Dear Sir:

The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge No. 170
over a Prong of Big Alamance Creek (Alamance Creek) on SR 1145 (Pond Road) in Alamance
County. The project will consist of replacing the existing one-span, 36-foot structure with a 13-
foot by 7-foot single-barrel Reinforced Concrete Box Culvert (RCBC) on roughly the existing
alignment. An on-site detour will be employed.

Along the L-line, proposed Site 1 impacts include 101 linear feet (ft.) of permanent fill associated
with the installation of the RCBC and rip rap at the inlet and outlet of the culvert; 117 linear feet
of temporary stream impacts; and 88 linear ft. of bank stabilization (the bank stabilization runs
concurrent with temporary impacts). Site 2 impacts include 8 linear ft. of bank stabilization and
50 linear ft. of temporary stream impact.

Proposed buffer impacts include mitigable Road Crossing impacts along the Prong of Big
Alamance Creek (Site 1) totaling 7,678 square ft. in Zone 1 and 2,381 square ft. in Zone 2 and
mitigable Impacts Other Than Road Crossings along Big Alamance Creek (Site 2) totaling 3,997
square ft. in Zone 1 and 4,028 square ft. in Zone 2. Additionally, there will be allowable
Aerial/Perpendicular utility buffer impacts totaling 823 square ft. in Zone 1 and 1,233 square ft.
in Zone 2 along the Prong of Big Alamance Creek.
