just for explicit, the Personal license there grants CC-SA use, is
that compatible with old & proposed new OSM terms?

Here in the US there is an official federal definition of Flood Prone
line, within which flood insurance disclosure is required of
Realtors(tm). Reading a single flood line from a photo - which may not
be at crest, may be an annual, a 20year, or a 50year event, will be
very low fidelity in comparison.
