III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.
1. Name of project: Downing Village
2. T.I.P. Project Number or State Project Number (NCDOT Only):
3. Property Identification Number (Tax PIN): 074516749648,074516834762& 074501484496
4. Location
County: Wake Nearest Town: Morrisville
Subdivision name (include phase/lot number):_ Downing Village
Directions to site (include road numbers/names, landmarks, etc.):_ The project site is located
north of Morrisville Carpenter Road (SR 3014), approximately 3,500 feet east of the
intersection of Morrisville Road and Davis Drive (SR 1613).
Site coordinates (For linear projects, such as a road or utility line, attach a sheet that
separately lists the coordinates for each crossing of a distinct waterbody.)
Decimal Degrees (6 digits minimum): 035°49'35.13" ON 078°50' 16.77" °W
6. Property size (acres): ± 58.47 Acres
7. Name of nearest receiving body of water: Indian Branch and UT to Indian Branch.
8. River Basin: Neuse
(Note - this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.enr.state.ne.us/adniin/maps/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The site is primarily an undeveloped, wooded tract. The
southeastern portion (single-family) of the site is currently being cleared to connect to
adjacent properties, however no impacts to jurisdictional areas or buffers have occurred. An
Page 2 of 9
existing power line easement crosses the site and a sewer easement also exists on the
property.
Describe the overall project in detail, including the type of equipment to be used: The
proposed project is a single-family and town home residential subdivision with the typical
utilities (i.e. sewer, water, electric, etc.). A proposed water line will temporarily impact 21
linear feet of stream as well as 0.049 acre of Neuse River riparian buffers. Downing Village
also proposes a footbridge crossing of Indian Branch as part of the town's reg enway system,
which will impact 0.093 acre of Neuse River riparian buffers and an open bottomed bridge
road crossing which will impact 0.2 acre of Neuse River riparian buffers. Neither bridged
crossing will result in the impact of any iurisdictional waters. Heavy machinery typically
used for land clearing and road construction will be used for this project.
10. Explain the purpose of the proposed work: The purpose of the proposed water line is to
provide water to the homes in the northwest part of the property. The purpose of the open
bottomed bridge is to provide access to the homes in the northwest pat of the property. The
reg enway crossing is necessary to incorporate the new development into the town's existing
greenway network.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. Ms. Deborah Edwards with the NC-DWQ visited the site on July 24,
2002 to determine the starting point of riparian buffers (NBRRO 02-152). On December 11,
2003, Ms. Andrea Wade with the USACE made a jurisdictional determination on the site (AID
200320868).
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
No future impacts are expected at this time.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
Page 3 of 9
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: The proposed water line
(impact 3) will temporarily impact 21 linear feet of stream as well as 0.049 acre (Z1-1302
s.f_, Z2-812 s.f) of Neuse River riparian buffers and will meet all conditions of General
Certification 3374, therefore written 401 approval is not requested. The proposed arch-
culvert road crossing (impact 2 will impact 0.2 acre (Z1-5369 s.f. Z2-3544 s f, of Neuse
River riparian buffers. The proposed reg enway bridge crossing (impact 1) will impact 0.028
acre _(Z1-860 s.f., Z2-355 s.f.) ofNeuse River riparian buffers.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary
impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam
construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib
walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed,
plans and profiles showing the linear footprint for both the original and relocated streams
must be included. To calculate acreage, multiply length X width, then divide by 43,560.

7. Isolated Waters
Do any isolated waters exist on the property? ? Yes ® No
Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
No impacts exist on the site and no impacts to isolated waters are proposed.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): n/a
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): n/a
Current land use in the vicinity of the pond: n/a
Size of watershed draining to pond: n/a Expected pond surface area: n/a
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 applicant requested a
detailed wetland and Neuse River Buffer delineation of waters on-site prior to site plan
development in order to determine the extent and location of wetlands, streams, and buffers. The
detailed wetland delineation determined that no wetlands existed within the proposed impact
locations The proposed water line is necessary to provide water to the homes in the northwest
corner of the property. The applicant initially proposed placing the waterline crossing within the
road crossing's footprint in an effort to avoid additional buffer impacts however, the town will
not allow the waterline to be suspended beneath the proposed road crossing and will not allow
Page 5 of 9
the waterline to be installed beneath the road crossing for access and maintenance purposes so
the water line must be placed adjacent to the proposed road crossing. The water line will cross
the intermittent stream at an approximately perpendicular angle to minimize the impacts during
construction. No wetlands exist within the proposed impact areas. The impacts to buffers
resulting from the proposed waterline, road crossing, and rely crossing were minimized by
crossing at approximately perpendicular angles.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, 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 NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.ne.us/ncwetiands/strmgidc.htm].
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The jurisdictional areas have been avoided to the maximum ''extent practicable.
Typically, temporary impacts due to a utility crossing do not require mitigation, therefore no
mitigation is proposed.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
Page 6 of 9
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wM/index.litm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): 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 (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes El No
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No ?
3. If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
1. Will the project impact protected riparian buffers identified within 15A NCAC 213 .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
213 .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify V Yes ® No ?
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multipliers.

