17. DIRECTIONS TO THE SITE
The Johnston Regional Airport (JNX, Airport) is located on Swift Creek Road approximately 0.6 mile southwest of the intersection of
Swift Creek Road with U.S. Highway 70 Business northwest of Smithfield, NC.
18. Nature of Activity (Description of project, include all features)
The proposed Midfield Apron Development project encompasses approximately 100 acres and can be divided into three general areas: the
Midfield Apron Development (Midfield Development), submerged gravel stormwater treatment wetland, and the borrow area. The entire
project is located on Airport property. The Midfield Development site is an approximately 49-acre site on the west side of the airfield,
midway between the ends of the Airport's only runway. Approximately 21 acres of the 49 acres of the Midfield Development would be
used for hangars, aprons, taxilanes, and taxiways. The remaining area would accommodate relocating an access road, installation of a
small stormwater treatment facility, and expansion of the stormwater treatment system for the Midfield Development. The Midfield
Development area was selected because it meets the Federal Aviation Administration (FAA) design requirements, is enclosed within the
Airport security fence, and has easy access to Airport services and facilities. The submerged gravel stormwater treatment wetland area
occupies approximately 18 acres and will be installed southeast of the runway and will occupy the site of a former stormwater treatment
facility that is no longer maintained or functional. Lastly a 31-acre borrow site will be utilized to provide fill for this project.
19. Project Purpose (Describe the reason or purpose of the project, see instructions)
The purpose of the proposed project is to provide safe and efficient aviation facilities to meet current and projected demand and meet
current FAA design standards. The Airport has 126 based aircraft and is projected to have 171 based aircraft within the 20-year planning
horizon. Per the 2022 Master Plan Update, the Airport has the following storage facilities: T-hangars (46 units), Box hangars (4 buildings),
Fixed Based Operators (FBO) (5 buildings), and Corporate hangars (11 buildings). JNX is currently unable to accommodate existing
demand for hangar space and the proposed project will address a portion of the demand. With an estimated 34 hangars of various sizes, the
proposed project could accommodate an estimated 34 to 56 aircraft, depending upon the size of the aircraft. A submerged gravel
stormwater treatment wetland will be constructed to treat the additional stormwater produced by increased impervious surface. The borrow
area will produce a portion of the fill required to construct the Midfield Development.
USE BLOCKS 20-23 IF DREDGED AND/OR FILL MATERIAL IS TO BE DISCHARGED
20. Reason(s) for Discharge
The Midfield Development site will be converted from forestland to an aviation apron hosting approximately 34 new hangars. This area
will be filled and paved in preparation for construction of hangars and the associated taxiway. A submerged gravel stormwater treatment
wetland will be constructed southeast of the runway in an area that is partially forested and currently contains jurisdictional wetlands and
streams. Approximately 18.67 acres of wetlands will be filled to construct both facilities. Approximately 1,389.7 feet of stream will be
filled, piped, or diverted in construction of this project.

Project Information
Name of Project: Johnston Regional Airport (JNX, the Airport) Midfield Apron Development
Location: Johnston County, North Carolina (35.544095 N,-78.39282 W). Major stream systems include
Reedy Branch (offsite but adjacent), Swift Creek (offsite but adjacent) (Attachment A).
Project Description:
This project is located within the Airport property in Smithfield, Johnston County, North Carolina (NC).
JNX is a full -service, public use, general aviation airport and is accessed from Swift Creek Road, one mile
southwest of US 70-BUS. The Airport also provides additional services to transient aircraft traveling to and
from the Triangle region of NC and destinations in proximity to Smithfield, NC. Collectively, the Airport
is used by business, recreation, military, police, and medical evacuation aircraft and helicopters. The
project area encompasses 100.2 acres and includes the proposed Midfield Apron Development area, borrow
area, and submerged gravel stormwater treatment wetland area (Attachment A).
The proposed Midfield Apron Development (Midfield Development) would be located on the west side of
the airfield on Airport property on an approximately 49-acre largely forested site located between existing
corporate and general aviation hangars. The proposed Midfield Development would accommodate
approximately 34 aircraft hangars for use by individual aircraft owners. The Midfield Development would
be phased based on the Airport's ability to finance construction of the hangars and would include a
combination of various aircraft storage facilities (hangars). The Midfield Development would include
aprons, taxiways, and taxilanes needed to provide access for aircraft between the hangars and the airfield.
The Midfield Development also includes a proposed linear dry pond and level spreader that would be
located on the western edge of the Midfield Development. The linear dry pond and level spreader would
carry runoff to the north and west into the riparian buffer of Swift Creek.
The submerged gravel stormwater treatment wetland area (submerged gravel wetland) would be located
east of the airfield on approximately 18 acres of forested wetland. The borrow area is located north of the
submerged gravel wetland on approximately 31 acres of upland grasses.
The project area consists of a mixture of aviation infrastructure, maintained grassed lanes, and forest stands.
Forests consist of a mixture of mature hardwoods including red maple (Acer rubrum), tulip poplar
(Liriodendron tulipifera), sweetgum (Liquidambar styracijlua), and loblolly pines (Pious taeda) in both the
Midfield Development and submerged gravel wetland areas. The submerged gravel wetland area contains
a former stormwater treatment facility that is no longer maintained or functioning properly per NC
Department of Environmental Quality (NCDEQ) regulations. The former stormwater treatment facility is
currently inundated with water and has wetland emergents such as wool grass (Scirpus cyperinus) and soft
rush (Juncus effusus) along with shrubs such as tag alder (Alnus serrulata) occupying the "pond" margins.
The borrow area northeast of the proposed submerged gravel wetland area is a grassy field that is maintained
regularly to preserve the grassy character beneficial for airport safety and operations.
Surrounding land uses include primarily industrial and commercial uses to the north and west, and vacant
and farmland to the east and south. Very few residences are located in the immediate airport area. There
is one residence across Swift Creek Road from the northeast corner of the site and another approximately
350 feet north of the site on Rock Pillar Road.
Purpose and Need:
The purpose of the proposed project is to provide safe and efficient aviation facilities to meet current and
projected demand while adhering to current Federal Aviation Administration (FAA) design standards. The
Airport has 126 based aircraft and is projected to have 171 based aircraft within the 20-year planning

