Merger Process Concurrence Point 2a - Bridging Decision Information -
NCTA'S Response to Agency Requests from the March 4, 2008 Meeting
A TEAC Meeting for the proposed Gaston E W Connector was held on March 4 2008 The purpose of
the meeting was to achieve agreement /concurrence on the bridging decisions for streams and wetlands
crossed by the Detailed Study Alternatives (Concurrence Point 2a)
Action items from that meeting addressed in this memo are listed below Discussions of these items are
provided in this memorandum along with NCTA s proposed action regarding each of them
ACTION ITEMS FROM THE MARCH 4, 2008 TEAC MEETING
Requests for additional bridges and for wildlife crossings
in addition to the additional bridges already agreed to during the CP2a meeting (Crossings HD27 HD32
HD17 and HD48) the NCTA was to consider the following
1 NCTA will consider providing wildlife passage structures at JD6 JD19 and JD31
2 NCTA will consider the additional bridging recommendations made during the meeting These include
changing a culvert to a bridge for Crossing JD9 and extending the bridges at J132 KD3 /KD17 to span
high value /high quality wetlands
Request for additional cost estimate
3 NCTA will prepare a cost estimate for Crossing H131 for extending /providing bridges over Crowders
Creek for the mainlines WB on ramp loop and WB off ramp to span Wetland 12
Requests for alignment shift investigations and other design changes
During the March 4 2008 TEAC meeting NCTA agreed to evaluate the feasibility of eliminating the
US 29 74 interchange for all DSAs The NCTA will present this concept to the public at the citizens
information workshops tentatively scheduled for this summer and will work with the Gaston Urban Area
MPO to receive their input on the potential interchange elimination A final decision on the removal of
this interchange would occur after the Preferred Alternative is selected and additional traffic and revenue
studies are performed The potential elimination will be discussed in the DEIS
In addition to the potential elimination of the US 29 74 interchange the agencies requested NCTA to
evaluate the following design changes
NCTA to consider eliminating the Corridor Segment H1A /US 29 74 interchange ramp that provides
access from US 29 74 to WB Connector This ramp crosses over W 12

5 NCTA will investigate the feasibility of shifting alignments at the following locations
a) Mainline shift at HB3 east to avoid W51
b) Mainline shift at JD17 to avoid parallel impacts to S146
c) Mainline shift at KD3 to avoid the easternmost finger of W248
d) Y line shift at KD31 to avoid confluence of Beaverdam Creek and Legion Lake Stream
DISCUSSION OF ACTION ITEMS AND NCTA'S RECOMMENDATIONS
1 CONSIDER PROVIDING WILDLIFE PASSAGE STRUCTURES AT JD6, JD19 AND JD31
The NCTA agrees to consider wildlife passage structures at these crossings during final design if they are
part of the Preferred Alternative This will be included as a commitment in the DEIS
• Crossing JD6 is crossing of Stream S156 on Corridor Segment J1C (west of Robinson Rd)
• Crossing JD19 is a crossing of Stream S156 on Corridor Segment JX1 (west of Robinson Rd)
• Crossing JD31 is a crossing of Stream S 156 on Corridor Segment J2C (west of Robinson Rd)
2 CONSIDER ADDITIONAL BRIDGING BEYOND WHAT IS REQUERED FOR HYDRAULIC
CONVEYANCE
The additional bridges already agreed to during the CP2a meeting are listed below
• Crossing HD27 is a crossing of Bessemer Branch located along Corridor Segment 1-12A It is on a
service road between 185 and US 29 74 The structure will be changed from a triple 7 x10 box
culvert to a bridge
• Crossing HD32 is a crossing of Stream S70 adjacent to Chapel Grove Road along Corridor Segment
H2C The structure will be changed from a triple 7 x10 box culvert to a bridge The bridge will be
an extension of the mainline crossing bridges over Chapel Grove Road
• Crossing HD 17 is a crossing of Stream S79 adjacent to Camp Rotary Road along Corridor
Segment HX2 The structure will be changed from a double 8 xl0 box culvert to a bridge
The bridge will be an extension of the mainline crossing bridges over Camp Rotary Road
• Crossing HD48 is a crossing of Stream S135 (Blackwood Creek) along Corridor Segment
H3 The structure will be changed from a triple 1 1 x10 box culvert to a bridge
As agreed to in the March 4 2008 TEAC meeting NCTA considered the following changes to the recommended
major structure and NCTA agrees to make all the bridging changes requested These are listed below
• Crossing J132 is located across Crowders Creek along Corridor Segment J3 west of US 321 NCTA
will extend the mainline bridges to span Wetland 103 in addition to Crowders Creek
• Crossing JD9 is a crossing of Stream S178 on Corridor Segment J1C (west of Bud Wilson Rd)
NCTA will change the recommended structure from a triple 7 x10 box culvert to a bridge

