3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The Caterpillar project comprises 256.07 acres of mixed pine-hardwood upland forest and cleared undeveloped land.
The project extends north from the intersection of NC Highway 42 and Glen Laurel Road, to a large tract of land located
on the southern side of the Neuse River. The southern portion of the project area (approximatley 9.5 acres) consists of a
160-foot public rigth-of-way and a 60-foot private right-of-way for the construction of the Caterpillar access road. The
access road terminates at the proposed Caterpillar Core PDU site which comprises approximatley 247 acres. The project
site is bound to the north and west by wooded or cleared undeveloped land. The Bayer Research Laboratory facilities
are located further to the west of the site, beyond the stand of trees. The project site is bound to the south by wooded
land and NC Highway 42. The project site is bound to the east by wooded land and the Neuse River.
A jurisdictional perennial stream channel (S1) extends (southwest to northeast) through the central portion of the
proposed Caterpillar access road (see Figure 3). Four, small, wetland floodplain areas (bottomland hardwood forest)
abut the perennial stream channel, outside the extents of the proposed access road construction area. A second stream
channel extends through the northern portion of the proposed Caterpillar access road. However, the portion of the
stream reach which occurs on-site (within the project boundaries) is non-jurisdictional (ephemeral).
Four, jurisdictional, intermittent stream channels (SA, SB, SC and SD) have been identified on the Caterpillar Core PDU
portion of the site, which are not located within the areas of proposed development (see Figure 3). The proposed
development will not impact these stream channels or associated buffers. There are additional jurisdictional perenniel
and intermittent stream channels are located along the northern and western property boundaries, respectively.
However, these channels are a significant distance from the proposed development.
Topographic elevations on the project site range from approximately 314 to 140 feet above mean sea level. Surface
water runoff generally is to the northeast to the Neuse River. Figure 4 (attached herein) depicts the location of the
existing property on the U.S. Geological Survey (USGS) topographic quadrangle map (Clayton, NC). Figure 2 (attached
herein) presents the Natural Resources Conservation Service (NRCS) soil map units that occur within the existing
property, as presented on an aerial photograph background (2005 imagery). The existing property boundary which is
depicted on Figures 1 and 3 represents the boundary of the area of investigation for the Jurisdictional Determination for
the proposed Clayton Parkway project. The location of the on-site, U.S. Army Corps of Engineers (USACE) jurisdictional
surface waters, i.e., the limits of the perennial and intermittent stream channels which occur within the project site are
presented on the specific purpose survey. Note: The permit applicant requests that the Notification of Jurisdictional
Determination for the proposed Clayton Parkway project be made a part of the Nationwide Permit 14 (issued permit).
Information on current site conditions is also provided in the attached Stormwater Narrative and Supporting Calculations,
prepared by McKim & Creed, PA for Caterpillar.
3b. List the total estimated acreage of all existing wetlands on the property:
Total wetland acreage within proposed construction area = 0.00 ac.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Total stream linear feet = 192.26 ft., as solely comprised of Stream S1 (perennial).
3d. Explain the purpose of the proposed project:
The southern section (160-foot public right-of-way) of the access road will include a 24-foot wide, two-lane, paved road
with 8-foot unpaved shoulders, measuring approximatley 1,800 feet in length. The paved access road will provide
vehicular access to the Caterpillar Core PDU site and adjacent propertie, which are currently land locked. The northern
section (60-foot private right-of-way) of the access road will include a 24-foot wide, two-lane, gravel road with 2-foot
unpaved shoulders, measuring approximatley 1,200 feet in length. The proposed Caterpillar Core PDC facility will serve
as an equipment testing ground for emitions study, and include a storage building and three equipment testing areas, as
shown on Drawing OP-1.

PCN Form - November 2008 Version
B. Project Information and Prior Project History
3e. Describe the overall project in detail, including the type of equipment to be used:
The proposed Clayton Access Road project, as described in Section 3d, involves the construction of two sections of two-
lane road (public and private sections) to provide access to the proposed Caterpillar Core PDC site. This public section
of the access road will be constructed per NCDOT engineering standards, but is not a NCDOT directed project. The
access road construction will impact 192 linear feet of jurisdictional, perennial stream channel (Stream No. S1),with the
placement of an 8-foot diameter corregated metal pipe (CMP) culvert and subsequent backfilling for the access road. No
dredge or fill impacts are proposed for the four, jurisdictional floodplain wetlands located outside the proposed
construction area. Likewise, the four, intermittent stream channels located on the Caterpillar Core PDU site will not be
impacted by the proposed Core PDC construction. Heavy construction equipment including track excavators, bulldozers,
pans, rubber tired tractors, paving machines and/or dump trucks are anticipated for the proposed construction activities.
