Much of what made the camp special also put it at heightened risk as the river rose to record levels, a Post investigation found.
The thing about flash floods is you need to move before the flood reaches you. Being aware of it doesn’t do much good if you don’t.

To what end?
We can’t just kick people out of their existing homes or shut down businesses because the maps changed around them. We allow existing structures to remain, but if they’re wiped out in a flood we don’t allow them to be rebuilt.
The tricky part is when you get outside of cities into counties, where there’s generally no permits required for building structures. It’s the utilities and subdivision improvements that get attention because they require government involvement.
And strictly speaking, development in the floodplain is prohibited by FEMA, not the county. So the county will tell you “no” if you ask, but they aren’t actively hunting for it.
In cities with code enforcement and building permits in a smaller area of land it’s a little easier, but even then in my tiny city it’s hard to find everything that gets done illegally. It’s usually spotted when the neighbors complain, or if our inspectors happen to see it while looking at a neighbor’s property.
Just last week we found someone that had filled in a detention pond, scraped all the trees out of the back of their lot (trees provide erosion control and friction to slow down and spread water), and added about 1500 square feet of concrete (speeds up water flow and reduces amount absorbed into ground) when the neighbor asked our arborist to identify which trees needed to come down for fire safety.
Im not sure building is completely forbidden. I was looking into propery and you could build on it if the structure was elevated which of course costs way more money, but it was possible.
There’s some nuance on whether it’s floodplain or floodway.
It gets technical, but the easy answer is that floodplain us where the waters will rise, while floodway is the path along which water is intended to travel. Lots of the time, the floodplain and the floodway are the same thing, but not always.
Development in the floodplain can sometimes be achieved through a floodplain development permit with a no-rise certification (there will be no net rise of water level in event of a flood caused by the development in the floodplain)
Development in the floodway is generally a hard no, because the floodway is where you want the water to go, and you want water flowing fast in the floodway to clear space for the water coming in behind it. Putting structures on stilts increases friction and slows water down, causing it to back up more upstream.
thanks. It is a distinction I had not thought about. Im pretty sure I could see both terms and if not in the same space close enough to each other, then my brain would think it was referring to the same thing.
