Montgomery County Department of Environmental Protection


montgomeryctyMontgomery County Department of Environmental Protection (DEP) is responsible for the water quality of more than 1,500 miles of local streams and rivers in the County that eventually feed into the Chesapeake Bay.  Our main goal is to minimize the impacts of urban stormwater by:

  • Restoring impervious area not treated to current standards;
  • Implementing a robust inspection and maintenance program for more than 10,000 stormwater facilities in the County; and
  • Educating the more than 1 million residents and thousands of business owners on how to minimize their impacts on their local waterways.

Montgomery County is a leader within the state and Country on aggressively implementing watershed restoration using green infrastructure (GI) and other innovative stormwater treatment techniques.  Our GI initiatives provide sustainable stormwater management, more livable communities, and the creation of a skilled green workforce.
