W &R Project #02050400.15
Dear Ms. Higgins,
ENGINEERS PLANNERS I SURVEYORS
Qr=
AUG - i 2013
On behalf of the Town of Cary, we are requesting a 401 WQC & Buffer Authorization for 33 if
of permanent stream impacts and 2,618 sq ft of permanent buffer impacts for construction
of the proposed project. Please note that the Corps of Engineers has authorized the
proposed project under a non - reporting NWP 3 in an email dated July 11, 20'12. A copy of the
Corps email has been provided as an Appendix.
The project is t0.4 acres in size and is located at 103 Rattle Snap Court in Cary, Wake County
(Latitude: 35.79428 °N; Longitude: - 78.850070 °W). The project is located in the Neuse River
basin and onsite waters drain to Turkey Creek. The Water Quality Classification for Turkey
Creek is C; NSW and the Stream Index Number is: 27-3341)• The cataloging unit for the site
is 03020201.
Proposed Project
The proposed project consists of the construction of a grassed Swale and flood storage
basin to alleviate flooding problems within the project area. Currently, a UT to Turkey creek
flows south through the project area and is captured by a 30" pipe which flows into a
stormwater collection system along Rattle Snap Court and ultimately discharges into Turkey
Creek. The 30" culvert is undersized for the volume of stormwater during high flow events
and causes flooding upstream and in the surrounding area. The flooding was such an issue
that the project site was previously a house /yard that flooded so often that Town of Cary
actually purchased the house from the property owner. The project proposes to replace the
30" pipe with a grassed Swale which will discharge into a 48" pipe, which then discharges
1410 Commonwealth Drive I Suite 1011 Wilmington, NC 28403 ( tel: [phone] fax: [phone]
www.withersravenel.com I License No. C -0832

into the stormwater collection system. The grassed swale will essentially create an
additional ±135 if of open channel which is currently contained within the 30" pipe. A flood
storage area will also be constructed within the empty lot adjacent to the grassed Swale to
allow for storage of excess stormwater during storm events. The flood storage area is
necessary to contain excess stormwater during storm events to protect the adjacent
residences from being flooded, which is currently the case. Also as part of the project,
existing rip -rap within the stream at the upstream end of the existing culvert will be replaced
with new rip -rap, and additional rip -rap will be placed outside of the channel to provide
stream bank stabilization in order to prevent erosion during periods of high flow /storm
events.
Proposed Impacts
The replacement of the existing rip -rap will result in 33 if of permanent stream impacts
(Impact #1).
The placement of rip -rap at the northern end of the grassed Swale for stream bank
stabilization will result in 558 sq ft of permanent Zone 1 impacts (Impact #2).
The construction of the flood storage basin for protection of the adjacent houses will result
in 685 sq ft of permanent Zone 1 Impacts and 558 sq ft of permanent Zone 2 impacts
(Impact #3).
Avoidance and Minimization
Due to the nature of the proposed project, impacts to the onsite stream and buffers could
not be avoided. The proposed project is necessary for protection of the existing adjacent
houses. Currently, the adjacent yards become flooded during heavy rain events. The
proposed grass swale and 48" pipe will allow for more efficient conveyance of stormwater,
and the flood storage area will allow excess stormwater runoff to be contained, protecting
the adjacent properties from flooding.
Stream impacts have been minimized to only the replacement of existing rip -rap.
The project has been designed to minimize buffer impacts to primarily impact the mowed
grass buffers, with minimal impacts to the native vegetation buffers along the northern
property line.

Mitigation
Because the proposed permanent stream impacts at Impact #i consist of the replacement
of existing rip -rap and are less than 1501f, no stream mitigation is proposed.
Buffer impacts at Impact #2 consist of stream bank stabilization, which is an "Allowable"
activity, buffer mitigation is not proposed for Impact #2. Also, buffer impacts at Impact #3
will occur from a flood storage area, which is classified as a stormwater management pond
The current request is for 331f of permanent stream impacts and 2,618 sq ft of permanent
buffer impacts (see the attached maps and PCN for details).
Please feel free to call if you have questions or require additional information.

