Dear Mr. Domey,
On July 16'x', 2002, S&EC received correspondence from NC-DWQ stating that the 401-
Water Quality Certification application and Neuse River Buffer compliance request for
the Park at Langston (DWQ project no.: 020831) had been considered withdrawn by NC-
DWQ. We are hereby resubmitting the 401-Water Quality Certification application and
-io-Neuse River Buffer compliance request, despite the fact that we feel that the application
should have been placed on administrative hold rather than having been considered
withdrawn by NC-DWQ. However, instead of debating this issue, we are resubmitting
the application in order to best serve the interests of our client.
Enclosed are seven copies of the original application as well as seven copies of the site
stonnwater plan drafted by the project engineer.
Please call me if you require any additional information, or email me at

The Division of Water Quality has reviewed your response, received June 26, 2002, to our request for
additional information regarding your application for a 401 Certification and Neuse Buffer Rules Approval, received May
24, 2002, for the subject project.
In previous correspondence dated June 4, 2002, this Office requested that you provide plans and calculations
to show that diffuse flow of stormwater would be provided in the Neuse Riparian Buffers in compliance with 15A NCAC 213
.0233 (5). Only one plan page was provided that indicated some kind of level spreader for one of the five listed stormwater
outlets. No calculations were provided to show that this level spreader is adequately sized, and no topographic
information was provided to show that the slopes were adequate to accept the flow. No calculations or (readable) plans
were provided for the other outlets. This information was needed by DWQ in order for us to decide whether this project is
approvable.
Since the requested information was not provided, we are hereby returning the subject application. As such,
this application is withdrawn. Should you decide to reapply you must provide seven copies of an application and
supporting documentation as well as the appropriate fee.
If you have any questions please contact Todd St. John at 919-733-9584 or John Dorney at 919-733-9646 if

RE: Nationwide Permits 12 and 39, 401-Water Quality Certification, and Neuse
River Buffer Rules Compliance Request
Park at Langston
Cary, Wake County, North Carolina
UTM coordinates: 703500mE 39, 39750mN
S&EC Project #: 5968
Dear Mr. Dorney and Ms. Jones,
On behalf of William Barker, (property owner), we hereby request authorization from the
US Army Corps of Engineers to use Nationwide Permits 12 and 39 for the subject project
to cover permanent impacts to stream channels and wetlands. We also request written
concurrence from the NC Division of Water Quality (NC-DWQ) that the project
complies with the 401-Water Quality Certification associated with Nationwide Pen-nit 39,
and that it complies with the Neuse River Riparian Buffer rules. A Pre-construction
Notification Application (PCN) is attached, which includes an agent authorization form.
S&EC performed a Neuse River Buffer evaluation for the site in fall 2000, and a detailed
wetland delineation in April 2002, which was submitted to the USACE for approval on
May 20th, 2002. Data forms for the delineation are attached. NC-DWQ confinned
S&EC's Neuse River Buffer evaluation (NBRRO 01-199-see attached).
The proposed project, which consists of a residential subdivision, is located east of West
Lake Rd. (SRI 387), west of Bells Lake Rd. (SR 1386), approximately one mile south of
