     2.3. Proposed Development Drainage Pattern

          2.3.1 Stormwater Concept
The internal stormwater drainage network will be provided to ensure collection of surface run-off as well as allowing
for capture of upstream run-off at the boundary and discharge from subsoil drainage of retaining walls.

Roof run-off from the new building will be drained via downpipes into a stormwater re-use and attenuation tank 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. Tanks of a suitable size will be provided to each
unit to comply with the relevant code and mitigate developed peak flows from the site. The tank overflows will be
connected into the internal stormwater drainage pits throughout the development.

The internal surface and roof drainage will be conveyed and discharged via kerb adaptors replacing the existing
within Safari Street, being the lawful point of discharge from the development consistent with the existing drainage
characteristics.

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.
