Please note: The site plans have been revised slightly since our initial submission,
the roadway impacts associated with impact A have been reduced by 6 linear feet.
Additionally, as requested by NC-DWQ (February 7, 2003) we have included plan
details and calculations for the BMP devices and included plan details for crossing
A. This crossing has been depressed one foot below the stream invert in order to
allow for aquatic life passage.

Glenkirk-P.U.D.
Cary, Wake County, North Carolina
S&EC Project #: 01-6599
Dear Ms. Wade and Mr. Dorney,
On behalf of John Weiland Homes and Neighborhoods of NC, we hereby request
authorization from the US Army Corps of Engineers (USACE) to use Nationwide
Permits 12 and 14 to cover impacts to stream channels (see attached overall map). We
also request written concurrence from the North Carolina Division of Water Quality (NC-
DWQ) that the project complies with the 401 Water Quality Certifications associated
with Nationwide Permit 12 and 14. A Pre-construction Notification Application (PCN) is
attached, which includes an agent authorization form.
The proposed project consists of impacts from the construction of access roads for a
residential housing development and a sewer line. The project is located approximately
3000 feet east of the intersection of Cary Parkway and High House Road (SR 1615) and
is bordered on the east by Coles Branch Creek. The site is approximately 80 acres in size
and consists of undeveloped, forested land. Please refer to the attached USGS map,
which displays the location of the proposed project.

S&EC performed a detailed wetland delineation and buffer evaluation on the property in
October of 2001. Mr. Charles Brown of the NC-DWQ performed a site meeting to
confirm the buffer determination on November 26, 2002. A copy of Mr. Brown's buffer
letter is also attached. Ms. Andrea Wade of the USACE approved the delineation on
October 28, 2002 (AID #200320144). On April 8, 2003, Mr. Dave Penrose conducted a
site meeting and determined that the location of channel crossing A will impact a
perennial/'significant channel.
The applicant requested a detailed wetland delineation and buffer evaluation on the
property prior to site plan development in order to avoid jurisdictional wetlands and
waters and riparian buffers to the maximum extent practicable. The proposed roadways
will permanently impact a total of 229 linear feet of stream channels (1761.f. of perennial
and 53 l.f. of intermittent channel). Temporary impacts associated with the installation of
the sanitary sewer easement consist of 92 linear feet of channel impact and a total of
36,645 square feet of Neuse Buffer impacts. These impacts are elaborated upon within
the attached PCN form and are shown on the attached inset impact maps. Please note that
construction drawings are for phase I of the project only. However, we have provided the
proposed impacts for all phases of the subdivision.
The proposed roadways are needed to gain access to the entire property. A perennial
channel and an intermittent channel bisect the property from north to south; therefore,
impacts A and F are unavoidable in order to gain access to the eastern portion of the
property. Moreover, these impacts are required in order to comply with the Town of
Cary's connectivity ordinance, as described in the attached justification letter provided by
Withers and Ravenel (dated Dec. 9, 2003, March 12, 2003). The remaining impacts on-
site consist of 92 linear feet (221f. + 22 l.f. + 271.f. + 21 l.f. = 92 11.) of temporary
channel impacts associated with a sewer outfall. These crossings are exempt from the
buffer rules (i.e. perpendicular, <40 linear feet); however, we have provided the buffer
impacts for your information.
Due to the steep grade at this site (>10%) level spreaders would not adequately provide
diffuse flow through the buffers. Therefore the applicant has proposed the construction
of wetland BMP devices as an alternative to level spreaders. The berm of one of these
devices will impact approximately 1,530 sq. ft. of Zone 2, and 274 sq.ft. of Zone 1 of the
buffer (Impact I). These areas will be re-vegetated following construction. Please also
see the attached Justification letter provided by Withers & Ravenel (December 19, 2002).
As noted on the site plans, additional wetland BMP devices will be constructed outside of
the buffers in order to capture and treat the first inch of run-off and release it slowly and
diffusely through the buffers. The remaining impacts depicted on the attached site plan
are exempt (i.e. grading and reveg.) or outside of the Neuse Buffer but within the Town
of Cary 100-foot riparian buffer.
The USACE's current policy requires applicants to avoid and minimize wetland and
stream channel impacts to the maximum extent practicable and compensatory mitigation
to offset unavoidable losses of waters of the US when impacts exceed the requirements
for notification (0.10 acre). To minimize impacts, the applicant conducted a detailed
wetland delineation prior to site plan development. However, in order to comply with the
Town of Cary's connectivity ordinance and to access the entire parcel, stream impacts
were unavoidable. Moreover, the presence of an existing utility line and an underground
fuel line limited the design options for at stream crossing `A' (see attached justification
letter). Due to the length of channel impacts (176 LF), a site meeting was conducted with
Ms. Andrea Wade of the USACE in order to determine the mitigation ratio for the stream
impacts. Ms. Wade determined that the payment ratio should be 1:1. We have forwarded
a copy of this application and a request for mitigation payment to the Wetlands
Restoration Program.
NC-DWQ's current policy requires written concurrence for stream impacts of greater or
equal to 150 linear feet of stream length per project. We request written concurrence that
the project complies with the 401 Water Quality Certification associated with Nationwide
Permit 12 and 14. NC-DWQ's current policy requires wetland or stream mitigation for
perennial stream channel impacts above 1 acre and 150 linear feet per project. Although
mitigation is typically required for impacts that exceed 150 linear feet of perennial
channel, it should be noted that due to engineering constraints it was not possible to
reduce the impacts at crossing `A'. Specifically, retaining walls were not feasible due to
the proximity of the existing sewer line and an underground aviation fuel pipeline.
Please see the attached justification letter provided by the project engineer for further
explanation. If mitigation is required for these impacts, we propose payment in to the
Wetlands Restoration Program for stream and riparian buffer impacts. A copy of this
application and our request for mitigation payments has been forwarded to WRP for
review. Following construction the site will contain less than 30% impervious surface
and because water quality will be preserved down stream through the use of extended
detention wetlands, we do not believe that this project requires a pre-approved
stormwater plan.
NC-DWQ's current policy requires written concurrence for riparian buffer impacts for
road crossings that exceed 40 linear feet. We are requesting buffer compliance for the
two road crossings associated with this project. Current NC-DWQ policy requires buffer
mitigation if stream impacts exceed 150 linear feet or if buffer impacts are greater than
0.33 acres. Because crossing A exceeds 150 linear, feet we propose payment into the
WRP for buffer impacts. As stated above we are forwarding a copy of this application
and a request for payment to WRP.
Please call if you require any additional information or have any questions.
Sincerely,

