Town Manager, Town of Fuquay-Varina
401 Old Honeycutt Road
Fuquay-Varina, NC, 27526
APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Ellis:
You have our approval, in accordance with the attached conditions, to place permanent fill in 0.45 acre of wetl rids in
order to construct two road crossings associated with the Lakestone Parkway project in Wake County, as described in your
application received by the Division of Water Quality on May 30, 2003. After reviewing your application, we have
determined that this fill is covered by General Water Quality Certification Number 3404, which can be viewed on ou web
site at htto://h2o.enr.state.nc.us/ncwetiands. This Certification allows you to use Nationwide Permit Number 14 wh n it is
issued by the U.S. Army Corps of Engineers.. This approval is also valid for the Neuse River Buffer Rules (15A NC C 2B
.0233). In addition, you should get any other federal, state or local permits before you go ahead with your project in luding
(but not limited to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. Also t is
approval will expire when the accompanying 404 permit expires unless otherwise specified in the General Certificat n.
This approval is only valid for the purpose and design that you described in your application. If you change yo r
project, you must notify us in writing and you may be required to send us a new application for a new certification. I the
property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby respons ble for
complying with all conditions. If total wetland and/or stream fills for this project (now or in the future) including futur phases
of this subdivision exceed one acre or 150 linear feet of perennial streams, compensatory mitigation may be requir d as
described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed in the atta hod
certification, as well as the additional conditions listed below:
1. You are required to return the attached Certification of Completion form to notify DWQ when all work included ih the 401
Certification has been completed;
2. The culvert required for this project shall be installed in such a manner that downstream profiles are not altere (i.e. the
depth of the channel must not be reduced by a widening of the streambed). Existing stream dimensions (inclu ing the
pattern and profile) are to be maintained above and below locations of each culvert. The culverts shall be desi ned and
installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the exis ing pipes
are or become perched, the appropriate stream grade shall be re-established or, if the pipes installed in a perc ed
manner, the pipes shall be removed and re-installed correctly.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You ust act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, Mail Service Center 6714,
Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. I you have
any questions, please telephone Steve Mitchell in DWQ's Raleigh Regional Office at 919-571-4700 or Cyndl Karo in the
Central Office in Raleigh 919-733-9721.

Lakestone Parkway C
Fuquay-Varina, Wake County, North Carolina
S&EC Project #: 6941.01 MAY '
NATEH ,?_,WAIATY SECTION
Dear Ms. Wade and Mr. Dorney:
On behalf of the Town of Fuquay-Varina (applicant), we hereby request authorization
from the US Army Corps of Engineers (USACE) to use Nationwide Permit 14 to cover
impacts to two wetland features. We also request written concurrence from the North
Carolina Division of Water Quality (NC-DWQ) that the project complies with the 401
Water Quality Certification associated with Nationwide Permit 14. A Pre-construction
Notification Application (PCN) is attached, as well as an agent authorization form.
The proposed project consists of the construction of Lakestone Parkway, a proposed road
that is included Town of Fuquay-Varina's Thoroughfare Plan (see attached). The
proposed Lakestone Parkway is approximately 3300 linear feet in length and will connect
US 401 to Old Honeycutt Road (SR 2765) (see Fig. 3). The location of the proposed
corridor is depicted on the attached USGS map (Fig. 1) and Soil Survey map (Fig. 2).
S&EC conducted a delineation of the proposed corridor for Lakestone Parkway and the
surrounding area in 2002. Ms. Amanda Jones approved this delineation on 12/9/02 (AID
200220660). In a letter dated January 10, 2003, Ms. Deborah Edwards of NC-DWQ
determined that feature B becomes subject to the buffers at flag 110, downstream from
impact #2 (see soil survey map and attached plan). Feature A was ddterinined to be-.xot
subject to the buffers. No permits have been requested for this project prior to this
application.

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. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, pennanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must 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.

5. 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.

Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): 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 applicant requested a delineation of wetlands in the vicinity of the proposed Lakestone
Parkway corridor in order to minimize impact to jurisdictional features to the maximum extent
practical Lakestone Parkway is a proposed collector street shown on the Town of Fuquay-
Varina Thoroughfare Plan that will connect US 401 / Main Street to Old Honeycutt Road (SR
2765) Two wetland features separate Old Honeycutt Road from US 401, making it necessary to
impact both jurisdictional areas in order to provide the connection required by the thoroughfare
plan In an effort to minimize impact, the project engineer has aligned the proposed parkway to
cross both wetland features perpendicularly at their narrowest points (see attached plan) and
avoid the strea channel and riparian buffer at impact area #2. S&EC believes that the applicant
has aligned the thoroughfare to minimize impact to wetlands and avoid stream channels and
riparian buffers to the maximum extent practicable However, if the USACE determines further
mitigation is necessary, the applicant proposes payment into the NCWRP and / or preservation of
wetland areas in the vicinity of Lakestone Parkway at a ratio of 5:1.
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
Page 5 oft)
Amount of Riparian wetland mitigation requested (acres): 0.45 acres (if required by
USACE and USACE determines 5:1 preservation on-site will not satisfy mitigation
requirement
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ? No
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at (919) 733-5083 to review current thresholds for environmental documentation.
Yes ? No ?
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?

Dear Mr. Preuninger:
This letter will serve as confirmation of the buffer determination made by S&EC at the
subject property referenced by the Raleigh Regional Office as NBRRO 03-006.
On August 27, 2002, 1 conducted a site visit of features A, B, C and ponds 1, 2 and 3
involved in the above referenced project as identified on the attached figures 1 and 2. It was
determined that the features shown on the Wake County Soil Survey and on the USGS Fuquay-
Varina, NC Quad map could potentially be subject to protection under the Neuse River Basin:
Nutrient Sensitive Waters Management Strategy; Protection and Maintenance of Existing Riparian
Areas, Administrative Code T15A: 0213.0233 (NCAC .0233). Features A and C are not subject.
Feature B is subject from flag 110 to flag U42. Ponds 1, 2 and 3 are all subject.
This letter only addresses the applicability of the Neuse Buffer Rules. For information
relevant to wetlands and other impacts, please contact the Central Office at 733-1786. Thank you
for your attention to this matter and if this office can be of any assistance or if you have additional
questions, please do not hesitate to contact us.
Sincerely,