horizon. According to the 2022 Master Plan Update, the Airport has the following storage facilities: T-
hangars (46 units), Box hangars (4 buildings), Fixed Based Operators (FBO) (5 buildings), and corporate
hangars (I I buildings).
The Airport is currently unable to accommodate existing demand for hangar space and the proposed project
will address a portion of the demand. More than 70 customers are currently waiting for hangars at JNX.
Johnston County maintains two waiting lists for customers looking for facilities to store aircraft and/or
conduct business, one each for small box/T-hangars and for corporate/business hangars. The lists are
updated annually to identify and remove potential customers who have found storage at another airport or
are otherwise no longer interested in a hangar at JNX. As a result, 60 individuals are still on the updated
list for a small box or T-hangar at JNX and 11 individuals or businesses are still on the list for a large
corporate hangar. With an estimated 34 hangars of various sizes, the proposed project could accommodate
an estimated 34 to 56 aircraft, depending upon the size of the aircraft.
Proposed Impacts to Waters of the U.S.
There are approximately 1,389.7 linear feet of freshwater streams and 18.67 acres of freshwater wetlands
located within the proposed project's limits of disturbance (LOD). Additionally, there will be 74,624 square
feet of impacts to Zone 1 Neuse River riparian buffer and 48,757 square feet of impacts to Zone 2 Neuse
River riparian buffer. A large portion of the Neuse River riparian buffer impact areas (58,800 square feet)
are located within wetlands that are being impacted and mitigated for, and thus will not require additional
Neuse River riparian buffer mitigation. Individually listed impacts for the proposed project are provided in
Tables 1, 2, and 3. Drawings showing the proposed stream and wetland impacts can be found in Attachment
B.
A Preliminary Jurisdictional Determination (PJD) has not yet been issued for this project, although a site
visit with the U.S. Army Corps of Engineers took place on September 8, 2023 to introduce the project and
stormwater treatment sites to the regulatory agencies. The PJD package is located in Attachment I.

Alternatives Analysis
The proposed project is located within the property limits of an existing airport which limits the alternative
options available. A Final Environmental Assessment (EA) was completed in September 2020. Within the
Final EA, an alternatives analysis was presented that compared two alternatives to the preferred alternative,
or proposed Midfield Development site (Attachment A). The Final EA did not assess the areas needed for
the submerged gravel wetland or borrow areas. The location of the proposed project within an active airport
requires it to adhere to FAA regulations regarding airfield operations. This limits the number of potential
sites that can meet FAA regulations, have sufficient space to house planned buildings, and have reasonable
access to the airfield.
Preliminary Alternative A
A 20-acre site located west of the existing hangars at the northern end of the Airport was designated as
Preliminary Alternative A and was considered in the EA. This site is on private property west of Swift
Creek Road and would require acquisition by the Airport. Additional property acquisition would also be
required for relocation of Swift Creek Road to the west of this site. Preliminary Alternative A is entirely
outside the Building Restriction Line (BRL) and Runway Protection Zones (RPZ) and provides a similar
area for hangar construction as the proposed alternative. Preliminary Alternative A was selected as a
potential alternative on the west side of the Airport that best avoided impacts to wetlands associated with
Reedy Branch to the north and Swift Creek to the south.
To provide access from Preliminary Alternative A to the airfield and to incorporate it inside the Airport's
security fence, it would require relocating approximately 0.9 miles of Swift Creek Road. The relocation of
Swift Creek Road would require filling approximately 2.1 acres of riparian wetlands, and 0.62 acres of
riparian buffer associated with Reedy Branch. In addition, Preliminary Alternative A would require full or
partial acquisition of land from 11 parcels including two residences and three businesses. It would have a
4

