
percent reduction in stream impacts (2 36 miles) an approximate 6 percent reduction in wetland impacts
(0 4 acre) a slight increase in impacts to ponds (0 4 acre) and a slight decrease in Catawba River buffer
impacts compared to the preliminary design for DSA 9 documented in the DEIS
As design progresses for sections U 3221 A U 3221 B and U 3221 CA an overall reduction in impacts to
junsdictional areas is anticipated For example total stream impacts for the Preferred Alternative have
decreased by 403 linear feet as a result of final design changes on section U 3321CB (Table 13)
However as occurred with section U 3321 CB increases in impacts may occur at certain sites due to
design changes requested by the review agencies to ensure stable channels or the determination that a
total taking of jurisdictional areas will occur based on the final design
Development of the Project's Typical Section
The design cnteria and typical roadway cross section for the project are influenced by the type of facility
required to fulfill the project s anticipated design year traffic forecasts as well as meet the purpose and
need of the project Throughout the alternatives development and screening process alternatives were
designed to meet the needs of projected traffic forecasts The typical section to meet the 2035 Toll Traffic
Forecast would be four through lanes A 70 foot grassed median was assumed because the NCDOT
Roadway Design Manual indicates that width is the standard median width for freeway facilities
After selection of the LEDPA and in order to further avoid and minimize impacts of the Preferred
Alternative the NCTA proposed a reduction in the median width to 50 feet and a reduction in nght of
way to a minimum of 280 feet The typical section (see Final EIS Figure 2 2) for the Preferred
Alternative includes four lanes with a 50 foot median (including two 12 foot shoulders and 26 feet of
grass area) Agencies concurred as part of the NEPA/404 Merger Process Concurrence Point 4A
(February 16 2010) that the NCTA had demonstrated avoidance and minimization of project impacts
More importantly the need for a grassed median is based on a number of factors
Compliance with NCDOT Standards
NCDOT s Roadway Design Manual states that the pnmary objective of highway design is to design a
safe functional aesthetically appearing facility which is adequate for the design traffic volumes for the
minimum life cycle costs These standards further dictate that a 46 foot median is the minimum median
width to be used for freeways without a concrete median bamer and that this minimum width is used
when significant right of way terrain or environmental restraints prohibit or restrict the use of the
standard 70 freeway median So although a 70 foot median is the preferred median width for freeway
facilities the NCTA has proposed the 50 foot median width for the proposed facility in order to avoid and
minimize impacts while maintaining a safe functional aesthetically appearing facility
Safety
One of the identified needs for this project was the need to improve traffic flow on the sections of 185
US 29 74 and US 321 in the project Study Area and improve high speed safe reliable regional travel
service along the 185 corridor (see Draft EIS Section 1 3) Studies have shown that there is a direct
correlation between median width and the number of cross median crashes According to a recent
National Cooperative Highway Research Program (NCHRP) Report the effect of median width on
crashes is approximately an 8 percent reduction with every 10 foot increase in median width This report
Page 11 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
also notes that median related crashes peak when the median width is about 30 feet and then decrease as
the median becomes wider than 30 feet
Drainage and Stonnwater Treatment
Maintaining a 50 foot median allows for drainage and stormwater treatment in the median via grass
swales Grass swales have been proven to filter pollutants as stormwater runoff moves through the
vegetation as well as reducing flow velocities minimizing concentrated discharges and reducing peak
runoff Reducing the median below 46 feet requires use of a concrete barrier to separate directions of
travel In the case of a 22 to 26 feet median the typical section would include four lanes with 10 foot
inside paved shoulders and a 2 foot concrete barrier (i e jersey type barrier) Therefore the median is
paved in its entirety and a closed drainage system is required to accommodate stormwater using a system
of underground pipes to transport stormwater to an outlet This results in need to treat more water at a
higher flow velocity with more concentrated pollutants Closed drainage systems are most commonly
used in urban settings where right of way is not available for construction of the preferred vegetative
ditches and swales
Context Sensitive Design
Public input on this project has indicated a strong desire for a facility that fits the relatively rural character
of the project area even referring to the project locally as the Garden Parkway after the Stowe
Botanical Gardens in the area Therefore the Turnpike Authority has designed the facility with context
sensitivity and aesthetic design in mind A series of meetings with stakeholders as well as design
workshops with a variety of technical experts have resulted in a Corridor Design Guide that represents
community issues local land use patterns community landmarks and natural features The guide
addresses overall corridor treatments and individual design elements such as lighting bridge aesthetics
soundwalls retaining walls branding and color The 50 foot median is compliant with the Corridor
Design Guide and provides a more context sensitive and aesthetically pleasing design consistent with
local desires and plans
Cost
Construction of this facility with a 22 to 26 feet median width would be more costly Additional costs
would include the concrete median barrier as well as installation and maintenance of a closed drainage
system The Turnpike Authority estimates the additional cost to be approximately $6 million per mile or
more than $130 million for the project s construction cost This represents a nearly 18 percent increase in
the construction cost
Conclusion
The NEPA/404 Merger Process has kept all agencies informed and involved in the environmental analysis
for the project The agencies have concurred that the Preferred Alternative is the LEDPA Updated traffic
forecasts show that a four lane facility with a grass median is needed to satisfy the project s purpose and
need through the design year 2035 The Turnpike Authority has made avoidance and minimization
measures to reduce the grass median from the preferred 70 feet to a still acceptable 50 feet

