6.5 PREPARATION
Compact subgrade to density requirements for subsequent backfill
materials. Cut out soft areas of subgrade not capable of compaction in
place. Backfill with ordinary fill material and compact to density equal
to or greater than requirements for subsequent fill material.
6.6 BACKFILLING, FILLING, AND SURFACE PREPARATION
Backfill areas to contours and elevations with unfrozen materials. Do
not backfill over porous, frozen, or spongy subgrade surfaces. Employ
a placement method that does not disturb or damage other work. Slope
grade minimum 2 inches in 10 feet, unless noted otherwise. Make
gradual grade changes. Blend slope into level areas. Place backfill and
fill in loose level lifts not to exceed six inches in thickness before
compaction. Make gradual grade changes. Blend slope into level
areas. Slope grade minimum 2 inches in 10 feet, unless noted
otherwise.
Earth fill in embankments, dams, levees, channel plugs, and other
structures designed to restrain the movement of water shall be placed
so as to meet the following additional requirements:
a. The distribution of materials throughout each zone shall be
essentially uniform and the fill shall be free from lenses, pockets,
streaks, or layers of material differing substantially in texture or
gradation from the surrounding materials.
b. Backfill areas to contours and elevations with unfrozen materials.
Do not backfill over porous, frozen, or spongy subgrade surfaces.
Employ a placement method that does not disturb or damage other
work. Place backfill and fill in loose level lifts not to exceed six
inches in thickness before compaction. Make gradual grade
changes. Blend slope into level areas. Slope grade minimum 2
inches in 10 feet, unless noted otherwise.
C. If the surface of any layer becomes too hard and smooth for proper
bond with the succeeding layer, it shall be scarified parallel to the
axis of the fill to a depth of not less than 2 inches before the next
layer is placed.
d. The top surfaces of embankments shall be maintained
approximately level during construction, except that a crown or
cross-slope of not less than 2% shall be maintained to insure
effective drainage, and except as otherwise specified for drain till
zones. If the Drawings or Specifications require, or the Engineer
directs, that fill be placed at a higher level in one part of an
embankment than another, the top surface of each part shall be
maintained as specified above.
c. Dams and other embankments shall be constructed in continuous
layers from abutment to abutment except where openings to
facilitate construction or to allow the passage of stream flow
during construction are specifically authorized in the Contract.
Embankments built at different levels as described under
SECTION 6.6-d or -e above shall be constructed so that the slope
of the bonding surfaces between embankment in place and
embankment to be placed is not steeper than 2 feet horizontal to 1
foot vertical. In areas where existing embankment is to be
flattened, topsoil shall be removed as described in SECTION 5.5
(Excavating). New embankment material shall be benched into
existing slope as shown on the plans. Short bench levels shall be
formed to a slope of 2H: I V or flatter, based on existing slope
conditions as determined by the Engineer at the time of
construction. Benching shall be constructed in such a fashion as
to inhibit the formation of preferential planes of slope failure. The
bonding surface of the embankment in place shall be stripped of
all loose material, and shall be scarified, moistened and
recompacted when the new till is placed against it as needed to
insure a good bond with the new fill and to obtain the specified
moisture content and density in the junction of the in-place and
S&EC Project No. 8243.D2 Page 8 Technical Specifications

new fill. Any variation to this method of tying new fill into the
existing embankment shall be determined in the field at time of
construction by the Engineer.
Independent testing laboratory (SECTION 3 - Quality Control) shall
monitor backfill and till placement. In-place density tests shall be
performed at least every two feet in elevation within the fill or backfill
and within the top one foot of fill or backfill where the higher density
requirement applies. If tests indicate backfill or fill material does not
meet specified rcquircmcnts, remove, replace, and retest backfill or fill.
6.7 COMPACTION AND QUALITY CONTROL
For backfilling of old stream channel, maintain moisture content of
backfill and till to within two percent of the optimum moisture content
by ASTM D698 for the particular soil being placed. Compact to greater
than or equal to 95 percent of the maximum dry density by ASTM
D698 for the particular soil being placed unless otherwise accepted by
the Engineer. Lift thickness shall not exceed 6".

