I personally am on the second floor of this complex, though I have been through a flood here in 2000. The building I now live in has never flooded but all units flooded during this storm. No matter how low the water may seem it can have seriously damaging effects. Flood water should always be taken seriously.
I walked in this rushing water and it has a strong current to it. A smaller person than I, such as a child could easily we swept away.
