APPROVAL of 401 Water Quality Certification and AUTHORIZATION CERTIFICATE per
the Neuse River Buffer Protection Rules (15A NCAC 2B .0233) with ADDITIONAL
CONDITIONS
EXPRESS REVIEW PROGRAM
Dear Sir or Madam:
You have our approval, in accordance with the attached conditions and those listed below, to
place fill within or otherwise impact 0.7852 acres of wetlands (0.4476 acres permanent, 0.3376
acres temporary), 155 linear feet of perennial streams (110' permanent, 45' temporary) and
33,181 square feet (ft) of protected riparian buffers (17,486 ft2 permanent, 15,695ft2 temporary)
for the purpose of a subdivision at the subject property, as described within your application
dated August 19, 2004 and all additional information submitted on August 23, 2004, September
1, 2004, September 10, 2004 and September 16, 2004. After reviewing your application, we
have decided that the impacts are covered by the N.C. Division of Water Quality (DWQ)
General Water Quality Certification Number 3402 (GC3402). The Certification allows you to use
Nationwide Permit 39 when issued by the US Army Corps of Engineers (USACE). This letter
shall also act as your approved Authorization Certificate for impacts to the protected riparian
buffers per 15A NCAC 2B .0233. In addition, you should obtain or otherwise comply with any
other required federal, state or local permits before you go ahead with your project including
(but not limited to) Erosion and Sediment Control and Non-discharge regulations. Also, this
approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in
your application shall expire upon expiration of the 404 or CAMA Permit.
This approval is for the purpose and design that you described in your application. If you
change your project, you must notify us and you may be required to send us a new application.
If the property is sold, the new owner must be given a copy of this Certification and approval
letter and is thereby responsible for complying with all conditions. If total fills for this project
(now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval requires you
to follow the conditions listed in the attached certification and any additional conditions listed
below.

Stream 155 feet WL-1.0 9/10/04
404 Wetlands 0.7852 acres WL-1.0 9/10/04
Buffers 33,181 (square
ft.) I WL-2.0 (9/10/04)
2. Erosion & Sediment Control Practices
Erosion and sediment control practices must be in full compliance with all specifications
governing the proper design, installation and operation and maintenance of such Best
Management Practices in order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed,
installed, operated, and maintained in accordance with the most recent version of
the North Carolina Sediment and Erosion Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion
control measures must be such that they equal, or exceed, the requirements
specified in the most recent version of the North Carolina Sediment and Erosion
Control Manual. The devices shall be maintained on all construction sites, borrow
sites, and waste pile (spoil) projects, including contractor-owned or leased borrow
pits associated with the project.
3. No Waste, Spoil, Solids, or Fill of Any Kind
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas
beyond the footprint of the impacts depicted in the Preconstruction Notice Application. All
construction activities, including the design, installation, operation, and maintenance of
sediment and erosion control Best Management Practices, shall be performed so that no
violations of state water quality standards, statutes, or rules occur.
4. No Sediment & Erosion Control Measures w/n Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters to the
maximum extent practicable. If placement of sediment and erosion control devices in
wetlands and waters is unavoidable, they shall be removed and the natural grade restored
within six months of the date that the Division of Land Resources has released the project.
5. Grading and Revegetation within Zone 2

The plans provided along with the application depict grading activities within Zone 2 of the
protected buffer. This activity is designated as "exempt" under the Buffer Rule provided that fill
is not placed in Zone 1, diffuse flow is maintained as per the Buffer Rule, the disturbed areas
are stabilized and revegetated, and the health of the existing vegetation in Zone 1 is not
compromised..

6. Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained jurisdictional
wetlands, waters and protective buffers in order to assure compliance for future wetland,
water and buffer impact. These mechanisms shall be put in place prior to impacting any
wetlands, waters and/or buffers approved for impact under this Certification Approval and
Authorization Certificate. A sample deed notification can be downloaded from the
401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of the sample
deed notification may be modified as appropriate to suit to this project.
7. Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered. Existing stream dimensions (including the cross section dimensions,
pattern, and longitudinal profile) must be maintained above and below locations of each
culvert. Culverts shall be designed and installed to allow for aquatic life movement as well
as to prevent head cutting of the streams. If any of the existing pipes are or become
perched, the appropriate stream grade shall be re-established or, if the pipes installed in a
perched manner, the pipes shall be removed and re-installed correctly.
Installation of culverts in wetlands must ensure continuity of water movement and be designed
to adequately accommodate high water or flood conditions.
8. Diffuse Flow
In an effort to comply with the diffuse flow provision of the Buffer Rule (15A NCAC 02B
.0233(5)), you have provided the DWQ with level spreader designs dated August 19, 2004
and September 1, 2004. The DWQ believes that if implemented, as per these plans, diffuse
flow will be achieved. However, if diffuse flow as per 15A NCAC 02B .0233(5) is not
achieved, then the DWQ shall be notified and corrective actions to restore diffuse flow shall
be taken if necessary to impede the formation of erosion gullies. At no time shall stormwater
from the proposed development be piped directly through the buffer without prior DWQ
written authorization.
9. Protective Fencing
The outside buffer, wetland or water boundary and along the construction corridor within
these boundaries approved under this authorization shall be clearly marked with orange
warning fencing (or similar high visibility material) for the areas that have been approved to
infringe within the buffer, wetland or water prior to any land disturbing activities to ensure
compliance with 15A NCAC 2B 33 and GC 3402.
10. Written Stormwater Management Plan (No Further Approval Needed)
The final, written stormwater management plans (including a signed and notarized
Operation and Maintenance Agreement) dated August 19, 2004 and August 23, 2004, must
be implemented and the stormwater management facilities shall be constructed and
operational before any permanent building is occupied at the subject site. The structural
stormwater practices as approved by this Office as well as drainage patterns must be
maintained in perpetuity. No changes to the structural stormwater practices shall be made
without written authorization from the Division of Water Quality.

Pre-Construction Notification (PCN) Application Form
For Section 404 and/or Section 10 Nationwide, Regional and General Permits, Section 401
General Water Quality Certifications, and Riparian Buffer and Watershed Buffer Rules
This form is to be used for projects qualifying for any of the U.S. Army Corps of Engineers' (USACE)
Nationwide, Regional or General Permits as required by Section 404 of the Clean Water Act and/or
Section 10 of the Rivers and Harbors Act, and for the North Carolina Division of Water Quality's
(DWQ) associated General 401 Water Quality Certifications. This form is also to be used for any
project requiring approval under any Riparian Buffer Rules implemented by the N.C. Division of Water
Quality. This form should not be used if you are requesting an Individual 404 Permit or Individual 401
Water Quality Certification. The USACE Individual Permit application form is available online at
http://www.saw.usace.army.mil/wetlands/Perm app.htm.
The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
USACE website at http://www.saw.usace.army.mil/wetlands/regtour.htm, or contact one of the field
offices listed on page 3 of this application. The website also lists the responsible project manager for
each county in North Carolina and provides additional information regarding the identification and
regulation of wetlands and waters of the U.S.
The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been determined by the USACE.
Applicants are encouraged to visit DWQ's 401/Wetlands Unit website at
http://h2o.enr.state.nc.us/ncwetlands to read about current requirements for the 401 Water Quality
Certification Program and to determine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for General Certifications is not required, provided
that the applicant adheres to all conditions of the GC. Applicants lacking access to the internet should
contact DWQ's Central Office in Raleigh at [phone].
Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is required for projects occurring in any of North Carolina's twenty-five
counties that contain trout waters. In such cases, the applicant should contact the appropriate NCWRC
regional coordinator (listed by county on page 4 of this application) prior to submittal of the application.
Page 1 of 14
Coastal Area Management Act (CAMA) Coordination - If the project occurs in any of North Carolina's
twenty coastal counties (listed on page 4) the applicant should contact the North Carolina Division of
Coastal Management (DCM). DCM will determine whether or not the project is within a designated
Area of Environmental Concern, in which case DCM will act as the lead permitting agency. In such
cases, DCM will require a CAMA Permit and will coordinate the 404/401 Permits.
The applicant may also choose to coordinate with the United States Fish and Wildlife Service to ensure
that the proposed project will have no impact upon any endangered or threatened species or critical
habitat as regulated by the Endangered Species Act, and the State Historic Preservation Office, North
Carolina Department of Cultural Resources to ensure that the proposed project will have no impact upon
any properties listed or eligible for listing on the National Register of Historic Places. Compliance with
these regulations is required to be eligible for any Department of the Army permit. The addresses for
both agencies are listed on page 3 of this application.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office. Upon receipt of an application, the
USACE will determine if the application is complete as soon as possible, not to exceed 30 days. This
PCN form is designed for the convenience of the applicant to address information needs for all USACE
Nationwide, Regional or General permits, as well as information required for State authorizations,
certifications, and coordination. Fully providing the information requested on this form will result in a
complete application for any of the USACE Nationwide, Regional or General permits. To review the
minimum amount of information that must be provided for a complete PCN for each USACE
Nationwide permit, see Condition 13, 65 Fed. Reg. 12893 (March 9, 2000), available at
http://www.saw.usace.anny.mil/wetlands/nwpfinalFedReg.pdf. Processing times vary by permit and
begin once the application has been determined to be complete. Please contact the appropriate
regulatory field office for specific answers to permit processing periods.
401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated
as optional. Incomplete applications will be returned. Submit seven collated copies of all USACE
Permit materials to the Division of Water Quality, 401/Wetlands Unit, 1650 Mail Service Center,
Raleigh, NC, 27699-1650. If written approval is required or specifically requested for a 401
Certification, then a non-refundable application fee is required. In brief, if project impacts include less
than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to
streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is
required. A check made out to the North Carolina Division of Water Quality, with the specific name of
the project or applicant identified, should be stapled to the front of the application package. For more
information, see the DWQ website at http://h2o.ehnr.state.nc.us/ncwetlands/fees.html. The fee must be
attached with the application unless the applicant is a federal agency in which case the check may be
issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check
so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules,
the application fee does not apply, and the applicant should clearly state (in a cover letter) that only
Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to
issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application
for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the
applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional
requested information, or denial.

