Urban stream, or

series of mini-detention ponds?

Roadway median, or bioswale?

Street Planter, or Bioretention Cell?

Parking, or surface infiltration with subsurface practices below?

Deep Soil Tillage as a BMP

Sidewalk, or infiltration trench?

Lawn, or stormwater infiltration bed?

Communication