total cost of $36.1 million, nearly 30 percent higher than the proposed Midfield Development site. For all
of these reasons Alternative A was not selected.
Preliminary Alternative B
Preliminary Alternative B is located on the east side of the airfield, where more land is located on Airport
property but there are also larger wetland and floodplain concerns. Additionally, steep slopes averaging 18
to 23 percent from most of the airfield to the surrounding valley are present in this alternative and would
require extensive fill to provide a suitable area with an acceptable grade to the airfield. This site would
result in approximately 10.1 acres of wetlands impacts and 6.1 acres of fill in the floodplain. When
compared to the proposed Midfield Development site, this alternative would not significantly avoid or
minimize impacts to wetlands (approximately 10 acres of wetlands will be impacted by the proposed
Midfield Development site), floodplain, or the Neuse River riparian buffer. In addition, it is more remote
from Airport services such as the terminal and fueling. Hangars on this side of the airfield would require at
least a partial parallel taxiway to access one end of the runway. Otherwise, accessing these areas would
require aircraft to cross the runway to reach the existing parallel taxiway, or taxiing on the runway,
potentially causing frequent runway incursions. Runway incursions are a major safety hazard, which FAA
requires to be avoided or minimized. Development options on the east side of the runway are limited by the
BRL as well as the steep slopes. Taxiways, taxilanes, and aprons can be constructed inside the BRL, but
hangars cannot. Expanding this area to accommodate facilities proposed for the proposed project would
require the area chosen for Preliminary Alternative B which would provide 20 acres outside the BRL in
addition to an access driveway from US 70-BUS. For all these reasons, this alternative was not selected.
Alternatives Eliminated from Further Consideration
There are several sites near the south end of the Airport that are closer to the airfield than Alternative A;
however, construction on these sites would impact Swift Creek and were discarded. Development in this
southern area would also require substantial wetlands fill, and the relocation or crossing of Swift Creek.
Preferred Alternative (Proposed Midfield Development site)
The proposed Midfield Development site is located on the west side of the airfield on approximately 24-
acres located between existing corporate and general aviation hangars. The gated road from Swift Creek
Road that provides access to hangars at the south end of the Airport would be relocated slightly to the west
to accommodate the proposed project. Approximately 21 acres would be used for hangars, aprons, taxilanes,
and taxiways, and the remaining three acres would accommodate relocating the access road. The Airport
currently owns the undeveloped site, and it is well -integrated into the Airport facilities. This site was
selected because it meets FAA design requirements, eliminates impacts to Reedy Branch, and would not
require the acquisition of property. The site is enclosed within the Airport security fence and has easy access
to Airport services and facilities such as fueling, the Airport terminal, and the fixed base operator (FBO),
which are located north of the site. This site provides for safe and efficient aircraft operations.
Construction of the Midfield Development site will result in filling of 10.29 acres of wetlands and 397 feet
of intermittent stream. This site would not require the relocation of Swift Creek Road and its bridge over
Reedy Branch or the construction of a service road for access. It meets FAA requirements for development
and would not require the lengthy taxiing through existing hangar areas that Alternative A would require
or the construction of a new partial taxiway that Alternative B would require.
Stormwater Control Measure Alternatives Analysis
There were many constraints controlling the identification of an appropriate location for the placement of
a stormwater control measure (SCM) that would be sufficient in size to handle the increased runoff resulting
from the Midfield Development. Stormwater from the midfield area currently drains into a former
stormwater treatment facility located southeast of the airfield (Attachment A). This former stormwater

treatment facility is no longer maintained but is located in a natural topographic crenulation that would have
carried runoff from the entire midfield area and airfield prior to its construction and development.
The former stormwater treatment facility was placed so that it would filter runoff before making its way to
a natural wetland system to the south and east that then carries water east to Reedy Branch. Placement of
the former stormwater treatment facility was constrained by a wetland restoration mitigation site to the
north.
Retaining this stormwater drainage pattern was determined to be the least environmentally intrusive in that
the area was formerly used for stormwater retention and treatment and it provides a natural drainage
pathway that allows for filtration within the SCM as well as the adjacent wetlands before reaching Reedy
Branch. There are no other feasible locations for a SCM as placing it further north above the wetland
restoration mitigation site would require drainage to be pumped upslope and placing to the north of the
Midfield Development would not only require drainage to be pumped upslope but would also drain into
Swift Creek without a natural wetland buffer for further filtration.
Avoidance and Minimization
The proposed project includes two locations where stormwater runoff enters a riparian area. These include
the proposed submerged gravel wetland located on the southeast side of the runway and the proposed linear
dry pond and level spreader that would be located on the western edge of the Midfield Development. The
linear dry pond and level spreader would carry runoff to the north and west into the riparian buffer of Swift
Creek.
Both SCMs were sited in locations that would maintain existing drainage patterns. Microscale practices
(i.e. bioretention, wet swales, etc.) were considered but deemed infeasible due to the nature of the planned
site construction that will be composed of different construction packages and builders. It was determined
that employing SCMs at existing drainage outfalls allows for control of the stormwater from project
inception through project completion. Additionally, placement of the submerged gravel wetland over the
former stormwater treatment facility was more desirable than impacting a larger area of natural landscape
and wetlands had the submerged gravel wetland been placed elsewhere.
SCMs are being implemented as part of the proposed project to comply with post -construction stormwater
management regulations and requirements. The Midfield Development project is considered a low -density
project and as such, dispersed flow through vegetated areas and vegetated conveyances (grassed swales)
will be implemented to the greatest extent practical. These conveyances are designed to safely convey
runoff from the 10-year storm event as part of finalizing grading. Additional treatment is required by the
FAA with aircraft storage and maintenance areas in the form of glycol diversion vaults, oil/water diversion
vaults, and 5,000-gallon oil/water separators that will be implemented in two locations. The first location
will capture drainage from the midfield apron area and the second will capture drainage from the south
hangar area. These treatment facilities will provide protection to the proposed SCMs and other downstream
areas from the discharge of oil, grease, and other contaminants from aircraft and maintenance activities.
Runoff from the majority of the Midfield Development will be treated by the submerged gravel wetland,
an innovative SCM that is increasingly being used in NC and has promising pollutant removal abilities
when compared to standard NCDEQ approved primary SCMs. The submerged gravel wetland is not yet
approved as a Primary SCM in NC but is currently approved for use in other states, including New
Hampshire, New Jersey, and Maryland. Submerged gravel wetlands have shown a high degree of pollutant
removal and should provide equal treatment and be comparable to approved Primary SCMs such as wet
detention ponds and stormwater wetlands. Stormwater runoff for the Midfield Development will be directed
from Airport property and offsite drainage areas (168.53 acres total drainage area, 63.32 acres impervious
area) towards the proposed submerged gravel wetland via two 72-inch reinforced concrete pipes (RCP) into
a flow splitter at the downstream end of the 72-inch RCPs. The flow splitter will direct runoff from smaller
storms into the submerged gravel wetland forebay via low flow pipes and higher flows over an overflow

