It wasn't me.
I remember that some residential communities had a similar code. But, it was intended to control draining swimming pools. A permit was needed, of course, and the water needed to be drained directly onto the street where in entered a storm drain.
If that is the case in this situation then there is at least a possible solution.
Last time I was in Barbados they were having a hurricane, can't imagine what kind of spillway would be required for that run off.
The beer might be Red Stripe?