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 project site was previously a residence with a house and maintained lawn. The house has been torn down, and the
site consists primarily of mowed lawn grass, with a small area of natural vegetation in the northern portion of project area.
The general land use in the vicinity of the project consists of residential development.
3b. List the total estimated acreage of all existing wetlands on the property:
N/A
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property -
±40 If
3d. Explain the purpose of the proposed project:
The purpose of the proposed project is to control flooding issues that currently occur at the project site.
3e Describe the overall project in detail, including the type of equipment to be used:
Currently, a LIT to Turkey creek flows south into a 30" pipe which flows into a stormwater collection system along Rattle
Snap Court and ultimately discharges into Turkey Creek. The 30" culvert is undersized for the volume of stormwater
during high flow events and causes flooding upstream and in the surrounding area. The flooding was such an issue that
the project site was previously a house /yard that flooded so often that Town of Cary actually purchased the house and lot
from the property owner. The project proposes to replace the 30" pipe with a grassed swale which will discharge into a
48" pipe, which then discharges into the stormwater collection system. The grassed swale will essentially create an
additional ±135 If of open channel which is currently contained within the 30° pipe. A flood storage area will also be
constructed within the empty lot adjacent to the grassed swale to allow for storage of excess stormwater during storm
events to contain excess stormwater runoff in order to protect the adjacent lots from flooding. Also as part of the project,
existing rip -rap within the stream at the upstream end of the existing culvert will be replaced with new rip -rap, and
additional rip -rap will be placed outside of the channel in order to prevent erosion during periods of high flow /storm
events.
Standard commercial construction equipment will be used to construct the proposed project.

Due to the nature of the project, impacts to streams and buffers could not be avoided. Buffer impacts have been minimized by
designing the project to primarily impact the mowed lawn grass buffers, within minimal impacts to native vegetation buffers.
The proposed flood storage area is necessary to contain excess stormwater during storm events in order to protect the
adjacent properties from flooding, which is currently the case.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.

No. It is much shorter. The existing 30" pipe discharges directly into the stream. The
proposed design has the 48" culvert discharging into a grassed swale, which the discharges
into the stream.

applicability confirmation
Craig,
We are working for the Town of Cary for improvements to the stormwater conveyance on
Rattle Snap Court in Cary, Wake County. Below is a Bing Maps link of the location of the
project.
http: / /binged.it /MUU5DX
Currently, there is a 30" pipe that discharges stormwater from the stormwater collection
system along Rattle Snap Ct a stream to the north. The 30" culvert is undersized for the
volume of stormwater during high flow events and causes flooding upstream. The project
proposes to replace the 30" pipe and direct discharge with a 48" pipe which will discharge
into a grass swale before discharging into the stream. A flood storage area will also be
constructed within the empty lot adjacent to the grassed swale to allow for storage of
stormwater during periods of high flow. I have attached a plan of the proposed project
design. The design proposes rip -rap below the grassed swale to dissipate flow velocity
and prevent erosion. There is currently rip -rap below the outfall of the existing 30"
pipe as exhibited on the attached Impact Plan as "Ex RIPRAP ". I have also attached photos
of the existing rip -rap below 30" pipe outfall. The project proposes the replacement of
the existing rip -rap with new rip -rap, which is noted as "Existing Stream Impact" on the
attached Impact Plan. The existing rip -rap extends well beyond the proposed rip -rap
replacement. Since the project proposes the replacement of existing rip -rap and no
additional stream impacts are needed, it is my understanding that the project meets the
conditions of a NWP 3 for Maintenance.
I am requesting concurrence that the project is authorized under a NWP 3 without formal
notification through submittal of a PCN.
Thanks for your help and feel free to contact me if you have any questions or need
additional information.
