Approval of Storm water Management Plan
Dear Mr. Methven:
Alan W. Klimek, P.E. Director
Division of Water Quality
DWQ Project # 04-1296
Wake County
On August 31, 2005 the Division of Water Quality (DWQ) received the revised storm water management plan
prepared by your engineer, Mr. Robbie Oldham, P.E., of Withers & Ravenel Engineers Planners, to comply with the
conditions of 401 Water Quality Certification issued on January 12, 2005.
The Plan has been reviewed and satisfies the storm water management conditions of the 401 and Neuse River Buffer
Rules as stated. The structural storm water practices as approved by DWQ as well as drainage patters must be
maintained in perpetuity. 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,
Neuse Buffer Rules and Non-discharge regulations.
No changes to the structural storm water practices shall be made without written authorization from the Division of
Water Quality. Storm water easements shall be recorded for a distance of at least 10 feet on each side of all storm
water conveyances on all lots containing these structures including future access for maintenance. The storm water
easements shall allow for the ability to maintain the structures, perform corrective actions as described above and
shall provide protection of the structures from potential alternations by future property owners. The authorization to
proceed with your proposed impacts or to conduct impacts to waters as depicted in your application and as
authorized by the Certification shall expire upon expiration of the 404 Permit.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act and the
Neuse riparian buffer protection rule as described within 15A NCAC 213 .0233. If you have any questions, please
telephone Sam A. Aghimien, at 919-733-3574.

Per your request, please find attached the Wet Detention Basin worksheet forAR-4 and the
impervious area exhibit for SF-4. As we discussed, please note that the wet pond was only
required to meet the Town of Cary oridance and not required for NCDWQ regulations. The Town
required the addition of a wet pond since we had impacts to the Town's soo' riparian buffer.
Therefore, the wet pond is not subject to NCDWQ requirements as long as diffused flow is meet
which it is. Regarding the SF-4 impervious area, we have checked the impervious areas for SF-4
and the areas now match Sheet a of the approved plans. Note that the sidewalk quantities have
been revised. We trust this information meets the conditions of the issued permit. Please call
with any questions. Thanks.

You have our approval, in accordance with the attached conditions and those listed below, to
place fill within or otherwise impact 0.075 acres of wetlands, 120 feet of streams and 31,935
square feet (ft) of protected riparian buffers for the purpose of constructing roads and
maintaining existing dams at the subject property, as described within your application dated
December 20, 2004 and received by the N.C. Division of Water Quality (DWQ) on December
20, 2004. After reviewing your application, we have decided that the impacts are covered by
General Water Quality Certification Number(s) 3402 and 3494 (GC3402 and GC3494). The
Certification (s) allows you to use Nationwide Permit(s) 39 and 3 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 213 .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 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 211.0506 (h). This approval requires you to follow the
conditions listed in the attached certification and any additional conditions listed below.

Dear Mr. Dorney and Ms. Wade:
On behalf of Centex Homes (Attn: Gray Methven), we hereby request authorization from
the US Army Corps of Engineers (USACE) to use Nationwide Permit 39 for proposed
permanent impacts to an intermittent stream resulting from a residential road crossing and
wetland impacts due to lot fill (See attached Overall Impacts Map). We also request
written concurrence from the North Carolina Division of Water Quality that the project
complies with the Neuse Buffer Rules for impacts associated with the proposed road
crossing. A Pre-construction Notification Application (PCN) is attached, which includes
an agent authorization form.
On November 21, 2002, S&EC conducted a detailed wetland delineation and Neuse
River/Cary Riparian Buffer evaluation on the Davis Drive Site. On December 9, 2002,
Ms. Andrea Wade of the USACE reviewed and agreed with S&EC's determination
regarding the wetlands and jurisdictional features occurring on property. A wetland
delineation map was submitted in March, 2004 to the USACE for approval, however we
have not received the signed copy as of yet. The subject site is located on the east side of
Davis Drive (SR 1613), approximately 2,000 feet north of the intersection of Davis Drive
and Salem Church Road (SR 1614). See attached vicinity map with the location of the