Coordination with the prime contractor regarding implementation of construction methodologies that further minimize
permitted impacts to jurisdictional surface waters will be evaluated where feasible. The site development plan and other
pertinent drawings for the proposed Caterpillar Access Road project are included herein. Drawing No. DA-01 is the
project drainage area map. Drawing No. PL-01 is a drawing of the existing site conditions and the proposed segment of
impact of Stream No. S1 (perennial surface water). The profile and cross section of the proposed 8-foot diameter, RCP
culvert, along with the associated inlet and outlet cross sections, are presented on Drawing No. PR-01. The grading plan
for the proposed project is presented in Drawing PL-01. Finally, the design details for the proposed stormwater
management structures are presented in Drawings D-1 and D-2.
4. Jurisdictional Determinations
4a. Have jurisdictional wetland or stream determinations by the
Corps or State been requested or obtained for this property / ® Yes ? No ? Unknown
project (including all prior phases) in the past?
4b. If the Corps made the jurisdictional determination, what type
? Preliminary ®Final
of determination was made?
4c. If yes, who delineated the jurisdictional areas? Agency/Consultant Company:

4d. If yes, list the dates of the Corps jurisdictional determinations or State determinations and attach documentation.
A request for Notification of Jurisdictional Determination was submitted to Mr. Thomas Brown of the Raleigh regulatory
field office of the USACE on September 24, 2008 by MACTEC. A request to review the project for applicability under the
Neuse River Riparian Buffer Rule was provided to Mr. Martin Richmond of the Raleigh office of the North Carolina
Department of Environment and Natural Resources (DENR), Division of Water Quality (DWQ) on September 24, 2008.
On September 30th and November 18th, 2008, site inspections were conducted by Mr. Brown to confirm the landward
limits of USACE regulatory jurisdiction ("Waters of the U.S.") on the proposed Caterpillar Access Road project. The site
inspections were also attended by Mr. Richmond, who determined project applicability under the Neuse River Riparian
Buffer Rule. The Notification of Jurisdictional Determination for the project has not been issued by the USACE at this
time. The binding Jurisdictional Determination will be made a part of the Nationwide Permit 14 for this project, at the time
of issuance of the permit by the USACE. Mr. Richmond provided correspondence, dated November 5, 2008 and January
12, 2009, which presented the results of the review of the project under the Neuse River Riparian Buffer Rule. Copies of
the November 5, 2008 and January 12, 2009 DWQ correspondence are attached herein. A subsequent project planning
meeting was held on April 4, 2009 which included representatives from both USACE and DWQ.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed Caterpillar Access Road project will impact 192 linear feet of jurisdictional, perennial stream channel
(Stream No. S1) with the placement of an 8-foot diameter, RCP culvert and subsequent backfilling for the access road.
No dredge or fill impacts are proposed for the four, jurisdictional floodplain wetlands located outside the construction area.
The road alignment was configured to minimized stream impacts while following the current site topograph and to avoid
impacts to existing wetland areas. Realingment of the stream crossing and modifcation of the vertical roadway alignment
have reduced the linear impact to the stream from 364 linear feet to the current proposed impact of 192 linear feet. The
subsequent reduction in buffer impact is approximately 5,795 square feet. Complete avoidance of this perennial channel
is not feasible, based on the alignment of the proposed access road and the existing topography of the site. Therefore,
the proposed culvert (192 linear feet of stream impact) is required to provide access to the Caterpillar site and adjacent
properties, which are currently land locked.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Coordination with the prime contractor regarding implementation of construction methodologies that further minimize
permitted impacts to jurisdictional surface waters will be evaluated where feasible. A pre-construction meeting, including
the prime contractor,Caterpillar, NCDOT, USACE, DENR, McKim & Creed and MACTEC, will be conducted to formally
establish the limits of proposed impacts.
Sediment/erosion control best management measures have been incorporated into the design of the proposed project.
An Erosion and Sediment Control Plan (ESCP) will be submitted to the Land Quality Section of DENR for review and
approval. The plan will describe the best management practices (BMPs) related to sediment and erosion control, as well
as stormwater management.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or ? Yes ® No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act ® Yes ? No
impacts?

