Being fine for decades is not a useful metric, unfortunately.
If you want to know, look into the last time it was flooded.
If it has never flooded in the scope of human history, it’s possible that the danger of flooding is indeed not significant.
If it has flooded, it will likely flood again.
If it is a flood plain, it will probably flood again many, many times. Weather changes associated with climate change may exacerbate this. It would not be particularly surprising to see the variance in significant precipitation events to double, triple , or more.
In any rate, climate change aside, it would not be particularly remarkable for a flood risk that aggregates to one in ten years to not flood for 50 years running, just as it would not be unexpected if some such areas flooded each year for 3 years straight. Both of those events would be consistent with patterns that would be expected to happen in the big picture.
I know nothing of your situation, but if I were living within less than 100 feet of the altitude of a nearby river or sea, I would consider moving. Life is short, and in my tiny life I have been humanly connected to floods, tsunamis, and hurricanes within my direct circle of friends and family enough to internalize that these risks are not theoretical.
When an existential risk can be categorically eliminated from your life, it is often worth doing.
