Every project, including road projects, should be required to incorporate a storage tank for rainwater, which would be allowed into the public drainage system after the storm subsides. The size of the tank and when to pump out the water are a matter of engineering calculations.
I am surprised that this design philosophy has not been implemented or even mooted since the problem of flash floods surfaced a couple of years ago. There is a cost involved, but nothing is free.
