BMP structures are a part of the storm drainage system that go an extra step to help maintain water quality and protect our waterways. They are engineered to hold water back during times of heavy rain and to allow at least some of that rainfall to seep into the ground or to have pollutants and excess nutrients be removed by natural plants and microbial action before they make their way into our streams and Bay.

Maintenance requirements for most BMP structures can be fully met by following the requirements for maintaining normal storm drainage areas as listed in 3.1.11.1.
