Here in Baton Rouge, we have received a teremendous amount of rainfall these past few weeks. You could consider it excessive. But, technically, how much is excessive rainfall and how should it be dealt with?
Frequent rainfall over very long extended period of time, such as one and a half inches of rain every other day for twenty days, could be considered excessive. To the contrary, one single heavy rain event, say five inches in one day, would not be considered excessive rainfall.
