DWQ Project # 04-0544,Ver.3
W &R Project #0208o688.o6
Dear Mr. Shaeffer and Ms. Higgins,
On behalf of John Weiland Homes, LLC, we are requesting authorization from the USACE to
use NWP 29 for 49 if of permanent perennial stream impacts and 221 if of unimportant
stream for construction of Phases 4 &5 of the River Run Subdivision. We are also requesting
4o1 authorization for the above mentioned stream impacts, as well as Buffer Authorization
for 13,490 sq ft of riparian buffer impacts (Z1: 7,568 sq ft; Z2: 5,922 sq ft).
The project is ±14.6 acres in size and is located at the southern terminus of Wake Bluff Drive
in the River Run subdivision in Raleigh, Wake County (Latitude: 35.927636 °N; Longitude: -
78.580747 °W)• The project is located in the Neuse River basin and onsite waters drain to
the Neuse River. The Water Quality Classification for the Neuse River is WS- IV;NSW and the
Stream Index Number is: 27420.7). The cataloging unit for the site is 03020201.
Proposed Project
The proposed project consists of the construction of Phases 4 &5 of the River Run
subdivision, which will consist of 29 lots and associated infrastructure (i.e. roads, utilities,
stormwater management, etc.) Please note that this will be the final phases of the River
Run subdivision.

Proiect Histo
The River Run Subdivision was originally permitted in 2004. The Corps issued a NWP 12 &
39 (AID #s 200321366 & 2004420721) for the original River Run subdivision which
authorized 181 if of permanent stream impacts and 98 if of temporary stream impacts. DWQ
issued a 401 WQC and Buffer Authorization (DWQ Project #04-0544) for the River Run
subdivision authorizing 181 if of permanent stream impacts, 98 if of temporary stream
impacts and 31,315 sq ft of buffer impacts. The authorizations required 181 if of stream
mitigation and 1,740 sq ft of buffer mitigation, which was purchased from EEP. Copies of
these permits and mitigation receipt have been provided as an Appendix.
River Run Phases 4 &5 (current project) was issued a 401 WQC and Buffer Authorization
(DWQ Project #04-0544, Ver.3) in October 2oo9 authorizing 203 if of permanent, perennial
stream impacts (181 if previously permitted & 49 if of new impacts), 221 if of permanent
impacts to unimportant, intermittent stream impacts (new impacts) and 38,346 sq ft of
buffer impacts. The 401 WQC required 49 if of stream mitigation. A copy of the previous 401
WQC for the River Run Phases 4 &5 project has been provided as an Appendix.
The Corps issued a NWP 29 in September 2011 (AID# SAW - 2009 - 01115) authorizing 49 if of
important perennial stream impacts. The 221 if of unimportant, intermittent stream
impacts, which were identified in the PCN, were not included in the permit as they were
waived by the Corps and not included in the total cumulative impacts for the River Run
subdivision and mitigation was not required for these impacts. It should be noted that the
221 if of intermittent stream consists of a small channel, which is fed by the outfall for the
stormwater management system of the development to the south. This section of
intermittent stream has very low functional value and the hydrology is controlled entirely by
discharges from the adjacent stormwater management system, which is why the Corps
waived the impacts /mitigation for this feature. The previous NWP 29 required 98 if of
stream mitigation, which was purchased from Forrest Creek Mitigation Bank. A copy of the
previous NWP 29 for River Run Phases 4 &5 has been provided as an Appendix. A copy of the
mitigation payment receipt has also been provided as an Appendix.

Please note that during the previous 401 WQC review process for River Run Phases 4 &5,
DWQ issued a Request for Additional Information, of which Item 6 addressed the issue of
why the riparian buffers stopped at Impact Q, and did not extend along the intermittent
stream at Impact Y. W &R submitted a response, dated September 18, 2oo9, documenting
that a site visit had been previously conducted by NC -DWQ which confirmed that the limits
of buffer subjectivity stopped at the origin of Impact Q, and that the intermittent stream
(Impact Y) was not subject to buffers. The issuance of the previous Buffer Authorization for
the proposed project documents that the intermittent stream (Impact y) was not subject to
buffers.
The Corps NWP 29 and DWQ 401 WQC and Buffer Authorization expired on March 18, 2012,
but are granted an automatic 1 -year extension, making them valid until March 18, 2013.
