Thanks for the heads up and details, Nikki. Your plan moving forward is reasonable.
Once the water level drops and safety issues are addressed please send an update on
the next steps.

Subject: [Non-DoD Source] Bridge No. 40 over SR 1116 (Bishop Rd) in Guilford County
Good afternoon everyone -
Please see the attached document that I pulled together. This is for a bridge to culvert
replacement on the mentioned road. The recent rain has swollen Hickory Creek to the
point that it has not only overtopped the impervious dikes in place for the project, it has
subsequently moved a concrete barrier. The pictures detail the site as it was this
morning. The contractor has a priority punch list which includes placing larger sized

sand bags (the big round ones) in the "hole" that is noted on the first picture to try and
force the water into the diversion pipe. We are also hoping to keep that bank where it
is. On the slope face that is currently exposed, plastic will be laid to prevent any
additional erosion from the expected future rain events in the next day or so. Also note,
there is a diversion berm up above that area which captures any stormflow running
down the road; so, the only stormwater hitting that bank is what falls from the sky.
Several things have gone wrong on this site, not the least of which was a collapse of the
near bank at the abutments (which has now created a safety hazard that needs to be
addressed so no one gets hurt or un-alived). The erosion control measures were
installed per plan and were functioning. Everything just was overwhelmed. In the work
area, the forms were laid for the wing walls and the bottom of the culvert so it is our
hope that any 57 stone or sediment that washed is trapped in those forms. We won't
have a better idea how bad this is until the rain stops and the water level drops.
I am not sure how much rain this area received; I'll defer to Chris or Kim to weigh in on
the actual number.
In short, the entire work area is flooded and the contractor is working to
stabilize/reduce exposure in the work area that would otherwise be dry.
I'll keep you all posted as the week progresses.
Feel free to give me a call with any questions or concerns.
Nikki
