Flood Insurance Needed? Manmade Lake, Building not in Flood Zone

[Josh Stack]

I googled for the answer but didn't find much.

I'm looking at a set of three duplexes nearby a manmade lake.  The buildings clearly are not in the flood zone but part of the parcel is.

The loan will be a commercial loan, not a Fannie/Freddie backed loan.

Will the bank require I have flood insurance?  I will of course ask them but also looking for some input from the community....
