Re: Airlie Gardens - Stream and Lake Water Quality Improvements - NWP 27 PCN Submittal
Wilmington, New Hanover County
WR Project #02160707.00
Dear Ms. Capito and Ms. Higgins,
On behalf of New Hanover County/Airlie Gardens, we are requesting authorization from the
USACE to use NWP 27 for 0.024 acres of permanent wetland impacts, 45 If of permanent stream
impacts and 25 If of temporary stream impacts, 8.34 acres of temporary open water impacts and
0.49 acres of permanent open water impacst for the proposed project. We are also requesting a
401 WQC from NCDWR for the above referenced impacts.
The project is located in Airlie Gardens, which is a ±59.71 acre park owned by New Hanover
County, located at 300 Airlie Road in Wilmington, New Hanover County (Lat: 34.217477°N; Long:
-77.828714°W). The proposed project and associated impacts are located around the UT to
Bradley Creek and the onsite lake (see Appendices). The project is located in the Cape Fear River
basin and onsite waters drain to Bradley Creek. The Water Quality Classification for Bradley Creek
is SC:# and the Stream Index Number is: 18-87-24-4-(2). The cataloging unit for the site is
03020302.00 (White Oak).
Proposed Project
The purpose of the proposed project is to improve the overall water quality and aquatic habitat
within the onsite perennial stream and Airlie Gardens' lake, and ultimately Bradley Creek, by
reducing the amount of sediment being transported into the lake. Additionally, the project will
improve water quality and enhance the aquatic habitat within the lake by dredging the
accumulated sediment to increase lake depths and create areas of various depths in order to
establish aquatic habitat zones of varying depths in order to provide habitat for the many stages
of the life cycle of the aquatic fauna that inhabits the lake. The proposed project is being funded
by a Clean Water Management Trust Fund grant, which was awarded to the project based on the
overall environmental benefit generated from the project.
The perennial stream (UT to Bradley Creek) draining into the onsite lake originates at a culvert
beneath Airlie Road. The runoff from the entire ±124 acre upstream watershed is captured and
conveyed through a series of stormwater drainage systems, which ultimately outfall into the
perennial stream at its origin. Additionally, there are two storm drainage pipes that discharge
runoff from Airlie Road and nearby development directly into the stream. Currently,

approximately 33% (42 acres) of the watershed is impervious area. It is estimated that at buildout,
the total impervious area within the watershed will increase to 40% (±50.4 acres). The runoff
coming from the impervious area within the watershed contains a significant amount of sediment,
nutrients and trash, all of which ends up in the perennial stream and lake. With the additional
impervious area within the watershed at build out, the amount of sediment, nutrients and trash
discharging into the perennial stream and lake will only increase. The proposed activities to
improve water quality must not only take into account current conditions, but also future
conditions in order to provide a long term solution to the problems.
Under normal conditions, there is minor flow within the stream, as the stream acts as backwater
of the lake. Following a rain event, there is high flow velocity coming into the stream from the
upstream stormwater drainage system, which carries high levels of sediment. As flow decreases,
the backwater conditions result in the sediment suspending and depositing within the stream and
lake. Currently, the perennial stream has a substantial amount of sediment deposition, resulting
in the stream being choked with sediment to the point that the channel has migrated from its
historic location and configuration, resulting in a very wide, shallow stream. Additionally, the lake
has so much sediment deposition that the water depths are very shallow. Based on a bathometric
survey of the lake, water depths range from less than 1' deep at the head of the lake to 4'-5' deep
at the deepest points, with the majority of the lake being less than 5' deep. The historic depths
were 5' to 8' in depth. These shallow depths have created poor water quality, higher water temps
and low dissolved oxygen levels, resulting in algal blooms every summer, an abundance of exotic
and nuisance aquatic vegetation and fish kills. In order to provide a temporary solution to these
problems, Airlie Gardens has installed 5 bubblers within the lake to increase the dissolved oxygen,
and use chemicals approved for treatment of algal blooms and exotic and invasive aquatic plants
(e.g. alligator weed).
The proposed project consists of several proposed activities that will improve the overall water
quality of the UT to Bradley Creek, the onsite lake and ultimately Bradley Creek.
Water Quality and Aquatic Habitat Improvements to Perennial Stream above Lake
The proposed improvements to the perennial stream begin with the construction of a plunge pool
at the stream origin, immediately below the two main storm drainage pipes that discharge into the
stream. The construction of the plunge pool will result in 45 If of permanent stream impacts and
0.006 acres of permanent wetland impacts. Additional uplands will be excavated to create a larger
plunge pool, which will reduce the velocity of flow from the culverts, allowing sediment to suspend
out of the water column before flowing over the proposed check dam and into the perennial
stream. This will significantly reduce the sediment deposition within the stream and lake.
Selective removal of excessive sediment within the stream will be conducted to removal blockages
within the stream (Impact 4). The removal of the accumulated sediment will improve the water
quality within the stream, as well as create a more diverse habitat for aquatic life.
The proposed improvements also include creation of floodplain on the southern side of the
perennial stream. Currently, there is very little floodplain adjacent to the stream. This will be
accomplished by excavating the adjacent uplands and grading a gentle slope beginning at the 4.5'
Page 2 of 6

