The North Carolina Department of Transportation (NCDOT) proposes to conduct
secondary roadway improvements to SR 1152 (Holly Springs Road} from edge of
pavement on SR 1152 to edge of pavement on SR 1152 in Wake County. The existing
structure at Site 1 (Station 25+18-L-} is a 24 inch concrete pipe that is 28 feet long. The
stream conveys an unnamed perennial tributary that flows to White Oak Creek in the
Cape Fear River Basin (Best Usage Classification C, NCDENR-DWQ Index No. 18-7-6).
The proposed replacement structure at the stream crossing is a 54 inch corrugated
steel pipe that is 60 feet long. An additiona154 inch corrugated steel pipe that is 60 feet
long will be placed approximately 4 feet from the above-mentioned pipe (and out of the
flow line of the tributary to White Oak Creek} which will serve as a floodplain pipe.
Permanent impacts at the site associated with the replacement of the structure and
minimal amounts of rip rap to protect the structure are <0.01 acre fill in surface water and
521inear feet existing channel impacted.
The project was placed on hold by the NCDENR-DWQ by letter dated April 17,
2003. The letter states:

• The project proposes new impacts to 521ineaz feet of stream at Site 1. In
accordance with 15A NCAC 2B .0233, this project is subject to the diffuse
flow requirements for impacts to Neuse River Riparian Buffers. Please
provide a new design that shows how NCDOT plans to provide for diffuse
flow of stormwater at non-erosive velocities through the ripazian buffers.
Please note that the project is located in the Cape Fear River Basin, as
indicated on page 1 of the cover letter and on page 6 of the Pre-Construction
Notification. Therefore, the project is not subject to the Neuse River Riparian Buffers.
If you have any questions or need additional information, please contact me at (919) 560-
6081.
Sincerely,
GAG'. ~-~--~~
