MEETING HIGHLIGHTS: The Merger Team reviewed project information including project purpose and
need, unique project characteristics, environmental features, and recent Merger Team actions. The
team then reviewed major drainage structure locations and proposed designs.
The Merger Team reached agreement on CP2A (signature form attached). The following paragraphs
summarize the discussion items and conclusions reached at the meeting.
ITEMS OF DISCUSSION AND DECISIONS:
GENERAL ITEMS:
• It was noted that there are 15 major stream crossings and that most are WS-IV, Class B
Critical Areas. It was also noted that the Catawba River Basin Buffer Rules are applicable
for this project; requiring a 50-foot buffer along the main stem of the Catawba River
which includes Lake Norman.
• In addition to the six-foot paved shoulders that will be provided for bike and pedestrian
accommodations (except in the curb and gutter sections located in the urbanized
areas), a multi-use path is planned for a portion of the project. The EA will treat the
multi-use path as a modular component since the construction of this path is based on
funding availability.
• All alternatives include major stream crossings. Existing culverts are currently single barrel
culverts that will be replaced due to the age. There are four bridges common to all
three alternatives: Reed Creek, Mountain Creek, Marshall Steam Plant Discharge
Channel, and Lake Norman.
• NCWRC noted that baffles may need to be included based on what the culvert
dimensions are determined to be. NCWRC requested that the culverts be sized correctly
for wildlife passage, stream velocity, etc.
• * Need to note on CP 2A form that structural dimensions are preliminary and subject to
change based on refined designs and/or avoidance and minimization measures. (Note:
CP2A form was revised during the meeting to reflect this change)
MAJOR DRAINAGE STRUCTURE Discussion:
Site 1(West Fork Killian Creek): Alternatives 1, 2, and 4
- Hydraulics recommends replacing existing 90' long, 5'x5' RBC with a 7x7, 197' long
RCBC.
- Wetlands are adjacent to the culvert outlet. The Hydraulics Unit noted that water or
sewer lines on the downstream side that results in standing water on the upstream
side of the culvert, likely creating the adjacent wetland. Additionally, It was noted
that the downstream wetland has been degraded due to the recent clearing of
adjacent land.
- USFWS noted that the wetlands depicted in graphic don't seem to be completely
delineated. Stantec noted that the wetlands do extend beyond the boundaries
upstream, therefore the wetland boundary line was line was left "open" at the study
area boundary.

- USFS noted that the equilibrium pipe should be extended to maintain the wetland
connection. Note that the wetland is med-high rating (61 to 62).
Site 2(East Fork Killian Creek): Alternatives 1, 2, and 4
- Hydraulics recommends replacing the single-barrel, 53' long, 4x4 RCBC with a 181'
long, 6'x7' RCBC.
- It was noted that the corridor is undergoing rapid development.
Site 3(Reed Creek): Alternatives 1, 2, and 4
- The existing structure (Bridge #170012), is a 241' long bridge with a reinforced
concrete deck on precast pre-stressed concrete girders.
- Hydraulics recommends a parallel 241 ' long bridge north of the existing structure.
- Existing bridge is sufficient per NCDOT standards but does not meet Shoreline
Management Standards. It is assumed that this structure will need replacing by the
time the R-2307 project is funded.
Site 4(Mountain Creek): Alternatives 1, 2, and 4
- The existing structure (Bridge #170044), is a 301' long bridge with a reinforced
concrete deck on precast pre-stressed concrete girders.
- Hydraulics recommends a parallel 301 ' long bridge north of the existing structure.
- Duke Energy noted that the Shoreline Management Plan may be updated and that
this plan may dictate the elevation of the proposed structures. The existing bridge is
assumed to need replacement by the time the project is funded.
Site 5(Bettie Creek/UT to Bettie Creek): Alternative 1 Only
- Hydraulics recommends replacing existing 70' long, 5'x5' RCBC with a bx7, 245' long
RCBC.
- Roadway Design noted that the length of the proposed culvert is dictated by the
high fill in this section in order to obtain the design speed.
