inches, and 1-foot for culverts > 48 inches).
Version 1.4
January 9, 2009
Wetland Impacts:
Precise grading and final elevation contours must be provided. Existing
vegetation and any clearing must be specified.
<?-- All subsurface utility lines must indicate the location of anti-seep collars.
Construction detail for anti-seep collars must be provided.
? Roadway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
?- Plans should show that the hydrology of remaining wetlands on the site will be
maintained.
Stream Impacts:
Stream impacts must be clearly shown on the plans. The centerline as well as
the banks of the stream must be surveyed or located by GPS for the portion of
the stream to be impacted.
The inlet and the outlet of all culverts should be aligned with the stream as
much as possible. Inlet and outlet elevations and streambed elevations should
be indicated. Any inlet or outlet protection must be shown and enumerated on
the impact map(s).
-8-- For bottomless culverts or other spans, a vertical cross section should be
provided that shows the minimum distance from each span to each stream bank,
the stream cross section, the height of the span above the stream and the
minimum distance from the edge of each footer to each stream bank.
Additionally, please provide a signed and sealed geotechnical report of
subsurface soils at the proposed bottomless culvert location. The report must
comply with the Division of Highways - Guidelines for Drainage Studies and
Hydraulic Design, prepared by A.L. Hankins, Jr., State Hydraulics Engineer -
1999.
Multiple culverts or sectioned box culverts typically require the use of sills, off-
setting or other means to match the cross section of the existing stream (in order
to maintain stream stability and provide aquatic life passage). A vertical cross
section of the culverts should be shown overlain with the up and downstream
stream cross section including the stream flood-prone area.
?- Impacts associated with dam construction must indicate and enumerate all fill
associated with the dam footprint, spillway and any bank stream bank
stabilization. The length of stream impounded must also be indicated and
enumerated.

Re: Neuse Buffer Authorization
Highland Creek - Sewer Line
Rolesville, North Carolina
CTX-06070
Dear Mr. McMillan:
On behalf of Pulte Homes (formerly Centex Homes), we are applying for a
Neuse River Riparian Buffer Authorization for impacts to Zone 1 and Zone 2
of an unnamed tributary to the Neuse River, associated with construction of a
section of sanitary sewer line to service the Highland Creek subdivision. The
proposed sewer line is located on the west side NC Hwy 401 (Louisburg
Road), just north of the intersection of NC Hwy 401 and Lowell Ridge Road,
south of Rolesville, Wake County, NC.

WETLAND/STREAM MAPPING: An Army Corps of Engineers field
confirmation for the sewer line study area was conducted on August 7, 2007.
A survey plat was prepared by MSS Land consultants dated August 8, 2007
and submitted to the USACE. The original DWQ Neuse River Buffer
determination was issued January 1, 2005, and another determination letter for
the sewer alignment was issued on July 25, 2007 (NBRRO# 07-140). The
project area contains a total of 0.06 acres (2,780 square feet) of wetlands
within the sanitary sewer study area and field confirmed by the USACE on
August 7, 2007. Approximately 1,450 linear feet of streams were delineated
within the sanitary sewer study area and field confirmed by the USACE and
DWQ.

Highland Creek Sewer

PROJECT LOCATION/HABITAT: The proposed sanitary sewer line to
service the Highland Creek subdivision is located on the west side of NC Hwy
401 (Louisburg Road), just north of the intersection of NC Hwy 401 and
Lowell Ridge Road, south of Rolesville, Wake County, NC. The sewer line
will tie into an existing on-site sewer, run parallel to the Neuse Buffer and
cross an unnamed tributary to the Neuse River, just north of NC Hwy 401
(Figure 3 / Erosion Control Plan Sheet). This unnamed tributary is depicted
on the USGS quad (Figure 1) and Wake County Soils Survey (Figure 2),
therefore it is subject to the Neuse River Riparian Buffer Rules. This aerial
sewer crossing will tie into existing previously permitted sewer to the north
and south of the proposed impact area.
The riparian buffer has been timbered over the past twenty years and is
forested with riparian canopies of Red Maple, Tulip Poplar, Sweet Gum,
Ironwood and a few Oaks species, with an understory Chinese Privet,
Baccharis, and fescue grasses. Land use within the vicinity of the project is
multi-family and single-family residential, light commercial, and natural
forested areas to the north and south of the project area. Louisburg Road on
the southern boundary of the project is currently being widened to four lanes
to accommodate an increase in traffic in this vicinity.
PROPOSED PROJECTAMPACTS: A sanitary sewer line is proposed to
service the southwestern sections of the Highland Creek Subdivision (Phases
2 & 4). Highland Creek Subdivision (Phases 2 & 4) is currently under
construction and was issued a 401 Water Quality Certification and
Authorization Certificate per the Neuse River Buffer Protection Rules on
August 20, 2007 (DWQ Project # EXP 05-1882v5). In addition, approval of
the Stormwater Management Plan for Highland Creek Subdivision (Phases 2
& 4) was issued on July 2, 2007 (DWQ Project # EXP 05-1882v4).
Originally the sanitary sewer line servicing Phases 2 and 4 was to run parallel,
from an existing sewer line, on the west side of the tributary and Neuse
Buffer, and cross Louisburg Road (SR 401) to the south. It has been
determined that the original location was not feasible due to topographic
constraints and the property owner was not willing to allow for adjustment on
the west side of the tributary (Figure 3). Therefore, we are requesting to
locate the sewer line on, the east side of the tributary, tying into an existing
sewer line, running parallel but outside of the Neuse Buffer, with a proposed
aerial crossing which would run parallel to Louisburg Road, then to the south.
It should be noted this area is already cleared, due to the current widening
project of Louisburg Road to a four lane, and is within NCDOT's clearing
limits. The sanitary sewer line will terminate at an existing sanitary sewer

