Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse River
Buffer Protection Rules (15A NCAC 2B.0233) with Additional Conditions
Dear Mr. Bailey:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.014 acres of wetlands, 267 feet of streams, 20,799 square feet (ft) of Zone 1
and 17,878 square feet (ft) of Zone 2 of protected riparian buffers for the purpose of constructing a
parkway extension at the subject property, as described within your application dated June 22, 2005 and
received by the N.C. Division of Water Quality (DWQ) on June 27, 2005 with additional information
received on June 29, 2005. After reviewing your application, we have decided that the impacts are
covered by General Water Quality Certification Number(s) 3404 and 3495 (GC3404 and 3495). The
Certification(s) allows you to use Nationwide Permit(s) 14 and 13 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 213 .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 or CAMA 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 conditions listed in the attached
certification and any additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific and general
conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are
approved including incidental impacts:

2. Erosion & Sediment Control Practices
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.
3. Compensatory Mitigation Using the Ecosystem Enhancement Program
Mitigation must be provided for the proposed impacts as specified in the table below. We
understand that you wish to make a payment to the Wetlands Restoration Fund administered by
the NC Ecosystem Enhancement Program (EEP) to meet this mitigation requirement. This has
been determined by the DWQ to be a suitable method to meet the mitigation requirement. Until
the EEP receives and clears your check (made payable to: DENR - Ecosystem Enhancement
Program Office), no impacts specified in this Authorization Certificate shall occur. The EEP
should be contacted at [phone] if you have any questions concerning payment into a
restoration fund. You have one month from the date of this approval to make this payment. For
accounting purposes, this Authorization Certificate authorizes payment into the Wetlands
Restoration Fund to meet the following compensatory mitigation requirement:
Compensatory Mitigation Required River and Sub-basin Number
Stream 267 feet 03-04-02/27-43-2.5
4. Buffer Mitigation
You are required to mitigate for impacts to the protected riparian buffers. The required area of
mitigation to compensate for impacts to the protected riparian buffers is 89,214 square feet as
required under this Authorization Certificate and 15A NCAC 2B .0242(buffer mitigation rule).
We understand that you wish to make a payment into the Riparian Buffer Restoration Fund
administered by the NC Ecosystem Enhancement Program (EEP) to meet this mitigation
requirement. This has been determined by the DWQ to be a suitable method to meet the
mitigation requirement. In accordance with 15A NCAC 2B .0242(7)(buffer mitigation rule), this
contribution will satisfy our compensatory mitigation requirements under 15A NCAC 2B
.0233(10)(buffer protection rule). Until the EEP receives and clears your check (made payable
to: DENR - Ecosystem Enhancement Program Office), no impacts specified in this Authorization
Certificate shall occur. The EEP should be contacted at [phone] if you have any
Town of Cary

questions concerning payment into the Riparian Buffer Restoration Fund. You have one month
from the date of this approval to make this payment. For accounting purposes, this
Authorization Certificate authorizes payment into the Riparian Buffer Restoration Fund to
compensate for 89,214 ,ftz of required riparian buffer mitigation for impacts to 38,677 fe of
protected riparian buffers (Zone 1= 20,799 W, Zone 2 =17,878 ftz); 03-04-02 river and 27-
43-2.5 stream index."
5. Diffuse Flow
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).
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 to ensure compliance
with 15A NCAC 2B .0233 and GC 3404.
7. Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream profiles
are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and
longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall
be designed and installed to allow for aquatic life movement as well as to prevent head cutting of
the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall
be re-established or, if the pipes installed in a perched manner, the pipes shall be removed and re-
installed correctly.
8. 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.
9. No Sediment & Erosion Control Measures w/n Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters
is unavoidable, they shall be removed and the natural grade restored within six months of the date
that the Division of Land Resources has released the project.