elevation, which will allow water to spill over the banks of the stream (4.0' elevation) and into the
floodplain area during periods of high flow (see Site Plan). The floodplain area will provide
additional storage of floodwaters, allowing the flow velocities to reduce and sediment to suspend
out and be deposited in the floodplain, further reducing the amount of sediment deposition within
the stream and lake. The floodplain will be planted with a mixture of native herbaceous and woody
vegetation adapted for inundated and wet conditions as noted in the Landscape Plan (Sheet C5.0),
which has been provided as an Appendix. While the creation of the floodplain will result in 0.018
acres of permanent wetland impacts, it is anticipated that the floodplain areas will transition to
wetlands over time, creating more wetlands than will be impacted.
A temporary horseshoe dam will be installed within the stream immediately upstream of the
culvert beneath the walking trail, resulting in 6 If of temporary stream impacts. The horseshoe
dam will provide sediment and erosion control during construction. The horseshoe dam will be
constructed by stacking Class 1 rip -rap in a horseshoe configuration from bank to bank. #57
washed stoned will then be placed on the upstream side of the horseshoe dam. The horseshoe
dam will filter water flowing from the construction area, preventing turbidity issues within the lake.
Upon completion of construction, the horseshoe dam will be removed.
Water Quality and Aquatic Habitat Improvements within Lake
The proposed water quality and habitat improvements within the lake will be accomplished
through dredging/removal of the accumulated sediment within the lake. The water level of the
lake will be drawn down to dry lake bed while still maintaining a small area of flow through the
bottom of the pond. The proposed dredging will be conducted using excavators to remove
accumulated sediment and increase the depth of the pond. During sediment removal, double
handling of spoil will be minimized to the greatest extent possible. All dredge spoil will be
transported with a dump truck and stockpiled within the ±1.8 acre spoil stockpile area, which is
located within the grassed parking area between the visitor center and lake. Stockpiled spoil will
be stored for approximately 90 days, allowing enough time for the spoil to dry out before being
transported to the New Hanover County Landfill. The dredge spoil stockpile area will be lined
with silt fencing in order to prevent sediment and turbid water from escaping the stockpile area.
By increasing the overall depth of the lake, the water temperatures will be less vulnerable to solar
heating, the dissolved oxygen levels will increase, and there will be less invasive vegetation and
fewer algal blooms. This will improve the overall water quality within the lake, and prevent future
fish kills. Additionally, Airlie Gardens will not need to manage the invasive aquatic plants and algal
blooms with chemicals, further improving water quality within the lake. Ultimately, the
improvements to the water quality within the lake will also provide a water quality benefit to
Bradley Creek, as the lake drains into Bradley Creek.
The sediment dredging/removal will be completed in a method that will create varying depths in
areas throughout the lake, rather than creating a uniform depth throughout. The dredged depths
will vary from 1.5' deep to 7' deep throughout the lake. This will create different areas of habitat,
which will provide habitat for the different phases of the life cycle of the aquatic life that inhabits
the lake, promoting ecological diversity. The creation of diversified habitat include shallower
shelves for spawning, deeper areas for wintering, and different depths for feeding cycles