easement located south of Louisburg Road. We are requesting Riparian
Buffer Approval for impacts associated with Neuse River Buffers.
The proposed sanitary sewer will be designed to cross the unnamed tributary to
the Neuse River at a near perpendicular angle. The proposed sewer line will
consist of an 8 inch ductile iron pipe located within a 20 foot permanently
maintained maintenance easement. Most of the sewer line has been installed
using traditional methods of trench and backfill up to this point, however, at the
proposed stream crossing the trenching will stop just inside of the Neuse Buffer
on both sides of the tributary and the sewer line will span the stream in this
location, and be trenched into the Neuse Buffer on the other side of the stream.
The total Neuse Buffer impacts are 1,589 square feet of Zone 1 and 1,406
square feet of Zone 2, and fall within the clearing limits of the current NC Hwy
401 (Louisburg Road) widening project. It should be noted that this area is
already cleared and stabilized due to the current construction of NC Hwy. 401,
but will remain a permanently maintained sewer easement through this area
(Figure 3 / Pics 1-3).

AVOIDANCE and MINIMIZATION: Most of the sewer line has been
installed using traditional methods of trench and backfill up to this point,
however, at the proposed stream crossing the trenching will stop just inside of
the Neuse Buffer on both sides of the tributary and the sewer line will span the
stream in this location, and be trenched into the Neuse Buffer on the other side
of the stream; thereby avoiding direct stream impacts in this location.
To minimize impacts, the sanitary sewer has been aligned near perpendicular as
it crosses the unnamed tributary, reducing stream buffer impacts in this
location. A further reduction in impacts has been achieved by locating the
proposed sewer line within the will be within the clearing limits of the current
NC Hwy 401 (Louisburg Road) widening project. The permanent maintained

easement has been reduced to 20-feet in width, the minimum width allowed by
the City of Raleigh. In addition, although it is an allowable use, all other
portions of this sanitary sewer section that run parallel to the tributary have been
located outside of the Neuse River Buffer, further avoiding impacts (Figure 3).
DIFFUSE FLOW: The Highland Creek Subdivision (Phases 2 and 4) has
received an approval of storm water management plan from NCDWQ (Project
# EXP 05-1882v4; dated July 2, 2007). Construction of the proposed sanitary
sewer will add an insignificant amount of impervious surface associated with
the man-hole covers. Therefore, treatment for the sanitary sewer line is not
proposed. Erosion control practices will be implemented to help mitigate
impacts to water quality, during construction. (Erosion Control Plans
Enclosed). There are no erosive flows through the Neuse Buffer expected
during and after construction.
MITIGATION: All buffer impacts are deemed "Allowable''' under the Neuse
River Riparian Buffer Rules - Table of Uses, therefore no mitigation is
proposed.
Consideration of this project is greatly appreciated. If you should have any
questions or require additional information, please do not hesitate to contact
me at [phone].

