SUBJECT: Nationwide Permit Application for Burning Tree Drive Drainage
Improvements Project, Town of Chapel Hill, Orange County
Dear Mr. Williams,
The Town of Chapel Hill (Town) proposes to construct drainage improvements to address
stormwater control problems in The Oaks subdivision at Chapel Hill Country Club in
Orange County. The project site is within USGS hydrologic unit 03030002 and is part of the
Little Creek drainage in the Cape Fear River Basin. An unnamed tributary (UT) to Little
Creek occurs in the project area and is identified by NC Division of Water Quality Index
Number 16-41-1-15-(0.5). The location of the project is shown on the attached Figures 1
through 3.
The overall project as proposed will install new stormwater collection system components
which will include new yard basins, catch basins, junction boxes, and concrete pipes along
Burning Tree Drive and Pinehurst Drive. Construction will primarily occur in upland areas;
however, the project includes placement of fill in the UT to Little Creek where it occurs at
Burning Tree Drive and in a manmade stormwater pond that is hydrologically connected to
Little Creek. The Town is requesting these impacts be authorized under the Nationwide
Permit program. It is anticipated that several different permits will apply to the different
types of fill created by this proposed project, as described below.
0 Installation of a rip-rap energy dissipater pad on the UT to Little Creek will create
impacts below an existing 42-inch diameter pipe outlet at Burning Tree Drive. The
stream banks at the pipe outlet have been severely eroded from stormwater scour
such that the pipe is perched above the channel. Approval for dissipater pad impacts
is requested under NWPs 13 and 39 as this work is being completed to prevent
further erosion of the channel which is being used as part of the Town's overall
storm water management facilities in the community.
Channel stabilization would also include installation of a rock cross vane structure
immediately downstream from the dissipater pad. It is requested this work be
authorized by NWP 27 as the rock vane will enhance stream stability and aquatic
habitats by directing flow into the middle of the channel and away from the banks.
Geotextile fabric will be used in the channel under the energy dissipater pad and rock

cross vane. Inspection (monitoring) of the rock vane for five years from date of
construction is proposed to ensure it functions as designed.
Existing dual 24-inch pipes on the UT to Little Creek will be replaced with a new 6-
foot by 3-foot precast concrete box culvert. The current pipes provide a golf cart
path crossing of the stream at the 17`h hole golf course fairway and are undersized
for current stormwater volumes. The Town requests approval under NWP 3 for
maintenance activities to replace the pipes with a box culvert with wing walls and rip-
rap for stabilization at the inlet and outlet side of the culvert.
Stormwater collected in upland areas will be directed through new pipes installed
along Pinehurst Drive and discharged into a man-made pond located adjacent to
Pinehurst Drive; the pond is hydrologically connected through a series of
downstream ponds to Little Creek. The pond is currently used by the golf course for
stormwater retention and turfgrass irrigation. Impacts will be created by
construction of the dual 36-inch pipes with headwall structure to sit below the
normal water surface elevation. The pipe outlet will be submerged as a safety
measure to prevent pedestrians and domestic pets from entering the pipes. Approval
for this work is requested under NWP 12 for utility line activities.
Work completed in the UT to Little Creek and the stormwater pond will be
completed in dry conditions. To accomplish this, approval is requested under NWP
33 for use of a temporary dewatering system using check dams, sand bags, and
diversion pipes.
Temporary impacts will occur to the UT to Little Creek from installation of coir
fiber matting at two floodplain drainways that will be created downstream of the
rock vane. The low berm located along the right top of bank on the UT to Little
Creek will be breached in two places to reconnect adjacent residential yards to the
stream channel and allow overbank flood waters and stormwater detention to drain
back into the UT channel. Coir fiber matting will be installed in the drainways and at
the top of bank on the UT to stabilize disturbed areas and will be anchored with live
stake vegetation.
Please find attached a permit application package which includes a Pre-Construction
Notification form, list of property owners, figures, photographs, permit drawings, half-sized
plan sheets, and a CD with electronic copies of the permit documents. The USACE
Rapanos determination forms were previously submitted for review; however, an electronic
copy of the forms is included on the CD. We anticipate that corresponding Section 401
General Water Quality Certifications will be authorized by the North Carolina Division of
Water Quality through the Express Review program. The Town of Chapel Hill and its
contractors will comply with all conditions of the 404/401 permits.