Page 9 of 14
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 project layout was specifically designed to avoid and minimize potential impacts to streams and
wetlands as shown on sheet WL-1.0 "Wetland and Surface Water Impact Map ". The roadway crossing
the stream and wetland area is required by the Town of Holly Springs to connect to an existing
subdivision stub street. The roadway was positioned for minimal wetland and stream impact. The
sanitary sewer crossing was also required by the Town of Holly Springs to connect to an adjacent
property and was positioned at a wetland narrow point to minimize impact. The Town of Holly Springs
also required the installation of a erg enway trail, which was located within a proposed sanitary sewer
easement to minimize impacts to wetland areas. The owner will install a raised boardwalk in Impact Area
#5 to join proposed asphalt greenway trail segments that will be installed in upland areas. Out of 15.035
acres of delineated wetlands one the site, the Owners propose to permanently impact only 0.1710 acres
for their benefit. All other impacts are required by the Town of Holly Springs and provide financial
losses instead of gain for the Owners. The proposed permanent lot fill (Impact Area #6) constitutes
approximately 1% of the total delineated wetlands on the property, the majority of which will be
protected in perpetuity if the proposed mitigation plan is accepted. Additional, non-delineated wetland
areas in the Middle Creek flood-plain are not included in these figures, further reducing the percentage of
wetlands impacted. Our calculations using the approved wetland delineation indicate that the
combination CP&L/Gas Line easement consists of 45% jurisdictional wetlands. If this percentage is
assumed to remain consistent through the remainder of the Middle Creek floodplain, approximately 8
acres of additional wetlands exist on the property for a total wetland area of approximately 23 acres. This
estimate reduces the percentage of total wetland area impacted for the owner's benefit to 0.74%.

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
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
htti)://h2o.enr.state.nc.us/ncwetlands/stnngide.html.
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 Owner proposes to mitigate for wetland impacts through the preservation of
jurisdictional wetlands, including streams, beaver ponds, and a man-made pond. Proposed
permanent wetland impacts total 0.4845 acres (includes area of permanent stream impacts).
Per conversations with Mrs. Jennifer Burdette of the Raleigh Regulatory Field Office of the
USACE the required mitigation ratio is 2:1, or 0.9100 acres. Since preservation requires a
10:1 ratio on top of the mitigation ratio, a total of 9.1 acres of wetlands must be protected in
perpetuity to meet these requirements. The proposed preservation plan will protect 6.548
acres of delineated jurisdictional wetlands plus an estimated 6.150 acres of wetlands within
the Middle Creek floodplain that have not been delineated. Where possible, buffers are
included in the proposed conservation areas. As illustrated in the attached Mitigation Plan,
sheet WL-3.0 "Wetland Mitigation/Preservation Plan", the proposed conservation area is
divided into 4 separate tracts in order to exclude existing utility easements. The total wetland
area proposed for protection is 12.698 acres (includes delineated and estimated wetland
areas) for a resultant preservation ratio of 13.95:1.
Page 11 of 14
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at htty://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): none
Amount of buffer mitigation requested (square feet): none
Amount of Riparian wetland mitigation requested (acres): none
Amount of Non-riparian wetland mitigation requested (acres): none
Amount of Coastal wetland mitigation requested (acres): none
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 [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 (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 213 .0233
(Meuse), 15A NCAC 213 .0259 (Tar-Pamlico), 15A NCAC 213 .0250 (Randleman Rules and
)?
Water Supply Buffer Requirements), or other (please identify,
Yes ® No ? If you answered "yes", provide the following information:
Page 12 of 14
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

Mitigation
1 (9,870 Perm) (3,084Temp) 3 none
2 (7,616 Perm) (12,611 Temp) 1.5 none
Total (17,486 Perm) (15,695 Temp) none
* 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 2B .0242 or .0260.
No buffer mitigation is required.
XI. Stormwater (required by DWQ)
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 120.009 acres in area. There are no preexisting impervious surfaces on the site. The
proposed development includes 9.8711 acres of impervious surfaces including roads, sidewalks
and the greenway trail. These surfaces when combined with the future planned recreation center
(0.7074 acres of impervious surfaces) account for less than 9% of the overall site area and
allowing in excess of 5,985 sqft of impervious surfaces per lot (184 lots total) before the 30%
impervious surface threshold is reached. The anticipated impervious surface per lot is less than
2,500 sgft. Level spreaders are supplied at the outlet of all concentrated storm water discharge
points, as required by the Division of Water Quality. Additionally, a bioretention area will
remove 85 percent of TSS from stormwater runoff from impervious surfaces associated with the
recreation area. Detailed plans for the proposed bioretention area are included with this
application package.
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.
The Town of Holly Springs Sanitary Sewer System will collect wastewater generated by this
site and treatment will be provided at the Town of Holly Springs Waste Water Treatment Plant.