3. Project Description
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:
The proposed sanitary sewer line to service the Highland Creek subdivision is located on the west side NC Hwy
401 (Louisburg Road), just north of the intersection of NC Hwy 401 and Lowell Ridge Road, south of Rolesville,
Wake County, NC. The sewer line will tie into an existing on-site sewer, run parallel and cross an unnamed
tributary to the Neuse River. This unnamed tributary is depicted on the USGS quad (Figure 1) and Wake County
Soils Survey (Figure 2), therefore it is subject to the Neuse River Riparian Buffer Rules. This aerial sewer crossing
will tie into existing previously permitted sewer to the north and south of the proposed impact area.
The riparian buffer has been timbered over the past twenty years and is forested with riparian canopies of Red
Maple, Tulip Poplar, Sweet Gum, Ironwood and a few Oaks species, with an understory Chinese Privet,
Baccharis, and fescue grasses. Land use within the vicinity of the project is multi-family and single-family
residential, light commercial, and natural forested areas to the north and south of the project area. Louisburg
Road on the southern boundary of the project is currently being widened to four lanes to accommodate an
increase in traffic in this vicinity.
3b. List the total estimated acreage of all existing wetlands on the property:
A total of 0.06 acres (2,780 square feet) of wetlands were delineated within the sanitary sewer study area and field
confirmed by the USACE on August 7, 2007.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Approximately 1,450 linear feet of streams were delineated within the sanitary sewer study area and field confirmed by
the USACE on August 7, 2007.
3d. Explain the purpose of the proposed project:
The purpose of the proposed project is to provide sanitary sewer service to the Highland Creek Subdivision.
C. Stormwater Management and Diffuse Flow Plan (required by DWQ), continued
3e. Describe the overall project in detail, including the type of equipment to be used:
A sanitary sewer line is proposed to service the southwestern sections of the Highland Creek Subdivision (Phases
2 & 4). Highland Creek Subdivision (Phases 2 & 4) is currently under construction and was issued a 401 Water
Quality Certification and Authorization Certificate per the Neuse River Buffer Protection Rules on August 20, 2007
(DWQ Project # EXP 05-1882v5)). In addition, approval of the Stormwater Management Plan for Highland Creek
Subdivision (Phases 2 & 4) was issued on July 2, 2007 (DWQ Project # EXP 05-1882v4). Originally the sanitary
sewer line servicing Phases 2 and 4 was to run parallel, from an existing sewer line, on the west side of the
tributary and Neuse Buffer, and cross Louisburg Road (SR 401) to the south. It has been determined that the
original location was not feasible due to topographic constraints and the property owner was not willing to allow for
adjustment on the west side of the tributary (Figure 3). Therefore, we are requesting to locate the sewer line on the
east side of the tributary, tying into an existing sewer line, running parallel but outside of the Neuse Buffer, with a
proposed aerial crossing which would run parallel to Louisburg Road, then to the south. It should be noted this
area is already cleared, due to the current widening project of Louisburg Road to a four lane, and is within
NCDOT's clearing limits. The sanitary sewer line will terminate at an existing sanitary sewer easement located
south of Louisburg Road. We are requesting Riparian Buffer Approval for impacts associated with Neuse River
Buffers.
The proposed sanitary sewer will be designed to cross the unnamed tributary to the Neuse River at a near
perpendicular angle. The proposed sewer line will consist of an 8 inch ductile iron pipe located within a 20 foot
permanently maintained maintenance easement. Most of the sewer line has been installed using traditional methods
of trench and backfill up to this point, however, at the proposed stream crossing the trenching will stop just inside of the
Neuse Buffer on both sides of the tributary and the sewer line will span the stream in this location, and be trenched
into the Neuse Buffer on the other side of the stream. The total Neuse Buffer irnpacts are 1,589 square feet of Zone 1
and 1,406 square feet of Zone 2, and fall within the clearing limits of the current NC Hwy 401 (Louisburg Road)
widening project. It should be noted that this area is already cleared and stabilized due to the current construction of
NC Hwy. 401, but will remain a permanently maintained sewer easement through this area (Figure 3 / Pics 1-3).

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Most of the sewer line has been installed using traditional methods of trench and backfill up to this point, however, at
the proposed stream crossing the trenching will stop just inside of the Neuse Buffer on both sides of the tributary and
the sewer line will span the stream in this location, and be trenched into the Neuse Buffer on the other side of the
stream; thereby avoiding direct stream impacts in this location.
To minimize impacts, the sanitary sewer has been aligned near perpendicular as it crosses the unnamed tributary, reducing
stream buffer impacts in this location. A further reduction in impacts has been achieved by locating the proposed sewer line
within the will be within the clearing limits of the current NC Hwy 401 (Louisburg Road) widening project. The
permanent maintained easement has been reduced to 20-feet in width, the minimum width allowed by the City of
Raleigh. In addition, although it is an allowable use, all other portions of this sanitary sewer section that run parallel to the
tributary have been located outside of the Neuse River Buffer, further avoiding impacts (Figure 3).
C. Stormwater Management and Diffuse Flow Plan (required by DWQ), continued
1 b . Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
- The temporary construction corridor within the Neuse River Buffer will fall within the permanently maintained 20-
foot easement area through the Neuse Buffer, minimizing impacts from construction.
- Proper sedimentation and erosion control methods will be utilized during all phases of construction and installation
as described in the Erosion Control Plan sheet reviewed and approved by the NC Division of Land Quality and City
of Raleigh. All work will take place during dry conditions and can be facilitated from high, non-jurisdictional, stable
ground adjacent to the Neuse Buffer. The contractor shall install silt fence, inlet protection, sediment traps,
diversion ditches, tree protection, clearing only as necessary to install these devices. All erosion and sediment
control measures will be checked for stability and operation following every runoff producing rainfall , but in no case
less than once every week. Any needed repairs will be made immediately to maintain all measures designed. An
erosion control inspections report is required and will be kept by the owner's representative.