The River Run Phases 4 &5 was previously permitted as a townhome development, and due
to the downturn of the economy, the authorized impacts were never completed. As a result
of the current real estate market, townhomes are not a desired product in this area of
Raleigh and are not currently selling in the general area. Therefore, the site plan was
revised to convert the project from a townhome development to a single family residential
development. The revision of the design to a single family development resulted in changes
to the road design and stormwater management design, which has resulted in a change in
the previously approved impacts. The major design change in the road construction will
occur at Impact Y. The previous design was for a road crossing in order to provide access to
WITHERS RAVENEL Page 3 of 7
ENGINEERS I PLANNERS I SURVEYORS
WITHERS II RAVEN EL
ENGINEERS I PLANNERS I SURVEYOR5
the uplands on the west side of the stream and for construction of the townhomes on Lots
28 & 29 (old site plans). The design now proposes a cul -de -sac on the eastern side of the
stream at Impact Y, which will provide road frontage for construction of Lots 11, 12 & 13 (new
site plans). The 221 if of unimportant intermittent stream impacts will still be necessary for
construction of single family Lots 11, 12 & 13 rather than the previously approved
townhomes. While the NWP 29 and 401 WQC /Buffer Authorization is valid until March 18,
2013, the revisions to the site plan and impacts resulted in a need to request new
authorizations for the proposed project. The redesign of the site plan will require the same
amount of stream impacts as was previously authorized, but revisions to the stormwater
management plan has resulted in changes to the buffer impacts from what was previously
authorized for the River Run Phases 4 &5 project. Also, please note that the pedestrian trail
and bridge previously authorized at Impact R is no longer required by the City of Raleigh and
will not be constructed.
Proposed Impacts
Stream Impacts
The proposed project will result in 49 if of permanent perennial stream impacts and 221 if of
unimportant intermittent stream impacts, which is the same as was previously approved.
The 49 if of permanent perennial stream impacts will occur from the placement of rip -rap in
the channel below the stormwater outfall in order to dissipate energy and prevent erosion,
which is the same design and impacts as was previously approved.
The previously approved 221 if of unimportant intermittent stream impacts was authorized
for construction of the road crossing and construction of townhomes on Lots 28, 29 & 30
(old site plans). The proposed design for Phases 4 &5 will require 221 if of unimportant
intermittent stream impacts for construction of the cul -de -sac, as well as construction of
single family homes on Lots 11 & 12. Since the previous NWP 29 and 401 WQC authorized
the 221 if of unimportant for the construction of a road and townhouses, it is anticipated
that the proposed 221 if of unimportant intermittent stream impacts for the construction of
the cul -de -sac and lots 11, 12 and 13 will be an issue. Furthermore, since the Corps waived
the 221 if of unimportant intermittent stream impacts in the permitted stream impacts in the
previously issued NWP 29, it is also assumed that these proposed 221 if of unimportant
intermittent stream impacts will also be waived and not counted towards the 300 if of
cumulative stream impacts allowed under a NWP.
Please note that Impact R consists of an aerial sewer crossing and stream impacts for
installation of the sewer crossing is not required.
WITHERS RAVENEL Page 4 of 7
ENGINEERS I PLANNERS I SURVEYORS
WITHERS II RAVEN EL
ENGINEERS I PLANNERS I SURVEYOR5
Buffer Impacts
The proposed project will result in 13, 490 sq ft of buffer impacts (z1: 7,568 sq ft; Z2: 5,922
sq ft).
Buffer impacts at Impacts R & T will occur from installation of a sewer crossing and
establishment of a sewer easement.
Buffer impacts at Impacts V, W and X will occur from construction of bypass channels.
Buffer impacts at Impact Y will occur from construction of the cul -de -sac. Due to the steep
grades and depth of the topographic crenulation at this impact, the buffers will be impacted
from fill necessary to return road fill to natural grade (see Sheet 2A). Please note that the
buffer impacts associated with Impact Y are less than was previously approved for the
previously designed road crossing.
Avoidance and Minimization
Prior to site plan design, the applicant requested that a detailed wetland delineation be
conducted so that impacts to wetlands and "waters" could be minimized.
