What Is Green Infrastructure?

It captures, absorbs and stores rain and melting snow, taking on numerous shapes and sizes from 55-gallon rain barrels to trees and porous pavers for parking lots, driveways and sidewalks. Green roofs can top buildings and bioswales can line city streets.


• Helps protect rivers and lakes from water pollution.

• Keeps stormwater from becoming someone else's headache downstream.

• Reduces the risk of basement backups and sewer overflows.

Our Goal

We have an aggressive goal and we need your help! It's to create, by the year 2035, enough green infrastructure in our region to capture 740 million gallons of water every time it rains. Why? To reduce water pollution and improve our rivers and Lake Michigan. Yes, 740 million gallons is huge, but consider this:

One Inch of Rain on MMSD's Service Area = 7.1 Billion Gallons of Water.
