How well do residents protected by 100-year levees
understand their true level of risk?
The Question

Why does it matter?
Behaviorin an emergency is tied to risk perception
Floodlossestend to belarger where people are unaware
Exposing people to involuntary risk means people cannot choose
to avoid the threat.

What does it all mean?
Residents are exposed to involuntary risk
People ofall levels of income/education are unaware
(not just low-income/education)
Perception that 100-year standard protects from
all flooding.
Implications for policy, and for all of us.

I need information. This opened my eyes.
Plus, I need to check whether this area is in a
flood area.

The idea is to design spaces in landscapes
that communicate water and risk.