Ten-Ten Rd. (SR 1010) near Cary, Wake County, NC. Please refer to the USGS site
map. The property comprises approximately 32 acres, and is in the Neuse River Basin.
Approximately 0.003 acres (1,278 ft. 2) of jurisdictional wetlands and 85 linear ft. of
stream channel will be impacted for a roadway crossing (Impact 1-see impact maps)
under Nationwide Permit 39 (totaling 0.03 acres/85 linear ft.). Approximately 9,983 ft.2
(zone 1: 6,291 ft. 2, zone 2: 3,692 ft.2) of Neuse River Buffer will be impacted by the
proposed roadway crossings (Impact 1). Approximately 0.011 acres (495 11.) of
jurisdictional wetlands and 20 linear ft. of stream channel will be temporarily impacted
under NWP 12 (Impact 2-see impact maps). Total proposed impacts are 0.0411 acres
(0.011 temporary)/ 105 linear ft. (20 ft. temporary).
The Town of Cary originally required two roadway crossings over the channel where
proposed impacts will occur in order to preserve connectivity within the site-despite our
client's wishes-who understood that the two crossings conflicted with avoiding and
minimizing unnecessary impacts to wetlands/waters of the U.S. Thus, William Barker
(our client), S&EC, and a project engineer from CH Engineering met with Bob Zarzecki
of NC-DWQ in January to discuss the crossing requirement. After this meeting, the
project's land planner and engineer were able to convince Cary to drop one of the
required roadway crossings, leaving the one proposed in this application, which is
necessary to access high ground in the northeastern portion of the property. Additionally,
DOT has relaxed the minimum turn radius requirement for the extension of Alphawood
Drive (see impact map) in order to minimize Neuse River buffer impacts.
It is important to note that the road shown entering the site on the northern property line
is not yet constructed, and is a reserved road right-of-way-not a dedicated right-of-way.
Thus, the road right-of-way is still owned by the adjacent site's developer. Additionally,
there is a gas line easement parallel to the northern property line immediately adjacent to
the property.
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 of waters of the US when impacts
exceed the requirements for notification. The proposed roadway crossing is necessary in
order to access high ground in the northeastern portion of the property. This road is an
extension of a stubbed road on the western property line. Both the roadway and sewer
line crossing, as evinced by the site plan, have been designed to cross wetland areas and
the stream channel perpendicularly. A large, contiguous bottotnland hardwood forest
wetland in the middle of the property has been completely avoided, as have all other
wetlands/waters of the U.S. onsite.
NC-DWQ's current policy does not require mitigation for wetland and stream channel
impacts below 1 acre and 150 linear feet of significant channel per project. Because the
proposed cumulative impacts resulting from the project total 0.0411 acres (0.011 acres
temporary)/105 linear ft. (20 ft. temporary), project impacts are below the
aforementioned thresholds, and S&EC believes that neither wetland nor stream channel
mitigation should be required
Additionally, NC-DWQ's current policy does not require mitigation for buffer impacts if
they do not exceed 1 /3 acre per buffered channel tributary. Because the proposed buffer
impacts resulting from the project do not exceed the aforementioned threshold
(9,983 ft.2 or 0.229 acres), buffer mitigation should not be required. Because the
proposed sewer line corridor will cross the riparian buffer perpendicularly and is less than
co

