Subject: Proposed Neuse River Greenway in Johnston County, TIP No. EB-4993
DWQ Project # 20110175
Dear Dr. Thorpe:
The NC Division of Water Quality has reviewed your submittal for a 401 Water Quality Certification and
Neuse Buffer Rules Authorization for the aforementioned project. Review of your application revealed it
lacking necessary information required for making an informed permit decision. The permit application
was deficient in the following areas:
1. The amount of Neuse Riparian Buffer impacts proposed in the application is 102,227 square feet of
Zone 1 and 154,986 square feet of Zone 2. While the Neuse Buffer Rules Table of Uses indicates that
greenway impacts are "Allowable", they are still subject to review for avoidance and minimization. For a
greenway that is 3.5 miles in length, the amount of buffer impact seems excessive. DWQ understands
the need to locate the greenway along the Neuse River, but would prefer the path be pushed further back
away from the banks. In addition, DWQ has indicated in Buffer Clarification Memo 2009-004 dated
October 26, 2009 (attached) that trails should be outside of Zone 1 to protect streambank stability. If an
applicant must encroach on Zone 1, specific written justification and documentation should be included in
the application.
2. The amount of permanent stream impacts proposed in the application is 409 linear feet, divided among
nine stream crossings. A standard paved greenway width is 10 feet of asphalt plus 2 feet of grass along
each side. DOT proposes piped stream crossings ranging from 3-4 times as wide. Please clarify the need
for such long culverts on this greenway at these numerous crossings.
Therefore, pursuant to 15A NCAC 2H .0507(a)(5), we will have to place the permit application on hold
until we are supplied the necessary information. You have 21 days to respond in writing with the
requested information or notification to this office that the information is forthcoming. If, at the end of
the 21 days, this office has not received this information in writing, we will assume you are withdrawing
your application and it will be returned. Furthermore, until the information is received by the NC
Division of Water Quality, we request (by copy of this letter) that the US Army Corps of Engineers place
the permit application on hold.

Subject: NCDOT Response to NC Division of Water Quality (NCDWQ) Letter, EB-4993
As you are aware, the NC Department of Transportation (NCDOT) submitted a permit
application on February 22, 2011 for TIP Project No. EB-4993 to NCDWQ. This letter
addresses each item in NCDWQ's February 24, 2011 On Hold Letter regarding the proposed
construction of the Neuse River Greenway from the Wake/Johnston County Line to Sam's
Branch Creek in Johnston County. Each question from the original letter is presented below in
italics, with NCDOT's response immediately following. A copy of NCDWQ's letter is also
provided for your convenience.
1. The amount of Neuse Riparian Buffer impacts proposed in the application is 102,227 square
feet of Zone 1 and 154,986 square feet of Zone 2. While the Neuse Buffer Rules Table of Uses
indicates that greenway impacts are "Allowable ", they are still subject to review for avoidance
and minimization. For a greenway that is 3.5 miles in length, the amount of buffer impact seems
excessive. DWQ understands the need to locate the greenway along the Neuse River, but would
prefer the path be. pushed further back away from the banks. In addition, DWQ has indicated in
Buffer Clarification Memo 2009-004 dated October 26, 2009 (attached) that trails should be
outside of Zone 1 to protect streambank stability. If an applicant must encroach on Zone 1,
specific written justification and documentation should be included in the application.
NCDOT and the Trail Designer, Stewart Engineering, have revised the proposed impacts to
reflect what is actually needed for construction. The previous submission with 102,227 square
feet of Zone 1 impacts and 154,986 square feet of Zone 2 impacts included buffer impacts out to
temporary construction easements, per NCDOT protocol. This revision provides a significant
reduction as shown below:

