Over underground infrastructure, soils prone to subsidence, or on sites considered to be pollution hot spots, it may be necessary to prevent all [[infiltration]]. Stormwater planters are "filtration-only" BMPs, similar to bioretention cells, that can be squeezed into tight urban spaces, adjacent to buildings and within the usual setbacks required for infiltrating facilities. Stormwater planters can also be used as a means of providing building-integrated LID by capturing a portion of the rainwater from the rooftop.

This type of cell can be constructed above grade in any waterproof and structurally sound container, e.g. in cast concrete or a metal tank.

As stormwater planters are often quite small and receive very rapid flow, both a [[level spreader]] and the use of mulch and stone to dissipate energy from concentrated inflow are strongly recommended.