The previously approved project consisted of a townhome development. As a result of the
current real estate market, townhome developments are not a desirable product in this area
of Raleigh and are not currently selling in the general area. Therefore, the site plan was
redesigned to be a single family residential development, which is a much more desirable
product. The redesign of the site plan resulted in the elimination of the road crossing at
Impact Y, and was replaced with a cul -de -sac. The location of the cul -de -sac was
determined by several factors. The proposed location of the cul -de -sac provides the
minimum road frontage for Lots 12 & 13 per the zoning requirements. If the cul -de -sac was
relocated farther to the east to attempt to reduce impacts, Lots 12 & 13 would not have the
20' of road frontage required, which is the minimum frontage allowed by the City of Raleigh
zoning requirements, and Lots 12 & 13 would not be developable. The River Run property
was purchased when real estate values were much higher. The project's profitability has
already been greatly reduced as a result of the change from a high density townhome
development to a much lower density single family development. Therefore, the loss of Lots
12 & 13 would greatly impact an already diminished profit margin, potentially rendering the
project financially unfeasible. Therefore, impacts at Impact Y have been minimized to the
greatest extent possible while maintaining a feasible project.
As was previously discussed, the cul -de -sac has been designed to extend just far enough to
provide the minimum lot road frontage required by the zoning requirements to make Lots 12
WITHERS RAVENEL Page 5 of 7
ENGINEERS I PLANNERS I SURVEYORS
WITHERS II RAVEN EL
ENGINEERS I PLANNERS I SURVEYOR5
& 13. If the cul -de -sac would have been designed to extend farther west to provide more
than the 20' minimum road frontage on Lots 12 & 13, the road would have exceeded the 150
If threshold for a 37.5' cul -de -sac radius for emergency vehicle turn - around, and would have
been required to have a 48' cul -de -sac radius. The expansion of the cul -de -sac from a 37.5'
radius to a 48' radius would have resulted in a significant increase in both buffer and
stream impacts. Therefore, impacts have been minimized to the greatest extent practical
while maintaining a feasible project. Impacts from the cul -de -sac at Impact Q were also
minimized through the use of a retaining wall to stabilize road fill.
Stream impacts were avoided at Impact R through the use of an aerial sewer crossing to
cross the stream.
Mitigation
Stream Mitigation
The previously issued NWP 29 and 401 WQC for the River Run Phases 4 &5 project required
98 if of stream mitigation to compensate for the 49 if of permanent perennial stream
impacts, which was purchased from Forrest Creek Mitigation Bank. A copy of the mitigation
receipt has been provided as an Appendix. Mitigation was not required for the 221 if of
unimportant intermittent stream impacts. Since the currently proposed design for the River
Run Phases 4 &5 project proposes the exact same stream impacts was previously permitted
and mitigated for, there is no additional stream mitigation proposed.
Buffer Mitigation
The proposed cul -de -sac at Impact Y is identified as "Allowable with Mitigation" in the NRB
Table of Uses, mitigation will be provided. Therefore, to mitigate for the proposed 6,979 sq
ft of buffer impacts proposed for Impact Y, the applicant proposes to purchase 16,048.5 sq
ft of riparian buffer mitigation from Wildlands Neuse Bank: Little River Farm. A copy of the
Letter of Reservation from Wildlands has been provided as an Appendix.
Stormwater Management Plan
The stormwater management plan consists of three level spreader /vegetated filter strip
systems. The stormwater management plan has been preliminarily approved by the City of
Raleigh, and will receive final approval upon issuance of the 404/4o1 authorization. Upon
issuance of the final stormwater management approval, a copy will be provided to NC -DWQ.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands
and "waters" could be minimized.
The previously approved project consisted of a townhome development. As a result of the current real estate market,
townhome developments are not a desirable product in this area of Raleigh and are not currently selling in the general area.
Therefore, the site plan was redesigned to be a single family residential development, which is a much more desirable
product. The redesign of the site plan resulted in the elimination of the road crossing at Impact Y, and was replaced with a
cul -de -sac. The location of the cul -de -sac was determined by several factors. The proposed location of the cul -de -sac
provides the minimum road frontage for Lots 12 & 13 per the zoning requirements. If the cul -de -sac was relocated farther to
the east to attempt to reduce impacts, Lots 12 & 13 would not have the 20' of road frontage required, which is the minimum
frontage allowed by the City of Raleigh zoning requirements, and Lots 12 & 13 would not be developable. The River Run
property was purchased when real estate values were much higher. The project's profitability has already been greatly
reduced as a result of the change from a high density townhome development to a much lower density single family
development. Therefore, the loss of Lots 12 & 13 would greatly impact an already diminished profit margin, potentially
rendering the project financially unfeasible. Therefore, impacts at Impact Y have been minimized to the greatest extent
possible while maintaining a feasible project.