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. S&EC delineated streams and wetlands on site in October 2004 and
March 2005. NC DWQ confirmed buffer start points in a letter dated 30 November 2004 (DWQ
EXP 04-1821). Kevin Yates of the USACE evaluated wetlands and jurisdictional waters on site
on 07 April 2005 and made importance and perennial stream calls. Eric Kulz of NC DWQ
evaluated two additional features on 9 May 2005, and confirmed buffer start points on those
features (see attached letter dated 2 June 2005).
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 additional permit reauests are anticipated for the extension of Regency Parkway.
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
nprap 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
Page 3 of 10
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.
L Provide a written description of the proposed impacts: The applicant proposes one
new road crossing Because the right-of-way was dedicated so many years ago, 181 linear
feet of channel impact at impact 3B could not be minimized further. The applicant also
proposes upgrading an existing crossing of two streams. The current stream crossing was
constructed more than 20 ergo and is much degraded. The proposed plan will upgrade
the crossing to comply with current regulatory and stream stability requirements, impacting
134 linear feet of channel. Only 86 linear feet of channel should be considered impacted and
"lost" as bank stabilization accounts for 48 linear feet of the stream impacts resulting from
the proposed upgrade Please see XV Other Circumstances for additional information.
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,

VII. Iimpact 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 Regency Parkway right-
of-way was gpproved and dedicated many years ago. It is currently owned by the Town of Carte
For most of the route, the applicant is following the alignment of a previously graded road while
the road could be realigned, it could only be moved further downstream, which would not reduce
impacts.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
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 fimctions 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
htip://h2o.enr.state.nc.us/ncwetlands/strmy-ide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The applicant proposes to mitigate via the NC EEP. The applicant proposes stream
mitigation at a 1:1 ratio, and buffer mitigation at ratios and in amounts detailed below. The
applicant proposes no wetland mitigation.

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.nc.us/ncwetlands. If no, please provide a short narrative description: A large
portion of adjacent property is already developed. The remaining undeveloped property is
accessible via other existing roads In addition any new development would have to meet Town
of Carte regulations 'which are intended to protect water quality. Therefore, we believe that
gp?ropriate standards are in place to protect water quality.
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).
The current culvert at Figure 1 predates available institutional memorL which extends back to
1985 According togeotechnical analysis conducted by the site engineer, the culvert material is
at the end of the service life. It does not meet current construction or environmental standards.
The applicant proposes upgrading the existing, culvert to conform to modern engineering norms
and environmental requirements Stabilization and fill impacts are described in the relevant
sections of this PCN and detailed in Figure 1 of the Wetland and Buffer Impacts maps.

On-Site Determination for Applicability to the Neuse River Riparian Area Protection Rules
(15A NCAC 2B.0233)-EXPRESS REVIEW PROGRAM
D= Mr. Stephens:
On November 29, 2004, at your request I conducted an on-site determination to review six
features located on the subject property for applicability to the Neuse Buffer Rules (1 SA NCAC
2B .0233). The features are labeled as "A, B, G, I, J and L" on the attached maps initialed by me
on November 29, 2004,
;The Division of Water Quality (DWQ) has determined that the features labeled as "A, B, It
J and L" on the attached maps are subject to the Neuse Buffer Rule. The origins of these
features have been delineated and identified in the field. )Features A and B are both subject
from the property boundaries through to the conflneuees of Y3 and C, consecutively.
Feature I starts at flag # S-06. Feature J starts at flag # S-04. Feature L starts at flag # S-
03. Feature G is not subject. These features and their associated buffers should be identified
on any future plans for this property. The owner (or future owners) should notify the DWQ (and
other relevant agencies) of this decision in any future correspondences concerning this property.
This on-site determination shall expire five (5) years from the date of this letter.
Landowners or affected parties that dispute a determination made by the DWQ or Delegated
Local Authority that a surface water exists and that it is subject to the buffer rule may request a
determination by the Director. A request for a determination by the Director shall be referred to
the Director in writing clo John Dorney, DWQ Wetlands/401 Unit, 2321 Crabtree Blvd.,
Raleigh, NC 27604-2260. Individuals that dispute a determination by the DWQ or Delegated
Local Authority that "exempts" a surface water from the buffer rule may ask for an adjudicatory
hearing. You must act within 60 days of the date that you receive this letter. Applicants are
hereby notified that the 60-day statutory appeal time does not start until the affected party
(including downstream and adjacent landowners) is notified of this decision. DWQ recommtmds
that the applicant conduct this notification in order to be certain that third party appeals are made
in a timely manner. To ask for a hearing, send a written petition, which conforms to Chapter

