25 Kauri St Cooroy




1 INTRODUCTION
Hydrology and Water Management Consulting Pty Ltd (HWMC) has been commissioned by 360
Civil Consulting Pty Ltd on behalf of Calezac Pty Ltd to undertake a Stormwater Management
Plan (SMP) for a unit development at 25 Kauri Street, Cooroy. The site’s real property
description is Lot 27 on C56016.

The purpose of this investigation is to describe how the proposed development will comply with
Council’s requirements relating to stormwater quantity and quality including:

    •    Non-worsening of peak runoff from the site; and
    •    Compliance with stormwater quality treatment objectives.

Rainfall-runoff hydrology modelling of the site in its existing and proposed conditions has been
undertaken to size on-site detention storage for peak flow attenuation.

MUSIC modelling has been undertaken to size a bioretention basin that is able to reduce site
pollutant loads to achieve the required stormwater quality treatment objectives.

The stormwater strategy presented in this report has been prepared in consultation with the
project engineer, 360 Civil Consulting Pty Ltd. This report provides conceptual details of
stormwater design requirements that should be incorporated into the overall site design.
