For example, as a means of stormwater control, public and private interests in New York City (including one auto company, Toyota) determined to plant a million trees in 10 years. They achieved that goal in eight years.
In the metro Detroit area (home of three auto companies), large-scale tree planting has been forsaken out of preference for huge concrete and steel projects like the so-called retention-treatment basins (RTBs). Nevertheless, downstream pollution, including sedimentation and turbidity, continues to be problematic.
|Kuhn RTB - Oakland County, Michigan|
One such, the massive Kuhn RTB (formerly known as Twelve Towns) in Oakland County, recently expanded, continues to divert partially screened and treated, sediment-laden surges down the Red Run Drain to the Clinton River and on to Lake St. Clair when overwhelmed by heavy rainstorms, instead of pumping the effluent to the Detroit Wastewater Treatment Plant as usual.
Better water quality in Great Lakes AOCs can be hastened by greater reliance on green infrastructure.
