b. Give a brief description of purpose. use, and daily operations of the project when complete.
The purpose of the proposed project is to meet FAA requirements by mitigating public safety hazards associated with aircraft
travel by preventing human and wildlife access within the airfield at the project location to improve aircraft safety. The
proposed project will address excessive erosion within the stream feature (Stream 1) resulting from extraordinary rainfall and
flooding from Hurricane Florence which destabilized the channel. Stream 1 is the outlet for the stormwater drainage system
for approximately 37-acres within the airport. The erosion within the channel continues to get worse with each heavy rainfall
event and has eroded out a large area underneath the perimeter security fence. The erosion continues to widen the channel
at the perimeter security fence, resulting in the airport maintenance regularly having to block the new holes under the fence
with metal rods. The metal rods then catch debris, which causes the stream to erode around the metal posts, creating a
constant maintenance issue. The frequent undermining of the perimeter security fence poses a significant security risk, as
the erosion creates access points into the airfield for both humans and wildlife at the Runway 6 approach. The erosion and
sedimentation have also created conditions within the channel that is attracting wildlife. These conditions create a safety
issue as Stream 1 is within the Runway 6 Approach and approximately 800 If from the end of Runway 6, greatly increasing
the likelihood of a wildlife strike with an aircraft. In 2018, a small passenger aircraft struck a coyote on the runway, and the
proposed project is critical to improving aircraft and public safety.
Additionally, the head cut from the erosion has progressed approximately 300 If upstream from the perimeter security fence to
the perimeter road culvert in approximately 1 &months. If not addressed, the erosion will undercut the perimeter road culvert
and continue upstream, threatening the integrity of Runway 6. Since the initial damage to the stream channel and ensuing
erosion resulted from flooding from Hurricane Florence, the proposed project is being funded by FEMA. FEMA prepared a
Record of Environmental Consideration (REC) in accordance with NEPA, which determined that the proposed project met
conditions for authorization under a CATEX category *N9 — Federal Assistance for Flood Hazard Reduction Actions. The
FEMA REC has been provided as an attachment.
The proposed project proposes to permanently impact Stream 1, of which approximate 72 If is tidal and 244 If is non -tidal. The
project proposes to grade the slopes of the channel and surrounding areas to a 3:1 slope and line the entire channel with an
articulating concrete block geogrid system and riprap which will permanently stabilize the channel and prevent future erosion
and undermining of the perimeter security fence, permanently eliminating the reoccurring safety issue at this location. The
articulating concrete block liner is pervious, allowing water to infiltrate through it, as well as vegetation to grow up through it
and has been used to successfully stabilize other onsite stormwater swales at ILM (see Photo Documentation).
the stream channel will be lined from the existing perimeter road culvert to an existing culvert approximately 30 It southwest of
the existing security fence. This culvert is located within the CFPUA sewer maintenance access road. The articulating block
will be installed within the stream from the perimeter road culvert to the security fence, with the section of stream from the
security fence to the downstream culvert lined with riprap to dissipate flow, stabilize the channel, and protect the culvert from
erosion and undercutting. A concrete headwall will be constructed on the upstream end of the existing culvert to provide
permanent stabilization and protection of the culvert. Additionally, a concrete headwall will be constructed on the
downstream end of the perimeter road culvert.
the perimeter security fence will be temporarily relocated over the existing culvert to the southwest during construction but will
be reconstructed in its current location once construction is complete. Metal bars will be installed extending from the bottom
of the fence through the channel to provide prevent access under the fence by wildlife or humans. The metal bars will be
installed approximately 4" apart and will be anchored in a 12" long x 12" wide x 12" high concrete beam that will be installed
below ground directly below the fence (see Figure 3 in Impact Maps).
portion of Stream 1 inside of the perimeter security fence is an inland -tidal stream. However, per previous NCDCM
determinations on similar projects at the Wilmington International Airport, CAMA jurisdiction stops at the existing security
fence as the portions upstream of the perimeter security fence are not navigable. Therefore, the tidal portions of Stream 1
upstream of the security fence are considered Section 404/10 waters but are not subject to CAMA jurisdiction. The portion of
Stream 1 downstream of the security fence is considered navigable waters subject to CAMA jurisdiction.
'he completion of the project will increase aircraft and public safety as part of the normal daily operation and activities
associated with the operation of the airport. Please note that the proposed project will not create any additional impervious
area and will not change the existing volume of stormwater drainage discharging into downstream portions of Stream 1.
:. Describe the proposed construction methodology, types of construction equipment to be used during construction, the number of each type
of equipment and where it is to be stored.
Standard commercial construction equipment of various sizes and number will be used to construct the proposed project
(see Project Narrative for more information). All equipment will be stored outside of the AEC in uplands adjacent to the
project.
d. List all development activities you propose.
Grading of stream banks and adjacent areas to create a 3:1 slope, installing an articulating concrete block geogrid and riprap
within Stream 1 to permanently stabilize the channel and permanently eliminate erosion, construction of a headwall on the
upstream end of the CFPUA sewer maintenance road culvert and construction of a headwall on the downstream end of the
perimeter road culvert.
e. Are the proposed activities maintenance of an existing project, new work, or both? new work

May 24, 2021
This letter is in reference to the application submitted for the New Hanover County Airport
Authority, for a Coastal Area Management Act Major Permit to undertake development activities
to stabilize a jurisdictional ditch, in New Hanover County.
Although processing of the application is nearing completion, additional time is needed for this
office to complete the review and make a decision on your request. Therefore, it is necessary that
the standard review time be extended. An additional 75 days is provided by G.S. 113A-122(c)
which would make August 5, 2021 the new deadline for reaching a decision on your request.
However, we expect to take action prior to that time and will do so as soon as possible. In the
interim, should you have any question on the status of your application, do not hesitate to contact
me by phone [phone] ext. 215) or e-mail ([e-mail]).