Quality. This form should not be used if you are requesting an Individual 404 Permit or Individual 401
Water Quality Certification. The USACE Individual Pen-nit application form is available online at
http://www.saw.usace.army.mil/wetlands/Penn 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 at the end 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 detennine 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 some 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 (919) 733-1786.
Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is also 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 the last page of this application).

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.htmi. 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.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
inforination 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 Town of Cary originally required two roadway crossings over the channel where proposed
impacts will occur in order to preserve connectivity within the site-despite our client's
wishes-who understood that the two crossings conflicted with avoiding and minimizing
unnecessary impacts to wetlands/waters of the U.S. Thus, William Barker (our client), S&EC,
and aproject engineer from CH Engineering met with Bob Zarzecki of NC-DWQ in January to
discuss the crossing requirement. After this meeting the project's land planner and en iineer
were able to convince Cary to drop one of the required roadway crossings, leaving the one
proposed in this application which is necessary to access high ground in the northeastern portion
of the property. Additionally DOT has relaxed the minimum turn radius requirement for the
extension of Alphawood Drive (see impact map) in order to minimize Neuse River buffer
impacts. The proposed road crossing (Impact 1) has been designed to cross the stream channel at
a perpendicular angle to minimize impacts. The proposed sewer line crossing (Impact 2) also
has been designed to cross the stream, wetland area, and buffer perpendicularly to minimize
impacts.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 21-1 .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 7 of 12
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
Pennits, 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 detennining 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/ncwetiands/strmgide.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.
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.
The proposed roadway crossing is necessary in order to access high gEound in the northeastern
portion of the property. This road is an extension of a stubbed road on the western property line,
and crosses the stream perpendicularly, impacting as little channel as possible. The sewer line
crossing is necessary to provide all portions of the property with sanitary sewer access. A large,
contiguous bottomland hardwood forest wetland in the middle of the property has been
completely avoided, as have all other wetlands/waters of the U.S. onsite.
NC-DWQ's current policy does not require mitigation for wetland and stream channel impacts
below 1 acre and 150 linear feet of significant channel. Because the proposed cumulative
impacts resulting from the project total 0.0411 acres (0.011 temporary)/ 105 linear ft. (20 ft.
temporary-i.e. less than 1/3 acre and 150 ft.) wetland or stream channel mitigation should not
be required
Page 8 of 12
Additionally NC-DWQ's current policy does not require mitigation for buffer impacts if they do
not exceed 1/3 acre per buffered channel tributary. Because the proposed buffer impacts
resulting from the project do not exceed the aforementioned threshold
(9,983 ft.2 or 0.229 acres) buffer mitigation should not be required. Because the proposed sewer
line corridor will cross the riparian buffer perpendicularly and is less than 40 ft. wide, it is
considered an "exempt" activity by the Neuse River Basin Riparian Buffer Rules, and should not
require riparian buffer mitigation.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:
Amount of stream mitigation requested (linear feet): 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):-
Amount of Coastal wetland mitigation requested (acres): N/A
IX. Environmental Documentation (DWQ Only)
Does the project involve an expenditure of public funds or the use of public (federal/state/local)
land?
Yes ? No
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at (919) 733-5083 to review current thresholds for environmental documentation.
Yes ? No ?
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
N/A
Page 9 of 12
map, whether or not impacts arc 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 Neuse )?
Yes ® No ? If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* Impact
(square feet) Multiplier Required
Mitigation
1 6,291 3.0 N/A
2 3,692 1.5 N/A
Total 9,983 N/A
Zone I extends out 30 tect perpcndficular trom near bank of channel; /.one L 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.
XI. Stormwater (DWQ Only)
Describe impervious acreage (both existing and proposed) versus total acreage on the site.
Discuss stormwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
Impervious acreage on the site is not expected to exceed 30%, therefore, a stormwater_plan
should not be required. However, the site stormwater plan is enclosed with this application.
XII. Sewage Disposal (DWQ Only)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Connection to an existing sanitary sewer easement
Page 10 of 12
XIII. Violations (DWQ Only)
Is this site in violation of DWQ Wetland Rules (I 5A NCAC 21-I .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: The Park At Langston. Creek Crossing
May. 23 2002 10:40AM P2
This memo is to confirm that the proposed lots 1 through 20 at Park at Langston, which are located
on proposed Tributary Dr. and north east of the proposed creek crossing are landlocked unless the
extension of Alphawood Dr, is allowed. Proposed Tributary Dr. does not extend past our project.
There is a reserved right-of-way and not a dedicated right-of-way north of the termination of
Tributary Dr. on our site. Please be advised that a reserved right-of-way means that the Ownership
of this particular right-of way is still held by the original developer. ,Also, there is a 50 ft. Colonial
Pipe line right-of-way carrying three major gas transmission lines within the reserved right-of-way.
The extension of Alphawood Dr. will be the only means of accessing the area north east of the
proposed creek crossing.
If you need additional information, please do not hesitate to let me know.

Dear Mr. Cooper:
This letter is being sent to serve as confirmation of your buffer determination at the project referenced by
the Raleigh Regional Office as NBRRO 01-199. The features represented on the Wake County Soils and
the USGS Lake Wheeler and Apex Quad maps were evaluated to determine their subjectivity to the Neuse
Buffer Rule on July 2, 2001. It was determined that there a total of five features depicted on the property
on the two maps. Three features are subject to riparian buffer protection and are labeled as A, B, and C on
the plat map received August 10, 2001.
This letter only addresses the applicability of the Neuse River Basin: Nutrient Sensitive Waters Management
Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code T15A:02B.0233
(NCAC 0233). For information on wetlands and other impacts, please contact someone at the Central Office
at 733-1786. Thank you for your attention to this matter and if this Office can be. of any assistance or if you
have additional questions, please do not hesitate to contact us.

