Dear Ms. Higgins,
Carolina Ecosystems, Inc., on behalf of Winslow Custom Homes, LLC and CAA Engineers,
Inc., has prepared the attached Pre-Construction Notification (PCN) for the above referenced
project as an after-the-fact Neuse River Riparian Buffer Rules (NBR) authorization request.
Construction utilized non-reporting approvals under Clean Water Act Section 404 Nationwide
Permit 12 and Section 401 General Certification No. 3884. The project is a residential
subdivision located on the north side of Holden Road in Youngsville,NC.
The attached PCN form provides information for use in your review of the impacts to streams
and buffers associated with this project. Supplemental information is provided in this cover letter
and in the attachments including a Vicinity map, USGS map, Jurisdictional Features map,NRCS
map, Impact map, and Species map. CAA Engineering, Inc. has provided the attached site plans
for your review.
Proposed Impacts and Mitigation
All impacts associated with the subdivision have been avoided with the exception of a sewer line
that must run downhill to connect with an existing gravity line. The sewer line crossed two
perennial streams (both class C;NSW) with no permanent impact below ordinary high water
mark. The temporary stream impacts were 26 and 36 linear feet, respectively (total 62 linear
feet). Stream crossings were perpendicular and the permanent right-of-way will be 10 feet wide.
This is an after-the-fact permit because the clearing for the stream crossings has already occurred
and has exceeded the 40-feet maximum riparian buffer threshold to be designated as `exempt'
per the NBR. The disturbance is designated as 'allowable' under the NBR with zone one and two
impacts totaling 5,434 and 4,107 square feet, respectively. Because clearing of the construction
corridor exceeded the 40-foot exempt threshold,NC DWR requested the applicant ensure woody
trees are present. Either volunteers or plantings could be used to satisfy this request, so long as a
minimum density of 320 stems per acre is achieved. The total impact beyond the exempt corridor
is 1,482 square feet(Figure 5). To achieve a minimum density of 320 stems per acre, a minimum
of l I sap]ings must be present or planted.

On October 26, 2016, CEI visited the impact areas (Figure 6) and documented 16 trees, including
12 tulip poplar(Lirio(lemlron tulipifera), two red oak(Quercus rubra), one river birch (Betula
nigra), and one persimmon (Dio,spyros i4rginiana). Approximately 20 sweetgum (Liquidambar
styraciflua) saplings, and two shrubs, both winged sumac(Rhus copallinum),were also
observed. Excluding the shrubs and sweetgum saplings, the volunteer density of native saplings
is 470 stems per acre.No additional plantings are proposed.
If you have any questions or need additional information, please contact me at your earliest
convenience at(919) 274-5979 or Chris.hopper(i;,,.carolinaeco.com.

Permanent impacts are limited to the 10-feet maintenance corridor for the sewer line. Due to a miscommunication,the 40-
feet disturbance threshold per the Neuse Buffer Rules was exceeded during construction, resulting in an additional 661
and 821 sq ft of disturbed zone one and two riparian buffer, respectively. The above-listed impacts include these
exceedances.

D. Impact Justification and Mitigation
1.Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The project has revised its lot layout to exclude all wetland areas from future home footprints.Only the
proposed sewer line was unable to avoid crossing jurisdictional areas. Crossings were accomplished
perpendicular to stream channels:and crossing widths have been minimized to 26 feet along the UT Richland
Creek, and 36 feet along Richland Creek;the narrowest possible widths to accommodate construction.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
All erosion and sedimentation control devices were installed prior to ground disturbing activities. Clearing of the
sewer line crossings was performed during dry conditions to the extent practicable.
2.Compensatory Mitigation for Impacts to Waters of the U.S.or Waters of the State

impacts to Waters of the U.S. or Waters of the State? No

permittee responsible riparian buffer restoration, payment into an approved in-lieu fee fund).
Because clearing of the construction corridor for sewer line installation across Richland Creek and one of its unnamed
ributaries exceeded the 40-foot exempt threshold, NC DWR requested the applicant ensure woody trees are present.
Either volunteers or plantings could be used to satisfy this request,so long as a minimum density of 320 stems per acre
is achieved.The total impact beyond the exempt corridor is 1,482 square feet(Figure 5).To achieve a minimum density
of 320 stems per acre, a minimum of 11 saplings must be present or planted.
On October 26, 2016,CEI visited the impact areas(Figure 6)and documented 16 trees, including 12 tulip poplar
(Liriodendron tulipifera),two red oak(Quercus rubra), one river birch(Betula nigra), and one persimmon (Diospyros
virginiana). Approximately 20 sweetgum (Liquidambar styrociflua)saplings,and two shrubs, both winged sumac(Rhus
opollinum), were also observed.
Excluding the shrubs and sweetgum saplings,the volunteer density of native saplings is 470 stems per acre. No
additional plantings are proposed.
6h. Comments:
The construction corridor is greater than 40 feet but less than 150 feet of riparian buffer, and the permanent maintained
corridor will be limited to 10-feet wide.These crossings are`allowable', per 15A NCAC 02B .0233(6).

2d. If this project DOES require a Stormwater Management Plan, then provide a brief, narrative description of the plan:
Storm water calculations were performed for the development in accordance with standard general engineering
practices using the Rational Method for runoff estimation. Runoff from the drainage areas on and off site is collected in
storm water conveyance measures(cross pipes and ditches)and directed to discharge points. Velocity control
measures are specified to provide non-erosive velocities at discharge points. Standard erosion control practices have
been employed in accordance with approved S&EC plans.