3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. N/A No mitigation is required because the
proposed impacts are considered to be either "exempt" or "allowable" activities.
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. The proposed impervious surface area for the
Downing Villav-e protect will total 38.83%. The stormwater plan is depicted on the attached
grading map but because a 401-permit is not required DWQ approval of the stormwater plan is
not required. The site does however have to meet the local municipality's stormwater
requirements and will also have diffuse flow devices (see attached worksheets) that comply with
DWG's standards.
Page 8 of 9
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
The proposed subdivision will tie into an existing sewer line on the property.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application? Yes ? No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes El No ?
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.ne.us/ncwetlands. If no, please provide a short narrative description: We
have reviewed the "DRAFT Internal Policy, Cumulative impacts and the 401 Water Quality
Certification and Isolated Wetland Programs" document prepared by the NC Division of Water
Quality on October 3, 2002, version 1.6. The draft states that most residential subdivisions are
unlikely to cause cumulative impacts. Downing Village Subdivision does not meet any of the
three criteria of private projects that can clearly result in cumulative impacts. We anticipate that
you will advise us if a qualitative or quantitative impact analysis is required.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).

REQUEST FOR MORE INFORMATION
Dear Mr. Berger:
On September 29, 2005, the Division of Water Quality (DWQ) received your application dated
September 29, 2005, to impact 21 linear feet of streams and 12,242 square feet of Neuse River basin
riparian buffers to construct the proposed waterline delivery, bridge to the northwest portion of the subject
property and greenway connection to the town's existing greenway network. The DWQ has determined
that your application was incomplete and/or provided inaccurate information as discussed below. The
DWQ will require additional information in order to process your application to impact protected
wetlands and/or streams on the subject property. Therefore, unless we receive the additional information
requested below, we will have to move toward denial of your application as required by 15A NCAC 2H
.0506 and will place this project on hold as incomplete until we receive this additional information.
Please provide the following information so that we may continue to review your project.
Additional Information Requested:
Please indicate the diffuse flow provisions on the site plan.
2. Please provide the details and calculations for the proposed level spreaders.
3. An approved stormwater plan is required by the DWQ per 15A NCAC 2B.0233(5), and as
described in our April 14, 2004 correspondence to D.R. Horton requesting more information.
Please respond within three weeks of the date of this letter by sending this information to me in writing
and Eric Kulz of the DWQ Raleigh Regional Office. If we do not hear from you within three weeks, we
will assume that you no longer want to pursue this project and we will consider the project as withdrawn.
This letter only addresses the application review and does not authorize any impacts to wetlands, waters
or protected buffers. Please be aware that any impacts requested within your application are not
authorized (at this time) by the DWQ. Please call Ms. Cyndi Karoly or Mr. Ian McMillan at 919-733-
1786 if you have any questions regarding or would like to set up a meeting to discuss this matter.

NOTICE OF WITHDRAWL
Dear Mr. Spivey:
On April 6, 2004, you requested a 401 Water Quality Certification from the Division of Water
Quality (DWQ) for your project. We wrote to you on April 14, 2004 discussing concerns that we
have regarding the design of the project and stating that it would be placed on hold for three weeks
giving you time to address DWQ's concerns. As of today, DWQ has not received a response to this
request. Therefore, your file is hereby considered withdrawn and will not be reviewed until DWQ's
earlier concerns are addressed. Once you have collected sufficient information to have a complete
application (please see our April 14, 2004 letter for the missing information), you will need to reapply
for DWQ approval. This includes submitting a complete application package with the appropriate
fee.
Please be aware that you have no authorization under Section 401 of the Clear Water Act for this
activity and any work done within waters of the state would be a violation of North Carolina General
Statuses and Administrative Code. Please call Mr. Ian McMillan at 919-715-4631 if you have any
questions or concerns.