RE: Park at Langston S/D
John,
Please review the attached plan. They are required by Wake Co. to put in Crossing "A" and by the Town of Cary to put in Crossing
"B". The Town has written a letter referencing their new (?) connectivity ordinance. They have redesigned from the original
alignments to the proposed alignments per S&EC's recommendations. The proposed alignments have less stream impact because they
cross at straight sections of the stream and not meandering sections. Jim with S&EC said the stream being crossed is an intermittent
stream. The stream is on the soil survey but not USGS. Mitchell has confirmed buffers but no perennial calls. Total impacts for both
crossings will be kept below 150 feet. They told me that they're looking like 50 feet and 60 feet, but couldn't make any promises.
Please review the attached information and let me know if you have any immediate objections. They'll be sending in a PCN most
likely this week.
Thanks,
Bob

Thanks for the quick reply. I'm planning on going ahead and sending in
the application as soon as I get impact maps in from the engineer (which
hasn't really been resolved yet)-hopefully by Friday.
Thanks again for meeting with us, and sorry we lingered about so long!
Jim

Jim,
John's first reaction was to avoid the larger crossing (the one you did
not know the name of) and cul-de-sac both ends. I told him that this
crossing was required by both the County and Cary. I would recommend
sending the PCN in as soon as possible to get the review process
started. We may want to get all parties involved to meet, but go ahead
and send it in so we can get started.

Wake County
Mr. William Barker
1401 Sunday Drive, Suite 166
Raleigh, NC, 27607
APPROVAL of 401 Water Quality Certification and Neuse River Buffer Rules with Additional Conditions
Dear Mr. Barker:
You have our approval, in accordance with the attached conditions, to place fill in 0.041 acre of wetlands and 105 linear feet of
intermittent streams and to impact 9,983 square feet of protected Neuse Buffers in order to construct road and sewerline crossings
associated with the Park at Langston subdivision in Wake County, as described in your application received by the Division of Water
Quality on May 24, 2002, and in additional correspondence received June 26 2002, July 18 2002 and July 29, 2002. After reviewing your
application, we have determined that this fill is covered by General Water Quality Certification Numbers 3374 and 3362, which can be
downloaded from our web site at http://h2o.enr.state.nc.us/ncwetlands . This Certification allows you to use Nationwide Permit Numbers
12 and 39 when issued by the U.S. Army Corps of Engineers. This approval is also valid for the Neuse River Buffer Rules (15A NCAC 2B
.0233). In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not limited
to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the
accompanying 404 permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your project, you must
notify us in writing and you may be required to send us a new application for a new certification. If the property is sold, the new owner
must be given a copy of the Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland
fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506
(h). For this approval to be valid, you must follow the conditions listed in the attached certification as well as the additional conditions
listed below:
1. An additional condition is that stormwater shall be directed to diffuse flow at non-erosive velocities through the protected stream
buffers;
2. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas within
50 feet of all streams and ponds. These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of
the 404 Permit (whichever is later). A sample deed notification format can be downloaded from the 401 /Wetlands Unit web site at
http://h2o.enr.state.nc.us/ncwetlands .
3. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401 Certification
has been completed.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60 days
of the date that you receive this letter. 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 6714, Raleigh, N.C. 27699-6714. This certification and its conditions
are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any
questions, please call Steve Mitchell or Debbie Edwards in our Raleigh Regional Office at 919-571-4700 or Cyndi Karoly in the Central
Office at 919-733-9721. Questions regarding stormwater should be directed to Todd St. John at 919-733-9584.

S&EC Project no.: 5968
DWQ Project no.: 020831
Dear Mr. Dorney,
In reference to your letter dated July 10th, 2001 (received by S&EC on July 16th, 2002-
see attached), our client, Barker Realty, does not intend to withdraw the 401-Water
Quality Certification application and Neuse River Buffer Compliance request for the Park
at Langston.
As requested in NC-DWQ's initial correspondence regarding the project (see attached
letter dated June 4th, 2002), S&EC forwarded information provided by the project
engineer (CH Engineering) to address stormwater discharge/diffuse flow through buffers.
Since this information was determined to be inadequate by NC-DWQ, the project
engineer (CH Engineering) will resubmit the requested calculations and plans
demonstrating that diffuse flow through the buffers will be achieved directly to NC-
DWQ. Therefore, please do not consider the application withdrawn-rather, it should be
considered to be on administrative hold pending the receipt of additional information that
will allow the continued processing of the permit application.
Please call me if you require any additional information, or email me at

