Chris,
Please see our responses below in Red and the referenced attached information.
The applicant for a permit verification would become the permittee, and be responsible for compliance
with all regional, general, and special conditions throughout construction. Consultants are rarely, if ever,
the applicant. Please confirm.
B. Applicant Information
• 1 a. Who is the Primary Contact? Greg Davidson; Director of Land
• 1 b. Primary Contact Email: [e-mail]
• 1 c. Primary Contact Phone: [phone]
• 1 d. Who is applying for the permit? Applicant
2. Road slopes appear to be close to 1: 1, and permanent wetland impacts requested are one -thousandth of
an acre from mitigation thresholds. Were steeper fill slopes, retaining walls, or other measures to
minimize the unavoidable loss considered? Please provide additional justification for the area of loss
required. Note that as -built surveys may be required to document less than 0.01 acre of wetland was lost.
The applicant has added retaining walls on the upstream and downstream approach to reduce the
stream, wetland, and buffer temporary and permanent impacts as shown on the attached Impact
Map 1 and Impact Summary Table below. The permanent wetland impacts have been reduced
from 0.099-acres to 0.089-acres, and the permanent stream impacts have been reduced from 294
SF to 242 SF.

3. The PCN states that county water would be provided to each of the proposed lots, but no water lines are
shown on the attached plans. Please provide the proposed alignments for water infrastructure. See
attached SCM and Waterline Exhibit as well as Storm Drainage Plans. The waterline will be
constructed within the road shoulder that is part of the road crossing impact already accounted
for. There will be no additional impacts attributed to the water line.
4. The PCN states that individual sewer systems would be utilized to serve each residence. Would any
septic or repair area access across wetlands be required? No layouts for septic and service lines were
provided. There will be no impacts to jurisdictional features from the proposed septic system
areas. See attached Soil Report and in particular Figure 4A which shows the original proposed
subdivision layout with more impacts, and Figure 4 B which shows the suggested redesign to avoid
impacts, and finally the Storm Drainage Plans which shows the redesigned subdivision layout that
with proposed house locations and septic system locations that avoid impacts.
5. The PCN states that two Stormwater BMPs would be constructed to treat stormwater resulting from the
project, but none are shown on the attached plans. Please provide the location of each, as well as their
proposed discharge points. There is one dry detention type SCM that will be used to treat
stormwater run-off as shown on the attached SCM and Waterline Exhibit including the SCM
outlet discharge point.

6. Please include a project layout that includes building and septic layouts. A Licensed Soil Surveyor
report, if available, would be helpful in our review of potential future sewer related impacts. Note — this
doesn't need to be construction level design, but rather to illustrate buildout is possible without
additional impact. It is much simpler to cover these impacts now that to wait for individual landowners
to request permit modifications. There will be no impacts to jurisdictional features from the
proposed septic system areas. See attached Soil Report and Storm Drainage Plans. Septic system
layouts will be performed either by Johnston County Environmental Health during the
improvement permit process or by a licensed soil scientist during the AOWE permitting process.
Septic system layouts are not required at this time.
7. The stream impact profile view appears to show a steep head cut about 20-feet upstream of the proposed
culvert. Please provide additional detail about this feature, its likelihood of accelerated erosion once the
new culvert is installed, and weather abatement measures are warranted. The original stream impact
profile incorrectly delineated the channel bottom. The revised stream impact profile shows a more
gradual channel bottom elevation approaching the proposed culvert crossing.
8. The stream channel below the proposed crossing appears to include significant meanders. What
considerations for protecting these reaches of stream were made? Would shifting the road crossing either
up- or down -stream reduce impacts while still enabling reasonable use of the land? A portion of the
stormwater runoff that would have been directed to this section of the stream channel will be
routed through the proposed Dry Detention Pond. The detention pond discharge point is
downstream from the proposed meandering section of the stream, therefore we expect less runoff
volume through this section in the post -development scenario.
9. The PCN states that the entire tract was logged in 2021. We are unable to locate aerial photographs to
document this for our USFWS consultation. Please provide photographs of the site's current condition to
facilitate their review. See attached Goggle Earth Exhibits, the first from April 2020 which shows
the site as wooded, and the second from March 2022 which shows the site as timbered.
Please let me know if you have any questions or need additional information and as always thank -you for your
assistance!

Subject: SAW-2023-01042 / Old Fairground Road Subdivision / Angier / Johnston County, NC -REQUEST FOR
ADDITIONAL INFORMATION
Good morning, Mr. Cole:
This email is in reference to the Pre -construction notification (PCN) for the proposed Old Fairground Road
Subdivision Project (SAW-2023-01042), received on October 13, 2023.
The following information is required to complete our evaluation, confirm compliance with one or more
General or Regional Conditions, and/or complete consultation with another federal/state agency to verify the
use of the Nationwide Permit (NWP):
The applicant for a permit verification would become the permittee, and be responsible for compliance
with all regional, general, and special conditions throughout construction. Consultants are rarely, if ever,
the applicant. Please confirm.

Please provide the requested information within 30 days, or your application will be administratively
withdrawn. To clarify, if the requested information is submitted after the 30-day timeframe, you will not be
required to re -submit an entirely new PCN (unless otherwise specified). We will continue to review and/or
process your permit application upon receipt of the requested information.
Please contact me with any questions or concerns.
