Cary, NC 27513
Dear Sirs:
This 401 Water Quality Certification Approval replaces the Approval issued February 1, 1999. You have our approval, in
accordance with the attached conditions and those listed below, to place till material in an additional 949 feet of streams for the
purpose of commercial development at Arbor Investments, Inc. at Cary Parkway and Maynard Road in Cary, as you described in
your application dated January 12, 1999. After reviewing your application, we have decided that this fill is covered by General
Water Quality Certification Numbers 3103 and 3108. These certifications allow you to use Nationwide Permit Numbers 14 and
26 when the Corps of Engineers issues them. In addition, you should get any other federal, state or local permits before you go
ahead with your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and
Water Supply Water shed regulations. This approval will expire when the accompanying 404 or CAMA 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 except as modified below. 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 wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required
as described in 15A NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the
attached certification and any additional conditions listed below:
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas within
50 feet of all streams and ponds to notify the state in order to assure compliance for future wetland and/or water impact. These
mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is later).
2. An additional condition is that a final, written stormwater plan which meets an 85% TSS removal standard must be approved by
DWQ, each, for the industrial site and for the shopping center site. Additionally, each plan must receive approval from DWQ before
wetland (or stream) impacts can occur at its corresponding site. Also, each stormwater treatment facility, as indicated in the above
approved plan(s), shall be constructed and operational and all aspects of the corresponding stormwater management plan shall be
implemented before any structure is occupied that is served by that stormwater treatment facility.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter
150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-

Nationwide Permits 14 & 26
Dear Mr. Domey,
Reference our meeting at your office on November 11, 1998. Also present at this meeting was Randy
Smith of Preston Development Company; Bernie Garrett, Sam Ravenel and Tony Withers of Withers &
Ravenel, project engineers; and Todd St. John of your staff. Our purpose was to continue our on-going
discussions regarding the terms and conditions relative to completing the permitting the above-mentioned
project.
In summary, the subject project was partially authorized by your office on July 17, 1997. Because the
majority of stream impacts were to intermittent streams having relatively low biological productivity, the
stream mitigation plan submitted with the application was determined to not be required. Additionally,
subsequent discussions have determined the project is "vested" in regards to the Neuse River Buffer
Rules and said rules are not applicable. The purpose of this most recent meeting was for the engineers
to discuss specific plans for meeting 85% reduction in total solids for stormwater discharge. Said
reduction has been indicated as a requirement for 401 Certification approval.
Attached are the conceptual plans for meeting the stormwater requirement. The plan entitled "Preston
East Industrial Park, Cary, NC" shows the overall stormwater management plan for parcels 1 through 16
adjacent to Tower Court and James Jackson Avenue. A second drawing entitled "Preston East Planning"
denotes the conceptual plan for the shopping center parcel located in the southeastern comer of the
intersection of Cary Parkway and James Jackson Avenue. The stormwater detention basins proposed in
these plans should address the requirements of your office necessary for 401 Certification.
The construction of these basins will impact approximately 2370 square feet or 0.054 acre of intermittent
stream channel having relatively low biological productivity. Total project impacts are approximately 8080
square feet or 0.185 acre. A table providing a summary of the project impacts is attached.

Dear Mr. Alsmeyer,
This letter is to request concurrence with an amendment to permits issued previously for the above-
mentioned project. Based on discussions with the North Carolina Division of Water Quality, it has been
determined stormwater detention basins are required meet water quality standards for State 401
certification.
The construction of these basins will result in additional impacts of approximately 2370 square feet or
0.054 acre. These impacts will be to intermittent stream channels of relatively low biological productivity.
Total project impacts (including previously-permitted impacts associated with Nationwide Permit 14 road
crossings) are approximately 8080 square feet or 0.185 acre. A table providing a summary of the project
impacts is attached, as are figures showing the proposed stormwater detention basin areas.
Please provide us with written concurrence regarding this request. Should you have any questions

This letter will confirm our telephone conversation this morning regarding the above-mentioned project.
Our discussion primarily pertained to the tlming of the development authorized by the 401 Certification
issued by DWQ on February 1, 1999.
The project is being developed in two large segments. These segments are the Industrial park and the
shopping center. The industrial park is a subdivision and the shopping center will be developed as a
single parcel. At this time, the owners have instructed the engineers to proceed with the development of
a stormwater plan for the industrial park as specified in Condition Number 2 of the 401 Certification.
This will be submitted to your office for review in the near future. Additional planning must be
undertaken prior to the development of a stormwater plan for the shopping center segment of the
property-
Condition Number 2 specifies the following:
"2. An additional condition is that a final, written stormwater plan which meets an 85%
TSS removal standard must be approved by DWQ before wetland (or stream) impacts
occur. Also, within 5 months of receipt of this fetter, the stormwater treatment facilities
shall be constructed and operational and the stormwater management plan be
Implemented."
Due to the construction sequence of the various segments of the property proposed by the owners,
compliance with the timing aspects of this condition Is not possible. The owners would like to request
this condition be modified to read

APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Arbor Investments, LLC
1005 High House Road
Cary, NC 27513
Dear Sirs:
You have our approval, in accordance with the attached conditions and those listed below, to place fill material in an
additional 949 feet of streams for the purpose of commercial development at Arbor Investments, Inc. at Cary Parkway and
Maynard Road in Cary, as you described in your application dated January 12, 1999. After reviewing your application, we have
decided that this fill is covered by General Water Quality Certification Numbers 3103 and 3108. These certifications allow you to
use Nationwide Permit Numbers 14 and 26 when the Corps of Engineers issues them. In addition, you should get any other
federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control,
Coastal Stormwater, Non-Discharge and Water Supply Water shed regulations. This approval will expire when the
accompanying 404 or CAMA 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 except as modified below. 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 wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required
as described in 15A NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the
attached certification and any additional conditions listed below.
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas within
50 feet of all streams and ponds to notify the state in order to assure compliance for future wetland and/or water impact. These
mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is later).
2. An additional condition is that a final, written stormwater plan which meets an 85% TSS removal standard must be approved by
DWQ before wetland (or stream) impacts occur. Also, within 6 months of receipt of this letter, the stormwater treatment facilities shall

To: John Dorney <[e-mail]. nc.us>
As you may recall, Nelson Paul just contacted us regarding this project. He requested that we change the
language in the 401 Certification to not require final written approval for a stormwater managment plan
before the impacts can occur. I just received a call from the engineer, Bernie Garrett (469-3340), during
which he told me that they (as a firm) we only requested to provide adequate locations and sizing for the
stormwater BMPs, which they did and we approved. He advised me that each BMP will be designed and
built by the individual parcel owners. Therefore, as far as he knows there are no final plans yet. If this is
the case, it may be reasonable not to require final plans at this time, but we could require final plans as
the "watershed" for each parcel begins development and completion and implementation before the first
to he served by each storr.,,,vater P.MP i s c,?^structed. If the developer ba!ks at such a ~Mric_
then they should be required to abide by the current 401. In any event, it may be best (ie easiest for
me) if we simply require that the developer (and not the parcel owners) to design and obtain
-ach BMP and that •..,? ...•n.,4 ?r ._. se-?; !::^.? of time extensiop in :,
;?.:coinpiish this... i would not like to go tr._ ?agii some piece-meal thing again... then we w,,uici
require the the plan be built and implemented before the first building served by that BMP is
Ocenpied.
let me know what you think and i will call the engineer hack...

1.0 INTRODUCTION AND PROJECT PURPOSE
' The purpose of this document is to propose a plan for compensatory mitigation
of stream impacts associated with the development of the Arbor Investments,
L.L.C. property located in Cary, North Carolina (herein afterwards referred to as
' the "Property").
' The proximity of the Town of Cary to major employment, transportation,
recreation and educational facilities makes it one of the fastest growing cities in
the State of North Carolina. The Town of Cary is dependent on private
' development initiatives to meet the residential, retail and recreational demands
of the growing population. The Town of Cary implements strict zoning
restrictions that control the engineering and aesthetics of this growth in a
' planned and thoughtful manner. Arbor Investments, L.L.C., a private
development initiative, is proposing to meet some of the demand pressures of
the growing residential and commercial sectors by the developing the Property
' with a diversity of uses, including light industrial, multi-family residential, single-
family residential and commercial uses.
' The project purpose is to construct the infrastructure necessary to develop the
Property for diverse uses, including light industrial, multi-family residential,
single-family residential and commercial uses. These land uses are those
' typically provided by private commercial developers to meet the needs of private
citizens and private businesses.
' The intention of the stream mitigation outlined by this plan is to construct a
substitute stream channel that will compensate for the stream channels
segments that will be altered by project activities conducted under Nationwide
' Permit (NWP) 26. Regional conditions imposed by the U.S. Army Corps of
Engineers, Wilmington District Regulatory Branch, dated May 15, 1997, require
applicants provide notification to the Wilmington District Engineer and receive
1 written approval prior to performing work that would impact more than 150 feet of
a stream. Notification will include the location of work, a description of work, a
' discussion of alternatives to working in the stream and why alternatives were not
selected, and a plan to mitigate for all avoidable adverse impacts to more than
150 linear feet of the stream.

1

This plan for stream mitigation is to construct 350 of new stream channel for the
500 feet of stream channel proposed to be altered as required by the federal
regional guidelines that pertain to NWP 26. Other impacts described in this
stream mitigation plan do not require mitigation but are provided for the sake of
completeness. Adverse impacts of the other impacts of the project (NWP 14
activities) are considered to be no more than minimal and that the aquatic
environment will be protected.
rJ (

I

This plan is to provide information for evaluation of the proposed stream
mitigation by the natural resource agencies and is to also serve as a guidance
document for future detailed engineering, construction and monitoring of the
created stream segment.

