©n beh2if of the NC ~2 East, LLC, STViRalph Whitehead Associates, Inc. (STV!R ~'v A} in
cooperation with IC2 Engineering PLLC (IC2) is submitting a Pre-Constructio.~
Notification (PCN) application form (Attachment A) in accordance with Gene~~al
Condition No. 13 and pursuant to U.S. Anny Corps of Engineers (USAGE) Section 40^
Nationwide Permit (NWP) #39. NC 42 East, LLC has contracted STV/RWA to be ?h;,
actir;g agent and perform wetland-permitting services for this project that is called "42
East." An Agent Certification of Authorization Form is included (Attachment B) and
was included in the Request for a Jurisdictional Determination (Attachment D).
Acecrlpanying figures related to this permit request are included in Attachment C.
The project site is approximately 332.69 acres in size and is located between the towns of
Clayton and Flowers on the south side of NC 42. The project site is bounded by NC 42
to tl;e north, and the Neuse River to the south (Attachment C, Figures t and 2).
Approximately 14,280 linear feet (lf) of streams and 5.4 acres of freshwater wetlands are
located on the project site, as indicated on the Existing Conditions plan (Attachment 1,).
NC 42 East, LLC has proposed a road crossing of two tributaries to Mill Creek in order tc
access the ,developable upland portions of the property. Proposed plans for the roadway
will result in impacts to approximately 293 If of two jurisdictional perennial streams. In
addition, impacts to wetlands potentially resulting from site grading, and utility
installation will not exceed 0.08 acre. Impacts to regulated riparian buffers will not
exceed 0.92 acres.

Previous Master Plan Design
The original master plan for the proposed roadway included additional stream crossings
within the proposed project site. The project would have involved the filling and piping
of Streams A, E, and I, and the filling of Wetlands GG. The original master plan was
subsequently revised to eliminate the crossing of Stream I to reduce the proposed
impacts. The revised project plan eliminated one of the crossings, and was also designed
to avoid certain sensitive areas (including the Mill Creek and Neuse River floodplains)
and to minimize impacts to wetland and stream features. The revised master plan
includes the stream crossings of Streams A and E, with impacts (fill and pipe) totaling
less than a total of 300 linear feet (lf). These proposed crossings have been relocated and
redesigned to limit impacts to a total of approximately 293 lf, which would depict a
minimization of stream impacts from the revised master plan that had proposed over 760
linear feet of impacts (See Attachment C -Exhibit B). This minimization was achieved
by excavating in excess of 500,000 cubic yards of material in an effort to lower the
vertical elevation at the crossings.
Current Master Plan
The proposed development will be comprised of seven sections of development within a
Planned Unit Development (PUD) comprising 332.69 acres. This PUD has been
approved by the Johnston County Planning Department. Development will be located on
287.13 acres of the tract and impervious surfaces will total 76.67 acres or 23.05% of the
site. The PUD will include a strip of commercial buildings along the NC 42 East
frontage and a recreational lot that will include parking area, a clubhouse, a swimming
pool, and tennis courts. The remaining development will consist of 441 residential units.
The current proposed master plan includes a total of two stream road crossings (Streams
A and E) that would require piping. The crossing on Stream A (Impact Area 4, Creek
Crossing G) will impact 134 linear feet of stream and will require the installation of 90
linear feet of 54" pipe to convey the steam flow under the proposed roadway with 24
linear feet of riprap at the pipe outlet. The crossing on Stream E (Impact Area 5, Creek
Crossing H) will impact 159 linear feet of stream and will require the installation of 90
linear feet of 48" pipe to convey the stream flow under the proposed roadway with 21
linear feet of riprap at the pipe outlet. See Attachment C -Figures 4 and 5 for the current
proposed plan views, profiles and typical sections for each of the two crossings.
Engineering plans for the remainder of the development that have been prepared by IC2
are enclosed as Attachment F. Representative photographs of Streams A and E at the
location of the proposed road crossings are included in Attachment G.
The on-site sewer will have six proposed stream crossings on-site. Five of the stream
crossings will use a jack and bore method to cross under the stream to avoid stream and

minimize buffer impacts. One of the sewer crossings will use an aerial crossing to avoid
stream impacts and minimize buffer impacts.
Minor wetland impacts will result from the site grading required for the development of
residential lots and sewer line installation. Wetland Area HH has an area of 0.037 acre
(1,604 sq. feet), and approximately 0.02 acre (871 sq. ft.) of Wetland HH will be
impacted (Attachment F, Impact Area 7). Wetland Area LL has an area of 2.341 acres
(101,994 sq. feet), and approximately 0.04 acre (1,742 sq. ft.) of Wetland LL will be
impacted (Attachment F, Impact Area 9). Wetland II has an area of 0.107 acre (4,677 sq.
ft.), and approximately 0.01 acre (487 sq. ft.) will be impacted (Attachment F, Impact
Area 2). Wetland FF has an area of 0.0724 acre (3,154 sq. ft.), and approximately 0.01
acre (336 sq. ft.) will be impacted (Attachment F, Impact Area 2).
The primary entrance into the development is located on the south side of NC 42,
approximately 300 feet east of Mill Creek. This entrance has been established to align
with a future crossover included in NCDOT's proposed improvements to NC 42. The
project will also include the construction of turning lanes on eastbound and westbound
NC 42 as well as a 'right in, right out' entrance east of the main entrance in order to
access the proposed commercial component of the PUD. An entrance road for the
western residential development area will also be constructed. The construction of the
turning lanes on NC 42 will include the construction of a retaining wall along the
northern side of NC 42. This retaining wall has been proposed in order to avoid impacts
to the unnamed tributary to Mill Creek that is located parallel to NC 42. Minor impacts
to the riparian buffer (492 sq. ft.) will occur from grading to accommodate the turning
lanes.
The sanitary sewer forcemain will extend from the pump station serving the development
to the west, along the south side of NC 42 for a distance of approximately 5000 feet. At
the western end, the sewer forcemain will cross under NC 42 to the north side (near
Bennet Place) and terminate at an existing sewer junction. The .sewer forcemain will
cross over or under four stream channels along NC 42. Impacts to these stream channels
will be avoided by directional drilling (jack and bore) underneath the stream channels to
be crossed or by crossing over the culvert conveying the stream flow. The sewer
forcemain will be connected to a proposed pump station located on the subject site that
will be situated east of Mill Creek and south of Stream E.
A Stormwater Management Plan has been prepared for this project to document the
design process and to develop the stormwater management system for the development.
This Stormwater Management Plan has been prepared by IC2 and has been included in
Attachment E. NC 42 East; LLC understands and is committed to providing a
stormwater management plan that achieves NCDWQ design parameters, for concentrated
impervious areas on the subject site.

