Typology 2 – Rectangular back of kerb raingarden
Rectangular back of kerb raingardens are suitable to use when there is at least 1.2 metres of space behind the back of kerb that is not essential for pedestrian movement or other street functions.
Stormwater flows directly from the gutter into the raingarden, percolates through the soil and is collected in perforated pipes in the base. The soil is set down to allow for temporary ponding.
