     2.3. Proposed Development Drainage Pattern

          2.3.1 Stormwater Concept
The internal stormwater drainage network will consist of several pits to provide collection points for upstream run-
off and enclosed courtyard areas draining under gravity and discharging via new kerb adaptors to the existing
Council infrastructure in Delorme Street.

Roof run-off from the new building will be drained via downpipes into a stormwater attenuation tank to be provided
for each unit. The tank is sized to reduce the overall developed site flows to pre-development levels, ensuring
discharge from the site minimises any impact to the downstream environment.

The roof and allotment drainage system for the proposed site shall be designed to comply with:

     1. Noosa Shire Council Planning Scheme Policy (PSP) - Engineering Design Standards – Roads, drainage and
        earthworks;

     2. The Queensland Urban Drainage Manual (QUDM); and

     3. AS/NZS 3500.3:2015 - Plumbing and Drainage Part 3: Stormwater Drainage.

Refer to Appendix A Proposed Development Concept Plan for the proposed stormwater drainage layout plan
illustrating the concept described above.



     2.4. Flood Considerations
Review of the Noosa Shire Council Intramaps flood layers including the Flood Hazards Overlay has identified that
the site is located outside of any flood or inundation areas within the locality indicating it is not expected that that
the proposed development will be subject to flooding.
