Dear Ms. Karoly,

We are working with the Town of Wake Forest on the development of a greenway along Smith
Creek. The proposed greenway will be constructed parallel to the Neuse River Buffer with the
exception of one location where we must cross the creek. We are requesting a buffer encroachment
subject to the Neuse River Riparian Area Protection and Maintenance Rule (15 A NCAC 2B .0233).
Under 15A NCAC 2B .0233 greenway/hiking trails are an allowable exception and by way of this
letter, we are requesting that the proposed Smith Creek Greenway be exempted from the normal
buffer rules.

Please fInd the attached plans for your use along with the completed PCN form. The proposed
project is a greenway that is known as the Smith Creek Greenway located in Wake County in the
Town of Wake Forest. The project crosses into two parcels. One parcel is owned by the Town of
Wake Forest and is PIN # 1840-62-8264. The other parcel is owned by the State of North Carolina
and is PIN # 1840-62-8697. The site is located north along Roger Road near the intersection of
Heritage Lake Road and Roger Road. The approximate project latitude is 35 57' 04.15" and
longitude 78 30'17.60". The parcels are 16.77 acres and 25.92 acres respectively. Smith Creek is the
nearest body of water and is the crossing under review. This creek is a tributary to the Neuse River.
The existing conditions of the project area are undisturbed woods. The greenway is proposed in an
existing sanitary sewer/ greenway easement. The proposed grading, greenway, and bridge have been
design to minimize the impacts in this area as much as possible. The project would impact a total of
4,800 sf of Neuse river buffer. A greenway bridge spans 50' to cross Smith Creek and has been
verifIed to be no rise to the floodplain. Please refer to attached plan for further clarifIcation of the
project and its impacts.

Thank you for your time and assistance. Should you require any additional information please
contact Warren Sugg or myself at 858-1811 or 858-1888 respectively.

Sincerely,

http://www.saw.usace.army.mil/wetlands/Permapp.htm.

The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
. USACE website at http://www.saw.usace.mmy.mil/wetIands/regtour.htm. or contact one of the field
offices listed on page 3 of this application. The website also lists the responsible project manager for
each county in North Carolina and provides additional information regarding the identification and
regulation of wetlands and waters of the U.S.

The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been determined by the USACE.
Applicants are. encouraged to visit DWQ's 401lWetlands Unit website at
http://h20.enr.state.nc.us/ncwetlands to read about current requirements for the 401 Water Quality
Certification Program and to determine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for General Certifications is not required, provided
that the applicant adheres to all conditions of the GC. Applicants lacking access to the internet should
,contact DWQ's Central Office in Raleigh at [phone].

: Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is required for projects occurring in any of North Carolina's twenty-five
counties that contain trout waters. In such cases, the applicant should contact the appropriate NCWRC
regional coordinator (listed by county on page 4 of this application) prior to submittal of the application.

Page 1 of 12

Coastal Area Management Act (CAMA) Coordination - If the project occurs in any of North Carolina's
twenty coastal counties (listed on page 4) the applicant should contact the North Carolina Division of
Coastal Management (DCM). DCM will determine whether or not the project is within a designated
Area of Environmental Concern, in which case DCM will act as the lead permitting agency. In such
cases, DCM will require a CAMA Permit and will coordinate the 404/401 Permits.

The applicant may also choose to coordinate with the United States Fish and Wildlife Service to ensure
that the proposed project will have no impact upon any endangered or threatened species or critical
habitat as regulated by the Endangered Species Act, and the State Historic Preservation Office, North
Carolina Department of Cultural Resources to ensure that the proposed project will have no impact upon
any properties listed or eligible for listing on the National Register of Historic Places. Compliance with
these regulations is required to be eligible for any Department of the Army permit. The addresses for
both agencies are listed on page 3 of this application.

USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office. Upon receipt of an application, the
USACE will determine if the application is complete as soon as possible, not to exceed 30 days. This
PCN form is designed for the convenience of the applicant to address information needs for all USACE
Nationwide, Regional or General permits, as well as information required for State authorizations,
certifications, and coordination. Fully providing the information requested on this form will result in a
complete application for any of the USACE Nationwide, Regional or General permits. To review the
minimum amount of information that must be provided for a complete PCN for each USACE
Nationwide permit, see Condition 13, 65 Fed. Reg. 12893 (March 9, 2000), available at
http://www.saw.usace.army.mil/wetlands/nwpfinaIFedReg.pdf. Processing times vary by permit and

regulatory field office for specific answers to permit processing periods.