Sean - you need to note that both Dorney and I have been getting yanked around about an OAH hearing much of this
past week, not to mention spontaneous meetings by DOC and scrambling due to losing yet another employee (yes, to
S&EC). Sorry, but the judge is our boss and we will get to your client in order. Ian briefly mentioned your project
during my brief visit to the office today. He has pulled the file. Please note
that I have not looked at it yet.
He mentioned t4 perhaps you were looking into whether the two referenced retention devices are indeed available
to your client for use, and if there is sufficient capacity to handle the additional discharges.
Yes. The project has been given permission to discharge into the adjacent properties' stormwater, by the Town of
Cary and the adjacent property owners.
Without these devl ices, the two discharges would not have diffuse flow provisions, correct?
Correct. However, again it is our interpretation that "diffuse flow" should not be required since we arc discharging
to an existing stormmmwater conveyance system approximately 500 feet from the closest regulated buffer.
So you're proposing use of the retention devices in lieu of the diffuse flow measures required?
Not really becausQ Nve don't feel that the diffuse flow measures should be required. Thcy just wanted to give
something back to help John feel more comfortable with the approval. The stormwater devices are required by the
Town of Cary.
I think there's also, a matter of semantics involved here - diffuse flow measures are actually one of many types of
stormwater control. John has not asked you to develop a full-blown stormwater management plan and ponds for the
property, has he?
No, but the project no longer requires written concurrence from DWQ for GC3402 (because the current plans use
an open bottom culvert) and as such does not require compliance with Condition No. 4 of GC3402 ; and because
they are dischargi w to existing conveyances "diffuse flow" should not be an issue either.
i`
We'll try to pay attention to your project - god help me - if I don't have any more bonfires added or staff lost this
week.
Thanks. Any help you could provide would be greatly appreciated. The current interpretation that we've been
,,iven doesn't seen, to be consistent with previous reviews and interpretations.

To: <John.Dorneva.ncmail.net>
John:
The client isipressing us for an approval for the Downing Village
Project that you emailed me back about yesterday (DWQ Project
#2004-0531).
The project is requesting a buffer authorization certificate for a road
crossing thatlproposes the use of a bottomless arch culvert bridge (no
stream impacts). (Also, there is a NWP 12 that the USACE has issued an
approval for that meets all of the conditions of GC 3374 and does not
require prior written concurrence from DWQ.)
I understand that the only thing that is holding up your approval is the
stormwater treatment information that you requested in two locations.
After our meeting in your office in February we realized that the
stormwater inithese two locations discharges into existing adjacent
stormwater networks. We most recently responded to your request on
February 28th and I understand that it's on your pile of things to do
and that you were hoping to get to it soon.
The client neeeds an approval by Friday. Is this possible?
I'm not trying to be difficult, but this thing really has been dragging
on for months!. As you know, our position is that the two discharge
locations in question are not regulated under the Diffuse Flow provision
of the Neuse Buffer Rule given that they are to existing stormwater
conveyances at least t 500 feet from the closest buffer. However, we
believe that iie have provided the adequate treatment that you requested
anyway. !
Anything that you could do to help expedite this approval process would
be much appreciated.
Thanks
Sean

Downing Village
Wake County, North Carolina
Dear Mr. Dorney and Mr. McMillan:
This letter is in response to your letter dated February 2, 2006 (copy attached), which requested additional
information for the proposed Downing Village Residential Development. The two primary areas of your
stormwatcr concern arc shown on the attached inset maps. Upon review of the plans, it was discovered that
these two areas are draining to existing stormwater facilities/networks on adjacent sites.
The Dry Detention Basin on the southern property line is draining into an existing Dry Detention Basin (see
attached map) and is greater than 800 feet to the nearest buffered drainage.
The stormwater outlet along the eastem property line outlets an underground detention device. The outlet
releases to a grassed swale that drains to an existing offsite stormwater network that exists to the east of the
property.
This information was not presented to DWQ iti the earlier submittals. It has been our understanding that
tying into existing stormwater does not require DWQ approval thereby not requiring stormwater approval
for this site. The diffuse flow provisions will be met on site using the level spreaders previously described.
We then request that the Neuse Buffer Compliance letter be issued.
Please call if you have any questions or require further explanation.
Sincerely
d
Sean Clark

The Division received a response to our October 11, 2005 letter on December 12, 2005
from Mr. Sean Clark of Soil and Environmental Consultants. Unfortunately, this response did
not address our questions about the proposed stormwater management plan for this site that is

unable to talk directly mainly due to my schedule although we have traded voice mails. I think
that a meeting with your stormwater engineer, will be needed to address our questions about

Re: Reply to the Division of Water Quality's 02/02/2006 request for additional information
Downing Village
Wake County, North Carolina
Dear Mr. Dorney and Mr. McMillan:
This letter is in response to your letter dated February 2, 2006 (copy attached), which requested additional
information for the proposed Downing Village Residential Development. The two primary areas of your
stormwater concern are shown on the attached inset maps. Upon review of the plans, it was discovered that
these two areas are draining to existing stormwater facilities/nctworks on adjacent sites.
The Dry Detention Basin on the southern property line is draining into an existing Dry Detention Basin (see
attached map) and is greater than 800 feet to the nearest buffered drainage.
The stormwater outlet along the eastern property line outlets an underground detention device. The outlet
releases to a grassed Swale that drains to an existing of(site stormwater network that exists to the east of the
property.
This information was not presented to DWQ ft the earlier submittals. It has been our understanding that
tying into existing stormwater does not require DWQ approval thereby not requiring stormwater approval
for this site. The diffuse flow provisions will be met on site using the level spreaders previously described.
We then request that the Neuse Buffer Compliance letter be issued.
Please call if you have any questions or require further explanation.
Sincerely
Scan Clark

