                    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 and
            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

            Surface run-off from the upstream adjacent property on Lot 1 RP 153798 is expected to
            enter Lot 2 RP 153798 as overland flow due to the observed absence of any existing
            drainage infrastructure and the topography indicated by contour maps, however on site
            confirmation of runoff was not achieved due to lack of favourable conditions. 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.

                                                                                                            Page 4 of 33
