6.0    STORMWATER MANAGEMENT

6.1    Legal Point of Discharge


Refer to Engineering Drawing C6398/23/D01 attached within Appendix D for details of
proposed stormwater drainage.


Under existing conditions, site runoff from the north-western portion of the site
discharges directly as sheet flow to the Noosa River. The remaining portion of site
stormwater runoff and roofwater is conveyed from north-west to south-east as sheet and
minor channel flow towards Noosa Parade road reserve. An existing side entry catch pit
and stormwater pipe network downstream of the subject site then conveys stormwater
towards the constructed tidal canal system to the south-east. The site has been provided
with kerb adaptors at the Noosa Parade frontage.


It is proposed to direct developed site stormwater south-east towards Council controlled
road reserve and existing stormwater infrastructure.



6.2    Flooding


A copy of Council’s Flood Map for the subject site is included as Appendix E.


This map has been generated using Council’s Online Mapping Portal and indicates that
the proposed building pads are not subject to inundation by current or future flood
events. Proposed finished floor levels shall be adopted with the minimum required
freeboard to flood events in accordance with The Queensland Urban Drainage Manual
(QUDM) and Noosa Shire Council’s Development Codes.
