The parking lot and alley behind 25 Market Street (Savannah, Eastern Bank, Talbott Building, etc.) is flooding and not draining during and after rain storms. This is a new phenomena. A large portion of the parking log, portions of the alleyway, and surrounding areas flood with over 1 ft. of water and ARE NOT draining. Standing water is present many, many days after rain. I believe this poses a health hazard.
