This bioretention filter is an example of green infrastructure in a residential setting. Previously, runoff from the street ran unattenuated into the Wallkill River, creating a gully from the pavement extending into the river edge. This practice eliminated the gully erosion, and provides filtering treatment for the street runoff. So far somewhat unexpectedly, the basin does not fill, it drains through the floor as fast as the runoff enters. The practice does have an underdrain, but flows have not been observed from the underdrain.