7.6 IN-STREAM STRUCTURES
The work covered by this section consists of the construction of in-
stream structures including rock cross vanes (with or without rock
steps) and rock or log j-hooks (with or without rock steps).
The quantity of in-stream structures to be constructed will be affected
by actual conditions that occur during the construction of the project.
The type and quantity of structures may be increased or decreased at
the direction of the Engineer. Such variations in quantity will not be
considered as alterations in the details of construction or a change of
character of the work.
A tracked hydraulic excavator with a thumb of sufficient size to move
specified boulders is required for this item. Precise placement of
structures will be determined during construction by the Engineer and
may not reflect the construction drawings. In-stream structures
installed must be inspected and approved by the Engineer. Excavation
for the purpose of installing structures is incidental and is covered by
this line item.
The excavation of the subgrade and installation of the structure will be
consecutive and continuous. Once the installation procedure has
initiated it will be completed before the end of the workday. Any
incidental/accidental discharge of sediment accumulation as a result of
the installation procedure will be removed or integrated into the
designed bedform. Excavation shall terminate at bedrock if contacted
prior to the design grade. Bedrock will be excavated only if it is
determined to be rippable and necessary by the Engineer.
Grade area where structures are to be constructed. Surface shall be free
of obstructions, debris, and pockcts of soft or low density material.
Unless otherwise directed by the Engineer, the stone shall be placed on
the slope and/or angle as indicated on the plans. The stone shall be
graded so that the smaller stones are uniformly distributed throughout
the mass. The Contractor may place the stone by mechanical methods,
augmented by hand placing where necessary, provided that when the
rip rap is completed, it forms a properly graded, dense, neat layer of
stone. Drop height shall be not more than one foot.
Place rock cross vanes and j-hooks (and rock sections of log j-hook) as
shown in Drawings. Footer rocks shall be installed to define shape of
in-stream rock structures, and the arms of in-stream log j-hooks.

areas to be seeded. Where topsoil is unavailable, seedbeds may be
prepared directly on the exposed finished grade or topsoil may be
imported.
If topsoil is used, it should be spread to a uniform depth of four to six
inches and bonded to the subsoil by loosening with a disc, harrow, or
chisel plow. Areas where seeding will occur on exposed finished grade
shall be disked or harrowed to ensure soil aeration and to increase the
surface roughness prior to planting.
Apply lime and fertilizer evenly across seedbed and work into the top
4-6 inches of soil by discing or other suitable means. Operate
machinery on the contour.
Rework the surface if soil becomes compacted or crusted prior to
seeding. Complete seedbed preparation by breaking up large clods and
raking into a smooth, uniform surface. Fill in or level depressions that
can collect water.
9.6 SEEDING
Apply permanent seeding to seedbed after preparation is complete. Use
certified seed for permanent seeding whenever possible. Certified seed
is inspected by the North Carolina Crop Improvement Association. It
meets published North Carolina Standards and should bear an official