weir into a bypass channel. The submerged gravel wetland will have three cells filled with a gravel media
consisting of a 3-foot base layer of No. 57 stone (minimum is 1 foot) and 3 inches of No. 78 stone. A 6-
inch perforated underdrain is proposed at the downstream end of each cell and will maintain a permanent
water surface elevation 8 inches below the surface. The underground permanent water surface will facilitate
the growth of algae on the gravel surfaces and promote anaerobic processes for pollutant removal. The
perforated underdrains will connect to a solid underdrain pipe that will outfall into the natural conveyance
feature downstream. Underdrain cleanouts are proposed throughout the underdrain system.
Stormwater runoff at the smaller area at the western edge of the Midfield Development (4.16 acres total
drainage area, 2.94 acres impervious area) will be diverted to a linear dry pond and level spreader filter
strip for treatment prior to being dispersed through a vegetated filter strip upgradient of the 50-foot riparian
buffer for Swift Creek. The linear dry pond will receive flow from four inflow pipes and sheetflow from
the proposed hangar rooftops, paved access road, parking areas, and grassed/vegetated areas. No aircraft
runway or maintenance areas drain to this smaller treatment area. A 5-foot-wide pre-treatment gravel
curtain is proposed along the edge of pavement to collect fine sediment from the adjacent driveway before
entering the linear dry pond. The control structure for the linear dry pond will be a precast concrete endwall
with a 6-inch diameter orifice plate and trash rack which is connected to a 12-inch RCP that outlets to the
level spreader filter strip.
SCMs were selected and designed to avoid promoting standing water and attracting wildlife (a flight hazard)
as required by FAA regulations. Outlets from both facilities were designed to avoid erosion downslope of
the discharge point during the peak flow from a 10-year storm event. Rip -rap outfall protection will be
implemented in all outfalls (overflow spillways and pipe outfalls) leading to Swift Creek for additional
erosion protection. NCDEQ only requires quantity control of the 1-year storm event when comparing pre -
and post -development conditions; however, due to the sensitivity of the watershed, additional treatment
measures were designed. The submerged gravel wetland was designed to provide a decrease in discharge
up to the 10-year storm event and the linear dry pond was designed to provide a decrease in discharge up
to the 25-year storm event when comparing pre- and post -development conditions. Both facilities are
designed to contain the 100-year storm event with one foot of freeboard capacity, providing an additional
foot of quantity storage above the 100-year storm event.
Several erosion and sediment control measures will also be utilized during project construction to prevent
sediment laden runoff from entering downslope stream systems while the proposed project is being
constructed. Protective measures include prohibition of entry into the protected buffer along Swift Creek
which will be stated as such in the construction plans. Construction dewatering will be kept internal to the
area disturbed and will never drain in the direction of Swift Creek. Soil stockpiles will be placed in a manner
or protected so that there will be no drainage towards Swift Creek. Following completion of earth
disturbance, the ground will be stabilized immediately in areas that drain towards Swift Creek. This is a
more stringent requirement than the NC requirement of stabilization to occur within 7 days of stopping
work. Super silt fence will also be installed along the limits of disturbance outside the buffer instead of
standard silt fencing as an enhanced protection measure. Super silt fence is stronger than standard silt fence
and utilizes a combination of chain link fence, metal posts, and woven polypropylene material and is a more
appropriate sediment fencing option for sensitive locations, being able to handle larger amounts of erosion
and remain effective at the bottom of slopes. All erosion and sediment control measures protecting Swift
Creek will be inspected daily to ensure proper function for the full duration of construction activities
upslope of Swift Creek.
The measures utilized for stormwater management and erosion and sediment control during construction
for the proposed project were designed to maximize the treatment of stormwater runoff and reduce sediment
entering the Critical Habitat area of Swift Creek. The SCM facility types selected provide significant
reductions in sediment within stormwater runoff from the watershed prior to discharge into the receiving
streams, Reedy Branch and Swift Creek. Additionally, the proposed SCMs were selected to discourage
wildlife activity per FAA regulations. Drainage and associated stormwater management systems are to

