Wake County Board of Education Pine Hollow Middle School —
Leesville Church Road Stream Crossing
Raleigh, North Carolina
TWC Project No. 3153 -D
Dear Mr. Lastinger and Ms. Higgins:
The Wooten Company is submitting this application for proposed impacts to waters of
the U.S. in accordance with Department of the Army Nationwide Permit (NWP) No. 39 —
Commercial and Institutional Developments along with supporting documentation. The
Wooten Company has been retained by the Wake County Board of Education (WCBOE),
the applicant for the proposed project, to provide services related to acquisition of the
NWT and corresponding North Carolina Water Quality Certification (WQC) pursuant to
the Clean Water Act.
The project will involve a proposed road crossing of an unnamed perennial tributary of
Sycamore Creek that will result in 147.9 linear feet of permanent stream impact by the
placement of two 6 -ft x 6 -ft reinforced concrete box culverts (RCBC) to accommodate
the stream flow and associated headwall/wingwall structures and 38.68 linear feet of
temporary impact to accommodate the temporary stream diversion during construction
and construction access. Also, the road construction will permanently impact 7,928
square feet of Zone 1 Neuse buffer and 4,842 square feet of Zone 2 Neuse buffer and
temporarily impact 3,624 square feet of Zone 1 Neuse buffer and 2,160 square feet of
Zone 2 Neuse buffer.
In addition, there will be re- construction of a portion of 8 -inch gravity fed sewer line
120 North Boylan Avenue ! under the new roadway extension. The sewer is located within an existing 20 -ft wide City
Raleigh NC 27603 1423 1 of Raleigh easement. The reconstructed sewer in this area will require a slight
modification of the easement; however, the resultant permanent buffer impacts that
919.828.0531
tax 919.834.3589

would be associated with this work are already included in the area due,to the road
construction. This seweranstallation will not impact the stream

BACKGROUND INFORMATION
The location,of the projectaarea,is depicted on the Bay Leaf N C (2013) USGS'
Topographic Map (attached), and the Wake County Soil Survey Map (attached), included
in Attachment,2
The property is located west,of`the intersection of Leesville Church Road and Leesville
Road and immediat6y,south of'Hwy 540 in the northwestern poirtion,of Wake County
The purpose of'the, proposed project is to provide noddle school facilities to the
population surrounding northwest Raleigh and Wfll involve the construction of a new
middle school and,associated facilities, utilities, and,a roadway, extension for traffic
ingress and,egress that ties into an existing road Leesville Church Road.
Tngon Engineering Consultants performed the,original wetland and stream delineation
on May 26,,2006: A copy of this &1meation summary is included in Attachment 3. In
2013, an updated survey was performed by McKim & Creed, Inc with updates made to
the top of stream banks, and Neuse Riparian Buffer delineation to accurately reflect the
stream, and riparian buffer areas within project limits of the proposed �strearn crossing
associated with this project, These features-are incorporated into the master plan and
reflected in the,construction plans.
PROPOSED PROJECT IMPACTS
As mentioned above, the project will involve;a,proposed road crossing of an unnamed
perennial tributary of Sycamore Creek that will "re "s_ult in 147 9 lmear'feei of permanent
stream impact'by the placement of two'6 -ft x 6 -ft reinforced concrete box culverts
(RCBC),to accommodate the stream low and associated headwall/wmgwall structures
and.38.68 linear feet of temporary impact to accommodate the temporary stream'
diversion during construction and construction access Also, the road construction will
permanently impact 7,928 square feet of Zone 1 Neusebufferand 4,842 square feet of
Zone' 2 Neuse buffer- and temporarily impact 3,624 square feet of Zone 1 Neuse buffer
and 2,160 square feet of Zone'2 Neuse buffer

In addition, there will be re- construction of a portion of 8 -inch gravity fed sewer line
under the new roadway extension The;sewer is located within an existing 20 -ft wide City
of Raleigh easement The reconstructed,sewer in this area will require a slight
modification of'the, easement, however, the resultant permanent buffer impacts that
would be associated with this work are already included in the area due to the road
construction This sewer installation will not impact the stream
The Plan and profile details for the proposed project and the location of the stream are
provided in Attachment 4 No jurisdictional wetlands will be impacted as a result of the
proposed development
PROTECTED SPECIES AND CULTURAL RESOURCES
Protected Species
The Wooten Company's review of potential protected species habitat included a review
of existing records obtained from federal and state sources to identify documented
records of protected species The USFWS current list of federally protected species was
consulted for listing of protected species documented within Wake County,, North
Carolina This review identified one protected animal species, no flora is listed Listed
fauna and its federal status are identified in Table 1. Explanations of rankings are
included at the end of the table.