Recommendations for State Permit -New Hanover County Airport Authority 3/16/2021
The proposed stabilization project would stop the current erosion in the project area stream within the runway 6 area of the
Wilmington International Airport. The stabilization would facilitate public safety by reducing potential wildlife strikes and securing
the perimeter fence. It appears that the project is consistent with the use standards set forth in NCAC 07H .0208 (b) (4)
Nonagricultural Drainage, such that "Drainage ditches shall not create stagnant water pools or changes in the velocity of flow."
It appears that this project is also consistent with the management objectives for Coastal Wetlands NCAC 07H .0208 (b)(11)
Filling of Canals, Basins and Ditches, such that 'the filling will not adversely impact any designated primary nursery area,
shellfish bed, submerged aquatic vegetation as defined by the MFC, coastal wetlands, public trust right or public trust usage;..."

you must notify the Division and you may be required to submit a new application package with the
appropriate fee. If the property is sold, the new owner must be given a copy of this Certification and is
responsible for complying with all conditions. [35A NCAC 02H..0507(d)(2)].
If you are unable to comply with any of the conditions of the attached Water Quality General
Certification or with the additional conditions itemized below, you must notify the Wilmington Regional
Office within 24 hours (or the next business day if a weekend or holiday) from the time the permittee
becomes aware of the circumstances.
The permittee shall report to the Wilmington Regional Office any noncompliance with, and/or any
violation of, stream or wetland standards [15A NCAC 02B .0200] including but not limited to sediment
impacts to streams or wetlands. Information shall be provided orally within 24 hours (or the next
business day if a weekend or holiday) from the time the permittee became aware of the non-compliance
circumstances.
Additional Conditions:
1. No drill slurry or water that has been in contact with uncured concrete shall be allowed to enter
surface waters. This water shall be captured, treated, and disposed of properly. [35A NCAC 02H
.0506(b)(3)
2. At the location where the ditch will be dewatered, proper measures will betaken to drain the
ditch with limited impact to upstream and downstream channel stability. Proper measures will
be taken to avoid sediment release and/or sediment accumulation downstream as a result of
ditch dewatering. [15A NCAC 02H.0506(b)(2)]
General Conditions
1. Unless otherwise approved in this certification, placement of culverts and other structures in open
waters and streams shall be placed below the elevation of the streambed by one foot for all
culverts with a diameter greater than 48 inches, and 20 percent of the culvert diameter for
culverts having a diameter less than 48 inches, to allow low flow passage of water and aquatic life.
Design and placement of culverts and other structures including temporary erosion control
measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands or
streambeds or banks, adjacent to or upstream and downstream of the above structures. The
applicant is required to provide evidence that the equilibrium is being maintained if requested in
writing by NCDWR. If this condition is unable to be met due to bedrock or other limiting features
encountered during construction, please contact NCDWR for guidance on how to proceed and to
determine whether or not a permit modification will be required. [15A NCAC 02H.0506(b)(2)]
2. If concrete is used during construction, a dry work area shall be maintained to prevent direct
contact between curing concrete and stream water. Water that inadvertently contacts uncured
concrete shall not be discharged to surface waters due to the potential for elevated pH and
possible aquatic life and fish kills. [15A NCAC 02B.0200]
3. During the construction of the project, no staging of equipment of any kind is permitted in
waters of the U.S. or protected riparian buffers. [15A NCAC 021-1.0506WCEI QED

modified. Disturbed floodplains and streams shall be restored to natural geomorphic
conditions. [15A NCAC 02H.0506(b)(2)]
S. The use of rip -rap above the Normal High Water Mark shall be minimized. Any rip -rap placed
for stream stabilization shall be placed in stream channels in such a manner that it does not
impede aquatic life passage. [15A NCAC 02H.0506(b)(2)]
6. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit
drawings submitted for approval. [15A NCAC 02H .0507 (c) and 15A NCAC 02H .0506 (b)(2) and
(c)(2)l
7. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP
measures from the most current version of NCDOT Construction and Maintenance Activities
manual such as sandbags, rock berms, cofferdams and other diversion structures shall be used
to prevent excavation in flowing water. [15A NCAC 02H.0506(b)(3) and (c)(3)]
8. Heavy equipment shall be operated from the banks rather than in the stream channel in order
to minimize sedimentation and reduce the introduction of other pollutants into the stream.
[15A NCAC 02H.0506(b)(3)]
9. All mechanized equipment operated near surface waters must be regularly inspected and
maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or
other toxic materials. [15A NCAC 02H.0506(b)(3)]
10. No rock, sand or other materials shall be dredged from the stream channel except where authorized
by this certification. [15A NCAC 02H.0506(b)(3)]
11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent
to surface waters is prohibited. [15A NCAC 02H.0506(b)(3)]
12. All sediment and erosion control devices shall be removed and the natural grade restored within
two (2) months of the date that the Division of Energy, Mining and Land Resources (DEMLR) or
locally delegated program has released the specific area within the project. [15A NCAC
02H.0506(b)(3) and (c)(3)]
13. The permittee and its authorized agents shall conduct its activities in a manner consistent with State
water quality standards (including any requirements resulting from compliance with §303(d) of the
Clean Water Act) and any other appropriate requirements of State and Federal law. If the NCDWR
determines that such standards or laws are not being met (including the failure to sustain a
designated or achieved use) or that State or federal law is being violated, or that further conditions
are necessary to assure compliance, the NCDWR may reevaluate and modify this certification. [15A

Good morning Curt,
The Corps, myself and the consultant have had lengthy conversations about this project. The Corps and I agree that the
non-CAMA feature is not a stream but a jurisdictional ditch. The consultant is revising the application and should be
sending it in this morning. You should be copied on it as well. I hope to get it out today or tomorrow by the latest.
Hope all is well with you.