Raleigh
®
5c. If yes, indicate the USFWS Field Office you have contacted. ? Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
The project study area was evaluated in August 2008 by the NCDOT to determine the potential habitat (potential for
occurrence) for federally listed threatened or endangered (T&E) species known to have ranges extending into Johnston
County. The U.S. Fish and Wildlife Service (USFWS) lists five species with federal protection that have a range
extending into Johnston County. These five species include: red-cockaded woodpecker (Picoides borealis); tar
spinymussel (Elliptio stienstansana); dwarf wedgemussel (Alasmidonta heterodon); Michaux's sumac (Rhus michauxii);
and bald eagle (Haliaeetus leucocephalus). Based on the results of the NCDOT evaluation and/or additional on-site
reconnaissance conducted by MACTEC biologists in 2008, it is presumed that there would be No Effect to individuals or
populations of red-cockaded woodpecker, Michauxii's sumac, or bald eagle from the proposed development activities.
Suitable habitat is either not present, or is marginally present but not abundant, for these species. The NCDOT and
MACTEC did not observe the red-cockaded woodpecker or the bald eagle, or their sign, during the site reconnaissance.
Suitable habitat for the Michaux's sumac is not present within the project study area due to the overall density of the
forest canopy; i.e., this species typically thrives in disturbed open areas. The NCDOT also visually inspected the stream
banks of the perennial channel (Stream No. S1), but did not observe individuals of tar spinymussel or dwarf
wedgemussel.
Preferred habitat for Dwarf wedgemussel (Alasmidonta heterodon) is generally associated with large rivers and small
streams with mixed substrates. This bivalve prefers streams situated in a predominantly-wooded landscape with intact
riparian buffers and good water quality. The stream in the project corridor is situated in a wooded landscape near the
stream origin. The baseflow channel within is approximately 18-24 inches wide and the substrate is comprised of sand.
The stream in the project does not provide suitable habitat for this species and therefore is unlikely to support populations
of Dwarf wedgemussel.
Preferred habitat for Tar spinymussel (Elliptio steinstansana) is generally associated with relatively fast-flowing, well
oxygenated water in streams with substrate comprised of relatively sit-free, uncompacted gravel/coarse sand. This
species has had a restricted distribution and is endemic to the Tar River drainage basin. The stream in the project
corridor is situated in a wooded landscape near the stream origin. The baseflow channel within is approximately 18-24
inches wide and the substrate is comprised of sand. The stream in the project corridor does not provide suitable habitat
for this species and therefore is unlikely to support populations of Tar spinymussel.
North Carolina Natural Heritage Program records do not document occurrences of any of the five species within 2.0 miles
of the project corridor.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat? ? Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
The South Atlantic Fishery Management website was accessed by MACTEC, as well as the interactive viewer "South
Atlantic Habitat and Ecosystem IMS," to determine if Essential Fish Habitat encompassed the proposed project area. Based
upon the search of these source databases, it appears that the proposed project area does not include Essential Fish Habitat.

7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal
governments have designated as having historic or cultural preservation 0 Yes ® No
status (e.g., National Historic Trust designation or properties significant In
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
The NC State Historic Preservation Office (SHPO) website was accessed (Department of Cultural Resources, Office of
Archives and History) and a review of the document "NC Listings In the National Register of Historic Places by County
(As of October 22, 2008)" was made. Based on the listing for Johnston County, it appears that there are no historically
listed sites which would encompass the proposed project area.
8. Flood Zone Designation (Corps Requirement)
Sa. Will this project occur in a FEMA-designated 100-year floodplain? 7 ? YQs ® No
8b. If yes, explain how project meets FEMA requirements:
8c. What source(s) did you use to make the floodplain determination? FEMA FIRM 3710100095 D Dated October 20, 2000

Subject: FW: Request for Price Quote forCterpillar Road Project
Jeff and Dicky:
just got back from a long marketing lunch meeting. Anyway, I received this email and am sending it to you both. Please
review the particulars. The mitigation bank is cheaper by EEP as follows: $320 per linear foot stream credit for the Forest
Creek Bank versus $323 at EEP. Buffer credit at the Bank is $0.95 per square foot of impact, while at EEP it is $0.96 per
square foot of impact.

Jim:
? Stream Mitigation Units are currently $320 per SMU.
