We invest in controlling pollution generated whenever it rains to protect our own economic prosperity
Managing Rainfall Runoff
Pure Michigan
Our Actions
do not yet reflect the new realities that science
reveals
… we are living the old reality, the cost of managing rainfall runoff only includes flood control
…how we pay those costs is hard to see
…continued perception that rainfall runoff is harmless
…reluctance to confront now paying for what seemed to be free
We must manage rainwater to protect our rivers, streams, and the Great Lakes
Acting to manage rainwater is investing in our own economic prosperity
Transparency – so that property owners know what they are paying for and how much it costs
Equity – so that property owners only pay their fair
share for the service they use
Cost effectiveness – so that property owners know
that their money is being used wisely
