RE: Pre-Construction Notification: Nationwide Permit 12 and General Certification 4133
North Wilkesboro Sewer Improvements
Wilkes County, North Carolina

Dear Mr. Elliot:

Carolina Ecosystems, Inc., on behalf of the Town of North Wilkesboro and Municipal
Engineering, and in response to NCDWR review comments raised during review of this project,
has revised this cover letter and attached a revised Pre-Construction Notification (PCN) for the
above referenced project for a Clean Water Act Section 404 Nationwide Permit 12 and a Section
401 Water Quality Certification No. 4133.

The North Wilkesboro Sewer Improvement project would be installed through primarily
residential areas. The corridor is located along unnamed tributaries of Fishing Creek in
southwestern North Wilkesboro. The project would help to meet the growing sewer demands for
residences in the North Wilkesboro area of North Carolina.

The attached PCN form provides information for your use in review of unavoidable impacts to
streams and wetlands. Per request, full size plan sets are also being provided. Stream SA is the
dominant perennial feature flowing from south to north along and adjacent to the project. It is an
unnamed tributary of Fishing Creek in the Yadkin Pee-Dee River Basin. All other features on the
site eventually flow to Stream SA.

Construction would be accomplished using typical equipment including excavators, backhoes,
and other equipment as required. Erosion and Sediment controls would be installed during initial
site preparation. Trench boxes would be utilized in excavations where depth and proximity to
streams require shoring up trench walls for protection of both workers and adjacent resources.

All open cut stream crossings would utilize a temporary pump around and coffer dam to avoid
downstream sedimentation during installation (details are provided on the attached impact
figures). All stream crossings would be crossed at as close to perpendicular angles as possible
and utilize bridge mats to facilitate construction vehicle movement without impact to streams.
Bridge mats would remain in place until all downstream work has been completed and disturbed
areas are stabilized.

Avoidance and Minimization

A total of 12 wetland impacts, totaling .73 acre are associated with this property. Permanent and
temporary impacts total 0.25 and 0.48 acre, respectively. The permanent impacts include forested
wetlands that would be permanently converted to maintained/herbaceous wetland. A total of 12
stream impacts (11 sewer line crossings and 1 temporary ford crossing) totaling 239 feet, occur
within the proposed corridor. The attached PCN form provides information for use in your
review of the impacts to streams and wetlands associated with this site.

Proposed Impacts and Mitigation

This project was designed to parallel existing utility and transportation rights-of-way to the
maximum extent practicable. The below discussions are based on impact locations depicted on
the attached Plan and Profile project design sheets. Station numbers are approximate and
intended to inform the below discussions only. Impacts are reported as linear feet (l.f.) and acres
(ac).

Temporary coffer dams and pumping to prevent downstream sedimentation would be utilized for
all open-cut stream crossings and bridge mats, where needed, would enable vehicular crossings
with no impact below ordinary high water. Along portions of the alignment where distance from
stream channels cannot be increased, trench boxes will be utilized to shore trench walls, and
contractors will be instructed to work during low flow periods with no precipitation in immediate
forecasts. Silt fencing would enclose all work areas, and outlets would utilize straw wattles to
retain sediment on-site. Anti-Seep collars are provided at the downslope edge, and every 150-
feet upslope within wetland areas, to prevent inadvertent draining. Wetland impacts reported as
temporary are for either temporarily cleared forested areas, or pre-project herbaceous features
where no permanent conversion of forested resources would result. Wetland impacts reported as
permanent are for pre-project forested features where permanent conversion for inspection and
maintenance are necessary. Plan sheets include a note for the contractor that corridor widths
change in wetland areas.

Sewer Outfall 1

0+50 to 1+00: The temporary construction corridor would occupy areas within ten feet of the
stream bank. This area is depicted on MESCO Plan Sheet C-1. The NCDOT requests these
crossings be no less than 70 degrees. A bore and jack under speedway road and receiving bore
pit on the south side of speedway road necessitate this placement. The contractor will be required
to ensure all areas are properly shored to prevent collapse or exposure. Moving further from the
creek for this crossing would also make the first stream crossing (2+50), already protected with
concrete encasement, even more shallow.

