The fee was designed to mitigate the effects of stormwater run-off from impervious surfaces and improve the water quality in the Chesapeake Bay.
An excellent example of how the funds are used is in Baltimore County at Scotts Level Branch. The county used funds from the fee there to restore the shoreline of the stream, filter suburban run-off and slow stream velocity.
In the process it created important wildlife habitat that hosts migrating grassland birds in need of a refueling stop. This year some 66 bird species have been documented there, plus several butterfly and dragonfly species.
If we want to save the bay, we must address the issue of stormwater run-off, and this fee does just that.