Hey Joanne,
It's good to be working on a project with you again, hope all is well. I know this project still has some time on it for
review, I just wanted to make sure that I was going to receive comments from you on this project. Usually Stephen Lane
or Greg Daisey tackle the transportation projects, but since this isn't a DOT issue, I'm the permit coordinator. Let me
know what would be best for you in terms of making sure that I don't miss any comments or input from your agency.

Greg/Joanne,
Based on my conversations with both of you today, the tributary proposed for impact will be considered a jurisdictional
ditch, rather than a stream and compensatory mitigation will not be required. For clarity of the file, I will prepare a
revised 404/401 PCN form (2020 version) that lists the impacts as "Ditch" impacts in Section 4 - Open Water Impacts. I'll
include a cover letter explaining the revisions and that mitigation is not proposed.
I'll do my best to get this to you this afternoon, but tomorrow at the latest.
Thanks for everyone's help!

Joanne, the Corps can approve this under PGP-291 since part of the feature is tidally influenced.
Furthermore, as far as mitigation proposed, after reviewing aerials of the stream, the Corps believes that although this
stream is a jurisdictional tributary, it is considered a jurisdictional ditch and not a stream. Therefore, the Corps is not
going to require mitigation for this stream.
Let me know if you have any questions.

Troy,
The updated Mitigation reservation letter is much appreciated. The DWR has no issues with the project and
understands the airports reason for wanting not to pipe the stream to allow for stormwater storage during storm
events. I am just waiting for the USACE to let me know how they plan on permitting it.

MEMORANDUM
To: Gregg Bodner
From: Michael Christenbury, Wilmington District Planner
Subject: Major Permit Application, Wilmington Airport Authority, New Hanover County
Date: May 18, 2021
This project is consistent and not in conflict with the New Hanover County Comprehensive
Land Use Plan.
The applicant proposes to grade eroding stream banks, line the channel with an articulating
concrete block system and rip rap and improve the perimeter fence adjacent to the Wilmington
International Airport (ILM) in Wilmington, New Hanover County.
I have reviewed this proposal for consistency with the 2016 New Hanover County
Comprehensive Land Use Plan and offer the following comments.
The general area of the project is classified as Airport Industrial District.
In general, New Hanover County allows development in Airport Industrial District classified
AECs, which is consistent with the State's minimum use standards. The New Hanover County
Comprehensive Land Use Plan contains some policies, which exceed the State's minimum use
standards. However, none of these policies appear to be applicable to this project.
This project appears is consistent with the 2016 New Hanover County Comprehensive
Land Use Plan.

9. PROJECT DESCRIPTION:
The Wilmington Intemational Airport is located at 1740 Airport Boulevard Road (off North 23rd Street) in Wilmington, New
Hanover County and is adjacent to Smith Creek. To locate the project site from NC Highway 17, travel north on North 23rd
Street for approximately 2 miles to the intersection of Airport Boulevard. Turn right onto Airport Boulevard, Access to the
project site is restricted due to FAA security regulations and can be accessed by escort from the AirportAuthority staff. You
may contact the airport Facilities Director Dick Granseur (910) 3414333 at the Wilmington Intemational Airport to schedule
a site visit
The Wilmington Intemational Airport consists of an airport terminal, parking, hangars, runways, roadways, approach lighting
systems including catwalk and light bars, and associated facilities. The Wilmington International Airport is located on a
large tracttotaling 1,340 acres and is a mix of wetlands and uplands with an average elevation of 7 feetabove Normal High
Water (NHW). The adjacent properties surrounding the project site are a mix of undeveloped uplands, commercial and
residential properties. The project site is located within the active airfield, which is maintained/mowed regularly to manage
vegetation at very low heights as required by the FAA.
The project area is located within the 1,340 acre Wilmington Intemational Airport, specifically the drainage area located in
the active airfield adjacent to the Runway Safety Area (RSA) of Runway 6 (See Figure 1). The project area includes
approximately 316' of unnamed tributary (UT) or Stream 1 that drains to inland waters of Smith Creek. The 316' of Stream
1 runs from the culvert under the perimeter road to the next culvert located under the CFPUA sewer maintenance access
road on the outside of the perimeter fence. The proposed stream impacts can be separated by jurisdictional and non -
jurisdictional impacts. The Public Trustiurisdictional area consists of 41 linear feetof navigable tidally influenced stream. A
perimeter fence exists, above which the stream is no longer considered navigable, and therefore the 30' Public TrustArea
of Environmental Concern (AEC) extends upstream of the perimeter fence. There is 31 linear feet of stream within the 30
ft. Public Trust Shoreline AEC for a total of 72' of jurisdictional stream in this area. The non -jurisdictional project area
extends from the end of the AEC, 244' upstream to the culvert under the perimeter road (see Figure 2). According to the
applicant, the project area receives water from historically channelized stormwater conveyances draining an area that is
approximately 37 acres. Vegetation inside the perimeter fence is primarily upland grasses and is consistently maintained
per FAA requirements. Vegetation on the outside of the fence consists of typical disturbed upland shrub / scrub species,
such as wax myrtle, pines, and small bays. Based on the site visit performed by Patrick Amico and Robb Mairs on
6/23/2020 no Coastal Wetlands are in the project area. Coastal Wetland species were noted downstream of the project
area closer to Smith Creek. Two sanitary sewer force mains traverse the project area. The 24" fora main traverses the
project area in the vicinity of the perimeter fence approximately 2' underthe proposed finish grade. The second force main
is 30" in diameter and crosses the project area outside of the perimeter fence approximately 6' below grade (see Figure 4).
Stream 1 is considered to have a low functional value according to North Carolina Stream Assessment Method (NCSAM)
assessment provided in the application package.
Two State permits have been previously issued to the Wilmington Intemational Airport. State Permit No. 8748, issued on
August 10.2018 authorized impacts to streams and wetlands by installing concrete culvert pipe to mitigate wildlife attraction
in wetland areas within the airfield. State Permit No. 87-18 expires on December31, 2021. State Permit No.16-10, issued
on February 5, 2010 authorized expansion of a concrete platform over wetlands as a part of FAA required improvements
associated with runway alignment indicator lights. State Permit No.16-10 expired on November 25, 2014.
The New Hanover County Land Use Plan classifies the high ground portion of the property as Commerce and the wetland
areas as Conservation. The waters of Smith Creek are classified C; Sw by the Division of Water Resources (DWR), and
they are CLOSED to shellfishing. This section of Smith Creek and its tributaries are NOT designated as a Primary Nursery
Area (PNA) by the N.C. Division of Marine Fisheries (DMF).