Purpose and Need
Page 4
The purpose of the project is to provide adequate affordable residential housing
opportunities within the region that has convenient access to commercial shopping areas
for the residents and the general public. NC 42 East, LLC anticipates beginning
construction in 2007 in order to achieve an opening of the first residential units at the end
of 2007. This schedule will allow NC 42 East, LLC to take advantage of the rapid
residential/commercial/retail growth currently dominating this region of Johnston
County. Construction will result in impacts to waters of the U.S., as described in the
impacts section below.
The roadway crossings of Stream A and E have been proposed to access the uplands in
the central portion of the site. The developable portion of the site would not be
accessible without these proposed crossings, and would result in an economic hardship if
the stream crossings were denied. The alignment of the internal roadways was designed
to avoid the streams as well as the stream buffers to the greatest extent practicable in
order to reduce the amount of impacts that would occur while achieving NCDOT design
parameters of a collector road. The road crossing impacts have been reduced to the point
where the development would qualify for a Nationwide Permit #39. The impacts to the
stream channels are included in the mitigation calculations prepared for this project. A
concerted attempt has been made to minimize the disturbances to these two stream
channels and their associated regulated riparian buffers.
Impacts to Waters of the U.S.
Total related grading, piping, riprap, and fill activities associated with the construction of
the proposed internal roadway will result in permanent impacts to approximately 293 if
of jurisdictional perennial streams (Stream A=134 lf, and Stream E=159 lf).
The first stream crossing in the northern portion of the project site (Stream A, Impact
Area 4, Creek Crossing G) would require the installation of 90 linear feet of 54" diameter
pipe underneath the proposed roadway to provide continued conveyance of the stream
flow. The bottom portion of the pipe will be buried one foot (minimum) below the
existing steam bed to ensure continued stream flow and aquatic organism passage in
periods of low flow conditions. Stabilization of the pipe outlet will require 24 linear feet
of riprap. A total of 134 linear feet of stream will be impacted at this crossing location.
The second stream crossing (Stream E, Impact Area 5, Creek Crossing H) will require the
installation of 90 linear feet of 48" diameter pipe underneath the proposed roadway to
provide continued conveyance of the stream flow. The bottom portion of the pipe will be
buried one foot (minimum) below the existing steam bed to ensure continued stream flow

and aquatic organism passage in periods of low flow conditions. Stabilization of the pipe
outlet will require 21 linear feet of riprap. A total of 159 linear feet of stream will be
impacted at this crossing location. Proposed impacts are summarized in Table 1 below.
Reference Attachment C, Figures 4 and 5 for locations and details of stream impacts.
Minor wetland impacts will result from the site grading required for the development of
residential lots and sewer line installation. Wetland Area HH has an area of 0.037 acre
(1,604 sq. feet), and approximately 0.02 acre (871 sq. ft.) of Wetland HH will be
impacted (Attachment F, Impact Area 7). Wetland Area LL has an area of 2.341 acres
(101,994 sq. feet), and approximately 0.04 acre (1,742 sq. ft.) of Wetland LL will be
impacted (Attachment F, Impact Area 9). Wetland II has an area of 0.107 acre (4,677 sq.
ft.), and approximately 0.01 acre (487 sq. ft.) will be impacted for the sewer (Attachment
F, Impact Area 2). Wetland FF has an area of 0.0724 acre (3,154 sq. ft.), and
approximately 0.01 acre (336 sq. ft.) will be impacted (Attachment F, Impact Area 2). A
total of 0.08 acre of wetland will be impacted (See Table 2 below).
Regulated riparian buffers associated with the Neuse River basin waterways are present
on most of the streams located on site. These buffers are 50 feet wide and are regulated
by the North Carolina Department of Environment and Natural Resources (NCDENR)
pursuant to 15A NCAC 2H .0506. All surface waters that are depicted on either the
USGS topographic quadrangles, or the County Soil Surveys within the Neuse River basin
have 50-foot regulated buffers. Surface waters that do not appear on either of the two
aforementioned maps do not have a regulated buffer. Road crossings of streams and
other surface waters that are subject to Neuse River Buffer rules are regulated based on
the length and area impacted by the crossing (Note: Road crossings of the regulated
buffer that would impact equal to or less than 40 if of the buffer are exempt from the
rules). Road crossings that impact more than 40 if of riparian buffer but equal to or less
than 150 lf, or one-third of an acre of buffer are allowable under the rules. Road
crossings that impact greater than 150 lf, or one third of an acre of riparian buffer, are
allowable with mitigation.
Sewer crossings on the site will be limited to less than 40 feet in width and are therefore
exempt from the buffer rules. As mentioned above, five of six proposed sewer crossings
will be accomplished via directional drilling with the exception of one aerial crossing.
Temporary buffer impacts may occur at each location, but will be within the established
corridor shown on the plans. No disturbance will occur within 10 feet of the top of
stream bank in any of these locations. The crossings will be returned to original grade
and revegetated when construction is completed. The site grading, which has been
minimized to the greatest practical extent within the buffer areas, is also an exempt
activity. These areas will be vegetated and sheet flow will be maintained throughout the
buffer.

The NC 42 East project proposes to impact 159 if and less than one-third of an acre of
buffer for the crossing of Stream E Impact Area 5, Creek Crossing H, site grading and
sewer installation, and therefore is allowable with mitigation under the Neuse River
buffer rules. Neuse River buffer impacts are summarized in Table 3.
Neuse River buffer impacts resulting from the crossing of Stream A, Impact Area 4,
Creek Crossing G will total 7,413.92 sq. ft. in Zone 1 and 5,511.01 sq. ft in Zone 2. The
crossing of Stream E, Impact Area 5, Creek Crossing H will total 8,242.17 sq. ft. in Zone
1 and 2,504 sq. ft in Zone 2. The NC 42 turning lane site grading will impact 49 sq. ft. in
Zone 1 and 201 sq. ft in Zone 2 of an unnamed tributary to Mill Creek located on the
north side of the retaining wall north of NC 42. In addition, fill from minor widening of
NC 42 for the turn lane will impact 63 sq. ft. in Zone 1 and 179 sq. ft in Zone 2 of Mill
Creek, south of NC 42. Impact area 1 includes 2,105 sq. ft. of Zone 2 impacts for sewer
installation and site grading. Impact area 2 includes 4,414 sq. ft. of Zone 2 impacts for
sewer installation. Impact area 3 includes 186 sq. ft. of Zone 2 impacts for site grading.
Impact area 6 includes 2,917 sq. ft. of Zone 2 impacts for site grading. Impact area 7
includes 1,836 sq. ft. of Zone 2 impacts for site grading. Impact area 8 includes 2 sq. ft.
of Zone Z impacts for the aerial sewer crossing installation. Impact area 10 includes 1,606
sq. ft. of Zone 2 impacts for site grading. Impact area 11 includes 1,988 sq. ft. of Zone 2
impacts for site grading. Impact area 12 includes 322 sq. ft. of Zone 2 impacts for
roadway grading. Impact area 13 includes 213 sq. ft. of Zone 2 impacts for roadway
grading. See Attachment F for the impact maps prepared by IC2.