594 Stream Mitigation Units (594 LFT) would equal $190,080.00
A 25% deposit ($47,520)of total amount will be required with a signing of sales agreement that will result in our
issuance of Unit Reservation Letter to regulatory agencies.
? Riparian Buffer Mitigation is per square feet.
? 70,986 of Riparian Buffer Mitigation is $0.95 per Square foot = $67,436.70
? A 25% deposit ($16,860)of total amount will be required with a signed sales agreement that will result in our
issuance of Credit Reservation Letter to regulatory agencies.
Based on current State Legislation, if a mitigation bank has stream and or buffer credits available to meet compensatory
mitigation requirements, credits must be purchase from the bank, otherwise a letter from the bank must be issues
identifying that the credits are not currently available. Please note that for both stream and buffer credits, Forrest Creek
Mitigation Bank credits are at or below current EEP In-Lieu Fee pricing.
Additionally, our process benefits the purchaser. Most In-Lieu fee programs is pay 100% upfront during the permitting
process. Our process is a deposit to issue the reservation letter, showing that the credits are available and are legally
reserved for a particular project. Also, the balance isn't due until permit approval is received, which normally ties in with
a funding threshold from lenders. Regardless, its less cash out for the applicant up front. For some, this is a benefit.
Below is the process that Steam and Buffer Mitigation credits are purchased. For stream mitigation purchases we work
with Monte Matthews with the ACOE and for Buffer we work with Eric Kulz with the DWQ.
Forest Creek Stream Mitigation Bank is in Neuse 01.
There are (4) documents that are involved with the transfer of credits from an approved mitigation bank.
1. Credit Sales Agreement
2. Reservation Letter
3. Credit Transfer Certificate
4. Bank Ledger
Upon determination by applicant representative that credits from FCMB is applicable, the following course of
action is taken:
? Bank Sponsor and the Applicant will enter into a "Credit Sales Agreement" that legally transfers
mitigation liability to the banker upon full and final execution of legal documents and receipt of
financial deposit.
Upon initial execution and receipt of deposit, a "Reservation Letter" from the Bank Sponsor is provided
confirming that the applicant has legally secured mitigation credits and that the Bank Sponsor will be
legally responsible for providing the amount of credits required upon permit issuance. The
"Reservation Letter" references the amount of credits reserved, type of credits reserved (if multiple
types exist), applicants permit application number, name of project, and the name of purchaser.
The Applicant provides a copy of the "Reservation Letter" along with permit application to the
regulatory agencies as proof of transfer of liability and that the credits have been secured. The
"Reservation Letter" can be sent from Bank Sponsor to Regulatory Reviewer upon request.
Upon approval of permit, the applicant has 10 days to fully execute "Credit Sales Agreement" by
funding remaining balance of "Credit Sales Contract".
Upon full execution, the Bank Sponsor has 5 days to provide the applicant with a "Credit Transfer
Certificate" along with a copy of the bank "Credit Ledger" showing the debit from the bank available
credits referenced by permit application number.
A copy of the "Credit Transfer Certificate" and the "Credit Ledger" will be electronically sent to
reviewer for proof of final execution.
At that time a electronic verification of confirmation will be sent back to Bank Sponsor from regulatory
agency confirming receipt.
Annually, the Bank Sponsor will provide a full Credit Ledger to Regulatory Agency for formal signature
and approval of balance.
Jim, If you have any further questions, let me know.

Rich:
It was good talking to you this morning. The principals on this project are Jeff Mann, PE with McKim & Creed (Raleigh)
and Dicky Harmon (Principal Natural Resource Scientist) with MACTEC (Raleigh). I am providing technical support on
the stream JD and the preparation of the PCN (NWP 14) for the U.S. Army Corps of Engineers and DWQ (Water Quality
Certification and Buffer Rules).
The project is located in Johnston County, east of Clayton. The HU is 03020201. As I understand from recent
conversations with the various mitigation banks that service HU 03020201, your bank (i.e., Forest Creek Mitigation Bank)
is the only bank that currently has credits available for stream impacts and riparian buffer impacts. The project will entail
297 linear feet of impact to a perennial channel (with aquatic function present, etc.). The USACE has identified a 2:1
mitigation ratio for the stream impact. Therefore, I need to know a total cost and a per-unit (per linear foot) cost for
mitigation of amount of 594 linear feet. With regard to the proposed riparian buffer impact, the total square foot impact for
zone 1 and zone 2, as proposed, is 70,986 square feet (after DWQ multiplier of 3 is applied for Zone 1 and multiplier of
1.5 is applied for Zone 2). 1 have a call in to the DWQ biologist to confirm that a 1:1 buffer ratio will apply. Please also let
me know if the buffer mitigation credit has to come through the mitigation bank first (if credits are available), or can the
applicant seek buffer credits at EEP (In-lieu Fee program) separately.
