Slide 41 of 52
Notes:
Here is a bioretention island in a parking lot. Note the curb cuts that allow the runoff to access the vegetated depression. In addition, the overflow inlet that allows large flows to bypass the system. Note that, in this particular design, the curb itself acts as a pretreatment device, allowing larger sediment particles to settle on the parking lot surface. This sediment is periodically removed by a street sweeper.