throughout the year. This will also create additional foraging habitat for wading birds and
waterfowl, so the habitat improvements will be beneficial to more than just aquatic life. There is
no predetermined design for the proposed dredging and aquatic habitat creation. The creation of
these features will be determined once the lake has been drained so that the bottom can be
observed, and the natural contours and underwater structures will be utilized to create and
enhance habitat diversity.
The causeway that bisects the lake has 6 -inch wide vertical concrete retaining walls on both sides
of the causeway. The proposed project includes the creation and planting of a living shoreline on
both sides of the retaining wall. The living shoreline will be created by placing dredged sediment
adjacent to the wall and creating an 8:1 slope from the retaining wall into the lake. The slope will
then be planted with native aquatic vegetation, creating a ±45 ft wide littoral shelf. Please note
that the planting plan for the living shoreline has not been completed yet, as this activity is slated
to begin in late 2019. A copy of the planting plan will be provided once finalized. The living
shoreline will provide additional protection for the causeway, while also providing water quality
improvements as the vegetation will help filter nutrients and sediment from the water. The living
shoreline will also provide additional shallow water habitat that will serve as spawning areas and
shelter forjuvenile aquatic species, as well as provide wading bird and waterfowl foraging habitat.
All proposed activities will be completed by Dragonfly Pond Works, which has extensive
experience with these types of projects. Additional information on Dragonfly Pond Works
experience and project examples can be found at: http://dragonflypondworks.com/.
Wetland Enhancement
The proposed wetland enhancement consists of supplemental planting of native vegetation with
a small wetland on the east side of the lake. Hurricane Florence destroyed most of the mature
trees within this wetland. The wetland will be planted with:
• 3 - Bald Cypress (Taxodium distichum)
• 2 - Pond Cypress (Taxodium distichum var. Imbricarium)
• 1 - Swamp Tupelo (Nyssa biflora)
• 32 - Green Bulrush (Scirpus atrovirens)
The purpose of the proposed planting is to establish native vegetation that is adapted to the wetter
conditions. As surrounding development has altered the natural drainage patterns, this wetland
now has a longer hydroperiod, resulting in longer periods of inundation than it had historically.
This change in hydrologic conditions stressed the existing trees and vegetation, which led to the
trees within this wetland falling during Hurricane Florence. The proposed vegetation to be planted
is adapted to the wetter conditions, and will provide an overall enhancement of the wetland.
The proposed trees to be installed will be ball and burlap, and therefore the entire 0.101 acre
wetland has been assessed as a temporary impact (Impact 7). Installation will require the use of a
small excavator to dig the holes and place the trees in the holes. During excavation of the holes,
the spoil will be placed on sheets of plywood. Once each tree is planted, the excess spoil will be
loaded onto a UTV/trailer and hauled to an upland area for disposal. The excess spoil will not be
left in the wetland.

Dur People. Your 5mcess.
Onsite wetlands were delineated by WithersRavenel in June 2018. A Preliminary JD Request has
been provided as an Appendix in support of the delineation. Please note that WR is not requesting
issuance of a PJD in conjunction with issuance of the NWP 27.
An onsite pre -application meeting was conducted with Rachel Capito (USACE), Chad Coburn
(NCDWR) and Brooks Surgan (NCDCM) on 12/4/18. At this meeting, the project areas were
discussed and the project areas were reviewed. Additionally, Brooks Surgan flagged the Normal
High Water line of Bradley Creek, which is outside of the project area.
In an email dated 12/6/18, Brooks Surgan confirmed that there is no connection from Bradley
Creek to the Airlie Gardens' lake, and therefore the proposed dredging would not require a CAMA
permit. A copy of Mr. Surgan's email has been provided as an Appendix.
In a phone conversation with Rachel Capito (USACE), Ms. Capito requested that an NCSAM
assessment be completed for the perennial stream to document the existing functional value,
which can be compared to a post -construction NCSAM assessment to confirm that the project
results in a functional improvement within the stream.
Proposed Impacts
The proposed impacts consist of:
• Plunge Pool - 45 If of permanent stream impacts (Impact 1) and 0.006 acres of permanent
wetland impacts (Impact 2).
• Floodplain Enhancement - 0.018 acres of permanent wetland impacts (Impacts 3 & 5)
• Sediment Removal within the Stream - 19 If (172 sf) of temporary stream impacts (Impact
4)
• Temporary Horseshoe Dam - 6 If of temporary stream impacts (Impact 6)
• Wetland Enhancement - 0.101 acres of temporary wetland impacts (Impact 7)
• Lake Dredging - 8.34 acres of temporary open water impacts (Impacts 8 & 9)
• Living Shoreline -0.49 acres of permanent open water impacts (Impacts 10 & 11)
Avoidance and Minimization
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted
so that impacts to wetlands and "waters" could be minimized.
Due to the nature of the project, impacts could not be avoided. Impacts have been minimized to
only those necessary to improve water quality and aquatic habitat within the project area.
Permanent stream impacts were minimized by expanding the plunge pool into the uplands to meet
the necessary sizing, rather than extending the plunge pool further down the stream.

Impacts have also been minimized by designing the project to access the project areas via existing
roads, trails and uplands. Additionally, sediment and erosion control BMPs will be in place during
proposed activities to prevent the escape of sediment and turbid water.
Mitigation
Mitigation is not required for impacts authorized under a NWP 27.
The current request is for 0.024 acres of permanent wetland impacts, 45 If of permanent stream
impacts, 25 If of temporary stream impacts, 0.49 acres of permanent open water impacts and
8.34 acres of temporary open water impacts (see the attached maps and PCN for details).

