Dave,
Below is the response to your question that I received from the Hydraulic Engineer for the project:
"All proposed vertical deck drains (through the deck) on the proposed bridge will be at least 10 feet away from the top
of banks. As per NCDOT's 2016 Drainage Guidelines, there are no proposed deck drains located directly over the river.
Since the height of the deck drains over the floodplain is approximately 25 feet, the natural air movement will disperse
the water enough for it to be considered diffused flow when it reaches the ground surface below."
Thanks,
Bill

Hey Bill,
How will DOT treat stormwater from the new bridge? I cannot determine from the plans and the Stormwater
Management Plan (SWP) only states that it will be minimized. Please provide more detail. Thanks.