As was previously discussed, the cul -de -sac has been designed to extend just far enough to provide the minimum lot road
frontage required by the zoning requirements to make Lots 12 & 13. If the cul -de -sac would have been designed to extend
farther west to provide more than the 20' minimum road frontage on Lots 12 & 13, the road would have exceeded the 150 If
threshold for a 37.5' cul -de -sac radius for emergency vehicle turn - around, and would have been required to have a 48' cul -de-
sac radius. The expansion of the cul -de -sac from a 37.5' radius to a 48' radius would have resulted in a significant increase in
both buffer and stream impacts. Therefore, impacts have been minimized to the greatest extent practical while maintaining a
feasible project. Impacts from the cul -de -sac at Impact Q were also minimized through the use of a retaining wall to stabilize
road fill.
Stream impacts were avoided at Impact R through the use of an aerial sewer crossing to cross the stream.

1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Construction techniques used to minimze impacts included headwalls and steeper fill slopes. Also, an aerial sewer crossing
will be used at Impact R to avoid stream impacts at this location.

For all NWPs that involve construction of culverts, measures will be included in the
construction that will promote the safe passage of fish and other aquatic organisms. For
all culvert construction activities, the dimension, pattern, and profile of the strearn,
(above and below a pipe or culvert), should not be modified by widening the stream
channel or by reducing the depth of the stream. Culvert inverts will be buried at least one
foot below the bed of the stream for culverts greater than 48 inches in diameter. For
culverts 48 inches in diameter or smaller, culverts must be buried below the bed of the
stream to a depth equal to or greater than 20 percent of the diameter of the culvert.

Dear Mr. Patsey:
You have our approval, in accordance with the attached conditions and those listed below, to place fill within or
otherwise impact 181 linear feet of perennial streams and 11,685 square feet (ft) of protected riparian buffers
for the purpose of a road crossing at the subject property, as described within your application dated April 2,
2004 and the additional information dated April 14, 2004. After reviewing your application, we have decided
that the impacts are covered by the N.C. Division of Water Quality (DWQ) General Water Quality Certification
Number 3402 (GC3402). The Certification allows you to use Nationwide Permit 39 when issued by the US
Army Corps of Engineers ( USACE).
In addition, you have our approval, in accordance with the attached conditions and those listed below, to
temporarily impact by excavation, or otherwise impact 98 linear feet of stream and 19,630 square feet (ft) of
protected riparian buffers [580(ft2) parallel Zone 1 impacts] for the purpose of constructing utility lines at the
subject property, as described within your application dated April 2, 2004 and the additional information dated
April 14, 2004. After reviewing your application, we have decided that the impacts are covered by the N.C.
Division of Water Quality (DWQ) General Water Quality Certification Number 3374 (GC3374). The
Certification allows you to use Nationwide Permit 12 when issued by the US Army Corps of Engineers
(USAGE).
This letter shall also act as your approved Authorization Certificate for impacts to the protected riparian buffers
per 15A NCAC 26 .0233. In addition, you should obtain or otherwise comply with any other required federal,
state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment
Control and Non - discharge regulations. Also, this approval 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 and you may be required to send us a new application. If the property is sold,
the new owner must be given a copy of this Certification and approval letter and is thereby responsible for
complying with all conditions. If total fills for this project (now or in the future) exceed one acre of wetland or
150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h).
In addition, you must follow the conditions listed in the attached certification and any additional conditions listed

devices shall be allowed in Zone 2 of the buffers provided that Zone 1 is not compromised and that
discharge is released as diffuse flow.
6. The outside buffer, wetland or water boundary as well as along the construction corridor within these
boundaries approved under this Certification shall be clearly marked by orange fabric fencing for the areas
that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities
to ensure compliance with 15A NCAC 2B .0250.
7. This Certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone
except for permitted areas associated with culvert conditions.
8. The project shall comply with 15A NCAC 2H .0219(i)(2)(G) and all other State, Federal and local sewer
system regulations.
9. Stormwater management structures shall be constructed and maintained according to the plans submitted
in the March 19, 2004 application.
10. All stormwater shall be directed as diffuse flow at non - erosive velocities through the protected stream
buffers and will not re- concentrate before discharging into the stream as identified within 15A NCAC 2B
.0233(5).
