1 INTRODUCTION
This Site Based Stormwater Management Plan (SBSMP) has been prepared for the proposed
Townhouse Development at 99, 101 & 105 Eumundi Noosa Road, Noosaville.

This SBSMP has been prepared to investigate the effects the development will have on stormwater
quantity and quality.

The objective of this SBSMP is to ensure that there is no adverse impact by the development on
the environmental value of the receiving waters during the construction and operational phases
of the development. This SBSMP will also provide recommendations to ensure that the post-
development peak outflow conditions are not greater than the pre-development peak outflow
conditions.

In order to achieve this objective, this SBSMP:

    1. Describes the environmental setting of the development site and precinct;
    2. Describes the nature of the proposed development as it relates to stormwater quality;
    3. Calculates the peak flows for both pre and post-development conditions;
    4. Calculates the detention volume required to achieve the pre-development outflow in the
       post-development state; and
    5. Identifies potential sources of contaminants and describes the management techniques
       designed to be employed on the site to achieve the water quality objectives.


The proposed development has been assessed against the following guidelines and planning
documents:


    1. State Planning Policy 2017 (SPP 2017);
    2. Urban Stormwater Quality Planning Guidelines 2010;
    3. The Queensland Urban Drainage Manual (QUDM); and
    4. The Noosa Council Planning Scheme.
