Re: Prestonwood CC Stream Bank Stabilization - Meadows Course Hole #3
NWP 13 PCN Submittal
WR Project #02170231.00
Dear Ms. Higgins,
On behalf of Prestonwood Country Club, Inc., we are requesting a 401 WQC for 192 If of temporary
stream impacts and a Buffer Authorization for 14,468 sf of impacts to Neuse River Riparian Buffers
for the proposed stabilization of the eastern bank of Crabtree Creek adjacent to Hole #3 of the
Meadows Course. Please note that the proposed project does not require a 404 permit as less than
500 If of temporary impacts for stream bank stabilization does not require notification to the
USACE.
The project area is ±0.51 acres in size and is located on the western side of Hole #3 of the Meadows
Course at Prestonwood Country Club in Cary, Wake County (Latitude: 35.803665°N; Longitude: -
78.833349°W). The project is located in the Neuse River basin and the project area is located
adjacent to Crabtree Creek. The Water Quality Classification for Crabtree Creek is C;NSW and the
Stream Index Number is: 27-33-(1). The cataloging unit for the site is 03020201.
Proposed Project
The proposed project consists of the stabilization of the eastern bank of a section of Crabtree Creek
which runs along the western edge of Hole #3 of The Meadows course in the Prestonwood Country
Club. The project area currently consists of regularly mowed turf grass associated with the golf
course. Currently, the stream banks are severely eroding and collapsing, with near vertical stream
banks. The erosion has caused Crabtree Creek to widen, and the existing cart path/walking trail is
about to collapse into the stream. The proposed project would result in stabilization of the stream
banks by grading the eastern slope to a 3:1 grade, and planting the slope with riparian vegetation.
Additionally, the existing cart path/walking trail and tee box would be removed, and constructed
further away from Crabtree Creek. The new tee box would be constructed entirely outside of the
riparian buffer, and the new cart path/walking trail would be constructed entirely within Zone 2 to
avoid impacts to Zone 1.
The grading the slopes of the stream bank will result in the relocation of the eastern "top of bank"
of Crabtree Creek, from which a new Zone 1 and Zone 2 will be established. The spoil resultingfrom
the excavation of the stream bank will be spread throughout the newly established Zone 1 and Zone
2, which is a requirement of the Town of Cary to meet FEMA requirements for a no net change in
219 Station Road, Suite 1011 Wilmington, NC 28405

the floodplain. Please note that the proposed grading shown on the impact maps are 3 -inch
contours, and any slopes resulting from the grading will be a minimum of 10:1 and will not affect
sheet flow through the buffer. The newly established Zone 1 will be planted with riparian
vegetation as documented in the Planting Plan & Detail, which has been provided as an Appendix,
which will improve Zone 1 from the current condition of mowed turf grass. Zone 2 will be replanted
with turf grass, which is consistent with the existing conditions.
Project History_
A site visit was conducted by Jennifer Burdette with NCDWR, where she met with Greg Jennings
of Jennings Environmental to discuss the proposed project.
A pre -application teleconference was conducted with Troy Beasley (WithersRavenel) and
Stephanie Goss (NCDWR) to discuss the proposed project and impacts.
There are no wetlands within the proposed project area.
Proposed Impacts
The proposed impacts consist of 192 If of temporary stream impacts and 14,468 sf of impacts to
Neuse River Riparian Buffers.
Impact 1 will result in 192 If of temporary stream impacts which will occur during excavation of the
stream bank to lay the slopes back to a 3:1 slope. Excavation below the OHWL will be minimized to
the greatest extent possible.
Impact 2 will result in 1,924 sf of permanent impacts to Zone 1 as a result of excavation of the buffer
to establish a 3:1 slope of the eastern bank of Crabtree Creek. Zones 1 and 2 will be established
from the newly created top of bank.
Impact 3 will result 8,247 sf of temporary impacts to Zone 1 as a result of grading within the buffer
to spread the excavated material within the buffer and planting of riparian vegetation within Zone
1 per the Planting Plan & Detail, which has been provided as an Appendix.
Impact 4 will result in 69 sf of permanent Zone 1 impacts and 4,228 sf of permanent Zone 2 impacts
for construction of the new cart path/walking trail to replace the existing cart path/walking trail
that currently runs along the bank of Crabtree Creek.
Avoidance and Minimization
The proposed project consists of stabilization of the eastern bank of Crabtree Creek and re-
establishment of the riparian buffers, and as such, impacts could not be avoided. The proposed
project will result in an overall improvement to both Crabtree Creek and the associated riparian
buffers. Currently, the banks of Crabtree Creek are almost vertical, resulting in significant erosion
and bank failure after rain events. The proposed impacts from laying the bank slope back to a 3:1
slope will improve the water quality of Crabtree Creek by reducing sedimentation due to erosion.

Additionally, the planting of Zone 1 with riparian vegetation will further help to stabilize Crabtree
Creek, and will create a more natural Zone 1 buffer as opposed to the existing condition of mowed
turf grass.
The proposed cart path/walking trail has been relocated from the bank of Crabtree Creek, entirely
within Zone 1, to within Zone 2. Due to the overall cost of the proposed stabilization and buffer
planting activities, the proposed cart path/walking trail could not be relocated outside of Zone 2 as
the additional cost associated with routing it outside of the buffer and west of the new tee box was
cost prohibitive.
Mitigation
The proposed stream impacts are temporary, and therefore stream mitigation is not proposed.
Additionally, all proposed buffer impacts as classified as "Allowable” and therefore buffer
mitigation is not required.
The current request is for 192 If of temporary stream impacts and 14,468 sf of impacts to Neuse
River Riparian Buffers (see the attached maps and PCN for details).
Please feel free to call if you have questions or require additional information.