2+40 to 2+60: A near perpendicular crossing of Stream S1 (38 l.f. temporary impact) would be
installed. The angle of this crossing is fixed due to the location of the tie-in to the North
Wilkesboro existing system at 0+00. Increasing the angle would require construction within a
wetland and close to Stream SA. This area is shown on CEI figure 3, sheet 1 of 7, and MESCO
Plan sheet C-1. A coffer dam and pump around would be utilized (Detail on Sheet D-1A). A
concrete encasement (Detail on Sheet D-3) would be utilized below the stream to protect the pipe

North Wilkesboro Sewer Improvements Page 3 of 7
May 23, 2018

due to the shallow depths required in this location. Portions of Wetland W1 (<0.01 ac.) and W2
(<0.01 ac.) would be temporarily cleared for construction between 2+60 and 2+80.

4+00 to 4+80: Wetland impact W3 is shown on CEI figure 3, sheet 1 of 7, and MESCO Plan
sheet C-1. This feature expands into a much larger wetland system area and is situated in the
floodplain between two streams (SA and SC). The crossing would require 0.03 ac. permanent
conversion from forested to herbaceous wetland, and temporary conversion of 0.03 ac.

8+00 to 11+50: Several areas along this reach would include overlap between the temporary
construction corridor and a 10-foot setback from the topographic stream bank. Project designers
attempted to balance wetland impact with stream avoidance in this area. Also, banks shown are
topographic breaks (where the geomorphic top of bank meets its floodplain). Proximity
calculations are protective and generally overstated. The jurisdictional top of bank is further from
construction in most cases. Wetland impact W4 (10+40 to 10+60) would require temporary
impact (0.01 ac.) and permanent conversion of forest to herbaceous wetland (<0.01 ac).

13+40 to 13+50: A near perpendicular stream crossing, S2, would be installed with use of a
coffer dam and pump around, and bridge mat, and require 33 linear feet of temporary impact.
This area is depicted on CEI figure 3 (1 of 7), and MESCO Plan Sheet C-2. The location of this
crossing places it near an abrupt turn in its channel. This is because historic land uses in this rural
residential area turned and straightened the feature along an existing tree line. Adjusting this
crossing to avoid the parallel overlap would bring it closer to the natural channel of the main
stem.

18+50: A stormwater ditch flows across the project corridor. This feature becomes a stream west
of the corridor (indicated by bolded bank lines on MESCO Plan Sheet C-2), but will not be a
surface water impact. Engineers are proposing a bridge mat and pump around to ensure
protection of this area due to its proximity as a precaution.

20+00: A lateral tie in is proposed from the west. This crossing is shown on Sheet C-8 as part of
Sewer Branch 1.

28+50 to 30+50: Wetland crossing W5, shown on CEI Figure 3 (2 of 7), and MESCO Plan Sheet
C-3). The crossing, of an herbaceous wetland in a field, would require 0.1 ac of temporary
impacts. No permanent conversion would result. Anti-seep collars are proposed at the
downstream end of this wetland, and every 150-feet upslope. This wetland was identified during
PCN interagency review to be marginally suitable for Southern Bog Turtle (threatened due to
similarity of appearance to northern bog turtle) by the NC Wildlife Resources Commission. CEI
will be on-site during construction of this segment to ensure no turtles are inadvertently harmed
during installation.

38+25 to 41+75: Wetland W6 and stream S4, depicted on CEI Figure 3 (3 of 7), and MESCO
Plan Sheet C-4. A perpendicular tie-in coming from the west, ties into the corridor at station
number 38+60. This tie-in would cross SA at a perpendicular angle, and cross through wetland
WE. This tie-in would be constructed by others, and its location and impacts are subject to
change. To construct this project, Wetland WE would require 0.21 ac of temporary impact and

North Wilkesboro Sewer Improvements Page 4 of 7
May 23, 2018

0.09 ac of wetland conversion. Anti-seep collars are proposed at the downslope extent and every
150-feet upslope within the wetland.

44+82 to 46+57: Jack and Bore crossing, CEI Figure 3 (4 of 7) and MESCO Plan Sheet C-4.
The original design called for a 100-ft Bore-and-Jack crossing, but included a receiving pit
adjacent to a stream channel and additional stream and wetland impacts would have been
required. Based on NCDWR review comments, the length of bore-and-jack was increased an
additional 75-ft and would now extend below three streams (S5, S6, and S7) and two wetland
areas (W7 and W8) with no impact to these resources.

