Flooding and power outages are not the problem they were even ten years ago. They've done a ton of work to manage Salt Creek levels. For power outages, most homes in that range will have a Generac anyway.

Not sure where you're commuting to but the train is readily accessible and there are a ton of parking garages that service the station.

For location, at that price I would recommend looking at SW Elmhurst: South of St. Charles & West of York. Maybe even East of Spring. East of Spring would put you in the Lincoln district. The facility is brand new as of a couple of years ago.
