1.4 Site Characteristics

1.4.1 External Catchment Analyses
An investigation has been undertaken into the surrounding areas to determine the existence
and extent of any external catchments contributing flows toward the subject site. It is noted
that the upstream catchment to the development site is traversed by Elanda Street, as a
result, the flows from upstream will bypass the site via the road carriage way of Elanda
Street without contributing to the development site as external flow.




1.4.2 Existing Land Use and Stormwater Discharge
The site currently has one dwelling located at the north side of the site with existing
impervious driveway. The site falls towards the eastern boundary at an average grade of
10%, as reflected by the contour information in Appendix A. The impervious areas comprise
of the roof area of the residential dwelling, as well as the driveway area. The rest of the site
is covered by grass and trees, as shown in Table 1.1.