1. After construction and until vegetation has been established, level spreader(:; shall be inspected after
every rainfall- Thereafter, level spreader(s) shall be inspected at least every r ionth and more
frequently during the fall season and after heavy rainfall events:
a. Accumulated sediment, leaves, and trash shall be removed, and repair s made if required.
b. Inspect level spreader(s) for evidence of scour, undercutting, settlem•e it of the structure, and
concentrated flows downhill from the level spreader(s).
c. A level elevation shall be maintained across the entire flow-spreading !structure at all times.
Repair or replace the level spreader if it is damaged.
d. Mow vegetative cover to a height of six (6) inches and prune plants if t ley cover over half of the
level spreader surface.
e. Repair eroded-areas-and replace/replant•dead or damaged vegetation
2. The contractor should avoid the placement of any material on and prevent cui istruction traffic across
the structure. If the measure is damaged by construction traffic, it shall be repaired immediately.
3. Inspect and repair the collection system (e.g., catch basins, pipes, swales, ri p-ap) four (4) times a year
to maintain proper functioning.
I acknowledge and agree by my signature below that I am responsible for the per faro lance of the maintenance
procedures listed above. I agree to notify DWO of any problems with the system or E -rior to any changes to
the system or r ponsiblewrty.

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.
Provide a written description of the proposed impacts: The applicant proposes one
new road crossing. Please see the attached explanation from Withers & Ravenel of why the
impact at 313 could not be minimized further than 178' The applicant also proposes
upgrading an existing crossing of two streams The current stream crossing was constructed
more than 20 years ago and is much degraded The proposed plan will upgrade the crossing
to comply with current regulatory and stream stability requirements impacting 134 linear
feet of channel. Only 86 linear feet of channel should be considered impacted and "lost" as
bank stabilization accounts for 48 linear feet of the stream impacts resulting from the
proposed upgrade Please see XV Other Circumstances for additional information

MEMORANDUM
Date: August 3, 2005
To: Kevin Martin
From: Chris Johnson, PE
RE: Regency Parkway Extension at Renaissance at Regency Park
W&R Project No.: 204277.10
Subj: Wetland Impact Justification Statement
This memorandum contains our statement of justification for the necessity of impacting approximately 665
square feet of intermittent linear wetland at Station 70+00+1- for the purposes of constructing Regency
Parkway Extension through the Regency Park development. There is a small unimportant linear wetland
branch at this location that extends southwestward toward Barrington Park Subdivision that we are
impacting with the proposed roadway construction. We feel the need to impact this small wetland is
justified for the following reasons:
1. The Town of Cary has previously dedicated public right of way in this location set aside for the
specific purpose of extending Regency Parkway. The roadway is currently slotted as a major
thoroughfare on the Town's thoroughfare plan, which calls for a median divided roadway with
conservative horizontal and vertical design criteria. The developer has negotiated with the Town to
reduce the typical cross section to that of a minor collector roadway, which reduces the roadway
width from 72' b/b to 35' b/b and allows more flexible horizontal and vertical design criteria that
drastically reduced overall impacts to most wetland and stream channels within this project.
2. Shifting the entire road further northward in this area would greatly compromise the ability to
develop the property, as there are additional stream channels and riparian buffers within the
;adjacent site plans north of Regency Parkway. Shifting the roadway only in the immediate area of
the wetland would cause safety issues with horizontal sight distance at two proposed residential
intersections (Sta. 67+00+/- and 73 +00+/-).
3. The developer has shifted the proposed roadway approximately 25 feet northward and added a
retaining wall so as to eliminate impacts where the two upstream channels merge together just south
of this roadway. Please note this shift decreased the developable area north of the site, while
increasing the undevelopable area to the south of the roadway. Additional shifting of the roadway
will only further increase this unusable area, while further decreasing the developable area north of
the roadway.
We trust this information justifies the need to impact the wetland at Sta. 70+00.00. It is our opinion the
developer has minimized impacts to the maximum extent practical in this area and that this wetland impact
should be approved under the pending Nationwide Permit. If you have any further questions concerning
this matter, please feel free to contact us.

