2.1       Reference Standards and Guidelines

The development is subject to the following set of standards and guidelines:
          Australian Rainfall and Runoff (ARR) Version 4.2
          Queensland State Planning Policy (QLD SPP) 2017
          Queensland Urban Drainage Manual (QUDM) 2016
          Noosa Shire Council Planning Scheme (Noosa Plan) 2020

2.2       Catchment Hydrology

As shown in Drawings 45113-C02 and 45113-C20 in Appendix C, the previously approved
engineering plans show a single discharge point to LPOD1 in the southeast corner. In the
absence of further information, this assessment assumes a single discharge to LPOD1 in the
pre-development scenario.


Catchment plans delineating pre-development and post-development conditions are shown in
Figure 2-2 and Figure 2-3 below. Runoff from the developed site will be conveyed through the
pipe network and overland flows. Runoff from Catchment 1 (shown in purple) will be conveyed
to a combined bioretention and attenuation basin. This basin is located at the southeast corner
of the site and designed to treat and attenuate flows prior to discharge at LPOD1 into the
stormwater reserve. Runoff from Catchment 2 (shown in yellow) represents the area which is
unable to be directed to LPOD1 through the pipe network and overland flow, which will
discharge to LPOD2 on the northeast corner.