adhere to recommendations contained in FAA Advisory Circular 150/5200-33C, Hazardous Wildlife
Attractants on or near Airports. Stormwater management systems should be designed and operated to
prevent creation of above -ground standing water with a maximum 48-hour detention period after the design
storm. The proposed submerged gravel wetland is designed to manage and treat stormwater runoff without
vegetation or an above ground permanent pool to avoid attracting waterfowl which pose a strike hazard to
aircraft. Similarly, the linear dry pond and level spreader are designed to manage and treat stormwater
runoff and remove sediment while maintaining no permanent standing water. Other SCM facility types
including wetlands, wet ponds, and filtering systems may attract wildlife due to permanent standing water
and vegetation. Physical barriers such as bird balls, wire grids, floating covers, vegetation barriers (bottom
liners), or netting can be installed to deter waterfowl and other hazardous wildlife on these open systems
but such measures typically require some sort of annual maintenance and are not preferable.
The proposed drainage layouts discussed were designed to match existing drainage patterns and drainage
areas; in addition, ditches and associated drainage structures were placed so that they would be outside of
aircraft operational runway and taxiway safety areas to adhere to FAA Advisory Circular 150/5300-13B,
Airport Design and Advisory Circular 150/5320-5D, Airport Drainage Design and provide for the
maximum allowable development area to meet current hangar demands.
Mitigation
Wetland, stream, and riparian buffer mitigation will be required for the proposed project. A ratio of 2:1
mitigation credits will be implemented by the U.S. Army Corps of Engineers for wetland and stream
impacts in areas that score medium to high on NC Wetland Assessment Method (NCWAM) and NC Stream
Assessment Method (NCSAM) rating forms. Features scoring Low receive a 1:1 mitigation credit
requirement ratio. 37.14 acres of wetland mitigation credits and 1,816.7 linear feet of stream mitigation
credits will be needed to mitigate impacts to Waters of the U.S. associated with the proposed project.
Riparian buffer mitigation will also be required at a 3:1 ratio for Zone 1 impacts and 1.5:1 ratio for Zone 2
impacts since the proposed project lies in the Neuse 03020201 HUC and Neuse River Riparian Buffer
Protection Rules apply in this watershed. The Airport will be purchasing wetland and stream mitigation
credits from two mitigation bankers (RES Inc., and Clearwater Mitigation Solutions) as well as the NC
Division of Mitigation Services (NCDMS) as none of the private mitigation banks in the watershed have
enough wetland credits to fulfill the entire amount required by the proposed project. The final credit amount
to come from each source will be determined once the permit is approved and payments are made.
Statements of Availability from the mitigation bankers and a NCDMS in -lieu fee request form are included
in Attachment C.
Essential Fish Habitat (EFH)
The proposed project does not occur in one of the eighteen coastal counties in which waterbodies containing
EFH species are found (Beaufort, Bertie, Brunswick, Camden, Carteret, Chowan, Craven, Currituck, Dare,
Hyde, New Hanover, Onslow, Pamlico, Pasquotank, Pender, Perquimans, Tyrrell, and Washington). A
National Oceanic and Atmospheric Administration (NOAA) - National Marine Fisheries Service (NMFS)
database search using the EFH Mapper was also conducted to identify any federally listed EFH that may
potentially occur within or near the proposed project. There is also no EFH identified within or near the
project area.
Hydrology & Hydraulics
The project area crosses part of the Federal Emergency Management Administration (FEMA) designated
Zone AE Special Flood Hazard Area (SFHA) for a backwater tributary of Reedy Branch (AE). The SFHA
is defined by FEMA as the area that will be inundated by the flood event having a one percent chance of
being equaled or exceeded in any given year. The one percent annual chance flood is also referred to as the