Upon receipt of payment, EEP will take responsibility for providing the compensatory mitigation for the permitted impacts
up to a 2:1 ratio, (buffers, Zone 1 at a 3:1 ratio and Zone 2 at a 1.5:1 ratio). The type and amount of the compensatory
mitigation will be as specified in the Section 404 Permit and/or 401 Water Quality Certification, and/or LAMA Permit. The
mitigation will be performed in accordance with the Memorandum of Understanding between the N. C. Department of
Environment and Natural Resources and the U. S. Army Corps of Engineers dated November 4, 1998.

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.
Provide a written description of the proposed impacts: _ The applicant proposes one
new road crossing. Please see the attached explanation from Withers & Ravenel of why the
impact at 3B could not be minimized further than 178' The applicant also proposes
upgrading an existing crossing of two streams. The current stream crossing was constructed
more than 20 years ago, and is much degraded. The proposed plan will upgrade the crossing
to comply with current regulatory and stream stability requirements impacting 134 linear
feet of channel. Only 86 linear feet of channel should be considered impacted and "lost" as
bank stabilization accounts for 48 linear feet of the stream impacts resulting from the
proposed upgrade Please see XV. Other Circumstances for additional infotTnation

MEMORANDUM
Date: August 3, 2005
To: Kevin Martin
From: Chris Johnson, PE
RE: Regency Parkway Extension at Renaissance at Regency Park
W&R Project No.: 204277.10
Subj: Wetland Impact Justification Statement
This memorandum contains our statement of justification for the necessity of impacting approximately 665
square feet of intermittent linear wetland at Station 70+00+/- for the purposes of constructing Regency
Parkway Extension through the Regency Park development. There is a small unimportant linear wetland
branch at this location that extends southwestward toward Barrington Park Subdivision that we are
impacting with the proposed roadway construction. We feel the need to impact this small wetland is
justified for the following reasons:
1. The Town of Cary has previously dedicated public right of way in this location set aside for the
specific purpose of extending Regency Parkway. The roadway is currently slotted as a major
thoroughfare on the Town's thoroughfare plan, which calls for a median divided roadway with
conservative horizontal and vertical design criteria. The developer has negotiated with the Town to
reduce the typical cross section to that of a minor collector roadway, which reduces the roadway
width from 72' b/b to 35' b/b and allows more flexible horizontal and vertical design criteria that
drastically reduced overall impacts to most wetland and stream channels within this project.
2. Shifting the entire road further northward in this area would greatly compromise the ability to
develop the property, as there are additional stream channels and riparian buffers within the
adjacent site plans north of Regency Parkway. Shifting the roadway only in the immediate area of
the wetland would cause safety issues with horizontal sight distance at two proposed residential
intersections (Sta. 67+00+/-and 73+00+/-).
3.: The developer has shifted the proposed roadway approximately 25 feet northward and added a
retaining wall so as to eliminate impacts where the two upstream channels merge together just south
of this roadway. Please note this shift decreased the developable area north of the site, while
increasing the undevelopable area to the south of the roadway. Additional shifting of the roadway
will only further increase this unusable area, while further decreasing the developable area north of
the roadway.
We trust this information justifies the need to impact the wetland at Sta. 70+00.00. It is our opinion the
developer has minimized impacts to the maximum extent practical in this area and that this wetland impact
should be approved under the pending Nationwide Permit. If you have any further questions concerning
this matter, please feel free to contact us.