I Memorandum —March 13 2008
Gaston East West Connector STIP Project U 3321
• Crossings KD3 and KD17 are bridge crossings of Stream S259 (Catawba Creek) along Corridor
Segment K3A (x ing KD3) and Corridor Segment KiB (x ing KD17) NCTA will extend the bridges
over Catawba Creek at these locations to span the main body of Wetland W248 in addition to
Catawba Creek
3 COST ESTIMATE FOR BRIDGE AT CROSSING HB1
Mayor Hydraulic Crossing HB 1 is located at Crowder s Creek dust south of US 29 74 along Corridor Segment
HIA The alignment in this location is constrained to the east by a new public elementary school directly to the
east on the north side of US 29 74 and by the presence of the existing 185 /Edgewood Road interchange To the
west is a small subdivision with a church on the north side of US 29 74 South of US 29 74 there is a perennial
stream (S17) parallel to the alignment that would be impacted by a shift to the west Amore drastic shift to the
west could result in impacts to Crowders Mountain State Park and the confluence of Crowders Creek with
Abernethy Creek
There was a general discussion about the need for this interchange on any of the Detailed Study Alternatives
(DSAs) Currently the interchanges proposed along the Connector are consistent with the interchanges proposed
in the Long Range Transportation Plan The Gaston MPO stated they could consider eliminating this interchange
depending on the forecasted traffic volumes The NCTA will review all interchanges for the Preferred
Alternative and additional traffic and revenue studies will be completed for the Preferred Alternative to determine
if any should be eliminated
Wetland 12 (4 2 acres in size with a rating of high quality) is located between US 29 74 and Crowders Creek in
the center of the proposed alignment of Corridor Segment H1 A The resource agencies stated this wetland
provides an important function for maintaining water quality in Crowders Creek and impacts should be avoided or
minimized The agencies requested a cost estimate for bridging the wetland if it is feasible to do so from a design
perspective

As shown in the graphic bridges
that would span Wetland W12 are
shown in red The loop bridge
would be about 40 ft wide and
530 ft long The ramp bridge
would be about 60 ft wide and
275 ft long The mainline bridges
spanning Crowder s Creek and
Wetland W12 would be about 60
ft wide and 905 ft long each In
2007 dollars the total cost of
these new bridges would be $15 5
million The original cost
estimate for shorter mainline
bridges was $2 1 million If the
interchange is eliminated the cost
of the extended mainline bridges
(no ramps) would be $11 4
million

Memorandum — March 13, 2008
Gaston East -West Connector - ST /P Project U -3321
Recommendation. The NCTA recommends not including the additional bridging over Wetland W 12 due to the
large cost increase ($2.1 million vs $15.5 million with an interchange or $11.4 million without the interchange).
4. CONSIDER ELIMINATING THE US 29 -74 INTERCHANGE RAMP THAT PROVIDES
ACCESS FROM US 29 -74 TO WB CONNECTOR FOR CORRIDOR SEGMENT 111A
Recommendation. The NCTA will evaluate eliminating this ramp after the Preferred Alternative is selected
and additional traffic and revenue studies are performed.
5. ALIGNMENT SHIFT INVESTIGATIONS
a. Mainline shift at HB3 east to avoid W51 (,0
Major Hydraulic Crossing HB3 is located at Crowders Creek, just south of US 29 -74 along Corridor Segments
H2A and H3. The alignments in this location are constrained north of US 29 -74 by the presence of the
I- 85 /Edgewood Road interchange, Bessemer Branch to the west, and the existing 1 -85/NC 274 (Bessemer City
Road) interchange to the east. Also, in this area are moderate - income, minority communities located on both
sides of Shannon Bradley Road north of US 29 -74.
-4-
There are three junkyards in this area of
US 29 -74 identified as Sites 18 (Putnam
Auto Body), Site 19, and Site 20 in the
GeoEnvironmental Impact Evaluation
Memorandum ( NCDOT, 1/28/08). The
NCDOT identifies these as having low -
medium impact. Medium impact means
additional costs and time may be incurred
by the project due to handling of
contaminate materials and a need for
special construction techniques and /or
products.
The alignment was placed to minimize
relocations in these minority communities
and minimize encroachment into the
junkyards. The current preliminary
designs impact only Site 19, with a minor
encroachment into the Putnam Auto Body
junkyard.
The agencies requested that a shift in
Corridor H3 be investigated to move H3 to
the east to have the ramps avoid Wetland
51.

