Sean,
I’m open to continuing to monitor the situation, in hopes the outlet will naturally fill in over time.
Going forward, I hope the contractors will take extra precaution with any excavation that is needed.
Thank for keeping us in the loop,
Hannah

Tom, Hannah, and Stephen
Please see the below email from Ben and the as-built elevations of the 72” RCP. It appears the pipe
inverts where set at the correct elevations, but the ditch was slightly over excavated (possibly a
result of loss retrieval efforts). Mason and I have discussed this and we would like to avoid the
contractor having to go in and regrade the ditch at this stage. We think the pipe is buried enough on
the inlet and being that it is about at grade on the outlet, it should continue to accrete sediment
over time. We would like to continue to monitor this instead of taking immediate corrective action if
you are in agreeance. Please let me know your thoughts on this.
Thanks,

Sean,
Attached and below are the as-builts for the inverts of the ditch and 78” pipe at the US17 area. The
inverts and outlet have been over excavated during the retrieval of the sediment from the storm
event that occurred 12/22/2022 -12/23/2022. Concerns if we add material:
Inlet side will creating a head cut with most of the material washing into the pipe until an
equilibrium is met.
Outlet side adding material will impound water inside of the pipe.
There was not a note or provision to place material inside of the pipe to help equalize the
system
The typical Safe Passage Requirements for Culvert Placement permit provision was not included in
the C204553 Permits. To date the Conti has been submitting their drainage investigations for review,
which are meeting the Safe Passage Requirements for Culvert Placement.
Please advise if corrective action or monitoring of the area is required. Let us know if there is any
additional information needed.

Hunter,
That provides us the information for the 78” pipe invert is correct per the accepted drainage
investigation. As noted in the plans and drainage investigation the pipe is supposed to be buried 1’
as part of the environmental requirement. We also need the grades shot at least every 10’ for
approximately 30’ from the invert and outlet. During the retrieval of the sediment after the rain
event on 12/22-12/23 the area may have been over excavated. Currently, it appears that the ditches
on either side of the pipe were graded to match the invert of the pipe. Please provide us with the
additional information for the ditch grades. Let us know if you have any questions.
Cheers,
Ben