base flood or 100-year flood. A figure showing the extent of the SFHA is included in Attachment D.
Additionally, a portion of the 0.2% Annual Chance Flood Hazard Area as depicted in FEMA FIRM
3720168500K, (Effective Date 6/20/2018) associated with the same backwater is also crossed by the project
area.
According to FAA Order 1050.1E, Change 1, floodplain impacts are considered significant pursuant to
NEPA if they result in notable adverse impacts on natural and beneficial floodplain values. Furthermore, a
significant encroachment is an encroachment resulting in one or more of the following construction or flood
related impacts: (1) a considerable probability of loss of human life; (2) likely future damage associated
with the encroachment that could be substantial in cost or extent, including interruption of service on or
loss of a vital transportation facility; and (3) a notable adverse impact on "natural and beneficial floodplain
values."
The proposed project will not result in changes to the volumetric capacity of the floodplain or indirectly
through an increase in the total volume of water arriving at and being conveyed by the floodplain, thus, no
impacts are expected and there would be no notable adverse effect on natural and beneficial floodplain
values.
Threatened and Endangered Species
The U.S. Fish and Wildlife Service (USFWS) iPaC online resource tool generated a list of eight federally
listed species that could be impacted by the proposed project. These species are listed in Table 4 along with
their protection status. A review of the NC Natural Heritage Program (NCNHP) Geographic Database of
Rare and Endangered Species dated July 5, 2023, shows a very old, historic occurrence (1833) of Michaux's
sumac (Rhus michauxii) documented within 2 miles of the project area and a more current occurrence
(2005) of red -cockaded woodpecker documented within 5 miles of the project area. The red -cockaded
woodpecker occurrence is from a colony that is no longer present and was last observed in 2005. The
woodpecker site has been documented as having been clear-cut in 2017.
AECOM biologists performed a Threatened and Endangered Species Habitat Assessment of the project
area on January 5, 2023 and May 9, 2023. Wet pine flatwoods (primarily loblolly pine) are present to the
general north and south of the former stormwater treatment facility. These were surveyed for the presence
of red -cockaded woodpecker nest trees and no nest trees or nest starts were observed during field
investigations. Suitable foraging and roosting habitat for tri-colored bat is located in the project area,
although this bat is currently listed as Proposed Endangered and currently does not afford protection under
the Endangered Species Act.
Swift Creek is located to the northwest and immediately adjacent to the Midfield Development and is listed
as Critical Habitat for four aquatic species; Neuse River waterdog, Carolina madtom, yellow lance, and
Atlantic pigtoe (Attachment E). It is also known habitat for dwarf wedgemussel. Aquatic habitats within
the project area are much smaller and more degraded. There is a small first order perennial stream (S1/S3)
present within the project area that is a combination of a small flowing stream and backwater inundation
upstream of the former stormwater treatment facility and a small flowing stream again downstream of the
former stormwater treatment facility. It is approximately 2 feet wide where it is flowing between the
runway and taxiway and 5 feet wide just upstream of the former stormwater treatment facility. The stream
has been channelized upstream of the former stormwater treatment facility and consists of a heavily
sedimented reach that is situated between a culvert under the runway and the former stormwater treatment
facility. Downstream of the former stormwater treatment facility, the stream exits through an active beaver
dam and is very small (2-4 feet wide) and flows approximately 400 feet before the stream channel
disappears and it dissipates into a hardwood swamp. Downstream of the former stormwater treatment
facility it has a silt/sand substrate and relatively clear water appearing more natural in character. The small
size of the downstream reach and heavily modified nature of the upstream reach rule out its suitability as

habitat for Neuse River waterdog, Carolina madtom, and Atlantic pigtoe. The isolated nature of the project
reaches and modified nature of large portions of the stream in the project area make it unlikely that dwarf
wedgemussel or yellow lance are present either.

The purpose of this letter is to notify you that the NCDEQ Division of Mitigation Services (DMS) is willing to
accept payment for compensatory mitigation for impacts associated with the above referenced project as
indicated in the table below. Please note that this decision does not assure that participation in the DMS in -
lieu fee mitigation program will be approved by the permit issuing agencies as mitigation for project impacts.
It is the responsibility of the applicant to contact permitting agencies to determine if payment to the DMS will
be approved. You must also comply with all other state, federal or local government permits, regulations or
authorizations associated with the proposed activity including G.S. § 143-214.11.
This acceptance is valid for six months from the date of this letter and is not transferable. If we have not
received a copy of the applicable 404 Permit/401 Certification/Buffer Approval within this time frame,
this acceptance will expire. It is the applicant's responsibility to send copies of the permits to DMS. Once
DMS receives a copy of the permit(s) an invoice will be issued based on the required mitigation in that permit
and payment must be made prior to conducting the authorized work. The amount of the in -lieu fee to be paid
by an applicant is calculated based upon the Fee Schedule and policies listed on the DMS website.
Based on the information supplied by you in your request to use the DMS, the impacts for which you are
requesting compensatory mitigation credit are summarized in the following table. The amount of mitigation
required and assigned to DMS for this impact is determined by permitting agencies and may exceed the
impact amounts shown below.