PROPOSED PROJECT:
The applicant proposes to grade eroding stream banks, line the channel with an articulating concrete block system and
rip rap, and improve the perimeter fence. Excessive erosion in Stream 1 has resulted in excised unstable banks that
continuously wash sediment downstream into Smith Creek, According to the applicant, the perimeter fence has been
undermined and damaged in the vicinity of the stream creating entry ways into the RSA for both people and wildlife.
The proposed project is necessary to meet FAA requirements for public safety by restricting access to airrield areas to
mitigate the likelihood of wildlife strikes. The application indicates that the entire length of Stream 1, 316' in length by a
maximum of 66' in width (86,856 sq.ft.) will be graded to a 3:1 slope. Within the 316' of stream, 72' of stream is
considered within Areas of Environmental Concern (AEC). Due to stream meanders and erosion areas, 72' of
jurisdictional stream is within a 60' long area of the Public Trust AEC. The following impacts are only for the areas of
Public Trust and the 30' Public Trust Shoreline AEC within the project area. Grading in the stream bed or below
NHW would measure approximately 62' in length by 3' in width by 19" deep on average for an estimated total of 11
cubic yards (cy) removed. Grading proposed for the stream slope would measure approximately 62' in length by 13'
in width by 13.5" deep on average for an estimated total of 34 cy removed. Additional grading would occur outside the
adjacent stream slopes to achieve the proper 3:1 slope and would measure approximately 53' in length by 44' in width
by 4.5" deep on average for an estimated total of 32 cy removed. A total of 77 cy of eroding, unconsolidated material
is proposed to be excavated from the stream edges, bed, and banks in preparation for installing the articulating block
system and rip rap (Figure 5). Grading and slope preparation would also occur outside of the jurisdictional areas with
an estimated 255 cy of dirt to be removed. Following grading in and around the stream, pervious articulating concrete
block and rip rap would be installed to line the banks and the bottom of the stream within the impacted areas described
above. Articulating concrete block would be installed in the bed and banks of the graded stream from the perimeter
road to the fence in an area measuring approximately 30' by 16.3' for a total of 489 sq.ft., 407 sq.ft. of which is
proposed to be installed below NHW. An area measuring approximately 32' by 16.4' for a total of 525 sq.ft of rip rap
would be installed beginning under the fence to the culvert at the downstream end of the project area, 448 sq. It of
which would be installed below NHW (See page 5 of 7 in the Narrative). Areas of disturbance landward of the rip rap
and articulating concrete block will be stabilized using seed and matting or other means of erosion control.
According to the applicant, all work will occur during dry conditions. The upstream culvert pipe will be blocked, and any
stormwater drainage will be pumped around the project area into the downstream portion of the UT. Similarly, the
downstream culvert will be blocked to prevent tidal flow from entering the project area. The applicant proposes to
relocate the perimeter fence to the top of the downstream culvert temporarily during the proposed grading and
installation of the articulating concrete block. The fence would be placed back in its current location with the addition of
smooth metal bars placed every 4" on center at the bottom of the fence secured in a concrete beam measuring 12' in
length by 12" in width and 12" in height below ground, under the riprap. The concrete to hold the bars in place would
be new impervious surface within the AEC with approximately 3 sq.ft. below NHW and 13 sq.ft above NHW.
Additionally, a concrete headwall would be constructed at the upstream culvert ouffall, located outside of the AEC, to
mitigate future erosion around the pipe outfall. Compensatory mitigation is proposed at a 0.5:1 ratio since the
proposed project does not include avoidance or minimization efforts for impacts to jurisdictional waters. According to
the applicant the stabilization of the stream bed and bank will improve water quality downstream as aresult of reduced
sedimentation caused by erosion. The 0.5:1 mitigation ratio is proposed due to the low functional value determined
using NCSAM and the overall water quality improvement. Using the proposed mitigation ratio, 122 linear feet of
freshwater non -tidal stream credits and 36 linear feet of freshwater tidal stream credits would be purchased through the
North East Cape Fear Umbrella Mitigation Bank (NECFUMB). A Letter of Availability is provided by the applicant.
10. ANTICIPATED IMPACTS:
The proposed project area consists of high ground, and Public Trust Areas including open water (freshwater tidally
influenced stream). A total area approximately 3,324 sq. ft is proposed to be disturbed by grading activities. The proposed
stabilization using articulating concrete block and rip rap injurisdictional areas would fill a total of approximately 855 sq.ft.
below NHW and fill approximately 159 sq.ft. above NHWwithin the graded area in the AEC. Approximately 2,310 sq. ft. of
the graded area would be stabilized using vegetated erosion control methods. Approximately 16 sq.ft. of impervious

concrete would be located below the riprap within the AEC to support the metal rods that would extend from the fence to
help ensure public safety and comply with FAA rules and regulations (See tables on page 5 of 7 in the Narrative). The
proposed stabilization would be located in Sw waters with no SAV habitat, temporary increased in turbidity during the
project are expected.