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 project is located in Orange County, within the Chapel Hill Oaks Subdivision and Chapel Hill Country
Club (see Figures 1 and 2).
Land within the subdivision is developed for large lot single family residences (0.5 to i acre) and an 18-hole golf
course with country club facilities. The topography is relatively flat to moderately sloped within the subdivision.
Residential yards are manicured lawns surrounded by a mature overstory of mixed pine and hardwoods and understory
of horticulture plantings. In naturalized areas the understory is relatively clear due to landscape maintenance activities,
deer browse, and shading effects. The subdivision has an existing underground stormwater collection system, comprised
of curb inlets. catch basins, junction boxes. and concrete pipes, which is maintained by the Town of Chapel Hill. The golf
course has several large, constructed ponds located on the east side of Pinehurst Drive that are used for storm water
storage and to irrigate the golf course turfgrass.
Approximately 1,775 linear feet of an intermittent/perennial stream, an unnamed tributary (LIT) to Little Creek, flows
northeastward through the subdivision and crosses two golf course fairways. The stream flows through small diameter
corrugated plastic pipes on the golf fairways and through a 42-inch diameter reinforced concrete pipe at Burning Tree
Drive. The high stream bank at the Burning Tree Drive pipe outlet shows evidence of severe erosion and scouring at the
pipe outlet has resulted in the pipe perching above the channel. Scour has also occurred where the UT flows through
dual 24-inch corrugated plastic pipes at the 17th fairway golf cart path. A low spoil cast pile exists at the top of banks
downstream of Burning Tree Drive and this low berm prevents stormwater from receding into the creek.
Attached photo log shows existing conditions of these areas. Figure 2 identifies the location where proposed work will
create impacts to the UT to Little Creek and to a stormwater pond located near the Pinehurst Drive and Burning Tree
Drive intersection.
3b. List the total estimated acreage of all existing wetlands on the property:
There are no wetlands within the areas proposed for construction of stormwater control measures.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Over 7.000 linear feet of intermittent and perennial streams are located within the subdivision and golf course.
Approximately 850 linear feet of the intermittent LIT to Little Creek is located between Burning Tree Drive and its
confluence with Little Creek.
3d. Explain the purpose of the proposed project:
The overall project as proposed will
install new stormwater collection yard basins. catch basins. junction boxes, and concrete pipes in upland areas along
Burning Treet Drive and Pinehurst Drive;
redirect stormwater collected from existing components to the new catch basins, junction boxes, and concrete pipes;
install dual 36-inch diameter stormwater pipe outlets to carry stormwater collected by new upland yard inlets into an
existing man-made stormwater pond adjacent to Pinehurst Drive near the Burning Tree Driver intersection.
install a rip-rap energy dissipater pad below the Burning Tree Drive pipe outlet;
install a rock cross vane below the new rip-rap energy dissipater pad;
breach the low berm on the right bank of LIT to Little Creek in two locations to reconnect and improve floodwater
drainage downstream from Burning Tree Drive (breach will be above the ordinary high water mark); and
replace undersized dual 24-inch diameter corrugated plastic pipes at the 17th hole fairway golf cart path with a precast
concrete 6-foot by 3-foot box culvert.
Page 4 of 12
PCN Form - Version 1.3 December 10. 2008 Version
3e. Describe the overall project in detail, including the type of equipment to be used:
Proposed impacts covered by this permit application include the installation of a rip-rap energy dissipator pad on UT to
Little Creek below the Burning Tree Drive pipe outlet; installation of a rock cross vane structure immediately downstream
from the dissipator pad; installation of coir fiber matting at two floodplain drainways created by breaching low berm on UT
to Little Creek; replacing the dual 24-inch plastic pipes at the 17th hole fairway golf cart path; and installing stormwater
pipe outlets in a stormwater retention pond adjacent to Pinehurst Drive. Other stormwater system improvements and
required underground utility relocation work will occur in uplands and will not impact jurisdictional resources.
The rip-rap energy dissipator pad and rock cross vane witl be installed to reduce bank erosion below the perched
Burning Tree Drive pipe outlet. The energy dissipator pad will be approximately 1.7 feet deep.. with the shape conforming
to the natural channel geomorphology to provide a smooth transition from end of apron to natural channel width. A rock
cross vane will be constructed at the end of the dissipator pad to provide stability and to direct water flows into the center
of the channel and away from the banks. Geotextile fabric will be used in the channel under the energy dissipater pad
and rock cross vane. A temporary coffer dam and diversion pipe will be used to divert water flow so work can be
performed in dry conditions. Vegetation will be planted along the disturbed banks to provide stabilization and to anchor
the geotextile fabric.
The low berm located along the right top of bank on the UT to Little Creek, between Burning Tree Drive and the 17th
hole fairway, will be breached in two places downstream from the rock cross vane. The breaches will be made above the
ordinary high water mark and in areas where tree removal will not be required. Two shallow floodplain drainways will be
built in upland areas to reconnect adjacent residential yards to the stream channel and allow overbank flood waters and
stormwater detention to drain back into the UT channel, thereby alleviating stormwater retention in adjacent residential
yards. Coir fiber matting will be installed in the drainways and at the top of bank on the UT to stabilize disturbed areas
and will be anchored with live stake vegetation.
The dual 24-inch diameter corrugated plastic pipes located under the 17th hole fairway paved golf cart path will be
removed and replaced with a precast 6-foot by 3-foot concrete box culvert with head wall and wing walls. The new box
culvert will provide increased capacity to carry storm water flows in the UT to Little Creels channel, thereby alleviating
backwater bank and channel scouring and flooding into residential yards. Temporary cofferdams and diversion pipe will
be used to divert water flow so work can be performed in dry conditions.
Dual 36-inch diameter reinforced concrete pipe outlets with a concrete headwall will be installed to carry stormwater
into the golf course stormwater management pond (P1) located on the east side of Pinehurst Drive. The pipes will be
constructed to sit below the normal open water surface elevation. Temporary sand bags and a water diversion pipe will
be used during construction so work can be performed in dry conditions.
Construction equipment will include a track hoe and front loader, dump trucks for material delivery, hand tools, and
other common construction equipment used in underground utility construction as needed.

6h. Total buffer impacts 11,680 1,039
6i. Comments: Per 15A NCAC 028.0267(9), riparian buffer impacts are allowable. Buffer impacts are for construction of rip-
rap energy dissipater pad and rock cross vane at Burning Tree Drive pipe and are temporary because disturbed areas will be
replanted as shown on Permit Drawing Sheets 11 and 12.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Avoidance measures include retaining the existing Burning Tree Drive 42-inch diameter concrete pipe, retaining existing
channel geomorphology instead of creating a new channel, and not placing existing channel into stormwater pipes.
Minimization measures include breaching the low berm at the top of bank above the ordinary high water mark and installing
drainway in areas where vegetation will not need to be removed.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Where possible.. work will be completed using hand tools. This will avoid damage to the mature vegetation along the stream
banks and will limit the number of trees that must be removed for construction.