Avoidance and Minimization
In an effort to avoid and minimize impacts to jurisdictional stream crossings (Stream A,
Impact Area 4, Creek Crossing G and Stream E, Impact Area 5, Creek Crossing H),
measures and strategies have been considered and utilized throughout the project
planning process. These strategies and reduction measures include the following:
• Lowering the vertical grade of the entrance road at the stream crossings (Note:
This strategy will result in a significant increase in earthwork costs due to
additional excavation of approximately 500,000 cubic yards @ $4/cy)
• Use of wingwalls*
• Elimination of guardrails and use of curb and gutter
• Use of 11-foot lanes instead of the 12-foot NCDOT standard*
• Maximization of fill slopes to 2:1
• Elimination of medians
• Entrance road and turning lanes to the development area from NC 42 were shifted
east to avoid extension of the existing NC 42 culvert, thereby avoiding impacts to
Mill Creek and associated floodplain (The location of the entrance road along NC
42 East is being dictated by the critical need to align the entrance with the planned
crossover that will accompany the proposed future widening of NC 42 East.)
• Retaining wall along the north side of NC 42 will be constructed to avoid stream
impacts and minimize buffer impacts
• Reduction of entrance road from a 4-lane divided section to a 3-lane undivided

section prior to the first stream crossing
• Site grading and proposed construction limits have been adjusted to minimize
buffer and wetland impacts
• Lots are mostly located outside riparian buffers to avoid future land use changes
to the buffers
• Undisturbed wetlands and/or streams on lots will be platted and recorded as
easements to prevent future impacts
• Sewer force main along NC 42 has been designed to avoid stream impacts
• On-site sewer will be bored or directionally drilled under stream or will cross by
aerial to avoid stream impacts and minimize buffer impacts
• Elimination of access roads and development within the Neuse River floodplain
• Preservation of sensitive Neuse River and Mill Creek floodplain habitat through
inclusion in open space easements and/or Johnston County Land Dedication
Program
• Elimination of a crossing of Mill Creek, one of which would have provided access
to high value lots along the Neuse River.
• Avoidance of the high quality wetlands found on site.
*Theee reduction measures were the result of negotiations with NCDOT's District
Engineer.
Compensatory Mitigation
The Council on Environmental Quality (CEQ) has defined mitigation in 40 CFR Part
1508.20 to include: avoiding impacts, minimizing impacts, rectifying impacts, reducing
impacts over time, and compensating for impacts. Three general types of mitigation
include avoidance, minimization and compensatory mitigation. Mitigation efforts for this
project included avoidance and minimization of impacts to jurisdictional waters of the
U.S. and the preservation of approximately 14,280 linear feet of stream and 5.32 acres of
wetlands that are located on site.
The NCDENR Ecosystem Enhancement Program (EEP) is willing to accept an In-Lieu
Fee Payment as the method to provide compensatory mitigation for the proposed impacts
to the wetlands and stream channels. The fee for one acre of riparian wetland impacts
purchased from the EEP is $27,847 (valid from 7/1/06 until 7/1/07). Wetland mitigation
credits are sold by the EEP in one-quarter acre increments (10,890 sq. ft.). Therefore, the
compensatory wetland impact fee for the project would be $6,961.75 to mitigate for 0.08
acre of riparian wetland impacts. The fee for a linear foot of stream impacts purchased
from the EEP is $232 (valid from 7/1/06 until ?/1/07). At 1:1 impacts to mitigation ratio,
the compensatory stream impact fee for the project would be $67,976.00 to mitigate for
293 if of stream impacts. The fee for riparian buffer impacts purchased from the EEP is
$0.96 per square foot (valid from 7/1/06 until 7/1/07). Therefore, the compensatory

STV/Ralph Whitehead Associates
Mr. Jamie Shern
March 2, 2007
Page 10
riparian buffer impact has been calculated to be $27,343.21 to mitigate for 8,242.17 sq ft
of Zone 1 and 2,504 sq. ft. of Zone 2 riparian buffer impacts.
The combined fee for wetland, stream and riparian buffer impacts would be $102,281.00.
In addition to making an in-lieu fee payment to the EEP, NC 42 East, LLC also proposes
to preserve all remaining wetlands (5.32 acres) and streams (14, 2801f) on site, as well as
all remaining riparian buffers on site. These preservation areas will be preserved in
perpetuity through covenants of the homeowners association as dedicated open space or
as part of Johnston County's Land Dedication Program.
Protected Species
RWA conducted a protected species habitat assessment and review of the project area in
July 2006. Prior to the field site visit, RWA reviewed the North Carolina Natural
Heritage Program (NCNHP) database, which provided existing data concerning the
potential occurrence of federally threatened and endangered species in Johnston County.
This database indicates that there are five federally threatened or endangered species that
may occur in Johnston County, as described below:
Michaux's sumac (Rhus michauxii) -Federally Endangered - Michaux's sumac is a
rhizomatous, densely hairy shrub, with erect stems from 1 to 3 feet in height. The
compound leaves contain evenly serrated, oblong to lanceolate, acuminate leaflets. Most
plants are unisexual; however, more recent observations have revealed plants with both
male and female flowers on one plant. The flowers are small, borne in a terminal, erect,
dense cluster, and colored greenish yellow to white. Flowering usually occurs from June
to July, while the fruit, a red drupe, is produced through the months of August to October.
Michaux's sumac grows in sandy or rocky open woods in association with basic soils.
Apparently, this plant survives best in areas where some form of disturbance has
provided an open area. There have been no documented populations of this plant in
Johnston County within the last 50 years and is listed as a historic occurrence, meaning
that it was last observed more than 50 years ago.
Bald eagle (Haliaeetus leucocephalus) -Federally Threatened -This bird (federally
proposed for de-listing) nests in mature live pines or cypress trees in the transition zone
between mature forests and large bodies of water. Nests are very large, up to six feet in
width, and constructed of large sticks and soft materials such as dead vegetation, grasses,
and pine needles. Nesting trees are usually less than two miles from open water. Winter
roosts are usually in mature trees, similar to nesting trees, but may be somewhat farther
from water. Female bald eagles are approximately 35 to 37 inches long while the male
bald eagles are approximately 30 to 34 inches. Adults tend to have ablackish-brown
back and breast with a white head, neck, and tail and a yellow bill. Juveniles tend to be
brown and white with a black bill.