Description of measures taken to avoid or minimize impacts during construction
NCTA will follow the Design Standards in Sensitive Watersheds (15A NCAC 04B 0124) for
implementing sedimentation and erosion control Best Management Practices (BMPs) along the entire
project corridor
Measures will be taken to reduce the V 10 discharge from ditches that discharge into jurisdictional
streams (Table 14)
Compensatory Mitigation
The 2008 Federal Mitigation Rule (33 CFR Parts §325 and §332) provides a recommended hierarchy for
compensatory mitigation The recommended hierarchy for mitigation methods includes 1) mitigation
banks 2) in lieu fee program credits and/or 3) permrttee responsible mitigation Mitigation banks are
sites (or a suite of sites) where aquatic resources are restored for the purpose of providing mitigation to
offset project related impacts In Lieu Fee programs involve restoration of aquatic resources through
funds paid to a governmental or non profit entity to satisfy mitigation requirements Permittee responsible
mitigation is an activity undertaken by the permitee to restore enhance or preserve aquatic resources to
provide mitigation to offset project impacts Under permrttee responsible mitigation the responsibility for
mitigation remains with the permrtee
In response to agency requests for the compensatory mitigation to be implemented in proximity to project
impacts the NCTA will provide compensatory mitigation for the Garden Parkway through a combination
of use of the NC Department of Environment and Natural Resources Ecosystem Enhancement Program
In Lieu Fee program and on site permrtee mitigation As described in the Gaston East West Connector
Conceptual Mitigation Plan Revised October 2011 (Appendix XX) on site mitigation opportunities were
identified through a GIS analysis performed within parcels located adjacent to or nearby the Preferred
Alternative right of way
Ecosystem Enhancement Program (EEP)
The EEP will provide mitigation for this project in accordance with the 2010 EEP In Lieu Fee Instrument
and the North Carolina Department of Environment and Natural Resources and the North Carolina
Department of Transportation Memorandum of Agreement Governing EEP Operations (November 14
2008) Throughout the development of this project EEP has regularly been apprised of anticipated
mitigation requirements to ensure that sufficient mitigation credits are available As stated in letters dated
July 11 2011 and January 24 2012 EEP has agreed to provide sufficient compensatory stream and
wetland mitigation credits and riparian buffer mitigation credits to offset impacts associated with the
project As stated in the July 11 2011 letter all stream mitigation credits resulting from the Beaverdam
Creek full delivery mitigation project located adjacent to the DSA 9 corridor will be applied to U 3321
Further discussion of the Beaverdam Creek mitigation project is provided below
Beaverdam Creek
The Beaverdam Creek mitigation project is located in Mecklenburg County dust south of the Gaston East
West Connector interchange with 1485 (Figure 3 Appendix 4) The project lies within NCDWQ
subbasm 03 08 34 and hydrologic unit 03050101 of the Catawba River Basin This mitigation project was
developed by the EEP in lieu fee program but may also be considered as on site mitigation for the Gaston
East West Connector based on its location adjacent to the DSA 9 corridor (approximately 1500 feet from
the right of way alignment) Mitigation from the project includes the restoration enhancement and
preservation of 15 806 linear feet of Beaverdam Creek and two unnamed tributaries (UT1 and UT2 and
their associated tributaries) Activities completed for the project include Priority 1 and Priority 2 stream

restoration Level 1 stream enhancement invasive species removal and planting of native riparian
vegetation
The Beaverdam Creek mitigation protect is in the fifth year of monitoring (2011) and is expected to
deliver 13,534 60 stream mitigation units (13,014 restoration credits and 520 60 restoration
equivalent credits)
Permitte Responsible Mitigation
Linwood Springs Restoration Site
The Linwood Springs Golf Course located on Linwood Road in southwest Gastonia encompasses two
parcels located adjacent to the Preferred Alternative The golf course was purchased by NCDOT on June
8 2011 Five additional landlocked parcels adjacent to the eastern boundary of the golf course may be
purchased during right of way acquisition The combined parcels would provide for a permanent
conservation easement of 198 acres for on site mitigation as the Linwood Springs Restoration Site The
rational for selecting the Linwood Spnngs Restoration Site is based on its close proximity to the Gaston
East West Connector Preferred Alternative and the opportunity to provide significant ecological
improvements to streams within an impaired watershed Approximately 5 697 linear feet of Crowders
Creek a 303[d] listed stream for impaired biological integrity resulting from urban runoff and storm
sewers are located within the golf course In addition the golf course and landlocked properties contain
four unnamed tributaries nine vegetated wetlands and nine open water ponds that drain surface water to
Crowders Creek
The primary goals of this restoration project are as follows
1 Re establishing the capacity to store and transport watershed flows and sediment loads by
restoring stable dimension pattern and profile
2 Reducing sediment within on Site and downstream receiving waters through the stabilization of
eroding stream banks and restoration of a forested riparian buffer
3 Restoring and expanding natural wetland hydrology and plant communities
4 Introducing surface water flood hydrodynamics within the floodplam by reestablishing
characteristic bankfull dimensions and flood frequency
5 Improve water quality by removing non point sources of pollution associated with pesticides
herbicides and fertilizer by filtering sheet flow through a restored riparian buffer and installed
Riparian Best Management Practice (RBMP) detention devices
6 Improving aquatic habitat by reducing sedimentation enhancing stream bed variability and
introducing shading woody debris and detritus from riparian planting
7 Enhancing terrestrial wildlife habitat by extending a terrestrial wildlife corridor and refuge to
connect with the upstream and downstream reaches of Crowders Creek
Restoration of the Site accomplishes the watershed approach to compensatory mitigation through an
opportunity to reduce physical and chemical stressors to Crowders Creek its tributaries and the
downstream watershed
The Linwood Springs Restoration Site is expected to provide approximately 10,055 stream
mitigation units and 2 1 wetland mitigation units
On Site Mitigation
On site mitigation opportunities were identified through a GIS analysis performed within parcels located
adjacent to or nearby the Preferred Alternative right of way Adjacent refers to parcels that have a
Page 14 of 17