11. During the construction of the project, staging of equipment of any kind is not permitted in waters of the
State, or protected riparian buffers.
12. The dimension, pattern, and profile of the stream, above and below the crossing, should not be modified by
widening the stream channel or reducing the stream depth. Disturbed floodplains and streams should be
restored to natural geomorphic conditions.
13. Where practicable, culverts that are less than 48 -inch in diameter should be buried to a depth equal to or
greater than 20% of their size to allow for aquatic life passage. Culverts that are 48 -inch diameter or larger
should be buried at least 12 inches below the stream bottom to allow natural stream bottom material to
become established in the culvert following installation and to provide aquatic life passage during periods
of low flow. This may require increasing the size of the culvert to meet flow conveyance requirements. All
waters must flow through without freefalling or damming on either end of the culverts during low flow
conditions, to maintain aquatic life and/or fish passage.
14. Any riprap used must not interfere with aquatic life passage during low flow conditions.
15. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water.
This will lessen the chance of altering the stream's water chemistry and causing a fish kill.
16. Heavy equipment must be operated from the banks rather than in the stream channel in order to
minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream.
17. The presence of equipment in the channels must be minimized. Under no circumstances must rock,
sand or other materials be dredged from the wetted stream channel under this authorization, except in
the immediate vicinity of the culverts.
18. All mechanized equipment operated near surface waters must be regularly inspected and maintained to
prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
19. Riparian vegetation must be reestablished within the construction limits of the project by the end of the
growing season following completion of construction. All protected riparian buffers impacted by the
placement of temporary fill or clearing activities shall be restored to the preconstruction contours and
revegetated with native woody species upon completion of the project construction.

2. No Waste, Spoil, Solids, or Fill of Any Kind
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond
the footprint of the impacts depicted in the Pre - Construction Notification. All construction
activities, including the design, installation, operation, and maintenance of sediment and erosion
control Best Management Practices, shall be performed so that no violations of state water quality
standards, statutes, or rules occur.
3. Erosion and sediment control practices must be in full compliance with all specifications governing
the proper design, installation and operation and maintenance of such Best Management Practices in
order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Sediment and Erosion Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control
measures must be such that they equal, or exceed, the requirements specified in the most
recent version of the North Carolina Sediment and Erosion Control Manual. The devices
shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects,
including contractor -owned or leased borrow pits associated with the project.
c. Sufficient materials required for stabilization and /or repair of erosion control measures and
stormwater routing and treatment shall be on site at all times.
4. Sediment and Erosion Control Measures
Sediment and erosion control measures shall not be placed in wetlands or waters without prior
approval from the Division. If placement of sediment and erosion control devices in wetlands and
waters is unavoidable, design and placement of temporary erosion control measures shall not be
conducted in a manner that may result in dis- equilibrium of wetlands or stream beds or banks,
adjacent to or upstream and down stream of the above structures. All sediment and erosion control
devices shall be removed and the natural grade restored within two (2) months of the date that the
Division of Land Resources or locally delegated program has released the project;
5. Diffuse Flow

All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at
non - erosive velocities through the protected stream buffers such that it will not re- concentrate
before discharging into a stream as identified within 15A NCAC 2B .0233 (5). If this is not
possible, it may be necessary to provide stormwater facilities that are considered to remove
nitrogen. This may require additional approval from this Office.
6. Protective Fencing
The outside buffer, wetland or water boundary and along the construction corridor within these
boundaries approved under this authorization shall be clearly marked with orange warning fencing
(or similar high visibility material) for the areas that have been approved to infringe within the
buffer, wetland or water prior to any land disturbing activities;
7. Stormwater Management Plan Implementation Procedures (No Further Approval Needed)
• The approved SMP must be constructed and operational before any permanent building or
other structure is occupied at the site. If a development is phased, then the approved SMP for
each future phase must be constructed and operational before any permanent building or other
structure associated with that phase is occupied.
• The approved SMP, including the signed and notarized Operations & Maintenance
Agreement, as well as drainage patterns must be maintained in perpetuity.
• The SMP may not be modified without prior written authorization from the SMP approval
authority. If the SMP falls under another state stormwater program, then a copy of the
approval letter and the modified SMP must be submitted to the 401 Oversight/Express Unit
prior to the commencement of the modifications.
