Issue – Stormwater Discharge
Council has concerns the proposal is increasing the sites impervious area and the site is falling away from the
street.
Information Required
b)     Demonstrate a lawful point of discharge by providing a stormwater management plan prepared by a
       suitably qualified person.

RESPONSE:
A Hydraulic Engineer will be engaged to provide a Stormwater Management Plan to demonstrate lawful point
of discharge and how the stormwater will be managed. We request that the above be a condition of approval
for submission to Council for approval prior to the issue of a Decision Notice Approval for Building Works. We
suggest the following condition be imposed:

Prior to the issue of a Decision Notice Approval for Building Works, a Site Based Stormwater Management Plan
prepared by a suitably qualified person is to be submitted to Council for approval. The site based stormwater
management must address but not limited to:

- engineering design drawings, including calculations and certifications of the design, demonstrating
compliance with Queensland Urban Drainage Manual current at the time of development, Council’s
Development Manual (current at the time of development) and this Decision Notice;

- The stormwater design is to provide for the developed flows from the site to be piped to a Legal Point of
discharge.

Furthermore, the inclusion of rainwater tanks within the undercroft assists with reducing the stormwater
discharges as this potable water will be used for landscaping, outdoor use and to top up the swimming pools
therefore also reducing the reliance on town water for gardens and swimming pools.