Attachment 8 BLOCK 23 — Avoidance, Minimization and Compensation
U 3321 Gaston East West Connector (Garden Parkway)
portion of their area within the right or way but the remainder has existing access Nearby parcels refer
to those that are not contiguous with the right of way but were selected because they contain a portion of
a stream or wetland located within an adjacent parcel and could be acquired to create a larger mitigation
site Nearby parcels were limited to those that are located one parcel away from the right of way
Landlocked parcels that may be purchased by NCTA were also included in the GIS analysis and include
those parcels which have a preliminary service road identified to provide access or will no longer have
access following construction of the Gaston East West Connector
The GIS analysis resulted in a total of 43 on site mitigation opportunities Each of the 43 sites is
composed of stream and wetland resources that were grouped together based on proximity to one another
The Sites were consolidated into a Project Atlas and summarized within the Conceptual Mitigation Plan
(Appendix 4) A field evaluation was performed on a total of 65 parcels belonging to landowners who
expressed interest in voluntary mitigation The field reviews consisted of a qualitative assessment of each
parcel including approximate resource extent site characteristics mitigation potential and various site
constraints Specifically reviews were focused on identifying opportunities for stream and wetland
preservation enhancement and /or restoration
Following the field review 33 parcels were found to offer mitigation potential in the form of stream and
wetland preservation The 33 parcels offering stream and wetland preservation were grouped together into
14 sites based on hydrologic connectivity and proximity to one another Grouping parcels allows for
longer contiguous stream lengths and wetland acreages which are ultimately more practicable and
ecologically beneficial as mitigation The 14 preservation sites are presented within an updated Project
Atlas provided in Appendix 4
The on site preservation opportunities may provide up to 40,065 linear feet of stream and 8 3 acres
of wetland potentially providing up to 8,013 stream mitigation units and 17 wetland mitigation
units
Summary
With the exception of the EEP mitigation assets and the purchase of the Linwood Springs Golf Course
the other potential mitigation resources listed in the Conceptual Mitigation Plan have not been acquired at
this time These other potential mitigation resources require additional evaluation including an
assessment of feasibility more detailed determination of the amount of wetland or stream credits present
on the potential site and contact and buy in with property owners The Conceptual Mitigation Plan
serves to document that there are sufficient potential mitigation sites to cover the compensatory mitigation
needs of the Gaston East West Connector
The NCTA and FHWA will work with the environmental resource and regulatory agencies dunng the
permitting phase to further refine the mitigation plan for the project
Habitat Enhancement Program Mitigation Plan
The Habitat Enhancement Program (HEP) Mitigation Plan was created by the NC Turnpike Authority in
response to comments and concerns raised by the US Fish and Wildlife Service (USFWS) and the NC
Wildlife Resources Commission (NCWRC) The Mitigation Plan summarizes the avoidance and
minimization and mitigation measures to be implemented to offset impact to fish and wildlife habitats
within the Lake Wylie Federal Energy Regulatory Commission (FERC) project boundary that may be
caused by the proposed project (see Appendix 7)