The Division of Water Quality has reviewed your response, received June 26, 2002, to our request for
additional information regarding your application for a 401 Certification and Neuse Buffer Rules Approval, received May
24, 2002, for the subject project.
In previous correspondence dated June 4, 2002, this Office requested that you provide plans and calculations
to show that diffuse flow of stormwater would be provided in the Neuse Riparian Buffers in compliance with 15A NCAC 2B
.0233 (5). Only one plan page was provided that indicated some kind of level spreader for one of the five listed stormwater
outlets. No calculations were provided to show that this level spreader is adequately sized, and no topographic
information was provided to show that the slopes were adequate to accept the flow. No calculations or (readable) plans
were provided for the other outlets. This information was needed by DWQ in order for us to decide whether this project is
approvable.
Since the requested information was not provided, we are hereby returning the subject application. As such,
this application is withdrawn. Should you decide to reapply you must provide seven copies of an application and
supporting documentation as well as the appropriate fee.
If you have any questions please contact Todd St. John at 919-733-9584 or John Dorney at 919-733-9646 if

Dear Mr. Dorney,
In response to your letter dated June 4th, 2002 (see attached), enclosed is the approved
wetland delineation for the Park at Langston as well as calculations provided by the
project engineer regarding diffuse flow through the Neuse River Riparian Buffers.
It should be noted that in the preconstruction notification form (PCN) originally
submitted, under Item XI (which discusses stormwater), it was erroneously mentioned
that calculation tables provided by the project engineer were included in the application.
These tables were not included in the application submitted to NC-DWQ. However, as
indicated in the attached calculation tables provided here by the project engineer
addressing stormwater issues, impervious surface acreage is estimated at 15 %, well
below the established 30 % threshold requiring stormwater management plans.
Therefore, we do not believe that a stormwater management plan should be required by
NC-DWQ.

RE: Nationwide Permits 12 and 39, 401-Water Quality Certification, and Neuse
River Buffer Rules Compliance Request
Park at Langston
Cary, Wake County, North Carolina
UTM coordinates: 703500"'E 39, 39750"'N
S&EC Project #: 5968
Dear Mr. Dorney and Ms. Jones,
On behalf of William Barker, (property owner), we hereby request authorization from the
US Army Corps of Engineers to use Nationwide Permits 12 and 39 for the subject project
to cover permanent impacts to stream channels and wetlands. We also request written
concurrence from the NC Division of Water Quality (NC-DWQ) that the project
complies with the 401-Water Quality Certification associated with Nationwide Permit 39,
and that it complies with the Neuse River Riparian Buffer rules. A Pre-construction
Notification Application (PCN) is attached, which includes an agent authorization form.
S&EC performed a Neuse River Buffer evaluation for the site in fall 2000, and a detailed
wetland delineation in April 2002, which was submitted to the USACE for approval on
May 20th, 2002. Data forms for the delineation are attached. NC-DWQ confirmed
S&EC's Neuse River Buffer evaluation (NBRRO 01-199-see attached).
The proposed project, which consists of a residential subdivision, is located east of West
Lake Rd. (SRI 387), west of Bells Lake Rd. (SR 1386), approximately one mile south of
Ten-Ten Rd. (SR 1010) near Cary, Wake County, NC. Please refer to the USGS site
snap. The property comprises approximately 32 acres, and is in the Neuse River Basin.
Approximately 0.003 acres (1,278 ft.2) of jurisdictional wetlands and 85 linear ft. of
stream channel will be impacted for a roadway crossing (Impact 1-see impact maps)
under Nationwide Permit 39 (totaling 0.03 acres/85 linear ft.). Approximately 9,983 ft.2
(zone 1: 6,291 ft. 2, zone 2: 3,692 ft.2) of Neuse River Buffer will be impacted by the