• Original Impacts as previously submitted
o Zone 1 102,227 sq ft 2.34 ac
o Zone 2 154,986 sq ft 3.5 ac
• Impacts as Revised
o Zone 1 81,891 sq ft 1.88 ac ( 20% reduction)
o Zone 2 140,073 sq ft 3.22 ac (10% reduction)
Additionally', the'Town of.Clayton owns and maintains a sewer easement along the first half of
this project (NCDWQ permitno. W00018329). There is a 25 foot- 40 foot wide cleared area
through the,woods that is associated with this easement. Our design attempts to use this
easement and existing cleared area to the greatest extent possible, while still providing for the
safe use of the trail. This design does require adjustments in the alignment to avoid manholes
and to cross jurisdictional features in the best manner. Below is the amount of Buffer Impacts
created by the need to be within the easement and cleared area, or to tie to the easement and
cleared area:
• Zone 1 48,543 sq ft 1.11 ac 59% of total Zone 1 impacts
• Zone 2 99,723 sq ft 2.29 ac 71% of total Zone 2 impacts
Photos and aerials of the cleared sewer easement and the Final Engineering Certification
Acknowledgement for the Town's sewer line are attached.
Following is the justification for the remaining buffer zone 1 impacts, by site:
Site 1 - The proposed trail is within the existing cleared area of the sewer easement as much as
possible, except to avoid.the_existing_man boles.
Site 1B -The proposed crosine of the Neuse River creates this impact. It is necessary to be
within the Buffer Zone 1 to allow for this crossing. The trail is either a bridge,
boardwalk, or within the existing sewer easement for Buffer Zone 1 at this site. This
minimizes the final footprint of the trail to 10'. Additionally, this crossing location was
chosen so that the trail wouldn't impact jurisdictional tributaries of the Neuse just
upstream (western side) and downstream (eastern side). The impact shown allows for a
large crane to be used to set the proposed bridge in place. There is also a Buffer Zone 1
impact north of the Neuse River crossing that is created because the trail is designed to
run within the existing cleared area of the sewer easement, which happens to. partially
be within that Buffer Zone 1.
Site 2 - The Buffer Zone I impact at this site is associated with the tributary of the Neuse that
the trail is crossing, not the Neuse River. This crossing is using a pipe, so the Buffer
Impact is shown. This tributary also jogs to the north after our proposed crossing and
runs parallel to the trail for about 175'. This extends the buffer impact because the trail
is designed to run within the existing cleared area of the sewer easement, except to
avoid the existing manholes.
Site 3 - The Buffer Zone 1 impact at this site is created because the trail shifts towards the river
to avoid a sewer manhole. It is not feasible to shift away from the river because there is
a large hill at this location.
Site 4 - The Buffer Zone 1 impact at this site is created by a cross pipe. The trail is designed
within the existing cleared area of the sewer easement, except to avoid the existing
manholes. At this location, the trail crosses an existing draw and a pipe is necessary to
drain the area on the right side of the trail. Site 4 also includes the crossing of a
tributary (LI Sta. 93+25) of the Neuse River and impacts Buffer Zone 1 of this

tributary. This crossing uses a pipe, so the impact is shown. A second crossing of a
tributary (C 1 Sta. 96+75) of the Neuse creates the last Buffer Zone 1 impact at Site 4.
The trail is shifted slightly towards the river because the tributary turns north just after
the proposed crossing and runs parallel to the trail for approximately 500'.
Site 5 - The Buffer Zone 1 impact at this site is created by the crossing of Marks Creek. The
amount of impact shown allows for a large crane to be used to set the proposed bridge
in place.
Site 6 - The Buffer Zone 1 impact at this site is an impact to the buffer zone of a tributary of the
Neuse River. The trail is crossing this tributary using a cross pipe which'creates the
buffer impact.
Site 7 - The Buffer Zone 1 impact at this site is an impact to the buffer zone of a tributary of the
Neuse River. The trail is crossing this tributary using a cross pipe which creates the
buffer impact.
Site 8 - The Buffer Zone 1 impact at this site is an impact to the buffer zone of the Neuse River
and a jurisdictional tri utary of the Neuse. The trail is crossing the jurisdictional
tributary using a pipe. The tributary jogs to the west after the crossing and runs parallel
to the trail for approximately 250'. The trail would impact this tributary more
significantly than currently proposed if the trail was shifted away from the Neuse buffer
zone.
Site 10 - The Buffer Zone 1 impact at this site is created by the need to tie the end of EB-4993 to
a proposed greenway constructed by others. This proposed greenway constructed by .
others includes a stream crossing close to the end of EB-4993 and that crossing
necessitates the trail to be partially within Buffer Zone 1. Additionally, this site is
located on the side of a steep hill, and the trail is proposed in the flattest part of this hill.
2. The amount of permanent stream impacts proposed in the application is 4091inear feet,
divided among nine stream crossings. A standard paved greenway width is 10 feet of asphalt
plus 2 feet of grass along each side. DOT proposes piped stream crossings ranging from 3-4
times as wide. Please clam the need for such long culverts on this greenway at these numerous
crossings. '
During the design phase of this project, boardwalks spanning many of the smaller stream
crossings were considered. However, it was determined that maintenance of the boardwalk by-
the Town of Clayton would be impractical, both from a cost standpoint and the fact that the trail
has limited access. In addition, future maintenance of isolated portions of the trail itself would
be in jeopardy, as pavers and surfacing equipment could not travel over the boardwalk crossings.
Therefore, piping these crossings was chosen as a more viable option. To that end, NCDOT and
the trail designer reviewed the proposed stream impacts in detail. It was determined that at two
crossings, proposed rip rap stabilization above the ordinary high water mark had been included in
the impact totals. These impacts were removed from the summary and the total stream impact
wasreduced to 394 linear feet.
The total stream impact of 409 linear feet from the previous submission is also a little
misleading. The proposed trail is 10' wide asphalt. However, AASHTO requires a 2' wide
shoulder on either side. Additionally, if the side slope is steep enough, AASHTO recommends a
4' wide shoulder with a railing (3' from edge of trail to railing, 1' behind railing). In an effort to
reduce the total length of stream impact the trail designer has used steep side slimes with railing_
at the jurisdictional stream crossings. This means the trail cross-section is actually 18' wide at
these locations. Additionally, the jurisdictional streams in the project typically have relatively
steep banks. If the jurisdictional stream has 6' banks, which is very common in this area, the
stream impact is increased form the 16' of the trail cross-section by the total height times 2 (each
side of the trail) and times 2 again (2:1 max fill slope). At the 6' high stream,bank, this works
out to be:
6' high stream bank * 2 for each side of the trail * 2 for the max fill slope = 24'
The trail cross-section of 18' is then added to this 24' for the total stream impact at one location
of 42'. This length of impact only gets worse if the crossing is skewed.
This can more easily be depicted by the diagram below:
ELEV. = 20.00
ELEV.= 10.00
ELEV. = 0
Additionally, an error was found in the buffer impact summary submitted with the original
application. In the original, the zone 2 impacts for Site 10 were shown as 1,697 sq ft.; however,
they should have been shown as 2,773 sq. ft. This error has been corrected in the revised buffer
impact summary attached herein.
NCDOT hereby requests that NCDWQ remove the permit application from hold status to allow
for processing to continue. A copy of this letter will be posted on the NCDOT website at:

3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
Project runs parallel to the Neuse River. The trail alignment follows an existing sewer easement south of the Riverwood
Subdivision and runs through forest (about 1.7 miles) north of Riverwood Subdivision. The land use along the project
corridor is predominantly residential.
3b. List the total estimated acreage of all existing wetlands on the property:
1.3 AC delineated per the attached NRTR
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
5,974 LF of Perennial Streams, 1,502 LF of Intermittent Streams - delineated per NRTR and supplemented by ESI
3d. Explain the purpose of the proposed project:
EB-4993 is a greenway project that will connect to the future Neuse River Trail at the Wake/Johnston County. line to the
west and continues along the Neuse River to connect to the Sam's Branch Greenway trail (under construction). In
addition to acting as a link in the Mountains-to-Sea Trail, locally the trail will conned recreational and residential nodes
providing an alternative mode of transportation and increasing recreational opportunities. The major areas being
connected with this trail are the Riverwood Subdivision and the Town of Clayton.
3e. Describe the overall project in detail, including the type of equipment to be used:
The project involves constructing a 10' paved greenway trail from the Sam's Branch Greenway (under construction) to the
Wake/Johnston county line. The proposed greenway will also connect to an existing greenway in the Riverwood Subdivision.
The project includes two pedestrian bridges, one over the Neuse River and the other over Marks Creek.
The contractor will determine the equipment used on the project. However, given the nature of the project there are limited
requirements for additional clearing. Trail contractors generally use small paving machines and earth moving equipment
which have lower impacts to the project area than traditional highway construction equipment. Multiple construction entrances
have been identified to minimize trip distances of equipment. Nationwide Permit 14 General Conditions will be included in
construction documents to direct contractor operations in and around wetlands.

6i. Comments: Greenway Trails are an allowable use within buffer zones. The rip rap encroaching into the Buffer Zones 1 and
2 are NCDOT specked culvert velocity dissipator pads for the drainage culverts beneath the proposed Greenway Trail.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
I a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The horizontal alignment adjusts accordingly to avoid or minimize impacts as much as possible. The trail itself
matches existing grade as to minimize the amount of cut and fill, therefore avoiding or minimizing impacts. Double
headwalls have been used at culvert locations to further reduce impacts.
I b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The contractor shall be responsible for minimizing the impacts through construction techniques. The bid specification will call
for hand clearing where possible, use of construction mats in sensitive areas, small paving machines and generally low impact
machines to be used on the project insensitive areas. Multiple construction entrances have been provided to minimize trip
distances of heavy equipment. Nationwide 23 General Conditions will be included in construction specifications.
