Re: NCDOT Wake County C202232
Bridges Over Austin Creek and Smith's Creek and Approaches on SR-2033
& I Section of SR-1945 (Averette Road)
SUBJECT: Dewatering Options
As you know, we are having problems dewatering for ourjack and bore operation at Austin
Creek. Our subcontractor has installed 20 If of pipe starting from the bore pit south of the creek
working north towards the creek. .
Saturday, we noticed a sump hole in the creek that was draining water. As it drained, it would fill
the boring pit and level off at the same elevation as the creek. We had to stop our pumping
operation since we could not keep up with the constant now from the creek.
We are proposing two options to dewater the boring operation as presented to us by Stocks
Engineering (see attached drawings)
Option 1: Place impervious fabric over the sump hole in the creek from edge of creek to edge of
creek and 10 ft each side of the hole. Place sandbags around the perimeter of the fabric to hold it
in place and to keep water from flowing underneath the fabric. Water in the creek would
continue to flow over the top of the fabric and the sandbags.
Option 2: If option I didn't' work we would lay three 24" pipes along the length of the creek 10
ft each side of the sump hole. We would then construct sandbag headwalls at each end of the
pipe. Creek water would be channeled into the pipes thus bypassing the sump hole.
Both of these options would have minimal impact on the flow of the creek. Therefore we hereby
request permission to continue forward with this plan.
Sincerely.
