Dwight -- not too many years ago, some storms like the one you describe hit the Duluth-Superior area north of you. A number of residential basements flooded after 4 inches of rain fell in less than an hour. My cousin and the mayor were both impeached from their mostly volunteer jobs because the ditches and 100 year-old sewers couldn't handle the volume of water!
While we were at Pond Boss IV, we had 100 ton of gravel spread on our driveway. When we got back, the driveway looked worse than before we left. Our friend who delivered the gravel thought we might not believe that he actually delivered any gravel. He came over with his road grader to pull lots of the gravel back into the driveway. It still looked pretty bad. Oh well, that is weather. I guess that is why pumps, culverts, and tractors were invented.
Hopefully you and the feline crew have not floated away.
