HomeMy WebLinkAbout20130918_Sediment loss on U-2525B_20150929 Carpenter,Kristi From:Parker, Jerry A Sent:Tuesday, September 29, 2015 3:00 PM To:Wanucha, Dave Cc:Bailey, David E SAW; Nicole Thomson (nthomson@sepiengineering.com); Thomson, Nicole J; Eason, Patty P; Mills, James M Subject:Sediment loss on U-2525B Attachments:U-2525B Sediment Loss.docx Dave, Per the telephone message I left yesterday, attached are pictures of the sediment loss that occurred over the week-end from the over three inch rainfall (and still counting) that the area received. There is at least one other area that likely has sediment in a stream on this project that is currently inaccessible due to the very, very muddy conditions. Vehicles have gotten stuck in mud trying to access the area. The pictures show the slope failure that led to sediment travelling to the toe of the slope and then washing through a pipe and depositing beyond the outlet end of the pipe. I instructed the contractor to remove the sediment using the sediment removal guidelines, up to a designated point which was approximately 100 yds downstream of the outlet pipe. The sediment has already been removed and I will forward you more pictures of the clean-up later this week. If you have any questions please call me at 336 451-6629.
