     2.3. Proposed Development Drainage Pattern

          2.3.1 Stormwater Concept
Roof run-off from the new building will be drained via downpipes into an internal stormwater drainage which will
carry surface and roof run-off from the proposed development to discharge via new kerb adaptor outlets to replace
the existing discharge point of the roof run-off. The kerb adaptor outlets are proposed as the Lawful Point of
Discharge for the development.

Overland flow paths along the western and southern boundary will provide fall for upstream run-off to be conveyed
around the site, while the pits within the site will provide collection points to allow for the small areas of upstream
run-off that may reach the subject site.

The remaining typically pervious areas of the site will drain as overland surface flows infiltrating into the site soils
consistent with the current drainage conditions.

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 Plan for the proposed stormwater drainage layout plan illustrating
the concept described above.