The Preferred Alternative for the Gaston East West Connector (Garden Parkway) crosses Lake Wylie a
part of Duke Energy Corporation s Catawba Wateree hydro power project licensed by the FERC The
Preferred Alternative crosses Lake Wylie at the Catawba River South Fork Catawba River and
Catawba Creek parts of the lake
Resources Impacted
Catawba Creek Crossing The Preferred Alternative corridor crosses Catawba Creek just south of the
Catawba Land Conservancy easement In the immediate vicinity of the Catawba Creek crossing there are
two wetlands (W246 and W248) and an intermittent stream (S280) that would be crossed by the Preferred
Alternative final design in addition to Catawba Creek Wetland W246 and most of wetland W248 would
be bndged Stream S280 would be in a culvert A small finger of the Lake Wylie project boundary (0 29
acres) along unnamed intermittent stream 5280 would be filled
The crossing is proposed to be dual bridge structures each with two travel lanes Temporary work budges
are proposed on both sides of the new bridges over Catawba Creek Vertical clearance over the full pond
elevation of Lake Wylie (569 4 ft MSL) is a minimum of 28 feet located at the west bank There would
be a total of 10 bridge bents within Lake Wylie at this crossing with a total area of 664 square feet
The permanent easement over Lake Wylie at the Catawba Creek crossing would be 1 69 acres The
temporary easement areas would be an additional 1 04 acres

would be 7 80 acres The temporary easement areas would be an additional 4 80 acres
The crossing area shoreline classification from the Duke Energy Corporation s Lake Wylie Shoreline
Management Plan is Public Infrastructure on the west bank and Impact Minimization Zone and Future
Residential on the east bank
Avoidance and Minimization
The NCTA has avoided and minimized impacts to water resources to the fullest extent practicable for the
entire Garden Parkway project The spans proposed at the three crossings span a width greater than the
FERC project boundary The bridges also are elevated above Lake Wylie with vertical clearances a
minimum of 28 feet This means there is room on either side of Catawba Creek South Fork Catawba
River and Catawba River for flood flows and terrestrial movement of wildlife which reduces and
minimizes the effects of interruption of habitat connectivity
HEP Compensation
The NCTA is committed to incorporating all reasonable and practicable design features to avoid and
minimize jurisdictional impacts However some impacts to fish and wildlife resources will occur for this
project within the FERC project boundary for Lake Wylie The NCTA proposes a payment of $180 339
to the HEP as compensation for impacts to habitat within the FERC Project Boundary

Environmental Documentation
The Draft Environmental Impact Statement (DEIS) for the Gaston East West Connector was signed and
released on April 24 2009 and can be found at http //www ncdot gov/pioiects/gardenparkway The
Final Environmental Impact Statement (FEIS) was signed and released on December 21 2011 and can be
found at http //www ncdot gov/projects/gardenparkway/ The Record of Decision (ROD) was signed and
released on February 29 2012 and can be found at http //www ncdot gov /protects/ ag rdenparkwa
Indirect and Cumulative Impacts
The 2009 Gaston East West Connector DEIS provided a qualitative analysis of indirect and cumulative
effects (ICE) A Quantitative Indirect and Cumulative Effects Analysis (Louis Berger Group Inc
August 2010) has been completed for the Preferred Alternative and the results of that assessment are
presented in the FEIS This Quantitative ICE Analysis closely followed 2001 guidance developed by the
NCDOT and North Carolina Department of Environment and Natural Resources (NCDENR) entitled
Guidance for Assessing Indirect and Cumulative Impacts of Transportation Projects in North Carolina
Volume H Practitioner s Handbook ( NCDOT & NCDENR 2001 a) The analysis relied on forecasts
developed by the local planning agencies Gaston Urban Area Metropolitan Planning Organization
(GUAMPO) Mecklenburg Union Metropolitan Planning Organization (MUMPO) and Rock Hill Fort
Mill Area Transportation Study (RFATS)
For the Quantitative ICE Analysis the No Build Scenario and Build the Preferred Alternative
Scenario (based on the refined preliminary design) were evaluated and compared to each other and to
existing conditions An interchange at Bud Wilson Road was originally proposed for the protect and
would have been considered as part of the protect when the demographic forecasting was being conducted
for the 2035 Long Range Transportation Plans The Preferred Alternative does not include this
interchange However this change does not have the potential to substantially alter the results of the
quantitative indirect and cumulative effects assessment since the removal of the Bud Wilson Road
interchange would not change the estimated basic pattern of the growth forecasts because numerous other
interchanges remain part of the design of the Preferred Alternative
Agency comments on the Draft EIS raised the following issues related to indirect and cumulative effects
water quality changes in impervious surfaces land use change indirect and cumulative loss of farmland
and habitat fragmentation The following sections summarize the incremental effects attributable to the
Gaston East West Connector for each of the issues addressed in the Quantitative ICE Analysis
Water Quality and Impervious Surface
Impervious surface cover is an accepted indicator for assessing the potential for water quality impact as a
result of future development Existing impervious surface cover in the ICE Study Area was assessed
using Feature Analyst a GIS program The resulting data was then manually edited based upon review of
2009 aerial photography Based on 2007 conditions approximately 12 5 percent of the ICE Study Area
consists of impervious surface cover Beaverdam Creek Upper Crowders Creek and Lower Crowders
Creek subwatersheds on the western side of the ICE Study Area consist of less than 10 percent
impervious surface cover The Paw Creek and Lake Wylie Catawba River subwatersheds on the eastern
side of the ICE Study Area exhibit the highest percent impervious cover at over 20 percent The
Attachment 1 l Page 1 of 9