during construction. The Contractor shall utilize the specified and
S&EC Project No. 8243.D2 Page 17 Technical Specifications
Copper Ridge Repair & Stabilization July 2006
appropriately sized pumps to convey the diversion of water flow away
from the work area without creating a flood hazard or scour. The
Contractor is responsible for determining (based on the direction of the
Engineer) the location of coffer dams, pumps, discharge hose route,
stilling basins, splash pads, and period of operation prior to the
initiation of any pumping. An attempt will be made to complete all
grading, channel shaping, in-stream structure construction, and
stabilization for each section within one day. If work for any particular
section cannot be completed in one day, a 24-hour pumping operation
will be set up and maintained to facilitate the construction schedule.
Bypass Pump
The pump used to convey the stream flow around the work area during
construction should be capable of pumping and discharging an
estimated 90 gallons per minute. The Contractor is responsible for
selecting a properly sized pump. This unit should be a silent and self-
priming model with a self-contained fuel tank large enough to facilitate
a 24-hour pumping operation. The pump should also be matched with
the necessary footage of flexible or ductile hose and appropriately sized
fittings.
Dewatering Pump
A second pump shall be used to dewater the work area between the
dams (with Temporary Sediment Basin). The pump must be of
sufficient size to dcwatcr the work area and pump that water from the
bottom of the work area to the special stilling basin. The pump should
be matched with the necessary footage of hose and the required fittings.
Special Stilling Basin
The special stilling basins are covered in detail under the "Special
Stilling Basins" section below.
Temporary Splash Pad
A temporary splash pad shall be used to dissipate energy from the
discharge from the bypass pump. Alternatively, check dams may be
modified and used for this purpose as determined by the Engineer.
The temporary splash pads are covered in detail under the "Temporary
Splash Pads" section below.
10.13 SPECIAL STILLING BASINS
The work covered by this section consists of fumishing, placing, and
removing special stilling basins as directed by the plans and the
Engineer. The special stilling basins shall be used to filter pumped
water during construction. The quantity of special stilling basins may
be increased, decreased, or eliminated entirely at the direction of the
Engineer. Such variations in quantity will not be considered as
alterations in the details of construction or a change in the character of
work.
The special stilling basins shall be a water permeable fabric bag that
traps sand, silt, and lines from the sediment laden water entering. The
filter fabric shall meet the requirements of Section 1056 for Type 2
Fabric.
The special stilling basin shall be a bag constructed to a minimum size
of 10' X 15' made from nonwoven fabric. There shall be a sewn-in 8
inch spout for receiving pump discharge. The bag scam shall be sewn
with a double needle machine using a high strength thread. The seams
shall have a minimum width strength of 60 lb/in (ASTM D-4884).
The fabric used to construct the bag shall be stabilized to provide
resistance to ultra-violet degradation and meet the following
specifications for flow rates, strength, and permeability:
Weight 8 oz/yd (ASTM D-3776)
Grab Tensile 200 lb (ASTM D-4632)
Puncture 130 lb (ASTM D-4833)
Flow Rate 80 gpm/sf (ASTM D-4491)
Permittivity 1.51/sec(ASTM D-4991)
UV Resistance 70 % (ASTM D-4355)
The special stilling basins shall be placed so the incoming water flows
through the bag without causing erosion. The bag will rest on
Nonwoven Type 2 filter fabric. The contractor will grade the bed to
ensure that the filtered water exits at the desired location. The exit
location shall be chosen to prevent erosion. The neck or spout of the
bag shall be tied tightly to prevent water from exiting the bag without
passing through the walls. The special stilling basin shall be disposed
of and replaced when it is'/. full of sediment, becomes torn or
punctured, or is unable to filter sediment at a reasonable flow rate.
Approval from Engineer must be received prior to removal and
replacement of special stilling basins. Contractor is responsible for
providing the necessary quantity of special stilling basins for the
duration of the project.
10.14 TEMPORARY SPLASH PADS
Non-woven gcotcxtile shall be placed under entire pump around outlet
splash pad. The placement surface shall be free of obstructions, debris,
and pockets of soft or low density material. The fabric shall be laid
smooth and free from tension, stress, folds, wrinkles or creases.
Horizontal overlaps shall be a minimum of 12 inches with the upper
fabric overlapping the lower fabric. Vertical overlaps in fabric shall be
a minimum of 18 inches with the upstream fabric overlapping the
downstream fabric. Outer edges of fabric shall be anchored in trench at
least one foot deep. No more than 72 hours shall elapse from the time
the fabric is unwrapped to the time it is covered with #57 stone. In the
event that the fabric is displaced or damaged during the placement of
rip rap, the rip rap shall be removed and the fabric repositioned or
replaced prior to the placement of the rip rap. This will occur at no
additional cost to the Owner.
Erosion Control Stone shall be placed over cushion layer to depth
indicated on the plans. The completed rip rap shall be at least the
thickness indicated on the plans. Drop height shall be not more than
two feet.
Unless otherwise directed by the Engineer, the stone shall be placed as
indicated on the plans. The stone shall be graded so that the smaller
stones are uniformly distributed throughout the mass. The Contractor
may place the stone by mechanical methods, augmented by hand
placing where necessary, provided that when the rip rap is completed it
forms a properly graded, dense, neat layer of stone.
Each outlet splash pad shall be installed such that the downstream end
of the apron provides a smooth transition to the existing grade or
channel bed.
10.15 TEMPORARY SEEDING
The Contractor shall provide all labor, materials, tools, and other items
necessary to provide temporary seeding in accordance with State and
local Standards.
Areas where no substantial or significant progress is made for more
than 15 days shall be temporarily seeded as shown on the Drawings and
specified herein. All areas must be seeded, mulched, and anchored
S&EC Project No. 8243.D2 Page 18 Technical Specifications

