Typically that would be at the end of the fall. Either way, it would not have helped for Friday's storm. It just sat in one place for an hour dropping 7 inches of rain in that one hour.
FTFY
While drains may not have fixed everything fully, some places like my block have a single storm drain, and every storm it quickly gets clogged with all the twigs, dirt, and junk it picks up along the way. Once you unclog the drain it clears up the flooding pretty quickly (until it gets stuffed again).
In my case either having another drain or having the streets cleaned regularly (ha!) would help immensely. Thankfully the state is putting a storm water basin soon and that should do the trick.
