Dear Mr. Pettyjohn:
LM`.
s glee P*rnawN?ru?'
On November 25, 2009, I visually inspected the construction work on US Highway 321 in Caldwell County
and the project appeared to be in good shape. Construction work is primarily taking place at the southern end
of the project. The erosion and sedimentation control structures, vegetative covering, mulching and matting
appear to be working property.
Continue to ensure that all sediment and erosion control structures are maintained and that seeding and
mulching are performed as needed to protect downstream waters. Please refer to the attached inspection report
for additional comments and recommendations.
If you have questions, please call me at 828-296-4500.
Sincerely, n
Michael R. Parker
Environmental Senior Specialist

If yes, complete the section below:
Looked at entire project. Most work is taking place at the southern ends of the project. Some
other work such as shoulder work and repair of the slide areas are taking place along the rest
of the project.
Please continue to monitor the steep slope and blasting at the southern end of the project.
Steep slopes and sediment could pose a problem if not properly controlled. The area along
NCSR 1370 (Kirby Mountain Road) appears to be stable at the present time. This area should
be watched carefully and additional sediment and erosion measures may be required.
Continue to maintain sediment and erosion control structures to protect state surface waters.