Attachment 11— Environmental Documentation
U 3321 Gaston East West Connector (Garden Parkway)
remaining watersheds in the study area have a percent impervious cover within the range of 10 to 20
percent
To project future growth in impervious surface cover for the No Build and Build Scenarios percent
impervious surface factors from the Natural Resource Conservation Service (NRCS) TR SS Manual were
used A factor of 30 percent was used for residential development and a factor of 70 percent was used for
employment related development Impervious surface cover associated with the No Build Scenario
transportation projects was estimated based on the length of the project and the number of new travel
lanes specified in the LRTPs for the ICE Study Area
Future development under the No Build Scenario is expected to increase impervious surface cover by
over 10 000 acres compared to existing conditions for the ICE Study Area as a whole Impervious
surface cover within the ICE Study Area associated with the No Build Scenario is 19 3 percent The
Preferred Alternative would add approximately 500 acres of impervious surface cover to the ICE Study
Area with the largest increase (approximately 200 acres) in the Upper Crowders Creek subwatershed
Impervious surface cover associated with the Preferred Alternative right of way was estimated to be 19 8
percent Although some impacts would still occur the incremental water quality impacts of these shifts in
growth would be less than past growth due to the stormwater control and riparian buffer policies in the
study area
Long term impacts on water quality could be possible due to particulates heavy metals organic matter
pesticides herbicides nutrients and bacteria often found in highway runoff Prior to construction an
erosion and sedimentation plan would be developed for the Preferred Alternative in accordance with
applicable rules regulations and guidance including Design Standards for Sensitive Watersheds (15A
NCAC 04B 0124) the latest versions of the NCDENR publication Erosion and Sediment Control
Planning and Design Manual the NCDWQ s Stormwater Best Management Practices Manual (July
2007) and NCDOT s Best Management Practices for Protection of Surface Waters
Due to construction activities and the increase of impervious surface associated with the construction of a
mayor highway managing stormwater runoff is an important activity to reduce pollutant loads to adjacent
streams The NCTA would work with regulatory agencies to identify the best management practices
(BMPs) that would help ensure water quality is protected
Land Use Change
Mapping of existing land use in the ICE Study Area was developed based on GIS parcel data for Gaston
Mecklenburg and York Counties combined with spot checking against 2009 orthophotography Direct
land conversion resulting from the Preferred Alternative was accounted for using the Preferred
Alternative refined preliminary design right of way boundaries
Based on projected changes in households and employment the indirect land use effect of the project is
an approximately 1 5 percent increase in the total area of residential land and a 0 4 percent decrease in
employment related land in the ICE Study Area The largest absolute difference in land conversion
between the No Build and Build Scenarios is projected for the Catawba Creek subwatershed
Attachment 11 Page 2 of 9

Attachment 11— Environmental Documentation
U 3321 Gaston East West Connector (Garden Parkway)
Relative to the No Build Scenario the Build Scenano would generally increase growth in the zones along
the Preferred Alternative alignment in southern Gaston County and also in northern York County These
areas would experience an increase in relative accessibility that would all other factors held constant
make these zones more attractive for development as a result of the project Areas along the 185 corridor
would not experience as large of an accessibility improvement and as a result show less growth under
the Build Scenano than under the No Build Scenario The substantial growth projected for the southeast
portion of Gaston County (including the indirect land use effects of the proposed project) is largely
consistent with local plans for Gaston County For Mecklenburg County the analysis results show that
the proposed project does not substantially change the household and employment levels for the portion
of Mecklenburg County within the ICE study area
York County s 2025 Comprehensive Plan (April 2004) calls for rural residential and agricultural land use
in the northern portions of the county within the ICE study area with concentrations of commercial and
industrial land use along the US 321 corndor There is potential for substantial growth pressures without
the proposed project to be inconsistent with the objective of maintaining a primarily rural character in this
area The additional growth in this portion of York County with the proposed project would incrementally
add to this potential inconsistency
Farmland
As a subset of land use change indirect and secondary impacts to farmland were considered for analysis
Farmland was not ultimately selected as a resource for detailed analysis because farmland is not a mayor
land use throughout most of the ICE Study Area and there are methodological issues with distinguishing
active farmland from other types of open undeveloped land based on aerial photography However some
indication of the potential for impacts to agricultural land in the future can be obtained by review of the
projected land conversion associated with household and employment growth Specific impacts to
agricultural lands will depend on the decisions of individual land owners as influenced by land prices and
the economics of farming
Within Gaston County many of the agricultural areas are located in the northern portions of the county
that have not experienced substantial development pressures Therefore the existing proportional loss of
farmland in southern Gaston County is likely greater than the county level Census of Agriculture data
suggest due to suburban residential development associated with the growth of Charlotte A Voluntary
Agricultural District program began in Gaston County in 2004 with the objective of protecting and
conserving the agricultural open space
Habitat Fragmentation
Indirect impacts from the project could occur from forest fragmentation Forest fragmentation occurs
when large contiguous forests are divided into smaller patches by urbanization roads and agriculture
When habitat is fragmented the amount of edge habitat increases at the expense of interior forest habitat
Under these circumstances species dependent upon intenor habitat (such as many migratory or neo
tropical birds) suffer while edge dependent species including invasive species and predators thrive
Highly fragmented forests do not provide the food cover or reproduction needs of interior forest species
Attachment 11 Page 3 of 9