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. 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: Express Review Program
Requested Additional Information for the Bridgewater Subdivision
Holly Springs, Wake County, North Carolina
Dear Mr. Dorney,
SEP r 2004
WATER
?4CI1 }??eT/? y
This letter is in response to the request from Ms. Debbie Edwards and Ms. Cynthia Van der Wiele for more
information during our meeting on September 8, 2004, regarding Bridgewater Subdivision in Holly Springs.
Our responses to your requests for additional information are as follows:
I) Level Spreader Details, Cross-Section and Detention
Construction drawing details for the proposed splitter-boxes and level spreaders are attached for your
review. The splitter-boxes will be constructed using the Standard Yard Inlet with Grate and Frame detail
illustrated on Drawing Sheet D-1.0. Level Spreaders will be constructed using the Level Spreader detail
(cross-section included in detail) illustrated on Drawing Sheet D-3.0 and dimensions listed in the Level
Spreaders table on Drawing Sheet C-3.2. The level spreader detail illustrated on Drawing Sheet D-3.0 is
taken from the North Carolina Erosion and Sediment Control Planning and Design Manual. However, the
dimensions of each level spreader are designed according to DWQ guidelines. As discussed in the meeting
mentioned above, the combination of the level spreader and splitter-box will provide stormwater treatment
through detention prior to the treatment provided during the release of diffuse flow through the buffer.
Additionally, as required by the signed and notarized Operations and Maintenance agreement, the level
spreader system will be maintained at least once every six months. Required maintenance includes the
removal of accumulated sediment and debris, maintenance of a level overflow lip and repair of any down
gradient erosion, including replanting vegetation if necessary.
2) Stable Channels for Bypass Flow Through Neuse Buffer
Revised Impact Maps illustrating engineered stable channels for bypass flows through the buffer are
attached for your reference. Also included with the revised Impact Maps are calculations for each bypass
channel. Rip-rap linings and reinforced grassed linings were evaluated for each location. Rip-rap linings
tended to require wider channels than reinforced grassed linings, hence, reinforced grassed linings were
used to minimize impacts to the buffer and wetlands. Additionally, rip-rap lined channels downslope of
FES-4A and FES-20A would constitute additional permanent wetland impacts. All three bypass channels
are designed using North American Green C-350 composite turf reinforcing matting. At installation, with
no vegetation at all, this matting will provide channel protection for stormwater flows in excess of
calculated 10-year peak flows. As vegetation becomes established, the permissible shear stress for each
channel more than doubles in comparison to the permissible shear stress where no vegetation is established.
Manufacturer's information for the proposed C-350 composite turf reinforcing matting is attached for your
reference. Channels will be seeded with an approved wetland seeding mixture.
Phone: [phone] ? Fax: [phone] •972 Trinity Road • Raleigh, North Carolina 27607
On September 9, 2004, I contacted Mrs. Jennifer Burdette with the Raleigh Regulatory Field Office of the
USACE to discuss the proposed bypass channels through buffers and wetlands. Mrs. Burdette asked that S&N
forward the revised Impact Maps to her for review in order to assess the potential for the proposed bypass
channels to drain jurisdictional wetlands. Only two of the three proposed bypass channels (FES-4A and FES-
20A) will be installed through wetlands. All channels are designed to be 1-foot deep, with 2:1 side slopes,
specifically to minimize or eliminate the potential for draining adjacent wetlands. The approval of the wetland
delineation for Bridgewater Subdivision illustrates the existence of soil saturation within 12-inches of the soil
surface, at a minimum. As a worst-case scenario, if the existing soil saturation in the vicinity of the proposed
bypass channels is caused by the water table rising to the soil surface, the channels will lower the water table
immediately adjacent to the channels themselves. However, soil physics research indicates that capillary rise in
coarse silts will rise approximately 10-feet above the water table, well above the 12-inch height of the proposed
channel banks. Hence, the 1-foot deep channels we have proposed for accommodation of bypass flows will in
no way affect the level of saturation of adjacent wetlands. It is more likely that the water table in the vicinity of
the proposed bypass channels is typically below the proposed channel bottom. If this is the case, the water table
will not be lowered at all and the capillary rise that causes the existing saturated conditions within 12-inches of
the soil surface will not be affected either. Essentially, the only way to remove the required soil saturation
within 12-inches of the soil surface is to install a significantly deeper channel with much steeper side slopes. A
much deeper channel with much steeper side slopes would likely cause the loss of soil saturation immediately
adjacent to both sides of the channel, resulting in the effective drainage of the existing wetlands. This scenario
of the deeper channel with steeper side slopes is typical of highly incised natural channels and agricultural
drainage ditches; both of which are very different from what we propose to install at Bridgewater Subdivision.
Thank you in advance for your time spent reviewing this additional information. Do not hesitate to contact me
if you have questions, comments or concerns about this information or other portions of the application.
Sincerely,
Scott Mitchell, PE, LSS

Effective Turf Reinforcement Starts
with Effective Erosion Control
The first word in turf reinforcement mat
(TRM) is "turf', and for good reason.
Without vegetation, the "mat-, has nothing
to reinforce, therefore,
no way to fulfill its
design function. The
relationship between
a TRM and the
l t r- i_
-? vegetation it reinforces
is symbiotic. Meaning
one cannot function
without the other. No matter how
"permanent" the TRM, without
vegetation, the mat will eventuaW
fail. Hence, a TRM's initial
erosion control and vegetation
establishment capabilities
must be considered as
important as its permanent
reinforcement properties.
Introducing North American Green C350
The caveat above forms the basis of North American Green's patented
"Reinforced Composite Mat" technology. Natural fibers are inherently
more effective than synthetic fibers at trapping soil particles and retaining
moisture to enable and enhance vegetation establishment. Yet synthetic
materials are necessary to provide the strength and longevity for long lasting
vegetation reinforcement. North American Green's C350 composite
turf reinforcement matting utilizes both natural and synthetic components
for the ultimate in immediate erosion control and vegetation establishment
as well as permanent vegetation reinforcement.
C350 = Enhanced Temporary Erosion Control
Unlike 100% synthetic TRMs, the C350's permanent structure is incorporated
with natural coconut fibers to enhance the matting's immediate to long-term
erosion control and vegetation establishment capabilities. The coconut fibers
last approximately three years to help absorb the erosive forces of rainfall and
channel flow prior to vegetation establishment, while retaining soil, seed and
moisture to promote vegetation growth. Before vegetation establishment, many
100% synthetic TRMs are prone to floating when submerged, often requiring
manual soil filling and/or increased stapling during installation to maintain
adequate mat-to-soil contact under runoff and channel flow. The C350's
coconut fiber matrix, forming prominent ridges across the width of the mat,
absorbs water and captures sediment in runoff to ensure matting conformance
and adherence with the underlying soil. even when completely submerged. The
result is improved erosion protection for the uninhibited development of
permanently reinforced vegetation.
C350 = Effective Permanent Vegetation Reinforcement
The C350's permanent UV stabilized matting structure consists of a high
strength bottom netting, a super high strength, corrugated middle netting and
a high strength top netting mechanically bonded together to form a three-
dimensional matrix for reinforcing newly developed and fully matured vegetation.
This permanent matting structure boasts significantly higher tensile strengths
and thickness - the two properties considered necessary for turf
reinforcement - than most 100% synthetic TRMs. In fact, no other TRM on the
market has proven greater turf reinforcement capabilities. Furthermore, longevity
studies have shown that the C350's permanent matting structure, even after
almost 5 years of field use, maintains nearly all of its original tensile strength and
thickness. Hence, the C350's unsurpassed vegetation reinforcement capabilities
can be counted on for a long, long time.

Re: Express Review Program
Pre-Construction Notification Application Form for the Bridgewater Subdivision
Holly Springs, Wake County, North Carolina
Dear Mr. Dorney,
Please find attached the completed PCN Application Form, including additional materials required for the
Express Review Program, for the Bridgewater Subdivision in Holly Springs, Wake County. Bridgewater
Subdivision is a proposed residential subdivision owned by Forest Hills Development, LLC. The proposed site
plan and impacts for the property are illustrated in Bridgewater Subdivision - Wetland and Surface Water Impact
Map (WL-1.0) and Bridgewater Subdivision - Neuse River Buffer Impact Map (WL-2.0).
This application describes permanent and temporary impacts to streams, wetlands, and Neuse River buffers.
The impacts are the result of the proposed installation of a road crossing, a sanitary sewer crossing, grading, and
storm drainage. As displayed on WL-1.0, there are seven impact areas for streams and wetlands. WL-2.0 shows
the eight impact areas for Neuse River Buffers. The stream impacts result from the proposed road and sanitary
sewer crossings. The proposed road, storm and sanitary sewer installation/easements, and proposed grading
impact wetland and Neuse River buffer areas.
The proposed impacts for this project have been minimized to the extent of practicality given the requirements
placed upon the design by the Town of Holly Springs. The stream crossings were based upon Town
requirements. Approximately thirty percent of the stream impacts are temporary in nature, while over forty
percent of the wetland impacts and fifty percent of the Neuse River Buffer impacts are temporary.
Additionally, the proposed conservation areas set aside for wetland mitigation are illustrated in Bridgewater
Subdivision - Wetland Mitigation/Preservation Plan (WL-3.0). The areas set aside in the Wetland Mitigation
Plan include 6.548 acres of delineated jurisdictional wetlands, plus an estimated 6.150 acres of wetlands within
the Middle Creek floodplain that have not been delineated. The proposed conservation area is divided into 4
separate tracts in order to exclude existing utility easements.
Thank you in advance for your time spent reviewing this PCN Application. Do not hesitate to contact me if you
have questions, comments or concerns about this application.

