David,
Yes. I double-checked and 19.30 cfs is a conservative estimate of the flow to the channel combining the TR-55 flows
with rationale for the offsite drainage area.
If the rational flow was taken from the pipe calcs and (9.03 cfs from pipe 114) and 5.27 cfs from offsite using a i of 6.54
in/hr the total flow would be closer to 14.3 cfs for the 10 year so 19.3cfs is a good conservative calculation.
Thank you,
Jonathan

Jonathan,
Please confirm that all drainage areas, including the 0.96ac offsite area (Sheet C6) are being accounted for in the channel
designs - channel A -A & C-C.
Thanks,
David James