Re: Wilmington International Airport - FEMA Ditch/Drainage Runoff Mitigation
Wilmington, New Hanover County
CAMA Major Development Permit Application Submittal
W R Project #03110288.60
Dear Ms. Elks:
The New Hanover County Airport Authority requests a CAMA Major Development Permit for the
Ditch/Drainage Runoff Mitigation project at the Wilmington International Airport (ILM). The
proposed project is located at the Wilmington International Airport at 1740 Airport Blvd in
Wilmington, New Hanover County, North Carolina (Lat: 34.260964°N; Long:-77.913153°W).
The Wilmington International Airport (PARID: PID: R04200-001-025-000) is in the Cape Fear
River Basin (HUC 03030007) and onsite waters drain to Smith Creek. The Water Quality
Classification for Smith Creek is C;Sw and the Stream Index Number is: 18-74-63. Smith Creek is
classified as an 'Inland Water" by the NC Division of Marine Fisheries.
Proposed Proiect
The purpose of the proposed project is to meet FAA requirements by mitigating public safety
hazards associated with aircraft travel by preventing human and wildlife access within the airfield
at the project location to improve aircraft safety. The proposed project will address excessive
erosion within the stream feature (Stream 1) resulting from extraordinary rainfall and flooding from
Hurricane Florence which destabilized the channel. Stream 1 is the outlet for the stormwater
drainage system for approximately 37-acres within the airport. The erosion within the channel
continues to get worse with each heavy rainfall event and has eroded out a large area underneath
the perimeter security fence. The erosion continues to widen the channel at the perimeter security
fence, resulting in the airport maintenance regularly having to block the new holes under the fence
with metal rods. The metal rods then catch debris, which causes the stream to erode around the
metal posts, creating a constant maintenance issue. The frequent undermining of the perimeter
security fence poses a significant security risk, as the erosion creates access points into the airfield
for both humans and wildlife at the Runway 6 approach. The erosion and sedimentation have
also created conditions within the channel that is attracting wildlife. These conditions create a
safety issue as Stream 1 is within the Runway 6 Approach and approximately 800 If from the end
of Runway 6, greatly increasing the likelihood of a wildlife strike with an aircraft. In 2018, a small
passenger aircraft struck a coyote on the runway, and the proposed project is critical to improving
aircraft and public safety.

FEMA Ditch/Runoff Drainage Mitigation Project , ;
Additionally, the head cut from the erosion has progressed approximately 300 If upstream from
the perimeter security fence to the perimeter road culvert in approximately 18-months. If not
addressed, the erosion will undercut the perimeter road culvert and continue upstream,
threatening the integrity of Runway 6. Since the initial damage to the stream channel and ensuing
erosion resulted from flooding from Hurricane Florence, the proposed project is being funded by
FEMA. FEMA prepared a Record of Environmental Consideration (REC) in accordance with NEPA,
which determined that the proposed project met conditions for authorization under a CATEX
category `N9 - Federal Assistance for Flood Hazard Reduction Actions. The FEMA REC has been
provided as an attachment.
The proposed project proposes to permanently impact Stream 1, of which approximate 72 If is
tidal and 244 If is non -tidal. The project proposes to grade the slopes of the channel and
surrounding areas to a 3:1 slope and line the entire channel with an articulating concrete block
geogrid system and riprap which will permanently stabilize the channel and prevent future erosion
and undermining of the perimeter security fence, permanently eliminating the reoccurring safety
issue at this location. The articulating concrete block liner is pervious, allowing water to infiltrate
through it, as well as vegetation to grow up through it and has been used to successfully stabilize
other onsite stormwater swales at ILIA (see Photo Documentation).
The stream channel will be lined from the existing perimeter road culvert to an existing culvert
approximately 30 ft southwest of the existing security fence. This culvert is located within the
CFPUA sewer maintenance access road. The articulating block will be installed within the stream
from the perimeter road culvert to the security fence, with the section of stream from the security
fence to the downstream culvert lined with riprap to dissipate flow, stabilize the channel, and
protect the culvert from erosion and undercutting. A concrete headwall will be constructed on the
upstream end of the existing culvert to provide permanent stabilization and protection of the
culvert. Additionally, a concrete headwall will be constructed on the downstream end of the
perimeter road culvert.
The perimeter security fence will be temporarily relocated over the existing culvert to the
southwest during construction but will be reconstructed in its current location once construction
is complete. Metal bars will be installed extending from the bottom of the fence through the
channel to provide prevent access under the fence by wildlife or humans. The metal bars will be
installed approximately 4" apart and will be anchored in a 12" long x 12" wide x 12" high concrete
beam that will be installed below ground directly below the fence (see Figure 3 in Impact Maps).
A portion of Stream 1 inside of the perimeter security fence is an inland -tidal stream. However,
per previous NCDCM determinations on similar projects at the Wilmington International Airport,
CAMA jurisdiction stops at the existing security fence as the portions upstream of the perimeter
security fence are not navigable. Therefore, the tidal portions of Stream 1 upstream of the security
fence are considered Section 404/10 waters but are not subject to CAMA jurisdiction. The portion
of Stream 1 downstream of the security fence is considered navigable waters subject to CAMA
jurisdiction.
The completion of the project will increase aircraft and public safety as part of the normal daily
operation and activities associated with the operation of the airport. Please note that the
proposed project will not create any additional impervious area and will not change the existing
volume of stormwater drainage discharging into downstream portions of Stream 1.