Hey Laurie,
Attached is the 401 modification for Copper Ridge, a violation site in Wake County
that we discussed yesterday.. The original project number was 04-0849. I'm not
sure if it needs a new number or not. Please advise. I will bring the new
information (mod request and restoration plans etc.) for your files during lunch
tomorrow.
thank you!

River Buffer Protection Rules (15A NCAC 2B .0233) -,vith Additional Conditions
Dear Mr. Granholm:
You have our approval, in accordance with the attached conditions and those listed below, to
place fill within or otherwise impact 111 feet of streams and 25,825 square feet (ft) of protected
riparian buffers for the purpose of widening Creedmoor Road at the subject property, as
described within your application dated May 24, 2004 and received by the N.C. Division of
Water Quality (DWQ) on May 24, 2004. After reviewing your application, we have decided that
the impacts are covered by General Water Quality Certification Number(s) 3404 (GC3404). The
Certification(s) allows you to use Nationwide Permit(s) 14 when issued by the US Army Corps
of Engineers (USACE). This letter shall also act as your approved Authorization Certificate for
impacts to the protected riparian buffers per 15A NCAC 2B .0233. In addition, you should
obtain or otherwise comply with any other required federal, state or local permits before you go
ahead with your project including (but not limited to) Erosion and Sediment Control and Non
discharge regulations. Also, this approval to proceed with your proposed impacts or to
conduct impacts to waters as depicted in your application shall expire upon expiration of
the 404 Permit.
This approval is for the purpose and design that you described in your application. If you change
your project, you must notify us and you may be required to send us a new application. If the
property is sold, the new owner must be given a copy of this Certification and approval letter and
is thereby responsible for complying with all conditions. If total fills for this project (now or in
the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may
be required as described in 15A NCAC 2H .0506 (h). This approval requires you to follow the

RE: Nationwide Permit 14, 401-Certification, & Neuse River Buffer Compliance Request
Wake Estates Property/Creedmoor Road Widening
Raleigh, Wake County, North Carolina
040849
Dear Mrs. Burdette and Mssrs. Dorney and Zaraecki:
On behalf of Wake Estates LLC, we request authorization from the US Army Corps of Engineers
(USACE) to use Nationwide Permit (NWT) 14 for the proposed project to cover permanent impacts to
one stream channel. We also request written concurrence from the NC Division of Water Quality
(NCDWQ) that the project complies with the associated 401 Water Quality Certification requirements,
and complies with the Neuse River Basin (NRB) Buffer Rules. A Pre-construction Notification
Application (PCN) is attached, which includes an agent authorization form.
The proposed project consists of the widening of Creedmoor Road (Highway 50) needed for the
expansion of an additional lane along Creedmoor Road. The City of Raleigh is requiring the property
owner to install this additional lane prior to site approval. For this reason, the site does not currently have
a final site plan because the owner did not wish to invest the time and money associated with developing
such a plan if the Creedmoor Road impacts were not permittable. The project site is approximately 14
acres and is located on the west side of Creedmoor Road (Highway 50), approximately 2000' north of the
intersection of Creedmoor Road and Glenwood Avenue (Highway 70).. Please refer to the USGS
Location Map for the location of the property (Figure 1).
The original plan for the proposed road widening impacted 400 linear feet of stream but has since been
revised to impact only 111 linear feet of channel. At the request of the applicant, S&EC conducted a
detailed wetland delineation and stream buffer evaluation on the property on October 3, 2003. Ms.
Debbie Edwards of the NC-DWQ confirmed our buffer determinations on October 30, 2003 (NBRRO 03-
286). Please refer to the attached confirmation letter by Ms. Edwards. The subject site is shown on the
applicable Wake County Soil Survey map (Figure 2). A wetland sketch map and DWQ buffer letter are
attached in support of the wetland delineation.

