Page 6 of 14

Name of nearest receiving body of water: The project is located on a first order intermittent
stream approximately 1000 feet south of its junction with an unnamed tributary to Mine
Creek. Mine Creek flows into Shelley Lake approximately a mile and a half southeast of the
site.
8. River Basin: Neuse River Basin
(Note -this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The general land use is single-family residential in the
developed North Haven Subdivision off of Six Forks Road north of Lynn Road and south of
Sawmill Road. Six Forks Road is a major north-south thoroughfare that be ins just north of
downtown Raleigh and continues north past Falls Lake in northern Wake County
Celebration at Six Forks is the closest commercial shopping center to the site at
approximately two-thirds of a mile north of the subdivision The project begins
approximately 30 feet south (upstream of the yard inlet behind the residence at 304
Westbrook Drive, on the property of 6620 Graymont Place. An existing 24 inch RCP pipe in
the existing channel bed is the entrance to the wipe system This pipe entrance extends
approximately 20 feet south of the yard inlet. The wiped system extends a total of 365 linear
feet through the side yards of 304, 305, and 309 Westbrook Drive. This pipe is in a 40-foot
wide drain and utility easement that also includes an 8" sanitary sewer line The existing
yard inlet is open on all four sides but the entrances are partly blocked by debris• resulting in
the inlets inability to handle all the storm water that flows to it. From the yard inlet storm
water travels through a 24" RCP north to Westbrook Drive (approximately 148 feet
continues north under Westbrook Drive (approximately 40 feet) and then travels another
approximately 148 feet until the 24" RCP discharges into a channel approximately 1 000 feet
south of the unnamed tributary that flows into Mine Creek. Storm water entering the channel
will flow north into the unnamed tributary, which flows into Mine Creek and eventually the
Neuse River. The sanitary sewer line runs roughly parallel to the 24" RCP from the upstream
be~innin~ of the project until the middle of Westbrook Drive where it discharges into an
east-west running sewer line under Westbrook Drive. An 8" water line also runs east-west
under Westbrook Drive. A natural gas line extends from the back of the house at 304
Westbrook Drive and runs roughlyparallel to the sewer line and 24" RCP all the way under
Westbrook Drive and to the west side of the house at 309 Westbrook Drive A natural gas
line runs in an east-west direction in the vicinity of the curb inlet on the north side of
Westbrook Drive and a cable television line runs east-west in the vicinity of the curb inlet on
the south side of Westbrook Drive. An under round power line runs east-west under the
sidewalk on the north side of Westbrook Drive.
10. Describe the overall project in detail, including the type of equipment to be used: The
project will consist of existing storm drainage wipe system retrofits to upgrade an undersized
system that is currently causing structural flooding to nearby residences Project
improvements will begin at the existing 24" RCP pipe approximately 20 feet south of the
yard inlet at 304 Westbrook Drive. The pipe will be removed and the yard inlet will be
Page 7 of 14

replaced with a new yard inlet that will have a large opening at the channel invert and three
additional openings at a higher elevation to allow overland flow to enter the piped s stem
Berms will be built on the west, north, and east sides of the inlet to prevent storm water from
passim by the yard inlet and flowing overland during flood events to the street. The existing
24" RCP from the yard inlet to the street inlets will be replaced with a 36" RCP to handle
additional storm water capacity. The pipe will be replaced with the same length as the
existing approximately 151 feet long. The curb inlets on both the north and south sides of
Westbrook Drive will be replaced as well as two new inlets added that will connect a
proposed 30 inch parallel pipe system south east of the existing 24 inch line The existing
24" RCP connecting the existing catch basins on Westbrook Drive will be replaced with a
30" RCP. Due to existing utilities in the roadway two 30 inch pipes were required to be used
for their shallow depth and total stormwater capacity A portion of the existing sanitary
sewer line in Westbrook Drive will be required to be replaced due to the new storm drainage
construction. Anew 41-foot long 8" DIP sewer line will replace the existing sewer line
under Westbrook Drive spanning the crossing and a new sanitary sewer manhole will be set
The existing 24" RCP from the north side of Westbrook Drive to the outlet into the channel
will remain and an additional 36" RCP will be installed approximately 3 feet south and
parallel to the existing RCP will be installed. Both pipes will dischar e through a new
endwall and the outlet will be protected from erosion with Class II Rip Rap for
approximately 401inear feet. Additional excavation of approximately 701inear feet of excess
sediment will also be done to provide positive drainage and stabilize the banks downstream
of the endwall. The equipment to be used for this project will be dump trucks for hauling a
track hoe for pipe installation and excavation an front end loader pavement saws and soil
compaction equipment.
11. Explain the purpose of the proposed work: The purpose of the work is to upgrade the storm
water drainage system to contain the 10 year storm event The pipe system is currently
undersized and the yards, roadways and structures adjacent to the existin~system currently
are experiencing flooding.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
Provide a written description of the proposed impacts: Approximately 301inear feet of
the channel will be restored in the backyard of 6620 Graymont Place by the removal of an
existing 24 inch pipe and the reopening of the natural channel into the yard inlet.
Approximately 70 linear feet of the channel will be impacted at the bottom of the project by
the stabilization of the channel with Class II Rip Rap and the excavation to improve drainage
and bank stability.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
Page 10 of 14

8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A

local stormwater requirement, etc.): N/A
Current land use in the vicinity of the pond: N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The proposed improvements
are necessary to the existing system to prevent future flooding of structures and streets The
existing system is currently causing flooding because the current storm water pipe system is
under-capacity. The proposed stormwater system improvements will upgrade the system to a 10
year storm event capacityproject is improvin the system at the upstream entrance with the
removal of approximately 20 feet of pipe and reopening the channel. The down stream entrance
into the existing channel will be improved with the removal of excess soil in the channel and
stabilization of the bed and banks with rip rap and biodegradable fabric liner. The channel at
where the 24 and 36 inch pipes discharge receives the highest velocity flows from the culverts
and requires this stabilization to prevent future erosion.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