As part of the literature review, The Wooten Company also consulted the North Carolina
Natural Heritage Program NCNHP Geographic Information Systems (GIS) database
Virtual Workroom and Element Occurrence (EO) Database for a listing of EO's of
endangered or threatened species within or near the project area. This review identified
one species of amphibian EO pertaining to federally protected species within a two -mile
radius of the project area The EO is for the Hemidactylcum Scutatum Four -toed
Salamander located within the Umstead State Park southwest of the project area
The GIS search results are illustrated in the attached map included in Attachment 5
A copy of this NWP No 39 application will be provided to the NCNHP and the U S Fish
and Wildlife Service ( USFWS), Raleigh Field Office requesting their review of records
they may have in regards to the proposed project and to provide comments regarding
agency interests
Cultural Resources
The Wooten Company reviewed the HPOWEB GIS Service from the North Carolina
State Historic Preservation Office (SHPO) to review records regarding cultural,
archaeological, or historical resources in or near the project area The GIS search results
are illustrated in the,attached map included in Attachment 5 A copy of this NWP No: 39
application will be provided to SHPO requesting their review of records regarding

cultural, archaeological, or historical resources in or near the project area and to provide
written comments regarding the interests of their agency
AVOIDANCE AND MINIMIZATION
The road extension alignment was dictated by the City of Raleigh Transportation Plan
and existing Controlled Access Right -of -Way of Hwy 540 'The subject, unnamed
tributary (UT) of Sycamore Creek originates north of Hwy 540. When the North Carolina,
Department of Transportation constructed the highway nearly 15 years ago, a 60 -inch
pipe was installed to,convey creek flows under the highway. The 60 -inch pipe projects
through the base of the high, embankment of Hwy 540 and the remaining creek channel at
pipe outlet end is the confluence point for this UT of Sycamore Creek,as it pertains to the
this project The new road extension is proposed to cross this UT of Sycamore Creek
immediately downstream of,the 60 -inch pipe outlet
Construction of the roadway will cross the stream at nearly 90- degrees to minimize
impact to the stream and Neuse riparian buffers Fill slopes.are proposed at 3:1 or steeper
where necessary-to rrunimize fill slope embankments To prevent sedimentation of
downstream portions of the stream, construction will be conducted in the dry through the
use of an impervious,dam, and stabilized temporary stream diversion channel Following
construction, disturbed areas outside of the bank stabilization area will be restored to
original grade, and elevation The proposed project should not result in permanent
changes in pre - construction elevation contours or stream dimension, pattern or profile
beyond those described in this application Excess material will be removed to a high
ground disposal area
Appropriate sediment and erosion control practices outlined in the most.recent version of
the "North Carolina Sediment and Erosion Control Planning and Design Manual" and
approved by the governing authority (NCDENR Land Quality Section) will be in
compliance with specifications governing the proper design, installation, operation and
maintenance of such Best Management Practices (BMP's) to comply with the appropriate
turbidity water quality standard. Sediment and erosion control measures placed in waters
will be removed and the original grade restored within two months after the Division of
Energy Minerals & Land Resources has released the project. Impacts have been avoided
and minimized, and appropriate measures will be taken during construction to allow`flow
and circulation patterns of waters of the U.S to remain unaffected After construction,
disturbed areas will be seeded and restored.
No permanent or temporary impacts to wetlands are anticipated.'The inverts at either end
of the two 6 -ft RCBC culverts will be buried 1 -foot below the stream bed to allow for
aquatic passage of life during low flows
The proposed project will result in an impervious surface amount of 27.08% and all
stormwater from impervious surfaces will be routed to one of two properly sized dry
detention basins to be located on the middle school property Runoff within the public
right -of -way will be collected and conveyed outside of the public right -of -way via the
storm drainage pipe network through private storm,dramage,easements and into the on-
site dry - detention basins The dry detention basins are designed to satisfy the regulatory
requirements of the authority having jurisdiction (City of Raleigh). Each basin will be
configured with an appropriately sized outlet structure and level spreader to discharge
detained volumes of runoff via diffuse flow through the buffer The stormwater

management plan, including control of nitrogen has been submitted to City of Raleigh for
review and approval.
SUMMARY
The proposed permanent impacts to the unnamed perennial tributary of Sycamore Creek
due to the road crossing and culvert installation is 147.9 linear feet, which is below the
150 linear feet threshold requiring mitigation. The proposed permanent impacts to Zone
I and Zone 2 of the Neuse buffer is 12,770 sq. ft. which is less than the 1/3 of an acre
allowable, and will therefore will not require mitigation.