Mr. Steve Mitchell visited the site on 2 December 2003 to make perennial calls on the property. Because
the feature appears to be spring fed, the stream becomes perennial +/- 15 feet from the beginning of the
buffered channel. A site meeting was held with Mr. Zarzecki of the NC DWQ to discuss the project and
its potential buffer impacts. During this site meeting we waked the portion of the stream where the
proposed buffer and stream impacts are planned and observed the existing culverts. This section of
stream is immediately adjacent and parallel with the existing Creedmoor Road and is piped under existing
road fill in two locations. This stream also has two existing culverted crossings that provide driveway
access to the site. One of these crossings will be utilized to provide road access to the site.
In an effort to minimize stream and buffer impacts as much as possible, the applicant modified the plan to
incorporate retaining walls, and reduced the impact by more than 80%, to 111 linear feet of channel.
Proposed mitigation for the perennial stream impacts has been requested from the EEP. Because the
impacted stream is being relocated and not piped, S&EC believes that mitigation exceeding a 1:1 ratio
would be excessive. The proposed road expansion will cross a portion of one stream channel and a
portion of the riparian buffer of the same stream. This stream is adjacent to Creedmoor Road and nearly
parallel to the road in a heavily developed area. The impact tables in the PCN itemize and provide a
description of each proposed impact to stream channels and riparian buffers. The total proposed impact
to the perennial stream channel is 111 linear feet. The total proposed impact to riparian buffers are
19,086 ft2 in zone 2 and 6,739 ftz in zone 1. Within the total proposed buffer impacts, Zone 1 impacts of
731 ft2 and Zone 2 impacts of 195 ft2 result from a perpendicular crossing and therefore should not
require mitigation. Please refer to the attached Impact Maps (5 sheets) for the location of each impact.
Because these areas are parallel road impacts, buffer mitigation is assumed. The client proposes payment
to EEP to meet the buffer mitigation requirements.

Sean Clark

stabilization activities (cement wall, rip-rap, crib wall, 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.
** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest
downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at
www.usgs.gov. Several intemet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com,
www.mapquest.com, etc.).

5. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
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.
At the request of the client a detailed wetland delineation and stream buffer determination
was conducted by S&EC The original plan for the proposed road widening was to impact +/-
400 linear feet of stream The applicant reduced this amount by utilizing retaining walls to
decrease the footprint of the impact Likewise the retaining walls will reduce the required buffer
impacts The widening of Creedmoor road is required by the City of Raleigh.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
Page 5 of 8
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 D`'VQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://l12o.enr.statc.nc.us/ncwetlands/strm9ide.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.
In order to cover the cost of mitigation, payment to the Environmental Enhancement
Program is proposed. Because the stream impact is due to a relocation and not a filling or
culverting, we propose a mitigation ratio of 1:1.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/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): 111
Amount of buffer mitigation requested (square feet): 47,165
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