2.0 NOTIFICATION REQUIREMENTS
2.1 Location of Work and Property Description
¦ The Property is a tract approximately 120 acres in size located between the
proposed Cary Parkway and Maynard Road in the Town of Cary, Wake County,
I North Carolina (see Figure 1 - Site Location Map, Arbor Investments, L.L.C.
Property).
' The Property is typical of properties in the Piedmont geographical province. The
Property is moderately eroded and dissected with a significant drainage system.
I Vegetation consists of mature hardwoods, except in the central portion of the
property, north of Coles Branch, and in portions of the floodplain south of Coles
Branch. Here the Property is vegetated with young pines and mixed hardwoods.
' The WKIX antennae site is grassed. Overall, development of the Property will
entail relatively minor environmental impacts.
' Coles Branch is a significant environmental feature of the Property. Coles
Branch traverses the Property from the east to west and consists of a narrow
perennial stream and flood plain. The Town of Cary restricts development
' within floodplains and no construction or development activities (with the
exception of this proposed stream mitigation) are proposed by Arbor
Investments, L.L.C. within the Coles Branch floodplain.
I The waters and wetlands of the site have been delineated and surveyed. The
waters and wetland locations have been verified by the U.S. Army Corps of
' Engineers. Wetlands and waters on the Property account for an insignificant
amount of the total land area. The project avoids wetland impacts entirely.
' 2.2 Description of Work
I The project will involve the construction of the infrastructure necessary to
develop the Property for diverse uses, including light industrial, multi-family
residential, single-family residential and commercial uses. The impacts of the
' project are to "Waters of the United States" primarily from several minor road

3.0 DISCUSSION OF ALTERNATIVES TO THE PROPOSAL

C

The selection of this Property consisted of a process involving the evaluation
and consideration of various engineering, economic and environmental factors.
The principal controlling factors considered in proposing the utilization of the
Property for the proposed project activities are as follows:
Ownership. The Property is under the ownership of Arbor Investments,
L.L.C. The Property was purchased for development purposes. The
proposed impacts are the minimal necessary for economical development of
the Property in accordance with the owner's investment-backed expectations.
Location. The Property is located within the Town of Cary adjacent to
developed tracts. The Property is proposed to be traversed by major
transportation arteries. A major thoroughfare (Cary Parkway extension) has
been proposed and is under consideration for construction that will border
the western portion of the Property. The Property itself will be traversed by
James Jackson Avenue (included as a portion of the proposed development
for the Property in this application) which will connect the proposed Cary
Parkway extension with North Maynard Road. Each of the public
thoroughfares mentioned are part of the approved thoroughfare plan for the
Town of Cary, which was approved by the Town and the NC Department of
Transportation.
Availability of Public Utilities. Water, sewer and natural gas are available at
the Property. Previous public investment was made in the installation of
these services in logical anticipation of future site development.
' Since the stream impacts proposed under NWP 26 at the commercial retail
project south of James Jackson Avenue are the only stream impacts being
mitigated for in this plan, this alternatives discussion will focus on the stream
' impacts surrounding this aspect of the project. The stream impacts of the
commercial retail project consist primarily of fills for parking lot construction.
' Alternative parking lot configurations at the commercial retail project have been
considered and where feasible, modifications have been made to the proposed
project design. The use of bridges for the parking lots was judged to be
' impractical and economically unfeasible. The use of retaining walls to contain

parking lot side-slope fills was judged to create a safety issue, in addition to
being impractical and economically unfeasible for both initial construction and
long-term maintenance. The "no-build" alternative was also considered and
rejected as it would not meet the project purpose. Additionally, the "no-build"
alternative would not be in the public interest because the location of the project
has the potential of serving a large population base with needed services (i.e.
food, pharmacy, offices, etc.).
There are no alternative sites for the commercial retail project that have the
ownership, zoning, location or the availability of public services that would meet
the project purpose and have significantly less impacts. The design of the
proposed commercial retail project minimizes water and wetland impacts to the
maximum extent possible while still meeting the project purpose. The following
section describes the measures that will be employed in providing compensatory
mitigation for the intermittent stream impacts.

4.0 PLAN TO MITIGATE FOR STREAM IMPACTS
4.1 Stream Characterization
Intermittent streams on the Property are generally characterized by shallow,
narrow, eroded channels approximately three (3) feet deep, with a base of
approximately two (2) feet and a top width of approximately four (4) feet. The
stream channels are relatively straight in plan view and have occasional riffle
and pool sequences within the stream beds. Some stream segments appeared
to be relic agricultural ditches due to their extreme linear nature and lack of any
definable riffle and pool sections. The stream banks are typically stabilized by a
growth of mixed hardwoods and pines that vary in age from shrubs and saplings
to mature trees.
4.2 Stream Mitigation Site Description
The stream mitigation site (see Figure 11, Site Map, Stream Mitigation Project) is
located within the floodplain of Coles Branch. The site is vegetated with shrub
and sapling species that include mixed hardwoods and pines. Soils are alluvial
sediment deposits from Coles Branch.
4.3 Stream Mitigation Concept
The stream mitigation concept will involve the construction of an intermittent
stream channel supplied with stormwater during rainfall events from the adjacent
commercial retail project. The constructed stream channel will roughly parallel
Coles Branch, in order to prevent the discharge of sediment into the constructed
stream during high-flow events.
The project construction sequence will minimize disturbance to vegetation as
much as possible in gaining access to the site by hand clearing or utilizing a
mower to clear the proposed stream corridor. Material from the channel
excavation will be widely distributed to allow secondary growth of the indigenous
vegetation from the existing roots and to reduce the possibility of the spoil
material eroding back into the constructed stream channel.
Rock material from offsite consisting of a mixture of rock sizes (2-18 inch) will be
used to construct the riffle and pool sequences in accordance with state
ECPS Project No. 0006-001 Page - 10

ENIZI40AG1/ENTAC CONSULT.Q/Y73'?/YPfF/4A//TS/?LYAL/S7S
guidelines. The stream development will be monitored after completion for
vegetation growth and sedimentation.
4.4 Stream Mitigation Site Modifications
The proposed site modifications will begin with a sediment basin at the upper
end of the proposed stream channel construction. The sediment basin is to be
installed as part of the site clearing operations for the proposed retail center.
The sediment basin will be designed to remain after construction of the
proposed retail center is completed and its discharge will form the upper-most
point of the proposed stream mitigation. Stormwater from the buildings and
parking areas of the westernmost portion of the shopping center will provide
intermittent flow to the constructed stream. The drainage area is calculated to
be 3.2 acres. Runoff calculations have been prepared by Withers & Ravenel
and are included in the Appendix of this report.
The proposed site modifications (see Figures 12 and 13) for the constructed
stream channel will include a construction sequence that will minimize impacts to
existing vegetation and unnecessary disruption to soils. This will be
accomplished by either hand clearing existing vegetation or utilizing a mower, as
site conditions allow, in the mitigation area. Clearing of the vegetation will
involve cutting the existing plants to the roots but leaving the roots intact.
Cuttings will be piled in portions of the cleared area away from the proposed
stream route.
Once the stream channel corridor is cleared of vegetation, the site will be
accessed with rubber-tired equipment, such as a backhoe or a bobcat. The
equipment will excavate the channel in accordance with the sizes indicated in
Figure 13. Spoil from the excavation will be placed in alternate piles on either
side of the channel excavation and leveled as much as possible with the
equipment bucket. Every attempt will be made to spread the spoil from the
excavation thin enough so the indigenous vegetation will redevelop.
Following the excavation, the pool and riffle breaks will be installed in
accordance with the specifications outlined in Figure 13. The material utilized to
form the pool and riffle steps will be brought into the site utilizing rubber-tired
equipment and positioned by hand.

5.0 MITIGATION REMEDIATION AND SECURITY
5.1 Mitigation Monitoring
The constructed stream segment will be monitored upon completion for a period
of three years for vegetation establishment (bank stabilization) and
sedimentation levels. Regular, inspections of the site will be conducted by a
consultant hired by Arbor Investments, L.L.C. on a yearly basis and a brief letter
will be provided to the U.S. Army Corps of Engineers regarding the inspection
observations. The inspection letter will provide information regarding the height
of the previously-disturbed vegetation and will provide information regarding the
level of sedimentation or down-cutting taking place in the constructed stream.
Any other information deemed important by the consultant will be provided in this
letter also.
5.2 Mitigation Area Remediation
Mitigation monitoring letters described in Section 5.1 will include suggested
remedial measures if the inspection indicates such measures may be required.
If it is noted the stream mitigation is performing unsatisfactorily, the consultant
and the Arbor Investments, L.L.C. managers will provide a best professional
judgment regarding the reason(s) for the unsatisfactory performance. The
consultant and the Arbor Investments, L.L.C. managers may also suggest
remedial measures to correct the deficiency in the mitigation area. Remedial
measures will be evaluated in consideration of the performance standards
outlined in Section 5.1.
Where the mitigation monitoring reports identify no deficiencies in the mitigation
area performance and include no recommendations for remedial measures, no
response from the principal state and federal wetland resource authorities within
30 days will be considered acceptance of the site progress for the pertinent
monitoring interval. In the event the mitigation monitoring report includes a
recommendation for remedial measures, the principal state and federal wetland
resource authorities will provide concurrence or an independent
recommendation within 30 days of submittal of the mitigation monitoring report.

5.3 Mitigation Security
The mitigation site is currently owned by Arbor Investments, L.L.C.. Should the
surrounding properties be sold in the future, Arbor Investments, L.L.C. will
retain a maintenance easement on the site for the duration of the mitigation
monitoring period. Arbor Investments, L.L.C. will convey, as part of the property
parcel, the stream mitigation and the buffer zone area. At the end of the
monitoring period maintenance of this stream mitigation will convey to the
buyers.

RE: James Jackson Shopping Center
Wetlands Mitigation
' Dear Randy:
' This letter is in reference to the design of the channel mitigation to compensate for wetlands
impacts at the reference site.
' Our design criteria was based on Nelson Paul's memo to Tony, dated 5/22/97.
Summarizing our design parameters, we computed a 2 year peak discharge of 15 CFS for a
' 3.2 acre drainage area assuming a runoff curve number of 95. Our storm distribution was the
SCS type 2 rainfall distribution with an antecedent moisture condition 2.
' We designed the channel to just overflow during the two year storm as opposed to the typical
design which would put freeboard to prevent overflowing during the specified design storm.
The intent here is to have "out of bank" flow and to create a low velocity meandering channel
which will improve water quality and mitigate the loss of wetlands. I have assumed a design
depth of 1' for three different channel slopes allowing the bottom width to vary with the slope.
' You will want to do a preliminary layout to determine what slope to excavate the channel on.
The following will hold true for a depth of 1' and a mannings "n" of .030 and 2.5:1 side
slopes:
' DEPTH SLOPE(%) BOTTOM WIDTH (FEET)
' 1.0 0.5 3.1
1.0 1.0 1.8
1.0 2.0 0.8

r
' The channel should be lined with "Enkamat" 7020 to allow stabilization with vegetation. The
vegetation should be a wetlands variety to be selected by Nelson Paul. If the depth I am
showing does not work out, please notify me and I will generate some additional channel
sections for other depths or slopes.
' Sincerely,
' 4amu,-l . Ravenel, PE

Tony, I have checked with the COE regarding the guidance on stream mitigation. Ken Jolly Indicated the state
guldellnes would be fine for now In their consideration of the stream mitigation plan.
State guidelines Indicate the stream channel cross-ceetlon should be designed to Carry no more than the 2-year,
24 hour storm. Pool to riffle sequence should be spaced at 5 to 7 times the channel width and pools are
generally two times deeper than the riffle area. In order to prevent the increased cost of streambank restoration
(and potential failure of the mitigation), prior to constructing the stream mttlgatlon, the area should be mowed or
cleared by hand. It may be that the constructed stream channel could be plowed into the substrate or either
excavated with a rubber-tired backhoe. We may need to discuss where and how the fill Is to be placed If the latter
alternative Is utilized. State guidance Indicates the use of tiptop should be minimized.
Call me if you have any questions. Nelson.

