Stormwater Management Plan

7 > Conclusion

This Stormwater Management Plan demonstrates that under the proposed concept plan Stormwater
Quality and Quantity Treatment is achievable to the levels required by State Planning Policy July 2017.

Noosa Shire Council flood mapping indicates the site is not subject to flooding from any source.

The lawful point of discharge for the site is to the existing underground stormwater drainage network in
Bottlebrush Avenue.

Stormwater and roofwater runoff from the development will be collected and conveyed in a new
stormwater pit and pipe network to an underground detention tank located near the south-western side
of the site. Detained flows from the tank will outlet to a new stormwater manhole in Bottlebrush Avenue
located at opposite verge of road.

Stormwater Treatment will not be required as part of the development in accordance with the Noosa
Shire Council planning Scheme Policy and State Planning Policy July 2017.

A Trapezoidal catch drain will be constructed along the north-eastern boundary to collect and convey
upstream catchment runoff. This runoff will be collected in a stormwater pit at the eastern end of the
catch drain and conveyed through the internal drainage system.