r. r, - May 24th, 2002
proposed roadway crossings (Impact 1). Approximately 0.011 acres (495 ft.2) of
jurisdictional wetlands and 20 linear ft. of stream channel will be temporarily impacted
under NWP 12 (Impact 2-see impact maps). Total proposed impacts are 0.0411 acres
(0.011 temporary)/ 105 linear ft. (20 ft. temporary).
The Town of Cary originally required two roadway crossings over the channel where
proposed impacts will occur in order to preserve connectivity within the site-despite our
client's wishes-who understood that the two crossings conflicted with avoiding and
minimizing unnecessary impacts to wetlands/waters of the U.S. Thus, William Barker
(our client), S&EC, and a project engineer from CH Engineering met with Bob Zarzecki
of NC-DWQ in January to discuss the crossing requirement. After this meeting, the
project's land planner and engineer were able to convince Cary to drop one of the
required roadway crossings, leaving the one proposed in this application, which is
necessary to access high ground in the northeastern portion of the property. Additionally,
DOT has relaxed the minimum turn radius requirement for the extension of Alphawood
Drive (see impact map) in order to minimize Neuse River buffer impacts.
It is important to note that the road shown entering the site on the northern property line
is not yet constructed, and is a reserved road right-of-way-not a dedicated right-of=way.
Thus, the road right-of-way is still owned by the adjacent site's developer. Additionally,
there is a gas line easement parallel to the northern property line immediately adjacent to
the property.
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 of waters of the US when impacts
exceed the requirements for notification. The proposed roadway crossing is necessary in
order to access high ground in the northeastern portion of the property. This road is an
extension of a stubbed road on the western property line. Both the roadway and sewer
line crossing, as evinced by the site plan, have been designed to cross wetland areas and
the stream channel perpendicularly. A large, contiguous bottomland hardwood forest
wetland in the middle of the property has been completely avoided, as have all other
wetlands/waters of the U.S. onsite.
NC-DWQ's current policy does not require mitigation for wetland and stream channel
impacts below 1 acre and 150 linear feet of significant channel per project. Because the
proposed cumulative impacts resulting from the project total 0.0411 acres (0.011 acres
temporary)/ 105 linear ft. (20 ft. temporary), project impacts are below the
aforementioned thresholds, and S&EC believes that neither wetland nor stream channel
mitigation should be required
Additionally, NC-DWQ's current policy does not require mitigation for buffer impacts if
they do not exceed 1/3 acre per buffered channel tributary. Because the proposed buffer
impacts resulting from the project do not exceed the aforementioned threshold
(9,983 ft.z or 0.229 acres), buffer mitigation should not be required. Because the
proposed sewer line corridor will cross the riparian buffer perpendicularly and is less than
40 ft. wide, it is considered an "exempt" activity by the Neuse River Basin Riparian
Buffer Rules, and should not require riparian buffer mitigation.
Please call me if you require any additional information, or email me at

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 pen-nit applies to your project, please go to the
USACE website at http://www.saw.usace.anny.mil/wetlands/regtour.htiu, or contact one of the field
offices listed at the end 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 some 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 (919) 733-1786.
Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is also 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 the last page of this application).
Page I of 12
LAMA Coordination - If the project occurs in any of North Carolina's twenty coastal counties (listed on
the last page of this application) the applicant should also contact the North Carolina Division of Coastal
Management (DCM) at (919) 733-2293. DCM will determine whether or not the project involves a
designated Area of Environmental Concern, in which case DCM will act as the lead pennitting agency.
In such cases, DCM will require a Coastal Area Management Act (CAMA) Permit and will coordinate
the 404/401 Permits.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office (addresses are listed at the end of this
application). Upon receipt of an application, the USACE will detennine 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.army.mil/wetlands/nwpfinalFedReg.pdf.
Processing times vary by pen-nit 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.

