     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 roof run-off and
nearby surface water discharging under gravity to new kerb adaptors to be provided as an outlet to Ross Crescent.
Sumps within the basement area and driveway will drain to an in ground holding tank, where they will be pumped
into the internal drainage network for discharge from the site under gravity.

With sandy soils typical of the locality, surface run-off is expected to quickly infiltrate into the surrounding soils and
not result in standing water within the site.

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.