VII. Impact Justification (Avoidance and Minimizations
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 project layout was specifically designed to avoid and minimize potential impacts to streams and
wetlands as shown on sheet WL-1.0 "Wetland and Surface Water Impact Man" The roadway crossing
the stream and wetland area is required by the Town of Holly Springs to connect to an existing
subdivision stub street. The roadway was positioned for minimal wetland and stream impact The
sanitary sewer crossing was also required by the Town of Holly Springs to connect to an adjacent
property and was positioned at a wetland narrow point to minimize impact. The Town of Holly Springs
also required the installation of a greenwaa trail, which was located within a proposed sanitary sewer
easement to minimize impacts to wetland areas. The owner will install a raised boardwalk in Impact Area
#5 to join proposed asphalt gr? trail segments that will be installed in upland areas Out of 15.035
acres of delineated wetlands one the site the Owners propose to permanently impact only 0 1710 acres
for their benefit. All other impacts are required by the Town of holly Smogs and provide financial losses
instead of gain for the Owners The proposed permanent lot fill (Impact Area #6) constitutes
approximately J% of the total delineated wetlands on the pLopgjL the majority of which will be
protected in perpetuity if the proposed mitigation plan is accepted. Additional non-delineated wetland
areas in the Middle Creek floodplain are not included in these figures further reducing the percentage of
wetlands impacted. Our calculations using the approved wetland delineation indicate that the
combination CP&L/Gas Line easement consists of 45% jurisdictional wetlands If this percentage is
assumed to remain consistent through the remainder of the Middle Creek floodplain, approximatel 8
acres of additional wetlands exist on the property for a total wetland area of approximately 23 acres This
estimate reduces the percentage of total wetland area impacted for the owners benefit to 0.74%.

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
f
reshwater 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
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/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
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The Owner proposes to mitigate for wetland impacts through the preservation of
jurisdictional wetlands including streams beaver ponds and a man-made pond Proposed
permanent wetland impacts total 0.4845 acres (includes area of permanent stream impacts.
Per conversations with Mrs. Jennifer Burdette of the Raleigh Re latory Field Office of the
USAGE, the required mitigation ratio is 2:1 or 0.9100 acres Since preservation rewires a
10:1 ratio on top of the mitigation ratio, a total of 91 acres of wetlands must be protected in
perpetuity to meet these requirements. The proposed preservation plan will protect 6.548
acres of delineated jurisdictional wetlands plus an estimated 6.150 acres of wetlands within
the Middle Creek floodplain that have not been delineated Where possible buffers are
included in the proposed conservation areas. As illustrated in the attached Mitigation Plan,
sheet WL-3.0 "Wetland Miti ation/Preservation Plan" the proposed conservation area is
divided into 4 separate tracts in order to exclude existing utility easements The total wetland
area proposed for protection is 12.698 acres (includes delineated and estimated wetland
areas) for a resultant preservation ratio of 13.95:1.

jurisdictional and non jurisdictional wetland, stream, water features, and State
regulated buffers must be underlain on the site plan(s). The plans must show all
built-out structures and impervious cover. The plans must include the final grading
contours with elevations. The plans must indicate all utilities and easements. It is
likely that several versions of the final built-out site plans will be necessary. The
following is a list of layers:
? Drainage Plans - Final drainage plans must be included. The plans should include
the locations and pertinent elevations and sizes of the collection system and
drainage ways. All inlets and outlets must also be shown with pertinent elevations.
Scaled stormwater BMPs must also be indicated as required by DWQ rules and
policies. In certain cases, final stormwater management plans must also be
provided, but that will be addressed later in this document.
? Plats - The plans must show the location and layout of all sub-divided parcels with
lot identifications. Platted parcels must be developable without further impacts to
jurisdictional and non jurisdictional wetlands, streams, water features, and State
regulated buffers.
? Proposed Impacts - All impacts to jurisdictional and non jurisdictional wetland,
stream, water features, and State regulated buffers must be shown and labeled on
the site plans. All excavation, fill, flooding, stabilization, and other impacts that will
be conducted in or near jurisdictional and non jurisdictional wetland, stream, water
features, and State regulated buffers must be indicated.

? Roadway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
N/A When surface drainage features or groundwater recharge areas that feed or would
reasonably feed wetlands that are not to be filled are made impervious, it may be
necessary to direct some stormwater runoff to those areas in order to maintain hydrology.
You must identify these areas and address them. Supporting explanations and discharge
information must be provided to show that the wetland would not be eroded or receive
too much or too little hydrology. In many cases this could help satisfy part of a
stormwater management plan.
The proposed impacts will not affect wetland or recharge area water supplies.
N/A Flooding
The proposed wetland impacts are not located in the FEMA 100-YR Floodplain.
N/A Draining
There is no wetland draining associated with the project.
Stream Impacts:
? Stream impacts must be clearly shown on the plans. The centerline as well as the banks
of the stream must be surveyed or located by GPS for the portion of the stream to be
impacted.
Culverting:
? The inlet and the outlet of the culvert should be aligned with the stream as much as
possible. Inlet and outlet elevations and stream bed elevations should be indicated.
N/A Any widening of the stream must be shown with elevations.
There is no proposed stream widening associated with the project.
? The extent of and plan details for all dissipation or grade control devices should be shown
with pertinent elevations.
The elevation of energy dissipation devices matches that of their associated flared
end section.

