S&EC Project #: 97-3165.W1 AUG 0 2005
Dear Mr. Matthews and Ms. Van Der Wiele: eE? ?9SJEAPLIB
vtET?°S
On behalf of Brier Creek Corporate Center, we request a revision to the previously issued US
Army Corps of Engineers (USACE) Nationwide Permit (NWP) 14 for the proposed project to
cover permanent impacts to wetlands. We also request written concurrence from the NC
Division of Water Quality (NCDWQ) that the project complies with the 401 Water Quality
Certification required under NWP 14. A Pre-construction Notification Application (PCN) is
attached, which includes an agent authorization form. This application has been revised due to
a realignment of the road at Impact area 5. All other aspects of the previously approved
project will remain the same. The revision results in 0.01 acre less impact.
The proposed project consists of installation of infrastructure necessary to support future
commercial development, such as an access road. The site is located in the northern quadrant of
the intersection of Lumley Road and Interstate 540. Please refer, to the attached map (Figure 1)
for the location of the proposed project on a USGS topographic quadrangle.

Since the client has been approved for payment to EEP for previously approved impacts and
because the current proposed change results in less impact than that previously approved, no
additional mitigation should be required.

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, permanent
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
Page 3 of 8
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.

List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging,
flooding, drainage, bulkheads, etc.
4. 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.): NA
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): NA
Size of watershed draining to pond: NA Expected pond surface area: NA
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.
This road impact was previously approved but the client desires to shift the road sliuhtly west
which actually results in 0.01 acre less impact than previously authorized.
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 March 9, 2000, 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
Page 5 of 8
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 NCWRP 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/strrngide.htm].
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
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The applicant has made payment to the NCEEP for 0.5 acres of wetland impact.
Since this revision results in less wetland impact, no additional mitigation should be required.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three 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 (0.5 acre previously paid)
Amount of Non-riparian wetland mitigation requested (acres): 0
Amount of Coastal wetland mitigation requested (acres): 0
IX. Environmental Documentation (DWQ Only)
Does the project involve an expenditure of public funds or the use of public (federal/state/local)
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)?
Page 6 of 8
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] 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 (DWQ Only)
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 )?
Yes ® No ? If you answered "yes", provide the following information:
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.
Zone* Impact
(square feet) Multiplier Required
Mitigation
Impact 5
1 0 3 0
2 0 1.5 0
Total 0 0
* Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 213.0242 or.0260.
None required.
Page 7 of 8
XI. Stormwater (DWQ Only)
Describe impervious acreage (both 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.
The site is currently undeveloped and does not contain impervious acreage. There are three lots
within Parcel J located outside of the floodplain area that are planned for commercial
development. Once developed, each lot is expected to consist of 70-75% impervious area.
However, the impervious area of the entire Parcel is estimated to be 41% based on preliminary
plans. Riparian buffers, an undisturbed floodplain, and compliance with the City of Raleigh's
Local Stormwater Program for Nitrogen Control are expected to protect surface waters and
wetlands downstream of the property. Since there is no current site plan for the lots, we propose
that DWQ condition the 401 to require stormwater plan approval prior to site grading:
Stormwater plans for the road by the John R. McAdams Company are attached.
XII. Sewage Disposal (DWQ Only)
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.
Municipal sanitary sewer system
XIII. Violations (DWQ Only)
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
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).

To: Ms. Cynthia Van Der Wiele
From: Brandon G. Plunkett, P R1?5?
Re: Brier Creek Corporate Center
Dear Ms. Van Der Wiele,
Brier Creek Corporate Center Associates, LP respectfully requests a revision
to the previously permitted wetland impacts at the proposed Brier Creek
Corporate Center Development.
In the weeks following the issuance of the permit, the developer has begun
working on site layouts for the first phase of their development. In order to
maximize the amount of parking required for this first phase, the developer
would like to shift the roadway to the west in the vicinity of impact #5. This
revision is shown on the revised impact maps. Please note, this revision does
not change the amount of wetland area impacted over that previously
permitted.
If you have any questions regarding the above referenced project or the
revisions, please do not hesitate to give me a call.

Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. if a requirement has not been met, attach an explanation of why. At a minimum, a
complete stormwater management plan submittal includes a worksheet for each BMP, design calculations, plans and
specifications showing all BMPs and outlet structure details, a detailed drainage plan and a fully executed operation
and maintenance agreement An incomplete submittal package will result in a request for additional information and
will substantially delay final review and approval of the project
Applicants Initials
Level spreader is at least 13 ft per cfs for thick ground cover or grass or 100 ft per ds in canopied forest
with leaf Etter.
Pre-Form Scour Holes are on flat slopes only
No structures are located in protected buffers`
If bypass method specified in the Draft Level Spreader Design Option Document:
Bypass method is specified (if applicable) and plan details and calculations are provided
Discharge to level spreader and subsequent filter strip is hydraulically and spatially separate from the
bypass discharge.
No structures are located in protected buffers.
Plan details for the bypass and outlets are provided.
The operation and maintenance agreement includes annual erosion and vegetation repair.
The operation and maintenance agreement signed and notarized by the responsible party is provided
Level spreaders in series can be used on slopes of up to 15% in forested areas with leaf littler cover or on slopes of
up to 25% in areas with thick ground cover or grass if designed according to the Draft Level Spreader Design Option
Document This potentially requires a minor variance in protected buffer areas. In any event the second level spreader
cannot be located in Zone 1 of a protected buffer area.