Trigon Project No. 042 -06 -091
Dear Mr. Driscoll:
Trigon Engineering Consultants, Inc. (Trigon) is pleased to provide this report of the survey for wetlands
and streams at the referenced site. This report sununarizes our field methods, observations, and
conclusions.
BACKGROUND
The property is located west of the intersection of Leesville Church Road and Leesville Road and south
of Interstate 540 in the northwestern portion of Wake County, North Carolina (Figure 1). Based on the
Boundary and Topographic Survey you have provided, we understand the project site is approximately
34 acres in size. Two natural drainage features are located in the western portion of the property and a
pond is located adjacent to the property boundary to the south. The site is primarily forested A sanitary
sewer easement and a telephone easement cross the property.
WETLANDS
The site was visited on May 26, 2006 for the purpose of'identifying conditions supporting wetland's. The
methodology used to identify areas suspected of having conditions to support wetlands included walking
the suspected areas to observe existing vegetation, soil characteristics, and hydrology.
Wetlands are defined by the U.S. Army Corps of Engineers (USACE) and the United States
Environmental Protection Agency as "those areas that are inundated or saturated by surface or
groundwater at a frequency and duration sufficient to support, and under normal circumstances, do
support a prevalence of vegetation typically adapted for life in saturated soil conditions." In order for an

area to be classified as wetlands, hydrophytic vegetation, �hydric soils, and wetlands hydrology indicators
must be present. Identification of wetlands was based on the 1987 Corps of Engineers Wetland
Delineation Manual.
An area in the southwestem portion of the site was observed to be inundated arthe time of our site visit,
and areas of wetlands and braided stream channels were observed adjacent to the ,property to the east.
Hand auger soil borings were performed to observe soil and hydrology at multiple locations within the
inundated area. Wetlands were marked in the field with a single ribbon of yellow survey tape. An area
within the property limits of approximately 2.5 acres was determined to be wetlands (Figures 2A, 2B,
,and 2C). Soil observed within, our hand auger ,borings appeared to confirm the mapped soil types. A
copy from Sheet 45 of the Soil Survey of Wake County, North Carolina produced by the USDA Soil
Conservation Service is attached (Figure 3). Vegetation within the wetland area was dominated by
species with obligate indicator status.
STREAMS
Based on our observations at the site, two perrenial stream channels are located within the property
limits: The stream channels were marked in the field with yellow survey tape. One stream channel
originates offsite as a third order stream north of the property. The stream flows approximately 850 feet
to the south and west across the property and exits the western property boundary. The second stream
channel originates at the dam on the property to the east, flows to the north and west across the property
through the wetland area, and exits the western property boundary.
,Surface waters at the site are within the watershed of Sycamore Creek, and within the Neuse River Basin.
Based on the North Carolina Administration Code (15A NCAC 2B .0300), Sycamore Creek and its
tributaries are classified as B waters intended for primary recreation, aquatic life propagation, fishing,
secondary recreation, and agriculture and are nutrient sensitive waters. The state currently requires
buffers extending 50 feet from the top of each stream bank for these surface waters. According to the
City of Raleigh Planning Department, due to the location of the property, it is not subject to city or
county water supply watershed buffers.
13 IN 13 10KI
Surface waters at the site, including the wetlands and two perennial streams, would be considered
jurisdictional "Waters of the United States" regulated under Section 404 and Section 401 of the Clean
Water Act. Section 404 is administered by the USACE. Section 401 is administered by the North
Carolina Department of Environment and Natural Resources Division of Water Quality (DWQ). These
programs regulate the discharge �of dredged or fill material into "Waters of the United States," and ensure
State Water Quality Standards are maintained. Any impacts- to the streams may require permitting.
Impacts may include such activities as placing fill within the stream banks, temporary or permanent
stream crossings, or re- routing or piping the stream channel. It is our recommendation that
representatives of DWQ and USACE be contacted to review the existing conditions at the site and any
proposed impacts to the stream. In our experience this is most beneficial in the planning stages, because
ilie results can often affect the layout of the site and if not initiated in the infancy of the project, the
permitting process could delay construction.