Dear Mr. Smith:
Please reference the April 8, 1997 permit application,
submitted on your behalf by Mr. Nelson G. Paul of Environmental
Consultants and Permit Specialists, for Department of the Army
(DA) approval to discharge fill material over 0.03 acre of
jurisdictional waters (bank-to-bank tributaries) of the United
States for the proposed construction of the James Jackson Avenue
extension, from existing James Jackson Avenue west to the
proposed Cary Parkway connector, associated with your future
commercial development on the adjacent property. This proposed
development, containing 192.3 acres, is located adjacent to and
above the headwaters of Coles Branch, in Cary, Wake County, North
Carolina.
The application you have submitted does not include the
anticipated impacts associated with the proposed construction of
the adjacent, related commercial development. We would
anticipate that adverse environmental impacts will occur as a
result of additional fills within jurisdictional waters and/or
wetlands associated with this project. Our regulations, (Title
33 of the Code of Federal Regulations, Part 325), outline
processing procedures for a Department of the Army (DA) permit.
We are required to look at "all activities which the applicant
plans to undertake which are reasonably related to the same
project and for which a DA permit would be required... District
Engineers should reject, as incomplete, any permit application

' which fails to comply with this requirement." In addition,
pursuant to December 13, 1996 Federal Register, Final Notice of
t Issuance, Reissuance, and Modification of Nationwide Permits (61
FR 65874), General Condition 13(b)(3), notification to the
District Engineer must include "any other NWP(s), regional
' general permit(s) or individual permit(s) used or intended to be
used to authorize any part of the proposed project or any related
activity."
Mr. Eric Alsmeyer of my regulatory staff verbally explained
our concerns to Mr. Paul during their telephone conversation of
May 8, 1997. He outlined the fact that we have determined that
the commercial development is reasonably related to the proposed
road. In addition, based upon all information available to us at
' this time, we would have to consider the entire commercial
development to be a single and complete project, the segmentation
' of which would preclude reasonable and feasible alternatives for
minimization and avoidance of wetland impacts for the portions
requiring an individual permit. Based upon our conclusions, you
are notified that the application you have submitted is not
complete and therefore cannot be processed at this time. You are
advised to re-evaluate the manner in which you have applied for
' our approval and to resubmit the application with all required
information. We will commence the processing of your application
upon receipt of all complete and accurate information regarding
' the additional jurisdictional activities associated with the
project.
' Please note that the following information will likely apply
to the proposed project, particularly if your complete
t application involves an individual DA permit. On November 15,
1989, the Department of the Army and the U.S. Environmental
Protection Agency signed a memorandum of agreement (MOA)
' establishing procedures to determine the type and level of
mitigation necessary to comply with the Clean Water Act, Section
404(b)(1) Guidelines. This MOA, which became effective on
' February 6, 1990, provides for (1) avoiding impacts to waters and
wetlands through the selection of the least damaging, practicable
alternative; (2) taking appropriate and practicable steps to
' minimize impacts to waters and wetlands; and (3) compensating for
any remaining unavoidable impacts to the maximum extent

2

' practicable and appropriate. To enable the Regulatory Branch to
process a permit application in full compliance with this MOA,
the following additional information should be provided with any
application:
a. Permits are available only for work dependent upon being
located within an aquatic site and being the least
environmentally damaging, practicable alternative. Information
' (alternatives analysis) regarding any other practicable
alternatives, including upland alternatives, to the work for
which you may apply must be provided, as well as justification
' that your selected plan is the least damaging to waters and/or
wetland areas.
' b. It is necessary for you to have taken all appropriate and
practicable steps to minimize wetland losses. Please indicate
' all that you have done, especially regarding development and
modification of plans and proposed construction techniques, to
minimize adverse impacts.
' c. The MOA then states that appropriate and practicable
mitigation will be required for all unavoidable adverse impacts
' remaining after practicable minimization has been employed.
Please outline your plan to mitigate for the projected,
unavoidable losses of waters and/or wetlands, or provide
' information as to the absence of any such appropriate and
practicable measures.
Any questions or comments, as well as your complete
Department of the Army permit package, should be addressed to
' Mr. Alsmeyer at telephone [phone], extension 23.

Dear Sirs:
' On 4 April 1997, you applied to the N.C. Division of Water Quality (DWQ) for a 401 Water Quality
Certification to impact 360 linear feet of waters for your project (James Jackson Ave.) located at North
Maynard Road and Cary Parkway in Wake County. Your project has been forwarded to Mr. Danny Smith
' [phone] of DWQ Raleigh Regional Office for review. This review will likely require an on-site
inspection prior to the approval, modification or denial of your project site. If you have sent additional
information to the U.S. Army Corps of Engineers concerning this project, please be certain that our staff
have copies of this material so we can use it in our process in making a decision.

I

According to our preliminary, in-house review since you propose to disturb greater than 150 linear feet
of streams, it is likely that compensatory mitigation will be required by DWQ for this project as described
in 15A NCAC 2H.0506 (b)(6). Our Regional Office staff can make this decision during their site visit. If
adequate mitigation is required but not provided, this project will likely have to be denied. If stream
mitigation is needed, the wetland Restoration Program can satisfy this requirement at $125 per linear foot of
stream. Otherwise you will have to identify a suitable mitigation site and develop an approvable mitigation
plan. Also if a mitigation plan is required, we will place this project on hold until its receipt in our Central
Office. Enclosed are materials describing compensatory mitigation requirements for this program. Please
call me at 919-733-1786 to discuss these matters if necessary. Until a mitigation plan is provided, this
application is considered to be incomplete and our processing time will not start.
We recommend that you not impact any wetlands or waters on your project site until a 401 Water
Quality Certification has been issued from Raleigh, The issuance of a Corps of Engineers 404 Permit does
not mean that your project can proceed. According to the Clean Water Act, the 404 Permit is not valid
until a 401 Certification is also issued. If DWQ staff observe impacts which are not allowable, you will be
required to remove the fill and restore the site to its original condition. I can be reached at 919-733-1786 if
you have any questions about the 401 Certification process.

Nationwide Permits 14 & 26
Dear Mr. Dorney,
Reference our meeting at your office on November 11, 1998. Also present at this meeting was Randy
Smith of Preston Development Company; Bernie Garrett, Sam Ravenel and Tony Withers of Withers &
Ravenel, project engineers; and Todd St. John of your staff. Our purpose was to continue our on-going
discussions regarding the terms and conditions relative to completing the permitting the above-mentioned
project.
In summary, the subject project was partially authorized by your office on July 17, 1997. Because the
majority of stream impacts were to intermittent streams having relatively low biological productivity, the
stream mitigation plan submitted with the application was determined to not be required. Additionally,
subsequent discussions have determined the project is "vested" in regards to the Neuse River Buffer
Rules and said rules are not applicable. The purpose of this most recent meeting was for the engineers
to discuss specific plans for meeting 85% reduction in total solids for stormwater discharge. Said
reduction has been indicated as a requirement for 401 Certification approval.
Attached are the conceptual plans for meeting the stormwater requirement. The plan entitled "Preston
East Industrial Park, Cary, NC" shows the overall stormwater management plan for parcels 1 through 16
adjacent to Tower Court and James Jackson Avenue. A second drawing entitled "Preston East Planning"
denotes the conceptual plan for the shopping center parcel located in the southeastern corner of the
intersection of Cary Parkway and James Jackson Avenue. The stormwater detention basins proposed in
these plans should address the requirements of your office necessary for 401 Certification.
The construction of these basins will impact approximately 2370 square feet or 0.054 acre of intermittent
stream channel having relatively low biological productivity. Total project impacts are approximately 8080
square feet or 0.185 acre. A table providing a summary of the project impacts is attached.

Nationwide Permits 14 & 26
Dear Mr. Alsmeyer,
This letter is to request concurrence with an amendment to permits issued previously for the above-
mentioned project. Based on discussions with the North Carolina Division of Water Quality, it has been
determined stormwater detention basins are required meet water quality standards for State 401
certification.
The construction of these basins will result in additional impacts of approximately 2370 square feet or
0.054 acre. These impacts will be to intermittent stream channels of relatively low biological productivity.
Total project impacts (including previously-permitted impacts associated with Nationwide Permit 14 road
crossings) are approximately 8080 square feet or 0.185 acre. A table providing a summary of the project
impacts is attached, as are figures showing the proposed stormwater detention basin areas.
Please provide us with written concurrence regarding this request. Should you have any questions
regarding this or any other related matter, please feel free to contact me at [phone].
Cordially yours,
ECPS, Inc.

Dear Mr. Smith:
Re: Neuse River buffer rules
Arbor Investments, LLC project
DWQ # 970326
Wake County
As we discussed at our meeting on September 14, 1998, DWQ has determined
that this project at Cary Parkway and Maynard Road has vested rights for the Neuse
River buffer rules since DWQ issued a 401 Water Quality Certification for road crossings
for this project on July 17, 1997. As you are aware, an amended 401 Certification will be
required for the additional stream impact described in your June 1997 submittal including
a stormwater management plan. However this additional impact will not jeopardize this
vested status.
Please call me at 919-733-1786 if you have any questions.

During the 5/5/97 site visit, it was determined by RRO staff that _
the proposed 360 feet of total impacts will occur in an
intermittent stream. It is not believed that this is a positive _
7Q10/30Q2 stream. In addition, with the exception of a single
_ crayfish, some waterstriders, and algae/periphyton, there are-
likely no "significant" aquatic uses in place. However, the 401 .
should be issued with the following conditions: 1) side slopes-
should be 3:1 or greater to minimize impacts.

As I related to you this morning by telephone, I posed the situation outlined in my previous memo to

Ms. Gaddis said that Mr. Domey indicated we are to follow the ammended application.
Including this conversation, the way I understand the permit is we are authorized to conduct the
development activities outlined herein, minus the proposed mitigation.
With this in mind, I will be checking on the applicability of Neuse River buffers. Feel free to call if you

James Jackson Avenue
Federal and State Approvals
Date: August 20, 1998
As we discussed this morning, I have reviewed the applications and approvals we received regarding the
James Jackson Avenue Project.
As you may recall, we initially submitted an application on April 8, 1997 for a Nationwide Permit (NWP)
14 to authorize the road crossings associated with James Jackson Avenue. This application was
subsequently put on hold by the US Army Corps of Engineers (COE) by letter dated May 8. 1997. The
COE required that the permit application be amended to include arty development that is'Yeasonabiy
related to the proposed road Addtionady, the COE letter indicated that they `could have to consider
the entire commercial development to be a single and complete project, the segmentation of which
would preclude reasonable and feasible attematives for minimization and avoicance of vwedland impacts
for the portions requiring an individual permit". Copies of the letter were sert io the State Wetlands
Group (who issue 401 Certifications).
As you may also recall, you and I met viM the State Wetlands Group (specificady John Domey, Eric
DeLamb, Cindy Bell and Danny Smith) ad the Wetlands Group offices on May 7, 1997 to aiscuss the
specific project. During this meeting vo-- discussed vrhen stream rritigation vow required and the options
of stream mitigation. Subsequently, an on-site meeting ocxcured vith Eric Fieece, who determined
some stream segments on the property to be intermittent and some to be perennial. Our subsequent
application offered stream mitigation for M the impacted peremia stream sep-.ents. Because the state
did not feel the impacted perennial stream segmerts supported any significxint marine life, the mitigation
we later provided was not required. Adddonally, prior to submitting the amerded application showing
the complete site development proposal and mitigaii , plan for the total prvje- impacts, vw met with
Eric Alysmyer of the COE in his office (play 20, 1997) to discuss specifically vtmt would be required in
this package.
Because the agencies required a drscksxe of the plans for the toad development, the amended
application specified it vras an appl" n for both NV#V 14 and MVP 26. The addition of NWP 26 wes
necessitated by the increased deveiio? impacts a-amciated vAh the total project disclosure required
by the COE. Clearly the COE undue this in issu[inQ their auftrization dated July 16, 1997.
The State, on the other hand, must nct tave read the amended apg6cetion veq carefully. Their letter of
July 17, 1997 discusses orfy a 401 ce Mcation for MVP 14 for Jaynes Jacksan Avenue, but at the same
time, references the revised June perme amendmer
In conclusion, we made arpptication for s;ecific permbs that were rot acted on by the state- State
regulations require the state to ad on xrAications wiMin a specific period of ti'ae, but I am going to
have to defer to your attorney as to vt.e tier the ad'difcnal NWP 14 and NWP 25 aspects of the
amended application fall under the "vairsr of certficadon" outfi )ed in NCAC !5k 02H .0507 (a).

