     2.3. Proposed Development Drainage Pattern

          2.3.1 Stormwater Concept
The development of the site has been accounted for in the master stormwater management strategy prepared for
the subdivision creating the subject lot by Cardno Lawson Treloar (15/02/08). Run-off from the site is to be conveyed
through piped drainage towards Lot 100 SP 216079, where a large bioretention basin and detention area will
provide the required treatment and attenuation of site run-off. The existing interallotment drainage point at the
north-eastern corner of the site will be the legal point of discharge for the development.

Driveways will be graded to fall towards the north of the site, entering the landscaped area along the northern
boundary as sheet flows. Inlet pits within the landscaping area will capture excess run-off from the surface, which is
conveyed by stormwater pipes to the existing inlet pit.

Roof water from the new buildings is to be drained via downpipes with outlet connections directly draining into the
proposed inlet pits.

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

     1. Noosa Shire Council Planning Scheme Policy (PSP) 6 - Engineering Design Standards;

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

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