Memorandum — March 13, 2008
Gaston East -West Connector - STIP Project U -3321
In order to avoid Wetland 51, the interchange for Corridor Segment H3 would need to be shifted about 240 feet to
the east. This would encroach directly on the Putnam Auto Body junkyard and also would increase impacts to
Stream S54 from 188 if to about 575 If.
If the interchange at US 29 -74 is eliminated, no impacts would occur to Wetland W51 under the current
preliminary design.
Recommendation. NCTA recommends not shifting the alignment at this time since the current alignment
minimizes impacts to hazardous materials sites and the NCTA will evaluate eliminating the interchange altogether
(which would eliminate the wetland impact).
b. Mainline shift at JD17 to avoid parallel impacts to S146
Major Hydraulic Crossing JD17 is located on Stream S146, just west of US321 along Corridor Segment J 1 B. The
proposed crossing is a bridge over S146. The alignment in this location is constrained by the proposed
interchange at US 321, the existing rail line and businesses along US 321, the streams in the area, and the ACC
Industrial Park to the south of the alignment.
Alignment shifts to the north and the south were investigated. These are the purple lines in the first two graphics
below. The third graphic showing the yellow corridor boundary provides a better view of the environmental
features in the area.

An alignment shift to the north
would result in parallel stream
impacts to the entire lengths of
S138 (4,550 linear ft) and 5150
(1,700 linear ft). At the TEAC
meeting, the agencies did not
support a shift to the north.
An alignment shift to the south
would impact the northern half
of the ACC Industrial Park
(about 10 parcels), would
create a much less desirable
skew for the interchange at US
321, and would place the
southern interchange ramps
closer to the curve in US 321. These were the primary constraints in determining the placement of the current
preliminary engineering design. In addition, an alignment to the south would avoid Wetland W134 (0.5 acres),
but impact all of Wetland W131 (0.1 ac) and Wetland W132 (0.3 ac). Additional impact also would occur with
the reconnection of Crawford Road (shown near the red square in the third graphic). The Crawford Road
reconnection would need to be extended southeast around a residential subdivision to maintain its spacing from
the interchange ramps.
t
The southern realignment also would move the mainline alignment and ramps for the Robinson Road interchange
on to or near the confluence of Stream S 156 and Stream S 163.
Recommendation. NCTA recommends not shifting the alignment to the north at this time due to a substantial
increase in stream impacts. NCTA recommends not shifting the alignment to the south at this time because it
would create a less desirable interchange design at US 321, it would impact approximately 10 parcels in the ACC
Industrial Park (currently avoided) and the increased cost and impact of extending the Crawford Road
reconnection.

c. Mainline shift at KD3 to avoid the
easternmost finger of W248
Catawba Creek is a 303d listed stream.
The KD3 crossings of Catawba Creek are
located at the southern tip of the Catawba
Land Conservancy easement property.
Wetland 248 is a 4.76 acre high - value,
high - quality wetland. At the March 4,
2008 TEAC meeting, the USACE stated
this is the second of the two highest value
wetlands in the study corridors (the other
is at Crossing .1132). The floodplain limits
for Catawba Creek include this wetland.
The USEPA and NCWRC also thought
this was a high value wetland that should
be bridged. The resource agencies,
including the USACE, requested that the
bridge be extended to include the

Memorandum — March 13, 2008
Gaston East -West Connector - STIP Project U -3321
Catawba Creek floodplain and Wetland 248 due to the large size and high value of this wetland adjacent to a 303d
listed stream.
The agencies requested that the NCTA investigate the feasibility of shifting the alignment for Corridor Segment
K3A north to avoid the easternmost finger of W248.
In order to avoid the eastern finger of Wetland W248, Segment K3A would need to be shifted north about 300
feet. This shift would encroach on the Catawba Land Conservancy easement (shown in salmon on the graphic).
The shift would pass through W244 (.06 ac), S279 (intermittent stream, 320 linear ft), W245 (0.59 ac), W249
(0.18 ac), and W252 (0.29 ac). With a bridge over Catawba Creek on this realignment, W252, W244 and S279
likely would still be impacted. Some impacts to W245 also likely would occur, and W249 likely could be
spanned.
Recommendation. The NCTA recommends not
shifting the alignment at this time since the NCTA
has committed to bridging the main body of
Wetland W248 as part of the current alignment, and
the shift would encroach on Catawba Land
Conservancy lands. 44�

d. Y -line shift at KD31 to avoid confluence of Beaverdam Creek and Legion Lake Stream
Major Hydraulic Crossing KD31 is a y -line crossing (Dixie River Road realignment) of Beaverdam Creek for
Corridor Segment K4 east of Catawba River. The y -line realignment is adjacent to the north side of the existing
Dixie River Road crossing of Beaverdam Creek. It appears to be located at the confluence of Beaverdam Creek
and Legion Lake Stream. Dixie River Road was realigned in this area to create a better angle heading into the
interchange area to the north. The realignment was located to the north due to maintenance of traffic issues.
A shift of the Dixie River Road realignment to the south was investigated. The centerline of this shift is shown in
purple in the graphic below.
-7-