Indicaie Which of the following apply:
X There are wetlands on the above described property which have been delineated and which we strongly suggest
be surveyed. The surveyed wetland lines must be verified by our staff before the Corps will make a final
jurisdictional determination on your property.
Because of the size of your property and our present workload, our identification and delineation of your
wetlands cannot be accomplished in a timely manner. You may wish to employ a consultant to obtain a more
timely delineation of the wetlands. Once your consultant has flagged a wetland line on the property, Corps
staff will review it, and, if it is accurate, we strongly recommend that you have the line surveyed for final
approval by the Corps. The Corps will not make a final jurisdictional determination on your property without
an approved survey.
X The wetlands on your lot have been delineated, and the limits of Corps jurisdiction have been explained to
you. Unless there is a change in the law or our published regulations, this determination may be relied upon
for a period not to exceed five years from the date of this notification.
_ There are no wetlands present on the above described property which are subject to the permit requirements of

Nelson Paul (consultant for this project) called with some information with regard to this
project. Originally the Corps of Engineers was going to require mitigation so Nelson prepared the
enclosed mitigation plan. However (apparently) the COE will not now require mitigation. I
assured Nelson that we would make a decision regarding the need for mitigation based on our
rules regardless of whether it was "offered". Please review the project in our normal manner. If
our rules would require mitigation, then the enclosed plan is relevant. If our rules would not
require mitigation, then please ignore that part of the application.

Dear Mr. Smith:
Please reference the April 8, 1997 permit application,
submitted on your behalf by Mr. Nelson G. Paul of Environmental
Consultants and Permit Specialists, for Department of the Army
(DA) approval to discharge 'Lill material over 0.03 acre of
jurisdictional waters (bank-to-bank tributaries) of the United
States for the proposed construction of the James Jackson Avenue
extension, from existing James Jackson Avenue west to the
proposed Cary Parkway connector, associated with your future
commercial development on the adjacent property. This proposed
development, containing 192.3 acres, is located adjacent to and
above the headwaters of Coles Branch, in Cary, Wake County, North
Carolina.
The application you have submitted does not include the
anticipated impacts associated with the proposed construction of
the adjacent, related commercial development. We would
anticipate that adverse environmental impacts will occur as a
result of additional fills within jurisdictional waters and/or
wetlands associated with this project. Our regulations, (Title
33 of the Code of Federal Regulations, Part 325), outline
processing procedures for a Department of the Army (DA) permit.
We are required to look at "all activities which the applicant
plans to undertake which are reasonably related to the same
project and for which a DA permit would be required... District
Engineers should reject, as incomplete, any permit application
50' ,
which fails to comply with this requirement." In addition,
pursuant to December 13, 1996 Federal Register, Final Notice of
Issuance, Reissuance, and Modification of Nationwide Permits (61
FR 65874), General Condition 13(b)(3), notification to the
District Engineer must include "any other NWP(s), regional
general permit(s) or individual permit(s) used or intended to be
used to authorize any part of the proposed project or any related
activity."
Mr. Eric Alsmeyer of my regulatory staff verbally explained
our concerns to Mr. Paul during their telephone conversation of
May 8, 1997. He outlined the fact that we have determined that
the commercial development is reasonably related to the prcposed
road. In-addition, based upon all information available to us at
this time, we would have to consider the entire co-mmercial
development to be a single and complete project, the segmentation
of which would preclude reasonable and feasible alternatives for
minimization and avoidance of wetland impacts for the portions
requiring an individual permit. Based upon our conclusions, you
are notified that the application you have submitted is nct
complete and therefore cannot be processed at this time. _-ou are
advised to re-evaluate the manner in which you have appli=d for
our approval and to resubmit the applicaticn with all rec-i:ired
information. We will comrence the processing of your application
upon receipt of all complete and accurate informaticn regarding
the additional jurisdicticnal activities associated with
project.
Please note that the fc;llowina information will likely apply
to the proposed project, particularly if ycur complete
application involves an individual DA permit. On Vovember 15,
1989, the Department of the Army and the U.S. Environmental
Protection Agency signed a memorandum of agreement (MOA)
establishing procedures to determine the type and level of
mitigation necessary to cc=ly with the Clean Water Act, S-ection
404(b)(1) Guidelines. This MOA, which became effective on
February 6, 1990, provides for (1) avoiding impacts to waters and
wetlands through the selection of the least damaging, practicable
alternative; (2) taking appropriate and practicable steps to
minimize impacts to waters and wetlands; and (3) co=ensasing for
any remaining unavoidable .pacts to the maximum extent
2
practicable and appropriate. To enable the Regulatory Branch to
process a permit application in full compliance with this MOA,
the following additional information should be provided with any
application:
a. Permits are available only for work dependent upon being
located within an aquatic site and being the least
environmentally damaging, practicable alternative. Information
(alternatives analysis) regarding any other practicable
alternatives, including upland alternatives, to the work for
which you may apply must be provided, as well as justification
that your selected plan is the least damaging to waters and/or
wetland areas.
b. It is necessary for you to have taken all appropriate and
practicable steps to minimize wetland losses. Please indicate
all that you have done, especially regarding development and
modification of plans and proposed construction techniques, to
minimize adverse impacts.
C. The MOA then states that appropriate and practicable
mitigation will be required for all unavoidable adverse impacts
remaining after practicable minimization has been employed.
Please outline your plan to mitigate for the projected,
unavoidable losses of waters and/or wetlands, or provide
information as to the absence of any such appropriate and
practicable measures.
Any questions or comments, as well as your complete
Department of the Army permit package, should be addressed to
Mr. Alsmeyer at telephone [phone], extension 23.

DWQ #970326
Wake County
On 4 April 1997, you applied to the N.C. Division of Water Quality (DWQ) for a 401 Water Quality
Certification to impact 360 linear feet of waters for your project (James Jackson Ave.) located at North
Maynard Road and Cary Parkway in Wake County. Your project has been forwarded to Mr. Danny Smith
[phone] of DWQ Raleigh Regional Office for review. This review will likely require an on-site
inspection prior to the approval, modification or denial of your project site. If you have sent additional
information to the U.S. Army Corps of Engineers concerning this project, please be certain that our staff
have copies of this material so we can use it in our process in making a decision.
According to our preliminary, in-house review since you propose to disturb greater than 150 linear feet
of streams, it is likely that compensatory mitigation will be required by DWQ for this project as described
in 15A NCAC 2H .0506 (b)(6). Our Regional Office staff can make this decision during their site visit. If
adequate mitigation is required but not provided, this project will likely have to be denied. If stream
mitigation is needed, the wetland Restoration Program can satisfy this requirement at $125 per linear foot of
stream. Otherwise you will have to identify a suitable mitigation site and develop an approvable mitigation
plan. Also if a mitigation plan is required, we will place this project on hold until its receipt in our Central
Office. Enclosed are materials describing compensatory mitigation requirements for this program. Please
call me at 919-733-1786 to discuss these matters if necessary. Until a mitigation plan is provided, this
application is considered to be incomplete and our processing time will not start
We recommend that you not impact any wetlands or waters on your project site until a 401 Water
Quality Certification has been issued from Raleigh, The issuance of a Corps of Engineers 404 Permit does
not mean that your project can proceed. According to the Clean Water Act, the 404 Permit is not valid
until a 401 Certification is also issued. If DWQ staff observe impacts which are not allowable, you will be
required to remove the fill and restore the site to its original condition. I can be reached at 919-733-1786 if
you have any questions about the 401 Certification process.

1.0 INTRODUCTION AND PROJECT PURPOSE
The purpose of this document is to propose a plan for compensatory mitigation
of stream impacts associated with the development of the Arbor Investments,
L.L.C. property located in Cary, North Carolina (herein afterwards referred to as
the 'Property").
The proximity of the Town of Cary to major employment, transportation,
recreation and educational facilities makes it one of the fastest growing cities in
the State of North Carolina. The Town of Cary is dependent on private
development initiatives to meet the residential, retail and recreational demands
of the growing population. The Town of Cary implements strict zoning
restrictions that control the engineering and aesthetics of this growth in a
planned and thoughtful manner. Arbor Investments, L.L.C., a private
development initiative, is proposing to meet some of the demand pressures of
the growing residential and commercial sectors by the developing the Property
with a diversity of uses, including light industrial, multi-family residential, single-
family residential and commercial uses.
The project purpose is to construct the infrastructure necessary to develop the
Property for diverse uses, including light industrial, multi-family residential,
single-family residential and commercial uses. These land uses are those
typically provided by private commercial developers to meet the needs of private
citizens and private businesses.
The intention of the stream mitigation outlined by this plan is to construct a
substitute stream channel that will compensate for the stream channels
segments that will be altered by project activities conducted under Nationwide
Permit (NWP) 26. Regional conditions imposed by the U.S. Army Corps of
Engineers, Wilmington District Regulatory Branch, dated May 15, 1997, require
applicants provide notification to the Wilmington District Engineer and receive
written approval prior to performing work that would impact more than 150 feet of
a stream. Notification will include the location of work, a description of work, a
discussion of alternatives to working in the stream and why alternatives were not
selected, and a plan to mitigate for all avoidable adverse impacts to more than
150 linear feet of the stream.
ECPS Project No. 0006-001 Page - 2
E/YYl/40A71/FJVTitL CO/VSULTiQM7S?NOgR{dTSFfG'lrfL/STS
This plan for stream mitigation is to construct 350 of new stream channel for the
500 feet of stream channel proposed to be altered as required by the federal
regional guidelines that pertain to NWP 26. Other impacts described in this
stream mitigation plan do not require mitigation but are provided for the sake of
completeness. Adverse impacts of the other impacts of the project (NWP 14
activities) are considered to be no more than minimal and that the aquatic
environment will be protected.
This plan is to provide information for evaluation of the proposed stream
mitigation by the natural resource agencies and is to also serve as a guidance
document for future detailed engineering, construction and monitoring of the
created stream segment.

