In what ways has the Greenway project in Grand Forks (N. Dakota and Minnesota) reduced the risks associated with river flooding in that area?

Answer:

Much of the area that is now part of the Grand Forks Greenway was formerly occupied by impermeable surfaces such as roads, parking lots and buildings so that water flowing through was unable to soak into the ground. The now more permeable surfaces allow water to soak in, reducing the risks of flooding here and farther downstream.  Furthermore, the infrastructure within the Greenway has been designed so that it is not significantly damaged by flooding.