Attachment 11 — Environmental Documentation
U 3321 Gaston East West Connector (Garden Parkway)
The road itself could provide a physical barrier to the movement of mammals reptiles and amphibians
along wildlife corridors and from one forest patch to another
Forest cover and the size and configuration of undisturbed habitat blocks are key indicators for assessing
potential upland wildlife habitat impacts As with impervious surface cover existing tree cover was
defined using Feature Analyst and reviewed using 2009 aerial photography In addition to tree cover
impact assessment an analysis was performed to identify interior forest habitat and assess the direct
impacts and indirect edge effects of the Preferred Alternative For existing conditions in the ICE Study
Area an edge effect zone of 300 feet was created around existing roadways development and other open
areas (waterbodies agricultural fields etc) The edge effects of the Preferred Alternative were
superimposed on the existing conditions mapping to determine the incremental increase in edge effects
and habitat fragmentation impacts
Including urban trees approximately 59 percent of the ICE Study Area is currently overlain by tree cover
as of 2007 The highest percentage of tree cover occurs in the Upper and Lower Crowders Creek
subwatersheds (approximately 65 percent) while the lowest percentage occurs in the heavily developed
Paw Creek Lake Wylie subwatershed (38 percent) The majority of the forest interior habitat patches in
the ICE Study Area are small and there are only nine interior habitat patches greater than 500 acres in
size The largest habitat patches are located in and around Crowders Mountain State Park As expected
there are no large interior habitat patches remaining in the most heavily developed portions of the ICE
Study Area such as Gastonia
Under the No Build Scenario approximately 8 500 to 20 500 acres of tree cover could be lost as a result
of projected future development reducing the total percent forest cover in the ICE Study Area to
approximately 54 to 46 percent The Preferred Alternative refined preliminary design would directly
impact approximately 1 000 acres of tree cover 300 acres of which would occur in the Upper Crowders
Creek subwatershed The Preferred Alternative would directly impact 290 acres of forested interior
habitat and result in indirect edge effects potentially reducing the quality of an additional 480 acres of
forest interior habitat within approximately 300 feet of the right of way
The cumulative effect of past actions (e g existing tree cover) other actions (the No Build Scenario)
and the direct and indirect effects of the Preferred Alternative is predicted to result in remaining forest
cover in 2035 in the ICE Study Area of approximately 84 800 acres (low estimate of loss) to 71 400 acres
(high estimate of loss) This represents a cumulative loss of forest cover of approximately 22 900 to 9 500
acres over existing conditions or a percent decrease of 24 to 10 percent
The impacts of habitat fragmentation could be reduced by providing connections between habitats on
either side of the Gaston East West Connector In consultation with the NCWRC USFWS and USEPA
at a TEAC Meeting on April 8 2008 the NCTA identified a location along all Detailed Study
Alternatives (DSAs) where wildlife passage structures could be provided to maintain habitat connectivity
The installation of a wildlife passage at S 156 is a project commitment included in the Record of Decision
During final design the NCTA would coordinate with the NCWRC USFWS and USEPA on the design

of the wildlife passage at Stream S 156 and on designing bridge crossings to be wildlife friendly where
feasible
Protected Species
Species listed as Federally Endangered that occur in Gaston and/or Mecklenburg counties are Carolina
heelsplitter (Lasnugona decorata) Michaux s sumac (Rhus nuchauxii) Schwemitz s sunflower
(Helianthus schwienttzia) and smooth coneflower (Echinacea laevigata) (Table 14 below) Other
federally protected species are bald eagle (Haliaeetus leucocephaltts) protected under the Bald and
Golden Eagle Protection Act (BGEPA) and the Migratory Bird Treaty Act (MBTA) and bog turtle
(Cleininys nuthlenbergtt) listed as Threatened due to Similarity of Appearance
Biologists from NCDOT visited 28 potentially impacted streams within the Gaston East West Connector
corridor and based on what was observed conducted either a typical mussel screening (100 meters
upstream and 400 meters downstream) or a habitat assessment
Surveys for protected plant species were conducted within the DSAs in October 2005 by biologists from
Kimley Horn and Associates Environmental Services Inc HW Lochner and Earth Tech Inc Prior to
field investigations available mapping and aerial photography was reviewed to identify potential suitable
habitat for the protected plant species Biologists then conducted detailed field surveys for listed plant
species by walking transects through the identified areas of suitable habitat Results of the plant surveys
are detailed in the Protected Plant Species Surveys Gaston East West Connector Study (PBS &J 2006)
Surveys for Michaux s sumac and smooth coneflower failed to find any occurrences of these plants
Therefore no effect is anticipated to either species For Schweinitz s sunflower a population was located
south of Catawba Creek along the western side of SR 2435 (Union New Hope Road) This population is
approximately 1 0 mile north of the alignment for the Preferred Alternative Another known population is
located on Catawba Cove Road (SR 2650) approximately 1 0 mile south of the Preferred Alternative No
direct effect is anticipated to either of these populations Indirect and cumulative effects were not
analyzed for these species However for the three plant species the overall loss of forested cover and
increase in maintained areas may provide increased opportunities for colonization by these early
successional species
Consideration was given to the location of endangered species throughout the alternatives development
and design process Measures taken to identify species occurrences and avoidance and minimization of
impacts to these species are detailed below
Updated surveys for protected plant species were conducted for the Preferred Alternative in 2009 and
2010 and documented in a memorandum titled 2010 Plant Surveys in Gaston and Mecklenburg Counties
for the Gaston East West Connector (STIP U 3321) (PBS &J October 22 20 10) The updated surveys
did not locate any populations of the surveyed plant species within the Selected Alternative corridor
The U S Fish and Wildlife Service concurred with the biological conclusions in a letter dated June 12
2009 included in Appendix B 1 (letter a014) of the Final EIS Since no specimens of these protected

