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 runoff from [[downspout disconnection| roof drains or downspouts]] or even upon terraces or vertical surfaces of buildings. | As they do not require connection to the earth for infiltration purposes, stormwater planters can also be used in elevated locations.