Raleigh, Wake County, NC
Dear Mr. Clark:
This letter will serve as confirmation of the buffer determination made by S&EC at the subject
property referenced by the Raleigh Regional Office as NBRRO 03-286.
On October 30, 2003,1 conducted a site visit of features A, B and C involved in the above
referenced project as identified on the attached figures 1 and 2. It was determined that the features
shown on the Wake County Soil Survey, but absent on the USGS Raleigh West, NC Quad map
could potentially be subject to protection under the Neuse River Basin: Nutrient Sensitive Waters
Management Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code
T15A: 02B.0233 (NCAC .0233). Feature A has been delineated and flagged and its origin is
identified as flag #S03, the pond above this feature (feature C) is not subject. Feature B is not
subject.
This letter only addresses the applicability of the Neuse Buffer Rules. For information
relevant to 401 Water Quality Certifications, wetlands and other impacts to "waters of the state",
please contact the Central Office at 733-1786. (Note: if a 401 Water Quality Certification is needed,
please be reminded not to begin your project until the certification has been received.) 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.

Stream Repair and Stabilization Plan
Wake County, NC
Dear Ms. Higgins:
Soil & Environmental Consultants, PA (S&EC), has been engaged by Pulte Homes to
prepare a Repair and Stabilization Plan for stream impacts caused by the failure of a
retaining wall onsite and the subsequent installation of inline erosion and sedimentation
(E&S) control devices within an unnamed tributary of Crabtree Creek.
The purpose of this letter is to describe in detail our plan for removal of inline E&S
control measures onsite, as well as the repair of stream channel reaches impacted by the
E&S devices.
Site Description
The 14 acre project site is located to the west of Creedmoor Road, approximately 2,000
feet north of its intersection with Glenwood Avenue (Highway 70), in Raleigh, North
Carolina. The stream in question is an unnamed tributary of Crabtree Creek (a tributary
to the Neuse River) which flows along the east side of the property parallel to Creedmoor
Road. A vicinity map is provided in Figure 1.
Project History
A storm event on August 14, 2005, caused the failure and collapse of a large retaining
wall and sediment basins within the Copper Ridge development, resulting in the
deposition of sediment within the stream channel and riparian buffer. The depth of
sedimentation was observed to be between 9 and 12 inches at various locations along the
subject reach. On August 22 and 25, 2005, the City of Raleigh and the Division of Water
Copper Ridge
Soil & Environmental Consultants, PA
July 20, 2006
Project No. 8243.D2
Quality (DWQ) respectively, issued Notices of Violation (NOV) to Pulte Homes
following a site inspection on August 17, 2005, by Mr. Kelly Daniels of the City of
Raleigh and Mr. Mike Horan of DWQ.
On September 1, 2005, S&EC, was contracted by Pulte Homes to prepare a clean-up plan
to address issues described in the violations issued in August 2005. During an initial site
visit, the impacted area was traversed and the extent of the impacts was observed.
During this process we identified, delineated (with sequentially numbered flags), and
GPS located the approximate boundaries of the sediment impacts. On September 30,
2005, the clean-up plan was submitted to DWQ. Clean-up operations consisted of
manually removing sediment from the stream channel and buffer in areas where sediment
exceeded 2 inches in depth as well as adjusting, repairing, and maintaining E&S control
measures.
On October 17, 2005, the clean-up plan was approved. Edge Development was
contracted to conduct site clean-up operations, which began in late October. On
November 10, 2005, a site meeting took place with Mike Horan of DWQ and S&EC to
evaluate the progress of clean-up operations. During this site visit, Mr. Horan identified
several problem areas with the E&S control measures onsite. These problems were
addressed by S&EC in a letter to DWQ on November 15, 2005. On December 20, 2005,
S&EC conducted a site visit with Edge Development to assess progress on clean-up
operations, to identify areas requiring additional sediment removal, and to discuss