shows the minimum distance from each span to each stream bank, the stream cross
section, the height of the span above the stream and the minimum distance from the
edge of each footer to each stream bank.
There are no bottomless culverts or other spans associated with this project.
N/A For bottomless culverts or other spans, a plan view must be provided that shows the
location of the spans and the stream banks.
There are no bottomless culverts or other spans associated with this project.
WA For longer culverts or culverts that will pass beneath substantial impervious cover, it will
be necessary to provide adequate plan detail to show that discharge velocity/energy will
be adequately dissipated.
There are no longer culverts associated with this project.
? Aquatic life passage through culverts is typically achieved by placing the invert of the
culvert below the existing bed of the stream per the USACE or North Carolina Wildlife
Resource Commission guidelines. Other methods such as baffles may also be used.
Please be aware that such placement may require the use of grade/velocity control
measures up or down stream of culverts on steeper streams to prevent head-cuts or
stream bed erosion. The culvert placement relative to the stream bed can be indicated
on the longitudinal profile. Grade and velocity control measures must be indicated on the
plan view and typical designs should be provided.
? Multiple culverts, wide culverts or sectioned box culverts typically require the use of sills,
off-setting or other means to match the cross section of the existing stream (in order to
maintain stream stability and provide aquatic life passage). A vertical cross section of the
culverts should be shown overlain with the up and downstream stream cross section
including the stream flood-prone area.
N/A Impacts associated with dam construction must indicate and enumerate all fill associated
with the dam foot print, spillway and any bank stream bank stabilization. The length of
stream impounded must also be indicated and enumerated.
There is no dam construction associated with this project.
Stream Relocations:
N/A - There are no proposed stream relocations associated with this project.
? Stream relocations must be conducted as specified in General Certification numbers
3402 and 3404 (avgjlgpl? ran the Wetlands Unit web site). Stream relocation plans must
include:
? Morphological measurements (see Appendix B of the Internal Technical Guide for Stream
Work in North Carolina available on the Wetlands Unit web site) - not all of the
measurements are applicable in every instance.
6
? Typical stream cross sections - Typically, a riffle cross section and a pool cross section
that includes the entire flood prone area. The bankfull and flood prove area elevations
should be indicated. Similarly, a riffle cross section of the reference stream(s) should be
provided.
? Plan view - Provide scaled plans that show the location of the proposed (preferably with
stationing) and the existing stream. In most instances, the bankfull contours and flood
prone area contours, in stream structures, bank revetments/stabilization, channel plugs,
planting plan, vegetation conditions, stormwater outlets, grade controls, bridges, culverts,
sewer lines, roads, fencing, and easement lines should also be provided.
? Longitudinal Stream Profile -A scaled profile that indicates the thalweg, bankfull, and top
of bank elevations should be provided for the design and reference streams. In many
cases, it will also be necessary to show the existing land elevations for the design
stream.
? Planting Plan - A planting and/or vegetation management plan should also be provided
that makes use of appropriate native vegetation. The plan should indicate the extent,
density, and species of plants to be provided.
? In-stream structure, bank revetmentlstabilization, and stormwater outlet typicals -
Detailed, typical plans should be provided for all in stream structures, bank revetments or
stabilization, and stormwater outlets. The typicals should include materials and
specifications as well as relative lengths, positions, and angles.
? Sediment transport analysis - A sediment transport analysis should be provided based
on the current, relevant, accepted practices. The sediment transport analysis should be
relevant to the stream bed load type and should predict bed load transport equilibrium.
? Permanent conservation easement or similar means of protection must also be provided.
Other Information:
? 1. The project should always be referred to by this name in all correspondence as well
as the DWQ # once it is provided.
? 2. This only applies to DOT projects, which are not expected to utilize the Express
Review Program.
? 3. This should be the size of the project as identified by the USACE for 404 Permits or
by the Division of Water Quality for Buffer Approvals and Isolated Wetland Permits.
? 4. Please provide the name (as depicted on the USGS topographic map and DWQ
Stream Classification Lists) of the nearest water body(ies) to which your project is a
tributary to (e.g. "Neuse River (Falls Lake below normal pool elevation)"). (Do not
simple state "stream", "river", "ocean", "sound" or "lake".) Please provide the "stream
index number" of the named water body or water body section (e.g. "27-(1)"). Also,
please provide the full water quality classification (e.g. "WS-IV NSW CA") of the water
body. This information can be obtained from the DWQ web site
http://h2o. enr. state. nc. us/bims/Reports/reportsWB. html.
? 5. Please state which river basin and sub-basin that your project is in (e.g. "Neuse River
Basin, NEU01"). This information can be obtained from the DWQ web site
http://h2o.enr.state. nc. ustbims/ReportstreportsWB.htmi.
? 6. Conditions should also be indicated on the existing site plan where applicable.
Photos (including aerial photos) can be helpful in describing the existing conditions.
? 7. You must provide an attachment that explicitly describes what the proposed project
will entail from the planning stage to final construction.
? 8. This can be a simple explanation, but it is critically important because the purpose
dictates how the no practical alternatives are reviewed.
SECTION IV - PRIOR PROJECT HISTORY
? Please include copies of all 401 Water Quality Certifications, Isolated Weiland
Permits, Buffer Approvals, USACE Permits, CAMA Permits for the site as well as a
copy of the final approved, site plan.
SECTION V - FUTURE PROJECT PLANS
? For projects utilizing the express review process, all impacts both present and
potential future must be indicated. For instance, the location or configuration of
platted lots sometimes suggests that future impacts will be necessary to build,
access, or otherwise develop such lots. Failure to account for such potential impacts
could delay or disqualify a project from the rapid review process. If you believe that
the lot can be developed without impacts, but you anticipate that your assertion may
be questioned, it is recommended that you provide a potential building foot print
and/or grading plan to show that future impacts could be avoided.
SECTION VI - PROPOSED IMPACTS TO WATER OF THE US
? 1. It is recommended that the individual impacts be described if there are special things
to note about the impacts. Typically the most important thing is to have detailed
accurate site plans as described above. Please make sure they are clearly labeled.
? Please include all proposed temporary impacts.
? Also, a current, signed delineation map from the USACE should be provided (if
available) and a map locating the stream origins signed by the appropriate DWQ
Staff must be provided if applicable.
0 2. Each impact to a wetland must be clearly labeled and identified on the site plan. The
type of impact must be clearly stated. If the impact is temporary, a specific plan must
be described or shown as to how the wetland will be restored. Keep in mind that the
USACE delineates some features as wetlands that DWQ calls streams. Please do
not list any impacts in this table that DWQ would identify as a stream. If there is any
doubt, it is recommended that the impacts be listed as streams.
? 3. Each impact to a wetland must be clearly labeled and identified on the site plan. The
type of impact must be clearly stated. If the impact is temporary, a specific plan must
be described or shown as to how the wetland will be restored. Keep in mind that the
USACE delineates some features as wetlands that DWQ calls streams. Please list
any impacts in this table that DWQ would identify as a stream. If there is any doubt,
it is recommended that the impacts be listed as streams. Please follow current DWQ
policy with respect to whether a stream is perennial or not. It is recommended that
you assume that a stream is perennial (unless you are positive that it is not) so if
mitigation is required then the appropriate amount of mitigation would be anticipated
or requested from the WRP or private bank. If the WRP or private bank has pre-
approved too short of an amount of stream or if inadequate mitigation is proposed,
then that situation will result in delays.
? 4. Sometimes it is difficult to determine whether a feature is a modified natural channel
or a ditch, especially in the eastern part of the State. Soils, drainage features,
topography, and similar factors, all are important for making that determination.
N/A 5. Other items to address not specifically requested in the application include
downstream sediment starvation, thermal pollution, low flow releases from dams, and
aquatic life passage. Other important considerations are buffer reestablishment or
8
mitigation around ponds on buffered streams. The site plan should include the
precise elevation contour of the normal pool as well as the dam foot-print. Mitigation
is required for wetland flooding of an acre.or greater and for stream fill (if over the
• 150 foot threshold) under the dam foot-print and any outiet stabilization.
There is no pond creation associated with this project.
SECTION VI -AVOIDANCE AND MINIMIZATION
Avoidance and minimization are critical aspects of an application particularly if you desire the application
to be processed expeditiously. The following is a check-list of avoidance and minimization questions that
DWQ Staff often look for in applications. .
? Are there any stream crossings at angles less than 75° or greater than 105°?
Yes. The proposed stream crossing is required by the Town of Holly Springs. The
stream must be crossed at a slight angle in order to meet street specifications,
provide connectivity to the adjacent property, and cross the stream at a location with
minimal impacts to streams and wetlands.
0 Are there any stream crossings that cross two streams above or at the confluence of those
streams?
No.
? Are there any stream, wetland, water, and/or buffer impacts other than perpendicular road
crossing near the edges of the property?
No.
? Can the stream be relocated as a natural channel design as opposed to culverted or
otherwise filled?
No.
? Is any single stream crossed more than once?
No.
? Can property access routes be moved or reduced to avoid stream, wetland, water, and
buffer impacts?
No.
? Can a building, parking lot, etc. be realigned to avoid impacts?
No.
? Can the site layout be reconfigured to avoid impacts?
No.
0 Can headwalls or steeper side slopes be used to avoid/minimize impacts?
Headwalls are being used to minimize impacts.
? Can a retaining wall be used to avoid/minimize impacts?
No.
9
? Can cul de sacs be used in place of a crossing?
No.
? Can lots be reshaped or have shared driveways to avoid impacts?
No.
If based solely on the practicable physical possibility, the answer is "yes" to any of the above questions
then you must have to provide substantial and convincing justification as to why the impacts are
necessary. If the impacts are required by a local government or other agency the claim must be
supported with appropriate written documentation from the local government or other agency. Most
projects typically involve the need to justify avoidance and minimization. If this information is not readily
available, then the express review process may not be the appropriate venue to use because the project
may be put on hold at the end of the process. Providing alternative plans (such as plans that avoid the
impact, minimize the impact and the preferred plan, similar those used in environmental assessments)
and explanations as to why the preferred plan is needed and why the alternative plans won't work are
many times helpful in the no practical alternatives review.
SECTION VIII - MITIGATION
NIA - Mitigation is not necessary for the proposed impacts.
Mitigation for the Express Review Program, final mitigation plans must be presented up front. The final
plans (except for plans that propose payment into the Wetlands Restoration Fund, Riparian Buffer
Restoration Fund, private mitigation banks, or similar banking instruments) must contain detailed plans,
specifications, calculations and other supporting data that show that the appropriate mitigation will be
achieved at the ratios required. The design plans must be developed to at least the °90%" level.
Monitoring plans must be final and specific. Any means of permanent protection, such as a permanent
conservation easement must be provided. If you elect to use the WRP or a private mitigation bank, it is
recommended that you request the maximum possible mitigation amount that DWQ may require so that
you will not have to get further approval from them on short notice. The WRP and private banks are not
part of the expedited review process and cannot be expected to meet any such deadlines. There will be
no conditional expedited approvals that require final plans at a later date. It is not recommended that
innovative mitigation techniques or greater than 10% preservation be requested as part of an expedited
process.
SECTION IX
NIA - NEPA/SEPA documentation is not required for the proposed impacts
If your project requires the preparation of an environmental document under NEPA or SEPA and an
approval letter has not been issued by the State Clearinghouse, then you cannot apply under the
expedited review process. I t is your responsibility to find out if such documentation is required.
SECTION X
There are many aspects of the Buffer Rules that must be addressed in every application, if applicable.
The first and most important thing to keep in mind is that allowable activities that require written Approval
from DWQ triggers a review of the entire project for compliance with the Buffer Rules.
Diffuse Flow & Stormwater Management:
? The most common issues that arise involve the requirement for diffuse flow of stormwater
through riparian buffers. Basically one of three things must be indicated in regards to all
"new" stormwater that is collected and subsequently discharged. First, provisions for
diffuse flow through the protected buffer must be made. This usually involves the use of
level spreading devices designed to the latest DWQ guidance on level spreader design,
which is available on our web site. Please keep in mind that it does not matter how far a
discharge point is from a buffer. The stormwater must be flowing in a diffuse manner at
10
whatever point it eventually reaches the buffer. If the stormwater will not be flowing in a
diffuse manner through the protected buffer at the point it reaches the buffer, then one of
the following options maybe allowed:
? You may provide a nitrogen removing measure such as a forested filter strip,
grassed swale, stormwater ,t+etland, etc. The measure employed should be
designed according to the NC DENR Stormwater Best Management Practices
Manual or other DWQ Guidance available at http:
//h2o.ehnr.state.nc.ustncwetlands/mitresto.html. After the nitrogen is treated; the
stormwater can be directly conveyed through the buffer with written DWQ approval.
? You may discharge the stormwater to an existing man-made conveyance that
currently conveys stormwater through the protected buffer (assuming the
conveyance was not constructed in violation of the Rules) as long as that
conveyance does not need to be altered to convey the flow. Please remember that
there are no other choices. The following checklist is intended to help insure that
your application will not be deemed incomplete as a result of improper stormwater
design.
Stormwater Management (for Buffer Rules compliance only - Also, see Section XI):
* Worksheets located in Appendix F
? All stormwater out-falls must be clearly shown and labeled on the site plan for projects in
Buffered watersheds. List each out fall as labeled: FES-4B. FES-2013. FES-6013. FES-86.
FES-104
? Option 1: Level spreading devices designed to the latest DWQ Guidance, and
devices that merely control velocity but do not provide diffuse flow such as rip rap
dissipators are not proposed. List each of these out-falls as labeled on the site
plan and provide a DWQ worksheet available at
http://h2o.ehnr.state.nc.us/ncwetlands/mitresto.html: FES-413. FES-20B. FES-606.
FES-86. FES-104
N/A Option 2: Nitrogen removing measures designed to DWQ Standards are
proposed for discharges for which diffuse flow through a protected Buffer cannot be
met. List each of these out-falls as labeled on the site plan and provide a DWQ
worksheet available at http://h2o.ehnr.state.nc.ustncwetlandstmitresto.html:
N/A Option 3: The stormwater will be discharged to an existing man-made (not
including modified natural channels) conveyance that carries the stormwater
through the Buffer. The conveyance was not constructed in violation of the Buffer
Rules. List each out-fall as labeled:
? All stormwater out-fall must meet one of the options above. (Note: if you cannot check this
box your application will likely not be accepted into the express review process.)
Site Plans:
? All applications on properties with DWQ protected buffers must clearly depict the buffers
and any impacts to the buffers on the site plans. The impact maps should clearly depict
both zones of the protected buffers and the proposed impact areas (provided in square
feet).
Surface Water & Buffer Delineations:
? Any surface waters subject to DWQ protected buffers must be field located and accurately
depicted on the site plans and impact maps. The width, dimensions and pattern of the
surface water must be delineated. The surface water location must not be taken simply
11
from a USGS map, soil survey or local municipality's map. The buffers must be measured
from the surface water as required within the applicable buffer protection rule (e.g., all
buffers along streams subject to the Neuse Buffer Rule must be measured from the "top-of-
bank" of the stream and not the centerline of the stream). All streams must be surveyed or
located by GPS and shown precisely on the site plans.
Impact Table:
Please provide additional impact tables that clearly state the area of impact for each
corresponding impact site.
Variances:
NIA - no variances are required for the proposed impacts.
? Projects that require the Minor and "General" Variances may be eligible for the use of the
Express Review Program. However, Major Variances are not eligible. If your project
requires a Minor or "General" Variance approval, then be sure to attach a completed Minor
or "General" Variance application.
Mitigation:
NIA - no mitigation is required for the proposed impacts.
? As opposed to applications that are submitted under our regular process, final mitigation
plans must be presented up front (see requirements for Section VIII above). The mitigation
plans must comply with the applicable buffer mitigation rule.
SECTION XI - STORMWATER
Please provide the following information in regards to potential stormwater requirements:
? The total acreage of the site. 120.009 (acres)
? The total built-out impervious acreage 21.14 (acres)
*assuming 2500 SQ FT impervious area per lot
? The total area that will be disturbed 60.13 (acres)
NIA If the total area exceeds 20% imperviousness, the development on the site is uniform in
density, and you are claim that the total impervious area is less than 30%, you must
provide a complete, detailed breakdown of the assumed built-out conditions. The
breakdown must be detailed enough to show that all potential impervious areas are
accounted for.
Total impervious area <20%
? If there are concentrated areas of development such as multi-family, commercial, cluster,
club houses, etc. that exceed 30% imperviousness and the total imperviousness for the site
does not exceed 30%, a stormwater management plan will likely be required for those
areas that exceed 30% imperviousness.
? Stormwater management plans must be complete with a final design and an executed
Operation and Maintenance Agreement. There will be no conditional stormwater approvals
for the express review process that allow for approval of the final plans at a later date.
Worksheets must be provided that are available at
http://h2o.ehnr.state. nc. ustncwetiandstmitresto. htmi.

