     2.3. External Catchments
Topographic data for the region shows that the site receives runoff from an existing dwelling located
at 47 Maple Street which falls east towards the proposed development site. The run-off is conveyed
as surface run-off which discharges to Myall Street under the existing conditions. It is proposed that
this surface run-off will be captured within the drainage system developed for the site to prevent the
surface run-off causing nuisance flows within the development. The run-off will then be discharged
into Myall Street in a manner consistent with the existing drainage patterns.




     2.4. Proposed Development Drainage Pattern

          2.4.1 Stormwater Concept
Stormwater run-off from the site will be managed through a combination of rainwater reuse,
stormwater detention tanks and an end of line bioretention swale to treat run-off from the
development prior to discharge from the site into the legal point of discharge for the development,
being the Myall Street road reserve.

Stormwater drainage lines will be installed to captured surface run-off from the driveway and
hardstand areas throughout the proposed development area.

Roof water from the new buildings is to be drained via downpipes into a 50kL rainwater reuse tank.
The tank will be connected to internal non-potable internal and external demands. Overflows from
the reuse tank will be diverted through a stormwater detention area with a further 50kL of attenuation
storage that is used to reduce the overall developed site flows to pre-development levels.
