Re: Summer Lakes Drive Storm Drainage Improvements - Cary, Wake County
NWP 14 PCN Submittal
WR Project #02050400.17
Dear Ms. Alexander and Ms. Higgins,
On behalf of the Town of Cary, we are requesting authorization from the USACE to use NWP 14 for
40 If of permanent stream impacts and 40 If of temporary stream impacts for improvements to the
existing culverted stream crossing on Summer Lakes Drive. We are also requesting a 401 WQC
from NCDWR for the above referenced impacts, as well as a Buffer Authorization for 3,477 sq ft of
permanent buffer impacts and 1,184 sq ft of temporary buffer impacts.
The project is located on Summer Lakes Drive (Latitude: 35.7919°N; Longitude: -78.8304°W) in the
Preston Fairways Subdivision in Cary, Wake County. The proposed project is located in the Neuse
River basin (HUC 03020201) and the proposed impacts will occur to an unnamed tributary to
Crabtree Creek. The Water Quality Classification for Crabtree Creek is C;NSW, and the Stream
Index is: (27-33-(1).
Proposed Proeect
The purpose of the proposed project is to improve the storm drainage at this crossing to alleviate
frequent flooding issues. The proposed project consists of the replacement of the existing
undersized culverts with a 25x5 ft box culvert. The existing rip -rap dissipator on the downstream
side of the culvert will be removed and replaced. Additionally, a rip -rap apron will be installed on
the upstream side of the culverts to prevent erosion and undercutting of the new box culvert.
Project History
WR reviewed the project area in January 2015 for the presence of wetlands and streams. There
are no wetlands within the project area. The project area contains a single jurisdictional
intermittent stream, consisting of an unnamed tributary to Crabtree Creek.

The intermittent stream within the review area is depicted on both the USGS Quad and Wake Co.
Soil Survey and subject to riparian buffers was conceded. Therefore, a formal Buffer Determination
was not requested from NCDWR.
Proposed Impacts
The proposed impacts will occur to an intermittent stream between two ponds associated with the
golf course. The majority of the stream has been historically lined with rip -rap.
The proposed impacts consist of 40 If of permanent stream impacts and 40 If of temporary stream
impacts, as well as 3,477 sq ft of permanent riparian buffer impacts and 1,184 sq ft of temporary
riparian buffer impacts.
The proposed 40 If of permanent stream impacts (Impact #1) will occur from construction of a rip -
rap apron on the upstream end of the culvert to stabilize the area to prevent erosion and
undercutting of the new culvert.
The proposed 40 If of temporary stream impacts (Impact #2) will occur from removal of the existing
rip -rap dissipator and replacement with new rip -rap.
The proposed 3,477 sq ft of permanent riparian buffer impacts (Zone 1: 2,966 sq ft; Zone 2: 511 sq
ft) will occur from placement of rip -rap within the buffers to armor the banks of the stream to
prevent erosion, as well as to protect the outfalls of the existing stormwater collection system for
Summer Lakes Drive.
The proposed 1,184 sq ft of temporary riparian buffer impacts (Zone 1: 1,184 sq ft; Zone 1: N/A)
will occur during construction for temporary construction access. It is not anticipated that the
buffers will be heavily disturbed during construction, as construction equipment will be primarily
operated from the existing roadway.
Avoidance and Minimization
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted
so that impacts to wetlands and "waters" could be minimized.
The proposed culvert will be installed in the same footprint of the existing culverts. Retainingwalls
will be constructed to stabilize fill, minimizing impacts from traditional back slopes.
Proposed permanent stream impacts have been minimized to only those impacts necessary for
construction of a rip -rap apron on the upstream side of the culvert to stabilize the area and prevent
erosion and undercutting of the new box culvert.
Coffer dams will be installed and the flow of the stream will be pumped around the construction
area so that work will be completed in the dry. The coffer dams will be installed within the

permanent impact area associated with the rip -rap aprons to avoid temporary impacts to the
stream outside of the permanent impact areas.
Proposed permanent buffer impacts have been minimized to those impacts necessary for
placement of rip -rap to protect the new culvert and stormwater outfalls associated with the
existing stormwater collection system.
Due to the nature of the proposed project, impacts could not be further minimized or avoided.
Mitigation
Since the proposed permanent stream impacts are less than 150 If, the applicant is not proposing
stream mitigation.
The proposed buffer impacts are listed as "Allowable" in the Neuse River Riparian Buffer Rules'
Table of Uses, and therefore, buffer mitigation is not proposed.
Stormwater Management Plan
The proposed project consists of maintenance of an existing road crossing by replacing the existing
undersized culverts with a larger box culvert to alleviate flooding issues. The project will not result
in any new impervious area that requires stormwater management, and the existing stormwater
management system and outfalls will be maintained. Therefore, a stormwater management permit
is not required.
The current request is for 40 If of permanent stream impacts, 40 If of temporary stream impacts,
3,477 sq ft of permanent buffer impacts and 1,184 sq ft of temporary buffer impacts. (see
attached PCN and exhibits for details).
Please feel free to call if you have questions or require additional information.
Sincerely

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands
and "waters" could be minimized.
The proposed culvert will be installed in the same footprint of the existing culverts. Retaining walls will be constructed to
stabilize fill, minimizing impacts from traditional back slopes.
Proposed permanent stream impacts have been minimized to only those impacts necessary for construction of a rip -rap apron
on the upstream side of the culvert to stabilize the area and prevent erosion and undercutting of the new box culvert.
Coffer dams will be installed and the flow of the stream will be pumped around the construction area so that work will be
completed in the dry. The coffer dams will be installed within the permanent impact area associated with the rip -rap aprons to
avoid temporary impacts to the stream outside of the permanent impact areas.
Proposed permanent buffer impacts have been minimized to those impacts necessary for placement of rip -rap to protect the
new culvert and stormwater outfalls associated with the existing stormwater collection system.

PCN Form — Version 1.3 December 10, 2008 Version

Due to the nature of the proposed project, impacts could not be further minimized or avoided.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Retaining walls will be used to stabilize fill for the road crossing. Coffer dams will be constructed within the permanent impact
areas associated with the rip -rap apron to avoid temporary stream impacts beyond the impact areas. Silt fencing will be
installed around all disturbed areas to prevent sediment from escaping into the stream and adjacent buffers.