401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated
as optional. Incomplete applications will be returned. Submit seven collated copies of all USACE
Permit materials to the Division of Water Quality, 40l/Wetlands Unit, 1650 Mail Service Center,
Raleigh, NC, 27699-1650. If written approval is required or specifically requested for a 401
Certification, then a non-refundable application fee is required. In brief, if project impacts include less
than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to
streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is
required. A check made out to the North Carolina Division of Water Quality, with the specific name of
the project or applicant identified, should be stapled to the front of the application package. For more
information, see the DWQ web site at http://h20.ehnr.state.nc.us/ncwetIands/fees.html. The fee must be
attached with the application unless the applicant is a federal agency in which case the check may be
issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check
so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules,
the application fee does not apply, and the applicant should clearly state (in a cover letter) that only
Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to
issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application
for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the
applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional
I
requested information, or denial.

VI. Proposed Impacts to Waters of the United States/Waters of the State

It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a
delineation map, whether or not impacts are proposed to these systems. Wetland and stream
evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.

Page 7 of 12

1. Provide a written description of the proposed impacts: The proposed greenway will impact
3.079 SF of riparian buffers to the south of the greenway bridge and 1,672 SF of buffers to
the north of the proposed pedestrian bridge. The impacts are due to the necessary grading to
elevate the bridge over Smith Creek. The purpose of the vedestrian bridge is to eliminate the
stream channel impacts.

2. Individually list wetland impacts below:

5. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): 0 uplands 0 stream 0 wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A

Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):

Size of watershed draining to pond:

Expected pond surface area:

VII. Impact Justification (Avoidance and Minimization)

Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
In order to eliminate impacts to the stream channel. a pedestrian bridge will be constructed to
span this critical area. The bridge will cross as close to ninety degrees as possible to further
eliminate buffer impacts. Due to the fact that Smith Creek bisects the site. there was no way to
connect the soccer complex and Rogers Road without crossing the creek. The entire buffer could
not be spanned due to the cost to construct a much longer bridge.

VIII. Mitigation

DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.

Page 9 of 12

USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.

If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h20.em.state.nc. us/ncwetlands/strmgide.html.

1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
No mitigation is proposed for this proiect.

2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the

Narrative

I

Smith Creek Greenway is a continuation of the existing greenway along Smith Creek in Wake Forest,
North Carolina. The existing and proposed greenway is North of the intersection of Heritage Lake
Road and Rogers Road as you proceed North on Rogers Road Tbis proposed greenway connects to
the existing greenway that currently goes north along the Town of Wake Forest Soccer Center then
into Heritage Subdivision. The land owners of record that the greenway will pass through are the
Town of Wake Forest and the State of North Carolina. The pin numbers are 1840-62-8264 & 1840-
62-8697 respectively. The zonings are R-8 and MF respectively and the tract acreages are 16.77 &
25.92 respectively.

I

I

The proposed connecting extension is 1200 feet long of asphalt greenway trail. The trail mix consists
of 2" of 1-2 with 6" of compacted CABC on top of a geotextile fabric. The trail will be 14 feet wide
with 10 feet of that being asphalt and 2 feet of gravel shoulder on each side. The greenway was
designed to remain inside of the existing 30 foot side sewer/ greenway easement. A small bridge has
been proposed with two abutment points and the necessary retaining walls. Please see sheet L-sc-lO
for further detail on the bridge and details on it. Three proposed culvert pass under the greenway.
All of the culverts are 15" RCP proposed to be installed at 0.50%. Rip rap apron have been
proposed at the end of each culvert to slow and dissipate the stonn water as it is released
Approximately 2400 linear feet of silt fence has been proposed to protect all of the areas that will be
disturbed The total greenway addition will disturb 1.68 ac. No other site or utilities are proposed

SOIL SURVEY

within only a narrow range of moisture content. A crust
forms after hard rains, and clods form if this soil is
worked when wet. The crust and the clods interfere with
gern~ination. As a result, a good stand of crops is hard to
obtam.
This soil is suit€d to only a limited number of crops
grown l~ally. .It is most}y in forest, and only a small
acreage IS c~ltlVa~d or In .pasture. If cultivated crops
are grown, Inten~lVe practIces that effectively control
runoff and erosIon. a~e. necessary. (qap~bility unit

eroded (CIE3).-This soil is on narrow side sloJ?es border-
ing upland ~rainage~ays.. The sur:face l::yer IS red clay
loam 3 to 6 Inches thick. Mostly, It consIsts of material
from the subsoil, but it contains some material from the
original surface layer. The subsoil is red, firm clay 30 to
40 inches thiclc.

Included with this soil in mappinO' were small areas of
a soil that has a subsoil of dark-red clay. Also included
were a few areas where the slopes are greater than 20 per-
cent.