Thank-you,

Dear Dr, Thorpe.
Subject: LCG Mitigation Acceptance Letter;
Division 4 - Access Road from NC 42 to Glen Laurel Road, Johnston
County, WBS Element 57012
The purpose of this letter is to notify you that the Ecosystem Enhancement Grogram
(EP) will provide the stream and buffer mitigation for the subject proiect. Based on the
information supplied by you dated May 18, 2009, the impacts are located in CU 03020201 of the
Neuse River Basin in the Northern Inner Coastal Plain (NICE) l;co-Region, and are as follows-
Stream (Warm): 192.26 feet
Buffer- Zone 1 15,004 square feet
Buffer - Z_one 2 9,770 square feet
All buffer mitigation requests and approvals are administrated through the Riparian
Restoration Buffer Fund. 'I"he NCDOT will be responsible to ensure that appropriate
compensation for the buffer mitigation will be provided in the agreed upon method of fund
transfer. Upon receipt of the NCDWQ's Buffer Authorization Certification, EEP will transfer
funds from 'Fri-Party MOA Fund into the Riparian Restoration Buffer Fund. Upon completion
of transfer payment. NCDOT will have completed its riparian buffer mitigation responsibility for
the above referenced project, Subsequently, EEP will conduct a review of current MOA
Mitigation projects in the river basin to determine if available buffer mitigation credits exist. If
there are buffer mitigation credits available, then the Riparian Restoration Buffer Fund will
purchase the appropriate amount of buffer mitigation credits from Tri-Party MOA_Fund.

PROJECT DESCRIPITON
The purpose of the project is to construct a 24 foot wide road with 8 foot wide unpaved
shoulders that will provide vehicular access to the Caterpillar Core Product Development Center
(PDC) site and adjacent properties, which are currently land locked. The roadway will extend
approximately 1,800 linear feet from the intersection of Glen Laurel Road, toward the northwest,
and will culminate at a proposed gravel drive that will continue towards the Product
Development Center. The PDC facility will serve as an equipment testing ground for emissions
studies and will include a storage building and three equipment testing areas, as shown on
Drawing OP-1.
The access road construction will impact 192 linear feet of a jurisdictional perennial stream,
which will require installation of 140 linear feet of 96" diameter corrugated metal pipe culvert
with aluminum structural plate headwalls. Also, a total of 24,774 sf of riparian buffer (15,004 sf
Zone 1; 9,770 sf Zone 2) will be impacted by the project. The project has been accepted as a
Nationwide 14 Permit by the U.S. Army Corps of Engineers and stormwater will be handled
accordingly.
Through a collaborative effort with the North Carolina Department of Transportation (NCDOT),
the proposed culvert has been designed to mimic the natural sinuosity of the stream in which
the culvert will be installed. A series of baffles will be used to lengthen the average daily flow of
water through the pipe. End sills on either end of the pipe will be used to create a channelized
flow into and out of the pipe that closely simulates the existing channel geometry. Both internal
pipe structures will also serve to dissipate the flow inside the culvert structure such that there will
be no negative impacts to downstream areas. The pipe will also be buried 1 foot to provide a
stream bed that replicates the existing natural stream bed which will allow normal passage of
aquatic life.
Upon completion of the project construction, the 24' wide paved road will be turned over to
NCDOT.
SITE DESCRIPTION
The existing site is a 160' Right of Way extending to the northwest from the intersection of NC 42
and Glen Laurel Road. The total project boundary is approximately 6.84 acres. The total
disturbed acreage for the project site is 8.18 acres. Temporary construction easements will be in
place for land disturbance that takes place outside of the project's boundaries.
A jurisdictional perennial stream channel extends from southwest to northeast through the
central portion of the proposed Caterpillar access road.
The tract has elevations ranging from 315' above Mean Sea Level (MSL)to 225' MSL and includes
a stream which is a 'U.S. Army Corps of Engineers' surface water, and is a direct tributary to the
Neuse River.
The average slope over the site is around 7%, however several localized areas have existing
grades in excess of 15%.