from north to south. In order to provide the infrastructure for the proposed subdivision
(i.e. roads, water, and sewer), stream crossings and impacts to the riparian buffer cannot
be avoided. The road is necessary to access the east side of the site as well as to provide
interconnectivity between nearby subdivisions. The proposed impacts consist of 148
linear feet of intermittent channel and 0.02 acres of jurisdictional wetlands resulting from
a road crossing (See Figure 3). The road will cross the channel at a nearly perpendicular
angle in order to minimize impacts to stream and buffers. The applicant will employ
appropriate sediment and erosion controls during construction and velocity dissipaters
will be installed. This portion of the project will comply with the general and regional
conditions of NWP 39. There will bean additional .05 acres of wetland impacts due to
grading and lot fill (See Figures 1 &2).
The USACE's current policy requires applicants to avoid and minimize wetland and
stream channel impacts to the maximum extent practicable and may require
compensatory mitigation to offset unavoidable losses for impacts to forested wetlands
that exceed 0.1 acres. The applicant requested a detailed delineation of wetlands present
on the site prior to construction in order to avoid wetland impacts. Because cumulative
impacts to the intermittent stream channel are less than 150 linear feet and wetland
impacts are less than one-tenth of an acre, S&EC does not believe compensatory
mitigation should be required by the USACE for this project.
Neuse River Buffer Compliance
NC-DWQ's current policy for impacts due to roadways does not require mitigation for
buffer impacts that are less than 1/3 of an acre or less than 150 linear feet of channel per
project. Because the impacts are below 1/3 of an acre and less than 150 linear feet at the
proposed road crossing, buffer mitigation should not be required by NC-DWQ.
Following construction, Phase SF-4 will contain 26.6% impervious surface, as calculated
by the project designer, therefore, we do not believe a pre-approved stormwater plan is
required. However, we have provided the NC-DWQ with the proposed stormwater plan
as well as the DWQ level-spreader work sheets in order to demonstrate that diffuse/non-
erosive flow will be achieved before stormwater enters the buffers.

Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a
delineation map, whether or not impacts are proposed to these systems. Wetland and stream
evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: The proposed impacts consist of
122 linear feet of intermittent channel and 0.02 acres of jurisdictional wetlands resulting from
a road crossing; (Figure 3) There will be an additional .05 acres of wetland impacts due to
lot fill (Figures 1 &2)

5. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
VI. 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.
A detailed delineation was conducted in order to develop a site plan that minimized impacts.
Because a channel bisects the property from north to south the proposed road crossing (Figure 31
cannot be avoided. However, the applicant is crossing the stream at a nearly perpendicular angle
in order to reduce impacts Wetland Impacts (Figure 1 & 2) consist of wetland fill resulting from
grading of lots and a road. The wetland and stream channel impacts are necessary in order to
provide safe ingress and egress and to provide access to the existing subdivision to the north.
Appropriate sediment-erosion control devices will be utilized in an effort to further minimize
impacts to the wetland & intermittent stream. Please see the attached Impact Maps (Figures 1-3)
& Storm Drainage-Erosion Control Plan.
VII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
Page 5 of 8
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://l12o.enr.state.nc.us/ncwetiands/strmgide.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.
Because impacts due to the road crossing are less than 150 linear feet & wetland fill
impacts have been limited to 0.07 acres S&EC does not believe mitigation should be
required If mitigation is required the applicant proposes payment to NCEEP.
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 http://h2o.enr.state.nc.us/wM/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): N/A
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
VIII. 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)?
Page 6 of 8
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No ?
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
IX. 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
(Neuse), 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:
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.
Road crossing impacts (Figure 3)
Zone* Impact
(square feet) Multiplier Required
Mitigation
1 7,599 3 N/A
2 3,792 1.5 N/A
Total 11,391 N/A
* Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone t.
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.
Buffer imnacts are below 1/3 of an acre and less than 150 linear feet at the proposed road
crossing-, therefore buffer mitigation should not be required by NC-DWQ.
Page 7 of 8
X. 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.
Following; construction Phase SF-4 will contain 26.6% impervious surface, as calculated by the
proiect designer, therefore we do not believe a pre-approved stonnwater plan is required.
However, we have provided the NC-DWQ with the proposed stormwater plan as well as the
DWQ level-spreader work sheets in order to demonstrate that diffuse/non-erosive flow will be
achieved before stormwater enters the buffers.
XI. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Sanitary Sewer
XII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application?
Yes ? No
XIII. 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: Bishop's Gate II
W&R Project 4204016
S&EC Project 07463.W1
Dear Todd:
We are providing you with the additional information you requested for this project per
your fax dated 7/16/04. Our responses to your comments are as follows:
1. We added these pipes at the Town of Cary's request to prevent overland flow of
stromwater across their greenway. They said that they had this approach approved
by DWQ at other locations. Please note that this level spreader is located just
outside of the Town of Cary Zone 3 riparian buffer and diffuse flow should be
accomplished prior to the stormwater entering DWQ's Zone 2.
2. The riprap dissipater pad was not included. The addition of this dissipater results in
a total of 148 If of stream impact. Let's discuss this in more detail to make sure there
are not any additional issues.
3. Our survey points file shows the existing elevation of the channel at the inlet as
416.0 and the outlet as 414.0. The pipe inlet invert is 415.0 and is therefore 1'
below the existing channel and the pipe outlet is at grade at 414.
4. The level spreader worksheets are attached as requested. Please note that Level
Af Spreaders A & B both discharge at the 100' zone 3 of the Cary riparian buffer,
which results in diffuse flow at the DWQ 50' zone 2 of the riparian buffer.
5. The stormwater management information for the road to the west is part of the AR-4
design. Robbie Oldham, of our office, will be providing you with this information
under separate cover later this week.
6. Again, this is part of the AR-4 design, which is a townhome development. Robbie
Oldham will provide you with the layout and any pertinent information.
7. The impervious % for the SF-4 development is 26.6% and for ARA is 29.61 %. The
A( combined project impervious percentage is therefore 27.45%.