Threatened Species of the Southeastern United States (The Red Book) FWS Region 4.)
Red-cockaded woodpecker (Picoides borealis) -Federally Endangered -Adult red-
cockaded woodpeckers (RCWs) are approximately 18 to 20 cm long with a wingspan of
35 to 38 cm. Adults have a black cap, throat, aild stripe on the side of the neck and white
cheeks and underparts. The back is barred with black and white horizontal stripes. Adult
males have a small red spot on each side of the black cap. The bird is native to southern
pine forests and typically nests within open pine stands with trees 80 years or older.
Roosting cavities are excavated within live pines, which are often infected with a fungus
which causes what is known as red-heart disease. Foraging may occur in pine andlor
mixed pine/hardwood stands 30 years or older with trees 10" or larger in diameter at
breast height {dbh).
{Reference: U.S. Fish a.ld Wildlife Service. 1985. Recovery Plan for the Red-cockaded
Woodpecker. U.S. Department of the Interior, Fish and Wildlife Service, Atlanta,
Georgia. 88 pages.)
Dwarf wedgemussel (Alasmidonta heterodon) -Federally Endangered -The dwarf
wedgemussel rarely exceeds 45 mm in length. Young shells are typically greenish-brown
in color with greenish rays, while older shells usually appear black or brown. The shell is
relatively thin, but tends to thicken with age toward the anterior end. The preferred
habitat of this species includes clay banks along root systems of trees, mixed substrates of
cobble, gravel, and sand, and occasionally soft silt substrates. Stream banks are stable,
having extensive root systems and mature riparian buffers. Water quality within the rivers
and streams where the dwarf wedgemussel is found is good to excellent. Dwarf
wedgemussel once occurred in rivers and streams from New Brunswick, Canada to North
Carolina. North Carolina supports the greatest number of known occurrences within the
Neuse River Basin (Orange Co., Wake Co., Johnston Co., Wilson Co., Nash Co.), and the
Tar River Basin (Person Co., Granville Co., Vance Co., Franklin Co., Warren Co., Nash
Co., and Halifax Co.)
Tar River spinymussel (Elliptio steinsta~zsa»a) Federally Endangered -The Tar River
spinymussel is 2.5 inches in length. Juvenile mussels contain twelve spines and have an
outer shell surface that is orange-brown with greenish rays. Adult mussels tend to lose
their spines as they mature and have a darker outer surface with inconspicuous rays. The
imler shell of both the juvenile and adult mussel is yellow or pinkish at one end and
bluish-white at the other end. This species is typically observed in unconsolidated beds
of gravel and coarse sand in relatively fast flowing water. The water quality of the stream
is good to excellent. Stream banks are usually stable, having extensive root systems. The
Tar River spinymussel is known to occur in Edgecombe County within the Swift Creek
subbasin and the Tar River. This mussel has also been observed within Johnston County
(Little River subbasin-Neuse River Basin), Nash County (Swift Creek subbasin and Tar

River), Franklin County (Shocco and Sandy Creek subbasins), and Halifax County (Little
Fishing Creek Subbasin).
The list of federally protected species was reviewed, and evaluations were performed
regarding the likelihood of the presence of each species within the subject site.
STV/RWA environmental scientists, Rhett Baggett and Steven Busbee, performed a field
review of the subject site in July 2006. No individuals of any of the aforementioned plant
or animal species were observed during the field visit. The majority of the study area
consists primarily of upland forest and upland fields. However, no individuals of these
protected species were observed during the field visit.
According to a letter received from the NCNHP (Attachment H), three State Threatened
mussel species are located in the general vicinity of the project area. These species are:
Creeper (Stropliitus undulates)
Roanoke Slabshell (Elliptio roanokensis)
Eastern Lampmussel (Lampsilis radiata radiate)
Each of these species has been documented in the Neuse River approximately one mile
upstream of the project site. Therefore, these species may occur within the Neuse River
adjacent to the proposed development site. Proper sediment barriers will be put into
place prior to development activities to ensure that sedimentation does not reach the river.
In addition, the development will be subject to a stormwater management plan designed
to remove total suspended solids emanating from concentrated impervious areas of the
site. Finally, extensive floodplain areas along the Neuse River will be preserved as part
of the proposed project.
Considering the limited amount of potential habitat in the study area, the likelihood that
these Federally and State list species are present on the subject property is concluded to
be remote.
Cultural Resources
The State Historic Preservation Office (SHPO) has previously reviewed two projects that
occurred proximal to the proposed development and had no comment on either (See
SHPO Correspondence, Attachment H). Considering the limited size of the project area
impacting waters of the U.S. for this project, the likelihood of cultural resources being
present in the proposed permit area is considered remote. The applicant would be willing
to perform an archaeological survey of the proposed permit areas as a condition of the
requested nationwide permit.

Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: Based on Johnston County Technical Services aerial
photo~ra~hy the~roiect area includes nine parcels which consists mostly of undeveloped.
woodlands and omen fields The floodplains associated with the Neuse River and Mill Creek
are completely forested and the open fields of the uplands are primarily maintained pasture.
Land adjacent to the site consists mostly of undeveloped woodland with scattered residential
areas.
Potential jurisdictional waters of the U S in the project area include multiple unnamed
tributaries to Mill Creek (Streams A B E F I J K L M P V and W) Mill Creek and the
Neuse River Nine p_alustrine forested wetlands are located on-site and include Wetlands
AA BB CC EE FF II LL MM1 and RR These wetlands exhibited moderate to strong
herbaceous groundcover and an overstory of mature trees. Amid-story of shrubs and small
trees was also typically present Six emergent herbaceous wetlands are located on-site and
include Wetlands KK MM2 PP Q~ SS and UU. These wetlands exhibited strong
herbaceous groundcover and weak to moderate coverage of shrubs. Nine wetland seeps are
located on-site and include Wetlands DD GG HH JJ, NN, 00, TT, VV, and WW. These
wetlands were typically located on moderate to strong slopes and exhibited persistent flow,
weak to strong herbaceous groundcover and a loam~ocky substrate (refer to Attachment
~ _.
10. Describe the overall project in detail, including the type of equipment to be used:
The proposed development will be comprised of seven sections of development within a
Planned Unit Development (PUD) comprising 332 69 acres. This PUD has been approved
by the Johnston County Planning Department Development will be located on 287.13 acres
of the tract and impervious surfaces will total 76.67 acres or 23.05% of the site. The PUD
will include a strip of commercial buildin sg_ along the NC 42 East frontage and a recreational
lot that will include parkin area a clubhouse a swimming pool and tennis courts. The
remainin d'g_evelopment will consist of 441 residential units.
The current proposed master plan includes a total of two stream road crossings (Streams A
and E) that would require piping The crossing on Stream A (Impact Area 4, Creek Crossing
G will impact 134 linear feet of stream and will require the installation of 90 linear feet of
54" pipe to convey the steam flow under the proposed roadway with 24 linear feet of riprap
at the pipe outlet The crossing_on Stream E (Impact Area 5 Creek Crossing H) will impact
159 linear feet of stream and will require the installation of 90 linear feet of 48" pipe to
convey the stream flow under the proposed roadway with 21 linear feet of riprap at the pipe
outlet See Attachment C -Figures 4 and 5 for the current proposed plan views, profiles and
* ;apical sections for each of the two crossings. En ing eering_plans for the remainder of the
development that have been prepared by IC2 are enclosed as Attachment F. Representative
photographs of Streams A and E at the location of the proposed road crossings are included
in Attachment G.
The on-site sewer will have six proposed stream crossings on-site. Five of the stream
crossings will use a iack and bore method to cross under the stream to avoid stream and
Page 3 of 14

