DENR • WADER QUAl1TY
Dear Sirs: WOODS AND STORMWATER BRMCH
We received NC Division of Water Quality's letter requesting additional information regarding
the subject project application dated March 18, 2008. On March 28, 2008, we also received an
email from Mr. Jamie Shern of the USACE indicating permit conditions required for using
preservation to satisfy mitigation requirements and pre- and post-construction inspection
requirements of 149 linear feet of stream channel impact after discussing these and other points
via telephone. The project engineer, Mr. Keith Roberts, has revised the project plans, which are
reflected in the revised PCN application attached. Approximately two weeks ago, I contacted
Mr. McMillan to determine if the delay in providing this response required re-application. He
explained that if we had not received a letter returning our application then only the additional or
revised information would be necessary.
This PCN application has been revised to include additional justification for the unavoidable,
non-perpendicular road crossing, avoid wetland impacts #4 through #6, reflect the new culvert
size, provide a cross-section view of the proposed road crossing showing the headwall height,
permanent stormwater management BMPs, and preservation through the restrictive covenants for
the subdivision. Five copies of the revised PCN application and new attachments are attached to
NCDWQ's package along with two paper copies of the stormwater management plans and a
digital one on CD.

landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.

acre property into approximately 250 individual lots for single-family home construction.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. Burdette Land Consulting Inc. (BLC) conducted a surface water and
wetland delineation of the property during April 2006 The wetland boundary has not been
verified by the USACE An Approved Jurisdictional Determination Form and supporting
Wetland Data Forms for the relevant reach to which impacts are proposed were attached to the
original PCN application submitted on March 12, 2008. On March 18, 2008, we received a letter
from NCDWQ requesting more information regarding the stormwater management and the
nonperpendicular angle of the road crossing. On March 28, 2008, we received an email from
Jamie Shern of the USACE indicating permit conditions required for using preservation to
satisfy mitigation requirements and pre- and post-construction inspection of requirements of
impacts of 149 linear feet of stream channel after discussing these and other points via telephone.
This PCN application has been revised to include additional justification for the unavoidable,
non-perpendicular road crossing avoid wetland impacts #4 through #6 reflect the new culvert
size permanent stormwater management BMPs and preservation through the restrictive
covenants for the subdivision.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
This PCN application covers the all phases of the project; therefore, future permit requests are
not anticipated for this project.

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. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should 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.
1. Provide a written description of the proposed impacts: The proposed impacts include a
road crossing of a stream channel and its adjacent wetland and two other relatively small
wetland impacts resulting from road and lot fill. Please refer to the Impact Maps for the
details of each impact.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding_

7. Isolated Waters
Do any isolated waters exist on the property? ? Yes ® No
Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
NA - isolated waters are not present on the property
8. 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.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): see attached stormwater management plans
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): see attached stormwater management plans
Current land use in the vicinity of the pond: see attached stormwater management plans
Size of watershed draining to pond: see above Expected pond surface area: see above
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
Page 5 of 10
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 surface waters and wetlands prior to preliminary plan development to avoid
impacts to jurisdictional areas to the maximum extent practicable However, one stream channel
along with its abutting wetlands dissects the property making it unavoidable The engineer was
unable to align the road crossing labeled as Road Impact #1 perpendicularly due to site
constraints that are further explained in Mr. Keith Roberts' attached letter. By using headwalls
the engineer was still able to minimize the impact to the channel to less than 150 linear feet A
cross-section showin the height of the headwall is attached The culvert will be buried to allow
aquatic life passage. Additionally, the middle culvert is centered on the stream channel and the
two side culverts will be installed at the bankfull elevation to maintain the stream channel's
original pattern, dimension, and profile. A cross-section of the culverts is provided as Figure 4
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
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
Page 6 of 10
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The applicant avoided impacts to streams and wetlands where possible and minimized stream
channel impacts that were unavoidable to the maximum extent practicable as described
above. A 50-foot-wide riparian buffer will be maintained around the stream channel present
within the development in accordance with Town of Fuquay-Varina's requirements and will
serve as a permanent, vegetative buffer to that stream channel.
BLC believes that compensatory stream channel mitigation should not be required for the
project because the unavoidable stream channel impact does not exceed the 150 linear foot
impact threshold established for mitigation by the NCDWQ and the USACE in most cases,
and the applicant has exercised every available option to minimize the impact. Because the
proposed jurisdictional wetland impact of 0.367 acre exceeds the USACE's (0.10 acre)
threshold for mitigation, BLC believes that riparian wetland mitigation is required.
The applicant proposes to mitigate jurisdictional wetland impacts at a 2:1 ratio through
preservation and compensatory mitigation. Compensatory mitigation for 0.367 acre of
riparian wetland impact will be satisfied through payment to the NCEEP. NCEEP's wetland
mitigation acceptance letter is attached. The remainin-g 0.367 acre of mitigation required
would be satisfied by preserving a large wetland area on the project and all of those wetlands
that will remain within lots through the subdivision's restrictive covenants using the
USACE's standard preservation language and the attached preservation map. (FigL ure 5).
Approximately 8.52 acres of wetland will be preserved on the site providing a preservation
ratio of approximately 23 to 1. It is important to note that 1824 linear feet of perennial
stream channel will also be preserved within the proposed wetland conservation area
providing stream channel preservation at a ratio of approximately 12 to 1.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://www.neeep.net/pages/inlicureplace.htm. If use of the NCEEP is proposed,
please check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): 0
Amount of buffer mitigation requested (square feet): 0
Amount of Riparian wetland mitigation requested (acres): 0.367
Amount of Non-riparian wetland mitigation requested (acres): 0
Amount of Coastal wetland mitigation requested (acres): 0

