           OVERLAND FLOW PATH


An existing stormwater overland flow path is located along the rear eastern boundary of the property. From
the information provided in the Aquaintel report and the plans of the original project design (Greenhaven
Projects No. GH2019/14; Noosa Council Approval REC14/0007 &OPW14/0253) this channel has been designed
to capture overland flows and channel them to the infiltration system via a letterbox opening in an existing
900x600 field inlet pit. It is expected that this drain along with the installed 2/150dia PVC stubs would capture
and direct the design storm events (up to and including the 1% AEP) in to the infiltration system.

With the proposed development reshaping the fall of the lot to numerous localised areas, it is intended to pipe
any runoff from the site via internal roof water systems to the infiltration system or street frontage. This would
negate the need for the cut-off drain along the rear of the property and extinguish the need for an easement
over the same.