2.0 NOTIFICATION REQUIREMENTS
2.1 Location of Work and Property Description
The Property is a tract approximately 120 acres in size located between the
proposed Cary Parkway and Maynard Road in the Town of Cary, Wake County,
North Carolina (see Figure 1 - Site Location Map, Arbor Investments, L.L.C.
Property).
The Property is typical of properties in the Piedmont geographical province. The
Property is moderately eroded and dissected with a significant drainage system.
Vegetation consists of mature hardwoods, except in the central portion of the
property, north of Coles Branch, and in portions of the floodplain south of Coles
Branch. Here the Property is vegetated with young pines and mixed hardwoods.
The WKIX antennae site is grassed. Overall, development of the Property will
entail relatively minor environmental impacts.
Coles Branch is a significant environmental feature of the Property. Coles
Branch traverses the Property from the east to west and consists of a narrow
perennial stream and flood plain. The Town of Cary restricts development
within floodplains and no construction or development activities (with the
exception of this proposed stream mitigation) are proposed by Arbor
Investments, L.L.C. within the Coles Branch floodplain.
The waters and wetlands of the site have been delineated and surveyed. The
waters and wetland locations have been verified by the U.S. Army Corps of
Engineers. Wetlands and waters on the Property account for an insignificant
amount of the total land area. The project avoids wetland impacts entirely.
2.2 Description of Work
The project will involve the construction of the infrastructure necessary to
develop the Property for diverse uses, including light industrial, multi-family
residential, single-family residential and commercial uses. The impacts of the
project are to 'Waters of the United States" primarily from several minor road
crossings that will access upland areas located on either side of several
intermittent tributaries of Coles Branch. Within the perimeter of the commercial
ECPS Project No. 0006-001 Page - 4
ENWRVW.NENTifL CONSI/LTi?MS.QNOR?/V1?6?TSPfCI•fL/STS
development, portions of the intermittent tributaries will be displaced for parking
lot construction.
The location of the project impacts relative to the Property are illustrated in
Figure 2. More detail of the proposed development at each location is illustrated
in Figures 3 through 10. A summary of the project impacts are indicated in
Table 1. It is anticipated that approximately 5708 square feet (0.131 acres) of
waters will be altered by the proposed project activities. As required under NWP
26 regional conditions, of the 500 feet of stream channel proposed to be altered,
350 feet of new stream channel is proposed to be constructed.

3.0 DISCUSSION OF ALTERNATIVES TO THE PROPOSAL
The selection of this Property consisted of a process involving the evaluation
and consideration of various engineering, economic and environmental factors.
The principal controlling factors considered in proposing the utilization of the
Property for the proposed project activities are as follows:
Ownership. The Property is under the ownership of Arbor Investments,
L.L.C. The Property was purchased for development purposes. The
proposed impacts are the minimal necessary for economical development of
the Property in accordance with the owner's investment-backed expectations.
Location. The Property is located within the Town of Cary adjacent to
developed tracts. The Property is proposed to be traversed by major
transportation arteries. A major thoroughfare (Cary Parkway extension) has
been proposed and is under consideration for construction that will border
the western portion of the Property. The Property itself will be traversed by
James Jackson Avenue (included as a portion of the proposed development
for the Property in this application) which will connect the proposed Cary
Parkway extension with North Maynard Road. Each of the public
thoroughfares mentioned are part of the approved thoroughfare plan for the
Town of Cary, which was approved by the Town and the NC Department of
Transportation.
Availability of Public Utilities. Water, sewer and natural gas are available at
the Property. Previous public investment was made in the installation of
these services in logical anticipation of future site development.
Since the stream impacts proposed under NWP 26 at the commercial retail
project south of James Jackson Avenue are the only stream impacts being
mitigated for in this plan, this alternatives discussion will focus on the stream
impacts surrounding this aspect of the project. The , stream impacts of the
commercial retail project consist primarily of fills for parking lot construction.
Alternative parking lot configurations at the commercial retail project have been
considered and where feasible, modifications have been made to the proposed
project design. The use of bridges for the parking lots was judged to be
impractical and economically unfeasible. The use of retaining walls to contain
ECPS Project No. 0006-001 Page - 8
.-"W0NA/E/VTAL CONSUL TAW7.VAAVPEf7WrMW=U1S7S
parking lot side-slope fills was judged to create a safety issue, in addition to
being impractical and economically unfeasible for both initial construction and
long-term maintenance. The "no-build" alternative was also considered and
rejected as it would not meet the project purpose. Additionally, the "no-build"
altemative would not be in the public interest because the location of the project
has the potential of serving a large population base with needed services (i.e.
food, pharmacy, offices, etc.).
There are no alternative sites for the commercial retail project that have the
ownership, zoning, location or the availability of public services that would meet
the project purpose and have significantly less impacts. The design of the
proposed commercial retail project minimizes water and wetland impacts to the
maximum extent possible while still meeting the project purpose. The following
section describes the measures that will be employed in providing compensatory
mitigation for the intermittent stream impacts.

4.0 PLAN TO MITIGATE FOR STREAM IMPACTS
4.1 Stream Characterization
Intermittent streams on the Property are generally characterized by shallow,
narrow, eroded channels approximately three (3) feet deep, with a base of
approximately two (2) feet and a top width of approximately four (4) feet. The
stream channels are relatively straight in plan view and have occasional riffle
and pool sequences within the stream beds. Some stream segments appeared
to be relic agricultural ditches due to their extreme linear nature and lack of any
definable riffle and pool sections. The stream banks are typically stabilized by a
growth of mixed hardwoods and pines that vary in age from shrubs and saplings
to mature trees.
4.2 Stream Mitigation Site Description
The stream mitigation site (see Figure 11, Site Map, Stream Mitigation Project) is
located within the floodplain of Coles Branch. The site is vegetated with shrub
and sapling species that include mixed hardwoods and pines. Soils are alluvial
sediment deposits from Coles Branch.
4.3 Stream Mitigation Concept
The stream mitigation concept will involve the construction of an intermittent
stream channel supplied with stormwater during rainfall events from the adjacent
commercial retail project. The constructed stream channel will roughly parallel
Coles Branch, in order to prevent the discharge of sediment into the constructed
stream during high-flow events.
The project construction sequence will minimize disturbance to vegetation as
much as possible in gaining access to the site by hand clearing or utilizing a
mower to clear the proposed stream corridor. Material from the channel
excavation will be widely distributed to allow secondary growth of the indigenous
vegetation from the existing roots and to reduce the possibility of the spoil
material eroding back into the constructed stream channel.
Rock material from offsite consisting of a mixture of rock sizes (2-18 inch) will be
used to construct the riffle and pool sequences in accordance with state
ECPS Project No. 0006-001 Page - 10
ARM
ENYA40AG/ENTifL CONSULT.QNTS.?I1®PFRIdTSPFCGfL/S73'
guidelines. The stream development will be monitored after completion for
vegetation growth and sedimentation,
4.4 Stream Mitigation Site Modifications
The proposed site modifications will begin with a sediment basin at the upper
end of the proposed stream channel construction. The sediment basin is to be
installed as part of the site clearing operations for the proposed retail center.
The sediment basin will be designed to remain after construction of the
proposed retail center is completed and its discharge will form the upper-most
point of the proposed stream mitigation. Stormwater from the buildings and
parking areas of the westernmost portion of.the shopping center will provide
intermittent flow to the constructed stream. The drainage area is calculated to
be 3.2 acres. Runoff calculations have been prepared by Withers & Ravenel
and are included in the Appendix of this report.
The proposed site modifications (see Figures 12 and 13) for the constructed
stream channel will include a construction sequence that will minimize impacts to
existing vegetation and unnecessary disruption to soils. This will be
accomplished by either hand clearing existing vegetation or utilizing a mower, as
site conditions allow, in the mitigation area. Clearing of the vegetation will
involve cutting the existing plants to the roots but leaving the roots intact.
Cuttings will be piled in portions of the cleared area away from the proposed
stream route.
Once the stream channel corridor is cleared of vegetation, the site will be
accessed with rubber-tired equipment, such as a backhoe or a bobcat. The
equipment will excavate the channel in accordance with the sizes indicated in
Figure 13. Spoil from the excavation will be placed in alternate piles on either
side of the channel excavation and leveled as much as possible with the
equipment bucket. Every attempt will be made to spread the spoil from the
excavation thin enough so the indigenous vegetation will redevelop.
Following the excavation, the pool and riffle breaks will be installed in
accordance with the specifications outlined in Figure 13. The material utilized to
form the pool and riffle steps will be brought into the site utilizing rubber-tired
equipment and positioned by hand.

5.0 MITIGATION REMEDIATION AND SECURITY
5.1 Mitigation Monitoring
The constructed stream segment will be monitored upon completion for a period
of three years for vegetation establishment (bank stabilization) and
sedimentation levels. Regular inspections of the site will be conducted by a
consultant hired by Arbor Investments, L.L.C. on a yearly basis and a brief letter
will be provided to the U.S. Army Corps of Engineers regarding the inspection
observations. The inspection letter will provide information regarding the height
of the previously-disturbed vegetation and will provide information regarding the
level of sedimentation or down-cutting taking place in the constructed stream.
Any other information deemed important by the consultant will be provided in this
letter also.
5.2 Mitigation Area Remediation
Mitigation monitoring letters described in Section 5.1 will include suggested
remedial measures if the inspection indicates such measures may be required.
If it is noted the stream mitigation is performing unsatisfactorily, the consultant
and the Arbor Investments, L.L.C. managers will provide a best professional
judgment regarding the reason(s) for the unsatisfactory performance. The
consultant and the Arbor Investments, L.L.C. managers may also suggest
remedial measures to correct the deficiency in the mitigation area. Remedial
measures will be evaluated in consideration of the performance standards
outlined in Section 5.1.
Where the mitigation monitoring reports identify no deficiencies in the mitigation
area performance and include no recommendations for remedial measures, no
response from the principal state and federal wetland resource authorities within
30 days will be considered acceptance of the site progress for the pertinent
monitoring interval. In the event the mitigation monitoring report includes a
recommendation for remedial measures, the principal state and federal wetland
resource authorities will provide concurrence or an independent
recommendation within 30 days of submittal of the mitigation monitoring report.

5.3 Mitigation Security
The mitigation site is currently owned by Arbor Investments, L.L.C.. Should the
surrounding properties be sold in the future, Arbor Investments, L.L.C. will
retain a maintenance easement on the site for the duration of the mitigation
monitoring period. Arbor Investments, L.L.C. will convey, as part of the property
parcel, the stream mitigation and the buffer zone area. At the end of the
monitoring period maintenance of this stream mitigation will convey to the
buyers.

