FIS Regulatory / With / Without Floodway BFE
Once again, I know nothing, so please – be gentle.
Preparing an elev. cert for a dwelling in a floodway.
Stream in question is about a mile away from dwelling. Stream has FIS w/ sections & profiles, BFE’s established. FIS has a table showing BFEs: “regulatory”, “with” & “without” floodway.
Floodway & 1% flood boundary are very nearly coincident.
In table, “regulatory” & “without floodway” BFEs are equal, “with floodway” BFE is 0.7′ higher than “regulatory” & “without floodway”.
I presume that I should use the “regulatory” values for my calculations, but assumptions make me nervous. Am I right or wrong?
Thanks in advance,
SS

I’ll bite, since you are in the floodway, you should use the “with floodway”. The other is for areas adjacent to the floodway, at least that’s how I have always done it.