Todd Preuninger

HOC
Please find attached one (1) copy of the revised wetlands riparian buffer impact maps for the above-
referenced project. Please note that the site plan for this project has been revised to accommodate
the existing Colonial Pipeline aviation fuel line crossing of Olde Weatherstone Way. Olde
Weatherstone Way was realigned and lots within this area also were revised to better accommodate
this pipeline. Please note that we have revised sheets 1-2 and 1-3 to cover these revisions. Please
note that the Zone 1 riparian buffer impacts were slightly increased and Zone 2 impacts were slightly
decreased from the previous submittal. Also the channel impact for the main roadway crossing was
reduced 6 linear feet, as shown on the attached maps.
I am also responding to the DWQ letter dated February 7, 2003. Our responses to the comments
contained in this letter are as follows:
1. All discharge points into riparian buffers are discharged via alternative level spreaders or
constructed wetlands as shown on the attached plans numbered Sheets 11 and 12.
Calculations are also attached.
2. Buffer feature labeled F is shown on Sheet 1-i.
3. Storm crossing plan detail for crossing A is attached. The inverts are depressed 1 foot to allow
for aquatic life passage.
Please advise if you require additional information or have any questions concerning this
information. Please advise us of your anticipated schedule for obtaining new permits for this
project.

local stormwater requirement, etc.): NA
Size of watershed draining to pond: NA Expected pond surface area: NA
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The proposed roadways are needed to gain access to the entire property perennial channel
bisects the property from north to south• therefore impact A is unavoidable in order to train
access to the eastern portion of the property. In addition it will be necessary to impact an
intermittent channel (Impact R in order to comply with the Town of Cary's connectivity
ordinance However, the crossing is aligned as close to the top of the drainage as possible in
order to minimize channel impacts to the maximum extent practicable. Temporary impacts
resulting from the construction of the proposed sewer easement are necessary to connect to the
existing sewer easements as shown on the attached impact map. Impacts H, K, L and M are
temporary channel impacts associated with utility line installation. Although mitigation is
typical required for impacts that exceed 150 linear feet of perennial channel, it should be noted
that due to engineering constraints it was not possible to reduce the impacts at crossing `A'.
Specifically, rretaining walls were not feasible due to the proximity of the existing sewer line and
an underground aviation fuel pipeline Please see the attached justification letter provided by the
project engineer for further explanation.