SECTION XII - SEWAGE DISPOSAL
? Response must be clear and detailed. Any disposal method that suggests further impacts
may be required other than those shown must be clearly addressed on the site plans.
SECTION XIII
? Answering yes to either of these responses automatically preciudes you from the express
review process.
SECTION XIV - SIGNATURE
? The name, position and/or title of the applicant must be in type or long hand script here with
the signature. It should be the same person as described in Part II.
When applying to use a General Certification it is important to review every condition of the Certification
to determine whether or not your project can and will meet all of the conditions. For each Certification for
which you have applied, you must list the number of each condition and specifically where the information
is provided in the application or how and why the condition will or will not be met if not otherwise
described in the application. The following format is provided for GC 3402 as an example:
NIA GC 3402 for Nationwide Permit
NIA - as per conversation with Debbie Edwards.
Remember, N/A by itself is not an acceptable answer. You must explain why you think something does
not apply.
If you have any questions about these requirements, please email the Express Review Program at
[e-mail] and include your question and phone number and the appropriate staff will
- respond as soon as possible.

Subject: Neuse River Basin Buffer Rules
NBRRO 03-290
Bridgewater Site
Holly Springs, Wake County, NC
Dear Mr. Conoly:
On September 8, 2003, 1 conducted a site visit of feature A involved in the above referenced
project as identified on the attached maps. It was determined that the feature shown on the Wake
County Soil Survey, but absent on the USGS Apex, 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: 02B.0233
(NCAC.0233).
The Division of Water Quality (DWQ) has determined that the surface water labeled
as " A " on the attached maps is not subject to the Neuse Buffer Rule. (All other features
within these property boundaries were not evaluated, therefore they are determined as
subject to the Neuse Buffer Rule.) This feature and it's associated buffers should be identified
on any future plans for this property. The owner (or future owners) should notify the DWQ (and
other relevant agencies) of this decision in any future correspondences concerning this property.
This on-site determination shall expire five (5) years from the date of this letter.
Landowners or affected parties that dispute a determination made by the DWQ or Delegated
Local Authority that a surface water exists and that it is subject to the buffer rule may request a
determination by the Director. A request for a determination by the Director shall be referred to the
Director in writing, c/o John Dorney, DWQ Wetlands/401 Unit, 2321 Crabtree Blvd., Raleigh, NC
27604-2260.
Individuals that dispute a determination by the DWQ or Delegated Local Authority that
"exempts" a surface water from the buffer rule may ask for an adjudicatory hearing. You must act
within sixty (60) days of the date that you receive this letter. Applicants are hereby notified that the
sixty (60) day statutory appeal time does not start until the affected party (including downstream and
adjacent landowners) is notified of this decision. DWQ recommends that the applicant conducts

this notification in order to be certain that third party appeals are made in a timely manner. 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, P.O. Box 27447, Raleigh, N.C. 27611-7447. This
determination is final and binding unless you ask for a hearing within sixty (60) days.
This letter only addresses the applicability of the Neuse Buffer Rules. For information
relevant to 401 Water Quality Certifications, wetlands and other impacts to "waters of the state",

