Hi Perry, and thanks for the email. I reviewed the proposal to resolve permit non-compliance at the Huffman Point
culvert and I tentatively agree with your plan. Could you send a plan/profile view showing the concept, including the
baffles, rip rap changes and notched log sill?
Also, would local government be ok with the baffle installation as the pipe is sized to carry a specific storm event and
any material (baffle, or sediment build up) would reduce the capacity?
Thanks
-Dave Bailey

Good afternoon Sue and David. This email is in regard to the non-compliance for the project referenced above. Please
see below for a brief conceptual outline of the proposed remedy, as well as some representative photographs. We have
confirmed that this approach is satisfactory with the project engineer (cc'ed).

1. Leave upstream as it is; accumulation should occur over time as a result of activities below:
2. Install brick baffles at each drop inlet location (upstream side of each junction spanning the width of the flat spot).
From inlet, the first one should be 1-3 inches above the invert. The second one should cause 1-3 inches of back water on
the first baffle.
3. Install baffle on splash pad with an elevation sufficient to cause 1-3 inches of back water.
4. Establish a channel through the rip -rap pad with a modest slope that is field adjusted to the sill- see next item.
5. Install a notched log sill at the end of the rip -rap pad with a 3-8 inch drop which should cause 1-3 inch backwater at
splash pad. Nearby tree has been marked for this use- photo included- (24" Green Ash).
Don't hesitate to let me know if you have any questions about the provided information.
Best regards,
Perry Isner
