Good morning Stacy:
Here is my response to his comment about the intensity. I’ve calculated the runoff for a 24 hour duration storm event,
which for a 2‐year storm from the NOAA Atlas 14 data is 0.143 inches per hour. His comment about an intensity of
closer to 5 inches per hour would be applicable to a 5 minute storm duration event, which from NOAA Atlas 14 data is
4.86 inches per hour. While this does result in a higher peak runoff it is substantially less total volume of water over the
duration of the storm event. Regardless I’ve recalculated it here for a 5 minute duration storm. You can see there are
still no issues.
Respecƞully,