minimize buffer impacts. One of the sewer crossings will use an aerial crossing to avoid
stream impacts and minimize buffer impacts.
Minor wetland impacts will result from the site rg ading_ required for the development of
residential lots and sewer line installation. Wetland Area HH has an area of 0.037 acre
(1,604 sq. feet ,and approximately 0.02 acre (871 sq. ft.~ of Wetland HH will be impacted
(Attachment F, Impact Area 7). Wetland Area LL has an area of 2.341 acres (,101,994 scp
feet), and approximately 0.04 acre (1,742 sq. ft.) of Wetland LL will be impacted
Attachment F, Impact Area 9). Wetland II has an area of 0.107 acre (4,677 sq; ft. and
approximately 0.01 acre (487 sq. ft.) will be impacted (Attachment F, Impact Area 2).
Wetland FF has an area of 0.0724 acre (3,154 sq. ft. ,and approximately 0.01 acre (336 sq.
ft.) will be impacted (Attachment F, Impact Area 2~
The primary entrance into the development is located on the south side of NC 42,
approximately 300 feet east of Mill Creek. This entrance has been established to align with a
future crossover included in NCDOT's proposed improvements to NC 42. The ~roiect will
also include the construction of turning lanes on eastbound and westbound NC 42 as well as
a 'right in, right out' entrance east of the main entrance in order to access the proposed
commercial component of the PUD. An entrance road for the western residential
development area will also be constructed. The construction of the turning lanes on NC 42
will include the construction of a retaining wall along the northern side of NC 42. This
retaining wall has been proposed in order to avoid impacts to the unnamed tributary to Mill
Creek that is located parallel to NC 42. Minor impacts to the riparian buffer (492 sq. ft., will
occur from grading to accommodate the turnin lanes.
The sanitary sewer forcemain will extend from the pump station serving the development to
the west, along the south side of NC 42 for a distance of approximately 5000 feet. At the
western end, the sewer forcemain will cross under NC 42 to the north side (near Bennet
Place) and terminate at an existing sewer junction. The sewer forcemain will cross over or
under four stream chamlels along NC 42. Impacts to these stream channels will be avoided
by directional drilling (jack and bore) underneath the stream channels to be crossed or by
crossing over the culvert conveying the stream flow. The sewer forcemain will be com~ected
to a proposed pump station located on the subject site that will be situated east of Mill Creek
and south of Stream E.
A Stormwater Management Plan has been prepared for this project to document the design
process and to develop the stormwater management system for the development. This
Stormwater Management Plan has been prepared by IC2 and has been included in
Attachment E. NC 42 East, LLC understands and is committed to providing a stormwater
management plan that achieves NCDWO design parameters for concentrated impervious
areas on the subject site.
Typical equipment, including bulldozers, rg ading pans and track hoes will be used for
construction of the entrance road and site ading_
11. Explain the purpose of the proposed work:
Page 4 of 14

The purpose of the project is to provide adequate affordable residential housing opportunities
within the region that has convenient access to commercial shopping areas for the residents
and the general public NC 42 East LLC anticipates beginning construction in 2007 in order
to achieve an opening of the first residential units at the end of 2007. This schedule will
allow NC 42 East, LLC to take advantage of the rapid residentiaUcommerciaUretail growth
currently dominatin tg his region of Johnston County Construction will result in impacts to
waters of the U S as described in the impacts section below.
The roadway crossings of Stream A and E have been proposed to access the uplands in the
central portion of the site The developable portion of the site would not be accessible
without these proposed crossings and would result in an economic hardship if the stream
crossings were denied The alignment of the internal roadways was designed to avoid the
streams as well as the stream buffers to the greatest extent practicable in order to reduce the
amount of impacts that would occur while achieving NCDOT design parameters of a
collector road The road crossing impacts have been reduced to the point where the
devel~ment would qualify for a Nationwide Permit #39. The impacts to the stream
channels are included in the mitigation calculations prepared for this project A concerted
attempt has been made to minimize the disturbances to these two stream channels and their
associated regulated riparian buffers.
IV. Prior Project History

for this project The Jurisdictional Request was made on 7/14/06 and 9/29/06 (Forcemain
component)
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
No future permit requests are anticipated on the 333 acre subiect site.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
Page 5 of 14

permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs maybe 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.
1. Provide a written description of the proposed impacts:
Total related grading piping ripra~ and fill activities associated with the construction of the
proposed internal roadway will result in permanent impacts to approximately 293 if of
jurisdictional perennial streams (Stream A=134 if and Stream E=1591f).
The first stream crossing in the northern portion of the project site (Stream A, Impact Area 4,
Creek Crossing G) would require the installation of 90 linear feet of 54" diameter pipe
underneath the proposed roadw~ to provide continued conveyance of the stream flow. The
bottom Rortion of the pipe will be buried one foot (minimum) below the existing steam bed to
ensure continued stream flow and aquatic or ang ism passage in periods of low flow conditions.
Stabilization of the pipe outlet will require 24 linear feet of riprap. A total of 134 linear feet of
stream will be impacted at this crossing location.
The second stream crossing (Stream E Impact Area 5, Creek Crossing H) will require the
installation of 90 linear feet of 48" diameter pipe underneath the proposed roadway to provide
continued conveyance of the stream flow. The bottom portion of the pipe will be buried one foot
(minimum) below the existing steam bed to ensure continued stream flow and aquatic organism
passage in periods of low flow conditions. Stabilization of the pipe outlet will require 21 linear
feet of riprap A total of 159 linear feet of stream will be impacted at this crossing location.
Proposed impacts are summarized in Table 1 below. Reference Attachment C Figures 4 and 5
for locations and details of stream impacts.
Minor wetland impacts will result from the site grading required for the development of
residential lots and sewer line installation. Wetland Area HH has an area of 0.037 acre (1,604
sq feet) and approximately 0 02 acre (871 sq ft) of Wetland HH will be impacted (Attachment
F Impact Area 7) Wetland Area LL has an area of 2.341 acres (101,994 sq. feet), and
approximately 0 04 acre (1 742 sq ft) of Wetland LL will be impacted (Attachment F Impact
Area 9) Wetland II has an area of 0.107 acre (4,677 sg. ft.), and approximately 0.01 acre (487
sq ft.) will be impacted for the sewer (Attachment F, Impact Area 2). Wetland FF has an area of
0 0724 acre (3 154 sq ft) and approximately 0.01 acre (336 sg. ft.) will be impacted
(Attachment F Impact Area 2). A total of 0.08 acre of wetland will be impacted (See Table 2
below .
Regulated riparian buffers associated with the Neuse River basin waterways are present on most
of the streams located on site. These buffers are 50 feet wide and are regulated by the North
Carolina Department of Environment and Natural Resources (NCDENR) pursuant to 15A
NCAC 2H .0506. All surface waters that are depicted on either the USGS topographic
quadrangles or the County Soil Surveys within the Neuse River basin have 50-foot re ug_lated
Page 6 of 14

