Re: Buffer Authorization for Parkview Subdivision Phase 14
City Road, Clayton, NC 27520
PIN#: 165912-87-3234
Dear Sir/Madam:
Please find attached the PCN, permit drawings, and supporting documentation for the Parkview
Subdivision Phase 14, a proposed residential subdivision located in Clayton, North Carolina.
Parkview Subdivision Phase 1 — 13 was permitted under NWP 29 SAW -2015-01165 and
DWR#15-0539 authorizing the fill in a UT to Sam's Branch for 130 LF associated with a road
crossing, 16,135 ft= of Zone I impact and 4.092 ft= of Zone 2. This PCN requests an additional
Zone l impact of 639 W and Zone 2 impact of 3,297 ft= associated with a road crossing, a 10'
wide sewer utility maintenance corridor, and minor grading activities. Buffer Impact Area 1
consists of 1,522 ft'- of Zone 2 impacts associated with minor grading. This area will be
revegetated and allowed to return to its natural state. Buffer Impact Area 2 consists of 1,349 ft=
of Zone 2 impacts associated with the construction of a road and a retaining wall. The roadway
was designed to be as close as possible to the property boundary line in order to avoid any Zone 1
and stream impacts. There are no other access points to this area that would avoid any stream or
riparian buffer impacts. Buffer Impact Area 3 consists of 639 ft= of Zone 1 impacts and 426 ft= of
Zone 2 impacts associated with a gravity sewer maintenance corridor. The permanent
maintenance corridor was reduced to 10' wide through the riparian buffer area. No temporary or
permanent stream impacts are proposed since the sewer crossing will be installed using jack and
bore under the stream.
Stormwater and Diffuse Flow
The proposed development is subject to the Nutrient Sensitive Waters (NSW) stormwater
regulations administered by Johnston County, The Town of Clayton has an intergovernmental
agreement with Johnston County for stormwater review and approval for new developments. Full
construction plans, stormwater calculations, and nutrient calculations will be sent to Johnston
County concurrently with this PCN for approval.
If any additional information is needed, please advise.

6i. Comments: To minimize the buffer impacts, the roadway was located as close to the adjacent property line as possible
which avoids any stream and zone 1 impacts. In addition, a retaining wall will be constructed in order to avoid any grading in
zone 1. Also the sewer maintenance corridor was reduced to 10' through the riparian buffer. The sewer will be installed using
jack and bore to avoid any temporary impacts to the stream and minimize buffer disturbance.
