Hannah and Brad,
Yesterday Sean and I reviewed the subject project (B-5639) and reviewed the sediment losses that
occurred after this past weekend’s rain events and were originally reported on Monday, 8/9. The
contractor had been placing borrow on the detour alignment. The silt fence and fabric (which will
eventually encapsulate the detour fill) contained most of the sediment but there were losses to the
hand clearing areas and wetlands.

The areas are identified as:
Area 1: Approximately 10’ x 10’ and 6” deep in the vicinity of Sta. -L_DET-Sta. 21+50. This has been
removed by hand tools.
Area 2: Approximately 10’ x 15’ and 6” deep in the vicinity of Sta. -L_DET-Sta. 21+50. This has been
partially removed by hand tools (the higher places) but is still partially flooded, so we asked them to
wait until the water recedes to reassess to determine if more needs to be removed.
Area 3: Approximately 15’ x 8’ and up to 6” deep in the vicinity of Sta. -L_DET-Sta. 20+00. They had
not started removal of this area yet. We discussed how much they would need to remove. We
asked them to wait until the water recedes before starting in the areas where the water is standing
(and also because it is difficult to assess how much needs to be removed). This is to avoid creating
turbidity during removal.

I update you both as removal continues. If either of you would like to make a site visit at any stage
of removal, please let me know.

Please let me know if you have any questions.

Thank you,
Anneliese

Subject: Duplin Bridge 36

Brad and Hannah,
The project inspector at the subject bridge reported this morning that the project received 4 inches
of rain this past weekend. The water is still high and therefore it is difficult to access the extent of
sediment losses. They plan to provide an update when they are able.

Thanks,
Anneliese
