This SWMP outlines how stormwater runoff from the site will be managed in order to not adversely
impact the receiving environment.
The proposed lawful point of discharge for the development shall be the existing stormwater
infrastructure on Hilton Tce, with a connection proposed into the existing manhole. New on-site
stormwater infrastructure shall be constructed to collect stormwater runoff and direct it to the lawful
point of discharge. Stormwater detention is not considered to be required as the proposed
development's final impervious area is considered in line with existing conditions, and as a result of the
proposed development, it is unlikely to increase the runoff to such an extent that the downstream
drainage cannot cater for the site.

Stormwater quality treatment is proposed to be managed on-site to achieve the water quality objectives
through treatment from ATLAN filter cartridges in the treatment tank. MUSIC modelling has been
undertaken to demonstrate runoff from the development site achieves the water quality pollution load
reduction targets of the State Planning Policy.

Further refinement of the proposed stormwater management measures is recommended at the detailed
design phase to ensure coordination with the final architectural layout.

By implementing the proposed stormwater management system, and providing adequate maintenance,
the downstream environment and neighbouring properties will not experience any adverse deterioration
of water quality as a result of the proposed development.
