Montgomery County, Maryland, is the first MS4 Phase I community required to meet the stringent requirements under Maryland’s current NPDES permit cycle, including 20 percent impervious cover restoration. The program will be a model for other communities facing MS4 permits tied to the Chesapeake Bay TMDL requirements and will restore nearly 4,000 acres of existing impervious surface, all while delivering more than $300 million in improvements to seven watersheds over the next five years.