- USFWS noted concern with the amount of stream being placed into the culvert and
questioned whether a bridge would be more appropriate at the site. USFS asked if a
retaining wall could be utilized to reduce the culvert impact.
- Roadway Design noted that culvert is preferable to a bridge and that a replacement
bridge would be over a 100' long.
- Hydraulics noted that due to the urbanization around the project area, urban design
guidelines are being utilized for culvert sizing.
- USFWS stated that the culvert could go from an aquatic life passage to a blockage
due to the length of the culvert.
- Hydraulics asked if there was an acceptable culvert length that would not prohibit
aquatic life passage. They noted that the height of the culvert could be increased,
which would reduce the require culvert length. 2:1 slopes and a 25' high fill section
at the culvert location.
- USACE asked if the culvert could be moved to the west to reduce the length.

- USACE also noted that Stream SD is flowing into the main creek at the north end of
the existing culvert---asked how Stream SD will be modified to go through the
proposed culvert.
- Hydraulics noted that there is opportunity to reduce the culvert length to 200' by
increasing the culvert height.
- A pump station in located in the southwest quadrant of the culvert location.
- Hydraulics noted that the existing culvert is in a sag curve therefore the grade will be
raised to reduce the degree of sag. The 25' high fill facilitates a 60 MPH design. A
design exception would be required to increase the grade from 4�o max to 5�o max
and reduce fill slightly.
- It was noted that culvert length is not as important to streams being impounded by
the lake versus streams that are part of independent systems.
- USFWS noted the following impacts: 416' for Bettie Creek and 192' is for stream SD.
Action Item: NCDOT will evaluate potential modifications to the culvert dimensions and
vertical alignment to reduce culvert length.
Site 6(UT to Beaver Dam Creek): Alternative 1
- Hydraulics recommends replacing existing 45' long, 8'x9' RCBC with a 10'x10',
154'long RCBC.
Site 7(Discharge Channel): Alternatives 1, 2, and 4
- The existing structure (Bridge # 170117), is a 455' long bridge with a reinforced
concrete deck on precast pre-stressed concrete girders.
- Roadway recommends a new 450' bridge (westbound) and a new 600' bridge
(eastbound).
Site 8(Lake Norman): Alternatives 1, 2, and 4
- The existing structure (Bridge # 170138), is a 1162' long bridge with a reinforced
concrete deck on precast pre-stressed concrete and steel girders.
- Hydraulics recommends a l,l bb' bridge (westbound).
- Impacts to the boat landing near Site 8 are eliminated with a proposed 400' retaining
wall. NCDOT will coordinate with Duke Energy through the FERC permit process.
Site 9(UT to Reeds Creek): Alternatives 1, 2, and 4
- Hydraulics recommends replacing the single-barrel, 215' long, 60" diameter RCP with
a 300' long, 72" RCP w/ headwalls.
Site 10 (UT to Reeds Creek): Alternatives 1, 2, and 4
- Hydraulics recommends extending existing 139' long, 6'xb' RCBC to 219' in length on
the outlet end.
- Hydraulics noted that the flow is controlled by 70" diameter pipe under the car
dealership.
- Roadway Design noted that moving the U-turn bulb eastward to shorten the culvert
length would impact the in/right out into the business located in the SE quadrant.

• Site 11 (Reeds Creek): Alternatives 1, 2, and 4
- Hydraulics recommends replacing existing 169' long, 60" diameter CMP with a 213'
long, 72" diameter RCP w/ headwalls.
• Site 12 (Beaverdam Creek/UT to Beaver Dam Creek): Alternative 2 Only - North Terrell
Bypass (New Location)
- Hydraulics recommends constructing a 178' long, 8'x8'RCBC
- Downstream, along NC 150 is an existing 8'x9' RCBC (Site 6). Culvert would remain in
place.
• Site 13 (Bettie Creek): Alternative 4 Only- South Terrell Bypass (New Location)
- Hydraulics recommends constructing a 337' long, 7'x7' RCBC.
- Impacts to stream are approximately 837.5'.
