On behalf of Glenn)an Inc, LLC we are requesting authorization from the USACE to
use NWP's 12 & 39 for the construction of a residential subdivision. We are also
requesting 4o1-Certification and Buffer Compliance from the NC-DWQ for the impacts
to jurisdictional waters and wetlands.
The subject property is approximately 11o acres in size and is located immediately
west of Hebron Church Road (SR 2547), approximately looo feet west of the
intersection of Ackerman Road (SR 2709) and Hebron Church Road. Latitude:
35.6653988°N and Longitude: 78.5831386°W in Garner, Wake County, North
Carolina. The site contains unnamed tributaries to Mahlers Creek and is located in
the Neuse River Basin. The Water Quality Classification for these features is: C;NSW,
the Cataloging Unit for this site is: o3ozo2oi, and the Stream Index number is: 27-
43-9•
Project History
Wetlands were delineated by Soil and Environmental Consultants. Site meetings
were conducted with the NC-DWQ on November 12, 2004 (DWQ EXP# 04-1793) and
February 14, 2005 (DWQ EXP# 05-0241) to verify stream origin points and subjectivity
to the Neuse Buffer Rules. On January 10, 2007, apre-application meeting was
conducted with the NC-DWQ to review the proposed impacts to the riparian buffers
necessary to provide stormwater management for the site (i.e. constructed
wetlands). DWQ agreed that due to topographic constraints, impacts to Zone 2 of
the Riparian Buffer could not be avoided.
Proposed Impacts
The proposed permanent impacts consist of 241 linear feet of jurisdictional stream
channel (131 l.f. unimportant/intermittent channel + 110 l.f. of important/perennial
channel) and o.017 acres of wetland for road construction. Temporary impacts
include 30 linear feet of important/perennial channel for the installation of a utility
line. In addition, approximately o.92 acres of riparian buffer will be impacted for the
installation of roadways, utility lines, and stormwater BMP's. The impacts are

summarized on the overall impact map as well as the PCN form.
Avoidance and Minimization
Prior to site plan development, the applicant requested that a detailed wetland
delineation be conducted so that impacts to wetlands and `waters' could be
minimized. Impacts were minimized by crossing the channel at a nearly
perpendicular angle and through the use of steeper fill slopes at the stream
crossings. The initial plans proposed impacts to Zone 1 of the Riparian Buffer for
BMP devices, however, based on comments from DWQ and additional review, we
were able to eliminate these impacts completely.
Stormwater Management Plan
The proposed impervious for this project is expected to be approximately 30%,
therefore constructed wetlands will be used to treat the Stormwater before it leaves
the site. A copy of the Stormwater plans is included with the attachments. During
construction the applicant will utilize BMP devices to prevent sediment from entering
jurisdictional stream channels or wetlands.
Mitigation
Because impacts to perennial channels are less than i5o linear feet and wetland
impacts are less than o.l acres, we do not believe that mitigation will be required.
However, because crossing D is greater than i5 degrees from perpendicular, the he
applicant proposes payment to the NC-EEP to satisfy mitigation requirements for
buffer impacts.
Please feel free to call if you have questions or require additional information.
Sincerely,
WITHERS & RAVENEL, INC.

11. Explain the purpose of the proposed work: The project is intended to meet the rowing
demand for housing in the area.
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. Wetlands were delineated by Soil and Environmental Consultants. Site
meetings were conducted with the NC-DWQ on November 12, 200.4__ (DWQ EXP# 04-1793) and
February 14, 2005 (DWQ EXP# OS-0241) to verify stream origin points and subjectivity to the
Neuse Buffer Rules. On January 10, 2007, apre-application meeting was conducted with the
NC-DWQ to review the proposed impacts. It was agreed that, due to topographic constraints and
in order to provide stormwater management for the site, (i.e. constructed wetlands) impacts to
Zone 2 of the Riparian Buffer could not be avoided.
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.
No additional impacts are proposed at this time. We have reviewed the additional stream
crossings needed to develop this parcel and it appears that these crossings could be accomplished
through the use of arch culverts and therefore would not require any additional impacts.
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 permanent impacts
consist of 241 linear feet of jurisdictional stream channel (131 l.f. unimportant/intermittent
channel + 110 l.f. of important/perennial channel) and 0.017 acres of wetland for road

Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): NA
Current land use in the vicinity of the pond: 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 maybe 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. Prior to site plan development,
the applicant requested that a detailed wetland delineation be conducted so that impacts to
wetlands and `waters' could be minimized. Impacts were minimized by crossing the channel at a
nearly perpendicular angle and through the use of steeper fill slopes at the stream crossing.
The initial plans proposed impacts to Zone 1 of the Riparian Buffer for BMP devices however
based on comments from DWO and additional review we were able to eliminate these impacts
completely. In addition, the crossings are located at a point where the stream channel contained
very few meander bends, thereby minimizin tg he impacts.
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 1 S, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
Page 5 of 8

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.uslncwetlands/stnn~ide.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
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Because impacts to perennial channels are less than 150 linear feet and wetland impacts are less
than 0.1 acres, we do not believe that mitigation will be required However because crossing D
is more than 15 degrees from~erpendicular the he applicant proposes ~ayment to the NC-EEP
to satisf~i~ation requirements for buffer impacts.
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://h2o.enr.state.nc.us/wrp/index.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): NA
Amount of buffer mitigation requested (square feet): 30,498
Amount of Riparian wetland mitigation requested (acres): NA
Amount ofNon-riparian wetland mitigation requested (acres): NA
Amount of Coastal wetland mitigation requested (acres): NA
IX. Environmental Documentation (required by DWQ)

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.
1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 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 multinliers.

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. Because impact `D' is not a perpendicular
crossing. the applicant nronoses navment to the NCEEP in order to satisfy mitigation
requirements. The applicant will be required to mitigate for 30,498 SF of buffer.
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 properly. If
Page 7 of 8

percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed
impervious level. This site is located in the Swift Creek Watershed and therefore, the percent impervious
cannot exceed 30% as mandated by the Town. The applicant will utilize constructed wetlands to treat
stormwater before it leaves the site.
XII. 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.
Sanitary Sewer
XIII. 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
XIV. 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: Because
this project consists of residential development, we do not believe that it will result in additional
impacts to downstream water quality. During construction the applicant will employ the
appropriate BMP's in order to reduce the amount of sediment leaving the site. Following
construction the applicant will convert these structures to constructed wetlands so that
stormwater from the c=site can be treated before it is released in the stream channels and
wetlands.
XV. 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).

delineated and flagged in the IIeld as the followlag: Feature A starts at flag "start NBR 100",
Feata~re C starts at flag "start N8R 200". Feature J is not subject to the Nense Buffer Rule. These
features and their associated bu~fexs should be idemtafied on, any future plans for dais pzoperty. The owner

1 am providing this letter in reference to the proposed White Oaks Farm Subdivision to
confirm the Town of Garner's ordinance requirements for street connectivity within and
between subdivisions. Street connectivity is critical to protect the safety and welfare of
our citizens and to the efficient delivery of municipal services, therefore we have
specific provisions in our land development regulations requiring street connectivity.
The White Oak Farms Subdivision, as proposed, meets the minimum requirements for
connectivity in Gamer. We would have significant concerns with further reducing the
connectivity points into future growth areas of the Town oi'Garner.
We appreciate your consideration of this matter.
Sincerely,
~~,d ~~~

The purpose of this letter is to notify you that the North Carolina Ecosystem Enhancement Program (NCEEP) is willing to
accept payment for impacts associated with the above referenced project. Please note that this decision does not assure that
the payment will be approved by the permit issuing agencies as mitigation for project impacts. It is the responsibility of the
applicant to contact these agencies to determine if payment to the NCEEP will be approved.
This acceptance is valid for six months from the date of this letter and is not transferable. If we have not received a copy of
the issued 404 Permit/441 Certificatlon/CAMA permit within this time frame, this acceptance will expire. It is the
applicant's responsibility to send copies of the permits to NCEEP. Once NCEEP receives a copy of the permit(s) an invoice
will be issued based on the required mitigation in that permit and payment must be made prior to conducting the authorized
work. The amount of the In Lieu Fee to be paid to NCEEP by an applicant is calculated based upon the Fee Schedule and
policies listed at www.nceep.net.
Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the
followin¢ table.

Upon receipt of payment, EEP will take responsibility for providing the compensatory mitigation. If the regulatory agencies
require ntigation credits greater than indicated above, and the applicant wants NCEEP to be responsible for the additional
mitigation, the applicant will need to submit a mitigation request to NCEEP for approval prior to permit issuance. The
mitigation will be performed in accordance with the Memorandum of Understanding between the N. C. Department of
Environment and Natural Resources and the U. S. Army Corps of Engineers dated November 4, 1998.
If you have any questions or need additional information, please contact Kelly Williams at (919) 7111-1921.