MEMORANDUM
TO: John Dorney, Wetland Scientist
Wetlands/401 Water Quality Certification Unit
Division of Water Quality
FROM: Shari L. Bryant, Piedmont Region Coordinator
Habitat Conservation Program
DATE: 13 September 2004
SUBJECT: Pre-construction Notification Application for Bridgewater Subdivision, Wake County,
North Carolina. DWQ ID: 041251
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the
subject document and we are familiar with the habitat values of the area. Our comments are provided in
accordance with provisions of the Clean Water Act of 1977 (as amended), the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), North Carolina General Statutes (G.S.
113-131 et seq.).
The applicant proposes to impact 155 linear feet (If) of perennial stream channel (110 if
permanent and 45 if temporary), and 0.7868 acres of wetlands (0.4592 acres permanent and 0.3276 acres
temporary) in the Neuse River watershed for infrastructure and lot fill to support a single-family home
subdivision. Total impervious surface is expected to be less than 30%. Level spreaders are proposed to
be installed at all concentrated stormwater discharge points. A bioretention area will be installed to filter
stormwater runoff associated with the recreation area.
The proposed project will impact an unnamed tributary to Middle Creek in the Neuse River basin.
There are records for the state threatened Eastern tiger salamander (Ambystoma tigrinum), triangle floater
(Alasmidonta undulata), Eastern lampmussel (Lampsilis radiata radiata), Roanoke slabshell (Elliptio
roanokensis), creeper (Strophitus undulatus), and least brook lamprey (Lampetra aepyptera); and the state
special concern Neuse River waterdog (Necturus lewisi) and North Carolina spiny crayfish (Orconectes
carolinensis) in Middle Creek.
We question the need to permanently impact 0.1827 acres and to temporarily impact 0.0761 acres
of the wetlands identified as Impact Area #6 (lot grading and erosion control) and Impact Area #7 (storm

drainage and easement). The PCN indicates that these are forested wetlands and according to the maps
provided these wetlands appear to be adjacent to an unnamed tributary to Middle Creek. We hesitate to
concur with the filling of wetlands due to their wildlife habitat value and the well-known beneficial
functions that they provide for flood control and water quality protection. We recommend that the
applicant avoid impacting these wetland areas (lots 168 and 169) and suggest that these wetlands be
dedicated as open space.
We further recommend that the following conditions be incorporated into the permit to reduce
impacts to aquatic and terrestrial wildlife resources.
1. We recommend that remaining wetlands and streams on the site be protected from additional
impacts by placing them in a permanent conservation easement, and by recording preserved areas
on deeds. We recommend that these areas are preserved in perpetuity via donation of the
easement to a land trust or similar entity and that property owners be informed of preservation
status.
2. In order to minimize stream impacts, while retaining some measure of wildlife habitat, we
recommend a 100-foot undisturbed, native, forested buffer along perennial streams, and a 50-foot
buffer along intermittent streams and wetlands. Maintaining undisturbed, forested buffers along
these areas will minimize impacts to fish and wildlife resources, water quality, aquatic habitat
both within and downstream of the project area, and help prevent the extirpation of endangered
and threatened species. In addition, wide riparian buffers are helpful in maintaining stability of
stream banks and for treatment of pollutants associated with urban stormwater. Whereas, a
grassed buffer, particularly fescue, is a vegetated buffer but will not provide the necessary and
highly valuable functions as discussed for forested buffers.
If culverts must be used, the culvert should be designed to allow passage of aquatic organisms.
Generally, this means that the culvert or pipe invert is buried at least one foot below the natural
streambed. If multiple cells are required, the second and/or third cells should be placed so that
their bottoms are at stream bankfull stage. This will allow sufficient water depth in the culvert or
pipe during normal flows to accommodate movements of aquatic organisms. If culverts are long
and sufficient slope exists, baffle systems are recommended to trap gravel and provide resting
areas for fish and other aquatic organisms. If multiple pipes or cells are used, at least one pipe or
box should be designed to remain dry during normal flows to allow for wildlife passage. In
addition, culverts or pipes should be situated so that no channel realignment or widening is
required. Widening of the stream channel at the inlet or outlet of structures usually causes a
decrease in water velocity causing sediment deposition that will require future maintenance.
Finally, riprap should not be placed on the streambed.
4. Concrete is toxic to aquatic life and should not be allowed to come in contact with surface waters
until cured.
5. The construction of roadways in new neighborhoods can produce short-term direct impacts as
well as long-term cumulative effects. Studies have shown a serious decline in the health of
receiving waters when 10-15% of a watershed is converted to impervious surfaces (Schueler
1994). To adequately protect streams, it is suggested that impervious surface is limited to less
than 10%. Alternatively, provide for sufficient open space to effectively reduce impervious
surface so that predevelopment hydrographic conditions are maintained. To achieve no net
change in the hydrology of the watershed, we recommend installation of grassed swales in place
of curb and gutter and on-site stormwater management (i.e., bioretention areas). Information on

innovative stormwater and low impact design (LID) ideas may be obtained at
www.lowimpactdevelopment.org (accessed September 2004).
6. We recommend that landscaping consist of non-invasive native species and LID technology.
Using native species instead of ornamentals should provide benefits by reducing the need for
fertilizers, herbicides, and pesticides. Additionally, native species should require less water.
Using LID technology in landscaping will not only help maintain the predevelopment hydrologic
regime, but also enhance the aesthetic and habitat value of the site.
7. We advise that specialized efforts and techniques be implemented to reduce sediment runoff from
construction activities and that the Neuse River buffer rules be strictly adhered to
Thank you for the opportunity to provide input during the planning stages for this project. If we
can be of further assistance, please contact our office at [phone].

Re: Express Review Program
Requested Additional Information for the Bridgewater Subdivision
Holly Springs, Wake County, North Carolina
Dear Mr. Dorney,
WETLANDS 1401 CROUP
SEP 0 1 2004
WATER QUALITY SE DON
This letter is in response to your request for more information dated August 27, 2004, regarding Bridgewater Subdivision in
Holly Springs. Our responses to your requests for additional information are as follows:
I) Level Spreader Using Bypass Method
Plan details and calculations sufficient for the proper construction of each level spreader are illustrated on the storm
drainage plans and schedules that were included in the original application package.
While the "splitter-box" bypass method we have proposed for level spreaders FES-4B, FES-20B and FES-60B does
not appear verbatim in the Draft Level Spreader Design Options, Version 1. 0, it does satisfy the purpose, spirit and
intent of the riparian buffer protection program. The Draft Level Spreader Design Options, Version 1.0 states that
"there are alternative designs, like the ones listed below, that would allow a level spreader to function properly by
bypassing the larger discharge events. This is based on the assumption used in designing most water quality BMPs
that the `first flush' of stormwater discharge contains the most substances of concern." According to the North
Carolina Erosion and Sediment Control Planning and Design Manual, a type B silt basin has a trapping efficiency
greater than 75 percent for most sediment in the Coastal Plain and Piedmont regions. When added to the TSS removal
provided by the level spreader and buffer, requiring a silt basin preceding the level spreader is equivalent to requiring
greater than 85 percent TSS removal for the contributing area. The splitter-box bypass method clearly provides
treatment for the "first flush" while allowing larger events to bypass the level spreader. Additionally, your office has
regularly approved this bypass method in the recent past.
2) Wetland Impacts, Storm Drainage and Easement (permanent wetland impacts)
The bypass flow outlet has been reconfigured to eliminate permanent storm drainage and easement wetland impacts at
this location.
3) Riparian Buffer Impacts:
a) Impact Area #4, Storm Drainage and Easement (permanent buffer impacts to Zone 2)
The bypass flow outlet has, been reconfigured to eliminate permanent storm drainage and easement Neuse Buffer
impacts at this location. Permanent impacts to Zone 2 of the Neuse Buffer for the level spreader maintenance
easement remain. This easement is required for the perpetual maintenance of the level spreader and will be
maintained in an herbaceous state with no impervious surfaces introduced in this area.
b) Impact Area #7, Erosion Control (temporary buffer impacts to Zone])
The proposed 93.21 R2 of temporary Zone I Neuse Buffer impacts have been removed.
c) Impact Area #8, Storm Drainage and Easement (permanent buffer impacts to Zone 2)
Permanent Neuse Buffer Zone 2 impacts for this area are for storm drainage and level spreader maintenance
easements. These easements are required for the perpetual maintenance of the level spreader and storm drainage

