I have a site that drains to the river thru a storm water pumping station. The gates close and the pumps get turned on when the river reaches a certain flood stage.
1. What is your understanding for the standard engineering practice designing storm water systems per above? Do I have to design it for the 100 yr storm if the gates are closed?
2. Best guess what size pumnps would I need if I have 209cfs peak flow to the pumping station with a total volume for the 100 yr 24 hr storm being 920,000 cf?