46+80 to 49+10: Wetland Impact 9, CEI Figure 3 (4 of 7) and MESCO Plan Sheets C-4 and C-5.
Because of the relocated jack-and-bore receiving pit discussed above, impacts to Wetland 9 (CEI
Figure 3 (4 of 7) and MESCO Plan Sheet C -5) have changed slightly. This crossing would now
require temporary impacts to 0.1 ac. and permanent conversion of 0.04 ac.

50+25 to 51+60: Wetland Impact 10, CEI Figure 3 (4 of 7) and MESCO Plan Sheet C-5. This
crossing would require 0.04 ac of temporary impacts and result in 0.06 ac of conversion. This is
a slight change from the previous design due to a realignment associated with the revised jack-
and bore discussed above. Balancing stream avoidance with wetland impacts while preserving
the availability for future connections on both sides of the stream limit the options for this
wetland crossing. Anti-seep collars are proposed at the downslope boundary of this feature.

55+10: Stream crossing S8, CEI Figure 3 (4 of 7) and MESCO Plan Sheet C-5. A perpendicular
crossing of SE, would require 33 lf of temporary impact. A Ford would be constructed at this
crossing, over the sewer to share the unavoidable disturbance footprint to enable maintenance
access. A coffer dam and pump around would be utilized during construction (Drawing D-1A,
sheet 30 of 36). Details on the unavoidable ford impacts can be found on (Drawing D-1, Sheet 30
of 36).

68+00 to 69+20: The construction easement would be within 10-feet of the existing top of bank
in a couple locations along this reach (MESCO Plan Sheet C-6). There is no flexibility to avoid
this area due to an existing recreational facility show on the plan sheets. Project designers are
requiring contractors to perform work in this area during dry periods with no rain in the
immediate forecast. Trench boxes would be used during construction and would provide
stabilization against bank collapse.

70+50: Stream crossing S10 (CEI Figure 3 (5 of 7) and MESCO Plan Sheet C-6). A
perpendicular crossing would require 35 lf of impacts. A coffer dam and pump around and
bridge mat would be utilized at this crossing to avoid adverse impacts to the stream and its
banks.

77+00 to 78+25: Wetland crossing W11 (CEI Figure 3 (5 of 7) and MESCO Plan Sheet C-7).
The corridor would cross this herbaceous wetland. This property was recently constructed as a
residential yard and is disturbed. Proximity to the stream is necessary to maintain access to
service connections on both sides of NC 115, resulting in 0.08 ac of temporary impact.

North Wilkesboro Sewer Improvements Page 5 of 7
May 23, 2018

79+25: East of the residential home’s driveway, outside the study area, an intermittent stream
enters an 18” corrugated metal pipe and discharges at the bank of the main channel along NC
115. This pipe would be replaced immediately after construction and no permanent impact would
result.

83+60 to 84+00: The construction easement would be within 10-feet of the existing top of bank
near a meander bend. There is no flexibility to avoid this area due to the steep slope adjacent to
the line on the east. Project designers are requiring contractors to perform work in this area
during dry periods with no rain in the immediate forecast. Trench boxes would be used during
construction and would provide stabilization against bank collapse.

Sewer Branch 1

0+25 to 0+75: Stream crossing S3, CEI Figure 3 (2 of 7) and MESCO Plan Sheet C-8. The
stream would be crossed near perpendicular to flow, requiring 33 lf. of temporary impact. A
cofferdam and pump around and bridge mat would be used at this crossing to avoid impacts to
the stream and its banks.

Sewer Branch 2A

1+25 to 11+50 The construction easement, shown on MESCO Plan Sheet C-9, would be within
10-feet of the existing top of bank along multiple stretches of this alignment. Project designers
have shifted the alignment away from the stream as far as possible. Constraints being balanced
with stream avoidance include homes on both sides of the stream, existing septic fields, and the
need to enable connections from the opposite side of the creek. There is no flexibility to avoid
these encroachments. Project designers are requiring contractors to perform work in this area
during dry periods with no rain in the immediate forecast. Trench boxes would be used during
construction and would provide stabilization against bank collapse.

13+50 to 14+60 and 16+25 to 16+75: The construction easement, shown on MESCO Plan Sheet
C-10, would be within 10-feet of the existing top of bank. These are segments of the same
alignment discussed above and are subject to the same constraints. Project designers are
requiring contractors to perform work in this area during dry periods with no rain in the
immediate forecast. Trench boxes would be used during construction and would provide
stabilization against bank collapse.

