===Underdrain===

Stormwater planters differ from full and/or partial infiltration [[bioretention]] practices in that the storage function is provided only by the [[Bioretention media storage|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  [[Underdrains#Underdrains for non-exfiltrating practices|Underdrains]] for non-exfiltrationg practices.