Hahaeetus leucocephalus Bald eagle
According to the National Bald Eagle Management Guidelines the bald eagle may have occurrences and
nesting habitat along the Catawba River An aerial survey for bald eagles was performed by helicopter on
December 19 2006 by Earth Tech Inc biologists The survey included the Catawba River/Lake Wylie
area within the Project Study Area and extending outward one mile Areas along the shoreline and
adjacent to the shoreline were surveyed for the presence of large nests Also areas with historical nest
data were surveyed thoroughly in an attempt to relocate the recorded nests Large nests identified during
the aerial survey were ground truthed on February 8 2007 by biologists using a spotting scope and
binoculars No eagle s nests were found within the project study area The closest observed eagle s nest
is about 1 6 miles north of the project study area It is likely that eagles forage for fish within the project
study area especially at Lake Wylie Continued coordination with the USFWS is recommended to insure
that provisions within the BGEPA and MBTA are met
Clemmys muhlenbergit — Bog turtle
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
A search of the NHP database did not reveal any occurrences of the bog turtle within the project study
area There is an occurrence of the bog turtle approximately 2 5 miles northwest of the DSAs in Gaston
County Two additional occurrences were recorded approximately 4 3 miles northeast of the DSAs

U 3321 Gaston East West Connector (Garden Parkway)
Lasmigona decorata Carolina heelsplitter
NCDOT biologists visited 28 streams that could be potentially crossed within the Gaston East West
Connector corridor on September 15 16 and 21 in 2005 Thirty sites on these streams were assessed
utilizing a standard freshwater mussel screening protocol or an assessment of mussel habitat Named
streams surveyed for freshwater mussels included Oates Creek Bessemer Branch Crowder s Creek
McGill Branch Mill Creek Myrtle Creek Catawba Creek and Beaverdam Creek No freshwater
mussels were found in any of the surveyed streams Because freshwater mussels were not found it is
concluded that the Carolina Heelsplrtter does not occur in the project vicinity The NCNHP does not list
any known population upstream 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 upstream or downstream
of the confluences of these streams It was concluded that the project will have no effect on this mussel
species
Rhus michauxu Michaux's sumac
Potential habitat for Michaux s sumac occurs throughout the project study area No populations of
Michaux s sumac were found during field 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 the field surveys the project will not directly
or indirectly impact any Michaux s sumac populations within the area surveyed This project will have no
effect on Michaux s sumac
Hehanthus schweinitzit Schweimtz's sunflower
The powerhnes roadsides and open areas within the project study area are high probability areas for
suitable Schwemitz s sunflower habitat These high probability areas were surveyed for the presence or
absence of Schwemrtz s sunflower in October 2005 One population of Helanthus schweinitzu was
observed within the project study area This population is located along the western side of SR 2435
(Union New Hope Road) All impacts to the observed Schwemrtz s sunflower population were avoided
by subsequent design and alignment refinements NCNHP records indicate that there is one known
Schweinitz s sunflower population about 4 900 feet south of the project study area (approximately 1 0
mile south of the Preferred Alternative) This population is located on SR 2650 (Catawba Cove Road)
approximately 3 650 feet northeast of the intersection of SR 2650 and SR 2431 (Rufus Ratchford Road)
I
Project related direct effects to Schwemrtz s sunflower will not occur Potential indirect effects such as
development subsequent to highway construction are unlikely but are anticipated to be avoided by on
site preservation and management
Echanacea laevigata Smooth coneflower
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 October 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 this
project will have no effect on any smooth coneflower populations