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
http://'h2o.enr.state.nc.us/ncwetlands/stn-ngide.htmi.
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.
Mitigation requirements will be satisfied by payment into the Wetland Restoration Program.
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

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 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ® No ? If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.

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.
The applicant proposes payment to WRP
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.
Impervious surface following construction will be less than 30% and because downstream water
quality will be protected through the use of constructed wetlands we do not believe a pre-
approved stormwater plan should be required by, DWO
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Sanitary sewer treatment
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: Glenkirk Subdivision
WR Project #202139
S&EC Project #6599
Mr. Preuninger:
We are providing this letter at your request to provide supplemental data regarding the project's
proposed wetland & riparian buffer impacts. We understand this information to be required for the
review and approval of the proposed impacts by the US Army Corps of Engineers and the North
Carolina Department of Environment and Natural Resources.
The proposed project lies within the Neuse River basin and consists of t 158 single-family home
sites and a community recreation area on approximately 8o acres. The proposed project impervious
surface percentage is below 30% including the associated open space dedication. Currently
construction drawings have been completed for phase 1 of the development only. However, we have
provided proposed impact maps for all phases of the subdivision construction.
The perennial stream channel, impacted by roadway crossing A, bisects the site from south to north.
The primary orientation of the site is from east to west necessitating a channel crossing be
constructed. Crossing A serves a collector roadway required by the Town of Cary that will serve the
surrounding neighborhoods, an existing Wake County elementary school in addition to connecting
two. major Town of Cary thoroughfares. In order to minimize impacts we have designed this crossing
with 2:1 fill slopes and headwalls. The design process included consideration of additional retaining
walls and lower crossing height. Retaining walls were not feasible due to the close proximity of the
existing sanitary sewer facilities. Decreased crossing height was not feasible due to existing
topography, minimum roadway design criteria and conflicts with an existing underground aviation
fuel pipeline.
The intermittent stream impacted by crossing F is required to gain access to approximately 60% of
the site area, which is bounded on the other sides by existing development and perennial streams.
The crossing is unavoidable due to Town of Cary connection requirements to the existing roadway
stub. The crossing is proposed at the extreme upper end of the drainage feature as close as
practicable to the property boundary to minimize impacts.
Utility impacts B, C, D and J are riparian buffer impacts only and do not encroach into wetland areas.
These impacts are necessary to tie into the existing sanitary sewer outfall facilities. Utility impacts
H, K, L and M are necessary for similar reasons but will require temporary channel impacts to
perennial streams. All of these impacts avoid upland wetland disturbance and are designed in a
manner that would typically be exempt from buffer impact notification requirements. We provide this
data for informational purposes.
iii MacKenan Drive i Cary. North Carolina 27511 1 tel: [phone] fax: [phone] i www.withersraveneLcom
Impact I is proposed as a constructed wetland BMP facility. It is proposed as a buffer impact due to
the extreme topography, (greater than io%) in the subject area. The buffer area proposed for impact
is void of upland wetland areas but is more level to ease BMP construction and minimize existing
vegetation removal from the erodable steep slopes and provide maximum stormwater treatment.
Impacts E and G are limited to grading in the Town of Cary's 50 to loo' buffer area and are designed
to be alternative level spreading devices that capture and release the first inch of runoff and release
it slowly and diffusely through the riparian buffer. These practices further comply with the Town of
Cary's stormwater management ordinance
We trust the above information will assist in your obtaining disturbance permits for the proposed
project. Please advise should you require any additional information.
Sincerely,
WITHERS &-RAVENEL, INC.

Dear Ms. Gadd:
It was determined that there are channels present on the property shown on either the Wake
County Soil Survey and /or USGS Cary, NC quad map that-are subject to protection under the
Neuse River Basin: Nutrient Sensitive Waters Management Strategy; Protection and
Maintenance of Existing Riparian Areas, North Carolina Administrative Code T15A:02B.0233.
The specific portions of the channels subject to the buffer rules include Feature A, Feature B
(below flag # 102), Feature F (below flag # 106), and Feature E which are shown on the attached
map. Features marked C & D are not subject to the Neuse Riparian Rule.
This letter only addresses the applicability of the Neuse Buffer Rules. For information relevant
to wetlands and other impacts, please contact the Central Office at 733-1786. Thank you for
your attention to this matter and if this Office can be of any assistance of if you have additional
questions, please do not hesitate to contact us.