- Downstream of Site 5
- NCWRC recommend reducing length of the culvert. Asked if a bridge could be
constructed at this location
- Hydraulics noted that the impacts include the meander of the stream. Also noted
that there are issues related to constructing a bridge at this site. There may be some
tangent to curve transition issue on the bridge structure due to the horizontal
alignment at that location and the fact that the bridge alignment would have to
span both Site 13 and another minor crossing.
• Site 14 (West Fork Beaverdam Creek): Alternative 4 Only- South Terrell Bypass (New
Location)
- Hydraulics recommends constructing two 175' long bridges over W. Fork Beaverdam
Creek.
- Hydraulics noted that the bridge setbacks would be set sufficiently beyond the lake
elevation of 760'.
• Site 15 (Beaverdam Creek/UT to Beaverdam Creek)
- Hydraulics recommends constructing a 271' long, 10'x10' RCBC.
- Downstream of existing 8x9 RCBC (Site b).
- Site also impacts a UT (non-JDJ that runs diagonal across the proposed alignment.
ALTERNATIVE 4 DISCUSSION
• Alignment
- Alternative 4 is a"reasonable" design but may not be "prudent". The horizontal
alignment is controlled by the southern boundary of the Terrell Historic District (HD).
- Minimal horizontal curve radii are being used to minimize impacts to properties south
of the Terrell Historic District.
- At Site 14, the alternative proposes two 175'long, curved bridges with a 42' vertical
clearance over a"finger" of Lake Norman to void suspected rock formations.
- The alternative will not have access control.

• Impacts
- Alternative 4 will result in 4 residential relocations and the removal of 4 sheds.
(Impact Table from Alt 4 Evaluation shows 3 residential relocation 2 sheds)
- There are 4 stream crossings, including 1 non-jurisdictional stream, associated with
Alternative 4. These crossings result in approximately 1,300 linear feet of jurisdictional
impacts, 125' feet of minor stream relocations, and approximately 1,000 linear feet of
parallel non-jurisdictional stream impacts. The high fill section (due to the presence
of rock) is a contributing factor in the amount of stream impacts.
- The Alternative also impacts a church recreational area.
- There are impacts to one high-voltage transmission tower.
- There are two FERC crossings not associated with the other alternatives.
- The Alternative's connection to Sherrills Ford Road results in a classification change
(to local collector)—requiring a larger minimum ditch width along Sherrills Ford. This
results in impacts to properties in the Historic District along Sherrills Ford Road.
• Comments/Discussion regarding Alternative 4
- FHWA stated that the alternative requires further study and an impact comparison
made between the alternatives to determine prudence.
- NCWRC questioned as to whether the merger team would need to revisit CP2 in
order to drop this alternative from consideration.
- FHWA stated that the Merger Process allows for the elimination of an alternative after
CP2 once a"detailed study" has determined that it is no longer a"reasonable" or
"prudent" alternative.
- USFWS noted that this alternative was carried forward as a detailed study alternative
however, these detailed studies may show that this alternative is not prudent.
- PDEA stated that the current CP 2A Concurrence Form would need to be revised if
the alternative is going to be dropped. It was also noted that if the alternative can
be eliminated before the EA is completed then it does not have to be presented at
the Public Hearing. USFWS stated that there is concern with this alternative due to
the lack of access control due to potential indirect effects.
- NCWRC asked if Alternative 1 viable due to the presence of historic buildings in NW
and SW quadrants. PDEA stated that going through Terrell is feasible. Based off of
current conditions, the sidewalk would impact the front porch of the Gabriel house
and the Terrell Country Store. Visual integrity of the district is likely to be impacted by
the bypass alternatives due to no access control.
Action Item: NCDOT will provide a summary of Alternative 4 documenting that
detailed studies were completed for the alternative. The summary will include cost
estimates and preliminary impacts (include minor stream impactsJ in a matrix
comparing Alternatives 1, 2, and 4. Also, it needs to note the impacts associated
with the alternatives. It should also include a narrative of the issues related to
Alternative 3 (which was droppedJ.