implementation of recommendations made by DWQ during the November site meeting.
S&EC received notification from Edge Development that clean-up operations were
complete on December 30, 2005. S&EC verified completion of clean-up operations
during a site visit on January 4, 2006.
In January 2006, S&EC was notified that the Creedmoor Road widening project was
suspended pending approval from the City of Raleigh and North Carolina Department of
Transportation (NCDOT). It was recommended by DWQ that E&S control measures
should be maintained and the stream channel stabilized until the new road plan was
approved. On February 19, 2006, S&EC received a draft letter from DWQ in response to
the November 2005 submittal. A formal letter was not received. On March 8, 2006,
DWQ conducted a site inspection to determine compliance with applicable permits.
On April 4, 2006, DWQ issued a Notice of Continuing Violation. A site meeting took
place on April 21, 2006, between DWQ, Pulte Homes, S&EC, Edge Development, and
the CE Group. At this time, S&EC was contracted to prepare a Stream Repair and
Stabilization Plan to remove remaining in-stream sediment basins and to repair the areas
of stream impacted by these structures. A letter was sent to DWQ by Pulte Homes on
May 3, 2006, detailing responses and remedies to the specific violations addressed in the
Notice of Continuing Violation.
Proposed Repair Plan
On July 13, 2006, S&EC performed a limited engineering survey of the existing impacted
stream as well as a reference reach survey of the relatively un-impacted channel segment
upstream of the upper inline sediment basin. From the analysis of this data as well as
Page 2 of 5
Copper Ridge
Soil & Environmental Consultants, PA
July 20, 2006
Project No. 8243.132
data from the North Carolina State University, Stream Restoration Institute (SRI)
Piedmont Regional Curve, we determined the typical repaired stream bankfull
dimensions including a Bankfull Width (Wbkf) of 80 feet, Mean Depth (Dbkf) of 0.7 feet
and Bankfull Cross-sectional Area of 5.4 square feet.
The repaired stream will be a Rosgen B-Type Channel (see Sheets 7 and 8 of the
enclosed Construction Drawings for existing as well as proposed cross-sections through
the repaired section. Stationing has been assigned for the restored alignment as shown on
Sheets 3 through 5 of the Construction Drawings. Three repairs and stabilization
segments were proposed; from Station 0+00 to Station 0+55 (Reach 1), from Station
1+50 to Station 2+75 (Reach 2), and from Station 5+25 to Station 7+25 (Reach 3).
Recommended repairs for the stream are as follows:
Reach 1
Much of existing upper inline sediment basin will be filled, and a
restored section of stream will be built through the former basin
footprint from Station 0+00 to Station 0+55 (see Sheet 3 of 12). Rock J-
hooks and Cross Vanes will be used in restored sections to relieve near
bank shear stress, provide grade control, and dissipate energy. Proposed
structure locations for this restored reach are shown on Sheet 3 of 12,
and details of these in-stream structures are shown of Sheet 9 of 12. A
bankfull bench of 5 feet is recommended on the left bank (looking
downstream) and up to 5 feet on the right bank as space allows. Grading
of this bench will be at 3H:1 V or flatter side slopes to ensure stability.
S&EC suggests that if retaining walls are used to decrease the side
slopes to current grade outside the stream valley, they should be located
at the edge of this bankfull bench. Proposed cross-sections showing the
possible location and height of retaining walls are shown in Sheets 7 and
8, however these are only suggestions, their use will require separate
Agency Approval. The design of any such retaining wall structures will
be performed by others. The existing check dam located at Station 0+53
will be removed after stream repair has been completed and all loose
sediment upstream has been removed and properly disposed of.
Reach 2
The existing section of stream from Station 1+50 to Station 2+75 is
currently stable, however, in-stream structures are proposed at the outlet
of an existing stormwater pipe at Station 1+50, and the steep section of
stream at Station 2+60 to ensure the long term stability of this reach.
Proposed structure type and location for this reach can be seen on Sheet
4 of 12.

