Art,
Thanks for the update.
I’ll be covering Division 8 moving forward and I wanted to take this opportunity to introduce myself.
I look forward to working with you and receiving updates on the progress of the repairs.
Talk to you soon-

James, Rob, Ryan,

Please see below the sediment loss report submitted by the project inspector for R-3421 A&B.

Based on the projected rainfall forecast for this week I have recommended that the contractor proceed with the cleanup
and repair ASAP.

If you have any questions or concerns, please let me know and I will pass them on to the Resident Engineer’s office. I will
follow up with a site visit later this week if the weather allows.

Thanks,

Art C. King

Art,

During our erosion inspection on R-3421A and R-3421B, after a recorded rainfall of 1.11 inches, we have found several
areas of silt loss. Each spot has been documented in the attached pictures. The contractor began cleanup of offsite using
buckets and shovels. Our recommendations for repair are documented in attachments. Please advise of any additional
reccomendations for these locations.

Thanks,
Brent Dunn