Dear Mr. Patsey:
"t
to
On February 3, 2003 the Division of Water Quality (DWQ) was notified by receipt of your application
regarding your plan to fill waters for the purpose of constructing a residential housing development in Wake
County. Approval from DWQ is required to disturb these streams/buffers. Please provide 7 copies of the
following information and refer to the DWQ # listed above in your reply. Please show these on maps of suitable
scale (for instance 1" = 100 feet) so we can begin to determine your projects' compliance with 15A NCAC 2H
.0500.
1. Please provide a plan detail and calculations that show that all stormwater from discharge points
will either flow in a diffuse manner through the protected buffers (per the Level Spreader design
Guidance Document) or will first receive treatment through a nitrogen removing best
management practices such as a constructed wetlands.
2. Please show the location of the protected buffers on the featured labeled F on "Figure 2 - Soil
Survey" in order to determine if the adjacent lots are buildable.
3. Please provide stream crossing plan details for crossing A that shows aquatic life passage.
Please telephone Todd St. John at 919-733-9584 if you have any questions or would require copies of our
rules or procedural materials. This project will remain on hold as incomplete in accordance with 15A NCAC 2H
.0505(c). The processing time for this application will begin when this information is received. If we do not hear
from you by writing within three (3) weeks we will assume you no longer want to pursue the project and will
consider it withdrawn.

FEB - 3 2003
Dear Ms. Wade and Mr. Dorney,
On behalf of John Weiland Homes and Neighborhoods of NC, we hereby request
authorization from the US Army Corps of Engineers (USACE) to use Nationwide
Permits 12 and 14 to cover impacts to stream channels (see attached overall map). We
also request written concurrence from the North Carolina Division of Water Quality (NC-
DWQ) that the project complies with the 401 Water Quality Certifications associated
with Nationwide Permit 12 and 14. A Pre-construction Notification Application (PCN) is
attached, which includes an agent authorization form.
The proposed project consists of impacts from the construction of access roads for a
residential housing development and a sewer line. The project is located approximately
3000 feet east of the intersection of Cary Parkway and High House Road (SR 1615) and
is bordered on the east by Coles Branch Creek. The site is approximately 80 acres in size
and consists of undeveloped, forested land. Please refer to the attached USGS map,
which displays the location of the proposed project.
S&EC performed a detailed wetland delineation and buffer evaluation on the property in
October of 2001. Mr. Charles Brown of the NC-DWQ performed a site meeting to
confirm the buffer determination on November 26, 2002. A copy of Mr. Brown's buffer
letter is also attached. Ms. Andrea Wade of the USACE approved the delineation on
October 28, 2002 (AID #200320144).