Memorandum —March 13, 2008
Gaston East -West Connector - STIP Project U -3321
A shift to the south would have greater maintenance of traffic issues, but would still be constructable. However,
with this alignment, the radius causes the superelevation of Dixie River Road to be at its maximum allowable
(0.08), which is not a desirable situation to create at this stage of design. This realignment could be revisited if
this alternative is selected as the Preferred Alternative and more refined mapping is available.
Recommendation. The NCTA recommends that the alignment not be shifted at this time because it would result
in a maximum allowable superelevation at the preliminary design stage. The NCTA recommends that this
alignment, if it is selected as the Preferred Alternative, be revisited during final design when more refined
mapping is available. 0

Merger Process Concurrence Point 2a - Bridging Decision
Information
In accordance with NCDCIT guidelines on information to be presented at a Concurrence
Point 2a meeting the following tables are attached
Hydraulic Table — This table includes the crossing ID streams /wetlands /ponds
crossed stream /wetland /pond impacts existing structures recommended
preliminary hydraulic structure size estimated cost and for selected crossings
the cost if the crossing was bridged
2 Existing Stream Characteristics — This table lists the characteristics of streams in
the study corridor boundaries including intermittent /perennial bank height
average width and depth substrate water quality classification and NCDWQ
score
3 Stream Impacts — This table lists the stream impacts by DSA
4 Existing Wetland Characteristics — This table lists the characteristics of wetlands
in the study corridor boundaries including wetland size Cowardm
classification NC DWQ rating and wetland quality rating
5 Wetland Impacts — This table lists the wetland impacts by DSA
Maps available to aid in discussions include
1 11x17 overview map showing the locations of recommended major preliminary
hydraulic structures
2 A set of 11x17 maps (23 sheets per set) showing the preliminary engineering
designs corridor boundaries surveyed streams /wetlands /ponds major
roadways recommended major preliminary hydraulic structures (labeled with
ID structure size and impacts to wetlands and streams) The purpose of this
map set is to be able to readily see each wetland and stream crossing of the
preliminary engineering designs

J
3 A set of 11x17 maps (23 sheets per set) with all environmental features displayed
along with the other information listed in item 2 above
4 A set of 11x17 aerial photographs (35 sheets and a key sheet) with the
preliminary engineering designs
5 A large scale Environmental Features Map with the corridor boundaries
preliminary designs and recommended major preliminary hydraulic crossings
Spotlighted Major Hydraulic Crossings
Due to the large size of the project NCTA implemented a methodology to focus on the
major hydraulic crossings to be discussed at the CP2a meeting The approach
summarized below resulted in the identification of the following forty (40) crossings
proposed to be spotlighted at the March 5 2008 TEAC Meeting
• Bridge Locations There are seventeen (17) crossings having a bridge as the
recommended preliminary crossing structure based on hydraulic considerations
(Note that in the February 5 2008 TEAC Meeting 20 bridge crossings were
mentioned This included bridge crossings for Corridor Segment K1D which
has been eliminated from further study)
• Triple Box Culverts There are six (6) crossings having a triple box culvert as the
recommended preliminary crossing structure based on hydraulic considerations
• High Quality Wetland Crossings Twelve (12) high quality wetlands are
crossed by the preliminary engineering designs Of these twelve six (6) are not
at a recommended bridge or triple box culvert location (crossings already
identified in the bullets above) and were added to the list of crossings to be
discussed
• 303d Listed Stream Crossings Each crossing of a 303d listed stream that has a
major hydraulic structure recommended will be discussed Within the project
study area three water resources Abernethy Creek Catawba Creek and
Crowders Creek are designated as biologically unpaired water bodies regulated
under the Final 2006 provisions of the Clean Water Act (CWA) 303(d) (NCDENR
2006b) Abernethy Creek is not crossed by the proposed preliminary engineering
designs Crossings of Catawba Creek and Crowders Creek are recommended to
be bridges so they are included in the list of crossings to discuss
• Major Non Bridge Crossings Each major non bridge crossing not already
included from the bullets above was reviewed by the project s engineering team
to identify those where a bridge may be more cost effective than the culvert or
pipe recommended for hydraulic purposes The engineering team used
engineering judgment and review factors such as the height of fill at the crossing
2

the existing topography potential length of a bridge and the length of stream
impact to identify locations where a cost comparison should be conducted
Based on these criteria eleven (11) crossings were identified for discussion
These included two (2) crossings near y line grade separations where an
extension of the grade separation bridge to clear the stream was evaluated and
nine (9) crossings that were double box culverts over streams with NCDWQ
ratings of 40 or greater
Additional information for the forty spotlighted crossings is provided on the following