(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ? No
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multipliers.
I Zone* I Impact I Multiplier I Required
(sauare feet) . Mitigation
1 NA - Cape Fear 3 (2 for Catawba) NA - Cape Fear
2 NA - Cape Fear 1.5 NA -Cape Fear
Total I NA - Cape Fear I I NA -Cape Fear
* Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. NA - Cane Fear
Page 9 of 10
X. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. The site does not currently contain any
impervious acreage. The project engineer, Keith Roberts, PE has estimated that the overall
impervious acreage upon build-out will not exceed 23.8%. However, individual drainage areas
within the project do exceed 24 percent impervious surface area. Mr. Keith Roberts and I met
with Annette Lucas of NCDWO on April 17, 2008 to discuss the options for stormwater
management on the project. Ms. Lucas and Mr. Roberts worked out a plan to allow the
temporary sediment basins to convert to permanent wetlands for stormwater treatment Please
refer to the attached email and attached Stormwater Control Calculations for Pond 1 and 2 The
permanent stormwater BMPs and Town of Fuquay-Varina 50-foot riparian buffers around the
intermittent stream channel are anticipated to protect surface waters and wetlands downstream
from the property.
XI. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Wastewater generated from the proposed project will be disposed of through the Town of
Fuquay-Varina sanitary sewer system.
XII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application? Yes ? No
XIII. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ? No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: The
proposed infrastructure serves only the proposed residential development Therefore the project
is not anticipated to result in additional development
Page 9 of 10
XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).

RE: Grays Creek Subdivision
Buffer Crossing
The proposed Grays Creek Subdivision is bounded on the North by Wilbon Road and on the South by
Coley Farm Road. The parcel is divided by a creek that runs NW to SE through (diagonally) through the
site within an area where the parcel narrows. The creek is required to be buffered based on the Neuse River
Rules. Due to the fact that the tract has access to the North and the South the developer had requested that
the crossing through the buffer not be required. However, due to development guidelines within Fuquay-
Varina, the crossing is required. Fuquay-Varina is requiring the crossing due to the size of the subdivision,
entrance locations, emergency vehicle access and 500' limits on cul-de-sac lengths.
Due to site and development regulation constraints, it is impossible to cross the buffer perfectly
perpendicular. As mention previously the site runs North to South and the buffer runs NW to SE within the
narrowest part of the site. Additionally, the design street radius on either side of the buffer can not be
decreased due to design regulations within Fuquay-Varina. The proposed curve radius at the buffer is 200'.
The minimum allowed by code is 200' (see attached email). Based on the geometric configuration of the
site and design constraints we feel that the current layout best minimizes buffer impacts. We also tried to
further decrease impacts with the installation of headwalls on the upstream and downstream side of the
