This authorization is for a modification of buffer impacts for the project as in the below
email statement:
Colleen,
I had a client and project engineer contact me about a project that was permitted
back in 2020. When they completed their "As-builts" for the project, they noticed a
discrepancy in the riparian buffer impacts. The change in the impacts per the project
engineer are due to a construction staking issue where the site was staked out
approximately 4' to the west of where it was designed. The discrepancies are shown
on the attached submitted impact exhibits with the redlines to denote the changes
(increase or decrease) in each impact area. We have also provided the As -built
Impact maps based on the surveyors clearing limits and site shift.
Please note this email is included in attachments.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project.
S&EC completed a wetland delineation and Neuse River Buffer evaluation for the
entire property in order to identify natural resources so that impacts could be avoided
& minimized to the maximum extent practicable. Proposed impacts include two (2)
road crossings, two (2) Stormwater Control Measures (SCM) discharge outlets and
one (1) multi -use path. Impact area 1 is a proposed road crossing necessary for
access to the property from the north, Morrisville Parkway. Proposed impacts include
permanent wetland and riparian buffer impacts. This access/entrance location was
determined so that the site access aligns with the existing school entrance to the
north and the existing median break on Morrisville Parkway. Shifting the road
crossing to the west to avoid/minimize impacts would result in traffic safety operation
concerns with opposing left turn movements. Fill slopes have been proposed at a
2.5:1 to minimize wetland and riparian buffer impacts. Impact area 2 is proposed
permanent wetland, stream and riparian buffer impacts for a road crossing. The
proposed culvert was extended to the upstream toe of the former pond dam that was
previously breached by others to minimize erosive conditions and avoid safety
concerns with the existing sheer slopes of the dam breach. The downstream slope
has been designed at a 2.5:1 to minimize stream and riparian buffer impacts. This
road crossing location was identified to utilize the degraded dam breach area and the
"daylighted" stream. Impact areas 3 and 5 are proposed permanent riparian buffer
impacts for Stormwater Outfalls (SCMs). Impact area 3 will drain from SCM wet pond
2 while Impact area 5 will drain from SCM wet pond 3. These impacts are necessary
to minimize/avoid erosion from the SCM's. The outfall locations have been designed
below wetlands 5 & 6 to avoid erosion and scour to the wetlands. Impact area 4 is
proposed permanent riparian buffer impact necessary for grading activity needed to
construct a multi -use path. There is an existing 6' sidewalk along the road that is
being widened to serve as a 10' multi -use path. There will be no new imperviousness
added to Zones 1 & 2 of the riparian buffer. All temporary stream impacts will be
brought back to pre construction stream bed elevations and the stream banks will be
stabilized.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Erosion control measures such as Tree Protection Fences, Silt Fencing, Sediment
Basins and Diversion Ditches will be utilized. The stream crossing will be constructed
under dry conditions with sand bags or coffer dams.
E. Diffuse Flow Plan
la. What type of SCM are you providing?*
Level Spreader
C Vegetated Conveyance (lower SHWT)
C Wetland Swale (higher SHWT)
C Proposed project will not create concentrated stormwater flow through the buffer
Other SCM that removed minimum of 30% nitrogen

lb. Describe how diffuse flow will be maintained:*
Before entering the stream buffers, concentrated flow from built -upon areas has been
routed through SCMs. In the larger storms where bypass begins to occur in the SCM
outlet structures, flow shall dissipate with an appropriately -sized rip -rap energy
dissipation pad at the outfall of the storm pipe. Bypass flows from lots and
infrastructure will not be concentrated prior to any discharge (maintains diffuse flow
characteristics).
