According to Council standards, the maximum discharge flow rate to a Lawful Point
of Discharge is 25l/s in a 1% AEP event. The submitted documentation indicates that
the maximum site discharge to each kerb adapter is 14l/s in a 5% AEP event. Council
are concerned that the discharge flows from each kerb adapter in a 1% AEP event
may create a worsening of existing drainage conditions and potential traffic hazards.

Information Required
Provide additional detail considering the discharge rate in a 1% AEP event and
demonstrating that this discharge rate will not create a worsening of conditions or
potential creation of traffic hazards along Coral Tree Avenue if a 1% AEP event
occurred. This detail must be prepared by a suitably qualified person (RPEQ –
Registered Professional Engineer of Queensland).
