If I'm understanding this correctly, system is designed to handle at least 10"/24h in retention ponds.
They can drain 7"/24h through inlets with spillover into golf courses.
We had as much as 12" south of 44.
As mentioned above, should they overflow, streets in most cases are graded to flood first followed by yards before water reaches homes.

With hurricane Irma it was able to handle 18 inches of rain in 24hrs. Beyond what it was designed for.