Dear Kevin Lapp.
D. Reid Wilson, Secretary
Misty Buchanan
Deputy Director, Natural Heritage Program
NCNHDE-24174
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached `Documented Occurrences' tables and map.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is documented within the project area or indicated within a one -mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund
easement, or an occurrence of a Federally -listed species is documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact the NCNHP at natural.heritaaeWdncr.nc.aov.
Sincerely,
NC Natural Heritage Program

Location description: The Johnston County Airport is located at 3149 Swift Creek Road. It is bounded by Swift Creek Road on
the west, Swift Creek on the south, and US 70 Business on the north. Undeveloped forest, swamp, and agricultural lands occur
on its east. The proiect area for the mid -airfield development proiect is situated in a forested area between an existing
maintenance road, Swift Creek Road, existing on -site hangars, and the airfield's runway.
Indicate Which of the Following Apply:
A. Preliminary Determination
® There appear to be waters, including wetlands on the above described project area/property, that may be subject to
Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33
USC § 403). The waters, including wetlands have been delineated, and the delineation has been verified by the Corps to be
sufficiently accurate and reliable. The approximate boundaries of these waters are shown on the enclosed delineation map
dated April 2020. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process,
including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation
requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat
all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional
waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program
Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an
appealable action, by contacting the Corps district for further instruction.
❑ There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404
of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403).
However, since the waters, including wetlands have not been properly delineated, this preliminary jurisdiction determination
may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is
merely an effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands at the project area, which
is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters,
including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland
delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps.
B. Approved Determination
❑ There are Navigable Waters of the United States within the above described project area/property subject to the permit
requirements of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act
(CWA)(33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for
a period not to exceed five years from the date of this notification.
❑ There are waters, including wetlandson the above described project area/property subject to the permit requirements of Section
404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published regulations, this
determination may be relied upon for a period not to exceed five years from the date of this notification.

❑ We recommend you have the waters, including wetlands on your project area/property delineated. As the Corps may not be
able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that
can be verified by the Corps.
❑ The waters, including wetlands on your project area/property have been delineated and the delineation has been verified by
the Corps. The approximate boundaries of these waters are shown on the enclosed delineation map dated DATE. We strongly
suggest you have this delineation surveyed. Upon completion, this survey should be reviewed and verified by the Corps. Once
verified, this survey will provide an accurate depiction of all areas subject to CWA jurisdiction on your property which, provided
there is no change in the law or our published regulations, may be relied upon for a period not to exceed five years.
❑ The waters, including wetlands have been delineated and surveyed and are accurately depicted on the plat signed by the
Corps Regulatory Official identified below onDATE. Unless there is a change in the law or our published regulations, this
determination may be relied upon for a period not to exceed five years from the date of this notification.
❑ There are no waters of the U.S., to include wetlands, present on the above described project area/property which are subject to the
permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published
regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification.
❑ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA).
You should contact the Division of Coastal Management in Morehead City, NC, at [phone] to determine their
requirements.
Placement of dredged or fill material within waters of the US, including wetlands, without a Department of the Army permit may
constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material, construction or
placement of structures, or work within navigable waters of the United States without a Department of the Army permit may
constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403). If you have any questions
regarding this determination and/or the Corps regulatory program, please contact Christopher Hopper at [phone] (x35) or
christopher.d.hopper(a,usace.army.mil.
C. Basis For Determination: Basis For Determination: See the preliminary iurisdictional determination
form dated 06/15/2020, and the attached exhibit, "Figure 4: Approximate Waters of the U.S. Map,
JNX Mid -Airfield Development Proposed Proiect Site".
D. Remarks: None.
E. Attention USDA Program Participants
This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the particular site
identified in this request. The delineation/determination may not be valid for the wetland conservation provisions of the Food Security
Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation in USDA programs, you should request
a certified wetland determination from the local office of the Natural Resources Conservation Service, prior to starting work.

1. The Corps of Engineers believes that there may be jurisdictional aquatic resources in the
review area, and the requestor of this PJD is hereby advised of his or her option to request
and obtain an approved JD (AJD) for that review area based on an informed decision after
having discussed the various types of JDs and their characteristics and circumstances when
they may be appropriate.
2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide
General Permit (NWP) or other general permit verification requiring "pre- construction
notification" (PCN), or requests verification for a non -reporting NWP or other general
permit, and the permit applicant has not requested an AJD for the activity, the permit
applicant is hereby made aware that: (1) the permit applicant has elected to seek a permit
authorization based on a PJD, which does not make an official determination of
jurisdictional aquatic resources; (2) the applicant has the option to request an AJD before
accepting the terms and conditions of the permit authorization, and that basing a permit
authorization on an AJD could possibly result in less compensatory mitigation being
required or different special conditions; (3) the applicant has the right to request an
individual permit rather than accepting the terms and conditions of the NWP or other
general permit authorization; (4) the applicant can accept a permit authorization and
thereby agree to comply with all the terms and conditions of that permit, including
whatever mitigation requirements the Corps has determined to be necessary; (5)
undertaking any activity in reliance upon the subject permit authorization without
requesting an AID constitutes the applicant's acceptance of the use of the PJD; (6)
accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking
any activity in reliance on any form of Corps permit authorization based on a PJD
constitutes agreement that all aquatic resources in the review area affected in any way by
that activity will be treated as jurisdictional, and waives any challenge to such jurisdiction
in any administrative or judicial compliance or enforcement action, or in any administrative
appeal or in any Federal court; and (7) whether the applicant elects to use either an AJD or
a PJD, the JD will be processed as soon as practicable. Further, an AJD, a proffered
individual permit (and all terms and conditions contained therein), or individual permit
denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an
administrative appeal, it becomes appropriate to make an official determination whether
geographic jurisdiction exists over aquatic resources in the review area, or to provide an
official delineation of jurisdictional aquatic resources in the review area, the Corps will
provide an AID to accomplish that result, as soon as is practicable. This PJD finds that
there "may be" waters of the U.S. and/or that there "may be" navigable waters of the U.S.
on the subject review area, and identifies all aquatic features in the review area that could
be affected by the proposed activity, based on the following information:

Re: Request for Preliminary Jurisdictional Determination
Midfield Apron Development
Johnston Regional Airport (JNX)
Johnston County
Dear Mr. Hopper:
5438 Wade Park Blvd, Suite 200
Raleigh, NC 27607
www.aecom.com
Johnston Regional Airport (JNX) is submitting a request for a Preliminary Jurisdictional
Determination for the unreviewed areas associated with the midfield apron development
in Johnston County, North Carolina. The project is located on both sides of the
taxiway/runway and encompasses an area of 62.7 acres in addition to the 23.7-acre
midfield apron development area that was previously reviewed under a Preliminary
Jurisdictional Determination on June 15, 2020 (SAW 2001-20723). The study area
consists of numerous small areas surrounding the original Midfield apron site in addition
to a large portion of the grassed area between the taxiway and runway and the detention
pond southeast of the runway and adjacent forest.
Potential jurisdictional waters were delineated over a period of approximately 7 months
by AECOM between September 20, 2022 and May 9, 2023 as design evolution brought
in additional areas to be investigated. Within the project area, three perennial streams
were identified along with four potential wetlands.
Enclosed for your review and approval is a Preliminary Jurisdictional Determination
request form with supporting figures and documentation. Please contact me at 919-
602-7505 or [e-mail] to schedule a site visit or if you should have any
questions regarding the enclosed information.
Sincerely,
Kevin Lapp

Jurisdictional Determination Request
F. JURISDICTIONAL DETERNIINATION (JD) TYPE (Select One)
7 I am requesting that the Corps provide a preliminM JD for the property identified herein.
A Preliminary Jurisdictional Determination (PJD) provides an indication that there may
be "waters of the United States" or "navigable waters of the United States"on a property.
PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all
waters and wetlands on the property will be treated as if they are jurisdictional "waters of
the United States". PJDs cannot be appealed (33 C.F.R. 331.2); however, a PJD is
"preliminary" in the sense that an approved JD can be requested at any time. PJDs do
not expire.
❑ I am requesting that the Corps provide an approved JD for the property identified herein.
An Approved Jurisdictional Determination (AJD) is a determination that
jurisdictional "waters of the United States" or "navigable waters of the United
States" are either present or absent on a site. An approved JD identifies the limits of
waters on a site determined to be jurisdictional under the Clean Water Act and/or
Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit
decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be
posted on the Corps website. A landowner, permit applicant, or other "affected
party" (33 C.F.R. 331.2) who receives an AJD may rely upon the AJD for five years
(subject to certain limited exceptions explained in Regulatory Guidance Letter 05-
02).
❑ I am unclear as to which JD I would like to request and require additional information
to inform my decision.
G. ALL REQUESTS

1. The Corps of Engineers believes that there may be jurisdictional waters of the
United States on the subject site, and the permit applicant or other affected party
who requested this preliminary JD is hereby advised of his or her option to
request and obtain an approved jurisdictional determination (JD) for that site.
Nevertheless, the permit applicant or other person who requested this
preliminary JD has declined to exercise the option to obtain an approved JD in
this instance and at this time.
2. In any circumstance where a permit applicant obtains an individual permit, or
a Nationwide General Permit (NWP) or other general permit verification requiring
"pre -construction notification" (PCN), or requests verification for a non -reporting
NWP or other general permit, and the permit applicant has not requested an
approved JD for the activity, the permit applicant is hereby made aware of the
following: (1) the permit applicant has elected to seek a permit authorization
based on a preliminary JD, which does not make an official determination of
jurisdictional waters; (2) that the applicant has the option to request an approved
JD before accepting the terms and conditions of the permit authorization, and
that basing a permit authorization on an approved JD could possibly result in less
compensatory mitigation being required or different special conditions; (3) that
the applicant has the right to request an individual permit rather than accepting
the terms and conditions of the NWP or other general permit authorization; (4)
that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking
any activity in reliance upon the subject permit authorization without requesting
an approved JD constitutes the applicant's acceptance of the use of the
preliminary JD, but that either form of JD will be processed as soon as is
practicable; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a preliminary JD constitutes agreement that all
wetlands and other water bodies on the site affected in any way by that activity
are jurisdictional waters of the United States, and precludes any challenge to
such jurisdiction in any administrative or judicial compliance or enforcement
action, or in any administrative appeal or in any Federal court; and (7) whether
the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable. Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual
permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331,
and that in any administrative appeal, jurisdictional issues can be raised (see 33
C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary
to make an official determination whether CWA jurisdiction exists over a site, or
to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable.

This preliminary JD finds that there "may be" waters of the United States on the
subject project site, and identifies all aquatic features on the site that could be
affected by the proposed activity, based on the following information:
