Stormwater management facilities are structures that are used to remove pollutants, prevent stream damage and erosion, prevent flooding, and protect public health. The structures can be on the surface (e.g., wet and dry ponds, bioretention basins, sand filters) or underground (e.g., infiltration trenches, oil-grit separators, and underground storage structures). There are more than 4,000 stormwater facilities in the County. The first link connects to the DEP Stormwater Facility Maintenance Program that can answer all your questions about stormwater management and stormwater facilities.

The second URL provides a list of the various types of stormwater facilities in the County, where they can learn about each facility, how they are maintained and other resources.
