4434 Wilmington Road Garner, NC 27529
Nationwide Permit 39/58 Additional Information

Kristina Morales:
1. For the main Road Crossing, please provide more details regarding avoidance and
minimization of impacts S3 and S2 for this project. [15A NCAC 02H .0506(b)(1)]
a. It seems that the area selected intersects two streams and results in another
being completely filled in.
If this road crossing was shifted in the up-valley direction, to the Southeast, the
quantity of wetland impact would be much greater. This would likely result in all
of wetland WL 2000 being filled and approximately half of WL 1500 being filled.
Based on estimations the total wetland impact from shifting the crossing up-
valley would be approximately 0.022 acre instead of the proposed 0.006 Acre
which is over three times greater. Also, if the road crossing was shifted in the
down-valley direction, generally to the Northwest, the amount of stream impact
would be increased instead of decreased. The location chosen for the crossing
is at a relatively straight section of channel CH 100. This location would impact
approximately 66 linear feet of CH 200 and 109 liner feet of CH 100. In
summary, the proposed location for the crossing reduces wetland impacts
compared to moving in the up-valley direction and reduces stream impact
compared to moving in the down-valley direction. Additionally, the road
alignment at the stream crossing has been dictated by the City of Garner for an
eventual connection with Cook Street.
b. There also appears to be potential indirect impacts to channel 200 (Impact S3)
as water flow is cut off from the wetland.
Based on existing site conditions secondary impacts to channel CH 200
downstream of Impact S3 are unlikely. Channel CH 200 is located in the
floodplain of channel CH 100 and it is highly entrenched to the point where it
receives groundwater from bank seepage and hydric soils. Additionally, based
on field observations CH 200 did not receive hydrology, in amounts that were
more than insignificant, from the floodplain/wetland due to the entrenchment of
CH 100.

2. Please provide cross section details showing the provisions for aquatic life passage; the
culvert must be buried appropriately. [15A NCAC 02H .0506(b)(2)]
Please see the included detail illustrating proper culvert burial for aquatic life passage.
Please note that the provided exhibit shows a round culvert, however the same burial
requirements will be used for the specified box culvert at the road crossing. The
crossing has been designed to not alter dimensions, pattern, or profile of the channel
above or below the culvert. Additionally, the stream profile within the culverted area will
remain at the pre-existing slope and will allow for aquatic life movement during low flow
periods. The culvert will be installed per General Condition 11 of GC 4263.
3. Please provide detailed plans for restoration for temporary impacts, similar to those
provided for Pump Around. [15A NCAC 02H .0506(b)(2)]
Please see the included detail illustrating restoration of temporary impacts. During
excavation for the temporary impacts native materials will be stockpiled for re-use once
the construction is completed at the impact area. The mixing of top soil and sub-soils
will be minimized to the greatest extent possible. Disturbed areas will be re-vegetated
using native seed mix and will be stabilized using straw and matting. Matting will consist
of biodegradable coir/coconut fiber and will not include plastic mesh or plastic twine
within wetlands or along stream banks. If the pre-existing conditions of the stream bank
at the temporary impact are unstable/vertical the banks will be graded and stabilized at a
stable slope as shown on the attached detail. The impacted areas will be returned to the
original grade including cross-sectional morphology, pattern, and profile. Temporary
impacts in wetlands will occur using mats, where possible, to limit compaction of soils.
All temporary impacts will be completed and restored according to applicable GC 4263
General Conditions.
4. Please provide an updated site map for buffer impacts that clearly shows the scale so
that 10ft construction corridor can be verified. It was stated that the corridor would be
maintained but the provided maps do not allow me to confirm this (Detail 4: Pg 5 of
Buffer Impacts Map). [15A NCAC 02T .0305 (f)]
Thank you for taking my phone call on December 14, 2023. Based on the discussions
during our call, and subsequent emails, I believe the area of concern related to this
comment is where the permanent maintenance corridor for the sewer alignment is close
to the right top-of-bank of channel CH 500. According to the General Certification 4276
Activity Specific Condition #2 the construction corridor shall be no closer to the ordinary
high water mark or top-of-bank than 10-feet. I have attached a revised site plan/grading
plan showing the updated location of the proposed sewer line. Additional manholes
have been added to shift the sewer line away from the channel top of bank. The result
of shifting the sewer line further from the creek is a reduction in parking spaces for the
development. The entire width of the corridor will be required to be cleared and
maintained. The trenching for the sewer line will be approximately no closer than 20 feet
to the top of bank with most areas being 30+ feet from top of bank. The cleared areas
will be re-vegetated and stabilized. Due to the distance of trenching activities from the

top of bank and re-vegetation There should be no instability to the creek where the
proposed sewer corridor is adjacent to channel CH 500.
5. It appears that the permanent maintenance corridor is greater than 30ft (Buffer Impact
Detail 1: Pg2) could you please provide details, along with the table of use item in
reference, to clarify this?

The permanent maintenance corridor is a width of 40-feet. This is due to the width being
requited by the Raleigh Water and Sewer Department which will be taking over
operation of the line once construction is completed. Atlas staff verified the width
requirement with the project engineer. According to the 15A NCAC 02B .0714 Neuse
River Basin Buffer Rule, Section 11 Table of Uses:
Row y(ii) [road, driveway railroad crossing -perpendicular]
Impact greater than one-third of an acre of riparian buffer. Is allowable upon
authorization.
Row kk (iv): [Perpendicular crossings]
Permanent maintenance corridor greater than 30 feet wide. For impacts other than
perpendicular crossings, mitigation is only required for Zone 1 impacts. For
perpendicular crossings that disturb equal to or less than 40 linear feet, no mitigation is
required. For perpendicular crossings that disturb greater than 40 linear feet, mitigation
is only required for Zone 1 impacts. Is allowable with mitigation upon authorization.
Row ll (i) and (iii): [Impacts other than perpendicular]
(i): Zone 2 impacts: Deemed Allowable.
(iii): Zone 1 impacts other than those listed above: Allowable with Mitigation
Row i: Grading
Grading only in Zone 2 provided that the health of existing vegetation in Zone 1 is not
compromised: Deemed Allowable.

Based on the table of uses the road crossing is “allowable upon authorization” due to
being greater than 1/10 acre and less than 1/3 acre. The perpendicular sewer crossings
with maintenance corridor greater than 30 feet wide are “allowable with mitigation upon
authorization” with mitigation only being required for zone 1 impacts. For non-
perpendicular sewer impacts zone 2 is “deemed allowable” and zone 1 is “allowable with
mitigation upon authorization”. Lastly, grading is “deemed allowable” only within zone 2.
The impact table on the last page of the previously submitted buffer impact map
indicates mitigation for all zone 1 impacts except for the road crossing where it is not
required. No mitigation is required for any proposed zone 2 impacts according to the
table of uses.