We have provided you with this information for your review and comment. We will
make any revisions as needed so the appropriate information can be forwarded to the
reviewing agencies as soon as possible.
Please note that the greenway impacts will need to be submitted as a separate permit
with the Cary Parks, Recreation & Cultural Resources as the applicant like we did for
the Glenkirk greenway_ We will be providing you with the mapping and calculations
once we complete them.
Thanks for your continued assistance with this project- Please advise if you require
additional information or have any questions.

maintaining existing dams at the subject property, as described within your application dated
December 20, 2004 and received by the N.C. Division of Water Quality (DWQ) on December
20, 2004. After reviewing your application, we have decided that the impacts are covered by
General Water Quality Certification Number(s) 3402 and 3494 (GC3402 and GC3494). 1110
Certification(s) allows you to use Nationwide Permit(s) 39 and 3 when issued by the US Atx:ay
Corps of Engineers (USAGE). This letter shall also act as your approved Authorization
Certificate for impacts to the protected riparian buffers per 15A r(CAC 213 .0233. In addition,
you should obtain or otherwise comply with arty 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 Permit.
Thus 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 streara, compensatory mitigation may
be required as described in 15A NCAC 2H.0506 (h). 11iis approval requires you to follow the
conditions listed in the attached certification and any additional conditions listed below.