I?filt~a~ion.is poor, and s~rface runoff is very rapid.
ThIs sOlI IS dIfficult to keep In good tilth, and it can be
worked within only a narrow range of moisture content.
A crust forms after hard rains, and clods form if this
soil is worked when wet. Because of the crust and the
clod~, a good stand of pasture and hay crops is difficult to
obtaIn.

This soil is suited to permanent hay, pasture, and for-
est, but it is chiefly in forest. It is too steep and eroded
for cultivated crops. (Capability unit VIe-2, wood-
land suitability group 5, wildlife suitability group 1)

Chewacla Series

The Chewacla series consists of nearly level, somewhat
poorly drained soils on the flood plains of most of the
s~reams in. the county. These soils have formed in allu-
VIal deposIts of fine loamy material. A seasonally high
water table is at a depth of about 1% feet.

Natural fer:ti.lity. and the content of organic matter are
low, pe:-meabIlIty IS mod:ra~ to moderately rapid, and
the avaIlable water capacIty IS medium. The shrink-swell
potential is moderate to low. These soils are frequently
flo?ded (fig. 3), .but the floodwaters remain for only a
bnef penod of tIme. Except in areas that have received
lime, the ~oil~ are stro~gly acid. Response is good if suit-
able applIcatIOns of lIme and fertilizer are made.

Colfax Series

Soils of the Colfax series, as m~pped ir: the county,
lack a fragipan, and in the futu~e WIll be aSSIgned to some
other series. The series conSIsts of. nearl~ level ~nd
gently sloping, somewhat poorly dramed SOlIs on .PIed-
mont uplands. These soils are at the heads o~ dramage-
"ays, on foot slopes, and in slight depresslOn~. They
have formed under forest, in translocatt;d materIal, a:r:d
in material that "eathered from most kInd.s of rocks In
the county. A seasonally high water ~'\,ble IS at a depth
of about 11/2 feet. '.
Natural fertility and the content of orgamc mat~r are
low. Permeability is moderately sl~w, and the ava:lab~e
"ater capacity is medium. The shrink-s~ell p~tentIal IS
moderate. Except in areas that have .recelved l:me, .these
soils are strongly acid. Respon~~ is faIrly good If SUItable
applications of lime and fertIlIzer are made. .
The Colfax soils in this county are mostly m forest
and are not important for farming. ,Vhere they have
been cleared, they are generally used for pasture or for
"aterways. The areas are mostly too small. for ~anag-
inO' as a field independent of the surroundmg. SOlIs.
Representative profile of Colfax sandy loam In a pas-

light gray to'very dark grayish brown. The B horizons range
from 15 to 50 inches in combined thiekness, and they have a
texture of clay or clay loam instead of sandy clay loam in
some plaees. The eolor of the B horizons ranges from light
olive yellOW to strong brown or gray in hues of 2.51:, 10YR,
-and 7.5YR. Mottles that have the gray eolor of a gleyed soil
are in the uppermost 10 inehes of the B2t horizon. In places
these soils contain a brownish-yellow B1 horizon. The com-
bined thickness of the surface layer and subsoil ranges from
24 inches to 60 inches. Depth to hard rock ranges from 5 to
more than 15 feet.
The Colfax soils occur with Helena and .Worsham soils.
They are less well drained, have less clay in their subsoil,
and are less firm than the Helena soils. The Colfax soils are
better drained than the Worsham soils.
Colfax sandy loam (0 to 6 perce~t slopes) (c~).-This
is the only soil of the Colfax senes mapped III ,Vake
County. It occurs at the heads of drainageways, on fo~t
slopes, and in slight depress.ions. The surface layer IS
light-gray to very dark ~a:r:Ish-brown ~andy 103;m 5 to
20 inches thick. The subSOIl IS 15 to 50 mches thIck and
is light olive-yellow to strong-brown or gray, firm sandy
clay loam or clay loam that is commonly mottled with
brown, yellow, and gray. Inc~uded with this soil in map-
ping were a few areas of a SOlI that has a surface layer of
silt loam. . .
Infiltration is good, and surf.ace runo~ IS medl1pn to
slow. This soil is easy to keep In good t11~h, and It can
be worked throughout a wide range of m?Istu~e . cont~nt.
:Most of the acreage is in forest, but this SOlI IS SUIted
to many of the locally grown crops. The areas that have
been cleared are used chiefly for pasture or waterways.

Congaree Series

The Congaree' series consists of nearly lev~l, well-
drained soils on the flood plains of most ?f the st~eams
in the county. These soils have fo~med In depOSIt;> of
fine loamy material. A seasonally hIgh water table IS at