RE: James Jackson Shopping Center
Wetlands Mitigation
Dear Randy:
Hamilton E Withers, P.
Samuel F. Ravene4 P.
James E CanfeI4 P.
LoJtee G. Smith, P.
Jimmy E Bass, RL
3lichael E Dickerson, RL
This letter is in reference to the design of the channel mitigation to compensate for wetlands
impacts at the reference site.
Our design criteria was based on Nelson Paul's memo to Pony, dated 5/22/97.
Summarizing our design parameters, we computed a 2 year peak discharge of 15 CFS for a
3.2 acre drainage area assuming a runoff curve number cf 95. Our worm distribution was the
SCS type 2 rainfall distribution with an antecedent moismre condition 2.
We designed the channel to just overflow during the lino 1 ear storm as opposed to the typical
design which would put freeboard to prevent overflowing during the specified design storm.
The intent here is to have "out of bank" flow and to crew:` a low velocity meandering channel
which will improve water quality and mitigate the loss of wetlands. I have assumed a design
depth of 1' for three different channel slopes allowing for bottom with to vary with the slope.
You will want to do a preliminary layout to df--ermine what slope to excavate the channel on.
The following will hold true for a depth of 1' and a m=:rn s "n- cr .030 and 2.5:1 side
slop:
DEPTH SLOPE(%) BOTTOM WIDTH (FEET)
1.0 0.5 3.1
1.0 1.0 1.8
1.0 2.0 0.8
The channel should be lined with "Enkamat" 7020 to allow stabilization with vegetation. The
vegetation should be a wetlands variety to be selected by Nelson Paul. If the depth I am
showing does not work out, please notify me and I will generate some additional channel
sections for other depths or slopes.
Sincerely,
aPE

State guidelines it dlcate the stream channel cross-section should be designed to carry no more than the 2-year,
24 !tics storm Pool to riffle sequence should be spaced at 5 to 7 times the channel width and pools are
generaify two times deeper than the riTa area. In order to prerent the increased Lost of streambank restoration
(and potential failure of the mitigation), prior to constructing the stream mitigation, the area should be mowed or
Weved by han& h may be tint the caashucted stream efunnel could be plowed Into the substrate or either -
eked w!tfi a Kbber-tired backhoe. We may need to discm where and how the fill Is to be placed if the latte'

1005 High House Road
Cary, NC 27513
Dear Mr. Smith:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
material in 0.033 acres of waters (360 linear feet) for the purpose of constructing a road crossing at James
Jackson Road, as you described in your application dated 7 April 1997 (revised plan received 18 June 1997).
After reviewing your application, we have decided that this fill is covered by General Water Quality Certification
Number 3103. This certification allows you to use Nationwide Permit Number 14 when it is issued by the
Corps of Engineers.
This approval is only valid for the purpose and design that you described in your application except as
modified below. If you change your project, you must notify us and you may be required to send us a new
application. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation
may be required as described in 15A NCAC 211.0506 (h) (6) and (7). For this approval to be valid, you must
follow the conditions listed in the attached certification and any additional conditions listed below. The culverts
under the roads shall be countersunk to allow aquatic life movement. Applicant is reminded that a stormwater
management plan will eventually be needed for the adjoining parcels if the area is developed for commercial or
industrial use. In addition, you should get any other federal, state or local permits before you go ahead with your
project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and
Water Supply Watershed regulations. This approval will expire when the accompanying 404 or CAMA permit
expires unless otherwise specified in the General Certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition
which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative
Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions are final and
binding unless you ask for a hearing.

1.0 INTRODUCTION AND PROJECT PURPOSE
' The purpose of this document is to propose a plan for compensatory mitigation
of stream impacts associated with the development of the Arbor Investments,
L.L.C. property located in Cary, North Carolina (herein afterwards referred to as
' the "Property").
The proximity of the Town of Cary to major employment, transportation,
recreation and educational facilities makes it one of the fastest growing cities in
the State of North Carolina. The Town of Cary is dependent on private
' development initiatives to meet the residential, retail and recreational demands
of the growing population. The Town of Cary implements strict zoning
restrictions that control the engineering and aesthetics of this growth in a
' planned and thoughtful manner. Arbor Investments, L.L.C., a private
development initiative, is proposing to meet some of the demand pressures of
the growing residential and commercial sectors by the developing the Property
with a diversity of uses, including light industrial, multi-family residential, single-
family residential and commercial uses.
' The project purpose is to construct the infrastructure necessary to develop the
Property for diverse uses, including light industrial, multi-family residential,
single-family residential and commercial uses. These land uses are those
' typically provided by private commercial developers to meet the needs of private
citizens and private businesses.
' The intention of the stream mitigation outlined by this plan is to construct a
substitute stream channel that will compensate for the stream channels
segments that will be altered by project activities conducted under Nationwide
' Permit (NWP) 26. Regional conditions imposed by the U.S. Army Corps of
Engineers, Wilmington District Regulatory Branch, dated May 15, 1997, require
applicants provide notification to the Wilmington District Engineer and receive
' written approval prior to performing work that would impact more than 150 feet of
a stream. Notification will include the location of work, a description of work, a
discussion of alternatives to working in the stream and why alternatives were not
' selected, and a plan to mitigate for all avoidable adverse impacts to more than
150 linear feet of the stream.

ECPS Project No. 0006-001 Page - 2

' ENNHOM{/E-NT.4L CONSULTi4/V7S,Q/VOf?'/7.t//TSPFLYdL/STS

This plan for stream mitigation is to construct 350 of new stream channel for the
500 feet of stream channel proposed to be altered as required by the federal
regional guidelines that pertain to NWP 26. Other impacts described in this
stream mitigation plan do not require mitigation but are provided for the sake of
completeness. Adverse impacts of the other impacts of the project (NWP 14
activities) are considered to be no more than minimal and that the aquatic
environment will be protected.
This plan is to provide information for evaluation of the proposed stream
mitigation by the natural resource agencies and is to also serve as a guidance
document for future detailed engineering, construction and monitoring of the
created stream segment.

2.1 Location of Work and Property Description
The Property is a tract approximately 120 acres in size located between the
proposed Cary Parkway and Maynard Road in the Town of Cary, Wake County,
North Carolina (see Figure 1 - Site Location Map, Arbor Investments, L.L.C.
Property).
The Property is typical of properties in the Piedmont geographical province. The
Property is moderately eroded and dissected with a significant drainage system.
Vegetation consists of mature hardwoods, except in the central portion of the
property, north of Coles Branch, and in portions of the floodplain south of Coles
Branch. Here the Property is vegetated with young pines and mixed hardwoods.
The WKIX antennae site is grassed. Overall, development of the Property will
entail relatively minor environmental impacts.
Coles Branch is a significant environmental feature of the Property. Coles
Branch traverses the Property from the east to west and consists of a narrow
perennial stream and flood plain. The Town of Cary restricts development
within floodplains and no construction or development activities (with the
exception of this proposed stream mitigation) are proposed by Arbor
Investments, L.L.C. within the Coles Branch floodplain.
The waters and wetlands of the site have been delineated and surveyed. The
waters and wetland locations have been verified by the U.S. Army Corps of
Engineers. Wetlands and waters on the Property account for an insignificant
amount of the total land area. The project avoids wetland impacts entirely.
2.2 Description of Work
t The project will involve the construction of the infrastructure necessary to
develop the Property for diverse uses, including light industrial, multi-family
residential, single-family residential and commercial uses. The impacts of the
' project are to "Waters of the United States" primarily from several minor road
crossings that will access upland areas located on either side of several
intermittent tributaries of Coles Branch. Within the perimeter of the commercial

ECPS Project No. 0006-001 Page - 4

' E7"%9aWe.4VTAL COWS!/LTitNTSR LPA'Ll4 rSFZCIAL/STS
development, portions of the intermittent tributaries will be displaced for parking
' lot construction.
The location of the project impacts relative to the Property are illustrated in
' Figure 2. More detail of the proposed development at each location is illustrated
in Figures 3 through 10. A summary of the project impacts are indicated in
Table 1. It is anticipated that approximately 5708 square feet (0.131 acres) of
waters will be altered by the proposed project activities. As required under NWP
26 regional conditions, of the 500 feet of stream channel proposed to be altered,
350 feet of new stream channel is proposed to be constructed.

3.0 DISCUSSION OF ALTERNATIVES TO THE PROPOSAL

The selection of this Property consisted of a process involving the evaluation
and consideration of various engineering, economic and environmental factors.
The principal controlling factors considered in proposing the utilization of the
Property for the proposed project activities are as follows:
Ownership. The Property is under the ownership of Arbor Investments,
L.L.C. The Property was purchased for development purposes. The
proposed impacts are the minimal necessary for economical development of
the Property in accordance with the owner's investment-backed expectations.
Location. The Property is located within the Town of Cary adjacent to
developed tracts. The Property is proposed to be traversed by major
transportation arteries. A major thoroughfare (Cary Parkway extension) has
been proposed and is under consideration for construction that will border
the western portion of the Property. The Property itself will be traversed by
James Jackson Avenue (included as a portion of the proposed development
for the Property in this application) which will connect the proposed Cary
Parkway extension with North Maynard Road. Each of the public
thoroughfares mentioned are part of the approved thoroughfare plan for the
Town of Cary, which was approved by the Town and the NC Department of
Transportation.
Availability of Public Utilities. Water, sewer and natural gas are available at
the Property. Previous public investment was made in the installation of
these services in logical anticipation of future site development.
Since the stream impacts proposed under NWP 26 at the commercial retail
project south of James Jackson Avenue are the only stream impacts being
mitigated for in this plan, this alternatives discussion will focus on the stream
impacts surrounding this aspect of the project. The stream impacts of the
commercial retail project consist primarily of fills for parking lot construction.

Alternative parking lot configurations at the commercial retail project have been
considered and where feasible, modifications have been made to the proposed
project design. The use of bridges for the parking lots was judged to be
impractical and economically unfeasible. The use of retaining walls to contain

r
G

parking lot side-slope fills was judged to create a safety issue, in addition to
being impractical and economically unfeasible for both initial construction and
long-term maintenance. The "no-build" alternative was also considered and
rejected as it would not meet the project purpose. Additionally, the "no-build"
alternative would not be in the public interest because the location of the project
has the potential of serving a large population base with needed services (i.e.
food, pharmacy, offices, etc.).
There are no alternative sites for the commercial retail project that have the
ownership, zoning, location or the availability of public services that would meet
the project purpose and have significantly less impacts. The design of the
proposed commercial retail project minimizes water and wetland impacts to the
maximum extent possible while still meeting the project purpose. The following
section describes the measures that will be employed in providing compensatory
mitigation for the intermittent stream impacts.