buffers Surface waters that do not appear on either of the two aforementioned maps do not have
a regulated buffer Road crossings of streams and other surface waters that are subtect to Neuse
River Buffer rules are regulated based on the length and area impacted by the crossing (Note:
Road crossings of the regulated buffer that would impact equal to or less than 40 if of the buffer
are exempt from the rules) Road crossings that impact more than 40 if of riparian buffer but
equal to or less than 1501E or one-third of an acre of buffer are allowable under the rules. Road
crossings that impact greater than 1501f or one third of an acre of riparian buffer, are allowable
with miti atg ion.
Sewer crossings on the site will be limited to less than 40 feet in width and are therefore exempt
from the buffer rules As mentioned above five of six proposed sewer crossings will be
accomplished via directional drilling with the exception of one aerial crossing. Temporary
buffer impacts may occur at each location but will be within the established corridor shown on
the plans No disturbance will occur within 10 feet of the top of stream bank in any of these
locations The crossings will be returned to on final ade and revegetated when construction is
completed The site rg ading which has been minimized to the egr atest practical extent within
the buffer areas is also an exempt activity These areas will be vegetated and sheet flow will be
maintained throughout the buffer.
The NC 42 East proiect proposes to impact 159 if and less than one-third of an acre of buffer for
the crossing of Stream E Impact Area 5 Creek Crossing H site r~ ading and sewer installation,
and therefore is allowable with mitigation under the Neuse River buffer rules. Neuse River
buffer impacts are summarized in Table 3.
Neuse River buffer impacts resulting, from the crossing of Stream A, Impact Area 4, Creek
Crossing G will total 7 413 92 sq ft in Zone 1 and 5 511.01 sg. ft in Zone 2. The crossing of
Stream E Impact Area 5 Creek Crossing H will total 8 242.17 sq. ft. in Zone 1 and 2,504 sg. ft
in Zone 2 The NC 42 turning lane site rg ailing will impact 49 sq. ft. in Zone 1 and 201 sg. ft in
Zone 2 of an unnamed tributary to Mill Creek located on the north side of the retaining wall
north of NC 42 In addition fill from minor widening of NC 42 for the turn lane will impact 63
sq ft in Zone 1 and 179 sq_ft in Zone 2 of Mill Creek south of NC 42. Impact area 1 includes
2 105 sq ft of Zone 2 impacts for sewer installation and site rg ailing. Impact area 2 includes
4 414 sq ft of Zone 2 impacts for sewer installation. Impact area 3 includes 186 sq. ft. of Zone
2 impacts for site rg ailing Impact area 6 includes 2 917 sq. ft. of Zone 2 impacts for site
grading Impact area 7 includes 1 836 sq ft of Zone 2 impacts for site grading. Impact area 8
includes 2 sq ft of Zone 2 impacts for the aerial sewer crossing installation. Impact area 10
includes 1 606 sq ft of Zone 2 impacts for site_g ading_ Impact area 11 includes 1 988 sq. ft. of
Zone 2 impacts for site~rading_Impact area 12 includes 322 sq. ft. of Zone 2 impacts for
roadway grading Impact area 13 includes 213 sq. ft. of Zone 2 impacts for roadway grading.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It maybe 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 an effort to avoid and minimize impacts to jurisdictional stream crossings (Stream A, Impact
Area 4 Creek Crossing G and Stream E Impact Area 5 Creek Crossing H) measures and
strategies have been considered and utilized throughout the project planning process. These
strategies and reduction measures include the following:
• Lowering_the vertical grade of the entrance road at the stream crossings (Note: This
strategy will result in a significant increase in earthwork costs due to additional
excavation of approximately 500 000 cubic a~rds__n, $4/cy)
• Use of wingwalls*
~ Elimination of guardrails and use of curb and gutter
• Use of 11-foot lanes instead of the 12-foot NCDOT standard*
• Maximization of fill slopes to 2:1
• Elimination of medians
Page 9 of 14

• Entrance road and turning lanes to the development area from NC 42 were shifted east to
avoid extension of the existing NC 42 culvert thereby avoiding impacts to Mill Creek
and associated floo~lain (The location of the entrance road along NC 42 East is being
dictated b_y the critical need to align the entrance with the planned crossover that will
accompany the~roposed future widening of NC 42 East.)
• Retaining wall along the north side of NC 42 will be constructed to avoid stream impacts
and minimize buffer impacts
• Reduction of entrance road from a 4-lane divided section to a 3-lane undivided section
prior to the first stream crossing
• Site rg ading and proposed construction limits have been adjusted to minimize buffer and
wetland impacts
• Lots are mostly located outside riparian buffers to avoid future land use changes to the
buffers
• Undisturbed wetlands and/or streams on lots will be platted and recorded as easements to
prevent future impacts
• Sewer force main along NC 42 has been designed to avoid stream impacts
• On-site sewer will be bored or directionally drilled under stream or will cross by aerial to
avoid stream impacts and minimize buffer impacts
• Elimination of access roads and develoRment within the Neuse River floodplain
• Preservation of sensitive Neuse River and Mill Creek floodplain habitat through inclusion
in open space easements and/or Johnston County Land Dedication Program
• Elimination of a crossing of Mill Creek one of which would have provided access to
high value lots along the Neuse River.
• Avoidance of the high quality wetlands found on site.
*These reduction measures were the result o~~otiations with NCDOT's District En,~ineer.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that maybe 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.
Page 10 of 14

If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http ://h2o. enr.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.
The Council on Environmental Quality_(CEQ) has defined mitigation in 40 CFR Part
1508 20 to include• avoiding impacts minimizing impacts rectifying impacts, reducing
impacts over time and compensatin fg or impacts Three general types of mitigation include
avoidance minimization and compensatory mitigation. Mitigation efforts for this project
included avoidance and minimization of impacts to jurisdictional waters of the U.S. and the
preservation of approximately 14 280 linear feet of stream and 5.32 acres of wetlands that are
located on site.
The NCDENR Ecosystem Enhancement Program (EEP is willing to accept an In-Lieu Fee
Payment as the method to provide compensatory mitigation for the proposed impacts to the
wetlands and stream channels The fee for one acre of riparian wetland impacts purchased
from the EEP is $27 847 (valid from 7/1/06 until 7/1/07). Wetland mitigation credits are sold
by the EEP in one-quarter acre increments (10 890 sq. ft.). Therefore, the compensatory
wetland impact fee for the project would be $6 961 75 to mitigate for 0.08 acre of riparian
wetland impacts The fee for a linear foot of stream impacts purchased from the EEP is $232
(valid from 7/1/06 until 7/1/07). At 1:1 impacts to mitigation ratio, the compensatory stream
impact fee for the project would be $67 976.00 to mitigate for 293 if of stream impacts. The
fee for riparian buffer impacts purchased from the EEP is $0.96 per square foot (valid from
7/1/06 until 7/1/07) Therefore the compensatory riparian buffer impact has been calculated
to be $27 343 21 to mitigate for 8 242 17 sq ft of Zone 1 and 2 504 sq. ft. of Zone 2 riparian
buffer impacts.
The combined fee for wetland stream and riparian buffer impacts would be $102 281.00. In
addition to making an in-lieu fee payment to the EEP NC 42 East LLC also proposes to
preserve all remaining wetlands (5.32 acres) and streams (14 280 lfl on site, as well as all
remaining riparian buffers on site. These preservation areas will be preserved in perpetuity
through covenants of the homeowners association as dedicated open space or as part of
Johnston County's Land Dedication Pro rg am.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For