OPERATIONS & MAINTENANCE MANUAL
Project:
White Oak Farms
BEST MANAGEMENT PRACTICES 1, 2 & 3
Owners: Glennjan, LLC
Address: 8200 White Oak Road
Phone Number: 919-971-2619
Prepared by: Withers & Ravenel, Inc
Date: April 23, 2007
Project: White Oak Farms
Constructed: n/a
Location: Hebron Church Road, Garner NV
This manual establishes procedures for maintenance and operation of the White Oak Farms Best
Management Practices (BMP) 1, 2 & 3 in accordance with NCDENR rules and regulations.
SECTION 1 -MAINTENANCE OF BEST MANAGEMENT PRACTICES
Monthly or after every runoff producing rainfall, whichever comes first:
a. Remove debris from trash racks
b. Check and clear orifice and riser of any obstructions. The detention device should be
kept clear of debris such as loose bottles, cans, food containers and other forms of
rubbish. Any rodents that have fallen into the device should be removed so that they do
not present a source of blockage for the discharge pipe.
c. Check pond side slopes; remove trash, repair eroded areas before next rainfall. Rills
and gullies should be filled with suitable soil compacted and then seeded. Where
eroded areas are detected, the cause of the erosion should be addressed to prevent a
continued maintenance problem.
II. Quarterly
a. Inspect the collection systems (i.e., catch basin, piping, grassed swales) for proper
functioning. Clear accumulated trash from basin grates, and basin bottoms, and check
piping for obstructions.
b. Check pond inlet pipes for obstructions.
c. Repair any broken pipes.
d. Replace riprap that is choked with sediment.
III. Semi-Annually
a. Remove accumulated sediment from bottom of outlet structure.
b. Check pond depth at various locations. If the elevations of the marsh areas exceed the
permanent pool elevation, the sediment should be removed to design levels. This shall
be performed by excavating the marsh areas six inches below design elevations.
Afterwards clean topsoil shall be placed to bring marsh areas back to design elevations
and the required plant material reestablished. (see elevation tables below)
c. The riser structure should be visually inspected semi-annually for any seepage through
mortar joints or cracks in the walls of the structures. The orifice outlets should be
cleared of any debris that may build up and the extension should be checked for

damage. The drain valve assembly should be operated to ensure that all internal parts
remain lubricated and in good working order.
d. Conduits should be visually inspected at the joints. Pipes should be inspected for
proper alignment (sagging), elongation and displacement at joints, cracks, leaks,
surface wear, loss of protective coating, corrosion and blocking. A depression in the
soil surface over the pipe may be signs that soil is being removed from around the pipe.
IV. General
a. Mow side slopes according to the season. Maximum grass height to be six (6) inches.
b. Wetland planting densities in the marsh areas should be maintained by replanting bare
areas as needed. Wetland plants should be encouraged to grow in the marsh areas.
c. All components of impoundment system to be kept in good working order.
d. In case the ownership of the impoundments transfers, the current owner shall, within
thirty (30) days of transfer of ownership, notify NCDENR-DWQ of such ownership
transfer.

SECTION 2 -RECORD KEEPING
Operation of the storm water detention device should include recording of the following:
Semi-Annual Inspection Reports - A collection of written inspection reports should be kept on
record in Section 3 of this manual. Inspection should be conducted semi-annually.
Observations -All observations should be recorded. Where _periodic inspections are
performed following significant rainfall, these inspections should be logged into the Periodic
Inspection, Operations and Maintenance Form in Section 3 of this manual.
Other Operational Procedures -The owner should maintain a complete and up-to-date set of plans
(as-built drawings) and all changes made to the detention device over time should be recorded on
the as-builts.
Sedimentation and Dredging -Sedimentation from on-site and off-site soils will eventually result in
a decrease of the storage capacity for these ponds and will have to be removed. The frequency of
this sediment removal can be reduced by ensuring that the site areas be stabilized with a
vegetative ground cover such that it restrains erosion. This would include a periodic application of
fertilizer and/or other treatment necessary to promote a stable ground cover and minimize
sedimentation to the device. The removed material should be hauled offsite to a suitable landfill
site or mounded somewhere on site and stabilized with a ground cover sufficient to restrain
erosion.
I, ,Member ,hereby acknowledge that I am the financially responsible
party for Maintenance of these Best Management Practices. I will perform the maintenance as outlined
above, as part of the 401 Water Quality Certification and the stormwater regulations for this project.
