tree clearing. Tree clearing areas will not be maintained and will be allowed to revegetate with woody vegetation.

3i. Comments: Unavoidable impacts to jurisdictional streams will result from the proposed roadway construction. Impacts to
streams will result from the installation of culverts to carry the streams beneath the McCrimmon Parkway roadway corridor.
Mitigation is proposed for permanent stream impacts resulting from Road Construction.

6i. Comments: Unavoidable impacts to the riparian buffers of streams SD, SE, and SH will result from the road construction. The
riparian buffers will be crossed perpendicularly to minimze impacts. According to the NRB Buffer Rules, impacts at Site 2 are
"allowable" (road crossings that impact greater than 40 LF but equal to or less than 150 LF), and impacts at Sites 1 and 3 are
"allowable with mitigation" (road crossings that impact greater than 150 LF or 1/3rd-acre of riparian buffer).
D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts to jurisdictional wetlands, streams, and riparian buffers have been avoided and minimized to the extent practical. The
alignment will tie into the existing section of McCrimmon Parkway to minimize new construction length and impacts. The
alignment has been located along the topographic ridge as much as practical to avoid larger stream and wetland systems
located in the bottomlands adjacent ot the project area. The alignment was also located intentionally to minimize earthwork and
grading required, reducing the required fill slopes along the alignment and limiting stream and wetland impacts.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Impacts to streams within the corridor will be minimized to the extent practical throughout the construction process by avoiding
stream and wetland features where practical. Equipment staging and construction access will be located in upland areas
throughout the corridor, and silt fencing will be installed around the permitted limits of distrubance to ensure all equipment is
located within the project corridor at all times near stream and wetland areas. Sediment control measures will be used to reduce
stormwater impacts to receiving waters and minimze runoff from the construction sites.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for � Yes ❑ No
impacts to Waters of the U.S. or Waters of the
State?
2b. If yes, mitigarion is required by (check all that apply): � DWQ � Corps
� Mitigation bank
2c. If yes, which mitigation option will be used for this
project? ❑ Payment to in-lieu fee program
� Permittee Responsible Mitigation

5. Complete if Using a Permittee Responsible Mitigation Plan
5a. If using a permittee responsible mitigation plan, provide a description of the proposed mitigation plan.
Mitigation credits for the proposed project will be provided from the "Morrisville Community Park Stream & Riparian Buffer
Mitigation Site" as discussed with the USACE and NCDWR and multiple meetings and in communications through late 2016
and early 2017. The mitigation site will provide 694 linear feet of stream mitigation credits, and will provide 175,028 square
feet of riparian buffer mitigation credits.
6. Buffer Mitigation (State Regulated Riparian Buffer Rules) — required by DWQ
6a. Will the project result in an impact within a protected riparian buffer that � Yes ❑ No
requires buffer mitigation?
6b. If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation. Calculate the
amount of mitigation required.
6c. 6d. 6e.
Zone Reason for impact Total impact Multiplier Required mitigation
(square feet) (square feet)
Zone 1 Road Construction 45,092 3(2 for Catawba) 135,276
Zone 2 Road Construction 26,501 1.5 39,752
6f. Total buffer mitigation required: 175,028
6g. If buffer mitigation is required, discuss what type of mitigation is proposed (e.g., payment to private mitigation bank,
permittee responsible riparian buffer restoration, payment into an approved in-lieu fee fund).
Mitigation for unavoidable impacts to riparian buffers of stream SD and SH will be provided by the "Morrisville Community
Park Stream & Riparian Buffer Mitigation Site". The mitigation site will provide 175,028 riparian buffer credits as discussed
outlined in the NCDWR closeout documentation for the mitigation site and as confirmed by NCDWR at various meetings and
in conversations held in late 2016 and early 2017. Mitigation credits have been fully constructed and closed out with
NCDWR and the USACE.
