==Planning Considerations==

Stormwater Planters are a type of bioretention practice. Please defer to planning considerations in [[Bioretention]]

Stormwater planters may be integrated into the landscape similarly to bioretention practices. See [[Bioretention#Planning considerations|bioretention planning]].

As they do not require connection to the earth for infiltration purposes, stormwater planters can also be used in elevated locations. They are sometimes used in retrofit applications on otherwise impermeable surface, as raised beds or planters surrounding buildings. They can be employed to capture [[downspout disconnection]] or even upon terraces or vertical surfaces of buildings.

===Underdrain===

Stormwater planters differ from full and partial infiltration [[bioretention]] in that the storage function is provided only by the [[water retention capacity]] of the [[filter media]]. As such there is no storage reservoir and the only purpose to the aggregate layer is to drain water to the perforated [[pipe]]. For this, a medium aggregate as described in [[choker layer]] is recommended as it negates the need for a separating layer to the filter media. Design details can be found here n [[Underdrains#Underdrains for non-exfiltrating practices|Underdrain]] for non-exfiltrationg practices.
