Dear Ms. King:
This letter is in response to the Pre -Construction Notification (PCN) you submitted to
the Wilmington District, Raleigh on February 22, 2024, for a Department of the Army
Nationwide permit (NWP) verification. This project has been assigned the file number
SAW-2024-00403 and is known as Hamilton Avenue Stormwater Utility Upgrades. This
file number should be referenced in all correspondence concerning this project.
A review of the information provided indicates that the proposed work would include
the discharge dredged/fill material in 640 linear feet (0.036 acre) of stream. This
verification authorizes the permanent discharge of fill material into 448 linear feet (0.028
acre) stream channel and the temporary discharge of fill material into 192 linear feet
(0.008 acre) of stream channel to facilitate the installation of larger stormwater pipes
throughout the streets adjoining the stormwater outlet at Oakwood Cemetery and an
upgrade of the culverts within the cemetery to facilitate the increase discharge. The
project would also involve streambank stabilization on erosive streambanks at areas of
critical infrastructure, and realignment of channel flow to reduce erosion potential in
other areas of the project reach. The project area for this determination includes 14.32
acres which is illustrated on the enclosed site plans/maps, entitled Stream Restoration
0+00 TO 1+50, G-2 and Impact Sheets 1 through 4, dated November 2020, and Final
Design, Sheets G-1, G-2, and C-1 through C-13, dated January 2024. The
project/review area is located in the Boulding Branch (Hydrologic Unit Code:
030300030102) watershed, which is within the Cape Fear River basin; at 312 Qubein
Avenue, at Latitude 35.966270 and Longitude-80.007760; in High Point, Guilford
County, North Carolina.
We have determined that the proposed work is authorized by NWP 3 and NWP 13
pursuant to authorities under Section 404 of the Clean Water Act (33 U.S.0 § 1344).
The proposed work must be accomplished in strict accordance with the general permit
conditions, any regional conditions, the special conditions listed in this letter, the

application materials, and the enclosed plans. If the extent of the project area and/or
nature of the authorized impacts to waters are modified, a revised PCN must be
submitted to this office for written approval before work is initiated. Any violation of
permit conditions or deviation from your submitted plans may subject the permittee to
enforcement action.
This verification is valid until March 14, 2026, unless prior to this date the subject
NWP(s) is suspended, revoked, or is modified such that the activity no longer complies
with the terms and conditions of this NWP. If you commence or are under contract to
commence this activity before the date that the relevant NWP is modified or revoked,
you will have 12 months from the date of the modification or revocation of the NWP to
complete the activity under the present terms and conditions of this NWP.
Project Specific Special Conditions:
Suitable habitat for tricolored bat (Perimyotis subflavus) may be present at the
site. On September 14, 2022, the United States Fish and Wildlife Service
(USFWS) published a proposal in the Federal Register to list the tricolored bat as
endangered under the Endangered Species Act (ESA). The permittee
understands and agrees that all work associated with the clearing and removal of
trees and removal or modification of culverts must be completed prior to the
effective date of the final listing of this species in the Federal Register. Work
associated with the aforementioned activities not completed by the time must
cease and the permittee must contact Laura Meyer of the Corps at (919) 634-
1595 or laura.j.meyer usace.army.mil to determine if additional coordination
with the USFWS is required under Section 7 of the ESA prior to continuing work.
Activities subject to Section 404 (as indicated above) may also require an individual
Section 401 Water Quality Certification. You should contact the NC Division of Water
Resources (telephone [phone]) to determine Section 401 requirements.
This NWP verification does not preclude the necessity to obtain any other Federal,
State, or local permits, licenses, and/or certifications, which may be required.
If you have any questions related to this verification or have issues accessing
documents referenced in this letter, please contact Laura Meyer, Regulatory Specialist
of the Raleigh at [phone], by mail at the above address, or by email at
[e-mail]. mi1.
Sincerely,
Z-a-a � ,�

partially cleared.
2. Select trees to be preserved before siting roads, buildings or
other structures.
3. Minimize trenching in areas with trees. Place several utilities
in the same trench.
4. Prohibit or restrict access to tree protection zones(TPZ). Post
"Keep Out" signs on all sides of fencing and do not store
construction equipment or materials in TPZ.
5. Monitor trees using a professional or train your staff to monitor
tree health during and after construction on a regular, frequent
basis.
6. Assign a crew member to weekly TPZ fence integrity checks.
Repair and replace TPZ fencing as needed.
MAINTENANCE:
1. Prune any damaged trees. In spite of precautions, some
damage to protected trees may occur. In such cases, repair any
damage to the crown, trunk, or root system immediately.
2. Repair roots by cutting off the damaged areas and painting
them them with tree paint. Spread peat moss or moist topsoil
over exposed roots.
3. Repair damage to bark by trimming around the damaged area,
taper the cut to provide drainage and paint with tree paint.
4. Cut off all damaged tree limbs above the tree collar at the trunk
or main branch. Use three separate cuts to avoid peeling bark
from healthy areas of the tree.

Note: After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanent ground stabilization as soon as
practicable but in no case longer than 90 calendar days after the last land disturbing
activity. Temporary ground stabilization shall be maintained in a manner to render the
surface stable against accelerated erosion until permanent ground stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
Temporary Stabilization
Permanent Stabilization
• Temporary grass seed covered with straw or
• Permanent grass seed covered with straw or
other mulches and tackifiers
other mulches and tackifiers
• Hydroseeding
• Geotextile fabrics such as permanent soil
• Rolled erosion control products with or
reinforcement matting
without temporary grass seed
• Hydroseeding
• Appropriately applied straw or other mulch
• Shrubs or other permanent plantings covered

2. Locate paint washouts at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
3. Contain liquid wastes in a controlled area.
4. Containment must be labeled, sized and placed appropriately for the needs of site.
5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from
construction sites.
PORTABLE TOILETS
1. Install portable toilets on level ground, at least 50 feet away from storm drains,
streams or wetlands unless there is no alternative reasonably available. If 50 foot
offset is not attainable, provide relocation of portable toilet behind silt fence or place
on a gravel pad and surround with sand bags.
2. Provide staking or anchoring of portable toilets during periods of high winds or in high
foot traffic areas.
3. Monitor portable toilets for leaking and properly dispose of any leaked material.
Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replace
with properly operating unit.
EARTHEN STOCKPILE MANAGEMENT
1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least
50 feet away from storm drain inlets, sediment basins, perimeter sediment controls
and surface waters unless it can be shown no other alternatives are reasonably
available.
2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of
five feet from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in accordance
with the approved plan and any additional requirements. Soil stabilization is defined
as vegetative, physical or chemical coverage techniques that will restrain accelerated