system and will be maintained in an herbaceous state with no impervious surfaces introduced in these areas.
d) Impact Areas O, 2,3,4,5,6, 7, and 8 have proposed "temporary" buffer impacts to Zone 2 Please explain the
difference in "temporary" versus "permanent" impacts to Zone 2.
Spaulding & Norris typically includes temporary impacts for jurisdictional areas that will likely incur minor
impacts during construction. Minor impacts include Neuse Buffer disturbance such as incidental soil or vegetation
disturbance that is unavoidable during construction while using heavy equipment such as track-hoe excavators,
bulldozers, etc. This type of impact is not intended to be permanent, hence S&N presents these impacts as
temporary. Temporary impact areas are seeded with approved native herbaceous vegetation if soil disturbance
warrants and allowed to naturally return to a forested state.
4) Stream Impacts.
Spaulding & Norris typically includes temporary impacts for jurisdictional areas that will likely incur minor impacts
during construction. Minor impacts include stream bank disturbance such as incidental soil, bank or vegetation
disturbance that is unavoidable during the construction of road crossings while using heavy equipment such as track-
hoe excavators. This type of impact is not intended to be permanent, hence S&N presents these impacts as temporary.
Temporary impact areas are seeded with approved native herbaceous vegetation if soil disturbance warrants and
allowed to naturally return to a forested state.
Thank you in advance for your time spent reviewing this additional information. Do not hesitate to contact me if you have

REQUEST FOR MORE INFORMATION-EXPRESS REVIEW PROGRAM
Dear Sir or Madam:
On August 19, 2004, the Division of Water Quality (DWQ) received your application dated August 19,
2004 to impact 0.7868 acres of wetlands, 155 feet of stream and 32,729 square feet (ft2) of protected
riparian buffers to construct the proposed Bridgewater Subdivision. On August 23, 2004, the DWQ
received the additional information requested in the "Request For More Information" letter sent on August
20, 2004. The DWQ has determined that your application was incomplete and/or provided inaccurate
information as discussed below. The DWQ will require additional information in order to process your
application to impact protected wetland, streams and/or buffers on the subject property. Therefore,
unless we receive the additional information requested below, we will have to move toward denial of your
application as required by 15A NCAC 2H .0506 and 2B .0233(8) and will place this project on hold as
incomplete until we receive this additional information. Please provide the following information so that
we may continue to review your project.
Additional Information:
1. Level Spreader using bypass method:
You are proposing to use the bypass method for level spreaders FES-413, FES-20B, and FES-60B.
Under the Required Items Checklist (on the Level Spreader Worksheet), you initialed that the bypass
method and plan details and calculations are provided. This was not included in the package submitted
to the DWQ Express Review Program.

Requested Additional Information for the Bridgewater Subdivision srA? 2004
Holly Springs, Wake County, North Carolina s!'
R Q(/?17YS?C?
Dear Mr. Dorney, QN
This letter is in response to your request for more information dated August 20, 2004, regarding Bridgewater Subdivision in
Holly Springs. Our responses to your requests for additional information is as follows:
Please submit three (3) fuU sized plans (to scale) of the following: drawings sheets, WL-1.0, WL-2.0, WL-3.0, C-3.0,
C-3.1 and C-16.0.
Three sets of the requested full size plans are attached for your review.
2. Please clarify what bypass method is to be used on level spreaders, FES 4B, FES 20B and FES 60B? Also, please
make sure all level spreaders are located within drainage easements for future maintenance.
FES 4B, FES 20B and FES 60B all utilize what we call a "sputter-box" bypass. The sputter-box replaces the typical
single flared end section outlet with a junction box that separates the flow from the 1-inch per hour storm from the flow
of more intense rainfall events. The splitter-box is constructed with two separate outlet pipes with different invert
elevations. The lowest invert receives all runoff from the 1-inch per hour intensity storm. This flow is directed to the
level spreader. Once a storm's intensity becomes greater than 1-inch per hour, the additional flow is directed to the
second outlet. The second outlet discharges to a typical rip-rap dissipator pad. Stormwater that is discharged through
the second outlet is allowed to pass through the buffer as concentrated flow. This bypass method utilizes the buffer
itself as a forested filter strip to treat the "first flush" of stormwater discharge. Outlet inverts are set by calculating the
hydraulic grade line (HGL) for the 1-inch per hour storm event. S&N uses the software package Hydraflow Storm
Sewers 2000 to calculate HGLs.
3. Please submit an Operations and Maintenance Agreement for your level spreaders and Bioretendon Area, an
example of this information can be found on our 4011Wedands Unit website. htty://h2o.enr.state.ne.uslncwetiands.
Operations and Maintenance agreements for level spreaders and the Bioretention Area are attached for your review.
4. On your Bioretendon Area Worksheet it was indicated that the inlet velocities are assumed to be less than 1.0 fps.
Please note that the inlet velocity must not exceed 0.67fps.
Detailed calculations for Bioretention Area inlet velocity are attached for your review. Our calculations indicate an
inlet velocity of 0.7122 fps. The velocity calculated is less than the maximum 1.0 fps inflow velocity for mulched
areas, stated in Section 4.5, Drainage Considerations (page 38), of the April 1999 NCDENR Stormwater Best
Management Practices manual.
Thank you in advance for your time spent reviewing this additional information. Do not hesitate to contact me if you have
questions, comments or concerns about this information or other portions of the application.

REQUEST FOR MORE INFORMATION-EXPRESS REVIEW PROGRAM
Dear Sir or Madam:
On August 19, 2004, the Division of Water Quality (DWQ) received your application dated
August 19, 2004 to impact 0.7868 acres of wetlands, 155 feet of stream and 32,729 square feet
(ft2) of protected riparian buffers to construct the proposed Bridgewater Subdivision. The DWQ
has determined that your application was incomplete and/or provided inaccurate information as
discussed below. The DWQ will require additional information in order to process your
application to impact protected wetland, streams and/or buffers on the subject property.
Therefore, unless we receive the additional information requested below, we will have to move
toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8) and will
place this project on hold as incomplete until we receive this additional information. Please
provide the following information so that we may continue to review your project.
Additional Information:
Please submit three (3) full sized plans (to scale) of the following: drawing sheets, WL-1.0,
WL-2.0, WL-3.0, C-3.0, C-3.1 and C-16.0.
2. Please clarify what bypass method is to be used on level spreaders, FES 413, FES 20B and
FES 6013? Also, please make sure all level spreaders are located within drainage easements
for future maintenance.
3. Please submit an Operations and Maintenance Agreement for your level spreaders and
Bioretention Area, an example of this information can be found on our 401/Wetlands Unit
website: http://h2o.enr.state.nc.us/ncwetlands.
4. On your Biorentention Area Worksheet it was indicated that the inlet velocities are assumed to
be less than 1.0 fps. Please note that the inlet velocity must not exceed 0.67 fps.

Please respond within three days of the date of this letter by sending this information to me via
e-mail or fax and a follow-up copy in writing. The Express Review Program is a process that
requires all parties to participate in a timely manner. If the DWQ feels the Express Review
Program is the incorrect review program for your project, then we may have to return your
application and have it reviewed through our regular 401 Water Quality Certification Program.
This letter only addresses the application review and does not authorize any impacts to
wetlands, waters or protected buffers. Please be aware that any impacts requested within your
application are not authorized (at this time) by the DWQ. Please call Debbie Edwards at (919)
733-9502 if you have any questions regarding or would like to set up a meeting to discuss this
matter.
