Brian,

I am hoping that this is the last site to report sediment loss in connection with the recent rain event, but considering that
it is still raining here and I am still making rounds, I can’t guarantee it will be. Anyway, this email is to inform you that
there was sediment (mostly clean small stone) that washed into Permit Site 9 on Project U-2524C (see attached
pictures). The stone was up slope from the site and was being used by NCDOT as the foundation for the bridge approach
slab. The rain event overwhelmed the protective berm which allowed the stone to wash through several feet of bank
stabilizing riprap which then overwhelmed the silt fence at the toe of slope. The area impacted was approximately four
to six feet wide by fifteen feet long and up to three feet in depth. I have instructed the contractor to remove the small
stone utilizing approved sediment removal guidelines. Please let me know if you have any questions or comments.
Thanks.

Jerry Parker