Explain the purpose of the proposed project:
The purpose of the proposed project is to stabilize a 192 If portion of Crabtree Creek to prevent further erosion of the
stream channel and damage to the golf course.
3e.
Describe the overall project in detail, including the type of equipment to be used:
Currently, the stream banks are severely eroding and collapsing, with near vertical stream banks. The erosion has
caused Crabtree Creek to widen, and the existing cart path/walking trail is about to collapse into the stream. The
proposed project would result in stabilization of the stream banks by grading the eastern slope to a 3:1 grade, and
planting the slope with riparian vegetation. Additionally, the existing cart path/walking trail and tee box would be
removed, and constructed further away from Crabtree Creek. The new tee box would be constructed entirely outside of
the riparian buffer, and the new cart path/walking trail would be constructed entirely within Zone 2 to avoid impacts to
Zone 1.
The grading the slopes of the stream bank will result in the relocation of the eastern "top of bank" of Crabtree Creek, from
which a new Zone 1 and Zone 2 will be established. The spoil resulting from the excavation of the stream bank will be
spread throughout the newly established Zone 1 and Zone 2, which is a requirement of the Town of Cary to meet FEMA
requirements for a no net change in the floodplain. Please note that the proposed grading shown on the impact maps are
3 -inch contours, and any slopes resulting from the grading will be a minimum of 10:1 and will not affect sheet flow through
the buffer. The newly established Zone 1 will be planted with riparian vegetation as documented in the Planting Plan &
Detail, which has been provided as an Appendix, which will improve Zone 1 from the current condition of mowed turf
grass. Zone 2 will be replanted with turf grass, which is consistent with the existing conditions.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed project consists of stabilization of the eastern bank of Crabtree Creek and re-establishment of the riparian
buffers, and as such, impacts could not be avoided. The proposed project will result in an overall improvement to both
Crabtree Creek and the associated riparian buffers. Currently, the banks of Crabtree Creek are almost vertical, resulting in
significant erosion and bank failure after rain events. The proposed impacts from laying the bank slope back to a 3:1 slope will
improve the water quality of Crabtree Creek by reducing sedimentation due to erosion. Additionally, the planting of Zone 1
with riparian vegetation will further help to stabilize Crabtree Creek, and will create a more natural Zone 1 buffer as opposed to
the existing condition of mowed turf grass.
The proposed cart path/walking trail has been relocated from the bank of Crabtree Creek, entirely within Zone 1, to within
Zone 2. Due to the overall cost of the proposed stabilization and buffer planting activities, the proposed cart path/walking trail
could not be relocated outside of Zone 2 as the additional cost associated with routing it outside of the buffer and west of the
new tee box was cost prohibitive.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Disturbance to Crabtree Creek will be minimized by accessing the project area through high ground. Silt fence will be installed
around all disturbed areas.

CONTAINER STOCK I LIVE STAKES
A. STOCK SHALL HAVE BEEN GROWN IN A CONTAINER LONG ENOUGH FOR THE ROOT SYSTEM TO HAVE DEVELOPED SUFFICIENTLY TO HOLD ITS SOIL TOGETHER
ONCE REMOVED FROM THE CONTAINER.
B. CONTAINER PLANTS WILL NEED TO BE WATERED REGULARLY AND PLACED IN SHADY CONDITIONS UNTIL PLANTING OCCURS.
C. CUTTINGS SHOULD BE INSTALLED THE SAME DAY THEY ARE CUT. THE STAKE SHOULD BE ORIENTED WITH THE BUDS POINTED UP, AND THE BOTTOM SHOULD BE
CUT AT AN ANGLE FOR EASY INSERTION INTO THE GROUND.
D. ABOUT FOUR-FIFTHS OF THE LENGTH OF THE STAKE SHOULD BE BELOW GROUND AND ANGLED DOWNSTREAM. AN IRON BAR CAN BE USED TO MAKE A PILOT
HOLE TO PREVENT BARK FROM BEING DAMAGED DURING INSTALLATION.
PLANT LOCATIONS
A. NEW PLANTINGS SHALL BE LOCATED WHERE SHOWN ON PLAN EXCEPT WHERE CHANGES HAVE BEEN MADE BY THE PROJECT ENGINEER ONSITE.
B. NECESSARY ADJUSTMENTS SHALL BE MADE ONLY AFTER APPROVED BY THE OWNER OR PROJECT ENGINEER.

EROSION CONTROL MATTING
NOTES
1. EROSION CONTROL MATTING IS USED TO PROTECT RECENTLY CONSTRUCTED
STREAM BANKS FROM EROSION. THE MATTING WILL REMAIN INTACT WHILE THE BANK
AND RIPARIAN VEGETATION MATURES, PROVIDING CRITICAL BANK PROTECTION.
2. BEFORE INSTALLING COIR FIBER BLANKET, RAKE SOIL LEVEL AND ADD SEED,
FERTILIZER, LIME AND MULCH.
3. 700 GRAM COIR FIBER EROSION CONTROL MATTING SHALL BE PLACED ALONG THE
LENGTH OF THE NEW CHANNEL FROM THE TOE OF SLOPE OUT TO A MINIMUM OF 3 FT
BEYOND THE BANKFULL ELEVATION.
4. SECURE COIR MATTING IN PLACE BY STAKING AND OVERLAPPING AT THE SEEMS WITH
A SHINGLE -TYPE METHOD SUCH THAT THE OVERLAPPING PIECE IS IN THE SAME
DIRECTION AND AS THE STREAM FLOW. ADDITIONAL STAKING SHALL BE APPLIED BY
THE CONTRACTOR AT NO ADDITIONAL COST IF THE MATTING SEPARATES FROM THE
SOIL MORE THAN ONE INCH UNDER A REASONABLE PULL.