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands
and "waters" could be minimized.
Due to the nature of the project, impacts could not be avoided. Impacts have been minimized to only those necessary to
improve water quality and aquatic habitat within the project area.
Permanent stream impacts were minimized by expanding the plunge pool into the uplands to meet the necessary sizing,
rather than extending the plunge pool further down the stream.
Impacts have also been minimized by designing the project to access the project areas via existing roads, trails and uplands.
Additionally, sediment and erosion control BMPs will be in place during proposed activities to prevent the escape of sediment
and turbid water.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or
® Yes ❑ No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act
® Yes ❑ No
impacts?
® Raleigh —John Ellis
5c. If yes, indicate the USFWS Field Office you have contacted.
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
WR reviewed the NC Natural Heritage Program database, located at http://www.ncnhp.org/web/nhp/home, 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 occurrences of federally listed threatened or endangered species or
critical habitat within Airlie Gardens, see attached NCNHP project review letter.
The NCNHP GIS data identified potential habitat for two federally listed marine species, the Atlantic Sturgeon and West
Indian Manatee. There is no habitat for these species, or any other federally listed marine species or species that only
occur on the beaches or barrier islands, as the onsite lake is a freshwater lake with, created back in the early 1900's by
damming the UT to Bradley Creek. The normal pool elevation of the lake is several feet higher than the NHW elevation of
Bradley Creek, and there is not tidal connection to Bradley Creek. Therefore, the proposed project will have No Effect on
listed species potentially occurring within Bradley Creek.
Site reviews did not identify any potential habitat for any federally protected species known to occur in New Hanover
County, except for the Northern Long Eared Bat (T) and American Alligator (T S/A).
Northern Long -Eared Bat - The project will result in the removal of trees greater than 3" DBH during construction, which
is considered potential roosting habitat. However, the project is not located within 0.25 miles of a known maternity roost
or red HUC. Therefore, the project meets conditions for eligibility under the SLOPES Alternative Local Procedure —
Situation 1.
American Alligator — The Airlie Garden's lake was considered potential habitat for the American Alligator, which is listed
at Threatened due to similarity of appearance to the American Crocodile, but are not protected themselves. There are no
American Crocodiles known to exist in North Carolina, and therefore the proposed project will have No Effect on the
American crocodile.
Additionally, efforts will be made to avoid harming any American alligators that may be in the lake during sediment
removal and habitat enhancements within the lake. Based on a phone conversation on 12/12/18 with John Ellis with the
USFWS Raleigh Office, formal consultation is not required for an effect determination for the American Alligator since it is
only protected due to similarity in appearance to the American crocodile, and the project is not located within the known
range of the American crocodile.
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://www.habitat.noaa.gov/protection/efh/efhmapper/index.html. The EFH mapper classifies Bradley Creek, located
adjacent to the southern boundary of Airlie Gardens, as Essential Fish Habitat. The proposed stream/floodplain
enhancement has been designed to provide sedimentation and erosion control measures that will prevent turbidity within
the lake and ultimately Bradley Creek. Additionally, during the proposed dredging within the lake, the lake level will be
drawn down to low enough levels to stop the lake from discharging into Bradley Creek during dredging, thereby preventing
turbid water from escaping into Bradley Creek. As a result of the sediment and erosion control measures and construction
techniques to be used, the project will not result in adverse impacts to Essential Fish Habitat within Bradley Creek.

PCN Form — Version 1.3 December 10, 2008 Version

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
® 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://gis.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 identified the Bradley -Latimer Summer House (HPO Site ID: NH0581) to the west and Mount Lebanon
Chapel and Cemetery (HPO Site ID: NH0582) to the east. Both historic structures are located outside of Airlie Gardens
and outside of the project area, and will not be impacted by the proposed project.
8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA -designated 100 -year floodplain?
® Yes ❑ No
8b. If yes, explain how project meets FEMA requirements: The proposed project will actually result in additional floodwater
storage, and will not result in a rise in the 100 -year floodplain elevation. A No-Rise/No-Impact Certification is being
prepared and will be submitted to the City of Wilmington for approval.
8c. What source(s) did you use to make the floodplain determination? www.ncfloodmaps.com

Jurisdictional Determination Request
F. JURISDICTIONAL DETERMINATION (JD) TYPE (Select One)
0 I am requesting that the Corps provide a preliminary 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.
F] 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
parry" (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

Section 404

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 AJD 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 AJD to accomplish that result, as soon as is
practicable. This PJD fords 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:

Troy,
Per our site visit this week and discussions in my office regarding the proposed projects at Airlie
Gardens, we've concluded that there is no connection to the Airlie Lake and that dredging there
would not require a permit from this office.