STORMWATER MANAGEMENT PLAN

STORMWATER MANAGEMENT PLAN
42 East Development
Clayton, North Carolina
1.0 PURPOSE
The purpose of this Stormwater Management Plan (SMP) is to document the design
process used to develop the stormwater management system for the 42 East
Development, south of NC 42. This SMP describes the stormwater management and
control features included in the hydraulic design for the Project. This design was
performed by professional engineers with involvement from environmental scientists, the
owner, and contractors. This SMP has been prepared in general accordance with the
North Carolina Department of Environment and Natural Resources (NCDENR)
Stormwater Best Management Practices manual (July 2005 Draft), the Neuse River:
Nutrient Sensitive Waters Management Strategy (15A NCAC 02B .0232-.0236), and the
Johnston County Stormwater Design Manual and Stormwater Ordinance.
2.0 PROJECT DESCRIPTION
The Project includes seven sections of development within a Planned Unit Development
(PUD) comprising 332.69 acres south of NC 42. This PUD, approved by Johnston
County Planning Department, consists of the following:
• Section F - A residential section of 22.63 acres consisting of 24 lots. Proposed
impervious. area of 18.1 %.
• Section G - A commercial development of 27.90 acres directly adjacent to NC
42. Proposed impervious area of 60%.
• Section H - A residential section of 36.3 acres consisting of 36 lots. Proposed
impervious area of 14.4%.
42 East 1 2/28/2007
Stormwater Management Plan

• Section I - A residential section of 58.9 acres consisting of 180 lots. Proposed
impervious surface area of 29.9%.
• Section J - A residential section of 30.24 acres consisting of 107 lots. Proposed
impervious surface area of 36%.
• Section K - A residential section of 102.88 acres consisting of 94 lots.
• Recreation Area - An 8.28 acre recreational facility to serve all of the above
developments. Proposed impervious surface area of 50%
Overall the total development includes 76.67 acres or 23.05% impervious area. Sections
I and J have complete BMP designs and detailed calculations of flows, since these initial
phases have been fully designed. The plans are currently under review by Johnston
County. The remaining sections have been laid out on a conceptual level and the
associated stormwater management facilities are also conceptual. These are provided to
ensure that the future sections aze able to comply with County and State standards for
stormwater quality and quantity management, and that sufficient room is set aside for
BMPs. If requested, final stormwater management plans for each section will be
submitted as final designs are completed for each section.
3.0 SITE BACKGROUND INFORMATION
The site is located between NC 42, Mill Creek, and the Neuse River, with several
intermittent to perennial tributaries dividing the property. With the exception of the two
main road crossings and unavoidable sewer line crossings, impacts to these systems have
been avoided. Minor impacts to wetlands adjacent to these stream systems are discussed
in the permit application, along with the major crossing impacts.
All streams within the site are classified as Class C -NSW (Nutrient Sensitive Waters)
by NCDENR. The stream channels described in the permit application have been field
verified by NCDWQ as under the jurisdiction of the Neuse River Riparian Buffer Rules.
The site is not located in an environmentally sensitive overlay district as listed by
Johnston County.
42 East 2 2/28/2007
Stormwater Management Plan

The site is a mixture of open fields and forested areas. The flood plain of Mill Creek and
the Neuse River are completely forested, while the upland areas are predominantly
maintained pasture. Topography on the sites consists of several ridges running east-west
between the natural drainage ways. These ridges are relatively flat, but have steep side
slopes as they approach the stream channels.
4.0 BMP Evaluation Criteria
Due to the sensitive nature of the watershed, best management practices (BMPs) were
evaluated at all outfall locations. During the evaluation, the following conditions were
considered:
• The percent impervious area in each development section.
• The pre- and post-project stormwater flow at the outfall location and across the
entire site.
• The proximity of the location to surface waters and riparian buffers.
• The slope and consistency of the topography between the outfall and the
environmentally sensitive area (buffers, wetlands, and streams).
• The proximity of the BMP to the roads or lots and any potential safety hazards
involved.
• Access and maintenance issues critical to the continued operation and success of
each BMP.
• Existence of natural, non jurisdictional channels or structures for use in routing
stormwater flows.
• Nitrogen loading rates for each section.
42 East 3 2/28/2007
Stormwater Management Plan

5.0 BMP EVALUATION
The following steps were followed to determine the applicability of using BMPs at each
location:
• Evaluate the use of a level spreader, including flow volume and velocity, length
required, slope, and consistent topography.
• Provide sheet flow and/or treatment at each outfall in proximity to riparian
buffers.
• Determine if there is a significant change in pre- and post-project stormwater
flows.
• Evaluate the use of a wet detention pond, if necessary, to reduce post-project
stormwater flows and provide adequate treatment and nitrogen reduction.
Based on this evaluation, BMPs were implemented in each development section as
described below.
6.0 DESIGN DETAILS
The following sections describe the BMPs used in each section of the project. As
mentioned above, the BMP design is conceptual in nature for the future sections
(F,G,H,K, recreational area) and final design is provided for the initial sections (I,J). The
conceptual design ensures that all stormwater management goals and requirements can be
achieved given the preliminary lot layout. If required as part of the permit conditions,
final stormwater system designs will be submitted prior to commencement of
construction of each section.
6.1 General BMP Design
Runoff attenuation and treatment are provided to the maximum extent practical in
each section of the project. Wet detention ponds are located in each section to
provide the maximum attenuation and water quality benefits. These ponds are
designed to the standards described in the Johnston County Stormwater Design
42 East 4 2/28/2007
Stormwater Management Plan

Manual and the July 2005 NCDENR Updated Draft Manual of Stormwater Best
Management Practices. Pond design include forebays and permanent pools of at
least 3-foot depth with calculated water quality volumes to meet or exceed the
proposed impervious surface requirements of the drainage
Level spreaders were not able to be implemented in Sections I and J due to the
steep topography on site, and the maximum level spreader slope requirement of
8%. Traditional infiltration trenches were also considered, but the site soils
prevented their use. Therefore, where ponds could not be provided an alternate
BMP strategy was devised to handle storm system outfalls.
The BMP chosen at riparian buffer locations is a combination level spreader and
infiltration trench that would provide some attenuation of the initial "first flush"
rainfall as well as some treatment through a filter fabric and sand layer. The
storm system outlet would discharge runoff into a plunge pool, which would
reduce the velocity of the runoff. Stormwater would then flow through a
vegetated swale to the trench. The stormwater infiltrating through the trench
would then be collected in 4-inch perforated drain pipes and discharged through
an energy dissipater pad in an upland area outside the buffers at non-erosive
velocities. Larger rain events would collect in the trench and then spill over a
curb provided on the "down-hill" side of the ditch designed to create sheet flow
into the buffer. The enclosed details show the design of this level
spreader/infiltration trench.
6.2 Section F
Section F consists of low density development and has a proposed impervious
area of 4.09 acres or 18.1 %. The cul-de-sac will have a storm system draining the
road and much of the development. This system will outlet outside the riparian
buffer into either a wet detention pond at the lower end of the site or a device
which creates sheet flow into the buffer depending on final design calculations.
42 East 5 2/28/2007
Stormwater Management Plan

