Re: Request for Preliminary Jurisdictional Determination
Convert Existing Grade Separation at 1-95 and SR 1770 (Sunset Ave.) to an Interchange
Nash County, NC
NCDOT STIP U-5026
Mr. Ridings:
VHB respectfully requests concurrence with the attached request for buffer determination request in association
with this proposed NCDOT interchange improvement. VHB is currently under contract with NCDOT to provide
natural resources inventories, jurisdictional assessments and reporting. The project was previously delineated in
2008 by NCDOT staff. The original 2008 study area extended further in all directions and was significantly wider
from the centerlines of 1-95 and Sunset Ave. (SR 1770). VHB amended the original 2008 study area to 75 linear feet
off the proposed slope stake design, to create the 2019 study area shown in this submittal. VHB verified the 2008
potential resources (stream and wetland) delineations done by others within the new 2019 study area and flagged
additional potential resources in the 2019 study area. The proposed project is located in western Rocky Mount, in
Nash County, NC.
This project is considered a transportation project and buffer determination request will assist in avoidance and
minimization of unavoidable riparian buffer, stream or wetland impacts associated with design and layout of the
proposed project. We have attached the following information to assist with your review:
• Preliminary Jurisdictional Determination request forms
• Figures
0 1. USGS topographic map
o 2. 1989 Soil Survey of Nash County, NC
o 3A-3C. Jurisdictional features maps
• NCDWR stream forms
• Site photographs
If you have any questions, please do not hesitate to contact me at [phone]. We look forward to hearing
from you soon.
Sincerely,
VHB