MEMORANDUM
Date: August 3, 2005
To: Kevin Martin
From:', Chris Johnson, PE
RE: Regency Parkway Extension at Renaissance at Regency Park
W&R Project No.: 204277.10
Subj: Wetland Impact Justification Statement
This memorandum contains our statement of justification for the necessity of impacting approximately 665
square',feet of intermittent linear wetland at Station 70+00+1- for the purposes of constructing Regency
Parkway Extension through the Regency Park development. There is a small unimportant linear wetland
branch' at this location that extends southwestward toward Barrington Park Subdivision that we are
impacting with the proposed roadway construction. We feel the need to impact this small wetland is
justified for the following reasons:
1. The Town of Cary has previously dedicated public right of way in this location set aside for the
specific purpose of extending Regency Parkway. The roadway is currently slotted as a major
thoroughfare on the Town's thoroughfare plan, which calls for a median divided roadway with
conservative horizontal and vertical design criteria. The developer has negotiated with the Town to
reduce the typical cross section to that of a minor collector roadway, which reduces the roadway
width from 72' b/b to 35' b/b and allows more flexible horizontal and vertical design criteria that
drastically reduced overall impacts to most wetland and stream channels within this project.
2. Shifting the entire road further northward in this area would greatly compromise the ability to
develop the property, as there are additional stream channels and riparian buffers within the
adjacent site plans north of Regency Parkway. Shifting the roadway only in the immediate area of
the wetland would cause safety issues with horizontal sight distance at two proposed residential
intersections (Sta. 67+00+/-and 73+00+/-).
3. The developer has shifted the proposed roadway approximately 25 feet northward and added a
retaining wall so as to eliminate impacts where the two upstream channels merge together just south
of this roadway. Please note this shift decreased the developable area north of the site, while
increasing the undevelopable area to the south of the roadway. Additional shifting of the roadway
will only further increase this unusable area, while further decreasing the developable area north of
the roadway.
We trust this information justifies the need to impact the wetland at Sta. 70+00.00. It is our opinion the
developer; has minimized impacts to the maximum extent practical in this area and that this wetland impact
should be approved under the pending Nationwide Permit. If you have any further questions concerning
this matter, please feel free to contact us.

Upon receipt of payment, EEP will take responsibility for providing the compensatory mitigation for the permitted impacts
up to a 2:1 ratio, (buffers, Zone 1 at a 3:1 ratio and Zone 2 at a 1.5:1 ratio). The type and amount of the compensatory
mitigation will be as specified in the Section 404 Permit and/or 401 Water Quality Certification, and/or LAMA Permit. The
mitigation will be performed in accordance with the Memorandum of Understanding between the N. C. Department of
Environment and Natural Resources and the U. S. Army Corps of Engineers dated November 4, 1998.

MEMORANDUM
Date: August 3, 2005
To: Kevin Martin
From: Chris Johnson, PE
RE: Regency Parkway Extension at Renaissance at Regency Park
W&R Project No.: 204277.10
Subj: Wetland Impact Justification Statement
This memorandum contains our statement of justification for the necessity of impacting approximately 665
square feet of intermittent linear wetland at Station 70+00+1- for the purposes of constructing Regency
Parkway Extension through the Regency Park development. There is a small unimportant linear wetland
branch at this location that extends southwestward toward Barrington Park Subdivision that we are
impacting with the proposed roadway construction. We feel the need to impact this small wetland is
justified for the following reasons:
1. The Town of Cary has previously dedicated public right of way in this location set aside for the
specific purpose of extending Regency Parkway. The roadway is currently slotted as a major
thoroughfare on the Town's thoroughfare plan, which calls for a median divided roadway with
conservative horizontal and vertical design criteria. The developer has negotiated with the Town to
reduce the typical cross section to that of a minor collector roadway, which reduces the roadway
width from 72' b/b to 35' b/b and allows more flexible horizontal and vertical design criteria that
'drastically reduced overall impacts to most wetland and stream channels within this project.
2. Shifting the entire road further northward in this area would greatly compromise the ability to
develop the property, as there are additional stream channels and riparian buffers within the
adjacent site plans north of Regency Parkway. Shifting the roadway only in the immediate area of
the wetland would cause safety issues with horizontal sight distance at two proposed residential
intersections (Sta. 67+00+/-and 73+00+/-).
3. The developer has shifted the proposed roadway approximately 25 feet northward and added a
retaining wall so as to eliminate impacts where the two upstream channels merge together just south
of this roadway. Please note this shift decreased the developable area north of the site, while
increasing the undevelopable area to the south of the roadway. Additional shifting of the roadway
will only further increase this unusable area, while further decreasing the developable area north of
the roadway.
We trust this information justifies the need to impact the wetland at Sta. 70+00.00. It is our opinion the
developer has minimized impacts to the maximum extent practical in this area and that this wetland impact
should be approved under the pending Nationwide Permit. If you have any further questions concerning
this matter, please feel free to contact us.

