Flood control to keep water out of houses seems like a good idea,
but it turns out that it causes the flood control measures to keep
needing to be raised higher, and it encourages people to build
too close to flooding areas, plus
“rare and catastrophic events take place”.
Like the 2009 “700 year flood” and the
four or more floods this year
that have overflowed the Withlacoochee Wastewater Treatment Plant.
In our case, there are also the issues of widespread clearcutting
and buildings and streets with impervious cover.
The local runoff containment requirements in the various local government zoning codes may be
like levees: “flood control
structures might even increase flood risk as protection from
frequent flooding reduces perceptions of risk”.
This encourages human settlements in floodplain areas, which are then
vulnerable to high-consequence and low-probability events.
Much simpler just not to give out building permits for flood zones.
Or we could
put medical buildings right next to a creek
because it’s never flooded it never will