Project History
Since the initial damage to the stream channel and ensuing erosion resulted from Hurricane
Florence, the proposed project is being funded by FEMA. FEMA prepared a Record of
Environmental Consideration (REC) in accordance with NEPA, which determined that the
proposed project met conditions for authorization under a CATEX category "N9 - Federal
Assistance for Flood Hazard Reduction Actions. The FEMA REC has been provided as an
attachment.
An onsite pre -application meeting was conducted with Patrick Amico with the NC Division of
Coastal Management (NCDCM) and Robb Mairs with the NC Division of Water Resources
(NCDWR) was conducted on 6/23/2020 to review Stream 1 and determine the limits of tidal
influence and discuss the proposed project. The limits of tidal influence are depicted in the
attached CAMA plans and exhibits.
An additional onsite pre -application meeting was conducted with Katharine Elks (NCDCM) and
Joanne Steenhujs (NCDWR) on 1/11/2021 to review and discuss the project.
The 30' CAMA AEC, as confirmed by NCDCM staff, extends 30 ft northeast of the perimeter
security fence and into the project area as shown on the attached CAMA Impact Plans and exhibits.
In addition to the two onsite pre -application meetings with NCDWR, WithersRavenel submitted a
the NCDWR Pre -Filing Meeting Request on 12/29/2020. A copy of the submittal confirmation
has been provided as an attachment to this application. Therefore, the requirement for requesting
a pre -filing meeting under 40 CFR Part 121 for 401 Certifications in accordance with the federal
Clean Water Act have been satisfied.
WithersRavenel completed a delineation of the project area in June 2020. There are no wetlands
within the project area. The only jurisdictional feature present is Stream 1, of which 72 If is inland -
tidal and 244 If is non -tidal. A Preliminary JD Exhibit and upland data form have been provided in
support of the delineation. Please note that we are not requesting issuance of a JD in conjunction
with issuance of the 404 permit from the USACE.
The Wilmington International Airport has received authorizations for three previous Wildlife
Hazard Mitigation projects that involved removal of wildlife habitat as required by the FAA. The
projects were:
• ILM Runway 24 Wildlife Hazard & NAVAID Critical Area Mitigation - 2014
o USACE 404 Individual Permit (AID# SAW-2011-00455)
o NCDWR Individual 401 WQC (Project #13-1263)
• ILM Wildlife Hazard Mitigation Project - 2017
o USACE NWP 39 (AID# SAW-2016-00075)
o NCDWR 401 WQC (Project #2017-0798)
ILM Wildlife Hazard Mitigation Project for Wet Detention Basins and Open Ditches - 2018
o CAMA Major Development Permit (permit #87-18)
o USACE GP 291(AID# SAW-2016-00075)

The cumulative impacts associated with previous permitted actions at the airport exceed
thresholds for requiring mitigation, and therefore the applicant is proposing to provide mitigation
for the proposed impacts associated with the current project.
Existing Conditions
The project area is located within the active airfield, which is maintained/mowed regularly to
manage vegetation at very low heights as required by the FAA. The project area is located within
to the Runway Safety Area (RSA) of Runway 6.
The project area contains a perennial UT to Smith Creek (Stream 1). The vegetation within the
areas outside of Stream 1 is regularly mowed/maintained. It is unclear is Stream 1 is a channelized
natural stream or was an excavated ditch that naturalized into a stream. The banks of Stream 1
are very steep, and erosion has caused bank failure and downcutting of the stream channel and
resulted in significant sedimentation of the downstream section of Stream 1, and ultimately Smith
Creek.
Areas of Environmental Concern
Stream 1 is an inland tidal UT to Smith Creek, which is classified as C;Sw, and is subject to a 30'
CAMA Area of Environmental Concern (AEC). NCDCM has determined that CAMA jurisdiction
stops at the perimeter security fence, as the upstream portions of Stream 1 are not navigable. The
30' AEC extends 30 ft northeast of the perimeter security fence and encompasses approximately
0.08 acres (3,513 sq ft) of the project area. While the proposed project will not result in impervious
area within the 30' AEC, the entire 30' AEC within the project area will be graded and filled.

Ucland Development
The proposed upland development consists of the excavation and grading of the uplands
immediately adjacent to Stream 1 to lay back the slopes to a 3:1 slope for installation of the
articulating concrete block system.
Proposed Impacts
The proposed impacts consist of the following permanent impacts to Stream 1:
• Stream 1(non-tidal) - 244 If (Impact #1)
• Stream 1(tidal non -navigable) - 31 If (Impact #2) MAR 0 4 202)
• Stream 1(tidal-navigable) - 41 If (Impact #3)

21
The proposed impacts are necessary to correct the erosion within Stream 1 which is causing a
reoccurring security issue by undermining the perimeter security fence and creating openings
through which humans and wildlife can access the airfield. Since the erosion is occurring within a
jurisdictional stream, impacts could not be avoided or minimized. it should be noted that Stream
1 is highly degraded and has low functional value because of the erosion within the channel and
historic maintenance.
Stream 1 is a perennial stream which was historically channelized to convey stormwater drainage
within approximately 37-acres within the airport beyond the perimeter fence and into Smith
Creek. Stream 1 experiences significant erosion of the banks and downcutting of the stream bed
with every rain event, resulting in sedimentation of the downstream section of Stream 1 and

.,,oie .,,,,, s,,.
ultimately Smith Creek. The proposed impacts from lining of Stream 1 will result in overall
improvements to the water quality within downstream portions of Stream 1 and Smith Creek by
eliminating the current erosion and sediment transport into these streams. WithersRavenel
conducted an NCSAM functional assessment of Stream 1, which determined that the functional
value was "Low" (see attached NCSAM Assessment Form).
Grading of the slopes and installation of the articulating concrete block geogrid lining will be
completed "in the dry". This will be accomplished through by blocking the upstream end of the
perimeter road culvert and pumping stormwater drainage flow around the project area and back
into downstream portion of Stream 1. Additionally, the downstream culvert will also be blocked
to block tidal flow from entering the project area from downstream.
Silt fencing will be installed around all disturbed areas in accordance with the Sediment & Erosion
Control Plan, which will be reviewed and approved by NCDMLR. Upon completion of grading, all
areas will be sodded with live grass sod to provide permanent stabilization.
Mitigation
Since the proposed project does not avoid and minimize impacts to jurisdictional waters and
wetlands, compensatory mitigation is proposed.
The NCSAM assessment of Stream 1 determined the functional value to be "Low*. The proposed
lining/stabilization of Stream 1 will result in an overall benefit to the water quality of the
downstream portions of Stream 1, and ultimately Smith Creek, by eliminating the introduction of
significant levels of sediment resulting from the eroding stream bed and banks. Considering the
low functional value of Stream 1 and water quality benefits resulting from eliminating the
sedimentation from the eroding banks, a 0.5:1 mitigation ratio is proposed for the proposed stream
impacts as noted in the table below.