OPERATIONS AND MAINTENANCE MANUAL
Wet Detention Pond
This manual establishes procedures for maintenance and operation of Storm Water
Management device for Bishop's Gate P.U.D. - Parcel AR-4 in accordance with the
Town of Cary guidelines as set forth in Chapter 4 Part 4.4.6 of the Cary LDO.
SECTION I - MAINTENANCE OF DETENTION PONDS
Erosion - Erosion occurs when the water concentrates causing failure of the vegetation
or when vegetation dies and sets up the environment for rill erosion and eventually
gullies from the stormwater runoff. The areas should be inspected. Proper care of
vegetative areas that develop erosion is required to prevent more serious damage to
the site. 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. This can be corrected by reshaping, to more
evenly distribute the runoff to areas not experiencing erosion problems.
Rodent Control - Any rodents that have fallen into or that take residence within the
devices should be removed so that they do not present a source of blockage for the
discharge pipes.
Trash and Debris - Trash acts as a barrier to stormwater discharge and attracts
unwanted pests. The detention devices should be kept clear of debris such as loose
bottles, cans, food containers and other forms of rubbish.
SECTION II - MAINTENANCE OF THE CONTROL STRUCTURES
Inspection of Conduits - Conduits should be inspected thoroughly on a semi-annual
basis. 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. Problems with conduits
most often occur at joints and special attention should be given to them during
inspection. Joints should be checked for gaps caused by elongation or settlement and
loss of joint filler material. Open joints can permit erosion of the earthwork and possible
the piping of soil material through the joints. A depression in the soil surface over the
pipe may be signs that soil is being removed from around the pipe.
The riser structures should be visually inspected semi-annually for any seepage through
mortar joints or cracks in the walls of the structures. Any infiltration should be corrected
immediately as this will directly affect the devices ability to maintain its normal pool
elevation.
The orifices should be cleared of any debris that may build up around them and present
a source of blockage.
SECTION III - RECORD KEEPING
Operation of the storm water detention devices should include recording of the
following:
Semi-Annual Inspection Reports - A collection of written inspection reports
should be kept on record in Section IV of this manual. Inspection should be
conducted semi-annually. Copies should be provided to the Town of Cary
Stormwater Management Section of the Engineering Department.
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 IV 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.

Bishop's Gate Subdivision - USACE AID# 200320243; DWQ#04-1296
Cary, Wake County, North Carolina
S&EC Project #: 7463.W1
Dear Ms. Karoly and Ms. Wade:
On behalf of Centex Homes (Attn: Gray Methven), we hereby request authorization from
the US Army Corps of Engineers (USACE) to use Nationwide Permits 3 and 39 for
proposed permanent impacts to a perennial stream resulting from a residential road
crossing, wetland impacts due to lot fill, and impacts needed for maintenance to two farm
ponds (See attached Overall Impact Maps). We also request written concurrence from
the North Carolina Division of Water Quality that the project complies with the Neuse
Buffer Rules for impacts associated with the proposed road crossing. A Pre-construction
Notification Application (PCN) is attached, which includes an agent authorization form.
On November 21, 2002, S&EC conducted a detailed wetland delineation and Neuse
River/Cary Riparian Buffer evaluation on the Davis Drive Site. On December 9, 2002,
Ms. Andrea Wade of the USACE reviewed and agreed with S&EC's determination
regarding the wetlands and jurisdictional features occurring on property. A wetland
delineation map was submitted in March, 2004 to the USACE for approval.
As per the USACE letter dated September 15, 2004, the site plan has been revised and
impacts reduced. The proposed project will now impact 120 linear feet of channel and
0.15 acres of wetlands.
The subject site is located on the east side of Davis Drive (SR 1613), approximately
2,000 feet north of the intersection of Davis Drive and Salem Church Road (SR 1614).
See attached vicinity map with the location of the site on a USGS topographic
quadrangle.

Nationwide Permit 3
The applicant proposes to perform routine maintenance and dam improvements on the
existing ponds related to the project. Specifically, maintenance is needed on the
emergency spillway and includes the installation of a new riser and outlet. The water C
level for the ponds will not be changed from present conditions nor will the present use
(i.e. an amenity) of these ponds be altered. These activities are covered under r
Nationwide Permit 3. Specifically, NWP 3 authorizes activities related to repair,
rehabilitation, or replacement of any serviceable structure in order to restore it to the
condition as specified in the original permit. Impacts due to maintenance include 58
linear feet of perennial stream channel. Proposed maintenance activities will comply
with all of the general conditions, regional conditions, and water quality certifications;
therefore, this activity does not require written concurrence from the NC-DWQ. j
Nationwide Permit 39 0,
Ci
The purpose of this project is to construct a residential subdivision that will meet the ?demand for housing in this area. An unnamed, perennial channel bisects the property
from north to south. In order to provide the infrastructure for the proposed subdivision
(i.e. roads, water, and sewer), stream crossings and impacts to the riparian buffer cannot \rn?..
be avoided. The road is necessary to access the east side of the site as well as to provide
interconnectivity between nearby subdivisions. The proposed impacts consist of 120 ?
linear feet of intermittent channel, 0.02 acres of jurisdictional wetlands and 8,858 sq. ft. - y?
of riparian buffer (Z1: 5,080, Z2: 3,778) resulting from a road crossing. The road will
cross the channel at a nearly perpendicular angle in order to minimize impacts to stream
and buffers. The applicant will employ appropriate sediment and erosion controls during
construction and velocity dissipaters will be installed. This portion of the project will \i w
comply with the general and regional conditions of NWP 39. There will be an additional t Y
0.05 acres of wetland impacts due to grading and lot fill. Total wetland impacts consist U
of 0.075 acres, including repairs to the dam. Because stream impacts exceed 150 linear ! kiT
y
\
feet, the applicant proposes payment to the NCEEP to satisfy mitigation requirements.
Neuse River Buffer Compliance \
NC-DWQ's current policy for impacts due to roadways does not require mitigation for
buffer impacts that are less than 1/3 of an acre or less than 150 linear feet of channel per \
project. Because the impacts are below 1/3 of an acre and less than 150 linear feet at the
proposed road crossing, buffer mitigation should not be required by NC-DWQ. As stated ,y. .
above, cumulative impacts to perennial channels will exceed 150 linear for this project, (;? 1
therefore the applicant proposes payment to the NCEEP to satisfy mitigation
requirements. ?? VA

