As part of the proposed renovations, the existing dwelling will increase in impervious area, however the
catchment will not increase. This increase in impervious area will continue to the same outlet point via a
detention tank located in the common property (lot 0 BUP13368). The post-development catchment is
shown in Figure 3 (and Bax Engineering plan 075-028-SK02 as part of Appendix A).