SOILS
According to the Johnston County Generalized Soil Survey, the majority of uplands within the site
are classified as Cecil sandy loam (Ce) and Pacolet loam (Pa). Interspersed are small pockets
of Urdorthents loamy. Along the banks of the Neuse River are the frequently flooded Wahadkee
loam (Wt) and Chewacla loam (Ch). The following soil descriptions are associated with the soils
found on the site:
CeB - Cecil sandy loam at 2 to 6% slopes
NoB - Norfolk loamy sand at 2 to 6% slopes
PaD - Pacolet loam at 10 to 15%
PaE - Pacolet loam at 15 to 25%
Ud - Urdorthents loamy
STORMWATER IMPROVEMENTS
This project will provide stormwater management based on the guidelines set forth in the North
Carolina Division of Water Quality's Stormwater Best Management Practices Manual.
Based on impervious areas in relation to the site acreage, the project can be classified as low
density according to the "BMP Manual" in that the total impervious area for the site is less than
24%:
46,149sf * 100% =15.48%
297,963sf
Furthermore, each individual drainage area of the site can be classified as low density (See
attached SWU-101 Drainage Areas breakdown). To determine an overall stormwater
management strategy for the project, we broke the project into 5 drainage basins that
represent the overall final drainage patterns for the site.
Our findings have concluded that:
A. For drainage area # 1, channelized stormwater runoff will captured in an open throat
inlet and piped into an existing natural draw. By utilizing this draw, the amount of
runoff that would enter the Neuse River Buffer untreated will be greatly reduced.
Initially, stormwater will be dissipated along the eastern side of the road in the open
throat inlet. It will be further dissipated on the western side of the road by means of a
preformed scour hole located at the outlet of the road's cross pipe. The channelized
flow on the west side of the road will also be dissipated in the preformed scour hole.
B. In drainage area #2, channelized stormwater runoff will be captured in a drop inlet
and piped directly into the proposed culvert. The water will be dissipated in the drop
inlet structure then once again as it enters the 96" diameter culvert pipe. In the
culvert, the baffling and end sills will simulate the natural stream geometry so as to
further dissipate flow and such that there will be no negative impacts to downstream
areas.
C. In drainage area #3, channelized stormwater runoff will be captured in a double
grated drop inlet and piped into an existing natural draw. By utilizing this draw, the
amount of runoff that would enter the Neuse River Buffer untreated will be greatly
reduced. Initially, stormwater will be dissipated along the roadside in the drop inlet
structure. It will be further dissipated by means of a preformed scour hole located at
the outlet of the pipe.
D. In drainage area #4, channelized stormwater runoff will be captured in a double
grated drop inlet and piped into a storm drainage manhole and then into an existing
natural draw. Initially, stormwater will be dissipated along the roadside in the double
grated drop inlet structure. By utilizing a secondary manhole, runoff will be dissipated
twice before it reaches the outlet. The manhole allows the pipe slopes to be
shallower and allows a drop to further dissipate the erosive flows. Runoff will be
further dissipated by means of a preformed scour hole located at the outlet of the
pipe. By utilizing the existing draw, the amount of runoff that would enter the Neuse
River Buffer untreated will be greatly reduced.
E. In drainage area #5, no runoff will be channelized. All runoff will sheet flow into
existing natural draws that lead to a tributary to the Neuse River.
MAINTENANCE CONSIDERATIONS
The property owner shall be responsible for periodic inspection and maintenance of all
permanent indicated stormwater devices. Any measure that fails to function as intended shall
be repaired immediately.

PERFORMANCE SPECIFICATION
AMERCAN NOS" SC250
GREEW
The composite turf reinforcement mat (C-TRM) shall be a machine-produced mat of 70% straw/30% coconut
fiber matrix incorporated into a permanent three-dimensional turf reinforcement matting.
The matrix shall be evenly distributed across the entire width of the matting and stitch bonded between heavy
duty UV stabilized top and bottom nets with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings and an ultra heavy duty
UV stabilized, dramatically corrugated (crimped) intermediate netting with 0.50 x 0.50 inch (1.27 x 1.27 cm)
openings. The middle corrugated netting shall form prominent closely spaced ridges across the entire width of
the mat. The three nettings shall be stitched together on 1.50 inch (3.81 cm) centers with UV stabilized
polypropylene thread to form a permanent three-dimensional turf reinforcement matting.
