Johnny Cash had a song about the river rising and asks ‘how high is the river...’.
Situational awareness,
An evacuation plan should have been in place.
More so.
This campers should not have been housed in the floodway at all or in the floodway fringe area without flood proofing measures which require
elevating the structure.
If you took a national survey....there’s probably 10k structures on a flood plain. Most will make it through a 50-year cycle.
