            4.2.1.1. Bioretention Areas

            Two 6m² bioretention areas are to be provided within each property to capture and treat
            surface run-off from the driveways as well as overflows from 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 4.9 –
            Bioretention Node details.

            Table 4.2 – Bioretention Area Plantings below (based on the Brisbane City Council Water
            Sensitive Urban Design Engineering Guidelines) presents a sample of suitable plants that
            shall be used to provide effective nutrient removal in the bioretention areas.
