This site-based stormwater management plan has reviewed the estimated existing and
post-developed peak stormwater flow and stormwater quality aspect for the proposed
Industrial development at Taylor Court, Cooroy.
Based on this assessment the following conclusions have been made:
Post-developed peak stormwater discharge from the development will be mitigated by
a 94.5m3 underground detention tank, placed under the bioretention basin within the
site, providing stormwater mitigation ensuring pre-development peak flow rate
characteristics.
A bioretention basin with the area of 83 m2 minimum is proposed to treat stormwater
runoff from the development sized in accordance with SPP (2017).
In summary, development of the site will result in non-worsening of stormwater runoff
quantities to properties downstream and adjacent. All stormwater will discharge to a Lawful
Point of Discharge in accordance with QUDM (2017). Furthermore, a bioretention basin and
detention tank are proposed to mitigate stormwater pollutants and mitigate stormwater
discharge in accordance with the Noosa Plan (2020).