ENYA70NA/ENTgL CO/YS!/LTiQ/V7SsfNOPFR/dTSiA14Y4L/SlS
4.0 PLAN TO MITIGATE FOR STREAM IMPACTS

4.1 Stream Characterization
Intermittent streams on the Property are generally characterized by shallow,
narrow, eroded channels approximately three (3) feet deep, with a base of
approximately two (2) feet and a top width of approximately four (4) feet. The
stream channels are relatively straight in plan view and have occasional riffle
and pool sequences within the stream beds. Some stream segments appeared
to be relic agricultural ditches due to their extreme linear nature and lack of any
definable riffle and pool sections. The stream banks are typically stabilized by a
growth of mixed hardwoods and pines that vary in age from shrubs and saplings
to mature trees.
4.2 Stream Mitigation Site Description
The stream mitigation site (see Figure 11, Site Map, Stream Mitigation Project) is
located within the floodplain of Coles Branch. The site is vegetated with shrub
and sapling species that include mixed hardwoods and pines. Soils are alluvial
sediment deposits from Coles Branch.
4.3 Stream Mitigation Concept

[i

The stream mitigation concept will involve the construction of an intermittent
stream channel supplied with stormwater during rainfall events from the adjacent
commercial retail project. The constructed stream channel will roughly parallel
Coles Branch, in order to prevent the discharge of sediment into the constructed
stream during high-flow events.
The project construction sequence will minimize disturbance to vegetation as
much as possible in gaining access to the site by hand clearing or utilizing a
mower to clear the proposed stream corridor. Material from the channel
excavation will be widely distributed to allow secondary growth of the indigenous
vegetation from the existing roots and to reduce the possibility of the spoil
material eroding back into the constructed stream channel.
Rock material from offsite consisting of a mixture of rock sizes (2-18 inch) will be
used to construct the riffle and pool sequences in accordance with state

11

n

r

ENY/g0/VMENT.4C CONSULTA/YTSRNOPF/4A//TSh2GlAL/S7S
guidelines. The stream development will be monitored after completion for
vegetation growth and sedimentation.
4.4 Stream Mitigation Site Modifications
The proposed site modifications will begin with a sediment basin at the upper
end of the proposed stream channel construction. The sediment basin is to be
installed as part of the site clearing operations for the proposed retail center.
The sediment basin will be designed to remain after construction of the
proposed retail center is completed and its discharge will form the upper-most
point of the proposed stream mitigation. Stormwater from the buildings and
parking areas of the westernmost portion of the shopping center will provide
intermittent flow to the constructed stream. The drainage area is calculated to
be 3.2 acres. Runoff calculations have been prepared by Withers & Ravenel
and are included in the Appendix of this report.
The proposed site modifications (see Figures 12 and 13) for the constructed
stream channel will include a construction sequence that will minimize impacts to
existing vegetation and unnecessary disruption to soils. This will be
accomplished by either hand clearing existing vegetation or utilizing a mower, as
site conditions allow, in the mitigation area. Clearing of the vegetation will
involve cutting the existing plants to the roots but leaving the roots intact.
Cuttings will be piled in portions of the cleared area away from the proposed
stream route.
Once the stream channel corridor is cleared of vegetation, the site will be
accessed with rubber-tired equipment, such as a backhoe or a bobcat. The
equipment will excavate the channel in accordance with the sizes indicated in
Figure 13. Spoil from the excavation will be placed in alternate piles on either
side of the channel excavation and leveled as much as possible with the
equipment bucket. Every attempt will be made to spread the spoil from the
excavation thin enough so the indigenous vegetation will redevelop.
Following the excavation, the pool and riffle breaks will be installed in
accordance with the specifications outlined in Figure 13. The material utilized to
form the pool and riffle steps will be brought into the site utilizing rubber-tired
equipment and positioned by hand.

5.0 MITIGATION REMEDIATION AND SECURITY
u

5.1 Mitigation Monitoring
The constructed stream segment will be monitored upon completion for a period
of three years for vegetation establishment (bank stabilization) and
sedimentation levels. Regular inspections of the site will be conducted by a
consultant hired by Arbor Investments, L.L.C. on a yearly basis and a brief letter
will be provided to the U.S. Army Corps of Engineers regarding the inspection
observations. The inspection letter will provide information regarding the height
of the previously-disturbed vegetation and will provide information regarding the
level of sedimentation or down-cutting taking place in the constructed stream.
Any other information deemed important by the consultant will be provided in this
letter also.
5.2 Mitigation Area Remediation
Mitigation monitoring letters described in Section 5.1 will include suggested
remedial measures if the inspection indicates such measures may be required.
If it is noted the stream mitigation is performing unsatisfactorily, the consultant
and the Arbor Investments, L.L.C. managers will provide a best professional
judgment regarding the reason(s) for the unsatisfactory performance. The
consultant and the Arbor Investments, L.L.C. managers may also suggest
remedial measures to correct the deficiency in the mitigation area. Remedial
measures will be evaluated in consideration of the performance standards
outlined in Section 5.1.
Where the mitigation monitoring reports identify no deficiencies in the mitigation
area performance and include no recommendations for remedial measures, no
response from the principal state and federal wetland resource authorities within
30 days will be considered acceptance of the site progress for the pertinent
monitoring interval. In the event the mitigation monitoring report includes a
recommendation for remedial measures, the principal state and federal wetland
resource authorities will provide concurrence or an independent
recommendation within 30 days of submittal of the mitigation monitoring report.

5.3 Mitigation Security
The mitigation site is currently owned by Arbor Investments, L.L.C.. Should the
surrounding properties be sold in the future, Arbor Investments, L.L.C. will
retain a maintenance easement on the site for the duration of the mitigation
monitoring period. Arbor Investments, L.L.C. will convey, as part of the property
parcel, the stream mitigation and the buffer zone area. At the end of the
monitoring period maintenance of this stream mitigation will convey to the
buyers.

RE: James Jackson Shopping Center
Wetlands Mitigation
' Dear Randy:
This letter is in reference to the design of the channel mitigation to compensate for wetlands
' impacts at the reference site.
Our design criteria was based on Nelson Paul's memo to Tony, dated 5/22/97.
Summarizing our design parameters, we computed a 2 year peak discharge of 15 CFS for a
3.2 acre drainage area assuming a runoff curve number of 95. Our storm distribution was the
SCS type 2 rainfall distribution with an antecedent moisture condition 2.
We designed the channel to just overflow during the two year storm as opposed to the typical
design which would put freeboard to prevent overflowing during the specified design storm.
The intent here is to have "out of bank" flow and to create a low velocity meandering channel
' which will improve water quality and mitigate the loss of wetlands. I have assumed a design
depth of 1' for three different channel slopes allowing the bottom width to vary with the slope.
You will want to do a preliminary layout to determine what slope to excavate the channel on.
' The following will hold true for a depth of 1' and a mannings "n" of .030 and 2.5:1 side
slopes:
DEPTH SLOPE(%) BOTTOM WIDTH (FEET)
' 1.0 0.5 3.1
1.0 1.0 1.8
1.0 2.0 0.8

The channel should be lined with "Enkamat" 7020 to allow stabilization with vegetation. The
vegetation should be a wetlands variety to be selected by Nelson Paul. If the depth I am
showing does not work out, please notify me and I will generate some additional channel
sections for other depths or slopes.
Sincerely,
4am-u--el . Ravenel, PE

Tony, I have checked with the COE regarding the guidance on stream mitigation. Ken Jolly indicated the state
Quidelines would be One for now in their consideration of the stream mitigation plan.
State guidelines Indicate the stream channel cross-section should be designed to carry no more than the 2-year,
24 hour storm. Pool to riffle sequence should be spaced at 5 to 7 times the channel width and pools are
generally two times deeper than the riffle area. In order to prevent the increased cost of streambank restoration
(and potential failure of the mitigation), prior to constructing the stream mitigation, the area should be mowed or
cleared by hand. It may be that the constructed stream channel could be plowed into the substrate or either
excavated with a rubber-tired backhoe. We may need to discuss where and how the f111 is to be placed if the latter
alternative is utilized. State guidance indicates the use of tiprap should be minimized.

Mr. Tim Smith
c/o Mr. Randy Smith
Arbor Investments, L.L.C.
1005 High House Road
Cary, North Carolina 27513
Dear Mr. Smith:
Please reference the April 8, 1997 permit application,
submitted on your behalf by Mr. Nelson G. Paul of Environmental
Consultants and Permit Specialists, for Department of the Army
(DA) approval to discharge fill material over 0.03 acre of
jurisdictional waters (bank-to-bank tributaries) of the United
States for the proposed construction of the James Jackson Avenue
extension, from existing James Jackson Avenue west to the
proposed Cary Parkway connector, associated with your future
commercial development on the adjacent property. This proposed
development, containing 192.3 acres, is located adjacent to and
above the headwaters of Coles Branch, in Cary, Wake County, North
Carolina.
The application you have submitted does not include the
anticipated impacts associated with the proposed construction of
the adjacent, related commercial development. We would
anticipate that adverse environmental impacts will occur as a
result of additional fills within jurisdictional waters and/or
wetlands associated with this project. Our regulations, (Title
33 of the Code of Federal Regulations, Part 325), outline
processing procedures for a Department of the Army (DA) permit.
We are required to look at "all activities which the applicant
plans to undertake which are reasonably related to the same
project and for which a DA permit would be required... District
Engineers should reject, as incomplete, any permit application
11

' which fails to comply with this requirement." In addition,
pursuant to December 13, 1996 Federal Register, Final Notice of
' Issuance, Reissuance, and Modification of Nationwide Permits (61
FR 65874), General Condition 13(b)(3), notification to the
District Engineer must include "any other NWP(s), regional
' general permit(s) or individual permit(s) used or intended to be
used to authorize any part of the proposed project or any related
activity."
1 Mr. Eric Alsmeyer of my regulatory staff verbally explained
our concerns to Mr. Paul during their telephone conversation of
' May 8, 1997. He outlined the fact that we have determined that
the commercial development is reasonably related to the proposed
road. In addition, based upon all information available to us at
' this time, we would have to consider the entire commercial
development to be a single and complete project, the segmentation
' of which would preclude reasonable and feasible alternatives for
minimization and avoidance of wetland impacts for the portions
requiring an individual permit. Based upon our conclusions, you
' are notified that the application you have submitted is not
complete and therefore cannot be processed at this time. You are
advised to re-evaluate the manner in which you have applied for
' our approval and to resubmit the application with all required
information. We will commence the processing of your application
upon receipt of all complete and accurate information regarding
' the additional jurisdictional activities associated with the
project.
' Please note that the following information will likely apply
to the proposed project, particularly if your complete
' application involves an individual DA permit. On November 15,
1989, the Department of the Army and the U.S. Environmental
Protection Agency signed a memorandum of agreement (MOA)
' establishing procedures to determine the type and level of
mitigation necessary to comply with the Clean Water Act, Section
404(b)(1) Guidelines. This MOA, which became effective on
' February 6, 1990, provides for (1) avoiding impacts to waters and
wetlands through the selection of the least damaging, practicable
alternative; (2) taking appropriate and practicable steps to
' minimize impacts to waters and wetlands; and (3) compensating for
any remaining unavoidable impacts to the maximum extent
2

' practicable and appropriate. To enable the Regulatory Branch to
process a permit application in full compliance with this MOA,
' the following additional information should be provided with any
application:
a. Permits are available only for work dependent upon being
located within an aquatic site and being the least
environmentally damaging, practicable alternative. Information
' (alternatives analysis) regarding any other practicable
alternatives, including upland alternatives, to the work for
which you may apply must be provided, as well as justification
' that your selected plan is the least damaging to waters and/or
wetland areas.
' b. It is necessary for you to have taken all appropriate and
practicable steps to minimize wetland losses. Please indicate
' all that you have done, especially regarding development and
modification of plans and proposed construction techniques, to
minimize adverse impacts.
C. The MOA then states that appropriate and practicable
mitigation will be required for all unavoidable adverse impacts
' remaining after practicable minimization has been employed.
Please outline your plan to mitigate for the projected,
unavoidable losses of waters and/or wetlands, or provide
' information as to the absence of any such appropriate and
practicable measures.