6.3 Section G
The design of the commercial area has not been completed at this time since it is
likely to change depending on the type of enterprise that purchases each lot.
Therefore, the conceptual stormwater management system for this area has been
designed for a maximum 60% impervious area. This maximum will be
incorporated into the deed for each lot as it is sold. If individual owners need
additional impervious area, they will be required to provide additional stormwater
treatment and attenuation on their individual lots. Two wet detention ponds are
designed to provide adequate treatment and attenuation of the entirety of this
highly impervious area, based on the 60% impervious maximum.
6.4 Section H
Section H is a proposed low density residential development with only 14.4%
impervious area. Since it generally drains toward the proposed recreational
facility, much of the impervious area will be routed to the storm system in the
road and discharged into a wet detention pond located below the recreational area.
The remaining stormwater drainage will be limited to the backs of the lots and
overland flow into the buffer.
6, 5 Section I
Section I is a higher density cluster of residential lots, with a proposed impervious
area of 29.9%. The majority of this area, including most of the roads and lots,
will drain to a wet detention pond (Pond 3) located in the floodplain of Mill
Creek. This wet pond will outlet outside the buffer into an energy dissipator after
providing both treatment and attenuation of the site stormwater. The outlet will
provide low velocity discharge to a point at the toe of the slope where the
topography is flat and non-erosive velocity at the outfall would not impact the
buffer. The remaining areas not routed to the pond will be discharged at the
buffer through the level spreader/infiltration trenches described in Section 6.1.
42 East 6 2/28/2007
Stormwater Management Plan

6.6 Section J
Section J consists of a clustered residential area with a proposed impervious area
of 36.0%. In order to provide treatment and attenuation for this area, two wet
ponds have been designed: one in Section J and one just across the road in
Section I. The majority of drainage from this residential area is captured in these
ponds, which meet the criteria described in Section 6.1. Pond 4 discharges into an
energy dissipater at the edge of the buffer. Pond 5 discharges into an upland
drainage approximately 90 feet from the riparian buffer. Energy dissipaters are
provided to lower velocities and prevent erosion within the buffer. The remaining
bypass areas are directed to level spreader/infiltration trenches described in
Section 6.1.
6.7 Section K
Section K is the largest residential section within the proposed development,
consisting of 102 acres and 15.2% impervious area. This area will not be
designed or constructed for 3 to 5 years. The conceptual stormwater management
design includes three wet detention ponds designed to capture most of the runoff
from this area. The presence of the extensive Neuse River flood plain adjacent to
this section allows for adequate room to treat this large area. Any additional areas
that cannot be routed to the ponds due to site topography will discharge into level
spreader/infiltration trenches or traditional level spreaders if topography allows.
6.8 Recreational Area
The recreational area proposed adjacent to Section H will be limited to 50%
impervious area. The entire area will be drained to a wet detention pond that will
also collect and treat runoff from Section H.
6.8 Roadway Drainage
Due to the extensive minimization of stream impacts performed during the
planning and design of this project, the main road entrance will have low points at
or near the two stream crossings. Stormwater from the road surface will be
captured and piped to the wet detention ponds in Sections G and H. The
42 East 7 2/28/2007
Stormwater Management Plan

remaining sections are incorporated into the stormwater design for each section of
the development. This impervious area was included in the sizing of the wet
detention ponds.
7.0 CONCLUSION
The proposed stormwater management system is designed to be an integrated system of
appropriate BMPs that effectively control and treat on-site stormwater for this
development. This plan is consistent with both Federal, State, and County regulations
and guidance. Please refer to the enclosed plans for more information. The operation
and maintenance of the proposed BMPs will be ensured via Johnston County Inspection
and Maintenance agreements and recorded in restrictive covenants for the development.

This acceptance is valid for six months from the date of this letter. 1:f we have not received a copy of the issued 404
Pernnit/401 Certification within this time frame, this acceptance will expire. It is the applicant's responsibility to send
copies of the 404/401/CAMA permits to NCEEP. Once NCEEP receives a copy of the 404 Permit and/or the 401
Certification an invoice will be issued and payment must be made. The amount of the In Lieu Fee to be paid to NCEEP by
an applicant is calculated based upon the Fee Schedule and policies listed at www.nceep.net.
Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the

Upon receipt of payment, EEP will take responsibility for providing the compensatory mitigation. If the regulatory agencies
require mitigation credits greater than indicated above, and the applicant wants NCEEP to be responsible for the additional
mitigation, the applicant will need to submit a mitigation request to NCEEP for approval prior to permit issuance. The
mitigation will be performed in accordance with the Memorandum of Understanding between the N. C. Department of

Mach species was ~faund in the Ncuse River in 2001 adjacent to the NG ~2 bridge, roughly a mile
upstream ol'the site. 'T'hese species can thus be eYpe.cted to occur in the river adjacent to•the tractlproject

during, construction to make sure that sedimentation does not rez-ch the river.

Dear ~1r. Iagrwcca:
'T'ltarrk ~~ott for your letter of august l3, 20()6, concerning tike above project,
~~'e 11avc revie~~~cd two projecxs that fall ~r~ithin theproposeddevelopment. "~L'hey were CT Ol-U92$, a cell tower,
and LR (76-0911, a wood waste facility. We grad no comment an either since they were to he on low probability
areas, attributed either to topography or previatts disturbance. With the exception of the=se arras, we feel that the
eopographic and hydrologi.ctl situation of the proposed development make it of high probability for the location
cyf arch,~tcolagical sites.
Sites 31:)"I'350 through 3`1JT357 were recorded in 2002 in a similar setting; about one mile to the cast of the
pea:7posed project area. Possibly recorded in conjunction with a proposed residential development, these sites have;
tine been assessed to determine their eligibility for the National Register of I-3istoric Places.
1~`e recommend that a eornprehensive su~>.-vey be conducted of the NC 42 East, LLC, tract by an experienced
arch;aeoloc;ist to identih~ and evaluate the sig7rtificance of archacola~rical remains that may he damaged or destroyed
by the proposed project. Potential effects on unknown resources must be assessed prior to the initiation of
constructior) activities.
'T'wo copies of the restilung archaeological survey report, as well as one copy of the appropriate site forms, should
be forwarded to us for rec~iexv and con>~ent as soon as they=are available and. well ~in ads once of any construction
acti~~itica.
~ list of archaeological consultants who have conducted or expressed an interest in contract worl~ in h?c)rth
Carolina is availahie at v~nc.arch.dcrstate.nc.t.)sjco.nsults. The archaeologists listed, or any ether experienced
arcltaeolcigist., may be cantacled to conduct the recommended survey.