Please give a brief project description below.*
The purpose of the proposed project is to meet FAA requirements by
mitigating public safety hazards associated with aircraft travel by
preventing human and wildlife access within the airfield at the project
location to improve aircraft safety. The proposed project will address
excessive erosion within the stream feature (Stream 1) resulting from
extraordinary rainfall and flooding from Hurricane Florence which
destabilized the channel. Stream 1 is the outlet for the stornmater
drainage system for approximately 37-acres within the airport. The
erosion within the channel continues to get worse with each heavy
rainfall event and has eroded out a large area underneath the
perimeter security fence. The erosion continues to widen the channel
at the perimeter security fence, resulting in the airport maintenance
regularly having to block the new holes under the fence with metal
rods. The metal rods then catch debris, which causes the stream to
erode around the metal posts, creating a constant maintenance
MAR Q 4 2021

issue. The frequent undermining of the perimeter security fence
poses a significant security risk, as the erosion creates access points
into the airfield for both humans and wildlife at the Runway 6
approach. The erosion and sedimentation have also created
conditions within the channel that is attracting wildlife. These
conditions create a safety issue as Stream 1 is within the Runway 6
Approach and approlamately 800 If from the end of Runway 6, greatly
increasing the likelihood of a wildlife strike with an aircraft.
Additionally, the head cut from the erosion has progressed
apprownately 300 If upstream from the perimeter security fence to
the perimeter road culvert in approbmately 18-months. B not
addressed, the erosion will undercut the perimeter road culvert and
continue upstream, threatening the integrity of Runway 6. Since the
initial damage to the stream channel and ensuing erosion resulted
from flooding from Hurricane Florence, the proposed project is being
funded by FEMA. FEMA prepared a Record of Environmental
Consideration (REC) in accordance with NEPA, which determined that
the proposed project met conditions for authorization under a CATEX
category *W — Federal Assistance for Flood Hazard Reduction
Actions. The FEMA REC has been provided as an attachment.
The proposed project proposes to permanently impact Stream 1, of
which approbmate 72 It is tidal and 244 If is non -tidal. The project
proposes to grade the slopes of the channel to a 3:1 slope and line
the entire channel with an articulating concrete block geogrid system
which will permanently stabilize the channel and prevent future
erosion and undermining of the perimeter security fence,
permanently eliminating the reoccurring safety issue at this location.
The articulating concrete block liner is pervious, allowing water to
infiltrate through it, as well as vegetation to grow through it. The
stream channel will be lined from the ebsting culvert in the perimeter
road to an ebsting culvert approzmately 25 If downstream of the
erisbng security fence. The articulating concrete block system has
been used to stabilize other onshe stonrnvater swales at ILM and it
has been very affective (see Photo Documentation). The perimeter
security fence will be relocated over the ebsting culvert to the west to
avoid potential future issues with erosion compromising the perimeter
security fence. A concrete headwall will be constructed on the
upstream and of the ebsting culvert to provide permanent
stabilization of the culvert and prevent future erosion.
The completion of the project will increase aircraft and public safety
as part of the normal daily operation and activities associated with the
operation of the airport. Please note that the proposed project will not
create any additional impervious area and will not change the wasting
volume of stormwater drainage discharging into downstream portions
of Stream 1.
The project will require a CAMA major development permit as well as
a 401 WQC.