19+00: An aerial sewer crossing of Stream S9 (CEI Figure 3 (6 of 7) and MESCO Plan Sheet C -
10) would be installed on piers with no impact to jurisdictional resources. This crossing would be
constructed at a less than perpendicular angle due to property and tie-in constraints. However, no
impact to the stream would result.

Sewer Branch 4B

4+90 to 12+00 The construction easement would be within 10-feet of the existing top of bank
along multiple stretches of this alignment depicted on MESCO Plan Sheet C-17. This area was
previously called out with 176 linear feet of stream (S11) within the construction corridor.
However, because no impact to the stream would result this length is no longer provided on the

North Wilkesboro Sewer Improvements Page 6 of 7
May 23, 2018

impact table. Project designers have shifted the alignment away from the stream as far as
possible. Constraints being balanced with stream avoidance include homes on both sides of the

stream, steep slopes, existing septic fields, and the need to enable connections from the opposite
side of the creek. There is no flexibility to avoid these encroachments. Project designers are
requiring contractors to perform work in this area during dry periods with no rain in the
immediate forecast. Trench boxes would be used during construction and would provide
stabilization against bank collapse.

8+75 to 10+00 Wetland Impact W12 (CEI Figure 3 (7 of 7) and MESCO Plan Sheet C-10). As
mentioned in the paragraph above, this crossing is unavoidable due to numerous constraints
associated with densely distributed residential facilities. This would result in 0.02 ac of
temporary impact and <0.01 ac of permanent impact. An anti-seep collar is provided at the
downstream edge of this feature.

13+00: Stream crossing S12 (CEI Figure 3 (7 of 7) and inset on MESCO Plan Sheet 18). Due to
housing tie-ins, and slope constraints, the corridor crosses stream SI in this area. The previous
alignment included a non-perpendicular crossing intended to avoid septic fields in an adjacent
yard. However, a manhole was able to be relocated to improve the angle of this crossing to near -
perpendicular. The temporary impact at this stream crossing would total 67 lf. This is the upper
reach of a weak intermittent stream that usually does not flow. The crossing would be installed
during dry conditions with no rain in the immediate forecast, and st raw wattles would be
employed to protect downstream reaches of this feature from sedimentation.

Sediment and erosion control measures would be implemented according to NC requirements,
and approved by NCDEQ prior to implementation. Jurisdictional areas adjacent to construction
areas would be clearly marked with protection fencing or other similar method to avoid
inadvertent encroachment. Copies of permits and impact areas would be provided to the prime
contractor and all subcontractors working in or near jurisdictional areas. Land clearing would
take place along with installation of erosion control devices. Construction would be
accomplished using typical equipment including excavators, backhoes, and dump trucks.
Additional equipment may be used as required.

This project would require minimal tree clearing in a county listed by the USFWS as containing
northern long-eared bats (NLEB). We understand that, pursuant to NWP 12 General Permit
Condition 32.(d)(3), the USACE will immediately share a copy of this ap plication with USFWS
to request comments and inform an NLEB effect determination for this project. A Tier 1 search
of the NC Natural Heritage Data Explorer found no records of federally protected species on or
near the project. Their report is attached.

RE: North Wilkesboro Sewer
Dear Christopher Hopper:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
A query of the NCNHP database, based on the project area mapped with your request, indicates that there are
no records for rare species, important natural communities, natural areas, or conservation/managed areas
within the proposed project boundary. Please note that although there may be no documentation of natural
heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have
been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists.
In the event that rare species are found within the project area, please contact the NCNHP so that we may
update our records.
The attached ‘Potential Occurrences’ table summarizes rare species and natural communities that have been
documented within a one-mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists and is
included for reference. Tables of natural areas and conservation/managed area within a one-mile radius of the
project area, if any, are also included in this report.
Please note that natural heritage element data are maintained for the purposes of conservation planning, project
review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions.
Information provided by the NCNHP database may not be published without prior written notification to the
NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP
data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature
Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement,
or Federally-listed species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance, please
contact Rodney A. Butler at [e-mail] or 919.707.8603.
Sincerely,
NC Natural Heritage Program
