Erica,
I'm trying to finish up the review on the Hwy. 220 improvements in Randolph county.
I visited the permit sites on Nov. 3 . The stream at site 3 is pretty well hammered, all the way to bedrock in places. Your
impact table mentions an 18" pipe, but my guess is that the pipe is just the conveyance to the stream, and the actual
impact is riprap at the pipe outlet shown in the drawings. Is this correct? Yes. The rip rap used for outlet protection
would be the actual impact at site three.
At site 2, the table mentions a 36" RCP and 15" CSP. I saw that the 36" pipe has fallen and needs to be reset. Is this
part of the impact? Will it be extended? Or is riprap the only impact at site 2? That appears to be the case per the
drawings.
Site two involves the re- setting of an existing 36" section of pipe that has separated from the cross pipe under the existing
road due to erosion. Also, a 15" metal slope drain pipe will outlet near this location. The 15" pipe will funnel water away
from the shoulder via a curb and gutter section. Rip Rap is being used to stabilize the stream bed and the end of the 36"
pipe. It will also act as a dissipation device for the 15" lateral pipe (site 1) and the 15" down -slope metal pipe.
Thanks for any info.