Soil & Environmental Consultants, PA
Reach 3
July 20, 2006
Project No. 8243.132
The section of stream from Station 5+25 to Station 7+25 is relatively
stable, however it lacks proper dimension and pattern and is devoid of
stream facets after grading that was performed in this reach in 2005.
Proposed pattern and structures recommended for this section are shown
on Sheet 5 of 12. The existing inline sediment basin and check dam
located at Station 7+00 will be removed after restoration has been
completed and all loose sediment upstream has been removed and
properly disposed of.
Erosion and Sedimentation Control Measures are shown on Sheets 10 through 12 and the
Construction Sequence is outlined on Sheet 11 of 12. A proposed planting plan and
planting details are shown on Sheet 12. The proposed planting extends from the
Creedmor Road right of way on the left (looking downstream) to tie in with the existing
undisturbed buffer on the right. Adjustments on the exact extent of planting may be
necessary during construction based on final site grading, and utility and infrastructure
placement.
Future Monitoring & Maintenance
Once in-stream sediment basins have been removed and stream repairs have been
completed, we recommend that the impacted areas be monitored until such time as major
site construction is completed and exposed site surfaces have been stabilized with
vegetative cover, leaf litter, or a combination thereof.
Monitoring should consist of a traversing the length of the impacted stream reach for the
purpose of observing the condition of the channel bed and banks and the adjacent buffers.
Observations will be recorded regarding identified sediment loading (if any), its apparent
source, and recommendations made for supplemental clean-up or stabilization measures.
We recommend these monitoring visits be conducted on a monthly basis for the first six
(6) months after completion of repair operations. Should additional areas need repair or
other areas of sediment impact be identified in this process, visits may continue on a
monthly basis for an extended period of time.
Where necessary, the repair or supplementation of silt fence, seeding, and mulching
measures installed in and around the impacted buffer areas will be performed.
Additionally, the continued inspection, clean out, and repair of all site E&S measures as
described above will be performed.
Please contact me if you have any questions or comments regarding this repair plan. We
thank you for your assistance and project input to date and look forward to the successful
completion of the repair phase of this project.

401 Modification Request
Wake County, NC
Dear Mr. Smith:
00
,? OG p? a
Soil & Environmental Consultants, PA (S&EC), was engaged by Pulte Homes to prepare
a Repair and Stabilization Plan for stream impacts on the above referenced site which has
been submitted and reviewed by the Division of Water Quality (DWQ). It is our
understanding that a modification to the original 401 Nationwide Permit (NWP) issued
for the site will be required. This letter serves as a formal request for that modification
and further details the proposed construction schedule and monitoring activities.
Proposed Construction Schedule
Construction is expected to commence on or around October 1, 2006, pending the receipt
of the modified 401 permit. We would expect construction to be completed within 6 to 8
weeks of the start date. S&EC personnel will be onsite regularly to observe construction
and to make any necessary field adjustments.
Future Monitoring & Maintenance
Once in-stream sediment basins have been removed and stream repairs have been
completed, we recommend that the impacted areas be monitored for three years.
Monitoring should consist of a traversing the length of the impacted stream reach for the
purpose of observing the condition of the channel bed and banks and the adjacent buffers.
Observations will be recorded regarding identified sediment loading (if any), its apparent
source, and recommendations made for supplemental clean-up or stabilization measures.
Representative photos will be taken at several locations along the reach. We recommend

these monitoring visits be conducted on a monthly basis for the first six (6) months after
completion of repair operations and quarterly after that.
Where necessary, the repair or supplementation of silt fence, seeding, and mulching
measures installed in and around the impacted buffer areas will be performed.
Additionally, the continued inspection, clean out, and repair of all site E&S measures as
described above will be performed.
404 Nationwide Permit
As discussed in a meeting with Jean Manuele and Thomas Brown of the Raleigh
Regulatory Office of the Wilmington District of the U.S. Army Corps of Engineers
(USACE) on September 11, 2006, due to the unauthorized activities and non-compliance
with the original 404 permit issued in August 2004, remedial action will be required by
the USACE. This remedial action will include the implementation of the Stream Repair
and Stabilization Plan submitted to the Agencies on July 20, 2006. Record of this non-
compliance and the request to implement the repair plan is attached.
Please contact me if you have any questions or comments regarding this request. We
thank you for your assistance and project input to date and look forward to the successful
completion of the repair phase of this project.
Sincerely,
SOIL & ENVIRONMENTAL CONSULTANTS, PA
