We just had 6" of rain in less than an hour. That is the most we have had in 30 years. We have had several 4"/ hour and have prevented it from getting in the house by landscaping ever since we failed the first time. This time we got a bit damp.
While I was up to my knees in the yard keeping the water from backing up, I could have been rafting the streets.
That is supposed to be a flower bed, not a waterfall.