. j; FILE COPY bruary 3, 2003
The applicant requested a detailed wetland delineation and buffer evaluation on the
property prior to site plan development in order to avoid jurisdictional wetlands and
waters and riparian buffers to the maximum extent practicable. The proposed roadways
will permanently impact a total of 235 linear feet of stream channels (182 1.f. of perennial
and 53 11 of intermittent channel). Temporary impacts associated with the installation of
the sanitary sewer easement consist of 92 linear feet of channel impact and a total of
36,645 square feet of Neuse Buffer impacts. These impacts are elaborated upon within
the attached PCN form and are shown on the attached inset impact maps. Please note that
construction drawings for phase I of the project only. However, we have provided the
proposed impacts for all phases of the subdivision.
The proposed roadways are needed to gain access to the entire property. A perennial
channel and an intermittent channel bisect the property from north to south; therefore,
impacts A and F are unavoidable in order to gain access to the eastern portion of the
property. Moreover, these impacts are required in order to comply with the Town of
Cary's connectivity ordinance, as described in the attached justification letter provided by
Withers and Ravenel (dated Dec. 9, 2002). The remaining impacts on-site consist of 92
linear feet (221f. + 221.f. + 27 l.f. + 21 l.f. = 92 l.f.) of temporary channel impacts
associated with a sewer outfall. These crossings are exempt from the buffer rules (i.e.
perpendicular, <40 linear feet); however, we have provided the buffer impacts for your
information.
Due to the steep grade at this site (>10%) level spreaders would not adequately provide
diffuse flow through the buffers. Therefore the applicant has proposed the construction
of wetland BMP devices as an alternative to level spreaders. The berm of one of these
devices will impact approximately 1,530 sq. ft. of Zone 2, and 274 sq.ft. of Zone 1 of the
buffer (Impact I). These areas will be re-vegetated following construction. Please also
see the attached Justification letter provided by Withers & Ravenel (December 19, 2002).
As noted on the site plans, additional wetland BMP devices will be constructed outside of
the buffers in order to capture and treat the first inch of run-off and release it slowly and
diffusely through the buffers. The remaining impacts depicted on the attached site plan
are exempt (i.e. grading and reveg.) or outside of the Neuse Buffer but within the Town
of Cary 100-foot riparian buffer.
The USACE's current policy requires applicants to avoid and minimize wetland and
stream channel impacts to the maximum extent practicable and compensatory mitigation
to offset unavoidable losses of waters of the US when impacts exceed the requirements
for notification (0.10 acre). To minimize impacts, the applicant conducted a detailed
wetland delineation prior to site plan development. However, in order to comply with the
Town of Cary's connectivity ordinance and to access the entire parcel, stream impacts
were unavoidable. Moreover, the presence of an existing utility line and an underground
fuel line limited the design options for at stream crossing `A' (see attached justification
letter). Due to the length of channel impacts (182 LF), a site meeting has been scheduled
with Ms. Andrea Wade of the USACE in order to determine whether mitigation will be
required and at what ratio. If the USACE requires mitigation for this project we propose
payment to the Wetlands Restoration Program. We have forwarded a copy of this
application and a request for mitigation payment to the Wetlands Restoration-Program.
NC-DWQ's current policy requires written concurrence for stream impacts of greater or
equal to 150 linear feet of stream length per project. We request written concurrence that
the project complies with the 401 Water Quality Certification associated with Nationwide
Permit 12 and 14. NC-DWQ's current policy requires wetland or stream mitigation for
perennial stream channel impacts above 1 acre and 150 linear feet per project. Although
mitigation is typically required for impacts that exceed 150 linear feet of perennial
channel, it should be noted that due to engineering constraints it was not possible to
reduce the impacts at crossing `A'. Specifically, retaining walls were not feasible due to
the proximity of the existing sewer line and an underground aviation fuel pipeline.
Please see the attached justification letter provided by the project engineer for further
explanation. If mitigation is required for these impacts, we propose payment in to the
Wetlands Restoration Program for stream and riparian buffer impacts. A copy of this
application and our request for mitigation payments has been forwarded to WRP for
review. Following construction the site will contain less than 30% impervious surface
and because water quality will be preserved down stream through the use of extended
detention wetlands, we do not believe that this project requires a pre-approved
stormwater plan.
NC-DWQ's current policy requires written concurrence for riparian buffer impacts for
road crossings that exceed 40 linear feet. We are requesting buffer compliance for the
two road crossings associated with this project. Current NC-DWQ policy requires buffer
mitigation if stream impacts exceed 150 linear feet or if buffer impacts are greater than
0.33 acres. Because crossing A exceeds 150 linear, feet we propose payment into the
WRP for buffer impacts. As stated above we are forwarding a copy of this application
and a request for payment to WRP.
Please call if you require any additional information or have any questions.
Sincerely,
Todd Preuninger Laura Gadd
Biologist Wetland Scientist

draw-down valve or spillway, etc.): NA
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): NA
Size of watershed draining to pond: NA Expected pond surface area: NA
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The proposed roadways are needed to gain access to the entire property. A perennial channel
bisects the property from north to south; therefore impact A is unavoidable in order to gain
access to the easternportion of the property. In addition it will be necessary to impact an
intermittent channel (Impact F) in order to comply with the Town of CT y's connectivity
ordinance However, the crossing is aligned as close to the top of the drainage as possible in
order to minimize channel impacts to the maximum extent practicable. Temporary impacts
resulting from the construction of the proposed sewer easement are necessary to connect to the
existing sewer easements as shown on the attached impact map Impacts H K L and M are
temporary channel impacts associated with utility line installation. Although mitigation is
typically required for impacts that exceed 150 linear feet of perennial channel it should be noted
that due to engineering constraints it was not possible to reduce the impacts at crossing `A'.
Specifically, retaining walls were not feasible due to the proximity of the existing sewer line and
an underground aviation fuel pipeline Please see the attached justification letter provided by the
project engineer for further explanation.