Dear S irs:
A!,
ID F= F1
April 25, 1997
DWQ #970326
Wake County
' On 4 April 1997, you applied to the N.C. Division of Water Quality (DWQ) for a 401 Water Quality
Certification to impact 360 linear feet of waters for your project (James Jackson Ave.) located at North
Maynard Road and Cary Parkway in Wake County. Your project has been forwarded to Mr. Danny Smith
t [phone] of DWQ Raleigh Regional Office for review. This review will likely require an on-site
inspection prior to the approval, modification or denial of your project site. If you have sent additional
information to the U.S. Army Corps of Engineers concerning this project, please be certain that our staff
have copies of this material so we can use it in our process in making a decision.

According to our preliminary, in-house review since you propose to disturb greater than 150 linear feet
of streams, it is likely that compensatory mitigation will be required by DWQ for this project as described
in 15A NCAC 2H.0506 (b)(6). Our Regional Office staff can make this decision during their site visit. If
adequate mitigation is required but not provided, this project will likely have to be denied. If stream
mitigation is needed, the wetland Restoration Program can satisfy this requirement at $125 per linear foot of
stream. Otherwise you will have to identify a suitable mitigation site and develop an approvable mitigation
plan. Also if a mitigation plan is required, we will place this project on hold until its receipt in our Central
Office. Enclosed are materials describing compensatory mitigation requirements for this program. Please
call me at 919-733-1786 to discuss these matters if necessary. Until a mitigation plan is provided, this
application is considered to be incomplete and our processing time will not start.
We recommend that you not impact any wetlands or waters on your project site until a 401 Water
Quality Certification has been issued from Raleigh, The issuance of a Corps of Engineers 404 Permit does
not mean that your project can proceed. According to the Clean Water Act, the 404 Permit is not valid
until a 401 Certification is also issued. If DWQ staff observe impacts which are not allowable, you will be
required to remove the fill and restore the site to its original condition. I can be reached at 919-733-1786 if
you have any questions about the 401 Certification process.

May 13, 1997
On 9 May 1997 the Division of Water Quality (DWQ) was notified by receipt of a copy
of the 8 May 1997 letter from the U.S. Army Corps of Engineers regarding your plan to fill
waters for the purpose of constructing James Jackson Road in Wake County. Approval
from DWQ is required to disturb these wetlands. According to the Corps letter, your
application is incomplete since it did not address the impact of the adjacent, related
commercial development. Until you submit additional information and the Corps agrees
that the project is complete, we will place this project on hold. As you are aware, Mr. Eric
Fleek of our Raleigh Regional Office visited the site on 7 May 1997 and determined that
stream mitigation would not be needed for these road crossings. The Central Office agrees
with this determination.
Please call me at 919-733-1786 if you have any questions or would require copies of
our rules or procedural materials.

Dear Mr. Smith:

?o????Tgl yJ99J

Please reference the April 8, 1997 permit application,
submitted on your behalf by Mr. Nelson G. Paul of Environmental
Consultants and Permit Specialists, for Department of the Army
(DA) approval to discharge fill material over 0.03 acre of
jurisdictional waters (bank-to-bank tributaries) of the United
States for the proposed construction of the James Jackson Avenue
extension, from existing James Jackson Avenue west to the
proposed Cary Parkway connector, associated with your future
commercial development on the adjacent property. This proposed
development, containing 192.3 acres, is located adjacent to and
above the headwaters of Coles Branch, in Cary, Wake County, North
Carolina.
The application you have submitted does not include the
anticipated impacts associated with the proposed construction of
the adjacent, related commercial development. We would
anticipate that adverse environmental impacts will occur as a
result of additional fills within jurisdictional waters and/or
wetlands associated with this project. Our regulations, (Title
33 of the Code of Federal Regulations, Part 325), outline
processing procedures for a Department of the Army (DA) permit.
We are required to look at "all activities which the applicant
plans to undertake which are reasonably related to the same
project and for which a DA permit would be required... District
Engineers should reject, as incomplete, any permit application
which fails to comply with this requirement." In addition,
pursuant to December 13, 1996 Federal Register, Final Notice of
Issuance, Reissuance, and Modification of Nationwide Permits (61
FR 65874), General Condition 13(b)(3), notification to the
District Engineer must include "any other NWP(s), regional
general permit(s) or individual permit(s) used or intended to be
used to authorize any part of the proposed project or any related
activity."
Mr. Eric Alsmeyer of my regulatory staff verbally explained
our concerns to Mr. Paul during their telephone conversation of
May 8, 1997. He outlined the fact that we have determined that
the commercial development is reasonably related to the proposed
road. In addition, based upon all information available to us at
this time, we would have to consider the entire commercial
development to be a single and complete project, the segmentation
of which would preclude reasonable and feasible alternatives for
minimization and avoidance of wetland impacts for the portions
requiring an individual permit. Based upon our conclusions, you
are notified that the application you have submitted is not
complete and therefore cannot be processed at this time. You are
advised to re-evaluate the manner in which you have applied for
our approval and to resubmit the application with all required
information. We will commence the processing of your application
upon receipt of all complete and accurate information regarding
the additional jurisdictional activities associated with the
project.
Please note that the following information will likely apply
to the proposed project, particularly if your complete
application involves an individual DA permit. On November 15,
1989, the Department of the Army and the U.S. Environmental
Protection Agency signed a memorandum of agreement (MOA)
establishing procedures to determine the type and level of
mitigation necessary to comply with the Clean Water Act, Section
404(b)(1) Guidelines. This MOA, which became effective on
February 6, 1990, provides for (1) avoiding impacts to waters and
wetlands through the selection of the least damaging, practicable
alternative; (2) taking appropriate and practicable steps to
minimize impacts to waters and wetlands; and (3) compensating for
any remaining unavoidable impacts to the maximum extent
2
practicable and appropriate. To enable the Regulatory Branch to
process a permit application in full compliance with this MOA,
the following additional information should be provided with any
application:
a. Permits are available only for work dependent upon being
located within an aquatic site and being the least
environmentally damaging, practicable alternative. Information
(alternatives analysis) regarding any other practicable
alternatives, including upland alternatives, to the work for
which you may apply must be provided, as well as justification
that your selected plan is the least damaging to waters and/or
wetland areas.
b. It is necessary for you to have taken all appropriate and
practicable steps to minimize wetland losses. Please indicate
all that you have done, especially regarding development and
modification of plans and proposed construction techniques, to
minimize adverse impacts.
C. The MOA then states that appropriate and practicable
mitigation will be required for all unavoidable adverse impacts
remaining after practicable minimization has been employed.
Please outline your plan to mitigate for the projected,
unavoidable losses of waters and/or wetlands, or provide
information as to the absence of any such appropriate and
practicable measures.
Any questions or comments, as well as your complete
Department of the Army permit package, should be addressed to
Mr. Alsmeyer at telephone [phone], extension 23.

S. Kenneth Jolly

Project. This Project is not anticipated to impact wetlands or special aquatic sites, however, the
application is being submitted as if the "Notification" general condition applies. Please review
and call me at [phone] or on my voice mail/pager [phone], if you have any

Dear Sirs:

April 25, 1997
DWQ #970326
Wake County
On 4 April 1997, you applied to the N.C. Division of Water Quality (DWQ) for a 401 Water Quality
Certification to impact 360 linear feet of waters for your project (James Jackson Ave.) located at North
Maynard Road and Cary Parkway in Wake County. Your project has been forwarded to Mr. Danny Smith
[phone] of DWQ Raleigh Regional Office for review. This review will likely require an on-site
inspection prior to the approval, modification or denial of your project site. If you have sent additional
information to the U.S. Army Corps of Engineers concerning this project, please be certain that our staff
have copies of this material so we can use it in our process in making a decision.
According to our preliminary, in-house review since you propose to disturb greater than 150 linear feet
of streams, it is likely that compensatory mitigation will be required by DWQ for this project as described
in 15A NCAC 2H .0506 (b)(6). Our Regional Office staff can make this decision during their site visit. If
adequate mitigation is required but not provided, this project will likely have to be denied. If stream
mitigation is needed, the wetland Restoration Program can satisfy this requirement at $125 per linear foot of
stream. Otherwise you will have to identify a suitable mitigation site and develop an approvable mitigation
plan. Also if a mitigation plan is required, we will place this project on hold until its receipt in our Central
Office. Enclosed are materials describing compensatory mitigation requirements for this program. Please
call me at 919-733-1786 to discuss these matters if necessary. Until a mitigation plan is provided, this
application is considered to be incomplete and our processing time will not start.
We recommend that you not impact any wetlands or waters on your project site until a 401 Water
Quality Certification has been issued from Raleigh, The issuance of a Corps of Engineers 404 Permit does
not mean that your project can proceed. According to the Clean Water Act, the 404 Permit is not valid
until a 401 Certification is also issued. If DWQ staff observe impacts which are not allowable, you will be
required to remove the fill and restore the site to its original condition. I can be reached at 919-733-1786 if
you have any questions about the 401 Certification process.

5. The Project (see below) is located north of Coles Branch, east of the proposed Cary Parkway
and west of the Town of Cary municipal offices. Access to the site is obtained from the end of the
existing James Jackson Avenue, which connects to North Maynard Road. See attached site location
map.
11. The projected impacts of the Project will only involve "Waters or the United States" (herein
afterwards referred to as "Waters") in the upper limits of two unnamed streams. No wetlands are
anticipated to be impacted by the proposed project. The impacts to Waters will be as follows:
CROSSING CROSSING AREA
DISTANCE WIDTH IMPACTED
AREA FEET FEET SQUARE FEET
1 4 175 700
2 4 185 740
TOTALS 8 360 1440
ACRES 0.033
13. The purpose of the proposed Project ("Project" refers to the Waters crossings described above)
is to connect North Maynard Road with the proposed Cary Parkway extension. James Jackson Road,
the Cary Parkway extension and North Maynard Road are public thoroughfares that are on the approved
thoroughfare plan of the Town of Cary and the NC Department of Transportation. The construction of
James Jackson Avenue, in conjunction with other approved public thoroughfares of the Town of Cary
and the NC Department of Transportation, has utility independent of any other non-transportation related
development project and is able to function or meet its public transportation purpose independent of any
other non-transportation related development activities. The waters impacted are the minimal necessary
to construct the proposed Project.
It is the understanding of Arbor Investments, L.L.C. that the construction of James Jackson Avenue will
in no way prejudice the decision on an individual permit, should an individual permit be required for the
development of any remaining properties held by Arbor Investments, L.L.C. Future applications for
individual permits, if any, will include an analysis of the impacts of the entire project, including related
activities authorized under this NWP.
14. No wetlands are to be impacted by the proposed Project.
