For this scenario, stormwater quality treatment will be provided by multiple bio-retention basins located in
surface car parks, the southern area of the site and in the southern round-about. The drainage corridor
present in the OS7 corridor has also been utilized for its natural treatment properties. The common adopted
bio-retention parameters are listed in Table 3-5.