Critical Habitat
No Critical Habitat exists within or near the project corridor for any of the federally listed species
Flood Zone Designation
Named streams with defined floodplains in the Project Study Area include from west to east Abernethy
Creek Oates Branch Bessemer Branch Crowders Creek Blackwood Creek Ferguson Branch
(floodplam only) McGill Branch ( floodplain only) South Crowders Creek (floodplam only) Catawba
Creek South Fork Catawba River Catawba River Beaverdam Creek and Legion Lake Stream Several
unnamed tributaries of Crowders Creek and Catawba Creek also have defined floodplains Defined
floodways generally are located within or near municipal limits
For all new location crossings on Federal Emergency Management Agency (FEMA) regulated streams '
(streams where a floodway and /or floodplam has been identified) a Conditional Letter of Map Revision
(CLOMR) and Letter of Map Revision (LOMR) will be submitted to the N C Flood Mapping Program
for streams in Gaston County and to Charlotte Mecklenburg Storm Water Services for streams in '
Mecklenburg County
A preliminary hydraulics analysis (Final Preliminary Hydraidic Technical Memorandum for the Gaston
County East West Connector PBS &J December 2007) was performed to identify the preliminary sizes
and locations of mayor drainage structures along the DSAs that would be needed to adequately carry
floodwaters The Preferred Alternative includes 13 budge crossings over waters or wetlands and 44
culverts or pipes that are 72 inches or greater in diameter
Bridge structures include
• 1 bridge over S 14
• 1 bridge over W35 and S28 '
• 2 bridges (east and west bound) over S 135 & S 134
• 2 bridges (east and west bound) over S 146
• 2 bridges (east and west bound) over Catawba Creek (5259) and W246 '
• 2 bridges (east and west bound) over South Fork Catawba River*
• 2 bridges (east and west bound) over Catawba River*
• 1 bridge over W332* '
*These structures are included within the Final Design Section
The Selected Alternative will impact 100 year floodplains associated with Oates Branch Bessemer
Branch Crowders Creek Blackwood Creek Stream S 146 (unnamed tributary to Crowders Creek)
Catawba Creek South Fork Catawba River Catawba River Beaverdam Creek and Legion Lake Stream
There would be 10 crossings of floodways and 13 crossings of floodplains In addition there would be
one longitudinal encroachment of 1 400 feet (approximately 5 acres) along eastern edge of Crowders
Creek During final design of the Preferred Alternative a detailed hydrologic and hydraulic analysis
would be performed for each crossing location to determine the actual size and configuration of each
structure

1 In National Flood Insurance Program flood hazard areas the final hydraulic designs for the Preferred
Alternative would be such that the floodway would carry the 100 year flood without a substantial increase
in flood elevation The effect of the project on floodwaters could be mitigated effectively through proper
1 sizing and design of hydraulic structures

were determined based on the preliminary designs for each DSA
The Preferred Alternative has a No Effect determination for all of the properties identified within the
APE with two exceptions The Preferred Alternative has a No Adverse Effect determination to the JBF
Riddle House provided the shoulder width and ditch slope do not result in taking of property either by fee
simple or permanent easement In the refined preliminary design conditions are maintained for the No
Adverse Effect determination The shoulder width and ditch slope would not result in taking of property
from the JBD Riddle House
The Harrison Family Dairy Farm has a determination of No Adverse Effect provided that full access to
the property is maintained In the area near the Harrison Family Dairy Farm full access to the property is
maintained which means the conditions are met to maintain the No Adverse Effect determination As
with the Draft EIS preliminary design the refined preliminary design of the Preferred Alternative would
not require land from the Harrison Family Dairy Farm
Prehistoric Cultural Resources
An intensive archaeological survey was conducted for the Preferred Alternative The survey is
' documented in the Archaeological Survey and Evaluation of Detailed Study Alternative 9 (Recommended
Route) for the Proposed Gaston East West Connector (Coastal Carolina Research February 20 10) This
study is referred to in this section as the Intensive Archaeological Survey
The APE for the Intensive Archaeological Survey included the DSA 9 preliminary design right of way
ranging in width from 300 feet on the mainline comdor to more than 1 400 feet in some of the proposed
interchange areas Previously surveyed areas that required no further archaeological survey comprised
approximately 164 acres
' The North Carolina Office of State Archaeology (OSA) was consulted at a meeting on July 30 2009
prior to commencement of the surveys to review the approach and scope of the study The Intensive
' Archaeological Survey covered all previously un surveyed portions of the APE Areas that were
disturbed extremely sloped or low and wet were examined on foot but not intensely surveyed In
remaining areas shovel tests were conducted at appropriate intervals Recovered artifacts were processed
' and analyzed as described in the Intensive Archaeological Survey

Attachment 12 — Historic and Prehistoric Cultural Resources
U 3321 Gaston East West Connector (Garden Parkway)
Archaeological saes within the APE that appeared to retain significant deposits were investigated to
gather data on the sites dimension and artifact distribution presence or absence of subsurface features
site integrity and composition The testing was limited to the amount necessary to determine a site s
significance in terms of NRHP criteria
In a memorandum dated May 21 2010 the HPO concurred that no archaeological sites identified within ,
the APE are eligible for the NRHP The Intensive Archaeological Survey recommended that two sites
(31GS337/337 ** and 31GS365/365 * *) were potentially eligible for listing on the NRHP However '
based on an evaluation of the survey results HPO and FHWA concurred that these sites do not retain the
level of integrity nor do they possess the potential to yield significant new information pertaining to the
history of North Carolina Therefore these sites are not eligible for listing on the NRHP '
