               4.2.1.2. Bioretention Areas
A 20m² bioretention areas is to be provided along the southern boundary in the lower portion of
the development, to capture and treat surface run-off from the driveways as well as the outflows
from the attenuation tanks. The bioretention areas are modelled in accordance with the Water by
Design MUSIC Guidelines 2018 with the node configuration for one of the areas shown below in
Figure 4.5 – Bioretention Node details.

A bioretention area is to have a filter media depth of minimum of 700mm to ensure deep rooting
trees and plantings are able to be established without impacting the subsoil drainage lines in
accordance with the Water by Design Bioretention Technical Design Guidelines v1.1 (2014). A 1m
filter media depth has been proposed for the swale to ensure adequate depth for deep rooting
plantings and trees.