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
http://h2o.enr.state.nc.us/ncwetlands/stnngide.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.
Mitigation requirements will be satisfied by payment into the Wetland Restoration Program.
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/wip/index.htm. If use of

RE: Glenkirk Subdivision
WR Project #202139
S&EC Project #6599
Mr. Preuninger:
We are providing this letter at your request to provide supplemental data regarding the project's
proposed wetland & riparian buffer impacts. We understand this information to be required for the
review and approval of the proposed impacts by the US Army Corps of Engineers and the North
Carolina Department of Environment and Natural Resources.
The proposed project lies within the Neuse River basin and consists of ± 158 single-family home
sites and a community recreation area on approximately 8o acres. The proposed project impervious
surface percentage is below 30% including the associated open space dedication. Currently
construction drawings have been completed for phase 1 of the development only. However, we have
provided proposed impact maps for all phases of the subdivision construction.
The perennial stream channel, impacted by roadway crossing A, bisects the site from south to north.
The primary orientation of the site is from east to west necessitating a channel crossing be
constructed. Crossing A serves a collector roadway required by the Town of Cary that will serve the
surrounding neighborhoods, an existing Wake County elementary school in addition to connecting
two major Town of Cary thoroughfares. In order to minimize impacts we have designed this crossing
with 2:1 fill slopes and headwalls. The design process included consideration of additional retaining
walls and lower crossing height. Retaining walls were not feasible due to the close proximity of the
existing sanitary sewer facilities. Decreased crossing height was not feasible due to existing
topography, minimum roadway design criteria and conflicts with an existing underground aviation
fuel pipeline.
The intermittent stream impacted by crossing F is required to gain access to approximately 60% of
the site area, which is bounded on the other sides by existing development and perennial streams.
The crossing is unavoidable due to Town of Cary connection requirements to the existing roadway
stub. The crossing is proposed at the extreme upper end of the drainage feature as close as
practicable to the property boundary to minimize impacts.
Utility impacts B, C, D and J are riparian buffer impacts only and do not encroach into wetland areas.
These impacts are necessary to tie into the existing sanitary sewer outfall facilities. Utility impacts
H, K, L and M are necessary for similar reasons but will require temporary channel impacts to
perennial streams. All of these impacts avoid upland wetland disturbance and are designed in a
manner that would typically be exempt from buffer impact notification requirements. We provide this
data for informational purposes.
iii MacKenan Drive i Cary, North Carolina 27511 1 tel: [phone] fax: [phone] i www.withersravenel.com

Impact I is proposed as a constructed wetland BMP facility. It is proposed as a buffer impact due to
the extreme topography, (greater than 1o%) in the subject area. The buffer area proposed for impact
is void of upland wetland areas but is more level to ease BMP construction and minimize existing
vegetation removal from the erodable steep slopes and provide maximum stormwater treatment.
Impacts E and G are limited to grading in the Town of Cary's 50 to loo' buffer area and are designed
to be alternative level spreading devices that capture and release the first inch of runoff and release
it slowly and diffusely through the riparian buffer. These practices further comply with the Town of
Cary's stormwater management ordinance
We trust the above information will assist in your obtaining disturbance permits for the proposed
project. Please advise should you require any additional information.
Sincerely,

Dear Ms. Gadd:
It was determined that there are channels present on the property shown on either the Wake
County Soil Survey and /or USGS Cary, NC quad map that are subject to protection under the
Neuse River Basin: Nutrient Sensitive Waters Management Strategy; Protection and
Maintenance of Existing Riparian Areas, North Carolina Administrative Code T15A:02B.0233.
The specific portions of the channels subject to the buffer rules include Feature A, Feature B
(below flag # 102), Feature F (below flag # 106), and Feature E which are shown on the attached
map. Features marked C & D are not subject to the Neuse Riparian Rule.
This letter only addresses the applicability of the Neuse Buffer Rules. For information relevant
to wetlands and other impacts, please contact the Central Office at 733-1786. Thank you for
your attention to this matter and if this Office can be of any assistance of if you have additional
questions, please do not hesitate to contact us.
Since ely,