litter.
AdPre-Form Scour Holes are on flat slopes only
c: No structures are located in protected buffers"
If bypass method specified in the Draft Level Spreader Design Option Document:
Bypass method is specified (i€ applicable) and plan details and calculations are provided
Discharge to level spreader and subsequent filter strip is hydraulically and spatially separate from the bypass
discharge.
`- No structures are located in protected buffers.
c. Plan details for the bypass and outlets are provided.
C<) The operation and maintenance agreement includes annual erosion and vegetation repair.
The operation and maintenance agreement signed and notarized by the responsible party is provided.
i
Level spreaders in series can be used on slopes of up to 15% in forested areas with leaf littler cover or on slopes of up to 25% in areas
with thick ground cover or grass if designed according to the Draft Level Spreader Design Option Document. This potentially requires a
minor variance in protected buffer areas. In any event the second level spreader cannot be located in Zone 1 of a protected buffer area.

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 applicant proposes one
new road crossing. Please see the attached explanation from Withers & Ravenel of why the
impact at 3B could not be minimized further than 178' The applicant also proposes
upgrading an existing crossing of two streams The current stream crossing was constructed
more than 20 years ago and is much degraded The proposed plan will upgrade the crossing
to comply with current regulatory and stream stability requirements impacting 134 linear
feet of channel. Only 86 linear feet of channel should be considered impacted and "lost" as
bank stabilization _accounts for 48 linear feet of the stream impacts resulting from the
proposed upgrade Please see XV. Other Circumstances for additional information
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-

MEMORANDUM
Date: August 3, 2005
To: Kevin Martin
From: Chris Johnson, PE
RE: Regency Parkway Extension at Renaissance at Regency Park
W&R Project No.: 204277.10
Subj: Wetland Impact Justification Statement
This memorandum contains our statement of justification for the necessity of impacting approximately 665
square feet of intermittent linear wetland at Station 70+00+1- for the purposes of constructing Regency
Parkway Extension through the Regency Park development. There is a small unimportant linear wetland
branch at this location that extends southwestward toward Barrington Park Subdivision that we are
impacting with the proposed roadway construction. We feel the need to impact this small wetland is
justified for the following reasons:
The Town of Cary has previously dedicated public right of way in this location set aside for the
specific purpose of extending Regency Parkway. The roadway is currently slotted as a major
thoroughfare on the Town's thoroughfare plan, which calls for a median divided roadway with
conservative horizontal and vertical design criteria. The developer has negotiated with the Town to
reduce the typical cross section to that of a minor collector roadway, which reduces the roadway
width from 72' b/b to 35' b/b and allows more flexible horizontal and vertical design criteria that
drastically reduced overall impacts to most wetland and stream channels within this project.
2. Shifting the entire road further northward in this area would greatly compromise the ability to
develop the property, as there are additional stream channels and riparian buffers within the
adjacent site plans north of Regency Parkway. Shifting the roadway only in the immediate area of
the wetland would cause safety issues with horizontal sight distance at two proposed residential
intersections (Sta. 67+00+/-and 73+00+/-).
3. The developer has shifted the proposed roadway approximately 25 feet northward and added a
retaining wall so as to eliminate impacts where the two upstream channels merge together just south
of this roadway. Please note this shift decreased the developable area north of the site, while
increasing the undevelopable area to the south of the roadway. Additional shifting of the roadway
will only further increase this unusable area, while further decreasing the developable area north of
the roadway.
We trust this information justifies the need to impact the wetland at Sta. 70+00.00. It is our opinion the
developer has minimized impacts to the maximum extent practical in this area and that this wetland impact
should be approved under the pending Nationwide Permit. If you have any further questions concerning
this matter, please feel free to contact us.
