                    Figure 2.4 – Lot 2 RP 64750, roof downpipe draining towards northern boundary.

            Roof run-off from the dwelling on Lot 2 RP 153798 is similarly collected in downpipes
            however no outlet could be located within the property nor within the street drainage. It is
            assumed that this water must be discharged as overland flow on site as surface levels along
            the frontage are typically higher than within the property making gravity drainage to the
            street unlikely.

            Roof water from the garage on this property is collected and conveyed to a water tank on
            site of approximately 10,000L, with overflows discharged as overland flow within the
            property.

                         2.2.1.1.       Upstream Catchments

            Contour maps of the locality indicate that upstream surface run-off from the adjacent
            property on Lot 1 RP 153798 may enter Lot 2 RP 153798 as overland flow along the
            boundary, however no evidence of this was able to be observed on site. Roof water from
            the dwelling on the upstream property appears to discharge directly to the table drain on
            pearl street through a piped outlet.

            Surface run-off from the road reserve is typically collected in the table drains along the street
            frontage and does not appear to enter the site.