Following construction, Phase SF-4 will contain 26.6% impervious surface, as calculated
by the project designer, therefore, we do not believe a pre-approved stormwater plan is
required. However, the NC-DWQ was provided with the proposed stormwater plan as
well as the DWQ level-spreader work sheets in order to demonstrate that diffuse/non-
erosive flow will be achieved before stormwater enters the buffers in our previous
application.

VI. 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.
A detailed delineation was conducted in order to develop a site plan that minimized impacts
Because a channel bisects the property from north to south the proposed road crossing (Figure 31
cannot be avoided. However, the applicant is crossing the stream at a nearly perpendicular angle
in order to reduce impacts. In order to reduce impacts the applicant will utilize concrete
headwalls at the road crossing. The original application proposed 122 linear feet of impact
however, the impacts have be reduced to 62 linear feet
Dam maintenance is necessary to maintain the integrity of the ponds associated with the
project and for safety to protect downstream homes and/or roads from flooding
VII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
Page 5 of 8
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
bttp://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.
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 http://h2o.enr.state.ne.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): 240
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A

VIII. 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 ?
IX. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .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:
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

*s
cone t extends out su teet erpendic ar from near bank of channel; Zone 2 extends an
additional 20 feet from the e one 1.
Because this is considered an cxrmpt activity, we do not believe buffer mitigation will be required.
X35 ,?
?? Page 7 of 8
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.
Buffer impacts are below 1/3 of an acre and less than 150 linear feet at the proposed road
crossing, therefore, buffer mitigation should not be required by NC-DWO
X. 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.
Following construction Phase SF-4 will contain 26.6% impervious surface as calculated by the
project designer, therefore we do not believe a pre-approved stonnwater plan is required
However, we have provided the NC-DWQ with the Droposed stormwater plan as well as the
DWQ level-spreader work sheets in order to demonstrate that diffuse/non-erosive flow will be
achieved before stor nwater enters the buffers.
XI. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Sanitary sewer
XII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application?
Yes ? No
XIII. 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 die applicant's
control).

Dear Ms. Karoly,
As part of the permit approval for the proposed Bishops Gate Subdivision, condition `3'
of the 401 required a review of the stormwater plan to insure that diffuse flow
requirements are met (see attached). Included with the attachments are detailed
breakdowns of the percent impervious, level spreader worksheets, and full-scale
stormwater plans for each tract. Please feel free to call if you have any questions or
require additional information.

permit other than NIVP 3. We understand that regardless of how the USACE permits
these impacts that they will require mitigation for all stream impacts.
3. Diffuse Flow (Review) - All constructed stormwater conveyance outlets shall be directed and
maintained to flow in a diffuse manner at non-erosive velocities tlu-ough the entire protected
stream buffers without re-concentrating. If this is not possible it may be necessary to provide
stormwater facilities that are considered to remove nitrogen. Additionally, a stormwater
