Typology 6 – Bluestone channel raingarden tree pit
Bluestone channel raingarden tree pits are suitable to use in narrow, low speed streets where a tree can be accommodated within a gutter channel consisting of a strip of bluestone pavers.
Stormwater flow is directed along a bluestone gutter channel. The channel is set down around trees and a raised bluestone paver on the downstream side enables ponding and infiltration into filter media around the tree.