Dear Mr. Berger:
RE: Stormwater management issues for Downing Village
DWQ # 20040531
Wake County
William G. Ross, Jr., Secretary
Alan W. Klimek, P.E., Director

The Division received a response to our October 11, 2005 letter on December 12, 2005
from Mr. Sean Clark of Soil and Environmental Consultants. Unfortunately, this response did
not address our questions about the proposed stormwater management plan for this site that is
required under the Neuse River Buffer rules (15A NCAC 2B ,0233). Mr. Clark and I have been
unable to talk directly mainly due to my schedule although we have traded voice mails. I think
that a meeting with your stormwater engineer. will be needed to address our questions about
stormwater management for this site. Please have your engineer and Mr. Clark call or email me
with possible times to meet to discuss this issue so we can get it resolved and issue the
approval for this project. I can be reached at 919-733-9646 or via email at
iohn.dorney(a-)-ncmail.net. Until this meeting is held and the additional information received, this
project shall remain on hold as incomplete.
Thank you in advance for your help in resolving this matter.

Ian:
We talked about this one briefly. Greater than 30% impervious (38.83%). Request For
More Info letter dated 12/12/05 says "An approved stormwater plan is required by the
DWQ per 15A NCAC 2B .0233(5)". This section of the rule simply requires diffuse
flow. They provided plans showing level spreaders and detention basins, and also
provided level spreader worksheets in their response.
I can't see where we have the "hook" to require a stomwater plan and notrogen
removal. For NW 12, the corresponding GWQC is 3374, which does not have the
stormwater condition. Cyndi pretty much agreed with me. John, however, mentioned
that we did have the authority under the buffer rules to require nitrogen removal
and an approved stormwater plan. You may want to consult John and Cyndi and let them
work it out.
I have no issues with the impacts (extremely minimal), and recommend issuance once
the stormwater thing is worked out.
My comments on BIMS.

REQUEST FOR MORE INFORMATION
Dear Mr. Berger:
On September 29, 2005, the Division of Water Quality (DWQ) received your application dated
September 29, 2005, to impact 21 linear feet of streams and 12,242 square feet of Neuse River basin
riparian buffers to construct the proposed waterline delivery, bridge to the northwest portion of the subject
property and greenway connection to the town's existing greenway network. The DWQ has determined
that your application was incomplete and/or provided inaccurate information as discussed below. The
DWQ will require additional information in order to process your application to impact protected
wetlands and/or streams on the subject property. Therefore, unless we receive the additional information
requested below, we will have to move toward denial of your application as required by 15A NCAC 2H
.0506 and will place this project on hold as incomplete until we receive this additional information.
Please provide the following information so that we may continue to review your project.
Additional Information Requested:
Please indicate the diffuse flow provisions on the site plan.
2. Please provide the details and calculations for the proposed level spreaders.
3. An approved stormwater plan is required by the DWQ per 15A NCAC 2B.0233(5), and as
described in our April 14, 2004 correspondence to D.R. Horton requesting more information.
Please respond within three weeks of the date of this letter by sending this information to me in writing
and Eric Kulz of the DWQ Raleigh Regional Office. If we do not hear from you within three weeks, we
will assume that you no longer want to pursue this project and we will consider the project as withdrawn.
This letter only addresses the application review and does not authorize any impacts to wetlands, waters
or protected buffers. Please be aware that any impacts requested within your application are not
authorized (at this time) by the DWQ. Please call Ms. Cyndi Karoly or Mr. Ian McMillan at 919-733-
1786 if you have any questions regarding or would like to set up a meeting to discuss this matter.

NOTICE OF WITHDRAWL
Dear Mr. Spivey:
On April 6, 2004, you requested a 401 Water Quality Certification from the Division of Water
Quality (DWQ) for your project. We wrote to you on April 14, 2004 discussing concerns that we
have regarding the design of the project and stating that it would be placed on hold for three weeks
giving you time to address DWQ's concerns. As of today, DWQ has not received a response to this
request. Therefore, your file is hereby considered withdrawn and will not be reviewed until DWQ's
earlier concerns are addressed. Once you have collected sufficient information to have a complete
application (please see our April 14, 2004 letter for the missing information), you will need to reapply
for DWQ approval. This includes submitting a complete application package with the appropriate
fee.
Please be aware that you have no authorization under Section 401 of the Clear Water Act for this
activity and any work done within waters of the state would be a violation of North Carolina General
Statuses and Administrative Code. Please call Mr. Ian McMillan at 919-715-4631 if you have any
questions or concerns.