3e. Describe the overall project in detail, including the type of equipment to be used:
The proposed project will address excessive erosion within the stream feature (Stream 1) resulting from extraordinary
rainfall and flooding from Hurricane Florence which destabilized the channel. Stream 1 is the outlet for the stormwater
drainage system for approximately 37-acres within the airport. The erosion within the channel continues to get worse with
each heavy rainfall event and has eroded out a large area underneath the perimeter security fence. The erosion
continues to widen the channel at the perimeter security fence, resulting in the airport maintenance regularly having to
block the new holes under the fence with metal rods. The metal rods then catch debris, which causes the stream to
erode around the metal posts, creating a constant maintenance issue. The frequent undermining of the perimeter
security fence poses a significant security risk, as the erosion creates access points into the airfield for both humans and
wildlife at the Runway 6 approach. The erosion and sedimentation have also created conditions within the channel that
is attracting wildlife. These conditions create a safety issue as Stream 1 is within the Runway 6 Approach and
approximately 800 If from the end of Runway 6, greatly increasing the likelihood of a wildlife strike with an aircraft. In
2018, a small passenger aircraft struck a coyote on the runway, and the proposed project is critical to improving aircraft
and public safety.
Additionally, the head cut from the erosion has progressed approximately 300 If upstream from the perimeter security
fence to the perimeter road culvert in approximately 18-months. If not addressed, the erosion will undercut the perimeter
road culvert and continue upstream, threatening the integrity of Runway 6. Since the initial damage to the stream
channel and ensuing erosion resulted from flooding from Hurricane Florence, the proposed project is being funded by
FEMA. FEMA prepared a Record of Environmental Consideration (REC) in accordance with NEPA, which determined
that the proposed project met conditions for authorization under a CATEX category'N9 — Federal Assistance for Flood
Hazard Reduction Actions. The FEMA REC has been provided as an attachment.
The proposed project proposes to permanently impact Stream 1, of which approximate 72 If is tidal and 244 If is non -tidal.
The project proposes to grade the slopes of the channel and surrounding areas to a 3:1 slope and line the entire channel
with an articulating concrete block geogrid system and riprap which will permanently stabilize the channel and prevent
future erosion and undermining of the perimeter security fence, permanently eliminating the reoccurring safety issue at
this location. The articulating concrete block liner is pervious, allowing water to infiltrate through it, as well as vegetation
to grow up through it and has been used to successfully stabilize other onsite stormwater swales at ILM (see Photo
Documentation).
The stream channel will be lined from the existing perimeter road culvert to an existing culvert approximately 25 If
downstream of the existing security fence. This culvert is located within the CFPUA sewer maintenance access road.
The articulating block will be installed within the stream to the security fence, with the section of stream from the security
fence to the downstream culvert lined with riprap to dissipate flow, stabilize the channel, and protect the culvert from
erosion and undercutting. A concrete headwall will be constructed on the upstream end of the existing culvert to provide
permanent stabilization and protection of the culvert.
The perimeter security fence will be temporarily relocated over the existing culvert to the west during construction but will
be reconstructed in its current location once construction is complete. Metal bars will be installed extending from the
bottom of the fence through the channel to provide prevent access under the fence by wildlife or humans. The metal bars
will be installed approximately 4' apart and will be anchored in a concrete beam will be installed below ground directly
below the fence (see Figure 3 in Impact Maps).
A portion of Stream 1 inside of the perimeter security fence is an inland -tidal stream. However, per previous NCDCM
determinations on similar projects at the Wilmington International Airport, CAMA jurisdiction stops at the existing security
fence as the portions upstream of the perimeter security fence are not navigable. Therefore, the tidal portions of Stream
1 upstream of the security fence are considered Section 404/10 waters but are not subject to CAMA jurisdiction. The
portion of Stream 1 downstream of the security fence is considered navigable waters subject to CAMA jurisdiction.
The completion of the project will increase aircraft and public safety as part of the normal daily operation and activities
associated with the operation of the airport. Please note that the proposed project will not create any additional
impervious area and will not change the existing volume of stormwater drainage discharging into downstream portions of
Stream 1.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
Ia. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed impacts are necessary to correct the erosion within Stream 1 which is causing a reoccurring security issue by
undermining the perimeter security fence and creating openings through which humans and wildlife can access the airfield.
Since the erosion is occurring within a jurisdictional stream, impacts could not be avoided or minimized. It should be noted
that Stream 1 is highly degraded and has low functional value as a result of the erosion within the channel and historic
maintenance.
Stream 1 is a perennial stream which was historically channelized to convey stormwater drainage within approximately 37-
acres within the airport beyond the perimeter fence and into Smith Creek. Stream 1 experiences significant erosion of the
banks and downcutbng of the stream bed with every rain event, resulting in sedimentation of the downstream section of
Stream 1 and ultimately Smith Creek. The proposed impacts from lining of Stream 1 will result in overall improvements to the
water quality within downstream portions of Stream 1 and Smith Creek by eliminating the current erosion and sediment
transport into these streams. WithersRavenel conducted an NCSAM functional assessment of Stream 1, which determined
that the functional value was "Low".
Grading of the slopes and installation of the articulating concrete block lining will be completed "in the dry". This will be
accomplished through by blocking the upstream end of the perimeter road culvert and pumping stormwater drainage flow
around the project area and back into downstream portion of Stream 1. Additionally, the downstream culvert will also be
blocked to block tidal flow from entering the project area from downstream.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Access during construction will be in uplands. Silt fencing will be installed around all disturbed areas in accordance with the
Sediment & Erosion Control Plan, which will be reviewed and approved by NCDMLR. Upon completion of grading, all areas
will be sodded with live grass sod to provide permanent stabilization.

S. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or
❑Yes No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act
®Yes ❑ No
impacts.
5c. If yes, indicate the USFWS Field Office you have contacted.
® Raleigh
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
SWR reviewed the NC Natural Heritage Program database, located at https://ncnhde.natureserve.org/, as well as
NCNHP GIS data to identify if there were any known occurrences of endangered species on or near the proposed project.
The review of the NHP data did not identify any recent occurrences of federally listed threatened or endangered species
or critical habitat on the subject property or within 1.0 miles of the project, see attached NCNHP project review letter.
Furthermore, site reviews did not identify any potential habitat for any federally protected species known to occur in New
Hanover County. Therefore, WR concludes that the proposed project will not adversely affect federally listed species or
their designated critical habitat.
Please note that in 2017 the USFWS issued a previous determination of "not likely to adversely affect" for the Wildlife
Mitigation Project for Wet Detention Basins and Open Ditches (AID: SAW-2016-00075) at ILM which consisted of similarly
situated project impacting an unnamed tidal tributary to Smith Creek.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?
❑ Yes ®No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
WR reviewed the NOAA Essential Fish Habitat online mapper, located at:
http:/fwww.habitat.noaa.gov/protection/efh/efhmapperfndex.htmi* The EFH mapper classifies the Cape Fear River, located
approximately 5 miles west of the project areas, as Essential Fish Habitat. However, the project will have sediment &
erosion control measures in place to prevent sediment from escaping into downstream water, and therefore will not result
in adverse impacts to EFH within the Cape Fear River.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal
governments have designated as having historic or cultural preservation
El Yes ®No
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
WR reviewed the NC State Historic Preservation Office's online database, located at: http://Qis.ncdcr.gov/hpoweb/, to
determine if there were any known historic or cultural resources within or in the vicinity of the proposed project. The
database review did not identify any known resources within or in the vicinity of the proposed project. Additionally, SHPO
has determined that previous projects in the immediate vicinity of the proposed project would not affect historic resources.