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.):
Size of watershed draining to pond: Expected pond surface area:
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 Town of Cary originally required two roadway crossings over the channel where proposed
impacts will occur in order to preserve connectivity within the site-despite our client's
wishes-who understood that the two crossings conflicted with avoiding and minimizing
unnecessary impacts to wetlands/waters of the U.S. Thus William Barker (our client), S&EC,
and a project engineer from CH Engineering met with Bob Zarzecki of NC-DWQ in January to
discuss the crossing requirement. After this meeting, the project's land planner and engineer
were able to convince Cary to drop one of the required roadway crossings, leaving the one
proposed in this application, which is necessary to access high ground in the northeastern portion
of the property. Additionally, DOT has relaxed the minimum turn radius requirement for the
extension of Alphawood Drive (see impact map) in order to minimize Neuse River buffer
impacts The proposed road crossing (Impact 1) has been designed to cross the stream channel at
a perpendicular angle to minimize impacts The proposed sewer line crossing (Impact 2) also
has been designed to cross the stream wetland area and buffer perpendicularly to minimize
impacts.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
Page 7 of 12
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/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.
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.
The proposed roadway crossing is necessary in order to access high ground in the northeastern
portion of the property. This road is an extension of a stubbed road on the western property line,
and crosses the stream perpendicularly, impacting as little channel as possible. The sewer line
crossing is necessary to provide all portions of the property with sanitary sewer access. A large,
contiguous bottomland hardwood forest wetland in the middle of the property has been
completely avoided as have all other wetlands/waters of the U.S. onsite.
NC-DWQ's current policy does not require mitigation for wetland and stream channel impacts
below 1 acre and 150 linear feet of significant channel. Because the roposed cumulative
impacts resulting from the project total 0.0411 acres (0.011 temporary)/ 105 linear ft. (20 ft.
temporary-i a less than 1/3 acre and 150 ft) wetland or stream channel mitigation should not
be required
Page 8 of 12
Additionally NC-DWQ's current policy does not require mitigation for buffer impacts if they do
not exceed 1/3 acrc per buffered channel tributary. Because the proposed buffer impacts
resulting from the project do not exceed the aforementioned threshold
(9,983 ft 2 or 0.229 acres) buffer mitigation should not be required. Because the proposed sewer
line corridor will cross the riparian buffer perpendicularly and is less than 40 ft. wide it is
considered an "exempt" activity by the Neuse River Basin Riparian Buffer Rules, and should not
require riparian buffer mitigation.
Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http_//h2o.enr.state.nc.us/wry/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
IX. Environmental Documentation (DWQ Only)
Does the project involve an expenditure of public funds or the use of public (federal/state/local)
land?
Yes ? No
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)9.
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at (919) 733-5083 to review current thresholds for environmental documentation.
Yes ? No ?
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
Page 9 of 12
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 Neuse )?
Yes ® No ? If you answered "yes", provide the following infortation:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* Impact
(square feet) Multiplier Required
Mitigation
1 6,291 3.0 N/A
2 3,692 1.5 N/A
Total 9,983 N/A
* Zone 1 extends out 30 feet perpendicular from near bank of channel; Gone 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.
N/A
XI. Stormwater (DWQ Only)
Describe impervious acreage (both existing and proposed) versus total acreage on the site.
Discuss stonnwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
Impervious acreage on the site is not expected to exceed 30% (see attached calculation tables
from project engineer); therefore a stormwater plan should not be required.
X1I. Sewage Disposal (DWQ Only)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Connection to an existing sanitary sewer casement
Page 10 of 12
X111. Violations (DWQ Only)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules`?
Yes ? No
Is this an after-the-fact permit application?
Yes ? No
XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).

Re: The Park At Langston Creek Crossing
May. 23 2002 10:40AII P2
This memo is to confirm that the proposed lots 1 through 20 at Park at Langston, which are located
on proposed Tributary Dr. and north east of the proposed creek crossing are landlocked unless the
extension of Alphawood Dr. is allowed. Proposed Tributary Dr. does not extend past our project.
There is a reserved right-of-way and not a dedicated right-of-way north of the termination of
Tributary Dr. on our site. Please be advised that a reserved right-of-way means that the Ownership
of this particular right-of way is still held by the original developer. Also, there is a 50 ft. Colonial
Pipe line right-of-way carrying three major gas transmission lines within the reserved right-of-way.
The extension of Alphawood Dr. will be the only means of accessing the area north east of the
proposed creek crossing.
If you need additional information, please do not hesitate to let me know.

Dear Mr. Cooper:
This letter is being sent to serve as confirmation of your buffer determination at the project referenced by
the Raleigh Regional Office as NBRRO 01-199. The features represented on the Wake County Soils and
the USGS Lake Wheeler and Apex Quad maps were evaluated to determine their subjectivity to the Neuse
Buffer Rule on July 2, 2001. It was determined that there a total of five features depicted on the property
on the two maps. Three features are subject to riparian buffer protection and are labeled as A, B, and C on
the plat map received August 10, 2001.
This letter only addresses the applicability of the Neuse River Basin: Nutrient Sensitive Waters Management
Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code T15A:02B.0233
(NCAC 0233). For information on wetlands and other impacts, please contact someone at the Central Office
at 733-1786. Thank you for your attention to this matter and if this Office can be.of any assistance or if you
have additional questions, please do not hesitate to contact us.

Jim,
John's first reaction was to avoid the larger crossing (the one you did
not know the name of) and cul-de-sac both ends. I told him that this
crossing was required by both the County and Cary. I would recommend
sending the PCN in as soon as possible to get the review process
started. We may want to get all parties involved to meet, but go ahead
and send it in so we can get started.
